Objective:To explore the correlation among disease uncertainty,quality of life and psychological resilience in patients undergoing radical gastrectomy for gastric cancer.Methods:This study was a prospective study.A total of 106 patients who underwent radical gastrectomy for gastric cancer and were admitted to Shanxi Integrated Traditional Chinese and Western Medicine Hospital from July 2023 to July 2024 were included in observation group.Connor-davidson resilience scale(CD-RISC),Mishel disease uncertainty scale(MUIS)and European qrganization for research and treatment of cancer quality of life questionnaire-C30(EORCT QLQ-C30)were used to evaluate the psychological resilience,disease uncertainty and quality of life of observation group.Pearson test was used to analyze the correlations among disease uncertainty,quality of life and psychological resilience in patients undergoing radical gastrectomy for gastric cancer.Univariate and multivariate logistic regression analyses were used to investigate the influencing factors of decreased postoperative psychological resilience in patients undergoing radical gastrectomy for gastric cancer.Result:Pearson test analysis showed that,the MUIS score and EORCT QLQ-C30 score of patients undergoing radical gastrectomy for gastric cancer was negatively correlated with CD-RISC(P＜0.05).Through univariate analysis,age,educational level,annual family income,MUIS and EORCT QLQ-C30 were the influencing factors of decreased psychological resilience in patients undergoing radical gastrectomy for gastric cancer(P＜0.05).Multivariate logistic analysis showed that,increased age,educational level of primary school or below,annual family income＜50,000 yuan,increased MUIS score and increased EORCT QLQ-C30 score were independent risk factors for decreased psychological resilience in patients undergoing radical gastrectomy for gastric cancer.Conclusion:The disease uncertainty,quality of life and psychological resilience of patients undergoing radical gastrectomy for gastric cancer are negatively correlated.Increased age,educational level of primary school or below,annual family income＜50,000 yuan,increased MUIS score and increased EORCT QLQ-C30 score are independent risk factors for decreased psychological resilience in patients undergoing radical gastrectomy for gastric cancer.

Objective Cigarette smoke(CS)exposure combined with Klebsiella pneumoniae(KP)infection in mice was used to establish a model of chronic obstructive pulmonary disease(COPD)to investigate the mechanism of airway remodeling.Methods Male BALB/c mice were randomly divided into a Control group,CS group,KP group,and CS+KP group.The mice were exposed to CS,KP,and CS+KP from weeks 1 to 8,and were sacrificed in weeks 4,8,16,and 24.MV,Penh,MLI,MAN,and changes in lung pathological structure were detected.The expression levels of IL-1β and TNF-α in lung tissue were detected by ELISA.Collagen deposition was observed by Masson staining and immunohistochemistry.α-SMA and TGF-β1 expression in lung tissue was detected by immunofluorescence.Human bronchial epithelioid cells(16HBE)were also stimulated by CS and lipopolysaccharide(LPS)in vitro,and the expression levels of airway epithelial junction proteins,autophagy-related protein,and mTOR signaling proteins were detected.Results Compared with the Control group,the CS+KP group mice had significantly decreased MV from weeks 4 to 24(P＜0.05 or P＜0.01)and significantly increased Penh from weeks 8 to 24(P＜0.05 or P＜0.01);while the CS group had markedly decreased MV and markedly increased Penh from weeks 8 to 16(P＜0.05 or P＜0.01).Compared with the Control group,massive inflammatory cell infiltration,alveolar wall thickening,alveolar rupture and fusion,and airway wall thickening were observed by HE staining in CS+KP group from weeks 4 to 24.The CS+KP group mice had significantly decreased MAN and significantly increased MLI,IL-1β and TNF-α in their lung tissue from weeks 4 to 24(P＜0.05 or P＜0.01).The aforementioned inflammation and tissue damage were observed in the CS group and the KP group from week 8 to 16.Compared with the Control group,COL Ⅰ,COL Ⅲ,α-SMA,and TGF-β1 were significantly increased in lung tissue of mice in the CS+KP group from weeks 8 to 16(P＜0.01);COL Ⅰ was significantly increased in the CS group and KP group from weeks 8 to 16(P＜0.01).In addition,increased E-cad and decreased N-cad(P＜0.05);significantly decreased LC3B and Beclin-1(P＜0.05);and significantly increased p-mTORC1,p-P70-S6K,and p-4E-BP1 expression were observed in 16HBE cells exposed to CS and LPS(P＜0.05 or P＜0.01).Conclusion Pulmonary functional decline,pathological changes in lung tissue,and airway remodeling appeared to occur early and persist in COPD mice induced by CS and KP.The mechanisms may be related to the activation of mTORC1 signaling pathway and subsequent inhibition of autophagy.

