Objective To explore the therapeutic efficacy of a self-made occluder used for bronchoscopic lung volume reduction(BLVR).Methods Two patients with severe chronic obstructive pulmonary disease(COPD)in stable phase were selected for the present study.One or two nitinol occluders were placed,guided by brochoscopy,into the target bronchi of the two patients.Examination of pulmonary functions,chest computed tomography,complications,blood gas analysis,and evaluation of life quality with St George's respiratory questionnaire(SGRQ)were carried out before and 7 months after the bronchoscopic lung volume reduction.Results No dislodging or shifting of all the inserted occluders occurred.Only slight proliferation of granulation tissue was found in mucous membrane around the occluder,and atelectasis was observed at the target sites of lung.Before and 7 months after BLVR,ventilatory capacity(VC)of case 1 rose from 3.08L to 3.57L,and that of case 2 was elevated from 2.19L to 2.58L.Forced vital capacity(FVC)of case 1 was elevated from 2.87L to 3.57L,and that of case 2 from 2.60L to 2.58L.SGRQ showed a remarkable improvement of patients' dyspnea with a decrease of scores from 62 to 26 in case 1 and from 48 to 23 in case 2.No evident changes were found on arterial oxygen blood partial pressure(PaO2)in both patients,and no severe complications such as obstructive pneumonia or pneumothorax occurred yet in either case 1 or case 2.Conclusion The present study has demonstrated that the self-made occluder is convenient for insertion with satisfactory stability and therapeutic efficacy.Application of such occluder is safe with few complications,and may serve the purpose of reducing lung volume and improving lung function.

Objective To construct pcDNA 3.1(+)/HPV 18 E 6 fusion gene and a single-codon mutation pcDNA 3.1(+)/E6 F49R or pcDNA 3.1(+)/E6 F127R fusion gene in eukaryotic expression vector and study the effects on proliferation and apoptosis of cervical carcinoma cell line Hela. Method HPV 18 E6 gene sequence and the single-point mutation HPV 18 E6 F49R or HPV 18 E6 F127R were amplified from total RNA of Hela cell line by reverse transcription- polymerase chain reaction ( RT- PCR), then the gene sequences were respectively inserted into pcDNA 3.1(+) vector to reconstruct recombinant plasmids which were transfected transiently into Hela cells. MTT and RT-PCR were used to test the expression levels of HPV 18 E6 and the growth of HeLa cells after transfected about 48 h. The proliferation and apoptosis of Hela cells were detected respectively by cell counting and AO/EB fluorescent vital staining. Results The pcDNA 3.1(+)/HPV 18 E6, pcDNA 3.1(+)/E6 F49R and pcDNA 3.1(+)/E6 F127R eukaryotic expression vectors were successfully constructed. The gene of HPV 18 E6 was discriminably detected in the HeLa cells which were transfected with the recombinant plasmids. After several days, the proliferation of Hela cells transfected with pcDNA 3.1(+)/E6 F49R or pcDNA 3.1(+)/E6 F127R plasmid were obviously inhibited and the apoptotic rates were significantly increased, then the proliferation of cells transfected with pcDNA(+)/HPV 18 E6 was rather increased slightly, and we could observe the phenomena of early apoptosis and the formation of thekaryopyknosis by fluorescent microscope in the cells transfected with pcDNA 3.1(+)/E6 F49R or pcDNA 3.1(+)/E6 F127R. Conclusion The eukaryotic expressing vectors encoding HPV 18 E6 F49R and HPV 18 E6 F127R provide fundamental basis for the further study on HPV 18 E6 mechanism as well as prevention and treatment of uterine cancer.
