Edema， as a common pathological phenomenon， is essentially the abnormal accumulation of body fluids in the interstitial spaces of human tissues and is often a direct manifestation of various underlying diseases， such as heart failure， impaired renal filtration function， or liver metabolic disorders. In the Western medical system， strategies for treating edema primarily focus on the use of diuretics to promote the excretion of excess fluid in the body， while simultaneously addressing the underlying causes through targeted treatment. However， long-term reliance on the use of diuretics may lead to a decrease in drug sensitivity and induce side effects， including electrolyte disorders such as hypokalemia and hypercalcemia， posing a potential threat to patients' overall health. Compared with Western medicine， traditional Chinese medicine （TCM） has demonstrated well-recognized and sustained efficacy in treating edema with its unique theoretical system. Zhulingtang， as a classic and commonly used TCM formula， is widely applied as it can effectively relieve edema and related symptoms. In recent years， ongoing in-depth studies on the treatment of edema with Zhulingtang have revealed multiple mechanisms of action of Zhulingtang， including the regulation of water metabolism and the reduction of inflammatory responses， thereby providing a solid theoretical basis for clinical practice. This review summarized the research progress on the treatment of edema with Zhulingtang in recent years and analyzed the active ingredients and action pathways of Zhulingtang. Additionally， the primary mechanisms of action and efficacy were systematically analyzed， so as to provide references for the clinical application of Zhulingtang in treating various types of edema， such as cardiogenic edema， renal edema， and hepatogenic edema. This review aims to offer theoretical support and practical guidance for clinicians in deciding treatment approaches， as well as references for subsequent in-depth studies， thereby promoting further development of TCM in the treatment of edema.

A virus was successfully isolated from a sick cat exhibiting clinical signs such as oral mu-cosal ulceration,nasal mucosal redness,and increased nasal secretions utilizing F81 cells.Through a comprehensive analysis as such PCR amplication,sequencing,morphology,serology,and animal re-gression tests,the virus was identified as a feline calicivirus and named FCV-BJ,an inactivated vac-cine was developed from this isolated strain its safety and efficacy were assessed.The results re-vealed that the isolated FCV-BJ strain exhibited characteristic serological and morphological fea-tures consistent with caliciviruses.Furthermore,inoculation of cats with the FCV-BJ demonstrated the strain is highly virulent and the cats manifested the clinical signs of feline calicivirus infection.For the vaccination trial,domestic cats were immunized with inactivated fifth-generation virus cell culture at varying dilutions,followed by a booster immunization after 21 days.Fourteen days after the challenge with the virus,cats immunized with 107.0 TCID50/mL or higher remained largely healthy,while all cats in the control group developed clinical signs of FCV.These findings suggest that the inactivated vaccine derived from the FCV-BJ isolate exhibits strong immunogenicity and protective efficacy at a minimum immunization dose of 107.0 TCID50/mL.This strain holds promise as a candidate for vaccine production,providing a valuable reference and foundation for future re-search and development of feline calicivirus vaccines.

Objective To investigate the changes and clinical significance of plasminogen activator inhibi-tor-1(PAI-1),transforming growth factor-β(TGF-β),vascular endothelial growth factor(VEGF),and inter-leukin-6(IL-6)in patients with tuberculous pleurisy and pleural fibrosis.Methods A total of 103 patients with tuberculous pleurisy and pleural fibrosis who were treated in a hospital from July 2020 to July 2023 were selected as the research subjects.After 2 weeks of treatment,they were divided into a significant effect group and a non-significant effect group based on the therapeutic efficacy of glucocorticoid treatment.The levels of PAI-1,TGF-β,VEGF,and IL-6 in serum and pleural effusion were compared before treatment,after 1 and 2 weeks of treatment.The correlation between the levels of PAI-1,TGF-β,VEGF,and IL-6 in serum and pleural effusion and the therapeutic efficacy was analyzed by Spearman correlation analysis.Pearson correlation analy-sis was used to analyze the correlation between the levels of PAI-1,TGF-β,VEGF,and IL-6 in serum and pleu-ral effusion and the levels of these indicators in pleural effusion after 2 weeks of treatment.A receiver operat-ing characteristic curve was drawn to analyze the predictive value of the levels of PAI-1,TGF-β,VEGF,and IL-6 in serum and pleural effusion for the efficacy of tuberculous pleurisy and pleural fibrosis patients after 1 and 2 weeks of treatment.Results The levels of PAI-1,TGF-β,VEGF,and IL-6 in serum and pleural effusion after 1 and 2 weeks of treatment in both groups were lower than those before treatment,and the levels of PAI-1,TGF-β,VEGF,and IL-6 in serum and pleural effusion after 1 and 2 weeks of treatment in the significant effect group were lower than those in the non-significant effect group,with statistically significant differences(P＜0.05).The levels of PAI-1,TGF-β,VEGF,and IL-6 in serum and pleural effusion after 1 and 2 weeks of treatment were negatively correlated with the efficacy(P＜0.05).The levels of PAI-1,TGF-β,VEGF,and IL-6 in serum and pleural effusion after 2 weeks of treatment were positively correlated(r=0.761,0.783,0.812,0.741,all P＜0.05).The area under the curve(AUC)of combined detection of serum and pleural effusion in-dicators after 1 and 2 weeks of treatment was greater than the AUC of individual indicators(P＜0.05).Con-clusion The levels of PAI-1,TGF-β,VEGF,and IL-6 in serum and pleural effusion of patients with tubercu-lous pleurisy and pleural fibrosis are related to the efficacy of treatment.The combined detection of PAI-1,TGF-β,VEGF,and IL-6 in serum and pleural effusion has good predictive value and can provide reference for clinical intervention.

