Background The global prevalence of obesity is on the rise and is closely associated with various chronic non-communicable diseases such as cardiovascular diseases and diabetes. There is a relative lack of long-term dynamic studies on compound obesity among occupational populations. Objective To explore the changing trends of compound obesity among different occupational groups aged 18–59 years in nine provinces (autonomous regions, municipalities) of China from 1993 to 2018, and to provide a scientific basis for formulating targeted weight management strategies for occupational populations. Methods A total of 34519 employed adults aged 18–59 years from nine waves of the China Health and Nutrition Survey in1993, 1997, 2000, 2004, 2006, 2009, 2011, 2015, and 2018 were included. Obesity types were determined according to the Chinese Adult Weight Management Guidelines. The Joinpoint regression model was used to calculate the average annual percentage change (AAPC) and annual percentage change (APC) of compound obesity rates. Results From 1993 to 2018, the age-standardized compound obesity rate among the occupational population aged 18–59 years showed an upward trend (AAPC=6.24%, 95%CI: 5.09%, 7.41%, P<0.05). The AAPCs (95%CI) for age-standardized compound obesity rates among agricultural workers, blue-collar workers, other occupational groups, service workers, and white-collar workers were 9.55% (7.51%, 11.64%), 6.18% (4.70%, 7.69%), 5.53% (2.27%, 8.90%), 4.07% (2.40%, 5.77%), and 3.89% (2.16%, 5.65%), respectively, with statistically significant differences (P<0.05). Among males, the AAPCs (95%CI) for age-standardized compound obesity rates among agricultural workers, blue-collar workers, other occupational groups, service workers, and white-collar workers were 11.52% (7.71%, 15.47%), 7.28% (6.18%, 8.40%), 5.92% (2.28%, 9.69%), 5.56% (2.11%, 9.12%), and 4.22% (2.33%, 6.15%), respectively, with statistically significant differences (P<0.05). Among females, the AAPCs (95%CI) for age-standardized compound obesity rates among agricultural workers, blue-collar workers, and white-collar workers were 7.45% (6.22%, 8.69%), 3.72% (0.84%, 6.67%), and 2.41% (0.17%, 4.70%), respectively, with statistically significant differences (P<0.05). A turning point was observed in the compound obesity rate among female white-collar workers in 2006, with an APC (95%CI) of 9.69% (5.24%, 14.33%) from 2006 to 2008, showing a statistically significant difference (P<0.05), while no significant trend was found from 1993 to 2006 (P>0.05). No significant trends were observed in the age-standardized compound obesity rates among females in other occupational groups and service workers (P>0.05). Conclusion The compound obesity rate among China's occupational population is increasing rapidly, with the growth rate among agricultural workers being particularly prominent. In 2018, male white-collar workers and female agricultural workers exhibit relatively high compound obesity rates, warranting focused attention. Although the overall growth rate among service workers is slower, the expanding workforce in this sector indicates that obesity remains a serious issue. Targeted occupational health and weight management interventions are needed in the future.

This paper outlines the development of artificial intelligence （AI） and its applications in traditional Chinese medicine （TCM） research， and elucidates the roles and advantages of large language models， knowledge graphs， and natural language processing in advancing syndrome identification， prescription generation， and mechanism exploration. Using spleen-stomach diseases as an example， it demonstrates the empowering effects of AI in classical literature mining， precise clinical syndrome differentiation， efficacy and safety prediction， and intelligent education， highlighting an upgraded research paradigm that evolves from data-driven and knowledge-driven approaches to intelligence-driven models. To address challenges related to privacy protection and regulatory compliance in cross-institutional data collaboration， a "trusted federated evidence-based analysis platform for TCM spleen-stomach diseases" is proposed， integrating blockchain-based smart contracts， federated learning， and secure multi-party computation. The deep integration of AI with privacy-preserving computing is reshaping research and clinical practice in TCM spleen-stomach diseases， providing feasible pathways and a technical framework for building a high-quality， trustworthy TCM big-data ecosystem and achieving precision syndrome differentiation.

AIM: To explore the factors influencing the efficacy of diabetic macular edema(DME)with conbercept and to construct a nomogram prediction model. METHODS:Retrospective analysis. Patients with DME admitted from January 2021 to October 2025 were selected. All patients received intravitreal conbercept injection once monthly for three consecutive months. Subjects were divided into a good response group and a poor response group according to the reduction in central macular thickness(CMT)at 3 mo after treatment. The clinical data of the patients were collected to analyze factors associated with poor response to conbercept therapy in patients with DME, and to construct a nomogram prediction model for identifying poor responders to conbercept treatment among DME patients.RESULTS:A total of 400 DME patients(400 eyes)were included in this study. The response group consisted of 312 patients(312 eyes), with 200 males and 112 females, with an average age of 64.85±5.13 y. The non-response group consisted of 88 patients(88 eyes), with 54 males and 34 females, with an average age of 65.14±4.93 y. There were no differences between the two groups in terms of gender, age, alcohol consumption, smoking status, duration of diabetes, edema classification, disease classification, low-density lipoprotein, HRF, ELM and/or EZ continuity interruption, and SRF(all P>0.05). However, there were differences in DR disease duration, pre-treatment BCVA, high-density lipoprotein, glycated hemoglobin, DRIL, and VMIA(all P<0.05). Multivariate Logistic regression analysis showed that DR disease duration ≥1 y(OR=2.351, 95%CI: 1.360-4.065), poor pre-treatment BCVA(OR=3.432, 95%CI: 1.581-6.988), high glycated hemoglobin(OR=1.656, 95%CI: 1.346-2.038), presence of DRIL(OR=3.115, 95%CI: 1.532-6.333), and presence of VMIA(OR=2.526, 95%CI: 1.445-4.415)were all risk factors for poor response to conbercept treatment in DME patients, while elevated high-density lipoprotein(OR=0.025, 95%CI: 0.004-0.163)was a protective factor for poor response to conbercept treatment in DME patients(P<0.05). ROC analysis showed that the area under the curve(AUC)of the nomogram model for predicting poor response to conbercept treatment in DME patients was 0.817(95%CI: 0.776-0.854), with a sensitivity of 73.86% and a specificity of 78.21%. When the threshold probability was >3%, the nomogram model for predicting poor response to conbercept treatment in DME patients was more favorable for all patient treatment plans. CONCLUSION:The nomogram prediction model constructed in this study is helpful for the clinical early identification of patients with DME who have a high risk of poor response to conbercept treatment, and can provide a reference for the early prevention of poor response to conbercept treatment.

