ObjectiveTo evaluate the comprehensive intervention effects of Huangqin Qingre Chubi Capsule （黄芩清热除痹胶囊， HQC） on self-perception of patients （SPP） and immune inflammation in patients with rheumatoid arthritis （RA）， and to explore its potential mechanisms. MethodsClinical data of 452 RA patients were retrospectively collected. Patients were divided into a control group （274 cases）， treated with conventional western medicine， and an observation group （178 cases）， treated with HQC for at least 2 weeks in addition to conventional western medicine. The treatment duration was 2 weeks for both groups. Propensity score matching （PSM） was performed at a ratio of 1∶1 to match patients between groups. SPP including the Chinese version of the short form-36 health survey （SF-36）， self-rating anxiety scale （SAS）， self-rating depression scale （SDS）， visual analog scale （VAS）， and Chinese patient-reported index for rheumatoid arthritis （CPRI-RA）， as well as immune inflammatory indicators， including erythrocyte sedimentation rate （ESR）， high-sensitivity C-reactive protein （hs-CRP）， rheumatoid factor （RF）， anti-cyclic citrullinated peptide antibody （anti-CCP）， interleukin-6 （IL-6）， immunoglobulin A （IgA）， immunoglobulin G （IgG）， immunoglobulin M （IgM）， complement C3， and complement C4， were collected before and after treatment. Spearman correlation analysis was used to assess the relationships between SPP and immune inflammatory indicators. Logistic regression， association rule analysis， and mediation analysis were performed to evaluate the effects and potential pathways of HQC on SPP and immune inflammatory indicators. Network pharmacology was applied to identify the active components and core targets of HQC in the treatment of RA， followed by molecular docking verification. In cell experiments， cells were divided into normal group， model group， 20% medicated serum group， and 80 nmol/L control group. Human synovial fibroblasts （FLS） were cultured with complete medium in the normal group， while human rheumatoid arthritis fibroblast-like synoviocytes （RA-FLS） were cultured in the model group. In the 20% medicated serum group， RA-FLS were cultured with medium containing 20% HQC-medicated serum， and in the 80 nmol/L control group， RA-FLS were cultured with complete medium containing 80 nmol/L methotrexate suspension. After 48 h of culture， cell viability was detected by cell counting kit-8 （CCK-8） assay. Levels of interleukin-1β （IL-1β）， interleukin-6 （IL-6）， interleukin-8 （IL-8）， and interleukin-10 （IL-10） in the cell supernatant were measured by enzyme-linked immunosorbent assay （ELISA）. Protein levels of matrix metalloproteinase 9 （MMP9）， transcription factor AP-1 subunit （JUN）， vascular endothelial growth factor A （VEGFA）， and C-X-C motif chemokine ligand 8 （CXCL8） were detected by Western Blot， and cell migration ability was evaluated using Transwell assay. ResultsAfter PSM， 178 cases were included in each group. After treatment， SF-36 scores increased， while scores of SAS， SDS， VAS and CPRI-RA， levels of ESR， hs-CRP， IL-6， complement C3， and complement C4 levels decreased in both groups； IgG and IgM levels were also reduced in the observation group （P＜0.05）. Physical functioning （correlation coefficient -0.19， P＜0.05） and social functioning （correlation coefficient -0.18， P＜0.05） of SF-36 were negatively correlated with hs-CRP， while VAS score was positively correlated with hs-CRP （correlation coefficient 0.19， P＜0.05）. HQC showed high associations with improvements in multiple indicators of SPP and immune inflammatory， and acted as a protective factor for the improvement of several SPP； hs-CRP and ESR played partial mediating roles in the improvement of SPP induced by HQC （P＜0.05）. Network pharmacology analysis identified baicalein， quercetin， α1-sitosterol， β-sitosterol， stigmasterol， baicalin， and crocetin as the core active components， and JUN， IL-6， VEGFA， MMP9， IL-1β， and CXCL8 as the core targets. Molecular docking results showed strong binding affinities of quercetin with VEGFA， JUN， MMP9， IL-6， and IL-1β， of baicalin with VEGFA and MMP9， and of wogonin with CXCL8. Cell experiments demonstrated that HQC and methotrexate inhibited RA-FLS viability and migration， reduced levels of IL-1β， IL-6， and IL-8， decreased protein levels of MMP9， JUN， VEGFA， and CXCL8， and increased IL-10 levels （P＜0.05）. ConclusionHQC can improve SPP in RA by regulating immune inflammatory responses. Its mechanism may be related to multi-pathway and multi-target inhibition of synovial cell inflammation and migration.

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.

