Basic & Clinical Medicine 2006;0(12):-
asthma is a kind of chronic mucosal inflammation and characterized by eosinophilia,hypertrophy of goblet cell,increment of mucous secretion,reversible airway obstruction and hyperresponsiveness to external and endogenous stimuli.Of them,the recruitment and activation of eosinophil have an important role in the pathogenesis of asthma;the aim of this paper is to review the advancement of recruitment of eosinophil in the pathogenesis of asthma,and make a new method for the treatment of asthma.

Basic & Clinical Medicine 2006;0(04):-
Objective To find the best methods to make the extraction of alternaria alternate. Methods Alternaria alternate was harvested from air and identified, cultured at 26 ℃ for four weeks. Protein was extracted by different methods and its concentration was determined using the Bradford assay, its bioactivity was tested by RAST inhibition, and residual proteins were analyzed by SDS-PAGE.Results The extraction methods like grinder(a), grinder plus ultrasonic(b), ground with liquid nitrogen(c) and liquid nitrogen plus ultrasonic(d) were applied in the extraction procedure. The concentrations of protein extractions were as follows (g/mL): a was 0.44?0.04;b was 0.75?0.03;c was 0.72?0.03 and d; 1.29?0.05. From SDS-PAGE, we found that the most component in the extraction was that obtained by liquid nitrogen plus ultrasonic. From RAST, 50% inhibition was as follows(g/mL): a was 8.5, b was 9.4, c was 7.0,d was 3.7. Conclusion Ground with liquid nitrogen plus disintegration by ultrasonic was the most effective method of extraction.
4.Effects of procainamide on ventricular fibrillation in a canine model of sudden coronary death
Chinese Journal of Pathophysiology 1986;0(03):-
A canine model of sudden coronary death was established by intimal sur-face anodal direct current stimulation of the left circumflex coronary artery (LCX)on 5-8 days after the left anterior descending coronary artery (LAD) infarction. TheLCX intimal injury and subsequent thrombus formation produced ECG ST segment chan-ges at 104?30 minutes (X?SD), followed by premature ventricular beats, ventriculartachycardia (VT), and ventricular fibrillation (VF) in all normal saline (NS) treated dogs(n=6), in procainamide (PA) treated dogs (n=6), ECG ST segment changes appearedat 110?40 minutes, followed by VT and VF in only one dog (P

Objective To evaluate the value of MR-guided neurolytic celiac plexus block(NCPB)for treatment of upper abdominal cancer pain.Methods 13 neurolytic celiac plexus blocks were carried out in 12 patients with severe upper abdominal pain caused by malignant tumors.The pain-relieving effect of the block was both evaluated using visual analogue scale(VAS) and analyzed statistically in all cases.Results The placement of the needle MR-guided was easy and accurate,the successful rate of the puncture was 92%.There were no severe complications.The pain before and after the procedure had obvious difference and the pain relief could last for a long time.Conclusion MR-guided NCPB is a simple and effective technique for treatment of upper abdominal cancer pain.

ObjectiveTo analyze the dead reasons in treatment of acute myocardial infarction (AMI) by emergent percutaneous coronary intervention (EPCI) during perioperation. Methods The clinical characteristics of the dead patients,results of EPCI and reasons of death were retrospectively analyzed in 473 patients with AMI who received EPCI treatment during March 2004 to March 2011. ResultsAmong the 18 cases(3.8%)dead patients,there were 8 case with three-vessel lesions,5 cases with two-vessel lesions, 2 cases with single vessel lesion and 3 cases with left main lesion. Nine patients were accompanied with hypertensions,5 cases with diabetes mellitus, 1 case with old myocardial infarction, 2 cases with old cerebral infarction, 1 case with chronic obstructive pulmonary disease complicated by severe pneumonia, and 1 case with chronic renal insufficiency. Nine patients died of cardiogenic shocks , 4 cases (22. 2%) of heart ruptures, 2 cases (11.1%) of noreflow,1 case (5.6%) of massive hemorrhage of the upper alimentary tract, 1 case (5.6%) of respiratory failure and 1 cases (5.6%) of refractory ventricular fibrillation.ConclusionsPrimary reasons for perioperative death were cardiac shock and heart rupture in treatment of acute myocardial infarction by EPCI. Multi-vessel lesion, complications with hypertensions and diabetes mellitus may serve as succumbed factors of death.

