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.

Purpose: This study aimed to evaluate the safety and efficacy of gemcitabine and cisplatin (GP) regimen in combination with immune checkpoint inhibitor sintilimab as neoadjuvant therapy for muscle-invasive bladder cancer (MIBC) patients and the feasibility of the following selective bladder sparing surgery. Materials and Methods: Patients with histopathologically confirmed urothelial carcinoma without distant metastases (T2-4a, N ≤ 1, M0, American Joint Committee of Cancer 8th) and with adequate organ function will be enrolled. The therapeutic regimen was sintilimab 200 mg once on day 8, gemcitabine 1,000 mg/m2 and cisplatin 35 mg/m2 once on days 1 and 8, every 21 days for four cycles. The primary endpoint was pathologic complete response (pCR, pT0N0) rate. The secondary end points were ypT < 2 rate, R0 resection rate, event-free survival, and safety. Results: From May 4, 2020, to May 20, 2023, 55 patients were enrolled. Forty-six patients were evaluated for efficacy. Among the 42 patients who underwent surgery, 16 patients (38.0%) achieved pCR. Thirty-three patients (78.6%) achieved pT < 2. With a median follow-up of 15.7 months, the 1-year event-free survival was 91.3%. Notwithstanding the poor pathological baseline characteristic of a high T3-T4a proportion (39.1%), a promising bladder preservation (including 22 patients transurethral resection of bladder tumor, 5 patients partial cystectomy, and 4 surveillances) rate was achieved (67.4%). The most common grade ≥ 3 treatment-related adverse events was neutropenia (n=15, 27.3%), which was related to chemotherapy. There were no grade 3 immune-related adverse events. Conclusion Neoadjuvant GP plus sintilimab is a promising regimen for MIBC patients, with relatively high pT < 2 rate and triggering the emerging roles for the multi-disciplinary team decision-making for bladder sparing surgery.

Objective To investigate the effects and mechanisms of combined prescriptions of essential oils from five traditional Chinese medicinal herbs,namely peppermint,turmeric,ginger,Tibetan fennel,and cumin,on symptoms related to functional abdominal pain syndrome(FAPS).Methods Gas chromatography-mass spectrometry(GC-MS)was employed to analyze the chemical constituents of five essential oils,while network pharmacology was utilized to predict the key targets and signaling pathways associated with these essential oils in alleviating functional abdominal pain syndrome.A formula design methodology centered on these core targets and signaling pathways was developed for creating new prescriptions.Molecular docking technology was conducted to predict its the underlying mechanisms.Subsequently,animal experiments were performed to assess pharmacological activity,including hot plate tests and acetic acid-induced writhing assays to validate the analgesic effects of the newly formulated prescription,as well as xylene-induced ear swelling tests to evaluate its anti-inflammatory properties.The impact of the essential oil formulation on intestinal peristaltic function was examined through intestinal propulsion experiments.Additionally,enzyme-linked immunosorbent assay(ELISA)methods were employed to measure levels of serotonin(5-HT),prostaglandin E2(PGE2),and gamma-aminobutyric acid(GABA)in brain tissue.Western blot analysis was conducted to determine protein expression levels of TPH1 and SERT in the intestine,along with TPH2 and SERT in the brain.Results The main chemical components in five essential oils were identified and screened(peppermint:12,turmeric:8,ginger:14,cumin:2,fennel:6).Based on the network pharmacology analysis,four new essential oil prescriptions were successfully designed according to the complementary relationship between the five essential oils in improving functional abdominal pain syndrome at the target level,including 4 new prescription named Prescription A,B,C and D,these four prescriptions were all based on ginger and turmeric essential oils,with other essential oils serving as supplements or enhancements.The results of animal experiments showed that Prescription D could significantly reduce the writhe frequency of mice(P<0.05),all the four groups could significantly prolong the pain threshold of mice(P<0.05),and Prescription C had a significant effect on reducing the degree of ear swelling(P<0.05).The prescription of essential oil did not significantly affect the function of peristalsis and the speed of propulsion.The levels of 5-HT and PGE2 in the brain tissue were significantly inhibited(P<0.05),and the level of GABA was significantly increased(P<0.05).Prescription C could reduce the expression of TPH1 in the intestinal tissue(P<0.05),Prescription A,C and D could reduce the expression of TPH2,and all groups had a tendency to increase the expression of SERT in the brain tissue.Conclusion In summary,the therapeutic effects of the four novel prescriptions composed of the five essential oils demonstrated potential in improving symptoms related to FAPS,the mechanism might be through modulating abnormalities in the brain-gut axis system.

