Clinical Prediction of Lung Cancer Complicated with Pulmonary Infection After Thoracoscopic Surgery Based on Nomogram Model / 肿瘤防治研究

Objective To analyze the risk factors of lung cancer patients complicated with pulmonary infection after thoracoscopic surgery and establish a predictive nomogram model. Methods A total of 315 patients with primary lung cancer who had undergone thoracoscopic surgery from January 2018 to October 2021 in our hospital were divided into two groups according to the incidence of pulmonary infection. Two groups of clinical data were collected for single-factor and regression analyses, and independent predictors were obtained. On this basis, a risk model was constructed and its predictive effectiveness was evaluated. Results The independent risk factors of lung cancer patients complicated with pulmonary infection after thoracoscopic radical operation were as follows: age≥62.5 years, smoking index≥100, PEF≤72.1 ml/s, TNM stage Ⅲ/Ⅳ, and operation time≥188.5 min (P < 0.05). Based on the above factors, the risk model of the column chart was established. Model-verification results showed that the C-index of the model was 0.909, and the correction curve showed that the column chart model had good differentiation and consistency. Conclusion Lung cancer patients' age, smoking index, TNM stage, PEF, and operation time are closely related to pulmonary infection after thoracoscopic radical operation. The nomogram model is useful for identifying high-risk patients and reducing postoperative complications.

Research progress in the characteristics and differential diagnosis of tuberculous pleural effusion and malignant pleural effusion / 国际生物医学工程杂志

Pleural effusion is a common clinical pleural disease, and it is also an accompanying manifestation of many diseases. The characteristics and etiological diagnosis of pleural effusion have always been the focus of clinical attention. Pleural effusion is divided into exudate and exudative effusion, and tuberculous pleural effusion and malignant pleural effusion are more common in exudative pleural effusion. Its characteristics and the selection of appropriate diagnostic methods are crucial to the treatment and prognosis of patients. With the rapid development of experimental technology and molecular biology, some new experimental techniques and experimental indicators have emerged. In this review, the characteristics of tuberculous pleural effusion and malignant pleural effusion and the research progress of its differential diagnosis methods were reviewed.

Fixed operation of multiple rib fraotures in chest trauma / 中华胸心血管外科杂志

Objective Summarize and analyze surgical treatment experience and clinical application value for severe chest trauma with multiple rib fractures (which has a positive rate of occurrence),the treatment method is to surgically fix titanium plate to ribs at the early stage of the fractures.Methods Adopted 161 severe chest trauma cases require thoracotomy from June,2007 to June,2012.The patients were arranged as two groups according to the doctor's requirements by our fulltiem horses.79 cases of normal thoracotomy operations were recorded as control group ; at the same period 82 cases thoracotomy operation with ribs internally fixed treatment were recorded as the group of internal plate fixing treatment group.Then compare the results of postoperative paradoxical respiration,oxygen concentration,lung function,chest drainage,length of stay and others after operations.Results The treatment results include oxygen saturation of blood,lung function,and length of stay,the complication rate and death rate.The results of ribs intemafly fixed group are better than the control group on average.Conclusion Apply internal plate fixing operation to ribs during the thoracotomy will effectively control thoracic paradoxical respiration and prevent respiratory failure,improve lung function,reduce death rate of chest trauma and the complication and be helpful for rapid recovery.
