This study was aimed to investigate the seed protein of different forms ofTrichosanthis fructus from Shandong province. UV analyzer was used to analyze the seed protein content. PAGE fingerprint was drawn by Biosens Gel Imaging System software. The Jaccard coefficient was worked out by using NTSYS-pc software. A cluster dendrogram of different samples was established based on unweighted pair-group method with arithmetic means (UPGMA). The results showed that the content of different samples was obviously different. But there were many common bands in the fingerprints of PAGE. It was concluded that the content of seed protein cannot be used as the main index to evaluate the quality ofTrichosanthis fructus. The common bands in fingerprints of PAGE can be used to identifyTrichosanthis fructus.

This study sought to amplify the CDS region of p55-v0 and p55-v3 gene in Pneumocystis carinii (PC) and to analyze their sequences.The total RNA extracted from PC- infected lungs of rats were used as the template to amplify these genes by RT-PCR.The amplified products were connected to T-vector and transformed into E.coli DH5α.The recombinant T-vectors were selected in LB culture medium containing ampicillin.Then the positive clones of recombinants were identified by PCR and digested by restrictive endonuclease.After that the recombinant were sequenced and analyzed.It was found that the CDS region of p55-v0 gene contained 1245 bps,encoding 414 amino acids.The homology between this sequence and the one reported previously in nucleotide and amino acid were 99.8% and 100% respectively.Meanwhile,the CDS region of p55-v3 contained 1053 bps,encoding 350 amino acids.As compared with GenBank,the homology in nucleotide and amino acid was 99.9% and 100% respectively.However,the similarity in nucleotide between p55-v3 and p55-v0 was just 20.9%.In this study,the CDS regions of p55-v0 and p55-v3 gene were cloned successfully,and the high homology was found between p55-v0,p55-v3 and the one reported previously by sequence analysis,p55-v3 was different from p55-v0 in nucleotides and amino acids.This result would provide a basis for comparison of immunologic functions so as to explore the mechanism of action of the p55-v3 gene.

This study was aimed to explore recognition models and to establish statistical pattern recognition methods of cold-hot property markers based on lipid components GC-MS chromatogram of Chinese materia medica (CMM). GC-MS fingerprints of lipid components contained in 60 kinds of cold or hot property of CMM were used as the research object. The database was established. Five types of model establishment strategies were compared. Optimal modeling patterns were screened for the identification of herbal property markers of lipid components GC-MS chromatogram. The results showed that support vector machine (SVM) was the best model to discriminate cold or hot property among 60 types of CMM, which were able to effectively mark the characteristic area. The strongest markers tending to cold property was at the retention time of 61.550 min, while the strongest markers tending to hot property was at the retention time of 31.395 min. It was concluded that cold or hot property of CMM had close relationship with lipid components. The lipid component was one of the material bases of CMM. The mathematical statistical model based on material base and herbal property can be used to identify and predict the cold and hot property of CMM.

Conclusion: TCM syndromes of primary hyperlipemia had some relation with laboratory indices. The lipemia laboratory indices can be one of the objective basis of TCM diagnosis. The main syndromes were stagnation of phlegm-turbid and syndrome of yang deficiency of both of spleen and kidney, the main pathogenesis were deficiency of spleen and kidney, intermingled phlegm and blood stasis. The main treatment methods were invigorating spleen and tonifying kidney, supplementing qi and nourishing heart, promoting blood flow and dissipating phlegm.

Objective To track superparamagnetic iron oxide (SPIO)-labeled pancreatic islet cells in rats using 3.0T magnetic resonance imaging (MRI), and to detect the survival and rejection of grafts after transplantation. Methods Twenty male Wistar rats and 5 male Lewis rats were included in the study. SPIO-labeled pancreatic islet cells were tracked using a GE 3.0T Signa Excite MRI scanner with an animal coil. The images of SPIO-labeled islet cells in rats after transplantation were compared with those of the unlabeled ones. FSE T2WI sequence and GRE T2*WI sequence were used for the detection. The sensitivity of images for detection of grafts was also compared. SPIO-labeled pancreatic islet cells isolated from Wistar and Lewis rats were transplanted into the liver of Wistar rats. Afterwards, the survival and rejection of islet cells were observed sequentially in these two growps. The rats in the syngeneic group were sacrificed 3 months post-transplantation, while the rats in the allogeneic group were sacrificed 3 weeks post-transplantation. MRI of the grafts were correlated with the pathological results. Results SPIO-labeled pancreatic islet cells were seen on MRI as distinct homogenous, hypointense spots in the liver. GRE T2*WI were more sensitive to the detection of SPIO-labeled islet cells than FSE T2WI. The relative count of hypointense spots in the syngeneic group were (90.03±9.52)%, (92.87±18.21)% and (86.25±24.81)%, respectively at 1 week, 2 weeks and 3 weeks after transplantation, while the relative count in the allogeneic group were (41.40±15.41)%, (33.41±14.01)% and (23.58±16.78)%, respectively. The difference between these counts was statistically significant (P<0.01). Iron particles were detected only in the SPIO-labeled cells. Three months post-transplantation, the grafts were found well-preserved in the liver of the rats of the syngeneic group, while only a few grafts were found in that of the allogeneic group. Conclusions MRI can be used to track SPIO-labeled islet cells in vivo, and has significant value in detecting the survival and rejection of grafts after transplantation in rats.
