Objective To explore the clinical effect of the improved operation of endoscopic thoracic sympathectomy(ETS)for treatment of palmar hyperhidrosis.Methods The improved operation of ETS was used to 105 patients with palmar hyperhidrosis.T3 sympathetic was blocked in 105 cases with palmar hyperhidrosis.Results Hand sweating disappeared and axillary sweating discreased significantly in all patients.No one had any serious complications such as bleeding and Horner Syndrome except for five patients with pneumothoraces.Compensatory sweating was found in 15 patients following up from 1~12 months after operation.Conclusion The improved operation of ETS is a simple,safe,effective and less complications procedures.

Objective To sensitize the T-cell in the peripheral blood of the active tuberculosis pa-tients by rCFP-10/ESAT-6 fusion protein, phytohaemaggiutinin(PHA) and physiologic saline, and to detect the IFN-γ to approach the significance of the tuberculosis infection. Methods One hundred and eleven pa-tients were diagnosed by clinical definite, 292 undergraduate students were chosen by X-ray and PPD-selec-fion as volunteers. 3.0 ml of blood was taken from each volunteer, rCFP-IO/ESAT-6, PHA and physiologic saline were added into each 1.0 ml, respectively. The A valule and antibody of IFN-γ were assayed by ELISA. Results Treated with rCFP-10/ESAT-6 group: the A value average of patients group was 1. 3885±0.6236, students group was 0.2944±0.0917. Intergroup t'=16.4259, P<0.05, set>0.42 as cut-off, the positive rate of patients group was 93.58%, students group was 13.07%. Treated with PHA group: the A value average of patients group was 1.2463±0.5541, of which the other was 0.5613±0.064, t'=19.1797,P<0.05. Treated with physiologic saline group:the A value average of patients group was 0.0772±0.0444,of which the other was 0.0290±0.0235,t'=13.9487,P<0.05. All had significant deviation. The antibody positive rate of the patients group was 66.36%, the students group was 7.19%. Conclusion rCFP-10/ESAT-6 as specific antigen, the sensitivity of IFN-γ release assay by ELISA is above 90%. No matter specific or non-specific disposal, the active tuberculosis patients have higher IFN-γ, release level and antibody than the control group.

Objective To profile the phenotype and pathogens of cutaneous and mucous mycoses in a dermatology outpatient clinic in Nanchang region. Methods A review was performed to assess cutaneous and mucous mycoses diagnosed in the dermatology outpatient clinic of Dermatology Hospital of Jiangxi Province from 2006 to 2008. The relationship of clinical phenotype and pathogens to season, patients' age and gender was analyzed. Results A total of 7251 cases were collected, and the ratio of male to female patients was 2.3: 1. The most prevalent mycoses included tinea cruris (2702, 37.1%), pityriasis versicolor (1505, 20.8%) and tinea manus (727, 10.0%). In total, 4953 fungal strains were isolated from all the patients except for those with pityriasis versicolor, of them, Trichophyton rubrum accounted to 69.9%, Candida to 20.4%, and Trichophyton violaceum to 4.5%. Season, patients' age and gender were found to be associated with clinical phenotypes and pathogens of mycoses. Conclusions In the dermatology outpatient clinic of Nanchang region, tinea cruris is the most common superficial fungal disease, with the predominant pathogen being Trichophyton rubrum. Trichophyton violaceum is the primary pathogen of tinea capitis, which is different from other reports.

