目的:观察中药益气活血通络汤治疗高血压合并糖耐量减低的临床疗效。方法:将64例高血压合并糖尿病患者,随机分为2组各32例,对照组口服硝苯地平片治疗;观察组加用中药益气活血通络汤,以治疗前后收缩压(SBP)、舒张压(DBP)、三酰甘油(TG)、总胆固醇(TC)、高密度脂蛋白胆固醇(HDL-C)、低密度脂蛋白胆固醇(LDL-C)、血糖、胰岛素、胰岛素敏感性指数(ISI)、胰岛素抵抗指数(HOMA-IR)为观察指标。结果:治疗3个月后,观察组疗效优于对照组(Z=-1.998,P<0.05)。与治疗前比较,2组经治疗后SBP、DBP、TC、TG、LDL-C均下降,HDL-C上升,差异有统计学意义(P<0.05);观察组治疗后SBP、DBP、TC、TG、LDL-C、HDL-C与对照组治疗后比较,差异有统计学意义(P<0.05)。与治疗前比较,2组经治疗后空腹和餐后2 h血糖、胰岛素、HOMA-IR均下降,ISI上升,差异有统计学意义(P<0.05);且经治疗后,观察组上述所有指标改善情况均优于对照组,差异有统计学意义(P<0.05)。2组患者在3个月的治疗期间中均未出现严重不良反应。结论:中药益气活血通络汤治疗高血压合并糖耐量降低疗效较好且安全性高,能显著降低血压,改善血脂。     

人格特质对二胎返岗护士产适应水平的影响

目的 了解二胎返岗护士适应水平现状,并探讨人格特质对其返岗适应水平的影响。方法 2018年1-12月,采用便利抽样法选取山东省3所三级甲等医院360名护士为研究对象,采用一般资料调查表、艾森克人格问卷、护士产后返岗适应问卷对其进行调查。结果 护士产二胎后返岗适应水平均分为(2.16±0.51)分;外向型人格特征与返岗适应水平呈正相关(r=0.540,P<0.001),精神质、神经质人格特征与返岗适应水平均呈负相关(r=-0.410,P<0.001;r=-0.350,P<0.001)。多元线性回归分析结果显示,年龄、返岗时间、工作负荷、返岗培训、内-外倾向、精神质、神经质是护士产二胎后返岗适应的独立影响因素。结论 护士产二胎后返岗适应处于中等偏下水平,人格特质、生育年龄、返岗时间、工作负荷、返岗培训为其影响因素,护理管理者可结合人格特质等特点采取管理策略,提高护士产二胎后返岗适应的水平。     

In Vivo Kinematics of Functional Ankle Instability Patients and Lateral Ankle Sprain Copers During Stair Descent

Patients with mechanic ankle instability experience increased tibiotalar and subtalar joint laxity. However, in vivo joint kinematics in functional ankle instability (FAI) patients and lateral ankle sprain (LAS) copers, especially during dynamic activities, are poorly understood. Ten FAI patients, 10 LAS copers, and 10 healthy controls were included in this study. A dual fluoroscopic imaging system was used to analyze the tibiotalar and subtalar joint kinematics during stair descent. Five key poses of stair descent were analyzed. Kinematic data from six degrees of freedom were calculated utilizing a solid modeling software. The range of motion and joint positions in each degree of freedom were compared among the three groups. The tibiotalar joints of FAI patients and LAS copers were significantly more inverted than those of healthy controls during the foot strike (p = 0.016, = 0.264). The subtalar joints of FAI patients were significantly more anteriorly translated (pose 2, p = 0.003, = 0.352; pose 3, p < 0.001, = 0.454; pose 4, p = 0.004, = 0.334), inverted (pose 4, p = 0.027, = 0.234; pose 5,p = 0.034, = 0.221), and externally rotated (pose 4, p = 0.037, = 0.217; pose 5; p = 0.004, = 0.331) than those of healthy controls during the mid‐stance and the heel off. The FAI patients showed excessive tibiotalar inversion and subtalar joint hypermobility during stair descent. Meanwhile, the LAS copers maintained subtalar joint stability, and only showed excessive tibiotalar inversion in foot strike. These data provide insight into the mechanisms behind the development of FAI after initial LAS. © 2019 Orthopaedic Research Society. Published by Wiley Periodicals, Inc.

