OBJECTIVE To screen potential adverse drug event （ADE） signals for the treatment of multiple sclerosis （MS） with ofatumumab， and to provide reference for the safe use of drugs in clinical practice. METHODS Using “ofatumumab” and the trade name “Kesimpta” as the search keywords， adverse event （AE） reports related to ofatumumab included in FDA Adverse Event Reporting System database from January 2009 to December 2023 were screened， and their reason contained the “multiple sclerosis”； ADE signal mining and analysis were conducted by reporting odds ratio method and proportional reporting ratio method. RESULTS A total of 21 759 eligible AE reports were selected， involving 62 449 AE cases； 27 system organ classes included general diseases and various reactions at the site of administration （15 021 cases）， neurological diseases （9 668 cases）， infectious and invasive diseases （5 967 cases）， injury， poisoning and surgical complications （4 952 cases）， musculoskeletal and connective tissue disorders （4 647 cases）. A total of 21 759 AE reports correspond to 606 ADE signals， including 234 ADE positive signals. A total of 107 ADE positive signals were not included in drug instruction of ofatumumab， including flu-like diseases， nasopharyngitis， cough， urinary tract infection， sore throat， insomnia， runny nose， anemia， hair loss， atrial fibrillation， and thrombocytopenia， etc. CONCLUSIONS In the process of using ofatumumab for MS， sufficient attention should be paid to ADE included in drug instructions. The ADE with strong signal strength screened in this study should also be paid special attention to， such as flu-like diseases， hemocytopenia， temperature intolerance， optic neuritis， and moyamoya disease. The increased risk of infection， cardiovascular disease， and potential damage to the respiratory and spiritual systems caused by ofatumumab can not be ignored.

BACKGROUND:With the increase of patients with cubital tunnel syndrome,ulnar groove plasty does not affect the normal anatomical structure and distribution of the ulnar nerve,which is one of the main surgical procedures for the treatment of cubital tunnel syndrome.3D printing combined with ulnar groove plasty can more accurately position the expansion depth and width of the ulnar groove to avoid some surgical complications. OBJECTIVE:To investigate the effect of 3D printing technology combined with ulnar groove plasty on nerve electrophysiology and prognosis in patients with cubital tunnel syndrome. METHODS:A total of 70 patients with moderate and severe cubital tunnel syndrome who were treated in Cangzhou Integrated Traditional Chinese and Western Medicine Hospital from March 2020 to March 2022 were selected as the study subjects.They were divided into two groups,with 35 cases in each group.The control group underwent traditional ulnar groove plasty.The observation group underwent 3D printing technology combined with ulnar groove plasty.The patients were followed up for 3 months.The clinical efficacy,latency,amplitude of compound muscle action potential of abductor pollicis brevis of the affected limb and ulnar nerve motor conduction velocity,grip strength on the affected side,pinch strength of the middle and thumb fingers,S-W monofilament of the little finger,two-point discrimination of the little finger,and Disabilities of the Arm,Shoulder and Hand Questionnaire score were compared between the two groups. RESULTS AND CONCLUSION:(1)Compared with the control group(74%),the excellent and good rate was significantly higher in the observation group(91%)(P<0.05).(2)Compared with pre-treatment,the latency of compound muscle action potential of abductor pollicis brevis of affected limb was significantly shorter and the wave amplitude and ulnar nerve motor conduction velocity were significantly higher in the two groups after treatment.The latency was significantly shorter and the wave amplitude and ulnar nerve motor conduction velocity were significantly higher in the observation group than those in the control group(P<0.05).(3)Compared with pre-treatment,the grip strength,middle finger and thumb pinch strength of the affected side,S-W monofilament of the little finger and two-point discrimination of the little finger were significantly decreased in the two groups after treatment.The grip strength,middle finger and thumb pinch strength on the affected side were greater,S-W monofilament of the little finger and two-point discrimination of the little finger were significantly smaller in the observation group than those in the control group(P<0.05).(4)Compared with pre-treatment,the Disabilities of the Arm,Shoulder and Hand Questionnaire scores of the two groups were significantly reduced after treatment,and the Disabilities of the Arm,Shoulder and Hand Questionnaire scores of the observation group were significantly lower than those of the control group(P<0.05).(5)It is concluded that 3D printing technology combined with ulnar groove plasty in the treatment of cubital tunnel syndrome can effectively improve its clinical efficacy,promote the neurophysiological recovery of patients,and enhance the function of fingers and upper limbs,which has high clinical application value.

