ObjectiveTo analyze the epidemiological characteristics of 8 major respiratory pathogens in influenza-like illness (ILI) cases with acute respiratory infections at fever clinics in Huangpu District, Shanghai from 2015 to 2024, and to provide a scientific basis for the prevention and treatment of respiratory diseases. MethodsA retrospective study was conducted in Huangpu District. Individuals meeting the case definition of ILI from 2015 to 2024 was registered. Their nasopharyngeal swabs were collected for pathogen detection. A total of 8 respiratory viruses were tested, including Influenza A virus (Flu A), Influenza B virus (Flu B), adenovirus (ADV), enterovirus/human rhinovirus (EV/HRV), human parainfluenza virus (HPIV), human coronavirus (HCoV), respiratory syncytial virus (RSV), and human metapneumovirus (HMPV). ResultsFrom 2015 to 2019, a total of 344 ILI cases were tested, of which 192 out of 344 cases (55.81%) were tested positive for single respiratory pathogen. From 2023 to 2024, 1 557 ILI cases were tested, with 572 out of 1 557 cases (36.74%) being positive for single pathogen. From 2023 to 2024, the positive rate of single pathogen in ILI cases was significantly lower than that in 2015‒2019 (χ²=42.66, P<0.001). Specifically, the positive rate of Flu A (χ²=74.43, P<0.001) decreased, while that of HPIV (χ²=8.66, P=0.003) increased, both with statistically significant differences. According to the seasonal pattern, the epidemic intensity of Flu A decreased in summer, while that of HPIV increased in summer and autumn. Demographic results showed statistically significant differences in the positive rates of EV/HRV between genders (χ²=22.38, P<0.001), with males exhibiting a higher positive rate than females. No statistically significant differences were identified in the positive rates of single pathogen among different age groups (χ²=4.42, P=0.110). Nevertheless, statistically significant differences were noted when comparing the positive rates of EV/HRV, Flu A, Flu B and HPIV across different age groups (P<0.05). EV/HRV was more commonly detected in the 15‒<25 age group (10.93%), while Flu A and HPIV had the highest positive rates in the ≥60 age group (21.24% and 4.77%). Flu B had the highest positive rate in the 25‒<60 age group (11.26%). 52.63% of cases with co-infections occurred during winter, with the primary pathogens involved being EV/HRV (9 cases) and HCoV (6 cases). The most prevalent combination of co-infection was Flu A with EV/HRV. ConclusionThe prevalence of respiratory pathogens among ILI cases from 2023 to 2024 exhibited notable fluctuations compared to that from 2015 to 2019. Therefore, influenza surveillance should be strengthened, and attention should also be paid to the prevalence of respiratory pathogens such as HPIV. These findings have profound implications for future research, surveillance, vaccine planning, and public health policy making.

ObjectiveTo observe the effects of Yangjing Zhongyutang （YJZYT） on mitochondrial biogenesis and oxidative stress damage mediated by the silent information regulator 1 （SIRT1）/peroxisome proliferator-activated receptor gamma coactivator-1alpha （PGC-1α） signaling pathway in cyclophosphamide （CTX）-induced rats with diminished ovarian reserve （DOR）， and to explore its mechanism in improving ovarian reserve function and follicular development. MethodsForty-two 8-week-old female SD rats with normal estrous cycles were randomly divided into a blank control group （n=7） and a model group （n=35）. Rats in the model group received a single intraperitoneal injection of CTX （90 mg·kg^-1） to establish the DOR model. After modeling， estrous cycles were monitored for 7 consecutive days， and model success was confirmed based on criteria for estrous cycle disruption. After successful modeling， rats were divided into groups for intervention： estradiol valerate group （0.09 mg·kg^-1）， and YJZYT high-， medium-， and low-dose groups （19.98， 9.99， 5.00 g·kg^-1）. The blank control group and model group were given an equal volume of distilled water by gavage. All groups received daily gavage once for 4 consecutive weeks. The general state， body weight， and ovarian wet weight of rats were observed and recorded， and the ovarian organ index was calculated. Enzyme-linked immunosorbent assay （ELISA） was used to measure serum levels of follicle-stimulating hormone （FSH）， luteinizing hormone （LH）， estradiol （E₂）， anti-Müllerian hormone （AMH）， superoxide dismutase （SOD）， and glutathione peroxidase （GSH-Px）. Hematoxylin-eosin （HE） staining was performed to observe ovarian histomorphological changes and follicular development status. Immunofluorescence was used to detect reactive oxygen species （ROS） expression levels. Colorimetric assays were employed to measure adenosine triphosphate （ATP） and malondialdehyde （MDA） content in ovarian tissues. Quantitative Real-time polymerase chain reaction （Real-time PCR） was used to detect mitochondrial DNA （mtDNA） copy number and the mRNA expression levels of key genes including