Objective To discuss the clinical effect and safety on rosiglitazone applied to patients with early type 2 diabetic nephropathy.Methods Ninety-six patients with early type 2 diabetic nephropathy were divided into the control group(n=48) and the research group (n =48).The patients of the control group were given mefformin treatment, while of research group were given rosiglitazone, both the courses were three months.The urinary albumin excretion rate (UAER), 24 h urine trace albumin (UAE), serum creatinine clearance (SCr) , fasting plasma glucose (FPG), postprandial blood glucose (2 hPG), glycosylated hemoglobin (HbA 1 c), triglycerides (TG), cholesterol (TC), low density lipoprotein (LDL-C), high density lipoprotein (HDL-C) before and after treatment and clinical effect between the two groups were compared.Results The HbA1c, FPG, 2 hPG, UAER, UAE, TC, TG of after treatment of all patients decreased obviously,while the HDL-C level increased remarkably, and compared with control group the differences were significant (HbA1 c: (7.32±0.84)％ vs (7.56±0.98)％, FPG: (8.02± 1.42) mmol/L vs (8.16± 1.54) mmol/L, 2 hPG: (11.54±2.11) mmol/L vs (12.02±1.97) mmol/L,UAER: (67.34±6.45) mg/24 h vs (52.56±5.35) mg/24 h,UAE: (108.64±22.64) mg/d vs (68.84± 11.43) mg/d, TC : (5.44± 0.72) mmol/L vs (4.76± 0.51) mmol/L, TG: (2.04± 0.53) mmol/L) vs (1.73±0.46) mmol/L);t =-4.172,-3.973,-4.026,-4.263,-6.634,-5.737,-5.635, -4.735,-4.633;P＜O.05).While there were no statistical significance about SCr before and after treatment(P ＞0.05).The total clinical effect of the research group was obviously higher than that of the control group (87.5％ (42/48) vs 66.7％ (32/48), x2 =5.363,P =0.035).There were not obvious adverse reaction occurred during treatment for all patients.Conclusion Rosiglitazone can effectively reduce the blood glucose in patients with early type 2 diabetic nephropathy and reduce urinary protein excretion, the effect is more obvious than that of metformin.

he blood supply of corpus callosum is rich, its function is complex, and the incidence of infarction is low. The risk factors and etiology for callosal infarction do not have any difference with the infarction in other parts of the brain. The clinical manifestations of the disease are complex and diverse. The two classical clinical manifestations are callosal disconnection syndrome and frontal-type gait disorder, but hemiplegia, monoplegia, apraxia, and mental retardation are common in clinical practice. The positive rate of CT scan is lower. MRI has higher sensitivity and specificity for callosal infarction. The diagnosis of callosal infarction is not difficult according to the history and imaging examination, however, it needs to be differentiated with other diseases that likely involve corpus callosum. Most of the patients with callosal infarction have good prognosis.

Objective To investigate the clinical features,safety and clinical efficacy of the posterior decompression and interbody fusion with internal fixation for complete thoracolumbar fracture and dislocation.Methods The clinical data of 23 patients with complete thoracolumbar fracture and dislocation treated by posterior decompression and interbody fusion with pedicle screw fixation from August 2011 to October 2014 were retrospectively analyzed.There were 18 males and 15 females,aging from 20 to 50 years old with an average age of 38.2±0.3 years.There were 8 cases of T10,11 vertebral dislocation,8 of T11,12 vertebral dislocation,3 of T12L1 vertebral dislocation,and 4 of L1.2 vertebral dislocation.All the patients had different degrees of multiple rib fractures and pneumothorax complications.Preoperative spinal cord nerve function was evaluated according to the American Spinal Injury Association of spinal cord function (ASIA).There were 10 cases of ASIA grade A and 13 cases of grade B.Operation time,intraoperative blood loss,clinical outcome,imaging X-ray and CT examination,segmental kyphosis angle and bone graft fusion were recorded.Results All the patients were followed up for 13 to 26 months,average 20.2±4.3 months.The operation time ranged from 150 to 260 min with the average time of 180.3± 14.8 min;intraoperative blood loss was 800-1 500 ml with the average of 950.2±98.1 ml.Preoperative sagittal Cobb angle was-13.5° ±6.3° (range,-20.1° to 2.3°);postoperative sagittal Cobb angle was 1.43°±6.4° (range,-7.6° to 3.5°);at the latest follow-up,sagittal Cobb angle was 1.6°±6.3° (range,-8.1° to 10.3°);the dislocation reduced from preoperative 100％ to postoperative 0-15％ (10％±6％).After operation,the ASIA grade of 2 cases improved from A to B,and 5 cases improved from B to C.All of the patients had bone fusion after operation,no false joint or nonunion occurred,no loosening or breakage of internal fixation occurred.Conclusion There are high risks and difficulty of surgery for those who with thoracolumbar fracture dislocation and severe injuries of spine and spinal cord combined with multiple injuries.Proper treatment of preoperative complications is the premise of good curative effect;reliable fusion and long segment internal fixation is the key of operation.Single posterior decompression and reduction with interbody fusion and internal fixation is less invasive and could achieve satisfactory clinical efficacy.

Objective: To study if the immune-enhancing effect of Arg was mediated via liver.Methods: The direct effect of Arg on T cell proliferation was measured by 3H-TdR incorporation. Rat hepatocytes were primarily cultured in serum-free DMEM/F12 medium, and then cultured in medium containing Arg(?mol/L:0,7.5,75,750,7 500), and the supernatant was collected at 0, 24, 48, 72 hours, and added to splenocytes culture, and T cell proliferation, NK cell activity and IL-2 activity,〔Ca 2+〕i were measured respectively.Results: Arg had no direct effect on splenocyte proliferation. The hepatocyte culture supernatant significantly increased the lymphocyte〔Ca 2+〕i ,IL-2 activity and T lymphocyte proliferation; 7 500 ?mol/L was most effective. Conclusion: Arg may enhance immune function via secretion of bioactive molecules by hepatocytes.

Objective To study the sectional anatomy of the cardiac septum to provide the reference for clinical imageology and surgery. Methods Sixteen normal adult hearts without organic lesions were verified macroscopically. After vascular perfusion, the specimens were embedded with gel, fixed with 5% formalin, and cryopreserved for a week, and then were sectioned with the Digital Sectioner. Results A total of 1 608 slices (thickness: 0.2 mm) of the heart were obtained. Cardiac septum and the surrounding structures were shown clearly. The demarcation of connective and muscular tissues was clear. The diameters of the cardiac apex, fossa ovalis, brawny intraventricular septum, left ventricle, right ventricle, left and right fibrous trigone were measured with Photoshop6.0. Conclusion The clear images can display tiny structures that could be measured, which could provide anatomical references clinical imageology and surgery.
