ABSTRACT
Xingnaojing injection has been widely used in the treatment of cerebral vascular diseases, through the following mechanisms: improving the blood-brain barrier (BBB) permeability, anti-oxidant free radical damage, inhibition of excitatory amino acids (EAA) toxicity and calcium overload, inhibition of apoptosis, reducing cerebral edema and inhibition of autophagy. Thus, the paper summarized its progress.
ABSTRACT
ObjectiveTo study the teaching method of childbirth turning point and enhances teaching effect in the normal birth of the gynecology and obstetrics department teaching. MethodsAfter carting on the different form the teaching, to 382 students of Qujing medical high school, we carry on the one-to-one skill operation inspection and make the contrastive analysis of the achievement test scores of the students in the experimental group and the control group. Results There is remarkable difference between the conventional experiment teaching and the experiment teaching of adding giant pelvis ( P＜0.01 ). ConclusionThe giant pelvis's application can enhance the teaching effect enormously in the childbirth turning point teaching, and this method has the application and the promoted value.
ABSTRACT
Objective To investigate the effects of sustained nitric oxide (NO) inhalation during operation on neutrophil CD11b expression and postoperative lung function in patients undergoing cardiac valve replacement with cardiopulmonary bypass(CPB) .Methods Forty-two ASA Ⅱ or Ⅲ patients aged 35-53 yr weighing 47-69 kg undergoing cardiac valve replacement with CPB were randomly divided into 2 group:NO group(n = 21) and control group(n= 21) .In NO group the patients inhaled 40 ppm NO through the lungs and oxygenator after tracheal intubation during operation before the chest was closed. Anesthesia was induced with fentanyl 20 ?g?kg-1 and pipeceuronium 0.2 mg?kg-1 maintained with isofluarane inhalation and intermittern i.v. boluses of fentanyl and pipecuronium. A total of 5 000 000 IU aprotin was given during operation. Arterial blood samples were taken before induction of anesthesia (T0, baseline), immediately before CPB (T1 ) 10 rain after CPB was started (T2 ), immediately before aortic unclamping (T3 ) ,10 min after aortic unclamping (T4 ), at the end of operation (T5 ) , 12 h and 24 h after operation (T8 ,T9) for polylmorphonuclear(PMN) counts and determination of neutrophil CD11b expression . Blood gas analysis was performed PA-a O2 was calculated and dynamic compliance of respiratory system (Cdyn) was measured before induction of anesthesia, at the end of operation and at 4 and 8 h after operation. Results PMN count significantly decreased at T2 compared to baseline and then gradually increases ( P
