Background A five-year follow-up study of intensive multifactorial intervention was undertaken to assess the changes of circulating serum amyloid A (SAA) levels and the incidence of atherosclerosis (AS) in patients with short-duration type 2 diabetes mellitus (T2DM) without macroangiopathy, and whether intensive multifactorial intervention could prevent or at least postpone the occurence of macroangiopathy. Methods Among 150 patients with short-duration T2DM, 75 were assigned to receive conventional outpatient treatment (conventional group) and the others underwent intensive multifactorial integrated therapy targeting hyperglycemia, hypertension, dyslipidemia and received aspirin simultaneously (intensive group). Results Plasma SAA levels were higher in diabetic patients than those in healthy control subjects, and decreased obviously after intensive multifactorial intervention. The levels of SAA were positively correlated with body mass index (BMI), waist hip ratio (WHR), triglyceride (TG), high sensitive C-reactive protein (hs-CRP) and common carotid intima-media thickness (CC-IMT). The standard-reaching rates of glycemia, blood pressure and lipidemia were significantly higher in intensive group than those of conventional group. The incidence of macroangiopathy decreased by 58.96% in intensive group compared with conventional group. Conclusions Intensive multifactorial intervention may significantly reduce the SAA levels and prevent the occurrence of AS in short-duration patients with T2DM. SAA might be one of the risk factors of T2DM combined with AS.  相似文献

Objective: To observe the therapeutic effect of Tang No.1 granule (糖1号方, T1G) in treating patients with impaired glucose tolerance (IGT). Methods: One hundred and forty patients with IGT and with Pi (脾)-Wei (胃) dampness-heat syndrome type were assigned randomly according to their visiting sequence into two equal groups. The control group received only general knowledge about IGT, but to the treated group, based on current knowledge available, T1G was given additionally for 6 months. Changes in related laboratory indexes, including fasting plasma glucose and insulin (FPG and FINS), plasma glucose 2 h after meal (2hPG), glycosylated hemoglobin (HbAlc), serum triglyceride (TG), low density lipoprotein cholesterol (LDL) and insulin resistance index (HOMA-IR), were observed. Results: The levels of FPG, 2hPG, HbAlc, FINS, TG and HOMA-IR were significantly decreased after treatment in the treated group, showing a significant difference compared to the control group (P〈0.01). Among them, HbAlc decreased from 7.08±1.41% to 6.56±1.29% in the treated group, while in the control group, it decreased from 7.02±1.37% to 6.93±1.31%. The level of LDL was also reduced in the treated group after treatment (P〈0.05). In the treated group, 13 out of 68 patients (19.12%) had their glucose tolerance reversed to normal, while in the control group, only 2/64 (3.1%) got it reverse; a comparison between the two groups in terms of reversion rate showed a significant difference (P〈0.01). No severe adverse reaction was found in the therapeutic course. Conclusions: T1G has good clinical effect as a treatment intervention for IGT, as it could improve glycometabolism, significantly depress the levels of post-prandial blood sugar and blood lipids, alleviate clinical symptoms of patients, and effectively cut-off and reverse the yielding and development of diabetes mellitus.  相似文献

The insulin sensitivity in hypertensive patients with normal glucose tolerance (NGT),impaired glucose tolerance (IGT) and type 2 diabetes mellitus (DM) and the insulin resistance (IR) under the disorder or grucose metabolism and hypertension were studied.by glucose tolerance test and insulin release test,insulin sensitivity index (ISI) and the ratio of area under glucose tolerance curve (AUCG) to area under insulin release curve (AUC1) were calculated and analyzed.The results showed that ISI was decreased to varying degrees in the patients with hypertension,the mildest in the group of NGT with hypertension,followed by the group of IGT without hypertension,the group of IGT with hypertension and DM(P=0).There was very significant difference in the ratio of AUCG/AUC1 between the hypertensive patients with NGT and controls (P=0).It was concluded that a significant IR existed during the development of IGT both in hypertension and nonhypertension.The increase of total insulin secretion (AUC1) was associated with nonhypertension simultaneously.IR of the hypertensive patients even existed in NGT and was worsened with the deterioration of glucose metabolism disorder,but the AUC1 in the HT group changed slightly.A relative deficiency of insulin secretion of dysfunction of β-cell of islet existed in IGT and DM of the hypertensive patients.  相似文献

