Hypertension is a risk factor for adverse outcomes in patients with coronavirus disease 2019: a cohort study

Abstract

Background

Comorbidities are commonly seen in patients with coronavirus disease 2019 (COVID-19), but the clinical implication is not yet well-delineated. We aim to characterize the prevalence and clinical implications of comorbidities in patients with COVID-19.

Shape changes produced in detergent extracted bovine retinal pigment epithelium when exposed to ATP. A comparison with fibroblasts and smooth muscle cells

The response of single detergent treated bovine retinal pigment epithelial cells in culture to ATP was measured with an image analyser. The most pronounced contraction was produced by 1.0 mM ATP with most change taking place in the first 10 min. At 1 h the area had decreased by about 33%, perimeter 22% and maximum length 25%. By way of comparison rabbit skin fibroblasts had a decreased area of approximately 40%, perimeter 25% and maximum length 22%. Bovine aortic smooth muscle cells on the other hand decreased in area by 55%, perimeter 40% and maximum length 36%. It is hoped that this assay may be used to evaluate drugs which could counteract contractile events in proliferative vitreoretinopathy.     

喉罩全麻在颈动脉狭窄造影及介入治疗术中的应用

目的：观察喉罩全麻下行颈动脉狭窄的造影诊断及介入治疗术的临床效果。方法：择期DSA下颈动脉狭窄患者23例，年龄42-78岁，无明显肺部疾患及喉罩禁忌症患者，异丙酚（Pmpofol）泵入静脉全麻下插入喉罩完成手术，观察其不同时段的BP（MAP）、SpO2、HR、ECG（ST-Ⅱ）。结果：各时段的BP（MAP）、Sp02、HR、ECG（ST-Ⅱ）比较无显著性差异。结论：喉罩全麻在行颈动脉狭窄的造影诊断及介入治疗术的临床效果是肯定的。喉罩全麻颈动脉狭窄造影介入治疗     

电针治疗周围性面瘫疗效观察

目的:寻找能提高治疗周围性面瘫疗效的适宜的电针波型.方法:将147例周围性面瘫患者随机分为治疗组和对照组,治疗组进行穴位分组,电针波型先用连续波后用疏密波治疗;对照组穴位不分组,并单纯采用连续波治疗.结果:两组的总有效率和痊愈所用时间经统计学处理,差异有非常显著性意义(P＜0.01).结论:在电针治疗周围性面瘫中,将疏密波和连续波配合使用,效果显著优于单纯使用连续波者.     

大脑中动脉支架内血栓形成1例报告

支架内血栓形成是支架置入术后的一种常见并发症。术后血管内皮损伤、胶原组织暴露和作为异物的支架均为引发血栓形成的可能机制。不能及时识别处理则成为再狭窄的重要原因。我们报告1例发生在大脑中动脉（middle cerebral artery，MCA）支架内的血栓形成，探讨其识别处理过程和可能的机制。     

沙培林增强人腹腔巨噬细胞抗癌免疫功能的研究

目的:探讨腹腔内注射沙培林增强人腹腔抗癌免疫功能的机制。方法:72例早中期胃肠道肿瘤患者术前48h和24h腹腔内分别注射生理盐水和5KE的沙培林,术中采集腹腔内巨噬细胞,计数并测定乳酸脱氢酶(LDH)和酸性磷酸酶(ACP)的活性,巨噬细胞吞噬活力,一氧化氮(NO)的分泌以及对人胃癌MKN1细胞的细胞毒性进行分析。同时采集大网膜,对大网膜乳斑的数量和面积进行观察。结果:沙培林显著增加腹腔巨噬细胞(PMΦ)的数量和NO的分泌,增强LDH和ACP的活性,吞噬活力,以及抗癌细胞毒性,也显著增加了大网膜乳斑的数量和面积。结论:腹腔内注射沙培林可显著增加人大网膜乳斑的数量和面积,并因此增加PMΦ的数量,增强PMΦ的活性。因而增强了腹腔巨噬细胞的免疫功能。
