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.

ObjectiveTo establish a mouse model of rheumatoid arthritis with interstitial lung disease （RA-ILD） in DBA/1 mice using Porphyromonas gingivalis （Pg） infection combined with collagen-induced arthritis （CIA）， and to comprehensively evaluate pathological characteristics in joints， lungs， and serum. MethodsForty DBA/1 mice were randomly divided into four groups， i.e.， Control， Pg infection （Pg）， CIA， and Pg infection combined with CIA （Pg+CIA）， with 10 mice in each group. Arthritis clinical symptoms were evaluated by recording arthritis incidence and clinical scores. Micro-CT scanning was used to assess knee joint pathology. Histopathological changes and collagen deposition in knee joints and lung tissues were analyzed using hematoxylin-eosin （HE） and Masson staining. Immunohistochemistry was performed to detect protein expression of α-smooth muscle actin （α-SMA）， typeⅠ collagen （ColⅠ）， and fibronectin （FN） in lung tissues. Real-time quantitative polymerase chain reaction（Real-time PCR）was used to measure mRNA expression levels of α-SMA， ColⅠ， FN， tumor necrosis factor-α （TNF-α）， interleukin-6 （IL-6）， and IL-1β in lung tissues. Enzyme-linked immunosorbent assay （ELISA） was used to detect serum levels of Pg， cyclic citrullinated peptide （CCP）， and immunoglobulin G （IgG）. ResultsJoint lesions： The CIA and Pg+CIA groups showed 100% arthritis incidence， with evident joint redness， swelling， and deformity. The number of affected limbs was 27 and 28， and clinical scores were 68 and 70， respectively. No obvious clinical symptoms were observed in the Pg group. Histopathological and imaging analyses showed severe joint lesions in the CIA and Pg+CIA groups， with significantly increased histopathological scores， bone mineral density， bone volume fraction， trabecular thickness， and trabecular number compared to the Control group （P<0.01）. No obvious joint pathology was observed in the Pg group. Lung lesions： The Pg+CIA group exhibited marked alveolar inflammation， interstitial inflammatory cell infiltration， and alveolar wall thickening， with pronounced blue staining of collagen fibers. Histopathological scores and collagen area ratios were significantly higher than those of the Control， Pg， and CIA groups （P<0.05）. Lung protein and mRNA expression levels of α-SMA， ColⅠ， and FN were markedly increased， and mRNA levels of IL-6， TNF-α， and IL-1β were significantly elevated compared to the Control group （P<0.05）. Serology： The Pg+CIA group showed significantly higher levels of CCP， Pg， and IgG compared with the Control， Pg， and CIA groups （P<0.05）. ConclusionDBA/1 mice subjected to Pg infection combined with CIA exhibited pronounced symptoms and pathological features of RA-ILD， along with elevated serum anti-CCP antibody levels. This model represents a novel RA-ILD mouse model， providing a valuable experimental tool for investigating RA-ILD pathogenesis and developing new therapeutics， and serves as a basis for establishing anti-cyclic citrullinated peptide antibody （ACPA）-positive RA-ILD animal models.

ObjectiveTo determine the optimal bedding depth of wood shavings and cage-changing interval for post-weaning (21-day-old) SPF C57BL/6J mice housed in open cages within a barrier environment. MethodsThree bedding groups with average depths of 3 cm, 4 cm, and 5 cm were established, forming six experimental groups (three groups each for female and male mice, with 60 mice per group and 20 mice per cage, totaling 18 cages). The mice were housed in accordance with the maximum housing density requirements specified in GB 14925—2023 Laboratory Animal—Environment and Housing Facilities. Indicators, including body weight, food intake, waste load, and bedding cleanliness, were continuously monitored in mice aged 21-54 days. ResultsAt the age of 21-54 days, the body weight of male mice in the 4 cm bedding group at 42 days was significantly higher than that in the 3 cm and 5 cm groups (P<0.01); at the age of 45-54 days, the waste load of male mice in the 4 cm group was significantly higher than that in the 3 cm group (P<0.05). There were no statistically significant differences in body weight, feed intake and waste load of female mice among each bedding height group (P>0.05). Gender comparison showed that the body weight, feed intake and waste load of male mice were significantly higher than those of female mice at multiple age groups (P<0.05). However, there was no statistically significant difference in cleanliness scores between female and male mice (P>0.05). The scores of mice in the 3 cm and 4 cm groups were close to 3 points from day 6 to day 12, and the scores of mice in the 5 cm group were close to 3 points on day 12. After 42 days of age, the cleanliness scores of each group increased rapidly, and the cage change cycle needed to be shortened to 4 days. Comprehensive recommendation: the cage change cycle for 3 cm and 4 cm bedding heights is 6 days, and it can be extended to 12 days at a height of 5 cm bedding, and shortened to 4 days after 42 days of age. ConclusionUnder the open-cage housing mode, a bedding depth of 4 cm combined with a 6-day cage-changing interval during the growth phase can maintain cage cleanliness through bedding adsorption while optimizing the use of bedding resources. This protocol successfully balances animal welfare assurance with facility operational efficiency and is suitable for the large-scale management of C57BL/6J mice and inbred strains with similar genetic backgrounds.

