Objective To observe the clinical effect of lactase on rotavirus enteritis in infants and young children. Methods From January 2015 to May 2017,a total of 120 infants and young children with rotavirus enteritis were selected in the Department of Pediatrics,Naval Authority Clinics,and they were divided into A group,B group and C group according to random number table,each of 40 cases.Based on conventional treatment,patients in A group kept customary diet,patients in B group received free-lactose milk powder for 2 weeks,while patients in C group kept customary diet and received lactase for 2 weeks.Clinical effect,diarrhea frequency before treatment and 4 days after treatment,and diarrhea stopping time were compared in the three groups,compliance and incidence of adverse reactions was observed in C group.Results Clinical effect in B group and C group was statistically significantly better than that in A group,respectively(P<0.05),while no statistically significant differences of clinical effect was found between B group and C group(P>0.05).No statistically significant differences of diarrhea frequency was found in the three groups before treatment(P>0.05);4 days after treatment,diarrhea frequency in B group and C group were statistically significantly less than that in A group,respectively(P<0.05),while no statistically significant differences of diarrhea frequency was found between B group and C group(P>0.05).Diarrhea stopping time in B group and C group was statistically significantly shorter than that in A group,respectively(P<0.05),while no statistically significant differences of diarrhea stopping time was found between B group and C group(P>0.05).The compliance was good in C group, no one occurred any obvious adverse reactions.Conclusion Lactase has similar clinical effect with free-lactose milk powder in treating infants and young children with rotavirus enteritis,can effectively relieve the lactose intolerance without change the customary diet,and the compliance is good.

Objective To understand the development and current status of low back pain among the submarine crew,and analyze the influencing factors. Methods The general condition, professional,life style,working condition and low back pain status of submarine crews were collect-ed by using questionnaires. Only 423 submarine crews in a naval unit were effective in our research. According to admission,143 submarine crews with low back pain enrolled were used visual analogue scale (VAS), special-purpose physical examination and the disability degree based on the Ad-vanced Oswestry Disability Index (ODI). Results The incidence of low back pain in 423 subma-rine crews was 33.81%. There were significantly difference in VAS of four groups (P<0.05). The score of pain intensity was affected mostly in the group of ≥9 years (8.52±0.68). The total score of ODI in crew of low back pain was 37.92±3.22 points. The professional,service lives, the dura-tion of symptom,and injury had an influence on low back pain(P<0.05). Conclusion In subma-rine crew of low back pain, the incidence was higher, the spinal function was worse, and discom-forts influence the daily life. In order to reduce the crew's discomforts,we should give them health education and improve their awareness of this disease,and set up health habits of life.

目的 探讨潜艇部队官兵下腰痛患病情况及危险因素,为有效防治该疾病提供科学依据.方法 对海军某潜艇基地体检官兵进行问卷调查,项目包括一般情况、服役年限、从事专业、生活习惯及下腰痛情况等.按照纳入标准将官兵分为有下腰痛的腰痛组,无下腰痛的对照组,数据采用Logistics回归模型进行分析研究.结果 共调查潜艇官兵450例,最终有效问卷423份,其中腰痛组143例,对照组280例.潜艇官兵下腰痛的危险因素中以服役年限(OR=1.865)危险性最高,其次是从事专业(OR=1.843)、病程时间(OR=1.802)、外伤史(OR=1.725).结论 潜艇部队官兵下腰痛的发生受服役年限、从事专业及外伤史等因素影响.

目的:探讨针对性康复训练对慢性肩袖损伤的疗效.方法:选取2015年9至2017年9月诊治的符合纳入标准的慢性肩袖损伤患者138例,随机分成对照组和观察组,每组69例.对照组采用超短波治疗、口服抗炎止痛药物及肩关节松动技术,观察组在对照组治疗基础上增加针对性康复训练,包括肩袖损伤肌群激活、肩胛骨运动控制和肩关节肌肉强化稳定训练.4周后两组患者采用美国加州大学(UniversityofCalifornia–LosAngeles'UCLA)肩袖损伤专业评分系统进行各项分值比较及疗效评价.结果:两组患者治疗后在疼痛、肩关节功能、主动前屈力量及主动前屈活动度分值较治疗前均有显著提高,而两组在治疗后比较,观察组各项分值明显高于对照组(P<0.05);观察组总有效率(94.2％)明显优于对照组(69.6％),具有显著差异(P<0.05).结论:采用针对性康复训练治疗慢性肩袖损伤,能有效的促进肩关节功能的恢复,同时对稳定肩关节具有积极意义,值得临床推广应用.

随着国家医疗体制改革的不断深入,物流业的迅速发展,旧的药库管理模式已难以适应现代化医院的管理要求,实现高效、科学的药品库存管理,促使医院药品供应管理科学化、准确化、经济化是当前医院药品库存管理的迫切需要.在医院信息系统(HIS)的支持下,零库存管理成为实现这一目标的有效方式.零库存管理不但能减少药库日常管理需要投入的人力、物力和财力,降低库存管理的成本,同时还可明显提高药品的周转率,激活流动资金[1].2017年4月,某部尝试实施药品零库存管理,通过1年的实践,现总结如下.

Objective To understand the features of military training-related injuries that occurred among naval officers and related risk factors, so as to provide effective prevention and treatment measures against military training-related injuries.Methods Four hundred and thirty-eight officers were recruited and a face-to-face questionnaire survey was made for the study.The subjects were divided into 2 groups ( the injury group and the non-injury group) by depending on whether or not they had training-related injury. Then, differences in the general conditions, the awareness of prevention against training-related injury, attitude and treatment behavior were analyzed between the 2 groups.Results In the naval unit undergoing military training, personnel with the an age range between 25 and 34 had the highest rate of training-related injury(56.3%), and there was statistical significance in the composition of the age between the injury group and the non-injury group (P<0.01).75.57%of the naval officers thought that training-related injury was re-lated with technical manipulations, and 81.96% of them knew emergency treatment methods when injuries occurred.The number of people who failed to do warming-up activities and those who persisted in training when signs of discomfort or fatigue-induced injury oc-curred for the injury group was significantly higher than that of the non-injury group (P<0.05).Conclusion In military training, the occurrence of injury was closely related with insufficient warming-up activities and irregular manipulations, and at the same time, insuffi-cient knowledge about the prevention of training-related injury and improper behavior were also important factors for training-related injury.

Objective To study the changes of the cervical spine curvature and the morphous and provide a diagnostic evidence for the sedentary.Methods According to seeking clinic treatments,194 patients with neck discomfort or were diagnosis of cervical disease in our hosiptal from Mach 2004 to March 2009 divided into four groups: normal,lordosis,straight and kyphotic,all sitting for 4 hours every day.Results Compared to the normal group,the sagittal diameter ratio and the deformation index of the straight group and kyphotic group,the differences were statistically significant(P < 0.05).Conclusion The change of cervical spine curvature is dependent with cervical spine deformation,which may be a factor for cervical spondyiosis development.
