Objective:To identify the effects of Xuefu Zhuyu Capsule (XZC) on the surgical treatment of patients with chronic subdural hematoma (CSDH).Methods:Retrospectively collected 96 pairs of patients who undergoing burr-hole craniotomy (BHC) for CSDH from January 2016 to December 2019 in Dalian Municipal Central Hospital. Clinical characteristics and imaging information of each patient were extracted, the follow-up period was six months. Differences in demographics and postoperative outcomes were compared between BHC+XZC group and BHC only group. Univariate analysis and multivariate analysis with Logistic regression model were performed to determine independent associations among the various probable effective factor. The relationship between related factors and effectiveness of CSDH was estimated with odds ratio ( OR) and 95% CI. Results:Effectiveness in 87 cases (90.6%) patients with surgery and received XZC postoperatively was significantly higher than 76 cases (79.2%) patients who underwent surgery alone. Multivariate Logistic regression analysis showed postoperative administration of XZC and preoperative Glasgow coma scale (GCS) score were independent protective factors for CSDH to improve therapeutic effect.Conclusions:This study suggested postoperative administration of XZC for CSDH patients can improve the therapeutic effect, a higher preoperative GCS score is contributed to the postoperative effect.

Objective:To study the expression and clinical significance of collagen type Ⅰ alpha 2 chain (COL1A2) in glioma , and its effect on the migration and invasion of glioma cell lines.Methods:Through in-depth mining of the data related to COL1A2 in the Oncomine database, meta-analysis of its expression in different types of tumors, different grades and different molecular types of glioma, and then through the Chinese glioma genome map project (Chinese Glioma Genome Atlas, CGGA) database to explore the relationship between its expression level and the prognosis of glioma patients. The COL1A2 gene was functionally annotated by gene ontology (GO) and Pathway analysis. The annotation content includes cell components, biological processes, molecular functions and related signal pathways.Results:A total of 426 research results on COL1A2 in different types of tumors were collected in the Oncomine database, 114 of which were statistically different, 103 studies with increased COL1A2 expression, and 11 studies with decreased expression; the analysis shows there were 22 studies on high expression of COL1A2 in tumors, and no studies on low expression. Analysis of different grades of glioma and different molecular types of glioma Compared with the control group, COL1A2 was highly expressed in various types of glioma. Through the analysis of the gene chip data of the CGGA database, it was found that in glioblastoma, low expression levels of COL1A2 were significantly associated with an improved prognosis in patients with glioma ( P<0.05). Next, through GO and Pathway annotations, it was found that COL1A2 was involved in the biological processes of NAD metabolic salvage pathway, cell and cell signal transduction, circadian rhythm regulation and so on. Finally, through the construction of overexpression and knockdown cell lines in glioblastoma cell lines U87 and T98, scratch experiments and transwell cell function experiments confirmed that COL1A2 can significantly promote the migration and invasion of glioblastoma cell lines. Conclusions:Low expression levels of COL1A2 were significantly associated with improved prognosis in patients with glioma. Knockdown and overexpression of COL1A2 on glioblastoma cell lines U87 and T98 manifested that COL1A2 can promote glioblastoma cell lines migration and invasion ability. Based on the above results, COL1A2 may be used as an indicator for judging the prognosis of glioblastoma and as a potential biological target for therapy.