Objective: Understanding mental health status of students with learning disabilities in Beijing to provide a basis for mental health promotion of students with learning disabilities. Methods: By means of random cluster sampling, 5 787 enrolled students in grade one and grade two of 11 public junior middle schools in Beijing were selected as the survey subjects. A self designed questionnaire was used to investigate the students’ learning disabilities and mental health status through anonymous self filling. Results: About 11.6% students self reported learning disabilities. The proportions of students with learning difficulty in mathematical reasoning and calculation were higher, 44.1% and 40.7% respectively. The reported rate of mental health problems was 38.3%. The top four of the 10 symptoms were obsessive compulsive symptoms, learning pressure, emotional instability and anxiety(2.19±0.77)(2.17±0.99)(2.09±0.90)(2.07±1.08). Compared with students without learning disabilities, students with self reported learning disabilities had poorer mental health status(OR=1.47), and learning disabilities were related to most factors of mental health. Different types of learning disabilities were associated with different mental health factors. Conclusion Mental health problems of students with learning disabilities are higher than that of students without learning disabilities. It is necessary to strengthen the mental health support for students with learning disabilities and improve their mental health.

Objective:To investigate the method and clinical effect of ultrasound-guided thrombin injection in the treatment of femoral pseudoaneurysm.Methods:From January 2017 to December 2019, 71 patients in Gongren Hospital with femoral pseudoaneurysm were treated by ultrasound-guided thrombin injection. There were 55 cases of fistula type and 16 cases of fissure type. The maximum diameter of the cavity and the neck of pseudoaneurysm were measured and recorded. Two groups of patients were injected thrombin under ultrasound guidance (according to the shape of the pseudoaneurysm neck, different injection methods were used). The treatments for the first time and first recurrence of the two groups were treated with the corresponding conventional injection method. For the second fracture type of the second recurrence of the patients, the method of cross injection and gradual advance to the pseudoaneurysm neck was used for the third time, and the compression time was extended after the blood flow in the cavity disappeared. Ultrasound was performed at 24 hours and 1 week after operation to observe the blood flow and thrombosis.Results:In 55 patients with pseudoaneurysm of fistula type, 54 patients were treated successfully after once injected, pseudoaneurysm recurred in 1 patient relapsed by ultrasound 24 hours after operation, and the second injection was successful. In 16 patients with pseudoaneurysm of fissure type, 10 patients were successfully treated after once injection, 6 patients recurred 24 hours after operation, 4 patients were successfully treated after the second injection, and 2 patients after the third injection. There was no correlation between the recurrence of fistula pseudoaneurysm and the diameter of the pseudoaneurysm neck( r s=0.103, P=0.455), while the recurrence of fissure pseudoaneurysm was closely related to the diameter of the pseudoaneurysm neck( r s=0.870, P<0.001). Finally, all the patients achieved satisfactory curative effect, and the cure rate was 100%. Conclusions:Ultrasound-guided thrombin injection in the treatment of femoral pseudoaneurysm has a significant clinical effect. However it is necessary to determine the shape of the pseudoaneurysm neck and measure the diameter of the pseudoaneurysm neck before operation, so as to adopt a reasonable and effective injection method, to improve the success rate of the first treatment and reduce the recurrence.

Objective To systematically review the short-term and long-term efficacy of eversion carotid endarterectomy (eCEA) and patch carotid endarterectomy (pCEA) for the treatment of carotid artery stenosis.Methods The published literature on eCEA and pCEA control studies in medline,PubMed,Ovid,CNKI and CBM (1970.5-2016.10) databases were retrieved by computers.Two reviewers selected literature and extracted data independently according to the inclusion and exclusion criteria.Cochrane Collaboration Network Special Software Rev Man 5.2 was used to analyze the meta-analysis of short-term and long-term outcome measures.Results A total of 1 137 articles were retrieved.Ten studies were included and analyzed (3 of them were randomized controlled trial).A total of 3 213 patients were enrolled,including surgical intervention 3 299 case/time (1 512 in the eCEA group and 1 787 in the pCEA group).The results of meta-analysis showed that:(1) the mean operative time in the pCEA group was shorter 22±8 min than that in the pCEA group.The intraoperative utilization ratio of shunt tube,eCEA was significantly lower than pCEA,they were 12.6 %(53/421) and 50.2% (357/711) respectively (OR,0.11,95%CI 0.08-0.15,P<0.01).The postoperative incidence of stroke within 30 d (OR,0.42,95%CI 0.23-0.76,P=0.004) and the incidence of stroke after 30 d in eCEA were lower than those in pCEA (OR,0.26,95%CI 0.09-0.78,P=0.02).There was significant difference.(2) eCEA reduced the incidence of restenosis at day 30 after procedure (OR,0.57,95%CI 0.38-0.86,P=0.008).Conclusion Compared with pCEA,eCEA has the advantages of reducing the operation time and lowering the utilization rate of shunt tube.At the same time,eCEA can reduce the occurrence of stroke within 30 d and 30 d after procedure,and significantly reduce the incidence of restenosis.

