ObjectiveTo evaluate the role of cardiopulmonary bypass (CPB) technique in the treatment of the abdominal soft tissue tumor (ASTT). MethodClinical data of 9 patients with ASTT who underwent CPB-aided resection in zhongshan Hospital of Fudan University from April 2011 to December 2015 were analyzed retrospectively. ResultsAll patients were performed complete resection of tumor, without perioperative death. Six patients received complete CPB technique and other 3 patients received partial CPB technique. In establishment of CPB, patterns of arterial perfusion included the ascending aorta (n=6) and femoral artery (n=3); patterns of venous drainage included the inferior vena cava (n=2), superior vena cava (n=6), femoral vein (n=2), and jugular vein (n=3). Among of them, 7 patients were diagnosed as intravenous leiomyomatosis, 1 patient was diagnosed as small round cell malignant tumor, and another 1 patient was diagnosed as leiomyosarcoma. Two patients occurred postoperative complications, 1 patient was duodenal fistula, with conservative treatment to heal; another 1 patient was inferior vena cava thrombosis, with treatment of placement of the inferior vena cava filter. Nine patients received follow-up, and follow-up time was 1-57 months (the median time was 4-month), and the survival rate was 100%, no one suffered from recurrence. ConclusionsFor some patients with complicated ASTT, CPB technique can provide chance to completely resect the tumors.

Objective To summarize the application and prospect of susceptibility weighted imaging （SWI） in diagnosis of hepatic disease. Methods The application of SWI in diagnosis of hepatic disease was analyzed retrospectively via reviewed the literatures home and abroad, and to look forward to the future of the clinical values of SWI. Results A number of hepatic diseases such as cirrhosis, hematochromatosis， and malignant tumors could induce iron overload in hepatic cell and Kuffper cell. Because of SWI is sensitive to vein， vascular abnormality, haemorrhage （including all kinds of metabolities after bleeding）， iron overload， calcification, and so on, so the use of SWI in hepatic disease is explored continually. Conclusions SWI may be a new method for diagnosis of hepatic disease, which can supply more valuable information for clinician.
Objective To observe the clinical effect of the human tissue engineered activeskin (ActivSkin) with full thickness on the donor site of the split thickness skin graft. Methods Nine patients with 18 wounds of the donor sites, and every p atient had 2 wounds. The wounds of each patient were randomly assigned to the therapy group and the control group. Autocontrol observation was performed. Nine donor sites of the split thickness skin graft were repaired with ActivSkin in the therapy group. Nine donor sites of the split thickness skin graft were repaired with the vash oil gauze in the control group. The wound pain, the time to complete closure, and the ratio of the complete healing in the ActivSkin therapy gro up was measured and compared with those in the control group. The donor sites of the split thickness skin graft were assessed at 180 days of the follow-up visit . Results The wound pain was obviously reduced after the harvest ing of the skin grafts in the therapy group. The time to complete closure on the donor sites of the split thickness skin graft was significantly shorter in the ActivSkin therap y group than in the control group (9.67±2.92 d vs.16.56±2.96 d, Plt;0.05 ). Both the ratios of the complete healing in the ActivSkin therapy group and the control group were 100%（Pgt;0.05）. The subsequent results showed that neit her the blister nor the residual wound occurred with an alleviated scar after the Ac tivSkin treatment. Conclusion ActivSkin can promote wound closure, prevent blister and residual wound, and alleviate scarring on the donor sites of the splitthickness skin graft after the ActivSkin treatment.
ObjectiveTo explore the innovative application and effect of lead-type close medical consortium under the epidemic situation of coronavirus disease 2019 (COVID-19).MethodsDuring the epidemic of COVID-19, Jintang First People’s Hospital implemented a series of innovative countermeasures under the guidance of West China Hospital of Sichuan University, the leading hospital of a lead-type close medical consortium. To verify the implementation effect of the countermeasures, the patient satisfaction questionnaire and medical personnel satisfaction questionnaire were administered in confirmed or suspected COVID-19 patients and anti-epidemic healthcare workers. The relevant health economic indicators were extracted through the hospital information system for descriptive analysis.ResultsA total of 16 patients were included, including 10 confirmed patients and 6 suspected patients. The median score of patient satisfaction was 66. All patients were cured and discharged. A total of 56 healthcare workers were included, including 18 doctors and 38 nurses, with a median satisfaction score of 81. The average length of hospital stay of patients was 11.00 d, the average hospitalization cost was 5 117.35 yuan; the average drug cost was 1 099.95 yuan, accounted for 21.49%; the average material cost was 38.63 yuan, accounted for 0.75%.ConclusionsThe innovative application of the lead-type close medical consortium in the treatment of patients with COVID-19 plays an important role in the prevention and control of epidemic, and has achieved remarkable results in patients treatment, patients satisfaction, and hospital management.

ObjectiveTo investigate the effect of using hemoglobin-revised trauma score (HB-RTS) on predicting mortality risk in trunk injury patients. MethodsAccording to case control study rules, medical records of patients with trunk injury who were treated between July 2011 and October 2013, were collected. Patients were divided into two groups according to their survival prognosis within 28 days. The HB-RTS, revised trauma score (RTS), and injury severity score (ISS) of the two groups were calculated. The receiver operating characteristic (ROC) curve was drawn, and the area under the curve (AUC) and Youden's index were calculated. And then, we selected the optimal cutoff value using HB-RTS and RTS to predict the trunk injury patients' mortality and calculated their sensitivity, specificity, and accuracy. In the end, the correlation of ISS with HB-RTS and RTS using linear correlation analysis method was analyzed. ResultsBesides RTS, HB-RTS and ISS in the death group were statistically significant higher than that in the survival group. The AUC of HB-RTS and RTS of the two groups were 0.922 and 0.888, respectively. The sensitivity of HB-RTS and RTS were 91.5% and 83%; and the specificity of HB-RTS and RTS were 95.7% and 76.6%, respectively. The correlation of HB-RTS and ISS was -0.592, while the correlation of RTS and ISS was 0.585. ConclusionCompared to RTS, ROC of HB-RTS is enlarged, the specificity is increased, and the sensitivity is decreased. HB-RTS has stronger correlation with ISS than with RTS. The predictive effect of HB-RTS is higher than RTS in predicting mortality of trunk injury patients.
