Objective To compare the therapeutic efficacy between warm needling and Pyridostigmine bromide in treating ocular myasthenia gravis, for seeking the optimal treatment method. Method Seventy patients with ocular myasthenia gravis were randomized into a treatment group intervened by warm needling and control group intervened by Pyridostingmine bromide, 35 in each group; meanwhile, fortified Yi Qi Tang decoction was given to both groups. The observation lasted 6 weeks and a 3-month follow-up was conducted. The clinical absolute and relative scoring system for myasthenia gravis, and the Chinese medicine syndrome scale for spleen-qi deficiency were adopted for quantitative comparison and efficacy evaluation. Result The total effective rate was 85.7% in the treatment group, higher than that in the control group. Conclusion Warm needling plus herbal medicine is effective in treating ocular myasthenia gravis.

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.
