Objective To investigate a mechanism protected radiation-induce injure for radiated guinea pigs'nasal mucosa treated with intranasal corticosteroids (fluticasone nasal cavity spray). Methods 50 health guinea pigs were divided into 2 groups randomly: the irradiated group (control group) with 25 guinea pigs and the administration group after irradiation (test group)with 25 guinea pigs. The nasal part of all guinea pigs were performed irradiation by the 6 MV X-ray with single 5 Gy, one time each week for three weeks. The guinea pigs of test group received intranasai eorticosteroids with one time every day and one spray each side nasal cavity on the second day after three weeks irradiation. Five guinea pigs in each group were saeritieed randomly at 1 week, 1 month, 2 months, 3 months and 4 months after irradiation, and the histopathologie changes were observed under optical microscope and electron microscope. At the same time, blood were drawn from the heart and the concentration of IL-1, IL-6 and TNF-α in serum were measured by ELISA. Results The early nasal mucosa inllammatory reaction of the test group was less than the control group. The coverage rate of cilia of the test group was much than that of the control group (72.9% vs 50.2%) at four months after irradiation. The atrophy of submucosal glandular organ was lessened and they displayed some extent secretory function. The concentration of IL-1 in serum was increased very much in the test group compared with the control group after irradiation and kept higher level in the first two months. After two months, it began to decrease;on four months, it still kept equivalency level with the control group. The concentration of IL-6 and TNF-α in serum were reduced all the while. Conclusions The intranasal eortieosteroids with fluticasene nasal cavity spray can reduce radiation-induced injury of guinea pigs' nasal mucosa. The concentration change of IL-I, IL-6 and TNF-α in serum may be one of mechanism protected radiation-induce injure of guinea pigs' nasal mueosa.

Objective To study the influence of cilostazol to aspirin resistance in patients with coronary heart disease.Methods A total of 165 patients with coronary heart disease were set apart two groups:group A:coronary heart disease,group B:coronary heart disease by 2-diabetes mellitus,Both group A and group B received 100 mg of aspirin daily for 7 days and no other antiplatelet agent.The blood samples were analyzed by platelet aggregation(PAG)test.Platelet aggregation using adenosine diphosphate(ADP)and arachidonic acid(AA).then two groups were randomized four groups:A1,A2,B1,B2 separately.both group A1 and B1received aspirin 100 mg qd continuely,group A2 and B2 added anther antiplatelet drug cilostazol 50 mg bid,redetected platelet aggregation after a week.compared PAG and AR using statistic methods.Results PAG and AR of group A is lower than group B(P0.05).The PAG and AR of group A2 was significantly lower than group A and group A1(P0.05),the PAG and AR of group B2 is significantly lower than group B and group B1(P

Objective: To study shame of college student through phenomenological method. Method: 147 college students (male 53, female 94, average age 20.2) were involved. Each subject was asked to describe his/her personal shame experience, which was rate on phenomenological dimensions. Experience of Shame Scales (ESS) was used either. Result: The finding from phenomenological rating was in accord with the theory of “self orientation". Students with stronger shame proneness showed tendency to attribute negative events to him/herself. Conclusion: Shame is an acutely painful experience that involves a marked self-focus (self oriented) emotion. Shame proneness tended to have stronger sense of worthlessness and powerlessness and have much more strategies of denying and escaping in hard situations.

Preoperative qualitative diagnoses of 118 eases of renal tumour.made by B-mode ultrasound were analyzed.The final diagnoses were proven operatively and pathologically.The resultsshowed that by B-mode altrasound the detective rate was 92.2%,a correct qualitative diagnosis rate 49.1%,incorrect rate 18.1%and false positive rate 1.7%.Qualitatively unidentified turnouts accounted for 32.8%of all the cases.It is assumed that B-mode ultrasound can be used to make correct qualitative diagnosis only on certain tumours with typical image features.It is difficult for it to distinguish some tumours which have complicated displays.The accuracy of preoperative qualitative diagnosis could be raised by combining B-mode uhradound with other imaging technologicol examinations.

