To explore the advantages of traditional Chinese medicine （TCM） and integrative TCM-Western medicine approaches in the treatment of diabetic microvascular complications （DMC）， refine key pathophysiological insights and treatment principles， and promote academic innovation and strategic research planning in the prevention and treatment of DMC. The 38th session of the Expert Salon on Diseases Responding Specifically to Traditional Chinese Medicine， hosted by the China Association of Chinese Medicine， was held in Beijing， 2024. Experts in TCM， Western medicine， and interdisciplinary fields convened to conduct a systematic discussion on the pathogenesis， diagnostic and treatment challenges， and mechanism research related to DMC， ultimately forming a consensus on key directions. Four major research recommendations were proposed. The first is addressing clinical bottlenecks in the prevention and control of DMC by optimizing TCM-based evidence evaluation systems. The second is refining TCM core pathogenesis across DMC stages and establishing corresponding "disease-pattern-time" framework. The third is innovating mechanism research strategies to facilitate a shift from holistic regulation to targeted intervention in TCM. The fourth is advancing interdisciplinary collaboration to enhance the role of TCM in new drug development， research prioritization， and guideline formulation. TCM and integrative approaches offer distinct advantages in managing DMC. With a focus on the diseases responding specifically to TCM， strengthening evidence-based support and mechanism interpretation and promoting the integration of clinical care and research innovation will provide strong momentum for the modernization of TCM and the advancement of national health strategies.

Objective:To explore the application value of dynamic monitoring of serum thyroid hormone(THs)levels in assessing the condition changes and prognosis of elderly patients with sepsis.Methods:Using a retrospective cohort study,a total of 120 elderly critically ill patients hospitalized in the Department of Critical Care Medicine from April 2020 to April 2023 were selected as research subjects,divided into a sepsis group(60 cases)and a non-sepsis group(60 cases).Sepsis patients were further divided into a survival group(43 cases)and a death group(17 cases)based on 28-day survival status.Serum THs,PCT,IL-6,and Lac were measured on the 1st,5th,and 10th days of hospitalization(d1,d5,dl0)for sepsis patients,and the Sequential Organ Failure Assessment(SOFA)score and Acute Physiology and Chronic Health Evaluation Ⅱ(APACHE Ⅱ)score were recorded.The datas of non-sepsis patients were sampled on d1.The incidence of non-thyroidal illness syndrome(NTIS)was statistically analyzed,and the dynamic changes of serum THs among different groups were compared.The correlation between THs and disease severity,as well as the predictive value of THs for 28-day mortality in sepsis,was analyzed.Results:①The incidence of NTIS was 78.33％(94/120),with a significantly higher incidence in sepsis patients(96.67％,58/60)compared to non-sepsis patients(60.00％),with statistical significance(P＜0.05).②Compared to non-sepsis patients,sepsis patients had significantly lower levels of TSH,T3,FT3,and T4 on d1,while rT3 was significantly elevated,with statistical significance(P＜0.05);the difference in FT4 levels was not statistically significant(P＞0.05).Pearson correlation analysis showed that T3 and T4 were negatively correlated with SOFA and APACHE Ⅱ scores(P＜0.05),while other THs indicators showed no correlation with SOFA and APACHE Ⅱ scores(P＞0.05).ANOVA results indicated that there was no statistically significant difference in T4 levels at the three time points,and its changes showed no obvious linear trend over time(P＞0.05);T3 was significantly lower on d1 than on d5 and d10,and showed an increasing trend with longer hospitalization,while SOFA and APACHE Ⅱ scores were significantly higher on d1 than on d5 and d10,showing a decreasing trend with longer hospitalization(all P＜0.05).③Compared to the survival group of sepsis patients,the death group had significantly higher levels of PCT on d10,IL-6 on d5 and d10,and Lac on d1,d5,and d10(P＜0.05).The death group had significantly lower levels of T3 and T4 on d1,significantly lower levels of TSH,T3,T4,and FT4 on d5,and significantly lower levels of TSH,T3,FT3,T4,and FT4 on d10,with statistical significance(P＜0.05).④Logistic regression analysis showed that independent risk factors for 28-day mortality in sepsis patients included T3 on d1 and T3,FT3,T4,FT4,and IL-6 on d10,with statistical significance(P＜0.05).ROC curve analysis indicated that serum levels of T3,FT3,T4,and FT4 on d10 had certain predictive value for 28-day mortality in sepsis patients(all P＜0.05),with T3,FT3,and FT4 showing good predictive value,and their AUCs were 0.875,0.872,and 0.861,respectively.The combined AUC for predicting 28-day mortality in sepsis patients using T3,FT3,and FT4 on d10 increased to 0.902.Conclusion:The incidence of NTIS was high in elderly sepsis patients,and the serum THs levels and their dynamic changes were closely related to the patients'condition changes.Continuous dynamic monitoring of serum THs levels could help to assess the progression of sepsis,and T3 may serve as an indicator for evaluating the progression and prognosis of sepsis.

