Objective To study the predictive value of islet cell antibody (ICA),64KD protein antibody(64KDAb) and insulin auto-antibody (IAA) in the first-degree relatives of type 1 diabetics. Methods The determination of islet autoantibody distribution in type 1 diabetes patients,first-degree relatives without diabetes and normal individuals was made. Results The results revealed that ICA and 64KDAb positive rate in type I diabetes patients and their first-degree relatives was significantly higher than normal individuals. The positive rate of 64KDAb is higher than that of ICA and IAA. Conclusion These results suggest that 64KDAb's sensitivity is higher than ICA and IAA's,so 64KDAb is more valuable as the marker of predicting type 1 diabetes. The combined determination of ICA, 64KDAb and IAA might improve the value for predicting diabetes.

The peptides molecular compositions and the amino acids component of the enzymolyzed protein of anchovy soluble peptides hydrolysed by pepsin and trypsin were assayed and determined by gel HPLC and amino acid analytical instrument.The molecular weight of the peptides is less than 7400, of which 1.74 percent is a large peptide chain with composition of 52~58 amino acids and 6600~7400 molecular weight,29.75 percent is a middle large peptide with 20~41 amino acids and 2500~5300 molecular weight , and 50 percent is a oligo-peptide with 2~10 amino acids and less than 1000 molecular weight. The proportion of total nitrogen to rree amino acid nitrogen is 25.9:1 in the hydrolysates. 96 pecent of amino acid exists in form of peptides and 4 percent are free amino acids. The con tent of whole amino acids accounts for 73.98 percent soluble peptides, and the essential amino acid is 32.39 percent or 43.78 percent of the whole amino acids .Comparing whth FAO/WHO , the phenylalanine expresses in the first limited amino acid with the amino acid score of 61. Based on the analysis results, the balance of amino acid composition pf anchovy loluble peptides and the physiological function of loigo-peptide in an animal organism were explored.

Objective To investigate the clinical value of homocysteine (Hcy) ,cystatin C (Cys C) and high‐sensitivity C‐reactive protein (hs‐CRP) in atherosclerosis (AS) .Methods Totally 100 cases of newly diagnosed patients of AS were choosed as the ob‐servation group ,36 cases condition improved markedly of AS after treatment as the treatment group ,and 120 cases of normal medi‐cal groups as the control group ,the Hcy ,Cys C and hs‐CRP in all subjects were detected respectively .Results Hcy ,Cys C and hs‐CRP levels of observation group were significantly higher than those of normal groups ,and the difference was statistically signifi‐cant (P< 0 .05) .While the Cys C and hs‐CRP levels of treatment group were significantly lower than the those of observation group ,the difference was also statistically significant (P< 0 .05) .Conclusion The detection of Serum Hcy ,Cys C and hs‐CRP might be help to the diagnosis ,treatment evaluation and prognosis of AS .

Objective To investigate the C-reactive protein (CRP) concentrations in the pathogenesis of type 2 diabetes mellitus (DM) and its macrovascular complications. Methods Serum CRP levels were assayed by ELISA, which were determined in type 2 DM patients with or without macrovascular complication (88 and 64 cases respectively), non-DM patients presenting with macrovascular disease (72 cases), as well as impaired fasting glucose (IFG) (62 cases) or impaired glucose tolerance (IGT) (70 cases) patients and normal controls (80 subjects). Results In general, CRP levels in IGT patients, type 2 DM patients and non-DM patients presenting with macrovascular disease were higher than those of normal controls (P

Objective:To study the relationship between HLA-DRB1 gene polymorphisms and macrovascular complication of type 2 diabetics. Methods:HLA-DRB1 alleles in 88 cases of type 2 diabetics, including 52 ones without complication and 36 ones with macrovascular complication, were examined by PCR-SSP. Results:There were at least 11 HLA-DRB1 alleles in type 2 diabetics. The HLA-DRB1 *03 and HLA-DRB1 *09012 gene frequencies of type 2 diabetics with macrovascular complication were significant higher than those without complication.Conclusion:HLA-DRB1 *03 and HLA-DRB1 *09012 alleles or their linkage disequilibrium genes may enhance the risk of the development of type 2 diabetes macrovascular complication.

