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 antidepressant mechanism of Wenyang jieyu granules （WYJYG） via the NOD-like receptor thermal protein domain associated protein 3 （NLRP3）/apoptosis-associated speck-like protein containing a CARD （ASC）/Caspase-1 pathway. METHODS A rat model of depression was established by chronic unpredictable mild stress combined with single-housing for 42 consecutive days.The experiment set up blank group， model group， MCC950 （NLRP3 inflammasome inhibitor） group （10 mg/kg）， fluoxetine group （positive control，2.08 mg/kg），low-dose WYJYG（3.78 g/kg） and high-dose WYJYG group （7.56 g/kg），with 10 rats in each group. From the 22nd day of the experiment， rats in the fluoxetine group， low-dose and high-dose WYJYG groups were intragastrically administered with the corresponding drugs and intraperitoneally injected with an equal volume of normal saline. Rats in the MCC950 group were intraperitoneally injected with MCC950 at the corresponding concentration and intragastrically administered with an equal volume of distilled water. Rats in the blank group and model group were given an equal volume of distilled water by gavage and an equal volume of normal saline by intraperitoneal injection. All interventions were performed once a day for 21 consecutive days. Behavioral tests were conducted once a week. After the last administration， the contents of ASC， ionized calcium binding adaptor molecule 1 （Iba1）， interleukin-1β （IL-1β）， and IL-18 in hippocampal tissues were detected. The protein expressions of NLRP3， cluster of differentiation 68 （CD68）， Caspase-1， B-cell lymphoma-2 （Bcl-2）， and Bcl-2-associated X protein were determined， and neuronal apoptosis was observed. RESULTS After the last administration， compared with the model group， the open-field activity time was significantly prolonged （ P ＜0.05）， and the latency to feed in a novel environment was significantly shortened （ P ＜0.05） in rats of the high-dose WYJYG group. In hippocampal tissue， the contents of ASC， Iba1， IL-1β， and IL-18， as well as the protein expression levels of NLRP3， Caspase-1， and CD68， and the positive rate of neuronal apoptosis were all significantly decreased/downregulated （ P ＜0.05）. Bcl-2 protein expression was significantly upregulated （ P ＜0.05）， and the density of neuronal apoptosis-positive cells was significantly reduced （ P ＜0.05）. CONCLUSIONS WYJYG play on antidepressant role by inhibiting the NLRP3/ASC/Caspase-1 pathway， reducing microglia-mediated neuroinflammation， and inhibiting hippocampal neurons apoptosis.

BackgroundThe professional self-concept of nurses is a crucial indicator for their personal growth， development and career planning. Previous studies have shown that work stressors during the internship period may lead to a decrease in the level of professional self-concept among nursing students. Given the existing differences in social roles between nursing students and clinical nurses， the influencing factors of professional self-concept in clinical nurses and its relationship with work stressors require further research. ObjectiveTo explore the relationship between work stressors and professional self-concept among nurses， so as to provide references for improving the level of professional self-concept of clinical nurses. MethodsFrom December 2022 to February 2023， a stratified random sampling method was employed to select 260 in-service nurses from Mianyang Hospital of Traditional Chinese Medicine as the study subjects. Chinese Nurses Stressor Scale （CNSS） and Professional Self-concept of Nurses Instrument （PSCNI） were used for assessment. Pearson correlation analysis was conducted to examine the correlation between CNSS scores and PSCNI scores of nurses. Multiple linear regression analysis was utilized to explore the factors influencing the professional self-concept of nurses. ResultsA total of 238 nurses （91.54%） completed valid questionnaires. PSCNI total score yielded a statistical difference among nurses with different marital statuses （F=8.947， P<0.05）. PSCNI total scores were significantly higher in nurses with emergency medical service experience than those without such experience （t=2.208， P<0.05）， and were significantly lower in nurses with abnormal physical examination findings in the past year than those without abnormal findings （t=-2.584， P<0.05）. Correlation analysis revealed that CNSS total score and subscale scores were negatively correlated with PSCNI total score （r=-0.275~-0.169， P<0.01）. Multiple linear regression analysis indicated that work expectation-related stressors， marital status and emergency medical service experience might be influencing factors of their professional self-concept （β=-0.350， 0.345， 0.183， P<0.01）. ConclusionNurses' work stressors are closely correlated with their professional self-concept， and high levels of stressors related to nurses' expectations may lead to a decrease in their professional self-concept levels. ［Funded by 2021 Research Project of Mianyang Municipal Health Commission （number， 202154）］

