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.

In this paper,the author introduced the features of online mendelian inheri-tance in man database,and intensively reviewed its application in teaching and research of medical genetics,thus providing teachers and scientists an updating dictionary.

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.

Background The retinal degeneration 11 (rd11) mouse is a newly discovered naturally occurring recessive animal model with lysophosphatidylcholine acyltransferase 1 (Lpcatl) mutation.Previous studies showed that the photoreceptor cells are characterized by typical rod-cone degeneration pattern in rd1 1 mice,while cone degeneration pattern in rd11 mice is unclcar.Objective Using immunofluorescence staining techniques with retinal wholemount,we aim to clarify the degeneration patterns of cone-function related M-opsin or S-opsin in different ages of rd1 1 mice.Methods A total of thirty rd1 1 and C57BL/6J mice at postnatal (P) day 14,28,42 (five in each age group) were sacrificed and retinal wholemounts were prepared.Immunohistochemistry was performed to identify the expression of M-opsin or S-opsin in retinal wholemounts,which were photographed with a fluorescent microscope.Cone opsins were compared between rd1 1 retinas and age-matched normal C57BL/6J retinas by manually counting the opsin positive cone cells in different quadrants of the retinas.Results The number of M-opsin or S-opsin positive fluorescent dots in each quadrant was similar at all ages of normal C57BL/6J retina.M-opsin positive fluorescent dots in dorsal/temporal,ventral/temporal,dorsal/nasal and ventral/nasal quadrants of rdl 1 retina at P28 were (414±32),(300± 8),(324 ± 22) and (250± 20)/0.037 mm2,which were lower than the age-matched normal C57BL/6J mice (t =4.114,15.225,7.505,17.990,all at P＜0.05).At the same time the S-opsin positive fluorescent dots in P28 rd11 were (8 ±4),(175 ± 16),(74 ± 13) and (315 ±20)/0.037 mm2,with significant decrease in comparison with those in the age-matched normal C57BL/6J mice (t =8.555,17.076,21.637,13.498,all at P＜0.05).With the development of retinal degeneration in rd11 mice,the M-opsin degeneration spread from central to ventral,nasal and then to temporal and dorsal peripheral retina;and the S-opsin loss started from dorsal/temporal to ventral/nasal retina.Conclusions Most of the M-opsin and S-opsins,especially the S-opsins in rd11 mice,degenerate in 6 weeks.Retinal wholemount and cone opsin immunofluorescent staining provide a useful tool to show the cone degeneration pattern and to evaluate the therapeutic efficiency in ongoing gene therapy study.

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.

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 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.
