ObjectiveTo construct a large language model （LLM）-based intelligent pre-consultation system for traditional Chinese medicine （TCM） to improve efficacy of clinical practice. MethodsA TCM large language model was fine-tuned using DeepSpeed ZeRO-3 distributed training strategy based on YAYI 2-30B. A weighted undirected graph network was designed and an agent-based syndrome differentiation model was established based on relationship data extracted from TCM literature and clinical records. An agent collaboration framework was developed to integrate the TCM LLM with the syndrome differentiation model. Model performance was comprehensively evaluated by Loss function， BLEU-4， and ROUGE-L metrics， through which training convergence， text generation quality， and language understanding capability were assessed. Professional knowledge test sets were developed to evaluate system proficiency in TCM physician licensure content， TCM pharmacist licensure content， TCM symptom terminology recognition， and meridian identification. Clinical tests were conducted to compare the system with attending physicians in terms of diagnostic accuracy， consultation rounds， and consultation duration. ResultsAfter 100 000 iterations， the training loss value was gradually stabilized at about 0.7±0.08， indicating that the TCM-LLM has been trained and has good generalization ability. The TCM-LLM scored 0.38 in BLEU-4 and 0.62 in ROUGE-L， suggesting that its natural language processing ability meets the standard. We obtained 2715 symptom terms， 505 relationships between diseases and syndromes， 1011 relationships between diseases and main symptoms， and 1 303 600 relationships among different symptoms， and constructed the Agent of syndrome differentiation model. The accuracy rates in the simulated tests for TCM practitioners， licensed pharmacists of Chinese materia medica， recognition of TCM symptom terminology， and meridian recognition were 94.09%， 78.00%， 87.50%， and 68.80%， respectively. In clinical tests， the syndrome differentiation accuracy of the system reached 88.33%， with fewer consultation rounds and shorter consultation time compared to the attending physicians （P＜0.01）， suggesting that the system has a certain pre- consultation ability. ConclusionThe LLM-based intelligent TCM pre-diagnosis system could simulate diagnostic thinking of TCM physicians to a certain extent. After understanding the patients' natural language， it collects all the patient's symptom through guided questioning， thereby enhancing the diagnostic and treatment efficiency of physicians as well as the consultation experience of the patients.

ObjectiveTo investigate the effect and underlying mechanism of the Wulao Qisun prescription on pathological new bone formation in ankylosing spondylitis （AS）. MethodsSynovial fibroblasts were isolated from the hip joints of AS patients and observed under a microscope to assess cell morphology. The cells were identified using immunofluorescence staining. The isolated AS fibroblasts were divided into blank group， low drug-containing serum group， medium drug-containing serum group， high drug-containing serum group， and positive drug group. After drug intervention， cell proliferation was measured using the cell counting kit-8 （CCK-8） assay to observe fibroblast growth and determine the optimal intervention time. Alkaline phosphatase （ALP） activity was measured using the alkaline phosphatase assay. Protein expression of osteocalcin （OCN）， osteopontin （OPN）， and runt-related transcription factor 2 （Runx2） was detected by Western blot. The mRNA expression levels of Wnt5a， β-catenin， and Dickkopf-1 （DKK-1） were measured by real-time quantitative polymerase chain reaction （Real-time PCR）. ResultsCompared with the blank group， each drug-containing serum group of Wulao Qisun prescription and the positive drug group inhibited the proliferation of AS fibroblasts and reduced ALP expression （P<0.01）. Compared with the blank group， the low drug-containing serum group of Wulao Qisun prescription downregulated β-catenin mRNA expression （P<0.05）. The medium and high drug-containing serum groups and the positive drug group significantly downregulated Wnt5a and β-catenin mRNA expression （P<0.05， P<0.01）， with the positive drug group showing the most pronounced effect （P<0.01）. The high drug-containing serum group and the positive drug group significantly upregulated DKK-1 mRNA expression （P<0.01）. Compared with the blank group， the low drug-containing serum group of Wulao Qisun prescription inhibited the expression of OPN and Runx2 proteins （P<0.05， P<0.01）， while the medium and high drug-containing serum groups and the positive drug group inhibited the expression of OCN， OPN， and Runx2 proteins （P<0.05， P<0.01）. ConclusionThe Wulao Qisun prescription can inhibit the proliferation and osteogenic differentiation of AS fibroblasts， thereby delaying the formation of pathological new bone in AS. The possible mechanism involves the regulation of Wnt/β-catenin-related gene expression， further inhibiting the transcription of downstream target genes.

