Clinical study of Xuefu Zhuyu Capsule combined with drilling and drainage in the treatment of chronic subdural hematoma / 中国医师进修杂志

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.

Application of "spider-web" mode in discovery and identification of Q-markers from Xuefu Zhuyu capsule.

BACKGROUND: The selection of quality control indicators in a complex system is a key scientific issue for the study of Chinese materia medica (CMM), which is directly related to its safety and efficacy. In order to scientifically understand and control the quality of CMM, quality marker (Q-marker) has been recently raised as a new concept, which provided a novel research idea for the quality control and evaluation of CMM. PURPOSE: By a new and integrated "spider-web" mode, Q-markers of Xuefu Zhuyu capsule (XZC) were comprehensively uncovered, conducing to great improvement of quality control of XZC. METHODS: Mainly established by three dimensions derived from six variables including content, stability and activity, "spider-web" mode was constructed to evaluate Q-marker property of candidate compounds by taking regression area of the tested compounds into account. RESULTS: The candidate compounds with larger regression area were preferentially adopted as Q-markers, which should possess the satisfactorily integrated properties of content, stability and activity. Six compounds, naringin, isoliquiritin, paeoniflorin, protocatechuic acid, neohesperidin and ferulic acid, were identified and preferred as Q-markers of XZC. CONCLUSION: Based on "spider-web" mode, Q-markers from Xuefu Zhuyu capsule were successfully screened, which would substantially perform quality control of XZC and prove the feasibility of "spider-web" mode in solving the selection of quality control indicators from compound formulae.

Effect of Xuefu Zhuyu Capsule () on Angiogenesis in Hindlimb Ischemic Rats.

OBJECTIVE: To investigate the effect and mechanism of Xuefu Zhuyu Capsule (, XZC) on pro-angiogenesis in the hindlimb ischemic model rats. METHODS: A total of 100 Sprague Dawley rats were randomly divided into a model group, a regular-dose XZC group (0.48 g•kg-1•d-1) and a high-dose XZC group (0.96 g•kg-1•d-1) using random number table method. The model of hindlimb ischemic rats were made through femoral artery embolization with Bletilla microsphere agent. XZC were given on the first day after embolization surgery and lasted 5 days. Finally 72 models were obtained with 12 in each group for each time point. The lower ischemic limb was amputated on the third day after embolization surgery. Histopathological characters and the number of blood vessels of granulation tissues were observed at 36 and 48 h after amputation, respectively. The main genes were obtained from microarray analysis and were validated using real-time quantitative polymerase chain reaction. RESULTS: The vascular number of granulation tissues at both 36 and 48 h were characterized by new and fresh vessels. The number of angiogenesis in the high-dose XZC group at 36 and 48 h was greater compared with that in the regular-dose XZC and model groups (P<0.01), and high-dose XZC at 36 h increased more vessels than that at 48 h (P<0.01). Consequently, granulation tissues from the high-dose XZC group at 36 h were chosen for microarray analysis. In all, 2,085 differentially expressed genes (DEGs) were detected and 25 DEGs were determined to be directly related to angiogenesis. Four biological process terms were found including angiogenesis, regulation of angiogenesis, positive regulation of angiogenesis, and positive regulation of vascular endothelial growth factor receptor signaling pathway (P<0.05). Microarray analysis also showed 49 pathways including 11 pathways related to angiogenesis. CONCLUSION: XZC promoted angiogenesis moderately and the mechanism involved multiple DEGs and multiple pathways.

Effect of EphB4/EphrinB2 reverse signal on angiogenesis induced by Xuefu Zhuyu Capsule () containing serum in human microvascular endothelial cell 1.

OBJECTIVE: To evaluate the effect of Xuefu Zhuyu Capsule ()-containing serum (XFZY-CS) on EphB4/ephrinB2 and its reverse signal in human microvascular endothelial cell-1 (HMEC-1). METHODS: XFZY-CS and the blank control serum were collected. HMEC-1 cells were randomly assigned to 6 groups including the concentration 1.25%, 2.5%, and 5% XFZY-CS groups and their blank serum control ones. The angiogenesis effect of XFZY-CS was tested with an in vitro tube formation assay and the best condition of pro-angiogenesis was determined. The effect of XFZY-CS on EphB4/ephrinB2 and the reverse signal were determined by Western blot and real-time quantitative polymerase chain reaction, respectively; we also confifirmed the results through activating and inhibiting the reverse signal by EphB4/fc and pyrophosphatase/ phosphodiesterase2 (PP2). RESULTS: XFZY-CS promoted angiogenesis at the concentration of 2.5% corresponding serum after being cultured for 48 h, while inhibited angiogenesis at the concentration of 5% after culturing for 48 and 72 h. Under the 2.5% serum concentration, XFZY up-regulated the expression of EphB4-mRNA at 12 h (P<0.05), and down-regulates its expression at 24 h (P<0.01). Protein expression of EphB4 was apparently up-regulated at 12 h and down-regulated at 24 h. The phosphorylation of ephrinB2 increased at 9 h (P<0.05). In addition, 2.5% XFZY-CS played a similar role as the reverse signaling activator EphB4/Fc ranging from 0.5 to 5 µg/mL (P>0.05). XFZY-CS also reduced the inhibitive effect of PP2 in limited periods. CONCLUSIONS: EphB4/ephrinB2 was the upstream signal in the process of angiogenesis and its reverse signaling was responsible for XFZY's effect on promoting angiogenesis.
