脂肪肝患者血清瘦素测定的临床意义

目的：检测脂肪肝患者血清瘦素（LEP）水平，探讨瘦素与暗肪肝患者的血脂、血尿酸及血清铁蛋白（FePr）之间的关系。方法：2002年6月至2004年8月我院62例脂肪肝患者及30例正常对照组患者血清瘦素水平，同时测定血脂、血尿酸和血清铁蛋白。结果：（1）脂肪肝患者LEP水平、血尿酸、血清铁蛋白均高于对照组（P＜0．01，P＜0．05）。（2）LEP与血尿酸及血清铁蛋白呈正相关。结论：脂肪肝患者存在高瘦素水平并与血尿酸及血清铁蛋白呈正相关，瘦素水平可以作为脂肪变性严重程度的独立预测指标。     

游泳运动对大鼠脂肪肝预防作用的研究

本文采用实验研究方法,通过建立大鼠脂肪肝模型,研究了有氧运动对脂肪肝的预防作用效果,探讨其可能机理。实验中选取2个月龄雄性SD大鼠30只,随机分为对照组、单纯高脂饮食组、高脂饮食+运动组等三组。5周后对各组大鼠进行SOD、MDA指标的检测,并做病理组织学观察。实验结果表明,高脂饮食组大鼠肝脏MDA升高、SOD活性较对照组活性降低。HE组MDA值低于H组,SOD值明显高于H组。病理学检查肝脏脂肪变性不明显。     

脑梗死患者血脂水平检测及临床意义

目的探讨血脂水平与脑梗死的关系。方法通过对137例急性脑梗死患者与对照组血脂变化观察,多因素分析用SPSS10.0软件包中的Logistic回归方程,计算相对危险度(RR),RR的95%可信限(CI)。结果脑梗死组TC、TG、LDL-C浓度均明显高于对照组,而HDL-C浓度明显低于对照组。结论血清TC>6.0mmol/L才增加脑梗死的风险,而HDL-C浓度≥0.85mmol/L可降低脑梗死的风险。     

北京地区儿童性别年龄别身体组成成分检测的意义

目的应用电阻抗法了解北京地区正常儿童性别年龄别身体组成成分。方法选择北京市西城区中、小学6~14岁、相对体质量在正常范围(80%~120%)内的健康儿童587名,排除慢性疾病。用电阻抗法测量和计算体脂肪(BF)率、体脂肪量、除脂肪量。结果除脂肪量和脂肪量在男、女童两组均随着年龄的增加而增加。男童组各年龄段除脂肪量高于女童组,体脂肪率低于女童组。当体质量指数(BMI)<20 kg/m2时,男、女童BF率显示一个高值状态。结论我国儿童体BF率比BMI预计的要高。

胃癌患者血清瘦素及体脂的变化

目的探讨胃癌患者血清瘦素及体脂的变化.方法检测49例胃癌患者和53例正常对照的血清瘦素和体脂,并检测胃癌患者手术后一天和七天的血清瘦素.结果胃癌组和正常对照组的血清瘦素与体脂均呈正相关,胃癌患者瘦素和体脂水平均较正常低.术后血清瘦素短暂增高,一周时间恢复至术前水平.结论胃癌患者瘦素水平降低,并与体脂相关,手术对胃癌患者瘦素有短暂影响.     

"循经移疮泄毒"治疗癌肿方法的初步构建及临床意义

目的:构建"循经移疮泄毒"治疗晚期癌肿方法的操作流程,并初步分析其临床意义。方法:对晚期肝癌患者循足厥阴肝经在"膝关"腧穴下行部位实施移疮泄毒,采用ELECSYS电化学分光免疫法对移疮部位的渗出液和同期血清中肿瘤标志物癌胚抗原(CEA)等进行检测,并与非肝经所对应脏腑晚期癌肿患者的循肝经移疮泄毒疗效进行对比分析。结果:在晚期肝癌患者循肝经移疮泄毒的发疱液中检出高于血清浓度的癌胚抗原(CEA)等物质。结论:采用"循经移疮泄毒"法,有助于癌肿毒性物质排出体外。     

