While the development of multi-campus hospitals is conducive to promoting the expansion and equal distribution of high-quality medical resources and improving the overall medical quality of municipalities, the model puts forward high requirements for the capabilities of integrated operation and management of public hospitals. As key part of health services and the higher medical education system, facing the multi-campus hospital reform, hospital affiliated to colleges and universities should carry out rearrangements in both medical and educational aspects at the same time. Shanghai Sixth People's Hospital affiliated to Shanghai Jiao Tong University School of Medicine has made substantial progress in integrated and homogenized management since the integration of the Lingang campus as a whole into the parent hospital in 2021. The department of undergraduate clinical medical education has analyzed the difficulties in teaching management and talent cultivation in the multi-campus system during the rearrangement process, forming a coordinated management mechanism for undergraduate clinical medical education within campuses under the concept of "homogeneity-difference-collaboration". This article may provide a reference for enriching multi-campus hospital management practice and improving the quality of undergraduate clinical medical education in hospitals affiliated to colleges and universities.

Aim To investigate the possible mechanism of action of Qingjie Huagong decoction(QJHGD)on acute lung injury(ALI)associated with severe acute pancreatitis(SAP)using network pharmacology,and to verify it by animal experiments.Methods The TC-MSP,BATMAN-TCM,ETCM,and SwissTargetPredic-tion databases were searched to obtain the action tar-gets of the blood-entering active ingredients of each drug in the QJHGD.The GeneCard database was searched to obtain SAP-ALI disease targets.The drug targets and disease targets were intersected to obtain common targets.Subsequently,the common targets were analyzed by STRING database and Cytoscape 3.7.1 software for protein interaction network analysis.GO and KEGG enrichment analysis was performed with the help of DAVID database.Finally,the key signa-ling pathways were verified by animal experiments.Results A total of 28 active ingredients were screened out for the treatment of SAP-ALI with 42 common tar-gets.PPI network analysis showed that STAT3,IL-6,and TGFB1 might be core targets;GO and KEGG en-richment analysis mainly involved cell proliferation,PI3K/AKT signaling pathways,etc.Animal experi-ments confirmed that QJHGD could improve the pathol-ogy of pancreas and lung tissues in SAP-ALI rat mod-el,down-regulate the expression levels of α-amylase,lipase,IL-1 β,IL-6,and TNF-α in serum,and down-regulate the expression levels of proteins and mRNAs related to PI3K/AKT1 signaling pathway in lung tis-sues.Conclusion QJHGD synergistically treats SAP-ALI through multi-component,multi-target,and multi-pathway,with a mechanism that may be related to the inhibition of PI3K/AKT signaling pathway activation.

Ischemic stroke(IS)is a devastating neurological disease commonly around the world.Although modern medicine has recognized the confined mechanisms in the pathological process of cerebral ischemia,it has never been enough for the treatment of IS.Recent studies have confirmed the vital role of mitochondrial dysfunction in neuronal injury after cerebral ische-mia,thereby exerting a potential target for prevention and treat-ment of IS.Herein,we review the main molecular mechanisms of neuronal injury and death by mitochondrial dyshomeostasis under the condition of ischemia/hypoxia,especially mitochon-drial permeability transition pore opening,oxidative stress and apoptotic signaling.Given remodeling of mitochondrial function as a new idea for the management of IS,some emerging strate-gies containing mitochondrial antioxidant,mitophagy regulation and mitochondrial transfer also raise concern in this paper.

Objective To investigate the clinical effect in treating AO type B and C distal radius fractures with modified Henry approach.Methods Retrospectively analysis of 20 patients with AO type B and C distal radius fractures between June 2021 and May 2022,they were treated by modified Henry approach.There were 6 males and 14 females,aged from 35 to 78 years old,8 patients on the left and 12 on the right.The patients'general data,fracture healing time,postoperative complica-tions,last-time follow up radiographic parameters(volar inclination angle,ulnar deviation angle and radius height),wrist range of motion,range of forearm rotation and functional outcoming of the wrist joint according to Mayo scoring were observed of each patient.Results All patients were followed-up,the time was(13.3±2.3)months,ranged from 12 to 18 months.All the fractures were healed,the fracture healing time was(12.6±2.5)weeks,ranged from 10 to 16 weeks.There were no complications such as poor wound healing,incision infection,iatrogenic median nerve injury,delayed union,nonunion and malunion during the post-operative follow up.According to the X-ray measurement in the last-time follow up,the volar inclination angle was(11.4±4.0)°,the ulnar deviation angle was(20.9±2.2)° and the radius height was(10.3±1.2)mm.The wrist range of motion was(65.3±5.8)° for volar flexion,(60.2±4.2)° for dorsal extension,(37.8±4.1)° for ulnar deviation,(27.0±3.7)° for radial deviation.The range of forearm rotation was(80.4±4.1)° for pronation,(78.6±3.7)° for supination.According to Mayo scoring,the wrist function was evaluated as excellent in 12 cases,good in 6 cases and fair in 2 cases,the excellent and good rate was 90％.Con-clusion Modified Henry approach can better expose the ulnar and volar fragments in distal radius,especially useful for reduct-ing the distal radius with complex bi-columnar fractures.

