Effect of kaempferol on the proliferation, migration and invasion of cervical cancer cells through circFBXW7 / 国际生物医学工程杂志

Objective:To investigate the effect of kaempferol on proliferation, migration, and invasion of cervical cancer SiHa cells by regulating circFBXW7.Methods:SiHa cells were treated with kaempferol at low, medium, and high doses (15, 30, and 60 μmol/L) for 24 h. Untreated SiHa cells were used as the control group. CCK-8 was used to detect the effect of kaempferol on the proliferation of SiHa cells. Transwell was used to detect the effect of kaempferol on the migration and invasion of SiHa cells. Real-time fluorescence quantitative polymerase chain reaction was used to detect the expression of circFBXW7 in SiHa cells. pcDNA and pcDNA-circFBXW7 were transfected into SiHa cells, respectively, and si-NC and si-circFBXW7 were transfected into SiHa cells after adding 60 μmol/L kaempferol treatment for 24 h. The effects of circFBXW7 and its knockdown, circFBXW7, on the proliferation, migration, and invasion of SiHa cells were investigated, and the effects of E-cadherin and N-cadherin protein expression levels were detected by Western Blot. Results:Compared with the control group, the cell value-added, migration, and invasion abilities of the low, medium, and high dose groups were decreased (all P < 0.05) and were dose-related, and the expression of circFBXW7 was increased ( P < 0.05). After transfection with pcDNA-circFBXW7, the expression of circFBXW7 increased ( P < 0.05), while promoting the proliferation, cell migration, and invasion of kaempferol on SiHa cells (all P < 0.05). After transfection with si-circFBXW7, the expression of circFBXW7 decreased ( P < 0.05), while inhibiting the proliferation, cell migration, and invasion of kaempferol on SiHa cells (all P < 0.05). That indicated that the transfection of si-circFBXW7 could attenuate the inhibitory effects of kaempferol on the above oncogenic phenotypes of SiHa cells. Compared with the control group, E-cadherin expression was upregulated, and N-cadherin expression was downregulated in the low, medium, and high dose groups (all P < 0.05) in a dose-related manner. After transfection of pcDNA-circFBXW7 with SiHa cells, the expression of E-cadherin was increased, and the expression of N-cadherin was decreased (all P < 0.05). After transfection of si-circFBXW7 with SiHa cells, the expression of E-cadherin decreased, and the expression of N-cadherin increased (all P < 0.05). Conclusions:Kaempferol can reduce the proliferation, migration, and invasion abilities of SiHa cells by promoting circFBXW7 expression.

Prognostic nomogram incorporating radiological features for predicting overall survival in patients with AIDS-related non-Hodgkin lymphoma / 中华医学杂志(英文版)

BACKGROUND@#Acquired immune deficiency syndrome (AIDS)-related non-Hodgkin lymphoma (AR-NHL) is a high-risk factor for morbidity and mortality in patients with AIDS. This study aimed to determine the prognostic factors associated with overall survival (OS) and to develop a prognostic nomogram incorporating computed tomography imaging features in patients with acquired immune deficiency syndrome-related non-Hodgkin lymphoma (AR-NHL).@*METHODS@#A total of 121 AR-NHL patients between July 2012 and November 2019 were retrospectively reviewed. Clinical and radiological independent predictors of OS were confirmed using multivariable Cox analysis. A prognostic nomogram was constructed based on the above clinical and radiological factors and then provided optimum accuracy in predicting OS. The predictive accuracy of the nomogram was determined by Harrell C-statistic. Kaplan-Meier survival analysis was used to determine median OS. The prognostic value of adjuvant therapy was evaluated in different subgroups.@*RESULTS@#In the multivariate Cox regression analysis, involvement of mediastinal or hilar lymph nodes, liver, necrosis in the lesions, the treatment with chemotherapy, and the CD4 ≤100 cells/μL were independent risk factors for poor OS (all P < 0.050). The predictive nomogram based on Cox regression has good discrimination (Harrell C-index = 0.716) and good calibration (Hosmer-Lemeshow test, P = 0.620) in high- and low-risk groups. Only patients in the high-risk group who received adjuvant chemotherapy had a significantly better survival outcome.@*CONCLUSION@#A survival-predicting nomogram was developed in this study, which was effective in assessing the survival outcomes of patients with AR-NHL. Notably, decision-making of chemotherapy regimens and more frequent follow-up should be considered in the high-risk group determined by this model.

Diagnosis and treatment of novelcoronavirus pneumonia after kidney transplant: a report of 2 cases / 中华器官移植杂志

Objective:To explore the clinical features and managements of novel coronavirus (2019-nCoV) infection after kidney transplantation.Methods:The authors reviewed medical history, laboratory values, imaging studies, treatment options and clinical outcomes of two confirmed hospitalized cases of COVID-19 after kidney transplant in February 2020. Both cases were middle-aged males and confirmed as COVID-19 at 11 or 12 months after transplantation. They both presented initially with moderate-to-low fever, cough and fatigue. Chest computed tomography (CT) hinted at multiple peripheral patchy ground glass opacities or patchy exudation and in bilateral multiple lobular and subsegmental with obscure boundary. Both had varying degrees of renal function and cardiac insufficiency.Results:In case 1, the dose of immunosuppressants was tapered while a higher dose of glucocorticoids was prescribed during treatment. In case 2, the dose of immunosuppressants was not tapered and continuous renal replacement therapy (CRRT) performed thrice in the early disease course due to renal insufficiency and hyperkalemia. Both cases received oxygen inhalation, lopinavir/ritonavir, oral abidor and interferonα-2b antiviral therapy, antibiotics treatment. Both cases were cured.Conclusions:The clinical manifestations and diagnosis of COVID-19 patients after kidney transplantation are not significantly different from those of other people. However, early renal function and heart function abnormalities occur. How to adjust the immunosuppressant in the treatment course of severe COVID-19 after renal transplantation should be further explored.

