OBJECTIVE To explore the construction of mind map by clinical pharmacists for the consultation of pulmonary nocardiosis and its application in clinical practice， and to provide reference for promoting the correct selection of nocardiosis treatment drugs in clinical practice and ensuring drug safety and efficacy. METHODS A total of 7 patients with Nocardia pulmonary infection from January 2017 to April 2022 in our hospital were collected. Based on evidence-based medicine， a consultation mind map （mainly including understanding the medical history， identifying infectious bacteria， identifying risk factors， developing treatment plans， and conducting evaluations） was constructed to address the difficulties of large differences in drug sensitivity among different strains of Nocardia and numerous adverse reactions of Compound sulfamethoxazole as a first-line drug. The treatment plan was developed for 7 patients with pulmonary nocardiosis， and whole-process pharmaceutical care was provided. RESULTS Combined with the mind map， different antibiotic combination regimens were given according to the drug sensitivity results of Nocardia， the different species of Nocardia， and the patient’s allergy history. Among them， 4 cases were treated with imipenem cilastatin， the patients receiving Compound sulfamethoxazole and linezolid for a long time were given full pharmaceutical care， and the adverse drug reactions were timely treated.CONCLUSIONS Clinical pharmacists apply the consultation mind map of pulmonary nocardiosis to the treatment of inpatients， take advantage of pharmacy， participate in clinical drug therapy， and really play a role in the clinical treatment team so as to promote rational drug use.

ObjectiveTo analyze the occurrence of sport injury in Paralympic athletes during the Summer or Winter Paralympic Games, as well as the risk factors for sport injuries and possible interventions. MethodsThe literatures related to sport injuries of Paralympic athletes were searched in PubMed, Web of Science, EBSCO and CNKI from January, 2013 to July, 2022, and a scoping review of the retrieved literature was performed. ResultsFinally, eight English articles from China, Sweden, South Africa, Poland and the United States were included, involving 4 769 atheletes. They included one interview study, five survey studies, one retrospective study and one prospective cohort study, which were mainly from journals in the fields of sport medicine, adaptive sport and sport science, and the publication date was mainly from 2016 to 2022. The types of disability of Paralympic athletes mainly involved physical disability (upper and lower limb amputation, cerebral palsy, spinal cord injury, poliomyelitis, dysplasia and neuromuscular dystrophy, central nervous system injury, myelomeningocele, etc.), intellectual disability and visual disability. The incidence of sport injury was high in Paralympic athletes, and most of the injury occured during competitions. Acute injury, chronic overuse injury and chronic to acute injury were the three most common types of injury. Sports injuries mainly involved head and neck, upper limbs (shoulders, upper arms/forearms, elbows, wrists and fingers), trunk (abdomen, back and waist), and lower limbs (hips/groin, thighs, knees, calves, ankles and toes). Risk factors for sport injuries in Paralympic athletes mainly included previous injury history, illness, fatigue and decreased physical strength, spasticity and muscle weakness; emotional states of inattention or distraction, excessive anxiety or excitement; improper exercise training methods, lack of knowledge related to sport training and injury prevention, and motor skill deficiencies; weather, competition venues, sport facilities, use of equipment and assistive devices, age factors, etc. Injuries of Paralympic athletes could be prevented by providing rehabilitation services for Paralympic athletes, optimizing training design, conducting collective training for coaches and athletes on various types of injuries, conducting research related to sport injuries of disabled athletes, formulating prevention programs and strategies, improving the physical fitness and sport skills of Paralympic athletes, improving emergency treatment techniques for injuries, and strengthening coordination and governance structures between sport medicine and rehabilitation therapists. ConclusionThe incidence of sport injury is high in Paralympic athletes. Chronic overuse injury is the most common injury type, and the injuries most involve head, neck and upper extremities. The risk factors for sport injuries of Paralympic athletes mainly involve physical function, psychological, activities and participation, environment and other factors. The main intervention strategies include providing emergency treatment intervention and monitoring services, sport medicine treatment and rehabilitation, guidance and specialized support, and health education on sport injury prevention.

