KlegermanAbstract: Once thrombi have formed as part of the pathology defining myocardial infarction, ischemic stroke, peripheral arterial disease, deep venous thrombosis or other embolic disorders, the only clinically meaningful thrombolytic agents available for reversing the thrombogenic process are various plasminogen activators. These agents are enzymes that reverse fibrin polymerization underlying the coagulation process by converting endogenous plasminogen to plasmin, which cleaves the fibrin network to form increasingly smaller protein fragments, a process known as fibrinolysis. For the most part, the major clinically used thrombolytics, tissue plasminogen activator, urokinase and streptokinase, as well as the experimentally investigated agent staphylokinase, are the products of recombinant DNA technology, which permits molecular optimization of clinical efficacy. In all cases of molecular optimization and targeting, however, the primary challenge of thrombolytic therapy remains hemorrhagic side effects, which are especially devastating when they occur intracerebrally. Currently, the best strategy to ameliorate this adverse effect is nanoparticulate encapsulation or complexation, and many strategies of this sort are being actively pursued. This review summarizes the variety of targeted and untargeted thrombolytic formulations that have been investigated in preclinical studies. Full text PDFCite this article: Melvin E. Klegerman.

The prognosis of GC is not always satisfactory because of late diagnosis. Scholars are keen on discovering novel accurate and economical biomarkers in body liquids for GC screening to detect and evaluate the lesion before the results of imaging techniques are obtained. While traditional serum assays have limited sensitivity and specificity, gastrointestinal juice may provide relevant specific biomarkers because of its close contact with the tumor. Herein, the current progress in the relationship between gastrointestinal fluid analyses and GC is systematically and comprehensively reviewed. The detection of gastric juice pH, fluorescence spectrum, cytology, Helicobacter pylori-associated markers, nitrosamines, conventional tumor markers, amino acids, proteomics, microRNAs, long noncoding RNAs, protein-coding genes, vitamin C, etc., and combination tests of different category markers could provide important diagnostic and prognostic clues for gastrointestinal diseases. Particularly, early GC may be efficiently screened using gastric juice. Gastrointestinal fluid examination could also predict the adverse effects of postgastrectomy, such as pancreatic leakage, fistula, and abscess. Gastric fluid markers should be further studied to reveal the early predicators of malignancy and complications. The methods for obtaining the samples of gastrointestinal juice with minimum incision should also be comprehensively investigated. Full text PDFCite this article: Lei Huang,Aman Xu.

Frontiers of Medicine, 2017. 11(1): 20-31 Innovative development path of ethnomedicines: the interpretation of the path DOI: 10.1007/s11684-016-0495-2Zhaoyun Zhu,Dehuan Fu,Yali Gui,Tao Cui,Jingkun Wang,Ting Wang,Zhizhong Yang,Yanfei Niu,Zhennan She,Li WangAbstract: One of the primary purposes of the innovative development of ethnomedicines is to use their excellent safety and significant efficacy to serve a broader population. To achieve this purpose, modern scientific and technological means should be referenced, and relevant national laws and regulations as well as technical guides should be strictly followed to develop standards and to perform systemic research in producing ethnomedicines. Finally, ethnomedicines, which are applied to a limited extent in ethnic areas, can be transformed into safe, effective, and quality-controllable medical products to relieve the pain of more patients. The innovative development path of ethnomedicines includes the following three primary stages: resource study, standardized development research, and industrialization of the achievements and efforts for internationalization. The implementation of this path is always guaranteed by the research and development platform and the talent team. This article is based on the accumulation of long-term practice and is combined with the relevant disciplines, laws and regulations, and technical guidance from the research and development of ethnomedicines. The intention is to perform an in-depth analysis and explanation of the major research thinking, methods, contents, and technical paths involved in all stages of the innovative development path of ethnomedicines to provide useful references for the development of proper ethnomedicine use.

In addition to affected extremities, patients may also present microstomia, decreased temporomandibular joint mobility. Although the etiology of AMC is unclear, any factor that decreases fetal movement is responsible for AMC. Thus, accurate diagnosis and classification are crucial to the appropriate treatment of AMC. The development of ultrasound technology has enabled prenatal diagnosis. Very early treatment is favorable, and multidisciplinary treatment is necessary to improve the function of AMC patients. Most patients require surgery to release contracture and reconstruct joints. However, perioperative care is challenging, and difficult airway is the first concern of anesthesiologists. Postoperative pulmonary complications are common and regional anesthesia is recommended for postoperative analgesia. This review on AMC is intended for anesthesiologists. Thus, we discuss the treatment and perioperative management of patients undergoing surgery, as well as the diagnosis and classification of AMC. Full text PDFCite this article: Lulu Ma,Xuerong Yu.