Objective To compare the effects of tracheal intubation (TI) and laryngeal mask (LM) during general anesthesia (GA) induction on the α 1-band of quantitative pharmaco-electroencephalography (QPEEG).Methods Fortypatients undergoing GA were randomly divided into two groups:group T included 20 patients who received TI and group L included 20 who received a LM.Parameters like heart rate (HR),mean arterial pressure (MAP),and QPEEG were recorded before anesthesia induction (T0),after induction (T1),and after intubating the cannula or LM (T2).Using power-spectrum analysis,we calculated the power percentage of the α 1-band of QPEEG.Results The HR,MAP,and power percentage of the α 1-band in most areas of the brain were lower at T1 than at T0 (P < 0.05) in both groups.Moreover,the HR,MAP,and α 1-band power percentage were higher at T2 than at T1 (P < 0.05) in group T,whereas they showed no significant change at T2 (P > 0.05) in group L.Conclusion TI is stronger than LM for stimulating the circulatory system.Moreover,TI may cause an increase in the power percentage of the α 1-band of QPEEG.This finding suggests that the α1-band power percentage of QPEEG can be an effective means of monitoring stimulation.

A canine model of electro-physiologic-electropharmacologic testing on ischemic ventricular tachyarrhythmias were established in the open-chest dogs subjected to programmed electrical stimulation (PES) on 5~8days after acute my-ocardial infarction produced with two -stage occlusion of left anteriol decending coronary artery (LAD) followed by partly reperfusion. The electrophysiologic -electropharmacologic effects of pro-cainamide (PA ) were observed in this canine model. pA distinctly lengthened the QTc interval and the effective refractory period ( ERP) of normal and infarct myocardium in both ventricles and decreasedthe dispersion of ERP in infarct myocardium (IDR) as well as the dispersion of ERP in left ventricle (VDR). The PES - induced ventricular tachycardia (VT) or ventricular fibrillation (VF) was prevented in 5 out of 6 PA treated dogs (n = 6),Normal saline (NS) did not prevented PES- induced VT/VF. The results suggest that PA may be effective in preventing the onset of reentrant ventricular tachyarrhythmias after myocardium ischemic damage.

OBJECTIVE:
To investigate the prospective efficacy of chronic sinusitis lost to short-term follow up after nasal endoscopic surgery and the influential factors.
METHOD:
Prospective efficacy of 153 chronic sinusitis (CRS) was evaluated . All cases were treated by nasal endoscopic surgery at least 1 year ago but lost to follow up within 3 months after surgery. The clinical data of 153 patients were analyzed, including gender, age, educational level, course of the disease, smoking and drinking history, early surgery history, allergic rhinitis (AR) history, nasal polyps, visual analogue scale (VAS) score, nasal endoscopy score, CT examination score, the endoscopic experience of surgeons, medication of intranasal glucocorticoid and nasal irrigation after surgery. Multifactor logistic regression analysis were used to analyze the data.
RESULT:
Among 153 patient, the symptoms of 32 cases (20.9%) were completely control, while those of 74 cases (48.4% ) were partially control, and the symptoms of 47 cases (30.7%) were not controlled. The curative effect were better for CRS without nasal polyps, AR or early surgery history, with CT examination score < or = 5, operated by surgeons with experience of endoscopy surgery for more than 5 years. and treated with intranasal glucocorticoid for more than -1 weeks after surgery.
CONCLUSION
Postsurgery follow-up should be paid more attention to in treatment of CRS. Plans of follow up should be adjusted to patients condition. Treatment of postoperative sinus cavity should be minimized when the lesion is slight and operated properly.
