[Metabolomics of interventional effects of Coptidis Rhizoma and its processed products on oral ulcer due to excess heat in rats].

Ultra-high-performance liquid chromatography coupled with quadrupole time-of-flight mass spectrometry(UPLC-Q/TOF-MS) was employed to examine the impact of Coptidis Rhizoma(CR) and its processed products on the metabolism in the rat model of oral ulcer due to excess heat and to compare the effectiveness of CR and its three products. Male SD rats were randomly allocated to the sham-operation(Sham), model(M, oral ulcer due to excess heat), CR, wine/Zingiberis Rhizoma Recens/Euodiae Fructus processed CR(wCR/zCR/eCR), and Huanglian Shangqing Tablets(HST) groups. Except the Sham group, the other groups were administrated with Codonopsis Radix-Astragali Radix decoction by gavage for two consecutive weeks. The anal temperature and water consumption of rats were monitored throughout the modeling period of excess heat. Following the completion of the modeling, oral ulcer was modeled with acetic acid. Hematoxylin-eosin(HE) staining was employed to observe the mucosal pathological changes in oral ulcer. A colorimetric assay was employed to determine the serum level of glutathione peroxidase(GSH-Px). Enzyme-linked immunosorbent assay(ELISA) was conducted to determine the levels of tumor necrosis factor-alpha(TNF-α), interleukin-6(IL-6), interleukin-1ß(IL-1ß), superoxide dismutase(SOD), and malondialdehyde(MDA) in the serum. The non-targeted metabolomics analysis based on UPLC-Q/TOF-MS was conducted on the serum samples. Metabolic profiles were then built, and the potential biomarkers were screened by principal component analysis(PCA) and orthogonal partial least squares discriminant analysis(OPLS-DA). The Mev software was used to establish a heat map and conduct cluster analysis on the quantitative results of the markers. The online databases including MBRole, KEGG, and MetaboAnalyst were used for pathway enrichment analysis and metabolic network building. The experimental results showed that the modeling led to pathological damage to the oral mucosa, elevated serum levels of TNF-α, IL-6, IL-1ß, and MDA, and lowered levels of SOD and GSH-Px in rats. The drug administration recovered all the indices to varying extents, and wCR exhibited the best performance. Non-targeted metabolomics identified 48 differential metabolites including 27 metabolites in the positive ion mode and 21 metabolites in the negative ion mode. Five enriched pathways were common, including glycerophospholipid metabolism, linoleic acid metabolism, and tyrosine metabolism. Conclusively, CR and its three processed products could alleviate the inflammation and oxidative stress injury in rats suffering from oral ulcers due to excess heat by regulating lipid and amino acid metabolism. Notably, wCR demonstrated the most significant therapeutic effect.

Coptis chinensis-Induced Changes in Metabolomics and Gut Microbiota in Rats.

Rhizoma coptidis (CR) is traditionally used for treating gastrointestinal diseases. Wine-processed CR (wCR), zingiber-processed CR (zCR), and evodia-processed CR (eCR) are its major processed products. However, the related study of their specific mechanisms is very limited, and they need to be further clarified. The aim of this study is to compare the intervening mechanism of wCR/zCR/eCR on rats via faecal metabolomics and 16S rDNA gene sequencing analysis. First, faecal samples were collected from the control and CR/wCR/zCR/eCR groups. Then, a metabolomics analysis was performed using UHPLC-Q/TOF-MS to obtain the metabolic profile and significantly altered metabolites. The 16S rDNA gene sequencing analysis was carried out to analyze the composition of gut microbiota and screen out the significantly altered microbiota at the genus level. Finally, a pathway enrichment analysis of the significantly altered metabolites via the KEGG database and a functional prediction of relevant gut microbes based on PICRUSt2 software were performed in combination. Together with the correlation analysis between metabolites and gut microbiota, the potential intervening mechanism of wCR/zCR/eCR was explored. The results suggested that wCR played a good role in maintaining immune homeostasis, promoting glycolysis, and reducing cholesterol; zCR had a better effect on protecting the integrity of the intestinal mucus barrier, preventing gastric ulcers, and reducing body cholesterol; eCR was good at protecting the integrity of the intestinal mucus barrier and promoting glycolysis. This study scientifically elucidated the intervening mechanism of wCR/zCR/eCR from the perspective of faecal metabolites and gut microbiota, providing a new insight into the processing mechanism research of Chinese herbs.

[Yijingfang for the treatment of asthenospermia: A randomized controlled clinical trial].

