Methods Patients with gerontol delirium diagnosed between January 2011 and January 2013 were identified by a retrospective review of records in the Nanjing General Hospital of Nanjing Military Command .Totally 132 patients were included , 59 females and 73 males, with a median age of 71.4 years (range 65-97).The diagnostic criteria were based on the DSM-Ⅳ and Delirium Rating Scale.Dementia, depression, mental retardation and other cognitive dysfunction were excluded .General condition of patients , etiology , clinical features , treatment and prognosis were all performed using the SPSS 20.0 for windows.A P value of <0.05 was considered as significant . Results Disturbance of consciousness were observed in all 132 patients.Old age, coma and serious infection in the course , endotracheal intuba-tion and(or) tracheotomy, a variety of basic diseases all come up with poor prognosis . Conclusion Delirium progresses quickly. Etiological treatment can help to control the conditions of delirium .

Objective To evaluate the effect of keeping atrial septal fenestration in correction of total anomalous pulmonary venous connection (TAPVC) with left ventricular hypoplasia.Methods We reviewed 44 TAPVC patients between June,2006 and June,2013 in Shanghai Xinhua Hospital.According to whether keeping atrial septal fenestration during operation,patients were divided into group A(keeping fenestration,25 cases) and group B(no fenestration,19 cases).Retrospective statistical analysis was carried on the in-patient data and follow-up outcomes.Results No statistically significant differences between the two group on age,weight,left ventricular volume and crossclamp time (P ＞ 0.05).While cardiopulmonary bypass time,ventilation time,dosage of positive inotropic drugs,and ICU stay time of group A were shorter compares with group B (P ＜ 0.05).4 patients in group A (16.00％) suffered from low cardiac output syndrome (LCOS) postoperatively,and 6 in group B(31.58％).Pulmonary edema occurred in 3 patients,1 in group A(4.00％),and 2 in group B(10.53％).Total post-operative mortality was 6.82％ (3/44).2 cases died of serious LCOS(1 from group A,and the other from group B),1 cases died of infection and multiple organ dysfunction syndrome(group B).No significant difference of mortality was observed between two groups.Follow-up data showed some fenestrations can close naturally.Conclusion Keeping atrial septal fenestration can be done as a feasibility tactic in correction of TAPVC with left ventricular hypoplasia.

Objective To extract principal components from valuable indicators on conventional ultrasoundand contrast-enhanced ultrasound (CEUS) in the differential diagnosis of thyroid benign and malignant lesions and to discuss the diagnostic value of each indicator.Methods One hundred and three patients with 125 thyroid lesions (65 malignant lesions and 60 benign lesions) underwent preoperative grayscale ultrasound (GSUS),color Doppler ultrasound (CDUS) and CEUS examinations.Eighteen indicators were chosen to evaluate every lesion and principal components were extracted by principal component and valuable indicators were ordered by importance.Results There were significant differences on GSUS and CEUS indicators between benign and malignant lesions.The first principal component was the representation of contrast enhanced ultrasound and was valuable in the differential diagnosis of thyroid benign and malignant lesions.The rank of valuable CEUS indicators were homogeneity of enhancement,filling defect,relative arrival time of periphery,peak interior echogenicity,relative arrival time of interior,peak peripheral echogenicity and ring enhancement.Conclusions GSUS and CEUS are valuable in the differential diagnosis of thyroid benign and malignant lesions.

The relationship between visfatin.endothelin, and insulin resistance in the pathogenesis of type 2 diabetes mellitus was explored. Endothelin, visfatin, and other markers were compared. Plasma visfatin was reduced after therapy. Endothelin was positively correlated with fasting insulin, HOMA-IR, HOMA-p, and visfatin. Visfatin was positively correlated with endothelin, HbA1C , fasting insulin, and HOMA-IR. HOMA-IR was an independent related factor in influencing visfatin. The visfatin is related to endothelin and insulin resistance, which may contribute to the pathogenesis of insulin resistance and type 2 diabetes mellitus.

Objective This study aims to investigate the effects of high-fat diet rich in perilla oil on the insulin sensitivity-related gene expression in skeletal muscle in insulin resistant rats.Methods The insulin resistant ( IR) rat models were randomly divided into 2 groups, including high fat group ( HF) and perilla oil ( PO) intervention group fed with 20%substitution of lard energy in the HF.The insulin sensitivity of rats was measured after 4 weeks.Theα-linolenic acid ( ALA) content of PO in the rat plasma were analyzed by gas chromatograph.Real-time PCR was applied to measure glucose transporter 4 ( GLUT4 ) and insulin receptor substrate-1 ( IRS-1 ) mRNA, and Western blot assay was used for detecting the expression of GLUT4 and IRS-1 in the skeletal muscle.Results At the gene and protein levels, PO remarkably reduced the level of IRS-1 and upregulated the level of GLUT4 with increasing intake of ALA and serum ALA content in IR rats.The results of hyperinsulinemic-euglycemic clamp test showed no significant difference between the two groups.Conclusions The results of our study suggest that consumption of n-3 PUFA at levels that can typically be found in the diet fed to IR rats in the form of ALA (0.556 g/d) may not improve insulin sensitivity, even though regulating the expression of GLUT4 and IRS-1 in the skeletal muscle.
