OBJECTIVE:To establish a method for the content determination of Vincristine sulfate for injection. METHODS:HPLC was performed on the column of Agilent HC-C8 with mobile phase of 1.67% Diethylamine aqueous solution(adjusted to pH 7.5 with phosphoric acid)-methanol(38:62,V/V)at a flow rate of 1.0 ml/min,the detection wavelength was 297 nm,the column temperature was 35℃,and the injection volume was 10μl. RESULTS:The linear range of vincristine sulfate was 0.032-3.2 mg/ml (r=0.999 9);RSDs of precision,stability and reproducibility tests were lower than 1%;recovery was 99.3%-101.7%(RSD=0.6%,n=9). CONCLUSIONS:The method is accurate,reliable and sensitive,and can be used for the content determination of Vincristine sulfate for injection.

The imported schistosomiasis cases in the Chinese literature and reports from the infectious disease monitoring in-formation system from 1979 to 2013 were collected and compiled. Totally 365 cases were reported to be infected with outside schis-tosomiasis, including 239 cases of schistosomiasis haematobia (74.0%) and 71 cases of schistosomiasis mansoni (22.0%), and 42 foreigners (11.5%) and 323 Chinese (88.5%). The infection areas involved 15 countries and regions in Africa. Totally 74.92%of pa-tients worked in the construction or geological prospecting in the wild field. According to the analysis of these cases, we found that the management system of prevention and control of imported schistosomiasis cases was not perfect including the high missing re-port rate, high misdiagnosis rate, and no standard diagnostic criteria. We suggest that all the levels of CDC or health administrative authorities should adopt the following relevant control measures to strengthen the imported schistosomiasis prevention and control in order to reduce the damage to the public health and the risk of the spread of African schistosomiasis in China:1. to establish and perfect the imported schistosomiasis monitoring and control system in China;2. to integrate the dynamic information platform of la-bor export and establish the comprehensive prevention and control management system of infectious diseases;3. to standardize the diagnosis and treatment of oversea imported schistosomiasis; 4. to strengthen the research on the transmission risk of imported schistosomiasis in the territory of China.

Hepatic drug transporters(HDTs),including uptake transporters and efflux transporters, play an important role in drug distribution and elimination in the liver. The influx HDTs include organic anion transporters,organic cation transporters,organic anion transporter polypeptides and Na+-tauro-cholate cotransporting polypeptide. The efflux HDTs include multidrug resistance proteins,multidrug resistance-associated proteins,breast cancer resistance protein and bile salt export pumps. Major research methods involve gene knock-out animals,isolated perfused livers,liver slices,primary hepato-cytes and transfection cells. They have been used in study of drug distribution,drug-drug interaction and drug toxicity.

Objective To observe the effects of 8-week aerobic exercise on skeletal muscle glycogen content and exercise endurance and investigate the possible mechanism in rats with chronic heart failure. Methods 30 Sprague-Dawley rats were submitted to heart failure sedentary (H) group, heart failure traning (HT) group and sham operation (S) group. The heart failure model was established with coronary artery ligation. HT group performed an 8-week treadmill running. The skeletal muscle glycogen content was determined with anthracenone, exercise endurance with exhaust duration of graded exhausted exercise test, glucose uptake rate, activity of glycogen synthase (GS) and glycogen phosphorylase (GP) with radicisotope, protein expression of total GS, phospho-GS (p-GS), total GP and phospho-GP (p-GP) with Western Blotting. Correlation analysis was conducted between glycogen content and exhaust duration. Results The skeletal muscle glycogen, exhaust duration, glucose uptake rate, GS activity and p-GP protein reduced (P<0.05), while serum insulin, GP activity and p-GS protein raised (P<0.05) in the H group compared with those in the S group. The skeletal muscle glycogen, exhaust duration, glucose uptake rate, GS activity and p-GP protein increased (P<0.05), while serum insulin, GP activity and p-GS protein decreased (P<0.05) in the HT group compared with those in the H group. There was positive correlation between glycogen content and exhaust duration (P<0.05). Conclusion Prolonged aerobic exercise enhanced skeletal muscle glycogen content and exercise endurance in rats with chronic heart failure, which may be related to the improvement of insulin sensitivity, muscle glucose uptake, increase of glycogen synthesis and decrease of glycogen breakdown.
