Objective To investigate the detection rate and related influencing factors of gastrointestinal diseases in grass-roots personnel.Methods A total of 481 grass-roots personnel were enrolled and examined by magnetic-controlled capsule endoscopy(MCCE).Multivariate logistic regression were used to analyze the influencing factors of gastrointestinal diseases detected by MCCE.Results All personnel completed MCCE,and gastrointestinal diseases were detected in 154(32.0%)cases,including 106 cases of erosive gastritis,25 cases of chronic atrophic gastritis,17 cases of digestive tract polyp,16 cases of gastric ulcer,5 cases of reflux esophagitis,4 cases of cardia,1 case of duodenitis,and 1 case of enteritis.Gastrointestinal diseases was correlated with special operation posts,long-term tasks within recent 6 months,abdominal distension,belching,nausea and vomiting,diarrhea and other symptoms(all P＜0.05).Multivariate logistic regression analysis showed that the risk factors of gastrointestinal diseases were working in special operation posts,performing long tasks within 6 months,belching,nausea and vomiting symptoms(all P＜0.05).Conclusion The overall detection rate of gastrointestinal diseases(mainly acid related diseases)is relatively high,and its incidence is closely related to working in special operation posts and performing long-term tasks within recent 6 months.Personnel working in special operation posts should be more alert to gastrointestinal diseases.Gastrointestinal symptoms have reference value for the prediction of lesions,but more attention should be paid to the identification of functional gastrointestinal diseases with endoscopy.

Objective To investigate the systemic immune-inflammation index(SII),albumin to globulin ratio(AGR),and high-sensitivity C-reactive protein(hs-CRP)in patients with ulcerative colitis(UC)compli-cated by Epstein-Barr virus(EBV)infection,and to evaluate their diagnostic value in UC complicated by EBV infection.Methods A total of 237 patients with UC admitted to the hospital from February 2024 to Septem-ber 2024.Patients were divided into a complicated group(150 cases)and a control group(87 cases)based on EBV-DNA test results.The counts of neutrophils,lymphocytes,and platelets,as well as the levels of albumin(ALB),globulin,hs-CRP,and erythrocyte sedimentation rate(ESR)were collected from the patients'routine blood tests,and the parameters of SII and AGR were calculated.Spearman correlation test was used for corre-lation analysis.Multivariate binary Logistic regression was used to analyze the influencing factors of EBV in-fection in UC patients,and receiver operating characteristic(ROC)curve was used to evaluate the diagnostic value of individual and combined detection of various indicators.Results There were statistically significant differences in disease activity,lesion range,ALB,AGR,ESR,hs-CRP,and SII between the complicated group and the control group(P<0.05).Correlation analysis showed that the positive copy number of EBV-DNA in the complicated group was positively correlated with disease activity,hs-CRP,and SII(P<0.05),and nega-tively correlated with ALB and AGR(P<0.05).Multivariate binary Logistic regression analysis indicated that SII and AGR were independent influencing factors for UC patients complicated by EBV infection.The combined detection of ALB,AGR,SII,hs CRP,ESR and various indicators has certain predictive value for UC patients with EBV infection.The area under the curve of the combined detection of ALB,AGR,SII,hs-CRP,ESR and the AUC of the combined detection of SII,AGR,hs-CRP were the largest,and the sensitivity and specificity were also high.Conclusion SII and AGR are independent influencing factors for UC patients com-plicated by EBV infection.The combined detection of SII,AGR,and hs-CRP has good diagnostic value for UC complicated by EBV infection and could serve as valuable biomarkers for evaluating UC complicated by EBV infection.

Objective:To investigate the etiological distribution of severe community-acquired pneumonia (CAP) in children in Hebei Province.Methods:The nasopharyngeal swab samples and clinical data from 314 children with severe pneumonia were retrospectively analyzed between January 2014 and January 2016.Results:Among the 314 children, 298 (94.94%) showed positive result for pathogens in their nasopharyngeal swab samples, with 246 cases (78.34%) of multiple pathogens, predominantly mixed viruses and bacteria (206 cases, 65.61%). A total of 848 strains of pathogens were detected, including 483 strains (56.96%) of viruses, predominantly respiratory syncytial virus with 97 strains of subtype A and 86 strains of B. Bacteria and atypical pathogens ( Mycoplasma pneumoniae) had 365 strains (43.04%), mainly Streptococcus pneumoniae (220 strains) and Haemophilus influenzae (119 strains). The detection rate of pathogens was higher in children under one year of age ( χ2=21.389, P<0.001). There were no significant differences in different seasons, but the detection rates of respiratory syncytial virus A, respiratory syncytial virus B, and Streptococcus pneumoniae were higher in autumn, winter, and spring, respectively, with statistically significant differences ( χ2=22.205, P<0.001; χ2=37.874, P<0.001; χ2=11.380, P=0.009). Conclusions:Nasopharyngeal swab sample testing in children with severe pneumonia typically shows a coexistence of viral and bacterial pathogens, with detection rates varying among different age groups and seasons. Nasopharyngeal swab sample testing for pathogens provides valuable references for the identification of clinical pathogens.