Objective To explore the effect of metformin combined with insulin detemir on intestinal flora in patients with gestational diabetes mellitus (GDM). Methods A total of 176 patients with GDM admitted to Luzhou People's Hospital from May 2022 to July 2023 were selected and randomly divided into a single drug group and a combined group, with 88 cases in each group. The single drug group was treated with insulin detemir, and the combined group was given metformin combined with insulin detemir. The glucose metabolism levels and intestinal flora distribution were compared between the two groups before treatment and during delivery. The maternal-infant outcomes were statistically analyzed and compared between the two groups. Results During delivery, the levels of fasting plasma glucose (FPG), glycosylated hemoglobin (HbAlc), and largest amplitude of glycemic excursions (LAGE), and the contents of Enterobacterium, Enterococcus and Escherichia coli in both groups were reduced compared with those before treatment, and the above indicators in the combined group were lower than those in the single drug group (all P<0.05). The contents of Bifidobacterium and Lactobacillus were increased in both groups, and the indicators were higher in the combined group than those in the single drug group (all P<0.05). There was no significant difference in adverse maternal-infant outcomes between the two groups (P>0.05). Conclusion Metformin combined with insulin detemir can effectively reduce blood glucose levels and improve intestinal flora distribution in patients with GDM, without increasing adverse maternal-infant outcomes.

In this work, starting from 4-hydroxycoumarin, three series of 22 coumarin derivatives, among which 8 have not been reported in the literature, were synthesized and their in vitro anti-inflammatory activities and mechanisms of action were preliminarily investigated using mouse macrophage model. The results showed that most of the derivatives could significantly inhibit the production of pro-inflammatory factor NO, with compounds 2e, 2f, 2g, 2h, 2i, 2j, 4e, and 4f showing better anti-inflammatory activity than the positive control drug dexamethasone. Further experiments showed that compounds 2h and 4f significantly inhibited the production of pro-inflammatory factors IL-6, TNF-α and IL-1β in RAW264.7 macrophages, and could, therefore, be used as lead compounds for further studies.

OBJECTIVE To evaluate the efficacy， safety and cost-effectiveness of toripalimab （Tor） combined with chemotherapy （CT） in the treatment of locally advanced or metastatic non-small cell lung cancer （NSCLC）. METHODS PubMed， the Cochrane Library， Embase， Web of Science， CBM， CNKI， Wanfang Data， and Health Technology Assessment （HTA） related websites were searched to collect the HTA reports， systematic reviews/meta-analyses and pharmacoeconomic studies of Tor+CT in the treatment of locally advanced or metastatic NSCLC from database/website inception to March 31， 2025. After data extraction and quality evaluation， the results of the included studies were analyzed descriptively. RESULTS A total of eleven studies were included， involving five systematic reviews/meta-analyses， and six pharmacoeconomic studies. Among the five systematic reviews/ meta-analyses， two were of high quality， while there was one each of moderate， low， and very low quality. All six pharmacoeconomic studies were of good quality. In terms of efficacy， compared with CT， Tor+CT significantly improved patients’ progression-free survival （PFS） and overall survival （P＜0.05）. In addition， compared with ipilimumab+CT， durvalumab， durvalumab+tremelimumab and sugemalimab+CT， Tor+CT could also improve the PFS （P＜0.05）. In terms of safety， there was no significant difference in the incidence of grade≥3 adverse events between patients receiving Tor+CT and CT （P＞0.05）； while Tor+CT had a lower incidence of grade≥3 adverse E-mail： events， compared with camrelizumab+CT， pembrolizumab+ 3233255290@qq.com ipilimumab， nivolumab+CT and atezolizumab+CT （P＜0.05）.In terms of cost-effectiveness， Tor+CT treatment had certain cost-effectiveness advantages， compared with CT. CONCLUSIONS Compared with CT， other programmed death-1/programmed death-ligand 1 inhibitors alone， or their combination with CT， Tor+CT for the treatment of locally advanced or metastatic NSCLC has good efficacy， safety and cost-effectiveness.