Driven by the widespread adoption of minimally invasive thoracic surgical techniques and the deepening integration of enhanced recovery after surgery (ERAS) protocols, evidence-based perioperative airway management has emerged as a pivotal determinant of surgical safety, pulmonary functional recovery, and long-term prognosis. Currently, substantial regional disparities in thoracic surgical expertise persist across China, manifesting as heterogeneity in preoperative assessment standardization, inconsistent airway preparation strategies, divergent approaches to complication prevention, and limited penetration of advanced anesthetic technologies. To promote the standardization of clinical practices in this domain among hospitals at all levels, a multidisciplinary expert consortium has initiated the development of the Chinese Guidelines for Perioperative Airway Management in Thoracic Surgery (2026 edition). This protocol systematically delineates the methodological framework and structural blueprint underpinning the guideline’s formulation. Compared to the 2020 edition, the updated guideline places specific emphasis on refining stratified criteria for preoperative cardiopulmonary reserve assessment, establishing standardized management pathways for non-intubated spontaneous-ventilation techniques, formulating individualized multimodal perioperative pulmonary rehabilitation regimens, and defining precise intervention workflows for persistent postoperative cough. Collectively, these measures aim to further reduce the baseline incidence of perioperative pulmonary complications and to provide robust support for the clinical translation of enhanced recovery principles within the field of thoracic surgery.

BackgroundPatients with bipolar disorder exhibit persistent cognitive impairment across multiple domains， including executive function， memory， and attention. Furthermore， those with mixed features tend to have a poorer prognosis. Currently， research evidence regarding the characteristics of cognitive function and event-related potential P300， as well as their correlation， in patients with depressive episodes of bipolar disorder with mixed features remains limited. ObjectiveTo explore the correlation between cognitive function and event-related potential P300 in patients with depressive episodes of bipolar disorder with mixed features， analyze the influencing factors of cognitive function， so as to provide references for the improvement of cognitive function in this subtype of patients. MethodsA total of 73 patients who met the diagnostic criteria for depressive episodes of bipolar disorder in the Diagnostic and Statistical Manual of Mental Disorders， fifth edition （DSM-5） were enrolled from the outpatient and inpatient departments of Tianjin Anding Hospital from November 2021 to April 2024. The Hamilton Depression Scale-17 item（HAMD-17） was used to assess the severity of depressive symptoms， and the Clinically Useful Depression Outcome Scale Supplemented with Questions for the DSM-5 Mixed Features Specifier （CUDOS-M） was used to evaluate whether patients presented with mixed features. Based on the CUDOS-M total scores， patients were divided into two groups： the mixed features group （n=34） and the non-mixed features group （n=39）. The MATRICS Consensus Cognitive Battery （MCCB） was used to assess cognitive function， and auditory event-related potential P300 testing was performed. Spearman correlation analysis was used to examine the correlations between P300 indicators and MCCB scores. Multiple linear regression analysis was conducted to investigate the influencing factors of cognitive function. ResultsPatients with depressive episodes of bipolar disorder with mixed features had a longer total illness duration than those without mixed features， and the difference was statistically significant （t=2.030， P<0.05）. Analysis of covariance showed that the MCCB scores for processing speed， attention/vigilance， and reasoning and problem solving were all lower in the mixed features group than those in the non-mixed features group （F=3.650， 3.520， 4.213， P<0.01）. However， no significant difference was found between the two groups in P300 latency or amplitude （P>0.05）. Correlation analysis revealed that the MCCB attention/vigilance score was negatively correlated with P300 latency in patients with depressive episodes of bipolar disorder with mixed features （r_s=-0.576， P<0.01）. Multiple linear regression analysis showed that， in the mixed features group， years of education positively predicted processing speed （β=0.378， P<0.05）， while P300 latency （β=-0.699， P<0.01） and age （β=-0.424， P<0.01） negatively predicted attention/vigilance function. ConclusionPatients with depressive episodes of bipolar disorder with mixed features have a longer illness duration and more severe impairment in three cognitive domains： processing speed， attention/vigilance， and reasoning and problem solving. P300 latency may be an influencing factor of attention/vigilance function in patients with depressive episodes of bipolar disorder with mixed features ［Funded by Tianjin Key Medical Discipline Construction Project （number， TJYXZDXK-3-015B）； Hospital-level Scientific Research Project of Tianjin Anding Hospital （number， ADYKHT2021010）］