ObjectiveMetabolomics was used to reveal the mechanism of Aconiti Lateralis Radix Praeparata（ALRP） in attenuating toxicity by processing from the aspects of amino acid metabolism， oxidative stress and energy metabolism by analyzing multiple metabolic pathways. MethodTwenty-four rats were randomly divided into control group， raw group and processed group， 8 rats in each group. The raw and processed group were given with 0.64 g·kg^-1 of raw ALRP and processed ALRP respectively every day， the control group was given with an equal amount of normal saline once a day. After continuous administration for 7 days， the urine， serum and heart tissue of rats were collected. Pathological examination of the heart was carried out using hematoxylin-eosin（HE） staining， and the activities of lactate dehydrogenase（LDH） and creatine kinase-MB（CK-MB） in serum and cardiac tissues were detected by microplate assay and immunoinhibition assay. The effects of ALRP on rat heart before and after processing were compared and analyzed. Ultra performance liquid chromatography-quadrupole-time-of-flight mass spectrometry（UPLC-Q-TOF-MS） was used to perform urine metabolomics analysis， and multivariate statistical analysis was used to screen for differential metabolites related to ALRP in attenuating toxicity by processing， and pathway enrichment analysis was carried out to explore the processing mechanism. ResultHE staining showed that no obvious pathological changes were observed in the heart tissue of the control group， while obvious infiltration of inflammatory cells such as plasma cells and granulocytes was observed in the heart tissue of the raw group， indicating that the raw ALRP had strong cardiotoxicity. There was no significant difference in HE staining of heart tissue between the processed group and the control group， indicating that the toxicity of ALRP was significantly reduced after processing. Compared with the control group， the activities of LDH and CK-MB were significantly increased in serum and heart tissue of the raw group， and those were significantly decreased in serum and heart tissue of the processed group， suggesting that the myocardial toxicity of processed ALRP was reduced. A total of 108 endogenous differential metabolites associated with the raw ALRP were screened using multivariate statistical analysis in positive and negative modes， of which 51 differential metabolites were back-regulated by the processed ALRP. Biological analysis of the key regulatory pathways and associated network changes showed that the pathways related to toxicity of ALRP mainly included tryptophan metabolism， arginine and proline metabolism， phenylalanine metabolism， aminoacyl-tRNA biosynthesis， alanine， aspartate and glutamate metabolism， etc. The metabolic pathways related to the attenuation of processed ALRP mainly included aminoacyl-tRNA biosynthesis， tryptophan metabolism， phenylalanine， tyrosine and tryptophan biosynthesis， phenylalanine metabolism and caffeine metabolism. ConclusionThe processing technology of ALRP in Guilingji can significantly attenuate the cardiotoxicity of raw products， the mechanism mainly involves amino acid metabolism， oxidative stress and energy metabolism， which can provide experimental bases for the research related to the mechanism of toxicity reduction of ALRP by processing and its clinical safety applications.

Health technology assessment(HTA)is an important tool to inform health decision-making.Although highly related to ethical issues in the context of HTA,equity has attracted much attention from the academia,a consensus has not yet been reached on how to define and evaluate equity in China and abroad.It introduces the concept of equity,pointes out the necessity to realize health equity and the reflection of equity in healthcare sector,and further elaborates four ways to consider equity,and described the official practice of equity in HTA at home and abroad.It proposes several suggestions for China's HTA:considering equity in HTA and the discussion of equity should depend on specific decision-making scenarios;clarifying what health measurement perspective should be adopted before measuring health equity;paying attention to the value judgment of equity adopted by various stakeholders;conducting basic researches on the general population's preference for health measurement perspectives and value judgments of equity in China in a gesture to improve the evaluation system of equity in HTA.

Constructing a multi-tiered healthcare security system can meet the diverse and individualized healthcare service demand of the general public.Public hospitals,as the main providers of healthcare services in China,effectively integrate with commercial health insurance,which can accelerate the implementation of high-quality healthcare services,promote innovative development,and optimize product coverage and operational efficiency for commercial health insurance,achieving a win-win situation.Taking Shanghai as the research object,it analyzes the supply and demand status of multi-tiered healthcare security in Shanghai based on population characteristics,economic level,healthcare resources,and policy environment.It identifies the difficulties in the current collaboration between public hospitals and commercial insurance.Finally,it proposes exploring the expansion of independent development space for specialized services,improving the level of coordination between commercial insurance institutions and public hospitals in health management services,promoting the management and sharing of data,strengthening the protection of innovative medicines and devices by commercial insurance,in order to promote the coordinated development of commercial insurance and public hospitals.

Based on on-site research in Shanghai,it takes a supply-side perspective to examine the current status of cooperation between Private Health Insurance(PHI)and the pharmaceutical industry.It discusses the issues existing in the cooperation and proposes policy recommendations for their coordinated development.It identifies three main cooperation models and products,which are the public-private integrated product"Hui Min Bao",the special drug insurance led by insurance companies,and the disease insurance for patients led by pharmaceutical enterprises.However,these models commonly face challenges such as the limited policy support,a lack of standardized cooperation between the two sectors,insufficient information and data exchange,immature innovative payment models,and difficulties in the application of innovative drugs.It argues that the key to coordinated development lies in leveraging the strategic purchasing power of PHI,devising rational payment strategies and standards to achieve a win-win situation for insurers,enterprises,healthcare providers and patients.Therefore,policy recommendations are proposed from the perspectives of establishing mechanisms,breaking barriers,strategic procurement,and supporting measures.