Objective:To investigate the application value of a new clinical probation log designed based on the subjective-objective-assessment-plan (SOAP) structured medical record.Methods:Quantitative and qualitative studies were conducted among 97 students in the autumn semester to evaluate the effect of the new clinical probation log based on the SOAP structured medical record on their academic performance and clinical thinking. SPSS 26.0 was used to perform the t-test and ANOVA. Results:The students using the new version had a significantly better score (96.29±1.38) than those using the old version (93.53±1.60) ( P<0.001), while the multivariate analysis showed that the students who first used the old version and then switched to the new version had a significantly better improvement in the score compared with those who first used the new version and then switched to the old version ( P<0.001). The qualitative interview showed that it was necessary to use handwritten internship log, and compared with the old version, the new version could better promote the ordered clinical thinking of students. The teacher comments could give feedbacks, and all the students interviewed thought that the new version held promise for clinical application. Conclusions:The clinical probation log based on the SOAP structured medical record can help to improve the effectiveness of probation and cultivate clinical thinking ability, and thus it holds promise for application in clinical probation teaching.

Objective:To provide references for the application of finite element model in the study of cervical vertebra by statistically analysing the frequency, numerical value, properties, and boundary setting of the finite element model and the corresponding material features as well as boundary settings in the literature.Methods:The literature on cervical vertebra-related finite element models was collected from CNKI, Wanfang, VIP, PubMed, Web of Science, and Embase databases from January 2013 to December 2023. The quality assessment was followed by manual screening. The data sources, application classification, material properties (Young’s modulus and Poisson’s ratio), and boundary conditions of cervical vertebra, cervical intervertebral, and cervical ligaments were statistically analyzed.Results:A total of 102 papers were included. The finite element models of the cervical vertebra were derived from medical image reconstruction modeling techniques, predominantly CT plain scan and magnetic resonance imaging. Among the 102 cervical vertebra models, the C3-C7 (lower cervical segment) model appeared with the highest frequency (19). The Young’s modulus of the cortical bone, cancellous bone, and posterior structure of cervical vertebrae were set at about 12 000 or 10 000, 440, and 3 600 MPa, respectively, and the Poisson’s ratios were mainly set at about 0.29 or 0.30, 0.29, and 0.29. The Young’s modulus of the cervical intervertebral disc endplate, nucleus pulposus, and annulus fibrosus were concentrated around 500 or 2 000, 1, and 100 MPa, respectively, and the Poisson’s ratios were set at about 0.40, 0.50, and 0.40, respectively. The Young’s modulus of the anterior longitudinal ligament, posterior longitudinal ligament, transverse ligament, ligamentum flavum, interspinous ligament, capsular ligament, and articular cartilage of the cervical spine were set around 30, 20, 20, 6-10, 4-8, 10 or 20, 10 MPa, and the Poisson’s ratios were set at aoubt 0.30, 0.30, 0.30, 0.30, 0.30, 0.40, and 0.30, respectively. The Young’s modulus of the upper cervical interdental ligament, lamina, cruciate ligament, nuchal ligament, and pterygoid ligament were set at about 10, 10, 10 or 20, 20, and 5 MPa, respectively, and the Poisson’s ratios were set at about 0.30. Head weight settings were more common at 50, 74, and 100 N.Conclusions:The finite element model of the cervical vertebra has great value in the study of cervical spondylosis, but further optimization is still needed in the assignment of material properties, mesh division, and model verification to improve the accuracy and clinical applicability of the model.

