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 implementation and evaluate the effectiveness of health management services for patients with type 2 diabetes mellitus (T2DM) in Urumqi City from 2017 to 2021, so as to provide the reference for enhancing T2DM patients management. Methods: Data on the rates of record establishment, health management and standardized management for T2DM patients, and blood glucose control rate in managed patients in Urumqi City from 2017 to 2021 were collected through the quarterly reports on basic public health service management from the Weining Health Platform System. The trends in the four management indicators, and the differences between urban and rural areas were analyzed. Results: The rates of record establishment, health management and blood glucose control rate in managed patients in Urumqi City were 46.94%, 38.37% and 59.92%, respectively, showing upward trends from 2017 to 2021 (all P<0.05). The rate of standardized management was 75.89%, showing a downward trend (P<0.05). The rate of record establishment was higher in urban areas than in rural areas (47.76% vs. 40.56%, P<0.05). The rates of standardized management and blood glucose control in managed patients were lower in urban areas than in rural areas (75.18% vs. 81.46%, 58.93% vs. 67.64%, both P<0.05). The rate of health management was 38.39% in urban areas and 38.24% in rural areas, with no statistically significant difference (P>0.05). The trends in the rates of record establishment, health management and standardized management in both urban and rural areas were consistent with those in the overall population. Conclusions From 2017 to 2021, the rates of record establishment, health management and blood glucose control in managed patients in Urumqi City showed upward trends, while the rate of standardized management exhibited a downward trend. There were urban-rural differences in the rates of record establishment, standardized management and blood glucose control in managed patients.

Hepatocellular carcinoma (HCC) expresses abundant glycolytic enzymes and displays comprehensive glucose metabolism reprogramming. Aldolase A (ALDOA) plays a prominent role in glycolysis; however, little is known about its role in HCC development. In the present study, we aim to explore how ALDOA is involved in HCC proliferation. HCC proliferation was markedly suppressed both in vitro and in vivo following ALDOA knockout, which is consistent with ALDOA overexpression encouraging HCC proliferation. Mechanistically, ALDOA knockout partially limits the glycolytic flux in HCC cells. Meanwhile, ALDOA translocated to nuclei and directly interacted with c-Jun to facilitate its Thr93 phosphorylation by P21-activated protein kinase; ALDOA knockout markedly diminished c-Jun Thr93 phosphorylation and then dampened c-Jun transcription function. A crucial site Y364 mutation in ALDOA disrupted its interaction with c-Jun, and Y364S ALDOA expression failed to rescue cell proliferation in ALDOA deletion cells. In HCC patients, the expression level of ALDOA was correlated with the phosphorylation level of c-Jun (Thr93) and poor prognosis. Remarkably, hepatic ALDOA was significantly upregulated in the promotion and progression stages of diethylnitrosamine-induced HCC models, and the knockdown of A ldoa strikingly decreased HCC development in vivo. Our study demonstrated that ALDOA is a vital driver for HCC development by activating c-Jun-mediated oncogene transcription, opening additional avenues for anti-cancer therapies.

OBJECTIVE: Gastric cancer (GC) is one of the most common malignancies seen in clinic and requires novel treatment options. Morin is a natural flavonoid extracted from the flower stalk of a highly valuable medicinal plant Prunella vulgaris L., which exhibits an anti-cancer effect in multiple types of tumors. However, the therapeutic effect and underlying mechanism of morin in treating GC remains elusive. The study aims to explore the therapeutic effect and underlying molecular mechanisms of morin in GC. METHODS: For in vitro experiments, the proliferation inhibition of morin was measured by cell counting kit-8 assay and colony formation assay in human GC cell line MKN45, human gastric adenocarcinoma cell line AGS, and human gastric epithelial cell line GES-1; for apoptosis analysis, microscopic photography, Western blotting, ubiquitination analysis, quantitative polymerase chain reaction analysis, flow cytometry, and RNA interference technology were employed. For in vivo studies, immunohistochemistry, biomedical analysis, and Western blotting were used to assess the efficacy and safety of morin in a xenograft mouse model of GC. RESULTS: Morin significantly inhibited the proliferation of GC cells MKN45 and AGS in a dose- and time-dependent manner, but did not inhibit human gastric epithelial cells GES-1. Only the caspase inhibitor Z-VAD-FMK was able to significantly reverse the inhibition of proliferation by morin in both GC cells, suggesting that apoptosis was the main type of cell death during the treatment. Morin induced intrinsic apoptosis in a dose-dependent manner in GC cells, which mainly relied on B cell leukemia/lymphoma 2 (BCL-2) associated agonist of cell death (BAD) but not phorbol-12-myristate-13-acetate-induced protein 1. The upregulation of BAD by morin was due to blocking the ubiquitination degradation of BAD, rather than the transcription regulation and the phosphorylation of BAD. Furthermore, the combination of morin and BCL-2 inhibitor navitoclax (also known as ABT-737) produced a synergistic inhibitory effect in GC cells through amplifying apoptotic signals. In addition, morin treatment significantly suppressed the growth of GC in vivo by upregulating BAD and the subsequent activation of its downstream apoptosis pathway. CONCLUSION Morin suppressed GC by inducing apoptosis, which was mainly due to blocking the ubiquitination-based degradation of the pro-apoptotic protein BAD. The combination of morin and the BCL-2 inhibitor ABT-737 synergistically amplified apoptotic signals in GC cells, which may overcome the drug resistance of the BCL-2 inhibitor. These findings indicated that morin was a potent and promising agent for GC treatment.

