Aim To explore the potential mechanism of action of Codonopsis Poria in the treatment of alco-holic liver disease(ALD).Methods TCMSP and Swiss Target Prediction were used to obtain the active ingredients and targets of Codonopsis Poria;OMMI,DisGeNET and GeneCards databases were used to obtain the targets of ALD;STRING database was used to construct the PPI network;and Bioconductor soft-ware was used to analyze the enrichment of GO and KEGG pathways.Cytoscape 3.7.1 software was used to construct the drug-component-target-disease network of Codonopsis Poria for ALD treatment,and key targets were screened for molecular docking;the effects of Codonopsis Poria on ALD rats were verified by experi-ments.Results The removal of duplicate targets ob-tained 36 chemical components and 529 potential ac-tion targets.GO enrichment analysis:2 245 biological processes,74 cellular components,125 molecular functions.KEGG enrichment analysis:159 signaling pathways,mainly involving PI3K-Akt,MAPK,AGE-RAGE signaling pathways.Molecular docking showed that AKT1,MMP9 and other targets may be the key targets of Codonopsis Poria in the treatment of ALD.Experiments showed that Codonopsis Poria could im-prove the inflammation level of hepatocytes in ALD rats and reduce the levels of TC,TG,AST,ALT and GGT in ALD rats,PCR assay concluded that Codonopsis Po-ria could reduce the expression of PI3 K and AKT,and electron microscopy results showed that Codonopsis Po-ria could affect the autophagy of cells.Conclusions It is initially revealed that Codonopsis Poria may atten-uate inflammatory cell infiltration by affecting the ex-pression of AKT,TNF and MAPK,and it is hypothe-sized that Codonopsis Poria may affect autophagy through the PI3K-Akt signaling pathway,thus treating ALD,which is initially verified by PCR assay to pro-vide a basis for in-depth explanation of the molecular mechanism of Codonopsis Poria medicinal pairs in the treatment of ALD.

Objective:To investigate the clinical characteristics and prognosis of single center adult chronic myeloid leukemia in chronic phase(CML-CP).Methods:Clinical data of 41 adult CML-CP patients in Department of Hematology,Shanghai Fengxian District Central Hospital from January 2015 to May 2021 were retrospectively analyzed.The clinical characteristics and prognosis of patients between＜60 years group and ≥ 60 years group were compared.Results:The 41 patients included 27(65.9％)males and 14(34.1％)females.The median age of the patients was 56(19-84)years,with 22 cases(53.7％)＜60 years and 19 cases(46.3％)≥60 years.Univariate analysis indicated that the proportions of patients with comorbidities,intermediate/high-risk Sokal score,myelofibrosis,and lactate dehydrogenase ≥1 000 U/L were significantly increased in ≥60 years group compared with＜60 years group at initial diagnosis(all P＜0.05).There were no statistical differences in the distribution of sex,ELST score,white blood cell count,platelet count,peripheral blood basophil percentage,peripheral blood eosinophil percentage and bone marrow primitive cell percentage between the two groups(P＞0.05).The proportion of patients taking reduced-dose imatinib in≥60 years group significantly increased(P＜0.001).Patients＜60 years had a higher proportion of molecular biological remission after treatment of tyrosine kinase inhibitors(TKIs)than patients ≥ 60 years(P＜0.001).The incidence of non-hematologic adverse reactions to TKI therapy significantly increased in patients ≥ 60 years(P＜0.001).Multivariate analysis showed that no adverse factors affecting the efficacy and prognosis of TKI.Conclusion:Compared with adult CML-CP patients＜60 years,patients ≥ 60 years gain fewer benefits from TKI treatment and increased adverse reactions.

