Objective To analyze the relation between glycosylated hemoglobin (HbA1c) and coronary heart disease (CHD) among diabetic and non-diabetic individuals.Methods A total of 1190 in patients from January 2009 to September 2009 were selected and divided into two groups:225 patients with diabete mellitus and 965 patients without.We collected the age,sex,triglyceride ( TG),total cholesterol ( CHO),high-density lipoprotein ( HDL-C),low-density lipoprotein ( LDL-C),fasting blood-glucose (FBG),glycosylated hemoglobin (HbA1c),high-sensitivity CRP (hs-CRP) and analyzed the relation between these indexes and CHD in diabetic and non-diabetic individuals respectively,then,analyzed the difference of HbA1c between patients with and without CHD after correcting the differentiating factor with a multivariable-adjusted model.Meanwhile,according the HbA1c level,we divided all participants into four groups:4.0％ -5.4％( Ⅰ),5.5％ -5.9％ ( Ⅱ),6.0％ -6.4％ ( Ⅲ),≥6.5％ ( Ⅳ),and observed the distribution of HbA1c and coronary heart disease in diabetic and non-diabetic individuals respectively.Results ( 1) In non-diabetic individuals,statistically significant difference of male( 80.5％ υs 62.7％),age [ ( 59 ±11) years υs (55 ± 11) years],FBG [(5.62 ± 1.48) mmol/L υs (5.30 ±0.84) mmol/L],HbA1c [(5.98±0.92)％ υs (5.65 ±0.53)％],CHO [(4.48 ±1.01) mmol/L υs (4.77 ±1.04) mmol/L],LDL-C [(2.59±0.87) mmol/L υs (2.79 ±0.86) mmol/L],HDL-C [(1.08 ±0.26) mmol/L υs(1.21 ±0.32) mmol/L] was observed between patients with and without CHD (P ＜0.01),however,in diabetic individuals,only LDL-C [ ( 2.56 ± 0.81) mmol/L υs ( 3.07 ± 0.90) mmol/L],CHO [ (4.44 ±0.95) mmol/L υs ( 5.08 ± 1.16) mmol/L] were observed ( P ＜ 0.0 1).(2) In all participants,the higher of HbA1c,the higher of CHD percent,compared to patients without CHD,the percent of high HbA1c in CHD patients was significantly higher.After adjusting for age,sex,HDL-C,HbA1c was an independent risk marker for CHD in non-diabetic individuals ( OR:1.935,95％ CI:1.356 - 2.762,P ＜ 0.05),however,links between FBG in the non-diabetic range and CHD appeared weaker after controlling indexes listed above( OR:1.507,95％CI:1.082 -2.098,P＜0.05).Conclusion HbA1c is an independent risk factor for CHD in nondiabetic individuals and prior to FBG.

Objective To explore the vitamin D nutritional status of urban residents in Jinan,in order to provide the basis for the prevention and treatment of chronic diseases associated with vitamin D insufficiency.Methods 1478 cases aged 30-90 years,including 602 men (59.8± 13.0) years on average and 876 women (57.4±12.9) years on average were selected by a stratified random sampling from 3 community medical care institutions in Jinan.Subjects were divided into six groups according to the 10-year interval.Serum 25-hydroxyvitamin D [25(OH) D] level was measured by enzyme-linked immunosorbent assay (ELISA).Serum [25(OH) D] level ≥ 75 nmol/L was defined as vitamin D sufficient,(50.0 ～ 74.9) nmol/L as vitamin D critical value,25.0 ～ 49.9 nmol/L as vitamin D insufficiency,＜ 25 nmol/L as vitamin D deficiency.All data processing and statistical analysis were finished by SPSS 13.0.Results The average level of [25 (OH) D] was 58.60 nmol/L in males [95％ CI:56.7-60.5 nmol/L] and 54.17 nmol/L in females [95％ CI:52.8-55.8 nmol/L],which were less than 75 nmol/L.The average level of [[25(OH) D] was 49.1nmol/L in females aged 70-79 years (95％CI:45.7～52.5 nmol/L),41.7 nmol/L in females aged 80-90 years (95％CI:38.2 ～46.7 nmol/L),which were less than 50 nmol/L.The percentage of cases with vitamin D deficiency,insufficiency,critical value,and sufficiency was 5.6％,33.4％,36.5％,24.4％ in males,and 6.5％,42.9％,32.6％,18.1％ in female respectively.The incidence of vitamin D deficiency and insufficiency was increased with ageing (male:x2 =33.68 P＜0.01,female:x2 =55.7,P＜0.001).The percentage of vitamin D deficiency and insufficiency was more in females than in males (60-69 years old:x2=9.387,P＜0.05,80-90 years old:x2=8.896,P＜0.05).The [25 (OH) D] level was lowest in winter (48.8 nmol/L,95％CI:46.8～50.9 nmol/L) and highest in autumn (60.2 nmol/L,95％ CI:58.0～62.3 nmol/L).The incidence of vitamin D deficiency and insufficiency was highest in winter (x2 =18.364,P＜0.05).Conclusions Vitamin D deficiency and insufficiency are widely prevalent in urban residents,which is more severe in the elderly and females.Serum [25(OH) D] level is related to season,and the vitamin D deficiency and insufficiency are severe in winter.