A cross-sectional study was conducted in Heilongjiang in a representative sample of 2 875Chinese adults aged from 20 to 74 years. Questionnaire was conducted. Their height, weight, waist circumference,blood pressure, blood glucose, serum insulin, lipids, and other indexes were determined. The criterion of International Diabetes Federation was applied for metabolic syndrome (MS) diagnosis. The results showed that the preliminary prevalence rate of MS was 19.34% and the age-adjusted prevalence rate of MS was 21.92% ( male 20.41% , female 23.11% ). The prevalence rate of MS increased with the age. The prevalence rate in the urban area was higher than that in the town and rural area ( both P < 0.05 ). The result of multiple factor logistic regression analysis showed that body fat content, insulin resistance, age, residential difference, drinking habit,daily staple food quantity, urine albumin, education, family history of obesity, and gender were related with MS.

OBJECTIVE:To observe the bleeding,therapeutic efficacy and ADR of patients with acute cerebral infarction (ACI) treated by alteplase intravenous thrombolysis. METHODS:140 ACI patients were randomly divided into group A and B with 70 cases in each group. Group A was give alteplase 0.6 mg/kg for intravenous thrombolytic therapy,and group B was given al-teplase 0.9 mg/kg for intravenous thrombolytic therapy. The bleeding after thrombolysis,bleeding time,therapeutic efficacy and ADR were compared between 2 groups. RESULTS:The incidence of Subcutaneous ecchymosis,gingival bleeding,bleeding of di-gestive tract and intracranial hemorrhage of group A were 4.29%,2.86%,2.86% and 2.86%;those of group B were 14.29%, 12.86%,11.43% and 11.43%;the bleeding time of those symptomsin 2 groups were(6.04±0.75)and(7.22±0.56)h、(24.63± 10.24)and(35.22±9.87)min、(3.04±0.11)and(4.08±0.25)h、(3.12±0.48)和(4.53±0.66)h respectirely,with statistical signifi-cance(P<0.05). There was no statistical significance in therapeutic efficacy and ADR between 2 groups after treatment(P>0.05). CONCLUSIONS:The bleeding should be monitored strictly when ACI patients receive alteplase intravenous thrombolysis,and low-dose alteplase thrombolysis can ultimately reduce the incidence of bleeding.

Objective To study the accuracy of real-time continuous monitoring system (RT-CGMS) at different stages and its association with glucose excursion. Methods Totally 33 patients with type 1 diabetes or type 2diabetes were under surveillance of RT-CGMS for 5 d. Capillary glucose values were measured 7 times daily.Correlation coefficient, error grid analysis (EGA), and Bland-Altman analysis methods were used to assess the correlation, accuracy and agreement of RT-CGMS at different stages and in general level; The mean amplitude of glucose excursion (MAGE) and the frequency of glucose excursion ( FGE ) were also calculated. Results ( 1 ) The correlation coefficient of RT-CGMS with capillary glucose values at fasting, postprandial stages, and in general level were 0.94,0.92, and 0.93 respectively( P＜0.01 ). (2) EGA showed that 98.82%, 98.39%, and 98.64% of the results fell in the A and B zones and 1. 18%, 1.61%, and 1.36% fell in the D zone respectively at fasting,postprandial stages, and in general level. There is no result fell in C and E zones. ( 3 ) The agreement analysis showed that RT-CGMS readings were in close agreement with capillary glucose values at fasting, postprandial periods, and in general level. (4)The MAGE at fasting, postprandial periods, and in general level were (3.57±2.66), (4.07±3.09), and (4. 02 ±3.04) mmol/L (P＞0. 05), (0±0. 5), (3± 1), and( 1 ±3) d for FGE (P＜0. 01 ).Conclusion RT-CGMS at fasting stage has higher accuracy than postprandial stage and general level, FGE at fasting stage is higher than postprandial stage and general level.