AIM To investigate the effects of Zuogui Jiangtang Tongmai Recipe on necroptosis pathway in a rat model of type 2 diabetes mellitus(T2DM)complicated with cerebral infarction(CI).METHODS The SD rats were randomly divided into the sham operation group,the model group,the metformin group(0.045 g/kg),and the low,medium and high dose Zuogui Jiangtang Tongmai Recipe groups(6.5,13,26 g/kg),with 9 rats in each group.In contrast to rats of the sham operation group,rats of the other groups were given 4 weeks feeding of high-sugar and high-fat diet combined with intraperitoneal injection of streptozotocin to establish a T2DM rat model with one week stable blood glucose,followed by gavage of corresponding drugs 3 days before the establishment of the middle cerebral artery occlusion(MCAO)model.After 7 days of administration,the rats had their CI injury assessed by mNSS method and TTC staining;their level of blood glucose detected by blood glucose meter;their levels of glycated serum protein,serum TNF-α and IL-1β detected by ELISA;their cerebral mRNA expressions of FADD,RIPK1,RIPK3 and MLKL detected by RT-qPCR;and their cerebral protein expressions of FADD,p-RIPK1,p-RIPK3 and p-MLKL detected by Western blot.RESULTS Compared with the sham operation group,the model group displayed increased levels of blood glucose value,glycosylated serum protein,neurological function score,cerebral infarction volume,cerebral FADD,RIPK1,RIPK3 and MLKL mRNA expressions,cerebral FADD,p-RIPK1,p-RIPK3 and p-MLKL protein expressions,serum TNF-α and IL-1β levels(P＜0.01);and more disordered and morphologically diverse neurons with smaller nucleus.Compared with the model group,the groups intervened with medium or high dose Zuogui Jiangtang Tongmai Recipe,or metformin shared improvement in terms of the aforementioned indices(P＜0.05,P＜0.01);and more neurons with regular morphology neat arrangement,and reduced cell gap.CONCLUSION Zuogui Jiangtang Tongmai Recipe can improve the neurological dysfunction of the rat model of T2DM complicated with CI,which may associate with the inhibited activation of necroptosis signaling pathway.

Objective:To explore the effectiveness and safety of endoscopic ultrasound-guided pancreatic duct drainage (EUS-PD).Methods:A retrospective analysis was conducted on data of 16 patients who underwent EUS-PD because of endoscopic retrograde pancreatography (ERP) failure, poor effectiveness or anatomical changes and couldn't undergo the routine ERP in Nanjing Drum Tower Hospital from June 2018 to July 2022. The technical success of EUS-PD, clinical efficacy and post-procedure adverse events were analyzed.Results:In the 16 patients, there were 14 males and 2 females, with age of 50.69±12.95 years. A total of 19 times of EUS-PD operations were included, 3 of them were rendezvous-assisted endoscopic retrograde pancreatography (RV-ERP), 15 transgastric or transenteric EUS-guided stent placement and 1 was EUS-guided nasopancreatic duct placement. Technical success was achieved in 84.21% (16/19) patients, and among whom 93.75% (15/16) achieved clinical success. The overall incidence of postoperative adverse events was 52.63% (10/19) including 47.37% (9/19) abdominal pain, 15.79% (3/19) fever and 15.79% (3/19) postoperative pancreatitis. All adverse effects were relieved after general conservative treatment and no primary disease or surgery-related death occurred. The mean follow-up was 17.6 (8.2,22.3) months and 93.75% (15/16) of the patients were followed up. By the time of follow-up, 76.92% (10/13) of the patients who had successfully received EUS-PD had no recurrence of abdominal pain or distension.Conclusion:EUS-PD is a safe and effective alternative therapy for those with pancreatic diseases with ERP failure, poor efficacy or anatomical changes.

Objective:To analyze the clinical symptoms and epidemiological characteristics of patients with tsutsugamushi disease (TD) in Utica County, Shiyan City, providing reference for scientific prevention and control of TD.Methods:The information of 57 TD patients admitted to the Department of Infectious Diseases of the People's Hospital of Utica County in Shiyan City from January to December 2022 was collected, including age, gender, occupation, clinical manifestations (tarsus or chigger, high fever, rash and accompanying syndromes), laboratory and imaging test results, and field work and travel history. Blood samples and body crusts were collected, and enzyme-linked immunosorbent assay (ELISA) and polymerase chain reaction (PCR) were used to detect antibodies against Orientia tsugamushi (Ot-Ab-IgM) and Orientia tsutsugamushi (Ot). The scores of each patient were calculated using the TD Diagnostic Scale. A score of ≥8.5 was considered a clinical diagnosis of TD. According to the number of system functional damages (0, 1, 2, ≥3), 57 patients were divided into 4 groups, A, B, C, and D, TD was analyzed for system functional damages of each system.Results:Among the 57 TD patients, 26 (45.61%) were male and 31 (54.39%) were female, and the proportion of patients aged 40 - 79 years was 92.98% (53/57); farmers accounted for 89.47% (51/57). May was the peak of TD incidence, with 19 cases, which accounted for 33.33% (19/57) of the total number of patients affected that year. Fifty-four patients had a history of fieldwork or field trips before the onset of the disease. The incidence of high fever in 57 TD patients was 100.00%(57/57), the detection rate of body scorch or chiggers was 80.70% (46/57), and the incidence rate of rash was 98.25% (56/57); the incidence rate of tsutsugamushi disease triad (accompanied by scabs, high fever, and rash) was 80.70% (46/57); the incidence of eosinophil decline was 100.00%(57/57), and 77.19% (44/57) of TD patients experienced multiple-system functional damage (MSFD). The TD score diagnostic scale for 57 patients ranged from 8.5 to 10.5 points. After being hospitalized for 1 - 5 days, all TD patients experienced a decrease in body temperature to the normal range, and the damage to various systems functional gradually recovered.Conclusions:TD has become one of the most common natural infectious diseases in Utopia County, Shiyan City, Hubei Province. The patients are mainly middle-aged and elderly people, and the triple syndrome is a typical clinical manifestation. Asymptomatic injuries to the blood system, liver and kidneys are the most common.

