Objective:To investigate the epidemic features of allergic rhinitis(AR)and correlative risk factors in Shihezi city,Xinjiang province,China. Method:A question-naire survey on AR and airway diseases was conducted among 2300 elementry school children in 12 schools,aged from 9 to 10 years old,from july 10 to 25,2008. in Shihezi city,Xinjiang province.Suspects of AR was identified by the survey,then they were recommended to specialist examinations for accurate diagnosis. Allergen skin tests were peformed to explore the allergenic varieties of allergic rhinitis. Diagnosis criteria of AR were that of ARIA(Allergic rhinitis and its impact on asthma). Resuit:Two thousand two hundred and eleven questionnaires were returned. The response rate was 96.1% and 2205 questionnaires were available.The prevalence rate of AR in children aged from 9 to 10 was 12.56%(277/2205) in Shihezi city.The difference of prevalence between female 13.76%(153/1112) and male 11.34%(124/1093) was insignificant statistically(χ~2=2.924,P＞0.05). The positive rate of the allergen skin test was 65.3%. The most common allergen of allergic rhinitis were plants of the mugwort and house dust mite. According to the ciassification criteria of ARIA in 2001,of 155 children suffered from intermittent AR,112 cases were mild and 43 cases were moderate-severe,while 122 suffered from persistent AR,110 cases were mild and 12 cases were moderatesevere. 5.4%(15/277) patients with AR also had bronchial asthma.25.3%(70/277) of the children with AR had inherent predisposition.Conclusion:The prevalence rate of AR in children aged from 9 to 10 in Shihezi city is 12.56%. Strategy of prevention and treatment of AR can be worked out according to the epidemical feature of AR.

Objective To explore the perioperative nursing of patients from high altitude earthquake-stricken regions. Method The perioperative nursing histories of 18 patients from high altitude earthquake-stricken regions were retrospectively analyzed to summarize the nursing experience.Results No wound infection,crush injury or complications occurred.Sixteen patients had good functional recovery,1 patient was at the stage of recovery about limb movement and another one was also at the recovery period from lumbar vertebral burst fracture complicated with nerve injury.Conclusion Close observation,psychological nursing and functional exercise are important for improved success rate of treatment for the patients from the earthquake-stricken regions.

BACKGROUND: Primary progressive aphasia(PPA) is a degenerative disease of nervous system, which is very rare in clinics. Only 3 cases have been reported in our country. There is very little clinical information regarding the characteristics of PPA in linguistics and imageology.OBJECTIVE: To report the language disorder and the characteristics of imageology of one PPA patient for the clarification of the clinical features of PPA.DESIGN: A case analysis.SETTING: Department of Neurology, Beijing Tiantan Hospital; Faculty of Psychology, Beijing Normal University.PATICIPANT: Male, 56 years old, senior high school graduate, businessman before the onset of the disease. The case visited the department of Neurology,Tiantan Hospital, Beijing due to the complaint of three years of progressive decreasing in language skills, which was then diagnosed with PPA.METH ODS: Spoken language fluency evaluation in Chinese Aphasia Examination Set of the First Affiliated Hospital of Beijing Medical University was used to evaluate this patient, the type of Aphasia was judged by Western Aphasia Examination Set, and the severity gradation was classified by the Boston Diagnostic Aphasia Examination(BDAE) . Memory, intelligence screening and imageology examination were performed as well.MAIN OUTCOME MEASURES: The fluency of spoken language, the type of aphasia, and the severity of aphasia of the patient were judged, and whether the patient suffered from memory and intelligence disorder were observed as well as the features of imageology.RESULTS: The patient had fluent spoken language, which was evaluated as sensory aphasia(SA) with the aphasia severity of level 4, and had no memory or intelligence disorder. MRI showed atrophy in left frontal lobe and temporal lobe, which was more significant in left side. MRI also showed that left temporal and frontal lobes had low metabolism and low perfusion.CONCLUSION: PPA is a disease with language disorder as its dominant clinical manifestation, which no other cognitive disorder at its initial stage,and with its main pathological changes in left temporal and frontal lobes.

