The △^12 fatty acid desaturase was highly expressed in E. coli BL21（DE3）pLysS in the presence of isopropyl-D-thiogalactopyranoside （IPTG）. The fusion protein was purified and used to form a reaction system in vitro by adding oleic acid as substrate and incubating it at 20℃ for 6 h. Total fatty acids was extracted and methlesterified and then analyzed with gas chromatography. A novel peak corresponding to linoleic acid methyl ester standards was detected with the same retention time. GC-MS （gas chromatogram and gas chromatogram-mass spectrometry） analysis showed that the novel peak was linoleic acid methyl ester.

文摘目的综合评价激素补充治疗对更年期综合征患者生理、心理的生存质量的影响。方法观察性研究125例更年期综合征患者,按有无经过激素治疗分为2组:A组65例患者未经任何激素类药物治疗,B组60例经过了6个月的激素补充治疗;测量基本参数,并填写改良Kupperman评分、焦虑自评量表(self-rating anxiety scale,SAS)、抑郁自评量表(self-rating depression scale,SDS)、绝经期生存质量量表(menopause-specific quality of life questionnaire,MENQOL)。结果 60例实施激素补充治疗的更年期女性的Kupperman指数,SAS、SDS、MENQOL的结果均显著低于未经治疗者;35例患者治疗前后4项量表评分差异也有统计学意义。结论激素补充治疗不仅可以显著缓解患者围绝经期出现的躯体不适,还能够改善焦虑、抑郁程度,提高更年期综合征患者的生存质量。
文摘目的分析北京地区不同亚型多囊卵巢综合征(polycystic ovary syndrome,PCOS)病人临床特征及性激素、糖脂代谢特征。方法选择190例来自北京地区的女性,其中142例未经治疗的PCOS病人作为研究组,48例年龄匹配的健康女性作为对照组;根据2003鹿特丹PCOS诊断标准及美国国立卫生院(National Institute of Health,NIH)指南推荐将PCOS组病人分为4个亚型:亚型1,高雄激素+排卵异常(androgen excess+ovulatory dysfunction,AE+OD)40例;亚型2,高雄激素+卵巢多囊泡改变(androgen excess+polycystic ovarian morphology,AE+PCO)10例;亚型3,排卵异常+卵巢多囊泡改变(ovulatory dysfunction+polycystic ovarian morphology,OD+PCO)32例;亚型4,高雄激素+排卵异常+卵巢多囊泡改变(androgen excess+ovulatory dysfunction+polycystic ovarian morphology,AE+OD+PCO)60例。测量所有受试者的临床特征;测定血清性激素浓度及糖、脂代谢指标。结果 PCOS组病人的体质量指数(body mass index,BMI)、腰臀比(waist and hip ratio,WHR)、血清总睾酮(total testosterone,T)、黄体生成素(luteinizing hormone,LH)、LH/卵泡刺激素(follicle stimulating hormone,FSH)比值均高于对照组,差异有统计学意义(P<0.05);血清总胆固醇(total cholesterol,TC)、低密度脂蛋白胆固醇(low density lipoprotein-cholesterol,LDL-C)、三酰甘油(triglycerides,TG)及载脂蛋白B(apolipoprotein B,Apo B)浓度、Apo B/Apo A比值及空腹胰岛素(fasting insulin,INS)、胰岛素抵抗指数(homeostatic model assessment of insulin resistance,HOMA-IR)高于对照组,高密度脂蛋白胆固醇(high density lipoprotein-cholesterol,HDL-C)和载脂蛋白A(apolipoprotein A,Apo A)浓度低于对照组,差异有统计学意义(P<0.05)。亚型1的BMI、WHR、T及LDL均高于亚型3,TC及LDL较亚型2增高;亚型4的BMI、T及LDL高于亚型3,T、LH及LH/FSH较亚型2增高,差异有统计学意义(P<0.05);亚型2和亚型3之间各个临床特征及糖脂代谢参数的差异无统计学意义(P>0.05)。结论北京地区PCOS病人中向心性肥胖、脂代谢紊乱及胰岛素抵抗和高胰岛素血症的发病率较健康女性明显升高;同时具备排卵异常和高雄的亚型1和亚型4这2个亚型的脂代谢紊乱及胰岛素抵抗可能比较严重,而月经正常的亚型2和无高雄的亚型3其代谢变化相对比较温和,临床应加以区分并强调个体化治疗。
