OBJECTIVE: To analyze the Epstein-Barr virus (EBV) load in different lymphocyte subsets, as well as clinical characteristics and outcomes in patients with hematologic malignancies experiencing EBV reactivation. METHODS: Peripheral blood samples from patients were collected. B, T, and NK cells were isolated sorting with magnetic beads by flow cytometry. The EBV load in each subset was quantitated by real-time quantitative polymerase chain reaction (RT-qPCR). Clinical data were colleted from electronic medical records. Survival status was followed up through outpatient visits and telephone calls. Statistical analyses were performed using SPSS 25.0. RESULTS: A total of 39 patients with hematologic malignancies were included, among whom 35 patients had undergone allogeneic hematopoietic stem cell transplantation (allo-HSCT). The median time to EBV reactivation was 4.8 months (range: 1.7-57.1 months) after allo-HSCT. EBV was detected in B, T, and NK cells in 20 patients, in B and T cells in 11 patients, and only in B cells in 4 patients. In the 35 patients, the median EBV load in B cells was 2.19×10⁴ copies/ml, significantly higher than that in T cells (4.00×10³ copies/ml, P <0.01) and NK cells (2.85×10² copies/ml, P <0.01). Rituximab (RTX) was administered for 32 patients, resulting in EBV negativity in 32 patients with a median time of 8 days (range: 2-39 days). Post-treatment analysis of 13 patients showed EBV were all negative in B, T, and NK cells. In the four non-transplant patients, the median time to EBV reactivation was 35 days (range: 1-328 days) after diagnosis of the primary disease. EBV was detected in one or two subsets of B, T, or NK cells, but not simultaneously in all three subsets. These patients received a combination chemotherapy targeting at the primary disease, with 3 patients achieving EBV negativity, and the median time to be negative was 40 days (range: 13-75 days). CONCLUSION In hematologic malignancy patients after allo-HSCT, EBV reactivation commonly involves B, T, and NK cells, with a significantly higher viral load in B cells compared to T and NK cells. Rituximab is effective for EBV clearance. In non-transplant patients, EBV reactivation is restricted to one or two lymphocyte subsets, and clearance is slower, highlighting the need for prompt anti-tumor therapy.

OBJECTIVE: This study aimed to explore the association between body mass index (BMI) and mortality based on the 10-year population-based multicenter prospective study. METHODS: A general population-based multicenter prospective study was conducted at four sites in rural China between 2013 and 2023. Multivariate Cox proportional hazards models and restricted cubic spline analyses were used to assess the association between BMI and mortality. Stratified analyses were performed based on the individual characteristics of the participants. RESULTS: Overall, 19,107 participants with a sum of 163,095 person-years were included and 1,910 participants died. The underweight (< 18.5 kg/m ²) presented an increase in all-cause mortality (adjusted hazards ratio [ aHR] = 2.00, 95% confidence interval [ CI]: 1.66-2.41), while overweight (≥ 24.0 to < 28.0 kg/m ²) and obesity (≥ 28.0 kg/m ²) presented a decrease with an aHR of 0.61 (95% CI: 0.52-0.73) and 0.51 (95% CI: 0.37-0.70), respectively. Overweight ( aHR = 0.76, 95% CI: 0.67-0.86) and mild obesity ( aHR = 0.72, 95% CI: 0.59-0.87) had a positive impact on mortality in people older than 60 years. All-cause mortality decreased rapidly until reaching a BMI of 25.7 kg/m ² ( aHR = 0.95, 95% CI: 0.92-0.98) and increased slightly above that value, indicating a U-shaped association. The beneficial impact of being overweight on mortality was robust in most subgroups and sensitivity analyses. CONCLUSION This study provides additional evidence that overweight and mild obesity may be inversely related to the risk of death in individuals older than 60 years. Therefore, it is essential to consider age differences when formulating health and weight management strategies.

Objective:To explore the application value and damage control of minimally inva-sive techniques in the treatment of acute incarcerated inguinal hernias in the elderly.Methods:In this study,62 elderly patients with acute incarcerated inguinal hernias admitted to the department of emergency surgery at the First Affiliated Hospital of Anhui Medical University from June 2018 to June 2023 were selected as the research subjects.After obtaining informed consent from the pa-tient's family for both treatment modalities,they were randomly divided into open surgery group and laparoscopic surgery group.Differences in clinical efficacy,perioperative indicators,post-operative complications,and prognostic follow-up of the two groups of patients were observed.Seven cases of elderly patients aged above 80 had many underlying diseases and poor tolerance during surgery.After treatment of lesions in the hernia contents,only damage control surgery for hernia sac high ligation was performed.Results:In comparison to patients treated with laparo-scopic surgery,there were statistically significant differences(P＜0.05)in the open surgery group in clinical efficacy(efficacy,ineffectiveness,and overall effectiveness),perioperative indicators(length of stay,recovery time of digestive tract function,and VAS pain score),post-operative complica-tions,and prognostic follow-up(local mass,chronic pain,and ratio of second-stage hernia sur-gery).Seven patients treated according to injury control strategies all recovered and discharged from hospital after surgery.Conclusion:Emergency laparoscopic surgery for detecting incarcer-ated inguinal hernias in the elderly is safe and feasible.At the same time,it is essential to correctly assess the patient's vital signs during surgery.If necessary,surgery should be simplified to provide opportunities for follow-up treatment.

