中医药治疗慢性前列腺炎研究概况

综述近年中医药治疗慢性前列腺炎的临床研究,认为本病病因病机之核心在于脾肾亏虚为本,湿热、痰浊、瘀毒为标,病久则伤及脾肾,由实转虚。中医内治法主要以辨证论治、辨病论治或单方验方为主,外治法以中药洗浴、中药灌肠、肛门给药、针灸为主。中医药治疗本病优势明显。应继续完善对中医药作用机制的认识,制订统一的辨证论治及疗效评价标准,针对效果显著的名方开展研究。     

监测数据统计分析模型在生态学研究中的应用

近年来，环境监测、疾病监测等各种监测网络不断健全，监测系统成为开展生态学研究的重要数据来源。监测数据类型包括了横断面数据、时间序列数据和面板数据，涉及暴露、结局和混杂3个维度。针对该数据的信息属性和结构特点，相关统计学方法逐渐发展完善，出现了一些新的方法、模型。基于数据的时空属性，本文对监测数据在生态学研究中常用模型的原理、适用条件及优劣进行了综述。     

乙酰紫草素通过PI3K/Akt信号通路诱导前列腺癌PC-3细胞凋亡的研究

目的：研究乙酰紫草素（ASK）对人前列腺癌PC-3细胞的诱导凋亡作用及相关的分子机制。方法：利用CCK-8实验检测ASK对体外培养PC-3细胞的杀伤作用；利用流式细胞术实验检测ASK处理后PC-3细胞凋亡情况；利用Western blotting检测凋亡蛋白和AKT信号通路蛋白的表达。结果：CCK-8实验证明ASK能够以时间和浓度依赖性抑制前列腺癌PC-3细胞的增殖；流式细胞术实验证明ASK能够诱导人前列腺癌PC-3细胞线粒体依赖性凋亡；Western blotting证明ASK能够有效抑制前列腺癌PC-3细胞中的AKT信号通路。结论：ASK能够有效抑制人前列腺癌PC-3细胞增殖，并能够有效诱导PC-3细胞发生线粒体依赖性凋亡，其机制可能是通过调控PI3K/Akt信号通路来实现，说明ASK具有一定的抗前列腺癌的潜力。     

大数据在中医领域中的癌症预防方面研究

随着现代医疗体系不断完善,癌症治愈率与生存率明显提高,但癌症治疗占据大量医疗资源,治疗过程严重损伤患者的机体,并且治疗费用昂贵。癌症治疗重在"早预防、早发现、早治疗"。本文积极推进中医癌症预防措施,以中医预防大数据平台为手段,实现与地方其他部门的深度融合,构建地区中医预防癌症大数据体系,推动中医资源预防癌症的实效性,努力发挥中医治疗领域大数据作用,为降低居民恶性癌症发病率奠定坚实的基础。     

National level data analysis of facial lacerations in Korea using the National Health Insurance Service (NHIS) database

No national epidemiological investigations have been conducted recently regarding facial lacerations. The study was performed using the data of 3,634,229 people during the 5-year period from 2014 to 2018 archived by the National Health Information Database (NHID) of the Health Insurance Review and Assessment Service. Preschool and children under 10 years old accounted for about one-third of patients. Facial lacerations were concentrated in the “T-shaped” area, which comprised forehead, nose, lips, and the perioral area. The male to female ratio for all study subjects was 2.16:1. Age and gender are significantly related with each other (P < .001). Mean hospital stays decreased, and numbers of outpatient department visits per patient were highest for hospitals and lowest for health agencies. Over the study period, hospital costs per patient in tertiary and general hospitals increased gradually. Preschool and school-aged children are vulnerable to trauma. Male patients outnumbered female patients by a factor of more than 2. The “T-shaped’” area around forehead is vulnerable to injury. Total cost of medical care benefits per patient in tertiary hospitals was about 7 times on average than in health agencies. Regarding functional, behavioral, and aesthetic outcomes, more attention should be paid to epidemiologic data and hospital costs for facial lacerations.     

Extracapsular extension in oral cavity cancers—predictive factors and impact on recurrence pattern and survival

Extracapsular extension (ECE) has long been considered a poor prognostic factor in oral cavity cancer, the presence of which warrants intensification of adjuvant therapy. This study was done to analyze the survival of patients with ECE who received adjuvant chemoradiation. Patients with pathologically confirmed squamous cell carcinoma of the oral cavity, with a minimum of 2 years of follow-up, who were treated at a tertiary cancer centre in New Delhi, India during the years 2009–2017, were included. On multivariate analysis, ECE was significantly associated with depth of invasion >10 mm and tumour deposit size >5 mm. Among the node-positive group, patients without ECE had a 5-year disease-free survival (DFS) and 5-year overall survival (OS) advantage over ECE-positive patients of 7.8% (63.8% vs. 56.0%) and 16.5% (87.2% vs. 70.7%), respectively. For patients with ECE, the hazard ratio for DFS and OS was 1.3 (95% confidence interval 0.97–1.75, P = 0.078) and 2.30 (95% confidence interval 1.35–3.92, P = 0.002), respectively. ECE remains one of the strongest predictors of recurrence and survival in oral cancer patients, and despite aggressive adjuvant therapy, distant recurrence is still significantly high.