Objective: This study investigated the value of multiparametric MRI (mpMRI) in predicting Gleason score (GS) upgrading and downgrading in radical prostatectomy (RP) compared with presurgical biopsy. Materials and Methods: Clinical and mpMRI data were retrospectively collected from 219 patients with prostate disease between January 2015 and December 2021. All patients underwent systematic prostate biopsy followed by RP. MpMRI included conventional diffusion-weighted and dynamic contrast-enhanced imaging. Multivariable logistic regression analysis was performed to analyze the factors associated with GS upgrading and downgrading after RP. Receiver operating characteristic curve analysis was used to estimate the area under the curve (AUC) to indicate the performance of the multivariable logistic regression models in predicting GS upgrade and downgrade after RP. Results: The GS after RP was upgraded, downgraded, and unchanged in 92, 43, and 84 patients, respectively. The AUCs of the clinical (percentage of positive biopsy cores [PBCs], time from biopsy to RP) and mpMRI models (prostate cancer [PCa] location, Prostate Imaging Reporting and Data System [PI-RADS] v2.1 score) for predicting GS upgrading after RP were 0.714 and 0.749, respectively. The AUC of the combined diagnostic model (age, percentage of PBCs, tPSA, PCa location, and PIRADS v2.1 score) was 0.816, which was larger than that of the clinical factors alone (P < 0.001). The AUCs of the clinical (age, percentage of PBCs, ratio of free/total PSA [F/T]) and mpMRI models (PCa diameter, PCa location, and PI-RADS v2.1 score) for predicting GS downgrading after RP were 0.749 and 0.835, respectively. The AUC of the combined diagnostic model (age, percentage of PBCs, F/T, PCa diameter, PCa location, and PI-RADS v2.1 score) was 0.883, which was larger than that of the clinical factors alone (P < 0.001). Conclusion Combining clinical factors and mpMRI findings can predict GS upgrade and downgrade after RP more accurately than using clinical factors alone.

Background: Breast cancer is a common malignant tumor that has a high tendency to metastasis to the bone, leading to cancer-induced bone pain (CIBP). Ghrelin can not only stimulate appetite and regulate energy balance, but also alleviate CIBP by inducing NPY expression. Octanoic acid (OA), a type of medium chain fatty acids, provides an energy substrate and promotes acylation of ghrelin. However, it remains to be elucidated whether an OA-rich diet can alleviate CIBP by activating the acyl-ghrelin/NPY pathway. Methods: First, thirty-six Sprague–Dawley rats were randomly divided into the sham, CIBP, CIBP + OA (20), CIBP + OA (40), CIBP + OA (60) and CIBP + OA (80) groups to investigate the effects of diets with different ratios of OA on CIBP and the acyl-ghrelin/NPY pathway. Next, a ghrelin O-acyltransferase (GOAT) inhibitor was exogenously administered to investigate whether an OA-rich diet alleviated CIBP through increasing the level of acyl-ghrelin and activating the acyl-ghrelin/NPY pathway. Results: An OA-rich diet significantly alleviated nociceptive behaviors and increased the levels of acyl-ghrelin and NPY in a dose-dependent manner in cancer-bearing rats. With the exogenous administration of the GOAT inhibitor, the beneficial effects of an OA-rich diet on the acyl-ghrelin/NPY pathway and its pain-relieving effects were attenuated. Conclusions An OA-rich diet could alleviate CIBP through increasing the level of acyl-ghrelin and activating the acylghrelin/NPY pathway.

