Objective To establish an animal model for immunological contact urticaria in mice.Methods A total of 60 BALB/c mice were randomly and equally divided into 5 groups:anti-dinitrophenol IgE monoclonal antibody (anti-DNP IgE) + 2,4-dinitrofluorobenzene (DNFB) group and anti-DNP IgE + trimellitic anhydride (TMA) group both injected with anti-DNP IgE via tail veins firstly,followed by topical treatment with DNFB and TMA respectively on the ears at 24 hours after the injection,DNFB group,TMA group and normal saline (NS) group all injected with NS via the tail vein firstly,followed by topical treatment with DNFB,TMA and NS on the ears 24 hours after the injection.In the following 14 days,mice were observed daily for the appearance of wheals and for scratching behavior.All the mice were sacrificed at the end of the study followed by determination of the percentage of degranulated mast cells and spleen index as well as observation of pathological changes.Results Wheals were observed in all the mice (12/12) in the anti-DNP IgE + DNFB group,some mice (8/12) in the anti-DNP IgE + TMA group,but not observed in any mice in the other 3 groups.Compared with the NS group,both the anti-DNP IgE + DNFB group and anti-DNP IgE + TMA group showed a significant increase in the percentage of degranulated mast cells (70.21％ ± 26.01％ and 54.25％ ± 39.57％ vs.14.45％ ±6.79％,F=14.41,P=0.000),spleen index (7.54 ± 1.56 and 7.87 ± 1.18 vs.5.37 ± 1.16,F=4.29,P=0.004) and scratching frequency ((31.58 ± 3.58)/h and (22.17 ± 3.81)/h vs.(2.00 ± 0.85)/h at 30 minutes,F =437.86,P ＜ 0.01).Conclusion A stable mouse model for immunological contact urticaria can be established quickly by sensitization with anti-DNP IgE and challenge with DNFB.

Objective To study community morbidity of gastroesophageal reflux cough (GERC),and then establish its procedure of diagnosis. Methods For the patients with chronic cough, on the basis of inquiring medical history and physical examination, chest radiograph, induced sputum, pulmonary ventilation function and airway hyperresponsiveness, blood eosinophilic, IgE,allergens skin test, nose, throat examination,sinus X-ray or pharyngoscope etc was managed. On the basis of the results,patients suspecting GERC was screened out, and then RDQ was performed, extra-esophageal symptoms related performance was inquired and scores were recorded. The patients with scores ≥ 12 were diagnosed as GERC; the patients with scores ＜ 12 were performed diagnosing treatment with proton pump inhibitor (PPI),and patients with positive results were diagnosed as GERC. The materials was analyzed statistically. Results The patients with chronic cough were 430 cases,and the community morbidity of GERC was 22.79%(98/430). RDQ ≥12 scores was 68.37%(67/98),and RDQ ＜ 12 scores was 31.63%(31/98).There was significant difference in extra-esophagus manifestation (P ＜0.01);26 cases with RDQ ＜12 scores were diagnosed as GERC (83.87%),and the rate of GERC in chronic cough was 21.63% (93/430). Conclusions RDQ is a favourable screening test in diagnosing GERC. PPI diagnosing treatment has high sensibility in GERC. It is necessary to establish community diagnosis procedure.

Objective To explore the effects of rhythmic auditory stimulation on the gait of patients with Parkinson's disease(PD). Methods Eight patients with PD and six healthy control subjects were studied.All subjects walked as usaal for 2 min and then Walked for 2 rain with rhythmic auditory attentional stimulation with a frequency 10% faster than their basic pace.The gait parameters in the two walking conditions were measured with three-dimension motion analysis equipment.In addition,executive function was evaluated using a frontal assessment battery (FAB)scale and the Stroop-3 test. Results In both walking conditions,average stride length and velocity were significantly lower in the PD patients than among the controls.The metronome at the higher frequency increased the cadence and stride velocity significantly in the controls.but in the PD patients it was associated with increased ca dence but decreased stride length.With auditory stimulation,the variability of velocity decreased significantly in the controls,but the variability in stride length increased significantly in the PD patients.Even with the auditory stimulation,the variability in step length,stride length and velocity were still significantly higher in the PD patients than among the controls.Executive dysfunction was clearly evident in the PD patients.Stroop-3 error rates were significantly negatively correlated with step length in the condition involving auditory stimulation.Conclusion Auditory attentional stimulation at a higher frequency becomes a new cognitive load for PD patients,and it cannot improve their gait.This may be related to executive dysfunction.