SIRT1， PGC-1α， nuclear respiratory factor 1 （NRF1）， and mitochondrial transcription factor A （TFAM）. Western blot was performed to detect the protein expression levels of SIRT1， PGC-1α， NRF1， and TFAM. ResultsCompared with the blank group， rats in the model group exhibited disrupted estrous cycles， obviously reduced body weight， and decreased ovarian index （P<0.05）. Ovarian histopathology revealed cortical thinning， loose structure， and a significant reduction in both primordial and growing follicles （P<0.01）. Serum FSH and LH levels were significantly elevated （P<0.01）， while E₂ and AMH levels were obviously reduced （P<0.05， P<0.01）. ATP content and mtDNA copy number decreased in ovarian tissue （P<0.01）， ROS expression increased， MDA levels rose， while SOD and GSH-Px activities obviously decreased （P<0.05， P<0.01）， mRNA and protein expression levels of SIRT1， PGC-1α， NRF1， and TFAM were obviously downregulated （P<0.05， P<0.01）. After treatment， compared with the model group， body weight and ovarian index obviously recovered in rats administered various doses of YJZYT （P<0.05）， serum E₂ and AMH levels increased， while FSH and LH levels obviously decreased （P<0.05， P<0.01）， ovarian tissue ATP content and mtDNA copy number were up-regulated， ROS and MDA levels decreased， and antioxidant enzymes SOD and GSH-Px activity obviously increased （P<0.05， P<0.01）， Gene and protein expression levels related to the SIRT1/PGC-1α /NRF1/TFAM signaling pathway were obviously up-regulated compared to the model group （P<0.05， P<0.01）， HE staining revealed that ovarian structure gradually recovered to integrity in all treatment groups， with a obviously increase in the number of primordial and growing follicles （P<0.05， P<0.01）. Granulosa cells were neatly arranged， indicating marked improvement in ovarian function. ConclusionYJZYT may improve ovarian function and follicular development in rats with diminished ovarian reserve by activating the SIRT1/PGC-1α signaling pathway， promoting mitochondrial biogenesis， enhancing mitochondrial function， and alleviating oxidative stress damage.

Diabetic kidney disease（DKD） is a chronic kidney structural and functional disorder caused by diabetes. With the global prevalence of diabetes continuing to rise， DKD has gradually become a major cause of chronic kidney disease and end-stage renal disease（ESRD）， posing a serious threat to patients' quality of life and long-term health outcomes. Studies have shown that apoptosis plays a pivotal role in the development and progression of DKD， with its mechanisms involving abnormal activation of multiple signaling pathways such as Toll-like receptor 4（TLR4）/nuclear transcription factor-κB（NF-κB）/B-cell lymphoma-2（Bcl-2）/cysteinyl aspartate-specific proteinase（Caspase）-3， protein kinase R-like endoplasmic reticulum kinase（PERK）/eukaryotic initiation factor 2α（eIF2α）/activating transcript factor 4（ATF4）/CCAAT enhancer-binding protein homologous protein（CHOP）， phosphatidylinositol 3-kinase（PI3K）/protein kinase B（Akt）/glycogen synthase kinase-3β（GSK-3β）， Janus kinase 2（JAK2）/signal transducer and activator of transcription 3（STAT3）， adenosine monophosphate-activated protein kinase（AMPK）/mammalian target of rapamycin（mTOR） and silent information regulator 1（SIRT1）/tumor suppressor protein 53（p53）， thereby accelerating renal pathological damage in DKD. Extensive evidence-based medical studies have confirmed that traditional Chinese medicine（TCM）， leveraging its unique therapeutic advantages of multi-target， multi-component and multi-pathway approaches， has demonstrated remarkable efficacy and favorable safety profiles in treating DKD. Recent studies have demonstrated that active components of TCM can specifically target and modulate key effectors in apoptotic signaling pathways. Meanwhile， traditional compound formulations exert synergistic effects through multiple approaches such as replenishing deficiency and activating blood circulation， detoxifying and dredging collaterals， tonifying kidney essence， and removing stasis and purging turbidity， thereby comprehensively regulating critical pathological processes including endoplasmic reticulum stress and mitochondrial apoptosis pathways. This combined therapeutic approach of molecular targeting and holistic regulation provides novel strategies for delaying the progression of DKD. Based on this， this paper provides an in-depth analysis of key apoptotic signaling pathways and their regulatory mechanisms， while systematically summarizing recent research advances regarding the therapeutic effects of TCM active components， compound formulations， and proprietary Chinese medicines on DKD through modulation of these pathways， with particular emphasis on their underlying molecular mechanisms. These findings not only elucidate the modern scientific connotation and theoretical basis of TCM in treating DKD but also establish a solid theoretical and practical foundation for promoting the wider clinical application and further research of TCM in the field of DKD treatment.