Non-alcoholic fatty liver disease(NAFLD)is a progressive liver disease caused by factors other than alcohol caused by heterotopic fat accumulation in the liver.In recent years,the incidence rate has been increasing,and there is no specific clinical drug.Studies have found that nuclear transcription factor κB(NF-κB)can activate inflammation and oxidative stress,which plays an important role in the pathogenesis of NAFLD.Traditional Chinese medicine is convenient to obtain and cheap.It can treat NAFLD through multiple channels with good clinical efficacy,and no obvious side effects have been found till now.Many studies have shown that traditional Chinese medicine can inhibit the occurrence and development of NAFLD by inhibiting the NF-κB signaling pathway.This article summarizes the research results of traditional Chinese medicine in treating NAFLD based on the NF-κB signaling pathway since 2021,for several traditional Chinese medicine extracts(flavonoids,terpenoids,polysaccharides,glycosides,alkaloids and phenolic compounds)and traditional Chinese medicine compound(Shugan Jianpi Fang,Erhuang Quzhi Granules,Fuzi Lizhong Decoction,Huangqin Decoction,Qinlian Hongqu Decoction,Jiangzhi Granules),which can inhibit the further development of NAFLD by improving liver inflammatory response,oxidative stress response,fibrosis,apoptosis,autophagy and pyroptosis through the NF-κB signaling pathway,in order to provide new ideas for future new drug development and clinical medication.

Objective To investigate and analyze the epidemiological characteristics and the causes of a suspected outbreak of carbapenem-resistant Acinetobacter baumannii(CRAB)infection,and provide basis for healthcare-asso-ciated infection(HAI)prevention and control.Methods Information of 3 patients with CRAB positive culture from the respiratory intensive care unit(RICU)of a hospital in May 2024 was collected.Microbiological sampling was performed in patients' ward environment,and the specimens were cultured and strains were identified.CRAB strains detected from the environment and patients were performed whole genome sequencing(WGS).Multiple de-partments jointly formulated and implemented comprehensive infection control measures,and the effectiveness were evaluated.Results CRAB was cultured from specimens of sputum and bedside office mice of 3 patients.WGS de-tection showed that ST2158 and ST1791 resistance genes were detected from both sputum and bedside office mice of 2 patients.After comprehensive assessment,2 patients were confirmed with HAI and 1 patient was confirmed with colonization,ruling out an outbreak of HAI.A total of 24 environmental specimens were taken for environmental hygiene monitoring,with a CRAB detection rate of 58.33％.CRAB detected from bedside mice and patients' spu-tum specimen had consistent CRAB drug susceptibility testing results.After implementing measures such as in-creasing the frequency of cleaning and disinfection of ward environment,strengthening the implementation of hand hygiene,and enhancing the supervision of department personnel as well as HAI prevention and control training,HAI was effectively controlled.Conclusion The possible transmission route of this suspected CRAB outbreak in RICU is the contamination of office mice,which caused healthcare workers carrying CRAB in their hands,leading to cross infection due to poor hand hygiene implementation of healthcare workers.Strengthening the cleaning and dis-infection of environmental surface and the management of hand hygiene of healthcare workers are key measures to prevent CRAB HAI.

Objective The aim of this study was to analyze the incidence,mortality,and epidemiological trends of malignant tumors in the cancer registration areas of Qinghai Province and provide a reference for the prevention and control strategies and meas-ures of malignant tumors.Methods According to the quality control standards for cancer registration,the data on malignant tumor in-cidence and mortality from 8 national cancer registration areas in Qinghai Province from 2014 to 2021 were collated.The crude inci-dence/mortality,age-standardized incidence/mortality rate by Chinese standard population(ASIRC/ASMRC)and World standard population(ASIRW/ASMRW),the cumulative rates(0-74 years old),and the age-specific incidence/mortality of malignant tumors were calculated for different sexes and regions.The Joinpoint 4.9.0.0 software was used to calculate the average annual percentage change(AAPC)and conduct trend analysis.Results The crude incidence of malignant tumors in the cancer registration areas of Qinghai Province from 2014 to 2021 was 221.25/100,000(243.31/100,000 for males and 198.68/100,000 for females),the ASIRC was 199.48/100,000(229.13/100,000 for males and 173.34/100,000 for females),the ASIRW was 196.38/100,000(228.32/100,000 for males and 167.97/100,000 for females).The cumulative rate for those aged 0-74 years was 21.57％;the crude mortali-ty of malignant tumors was 131.90/100,000(163.86/100,000 for males and 99.20/100,000 for females),the ASMRC was 121.07/100,000(157.33/100,000 for males and 87.45/100,000 for females),the ASMRW was 120.53/100,000(157.54/100,000 for males and 86.31/100,000 for females),and the cumulative rate for those aged 0-74 years was 12.79％.The crude incidence,ASIRC,ASIRW,crude mortality,ASMRC and ASMRW were all higher in males than those in females.Both the crude incidence and mortality of malignant tumors increased with age.The crude incidence rate increased rapidly after age 45,peaked in the 80-84 age group(2,352.29 per 100,000),and declined slightly in the 85+age group.The crude mortality increased rapidly after age 50,peaked in the 85+age group(2,305.44 per 100,000).The crude incidence(AAPC=5.68％,95％CI:3.48％-7.93％,P＜0.05)and erude mortality(AAPC=3.67％,95％CI:2.44％-4.91％,P＜0.05)of malignant tumors showed an overall upward trend from 2014 to 2021.The ASIRC(AAPC=-0.12％,95％CI:-3.70％-3.59％,P＞0.05)remained stable,while the ASMRC(AAPC=-2.81％,95％CI:-3.28％--2.03％,P＜0.05)showed a downward trend.The top five malignant tumors in terms of crude incidence were stom-ach cancer,lung cancer,liver cancer,female breast cancer,and cervical cancer,respectively;the top five malignant tumors in terms of crude mortality were stomach cancer,lung cancer,liver cancer,esophagus cancer,and colorectal cancer,respectively.Conclusion From 2014 to 2021,the incidence and mortality of malignant tumors in the Qinghai Province cancerregistration areas showed an in-creasing trend,with higher rates in males than those in females.It is recommended that targeted prevention and control measures should be implemented for people aged 45 and older,with stomach cancer,liver cancer,and cervical cancer as key cancers.

