Analysis of monitoring results of Mattress-type of sleep monitoring system in elderly patients with OSAHS / 临床耳鼻咽喉头颈外科杂志

OBJECTIVE@#To investigate the sleep monitoring feature of the MSMS in elderly patients with OSAHS.@*METHOD@#One hundred and ninety patients diagnosed with OSAHS were divided into elderly group and non elderly group according to age, then the results of MSMS were analyzed.@*RESULT@#Majority elderly patients were with mild to moderate OSAHS. The nocturnal mean blood oxygen and the lowest oxygen were higher than non elderly group, coupled with higher percentage of the total oxygen saturation < 90% monitoring time (TS90). There was no significant difference in sleep structure between two groups, but the total sleep time of elderly group is lower than the non elderly group, the difference is statistically significant.@*CONCLUSION@#The elderly patients with OSAHS were less severe in nature, but the nocturnal hypoxia last longer in the elderly group. There is no significant difference in the sleep structure between the two groups. But the total sleep time decrease in elderly group. With smaller interference, the MSMS is closer to the natural sleep stustus of the subjects.

Nasal mucosa recovery after endoscopic surgery using the plasma radiofrequency ablation at low temperature for treatment of nasal inverted papilloma / 临床耳鼻咽喉头颈外科杂志

OBJECTIVE@#To assess the therapeutic effect and study the role of nasal mucosa epithelization after endoscopic surgery using the plasma radiofrequency ablation at low temperature in patients with nasal inverted papilloma.@*METHOD@#The clinical data of 104 patients with nasal inverted papilloma underwent endoscopic surgery u sing the plasma radiofrequency ablation at low temperature from July, 2008 to July, 2012 were analyzed,and the recovery of mucosa was observed under nasal endoscope.@*RESULT@#The mucosa recovery extent showed a decreasing trend from mucosa pattern degree I to III, where the difference was statistically significant by chi-square test between groups (P < 0.05). The average epithelialization time was 2.7 months. It showed a significantly decreasing trend among average epithelialization time of different degrees of mucosa (P < 0.05). The nasal mucosa of most patients completed epithelialization 2.9 months after surgery.@*CONCLUSION@#It is safe and effective to treat nasal inverted papilloma with plasma radiofrequency ablation at low temperature. The patients should be followed up with regular reexamination for at least three months after surgery.

Reversion of Transforming Growth Factor ?_2 Mediated Immunosuppression in Lung Cancer by Icarrin / 中国肿瘤生物治疗杂志

Objective: To investigate the influence of Icarrin(ICA) on transforming growth factor ?2(TGF?2) expression by PG cells and the mechanisms of reversion of TGF?2 mediated immunosuppression by ICA.Methods: Cell proliferation and cytotoxici- ty were assayed by MTT assay. mRNA level of TGF?2 and perforin was detected by RT-PCR assay. assay.Expression of TGF?2 and IL- 2R? was analysed by folw cytometry assay. Results: ICA could inhibit the protein and mRNA expression of TGF?2 in PG cells. It could also reverse the supressed cytotoxicity of LAK, CD3AK cells by TGF?2. The IL-2R? expression on LAK and perforin gene transcription and proliferation of CD3AK inhibited by TGF?2 were also partly recovered. Conclusion: The anti-anti-tumor activity of ICA is at least partly due to its capability of inhibiting TGF?2 expression in tumor cells and restoring the cytotoxicity of immunocompetent cells inhibited by TGF?2.
