Objective To investigate the characteristic distribution of traditional Chinese medicine(TCM)syndrome types in gouty arthritis patients complicated with bone erosion,and to analyze the associated factors.Methods A total of 318 gouty arthritis patients hospitalized in the Rheumatology and Immunology Department of Foshan Hospital of Traditional Chinese Medicine between November 2021 and November 2023 were included.The patients were allocated to a bone erosion group(142 cases)and a non-bone erosion group(176 cases)according to the findings of musculoskeletal ultrasound.The clinical data of gender,age,body height,body mass,body mass index(BMI),systolic blood pressure(SBP),diastolic blood pressure(DBP),course of gout,findings of musculoskeletal ultrasound,complete blood count[white blood cell count(WBC),platelet count(PLT),hemoglobin(Hb),and red blood cell count(RBC)],blood uric acid(UA),creatinine(Cr),erythrocyte sedimentation rate(ESR),C-reactive protein(CRP),total cholesterol(TC),and low-density lipoprotein cholesterol(LDL-C)of the patients during hospitalization were collected.Differences in general information,laboratory parameters,and distribution of TCM syndrome types were compared between the two groups,and then the potential influencing factors of bone erosion in gouty arthritis patients were explored.Results(1)Analysis of general information showed that the bone erosion group had longer course of gout and slightly lower BMI than that the non-bone erosion group,and the differences were statistically significant(P＜0.05 or P＜0.01).However,there were no statistically significant differences in age,body height,body mass,SBP and DBP among the patients of the two groups(P>0.05).(2)Analysis of laboratory indicators showed that the levels of Cr,UA,ESR and TC in the bone erosion group were significantly higher than those in the non-bone erosion group,and the differences were statistically significant(P＜0.05 or P＜0.01).However,no statistically significant differences in the levels of CRP,WBC,RBC,PLT and LDL-C were presented between the two groups(P＞0.05).(3)Analysis of the distribution of TCM syndromes showed that in the bone erosion group,stagnant-heat obstruction syndrome accounted for the largest proportion(33.10%),followed by phlegm-turbidity obstruction syndrome(29.58%),damp-heat accumulation syndrome(22.54%),and liver-kidney yin deficiency syndrome(14.79%);in the non-bone erosion group,damp-heat accumulation syndrome accounted for the largest proportion(38.07%),followed by liver-kidney yin deficiency syndrome(32.95%),phlegm-turbidity obstruction(14.77%),and stagnant-heat obstruction(14.20%).There was statistically significant difference in the distribution of TCM syndromes between the two groups(P＜0.01).(4)The results of logistic regression analysis suggested that the higher the levels of ESR,UA,and TC,the longer the course of gout.And the TCM syndromes of stagnant-heat obstruction and phlegm-heat obstruction were the risk factors for bone erosion in gouty arthritis(P＜0.05 or P＜0.01).Conclusion Gouty arthritis patients with bone erosion exhibit higher UA,ESR,Cr,and TC levels,longer course of disease,and higher incidence of stagnant-heat obstruction syndrome and phlegm-turbidity obstruction syndrome.Bone erosion in gouty arthritis is closely associated with elevated UA,ESR,TC,and some specific TCM syndrome patterns.

Objective:Drawing upon behavioral economics theory,it aims to elucidate the irrational decision-making mechanisms and systematic governance strategies driving low-value care in oncology,optimize healthcare resource allocation and enhance service quality.Methods:Centered on the dual-system theory framework,the behavioral economics principles of loss aversion,anchoring effects,and intertemporal choice are integrated to develop a physician-patient shared decision-making model spanning the entire cancer care continuum(screening,diagnosis,treatment,rehabilitation).Results:Low-value oncology care are jointly driven by physicians' defensive psychology,patients'loss aversion preferences,and socio-cultural pressures.Conclusion:Multidimensional interventions,such as predefining high-value care pathways,establishing negative lists to constrain low-value supply,reforming payment mechanisms,and implementing targeted health education,can effectively disrupt the"cognitivebias-behavioral inertia"loop and improve the efficiency of resource allocation in cancer diagnosis and treatment.

Objective To investigate the association between gout-related gene polymorphisms and clinical phenotypic heterogeneity among gout patients in the Foshan region,thereby providing a scientific basis for stratified clinical management.Methods A total of 125 gout patients diagnosed at the Foshan Hospital of Traditional Chinese Medicine between June 2022 and May 2025 were enrolled in this study.The collected data included demo-graphic characteristics,frequency of gout attacks,presence of tophi,levels of uric acid,creatinine,C-reactive protein(CRP),erythrocyte sedimentation rate(ESR),gout-related genes(ABCG2,SLC2A9,SLC22A12,MTHFR),and joint ultrasound findings.Group comparisons and rank correlation analyses were conducted to explore potential associations between gene polymorphisms and clinical heterogeneity.Results The male-to-female ratio was 11∶1;the mean age was(35.28±2.67)years;the mean disease duration was(6.03±0.68)years;and the mean frequency of acute attacks in the past 12 months was 4(2.0,7.25).Genotype distributions were as follows:ABCG2:wild-type(C/C),23.8%;heterozygous(C/A),53.2%;homozygous(A/A),23%.SLC2A9:wild-type(A/A),24.6%;heterozygous(A/G),50%;homozygous(G/G),25.4%.SLC22A12:wild-type(A/A),4.8%;heterozygous(A/C),31.7%;homozygous(C/C),63.5%.MTHFR:wild-type(C/C),68.3%;heterozygous(C/T),28.6%;homozygous(T/T),3.2%.Rank correlation analysis revealed that SLC2A9 polymorphisms were significantly correlated with tophi formation(ρ=0.193,P=0.031)and crystal deposition on ultrasound(ρ=0.202,P=0.025).SLC22A12 polymorphisms were associated with hypertension(ρ=0.269,P=0.003)and diabetes(ρ=0.200,P=0.026).MTHFR polymorphisms showed a correlation with diabetes(ρ=0.224,P=0.012).Conclusions Polymorphisms in SLC2A9,SLC22A12,and MTHFR are significantly linked to clinical phenotypic heterogeneity among gout patients.Genetic testing could facilitate the early identification of individuals at high risk for complications and support the development of stratified and individualized treatment approaches.

