Microalbuminuria is regarded as a reflection of increased capillary permeability associated with the systemic inflammatory response syndrome. It is obversed that many medical diseases such as diabetes,kidney disease and cardiovascular disease may result in microalbuminuria and reported microalbuminuria with correlation of the prognosis of the serious patients. This article reviews ,microalbuminuria with correlation of the prognosis of the serious patients, the value of predicting illness severity in the serious patients.

AIM and METHODS: To investigate the role of angiotensin Ⅱ recepters(ATRs) in overload pressure-induced left ventricular hypertrophy. The rat abdominal aortic constraction model was adopted. At 10th week after operating, angiotensin Ⅱ in myocardium was measured by radioimmunoassay,tissue ATRs and its subtype were analysed by radioligand binding assay. RESULTS: The AngⅡ content in the operated group was significantly higher than that of the control group, LVMI was positively correlated with AngⅡ(r=0.8066,P

Objective To investigate the role of angiotensin Ⅱ receptors in metabolism of m yocardial collagen. 　Methods The collagen volume fraction(CVF), perivascular circumferential area(PVCA), hydroproline concentration(HC), ratio o f collagen type Ⅰto type Ⅲ(Ⅰ/Ⅲ),angiotensin Ⅱ(AngⅡ) content and the maximal binding capaci ty (Bmax) of ATRs were studied. The methods of radioimmunoassay(RIA),biochemistry assay, and pathological examin ation were used. 　Results Ventricular myocardial CVF, PVCA, HC, Ⅰ/Ⅲ, AngⅡ and B max of ATRs in WKY rats were significantly higher than those in sham -operation(SO)(P<0.05 or P<0.01),suggesting the collagen was abnormal ly accumulated in rats heart muscles. AngⅡ was positivily correlated with HC(r1=0.9045, P<0.01). After treament of Irbesartan, All above parameter were reduced significantly(P<0.05 or P<0.01), abnormally accumulated collagen was disap peared. While after treament of CGP42112A,an ATR2 antagonist, Bmax of ATRs was markedly decreased(P<0 .01), but CVF, PVCA, HC,Ⅰ/Ⅲ, AngⅡ showed little changes(P >0.05). 　Conclusion Obvious hyperplasia of myocardial collagens and remode ling of collagen network occurred after pressure overload. Local produced AngⅡ involves in the process,it's effects is mainly mediated by angiotensin Ⅱ 1 type receptor(ATR1)

[Objective] To investigate the clinical characteristics and risk factors of lower-extremity arterial disease in the patients with newly diagnosed type 2 diabetes mellitus combined with nonalcoholic fatty liver disease (NAFLD). [Methods] One hundred fifty-one patients were investigated respectively. The patients were divided into two groups (NAFLD-Group and non-NAFLD group) by liver ultrasonography and disease history, then their clinical data were collected and compared in order to find the differences of biochemical indicators and the morbidity of lower-extremity arterial disease between two groups. [Results] Ninety-two cases (60.93%) were complicated with NAFLD. NAFLD group had higher levels of fast insulin and C peptide level, postprandial insulin and C peptide level, uric acid, body mass index (BMI), homeostasis model assessment (HOMA-IR) and lower level of high-density lipoprotein cholesterol and insulin sensitive index than those of without NAFLD (P<0.05). One hundred and one cases(66.89%) were complicated with lower-extremity arterial disease. The morbidity of lower-extremity arterial diseases was higher in NAFLD group than that of without NAFLD group (75% vs. 54.24%, P<0.01). [Conclusion] Both lower-extremity arterial disease and NAFLD are common complicated with type 2 diabetes. The morbidity of lower-extremity arterial diseases was higher in NAFLD group than that of without NAFLD group.

Objective: To study the relationship between C-reactive protein (CRP) gene polymorphisms and the risk of chronic peri-odontitis and severe chronic periodontitis (CP) with type2 diabetes to confirm the effect of genetic factor in chronic periodontitis and chronic periodontitis with type2 diabetes. Methods; DNA was extracted by Chelex-100 from buccal swabs of patients who suffered from chronic periodontitis or chronic periodontitis with type2 diabetes and patients with healthy periodontium. PCR-RFLP was used to test the CRP genotype distribution. The correlationship between the incidence of chronic periodontitis and chronic periodontitis with type2 diabetes and CRP gene polymorphism was analyzed statistically. Results; There was no statistical difference in the distribution of CPR +1059 genotype and allele frequency between experiment group and control group (X~2 = 0. 223, P=0.994). The genotype and allele frequency distribution were in line with Hardy-Weinberg equilibrium. Conclusion; There is no correlation between CRP + 1059G/C single nucleotide polymorphisms and the susceptibility of chronic periodontitis as well as chronic periodontitis with type2 diabetes.

Objective To investigate the relationship between dyslipidemia,obesity,insulin resistance (IR)and various degrees of non.alcoholic fatty liver disease(NAFLD)in patients with type 2 diabetes mellitus (T2DM), and the risk factors of NAFLD.Methods Two hundred and sixty-eight patients were divided into three groups(non-NAFLD group,mild NAFLD group,moderate and severe NAFLD group)by liver ultrasonography.Body height(H),weight(W),waist circumference(WC),hip circumference(H)were measured.The levels of fasting blood glucose (FBG),glycosylated hemoglobin A_1c(GHbA_1C),serum total cholesterol(TC),serunl high density lipoprotein(HDL-C),serum low density lipoprotein(LDL-C),serum triglyceride (TG),alanine aminotransferase (ALT)and fasting serum insulin(FINS)were measured.Body mass index(BMI),the waist to hip ratio(WHR)and insulin resistance index(HOMA-IR)were calculated.Unconditional logistic regression model was used to test for the risk factors of NAFLD.Results BMI、WC、WHR、HNS、HOMA.IR、TC、LDL-C、TG and ALT in NAFLD group were significantly higher than those in non-NAFLD group (P<0.05).The levels of BMI、WC、WHR、HNS、HOMA-IR、 TG and ALT increased significantly in moderate and severe NAFLD group compared with mild NAFLD group(P<0.05).TG、WHR and HOMA.IR were the risk factors of NAFLD(P<0.05,OR=2.394,3.273,5.256).Conclusions NAFLD in patients with T2DM had remarkable dyslipidemia,overweight,central obesity and insulin resistance.TG、WHR and HOMA.IR were risk factors of NAFLD.

