Aim To investigate the effect of Rtv(a P-gp inhibitor and inducer)on the pharmacokinetics of Y101(P-gp substrate)via P-gp.Methods In short-term studies,rats received a single dose of Rtv,where-as in long-term studies they received continuous dosing for seven days.Following this treatment,Y101 was o-rally administered to analyze its blood concentration in rats.Subsequently,the mechanism by which Rtv af-fected Y101 pharmacokinetics was investigated through the everted gut sac model(in vitro),cellular uptake studies,and so on.Results Short-term administra-tion of Rtv significantly increased Y101's AUC,liver-to-plasma partition coefficient,the everted gut sac model(in vitro),and cellular accumulation.Although long-term Rtv treatment had no effect on Y101 pharma-cokinetics or hepatic distribution,it markedly reduced Y101 cellular accumulation in Caco-2 cells,concomi-tant with an upregulation of P-gp expression.Conclu-sions Short-term Rtv administration acts as a compet-itive P-gp inhibitor,enhancing Y101 intestinal absorp-tion and hepatic distribution.In contrast,the plasma pharmacokinetics and hepatic distribution of Y101 are not altered after long-term administration of Rtv,po-tentially attributable to Rtv's dual modulatory effects on P-gp involving both induction and inhibition.Hence,the potential Rtv and Y101 interaction should be close-ly monitored in the clinic.

Objective:This article aims to investigate the effect of optimized prehospital emergency intervention com-bined with green channel on prehospital delay and prognosis of patients with acute cor pulmonale(ACP).Methods:This randomized controlled study enrolled 116 ACP patients admitted in Hai'an People's Hospital between January 2021 and January 2023.They were divided into control group(n=58,routine emergency nursing procedure)and in-tervention group(n=58,optimized prehospital emergency intervention combined with green channel program).After 1-month intervention,therapeutic effect,emergency indicators,cardiopulmonary function,quality of life and incidence of complications were compared between two groups.Results:After 1-month,total effective rate of intervention group was significantly higher than that of control group(84.48％vs.62.07％,P=0.006).Com-pared with patients in control group,those in intervention group had significant lower emergency stay time[(19.80±1.90)min vs.(27.92±1.62)min],triage assessment time[(2.01±0.18)min vs.(2.99±0.17)min]and transport time[(33.69±1.90)min vs.(35.91±1.74)min],and significant higher left ventricular ejection frac-tion(LVEF)[(59.85±1.36)％vs.(46.97±1.79)％],forced expiratory volume in one second(FEV1)[(3.66±0.17)L vs.(3.00±0.17)L],scores of nursing quality and each domain of Quality of Life Instruments for Chro-nic Diseases-Chronic Pulmonary Heart Disease(QLICD-CPHD)(P＜0.001 all).Incidence of complications in intervention group was significantly lower than that of control group(5.17％vs.17.24％,P=0.039).Conclusion:Optimized prehospital emergency intervention combined with green channel has significant clinical effect on ACP patients.It could reduce emergency,triage and transport time,improve nursing quality and quality of life,enhance cardiopulmonary function,and reduce the incidence of complications.

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.

This study used kidney metabolomics to investigate the underlying mechanisms of Guilingji (GLJ) on mild cognitive impairment (MCI) rats. The rats were randomly divided into 6 groups (n = 8), i.e., control group, model group, positive drug (Ginkgo biloba tablet, donepezil) group, GLJ group (low and high dose group). The MCI rat model was replicated using subcutaneous injection of D-galactose into the back of the neck along with a semi-high-fat diet for a total of 8 weeks, and drug was administered from the 5th week for 4 weeks. The kidney function and renal pathological changes of each group of rats were tested. And LC-MS based kidney metabolomics coupled with multivariate data analysis were conducted to explore the potential biomarkers, and corresponding metabolic pathways were then determined. After administration of GLJ, the level of urea nitrogen was decreased compared with those of the model group, and the abnormalities of morphology in kidney tissues were improved. The positive drugs (ginkgo biloba tablet and donepezil) had no significant modulating effect on renal function indexes. Ginkgo biloba tablet can lessen the pathological injury of kidney tissue, and donepezil had no improvement on renal histopathology. A total of 23 MCI related differential metabolites were identified in kidney, and 17 metabolites were signifcantly restored by GLJ compared with those of the model group. Additionally, we found that the cysteine and methionine metabolism, nicotinate and nicotinamide metabolism, taurine and hypotaurine metabolism, glycerophospholipid metabolism were significantly involved in the regulatory effect of GLJ. The results illuminate the "cong shen zhi nao" mechanism of GLJ, and also provide a research basis for the clinical use of GLJ for the treatment of MCI. The animal experiment of this study was approved by the Ethics Committee of Shanxi University (approval number: 2020DW121).

