ObjectiveTo establish an in vitro culture model of rat corpora cavernous smooth muscle cells (CCSMCs) using a modified tissue block adherence method. MethodsCorpus cavernosum smooth muscle tissue was digested with collagenase type I and subsequently cultured using an adherent method. Cells were purified via differential adhesion and identified through immunofluorescence and Western blotting. ResultsCCSMCs began to emerge from the tissue block after 3 days, increased significantly by day 7, and converged by day 12. Post-passage, CCSMCs exhibited strong proliferation and a “peak-to-valley” phenomenon. After purification, the cells tested positive for α-smooth muscle actin (α-SMA), confirming the successful establishment of the in vitro culture model. ConclusionThe modified tissue block adherence method is a cost-effective and efficient way to obtain high-purity CCSMCs.

OBJECTIVE To construct a whole-process management system for the smart pharmacy based on the integration of drug batch numbers and traceability codes, aiming to solve the problems of low upload rates and traceability difficulties of drug traceability codes in the central pharmacy, and to enhance its level of refined management and medication safety. METHODS Following the FOCUS-PDCA framework(find,organize,clarify,understand,select-plan,do,check,act), a drug batch number and traceability code management system was established by optimizing batch number management processes, introducing “pre-scan registration” technology, and establishing a dynamic “code pool” mechanism. Based on medical insurance upload data and operational performance indicators in our hospital from June to August 2025, the differences in management efficacy before and after the implementation of the system were compared and analyzed. RESULTS The drug batch number and traceability code management system was successfully established, achieving “one-object, one-code” whole-process association with batch numbers for inpatient drugs, especially split drugs. After the application of this system, the upload rate of inpatient drug traceability codes reached 100%, significantly higher than the average upload rate of inpatient drugs in other tertiary hospitals in our city (with the highest rate being only 23.22%, P <0.001). The inventory stocktaking error rate dropped from 0.9% to 0.3% (a decrease of 66.7%); the number of daily dispensing errors decreased from 1.43 to 0.37; the dispensing time (14.75 min) for temporary medical orders recovered to the routine level (14.42 min) prior to the system implementation. CONCLUSIONS By adopting the “pre-scan registration-code pool management-closed-loop traceability” model, this system enables traceability for individual drug products in their smallest packaging units, improves the upload rate of traceability codes, significantly reduces the medication dispensing error rate, and does not increase the time cost for temporary medical order dispensing, thereby balancing efficiency with closed-loop traceability.

Chronic heart failure (CHF) is a clinical syndrome characterized by impaired ventricular ejection function due to cardiac abnormalities, representing the terminal stage of most cardiovascular diseases. With its rising prevalence and significant impact on patients' quality of life, CHF has emerged as a major global public health concern. Current Western medicine treatments mainly involve the oral administration of the "new quadruple therapy" drugs and diuretics. Despite substantial progress in pathological research and clinical treatment, challenges persist, including considerable side effects, drug resistance, and marked interindividual variability in therapeutic response. Therefore, exploring and leveraging the advantages of traditional Chinese medicine (TCM) in treating CHF has become an urgent research priority. TCM has a millennia-long history in the prevention and treatment of heart failure, accumulating extensive clinical experience. Characterized by its multi-component and multi-target properties, TCM enables holistic regulation of multiple systemic functions and intervention in the progression of heart failure, demonstrating significant clinical relevance in its management. By employing therapeutic strategies such as warming Yang, promoting diuresis, replenishing Qi, nourishing Yin, and activating blood circulation, TCM effectively improves myocardial fibrosis, inhibits oxidative stress responses, enhances myocardial contractility, and ameliorates ventricular remodeling. Modern proprietary Chinese medicines derived from classic formulas, based on the theoretical foundation of traditional prescriptions, not only exhibit favorable clinical efficacy but also offer notable advantages in convenience, stability, and safety. This review systematically examined the significant therapeutic effects and underlying mechanisms of classical TCM formulas in the treatment of CHF, and provided an overview of the clinical application of modern proprietary Chinese medicines. It aims to provide new strategies for the clinical diagnosis and treatment of CHF.

