手术室细节护理管理在医院感染控制中的应用评价

目的探讨手术室细节护理管理在医院感染控制中的应用效果。方法选定2017年1月-2018年3月该院收诊的160例手术室患者,按照管理方法的不同分为观察组(细节护理管理)80例与对照组(传统护理管理)80例,比较两组手术室患者的护理质量、并发症发生率、感染发生率、护理满意度、收缩压。结果观察组护理管理后的护理安全(82.23±6.14)分、体征监测(93.46±6.23)分、体位协助(87.32±4.65)分、器械准备(91.57±6.21)分、文书记录(90.24±4.92)分、护理满意率(98.75%)均高于对照组(P<0.05);观察组护理管理后的并发症发生率(2.50%)、感染发生率(1.25%)、收缩压(121.37±6.26)mmHg均低于对照组(P<0.05)。结论细节护理管理方法可有效提高手术室患者的护理满意度,减少其感染情况,值得推广使用。     

Body weight in patients with Parkinson's disease.

There is some evidence suggesting that Parkinson's disease (PD) patients exhibit lower body weight when compared to age-matched healthy subjects. Low body mass index (BMI) is correlated with low bone mineral density, both of which are major risk factors for hip fractures. Possible determinants of weight loss in PD patients include hyposmia, impaired hand-mouth coordination, difficulty chewing, dysphagia, intestinal hypomotility, depression, decreased reward processing of dopaminergic mesolimbic regions, nausea, and anorexia as the side effects of medication, and increased energy requirements due to muscular rigidity and involuntary movements. It is unclear whether PD patients in general, or only a subgroup of those affected, definitely show lower BMI in the advanced stages of the disease. We therefore recommend that the body weight of PD patients be monitored monthly as the disease progresses, and that a patient's nutrition should be supplemented with sufficient amounts of vitamin D and calcium to reduce the risk of hip fractures and strengthen bone density. Because meal times may coincide with unpredictable off periods associated with akinesia and impaired hand-mouth coordination, PD patients also need flexible food schedules that accommodate the associated symptoms of this disease.     

Laparoscopic adjustable gastric banding for patients with body mass index of ≤35 kg/m

BACKGROUND: Many mild-to-moderately obese individuals (body mass index [BMI] 30-35 kg/m(2)) have serious diseases related to their obesity. Nonoperative therapy is ineffective in the long term, yet surgery has never been made widely available to this population. METHODS: Between 1996 and 2004, 93 patients with a BMI of 30-35 kg/m(2) underwent laparoscopic adjustable gastric banding with the LAP-BAND. All patients were referred by their primary physician, entered into a comprehensive bariatric surgery program at one Australian center, and operated on by one surgeon. Data on all patients were collected prospectively and entered into an electronic registry. The study parameters included preoperative age, gender, BMI, presence of co-morbidities, percentage of excess weight loss, and resolution of co-morbidities. RESULTS: The mean age was 44.6 years (range 16-76), mean weight was 98 kg, and the mean BMI was 32.7 kg/m(2) (range 30-34). Of the 93 patients, 42 (45%) had co-morbidities, including asthma, diabetes, hypertension, and sleep apnea. The proportion of patients in follow-up was 79%, 85%, and 89% at 1, 2, and 3 years, respectively. The mean weight was reduced to 71 kg at 1 year, 72 kg at 2 years, and 72 kg at 3 years. The mean BMI was reduced to 27.2 +/- 2.2, 27.3 +/- 3.1, and 27.6 +/- 3.7 kg/m(2), respectively, and the mean percentage of excess weight loss was 57.9% +/- 24.5%, 57.6 +/- 29.3%, and 53.8% +/- 32.8% at 1, 2, and 3 years, respectively. At 3 years, the BMI was 18-24 kg/m(2) in 34%, 25-29 kg/m(2) in 51%, and 30-35 kg/m(2) in 10%. At 3 years, the percentage of excess weight loss was <25% in 10%, 25-50% in 24%, 50-75% in 51%, and >75% in 10%. The co-morbidities improved or completely resolved in most patients. No mortality occurred. CONCLUSION: We are very encouraged by this series of low BMI patients treated with the LAP-BAND. Their weight loss has been good, the complications have been minimal, and the co-morbidities have partially or wholly resolved. With additional study, it is reasonable to expect the weight guidelines for bariatric surgery to be altered to include patients with a BMI of 30-35 kg/m(2).     

