OBJECTIVETo explore the regulation on 2-hour postprandial blood glucose (2h PBG) for patients with impaired glucose tolerance (IGT) in the intervention with electroacupuncture.

METHODSSixty cases of IGT were divided randomly into an electroacupuncture group and a blank control group, 30 cases in each one. In electroacupuncture group, electroacupuncture was applied to Shenshu (BL 23), Pishu (BL 20), Zusanli (ST 36) and Sanyinjiao (SP 6) in the intervention, lasting for 6 sessions. In blank control group, no any intervention was adopted. The levels of fasting blood-glucose (FBG), 2 h PBG with 75 g glucose and hemoglobin Alc (HbAlc) were observed before and after the intervention for the patients in electroacupuncture group, as well as in blank con trol group.

RESULTSThe total effective rate was 76.7% (23/30) in electroacupuncture group, which was superior to that of 16.7% (5/30) in blank control group (P < 0.01). 2h PBG [(7.08 +/- 0.74) mmol/L] and HbAlc [(5.74 +/- 0.35)%] were down-regulated significantly after the intervention with electroacupuncture of 6 sessions in electroacupuncture group. The therapeutic effects of it were superior remarkably to those [(8.93 +/- 1.87) mmol/L, (5.97 +/- 0.591)%] in blank control group, indicating statistical significant difference (P < 0.01, P < 0.05). But, there was no any impact for the patients with normal FBG.

CONCLUSIONElectroacupuncture may be the means to achieve the clinical effective intervention for the people with IGT and the approach in the prevention and treatment of diabetes at the early stage.

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 of glucose 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 (AUCI) 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/AUCI 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 (AUCI) 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 AUCI in the HT group changed slightly. A relative deficiency of insulin secretion or dysfunction of beta-cell of islet existed in IGT and DM of the hypertensive patients.

It is reported that patients with primary hyperparathyroidism(PHPT) have disturbances in carbohydrate metabolism: in particular, hyperinsulinemia and insulin resistance are characteristic early metabolic aberrations of this disease. However, it is not clear whether changes of insulin secretion or insulin sensitivity are observed in all patients with PHPT, including those with normal glucose tolerance. Also, it is not clear whether these changes are reversible after surgical correction of PHPT. In the present study, glucose tolerance and insulin secretion were evaluated in 2 symptomatic patients with PHPT during 100g oral glucose tolerance test before and after parathyroid adenoma removal. Comparing these patients before and after surgery, glucose tolerance was not significantly different. However, C-peptide and insulin secretion was low after surgical correction of PHPT compared to the preoperative situation. This observation suggests that insulin hypersecretion in patients with PHPT precedes glucose intolerance and this early disturbance is reversible after surgery.

OBJECTIVETo observe clinical curative effect of cake-separated moxibustion on impaired glucose regulation (IGR) and explore its action mechanism.

METHODSSixty cases were randomly divided into a simple lifestyle intervention group (control group) and a cake-separated moxibustion combined with lifestyle intervention group (observation group), 30 cases in each one. The control group was treated with lifestyle intervention. Based on lifestyle intervention, cake-separated moxibustion at Pishu (BL 20), Weishu (BL 21) and Yishu (EX-B 3) was applied to the observation group. Fast plasma glucose (FPG), two hours plasma glucose after oral glucose tolerance test (OGTT2hPG), fasting insulin (FINS), homa insulin resistance index (HOMA-IR), blood lipid, body mass index (BMI) and waist circumference (WC) were observed in the two groups before and after treatment.

RESULTSAfter treatment, the OGTT2hPG and FPG were both decreased significantly (both P<0.05) in the two groups, compared between the two groups, the differences of FPG [(0.41 +/- 0.42) mmol/L vs (0.05 +/- 0.08)mmol/L] and OGTT2hPG [(0.85 +/- 0.53)mmol/L vs (0.17 +/- 0.19)mmol/L] were both statistically significant. There were no significant changes in FINS, HOMA-IR, blood lipid, BMI and WC in the control group before and after treatment (all P>0.05), but FINS, HOMA-IR levels, triglycerides (TG), total cholest-erol (TC), low density lipoprotein (LDL-C), BMI and WC in the observation group were decreased obviously after treatment (all P<0.05), which had statistical differences between the two groups (all P<0.05).

CONCLUSIONThe cake-separated moxibustion combined with lifestyle intervention can obviously control blood glucose levels, improve insulin resistance and blood lipid levels, decrease BMI and WC.

