糖尿病护理门诊在糖尿病健康教育中的作用探究

目的:研究糖尿病护理门诊在糖尿病健康教育中作用.方法:取78例糖尿病患者,其中39例患者进行常规护理为对照组,39例患者进行糖尿病门诊护理为观察组,对比2组患者护理后自我管理能力和血糖指标.结果:观察组自我管理能力均高于对照组(P<0.05).观察组血糖指标均低于对照组(P<0.05).结论:向糖尿病患者进行健康教育时,糖尿病门诊护理的应用,可以科学创建护理档案,明确随访策略,提升糖尿病的管理水平,使患者具有较强自我管理能力,同时降低其血糖指标.     

临床检验不合格血液标本产生原因及质量改进研究

目的:分析临床检验不合格血液标本的原因为何,研究相应的质量改进方法。方法:本课题自我院检验血液标本样本中抽取140份,其中2018年2月~2019年3月的70份命名成对照组,2019年4月~2020年3月的70份命名成试验组,前一组未进行质量改进,后一组进行质量改进,比较检验结果有何不同。结果:试验组这组的检验标本不合格率要比对照组那组的检验标本不合格率低,数据上是P<0.05的情况,即表明有统计学意义。结论:凝血反应、溶血反应、样本问题、送检失误、抗凝不全等是导致临床检验不合格血液标本的原因所在,实施质量改进可将血液标本质量提高。     

南充市社区中老年人群血脂血糖现状水平分析

【摘要】 目的 了解社区中老年人群的血脂、血糖现状水平，探讨其与性别和年龄的关系，为本地区心脑血管疾病、糖尿病等疾病的防治提供诊疗依据。方法 对我市38078名社区居民采集清晨空腹血清标本，检测血糖（GLU）、甘油三酯（TG）、总胆固醇（TC）、高密度脂蛋白胆固醇（HDL C）和低密度脂蛋白胆固醇（LDL C）的结果，并对其进行年龄、性别分组统计分析。结果 不同性别和年龄组间的血脂、血糖水平差异有统计学意义（P＜005），74~89岁年龄组血脂、血糖总体水平高于其他各年龄组（P＜005）；女性血脂水平普遍高于男性（P＜005）。结论 中老年人群血脂、血糖异常率高，应定期对中老年人进行血脂、血糖监测，开展宣传教育活动，提高自我保健意识，预防高血脂、高血糖的发生和发展。     

Assessing the impact of blood alcohol concentration on the rate of in-hospital mortality following traumatic motor vehicle crash injury: A matched analysis of the National Trauma Data Bank

Background

The purpose of this study was to compare the outcomes of trauma patients who were injured in a motor vehicle crash and tested positive for alcohol upon hospital arrival versus those who tested negative.

A prime-boost concept using a T-cell epitope-driven DNA vaccine followed by a whole virus vaccine effectively protected pigs in the pandemic H1N1 pig challenge model

Influenza A virus (IAV) vaccines in pigs generally provide homosubtypic protection but fail to prevent heterologous infections. In this pilot study, the efficacy of an intradermal pDNA vaccine composed of conserved SLA class I and class II T cell epitopes (EPITOPE) against a homosubtypic challenge was compared to an intramuscular commercial inactivated whole virus vaccine (INACT) and a heterologous prime boost approach using both vaccines. Thirty-nine IAV-free, 3-week-old pigs were randomly assigned to one of five groups including NEG-CONTROL (unvaccinated, sham-challenged), INACT-INACT-IAV (vaccinated with FluSure XP® at 4 and 7 weeks, pH1N1 challenged), EPITOPE-INACT-IAV (vaccinated with PigMatrix EDV at 4 and FluSure XP® at 7 weeks, pH1N1 challenged), EPITOPE-EPITOPE-IAV (vaccinated with PigMatrix EDV at 4 and 7 weeks, pH1N1 challenged), and a POS-CONTROL group (unvaccinated, pH1N1 challenged). The challenge was done at 9 weeks of age and pigs were necropsied at day post challenge (dpc) 5. At the time of challenge, all INACT-INACT-IAV pigs, and by dpc 5 all EPITOPE-INACT-IAV pigs were IAV seropositive. IFNγ secreting cells, recognizing vaccine epitope-specific peptides and pH1N1 challenge virus were highest in the EPITOPE-INACT-IAV pigs at challenge. Macroscopic lung lesion scores were reduced in all EPITOPE-INACT-IAV pigs while INACT-INACT-IAV pigs exhibited a bimodal distribution of low and high scores akin to naïve challenged animals. No IAV antigen in lung tissues was detected at necropsy in the EPITOPE-INACT-IAV group, which was similar to naïve unchallenged pigs and different from all other challenged groups. Results suggest that the heterologous prime boost approach using an epitope-driven DNA vaccine followed by an inactivated vaccine was effective against a homosubtypic challenge, and further exploration of this vaccine approach as a practical control measure against heterosubtypic IAV infections is warranted.     

枸橼酸咖啡因与氨茶碱对早产儿不同时相血糖值的影响比较

目的观察并比较枸橼酸咖啡因及氨茶碱对早产儿不同时相血糖的影响程度。方法选择新生儿监护室诊断为原发性呼吸暂停的出生胎龄＜34周的早产儿172例，采用随机数字表法分为咖啡因组与氨茶碱组各86例。比较两组早产儿用药前及用药后15、30min、1、1.5、2、4、6、12、12.5、24.5、36.5和48h血糖的变化。结果两组早产儿用药后除6、12和48h血糖值比较差异均无统计学意义（均P＞0.05），其他用药后时相比较差异均有统计学意义（均P＜0.05）。咖啡因组早产儿用药后30min血糖值上升，至1h达峰值，后逐渐回落；用药后30min、1、1.5、2及24.5h血糖值与用药前比较差异均有统计学意义（均P＜0.05）。氨茶碱组早产儿用药后血糖值上升，30min达峰值，后逐渐回落；用药后15、30min、1、1.5、2、4、6、12.5、24.5、36.5h血糖值与用药前比较差异均有统计学意义（均P＜0.05）。结论枸橼酸咖啡因可引起早产儿血糖升高，但升高幅度较氨茶碱小、持续时间也较短。
