目的运用文献计量学的方法分析中、英文数据库中糖尿病足的研究现状,探究其当前热点研究和今后研究方向。方法分别采用Web of Science(WOS)和中国知网(CNKI)数据库进行中、英文文献的检索,检索日期自建库至2023年3月20日,纳入糖尿病足已发表的相关文献,采用Citespace 5.7.R2软件对纳入文献的国家、机构、作者及关键词等进行分析,绘制相应的可视化图谱。结果分别纳入6295篇和7255篇中、英文文献。结果显示,糖尿病足研究的首篇文献发表于1980年,为中文文献,是关于糖尿病足的治疗和预防的研究。中、英文文献的总发文量呈持续增长趋势,发文量最多的国家是美国,发文最多的国外机构是华盛顿大学;国内发文最多的机构是上海中医药大学附属曙光医院。国外核心作者发文量多于国内核心作者,国内外均尚未形成核心作者合作网络,合作均仅限于研究团队成员之间。关键词聚类方面,英文文献的结果显示目前的研究热点为伤口修复、伤口敷料的应用、抗菌治疗及糖尿病足健康教育,未发现糖尿病足的细胞或分子机制的聚类;中文文献的研究热点包括糖尿病足溃疡、创面愈合、影响因素,尚未形成糖尿病足相关指南的聚类。结论糖尿病足的中、英文研究相差不大,未来应关注糖尿病足的预防和开展相关循证研究、加强研究团队之间的合作,推动糖尿病足研究领域的发展。

Introduction: Hemorrhoidal disease is a common pathology and its surgical treatment is based, among other things, on pedicular resection after failure of medical and instrumental treatment. The aim of this study is to analyze the epidemiological, clinical, therapeutic and evolving aspects of hemorrhoidal disease at the stage of surgical treatment at the University Hospital Center of Brazzaville. Patients and Methods: We conducted a retrospective and descriptive study carried out from January 2020 to december 2021, a 24 months period, in the digestive surgery department of the University Hospital Center of Brazzaville. It concerned patients who underwent a surgical procedure for hemorrhoidal disease. Results: 21 cases were collected, representing a hospital frequency of 2.3%, with a sex ratio of 4.3 in favor of men. The average age of patients was 42.2 ± 11.9 years. The symptoms were mainly proctalgia, mass sensation and rectal bleeding. We recorded five cases (19.1%) of hemorrhoidal thrombosis and 16 cases (80.9%) of hemorrhoidal prolapse including 12 cases requiring manual integration (Goligher grade III) and four irreducible permanent cases (Goligher grade IV). The Grade III prolapse was associated with a polyp in one patient and with posterior anal fissure in another patient. Out of the 21 patients, 14 underwent a tripedicular hemorrhoidectomy according to Milligan and Morgan. Two patients underwent mono- and bipedicular hemorrhoidectomy with resection of associated lesions and five patients underwent emergency thrombectomy. The outcome was favorable for all our patients. The average length of hospital stay was 1.5 ± 2.1 days. Conclusion: In the event of failure of medical and instrumental treatment, the hemorrhoidal cure according to Milligan and Morgan is the surgical treatment of reference for hemorrhoidal disease at the University Hospital Center of Brazzaville.

利用害虫对不同颜色的趋性进行害虫防治,如利用黄板对实蝇的监测和防治已有很长的历史,然而尚未见把颜色量化进行实蝇对颜色偏嗜性研究的报道。为探明对瓜实蝇Bactrocera cucurbitae最具吸引力的颜色及其虚拟波长,本试验应用danBruton的虚拟波长与Rgb值的函数关系,把Rgb值转换为虚拟波长;选择Rgb值[(0,213,255),(0,255,146),(54,255,0),(129,255,0),(195,255,0),(255,255,0),(255,190,0)和(255,119,0)]的颜色进行打印,这些颜色对应的虚拟波长分别是480,500,520,540,560,580,560和600nm;在八面体内进行瓜实蝇对8种颜色的偏嗜性试验。结果表明:波长在520～560nm之间对应的颜色对瓜实蝇的吸引率高于其他虚拟波长对应的颜色,而540nm(黄绿色,Rgb值为129,255,0)对应的颜色纸对瓜实蝇的吸引率最大。此外田间颜色偏嗜性试验也证实了黄绿色对瓜实蝇有最强的引诱作用。结果说明,黄绿色(虚拟波长540nm)是吸引瓜实蝇的关键颜色,黄绿色粘虫板可作为监测与防治瓜实蝇的一种有效方法。

In deep space exploration,it is necessary to improve the accuracy of frequency measurement to meet the requirements of precise orbit determination and various scientific studies.A phase detector is one of the key modules that restricts the tracking performance of phase-locked loop(PLL).Based on the phase relationship between adjacent signals in the time domain,a novel phase detector is presented to replace the arctangent phase *** new PLL,which is a closed loop signal correlation algorithm,shows good performance in tracking signals with high precision and the tracking accuracy of frequency of1 second integration is close to Cramer-Rao lower bound(CRLB)when setting proper *** data processing results further illustrate the excellent performance of the novel PLL.
