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.

Background As assessment of the peripapillary retinal nerve fiber layer (RNFL) has been an important approach for detecting structural damage in patients with glaucoma and myopia is a vital risk factor of primary open glaucoma,it is urgent to establish the correlation between RNFL thickness and myopia,not only for understanding the characteristics of RNFL with the change of the degree of myopia,but also for identifying those myopic patients with the early stage of glaucoma.Objective This study was to assess the influence of myopia for the thickness of RNFL measured by 3D optical coherence tomography (3D-OCT).Methods Two hundred and fifty-eight eyes of 258 myopic subjects from General Hospital of Ningxia Medical University were recruited.The myopic eyes were divided into low myopia group (42 eyes,-0.5 D ≤ SE ≤-3.0 D),middle myopia group (120 eyes,-3.0 D＜SE≤-6.0 D),high myopia group (58 eyes,-6.0 D＜SE≤-8.0 D) and extreme high myopia group (38 eyes,SE ＞-8.0 D).The peripapillary RNFL thickness profile including temporal,superior,nasal and inferior quadrants and each of the 12 clocks was measured by 3D-OCT.The measured values were compared among different degrees of myopia,and the correlations between spherical equivalent (SE) and axial length with RNFL thickness were analyzed using linear regression equation.Results The RNFL thickness was gradually declined with the increase of SE and elongation of axis,showing significant differences among the 4 groups in the superior,nasal and inferior quadrants and mean RNFL thickness (F=10.48,15.60,3.31,8.98,all at P＜0.05),but temporal RNFL thickness was increased with the SE rise,with markedly difference among the 4 groups (F =2.92,P =0.03) ; and RNFL thicknesses in the superior,nasal,inferior quadrants and mean RNFL thickness were evidently declined in the high and extreme high myopia group in comparison with low myopia group (all at P＜0.05).The overall RNFL parameters at 1:00,2:00,3:00,4:00,5:00,6:00,8:00,12:00 o'clock sectors were thinning as the increase of SE (all at P＜0.05) and unchanged at the 7:00,9:00,10:00,11:00 sectors in different SE groups (all at P＞ 0.05).Negative correlations were found between axial length or SE with the RNFL thicknesses at superior,nasal and inferior quadrants,average thickness as well as 1:00,2:00,3:00,4:00,5:00,6:00,11:00,12:00 o 'clock,and positive correlation was seen between the axial length or SE with the RNFL thicknesses at temporal quadrant.Conclusions The thickness of RNFL varys with the different degree of myopia and axial length.

[Objective] To investigate the effects of mitochondrial unfolded-protein response (UPRmt) on the aggregation toxicity of Aβ protein in Alzheimer's disease (AD).[Methods] By cloning the mitochondrial outer membrane tomm-22,inner membrane E04A4.5 and atfs-1 genes of Caenorhabditis elegans (C.elegans) and constructing the L4440 interference vectors,HT115 competent cells were transformed to prepare tomm-22,E04A4.5 and atfs-1 RNAi bacteria.The effects of tomm-22 and E04A4.5 RNAi on the process of paralysis were investigated through transgenic AD disease models CL4176 and CL2006.The life span of wild type N2 C.elegans was observed after RNAi of tomm-22 and E04A4.5.The regulatory role of ATFS-1 signaling by atfs-1 RNAi in inhibition of Aβ protein aggregation was detected.The dynamic changes of UPRmt in transgenic SJ4100 nematode and the autophagy level in transgenic DA2123 nematodes were analyzed by tomm-22 and E04A4.5 RNAi.[Results] We successfully established the UPRmt model by cloning mitochondrial tomm-22 and E04A4.5 of C.elegans and further constructing RNAi bacteria,and showed that they can suppress aggregation toxicity of Amyloid-β (Aβ) protein in AD model CL4176,and slow down paralysis process.The life span of wild type N2 was significantly shortened after feeding with the tomm-22 and E04A4.5 RNAi bacteria.At the same time,the progressive paralysis AD model CL2006 shows a delayed paralysis in the early stage of life cycle but get acceleration in the late.These results illustrate that the UPRmt can alleviate the mitochondrial stress and improve the function of mitochondria at least in the short term.The atfs-1 RNAi confirmed that delayed paralysis process of AD model CL4176 is not directly related to the ATFS-1 signal.However,tomm-22 and E04A4.5 RNAi can gradually increase the UPRmt response and induce the expression level of autophagy-related molecules LGG-1,suggesting that tomm-22 and E04A4.5 RNAi may play a role in delaying the AD disease process by enhancing the activity of autophagy in C.elegans.[Conclusions] The study found that the UPRmt can inhibit the accumulation of A β protein by coordinating the signal transduction between mitochondria and nucleus,and can help to restore mitochondria and even intracellular protein homeostasis for protecting the normal physiological function of cells,and also provides new targets for prevention and treatment of neurodegenerative diseases such as AD.

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 imaging features of intra-osseous ganglia surrounding the ankle joints and their diagnostic value.Methods Imaging features of 40 cases of intra-osseous ganglia proved by the pathology from 1 982 to 2012 were analyzed ret-rospectively.33 cases underwent radiography,26 cases underwent computed tomography (CT)and 13 cases underwent magnetic resonance imaging (MRI).Results Intra-osseous ganglia were detected at talus in 23 cases,distal tibia in 1 5 cases (8 cases in pos-terior melleolus,6 cases in medial melloulus and 1 case in anterior part of distal tibia),and lateral malleolus in 1 case.Multiple in-tra-osseous ganglia was detected in 1 case,which located in both talus and posterior malleolus.29 cases were oval,monolocular os-teolytic lesions.1 1 cases were multilocular lesions with separation.All cases were observed with slightly sclerous edge.Articular surface disruptions were observed in 1 5 cases,and lesions were connected with the joint space.① Oval cystic translucent areas with sharp and sclerous edge adjacent to the ankle joint were observed in 34 lesions of 33 cases on radiograph.Cracks were noted on the articular surface of 12 lesions.② Round translucent areas with sharp and sclerous edge were observed in 26 isolated lesions on CT images.Cracks were noted on the articular surface of 14 lesions.③ 14 lesions of 13 cases showed low to moderate signal on T1 WI and high signal on T2 WI.Cracks were observed in 4 lesions adjacent to the ankle joint,and soft tissue swelling was noted in 6 le-sions.Conclusion Intra-osseous ganglia can be diagnosed accurately based on the typical imaging features and special locations.

Objective To compare the 2 methods of the flow cytometry and the microcolumn gel agglutination assay for testing anti-ABO Ig G antibody.Methods The flow cytometry and the microcolumn gel agglutination assay were adopted to detect the an-ti-ABO IgG antibody in the O blood type pregnant women(experimental group)and the A/B blood type pregnant women (control group).The difference in the positive rates between the experimental and control groups and the correlation between these two methods were analysed.The different titers of samples were selected for detection on different days to compare their reproducibili-ty.Results 300 samples from the experimental goup and 300 samples from the control group were collected.The detection results of 2 methods showed that the positive rates of the experimental group was significantly higher than that of the control group with statistical difference(P <0.05).The correlation coefficients(rs )between these two methods were 0.694.The coefficient of variation in the flow cytometry was smaller than that in the microcolumn gel agglutination assay(P <0.05).Conclusion ABO blood type in-compatibility is more common in O type pregnant women.The flow cytometry and the microcolumn gel agglutination assay possess good correlation.The reproducibility of the flow cytometry is better than that of microcolumn gel agglutination assay.
