OBJECTIVETo establish and optimize the proteomic analysis of protoscoleces-specific antigens from Echinococcus granulosus. To provide a foundation for identifying specific antigens in the soluble proteins of E. granulosus protoscoleces for further research.

METHODSBrood capsules were collected aseptically from fertile E. granulosus cysts from the livers of an infected patient. The fertile E. granulosus cysts were fractured, and protoscoleces were collected by centrifugation. The soluble proteins of protoscoleces were acquired using the 2D Quant kit according to the manufacturer's instructions. We employed two-dimensional electrophoresis (2-DE) combined with immunoblot assay (Western blot) to analyze the soluble components of E. granulosus protoscoleces antigens. The 2-DE and immunoblot maps obtained were analyzed with PDQuest 8.0 image analysis software.

RESULTSAbout 233 soluble protein spots were identified with Coomassie-stained gels. Most of the proteins had a molecular weight of 16,000 Da to 117,000 Da, and an isoelectric point value of 3.0 to 10.0. 2-DE immunoblot was conducted and 57 specific antigen spots were observed, among which 23 spots were identified.

CONCLUSION2-DE combined with Western blot is the key to successful proteomic analysis and presents a new possibility for searching the specific E. granulosus protoscoleces antigens.

Chlorella pyrenoidosa No.2 was screened from five species of microalga Chlorella sp. for its higher lipid yield. Effects of medium components and culture conditions on cell growth as well as lipid ac-cumulation of C. pyrenoidosa No.2 were investigated and the results showed that the optimum medium rec-ipe was 20.0 g/L glucose,0.08 g/L glycine,1.0 g/L K2HPO4?3H2O,0.4 g/L MgSO4?7H2O and 0.004 g/L FeSO4?7H2O. The optimum culture temperature,initial pH,shaking rate and light intensity were 28℃,6.0,130 r/min and 650 Lux,respectively. Biomass and lipid content increased from 3.73 g/L and 40.15% to 6.56 g/L and 59.90% when Chlorella pyrenoidosa No.2 was cultivated under the above optimal conditions for 7 days,with lipid yield raised by 162%. Chlorella pyrenoidosa No.2 could produce lipid with xylose as carbon source,and so is potential for lipid production from renewable materials such as lignocellulose. GC analysis demonstrated that the fatty acid composition of the lipid was similar to that of vegetable oil and its unsaturated fatty acid content reached around 71%,thus it is a promising material for biodiesel production.

Aim To explore the effects of Baixiangdan capsule on learning and memory in PMS rat model with liver-qi invasion syndrome. Methods Liver-qi inva-sion rat model was prepared using foot-shock and noise stimulation, and then the model was treated with drugs, finally all the group of rats were evaluated using open-field test. We also detected learning and memory function of PMS liver-qi invasion rats model using Y-maze, new-object recognition and Morris water maze test. Results Compared with the normal group, the total distance increased significantly, number of crosses into the central area and duration of movement in the central area decreased significantly in model group. The total distance decreased significantly, number of crosses into the central area and duration of movement in the central area increased significantly in Baixiang-dan treatment group compared to the model group, and the total distance decreased significantly in fluoxetine treatment group compared to the model group. Com-pared with the normal group, DI decreased significant-ly in model group, and DI increased significantly in Baixiangdan treatment group. During place navigation training, the model group’ s escape latency was obvi-ously delayed on 2nd, 4th day. Compared with the model group, Baixiangdan and fluoxetine treatment group’ s escape latency was obviously reduced. During spatial probe test, compared with the normal group, the escape latency was obviously delayed, and the number of crossing platforms was significantly reduced in the model group. Compared with the model group, the number of crossing platforms significantly increased in Baixiangdan treatment group. Conclusion PMS liver-qi invasion rat model presents learning and memo-ry damage, which could be improved by Baixiangdan capsules, and the treatment effect may be superior to that of fluoxetine.

Objective To produce a hybridoma secreting stable monoclonal antibodies against Aβ22-35 and to develop a detection method for the assay of Aβ. Methods Spleen cells from Balb/cmice immunized with Aβ22-35-KLH were fused with mouse myeloma cells SP2/0. The techniques of immunoprecipitation and western blotting plus ECL were used to investigate the levels of Aβ in the rat brain. Results Two strains of hybridomas (3A8 and 3B2) secreting stable monoclonal antibodies raised against Aβ22-35 were obtained. The subtypes of Aβ22-35 were IgG3. The levels of Aβ in young and older rat brain were 9.8±2.8 and 13.36±2.65 (pmol/12mg brain tissues, x±s), respectively. Conclusion The Aβ22-35 mAb obtained had high titres and specificity. The levels of Aβ in the older rat brain were significantly increased as compared with the young one (P＜0.05).

?AIM:To investigate the measurement of central anterior chamber depth ( ACD ) in patients with acute primary angle - closure glaucoma ( APACG ) with A - scan ultrasound, Pentacam and ultrasonic biological microscope ( UBM) .?METHODS: Thirty-five patients (35 eyes) with APACG were selected, of whom central ACD were measured with A-scan ultrasound, Pentacam and UBM.?RESULTS: The measurement values of ACD with A-scan ultrasound, UBM and Pentacam were 1. 5633±0. 2089, 1. 5783 ± 0. 2067, 1. 6275 ± 0. 2296mm, which was equal variance tested by the homogeneity of variance, and was significant different by multiple comparision (F=4. 074, P=0. 026). The difference of ACD between the two groups of A-scan ultrasound and UBM, A-scan ultrasound and Pentacam, UBM and Pentacam were statistically significant ( P = 0. 032, 0. 023, 0. 012 ). Altman- Bland analysis showed that the three methods were not consistent with each other.?CONCLUSION: The ACD value of the APACG with the three methods is the largest using Pentacam, followed by UBM and A - scan ultrasound. In clinical the three methods with different advantages can complement each other, but cannot be replaced. In order to obtain more accurate results, we should combine the advantage and make comprehensive analysis.
