Objective To observe the clinical effect of the treatment of bronchial asthma with the Qingfeiyin and Bailing capsule.Methods 107 cases with bronchial asthma were classified into a control group and a treatment group randomly.The control group was treated with the Ipratropine (40-80 ug for each time)and the treatment group was glven Ipratropine and Qingfeireyin(50ml for each time)plus Bailing Capsule(30pills for each time).One course of treatment was 2months.Results The therapeutic effect of treatment group was significantly better than the control group(P＜0.05).Condusion Qingfeiyin and Bailing capsule has excellent effect in treating bronchial asthma.

OBJECTIVE To strengthen the management for visitors in the newborn nursery,in order to reduce the newborn hospital infection rate and enhance the hospital infection management quality in the newborn nursery.METHODS Taken the air and the object surface sampling in the newborn nursery,and the sampling derived from the hands of staff and visitors to undertake the contrast examination.RESULTS Before and after visits,the air pollution rate was over norm by increase of 58.3%,and after disinfection it declined 75.0%,after visiting,the object surface contamination rate was over norm by 56.3%,after disinfection it fell by 77.1%.Before washing-hands,the bacterial contamination rate of visitors and staff was over norm by respectively 100.0% and 68.3%,after washing,the passing rate of visitors was 92.0%,and no medical staff were over norm.CONCLUSIONS To adopt the effective management for visitors in the newborn nursery is very important to reduce the hospital infection rate in newborn nursery.

Objective To identify the role of miR-124 in regulating the radiosensitivity and the epithelial-mesenchymal transition (EMT) of nasopharyngeal carcinoma (NPC). Methods Transient transfection of cells with miR-124 mimic or inhibitor was performed and wound-healing assay was used to investigate the role of miR-124 in the EMT of NPC. The apoptosis affected by miR-124 was also measured after irradiation , followed by investigating the cell proliferation by EdU assay. Finally , proteins of Akt and ERK associated with EMT and radiosensitivity, were measured by western blot. Results The migration index from NPC cell line indicated that miR-124 repressed the EMT. The results from caspase-3 activity assay showed that caspase-3 activity after irradiation significantly increased in miR-124 mimic group compared with the control group (P < 0.01). It was also confirmed that irradiation led to a higher percentage of apoptosis in miR-124 group compared with the control group in NPC cells. Cell proliferation after irradiation was significantly decreased in MiR-124 group as compared with control group . MiR-124 inhibited the protein expression of p-Akt . Conclusion MiR-124 may repress the EMT and decrease radio-resistance of NPC via p-Akt signaling pathway , which may provide a new insight into radio-resistance in NPC.

Objective The radiotherapy resistance is one of important causes for nasopharyngeal carcinoma(NPC) treatment failure.Junctional adhesion molecule A(JAMA)is closely correlated with the tumor poor prognosis.Thus this experiment is to in vestigate the relationship between JAMA expression and the radiosensitivity of NPC.Methods To overexpress or interfere the JAMA expression in CNE2 and HONE1 cell lines.Then different doses of X-ray were adopted to conduct irradiation.The cell clone formation capacity and cellular apoptosis change were detected after 24 h.The role of JAMA in the NPC radiotherapy was understand.The related signal pathway protein in cell lines with different JAMA expression was detected by Western blot.Results The cell lines with low JAMA expression were more sensitive to radiotherapy:After low JAMA expression,the D0 value in the CNE2 cell line was decreased from 3.26 ±0.78 to 1.92 ± 0.23;the Dq value was decreased from 46.51 ± 4.27 to 32.12 ± 3.19.The radio therapy induced apoptosis was significantly increased in the cell lines with low JAMA expression,after low JAMA expressing,thcellular apoptosis was elevated from 6.9 ％ ± 0.9 ％ to 13.7 ％ ± 1.3 ％;the HONE1 cellular apoptosis was elevated from 6.5 ％ + 1.1 ％ to 12.3 ％ ± 1.7％;JAMA overexpression cell lines were significantly decreased.The preliminary mechanism research results showed that JAMA played the effect via Akt signal pathway.Conclusion This research results verifiy that JAMA expression level is closely correlated with the radiosensitivity of NPC cell line:JAMA can increase the radiotherapy resistance of NPC cell lines,which provides a new feasible research direction for NPC enhancing radiosensitivity.
