Objective:To explore the effect of laryngeal massage combined with feeding training on swallowing function and quality of life in patients with poststroke swallowing disorders.Methods:From November 2021 to October 2022, convenience sampling was used to select 148 patients with poststroke swallowing disorders in the Department of Neurosurgery and Rehabilitation at the North China University of Science and Technology Affiliated Hospital. The patients were divided into a control group, a laryngeal massage group, a feeding training group, and a combination group using the random number table method, with 37 cases in each group. The control group was given routine nursing, while the laryngeal massage group and feeding training group respectively received laryngeal massage and feeding training on the basis of routine nursing. The combination group underwent laryngeal massage combined with feeding training on the basis of routine nursing. Before and after 2, 4, and 8 weeks of intervention, the Water Swallowing Test, Standardized Swallowing Assessment (SSA), and Chinese version Swallowing Quality of Life Questionnaire (SWAL-QOL) were used to compare the swallowing function and quality of life of four groups of patients with poststroke swallowing disorders.Results:After 2, 4, and 8 weeks of intervention, the Water Swallowing Test rating and efficacy evaluation of the 4 groups of patients with poststroke swallowing disorders were better than those before intervention ( P<0.05). Moreover, the SSA scores decreased compared to before intervention ( P<0.05), and the SWAL-QOL scores increased compared to before intervention ( P<0.05). The Water Swallowing Test efficacy evaluation and SWAL-QOL scores in the combined group were higher than those of the other groups ( P<0.05), while the SSA scores were lower than those of the other groups ( P<0.05) . Conclusions:Laryngeal massage and feeding training can improve the swallowing function and quality of life of patients with poststroke swallowing disorders, and the combination of the 2 interventions has a significant effect.

Objective:To explore the influence of symptom group of stroke patients with exercise disorder on acute stress disorder.Methods:Patients with stroke and motor impairment hospitalized in the Department of Neurology and surgery of North China University of technology from October 2018 to August 2019 were selected as the research objects.The general information of patients, brain injury subscale (BIS) and Stanford acute stress reaction questionnaire (SARSQ) were investigated by questionnaire.Results:A total of 324 patients with stroke and motor disorders were investigated.The demographic characteristics of education, age, degree of motor function, number of combined dysfunction and Activity Of Daily Living Scale(ADL) grade had effects on acute stress disorder, and the differences were statistically significant( P<0.05). The score of acute stress disorder in stroke patients with motor disorders was (99.60±13.69 ) points.From the highest to the lowest symptom group, the scores were obsessive symptom (11.35±2.71), depression (7.44±1.86), hostility (7.23±2.26), somatization (3.69±1.42) and psychosis (2.81±1.09). The results of correlation analysis showed that somatization, depression, obsessiveness, hostility and psychosis were positively correlated with the total score of acute stress disorder and the scores of each dimension ( r=0.164, 0.355, 0.329, 0.298, 0.279, all P<0.05), the symptoms were also positively correlated with all the dimensions of acute stress disorder(all P<0.05). Multiple linear regression analysis showed that age(Regression coefficient=7.682, 95% CI: 4.930-10.435, P<0.001), the number of combined dysfunction(Regression coefficient=3.937, 95% CI: 0.268-7.605, P=0.036), depression(Regression coefficient=1.662, 95% CI: 0.727-2.597, P=0.001) had influence on ASD of stroke patients. Conclusion:The level of acute stress disorder in stroke patients with motor impairment is on the high side, and the characteristics of symptom group are obvious, which has a positive correlation with acute stress disorder.Medical staff should pay attention to the characteristics of symptom group and acute stress reaction level of stroke patients with motor impairment, so as to provide targeted intervention strategies to avoid disease recurrence and improve the quality of life.

