消炎痛治疗宫内放环后出血

积极治疗节育手术并发症是搞好计划生育的一个重要环节。月经异常是宫内放置节育环的主要并发症，也是节育环停止使用的主要原因。近几年来本人采用消炎痛治疗官内放环后月经异常，取得了良好的效果。     

氯氮平、氟哌啶醇和氯丙嗪对慢性精神分裂症患者糖、脂代谢及体质量的影响

目的 探讨氯氮平、氟哌啶醇和氯丙嗪对慢性精神分裂症患者的糖、脂代谢和体质量的影响。方法 对服用氯氮平（89例，氯氮平组），服用氟哌啶醇（87例，氟哌啶醇组）及服用氯丙嗪（83例，氯丙嗪组）治疗的慢性精神分裂症患者于治疗前后的不同时间进行血糖、胰岛素、血脂及体质量测定，并做相关因素分析。结果 氯氮平组治疗第90天和第180天空腹血糖异常（空腹血浆血糖〉7.0mmo/L）的发生率分别为8％及24％，氟哌啶醇组分别为1％和2％，氯丙嗪组分别为1％及4％。治疗第90天氯氮平组和氯丙嗪组的空腹及餐后2h血糖浓度均较治疗前升高，治疗第180天的血糖浓度高于第90天，氟哌啶醇组各时点的变化则不明显；差异均有统计学意义（P均〈0．01）。治疗第90天，氯氮平组的体质量平均高于治疗前5．5％，氯丙嗪组高于治疗前4．8％；治疗第180天两组分别高于治疗前9．1％和7．4％；氟哌啶醇组则无明显变化；三组间的差异有统计学意义（P〈0．01）。三组患者治疗第180天的胰岛素浓度均高于治疗前，差异均有统计学意义（P均〈0．01），但三组间的差异无统计学意义（P〉0．05）。氯氮平组和氯丙嗪组的胆固醇和甘油三酯浓度均高于治疗前，差异均有统计学意义（P均〈0．01），氟哌啶醇组则无明显变化。治疗第180天氯氮平组和氯丙嗪组患者血糖、胰岛素、血脂浓度与体质量均有一定相关性（r=0．23-0．39）；氯氮平组的血糖、体质量、血脂代谢还与血药浓度呈显著性相关（r=0．28-0．62），差异均有统计学意义（P〈0．05或〈0．01）。结论 氯氮平和氯丙嗪治疗影响慢性精神分裂症患者的糖、脂代谢及体质量。     

早产患者血清粒细胞集落刺激因子的检测及其意义

目的探讨粒细胞集落刺激因子(G-CSF)与自发性早产的关系及其对预测早产的可能意义。方法采用ELISA-双抗体夹心法分别对28-34周、34-37周不同孕龄组早产妇女及正常妊娠妇女的血清G-CSF进行检测。结果孕28-34周早产妇女血清G-CSF水平较正常对照组妇女升高(P<0.05)。结论高水平的血清G-CSF与妊娠<34周发生的早产有关,检测妊娠妇女血清G-CSF水平对预测妊娠34周之前发生的早产有重要意义。     

氯氮平和利培酮对精神分裂症患者体质量的影响

目的:探讨氯氮平和利培酮对精神分裂症患者体质量(体重)的影响及相关因素。方法:选择符合国际疾病分类第10版(ICD-10)精神分裂症的诊断标准,空腹血糖正常,无严重躯体疾病,1周内未用任何抗精神病药的住院患者,共计65例,其中利培酮组32例,氯氮平组33例。两组患者于治疗前和治疗6周末分别做葡萄糖耐量试验,测空腹血胰岛素,测量体质量、身高,计算体质量指数(BMI),评定阳性与阴性症状量表(PANSS)。结果:①治疗后体质量增加者氯氮平组24例(占72.7%),利培酮组19例(占59.4%);氯氮平组体质量平均增加2.5kg,利培酮组1.4kg;②氯氮平组体质量增加与进食量增加、胰岛素水平增加和PANSS评分减分率相关(P<0·05),体质量增加者餐后1h血糖升高;③利培酮组体质量增加与年龄、病程显著相关(P<0·05),与基础BMI存在负相关倾向;④两组治疗后均出现糖耐量减低(IGT)和暂时诊断糖尿病(DM)。结论:氯氮平和利培酮均能导致体质量增加,体质量增加更易对糖代谢造成不良影响。     

Steroid pulse therapy impaired endothelial function while increasing plasma high molecule adiponectin concentration in patients with IgA nephropathy.

BACKGROUND: Decreased plasma adiponectin is associated with impaired endothelial function and, thereby, increased risk for cardiovascular events. Glucocorticoid (GC) affects vascular endothelial cells either favourably or harmfully depending upon the dosages and duration. We examined the effect of GC pulse therapy on vascular endothelial function. METHODS: Fourteen young patients with IgA nephropathy were evaluated for flow-mediated vasodilation (FMD), plasma levels of adiponectin both in high molecular weight (HMW adiponectin) form and in single molecular form (total adiponectin), hepatocyte growth factor (HGF), asymmetric dimethylarginine (ADMA), and high-sensitive C-reactive protein, before and after a course of GC pulse therapy. RESULTS: GC pulse therapy significantly decreased FMD (from 7.2 +/- 2.6 to 5.7 +/- 2.5%, P < 0.01). Meanwhile, plasma adiponectin levels were significantly augmented (total adiponectin: from 10.2 +/- 4.0 to 12.1 +/- 6.3 microg/ml, P < 0.05; HMW: from 6.5 +/- 3.2 to 7.7 +/- 3.3 microg/ml, P < 0.05). In parallel, elevated concentrations of serum HGF (from 0.28 +/- 0.12 to 0.63 +/- 0.38 ng/ml, P < 0.01) and plasma ADMA (from 0.45 +/- 0.07 to 0.53 +/- 0.04 nmol/ml, P < 0.05) were observed. CONCLUSIONS: GC pulse therapy impaired endothelial function while increasing plasma adiponectin levels, which may in turn restore the endothelial function in patients with IgA nephropathy.     

