Objective To observe the clinical efficacy of PHENIX electrical stimulation in preventing complications after missed abortion.Method A thousand patients receiving uterine cavity operation on missed abortion were randomized into two groups, 500 cases in each group. Patients in the two groups were asked to orally take Estradiol valerate, successively for 3 d prior to the operation. Right after the operation, the treatment group started to receive electrical stimulation at Guanyuanshu (BL 26) and Guanyuan (CV 4) via PHENIX USB 4/8 neuromuscular stimulation therapeutic apparatus, together with conventional preventive anti-inflammatory treatment; the control group only received the conventional preventive anti-inflammatory treatment after the operation. The colporrhagia duration and the resumption of menstruation in the two groups were observed, and the menstruation, postoperative adhesion ratio and adhesion rate were compared between the two groups.Result There were significant differences in comparing the duration of colporrhagia and the time of the resumption of menstruation after the operation between the two groups (P<0.05); there were significant differences in comparing the postoperative menstruation, intrauterine adhesion ratio and adhesion rate between the two groups (P<0.05).Conclusion PHENIX electrical stimulation can shorten the time of colporrhagia after missed abortion, promote the resumption of menstruation, and effectively prevent intrauterine adhesions.

Objective To observe the effect of erythropoietin(EPO)on apoptosis and glycogen synthase kinase-3?(GSK-3?)level in newborn rats with hypoxic-ischemic brain damage(HIBD).Methods Thirty 7-day-old neonatal rats were randomly divided into 3 groups:sham-operated group,hypoxic-ischemic(HI)group and EPO group.Rats in HI group and EPO group were subjected to left common carotid artery ligation,and then they were exposed to 80 mL/L oxygen and 920 mL/L nitrogen gas in the sealed containers of 37 ℃ for up to 2.5 hours to establish HIBD models.EPO was injected intraperitoneally into the EPO group rats after operation,Solution was injected into the first 2 groups.All rats were killed at the 24 hours after operations,The apoptosis was identified and analyzed by flow cytometry.The level of GSK-3? was detected by enzyme-linked immumosorbent assay.Results The neuronal apoptosis and GSK-3? content in the cortex and hippocampus tissue in HI group were significantly higher than those in the sham-operated group(Pa

Objective To analyze the dermal irritation characteristics of 8 types of cosmetics.Methods The selected 917 cosmetics samples of 8 types,which were underwent the health safety test in China during 2005-2007,were assessed in the acute dermal irritation according to the related standards and the data were statistically analyzed using CMH method.Results The dermal-irritant samples were detected in different levels in 8 types of cosmetics.In terms of the irritation of cosmetics and the dermal damage caused by cosmetics,the cosmetics for hair,for face clean and for bath showed a significant higher proportion compared with the other types of cosmetics and the dermal damage could last for more than 14 days.Conclusion The acute dermal-irritability is different in 8 types of cosmetics,the cosmetics for hair,for face clean and for bath can cause the irritation and damage in the skin in degrees.

Objective To compare the clinical efficacy of endoscopic variceal ligation versus pericardial devascularization in the treatment of portal hypertension.Methods The clinical data of 101 cirrhotic patients with gastroesophageal varices and variceal hemorrhage from January 2010 to January 2012 were analyzed.Fifty-three patients received endoscopic variceal ligation,and forty-eight patients received pericardial devascularization.Postoperative changes in liver function and hypersplenism were compared between the two groups.The rate of rehaemorrhagia and incidence of postoperative complications after surgery were compared as well.Continuous data were expressed as mean ±SD,and categori-cal data were expressed as number of cases or percentage.Comparison of continuous data between the two groups was made by independent-samples t test,and comparison of categorical data was made by chi-square test.Results After surgery,the variceal ligation group showed no significant changes in liver reserve function,while the albumin level was significantly decreased in the pericardial devascularization group (t=2.512,P<0.05).There were no significant changes in the counts of white blood cells and platelets in the endoscopic variceal ligation group after surgery (P>0.05),but significant increases in the counts of white blood cells and platelets were detected in the pericardial devascular-ization group (P<0.05).The rates of postoperative haemorrhage in the two groups were:3 months,7.5%vs 6.2%(χ2 =0.066,P>0.05), 6 months,7.5%vs 8.3%(χ2 =0.021,P>0.05),and 1 year,9.4%vs 8.3%(χ2 =0.038,P>0.05).The incidence rates of postopera-tive complications in the two groups were 24.5%and 50%,respectively (χ2 =7.040,P<0.05).Conclusion Compared with pericardial devascularization,endoscopic variceal ligation causes fewer microlesions,preserves liver function,and leads to a lower incidence of postopera-tive complications.However,if hypersplenism is observed in the cirrhotic patients with gastroesophageal varices and variceal hemorrhage,peri-cardial devascularization can be used to control the hypersplenism and prevent esophageal hemorrhage.

Objective To elucidate the role of insulin receptor and its ?-subunit autophosphorylation in evoking insulin resistance in non-obese type 2 diabetes. Methods 14 patients with non-obese type 2 diabetes and 12 healthy subjects were enrolled in this study. Insulin receptor numbers and its insulin affinity in erythrocytes were measured using radio-labelled ligand binding assay described by Comi et al. Insulin receptor autophosphorylation in erythrocytes membrane was initiated by adding insulin and ?- 32 P ATP. Then the membrane proteins were resolved on 7 5% SDS-PAGE and subjected to autoradiography. Results The numbers of high and low affinity receptors in erythrocytes of type 2 diabetes were 21?13 and 955?427 per cell respectively, and they showed no significant difference as compared with control. The high affinity constant(K 1) and low affinity constant(K 2) of insulin receptors in erythrocytes of type 2 diabetes were (1 70?0 93)?10 -9 LM -1 and (1 44?0 86)?10 -7 LM -1 respectively, also displaying no significant difference in comparison with the control. Insulin-induced receptor ? subunit autophosphorylation was 8 02?5 6△A/mg protein in type 2 diabetes, which was lower than that (28 38?15 24)△A/mg protein) in control(P
