Background/Aims: Low educational attainment is a well-established risk factor for nonalcoholic fatty liver disease (NAFLD) in developed areas. However, the association between educational attainment and the risk of NAFLD is less clear in China. Methods: A cross-sectional study including over 200,000 Chinese adults across mainland China was conducted. Information on education level and lifestyle factors were obtained through standard questionnaires, while NAFLD and advanced fibrosis were diagnosed using validated formulas. Outcomes included the risk of NAFLD in the general population and high probability of fibrosis among patients with NAFLD. Logistic regression analysis was employed to estimate the risk of NAFLD and fibrosis across education levels. A causal mediation model was used to explore the potential mediators. Results: Comparing with those receiving primary school education, the multi-adjusted odds ratios (95% confidence intervals) for NAFLD were 1.28 (1.16 to 1.41) for men and 0.94 (0.89 to 0.99) for women with college education after accounting for body mass index. When considering waist circumference, the odds ratios (95% CIs) were 0.94 (0.86 to 1.04) for men and 0.88 (0.80 to 0.97) for women, respectively. The proportions mediated by general and central obesity were 51.00% and 68.04% for men, while for women the proportions were 48.58% and 32.58%, respectively. Furthermore, NAFLD patients with lower educational attainment showed an incremental increased risk of advanced fibrosis in both genders. Conclusions In China, a low education level was associated with a higher risk of prevalent NAFLD in women, as well as high probability of fibrosis in both genders.

The data of 10 patients with pituitary metastases were retrospectively analyzed, including tumor origin, clinical features, imaging characteristics, diagnosis and differential diagnosis, treatment and prognosis. The results showed that the average age of 10 patients at the time of consultation was 62.0 years. Nine metastases were originated from lung cancer and one from breast cancer. All patients started with central diabetes insipidus, and some of them accompanied with hypopituitarism, as well as occupancy manifestations such as headache, blurred vision, etc. MRI showed abnormalities in the pituitary stalk and posterior pituitary, four of which showed characteristic " dumbbell-shaped" changes. Three patients with epidermal growth factor receptor(EGFR)-mutated lung adenocarcinoma revealed improvement in both primary lesion and pituitary metastases after targeted therapy.

【Objective】 To analyze and mine the prescription rules of traditional Chinese medicine enema treatment of chronic kidney disease （CKD） in CNKI platform journals based on data mining and network pharmacology so as to find high-frequency core Chinese medicines and predict the potential targets of core Chinese medicines and explore the mechanism of action of core Chinese medicines in the treatment of CKD. 【Methods】 Taking CNKI as the data source， we retrieved the clinical literature of traditional Chinese medicine enema in the treatment of CKD. SPSS modeler 18.0 statistical software was used for statistical processing and association rule analysis. IBM SPSS statistics 21 statistical software was used for cluster analysis. BATMAN-TCM and TCMSP were used to retrieve the effective components and related targets of drugs. Genecards， OMIN， Drugbank， DisGenet， TTD， and PharmGkb databases were used to retrieve disease-related targets， and Venny platform was used to screen disease and drug intersection targets. We used STRING database to obtain relevant documents， Cytoscape 3.8.2 software for visual analysis， Metascape database for enrichment analysis， Wechat website to draw bubble diagram， and AutoDockTools-1.5.6 software for molecular docking prediction. 【Results】 We selected 276 effective prescriptions involving 120 traditional Chinese medicines. The frequency of 19 traditional Chinese medicines was more than 10. Totally 18 core drug combinations were obtained. Cluster analysis could be divided into four categories. The visual net-work analysis shows that “rhubarb， dandelion， oyster， Salvia miltiorrhiza and aconite” are highly correlated and occupy the core position. Through the prediction of the potential targets of five core drugs， 659 “drug disease” intersection targets and 173 core targets were obtained， of which “MAPK1， AKT1 and STAT3” are the key targets， “progesterone， neocryptotanshinone Ⅱ and emodin”. It is predicted that it may play a role in “PI3K Akt signal pathway， MAPK signal pathway， JAK-STAT signal pathway”. Molecular docking showed that the key components have good binding activity with key targets. 【Conclusion】 Based on data mining and network pharmacology， traditional Chinese medicine enema treatment of CKD mainly uses rhubarb as the main drug， assisting warming yang to remove blood stasis and turbidity relief drugs. The key components of its core drug can act on PI3K-Akt by regulating key targets such as PIK3R1. Signal pathways and other pathways play a role in providing new ideas for the treatment of this disease with traditional Chinese medicine enema， medication strategies for clinical prescriptions， and a basis for follow-up further research.

