妊娠和哺乳相关的骨质疏松症病例分享

妊娠和哺乳相关的骨质疏松症(pregnancy and lactation-associated osteoporosis, PLO)是一种罕见的临床特殊骨质疏松症,大多数病例出现在初产妇的妊娠晚期或产后早期,但是也会发生于经产妇中。PLO患者主要表现为在妊娠晚期以及产后初期严重的下背部疼痛、身高下降和脆性骨折,尤其是椎骨骨折。迄今为止,全球报道的PLO患者患病率仅有120余例。目前尚缺乏PLO治疗的指南与共识,各报告病例中指出双膦酸盐、钙和维生素D的补充是治疗PLO的一线疗法,此外特立帕肽、雷奈酸锶、地舒单抗也被证明有助于增加骨密度(bone density, BMD)。本文通过回顾分析两例PLO患者的临床资料,并对相关文献进行复习,以提高对PLO疾病的认识。     

DNA聚合酶θ对乳腺癌细胞株MCF-7放射敏感性的影响

目的 观察DNA聚合酶θ(POLQ)对人类乳腺癌细胞株MCF-7放射敏感性的影响.方法 实时荧光定量聚合酶链反应(qRT-PCR)和Western blot法检测siRNA转染前后POLQ表达率的变化;利用噻唑蓝(MTT)比色法、平板克隆形成实验、流式细胞术对不同实验组进行分析.结果 POLQ-siRNA组细胞POLQ mRNA和POLQ蛋白表达量分别是空白对照组的(12.16±0.56)％和(32.01±0.65)％ (P＜0.01).转染后72 h,POLQ-siRNA组、空白对照组细胞吸光度(A)值分别为(0.76±0.02)和(0.81 ±0.02),POLQ-siRNA 组细胞增殖能力明显低于空白对照组(P＜0.01);平板克隆形成实验分析结果显示POLQ-siRNA组放射增敏比(SER)为1.24(＞1),表明转染POLQ-siRNA后MCF-7细胞放射敏感性显著增强.结论 抑制POLQ表达可以显著提高MCF-7细胞对放射的敏感性.     

儿童少年卫生学与儿童保健学课程合并的优势

目的：探讨儿童少年卫生学与儿童保健学课程合并的理论基础以及课程合并后的优势所在。方法进行儿童少年卫生学与儿童保健学课程的讲授内容、教学大纲、教学进度表以及公共卫生执业医师考试大纲的对比分析。结果两门课程的教材内容出现大量的重复,并且相同知识点单独讲两门课的时候用的学时多。进行教学大纲的比较后分析出了相同知识点在合并课程还是处于重要的地位,而且符合公共卫生执业医师考试大纲内容。结论课程合并可以避免有关内容的重复,缩减相同内容重复讲解的课时,加强两门课程的内容联系,合并课程符合公共卫生执业医师资格考试大纲内容。     

仙台病毒RT-PCR检测方法的建立与应用

目的建立仙台病毒的RT—PCR方法并应用于常规检测。方法根据仙台病毒（gi：9627219）F蛋白的基因序列，设计Ff和Fr引物，以仙台病毒总RNA逆转录的cDNA为模板扩增出约609bp预期条带；将建立的RT—PCR方法应用于人工感染小鼠和送检细胞样品检测。结果八份感染小鼠样品中全部扩增出约609bp目的条带，16份肿瘤细胞样品有12份扩增出609bp目的条带。结论建立的仙台病毒RT—PCR方法是一种灵敏、快速、特异的方法，能够用于常规检测。     

神经原性膀胱NOS的免疫组化研究

目的研究一氧化氮合成酶(NOS)在神经原性膀胱(NB)的两种类型中的分布。方法应用免疫组化技术对23例患儿进行检测。将18例NB患儿按尿流动力学检查结果分为逼尿肌反射亢进型(11例)和逼尿肌反射低下型(7例),将非NB患儿5例按照有无尿道出口梗阻引起的膀胱静息压升高分为膀胱静息压升高组(2例)和正常组(3例)。结果NOS含量在逼尿肌反射亢进型较反射低下型有显著增高。膀胱内压升高组NOs含量较正常组明显升高。结论NOS参与膀胱功能的调节和神经原性膀胱的病生理变化。     

