非引导种植术种植体三维位置精确度分析

目的：分析简单种植病例非引导植入种植体的位置偏差。方法：筛选3名医师治疗的68例简单种植牙患者,共97颗种植体,术后利用CBCT软件测量种植体颈部、尖部、角度偏差。比较3名不同医师、左右后牙与前牙区、游离端与非游离端种植体在颈部、尖部、角度偏差方面的差异。采用SPSS 22.0软件包进行统计学分析。结果：97颗种植体颈部、尖部、角度偏差平均值为（0.76±0.57）mm、（1.41±0.90）mm、（4.76±3.68）°。医师间比较颈部、尖部、角度偏差,差异有统计学意义（P<0.05）。左右后牙组间比较,3项偏差差异无统计学意义（P>0.05）,左侧后牙与前牙相比,3项偏差差异有统计学意义（P<0.05）;右侧后牙与前牙组相比,3项偏差差异无统计学意义（P>0.05）。游离端与非游离端比较,颈部偏差差异有统计学意义(P<0.05),尖部、角度偏差差异无统计学意义(P>0.05)。结论：简单病例非引导种植的总偏差与计算机导板相仿,偏差与医师经验相关,前牙组偏差小于双侧后牙组,非游离端颈部偏差小于游离端。     

内耳局部给药临床与实验研究进展

药物治疗一直是内耳病的首选方法,由于内耳与全身血液循环之间存在血 迷路屏障,药物进入内耳的剂量极为有限。内耳局部给药可以减小用药剂量与药物的不良反应,药物在内耳的作用效力也会提高。关于内耳局部给药的临床应用有鼓膜穿刺/经咽鼓管给药、经圆窗膜缓释/控释给药、内耳开窗给药,实验研究包括缓释药物制剂和控释给药装置的研究。作者对内耳局部给药的临床与实验研究进行综述,为更加微创、有效治疗疾病提供依据。     

Role of p19ink4d in the pathogenesis of hearing loss

This study aimed to investigate the p19 expression in cisplatin-treated rats and the role of p19 in the degeneration of inner ear cells. It also searched for p19 gene alterations in patients with profound sensorineural deafness. P19ink4d is essential for the postmitotic maintenance of hair cells. It is presumed that a mutation in the functional homolog of p19 or a disturbance in its regulated expression can be the underlying cause of hearing loss. Experiments were conducted on male and female Sprague-Dawley rats (aged 6-7 weeks, 280-320 g) with thresholds of auditory brainstem responses <30 dB in the sound pressure level, and signs of middle ear infection were used for the experiment. For clinical evaluation, 400 children (age less than 13 years) from unrelated families with severe or profound sensorineural hearing loss (SNHL) were recruited at the second Xiangya Hospital of Central South University between 2005 and 2013, and genomic DNA for deafness gene analysis was obtained from peripheral blood samples of the patients and their lineal relatives. It was found that the p19 expression increased over time in the inner ear cells after cisplatin administration, but the p19 mRNA and protein levels significantly decreased in rats with manifested hearing loss induced by cisplatin. However, no mutation existed within the coding exons of p19 in the patients with profound sensorineural deafness. To conclude, the results support the concept that p19 may play an important role in the ototoxic effects of cisplatin and is probably involved in the pathogenesis of hearing loss.

柴可群三阶段辨治大肠癌经验

柴可群主任中医师认为,大肠癌是在人体正气不足的基础上,外邪乘虚入侵,复因饮食、情志所伤,使脏腑功能失调,气血津液运行失常,产生气滞、血瘀、痰凝、湿浊、热毒等病理变化,蕴结于肠腑,相互搏结,日久积渐而成;是一种以正气虚损为本,局部实邪结聚为标,本虚标实的病证。正气亏虚、癌毒内蕴是大肠癌的基本病机,同时也是大肠癌复发转移的根本原因。治疗原则为"扶正为本,祛邪有度,全程调神,随证而治"。具体根据根治阶段、随访阶段、姑息治疗阶段中正邪盛衰的主次和疾病发生发展的特点,及时调整用药,并强调在该病临床各期均需要结合中医药的治疗,进行全程管理。