Objective:To explore the effects of internet-based group cognitive-behavioral therapy(IGCBT)on the depressive and anxiety symptoms in patients with major depressive disorder(MDD).Methods:Eighty pa-tients with MDD were recruited and randomly divided into IGCBT combined drug therapy group and control group with drug therapy.Blind assessments were performed using the Hamilton Depression Scale(HAMD)and Hamilton Anxiety Scale(HAMA)three times at baseline,4 weeks after treatment and 8 weeks after treatment,respectively.Results:The effective rates of HAMD and HAMA at the end of the 4th and 8th week,and the effective rates of HAMA at the end of the 8th week were higher in the combined treatment group than those in the control group(Ps＜0.05).The total scores of HAMD and HAMA in the combined treatment group and the control group were lower at the end of the 4th and 8th week than those at baseline(Ps＜0.001).The total scores of HAMD and HAMA were lower in the combined treatment group than those in the control group at the baseline,4 weeks and 8 weeks after treatment(Ps＜0.01).Conclusion:It suggests that intemet-based group cognitive-behavioral therapy combined with antidepressant medication has a better effect on relieving depressive and anxiety symptoms in patients with ma-jor depressive disorder than drug therapy alone,and especially has a better effect on improving anxiety symptom.

AIM:To investigate the effects of sodium selenite(SS)on viability,migration and angiogenesis of human non-small-cell lung cancer(NSCLC)H520 and A549 cells.METHODS:The H520 cells,A549 cells,and hu-man umbilical vein endothelial cells(HUVEC)were divided into control group(0 μmol/L SS),low dose group(5 μmol/L SS),middle dose group(10 μmol/L SS),and high dose group(20 μmol/L SS).Cell viability was assessed using the CCK-8 assay,and the half-maximal inhibitory concentration(IC50)was calculated.Cell migration and invasion abilities were determined through wound healing and Transwell assays.The regulatory effects of SS on angiogenesis,vasculogenic mimicry and"mosaic"vascular formation between HUVEC and NSCLC cells were detected using vessel forming assays.The expression of vascular endothelial growth factor(VEGF)in the supernatant of lung cancer cells in each group was de-tected using chemiluminescence.RT-qPCR was used to assess the mRNA expression of VEGF,vascular endothelial growth factor receptor 2(VEGFR2)and angiotensin II(Ang II).Western blot was used to examine the protein levels of VEGF,p-PI3K,and p-Akt in H520 and A549 cells.RESULTS:The IC50 values of SS to HUVEC,A549 cells and H520 cells for 48 h were 6.762,9.003 and 7.356 μmol/L,respectively.Compared with control group,the wound healing rate was significantly decreased in each group treated with SS for 48 h(P<0.01).In HUVEC,the number of migrating cells in middle dose and high dose groups decreased(P<0.01),whereas in lung cancer cells,the number of migrating cells in each group decreased after SS treatment(P<0.01).The mRNA expression levels of VEGF,VEGFR2 and Ang II were lower in high-dose SS group than those in control group(P<0.05 or P<0.01).In H520 cells,compared with control group,the protein levels of VEGF,p-PI3K and p-Akt in SS treatment groups were significantly decreased(P<0.05 or P<0.01).CONCLUSION:Sodium selenite inhibits the viability and migration of HUVEC,H520 cells and A549 cells,and inhibits the formation of vasculogenic mimicry and mosaic vessels in NSCLC cells.This mechanism may be related to the inhibition of PI3K-Akt signaling pathway activation and regulation of VEGF.

Objective To investigate the effect of the loss of myeloid-derived growth factor(Mydgf)on the transformation of cardiac fibroblasts into myofibroblasts after myocardial infarction(MI).Methods Two adult mouse groups,including a wild-type(WT)group and another group with Mydgf knockout(Mydgf-KO),were examined in the study.The mice in these two groups were tested for their cardiac function by measuring left ventricular ejection fraction(LVEF)and left ventricular fractional shortening(LVFS)(n=10).Quantitative real-time PCR(qRT-PCR)(n=3)was performed to determine the mRNA expression levels of myofibroblast markers,including α-smooth muscle actin(α-SMA),periostin(postn),type Ⅷ collagen(col8al),and connective tissue growth factor(ctgf).Western blot(n=3)was performed to verify the protein expression levels of α-SMA.MI modeling was performed on the WT and the Mydgf-KO mice.Postoperative LVEF and LVFS(n=10)were then measured.The hearts were harvested and Masson staining was performed to determine the infarcted area(n=10).The heart samples of Mydgf-KO and WT mice were collected at d 7 and d 14 after MI,respectively,to verify the expression of myofibroblast markers(n=3).Results Compared with WT mice,LVEF and LVFS in adult Mydgf-KO mice showed no significant changes(all P＞0.05).However,the mRNA levels of α-SMA and postn were upregulated,and α-SMA protein expression was also increased(all P＜0.05).After MI,compared with WT mice,LVEF and LVFS in Mydgf-KO mice decreased,and the infarcted area increased significantly(all P＜0.05).Furthermore,mRNA levels of α-SMA,col8al,postn,and ctgf were increased in Mydgf-KO mice.In addition,the α-SMA protein expression level was upregulated and α-SMA-positive fibroblasts were increased(P＜0.05).Conclusion Mydgf deletion promotes the transformation of cardiac fibroblasts into myofibroblasts and aggravates myocardial fibrosis after MI.