ObjectiveTo observe the efficacy and safety of Tongguan Capsule（通冠胶囊）on ventricular remodeling in patients after acute myocardial infarction （AMI）， and to explore the possible mechanism. MethodsA total of 53 ST-segment elevation myocardial infarction （STEMI） patients were collected and randomly divided into 26 cases in the treatment group and 27 cases in the control group. The control group was given conventional therapy after percutaneous coronary intervention （PCI） for AMI， and the treatment group was given Tongguan Capsules （4.5 g each time， 3 times a day） on the basis of the control group. The course of treatment was 12 weeks. Echocardiographic data and stool samples were collected from subjects before and after the intervention， and left ventricular ejection fraction （LVEF）， left ventricular end-diastolic volume index （LVEDVi）， left ventricular end-systolic volume index （LVESVi）， left ventricular mass index （LVMi） were measured and calculated， so as to compare the number of cases of left ventricular remodeling in the two groups. At the same time， 16S rDNA sequencing was performed on the stool samples to analyze the diversity of gut microbiota （GM）， the composition of the GM， the GM difference between the groups； recording the incidence of major adverse cardiovascular events （MACEs） and adverse reactions of patients in the two groups during the study period； and performing Spearman's correlation analyses of the post-treatment flora data with LVEF， LVEDVi， LVESVi， LVM， and LVMi in the two groups. ResultsOne case fail to follow up in the treatment group and 2 cases fail to follow up in the control group， and 25 cases in each of the two groups were finally included in the analysis. LVEDVi， LVESVi， and LVMi of the control group after treatment were higher than those before treatment （P＜0.05）； after treatment， LVEDVi， LVESVi and LVMi in the treatment group were lower than those in the control group （P＜0.05）. Left ventricular remodeling occurred in 5 cases （20.00%） in the treatment group and 13 cases （52.00%） in the control group， and the incidence of left ventricular remodeling in the treatment group was lower than that in the control group （P=0.03）. After treatment， the ACE estimation and Chao estimation of bacterial abundance in the treatment group were higher than that before treatment and that in the control group （P＜0.05）. The treatment group showed an increase in Mycobacterium anisopliae phylum and a decrease in Mycobacterium thickum， Mycobacterium anisopliae phylum， and Mycobacterium patella phylum after treatment （P＜0.05）. When comparing between groups after treatment， the relative abundance of Prevotella， Agathobacter， Dialister， Eubacterium coprostanoligenes group was up-reuglated and the relative abundance of Enterococcus was down-regulated in the treatment group（P＜0.05 or P＜0.01）. There was no statistically significant difference in the incidence of MACEs and the occurrence of adverse reactions between groups during treatment （P＞0.05）. The results of correlation analysis showed that Prevotella were positively correlated with LVEF and negatively correlated with LVEDVi， LVESVi， LVM， and LVMi （P＜0.01）. Agathobacter group were negatively correlated with LVEDVi， LVESVi （P＜0.01）； Enterococcus group were positively correlated with LVESVi （P＜0.05）. ConclusionTongguan Capsules can improve ventricular remodeling in patients with acute ST-segment elevation myocardial infarction with better safety； its mechanism may be related to adjusting the enrichment of related bacteria such as Prevotella， Dialister and Enterococcus and other related bacterial genera， increasing the colonization and diversity of beneficial bacteria， and adjusting the structure of GM.

