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.

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.

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.

Gui-Ling-Ji (GLJ), a classical prescription of traditional Chinese medicine (TCM), is the only existing compound of refining agent after 400-year testing. It is also one of 4 kinds of TCM secret varieties of the first batch after liberation. However, due to the lack of in-depth modern research, the magical effect of GLJ has not been fully understood and the clinical application has also been influenced. This article analyzed the situation and problems of secret varieties and GLJ. Experiences and strategies of the successful redevelopment of secret varieties were re-ferred to. Then, this paper proposed modern research thoughts of GLJ in order to realize the actively protection and the second development of the prescription.

Objective To investigate the prevalence of plasmid-mediated quinolone resistance (PMQR) genes among clinical isolates of Klebsiella pneumoniae (K.pneumoniae) in pediatrics.MethodsA total of 131 non-duplicate clinical isolates of K.pneumoniae were collected in the Affiliated Children′s Hospital of Capital Institute of Pediatrics from 2010 to 2012.PMQR genes [qnrA, qnrB, qnrS, aac(6′)-Ⅰb-cr and qepA], mutations in the quinolone resistance-determining region (QRDR) and extended spectrum β-lactamases (ESBLs) genes in those strains were analyzed by PCR.Minimum inhibitory concentrations (MIC) of different antibiotics against those K.pneumoniae strains were determined by broth microdilution method and E-test according to the guidelines issued by the Clinical and Laboratory Standards Institute (CLSI).Transferability of the PMQR genes was examined by conjugation test with the sodiumazide-resistant Escherichia coli J53.Results Among the 131 isolates, 9.92% were resistant to quinolone and 30.5% were positive for PMQR genes, including 6.87% harboring qnrB gene, 22.9% harboring qnrS gene and 4.58% harboring aac(6′)-Ⅰb-cr gene.Neither qnrA-positive nor qepA-positive strain was detected.Among these PMQR genes-positive isolates, 90% were ESBLs-producing strains and two presented mutations in gyrA and parC genes.Conjugation test showed that these PMQR genes could be transferred horizontally and the ciprofloxacin resistance increased 2 to 32 folds in transconjugants.Conclusion This study indicates that the PMQR gene-carrying rate is high in K.pneumoniae strains isolated in paediatrics in China.Most of the PMQR gene-positive strains are also ESBLs-producing strains.The PMQR genes could be transferred horizontally in bacteria.

Objective To inspect the source of an outbreak with Mycoplasma pneumoniae (Mp).Methods We carried out real-time PCR to analyze specimens collected from pediatric patients in Beijing during January 2010 to May 2012,diagnosed as pneumonia or a respiratory infection according to clinical symptoms.These positive samples were analyzed by the M-P typing system(M:multiple-locus variable-number tandem-repeat analysis,MLVA; P:P1-restriction fragment length polymorphism analysis,P1-RFLP).Results Sixty-nine specimens were tested positive to Mp by the real-time PCR in 446 specimens from pediatric patients.The infection rate was 11.69％,15.56％ and 20.00％ respectively in 2010,2011 and the first half of 2012.According to the M-P system,11 distinct genotypes were identified from 69 positive specimens,M43562P1 and M53562P1 were the two main genotypes that showed an increasing trend from 2010 to 2011,and M33562P1 and M63562P1 showed an increasing trend from 2011 to 2012 in China.Conclusion During this international Mp epidemic,the infection rate of Mp was also increase in Beijing in 2011,and M43562P1 and M53562P1 were the two main genotypes.Among them,M43562 were consistent with pop genotypes in Europe,and M53562 were consistent with pop genotype in Israel.The M-P system would be valuable to monitor the epidemic of Mp in different countries in the world.

This study is to investigate the effect of the effective components group of Xiaoshuantongluo (XECG) on neuronal injury induced by oxygen-glucose deprivation (OGD) in primary cortical cultures isolated from SD rat cortex at day 3 and the possible mechanism. Cells were divided into control group, OGD model group and XECG group (1, 3 and 10 mg x L(-1)). The cell viability was assessed with MTT assay and the LDH release rate was measured by enzyme label kit. The cell apoptosis was analyzed using Hoechst staining. RT-PCR was applied to detect the mRNA levels of JAK2 and STAT3. Western blotting was used to detect the expressions of Bcl-2, Bax, p-JAK2 and p-STAT3 proteins. Results showed that XECG resulted in an obvious resistance to oxygen-glucose deprivation-induced cell apoptosis and decrement of cell viability, decrease the cell LDH release rate. XECG could adjust the expression of Bcl-2 and Bax proteins and increase Bcl-2/Bax ratio, up-regulate the expression of p-JAK2 and p-STAT3. In conclusion, XECG could protect against the neuronal injury cells exposed to OGD, which may be relevant to the promotion of JAK2/STAT3 signaling pathway, and impact the expression of Bax and Bcl-2.
