Objective To explore the changes of asphyxial neonatal gastric juice pH values,and to provide data for making early intervention measures.Methods Eighty asphyxial neonates were divided into routine group(55 cases)and intervention group(25 cases).Twenty neonates who weren't asphyxial were set as a control group.Those neonates' gastric juice pH values were monitored dynamically.The newborns in intervention group were treated by giving smecta and cimetidine intravenously on the routine treatment.The impairment occurrence conditions of these newborns' gastrointestinal functions were observed.Results The gastric juice pH values of asphyxial neonates were obviously lower than those of the control group at their birth(Pa0.05).The occurrence rate of gastrointestinal functions impairment was lowered(?2=16.0 P

OBJECTIVETo explore the alterations of after depolarization and triggered activity in myocardiac muscle during progression of mouse aortic stenosis.

METHODSAfter the establishment of mouse aortic stenosis model, the heart was collected and intracellular potential was recorded using standard glass microelectrode. After the recording, the action potential (AP), early after depolarization (EAD), delayed after depolarization (DAD) in papillary muscles were analysed.

RESULTS(1) Compared with that of time-matched control mice, there were no changes of the action potoutial duration at 90% repolarization(APD90) in model mice at 2 and 5 weeks, whereas the APD90 was progressively prolonged at 9 and 13 weeks. (2) During the 30 minites of the experiment, spontaneous EADs and DADs were frequently present in medel mice at 9 and 13 weeks, were not in control and model mice at 2 and 5 weeks. (3) Compared with those of control group, EADs and DADs triggered by hypokalaemia or isoproterenol were increased significantly. The incidence rate of triggering EADs and DADs was progressively increased over time.

CONCLUSIONEAD, DAD and trigger activities increase gradually during the process of aortic stenosis, and it suggests that the myocardium electrical-instability is markedly increased in the insult hearts.

OBJECTIVETo find the characteristic parameters from electrocardiogram (ECG) which is most related to pathological progress, surface ECG was performed in mice at 2, 5, 9 and 13 week post surgery.

METHODSElectrocardiogram recordings: The mice were anaesthetized with tribromoethanol (250 mg/kg, i.p.). Lead II surface ECG were acquired by using the Biopac System MP150 at a rate of 5 kHz.

RESULTS(1) No arrhythmia was observed in Sham and 2-week Band mice. Spontaneous arrhythmias were observed in ECG recordings, with an incidence of 15%, 28% and 63% in 5-, 9- and 13-week Band mice, respectively. Tachyarrhythmias, such as frequent premature ventricular extrasystole, bigeminy, trigeminy, and paroxysmal tachycardia were found. (2) Analysis of ECG recordings revealed a significant prolongation of QT and QTc intervals. Compared with age-matched Sham mice, the increment in QT and QTc intervals was 20.4%, 32.7%, 49.7%, 61.0% and 27.1%, 32.1%, 43.9%, 59.1% at 2, 5, 9 and 13 week, respectively (P < 0.01). (3) The characteristic change in electrocardiogram was on the J wave. The amplitude of J wave was upward in Sham mice, and it was significantly flattened or inverted in Band mice. (4) Except that RR interval at 2 week showed a slight decrease, there was no significant change in PR interval and RR interval in Band mice.

CONCLUSIONIn the present study, we found that the increase incidence of spontaneous arrhythmias, prologation of QT interval and changes in the amplitude of the J wave in the surface ECG during progression of mouse cardiac hypertrophy and failure, and the progressive pattern indicated that a gradual aggravation of the ventricular repolarization delay in this mouse model.

0.05). TNF-? in group EK and EKM was lower than that in group E (P0.05). Conclusions Ketamine can inhibit the release of TNF-? caused by LPS and increase myocardial cAMP level, protecting myocardium from sepsis. This may be one of the anti-septic shock mechanisms of ketamine. Combination of midazolam with ketamine does not affect the anti-septic shock property of ketamine.

Objective To investigate the inhibition of low-dose aprotinin on systematic inflammatory response during cardiopulmonary bypass. Methods Twenty-eight ASA Ⅱ-Ⅲ patients(male 13, female 15) undergoing valve replacement were studied. The age ranged from 27 to 55 years and body weight from 37 to 70 kg. CPB time ranged from 66 to 218 mm and aortic cross clamping time from 30 to 140 min . The patients were divided into two groups: control group(n=14) and aprotinin group(n = 14) Premedication included intramuscular phenobarbital sodium 0.1 g and scopolamine 0.3 mg. Anesthesia was induced with intravenous midazolam 0. lmg/kg, fentanyl 20-30?g/kg and vecuronium 0. 1-0. 12mg/kg, and maintained with intermittent bolus injection of fentanyl and vecuronium supplemented with isoflurane inhalation. In aprotinin group aprotinin 1?106KIU was infused after induction of anesthesia until thoracotomy, after thoracotomy aprotinin was infused at a rate of 2.5? 106 KIU/h and aprotinin 2. 5 ?106KIU was added to the prime fluid as suggested by Levy. Blood samples were obtained before anesthesia, before CPB and 1h and 24h after CPB for determination of CD11b and CD18 expression on the surface of neutrophil by immunofluoresence flow cytometry. Results The expression of CD11b or CD18 and CPB time were positively correlated(?= 0.644, 0.538, P0.05). 1 h after CPB CD11b/ CD18 expression increased significantly in the control group and was significantly higher than that in the aprotinin group, but at 24h after CPB only CD11b expression in control group was significantly higher than that in aprotinin group. In aprotinin group there was no significant difference in CD11b/CD18 expression between the four intervals.Conclusions CPB-induced systematic inflammatory response may be positively correlated with CPB time. Low dose aprotinin can inhibit the increase in CD11b/CD18 expression after CPB.

Purpose To observe the curative effect of electroacupuncture in treating depression. Method Two hundred and ten subjects were randomly divided into electroacupuncture group and medication group. Results and conclusion The results were evaluated by an international depression scale in both groups. After one-course treatment, the average score markedly decreased in both groups, and a t-test showed that there was a significant difference in curative effect between before and after treatment in each group ( P < 0.001 ); but there was no such a difference between the two groups (P > 0.05 ).Electroacupuncture can be compared favorably with amitriptyline, an antidepressant. However, taking amitriptyline will produce some side effects. Therefore electroacupuncture is especially suitable for those who cannot take medicine.
