Traditional Chinese medicine(TCM)compatibility is related to the safety of clinical use of drugs and embodies the essence of interactions between drugs and organisms. This is a scientific problem thatr has attracted more attention. Currently, most of the knowledge on TCM compatibility is from predecessors′ experience. The corresponding molecular biology mechanism is poorly understood. As a powerful tool to identify a large number of proteins simultaneously,proteomics technology has the potential to reveal the protein alterations under certain conditions,and to provide more direct insights into biological processes during TCM compatibility. In this paper,we introduced the main technology of proteomics,including two dimensional gel electrophoresis,2D-DIGE,iTRAQ, QconCAT/MRM and chemical proteomics. Also,the applications of these technologies in the field of TCMM compatibility study were reviewed.

Objective To explore the status and influencing factors of posttraumatic growth (PTG) in breast cancer patients and identify the influence of cognitive appraisal on PTG and the relationship between PTG and cognitive appraisal. Methods A cross-sectional study was conducted. Totally 356 breast cancer patients were investigated with the revised Posttraumatic Growth Inventory (PTGI), the Cognitive Appraisal Scale. Results The average score of PTG in breast cancer patients was (55.06±14.36) points. There were significant differences between different education level and health-care payment patients in the total score of PTG (t=5.886, 5.154, P<0.01). The level of PTG was correlated with the patients′ cognitive appraisal way. It was negatively correlated with uncertain appraisal about disease and threat appraisal,and positively correlated with positive appraisal and responsible appraisal. The main prediction factors for PTG were positive appraisal, uncertain appraisal about disease, responsible appraisal, health-care payment and education level. All the variables could explain 42.7% variance of PTG. Conclusions Breast cancer patients in this study report moderate level of posttraumatic growth. The level of PTG in breast cancers is influenced by variables of patients′ education level, health-care payment and cognitive appraisal. Cognitive appraisal could predict the development of PTG significantly.

Though there is a great progress in research of medical ethics in China, a gap still remains between China and the developed countries now. Medical ethics committees are established one after another in many hospitals, but the level of standardization construction and ethical review level differ in thousands ways. The construction of ethical review platform on TCM can standardize the construction and investigation procedure, and can further enhance the ethical review level of medical ethics committee. Among them, institutional improvement of regulations and procedures can be acquired in short time, but the enhancement of ethical review level needs a long way to go. This article aimed to probe the thinking and methods on the enhancement of ethical review level through the practice and experience of the construction of TCM ethical review platform.

Objective To observe the effect of neoadjuvant chemotherapy combined with tumor cells reduction and postoperative intraperitoneal perfusion chemotherapy on the efficacy and quality of life of ovarian cancer.Methods From October 2010 to October 2013 at the Department of gynecology,Taizhou Municipal Hospital,65 cases of ovarian cancer patients for the treatment of stage Ⅲ and Ⅳ were randomly divided into intervention group (n =32) and control group (n =33).Patients in the intervention group received neoadjuvant chemotherapy after tumor cell reduction cytoreductive surgery and received postoperative intraperitoneal hyperthermic perfusion chemotherapy and conventional surgery after chemotherapy.Patients in the control group received conventional tumor cell cytoreductive surgery plus postoperative chemotherapy.Surgical status,the effectiveness of treatment,and adverse reactions were compared between two groups.Moreover,survival quality score,relapse rate,and mortality differences were compared between two groups.Results For the intervention group,operation status and effective treatment were better than the control group.The proportion of adverse reactions had no significant difference between two groups.Survival quality had no statistically significant difference between before treatment and after receiving treatment.Quality of life in the intervention group was better than that of the control group.Relapse rate,and mortality rate in the intervention group was lower than the control group.Conclusions Accepted neoadjuvant chemotherapy combined with tumor cytoreductive surgery and surgery after intraperitoneal hyperthermic perfusion chemotherapy can improve the effectiveness of treatment of ovarian cancers,and improve the quality of life,with better short-term effect.

Objective To investigate the genotypes of extended spectrum β-lactamases (ESBLs) and their carrying modes in Escherichia coli (E.coli) isolates,and to analyze the mechanism of protein phosphorylation and ESBLs gene expression induced by β-lactam antibiotics or inhibited by histidine kinase inhibitors.Methods The predominant genotypes of ESBLs (KPC,TEM,SHV and CTX-M) and their carrying modes were identified by PCR and sequencing analysis.E-test and micro-tube dilution method were applied to measure minimal inhibitory concentrations (MICs) and minimum bactericidal concentrations (MBCs).Immobilized metal ion affinity chromatography,bacterial protein phosphorylation detection kit and real-time fluorescent quantitation RT-PCR were performed to analyze the enhancing effects of 1/4 MIC penicillin or cefotaxime or the inhibitory effects of histidine kinase inhibitors (closantel,bromized or iodized methylimidazol) on protein phosphorylation and the expression of ESBLs at mRNA level in E.coli isolates.Results In 183 β-lactam antibiotics-resistant E.coli isolates,TEM and CTX-M genes (83.1％ and 77.1％) were highly expressed than other two ESBLs genes with a prevalent carrying mode of coexisting (65.0％) (P＜0.05).Penicillin or cefotaxime at 1/4 MIC induced the protein phosphorylation and promoted the expression of TEM,SHV and CTX-M at mRNA level (P＜0.05).Closantel (200 μmol),bromized methylimidazol (2 or 10 μmol) or iodized methylimidazol (20 or 50 μmol) could neither kill E.coli isolates nor inhibit their growth,but could inhibit the protein phosphorylation induced by above mentioned antibiotics and enhance the expression of ESBLs at mRNA level (P＜0.05).Moreover,the susceptibility of antibioticresistant E.coli strains to penicillin and cefotaxime were increased (P＜0.05).Conclusion TEM and CTX-M were the predominant genotypes of ESBLs carried by β-lactam antibiotics-resistant E.coli strains isolated from Zhejiang province,which were mostly found in a TEM plus CTX-M carrying mode.Sublethal dose of β-lactam antibiotics could up-regulate the expression of ESBLs genes in E.coli isolates via TCSS,but it could be inhibited by histidine kinase inhibitors.
