OBJECTIVE: To study the effects ethanol extract of Zingiber officinale against myocardial ischemia-reperfusion injury in rats. METHODS: 50 female SD rats were randomly divided into sham group, model group, ethanol extract of Z. officinale groups (low, medium, high-dose group). Acute regional myocardial ischemia-reperfusion injury model was induced with ligation of rat heart left anterior descending coronary artery for 30 min and 90 min of reperfusion. The content of malondialdehyde (MDA) and activity of superoxide dismutase (SOD) were measured while transmission electron microscopy (TEM) was applied to detect the changes in myocardial ultrastructure. RESULTS: As compared with sham group, the content of MDA in model group was significantly increased but the activity of SOD was decreased (P

Objective To investigate the role of ISS and new injury severity score (NISS) in evaluation of complications and treatment outcomes in the multiple trauma patients combined with severe chest trauma.Methods AIS-2005 was used to carry out retrospective analysis of the 1 377 multiple trauma patients combined with severe chest trauma (thoracic AIS≥3 points) treated at Chongqing Emergency Medical Center from January 2005 to January 2011.In the meantime,the related NISS and ISS were calculated and their relations with mortality were analyzed.Results The overall healing,mortality and complication rate were 93.2%,6.8% and 28.5% respectively.Both the ISSN and ISS had positive correlation with morbidity of complications ( r =0.569,P <0.01 ;r =0.442,P <0.01 ) and mortality (r =0.693,P < 0.01 ; r =0.774,P < 0.01 ),but a stronger relevance was demonstrated between NISS and morbidity of complications and between ISS and mortality rate.NISS showed a higher sensitivity but less specificity than ISS in prediction of morbidity of complications (P < 0.01 ),and NISS was not superior to ISS in prediction of mortality ( P > 0.05 ).Conclusions Both NISS and ISS work well in evaluating the complications and treatment outcomes in multiple trauma patients combined with severe chest trauma.Thus,NISS should be applied for prediction of complication occurrence and ISS for treatment outcomes to maximize the prediction accuracy.

Objective:To explore the surgical method and therapeutic effect of repairing thumb pulp defect with pedicled transposition of radial proper palmar digital artery flap of middle finger.Methods:Since June, 2006 to May, 2020, 17 cases(17 fingers) with thumb pulp defect were repaired by pedicled transposition of radial proper palmar digital artery flap of middle finger. The sizes of flap ranged from 1.5 cm × 1.5 cm to 4.2 cm × 2.0 cm. The antegrade pedicled flap of radial proper palmar digital artery of middle finger was used in 2 cases and the retrograde pedicled flap of middle finger was used in 15 cases. After the flap was resected, the donor sites were covered with a medium thickness skin graft transferred from the wrist or elbow. The skin graft did not need to be packed. The dorsal branch of the digital nerve was included in the flap and it was anastomosed with the proper nerve of the injured thumb stump. After 16-22 days of the operation, the pedicles were cut off. The patients were instructed to perform digit function exercise after the pedicle was cut off. After the operation, the patients were included in regularly follow-up through outpatient visit, telephone or WeChat interview. The appearance and sensation of the thumb and finger pulps and the function recovery of the thumb and finger joints were observed through the followed-ups.Results:All 17 flaps and donor site skin grafts survived over 3 to 32 months of follow-up. The flaps achieved good texture and natural appearance. The TPD recovered to 5~11 mm. According to the Michigan Hand Function Questionnaire, all the 17 patients were very satisfied with the overall appearance and function of the hands. According to TAM, the 17 cases were all in excellent.Conclusion:Repairing thumb pulp defect with radial proper palmar digital artery pedicled flap of middle finger, the flap resection is simple, and the donor site is hidden. The appearance and texture of flap is good. It is a safe, effective and good method.

Osteoporotic vertebral compression fracture (OVCF) can lead to lower back pain and may be even accompanied by scoliosis, neurological dysfunction and other complications, which will affect the daily activities and life quality of patients. Vertebral augmentation is an effective treatment method for OVCF, but it cannot correct unbalance of bone metabolism or improve the osteoporotic status, causing complications like lower back pain, limited spinal activities and vertebral refracture. The post-operative systematic and standardized rehabilitation treatments can improve curative effect and therapeutic efficacy of anti-osteoporosis, reduce risk of vertebral refracture, increase patient compliance and improve quality of life. Since there still lack relevant clinical treatment guidelines for postoperative rehabilitation treatments following vertebral augmentation for OVCF, the current treatments are varied with uneven therapeutic effect. In order to standardize the postoperative rehabilitation treatment, the Spine Trauma Group of the Orthopedic Branch of Chinese Medical Doctor Association organized relevant experts to refer to relevant literature and develop the "Guideline for postoperative rehabilitation treatment following vertebral augmentation for osteoporotic vertebral compression fracture (2022 version)" based on the clinical guidelines published by the American Academy of Orthopedic Surgeons (AAOS) as well as on the principles of scientificity, practicality and advancement. The guideline provided evidence-based recommendations on 10 important issues related to postoperative rehabilitation treatments of OVCF.