Objective To investigate the amounts of endothelial progenitor cells(EPCs)in peripheral blood of patients with proliferative diabetic retinopathy(PDR).Methods Forty patients with PDR(PDR group),thirty patmnts with type 2 diabetes mellitus(DM)without DR(DM group),and twenty agematched normal subjects(control group)were enrolled in this study.Blood samples were treated bv repeated centrifugation and stained with monoclonal antibodies.At least 2 × 105 cells were analyzed bv flow cytometry.EPCs were identified by CD34 and CD133 antibody.The correlation between EPCs numbers and DR duration,glycosylated hemoglobin,serum lipids was analyzed.Results The number of EPCs in PDR,DM and control group were(49±12)、(35±11)、(90±25)cells/ml respectively,the difference was statistically significant(F=56.260,P=0.000).There was a positive correlation between EPCs numbers and DR duration(r=0.564,P＜0.05).However there was no correlation between EPCs numbers and glycosylated hemoglobin(r=-0.170,P>0.05)or triglyceride levels(r=0.261,P>0.05).Conclusions The number of EPCs in peripheral blood of PDR patients was decreased. EPCs might play an important role in the pathogenesis of PDR.

Objective To label human VEGF targeted bevacizumab (avastin) with 111In and to evaluate the application of 111 In?DTPA?avastin SPECT imaging for tumor diagnosis. Methods DTPA?avastin was prepared by coupling with a bifunctional chelating agent, and then labeled with 111 In to obtain 111 In?DTPA?avastin. The stability and molecular integrity of the labeled radiotracer were studied. Human hepatoma cell ( BEL7404) bearing nude mice tumor model was employed for tumor targeting evaluation. Gamma imaging was acquired after intravenous injection of 18.5 MBq probe. At the end of the observation, animals were sac?rificed for bio?distribution study. Results 111 In?DTPA?avastin tracer was synthesized and purified to a?chieve a radiochemical purity yield above 98% and specific activity up to 185 GBq/nmol. Its stability in 5%BSA was optimal, and the radiochemical purity after incubation for 96 h was over 90%. Gamma imaging re?sults showed that the tracer possessed definite tumor targeting property. Its biodistribution was consistent with that of normal in vivo antibody metabolism while possessing a good tumor?targeting property with a relatively high uptake of (3.8±0.8) %ID/g in tumor tissues 96 h after injection. Conclusions 111 In?DTPA?avastin tracer has good physicochemical properties, in vivo stability and good VEGF targeted binding. 111 In?DTPA?avastin has potential to be a new molecular probe for SPECT imaging.

ObjectiveTo investigate the effect of clinical pathway teaching methord in nursing practice teaching. Methods80 junior college nursing students were randomly divided into control and experimental groups. Traditional clinical teaching method was given to control group, while the clinical pathway teaching method was given to observation group. Scores of comprehensive quality after departmental rotation and satisfaction rates of nursing students to teaching method in these two groups were evaluated. ResultsThe experimental group was significantly better than the control group ( P＜0.05 ), and the difference was statistically significant. ConclusionThe clinical pathway can significantly improve the quality of nursing practice teaching.

Objective:To compare the models of guinea pig allergic rhinitis induced by different allergens. Methods: Ovalbumin (OVA), 2,4-tolylene diisocyanate (TDI) and alternariaalternata was respectively used as the allergens to establish the model of guinea pigs allergic rhinitis. The conformity of the models and human allergic rhinitis was studied through the behavioral indices, such as the times of nose itches, nasal discharge flow, histological properties and serum HA and IgE indices. Results:The times of sneezing and scratching nose, serum HA and IgE in OVA group was significantly different from those in the control group (P<0. 001 or P<0. 01). Conclusion:The models of allergic rhinitis induced by OVA are the same as allergic rhinitis in typical symptoms and pathological changes.
