The study focuses on the concept of multifunctional traditional Chinese medicine (TCM) formulas and aims to evaluate the efficacy of the classical formula Xiaoyao San (逍遥散). Study employs the integrated evidence chain (Eff-iEC) method to organize, integrate, and evaluate its therapeutic efficacy in treating different diseases with the same therapy, and to investigate the feasibility of using Eff-iEC to evaluate the multifunctionality of TCM formulas. The evaluation covered Xiaoyao San's therapeutic effects on depression, premenstrual syndrome, chronic hepatitis, irritable bowel syndrome, dyspepsia, and menopausal syndrome. Concurrently, the Grading of Recommendations, Assessment, Development, and Evaluation (GRADE) system was used for evaluation, and authoritative medical documents were incorporated to corroborate the recognition of Xiaoyao San within the medical community. Depression and menopausal syndrome received higher ratings than other conditions in the Eff-iEC, GRADE, and Medical Community Recognition assessments. The Eff-iEC evidence grade for Xiaoyao San was rated as "High" or above for chronic hepatitis, irritable bowel syndrome, dyspepsia, and menopausal syndrome. Premenstrual syndrome received a "Moderate ⁺" rating. The GRADE evidence level was "Low-〇〇⨁⨁" for depression, premenstrual syndrome, and chronic hepatitis; "Moderate-〇⨁⨁⨁" for dyspepsia and menopausal syndrome; and "Very Low-〇〇〇⨁" for irritable bowel syndrome. Depression and menopausal syndrome had the highest inclusion frequency, appearing in all 4 categories. Premenstrual syndrome, chronic hepatitis, and dyspepsia are not recommended in Western medical guidelines, but they are included in TCM guidelines, the China National Basic Medical Insurance Drug List, and the China National Essential Drug List. Irritable bowel syndrome appears only in the China National Basic Medical Insurance Drug List and China National Essential Drug List. The evaluation results obtained using the Eff-iEC method align with Medical Community Recognition, providing an objective and comprehensive assessment of Xiaoyao San's efficacy. The findings suggest that Xiaoyao San has strong evidence for treating depression and menopausal syndrome. However, further experimental and clinical trials are needed to assess its efficacy in treating premenstrual syndrome, chronic hepatitis, irritable bowel syndrome, and dyspepsia. These results support the clinical efficacy and rational use of Xiaoyao San, expand the application scope of the Eff-iEC method, and offer valuable insights and methodological references for the comparative evaluation of multifunctional TCM formulas.

OBJECTIVE To construct a pharmaceutical care framework suitable for elderly individuals in nursing homes， so as to provide standardized content guidance for relevant practice. METHODS The initial items of pharmaceutical care content in n ursing homes were drafted through literature research and semi-structured interviews. Delphi method was used to conduct correspondence consultation among 38 experts from related fields in Xinjiang. The expert positive coefficient， authority coefficient， and Kendall’s W were calculated， and the analytic hierarchy process was employed to determine the weight of each item. After thorough discussion among the research team members， the pharmaceutical care framework suitable for elderly individuals provided by hospital pharmacists collaborating with nursing homes was finalized. RESULTS The questionnaire recovery rates for both rounds of expert correspondence consultation were 100%， with an authority coefficient ＞0.8 and Kendall’s W ranging between 0.153 and 0.185 （ P ＜0.001）. A total of 7 primary items and 31 secondary items were ultimately determined， with the consistency ratio of the item weights all being less than 0.1. Based on the integration of importance and feasibility， among the primary items， “assessment of pharmaceutical care needs” was assigned the highest weight. Among the secondary items， highly practical items such as “survey of pharmaceutical care needs”“guidance on usage and dosage”“methods for correctly reading drug package inserts”， and “self-management of common chronic diseases in the elderly” were assigned relatively high comprehensive weights. CONCLUSIONS The pharmaceutical care framework suitable for elderly individuals provided by hospital pharmacists collaborating with nursing homes， which was constructed based on the Delphi method， demonstrates good scientific validity and reliability， and can serve as a reference for pharmacists to provide pharmaceutical care in nursing homes.

