Prevalence of metabolic syndrome in patients with psoriasis: a cross-sectional study in Singapore

INTRODUCTIONPsoriasis is a chronic inflammatory condition that affects the skin and joints, and is associated with cardiovascular risk factors, including metabolic syndrome (MetS). We aimed to assess the prevalence of MetS in patients with psoriasis and determine whether there was a correlation between psoriasis severity and MetS in a Singapore population.METHODSThis was a cross-sectional study of patients with psoriasis, aged 18–69 years, who attended a tertiary dermatology referral centre in Singapore from October 2007 to February 2009. Fasting glucose, lipids, blood pressure, Psoriasis Area and Severity Index, and body mass index were measured. MetS was diagnosed in the presence of three or more criteria of the modified National Cholesterol Education Program Adult Treatment Panel III.RESULTSAmong 338 patients with psoriasis, there were 238 (70.4%) men and 100 (29.6%) women, who were Chinese (n = 228; 67.5%), Malay (n = 52; 15.4%) and Indian (n = 58; 17.2%). The prevalence of MetS was 45.1%. MetS was 44% more prevalent in patients older than 50 years (p = 0.02). Malay patients with psoriasis were significantly more likely to have hypertriglyceridaemia, elevated fasting plasma glucose and abdominal obesity. There was no significant correlation between psoriasis severity and risk of MetS.CONCLUSIONThe prevalence of MetS in patients with psoriasis in Singapore was 45.1%, or nearly threefold higher than the Singapore general population. Patients with psoriasis should be screened yearly for MetS and any modifiable cardiovascular risk factors should be actively controlled.     

基于医院信息系统的乳腺癌临床特征及中西医用药特征分析

目的 解析真实世界中乳腺恶性肿瘤患者的人群特征、诊断特征、中西医用药特征，为乳腺癌的临床防治提供参考。方法 采集2002年2月至2015年5月全国60家三级甲等医 院信息系统（Hospital Information System，HIS）中，出院诊断为“乳腺癌”的患者用药信息，采用SAS9.3统计软件，对人口学信息、诊断信息、医嘱用药信息等进行描述性分析。结果 39798例乳腺癌患者，平均年龄（50.93者，平均年龄）岁；多以门诊入院，入院病情以“一般”为主;合并疾病主要为高血压，骨肿瘤，联用西药以抑制肿瘤细胞增殖、治疗并发症、缓解放化疗不良反应为主；中医辨证以痰瘀互结证，气阴两虚证，肝气淤滞证，脾气亏虚证型最为常见，临床清热解毒剂、益气扶正剂，活血化瘀剂应用较多。结论 乳腺癌中西医结合治疗，联用药物广泛，临床治疗基本符合临床指南。     

胃粘膜相关淋巴组织型淋巴瘤MAPK和Stat3磷酸化及cyclinD1蛋白表达的意义

目的:研究胃粘膜相关淋巴组织型(MALT)淋巴瘤MAPK和Stat3磷酸化与cyclinD1蛋白表达及其意义。方法:利用免疫组织化学方法检测了45例胃MALT淋巴瘤MAPK和Stat3磷酸化及cyclinD1蛋白的表达。结果:在胃MALT淋巴瘤中p-MAPK、p-Stat3及cyclinD1蛋白的阳性率分别为73.3%(33/45)、64.4%(29/45)和68.9%(31/45);低度恶性组p-MAPK和cyclinD1蛋白的阳性表达强度明显高于高度恶性组(P<0.01),而p-Stat3表达强度无明显差异(P>0.05);在低度和高度恶性胃MALT淋巴瘤中p-MAPK和cyclinD1蛋白的阳性信号强度均呈明显的正相关(r=0.6572和0.6823,P<0.01),而p-Stat3与cyclinD1蛋白表达未见明显相关性(r=0.1927,P>0.05)。结论:提示MAPK磷酸化在胃MALT淋巴瘤中发生及演进过程中起重要作用,但Stat3的磷酸化可能与该肿瘤的恶性演进关系不明显;在胃MALT淋巴瘤的发生与发展中,p-MAPK可诱导cyclinD1过度表达,从而促使该肿瘤细胞维持高增殖状态。     