Objective To investigate the regulatory effect of swimming exercise(SE)on lipid metabolism in nonalcoholic fatty liver disease(NAFLD)mice.Methods A total of 27 C57BL/6J mice were divided into the control group(normal diet),high fat diet(HFD)group and HFD+SE group,with 9 mice in each group.Twelve weeks later,liver tissues were collected for untargeted lipidomics detection by LC-MS.Dimensional statistical analysis of lipidomics profiles was carried out by constructing OPLS-DA model,and combined with the t-test,the lipids with OPLS-DA VIP>1,P<0.05 were screened out from all samples as significantly different lipids.Results There were 81 different lipids between HFD group and the control group;and there were 27 different lipids between HFD+SE group and HFD group.The different lipids mainly belong to glycerides,glycerophospholipids and sphingomyelins.Conclusion Lipid metabolism profile of NAFLD mice has been changed,and swimming exercise can improve lipid metabolism of NAFLD mice.

Objective To observe the impact of cold circulation liquid temperature on ablation focus morphology of microwave ablation(MWA)for in vitro porcine liver tissue.Methods Twenty in vitro fresh porcine liver blocks were randomly divided into ice water circulation group(group A)and normal temperature circulation group(group B),respectively.Ten target ablations in each subgroups in group A and group B,i.e.A1 and B1(50 W,1 min),A2 and B2(50 W,5 min),A3 and B3(60 W,1 min),A4 and B4(60 W,5 min),A5 and B5(70 W,1 min)as well as A6 and B6(70 W,5 min)subgroups were performed using different ablation power(50,60,70 W)and ablation time(1,5 min),respectively.Then the morphology indexes of ablation foci,including longitudinal diameter(LD),transverse diameter(TD),roundness index(RI)and volume(V)were compared between subgroups in group A and B,also among subgroups within group A and B.Results Under the same ablation power and time,LD of ablation foci in subgroups of group A were all smaller than those of group B(all P＜0.05).Significant differences of RI of ablation foci were found between A1 and B1,A2 and B2,A4 and B4,A5 and B5 as well as A6 and B6 subgroups(all P＜0.05),but not between A3 and B3 subgroups(P＞0.05).However,the main effect of cold circulation liquid temperature on ablation focus TD(F=1.125)nor V(F=3.332)was not significant(both P≥0.05).Under the same cold circulation liquid temperature,significant differences of the morphology indexes of ablation foci were detected between A1 and A2,A3 and A4 as well as A5 and A6 subgroups,also between corresponding subgroups in group B(all P＜0.05).Conclusion During MWA for in vitro porcine liver tissue under constant ablation power and time,taken ice water as the cold circulation liquid was benefit to ablation focus shaped spherically.With the extension of ablation time,the larger the ablation focus,the higher the RI.