Objective:To investigate the correlation between postoperative perceived stress,quality of life and fear of cancer recurrence(FCR)in elderly non-small-cell lung cancer(NSCLC)patients.Methods:This study was a prospective research design,a total of 147 elderly NSCLC patients who visited Shanxi Integrated Traditional Chinese and Western Medicine Hospital from January 2023 to June 2024 were prospectively selected for the study.All patients underwent thoracoscopic lobectomy.FCR in patients was evaluated by fear of disease progression simplified scale(FoP-Q-SF),and they were divided into dysregulation group and non dysregulation group according to the FoP-Q-SF score.Quality of life was evaluated by functional assessment of cancer therapy-lung cancer(FACT-L).Perceived stress was evaluated by Chinese version of the perceived stress scale(CPSS)score.The scores of postoperative perceived stress,quality of life and postoperative FCR in elderly NSCLC patients were analyzed,and the influence of demographic and clinical characteristics on the postoperative FCR in elderly NSCLC patients.The postoperative perceived stress and quality of life scores of elderly NSCLC patients with different FCR were compared,the correlation between postoperative FCR and perceived stress and quality of life in elderly NSCLC patients were analyzed,as well as the model fitting index of the influence of postoperative perceived stress and quality of life on FCR in elderly NSCLC patients.Results:The postoperative CPSS score in elderly NSCLC patients was(52.17±4.02)points,the FACT-L score was(80.39±4.56)points,and the total score of FoP-Q-SF was(31.16±8.69)points.Family relationship,economic burden of disease,chemotherapy and clinical stage were closely associated with the postoperative FCR in elderly NSCLC patients(P＜0.05).The CPSS score in dysregulation group was higher than that in nondysregulation group,and the FACT-L score was lower than that in nondysregulation group(P＜0.05).Pearson correlation analysis,postoperative FCR in elderly NSCLC patients was positively correlated with perceived stress,but negatively correlated with quality of life(P＜0.05).The postoperative quality of life in elderly NSCLC patients was recorded as the independent variable,the postoperative perceived stress was recorded as the mediating variable,and the postoperative FCR was recorded as the dependent variable,a structural model of the mediating effect was routinely constructed.The results showed that the model fits well.Quality of life had a direct negative predictive effect on postoperative FCR in elderly NSCLC patients(P＜0.05),and could affect FCR through postoperative perceived pressure(P＜0.05),with the mediating effect accounting for 34.15％of the total effect.After repeatedly sampling the data using the Bootstrap method and implementing the mediating effect,the 95％CI of each model path did not include 0,indicating that the difference in the mediating effect was statistically significant(P＜0.05).Conclusion:Postoperative FCR in elderly NSCLC patients is positively correlated with perceived stress,but negatively correlated with quality of life,clinically,monitoring such indicators can be considered to better evaluate the postoperative FCR in elderly NSCLC patients.

