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 conduct a clinical comprehensive evaluation of five marketed thrombopoietin receptor agonists （TPO-RA） approved in China， providing quantitative evidence for drug selection and therapeutic decision-making in medical institutions. METHODS Relevant data on Romiplostim for injection， Eltrombopag olamine tablets， Herombopag olamine tablets， Avatrombopag maleate tablets， and Lusutrombopag tablets were collected. Based on the Chinese Rapid Guide for Drug Evaluation and Selection in Medical Institutions （Second Edition）， 12 formulations of these five TPO-RA were scored quantitatively and comparatively across five dimensions： pharmacological characteristics， efficacy， safety， cost-effectiveness， and other attributes. RESULTS The comprehensive scores of the 12 formulations ranged from 62.56 to 75.50 points， with most scoring ≥70 points. Using the highest-scoring formulation for each generic name as a representative， the overall rankings of the five TPO-RA were as follows： Lusutrombopag tablets （75.50 points）， Eltrombopag olamine tablets （75.10 points）， Avatrombopag maleate tablets （70.40 points）， Romiplostim for injection （63.93 points）， and Herombopag olamine tablets （63.52 points）. Lusutrombopag tablets scored relatively high in pharmacological characteristics， safety， and cost-effectiveness， while Eltrombopag olamine tablets performed well in efficacy and cost-effectiveness. The other formulations showed varying scores across evaluation dimensions. CONCLUSIONS The five TPO-RA demonstrate favorable overall clinical value， with Lusutrombopag tablets and Eltrombopag olamine tablets ranking higher in comprehensive scores， these two drugs should be prioritized in drug selection and formula optimization by medical institutions.

Breast cancer is a malignant tumor that occurs in the glandular epithelium of the breast, and it is one of the most common tumors that seriously affect the physical and mental health of women. With the aggravation of population aging, the incidence of breast cancer in the elderly has increased year by year in recent years. Elderly patients with breast cancer often have a variety of underlying diseases, and their prognosis is usually related to many factors such as cancer staging, cancer classification, treatment status and health status, with a significant difference in survival rate among patients. Due to the unique clinical and pathological characteristics of elderly patients with breast cancer compared to young and middle-aged patients, there are many studies on the treatment of elderly breast cancer patients in the past, and there are few reviews on the influencing factors of prognosis in elderly patients. This paper reviews the research progress of influencing factors of prognosis in elderly patients with breast cancer from the aspects of clinicopathological factors, treatment options and prognosis factors, in order to provide a reference for clinical determination of treatment options for elderly patients with breast cancer in the future.

Objective To assess the current status of microbial and parasitic quality control for laboratory animals in Jiangxi Province by analyzing microbiological and parasitic test results from production facilities between 2020 and 2024, and to provide a basis for enhancing quality control measures. MethodsIn accordance with the current national standards for laboratory animals at the time of testing, the Jiangxi Provincial Laboratory Animal Quality Inspection Station (affiliated to Institute of Occupational Medicine of Jiangxi) conducted microbial and parasitic testing on 451 laboratory animals of 4 species from 6 laboratory animal production units in Jiangxi Province between 2020 and 2024, and analyzed the quality status of laboratory animals in the province. ResultsPasteurella pneumotropica was detected in one mouse sample in 2020, with a detection rate of 5.00%. Pseudomonas aeruginosa was detected in one mouse sample and mouse hepatitis virus antibody was detected in another mouse sample in 2023, with a detection rate of 2.78%, respectively. No microorganisms or parasites that should be excluded from SPF grade mice as specified in the national standards were detected in 2021, 2022, or 2024, with a qualification rate of 100.00%. Pasteurella pneumotropica was detected in four rat samples in 2020, with a detection rate of 20.00%. Pseudomonas aeruginosa was detected in two rat samples in 2021, with a detection rate of 10.00%, and Tyzzer's disease agent antibody was detected in four rat samples in 2024, with a detection rate of 10.00%. No microorganisms or parasites that should be excluded from SPF grade rats as specified in the national standards were detected in 2022 or 2023, with a qualification rate of 100.00%. For rabbits and guinea pigs, no microorganisms or parasites required to be tested for conventional grade rabbits and guinea pigs as specified in the national standards were detected from 2020 to 2024, with the qualification rate of both species reaching 100.00%. ConclusionBased on the microbial and parasitic testing results, the quality of rabbits and guinea pigs in Jiangxi Province is satisfactory. However, some issues persist with rats and mice. It is recommended to enhance the quality of experimental animals in Jiangxi Province by increasing the frequency of random inspections by quality testing units or by improving the self-inspection capabilities of production and user facilities.

