ObJective To measure the level of MDA and SOD in cerebrospinal fluid from patients with cysticercosis indifferent stages and to investigate their effects on this dieases. Methods Forty-nine patients with a single cysticercus incerebral parenchyma and twenty normal controls parlticipated in the study. According to the magnetic resonance imaging(MRI) results, patients were divided into four stages. The level of MDA,SOD in CSF were tested. The data were analyzedwith the software of SPSS. Results The amount of SOD was significantly decreased in all stages except the fourth stage,while the level of MDA was increased in all the stages,and reached its peak in the second stage. There was a negative cor-relation between SOD and MDA. Conclusion The data suggested oxygen free radicals may be a main mechanism of para-site killing.

Objective: To study changes of ultrastructure of atrial endothelial cells during acute atrial fibrillation (AF) in canines, and explore the possible mechanism of AF left atrial thrombosis. Methods: A total of 16 healthy adult mongrel canines were randomly and equally divided into blank control group (only received thoracotomy without pacing) and rapid atrial pacing (RAP) group (established acute AF model). Myocardial tissue of left and right appendage were taken from two groups and received hematoxylin eosin (HE) staining, then myocardial cell morphological changes was observed under ordinary light microscope; morphological changes of appendage endothelial cells was observed under electron microscope. Results: (1) Paroxysmal AF was successfully induced in all canines of RAP group; (2) There were no significant difference in morphology of appendage and endocardial tissue under ordinary light microscope between two groups; 3. Under transmission electron microscope, endothelium cell of appendage tissue presented defect of different extent, and some shedding in RAP group; while endothelial cell layer was complete with absence of necrosis and shedding in blank control group. Compared with blank control group, there was significant rise in endothelial cell incompleteness (12.5% vs. 75.0%) in RAP group, P=0.041. Conclusion: When acute atrial fibrillation occurs, endothelial cell ultrastructure has already changed, which may be related to thrombosis adhered to wall during atrial fibrillation.

[Objective] To observe the dynamic changes of circulating immune complex (CIC) in monkeys infected by simian immunodeficiency virus (SIV). [Methods] Agglutination test of complement-sensitized yeast cell was used to determine the serum CIC level in 30 cases of monkeys, which were infected with SIVmac251 and sampled in different time-points after infection. Sixty-eight cases of normal monkeys were also examined as controls. [Results] After SIV infection, CIC can't be detected in all 30 monkeys until the 4th week, the total positive rate being 30% . In the 8th week, CIC were detected in 46.7% of these monkeys and then declined gradually in the following 12 weeks. Since the 20th week, the CIC in these monkeys maintained lower liter and lower positive rate which was close to that of the normal monkeys (about 10%). [Conclusion] CIC appeared and increased during the primary SIV infection and declined accompanying with the virus clearance from the circulalion. The formation of CIC may not benefit to the control of virus replication and the induction of anti-virus immunity; CIC has a role in the pathogenesis after SIV infection.

OBJECTIVE:To systematically review the effect of ticagrelor versus prasugrel on platelet reactivity,and provide evi-dence-based reference for clinical treatment. METHODS:Retrieved from PubMed,CJFD and Wanfang Database,randomized con-trolled trials(RCT)about the effect of ticagrelor versus prasugrel on platelet reactivity were collected. Meta-analysis was performed by using Rev Man software after data extract and quality evaluation by Cochrane 5.1.0. RESULTS:Totally 17 RCTs were enrolled,involv-ing 2 757 patients. Results of Meta-analysis showed,regardless of Verity Now(VN)detection method [MD=15.43,95%CI(-0.39, 31.25),P=0.06] or vasodilator stimulus phosphoprotein(VASP)detection method [MD=-3.04,95%CI(-8.98,2.90),P=0.32], ticagrelor and prasugrel had the same effects on platelet reactivity under loading dose,the differences were not statistically significant;regardless of VN detection method [MD=-48.94,95%CI(-58.04,-39.84),P<0.001] or VASP detection method [MD=-14.32, 95%CI(-20.45,-8.20),P<0.001],the effects of ticagrelor were better than prasugrel on platelet reactivity under maintenance dose,the differences were statistically significant. CONCLUSIONS:At the loading dose,there was no difference between ticagrelor and prasugrel,but ticagrelor has more benefits than prasugrel under maintenance dose.

Objective To study the drug dosage and time dependency characteristics of high-fructose-high-fat-feeding plus dexamethason for inducing the mouse acute fatty liver model and to optimize the condition of drug induced fatty liver model.Methods Male KM mice were divided into the normal control group and high-fructose-high-fat-feeding plus peritoneal injection of dexamethason group.The mice were killed at 3 different time points.The mouse body mass and liver mass were detected.The liver index was calculated.The serum and liver tissue homogenate TG and serum glucose(GLU) levels were detected.The liver tissue pathological change was observed by HE staining.Total RNA reverse expression related gene was extracted from the liver tissue.The total protein was extracted from the liver tissue and the related protein expression was detected by Western Blot.Results Compared with the control group,blood and liver homogenate TG after 7 d in the dexamethason model group was increased,the liver index was increased,the pathological section displayed that the fatty liver was formed.RT-PCR showed that lipid metabolism related gene expression had obvious change.Western Blot showed that SIRT1 was significantly decreased.But with the dexamethason dosage decrease and time extending,the fatty liver related indexes were decreased,lipid metabolic gene PPAR,FOXO3 and FXR were gradually increased,while LXR was gradually decreased and protein SIRT1 was gradually increased.Conclusion High-fructose-high-fatfeeding plus peritoneal injection of dexamethason could establish the mouse acute fatty liver model,moreover the model maintenance has dependency on dexamethason dosage and medication time,which has a guidance significance for the drug interventional experiment.

Objective To investigate the cause,therapeutic strategy,methods of treatment and clinical results for the rectovaginal fistulas(RVF)after rectal cancer operations.Methods The clinical data of 14 female patients with RVF after rectal cancer operations were examined retrospectively.According to therapeutic strategy,all patients were divided into two groups,A group and B group,which were seperately performed traditional treatment,and progynova in combination with non-operative treatment.Results Among 10 patients in A group,8 patients were performed feacal diversion stoma,and 7 patients with RVF cured naturally,then performued colostomy reversal and restoration of bowel continuity,the other 2 cases were performed non-operative treatment for refusing feacal diversion stoma.Among 4 patients in B group,3 cases with RVF healed naturally during 1.5 to 2 months,one case secondary to rectal anastomosis was performed feacal diversion stoma for rectovaginal fistula without signs of healing.Conclusion RVF is a rare but serious complication after resection of rectal carcinoma,which is taken by the treatment strategy of progynova in combination with non-operative treatment,not only can promote the natural healing of RVF obviously,but also can shorten the healing time greatly.Feacal diversion stoma can be used while the treatment is failure.
