Objective to investigate the efficacy of functional electrical stimulation(FES)on the postoperative treatment of lumbar disc hernia-tion. Methods Informed consents were obtained from all the subjects before the study. totally 60 patients who had remnant nervous lesion after sur-gery of lumbar disc herniation were divided into two groups:FES group and Control group. FES group received treatment since the first day after sur-gery. the parameters of therapeutic apparatus were as follows:35 Hz,0.28 ms,1 time daily and 30 min each time. the intensity of the treatment was the maximum tolerated that the patients can take. the course was 4 weeks. the control group during the study did not receive any stimulation. the myodynamia of hallux dorsiflexion and JOA score of patients were recorded and analyzed. Results After 2 weeks treatment,the myodynamia of FES group was 15.10±5.03,which was significantly larger than that of the control group at 12.03±6.30(P < 0.05). After 4 weeks treatment,the myody-namia of FES group was 20.43±5.73,which was significantly larger than that of the control group at 14.57±7.17(P < 0.05). After 4 weeks of treat-ment,the JOA score of FES group was 24.63±1.91,which was significantly higher than that of the control group at 19.87±2.33(P < 0.05). Conclu-sion After 2-4 weeks of functional electrical stimulation therapy,myodynamia of hallux dorsiflexion in FES group was significantly improved. And at the 4th week after operation,JOA score was more higher than that of the control group. Functional electrical stimulation in the treatment of remnant nervous lesion after postoperative of lumbar disc herniation has exact curative effect,which is worthy of popularization.

Objective To explore the expression and clinical significance of Twist. E-cadherin and N-cadherin in gallbladder carcinoma. Methods From 2000 to 2008, in Zhejiang Provincial People's Hospital, the expression of Twist, E-cadherin and N-cadherin protein were detected in 79 surgically removed gallbladder carcinoma tissue specimens in paraffin blocks and 20 normal gallbladder tissue specimens by tissue microarray technique and immunohistochemistry. Results Compared with normal gallbladder tissues, the expression of Twist and N-cadherin was up-regulated in gallbladder carcinoma tissues and the positive percentage was 68.3％ and 49.4％ respectively, while which both were 1/20 in normal gallbladder tissues. The percentage of high E-cadherin expression in gallbladder carcinoma tissues was only 27.8 ％, which was significantly lower than that in normal gallbladder tissues (20/20;X2 ＝29.31, P＜0. 05). The expression of Twist was correlated with T classification, lymph node metastasis, distant organ metastasis, hepatoduodenal ligament invasion, lymphatic invasion and UICC stage of gallbladder carcinoma (P＜0.05). The expression of E-cadherin was correlated with T classification, distant organ metastasis, hepatoduodenal ligament invasion, differentiation degree and UICC stage of gallbladder carcinoma (P＜0.05). The expression of N-cadherin was only correlated with lymphatic invasion of gallbladder carcinoma (P ＜0.05 ). There was significant negative correlation between Twist and E-cadherin expression (P＜0. 01). All the 79 gallbladder carcinoma patients were followed up after the surgery, the mean follow-up time was 30.6±14.3months. The 3-year survival rates of patients with low or high Twist expressions were 66％ and 7％ respectively,there was significant difference between the two groups(P＜0. 01). The 3-year survival rates of patients with low or high E-cadherin expressions were 25 ％ and 86 ％ respectively, the difference of two groups was significant(P＜0.01). The 3-year survival rates of patients with low or high Ncadherin expressions were 39％ and 41％ respectively, there was no significant difference between the two groups(P＞0.05). The multivariate analysis indicated that the Twist expression was one of independent prognostic factors of gallbladder carcinoma. Conclusion The abnormal expression of Twist and E-cadherin was correlated with the development and progression of gallbladder carcinoma,and Twist expression was one of the independent prognostic factors of gallbladder carcinoma.

Protocarcinogenic gene Her-2/neu was closely related to the development of gastric cancer. Herceptin is an antibody according to Her-2/neu and is used for treating breast cancer. Topo Ⅱ α is the important Nuclear enzymes needed by DNA duplicate, and is closely related to the proliferation of malignant tumors, so it is the important target enzymes of cancer chemotherapy. Her-2/neu and Topo Ⅱ α are located in the same chromosomes, there are correlation between the two genes' proliferation or loss. We reviewed the expression of Her-2/neu and Topo Ⅱ α in the stomach and the new progress of the correlation between the two genes home and abroad in this paper, which provides new methods for the prevention and treatment of gastric cancer.

Objective To explore the association of lipid metabolism and bomocysteine with hypertensive disorders in pregnancy and observe the inflammatory reaction and the pathological change of placenta.Methods We conducted a prospective randomized placebo-controlled study.Seventy-four cases with hypertensive disorders in pregnancy were recruited as the experimental group and 77 cases of normal pregnant women were recruited as matched control group from Aug.2008 to Mar.2010.The relationship between lipid metabolism and homocysteine was analyzed.Results There was significant difference between the two groups in body-mass index before pregnancy(29.03±4.52 vs.23.99±5.90,t =5.88),cholesterol[(6.16±1.48)mmol/L vs.(5.01±1.05) mmmol/L,t =5.52],low density lipoprotein[(3.46±1.35) mmol/L vs.(2.26±0.86) mmol/L,t =6.54]and C-reactive protein[(29.04±14.90) mmol/L vs.(15.48±4.57) mmol/L,t =7.62](P ＜ 0.05).No significant difference was found on triglycerides[(3.29±1.03) mmol/L vs.(3.49±1.37) mmol/L],high density lipoprotein[(1.84±0.40) mmol/L vs.(1.88±0.35) mmol/L],homocysteine [(8.77±2.65) mmol/L vs.(8.40±2.03) mmol/L]and neonatal weight[(3547±519)g vs.(3431±461)g](P ＞ 0.05).Significant difference exists in placenta pathology of infarction(54.55％ vs.31.04％),villi dysplasia,fit nodules form and hypoxia(65.46％ vs.39.66％)(P ＜0.05).Conclusion We should detect lipid,homocysteine and C-reactive protein by dynamic combinational ways,pay more attention to women with high BMI before pregnancy,and value placenta pathology research on hypertensive disorders in pregnant women.This has high clinical significance in revealing the etiology of hypertensive disorders in pregnant women and improving pregnant outcomes.

Objective In order to investigate the influence of reelin deficiency on the hippocampal development, the histochemical characteristics of hippocampal pyramidal cells and granule cells of reeler mice were analyzed, therefore, reelin's function would be better understood with more morphological evidences. Methods With immunofluorescent double labeling, the pyramidal cells, granule cells and mossy cells in hippocampi between wild type and reeler mice were labeled. Results The development and lamination of hippocampal cortical plate were in disorder. Pyramidal cells and granule cells dispersed, and moreover, granule cells proliferated rapidly and migrated into hilus, so that the bound between granule layer and hilus disappeared. Conclusion As a stop signal and regulatory signal, reelin plays important roles in neuronal migration of developing cortical plate, especially in the regulation of granule cell proliferation.
