Objective To analyze the monitoring data of cardio-cerebrovascular diseases prevention and control system in Yichang in 2022, and to provide data support and experience for the precise prevention and treatment of cardio-cerebrovascular diseases. Methods Acute cardiovascular and cerebrovascular event data were collected from the Yichang Cardio-cerebrovascular Events Monitoring System from January 1, 2022 to December 31, 2022. Descriptive analysis was conducted for the data collected. Statistical analysis was performed using SPSS 20.0 software, and a chi-square test was used to analyze the count data. Results A total of 37,217 cases of cardio-cerebrovascular events were monitored in Yichang in 2022. The crude incidence and the standardized incidence were 983.84/100,000 and 541.55/100,000, respectively. The incidence in males was higher than females (554.93/100,000 vs 428.91/100,000，χ² =464.52，P＜0.05). The top three diseases were cerebral infarction, acute myocardial infarction, and cerebral hemorrhage. The incidence of events increased with age, and 79.80% of the cases were over 60 years old. The main onset time was from May to August. Conclusion The use of the cardio-cerebrovascular events monitoring system in Yichang and the implementation of ^“mandatory reporting card^” monitoring can timely obtain the epidemic characteristics of the diseases, provide support for the precise formulation of prevention and control strategies and measures, reduce underreporting rates, and improve the monitoring system, which is worthy of reference and promotion.

Objective: To investigate the chemical compositions of Maxing Shigan Decoction (麻杏石甘汤, MXSGD) and elucidate its anti-influenza A virus (IAV) mechanism from prediction to validation. Methods: Ultra high-performance liquid chromatography-tandem mass spectrometry (UPLC-MS/MS) was employed to analyze the chemical compositions of MXSGD. Network pharmacology theories were used to screen and identify shared targets of both the potential targets of active ingredients of MXSGD and IAV. A protein-protein interaction (PPI) network was then constructed, followed by Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) enrichment analyses. The binding stability between core bioactive compounds and key targets was validated by molecular docking and dynamic simulations. A total of 24 BALB/c mice were infected with IAV to build IAV mouse models. After successful modelling, the mouse models were randomly divided into model, MXSGD high-dose (2.8 g/kg), MXSGD low-dose (1.4 g/kg), and oseltamivir (20.14 mg/kg) groups, with an additional normal mice as control group (n = 6 per group). The treatments were administered by gavage daily between 8:00 a.m. and 10:00 a.m. for five consecutive days. Upon completion of the administration, the body weight ratio, lung index, protein content in the bronchoalveolar lavage fluid (BALF), and the levels of inflammatory factors including interleukin (IL)-6 and tumor necrosis factor (TNF)-α in mice were measured to preliminarily analyze the therapeutic efficacy of MXSGD against IAV infection. Furthermore, the expression levels of mechanistic target of rapamycin (mTOR), hypoxia inducible factor (HIF)-1α, and vascular endothelial growth factor (VEGF) proteins in the HIF-1 signaling pathway, which was enriched by network pharmacology, were detected by Western blot. Results: A total of 212 chemical components in MXSGD were identified by the UPLC-MS/MS method. These chemical components can be classified into 9 primary categories and 31 secondary categories. After intersecting the chemical component targets with IAV-related targets, a total of 567 potential MXSGD components targeting IAV were identified. The construction of PPI network and the results of both GO and KEGG enrichment analyses revealed that the anti-IAV effects of MXSGD were associated with multiple pathways, including apoptosis, TNF, HIF-1, and IL-17 signaling pathways. The results of molecular docking demonstrated that the binding energies between the core compound 1-methoxyphaseollin and key targets including HIF-1α, mTOR, and VEGF were all lower than – 5.0 kcal/mol. Furthermore, molecular dynamics simulations confirmed the structural stability of the resulting complexes. Animal experiments showed that compared with the normal controls, IAV-infected mice showed significantly reduced body weight ratio, markedly increased lung index, protein content in BALF, and the levels of inflammatory factors such as IL-6 and TNF-α (P < 0.01), thereby causing damage to the lung tissue; consequently, the expression levels of mTOR, HIF-1α, and VEGF proteins in the lung tissues of these mice were significantly elevated (P < 0.01). However, after MXSGD treatment, the mouse models presented a significant increase in body weight ratio, as well as marked decreases in lung index, protein content in BALF, and the levels of inflammatory factors including IL-6 and TNF-α (P < 0.01). Furthermore, the therapy alleviated IAV-induced injuries and significantly downregulated the expression levels of mTOR, HIF-1α, and VEGF proteins in lung tissues (P < 0.01 or P < 0.05). Conclusion MXSGD exerts anti-IAV effects through multi-component, multi-target, and multi-pathway synergism. Among them, 1-methoxyphaseollin is identified as a potential key component, which alleviates virus-induced lung injury and inflammatory response via the regulation of HIF-1 signaling pathway, providing experimental evidence for the clinical application of MXSGD.