Frontiers of Medicine, 2017. 11(1): 48-52 RESEARCH ARTICLEPoor adherence to P2Y12 antagonists increased cardiovascular risks in Chinese PCI-treated patients DOI: 10.1007/s11684-017-0502-2Yang Sun,Chenze Li,Lina Zhang,Dong Hu,Xudong Zhang,Ting Yu,Min Tao,Dao Wen Wang,Xiaoqing ShenAbstract: Low adherence to secondary prevention medications (ATM) of patients after acute coronary syndrome (ACS) is associated with poor clinical outcomes. However, literature provides limited data on assessment of ATM and risks associated with poor in Chinese patients with ACS. In the current work, ATM was assessed in consecutively recruited patients with ACS in Tongji Hospital from November 5, 2013 to December 31, 2014. A total of 2126 patients were classified under low adherence (proportion of days covered (PDC)50%) and high adherence (PDC50%) groups based on their performance after discharge. All patients were followed up at the 1st, 6th, and 12th month of discharge while recording ATM and major adverse cardiac events (MACE). Bivariate logistic regression was used to identify the factors associated with ATM. Cox regression was used to analyze the association between ATM and MACE within one year after discharge. Results showed that coronary artery bypass grafting (CABG) alone had significantly lower proportion of high adherence to P2Y12 antagonists (83.0% vs. 90.7%, P0.01) than patients treated with percutaneous coronary intervention (PCI) only. Moreover, in patients undergoing PCI, high adherence to P2Y12 antagonists decreased the risk of MACE (hazard ratio=0.172, 95% confidence interval: 0.039–0.763; P=0.021). In conclusion, PCI-treated patients are more prone to remaining adherent to medications than CABG-treated patients. High adherence to P2Y12 antagonists was associated with lower risk of MACE.

This study investigated the clinical manifestations, laboratory findings, and treatment of patients with AA-associated chronic DIC (AA-DIC) and explored the mechanisms, duration, and therapeutic response of AA-DIC. We retrospectively reviewed the medical records of 235 AA patients admitted at the Peking Union Medical College Hospital between September 2009 and January 2015. The patients were classified as those with DIC (AA-DIC) and those without DIC (non-DIC). The AA-DIC group showed a significantly higher proportion of female patients and a significantly longer AA disease course than the non-DIC group did. The AA-DIC patients presented mural thrombi, dissecting aneurysms, a family history of AA, and diabetes significantly more frequently than the non-DIC patients did. Furthermore, multiple regression analyses revealed that sex, mural thrombus, aneurysm type, diabetes, and stent surgery are possible independent risk factors for AA-DIC patients. Fifty-two (22.1%) patients presented AA-DIC. Among these patients, 43 had non-typical DIC and 9 had typical DIC; the mortality rate of the latter was 22.2%. The mean age of the patients with typical DIC was significantly higher than of that of patients with non-typical DIC. The non-typical DIC patients also presented abnormal coagulation disorders of varying degrees. Furthermore, heparin or low-molecular-weight heparin improved the clinical symptoms and laboratory parameters in patients with AA and typical DIC. Thus, chronic DIC should be considered in patients with AA. Full text PDFCite this article: Yun Zhang,Chen Li,Min Shen,Bao Liu,Xuejun Zeng,Ti Shen.

Frontiers of Medicine, 2017. 11(1): 62-67 Improved control of hypertension following laparoscopic fundoplication for gastroesophageal reflux disease DOI: 10.1007/s11684-016-0490-7Zhiwei Hu,Meiping Chen,Jimin Wu,Qing Song,Chao Yan,Xing Du,Zhonggao WangAbstract: This study aims to determine whether successful laparoscopic fundoplication for gastroesophageal reflux disease (GERD) can improve the control of hypertension. We conducted an observational study of GERD patients with hypertension. The esophageal and gastroesophageal symptoms of these patients were successfully treated with laparoscopic fundoplication, as measured by the reduced GERD symptoms and proton pump inhibitor consumption. A hypertension control scale was used to classify the use of antihypertensive medications and the quality of blood pressure control before and after anti-reflux surgery. Wilcoxon signed-ranks test was used for the statistical analyses. Seventy GERD patients were included in the analysis and followed up for a mean period of 3.5±1.4 years. Prior to surgery, all participating patients were taking at least one class of antihypertensive medication, and 56 patients (80%) had intermittently high blood pressure. After surgery, the mean number of antihypertensive medication classes per patient was significantly reduced from 1.61±0.77 pre-procedure to 1.27±0.88 post-procedure (P??0.001). The blood pressure of 48 of the 56 cases (86%) with preoperative intermittent high blood pressure returned to normal post procedure. A total of 50 patients (71%) recorded improvements on the hypertension control scale, with the overall mean score decreasing from 3.1±1.0 pre-procedure to 1.4±1.0 post-procedure (P??0.001). Therefore, successful laparoscopic fundoplication may result in better blood pressure control in some hypertensive GERD patients. This result suggests a possible connection between gastroesophageal reflux and hypertension. Full text PDFCite this article: Zhiwei Hu,Meiping Chen,Jimin Wu,Qing Song,Chao Yan,Xing Du,Zhonggao Wang.

