Objective To investigate the changes and clinical significance of serum total and high molecular weight adiponectin (HMW APN) levels in type 2 diabetic patients with non-alcoholic fatty liver disease (NAFLD).Methods Serum levels of total adiponectin and HMW APN were measured by ELISA,in 58 type 2 diabetic patients with nonalcoholic fatty liver disease (T2DM with NAFLD group),59 type 2 diabetic patients without nonalcoholic fatty liver disease (T2DM group),and 55 control subjects with normal glucose tolerance and without nonalcoholic fatty liver disease (NC group).Results (1) Alanine transaminase and total cholesterol levels were significantly higher in T2DM with NAFLD group than those in NC group(P<0.01),while body mass index (BMI),aspartate aminotransferase,triglyceride (TG),and fasting insulin were also significantly increased (P<0.05 or P< 0.01),and high density lipoprotein-cholesterol (HDL-C) were significantly decreased compared with those in NC and T2DM groups (P<0.01).(2) Total adiponectin,HMW APN,and the ratio of HMW APN to total adiponectin in T2DM group were lower than those in NC group.Total adiponectin and HMW APN levels in T2DM with NAFLD group were significantly lower than those in T2DM group(P<0.01).(3) Regression analysis showed that homeostasis model assessment insulin resistance index (HOMA-IR),TG,and HDL-C levels were independent predicting factors for total adiponectin and HMW APN levels.TG and BMI were independent risk factors for T2DM complicated with NAFLD,while total adiponectin and HMW APN levels were the protective ones (OR =0.701,0.489,respectively).Conclusions Hypoadiponectinemia may partially play an important role in the development and progression of NAFLD in T2DM.

Objectives:To analyze the prevalence and risk factors of chronic nephropathy among hospitalized gout patients.Methods:537 hospitalized gout patients in Tianjin Medical University Chu Hsien-I Memorial Hospital were enrolled. According to the levels of glomerular filtration rate (eGFR>90 ml/min, 60-90 ml/min and <60 ml/min), patients were divided into normal group, mild chronic nephropathy group and moderate-severe chronic nephropathy group. The height, weight, waist, hip and blood pressure of the patients were measured. Blood samples from elbow vein were collected to measure biochemical indexes. The 24-hour urine was collected to measure creatinine and uric acid. Multivariate regression analysis was used to analyze the related factors that may affect eGFR.Results:The prevalence of chronic nephropathy among gout patients was 46.76%(251/537), which the prevalence of mild chronic nephropathy was 34.82%(187/537), and moderate severe chronic nephropathy was 11.92%(64/537). With the decline of eGFR, the older the patients, the longer the course of gout and hypertension, the more the number of joints involved, the higher the blood uric acid, urinary microalbumin, urinary protein, white blood cell count, uric acid excretion fraction (FeUA), and the lower the red blood cell count, hemoglobin and serum albumin. Pearson correlation analysis of eGFR showed that age, duration of gout and hypertension, number of involved joints, hemoglobin, serum albumin, serum uric acid, urinary microalbumin, and FeUA were correlated with eGFR ( r=-0.43, -0.238, -0.25, -0.128, 0.155, 0.138, -0.169, -0.29, -0.372, respectively, P<0.01). Multivariate regression analysis showed that age, the course of gout, serum uric acid, microalbuminuria and FeUA were independent risk factors for eGFR decline ( P<0.01). Conclusions:Eldly, long course of gout, poor control of serum uric acid and increased excretion of uric acid and microalbumin are risk factors of gout.

OBJECTIVETo delineate the phenotypic characteristics of 22q11.2 deletion syndrome and the role of CRKL gene in the pathogenesis of cardiac abnormalities.
METHODSG-banded karyotyping, single nucleotide polymorphism (SNP) array and fluorescence in situ hybridization (FISH) were performed on a fetus with tetralogy of Fallot detected by ultrasound. Correlation between the genotype and phenotype was explored after precise mapping of the breakpoints on chromosome 22q11.2. SNP array was also performed on peripheral blood samples from both parents to clarify its origin.
RESULTSThe fetus showed a normal karyotype of 46,XY. SNP array performed on fetal blood sample revealed a 749 kb deletion (chr22: 20 716 876-21 465 659) at 22q11.21, which encompassed the CRKL gene but not TBX1, HIRA, COMT and MAPK1. Precise mapping of the breakpoints suggested that the deleted region has overlapped with that of central 22q11.2 deletion syndrome. SNP array analysis of the parental blood samples suggested that the 22q11.21 deletion has a de novo origin. The presence of 22q11.21 deletion in the fetus was also confirmed by FISH analysis.
CONCLUSIONCentral 22q11.21 deletion probably accounts for the cardiac abnormalities in the fetus, for which the CRKL gene should be considered as an important candidate.

