ABSTRACT
Objective To investigate the effects of a standard food-based low calorie diet and meal replacements on compliance,weight loss,and glycolipid metabolism in obese patients,and to provide an optimal nutritional weight reduction method for obese individuals in China.Methods Height,weight,waist circumference,body mass index (BMI),body fat,visceral fat in low calorie diet group (n =23) and meal replacements group (n =17) were assessed at baseline,4 and 8 weeks after the intervention.Fasting plasma glucose (FPG),triglyceride (TG),total cholesterol (TC),high density lipoprotein-cholesterol (HDL-C),low density lipoprotein-cholesterol (LDL-C),aspartate aminotransferase (AST),alanine transaminase (ALT),gamma-glutamyl transpeptidase (GGT),alkaline phosphatase (ALP),fasting insulin (FINS),and homeostasis model assessment for insulin resistance (HOMA-IR) were assessed at both baseline and 8 weeks after the intervention.Results Both low calorie diet and meal replacements led to significant decreases in body weight,waist circumference,BMI,body fat,and visceral fat(all P＜0.01) after 4 and 8 weeks.Body fat (P＜ 0.01) and total body water (P＜ 0.05) in low calorie diet group were decreased more obviously compared with those in meal replacements group at 4 weeks.However,there were no difference in all these parameters between two groups at 8 weeks (P＞0.05).Both groups experienced improvements in biochemical outcomes and metabolic indicators.TG,AST,ALT,GGT,ALP,FINS,and HOMA-IR levels were all decreased (P＜0.05 or P＜0.01) while HDL-C level was increased (P＜0.01) 8 weeks after standard food-based low calorie diet.FPG,TG,TC,LDL-C,AST,ALT,ALP,FINS,and HOMA-IR levels were declined 8 weeks after meal replacements(P＜0.05 or P＜0.01).TC,LDL-C,and ALT levels were more evidently to reduce in meal replacements group compared with low calorie diet group.Conclusions Present data suggest that meal replacements and low calorie diet may have a similar effect on weight loss,while meal replacements seems to obtain a better metabolic results.
ABSTRACT
Objective@#To compare the weight loss and metabolic profile between a continuous energy-restricted diet and intermittent fasting diet in order to present an optimal nutritional weight reduction method for obese people in China.@*Methods@#Sixty overweight or obese adults were selected and divided into two groups as the continuous energy-restricted diet group and the intermittent fasting diet group.

ABSTRACT
Objective To evaluate left ventricular myocardial function altemation by three-dimensional speckle tracking imaging (3D-STI) after surgical aortic valve replacement (AVR) in severe aortic stenosis (AS) patients with preserved left ventricular ejection fraction (LVEF),and discuss its clinical value.Methods Forty patients with severe aortic stenosis who were hospitalized or outpatient in Nanjing First Hospital Affiliated to Nanjing Medical University during the period of October 2014 to October 2016 (AS group),and forty healthy volunteers (normal control group) were enrolled in this study.Normal control group underwent conventional echocardiography and 3D-STI measurement,while the AS group underwent conventional echocardiography and 3D-STI measurement at preoperative,1 week postoperative and 3 months postoperative,then we obtained left ventricular end-diastolic diameter (LVEDD),left ventricular end-systolic diameter (LVESD),interventricular septum thickness diameter (IVSd),left ventricular posterior wall thickness diameter (LVPWd),left ventricular ejection fraction (LVEF),global longitudinal strain (GLS),global circumferential strain (GCS),global radial strain (GRS),global area strain (GAS) strain and 3D-strain.The independent sample t test was used to compare the difference of conventional ultrasound parameters and 3D-STI parameters between AS preoperative patients and healthy controls,AS patients at 3 months postoperative and healthy controls.The single factor analysis of variance was used to compare the difference of conventional ultrasound