Viral myocarditis(VMC)is a type of myocarditis caused by Coxsackievirus B3(CVB3)infection.Its pathogenesis is complex that includes direct viral action,host immune and inflammatory response,myocardial structure and function remodeling.The therapeutic effect of single target drugs is limited,while traditional Chinese medicine not only has antiviral effects,but also demon-strates systematic advantages in intervening in VMC due to its"multi-component,multi-target,and multi-pathway"characteristics.This article reviews the pathogenic mechanisms of CVB3-induced VMC,clarifies the interaction between CVB3 and host cells,and ex-plores the intervention mechanisms and developments of traditional Chinese medicine interventions for CVB3-induced VMC.At the same time,the prospects of traditional Chinese medicine treatment for CVB3-induced VMC in this study suggest that future research should strengthen the analysis of multi-target synergistic mechanisms based on traditional Chinese medicine formulas,combine artifi-cial intelligence,genomics,and gene editing technologies to predict drug-target interaction networks,establish standardized and per-sonalized system for integrated traditional Chinese and Western medicine treatment plans,and provide more effective strategies for the prevention and treatment of VMC.

Human Respiratory Stem Cells (RSCs) play a crucial role in the maintenance, repair and regeneration of the respiratory system. As a novel therapeutic method, stem cell therapy is a popular research direction in the medical field. And with the in-depth research on the mechanism of pneumonia caused by respiratory infections in recent years, the use of RSCs to explore pneumonia caused by respiratory infections and its therapeutic strategies has become a hot topic. In this paper, we firstly outlined the types of RSCs, summarized the mechanism of pneumonia caused by respiratory tract infections, discussed the advantages of RSCs application and the progress of culture differentiation, and elaborated the therapeutic exploration of RSCs in pneumonia caused by respiratory tract infections.

Objective To design a medical order pre-evaluation tool for perioperative prophylactic application of antibiotics,and to improve the efficiency of antibiotics management in hospitals during the perioperative period.Methods Using the open-source software R as the platform,a web application was built with tidy verse and shiny package based on related documents and guidelines.The discharge records of Affiliated Hospital of North Sichuan Medical College from April 1,2021,to December 31,2022,were retrospectively reviewed using the constructed pre-evaluation tool and compared with previous manual evaluation results using McNemar's Chi-squared test.Results This medical order pre-evaluation tool can quickly complete perioperative antibiotics order sampling,batch pre-evaluation,result statistics,visualization,and result output,and flexibly adjust the evaluation rules according to actual needs.The pre-evaluation tool is more efficient,with a review speed of 13.46 ms per medical record.Among the 2 642 discharge medical records of manual review,there was no significant difference between systematic pre-evaluation and manual evaluation results(ratio of prophylactic use:76.85%vs.78.21%)in terms of the type of use(preventive or curative)(P= 0.078).Among the 1 857 discharge records judged to be prophylactic for both manual and systematic reviews,the difference in unreasonable detection rate(39.90%vs.30.32%)was statistically significant(P＜0.001).Among the 63 typical ludicrous medical records confirmed by the review of clinical pharmacists with senior professional titles,60 were judged and limited by the pre-evaluation tool,and the detection rate of typical unreasonable was 95.24%.Conclusions The pre-evaluation tool based on R in this study can improve the efficiency of perioperative antibacterial drug evaluation.The evaluation conclusions and statistical results are reliable and are worthy of further development and application.

OBJECTIVE To evaluate the cost-effectiveness of vericiguat combined with standard treatment in the treatment of heart failure with reduced ejection fraction （HFrEF）. METHODS Based on the results of the VICTORIA trial and related literature， a three-state （including stable state of heart failure， hospitalized state of heart failure and death state） Markov model was constructed. The cycle length was 1 month， the time horizon was 20 years， the discount rate was 5%， and one time China’s per capita gross domestic product （GDP） in 2021 was the willing-to-pay （WTP） threshold. Cost-utility analysis was performed to evaluate the cost-effectiveness of vericiguat combined with standard treatment in the treatment of HFrEF. The output indicators included quality-adjusted life year （QALY） and incremental cost-effectiveness ratio （ICER）. The robustness of the results of the basic analysis was verified by one-way sensitivity analysis and probability sensitivity analysis. RESULTS The ICER of vericiguat combined with the standard treatment plan compared to the standard treatment plan alone was 444 341.95 yuan/QALY， which was more than WTP of this study （80 976 yuan/QALY）. One-way sensitivity analyses showed that the probability of cardiovascular death in both groups was the main influencing parameter for the robustness of the model， but they had little influence on the results of the basic analysis. The probabilistic sensitivity analysis displayed that under the WTP threshold of this study， the possibility of vericiguat combined with the standard treatment plan being more cost-effective was 2.6%. CONCLUSIONS Compared with the standard treatment plan， vericiguat combined with the standard treatment plan is not cost-effective in patients with HFrEF.

Objective Discuss the efficacy of pantoprazole and octreotide in treatment of gastrointestinal hemorrhage.Methods Selecting 220 cases patients with gastrointestinal hemorrhage.They were divided into two groups randomly.The observation group (115 cases) was given pantoprazole combined with octreotide.The observation group (105 cases) was given pantoprazole.The efficacy of pantoprazole and octreotide in treatment of gastrointestinal hemorrhage was evaluated by efficacy,perioperative index,SF-36 scores and adverse reaction during 1 month follow-up.Results The effective rate of observation group was significantly higher than that of the control group (P ＜ 0.05).The bleeding time of observation group was shorter than that of control group (P ＜ 0.05).The blood transfusion of observation group was less than that of control group (P ＜ 0.05).The hemoglobin level and pH value observation group was higher than that of control group (P ＜ 0.05).Before treatment,there were no statistical significance on SF-36 scores.After 1 months treatment,physiological function,physical function and pain scores of observation group was higher than that of control group(P ＜ 0.05).During 1 months follow-up,there were no statistical significance on adverse reaction between two groups.Conclusion The pantoprazole combined with octreotide had a good therapeutic effect on gastrointestinal hemorrhage.It could stop bleeding quickly,reduce blood loss and blood transfusion.It could improve the quality of life and use safely with worthy of clinical use.