OBJECTIVE:To observe the expression of IGF-1R and VEGFR2 in colorectal cancer tissue,and to explore its clinical significance. METHODS:Totally 98 colorectal cancer patients underwent surgery were selected from our hospital during Jan. 2011-Dec. 2012. The tumor tissue and paracancerous tissue were collected. The expression of IGF-1R and VEGFR2 protein were detect-ed by immunohistochemical SP method. The mRNA expression of both were detected by RT-PCR. The correlation of the expression of IGF-1R and VEGFR2 protein with clinical pathological characteristics of colorectal cancer patients were investigated,and its effects on 4-year disease-free survival rate of postoperative assisted chemotherapy patients were also investigated. RESULTS:The positive rates of IGF-1R and VEGFR2 protein expression in colorectal cancer tissue were 66.3%and 60.2%respectively,but their expression was not found in paracancerous tissue,with statistical significance(P<0.05). Relative expression of IGF-1R mRNA and VEGFR2 mRNA in tumor tissue were significantly higher than paracancerous tissue,with statistical significance(P<0.05). There was positive correla-tion between their mRNA expression in tumor tissue(r=0.729,P<0.05). The expression of IGR-1R protein was independent from pa-tient's gender and age,tumor location and formation of vascular tumor thrombus(P>0.05);but it was associated with the histological grading,depth of invasion and lymph node metastasis(P<0.05). The expression of VEGFR2 protein had nothing to do with patient's gender and age(P>0.05),but it was associated with tumor location,histological grading,depth of invasion,lymph node metastasis, and formation of vascular tumor thrombus(P<0.05). Among 98 colorectal cancer patients,14 patients didn't underwent chemothera-py after surgery;and 4-year disease-free survival rate of other 84 patients was 76.2%(64/84). Four-year disease-free survival rates of TGF-1R protein negative expression and VEGFR2 protein negative expression patients(82.8%,78.8%)were significantly higher than those of positive expression patients(72.7%,74.5%),with statistical significance(P<0.05). The multiple factor Logistic regression analysis was used to correct gender,age,histological grading,tumor location,depth of invasion,lymph node metastasis,and forma-tion of vascular tumor thrombus;the expression of IGR-1R and VEGFR2 protein were still associated with 4-year disease-free survival rate [adjusted OR were 2.31,2.15;95%CI were(0.57,4.15),(0.45,4.03);P<0.05]. CONCLUSIONS:The expression of IGF-1R, VEGFR2 protein and mRNAs increase significantly in colorectal cancer tissue;the protein expression is associated with histological grading,depth of invasion,lymph node metastasis and the prognosis of postoperative assisted chemotherapy patients. Their examina-tion can provide reference for target therapy for colorectal cancer patients.

Objective:To explore the status quo of nurses' nursing informatics competency and its relationship with perceived professional benefits and intention to stay, so as to provide a basis for improving nurses' nursing informatics competency and reducing nurses' turnover.Methods:Using the convenient sampling method, nurses from 7 hospitals in Shandong Province were selected as the research objects from June 2020 to June 2021. The survey was conducted using General Information Questionnaire, Self-assessment of Nursing Informatics Competencies Scale (SANICS) , Questionnaire of Nurses' Perceived Professional Benefits and Questionnaire of Nurses' Intention to Renain. A total of 900 questionnaires were distributed in this study and 880 valid questionnaires were recovered, with an effective rate of 97.8%.Results:For 880 nurses, the scores of SANICS, Questionnaire of Nurses' Perceived Professional Benefits Scale and Questionnaire of Nurses' Intention to Renain were respectively (85.54±12.43) , (132.21±19.56) and (22.68±3.84) . The structural variance model showed that the nursing informatics competency of nurses could directly affect the intention to stay (effect value 0.456) , and the nursing informatics competency could also have an indirect effect on the intention to stay through perceived professional benefits of nurses (effect value 0.067) , with a total effect value 0.523.Conclusions:The nursing informatics competency of nurses is at the medium level. By improving the nursing informatics competency, the self-development of nurses can be promoted and their perceived professional benefits can be improved, so as to increase the intention to stay and reduce the turnover of nurses.