Expression of LP-PLA2 mRNA in peripheral blood monocytes subsets of patients with type 2 diabetes mellitus / 中华内分泌代谢杂志

Objective To investigate the role of monocyte subsets in the pathogenesis of type 2 diabetes mellitus(T2DM), the expression was detected on lipoprotein-associated phospholipase A2(LP-PLA2) mRNA in peripheral blood monocytes subsets of type 2 diabetic patients. Methods After the peripheral blood of 32 type 2 diabetic patients and 22 healthy controls were collected,the percentages of the monocytes subsets were detected by flow cytometry. The expression of LP-PLA2 mRNA in monocytes subsets were detected by PCR. After monocyte subsets of healthy subjects were induced into macrophages and stimulated by the serum of type 2 diabetic patients for 24h,LP-PLA2 mRNA expression was detected. Results Compared with the control group, the percentage of classical monocytes in T2DM group was decreased, while the LP-PLA2 mRNA expression and percentage of nonclassical,intermediate monocytes were significantly increased(all P<0.05). In addition,the homeostasis model assessment for insulin resistance index was positively correlated with LP-PLA2 mRNA expression in non-classical(P<0.05)and intermediate monocytes(P<0.01)of type 2 diabetic patients. Compared with type 2 diabetic patients without carotid atherosclerosis, the levels of LP-PLA2 mRNA in intermediate and nonclassical monocytes were significantly higher than those in type 2 diabetic patients with carotid atherosclerosis(P<0.05). The level of LP-PLA2 mRNA in non-classical monocytes-derived macrophages stimulated with the serum of type 2 diabetic patients was significantly higher than that in the control group(P<0.05). Conclusion Monocytes subsets from type 2 diabetic patients are abnormally skewed toward to intermediate and non-classical monocytes with high expression of LP-PLA2 mRNA,which may play an important role in the pathogenesis of type 2 diabetes mellitus and atherosclerosis.

Serum alpha2-Heremans-Schmid glycoprotein levels in subjects with simple overweight and obesity / 中华内分泌代谢杂志

Objective To investigate serum alpha2-Heremans-Schmid glycoprotein ( AHSG ) level and its relationship with associated clinical parameters in subjects with simple overweight and obesity. Methods Forty-nine subjects with obesity ( OB group) , 176 subjects with overweight ( OW group) , and 327 individuals with normal weight ( NW group) were randomly enrolled. The clinical data were collected and serum levels of AHSG and adiponectin ( APN) were determined by ELISA. The associations of serum AHSG level with other clinical parameters were assessed by Pearson correlation analysis and multiple linear regressive model. Results Serum AHSG levels were higher in OW and OB groups than that in NW group[(276. 30 and 302. 10 vs 241. 60)μg/ml], being especially higher in OB group (P<0. 05 or P<0. 01). Serum AHSG level in NW group was positively associated with fasting plasma glucose, homoeostasis model assessment of insulin resistance index, C-reactive protein (CRP), triglycerides, and free fatty acids ( FFA ) , but negatively associated with age and APN. In OW and OB groups, AHSG was also positively associated with body mass index, waist hip ratio(WHR), and low density lipoprotein cholesterol(P<0. 05 or P<0. 01) except the aforementioned clinical parameters. In multiple linear regression model, AHSG was positively associated with WHR, CRP, and FFA, and was negatively associated with APN ( P<0. 05 or P<0. 01). Conclusion The raised AHSG level in overweight and obese subjects may be a risk factor for obesity-related diseases.

Drinking in male HBV carriers in the outpatient department / 中南大学学报(医学版)

OBJECTIVE@#To understand the relation among drinking, characteristics and emotion in outpatient male carriers with hepatitis B virus (HBV), and to provide reference for alcohol intervention.@*METHODS@#We used alcohol use disorders identification test (AUDIT), self-rating anxiety scale (SAS), and Beck depression inventory (BDI) to investigate 980 male HBV carriers in the outpatient department.@*RESULTS@#The questionnaires were responded by 544 people with drinking experience for nearly a year (drinking rate 58.18%). The prevalence of moderate drinking was 37.8% (354 patients), hazardous and harmful drinking 17.97% (168 patients) and alcohol dependence 2.35% (22 patients). In groups with different ages, education levels, occupations, income and symptoms, the constituent ratio of the hazardous harmful drinking and alcohol dependence (AUDIT 7-26 scores) was different (P<0.05). The total score in SAS in the alcohol dependence group was much higher than that in the normal group (35.95±11.55 vs 29.78±0.46, P =0.020); the total score in SAS and in BDI was significantly higher in the alcohol dependence group than that in the moderate drinking group and the hazardous harmful drinking group (35.95±11.55 and 10.45±8.95 vs 29.65±7.97 and 6.35±5.65 vs 29.68±7.06 and 6.44±5.27, respectively).@*CONCLUSION@#Male HBV carriers of 30-49 years old, with education level lower than elementary school or higher than bachelor degree, cadres/professionals with high income and major symptoms show higher harmful/alcohol dependence (AUDIT 7-26 points). Anxiety and depression in the alcohol-dependent male hepatitis B virus carriers are obviously higher than in the moderate drinking group and the hazardous harmful drinking group.
