ObjectiveTo observe the effect ofZuogui Jiangtang Jieyu Formula on the expressions of glutamate, NR2A and NR2B in hippocampus of diabetic rats with depression;To explore the mechanism of protective effect. Methods Diabetes with depression rat models were established and then were randomly divided into the model group, positive medicine group, high-, medium- and low-doseZuogui Jiangtang Jieyu Formula groups. Normal rats acted as normal group, 16 rats per group. After 28 days of administration, Open-field test was used to detect the behavior of the rats;glutamate content of hippocampus was detected by ELISA;the expressions of NR2A and NR2B in rat hippocampus were detected by immunofluorescence.Results Compared with normal group, automatic activity times of rats in model group decreased significantly (P<0.01);both glutamate content (P<0.01) and expressions of NR2A, NR2B (P<0.01) increased significantly. Compared with the model group, automatic activity times of rats in positive medicine group and high-doseZuogui Jiangtang Jieyu Formula group significantly increased (P<0.01);glutamate content dropped (P<0.01);expressions of NR2A and NR2B decreased (P<0.05).ConclusionZuogui Jiangtang Jieyu Formula can improve depressive behavior of diabetic rats with depression, which may be related to the regulation of glutamate content and expressions of NR2A and NR2B in hippocampus.

Objective:To investigate the role of transcription factor SP1 decoy oligodeoxynucleotides(ODN) on expression of ? Gal in SV-40-PED cells.Methods:Immortalized porcine aortic endothelial cells of the PED line were cultured and transfected with ?1,3galactosyltransferase(?1,3GT) specific decoy ODN.Cells transfected with mismatch ODN was used as negative controls.Twenty-six hours later the cells were collected.The expression of ? Gal was determined with fluorescence microscope and Western blot.The expression of ?1,3GT mRNA was examined by RT-PCR.Results:Fluorescence microscopy observed the decreased fluorescence of ? Gal after decoy ODN transfection.Western blot showed that the average absorbance of the PED cells transfected with decoy ODNs was(48.2?0.9).It is 52.6% of the mock group(P0.05).Conclusion:?1,3GT gene reduce actually occurs following transfection of decoy ODN.Porcine endothelial cells can be the targets of decoy ODN.

AlM:To investigate the expression transforming growth factor-β1 (TGF-β1) and heat shock protein 47 (HSP-47), in pterygium and normal conjunctiva tissues, in order to study the roles of these cytokines played in the pathogenesis in human pterygium.
METHODS:The expression difference of TGF-β1, HSP-47 between human pterygium and normal conjunctive tissues were compared by immuno - histochemistry technique.
RESULTS:The positive expression of TGF-β1, HSP-47 was stronger than in normal conjunctive tissues ( P <0. 05), the TGF-β1 expressed in all layers of pterygium, especially in the squamous epithelium, in the inflammation cells and vascular endothelial cells also expressed. The HSP-47 showed higher expressed in the lamina propria layer of pterygium, and weakly expressed in epithelial layer, no obvious expression in normal conjunctive tissues.
CONCLUSlON:Over-expression of TGF-β1 and HSP-47 in pterygium compared to the normal conjunctiva tissues may play a critical role during the occurrence, development and invasion of the pterygium.

OBJECTIVETo investigate the treatment of chyle leak following radical resection for colorectal cancer.

METHODSThe incidence of chyle leak was compared between the different surgical approaches (open vs. laparoscopic) as well as different tumor locations (right, left colon or rectum) in 1259 patients undergoing radical resection for colorectal cancer.

RESULTSOverall incidence of chyle leak was 3.6% (46/1259) after surgery. Forty-five patients were successfully managed by conservative treatment and one patient required re-operation. No patients died. The incidence of chyle leak was not significantly different between the open (3.2%, 18/570) and laparoscopic (4.1%, 28/689) groups (P>0.05). However, right colectomy was associated with a significantly higher rate of chyle leak (9.6%, 16/167) as compared to left colectomy(2.6%, 7/268) and anterior resection (2.8%, 23/824) (P<0.05).

CONCLUSIONSConservative treatment is effective in early stage of chyle leak after radical resection for colorectal cancer. Right colectomy is associated with higher risk for chyle leak.