Objective:To estimate the radiation dose to caregivers and the public from 177Lu- peptide receptor radionuclide therapy (PRRT) for pediatric neuroblastoma patients and determine the duration of contact restrictions, in order to provide a reference for relevant radiation protection measures. Methods:A retrospective study was conducted by collecting data from 18 pediatric neuroblastoma patients, aged between 3 and 13 (6.72±2.72), who received 177Lu-1, 4, 7, 10-tetraazacyclododecane-1, 4, 7, 10-tetraacetic acid-D-Phe1-Tyr3-Thr8-octreotide (DOTATATE) treatment at the Nuclear Medicine Department of Shandong Cancer Hospital from June 2023 to July 2023. Absorbed dose rate in air at 0, 0.1, 0.5, 1 and 2 m from the patients was measured using a radiation-survey at 1, 4, 24, 48 and 96 h after administration. The whole-body region of interest was delined using HERMES software. Subsequently, curve regression fitting was performed using a biexponential function model. By incorporating hypothesized social contact durations, the effective doses received by family members and the public in contact with patients were estimated. Additionally, MIM software was used to outline the whole-body VOI to obtain the total volume of lesions, and the Pearson or Spearman correlation coefficient was employed to analyze the relationship between the absorbed dose rate in air and clinical indicators as well as the total volume of lesions. Results:The 177Lu-DOTATATE administration dose was (4 353.42±1 451.51) MBq. All patients were discharged from hospital 24 h after 177Lu-DOTATATE administration. At the time of discharge, patients had excreted (76.70±3.99)% of the administered activity, and the absorbed dose rate in air at 0.1, 1 and 2 m from the patients were (32.74±6.98), 3.68(3.01, 4.70) and (1.22±0.51) μSv/h, respectively. After being discharged, the radiation doses to caregivers from children aged 2-5 years and 5-13 years were (2.47±1.80) mSv and (0.88±0.47) mSv, respectively. The contact restriction duration was 2 d for nighttime sleeping with family members and 1 d for contact with other children. On the day of discharge, patients should limit their time on public transportation within 4 h and do not need to restrict private transportation. Conclusions:To ensure the effective dose kept within the safety limits stipulated by current regulations, it is necessary to implement contact restrictions for patients’ family members and the public. After implementing preventive measures, 177Lu-DOTATATE treatment is a safe radionuclide therapeutic option.

BACKGROUND: Neoadjuvant therapeutic strategies play a pivotal role in the comprehensive treatment of non-small cell lung cancer (NSCLC). However, lung squamous cell carcinoma (SCC) generally exhibits a more favorable response to neoadjuvant therapy compared with lung adenocarcinoma (ADC). The aim of this study is to elucidate how baseline cancer-associated fibroblasts (CAFs) and tumor-associated endothelial cells (TAECs) influence the differential therapeutic outcomes of neoadjuvant treatment in SCC versus ADC. METHODS: We retrospectively collected pretreatment biopsy samples from 104 patients with stage II-III NSCLC who underwent neoadjuvant chemotherapy (NAC) or neoadjuvant chemoimmunotherapy (NAIC) at Shandong Cancer Hospital between January 1, 2018 and December 31, 2023. Tissue microarrays were constructed using an automated arrayer, and multiplex immunofluorescence staining (α-SMA/CD31/CK/DAPI) was performed to identify CAFs (α-SMA+/CK-) and TAECs (CD31+/CK-). Quantitative analyses included CAFs and TAECs densities, the nearest neighbor distance (NND) between CAFs and TAECs, and their spatial proximity (30 μm). Differences in major pathological response (MPR) between groups, defined as residual viable tumor cells ≤10% in resected specimens after neoadjuvant therapy, were assessed using the χ² test. The Mann-Whitney U test was applied to analyze intergroup differences in quantitative indicators, and receiver operating characteristic (ROC) curve analysis was