Objective To examine the changing prevalence and antimicrobial resistance profiles of Burkholderia cepacia in 52 hospitals across China from 2015 to 2021.Methods A total of 9 261 strains of B.cepacia were collected from 52 hospitals between January 1,2015 and December 31,2021.Antimicrobial susceptibility of the strains was tested using Kirby-Bauer method or automated antimicrobial susceptibility testing systems according to a unified protocol.The results were interpreted according to the breakpoints released in the Clinical & Laboratory Standards Institute(CLSI)guidelines(2023 edition).Results A total of 9 261 strains of B.cepacia were isolated from all age groups,especially elderly patients.The proportion was 11.1％(1 032 strains)in children,significantly lower than the proportion in adults.About half(46.5％,4 310/9 261)of the strains were isolated from patients at least 60 years old and 42.3％(3 919/9 261)of the strains were isolated from young adults.Most isolates(71.1％)were isolated from sputum and respiratory secretions,followed by urine(10.7％)and blood samples(8.1％).B.cepacia isolates were highly susceptible to the five antimicrobial agents recommended in the CLSI M100 document(33rd edition,2023).B.cepacia isolates showed relatively higher resistance rates to meropenem and levofloxacin.However,the resistance rates to ceftazidime,trimethoprim-sulfamethoxazole,and minocycline remained below 8.1％.The percentage of B.cepacia strains resistant to levofloxacin was the highest compared to other antibiotics in any of the three age groups(from 12.4％in the patients＜18 years old to 20.6％in the patients aged 60 years or older).Conclusions B.cepacia is one of the clinically important non-fermenting gram-negative bacteria.Accurate and timely reporting of antimicrobial susceptibility test results and ongoing antimicrobial resistance surveillance are helpful for rational prescription of antimicrobial agents and proper prevention and control of nosocomial infections.

The application of botulinum neurotoxin(BoNT)in cosmetic procedures of the head and neck is well established.In recent years,however,its therapeutic scope has significantly expanded to include functional and pathological disorders within this anatomical region.This article reviews the use of BoNT as an important treatment modality for various head and neck disorders,encompassing movement disor-ders(such as laryngeal,craniocervical,middle ear,oromandibular,and cervical dystonia),peripheral nerve dysfunction(including multiple system atrophy,migraine,synkinesis and spasm following facial nerve palsy),upper aerodigestive tract dysfunction(e.g.,post-laryngectomy complications,cricopharyn-geal dysphagia,pharyngeal pouch,and retrograde cricopharyngeal dysfunction),and autonomic nervous disorders(such as sialorrhea and gustatory sweating syndrome).By leveraging its highly specific neuro-modulatory effects,BoNT provides a reversible,minimally invasive,and potent therapeutic alternative for conditions often refractory to conventional pharmacological or surgical interventions.This review systemat-ically examines the mechanisms of action,injection techniques,clinical efficacy,and safety profiles of BoNT in the above-mentioned diseases,and discusses future applications,aiming to offer comprehensive evidence-based guidance for clinical practice to otolaryngologists-head and neck surgeons.

Creutzfeldt-Jakob disease(CJD)is a rapidly progressive and fatal neurodegenerative disorder caused by prions,with certain infectivity and iatrogenic transmission risks.With the rapid progress and application of new dia-gnostic biomarkers and detection methods,as well as the construction and improvement of surveillance and reporting systems,the detection of CJD in patients domestically and internationally has shown an increasing trend year by year.Due to its long incubation period and heterogeneity of early symptoms,early identification and diagnosis of the disease is difficult,increasing the risk of transmission within medical institutions.Currently,there is a lack of con-sensus on the infection prevention and control of CJD.In order to timely identify and diagnose CJD as well as effec-tively block its transmission in medical institutions,this consensus summarizes 15 clinical concerns and formulates 24 specific recommendations based on the latest domestic and international research findings and clinical evidence,as well as combines with clinical practice,aiming to standardize healthcare-associated infection prevention and control measures for CJD and reduce its transmission risk in medical institutions.