胰腺导管癌中血管生成、细胞增殖指数、DNA倍性检测的临床意义

目的:探讨血管生成、细胞增殖指数、DNA倍性在胰腺导管癌发生、发展中的作用及临床意义。方法:对29例胰腺导管癌和7例慢性胰腺炎患者的石蜡包埋标本作苏木精鄄伊红(HE)染色,CD34、Ki67免疫组织化学染色,镜下计算微血管密度(MVD)及Ki67阳性细胞比例,同时用流式细胞仪(FCM)检测细胞核DNA倍性,计算异倍体出现率及S期比例,并结合临床病理资料对各项指标作相关分析。结果:胰腺导管癌和慢性胰腺炎都有较多的新生血管。MVD值在胰腺导管癌高、中、低分化3组之间差异无显著性。按肿瘤直径分为≤1.5cm、1.6～2.9cm、≥3cm3组,此3组间MVD值、Ki67阳性细胞百分率、DNA异倍体出现率及肿瘤周围有无浸润的差异都非常显著(P<0.01)。肿瘤越大,MVD值、Ki67阳性细胞百分率及DNA异倍体出现率越高。结论:胰腺导管癌的发生、发展伴血管生成和DNA合成增加,联合测定MVD、Ki67阳性细胞百分率、DNA倍型可能为胰腺导管癌临床预后预测提供辅助参考指标。

An experimentally supported, mathematical explanation of the gas chromatographic elution behaviour of the long-chain carbon members of the homologous series

By substituting the saturated vapour phase tension of the pure normal hydrocarbons described by the Clausius-Clapeyron law into the accepted expression of the specific retention volume (V_g,T), a theoretically coherent and relatively simple mathematical evidence of the elution behaviour of the homologous members has been deduced. It gives exponential retention time dependence on carbon number for isothermal, and nearly equidistant (i.e., approximately linear retention-time dependence on carbon number) elution for linear temperature programmed gas chromatographic runs. The final equations are in close correlation with the experimental results. Special emphasis is placed on the fact that a good approximation—not strict physical laws—have been found.     

体重指数分级标准应用方法的探讨

目的探讨按照体重指数分级标准计算出的体重值应用表的实用价值。方法将身高作为选定变量,其变量值间距为1 cm,按照体重指数分级标准上、下限值,分别乘以身高2(m2),即求出相对应的体重(kg),依此制成应用表。判定时依据身高和实测的体重,对照应用表得出其体重指数分级范围。结果制成并列出以体重值查对其相对应危险值应用表。结论本查对表适用于大规模的预防性健康体检。在人体生长发育阶段能做到自身动态监测,对早期预防肥胖症具有积极作用。     

亚硒酸钠对顺铂致人体淋巴细胞增殖抑制的拮抗作用

目的 检测亚硒酸钠是否能够削弱或解除顺铂对植物血球凝激素(PHA)刺激的人体外周血淋巴细胞的增殖抑制。方法 用顺铂和亚硒酸钠单独或联合处理PHA刺激的人体外周血淋巴细胞，顺铂(0．05，0．20，0．50mg／L)在细胞培养24h时加入，亚硒酸钠(0．05mg／L)在不同处理中分别在细胞培养开始时加入或与顺铂同时加入；培养72h后检测转化淋巴细胞的有丝分裂指数。结果0．05mg/L亚硒酸钠在培养开始时加入，PHA刺激转化的淋巴细胞有丝分裂指数较对照增长42．8％(P＜0．05)，与顺铂同时加入，有丝分裂指数增长13．7％(P＞0．05)。0．05与0．20mg/L顺铂处理细胞，有丝分裂指数未发生显性改变，当顺铂剂量为0．50mg/L时，细胞有丝分裂指数较对照降低54．5％(P＜0．001)。亚硒酸钠预处理细胞可以解除0．50mg/L顺铂所致的细胞增殖抑制，使有丝分裂指数恢复正常，但亚硒酸钠与顺铂同时加入时，被顺铂抑制的有丝分裂指数只能部分提高。结论0．05mg/L亚硒酸钠单独作用于淋巴细胞可直接促进细胞增殖，与顺铂联合处理细胞时，可降低顺铂毒性，拮抗顺铂的抗增殖作用。亚硒酸钠在细胞培养开始时加入培养体系效果更佳。     

Reliability of the Functional Independence Measure with Occupational Therapists

This paper reports an inter-rater reliability study on the Functional Independence Measure (FIM). The FIM measures inpatient burden of care, as reflected in 18 self care items, rated on a seven point scale from dependent to independent. The subjects were 40 occupational therapists, divided according to experience with the FIM and randomly assigned to a FIM training or non-training group. Subjects rated video tapes of four stroke patients on transfers, bathing, dressing, grooming, toileting and eating items from the FIM. Rater consensus was calculated using the intraclass correlation coefficient (ICC), percentage agreement and a measure of disagreement. Rating accuracy was measured by comparisons with an expert rater. Ratings were most reliable when done by clinicians with no prior FIM experience, from the FIM training group. It is strongly recommended that all clinicians undergo FIM training before using this tool to ensure acceptable reliability.