Objective:To analyze the clinical characteristics,treatment,and prognosis of adult patients with early T-cell precursor acute lymphoblastic leukemia/lymphoma(ETP-ALL/LBL).Methods:Clinical data of 113 T lymphoblastic leukemia/lymphoma(T-ALL/LBL)patients from January 2006 to January 2019 were collected from three hematology research centers,including Peking University Third Hospital,the First Medical Center of Chinese PLA General Hospital and Institute of Hematology and Blood Diseases Hospital,Chinese Medical University.The clinical characteristics and prognosis of ETP-ALL/LBL patients were analyzed compared with non-ETP-ALL/LBL patients.Results:In 113 T-ALL/LBL patients,13 cases(11.5％)were diagnosed as ETP-ALL/LBL,including 11 males,with a median age of 28(18-53)years.Compared with non-ETP-ALL/LBL patients,there were no significant differences in age,sex,incidence of large mediastinal mass,clinical stage,international prognostic index(IPI)score,white blood cell(WBC)count and lactate dehydrogenase(LDH)level among ETP-ALL/LBL patients.Among 13 ETP-ALL/LBL patients,9 cases(69.2％)achieved complete remission(CR),and there was no statistically significant difference in response rate induced by chemotherapy between ETP-ALL/LBL patients and non-ETP-ALL/LBL patients.Among patients who received chemotherapy without allogeneic hematopoietic stem cell transplantation(allo-HSCT),ETP-ALL/LBL group had a worse 5-year overall survival(OS)rate compared with non-ETP-ALL/LBL group(0 vs 7.1％,P=0.008),while in patients with allo-HSCT,there was no significant difference for 5-year OS rate between the two group(37.5％vs 40.2％,P＞0.05).Multivariate Cox regression analysis showed that CR after induction therapy,allo-HSCT,and LDH level were independent prognostic factors affecting T-ALL/LBL patients.Conclusion:No significant difference in response rate induced by chemotherapy is observed between ETP-ALL/LBL and non-ETP-ALL/LBL patients.Allo-HSCT consolidation after induction of remission therapy may have significant favorable influence on OS for patients with ETP-ALL/LBL.

Objective:To establish a graded method to avoid mean fluorescence intensity(MFI)threshold of HLA Class I antibodies corresponding antigen,and the HLAMatchmaker program has been used to select the minimum mismatch value of donor-patient epitopes.Evaluate the application value of combining both methods in selecting HLA compatible platelets(PTL)for patients with immune platelet transfusion failure(IPTR)in improving platelet the corrected count increment(CCI).Methods:A total 7 807 PLT cross-matching compatible were performed by the solid-phase red cell adherence(SPRCA)method for 51 IPTR patients.The Luminex single antigen flow cytometry was used to detect HLA Class I antibodies in patients,and detected the MFI value for different specificity antigens of HLA Class I antibodies,was graded into strong positive group(MFI＞4 000,level 1),medium positive group(1 000＜MFI 4 000,2),weak positive group(500＜MFI≤1 000,3),and one negative control group(MFI≤500).The results of 7 807 SPRCA their negative/positive reaction wells were enrolled and statistically analyzed in different grades and the four groups,the statistical differences between the four groups were compared.Multiple applications for the select HLA Class I compatible donor events were made for patients in two cases,and HLAMatchmaker program was used to calculate the number of HLA Class I epitopes mismatches between the donors and patients.The donor with the minimum number of epitopes mismatches was selected,while avoiding the corresponding antigens of HLA Class I antibodies in levels 1 and 2,the provision of HLA compatible platelets for IPTR.After the transfusions,the CCI value of the platelet transfusion efficacy evaluation index was calculated,and the clinical evaluation of the transfusion effect was obtained through statistical analysis.Results:There were statistically significant differences in the positive results of SPRCA immunoassay among the strong positive group,medium positive group,and weak positive group of 51 IPTR patients with different specific of HLA-I class antibodies and corresponding antigens(all P＜0.001).The positive results showed a range from high to low,with strong positive group＞medium positive group＞weak positive group.There were a statistical difference among between the strongly positive or moderately positive groups and the negative control group(P＜0.001).There was no statistical difference between the weakly positive group and the negative control group(P＞0.05).The strong positive group was set as the corresponding specific HLA Class I site corresponding antigen grade 1 avoidance threshold,the medium positive group as the grade 2 avoidance thresholds,and the weak positive group as the grade 3 avoidance threshold.In the case of donor platelet shortage,it is not necessary to avoid the weak positive group.Avoiding the strategy of donor antigens and HLAMatchmaker program scores≤7 corresponding to HLA Class I antibodies of levels 1 and 2,with CCI values＞4.5 × 109/L within 24 hours,can obtain effective clinical platelet transfusion conclusions.Conclusion:When selecting HLA Class I compatible donors for IPTR patients,the grading avoids HLA Class I antibodies corresponding to donor antigens,and the donor selection strategy with the minimum scores of HLAMatchmaker program is comprehensively selected.The negative result confirmed by platelet cross-matching experiments has certain practical application value for improving platelet count in IPTR patients.