Frontiers of Medicine, 2017. 11(1): 68-73 Changes in lncRNAs and related genes in β-thalassemia minor and β-thalassemia major DOI: 10.1007/s11684-017-0503-1Jing Ma,Fei Liu,Xin Du,Duan Ma,Likuan XiongAbstract: β-thalassemia is caused by β-globin gene mutations. However, heterogeneous phenotypes were found in individuals with same genotype, and still undescribed mechanism underlies such variation. We collected blood samples from 30 β-thalassemia major, 30 β-thalassemia minor patients, and 30 matched normal controls. Human lncRNA Array v2.0 (8 × 60 K, Arraystar) was used to detect changes in long non-coding RNAs (lncRNAs) and mRNAs in three samples each from β-thalassemia major, β-thalassemia minor, and control groups. Compared with normal controls, 1424 and 2045 lncRNAs were up- and downregulated, respectively, in β-thalassemia major patients, whereas 623 and 349 lncRNAs were up- and downregulated, respectively, in β-thalassemia minor patients. Compared with β-thalassemia minor group, 1367 and 2356 lncRNAs were up- and downregulated, respectively, in β-thalassemia major group. We selected five lncRNAs that displayed altered expressions (DQ583499, X-inactive specific transcript (Xist), lincRNA-TPM1, MRFS16P, and lincRNA-RUNX2-2) and confirmed their expression levels in all samples using real-time polymerase chain reaction. Based on coding-non-coding gene co-expression network and gene ontology biological process analyses, several signaling pathways were associated with three common organ systems exhibiting β-thalassemia phenotypes: hematologic, skeletal, and hepatic systems. This study implicates that abnormal expression levels of lncRNAs and mRNA in β-thalassemia cases may be correlated with its various clinical phenotypes.

Frontiers of Medicine, 2017. 11(1): 74-86 Regulatory mechanism and functional analysis of S100A9 in acute promyelocytic leukemia cells DOI: 10.1007/s11684-016-0469-4Yonglan Zhu,Fang Zhang,Shanzhen Zhang,Wanglong Deng,Huiyong Fan,Haiwei Wang,Ji ZhangAbstract: S100A9, a calcium-binding protein, participates in the inflammatory process and development of various tumors, thus attracting much attention in the field of cancer biology. This study aimed to investigate the regulatory mechanism of S100A9 and its function involvement in APL. We used real-time quantitative PCR to determine whether PML/RARα affects the expression of S100A9 in NB4 and PR9 cells upon ATRA treatment. ChIP-based PCR and dual-luciferase reporter assay system were used to detect how PML/RARα and PU.1 regulate S100A9 promoter activity. CCK-8 assay and flow cytometry were employed to observe the viability and apoptosis of NB4 cells when S100A9 was overexpressed. Results showed that S100A9 was an ATRA-responsive gene, and PML/RARα was necessary for the ATRA-induced expression of S100A9 in APL cells. In addition, PU.1 could bind to the promoter of S100A9, especially when treated with ATRA in NB4 cells, and promote its activity. More importantly, overexpression of S100A9 induced the apoptosis of NB4 cells and inhibited cell growth. Collectively, our data indicated that PML/RARα and PU.1 were necessary for the ATRA-induced expression of S100A9 in APL cells. Furthermore, S100A9 promoted apoptosis in APL cells and affected cell growth. Full text PDFCite this article: Yonglan Zhu,Fang Zhang,Shanzhen Zhang,Wanglong Deng,Huiyong Fan,Haiwei Wang,Ji Zhang.

Frontiers of Medicine, 2017. 11(1): 87-96 iTRAQ-based quantitative proteomic analysis on differentially expressed proteins of rat mandibular condylar cartilage induced by reducing dietary loading DOI: 10.1007/s11684-016-0496-1Liting Jiang,Yinyin Xie,Li Wei,Qi Zhou,Ning Li,Xinquan Jiang,Yiming GaoAbstract: As muscle activity during growth is considerably important for mandible quality and morphology, reducing dietary loading directly influences the development and metabolic activity of mandibular condylar cartilage (MCC). However, an overall investigation of changes in the protein composition of MCC has not been fully described in literature. To study the protein expression and putative signaling in vivo, we evaluated the structural changes of MCC and differentially expressed proteins induced by reducing functional loading in rat MCC at developmental stages. Isobaric tag for relative and absolute quantitation-based 2D nano-high performance liquid chromatography (HPLC) and matrix-assisted laser desorption/ionization time-of-flight/ time-of-flight (MALDI-TOF/TOF) technologies were used. Global protein profiling, KEGG and PANTHER pathways, and functional categories were analyzed. Consequently, histological and tartrate-resistant acid phosphatase staining indicated the altered histological structure of condylar cartilage and increased bone remodeling activity in hard-diet group. A total of 805 differentially expressed proteins were then identified. GO analysis revealed a significant number of proteins involved in the metabolic process, cellular process, biological regulation, localization, developmental process, and response to stimulus. KEGG pathway analysis also suggested that these proteins participated in various signaling pathways, including calcium signaling pathway, gap junction, ErbB signaling pathway, and mitogen-activated protein kinase signaling pathway. Collagen types I and II were further validated by immunohistochemical staining and Western blot analysis. Taken together, the present study provides an insight into the molecular mechanism of regulating condylar growth and remodeling induced by reducing dietary loading at the protein level.

