采用水热法制备了BiOCl超薄纳米片,并将CdS纳米晶体沉积于BiOCl表面制备CdS/BiOCl复合光催化剂。XRD测试结果证明CdS的沉积不会改变BiOCl的晶体结构。XPS测试结果表明CdS/BiOCl复合材料已被成功合成。SEM及HRTEM测试结果证明,CdS纳米晶体均匀沉积在BiOCl的表面。荧光光谱分析数据表明CdS/BiOCl复合材料的电子-空穴分离效果得到有效提高,均优于纯BiOCl材料,且随着Cd(Ac)_(2)·2H_(2)O添加量的增加,复合材料的荧光光谱强度呈现先减弱后增强的现象。根据紫外可见漫反射光谱及XPS价带谱测试结果,计算出复合材料的价带与导带电位。以盐酸四环素作为模拟污染物评价光催化剂的活性,结果表明,CdS/BiOCl复合材料光催化活性更高,仅需经过5 min的可见光照射后,优选的CdS/BiOCl(CB-8)复合材料对盐酸四环素的去除率可达70.6%,为纯BiOCl的16.2倍。最终,根据XPS价带谱和活性物种捕获实验结果推测了CdS/BiOCl复合光催化剂的光催化反应机理。

Background: Cesarean section (CS) has increased steadily over the last decade, with an estimated one-third of women delivering by cesarean section worldwide. Objective: Our study aimed to investigate the demographic and associated factors influencing vaginal birth after one cesarean (VBAC-1) success focusing on variables like pre-pregnancy BMI, diabetes, hypertension, education, and smoking. Study Design and Methods: In this retrospective study, we analyzed 285 cases (81 unsuccessful VBAC-1, 204 successful VBAC-1) from San Juan City Hospital (Puerto Rico) between January 1, 2019, and December 31, 2020. We used odds ratios and model selection comparison to assess the impact of variables on successful VBAC-1, using a significance threshold of 95% CI. Model selection assessed binomial model combinations using a generalized linear approach to identify key risk factors. Results: Unsuccessful VBAC-1 (a repeat cesarean), was associated with diabetes (OR: 0.376, p = 0.086), hypertension (OR: 0.23, p = 0.006), and university-educated women (OR: 1.372, p = 0.711). High school-educated women had an OR of 3.966 (p = 0.105), while overweight women were 0.481 times more likely to have unsuccessful VBAC-1 (p = 0.041). Significant associations were not found with obesity (OR: 0.574, p = 0.122), underweight/normal (OR: 1.01, p = 0.810), or smoking (OR: 1.227, p = 0.990). Conclusion: Results revealed women with higher education levels, hypertension, or diabetes are less likely to have a successful VBAC-1. Understanding the complex interactions affecting these outcomes is aimed at establishing guidelines for healthcare professionals to conduct systematic risk/benefit assessments. This study lays a foundation for evidence-based practices and policies, offering initial insights into VBAC-1 success factors in Puerto Rico.

目的比较眼肌型重症肌无力(OMG)患者接受或不接受免疫抑制治疗的全身转化风险。方法回顾了2015年1月1日至2019年5月1日在空军军医大学唐都医院注册登记的OMG患者的资料,按照是否接受免疫抑制治疗将患者分为治疗组和对照组,使用多因素Cox比例风险回归模型分析比较了发病后2年内两组患者的疾病转化风险。通过敏感性分析,评估了免疫抑制治疗时程以及不同免疫治疗方案下的转化风险;使用分层分析,评价了不同亚组因子水平下主要结果的一致性。结果共收集702例以眼肌症状起病的重症肌无力(MG)患者的信息,367例(52.3%)患者被纳入治疗组,平均发病年龄为(50.54±15.1)岁,其中159例(43.3%)为女性。335例(47.7%)患者被纳入对照组,平均年龄(49.1±14.6)岁,159例(47.5%)为女性。治疗组中28例(7.7%),对照组中106例(31.6%)患者在观察期内转化为全身型重症肌无力(GMG)。经多变量校正的Cox模型分析后发现,与对照组相比,接受免疫抑制治疗的患者全身转化风险明显降低(HR=0.24;95%CI:0.15~0.37;P<0.001)。敏感性分析发现,免疫抑制持续时间越长,转化风险越低(HR=0.88;95%CI:0.85~0.91;P<0.001)。分层分析显示,不同亚组中患者接受免疫抑制治疗均可降低转化风险。结论早期接受免疫抑制治疗可以显著降低OMG患者向全身型转化的风险。