Discipline construction is the core of hospital development. Under the initiative to build " first-class universities and disciplines" , in order to speed up the construction of first-class hospitals, a university-affiliated hospital carried out discipline construction management by optimizing top-level design, discipline differentiation development, evaluation index system construction and strengthening its application, and carrying out process management in the form of project system.In 2018, the hospital levelled its individual disciplines as leading ones, advantageous ones, backbone ones, backbone promising ones and potential ones, each granted with corresponding funding support. Medians of the disciplinary construction scoring of disciplines at various levels from 2015 to 2018 were used as the standard scoring in examinations in the next two years(2019 and 2020), guiding the disciplines to upgrade their design for discipline construction index system. The appraisal of discipline construction in 2019 and 2020 found 38 disciplines up to the standard scoring, including 16 twice higher than the scoring, while only 7 scored lower than the standard one. The hospital has made stage-based progress in discipline reputation, faculty, science research and social contribution, initially achieving effective guidance of disciplines of the hospital.

Objective:To summarize the anesthesia management of living small bowel transplantation.Methods:Severn patients undergoing living and allogeneic small bowel transplantation for the first time were selected.The intraoperative hemodynamics, indexes of blood gas analysis, body temperature and blood transfusion and volume of liquid infused were analyzed.Postoperative outcomes were tracked.Results:Six cases survived and were successfully discharged from hospital successfully, and one patient died.In the operation room, 71% patients were successfully extubated after surgery.Compared with the values during anatomical separation period, Hb during vascular anastomosis and intestinal reconstruction periods and concentration of Ca 2+ during intestinal reconstruction period were significantly decreased, and the blood glucose concentration during vascular anastomosis period were increased ( P<0.05 or 0.01). Compared with the values during vascular anastomosis period, the blood glucose concentration was increased significantly during intestinal reconstruction period ( P<0.05). Crystalloid solution (57±30) ml/kg and colloid solution which mainly containing 20% albumin (15±13) ml/kg were infused mainly during anatomical separation and vascular anastomosis periods in all the patients. Conclusion:The condition of successful living small bowel transplantation is fully evaluation and preparation before surgery.Intravenous-inhalational anesthesia combined with transverses abdominis plane block and rational infusion of colloid solution with vasoactive drugs to maintain hemodynamics stability and monitor blood gas, body temperature, active adjustment of electrolytes and internal environment and stable body temperature can be helpful in maintaining perioperative stable vital signs during the perioperative period, removing the tracheal tube early at the end of surgery, and reducing the development of postoperative complications in patients undergoing living small bowel transplantation.

Objective:To investigate the clinical application effect of latissimus dorsi muscle flap in reconstruction of muscle strength around shoulder after electric burns.Methods:From March 2014 to September 2020, 13 patients with electric burns and severe injury around shoulder were admitted to the First Affiliated Hospital of Air Force Medical University, including 11 males and 2 females, aged 19-55 years. A retrospective observational study was conducted. The left upper limbs were injured in 8 cases, and the right upper limbs were injured in 5 cases, all with eschar wounds of Ⅲ-Ⅳ degree. Among which, there were biceps defects in 6 cases, deltoid defects in 3 cases, triceps defects in 2 cases, and composite defects of multiple muscles around shoulder in 2 cases. The surgery was carried out in two stages. In stage Ⅰ, debridement and exploration of electric burn wounds around shoulders were conducted to preserve local tissue and save the limb as much as possible on the premise of guaranteeing the stability of the body condition. After the last debridement, the wound area was from 10 cm×6 cm to 40 cm×15 cm, the muscle defect area was from 8 cm×4 cm to 19 cm×12 cm, and the humerus was exposed in 7 patients. In stage Ⅱ, according to the residual limb defect degree, muscle reconstruction around shoulder was conducted with the latissimus dorsi muscle flap, and area of the latissimus dorsi muscle flap was 15 cm×6 cm to 20 cm×18 cm. The residual wounds were repaired with autologous split-thickness skin grafts of head, and the donor sites of muscle flaps were sutured directly. The survivals of the muscle flaps and wounds closure post operation, and the appearances of the donor sites and recipient sites during follow-up were observed. At the last follow-up, the shoulder joint function was evaluated using the trial standard for the evaluation of the functions of the upper limbs of the Hand Surgery Society of the Chinese Medical Association, and the satisfaction degrees of patients for appearance and function recoveries of shoulder were investigated by self-made questionnaire with reference to the concise test scoring system of shoulder joint.Results:All of the 13 muscle flaps around shoulder survived after surgery. Two patients had residual wounds in the skin grafting area, the wound in one of the patients was healed after dressing change, and the wound in the other 1 patient was healed with the second autologous split-thickness skin grafting on head after dressing change. During follow-up of 6 to 18 months for all the patients, the muscle flaps of patients were full in appearance and not bloated, and atrophic scar in the repaired area was soft in texture and closed with normal skin around. Linear suture scars were left in the donor sites of muscle flaps, which did not affect the overall appearance. At the last follow-up, the active abduction range of the shoulder joint was 60-90°, upward lift on 120-180°, muscle strength recovered to level Ⅳ and above in 8 cases and to level Ⅲ in 5 cases, and the shoulder joint function was evaluated as excellent in 8 cases and good in 5 cases; 10 patients were very satisfied and 3 patients were satisfied with the appearance and function recovery of the shoulders.Conclusions:The application of latissimus dorsi muscle flap provides a better choice for the muscle strength reconstruction around shoulder after electric burns, with good appearance of the operative areas and ideal prognosis of upper limb function.