ObjectiveTo investigate the efficacy and toxicity of postoperative radiochemotherapy compared with chemotherapy alone in the treatment of locally advanced gastric cancer.MethodsA total of 83 patients with resected adenocarcinoma of the stomach were randomly assigned to postoperative radiochemotherapy group (RCT) ( n =43 ) or chemotherapy alone group (CT) ( n =40 ).Patients in RCT group received radiotherapy concurrent with capecitabine chemotherapy then followed by 4 - 6 cycles of FOLFOX4 chemotherapy.The total dose of radiation was 45 Gy.The dose of capecitabine was 1600 mg/m2per day.In the CT group,patients received 6 - 8 cycles FOLFOX4 chemotherapy.Survival was analyzed using Kaplan-Meier method and Logrank test. Results The follow-up rate was 96％. The number of patients who had a minimum of 2-,3-year follow-up time were 37,12 in the RCT group and 31,10 in the CT group.The 1-,2-,3-year local control rates for RCT and CT groups were 100％,97％,94％ and 95％,87％,73％ (x2 =4.54,P =0.033),respectively.The 1-,2-,3-year survival rates were 98％,86％,81％ in the RCT group,with 93％,80％,64％ in the CT group ( x2 =3.96,P =0.047 ).The incidence of grade 3hematological toxicity in the RCT and CT group was 23％ vs 15％ ( x2 =0.93,P =0.630 ),and grade 3gastrointestinal toxicity was 16％ vs 10％ ( x2 =0.95,P =0.624 ). Conclusions Compared with chemotherapy alone,postoperative radiochemotherapy can improve survival of locally advanced gastric cancer patients with acceptable toxicities.

This study aimed to establish human IFN-gamma (hIFN-gamma) in vitro release assay and to apply it in diagnosis of human tuberculosis. Human IFN-gamma gene was cloned and expressed in Escherichia coli. The recombinant hIFN-gamma was purified and used as immunogen to immunize mice and rabbits respectively. Monoclonal and polyclonal antibodies were respectively developed and a sandwich ELISA was established. The heparized whole blood from 111 active tuberculosis patients and 292 clinical healthy controls were collected. The blood was stimulated with tuberculosis specific fused antigen ESAT-6/CFP-10 and the plasma was collected for IFN-gamma detection. The sensitivity for tuberculosis diagnosis was 95.5%, whereas the positive detection rate for the healthy controls was 16.7%. There was a significant difference between the patients and healthy controls (P<0.01) indicating that this assay had a high sensitivity and specificity, and thus could be promising in tuberculosis diagnosis.

Objective To explore the clinical characteristics and risk factors of catheterrelated infection in continuous renal replacement therapy (CRRT) patients.Methods The demographic and clinical data of CRRT patients who inserted with double-lumen non-cuffed dialysis catheter at the First Affiliated Hospital of Sun Yat-sen University from January 1,2016 to December 31,2016 were collected.According to the presence or absence of catheter-related infections,they were divided into infected group and uninfected group.Statistics and analysis of the incidence and pathogenic characteristics of catheter-related infections;Comparison of clinical features of infected and uninfected groups;A multivariate Cox proportional hazard model was used to analyze risk factors for catheter-related infections.Results A total of 364 patients with CRRT (437 cases of central venous catheterization) were enrolled in the study.Catheter-related bloodstream infection (CRBSI) and catheterrelated colonization (CRCOL) rates were 3.565 and 2.228 events per 1000 catheter-days.These catheters were associated with higher proportion of inserted in ICU (P=0.007),immunosuppression (P=0.002),receive catecholamine inotropes therapy (P=0.001) and shock (P=0.030).The infection catheters also had shorter indwelling time (P=0.032) and lower level of blood hemoglobin (P=0.017),serum creatinine (P=0.004),blood brain natriuretic peptide (P=0.005) pericatheter use.The most common pathogens were Gram-negative bacteria,especially Acinetobacter baumannii,which caused 37.5％ CRBSI and 20.0％ CRCOL.Multivariate Cox regression model showed female (P=0.029,HR=2.151),diabetes (P=0.016,HR=2.807),receive catecholamine inotropes therapy (P=0.012,HR=2.655),immunosuppression (P=0.037,HR=2.203) were independent risk factors associated with catheterrelated infection.Conclusions The incidence of CRBSI and CRCOL is 3.565 and 2.228 events per 1000 catheter-days CRRT patients in our hospital.The most common pathogen of catherter-related infection is Gram-negative bacteria.Female,diabetes,received catecholamine inotropic drugs,and immunosuppression were independent risk factors associated with catheter-related infection.