A total of 207 patients with type 2 diabetes and chronic periodontitis (CP) were divided according to tertiles of mean PISA (periodontal inflamed surface area) scores as low, middle and high PISA groups. Simultaneously a group of 67 periodontally healthy individuals (PH) was recruited. Periodontal examinations, including full-mouth assessment of probing depths (PPD), bleeding on probing, clinical attachment level and plaque scores were determined. Blood analyses were carried out for glycated hemoglobin (HbA1c), fasting plasma glucose (FPG), 2 h post parandial glucose (PPG). Individuals in PH group had significantly better glycemic control than CP group. Upon one-way analysis of variance, subjects with increased PISA had significantly higher HbA1c levels, retinopathy and nephropathy (P0.05). After controlling for age, gender, body mass index (BMI), socioeconomic status (SES), family history of diabetes and periodontitis, duration of diabetes, the mean PISA in mm2, PPD 4--6 mm (%) and PPD≥7 mm (%) emerged as significant predictors for elevated HbA1c in regression model (P0.05). Logistic regression analysis revealed that PISA was associated with higher risk of having retinopathy and neuropathy (odds ratio). In our study, the association between glycemic control and diabetic complications with periodontitis was observed.

Frontiers of Medicine, 2017. 11(1): 110-119 Cotransfecting norepinephrine transporter and vesicular monoamine transporter 2 genes for increased retention of metaiodobenzylguanidine labeled with iodine 131 in malignant hepatocarcinoma cells DOI: 10.1007/s11684-017-0501-3Yanlin Zhao,Xiao Zhong,Xiaohong Ou,Huawei Cai,Xiaoai Wu,Rui HuangAbstract: Norepinephrine transporter (NET) transfection leads to significant uptake of iodine-131-labeled metaiodobenzylguanidine (131I-MIBG) in non-neuroendocrine tumors. However, the use of 131I-MIBG is limited by its short retention time in target cells. To prolong the retention of 131I-MIBG in target cells, we infected hepatocarcinoma (HepG2) cells with Lentivirus-encoding human NET and vesicular monoamine transporter 2 (VMAT2) genes to obtain NET-expressing, NET-VMAT2-coexpressing, and negative-control cell lines. We evaluated the uptake and efflux of 131I-MIBG both in vitro and in vivo in mice bearing transfected tumors. NET-expressing and NET-VMAT2-coexpressing cells respectively showed 2.24 and 2.22 times higher 131I-MIBG uptake than controls. Two hours after removal of 131I-MIBG-containing medium, 25.4% efflux was observed in NET-VMAT2-coexpressing cells and 38.6% in NET-expressing cells. In vivo experiments were performed in nude mice bearing transfected tumors; results revealed that NET-VMAT2-coexpressing tumors had longer 131I-MIBG retention time than NET-expressing tumors. Meanwhile, NET-VMAT2-coexpressing and NET-expressing tumors displayed 0.54% and 0.19%, respectively, of the injected dose per gram of tissue 24 h after 131I-MIBG administration. Cotransfection of HepG2 cells with NET and VMAT2 resulted in increased 131I-MIBG uptake and retention. However, the degree of increase was insufficient to be therapeutically effective in target cells. Full text PDFCite this article: Yanlin Zhao,Xiao Zhong,Xiaohong Ou,Huawei Cai,Xiaoai Wu,Rui Huang.

Frontiers of Medicine, 2017. 11(1): 120-128 A comparative study of electroacupuncture at Zhongliao (BL33) and other acupoints for overactive bladder symptoms DOI: 10.1007/s11684-016-0491-6Likun Yang,Yang Wang,Qian Mo,Zhishun LiuAbstract: Electroacupuncture (EA) at Zhongliao (BL33) can improve the symptoms of overactive bladder (OAB), such as urinary frequency, urgency, and incontinence. However, its performance compared with other acupoints remains unclear. This study investigated the effects of EA at BL33 with deep needling on rats with OAB by detecting urodynamics in eight groups: no intervention group, D-BL33 group (deep needling at BL33), S-BL33 group (shallow needling at BL33), non-acupoint group (needling at the non-acupoint next to BL33), Weizhong (BL40) group, Sanyinjiao (SP6) group, Tongtian (BL7) group, and Hegu (LI4) group. Results revealed that EA at BL33 with deep needling, BL40, and SP6 prolonged the intercontraction interval (ICI) of rats with OAB (P=0.001, P=0.005, P=0.046, respectively, post-treatment vs. post-modeling). Furthermore, the change in ICI from post-modeling in the D-BL33 group was significantly greater than those of the no intervention and other EA groups (all P0.01). Significantly shortened vesical micturition time (VMT) and elevated maximum detrusor pressure (MDP) were also observed in the D-BL33 group (P=0.017 and P=0.024, respectively, post-treatment vs. post-modeling). However, no statistically significant differences in the changes of VMT and MDP from post-modeling were observed between D-BL33 and the other EA groups. In conclusion, EA at BL33 with deep needling may inhibit acetic-acid-induced OAB more effectively. Full text PDFCite this article: Likun Yang,Yang Wang,Qian Mo,Zhishun Liu.

