OBJECTIVE:To study the general pattern and characteristics of the adverse drug reactions(ADRs) induced by Zhongjiefeng injection for reference of rational drug use.METHODS:A total of 25 ADRs cases induced by Zhongjiefeng injection reported in domestic medical journals during 1994～2007 were analyzed statistically.RESULTS:ADRs of Zhongjiefeng injection were more often seen in children and occurred usually within 30 min after injection,appeared mainly as allergic rcactions (88.0%) or anaphylactic shock in severe cases.CONCLUSION:Clinical physicians and pharmacists should stay on high alert to the ADRs induced by Zhongjiefeng injection and adhere to rational drug use.

Objective:To establish a rapid and sensitive method for the determination of carbendazim in honeysuckle flowers by LC-MS/MS. Methods:The sample was extracted by acetic ether. The mass spectrometer was operated in the positive ionization elec-trospray ( ESI) mode using selection ion monitoring ( SIM) . The transition m/z 192→160 was used to quantify carbendazim. Results:The method had a satisfactory linearity within the range of 50-5 000 ng·ml-1 for carbendazim (r=0. 999 4), the limit of detection (LOD) was 2. 0 ng·ml-1, and the mean recovery was 93. 2%. Conclusion:The method of LC-MS/MS is sensitive, simple and ac-curate,which is proved to be suitable for the determination of carbendazim in honeysuckle flowers.

Objective To evaluate the effectiveness of Tanreqing Injection for the preventive of radiation pneumonitis. Methods Retrieving literatures in CNKI, CBM,VIP and WanFang, Medline, Google Scholar database from January 2000 to July 2013.Two researchers extracted and evaluated the quality of all the data independently.RevMan 5.2 software was used for statistical analysis. Results 11 papers and 939 patients were involved in the study. Meta analysis showed statistical difference for the index of marked efficacy between Tanreqing group and radiation group with OR(95%CI)is 0.42(0.30, 0.57). Significant difference was found for the index of more than Grade 3 of radiation pneumonitis, radiation pulmonary fibrosis with OR(95% CI) 0.19(0.11, 0.35), 0.35(0.23, 0.53), respectively(P=0.65). Statistical difference was observed for the index of the dose of radiation and the average onset time of radiation pneumonitis with OR(95%CI) 7.39(4.41, 10.38) and 7.72(6.84, 8.61) respectively. Conclusion Meta analysis based on current limited clinical research results preliminary shows that. Tanreqing injection has a good clinical efficacy for the preventive effect of radiation pneumonitis. The use of Tanreqing injection could reduce the rate of more than Grade 3 of radiation pneumonitis as well as radiation pulmonary fibrosis, extend the onset time and increase the dose which leads to radiation pneumonitis.

Objective To evaluate the efficacy of aerosol inhalation ofXiyanpingversus ribavirin for the treatment of respiratory tract infections in children.MethodsPubMed, Embase, Cochrane database of Systematic Reviews, CNKI, cqvip and wanfangdata were searched. The randomized controlled trials(RCTs) of aerosol inhalation ofXiyanpingversus ribavirin injections for the treatment of respiratory tract infections in children were incuded. The quality of trials was evaluated and data analyses were performed with the Cochrane Collaboration’s software RevMan 5.0.Results A total of 7 trials were included, involving 857 patients(437 treated withXiyanping, 420 treated with ribavirin). Both of the clinical cure rate(50.11%vs. 40.71%) and clinical effective rate(91.08%vs. 75.95%) in theXiyanping group were significantly higher than those in the ribavirin group, withOR(95%CI) 1.49(1.13 to 1.97) and 3.54(1.87 to 6.71), respectively.Conclusions Aerosol inhalation ofXiyanping superior to aerosol inhalation of ribavirin for the treatment of respiratory tract infections in children. Owing to the poor quality and the small sample size of included trials, more larger good quality CRTs are required to confirm this conclusion.

