It is of great significance to analyze the configuration of programs funded by the National Natural Science Foundation of China using funding data in the field of preventive medicine from 2007 to 2021. The analysis mainly focused on the funding status of the program, funding amount, funded institutions and personnel. A total of 5 349 programs in the discipline of preventive medicine were funded over the last 15 years. The funding amount in this discipline accounted for a relatively low proportion in the total funding amount of the Department of Medical Sciences and this proportion also showed a decreasing trend. Non-infectious disease epidemiology, human nutrition, and health toxicology were the top three subdisciplines of all funded programs in preventive medicine. The proportion of programs led by young scholars was gradually rising over the years, and young scholars were playing an increasingly influential role in scientific research. The funding status among each subdiscipline and institution also varied. The results of this study reflected the thriving of preventive medicine. Meanwhile, some problems and dilemmas were also revealed in its current development. Hopefully, this study could provide valuable information for institutions and preventive medicine researchers to apply for National Natural Science Foundation, and promote the long-term development of preventive medicine in the future.分析国家自然科学基金预防医学领域各类型项目的资助情况具有重要意义。本研究汇总2007—2021年国家自然科学基金预防医学领域各类型项目的资助数据，主要针对各类型项目立项数、资助金额、受资助依托单位情况以及受资助人员情况等进行系统分析。15年间预防医学学科共计资助各类型项目5 349项，资助金额占医学科学部资助总金额比例较低，且有占比下降的趋势。非传染病流行病学、人类营养和卫生毒理是获得资助项目数排前3位的分支学科。青年科研人员近年来主持的项目占比逐渐增加，在科学研究中发挥的作用越来越大。各分支学科、各申报单位的情况也有较大差别。以上结果反映出预防医学学科目前的蓬勃发展态势，同时也暴露出当前预防医学学科基础研究中存在的问题，可为各研究单位、预防医学科技工作者未来申报国家自然科学基金项目提供参考，促进预防医学学科的长远发展。.

以原发性醛固酮增多症（PA）为代表的肾上腺疾病是内分泌高血压的主要病因，10%~20%的高血压患者合并PA，PA还是导致难治性高血压、心力衰竭、心肌梗死及卒中等的重要原因。PA的诊断依赖于血生化检测、肾上腺影像学及必要时肾上腺静脉取血。药物干预或外科手术是PA的主要治疗方法，但常会出现药物不能耐受及不适合手术的问题。肾上腺消融术是一种安全、有效、不良反应较小的干预措施，也是对现有PA治疗的重要补充。该文对肾上腺消融术治疗PA相关高血压的临床应用现况、技术关键及应用前景进行了评述。.

It is written to discuss the effect and syndromes of novel YL-1 hollow needle aspiration drainage system to treat chronic subdural hematoma. Collecting clinical data about 697 patients with chronic subdural hematoma in neurosurgery of People' Hospital in North Jiangsu from January 2004 to December 2014, including clinical manifestation, imaging data, operation time, postoperative complications and prognostic factors and so on. 593 patients got cured, 53 patients with recurrence, 19 patients with acute subdural hematoma, 13 patients with poor drainage, 9 case of patients with acute epidural hematoma, puncture failure in 6 cases, 3 cases of pulmonary infection, one got intracranial hemorrhage (brain stem and basal ganglia hemorrhage). The total time of the operation is 15-28 min, the mean time is 18 ± 3.6 min, the average retention time of novel YL-1 hollow needle aspiration drainage system was 2.6 ± 1.3 days, the average use of urokinase was 30,000 ± 2.10,000 units. It takes a short time for novel YL-1 hollow needle aspiration drainage system to treat chronic subdural hematoma without any syndromes like brain tissue injury, tension pneumocrania, intracranial infection and so on. The clinical cure rate is 85.08 %, recurrence rate is 7.6 %. Using novel YL-1 hollow needle aspiration drainage system to treat chronic subdural hematoma is such a minimally invasive surgical technology which has a higher curative rate, small damage, is also easy to operate with security and less severe complications.

To explore the role of HOTAIR in the pathogenesis of adrenocortical carcinoma (ACC) and its underlying mechanism.Differentially expressed lncRNA (HOTAIR) in ACC was screened out from the GEO database. The survival analysis and ROC curve were performed according to HOTAIR expressions in ACC patients. The correlation between HOTAIR expression and clinical information of ACC patients was analyzed by chi-square test. The univariate and multivariate COX regression analysis was carried out to analyze the relationship between HOTAIR expression, disease-free survival (DFS) and overall survival (OS) of ACC patients. We then detected HOTAIR expression in 77 ACC tissues and 30 normal tissues by qRT-PCR (quantitative Real-time polymerase chain reaction). ACC cell lines were further screened out for the following in vitro experiments. After altering HOTAIR expression in ACC cells by plasmid transfection, proliferation and cell cycle were detected by Cell Counting Kit-8 (CCK-8) and colony formation assay, respectively. Finally, Western blot was utilized to detect expressions of cell cycle-related genes in ACC cells.HOTAIR was overexpressed in ACC tissues than that of normal tissues. HOTAIR expression was remarkably increased in ACC with T3 and T4 stage than that of T1 and T2 stage. Moreover, HOTAIR expression was remarkably increased in ACC with stage III and IV than that of stage I and II. HOTAIR was an independent prognostic factor for DFS and OS of ACC patients. For in vitro experiments, inhibited proliferation and arrested cell cycle were observed in H295R cells transfected with si-HOTAIR. Opposite results were obtained after SW-13 cells were transfected with HOTAIR overexpression plasmid. Furthermore, expressions of cell cycle-related genes, including Cyclin D1, p-Rb and p-GSK3β were remarkably decreased after HOTAIR knockdown.We demonstrated for the first time that HOTAIR is overexpressed in ACC and is a prognostic risk factor in ACC patients. HOTAIR participates in the development and progression of ACC via shortening cell cycle and promoting proliferation of ACC cells.

We analyzed the data of application and funding projects of the National Natural Science Foundation of China (NSFC) during 2010-2016 in the field of burns and plastic surgery and summarized the NSFC funding pattern, the research hotspots, and weaknesses in this field. The NSFC has funded 460 projects in the field of burns and plastic surgery, with total funding of RMB 227.96 million. The scientific issues involved in the funding projects include orthotherapy against malformations, wound repair, basic research of burns, skin grafting, scars prevention, and regeneration of hair follicle and sweat glands. The research techniques involved in the funding projects are diversified. NSFC plays an important role in the scientific research and talents training in the field of burns and plastic surgery.