Aim To explore the mechanism by which the compound Chaijin Jieyu formula(CCJJY)regulates the TLR4/NLRP3 signaling pathway to inhibit central oxidative stress and improve hippocampal synaptic plasticity damage in depression.Methods SD rats were randomly divided into the control group,chronic unpredictable mild stress group,sleep deprivation group,chronic unpredictable mild stress combined with sleep deprivation group,positive drug group(venlafax-ine+melatonin),low-dose group of CCJJY,medium dose group of CCJJY,and high-dose group of CCJJY,with nine rats in each group.Except for the control group,a rat model of depression complicated with in-somnia was established using chronic unpredictable mild stress combined with sleep deprivation.Depres-sion-like and sleep behaviors in rats were evaluated through weight,food intake,water maze,and pento-barbital sodium tests.ELisa was used to detect ROS,AANAT,and HPLC-EC was used to detect 5-HT con-tent,while Western blot/RT-PCR was used to detect the expression of IL-1β,TLR4,NLRP3,PSD-95,and SYN related proteins and mRNA.HE and Golgic stai-ning were used to observe the pathological changes in the third ventricle,hippocampus,and neuronal synap-ses.Results Compared with the control group,the depression-like behaviors of the model group rats were significant.The expression of IL-1β,TLR4,and NL-RP3 in the hippocampus increased,while the expres-sion of PSD-95 and SYN decreased.Activation of NL-RP3 inflammasomes led to "sleeve like" pathological changes in the third ventricle,with hippocampal neu-rons undergoing apoptosis and significant damage to neuronal synaptic plasticity.Compared with the model group,after intervention with CCJJY,the expression of ROS,IL-1β,TLR4,and NLRP3 decreased,while the expression of AANAT,5-HT,PSD-95,and SYN in-creased.Pathological damage to the third ventricle and hippocampal neurons was repaired.Conclusion The CCJJY improves hippocampal synaptic plasticity dam-age in depression by regulating the TLR4/NLRP3 sig-naling pathway to inhibit central oxidative stress.

Following extensive interdisciplinary research and development over several years,mechanical circulatory support devices(MCSD),including ventricular assist device(VAD)and total artificial heart(TAH),are now established as vital treatment options for patients with advanced heart failure.These devices have proven to be crucial in assisting or replacing a failing heart,offering patients a new lease of life and improving their quality of life.Currently,mechanical circulatory support(MCS)has become a well-recognised,long-term treatment option for patients who are unable to undergo heart transplantation due to donor organ shortages or contraindications.Given their continuous availability independent of donor organ limitations,these devices are poised to play an increasingly vital role in the future of medicine.This article aims to summarize the evolution,clinical applications,categorization,and potential complications of MCSD.

Yanchi Tan sheep,a specialty of Ningxia,China,is famous for its excellent meat quality,but the detailed mechanisms of its muscle development and meat quality formation are still unclear.In or-der to preliminarily investigate the unique molecular mechanisms in the muscle development of the sheep,the present study was carried out to collect the longest dorsal muscle(LDM)samples from 6-month-old and 12-month-old female Tan sheep,and we screened the genes and long non-coding RNA(lncRNAs)that may play important roles in regulating the muscle development and meat quality formation through transcriptome sequencing(RNA-seq).The results showed that a total of 504 mRNAs and 1,483 lncRNAs were detected between the two groups of LDMs,with significant differences(P＜0.05).And we also pre-dicted 103 potential lncRNA-mRNA cis-regulatory relationship pairs with significant differences(P＜0.05).Skeletal muscle development-related genes such as MSTN,CDKN1A,FHL1 and skeletal muscle metabolism-related genes such as LPL and SCD were subsequently screened based on the functional anal-ysis of differentially expressed mRNA.Based on the functional analysis of differentially expressed lncRNA target genes,13 lncRNAs potentially related to muscle development(LNC.17926.1,LNC.981.1,LNC.16284.1,etc.)and 8 lncRNAs potentially related to skeletal muscle metabolism(LNC.15496.1,LNC.18149.1,etc.)were identified.5 lncRNAs and 4 mRNAs expressed in both groups were randomly selected for qPCR validation experiments,and their results were consistent with RNA-seq,which corrob-orated with the reliability of the sequencing results.This study lays a solid foundation for future investiga-tions of muscle development,meat quality formation mechanism and molecular breeding in Tan sheep,and provides a scientific basis for improving the meat production performance of other domestic sheep breeds.
