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.

AIM: To investigate the changes in ocular surface-related indicators and tear matrix metalloproteinase-9(MMP-9)levels in diabetic patients complicated with meibomian gland dysfunction(MGD), analyze the effects of diabetes mellitus on ocular surface status and tear MMP-9 levels in patients with MGD, and provide evidence for clinical diagnosis and treatment.METHODS: Prospective observational study.Patients with type 2 diabetes mellitus complicated with MGD who visited the Department of Ophthalmology of the hospital from June 2024 to December 2024 were enrolled(diabetes mellitus+MGD group), and patients diagnosed solely with MGD without a history of diabetes mellitus during the same period were recruited as the non-diabetic MGD group. Patients in the diabetes mellitus+MGD group were further subdivided into aglycosylated hemoglobin(HbA1c)<7.5% subgroup and an HbA1c≥7.5% subgroup based on HbA1c levels, and into a diabetes duration<10 y subgroup and a diabetes duration ≥10 y subgroup according to the duration of diabetes mellitus. Multiple ocular surface parameters, including the Ocular Surface Disease Index(OSDI)score and eyelid margin alteration score, as well as tear MMP-9 concentration, were measured in all participants, followed by between-group comparative analyses.RESULTS:Total of 101 patients(202 eyes)with type 2 diabetes mellitus combined with MGD were enrolled, including 56 males and 45 females with a mean age of 60.2±8.5 y. The non-diabetic MGD group consisted of 151 patients(302 eyes), with 82 males and 69 females and a mean age of 57.5±7.8 y.The HbA1c <7.5% group comprised 55 patients(110 eyes)aged 59.6±8.2 y; 31 males and 24 females. The HbA1c ≥7.5% group included 46 patients(92 eyes)aged 60.9±8.7 y; 25 males and 21 females.The subgroup with diabetes duration <10 y had 50 patients(100 eyes)aged 58.7±8.1 y; 28 males and 22 females, and the subgroup with duration ≥10 y consisted of 51 patients(102 eyes)aged 61.6±8.4 y; 27 males and 24 females. Patients in diabetes mellitus+MGD group exhibited higher OSDI scores, meibomian gland orifice scores, meibum expressibility scores, meibum quality scores, corneal fluorescein staining scores, and tear MMP-9 levels compared with non-diabetic MGD patients(all P<0.01), while tear film breakup time(BUT)and Schirmer test values were lower(all P<0.01).Among diabetic patients with MGD, the HbA1c≥7.5% subgroup had significantly higher OSDI score, meibomian gland orifice score, meibum expressibility scores, meibum quality scores, corneal fluorescein staining scores, and tear MMP-9 concentration than the HbA1c<7.5% subgroup(all P<0.05), accompanied by significantly shorter BUT and lower Schirmer I test results(all P<0.05). Similarly, the diabetes duration≥10 y subgroup showed significantly higher OSDI score, meibomian gland orifice score, meibum expressibility scores, meibum quality scores, corneal fluorescein staining scores, and tear MMP-9 concentration compared with the diabetes duration<10 y subgroup(all P<0.05), whereas BUT and Schirmer I values were significantly lower(all P<0.05).CONCLUSION: Diabetes mellitus may be associated with aggravated ocular surface damage in patients with MGD, accompanied by elevated tear MMP-9 levels. Poor glycemic control and longer disease duration are related to more severe ocular surface injury and higher tear MMP-9 levels. Tear MMP-9 may serve as a potential indicator for evaluating ocular surface inflammation and damage in diabetic patients with MGD, providing certain evidence for clinical treatment decision-making.