Patients with severe trauma require an extremely timely treatment and transfusion plays an irreplaceable role in the emergency treatment of such patients. An increasing number of evidence-based medicinal evidences and clinical practices suggest that patients with severe traumatic bleeding benefit from early transfusion of low-titer group O whole blood or hemostatic resuscitation with red blood cells, plasma and platelet of a balanced ratio. However, the current domestic mode of blood supply cannot fully meet the requirements of timely and effective blood transfusion for emergency treatment of patients with severe trauma in clinical practice. In order to solve the key problems in blood supply and blood transfusion strategies for emergency treatment of severe trauma, Branch of Clinical Transfusion Medicine of Chinese Medical Association, Group for Trauma Emergency Care and Multiple Injuries of Trauma Branch of Chinese Medical Association, Young Scholar Group of Disaster Medicine Branch of Chinese Medical Association organized domestic experts of blood transfusion medicine and trauma treatment to jointly formulate Chinese expert consensus on blood support mode and blood transfusion strategies for emergency treatment of severe trauma patients ( version 2024). Based on the evidence-based medical evidence and Delphi method of expert consultation and voting, 10 recommendations were put forward from two aspects of blood support mode and transfusion strategies, aiming to provide a reference for transfusion resuscitation in the emergency treatment of severe trauma and further improve the success rate of treatment of patients with severe trauma.

Objective:To investigate the safety and effectiveness of endoscopic retrograde cholangiopancreatography (ERCP) for the diagnosis and treatment of pediatric pancreaticobiliary maljunction (PBM).Methods:Data of 40 pediatric patients under 14 with PBM diagnosed and treated by ERCP at Department of Gastroenterology, Nanjing Drum Tower Hospital, the Affiliated Hospital of Nanjing University Medical School from November 2012 to September 2022 were collected. PBM types, ERCP-related diagnosis and treatment, adverse events and prognosis were retrospectively analyzed.Results:Nineteen cases were P-B type (joining of common bile duct with pancreatic duct), 17 were B-P type (joining of pancreatic duct with common bile duct), and 4 were complex type. Forty children with PBM underwent 50 ERCP-related operations, among which 48 procedures succeeded. One case failed during cannulation of ERCP, replaced by rendezvous-assisted endoscopic retrograde pancreatography (RV-ERP) afterwards. There were no serious postoperative adverse events such as bleeding, perforation or death. Thirty-four patients (85%) were followed up successfully, among which 14 underwent further surgery and 20 continued conservative treatment.Conclusion:ERCP is the golden standard to diagnose pediatric PBM, and it is also safe and effective treatment for PBM.