Objective To investigate the epidemiological characteristics of malaria and provide a basis for developing improved prevention and control measures. Methods Data were obtained from the Chinese Disease Prevention and Control Information System. Malaria surveillance data for Nanning City from January 1,2023, to December 31,2024, were exported from the Infectious Disease Reporting Information Management Subsystem. The characteristics of the two groups of malaria cases were compared. Results A total of 103 imported malaria cases were reported in Nanning City in 2024, representing a 38.32% decrease compared with the same period of the previous year. No statistically significant difference were observed between cases reported in 2023 and 2024 in terms of average age, gender ratio, proportion of parasite species, and monthly reporting distribution;however, statistically significant differences were found in the proportion of reporting areas and current residence areas(χ2= 13.572 and 10.355, respectively; P = 0.001 and 0.035, respectively). The proportion of cases reported in Shanglin County and the proportion of cases residing in Shanglin County were both lower than those during the same period of the previous year. Conclusions The high aggregation of imported malaria cases in Nanning City has decreased. Medical institutions in areas other than Shanglin County should strengthen their vigilance against malaria.

Objective To explore the changes in intrarenal pelvic pressure and intrarenal temperature during F6.3 disposable electronic ureteroscopic lithotripsy through in vitro experiments. Methods Microchannels were established in the upper, middle, and lower calyces of ex vivo porcine kidneys. Spherical calcium oxalate stones(size:0.5 cm×0.5 cm×0.5 cm, 1-2 per target calyx)were placed via the microchannels. Temperature and pressure sensors were connected through sheaths and placed in each calyx. F6.3 disposable electronic ureteroscope combined with super-pulsed thulium fiber laser(pulse energy:0.1 J, frequency:300 Hz, power:30 W)was used for laser lithotripsy. During the procedure, normal saline(25±1)℃ was used for irrigation at a gradient of 10-150 mL/min(increasing by 10 mL/min). The temperature and pressure in the upper, middle, and lower calyces were observed and recorded at different irrigation flow rates, with each experiment repeated five times, and the average value was calculated. The intrarenal temperature and pressure changes within and between the three groups were compared. Results In the ex vivo porcine kidney model, intrarenal pelvic pressure increased linearly with the increase in irrigation flow rate. When the flow rate reached 90 mL/min, the average intrarenal pelvic pressure was(28.8±1.16)mmHg. When the flow rate was increased to 100 mL/min, the pressure exceeded the safety threshold, reaching(31.23±1.12)mmHg. With the increase in irrigation flow rate, intrarenal temperature gradually decreased. When the flow rate reached 20 mL/min, the maximum intrarenal temperature was 45.1 ℃. When the flow rate was increased to 30 mL/min, the maximum intrarenal temperature was 40.9 ℃, which did not exceed the safety threshold(43 ℃). Conclusion The in vitro experiments demonstrated that during F6.3 disposable electronic ureteroscopic lithotripsy, maintaining an irrigation flow rate of 30-90 mL/min kept the intrarenal pelvic pressure and intrarenal temperature within the safety thresholds, indicating that the procedure is safe and reliable.

Liver cancer (LC) remains one of the most prevalent tumors globally. Despite considerable advancements in its clinical treatment in recent years, the global burden of this disease is projected to increase. According to World Health Organization statistics, the number of LC deaths worldwide in 2022 was 760,000, ranking third among all cancers. Therefore, there is an urgent need to delve deeper into the realms of LC diagnosis, prognosis, and treatment. Proteomics, as an emerging technology leveraging mass spectrometry (MS)-based protein identification, liquid chromatography separation, and bioinformatics-driven data integration, enables the systematic characterization of proteome dynamics to address critical challenges in LC research. These challenges include the discovery of diagnostic and prognostic biomarkers as well as therapeutic targets. By scrutinizing the expression of specific proteins in both normal and cancerous tissues through high-throughput protein microarrays, researchers can uncover novel biomarkers. The use of these biomarkers alone or in combination with established ones holds the potential to significantly advance the fields of LC diagnosis, prognosis, and treatment. In general, the application of proteomics has significantly promoted the development of LC research. In this review, we summarized the latest advancements in the application of proteomics in LC, with a particular focus on diagnosis, prognosis, and treatment. We also concluded selected protein markers, aiming to offer guidance for further applications and present additional therapeutic targets for LC.