Objective To analyze the effect of LINC00894 on the malignant biological behavior of liver cancer cells by regulating the microRNA(miR)-495-3p/RAS associated binding protein 23(Rab23)axis.Methods Cancer and adjacent tissues of 53 patients with liver cancer who undergoing surgery from January 2023 to November 2023 were collected.Real-time fluorescence quantitative polymerase chain reaction(qRT-PCR)was used to detect the expression of LINC00894,miR-495-3p and Rab23 in tissues and in vitro cultured cells Huh7,SMMC-7721,HepG2 and L-02.Cells Huh7 were randomly separated into Huh7 group,NC group,si-LINC00894 group,anti-NC group,and anti-miR-495-3p group.CCK-8,flow cytometry and Transwell were used to compare the cell proliferation,apoptosis,migration and invasion of each group.Western blot was used to detect the expression of Rab23 and proliferation-related proteins in cells.The relationship between LINC00894 and miR-495-3p,miR-495-3p and Rab23 was analyzed and verified by dual luciferase reporter gene assay.Results The mRNA and protein expression of LINC00894 and Rab23 were higher in cancer tissues and cells of liver cancer patients,while the mRNA expression of miR-495-3p was lower(P＜0.05).The apoptosis rate of si-LINC00894 group was higher than that of Huh7 group and NC group,and the absorbance at 24 h,48 h,and 72 h,numbers of migrating and invading cells,and expression of Rab23 in cells were lower than those in Huh7 group and NC group(P＜0.05);the absorbance at 24 h,48 h,and 72 h,numbers of migrating and invading cells,and expression of Rab23 in cells in the anti-miR-495-3p group were higher than those in the anti-NC group and si-LINC00894 group,the apoptosis rate of cells was lower than that in the anti NC group and si-LINC00894 group(P＜0.05).The luciferase activity in the WT-LINC00894+miR-495-3p group was lower than that in the WT-LINC00894+miR-NC group(P＜0.05),the luciferase activity in the WT-Rab23+miR-495-3p group was lower than that in the WT-Rab23+miR-NC group(P＜0.05).Conclusion Downregulation of LINC00894 can promote the expression of miR-495-3p,inhibit the expression of Rab23,and thus exert the inhibitory effect on the malignant biological behavior of liver cancer cells.

BACKGROUND:Acute lung injury is a common severe complication in sepsis patients,with a complex pathogenesis,for which there is currently no effective pharmacological treatment.The therapeutic mechanism by which human umbilical cord-derived mesenchymal stem cells improve sepsis-induced acute lung injury through the inhibition of excessive cellular pyroptosis is increasingly receiving attention.OBJECTIVE:To investigate the effects and mechanisms of human umbilical cord-derived mesenchymal stem cells on cellular pyroptosis in lung tissues of mice with sepsis-induced acute lung injury.METHODS:Totally 48 male Balb/c mice were randomly divided into sham,model,and treatment groups(n=16 per group).The model and treatment groups underwent cecum ligation and puncture to establish a sepsis-induced acute lung injury model,while the sham group underwent laparotomy without further procedures.The treatment group received a tail vein injection of 200 μL of human umbilical cord-derived mesenchymal stem cell suspension(5x105 cells)6 hours after the procedure,while the model and sham groups received 200 μL of saline 6 hours after the surgery.Twenty-eight hours post-procedure,five mice from each group were randomly selected for tail vein injection of Evans blue dye to assess pulmonary vascular permeability.The remaining mice from each group had their bronchoalveolar lavage fluid and lung tissues collected for ELISA to measure levels of interleukin-1β and interleukin-18,cell counts,and macrophage numbers in the bronchoalveolar lavage fluid.Hematoxylin and eosin staining was used to observe the pathological morphology of lung tissue.TUNEL staining was used to assess cellular pyroptosis.RT-PCR and western blot analyses were conducted to measure mRNA and protein expression levels of Toll-like receptor 4,GSDMD,and Caspase-11 in lung tissues.RESULTS AND CONCLUSION:Compared to the model group,the treatment group showed a significant decrease in pulmonary vascular permeability at 28 hours post-procedure(P＜0.05),reduced levels of interleukin-1β and interleukin-18 in bronchoalveolar lavage fluid(P＜0.05),and lower cell and macrophage counts(P＜0.05).Lung injury severity was reduced,with a decreased pyroptosis index(P＜0.05)and significantly lower levels of Toll-like receptor 4,GSDMD,GSDMD-N,and Caspase-11 mRNA and protein expression in lung tissues(P＜0.05).These results suggest that human umbilical cord-derived mesenchymal stem cells may improve the severity of sepsis-induced lung injury to some extent by inhibiting the activation of the Toll-like receptor 4/Caspase-11/GSDMD signaling pathway and reducing cellular pyroptosis in lung tissues.