The increasing risk of glucose intolerance and diabetes associated with aging is well established. However, it is difficult to determine whether changes in glucose metabolism result from biological aging itself or due to various environmental factors that occur during the aging process. Many epidemiologic studies have shown that plasma glucose levels after oral glucose tolerance test rise consecutively for every decade of age, but many of these studies also demonstrated the effects of environmental factors including obesity and exercise. In some studies, the development of insulin resistance and insulin secretion defects due to biological aging itself have also been identified as major etiologic factors of glucose intolerance. However, the rate of diabetes development due to these factors is expected to be very slow and largely preventable by addressing environmental risk factors.

Gestational diabetes mellitus (GDM) is an impaired fasting glucose condition during pregnancy. Adiponectin is a polypeptide hormone that is extensively released by adipocytes which regulates energy homeostasis and carbohydrate and lipid metabolism. In addition, adiponectin has antidiabetic and anti-inflammatory properties. The aim of our research was to study about the relationship of adiponectin levels to GDM and glucose intolerance. We selected 25 GDM women and 35 healthy pregnant subjects (18–46 years) who were screened between 24 and 28 weeks of gestation based on the result of oral glucose tolerance test (OGTT). We designed a case-control study and measured the concentrations of serum adiponectin and compared the concentrations between the groups. Serum adiponectin concentration was measured using enzyme-linked immunosorbent assay (ELISA). Sociodemographic data were collected by personal interview. Serum adiponectin concentrations were significantly lower in the subjects with GDM (5.10 ± 2.15 ng/mL vs. 7.86 ± 3.52 ng/mL, p = 0.001) than in healthy pregnant subjects. The mean concentration of fasting blood glucose was considerably lower in control subjects (86.9 ± 9.0 mg/dL vs. 175.9 ± 20.1 mg/dL, p < 0.001) in comparison to GDM subjects. Our findings showed that serum concentrations of adiponectin were significantly lower in gestational diabetic women and this may help to predict the risk of GDM.

PURPOSE:The incidence of glucose intolerance is increased in patients with Turner syndrome. Both noninsulin dependent diabetes mellitus and insulin dependent diabetes mellitus are increased. The purpose of this study was to investigate the impaired rate of carbohydrate metabolism in Turner syndrome after growth hormone treatment. METHODS:We investigated the incidence of carbohydrate intolerance and diabetes mellitus in 94 patients with Turner syndrome with NDDG and WHO criteria. The oral glucose tolerance test was performed in 78 patients. In 12 patients treated with growth hormone, the glucose tolerance test was performed before and after treatment. The insulin tolerance test was done in 20 patients. RESULTS:Only one patient had random plasma glucose level of more than 200 mg/dl. In results of the glucose tolerance test(n=78), 2 patients had glucose tolerance by NDDG criteria and 7 patients had it by WHO criteria. There was no change in glucose tolerance test results during growth hormone treatment. According to the results of the insulin tolerance test, we couldn't find any difference in insulin resistance between the growth hormone treatment group and the other treatments(oxandrolone, estrogen) group. CONCLUSION: The impaired rate of carbohydrate metabolism in Turner syndrome was much lower than in other reports. We observed that the impaired rate of carbohydrate metabolism did not increase after growth hormone treatment. However, the long-term effects in patients treated with growth hormone will be elucidated.

OBJECTIVEAbnormal glucose metabolism during pregnancy can result in significant adverse outcomes for newborns. This study was designed to investigate the effect of different degrees of impaired glucose tolerance on newborns.

METHODSGlucose challenge test (GCT) and oral glucose tolerance test (OGTT) were performed in pregnant women at 24-28 weeks of gestation. Based on the results of the two tests, their newborn infants were classified into five groups: gestational diabetes mellitus (GDM, n=182), gestational impaired oral glucose tolerance [GIGT, subdividing into GIGT 1 h (n=57) and GIGT 2-3 h groups (n=156)based on the occurrence time of abnormal blood glucose after glucose load], GCT abnormal but OGTT normal (only GCT abnormal, n=38) and normal glucose tolerance (control, n=1 025). The perinatal outcomes were compared among the five groups.

RESULTSThe incidences of macrosomia, large for gestational age (LGA), small for gestational age (SGA), neonatal hypoglycemia and premature birth in the GIGT (1 h) group were significantly higher than those in the control group, but similar to those in the GDM group. The incidences of macrosomia, SGA, neonatal hypoglycemia and premature birth in the GIGT (2-3 h) and the only GCT abnormal groups significantly decreased as compared with those in the GDM group, and similar to those in the control group. GIGT (1 h ) group showed higher incidence of neonatal hypoglycemia and premature birth than the GIGT (2-3 h) and the only GCT abnormal groups.

CONCLUSIONSDifferent degrees of maternal impaired glucose tolerance have different effects on newborns. As maternal GDM, maternal GIGT (1 h) may increase the risk of macrosomia, LGA, SGA, neonatal hypoglycemia and premature birth.
