清热解毒方辅助一次性根治术治疗小儿肛周脓肿临床研究

目的：观察清热解毒方辅助一次性根治术治疗小儿肛周脓肿的疗效及对肉芽组织生长的影响。方法：选取120 例肛周脓肿患儿，按随机数字表法分为对照组和观察组各60 例。对照组行一次性根治术治疗，观察组在对照组基础上术后加用清热解毒方坐浴治疗。比较2 组中医症状评分、渗液评分、视觉模拟评分法（VAS） 评分及肉芽组织生长评分，评价2 组临床疗效及不良反应发生情况。结果：观察组总有效率为91.67%，高于对照组73.33%，差异有统计学意义（P＜0.05）。治疗后，2 组肛门肿痛、夜寐不安、恶寒发热、溲赤便秘、舌红苔黄等中医症状评分较治疗前降低，且观察组各症状评分均低于对照组（P＜0.05）。治疗后，2 组渗液评分、VAS 评分均较治疗前降低，且观察组渗液评分、VAS 评分均低于对照组（P＜0.05）。治疗后，观察组创面愈合时间、腐肉脱落时间、肉芽组织生长评分均少于对照组，创面愈合度高于对照组（P＜0.05）。观察组不良反应发生率为6.67%，低于对照组20.00%，差异有统计学意义（P＜0.05）。结论：清热解毒方辅助一次性根治术治疗小儿肛周脓肿临床疗效显著，可有效改善患儿中医临床症状和肉芽组织生长情况，加快患儿伤口愈合，安全性较好。     

以专培学员为主导的CBL教学对心血管专培学员自身综合能力提升的影响

心血管专科医师规范化培训目标要求高于住院医师培训，完成心血管专培的医生应能在医疗、教学、科研能力上明显提高，达到心血管专科主治医师水平。如何提高心血管专培学员教学能力是专培中的难点。将专培学员随机分为两组,分别采用案例教学法（case-based learning, CBL）和传统教学法进行带教,课程结束后通过测验和调查问卷两种方式对教学效果进行考察。旨在探讨由心血管专培学员主导CBL教学法在实施过程中是否对其自身综合能力有所提升。结果显示，CBL教学法组学生临床理论及病例分析考试分数均高于对照组；心血管专培学员通过主导CBL教学，在教学能力、组织能力和学科协调均有提升；相较传统教学法,CBL教学法的教学效果更佳,有利于心血管专培学员自身综合能力提升。     

Identification of key genes and pathways in discoid lupus skin via bioinformatics analysis

Discoid lupus erythematosus (DLE) is the most common skin manifestation of lupus; however, the molecular mechanisms underlying DLE remain unknown. Therefore, we aimed to identify key differentially expressed genes (DEGs) in discoid lupus skin and investigate their potential pathways.To identify candidate genes involved in the occurrence and development of the disease, we downloaded the microarray datasets {"type":"entrez-geo","attrs":{"text":"GSE52471","term_id":"52471"}}GSE52471 and {"type":"entrez-geo","attrs":{"text":"GSE72535","term_id":"72535"}}GSE72535 from the Gene Expression Database (GEO). DEGs between discoid lupus skin and normal controls were selected using the GEO2R tool and Venn diagram software (http://bioinformatics.psb.ugent.be/webtools/Venn/). The Database for Annotation, Visualization, and Integrated Discovery (DAVID), Enrichr, and Cytoscape ClueGo were used to analyze the Kyoto Encyclopedia of Gene and Genome pathways and gene ontology. Protein-protein interactions (PPIs) of these DEGs were further assessed using the Search Tool for the Retrieval Interacting Genes version 10.0.Seventy three DEGs were co-expressed in both datasets. DEGs were predominantly upregulated in receptor signaling pathways of the immune response. In the PPI network, 69 upregulated genes were selected. Furthermore, 4 genes (CXCL10, ISG15, IFIH1, and IRF7) were found to be significantly upregulated in the RIG-I-like receptor signaling pathway, from analysis of Enrichr and Cytoscape ClueGo.The results of this study may provide new insights into the potential molecular mechanisms of DLE. However, further experimentation is required to confirm these findings.     

Dorsal suspension for Morton’s neuroma: A comparison with neurectomy

BackgroundThe purpose of this study was to investigate and compare the clinical outcomes of dorsal suspension with those of neurectomy for the treatment of Morton’s neuroma.MethodsWe conducted a retrospective study of dorsal suspension and neurectomy group. The dorsal suspension was performed by dorsal transposition of neuroma over the dorsal transverse ligament after neurolysis. The visual analog scale (VAS), the Foot and Ankle Ability Measure (FAAM), postoperative satisfaction, and complications were evaluated.ResultsBoth groups reported significant pain relief, and there were no significant differences between the groups with respect to postoperative pain. The postoperative FAAM outcomes showed no significant between-group differences. Satisfaction analysis showed ‘excellent’ and ‘good’ results in the dorsal suspension and neurectomy groups (95% and 77.7%, respectively). Complications of numbness and paresthesia reported in the dorsal suspension group (5% and 5%, respectively) were significantly fewer than those of neurectomy group (61.1% and 33.3%, respectively) (both, p < .05).ConclusionsWith its favorable results, dorsal suspension can be another operative option for the treatment of Morton’s neuroma.Level of Evidence: Level III, retrospective comparative case series.