Objective:To investigate the clinical effects of Masquelet technique with the transfer of free iliac inguinal flap in reconstruction of infectious bone and soft tissue defect after metacarpal fracture surgery.Methods:From January 2014 to January 2020, 16 patients suffered from infectious bone and soft tissue defect after surgery of metacarpal fracture were treated in Department of Hand Surgery, Institute for Hygiene of Ordnance Industry (Weapon Industry 521 Hospital). Debridement and vacuume sealing drainage (VSD) coverage of wound were carried out in emergency surgery, and Masquelet technique combined with free iliac inguinal flap for reconstruction of infected metacarpal bone defect were performed in sub-emergency surgery. The patients were 14 males and 2 females with an average age of 38 (20-50) years old. Plates were removed in 10 patients and retained in 6 patients. Defects of metacarpal bone ranged from 0.8 cm×0.8 cm×2.0 cm to 1.5 cm×2.0 cm× 5.1 cm in size. Soft tissue defects ranged from 3.6 cm×6.8 cm to 7.8 cm×11.6 cm. Tendon defects were found in all 16 patients. After the primary procedure of Masquelet technique combined with free iliac inguinal flap, routine anti-infection, anticoagulant, antispasmodic and other treatments were offered to all patients. Then all patients were observed by fortnightly reviews. After infection was cleared, the second phase of Masquelet treatment began. The defects of metacarpal bone were reconstructed with autologous cancellous bone grafts, and measures to prevent from infection together with other therapies were offered after the surgery. Follow-up of the second phase surgery was carried out once per 1-2 weeks and then per 2-4 months after bone union. The follow-up review items included: wound infection and necrosis, appearance, shape, texture and sensory recovery of flap. Bone union of infectious metacarpal defect was evaluated, recurrence of infection was closely observed as well as the resorption or nonunion of bone by X-rays. Hand function was assessed according to the Evaluation Trial Standards of Upper Limb Partial Functional of Hand Surgery of Chinese Medical Association. Donor sites healing and functional recovery were also included in the postoperative observation.Results:The follow-up time ranged from 1.5-3.0 (average 2.4) years. There was no necrosis of iliac inguinal flap, no recurrence of infection, and the flaps all healed well. The appearance, shape and texture of flaps were found close to the adjacent skin in all patients. Two-point discriminations (TPD) of the transferred iliac inguinal flaps were at 8-10 mm. X-ray reviews showed that bone union achieved in all patients. The time of bone union were 2.1-3.4 months (2.9 months in average) after bone grafting. There was no bone resorption, infection or nonunion. According to the Evaluation Standard of Upper Limb Partial Functional of Hand Surgery of Chinese Medical Association, 13 patients were excellent and 3 patients were good. All donor sites had primary healing with the motion of donor hips unaffected.Conclusion:Masquelet technique combined with free iliac inguinal flap is an effective, safe and feasible surgical procedure in reconstruction of infectious bone and soft tissue defect after metacarpal fracture surgery.

First, the donor site of the fibular hallux flap was sutured to reduce the size of wound. The width of the remaining wound was 0.4 to 1.6 cm, and the area of the remaining wound was 0.5 cm×0.8 cm-1.6 cm×1.8 cm. Then the remaining wound was repaired with the transverse V-Y advancement flap of the ipsilateral great toe. The distance for transfer of transverse advancement V-Y flap was 0.2-0.8 cm, and the area of the transverse V-Y advancement flap was 1.0 cm×1.4 cm-1.8 cm×2.4 cm. The end of postoperative follow-up was scheduled in July 2021. The follow-up items included: survival of the transverse V-Y advancement flap, wound infection, appearance, shape, texture and sensation of the V-Y advancement flap, pain on the V-Y advancement flap and the great toe, cold tolerance and the scar condition at the donor site of the ipsilateral fibular hallux flap and the V-Y advancement flap, the appearance, sensation and flexion and extension of the great toe at the donor site, other discomforts in the donor site of great toe, walking and other functions affected by the discomforts.Results:The postoperative follow-up lasted from 12 to 18(average of 14) months. All the V-Y advancement flaps survived without infection at the donor sites of the great toe, and donor sites healed primarily. The appearance, shape and texture of the advancement V-Y flap were close to the skin of the same area of the contralateral great toe. The TPD of the V-Y advancement flap and the ipsilateral great toe ranged from 4 to 7 mm. The average score of the Visual analog scale(VAS) was 0.3 and 0.6 respectively in the evaluation of cold tolerance of the advancement V-Y flap and the ipsilateral great toe. The average score of the Vancouver scar scale(VSS) was 0.2 and 1.2 respectively in the scar evaluation of the V-Y advancement flap and the ipsilateral great toe. There was no visual difference between the appearance of the great toe at the donor site and the contralateral toe. There was no pain and other discomfort on the V-Y advancement flap and the ipsilateral great toe. The functions of the donor foot were not affected in walking, running, jumping and tiptoeing in all cases.Conclusion:It is a simple, safe and effective method to repair the donor site of the small-area ipsilateral fibular hallux flap by the transverse V-Y advancement flap of the great toe. It only causes a small wound but the appearance and function of the ipsilateral great toe can be repaired with a transverse V-Y advancement flap of the great toe.