Frontiers of Medicine, 2017. 11(1): 129-136 Effects of different doses of cadmium on secondary metabolites and gene expression in Artemisia annua L. DOI: 10.1007/s11684-016-0486-3Liangyun Zhou,Guang Yang,Haifeng Sun,Jinfu Tang,Jian Yang,Yizhan Wang,Thomas Avery Garran,Lanping GuoAbstract: This study aims to elucidate the underlying molecular mechanisms of artemisinin accumulation induced by cadmium (Cd). The effects of different Cd concentrations (0, 20, 60, and 120 μmol/L) on the biosynthesis of Artemisia annua L. were examined. Intermediate and end products were quantified by HPLC-ESI-MS/MS analysis. The expression of key biosynthesis enzymes was also determined by qRT-PCR. The results showed that the application of treatment with 60 and 120 μmol/L Cd for 3 days significantly improved the biosynthesis of artemisinic acid, arteannuin B, and artemisinin. The concentrations of artemisinic acid, arteannuin B, and artemisinin in the 120 μmol/L Cd-treated group were 2.26, 102.08, and 33.63 times higher than those in the control group, respectively. The concentrations of arteannuin B and artemisinin in 60 μmol/L Cd-treated leaves were 61.10 and 26.40 times higher than those in the control group, respectively. The relative expression levels of HMGR, FPS, ADS, CYP71AV1, DBR2, ALDH1, and DXR were up-regulated in the 120 μmol/L Cd-treated group because of increased contents of artemisinic metabolites after 3 days of treatment. Hence, appropriate doses of Cd can increase the concentrations of artemisinic metabolites at a certain time point by up-regulating the relative expression levels of key enzyme genes involved in artemisinin biosynthesis.

This study aims to investigate the mental health status of nurses exposed to blood through needlestick injuries. A total of 302 nurses working in the hospital of Guangdong, China, participated in this study. Out of the 302 nurses, 140 did not experience any needlestick injuries during the previous week, whereas 162 nurses experienced needlestick injuries. The General Health Questionnaire (GHQ)-28 Standardized Questionnaire, which uses physical, anxiety, social function, and depression subscales, was used in this study. No significant difference between nurses exposed to blood and nurses not exposed to blood was found in terms of gender, age, length of employment, and civil status (P0.05). Results from the GHQ-28 Standardized Questionnaire showed that 75.9% (123/162) of nurses exposed to blood were suspected to suffer from mental disorders, whereas 40% (56/140) of nurses not exposed to blood were suspected to suffer from mental disorders. The mean mental health scores of nurses exposed to blood and those not exposed were 8.73±7.32 and 5.69±5.70, respectively. From these results, we can conclude that blood exposure from needlestick injuries leads to higher prevalence of depression, anxiety, and stress symptoms in nurses. This finding highlights the importance of providing efficient, adequate, and appropriate support services after nurses are exposed to blood from needlestick injuries.

In the meantime, the development of medicine is facing challenges that resulted from the over-division and specialization of disciplines and the fragmentation of medical knowledge. To construct a new medical system that is more suitable for human health and disease treatment, holistic integrative medicine (HIM), which regards the human body as a holistic entity, organically integrates the most advanced knowledge and theories in each medical field and the most effective practices in various clinical specialties to revise and adjust on the basis of social, environmental, and psychological conditions. HIM is the inevitable and necessary direction for the future development of medicine. In this article, we illustrated the connotation of HIM, the differences between HIM and other medical conceptions, and the practice of HIM in recent years.

