Objective: To evaluate the accuracy and clinical value of fractional lfow reserve (FFR) determined by CT coronary angiography (CTA) in relevant patients. Methods: A total of 43 patients treated in our hospitals from 2013-10 to 2015-10 were retrospectively studied. There were 29 (67.40%) with male gender, the average age was (60.2±10.1) years. The patients received CTA at 1 week prior coronary angiography (CAG), the interval between CTA and CAG was (5.4±1.6) days. FFR was measured by both CAG and CTA (FFRCT) in selected target vessel which was deifned as maximal diameter reduction 50% to 70%. The imaging data were recorded and compared, FFRCT was calculated. Results: 48 vessels from 43 patients were eligible for analysis as target vessels. FFRCT vas evaluated based on the gold criteria of FFR. FFRCT had the diagnostic accuracy at 83.3%, sensitivity 75.0%, speciifcity 89.3% and positive predictive value was 83.3%, negative predictive value was 83.3% respectively. FFR and FFRCT showed obvious correlation (r=0.704,P<0.001); Bland-Altman analysis presented good concordance with 95% limits of agreement for FFRCTand FFR value ranged from -0.12 to 0.16, and 95.8% of the points (46/48) fell in the 95% limit of agreement, Receiver operating characteristic curve indicated that AUC of FFRCT was 0.871 (95% CI 0.770-0.973). Conclusion: CTA could accurately assess FFR, and FFRCT might be used in guiding the treatment for patients with intermediate coronary stenosis in clinical practice.

Objective To investigate the MR findings of fetal cleft lip (CL) and evaluate the advantages and limitations of MRI in the diagnosis. Methods Twelve pregnant women suspicious of fetal CL/cleft palate(CP) on ultrasonography were enrolled in the study. The findings of ultrasonography, MRI and following-up were compared. Results MRI and ultrasonography detected 12 fetuses with CL/CP. The following-up results showed 1 case with incomplete cleft lip and the other 11 cases with complete cleft lips and cleft palates. MRI and unltrasonography were consistent with the follow-up in CL detection, showing completed or uncompleted soft tissue interruption of the fetal lips with amniotic fluid filling which is high signal on T_2WI. On MRI, CP showed discontinuous of the soft tissue which were interrupted by long T_2 signal and communicating with oral cavity and nasal cavity. MRI missed 1 case and excluded 1 case of CP. Ultrasonography predicted 5 case of CL, excluded 1 CP but missed 6 cases. The accuracy, sensitivity and specificity in detection CL/CP was 91.7% (11/12), 90.9% (10/11), 100% (1/1) for MRI and 50.0% (6/12),45.5% (5/11), 100% (1/1) for ultrasonography, respectively. Conclusion MR imaging had advantage over ultrasonography in detecting CP, MRI is an essential when CP is suspicious on ultrasonography.

Traumatic rib fractures are the most common injury in thoracic trauma. Previously,the patients with traumatic rib fractures were mostly treated non-surgically,of which 50%,especially those combined with flail chest presented chronic pain or chest wall deformities and over 30% had long-term disabilities,being unable to retain a full-time job. In the past two decades,thanks to the development of internal fixation material technology,the surgical treatment of rib fractures has achieved good outcomes. However,there are still some problems in clinical treatment,including inconsistency in surgical treatment and quality control in medical services. The current consensuses on the management of regional traumatic rib fractures published at home and abroad mainly focus on the guidance of the overall treatment decisions and plans,and relevant clinical guidelines abroad lacks progress in surgical treatment of rib fractures in recent years. Therefore,the Chinese Society of Traumatology affiliated to Chinese Medical Association and Chinese College of Trauma Surgeons affiliated to Chinese Medical Doctor Association,in conjunction with national multidisciplinary experts,formulate the Chinese Consensus for Surgical Treatment of Traumatic Rib Fractures(2021)following the principle of evidence-based medicine,scientific nature and practicality. This expert consensus puts forward some clear,applicable,and graded recommendations from aspects of preoperative imaging evaluation,surgical indications,timing of surgery,surgical methods,rib fracture sites for surgical fixation,internal fixation methods and material selections,treatment of combined injuries in rib fractures,in order to provide references for surgical treatment of traumatic rib fractures.

During coronavirus disease 2019 epidemic, the treatment of severe trauma has been impacted. The Consensus on emergency surgery and infection prevention and control for severe trauma patients with 2019 novel corona virus pneumonia was published online on February 12, 2020, providing a strong guidance for the emergency treatment of severe trauma and the self-protection of medical staffs in the early stage of the epidemic. With the Joint Prevention and Control Mechanism of the State Council renaming "novel coronavirus pneumonia" to "novel coronavirus infection" and the infection being managed with measures against class B infectious diseases since January 8, 2023, the consensus published in 2020 is no longer applicable to the emergency treatment of severe trauma in the new stage of epidemic prevention and control. In this context, led by the Chinese Traumatology Association, Chinese Trauma Surgeon Association, Trauma Medicine Branch of Chinese International Exchange and Promotive Association for Medical and Health Care, and Editorial Board of Chinese Journal of Traumatology, the Chinese expert consensus on emergency surgery for severe trauma and infection prevention during coronavirus disease 2019 epidemic ( version 2023) is formulated to ensure the effectiveness and safety in the treatment of severe trauma in the new stage. Based on the policy of the Joint Prevention and Control Mechanism of the State Council and by using evidence-based medical evidence as well as Delphi expert consultation and voting, 16 recommendations are put forward from the four aspects of the related definitions, infection prevention, preoperative assessment and preparation, emergency operation and postoperative management, hoping to provide a reference for severe trauma care in the new stage of the epidemic prevention and control.