Objective To investigate the value of vessel size index(VSI) in grading oligodendroglioma by vessel size imaging technique. Methods Twenty-four histologically confirmed oligodendroglioma cases were enrolled (13 gradeⅡand 11 gradeⅢ) . All patients underwent conventional MRI scanning, followed by multi gradient-echo spin-echo sequence from dynamic susceptibility contrast perfusion to generate VSI maps. Region of interests were contoured on VSI color maps to obtain hot-spot value of mean VSI of microvasculature (VSImean) and maximum VSI of microvasculature (VSImax). Paraffin sections of each case was stained with CD34 to acquire microvascular caliber (VShis). Pearson correlation analysis was used to evaluate the correlation between VSImean, VSImax and VShis respectively. Mann-Whitney U test was used to compare VSImean, VSImax and VShis between grade Ⅱ and Ⅲ oligodendrogliomas. ROC analysis was performed to assess the effectiveness of VSImean, VSImax and VShis in grading oligodendrogliomas. Results Both VSImean and VSImax were strongly correlated with VShis (r=0.738, 0.705,P<0.05). For gradeⅡand Ⅲ oligodendrogliomas, VSImean were 38.93(17.96 to 81.18)μm and 91.49(36.94 to 144.68)μm, VSImax were 45.12(22.30 to 89.65)μm and 121.19(57.29 to 164.00)μm, VShis were 8.51(5.25 to 12.76)μm and 11.03(7.59 to 21.96)μm respectively. VSImean, VSImax, and VShis showed significant difference (Z=-3.505,-3.911, -2.729,P<0.05) between grade Ⅱ and Ⅲ oligodendrogliomas. ROC analysis revealed that the optimal cutoff value, sensitivity, specificity and AUC of VSImean was 52.58 μm, 90.91%, 92.31%, 0.923 respectively, 81.18μm, 90.91%, 100.00%, 0.972 for VSImax, and 9.01μm, 90.00%, 84.62%, 0.838 for VShis respectively. Conclusions Vessel size imaging derived VSI correlated well with histopathology. It could provide valuable information in the pre-operative grading of oligodendroglioma.

Objective To analyze the genetic difference of biological characters on germplasm resources of fenugreek(Trigonella foenumgraecum) and to study the genetic diversity of them.Methods Thirty-two fenugreek germplasm resources from Ningxia, other provinces in China,and abroad were used to investigate the biological characters on plant height,pod formation height,nodes per main stem,branches number,effective pod per plant and so on.The tested materials were planted in the farm of Ningxia University.The genetic diversity based on the phenotype was analyzed by Word′s minimum variance method.Results The variance analyses of ten biological characters were of significance or the most significance except pod length.The branches number and effective pod per plant possessed the largest coefficient of variance(CV). The pairwise Euclidean distance of the tested materials ranged from 1.11 to 9.49,averaged 4.01.Mean Euclidean distance of single tested material ranged from 2.94 to 6.54.The tested germplasm resources could be divided into three groups in D=6.86,which coincided with the district of collecting germplasm resources on the whole.Conclusion There is a little genetic difference in various fenugreek germplasm resources.Compared with Euclidean distance of germplasm resources from Ningxia,the Euclidean distance of most from abroad is far away from that of other provinces in China.

Objective To analyze the texture features of SPIO-enhanced MR imaging in rat models of hepatocellular carcinoma (HCC) and hepatocirrhosis with gray level co-occurrence matrix (GLCM). Methods HCC and hepatocirrhosis models were established in rats. SPIO-enhanced MR images were obtained. A total of 161 regions of interests (ROIs, 81 of HCC and 80 of hepatocirrhosis) were selected manually. Feature values as angular second moment, contrast, correlation, inverse difference moment, entropy, variance were extracted based on GLCM. The differences of feature values between two groups were statistically analyzed. Results In SPIO-enhanced MR images, hypointense signal changes were found in hepatocirrhosis, as well as hyperintensity in HCC nodules and intermixed intensity in larger HCC nodules. Correlation and entropy values of HCC group were higher than that of hepatocirrhosis group, while the angular second moment, contrast, inverse difference moment, and variance values were lower than hepatocirrhosis group. Conclusion The feature values based on GLCM could be used for the further computer aided diagnosis of SPIO-enhanced MR images in rat models of HCC and hepatocirrhosis.

Objective To investigate the applied value of abnormalities of fetus with oligohydramnios in mid-pregnancy by anmioinfusion. Methods Fifty women with oligohydramnios diagnosed by ultrasonograph were analysed retrospectively. During the procedure 60-300 ml saline solution at 37 ℃ were infused into the amniotic cavity,made prenatal diagnosis at the same time necessarily. And examined the women to know whether the fetal anomaly existed or not after the amnioinfusion by the ultrasound. Results There were 15 cases with fetal anomaly, 8 cases with genitotirinary anomaly(2 cases associated with multiple organs anomaly), 1 case with single umbilical artery, 4 cases with chromosomal abnormality (2 cases associated with fetal growth restriction), 2 cases with pulmonary hypolasia. There was no significant difference in dilivery outcome between others and 35 cases with normal pregnant women (P >0.05).
