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 risk factors for cardiac valve calcification (CVC) in maintenance hemodialysis (MHD) patients and evaluate its impact on cardiovascular events and mortality. Methods Retrospective selection of 223 patients with MHD admitted to the Department of Nephrology of Jinshan Hospital, Fudan University from June 30, 2019 to June 30, 2024, and enrollment completed within one week of June 30, 2019. Patients were divided into CVC and non-CVC groups. Baseline data and 5-year follow-up data were collected. The binary logistic regression analysis was performed to explore the risk factors for CVC. Kaplan-Meier survival curve was used to analyze the survival rate of patients. Cox proportional hazard regression model was applied to evaluate the impact of CVC on the survival rates of MHD patients. Results Totally, 223 MHD patients with an average age of (58.4±13.5) years and an average dialysis duration of (64.0±55.4) months were involved. Among them, 136(61.0%) were males, 117(52.5%) were complicated with CVC. Age, dialysis duration, diabetic kidney disease (DKD), the serum corrected total calcium and phosphate, intact parathyroid hormone (iPTH), high-sensitive C-reactive protein (hsCRP), and homocysteine (Hcy) were independent related factors for CVC (P＜0.05). Both all-cause mortality (46.6% vs 28.7%) and cardiovascular mortality (33.3% vs 16.0%) were significantly higher in the CVC group than those in the non-CVC group (P＜0.01). Conclusions Age, dialysis duration, the primary disease, calcium and phosphate, and inflammation- and nutrition-related serum indicators are associated with CVC in MHD patients. CVC significantly increases mortality risk of MHD patients.

Intervention in chronically activated microglia-mediated neuroinflammation is a novel approach to treat Alzheimer's disease (AD). The low permeability of the blood‒brain barrier (BBB) and non-selective distribution in the brain severely restrict AD drugs' disease-modifying efficacy. Here, an immunosuppressant TREM2-lowing antisense oligonucleotides (ASOs) and resveratrol co-loaded cationic liposome is developed as an immune reprogramming nanomodulator modified by acid-cleavable BBB-targeting peptide and microglia-targeting peptide (Res@TcMNP/ASO) for AD management. Res@TcMNP/ASO can enter brain endothelial cells via D-T7 peptides. Then D-T7 undergoes an acid-responsive cleavage, facilitating the escape of Res@MNP/ASO from endo/lysosomes to cross the BBB. The detached Res@MNP/ASO specifically targets M1-phenotype microglia via exposed MG1 peptides to prompt the simultaneous delivery of two drugs into activated microglia. This nanomodulator can not only restore the immune function of microglia through TREM2-lowing ASO but also mitigate the immune stimulation to microglia caused by reactive oxygen species (ROS) through resveratrol, thereby synergistically inhibiting the chronic activation of microglia to alleviate neuroinflammation in AD. Our results indicate that this combination treatment can achieve significant behavioral and cognitive improvements in late APP/PS1 mice.

Objective To understand the incidence of nutritional risk in IBD patients in Kunming City,and to analyze the influencing factors.Methods A total of 707 IBD patients who were hospitalized in the First Affiliated Hospital of Kunming Medical University from September 2016 to May 2024 were retrospectively enrolled.Patient general information,disease-related data,and laboratory examination results were collected.Nutritional risk screening was performed using the NRS2002 scale,with subjects divided into nutritional risk and no-nutritional risk groups.Among Crohn's disease(CD)patients,110 were in the nutritional risk group and 85 in the no nutritional risk group.For ulcerative colitis(UC)patients,146 were in the nutritional risk group and 366 in the no nutritional risk group.Statistical analysis was conducted on the collected data.Results The incidence of nutritional risk in IBD patients was 36.21%,with 56.41%for CD and 28.52%for UC.Statistical analysis showed that for CD patients,sleep,BMI,disease diagnosis age,and disease activity were influencing factors of nutritional risk(P<0.05).For UC patients,influencing factors were BMI,disease activity,albumin(ALB),and erythrocyte sedimentation rate(ESR)(P<0.05).Conclusion IBD patients have a high nutritional risk,with CD patients being more severely affected.The influencing factors of nutritional risk are complex.Medical personnel should conduct early nutritional risk screening for IBD patients to avoid adverse outcomes due to nutritional issues.

