背部供皮区修复大面积皮肤缺损

目的探讨应用背部供皮区修复大面积皮肤缺损的优点。方法对Ⅲ°烧伤、巨大体表肿瘤切除、四肢皮肤撕脱伤及其他原因造成的大面积皮肤缺损的40例患者,根据缺损的部位和大小,用鼓式取皮机在患者背部切取相应的中厚皮片,移植修复缺损。结果术后随访患者1年,所有移植皮片均成活。背部供皮区愈合良好,瘢痕增生轻微,不影响外观。结论于背部取皮其供皮面积大、部位隐蔽,且背部真皮层较厚,取皮后愈合快,愈合后患者能自行平卧加压,避免瘢痕增生。是较理想的修复大面积皮肤缺损的手术方法。

Prior depression and incident back pain among military registered nurses: A retrospective cohort study

BackgroundOccupational back pain rates are substantial among registered nurses, and nurses also report high rates of depression. The role of depression as a potential predictor of back pain among nurses appears understudied.ObjectivesThe objective of the study was to determine whether a history of depression predicted incident back pain in a population of military registered nurses when controlling for relevant risk factors.DesignWe employed a retrospective cohort approach using longitudinal data in which gender-specific subject groups were followed from the beginning of duty as a registered nurse to the occurrence of an outcome, or to censoring due to completion of service or the end of available data.ParticipantsThis study included all United States Army registered nurses who began work during 2011–2014 without evidence of prior back pain in clinical records.MethodsData from automatically-collected medical and administrative sources were combined and used to provide 2134 person-years of observation on 1248 individuals. These data were organized at the person-month level in a panel data structure to support discrete-time multivariable logistic regression models. The models examined the relationships between prior depression, Body Mass Index, the presence of prior combat duty and selected control variables and the outcome, the incident occurrence of back pain.ResultsThe incidence rate of back pain was 18.6 per 100 person-years and the period prevalence was 31.7%. Prior depression was a statistically-significant predictor of incident back pain among female subjects (odds ratio [OR]: 1.75, 95% confidence interval [CI]: 1.08–2.83, P-value < 0.05). Body Mass Index of 30 kg/m² or greater, prior combat deployments, and age 36 years or older was each associated with back pain for male and female nurses.ConclusionsThe study’s findings provide the first evidence of a temporal link between antecedent depression and later back pain among female military nurses. High Body Mass Index was found to be a further, modifiable risk factor for back pain in this population.     

Clinical Study of Acupoint Injection in Treating Lumbar Intervertebral Disc Protrusion

目的：观察穴位注射治疗腰椎间盘突出症的临床疗效。方法：将156例腰椎间盘突出症患者随机分为观察组80例（弥可保注射液）和对照组76例（维生素B12注射液），采用穴位注射受压神经根相应节段夹脊穴的方法。结果：观察组有效率为86．3％，对照组有效率为78．9％，两组疗效比较P〈0．01，差异有统计学意义。结论：“弥可保”注射液穴位注射治疗腰椎间盘突出症的临床疗效明显高于维生素B12穴位注射。     

Observation of the therapeutic effect of treating lumbar intervertebral disc protrusion by acupuncture therapy

目的：观察针刺病变腰椎两侧经穴治疗腰椎间盘突出症的临床疗效。方法：将180例腰椎间盘突出症患者随机分为治疗组60例，针刺对照组60例，西药对照组60例，治疗20天后进行疗效比较。结果：治疗组有效率96．7％，针刺对照组为80．0％，西药对照组为81．7％，治疗组与对照组差异有显著性意义（P〈0．05）。结论：针刺病变腰椎两侧经穴是治疗腰椎间盘突出症的有效方法。     

Acupuncture treatment for Subacute Non-specific Low Back Pain-A Retrospective Cohort Study in the Role of the Back Exercise in Acupuncture Services for Low Back Pain Sufferers

目的研究腰部的锻炼方法与针刺疗效的内在关系,以揭示部分腰痛病人针灸治疗恢复较慢的原因.方法采用回顾性调查研究方法.70例被诊断为腰痛的患者按顺序性抽样方法分为两组.观察组44例采用针刺治疗加锻炼的方法,对照组26例仅针刺治疗.根据针刺治疗后1年内的复发率比较两组间的差异.结果与结论背部锻炼是一个危险因素,它和腰痛的频繁发作有关.而针刺治疗是一种对亚急性非特异性腰痛的有效治疗方案.