ObjectiveTo investigate the clinical features and traditional Chinese medicine （TCM） syndrome distribution of treatment-naïve patients with hepatitis B virus-related primary liver cancer （HBV-PLC）， and to provide a basis for integrated traditional Chinese and Western medicine in the prevention and treatment of HBV-PLC. MethodsA retrospective analysis was performed for the clinical data of 99 treatment-naïve HBV-PLC patients who were admitted to Department of Hepatology and Infectious Diseases in The First Affiliated Hospital of Hunan University of Chinese Medicine from January 2019 to December 2024. According to whether the patient received standardized antiviral therapy （for ≥3 years）， they were divided into antiviral group and non-antiviral group， and according to the status of HBeAg， they were divided into HBeAg-positive group and HBeAg-negative group. Demographic features， laboratory test results， imaging data， and TCM syndrome data were collected， and neutrophil-to-lymphocyte ratio （NLR）， Child-Pugh score， and CNLC stage were calculated. The independent samples t-test was used for comparison of normally distributed continuous data between two groups， and the chi-square test was used for comparison of categorical data between groups. ResultsThe 99 treatment-naïve HBV-PLC patients had a mean age of 57.12±11.60 years， and the patients aged 50 — 75 years accounted for the highest proportion of 72.7%， with a male/female ratio of 5.2∶1. The patients with liver cirrhosis accounted for 81.8%， and 67.7% of the patients did not receive antiviral therapy in the past. The positive rates of HBV DNA， HBeAg， and alpha-fetoprotein were 80.8%， 18.2%， and 69.7%， respectively， and the patients with Child-Pugh class A/B disease accounted for 89.9%. Compared with the non-antiviral group， the antiviral group had a significantly smaller maximum tumor diameter （t=2.310， P=0.024）， a significantly lower HBV DNA positive rate （χ²=14.006， P<0.001）， and a significantly lower number of tumor thrombi （χ²=7.347， P=0.007）. In addition， there were significant differences between the HBeAg-negative group and the HBeAg-positive group in Child-Pugh class （χ²=6.780， P=0.034） and CNLC stage （χ²=8.746， P=0.033）. Among the 99 treatment-naïve HBV-PLC patients， 41.4% had liver depression and spleen deficiency with blood stasis， 22.2% had Qi deficiency and blood stasis syndrome， and 19.2% had damp-heat accumulation with blood stasis. ConclusionTreatment-naïve HBV-PLC patients are mainly middle-aged and elderly male individuals， and most of the patients are comorbid with liver cirrhosis. Standardized antiviral therapy can significantly reduce tumor burden and improve virologic response， with better hepatic compensation in HBeAg-negative patients， and hypoproteinemia is more common in patients with Qi deficiency and blood stasis syndrome.

