宫腔粘连的危害及影响因素

宫腔粘连指因宫腔操作以及感染等因素影响,造成子宫内膜基底层受损,内膜修复过程中形成的宫腔内和(或)宫颈处粘连、闭塞等。患者可出现月经量少、痛经、不孕及反复妊娠丢失等临床症状,孕期有流产、早产、胎盘植入等风险。本文就发生宫腔粘连的影响因素,该疾病对于患者生理、心理和妊娠的影响,以及相关治疗效果的影响因素三方面加以综述。旨在引起同行对宫腔粘连的重视,加强宫腔粘连的预防。     

Role of surgical treatments in high-grade or advanced gastroenteropancreatic neuroendocrine neoplasms

Over the last 40 years, the incidence and prevalence of gastroenteropancreatic neuroendocrine neoplasms (GEP-NENs) have continued to increase. Compared to other epithelial neoplasms in the same organ, GEP-NENs exhibit indolent biological behavior, resulting in more chances to undergo surgery. However, the role of surgery in high-grade or advanced GEP-NENs is still controversial. Surgery is associated with survival improvement of well-differentiated high-grade GEP-NENs, whereas poorly differentiated GEP-NENs that may benefit from resection require careful selection based on Ki67 and other tissue biomarkers. Additionally, surgery also plays an important role in locally advanced and metastatic disease. For locally advanced GEP-NENs, isolated major vascular involvement is no longer an absolute contraindication. In the setting of metastatic GEP-NENs, radical intended surgery is recommended for patients with low-grade and resectable metastases. For unresectable metastatic disease, a variety of surgical approaches, including cytoreduction of liver metastasis, liver transplantation, and surgery after neoadjuvant treatment, show survival benefits. Primary tumor resection in GEP-NENs with unresectable metastatic disease is associated with symptom control, prolonged survival, and improved sensitivity toward systemic therapies. Although there is no established neoadjuvant or adjuvant strategy, increasing attention has been given to this emerging research area. Some studies have reported that neoadjuvant therapy effectively reduces tumor burden, improves the effectiveness of subsequent surgery, and decreases surgical complications.

总结1例重型弥漫性轴索损伤伴肺挫裂伤患者的肺康复护理经验。护理要点包括：组建多学科肺康复管理团队,实施个性化呼吸支持与降阶梯序贯氧疗护理,精准廓清呼吸道,开展一体化的早期肺功能康复锻炼。经过多学科团队合作,患者入院后第12天撤离呼吸机,第17天拔除气管插管,第20天下床活动,第37天顺利出院,随访6个月,患者恢复良好。     

淫羊藿（苷）对男性生殖系统的作用和机制

淫羊藿是一种常用的中药材,淫羊藿苷是从淫羊藿中提取的一种黄酮类化合物,也是淫羊藿中最主要的活性物质。研究发现,淫羊藿苷具有促进成骨细胞的生成和活化、调节免疫、抗衰老和抗炎等多种功能。临床上淫羊藿（苷）用于治疗生殖系统、骨关节系统、呼吸系统、神经系统、心血管系统和免疫系统等多种疾病。淫羊藿（苷）对男性生殖系统的作用及机制主要包括具有雄性激素样作用,促进睾内睾酮的合成和分泌。淫羊藿（苷）通过改善精子发生的微环境、增强睾丸抗氧化作用促进精子生成,增加精子密度,改善精子活力,减缓生殖衰退。此外,淫羊藿（苷）可促进阴茎勃起,治疗勃起功能障碍及早泄。     

幽门螺杆菌感染相关因素的研究进展

幽门螺杆菌（HP）是革兰阴性微需氧的螺旋样杆菌，主要通过口-口途径在人-人之间感染传播。HP的发现加深了人类对慢性感染、炎症和癌症之间关系的认识。其特定的螺旋形体型、鞭毛及动力、尿素酶和黏附素活性，以及细胞毒素基因A（cagA）、空泡细胞毒素基因A（vacA）等是影响HP感染研究较多的相关致病因素。HP感染在胃癌的发生、发展中可能具有重要作用，但尚未确切证实HP感染是导致胃癌的主因。文章概述了HP感染相关致病因素的研究进展。     

免疫介导坏死性肌病发病机制及诊治分析

目的 探讨免疫介导坏死性肌病的发病机制与临床诊治思路。方法 选取我院肾内科2016年3月收治的1例经肌活检证实为免疫介导坏死性肌病的女性肾病综合征患者，给予糖皮质激素治疗，同时积极控制其肾病综合征，并对其住院诊治过程及门诊随访结果进行分析。结果 糖皮质激素治疗后，肌病迅速得到缓解。随访22个月，肾病在泼尼松联合免疫抑制剂治疗半年，小剂量激素维持半年后得到临床缓解，停药后肾病稳定，随访期间肌病未再复发。结论 免疫介导坏死性肌病为免疫介导的肌病，骨骼肌活检是确诊的主要手段，该病对糖皮质激素治疗的反应良好。但在治疗过程中应重视可能引起免疫紊乱的共病治疗。