【Objective】 To investigate the anemia status of infants and toddlers aged 6 - 24 months in Linxia Hui Autonomous Prefecture, Gansu Province, and to comprehensively evaluate the differences in feeding behaviors between anaemic and normal children through the infant and child feeding index (ICFI) and feeding knowledge scores, so as to provide reference for the guidance of infants and young children feeding in ethnic minority areas and the promotion of children′s growth and development. 【Methods】 Taking infants and young children aged 6 - 24 months in Linxia Prefecture as the study subjects, a multi-stage random sampling method was used to select children who met the requirements from 5 townships and 5 villages in 7 counties in 2019 and 2020.Periphral blood samples were collected to test the level of hemoglobin, so as to determine the anemia status.Meanwhile, physical examination was performed and a questionnaire survey of guardians was conducted to analyze the association betweenanaemia and feeding patterns 【Results】 A total of 3 901 infants and children were included in this study, of whom 729 (18.70%) were anaemic, with a mean ICFI score of 12.56±2.70 and a mean feeding knowledge score of 1.97±1.01.There was no statistically significant association of low feeding knowledge score and low ICFI with anaemia after adjusting for confounders (P>0.05), Unqualified meat addition in ICFI was a risk factor for anaemia (OR=1.355, P=0.042), while non-bottle feeding in the past 24 hours (OR=0.762, P=0.021), and breastfeeding in the past 24 hours of infants and toddlers aged 12 - 24 months (OR=0.228, P=0.018) were protective factor for anemia in infants and toddlers aged 12 - 24 months. 【Conclusions】 The average prevalence of anemia in infants and toddlers aged 6 - 24 months in Linxia Hui Autonomous Prefecture of Gansu Province is high, but the level of infant feeding and the level of feeding knowledge of caregivers are low.Early adherence to breastfeeding, timely addition of supplementary food, and more comsumpution of meat for children are conducive to preventing anemia.

Objective To analyze the risk factors for survival in patients with hematological malignancies after hematopoietic stem cell transplantation (HSCT), to establish a risk prediction and survival prediction model, and to provide a reference for clinical diagnosis and treatment. Methods A total of 237 patients with malignant hematological diseases who underwent HSCT at West China Hospital of Sichuan University from January 2017 to April 2019 were selected as the study subjects. The survival of all patients after HSCT was statistically analyzed. The influencing factors of survival were analyzed by multivariate regression analysis, and the prediction model was constructed. Results A total of 237 patients with hematological malignancies were included in this study. After 3 years of follow-up, 85 patients died, with a mortality rate of 35.86%. Multivariate logistic analysis showed that diabetes mellitus (OR=4.358, P=0.007), infection (OR=3.522, P=0.000), neutropenia time >7d (OR=2.734, P=0.009), incomplete HLA matching (OR=5.688, P=0.000), cGVHD (OR=2.593, P=0.007) and HCT-CI (OR=6.701, P=0.000) were independent risk factors affecting the survival of patients with hematological malignancies after HSCT (P<0.05). The risk prediction model for survival was P=1/(1 + e ^{(3.192 + 01.259 + 1.472 ×(diabetes mellitus) + 1.259×(infection) + 1.006 ×(neutropenia time) + 1.738 ×(HLA matching) + 0.953 ×(cGVHD) + 1.902 ×(HCT-CI)}), Hosmer-Lemeshow χ²=6.692, P=0.462. AUC and 95%CI of the model for predicting survival were 0.836 and 0.783-0.888, showing good fit and predictive efficiency. Conclusion Diabetes mellitus, infection, neutropenia time >7d, incomplete HLA matching, cGVHD and HCT-CI are all high-risk factors of survival in patients with malignant hematologic disease after HSCT. Clinically, attentions should be paid to these patients and intervention measures should be taken to improve their survival after HSCT.

