Objective To explore the role of breast/ovarian cancer susceptibility gene 1 associated protein 1(BAP1)in the occurrence and progression of human malignant glioma and the feasibility of BAP1 as a clinical diagnostic marker for malignant glioma.Methods The differential expression of BAP1 in normal and glioma tissue was analyzed based on the GSE4290 and GSE90598 sub-datasets from the gene expression omnibus(GEO)database.Receiver operating characteristic(ROC)curve analysis was conducted to assess the early diagnostic value of BAP1 for malignant glioma.Primary lesion tissues from 28 nonpaired malignant glioma patients and non-tumor brain tissues removed by internal decompression surgery in 5 patients with traumatic brain injury collected independently were collected,and the expression levels of BAP1 were measured using quantitative real-time polymerase chain reaction(qRT-PCR).Specific small interfering RNAs(siRNAs)targeting BAP1 were transiently transfected into U251 cells to further evaluate their interference efficiency.Flow cytometry was employed to analyze changes in the cell cycle and apoptosis of U251 cells with BAP1 knockdown.Results The results of bioinformatics showed that the expression of BAP1 in malignant glioma tissues was lower than that in normal brain tissues(GSE 4290:1 209±18.49 vs 1 476±53.90,GSE 90598:5.19±0.10 vs 5.65±0.21),and the differences were significant(t=5.115,2.267,all P<0.05).ROC curve showed that BAP1 could efficiently differentiate malignant glioma tissue from normal brain tissue(GSE4290:AUC=0.78,GSE90598:AUC=0.75,all P<0.05).The expression level of BAP1 in primary malignant glioma tissue was lower than that in normal brain tissue(0.27±0.04 vs 1.06±0.07),and the difference was significant(t=10.22,P<0.001).After down-regulating the expression of BAP1 in U251 cells,the proportion of S phase cells increased from 17.59%to 27.21%(siBAP1-1)and 25.79%(siBAP1-2),respectively,and the differences were significant(t=6.576,6.642,all P<0.01).However,the apoptosis levels decreased from 10.17%to 2.70%(siBAP-1)and 3.00%(siBAP-2),respectively,and the differences were significant(t=10.31,9.428,all P<0.01).Conclusion Histone H2A deubiquitinase BAP1 could exert the function of tumor suppressor genes by inhibiting rapid cell cycle progression and promoting apoptosis in malignant glioma,and could serve as a potential clinical diagnostic biomarker for malignant glioma.

OBJECTIVE To provide a reference for medical institutions in selecting and establishing a traditional Chinese medicine （TCM） clinical pharmaceutical care mode that suits their clinical characteristics. METHODS Combining clinical cases， this paper introduces the workflow and service content of the joint consultation mode between TCM physicians and TCM clinical pharmacists in our hospital and analyzes its effectiveness. RESULTS The workflow of the pharmaceutical care mode in our hospital involves six stages：assessing the patient’s medication status， consultation rounds and formulating medication regimen， bedside education， pharmaceutical monitoring， pharmacist rounds， and extended pharmaceutical care. The care content primarily includes thoroughly collecting clinical information and evaluating the patient’s medication regimen before the consultation. During the consultation， TCM clinical pharmacists and TCM physicians jointly developed a dosage regimen tailored to the patient’s individual conditions. After the consultation， bedside medication education was conducted to ensure the correct use of medications and a pharmaceutical monitoring plan was developed and implemented， during which the patient’s post-consultation condition changes were monitored and timely feedback to the TCM physicians for medication plan adjustments was provided， offering extended pharmaceutical care post-consultation， including medication consultation， pharmaceutical outpatient services， and joint clinics. Since its implementation， nearly 1 000 inpatients have been served annually， with a 100% medical order review rate for patients taking TCM decoction pieces. Individualized medication education reached 78.80%， and patient’s degree of satisfaction was 100%. The prescription compliance rate of TCM decoction pieces in the wards increased from 89.33% before the implementation of the joint consultation to 97.08% afterward. Additionally， the mode provided TCM-related consultations to over 1 000 patients annually and compiled and provided nearly a hundred pharmaceutical documents to healthcare personnel. CONCLUSIONS By establishing the joint consultation mode between TCM physicians and TCM clinical pharmacists and conducting TCM clinicalpharmaceutical care， the level of rational use of TCMdecoction pieces has been promoted， demonstrating the value of TCM clinical pharmacists.

