Objective:To investigate the effects of ubiquitin-specific protease (USP) 7/47 inhibitor (Cat. No. 1247825-37-1) on the proliferation and apoptosis of acute myeloid leukemia (AML) cells with or without internal tandem duplications of the Flt3 gene (Flt3-ITD). Methods:ATP assay was used to detect the effects of 1247825-37-1 on the cell viability of two AML cell lines (MOLM13 and MV4-11) harboring Flt3-ITD mutation and one AML cell line (THP-1) without Flt3-ITD mutation as well as the primary Flt3-ITD-mutant and non-mutant AML cells from patient samples. Flow cytometry was used to detect the apoptosis of AML cell lines treated by different concentrations of 1247825-37-1.Results:Compared with the control group, 1247825-37-1 was able to significantly inhibit the proliferation of MOLM13, MV4-11 and THP-1 cells ( P<0.000 1). Besides, the cell viability of primary AML cells was also inhibited by 1247825-37-1, and a stronger inhibitory effect on non-mutant AML cells was observed. The USP7/USP47 inhibitor 1247825-37-1 could inhibit the proliferation of AML cells in a dose-dependent manner and a low dose (2 or 4 μmol/L) of 1247825-37-1 would be effective. Moreover, 1247825-37-1 was also able to efficiently induce the apoptosis of above AML cell lines in a dose-dependent manner. Conclusions:The USP7/USP47 inhibitor 1247825-37-1 significantly inhibits the proliferation of AML cells with or without Flt3-ITD mutation.

Objective To investigate the clinical efficacy of mitral valve repair technique in the treatment of rheumatic mitral valve lesions. Methods The clinical data of patients diagnosed with rheumatic mitral valve lesions and undergoing mitral valve repair under extracorporeal circulation in our department from 2021 to 2022 were retrospectively analyzed. Results A total of 100 patients were collected, including 78 females and 22 males with an average age of 52 years. There were no secondary open heart or death in the whole group. Extracorporeal circulation time was 136.3±33.1 min, aortic cross-clamping time was 107.6±27.5 min, ventilator use time was 12.9±5.9 h, ICU stay was 2.6±1.4 d, and vasoactive medication use was 823.4±584.4 mg. Before and after the surgery, there were statistical differences in the left ventricular end diastolic diameter, left atrial end systolic diameter, effective mitral valve orifice area, shortening rate of left ventricular short axis, mitral E-peak blood flow velocity, mean mitral transvalvular pressure difference, mitral pressure half-time, and cardiac function graded by New York Heart Association (P＜0.05). While there was no statistical difference in left ventricular ejection fraction or left ventricular end-diastolic volume (P>0.05). Conclusion Overall repair of rheumatic mitral valve lesions can significantly improve the cardiac function and hemodynamics of the patients, and is a good choice for patients with rheumatic mitral valve lesions.

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 systematically evaluate the clinical efficacy of fire needle therapy and conventional western medicine in the treatment of patients with acute herpes zoster.Methods:Randomized controlled trials (RCTs) of fire needle therapy in the treatment of acute herpes zoster were retrieved from China National Knowledge Internet (CNKI), Wanfang, Database of Chinese Sci Tech Periodicals (VIP Database), China Biomedical Literature Database (CBM), Medline, Embase, and Cochrane Library from the establishment of the databases to May 30, 2022. According to the inclusion and exclusion criteria, the included literature was screened, and Review Manager 5.3 was used for system evaluation and meta-analysis.Results:7 articles were included for analysis after screening, involving 452 patients. There were 226 cases in the treatment group and 226 cases in the control group. The results of meta-analysis showed that fire needle therapy was superior to conventional western medicine in the total effective rate [ RR=0.36, 95% CI (0.20, 0.65), P=0.000 7], lower incidence of PHN [ RR=0.25, 95% CI (0.09, 0.72), P=0.01], lower VAS score [ MD=-1.19, 95% CI (-2.14, -0.24), P=0.01], and shorter scab forming time [ MD=-2.03, 95% CI (-2.42, -1.64), P<0.001]. Conclusion:The curative effect of fire needle therapy is more prominent than that of conventional western medicine in the treatment of acute herpes zoster.

