Objective To investigate the characteristics of cognitive changes in type 2 diabetes mellitus pa-tients complicated with stroke. Methods One hundred and one stroke patients were recruited and allocated to thetype 2 diabetes mellitus group (34 patients) and sixty-seven patients in the control group (67 patients) according tobeing with or without type 2 diabetes mellitus. All the patients were evaluated, after 3 weeks, 6 months and 12months of onset of stroke, with regard to their cognitive functions by using the Mini-mental State Examination(MMSE) and Montreal Cognitive Assessment (MOCA). Results Average scores obtained in MMSE and MOCAtests were significantly lower at 3 weeks and 6 months after onset in the type 2 diabetes mellitus group when comparingwith control group. In the type 2 diabetes mellitus group, no significant difference was observed between 3 weeks and6 months after onset of stroke with regard to scores of MMSE and MOCA ( P > 0.05 ), however, the score at 6 monthswas significantly lower than that at 12 months after onset (P <0.05). On the other hand, scores of MMSE (P >0.05 ) and MOCA (P > 0.05 ) in the control group were not any statistically different among various time points ofobservation. Conclusion Type 2 diabetes mellitus will aggravate cognitive dysfunctions of stroke patients, whichstarted to recover in 6 months of onset of the stroke.

Objective To investigate the effect of enteral nutrition (EN) on the T lymphocytes-mediated immune function in patients with acquired immune deficiency syndrome (AIDS). Methods Totally 79 AIDS patients were randomly divided into enteral nutrition ( EN ) group ( supported with EN daily in addition to conventional treatment; n = 46) and control group (underwent conventional treatment only; n = 33 ). T lymphocytes including CD3, CD4, and CD8 cells as well as blood biochemical parameters including alanine aminotransferase ( ALT), aspartate aminotransferase (AST), glucose ( Glu ), total protein (TP), albumin ( ALB ), blood urea nitrogen (BUN) , Cr, and prealbumin (PA) were determined immediately before management (T0) and on the 30th day(T1). Results ALT, AST, Glu, TP, ALB, BUN, Cr, and PA showed no significant differences between these two groups before management ( all P ＞ 0. 05 ). The levels of TP ( P = 0. 015), ALB ( P = 0. 007 ), and PA ( P =0. 022 ) were significantly higher in EN group than those in control group at T1. The cell counts of CD3, CD4, and CD8 were not significantly different at T0, while the cell count of CD4 was significantly higher in EN group than that in control group at T1 ( P ＜ 0. 05 ). Conclusion EN can improve the nutritional status and T lymphocytesmediated immune function in AIDS patients.

Background The key premise of genetic research and treatment is to select the desired gene vector,ultrasound microbubbles as a new type of gene vector can safe,fast and effectively enhance the gene transfection and expression by reversibility increasing the permeability of cells. Objective This study was to observe the effects of ciliary neurotrophic factor(CNTF)gene mediated by ultrasound microbubbles intraocular transfer on visual function and retinal ganglion cell(BGCs)after optic nerve injury. Methods Fifty-five adult Sprague-Dawley(SD)rats were divided into 6 groups randomly,including normal control group(n=5),sham injury group(n=10),simple injury group(n=10),naked plasmid group(n=10),plasmid+ultrasonic irradiation group(n=10)and ultrasound microbubbles group(n=10).The model of optic nerve injury Was made by forceps clip on the fight optic nerve.and the corresponding intervene was performed in different groups.Flash visual evoked potential(F

Objective To investigate the effects of captopril on cardiac function and levels of energy-rich phosphates in pressure overload induced left ventricular hypertrophy rats. Methods One hundred and twenty SD rats were randomly divided into three groups: sham operation group (SH group, n=40),coarctation of abdominal aorta group (CAA group, n=40) and captopril treatment 1 mg· 1001·d-1) group (CAP group, n=40). Left ventricular end-diastolic pressure (LVEDP), left ventricular mass index (LVMI), levels of energy-rich phosphates and morphological changes of the myocardial mitochondria were compared at the 6th and 8th week after operation. Results At 6th week, in CAA group, LVMI and LVEDP were increased and ±dp/dtmax was decreased, while ATP and ADP were decreased and AMP was increased (P<0.01). These changes were much obvious at 8th week (P<0.01). Compared with those of CAA group, the parameters of heart function and energy-rich phosphates (ATP, ADP, AMP, TAN) in CAP group were improved significantly(P<0.01) at the 6th and 8th week. In CAP group, the parameters of heart function and energy-rich phosphates (ADP, AMP, TAN) were much better at 8th week than those at 6th week. The morphological change of mitochondria was less in CAP group than that in CAA group. Conclusion Captopril significantly improves myocardial energy metabolism in pressure overload rats and protects the function of myocardial mitochondria.

