Objective and Methods: Thirty-three patients with peri-menopausal syndrome were treated by electroacupuncture of points Guanyuan (CV 4) and Sanyinjiao (SP 6) according to the principle of regulating and tonifying the Thoroughfare and Conception vessels, and the curative effects were analyzed.Results and Conclusion: The results showed that there was a significant difference in the clinical symptoms of the patients with peri-menopausal syndrome between pre- and post-electroacupuncture of points Guanyuan (CV 4) and Sanyinjiao (CV 6) and the clinical effective rate reached 93.9%. The measurement of sexual hormones showed E2, FSH and LH levels were better after treatment than before treatment in the patients with peri-menopausal syndrome. The analyses indicated that electroacupuncture of points Guanyuan (CV 4) and Sanyinjiao (CV 6) could relieve the clinical symptoms in the patients with peri-menopausal syndrome and improve the patient's life quality.

Objective To investigate the causes of and prophylactic measure for complications of minilaparotomy cholecystectomy (MC).Methods The clinical data of 10 200 patients receiving MC from Apri1 1991 to March 2006 were analyzed.Results MC was successful in 9 835 cases(96.4%), and in 365 cases(3.6%) the incision was lengthened. Serious complications were 12 cases(0.12%)of bi1e duct injury, 4 cases(0.04%)of colon injury, 8 cases(0.08%)of massive haemorrhage, and 25 cases (0.25%)of bile leakage. Four 4 cases(0.04%) died. Conclusions The key to prevention of complications is a strict selection of MC indications,careful identification of the anatomical structures of Calot's triangle,use of suture ligation of the mesentery of gallbladder triangle and the technique of deep knot-tying and the timely use of extension of the incision.

Objective To construct the murine allogeneic acute GVHD model.Methods C57BL/6 (H-2b) mice were used as the donors and Balb/c (H-2d) mice as the recipients in allogeneic bone marrow transplantation (BMT).Groups were set as total body radiation (TBI) control group (n =4),GVHD group (n =10),simple BM transplantation group (n =10) and normal control group (n =4).For TBI control group,mice were subjected to TBI but did not receive BMT after radiation.For GVHD group,5 days before TBI,gentamycin (320 mg/L) and erythromycin (250 mg/L) were added into the drinking water,and on the day of transplantation,mice received one total dose of 8.0 Gy 60Coγ TBI,and within 5 h,2 × 106 C57BL/6 BM cells and 1 × 107 C57BL/6 spleen cells were transfused per mouse via the tail vein.For simple BMT group,the pretreatment was the same as GVHD group,and mice received only 2 × 106 C57BL/6 BM cells per mouse via the tail vein.The mental status,activity,posture,fur,weight,and stool were observed after transplantation.Survival time of each mouse was recorded,survival rate was calculated,and survival curve was drawn.Pathological examination was done for the liver,skin,small intestine and BM on the brink of death.Results The median survival time (MST) in TBI control group,GVHD group and BMT group was (9.0 ± 0.7),(32.0 ± 3.2) and ( 17.5 ± 1.6) days respectively,and there was significant difference between every two groups (P ＜ 0.01 ).Pathological examination in TBI control group showedhematopoiesis exhaustion.GVHD group showed acute GVHD symptoms 10-13 days after allo-BMT,and the pathological changes of the skin,liver and small intestine corresponded to those of Ⅰ to Ⅱ degree of GVHD.Simple BMT group also showed acute GVHD symptoms 10-13 days after alloBMT,but their GVHD manifestation and histological changes were less serious and only 0 to Ⅰ degree of GVHD could be seen.ConclusionStable acute GVHD model can be constructed by transfusion of allogeneic BM cells and spleen cells into Balb/c mice after lethal TBI.

Purpose To Investigate the effect of diet-induced hyperchole sterolemia on the kidney ofWistar rats. Methods Male Wistar rats were fed with normal chow supplemented with 5 % cholesteroland observed biochemical changes in plasma lipid concentration, urinary microalbumin excretion, renalfunction, lipid component in renal cortices and morphological changes at 30,60 and 90 days. ResultsTotal plasma cholesterol (TCh) and low density lipoprotein (LDL) concentration were significantly elevatedin the group E (P＜0.05)at 30 days, and progressively increased thereafter, but during the entire study,there ere no differences in plasma urea nitrogen(BUN),creatinine(Cr), and endogenous creatinine clearance(Ccr) between the two groups. Quantitative urinary microalbumin excration was markely elevated in group E( P ＜ 0.05 ). Cholesterol (Ch), phosphatidylcholine(PC) and phosphatidylethanolamine(PE) levels of t he renalcortices were sigificantly increased in the group E at 12 weeks. Progressive development in mesangialhypercellulary, increased mesangial matrix, glomerular capillaries collapes were observed in the group E. Noelectron dense deposits were observed in any of the glomeruli examined. There was a siginificant positivecorrelation for the urinary microalbumin, Ch in the renal corticres, and glomerular size with plasma TCh andLDL concentration. Conclusions The diet-induced hypercholesterolemia may cause lipid nephrotoxicity inWistar rats.

0.05).The Cormack and Lehane laryngeal exposure grades obtained by the Macintosh laryngoscope with and without ELM were significantly different(Z=3.55 P0.05).Of all 33 pediatric patients,successful orotracheal intubation using the GSLV was completed by one attempt in 31 patients and by 2 attempts in 2 cases.The time required to achieve successful tracheal intubation was 20-51(30.0? 7.9) s.Conclusions GSLV is as useful as Macintosh laryngoscope for laryngeal exposure and orotracheal intubation in children.When the orotracheal intubation is done using the GSLV in children,the distal end of a styletted endotracheal tube should be bent anteriorly to an angle of 70-80 degrees and ELM is routinely used.

AIM: To explore the mechanism underlying inducible nitric oxide (NO) caused injury of endothelial cells during inflammation. METHODS: The activity of iso-enzymes of NO synthase (NOS), NO level and iNOS expression were examined using NADPH method, Griess reaction and RT-PCR, respectively. Furthermore, the lactate dehydrogenase (LDH) release rate, malondialdehyde (MDA) content were also measured. RESULTS:Co-administration of cytokines (TNF-? 5?10 5 U/L, IL-1? 2?10 5 U/L, INF-? 2?10 5 U/L) and LPS (10 mg/L) caused an obvious increase in NOS activity, NO levels (about two-fold) and a significant injury of the cells. At the same time, a significant increase in iNOS mRNA was also detected. Wheareas, treatment of the cells separately with cytokines or LPS for 24 h had no significant effect on NOS activity and NO level in cell lysates, however, it caused a significant increase in LDH release and MDA content. Also, the effect of cytokines and LPS on cell viability was concentration-and time-dependent. L-NMMA, a inhibitor of NOS, can suppress inducible NO production and protect cells against NO induced injury. CONCLUSION:Co-administration of cytokines (TNF-?, IL-1? and INF-?) and LPS significant activated iNOS and NO production which, in turn, induced oxidative reaction in endothelial cells.
