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 investigate the expression and significance of estrogen receptor alpha in renal tissue of immunoglobulin A (IgA) nephropathy.Methods Fifty renal tissue samples including forty five cases of IgA nephropathy and five cases of normal expression were collected.The expression of estrogen receptor αt (ERα) was detected by immunohistochemistry method,and its relationship with clinical parameters and the degree of glomerular damage were analyzed.Results ERα was located in the glomerular and renal tubules.With the severity of the lesion,the expression of ERα in renal tissue of IgA nephropathy decreased gradually (P =0.001) and its expression was associated with estimated glomerular filtration rate (eGFR),serum creatinine (Scr),and pathologic grade of IgA nephropathy (r =0.876,-0.818,and -0.736,P < 0.05),The expression of ERα was significantly decreased in hypertensive patients with IgA nephropathy,and the difference was statistically significant compared with that in non-hypertensive group (P =0.011).Conclusions The expression of ERα in renal tissue of IgA nephropathy was significantly decreased and there was a correlation between the degree of renal tissue damage,suggesting that ERα might play a role in the development of renal disease.

Objective To investigate the mRNA expression of UPA and MMP-9 in gastric carcinoma and their correlation with histological type, growth-type, differentiation, vessel invasion, metastasis and prognosis. MethodsIn situ hybridization was used to detect the mRNA expression of UPA and MMP-9. ResultsIn situ hybridization revealed that among 105 cases, the positive rates of UPA mRNA and MMP-9 mRNA were both 58.1%. There was no significant relationship between UPA mRNA and histological type( r _ s = 0.123, P =0.210)and differentiation ( r _ s =0.102, P =0.298)of the tumor. However, there was a significant difference between growth-type( r _ s =0.344, P =0.001),tumor invasion depth( r _ s =0.296, P =0.002),vessel invasion( r _ s =0.198, P =0.042),lymph node( r _ s =0.332, P =0.001)and distant metastasis( r _ s =0.530, P =0.001);there was no significant relationship between MMP-9 mRNA staining and histological type( r _ s =0.143, P =0.145)and differentiation( r _ s =0.102, P =0.298)of the tumor. However, there was a statistically significant difference between growth-type( r _ s =0.267, P =0.006),tumor invasion depth ( r _ s =0.335, P =0.001)、vessel invasion( r _ s =0.209, P =0.032),lymph node( r _ s =0.343, P =0.001)and distant metastasis( r _ s =0.468, P =0.001);There was a positive relationship between UPA mRNA and MMP-9 mRNA expression( r _ s =0.237, P =0.015). The mean survival time in cases with positive UPA mRNA and MMP-9 mRNA expression were significantly shorter than that of cases with negative expression. ConclusionThe mRNA expression of UPA and MMP-9 can predict the invasion and metastasis of gastric carcinoma, They can be used as markers of prognosis of gastric carcinoma in clinical practice.

Objective: To investigate the relationship of loss of P16 expression with biologlical behaviors and prognosis of gastrointestinal stromal tumors(GISTs). Methods: The expression of P16 protein and mRNA was detected in GISTs tissues by immunohistochemistry,Western blot and RT-PCR.The prognosis was evaluated through follow up. Results: The expression rates of P16 protein and mRNA in GISTs were 53.8%(21/39,Frozen tissue),51.3%(20/39,Frozen tissues)and 51.4%(37/72,Paraffin-embedded tissues),respectively.The expression of P16 was significantly different among GISTs of different aggressive risk(P<0.05).With the incease of aggressive risk,the expression of P16 was deceased.The expression of P16 was negtively correlated with Ki-67 and patient survival(P<0.05). Conclusion: The loss of P16 expression has a positive correlation with the infiltration and progression of GIST.Detection of P16 protein and mRNA is helpful for the evalutaion of biological behaviors and prognosis of gastrointestinal stromal tumors.