Objective To compare the feasibility and safety of endoscopy with laparoscopy and without for gastric stromal tumor.Methods A retrospective and comprehensive analysis was made based on the clinical data of endoscopic (53 cases) and laparoscopic (39 cases) resection for gastric stromal tumor (diameter ＜ 3 cm with clear boundary),by comparing the operation time,intraoperative blood loss,indwelling time of postoperative gastric tube,recovery time of bowel functions,postoperative complications,hospitalization time,metastasis,recurrence rate.Results Compared with the laparoscopic group,the endoscopic group required shorter operation time [50(48-58) min VS 70 (50-95) min,U =1575.00,P ＜ 0.01],less intraoperative blood loss [10 (5-15) ml VS 20 (20-30) ml,U =1794.00,P ＜ 0.01],earlier recovery of bowel functions [18 (8-36) h VS 24 (20-40) h,U =1666.00,P ＜ 0.01],hospitalization time,indwelling time of the postoperative gastric tube and postoperative complications showed no statistical difference (P ＞ 0.05).The postoperative follow-up time were (27 + 15) and (24 + 11) months in the endoscopic and laparoscopic group,respectively (t =0.3084,P ＞ 0.05).During the follow-up,no tumor recurrence or distant metastasis was discovered,nor was death of gastric stromal tumor.Conclusion Endoscopy without the assist of laparoscopy for the gastric stromal tumor,whose diameter is less than 3 cm with clear boundary,is safe and less invasive,and leads to quick recovery.

OBJECTIVE:To systematically review the efficacy and safety of the aerosol inhalation of Yanhuning for injection in adjuvant treatment of children respiratory system infections,and provide evidence-based basis for the administration way of off-label drug use in clinic. METHODS:Retrieved from PubMed,Science direct,EMBase,CHKD,VIP and Wanfang Database, randomized controlled trials(RCT)or quasi-randomized controlled trials(qRCT)about the aerosol inhalation of Yanhuning for in-jection in adjuvant treatment of children respiratory system infections were collected. Meta-analysis was performed by using Rev Man 5.3 software after data extraction and quality evaluation. RESULTS:Totally 11 RCTs were enrolled,involving 982 patients. Results of Meta-analysis showed,the aerosol inhalation of Yanhuning for injection in adjuvant treatment of children respiratory sys-tem infections can significantly improve the clinical total effective rate [OR=4.47,95%CI(2.80,7.16),P<0.001],shorten breath shortness duration [MD=-2.05,95%CI(-2.86,-1.24),P<0.001],cough duration [MD=-1.73,95%CI(-2.34,-1.13),P<0.001] and pulmonary rales duration [MD=-2.13,95%CI(-3.38,-0.89),P<0.001],reduce the hospitalization days [MD=-2.38, 95%CI(-2.86,-1.89),P<0.001],and not increase the incidence of adverse reactions [OR=0.65,95%CI(0.21,2.00),P=0.45], nor shorten the fever duration[MD=-1.18,95%CI(-2.58,0.22),P=0.10]. CONCLUSIONS:The aerosol inhalation of Yanhun-ing for injection can improve the clinical efficacy in adjuvant treatment of children respiratory system infection,it helps to improve respiratory symptoms in children and does not increase the incidence of adverse reactions.

This article reviews the related literature on the reversal of multi-drug resistance in tumors by cepharanthine, and summarizes the reversal effects and mechanisms of multi-drug resistance in different tumors such as leukemia, liver cancer, ovarian cancer, breast cancer, esophageal cancer and colon cancer. Its reversal effect on multi-drug resistance of tumors is the result of a multi-channel, multi-link combination. The main mechanism is to inhibit membrane transporter function, affect enzyme transfer system, inhibit anti-apoptotic pathway activation and anti-apoptotic protein expression.

Thromboxane A2 receptors (TPs) widely distribute in different organ systems and localize both on cell membranes and in intracellular structures.TPs are the members of seven-transmembrane G-protein-coupled receptor (GPCR) super family.Historical-ly, the involvement of TPs in platelet functions has received the greatest attention .TPs have the capacity to activate different signaling cascades which regulate platelet shape change , aggregation and secretion response .Currently , anti-platelet drugs primarily act on re-ceptors and /or signaling molecules in activation pathways .The signaling transduction of TPs in platelet contributes to the investigation of the effects of extracts of traditional Chinese medicine on antiplatelet aggregation and the exploration of the action mechanisms .
