Nerve growth factor (NGF) has been the focus in area of angiogenesis.In differential,survival,development of nerves,NGF plays a crucial role.In addition,NGF activates migration,differential of endothelial cells and vascular smooth muscle cells,and stimulate the activation of the endothelial progenitor cells in angiogenesis.Crosstalk between vascular endothelial growth factor and NGF is also critical in the development of vessels.The function of NGF in angiogenesis blazes a trail in therapy of ischemia diseases.

Objective To analyze the variation of peripheral blood Th17 cells and Foxp3+CD4+CD25+regulatory T (Treg)cells in patients with ankylosing spondylitis (AS),and to interpret the role of the ratio imbalance of peripheral blood Th17/Treg cells in the pathogenesis of AS.Methods The percentage of peripheral blood Th17 cells and Foxp3 +CD4+CD25+ Treg cells in AS patients and healthy subjects were determined by flow cytometry (FCM).The concentrations of IL-2,IL-10,TGF-β,IL-6,IL-17 and IL-23 in the serum were measured by enzyme linked immunosorbent assay.The correlation between these cytokines and traditional parameters was analyzed.T test,ANOVA,SNK-q and Speannan's analysis were used for statistical analysis.Results Compared with healthy controls,the percentage of Th17 cells in AS patients increased significantly (P＜0.05); Compared with the inactive AS patients,the percentage of Th17 cells in active AS patients increased significantly [(2.10±0.82)％,(2.89±1.77)％,P＜0.05)]; the percentage of Foxp3+CD4+CD25+ Treg cells in active AS patients was markedly lower than healthy controls (P＜0.05).Compared with healthy controls and inactive AS patients,the specific value of Th17/Treg in active AS patients increased significantly(P＜0.05).The concentrations of IL-17 and IL-23 was found significantly higher in patients with AS than that in healthy controls (t=2.203,P=0.032 and t=2.088,P=0.041).The concentrations of IL-17 and IL-23 was found significantly higher in patients with active AS than that in inactive AS (t=2.808,P=0.008 and t=2.242,P=0.020).The correlation analysis revealed that these cytokines and traditional parameters was not relevant except IL-17/BASDAI (r=0.32,P=0.044).Conclusion The increased ratio of Th17 cells and decreased ratio of Foxp3+CD4+CD25+ Treg cells may play a critical role in AS progression.Manipulating the balance of Th17/Treg would provide a new approach for the treatment of AS.

Objective To investigate the possible mechanism of apoptosis effect induced by resveratrol in human acute T lymphoblast leukemia Molt-4 cells. Methods MTT method was used to analyze the inhibition rate. The cell cycle and apoptosis percentage of Molt-4 cells treated with resveratrol were detected by flow cytometry. The expression of WAVE1 mRNA was assessed by semi-quantitative RT-PCR. Results After treated with 12.5, 25.0, 50.0, 100.0, 200.0μmol/L resveratrol for 24, 48 and 72 hours, the inhibitory effects were at 29.32 %, 36.11 %, 53.92 %, 62.50 %, and 74.98 %, respectively. Resveratrol was able to inhibit the proliferation of Molt-4 cells in a time-dependent and dose-dependent manner (F =33.614, P <0.05).Compared with control group, after treated with 50.0, 100.0 μmol/L resveratrol for 48 h, the cell number in S phase of Molt-4 cells was 68.6 % and 78.1 %, respectively, and the cell cycle was arrested at S phase (F = 19.453, P < 0.01) after treated with 50.0, 100.0 μmol/L resveratrol for 48 h, the ratio of WAVE1/GAPDH was 0.356±0.03, 0.382±0.05. Compared with control group 0.586±0.06, the ratio of WAVE1/GAPDH was decreased (F =8.950, P <0.01). Conclusion Resveratrol could induce the cells to undergo apoptosis, which was probably related to downregulation the expression of WAVE1.

Objeetive To analyze the risk factors on anastomotic leakage after low anterior resection with the technique of total mesorectal excision(TME)for rectal carcinoma. Methods Our retrospective study included 498 patients of rectal cancer who underwent anterior resection with TME technique. Results 7.2%patients(36/498)developed clinical anastomotic leakage.Sex,distance of tumor from anal verge,preoperative radiotherapy were found related to the anastomotic leakage ( P＜0.05 or0.01),while age,diabetes,hypertensive disease,vesse]emboli,diversion stoma construction,anastomotic technique were not.Among the 37 patients with diversion stoma construction simultaneously,3 patients developed leakage who recovered conservatively.Among the other 33 leakages 10 were cured conservatively.The other 23 leakages necessitated a laparotomy and proximal colostomy. Conclusion Sex,distance of tumor from anal verge,preoperative radiotherapy were risk factors for anastomotic leakage after TME.

Objective: To investigate the effect of Bortezomib (an inhibitor of proteasome) on IL-6 synthesis and cachexia in colon 26 tumor bearing mice. Methods: Murine colon 26 adenocarcinoma cells were inoculated subcutaneously in male BALB/c mice to induce cachexia. Saline and three doses of Bortezomib (0.1, 0.5 and 1.0 mg/kg) were given intraperitoneally on day 6, 9, 12 and 15 after tumor inoculation and mice were sacrificed on day 16. Body weight, food intake and tumor volume were monitored daily. Serum levels of IL-6 and IL-10, tumor tissue levels of IL-6 and activity of NF-κB in tumor tissues were investigated in all animals. Results: By day 16, saline treated tumor-bearing mice showed significant body weight and carcass weight changes (P<0.01), gastrocnemius muscle wasting and epididymal fat depletion (P<0.01). Furthermore, Tumor-bearing caused a significant increase of IL-6 and IL-10 (P<0.01) in serum and IL-6 in tumor tissues. Administration of Bortezomib attenuated the wasting of carcass weight, gastrocnemius muscle and epididymal fat. Bortezomib dose dependently inhibited the NF-κB activation and IL-6 synthesis of the tumor cells, and the maximal inhibition was observed at the dose of 1.0 mg/kg (P<0.01). Bortezomib 0.5 mg/kg significantly inhibited the increase of serum IL-6 (P<0.01). Bortezomib showed significant anti-tumor effect, and tumor growth was significantly inhibited by Bortezomib with 0.5 and 1.0 mg/kg (P<0.01). Conclusion: Bortezomib can inhibit NF-κB activation, tissue wasting and cancer cachexia.

Objective To evaluate the efficacy of total glucosides of paeony(TGP) in the treatment of undifferentiated spondyloarthropathies(uSpA) and investigate its mechanism.Methods One hundred and sixteen cases of uSpA were randomly assigned to 2 groups,one group was treated with TGP and diclofenac sodium,the other group with SASP and diclofenac sodium.The efficacy and side effects of the two groups were compared after 12 weeks treatment.The level of IL-6,IL-10 and TNF-? was determined at the same time.Result After 12 weeks treatment,the major clinical manifest and the indexes of disease activity were no difference of statistical significance in the two groups.The incidence of parenterally side effects was 8.6% in TGP group,and 25.9% in SASP group.There was difference at statistical significance between the two groups(? 2 =6.042,P=0.014).Before treatment,the level of IL-6,IL-10 and TNF-? in the serum of two groups were no statistical difference,while there was obviously difference after 12 weeks treatment(t= 2.672,2.483 and 2.088,P=0.009,0.014 and 0.039).Conclusion The efficacy of TGP and SASP has no significant difference in the treatment of uSpA.But the incidence of parenterally side effects in the TGP group was less than SASP group.The mechanism of efficacy of TGP may be related to inhibiting the production of IL-6,IL-10 and TNF-?.
