Objective To evaluate video-assisted thoracoscopic sympathectomy(VTS) for the treatment of palmar hyperhidrosis(PH),and to analyze curative efficacies for surgeries on different sympathetic segments.Methods Medline search was done on PubMed and data of randomized controlled trials(RCTs) about comparisons of surgeries on different segments over the past decade were collected.According to the inclusion criterion,relevant articles were screened.Then we extracted data,assessed trail quality,and performed Meta-analysis by using RevMan 5.2 with postoperative compensatory hyperhidrosis(CH) as the main evaluation index.Results A total of 11 RCTs involving 1 413 patients were included,among which all patients underwent bilateral VTS.Ef cacious rates were similar between multiple and single ganglia sympathectomy(97.7% vs 98.8%,P <0.01).However,single-ganglia group showed a lower risk of CH compared to multiple-ganglia group.Meta-analysis suggested that,in the subgroups of the single-ganglia VTS,no significant difference was found between T2/T3 and other segments in the risk of CH [T2 segment vs other segments,RR =1.11,95 % CI(0.99,1.24) ; T3 segment vs other segments,RR =0.99,95% CI(0.89,1.11)].The risk of CH was significantly lower in T4 sympathectomy than in other segments [RR =0.67,95% CI(0.57,0.79)].By comparison of T2,T3 and T4 sympathectomy,we found that low segment had a lower risk of CH than high segment[RR =0.75,95% CI(0.68,0.84)].Conclusion Single-ganglia and low segment sympathectomy can significantly reduce the incidence of CH,and T4 is supposed to be the best segment for the treatment of PH.

Objective Based the previous studies, the present study was performed to investigate the antagonistic effects of different doses of Astragaloside IV on the immune function of Treg mediated by HMGB1 in vitro and its potential mechanism.Methods CD4+CD25-T cells isolated from the spleens of male BABL/c mice by magnetic beads were seeded on 48-well cell culture plates and were randomly divided into four groups as follows(12 holes per group). Normal control group: CD4+CD25-T cells were cultured merely. Treg group: Tregs(100μl) and CD4+CD25-T cells were co-cultured in ratio of 1:10. HMGB1+Treg group: Tregs(100μl) stimulated by HMGB1(1μg/ml) for 72 h and CD4+CD25-T cells were co-cultured in ratio of 1∶10. HMGB1+AST IV+Treg group: Tregs(100μl) stimulated by HMGB1(1μg/ml) and AST IV(100μg/ml)for 72 h were co-cultured with CD4+CD25-T cells in ratio of 1:10. CD4+CD25-T cells and supernatants were again collected on post-culture 72 hour. The proliferation of CD4+CD25- T cells was analyzed by MTT test, the activity of NFAT and the contents of cytokines of IL-2 released into supernatants were also determined by means of ELISA. Results When CD4+CD25-T cells were co-cultured with Tregs, the cell proliferation(0.166±0.039) and the levels of NFAT(0.156±0.035) and IL-2(2.38±0.58) in supernatant were markedly decreased as compared with those in the control group(P<0.01). However, the contrary results were found when CD4+CD25-T cells were co-cultured with Treg stimulated by HMGB1. Compared with those in the(HMGB1+Treg) group, the contrary results were showed with a dose-dependent in the(HMGB1+ASTⅣ+Treg) group.Conclusion ASTⅣcan rivalry the effects of HMGB1 on immune function of Treg in vitro, this result indicate that ASTⅣhas the therapeutic action on inflammation promoted by HMGB1.

Objective To evaluate the renal protective effect of targeted abdominal perfusion pressure (APP) treatment in intra-abdominal hypertension (IAH) and further investigate its related mechanisms.Methods Twelve healthy pigs were randomly divided into experimental group and control group,each group had 6 pigs.All animals were collected urine volume each hour,continuously monitored mean arterial pressure (MAP) and renal cortical blood flow after anesthesia.IAH models were established by intraperitoneally injecting carbon dioxide in all animals,the baseline MAP,intra-abdominal pressure (IAP)and APP were obtained before IAH models established.In both groups,IAP was raised gradually from 0 mm Hg to 10 mm Hg,20 mm Hg and 30 mm Hg.In control group,IAP was maintained at 30 mm Hg for 8 hours with-out any other interventions.In experimental group,the animals were intravenously given with norepinephrine in order to get a target level of APP equal to its baseline values after 15 minutes of the onset of 30 mm Hg IAP.Changes of renal cortical blood flow,serum creatinine,TNF-α,IL-6 and urine IL-18 with the alteration of IAP in both groups were explored.Animals were then sacrificed for renal histopathology after 8 hours of the onset of 30 mm Hg IAP.Results With the increase of IAP,renal cortical blood flow in both groups was significantly decreased (P < 0.01).Compared to its baseline,serum Cr and urinary IL-18 were significantly up-regulated after the maintenance of IAP at 30 mm Hg for 6 hours in both groups (P < 0.05).However,in experimental group,which utilized a strategy of targeted APP,significant improvement of the renal cortical blood flow was observed (P < 0.01),and urinary IL-18 was significantly lower than the control group (P < 0.05).Renal histopathological examination found no obvious abnormalities either in control group or in experimental group.Conclusions The targeted APP treatment may have some renal protective function within the first 8 hours of IAH by improving renal cortical blood flow rather than affecting systemic inflammatory response.

Objective Toinvestigatetheoperativeeffectandsafetyofendovascularstentingfor thetreatmentofsymptomaticvertebralarteryostialstenosis.Methods Fortypatientswithsymptomatic vertebral artery ostial stenosis and stenosis rate ≥70% were admitted to the Department of Neurology, China-Japan Friendship Hospital from November 2010 to January 2013 were enrolled retrospectively. All patients received endovascular stenting therapy,15 of them were implanted bare metal stents,and 25 were implanted drug eluting stents. The technical successful rate of operation,perioperation complications,and symptom remission rate of the patients were analyzed. At the same time,stroke and death incident as well as the related ischemic symptoms of the stent vascular feeding area in the follow-up period (13 to 36 months)wereobservedandtherestenosisratewasdocumented.Results Atotalof42stentswereimplanted in 40 patients,and the technical success rate was 100. 0%. The preoperative stenosis rate of vertebral artery ostial stenosis was 75% to 99%(mean 85 ± 7%);the postoperative stenosis rate was 0% to 20%(mean 6 ± 4%). There was no perioperative complication. The clinical symptoms of 19 patients disappeared completely,16 were improved significantly within the follow-up period,and the symptom remission rate was 87. 5%. No stent vascular feeding area related stroke and death occurred. Four patients had transient ischemic attack in posterior circulation,13 had restenosis after procedure (10 of them with bare mental stents and 3 with drug eluting stents). There was significant difference in restenosis rate between the bare mental stents andthedrugelutingstents(10/15vs3/25,P=0.001).Conclusion Endovascularstentingforthe treatment of the severe symptomatic vertebral artery ostial stenosis is a safe and efficient method. Although its restenosis rate is high,but it can improve the symptom of posterior circulation ischemia effectively.
