Objective To study the efficacy of complete hemihepatic vascular exclusion (CHVE) in the prevention of tumour dissemination during liver resection for hepatocellular carcinoma (HCC).MethodsA case-control study was carried out on 281 patients who underwent liver resection for HCC between February 2006 and April 2010.89 patients underwent hepatic resection using CHVE (group A) and 192 using Pringle maneuver (group B).The postoperative 1-,2-,3 year rates of intrahepatic recurrence and lung metastasis,and the overall disease-free survivals were compared between the two groups.ResultsThe incidence of lung metastasis at 1 year after operation was significantly lower in group A than group B (6.7％ vs.15.1％,P=0.048).There were no signilicant differences in the incidences of lung metastasis at postoperative year 2 and 3 between the two groups (15.7％ vs.25.0％ and 32.6％ vs.30.7％ ; P＞0.05).The differences in the postoperative 1-,2-,3- year intrahepatic recurrence rates were not significant between the two groups (20.2％ vs.31.8％,51.7％ vs.60.3％,68.5％ vs.79.2％,respectively; P＞0.05).The median survivals of the two groups were 25.9 months and 21.7 months,respectively.Patients in group A had a significantly higher overall disease-free survival rate than patients in group B (P=0.035).ConclusionsCHVE was efficacious in reducing the incidence of lung metastasis and in improving the overall disease-free survival in patients after liver resection for HCC.CHVE contributed in preventing intraoperative tumour dissemination and in improving prognosis.

Objective To observe the effect of Chinese Medicines with the function of antioxidation on lupus nephritis(LN)pa- tients.Methods The 25 LN patients consisting of renal function normal group(15 cases)and renal failure group(10 cases)were treated with Huang Qi(Radix Hedysari)and Shu Dihuang(Radix Rehmanniae Praeparata)as main ingredients for 6 months in suc- cession.Changes of symptom,systemic lupus erythematosus disease activity index(SLEDAI),activity index(AI),lipid peroxide (LPO),superoxide dismutase(SOD),glutathione peroxide(GSH-Px),malondialchehyche(MDA),nitric oxide(NO),blood and urine routine examination,24-hour urine protein quantity,liver and kidney function,anti-double-stranded DNA(anti ds-DNA),complement 3(C_3)and complement 4(C_4),after treatment were observed.Results SLEDAI and AI scores were remarkably different from those before treatment(P

Objective To investigate the disease occurrence-related factors and severity of alcoholic hepatitis (AH) and alcoholic liver cirrhosis (ALC).Methods According to the clinical diagnostic criteria that were passed by the 2010 Chinese Society of Fatty Liver Hepatology and alcoholic liver disease study group,the clinical data of 241 AH and ALC patients were analyzed.Results The amount of liquor taken daily,the time limit of drinking,and total amount of liquor taken in ALC patients were significantly different from those in AH patients (P ＜0.01),respectively.In ALC patients,the proportion (48.39％)of workers,peasants,and unemployed low-income alcoholics was significantly higher than that (25.58％)in AH patients (P ＜0.01).Laboratory tests showed the AST/ALT ratio in the ALC group (2.63 ±4.74)was significantly higher than that in the AH group (1.01 ±0.52) (P ＜0.01); TG [(1.33±1.24)mmol/L] and cholesterol (CHOL) [(3.14 ± 1.25) mmol/L] in ALC group were significantly lower than TG [(2.29 ± 1.60)mmol/L] and CHOL [(4.27 ±0.79)mmol/L] in the AH group (P ＜0.01).Conclusions Alcoholic liver disease occurrence and severity were related to the amount of liquor taken,the time limit of drinking,and the work ; AST/ALT ratio,TG and CHOL values were consistent with the severity of alcoholic liver disease.

Objective To evaluate the optimal dosage of misoprostol administered in the rectum for dilation of the cervix. Methods Two hundred and forty women at 40-60 day gestational age without vaginal delivery history were randomly divided into three groups,with 80 cases in each group. Patients received 200,400 or 600μg of misoprostol rectally one hour before electrical vacuum abortions in group A,B and C,respectively. Cervical dilation,blood loss,and drug side effects in the three groups were compared. Venous blood samples were taken before vein anesthesia,and misoprostol acid concentration in the serum was tested by liquid chromatography-mass spectrometry. Results The analgesic rate was 100. 00%in all three dose groups, and cervical dilation rate was 23. 75%,46. 25%and 70. 00%in groups A,B and C,respectively. The severity of drug side effects such as vaginal bleeding and abdominal pain is dose-dependent. Blood concentration of misoprostal acid was(117±65),(206± 98),and(303±149)pg·mL-1 ,in groups A,B and C,respectively. Conclusion The recommended dose of misoprostol is 400 μg administered in rectum. Rectal administration of misoprostol is cheap,safe,and convenient,and therefore could be widely applied.

Objective To observe the anti-androgenic activity of two pyrethroids (cypermethrin and fenpropathrin) in vivo. Methods SD rats aged 6 weeks were castrated ,and then housed for one week. The rats were randomly divided into groups, six in each: negative control group,cypermethrin and fenpropathrin group, positive control group. The rats were subcutaneously injected with testosterone propionate (TP) 100 ?g(/kg?d)for 7 consecutive days. Peanut oil, cypermethrin [ 45, 90, 180 mg/(kg?d)], fenpropathrin[10, 20, 40 mg/ (kg?d) ], flutamide[ 20 mg(/kg?d) ] were subcutaneously injected for 7 consecutive days at the same time. The sex accessory glands and serum hormone were detected. Results Compared with the negative group, no significant differences were observed in the sex accessory glands/tissues (seminal vesicles with coagulating glands, dorsolateral prostate, the ventral prostate and levator ani muscles) and the levels of serum hormones of the pyrethroids groups. Compared with the negative group, the masses of all the sex accessory glands/tissues decreased significantly in the positive group . Compared with the negative group, the level of LH increased significantly in the positive group. Conclusion No obvious anti-androgenic effects induced by cypermethrin and fenpropathrin in castrated SD rats has been observed.

Objective To understand the situation of benzene series compounds pollution inside some Passenger cars in Tangshan and provide data for the formulation of corresponding countermeasures for the prevention and control of the pollution. Methods One hundred and twenty-two cars used for different periods of time were selected from March, 2009 to May, 2009 and the concentrations of benzene,toluene and xylene were determined.At the same time the basic situation (car type, date of manufacture) was investigated with questionnaire. Results The disqualified rate of benzene, toluene, xylene were 14.8%(18/122), 26.2%(32/122) and 20.5%(25/122) respectively. Eighty-one cars did not meet the standard, accounting for 66.4 %(81/122). The median of benzene, toluene, xylene in the cars used within six months were 0.086, 0.900, 0.400 mg/m3 respectively. The exceeded rate of benzene, toluene, xylene inside the cars which were used for not more than six months were 28.6%(10/35), 57.1%(20/35), 60.0%(21/35) respectively. The concentrations of benzene series compounds decreased gradually later on. The concentrations of benzene inside the cars with adsorbent were lower, the concentrations of toluene inside the highgrade cars were higher and the concentrations of xylene inside the cars with leather seats was higher. Conclusion Benzene, toluene, xylene pollution inside cars has been showed in this investigation in Tangshan. The concentrations of benzene series compounds are associated with using time, adsorbent, car grade and the seat material.