The aim of this study was to investigate the virulence determinants and genetic diversity of foodborne Yersinia enterocolitica from Wenzhou.A total of 71 strains of Yersinia enterocolitica were isolated from food and foodborne diarrhea ca-ses in Wenzhou,and their biotypes,serotypes,and drug resistance were analyzed.On the basis of whole genome sequencing,we assessed virulence gene profiles,and performed multilocus sequence typing(MLST)and core gene multilocus sequence typ-ing(cgMLST).A total of 94.4％(67/71)of isolates belonged to biotype 1A,and the highest proportion had serotype lA/O∶5(29.6％,21/71).The sensitivity rates of the isolates to 14 antibiotics exceeded 95.8％.A total of 16 categories and 126 viru-lence genes were identified,with two strains carrying the pYV plasmid and chromosome-related virulence genes.ST3(31.6％,12/38)was the most widespread MLST type,and cgMLST analysis revealed no dense clusters of genotypes except for strains sharing the same ST.In conclusion,pathogenic strains were identified from foodborne Yersinia enterocolitica in Wenzhou and were found to exhibit high genetic polymorphism.Enhanced regulatory supervision is essential to prevent the outbreak of food-borne diseases caused by Yersinia enterocolitica.

Objective To provide a longitudinal evaluation tool based on the frequency of aggressive be-havior for the aggression assessment of schizophrenia patients.Methods The Life History of Aggression was translated and revised to form the Life History of Aggression-Chinese Version(LHA-CV)based on 369 patients diagnosed with schizophrenia in the Chengdu community and compulsory medical insti-tution.The reliability of LHA-CV was analyzed by means of split-half reliability,test-retest reliability and inter-evaluator consistency.The validity was analyzed by item analysis,construct validity and crite-rion validity.Results Item analysis found that LHA-CV had good homogeneity and discriminant validity.Exploratory factor analysis found that the Kaiser-Meyer-Olkin(KMO)test value was 0.80,and the Bartlett's sphericity test χ2=1203.46(P<0.05),and it revealed four factors including non-physical ag-gression,physical aggression,self-directed aggression and antisocial behavior/consequences.The factor loadings for all 11 items were greater than 0.40.Confirmatory factor analysis was performed on the factor model,Chi-square degree of freedom(χ2/df)was 3.61,root mean square error of approxima-tion(RMSEA)was 0.07,goodness-of-fit index(GFI)was 0.92,comparative fit index(CFI)was 0.90,incremental fit index(IFI)was 0.90,and the discriminant validity of each factor was good.The criterion validity test showed the total score of LHA-CV was positively correlated with the aggressive behavior level of MacArthur Community Violence Instrument,the total score of Buss-Perry Aggression Scale,and the score of Antisocial Personality Disorder Subscale of Personality Diagnostic Question-naire-4th Edition Plus(PDQ-4+_ASPD,P<0.05).The Cronbach's α coefficient of non-physical aggres-sion,physical aggression,self-directed aggression,antisocial behavior/consequences and LHA-CV total score were 0.82,0.73,0.74,0.56 and 0.79,respectively.The test-retest reliability,Spearman-Brown split-half reliability and intra-class correlation coefficient of LHA-CV total score were 0.82(P<0.05),0.66 and 0.99,respectively.Conclusion LHA-CV has good reliability and validity,and can be used as an evaluation tool for longitudinally assessing aggressive behavior in schizophrenia patients.

Objective:To understand the status, evaluation methods and risk factors of economic toxicity in patients with head and neck cancer, in order to provide reference for the construction of follow-up intervention programs.Methods:This scoping review was conducted under the Joanna Briggs Institute in Australia guidelines. Relevant studies were searched in PubMed, Embase, Web of Science, Cochrane Library, Scopus, CINAHL, China National Knowledge Infrastructure, Wanfang Database, VIP Database and Chinese Biomedical Literature Database. Chinese and English literature was screened and summarized from inception to September 21, 2023.Results:A total of 14 articles were included, and the economic toxicity of patients with head and neck cancer was more serious.The evaluation methods were mainly divided into scale evaluation and database data calculation. The risk factors of economic toxicity in patients with head and neck cancer included three aspects: demographic factors such as young age, low education and low income; disease and treatment-related factors such as tumor location in larynx/hypopharynx, current/past use of tube feeding, advanced tumor/distant metastasis; social support factors such as insufficient social security, and so on.Conclusions:Future studies should pay more attention to economic toxicity in patients with head and neck cancer, standardize the selection of assessment tools to reduce heterogeneity, and develop individualized intervention measures for the risk factors of economic toxicity in patients with head and neck cancer, in order to reduce the occurrence of economic toxicity in patients with head and neck cancer.

Hepatitis E virus(HEV)infection is an infectious disease that can lead to acute or chronic hepatitis E and poten-tially liver failure.HEV can invade multiple organ systems outside the liver,thus leading to pathological damage and diverse clinical manifestations.Neurological disorders are the most common extrahepatic diseases associated with HEV infection.The rare associated extrahepatic diseases include renal disorders,hematological disorders,acute pancreatitis,endocrine system dis-eases,and male infertility.Hence,HEV infection should be considered as a systemic disease rather than solely a liver disease.Many reports have described nervous system diseases caused by HEV infection.This article reviews the rare extrahepatic disea-ses and pathogenic mechanisms of hepatitis E,to enhance comprehensive,in-depth understanding of HEV infection,and to provide a reference for early identification and intervention.