Objective To study the effect of fine particulate matter(particulate matter 2.5,PM2.5)exposure on hepatic lymphangiogenesis in C57BL/6J mice and metabolic-associated fatty liver disease(MAFLD)model mice,and to provide a novel target for prevention and treatment of PM2.5-induced liver injury.Methods Forty male C57BL/6J mice were randomly divided into a control group,PM2.5 group,MAFLD group,and PM2.5-MAFLD group.Mice in the MAFLD and PM2.5-MAFLD groups were fed high-fat diet for 12 weeks,and mice in the other groups were fed normal chow diet.From weeks 13 to 16,mice in the PM2.5 and PM2.5-MAFLD groups were exposed to PM2.5 by tracheal instillation(twice per week),and mice in the other groups were instilled with saline at the same time.All animals were euthanized 24 h after the last PM2.5 instillation.Serum alanine aminotransferase(ALT)and aspartate aminotransferase(AST)were measured,and the expression of LYVE1 in liver tissues was visualized using immunofluorescence staining.Hepatic oxidative stress markers levels(4-HNE and GSH/GSSG)were measured.The protein expression levels of lymphangiogenesis markers(PROX1 and LYVE1),lymphangiogenesis regulatory protein VEGF-C,and the lymphatic junctional function marker VE-cadherin in liver tissue were determined using Western Blot.Results PM2.5 exposure significantly increased the levels of serum AST and ALT,markedly decreased the protein expression of PROX1 and LYVE1,increased the protein expression of VEGF-C and VE-cadherin in the liver,increased the level of 4-HNE,and decreased the T-GSH/GSSG ratio in livers of mice in the MAFLD group(P＜0.05).However,PM2.5 exposure did not affect the levels of serum AST and ALT,protein expression of PROX1,LYVE1,or VEGF-C;level of 4-HNE;or T-GSH/GSSG ratio in the livers of the C57BL/6J mice(P＞0.05).Conclusions PM2.5 exposure obviously aggravated hepatic oxidative injury and reduced hepatic lymphangiogenesis by reducing the VEGF-C concentration in the livers of MAFLD model mice.

Objective:To explore the psychological development process of suicide ideation-to-action in male prisoners,providing a basis for suicide prevention and intervention for them.Methods:Thirty-five male prisoners with self-reported or prison police assessment of suicide risk and history of self-injury and suicide were selected for in-depth interviews.Using grounded theory to code data,explore the evolution process and influencing factors of prisoners from suicidal ideation to suicide-related actions.Results:Prisoners were divided into three stages from the emergence of suicidal ideation to suicide-related actions,namely the seed stage of cumulative environmental effects(stage 1),the germination and development stage of suicidal ideation(stage 2),and the action strategy selection stage(stage 3).The process mainly contained 4 dimensions,namely situational risk factors,negative psychological experiences,psychological risk factors and psychological protection factors.Conclusion:The suicide psychological development process of prisoners is a gradual process.Suicide intervention should prioritize prevention,remove risk factors,enhance protective factors,and carry out personalized intervention based on different pathways.

Objective To explore and implement a differentiated management strategy for multi-campus hospitals to improve patient experience and satisfaction,and achieve the goal of homogenized management.Methods In December 2021,the Picker Patient Experience Questionnaire was used to survey the patient experience at 3 campuses of a tertiary A hospital in Hangzhou,and the reasons for the differences were analyzed.Based on policy document reviews,special group discussions,and expert meetings,differentiated management strategy for multi-campus hospitals was formulated.The patient experience and satisfaction before(December 2021)and after(December 2023)the implementation were compared.Results After the application of the one-hospital multi-campus difference management strategy,the overall medical experience score of the patients in the 3 campus was(58.54±2.36)points,which was higher than(58.13±3.24)points before the application(t=-3.223,P=0.001),and there was no statistically significant differences among the patients in the 3 campuses(F=0.781,P=0.458).After the application of the management strategy,the overall satisfaction score of the patients in the 3 campus was(98.44±6.22)points,which was higher than(97.98±6.87)points before the application of the management strategy(t=-2.490,P=0.013),and there was no statistical significance among the patients in the 3 campus(F=1.128,P=0.324).The number of banners and letters of commendation received by the 3 campuses increased from 1 661 before the application to 2 190 after the application,with a growth rate of 31.85％.Conclusion Differentiated management in a multi-campus hospital,aiming at homogenized quality through differentiated strategies,is practicable and can significantly improve the patient experience and satisfaction across different campuses.