Objective To investigate whether systemic inflammatory response syndrome(SIRS) after cerebral infarction is associated with poor outcome and its associated clinical factors.Methods We prospectively studied 500 patients with cerebral infarction.recorded the associated clinical factors on presentation and calculated the mortality at 21 st day.Results There are 85 SIRS patients in 500 patients with cerebral infarction,31 with total anterior cerebral infarction(TACI),34 with partial anterior cerebral infarction(PACI),15 with posterior cerebral infarction(POCI)and 5 with lacunar cerebral infarction (LACI).The frequency of SIRS was positively correlated with mortality rate according to Oxfordshire Commanity Stroke Project(OCSP)subtypes in cerebral infarction patients with fever(Spearman correlation coefficient=1.0:P＜0.001).Single factor analysis showed that the risk factors for both SIRS and mortality of cerebral infarction were as follows:age,infection,48h Chinese Stroke Scale score,48h Glassgow score,OCSP subtypes and dysphagia.Diabetes Was the risk factor for SIRS.but had no effect on mortality.On Cox regression,48h Glassgow score was the sole independent risk factor of outcome.However.if SIRS was included in the formula.P＞0.05.ConclusionsSIRS is the predictor of poor outcome after acute cerebral infarction.It is important to prevent SIRS especially in TACI and POCI.Diabetes is the risk factor for SIBS.but has no effect on mortality.

Objective To summarize the surgical experience gained from robotic mitral valve replacement (MVR), and demonstrate the long-term clinical follow-up results. Methods From Jan. 2007 to Jan. 2015, more than 700 patients underwent various types of robotic cardiac surgery in the Department the authors served in, and of them 43 patients underwent robotic MVR with da Vinci Surgical System (Intuitive Surgical, USA). Among the 43 patients, the average age was 47±11 years (ranged 19-65 years), and sex ratio (female to male) was 0.8:1. Six patients were with heart function of NYHA class Ⅰ, 30 patients were of NYHA class Ⅱ and 7 patients were of NYHA class Ⅲ. The left ventricular ejection fraction (LVEF) were 54%-78% (64.0%±7.1%), and 20 patients had atrial fibrillation on admission, and 35 patients were with rheumatic mitral stenosis (MS). Atrial septal defect (0.7cm in size) co-existed in 1 case and 1 patient had mild aortic regurgitation. Mechanical or bioprosthetic mitral valve was replaced via left atriotomy by using da Vinci robotic surgical system after cardiopulmonary bypass (CPB) set-up. Radiopaque titan clips was employed by Cor-Knot knot-tying device (LSI Solutions, Inc, Victor, NY) to anchor the prosthetic valve. Trans-esophageal echocardiography (TEE) was performed before and after surgery. The operative data were collected and patients were followed up at outpatient clinic regularly up to 6 years. Results All cases were performed successfully with the same surgery. No conversion to median sternotomy or operative mortality occurred. The average operation time was 292±62 minutes (ranged 140-450 minutes) with CPB time of 124±26 minutes and aortic occlusion time of 88±21 minutes. The postoperative mechanical ventilation support time was continued for 15±6 hours, and the average staying length in critical care unit was 4±1 days. No myocardial infarction, ventricular tachycardia or excessive bleeding was complicated. All patients were successfully followed up for a median of 3.5 years (ranged 1 month to 6 years). In the follow-up period, no incidence of death, stroke, re-operation due to prosthetic endocarditis or prosthetic failure was reported. However, 39.5% (n=17) patients still had atrial fibrillation after surgery. Conclusion Robotic MVR is a safe and effective procedure with excellent long term surgical outcome.