parameters and 3D-STI parameters in severe patients at preoperative,1 week postoperative and 3 months postoperative.LSD-t test was used to compare in different AS groups.Results Compared with normal control group,IVSD,LVPWD and GCS of severe AS patients increased significantly (t=13.824,11.298 and-6.584,all P ＜ 0.001),GLS,GRS and 3D-Strain decreased significantly (t=10.221,-6.237 and-5.674,all P ＜ 0.001),LVEDD,LVESDand GAS had no significant difference.Compared with preoperative AS patients,LVEF,GLS,GAS and GCS decreased significantly (t=-2.205,-2.093,-2.034 and-3.152,all P ＜ 0.05 or 0.01) at 1 week postoperative,LVEDD,LVESD,IVSD,LVPWD,GRS and 3D-strain had no significant difference at 1 week postoperative;GLS,GRS and 3D-strain increased significantly (t=5.446,-4.923 and-4.388,all P ＜ 0.05 or 0.01) at 3 months postoperative,GCS,IVSD and LVPWD decreased significantly (t=-3.988,4.794 and 4.211,all P ＜ 0.05 or 0.01) at 3 months postoperative,LVEDD,LVESD,LVEF and GAS had no significant difference at 3 months postoperative.Compared with AS patients at 1 week postoperative,LVEF,GLS,GRS,GAS and 3D-strain increased significantly (t=-2.631,7.383,-4.719,2.923 and-4.154,all P ＜ 0.05 or 0.01) at 3 months postoperative,GCS,IVSD and LVPWD decreased significantly (t=-2.109,4.747 and 4.323,all P ＜ 0.05 or0.01) at 3 months postoperative.But in AS patients at 3 months postoperative,IVSD,LVPWD,GLS and GCS were still higher than those of normal control group (t=9.809,7.066,4.752 and-2.553,all P ＜ 0.001 or ＜ 0.05),LVEDD,LVESD,LVEF,GRS,GAS and 3D-strain had no significant difference.Conclusion The alternation of left ventricular myocardial function have a certain characteristic before and after aortic valve replacement in severe aortic stenosis patients with preserved LVEF,and 3D-STI can evaluate it more accurately.
ABSTRACT
Objective To discuss the value of leukocyte-targeted myocardial contrast echocardiography (MCE) as a tool in observing the degree of acute rejection after heart transplantation. Methods Abdominal heterotopic cardiac transplantation was performed on 32 rats successfully, among which 8 isografts served as group A, and groups B, C and D involved 8 allografts respectively. The rats in groups B and C were treated with cyclosporine A (CsA) at a high dose (10mg· kg-1 · day-1 ), a low dose (3 mg · kg-1 · day-1 ) from 3rd day before transplantation respectively.The rats in groups A and D were untreated with CsA. MCE was performed during continuous intravenous SonoVue injection postoperatively on the third day after operation. We performed 2 types of MCE: perfusion imaging and leukocyte-targeted imaging. The images were obtained at 20 s and 5 min after injection of contrast agent. The value of the contrast image grayscale (GS) was measured by image analyzer (GS20s, GS5 min). GStarget was calculated as the GS5min minus the GS20s in the same rat.Postmortem histology was performed after observation. The degree of myocardial rejection was determined by HE-stained graft myocardium. Immunohistochemistry was performed to quantify the CD3-positive cells, and correlation analysis was performed between CD3-positive cell count and GS20s,GS5min, GStarget. Results Perfusion imaging showed no significant difference in myocardial GS20s of each group. Leukocyte-Targeted imaging exhibited a clear gradient in these groups (P＜0. 05). There was significant difference in GStarget of each group (P＜0. 001). Postmortem histology showed 0- Ⅰ grade rejection in group A, Ⅰ -Ⅱ grade rejection in group B, Ⅱ-Ⅲ grade rejection in group C, Ⅲ-Ⅳ grade rejection in group D. Immunohistochemistry revealed the CD3-positive cell infiltration was increased in turn from the group A to the group D. There was a significantly positive correlation between the CD3-positive cell count and GStarget ( r = 0. 86, P ＜ 0. 001 ). Conclusion Leukocyte-targeted contrast echocardiography may thus offer a noninvasive and effective ultrasound imaging technique for detecting the degree of acute cardiac transplant rejection.
