电针对KOA大鼠关节软骨及软骨下骨降解相关蛋白表达的影响

目的：探讨电针对KOA大鼠关节软骨及软骨下骨降解相关蛋白表达的影响。方法：16只24月龄SD雄性大鼠随机分为老年组和电针组各8只,另8只6月龄SD雄性大鼠为青年组。电针组接受电针治疗（穴位：双侧“太溪”“足三里”“阳陵泉”“血海”;电针参数：疏密波,密波15Hz,疏波3Hz,电流1mA,每天1次,每次30min,每周5天,连续干预8周）,其余两组不做处理。干预8周后取材,ELISA法检测血清Ⅱ型胶原C端肽（CTX-Ⅱ）含量;显微CT检测左侧胫骨软骨下骨微结构;番红-固绿染色在光镜下观察左胫骨平台软骨组织形态结构,改良Mankin’s评分评估关节软骨退变程度;RT-qPCR、Western blot检测aggrecanase-2、SIRT1 mRNA及蛋白表达水平。结果：(1)与青年组大鼠相比,老年组CTX-Ⅱ含量增高（P<0.05）;番红-固绿染色显示老年组软骨表面结构破坏严重,出现裂层,软骨与软骨下骨分界不清,形态结构异常,染色不均;改良Mankin’s评分增加（P<0.05）;骨密度、骨体积分数、骨小梁数量减少（P<0.05）,骨小梁间距增大（P<0.05）...

妊娠期糖尿病与胰岛素抵抗

妊娠期胰岛素抵抗易导致妊娠期糖尿病,而遗传、胰岛素信号系统、胎盘因素、葡萄糖转运蛋白、浆细胞分化因子、肿瘤坏死因子α、瘦素等均参与胰岛素抵抗机制,与妊娠期糖尿病发病存在密切相关系.该文对上述因素参与胰岛素抵抗在妊娠期糖尿病发病机制中的作用作以综述.     

孕母叶酸摄入与MTHFR基因C677T多态性对子代先天性心脏病发病风险研究

目的 分析孕母孕早期环境高危因素,探讨叶酸摄入与MTHFR基因多态性间交互作用对子代先天性心脏病(简称先心病)发病的影响.方法 通过病例对照研究回顾性分析98例12岁以下先心病患者母亲和101例正常婴儿的母亲(对照组)孕期危险因素暴露水平以及叶酸摄入情况,进一步应用变性液相高效色谱(DHPLC)检测MTHFR基因C677T多态性,并分析其与叶酸摄入的交互作用.结果 经Logistic回归分析,6项因素纳入先心病风险模型,孕母教育程度、没有定期产检、精神紧张、接触化学物质是子代先心病的高危因素,服用叶酸和复合维生素是先心病的保护因素.叶酸补充充足情况下,MTHFR基因各基因型比较,病例组与对照组无统计学差异.将间断服用及未服用叶酸者合并作为叶酸补充不足者,其孕母基因型为CT与CC时发病无统计学意义(P=0.066,OR=2.018,95%CI:0.95～4.285).结论 提高孕母的自我保健意识是减少先心病危险因素暴露的重要措施.怀孕早期孕母叶酸的补充不足可能是导致子代先心病发病风险增高的独立因素,孕母MTHFR基因C677T基因型合并叶酸补充不足可能增加先心病风险.

Abstract：

Objective To explore the environmental risk factors,periconceptional folate intake and methylenetetrahydrofolate reduetase (MTHFR)gene C667T polymorphism of pregnant women on congenital heart diseases (CHD)in offspring.Methods Retrospective case-control study was carried out to investigate periconceptional folate supplementation and environmental factors in 98 parents with CHD offsprings and 101 parents with normal offsprings.The mothers'MTHFR gene C667T mutation was also identified.The possible risk factors were analyzed by simple and multiple factors Logistic regression methods.Results Six factors were related to the occurrence of CHD in the offspring:education of gestation mother,no prenatal examination,under depressed or nervous condition during pregnancy and maternal exposures to harmful substance;periconceptional folate and compound vitamin supplementation were protection factors.There were significant difference between case and control group in folate supplement(P<0.05).The maternal MTHFR 677genotypes CC and TT in combination with daily folate supplements were associated with no increased risk for CHD in offspring,however in combination with not use of folate a two-fold(P=0.066,OR=2.018,95%CI 0.95-4.285)increased risk.Conclusion Improving self health care of gestational mother is the most important protection measures to avoid the risk factors exposure.Periconceptional folate deficiency may be the independence risk factor for CHD.Periconceptional mother carrying MTHER heterozygote's(CT)genotype in combination with deficiency may increase risk for CHD.     

Transcutaneous electrical nerve stimulation on acupoints relieves labor pain: A non-randomized controlled study

Objective：To investigate the efficacy of transcutaneous electrical nerve stimulation（TENS）on four specific acupuncture points Hegu（LI4）,Neiguan（PC6）,Danshu（BL19）and Weishu（BL21）for reducing pain in labor.Methods：A total of 160 voluntary nulliparous women who were willing to receive TENS for analgesia were assigned to the treatment group after cervical dilation of more than 2 cm.Another 145 matched nullipara were recruited as the control group.Visual analogue scale（VAS）was used to assess the pain before and 0.5 h after the application of TENS.Then,VAS was assessed every one hour until delivery.Percentage of VAS score decreased by〉25%was the primary outcome,the delivery mode and neonatal outcome were measured as secondary outcomes.Adverse reactions were also recorded during TENS.Results：The percentage of VAS score decreased by〉25%was 68.6%in the TENS treatment group.Maternal delivery mode and neonatal outcomes were not significantly different between the two groups.In addition,the incidence of postpartum hemorrhage in the TENS treatment group was less than the control group（P〈0.05）.There was no adverse reaction recorded with TENS on acupoints.Conclusion：As a novel and non-invasive approach,TENS on specific acupoints including Hegu（LI4）,Neiguan（PC6）,Danshu（BL19）and Weishu（BL21）was an effective method for analgesia in labor.     

高龄股骨颈骨折患者术后肺部感染的预防护理

正高龄股骨颈骨折多因生活中的轻度碰撞、不可避免的外力所致[1],患者术后机体抵抗力降低、愈合慢,呼吸道防御功能下降,细菌易感性增加,使肺部感染损害更明显[2]。本研究通过对87例股骨颈骨折患者的护理干预,有效降低了肺部感染发生率,现报道如下。一、资料与方法1.一般资料:选取我院2014年至2015年收治的87例