Objective:To observe the effect of shift work on the stability of the circadian clock and insulin sensitivity in non-overweight/obese individuals with normal blood glucose, and explore underlying connection.Methods:Female shift working nurses in the Department of Blood Transplantation and non-shift working nurses in the Health Management Center in the First Affiliated Hospital of Zhengzhou University were divided into shift worker group (SW group) and non-shift worker group (NSW group). Serum inflammatory factors [interleukin-6 (IL-6), tumor necrosis factor-α(TNF-α)], adipokines (adiponectin, leptin, chemerin, visfatin), and melatonin levels were measured using enzyme linked immunosorbent assay (ELISA). Realtime fluorescence quantitative PCR was performed to detect peripheral blood circadian clock genes circadian locomotor output cycles protein kaput(Clock) and brain and muscle ARNT-like protein 1(Bmal1). Cortisol and fasting insulin were measured by chemiluminescent microparticle immunoassay, and HbA 1C was measured by capillary electrophoresis. In addition, visceral fat area (VFA) was assessed with bioelectrical impedance analyzer, and mid-sleep time composite phase deviations (CPD) was calculated based on the International Physical Activity Short Questionnaire. Results:SW group had lower serum level of melatonin ( P=0.023) and higher cortisol ( P=0.001) than the NSW group, and altered mRNA expression of Clock and Bmal1 ( P=0.034, P=0.047). Fasting blood glucose and HbA 1C in the SW group, although in the normal range, had been higher than in the NSW group ( P=0.011, P=0.033). Although body mass index was normal in SW group, VFA had been higher than that of the NSW group ( P=0.010). And homeostasis model assessment for insulin resistance (HOMA-IR), IL-6, TNF-α, leptin, chemerin, and visfatin were significantly higher in the SW group than NSW group ( P=0.033, P=0.012, P=0.001, P=0.011, P=0.021, P=0.007). In addition, adjusting for body mass index and activity factors revealed a significant positive correlation between CPD and VFA ( r=0.434, P=0.049), inflammatory factors IL-6 ( r=0.514, P=0.017) and TNF-α ( r=0.700, P<0.001) and pro-inflammatory adipokines leptin ( r=0.473, P=0.030), chemerin ( r=0.439, P=0.047), visfatin ( r=0.521, P=0.015). Conclusion:Shift work can affect circadian clock, with increased visceral adiposity, pro-inflammatory adipokines, inflammatory factors and decreased insulin sensitivity in women without overweight/obese.

Objective:To observe the effects of continuous light exposure on skeletal muscle fiber type transformation and lipid metabolism, and to explore its internal relationship.Methods:Mice were randomly divided into normal light group and 24-hour continuous light group by random number table. The serum and skeletal muscle lipid content and urine 6-sulfatoxymelatonin(6-SML)level were detected by ELISA. The expression of circadian clock and lipid metabolism related genes mRNA were observed by realtime PCR. The muscle fiber type and lipid deposition were evaluated by tissue immunofluorescence as well as oil red O staining.Results:Compared with the normal light group, the level of 6-SML in urine at night decreased( P<0.05), and the expression level and rhythm of brain and muscle ARNT-like protein 1(Bmal1), circadian locomotor output cycles protein kaput(Clock), and period 2(Per2)mRNA in the skeletal muscle changed in continuous light group. In addition, the body weight, blood lipid, free fatty acid, and triglyceride contents of skeletal muscle in continuous light group increased significantly( P<0.05 or P<0.01), the expression of carnitine palmitoyltransferase 1b (Cpt1b)mRNA, the key enzyme of fatty acid oxidation, decreased significantly( P<0.05), while the expression of stearoyl-CoA desaturase(Scd1)mRNA, a lipid synthesis related gene, increased significantly( P<0.01). Further immunofluorescence analysis showed that the proportion of slow muscle fibers decreased and that of fast muscle fibers increased in continuous light group(both P<0.05). Conclusion:The process of ectopic deposition of lipid in skeletal muscle in mice induced by continuous light exposure may be related to the remodeling of skeletal muscle fibers.

