This paper reported the effect of captopril (SQ14225) on rabbits hemorrhagic shock. After late hemorrhagic shock model (MABP 40mmHg, maintained for 90min) was replicated, 26 rabbits were divided randomly into a captopril-treated group (n=13) and a control group (n=13). In the treated group, captopril(1mg/kg) was infused with normal saline (15ml/kg), low molecular dextran (15ml/kg)and shed blood, an hour later, the MABP, CVP and renal blood flow rose markedly, the platelet aggregation was significantly lowered and mesenteric microcireulation was improved remarkably. Three hours later, the various indexes mentioned above returned almost to normal (before the shock). The survival rate in 5 hours was 91.7%. The difference between the control and the treated group was quite significant (P

A mild rapid method for the determination of Pb in grain was established by diluted acid extraction and direct sampling detection with graphite furnace atomic absorption spectrophotometer(GF-AAS). Some factors, such as the grain size, nitric acid concentration, extraction time, solid, liquid proportion, and the instrument conditions were optimized. The results indicated that, at room temperature, the extraction rate of Pb in grain by diluted nitric acid was between 92. 14% and 94. 75%, and the average recoveries of Pb in grain extract reached 91. 65%-94. 58%, the precision of method was less than 5%, and the method detection limits and quantification limits were 0. 64 μg/L and 2. 14 μg/L, respectively, meanwhile, the extraction time was shorten to no more than 30 min. Compared with the results pretreated by microwave digestion and determined by GF-AAS, the detection values obtained by diluted acid extraction had no significance difference (p<0. 1).

Objective:Our purpose was to investigate the function of angiotensis converting enzyme(ACE) in the occurrence and development of pregnancy-induced hypertension(PIH). Methods:The study group included 30 pregnant women diagnosed with PIH( 10 mild, 10 moderate, 10 severe). Thirty healthy pregnant women were selected as the control group. The serum was assayed for the activity of ACE by using color comparison method, hippuric acid used as the substrate. Results:The activity of ACE of the study group was significantly higher than that of the control group. Significantly positive correlationships existed between mean blood pressure, degree of adema, level of urine protein,and uric acid. Conclusion:The elevation of serum activity of ACE is related to the occurrence and development of PIH.

Heart rate variability (HRV) is the difference between the successive changes in the heartbeat cycle, and it is produced in the autonomic nervous system modulation of the sinus node of the heart. The HRV is a valuable indicator in predicting the sudden cardiac death and arrhythmic events. Traditional analysis of HRV is based on a multielectrocardiogram (ECG), but the ECG signal acquisition is complex, so we have designed an HRV analysis system based on photoplethysmography (PPG). PPG signal is collected by a microcontroller from human's finger, and it is sent to the terminal via USB-Serial module. The terminal software not only collects the data and plot waveforms, but also stores the data for future HRV analysis. The system is small in size, low in power consumption, and easy for operation. It is suitable for daily care no matter whether it is used at home or in a hospital.
