Objective To investigate the clinical efficacy of kidney-tonifying and blood-activating therapy on puberty polycystic ovarian syndrome(PCOS).Methods Thirty-one PCOS patients were randomly allocated into 2 groups:16 patients(TCM group)received kidney-tonifying and blood-activating Fuke No.5 Prescription combined with herbal medicine based on the menstrual cycle,and 15 patients(WM group)received oral administration of western medicine of diane-35.Changes of clinical symptoms and signs,B-ultrasonic results and serum hormones levels of follicle-stimulating hormone(FSH),luteinizing hormone(LH),prolactin(PRL),testosterone(T)and estrogen(E2)were examined before treatment,after treatment for 3 menstrual cycles and on the 3rd cycle after suspension.Results The menstuation and ovulation,serum sexual hormones(except FSH and E2)levels,and B-ultrasonic indexes(except the volume of uterus)were obviously improved in the two groups after treatment for 3 menstrual cycles(P0.05 compared with those before treatment),but remained at the levels after treatment for 3 menstrual cycles(P

ObjectiveIn order to improve the survival of graft liver after liver transplantation, this study was designed to investigate whether intraportal injection of 150mg/kg N-acetylcysteine (NAC) in rats could reduce hepatic ischemia-reperfusion injury after 48 h of cold storage and 2 h of reperfusion. Methods Healthy male Wistar rats weighing 250-350g were used. The study consisted of three groups: control group (group Ⅰ) ;NAC-treated group(group Ⅱ). 1 ml of 5% dextrose (D5%) or 1 ml D5% containing 150mg/ kg NAC was injected into the superior mesenteric vein. 15 min after the injection of D5 % or NAC the liver was flushed with cold (4℃) Ringer' s solution through the portal vein . After perfusion, the liver was removed and kept in 100 ml UW solution at 4℃ for 48 h. In group Ⅲ animals were pretreated with buthionine sulfoximine (BSO) 2 h before intraportal injection of D5 % or NAC and liver harvesting. After cold storage, the livers were then perfused for 2 h by a closed circulating system. Aspartate transaminase (AST), alanine transaminase (ALT), and lactate dehydrogenase (LDH) activities in the perfusate were determined by reflectometry. Lactate and acid phosphatase activities were determined by enzymatic methods. ResultsAfter 48 h of cold storage and 2 h of reperfusion, livers from NAC-treated group produced larger amounts of bile than those in the control group, and released less LDH, AST, ALT and acid phosphatase, a marker of Kupffer cell injury in the perfusate. The protective effects of NAC against cold ischemia-reperfusion liver injury were maintained when animals were pretreated with BSO, a specific inhibitor of glutathione synthesis. ConclusionsThis study shows that intraportal administration of NAC in vivo significantly improves the initial function of the isolated rat liver. Our results also indicate that NAC inhibits the activation of Kupffer cells, which are the first source of reactive oxygen intermediates during reperfusion.

Rectal cancer is a common type of malignant tumor, with increasing incidence over the previous years. Total mesorec-tal excision is the most important treatment for rectal cancer. Advanced rectal cancer presents high local recurrence rate and low sphinc-ter preservation rate. For locally advanced rectal cancer, neoadjuvant chemoradiotherapy is the optimal management strategy. In this re-gard, clinicians have focused on investigating the clinical effects of rectal cancer after neoadjuvant chemoradiotherapy. Prediction and evaluation of rectal cancer after neoadjuvant therapy can be used to determine further necessary treatments, effect on quality of life, and survival time of patients.