Objective: To evaluate the long-term clinical effect of Tangyiping Granules(糖异平颗粒, TYP) on patients with impaired glucose tolerance(IGT) to achieve normal glucose tolerance(NGT) and hence preventing them from conversion to diabetes mellitus(DM). Methods: In total, 127 participants with IGT were randomly assigned to the control(63 cases, 3 lost to follow-up) and treatment groups(64 cases, 4 lost to follow-up) according to the random number table. The control group received lifestyle intervention alone, while the patients in the treatment group took orally 10 g of TYP twice daily in addition to lifestyle intervention for 12 weeks. The rates of patients achieving NGT or experiencing conversion to DM as main outcome measure were observed at 3, 12, and 24 months after TYP treatment. The secondary outcome measures included fasting plasma glucose(FPG), 2-h postprandial plasma glucose(2h PG), glycosylated hemoglobin(Hb A1c), fasting insulin(FINS), 2-h insulin(2hI NS), homeostatic model assessment of insulin resistance(HOMA-IR), blood lipid and patients' complains of Chinese medicine(CM) symptoms before and after treatment. Results: A higher proportion of the treatment group achieved NGT compared with the control group after 3-, 12- and 24-month follow-up(75.00% vs. 43.33%, 58.33% vs. 35.00%, 46.67% vs. 26.67%, respectively, P0.05). The IGT to DM conversion rate of the treatment group was significantly lower than that of the control group at the end of 24-month follow-up(16.67% vs. 31.67%, P0.05). Before treatment, FPG, 2h PG, Hb A1 c, FINS, 2h INS, HOMA-IR, triglyceride(TG), total cholesterol, low- and high-density lipoprotein cholesterol levels had no statistical difference between the two groups(P0.05). After treatment, the 2hP G, HbA 1c, HOMA-IR, and TG levels of the treatment group decreased significantly compared with those of the control group(P0.05). CM symptoms such as exhaustion, irritability, chest tightness and breathless, spontaneous sweating, constipation, and dark thick and greasy tongue were significantly improved in the treatment group as compared with the control group(P0.05). No severe adverse events occurred. Conclusion: TYP administered at the IGT stage with a disciplined lifestyle delayed IGT developing into type 2 DM.  相似文献

Objective: To probe glycemic excursions in type 2 diabetic patients whose hemoglobin A1c (HbA1c) was kept ≤6.0%. Methods: Totally 36 cases with type 2 diabetes (T2DM) with HbA1c≤6.0% and 30 cases with normal glucose tolerance (NGT) from December 2005 to December 2007 in our department were subjected prospectively. Continuous glucose monitoring system (CGMS) was employed to record their continuous blood glucose level for 3 d. The blood glucose profiles including the mean blood glucose (MBG), standard differentiation (SD), mean amplitude of glycemic excursions (MAGE) and absolute means of daily differences (MODD) were analyzed. Results: T2DM group had obviously postprandial hyperglycemia, in about 2 h after meal, especially after breakfast. Fifty-two hypoglycemic episodes occurred during the monitoring period in T2DM groups, of which 73.1% (38 episodes) were absence of symptomatic hypoglycemia with the lowest value of blood glucose only 2.0 mmol/L. And 20 episodes took place during the day hours, while 32 episodes observed during the night hours. Compared with NGT groups, SD, MAGE and MODD were all significantly higher in T2DM groups. MBG was significantly correlated with HbA1c in T2DM groups, but SD, MAGE, NGE and MODD were all independent of HbA1c. MAGE was independent of MODD. Conclusion: The amplitude of glycemic excursions is higher in normol-controlled T2DM groups than the NGT groups Thus ideally glycemic control is not only to make HbA1c reach standard, but also to lessen glycemic excursions and reduce hypoglycemia episodes.  相似文献