ObjectiveTo investigate whether Carthamus tinctorius L.-derived nanovesicles （CDNVs） can alleviate angiotensin Ⅱ （ANGⅡ）-induced cardiomyocyte （H9C2） hypertrophy by inhibiting the NF-κB signaling pathway and to elucidate the underlying molecular mechanisms. MethodsCDNVs were isolated and purified by ultracentrifugation combined with sucrose density gradient centrifugation， and their morphology and particle size distribution were identified by transmission electron microscopy and nanoparticle tracking analysis. Rat H9C2 cardiomyocytes were cultured in vitro and randomly divided into the normal control group （NC）， ANGⅡ （1.0 μmol/L） group， ANGⅡ+CDNVs group， and ANGⅡ+CDNVs+NF-κB activator 1 group. After 24 h of intervention， cell viability was detected by the CCK-8 assay， the expression of myocardial hypertrophy-related genes （ANP， BNP） was determined by qPCR， the relative cell area was measured by phalloidin staining， the expression of hypertrophy marker proteins and NF-κB pathway proteins （P-p65/p65， P-IκBα/IκBα） was examined by Western blot， and nuclear translocation of p65 was observed by immunofluorescence. Subsequently， NF-κB signaling pathway agonist activator 1 was added， and the expression of myocardial hypertrophy marker proteins and NF-κB pathway proteins was detected. ResultsCDNVs exhibited a typical round-like vesicle structure with an average particle size of 140.4 nm， which was consistent with the morphological characteristics of exosomes. ANGⅡ at concentrations of 0.1-1.0 μmol/L had no significant effect on cardiomyocyte viability. Compared with the NC group， ANGⅡ significantly upregulated the gene expression of ANP and BNP， increased the relative surface area of cardiomyocytes， elevated the levels of myocardial hypertrophy marker proteins and NF‑κB pathway proteins， and promoted the nuclear translocation of p65 （P<0.05）. Following treatment with CDNVs， all the above indicators were markedly reduced in comparison with the ANGⅡ group （all P<0.05）. However， all these experimental results were reversed after the addition of an NF‑κB agonist. ConclusionCDNVs alleviate ANGⅡ-induced H9C2 cell hypertrophy by inhibiting the NF-κB signaling pathway.

Background Pulmonary heart disease (PHD) is a critical cardiopulmonary disease in high-altitude areas, with pulmonary hypertension (PH) as its central pathological basis. Cold and hypoxia are vital environmental characteristics of high-altitude regions; however, their joint effect on the hospitalization risk for PHD and the underlying biological mechanisms remain unclear. Objective To evaluate the associations of cold, hypoxia, and their joint exposure with PHD hospitalization risk, and to investigate PH-related pathological changes induced by combined cold and hypoxic exposure and the intervention effects of γ-aminobutyric acid (GABA) in rats. Methods Based on hospitalization data for 92986 PHD cases from 333 hospitals in Gansu Province (2018–2022), a generalized additive model (GAM) with a quasi-Poisson distribution was used to assess the associations between daily mean temperature, atmospheric oxygen content (AOC) and the daily number of PHD hospitalizations. Four joint exposure categories were constructed using the fifth percentile of temperature (P₅, −7.90℃) and AOC grades (high or low) to assess the associations between different exposure combinations and daily PHD hospital admissions. To further investigate PH-related pathological changes and the intervention effects of GABA, 24 specific-pathogen-free male Sprague–Dawley rats were randomly assigned to four groups (n=6): normal temperature and normoxia control group (NC), combined cold and hypoxia exposure group (CH), combined exposure plus low-dose GABA intervention group (CHL), and combined exposure plus high-dose GABA intervention group (CHH). After 5 weeks, pulmonary hemodynamics and vascular remodeling were evaluated. Gut microbiota and inflammatory cytokines in lung tissue were assessed using 16S rRNA sequencing and enzyme-linked immunosorbent assay (ELISA), respectively. Results Each 1 g·m⁻³ decrease in AOC and each 1 ℃ decrease in daily mean temperature were associated with 2.6% (RR=1.026, 95%CI: 1.024, 1.027) and 1.8% (RR=1.018, 95%CI: 1.015, 1.020) increases in PHD hospitalization risk, respectively. Compared with the non-low-temperature and high-AOC group, the low-temperature and low-AOC group had the highest risk estimate (RR=1.673, 95%CI: 1.567, 1.785). Animal experiments demonstrated that, compared with the NC group, rats in the CH group showed shortened pulmonary artery acceleration time (PAT) and increased mean pulmonary artery pressure (MPAP), right ventricular hypertrophy index (RVHI), pulmonary arterial wall thickness, and α-smooth muscle actin (α-SMA) expression (P<0.05). The Observed Species and Chao1 indices of the gut microbiota were significantly lower in the CH group than in the NC group (P<0.05), while levels of tumor necrosis factor-alpha (TNF-α) and interleukin-1beta (IL-1β) in lung tissue were elevated (P<0.05). GABA intervention improved selected hemodynamic, vascular remodeling, and inflammatory indices. Conclusion Decreases in daily mean temperature and AOC are associated with an increased risk of PHD hospitalization, with the highest risk estimate observed in the low-temperature and low-AOC group. Animal experiments suggest that combined cold and hypoxic exposure induce PH-related pathological changes accompanied by alterations in the gut microbiota and pulmonary inflammation. GABA may partially ameliorate these changes.