胎儿生长迟缓与新生儿胰岛素敏感性变化的相关性

目的探讨胎儿生长迟缓(FGR)与新生儿胰岛素敏感性变化的关系。 方法昆明医学院第一附属医院于2004年4~12月，对72例小于胎龄儿(SGA)和48例适于胎龄儿(AGA)空腹血糖(FPG)、空腹胰岛素(FINS)、C 肽、HDL C、LDL C、TG、非酯化脂肪酸(NEFA)等指标，计算葡萄糖/胰岛素比值(G/I)、胰岛素敏感性指数(ISI)、胰岛素抵抗指数(HOMA IR)、胰岛β细胞功能(HBCI)等，探讨FGR与新生儿胰岛素敏感性变化的关系。 结果(1)SGA组FPG、HDL C低于AGA组，而FINS、LDL C、TG、NEFA高于AGA组(P<001)；(2)SGA组G/I比值、ISI低于AGA组，HOMA IR高于AGA组(P<001)，而HBCI两组相比差异无显著性(P>005)。 结论FGR儿在生命早期存在胰岛素敏感性降低和不同程度的胰岛素抵抗(IR)，而胰岛β细胞功能无明显变化。     

Effect of maternal and infant covariates on sibship correlation in birth weight

Birth weight on 12,644 singleton infants from 6,196 sibships born in Maryland between 1980 and 1984 were used to estimate the effects of nine maternal and infant covariates on the sibship correlation in birth weight. Assuming a homogeneous correlation across all families, the estimated intraclass correlation was 0.4664 (+/- 0.0099). This high sibship correlation makes it possible to predict, with reasonable accuracy, the birth weight of a child given information on previous sibs, as well as covariates on the mother and/or infant pertinent to a given pregnancy. The reduction in variance associated with incorporating information on the nine covariates used here was approximately equal to that obtained by conditioning on a single previous sib. Testing for heterogeneity in correlation among different groups of families showed that a crude measure of parity (first live birth vs. other), time between births, mother's marital status, and maternal age at the birth of the last child significantly influenced the sibship correlation in birth weight.     

Stoma Adjustable Silicone Gastric Banding versus Vertical Banded Gastroplasty for the Treatment of Morbid Obesity

Background: Among gastric restrictive operations, the procedure of choice is still controversial. The aim of this study is to compare the results of two different gastric restrictive procedures: vertical banded gastroplasty (VBG) and stoma adjustable silicone gastric banding (ASGB). Methods: Between 1991 and 1996, 51 patients were treated surgically for morbid obesity: 27 underwent VBG and 24 underwent ASGB. Preoperative body weight (BW), body mass index (BMI) and percentage of ideal body weight (% IBW) were (mean ± SD): 145.7 ± 45.3 kg; 53.9 ± 15.9 kg/m²; 249.1 ± 73.5% respectively in the VBG group. Corresponding figures for the ASBG group were 132.5 ± 22.7 kg; 46.9 ± 7.8 kg/m² and 207.2 ± 35.0%. Results: In the VBG group, the median follow-up period was 26 months (range: 7-47). Eighteen months after the operation BW, BMI, % IBW and percentage of excess weight loss (% EWL) were 85.5 ± 26.8 kg, 31.9 ± 9.8 kg/m², 145.4 ± 43.9% and 74 ± 1% respectively. Complications included incisional hernia (n = 1), and bowel obstruction (n = 1). One patient died of acute myocardial infarction on the third postoperative day. In the ASGB group, median follow-up time was 19.7 months (range: 18-26). At 18 months postoperation BW, BMI, % IBW and % EWL values were 86.6 ± 20.6 kg 30.6 ± 6.6 kg/m2 140.6 ± 29.3% and 64 ± 1% respectively. Gastric wall erosion occurred in two patients and the bands had to be removed. These patients underwent VBG 6 months later. Complications encountered in this group were incisional hernia (n = 1), outlet stenosis and reflux esophagitis (n = 1), reservoir leakage (n = 1) and gastrointestinal bleeding (n = 1). Two patients died of pulmonary embolism and acute gastrointestinal bleeding. Conclusions: Weight reduction was not statistically significant between the two groups. ASGB was easier to perform and less invasive than VBG.     

New stand magnifiers do not meet rated levels of performance

A new range of stand magnifiers has been released by the COIL company in the United Kingdom. Examination of these magnifiers reveals that they fail to deliver the rated magnifications labelled prominently on the appliances, as a result of the manufacturer's conformance with the requirements of the German DIN standard and the use of back vertex power (F'_v) rather than equivalent dioptric power (F_m) of the magnifier. In this study we provide information on the optometric parameters of these new stand magnifiers that will assist the more accurate specification of improvements in vision expected from their use.     

The HGAR1 familial hypercholesterolemia pedigree

Data on 232 members of a single pedigree, descended from two pairs of original parents, were made available to the participants of Genetic Analysis Workshop 8 (GAW8). In addition to information concerning age and sex, measurements for 10 quantitative traits and genotypes at 22 polymorphic marker loci were also provided for a subset of 193 of these family members. © 1993 Wiley-Liss, Inc.
