Objective:To investigate the feasibility and safety of endovascular repair for traumatic thoracic aortic pseudoaneurysm.Methods:From Oct 2015 to Oct 2018, the clinical and followup data of 7 patients diagnosed as traumatic thoracic aortic pseudoaneurysm in Fuwai Hospital of Chinese Academy of Medical Sciences were analyzed retrospectively.Results:The patients average age was (51.2±11.0) years old. All patients underwent surgery in the hybrid operating room under general anesthesia. Two did thoracic endovascular aortic repair (TEVAR), three did TEVAR combined with chimney technique to reconstruct the left subclavian artery, and 1 had TEVAR combined with fenestration to reconstruct the left subclavian artery. One did TEVAR with left common carotid artery and left subclavian artery bypass. The mean operative time was (90.1±27.4) min, the mean postoperative hospital stay was (8.9±3.7) d, and the mean postoperative follow-up time was 42.4 months. All the patients received CTA reexamination of the aorta after 1, 6, 12 months and yearly thereafter. TypeⅠendoleak was found in one patient with chimney technique to reconstruct of left subclavian artery after operation. CT showed that the type Ⅰ endoleak disappeared 6 months after operation. There was no death, paraplegia or stroke during the perioperative period and follow-up period, and there was no aortic related reintervention.Conclusion:TEVAR is a safe and effective method for the treatment of traumatic pseudoaneurysm of thoracic aorta, and the early and mid-term results were satisfactory.

Objective The primary goal of this work is to discuss the molecular mechanism of multi-drug resistant Pseudomonas spp. resistance to carbapenam and aminoglycoside antibiotics. Methods From June 2012 to March 2013, six strains of P. aeruginosa and P. putida producing carbapenemasefrom 4 different district were collected. Species identification was performed using VITEK-2 compact system and by sequencing of 16S rDNA amplicons. Minimum inhibitory concentrations were determined by E-test method. Production of carbapenemase were detected by Carba NP method. Carbapenemase genes and aminoglycoside 16s rRNAmethylase genes were screened by PCR, and their subtypes combined with their immediate genetic context were worked out by assemble the sequence of overlapped PCR amplicons. SpeI-PFGE (Pulse field gel electrophoresis after SpeI enzyme digestion) were conducted to evaluate their clonal relatedness. S1-PFGE (Pulse field gel electrophoresis after S1 enzyme digestion) were conducted to conform the relatedness of plasmids they carried. Results Three multidrug resistant P. aeruginosa and three P. putida, were all positive for Carba NP test and conformed producing class B carbapenemase. PCR screening followed by sequencing confirmed carriage of blaIMP-45 and armA, which confer resistance to β-lactams (except aztreonam) and aminoglycosides. These two genes co-located in a Tn1548-associatedregion. SpeI-PFGE disclosed that these isolates were not clonal closely related to each other, except two P. aeruginosa isolates were clonal related. S1-PFGE results showed that these isolates all carried plasmids of large size (300-600 kb). Conclusions This study showed that Pseudomonas spp. isolates co-carried blaIMP-45 and armA were disseminated in clinical settings. Spread of these genes may attribute to horizontal gene transfer of related entities.

