Objective To provide reference for the subsequent clinical application of WBV,based on the impacts of whole body vibration(WBV)with different frequencies on gross motor function and walking function in children with dyskinetic cerebral palsy.Methods 60 children aged 6～12 with dyskinetic cerebral palsy,who had been treated at the department of rehabilitation medicine in the Affiliated Southwest Medical University from October 2021 to November 2022,were selected.They were randomly divided into a control group(n = 20),(25±5)Hz group(n = 20),and(35±5)Hz group(n = 20).All the three groups received conventional rehabilitation,while the(25±5)Hz group received additional WBV with(25±5)Hz and the(35±5)Hz group received WBV with(35±5)Hz.They were treated for eight weeks.The scores on D and E domains of GMFM-88,TUGT,the score on Berg Balance Scale,and footprint analysis were used for assessment of the efficacy after treatment.Results As compared with the baselines,the scores were improved in the three groups after treatment(P＜0.001).BBS(F = 12.502),TUGT(F = 8.211),scores on D and E domains of GMFM-88(F = 12.802 and 8.505),stride length(F = 12.279),1MWT distance(F = 12.619),and step width(F = 13.582)were better in the(35±5)Hz group than in the(25±5)Hz group and the control group(P＜0.05 and P＜0.01);and the efficacy was better in the(25±5)Hz group than in the control group,the difference was statistically significant(P＜0.05 and P＜0.01).Conclusion WBV can improve trunk control,lower limb gross motor function,and walking function in children with involuntary motor type cerebral palsy.(35±5)Hz is better than(25±5)Hz for the efficacy of WBV.

Objective Comprehensive mortality risk analyses and therapeutic assessment in real-world practice are beneficial to guide individual treatment in patients with Carbapenem-resistant Klebsiella pneumoniae bloodstream infections(CRKP-BSI).Methods Retrospective analysis of the clinical characteristics of 81 CRKP-BSI patients in our intensive care unit from July 2016 to June 2020,to indentify the risk factors of death and treatment effects of different antibiotic regimens.Results In 81 CRKP-BSI cases,the majority source were from abdominal and respiratory,accounting for 56.79%(46 cases)and 22.22%(18 cases),respectively.The 28-day mortality and hospitalization mortality of CRKP-BSI were 54.32%(44 cases)and 65.43%(53 cases).Multivariate regression analysis suggested that biliary tract disease before admission(P=0.026)and increased SOFA score at the onset of BSI(P=0.006)were independent risk factors for 28-day mortality.There was no statistically significant difference in 28-day mortality between the groups of antibiotic treatment based on tigecycline(44 cases)and polymyxin B(26 cases)[56.82%(25/44)vs.57.69%(15/26),P=0.943].Patients were evaluated based on their age(≤65 years vs.>65 years),gender,body mass index(≤25 kg/m2 vs.>25 kg/m2),and APACHEⅡ score(≤20 vs.>20),the use of renal replacement therapy and mechanical ventilation,there was no difference in the mortality among each subgroup.Conclusions Biliary tract disease before admission and SOFA score were independent risk factors for 28-day mortality.There was no significant difference outcomes between tigecycline-and polymyxin B-based therapy.
