RESUMO

ETHNOPHARMACOLOGICAL RELEVANCE: Xinyang tablet (XYT) has been used for heart failure (HF) for over twenty years in clinical practice, but the underlying molecular mechanism remains poorly understood. AIMS OF THE STUDY: In the present study, we aimed to explore the protective effects of XYT in HF in vivo and in vitro. MATERIALS AND METHODS: Transverse aortic constriction was performed in vivo to establish a mouse model of cardiac pressure overload. Echocardiography, tissue staining, and real-time quantitative PCR (qPCR) were examined to evaluate the protective effects of XYT on cardiac function and structure. Adenosine 5'-triphosphate production, reactive oxygen species staining, and measurement of malondialdehyde and superoxide dismutase was used to detect mitochondrial damage. Mitochondrial ultrastructure was observed by transmission electron microscope. Immunofluorescence staining, qPCR, and Western blotting were performed to evaluate the effect of XYT on the mitochondrial unfolded protein response and mitophagy, and to identify its potential pharmacological mechanism. In vitro, HL-1 cells and neonatal mouse cardiomyocytes were stimulated with Angiotensin II to establish the cell model. Western blotting, qPCR, immunofluorescence staining, and flow cytometry were utilized to determine the effects of XYT on cardiomyocytes. HL-1 cells overexpressing receptor-interacting serum/three-protein kinase 3 (RIPK3) were generated by transfection of RIPK3-overexpressing lentiviral vectors. Cells were then co-treated with XYT to determine the molecular mechanisms. RESULTS: In the present study, XYT was found to exerta protective effect on cardiac function and structure in the pressure overload mice. And it was also found XYT reduced mitochondrial damage by enhancing mitochondrial unfolded protein response and restoring mitophagy. Further studies showed that XYT achieved its cardioprotective role through regulating the RIPK3/FUN14 domain containing 1 (FUNDC1) signaling. Moreover, the overexpression of RIPK3 successfully reversed the XYT-induced protective effects and significantly attenuated the positive effects on the mitochondrial unfolded protein response and mitophagy. CONCLUSIONS: Our findings indicated that XYT prevented pressure overload-induced HF through regulating the RIPK3/FUNDC1-mediated mitochondrial unfolded protein response and mitophagy. The information gained from this study provides a potential strategy for attenuating mitochondrial damage in the context of pressure overload-induced heart failure using XYT.

RESUMO

OBJECTIVE: To explore the rules of acupoint selection and drug use in treatment of hypertension with acupoint application therapy. METHODS: The articles of the clinical research of hypertension treated with acupoint application therapy were retrieved from Chinese journal full-text database (CNKI), VIP database (VIP) and Wanfang databases from the time of establishment to January 20, 2019. The database was set up with Microsoft Excel 2010. Using the cloud platform of the ancient and modern medicine record, the frequency statistical and clustering analyses were conducted. RESULTS: A total of 117 articles were collected, including 191 prescriptions, 60 aucpoints and 236 kinds of herbal drugs. It was found in the frequency statistical analysis that the top 6 acupoints in use frequency were Yongquan (KI 1), Quchi (LI 11), Taichong (LR 3), Shenque (CV 8), Sanyinjiao (SP 6) and Neiguan (PC 6). According to the correlation analysis, corresponding to these top 6 acupoints, the pairs of acupoints were Sanyinjiao (SP 6) and Yongquan (KI 1), Shenque (CV 8) and Yongquan (KI 1), Neiguan (PC 6) and Yongquan (KI 1), Zusanli (ST 36) and Sanyinjiao (SP 6), Sanyinjiao (SP 6) and Neiguan (PC 6) with Yongquan (KI 1), as well as Yongquan (KI 1) and Neiguan (PC 6) with Sanyinjiao (SP 6). The dominant meridians were the kidney meridian, the conception vessel and the bladder meridian. The special acupoints referred to yuan-source point, luo-connecting point, back-shu point and front-mu point. The top 3 herbal drugs in use frequency included fructus evodiae, semen sinapis and rhizoma chuanxiong. The herbs used were mainly warm and slight cold in nature and neutral in property. The frequencies of the drug use were similar in the application for cold and heat purposes. The common flavors of the herbal medicines were pungent, sweat and bitter and the liver, kidney and spleen meridians were generally involved in meridian tropism. CONCLUSION: In treatment of hypertension with acupoint application therapy, the commonly used single acupoint is Yongquan (KI 1), which is generally combined with Sanyinjiao (SP 6), Shenque (CV 8), Neiguan (PC 6) and Zusanli (ST 36). The correlation is emphasized on the application of special acupoints, meridian points and zangfu organs. The vesicatory herbal drugs are predominant in the drug use. In generally, this therapy embodies the treatment principles as tonifying for the deficiency and reducing for the excess, as well as balancing of cold and heat.

RESUMO

ABSTRACT We present the case of a 28 year old patient with an incomplete tear of the tunica albuginea occurred after having sexual intercourse in the female superior position. The diagnostic assessment was performed first clinically, then with CT, owing to its high resolution, allowed to exactly detect the tear location leading to precise preoperative planning. After adequate diagnosis through imaging and proper planning, the patient was performed a selective minimally invasive surgical approach to repair the lesion. The patient had good erection with no angular deformity or plaque formation after a 3-month follow-up.
