Previous studies have showed that sulfonylureas possess a bidirectional effect on cardiovascular system: they can raise the coronary artery tone, aggravate ischemic injury to the cardiovascular tissues, and accelerate cardiac hypertrophy through closing cardiovascular ATP-sensitive K+ channels; meanwhile, they can also regulate glucolipid metabolism, modulate inflammatory reaction and inhibit atherosclerosis through activating peroxisome proliferator-activated receptors. Clinical-epidemiological study showed different opinions on whether sulfonylureas can increase the mortality of patients with cardiovascular diseases.

AIM: To evaluate the effects of glycemic control on refraction in diabetic patients. METHODS: Twenty newly diagnosed diabetic patients were included in this study. The random blood glucose, HbA1c levels, fasting C-peptide and postprandial 2h C-peptide were measured before treatment. The patients with random blood glucose higher than 12.0mmol/L and HbA1c level higher than 10.0% were selected. Refraction, intraocular pressure, radius of the anterior corneal curvature, depth of the anterior chamber, lens thickness, vitreous length, and axial length were measured on admission and at the end of week 1, 2, 3 and 4 during glycemic control.RESULTS: A transient hyperopic change occurred in all the patients receiving glycemic control. The maximum hyperopic change was 1.60D (range 0.50±3.20D). Recovery of the previous refraction occurred between two and four weeks after insulin treatment. There was a positive correlation between the maximum hyperopic changes and the HbA1c levels on admission (r=0.84, P<0.05). There was a positive correlation between the maximum hyperopic changes and the daily rate of blood glucose reduction over the first 7 days of the treatment (r=0.53, P<0.05). During transient hyperopia, no significant changes were observed in the intraocular pressure, radius of the anterior corneal curvature, depth of the anterior chamber, lens thickness, vitreous length and axial length.CONCLUSION: Transient hyperopic changes occur after glycemic control in diabetic patients with severe hyperglycemia. The degrees of transient hyperopia are highly dependent on HbA1c levels before treatment and the rate of reduction of the blood glucose level.

Objective To evaluate if expression of serum retinol-binding protein 4 (RBP4) concentrations in cholesterol gallstone disease.Methods Serum RBP4 levels of 100 cholesterol gallstone disease patients (cholesterol gallstone disease group) and 147 healthy controls (healthy control group) were measured by enzyme-linked immunosorbent assay and further correlated with clinical and biochemical characteristics,including insulin resistance and renal function.The chemical composition of gallstones was determined by postoperative pathology.Results The level of RBP4 in cholesterol gallstone disease group was significantly lower than that in healthy control group [(30.57 ± 13.64 ) mg/L vs.(41.52 ± 20.25 ) mg/L](P＜ 0.01 ).The level of RBP4 was also associated with gallstone occurrence (OR =0.93,95％ CI:0.88 -0.96,P =0.004).Serum RBP4 levels of all subjects were positively correlated with total cholesterol,triglyceride,creatinine,insulin resistance and albumin ( P ＜ 0.05 or ＜ 0.01 ),and negatively correlated with aspartate aminotransferase (P ＜0.01).In multivariate analysis,cholesterol gallstone formation was significantly associated with a lower serum RBP4 level (OR =2.97,95％ CI:1.15 -7.68,P =0.025 ).Both gallstone patients and controls were subdivided into two groups according to ceatinine:≥ 88.40 μ mol/L group and ＜ 88.40 μ mol/L group.Patients with gallstones were found to have significantly lower serum RBP4 levels than controls in both subgroups (P =0.012,0.045 ).According to GFR,both gallstone patients and controls were subdivided into ≥ 90 ml/(min· 1.73 m2) group,60 - 89 ml/(min· 1.73 m2) group and ＜60 ml/ (min· 1.73 m2) group.It showed that a lower GFR was associated with greater serum RBP4 level in healthy control group.This trend was not noted in cholesterol gallstone disease group.Conclusions Serum RBP4 decreases in cholesterol gallstone disease independent of renal function.The relationship between liver function and RBP4 level in these patients deserves further investigation.