Objective To observe the effect of transversus abdominis plane block(TAPB)combined with patients controlled intravenous analgesia(PCIA)on the analgesia of patients after splenectomy.Methods A retrospective study method was conducted.A total of 63 patients who underwent splenectomy+pericardial vascular dissection in the department of general surgery of Nanchang No.9 Hospital from January to December 2021 were selected as the study objects.The patients were divided into TAPB combined with PCIA group(33 cases)and alone PICA group(30 cases)according to different postoperative analgesia techniques,and the postoperative analgesia effect was compared between the two groups.Results There was no significant difference between the two groups in sex,age,height,body mass,Child-Pugh grade and American Society of Anesthesiologists(ASA)grade.The operation time,intraoperative blood loss and intraoperative blood transfusion volume in TAPB combined with PCIA group were increased compared with alone PICA group[operation time(minutes):85.0(32.5)vs.82.5(40.0),intraoperative blood loss(mL):500(300)vs.425(500),intraoperative blood transfusion(mL):400(300)vs.300(525)],the incidence of postoperative abdominal infection and incisional infection tended to decrease compared with alone PICA group[abdominal infection:18.2％(6/33)vs.20.0％(6/30),incisional infection:21.2％(7/330)vs.23.3％(7/30)],but there was no significant difference between the two groups(both P>0.05).The visual analogue score(VAS)decreased gradually over time in both groups,and VAS in TAPB combined with PCIA group was significantly lower than that in PICA group at 6,12,24,48 and 72 hours after operation[4.0(1.0)vs.6.0(3.0),3.0(2.0)vs.4.0(2.0),2.0(1.5)vs 3.5(1.5),1.0(1.0)vs.2.0(1.5),1.0(1.0)vs.2.0(2.0),all P<0.05],the total number of PCIA compressions in TAPB combined with PCIA group was significantly lower than that of alone PICA group(times:2.64±1.19 vs.3.67±1.67,P<0.05).Conclusion The analgesic effect of TAPB combined with PCIA after splenectomy and devascularization is better than that of PCIA alone.

Lower extremity deep vein thrombosis (DVT) is one of the main complications in patients with traumatic fractures, and for severe patients, the DVT can even affect arterial blood supply, resulting in insufficient limb blood supply. If the thrombus breaks off, pulmonary embolism may occur, with a high mortality. The treatment and rehabilitation strategies of thrombosis in patients with lower extremity fractures have its particularity. DVT in traumatic fractures patients has attracted extensive attention and been largely studied, and the measures for prevention and treatment of DVT are constantly developing. In recent years, a series of thrombosis prevention and treatment guidelines have been updated at home and abroad, but there are still many doubts about the prevention and treatment of DVT in patients with different traumatic fractures. Accordingly, on the basis of summarizing the latest evidence-based medical evidence at home and abroad and the clinical experience of the majority of experts, the authors summarize the clinical treatment and prevention protocols for DVT in patients with traumatic fractures, and make this consensus on the examination and assessment, treatment, prevention and preventive measures for DVT in patients with different fractures so as to provide a practicable approach suitable for China ′s national conditions and improve the prognosis and the life quality of patients.

TSCI have dyskinesia and sensory disturbance that can cause various life-threaten complications. The patients with traumatic spinal cord injury (TSCI), seriously affecting the quality of life of patients. Based on the epidemiology of TSCI and domestic and foreign literatures as well as expert investigations, this expert consensus reviews the definition, injury classification, rehabilitation assessment, rehabilitation strategies and rehabilitation measures of TSCI so as to provide early standardized rehabilitation treatment methods for TSCI.

Periarticular fracture of the shoulder is a common type of fractures in the elderly. Postoperative adverse events such as internal fixation failure, humeral head ischemic necrosis and upper limb dysfunction occur frequently, which seriously endangers the exercise and health of the elderly. Compared with the fracture with normal bone mass, the osteoporotic periarticular fracture of the shoulder is complicated with slow healing and poor rehabilitation, so the clinical management becomes more difficult. At present, there is no targeted guideline or consensus for this type of fracture in China. In such context, experts from Youth Osteoporosis Group of Chinese Orthopedic Association, Orthopedic Expert Committee of Geriatrics Branch of Chinese Association of Gerontology and Geriatrics, Osteoporosis Group of Youth Committee of Chinese Association of Orthopedic Surgeons and Osteoporosis Committee of Shanghai Association of Chinese Integrative Medicine developed the Chinese expert consensus on the diagnosis and treatment of osteoporotic periarticular fracture of the shoulder in the elderly ( version 2023). Nine recommendations were put forward from the aspects of diagnosis, treatment strategies and rehabilitation of osteoporotic periarticular fracture of the shoulder, hoping to promote the standardized, systematic and personalized diagnosis and treatment concept and improve functional outcomes and quality of life in elderly patients with osteoporotic periarticular fracture of the shoulder.