Objective:To investigate the effect of miR-425-5p on glucagon-like peptide-1(GLP-1) secretion in intestinal L cells induced by lipopolysaccharide(LPS), and to explore its mechanism.Methods:GLUTag cells of intestinal L cell line were incubated with LPS to determine the levels of miR-425-5p and GLP-1. Cell viability was determined by MTT assay, and cell apoptosis was detected by flow cytometry. Quantitative real time-PCR and western blot were performed to determine the expressions of miR-425-5p, phosphatase and tensin homology(PTEN), proglucagon, and GLP-1. Activity of Wnt/β-catenin signaling pathway was determined by detecting TOP/FOP ratio. Interaction among miR-425-5p, PTEN, and β-catenin was analyzed using luciferase activity assay and chromatin immunoprecipitation(ChIP)assay.Results:In GLUTag cells, with the elevation of LPS concentration, the expression of miR-425-5p and the apoptosis rate were increased, while the level of active GLP-1 and the cell viability were decreased. MiR-425-5p was involved in the regulation of LPS on GLP-1 secretion and intestinal L cell viability. Inhibition of miR-425-5p reduced the mRNA expression of proglucagon and the TOP/FOP ratio, increased PTEN protein level, and inhibited cell viability. In LPS-treated GLUTag cells, miR-425-5p increased the level of β-catenin by targeting PTEN, and β-catenin acted as a cis-acting element to induce the transcription of proglucagon and promote the secretion of GLP-1.Conclusion:In LPS-induced intestinal L cells, miR-425-5p promotes the expression of GLP-1 by targeting PTEN to modulate β-catenin.

Objective:To investigate the current situation and influencing factors of home-based self-management ability of patients with schizophrenia and to provide theoretical basis for clinical nursing intervention.Methods:This study is a cross-sectional study. Using the convenient sampling method, a total of 220 patients with schizophrenia who were admitted to Outpatient Department of a Class Ⅲ Grade A Psychiatric hospital in Beijing from June to December 2019 were selected as the research objects. The General Information Questionnaire and Home-based Self-management Scale for Patients with Schizophrenia were used to investigate.Results:In this study, a total of 220 questionnaires were distributed and 207 valid questionnaires were returned. The effective recovery rate was 94.09%. The score of Schizophrenia Self-Management Instrument Scale was (63.51±9.55) , and the scoring rate was 47.58%. Univariate analysis showed that, the scores of Home-based Self-management Scale for Patients with Schizophrenia with different ages, marital status, education levels, working status, household monthly income per capita, living status, economic burden, courses of disease, times of hospitalization, family attitudes and social supports showed statistically significant differences ( P<0.05) . Multivariate analysis showed that, age, marital status, social support and economic burden were the influencing factors of home-based self-management ability of schizophrenia patients ( P<0.05) , accounting for 36.0% of the total variation. Conclusions:The home-based self-management ability of patients with schizophrenia needs to be improved urgently. Medical staff should implement nursing intervention or self-management education according to the different characteristics of patients to effectively improve the self-management ability of patients, promote the recovery of the disease, reduce the recurrence rate and improve quality of life.

