Objective To investigate the correlation between fasting plasma glucose(FPG)and body mass index(BMI)among examination groups in Baoji area.Methods 55 328 cases of medical examination were measured height,weight and calculated BMI,then these were detected FPG,the test results were analyzed by statistics.Results The levels of FPG and BMI were significant differences between different gender groups and different age groups;Male and female with abnormal FPG detec-tion rates were 9.90%,5.50%;FPG abnormal detection rate of male higher than female (χ2=335.47,P<0.005).The sub-j ects were divided into four groups according to their BMI:low-weight,normal,overweight and obesity.The relevance ratio of 4 groups with abnormal FPG were 2.71%,5.93%,11.65% and 13.75%,with diabetes were 1.38%,3.18%,6.02% and 6.39%,with impaired fasting glucose (IFG)were 0.8%,2.75%,5.64% and 7.37%.The detection rate of abnormal FPG, IFG and DM detection rate increased with increasing BMI levels (P<0.005).Conclusion The levels of FPG was upward trend with increasing BMI,increased prevalence of diabetes in overweight and obese people.The middle-aged population is the focus of monitoring and intervention of obesity.Control BMI is an effective measure to reduce the occurrence of diabetes.

Background Hypertension and dyslipidemia are the 2 important risk factors of cardiovascular affecting the prognosis of cardiovascular disease. However paucity data of characteristics of lipid metabolism and prognosis of cardiovascular diseases in high-risk groups with hypertension are available. Objective To analyze the lipid metabolism level and the relevant risk factors of inpatients with essential hypertension (EH) from 2000 to 2007. Methods Retrospective study was performed based on the clinical characteristic and the relationship between different kinds of hyperlipidemia and target organ damages in inpatient with EH. Results For the level of triglyceride (TG) and the prevalence of hypertriglyceridemia,males(n=3056) were significantly higher than females(n=1932)(P

Objective To evaluate the standardization of diagnosis and therapy for stage I epithelial ovarian cancer.Methods Retrospective study of 146 cases of ovarian cancer admitted in our hospital. All of cases had postoperative pathological diagnosis.Results 146 cases of epithelial ovarian cancer from Jan 1980 to Jun 2002. 32 of them were stage I cases (21 92%). The average age was 45 32. The first four symptom were self touching the mass, abdomen bulge,abdomen pain and oppress symptoms. All of 29 cases accepted surgery and chemotherapy in our hospitalexcept that 3 cases.4/32 lost touch ,3/32 died of other diseases, 5/32 recurrence, 3/32 died of cancer.Five-year survival rates were 92 87%, ten-year survival rates were 83 90%. Conclusions Prognosis between early and advanced ovarian cancer is obvious difference. If the diagnosis and therapy for epithelial ovarian cancer is early,and survival rates is highly.

Objective A high performance liquid chromatographic (HPLC) method was established for the simultaneous determination of xylitol and L-xylulose in fermentation broth.Methods The chromatographic conditions were as follows:C18 column (250 mm ×4.6 mm) with the temperature 35℃, acetonitrile-water (85∶15,v/v)as mobile phase with the flow rate of 0.8 mL/min.Xylitol was detected by refractive index (RI) detector at 33℃and L-xylulose was determined by ultraviolet ( UV) detector at 210 nm at room temperature.Results This method showed good linearity over the range from 0.50~30.00 g/L with a correlation coefficient of 0.9995 for xylitol and 0.30~30.00 g/L with a correlation coefficient of 0.9986 for L-xylulose. Moreover, the limit of quantification (LOQ) for xylitol and L-xylulose were 0.58 and 0.40,respectively.The limit of determination (LOD) for xylitol and L-xylulose were 0.18 and 0.15,respectively.The relative standard deviations (RSDs) of intraday and interday for xylitol were less than 0.64%and 0.80%,respectively.The intraday and interday RSDs for L-xylulose were less than 0.31%and 0.59%.The recoveries of xylitol and L-xylulose in fermentation broth were between 99.00%-101.00%.Conclusion There was no interference from other constitutes in the fermentation broth by this method.The methods were suitable for the simultaneous determination of the substrate xylitol and the product L-xylulose in fermentation process.

Objective To evaluate the clinical value of bone alkaline phosphatase in early diagnosis and treatment effect of chil-dren′rickets and to understand the incidence rate of rickets in children in the local region by the detection of neonatal bone alkaline phosphatase(NBAP).Methods 2 184 children with physical examination in our hospital from January to December 2013 were se-lected and divided into the infants,young children,preschool and school-age children groups according to age.The finger blood was collected for detecting the bone alkaline phosphatase in the peripheral blood by the bone alkaline phosphatase reagent kit provided by Beijing Jinyu diagnosis technology Co.,Ltd.Results Among detected 2 184 children,the detection rate of clinical rickets(NBAP>250 U/L)was 10.1 %,moreover the smaller the age,the higher the detection rate;the detection rate of subclinical rickets(NBAP 200~250 U/L)was 65.5%,indicating that most children in Baoji region were in sub-health state;the detection rate in spring and winter was higher than that in summer and autumn;the detection rate of NBAP had no gender difference.Conclusion Children are in the rapid growth and development period,easy to suffer from vitamin D deficiency,the activity detection of NBAP has important clinical value in the early diagnosis of rickets caused by vitamin D deficiency.Prevention should begin from perinatal period and NBAP should be timely detected in order to conduct early diagnosis and early treatment.

Objective:To investigate the value of radiomics nomogram based on standardized pre-treatment chest enhanced CT in predicting the mutation status of epidermal growth factor receptor (EGFR) for patients with lung adenocarcinoma.Methods:A retrospective analysis was conducted on pre-treatment chest enhanced CT images and clinical data of 262 patients from the affiliated hospital of Jining Medical University with pathologically proven primary lung adenocarcinoma who received EGFR gene testing, including EGFR wild type ( n=122) and mutant type ( n=140). The patients were divided into training group ( n=183) and testing group ( n=79) according to a ratio of 7∶3 by stratified sampling method. Standardized pre-processed the images, delineated the ROI and extracted the radiomics features. Least absolute shrinkage and selection operator (LASSO) algorithm was used to reduce the dimension and select key features. The standardized radiomics model, clinical model and the combined model were established by Logistic Regression (LR) machine learning method. Calculated the Rad-score and drew the nomogram. ROC curve and Delong were used to evaluate and compare the predictive performance of different models. Results:23 standardized enhanced CT radiomics features and 4 clinical features were selected. The predictive performance of standardized radiomics model was better than that of non-standardized radiomics model [area under curve (AUC): 0.863 vs. 0.805, t=2.19, P<0.05]. The AUCs of the combined model and standardized radiomics model were higher than that of the clinical model (training group: 0.885, 0.863 vs. 0.774, t=3.57, 2.17, P<0.05; testing group: 0.873, 0.829 vs. 0.763, t=2.19, 2.02, P<0.05). The radiomics nomogram was built based on Rad-score, age, sex, smoking history and BMI. Conclusions:The combined model and standardized radiomics model could effectively predict the mutation status of EGFR gene in lung adenocarcinoma patients before treatment, providing valuable clinical insights.
