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.

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 evaluate the technical success,adverse events in 30 days after endovascular repair for acute and non-acute Stanford B aortic dissection.Methods A search was performed to identify all Chinese literatures that compare the effect of TEVAR on acute and non-acute Stanford B dissection in WanFang and Chinese National Knowledge Infrastructure (CNKI) from 2009 to 2014.Literatures were extracted and x2 test conducted by SPSS 17.0 software,REVMAN 5.3 software was used to conduct meta-analysis and bias analysis by STATA software.Results 5 studies including 468 patients (acute group 243,non-acute group 225) were extracted.Acute Stanford B dissection have higher rate both in total complications(OR =3.10,95％ CI =[1.74,5.53],P =0.0001) and endoleaks (OR =2.07,95％ CI =[1.11,3.88],P =0.02) within 30 days than non-acute group,the technique success rate (P =0.3),the mortality rate within 30 days (P =0.27) as well as aortic related mortality rate (P =0.26)show no significant difference.Conclusion Acute Stanford B dissection have higher rate of total postoperative complications,endoleaks within 30 days than non-acute group,with similar surgical success rate,30 days mortality rate and aorta related mortality rate.

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.

Objective To sum up the experiences of tongue repair after radical operation of tongue carcinoma with free forearm flap in the last two years. Methods The clinical data of 26 patients underwent forearm free flap transfer for tongue repair from February 2002 to February 2004 were retrospectively analysed . Results Among the 26 grafted forearm flaps, 25 survived. Only one flap occurred arterial thrombosis and necrosis after the second operation.All the patients were followed up for 6 months to 2 years. Reconstruction tongues had suitable volume and shape as well as perfect movement ability. Conclusion Free forearm flap was suitable to repair the tongue defect after radical operation of tongue caicinoma. The rate of operation success was high, and reconstructed tongues could basically meet patient's normal life.

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.

ObjectiveTo understand the clinical characteristics and therapy of Huntington's disease (HD).MethodsThe clinical characteristics of five typical kindreds with HD were analysed. The therapeutic progression after reviewing literature was summarized.ResultsFive kindreds inherited in an autosomal dominant manner. They were all adult-onset HD.Progressive motor dysfunction,cognitive decline,emotional and behavioral disturbance were the key clinical presentations. At an early stage, manifestations include subtle emotional symptoms and involuntary movements.The reason of visiting doctor was chorea. CT scans demonstrated brain atrophy.ConclusionsTypical clinical manifestation and clear family history may be enough to make primary diagnosis. Psychological evaluation at risk individual may help to diagnose early. Gene testing may confirm the diagnosis of HD. The drugs and occupational,physical therapy and psychotherapy for HD patients can help maintain the highest level of function and improve the quality of life.

Objective To evaluate the therapeutic effect of single-session repetitive transcranial magnetic stimulation(rTMS) on motor function in Parkinson's disease(PD).Methods Twenty-four PD patients were enrolled into this two-stage study with cross-over design and divided into two groups randomly.The subjects of first group underwent therapeutic rTMS(0.5 Hz,80% of resting motor threshold,1 000 pulses×2,single-session) on primary motor cortex and underwent controlled rTMS with same stimulation parameters on occipital cortex seven days later.The subjects of second group underwent controlled two sessions of rTMS in reverse sequence.The motor function was assessed by Unified Parkinson's Disease Rating Scale(UPDRS) and Visual Analogy Scales.Results The UPDRS improvement(34.2±7.5%,36.5±8.7%) of subjects after therapeutic rTMS on primary motor cortex was significant higher than that(7.2±3.1%,7.4±3.8%) after controlled rTMS on occipital cortex(P<0.01).The duration of therapeutic effect(39±12 minutes,35±11 minutes) was significant higher than that of controlled rTMS.Conclusion The single-session rTMS has therapeutic effect of short duration on motor performance in PD.
