血清血管紧张素转换酶的水平在阻塞性睡眠呼吸暂停低通气综合征患者中的变化研究

目的检测阻塞性睡眠呼吸暂停低通气综合征(OSAHS)患者中血清血管紧张素转换酶(ACE)水平的变化及其临床意义。方法设置OSAHS组(n=40)和健康对照组(n=40),测定并比较患者的血压、血脂和血清ACE水平在两组间的差异;分析ACE水平与患者病情变化、血压、血脂的相关性。结果 OSAHS患者在体重、BMI指数、颈围、腰围、AHI、收缩压、舒张压、TC、LDL-C和血清ACE方面高于健康人(P体重=0.002,P颈围=0.024,P腰围=0.038,PBMI=0.019,PAHI=0.001,P收缩压=0.001,P舒张压=0.001,PTC=0.017,PLDL-C=0.010,PACE=0.039),在LSa O2上低于健康人(PLSa O2=0.001)。OSAHS患者的收缩压、TC、ACE在轻中度和中重度之间均存在统计学差异(P收缩压=0.018、0.043,PTC=0.045、0.034,PACE=0.030、0.001),相关性分析显示,OSAHS患者中血清ACE与收缩压和TC均呈正相关(r=0.35,P=0.017;r=0.28,P=0.044)。结论 OSAHS患者血清ACE能反映患者病情的变化,并与血压和血脂具有一定相关性。     

Lenalidomide in the management of eosinophilic dermatosis of hematological malignancy

Eosinophilic dermatosis of hematological malignancy is a paraneoplastic skin eruption associated with chronic lymphocytic leukemia and other B‐cell malignancies. It clinically resembles an insect bite reaction and it can precede the symptoms of the hematological malignancy or be related to a more aggressive course. Different treatments have been proposed, but partial response and recurrence are frequent. Herein, we describe a case of eosinophilic dermatosis associated with mantle cell lymphoma with remission after lenalidomide therapy.     

玉液汤对2型糖尿病肥胖患者肠道菌群及脂质代谢的影响

目的：探讨玉液汤对2型糖尿病肥胖患者肠道菌群及脂质代谢影响。方法：选取2017年2月至2019年2月广州市中医医院收治的2型糖尿病肥胖患者106例作为研究对象，按照就诊顺序分为对照组和观察组，每组53例。2组均给予基础治疗+药物治疗，观察组再加用玉液汤治疗。观察2组治疗前、完成治疗后肠道菌群、脂质代谢、中医症状积分、血糖相关指标、体质量、腰围、体质量指数(BMI)变化并比较。结果：2组治疗前各指标比较差异无统计学意义（P>0.05），完成治疗后观察组患者的中医症状积分、FINS、HOMA-IR、HbAlc、BMI、腰围、体质量、TC、TG、LDL-C、肠杆菌、酵母菌、肠球菌、畏寒肢冷、腰膝酸软、脘腹2组患者治疗后HDL-C、双岐杆菌、乳杆菌、拟杆菌均较治疗后明显上升，且观察组高于对照组（P<0.05）。结论：玉液汤能改善2型糖尿病肥胖患者脂质代谢和临床症状，降低血糖，能调节肠道菌群紊乱，从而提高疗效。     

胎盘植入性疾病的危险因素及妊娠结局分析

目的探讨胎盘植入性疾病的危险因素及妊娠结局。 方法回顾性分析2009年1月至2017年12月广州医科大学附属第三医院/广州重症孕产妇救治中心围产资料数据库中信息完整的单胎妊娠孕妇48 650例临床资料，将这些孕妇分为胎盘植入性疾病组和非胎盘植入性疾病组，分析胎盘植入性疾病的危险因素及其妊娠结局。 结果单因素分析显示，年龄≥35岁、高中教育水平及以下、孕次≥3次、经产妇、人工流产史、剖宫产史、体外受精－胚胎移植受孕、合并前置胎盘是胎盘植入性疾病的相关危险因素(P<0.05)。多因素logistic回归分析显示，胎盘植入性疾病的独立危险因素为剖宫产史(OR＝2.254，95%CI：1.917～2.650)、体外受精－胚胎移植受孕(OR＝1.591，95%CI：1.212～2.089)、合并前置胎盘(OR＝28.282，95%CI：24.338～32.866)；与非胎盘植入性疾病产妇相比，患有胎盘植入性疾病产妇早产、剖宫产、产后出血、弥散性血管内凝血、产褥期感染、子宫切除、低出生体重儿、新生儿Apgar评分相对较低(1 min)、产妇入住重症监护病房的发生率明显升高(P<0.05)。 结论剖宫产史、辅助生殖受孕、合并前置胎盘是引起胎盘植入性疾病的独立危险因素，胎盘植入性疾病的妊娠结局不良。     

The preventive role of wheat germ oil against sertraline‐induced testicular damage in male albino rats

Sertraline is an antidepressant medication used extensively in the therapy of depression. The present investigation was intended to estimate the actual protective role of wheat germ oil on sertraline‐caused testicular injury in albino rats. Sertraline (human therapeutic dose, 15.63 mg/kg) was orally administrated to rats for 28 successive days. Sertraline‐administered rats were concurrently supplemented with wheat germ oil (human therapeutic dose, 68.75 mg/kg) for 28 successive days. Sertraline administration induced an elevation in testicular DNA damage and acute testicular damage illustrated by the histopathological alterations including marked degeneration and necrosis of germ cells lining seminiferous tubules, as well as interstitial oedema, congestion of interstitial blood vessel. Wheat germ oil administration potentially mitigated the histopathological alterations of sertraline‐administered rats. Lipid peroxidation, oxidative stress biomarker, showed a significant elevation in testicular tissue of sertraline‐administered rats. Furthermore, glutathione content and catalase activity were decreased in testicular tissue of sertraline‐administered rats. Serum testosterone level was elevated in sertraline‐administered rats. Wheat germ oil significantly reduced lipid peroxidation of testicular tissue and improved the antioxidant defences. Finally, wheat germ oil has a preventive role against testicular damage induced by sertraline in rats probably via its potential to prevent reactive oxygen species.