Gastrointestinal motility disorder is an important cause of digestive system diseases. Patients often suffer from nausea， vomiting， gastric retention， gastroparesis， constipation， and many other symptoms， and their quality of life is seriously reduced. Prokinetic agents are routinely used in clinical practice， but their long-term use is prone to problems such as reduced efficacy and increased adverse reactions. Since the incidence of gastrointestinal diseases has continued to rise globally in recent years， there is an urgent need for clinical development of safe and effective treatment strategies. Aurantii Fructus， a traditional Chinese medicine， has the effect of smoothing Qi and eliminating distention， and it has been used to treat gastrointestinal diseases for thousands of years. In modern clinical practice， it is mainly used for the treatment and auxiliary treatment of various gastrointestinal diseases such as functional dyspepsia， functional constipation， and irritable bowel syndrome. The efficacy is remarkable， and no adverse reactions have been reported at conventional doses. Therefore， it can greatly improve the symptoms of patients with gastrointestinal diseases and improve their quality of life. Modern research has revealed that there are many active components in Aurantii Fructus， among which flavonoids have the highest content and the most types. Flavonoids are the main active components in Aurantii Fructus to regulate gastrointestinal motility. Aurantii Fructus and its active components can affect gastrointestinal hormones， neural pathways， Cajal mesenchymal cells， and other multiple mechanisms. They can adjust gastrointestinal motility and correct gastrointestinal motility disorders， showing potential application value in the treatment of gastrointestinal motility disorders. However， a comprehensive analysis of Aurantii Fructus in this aspect is still lacking. This study summarized the pharmacological activities of active components of Aurantii Fructus extract and its flavonoids， volatile oils， alkaloids， and coumarin on the regulation of gastrointestinal motility and explored the latest research progress on its mechanism. Finally， the adverse reactions of Aurantii Fructus were summarized. It aims to provide a scientific basis for the research and clinical application of Aurantii Fructus and its active components in the regulation of gastrointestinal motility.

Objective To investigate the nutritional status in patients with aplastic anemia (AA), and to analyze the influencing factors. Methods A retrospective analysis was performed on the clinical data of 152 patients with AA admitted to West China Hospital between March 2019 and March 2022. The nutritional status of all patients was screened by Nutritional Risk Screening 2002 (NRS2002). According to the screening criteria, the patients were divided into control group (46 cases, total NRS2002 score <3 points) and malnutrition risk group (106 cases, total NRS2002 score ≥3 points). The body mass index (BMI), disease grading [severe AA (SAA), non-severe AA (NSAA)], levels of hemoglobin (Hb), serum albumin (Alb), serum ferritin (SF), total protein (TP), folic acid (FA), vitamin B12 (VB12), serum iron (SI), unsaturated iron binding capacity (UIBC) and transferrin saturation (TSAT) were recorded and compared between the two groups. The risk factors of malnutrition were analyzed by logistic regression analysis, and levels of the related influencing factors were compared. The association between nutritional risk and prognosis in patients with AA was analyzed. Results Among the 152 patients with AA, 69.74% of them were at risk of malnutrition. There was no significant difference in the BMI, TP, FA and VB12 between the malnutrition risk group and the control group (P>0.05). The proportion of SAA cases in the malnutrition risk group was significantly higher than that in the control group. The levels of Alb and UIBC in the malnutrition risk group were significantly lower than those in the control group, while the levels of SF, SI and TSAT were higher than those in the control group. In addition, the levels of SF, SI and TSAT in SAA patients were higher than those in NSAA group (P<0.05). Logistic regression analysis showed that high levels of SF, SI and TSAT, and high proportion of SAA cases were risk factors of malnutrition in AA patients (P<0.05). The incidence of adverse prognosis in the malnutrition risk group was significantly higher than that in the control group, and the difference was statistically significant (P < 0.05). Conclusion Patients with AA have a higher risk of malnutrition, and high levels of SF, SI and TSAT are risk factors for malnutrition. The greater the risk of malnutrition, the more severe the poor prognosis.

