Objective To investigate the efficacy and safety of oxcarbazepine combined with levetirac-etam on children with epilepsy. Methods According to different treatments, 62 cases of children with epilepsy were divided into the OXC group (treated with oxcarbazepine, 40 cases) and the OXC combined with LEV group (treated with oxcarbazepine and levetiracetam, 20 cases). Then the therapeutic efficacy, EEG changes and ad-verse reactions of patients in the two groups were studied. Results The total efficacy was 87.5% in the OXC group, and was 95.5% of the OXC combined with LEV group, with no significant difference. EEG improvement rate was 52.5% in the OXC group and 81.8% in the OXC combined with LEV group , with significant difference (P < 0.05). The rate of adverse reactions in the OXC combined with LEV group was lower than that in the OXC group (P < 0.05). Conclusion Both levetiracetam and oxcarbazepine has good curative effect on children with epilepsy , but combination with levetiracetam can significantly decrease the epileptic discharges on EEG , with higher security.

AIM:To observe the influence of Chuanbaiqufeng Capsule(Rhizoma Chuanxiong,Radix Paeoniae alba,Herba Schizonepetae,etc.) on the primary trigeminal neuralgia of the model rat.METHODS:Chuanbaiqufeng Capsule was taken to treat the primary trigeminal neuralgia and the pain after chronic constriction injury,and then compared with the control contrast group and the Carbamazepine group.RESULTS:Chuanbaiqufeng Capsule could raise the content of substance P and 5-HT in the rats' brain of the primary trigeminal neuralgia.But for the rat's model after chronic constriction injury,Chuanbaiqufeng Capsule could make the pain threshold risen(P

Objective To study the chemical constituents from mycelium of marine fungus Aspergillus versicolor.Methods The compounds were separated by column chromatography and their structures were elucidated based on chemical and spectral analysis. Results Seven compounds have been isolated from the acetone and methanol extracts from the mycelia of Aspergillus versicolor. Their structures were determined as sterigmatocystin (I), 6-methoxysterigmatocystin (II), averufin (III), tyrosine (IV), 3-methyl-pyrrolopiperazine-2, 5-dione (V), 3-isopropyl-pyrrolopiperazine-2, 5-dione (VI), carbamide (VII). Conclusion Compounds IV,V and VI were isolated for the first time from this genus of marine fungi.

In the structural determination of natural glycosides, nuclear magnetic resonance (NMR) is an important approach in determining the configuration of glycoside bond. The test of coupling constant of the anomeric proton and chemical shift of the anomeric carbon are two common methods, but these methods are not suitable for some sugars. For those sugars, detailed 13C NMR analysis is an alternative choice. This paper summarizes the characteristics of 1H and 13C NMR data of the common monosaccharides published in the literatures, in order to search an approach to determine the configuration of glycoside bond.

Aim To explore the protective effects of in-terleukin-17 ( IL-17 ) monoclonal antibody ( mAb ) on bleomycin-induced pulmonary fibrosis rats and the re-lated mechanisms. Methods Seventy-five male SD rats were randomly divided into normal control group, sham operation group, model group, non-specific IgG group and IL-17 mAb group. Each group included fif-teen rats. Rats in the latter three groups were intratra-cheally administered with bleomycin A5 to establish pulmonary fibrosis model, whereas the ones in sham operation group were treated with the same volume of physiological saline. On day 7, 14 and 21, rats in non-specific IgG group and IL-17 mAb group were in-jected with non-specific IgG and IL-17 mAb, respec-tively,through the caudal vein. However,the ones in the other groups were administered with the same volume of physiological saline. All rats were sacrificed on day 28. Pulmonary tissues were then removed, and HE and Masson staining was performed. The contents of IL-17, IL-6 and tumor necrosis factor-α ( TNF-α) in pulmo-nary tissues were measured by enzyme linked immu-nosorbent assay ( ELISA ) . Western blot was used to analyze the pulmonary tissues protein expression of nu-clear factor-κB ( NF-κB) p65 in the nucleus as well as collagen type I ( Col Ⅰ) and collagen type III ( ColⅢ) in the whole cells. The levels of Col Ⅰ and ColⅢ in the pulmonary tissues were detected by fluores-cence real-time quantitative PCR. Serum was separa-ted, and the concentrations of procollagen type 1 carboxyterminal propeptide ( PICP ) and procollagen type III aminoterminal propeptide ( PIIINP ) in serum were then measured by ELISA. Results The severity of alveolitis and pulmonary fibrosis was lower in IL-17 mAb group than that in model group and non-specific IgG group ( P <0. 01 ) . In comparison with normal control group and sham operation group, pulmonary tissues IL-17, IL-6 and TNF-α contents, NF-κB p65 protein expression in the nucleus, Col Ⅰ and Col ⅢmRNA and protein levels, and serum PICP and PIIINP concentrations were significantly increased in model group and non-specific IgG group ( P<0. 01 ) . Follow-ing treatment with IL-17 mAb, the above indicators were significantly decreased as compared to model group and non-specific IgG group ( P<0. 01 ) . How-ever, there was no significant difference in these indi-cators between non-specific IgG group and model group ( P >0. 05 ) . Similar results were also seen between sham operation group and normal control group ( P >0. 05 ) . Conclusion IL-17 mAb protects rats from pulmonary fibrosis by inhibiting inflammatory response via downregulating NF-κB expression and decreasing collagen synthesis in the pulmonary tissues.