人类癌症治疗新希望:急性早幼粒细胞白血病的协同靶向治疗
WileyChina 2015-9-16 11:56
白血病是血液系统的恶性肿瘤,在40岁以下男性和20岁以下女性中,死亡率在所有恶性肿瘤中居首。而急性早幼粒细胞白血病(APL)曾是白血病中最凶险的一种。由 上海交通大学医学院附属瑞金医院上海血液学研究所所长陈赛娟院士主持的项目 “髓系白血病发病机制和新型靶向治疗研究”就APL的提出了新的治疗方案,该研究发现 全反式维甲酸(ATRA)或三氧化二砷(ATO)单独使用时对带有PML-RARα融合基因的APL患者有治疗效果,且两种药物的组合可以协同作用 ,可 大大提高了APL的治愈率。 近期, 陈赛娟院士、陈竺院士及其团队 将一篇关于 急性早幼粒细胞白血病的协同靶向治疗:人类癌症转化研究模型 ( Synergistic targetedtherapy for acute promyelocytic leukaemia: a model of translational research inhuman cancer ) 的综述文章发表在 Journal of Internal Medicine 。这篇review文章系统的阐述了急性早幼粒细胞白血病的协同靶向治疗的机理,对广大血液病研究人员及医疗工作者有广泛参考价值,特在此与大家分享。 原文链接: http://onlinelibrary.wiley.com/enhanced/doi/10.1111/joim.12376/ 急性早幼粒细胞白血病的协同靶向治疗:人类癌症转化研究模型 ( J.-Q. Mi, S.-J. Chen, G.-B. Zhou, X.-J. Yan, Z. Chen ) 摘要 急性早幼粒细胞白血病( APL),急性髓性白血病的M3亚型,曾经是一种致命的疾病, 但当前多数 APL患者可以通过分子靶向疗法成功治愈 。这类疾病的存活率的大幅戏剧性的提升是现代医学的优势的一个范例。 APL的特征在于一个均衡相互染色体易位,将17号染色体上的的视黄酸受体α基因(RARα)熔合至15号染色体上急性早幼粒细胞白血病(PML)基因。我们已经发现 全反式维甲酸( ATRA)或三氧化二砷(ATO)单独使用时对带有PML-RARα融合基因的APL患者有治疗效果,且两种药物的组合可以协同作用,进一步提高患者的治愈率 。在这里,我们提供了一种APL发病机理以及ATRA和ATO的各自角色背后机制的自知力。不仅如此,导致包括白血病起始细胞在内的APL细胞更有效的分化和死亡的治疗方法以及更彻底根除疾病的方法将被讨论。此外,作为转化性研究的典范, APL治愈疗法的发展一直遵循'试验台到病床'和'病床到试验台的双向方法,它可以作为一个有价值的范例用于其他恶性肿瘤的诊断和治疗。 引论 白血病是儿童和年轻成人( 40岁以下)癌症死亡的最常见的原因之一,并包括一组血液学恶性肿瘤,它根据所涉及的谱系可以分为髓性或淋巴白血病,根据疾病病程可以分为急性或慢性白血病。急性早幼粒细胞白血病(APL),也被称为急性髓性白血病的M3亚型(AML-M3),占所有AML病例的10%,并且具有非常严重的自然过程。APL最先由瑞典血液学学者Hillestad 描述,他认为是APL是急性白血病中最恶性的形式,由于白血病急性病变的沉重负担,其中髓样分化被阻止在早幼粒细胞的阶段,并伴有出血综合征。尽管化疗能在75-80%的患者中达到完全缓解(CR),缓解期中位数为11〜25个月不等且5年无病生存率(DFS)仅为35%至45%;化疗通常会加剧出血,在缓解 的诱导过程中导致过早死亡。重要的是,今天这种曾经致命的疾病的绝大多数患是可以治愈的。回首本病的治疗历史,我们发现,它代表了转化型研究在人类癌症的一个新的范例,其中不仅有已经富有成效地证明“从实验室到病床'和'病床到实验室”的双向方法,而且有由两种试剂联合使用的关键癌蛋白的协同定位,全反式维甲酸(ATRA)和三氧化二砷(ATO),而不是单一疗法,这些给予我们致治愈APL患者的能力。 急性早幼粒细胞白 血病的发病机制示意图 结论 全反式维甲酸和三氧化二砷的引入使 APL患者可以通过靶向治疗治愈 。当这些药物结合使用时,其协同作用可大大提高大多数但并非所有的患者的治愈机会。这种新的模式越过以往常规化疗的想法,将疗法的早期模型带入协同靶向治疗的新领域。这个概念也应适用于其它类型的肿瘤的治疗。但是, 10-15%的APL患者,大多为高风险的病人,都没有被治愈。对于这些人,我们将测试包括传统的化疗或免疫治疗的综合疗法。我们认为,随着在精密医学背景下转移性研究的逐步发展,其他类型的AML的治愈率也将大幅增加。