Objective:To explore the distribution of serum TRAb IgG subtypes in patients with thyroid-associated ophthalmopathy(TAO) at different stages and its value in assessing TAO activity.Methods:Forty-three patients with TAO, 30 patients with Graves′ disease (GD group), 19 patients with Hashimoto′s thyroiditis (HT group), and 50 healthy subjects (NC group)admitted to the First Affiliated Hospital of Zhengzhou University were collected from August 2018 to February 2019. According to the clinical activity score (CAS), the patients with TAO were further divided into the active period group (AP group, CAS≥3 points, 22 cases) and the inactive period group (IP group, CAS<3 points, 21 cases). The basic clinical data of subjects in each group were collected. The serum concentrations of FT 3, FT 4, TSH, thyroperoxidase antibody (TPOAb), thyroglobulin antibody (TgAb), and thyroid-stimulating hormone receptor antibody (TRAb) were detected by chemiluminescence immunoassay and the binding rate in percentage (B) of serum TRAb IgG and IgG subtypes were detected by ELISA. The positive rate in each group and relative content of positive samples were compared. Results:(1)Compared with HT group, the positive rates of IgG1 and IgG2 in TAO group and GD group were significantly decreased ( P<0.05). There was no significant difference in the relative content of positive TRAb IgG subtype among these disease groups ( P>0.05). (2)Compared with the IP group, IgG1(B) and the positive rates of IgG1 in the AP group were increased while IgG4(B) and the relative contents of IgG4 were reduced ( P<0.05). (3)IgG1(B)was positively correlated with TAO activity ( B=6.190, P=0.007), and higher IgG4(B)indicated more inclinations to the inactive period ( B=-16.390, P=0.052). (4) The area under the curve of receiver operating characteristic (ROC) for TAO developing into active period assessed by activity rate was 0.859 (95% CI 0.746-0.973, P<0.05). When the activity rate was 4.29, the Jordon index showed the largest, with sensitivity of 81.8% and specificity of 81.0%. Conclusions:Elevated levels of TRAb IgG1 in the patients with TAO indicate a tendency to active period, while elevated levels of TRAb IgG4 indicate a tendency to inactive period. The activity rate can provide a reference for assessing whether TAO is active or not.

Objective:To investigate the association of abdominal fat distribution with glycolipid metabolism and diabetic complications in patients with T2DM.Methods:Totally 357 inpatients with T2DM were collected from the Endocrinology Department of our hospital. All patients received quantitative computed tomography to measure the visceral adipose tissue (VAT) and subcutaneous adipose tissue (SAT), and were divided into three groups depending on the tertile of VAT value: T1 group (VAT<162.0 cm 2), T2 group (162.0≤VAT<221.1 cm 2), T3 group (VAT≥221.1 cm 2). The incidences of diabetic kidney disease, diabetic retinopathy, diabetic peripheral neuropathy, peripheral atherosclerosis, and cardia-cerebrovascular disease were examined in all patients. Results:HbA 1C level in T1 group was higher than that in T3 group( P<0.05). High density lipoprotein-cholesterol (HDL-C) and estimated glomerular filtration rate (eGFR) in T1 group were higher compared with those in T2 and T3 groups ( P<0.05). Male proportion, age, body mass index (BMI), systolic blood pressure (SBP), diastolic blood pressure (DBP), triglyceride (TG), 24h urinary albumin, diabetic kidney disease and peripheral atherosclerosis in T2 and T3 groups were higher than those in T1 group ( P<0.05). Fasting C- peptide (FCP) and modified homeostasis model assessment for insulin resistance (HOMA-IR) in T3 group were higher than those in T1 and T2 group ( P<0.01). VAT and SAT were positively correlated with BMI, FCP, and HOMA-IR (p<0.01). VAT was positively correlated with age, SBP, DBP, TG, 24h urinary albumin, diabetic kidney disease, peripheral atherosclerosis, and cardia-cerebrovascular disease ( P<0.05), while inversely correlated with HbA 1C, HDL-C, and eGFR ( P<0.05). SAT was positively correlated with total cholesterol and low density lipoprotein-cholesterol ( P<0.01), while negatively correlated with peripheral atherosclerosis ( P<0.01). Multivariate logistic regression analysis showed that VAT was still a risk factor for diabetic kidney disease after adjusted by age, BMI, SBP and fasting plasma glucose( P=0.013). Conclusion:VAT and SAT are associated with blood lipids and insulin resistance, while VAT seems to be a risk factor for diabetic kidney disease.
