简介：AbstractBackground:Obstetric hemorrhage is a major cause of maternal death during cesarean delivery. The objective of this retrospective observational study was to evaluate the efficacy and safety of intra-operative cell salvage (IOCS) in cesarean section.Methods:We included a total of 361 patients diagnosed with central placenta previa who underwent cesarean section from May 2016 to December 2018. In this study, 196 patients received autologous transfusion using IOCS (IOCS group) and 165 patients accepted allogeneic blood transfusion (ABT group). Propensity score matched analysis was performed to balance differences in the baseline variables between the IOCS group and ABT group. Patients in the IOCS group were matched 1:1 to patients in the ABT group.Results:After propensity score matching, 137 pairs of cases between the two groups were successfully matched and no significant differences in baseline characteristics were found between the IOCS group and ABT group. Patients in the IOCS group were associated with significantly shorter length of hospital stay, compared with ABT group (8.9 ± 4.1 days vs. 10.3 ± 5.2 days, t= -2.506, P = 0.013). The postoperative length of hospital stay was 5.3 ± 1.4 days for patients in the IOCS group and 6.6 ± 3.6 days for those in the ABT group (t = -4.056, P < 0.001). The post-operative hemoglobin level in the IOCS group and ABT group was 101.3 ± 15.4 and 96.3 ± 16.6 g/L, respectively, which were significantly different (t= 2.615, P= 0.009). Allogeneic red blood cell transfusion was significantly lower at 0 unit (range: 0–11.5 units) in the IOCS group when compared with 2 units (range: 1–20 units) in the ABT group (P < 0.001).Conclusions:This retrospective observational study using propensity score matched analysis suggested that IOCS was associated with shorter length of postoperative hospital stay and higher post-operative hemoglobin levels during cesarean delivery.

简介：模型是将设计方案物化为与实物相似的形象直观的一种物体。模型制作既能增强技术设计的视觉感染力，又可帮助设计者通过反复观摩、推敲分析、不断修改完善设计方案的可靠性，进而求得最佳设计效果。模型是对设计理念的具体表达，是设计委托者与设计人员和使用者之间交流的“技术语言”，而这种“技术语言”是三维实体造型，展现了设计“物”的具体形态。

简介：AbstractObjective:To compare and correlate the efficacy of the NOSE score & the VAS score in determining the symptomatic benefit in patients undergoing septoplasty.Materials and methods:Eighty patients with deviated nasal septum undergoing septoplasty were included in the study. NOSE score & VAS score (out of 100) was documented before and after surgery. Results were correlated and compared statistically.Results:In the NOSE score, the most bothersome symptom was trouble breathing through the nose (85.83); followed by Nasal obstruction or blockage (82.50). Wilcoxon test showed significant improvement with NOSE score and VAS score in all patients at 1 month and 3 months. Spearman’s coefficient showed a positive correlation between the two, though the score improvement and patient satisfaction rate was significantly high with NOSE score.Conclusions:NOSE score and the VAS score both provide effective framework for evaluating treatment responses after septoplasty. However, the NOSE score showed higher improvement and better patient satisfaction rate when used to measure of nasal obstruction as compared to the VAS score.

简介：目的:研究损伤严重程度感知(ISP)评分法在测试急性挥鞭样损伤患者中的复测可重复性。方法:在基层保健中心连续对急性阶段患急性挥鞭样损伤患者采用ISP评分。ISP是一种通过数字等级进行评分,其测量范围从0到10,受试者被要求指出他们自认为的受伤严重程度。0代表'无损伤',10代表'严重且永久性损伤'。利用ISP问卷对同一批受试者在招募完成时及7天后进行评分。复测可重复性由一致百分率和在两个时间点进行的Kappa分析进行计算。锚定两端分别标记为'没有损伤'(0)和'严重损伤,可能是永久性损伤'(10)。结果:实验包括94名研究对象(34名男性,60名女性,平均年龄为40.6±10.0岁,范围19-60岁),在刚招募时JSP平均得分为4.9±1.7(评分在2-9之间),一周后ISP平均得分为5.1±2.1(评分在2-9之间)。在ISP的两次重复测量中百分比一致率为86%,Kappa系数为0.79。结论:这项研究表明ISP复测可重复性在预后研究中偏倚风险较低。ISP评分法在急性挥鞭样损伤患者的流行病学研究中具有相当高的可靠性。