Objective:To investigate the surgical situations and perioperative outcome of pancreaticoduodenectomy in Jiangsu Province and the influencing factors for postoperative 90-day mortality.Methods:The retrospective case-control study was conducted. The clinicopathological data of 2 886 patients who underwent pancreaticoduodenectomy in 21 large tertiary hospitals of Jiangsu Quality Control Center for Pancreatic Diseases, including The First Affiliated Hospital of Nanjing Medical University, from March 2021 to December 2022 were collected. There were 1 732 males and 1 154 females, aged 65(57,71)years. Under the framework of the Jiangsu Provincial Pancreatic Disease Quality Control Project, the Jiangsu Quality Control Center for Pancreatic Diseases adopted a multi-center registration research method to establish a provincial electronic database for pancrea-ticoduodenectomy. Observation indicators: (1) clinical characteristics; (2) intraoperative and post-operative conditions; (3) influencing factors for 90-day mortality after pancreaticoduodenectomy. Measurement data with skewed distribution were represented as M( Q1, Q3) or M(IQR), and comparison between groups was conducted using the Mann-Whitney U test. Count data were expressed as absolute numbers or constituent ratio, and comparison between groups was conducted using the chi-square test, continuity correction chi-square test and Fisher exact probability. Maximal Youden index method was used to determine the cutoff value of continuous variables. Univariate analysis was performed using the corresponding statistical methods based on data types. Multivariate analysis was performed using the Logistic multiple regression model. Results:(1) Clinical characteristics. Of the 2 886 patients who underwent pancreaticoduodenectomy, there were 1 175 and 1 711 cases in 2021 and 2022, respectively. Of the 21 hospitals, 8 hospitals had an average annual surgical volume of <36 cases for pancreaticoduodenectomy, 10 hospitals had an average annual surgical volume of 36-119 cases, and 3 hospitals had an average annual surgical volume of ≥120 cases. There were 2 584 cases performed pancreaticoduodenectomy in thirteen hospitals with an average annual surgical volume of ≥36 cases, accounting for 89.536%(2 584/2 886)of the total cases. There were 1 357 cases performed pancrea-ticoduodenectomy in three hospitals with an average annual surgical volume of ≥120 cases, accounting for 47.020%(1 357/2 886) of the total cases. (2) Intraoperative and postoperative conditions. Of the 2 886 patients, the surgical approach was open surgery in 2 397 cases, minimally invasive surgery in 488 cases, and it is unknown in 1 case. The pylorus was preserved in 871 cases, not preserved in 1 952 cases, and it is unknown in 63 cases. Combined organ resection was performed in 305 cases (including vascular resection in 209 cases), not combined organ resection in 2 579 cases, and it is unknown in 2 cases. The operation time of 2 885 patients was 290(115)minutes, the volume of intra-operative blood loss of 2 882 patients was 240(250)mL, and the intraoperative blood transfusion rate of 2 880 patients was 27.153%(782/2 880). Of the 2 886 patients, the invasive treatment rate was 11.342%(327/2 883), the unplanned Intensive Care Unit (ICU) treatment rate was 3.087%(89/2 883), the reoperation rate was 1.590%(45/2 830), the duration of postoperative hospital stay was 17(11)days, the hospitalization mortality rate was 0.798%(23/2 882), and the failure rate of rescue data in 2 083 cases with severe complications was 6.529%(19/291). There were 2 477 patients receiving postoperative 90-day follow-up, with the 90-day mortality of 2.705%(67/2477). The total incidence rate of complication in 2 886 patients was 58.997%(1 423/2 412). The incidence rate of severe complication was 13.970%(291/2 083). The comprehensive complication index was 8.7(22.6) in 2 078 patients. (3) Influencing factors for 90-day mortality after pancreaticoduodenectomy. Results of multivariate analysis showed that age ≥ 70 years, postoperative invasive treatment, and unplanned ICU treatment were independent risk factors for 90-day mortality after pancreaticoduodenectomy ( odds ratio=2.403, 2.609, 16.141, 95% confidence interval as 1.281-4.510, 1.298-5.244, 7.119-36.596, P<0.05). Average annual surgical volume ≥36 cases in the hospital was an independent protective factor for 90-day mortality after pancreaticoduodenectomy ( odds ratio=0.368, 95% confidence interval as 0.168-0.808, P<0.05). Conclusions:Pancreaticoduodenectomy in Jiangsu Province is highly con-centrated in some hospitals, with a high incidence of postoperative complications, and the risk of postoperative 90-day mortality is significant higher than that of hospitallization mortality. Age ≥ 70 years, postoperative invasive treatment, and unplanned ICU treatment are independent risk factors for 90-day motality after pancreaticoduodenectomy, and average annual surgical volume ≥36 cases in the hospital is an independent protective factor.

