从形气神谈溃疡性结肠炎的中西医认识

溃疡性结肠炎(Ulcerative colitis,UC)是一种病情反复、迁延难愈的炎症肠病,已被世界卫生组织列为现代难治病之一[1]。本病病因及发病机制尚不明确,西药治疗效果欠佳。近年来中医药的介入,临床取得显著疗效。西医学认为疾病是机体在一定致病因素的作用下自稳调节紊乱,经过机体内损伤和抗损伤反应的相互斗争,表现出的一系列功能。     

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.     

The effectiveness of specialized nursing interventions for patients with Parkinson disease: A randomized controlled study protocol

Background:The purpose of this experiment is to evaluate the impact of the care of Parkinson disease nurse specialist on improving motor symptoms and life quality for patients with Parkinson disease (PD).Method:This is a randomized controlled research, and it will be conducted from April 2021 to October 2021 at Sichuan Provincial People''s Hospital. The experiment was granted through the Research Ethics Committee of Sichuan Provincial People''s Hospital (004510293). All the patients suffer from PD, age 18 years or older, both female and male, regardless of the duration or severity of this disease are eligible. The exclusion criteria contains: lack sufficient knowledge to complete questionnaires, serious physical comorbidities or refuse to take part in the program. In our experiment, the major result measures are motor symptoms and life quality. For the measurement of life quality, we will utilize Parkinson disease Questionnaire-39, the most extensively utilized the scale of life quality in PD. The evaluation of motor symptoms severity is carried out with the revision of Unified Parkinson Disease Rating Scale sponsored by Movement Disorder Society.Results:Table 1 indicates clinical outcomes at different time points.Conclusion:The Parkinson''s disease nurse specialist care may promote the life quality in the PD patients.Trial registration number:researchregistry 6284.     

基于龋风险评估的龋病治疗计划

随着对龋病病因及发病机制的深入认识,龋病的治疗不应局限于对现有龋损的修复治疗,而应以龋病风险评估和龋损活跃性评估为基础,以患者为中心,制定个性化的治疗方案,恢复口腔微生态平衡,进而控制龋病进展和恢复患牙的结构与功能。     

GLP-1类似物在糖尿病肾病患者中的疗效分析

目的观察胰高血糖素样肽-1(glucagon-like peptide-1,GLP-1)类似物对2型糖尿病早期肾病患者的肾脏保护作用。方法2017年11月—2019年12月间选取使用GLP-1类似物并参与随访的2型糖尿病早期肾病患者30例,收集患者治疗6个月前后的体重,体质指数(body mass index,BMI),腰围,臀围,血糖,生化指标等,计算胰岛β细胞功能相关指标,进行对比分析。结果治疗后腰围、2 hPG、HbA1c、HOMA-IR、TC、TG、ALB、MA/Cr、UA较治疗前降低,HOMA-β较治疗前升高,差异有统计学意义(P<0.05)。Pearson相关性分析示:HbA1c与MA/Cr呈负相关性(r=-0.421,P<0.05);HOMA-β、TG、TC、UA与MA/Cr呈正相关性(r=0.777,P<0.05;r=0.757,P<0.05;r=0.470,P<0.05;r=0.443,P<0.05)。HbA1c与ALB呈负相关性(r=-0.433,P<0.05);HOMA-β、TG、TC、UA与ALB呈正相关性(r=0.723,P<0.05;r=0.756,P<0.05;r=0.493,P<0.05;r=0.374,P<0.05)。结论GLP-1类似物对2型糖尿病早期肾病患者有较好的降糖、调脂、改善胰岛功能、保护肾脏的作用,而且降血糖、降血脂、改善胰岛功能可能有益于肾脏保护。     

基因组拷贝数变异测序与染色体核型分析在胎儿遗传学诊断中的比较

目的比较基因组拷贝数变异测序(CNV-seq)技术和染色体核型分析和在产前胎儿遗传学诊断中的应用价值。方法收集来我院有产前诊断指征进行羊水穿刺的259例孕妇,取材后,送检染色体核型分析和CNV-seq,比较两种方法在产前诊断中的优缺点。结果259例标本中,共诊断异常染色体核型及微缺失微重复23例,总阳性诊断率8.88%(23/259),CNV-seq结果显示,共有22例染色体拷贝数异常(12例三体+9例微缺失微重复+1例三倍体),检出率为8.49%;染色体核型分析结果显示为:17例染色体异常(12例三体+3例结构异常+1例嵌合型+1例三倍体),检出率为6.56%。此外还检出染色体多态7例。结论CNV-seq与染色体核型分析对于染色体非整倍体的检测效力一致,CNV-seq能检测染色体微缺失微重复,染色体核型分析则能诊断出三体具体核型,在怀疑性染色体异常时,建议行两者联合检测。
