AIM:To investigate the effects of mitogen-inducible gene 6(MIG6)overexpression on palmitic acid(PA)-induced endoplasmic reticulum stress-associated steatosis in hepatocytes.METHODS:A mouse model of non-alcoholic steatohepatitis was established by feeding twenty C57BL/6J mice a high-fat diet for 26 weeks.The mice were ran-domly divided into two groups:normal diet control group and high-fat diet group,and their livers were retained for subse-quent experiments.The PA was used to induce lipid accumulation in HepG2 cells and AML12 cells,and the cells were di-vided into two groups:BSA(10%BSA)group and PA(500 μmol/L PA)group.The MIG6 overexpression was induced by transfecting HepG2 and AML12 cells with human and mouse MIG6 overexpression plasmids,respectively.The cells were divided into four groups according to their different treatment conditions:(1)negatiive+BSA group(transfected with nega-tive control plasmid+10%BSA);(2)MIG6+BSA group(transfected with MIG6 overexpression plasmid+10%BSA);(3)negative+PA group(transfected with negative control plasmid+500 μmol/L PA);(4)MIG6+PA group(transfected with MIG6 overexpression plasmid+500 μmol/L PA).Lipid accumulation in hepatocytes was assessed by oil red O staining,and RT-qPCR was used to detect the mRNA expression level of MIG6 in liver tissues.The protein levels of MIG6,lipid synthesis-related molecules fatty acid synthase(FASN)and sterol regulatory element-binding protein 1(SREBP1),and endoplasmic reticulum stress-related proteins glucose regulated protein 78(GRP78)and C/EBP homologous protein(CHOP)in hepatocytes were detected using Western blot.RESULTS:High-fat diet increased the triglyceride content in the liver tissue of C57BL/6J mice induced lipid accumulation in hepatocytes and suppressed the mRNA expression level of MIG6(P<0.01).PA intervention increased the protein levels of lipid synthesis-related molecules such as FASN and SREBP1,and endoplasmic reticulum stress markers GRP78 and CHOP in hepatocytes,but inhibited MIG6 protein levels(P<0.01).We transfected hepatocytes with MIG6 overexpression plasmid,which significantly increased MIG6 protein levels,decreased GRP78 and CHOP protein levels in hepatocytes(P<0.01),significantly attenuated PA-induced lipid accumulation in hepatocytes,and down-regulated FASN and SREBP1 protein levels(P<0.01).These results indicate that MIG6 overexpression inhibited PA-induced endoplasmic reticulum stress and attenuated lipid accumulation in hepato-cytes.CONCLUSION:Overexpression of MIG6 inhibits lipid accumulation in hepatocytes by suppressing endoplasmic reticulum stress.

Objective:To analyze the expression levels and clinical significance of interferon (IFN)-α/β in the renal cortex and serum of children with lupus nephritis (LN).Methods:A total of 32 children with LN diagnosed in the pediatric nephrology department of the Second Xiangya Hospital of Central South University from December 2017 to September 2020 were selected as the study subjects (LN group). The normal kidney control group consisted of 3 normal kidney transplant volunteers who underwent biopsy of kidney tissue (normal kidney control group), while 14 healthy children who underwent physical examination were collected as the normal control group. According to the Systemic Lupus Erythematosus Disease Activity Index (SLEDAI), LN patients were divided into mild activity group ( n=8), moderate activity group ( n=9), and severe activity group ( n=15). According to the International Society of Nephrology/Society of Nephrology (ISN/RPS) 2003 LN classification criteria, pathological classification was performed (3 cases in the mild pathological damage group, 8 cases in the moderate pathological damage group, and 11 cases in the severe pathological damage group); Immunohistochemistry was used to detect the expression and distribution of IFN-α/β in glomeruli and renal interstitium; Enzyme linked immunosorbent assay (ELISA) was used to detect the concentration of IFN-α/β in serum samples and analyze its correlation with the pathological classification and disease activity of LN patients. Results:The serum and renal cortex IFN-α/β levels in the LN group were higher than those in the normal control group and normal kidney control group, respectively (all P<0.05). The average level of serum IFN-α/β in the heavy activity group was higher than that in the light and moderate activity groups (all P<0.05). The serum and renal cortex IFN-α/β levels in the severe pathological damage group were significantly higher than those in the mild and moderate pathological damage groups (all P<0.05). Conclusions:IFN-α/β in the renal cortex is closely related to renal injury in LN; Serum IFN-α/β can assist in evaluating the disease activity level of LN to a certain extent.

Objectives:To investigate the relationship between visceral adipose index and glomerular filtration rate in patients with type 2 diabetes mellitus.Methods:A total of 1 036 patients with type 2 diabetes mellitus who received treatment in The Second Affiliated Hospital of Xi'an Jiaotong University from May 2017 to May 2018 were included in this study. The visceral adipose index was detected using a bioresistance assay. These patients were divided into four groups using the quartile method: Visceral adipose index < 8.10 (q1 group, n = 246), 9.60 > visceral adipose index ≥ 8.10 (q2 group, n = 64), 11.10 > visceral adipose index ≥ 9.60 (q3 group, n = 423), visceral adipose index ≥ 11.10 (q4 group, n = 233). One-way analysis of variance was performed to compare the differences among groups. Partial correlation and multiple regression were used to analyze the correlation between body mass index, waist circumference, waist-to-height ratio, waist-to-hip ratio, body fat content, visceral adipose index, and urinary microalbumin and glomerular filtration rate. Results:With the increase in the visceral adipose index, the glomerular filtration rate gradually decreased. The glomerular filtration rate in the q1, q2, q3, q4 groups was (112.19 ± 31.74) mL·min -1·1.73 m -2, (106.14 ± 28.26) mL·min -1·1.73 m -2, (104.73 ± 23.63) mL·min -1·1.73 m -2, (103.40 ± 27.51) mL·min -1·1.73 m -2, respectively. In the female group, with the increase in visceral adipose index, the glomerular filtration rate decreased gradually. After controlling for age, sex, diabetes, and hypertension, the visceral adipose index was significantly correlated with the glomerular filtration rate ( r = -0.10, P < 0.001). Multiple regression analysis showed that visceral adipose index and waist-to-height ratio were closely related to glomerular filtration rate ( F = 6.00, P < 0.001). Conclusion:With the increase of visceral adipose index, body mass index, waist circumference, waist-to-height ratio, waist-to-hip ratio, body fat content, and urinary microalbumin increased gradually. When the visceral adipose index is greater than 9.60, the glomerular filtration rate is significantly decreased. Therefore, it is suggested to adopt various methods to evaluate obesity in clinical work, and visceral fat index should be paid more attention, especially when the visceral fat index is greater than 9.60.