Objective To obtain the monitoring measurement range of quality indicators of red blood cells,plasma and derivatives and leukocyte-reduced apheresis platelets provided by blood stations in Hebei province,explore the distribution of monitoring values and the change of monitoring level,so as to further strengthen the homogenization construction of quality control laboratories in blood stations in Hebei.Methods In 2023,the sampling data of 12 blood stations in Hebei from 2015 to 2022 were collected,scatter plots were made and the range markers were set,and the"mean±SD"line was taken as the upper limit and lower limit of the measurement range.In 2024,the monitoring values in 2023 were added,and the changes of two measurement ranges were compared to analyze the stability and overall level.Results Comparison of the measurement range from 2015 to 2022 and the measurement range from 2015 to 2023 showed that the standard deviation of the content of deleukocyte suspension of red blood cells-hemoglobin,washed erythrocyte-hemoglobin,washed erythrocyte-su-pernatant protein,cryoprecipitate coagulation factor-FⅧ,fresh frozen plasma-FⅧ,leukocyte-reduced apheresis platelets-leukocyte residue and leukocyte-reduced apheresis platelet-red blood cell concentration decreased from 8.132 to 7.993,6.252 to 6.104,0.273 to 0.267,57.506 to 56.276,0.920 to 0.892,0.653 to 0.644 and 2.653 to 2.603,respectively.The narrowing of the standard deviation range of the above items led to more concentrated monitoring values and reduced disper-sion.Comparison of the measurement range from 2015 to 2022 and the measurement range from 2015 to 2023 showed that the mean value of leukocyte residue of the deleukocyte suspension of red blood cells,hemoglobin content of the wash eryth-rocyte,protein content of supernatant of the wash erythrocyte,hemolysis rate of the wash erythrocyte,FⅧ content of the cryoprecipitate coagulation factor,plasma protein content of the fresh frozen plasma,FⅧ content of the fresh frozen plasma,platelet content of the leukocyte-reduced apheresis platelets changed from 0.362 to 0.476,44.915 to 44.861,0.280 to 0.283,0.137 to 0.142,133.989 to 133.271,60.262 to 60.208,1.301 to 1.277 and 3.036 to 3.033,respectively,and was closer to the national standard line,which reflects an increase in the number of unqualified monitoring values or values close to the national standard line in 2023.The long-term qualified rate of coagulation items was low,and no improvement has been ob-served.The stability of biochemical items has been enhanced but overall deviation has occurred,with the average value close to the national standard line.The possibility of subsequent testing failure has increased.The counting items showed no obvi-ous common characteristics.Conclusion The use of"mean±SD"in the analysis can visually display the distribution of mo-nitoring values of different items in Hebei,forming an indicator measurement range covering the past nine years.It shows the characteristics of each item,and provides reference for subsequent quality control laboratory data analysis of each blood sta-tions to takes active measures to improve the monitoring level.

MnMoO4/g-C3N4 nanocomposites were synthesized by a hydrothermal method.The MnMoO4/g-C3N4 nanocomposites were characterized by X-ray diffraction(XRD),Fourier transform infrared spectroscopy(FT-IR)and transmission electron microscopy(SEM)to analyze their morphology and structure.The MnMoO4/g-C3N4 was coated on the surface of the glassy carbon electrode(GCE)by a drop coating method and thus a electrochemical sensor for detection of metronidazole(MNZ)was successfully constructed.The electrochemical properties of the MnMoO4/g-C3N4/GCE electrode were characterized by cyclic voltammetry(CV)and differential pulse voltammetry(DPV).The effects of pH value and scanning rate on the current response were investigated.Under optimal experimental conditions,this electrochemical sensor showed a wide linear detection range(0.5-2400 μmol/L)and a low limit of detection(LOD = 1.33 nmol/L,3σ/k)for detection of MNZ.Besides,this sensor showed excellent selectivity,stability and reproducibility.The sensor was used to detect MNZ residue in eggs and milk samples,with recoveries of 97.7%-103.7%and 96.9%-102.4%,and relative standard deviations of 1.1%-2.2%,respectively,indicating that the prepared MnMoO4/g-C3N4/GCE sensor could be successfully applied to detection of MNZ in food samples.

