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.

Objective To investigate the correlation between indocyanine green(ICG)fluorescence imaging and lymph node metastasis of bladder cancer and its application value.Methods The clinicopathological data of 35 patients with bladder cancer(T1-T4aNxM0)treated in our hospital during Jun.2019 and Mar.2023 were collected.All patients underwent ICG submucous injection,and those with successful imaging received lymph node dissection under fluorescent guidance.After that,the remaining lymph tissue was cleared according to the standard lymph node dissection range,and the resected lymph tissue was subassembled for examination.Patients with non-imaging underwent standard pelvic lymph node dissection according to the routine procedure.Intraoperative lymph node imaging areas were recorded,and postoperative lymph node pathological data were collected.The correlation between fluorescence imaging patterns and lymph node metastasis in patients with different stages of bladder cancer was analyzed with correlation coefficients.Results The ICG fluorescence imaging rate was 91.43％(32/35),and there was no statistically significant difference in the imaging rate among patients with different stages of bladder cancer(P＞0.05).The fluorescence imaging range was significantly correlated with the stage(C=0.351,P=0.034).There was a significant correlation between the imaging range and lymph node metastasis in early-stage patients(C=0.619,P=0.022),but there was no significant difference in the lymph node metastasis rate in advanced patients with different imaging range(P＞0.05).In patients with full staging,the sensitivity of lymph nodes to predict metastasis was 60.00％(6/10),and the negative predictive value was 84.62％(22/26).In early-stage patients,the sensitivity and negative predictive value were 50.00％(1/2)and 93.75％(15/16),respectively.In advanced-stage patients,they were 62.50％(5/8)and 70.00％(7/10),respectively.Conclusion ICG fluorescence imaging rate of tracing lymph node metastasis is high,and the imaging range is significantly related to the tumor stage.For patients with early-stage(T1-T2)bladder cancer,the range of imaging helps to predict the risk of lymph node metastasis and guide the extent of lymph node dissection.Resection of multi-area imaged lymph nodes can comprehensively evaluate the lymphatic metastasis status of early-stage patients.

Objective:To evaluate the feasibility, safety and effects of tumor resection in the anterior space of the styloid process via transoral endoscopic medial parapterygomandibular ligament approach. Methods:This retrospective study included 24 patients who were diagnosed with tumors in the anterior space of the styloid process and treated with the transoral endoscopic medial parapterygomandibular ligament approach. Twenty-four patients who underwent surgery by traditional approach were selected on a 1∶1 ratio as control group. We compared the en bloc resection rate, the operation time, amount of blood loss, the postoperative pain VAS score, recurrence rate, length of hospital stay, complication rate between the two groups. Results:Among the 24 patients, pleomorphic adenoma was confirmed in 18 cases （75.0%）, basal cell adenoma in 2 cases （8.3%）, and neurilemmoma in 4 cases （16.7%）. In the transoral endoscopic group, the en bloc resection rate was 91.7%, the maximum tumor diameter was （42.2±12.2） mm, the operative time was （117.9±29.8）min, the blood loss was （36.7±18.7） mL, the postoperative pain VAS score （1.5±0.7）, no recurrence was observed, length of hospital stay was （10.8±2.9） d. Wound dehiscence occurred in one case in the transoral endoscopic group, and no other postoperative complication was observed. There were significant differences in the operation time, blood loss, the postoperative pain VAS score between the two groups, while no difference was found in gender, age, en bloc resection rate and length of hospital stay. Conclusion:The tumor resection in the anterior space of the styloid process via transoral endoscopic medial parapterygomandibular ligament approach was safe, minimally invasive and feasible.

Atherosclerosis (AS) is a chronic and progressive arterial disease. It is an important cause of the occurrence and development of cardiovascular and cerebrovascular diseases. With the development of Traditional Chinese Medicine (TCM), TCM has many advantages in the therapy of AS, with less adverse reactions. Studies have shown that TCM can resist AS, and the mechanism mainly belongs to regulating lipid metabolism, anti-lipid peroxidation, anti-inflammation, anticoagulation, and protecting the structure and function of vascular endothelial cells. The mechanism of TCM for AS is warranted to be studied systematically, and the chemical components need to be further clarified.

Periodontitis is an inflammatory disease that is characterized by progressive destruction of the periodontium and causes tooth loss in adults.Periodontitis is known to be associated with dysbiosis of the oral microflora,which is often linked to various diseases.However,the complexity of plaque microbial communities of periodontitis,antibiotic resistance,and enhanced virulence make this disease difficult to treat.In this study,using metagenomic shotgun sequencing,we inves-tigated the etiology,antibiotic resistance genes(ARGs),and virulence genes(VirGs)of periodontitis.We revealed a significant shift in the composition of oral microbiota as well as several functional pathways that were represented significantly more abundantly in periodontitis patients than in con-trols.In addition,we observed several positively selected ARGs and VirGs with the Ka/Ks ratio＞1 by analyzing our data and a previous periodontitis dataset,indicating that ARGs and VirGs in oral microbiota may be subjected to positive selection.Moreover,5 of 12 positively selected ARGs and VirGs in periodontitis patients were found in the genomes of respiratory tract pathogens.Of note,91.8％of the background VirGs with at least one non-synonymous single-nucleotide polymorphism for natural selection were also from respiratory tract pathogens.These observations suggest a potential association between periodontitis and respiratory infection at the gene level.Our study enriches the knowledge of pathogens and functional pathways as well as the positive selection of antibiotic resistance and pathogen virulence in periodontitis patients,and provides evidence at the gene level for an association between periodontitis and respiratory infection.
