Objective To observe any therapeutic effect of proprioception training and intra-articular injection of sodium hyaluronate on knee osteoarthritis (KOA) in the elderly.Methods Forty-five patients with KOA were randomly divided into a treatment group (23 cases) and a control group (22 cases).The arthritic knees of both groups were treated with sodium hyaluronate injections,but the patients in the treatment group also received proprioception training.Before treatment,and after 5 weeks and 3 months of treatment,knee function was assessed against Lysholm's assessment standard.Results There was no significant difference in the average Lysholm scores of the two groups before treatment.After 5 weeks and 3 months the patients in each group scored significantly higher than before treatment.After 3 months the average score of the treatment group was significantly higher than that of the control group.Conclusion Proprioception training and sodium hyaluronate injections together constitute a useful method to treat KOA in elderly patients.

Objective:To evaluate the clinical effect of fibula flap in the repair of large segment of composite tissue defect in upper limb.Methods:From April, 2015 to June, 2019, 7 patients with large composite tissue defects in upper limbs were treated. All of them with various skin, vessel, nerve, tendon and other tissue defects. Repairing was well planned before surgery according to the type, location and size of defect. While in repairing of the bone and skin defect, fibula flap was taken from the shank and to repair the defects of nerve, tendon and vessels in upper limb. Regular followed-ups were made after surgery.Results:The 7 fibula flaps all survived. Postoperative follow-up ranged between 8 to 36 (averaged of 15) months. All the reconstructed limbs were in satisfactory appearance and function recovery. All the patients were able to manage their daily activities and live independently. The shape and function of donor sites were good. According to the Enneking system, the outcomes were graded as excellent in 4 cases and good in 3, with the average score was 25.9 points.Conclusion:Free grafting of vascularised fibula flap is especially feasible to be used in the repair of large bone tissue defect of upper limb. It repairs the defects of skin, vessel, nerve and tendon with the flap from a single donor site.

Objective To observe the therapeutic effect of surface functional electrical stimulation combined with electroacupuncture on neurogenic bladder after the spinal cord injury.Methods Forty cases of neurogenic bladder after the spinal cord injury were randomly divided into a control group (n =20) and a combination group (n =20).The combination group was treated with surface functional electrical stimulation combined with electroacupuncture on the basis of internal urethral catheterization,while the control group was treated with surface functional electrical stimulation on the basis of internal urethral catheterization.The bladder urination was tested using urodynamic study before and after two months of treatment.Results There was no significant difference between the 2 groups in the average maximum bladder capacity,detrusor pressure at filling time,maximal urethral closure pressure,maximum urine flow rate and residual urine volume before the treatment.After the treatment,however,the average maximum bladder capacity,maximal urethral closure pressure and maximum urine flow rate in the combination group were significantly higher than those of the control group,while the average detrusor pressure at filling time and the residual urine volume of the combination group were significantly lower than the control group.Conclusion Surface functional electrical stimulation combined with electroacupuncture could remarkably improve bladder function of patients with the neurogenic bladder after the spinal cord injury.

Objective To identify the risk factors for deep vein thrombosis(DVT) in the lower extremities during hospitalization for acute spinal cord injury(SCI).Methods Retrospective data analyses were performed for 49 SCI patients admitted within a week after they were diagnosed.The patients were divided into a DVT-free(n =40) group and a DVT group(n =9) according to their lower limbs' color Doppler ultrasound results.And the subjects' gender,age,chronic diseases (diabetes,hypertension and hyperlipidemia,etc.),complications (pulmonary infection,urinary tract infections and pressure sores,etc.),the history of cancer,smoking history and lower extremity fractures were recorded.Intermittent pneumatic compression treatment,the early rehabilitation intervention,antithrombotic therapy,history of venous catheterization,operative intervention,blood transfusion history,muscle strength of lower extremity and time from onset to being transfered to rehabilitation department were also recorded Single factor analysis,was conducted,followed by Binary logistic regression to pick out the risk factors for DVT.Results The result of the binary logistic regression analysis showed that gender (OR 6.87 ; 95％ CI 1.09-43.22 ;P ＜ 0.05) and intermittent pneumatic compression treatment (OR 12.47 ; 95％ CI 1.09-142.36 ; P ＜ 0.05) were significant predictors of DVT.Conclusion Gender and intermittent pneumatic compression treatment are related with DVT risk for patients with acute SCI.

