Then we established a COPD-associated osteoporosis rat model by passive 24-week cigarette exposure. We assessed the efficacy of MBSYQ by lung histopathology assessment and distal femur/the first lumbar vertebra (L1) microstructural assay. In addition, we performed tibial RNA sequencing, which was validated by RT-PCR and Western blot.Results: Screening revealed that the 350 active compounds of MBSYQ anchored 228 therapeutic targets for COPD-related osteoporosis; KEGG pathway enrichment analysis showed that the key targets mainly regulated MAPK and PI3K/AKT signaling pathways. In vivo studies showed that MBSYQ treatment alleviated pathological alterations in lung tissue, and reversed the bone loss and microstructure damage in the femur/L1 of model rats. The RNA seq indicated that MBSYQ could upregulate genes associated with anti-oxidative stress and aerobic respiration. The GSEA analysis displayed that MAPK and PI3K/AKT pathways were inhibited by CS exposure and activated by MBSYQ.Conclusion: MBSYQ is effective in the prevention and treatment of COPD-related osteoporosis, partially achieved by improving oxygen metabolism and activating MAPK and PI3K/AKT pathways.Keywords: COPD, osteoporosis, modified Bu-Shen-Yi-Qi formulae, network pharmacology, transcriptomic

No full textIntroduction: Qing-Re-Xiao-Zheng-Yi-Qi Formula is an effective prescription in diabetic kidney disease treatment, we have confirmed the efficacy of Qing-Re-Xiao-Zheng therapy in diabetic kidney disease through clinical trials. In this study, we investigated the mechanisms of Qing-Re-Xiao-Zheng-Yi-Qi Formula in the treatment of diabetic kidney disease.Methods: We used Vanquish UHPLCTM to analyze the chemical profiling of Qing-Re-Xiao-Zheng-Yi-Qi Formula freeze-dried powder. We constructed diabetic kidney disease rat models induced by unilateral nephrectomy and high-dose streptozocin injection. We examined blood urea nitrogen, serum creatinine, serum glucose, total cholesterol, triglyceride, serum total protein, albumin, alanine aminotransferase, aspartate aminotransferase and 24 h urinary total protein in diabetic kidney disease rats. The renal pathological changes were observed by HE, Masson, PAS stanning and transmission electron microscopy. The levels of fibrosis-related proteins and mitophagy-related proteins were detected by western blot analysis. We also conducted an immunofluorescence co-localization analysis on podocytes to further investigate the effect of Qing-Re-Xiao-Zheng-Yi-Qi Formula treatment on mitophagy.Results: A total of 27 constituents in Qing-Re-Xiao-Zheng-Yi-Qi Formula were tentatively identified. We found PINK1/Parkin-mediated mitophagy was inhibited in diabetic kidney disease. Qing-Re-Xiao-Zheng-Yi-Qi Formula treatment could raise body weight and reduce renal index, reduce proteinuria, improve glycolipid metabolic disorders, ameliorate renal fibrosis, and reduce the expression of Col Ⅳ and TGF-β1 in diabetic kidney disease rats. Qing-Re-Xiao-Zheng-Yi-Qi Formula treatment could also increase the expression of nephrin, activate mitophagy and protect podocytes in diabetic kidney disease rats and high glucose cultured podocytes.Conclusion: PINK1/Parkin-mediated mitophagy was inhibited in diabetic kidney disease, and Qing-Re-Xiao-Zheng-Yi-Qi Formula treatment could not only ameliorate pathological damage, but also promote mitophagy to protect podocytes in diabetic kidney disease.</p

