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.

Steroid-induced avascular necrosis of femoral head(SANFH) is a bone and joint disease caused by prolonged and excessive steroid use. Its typical pathological features involve progressive circulatory disorders in the blood supply system of femoral head, leading to osteocyte apoptosis and bone tissue necrosis. As the disease progresses, it ultimately results in structural collapse and necrotic lesions of the femoral head, severely affecting patients' limb function and quality of life. Glucocorticoids mediate pathological damage through dual mechanisms, on the one hand, they disrupt the dynamic equilibrium between bone formation and resorption by suppressing osteoblast differentiation activity and activating osteoclastogenesis, on the other hand, they induce lipid metabolism disorders, inhibit angiogenesis, and impair endothelial cell function, thereby triggering microcirculatory disorders. Epimedii Folium and its active components exhibit multidimensional regulatory effects in SANFH prevention and treatment. Literature review reveals that it is rich in multiple active ingredients, primarily including total flavonoids of Epimedii Folium, icaritin, icariin, kaempferol, icariside Ⅱ, etc. These compounds exert multiple pharmacological effects(regulating bone metabolic homeostasis, modulating angiogenesis, correcting lipid metabolism disorders, and controlling cellular autophagy processes) through multiple signaling pathways, including Wnt/β-catenin, transforming growth factor(TGF)-β/bone morphogenetic protein(BMP)/Smad, mitogen-activated protein kinase(MAPK), phosphoinositide 3-kinase/protein kinase B(PI3K/Akt), osteoprotegerin/receptor activator of nuclear transcription factor-κB ligand/receptor activator of nuclear transcription factor-κB(OPG/RANKL/RANK), etc. Based on existing research findings, this paper systematically elucidates the intervention mechanisms of active components in Epimedii Folium on key pathological processes of SANFH through the above pathways. It also deeply analyzes their regulatory roles in key nodes of different signaling pathways, aiming to provide valuable references for future clinical treatment and experimental research.

Objective:
To analyze the prevalence and the related factors of comorbidity of overweight/obesity and elevated blood pressure among primary and secondary school students in Changchun, so as to provide a basis for the intervention strategies of multiple disease prevention among primary and secondary school students.
Methods:
From September to October 2023,a stratified cluster random sampling method was used to select 32 552 primary and secondary school students aged 7 to 18 from 16 counties (cities) and districts in Changchun City for physical examinations and questionnaires on behavioral patterns. The Chi-square test was used for intergroup comparison and unconditional Logistic regression model was used for analyzing related factors of comorbidity presence of overweight/obesity and elevated blood pressure among primary and secondary school students.
Results:
The detection rate of comorbidity of overweight/obesity and elevated blood pressure among primary and secondary school students was 8.7%.The detection rate of boys(10.1%) was higher than that of girls(7.3%), the detection rate was higher among students in urban areas ( 10.6 %) than that in suburban areas(5.7%); and the detection rate among vocation high school students(15.7%) was higher than that in general high school students (11.8%), junior high school students (10.2%) and primary school students (5.3%).All the differences were statistically significant (χ 2=84.67, 239.28, 468.64 ,all P <0.01).The results of the multivariate Logistic regression analysis showed that daily moderate to vigorous physical activity for 60 minutes or more ( OR =0.70) was associated with a reduced risk of comorbidity of overweight/obesity and elevated blood pressure among primary and secondary school students; boys ( OR = 1.46 ), urban residents ( OR =1.70),junior high school students( OR =1.78), general high school students ( OR =1.97), vocational high school students ( OR =2.20), and screen time without meeting the standard( OR =1.11) were associated with an increased risk of comorbidity of overweight/obesity and elevated blood pressure among primary and secondary school students(all P <0.05).
Conclusions
The comorbidity detection rate of overweight/obesity and elevated blood pressure and obesity among primary and secondary school students in Changchun is relatively high. Targeted measures should be developed to reduce the occurrence of overweight/obesity and elevated blood pressure with comorbidity of them.

