1. Influence of sulfonylureas on cardiovascular system: Progress in basic research and clinical research
Academic Journal of Second Military Medical University 2010;28(9):1008-1010
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 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.
