OBJECTIVE To investigate the application and influencing factors of sodium-dependent glucose transporters 2 inhibitors（SGLT-2i） in patients with heart failure with preserved ejection fraction（HFpEF） in the real world. METHODS Data from 358 patients with HFpEF who were hospitalized at the First Affiliated Hospital of Chongqing Medical University from May 2023 to May 2024 were retrospectively collected. The patients were divided into the SGLT-2i group and the non-SGLT-2i group based on whether they were prescribed SGLT-2i upon discharge. Baseline characteristics， comorbidities， and differences in drug treatment were compared between the two groups. Based on univariate analysis， multivariate Logistic regression analysis was performed to identify independent influencing factors of SGLT-2i use in patients with HFpEF， followed by further stratified analysis. RESULTS Among 358 HFpEF patients， the overall utilization rate of SGLT-2i was 33.5%. Combined with type 2 diabetes [OR＝9.063，95%CI（4.924-16.679） ] ， atrial fibrillation [OR＝3.135，95%CI（1.590-6.178） ] ， coronary artery heart disease [OR＝1.888，95%CI（1.072-3.327） ] and the use of loop diuretics [OR＝3.822， 95%CI （1.588-9.200） ] were all independent influencing factors for the use of SGLT-2i in patients with HFpEF （ P ＜0.05）. The results of the stratified descriptive analysis were consistent with those of the multivariate analysis， showing a higher utilization rate of SGLT-2i among patients with concomitant T2DM，atrial fibrillation， coronary artery heart disease， and those receiving loop diuretics （ P ＜0.05）； whereas the utilization rate of SGLT-2i was comparable across patients with different levels of renal function （ P ＞0.05）. CONCLUSIONS In the real-world clinical practice， the utilization of SGLT-2i in patients with HFpEF remains suboptimal， and treatment coverage still needs to be improved. Their use of SGLT-2i is primarily influenced by the presence of type 2 diabetes， atrial fibrillation， coronary artery heart disease， and the use of loop diuretics.

Objective: To investigate the protective effects of Gouqizi (Lycii Fructus, GQZ)-Danshen (Salviae Miltiorrhizae Radix et Rhizoma, DS) against hydrogen peroxide (H2O2)-induced oxidative injury in 661W retinal photoreceptor cells and to explore whether these effects involve angiopoietin-like 4 (ANGPTL4). Methods: Liquid chromatography-mass spectrometry (LC-MS) was used to identify the major components of GQZ-DS aqueous extract. An H2O2-induced oxidative injury model was established in 661W cells. Working concentrations of H2O2 and GQZ-DS were determined using the cell counting kit-8 (CCK-8) assay. Cells were subjected to GQZ-DS, ANGPTL4 knockdown, or ANGPTL4 overexpression as indicated. Flow cytometry was used to analyze cell cycle distribution, apoptotic rate, and intracellular reactive oxygen species (ROS). Colorimetric determination of malondialdehyde (MDA) content and superoxide dismutase (SOD) activity using the thiobarbituric acid (TBA) method was performed. The protein expression level of ANGPTL4 was assessed by immunofluorescence. Reverse transcription-quantitative polymerase chain reaction (RT-qPCR) was performed to quantify the mRNA level of ANGPTL4. Western blot was used to detect the protein levels of ANGPTL4 and cleaved caspase-3. Results: LC-MS identified five major constituents in the GQZ-DS aqueous extract: 2-O-β-D-glucopyranosyl-L-ascorbic acid, rutin, D-galactose, salvianolic acid A, and tanshinone IIA. The CCK-8 method selected 300 μmol/L H2O2 as the oxidative stress condition for experiments, and 0.05 and 0.1 g/mL were selected as the low and high doses of GQZ-DS, respectively, for subsequent experiments. The intervention with H2O2 resulted in reduced cell viability, elevated ROS and MDA levels, decreased SOD activity, increased apoptotic rate, upregulated cleaved caspase-3 expression, and G0/G1 phase cell cycle arrest of 661W cells. Both low and high doses of GQZ-DS alleviated these alterations, with high dose exhibiting stronger protective effects (P < 0.05 or P < 0.01). GQZ-DS also downregulated ANGPTL4 expression at both the mRNA and protein levels. Following plasmid transfection of cells, the study further revealed that ANGPTL4 knockdown mitigated oxidative stress and apoptosis-related injury, whereas ANGPTL4 overexpression exacerbated these pathological changes. Moreover, GQZ-DS partially reversed the degree of cellular oxidative damage induced by ANGPTL4 overexpression. Conclusion GQZ-DS can alleviate the H2O2-induced oxidative injury of 661W retinal photoreceptor cells, and the effects are related to the down-regulation of ANGPTL4 expression.