Objective:To retrospectively analyze the treatment status of tyrosine kinase inhibitors (TKI) in newly diagnosed patients with chronic myeloid leukemia (CML) in China.Methods:Data of chronic phase (CP) and accelerated phase (AP) CML patients diagnosed from January 2006 to December 2022 from 77 centers, ≥18 years old, and receiving initial imatinib, nilotinib, dasatinib or flumatinib-therapy within 6 months after diagnosis in China with complete data were retrospectively interrogated. The choice of initial TKI, current TKI medications, treatment switch and reasons, treatment responses and outcomes as well as the variables associated with them were analyzed.Results:6 893 patients in CP ( n=6 453, 93.6%) or AP ( n=440, 6.4%) receiving initial imatinib ( n=4 906, 71.2%), nilotinib ( n=1 157, 16.8%), dasatinib ( n=298, 4.3%) or flumatinib ( n=532, 7.2%) -therapy. With the median follow-up of 43 ( IQR 22-75) months, 1 581 (22.9%) patients switched TKI due to resistance ( n=1 055, 15.3%), intolerance ( n=248, 3.6%), pursuit of better efficacy ( n=168, 2.4%), economic or other reasons ( n=110, 1.6%). The frequency of switching TKI in AP patients was significantly-higher than that in CP patients (44.1% vs 21.5%, P<0.001), and more AP patients switched TKI due to resistance than CP patients (75.3% vs 66.1%, P=0.011). Multi-variable analyses showed that male, lower HGB concentration and ELTS intermediate/high-risk cohort were associated with lower cytogenetic and molecular responses rate and poor outcomes in CP patients; higher WBC count and initial the second-generation TKI treatment, the higher response rates; Ph + ACA at diagnosis, poor PFS. However, Sokal intermediate/high-risk cohort was only significantly-associated with lower CCyR and MMR rates and the poor PFS. Lower HGB concentration and larger spleen size were significantly-associated with the lower cytogenetic and molecular response rates in AP patients; initial the second-generation TKI treatment, the higher treatment response rates; lower PLT count, higher blasts and Ph + ACA, poorer TFS; Ph + ACA, poorer OS. Conclusion:At present, the vast majority of newly-diagnosed CML-CP or AP patients could benefit from TKI treatment in the long term with the good treatment responses and survival outcomes.

Objective:To explore the clinical efficacy and cardiovascular protective effect of sodium-glucose co-transporter 2 inhibitor(SGLT-2i)on patients with type 2 diabetic nephropathy(T2DN).Methods:A total of 376 T2DN patients admitted in our Department of Endocrinology and Department of Cardiology from January 2018 to December 2021 were selected.According to therapeutic program,they were divided into control group(n=177,re-ceived routine treatment program)and SGLT-2i group(n=199,received SGLT-2i based on routine treatment program),both groups were continuously treated for 1 year.Blood glucose,blood pressure,blood lipids,uric acid,body mass index,renal function-related indexes and the occurrence of major adverse cardiovascular events were compared between the two groups after 12 months,as well as the adverse drug reactions.Results:After 12-month treatment,compared with control group,there were significant reductions in levels of blood pressure,fasting blood glucose(FBG),glycosylated hemoglobin A1e(HbA1c),urinary albumin/creatinine ratio(UACR),creatinine(Cr),blood urea nitrogen(BUN),total cholesterol(TC),triglyceride(TG),low density lipoprotein cholesterol(LDL-C)and uric acid(UA),and significant rise in estimated glomerular filtration rate(eGFR),levels of high density lipoprotein cholesterol(HDL-C),albumin(Alb)and alanine aminotransferase(ALT)in SGLT-2i group(P＜0.05 or＜0.01).Incidence rates of acute myocardial infarction(1.51％vs.6.21％)and heart failure caused-readmission(2.51％vs.6.78％)in SGLT-2i group were significantly lower than those of control group,and inci-dence rate of urinary system infection(8.54％vs.1.69％)was significantly higher than that of control group(P＜0.05 all).Conclusion:SGLT-2i can not only effectively control blood glucose,but also reduce body weight and blood pressure,improve blood lipids,reduce uric acid,improve renal hyperfiltration,reduce urinary protein and possess unique cardiovascular benefits,but risk of urinary system infection calls for attention.

