新型管理模式在护理实习教学管理中的应用探讨

目的探讨在进行护理实习教学管理期间新型管理模式应用可行性。方法选择我院2018年1月-2019年2月102例实习护生作为试验对象;数字奇偶法分组后探究每组教学管理模式;对照组(51名):选择传统护理教学管理模式展开;试验组(51名):选择新型护理教学管理模式展开;比较两组护实习护生行为规范合格率、平均业务学习出勤率以及教学满意度评分结果。结果试验组实习护生规范合格率(98.04%)高于对照组(64.71%)(P<0.05);试验组实习护生平均业务学习出勤率(98.04%)高于对照组(62.75%)(P<0.05);试验组实习护生各项教学满意度评分均高于对照组(P<0.05)。结论医院实习护生在接受新型护理实习教学管理后,对于规范合格率的提升,平均业务学习出勤率的提升以及教学满意度评分的提升,均获得显著效果,最终为医院实习护生的学习效率以及护理安全提升奠定了基础。     

Perioperative management of diabetes

Diabetes is a complex, chronic metabolic disorder affecting approximately 9.3% of the adult population with the estimated number of adults with diabetes worldwide having more than tripled since 2000. This increase has largely been attributed to global urbanization and lifestyle changes. Diabetes affects 10–15% of the surgical population. These patients are frequently elderly, have complex medical co-morbidities and present for both high-risk elective and emergency surgery. This multisystem disease poses a significant challenge to both anaesthesia and surgery with patients with diabetes demonstrating higher morbidity and mortality rates compared to their non-diabetic counterparts. It is crucial that good glycaemic control is maintained throughout the perioperative period as this has been shown to correlate with positive patient outcomes. It is well-recognized that a co-ordinated, multidisciplinary approach aimed at optimizing every point in the patient pathway from GP referral to post-discharge care is required to obtain the best outcomes for the surgical patient with diabetes. The anaesthetist has a key role in the perioperative diabetes multidisciplinary team. Patients themselves are well experienced in manging their own diabetes and should be involved in doing so whenever possible.     

Convergence and attractivity of memristor-based cellular neural networks with time delays

This paper presents theoretical results on the convergence and attractivity of memristor-based cellular neural networks (MCNNs) with time delays. Based on a realistic memristor model, an MCNN is modeled using a differential inclusion. The essential boundedness of its global solutions is proven. The state of MCNNs is further proven to be convergent to a critical-point set located in saturated region of the activation function, when the initial state locates in a saturated region. It is shown that the state convergence time period is finite and can be quantitatively estimated using given parameters. Furthermore, the positive invariance and attractivity of state in non-saturated regions are also proven. The simulation results of several numerical examples are provided to substantiate the results.

至阳八阵穴隔附子饼灸治疗糖尿病胃轻瘫临床研究

目的观察至阳八阵穴隔附子饼灸治疗脾胃气虚型糖尿病胃轻瘫的疗效及对胃泌素(GAS)、胃动素(MTL)和血管活性肠肽(VIP)水平的影响。方法86例脾胃气虚型糖尿病胃轻瘫患者随机分为对照组和治疗组,每组43例。治疗组给予至阳八阵穴隔附子饼灸;对照组口服枸橼酸莫沙必利片。治疗12周后观察胃轻瘫主要症状指数量表症状积分改善情况、胃排空率及血清GAS、MTL、VIP水平。结果治疗组治疗后在胃轻瘫主要症状指数量表症状积分及胃排空率方面明显高于对照组,差异均有统计学意义(P<0.05)。治疗组治疗后血清GAS、MTL水平明显高于对照组,血清VIP水平明显低于对照组,差异均有统计学意义(P<0.05)。治疗组总有效率为90.7%,明显高于对照组的72.1%(P<0.05)。结论采用至阳八阵穴隔附子饼灸能快速促进糖尿病胃轻瘫患者胃功能的恢复,改善症状和体征,其作用机制可能与升高患者血清GAS和MTL水平,降低VIP水平有关。     

皮肤再生医疗技术治疗糖尿病足溃疡疗效分析