Antiinflammatory Effects of Bu-Zhong-Yi-Qi-Tang in Patients with Perennial Allergic Rhinitis
No full textBu-zhong-yi-qi-tang, an ancient formula of Chinese medicine usually used in the treatment of allergic diseases, was evaluated in the treatment of patients with perennial allergic rhinitis. In this study, 60 patients allergic to house dust mite allergen confirmed by skin test and MAST test were recruited and randomized. An experimental group of 36 patients was treated with Bu-zhong-yi-qi-tang, whereas a control group of 24 patients was treated with a non- effective formula Ping-wei-san for 3 months. The nasal symptomatic scores and the responses of polymorphonuclear neutrophils (PMN) to IL-4-stimulation were measured after treatment. The nasal symptomatic scores in the experimental group were significantly improved (3.78 +/- 0.09 before treatment vs. 0.57 +/- 0.06 after treatment ). In contrast, no change was found in symptomatic scores in the control group (3.17 +/- 0.12 before treatment vs. 2.79 +/- 0.14 after treatment). Moreover, total serum IgE and the IL-4- stimulated production of PGE(2) and LTC4 by PMN was significantly suppressed in the experimental group after treatment compared to the control group. The COX-2 mRNA expression in IL-4-stimulated PMN was also significantly suppressed after Bu-zhong-yi -qi-tang treatment. These results suggest that Bu-zhong-yi-qi-tang but not Ping-wei- san was beneficial to the patients with perennial allergic rhinitis via suppressed nasal inflammation by an antiinflammatory effect.

The Chinese Herb Yi-Qi-Huo-Xue Protects Cardiomyocyte Function in Diabetic Cardiomyopathy
No full textAims. To study the effect of the Chinese herb Yi-qi-huo-xue on cardiomyopathy in diabetic rats. Methods. Rats were fed a high fat and high glucose diet and injected with 50 ml/kg streptozotocin (STZ) to induce diabetic cardiomyopathy (DCM), followed by treatment with Yi-qi-huo-xue for 4 weeks. We measured the rats’ heart weight index, observed the myocardial morphology using hematoxylin eosin (HE) staining, and determined the content of collagen types I and III in the myocardium using enzyme-linked immunosorbent assay (ELISA). We determined Bcl-2, Bax, and P53 protein expression by Western blot analysis and the cardiomyocyte apoptosis rate via a flow cytometry assay. Results. Compared with the rats in the control group, the diabetic rats gained weight and had increased blood sugar levels, an enhanced heart weight index, and increased myocardial pathophysiological damage. There was a decrease in their Bcl-2 expression, and their Bax and P53 expression increased. The Bcl-2/Bax ratio was enhanced, and there was an increase in the content of collagen types I and III in the myocardium. After treatment with Yi-qi-huo-xue, all levels listed above returned to normal. Conclusion. The Chinese herb Yi-qi-huo-xue degraded the myocardial interstitial collagen types I and III to protect the myocardium of the diabetic rats, thus delaying the role of myocardial fibrosis. Yi-qi-huo-xue could play an important role in protecting the myocardium of DCM rats by enhancing the expression of the Bcl-2 protein, inhibiting the expression of the Bax and P53 proteins, increasing the ratio of Bcl-2/Bax, and inhibiting the apoptosis of cardiomyocytes.</jats:p

Protective role of Bu-Zhong-Yi-Qi decoction on aristolochic acid-intoxicated zebrafish
No full textPurpose: To investigate the potential nephroprotective effects of a traditional Chinese medical prescription, Bu-Zhong-Yi-Qi Decoction (BZYQD) in an aristolochic acid (AA)-intoxicated zebrafish model.
Methods: A green fluorescent zebrafish line Tg (wt1b:EGFP) was used, and different exposure protocols were applied. Once a suitable protective concentration of BZYQD was found, antibody staining and real-time PCR methods were applied and the pro-inflammatory gene expressions were determined.
Results: The results showed that low dose (10 ppm) of BZYQD attenuates the AA-induced malformed kidney phenotype. This finding was further substantiated by an examination of the integrity of pronephric tubes in the treated embryos. Pre-treatment with BZYQD suppressed the elevated expressions of pro- inflammatory genes, including tumor necrosis factor-α and myeloperoxidase, induced by AA exposure (1.6 ~ 2.3-fold). This indicates that the nephroprotective effect of BZYQD may be mediated by suppression of pro-inflammatory gene expression. On the other hand, a high dose (500 ppm) of BZYQD caused nephrotoxic effect.
Conclusion: An efficient model to identify AA-protective compounds using zebrafish embryos has been successfully established. Using this strategy, it has been found that BZYQD is nephroprotective in zebrafish embryos, and might have the potential to be applied in humans.補正完畢NG
