Objective:To determine the incidence of adrenal incidentalomas(AIs) in patients with diabetes mellitus and the metabolism profiles.Methods:A total of 615 hospitalized patients with diabetes mellitus in the Department of Endocrinology and Metabolism of Peking University People′s Hospital from March 2020 to May 2021 were retrospectively included in this study. AIs were screened by unenhanced chest computed tomography(CT) retrospectively and subsequently confirmed by multiplanar reconstruction. Participants′ physical indicators, metabolic profiles, and adrenal function parameters were collected. Unpaired t test, Mann-Whitney U test, and Chi-Square test were adopted to compare the metabolism profiles between diabetes mellitus patients with or without AIs. Regression models were used to estimate the correlations between AIs and the metabolism profiles such as blood glucose, blood lipids, blood pressure, and the adrenal function parameters.Results:Twenty-seven out of 615 participants were detected with AIs(4.4%). Patients with AIs had higher body mass index, waist circumference, and hip circumference than patients without AIs [(29.4±5.1)kg/m 2vs(26.8±3.8)kg/m 2,P=0.018; (102.3±11.7)cm vs(95.8±10.3)cm, P=0.002; (107.3±10.1)cm vs(101.4±7.6)cm, P=0.008]. The levels of serum uric acid and urinary albumin/creatinine ratio were also significantly increased in patients with AIs [(409.6±118.1)μmol/L vs(357.4±100.6)μmol/L, P=0.009; 21.25(7.49, 180.24)mg/g vs 8.60(4.71, 34.56)mg/g, P=0.010]. Besides, individuals with AIs were also associated with a higher risk of co-existing hypertension( P=0.045). Conclusion:The incidence of AIs in patients with diabetes is 4.4%. The presence of AIs in patients with diabetes may associated with increased risk of obesity and hypertension.

OBJECTIVE To observe the short-term efficacy and safety of venetoclax combined with homoharringtonine and cytarabine in the treatment of acute myeloid leukemia （AML）. METHODS The data of 40 newly diagnosed AML patients admitted to our hospital from October 2022 to November 2023 were retrospectively collected and divided into observation group and control group according to treatment plan， with 20 cases in each group. The patients in the control group were given Daunorubicin hydrochloride for injection+Cytarabine for injection， and the patients in the observation group were given Venetoclax tablets+ Homoharringtonine injection+Cytarabine for injection. The patients in both groups were given relevant medicine， with 28 days as one cycle. The short-term efficacy， negative rate of minimal residual disease （MRD）， duration of granulocyte deficiency， duration of platelet （PLT） ＜20×109 L－1， transfusion volume of suspended red blood cells and platelet， and the occurrence of adverse drug reactions were evaluated in both groups after 1 cycle of induction chemotherapy. RESULTS The complete remission or complete remission with incomplete hematologic recovery （CR/CRi） rate in the observation group was significantly higher than control group （P＜0.05）， and the negative rate of MRD in the observation group was also significantly higher than control group （P＜0.05）. However， in low-， medium- and high-risk patients， there was no statistical significance in CR/CRi rates between the two groups （P＞0.05）. There were no significant differences in the duration of agranulocytosis， the duration of PLT ＜20×109 L－1， the amount of suspended red blood cell transfusion， the amount of platelet transfusion， the incidence of hematologic toxicity and the incidence of non-hematologic toxicity between 2 groups （P＞0.05）. CONCLUSIONS Venetoclax combined with homoharringtonine and cytarabine show good short-term efficacy and safety in the treatment of AML.

Background::Although overnight fasting is recommended prior to endoscopic retrograde cholangiopancreatography (ERCP), the benefits and safety of high-carbohydrate fluid diet (CFD) intake 2 h before ERCP remain unclear. This study aimed to analyze whether high-CFD intake 2 h before ERCP can be safe and accelerate patients’ recovery.Methods::This prospective, multicenter, randomized controlled trial involved 15 tertiary ERCP centers. A total of 1330 patients were randomized into CFD group ( n = 665) and fasting group ( n = 665). The CFD group received 400 mL of maltodextrin orally 2 h before ERCP, while the control group abstained from food/water overnight (>6 h) before ERCP. All ERCP procedures were performed using deep sedation with intravenous propofol. The investigators were blinded but not the patients. The primary outcomes included postoperative fatigue and abdominal pain score, and the secondary outcomes included complications and changes in metabolic indicators. The outcomes were analyzed according to a modified intention-to-treat principle. Results::The post-ERCP fatigue scores were significantly lower at 4 h (4.1 ± 2.6 vs. 4.8 ± 2.8, t = 4.23, P <0.001) and 20 h (2.4 ± 2.1 vs. 3.4 ± 2.4, t= 7.94, P <0.001) in the CFD group, with least-squares mean differences of 0.48 (95% confidence interval [CI]: 0.26–0.71, P <0.001) and 0.76 (95% CI: 0.57–0.95, P <0.001), respectively. The 4-h pain scores (2.1 ± 1.7 vs. 2.2 ± 1.7, t = 2.60, P = 0.009, with a least-squares mean difference of 0.21 [95% CI: 0.05–0.37]) and positive urine ketone levels (7.7% [39/509] vs. 15.4% [82/533], χ2 = 15.13, P <0.001) were lower in the CFD group. The CFD group had significantly less cholangitis (2.1% [13/634] vs. 4.0% [26/658], χ2 = 3.99, P = 0.046) but not pancreatitis (5.5% [35/634] vs. 6.5% [43/658], χ2 = 0.59, P = 0.444). Subgroup analysis revealed that CFD reduced the incidence of complications in patients with native papilla (odds ratio [OR]: 0.61, 95% CI: 0.39–0.95, P = 0.028) in the multivariable models. Conclusion::Ingesting 400 mL of CFD 2 h before ERCP is safe, with a reduction in post-ERCP fatigue, abdominal pain, and cholangitis during recovery.Trail Registration::ClinicalTrials.gov, No. NCT03075280.