Methods 28 rabbits were randomly divided into 4 groups (control group, hypercholesterol group, Erchentang group, Xuefuzhuyutang group). The models were developed by fed high cholesterol diet, the changes of bulbar conjunctival microcirculation were detected at 10 weeks. Results Xuefuzhuyutang decreased the score values of the capsular dilatation, the diameter of microvein, the red blood cell aggregation (P

Objective To study the clinical effect of compound Yisui Shengxue Keli(YSSXKL) on treating ?-thalassemia. Methods By using self-control study method,30 cases of major and intermediate ?-thalassemia had been first treated with placebo for three months,then were treated with YSSXKL in the followed three months in Guangxi province,the high incidence area of the disease. The clinical symptoms,traditional Chinese medicine symptoms and dynamic changes of the blood levels of Hb,RBC,Ret and HbF were observed before and after each treatment. The CRF tables were filled in according to the traditional Chinese medicine symptoms of the patients and the side effects recorded. Results During period of placebo treatment,the main curtive effective indexes Hb and RBC were not obviously raised,while the RBC levels were inversely degraded after the first month of taking placebo orally(P

Objective To investigate the changes in heart rate(HR) after catheter ablation of atrial fibrillation(AF).Methods A total of 52 consecutive patients(mean age 64.65?10.18 years old) with symptomatic AF and no atrial tachycardia or AF recurrence during post-ablation follow-up were icluded in the study.Holter was performed to evaluate the changes in HR before the ablation,at one week and at one,three,six,and twelve months after the procedure.Results All the 52 patients received catheter ablation of AF successfully.The mean HR of all patients increased from 68.92?7.53 bpm at baseline to 75.58?6.48 bpm at one week after the procedure(P

Objective To analyze the distribution of key target sites(KTSs) during initial circumferential pulmonary vein isolation(CPVI) for atrial fibrillation(AF) and during re-ablation.Methods Forty eight cases(30 males,average age 54.3?10.2 years) with recurrent AF were enrolled.AF was paroxysmal in 24 cases and persistent in 24 cases.Re-ablation was performed 37.2?7.4 days after initial CPVI.KTS was defined as the target sites where pulmonary vein potentials(PVPs) delayed,conduction sequence changed,PVPs slowed down or PV isolated during ablation.Circumferential pulmonary vein(PV) lesions were divided eaqually into 8 segments.KTSs were analyzed during initial CPVI and re-ablation.Results One hundred and forty five KTSs were identified during initial CPVI.The mean KTSs per case were 3.02?1.08,compared with 1.58?1.09 during re-ablation,P

Objective To evaluate the electrophysiological mechanism of early recurrence of atrial tachyarrhythmias(ATa) after initial ablation for paroxysmal atrial fibrillation(AF)and the feasibility of early re-ablation.Methods Forteen cases(8 males,average age of 61.8?8.4 years) presented with early recurrent ATa within 1 month after initial ablation were included.Early recurrence was observed after a mean of 4.9?3.7 days post-ablation.During re-ablation,all pulmonary vein(PV) reconnection was re-isolated,and AF induction was applied to map and ablate non-PV triggers.ECG and Holter monitor was applied to evaluate the effect.Results Re-ablation was performed after a mean follow-up of 24.7?5.5 days after the first ablation.PV re-connection was identified in 13 cases(92.9%) and was re-isolated by closing conduction gaps along initial lesion lines.By AF induction,superior vena cava(SVC) originated AF was detected in 3 cases and was terminated by SVC isolation.Upper crista terminalis(CT) foci was found in 1 case which was eliminated by focal ablation.Typical atrial flutter(AFL) in 3 cases and left atrial AFL in 1 case were terminated by linear ablation.At the end of follow-up of 5.8?1.4 months,13 cases were free from ATa recurrence and anti-arrhythmic drugs.Paroxymal ATa was observed in 1 case which could be suppressed by verapamil.Conclusion PV re-connection is the main influencing factor of early recurrence of ATa after initial ablation for paroxysmal AF.Other factors include foci located in SVC and CT.Early re-ablation is feasible and effective.

Objective To investigate the prevalence of aspirin resistance(AR)in the patients with metabolic syndrome and the clinical characteristics.Methods A total of 221 patients with metabolic syndrome received 200 mg of aspirin daily for 10 days and no other antiplatelet agent.The blood samples were analyzed by platelet aggregation test(pAgT)using arachidonic acid(AA).We identified aspirin resistance when arachidonic acid induced aggregation≥20%.Results 17.6%of the patients showed AR.The AR fibrinogen level was significantly higher than AS patients(2.6?0.4 vs 2.4?0.4,P=0.017).Patients who were AR had no statistically significant difference in blood pressure,age,fasting blood glucose,blood fat and BMI compared with aspirin-sensitive patients(AS).There was also no difference in sex,smoking and history of myocardial infarction or ischemic stroke between AR and AS patients.When stratified by sex,we found history of myocardial infarction was predictor for AR in male(50.0% vs 14.5%,P=0.020)and so was diastolic blood pressure higher than 85mmHg in female(34.0% vs 15.5%,P=0.043).Conclusion The AR accounts for 17.6%(39/221)of all.In this research.AR patients have higher level of fibrinogen than AS.History of myocardial infarction and higher level of diastolic blood pressure may be the predictor for AR in male and female individually.
