Objective: To compare the efifcacy and safety of circumferential pulmonary vein antecourt isolation (CPVAI) ablation and stepwise linear (SL) ablation in treating the patients with atrial ifbrillation (AF) Methods: A total of 136 AF patients with catheter ablation under EnSite 3000 guidance in our hospital were retrospectively summarized. The patients included 93 paroxysmal AF and 43 persistent AF and divided into 4 groups. Paroxysmal AF with CPVAI ablation,n=45, Paroxysmal AF with SL ablation,n=48 and persistent AF with CPVAI ablation, n=18, persistent AF with SL ablation,n=25. The differences of left atrium diameter, ablation time, X-ray exposure time, the success rate and complication were compared among different groups. Results: For 12 months follow-up study, the success rate and complication were similar between 2 ablation methods for treating both Paroxysmal AF and persistent AF patients. For Paroxysmal AF patients, both ablation methods could effectively reduce left atrium diameter,P<0.01. The SL ablation had less procedural time than CPVAI ablation,P<0.01, while the X-ray exposure time was similar between 2 ablation methods. Conclusion: Both CPVAI and SL ablation methods were effective and safe for treating AF patients.

Objective To investigate the effects of initiating oral-medication and insulin-treatment to residual islet function in adult patients with latent autoimmune diabetes in adults (LADA).Methods Fifty nice inpatients and 11 outpatients of LADA were enrolled from the Peking Union Medical College Hospital from January 1981 to October 2014,including 34 cases with initiating insulin therapy and 36 cases with initiating oral medication.Patients were followed up at least twice and with a 6-month interval.The age,body mass index (BMI),diagnosis time,fasting C peptide (FCP),2-hour postprandial C peptide (2 hCP),glycosylated hemoglobin (HbA1c) were compared between two groups.Results The age of disease onset in insulin-treatment group was significantly lower than that in oral-medication group (t =2.049,P =0.045).The proportion of patients complicated with other autoimmune diseases in oralmedication group were higher than that in insulin-treatment group [24％ (8/34) vs.47％ (17/36),x2=4.275,P=0.039].The FCP and 2 hCP in insulin-treatment group were significantly higher than those in oral-medication group [FCP:0.25 (0.00-0.80) vs.0.00 (0.00-0.60) μg/L,Z =3.498,P =0.030,2 hCP:0.42(0.02-1.20) vs.0.14(0.02-0.19) μg/L,Z =3.235,P=0.001] on 6 month after treatment;however,there were no significant differences on 6-12 months,13-36 months or 37-60 months after treatment between two groups.No antibody negative conversion was detected in 10 inpatients,who were reexamined with glutamic acid decarboxylase antibody (GADA) more than twice.The detection rate of diabetes retinopathy was 4％ (1/26) in insulin-treatment group and 28％ (8/29) in oralmedication group (x2 =6.179,P =0.013).Conclusion Initiating insulin therapy at first diagnosis of LADA can protect the residual islet function,and may reduce the rate of diabetic retinopathy.

Objective:To analyze KCNJ5 mutation of adenomas in patients with aldosterone-producing adenoma (APA) companying with hypokalemia, and to compare the clinical characteristics of patients with and without KCNJ 5 mutations.Methods:Clinical data of 144 APA patients were retrospectively analyzed. DNA were extracted from adenoma tissues, and amplified and sequenced for KCNJ5 gene. The serum potassium level and cardiac complications in patients with and without KCNJ5 gene mutation were compared.Results:Among 144 tumors, 131 tumors (91%) had KCNJ5 mutation, including 68 tumors with G151R, 56 tumors with L168R, 5 tumors with E145Q, and two tumors with novel mutations, V156_K160delITE and G151delinsVR. Compared with patients without KCNJ5 mutation, patients with KCNJ5 mutation had lower preoperative serum potassium levels, more cardiac complications, lower postoperative systolic blood pressure, and better postoperative hypertension relief. There were no statistical differences in age, gender, blood pressure, serum potassium level, plasma renin activity or plasma aldosterone concertration.Conclusion:91% adenomas in patients with APA and hypokalemia had KCNJ5 mutation, suggesting that KCNJ5 mutation is the main cause in these patients.

Chronic joint pain due to loss of cartilage function, degradation of subchondral bone, and related conditions are common plights of an arthritis patient.Antioxidant compounds could solve the problems in arthritic condition. The objective of this study was to evaluate the anti-arthritic activity of D-carvone against complete Freund’s adjuvant (CFA)-induced arthritis in rats. D-carvone was orally administered for 25 days at the doses of 30 and 60 mg/kg against CFA-induced arthritic rats. Changes in body weight, paw swelling, organ index, hematological parameters, oxidative stress markers, inflammatory cytokines, and histopathology were recorded.Oral treatment of D-carvone significantly improved the body weight, reduced the paw swelling, edema formation, and organ index in arthritic rats. The levels of white blood cells were reduced, red blood cells and hemoglobin levels were improved in D-carvone treated arthritic rats. Lipid peroxidation levels were lowered whereas enzymatic and non-enzymatic antioxidants were significantly elevated by D-carvone administration against arthritic rats. D-carvone significantly modulated inflammatory cytokine levels and improved the ankle joint pathology against CFA-induced arthritic inflammation. In conclusion, D-carvone proved significant anti-arthritic activity against CFA-induced arthritis in rats.
