UNLABELLEDBACKGROUND AND OBJECTIVE Telomerase and CYFRA21-1 may be positively expressed in malignant pleural effusion, but the sensitivity and specificity of single tumor marker were low. The aim of this study is to investigate the diagnostic value of combining determination of telomerase activity and CYFRA21-1 levels in differentiating benign from malignant pleural effusion caused by lung cancer.
METHODS80 patients with malignant and 50 patients with benign pleural effusion were enrolled into this study. The telomerase activity in pleural effusion was tested by means of telomeric repeat amplification protocal-PCR-ELISA (TRAP-PCR-ELISA) and CYFRA21-1 levels were tested by the EIA method. All the results were analyzed by the statistical method.
RESULTSThe levels of telomerase and CYFRA21-1 in malignant pleural effusion was significantly higher than that in benign one (t = 17.252 and t = 13.951, P < 0.001). The sensitivity of telomerase activity testing for diagnosing malignant pleural effusion was 71.3%; the specificity was 86.0% and the overall accuracy was 76.9%. The sensitivity of CYFRA 21-1 testing was 60.0%, the specificity was 78.0% and the overall accuracy was 66.9%. The sensitivity of the combined testing was 90.0%, the specificity was 76.0% and the overall accuracy was 86.9%. The sensitivity and the overall accuracy of combined testing were higher than those of telomerase and CYFRA21-1 testing single (chi2 = 9.002 and chi2 = 19.201, P < 0.01; chi2 = 4.389 and chi2 = 14.647, P < 0.05).
CONCLUSIONThe combined testing oftelomerase with CYFRA21-1 can increase the sensitivity and overall accuracy of differential diagnosis of benign and malignant pleural effusion diagnosis.

BACKGROUND AND OBJECTIVEAdenoid cystic carcinoma is primary bronchopulmonary carcinoma with low malignancy, and 43 patients treated in the past 50 years in our hospital were retrospectively studied. The aim of this study is to discuss the clinical symptoms, pathologic characteristic and therapeutic method of primary tracheal or bronchuotracheal adenoid cystic carcinoma.
METHODSThis study summarized total 43 patients of primary tracheal or bronchus adenoid cystic carcinoma treated in our hospital from Jan. 1958 to Dec. 2007. Among them, 40 patients were treated by surgical resection, and 3 patients were treated by fiberoptic bronchoscope's interventional treatment.
RESULTSThe 1-yr, 3-yr, 5-yr survival rates of the 43 patients above were 100% (41/41), 89.5% (34/38), 87.1% (27/31), respectively.
CONCLUSIONPrimary tracheal or bronchus adenoid cystic carcinoma are rare and low malignancy carcinoma. The clinical symptoms of them are not typical. The best treatment is early detection and taking measures of operation plus radiotherapy. The other palliative treatment is fiberoptic bronchoscope's interventional treatment.

BACKGROUND AND OBJECTIVEThe aim of this study is the clinical value of preoperative routine surgical staging to mediastinal lymph nodes on lung cancer.
METHODSSeventy-six cases underwent lymph nodes biopsy with mediastinoscopy. The diagnostic efficacy of thoracic CT scan and mediastinoscopy on mediastinal lymph nodes metastasis were compared.
RESULTSThe sensitivity, specificity, accuracy, positive predictive value and negative predictive value of thoracic CT scan and mediastinoscopy on diagnosing mediastinal lymph nodes metastasis were 68.5%, 66.7%, 68.4%, 84.6%, 16.7% and 87.5%, 100%, 84.2%, 100%, 60%, respectively.
CONCLUSIONRoutine preoperative mediastinoscopy had obvious advantage compared with thoracic CT scan on mediastinal lymph nodes staging. The routine preoperative surgical staging of mediastinal lymph nodes on lung cancer had high clinical value.

BACKGROUND AND OBJECTIVEStudies of passive smoking exposure in China however are of particular interest, because of the high lung cancer rate in people who are mostly non-smokers. The aim of this study is to explore the relationship between passive smoking and lung cancer among non-smoking Chinese.
METHODSBy searching Medline, PubMed, CENTRAL (the Cochrane central register of controlled trials), CBM, CNKI and VIP, et al, we collected both domestic and overseas published documents between 1987 and 2007 on passive smoking and lung cancer among non-smoking Chinese. Random or fixed effect models were applied to conduct meta-analysis on the case control study results, and the combined odds ratio (OR) and the 95% confidence interval (CI) were calculated as well.
RESULTSSixteen documents were included into the combined analysis, which indicated that there was statistical significance between passive smoking and lung cancer (OR = 1.13, 95% CI: 1.05-1.21, P = 0.001). It was significant of lung cancer among non-smoking subjects associated with amount of tobacco passively smoked more than 20 cigarettes daily, with life period in adulthood passive smoking exposure, with gender female, and with exposure to workplace. The P value, OR and 95% CI were P = 0.0003, OR = 1.78, 95% CI: 1.30-2.43; P = 0.0001, OR = 1.50, 95% CI: 1.23-1.83; P = 0.000 7, OR = 1.50, 95% CI: 1.19-1.90; P < 0.0001, OR = 1.41, 95% CI: 1.19-1.66; respectively. And there was no significant difference between passive smoking and lung cancer with amount of tobacco passively smoked within 20 cigarettes daily, with life period in childhood passive smoking exposure, with gender male and with exposure to spouse and parents.
CONCLUSIONPassive smoking is an important risk factor of lung cancer among non-smoking Chinese, and for non-smoking women who expose to environment tobacco smoke in a long period of time have a close relationship with lung cancer risk.

BACKGROUND AND OBJECTIVETransient receptor potential canonical (TRPC) proteins, a group of Ca2' permeable nonselective cation channels, are thought to constitute store-operated calcium channels (SOCC) and mediate store-operated calcium entry (SOCE) in various cell types. Members of TRPC have been found to be involved in abnormal proliferation, differentiation, and growth of cancer cells. The aim of this study is to detect the mRNA and protein expression of TRPC in non-small cell lung cancer (NSCLC).
METHODSReal-time quantitative PCRwas performed to screen the expression of TRPC mRNA in NSCLC tissue. Protein expression of TRPC was detected by Western blot.
RESULTSAmong the seven family members of TRPC so far identified (TRPC1-7), we detected the expression ofTRPC1, TRPC3, TRPC4, TRPC6 mRNA in 24 cases of NSCLC tissue; TRPC2, TRPC5 and TRPC7 mRNA were not detectable. The relative abundance of the expressed TRPC was TRPC1 approximately equal TRPC6 > TRPC3 > TRPC4. Western blot confirmed the protein expression of TRPC1, TRPC3, TRPC4 and TRPC6 in NSCLC tissue.
CONCLUSIONOut of the seven members of TRPC, we found TRPC1, TRPC3, TRPC4, TRPC6 mRNA and protein were selectively expressed in human NSCLC tissue. This study could provide a basis for future exploration of the individual role of these TRPC proteins in mediating SOCE and in the progression of lung cancer.
