Objective To improve the diagnosis of the lung cancer by fiber bronchoscopy and imaging of chest CT or X-ray.Methods 120 cases of lung cancer were diagnosed by fiber bronchoscopy and pathology,and checked by chest CT or X-ray within a week by fiber bronchoscopy,and then it made a comparison between them.Results 114 cases were the central lung carcinoma,6 cases peripheral lung cancer.The fiber bronchoscopic findings showed that,66 cases were outwardly-oriented growth,35 cases were infiltrative growth,4 cases only showed indirect symptom,8 cases were normal.The pathological finding showed that 79 cases were squamous cell carcinoma,19 cases were adenocarcinoma,16 cases were the small cell lung cancer,6 cases were other type lung cancer.The imaging symptom showed that 78 cases were mass shadow of lung,18 cases only showed obstructive pneumonitis,12 cases only showed obstructive atelectasis,9 cases were vaguely lamellar shadow,3 cases were multiple nodes shadow of bilateral lungs.Conclusion The two examines of fiber-bronchoscopy and imaging have their good quality.The diagnostic level of lung carcinoma is raised by combining with two methods.

Disc polyacrylamide gel clectrophorsis was performed to detect water soluble proteins of the bile－cysts of bear, pig, cow and sheep. The bands of electrophorsis were analysed by means of gel clecrophoresis scan. The results showed that different bile－cysts have different bands.Thus, this method can be used to identify the bile－cyst of bear.

Objective To explore the effectiveness and safety of tiotropium bromide inhalation agent with tulobuterol patch in the treatment of C and D level of COPD in stable period .Methods According to the digital table,255 cases of C and D level in patients with stable COPD were randomly divided into the study group and control group,the patients in study group received inhalation of tiotropium bromide dry powder 18μg/times,one time every day,and give tulobuterol patch(2mg/paste),one time every day.The control group received inhalation of tiotropium bromide dry powder 18μg/times,one time every day.The changes of lung function were observed before and after treatment,the clinical symptom score and inhaled short acting beta 2 agonists used,6min walk test,times of acute exacerbation condition.Results The patients in the two groups after treatment ,pulmonary function ,clinical symptoms score,inhaled short acting beta 2 agonists used,6min walk test,times of acute exacerbation compared with statistical significance(all P<0.05).Subgroup analysis in study group ,emphysema phenotype visible persistent effect ,chronic bronchitis phenotype ,ACOS phenotype early effective treatment ,decreased efficacy after half a year .The adverse reac-tion of two groups of drugs were respectively 19.7%and 21.0%,there was no significant difference in the incidence of adverse reaction between the two groups (χ2 =0.071,P>0.05).Conclusion Tiotropium bromide inhalation agent with tulobuterol patch can improve clinical symptoms and pulmonary function in patients with C and D level part of the stable phase of COPD .
