Acta Medicinae Universitatis Scientiae et Technologiae Huazhong 2001;30(3):221-223
The effects of immediate administration of inderal following acute myocardial infarction on left ventricular remodeling were studied in acute myocardial infarction model of the rabbit. The results showed that there was no significant difference in the infarct size and expansion index between the infarct-inderal group and the infarct-placebo group. As compared with sham surgery-inderal group,infarct-inderal group had a higher ventricular weight,left ventricular volume index and left ventricular wall stress [(2.65±0.17) g/kg vs (2.32±0.11) g/kg,P<0.05;(2.22±0.23) ml/kg vs (1.70±0.12) ml/kg,P<0.001;(0.84±0.07) vs (0.75±0.052),P<0.05,respectively],but there was no significant difference between the infarct-inderal group and infarct-placebo group. Heart rate in the infarct-inderal group was significantly decreased as compared with that of infarct-placebo group [(153±6.36) min-1 vs (225±4.08) min-1,P<0.001],but there was no significant difference in left ventricular end-diastolic pressure,+dp/dt max and cardiac index between the two groups. It was suggested that immediate administration of inderal postinfarction had no preventive effect on left ventricular remodeling.

Chinese Journal of Primary Medicine and Pharmacy 2009;16(4):623-624
Objective To study the outcome of pregnancy with lupus nephritis. Methods The clinical data of 9 pregnancies with lupus nephritis were retrospectively malyzed. Results Hypertension,proteinuria,injured renal function and abnormal serological marker were complicated with nine patients with lupus nephritis in pregnancy. The outcome of pregnancy was as following:abortion 2 cases,stillbirth 1 case,premature delivery 4 cases,term delivery 2 cases. All neonate survived without malformation. There was no postpartum hemorrhage or death. Patients with active SLE had very high fetal mortality( 100% ). And SLE got worsen in 50% of them. However,fetal mortality rate in pa-tients with controlled or quiescent SLE was 11.1% ,which was much lower than it in other patients(P<0.05). Con-clusion Lupus nephritis should be controlled before pregnancy. Pregnancy outcome could be improved by careful multidisciplinary monitoring and proper usage of adrenal cortical hormone.

Objective The mechanism of delaying flap with the minimal invasive surgery was approached to understand its effects on the whole delayed survival of skin flaps thoroughly so as to provide the rationale for its clinical use.Methods 80 male or female Wistar rats were randomly subdivided into two groups:delayed by the minimal invasive surgery,and immediately transfer without delay.Flaps in each group delayed were cut at 1,2,3 and 4 weeks,respectively.The flap was designed at the lower back of rat,with the size of 5 cm × 1 cm,crossing the middle area for 2.5 cm and including stem of iliac branch from iliolumbar artery.2 weeks after second operation,the survival area,capillary density and content of lactic acid of the flaps in each group were examined,and the survival of the falps delayed by the minimal invasive surgery was compared.Results The longer delaying time,and the higher survival rate were observed in the experimental group.Delaying for 3 weeks and 4 weeks,the survival rate was (86.13 ±1.13) %,(93.49 ± 1.15) %,respectively,in the experimental group.While in control group,the survival rate was no more than 63%.The longer delaying time,the higher the capillary density were noted in two groups,but 3 weeks delayed group equally matched to the 4 weeks delayed group.In the experimental group,the content of lactic acid increased peaked in 1 week delayed group,then fell-down gradually,but kept steady in 3 and 4 weeks delayed group.The content of lactic acid in the control group kept steady.Conclusions The experimental model is selected as cross-area axial flap on the lower back of rats.The minimal invasive surgery plays the same role as in delaying flaps,which causes vasoconstriction,resulting in disorder of internal environment,ischemia and hypoxia,finally vasodilatation.The more ramus anastomosis,the more survival rate of the flap.