Objective:To screen interleukin(IL)-1β secretion-related membrane transporters by macrophage experiment in vitro and conventional knockout mice.Methods:THP-1 cell line was differentiated to obtain human THP-1-derived macrophages,and the primary macrophages were obtained from human peripheral blood.FVB wild-type mice with the same sex and age were used as the controls of MRP1 knockout mice.The macrophages in abdominal cavity and bone marrow of mice were cultivated.The cells were treated with ABCC1/MRP1,ABCG2/BCRP,ABCB1/P-gp,OATP1B1,and MATE transporter inhibitors,then stimulated by lipopolysaccharide and adenosine triphosphate.The secretion level of IL-iβ was detected by ELISA,Western blot,and immunofluorescence.Results:After inhibiting ABCC1/MRP1 transporter,the secretion of IL-1β decreased significantly,while inhibition of the other 4 transporters had no effect.In animal experiment,the level of IL-1 β secreted by macrophages in bone marrow of MRP1 knockout mice was significantly lower than control group(P＜0.05).Conclusion:ABCC1/MRP1 transporter is a newly discovered IL-1β secretion pathway,which is expected to become a new target for solving clinical problems such as cytokine release syndrome.

Objective:To explore the clinical correlation and prognostic value of the Albumin-Bilirubin(ALBI)score in children with secondary hemophagocytic syndrome(sHLH).Methods:A retrospective analysis was conducted on the data of children's sHLH cases clearly diagnosed in the Affiliated Hospital of Zunyi Medical University from January 2012 to March 2023.Survival analysis was conducted according to the ALBI classification.Spearman correlation analysis was conducted between the ALBI score and clinical indicators.The Receiver Operating Characteristic(ROC)curve was used to evaluate the ALBI score,select the best cutoff value,and evaluate the accuracy of prognostic prediction value.Kaplan-Meier method was used to draw the survival curve.Log-rank method was used to compare the differences of survival curve between groups.Cox regression was used for prognostic analysis and restricted cubic spline curves used to calculate the relationship between ALBI scores and the risk of death in children with sHLH.Results:A total of 128 children with sHLH were included in this study,with a median age of 38(13.25,84)months.There were 70 males(54.69％)and 58 females(45.31％).The survival analysis results of ALBI grading showed that the survival rate of HLH patients with ALBI grade 3 was significantly lower than those with ALBI grades 1 and 2.Spearman correlation analysis results showed that ALBI score was positively correlated with splenomegaly,respiratory failure,disseminated intravascular coagulation(DIC),pulmonary hemorrhage,gastrointestinal hemorrhage,central nervous system involvement,ALT,AST,TG,LDH,PT,APTT,and SF(the correlation coefficients are:r=0.181,0.362,0.332,0.221,0.351,0.347,0.391,0.563,0.180,0.448,0.483,0.37,0.356),and was negatively correlated with HB,PLT,and FIB(the correlation coefficients are:r=-0.321,-0.316,-0.423),but was not significantly correlated with EBV infection,fungal infection,hepatomegaly,and ANC(P＞0.05).Using the ROC curve,the cutoff value of ALBI was-1.76.Single factor Cox regression analysis results showed that HB＜90 g/L,ALT ≥ 80 U/L,AST≥200 U/L,LDH ≥1 000 U/L,PT ≥20 s,APTT≥40 s,FIB＜1.5 g/L,ALBI ≥-1.76,combined pulmonary hemorrhage,DIC,central nervous system involvement,gastrointestinal bleeding,and not using blood purification may be the prognostic risk factors for children with sHLH(P＜0.05).Multivariate Cox regression results showed that FIB＜1.5 g/L(HR=2.119,95％CI:1.028-4.368),ALBI≥-1.76(HR=2.452,95％CI:1.233-4.875),and central nervous system involvement(HR=4.674,95％CI:2.486-8.789)were independent risk factors affecting prognosis,while blood purification(HR=0.306,95％CI:0.153-0.612)was an independent protective factor for prognosis.The application of restricted cubic splines shows that the risk of death increases with the increase of ALBI score.The area under the ROC curve(AUC)of the ALBI score for predicting the risk of 1-week,2-week,4-week,and overall mortality were 0.825,0.807,0.700,and 0.693,respectively,indicating good predictive performance for early mortality risk.According to subgroup analysis results of clinical manifestations,compared with the ALBI＜-1.76 group,ALBI≥-1.76 was associated with age ≤2 years,EBV infection,HLH-1994/2004 treatment,concomitant respiratory failure,and ANC≤1.0 × 109/L,HB＜90 g/L,PLT＜100 × 109/L,TG≥3.0 mmol/L,LDH ≥ 1 000 U/L,APTT≥40 s,and FIB＜1.5 g/L(P＜0.05).Conclusion:The ALBI score is related to the clinical characteristics and laboratory indicators of sHLH,and can be used as a beneficial indicator for assessing the prognostic risk of sHLH in children.It has good accuracy and clinical application value in predicting the prognosis of sHLH in children.