OBJECTIVE To assess the bleeding risk signals associated with the concomitant use of direct oral anticoagulants (DOACs) and triazole antifungals, and to provide pharmacovigilance evidence for the safety evaluation and monitoring of combined clinical use. METHODS Adverse event reports involving the concomitant use of DOACs and triazole antifungals were extracted from the US FDA Adverse Event Reporting System (FAERS) from the first quarter of 2004 to the third quarter of 2025. Nine bleeding-related preferred terms (PTs) were selected. The Ω shrinkage measure, additive model, multiplicative model, and combined risk ratio method were employed to detect drug-drug interaction signals. The strength of positive signals was further analyzed based on the Ω shrinkage measure. RESULTS A total of 790 adverse event reports involving the concomitant use of DOACs and triazole antifungals were included, among which 229 reports involved nine bleeding-related PTs. A total of 13 signals were consistently identified as posit ive by all four methods. These signals involved six drug combinations: apixaban-fluconazole, apixaban-posaconazole, rivaroxaban-itraconazole, dabigatran etexilate-fluconazole, apixaban-voriconazole, and dabigatran etexilate-itraconazole. The Ω shrinkage measure showed that the apixaban-posaconazole combination exhibited stronger signals for bleeding ( Ω =2.73, Ω 025 =2.05) and hemoptysis ( Ω =2.17, Ω 025 =0.83); the apixaban-fluconazole combination exhibited stronger signals for hematoma ( Ω =2.30, Ω 025 =1.47) and hematuria ( Ω =1.71, Ω 025 =0.74); the rivaroxaban-itraconazole combination exhibited stronger signals for epistaxis ( Ω =2.01, Ω 025 =0.90) and hematoma ( Ω =1.93, Ω 025 =0.42); no positive Ω signals were observed for intracranial hemorrhage or upper gastrointestinal hemorrhage. CONCLUSION S This study suggests that the concomitant use of DOACs and triazole antifungals may increase the risk of bleeding-related events, with differences in signal strength and signal distribution across various drug combinations. In clinical practice, particular attention should be paid to the concomitant use of apixaban or rivaroxaban with strong cytochrome P450 3A4 or P-glycoprotein inhibitors such as posaconazole and itraconazole. For other DOAC-triazole antifungal combinations, close monitoring for bleeding-related manifestations and timely adjustment of anticoagulation or antifungal regimens are also warranted.

Andrological diseases have become an important public health problem threatening men's health worldwide, which significantly affects the quality of life of patients and brings a heavy disease burden. Western medicine often faces the dilemma of obvious side effects and limited efficacy. Traditional Chinese medicine has unique advantages in the prevention and treatment of andrological diseases and has accumulated rich clinical experience. Epimedii Folium, as a traditional Chinese medicine for strengthening kidney and Yang, exerts a key therapeutic effect on andrology diseases through multi-component synergy, multi-target regulation, and multi-pathway intervention. Recent studies have found that the main active components of Epimedii Folium, such as icariin, icariside, and icaritin, are the key material basis for the treatment of andrological diseases. The active components of Epimedii Folium can play a role in common andrological diseases such as erectile dysfunction, male infertility, and prostate cancer by regulating the activity of the nitric oxide/cyclic guanosine monophosphate (NO/cGMP) pathway, participating in oxidative stress response, regulating the secretion of hypothalamic-pituitary-gonadal axis hormones, improving spermatogenic dysfunction, and inhibiting the proliferation of cancer cells. However, the systematic action network and molecular mechanisms of the active components of Epimedii Folium have not been fully elucidated, thereby limiting its potential for clinical translation and application. In the future, it is necessary to combine cutting-edge technologies such as metabolomics, single-cell sequencing, and targeted nanoscale drug delivery systems, strengthening the research on the compatibility rules of active components and organ-specific delivery, providing a scientific basis for the development of innovative andrology traditional Chinese medicine formulas with international competitiveness, and promoting the innovation and breakthrough of andrology disease treatment modes.

High-altitude retinopathy(HAR)is a retinal vascular disorder induced by exposure to high-altitude environments. With the increasing popularity of high-altitude travel, mountaineering, and special occupational activities, worldwide, the incidence of HAR has risen, particularly among individuals with rapid or short-term exposure to elevated altitudes. Most cases of HAR are self-limiting and gradually resolve with descent to lower altitudes. However, severe cases may result in permanent visual function impairment if not recognized and managed promptly. This review systematically summarizes the epidemiology, diagnostic progress, pathogenesis, and prevention and treatment strategies of HAR, with particular emphasis on hypoxia-associated molecular pathways involved in retinal damage, and evaluates current evidence for clinical interventions. Deepened understanding of its pathological mechanisms and clinical management strategies facilitates early identification, targeted intervention, and ocular health protection for populations exposed to high altitudes.