Objective:To elucidate the correlation between phase angle and malnutrition and to determine the cut-off value for phase angle to predict malnutrition in pancreatic cancer patients.Methods:This prospective cross-sectional study enrolled patients with pancreatic cancer hospitalized in the Department of Hepato-pancreato biliary Surgery at Beijing Hospital between December 2021 and March 2024. Baseline data, diet survey results, and body composition of these patients were recorded. Phase angle was measured with the InBody 720(Biospace, Korea). The Global Leadership Initiative on Malnutrition (GLIM) criteria were used to diagnose malnutrition.Results:A total of 110 cases (75 males and 35 females) aged 29-87(63.00±12.37) years were included. The prevalence of malnutrition was 63.6% (70/111) among the patients. Patients were divided into malnutrition ( n=77) and non-malnutrition ( n=33) groups as per the GLIM criteria. Phase angle was significantly lower in the malnutrition group than in the non-malnutrition group ( t=-3.808, P<0.001). Positive correlations were found between phase angle and body mass index, appendicular skeletal muscle mass index, fat-free mass index , fat-free mass, total energy intake, total protein, albumin, and prealbumin (all P<0.05).After adjusting for sex and age, low phase Angle remained an independent risk factor for malnutrition ( OR=3.809, 95% CI: 1.150-12.612, P=0.029). The cut-off values of phase angle for predicting malnutrition were 4.43 for males (with a sensitivity of 0.955, specificity of 0.585, area under the curve of 0.636; 95% CI: 0.508-0.763, P=0.037) and 4.54 for females (with a sensitivity of 1.000, specificity of 0.708, area under the curve of 0.799; 95% CI: 0.653-0.946, P<0.001). Conclusion:Phase angle may serve as a valid and simple indicator of malnutrition in pancreatic cancer patients.

Objective To investigate the current status of adverse drug reaction(ADR)monitoring in medical institu-tions under China's pharmacovigilance framework in Guangdong Province,and to propose evidence-based strategies for enhancing institutional monitoring capabilities.Methods A cross-sectional survey was conducted using a structured questionnaire devel-oped in alignment with national regulatory requirements and expert consensus.Data were collected from 65 medical institutions,including general hospitals,traditional Chinese medicine hospitals,and maternal/children's hospitals,across 21 prefecture-level cities in Guangdong.Descriptive and comparative analyses were performed to evaluate institutional practices.Results All 65 in-stitutions submitted valid responses.Among them,63(96.9％)had established standardized ADR reporting protocols,with 93.8％(61/65)delegating oversight to pharmacy departments.ADR data were predominantly collected via institutional informa-tion systems(67.7％,44/65),though these systems focused on passive reporting and basic data aggregation,lacking functional-ities for active signal detection or risk alert mechanisms.Significant disparities(P＜0.05)were observed across hospitals of dif-ferent tiers in reporting modalities,system sophistication,analytical frequency,and early warning implementation.Notably,mo-nitoring practices for conditionally approved drugs(e.g.,emergency-authorized therapeutics)exhibited systemic deficiencies.Conclusions To address these gaps,the following measures are recommended:Accelerating the adoption of intelligent monito-ring systems to enable real-time ADR detection and predictive analytics;Implementing tiered resource allocation policies to ensure equitable capability development;Establishing specialized protocols for high-risk pharmaceuticals,particularly conditionally ap-proved and fast-tracked drugs;Strengthening interdisciplinary training programs to improve pharmacovigilance literacy among healthcare practitioners.These interventions aim to foster a proactive risk management culture and advance patient safety within China's evolving healthcare landscape.