conducted to evaluate the predictive performance of immune-related markers for MPR in the NAIC cohort. RESULTS: Among the 104 NSCLC patients who received neoadjuvant therapy, 35 underwent NAIC and 69 received NAC. Overall, patients with SCC were more likely to achieve MPR compared with those with ADC (50.0% vs 22.4%, P=0.006). This trend persisted in the NAIC subgroup (72.7% vs 30.8%, P=0.038), whereas no significant difference in MPR rates was observed between SCC and ADC in the NAC subgroup. At baseline, prior to NAIC or NAC, programmed cell death ligand 1 (PD-L1)/programmed cell death 1 (PD-1) expression, CAFs and TAECs densities, CAFs-TAECs NND, and CAFs-TAECs proximity (30 μm) showed no significant differences between SCC and ADC. In patients with SCC receiving NAIC, baseline PD-L1/PD-1 expression, CAFs density, and TAECs density showed not significant differences between MPR and NMPR groups. However, the CAFs-TAECs distance was significantly greater in the MPR group (NND: 31.2 vs 24.7 μm, P=0.038), and the number of TAECs within 30 μm of CAFs was significantly lower (proximity: 1.1 vs 3.6, P=0.038). Univariate Cox regression analysis indicated that low TAECs density was associated with MPR following NAIC (OR=36.00, 95%CI: 2.68-1486.88, P=0.019). Furthermore, ROC analysis demonstrated that baseline CAFs-TAECs NND and proximity (30 μm) exhibited strong predictive performance for MPR in SCC patients treated with NAIC, with an area under the curve (AUC) of 0.893, sensitivity of 0.857, and specificity of 1.000. CONCLUSIONS CAFs are more spatially distant from TAECs and more prone to MPR after NAIC in SCC, which may be related to the reduced interaction of CAFs with TAECs and reduced tumor-associated angiogenesis.

Objective:The impact of bystander CD8 + T cells (CD8 + Tbys) within the tumor microenvironment on the prognosis of early-stage non-small cell lung cancer (NSCLC) remains unclear, particularly concerning their infiltration differences at the invasive margin (IM) and tumor center (TC). Methods:We retrospectively collected postoperative specimens from 173 patients with primary early-stage NSCLC who underwent radical surgery at the Affiliated Tumor Hospital of Shandong First Medical University from 2014 to 2018. Tissue microarrays encompassing IM and TC regions were prepared and subjected to multicolor immunofluorescence staining (CK/CD8/CD103/DAPI). Image processing and phenotype recognition (CD8 + T cells, CK -CD8 +; CD8 + T bys, CK -CD8 +CD103 -) were performed using inFrom software, and automatic quantitative cell density analysis was conducted using R language. Differences in CD8 + T and CD8 + T bys densities at IM and TC were analyzed using the Mann-Whitney U test. The relationship between CD8 + T, CD8 + T bys and clinicopathological features was examined using the Kruskal-Wallis H test. The impact of CD8 + T and CD8 + T bys on recurrence-free survival (RFS) was evaluated using Kaplan-Meier, log-rank, and Cox proportional hazards models. Results:A total of 173 patients with stage ⅠA-ⅡA NSCLC were included, with a recurrence rate of 26.6% (46/173) and a median RFS of 62.3 months (range: 44.7-71.9 months). CD8 + T and CD8 + T bys densities (1/1 000) were significantly higher in the IM region than in the TC region [70(32, 155) vs. 37(18, 88), P＜0.001; 25(11, 46) vs. 18(7, 34), P=0.002]. No significant association was found between CD8 + T, CD8 + T bys and age, gender, smoking history, histological type, or pathological stage (all P＞0.05). Patients with low-density IM CD8 + T cells had lower RFS compared to those with high-density IM CD8 + T cells ( P=0.021; median RFS not reached), Further analysis revealed that patients with low-density IM CD8 + T bys cell had lower RFS compared to those with high-density IM CD8 + T bys ( P=0.047; median RFS not reached), and low-density IM CD8 + T cell was an independent risk factor for postoperative recurrence ( HR=1.836, 95% CI:1.007-3.347, P=0.048). Joint analysis of IM and TC revealed that patients with low IM CD8 + T bys and high TC CD8 + T bys had significantly lower RFS compared to the other three groups ( P=0.006), and this combination was an independent risk factor for postoperative recurrence in early-stage NSCLC ( HR=2.090, 95% CI:1.162-3.760, P=0.014). Conclusions:The spatial distribution of bystander CD8 + T cells within the primary tumor influences the prognosis of patients with early-stage NSCLC. Patients with low-density IM CD8 + T bys and high-density TC CD8 + T bys are more prone to recurrence after radical surgery.

