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.

Pulmonary hypertension has a high mortality rate,and although targeted therapy is available,it is still incurable,and the long-term prognosis for patients is poor.As a tyrosine kinase inhibitor,imatinib was approved for marketing in China in 2002 for the treatment of chronic myelogenous leukemia and other tumor diseases.In addition to the antitumor effects,imatinib was found to improve hemodynamics and exercise tolerance in patients with severe pulmonary arterial hypertension,but the safety was suboptimal.With the emergence of new formulations of imatinib targeted at the lungs,it is expected to become a new targeted drug for pulmonary arterial hypertension.

Allergic asthma is a complex，polygenic disease characterized by chronic inflammation and airway hyperresponsiveness. Fungus and dust mites are the most important inhaled allergens of allergic asthma，and often exist in the form of mixed allergens. In recent years，genetic studies have shown that several genes are associated with allergic asthma attacks. This article reviews the studies on the genes related to allergic asthma caused by dust mites and fungus，such as a disintegrin and metalloproteinase 33（ADAM33），interleukin-4（IL-4），glycoprotein A repetitions predominant（GARP），toll like receptor 3（TLR3），mannose-binding lectin 2（MBL2），chemokine（C-C motif）ligand 17（CCL17）and other genes .

Objective: To reveal the molecular mechanism underlying the compatibility of Salvia miltiorrhiza Bge (S. miltiorrhiza, Dan Shen) and C. tinctorius L. (C. tinctorius, Hong Hua) as an herb pair through network pharmacology and subsequent experimental validation. Methods: Network pharmacology was applied to construct an active ingredient-efficacy target-disease protein network to reveal the unique regulation pattern of S. miltiorrhiza and C. tinctorius as herb pair. Molecular docking was used to verify the binding of the components of these herbs and their potential targets. An H9c2 glucose hypoxia model was used to evaluate the efficacy of the components and their synergistic effects, which were evaluated using the combination index. Western blot was performed to detect the protein expression of these targets. Results: Network pharmacology analysis revealed 5 pathways and 8 core targets of S. miltiorrhiza and C. tinctorius in myocardial protection. Five of the core targets were enriched in the hypoxia-inducible factor-1 (HIF-1) signaling pathway. S. miltiorrhiza-C. tinctorius achieved vascular tone mainly by regulating the target genes of the HIF-1 pathway. As an upstream gene of the HIF-1 pathway, STAT3 can be activated by the active ingredients cryptotanshinone (Ctan), salvianolic acid B (Sal. B), and myricetin (Myric). Cell experiments revealed that Myric, Sal. B, and Ctan also exhibited synergistic myocardial protective activity. Molecular docking verified the strong binding of Myric, Sal. B, and Ctan to STAT3. Western blot further showed that the active ingredients synergistically upregulated the protein expression of STAT3. Conclusion The pharmacodynamic transmission analysis revealed that the active ingredients of S. miltiorrhiza and C. tinctorius can synergistically resist ischemia through various targets and pathways. This study provides a methodological reference for interpreting traditional Chinese medicine compatibility.

To address the issue of the difficulty in implementing non-invasive continuous blood pressure measurement technology in China,this study developed a high-performance synchronous electrocardiogram(ECG)and photoplethysmography(PPG)signal acquisition system.A PC-based human-computer interaction software platform was constructed,and continuous blood pressure measurement-related algorithms were integrated.Multiple feature parameters such as pulse wave transit time based on synchronous ECG and PPG signals were extracted,enabling non-invasive continuous blood pressure measurement.To verify the measurement accuracy of the system,tests and comparative verifications were carried out.The results demonstrated that the system could meet the requirements of relevant standards and have good application value.

Objective:To evaluate the antibacterial efficacy of ceftobiprole, vancomycin, linezolid, and daptomycin against Staphylococcus aureus (SAU) and coagulase-negative Staphylococcus (CNS) bloodstream infections, which can provide a reference for clinical medication. Methods:A total of 1 777 strains of staphylococci were isolated from blood culture of 51 hospitals within the Blood Bacterial Resistant Investigation Collaborative System (BRICS) from January to December in 2021. The dilution method was used to assess the minimum inhibitory concentrations (MIC) of ceftobiprole, vancomycin, linezolid and daptomycin on staphylococci. Additionally, the probability of target attainment (PTA) and cumulative fraction of response (CFR) of these medications in varied dosage regimens were predicted using Monte Carlo simulation.Results:Ceftobiprole demonstrated significant antibacterial activity against methicillin-resistant Staphylococcus aureus(MRSA), the MIC 50 and MIC 90 were 0.500 and 1.000 mg/L, respectively, and the MIC range was ≤0.060 to 4.000 mg/L.Meanwhile, the ceftobiprole-resistance rate of SAU was 0.1%(1/1 073), but the resistance rate of CNS was 7.7%(54/704). There was no evidence of staphylococcal resistance to daptomycin or vancomycin. Against methicillin-sensitive Staphylococcus aureus (MSSA), no resistance to the four drugs was observed. Monte Carlo simulation showed that standard drug regimens of ceftobiprole (500 mg once every eight hours) and daptomycin (6 mg·kg -1·d -1) achieved high PTA and CFR against staphylococcus.The current vancomycin and linezolid standard treatment for staphylococcal bloodstream infections had a low CFR. When vancomycin 1 000 mg once every eight hours was used, the CFRs of MRSA and MSSA were both≥90.0%, while the CFR of CNS was still less than 80.0%. CFR of linezolid against staphylococcus was ≥90.0% under the dosages of 600 mg once every eight hours. Conclusions:Ceftobiprole, vancomycin, linezolid and daptomycin all show strong antibacterial activity against staphylococcus.Ceftobiprole and daptomycin standard treatment represent adequate antibacterial efficacy against staphylococcal bloodstream infections. Furthermore, appropriate increase of the dosages of vancomycin and linezolid based on the MIC value and species of bacteria is necessary.

Enterotoxigenic Escherichia coli（ETEC）infection can induce watery diarrhea，leading to dehydration，electrolyte disturbance，and even death in severe cases. Recombinant B subunit/inactivated whole-cell cholera（rBS/WC）vaccine is effective in preventing ETEC infectious diarrhea. On the basis of the latest evidence on etiology and epidemiology of ETEC，as well as the effectiveness，safety，and health economics of rBS/WC vaccine，National Clinical Research Center for Child Health（The Children’s Hospital，Zhejiang University School of Medicine）and Zhejiang Provincial Center for Disease Control and Prevention invited experts to develop expert consensus on rBS/WC vaccine in prevention of ETEC infectious diarrhea. It aims to provide the clinicians and vaccination professionals with guidelines on using rBS/WC vaccine to reduce the incidence of ETEC infectious diarrhea.
