Traumatic hemothorax is a common disease in chest trauma .If it is not treated properly and effectively , it will lead to continuous blood loss, clotted hemothorax, empyema and other life-threatening conditions.Because of no universally ac-cepted guide or consensus in the treatment of traumatic hemothorax , clinicians often choose different ways to treat different de-grees and types of traumatic hemothorax according to their habits and experience .This article focus on recent studies on the treatment of traumatic hemothorax , summarize the latest achievements in the field of traumatic hemothorax , provide evidence for clinicians'clinical decision-making, and find the current insufficiency of traumatic hemothorax and the direction for further re-search.

Objective:Anterior cruciate ligament injury is the most common type of knee joint ligament injury.Anterior cruciate ligament reconstruction has a high failure rate,with bone tunnel abnormalities as the most significant factor in these failures.Digital orthopedic technology can effectively develop implementation plans for the revision,thus increasing the success rate.This study aims to develop a surgical plan for anterior cruciate ligament revision by employing multiplanar reconstruction(MPR)for measuring bone tunnel position and diameter,and simulating bone tunnel creation via 3D printing preoperatively. Methods:A total of 12 patients who underwent anterior cruciate ligament revision at the Third Xiangya Hospital of Central South University between 2014 and 2021 were retrospectively studied.The data included patient demographics,preoperative formulated knee joint 3D printing models,and preoperative knee CT scans.The study measured the bone tunnel's diameter and position to guide the establishment of revision bone tunnels during surgery,reassessed the postoperative bone tunnels,and evaluated knee joint functional scores[including International Knee Documentation Committee Knee Evaluation Form(IKDC)score,Lysholm score,and Tegner exercise level score]. Results:Preoperative measurements revealed suboptimal femoral tunnels positions in 4 patients and tibial tunnels positions in 2 patients.MPR and 3D printing technology were used to guide the establishment of a new bone canal during surgery,and postoperative measurements were satisfactory for all patients.Preoperative measurements demonstrated the interclass correlation coefficient for femoral tunnels and tibial tunnels diameters were 0.843(P<0.05)and 0.889(P<0.001),respectively.Meanwhile,the intraclass correlation coefficient were 0.811(P<0.05)and 0.784(P<0.05),respectively.The intraoperative diameter of femoral and tibial tunnels showed excellent correlation with postoperative CT measurements,with intraclass correlation coefficient values of 0.995(P<0.001)and 0.987(P<0.001),respectively.All bone tunnel positions were within the normal range.At the final follow-up,knee joint function scores in all 12 patients improved significantly compared to pre-surgery(P<0.001),and the reoperation rate was zero. Conclusion:MPR and 3D printing technology can accurately measure the parameters of reconstructed anterior cruciate ligament bone tunnels.Personalized revision plans for patients with reconstruction failure enhances the success rate of revision surgery and improves patient prognosis.

BACKGROUND: It has been known that the volume doubling time (VDT) of different lung nodule types is different. At present, there is still a lack of studies about the volume doubling time of lung cancer with different pathological types. The purpose of the study is to explore the factors influencing the progression of the early-stage adenocarcinoma, and provide some reference for the follow-up strategy of lung nodules by retrospective analysis of the image data of 143 early-stage adenocarcinoma. METHODS: 143 cases of the early adenocarcinoma were classified according to the 2015 World Health Organization Classification of Lung Tumors and the Eighth edition of the tumor-node-metastasis (TNM) classification of lung cancer. The volume doubling time was calculated with reference to the revised Schwartz formula. RESULTS: Among the 143 cases of the early adenocarcinoma, 50 cases (34.97%) were in progression. By multivarIate analysis, there were several factors associated with the progression of the early adenocarcinoma: the follow-up time, the dimension of nodule, the pathological type, the nodule type and the pathological stage. The VDT of lepidic predominant adenocarcinoma (LPA) is (594±272) d. The VDT of the invasive adenocarcinoma with lepidic part, but not predominant, is (520±285) d. The VDT of the invasive adenocarcinoma without lepidic part is (371±183) d. CONCLUSIONS About 35% of the early adenocarcinoma is in progress. Whether with the lepidic component is a positive factor to the speed of tumor progression.

【Objective】 To investigate the safety and effectiveness of suctioning flexible ureteroscopy with intelligent pressure-control at different times after drainage for patients with urogenic sepsis complicated with upper urinary tract stones. 【Methods】 Clinical data of 59 patients treated in the Department of Urology, Affiliated Hospital of Nantong University during May 2022 and May 2023 were collected.The patients were divided into early lithotripsy (≤1 week) group (n=27) and late lithotripsy (>1 week) group (n=32).Baseline data, imaging data and postoperative data of the two groups were compared. 【Results】 There were no significant differences between the two groups in the stone-free rate, total incidence of complications, incidence of high-grade complications, length of stay after lithotripsy, hospitalization costs after lithotripsy and total hospitalization costs (P>0.05). 【Conclusion】 Both early lithotripsy (<1 week) and late lithotripsy (>1 week) are safe and effective in the treatment of urogenic sepsis after drainage.

Objective    To establish the gene-based esophageal cancer (ESCA) risk score prediction models via whole transcriptome analysis to provide ideas and basis for improving ESCA treatment strategies and patient prognosis. Methods    RNA sequencing data of esophageal squamous cell carcinoma (ESCC), esophageal adenocarcinoma (EAC) and adjacent tissues were obtained from The Cancer Genome Atlas database. The edgeR method was used to screen out the differential genes between ESCA tissue and normal tissue, and the key genes affecting the survival status of ESCC and EAC patients were initially identified through univariate Cox regression analysis. The least absolute shrinkage and selection operator regression analysis and multivariate Cox regression analysis were used to further screen genes and establish ESCC and EAC risk score prediction models. Results    The risk score prediction models were the independent prognostic factors for ESCA, and the risk score was significantly related to the survival status of patients. In ESCC, the risk score was related to T stage. In EAC, the risk score was related to lymph node metastasis, distant metastasis and clinical stage. The constructed nomogram based on risk score showed good predictive ability. In ESCC, the risk score was related to tumor immune cell infiltration and the expression of immune checkpoint genes. However, this feature was not obvious in EAC. Conclusion 聽 聽The ESCC and EAC risk score prediction models have shown good predictive capabilities, which provide certain inspiration and basis for optimizing the management of ESCA and improving the prognosis of patients.
