3.Analysis of protoscoleces-specific antigens from Echinococcus granulosus with proteomics combined with Western blot.
Biomedical and Environmental Sciences 2012;25(6):718-723
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).

Background Some researching results of sodium hyaluronate eye drops treating dry eye have been reported home and abroad.To evaluate these results using the method of evidence-based medicine (EBM) has an important clinical significance.Objective This secondary study was to systematically evaluate the efficacy of sodium hyaluronate eye drops for the treatment of dry eye.Methods Meta analysis was adopted in this study.The electronic bibliographic databases were searched according to the prescribed strategy,including Medline,PubMed,VIP,CBM,CNKI,Wanfang Data using the method of Cochrane systematic review.The literature published time was limited from the commencement of each database to December,2011.Randomized controlled trials (RCTs) of sodium hyaluronate eye drops treating dry eye were included and the methodological quality of the RCTs was assessed by two evaluators using Jadad measuring scale,and homogeneous evaluation by Meta-analysis was performed.Statistical analysis of clinical data was performed using RevMan 5.0 software provided by the Cochrane Collaboration.With odds ratio (OR) value as the effect index,the randomized effect model was used to analyze the clinical heterogeneity.Results A total of 4 RCTs involving 686 patients were included.Jadad scale evaluation showed 7 points in 2 literature,4 points in 1 literature and 2 points in 1 literature.In all the RCTs,344 patients with dry eye were treated using sodium hyaluronate as the sodium hyaluronate eye drops group,and 342 dry eyes applied placebo,normal saline solution,hydroxymethyl cellulose,hydroxypropyl methyl cellulose respectively as the control group.Meta-analysis indicated that the total effective rate (OR) was 2.55 with the 95% confidence interval (CI) 0.94-6.93.The symptoms were improved in 183 cases in the experiment group and 130 cases in the control group.No significant difference was found in the OR between the sodium hyaluronate eye drops group and the control group (Z =1.84,P=0.07).Conclusions Meta-analysis indicates that sodium hyaluronate eye drops can improve the symptom of dry eye,but have no significence with the control group.However,owing to fewer number and uneven quality of included RCTs,the large sample size and multicenter of RCTs is still needed to verify the superiority of sodium hyaluronate eye drops for dry eye.
