ObjectiveTo investigate the effect and mechanism of Bukan Yilidan on perimenopausal psycho-cardiac disease by mitochondrial autophagy mediated by dynamin-related protein 1(Drp1)/phosphatase and tensin homolog(PTEN) induced putative kinase 1(PINK1)/Parkin pathway. MethodsSixty rats were randomly divided into the blank group, model group, western medicine group(isosorbide mononitrate 7.2 mg·kg-1+sertraline hydrochloride tablets 18 mg·kg-1), Bukan Yilidan low, medium and high dose groups(2.59, 5.18, 10.35 g·kg-1), with 10 rats in each group. Except for the blank group, the rat model of perimenopausal psycho-cardiac disease was prepared by ovariectomy(OVX) combined with high-fat feeding, chronic unpredictable mild stress(CUMS) and subcutaneous multi-point injection of isoproterenol hydrochloride. After successful modeling, the general state and tongue image of rats were observed. The depression status of rats in vivo was evaluated by open field test, sucrose preference test, forced swimming immobility time and grip strength value, and the cardiac function of rats was evaluated by electrocardiogram and echocardiography. The levels of serum norepinephrine(NE), dopamine(DA) and 5-hydroxytryptamine(5-HT) were detected by enzyme-linked immunosorbent assay(ELISA), and biochemical detection was used to assess myocardial injury by measuring serum levels of high-density lipoprotein cholesterol(HDL-C), low-density lipoprotein cholesterol(LDL-C), triglyceride(TG), total cholesterol(TC), aspartate aminotransferase(AST), alanine aminotransferase(ALT), lactate dehydrogenase(LDH) and creatine kinase isoenzyme(CK-MB). Hematoxylin-eosin(HE) and Nissl staining were used to observe the pathological status of hippocampus and myocardial tissue in rats, the status of mitophagosomes in hippocampus and myocardium was observed by transmission electron microscope(TEM), and Western blot was used to detect the contents of Drp1, mitochondrial fusion protein 2(Mfn2), optic atrophy protein 1(OPA1), PINK1, Parkin, p62 and microtubule-associated protein light chain 3B(LC3B) in hippocampus and myocardium. ResultsCompared with the blank group, the food intake and water intake of rats in the model group decreased, the hair was dark yellow, the gloss and smoothness decreased, the spirit was depressed, the tongue was light purple or dark purple, accompanied by petechiae or ecchymosis, the sublingual collaterals were purple and black, and the tongue coating was white and smooth. The indexes of open field test, grip strength and sucrose preference of rats decreased significantly, and the immobility time of forced swimming increased significantly(P<0.01). Electrocardiogram and echocardiography showed that ST segment was significantly depressed, and left ventricular fractional shortening(LVFS) and left ventricular ejection fraction(LVEF) were significantly decreased(P<0.05, P<0.01). Pathological observation showed that the number of hippocampal neurons and myocardial cells decreased, and the structural damage was obvious. The levels of serum TC, TG, LDL-C, CK-MB, LDH, AST and ALT increased, while the levels of HDL-C, 5-HT, DA and NE decreased(P<0.05, P<0.01). TEM showed obvious mitochondrial damage in hippocampus and myocardial tissue. The protein expressions of Drp1, PINK1, Parkin and p62 in hippocampus and myocardium were increased, while the protein expressions of OPA1, Mfn2 and LC3BⅡ/Ⅰ were decreased(P<0.05, P<0.01). Compared with the model group, the mental state, body curling up, fear of cold and other symptoms of rats in each administration group were improved, and the degree of pale purple or dark purple tongue was reduced. The scores of open field test, grip strength, sucrose preference, LVFS and LVEF were increased, and the immobility time of forced swimming was shortened(P<0.05, P<0.01). The ST segment of electrocardiogram had a significant recovery(P<0.01), pathological observation showed that the damage of nerve cells and myocardial tissue was improved. The levels of serum TC, TG, LDL-C, CK-MB, LDH, AST and ALT decreased, while the levels of HDL-C, 5-HT, DA and NE increased(P<0.05, P<0.01). TEM showed that mitochondrial damage was reduced in hippocampal neurons and cardiomyocytes with visible mitochondrial autophagosomes. The protein expressions of Drp1, PINK1, Parkin and p62 in hippocampus and myocardium were decreased, while the protein expressions of OPA1, Mfn2 and LC3BⅡ/Ⅰ were increased(P<0.05, P<0.01). ConclusionBukan Yilidan can alleviate depression, lipid metabolism disorder and myocardial ischemia injury in rats with perimenopausal psycho-cardiac disease, and its mechanism may be related to inhibiting Drp1/PINK1/Parkin signaling pathway and enhancing mitochondrial autophagy.