Objective By using high-resolution magnetic resonance angiography to display the vascular wall imaging so as to evaluate the relationship between plaque characteristics and postoperative in-stent restenosis(ISR)in patients with middle cerebral artery stenosis.Methods A total of 66 patients with symptomatic atherosclerotic middle cerebral artery stenosis,who were admitted to the Affiliated Hospital of Chengde Medical College of China from January 2019 to March 2023,were enrolled in this study.Before stent implantation,all the 66 patients completed high-resolution magnetic resonance angiography.According to the postoperative imaging follow-up results,the patients were divided into ISR group and non-ISR group.The preoperative plaque characteristics,which were assessed by high-resolution magnetic resonance imaging,were compared between the two groups.Results ISR group had 14 patients and non-ISR group had 52 patients.Most of the plaques were located in the inferior lateral wall(37.8％)and the ventral lateral wall(28.7％),in which no statistically significant difference existed between the two groups(P＞0.05).Compared with non-ISR group,in ISR group the negative remodeling degree was obviously higher and the difference between the two groups was statistically significant(x2=6.026,P=0.049).The plaque load in ISR group and non-ISR group was 79.09±8.82 and 69.46±10.49 respectively,and the difference between the two groups was statistically significant(t=3.143,P=0.003).The homocysteine level in ISR group and non-ISR group was(16.02±4.24)mol/L and(12.05±3.34)mol/L respectively,and the difference between the two groups was statistically significant(t=3.717,P＜0.001).In ISR group,there were more significantly contrast-enhanced plaques(78.5％vs.42.3％),with statistically significant difference(x2=6.311,P=0.043).Multivariate logistic regression analysis showed that plaque load(OR=1.225,95％CI:1.040-1.443,P=0.015)and homocysteine level(OR=1.676,95％CI:1.150-2.442,P=0.007)were the independent risk factors for ISR.ROC curve analysis showed that in predicting ISR,the AUC,specificity and sensitivity of the plaque load were 0.765(95％CI:0.622-0.908,P=0.002),0.731 and 0.714 respectively,which of the homocysteine level were 0.767(95％CI:0.623-0.911,P=0.002),0.942 and 0.500 respectively.The combination use of plaque load and homocysteine level could achieve the best predictive effect,its AUC,specificity and sensitivity were 0.887(95％CI:0.794-0.981,P＜0.001),0.904 and 0.714 respectively.Conclusion The plaque load assessed by high-resolution magnetic resonance imaging and the homocysteine level have higher specificity and sensitivity in predicting ISR in patients with middle cerebral artery stenosis.

The present study was aimed to investigate the role and mechanism of glutaminolysis of cardiac fibroblasts (CFs) in hypertension-induced myocardial fibrosis. C57BL/6J mice were administered with a chronic infusion of angiotensin II (Ang II, 1.6 mg/kg per d) with a micro-osmotic pump to induce myocardial fibrosis. Masson staining was used to evaluate myocardial fibrosis. The mice were intraperitoneally injected with BPTES (12.5 mg/kg), a glutaminase 1 (GLS1)-specific inhibitor, to inhibit glutaminolysis simultaneously. Immunohistochemistry and Western blot were used to detect protein expression levels of GLS1, Collagen I and Collagen III in cardiac tissue. Neonatal Sprague-Dawley (SD) rat CFs were treated with 4 mmol/L glutamine (Gln) or BPTES (5 μmol/L) with or without Ang II (0.4 μmol/L) stimulation. The CFs were also treated with 2 mmol/L α-ketoglutarate (α-KG) under the stimulation of Ang II and BPTES. Wound healing test and CCK-8 were used to detect CFs migration and proliferation respectively. RT-qPCR and Western blot were used to detect mRNA and protein expression levels of GLS1, Collagen I and Collagen III. The results showed that blood pressure, heart weight and myocardial fibrosis were increased in Ang II-treated mice, and GLS1 expression in cardiac tissue was also significantly up-regulated. Gln significantly promoted the proliferation, migration, mRNA and protein expression of GLS1, Collagen I and Collagen III in the CFs with or without Ang II stimulation, whereas BPTES significantly decreased the above indices in the CFs. α-KG supplementation reversed the inhibitory effect of BPTES on the CFs under Ang II stimulation. Furthermore, in vivo intraperitoneal injection of BPTES alleviated cardiac fibrosis of Ang II-treated mice. In conclusion, glutaminolysis plays an important role in the process of cardiac fibrosis induced by Ang II. Targeted inhibition of glutaminolysis may be a new strategy for the treatment of myocardial fibrosis.
