ObjectiveTo investigate the mechanism by which Wendantang regulates the silent information regulator 3 (SIRT3)/peroxisome proliferator-activated receptor-gamma coactivator-1α (PGC-1α) pathway to influence energy metabolism and thereby prevent and treat myocardial ischemia (MI) in a rat model of hyperlipidemia (HL). MethodsThirty SD rats were randomly assigned into five groups: control, model, low-dose (3.702 g·kg-1·d-1) Wendantang, high-dose (7.404 g·kg-1·d-1) Wendantang, and positive control (trimetazidine, 0.006 g·kg-1·d-1), with six rats in each group. The control group was fed normally, while the other groups were fed with a high-fat diet for six weeks for the modeling of HL. Subsequently, the drug intervention groups were administrated with corresponding drugs by gavage, and the control and model groups received an equivalent volume of normal saline for 14 days. One hour after the last gavage, the other groups except the control group were injected intraperitoneally with posterior pituitary hormone (30 U·kg-1) to induce MI. Electrocardiography (ECG) was employed to detect changes in the electrocardiogram. Hematoxylin-eosin staining was performed to observe cardiac pathological changes. Enzyme-linked immunosorbent assay was employed to measure the serum levels of cardiac troponin I(cTnI), myoglobin (MYO), and creatine kinase-MB (CK-MB). Colorimetry was used to determine the levels of total cholesterol (TC) and triglycerides (TG) in the serum and ATP, malondialdehyde (MDA), and superoxide dismutase (SOD) in the myocardial tissue. Western blot was employed to determine the protein levels of SIRT3, PGC-1α, adenosine monophosphate-activated protein kinase (AMPK), and phosphorylated AMPK (p-AMPK) in the myocardial tissue. Real-time PCR was employed to measure the mRNA levels of SIRT3, PGC-1α, and AMPKα in the myocardial tissue. ResultsCompared with the control group, the model group showed significant J-point deviation and elevation in the ECG image, increased heart rate, disarrangement of myocardial fibers with unclear boundaries, elevated levels of CK-MB, cTnI, MYO, TC, and TG (P<0.05, P<0.01), declined levels of SOD and ATP (P<0.01), down-regulated mRNA levels of SIRT3, PGC-1α, and AMPK (P<0.05), and down-regulated protein levels of SIRT3, PGC-1α, and p-AMPK (P<0.05). Compared with the model group, the low-dose and high-dose Wendantang groups and the trimetazidine group showed inhibited J-point deviation and elevation in the ECG image, slowed heart rate, reduced inflammatory cell infiltration, alleviated disarrangement of myocardial fibers, declined levels of CK-MB, cTnI, MYO, TC, and TG (P<0.05, P<0.01), elevated level of SOD (P<0.01), up-regulated mRNA levels of SIRT3, PGC-1α, and AMPK (P<0.05, P<0.01) and up-regulated protein levels of SIRT3, PGC-1α, and p-AMPK (P<0.05, P<0.01). ConclusionWendantang can effectively intervene in HL-associated MI in rats by reducing oxidative stress in myocardial cells, alleviating lipid metabolism disorders, and improving myocardial energy metabolism via the SIRT3/PGC-1α signaling pathway.

Premature ejaculation (PE) is the most common male sexual dysfunction with a high incidence, which seriously affects the relationship between a husband and wife and family harmony. Drug therapy is a first-line treatment for PE patients with premature ejaculation, and has achieved good efficacy, but the clinically available drugs are single and the abandonment rate is high. Coupled with the ineffective treatment of some patients, new drug research and development is imminent. This paper systematically reviews the current status of drug treatment for premature ejaculation, focusing on the research and development of new drugs and research progress in order to provide a reference for clinicians.

Peripartum cardiomyopathy (PPCM) often develops in the early postpartum period, especially within one month after delivery. However, in recent years, some cases of pregnancy-related cardiomyopathy with earlier or slightly later onset showed similar features with PPCM entirely. One patient with PPCM was admitted to the Department of Intensive Care Medicine of the First Affiliated Hospital of Bengbu Medical College on February 2022. After admission, the patient was exceptionally hemodynamically unstable and had repeated ventricular fibrillation. Apart from extracorporeal membrane oxygenation (ECMO) support, comprehensive treatment with cardiotonic agents and drugs to inhibit the "ventricular electric storm" was given. The cardiac structure and function were gradually improved. ECMO was successfully withdrawn on the 7th day after the onset of symptoms, and the patient was discharged after a full recovery. Early diagnosis and active intervention are the keys to improve the prognosis of patients with PPCM and avoid irreversible changes in cardiac structure.

BACKGROUNDThere has been no a specific scale to measure quality of life (QOL) for prostate cancer patients receiving androgen deprivation therapy (ADT) to date. This study aimed to develop and initially validate the scale to evaluate QOL for prostate cancer patients receiving ADT.
METHODSThe scale was developed following international recommendations. Moreover, the items were all generated through literature review and referenced questionnaires. After being reviewed by expert panelists, the revised scale was formed and then completed by a convenience sample of 200 prostate cancer patients from our hospital. Explore factor analysis (EFA) was applied to test the construct validity, then split-half reliability, Cronbach's alpha, and test-retest reliability were applied to assess the reliability and stability of the scale.
RESULTSThe revised scale contained 22 items and a total of 200 participants had completed the scale. One hundred participants were randomly selected from the total 200 participants to perform EFA with varimax rotation on the revised scale, and "hot flashes" item was deleted for low factor loading. We selected only 3 items from each factor, then, the final scale was formed with 18-items. We selected another 100 participants to perform the EFA again on the final scale. It was demonstrated that the structure with 6 factors explained 72.5% of total variance and factor loading value was above 0.40 in all items of the factors. Moreover, the split-half reliability coefficient, Cronbach's alpha, and test-retest reliability coefficient were calculated to be 0.74, 0.63, and 0.89, respectively, exhibiting good reliability on the whole.
CONCLUSIONSThe scale was identified to be a valid and reliable instrument to measure QOL for prostate cancer patients receiving ADT. Moreover, further research is needed to overcome the potential drawbacks.
