穿刺技术的改进和创新是穴位埋线疗法的第三次飞跃

穴位埋线是长效针灸,是在传统针具和针法基础上建立和发展起来的,是针灸技术的发展和延伸,穴位埋线的核心技术是穿刺技术,穴位埋线的三大要素中,针具、埋藏物、穿刺技巧之间是互相影响、互相促进的。针具的改进成功实现了穴位埋线疗法的第一次飞跃,埋藏物的改进成功实现了穴位埋线疗法的第二次飞跃,穿刺技术的改进和创新是穴位埋线疗法的第三次飞跃。     

数据挖掘法探讨周珉教授治疗原发性肝癌用药规律及经验总结

[目的]数据挖掘法分析周珉教授治疗原发性肝癌的中医用药规律,探讨相关病机并进行经验总结。[方法]收集2016年2月—2018年5月周珉教授门诊期间治疗原发性肝癌的方剂,运用"中医传承辅助系统(V2.50)"进行数据挖掘,并结合周珉教授临床经验,进行原发性肝癌病机探讨及用药规律分析。[结果]共收集治疗原发性肝癌方剂176首,涉及中药235种,列出方剂中的高频药物及组合规律。[结论]总结原发性肝癌以"湿热痰毒、气阴两伤"为基础病机,"清热化湿、健脾养阴"治则贯穿原发性肝癌治疗始末,同时,根据疾病不同发展阶段及治疗措施,权衡"扶正"与"祛邪"的主次分配,斟酌应用"攻毒散结""行气化瘀"等治法,以达到改善患者生活质量、延缓疾病进展的目的。     

生物信息学在肝细胞癌风险预测中的应用

生物信息学是一门交叉科学,通过综合运用数学、计算机科学和生物学的各种工具,来阐明和理解大量生物数据所包含的生物学意义。随着基因组学测序技术的不断发展,产生大量的生物学数据资源,从大数据中挖掘所蕴藏的生物学意义,已成为了当前亟待解决的主要任务之一。本文主要归纳总结基于特征基因的肝癌风险预测模型,为肝癌的早期检测、预后和治疗方案的优化提供新观点。     

Myeloid-derived suppressor cell (MDSC) key genes analysis in rat anti-CD28-induced immune tolerance kidney transplantation

BackgroundIn the field of transplantation, inducing immune tolerance in recipients is of great importance. Blocking co-stimulatory molecule using anti-CD28 antibody could induce tolerance in a rat kidney transplantation model. Myeloid-derived suppressor cells (MDSCs) reveals strong immune suppressive abilities in kidney transplantation. Here we analyzed key genes of MDSCs leading to transplant tolerance in this model.MethodsMicroarray data of rat gene expression profiles under accession number {"type":"entrez-geo","attrs":{"text":"GSE28545","term_id":"28545"}}GSE28545 in the Gene Expression Omnibus (GEO) database were analyzed. Running the LIMMA package in R language, the differentially expressed genes (DEGs) were found. Enrichment analysis of the DEGs was conducted in the Database for Annotation, Visualization and Integrated Discovery (DAVID) database to explore gene ontology (GO) annotation and their Kyoto Encyclopedia of Genes and Genomes (KEGG) pathways. Their protein-protein interactions (PPIs) were provided by STRING database and was visualized in Cytoscape. Hub genes were carried out by CytoHubba.ResultsThree hundred and thirty-eight DEGs were exported, including 27 upregulated and 311 downregulated genes. The functions and KEGG pathways of the DEGs were assessed and the PPI network was constructed based on the string interactions of the DEGs. The network was visualized in Cytoscape; the entire PPI network consisted of 192 nodes and 469 edges. Zap70, Cdc42, Stat1, Stat4, Ccl5 and Cxcr3 were among the hub genes.ConclusionsThese key genes, corresponding proteins and their functions may provide valuable background for both basic and clinical research and could be the direction of future studies in immune tolerance, especially those examining immunocyte-induced tolerance.     

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。
