0.05). Ac-cording to the classification criteria of ARIA in 2001, 26 children suffered from intermittent A(R22 mild cases,4 moderate-severe cases),while 22 suf-fered from persistent AR(10 mild cases,12 mod-erate-severe cases). Forty percent patients with AR also had bronchial asthma. Domestic decora-tion was an important factor in the induction of AR and 27.1% of the children with AR had inher-ent predisposition. CONCLUSION The prevalence rate of AR in children aged from 9 to 10 in Nanjing is 5.1 %. Strategy of prevention and treatment of AR should beworked out according to the epidemic feature of AR.

BACKGROUND: Both Allergic rhinitis and bronchial asthma are allergic diseases of respiratory tract. They frequently coexist in the same patients.OBJECTIVE: To study the incidence of allergic rhinitis in patients with bronchial asthma in Nanjing, and to analyze the correlation of clinical characteristic between allergic rhinitis and bronchial asthma.DESIGN: The questionnaire survey.SETTING: Department of Otorhinolaryngology-Head and Neck Surgery and Department of Respiratory, Nanjing General Hospital of Nanjing Military Area Command of Chinese PLA.PARTICIPANTS: A total of 134 patients with bronchial asthma including 73 males and 61 females were selected form Nanjing General Hospital of Nanjing Military Area Command of Chinese PLA from February 2001 to April 2005. Their ages ranged from 3 to 72 years. Severity of asthma of all patients was classified based on Global Initiative for Asthma (GINA). The diagnostic criteria of allergic rhinitis were established referred to the guideline of Haikou Meeting (November, 1997). All patients provided the confirmed consent.METHODS: The questionnaire survey of 134 bronchial asthma patients from the city of Nanjing was conducted. Their age, classification, severity, treatment status, and the family history of all 134 patients were investigated in details. Differences of age, age at onset, and course of disease between rhinitis and asthma of all patients were examined by two independent t tests. The correlation between clinical characteristics of allergic rhinitis and bronchial asthma was analyzed by Spearman rank correlation.MAIN OUTCOME MEASURES : Incidence of allergic rhinitis in patients with bronchial asthma and the correlation of clinical characteristic between allergic rhinitis and bronchial asthma.RESULTS:Of all 134 bronchial asthma patients,82(61.2%,82/134)were accompanied with allergic rhinitis.There were 45 males and 37 females.Of 82 patients with allergic rhinitis accompanying with bronchial asthma,severity was classified into grade Ⅰ (mild pause,n=56),grade Ⅱ (mild persistence,n=21),grade Ⅲ (moderate persistence,n=4),and grade Ⅳ (severe persistence,n=1).In addition,allergic rhinitis was classified into periodicity (n=65) and persistence(n=17).According to the classification and seventy system recommended in ARIA,63 patients had mild symptoms and 19 had moderate and severe symptoms.Severity of allergic rhinitis was positively related to that of bronchial asthma(r=0.689,P<0.01).CONCLUSION: The morbidity of allergic rhinitis combining with bronchial asthma is high in Nanjing, China. While, their classification and severity are highly coherent.