Objective:To analyze the influencing factors of type 2 diabetes patients with mild cognitive impairment by Logistic regression and decision tree analysis, so as to provide reference for the prevention of these patients.Methods:The cross sectional investigation and convenience sampling method was used for the observational study, patients with type 2 diabetes hospitalized in the Endocrinology Department of the Drum Tower Hospital Affiliated of Nanjing University Medical School from April 2019 to August 2022 were selected as the objects, they were divided into the cognitive normal group and the mild cognitive impairment group, single factor analysis and Lasso analysis were used to screen variables. Logistic regression and decision tree analysis of diabetes with mild cognitive impairment were established and evaluated respectively.Results:Logistic regression analysis and decision tree analysis both showed that age, years of education, and insulin sensitivity index were effective early warning indicators of mild cognitive impairment with type 2 diabetes ( Z = - 9.39, 12.21, - 4.62, all P<0.05), and the decision tree model analysis showed that the number of years of education had the highest correlation with mild cognitive impairment. The different influencing factors of the two models were peripheral neuropathy, abnormal bone metabolism, and lower limb macroangiopathy. The specificity (62.7%) of the Logistic regression model was lower than that of the decision tree model (81.6%), and the sensitivity (77.3%) was higher than that of the decision tree model (54.9%). The AUC of the logistic regression model was 0.763 (95% CI 0.737-0.790), and the AUC of the decision tree model was 0.743 (95% CI 0.715-0.771). There was no difference in the predictive performance of the two models ( Z = 1.05, P = 0.295). Conclusions:The prediction ability of Logistic regression analysis model is similar to that of decision tree model. The Logistic regression analysis model can be used to screen out meaningful main effect early warning indicators, and further analysis of the correlation between indicators and research outcomes, as well as the interaction between various research factors, using a decision tree model, providing a reference for the prevention and control of diabetes patients with mild cognitive impairment.

The incidence of FLT3-internal tandem duplication (ITD) mutation in acute myeloid leukemia (AML) is approximately 20%-30% and FLT3-ITD mutation generally indicates a poor prognosis. Although FLT3 inhibitors have greatly improved the efficacy of AML patients with this type of AML, relapse and drug-resistance increasingly become prominent. ITD mutations lead to dimerization and continuous self-activation of FLT3 in the absence of ligands, and cause non-ligand-dependent phosphorylation. Different characteristics of ITD, including allele ratio, length, insertion site, wild-type mutation content and co-mutated genes, could affect the prognosis of patients. The underlying mechanism of these factors has an important guiding significance for clinical prognosis, drug application and treatment strategy.

Objective:To investigate the clinical features, treatments and prognoses of children with antibody-mediated central nervous system (CNS) autoimmune diseases.Methods:Two hundred and seven children with antibody-mediated CNS autoimmune diseases confirmed by anti-neuronal antibody detection in blood and/or cerebrospinal fluid in Department of Neurology, Children's Hospital of Hunan Province from June 2014 to May 2022 were enrolled. Their clinical features, laboratory and imaging data, treatment regimens and prognoses were retrospectively analyzed.Results:Of the 207 children, 117 were positive for anti- N-methyl- D-aspartate receptor (NMDAR) antibodies, 63 for anti-myelin oligodendrocyte glycoprotein (MOG) antibodies, 32 for anti-glial fibrillary acidic protein (GFAP) antibodies, 6 for anti-contactin-associated protein-like 2 (CNTNAP2) antibodies, 3 for anti-aquaporin 4 (AQP4) antibodies, 2 for anti-gamma-aminobutyric acid type B receptor (GABABR) antibodies, and 1 for anti-anti-leucine-rich glioma-inactivated 1 (LGI1) antibodies. Acute disseminated encephalomyelitis (ADEM) was the most common clinical phenotype among the children, followed by optic neuritis (ON). Behavioral abnormalities, seizures, and involuntary movements were the most common clinical presentations of anti-NMDAR encephalitis for these children, while fever, headache, and disturbance of consciousness or vision were the most common symptoms for children with MOG antibody disease or autoimmune GFAP astrocytopathy. The coexistence of multiple anti-neural antibodies was detected in 17 patients, among which 10 had coexistent anti-NMDAR and anti-MOG antibodies (including 1 with anti-GFAP antibody), 3 had coexistent anti-NMDAR and anti-GFAP antibodies, 3 had coexistent anti-MOG and anti-GFAP antibodies, 2 had coexistent anti-NMDAR and anti-CASPR2 antibodies, and 1 had coexistent anti-GABABR and anti-CASPR2 antibodies. In our cohort, of the 202 children examined for cerebrospinal fluid, 154 had cerebrospinal fluid leukocytosis and 27 had elevated protein. Of the 203 children had electroencephalography, 179 was abnormal; abnormal EEG was mainly manifested as focal or global slow waves, and epileptic discharge in some children; 205 patients received immunotherapy. All survivors were followed up for at least 6 months; 164 recovered completely, 40 had varied sequelae, and 3 died; 28 had one or more relapses. Conclusion:Antibody-mediated CNS autoimmune diseases occur in children at all ages; most such pediatric patients have good response to immunotherapy, enjoying low mortality rate; however, some survivors have relapsing risk.
