天麻素联合异丙嗪治疗颈性眩晕的临床观察

目的：探讨天麻素注射液联合异丙嗪治疗颈性眩晕的临床疗效。方法将63例颈性眩晕患者随机分为两组,两组基础治疗相同,对照组31例患者采用天麻素注射液进行治疗,观察组32例患者采用天麻素注射液联合异丙嗪进行治疗,比较两组患者的临床疗效和临床症状消失时间。结果治疗后,观察组总有效率为96.87％,明显高于对照组的87.10％（P＜0.05）;观察组临床症状如眩晕、耳蜗症状、自主神经症状、前庭功能受损等消失时间均明显早于对照组（P＜0.05）。结论天麻素注射液联合异丙嗪治疗颈性眩晕疗效显著,有利于患者早日康复。     

疏血通注射液对原发性高血压患者RAAS活性的影响

目的：观察疏血通注射液对原发性高血压患者肾素血管紧张素醛固酮系统（RAAS）活性的影响。方法将入选的原发性高血压患者随机分为治疗组和对照组,观察两组治疗前后血压、血浆肾素（PRA）、血管紧张素Ⅱ（AngⅡ）、醛固酮（ALD）水平及血脂、血流液变学指标的变化。结果治疗后两组患者血浆 AngⅡ、ALD均较治疗前有所降低,治疗组降低更为明显（P＜0．05）,两组患者血浆肾素水平较治疗前升高,但差异无统计学意义（P＞0.05）。治疗组治疗后血压、血脂、血液流变学指标明显改善,与对照组相比差异有统计学意义（P＜0.05或P＜0.01）。结论疏血通注射液对原发性高血压患者 RAAS 活性有明显改善,可降低血浆AngⅡ、ALD的含量,改善血液流变学特性,有效降低血压。     

超声引导下胎儿心肌壁注射KCl在KCl减胎术中的应用效果

目的 探讨超声引导下胎儿心肌壁注射氯化钾（KCl）在中孕期双绒毛膜双羊膜囊双胎妊娠KCl减胎术中的手术效果。方法 回顾性分析2017年9月至2020年1月安徽医科大学第一附属医院收治的因中孕期双绒毛膜双羊膜囊双胎妊娠伴有双胎之一异常行KCl减胎术的27例孕妇临床资料。根据术中KCl注射部位不同将研究对象分为心腔内注射组（超声引导下胎儿心腔内注射KCl）13例及心肌壁注射组（超声引导下胎儿心肌壁注射KCl）14例。比较两组手术时间、KCl用量和围产儿结局的差异。结果 心腔内注射组手术时间为（33.69±2.46）min,长于心肌壁注射组的（19.86±1.51）min,差异有统计学意义（P<0.05）;心腔内注射组KCl用量为（6.00±0.71）mL,多于心肌壁注射组的（2.79±0.54）mL,差异有统计学意义（P<0.05）;分娩28天后电话随访,两组孕妇的分娩孕周及新生儿体质量比较,差异均无统计学意义（P>0.05）。结论 在中孕期KCl减胎术中,心肌壁注射KCl较传统的心腔内注射KCl手术耗时更少,KCl用量更少,且不影响保留胎儿的分娩孕周及新生儿出生体质量。     

Anal intraepithelial neoplasia and squamous cell carcinoma in HIV‐infected adults

Anal cancer is one of the most common non‐AIDS‐defining malignancies in the era of combination antiretroviral therapy. Its precursor lesion, anal intraepithelial neoplasia (AIN), is highly prevalent in HIV‐infected populations. More than 90% of anal squamous cell cancers are attributable to human papillomavirus (HPV). While the biology of HPV‐related intraepithelial neoplasia is consistent across lower anogenital sites, the natural history of AIN is not well established and cannot be assumed to be identical to that of cervical intraepithelial neoplasia. Screening strategies to prevent anal cancer should be developed based on robust natural history data in HIV‐infected and uninfected populations. Likewise, treatments need to be tested in randomized clinical trials, and reserved for those at significant risk of progression to cancer. This review covers the epidemiology, pathogenesis and immunology of HPV infection, AIN and anal cancer, and summarizes the current diagnosis, screening and treatment strategies in HIV‐infected adults.     

Comparison of Biocompatibility of Calcium Silicate-Based Sealers and Epoxy Resin-Based Sealer on Human Periodontal Ligament Stem Cells

The aim of this study was to evaluate the biocompatibility of calcium silicate-based sealers (CeraSeal and EndoSeal TCS) and epoxy resin-based sealer (AH-Plus) in terms of cell viability, inflammatory response, expression of mesenchymal phenotype, osteogenic potential, cell attachment, and morphology, of human periodontal ligament stem cells (hPDLSCs). hPDLSCs were acquired from the premolars (n = 4) of four subjects, whose ages extended from 16 to 24 years of age. Flow cytometry analysis showed stemness of hPDLSCs was maintained in all materials. In cell viability test, AH-Plus showed the lowest cell viability, and CeraSeal showed significantly higher cell viability than others. In ELISA test, AH-Plus showed higher expression of IL-6 and IL-8 than calcium silicate-based sealers. In an osteogenic potential test, AH-Plus showed a lower expression level than other material; however, EndoSeal TCS showed a better expression level than others. All experiments were repeated at least three times per cell line. Scanning electronic microscopy studies showed low degree of cell proliferation on AH-Plus, and high degree of cell proliferation on calcium silicate-based sealers. In this study, calcium silicate-based sealers appear to be more biocompatible and less cytotoxic than epoxy-resin based sealers.
