Objective To determine the effect of mild hypothermia on neonatal piglet cardiac hemodynamic function after hypoxia-ischemia (HI).Method Twenty five 7-day-old piglets were used for hypoxic ischemic brain damage (HIBD) model by the method of temporary occlusion of the bilateral carotid arteries and followed by mechanical ventilation with low concentration of oxygen (FiO_2=6%) for 30 minutes.The piglets were randomly divided into three groups:group A (normothermia with body temperature to 39℃,n=9),group B (body temperature to 36℃for 72 hours,n=8),and group C (body temperature to 34℃for 72 hours,n=8).Mild hypothermia was initiated at 4 hours after HI,the systolic and diastole function were evaluated by Doppler echocardiography at pre-HI,post-Hi 4 hours and post-HI 72 hours.Results There were no significant differences in left ventrieular ejection time/left ventrieular ejection time (LPEP/LVEF),right ventricular ejection acceleration time/right ventricular ejection time (RACT/RVET) and CO at post-HI with hypothermia 72 hours in three groups,but the heart rate decreased in B and group C group.Compared with nonnothermia,mild hypothermia treatment showed no significant differences in MAP,LPEP/LVET,RACT/RVET,CO,SV at post-HI with hypothermia 72 hours.Conclusions Body temperature decreased by 3~5℃for 72 hours will not aggravate hemodynamic abnormity.

Objective To investigate the accuracy of three-dimensional reconstruction coronary angiography with CardiOp-B system in the evaluation of coronary artery stenosis, and make comparison with conventional quantitative coronary angiography(QCA). Methods The imaging data of 33 patients (39 vessel segments) who underwent coronary angiography and received interventional therapy were collected. The vessel diameter, vessel area, diameter of reference vessel rate of stenosed area and lesion length detected by three-dimensional reconstruction coronary angiography and QCA were compared. Results There was no significant difference in the detected minimal vessel diameter, minimal vessel area, diameter of reference vessel, rate of stenosed area and lesion length between three-dimensional reconstruction coronary angiography and QCA in these 39 vessel segments (P > 0.05), while the lesion length detected by three-dimensional reconstruction coronary angiography was significantly longer than that detected by QCA(P < 0.05). Conclusion Three-dimentional reconstruction of coronary angiography with CardiOp-B system demonstrates higher accuracy in the quantitative analysis of coronary artery stenosis compared with conventional QCA.

The culture medium and cultural conditions of solid-state fermentation of Streptomyces Menmyco-93-63 were tested in this study. The suitable medium which contains rice, sorghum, millet bran, and rice hull with the proportion of 2:2:3:3 was developed for the spore production of Streptomyces Men-myco-93-63 using single substrate screening, mixture substrate screening and orthogonal experiments, and the sporulation was up to 2.52?109 CFU/g. And then, initial charge, initial ratio of water to solid, inoculating quantity, and culture temperature impact to sporulation of Streptomyces Men-myco-93-63 were tested.