Large language models (LLMs) offer a modern approach to help inherit traditional Chinese medicine (TCM). This article discussed the progress of LLM applications in TCM and proposed future development directions by reviewing the existing research. We have found that LLMs and related technologies have excellent applications and performance in the management of TCM knowledge and data. They are often applied in information extraction, knowledge graph construction, and data standardization processing. However, data quality and security issues need to be given more attention. In clinical diagnosis and treatment, LLMs can imitate the thinking of TCM by disassembling and reconstructing its diagnostic process and can achieve functions such as prescription recommendation and question and answer (Q&A). However, this approach involves LLMs making inferences and predictions based on existing corpora and thus may not flexibly handle complex environments and tasks. Moreover, the current evaluation criteria for TCM LLMs can be summarized into 3 categories: general evaluation metrics, technical framework evaluation, and evaluation criteria for the characteristics of TCM (such as consistency rates of prescriptions and diagnostic suggestions). However, the lack of a unified and standardized evaluation system hinders the clinical application of TCM LLMs. The future progress of TCM LLMs should focus on the 3 aforementioned critical aspects to achieve technological breakthroughs. In addition, we are promoting the research on vertical TCM LLMs and application terminals. We believe this will bring new ideas to the research on TCM LLMs.

Objective To understand the mortality and potential life loss due to coronary heart disease (CHD) and stroke in Wujiang District, Suzhou from 2011 to 2022, and to provide strategies and basis for the prevention and treatment of CHD and stroke. Methods We collected the data of death cases due to CHD and stroke from the death monitoring system in Suzhou from 2011 to 2022. The mortality of CHD and stroke, potential years of life lost (potential years of life lost , PYLL), average years of life lost (average years of life lost , AYLL) and potential years of life lost rate (potential years of life lost rate , PYLLR) were calculated to analyze the development trend of death and disease burden of CHD and stroke. Results From 2011 to 2022, the crude mortality of CHD was 31.91/10 million, and that of stroke was 118.93/10 million. CHD and stroke mortality rates both showed an upward trend（P＜0.05, a statistically significant trend）. From 2011 to 2022, the mortality rate of CHD and stroke in Wujiang District increased rapidly with the increase of age. From 2011 to 2022, the disease burden caused by CHD totaled 11005 person-years, with PYLLR of 1.26% and AYLL of 12.34 years per person. The PYLL caused by stroke was 13 587.5 people-years, the PYLLR was 1.55%, and the AYLL was 8.93 years per person. PYLL, PYLLR and AYLL all decreased in women（P<0.05）, with no significant change in men（P>0.05）. Conclusion From 2011 to 2022, the mortality rate of CHD and stroke in Wujiang District appeared a tendency towards a rise, effective intervention and prevention measures should be taken among elderly and male residents.