Objective:To analyze the relationship between folate and thyroid antibody in early pregnancy and adverse pregnancy outcome in pregnant women with hypothyroidism during pregnancy.Methods:The data of 97 pregnant women with hypothyroidism from Jul. 2020 to Mar. 2023 in the Obstetrics Department of Liaocheng Second People’s Hospital were retrospectively analyzed. The levels of folate, thyroglobulin antibody (TGAb) and thyroid peroxidase antibody (TPOAb) were detected in the first trimester. According to whether adverse pregnancy outcome occurred in pregnant women with hypothyroidism during pregnancy, they were divided into occurrence group and non-occurrence group. The clinical data of the occurrence group and the non-occurrence group were compared. Logistic regression was used to analyze the influencing factors of adverse pregnancy outcomes in pregnant women with hypothyroidism during pregnancy, and receiver operating characteristic (ROC) curve was drawn to analyze the predictive value of folic acid, TGAb, TPOAb and their combination on adverse pregnancy outcomes in pregnant women with hypothyroidism during pregnancy.Results:Among 97 pregnant women, the incidence of adverse pregnancy outcome was 14.43% (14/97) .The folate level in the occurrence group was lower than non-occurrence group ( P<0.05) , and the TGAb and TPOAb levels in the occurrence group were higher than non-occurrence group ( P<0.05) . The occurrence group with alanine aminotransferase (ALT) , glutamine transpeptidase (GGT) and aspartate aminotransferase (AST) were all higher than non-occurrence group ( P<0.05) .The folate, TGAb, and TPOAb levels were factors influencing adverse pregnancy outcomes in pregnant women with hypothyroidism ( P<0.05) . The area under the curve (AUC) values of folate, TGAb, TPOAb and their combined prediction of adverse pregnancy outcomes in pregnant women with hypothyroidism during pregnancy were 0.804, 0.843, 0.799, 0.909 ( P<0.05) , while the combined three with AUC values were higher ( P<0.05) . Conclusion:The folate, TGAb and TPOAb levels in early pregnancy can be used to evaluate adverse pregnancy outcomes in hypothyroidism pregnant women, and the combination of the three has a higher evaluation value.

Age-related macular degeneration(AMD)is one of the leading causes of blindness in the elderly.Wet AMD(nAMD)accounts for more than 90％of AMD-related vision loss.Pathologically,nAMD is defined by choroidal neovascu-larization(CNV)and chronic retinal inflammation driven by oxidative stress,complement activation,pro-inflammatory cy-tokines,and overexpression of vascular endothelial growth factor(VEGF).Yet anti-VEGF monotherapy often falls short.The nuclear factor kappa-B(NF-κB)signaling cascade,acting through both canonical and non-canonical pathways,or-chestrates the expression of genes governing immunity,inflammation,apoptosis,and angiogenesis.In nAMD,oxidative stress and complement fragments ignite NF-κB,unleashing a repertoire of pro-inflammatory and pro-angiogenic mediators that fuel CNV.Pharmacologic or genetic suppression of NF-κB dampens both inflammation and neovascularization,attenua-ting experimental CNV.Thus,dissecting the molecular machinery of NF-κB signaling in nAMD may uncover novel combina-tion strategies that enhance therapeutic efficacy and curb anti-VEGF resistance.