Bluetongue virus is an arbovirus that seriously harms ruminants such as sheep,this study aims to investigate the molecular mechanism of bluetongue virus infection and host cell interferon antiviral immune response.The study was conducted to characterize the mRNA expression of inter-feron pathway genes by real-time fluorescence quantitative PCR,as well as Western blot analysis of MDA5,TRAF3,RIG-Ⅰ,and TBK1 protein expression in BHK-21 cells induced by BTV with a multiplicity of infections(MOI)of 1 for 18,24,and 36 h.The results showed that the most pro-nounced changes in the expression of interferon signaling pathway genes were observed at 24 h of induction,the gene mRNA expression levels of the IFN-α,IFN-β,RIG-Ⅰ,TBK1,MDA5,VISA,and TRAF3 genes were upregulated.However,the mRNA expression levels of IKKε and TRAF6 genes were downregulated.At the protein level,MDA5 and TBK1 proteins were upregulated while RIG-1 and TRAF3 proteins were downregulated,which showed that BTV infection induces a typeⅠ interferon immune response in BHK-21 cells.This study lays the foundation for further exploring the antiviral immunity mechanism of IFN-Ⅰ signaling pathway regulatory genes in host cells infected with BTV infection.

Objective To investigate the curative effect of interventional therapy on postoperative multiple metastases of breast cancer.Methods A total of 15 patients with multiple metastases after breast cancer surgery were treated with interventional therapy.After comprehensive evaluation,all patients were treated with chemoembolization.The therapeutic regimen was docetaxel loaded on drug-eluting bead(DEB)combined with carboplatin,once in 1 d for 21 d,2 times in total,and then the regimen was changed to docetaxel and carboplatin combined with ordinary embolization microspheres,once in 1 d for 21 d,4 times in total.CT/MRI was performed on every 2 cycles and 1,3,and 6 months after interventional therapy to evaluate its efficacy and record adverse reactions.Results The overall remission rate(ORR)at 3 months after treatment was 75％,and the disease control rate(DCR)was 91.7％.The ORR and DCR at 6 months after treatment were 50％and 83.3％,respectively.Most of the common adverse reactions were below grade Ⅲ.Conclusion Interventional therapy for multiple metastases of breast cancer after operation has a definite short-term effect,with little adverse reactions.It is worthy of further promotion in the comprehensive treatment of postoperative metastases of breast cancer.

Objective To investigate the prognostic evaluation value of the HALP score composed of hemoglobin,albumin,lymphocytes and platelets before chemotherapy in the patients with diffuse large B-cell lymphoma(DLBCL).Methods The clinical data and laboratory indicators before chemotherapy in the pa-tients with DLBCL newly diagnosed in this hospital from January 2015 to October 2022 were retrospectively analyzed.The optimal cut-off value of HALP was calculated by X-tile software.The patients were grouped ac-cording to the optimal cutoff value,the Chi-square test was used to analyze the difference in the constituent ra-tio of clinical characteristics among different HALP score groups,the survival curves of the progression-free survival(PFS)time and overall survival(OS)time among the groups with different scores were drawn by u-sing the Kaplan-Meier method,the Cox univariate and multivariate analysis regression model was adopted to analyze the prognostic influencing factors in DLBCL patients,and the predictive ability of HALP score for PFS time and OS time in DLBCL patients was evaluated by using the receiver operating characteristic(ROC)curve.Results A total of 132 patients with DLBCL were included,the optimal cutoff value of HALP score was 21.23 points.There were 54 cases in the low HALP score group and 78 cases in the high HALP score group.The low HALP score group was correlated with the later clinical stage,higher IPI and NCCN-IPI scores,higher LDH level and lower overall response rate(ORR)(P＜0.05).Compared to the high HALP score group,the PFS time and OS time in the low HALP score group were shorter(P＜0.05).The Cox uni-variate and multivariate regression model analysis results indicated that the HALP score≤21.23 points was an independent risk factor affecting the PFS time(HR=1.811,P=0.031).The ROC curve results suggested that the combination of HALP score combined with IPI score or NCCN-IPI score had higher predictive value for PFS time and OS time in DLBCL patients compared to use IPI or NCCN-IPI alone.Conclusion The HALP score is correlated with the prognosis of DLBCL patients,and could early identify the high-risk DLBCL patients with poor prognosis.The HALP score,IPI score and NCCN-IPI score combined evaluation has higher predictive value.