Gouty arthritis （GA） is an inflammatory disorder caused by monosodium urate （MSU） crystal deposition， accompanied by elevated oxidative stress and aberrant release of inflammatory cytokines， resulting in joint tissue damage and intense pain. Nuclear factor E₂-related factor 2 （Nrf2）， a key transcription factor regulating the antioxidant defence system， exerts cytoprotective effects through dissociation from Kelch-like ECH-associated protein 1 （Keap1） and activates downstream antioxidant response element （ARE）-mediated pathways. It can upregulate the expression of heme oxygenase-1 （HO-1）， NADH quinone oxidoreductase 1 （NQO1）， superoxide dismutase （SOD）， and glutathione transferase （GST） to preserve redox homeostasis. Moreover， Nrf2 can suppress activation of NOD-like receptor protein 3 （NLRP3） inflammasomes， reduce pro-inflammatory cytokine production and release， modulate nuclear factor-κB （NF-κB） transcriptional activity， regulate gut microbiota balance， enhance mitophagy， and inhibit apoptosis， so as to reduce joint inflammation and pain and promote body recovery. This review systematically examined recent advancements in traditional Chinese medicine （TCM） for GA prevention and treatment via regulating the Nrf2 signaling pathway. It delineated Nrf2's molecular mechanisms and its role in GA pathogenesis and elucidated how TCM intervenes in multiple pathways including Keap1/Nrf2/ARE， Nrf2/HO-1（NQO1）， and Nrf2/NF-κB/NLRP3 to exert therapeutic effects. The study demonstrated that TCM monomers and compounds effectively counteract oxidative damage， attenuate inflammatory responses， promote autophagy， and inhibit apoptosis via regulating the Nrf2 signaling pathway. These findings not only clarify the scientific basis of TCM in GA treatment but also offer strategic insights for developing novel Nrf2-targeted anti-gout drugs.

Objectives:This study aims to explore the relationship between the pericoronary fat attenuation index(FAI)and triglyceride-glucose(TyG)index and atrial fibrillation recurrence after radiofrequency catheter ablation(RFCA)in patients with atrial fibrillation(AF).Methods:This retrospective study enrolled consecutive AF patients who underwent their first successful RFCA at the Affiliated Hospital of Xuzhou Medical University from 2019 to 2023.Pericoronary FAI was quantitatively measured,and the TyG index was calculated.Patients were divided into three groups according to the TyG index quartile:T1 group(TyG index<8.45,n=114);T2 group(8.45≤TyG index≤8.93,n=114);T3 group(TyG index>8.93,n=120).Linear regression was used to analyze the correlation between the TyG index and proximal FAI of three coronary arteries.Logistic regression was employed to explore the correlation between pericoronary FAI,TyG index,and AF recurrence post-RFCA,restrictive cubic splines(RCS)were plotted.Additive interaction and mediation analyses were used to explore the role of pericoronary FAI in the relationship between the TyG index and post-RFCA AF recurrence.Subgroup analysis was performed to explore the predictive value of the TyG index for postoperative recurrence in different patient subgroups.Results:A total of 348 patients were included.After adjusting for confounding factors using linear regression analysis,each unit increase in the TyG index was associated with a 5.389 HU increase in left circumfleex artery(LCX-FAI)(95%CI:3.874-6.904,P<0.001).During one-year follow-up,90 cases(25.86%)experienced AF recurrence.RCS analysis indicated that there was no significant nonlinear relationship between LCX-FAI,TyG index,and AF recurrence after RFCA(Pnon-linear=0.378,Pnon-linear=0.469).The recurrence rate of AF in patients with TyG index>9.08 and LCX-FAI>-83.65 HU was about 57.737 times higher than those with TyG index≤9.08 and LCX-FAI≤-83.65 HU(OR=57.737,95%CI:23.755-155.656,P<0.001).There was an additive interaction between the TyG index and LCX-FAI:relative excess risk due to interaction(RERI)was 50.901(95%CI:0.215-101.587),attributable proportion due to interaction(AP)was 0.882(95%CI:0.769-0.994),and the synergy index(S)was 9.713(95%CI:3.380-27.910).Mediation analysis indicated that LCX-FAI mediated 22%of the relationship between the TyG index and AF recurrence.Subgroup analysis revealed no multiplicative interaction between the type of atrial fibrillation and the TyG index in terms of AF recurrence risk(Pinteraction=0.562).Conclusions:In patients with atrial fibrillation,the TyG index is positively correlated with LCX-FAI,patients with TyG index>9.08 and LCX-FAI>-83.65 HU have significantly increased risk of AF recurrence after RFCA.LCX-FAI partially mediates the relationship between the TyG index and post-RFCA recurrence.Furthermore,the TyG index can effectively predict AF recurrence in both persistent and paroxysmal atrial fibrillation patients.

