Objective To explore a brief regimen to treat and manage asthmatic patients.Methods 122 asthmatic patients(including 12 inpatients) treated and managed at respiratory clinic were followed up for 1~10 years.The data of these patients were collected and analysed Results On the base of asthma education patients were received inhaled glucocorticoid combined with ? 2 agonist and/or theophylline for two to five years Of 122 patients,20(16 4%) patients remised and remained good control without any medication,90(73 8%) patients relapsed within 1 to 2 years after drug withdrawal Conclusions Asthmatic patients must be treated and managed regularly according to GINA It was especially emphasized that inhaled glucocorticoid is the mainstay of ling term threapy Most patients can remise for quite a long time with agreeable quality of life while a few patients can be cured

Objective:To probe into the long-term effect of La(NO3)3 fed orally on gast ric mucosa of rats.Methods:The gastric mucosa of rats was studied after La(NO3)3 was administe red orally for a long-term,by the use of ordinary histological technology and m orphometry.Results:In the groups of 20 mg·kg-1 and 10 mg·kg-1,the cytopl asma of more parietal cells lying in the top of the gastric gland was loose.Proporti on of cell types of the gastric gland was related to the doses. The acid mucus l evel of the mucous neck cells of male rats in the groups of 20 mg·kg-1 an d 10 m·kg-1 decreased. In the groups of 2 mg2kg-1, 0.2 mg·kg -1 and 0.1 mg*kg-1,the acid mucus level of the mucous neck cells of both male and female rats increased.Conclusion:La(NO3)3 fed orally for a long-term could injure gastric muc osa in higher dose (20 mg·kg-1,10 mg·kg-1) but promote the protect ive action of the gastric mucosa in lower dose (0.2 mg·kg-1,0.1 mg·kg- 1).

Purpose The aim is to establish the HPLC method for the determination of Fluoro-deoxyuridine in plasma.Methods The Chromatography conditions include: Chromatography column: Nova-pak C18(3.9mm×150mm,4μm), mobile phase: 0.05mol/L sodium phosphate monobasic -methanol-water(0.5∶7∶92.5), UV detection at 260nm, FUDR was extracted with ethyl acetate. Results The average recoveries were 96.4%,96.5%,97.8% for concentration 0.23、1.67、20.0μg/ml (n=5).The corresponding reproducibility were RSD 1.61%, 1.98%, 3.17% respectwely for iner-day and RSD 3.56%, 1.90%, 2.63% for the intra-day(n=5). The FUDR concentration was linear with a correlation coefficient of 0.999 4 over the range of 0.099~20.0μg/ml. Conclusion The method was sensitive and accurate and suitable for pharmacokinetics and bioavailability study of FUDR.

Objective To give an empirical study on the interests claims of employees in public hospitals. Methods By questionnaire investigation, to sum up data using factor analysis and pairedsamples T test, and to compare difference between different kinds of patients using ANOVA. Results The interests claims of employees can be summed up to seven factors and there is some significant difference between different kinds of employees. Conclusion At current stage, public hospitals need pay more attention to material interests claims of employees.

Objective To investigate the clinicopathologic characteristics of and HPV subtypes in vulvar condyloma acuminatum(CA)and subclinical HPV infection.Methods Eighty patients with a positive acetowhite test and suspected subclinical HPV infection were selected from 272 patients with typical CA lesions in perianal and external genital region.Tissue specimens were obtained from typical CA and suspected subclinical HPV-infected lesions followed by pathological examination and HPV-DNA detection.Finally,71 patients were confirmed to suffer from both CA and subclinical HPV infection.A comparative analysis was performed to assess the differences in histopathological manifestation and HPV genotypes between CA and subclinical infection lesions.Results Pathological examination revealed typical histological changes of CA in 71(88.75%)typical CA specimens and 4(5%)suspected subclinical infection specimens,as well as squamous dysplasia in 9(11.25%)CA specimens and 71(88.75%)suspected subclinical infection specimens.HPV-DNA was positive in all(80)of the CA specimens and 93.75%(75)of the suspected subclinical infection specimens,negative in 5(6.25%)suspected subclinical infection specimens.Obvious differences were observed in pathological manifestation,koilocyte number(P < 0.05),but not in the distribution of HPV subtypes(P > 0.05),between typical CA and concurrent subclinical HPV infection lesions in patients.Conclusion The diagnosis of subclinical HPV infection should be based on the result of acetowhite test,with the results of pathological examination and HPV DNA detection as an adjuvant.

Objective To investigate the histological changes of rapid tooth movement in dogs treated by resistance reduction and distraction osteogenesis, aiming to establish an animal model and further to reveal the remodeling mechanism of rapid tooth movement. Methods A total of 8 local hybrid dogs were selected as subjects for this study. The second pre-molar was extracted on both sides. The experimental side underwent alvelor surgery for resistance reduction and a home-made tooth-borne intraoral distraction device was installed for rapid tooth movement, while for the other side (control side) only tooth-borne intraoral distraction device was used for rapid tooth movement. The longest active force-delivery span was 2 weeks, followed by 6-week retention. The distance between the moved tooth and anchor unit was recorded weekly, and radiography was performed for each side before and after distraction. The surrounding tissues including periodontal ligament and alveolar bone were sectioned for histological analysis. Results The average distance of tooth movement was 3.55mm on the experimental side and 1.11mm on the control side. The rate of tooth movement was notably higher (P<0.01) and no significant apical root resorption was detected by X-ray on the experimental side. The active alvelor bone remodeling was found on the tension and pressure sides. However, there was no significant difference between the experimental side and the control side after the retention period. Conclusion The rate of orthodontic tooth movement can be accelerated through resistance reduction and periodontal distraction without any unfavorable effects but at minimal anchorage loss.

Aim To investigate the effect of CD44 anti-body-A3 D8 on the expression of IL-3 Rα and down-stream PI3K/Akt in NB4 cells. Methods The ex-pression of IL-3 Rα mRNA was detected by real-time quantitative RT-PCR, the IL-3Rα protein expression and changes of PI3 K/Akt signal pathway in NB4 cells treated with A3D8 were analyzed by Western blot. An-nexin-V-FITC/PI double staining flow cytometry was u-tilized to detect the apoptotic cells. The inhibitor of PI3 K/Akt signaling LY294002 combined with A3 D8 was used to inhibit the PI3K/Akt in NB4 cells. Re-sults After treated with A3 D8 , both the transcription-al level and translational level of IL-3 Rα were remark-ably reduced, and the PI3K/Akt pathway was inhibi-ted. LY294002 improved the inhibitory and apoptotic effects of A3D8 on NB4 cells. Conclusion CD44 antibody A3 D8 can downregulate the expression of IL-3Rα and inhibit the downstream PI3K/Akt pathway.
