Cardiac toxicity of anthracycline greatly limit its clinical use,to explore the rule of anthracycline cardiotoxicity and prevention and control strategies of Chinese and western medicine,this paper through the literature search mechanism and drugs is summarized,the mechanism can be divided into oxidative stress,inflammatory reaction,myocardial cell autophagy and DNA damage four categories,the prevention and treatment of western medicine to dc prosamine,ACEI,ARB is given priority to,Chinese medicine can be divided into single medicine,by prescription and proprietary Chinese medicine.On this basis,the combination drug is discussed to prevent cardiotoxicity,and the theoretical basis and research status of the combined application of western medicine,traditional Chinese medicine and Chinese and western medicine are introduced.The results show that it has good feasibility and safety,and can provide reference for the clinical treatment strategy of anthracycline chemotherapy drugs.

Objective:Jue tone is a kind of sound,using 3-mi as the main tone,and is melodious,profound,makes people feel comfortable and pleasant.This study aimed to explore the probable mechanism of Jue tone to reduce blood pressure (BP) in hypertensive rats with a liver-fire hyperactivity pattern by observing changes in BP as well as physiochemical indexes in plasma.Methods:Sixteen male spontaneous hypertensive rats (SHR) with a liver-fire hyperactivity pattern were randomly divided into a control group and a Jue tone group.The rats in the Jue tone group were treated with Jue tone (55-65 dB,played by the five elements of music rhythm instrument,a kind of physio-therapy regimen music played by Shen Wu) once a day for 4 weeks.The BP levels in each group were measured twice a week,on Monday and Friday.The levels of angiotensin Ⅱ (Ang-Ⅱ),thromboxane B2(TXB2),endothelin-1 (ET-1),calcitonin gene-related peptide (cGRP),norepinephrine (NE),cortisol(CORT),and 5-hydroxytryptamine (5-HT).in plasma were detected by enzyme-linked immunosorbent assay after 4 weeks of intervention.Results:BP and the levels of TXB2 and ET-1 in the plasma of the treatment group were significantly lower than those of the control group,while the level of cGRP was significantly higher.Conclusion:Jue tone can reduce the BP of hypertensive rats with a liver-fire hyperactivity pattern.The mechanism may correlate with a reduction in TXB2 and ET-1 and an increase in cGRP with the reduction of reactive oxygen species (ROS).

The occurrence of benign prostate hyperplasia(BPH)was related to disrupted sex steroid hormones,and metformin(Met)had a clinical response to sex steroid hormone-related gynaecological disease.How-ever,whether Met exerts an antiproliferative effect on BPH via sex steroid hormones remains unclear.Here,our clinical study showed that along with prostatic epithelial cell(PEC)proliferation,sex steroid hormones were dysregulated in the serum and prostate of BPH patients.As the major contributor to dysregulated sex steroid hormones,elevated dihydrotestosterone(DHT)had a significant positive rela-tionship with the clinical characteristics of BPH patients.Activation of adenosine 5'-monophosphate(AMP)-activated protein kinase(AMPK)by Met restored dysregulated sex steroid hormone homeostasis and exerted antiproliferative effects against DHT-induced proliferation by inhibiting the formation of androgen receptor(AR)-mediated Yes-associated protein(YAP1)-TEA domain transcription factor(TEAD4)heterodimers.Met's anti-proliferative effects were blocked by AMPK inhibitor or YAP1 over-expression in DHT-cultured BPH-1 cells.Our findings indicated that Met would be a promising clinical therapeutic approach for BPH by inhibiting dysregulated steroid hormone-induced PEC proliferation.

Benign prostatic hyperplasia(BPH)is one of the major chronic complications of type 2 diabetes mellitus(T2DM),and sex steroid hormones are common risk factors for the occurrence of T2DM and BPH.The profiles of sex steroid hormones are simultaneously quantified by LC-MS/MS in the clinical serum of patients,including simple BPH patients,newly diagnosed T2DM patients,T2DM complicated with BPH patients and matched healthy individuals.The G protein-coupled estrogen receptor(GPER)inhibitor G15,GPER knockdown lentivirus,the YAP1 inhibitor verteporfin,YAP1 knockdown/overexpression lentivirus,targeted metabolomics analysis,and Co-IP assays are used to investigate the molecular mechanisms of the disrupted sex steroid hormones homeostasis in the pathological process of T2DM complicated with BPH.The homeostasis of sex steroid hormone is disrupted in the serum of patients,accompanying with the proliferated prostatic epithelial cells(PECs).The sex steroid hormone metabolic profiles of T2DM patients complicated with BPH have the greatest degrees of separation from those of healthy individuals.Elevated 17β-estradiol(E2)is the key contributor to the disrupted sex steroid hormone homeostasis,and is significantly positively related to the clinical characteristics of T2DM patients complicated with BPH.Activating GPER by E2 via Hippo-YAP1 signaling exacerbates high glucose(HG)-induced PECs prolifer-ation through the formation of the YAP1-TEAD4 heterodimer.Knockdown or inhibition of GPER-mediated Hippo-YAP1 signaling suppresses PECs proliferation in HG and E2 co-treated BPH-1 cells.The anti-proliferative effects of verteporfin,an inhibitor of YAP1,are blocked by YAP1 overexpression in HG and E2 co-treated BPH-1 cells.Inactivating E2/GPER/Hippo/YAP1 signaling may be effective at delaying the progression of T2DM complicated with BPH by inhibiting PECs proliferation.

Objective To establish the quality representation and correlation analysis method and the content of characteristic ingredients based on spectrum of medicinal system of Juemingzi (Semen Cassiae),in order to evaluate the quality of Semen Cassiae decocting pieces effectively and accurately. Methods HPLC-PDA method was established to characterize the quality of spectrum of Semen Cassiae medicinal system architecture;quality of 11 batches of Semen Cassiae decocting pieces was characterized based on the number and chemical type of peaks on characteristic spectrum. The content of 6 characteristic index components, naphthopyrones and anthraquinones were characterized by indexes in characteristic spectrum. Correlation analysis of quality of Semen Cassiae was then performed with reference to the standard reference pieces. Results Taken as the reference substance, characteristic spectrum of batch 10 Semen Cassiae altogether contains 12 characteristic peaks, all characteristic peaks appeared on the chromatograms of 11 batches of Semen Cassiae. In 11 batches of Semen Cassiae, No.5, 11, 8, 1, 2 pieces contained higher effective index components, while No. 5, 11, 2, 9, and 7 pieces had high relevance with the reference piece (No. 10). Consolidated quality characterization and correlation analysis,the quality of No. 5,11,8,1,2,9,and 7 were excellent and dominant. Conclusion The HPLC method to analyze quality and quantity of phenolic components spectrum of 11 batches of Semen Cassiae is simple and accurate. The evaluation mode of quantity and quality and their correalation based on Semen Cassiae medical system, including systemic correlation and appilication validity, as it can provide a reliable methodological basis for the comprehensive quality evaluation of Semen Cassiae.