ObjectiveTo explore the mechanism of Xianfang Huomingyin （XFHMY） in the treatment of type Ⅲ prostatitis （CP/CPPS） through network pharmacology， molecular docking， and animal experiments. MethodsThe traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform （TCMSP） and the Swiss Target Prediction database were used to screen and sort out the active ingredients and corresponding targets of XFHMY. The potential therapeutic targets of CP/CPPS were collected from online databases， such as the Online Mendelian Inheritance in Man （OMIM）， GeneCards， and DisGeNET. The potential core targets of XFHMY for treating CP/CPPS were further screened by constructing a protein-protein interaction （PPI） network and performing topological analysis. Meanwhile， the DAVID database was chosen to perform enrichment analysis on the intersection targets. On this basis， the AutoDock software was used for molecular docking， and the data was subsequently imported into the GraphPad Prism 8 software to generate a heat map. SD rats were divided into seven groups： A blank group， a sham operation group， a model group， low-， medium-， and high-dose XFHMY groups （3.645， 7.29， 14.58 g·kg^-1）， and a tamsulosin hydrochloride group （0.018 mg·kg^-1）. Hematoxylin-eosin （HE） staining was used to evaluate the pathological changes in prostate tissue. The inflammatory factor indicators of rats in each group were detected via enzyme-linked immunosorbent assay （ELISA）. Real-time fluorescence quantitative reverse transcription polymerase chain reaction （Real-time PCR） and Western blot were used to evaluate the mRNA and protein expression levels of phosphatidylinositol 3-kinase （PI3K）， protein kinase B （Akt）， and nuclear transcription factor-κB （NF-κB） p65 in prostate tissue. ResultsThe HE staining showed no significant signs of inflammatory cell infiltration in the prostate of the sham operation group compared to the blank group， while the model group had significantly inflammatory cell infiltration. The ELISA results showed that compared to the blank group， TNF-α， IL-1β， and COX-2 in the sham operation group had no significant differences. However， they were significantly higher in the model group （P<0.01）， indicating successful CP/CPPS modeling in rats. Compared with the model group， the low-，medium-and high-dose XFHMY group and the tamsulosin hydrochloride group showed significant decreases in TNF-α， IL-1β， and COX-2 （P<0.05，P<0.01）. The Real-time PCR analysis revealed that compared to the model group， the low-dose XFHMY group had reduced Akt and NF-κB p65 mRNA expression（P<0.05，P<0.01）. In the medium-and high-dose XFHMY group and tamsulosin hydrochloride group， PI3K， Akt， and NF-κB p65 mRNA levels decreased significantly（P<0.05，P<0.01）. Western blot analysis showed that compared to the model group， the low-dose XFHMY group had lower p-NF-κB p65/NF-κB p65 （P<0.05）. The medium- and high-dose XFHMY group and the tamsulosin hydrochloride group showed significant decreases in p-PI3K/PI3K， p-Akt-ser473/Akt， p-Akt-thr308/Akt， and p-NF-κB p65/NF-κB p65 （P<0.01）. ConclusionXFHMY may exert therapeutic efficacy on CP/CPPS by inhibiting the PI3K/Akt/NF-κB signaling pathway and reducing inflammatory responses. Additionally， NF-κB activation may be related to the activation of ser473 and thr308 sites.