BACKGROUND:Chitosan is a kind of natural biomaterial and is characterized by great biocompatibility, progressive degeneration and absorption and excellent mechanical property; however, whether it may become an ideal cytoskeleton in the engineering of cartilage tissue or not should be researched further.OBJECTIVE: To observe the hydrophilicity and adsorptivity to human nasal septum chondrocytes and the effect of its function of a novel scaffold made by [poly (dl-lactide-co-glycolide)] (PLGA)/chitosan nonwoven cloth embedded with lecithin (LEC) and poly-L-lysine (PLYS).DESIGN: Blank control study.SETTING: Department of Otolaryngology-Head and Neck Surgery, Nanjing General Hospital of Nanjing Military Area Command of Chinese PLA.MATERIALS: The experiment was carried out in the Department of Otolaryngology-Head and Neck Surgery, Nanjing General Hospital of Nanjing Military Area Command of Chinese PLA from October 2005 to June 2006. Chitosan nonwoven cloth was provided by Hainan Xinlong Company. The mainly technical parameters were detailed as the follows: degree of deacetylation ≥ 90% and relative molecular weight 2-5 × 105. PLGA/chitosan nonwoven cloth scaffold was made in Department of Otolaryngology-Hean and Neck Surgery, Nanjing General Hospital of Nanjing Military Area Command of Chinese PLA and High Polymer Institute of Sun Yat-sen University. The mainly technical parameters were detailed as the follows: mole ratio between monome lactide and glycolide 75:25, porosity 82%-86%, pore diamater 100-300 μm, shear strength 48 MPa, depth 1.5 mm and completely degenerated duration 14-18 weeks. Human nasal septum chondrocytes were the septal cartilage of nose which was derived from operated patients with deflection of nasal septum under sterile condition.METHODS: PLGA/chitosan nonwoven cloth was sheared into pieces with the size of 1.5 cm × 1.5 cm, dipped in 0.01 volume fraction of LEC anhydrous alcohol and 1 g/L PLYS for 6 hours, dealt with ultraviolet radiation after dehydration for 1hour, dipped in 0.75 volume fraction of ethanol for 24 hours, washed with Hanks solution, and incubated for 24 hours. After operations mentioned above, two kinds of novel scaffolds containing various components were obtained, and they were simple scaffold and scaffold embedded with LEC and PLYS. Cells derived from the third generation of human nasal septum chondrocytes were used to make suspension. In addition, cell suspension was grown on those two scaffolds to determine the degree of hydrophilicity through observing diffused degree of cell suspension. Whether cell suspension of human nasal septum chondrocytes was wafted on scaffolds or not were observed under phase contrast microscope so as to determine adsorptivity between cells and scaffolds; meanwhile, growth of cells and production of matrix were also observed.MAIN OUTCOME MEASURES: ① Hydrophilicity of those two kinds of scaffolds (diffused degree of cell suspension of human nasal septum chondrocytes on scaffold) and adsorptivity to cells (whether cell suspension of human nasal septum chondrocytes was wafted on scaffolds or not); ② growth of cells and production of matrix.RESULTS: ① When simple scaffold was put in cell suspension of human nasal septum chondrocytes, cell suspension showing like balls attached to the surface of scaffold, and then, scattered into space of scaffold gradually. During the period of culture, phase contrast microscope indicated that masses of cells attached to the surface of fiber of scaffold.When the petri dish was shaken, cell groups drifted irregularly. The adherent rate was (21±3.7)%. With the cultured time passing by, matrix was not produced. ② When scaffold embedded with LEC and PLYS was put in cell suspension of human nasal septum chondrocytes, cell suspension scattered into space of scaffold rapidly. The adherent rate was (89±5.6)%, which was higher than that of single scaffold group. This suggested that scaffold showed a strong hydrophilicity.Phase contrast microscope indicated that chondrocytes as the form of monome or community were distributed between scaffold and fiber averagely and attached to the surface of fiber of scaffold. When the petri dish was shaken, cell groups did not drift irregularly, and only a few of cells were scarred at the bottom of petri dish. This suggested that scaffold had a strong adsorptivity to cells. One week after culture, matrix showing like cobweb was produced among fibers of scaffold.With the cultured time passing by, matrix was produced abundantly.CONCLUSION: The novel scaffold of PLGA/chitosan nonwoven cloth embedded with LEC and PLYS is characterized by an excellent hydrophilicity and adsorptivity to human nasal septum chondrocytes; meanwhile, it also can secrete matrix.

Objective To investigate the removal effect of immunoadsorption (IA) on associated antibodies and the efficacy in late-onset myasthenia gravis (MG). Methods A total of 25 late-onset MG patients were randomly selected to enroll in this study. IA therapy was given to 10 patients (IA group), while immunoglobin (0.4 g·kg-1·d-1) was administrated to the other 15 patients for 5 days(Ig group). The titers of Titin antibody (Titin-ab), acetylcholine receptor antibody (AchR-ab) and presynaptic membrane antibody (PrsmR-ab) were detected before and after the treatment. Quantitive MG (QMG) score was assessed before and immediately after the entire course of treatment. The clinical efficacy, the duration of respiratory support and in-hospital were compared between two groups. The correlation between three antibodies and QMG score was also analyzed. Results Compared with that before treatment, the Titin-ab PIN values, the AchR-ab PIN values, and the PrsmR-ab P/N values of IA group were all decreased significantly after treatment (P<0.05, respectively). The P/N value of Titin-ab in IA group was decreased by 54.7%~3.5%, which was significantly higher than that in Ig group(19.9%±3.1%) (P<0.01). QMG score reduced by 42.4%± 4.2% and 23.8%±3.7% in IA group and Ig group respectively (P<0.01, respectively). Symptoms were effectively ameliorated by both treatments, but the effective power of IA group was higher than that of Ig group (70% vs 40%, P<0.05). Remission time of IA group was significantly shorter than that of Ig group [(5.38±0.42) d vs (8.4±1.54) d, P=0.008), so was the duration of in-hospital [(13.50±0.50) d vs (16.50±0.50) d, P<0.05). The number of respiratory support in IA group was less than that in Ig group (1/10 vs 6/15, P<0.05). By the Pearson correlation analysis, the decrease of Titin-ab showed a better longitudinal correlation with the decrease of QMG score than the other two antibodies (r=0.6315, P<0.01). Conclusion IA can rapidly and effectively clear the pathogenic antibodies of late-onset MG patients and its short-term clinical efficacy is better than immunoglobin.
