Objective To compare the values of a screening methods by OC-Hemodia and chemical fecal occult blood test (COB) for colorectal cancer in elderly people. Methods The screening programme targeted colorectal cancer in old people was conducted on 1 100 participants aged 60-92 years (mean was 81.3 years). All subjects received OC-Hemodia and COB examinations. Positive subjects were examined by colonoscopy and/or barium enema. Out of 1 100 subjects 1 046 were followed up in the next five years. Results Among 1 100 subjects, 231 subjects (21.0%) were positive by OC-Hemodia test and 159 subjects (14.5%) were positive by COB. There was a significant difference in positive rate between OC-Hemodia test and COB (P

The purpose of this study is to explore the feasibility of wheat germ agglutinin (WGA) modified liposome as a vehicle for ophthalmic administration. Liposome loaded with 5-carboxyfluorescein (FAM) was prepared by lipid film hydration method. WGA was thiolated and then conjugated to the surface of the liposome via polyethylene glycol linker to constitute the WGA-modified and FAM-loaded liposome (WGA-LS/FAM). The amount of thiol groups on each WGA molecule was determined, and the bioactivity of WGA was estimated after it was modified to the surface of liposome. The physical and chemical features of the WGA-modified liposome were characterized and the ocular bioadhesive performance was evaluated in rats. The result showed that each thiolated WGA molecule was conjugated with 1.32 thiol groups. WGA-LS/FAM had a mean size of (97.40 +/- 1.39) nm, with a polydispersity index of 0.23 +/- 0.01. The entrapment efficacy of FAM was about (2.95 +/- 0.21)%, and only 4% of FAM leaked out of the liposome in 24 h. Erythrocyte agglutination test indicated that after modification WGA preserved the binding activity to glycoprotein. The in vivo ocular elimination of WGA-LS/FAM fitted first-order kinetics, and the elimination rate was significantly slower than that of the unmodified liposome, demonstrating WGA-modified liposome is bioadhesive and suitable for ophthalmic administration.

Objective To study the changes and significance of serum beta 2-microglobulin(?2-MG),cytocine interleukin-2(IL-2) in the clinical progress of childhood idiopathic thrombocytopenic purpura(ITP).Methods One hundred and ten patients of childhood ITP were chosen for the test group(70 cases of primary ITP and 40 cases of recurrent ITP),and 110 normal children for the control group.Levels of serum ?2-MG and IL-2 were determined by radioimmunoassay kit and analysed with two sample t-test.Results Among the patients,the serum IL-2 levels were significantly lower and serum ?2-MG levels were significantly higher than those in control group(P0.05).Conclusion Determining serum IL-2 and ?2-MG levels has important significance to reflect the progress of disease and direct treatment.

In this paper, the popular domestic varieties and quality standard of Scrophulariaceae plants used in Tibetan medicine were analyzed. The results showed that there were 11 genera and 99 species (including varieties), as well as 28 medicinal materials varieties of Scrophulariaceae plants were recorded in the relevant literatures. In relevant Tibetan standards arid literatures, there are great differences in varieties, sources, parts, and efficacies of medicinal plant. Among them, about 41.4% (including 41 species) of endemic plants, about 15.2% (including 15 species) of the original plants have medicinal standard legal records, except the medicinal materials of Scrophalaria ningpoensis, Lagotis brevituba, Picrorhiza scrophulariiflora, Veronica eriogyne general, most varieties have not completed quality standard. Consequently it is necessary to reinforce the herbal textual, resources and the use present situation investigation, the effects of the species resources material foundation and biological activity, quality standard, specification the medical terms of the plants, and promote Tibetan medicinal vareties-terminologies-sources such as the criterion and quality standard system for enriching the varieties of Tibetan medicinal materials and Chinese medicinal resources.

In this paper, the domestic varieties and quality standard of Leguminosae medicinal plants used in Tibetan medicine were analyzed. The results showed that there were 36 genera and 142 species (including varieties), as well as 64 medicinal materials varieties of Leguminosae plants were recorded in relevant literatures. In relevant Tibetan standards and literatures, there are great differences in varieties, sources, used parts, and efficacy of medicinal plants. Among them, about 38.0% (including 54 species) of the endemic plants, about 25.4% (including 36 species) of the original plants have medicinal standard legal records, except 9 kinds of traditional Chinese medicine general quality standard more fairly completed, the most varieties have only description about characters, identification, etc. Therefore it is necessary to reinforce study for the herbal textual, resources and the use present situation, chemical components and biological activity, quality standard, medicinal terms specification, to promote establishment of quality standard system for variety-terminologies-sources of Tibetan medicinal plants.
