Epidemiological study of intraosseous lesions of the stomatognathic or maxillomandibular complex diagnosed by a Reference Centre in Brazil from 2006–2017

This epidemiological study was designed to find out the incidence and factors associated with the occurrence of intraosseous lesions diagnosed at a Reference Centre in Brazil. We included all patients diagnosed with intraosseous lesions (cyst, tumour, bone-associated lesion, and periapical disease) during the period 2006–2017, and analysed the association between some sociodemographic and clinical variables and the types of lesion. There was a total of 290 intraosseous lesions, the most common being odontogenic cysts. There was a significant association between age and odontogenic tumours (p = 0.001). In relation to the histopathological diagnosis, root cysts were the most common (n = 57), followed by dentigerous cysts (n = 26). The lesions studied were seen most often in women between the second and fourth decades of life, odontogenic cysts being the most common type found. We know of few publications of similar epidemiological work, either in Brazil or in the rest of the world, so we suggest that more such studies are made.

中药药对治疗糖尿病肾病的药理作用及临床应用研究进展

中药药对是中医临证方剂配伍中画龙点睛之所在,目前关于中药治疗糖尿病肾病的相关研究较多,但主要聚焦在疗效观察和处方总结等方面,缺乏对中药作用机制的深入研究和归纳总结。中药药对与方剂相比化学成分少、组方形式单一、作用机制简单、干扰因素较少等。近年来中医在应用药对治疗糖尿病肾病方面积累了丰富的临床实践经验,不少研究者十分注重组方配伍时药对的应用及其作用规律,通过药对配伍实现多方面的优化组合,进一步提高中药复方的治疗效果。为了明确中药药对治疗糖尿病肾病的作用途径及靶点,本文通过系统地查阅和整理国内外相关文献资料,拟对近10年来经临床观察与动物实验证实对糖尿病肾病确有疗效的,以中医临证分型具有"调补脾肾""利水渗湿""活血化瘀"和"收敛固涩"功效的四类药对的组成规律及现代实验研究现状进行整理分析,总结其配伍原则与药物的化学成分、药代动力学变化及药对各中药不同配伍比例时化学成分的变化规律,以期为上述药对进一步的应用、研究及开发提供参考。
