新疆护理专职教师工作压力现状及影响因素

目的探讨新疆护理教师工作压力现状并分析其影响因素,为提出护理教师队伍建设的相关对策提供实证依据并为护理院校管理和教师人才队伍的可持续发展提出建议。方法采用高职教师工作压力量表对新疆15个地、市、州抽取的10所护理院校在编在岗的256位护理教师进行问卷调查,调查其工作压力现状并分析其影响因素。结果护理专职教师的工作压力得分为（2．436±0．576）分,大于2分,说明教师的工作压力大。教龄、婚姻、兼职情况及教学工作量不同的教师因社会因素而产生的工作压力水平不同,不同婚姻状况的教师因学校管理及制度因素产生的压力水平不同,性别、年龄、学历、婚姻、教学工作量不同的教师个人职业发展所带来的压力水平不同,性别、教龄、每周课时量等在护理院校教师工作压力不同;年龄、婚姻状况、教学工作量不同的教师因人际关系产生的工作压力水平不同,性别、年龄、教龄、职称、婚姻、教学工作量、收入水平及兼职情况不同的教师因工作负荷压力水平不同,性别、职称、婚姻、教学工作量、担任教学课程不同的教师因个人特质因素带来的工作压力不同,差异均有统计学意义（P〈0．05）。结论护理专职教师的工作压力大,来源是多方面的,学校管理制度和社会因素带来的压力最大,因此应尽快改变社会各界对护理教育认识上的不足和偏见,明确护理教育的定位,加大国家对护理教育的投入,同时护理教师应提高对自己职业的认识,合理制定自己的职业生涯发展规划。     

Fatty acid-binding protein-4 as a biomarker predicting acromegaly-associated diabetes mellitus

Background/aimThe known pathogenesis of diabetes mellitus (DM) in acromegaly is mainly based on growth hormone (GH) and insulin-like growth factor-1 (IGF-1) excess. Fatty acid-binding protein 4 (FABP-4), a novel adipokine, is found to induce insulin resistance and type 2 DM. We aimed to investigate the possible effect of FABP-4 on glucose metabolism in patients with acromegaly.Materials and methodsThis case-control study included 28 patients newly diagnosed with acromegaly and 57 healthy volunteers. The patients with acromegaly were classified according to their glycemic status as with DM, prediabetes, and normal glucose tolerance. Anthropometric measurements, laboratory test results, and FABP-4 levels of the subjects were evaluated.ResultsAlthough no difference was observed in FABP-4 levels between acromegaly and control groups, the FABP-4 level was higher in the patients with acromegaly having DM compared to the patients with acromegaly having prediabetes and NGT, and the control group (p = 0.004, p = 0.001, p = 0.004, respectively). Logistic regression analysis suggested that the FABP-4 is an independent predictor of DM in acromegaly (β = 7.382, OR = 38.96, 95% CI: 1.52-5.76, p = 0.018).Conclusion The FABP-4 may be a helpful predictor of acromegaly-associated DM.     

A systematic review of the evidence for Canada's Physical Activity Guidelines for Adults

This systematic review examines critically the scientific basis for Canada's Physical Activity Guide for Healthy Active Living for adults. Particular reference is given to the dose-response relationship between physical activity and premature all-cause mortality and seven chronic diseases (cardiovascular disease, stroke, hypertension, colon cancer, breast cancer, type 2 diabetes (diabetes mellitus) and osteoporosis). The strength of the relationship between physical activity and specific health outcomes is evaluated critically. Literature was obtained through searching electronic databases (e.g., MEDLINE, EMBASE), cross-referencing, and through the authors' knowledge of the area. For inclusion in our systematic review articles must have at least 3 levels of physical activity and the concomitant risk for each chronic disease. The quality of included studies was appraised using a modified Downs and Black tool. Through this search we identified a total of 254 articles that met the eligibility criteria related to premature all-cause mortality (N = 70), cardiovascular disease (N = 49), stroke (N = 25), hypertension (N = 12), colon cancer (N = 33), breast cancer (N = 43), type 2 diabetes (N = 20), and osteoporosis (N = 2). Overall, the current literature supports clearly the dose-response relationship between physical activity and the seven chronic conditions identified. Moreover, higher levels of physical activity reduce the risk for premature all-cause mortality. The current Canadian guidelines appear to be appropriate to reduce the risk for the seven chronic conditions identified above and all-cause mortality.     