The function of CD4+CD25+ regulatory T lymphocytes (Treg) in patients with acute coronary syndrome (ACS) and the effects of atorvastatin were investigated. Forty-eight patients with ACS were randomly divided into two groups: group C receiving conventional therapy (n=24), and group C+A receiving conventional therapy+atorvastatin (10 mg/day, n=24). T lymphocytes from ACS patients (before and 2 weeks after the treatment) or 18 healthy subjects were separated and the flow cytometry was used to measure the percentage of Treg. The inhibitory ability of Treg on effector T cells was determined by mixed lymphocyte reaction (MLR). ELISA was used to measure the serum levels of cytokines (IL-10, TGF-β1 and IFN-γ) before and after treatment. The results showed that as compared with normal control group, Treg percentage was decreased significantly (P〈0.01), the inhibitory ability of Treg on the T lymphocytes proliferation was reduced (P〈0.01), IFN-γ levels were increased and IL-10 and TGF-β1 levels were lowered in ACS patients. After treatment with atorvastatin, Treg percentage and the inhibitory ability of Treg on T lymphocytes proliferation were significantly increased in ACS patients. Serum IFN-γ was decreased significantly, while IL-10 and TGF-β1 were elevated significantly as compared with the non-atorvastatin group. The number of Treg was positively correlated with serum TGF-β1, but negatively with serum IFN-γ and CRP. It was concluded that ACS was associated with decreased number and defected function of Treg, which may play an important role in initiating immune-inflammatory response in ACS. The inhibitory effects of atorvastatin on inflammation in ACS may be due to its beneficial effects on Treg and restoration of immune homeostasis.  相似文献

Objective To evaluate effects of rosiglitazone (RSG) on the expression of adiponectin in mature adipocytes at high levels of both testosterone (T) and insulin in vitro culture. Methods Mouse 3T3-L1 preadipocytes were induced to be mature adipocytes and used in this study. According to RSG concentrations, the cells added with T (10^-5 mol/L) and insulin (10^-4 mol/L) were divided into 4 groups: free-RSG group (0 mol/L RSG, FR-TI), low-dose group (10^-9 mol/L RSG, LR-TI), middle-dose group (lO-7mol/L RSG, MR-T1) and high-dose group (10^-6 mol/L RSG, HR-TI). Besides, the cells added with RSG without T and insulin were also divided into 4 groups: FR, LR, MR, and HR. These 8 groups were incubated for 42 h. Cell viability was determined by MTT assay. Expression of adiponectin was detected by Western blotting. Results The maximum viability in FR-TI group was observed at point of 42 h. The growth of the adipocytes was significantly inhibited in MR-TI group compared with FR-TI (P〈0.01). The level of adiponectin in MR-TI group was higher than that in LR- TI group (P〈0.01). However, with RSG increasing; HR-TI group showed the lowest level of adiponectin among three treatment groups (P〈0.01). In addition, adiponectin expression in MR-TI group was significantly higher than that in MR group (P〈0.01). Conclusion RSG could increase the expression of adiponectin in 3T3-L1 adipocytes under high levels of both T and insulin, but it acts in a narrow concentration range.  相似文献

This study was aimed to examine the effect of ovariectomy on visceral fat, serum adi- ponectin levels and lipid profile. Forty-five female Sprague DawIey rats were divided into three groups (n=15 each): ovariectomized group (OVX), ovariectomized plus estrogen-treated group (OVX+E2), and sham-operated group (SHAM). Body weight, abdominal adipose tissues, serum adiponectin and lipid profile were measured and compared among the groups after three-month feeding post-surgery. Signifi- cant increases in body weight and visceral fat were found in ovariectomized rats when compared with sham-operated ones and significant increases were also observed in serum adiponectin, triglyceride and very low density lipoprotein cholesterol levels in ovariectomized rats. Body weight, visceral fat and se- rum adiponectin levels were profoundly reduced in OVX+E2 group as compared with OVX group. It was concluded that ovarian hormone deficiency induced by ovariectomy leads to significant increases in body weight and visceral fat, along with increased serum adiponectin, triglyceride and very low density lipoprotein cholesterol levels in rats. Attenuation in these changes can be achieved by estrogen supple- mentation.  相似文献