Purpose To evaluate the value of shear wave elastic imaging of liver and spleen in predicting high risk esophageal and gastric varices in cirrhosis.Materials and Methods Sixty-four patients with cirrhosis in the First Hospital of Lanzhou University from November 2019 to April 2022 were enrolled prospectively,and underwent gastroscopy,elastography and serological examination.According to gastroscopy,patients were divided into high-risk varices(HRV,30 cases)and non-HRV group(34 cases),the differences of each clinical index and shear wave elastic imaging parameter between the groups were compared.The diagnostic efficacy of liver and spleen stiffness measurement for HRV was analyzed.And the diagnostic models were established for exploring the diagnostic effectiveness of different models with respect to excluding HRV in compensated liver cirrhosis.Results There were significant differences in platelet[(74±24)×109/L vs.(124±50)×109/L],liver stiffness[(16.1±5.6)kPa vs.(13.6±5.5)kPa]and spleen stiffness[(41.7±8.9)kPa vs.(28.1±8.6)kPa]between HRV and non-HRV groups(t/Z/χ2=5.136,-1.832,-6.206,all P<0.05).The areas under the curve of liver stiffness and spleen stiffness for predicting HRV were 0.660 and 0.858,respectively.The Baveno Ⅵ combined with the spleen stiffness model had the best performance(30.0％)for excluding HRV.Conclusion The measurement of liver and spleen stiffness by shear wave elastography has great diagnostic value for predicting HRV in cirrhosis,and spleen stiffness is better than liver stiffness.

Objective:To explore the effect of cathepsin L (CTSL) inhibitor on apoptosis of retinal pigment epithelial (RPE) cells and mitochondrial oxidative stress.Methods:RPE cells were cultured in vitro and divided into control group, hydrogen peroxide (H 2O 2) group, and H 2O 2+CTSL inhibitor group. The cells of H 2O 2 group and H 2O 2+CTSL inhibitor group were incubated in the medium containing 400 μmol/L H 2O 2 for 24 hours and 10 μmol/L CTSL inhibitor was added in H 2O 2+CTSL inhibitor group at the same time. The cells of normal group were routinely cultured cells. The follow-up experiment was carried out 24 hours after modeling. The rate of apoptosis was detected by flow cytometry. The expression of CTSL was detected by immunofluorescence staining, Western blot and real time-polymerase chain reaction. The level of mitochondrial super oxide was detected by MitoSOX fluorescent probe, and the mitochondrial structure was observed after MitoTracker staining, the average area, form factors, and branch of mitochondria were quantitatively analyzed. The two groups were compared using two-tailed Student t test, while numerous groups were compared using one-way ANOVA. Results:Compared with control group, the rate of apoptosis in H 2O 2 group was significantly higher ( t=3.307, P=0.029 7), the expression level of CTSL was significantly increased ( t=19.950, 6.916, 14.220; P<0.05). Compared with H 2O 2 group, the expression level of CTSL, the rate of apoptosis and the mitochondrial ROS level in H 2O 2+CTSL inhibitor group were significantly lower ( t=11.940, 4.718, 16.680; P<0.05). The mitochondria of H 2O 2+CTSL inhibitor group were elongated, oval-shaped or rod-shaped, while the mitochondria of H 2O 2 group lost their continuous contour shape and complete structure. The differences of the average area, form factors, and brach of mitochondria among 4 groups were statistically significant ( F=251.700, 34.010, 60.500; P<0.000 1). Conclusions:H 2O 2 can significantly induce apoptosis in RPE cells and increase CTSL expression. CTSL inhibitor can inhibit the H 2O 2-induced apoptosis of RPE cells, lower the mitochondrial super oxide level, and successfully repair the mitochondrial structure.
