AIM:To study the protective effects of extract from Tribulus terrestris L on adriamycin-induced damage to myocardial mitochondria in rats. METHODS: Rats were given intraperitoneal injection of adriamycin (ADR) to induce the damage to myocardial mitochondria. After continuous ig of extract from Tribulus terrestris L, the every experimental group was observed myocardial ultrastructure with electron microscope, the mitochondrial membrane potential (MMP) and the activity of glutathione peroxidase (GSH-Px) ill myocardial mitochondria were determined. RESULTS: ADR of 20 mg/kg was given to rats intermittently induced severe damage to myocardial mitochondria in rats, decreased MMP and the activity of GSH-Px. Extract from Tribulus terrestris L middle- and high-dosage groups (30 mg/kg, 45 mg/kg) could reduce cardiotoxicity of ADR at the ultrastructure level, and increase MMP and the activity of GSH-Px. CONCLUSION: Extract from Tribulus terrestris L may decreased the damage to myocardial mitochondria induced by adriamycin, and has a protective effect on adriamycin-induced cardiotoxicity.

OBJECTIVETo study the effects of different doses of taurine (Tau) on calcium ion concentration ([Ca2+]i) and ATPase on cardiocyte membrane of diastole heart failure rats.

METHODDiastole heart failure model was established by the coarctation of abdominal aorta. Four weeks after operation, forty diastole heart failure rats were divided into four groups randomly as follows, model (normal saline 2 mL), taurine (400 mg x kg(-1) x d(-1)), taurine (200 mg x kg(-1) x d(-1)), taurine (100 mgx kg(-1) x d(-1)), with 10 rats for each group (n=10), and 10 sham operation rats was taken as control(normal saline, 2 mL). After 4 weeks administration, Isolate single cardiocyte by enzymatic isolation method which were loaded with Ca2+-sensitive fluorescent indicator Fluo-3/AM. [Ca2+]i was measured by laser scanning confocal microscope [LSCM], and represented it by fluorescent intensity [FI]; ATPase activity of cell membrane was measured by the method of enzymatic reaction chromatometry.

RESULTCompared with the control group, [Ca2+]i in cardiocyte increased markedly and the ATPase activity of cardiocyte membrane decreased significantly in the model group. Compared with the model group, fluorescent value decreased and ATPase activity increased significantly in Tau high-dose group; fluorescence value and ATPase activity decreased significantly in Tau mid-dose group; fluorescent value decreased and ATPase activity increased significantly in Tau low-dose group.

CONCLUSIONLarge dosage of Tau can increase ATPase activity on cardiocyte membrane, improve [Ca2+]i in cardiocyte and antagonise calcium overload of DHF rats.

Objective To investigate the effect of choledochoscopic gallbladder-preserving cholecystolithotomy combined with traditional Chinese medicine treatment.Methods A randomized controlled clinical study was conducted to analyze the 91 patients who were treated with choledochoscopic gallbladder-preserving cholecystolithotomy and 92 patients who underwent the same operation combined with subsequent treatment of traditional Chinese medicine.Intraoperative,postoperative and follow-up data were compared between the 2 groups (including operation time,blood loss,the rate of biliary fistula and common bile duct injury during the operation,gallbladder contraction function,the recurrence rate of gallstone,etc).Results In the simple choledochoscopic gallbladder-preserving cholecystolithotomy group,rate of gallstone recurrence was 7.7％ (7/91),the gallbladder wall was (3.5 ±0.6) mm,the gallbladder contraction function was (34.0 ± 3.6)％.However,the comprehensive treatment group,the rate of gallstone recurrence was 1.1％ (1/92),the gallbladder wall was(2.5 ±0.5) mm,the gallbladder contraction function was(48.0 ±4.5)％.There were significant differences between the two groups respectively (P ＜ 0.01,respectively).Conclusion Choledochoscopic gallbladder-preserving cholecystolithotomy combined with traditional Chinese medicine treatment is a safe,feasible,and minimal invasive approach for gallstone,and it can be considered as a alternative treatment of gallstone.

Objective To find out the general features ,drug type ,route of administration DID clinical mani-festation,outcome and so on in DID patients .Methods The statements of drug-induced diseases caused by traditional Chinese medicine and its preparation were collected ( the data provided by Adverse Drug Reaction Monitoring Center of Dongying City ) from 2004 to 2012 in Dongying area ,which would be reviewed and analyzed .Results 3 446 drug-induced disease cases of traditional Chinese medicine preparations were screened out .From 3 446 DID reports in which 603 kinds were involved ,599 kinds of traditional Chinese medicine and 4 kinds of Chinese herbal medicine .The rates of the new and serious DID were high .Conclusion The defense system of the drug-induced diseases caused by traditional Chinese medicine need to be established urgently which is used for collecting ,monitoring and analyzing the data of Chinese medicine drugs to the clinicians ,providing the information of rational use and advisory services by ef-fective ways and management measures ,and providing the basis to modify the specification for pharmaceutical manage-ment and administrative departments .As a result,it can minimize the incidence of drug-induced diseases and maintain the safety of the public takeing medicine .