ObjectiveTo investigate the therapeutic effects and potential mechanisms of Atractylodes chinensis volatile oil microemulsion in relieving depression, thus establishing a theoretical foundation and a new approach for developing it as a novel adjunctive antidepressant. MethodsSixty SD male rats were assigned into four groups: control, model (chronic unpredictable mild stress), positive drug (flupentixol hydrochloride, 1.8 mg·kg-1), and low-, medium-, high-dose (16.2, 32.4, 64.8 mg·kg-1) A. chinensis volatile oil microemulsion. The sucrose preference test, open field test, tail suspension test, and forced swimming test were conducted to measure the sucrose preference rate, total exercise distance, average speed, resting time, tail suspension time, and swimming immobility time before and after treatment. The morphology of the rat brain tissue was visualized by hematoxylin-eosin (HE) staining. The levels of 5-hydroxytryptamine (5-HT), norepinephrine (NE), and cortisol (CORT) in the hippocampal tissue were measured by enzyme-linked immunosorbent assay (ELISA). Real-time PCR was used to detect mRNA level differences of cyclic adenosine monophosphate (cAMP), protein kinase A (PKA), cyclic adenosine monophosphate response element-binding protein (CREB), brain-derived neurotrophic factor (BDNF), and tyrosine kinase B (TrkB) in the hippocampus. Western blot was employed to assess protein level variations of cAMP, PKA, CREB, BDNF, and TrkB in the same tissue samples. ResultsCompared with that in the blank group, the body mass of rats in low-, medium-, high-dose A. chinensis volatile oil emulsion groups decreased (P<0.05), indicating that the modeling was successful. Compared with the model group, medium-, high-dose A. chinensis volatile oil emulsion shortened the tail suspension time, swimming immobility time, and resting time (P<0.05, P<0.01), while increasing the sucrose preference rate, total exercise distance, and average speed (P<0.01). No significant changes were observed in the low-dose A. chinensis volatile oil emulsion group. ELISA results indicated that CORT concentrations in the hippocampal tissue of medium and high-dose A. chinensis volatile oil emulsion groups decreased (P<0.01). In the high-dose group, 5-HT and NE concentrations increased (P<0.05, P<0.01), while they had no significant changes in the low-dose group. Real-time PCR results revealed that the mRNA levels of cAMP, PKA, and CREB in the hippocampus of the medium-dose Beicangzhu volatile oil emulsion group increased (P<0.05, P<0.01), and those of cAMP, PKA, CREB, BDNF, and TrkB were upregulated in the high-dose Beicangshu volatile oil microemulsion group (P<0.01). Western blot and immunofluorescence results demonstrated that the protein levels of cAMP, PKA, and TrkB in the hippocampal tissue of the low-dose A. chinensis volatile oil microemulsion group were up-regulated (P<0.05). The medium-dose Beicangzhu volatile oil emulsion group exhibited increases in protein levels of cAMP, PKA, BDNF, and TrkB (P<0.05, P<0.01), while the high-dose group showed elevationsin protein levels of cAMP, PKA, CREB, BDNF, and TrkB (P<0.05, P<0.01). ConclusionBeicangzhu volatile oil emulsion demonstrates certain antidepressant efficacy by inhibiting CORT expression, upregulating the expression of 5-HT, NE, cAMP, PKA, CREB, BDNF, and TrkB, activating the CREB/BDNF signaling pathway to improve the cerebral protection.

To develop a novel polyamino acid-based nanohydrogel drug delivery system for dexamethasone to enhance its delivery efficiency to the inner ear. A fluorescein-labeled polyglutamic acid-based polyamino acid dexamethasone nanohydrogel was synthesized, and its gelation time was measured. The hydrogel was surgically injected into the round window niche of guinea pigs to determine its degradation time in the middle ear cavity in vivo. The safety, pharmacokinetics, and distribution patterns of dexamethasone in the inner ear were evaluated. The hydrogel exhibited a gelation time of 80 seconds in a 37℃ water bath. In vivo, the hydrogel was almost completely degraded within 7 days in the middle ear cavity of guinea pigs. Transient hearing loss was observed one day after administration, but hearing gradually returned to normal over time. No significant cytotoxicity, vestibular stimulation signs, or pathological abnormalities in spiral ganglion cells were observed. Histopathological examination revealed no significant inflammatory reactions. Pharmacokinetic analysis demonstrated sustained drug release and prolonged dexamethasone activity. Immunofluorescence staining confirmed the distribution of dexamethasone in both the cochlea and vestibular organs. The polyamino acid nanohydrogel exhibits excellent injectability and biodegradability, representing a safe and effective drug delivery system for the inner ear.

ObjectiveThis study aimed to explore the correlation between the quality of life (QOL) and different traditional Chinese medicine (TCM) syndromes in patients with myasthenia gravis (MG), identifying potential influencing factors to provide new insights for clinical interventions and improving the QOL of patients with MG. MethodsA questionnaire survey was conducted on 93 adults with MG who visited the Department of Neurology at the Affiliated Hospital of Changchun University of Chinese Medicine from March 2023 to January 2024. Statistical analysis was performed on the clinical data collected using SPSS 24.0 software. ResultsAmong the 93 patients with MG, the average score for myasthenia gravis quality of life-15 (MGQOL-15) was 17.65±6.27, and that for the 36-item short form health survey (SF-36) was (106.13±11.83) scores. The QOL was rated as good for 16 patients and moderate for 77 patients. There were no statistically significant differences in the scores of MGQOL-15, SF-36, and their individual scales by gender or education level. Age showed statistically significant differences in MGQOL-15 and the role physical (RP) scale (P<0.05), and occupational type showed significant differences in the vitality (VT) scale (P<0.01). The Myasthenia Gravis Foundation of America (MGFA) classification had statistical significance on the total SF-36 score (P<0.01), VT scale (P<0.01), role emotional (RE) scale (P<0.05), social functioning (SF) scale (P<0.05), and physical functioning (PF) scale (P<0.01). Among patients with different TCM syndromes, there were significant differences in MGQOL-15 scores (F=4.919, P<0.01). Moreover, significant differences were observed in SF-36 scores (P<0.01), VT scale (P<0.01), RE scale (P<0.05), mental health (MH) scale (P<0.01), and SF scale (P<0.05). ConclusionFactors affecting the QOL of patients with MG include age, occupational type, and clinical classification of MG. Specifically, a greater impact on the QOL of older patients is observed, while physical laborers have a poorer QOL compared to non-physical laborers. Patients classified as MGFA type Ⅱ and higher have a poorer QOL. Additionally, there is a potential correlation between the QOL and TCM syndromes, with patients presenting with spleen and kidney Qi deficiency having a lower QOL than those with spleen and stomach Qi deficiency or Qi and Yin deficiency, which is particularly evident in the VT, RE, MH, and SF scales.