Aim To study the effect of anti-PD-L1 monoclonal antibody on high-fat diet-induced athero-sclerosis in ApoE-/-mice.Methods Twenty-four ApoE-/-mice were randomly divided into the normal group,high-fat group,and high-fat+anti-PD-L1 mAb group.After 70 days,the blood samples were harves-ted.Blood vessels(aortic root to abdominal aorta)and liver from each groups were stained with Oil Red O.Hematoxylin-eosin staining(HE)was employed to vis-ualize structural changes in liver.Enzyme-linked im-munosorbent assay(ELISA)was applied to detect the serum levels of total cholesterol(CHO),triglyceride(TG),high-density lipoprotein(HDL-c),low-density lipoprotein(LDL-c)and inflammatory factors(IFN-γ,TNF-α,IL-1 β).Flow cytometry was used to detect the proportion of lymphocytes(CD4 and CD8).RT-PCR was utilized to assess the expressions of IFN-γ,TNF-α,IL-1 β,CD4 and CD8 in liver.Results Compared with the high-fat group,the treatment with anti-PD-L1 monoclonal antibody promoted vascular wall and liver lipid accumulation,and also up-regulated serum and liver content of cholesterol(CHO),triglyceride(TG)and high-density lipoprotein(HDL-c).Treatment with anti-PD-L1 monoclonal antibody up-regulated the con-tent of alanine aminotransferase(GPT)and aspartate aminotransferase(GOT)in serum and liver,but not al-kaline phosphatase(AKP).ELISA test indicated that treatment with anti-PD-L1 monoclonal antibody stimu-lated the serum level of IFN-γ,TNF-α and IL-1 β.Fur-thermore,the mRNA level of IFN-γ,TNF-α and IL-1 βin liver was also up-regulated after treatment with anti-PD-L1 monoclonal antibody.With flow cytometry,we observed that treatment with anti-PD-L1 monoclonal antibody promoted hepatic CD8+T and CD8+IFN-γ+T cell activation,but had no effect on CD4+IFN-γ+T cell activation under high-fat feeding conditions.Con-clusions Anti-PD-L1 monoclonal antibody adminis-tered under high-fat feeding conditions can damage liv-er function and aggravate atherosclerosis by activating liver CD8+IFN-γ+T cells.

Objective To explore the mechanism of Jiawei Jisheng Shenqi Decoction in improving the hypoxic microenvironment and antagonizing liver cirrhosis.Methods In vivo experiments were conducted using a rat model of carbon tetrachloride(CCL4)-induced liver cirrhosis.Rats were divided into normal,model,colchicine,JWJSSQ low-dose,JWJSSQ medium-dose,and JWJSSQ high-dose group.Pathological changes in liver tissues in each group were examined by hematoxylin and eosin(HE)and Masson staining,changes in serum liver function were detected using test kits,levels of hyaluronic acid(HA),laminin(LN),procollagen Ⅲ(PC Ⅲ),and collagen typeⅣ(COL4)were detected by enzyme-linked immunosorbent assay(ELISA),and protein expression levels of hypoxia-inducible factor-1α(HIF-1α),Notch1,Jagged1,and α-smooth muscle actin(α-SMA)were detected by Western blot.In vitro experiments were conducted in HSC-T6 cells,and the optimal concentration of CoCl2(100 μ mol/L,200μmol/L,400 μmol/L,600 μmol/L and 800 μmol/L)in the cultured cells and the optimal concentration of drug-containing serum(5％,10％,15％,20％)were determined by Cell Counting Kit-8(CCK-8)assay.The migration ability of cells in each group was detected by scratch testing,and changes in the apoptosis rates were determined by flow cytometry.Protein expression levels of HIF-1α,Notch1,Jagged1,α-SMA,matrix metallopeptidase 9(MMP9),and tissue inhibitor of metalloproteinases 1(TIMP-1)were detected by Western blot.Results In the in vivo experiments,liver swelling,inflammatory cell infiltration,collagen deposition,and the appearance of pseudolobules were significantly increased in the model group compared with those in the normal group.Serum levels of alanine aminotransferase(ALT),aspartate aminotransferase(AST),HA,LN,PCⅢ,and COL4 were significantly increased and albumin(ALB)was significantly decreased in the model group,while liver levels of HIF-1α,Notch1,Jagged1,and α-SMA proteins were significantly increased(P＜0.01).Liver swelling,inflammatory cell infiltration,and collagen deposition were significantly reduced in each treatment group compared with those in the model group,and the degree of fibrosis was reduced.Serum ALT,AST,HA,LN,PCⅢ,and COL4 were significantly decreased and ALB was significantly increased,while liver levels of HIF-1α,Notch1,Jagged1,and α-SMA proteins were also significantly decreased to varying degrees(P＜0.05).In the in vitro experiments,hypoxia promoted HSC-T6 migration and reduced apoptosis,increased the protein expression levels of HIF-1α,Notch1,Jagged1,α-SMA,and TIMP-1,and reduced the expression levels of MMP9(P＜0.01).Serum containing Jiawei Jisheng Shenqi Decoction inhibited HSC-T6 migration,promoted HSC-T6 apoptosis,lowered the expression of HIF-1α,Notch1,Jagged1,α-SMA,and TIMP-1 proteins,and enhanced the expression of MMP9 protein(P＜0.01).The inhibitory effect of Jiawei Jisheng Shenqi on HSC-T6 cell activation was reversed by the HIF-1α agonist dimethyloxalylglycine.Conclusions Jiawei Jisheng Shenqi Decoction can improve the hypoxic microenvironment via the HIF-1α/Notch pathway,thereby exerting an anti-liver cirrhosis effect.
