Patients with pathological tracheal loss more than a certain length may need tracheal transplantation.Traditional natural tissue and autologous tissue have failed to produce satisfactory clinical outcomes to replace the trachea because of local infection，tracheal stenosis，tracheomalacia，immune rejection et al. In recent years，the emergence oftissue engineering trachea provides a new idea for tracheal transplantation. But scientists have not yet reached a consensus about how to choose ideal extracellular matrix to construct tissue engineering trachea. At present research and applicationof tissue engineering trachea，extracellular matrices mainly include allogenic trachea，allogenic aorta and biologicalcomposite materials. Each allogenic matrix or biological composite material has its own advantages and disadvantages. Therefore，this article mainly summarizes recent application and research progress of extracellular matrix in long segmental tracheal defect and its future perspective.
Objective To summarize the recent research situation and progress of decellularized matrix in tissue engineered trachea transplantation and to forecast the possible perspects. Methods Recent original articles about study and application for decellularized matrix in tissue engineered trachea were reviewed. The application and study of different decellularized matrices involved in animals or patients with tracheal lesions were elaborated. Results Decellularized matrices researched and applied in tissue engineered trachea include jejunum, urinary bladder, aorta, and trachea. Conclusion Decellularized urinary bladder matrix and jejunal matrix appears to be efficacious method for the patch repair of partial circumferential tracheal defects. The application of decellularized aortic matrix may need more study, and decellularized tracheal matrix has a bright future in long tracheal defects.

Objective To compare the clinical efficacy and safety of suturesuspension single hole laparoscopic cholecystectomy and traditional laparoscopic cholecystectomy (LC) in the treatment of gallbladder disease. Methods A total of 86 cases who got treatment in our hospital from February 2014 to July 2015 were collected prospectively, and then 86 cases were divided into 2 groups: 43 cases of control group underwent LC and 43 cases of experimental group underwent suturesuspension single hole laparoscopic cholecystectomy. Clinical efficacy and safety of the two groups were compared. Results ① Complication. No one suffered from bile duct injury, bile leakage, bile duct stricture, and umbilical hernia; but there were 2 cases suffered from complications in control group, including 1 case of abdominal pain and 1 case of bloating, and the morbidity was 4.65% (2/43). The morbidity of experimental group was 0, there was no significant difference between the 2 groups in the morbidity (P>0.05). During the follow-up period, 1 case suffered from long-term compilation in experimental group, and 2 cases in normal group, there was no significant difference in the long-term complication between the 2 groups (P>0.05). ② Operation and hospitalization. The blood loss and operation time in the experimental group were lower than those of the control group (P<0.05), but there was no significant difference in the hospital stay and hospitalization cost between the 2 groups (P>0.05). ③ Postoperative electrolytes, liver and kidney function. The levels of Na+ and K+ in the experimental group were higher than those of the control group (P<0.05), and the levels of alanine aminotransferase and aspartate aminotransferase were lower than those of control group (P<0.01), but there was no significant difference in the blood urea nitrogen and serum creatinine between the 2 groups (P>0.05). ④ The recovery of gastrointestinal function after surgery. The anal exhaust time and bowel sounds recovery time in experimental group were shorter than those of the control group (P<0.01). Conclusion Suturesus-pension single hole laparoscopic cholecystectomy in the treatment of gallbladder disease is safe, effective, and minimally invasive, and it has little disturbance on gastrointestinal function and liver function, which is worthy of clinical application.
Objective To explore clinical effect and safety of rivaroxaban in treatment of acute pulmonary thromboembolism at moderate risk with deep vein thrombosis of lower limbs. Methods The clinical data of 60 patients with acute pulmonary thromboembolism at moderate risk with deep vein thrombosis of lower limbs, collected from January 2010 to March 2017 in Hunan Provincial People’s Hospital, were retrospectively analyzed. According to the different treatment, these patients were randomly divided into a rivaroxaban group and a control group (traditional warfarin anticoagulation), with 30 patients in each group. The clinical effect and safety were compared between two groups on the 10th day, 20th day and 30th day after treatment. Results Compared with the control group, maximum short axis diameter, ratio of right and left ventricles, systolic pulmonary artery pressure, and main pulmonary artery diameter measured by CTPA and echocardiography in the rivaroxaban group were not significantly different on the 10th day, 20th day and 30th day after treatment. However, the intragroup differences were statistically significant at different timepoint (P<0.05). Levels of N-terminal-pro-brain natriuretic peptide of two groups after treatment were significantly reduced on the 10th day, 20th day and 30th day after treatment, and the values of PO2 were significantly increased on the 10th day and 20th day after treatment (P<0.05), but no significant differences were found in the values of PO2 on 20th day and 30th day after treatment. D-dimer in the two groups was obviously increased on the 10th day after treatment but significantly declined on the 20th day and 30th day after treatment (all P<0.05). These changes were predominant in the rivaroxaban group. Conclusion Rivaroxaban is effective and safe for acute pulmonary thromboembolism at moderate risk with deep vein thrombosis of lower limbs, and worthy of clinical implementation and application.
Objective To review the clinical features and trend in antimicrobial resistance of Acinetobacter baumannii (A. baumannii) bloodstream infections. Methods Retrospective analysis was performed by collecting data of underlying diseases, potential risk factors, clinical characteristics, blood test results, Acute Physiology and Chronic Health EvaluationⅡ (APACHEⅡ) scores at onset, bacterial resistance to antibiotics and antimicrobial therapy were collected in Hunan Provincial People’s Hospital from January 2010 to June 2016. Results There were 114 non-duplicated A. baumannii complex blood isolates identified in this research. All patients had at least one underlying disease and accepted at least one surgery or invasive operation within the past 14 days. Multidrug-resistant A. baumannii (MDRAB) was isolated from 89 (78.1%) patients. Of the 114 strains of A. baumannii, 12.3% were resistant to tigecycline, 55.3% to amikacin and 61.4% to cefoperazone-sulbactam. The overall mortality was 51.8% (59/114). The patients with MDRAB had higher mortality rate than those with non-MDRAB (62.9% vs. 12.0%, χ2=20.268, P<0.001). With higher incidence of being in the intensive care unit, intubation/tracheotomy and increased APACHEⅡ score among patients with MDRAB bacteremia (P<0.05). Compared with subjects treated with tigecycline based regimen, those treated with non tigecycline for multidrug resistantA. baumannii had a higher mortality (64.8% vs. 60.0%) but there was no statistical significance (P>0.05). Conclusions The isolated A. baumannii are mainly multidrug resistant and with high mortality. Being in the intensive care unit, increased APACHEⅡ score and intubation/tracheotomy were risk factors for higher mortality among patients with MDRAB bloodstream infection. Tigecycline based regimen doesn’t improve patients’ prognosis.