急性冠脉综合征合并糖尿病患者血浆TF、TFPI水平的研究

目的:探讨急性冠脉综合征(ACS)合并或不合并非胰岛素依赖性糖尿病(NIDDM)患者血浆组织因子(TF)?组织因子途径抑制物(TFPI)水平的特点?方法:选择ACS合并NIDDM患者22例?ACS不合并NIDDM患者21例?单纯NIDDM患者23例及正常对照组20例,应用ELISA法检测各组的TF?TFPI抗原水平,对比各组间指标,并对TF?TFPI水平进行相关性分析?结果:ACS合并或不合并NIDDM患者的TF和TFPI抗原水平皆显著高于对照组(P<0.01),且ACS合并NIDDM者高于不合并NIDDM者(P<0.05)及单纯NIDDM者(P<0.01);TF与TFPI抗原水平呈显著正相关(r=0.36, P<0.01)?结论:ACS患者存在凝血功能的异常状态,而ACS合并NIDDM患者的凝血功能异常更为明显,TF和TFPI水平升高可能是NIDDM患者发生ACS的预报因子?     

AQP-3在SD大鼠正常骨骼肌中的表达

目的观察水通道蛋白-3(AQP-3)在SD大鼠正常骨骼肌中的表达,为深入探讨AQP在大鼠骨骼肌肿胀状态下的表达及生理作用奠定基础。方法收集8只6月龄SD大鼠左后肢外侧股四头肌肌群中约200 mg肌肉组织,运用实时荧光定量PCR、Western blot检测AQP-3在大鼠肌肉组织中的表达。结果实时荧光定量PCR显示AQP-3 mRNA在肌肉组织中稳定表达;Western blot检测显示肌肉组织中AQP-3在36KD左右有一特异性条带。结论 AQP-3在SD大鼠正常肌肉组织中的稳定表达提示其可能参与肌肉组织内的液体平衡,对维持肌肉组织的正常生理功能、在创伤性肌肉肿胀的发病机制中可能有重要作用。

荷包包埋法在胃癌根治术十二指肠残端处理中的临床意义

Objective To explore the clinical effect of pockets embedding in duodenal stump closure after gastrectomy for gastric cancer. Methods A total of 2034 patients undergoing gastrectomy from January 1995 to December 2009 at our hospital were reviewed. Among them, Group A ( n = 465 ) underwent pockets embedding for duodenal stump, Group B (n =835) line-cutting stapler and hand-sewing while Group C (re = 734) double layer hand-sewing. The operation cost, processing time of duodenal stump,recent post-operative complications (within 1 month), blood loss volume and post-operative recovery status were compared between 3 groups. Results No patient died of operation. Ninety-five cases (4. 7% )suffered recent post-operative complications. The most frequent complications included wound infection (36 cases, 37.9%), intra-abdominal hemorrhage (18 cases, 18.9%) and anastomotic leakage (14 cases,14.7% ). There was no significant difference in intra-abdominal bleeding, anastomotic leakage, abdominal infection, wound infection or duodenal stump leakage among 3 groups. There was no duodenal stump leakage in Group A. The difference was apparent in comparisons with Groups B (6 cases, 0. 72% ) and C (5 cases,0.68%). The operation costs of Groups A [(9902 ±312)RMB] and C [(9896 ±281)RMB] were significantly lower than that of Group B [(13 129 ± 237) RMB, P =0. 0001]. And there was no difference between Groups A and C. The processing time of duodenal stump in Groups A [(7. 1 ±0. 9) min] and B [(7.6±0. 8)min] were lower than that of Group C [(11.5 ±1.4)min, P=0.0001]. And there was no difference between Groups A and B. There was no significant difference in blood loss volume or postoperative recovery status among 3 groups. Conclusion The post-gastrotomic closure of duodenal stump with pockets embedding for gastric cancer has a short operation time, a low operation cost and a low rate ofduodenal stump leakage. It is a simple, prompt, promising and safe surgical procedure for gastric neoplasms.
