Objective To analyze the clinical data of 20 young and middle-aged patients with bronchial foreign bodies who were hospitalized because of unknown lung shadow. Methods The clinical data of 20 confirmed cases, including history of aspiration, imaging examination results, bronchoscopy findings and therapeutic process were retrospectively analyzed. The outcome of bronchial foreign body granuloma in the airway was observed. Results ⑴100%of the 20 patients with an average age of (46.39±3.26) years were misdiagnosed before bronchoscope examination. (2) The results of chest CT showed that the 20 patients had bronchial stenosis or obstruction with pulmonary consolidation or atelectasis, of which 18 cases were on the right side and 2 on the left side. (3) According to the shape and size of the foreign bodies as well as the length of time of aspiration, the bronchial openings were blocked by foreign bodies in 10 patients, and the foreign bodies were taken out by foreign body forceps. The diagnosis was confirmed in 3-6 (average 4.40±0.92) months in 10 patients. Four patients were obstructed by foreign bodies and granulation tissue, which took 5-12 (average 8.25±2.86) months to diagnose, while in 6 cases, masses were found in tracheal cavity, which took 6-15 (average 10.17±2.85) months to diagnose. The latter 10 (4+6) patients were treated with endotracheal intubation to remove foreign bodies and granulation tissue. (4) After 24-72 hours of treatment, the symptoms of cough, expectoration and blood in the sputum were relieved, and no severe complications occurred in 20 patients. (5) About two weeks after bronchial foreign bodies were removed, the granulation tissue disappeared. Conclusion Foreign body aspiration on the right side is more common in the 20 young and middle-aged patients, and bronchoscope is the best means of diagnosis and treatment.

A double targets of high throughput screening model for xanthine oxidase inhibitors and superoxide anion scavengers was established. In the reaction system of xanthine oxidase, WST-1 works as the probe for the ultra oxygen anion generation, and product uric acid works as xanthine oxidase activity indicator. By using SpectraMax M5 continuous spectrum enzyme sign reflectoscope reflector, the changes of these indicators' concentration were observed and the influence factors of this reaction system to establish the high throughput screening model were studied. And the model is confirmed by positive drugs. In the reaction system, the final volume of reaction system is 50 μL and the concentrations of xanthine oxidase is 4 mU x mL(-1), xanthine 250 μmol x L(-1) and WST-1 100 μmol x L(-1), separately. The Z'-factor of model for xanthine oxidase inhibitors is 0.537 4, S/N is 47.519 9; the Z'-factor of model for superoxide anion scavengers is 0.507 4, S/N is 5.388 9. This model for xanthine oxidase inhibitors and superoxide anion scavengers has more common characteristics of the good stability, the fewer reagent types and quantity, the good repeatability, and so on. And it can be widely applied in high-throughput screening research.

In order to improve the efficiency of drug screening on serotonin transporter (SERT) inhibitors, a high-throughput screening (HTS) model is established in RBL-2H3 cells. The RBL-2H3 cells are very similar to the serotonin genetic neuro, in modulation of post-receptor mechanisms and transduction pathway of SERT reactivated. Depending on a fluorescence substrate ASP+ used in detection method of inhibitor rates, it's convenient, quick, accurate and effective, not making the environmental biohazard compared with radioactive experiments. Furthermore, biological screening model combined with computer aided virtual screening technique describing high-throughput virtual screening (HTVS). Bayesian classification method and molecular fingerprint similarity were applied to virtual screening technique, for screening compounds in compound library. Some compounds have been found, and then validated further by biological screening model. Combination of HTS and HTVS improves the efficiency of screening SERT inhibitors.

Objective To study the application of P1 adhesin protein epitopes in diagnosis of Mycoplasma pneumoniae(Mp) infected patient. Methods The major epitope(P1-534) of P1 adhesin protein were predicted by ProPred and ANTIGENIC according to its primary structure. The high value fragment was cloned into a constructed recombinant vector. The gene was induced to express fusion protein in E. coli host strain BL21(DE3) and the fusion protein was identified by Western blot. BALB/c mice were immunized with purified protein to test its immunogenicity. Then the purified protein was used as antigen to test the serum of Mp infected patient by ELISA, and compared with the Mp whole cell antigen. Results The P1-534 protein was successfully expressed and purified. ELISA data showed that P1-534 protein could elicit high levels of IgG in immunized mice, the sensitivity and specificity of P1-534 were determined to be 85.00% and 97.67%, while the Mp whole cell antigen were 72.50% and 74.42%. Conclusion The results conformed that the recombinant epitope has certain immunogenicity,and its sensitivity and specificity are better than Mp whole cell antigen. P1-534 protein can be used as an antigen for immunodiagnosis of Mp infection.
