Objective To investigate the analgesia effect and the possible mechanism of intravenous administration with different concentrations of ozonized saline (OS) by observing changes in behavior,plasma tumor necrosis alpha (TNF-α),and interleukin-6 (IL-6) levels after rat plantar incision.Methods Fifty-four health adult male Sprague-Dawley rats were used in the investigation.Twenty four rats were randomly divided into four groups,6 in each group.The rats in group A1 were intravenously administered with 5ml/kg oxygen saline,10min before the incision.The rats in groups B1,C1,and D1 were intravenously administered with 20 μg/ml,30 μg/ml,and 40 μg/ml OS 5 ml/kg.An 1-cm incision was made in the right plantar surface from the heel to the toes according to the method described by Brennan under sevoflurane anesthesia.The 50％ paw withdrawal mechanical threshold (50％ PWMT) and cumulative pain score (CPS) at the times of 24 h before and 2,6,24,48 h after surgery were underwent.Thirty rats were randomly divided into five groups,6 in each group.Groups A2,B2,C2,and D2 processed as well as group 1.All groups except group E2 were made the model of incisional pain.2 ml blood was taken out of the right ventricular 2 h after the operation,then the levels of plasma TNF-α and IL-6 were detected by using enzyme linked immunosorbent assay (ELISA).Results There were no significant differences in the 50％PWMT between group A1 and group B1 at each time point after surgery (P ＞ 0.05).The 50％ PWMT in groups C1 and D1 were higher than those in group A1 at each time point after surgery (P ＜ 0.05).The CPS in groups B1,C1,and D1 were lower than those in group A1 after surgery (P ＜ 0.01).Compared to group E2,the levels of plasma TNF-α 2 h after the operation in group B2 and D2 were not statistically different (P ＞ 0.05).The levels of plasma TNF-α in groups C2 and A2 were higher than those in group E2 (P ＜ 0.05).The levels of plasma IL-6 2 h after the operation between group A2 and group E2 showed no difference (P ＞ 0.05).The levels of plasma IL-6 in groups B2,C2,and D2 were higher than those in group E2 (P ＜ 0.05).Concltsions Intravenous administration of ozonized saline can inhibit the incisional pain in rats.The analgesia effect of ozonized saline was dose-dependent.

Objective To investigate the effects of exogenous glial cell derived neurotrophic factor (GDNF)on colon glial cells in slow transit constipation (STC ) rats,and to explore the optimal concentration of GDNF in order to provide evidence for intestinal neurotrophic therapy in the treatment of STC.Methods A total of 132 SD rats were divided into STC group and control group,66 rats in each group.STC rats were established by feeding with rhubarb.Six rats were randomly selected from either groups to verify whether STC model was successfully established.And the left 120 rats of two groups were randomly divided into six subgroups:STC group one to group six and control group one to group six,ten rats in each group,which were untreated,injected through tail vein with saline,and 0.001 ,0.010, 0.050,0.100 μg/L GDNF 2 mL respectively for one week.The expression of Sox-8 at protein level of either group were detected by Western blotting.Independent sample t test was performed for statistical analysis.Results After treated with 0.001 μg/L GDNF (STC group three),there was no significant
difference in expression level of Sox-8 between STC group three and STC group one (13.38 ±0.70 vs 13.39±0.45 ,t = 0.042,P = 0.969 ).After treated with 0.010 μg/L GDNF (STC group four),the difference in expression level of Sox-8 between STC group four and STC group three was significant (21 .11 ±2.56 vs 13.38±0.70,t=5 .040,P <0.01).After treated with 0.050 μg/mL GDNF (STC group five),the expression level of Sox-8 was higher than that in STC group four (31.86±1.57 vs 21.11±2.56,t=-6.198,P <0.01 ).The Sox-8 expression of untreated,saline treated,0.001 and 0.050 μg/L GDNF treated STC rats (STC group one,two,three and five)were lower than those of the corresponding control groups (t= 3.394,12.103,10.302,- 6.120,all P < 0.05 ).Conclusion Exogenous GDNF could increase Sox-8 expression in colon tissue of STC rats,an increase in the number of colon glial cells could repair enteric nervous system,and 0.050 μg/L was the optimal concentration.

Subcortical ischemic vascular disease (SIVD) is considered to be the most important and common cause of vascular cognitive impairment (VCI). If patients with subcortical ischemic vascular cognitive impairment (SIVCI) and subcortical vascular cognitive impairment (sVCI) can be found early, it is possible that vascular dementia (VaD) can be identified before occurrence and even reverse the process. Recent studies have shown that resting-state functional magnetic resonance imaging (rsfMRI) may provide the objective basis for the diagnosis of SIVCI. This article reviews the application of rsfMRI in the diagnosis of SIVCI.

Cerebral palsy (CP) is the most common activity limitition of children, their movement and posture impairments persist throughout whole life.In recent years, CP has been significantly increasing with the improved survival rate of newborns.This may lead to a great burden and costs to both the family and the society.A variety of risk factors have been proposed to be associated with CP.However, recent abroad researches indicate that genetic factors may predispose to CP of newborns and initial results of related researches infer that several susceptibility genes may contribute to CP's development, masqueraders have a great impact on CP's clinical symptoms.Now, the recent publications related to virulence genes and masqueraders of CP are reviewed.
