ABSTRACT
Objective To investigate the curative effect of low temperature plasma radiofrequency ablation and ozone injection in the treatment of lumbar disc herniation (LDH) and its effect on the quality of life of patients.Methods 240 patients with LDH who were treated in Xining First People's Hospital from December 2015 to February 2017 were enrolled in the study.The patients were divided into low temperature plasma group (low temperature plasma radiofrequency ablation therapy) and ozone injection group (ozone injection therapy) by random number table method,with 120 cases in each group.The operative indexes,complications,and visual analogue scale (VAS) score at different time points,numbness and muscle strength indexes and WHO quality of life scale (WHOQOL-BREF) score were compared between the two groups.The clinical efficacy was compared between patients with different image credit type in two groups.Results The operation time,hospitalization time and the cost of treatment in the ozone injection group were less than that of the low temperature plasma group (P ＜ 0.05).There was no significant difference in VAS score and numbness score between the two groups at different time points (P ＞ 0.05).The abdominal time and the supine crouch time in the low temperature plasma group in 3 months after operation were longer than those in the ozone injection group (P ＜ 0.05).The excellent rate of the lateral type in low temperature plasma group in 3 months and 6 months after operation was higher than that in the ozone injection group (P ＜0.05).The physiological field score,psychological field score and total score in WHOQOL-BREF of low temperature plasma group in 1 month,3 months and 6 months after operation were significantly higher than those of ozone injection group (P ＜ 0.05).There was no significant difference in the incidence of complications between the two groups (P ＞ 0.05).Conclusions Low temperature plasma radiofrequency ablation has better effect in the treatment of lateral LDH,and it can improve lumbar and dorsal muscle strength and lumbar abdominal muscle strength more obviously,improve the quality of life of the patients,but the operation time and hospitalization time are longer,and the cost of treatment is higher.
ABSTRACT
This paper reported a method of determination of phosphorus in human hair by Spectrophotometry of phosphomolybdenum Blue.Samples were decomposed by means of dry ashing.Vitamin C was used as a reducing agent.The conditions of ashing and colouration of phosphomolybdehum Blue,the measurement wavelength and the confidence of this meth od were also studied.