Objective: To investigate the trend in reported incidence of hepatitis B and to assess the effects of age, period, and birth cohort among people aged <30 years in Quzhou City, Zhejiang Province from 2005 to 2024. Methods: Reported cases of hepatitis B among people aged <30 years in Quzhou City from 2005 to 2024 were collected from the Infectious Disease Reporting Information System of Chinese Disease Prevention and Control Information System. The reported incidence was calculated. The average annual percent change (AAPC) was used to analyze the trend in reported incidence from 2005 to 2024. An age-period-cohort model was employed to analyze the effects of age, period, and birth cohort on the reported incidence of hepatitis B. Results: From 2005 to 2024, a total of 3 805 hepatitis B cases were reported among people aged <30 years in Quzhou City, with an average annual reported incidence of 31.61/100 000. The average annual reported incidence of hepatitis B was higher in males than in females (36.65/100 000 vs. 26.08/100 000, P<0.05). From 2005 to 2024, the reported incidence of hepatitis B among the entire people aged <30 years, as well as among males and females separately in Quzhou City, showed declining trends (AAPC=-9.887%, -10.415%, and -9.320%, respectively, all P<0.05). The age-period-cohort model analysis revealed that the incidence first decreased and then increased with age, declining from 4.21/105 in the age group of 0-<5 years to 2.07/105 in the age group of 10-<15 years, before rising to 22.49/105 in the age group of 25-<30 years. Using the 2010-2014 period as the reference, the risk of hepatitis B showed a decreasing trend over time. The RR value decreased from 1.842 (95%CI: 1.433-2.366) for 2005-2009 to 0.446 (95%CI: 0.294-0.675) for 2020-2024. Using the 2000-2004 birth cohort as the reference, the risk showed a decreasing trend with more recent birth years. The highest risk was observed in the 1980-1984 birth cohort, with an RR value of 4.731 (95%CI: 3.083-7.259). The age, period, and cohort effects on the reported incidence of hepatitis B among males and females were generally consistent with those observed in the entire population. Conclusions From 2005 to 2024, the reported incidence of hepatitis B among people aged <30 years in Quzhou City showed a declining trend, while exhibiting a pattern of first decreasing and then increasing with age. Furthermore, the risk of hepatitis B incidence demonstrated a decreasing trend over both time periods and birth cohorts.

Objective: To establish a progressive research strategy for “colonic components analysis - efficacy verification and mechanism exploration - gut microbiota”, screen pharmacodynamic substances, and investigate their mechanism via gut microbiota. Methods: The pharmacodynamics of Gegen Qinlian decoction (GQD) were assessed using a mouse model of dextran sulfate sodium-induced ulcerative colitis (UC). Ultra-performance liquid chromatography-quadrupole-orbitrap mass spectrometer was used to identify the prototype and metabolic components of GQD in the colon during UC. To analyze the structure and function of characteristic genera of GQD and its active components, 16S rRNA sequencing was performed. Results: We identified 67 prototypic and 14 metabolic components of GQD in the UC colon. The primary prototype components are flavonoids and alkaloids, including puerarin (PUE), baicalin (BAI), and berberine (BER). The metabolism was predominantly sulfonation. Efficacy verification showed that the main active components, puerarin, baicalin, and berberine, had good therapeutic effects on UC. The results of 16S rRNA gene sequencing showed that GQD improved UC by regulating the structure and function of the gut microbiota. The abundance of gut microbiota involved in the metabolism of the prototype components was influenced by the corresponding components. The function prediction results showed that PUE was the most comparable to GQD, with 24 consistent pathways. BAI and BER showed comparable gut microbiota regulation pathways. Characteristic pathways of BER include glucometabolic processes. Conclusion This study focused on the key issues in the gut microbiota pathway and developed a progressive research strategy to understand the transformation mechanisms of colonic components. This research systematically analyzed the active components and metabolic transformation of GQD in the colon during the pathological state of UC, as well as changes in the structure and function of the gut microbiota, clarified the mechanism of GQD and its active components in improving UC via the gut microbiota pathway.

