Effects of acupuncture and pelvic floor muscle training on bladder dysfunction after spinal cord injury: A meta-analysis.

OBJECTIVE: We aimed to systematically review and quantify the association between acupuncture and pelvic floor muscle exercise and bladder dysfunction rehabilitation in individuals with spinal nerve injury. METHODS: A meta-analysis was conducted using an evidence-based nursing analysis method based on clinical evidence. China National Knowledge Infrastructure, PubMed, VIP database, Wan Fang database, Cochrane Library, and other databases were searched by computer from January 1, 2000 to January 1, 2021. The literature was searched for clinical randomized controlled trials on acupuncture stimulation, pelvic floor muscle function training, and bladder function recovery training after spinal cord nerve injury. Two reviewers independently used The Cochrane Collaboration recommended randomized controlled trial risk of bias assessment tool to evaluate the quality of the literature. Then, the meta-analysis was performed using RevMan 5.3 software. RESULTS: A total of 20 studies were included, with a total sample size of 1468 cases, including 734 patients in the control group and 734 patients in the experimental group. The results of our meta-analysis showed that acupuncture treatment [OR = 3.98, 95% CI (2.77, 5.72), Z = 7.49, P < .001] and pelvic floor muscle treatment [OR = 7.63, 95% CI (4.47, 13.04), Z = 7.45, P < .001] was statistically significant. CONCLUSION: Acupuncture and pelvic floor muscle exercise are effective intervention and treatment methods, which have obvious effects on rehabilitation treatment of bladder dysfunction after spinal nerve injury.

Correlation between inflammatory cytokines and liver cancer stem cell markers in DEN-induced liver cancer rats.

OBJECTIVE: To study the association of inflammatory factors and hepatocarcinoma stem cells of induced liver cancer rats. MATERIALS AND METHODS: 30 SD male healthy rats were selected. 10 rats were given water as normal control group. 10 rats only were implemented laparotomy as sham operation group. The remaining 10 rats were the liver cancer model group and treated with diethylnitrosamine (DEN) to induce liver cancer. Real-time quantitative PCR was used to detect the related inflammatory factors in HCC tissues, including interleukin-6 (IL-6), monocyte chemoattractant protein-1 (MCP-1), transforming growth factor-ß1 (TGF-ß), human interleukin-1α (IL-1α), human interleukin 1ß (IL-1ß) and levels of hepatocarcinoma stem cells indicators CD90, CD133, Alpha-fetoprotein (AFP). Correlation analysis was used to analyze the correlation between inflammatory factors and hepatocarcinoma stem cells markers CD90 and CD133. RESULTS: The expression levels of IL-6, MCP-1 and TGF-ß of HCC tissues in liver cancer model group were significantly higher than those in the control group and the sham operation group. The expression levels of CD90 and CD133 of tissues in the liver cancer model group were significantly higher than those in the control group and the sham operation group. The differences were statistically significant (p<0.001). By inhibiting related inflammatory factors, the growth, migration and invasion of liver cancer cells were significantly inhibited, and apoptosis was promoted. Correlation analysis results showed that the expression changes of IL-6, MCP-1 and TGF-ß were significantly positively correlated with CD90 up-regulation (p<0.05), while the expression changes of IL-6, MCP-1 and TGF-ß were significantly positively correlated with CD133 up-regulation (p<0.05). CONCLUSIONS: The inflammatory factors IL-6, MCP-1 and TGF-ß are closely related to hepatocarcinoma stem cells, which play an important role in promoting the occurrence and deterioration of liver cancer.