我所了解的三氧化二砷注射液开发过程
热度 9 jinwsapa 2011-8-27 12:47
看了最近饶毅教授写的有关中药砒霜和青蒿素的开发过程, 读来倍感亲切和熟悉. 因为自己曾经对三氧化二砷治疗急性早粒白血病的发现和开发曾作过长达一年的调研. 有点了解和发言权, 特意在此与大家分享.并对饶毅教授的文章作相应补充. 1998年至2001年间, 笔者先后走访哈医大一院十余次,调研访问了许多与三氧化二砷开发有关的医生, 还拜访了长期生存的患者, 对三氧化二砷的开发有了比较全面的了解, 根据我调研和回忆结果,总的印象和背景大致是: 1) 这是一个偶然的发现, 并通过二度开发做成的项目, 最初是在70年代早期, 因为626下乡送医, 哈医大一院医生在巡回医疗中发现被医院判"死刑" 而放弃治疗的癌症患者居然大难不死,了解真相后,方知有民间偏方治疗, 居然控制住病情, 让晚期癌症患者得以生存,并生活自理.于是带着惊喜和好奇,拿回偏方回院里分析, 终于发现"以毒攻毒" 妙方的奥秘. 2) 这是集体智慧和协作的结晶: 药方主要由是韩太云药师配制的, 研制分析过程中, 有病理, 药理, 药剂, 中医, 血液病方面的专家参与, 共同研制, 光从论文和报道署名看, 就会知道这里有许多人的参与. 张亭栋是其中主要一员, 但评功论奖, 并非绝对的第一功臣. 尽管专利是以他一人名义申报的. 3)偏方的组分分拆后所做的药理试验,研制成癌灵一号,癌灵二号和癌灵三号等药物, 有效成分主要是三种,***,氯化汞,和蟾蜍粉。癌灵一号在临床上被证明是最有效的。在临床上所做的适应症,开始比较杂,直到积累足够病例和细胞遗传学分型后,才逐渐知道APL- 急性早粒白血病是最有效的适应症,其他CML,MDS和MM也有效,那是后来的事,但效果远不如APL。这里病理诊断的医生功不可抹。 4) 制剂由最初的拴剂改成肌注, 再改成后来的静脉注射, 是一个逐步改型的过程, 以韩太云药师为首的医院制剂室为此立下汗马功劳. 可惜韩去世太早, 不然大部分功劳要算在他头上. 另一个惊喜是,中西医治疗过程中的偶然发现,最初注射量很低,对有的患者起效不显著. 一位儿童治疗不见好转, 医生配制了足够量的药送患儿回乡. 结果当地赤脚医生把3-5天的剂量按一天剂量注射, 结果歪打正着, 奇迹般地救活了该患儿,从此医生们知道有效安全剂量其实可以更高. Such A Powerful PK Study! 5) 大约在80年代末或90年代初,医院制剂室由于临时缺货,在注射液中没有加入氯化汞,(轻粉)也有一说法是,该原料较难溶,故意忽略不加。 有几批制剂做出来的临床试用后,发现效果不便,副作用还减少。从此该制剂成了单一As2O3有效成分的西药注射液。 6)张亭栋医生所率领的中西医科室,在70-80年代治疗病人时,主要用癌灵一号,外以中药辅助治疗,而且案例不是非常统一,按GCP的原则,有严格的入选标准和治疗方案。但他们小组的前期研究的确在后来更规范的血液科系统研究中起了很好示范引导作用。血液科主任张鹏医生所领导的小组,在90年代初,系统地对100多位APL患者进行诊断和单一药物的治疗,结果发现80%以上患者经过30-45天注射后获得完全缓解(甚至分子水平上的缓解,这里有上海瑞金医院的帮助)所以95-96年在中华血液病杂志所发表的论文,是第一篇最接近规范化临床试验所取得的很有说服力的单药治疗及随访结果临床论文。 7)王振义教授所领导的瑞金医院研究小组,80年代发明了用维甲酸分化诱导治疗APL,取得国际瞩目的研究成果。让90%以上的患者获得CR,完全缓解,但在临床中发现,CR患者会有复发,长期服药还有RA综合症,或抗药性。到了这步,病人就无药可救,只能等死。当瑞金医院知道哈医大一院的成果后,分别邀请张亭栋和张鹏前往上海交流并开展合作,(据张鹏医生透露,不知何因,瑞金医院与他的合作灭有进行下去,瑞金只选择与张亭栋合作) 临床数据显示RA治疗无效或难治型APL用As2O3注射后,明显有效。瑞金医院和血液所接下来做了好多机理研究和人体PK研究,并用英文发表了重要的论文,从此中国医生的这一成果,从中国走向世界。 8)当国外同行通过国际会议和论文了解到这一成果后,引起极大的兴趣。因为王振义教授在RA分化诱导治疗的成就和地位,As2O3 治疗APL的临床论文在美国发表后,立刻吸引国外医药界和投资界的关注。由于APL适应症的患者数很少,大药厂无心对这一孤儿药进行代价昂贵的开发,国内药企也没有魄力购买这一具有世界水平的临床研究成果,所以这一药物最终还是以哈医大一院自己组建的药厂伊达药业名义报批研制和产业化。现在已经转移给双鹭药业接手。 9)笔者97年加入派拉蒙投资公司后不久,就接手三氧化二砷项目的开发,先后到中国10余趟,走访了当年开发这一药物的主要参与者,其中包括张亭栋医生,张鹏主任,金镇敬(病理)孙弘德(中医)胡晓晨等医生, 还有一位做了多例儿童APL治疗的医生。韩太云药师因为过早去世,没有碰面过. 但他的贡献得到多数人肯定. 通过上述走访, 看过一些骨髓片和病历, 大致了解了这一药物开发的历史过程和里程碑,深感这一成果来自不宜,很难用单一人士的科研和创造力能独立完成。即使到90年代以后,消息传开,有瑞金医院加盟合作,尤其有陈国强,陈赛娟,王振义,陈竺等重磅人物参与研究,使得这一成果更加完善和具有可看性及推广价值。 10)在这一成果的归属上,一直在哈医一院内部有很大争议。专利是以张庭栋作为发明人,但参与者有许多重要贡献者和设计者,所以严格意义上讲,把功劳和发现归于一人,并不合理。据说二张的专利权属纠纷一直闹到国家专利局和黑龙江省政府,至今或许都没有彻底解决。另外尽管这一专利早在1995年就已申请,并随后授权,但专利权利太窄,基本没有保护力度,所以国外接连申请了多项专利,制剂专利和给药方式(血药浓度范围(如如何达到Cmax)可以在不侵权的条件下,作出更好的制剂,这样的结局主要是国内缺乏专利保护意识和经验,70-80年代就大量披露试验结果所致,不能不说是一大遗憾。, 11)正因为这一职务发明,内部纠纷根深蒂固,对外合作进展缓慢,让国外机构占了大便宜。Waxman基金会几乎不花什么代价就拿走了国外的开发权。帮助在美国申请了专利,在经历多年没能拿到专利,也没有取得任何临床研发进展的情况下,找到派拉蒙投资公司,此时后者已经投资500万美元以上,开发有自己特有配方和工艺的Trisenox制剂,做完一期临床 并在新英格兰医学杂志发表,处于十分被动的Waxman 基金会没有太多的谈判筹码,只能接受投资方设置的合作条件。最后改药中国专利在美国的申请经过三次Rejection之后,终于在美方投资者高价聘请的律师帮助下,获得了有限的保护,并归PoLaRx Biopharmaceutical在海外独家使用。 12)这个项目在海外的成功虚拟化运作和顺利退出,不在这里详述。但有一点可以说,中国人在APL治疗的创新研发和治疗手段的首创方面,创下了全球最有声望的贡献,APL最有效的治疗均为中国医生所发明。挽救了成千上万名APL患者的生命。至今罗氏和泰瓦分别在销售ATRA和Trisenox 药物,泰瓦今年60多亿美元收购Cephalon药业,后者从CellTherapeutic 公司手里买下Trisenox,最赚钱的是Paramount Capital, 只花了1000多万美元,在三年时间内, 就基本完成了三期临床试验,创下FDA批准新药历史上最快的纪录。赚了超过50倍的ROI, 这里当然有哈尔滨医科大学第一附属医院的巨大贡献和医生的集体智慧,在美国一期临床期间,美国医生通过越洋电话得到中国医生的详细指导,使得临床实验进行非常顺利,FDA高度重视和赞赏中美医生临床合作,也为此项目开下先河,在没有递交任何详细临床资料和GMP原料的情况下,就放行让我们快速启动一期临床。新英格兰医学杂志最快速度发表了临床论文,并加了高度评价的专家编辑评论。