Association of serum uric acid with different levels of glucose   总被引:3,自引:0,他引:3  
Background  Previous studies have demonstrated that serum uric acid (UA) is an independent predictor of incident type 2 diabetes mellitus (T2DM) in general populations. This study aimed to investigate specific characteristics of UA and its relationship between UA and blood glucose and other risk factors in the Chinese population.
Methods  A total of 946 subjects were included in this study. UA, glucose, insulin, fractional excretion of UA (FEua), creatinine clearance rate (Ccr), hemoglobin A1c (HbA1c), fructosamine (FA), blood pressure and lipids were studied and also reexamined after the patients underwent two weeks of combined therapeutics.
Results  UA levels were the highest in subjects with impaired glucose regulation (IGR), followed by subjects with normoglycemia (NGT) and finally by subjects with T2DM. The level of the 2-hour postprandial insulin and the area under the curve for insulin (AUCins) showed a similar tendency. The UA levels initially increased with increasing fasting blood glucose (FBG) and postprandial blood glucose (PPBG) levels, up to 7 mmol/L and 10 mmol/L, respectively, and thereafter decreased at higher FBG and PPBG levels. Compared with subjects in the lower serum UA quartile, subjects in the upper quartile of serum UA levels had higher weights, triglyceride levels, and creatinine levels as well as lower Ccr and FEua levels. Compared with women’s group, UA levels were higher, and FEua levels were lower in men’s group. Sex, body mass index (BMI), mean arterial blood pressure (MAP), serum triglycerides (TG), FA and Ccr were independent correlation factors of UA. UA decreased and FEua increased after the patients underwent a combined treatment.
Conclusions  UA increased initially and then decreased as glucose levels increased from NGT to IGR and T2DM. Compared with NGT and T2DM, IGR subjects had higher SUA levels, which related to its high levels of insulin. Under T2DM, male gender, BMI, MAP, Ccr, TG and FA are independent correlation factors of UA. Glucose-lowering, antihypertensive, lipemia-regulating combined treatments were of advantage to decline of SUA of T2DM.

To investigate the value of ultrasound speckle tracking imaging (STI) in the assessment of the short-axis and long-axis systolic function of the left ventricle (LV) in patients with type 2 diabetes mellitus (DM), 100 subjects with normal ejection fraction were studied, including 41 patients with DM only (DM group), 22 patients with both DM and left ventricular hypertrophy (DH group), and 37 healthy subjects (control group). Left ventricle systolic function in the long axis defined as longitudinal strain, and that in the short axis defined as radial strain, apical and basal LV rotations, and LV twist were assessed respectively. The results showed that average peak strain in the long axis at basal, middle and apical levels, and global peak strain were significantly decreased in the patient groups when compared with the control group (P〈0.001 for each). The parameters in DH group were significantly lower than those in DM group (P〈0.01 for each). There were no significant differences in average radial peak strain in the short axis at different levels, and global peak strain among the three groups (P〉0.05). Apical and basal LV rotations, and LV twist were greater in the patient groups than in the control group (P〈0.01 for each). Basal LV rotation and LV twist were greater in DH group than those in DM group (P〈0.01). It was concluded that STI may be used to identify early abnormalities in patients with type 2 DM that have normal left ventricular systolic function.  相似文献

目的探讨血清脂连蛋白与超敏C反应蛋白(hs-CRP)水平在2型糖尿病(T2DM)合并冠心病(CHD)诊断中的价值。方法选择2011年2月至2013年2月在新乐市医院门诊就诊或住院治疗的96例T2DM作为研究对象,其中48例合并CHD的患者作为T2DM-CHD组,48例单纯T2DM患者为T2DM组,另外选取同期在本院进行健康体检者50例作为对照组,测量并比较研究对象血清脂连蛋白、hs-CRP、空腹血糖(FBG)的水平。结果三组血清脂连蛋白、hs-CRP、FBG水平的比较,差异有统计学意义(F=3.681、4.256、3.470,P=0.016、0.007、0.034);其中T2DM-CHD组和T2DM组的脂连蛋白水平均低于对照组(q=7.603、4.028,P<0.05),hs-CRP和FBG水平显著高于对照组(P<0.05);T2DM组患者血清脂连蛋白水平显著高于T2DM-CHD组(q=3.752,P<0.05),hs-CRP、FBG水平显著低于T2DM-CHD(q=5.627、3.217,P<0.05),而且血清脂连蛋白水平与hs-CRP水平呈显著负相关(r=-0.692,P<0.05)。结论 T2DM患者血清中脂连蛋白、hs-CRP的水平能够反映CHD的严重程度,其对于T2DM并发CHD患者的诊断和治疗具有重要的临床价值。  相似文献
