ObjectiveThis study aims to explore the potential mechanism of the Xiezhuo Jiedu formula in regulating pyroptosis for the treatment of ulcerative colitis （UC） using bioinformatics and in vivo animal experiments. MethodsDifferentially expressed genes （DEGs） in colon tissues of UC patients were retrieved from the Gene Expression Omnibus （GEO） database. Pyroptosis-related genes were obtained from the GEO and GeneCards databases. The intersection of these datasets yielded pyroptosis-related DEGs （Pyro-DEGs）. Pyro-DEGs were subjected to Gene Ontology （GO） and Kyoto Encyclopedia of Genes and Genomes （KEGG） enrichment analysis using the Metascape database. A protein-protein interaction （PPI） network was constructed using the STRING database. Least absolute shrinkage and selection operator （LASSO） prediction model and receiver operating characteristic （ROC） analysis were conducted to identify core Pyro-DEGs with diagnostic and therapeutic potential. Immune infiltration analysis of the UC datasets was performed using the deconvolution method （CIBERSORT）， along with correlation analysis with core Pyro-DEGs. Sixty male Sprague-Dawley （SD） rats were randomly divided into a control group， a model group， high-， medium-， and low-dose groups of Xiezhuo Jiedu formula （26.64， 13.32， 6.66 g·kg^-1）， and a mesalazine group （0.27 g·kg^-1）， with 10 rats in each group. UC was established by intrarectal administration of 3，5-trinitrobenzenesulfonic acid （TNBS） dissolved in ethanol. The control and model groups were given distilled water by gavage， while the treatment groups were administered the corresponding drugs for 7 consecutive days. Hematoxylin-eosin （HE） staining was used to observe the colon histopathology. Enzyme-linked immunosorbent assay （ELISA） was used to detect the levels of inflammatory factors such as interleukin-1β （IL-1β）， IL-10， IL-18， and transforming growth factor-β （TGF-β）. Immunohistochemistry （IHC） and Western blot were applied to detect the expression of Caspase-1， gap junction alpha-1 protein （GJA1）， peroxisome proliferator-activated receptor gamma （PPARG）， and S100 calcium-binding protein A8 （S100A8）. Real-time quantitative polymerase chain reaction （Real-time PCR） was utilized to measure mRNA expression of Caspase-1， GJA1， PPARG， and S100A8. Western blot was performed to assess protein expression levels of Caspase-1， GJA1， PPARG， and S100A8. ResultsGEO datasets GSE87466 and GSE87473 yielded 64 Pyro-DEGs. KEGG analysis indicated that these genes were enriched in the NOD-like receptor signaling pathway， tumor necrosis factor （TNF） signaling pathway， and hypoxia-inducible factor 1 （HIF-1） signaling pathway. Four core Pyro-DEGs （Caspase-1， GJA1， PPARG， and S100A8） were identified. Immune infiltration analysis showed that expression of these genes was positively correlated with mast cells， neutrophils， M0 macrophages， M1 macrophages， and dendritic cells. Animal experimental results indicated that compared with the control group， the model group had significantly increased levels of IL-1β and IL-18， significantly decreased levels of IL-10 and TGF-β. The model group showed enhanced Caspase-1， GJA1， and S100A8 staining， and significantly increased mRNA and protein expression of Caspase-1， GJA1， and S100A8 （P<0.01）. In contrast， the expression of PPARG was reduced in the model group （P<0.01）. After treatment， all dosage groups showed varying degrees of improvement （P<0.05， P<0.01）， with the high-dose group showing the most significant improvement （P<0.01）. ConclusionCaspase-1， GJA1， PPARG， and S100A8 are core Pyro-DEGs closely associated with the pathogenesis of UC. These genes may collaborate with immune cells such as mast cells， neutrophils， and M0 macrophages to mediate disease development. The Xiezhuo Jiedu formula may regulate the expression of core Pyro-DEGs through the NOD-like receptor， TNF， and HIF-1 core signaling pathways， thereby modulating immune homeostasis in UC rats and effectively alleviating UC.