一个遗落的原始创新思想的再思考
热度 2 lxchencn 2011-6-5 18:04
最近温家宝总理在中国科协会议上特别强调原始创新的重要性,这再次让我想起了一个自己的“原始创新”的思想,虽然这个创新思路已经过去20多年,但还是让我难以忘怀。 还是1988年在一个落后地区县医院当医生的时候,当时感觉总有不少白血病的病人,而且是年轻的患者,发病急,进展快,几乎没有救活的,病史上常常有去南方化工厂、电子厂、油漆厂等打工的历史,治疗方法就是教材推荐的激素加化疗,面对那些如花的青年逝去,作为医生多想把他们救活,但是束手无策,为了寻求良方,常常去医院的图书室查看书籍和杂志,甚至还看看看不懂的外文杂志,虽然这些杂志就一直没有人看过,记得看到过著名血液病专家郁知非的专著,当然当时还不知道他的名气有如此巨大,直到很多年以后到广州读博士才知道郁知非教授的在血液病界的威名,这已经是后话了。当时苦苦思索,有一天突然想起胚胎发育过程中开始并没有造血的,直到某一个时期才开始造血,刺激造血的物质一定在胎儿的血液里面,如果把胎儿或婴幼儿的血液输注白血病人,里面含有的刺激造血的因子有可能也能刺激白血病病人重新造血,也许可以治疗白血病。这个大胆新颖的想法让我挥之不去,想试试能否有效,当时在县级医院也没有什么科研实验条件,更没有什么做研究的想法,只是出于治病救人的简单出发点,当然也没有想清楚如何去查阅文献询问专家之类的事情。再想想,抽胎儿或婴幼儿的血液来输给病人根本不现实,再一想,生小孩的时候脐带、胎盘里面有一些血,如果能够收集起来,多输几个脐带的血也许是可行的。说干就干,死马当成活马医,反正医不好是死,试试也许能够生。与妇产科联系,与消毒室联系拿消毒瓶,产房医生帮忙,生小孩剪脐带后用瓶子接一些脐带血,也把胎盘挤压一下可以收集更多血液,做好血型配型,然后准备输血,问题来了,生产是带细菌的,收集的血液是否是无菌呢?医院没有培养检验细菌条件,无法确定血液是否无菌,尽管收集的很多瓶脐带血也不敢给病人用,如果感染了,病人死了,责任可承担不起呀。这个“原创思想”就这样遗落了。后来考研究生走了,再读博士,做点科研,重新想起了当年比较幼稚的想法,恍然醒悟,原来就是脐带干细胞的想法,当然,已经是太久的故事了。 回想当年的想法,想想现在的科研,如何找到原始创新的思想?如何实现原始创新?真不是一件容易的事,走原始创新的道路,任重道远!
