1. Assessment of long-term glycaemic control in diabetic patients attending Port Moresby General Hospital
Papua New Guinea medical journal 1995;38(1):16-19
Good glycaemic control is important in preventing the acute and long-term complications of diabetes mellitus. We assessed long-term glycaemic control using glycosylated haemoglobins in 83 diabetic patients, of mean age 47 years and of mean known duration 4.5 years, attending Port Moresby General Hospital over a one-year period. Significant improvement in glycaemic control was observed in only 11 (13%) of the patients. Glycaemic control worsened in 13 (16%) and no change was observed in the remainder (71%). Mean glycosylated haemoglobin and fasting plasma glucose levels were similar at the beginning and end of the study period. Over a one-year period 53 patients (64%) exhibited poor control with mean glycosylated haemoglobin levels exceeding 10%. Among the 19 newly diagnosed diabetic patients (23% of the total) glycaemic control improved in only 2 (11%). Glycaemic control was not influenced by sex, treatment, obesity or duration of diabetes. The demonstration of poor metabolic control in the majority of patients suggests that urgent measures are needed to reevaluate the management of diabetic patients, particularly with respect to education and diet. This may improve the poor survival rates reported in diabetic patients from Papua New Guinea.

PURPOSE: Exercise is frequently recommended in the management of diabetes mellitus(DM) and can improve blood control by increasing insulin sensitivity and psychological benefits. Exercise can result in good glycemic control in type 2 DM, when combined with diet and drug therapy. However, in type 1 DM, the expected improvement in glycemic control with exercise have not been clearly established. Effects of exercise on glycemic control in patients with type 1 DM were investigated. METHODS: 20 patients with of type 1 DM, who were no retinopathy, neuropathy, nephropathy and cardiac disorders, were enrolled and exercised for 30min. with 50% of individualized maximum VO2. Blood sugar concentration were measured before, immediate and 15min after exercise. The results were evaluated with HbA1c, C-peptide and DM duration. RESULTS: Blood sugar concentration were significantly decreased from pre-exercise 198+/-9.7mg/dL to immediate 145+/-7.1mg/dL and at 15min. Post-exercise 134+/-4.0mg/dL(P<0.05). In case with HbA1c<10%, there was significantly decreased in blood sugar level from pre-exercise 176+/-9.7mg/dL to immediate 123+/-63.2mg/dL and at 15min post-exercise 113+/-1.9mg/dL(P<0.05). In case with HbA1c>10% there was also significantly decreased in blood sugar levels 222+/-64.7mg/dL, 169+/-6.1mg/dL, 157+/-1.2mg/dL respectively(P<0.05). Group with moderate decreased blood sugar(40-99mg/dL) was 8 patients(42.1%), group with mild decreased blood sugar(<40mg/dL) was 7 patients(36.8%) and group with decreased more than 100mg/dL was 4 patients(21.5%). There was no correlation in degree of decreased blood sugar concentration among HbA1c, C-peptide, DM duration. CONCLUSION: Proper exercise in type 1 diabetic children can decrease blood sugar level significantly and make good glycemic control and can decrease DM microvascular complications in addition to motivating physically active lifestyle.

Diabetes mellitus is common in our increasingly affluent and ageing population. Although it is an old friend of practising family physicians, there is a need to be familiar with and up to date about the disease. As patients become more informed and receptive to current medical information, family physicians also need to stay current. This article highlights the evidences that have shaped our current treatment targets for type 2 diabetes mellitus.

4.Glucose metabolism modeling of diabetes patients with different intensities of aerobic exercise: an in silico study.
Journal of Biomedical Engineering 2019;36(2):274-280
Exercise is vital for diabetics to improve their blood glucose level. However, the quantitative relationship between exercise modes (including types, intensity, time, etc.) and the blood glucose is still not clear. In order to answer these questions, this paper established a blood glucose metabolic model based on ordinary differential equation method. Furthermore, a silico method was adopted to study the effects of different aerobic exercise intensities (light, moderate and vigorous) on blood glucose and optimal strategies of insulin infusion for type 1 diabetes mellitus (T1DM) and type 2 diabetes mellitus (T2DM). Additionally, the universality of proposed model and insulin infusion strategies was verified based on 1 000 virtual diabetes patients' simulation. The experimental results showed that: (1) Vigorous-intensity aerobic exercise may result in hypoglycemia (< 3.89 mmol/L), which was so harmful to health that diabetics should avoid. Compared with moderate-intensity exercise, the light-intensity aerobic exercise intuitively lowered blood glucose slowly and caused a relative long high-blood-glucose (> 6.11 mmol/L) period, however, its overall blood glucose risk index (BGRI) was lower. (2) Insulin dosage of the optimized strategies decreased by 50% and 84% for T1DM and T2DM when they did moderate intensity exercise. As for light intensity exercise, the dosage of insulin was almost the same as they didn't do exercise, but BGRI decreased significantly. (3) The simulations of 1 000 virtual diabetic patients manifested that the proposed model and the insulin infusion strategies had good universality. The results of this study can not only help to improve the quantitative understanding about the effects of aerobic exercise on blood glucose of diabetic patients, but also contribute to the regulation and management of blood glucose in exercise mode.

