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 To explore clinical value of the single-hale video-assisted thoracoscope surgery in lung surgery.Methods In our hospital from January 2015 to June 2015, a total of 60 patients was performed with lung partial resection line thoracoscope surgery, 28 routine puckering traditional video-assisted thoracoscope treatment, in the same period 32 underwent video-assisted thoracoscope surgery.Intraoperative blood loss, operating time, postoperative pain degree, and postoperative chest such as flow rate were compared between two groups.Results Two groups of patients had no perioperative death and severe complications.Intraoperative blood loss and operating time were no significant significance between single-and double-hole operation groups.The degree of postoperative pain score was (0.8 ± 0.5) in puckering thoracoscope group, and (1.2 ± 0.6) in traditional thoracoscope group, with significant difference (P =0.009).Conclusions Single-hole thoracoscope surgery in the treatment of lung diseases is feasible and reliable compared to traditional thoracoscope surgery, and patients can effectively reduce postoperative pain, and improve the quality of life.

Objective To compare the efficacy of lymph nodes(LNs) dissection between video-assisted thoracic surgery (VATS) and thoracotomy in the treatment of clinical stage Ⅰ lung cancer.Methods A comprehensive search of PubMed,Ovid Medline,EMBASE,Web of Science,ScienceDirect,the Cochrane Library,Scopus database and Google Scholar was performed to identify studies comparing VATS and thoracotomy in LNs dissection.The data was analyzed by RevMan 5.3 software and SPSS 18.0.Results After selection,23 articles met the inclusion criteria.2 316 patients were involved in VATS group and 3 346 patients were involved in Open group.Meta analysis showed that less total LNs(95％ CI:-1.64--0.60,P ＜ 0.0001),totalLNsstations(95％CI:-0.61--0.01,P=0.04) andN1 LNs(95％CI:-0.28--0.02,P=0.02)were dissected in VATS group.On the left side,more LNs were dissected in VATS group(95％ CI:0.51-3.22,P =0.007).The same number of mediastinal LNs (95％ CI:-0.74-0.15,P =0.20),mediastinal LNs stations (95％ CI:-0.20-0.14,P =0.76),right side LNs (95 ％ CI:-1.52-2.23,P =0.71) were harvested in both groups.Conclusion In the surgical treatment of clinical stage Ⅰ lung cancer,less total LNs,total LNs stations and N1 LNs were dissected in VATS group,while more left side LNs were harvested by VATS.The same number of mediastinal LNs,mediastinal LNs stations right side LNs were harvested in the two groups.This conclusion still needs to be further proved by more high-quality and large-scale RCTs.

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 To observe the safety and efficiency of SpO_2 -Allen's test in peri -puncture radial artery cannulation for invasive blood monitor. Methods 50 patients were selected for the radial artery cannulation in surgical intensive care unit(SICU). All of them were still sober. All of the patients were examined by SpO_2 -Allen's test and Allen's test before radial artery cannulation, 3 days after puncture and after pulling out the cannula. Resluts The results of Allen's test of 42 patients were negative,while those of 49 patients were negative in SpO_2 - Allen's test. Statistics difference existed between group of SpO_2 - Allen's text and group of Allen's text(P

Objective To investigate the effect of propofol and midazolam anesthesia in the treatment of persistent state of intractable epilepsy in children.Methods A total of fifty children with intractable epilepsy were selected in Guangzhou Women and Children''s Medical Center from May 2011 to May 2016,and were divided into propofol group and midazolam group according to the method of anesthesia,each group 25 cases.In the treatment,continuous EEG and ECG monitoring were applied in both groups,and the changes in hemodynamics were recorded in order to compare the medication and treatment effects.Results After epilepsy was under control and drug was withdrawn,the heart rate (HR),systolic pressure (SBP),diastolic pressure (DBP) of the two groups were all reduced,lower than the data collected before the treatment,the differences were statistically significant (P<0.05);in the propofol group,HR and SBP after control were (93.21±17.61) time/min and (92.44±12.84) mmHg (1 mmHg=0.133 kPa),lower than those of the midazolam group((109.84±18.41) time/min,(101.93±14.79) mmHg,t=3.264,2.423,P<0.05);the medication time,control time,intubation time of the propofol group were all shorter than those of the midazolam group ((13.21±2.14) h vs.(15.39±3.39) h,(3.47±0.89) min vs.(8.79±1.21) min,(2.03±0.79) d vs.(6.31±1.34) d,t=2.719,17.709,13.757,P<0.05);the total effective rate in the propofol group was significantly higher than that of the midazolam group (97.5%(39/40) vs.82.5%(33/40),χ2=5.357,P=0.021).Conclusion Propofol is effective in the treatment of persistent state of intractable epilepsy in children with good sedative effect,and can also reduce children''s resistance,therefore it''s worth promoting and applying into treatment.

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.

OBJECTIVETo establish an efficient and high resolution 2-DE (two-dimensional electrophoresis) protocol for root tuber proteome analysis of Rehmannia glutinosa.

METHODProteins from root tuber of R. glutinosa were extracted by using five different methods and their productivity and profiles were assessed by means of SDS-PAGE and two-dimensional electrophoresis.

RESULTThe trichloroacetic acid (TCA)-phenol extraction method was found most effective for the extraction with the highest protein yield, the most spots in protein patterns, and the highest resolution of proteins, and the clearest background could be achieved simultaneously. A 1:5 solution of ampholine pH 3-10 and pH 5-8 for a nonlinear gel and the 170 microg of protein loading dosage obtained maps with more protein spots and higher resolution of separation patterns.

CONCLUSIONThis study based on the optimized root tuber proteome preparation and the 2-DE protocol gets a high resolution and reproducibility 2-DE image, which will be expected to have excellent applications in proteomics studies of R. glutinosa tuber root.
