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 efficacy of radiotherapy in patients with advanced esophageal cancer receiving first-line chemoimmunotherapy.Methods:A retrospective analysis was conducted on the data of 137 patients with Stage Ⅳ esophageal squamous cell carcinoma (ESCC) treated at our hospital from January 2018 to May 2023. These patients were divided into two groups: a group treated with first-line chemoimmunotherapy combined with radiotherapy (chemoimmunotherapy + radiotherapy group, n = 43) and a group treated with only chemoimmunotherapy ( n = 94). Inverse probability of treatment weighting (IPTW) was applied to balance baseline characteristics between the groups. With overall survival (OS) and progression-free survival (PFS) as study endpoints, the survival data were analyzed using the Kaplan-Meier method, the log-rank test, and the Cox regression method. Results:Before calibration, the chemoimmunotherapy + radiotherapy group significantly outperformed the sole chemoimmunotherapy group in median PFS (13.6 months vs. 7.0 months; HR: 0.501, 95% CI: 0.309-0.811, P = 0.005). After calibration using the COX proportional-hazards model for age, gender, Eastern Cooperative Oncology Group (ECOG) performance status, smoking history, T/N/M stage, and tumor location, the chemoimmunotherapy + radiotherapy group still had significant advantages in PFS (14.7 months vs. 7.0 months; HR: 0.441, 95% CI: 0.261-0.745, P = 0.002). IPTW analysis further confirmed this trend (13.9 months vs. 7.0 months; HR: 0.492, 95% CI: 0.304-0.795, P < 0.001). Specifically, the median OS of the chemoimmunotherapy + radiotherapy group demonstrated significant improvement in all analyses: pre-calibration (29.5 months vs. 18.0 months; HR: 0.507, 95% CI: 0.297-0.867, P = 0.013), after calibration using the Cox model (27.5 months vs. 16.7 months; HR: 0.470, 95% CI: 0.266-0.830, P = 0.009), and after calibration using IPTW (29.5 months vs. 16.9 months; HR: 0.448, 95% CI: 0.262-0.764, P < 0.001). Conclusions:The combination of radiotherapy and first-line chemoimmunotherapy can significantly improve survival outcomes of patients with advanced ESCC, suggesting its potential as a standard treatment strategy.

The prevalence of chronic constipation among the elderly is significant, exerting adverse effects on both their physical and mental health.Presently, pharmacological therapy remains the predominant treatment modality for elderly patients with chronic constipation; however, prolonged use can lead to drug dependence, tolerance, and adverse effects.This article systematically reviews non-pharmacological interventions for chronic constipation in elderly patients, both domestically and internationally, aiming to provide a comprehensive reference for clinical practice.

eIF3a is a N ⁶-methyladenosine (m⁶A) reader that regulates mRNA translation by recognizing m⁶A modifications of these mRNAs. It has been suggested that eIF3a may play an important role in regulating translation initiation via m⁶A during infection when canonical cap-dependent initiation is inhibited. However, the death of animal model studies impedes our understanding of the functional significance of eIF3a in immunity and regulation in vivo. In this study, we investigated the in vivo function of eIF3a using eIF3a knockout and knockdown mouse models and found that eIF3a deficiency resulted in splenic tissue structural disruption and multi-organ damage, which contributed to severe sepsis induced by Lipopolysaccharide (LPS). Ectopic eIF3a overexpression in the eIF3a knockdown mice rescued mice from LPS-induced severe sepsis. We further showed that eIF3a maintains a functional and healthy immune system by regulating B cell function and quantity through m⁶A modification of mRNAs. These findings unveil a novel mechanism underlying sepsis, implicating the pivotal role of B cells in this complex disease process regulated by eIF3a. Furthermore, eIF3a may be used to develop a potential strategy for treating sepsis.

ObjectiveTo investigate the protective effect and mechanism of action of flavonoid combination of Alpiniae Officinarum Rhizoma （A. officinarum） against Helicobacter pylori （H. pylori） gastritis in mice. MethodsAfter acclimatization for one week， 56 SPF-grade healthy C57BL/6J mice were gavaged with mixed antibiotics for three consecutive days. They were randomly divided into a normal group， model group， positive drug group （triple therapy group）， and low- and high-dose groups （100， 200 mg·kg^-1） of flavonoid combination of A. officinarum. The H. pylori gastritis mice model was established by gavage with H. pylori bacterial suspension in each group except for the normal group. After successful modeling， mice were administrated with corresponding drugs once a day for two weeks. Hematoxylin-eosin （HE） staining was used to observe the pathological changes in gastric tissue. Rapid urease test paper was used to detect the positive rate of H. pylori. Silver staining was used to observe the H. pylori adherence on the surface of gastric tissue. Immunohistochemistry was used to detect the protein expression of interleukin-8 （IL）-8 and myeloid differentiation factor （MyD88） in gastric tissue. The serum levels of IL-6， tumor necrosis factor-α （TNF-α）， IL-8， and IL-1β were detected by enzyme-linked immunosorbent assay （ELISA）. The expressions of phosphatidylinositol 3-kinase/protein kinase B （PI3K/Akt） protein were detected by Western blot. ResultsCompared with those in the normal group， mice in the model group had lower gastric weight coefficients， higher pH of gastric juice， 100% H. pylori infection rate， and significantly changed gastric histopathology. The expressions of IL-8 and MyD88 proteins in the gastric tissue of mice in the model group were significantly elevated， and the serum levels of inflammatory factors IL-6， TNF-α， IL-8， and IL-1β were significantly up-regulated in mice. Compared with that in the model group， the gastric weight coefficient of mice in each treatment group of the flavonoid combinations of A. officinarum was elevated （P<0.01）， and the pH of gastric juice was reduced （P<0.01）. The infection rate of H. pylori was reduced. The expressions of IL-8 and MyD88 proteins in the gastric tissue of mice in the treatment groups were significantly reduced （P<0.01）， and the serum levels of inflammatory factors IL-6， TNF-α， IL-8， and IL-1β were significantly reduced in a dose-dependent manner （P<0.01）. The flavonoid combinations of A. officinarum down-regulated the expression of PI3K and Akt proteins in H. pylori gastritis-infected cells （P<0.01）. ConclusionThe protective effect of flavonoid combinations of A. officinarum against H. pylori gastritis is associated with the inhibition of H. pylori infection rate and regulation of PI3K/Akt signaling pathway， resulting in inhibiting the release of inflammatory factors.

