Objective To investigate the clinical effect on incomplete spinal injury by ganglioside intravenous injection combined with intrathecal injection.Methods From January 2011 to January 2015, seventy-nine cases with irreducible articular process interlocking of cervical spine fracture with dislocation of cervical spinal cord injury,underwent one stage anterior and posterior surgical treatment,postoperative routine use of antibiotics to prevent infection,and the hormone,dehydration to promote bone cell growth and neurotrophic drugs treatment.The patients were randomly divided into the intravenous injection group(42 cases),given intravenous injection of monalsialic acid four hexose ganglioside sodium(GM-1)40 mg/d,mecobalamin tablets 0.5 mg/time,3 times/d,30 d oral;the combined intrathecal injection group(37 cases)was given GM-1 40 mg/d,intravenous injection at 15 d after intrathecal injection,1 time a week 40 mg,with a total of 4 weeks.The degree of spinal cord injury was evaluated according to Frankel classification; cervical function was evaluated according to JOA score; bone graft fusion,stability of cervical spine and degree of spinal cord injury were evaluated by imaging.Results The operation time in the intravenous injection group and the combined intrathecal injection group were(4.15 ± 0.65)h and(4.10 ± 0.85)h,and the intraoperative blood loss was(850.50±35.10)ml and(858.60±25.20)ml,respectively,and there were no significant differences between the two groups(t=1.375,1.452,P>0.05).The total dose of GM-1 in the combined intrathecal injection group was(785.20 ± 3.28)mg,significantly higher than that in the intravenous injection group((610.55 ± 5.28) mg),the difference was statistically significant(t=12.542,P<0.05);79 patients were followed up for 12-24 months,with an average of(15.2 ± 1.3)months.The improvement rate of nerve function of the combined intrathecal injection group was(64.35±4.33)%,significantly higher than that in the intravenous injection group (55.50±5.44)%,the difference was statistically significant(t=8.813,P<0.05);the postoperative JOA scores of the intravenous injection group((13.55 ± 1.75)points)and combined intrathecal injection group((12.85 ±1.97)points)were significantly higher than those before the surgery((7.25± 0.83)points,(7.19± 0.93) points),the differences were statistically significant(P<0.05).There was no significant difference in the JOA scores between the two groups before and after the operation(P>0.05).At the last follow-up,X-ray showed bone fusion at the bone graft site,and the internal fixation was good and firm.MR showed that the degeneration signal area of the cervical spinal cord decreased in varying degrees,and edema and inflammatory reaction disappeared.Conclusion Postoperative treatment of ganglioside intravenous injection combined with intrathecal injection is safe and feasible in the treatment of incomplete cervical spinal cord injury caused by cervical fracture dislocation with irreducible articular process interlocking.

The effects of intramuscular or intracerebroventricular injection of penta-gastrin(PG) on the action potential amplitude (APA) of the myocardial cells and the heart rate(HR) were studied. The results were as follows:1 ) Injection of 10?g/10?l of PG into one of the lateral ventricles of the ratfailed to produce any effect on APA or HR. When the dosage of PG was doubled(20?g/10?l), then HR could be slowed down significantly (P

Objective: To explore the longitudinal association of the levels of plasma irisin among children with changes in obesity related parameters and newly onset obesity, and to explore whether physical activity (PA) and sedentary behavior(SB) have regulatory effects, to provide a scientific basis for the prevention and control of childhood obesity work. Methods: Cluster random sampling method was used to select 521 children from five schools in Guangzhou in 2017 at baseline and were followed up in 2019. A based on baseline PA and SB, children who meet the following criterion were selected:moderate vigorous intensity PA≥60 min/d or <150 min/week; and gender , age specific SB≥ P 75 or SB < P 25 . Plasma irisin concentration was measured in all the selected children. Multiple linear regression and Logistic regression were conducted to analyze the association. Results: The two year cumulative incidence of obesity, overweight and obesity, and central obesity was 2.82%, 6.57%, and 6.81%, respectively. There was no statistically significant association between plasma irisin levels and changes in obesity related parameters, newly onset overweight obesity or central obesity among children ( P >0.05). After stratified by PA, the irisin concentration in the low PA group was positively associated with weight change ( B=0.229, P =0.03). After stratified by SB, the irisin concentration in the low SB group was positively associated with the height change ( B=0.210, P <0.05). In addition, PA level and SB level both had a moderating effect on the association between plasma irisin levels and the weight change ( P PA=0.01, P SB =0.05). Conclusion PA and SB show moderating effect on plasma irisin concentration and weight gain. No association of irisin concentration with newly onset overweight or obesity among children has been found.