Objective· To compare the impacts on clinical efficiency and safety between 0.014 inch Synchro microwire and Transend microwire used during mechanical thrombectomy for acute ischemic stroke (AIS) caused by large artery occlusion.Methods· Forty-six patients undergoing mechanical thrombectomy with stent retrievers between October 2012 and January 2016 were included,who were classified into Synchro group (21cases) and Transend group (25 cases).The clinical outcome,procedure time,and safety were analyzed and compared between two groups.Results· The recanalization rates were similar between two groups (P=0.600),but time from puncture to vascular recanalization of Synchro group was much shorter than that of Transend goup (48.88 min vs 82.33 min,P=0.001).The rates of functional independence (modified Rankin scale score ≤ 2) were similar between two groups (P=1.000).There was no significant difference of the rates of post-procedure subarachnoid hemorrhage (PSAH) between two groups (P=1.000).However,there were two cases that had fatal subarachnoid hemorrhage with intracranial hematoma in Transend group,while there was only one case of mild subarachnoid hemorrhage who recovered well in Synchro group.Conclusion· Compared with Transend microwire,Synchro microwire can significantly shorten the procedure time of mechanical thrombectomy,and the risk of fatal subarachnoid hemorrhage is rather small.

Objective A resistin binding peptide (RBP) was selected by phage display in our previous work. Studies had shown that RBP could antagonize the role of resistin on the lipid metabolism and endocrine function of adipose tissue, but whether RBP affects the insulin secretion of pancreatic cells is still unknown. The aim of this study is to assess the effect of RBP on basal insulin secretion in RINm5F insulinoma cells. Methods The cell viability was measured by 3-[4,5-dimethyhhiazol-2-yl]-2,5-diphenyltetra-zolium bromide (MTT) cytotoxicity assay. The supernatants were assayed for insulin content by enzyme linked immunosorbent assay (ELISA). Reverse transcriptase-PCR assay and Western blotting were used to determine the expression of glucose transporter 2 (GLUT2) involved in insulin secretion. Cytosolic Ca2+, the trigger of insulin exocytosis, was analyzed with the fluorescent probe FURA-3/AM. Results RBP did no effect on the cell viability with a concentration of 10-8-10-12mol/L of 2 hours intervention. But it stimulated basal insulin secretion of RINm5F cells, accompanied by up-regulated increased expression of GLUT2 and elevated concentration of cytosolic Ca2+. Conclusion RBP could stimulate basal insulin secretion without affecting the cell viability.

OBJECTIVETo investigate the incidence, risk factors and preventative methods associated with chyle leak following complete mesocolic excision(CME) for colon cancer.

METHODSClinical data of 592 patients with colon cancer undergoing CME in the department of Colorectal Surgery in the Fujian Medical University Union Hospital from September 2000 to September 2011 were analyzed retrospectively.

RESULTSChyle leak occurred in 46 patients(7.7%). The incidence of postoperative chyle leak following right CME hemicolectomy was 13.3%(30/226), significantly higher than that after left CME hemicolectomy (4.4%). On univariate analysis, chyle leak following CME was associated with tumor size(P<0.05), tumor location(P<0.01), and lymph nodes harvested(P<0.01). Multivariate logistic regression revealed that tumor location and lymph nodes harvested were independent risk factors associated with chyle leak following CME(P<0.05).

CONCLUSIONSTumor location and lymph nodes harvested are independent risk factors for chyle leak following complete mesocolic excision for colon cancer. When the drainage output suddenly increases after oral intake resumption, the chyle test of ascitic fluid should be performed for early diagnosis and prompt management.

OBJECTIVETo examine HIV prevalence and its associated factors among men who have sex with men (MSM) and provide the evidence for the intervention program among MSM.

METHODSA face-to-face questionnaire interview was conducted among MSM recruited by snowball sampling method in Yuzhong, Jiulongpo and Shapingba district of Chongqing from July to September, 2007. Totally, 1044 MSM were recruited. Associated factors with HIV prevalence were analyzed using forward stepwise logistic regression that HIV status was the dependent variable and demographics, AIDS awareness, sexual behaviors and the status of the intervention were independent variables.

RESULTSA total of 1044 MSM were surveyed. The rate of AIDS awareness was 89.5% among MSM. The rate of unprotected anal sex during the past 6 months was 63.8%. The prevalence of HIV and syphilis was 8.5% (89/1044) and 12.5% (131/1044) respectively. The multivariate analysis identified that the older MSM (OR = 1.69, 95% CI: 1.13 - 2.52), junior school education (OR = 1.89, 95% CI: 1.17 - 3.05), younger than 18 years old of the first sex (OR = 3.11, 95% CI: 1.20 - 8.02), more than 10 sexual partners (OR = 2.24, 95% CI: 1.24 - 4.02), the history of having sex with women (OR = 2.40, 95% CI: 1.64 - 3.51) and syphilis infection (OR = 4.52, 95% CI: 2.77 - 7.38) were independent risk factors associated with HIV infection.

CONCLUSIONThe rate of unprotected anal sex was high, so were the prevalence of HIV and syphilis among MSM. It should be urgent to conduct the intervention to stop AIDS rapid transmission among MSM.