ObjectiveMethylthioadenosine phosphorylase (MTAP) is found to be frequently deleted in malignant cancers, but the role of MTAP underlying metastasis and stemness of liver cancer remains far from clear. 5-fluorouracil (5-Fu) is clinically used in treating advanced liver cancer, however, chemoresistance is one of the major barriers impeding its efficacy. Liver cancer stem cells are considered to be the reservoir for tumor progression and chemoresistance. This study aims to explore the role of MTAP in regulating stemness and chemoresistance of 5-Fu in liver cancer. It is designed to elucidate the molecular mechanisms underlying MTAP-manipulated stemness. How MTAP influences metastasis and chemoresistance against 5-Fu in liver cancer is also elaborated. MethodsThe correlation of MTAP expression with stemness marker CD133 was evaluated by flow cytometry. Colony formation assays were conducted to analyze the tumorigenic ability. Western blot assays were applied to delineate the molecular mechanisms underlying MTAP-regulated stemness. Trans-well assays were conducted to analyze the metastatic potential of liver cancer cells.In vivo experiments were performed using subcutaneous xenograft and lung metastasis model on nude mice. Tumor size and weight were analyzed upon 5-Fu treatment. Metastatic nodules on lungs were evaluated. Immunohistochemical and TUNNEL assays were performed on slides obtained from tumor tissues. ResultsMTAP overexpression inhibited expression of CD133 and colony formation, which is further ablated by MTAP inhibitor. MTAP deprivation augmented stemness and colony formation, which is reversed by protein arginine methyltransferase 5 (PRMT5) overexpression but not its catalytically inactive counterparts. Critically, SRY-box transcription factor 2 (SOX2) was found to be a downstream regulator of MTAP/PRMT5, leading to stemness of liver cancer cells. MTAP overexpression suppressed SOX2 expression, while MTAP inhibition augmented expression of SOX2. Critically, MTAP overexpression inhibited migration and invasion of liver cancer cells. In vivo experiments in animal model found that MTAP deprivation promotes tumor growth and metastatic nodules of liver cancer. Additionally, MTAP overexpression inhibits tumor growth. Moreover, MTAP deprivation contributes to chemoresistance shown by increased tumor size and weight treated by 5-Fu. In contrast, MTAP overexpression led to further decline in tumor size and weight elicited by 5-Fu treatment. Accordingly, SOX2 was inhibited in tumor tissues after MTAP overexpression. Marker of proliferation Ki67 (Ki67) expression was dampened while apoptosis was found in MTAP-overexpressed tumor tissues. ConclusionIn this study, plethora of experimental studies collectively demonstrated that MTAP deprivation enhances stemness of liver cancer by regulating SOX2, exerting anti-cancer and chemoresistant role against 5-Fu in liver cancer. It is also worth noting that MTAP inhibition promoted metastasis of liver cancer. MTAP overexpression augmented tumor shrinking elicited by 5-Fu and SOX2 was involved in this process. These results concluded that MTAP/PRMT5/SOX2 signaling axis was involved in regulating stemness and chemoresistance of liver cancer. These findings help to exploit novel therapies by targeting stemness in MTAP-depleted liver cancer. It shed novel light on unveiling MTAP-regulated stemness in antagonizing 5-Fu treatment in liver cancer. It also adds mounting evidence to the theoretical basis for accomplishing personalized chemotherapy of liver cancer patients by targeting MTAP or its downstream PRMT5/SOX2.