Objective To observe the effect of injecting botulinum toxin type A on muscle tension,disability level and ability in the activities of daily living in patients with post-stroke dystonia.Methods Thirty-two patients with post-stroke dystonia were divided into an observation group (n =16) and a control group (n =15).The patients in the observation group were injected with 200-600 U of botulinum toxin type A in the relevant muscles,while the patients in the control group were given 12 mg diphenhydrazole hydrochloride tablets orally.Before and 2,6 and 12 weeks after the treatment,spasticity,disability and daily living ability were evaluated in both groups using the modified Ashworth scale (MAS),a disability assessment scale (DAS) and the modified Barthel index (MBI).Results After the treatment,the average MAS,DAS and MBI scores of both groups were significantly better than before the treatment.And the average MAS,DAS and MBI scores of the observation group were significantly better than those of the control group.Conclusion Botulinum toxin A injection can significantly improve dystonia and relieve disability among stroke survivors.

Objective To investigate the displacement characteristics of intraoperative and postoperative positions of electrodes on CT imaging for bilateral subthalamic nucleus-deep brain stimulation (STN-DBS) in Parkinson's disease (PD).Methods A retrospective analysis on preoperative MR imaging,intraoperative and postoperative CT images of 35 patients with PD treated with STN-DBS in our hospital from January 2014 to June 2018 was performed.A three-dimensional coordinate system was established based on preoperative MR imaging.MR imaging/CT fusion technique was used to fuse intraoperative and postoperative CT images with preoperative MR imaging to locate intraoperative and postoperative electrode positions.The displacement characteristics of intraoperative and postoperative electrodes were analyzed.Results The spatial distance between intraoperative and postoperative positions of bilateral electrodes was about 1 mm,and the depth displacement was minimal.The postoperative position of the first side electrode on lateral axis was shifted outwardly from intraopemtive position,and the second side electrode was shifted internally with a small degree;on anterior-posterior axis,the first side electrode obviously shifted backward,and the second side electrode slightly shifted backward.For bilateral electrodes,corresponding coordinate deviation of three axis between intraoperative electrode-preoperative target and postoperative electrode-preoperative target,showed a significant positive linear correlation,therefore,leading out the coordinate deviation regression function model.Conclusions The displacement of electrodes between intraoperative and postoperative positions has obvious rules after STN-DBS in PD,which can guide the adjustment of intraoperative electrode position and predict the postoperative position of electrode.

Patients with severe trauma require an extremely timely treatment and transfusion plays an irreplaceable role in the emergency treatment of such patients. An increasing number of evidence-based medicinal evidences and clinical practices suggest that patients with severe traumatic bleeding benefit from early transfusion of low-titer group O whole blood or hemostatic resuscitation with red blood cells, plasma and platelet of a balanced ratio. However, the current domestic mode of blood supply cannot fully meet the requirements of timely and effective blood transfusion for emergency treatment of patients with severe trauma in clinical practice. In order to solve the key problems in blood supply and blood transfusion strategies for emergency treatment of severe trauma, Branch of Clinical Transfusion Medicine of Chinese Medical Association, Group for Trauma Emergency Care and Multiple Injuries of Trauma Branch of Chinese Medical Association, Young Scholar Group of Disaster Medicine Branch of Chinese Medical Association organized domestic experts of blood transfusion medicine and trauma treatment to jointly formulate Chinese expert consensus on blood support mode and blood transfusion strategies for emergency treatment of severe trauma patients ( version 2024). Based on the evidence-based medical evidence and Delphi method of expert consultation and voting, 10 recommendations were put forward from two aspects of blood support mode and transfusion strategies, aiming to provide a reference for transfusion resuscitation in the emergency treatment of severe trauma and further improve the success rate of treatment of patients with severe trauma.