This study was aimed at comparing performance differences among three metagenomic sequencing platforms,MGISEQ-2000,Illumina NextSeq 2000,and Ion GeneStudio S5 Plus,to optimize the sequencing process for trace samples.The three sequencing platforms were used to perform high-throughput sequencing on DNA standards and simulated samples.Through analysis of the quality of raw data and microbial detection capabilities,systematic differences among platforms were compared.The sequencing results were optimized for trace samples by incorporation of exogenous nucleic acids during the li-brary preparation process.In terms of data output per batch and base quality,MGISEQ-2000 surpassed the other two plat-forms.Illumina NextSeq 2000 had the lowest proportion of duplicate reads,whereas Ion GeneStudio S5 Plus had the highest proportion,and significant differences were observed across platforms(P＜0.001).In sequencing uniformity,MGISEQ-2000 and Illumina NextSeq 2000 were superior to Ion GeneStudio S5 Plus.MGISEQ-2000 provided a substantial advantage in microbial detection capability(P＜0.001),but the advantage diminished with decreasing bacterial fluid concentration.Ion GeneStudio S5 Plus had the shortest duration for single-batch sequencing.Moreo-ver,for trace samples with DNA content ≤0.05 ng,the experi-mental group(with added exogenous nucleic acids)achieved a higher number of reads than the control group(without exogenous nucleic acids),with a 11.09±8.03 fold increase.In conclu-sion,the different sequencing platforms each had advantages and disadvantages,thus allowing researchers to choose the appro-priate platform according to specific needs.Furthermore,the addition of exogenous nucleic acids improved the microorganism detection efficiency,and provided better support for subsequent diagnosis and evaluation of results.

Objective:To explore the expression patterns of inhibitor of differentiation(ID)family in patients with chronic myeloid leukemia(CML)and analyze their clinical implications.Methods:Quantitative PCR and quantitative methylation-specific PCR were conducted to de-tect the transcript levels of ID2/ID3/ID4 and the methylation levels of ID4 in the bone marrow mononuclear cells of non-hematological ma-lignancies(acting as controls)and patients with CML treated at The Affiliated People's Hospital of Jiangsu University from January 2010 to December 2017.The clinical implications of ID family alterations were further analyzed.Results:ID2 and ID3 expression was significantly up regulated(P<0.001 and P<0.05,respectively),whereas ID4 expression was markedly down regulated in patients with CML(P<0.01).The re-ceiver operating characteristic curve demonstrated that the ID2 transcript level is a potential biomarker for distinguishing CML from controls(AUC=0.895,P<0.001).The frequency of ID4 promoter methylation in patients with CML was drastically higher than that in the controls(P=0.001).Moreover,ID4 methylation was negatively correlated with ID4 expression in patients with CML(r=-0.424,P=0.002).Clinically,CML with high ID2 expression occurred more frequently in males(P=0.040).Patients with low ID4 expression or high ID4 methylation showed a markedly higher frequency of an accelerated phase/blast crisis(P=0.003 and P<0.001,respectively).In addition,patients with CML in an accelerated phase/blast crisis exhibited markedly lower ID4 expression and higher ID4 methylation levels than those in the chronic phase(both P<0.001).Furthermore,univariate and multiple Logistic regression analyses revealed that the ID4 methylation level was an inde-pendent risk factor for CML progression(P=0.007).Conclusions:The ID family was differentially expressed in patients with CML;specifically,ID2 and ID3 expression was significantly increased,whereas ID4 expression was markedly decreased and correlated with ID4 promoter hy-permethylation.Hence,ID4 expression and methylation are confirmed to be associated with CML progression,and ID4 methylation could be an independent risk factor for CML progression.