Objective To investigate the effect of butorphanol combined with parecoxib sodium on patient-controlled intravenous analgesia(PCIA)after uvulo-palato-pharyngo-plasty(UPPP).Methods Eighty patients who were admitted to our hospital from October 2021 to May 2023 and planned to receive UPPP were collected,and they were randomly assigned to the paroxicib sodium group(D group),the butorphanol low-dose group(B1 group),the butorphanol medium dose group(B2 group),and the butorphanol high-dose group(B3 group),with 20 cases in each group.Patients in the D group received 40 mg of paroxycoxib sodium with 0.9% sodium chloride injection for analgesia,and patients in the B1 group,the B2 group,and the B3 group were combined with 3.0 μg·kg-1·h-1,4.0 μg·kg-1·h-1,and 5.0 μg·kg-1·h-1 of butorphanol respectively on the basis of D group.The heart rate and mean arterial pressure before PCIA and 2 hours,12 hours,24 hours,and 48 hours after PCIA were compared among the four groups;the pain visual analogue scale(VAS)score,Ramsay score 2 hours,12 hours,24 hours,and 48 hours after PCIA were compared among the four groups;the number of PCIA compression,and incidence of adverse reactions were recorded.Results There was no statistically significant difference in the heart rate or mean arterial pressure before PCIA and 2 hours,12 hours,24 hours,and 48 hours after PCIA among the four groups(P>0.05).Compared with the D group,the VAS scores 2 hours,12 hours,24 hours,and 48 hours after PCIA of the B1,B2,and B3 groups significantly decreased(P<0.05),and the higher the dose of butorphanol,the lower the VAS score(P<0.05).Compared with the D group,the Ramsay scores 2 hours,12 hours,24 hours,and 48 hours after PCIA of the B1,B2,and B3 groups obviously increased(P<0.05),and the higher the dose of butorphanol,the higher the Ramsay score(P<0.05).The total incidence of adverse reactions in the B3 group was obviously higher than that in the D group,the B1 group,and the B2 group(P<0.05).Compared with the D group,patients in the B1,B2,and B3 groups had significantly fewer PCIA compressions(P<0.05),and the higher the dose of butorphanol,the fewer the PCIA compressions(P<0.05).Conclusion The effect of butorphanol combined with parecoxib sodium in PCIA after UPPP is better,and combined with 4.0 μg·kg-1·h-1 parecoxib sodium has more significant analgesic effect and higher safety.

The targeted content analysis method was used to analyze data.Results:Four themes were extracted, namely triggering factors of fear of recurrence, perception of atrial fibrillation recurrence, negative emotional distress, and insufficient ability to cope with atrial fibrillation recurrence.Conclusions:For patients with atrial fibrillation during the "blanking period" after catheter ablation, medical and nursing staff should closely monitor the patient's cognitive level and psychological state, and carry out targeted health education to meet the patient's needs for postoperative disease management, life adaptation, and other aspects, so as to reduce the fear of recurrence in atrial fibrillation patients during the "blanking period" after surgery.

Objective To explore the risk factors for suicidal ideation among the relatives and friends of suicide victims through psychological support hotline.Methods Calls from the relatives and friends of suicide victims to the Beijing psychological support hotline between 2009 and 2023 were included.Their current suicidal ideation was assessed by asking whether they had suicidal thoughts in the past two weeks.Demographic information of the callers was collected and the severity of their depression was assessed using the depression diagnostic screening scale.Interviews were conducted to evaluate distress,sense of hope,history of suicide attempts,and suicide risk factors.Logistic regression analysis was used to explore the risk factors for suicidal ideation among callers.Results A total of 360 cases were included in this study.There were 50.3%(181 cases)of the callers reporting suicidal ideation within 2 weeks before the call.Years of education(OR=0.86,95%CI:0.79-0.94)and high levels of hope(OR=0.19,95%CI:0.11-0.32)were protective factors against suicidal ideation in callers.History of suicide attempts(OR=2.01,95%CI:1.20-3.36),high levels of distress(OR=3.28,95%CI:1.92-5.61),and high levels of depression(OR=1.73,95%CI:1.05-2.84)were independent risk factors for suicidal ideation in callers.Conclusions History of suicide attempts,high levels of distress and high levels of depression among the relatives and friends of suicide victims calling the psychological support hotline are risk factors for their own suicidal ideation.