BACKGROUND:Studies have shown that patients with premature ovarian failure have changes in the structure of intestinal flora and that imbalance of intestinal microbiota may be one of the important mechanisms in the development of premature ovarian failure. OBJECTIVE:To investigate the effect of Liuwei Dihuang Wan on oxidative stress and intestinal microbiota in premature ovarian failure mice induced by cyclophosphamide. METHODS:Forty-five female ICR mice were randomized into three groups:blank group(normal mice),model group(premature ovarian failure mice),and Liuwei Dihuang Wan group.A mouse model of premature ovarian failure was prepared by one-time intraperitoneal injection of cyclophosphamide(120 mg/kg)in the latter two groups.After successful modeling,the Liuwei Dihuang Wan group was intragastrically administered for 28 continuous days,and the other two groups were intragastrically administered with the same amount of normal saline for 28 days.Mouse body mass was recorded weekly and ovarian index was calculated.The development of mouse follicles was observed using hematoxylin-eosin staining.ELISA method was used to detect serum levels of anti-Mullerian hormone,estradiol,follicle stimulating hormone,superoxide dismutase,glutathione peroxidase,and malondialdehyde.Meanwhile,the gut microbiome of all mice was detected through 16S rDNA sequencing. RESULTS AND CONCLUSION:The mice in the model group had loose hair,decreased vigor and grip strength,almost no increase in body mass,and decreased ovarian index.Whereas,the mouse body mass and ovarian index were increased after treatment with Liuwei Dihuang Wan(P<0.05).The estrous cycle of mice in the model group was disorganized;Liuwei Dihuang Wan could restore the estrous cycle and reduce the number of atretic follicles in mice with premature ovarian failure.The serum levels of follicle stimulating hormone and malondialdehyde in the model group significantly increased(P<0.01),while the levels of estradiol,anti-Mullerian hormone,superoxide dismutase,and glutathione peroxidase significantly decreased(P<0.01).Liuwei Dihuang Wan could significantly decrease the serum levels of follicle stimulating hormone and malondialdehyde(P<0.01),and increase the levels of estradiol,anti-Mullerian hormone,superoxide dismutase,and glutathione peroxidase.According to the 16S rDNA sequencing results,Liuwei Dihuang Wan could regulate the abundance and diversity of intestinal microbiota,and increase the relative abundance of beneficial bacteria.KEGG pathway analysis showed that the intestinal microbiota and metabolic pathways,biosynthesis of secondary metabolites,microbial metabolism in different environments,and biosynthesis of amino acids were regulated by Liuwei Dihuang Wan.To conclude,the changes in the structure of intestinal microbiome may be one of the potential mechanisms of Liuwei Dihuang Wan in treating premature ovarian failure.Liuwei Dihuang Wan can regulate the structure of intestinal microbiome,increase the number of beneficial bacteria,reduce the number of harmful bacteria,and thus improve the balance of intestinal microbiota.This regulatory effect helps to reduce oxidative stress levels and further inhibit ovarian oxidative stress in mice with premature ovarian failure.