Objective To compare the excursion of blood glucose (BG) in the type 2 diabetes mellitus treated with oral antidiabetic drugs (OADs) plus glargine or human isophane insulin (HII). Methods A 1 : 1 randomization schedule assigned 30 type 2 diabetics inadequately controlled on OADs (fasting BG>9.0 mmol/L and HbA1C > 8.5%) to 2 groups additionally treated with glargine or HII. The insulin dose was titrated to achieve fasting capillary BG<6.0 mmol/L. Montoring BG with continuous glucose monitoring system, then the standard deviation of BG (SDBG), maximal excursion of BG (LAGE) and coefficient of variation (CV) of fasting plasma glucose (FPG) were calculated. Results SDBG (1.49±0.35 vs 1.73±0.46), LAGE (3.23±0.76 vs 3.73± 1.00) and CV-FPG (17.26±2.24 vs 20.33±3.21) were lower in glargine group than those in HII group (P< 0.05). No difference could be found in hypoglycaemia between two groups. Conclusion OADs plus glargine could make blood glucose more stable than OADs plus HII without increasing the incidence of hypoglycaemia.

Objective To study the effects of sulodexide on islet B-cell function in streptozocin induced di-abetic rats. Methods Sprague-Dawley(SD) rats were randomly divided into normal control group (group C), dia-betic group without treatment(group D), and suledexide treatment group(group S), a single dose of streptozotocin were abdominally injected to establish the diabetic rat models. Each animal in sulodexide treated group was addition-ally fed with sulodexide of 10 mg/(kg·d) for 12 weeks,while the remained group (group C and D) were given normal water in the same period. After 12 weeks of treatment, fasting plasma glucose(FPG),fasting plasma insulin (FINS), activated partial thromboplastin time (APTT), prothrombin time (PT), thrombin time (TT), triglyceride (TG), Low-density lipoprotein cholesterol (LDL-C), serum creatinine rates (SCr) and alanine aminotransferase (ALT) were measured. Insulin sensitivity index(ISI) and insulin resistant index (HOMA-IR) were calculated. Results After 12 weeks, the levels of TG, LDL-C and ALT had no significant difference between group D and group S, but were higher than those in group C (P <0.05);There were no significant difference of SCr levels among the three groups. Compared with the group C, APTT, PT, TT and ISI in group D and S were significantly decreased, HOMA-IR were significantly increased (P < 0.05). APTT, PT, TT and ISI in group S had significantly increased compared with that in group D, HOMA-IR was significantly decreased in group S compared with that in group D (P < 0.01). Conclusions Sulodexide can reduce insulin resistant, improve hypercoagulability and insulin sensitiv-ity in streptozocin induced diabetic rats. The effects to blood lipid, liver and renal functions in diabetic rats are not obvious.

BACKGROUND:A variety of factors contribute to biliary injury that is difficult to be repaired. Stent implantation is extensively used for bile duct injury, but either scaffolds made by metal or plastics can lead to certain adverse reactions. OBJECTIVE:To explore the biological characteristics of a novel biodegradable scaffold and its repair effects on bile duct injury. METHODS:The biological characteristics of the novel biodegradable scaffold were detected by fresh bile, and its degradation was observed at different time points. Thirty Bama mini pigs were included and were randomly divided into observation group (n=15) and control group (n=15). After bile duct injury models were prepared, the control group was subjected to the bile duct interrupted suture, while the observation group was subjected to the novel biodegradable scaffold combined with omentum majus. The biological properties of the scaffolds were observed. Hepatic enzymes and serum total bilirubin levels were detected, as wel as hematoxylin-eosin staining, Masson staining and immunohistochemistry detection ofα-smooth muscle actin were performed. RESULTS AND CONCLUSION:Before and 1, 3 and 6 months after surgery, hepatic enzymes and total bilirubin of two groups were detected, and neither intra-group nor intergroup comparisons had significant differences (P>0.05). Hematoxylin-eosin staining and Masson staining revealed that inflammatory reactions and fiber hyperplasia at the anastomotic site in the observation group were lighter than those in the control group at different time points after surgery. Theα-smooth muscle actin-positive scores in both two groups were in a rise at 1 and 3 months after surgery, and peaked at the 3rd month, and then began to decline. Moreover, theα-smooth muscle actin-positive scores in the observation group were significantly lower than those in the control group at 3 and 6 months after surgery (P<0.05). These results show that the novel biodegradable scaffold has good biological characteristics and can obtain ideal repair effects in the bile duct injury.

Hepatolenticular degeneration was one of the rare several genetic metabolic diseases in clinic that could be cured by liver transplantation method, developing slowly and being irreversible. Metabolic disorders of copper lead to abnormal copper accumulation in various of tissues and organs. So that, the disease′s clinical manifestations were lacking in specificity and many patients missed the best opportunity of drug treatment. With the maturity of technologies and innovation of theory of liver transplantation, there were more and more methods that will be applied to personalized treatment. In this paper, a review of the research progress in the treatment of hepatolenticular degeneration with liver transplantation was made with reference to the relevant literature at home and abroad.