Objective:To investigate the effect of donor blood lipid levels and the degree of fat deposition on the pancreatic surface on the outcome of islet isolation.Method:A retrospective analysis was conducted on 171 cases of islet isolation data from organ donors between May 2015 and December 2024. According to the percentage of fat deposition area on the surface of the pancreatic capsule after trimming, the samples were divided into three groups: mild surface fat group (<30%, 60 cases) , moderate surface fat group (30%–70%, 55 cases) , and severe surface fat group (>70%, 56 cases). The modified Ricordi method was used to digest pancreatic tissue, and islets were purified by continuous density gradient centrifugation. The digestion efficiency, digestion time, islet yield (islet equivalent/quantity) , purity, score, and size were analyzed and compared among groups. One-way ANOVA was used for inter-group comparisons, and Pearson correlation analysis and multiple linear regression analysis were used to explore the relationship between blood lipid levels and islet isolation parameters.Result:The severe surface fat group had significantly higher pre-purification and post-purification islet equivalents, islet number, amount of digested pancreatic tissue, donor triglyceride levels, and low density lipoprotein (LDL) levels than the other groups (all P<0. 05) . Correlation analysis showed that LDL level was positively correlated with pre-purification islet equivalents (62 cases, r=0. 298, P=0. 019) and islet number (58 cases, r=0. 285, P=0. 030) . Donor high density lipoprotein (HDL) level was negatively correlated with post-purification islet equivalents (54 cases, r= – 0. 282, P=0. 039) ; donor triglyceride level was positively correlated with the amount of digested tissue (56 cases, r=0. 268, P=0. 046) and negatively correlated with purity (51 cases, r= - 0. 297, P=0. 035) ; donor very low density lipoprotein (VLDL) level was positively correlated with the amount of digested tissue (67 cases, r=0. 337, P=0. 005) and negatively correlated with purity (61 cases, r=- 0. 348 , P=0. 006) ; donor total cholesterol level was negatively correlated with pancreatic digestion efficiency (34 cases, r= - 0. 370, P=0. 032) , and the above differences were all statistically significant. Conclusion:Pancreata with heavier surface fat deposition can yield a higher number of islets. Meanwhile, donor blood lipid levels are correlated with islet isolation outcomes and can serve as important indicators for donor pancreas selection.

Purpose To investigate the role of ultrasound-guided fine needle aspiration cytology(US-FNAC)in the diagnosis of breast cancer.Methods Fine needle aspiration cytology(FNAC)samples of 203 patients with breast cancer were selected and prepared by liquid-based cytology.The results of histopathology after neoadjuvant therapy were used as the gold standard to compare with the diagnostic results of FNAC samples,and then evaluated the diagnos-tic coincidence rate of FNAC samples.Results Of 203 axillary lymph node FNAC samples,111 cases were diagnosed as positive,38 cases were diagnosed as suspicious for positivity,and 54 cases were diagnosed as negative.The diag-nostic accuracy of FNAC was 85.2％,the sensitivity of FNAC was 98.0％,and the specificity of FNAC was 90.0％.Conclusion FNAC has high sensitivity and accuracy in the diagnosis of axillary lymph node metastasis.Sentinel lymph node biopsy is recommended for patients with negative FNAC but clinically and radiographically suspected lymph node metastasis.

Objective:To explore the role of LncRNA NKILA/NF-κB signal pathway in the injury of keratinocytes in oral lichen planus(OLP).Methods:Immortalized human epidermal cells(HaCaTs)were induced by bacterial lipopolysaccharide(LPS)to establish an in vitro cell model of OLP.HaCaTs stably overexpressing NKILA were constructed by lentivirus method.HaCaTs were divided into 4 groups:Control group,Control+LPS group,empty vector infected with lentivirus(NC)+LPS group,overexpressed NKILA(OE)+LPS group.Cell proliferation,apoptosis,total superoxide dismutase(SOD)activity,lipid malondialdehyde oxide(MDA),reactive oxygen species(ROS),expression of related inflammatory factors,p65(nuclear,mass)and NF-κB signaling pathway related protein expression and p65 expression and localization were respectively detected.Results:Compared with Control group,the expression of NKILA,cell proliferation activity and SOD enzyme activity in Control+LPS group were significantly de-creased,while the apoptosis rate,MDA,ROS,IL-6,IL-1β,TNF-α and p65(nuclear and plasma)expression levels were signifi-cantly up-regulated(P＜0.05).Compared with Control+LPS group,the cell proliferation activity and SOD activity were increased in OE+LPS group,and the expression levels of cell apoptosis,MDA,ROS,IL-6,IL-1β,TNF-α and p65(nuclear and plasma)were significantly decreased(P＜0.05),and the localization of p65 protein in the nucleus was significantly decreased in OE+LPS group.Conclusion:LncRNA NKILA may reduce the damage of keratinocytes in oral lichen planus by inhibiting NF-κB signal pathway.