Objective To evaluate the efficacy and safety of enteric-coated metformin hydrochloride capsules(Junlida?)in patients with T2DM and poor glycemic control under lifestyle interventions.Methods In this study,419 patients with T2DM were recruited from 15 research centers from July 2020 to March 2022,and randomly divided into observation(Obs)group(n=209)and control group(Con,n=210)using a multicenter,randomized,double-blind,non-inferiority trial design.Patients in the Obs group were treated with enteric-coated Metformin hydrochloride capsules(Junlida?),and patients in the Con group were treated with Metformin hydrochloride tablets(Glucophage?).The optimal effective dose of 2 g/d was achieved within 4 weeks,and the reasonable dose was maintained until the end of treatment.The treatment period was 24 weeks.HbA1c and its compliance rate,FPG,and body weight were compared between the two groups in full analysis set(FAS)and protocol set(PPS).Safety and adverse events(AE)were evaluated in safety set(SS).Results A total of 414 participants were randomized(207 cases in Obs group and 207 cases in Con group).414 cases in FAS population(207 cases in Obs group and 207 cases in Con group),and 328 cases in PPS population(164 cases in Obs group and 164 cases in Con group),and 414 cases in SS population(207 cases in Obs group and 207 cases in Con group).After treatment,HbA1c,FPG and body weight were lower in both groups(P<0.05)in FAS and PPS.HbA1c compliance rate was not significantly different between the two groups in FAS and PPS(P>0.05).The results of non-inferiority test showed that the lower limit was>-0.4%in both FAS(-0.154,95%CI-0.384～0.069)and PPS(-0.139,95%CI-0.390～0.112),and the Obs group reached non-inferiority end point.The achievement rate,compliance rate,safety index and incidence of AE were not significantly different between the two groups(P>0.05).Conclusions Junlida? demonstrated non-inferiority to Glucophage? in glycemic control and can be safely and effectively used in patients with diabetes.

Functional dyspepsia (FD), characterized by persistent or recurrent dyspeptic symptoms without identifiable organic, systemic or metabolic causes, is an increasingly recognized global health issue. The objective of this guideline is to equip clinicians and nursing professionals with evidence-based strategies for the management and treatment of adult patients with FD using traditional Chinese medicine (TCM). The Guideline Development Group consulted existing TCM consensus documents on FD and convened a panel of 35 clinicians to generate initial clinical queries. To address these queries, a systematic literature search was conducted across PubMed, EMBASE, the Cochrane Library, China National Knowledge Infrastructure (CNKI), VIP Database, China Biology Medicine (SinoMed) Database, Wanfang Database, Traditional Medicine Research Data Expanded (TMRDE), and the Traditional Chinese Medical Literature Analysis and Retrieval System (TCMLARS). The evidence from the literature was critically appraised using the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) approach. The strength of the recommendations was ascertained through a consensus-building process involving TCM and allopathic medicine experts, methodologists, pharmacologists, nursing specialists, and health economists, leveraging their collective expertise and empirical knowledge. The guideline comprises a total of 43 evidence-informed recommendations that span a range of clinical aspects, including the pathogenesis according to TCM, diagnostic approaches, therapeutic interventions, efficacy assessments, and prognostic considerations.

OBJECTIVE: This study aimed to explore the association between body mass index (BMI) and mortality based on the 10-year population-based multicenter prospective study. METHODS: A general population-based multicenter prospective study was conducted at four sites in rural China between 2013 and 2023. Multivariate Cox proportional hazards models and restricted cubic spline analyses were used to assess the association between BMI and mortality. Stratified analyses were performed based on the individual characteristics of the participants. RESULTS: Overall, 19,107 participants with a sum of 163,095 person-years were included and 1,910 participants died. The underweight (< 18.5 kg/m ²) presented an increase in all-cause mortality (adjusted hazards ratio [ aHR] = 2.00, 95% confidence interval [ CI]: 1.66-2.41), while overweight (≥ 24.0 to < 28.0 kg/m ²) and obesity (≥ 28.0 kg/m ²) presented a decrease with an aHR of 0.61 (95% CI: 0.52-0.73) and 0.51 (95% CI: 0.37-0.70), respectively. Overweight ( aHR = 0.76, 95% CI: 0.67-0.86) and mild obesity ( aHR = 0.72, 95% CI: 0.59-0.87) had a positive impact on mortality in people older than 60 years. All-cause mortality decreased rapidly until reaching a BMI of 25.7 kg/m ² ( aHR = 0.95, 95% CI: 0.92-0.98) and increased slightly above that value, indicating a U-shaped association. The beneficial impact of being overweight on mortality was robust in most subgroups and sensitivity analyses. CONCLUSION This study provides additional evidence that overweight and mild obesity may be inversely related to the risk of death in individuals older than 60 years. Therefore, it is essential to consider age differences when formulating health and weight management strategies.