OBJECTIVETo observe the effect of Jianpi Wenshen Decoction (JWD) on serum gastrin, plasma motilin and somatostatin in patients of diabetic diarrhea (DD).
METHODSPatients with DD were randomly divided into two groups, the JWD group and the control group treated with Loperamide (LPA). Besides, a normal control group was set up. Changes of serum gastrin, plasma motilin and somatostatin were observed.
RESULTSBefore treatment, the levels of gastrin and motilin in both groups were higher and somatostatin lower than those in the normal control group. After 1 month treatment, levels of the three indices were restored in both group approaching the normal range with insignificance as compared with those in the normal control group (P > 0.05). Level of plasma motilin and serum gastrin showed an increasing trend along with the therapeutic effect elevation, while level of somatostatin showed a decreasing trend.
CONCLUSIONJWD could promote the recovery of the impaired function of vegetative nerve system in DD patients. At the same time, serum gastrin, plasma motilin and somatostatin may be taken as the indexes for evaluating the efficacy in treating DD.

7.Latent autoimmune diabetes in adults: an update.
Acta Academiae Medicinae Sinicae 2003;25(5):630-634
Latent autoimmune diabetes in adults (LADA), presenting with a similar phenotype of type 2 diabetes at early stage, belongs to the slowly progressive subtype of autoimmune type 1 diabetes. LADA differs from classic juvenile-onset type 1 diabetes in which its autoimmune destructive process of islet beta-cells is much slower, so LADA may serve as a human model of autoimmune type 1 diabetes. Although no international standardized criteria for the diagnosis of LADA has been established, it should be noted that LADA has some specific features in clinical characteristics, susceptible genotypes, cellular and humoral immune markers, as well as islet pathology. Presence of islet autoantibodies is necessary for the diagnosis of LADA. Early insulin intervention may preserve residual islet beta-cell function in LADA. The different pathological manifestations of LADA with different autoantibody titers can help throw light on the autoimmune process, laying foundation of prevention or even cure of type 1 diabetes.

BACKGROUNDSubcutaneous absorption is accelerated by the monomeric conformation of insulin Aspart, which provides good glycemic control with a lower risk of hypoglycemia and less body weight increase. In the present study we investigated the efficacy and safety of a rapid-acting human insulin analogue (insulin Aspart) delivered with continuous subcutaneous insulin infusion (CSII) into Chinese diabetic patients.
METHODSA total of 21 patients with type 1 or type 2 diabetes were recruited for the 2-way cross-over, open-labeled trial, and then randomized to Group A (n = 10, treated with insulin Aspart) or Group B (n = 11, treated with Novolin R). Insulin Aspart and Novolin R were administered by CSII. Capillary glucose concentrations were measured at 8 time points, pre-prandial and postprandial, bedtime (10 pm), midnight (2 am) every day during the treatment.
RESULTSThe average capillary glucose profiles for the day were much better controlled in Group A than in Group B (P < 0.01). The blood glucose levels were particularly better controlled in Group A than in Group B at pre-breakfast ((6.72 +/- 1.24) mmol/L vs (7.84 +/- 1.58) mmol/L, P = 0.014), post-breakfast ((8.96 +/- 2.41) mmol/L vs (11.70 +/- 3.11) mmol/L, P = 0.0028), post-supper ((8.15 +/- 2.10) mmol/L vs (10.07 +/- 2.36) mmol/L, P = 0.008), bed time ((7.73 +/- 1.72) mmol/L vs (9.39 +/- 2.05) mmol/L, P = 0.007) and midnight ((6.32 +/- 1.16) mmol/L vs (7.48 +/- 1.36) mmol/L, P = 0.0049). There was no significant difference in the frequency of hypoglycemic episodes between the two groups.
CONCLUSIONInsulin Aspart results in better control of blood glucose levels than regular human insulin (Novolin R) in diabetic patients during delivery by CSII.

OBJECTIVETo evaluate islet beta cell response to intravenous glucagon (a non-glucose secretagogue) stimulation in diabetes mellitus.
METHODSNineteen patients with type 1 diabetes (T1D) and 131 patients with type 2 diabetes (T2D) were recruited in this study. T2D patients were divided into two groups according to therapy: 36 cases treated with insulin and 95 cases treated with diet or oral therapy. The serum C-peptide levels were determined at fasting and six minutes after intravenous injection of 1 mg of glucagon.
RESULTSBoth fasting and 6-minute post-glucagon-stimulated C-peptide levels in T1D patients were significantly lower than those of T2D patients (0.76 +/- 0.36 ng/mL vs. 1.81 +/- 0.78 ng/mL, P < 0.05; 0.88 +/- 0.42 ng/mL vs. 3.68 +/- 0.98 ng/mL, P < 0.05). In T1D patients, the C-peptide level after injection of glucagon was similar to the fasting level. In T2D, patients treated with diet or oral drug had a significantly greater fasting and stimulated C-peptide level than those patients received insulin therapy (2.45 +/- 0.93 ng/mL vs. 1.61 +/- 0.68 ng/mL, P < 0.05; 5.26 +/- 1.24 ng/mL vs. 2.15 +/- 0.76 ng/mL, P < 0.05). The serum C-peptide level after glucagon stimulation was positively correlated with C-peptide levels at fasting in all three groups (r = 0.76, P < 0.05).
CONCLUSIONSThe 6-minute glucagon test is valuable in assessing the function of islet beta cell in patients with diabetes mellitus. It is helpful for diagnosis and treatment of diabetes mellitus.
