Objective To investigate the value of video-assisted thoracoscopic surgery(VATS)in the treatment of coagulated hemothorax.Methods A prospective randomized controlled study.Between July 2005 and July 2007,62 patients with coagulated hemothorax were enrolled in this study.The patients were randomly divided into VATS and traditional thoracotomy groups(31 in each).The pathophysiological parameters of the two grups were compared.Results No significant difference in the sex,age,property and location of the wound,and rate of complicated injuries was noticed between the two groups.The mean operation time,duration of postoperative drainage,and postoperative hospital stay of the VATS group were significantly shorter than those in the traditional group [(52.1?24.4)min vs(120.2?47.2)min,t=-7.136,P=0.000;(1.7?0.7)d vs(4.8?1.8)d,t=-8.937,P=0.000;and(12.6?2.4)d vs(18.0?8.9)d,t=-3.262,P=0.002;respectively];and the mean intraoperative blood loss and the volume of thoracic drainage of the VATS group were significantly lower than those in the traditional group [(137.1?14.6)ml vs(203.2?53.4)ml,t=-6.648,P=0.000;and(181.3?37.9)ml vs(253.9?64.0)ml,t=-5.435,P=0.000,respectively].No significant difference in the rate of complications existed between the two groups(0 vs 1 case,?2=0.000,P=0.000).Conclusion Video-assisted thoracoscopy is feasible and safe for coagulated hemothorax and is worth being widely used.

Objective To investigate the effect of video-assisted thoracoscopic surgery( VATS) in thoracic disease,and the feasibility to carry out VATS for basic hospital. Methods The data of VATS treatment were collected to compare the differences between study group and control group,and evaluate the the feasibility to carry out VATS for basic hospital. Results The operation time was (100. 75±22. 72) min, blood loss was (54. 27±26. 21) mL,postoperative drainage was (920. 67±171. 99) mL. The postoperative complications were fewer,post-operative hospital stay was shorter,incision time was shorter(P=0. 000) and pain scores was lower(P=0. 000) in study group than that in control group. Basic hospital has the capacity to conduct this technical. Conclusion VATS is feasible to carry out in basic hospital.

Temporomandibular joint (TMJ) diseases are common clinical conditions. The number of patients with TMJ diseases is large, and the etiology, epidemiology, disease spectrum, and treatment of the disease remain controversial and unknown. To understand and master the current situation of the occurrence, development and prevention of TMJ diseases, as well as to identify the patterns in etiology, incidence, drug sensitivity, and prognosis is crucial for alleviating patients′suffering.This will facilitate in-depth medical research, effective disease prevention measures, and the formulation of corresponding health policies. Cohort construction and research has an irreplaceable role in precise disease prevention and significant improvement in diagnosis and treatment levels. Large-scale cohort studies are needed to explore the relationship between potential risk factors and outcomes of TMJ diseases, and to observe disease prognoses through long-term follw-ups. The consensus aims to establish a standard conceptual frame work for a cohort study on patients with TMJ disease while providing ideas for cohort data standards to this condition. TMJ disease cohort data consists of both common data standards applicable to all specific disease cohorts as well as disease-specific data standards. Common data were available for each specific disease cohort. By integrating different cohort research resources, standard problems or study variables can be unified. Long-term follow-up can be performed using consistent definitions and criteria across different projects for better core data collection. It is hoped that this consensus will be facilitate the development cohort studies of TMJ diseases.