Objective·To explore the effect of double homeobox(DUX)protein on the differentiation potential of mouse embryonic stem cells(mESCs)into extraembryonic endoderm(XEN)and the possible mechanism of its action.Methods·Overexpression of DUX cell lines in mESCs was achieved by using a lentiviral system.The proportion of 2-cell-like cells(2CLCs)before and after DUX overexpression was detected by flow cytometry,and the expression of 2-cell stage-specific genes,Dux,zinc finger and SCAN domain containing 4c(Zscan4c),zinc finger protein 352(Zfp352)and murine endogenous retrovirus-L polymerase(MERVL-pol),were detected by real-time quantitative reverse transcription polymerase chain reaction(RT-qPCR).RT-qPCR assay was used to detect the expression of pluripotency factors,nanog homeobox(Nanog),kruppel-like transcription factor 4(Klf4),sex determining region Y-box 2(Sox2),and octamer-binding transcription factor 4(Oct4),in pluripotent state,as well as the expression of signature genes for different germ layers in the differentiated state[endodermal:GATA binding protein 4(Gata4),GATA binding protein 6(Gata6),and sex determining region Y-box 17(Sox17);ectodermal:Nestin and tubulin beta 3 class Ⅲ(Tubb3);mesodermal:heart and neural crest derivatives expressed 1(Hand1),myogenic differentiation 1(Myod1),and kinase insert domain protein receptor(Flk1)].Public RNA sequencing(RNA-seq)data were mined to further clarify the effect of DUX on the differentiation of mESCs into extraembryonic endoderm.Functional and pathway enrichment analyses of differentially expressed genes were performed using Gene Ontology(GO),Kyoto Encyclopedia of Genes and Genomes(KEGG),and gene set enrichment analysis(GSEA)to identify the signaling pathways regulated by DUX.Additionally,an in-depth analysis of existing chromatin immunoprecipitation sequencing(ChIP-seq)data was conducted to explore the potential target genes of DUX.Results·Molecular biology experiments showed that overexpression of DUX could effectively maintain the pluripotency of mESCs,which was consistent with the analysis of public RNA-seq data.Differential gene analysis revealed that endodermal genes were specifically upregulated.After differentiation assay of mESCs,RT-qPCR assay experiments showed that mRNA expression of the XEN marker genes(Gata4,Gata6,Sox17)was significantly upregulated(P<0.001).In contrast,there was no specific change in mesodermal and ectodermal genes.GSEA enrichment analysis indicated that DUX might activate the retinoid metabolism signaling pathway,and the analysis of the ChIP-seq data further revealed the presence of a large number of known retinoic acid receptor motif in DUX-bound peaks,which could activate downstream target genes related to the development of the XEN.Conclusion·DUX has a strong correlation with the retinoic acid signaling pathway and it is predicted to activate the retinoic acid signaling pathway,which could promote the tendency of mESCs toward XEN differentiation.

Objective:To analyze the group heterogeneity of different types of self-management ability of patients with nonalcoholic fatty liver disease (NAFLD) through potential category analysis, and to explore the differences of nursing interventions among different types of people, so as to provide reference for intervention research.Methods:From March to August 2021, NAFLD patients undergoing physical examination and hospitalization in the First Affiliated Hospital of Xinjiang Medical University were selected as the research object by convenience sampling. The General Information Questionnaire, Health Promoting Lifestyle Profile-Ⅱ (HPLP-Ⅱ) and Self-management Behavior Scale for Patients with NAFLD were used to investigate the patients, and the height and weight of the patients were also measured. A total of 1 189 questionnaires were distributed and 1 124 valid questionnaires were recovered.Results:Self-management ability of NAFLD patients were divided into five types, including good self-management group (32.03%) , lack of self-management-medium level psychological cognition group (23.84%) , lack of health promoting behavior group (11.30%) , lack of disease-cognition-life management group (27.31%) , serious lack of self-management-medium level stress group (5.52%) . Taking the good self-management group as a reference, the results showed that age, marital status, occupation, education level, average monthly income, treatment methods, smoking, body mass index (BMI) , sleep quality, and concomitant diseases were the influencing factors that caused the potential category differences of self-management behavior in NAFLD patients, and the differences were statistically significant ( P<0.05) . Conclusions:Each potential category of NAFLD patients' self-management ability has specificity, which suggests that the formulation of nursing interventions for NAFLD patients in the future should be based on the heterogeneity of various types of groups, so as to improve the effectiveness of self-management intervention.

Aim To investigate the mechanism and search for potential biomarkers of ovalbumin ( OVA ) -induced asthma in mice base on lipidomics. Methods A BALB/c mouse model of asthma was prepared by OVA. TNF-α, IL-4, IL-10, IFN-γ levels in BALF and IgE level in serum were measured by ELISA. The inflammatory changes in mouse lung tissue were observed using HE staining. Lipid mediators ( LMs) in lung tissue and serum were quantified with UPLC-MS/ MS strategy. Results IgE level in serum and TNF-α, IFN-γ levels in BALF were higher (P <0.05) of asthmatic mice.Typical inflammatory manifestations were seen in lung tissue of asthmatic mice. A total of 57 lipid mediators were quantified with UPLC-MRM. LMs metabolic profiles differed significantly in serum and lung tissue between asthmatic and normal mice, 17 significantly different LMs were found in lung tissue and 6 LMs were found in serum, and the differential metabolites were produced through the cyclooxygenase (COX), lipoxygenase (LOX) and cytochrome P450 oxidase (P450) metabolic pathways. Conclusions OVA-induced allergic asthma can cause disorder of lip-id mediators, LMs and cytokines are involved in the occurrence and development of asthma. The differential LMs have potential research value as biomarkers for the development of allergic asthma.
