BACKGROUNDTo investigate the expression of COX-2 and its relation to clinical pathophysiological features and prognosis in non-small cell lung cancer (NSCLC).

METHODSThe expression of COX-2 protein was detected in 52 NSCLC tissues by immunohistochemical (S-P) method.

RESULTSThe positive COX-2 expression was observed in 25 (48.1%) cases of NSCLC tissues. The positive rate of COX-2 expression was 76.5% and 34.3% in adenocarcinoma and squamous cell carcinoma respectively (P < 0.01). The positive rate of COX-2 expression in T3+T4 disease (92.3%) was remarkably higher than that in stage T1+T2 (33.3%) (P < 0.01). There was a remarkable difference in COX-2 expression rate between clinical stage I+II (28.1%) and clinical stage III+IV (80.0%) groups (P < 0.01). The positive rate of COX-2 expression was 83.3% in those with lymph node metastasis, but only 17.9% in those without lymph node metastasis (P < 0.01). In addition, there were significant differences in positive rate of COX-2 expression among patients with ≤2, > 2 but < 5, ≥5 years of survival span respectively (P < 0.01).

CONCLUSIONSOverexpression of COX-2 in NSCLC, especially in adenocarcinoma, is closely related to invasion, lymph node metastasis and clinical stage of lung cancer. It may play a role in development of NSCLC, and also may be a prognostic marker.

OBJECTIVE To investigate the contribution of the GJB6 gene [encoding connexin 30 (C?30)] mutations in Chinese population with sporadic non-syndromic hearing impairment. METHODS PCR reactions were performed with two pair of primers for the coding sequence of GJB6 gene and for the deletion of GJB6. PCR products bidirectional sequencing was subsequently applied in 214 patients with hearing loss and 86 normal controls. RESULTS A novel heterozygous mutation-233(C→A) was found, which results in amino acid change, A78D. This mutation wasn't detected in the control subjects. The altered valine residue lies within the second conserved transmembrane domain. The large deletion△(GJB6/ D13S1830)] of GJB6 was not found in this group. CONCLUSION The large deletion of GJB6 was not found in the Chinese deafness population. A novel heterozygous mutation of GJB6 was found. These results indicated GJB6 mutations are not a major cause of hearing loss in the Chinese population.

Objective To compare the development of gastric insufflation related to different peak inspiratory pressures (PIPs) during facemask ventilation in the pediatric patients.Methods Ninety male pediatric patients,aged 2-4 yr,of American Society of Anesthesiologists physical status Ⅰ,scheduled for elective surgery under general anesthesia,were randomly divided into 5 groups (n =18 each) using a random number table:PIP 8 cmH2O group (group P8),PIP 10 cmH2O group (group P10),PIP 12 cm H2O group (groupP12),PIP 14cmH2O group (group P14) and PIP 16 cmH2O group (group P16).Anesthesia was induced with fentanil,propofol and rocuronium in sequence.After loss of eyelash reflex,positive pressure facemask ventilation was performed for a 120 s period in pressure-controlled mode.Gastric insufflation was detected by real-time ultrasonography of the antrum,and cross-sectional antral area was measured using ultrasonography before facemask ventilation and at 120 s of facemask ventilation.The pulse oximetry (SpO2),tidal volume (VT),end-tidal pressure of carbon dioxide (PETCO2) and end-tidal oxygen concentration (ETO2) were recorded at 30,60,90,and 120 s of facemask ventilation.The development of gastric insufflation and hypoventilation was recorded.Results Compared with group P8,the incidence of gastric insufflation was significantly increased in group P16 (P＜0.01),and no significant change was found in the incidence of gastric insufflation in the other groups (P＞0.05),the incidence of hypoventilation was significantly decreased,VT and ETO2 were increased,and PET CO2 was decreased in P12,P14 and P16 groups,and PETCO2 was significantly decreased at 120 s of facemask ventilation (P＜ 0.05 or 0.01),and no significant change was found in the other parameters in group P10 (P＞0.05).Compared with P12 and P14 groups,VT was significantly increased,PEHTCO2 was decreased at 120 s of facemask ventilation (P＜0.05),and no significant change was found in the incidence of hypoventilation and ETO2 in group P16 (P＞0.05).There was no significant difference between group P12 and group P14 in the incidence of hypoventilation,VT,PETCO2 and ETO2 (P＞0.05).The pediatric patients showed a certain CO2 accumulation [PETCO2 (40.6±4.0) mmHg] at 120 s of facemask ventilation in group P8,and the pediatric patients showed excessive ventilation [PETCO2 (23.6± 1.4) mmHg],and cross-sectional antral area was not measured using ultrasonography in three cases because of excessive gastric insufflation in group P16.Conclusion PIP at 12-14 mmHg in pressure-controlled ventilation mode can not only ensure adequate preoxygenation and but also avoid excessive gastric insufflation during facemask ventilation in the pediatric patients.