Objective To screen genetic susceptibility markers related to serum HBeAg seroconversion by analyzing the association between host genetic susceptibility markers and seroconversion in HBeAg-positive patients with chronic hepatitis B (CHB), thereby providing potential molecular markers for clinical outcomes and prognosis evaluation in HBeAg-positive patients with CHB. Methods HBeAg-positive patients with CHB were recruited from the outpatient department of the Infectious Department, Second Affiliated Hospital of Air Force Military Medical University to establish a follow-up cohort. Based on whether HBeAg seroconversion occurred during follow-up, the subjects were divided into a case group (serum HBeAg with seroconversion) and a control group (serum HBeAg without seroconversion). MassARRAY SNP genotyping technique was used to detect SNPs of human genome DNA extracted from whole blood of the study subjects. Results Through association analysis between genetic susceptibility marker SNPs and seroconversion of serum HBeAg, it was found that: At the rs101206 8 locus, under the overdominant model, patients carrying the heterozygous GT genotype had a higher likelihood of serum HBeAg seroconversion (OR=1.73, 95%CI: 1.15-2.59, P=0.008); at the rs352140 locus, under the recessive model, patients carrying the TT genotype had a higher likelihood of serum HBeAg seroconversion (OR=1.77, 95%CI: 1.06-2.94, P=0.029); the rs1946518 locus, under the overdominant model, patients carrying the heterozygous GT genotype had a higher likelihood of serum HBeAg seroconversion (OR=1.73, 95%CI: 1.14-2.61, P=0.009); at the rs2306494 locus, under the dominant model, carrying the A allele (GA+AA) was identified as a negative factor for serum HBeAg seroconversion (OR=0.65, 95%CI: 0.42-0.99, P=0.043); at the rs20541 locus, under the recessive model, carrying the AA genotype was identified as a negative factor for serum HBeAg seroconversion (OR=0.31, 95%CI: 0.10-0.92, P=0.019); at the rs1057035 locus, under the dominant model, patients carrying the C allele (CT+CC) had a higher likelihood of serum HBeAg seroconversion (OR=1.78, 95%CI: 1.05-3.03, P=0.034). Therefore, the GT genotype at rs1012068 of DEPDC5 gene, TT genotype at rs352140 of TLR9 gene, GT genotype at rs1946518 of IL18 gene, and GG genotype at rs2306494 of TERF1 gene were conducive to seroconversion of serum HBeAg. The AA genotype at rs20541 of IL-13 gene and the TT genotype at rs1057035 of DICER1 gene were not conducive to seroconversion of serum HBeAg. Conclusion The genetic susceptibility markers (single nucleotide polymorphism loci) of host genetic genes in HBeAg-positive patients with CHB are associated with seroconversion of serum HBeAg, and the mechanisms by which these SNPs participate in serum HBeAg seroconversion require further investigation.

Objective::To investigate the correlation between maternal serum N-terminal pro-B-type natriuretic peptide (NT-proBNP) levels and gestational duration in pregnant women with pulmonary hypertension (PH).Methods::The study included pregnant individuals with PH stemming from mitral valve stenosis and mitral valve regurgitation (post-capillary PH) or pulmonary arterial hypertension (pre-capillary PH) who were admitted to Guangdong Provincial People’s Hospital between January 1, 2014 and December 31, 2020. In this retrospective cohort study, maternal serum NT-proBNP levels during pregnancy, along with other clinical data, were obtained from structured electronic medical records. These data included gestational age at delivery, echocardiographic parameters, laboratory findings, gestational duration, delivery mode, and other relevant clinical variables. Univariate and multivariate regression analyses were conducted to assess the association between NT-proBNP levels and gestational duration. Adjustments were made for potential confounding factors, and curve fitting and threshold effect analysis were employed to identify tangent points. Furthermore, stratified analyses were performed based on tricuspid regurgitation velocity, maternal age, and parity.Results::A total of 64 patients with post-capillary PH and 74 patients with pre-capillary PH were included in this study. Among patients with post-capillary PH, the results of multivariate regression analysis indicated a significant association between maternal NT-proBNP levels and gestational duration (β = -0.03, 95% confidence interval (CI) -0.05 to 0.00, P = 0.02). The fitted curve demonstrated a negative correlation between maternal NT-proBNP levels and gestational duration, with a significant break point at 379.9 ng/L ( P < 0.05). In the post-capillary PH group, the stratified analysis revealed a regression coefficient of -0.05 (95% CI:-0.06 to -0.04, P = 0.001) in patients with a tricuspid regurgitation velocity >340 mm/s. For patients >35 years old, the regression coefficient was -0.03 (95% CI -0.06 to -0.01, P = 0.02). In multiparous women, the regression coefficient was -0.03 (95% CI-0.06 to 0.00, P = 0.03). Conclusion::In pregnant women with pulmonary hypertension, maternal NT-proBNP levels are associated with gestational duration, particularly with an increased risk of preterm labor.
