Meta-analysis of clinical efficacy of ankle arthrodesis and total ankle arthroplasty in the treatment of end-stage ankle arthritis / 中国骨伤

OBJECTIVE@#To systematically review the clinical efficacy of total ankle arthroplasty (TAA) and ankle arthrodesis (AA) in the treatment of end-stage ankle arthritis.@*METHODS@#The PubMed, EMBASE and Cochrane Library databases were searched for articles published in the treatment of end-stage ankle arthritis with AA or TAA from the establishment of the database to June 2021. Bias risk tool was used to evaluate the quality of the literature. The American Orthopaedic Foot and Ankle Society Ankle-Hindfoot Scale(AOFAS), visual analog scale (VAS), ankle osteoarthritis scale(AOS), gait analysis (pace, frequency, stride), range of motion (ROM), satisfaction, complications and reoperation rate were analyzed by meta-analysis between AA and TAA groups by RevMan 5.3 software.@*RESULTS@#A total of 12 articles were included, including 1 050 patients in the AA group and 3 760 patients in the TAA group, totaling 4 810 patients. Meta-analysis showed that the total score of AOFAS[MD=-3.12, 95%CI(-9.02, 2.96), P=0.31], pain score [MD=1.60, 95%CI(-1.35, 4.54), P=0.29], alignmentl score[MD=-0.04, 95%CI(-0.52, 0.44), P=0.88], VAS[MD=0.10, 95%CI(-0.49, 0.68), P=0.74], and AOS total score [MD=-4.01, 95%CI(-8.28, 0.25), P=0.06], the difference was not statistically significant (P>0.05). The score of AOFAS functional in TAA group was significantly higher than that in TAA group[MD=44.22, 95%CI(-8.01, -0.43), P=0.03]. There was no significant difference in gait analysis between the two groups (P>0.05). Postoperative ROM [MD=-4.93, 95%CI(-6.35, -3.52), P<0.000 01] and change in ROM from preoperative to follow-up[MD=-5.74, 95%CI(-8.88, -2.61), P=0.0003] between two groups, the difference was statistically significant. There was no significant difference in satisfaction between the two groups [OR=1.011, 95%CI(0.46, 2.23), P=0.98]. Complications [OR=1.61, 95%CI(1.26, 2.06), P=0.0002] and non-revision reoperation [OR=1.61, 95%CI(1.17, 2.21), P=0.003] were significantly lower in the TAA group than in the AA group. There was no significant difference in the rate of revision and reoperation(P>0.05) between the two groups [OR=1.02, 95%CI(0.37, 2.78), P=0.97].@*CONCLUSION@#The clinical efficacy of AA is similar to that of TAA, but the non revision reoperation rate and main surgical complications of TAA are significantly reduced. Therefore, further high-quality methodological research and long-term follow-up are needed to confirm this conclusion.

Design of medical UV lamp control system based on development board / 医疗卫生装备

Objective To design a medical ultraviolet lamp control system based on a development board to achieve remote control and usage time recording of medical UV lamps.Methods The system was composed of a WeMos D1 mini development board,a 1-way relay module,an OLED display,a RCWL-0516 microwave radar sensor and an ACS712 current monitoring module,which had its control program written by integrated development environment(Arduino IDE).Results Tests proved the system developed functioned well in timed disinfection,manual disinfection and system timing;the ACS712 current monitoring module could detect the lamp failure and current failure;the system could immediately turn off the ultraviolet lamp when persons entered the space to be disinfected;the medical staff could be prompted to replace the lamp when it's about to run out of expiration date.Conclusion The medical UV lamp control system developed gains advantages in easy operation and low cost,and realizes remote control and usage time recording of medical UV lamps.

Effect of electronic moxibustion on activity of parapharyngeal wall in patients with achalasia of cricopharyngeus muscle after stroke based on musculoskeletal ultrasound / 中国针灸

OBJECTIVE@#To observe the clinical effect of electronic moxibustion on dysphagia in patients with achalasia of cricopharyngeus muscle after stroke.@*METHODS@#Sixty patients with dysphagia of achalasia of cricopharyngeus muscle were randomly divided into an observation group and a control group, 30 cases in each group. One patient in the observation group and 2 cases in the control group dropped off. The patients in the control group were treated with routine medical treatment, acupuncture treatment and swallowing rehabilitation training; the patients in the observation group were additionally treated with electronic moxibustion at Lianquan (CV 23), Tiantu (CV 22), Tianding (LI 17) and Futu (LI 18), 30 min each treatment. Both groups were treated 5 times a week for 4 weeks. The musculoskeletal ultrasound (MSUS) was applied to test the activity of parapharyngeal wall and the dysphagia score of Ichiro Fujishima was compared before and after 4-week treatment.@*RESULTS@#After treatment, the activity of the parapharyngeal wall and the dysphagia score of Ichiro Fujishima were increased in both groups (<0.01, <0.05). The changes of activity of parapharyngeal wall and dysphagia score of Ichiro Fujishima in the observation group were greater than the control group (<0.05, <0.01).@*CONCLUSION@#Electronic moxibustion can improve the impaired swallowing function and reconstruct the normal swallowing process.
