Objective To determine the relationships between serum leptin levels and maternal weights in late pregnancy and cord blood leptin levels to birth weights, C peptide, insulin and insulin like growth factor (IGF II). Methods Fifty normal pregnant women at 37～38 weeks and their newborns were studied, and 29 non pregnant women were set as control. Venous blood was taken from women and from the cord at delivery. Blood leptin and cord blood C peptide, insulin, and IGF II were measured by radio immunoassay. Results The average leptin level in maternal sera was (13.62?3.68)?g/L, significantly higher than that in the control (6.60?3.04)?g/L and that in cord blood (8.05?4.61)?g/L. Maternal leptin levels were significantly correlated with maternal weights and body mass index (BMI. r =0.33, 0.35, P 0.05). Cord blood leptin levels were significantly correlated with birth weights and BMI ( r =0.54, 0.49, P 0.05). Significant difference of the cord leptin levels was not seen between the males and females. The cord blood C peptide was (0.86?0.35) ?g/L, insulin (8.49?4.76) mU/L and IGF Ⅱ(0.218?0.076) ?g/L. Cord leptin levels were correlated with C peptide levels ( r =0.37, P 0.05). Conclusions Maternal leptin levels in late pregnancy were significantly higher than those in normal non pregnant women and positively correlated with maternal weights and BMI. Cord blood leptin levels were positively correlated with birth weights and BMI of the newborns. The leptin levels of cord blood were correlated with those of C peptide but not insulin and IGF II.

Objective We conducted an in vivo study with the mouse model of Vib rio vulnificus infection to evaluate the efficacies of combination therapy with antimicrobia l agents. Methods Vibrio vulnificus (6.0?10 8 cfu/ml)was injected intraperitoneally into the right abdominal cavity. One hour, 2 hour and 3 hour after inoculation, 7 antimicrobial agents were given alone or in combination intraperitoneally at human therapeutic dose level. The numbers of survial mouse and the supermicrostr ucture change of organs w ere observed. 7 antimicrobial agents were Imipenem, Chloramphenicol, Doxycycline Hydrochloride, Netilmicin, Cefoperazone, Piperacillin, Levofloxacin. Res ults Two hours after infection, the mouse survival rates of groups trea ted with Chloramphenicol, Levofloxacin, Netilmicin, Cefoperazone was 100%. Howev er, the survival rates in the mouse treated by Piperacillin was 60% and the surv ival rate of in the mouse treated with Imipenem or Doxycycline Hydrochloride was 20%. The survival rate in the mouse treated with Cefoperazone combined with Lev ofloxacin, Cefoperazone combined with Netilmicin, or Netilmicin combined with Do xycycline Hydrochloride, was 100%. The supermicrostructure injure of the organs in the mouse recovered. Conclusions These results indicate that Chloramphenicol, Netilmicin, Cefoperazone and Levofl oxacin alone had satisfactory efficacy in the treatment of experimental Vibrio v ulnificus infection in mouse. The combination therapies of Cefoperazone with Lev ofloxacin, Cefoperazone with Netilmicin, and Netilmicin with Doxycycline Hydroch loride are more advantageous than using antimicrobial agent alone.

Aim To study clinical efficacy of valsartan,in comparison with amlodipine, in hypertentive patients with left ventricular hypertrophy. Methods 65 hypertentive patients with left ventricular hypertrophy is divided into two groups, with 33 cases in valsartan group and 32 cases in amlodipine group Valsartan 80～160mg and amlodipine 5～ 10 mg were taken by the patients in the two groups for 6 months respectively. 24 h ambulatory blood pressure monitoring ( 24 h ABPM) and color echocardiography were performed in the two groups before and after treatment. Results The parameters of 24 h ABPM ( 24 h SBP? 24 h DBP?dSBP?dDBP?nSBP?nDBP) and color echocardiography (IVST?PWT?LVMI)after treatment in the two groups were significant decreased compared with those before treatment respectively (P0.05). Conclusion Valsartan can lower significantly the blood pressure level and make left ventricular hypertrophy remarkably dispelled in hypertensive patients with left ventricular hypertrophy and has the effect similar to that of amlodipine.

Objective To evaluate the correlation between hyperlipidemia and lower limb arterial disease in eldedy diabetic patients with color Doppler uhrasonography.Methods Two hundred and sixty elderly diabetic patients and 206 normal subjects were enrolled in the study.Doppler uhrasonographic manifestations of lower limb arterial disease,blood pressure and blood biochemistry parameters including fasting plasma glucose(FPG),postprandial plasma glucose(PPG),TC,TG,HLD-C,LDL-C,apoprotein B (apoB),very low density lipoprotein cholesterol(VLDL-C),apoprotein Al(apoA1)and fibrinogen(Fb)were compared between the 2 groups.Results (1)The blood biochemistry parameters,including the levels of FPG,PPG,TC,TG,VLDL-C,LDL-C,apoB and Fb were higher in diabetic patients t11an in normal subiects.while HDL-C was lower(all P＜0.05).(2)The thickness of intima-media(IMT)in the lower limb arterial disease group was significantly increased and the presence of arterial stenosis and wall plaques more in diabetic patients[IMT in 205 cases(78.85%),atherosclerotic plaque in 241 cases(92.69%),muhivessel disease(more than 2 vessels)in 60 cases(23.08%)and arterial stenosis in 89 cases (34.23%)]than in normal subjects[IMT in 37 cases(17.96%),atherosclerotic plaque in 51 cases (24.76%),muhivessel disease in 27 cases(13.11%)and arterial stenosis in 3 cases(0.01%)],all P＜0.01.(3)Regression analysis showed that lower limb arterial disease was correlated with high level of LDLC and low level of HDL-C.Conclusions Arteriosclerotic plaque is one of the early manifestations in elderly diabetic patients and hyperlipidemia may provide the basis of its formation.Doppler uhrasonographic examination of lower limbarterial discloses the early arteriosclerotic changes of lower limb arterial disease in elderly patients and offers the basic data of indication for clinical treatment.

Objective To identify the risk factors associated with intraoperative acute cardiac decompensation in patients undergoing off-pump coronary artery bypass grafting (OPCABG). Methods From November 2007 to February 2009, 2379 OPCABGs were performed in our hospital. The possible risk factors associated with intraoperative cardiac decompensation were retrospectively analyzed. The preoperative patient demographics and intraoperative characteristics were correlated with intraoperative acute cardiac decompensation.The possible risk factors included sex, age, body weight, cardiac function (NYHA classification), the associated diseases (hypertension, diabetes mellitus, liver-kidney dysfunction), history of myocardial infarct, ventricular aneurysm, preoperative treatment with β-blocker and/or calcium channel blocking agent, ventricular extrasystole,atrial fibrillation, duration of operation, etc. Results Three hundred and sixty-eight patients developed acute cardiac decompensation during OPCABG (15.5%). No patient died during operation. Multivariate analysis indicated that the risk factors for acute cardiac decompensation during OPCABG included left ventricular aneurysm valvular dysfunction, left main disease, history of myocardial infarct, preoperative ventricular premature beat,preoperative ejection fraction (EF) ＜ 40%, intraoperative atrial fibrillation, intraoperative frequent ventricular premature beat, tachycardia before anesthesia and emergency OPCABG. Conclusion The risk factors for acute cardiac decompensation during OPCABG includ left ventricular aneurysm valvular dysfunction, left main disease,history of myocardial infarct, preoperative ventricular premature beat, preoperative EF ＜ 40%, intraoperative atrial fibrillation, intraoperative frequent ventricular premature beat, tachycardia before anesthesia and emergency OPCABG.