BACKGROUND:
Meningeal metastasis (MM) is a form of malignant metastasis where tumor cells spread from the primary site to the pia mater, dura mater, arachnoid, subarachnoid space, and other cerebrospinal fluid compartments. Lung cancer is one of the most common malignant tumor types with MM. MM not only signifies that the lung cancer has progressed to an advanced stage but also leads to a range of severe clinical symptoms due to meningeal involvement. Currently, the risk factors associated with the development of MM are not fully elucidated. The aim of this study was to investigate the risk factors for MM in patients with lung adenocarcinoma (LUAD) who underwent non-surgical interventions, in order to identify LUAD patients at high risk for MM.
METHODS:
This retrospective study analyzed the clinical data of patients diagnosed with LUAD at the First Affiliated Hospital of Zhengzhou University from January 2020 to July 2024. Missing data were imputed using multiple imputation methods, and risk factors were identified through LASSO, univariate, and multivariate Logistic regression analyses.
RESULTS:
A total of 170 patients with LUAD were included in this study and divided into two groups: 87 patients with MM and 83 patients without MM. Univariate and multivariate Logistic regression analyses revealed that younger age at diagnosis (P=0.004), presence of the epidermal growth factor receptor (EGFR) L858R gene mutation (P=0.008), and concurrent liver metastasis at baseline (P=0.004) were independent risk factors for developing MM in LUAD patients who did not undergo surgical intervention. Conversely, higher baseline globulin levels (P=0.039) and the presence of the anaplastic lymphoma kinase (ALK) gene mutation (P=0.040) were associated with a reduced risk of MM development.
CONCLUSIONS
Age at diagnosis, EGFR L858R mutation status, ALK gene mutation status, concurrent liver metastasis, globulin levels at baseline were significantly associated with the risk of developing MM in patients with LUAD patients who did not undergo surgical intervention. For patients diagnosed at a younger age, carrying the EGFR L858R mutation, or presenting with baseline liver metastasis, early implementation of tertiary prevention strategies for MM is crucial. Regular monitoring of MM status should be conducted in these high-risk groups.

Respiratory syncytial virus (RSV) is an enveloped, negative-sense, single-stranded RNA virus of the Orthopneumovirus genus of the Pneumoviridae family in the order Mononegavirales. RSV can cause acute upper and lower respiratory tract infections, sometimes with extrapulmonary complications. The disease burden of RSV infection is enormous, mainly affecting infants and older adults aged 75 years or above. Currently, treatment options for RSV are largely supportive. Prevention strategies remain a critical focus, with efforts centered on vaccine development and the use of prophylactic monoclonal antibodies. To date, three RSV vaccines have been approved for active immunization among individuals aged 60 years and above. For children who are not eligible for these vaccines, passive immunization is recommended. A newly approved prophylactic monoclonal antibody, Nirsevimab, which offers enhanced neutralizing activity and an extended half-life, provides exceptional protection for high-risk infants and young children. This review provides a comprehensive and detailed exploration of RSV's virology, immunology, pathogenesis, epidemiology, clinical manifestations, treatment options, and prevention strategies.