Objective To evaluate the effect of surface electromyography (sEMG) applied bilaterally to the limbs in the rehabilitation of motor dysfunction among stroke survivors.Methods Sixty stroke survivors were randomized into a bilateral group (n =30) and a control group (n =30).Both groups received routine rehabilitation for 4 weeks,but the bilateral group accepted additional limb rehabilitation training for the uninjured side.Before and after the intervention,motor function was assessed using sEMG during maximal voluntary contraction of the deltoid,biceps,triceps,rectus femoris,biceps femoris and tibialis anterior muscles.Integrated EMG (iEMG) and root mean square (RMS) values were computed.Results Before the training there was no significant difference in any of the measurements between the two groups.After the training both groups had significantly improved the average strength of their maximum contractions and their average iEMG and RMS values.The bilateral group,though,demonstrated significantly better results than the control group.Conclusion Bilateral limb rehabilitation training is superior to the conventional unilateral procedure in improving the motor function of stroke survivors.

Objective To investigate the effects of platelet-rich fibrin (PRF) on BMP-6 expression during mandibular distraction osteogenesis. Methods Twenty-five mature rabbits were randomly divided into five groups. Mandibular osteoto?mies were performed corticectomy in bilateral mandibles of rabbits. PRF was implanted in the one side of mandibles, which was used as experimental group. Another side of madibular was used as control group. Rabbits were sacrificed and the dis?tracted calluses were harvested and processed for HE and BMP-6 immunohistochemistry staining at 1, 3, 7, 14 and 28 days after the end of distraction, respectively. The expressions of BMP-6 in the distracted calluses were analyzed by cell digital imaging software. Results The regenerated bone was found in the distraction gap after mandibular lengthening. Expres?sions of BMP-6 were co-localized in cytoplasm of osteoblasts and newly embedded osteocytes. Compared with control group, the positive cell rate and positive area percentage of BMP-6 were significantly higher on the 1st, 3th and 7th day after the distraction in experimental group (P<0.05). There were no significant differences in positive cell rate and positive area per?centage of BMP-6 at 14-day and 28-day after the distraction between experimental group and control group. Conclusion PRF can accelerate bone formation of mandibular distraction osteogenesis in rabbits. BMP-6 may play important role at the early stage of mandibular distraction.

Objective To discuss the application of Occupational Functioning Model (OFM) in occupational therapy teaching. Methods The students in grade 2009 and 2010 for their course of Occupational Therapy Clinical Application were included. The former were taught in routine way, and the latter were taught with OFM. They were investigated with questionnaires of satisfaction of course and teaching. Results There were 94.1% of the students felt beneficial in the clinical thinking, 86.3% in the comprehensive quality. There was more in the grade 2010 than 2009 of students reported to be benefited in such as guidance of the occupation mode for the clinical practice, independent thinking, clinical thinking, and the capability of evaluation and plan of systemic rehabilitation (P<0.05). Conclusion OFM may help students to understand occupational therapy deeply, develop the clinical thinking, and improve the comprehensive quality.

Objective To discuss the impact of the pattern of student-autonomous laboratories opening on the experimental teaching of rehabilitation specialty. Methods Laboratories were opened to sophomore students of rehabilitation specialty. Planned opening pattern is employed on students of 2009 class and autonomous opening pattern is used on students of 2010 class. At the end of each term, results of these opening patterns are compared. Results The total opening hours of planned opening pattern were 89 with 755 person-times involved. The accumulated opening hours of autonomous opening pattern were 323 with 2677 person-times involved. Students of the autonomous opening pattern class achieved better academic results than students of planned opening pattern (P<0.05) in 7 major courses. Opening laboratories to students contributed to the improvement of rehabilitation skills, better understanding of the curricular knowledge, the enhancement of problem-analyzing and problem solving abilities, the stimulation of interest in major study and also the fostering of teamwork spirit. And the autonomous opening pattern achieved more desirable results (P<0.05). Conclusion The student-autonomous lab opening pattern contributes more to the improvement of students' practical skills, innovative spirit as well as comprehensive clinical rehabilitation abilities.

Objective To study the effects of self-management of knee osteoarthritis (KOA) on the function and quality of life in old patients. Methods From October 2011 to April 2012, 100 patients with KOA from 2 communities in Tangshan, Hebei were recruited, and were as control group and intervention group based on the community. The intervention group learned a KOA self-management course, which consisted of 6 classes of 1.5 to 2 hours, once a week, taught by health professionals. The control group read the KOA self-management handbook only. They were measured with the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) and Arthritis Impact Measurement Scale 2nd version- Short Form (AIMS2- SF) before and 6 months after intervention. Results The score of WOMAC and AIMS2-SF improved more in the intervention group than in the control group (P<0.05). Conclusion The KOA self-management program is effective on function and quality of life in old patients with KOA in community.