Objective:To explore the clinical characteristics, diagnostic difficulties and optimization direction of treatment strategies of ectopic varicose veins rupture and bleeding in the colon of cirrhotic portal hypertension.Methods:A retrospective analysis was conducted on the clinical data of a patient with cirrhotic portal hypertension and ectopic varicose rupture and bleeding of the colon diagnosed clinically in the Department of Gastroenterology of the Xin′an International Hospital Affiliated to Jiaxing University in February 2025. Combined with the review of relevant literature, the diagnosis and treatment experience was summarized.Results:The patient was diagnosed by colonoscopy with rupture and bleeding of varicose veins in the descending colon, and the blood vessels were exposed.After hemostasis with tissue clips under emergency colonoscopy and the bleeding stopped, drug treatment for bleeding prevention was continued. Sequential endoscopic EcV treatment was planned to be scheduled at an alternative time.Conclusions:The incidence of rupture and bleeding of ectopic varicose veins in the colon due to cirrhotic portal hypertension is relatively low. The diagnosis is difficult, the risk of bleeding is high, and the treatment strategies are controversial. It is necessary to further optimize the diagnosis and treatment strategies in order to improve the therapeutic effect of patients.

Objective:To analyze the comprehensive efficiency of resource allocation in urban public hospitals in 21cities of Guangdong Province from 2019 to 2023,aiming at providing empirical evidence for future medical policy makers and hospital managers in resource allocation and management.Methods:Using Data Envelopment Analysis and Malmquist index to evaluate the efficiency of health resource allocation in public hospitals in Guangdong.Results:From 2019 to 2023,the comprehensive efficiency of urban public hospitals in Guangdong Province was mildly ineffective,only 7 cities showing relative effectiveness,and there were significant regional differences in efficiency.Malmquist index analysis showed that the total factor productivity of health resource allocation in urban public hospitals in the province decreased from 2019 to 2020 and kept increasing from 2020 to 2023,mainly due to the increasing of the technological progress index and the scale efficiency index.Horizontally,the total factor productivity of 9 cities in the province has increased,while the total factor productivity of 12 cities has decreased,with significant regional differences.The input-output redundancy analysis shows that only 6 cities have no input-output redundancy.Conclusion:The overall efficiency of resource allocation in urban public hospitals in Guangdong Province from 2019 to 2023 is relatively low,with significant regional differences.In the future,it is necessary to coordinate and plan resource allocation,focus on refined management,strengthen talent training and technological improvement,improve the operational efficiency of existing resources,and promote high-quality development of hospitals.

Objective To investigate the expression characteristics of poly(rC)-binding protein 1(PCBP1)in gastric cancer tissues and their clinical significances by bioinformatics analysis combined with experimental verification,and to identify its relationship with STIP1 homology and U-Box containing protein 1(STUB1).Specifically,this study aims to verify the expression patterns of PCBP1 and STUB1 in gastric cancer and determine their relationships with clinicopathological features by immunohistochemistry to provide a theoretical framework as well as potential intervention strategies for gastric cancer.Methods Data of PCBP1 expression in gastric cancer and adjacent tissues were obtained from TIMER 2.0 online analysis website.KEGG pathway enrichment analysis was performed using gastric cancer data(STAD)in the TCGA(the Cancer Genome Atlas)database,and its potential mechanism was determined.The main regulatory factor STUB1 was found in the fer-roptosis regulatory pathway.Subsequently,PCBP1 and STUB1 expressions in 33 cases of gastric cancer tissues and corresponding adjacent tissues were detected by immunohistochemistry.The collected cases were grouped according to different degrees of differentiation,age,gender,tumor size,depth of tumor invasion,TNM stage and pathological morphology.The positive expression rates of PCBP1 and STUB1 were observed.The correlation between the two proteins and the correlation between clinical and pathological features were analyzed by c2 test.Finally,the relationship between PCBP1 and STUB1 and malignancy of gastric cancer was further explored.Results Immunohistochemical results showed that the positive expression rate of PCBP1 in cancer tissues was 69.7%,which was significantly higher than that in adjacent tissues(48.5%).The positive expression rate of STUB1 in cancer tissues was 39.4%,which was lower than that in adjacent tissues(54.5%),statistically significant difference(P<0.05).The positive expression rate of PCBP1 was correlated with tumor differentiation,lymph node metastasis and Lauren classification(P<0.05),but not with patient's age,gender,depth of inva-sion,clinical stage,nerve infiltration,and intravascular tumor thrombus(P>0.05).The positive expression rate of STUB1 was correlated with tumor differentiation,depth of invasion,lymph node metastasis and Lauren classification(P<0.05).The Spearman correlation coefficient between PCBP1(cancer)and STUB1(cancer)was-0.413,with P=0.017(P<0.05),indicating that there was a significant negative correlation between them.Conclusion PCBP1 participates in the malignant progression of gastric cancer by regulating the main regulator STUB1 in the ferroptosis pathway.Theoretically,it provides a new insight into molecular mechanism as well as a potential therapeutic strategy for treating gastric cancer.