Objective:To compare the clinical effects of continuous negative-pressure wound therapy (NPWT) and conventional pressure dressing at at hard-to-fix sites after split-thickness skin grafting.Methods:From September 2017 to August 2019, 129 patients who met the inclusion criteria and had spilt-thickness skin grafting at hard-to-fix sites were admitted to the First Affiliated Hospital of Air Force Medical University and included in this retrospective cohort study. The patients were divided into NPWT group (67 patients, 41 males and 26 females, aged (32±6) years) and conventional pressure dressing group (62 patients, 37 males and 25 females, aged (30±5) years) according to whether the hard-to-fix sites were applied with NPWT after spilt-thickness skin grafting. After debridement and spilt-thickness skin grafting at hard-to-fix sites in patients of 2 groups, the wounds of patients in conventional pressure dressing group were applied with conventional pressure bandaging after being filled with dry gauze; for the wounds of patients in NPWT group, the semi-permeable membrane was pasted and sealed for continuous negative pressure suction after filled with dry gauze and placed the drainage foam or drainage tube, with the negative pressure ranging from -16.6 to -9.9 kPa. The bandage was opened during the first dressing change on the 5th day after surgery in NPWT group and on the 7th day after surgery in conventional pressure dressing group. The skin graft surviving area and proportion, the area and proportion of hematoma, the incidence of common complications of skin graft were observed and calculated. The times of postoperative dressing change and the length of hospital stay were counted. Data were statistically analyzed with two independent sample t test, Cochran & Cox approximate t test, chi-square test, and Fisher′s exact probability test. Results:(1) At the first dressing change, the skin graft surviving area of patients in NPWT group was (420±94) cm 2, which was significantly larger than (322±97) cm 2 in conventional pressure dressing group ( t′=12.33, P<0.01); the skin graft surviving area proportion of patients in NPWT group was (97.0±2.3)%, which was significantly higher than (74.4±4.8)% in conventional pressure dressing group ( t′=50.11, P<0.01). (2) At the first dressing change, the skin hematoma area of patients in conventional pressure dressing group was (31.7±10.1) cm 2, which was significantly larger than (3.2±0.7) cm 2 in NPWT group ( t′=23.04, P<0.01); the skin hematoma area proportion of patients in conventional pressure dressing group was (7.3±2.3)%, which was significantly higher than (0.7±0.3)% in NPWT group ( t′=76.21, P<0.01). (3) At the first dressing change, there was 1 case of skin movement and no case of skin graft edge tear in NPWT group with an incidence of 1.5% (1/67). In the conventional pressure dressing group, there were 4 cases of skin movement and 2 cases of skin graft edge tear with an incidence of 9.7% (6/62), P<0.05. The incidence of complication of skin graft of patients in NPWT group was significantly lower than that in conventional pressure dressing group ( P<0.05). (4) The times of postoperative dressing change of patients in NPWT group was significantly less than that in conventional pressure dressing group ( t=7.93, P<0.01). The postoperative length of hospital stay in NPWT group was significantly less than that in conventional pressure dressing group ( t=11.71, P<0.01). Conclusions:Continuous NPWT can effectively promote wound healing, improve the survival rate of skin graft, reduce the incidence of complications after skin grafting, and shorten the length of hospital stay in split-thickness skin grafting at hard-to-fix sites.
