RESUMEN
Chest trauma is one of the most common injuries. Venous thromboembolism (VTE) as a common complication of chest trauma seriously affects the quality of patients′ life and even leads to death. Although there are some consensus and guidelines on the prevention and treatment of VTE at home and abroad, the current literatures lack specificity considering the diagnosis, treatment and prevention of VTE in patients with chest trauma have their own characteristics, especially for those with blunt trauma. Accordingly, China Chest Injury Research Society and editorial board of Chinese Journal of Traumatology organized relevant domestic experts to jointly formulate the Chinese expert consensus on the diagnosis, treatment and prevention of chest trauma venous thromboembolism associated with chest trauma (2022 version). This consensus provides expert recommendations of different levels as academic guidance in terms of the characteristics, clinical manifestations, risk assessment, diagnosis, treatment, and prevention of chest trauma-related VTE, so as to offer a reference for clinical application.

@#Objective To explore the factors that affect the accuracy of percutaneous thermal ablation of lung metastases and coping strategies. Methods We retrospectively analyzed the clinical data of 31 patients who met the conditions for thermal ablation of lung metastases in Ninth People’s Hospital affiliated to Shanghai Jiao Tong University School of Medicine between October 2019 and December 2020. There were 19 males and 12 females with a mean age of 40-81 (62.8±10.3) years. A total of 33 metastases tumors were thermally ablated, 12 were radiofrequency ablation and 19 were microwave ablation. Results Of the 33 metastatic tumors, 5 targets showed significant puncture deviation, 4 of them completed the ablation after adjustment and 1 failed. The result of the univariate logistic regression showed the distance within the lung parenchyma (P=0.043) and the maximum diameter of the tumor (P=0.025) were independent risk factors for the accuracy of percutaneous thermal ablation. In terms of correlation, there was a positive correlation between the accuracy of percutaneous thermal ablation and the distance within the lung parenchyma (P=0.033), and a negative correlation between the maximum diameter of metastases tumor (P=0.004) and hemoptysis (P=0.015). Complete ablation rate was 87.8% (29/33). Conclusion When we perform CT-guided percutaneous thermal ablation of lung metastases, we must fully prepare the deviation plan for the small diameter tumor, the long travel distance in the lung parenchyma, and hemoptysis during puncture. Complete ablation can be achieved by fully identifying the anatomical features of the tumor and its surrounding structures, shortening the travel distance in the lung parenchyma and increasing the ablation range.

@#Objective To explore the surgical design and efficacy of novel modified Nuss procedure for pectus excavatum (PE). Methods We retrospectively analyzed the clinical data of 903 patients with PE who were treated by the new kind of steel bar and the novel modified Nuss procedure. There were 716 males and 187 females at mean age of 2-45 (12.1±6.8) years. Preoperative chest CT scans Haller index (HI) was 3.1-15.2 (4.6±1.3), with 38 patients of mild PE (HI<3.2), 302 patients of moderate PE (HI 3.2-3.5), 521 patients of severe PE (HI 3.6-6.0), and 42 patients of extremely severe PE (HI>6.0). The operative time, operative blood loss, hospital stay time as well as postoperative complications were reviewed and analyzed. Results All of the 903 patients successfully completed the surgery. The mean operative time was 20-45 (25.2±2.6) min for primary PE and that for special type of PE (including recurring PE, PE patients after heart disease operation and those corrected by 2 bars) was 48-150 (63.5±28.1) min. Blood loss was less than 10 mL for primary PE and 15-50 (23.5±5.5) mL for special type of PE. Postoperative hospital stay was 3-15 (4.5±1.6) d. A total of 845 patients (93.6%) required 1 steel bar insertion, 58 patients (6.4%) required 2 steel bars. Postoperative evaluation of the surgery outcomes revealed the following: excellent in 805 patients, good in 84 patients, fair in 14 patients and poor in 0. The good quality rate was 98.4%. Conclusion Novel modified Nuss procedure can simplify and optimize the surgical design with good short and mid-term effects.

@#Objective To share the experience of single-stage bilateral pulmonary resections by video-assisted thoracic surgery (VATS) for multiple nodules. Methods Clinical records of patients undergoing one-stage bilateral resections of multiple pulmonary nodules between January 2015 and December 2016 in our institution were retrospectively reviewed and analyzed. There were 9 males and 15 females, aged from 33 to 69 (55.0±8.0) years. Two patients underwent bilateral lobectomy. Lobar-sublobar (L/SL) resection and bilateral sublobar resection (SL-SL) were conducted in 9 patients and 13 patients respectively. Results All operations completed successfully. Operation time was 135–330 (231.4±59.1) min, duration of use of chest drains was 2–17 (5.4±3.1) days. Overall duration of hospitalization after surgery was 5–37 (8.6±6.3) days. There was no perioperative death. Postoperative course was uneventful in 17 (70.8%) patients. The postoperative complications included one patient of incision infection and one patient of pulmonary infection. Persistent air leak for >3 days duration and unilateral pleural drainage for more than 200 ml/d were observed in 3 patients and 2 patients respectively. Conclusion Single-stage bilateral surgery in selected patients with synchronous bilateral multiple nodules is feasible and associated with satisfactory outcomes.
RESUMEN
BACKGROUND:A large number of experiments have shown that bone marrow mesenchymal stem cels (BMSCs) have good effects on the treatment of lung disease or improvement of lung injury, and its therapeutic effect is mainly oriented to reduce the inflammatory response. OBJECTIVE: To study the effects of BMSCs combined with reduced glutathione in murine models of bleomycin-induced lung injury. METHODS:BMSCs were isolated from a male NOD/SCID mouse and cel morphology and phenotype were observed. Sixty-four female NOD/SCID mice were randomly divided into a control group, a model group, a BMSCs group and a BMSCs+reduced glutathione group (combined group). The control group received intratracheal injection of normal saline, the model group received intratracheal injection of bleomycin, and the BMSC group received BMSCs injectionvia the tail vein at 2 hours after intratracheal injection of bleomycin, and combined group received BMSCs+reduced glutathione injection via the tail vein at 2 hours after intratracheal injection of bleomycin. Al mice were kiled after 7 days, and levels of tumor necrosis factor-α, interleukin-β, malondialdehyde in lung tissue were detected and lung tissue specimens were obtained for pathological examination. RESULTS AND CONCLUSION:BMSCs were fibroblast-like cels, Positive for CD10, CD13 and CD44, but negative for CD34 and CD45. Compared with the control group, the levels of tumor necrosis factor-α, interleukin-β and malondialdehyde were increased in the model group, while decreased significantly in the BMSCs group and combined group (P < 0.05), especialy in the combined group (P < 0.05). Pathological examination showed that more serious lung injury was observed in the model group and BMSCs group than the combined group. These findings indicate that BMSCs combined with reduced glutathione can more effectively protect against bleomycin-induced lung injury.