Objective:To explore the difference of clinical characteristics between senile Parkinson's disease(PD)with depression and unipolar depression.Methods:From March 2019 to March 2020, 53 patients with Parkinson's disease depression and 57 patients with unipolar depression who were admitted to the neurology department of Beijing Hospital were continuously collected.The gender, age and education level of the patients were recorded.The course of disease and other general data of the patients with Parkinson's disease were also recorded.Depression and anxiety of the patients were evaluated by Beck Depression Inventory(BDI)and Generalized Anxiety Disorder Scale(GAD-7). Quality of life of patients with Parkinson's disease was evaluated by 8-item Parkinson's disease questionnaire(PDQ-8). Differences in the assessment results and quality of life scores between the two groups were analyzed.Results:The incidence of depression comorbid with anxiety in elderly PD patients was 52.8%(28/53), lower than that in elderly unipolar depression patients comorbid with anxiety [84.2%(48/57)]( χ2=12.664, P<0.001). The scores of activity inhibition [(1.8±0.8)points]and hyposexuality [(0.4±1.0)points]in elderly PD patients with comorbid depression were higher than that in patients with unipolar depression [(1.1±0.8)points, (0.0±0.0)points]( t=4.399, 2.942, P<0.001, =0.005). Moreover, the incidence of activity inhibition(98.1%)and hyposexuality(15.1%)in PD patients with comorbid depression was higher than that in patients with unipolar depression(78.9%, 0.0%)( χ2=9.680, 9.279, both P=0.002). The scores of self-blame [(1.0±0.8)points]and pain [(1.0±0.8)points]in elderly patients with unipolar depression were higher than those in PD patients with comorbid depression [(0.5±0.7)points, (0.9±0.7)points]( t=-3.902, -2.486, P<0.001, =0.014). Moreover, the incidence of self-blame(66.7%), irritability(78.9%)and image distortion(56.1%)in elderly patients with unipolar depression was higher than that in PD patients(35.8%, 56.6%, 35.8%)( χ2=10.447, 6.320, 4.547, P=0.001, 0.012, 0.033). The scores of PDQ-8 in PD patients with comorbid depression and anxiety [14.8(10.8, 19.0)points]( Z=-3.544, P<0.001)were higher than those in PD patients with depression only [7.0(4.8, 11.0)points]. Conclusions:The focus of depression in elderly PD patients is different from that in elderly unipolar depression patients.Elderly patients with unipolar depression are more likely to be comorbid with anxiety.Depression reduces the quality of life in PD patients, and the comorbidity of anxiety further reduces the overall quality of life in PD patients with depression.

To establish a disease risk prediction model based on genetic susceptibility genes and environmental risk factors, which can target high-risk population as early as possible, and intervene in the environmental risk factors in this population. Moreover, accurate screening of genetically susceptible populations can enhance the efficiency of health system. In recent years, with the maturation and cost reduction of high-throughput gene testing, gene testing has been widely used in individual clinical decision-making and will play a more important role in medical and health decision-making. The correlation between genetic testing and disease risk prediction is increasing, making it a prominent research topic in this field. This review summarizes the approaches for establishing and evaluating risk prediction models and discusses potential future challenges and opportunities.

Objective:To investigate the unqualified hepatitis C virus (HCV) detection result of blood donors from the served area of blood institutions.Methods:The data related to HCV markers detected of the first and repeat blood donors were collected from the system of practice comparison for the Chinese mainland blood institutions from 2017 to 2021. The anti-HCV reactive rate and the rates of anti-HCV negative but HCV-RNA reaction and all the relationship between rates and the annual, regional and different blood donors were statistically analyzed.Results:During 2017-2021, the number of anti-HCV reactive per 100 000 blood donors decreased from 444.3 to 250.44 in the served area of 22 blood institutions ( χ2=49.677, P<0.05). The number of HCV RNA detected positive per 100 000 anti-HCV negative increased from 0.69 to 2.05 year by year, but there was no statistical significance ( χ2=0.643, P>0.05). The anti-HCV unqualified rate was significantly different among regions ( χ2=3 260.283, P<0.05). The anti-HCV unqualified rate of the first blood donors was significantly higher than that of the repeated blood donors ( F=130.993, P < 0.05). The annual number of HCV RNA detected positive per 100 000 anti-HCV negative blood samples from donors ranged from 0 to 17.28. Conclusions:The anti-HCV unqualified rate of blood donors in the served area of 22 blood institutions decreased year by year. Compared with repeated blood donors, HCV infection should be emphasized in first-time blood donors. The implementation of HCV RNA test can detect out much more HCV infections and reduce the risk of transfusion transmitted infectious HCV.