OBJECTIVE: To investigate the clinical therapeutic effects of Yijingfang, a Chinese medicinal liquid, on asthenospermia. METHODS: We randomly divided 450 asthenospermia patients into a treatment group (n = 300) and a control group (n = 150), the former treated with Yijingfang once half a dose, bid, and the latter with Wuziyanzong Pills (9 g, bid) + L-carnitine oral liquid (10 ml, bid), both for 3 months. Before and at 1, 2, and 3 months after medication, we compared the semen volume, sperm concentration, percentages of progressively motile sperm (PMS) and total motile sperm (TMS), and semen liquefaction time between the two groups of patients. RESULTS: No statistically significant difference was observed in the semen parameters between the treatment and control groups before medication (P >0.05). In comparison with the baseline, the treatment group showed significant differences at 1, 2, and 3 months after medication in sperm concentration (ï¼»35.96 ± 8.50ï¼½ vs ï¼»49.66 ± 10.91ï¼½, ï¼»55.21 ± 11.46ï¼½, ï¼»74.90 ± 13.07ï¼½ ×106/ml, P <0.01), PMS (ï¼»19.72 ± 2.06ï¼½ vs ï¼»23.81 ± 2.56ï¼½, ï¼»26.12 ± 2.34ï¼½, and ï¼»32.17 ± 1.62ï¼½ %, P <0.01) and TMS (ï¼»28.86 ± 2.70ï¼½ vs ï¼»34.17 ± 3.43ï¼½, ï¼»36.59 ± 3.36ï¼½, and ï¼»47.08 ± 2.97ï¼½ %, P <0.01), but not in the semen volume (ï¼»3.35 ± 0.99ï¼½ vs ï¼»3.15 ± 1.06ï¼½, ï¼»3.12 ± 0.90ï¼½, and ï¼»3.27 ± 0.78ï¼½ ml, P >0.05) or semen liquefaction time (ï¼»32.31 ± 8.15ï¼½ vs ï¼»31.68 ± 3.14ï¼½, ï¼»30.38 ± 3.44ï¼½, and ï¼»30.86 ± 2.42ï¼½ min, P >0.05); the control group exhibited similar results at the three time points in sperm concentration (ï¼»36.85 ± 6.88ï¼½ vs ï¼»40.53 ± 8.32ï¼½, ï¼»47.51 ± 12.73ï¼½, and ï¼»56.14 ± 11.98ï¼½ ×106/ml, P <0.01), PMS (ï¼»20.26 ± 2.73ï¼½ vs ï¼»25.17 ± 2.64ï¼½, ï¼»27.23 ± 2.25ï¼½, and ï¼»31.89±2.27ï¼½ %, P <0.01), and TMS (ï¼»30.03 ± 2.67ï¼½ vs ï¼»33.89±2.26ï¼½, ï¼»37.38±4.79ï¼½, and ï¼»40.35±3.06ï¼½ %, P <0.01), but not in the semen volume (ï¼»3.03 ± 1.09ï¼½ vs ï¼»3.16±1.78ï¼½, ï¼»3.15±0.96ï¼½, and ï¼»3.12±0.65ï¼½ ml, P >0.05) or semen liquefaction time (ï¼»30.25 ± 5.20ï¼½ vs ï¼»29.36±4.25ï¼½, ï¼»28.21±3.26ï¼½, and ï¼»28.33±3.59ï¼½ min, P >0.05). There were statistically significant differences between the treatment and control groups in the increase rates of sperm concentration and TMS after medication (P <0.01) but not in that of PMS (P >0.05). CONCLUSIONS: Yijingfang is an effective drug for the treatment of asthenospermia, which can regulate the spermatogenesis, increase the percentage of PMS, and improve the total sperm motility of the patients.

[Triple acupuncture at the Qugu acupoint as an adjunctive therapy for type-â ¢ chronic prostatitis: Analysis of short- and long-term clinical effects].

OBJECTIVE: To investigate the short- and long-term effects of triple acupuncture at the Qugu acupoint as an adjunctive therapy on type-Ⅲ chronic prostatitis / chronic pelvic pain syndrome (CP/CPPS). METHODS: We equally randomized 90 CP/CPPS patients into a control and a treatment group, both treated with Levofloxacin Mesylate Tablets (0.5 g, tid) + Terazosin Hydrochloride Capsules (2 mg qd) for 4 weeks, while the latter group by triple acupuncture at the Qugu acupoint as an adjunctive therapy twice a week at the same time. Then, we followed up all the patients for 4 weeks, recorded the cases, time and rate of recurrence, obtained the scores in National Institutes of Health Chronic Prostatitis Symptom Index (NIH-CPSI), quality of life (QoL) and Zung Depression Scale (ZDS), and compared them between the two groups of patients. RESULTS: Compared with the controls, the patients of the treatment group showed significantly decreased NIH-CPSI scores in pain (8.6 ± 2.12 vs 6.2 ± 2.25, P <0.05), micturition (5.8 ± 1.22 vs 3.1 ± 1.10, P <0.05), and QoL (6.0 ± 1.33 vs 3.4 ± 1.71, P <0.05) and ZDS score as well (43.9 ± 4.53 vs 33.6 ± 3.20, P <0.01). The recurrence rate was markedly lower while the recurrence time remarkably longer in the treatment than in the control group (15.56 vs 35.56% and ï¼»20.0 ± 2.72ï¼½ vs ï¼»12.5 ± 3.47ï¼½ d, P <0.05). CONCLUSIONS: As an adjunctive therapy, triple acupuncture at the Qugu acupoint can evidently ameliorate the clinical symptoms, enhance the curative effect of antibacterials, reduce the recurrence rate, and prolong the recurrence time in the treatment of CP/CPPS.