Objective:To investigate the effects of diquat (DQ) on the expression of intestinal pyroptosis-related proteins and tight junction proteins in rats, and to analyze the role of pyroptosis in the intestinal injury of rats with acute DQ poisoning.Methods:A total of 36 Wistar male rats were randomly divided into control group, and 3 hours, 12 hours, 36 hours and 3 days exposure groups, with 6 rats in each group. Each exposure group was given 1/2 median lethal dose (LD50) of 115.5 mg/kg DQ by one-time gavage. The control group was given the same amount of normal saline by gavage. The control group was anesthetized at 3 hours after DQ gavage to take jejunal tissues; each exposure group was anesthetized at 3 hours, 12 hours, 36 hours, and 3 days after DQ gavage to take jejunal tissues, respectively. The general conditions of the rats were recorded. The pathological changes of jejunum tissue were observed by hematoxylin-eosin (HE) staining. The expression of intestinal pyroptosis-related proteins [NOD-like receptor protein 3 (NLRP3), cysteine aspartate-specific protease 1 (caspase-1), Gasdemin D (GSDMD)] in the intestinal tissues was observed by immunohistochemical staining. Western blotting was used to detect the expression of intestinal pyroptosis-related proteins and intestinal tight junction proteins (Occludin and Claudin-1).Results:Light microscopy showed that pathological changes occurred in jejunum tissue at the early stage of exposure (3 hours), and the injury was the most serious in the 12 hours exposure group, with a large number of inflammatory cells infiltrating in the tissue, and the damage was significantly reduced after 3 days exposure. Immunohistochemical results showed that NLRP3, caspase-1 and GSDMD were expressed in the jejunal mucosa of the control group and the exposure groups, and the positive cells in the control group were less expressed with light staining. The expression of the above proteins in the exposed group was increased significantly and the staining was deep. Western blotting results showed that compared with the control group, the expression of NLRP3 protein in jejunum tissues of all groups was increased, with the most significant increase in the 36 hours group (NLRP3/β-actin: 1.47±0.06 vs. 0.43±0.14, P < 0.01). Compared with the control group, the expression of GSDMD protein in the 3 hours, 12 hours and 36 hours exposure groups increased, and the expression of GSDMD protein in the 3 hours and 12 hours exposure groups increased significantly (GSDMD/β-actin: 1.04±0.40, 1.25±0.15 vs. 0.65±0.25, both P < 0.05). The expression of caspase-1 protein was increased in 36 hours exposure group compared with the control group (caspase-1/β-actin: 1.44±0.34 vs. 0.98±0.19, P > 0.05). Compared with the control group, the expression of Occludin and Claudin-1 proteins in each exposure group decreased, and the expression of Occludin proteins was significantly decreased in the 3 hours, 12 hours, and 36 hours exposure groups decreased significantly (Occludin/β-actin: 0.74±0.17, 0.91±0.20, 0.79±0.23 vs. 1.41±0.08, all P < 0.05). Although the protein expression of Claudin-1 decreased in each exposure group, the difference was not statistically significant. Conclusion:The intestinal injury caused by acute DQ poisoning may be related to the activation of pyroptosis pathway of small intestinal cells and the reduction of the density of intercellular junctions.

N1-methyladenosine(m1A)RNA methylation is critical for regulating mRNA translation;however,its role in the development,progression,and immunotherapy response of head and neck squamous cell carcinoma(HNSCC)remains largely unknown.Using Tgfbr1 and Pten conditional knockout(2cKO)mice,we found the neoplastic transformation of oral mucosa was accompanied by increased m1A modification levels.Analysis of m1A-associated genes identified TRMT61A as a key m1A writer linked to cancer progression and poor prognosis.Mechanistically,TRMT61A-mediated tRNA-m1A modification promotes MYC protein synthesis,upregulating programmed death-ligand 1(PD-L1)expression.Moreover,m1A modification levels were also elevated in tumors treated with oncolytic herpes simplex virus(oHSV),contributing to reactive PD-L1 upregulation.Therapeutic m1A inhibition sustained oHSV-induced antitumor immunity and reduced tumor growth,representing a promising strategy to alleviate resistance.These findings indicate that m1A inhibition can prevent immune escape after oHSV therapy by reducing PD-L1 expression,providing a mutually reinforcing combination immunotherapy approach.

Objective To investigate the molecular epidemiology of hypervirulent Klebsiella pneumoniae(HvKp)and its independent risk factors for infection,and to provide research basis for anti-infection treat-ment.Methods A total of 519 Klebsiella pneumoniae strains were collected from Inner Mongolia Forestry General Hospital from January 2020 to December 2022.String test was used to distinguish hypermyxoid strains(HMV-Kp)and non-HMV-KP.The rmpA,rmpA2,and iutA genes were detected by common PCR agarose gel electrophoresis to screen the HvKp strains.Multilocus sequence typing analysis was performed on 60 HvKp strains and the minimum spanning tree was drawn.Multivariate Logistic regression was used to ana-lyze the risk factors of HvKp infection.Results The positive rate of HMV-Kp was 39.69％,the positive rate of HvKp was 37.19％,and HMV-Kp accounted for 76.68％of HvKp.The detection rate of HvKp in general surgery department was the highest,and the detection rate of HvKp in pus specimens was the highest.By ST typing comparison,a total of 18 types of 60 HvKp strains were detected,ST23 type was the most common type(50.00％),followed by ST86 type(8.33％).Multivariate Logistic regression analysis showed that male,liver abscess,infection or suppuration of other tissues and organs,and use of macrolide antibiotics in the past 3 months were independent risk factors for HvKp infection(P＜0.05).Conclusion There is a strong associa-tion between HvKp and HMV-Kp strains,and ST23 type is the dominant type in this study.Male,liver ab-scess,infection or suppuration of other tissues and organs,and use of macrolide antibiotics in the past 3 months are independent risk factors for HvKp infection.
