病案首页的准确填写与统计报表的关系

病案首页是医院医疗统计最基本的数据,《中华人民共和国统计法》第二条规定:“统计的基本任务是对国民经济和社会发展情况进行统计调查、统计分析,提供统计资料和统计咨询意见,实行统计监督。”数据不准确为上级卫生行政部门了解和掌握居民的医疗需求,医疗服务情况,编制区域医疗规划与卫生事业发展计划,评价医疗服务的社会效益和经济效益,对领导部门决策、与世界各国的资料交流等都会产生不良影响。所以病案首页的准确填写很重要,要认真、如实、规范才能真正反映实际情况。现就常见不规范或填写不准确的主要情况列出如下:

Comparative study of different transplantation methods of adipose tissue-derived stem cells in the treatment of erectile dysfunction caused by cavernous nerve injury

We aimed to compare intracavernosal injection (ICI), tail vein injection (IV), and periprostatic injection (PPI) of adipose-derived stem cells (ADSCs) for their ability to improve erectile function in cavernous nerve injury-induced erectile dysfunction (CNIED) rats and to explore the possible mechanism. Eighty-four male SD rats were divided into the sham group (n = 6), BCNI group (bilateral CN crush injury, n = 6), PBS-ICI group (n = 6), PBS-IV group (n = 6), PBS-PPI group (n = 6), ADSC-ICI group (n = 18), ADSC-IV group (n = 18) and ADSC-PPI group (n = 18). ADSCs were labelled with 5-ethynyl-2′-deoxyuridine (EdU), and six rats each in the ADSC-ICI group, ADSC-IV group, and ADSC-PPI group were sacrificed 2, 7, and 28 days after injection. EdU-labelled ADSCs were tracked by immunofluorescence staining. The intracavernosal pressure (ICP)/mean arterial pressure (MAP) ratio, neuronal nitric oxide synthase (nNOS)-positive nerve fibres in the dorsal penile nerve and the smooth muscle/collagen ratio in the cavernosum between groups were also evaluated. ADSCs can significantly improve erectile function through ICI or IV. The two are similar in efficacy and superior to PPI. The mechanism may be that after CN injury, ADSCs are recruited to around the MPG and secrete a variety of neurotrophic factors that promote the repair of the CN, thereby improving erectile function.