Aim To clarify the mechanism by which Qishen Yixin Granules improved microcirculation vas-cular endothelial dysfunction(VED)in mice,through activating the Nrf2/HO-1 signaling pathway to regulate oxidative stress.Methods C57 mice were randomly divided into six groups:blank group,model group,pos-itive drug group,and low-,medium-,and high-dose groups of Qishen Yixin Granules.The VED model was established by long-term infusion of Ang Ⅱ combined with a high-fat diet.Each treatment group received the corresponding drug intervention.After four weeks of drug intervention,cardiac function was assessed by echocardiography.Carstairs staining was used to ob-serve the formation of microthrombi in myocardial tis-sue.The micro vascular ischemia was evaluated by Hei-denhain staining.The ultrastructure of endothelial cells was observed by electron microscopy.The levels of EMPs,ROS,NO,ET-1,TF,TM,VWF,and TXA2 in serum were measured by ELISA.The expression levels of MDA,SOD,and GSH-Px in mouse heart tissue were determined by chemical methods.Cardiac microvascu-lar density and the expression of Nrf2,Keap1,and HO-1 proteins were detected by Immunohistochemical stai-ning.The protein expressions of Keap1,cytoplasmic Nrf2,nuclear Nrf2,and HO-1 in myocardial tissue were detected by Western blot.Results Qishen Yixin Granules could effectively improve the cardiac function of mice,alleviate the damage of endothelial cells and endothelial function.They could up-regulate serum NO levels and the activities of antioxidant enzymes SOD and GSH-Px,while down-regulating the expression of ROS and vascular inflammatory injury factors such as ET-1,VWF,TXA2,TF,TM,and EMPs.Qishen Yixin Granules also increased the positive counts of CD34,Nrf2,and HO-1,as well as microvessel density.Fur-thermore,they inhibited the expression of MDA,Keap1,and cytoplasmic Nrf2 protein in myocardial tis-sue,while increasing the expression of nuclear proteins HO-1 and Nrf2.Conclusions Qishen Yixin Granules may inhibit oxidative stress and inflammatory response by regulating the Nrf2/HO-1 signaling pathway,thereby improving vascular endothelial damage and cardiac function in VED mice.

Objective The aim of this study was to analyze the incidence trend and age-specific characteristics of esophage-al cancer in cancer registration areas of Gansu Province from 2010 to 2021,and predict the incidence of esophageal cancer from 2022 to 2030.Methods Based on the incidence data of esophageal cancer in 15 cancer registries in Gansu Province from 2010 to 2021,the incidence was calculated by age,sex,urban and rural areas.The age-standardized incidence by Chinese standard population(ASIRC)was standardized using the 2000 Chinese standard population.Joinpoint regression model was used to analyze the change trend of esophageal cancer incidence,and the average annual percentage change(AAPC)was calculated to quantify the overall rate of change.A birth cohort model was constructed to analyze incidence trend of different birth groups from 1930 to 2021,and the Bayesian age-period-cohort(BAPC)model was used to predict incidence.Results From 2010 to 2021,the ASIRC of esophageal cancer in Gansu Province showed a significant downward trend(AAPC=-14.47％,95％CI:-18.72％--9.99％,P＜0.001).The ASIRC in men decreased at an annual rate of 13.02％(AAPC=-13.02％,95％CI:-17.28％--8.54％,P＜0.001),the incidence of esophage-al cancer in women at a rate of 15.80％per year(AAPC=-15.80％,95％CI:-20.69％--10.61％,P＜0.001).The ASIRC of e-sophageal cancer in urban areas decreased at an annual rate of 15.32％(AAPC=-15.32％,95％CI:-21.04％--9.18％,P＜0.001);ASIRC of esophageal cancer in rural areas decreased at a rate of 5.33％per year(AAPC=-5.33％,95％CI:-8.94％--1.58％,P＜0.001).From 2010 to 2021,the incidence of esophageal cancer in all age groups showed a significant downward trend(AAPC:-19.59％to-9.18％).The birth cohort analysis revealed that the incidence of esophageal cancer in people over 40 years old in the province,men,women,urban and rural areas showed a downward trend with increase of birth years.BAPC model predicted that that the ASIRC of esophageal cancer for the total province population,men and women would decrease from 6.47/100,000,10.02/100,000,and 2.95/100,000 in 2021 to 1.31/100,000,1.72/100,000,and 0.91/100,000 in 2030,respectively.Conclu-sions The incidence of esophageal cancer in Gansu Province showed a downward trend from 2010 to 2021,but men and rural areas were still the focus of high incidence.The prediction indicates that the incidence of esophageal cancer in Gansu Province will further decline by 2030,suggesting that the prevention and control measures have achieved results;however,it is still necessary to strengthen the intervention and long-term monitoring of high-risk groups.

Objective:To conduct a systematic review and Meta-analysis of unavoidable pressure injuries (uPI) to provide evidence-based guidance for establishing standardized intervention protocols.Methods:Cross-sectional and cohort studies on uPI were systematically retrieved from PubMed, Web of Science, Embase, Cochrane Library, China National Knowledge Infrastructure, Wanfang, and China Biology Medicine disc databases up to February 5, 2024. Two researchers independently screened the literature, extracted data, and assessed the risk of bias in the included studies. Meta-analysis was performed using R4.3.2 software.Results:A total of 9 studies involving 10 research items were included. The Meta-analysis showed that the proportion of uPI was 42.92%. Subgroup analysis revealed that the proportions of uPI in acute care hospitals, intensive care units, and long-term care facilities were 53.14%, 33.56%, and 40.97%, respectively. The proportions in North America and Europe were 40.26% and 44.99%, respectively. The proportions of uPI in studies published between 2010-2015, 2016-2020, and 2021-2024 were 63.25%, 37.00%, and 40.61%, respectively. The proportions of uPI assessed using the Pressure Ulcer Prevention Inventory, National Pressure Ulcer Advisory Panel definition, empirical judgment, NHS definition, and end-stage pressure injury definition were 40.38%, 26.17%, 40.00%, 62.07%, and 51.32%, respectively.Conclusions:The incidence of uPI is high, with significant differences across healthcare settings, continents, years, and assessment criteria. A universal definition of uPI should be established, along with unified assessment standards, to optimize uPI care strategies and provide references for standardized prevention and intervention.