Objective To evaluate effects of glycemic control on refraction in diabetic patients.Methods Twenty newly diagnosed diabetic patients were included in this study. The random blood glucose,glycosylated hemoglobin A1c( HbA1c) levels, fasting C-peptide and postprandial 2 h C-peptide levels were measured before treatment. The patients with random blood glucose ≥ 12. 0 mmol/L and HbA1c ≥ 10. 0%were selected. Refraction, intraocular pressure, radius of the anterior corneal curvature, depth of the anterior chamber, lens thickness, vitreous length, and axial length were measured on admission and at the end of week 1,2, 3 and 4 during glycaemic control. Results A transient hyperopic change occurred in all the patients receiving glycemic control with a mean maximum hyperopic changes of 1.6 D ( 0. 50 D ～ 3.20 D). There was a positive correlation between the magnitude of the maximum hyperopic changes and the HbA1 c levels on admission ( r = 0.84, P ＜ 0.05 ). There was a positive correlation between the magnitude of the maximum hyperopic changes and the daily rate of blood glucose reduction over the first 7 days of the treatment ( r = 0.53, P ＜ 0.05 ). There was no significant correlation between the magnitude of the maximum hyperopic changes and the levels of random blood glucose on admission. No significant correlation was observed between the maximum hyperopic changes and fasting C-peptide or postprandial 2 h C-peptide.There were no significant correlations between the magnitude of the maximum hyperopic changes and age,blood press, body mass index, triglyceride, total cholesterol, low-density lipoprotein or high-density lipoprotein. No significant changes were observed in the intraocular pressure, radius of the anterior corneal curvature, depth of the anterior chamber, lens thickness, vitreous length and axial length during glycemic control. Conclusions Transient hyperopic changes occur after glycemic control in diabetic patients with severe hyperglycaemia. The degrees of transient hyperopia are highly dependent on HbA1c levels before treatment and the rate of reduction of glucose level over the first 7 days of treatment. This is probably due to the decrease of refractive power by lens hydration, not morphological change of lens.

OBJECTIVETo find out an effective therapy for obesity induced by antipsychotic agents.

METHODSOne hundred and one cases of obesity who were being treated with antipsychotic agents were randomly divided into an observation group and a control group. The observation group were treated with electroacupuncture at Quchi (LI 11), Zusanli (ST 36), Fenglong (ST 40), Shangjuxu (ST 37) and Xiajuxu (ST 39), once a day for 8 weeks; and no treatment was given to the control group. The Brief Psychiatric Rating Scale (BPRS) was used for assessment of therapeutic effect and the Treatment Emergent Symptom Scale (TESS) for adverse effects.

RESULTSThe clinically effective rate of the observation group (54.9%) was superior to the control group (10.0%) with a significant difference between the two groups (P<0.05). The BPRS score-reducing rate was 24.92% and 28.62% in the both groups respectively, and with no adverse effects.

CONCLUSIONElectroacupuncture has a good therapeutic effect on obesity induced by antipsychotic agents, and it improves the patient's compliance with no adverse effect.

The impact of key physical properties on granulated products by the high-speed mixing wet method was studied. Andrographis extracts were utilized as the model drug. Four processing methods were adopted to prepare mixed powder of microcrystalline cellulose (MCC) and starch with the mass ratio 1:0.5, 1:1 and 1:2 by the high-speed mixing wet method. The properties of the prepared granules were evaluated with such indexes as granule yield, the ratio of lumps and fine powder, granule-AOR and granule-HR. The impact of key physical properties on granulated products was analyzed through stepwise regression analysis. The results showed that angle of repose, moisture content, pore volume, density and contact angle with water were key physical properties of the powder. The key physical properties of Chinese medical extracts powder are the important factor impacting granulated products made by the high-speed mixing wet method. In this study, the impact of key physical properties on granulated products of Chinese medical extracts was analyzed from the physical angle.
