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 investigate the temporal predictive value of soluble triggering receptor expressed on myeloid cells-1(sTREM-1),procalcitonin(PCT),and myeloid-related protein 8/14(MRP8/14)for secondary acute respiratory distress syndrome(ARDS)in patients with severe pulmonary tuberculosis.Methods A retro-spective cohort study was conducted among patients with severe pulmonary tuberculosis admitted between January 2021 and December 2024.Patients were randomly assigned in an 8∶2 ratio to a training set(n=148)and a valida-tion set(n=37).Serum sTREM-1,PCT,and MRP8/14 were extracted from the electronic medical record at three time points:on admission(day 0),day 3,and day 7.Multivariable logistic regression was used to identify risk factors,and predictive performance was evaluated using receiver operating characteristic(ROC)curves.Results A total of 185 patients were included.In the training set(n=148),27 developed ARDS and 121 did not;in the validation set(n=37),7 developed ARDS and 30 did not.In the training set,serum sTREM-1,PCT,and MRP8/14 levels showed significant temporal changes(P<0.05).At admission,day 3,and day 7,levels of sTREM-1,PCT,and MRP8/14 were higher in the ARDS group than in the non-ARDS group(all P<0.05).At each time point,sTREM-1,PCT,and MRP8/14 were independently associated with the development of ARDS(P<0.05).In the training set,the combination of sTREM-1,PCT,and MRP8/14 at admission yielded the largest area under the ROC curve[AUC=0.976;95%confidence interval(CI),0.952～1.000],with a sensitivity of 88.9%and a specificity of 98.3%.In the validation set,the same combination achieved an AUC of 0.957(95%CI,0.895～1.000),with a sensitivity of 100.0%and a specificity of 86.7%.Conclusion Dynamic changes in sTREM-1,PCT,and MRP8/14 provide temporal predictive value for ARDS in patients with severe pulmonary tuberculosis,and the combined assessment improves early warning accuracy.

Objective:To study echinococcosis in the population and canine Echinococcus infection in Yushu City, Qinghai Province, and to explore the current epidemic situation and main transmission species of Echinococcus. Methods:In June 2023, a multi-stage sampling method was used to select 2 villages each in Shanglaxiu Township and Longbao Town, Yushu City, Qinghai Province. Each village included at least 100 permanent residents who had lived locally for at least 1 year and were 2 years old or older as the survey subjects. Enzyme-linked immunosorbent assay (ELISA) was used to detect serum antibodies against Echinococcus larvae in the population, and B-mode ultrasound was used for abdominal organ scanning. Meanwhile, on the main roads of Shanglaxiu Township and Longbao Town, canine feces were collected in designated areas at intervals. ELISA was used to detect the antigen of canine fecal Echinococcus, and PCR was used to detect the types of parasites ( Echinococcus multilocularis, Echinococcus granulosus and Echinococcus shiquicus). Results:A total of 511 residents were investigated in Yushu City, and the positive rate of serum Echinococcus larvae antibodies in the population was 26.22% (134/511), and the detection rate of echinococcosis B-mode ultrasound was 1.37% (7/511). Among them, the detection rates of B-mode ultrasound for cystic echinococcosis (CE) and alveolar echinococcosis (AE) were 1.17% (6/511) and 0.20% (1/511), respectively. The positive rate of Echinococcus antigen in 543 canine feces detected by ELISA was 12.89% (70/543). PCR was used to test 497 canine feces, and the detection rate of Echinococcus was 3.02% (15/497). Among them, the detection rate of Echinococcus multilocularis was higher than that of Echinococcus granulosus [2.82% (14/497) vs 0.20% (1/497)], and the difference was statistically significant (χ 2 = 11.44, P < 0.001). No Echinococcus shiquicus was detected. Conclusions:The positive rates of Echinococcus larvae antibodies in the population and canine Echinococcus antigen in Yushu City, Qinghai Province are both relatively high. There is a mixed epidemic of CE and AE, with Echinococcus multilocularis being the main species.

Objective:To construct a method for hepatitis B virus (HBV) DNA detection based on recombinase-mediated isothermal amplification (RAA)-clustered regularly interspaced short palindromic repeats and their associated protein 13a (CRISPR-Cas13a).Methods:Through the alignment and screening of HBV DNA sequences, a positive plasmid was constructed, and recombinase-aided amplification (RAA) primers and CRISPR RNA (crRNA) were designed. A method for detecting HBV DNA based on the RAA-CRISPR-Cas13a system was developed, and the specificity and sensitivity were evaluated. Utilizing the CRISPR-Cas13a system, 70 clinical samples from HBV DNA-positive patients with various viral loads collected at Beijing You′an Hospital from 2019 to 2021 were analyzed. The detection results were further compared with those results using real-time quantitative polymerase chain reaction (qPCR).Results:The optimal RAA amplification primers and crRNA were first screened using the RAA-CRISPR-Cas13a method, with the sensitivities for detecting HBV DNA standards and for clinical samples at 1 IU/ml and<10 IU/ml, respectively, demonstrating specificity for HBV DNA detection. Compared with qPCR (the gold standard), the detection consistency between the two methods was 100% (70/70).Conclusion:This study established a method for detecting HBV DNA by integrating recombinase-aided amplification (RAA) technology with CRISPR/Cas13a technology.

Transcranial temporal interference stimulation (tTIS) is a novel non-invasive neuromodulation technique with the potential to precisely target deep brain structures. This study explores the neural and behavioral effects of tTIS on the superior colliculus (SC), a region involved in eye movement control, in mice. Computational modeling revealed that tTIS delivers more focused stimulation to the SC than traditional transcranial alternating current stimulation. In vivo experiments, including Ca²⁺ signal recordings and eye movement tracking, showed that tTIS effectively modulates SC neural activity and induces eye movements. A significant correlation was found between stimulation frequency and saccade frequency, suggesting direct tTIS-induced modulation of SC activity. These results demonstrate the precision of tTIS in targeting deep brain regions and regulating eye movements, highlighting its potential for neuroscientific research and therapeutic applications.

OBJECTIVE: CRISPR-Cas protects bacteria from exogenous DNA invasion and is associated with bacterial biofilm formation and pathogenicity. METHODS: We analyzed the type I-F CRISPR-Cas system of Legionella pneumophila WX48, including Cas1, Cas2-Cas3, Csy1, Csy2, Csy3, and Cas6f, along with downstream CRISPR arrays. We explored the effects of the CRISPR-Cas system on the in vitro growth, biofilm-forming ability, and pathogenicity of L. pneumophila through constructing gene deletion mutants. RESULTS: The type I-F CRISPR-Cas system did not affect the in vitro growth of wild-type or mutant strains. The biofilm formation and intracellular proliferation of the mutant strains were weaker than those of the wild type owing to the regulation of type IV pili and Dot/Icm type IV secretion systems. In particular, Cas6f deletion strongly inhibited these processes. CONCLUSION The type I-F CRISPR-Cas system may reduce biofilm formation and intracellular proliferation in L. pneumophila.