人原发性肝癌中p16基因表达及CpG岛甲基化状态的研究

目的　进一步探讨人原发性肝癌中 p16基因 m RNA转录水平变化与其基因启动子区 Cp G岛甲基化的关系 ,及其在肝癌发生中的意义。方法　采用狭缝印迹杂交检测 2 0例人原发性肝癌及相应的癌旁、远癌组织及 2例正常人肝组织中 p16基因 m RNA表达水平 ,以甲基化特异性 PCR分析各组织中 p16基因启动子区 Cp G岛的甲基化状况 ,并进行统计分析。结果　 2 0例人原发性肝癌中 14例 (70 % ) p16 m RNA水平比远癌组织显著降低 ;13例 (6 5 % )显示 p16基因启动子区 Cp G岛甲基化 ,其中 84 .6 % (11例 )伴 p16 m RNA转录水平降低。结论　人原发性肝癌中存在高频率的 p16基因表达失活 ,其主要机制可能是启动子区 Cp G岛甲基化抑制了基因的转录 ,在人原发性肝癌的发生发展中有重要作用。其临床诊断和治疗意义有待进一步深入研究。     

出血性脑梗死危险因素的Logistic回归分析

目的探讨出血性脑梗死的危险因素。方法根据专业知识确定与出血性脑梗死有关的因素,采用非条件Logistic回归确定危险因素。结果大面积梗死灶、使用抗凝剂或溶栓治疗、糖尿病史是出血性脑梗死的独立危险因素,与年龄、高血压史、高血脂关系不大。结论大面积脑梗死、使用抗凝剂或溶栓、糖尿病患者发生梗死后出血的几率增大,及时行影像学检查可以早期发现。

Renal Transplantation in Patients With Pre-Transplant Donor-Specific Antibodies and Negative Flow Cytometry Crossmatches

The clinical significance of pre-transplant donor-specific antibodies (DSA), despite negative cytotoxicity and flow cytometry crossmatches (FCXMs), is unknown. We performed a retrospective cohort study of 60 living donor renal transplant recipients, all with pre-transplant cytotoxicity and T-cell and B-cell FCXMs that were negative. Twenty recipients had pre-transplant DSA detected by enzyme-linked immunosorbent assays (ELISA) and/or microbead methods. Forty contemporaneous DSA-negative controls were selected. In the DSA-positive group, after a median follow-up of 8.2 months (25-75% range, 5.4-22.8 months), patient survival was 100% and allograft survival was 95.0%. Acute humoral rejection (AHR) developed in four patients (20.0%). Three of the AHR episodes occurred within the first month post-transplant. Median serum creatinine at last follow-up was 1.3 mg/dL (25-75% range, 1.0-1.6 mg/dL), versus 1.1 mg/dL (25-75% range, 0.9-1.4 mg/dL) in the DSA-negative controls (p = 0.29). Only one of the 40 controls developed AHR (2.5%). Pre-transplant DSA was associated with a significantly increased incidence of AHR (p = 0.02 by log-rank test). In conclusion, despite negative pre-transplant cytotoxicity and FCXMs, renal transplant recipients with pre-transplant DSA detected by solid-phase methods may have an increased incidence of AHR and require close monitoring post-transplant.     

The changes of the interspace angle after anterior correction and instrumentation in adolescent idiopathic scoliosis patients

Background  

In idiopathic scoliosis patients, after anterior spinal fusion and instrumentation, the discs (interspace angle) between the lowest instrumented vertebra (LIV) and the next caudal vertebra became more wedged. We reviewed these patients and analyzed the changes of the angle.     

CLINICAL EXPERIENCE WITH LEVONORGESTREL AND ETHINYL ESTRADIOL IN BEIJING

A combination of levonorgestrel 0.15mg and ethinyl estradiol 0.03mg, an ultra-low dose oral con traceptive in pellet form, was tried out in 9 Beijing clinics. A total of l,035 healthy women of reproduc tive age participated in 9,413 cycles of treatment. Only one pregnancy was attributed to medication failure which resulted in a corrected Pearl index of 0.13/100 women-year. The incidence of breakthrough bleeding and amenorrhea was 0.12% and 0.05% res pectively. Using the life-table method, the net cumulative rate of termination due to medical-related reasons at one year was only 5.93/100 women. The incidence of side effects was low. The most frequent complaints were nausea and drowsiness, which re duced with the increase of treatment cycles. Some metabolic changes were studied. In comparison with other OCs used in China, this formula has the advantages of ultra-low-dose steroids with higher contraceptive efficacy, better cycle control and fewer side effects.
