人工髋关节置换术后脂肪栓塞综合征的观察与护理

笔者报道人工髋关节置换术后脂肪栓塞综合征的护理措施认为重视氧饱和度及动脉血氧分压监测，注意观察中枢神经系统症状和呼吸系统症状，及时发现并纠止低氧血症，对不同的病人制定不同护理方案，严密观察病情，及时掌握病情变化：是护理的关键。     

全营养素混合液(TNA)在肠外营养的应用

脂肪乳剂、葡萄糖、氨基酸、电解质、维生素及微量元素按一定程序混合配成10种全营养素混合液。在4℃14天贮存期内,10种混合液的pH和渗透压变化不大,不同混合液在不同时期的脂粒平均直径变化为0.3135±0.1012μm～0.4813±0.1893μm,94.93％脂粒的直径<0.6μm,无直径>6μm的脂粒,细菌培养阴性。74例共输全营养素混合液1,796次,无不良临床反应和异常实验室检查结果;用1周以上者大都显示氮平衡改善,用2周以上者血清转铁蛋白和白蛋白浓度可有不同程度升高。     

Diet and premenopausal bilateral breast cancer: A case-control study

We investigated associations between diet and premenopausal bilateral breast cancer in a familial matched case-control study. We studied 140 cases from population-based registries in Los Angeles County (California) and Connecticut, and from the major hospitals in the southern parts of the Province of Quebec. Unaffected sisters of the cases served as matched controls (222 total). Dietary intake were assessed with a food frequency questionnaire. Total fat, monounsaturated fat, polyunsaturated fat, oleic acid, and linoleic acid intake was inversely associated with premenopausal bilateral breast cancer risk. Consumption of carbohydrates (and sweetened beverages) was associated with an increased risk. We observed no associations for dietary fiber, antioxidants, or major food groupings, but we did observe inverse associations for intake of low fat dairy products and tofu. These findings suggest that monounsaturated and polyunsaturated fats, as well as soy foods, might reduce the risk of premenopausal bilateral breast cancer.     

The role of low fat diets in the management of gall-bladder disease

This paper presents the results obtained from 87 questionnaires completed by dietitians about the dietary management of gall-biadder disease. Of the patients referred to the dietitians, 86% were referred by surgeons. Of the dietitians that responded 77% thought that there was a role for low fat diets in the management of these patients; 92% would advise a low fat diet to help avoid pain, and 11% would advise a low fat diet to patients with gall-bladder disease who did not have pain, steatorrhoea or obesity.
The paper reviews the available evidence concerning the effect of dietary fat on the gall-bladder; it is concluded that, at present, there is little data to support the therapeutic use of a low fat diet for individuals with gall-stones.     

腮腺外面神经颊支的应用解剖研究

目的:观测面神经颊支出腮腺后的各级分支,为相关外科手术提供解剖学依据。方法:10例(20侧)防腐人头标本,描述面神经颊支出腮腺后的走行、定位及层次。结果:面神经颊支出腮腺后分为2～4支,均走行在SMAS筋膜下;颊Ⅰ、颊Ⅱ恒定出现,其一级分支距腮腺导管分别为(1.1±0.5)cm及(0.5±0.3)cm,且分别向前走行(1.3±0.9)cm及(1.8±0.5)cm后发出二级分支。结论:面神经颊支较为恒定,在面瘫治疗中健侧面神经颊支的二级分支可以作为受体神经,可不损伤面神经颊支主干。面神经颊支的分布及走行也可指导除皱术、扩张器植入、瘢痕切除等手术的剥离范围,不致产生并发症。     

脂必妥胶囊联合疏肝祛瘀中药治疗脂肪肝的临床观察

[目的]探讨脂必妥胶囊联合疏肝健脾、化痰祛瘀中药治疗脂肪肝的临床疗效。[方法]将45例脂肪肝患者随机分为两组,治疗组25例,使用脂必妥胶囊联合疏肝健脾、化痰祛瘀中药治疗3月;对照组20例,单用脂必妥胶囊治疗3月,观察患者治疗前后血清丙氨酸转氨酶（ALT）、甘油三酯（TG）、血清总胆固醇（TC）的变化。[结果]治疗组总有效率为84.0%,而对照组仅70.0%;治疗组TG、TC治疗后下降明显;治疗后与对照组治疗后比较也下降明显。[结论]脂必妥胶囊联合疏肝健脾、化痰祛瘀中药治疗脂肪肝是一种有效的方法。     

Femoral pseudo-hernias

Before surgical intervention in the femoral area, doctors should be mindful of two situations in which surgery is not indicated and, in fact, may cause harm. Electronic Publication
