红细胞压积与白蛋白差值在继发性腹腔感染患者病程中的变化

  目的   通过观察HCT和ALB差值在腹腔感染患者治疗过程中的变化，为腹腔感染患者的准确治疗提供一定的指导。   方法   选取2018年1月至2018年12月昆明医科大学第一附属医院收治的各类腹腔感染手术患者共计106名，按手术时间分为术前、术后12 h、术后1 d术后2 d、术后7 d、术后14 d和术后21 d 7组（n = 106），记录患者性别、年龄；收集患者上述各时间点患者的红细胞压积、血浆白蛋白，计算HCT-ALB差值。再根据临床结局分为术后好转组和死亡组。比较每组HCT、ALB和HCT-ALB差值。   结果   与手术前相比，术后12 h、术后1 d、术后2 d和术后7 d，患者HCT和ALB下降，HCT-ALB增大（P < 0.05）；与手术前相比，术后14 d，HCT和ALB下降，（P < 0.05），HCT-ALB差异无统计学意义（P > 0.05）；与好转组相比，死亡组患者年龄增加（P < 0.05），术前的HCT-ALB增大（P < 0.05）。   结论   腹腔感染患者在手术治疗后毛细血管渗漏加重，这一病理过程可持续7 d以上，死亡患者的毛细血管渗漏更严重。

A novel algorithm for the objective detection of tropical cyclone centres using infrared satellite images

Tropical cyclones (TCs) are one of nature’s most destructive phenomena, and a key element in forecasting TC tracks is the ability to accurately detect TC centres. In this paper, a novel algorithm has been proposed to objectively detect TC centres using infrared satellite images. Pyramid representation and optical flow technique are utilized to construct the cloud motion wind (CMW) field of each cyclone, and thereafter the centre is determined by analysing the constructed CMW field. Ten TCs formed in the Northwestern Pacific Ocean in 2014 have been tested to evaluate the performance of the present method, and TC Halong and Rammasun were analysed in detail as instances. Experimental results comparing with forecast track derived from Unisys Weather show that the proposed method provides an accurate detection of TC centres. The present algorithm has a potential to be employed to assist forecasters to detect TC centres.

抗敏合剂治疗多形性日光疹的临床研究

目的:研究抗敏合剂治疗多形性日光疹的临床疗效。方法:93例患者随机分为治疗组62例和对照组31例。治疗组:口服抗敏合剂50mL/d,2次/d;对照组:口服氯雷他定片10mg/d。两组同时予3%硼酸洗液湿敷,每日2次,每次10min。疗程均为14d。结果:治疗组失访2例,对照组失访1例。治疗组愈显率为68.3%(41/60),对照组愈显率为36.7%(11/30),治疗组优于对照组(P<0.01);治疗后,两组症状评分较治疗前均明显下降,治疗组优于对照组(P<0.05);治疗组在改善靶皮损面积方面优于对照组(P<0.01)。结论:抗敏合剂可以明显改善多形性日光疹的临床症状,安全有效。     

角色扮演法培养护生临床思维能力的研究

[目的]探讨角色扮演教学法在培养高职高专护生临床思维能力方面的作用,以提高教学质量。[方法]采用目的抽样法抽取某高职高专护理学院4个班级167名学生,将4个班级随机分成两组,对照组给予讲授法,试验组给予角色扮演式教学法,教学结束后考察两组学生的临床思维能力。[结果]两组护生基本理论知识和思维的批判性得分差异无统计学意义;基本护理技能、应变能力、沟通能力、思维的独创性方面得分差异有统计学意义(P<0.05)。[结论]角色扮演法教学一方面在培养护生临床思维能力方面作用显著,另一方面也训练护生整体护理能力,推动学生核心能力发展。     

Meta‐analysis of simultaneous versus staged resection for synchronous colorectal liver metastases

Aim: There is no clear consensus on the optimal timing of surgical resection for synchronous colorectal liver metastases (SCLM). This study is a meta‐analysis of the available evidence. Methods: Systematic review and meta‐analysis of trials comparing outcomes following simultaneous resection with staged resection for SCLM published from 1990 to 2010 in PubMed, Embase, Ovid and Medline. Pooled odds ratios (OR) or weighted mean differences (WMD) with 95% confidence intervals (95% CI) were calculated using either the fixed effects or random effects model. Results: Nineteen non‐randomized controlled trials (NRCT) studies were included in this analysis. These studies included a total of 2724 patients: 1116 underwent simultaneous resection and 1608 underwent staged resection. Meta‐analysis showed that shorter hospital stay (P < 0.001) and lower total complication rate (P < 0.001) were observed in patients undergoing simultaneous resection group. The overall survival rate in the simultaneous resection group did not statistically differ with that in the staged resection group at 1 year (P = 0.13), 3 years (P = 0.26), 5 years (P = 0.38), as well as the 1, 3 and 5 years disease‐free survival rates (respectively, P = 0.55; P = 0.16; P = 0.12). No significant difference was noted between the two groups in terms of mortality (P = 0.16), intraoperative blood loss (P = 0.06) and recurrence (P = 0.47). Conclusion: Simultaneous resection is safe and efficient in the treatment of patients with SCLM while avoiding a second laparotomy. In selected patients, simultaneous resection might be considered as the preferred approach. However, the findings have to be carefully interpreted due to the lower level of evidence and the existence of heterogeneity.