BACKGROUND:The micro/nanostructured gradient biomimetic surface of implant materials can simulate the structure of the extracellular environment in human bone tissue,thereby achieving perfect bone integration function.However,further research is needed on the mechanisms by which the surface microstructure of bone implant materials regulates cell function and promotes osteogenesis. OBJECTIVE:To analyze the effect of titanium sheet microstructure surface on osteogenic differentiation of MC3T3-E1 osteoblasts. METHODS:(1)At a constant voltage of 5 V or 20 V,nanotube arrays of different diameters were prepared on the surface of titanium sheets by acid etching and anodic oxidation techniques,and were recorded as group R5 and group R20,respectively.The surface morphology,roughness,and hydrophilicity of pure titanium sheet(without acid etching or anodizing treatment)were measured in group R5 and group R20.(2)MC3T3-E1 osteoblasts of logarithmic growth stage were inoculated on the surface of pure titanium sheets,R5 group and R20 group respectively.After 24 hours of osteogenic induction culture,the expression of mechanical sensitive channel protein 1 was analyzed by RT-PCR and immunofluorescence staining.Osteoblast inducible base with or without the mechanosensitive channel protein 1 activator Yada1 was added,and alkaline phosphatase staining was performed after 7 days of culture.Alizarin red staining was performed after 14 days of culture. RESULTS AND CONCLUSION:(1)The surface of pure titanium sheets was smooth under scanning electron microscope.Relatively uniform and orderly nanotube arrays with average diameters of about 30 nm and 100 nm were observed on the surface of titanium sheets of groups R5 and R20,respectively.The results of scanning electron microscope were further verified by atomic force microscopy.The surface roughness of titanium sheet of group R5 was higher than that of pure titanium(P<0.05),and the water contact angle was lower than that of pure titanium(P<0.05).The surface roughness of titanium sheet in group R20 was higher than that in group R5(P<0.05),and the water contact angle was lower than that in group R5(P<0.05).(2)RT-PCR and immunofluorescence staining showed that the expression of mechanosensitive channel protein 1 in group R5 was higher than that in pure titanium group(P<0.05),and the expression of mechanosensitive channel protein 1 in group R20 was higher than that in group R5(P<0.05).Under the osteogenic induction,compared with the condition without Yada1,there were no significant changes in the activity of alkaline phosphatase and the deposition of calcified nodules in pure titanium group after Yada1 addition,while the activity of alkaline phosphatase and the deposition of calcified nodules in groups R5 and R20 after Yada1 addition were significantly increased(P<0.05).With or without Yada1,the alkaline phosphatase activity and calcified nodule deposition in group R5 were higher than those in pure titanium group(P<0.05),and the alkaline phosphatase activity and calcified nodule deposition in group R20 were higher than those in group R5(P<0.05).(3)The results show that the surface microstructure of titanium sheet can promote the osteogenic differentiation of osteoblast MC3T3-E1 by activating mechanosensitive channel protein 1.

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 explore the occurrence risk of enteral nutrition intolerance and analyze its influencing factors in 302 elderly critically ill patients. Methods The clinical case data of elderly critically ill patients in department of elderly cadres of the hospital were retrospectively analyzed from January 2019 to January 2024. According to the occurrence of enteral nutrition intolerance or not, they were divided into occurrence group (n=156) and non-occurrence group (n=146). The risk of nutritional intolerance in elderly critically ill patients was evaluated by feeding intolerance risk assessment form, and the influencing factors of enteral nutrition intolerance were analyzed by multivariate logistic regression analysis. Results Among the 302 elderly patients with critical illness, 53.31% (161/302) had high risk of enteral nutrition intolerance, and 51.66% (156/302) had enteral nutrition intolerance. Multivariate logistic analysis revealed that CRP level>10mg/L, APACHE-II score≥20 points, Lac≥3mmol/L and hypoalbuminemia were risk factors in elderly critically ill patients (OR=1.806, 2.977, 8.232, 3.031, P=0.011, 0.001, 0.041, 0.047), and addition of dietary fiber was a protective factor for enteral nutrition intolerance (OR=1.652, P=0.037). Conclusion The risk of enteral nutrition intolerance is high in elderly critically ill patients. Lac level, CRP level, hypoalbuminemia, and APACHE-II score of patients are independent risk factors for enteral nutrition intolerance, and addition of dietary fiber is a protective factor. It is necessary to take targeted interventions for patients according to the above factors to minimize the occurrence of enteral nutrition intolerance.