Objective To explore the effects of extrinsic and intrinsic recognition loading on gait in patients with Parkinson disease.Methods Eight patients with Parkinson disease and six control subjects were instrutted to walk with extrinsic and intrinsic recognition loading respectively.The gait parameters in two conditions were measured with three-dimension motion analysis equipment.FAB scale and Stroop Test were used as the evaluation of executive function.Results The velocity(cm/s),the cadence(step/min),single support and swing phase(%)in the audition stimulates condition in the patients group((113.4±14.32)step/min,(78.90±16.35)cm/s,(40.50±2.58)%,(40.50±2.58)%)were significantly better than those in the calculation condition(respectively(91.27±15.54)step/min,(63.79±21.49)cm/s,(37.95±2.61)%,(37.95±2.61)%).In the calculation condition,the coefficients of variability in stride length,swing and sinfle support phase were significantly higher in the patient group(respectively(6.69±3.99),(8.56±5.69),(8.56±5.69))than in thecontrol group(respectively(3.23±1.34),(5.02±2.54),(5.02±2.54));in the audition condition,except that,the coefficients of variability in step length and velocity also were significantly higher in the patient group(respeetively(11.92±5.86),(6.89±4.98))than the control group(respectively(7.35±3.32),(2.5±1.53)).In the patients group,the score of FAB(15.63±1.51)was lower and error rates of Stroop test(0.087±0.056)was higher than those in the control group(respectively(17.67±0.52),(0.027±0.03))significantly.The error rate of stroop-3 was significantly negative correlated with the gait variables of patient group in the calculation condition.Conclusion The extrinsic audition stimulates has lower effect on the gait of patients of Parkinson's disease than the intrinsic recognition loading.

Objective:To analyze the mechanism on integration of health care services at the county and town-ship level from the perspective of stakeholder theory. Methods: The stakeholder interest demand was determined by word frequency analysis of interview data from stakeholders in the three regions of Qianjiang, Huangpi, and Zhen-jiang;the degree of attention and gains and losses of stakeholders towards various demands was investigated from the three regions through interest demand questionnaires;the impact of demand benefits on behavioral responses has been evaluated through comprehensive evaluation theory and game theory. Results:Regional integration policies reflect the interest demands of stakeholders in varying degrees; the higher were the scores of demand benefits in interest de-mands questionnaires, the stronger was the willingness of stakeholders to coordinate integration policies. Conclusion:The policies of integration of health care services in rural China should consider all stakeholder interest demands;the better the interest demands of the stakeholders are satisfied, the stronger their motivation for integration reform will be, which may affect the implementation effects of local integration reforms to some extent.

Objective To explore the molecular mechanisms of primary amenorrhea by using arrayCGH technology. Methods Ten patients with primary amenorrhea and 10 female volunteers with regular menstrual cycles as healthy controls were selected. All patients and control samples were analyzed by conventional chromosome analysis (G-banding technology) and array-CGH technology, respectively. ArrayCGH was performed using Affymetrix Cytogenetic 2. 7M arrays following the manufacturer's standard protocol. Results Both the patient group and control group analyzed by conventional G-banding karyotype technology showed a negative result with a normal female karyotype: 46, XX. The result of array-CGH analysis demonstrated a microdeletion of approximately 110 000 bp located at the end of the short arm of X chromosome [46, X, del (X) (p22. 33 )] were identified in 5 patients, which was not detected in the control group. All healthy control samples by array-CGH analysis showed no pathological DNA copy number variation. Conclusions Array-CGH technology can improve the diagnosis rate of chromosomal disease at the DNA level. It is necessary to provide array-CGH for higher resolution genetic analysis of idiopathic primary amenorrhea patient who can not be identified by conventional technology.