Antidiabetic and Anti-oxidative Effects of Honokiol on Diabetic Rats Induced by High-fat Diet and Streptozotocin

Objective To study the antidiabetic and anti-oxidative effects of honokiol(Hon)in Magnolia officinalis and its underlying molecular mechanism in diabetic rats induced by high-fat diet(HFD)and streptozotocin(STZ).Methods After ig administration with Hon[25,50,and 100 mg/(kg·d)]to diabetic rats for consecutive 10 weeks,the levels of blood glucose(BG),oral glucose tolerance(OGT),blood lipids including total cholesterol(TC),triglyceride(TG),high density lipoprotein-cholesterol(HDL-C),and low density lipoprotein-cholesterol(LDL-C),hepatic oxidative stress including the activities of superoxide dismutase(SOD),catalase(CAT),glutathione peroxidase(GSH-Px),methane dicarboxylic aldehyde(MDA),and cytochrome P4502E1(CYP2E1)in diabetic rats were measured.Results Compared to the diabetic control rats,ig administration of Hon resulted in significant decrease in BG,TC,TG,and LDL-C levels in serum,as well as hepatic CYP2E1 activity and MDA content in diabetic rats,whereas the level of OGT and activities of hepatic CAT,SOD,and GSH-Px in diabetic rats were significantly increased.Conclusion Hon could alleviate hyperglycemia,hyperlipemia,hepatic oxidative damage,and insulin resistance in diabetic rats by inhibiting hepatic CYP2E1 activity.     

炎症上调SREBP-1致C57BL/6J小鼠肝脏脂质积聚

目的：研究炎症是否通过影响核转录因子固醇调节元件结合蛋白1(SREBP1)而致C57BL/6J小鼠肝脏脂质的异常聚集。方法：将8周龄C57BL/6J雄性小鼠随机分为对照组(n=6)和炎症组(n=6)组,两组均喂以高脂饮食,炎症组小鼠皮下注射酪蛋白建立慢性炎症模型,对照组注射相应量磷酸盐缓冲液,18周后处死,测定血清中炎症介质水平及肝脏中的脂质水平,油红O染色观察肝脏脂质沉积情况,实时定量PCR和Western blotting检测肝脏炎症因子TNF-α、MCP1及脂肪酸合成相关基因SREBP1、ACCα、FAS的基因和蛋白水平。结果：与对照组相比,炎症组血清中的炎症因子IL-6和SAA水平以及肝脏中炎症因子MCP1 和 TNF-α的mRNA和蛋白水平均显著上升(P<0.05)。炎症状态下,肝脏甘油三酯和游离脂肪酸含量显著高于对照组(分别为0.21?0.07 vs 0.40?0.14mg/mg,P<0.05;3.80?0.58 vs 5.38?1.38nmol/mg,P<0.05)。油红O结果显示,炎症使脂质积聚更显著。SREBP1及其下游与脂肪酸和甘油三酯合成相关的基因ACCα,FAS的mRNA和蛋白水平在炎症组均显著上升(P<0.05)。结论：炎症可能通过上调SREBP1,加重脂质在肝脏的聚集。     

Does Timing Matter? A Narrative Review of Intermittent Fasting Variants and Their Effects on Bodyweight and Body Composition

The practice of fasting recently has been purported to have clinical benefits, particularly as an intervention against obesity and its related pathologies. Although a number of different temporal dietary restriction strategies have been employed in practice, they are generally classified under the umbrella term “intermittent fasting” (IF). IF can be stratified into two main categories: (1) intra-weekly fasting (alternate-day fasting/ADF, twice-weekly fasting/TWF) and (2) intra-daily fasting (early time-restricted eating/eTRE and delayed time-restricted eating/dTRE). A growing body of evidence indicates that IF is a viable alternative to daily caloric restriction (DCR), showing effectiveness as a weight loss intervention. This paper narratively reviews the literature on the effects of various commonly used IF strategies on body weight and body composition when compared to traditional DCR approaches, and draws conclusions for their practical application. A specific focus is provided as to the use of IF in combination with regimented exercise programs and the associated effects on fat mass and lean mass.
