Objective To explore the neuroprotective mechanism of propofol by comparing the influence of propofol and isoflurane on inflammatory cytokines ( TNF-α、IL-1、ICAM-1 ) in patients with intracranial tumors. Methods One hundred and sixty-eight patients with intracranial neoplasm were randomly divided into two groups:the propofol ( Group P) and isoflurane (Group I),84 cases in each. Patients were given with propofol (3-6 μg·mL-1) by plasma target-controlled infusion or with continuously inhaled isoflurane ( 1%-2%) , respectively. The serum levels of TNF-α, IL-1 and ICAM-1 were detected before anesthesia and at 0,24,and 48 h after operation. Results The serum levels of TNF-α,IL-1 and ICAM-1 were significantly increased after operation as compared to baseline in both groups. The serum level of TNF-α was(69. 11±8. 95) and (76. 26±11.28) μg·mL-1,IL-1 was(21.57±3.19) and (29.58±4.38) ng·L-1,and ICAM-1 was (1.63±0.24)and (1.94±0.29) g·L-1 at 24 h post operation in Group P and Group I,respectively. These inflammatory cytokine levels were significantly higher in group I compared to group P at 24 and 48 h after operation (P<0. 05 or P<0. 01). Conclusion The target-controlled infusion of propofol brings about lower level of inflammatory reaction than isoflurane inhalation in patients with intracranial neoplasm,which may attribute to the mechanism of brain protection against injury.

Objective To explore the regulation and effect factors of arsenic expose and arsenic methylation level, then to provide a reference for study the function of arsenic metabolism in a arsenic poisoning process. Methods A meta-analysis was performed by two researchers. Twenty-five papers satisfying our priori eligibility criteria were included by searching Cochrane library, Pubmed, Springer, Embase and China National Knowledge Infrastructure. Based on the results of heterogeneity, a random or fixed effects model was chosen for the meta-analysis. Results The results showed that the following arsenic metabolites increased (all P<0.01) following arsenic exposure: inorganic arsenic [iAs; standardized mean difference (SMD): 1.07; 95% confidence interval (CI):0.61 - 1.53)], monomethyl arsenic (MMA; SMD: 1.10; 95% CI: 0.81 - 1.40), dimethyl arsenic (DMA; SMD: 2.50;95%CI:1.50-3.69), and total arsenic (TAs, SMD:3.10;95%CI:2.13-4.07). Additionally, the percentages of iAs (iAs%; SMD: 1.00; 95% CI: 0.60 - 1.40) and MMA (MMA%; SMD: 0.49; 95% CI: 0.21 - 0.77) also increased, while the percentage of DMA (DMA%; SMD: - 0.55; 95% CI: - 0.80 - - 0.31) decreased (P<0.01). The primary methylation index (PMI; SMD: - 0.57; 95% CI: - 0.94 - - 0.20), and secondary methylation index (SMI;SMD: - 0.27; 95% CI: - 0.46 - - 0.09) decreased (all P< 0.01). Compared to female, male had higher MMA%(SMD:0.44;95%CI:0.35-0.52), lower DMA%(SMD:-0.33;95%CI:-0.38--0.28) and SMI (SMD:-0.36;95%CI:-0.53--0.19). The smoker had higher MMA%(SMD: 0.22; 95%CI: 0.07 - 0.37) and lower DMA%(SMD:-0.16;95%CI: - 0.26 - - 0.05). The drinker had higher MMA% (SMD: 0.17; 95% CI: 0.07 - 0.27) and lower DMA%(SMD:-0.24;95%CI:-0.39--0.10). The older people had higher MMA%(SMD:-0.23;95%CI:-0.40--0.06). In addition, the body mass index may influence the percentages of MMA (SMD: - 0.18; 95% CI: - 0.31 - - 0.04, P < 0.01). Conclusion Arsenic exposure, smoking, drinking, and older age can reduce the capacity of arsenic methylation. Arsenic methylation is more efficient in women than in men.

Objective To compare the effects of non-steroidal anti-inflammatory drugs (NSAIDs) and free radical scavengers (FRS) on formation of traumatic heterotopic ossification (HO) in rabbits. Methods 48 New Zealand rabbits were randomly divided into control group (n=12), NSAIDs group (n=12), FRS group (n=12) and combination group (n=12). The model of traumatic HO was established, and the NSAIDs group, FRS group and combination group were administered indometacin intragastrically, edaravone intravenously and both, respectively, while the control group was administered normal saline for 4 weeks. The incidence and severity of HO were observed with X-ray 8 and 12 weeks after modeling. Results 8 and 12 weeks after operation, the incidence of HO was 33.3% and 41.7% in the NSAIDs group, 43.0% and 45.8% in the FRS group, 29.2% and 37.5% in the combination group, and 70.8% and 75.0% in the control group, respectively. The incidence and severity of HO in all the treatment groups were significantly less than those in the control group (P<0.05), and there was no significant difference among the treatment groups (P>0.05). Conclusion The systemic application of FRS may prevent the formation of HO effectively, similar with the NSAIDs. There is no synergistic effect between them.