Epilepsy is a chronic neurological disease characterized by abnormal synchronous discharges of brain neurons. The mutation of GRIN1， a key gene encoding the essential GluN1 subunit of N-methyl-D-aspartate （NMDA） receptors， is closely associated with the pathogenesis and progression of epilepsy. This review summarizes research advances in GRIN1 mutation-related epilepsy， with a focus on its molecular mechanisms， clinical phenotypes， factors influencing phenotypic heterogeneity， and treatment strategies. In terms of molecular mechanisms， GRIN1 mutations affect NMDA receptor function through gain-of-function and loss-of-function mechanisms. Clinical phenotypes show significant heterogeneity， including seizure types， age of onset， and comorbid neurodevelopmental disorders. This heterogeneity may be related to the domain where the mutation is located， the mutation type， and the degree of impact on receptor function. Regarding treatment， gain-of-function mutations can be managed with NMDA receptor antagonists， while loss-of-function mutations may be treated with positive allosteric modulators. The ketogenic diet has also demonstrated potential therapeutic effects. This review aims to provide references for basic research and clinical translation in GRIN1 mutation-related epilepsy， and to promote the development of precision diagnosis and treatment.

ObjectiveTo investigate the efficacy and mechanism of Polygoni Cuspidati Rhizoma et Radix （Huzhang） in treating respiratory syncytial virus（RSV） infection by regulating pulmonary surfactant lipid homeostasis through lipidomics. MethodsSixty BALB/c mice were randomly divided into the blank group， model group， positive group（ribavirin group， 46 mg·kg^-1）， and low- and high-dose Huzhang groups（0.75， 2.25 g·kg^-1）， with 12 mice in each group. Except for the blank group， all other groups were infected with RSV via intranasal instillation. The drug intervention groups were given corresponding doses of drug by gavage for 3 consecutive days， while normal saline was used in the blank and model groups. Hematoxylin-eosin（HE） staining was used to observe pathological changes in mouse lung tissue. Real-time fluorescence quantitative polymerase chain reaction（Real-time PCR） was employed to detect viral loads［RSV-nucleoprotein（N） and RSV-glycoprotein（G） mRNA］ and inflammatory factor levels［interleukin（IL）-1β and tumor necrosis factor（TNF）-α mRNA］ in the lung tissue. Mouse bronchoalveolar lavage fluid was collected to detect the levels of pulmonary surfactant lipids through ultra-high performance liquid chromatography-quadrupole-electrostatic field orbitrap high-resolution mass spectrometry（UPLC-Q-Exactive Orbitrap-MS）， followed by principal component analysis and differential lipid identification. ResultsCompared with the blank group， the model group exhibited extensive inflammatory cell infiltration， congestion， and tissue damage in the lungs， and the pathological score and lung index of lung tissue significantly increased（P<0.01）， along with significantly elevated mRNA expressions of RSV-N， RSV-G， IL-1β， and TNF-α（P<0.01）. Compared with the model group， different doses of Huzhang and ribavirin significantly reduced the pathological scores of the lung tissue and lung index（P<0.01）. In addition， the mRNA levels of RSV-N， RSV-G and TNF-α in the lungs significantly decreased in the Huzhang high dose group（P<0.01）. Lipidomics analysis identified multiple significantly changed differential metabolites. Compared with the blank group， the model group showed obvious abnormal lipid metabolism， which was manifested by the elevated levels of prostaglandin（PG）， ceramide（Cer）， phosphatidylcholine（PC）， phosphatidylethanolamine（PE）， phosphatidylinositol（PI）， sphingomyelin（SM）， and the decreased levels of diglycerides（DG） and acylethanolamine（NAE）. After the intervention of low dose of Huzhang， the above lipid metabolites showed a significant reversal trend， while the intervention of high dose of Huzhang could regulate levels of PI lipids， PG lipids and PC lipids. ConclusionHuzhang can significantly reduce the viral load of lung tissue and improve lung inflammation in RSV-infected mice. The underlying mechanism may be related to the maintenance of homeostasis in pulmonary surfactant lipids such as PI and PG.