Objective Exploring the therapeutic mechanism of Yishen Jiangzhuo Granules(YSJZG)on chronic kidney disease(CKD)based on mitochondrial dynamics and apoptosis of renal tubular epithelial cells.Methods The CKD model of rats with 5/6 nephrectomy was adopted and divided into 6 groups according to random number table:sham operation control group,model group,emodin group(500 mg/kg/d),Yishen Jiangzhuo granule low,middle and high dose groups.After 8 weeks of treatment with YSJZG,serum creatinine(SCR)and urea nitrogen(BUN),pathological changes of renal cortex,mitochondrial morphology and ultrastructure were detected,and mitochondrial kinetic protein in renal tubular epithelial cells was detected by immunohistochemistry(Drp1,Fis1)and fusion proteins(Opa1,Mfn1)were detected by Western blot,and apoptotic proteins(CytC,Bax)in cytoplasm and mitochondria were detected by real-time PCR.Results Renal injury:Compared with the model group,YSJZG groups significantly reduced the levels of SCR and BUN,renal tubular degeneration and necrosis,and mitochondrial structural damage in rats.Renal tubule mitochondrial dynamic protein:Compared with the model group,the expression of division proteins Drp1 and Fis1 was downregulated,the expression of fusion proteins Opa1 and Mfn1 was upregulated,and transmission electron microscopy observed that the mitochondrial fragmentation changes were relatively mild.Apoptosis related indicators and mtDNA copy number of renal tubular cells:Compared with the model group,the content of Bax protein in renal tubular epithelial cells of YSJZG groups increased significantly in cytoplasm(P<0.05)and decreased significantly in mitochondria(P<0.05).The content of CytC protein decreased significantly in cytoplasm(P<0.05)and increased significantly in mitochondria(P<0.05).The copy number of mtDNA increased significantly(P<0.05),and the total levels of SMAC,CytC and Bax mRNA decreased significantly(P<0.05).Correlation between mitochondrial dynamic protein and apoptosis in renal tubular cells:Pearson correlation analysis showed that the expression of Drp1 and Fis1 was negatively correlated with the expression of CytC in mitochondria,and positively correlated with the expression of CytC in cytoplasm.The expression levels of fusion proteins Opa1 and Mfn1 showed a significant positive correlation with CytC expression in mitochondria,and a significant negative correlation with CytC expression in cytoplasm.Conclusion YSJZG can significantly delay the progression of CKD,and its mechanism may be achieved by regulating mitochondrial dynamics of renal tubular epithelial cells,thereby inhibiting endogenous cell apoptosis pathway.

Objective:To investigate the changing trend of mortality rate and death cause spectrum among household-registered residents aged 60 and above in Beijing from 2007 to 2020.Methods:The mortality data was collected from the Beijing Death Information Registration and Management System. We calculated the mortality rates and constituent ratios by gender, age groups, and death causes and estimated the changing trend of mortality rate and average annual percent change (AAPC) by Joinpoint 4.3.1.Results:The crude mortality rate decreased from 27.62‰ in 2007 to 23.55‰ in 2020 (AAPC=-1.18%, P<0.001), and the standard rate also decreased from 25.39‰ in 2007 to 19.85‰ in 2020 (AAPC=-1.68%, P<0.001) among registered residents aged 60 and above in Beijing. The top 5 causes of death were heart diseases, malignant tumors, cerebrovascular diseases, respiratory diseases, and endocrine and nutritional metabolic diseases, accounting for 87.1% of the total deaths. The mortality rates of heart diseases (AAPC=-1.08%, P=0.024), cerebrovascular diseases (AAPC=-3.79%, P<0.001), malignant tumors (AAPC=-0.31%, P=0.006) and respiratory diseases (AAPC=-5.56%, P=0.007) showed a decreasing trend. The rate of injury and poisoning showed an increasing trend (AAPC=1.54%, P=0.001), while no statistically significant change was found in endocrine and nutritional metabolic diseases mortality rates (AAPC=-1.46%, P=0.054). Conclusions:The mortality rate of registered residents aged 60 years and over in Beijing showed a downward trend from 2007 to 2020. Heart diseases, cerebrovascular diseases, malignant tumors, and respiratory diseases should be treated as the key diseases for prevention and control, and targeted measures should be taken to improve the health level of the elderly population.