Objective To explore the causal relationship between breast cancer and free fatty acid receptor 4(FFAR4)by using two-sample Mendelian randomization.Methods By using Genome-wide Association Studies and expression quantitative trait locus(eQTL)data,single nucleotide polymorphism sites closely related to breast cancer and FFAR4 were extracted.Causal effect values were calculated by using five methods:inverse variance weighting(IVW),MR-Egger,weighted median,simple mode and weighted mode.Cochran Q tests were used to detect heterogeneity,MR-Egger intercept tests and MR-PRESSO tests were used to assess level multiplicity,and the hold-out method was employed for sensitivity analysis to ensure robustness of the results.Additionally,Bayesian co-location analysis was used to evaluate whether FFAR4 expression shares the same causal genetic variant with breast cancer in given genomic region.Results A total of 12 eQTLs closely related to FFAR4 expression levels were included in this study.The results of IVW analysis showed that increased FFAR4 expression levels increased the risk of overall breast cancer,Luminal A,Luminal B/HER2-negative,and HER2-enhanced subtypes of breast cancer.The co-location analysis showed that the posterior probability of FFAR4 expression level and total breast cancer shared causal variation was 0.889.Conclusion There may be a causal relationship between FFAR4 expression and breast cancer.

[Purpose]To analyze the trends of disease burden for lung cancer worldwide and in China from 1990 to 2021.[Methods]Data of the disease burden of lung cancer and population demographics in 1990 and 2021 stratified by sex and age groups for global,five SDI quintiles re-gions,and eight countries including China,Japan,Republic of Korea,United Kingdom,France,United States,Canada,and Australia were extracted from the Global Burden of Disease Study 2021(GBD 2021)database.The age-standardized mortality rate(ASMR)and age-standard-ized disability-adjusted life year rate(ASDR)of lung cancer attributable to 7 level-3 risk factors in China for 1990 and 2021 were also extracted.Counterfactual analysis was used to decompose changes in lung cancer deaths and DALY from 1990 to 2021 into four contributing factors:popu-lation size,population structure,age-standardized incidence or prevalence,and lung cancer case fatality or disease severity.The percentage changes in lung cancer deaths and DALY attributed to these four factors were calculated respectively.[Results]In 2021,there were 934 704 new cases and 814 364 deaths of lung cancer in China.From 1990 to 2021,the incidence,preva-lence,mortality,and DALY rates of lung cancer in China increased faster than those worldwide and in high-middle SDI regions,which was similar to Japan and Republic of Korea.In contrast,the mortality rates of lung cancer decreased in United States and United Kingdom;and the DALY rates of lung cancer decreased in United States,United Kingdom,Canada and Australia.From 1990 to 2021,the age-related lung cancer deaths and DALY in China increased by 193.91％and 146.20％,respectively.The primary contributor to the increase in lung cancer deaths was population aging(102.82％)among men and rising age-standardized incidence(119.00％)among women,while the primary contributor to the increase in DALY was rising age-standardized prevalence for both men(153.12％)and women(218.77％).In 2021,the top three risk factors contributing to lung cancer ASMR and ASDR in China were smoking,particulate matter pollution and occupational carcinogen exposure.Compared with 1990,the ASMR of lung cancer and its proportion at-tributable to particulate matter pollution and low dietary fruits were decreased,while the propor-tions in ASDR of lung cancer attributable to smoking and secondhand smoke increased.[Conclu-sion]Lung cancer is a major public health challenge in China.Compared with worldwide,high-middle SDI regions and certain developed countries,China has experienced faster growth in the incidence,prevalence,mortality and DALY of lung cancer,especially among women.To reduce disease burden,sustained efforts on lung cancer prevention and control are urgently required in China.