保妇康凝胶联合诺氟沙星治疗宫颈糜烂50例疗效观察

目的：探讨保妇康凝胶联合诺氟沙星治疗宫颈糜烂的临床效果。方法将100例宫颈糜烂患者根据随机数字表法分为观察组和对照组各50例。观察组给予保妇康凝胶和诺氟沙星联合治疗，对照组单独给予治糜灵栓治疗，比较两组患者临床症状的变化，并对临床疗效进行评价。结果观察组治愈率为86.00%，明显高于对照组的74.00%，临床症状评分改善较对照组明显，且其临床症状消失的时间短于对照组，差异均有统计学意义(P<0.05)。结论保妇康凝胶与诺氟沙星合用比治糜灵栓治疗宫颈糜烂效果更佳，且治愈时间上明显较优，值得临床上推广应用。

目的 比较生物型与骨水泥型假体全髋关节置换术(THA)治疗老年移位型股骨颈骨折(DFNF)的临床疗效.方法 前瞻性纳入2015年7月—2018年6月佳木斯大学附属第一医院骨科收治的老年DFNF患者128例,男性71例,女性57例;年龄61～84岁,平均72.7岁.骨折原因:跌伤75例,撞伤32例,高处坠落伤21例.依据随机数字表法分为生物型假体THA组(BPTHA组,n=64)与骨水泥型假体THA组(CPTHA组,n=64).BPTHA组行生物型假体髋关节置换,CPTHA组行骨水泥型假体髋关节置换.观察两组术中出血量、手术时间、术后引流量等围术期指标及住院时间.比较术前及术后6、12个月髋关节功能(Harris),血清前列腺素缓激肽(BK)、5-羟色胺(5-HT)等疼痛因子水平及视觉模拟评分(VAS),血清淀粉样蛋白A(SAA)、C反应蛋白(CRP)、红细胞沉降率(ESR)等炎性反应指标水平;分析术后并发症发生情况.结果 两组术中出血量、手术时间、术后引流量差异均无统计学意义(P>0.05);BPTHA组住院时间长于CPTHA组[(19.76±2.24)d vs.(15.37±1.71)d,P<0.05].术后6个月,BPTHA组Harris评分低于CPTHA组[(81.72±8.37)分vs.(86.68±8.85)分,P<0.05];术后12个月,BPTHA组Harris评分高于CPTHA组[(95.54±9.67)分vs.(90.72±9.12)分,P<0.05].术后6个月,BPTHA组血清BK、5-HT、SAA、CRP、ESR水平及VAS均高于CPTHA组(P<0.05);术后12个月,BPTHA组血清BK、5-HT、SAA、CRP、ESR水平及VAS均低于CPTHA组(P<0.05).BPTHA组并发症发生率为3.13％,CPTHA组并发症发生率为4.69％,两组比较差异无统计学意义(P>0.05).结论 BPTHA、CPTHA均可应用于老年DFNF的临床治疗,但CPTHA近期疗效优于BPTHA,而BPTHA远期疗效优于CPTHA.     

Effects of probiotics on gastrointestinal complications and nutritional status of postoperative patients with esophageal cancer: A protocol of randomized controlled trial

Background:Gastrointestinal complications and malnutrition are common problems that affect postoperative rehabilitation and survival of patients with esophageal cancer. Evidence has shown that probiotics have a positive effect on improving gastrointestinal complications and nutritional status of patients with esophageal cancer after surgery, but there is a lack of prospective studies on this topic. We designed this prospective randomized controlled trial to evaluate the effects of probiotics on gastrointestinal complications and nutritional status in patients with postoperative esophageal cancer.Methods:This is a prospective, randomized, double-blind, placebo-controlled trial. It was approved by the Clinical Research Ethics Committee of our hospital. 192 patients will be randomly divided into probiotics group and the placebo group in a 1:1 ratio. After operation, probiotics and placebo will be given orally for 8 weeks. The indexes of nutritional status and incidence of digestive tract complications will be recorded and the data will be analyzed by SPSS 18.0 software.Discussion:This study will evaluate the effect of probiotics on gastrointestinal complications and nutritional status of postoperative patients with esophageal cancer. The results of this study will provide clinical basis for the use of probiotics in postoperative treatment of esophageal cancer.Trial registration:OSF Registration number: D DOI 10.17605/OSF.IO/QHW86