Objective To investigate the value of a clinical-CT radiomics model in predicting cervical lymph node metastasis(CLNM)of papillary thyroid carcinoma(PTC).Methods A total of 262 cases with PTC confirmed by pathology after surgery were selected.On CT arterial phase images,the PTC was outlined layer by layer via software 3D-slicer to extract CT radiomics features.The least absolute shrinkage and selection operator(LASSO)algorithm was used for dimensionality reduction and feature screening in relation to CLNM.The Mann-Whitney U test or Chi square test was performed to identify clinical parameters significantly associated with CLNM.The statistically significant CT radiomics features and clinical parameters were all selected for the multivariate logistic regression analysis to construct the clinical-CT radiomics model.The predictive efficiency of model was evaluated via the receiver operating characteristic(ROC)curve.Results The clinical-CT radiomics model demonstrated favorable predictive performance in both the training group[area under the curve(AUC)0.804,sensitivity 68.7％,specificity 82.4％]and the validation group(AUC 0.782,sensitivity 84.4％,specificity 61.8％).Conclusion The clinical-CT radiomics model demonstrates significant value in predicting CLNM of PTC,thereby,aiding in the development of personalized clinical plans for cervical lymph node(CLN)dissection.

Objective:To investigate the pathogenesis, selection of endovascular treatment (EVT) strategies, and efficacies of acute vertebrobasilar artery occlusion (AVBAO) of different lesion sites.Methods:One hundred and five patients with AVBAO, admitted to and accepted EVT in our hospital from February 2017 to September 2019, were chosen in our study. The data of disease onset, imaging findings, EVT status, perioperative complications, and prognoses of these patients were collected. According to DSA results, the involved lesions were divided into 4 sites: the upper segment of basilar artery (BA), the middle segment of BA, the lower segment of BA, and the intracranial segment of vertebral artery (V4 segment), and patients with tandem lesions would be recorded as distal lesions. The risk factors, EVT strategies, and prognoses 90 d after follow-up (modified Rankin scale [mRS] scores≤3: good prognosis) were compared in patients with 4 different lesion sites.Results:There were significant differences in etiological classifications and percentage of patients combined with atrial fibrillation among patients with 4 different lesion sites ( P<0.05). There was significant difference in proportion of patients accepted emergency stent implantation among patients with 4 different lesion sites ( P<0.05): those with lesions at the V4 segment had the highest proportion of patients accepted emergency stent implantation (79.55%), followed by those with lesions at the lower segment of BA (50.00%). There was significant difference in EVT time (the time from arterial puncture to successful recanalization of occluded vessels) among patients with 4 different lesion sites ( P<0.05): the EVT time in patients with lesions at the middle segment of BA was the shortest (87.5 [58.5, 130.8] min), and the EVT time in patients with lesions at the lower segment of BA was the longest (115.0 [81.0, 163.0] min). There was no statistical difference among patients with different lesion sites in good prognosis rate 90 d after follow-up ( P>0.05). Conclusion:The pathogenesis of patients with different AVBAO lesion sites is different, so different EVT strategies should be adopted.

Objective:To assess the role of arterial spin labeling (ASL) in detecting the blood-brain barrier (BBB) permeability of cerebral infarction lesions in patients with anterior circulation subacute ischemic stroke (SIS), and to evaluate the value of ASL in predicting hemorrhagic transformation (HT) of SIS patients after endovascular recanalization.Methods:A prospective analysis was performed. Patients with anterior circulation SIS who received endovascular treatment (EVT) in our hospital from January 2021 to September 2021 were enrolled. At 24 h before EVT and immediately after EVT, MRI scans of ASL sequences and dynamic contrast-enhanced magnetic resonance (DCE) sequence were completed, and Xper CT was performed; accordingly, imaging typing was performed. Head CT scan was performed 24-48 h after EVT to observe HT; according to the presence or absence of HT, these patients were divided into HT group and non-HT group; the relative cerebral blood flow (rCBF) values of ASL sequence parameters, volume transfer constant (K trans) of DCE sequence parameters and the differences of ASL, DCE and Xper CT imaging types between the two groups were compared. The weighted Kappa coefficient was used to test the consistency among ASL, DCE and Xper CT imaging types. Results:Among 22 eligible patients, 5 patients occurred HT (5/22, 22.72%). As compared with those in the non-HT group (1.14±0.04; 0.032[0.024, 0.039]/min), patients in the HT group had significantly higher rCBF value (1.57±0.18) and K trans (0.072[0.0455, 0.117]/min, P<0.05). There were significant differences in the distribution of ASL, DCE and Xper CT imaging types between the two groups ( P<0.05); among them, 4 out of 6 patients with ASL imaging type III, 4 out of 6 patients with DCE imaging type III, and 4 out of 5 patients with Xper CT imaging type III had HT. ASL sequence and DCE sequence had a high consistency in the imaging types (Kappa coefficient=0.941, 95%CI: 0.862-1.020, P<0.001). Conclusion:ASL can effectively evaluate the BBB permeability of cerebral infarction lesions in patients with anterior circulation SIS; patients with ASL imaging type III have a relatively high risk of HT.
