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。     

白芷酒炖前后挥发性成分的HS-SPME-GC-MS分析

目的探讨白芷酒炖前后对挥发性成分的影响。方法采用顶空固相微萃取技术(HS-SPME)结合气相色谱-质谱法(GC-MS)对白芷酒炖前后挥发性成分及其相对百分含量进行对比分析。结果从白芷生品中初步检测出53个峰,鉴定出36个成分;从白芷酒炖中检测出32个峰,鉴定出26个成分;与生品成分比较,酒炖白芷中有22种成分未测到,但新增了12种成分,表明酒炖白芷中的挥发性成分的组成和含量均发生了变化。结论白芷酒炖后由于受热及辅料黄酒的作用使挥发性成分的种类及含量发生了明显变化,并存在成分转化,本研究为白芷酒炖的炮制机理及其在都梁丸中应用的物质基础研究提供了科学依据。     

5173例儿童静脉滴注抗感染药物现状调查及护理对策

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。

目的:观察"分段切开,多重挂线术"治疗高位复杂性肛瘘的临床疗效。方法:将60例高位复杂性肛瘘随机分为治疗组40例,采用"分段切开,多重挂线术";对照组20例,采用传统切开挂线术进行对比观察。结果:显示治疗组与对照组显愈率分别为95%和90%,无明显差异(P>0.05),但两组间的术后疼痛程度、创口愈合时间、肛门功能情况存在显著差异(P<0.05)。结论:在治疗高位复杂性肛瘘时,"分段切开,多重挂线术"与传统切开挂线术相比,具有手术操作简单,对组织损伤小,痛苦小、疗程短、肛门功能保护好等优点,该术式的应用,使得高位复杂性肛瘘治疗更加安全、有效。     

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.