Objective To investigate risk factors of medication non-adherence in elderly patients with hypertension through Meta-analysis.Methods Literatures on medication non-adherence in elderly patients with hypertension were systematically reviewed across various databases,from inception to September 1st 2023,including CNKI,VIP,Wangfong Database,SinoMed,PubMed,Web of Science,Cochrane Library、EMbase.Meta-analysis was conducted using RevMan 5.4.Results A total of 19 articles were included,comprising a total of 18 220 patients in sample size.Meta analysis identified 10 risk factors,showed significant association(P<0.05)with:age[OR=1.36,95%CI=(1.00,1.86)],place of residence[OR=1.91,95%CI=(1.33,2.75)],method of payment for medical expenses[OR=1.60,95%CI=(1.38,1.86)],income level[OR=1.68,95%CI=(1.45,1.95)],occupational status[OR=1.79,95%CI=(1.37,2.36)],social support[OR=1.43,95%CI=(1.27,1.60)],comorbidity[CI=0.33,95%(0.19,0.58)],frequency of blood pressure measurement[CI=1.53,95%(1.14,2.05)],disease awareness[OR=1.70,95%CI=(1.44,2.00)]and dedication frequency[OR=1.44,95%CI=(1.16,1.79)].In addition,the number of influencing factors such as gender,marital status,depression,cognitive impairment,and complications was included in<3 articles,and only descriptive analysis was conducted.Conclusion Healthcare providers should focus on the identification and management of the risk factors associated with medication non-adherence in elderly patients with hypertension,therefore to reduce the incidence of medication non-adherence.

Objective To investigate the prevalence of Helicobacter pylori(H.pylori)positivity in the urban areas of Chongqing and its relationship with age,season,and gender.Methods A total of 4,836 patients who underwent 14C-UBT testing at our hospital from April 2023 to March 2024 were selected.The detection rate of H.pylori and the infection status of H.pylori in different age groups,genders,and seasons were analyzed.Logistic regression analysis was performed on factors related to H.pylori infection identified in the univariate analysis.Results The positive detection rate of H.pylori in the 4,836 subjects was 29.3％,with a higher rate in males than in females,showing a statistically significant difference(P＜0.05).The highest positive detection rate of H.pylori was in the summer season,and the peak positivity rate for H.pylori was observed in the 30-39 age group.There was a statistically significant difference in the positive detection rate of H.pylori across seasons and among different age groups(P＜0.05).Multivariate logistic regression analysis indicated that gender,age,and season were all influential factors in the outcome of H.pylori infection(P＜0.05).Conclusion The prevalence of H.pylori infection in the urban areas of Chongqing is relatively low,and gender,age,and season are all influential factors for H.pylori infection.

Objective To explore the correction of beam trajectories in the presence of fringe fields in magnetic resonance imaging-guided proton therapy and dose changes in the body before and after correction.Methods The open-source treatment planning software matRad was used to design plans for brain tumor,liver tumor,and prostate cancer cases,and simulation studies were conducted in the Monte Carlo simulation toolkit TOPAS to calculate proton dose distribution.A proton beam trajectory correction model suitable for three-dimensional magnetic fields was established,and a beam trajectory correction algorithm was developed.The deflection of the proton Bragg peak in the presence of fringe fields was analyzed.Furthermore,3 treatment plans were simulated and dose correction was carried out when the fringe field existed.Gamma analysis method is used to evaluate the correction effect;and the dose changes in the target area and organs-at-risk after correction were quantitatively analyzed.Results The perturbation of the magnetic field would cause lateral deflection of the proton beam trajectory,and the presence of fringe fields would significantly increase this effect,which increased with the increasing of beam energy.When the fringe field existed,the treatment plans for brain tumor,liver tumor,and prostate cancer were corrected.Under the 3%/3 mm criterion,the gamma passing rates for target area were 94.844%,92.054%,and 97.863%,respectively,and after correction,the total dose in the body was increased by 2.8%,2.5%,and 1.5%,respectively.The increased dose was mainly contributed by incident protons.Conclusion In magnetic resonance imaging-guided proton therapy,the effects of fringe fields should be considered.The increase in incident proton beam energy after correction will lead to an increase in the total dose in the body.Since the beam trajectory still has curvature,the dose changes differently in different organs-at-risk.