新疆维吾尔族成人支气管哮喘的影响因素研究

摘要:目的　探讨新疆乌鲁木齐市维吾尔族人群成人支气管哮喘的影响因素。方法　本研究采用成组匹配病例对照研究方法,病例组为新疆医科大学第一附属医院呼吸内科在2014年1-12月确诊的维吾尔族支气管哮喘成人患者（n＝120例）,对照组为同期体检中心健康维吾尔族体检者（n＝126例）,两组在年龄、性别相匹配。采用问卷调查的方法收集相关暴露资料,并采用单因素分析及多因素非条件Logistic回归模型分析成人支气管哮喘影响因素。结果　多因素Logistic回归分析显示,吸烟（OR＝1.88,95% CI:1.28～2.96）、家族支气管哮喘史（OR＝6.20,95% CI:2.10～18.31）、家中铺有纯毛地毯数量多（OR＝1.87,95% CI:1.18～2.95）,睡眠质量（OR＝1.46,95% CI:1.22～1.75）,患慢性支气管炎（OR＝13.43,95% CI:6.65～25.34）及过敏性鼻炎（OR＝6.27,95% CI:3.63～10.81）是维吾尔族成人支气管哮喘的主要影响因素。结论　维吾尔族成人支气管哮喘是生活方式、环境及遗传等多种因素共同作用的结果,应加强对相关影响因素的预防及治疗,减少哮喘的发生,改善哮喘患者生活质量。     

Human epidermal growth factor receptor 2 oncoprotein expression in breast cancer patients from central Anatolia, Turkey

Aim:   Human epidermal growth factor receptor 2 (HER2) overexpression is associated with poor prognosis and the frequency of HER2 positivity in breast cancer patients varies among different regions of the world. We studied HER2 expression in Turkish breast cancer patients.
Methods:   HER 2 expression was evaluated immunohistochemically in 107 breast cancer patients. HER2 expression was reported as negative or positive (3+) according to cellular membrane staining characteristics. The frequency of HER2 overexpression, distribution according to clinical characteristics, effect on survival and effect of chemotherapy on survival in relation to HER2 overexpression was evaluated.
Results:   The median age of patients was 49 years (range 27–76). HER2 was 3+ in 34 patients (31.8%). There was no significant difference in age, menopausal status, histopathology, lymph node involvement, stage and estrogen and/or progesterone receptor positivity in relation to HER2 expression. Forty-three patients (40.2%) relapsed and 21 patients (19.6%) died during the follow-up period. There was no significant difference in the relapse rate, distribution of relapse sites and death rate in relation to HER2 expression. The 3- and 5-year disease free survival rates were 67.1 and 40.5%, and the overall survival rates were 87.5 and 66.1%, respectively. Survival rate and calculated survival time were relatively shorter in HER2 3+ patients than in non-HER2 3+ patients, but these differences were not statistically significant. HER2 status did not affect survival period according to chemotherapy group.
Conclusion:   Immunohistochemistry findings of HER2 expression in Turkish breast cancer patients were similar to those found in the published reports. A shorter survival period was observed in HER2 3+ patients, but the difference was not statistically significant.     

静心电针法治疗围绝经期综合征临床研究

目的:观察静心电针法治疗围绝经期综合征的临床疗效。方法:将符合标准的围绝经期患者60例随机分为治疗组(30例)和对照组(30例)。治疗组给予静心电针法治疗,对照组给予克龄蒙治疗,均治疗3个周期。分别于治疗前、治疗1个月、治疗3个月(即治疗结束)、治疗后3个月及治疗后6个月进行随访,采用改良的Kupperman指数(KI)进行症状评分,并于治疗前、治疗结束各检测1次血清雌二醇(E2)、卵泡刺激素(FSH)、黄体生成激素(LH)。结果:治疗组和对照组的总有效率比较差异无统计学意义(90.00%vs.93.33%,P>0.05)。2组KI评分,治疗后各时间点与治疗前比较差异均有统计学意义(P<0.01),2组之间各时间点差异无统计学意义(P>0.05),2组在治疗期间,KI均有下降,当治疗结束后3个月与6个月时,KI评分稍有上升,对照组上升稍多,但2组之间差异无统计学意义(P>0.05)。2组治疗后,性激素水平均得到改善(P<0.01),但2组之间差异无统计学意义(P>0.05)。结论:静心电针法治疗围绝经期综合征,安全、疗效好,值得推广应用。