BACKGROUND:
Severe stroke has high rates of mortality and morbidity. This study aimed to investigate the clinical course, causes of worsening, and outcomes of severe ischemic stroke.
METHODS:
This prospective, multicenter cohort study enrolled adult patients admitted ≤30 days after ischemic stroke from nine hospitals in China between September 2017 and December 2019. Severe stroke was defined as a score of ≥15 on the National Institutes of Health Stroke Scale (NIHSS). Clinical worsening was defined as an increase of 4 in the NIHSS score from baseline. Unfavorable functional outcome was defined as a modified Rankin scale score ≥3 at 3 months and 1 year after stroke onset, respectively. We performed Logistic regression to explore baseline features and reperfusion therapies associated with clinical worsening and functional outcomes.
RESULTS:
Among 4201 patients enrolled, 854 patients (20.33%) had severe stroke on admission. Of 3347 patients without severe stroke on admission, 142 (4.24%) patients developed severe stroke in hospital. Of 854 patients with severe stroke on admission, 33.95% (290/854) experienced clinical worsening (median time from stroke onset: 43 h, Q1-Q3: 20-88 h), with brain edema (54.83% [159/290]) as the leading cause; 24.59% (210/854) of these patients died by 30 days, and 81.47% (677/831) and 78.44% (633/807) had unfavorable functional outcomes at 3 months and 1 year respectively. Reperfusion reduced the risk of worsening (adjusted odds ratio [OR]: 0.24, 95% confidence interval [CI]: 0.12-0.49, P <0.01), 30-day death (adjusted OR: 0.22, 95% CI: 0.11-0.41, P <0.01), and unfavorable functional outcomes at 3 months (adjusted OR: 0.24, 95% CI: 0.08-0.68, P <0.01) and 1 year (adjusted OR: 0.17, 95% CI: 0.06-0.50, P <0.01).
CONCLUSIONS:
Approximately one-fifth of patients with ischemic stroke had severe neurological deficits on admission. Clinical worsening mainly occurred in the first 3 to 4 days after stroke onset, with brain edema as the leading cause of worsening. Reperfusion reduced the risk of clinical worsening and improved functional outcomes.

Objective To investigate the clinical value of tumor-stroma ratio (TSR) in combination with KRAS, BRAF, NRAS, and microsatellite status for prognostic assessment of patients with colorectal cancer. Methods A total of 51 colorectal cancer cases meeting the inclusion and exclusion criteria were enrolled in this study. TSR levels were evaluated through optical microscopy. The KRAS/NRAS/BRAF mutation profiles and microsatellite status were determined in accordance with genetic testing results. Clinical data, pathological characteristics, and survival outcomes were systematically recorded. Results Among the 51 patients with colorectal cancer, 19 (37.3%) were categorized into the low stromal group and 32 (62.7%) into the high stromal group. Statistically significant differences were observed between the two groups in drug resistance, M stage, TNM stage, neural invasion, and microsatellite status (P<0.05). Compared with patients exhibiting high TSR, those with low TSR demonstrated significantly increased recurrence rates (5 vs. 21 cases, P=0.007), shortened disease-free survival (34.21 vs. 14.34 months, P=0.001), and reduced overall survival (38.79 vs. 23.09 months, P=0.021). Multivariate Cox regression analysis identified N stage, M stage, TNM stage, neural invasion, lymphovascular invasion, and TSR as independent risk factors for disease-free survival. N stage, M stage, neural invasion, lymphovascular invasion, and TSR emerged as independent prognostic factors for overall survival (P<0.05). Although the combined models of TSR with KRAS, NRAS, BRAF, and microsatellite status, respectively, demonstrated overall statistical significance (P<0.05), none of the dummy variables in these models reached individually statistical significance (P>0.05), and therefore cannot be considered independent prognostic factors. Conclusion TSR serves as an independent predictor of poor prognosis in advanced colorectal cancer, with patients exhibiting low TSR demonstrating a significantly higher risk of recurrence and metastasis than those with high TSR. For patients with colon cancer undergoing first-line palliative chemotherapy after postoperative recurrence, histopathological assessment of TSR in primary tumor sites holds prognostic value and may serve as a relevant factor for evaluating treatment resistance in clinical management.
