Objective To explore the effects of walking in water on surface electromyography (sEMG) of lower limbs and neural func-tion in spinal cord injury (SCI) patients. Methods From June, 2014 to May, 2016, 42 patients with incomplete thoracolumbar SCI were di-vided into control group (n=21) and experimental group (n=21) randomly. All the patients accepted routine rehabilitation, while the experi-mental group accepted extra walking in water. Average electromyography (AEMG) of quadriceps femoris and tibialis anterior muscles was measured, and the motor and sense function was assessed with American Spinal Injury Association (ASIA) Classification before and six weeks after treatment. Results The AEMG (t>5.763, P<0.01) and the scores of motor and sense (t>10.871, P<0.001) increased in both groups after treatment, and increased more in the experimental group than in the control group (t>4.036, P<0.01). Conclusion Walking in water could further improve lower limbs muscle strength and neural function in patients with incomplete thoracolumbar SCI.

Objective To analyze the value of serum ferritin(SF)in the early diagnosis of Mycoplasma pneumoniae pneumonia(MPP)based on decision curve analysis(DCA)and dose-response relationship.Meth-ods A total of 104 MPP patients in Taizhou People's Hospital from October 2016 to October 2021 were se-lected as the MPP group,and 90 healthy adults who underwent physical examination in Taizhou People's Hos-pital during the same period were selected as the healthy group.The clinical data of the two groups were com-pared.The influencing factors of MPP in patients were screened.The diagnostic value of SF for MPP was analyzed,the best cut-off value was sought,and the clinical predictive value of SF for MPP was evaluated.Results White blood cell count,C-reactive protein,tumor necrosis factor-α,lactate dehydrogenase,SF were independent risk factors for MPP,and 25-hydroxyvitamin D was its protective factor(P＜0.05).The dose-response relationship analysis showed that there was a nonlinear dose-response relationship between the continuous change of SF and MPP(P＜0.05).When SF＞127.68 ng/mL,the risk of MPP increased with the increase of SF level.DCA analysis showed that SF had important clinical value in the early prediction of MPP.Conclusion SF has a high value in the early diagnosis of MPP,and there is a nonlinear dose-response relationship between SF and MPP.When SF＞127.68 ng/mL,the risk of MPP increases with the increase of SF level.
