Objective To investigate the protective effects of Xuebijing(XBJ)on the injury of vascular endothelial cells(VEC)induced by lipopolysaccharide (LPS),and to study the mechanisms of the production of nitric oxide (NO)and the expressions of inducible nitric oxide sytnhase (iNOS)and signal transduction under XBJ intervention condition.Methods The cultured VEC were divided into control group, LPS (1 mg · L-1 )group, LPS (1 mg·L-1)+XBJ(25 g·L-1)group,LPS(1 mg·L-1)+pyrrolidine dithiocarbamate(PDTC,20μmol·L-1) group;XBJ and PDTC were administrated 1 h before incubation of with LPS.Western blotting method was used to detect the expressions of iNOS and NF-κB p65 protein.The level of NO in the supernatant was measured by Griess reagent.Results Comparaed with control group,the NO level and the expression levels of iNOS protein and NF-κB p65 protein in VEC in LPS group were significantly increased(P<0.01).Compared with LPS group,the NO level and the expression levels of iNOS protein and NF-κB p65 protein in VEC in LPS+XBJ group were significantly decreased (P<0.05 or P<0.01);the NO level and the expression levels of NF-κB p65 protein and iNOS protein in VEC in LPS+PDTC group were significantly decreased(P<0.05 or P<0.01).There were no significant differences of the NO levels and the expression levels of iNOS protein between LPS+XBJ group and LPS +PDTC group (P>0.05),but the expression level of NF-κB p65 protein in LPS+PDTC group was lower than that in LPS+XBJ group(P<0.05).Conclusion XBJ can inhibit the production of NO and the expression of iNOS protein in VEC;its mechanism may be related to inhibiting the activation of NF-κB to control inflammation.

Objective To investigate the changes in acetylation of histone in the spinal dorsal horn in a rat model of persistent postoperative pain.Methods Ninety-six malc Sprague-Dawley rats,weighing 200-250 g,aged 6-8 weeks,were randomly divided into 2 groups (n=48 each) using a random number table:sham operation group (group S) and persistent postoperative pain group (group PPP).The rat model of persistent postoperative pain evoked by skin/muscle incision and retraction was established according to the method described by Flatters.After the rats were anesthetized with intraperitoneal chloral hydrate,the skin and superficial muscle of the medial thigh were incised and retractors inserted.This tissue was retracted for 1 h.The mechanical paw withdrawal threshold (MWT) was measured at 1 day before operation and 1,3,7,14,and 21 days after operation.Four animals were sacrificed in each group after measurement of MWT at each time point for detection of acetylated histone H3 (Ac-H3) and acetylated histone H4 (Ac-H4) expression (by Western blot analysis) and the number of Ac-H3 and Ac-H4 positive cells in the spinal cord horn (by immunofluorescence histochemistry).Results Compared with group S,the MWT was significantly decreased at 3,7,14 and 21 days after operation,the expression of Ac-H3 and Ac-H4b was significantly down-regulated at 3,7 and 14 days after operation,and the number of Ac-H3 and Ac-H4 positive cells was significantly decreased at 7,14 and 21 days after operation in group PPP (P＜0.05 or 0.01).The MWT,expression of Ac-H3 and Ac-H4b,and the number of Ac-H3 and Ac-H4 positive cells were significantly higher at 21 days after operation than at 14 days after operation in group PPP (P＜0.05).Conclusion Acetylation of histone in the spinal dorsal horn is decreased after operation,which may be involved in the development and maintenance of persistent postoperative pain in rats.

Objective To explore the correlated factors of bilirubin neurotoxicity. Methods From July 2007 to October 2007, 53 hospitalized patients with jaundice in neonatal ward of Peking University Third Hospital were enrolled in the study. The relationship between serum free bilirubin and parameters of brainstem auditory evoked potential(BAEP) was analyzed to screen the sensitive index of bilirubin neurotoxicity. Multivariate analysis was conducted between the sensitive parameter and various factors. Results Partial correlation analysis showed that the wave Ⅴ latency was positively correlated to serum free bilirubin(r=0. 228, P= 0. 020) after the corrected gestational age was controlled. There were no correlation between other latencies or interwave intervals and serum free bilirubin. Linear regression showed the equation was wave Ⅴ latency= 9.721-0. 082 × corrected gestational age+0. 064 × bilirubin/albumin+ 0. 504 × acidemia(F= 7. 534, P＜0.01). Conclusions Wave Ⅴ latency is the sensitive indicator of bilirubin neurotoxicity, which is correlated with the value of bilirubin/albumin and acidemia.

Objective To analyze the characteristics in the incarcerated inm ate’s death, investigate the m ain cause of death of the incarcerated inm ate and provide som e inform ation for forensic investigation. Methods The cases from the forensic m edical center of Shanxi Medical U niversity from 2005 to 2013 were selected. The statistical analysis w as perform ed by using the incarcerated inm ate’s gender, age, cause of death, m anner of death, and disease as the m arkers. Results There were 100 men, 5 w omen in the 105 incarcerated inm ates;the age range w as from 16 to 65 years;Inm ates were mostly died of nat-ural diseases, m ainly in the respiratory and cardiovascular diseases;the m ain unnatural death w as suicide w ith a rate of 54.5%. Conclusion Atpresent, most incarcerated inm ate’s death are due to natural dis-eases. The prison should im prove incarcerated inm ate’s lives, w ork and health care conditions, and strengthen supervision of law enforcement.

Objective:To establish a method for the determination of phenyl salicylate in compound titanium dioxide cream. Meth-ods:The HPLC assay was carried out on an Agilent Zorbax SB C18 (250 mm × 4. 6 mm, 5 μm) column with methanol -water (78∶22) as the mobile phase. The sample was detected at 308 nm with a UV detector. The column temperature was set at 25 ℃ and the flow rate was 1. 0 ml·min-1 . Results:Phenyl salicylate could isolate from the other materials by HPLC. The linear range of phenyl salicylate was 59.460-198.200 μg·ml-1(r=0.999 5). The recovery was 101.84% with RSD of 0.64%(n=9). The content of phenyl salicylate in 3 batches of compound titanium dioxide cream was 107. 7%, 107. 5% and 109. 8%, respectively. Conclusion:The method is simple, rapid, exclusive, accurate and sensitive, which is suitable for the determination of phenyl salicylate in com-pound titanium dioxide cream.
