[Report of two cases of primary mediastinal tuberculosis].

Two cases of primary mediastinal lymphonode tuberculosis involved right bronchus were summarized in the report. Major clinical symptoms included cough and bloody sputum. Chest enhanced CT scan showed mediastinal lymph node enlargement with ring-shaped enhancement. Bronchoscopy suggested neoplasm in right bronchus. Diagnosis of tuberculosis was confirmed by histopathology in samples from lymph node puncture and brochoscopic biopsy. The clinical symptoms and medical imaging of patients were improved after transbrochoscopic interventional therapy and systemic chemotherapy.

Identification Study of Hydrothorax Telomerase and CEA Test on Benign Pleural Effusion Diagnosis / 浙江中医药大学学报

Objective] To study the determination of telomerase and CEA in differentiating benign and malignant pleural effusions. [Methods] Telomeric repeat amplification ELISA method(TRAP- PCR-ELISA) and enzyme immunoassay(EIA) were measured in 40 patients with malignant pleural effusion and 38 cases of benign pleural effusion telomeres activity and CEA levels. [Results] The telomerase activity in pleural effusions and CEA positive rate in malignant pleural effusion group were 80.0%(32/40) and 85%(34/40), benign pleural effusion group was 7.9%(3/40) and 0%(0/38), malignant pleural effusion of telomerase and CEA-positive rate was significantly higher than benign pleural effusion group, the difference was significant(χ2=40.96,57.26, P0.05). Two combined detection of tumor markers in terms of a positive diagnosis of malignant pleural effusion as the standard, the combined detection sensitivity was 97.5%(39/40), significantly higher than the telomerase and CEA single detection sensitivity 80% and 85%, the differences were statistical y significant(χ2=6.13,3.91,P<0.01). [Conclusion] Detection of the TA and CEA in pleural effusion is of a definite value in differentiating benign from malignant pleural effusion, and the detection of TA is more sensitive and specific than detection of CEA. Combining detection of both markers may raise the accuracy of the diagnosis.

Nursing care of severe asthma patients treated by sedatives and muscle relaxants combined with mechanical ventilation / 中华护理杂志

Objective To introduce the nursing care of severe asthma patients treated by sedatives and muscle relaxants combined with mechanical ventilation. Methods Nurses with more than 3 years of working experiences in respiratory intensive care unit participated in the nursing care,such as ventilation monitoring,sedative effect assessment and artificial airway management. Results All the 18 patients were treated successfully,and the duration of mechanical ventilation ranged from 6 to 192 hours. The indicators of circulation and arterial gas after weaning were improved significantly (P<0.01). Conclusion Proper nursing care and correct sedative effect assessment is an important point to ensure treatment efficacy and reduce complications for severe asthma patients treated by sedatives and muscle relaxants combined with mechanical ventilation.

The application of the transbronchial and percutaneous biopsy guided by computer tomography in pulmonary peripheral lesions / 中国综合临床

Objective To evaluate the comprehensive application of the CT guided transbronchial lung biopsy (CT TBLB) and CT guided percutaneous needle lung biopsy (CT_NLB) in pulmonary peripheral lesions.Methods According to the lesion location in lung field,51 patients were selected to CT TBLB and 46 patients to CT NLB.Results In the comprehensive application of the two lung biopsy methods,the comphensive biopsy success rate was 100%,pathological diagnostic positive rate 87.6% and diagnostic correct rate 97.9% (of them 100% in CT TBLB).The complications of pneumothorax and haemoptysis were decreased significantly.The positive rate and diagnostic correct rate seem higher,but there was no significant difference between the two methods (P