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 explore the impact of intradialytic hypotension (IDH) on brain component volume, as well as its relationship with depression and cognitive function changes in maintenance hemodialysis patients.Method:It was a cross-sectional observational study. Clinical data of 119 patients under maintenance hemodialysis in Peking Union Medical College Hospital from July 2013 to July 2014 were collected, retrospectively. Patients were divided into IDH group and non-IDH group. 3.0T Magnetic resonance imaging examination of the head for all patients was completed and the results of volume analysis of each component of the brain were extracted. Cognitive function was assessed by the Chinese version of the simplified mental state examination scale (C-MMSE) and the Chinese version of the Montreal cognitive assessment scale (C-MoCA). Depressive status was assessed by the Hamilton depression scale 17 (HAMD_17) and living ability was assessed by the Alzheimer's disease collaborative study-daily living ability assessment questionnaire. In addition, the Philadelphia word learning test was used to measure memory, the Boston naming test to measure language, the connection test A and B to measure executive ability, and the Stroup test C to measure attention. The differences in brain component volume, cognitive function, emotion, and life ability between two groups of patients were compared, and the correlation between IDH and brain component volume was explored by regression analysis.Result:A total of 119 patients were included in this study, of whom 22 (18.5%) had hypotension during dialysis. The volumes of amygdala, cuneiform lobe, and posterior cingulate gyrus in IDH group were significantly smaller than those in the non-hypotension group [ (1.6±0.2) mm 3vs. (1.7±0.2) mm 3, t=2.674, P=0.009; (6.9±0.8) mm 3vs. (7.4±1.0) mm 3, t=2.187, P=0.031; (6.9±0.8) mm 3vs. (7.4±0.9) mm 3, t=2.252, P=0.024]. The differences of gray matter, white matter volume between the two groups showed a similar trend but did not reach statistical significance. And lacunar infarction and cerebral microbleeds were more common in IDH group. The daily living ability scores of the two groups were similar (65.51±11.52 vs. 65.71±11.53, Z=-0.456, P=0.648). The proportion of patients with cognitive abnormalities was higher in the IDH group, without statistical significance. The proportion of depression was similar. Univariate linear regression analysis showed that IDH was significantly negatively correlated with the volume of amygdala, cuneiform cortex, and posterior cingulate gyrus, which control emotions in the brain ( B=-0.117, 95% CI -0.203--0.030, P=0.009; B=-0.484, 95% CI -0.923--0.046, P=0.031; B=-0.485, 95% CI -0.911--0.058, P=0.026). After multivariate adjustment, decreased amygdala volume was still correlated with IDH ( B=-0.111, 95% CI -0.198--0.025, P=0.026). Conclusion:Recurrent IDH may lead to atrophy of various brain components, which may be one of the reasons for cognitive and emotional changes in maintenance hemodialysis patients.

Background: Triglyceride glucose (TyG) and TyG-body mass index (TyG-BMI) are reliable surrogate indices of insulin resistance and used for risk stratification and outcome prediction in patients with atherosclerotic cardiovascular disease (ASCVD). Here, we inserted estimated average glucose (eAG) into the TyG (TyAG) and TyG-BMI (TyAG-BMI) as derived parameters and explored their clinical significance in cardiovascular risk prediction. Methods: This was a population-based cohort study of 9,944 Chinese patients with ASCVD. The baseline admission fasting glucose and A1C-derived eAG values were recorded. Cardiovascular events (CVEs) that occurred during an average of 38.5 months of follow-up were recorded. We stratified the patients into four groups by quartiles of the parameters. Baseline data and outcomes were analyzed. Results: Distribution of the TyAG and TyAG-BMI indices shifted slightly toward higher values (the right side) compared with TyG and TyG-BMI, respectively. The baseline levels of cardiovascular risk factors and coronary severity increased with quartile of TyG, TyAG, TyG-BMI, and TyAG-BMI (all P<0.001). The multivariate-adjusted hazard ratios for CVEs when the highest and lowest quartiles were compared from low to high were 1.02 (95% confidence interval [CI], 0.77 to 1.36; TyG), 1.29 (95% CI, 0.97 to 1.73; TyAG), 1.59 (95% CI, 1.01 to 2.58; TyG-BMI), and 1.91 (95% CI, 1.16 to 3.15; TyAG-BMI). The latter two showed statistical significance. Conclusion This study suggests that TyAG and TyAG-BMI exhibit more information than TyG and TyG-BMI in disease progression among patients with ASCVD. The TyAG-BMI index provided better predictive performance for CVEs than other parameters.