Objective To explore the identification method,pathogenesis,clinical characteristics and individualized pharmacotherapy of asymptomatic hyperuricemia after renal transplantation.Methods The pharmacist was on duty at the organ transplant outpatient clinic.During this time,they analyzed and sorted out the medications,identified and differentiated a case of asymptomatic hyperuricemia related to spironolactone in a patient who had undergone a renal transplant,and provided comprehensive care throughout the entire process.Results The asymptomatic hyperuricemia in this patient might be associated with spironolactone,and the adverse reactions of the patient were alleviated by pharmacists through optimizing clinical treatment.Up to now,no hyperuricemia occurred.Conclusions Pharmacists are required to collaborate closely with clinicians to establish medication profiles for patients under long-term follow-up and to closely monitor and evaluate drug-related adverse reactions.Additionally,they should assess the renal function and immune status of transplant recipients promptly and formulate individualized treatment plans in order to enhance the long-term survival of both the transplanted kidneys and the recipients.

Objective:To establish a new method and platform for screening, identifying, and exploring a new strategy for anti-hepatitis B immunotherapy based on hepatitis B virus (HBV)-specific TCR.Methods:Peripheral blood mononuclear cells were isolated from patients with acute hepatitis B. CD3 +CD8 +CD137 +T single cells were sorted out after stimulation with the HBsAg peptide library. The α and β chains in TCRs of single cells were amplified by PCR. TCR double-chain pairing and lentiviral packaging were performed through high-throughput sequencing. Re-infected Jurkat-76-NFAT-GFP cells and the cell lines stably expressing TCR were screened. HBsAg peptide library and immortalized B lymphocytes co-cultured with J76N-TCR were used to screen HBsAg-specific TCRs. K562 cell lines stably expressing HLA-A*24:02 were established to determine epitope peptide by screening A*24:02-restricted TCR. The screened TCRs were replaced with mouse C regions and packaged with lentiviruses. Functional validation was performed on healthy human CD4 +T and CD8 +T lymphocytes following infection. Results:Stable TCR-expressing cell lines were successfully prepared based on single-cell TCRαβ double-chain amplification and pairing technology. Twenty-one TCRs were screened using immortalized B lymphocytes, resulting in nine possible HLA-A*24:02-restricted HBsAg-specific TCRs. Further screening with K562-A2402 resulted in six A*24:02-restricted HBsAg-specific TCRs with identically recognized epitope peptide. The functional determination of the two TCR clones revealed their specific recognition function for target cells expressing HBsAg.Conclusion:HLA-A*24:02-restricted HBsAg-specific TCR with recognition function for target cells expressing HBsAg was successfully obtained based on the new experimental technology system, laying an important foundation for further exploration of antiviral immunotherapy based on HBV-specific TCR.

Objective:To explore the abnormal patterns of brain functional network connectivity in depression adolescents and their diagnostic value in adolescent depression.Methods:A total of 94 depression adolescents (adolescent depression group) admitted to Outpatient Department of Psychiatric Imaging, West China Hospital, Sichuan University from January 2020 to December 2022 were selected. In addition, 78 age- and gender-matched healthy adolescents were recruited from local community advertisements at the same time-period as healthy control group. Resting-state functional magnetic resonance imaging was performed; after image preprocessing, group-level spatial independent component analysis was performed to identify the intrinsic network connectivity, and differences in network connectivity between the two groups were compared. Functional connectivity edges were employed as classification features, and feature ranking and screening were then performed. A support vector machine (SVM) with linear kernel function was used to construct a classification model, and receiver operating characteristic (ROC) curve was used to analyze the diagnostic value of this classification model in adolescent depression.Results:No significant difference was noted in age, gender, years of education, and body mass index between the two groups ( P>0.05). Compared with the healthy control group, the adolescent depression group had significantly decreased functional connectivity intensity within and between the networks of sensorimotor network (SMN), visual network (VN), auditory network (AN), default mode network (DMN), and cognitive control network (CCN), and significantly increased functional connectivity intensity within CCN ( P<0.05). When using the 75 top-ranked functional connectivity features, this classification model had the best performance (accuracy rate: 70.35%, sensitivity: 70.21%, specificity: 71.80%, P<0.001). ROC curve showed that area under the curve of this classification model in diagnosing adolescent depression was 0.724 (95% CI: 0.648-0.800, P<0.001). A total of 51 consistent functional connectivities were identified and they were mainly located within or between the networks of SMN, VN, AN, DMN, and CCN. Conclusion:The abnormal resting-state brain functional connectivity in depression adolescents can provide imaging basis for their clinical diagnosis.