Objective To investigate the effect of total paeony glycoside(TPG)on cerebral ischemia-reperfusion injury(CI/RI)of rats.Methods The rats were randomly divided into sham surgery(sham)group,CI/RI model group(simple CI/RI group),positive control group(nimodipine group,5 mg/kg),low-dose TPG group(TPG-L group,27 mg/kg),a high-dose TPG group(TPG-H group,54 mg/kg)and a high-dose TPG+NOD-like receptor thermal protein domain associated protein 3(NLRP3)activator diethyl dithiocarbamate(DDC)group(TPG-H+DDC group,54 mg/kg TPG and 30 mg/kg DDC),with 18 rats in each,administered once a day for 7 consecutive days.After the administration,the neurological deficit score of the rats was evaluated.Nissl staining microscopy was applied to observe neuronal activity in brain tissue.2,3,5-triphenyltetrazolium chloride(TTC)staining microscopy was applied to detect the area of cerebral infarction in rats.The level of interleukin-1β and IL-18 in brain tissue was measured by ELISA method.Western blot was applied to detect the expression of purinergic receptor P2X ligand-gated ion channel 7(P2X7R)/NLRP3 signaling pathway related proteins and pyroptosis related proteins such as apoptosis associated speck like protein containing a CARD(ASC)and cysteine protease 1(caspase-1)proteins in brain tissue.Results Compared with the sham group,the neurological deficit score,infarct area,level of IL-1β and IL-18 in brain tissue and protein expression of P2X7R,NLRP3,ASC,and caspase-1 in brain tissue of rats in the simple CI/RI group were significantly increased(P<0.05),while the proportion of Nissl body positive cells in brain tissue was significantly reduced(P<0.05).The change in corresponding indicators of rats in the nimodipine group,TPG-L group,and TPG-H group was opposite to those in the simple CI/RI group(P<0.05).NLRP3 acti-vator DDC antagonized the inhibitory effect of TPG on cell pyroptosis in CI/RI rats.Conclusions TPG may inhibit brain injury in CI/RI rats by down-regulating the P2X7R/NLRP3 pathway.

Glioma represents the most prevalent malignant tumor of the central nervous system, with chemotherapy serving as an essential adjunctive treatment. However, most chemotherapeutic agents exhibit limited ability to penetrate the blood-brain barrier (BBB). This study introduced a novel dual-targeting strategy for glioma therapy by modulating the formation of nanobody-driven protein coronas to enhance the brain and tumor-targeting efficiency of hydrophobic cisplatin prodrug-loaded lipid nanoparticles (C8Pt-Ls). Specifically, nanobodies (Nbs) with fibrinogen-binding capabilities were conjugated to the surface of C8Pt-Ls, resulting in the generation of Nb-C8Pt-Ls. Within the bloodstream, Nb-C8Pt-Ls could bound more fibrinogen, forming the protein corona that specifically interacted with LRP-1, a receptor highly expressed on the BBB. This interaction enabled a "Hitchhiking Effect" mechanism, facilitating efficient trans-BBB transport and promoting effective brain targeting. Additionally, the protein corona interacted with LRP-1, which is also overexpressed in glioma cells, achieving precise tumor targeting. Computational simulations and SPR detection clarified the molecular interaction mechanism of the Nb-fibrinogen-(LRP-1) complex, confirming its binding specificity and stability. Our results demonstrated that this strategy significantly enhanced C8Pt accumulation in brain tissues and tumors, induced apoptosis in glioma cells, and improved therapeutic efficacy. This study provides a novel framework for glioma therapy and underscores the potential of protein corona modulation-based dual-targeting strategies in advancing treatments for brain tumors.

Purpose: Cancer has become a significant major public health concern, making the discovery of new cancer markers or therapeutic targets exceptionally important. Elevated expression of tumor necrosis factor receptor superfamily member 12A (TNFRSF12A) expression has been observed in certain types of cancer. This project aims to investigate the function of TNFRSF12A in tumors and the underlying mechanisms. Materials and Methods: Various websites were utilized for conducting the bioinformatics analysis. Tumor cell lines with stable knockdown or overexpression of TNFRSF12A were established for cell phenotyping experiments and subcutaneous tumorigenesis in BALB/c mice. RNA-seq was employed to investigate the mechanism of TNFRSF12A. Results: TNFRSF12A was upregulated in the majority of cancers and associated with a poor prognosis. Knockdown TNFRSF12A hindered the colorectal cancer progression, while overexpression facilitated malignancy both in vitro and in vivo. TNFRSF12A overexpression led to increased nuclear factor кB (NF-κB) signaling and significant upregulation of baculoviral IAP repeat containing 3 (BIRC3), a transcription target of the NF-κB member RELA, and it was experimentally confirmed to be a critical downstream factor of TNFRSF12A. Therefore, we speculated the existence of a TNFRSF12A/RELA/BIRC3 regulatory axis in colorectal cancer. Conclusion TNFRSF12A is upregulated in various cancer types and associated with a poor prognosis. In colorectal cancer, elevated TNFRSF12A expression promotes tumor growth, potentially through the TNFRSF12A/RELA/BIRC3 regulatory axis.
