Effect of Banxia Xiexin Decoction on intestinal flora of mice with ulcerative colitis induced by dextran sodium sulfate / 中国中药杂志

The aim of this paper was to investigate the effect of Banxia Xiexin Decoction(BXD) on inflammatory factors and intestinal flora in a dextran sulfate sodium induced ulcerative colitis(DSS-UC) mouse model, and to explore the mechanism of BXD in treating ulcerative colitis from the perspective of flora disorder. Forty C57 BL/6 J mice were randomly divided into control group, model group and BXD group. A 2.5% DSS-induced ulcerative colitis model was established. On the 8 th day, normal saline, normal saline, and BXD were given daily for 14 days. After 14 days, HE staining was used to observe histopathological changes of the colon. Serum inflammatory factor content was detected by ELISA, and the change of intestinal flora in mice feces was detected by 16 S rRNA sequencing technology. Compared with control group, the colonic tissue of mice in model group was damaged seriously, and the contents of IL-6 and TNF-α in serum were significantly increased(P<0.05). Compared with model group, mice in BXD group had less colonic damage, and the contents of IL-6, TNF-α in serum were decreased significantly(P<0.05). After creation, the richness of Patescibacteria was increased significantly at the phylum level(P<0.05). At the same time, the richness of Faecalibaculum(P<0.01), norank_f_Muribaculaceae(P<0.01) were decreased significantly at the genus level, while the richness of Turicibacter(P<0.01), Romboutsia(P<0.01), Clostridium_sensu_stricto_1(P<0.01) were increased significantly. After the intervention with BXD, the content of Patescibacteria was significantly reduced at the phylum level(P<0.05), and the contents of Lactobacillus(P<0.01), Clostri-dium_sensu_stricto_1(P<0.01), Enterorhabdus(P<0.01), Candidatus_Saccharimonas(P<0.05), Eubacterium_fissicatena_group(P<0.05) were decreased significantly at the genus level, while the contents of Dubosiella, Bacteroides and Allobaculum were increased significantly. Therefore, BXD could significantly improve the symptoms of DSS-UC mice. It not only could reduce the contents of IL-6 and TNF-α, but also could reduce the richness of Patescibacteria at the phylum level, and those of Clostridium_sensu_stricto_1, Candidatus_Saccharimonas, Eubacterium_fissicatena_group at the genus level. Inaddition, BXD could increase the richness of Bacteroides and Bifidobacterium. It suggested that BXD could play a role in the treatment of ulcerative colitis partially through reducing inflammatory factors and regulating the structure of the gut microbiota.

Stored autologous blood transfusion does not increase recurrence of prostate cancer after radical prostatectomy: A preliminary study / 中华男科学杂志

Objective@#To analyze the association of stored autologous blood transfusion (SABT) with tumor recurrence in PCa patients after radical prostatectomy and explore the application of SABT in this surgical procedure.@*METHODS@#Forty-five PCa patients underwent radical prostatectomy in our hospital in recent five years, of whom, 20 received SABT (group A) and the other 25 allogeneic blood transfusion (group B) intraoperatively. After surgery, we followed up the patients regularly for 3－66 months by examination of the levels of total PSA (tPSA) and free PSA (fPSA), digital rectal examination (DRE), and MRI to observe the biochemical recurrence of the tumor. We compared the data obtained between the two groups of patients.@*RESULTS@#In group A, 8 cases were in stages T1a－T1b and 12 in stages T2a－T2c, and in group B, 14 cases were in stages T1a－T1b and 11 in stages T2a－T2c. The volume of transfused blood was 800 ml in group A and 400－1 200 ml in group B. No statistically significant differences were observed between the two groups in the operation time, intraoperative blood loss or postoperative Gleason scores (P > 0.05), nor in the tPSA level or the results of DRE and MRI at 12, 24, 36, 48 and over 48 months (P > 0.05).@*CONCLUSIONS@#SABT is safe for PCa patients undergoing radical prostatectomy and does not increase the tumor recurrence rate after surgery.
