Aim To evaluate the effects of fibrinolytic enzyme FⅡ from agkistrodon acutus venom on an experimental model of kidney thrombus induced by lipopolysaccharide(LPS). Methods The model of microvascular thrombosis in the rabbits kidney was performed by the method of Hermida, which was induced by infusing LPS. Treatments were begun simultaneously with LPS infusion, through the contralateral marginal ear vein. Six different groups were established: NS 10 ml?h~-1 was infused as the negative control group, urokinase ~20 000 IU?kg~-1 ?h~-1 as positive control group, FⅡwas infused with the dosage of 0.1(Low-dose), 0.3 (medium-dose),0.6 (high-dose) mg?kg~-1 ?h~-1 . The further rabbits, which were given neither LPS nor FⅡ, were infused with saline solution through both marginal ear veins. Kinney sections were examined for the presence of fibrin microthrombi. The measurement of FDP concentrations was used to assess the degradation of microvascular thrombosis. Results Intense fibrin deposition was also detected and FDP concentrations were (78.21?4.79)% and (84.27?6.21)% at 2 and 6 hours after LPS administration in LPS-control group. Little fibrin deposition was detected and FDP concentration also increased in urokinase control group. A lot of fibrin deposition was detected in Low-dose FⅡ group,little fibrin deposition was detected in medium-dose FⅡ group, and no fibrin deposition was detected in high-dose FⅡ group. Additional all doses of FⅡ led to a significant increase in FDP concentration as compared with LPS-control group (P

Chinese herbal pieces are a key factor to protecting the quality of the clinical efficacy of traditional Chinese medicine (TCM), and it is one of the basic elements of ensuring the quality of TCM and people's usage safety. However, Chinese herbal pieces has massive problem such as adulteration and counterfeit, dyeing and weighting, pesticide residues, heavy metals in excess of the standards, and all the issues are repeated excessive in the clinic treatment. These issues impacted sound development of production, management and use of TCM, but also brings common people hidden trouble for the clinical safety of medication. Protect and improve the quality of the Chinese herbal pieces demand that continue improve quality system, in-depth scientific research, and strengthen self-discipline and other factors. So it is fundamentally to ensure good quality of Chinese herbal pieces with the color, taste and shape by systematic supervision to it from the source, production, management and research, with strengthened implementation and en- forcement of the "3G".

Objective To investigate the effects of icariin, a major active component of traditional Chinese herb Epimedium on schizo-phrenia animal model. Methods MK-801, a N-methyl-D-aspartate (NMDA) receptor antagonist, was intraperitoneally injected into mice to establish a schizophrenia animal model. The open field behavior test infrared detection system was used to measure the mobility of mice in order to find the best optimal dose. 40 mice were randomly divided in to control group, model group, risperidone group and icariin group with 10 mice in each group. The risperidone group and the icariin group were given 0.1 mg/kg risperidone and 50 mg/kg icariin respectively. All groups were injected with 0.6 mg/kg MK-801 0.1 ml intraperitoneally, except the control group. The total distance and the central dis-tance within 210 minutes were tested. Results The total distance and the central distance were significantly longer in the model group than in the control group (P<0.001), and were shorter in the risperidone group than in the control group (P<0.05). The total distance was shorter in the icariin group than in the model group, but there was no significant difference (P=0.065); and the central distance was shorter (P=0.037). There was no significant difference in both total distance and the central distance between the risperidone group and the icariin group (P>0.05). Conclusion Icariin may improve the positive and negative symptoms of schizophrenia mice, which may be beneficial to schizo-phrenia therapy.

Objective To study the risk factors for children with acute central nervous system(CNS)viral in-fection,so that pediatrician may identify children with poor prognosis at early stages of the disease,and provide them with a theoretical basis for clinical treatment. Methods The clinical data of a cohort patients of acute CNS viral infec-tion who were hospitalized at the First Affiliated Hospital of Fujian Medical University between January 2010 and June 2013 were retrospectively collected and analyzed. According to Glasgow outcome scale on discharge,children were di-vided into good prognosis group and poor prognosis group. Clinical data and outcomes were analyzed by using univariate analysis and binary Logistic regression multivariate analysis. Results Three hundred and one cases were enrolled,278 (92. 36% )patients were assigned to the good prognosis group,and 23(7. 64% )patients were assigned to the poor prognosis group. By univariate analysis,the patients in the poor prognosis group had longer duration of sickness before admission,longer time of fever,lower white blood cell count in cerebrospinal fluid,a relatively lower calcium level,con-scious disturbance at the early stage,multiple seizures,convulsive status epilepticus,meningeal irritation sign,muscle weakness,severe changes in electroencephalogram(EEG),and abnormal neuroimaging findings(computed tomography or magnetic resonance imaging,or both)had significant differences between the good prognosis group and the poor short - term outcome groups(all P < 0. 05). By binary Logistic regression multivariate analysis,factors indicating a poor prognosis during the early stage were conscious disturbance at the early stage(0R = 4. 885,95% CI:1. 523 - 15. 670, P = 0. 008),multiple seizures(0R = 6. 352,95% CI:1. 905 - 21. 178,P = 0. 003),severe changes in EEG( 0R =4. 269,95% CI:1. 708 - 10. 666,P = 0. 002),and abnormal neuroimaging findings( 0R = 9. 740,95% CI:2. 360 -40. 192,P = 0. 002). Conclusions Conscious disturbance at the early stage,multiple seizures,severe changes in EEG and abnormal neuroimaging findings are risk factors for acute viral infection of CNS in children.

Objective To study the early diagnostic indices of melioidosis by analyzing 49 cases. Methods Unconditional logistic regression analysis was used to analyze the clinical data of 49 cases of melioidosis and 98 cases of bacterial pneumonia who were admitted in our hospital and Peoples' Hospital of Hainan Province from December 1996 to December 2007. Their social characteristic,background diseases,clinical manifestations,laboratory findings,radiologic examination and complications were studied. Results Background disease (such as diabetes),hepatosplenomegaly,septic shock,sepsis et al were the main causes of melioidosis. Conclusion Chills,fever,hepatosplenomegaly,diabetes mellitus,septic shock and sepsis are all factors that should be considered with melioidosis.
