Objective To observe the influence of pioglitazone on the expression of adiponectin in the liver of high fat diet-induced obese rats.Methods Forty male SD rats were randomly divided into control group which received regular diet ( n =10),high fat diet group ( n =15 ) and high fat diet goup administened pioglitazone ( n =15 ) on high fat diet.After twelve weeks,fasting blood glucose,fasting serum insulin,triglyceride,total cholesterol,and the histomorphologieal changes in liver were observed;insulin sensitivity test was performed;the fatty experimental group are treated with Pioglitazone(30mg · kg-1 · d-1,oral gavage),treatment was administered daily for 2 weeks.The control group and fatty control group all received an equal volume of vehicle (saline).The protein expression of adiponectin in the liver of rats was determined by immunohistochemistry.Results The insulin sensitive index was significantly decreased in the high-fat-diet rats compared with the control group[(0.021 ±0.010),(0.015 ±0.007),P ＜0.05] ;The protein level of adiponectin in the liver of fatty,control group was significantly decreased compared with the control group[(2929.73 ± 157.45 ),(3814.21 ±211.42),P ＜0.05],adiponectin in the liver of fatty experimental group was significantly increased compared with the fatty control group[(2929.73 ± 157.45),(3657.68 ±217.31 ),P ＜0.05].Conclusion Pioglitazone could improve the expression of adiponectin,and improve the resistance of insulin.

Objective To study the preventive and therapeutic effects of blood pressure control on hematoma expansion and neurological function in patients with ultra-early basal ganglia intracerebral hemorrhage.Methods From November 2009 to November 2011,120 patients with ultra-early basal ganglia intracerebral hemorrhage from our Hospital were enrolled and randomly divided into intensive blood pressure reduction group and general blood pressure reduction group in equal numbers (n =60).The antihypertensive agent were used intravenously to reduce the systolic blood pressure by 130-140 mm Hg within l hour after treatment in patients of intensive blood pressure reduction group; and the general blood pressure reduction group was control by 160-180 mm Hg.The blood pressure of patients in both groups was maintained for 24 hours.The volume of haematoma in CT was measured before and 24 hours after treatment.The National Institutes of Health Stroke Scale (NIHSS) score was assessed 24 hours before and after treatmentand 14 days after treatment respectively.Statistical analyses were conducted.Results Between 24 hours before and after treatment,therewere significant difference in the hematoma volume((11.99 ± 6.90) ml vs.(14.74 ± 7.75) ml,t =2.049,P =0.043) and the number of cases of hematoma enlargement(5 vs.14,x2 =5.07,P =0.024) between the two groups.Between 24 hours before and after treatment,there was no significant difference in NIHSS scale in intensive blood pressure reduction group ((9.74 ± 4.49) vs.(9.25 ± 4.10),P ＞ 0.05).Between 24 hours before and 2 weeks after treatment,there were significant difference in NIHSS scale in both groups ((9.74 ± 4.49) vs.(6.28 ± 3.68),P ＜ 0.05 ; (9.50 ± 4.81) vs.(7.82 ± 4.28),P ＜ 0.05,respectively).At two weeks after treatment,there was significant difference in NIHSS scale between two groups ((6.28 ± 3.68) vs.(7.82 ± 4.28),P ＜ 0.05).Conclusion Intensive reduction of blood pressure is safe for the treatment of ultra-early basal ganglia intracerebral hemorrhage and reduce the incidence of hematoma enlargement and improve patient's early neurological function.
