Objective To explore the diagnostic value of combination detection of carcino‐embryonic antigen(CEA ) ,cytokeratin 19 fragment 21‐1(CYFR21‐1) ,neuron‐specific enolase(NSE) in bronchoalveolar lavage fluid (BALF) for early lung cancer and its correlation with clinical effects .Methods 69 cases of lung cancer were included into the lung cancer group and 50 cases of benign pulmonary disease were included into the lung benign disease group .All the patients were given bronchoalveolar lavage(BAL) .The chemiluminescence immunoassay was adopted to detect the levels of CEA ,CYFR21‐1 and NSE in BALF .The changes of tumor markers levels were compared between the two groups and among different clinical curative effects in the patients with lung cancer . Results The levels of CEA ,CYFR21‐1 and NSE in BALF of the lung cancer group were significantly higher than those of the be‐nign pulmonary disease group ,the difference was statistically significant (P < 0 .05) .The levels of tumor markers in the stage Ⅱ of lung cancer were higher than those in the stage Ⅰ of lung cancer ,the difference was statistically significant (P< 0 .05) ;the levels of CEA ,CYFR21‐1 and NSE in BALF were gradually increased with the decrease of clinical effect (P< 0 .05) ;the sensitivity and spe‐cificity of the combined detection of three tumor markers were 62 .3% and 82 .0% respectively ,which were significantly higher than those of any single tumor marker (P< 0 .05) .Conclusion The levels of CEA ,CYFR21‐1 and NSE in BALF of early lung cancer patients are obviously increased ,moreover which is closely correlated with the pathological stage of lung cancer ,the combined detec‐tion could contribute to improve the detection rate of early lung cancer and guide the evaluation of clinical effect .

Purpose] This paper discusses, in the information era, how to improve col ege English teachers ’ digital literacy. [Method] A questionnaire survey is carried out of the status of col ege English teachers ’ digital literacy in Zhejiang. [Results]Only 25% universities where the respondents work are wel equipped with adequate digital facilities.54% respondents haven ’t received any training in digital technologies and teaching methods. Most of respondents (90%) are interested in digital technologies;however, only 56%of them often use them in class. 90%respondents consider it necessary to receive training in digital teaching technologies. [Conclusion] Firstly, local universities should offer teachers better teaching facilities, more educational resources and training courses; secondly, education of digital literacy and teaching courses should be combined; final y, teachers should possess a correct judgment and improve their awareness of negative information in the virtual environment with self-protection consciousness.

In recent years, the prevalence of allergic rhinitis in children had increased significantly.After a period of time, some children developed into bronchial asthma on the basis of allergic rhinitis, while others did not.To clarify the risk factors of bronchial asthma in children with allergic rhinitis and take early intervention measures are of great significance to the prevention and treatment of bronchial asthma.This article reviews the roles on asthma development of genetics, allergen exposure, types of rhinitis, passive smoking, respiratory infections, early use of antibiotics, and intervention treatment.

Objective To evaluate the relationship between the number of copies of genes and congenital diaphragmatic hernia by the detection of multiple loci in infants with congenital diaphragmatic hernia. Methods Multiple loci were analyzed by Microarray analysis of Affymetrix Cytoscan 750 k in 11 neonates with congenital diaphragmatic hernia, in whom 1 case was twins,and his fraternal twins were diagnosed of fetuse intestinal dilatation. Results A homozygous deletion (8 p11.22 arr[hg19]) was found in one neonate with congenital diaphragmatic hernia, and was eventually confirmed that the depolymerization of the biotin and metalloprotease (ADAM) 3A genes lead to homozygous deletion of the 1～15 exon. Conclusion The alteration of ADAM3A copy number may be the cause of congenital diaphragmatic hernia.

Objective: To explore the effect of cognitive therapy on obsessional compulsive disorder (OCD). Method: Forty-seven patients with OCDO were randomly assigned to cognitive therapy group and conventional treatment group, the later with paroxetine treatment only as control. The results were assessed with Hamilton anxiety scale (HAMA), Yale-Brown Obsessional Compulsive Scale and social disability screening scale. Result: The cognitive therapy group had lower scores in HAMA and Y-BOCS than the control group after 8 weeks therapy, this difference remained in the follow-up after 6 months, when the cognitive group had also lower score in social disability. Conclusion: Cognitive therapy can benefit patients with OCD more than medication only.

Objective To Investigate the factors affecting the post treatment fever in patients with primary liver cancer (PLC) undergone transcatheter arterial chemo embolization(TACE).Methods Seventeen clinical parameters of 102 TACE procedures were determined as independent variables, while the numbers of days running a fever after the procedure of the patients were determined as dependent variables. A multivariate stepwise regression analysis was performed to determine the factors that had affected the duration of fever. Results The factors that affected the fever after TACE were the dose of lipiodol used, ascites, using gelatin sponge(GS), serum albumin level, a history of fever, pre operative leukocyte counts and age. The volume of lipiodol used had played the most important role in affecting febrile time. Conclusions The amount of lipiodol used is the most important factor affecting the post treatment fever in patients with PLC undergone TACE with a tendency of intensification by using GS. The systemic state and the regional state of the liver before the treatments also play some parts in affecting the fever. Some frbrile cases are probably associated with potential infection. The lasting time of fever can be predicted approximately by building up a multivariate regresion equation.

Objective To investigate the application of video-mediastinoscopic biopsy and treatment for pleural effusion. Methods Thirty-two patients with pleural effusion received mediastinoscopic biopsy or treatment. The patients were maintained at a lateral decubitus. A 2 cm incision was made along the midaxillary line for introducing the mediastinoscope. The pleural fluid was drawn out and exploration with biopsy was conducted under mediastinoscope. For 25 patients with malignant hydrothorax, talcum powder was applied for pleurodesis. Results The operation time was 30~70 min (mean, 42 min). A confirmative diagnosis was obtained by video-mediastinoscopy in all the 32 patients, including adencarcinoma in 22 patients, poorly differentiated squamous cell carcinoma in 2, invasive thymoma in 1, tuberculosis in 5, and inflammation in 2. All the operations were successful and the patients recovered smoothly without severe postoperative complications. Conclusions Video-mediastinoscopy is one of effective methods for biopsy and treatment of pleural effusion.

0.05). Conclusion:Administering propofol or midazolam is helpful in avoiding cerebral oxygenation imbalance during CPB.
