Objective To classify all the plant pollen allergens, each allergen sequence available was compared with protein family database. After that, the appearance and taxonomic distribution of each protein family could be known. When made reference to evolutionary analysis, a regular rule of the distribu-tion of all plant pollen allergens could be concluded. Methods Protein family memberships of each allergen were assigned by comparing the sequences with the Pfam database. Representative members of the most a-bundant pollen allergen families were compared with the Uniprot database using the BLAST server. Acces-sion number of all the interesting homologous could be obtained and all the sequence information could be ac-quired by Batch Entrez. Finally, the evolutionary trees were drawn with the help of MEGA4.0 software. Re-sults One hundred and sixty-eight pollen allergens were classified into 26 protein families. Profilins, pollen _allerg_1 and EF hands constituted the most abundant pollen allergen families. Profilins and EF hands oc-curred in almost all allergenic plant families, whereas allergenic Expansins, FAD_binding proteins, Amb_V allergens and Thaumatins were confined to single taxon. Conclusion It is concluded that the highly con-served sequences of allergens families such as Profilin may be one of the most important reasons of the cross reactivities in allergic diseases. The classification of pollen allergens may be helpful to clinical practice and basic research.

Objective To investigate the incidence of abnormal thyroid function in pregnant women and explore the significance of thyroid function screening in early pregnancy. Methods We randomly selected 630 cases of pregnant women who received routine inspection in the obstetric clinic in our hospital, and gave them five items of thyroid function screening besides routine check at the same time. Then we statistically analyzed the test results, and followed up 61 cases of pregnant women with hypothyroidism or subclinical thyroid function (hypothyroidism) to learn the treatment and adverse pregnancy outcomes,so as tto explore the correlation between hypothyroidism, subclinical hypothyroidism and adverse pregnancy outcomes. Results In 630 cases of pregnant women,there were 8 cases of hyperthyroidism (1.3%),61 cases of hypothyroidism or subclinical hypothyroidism (9.7%),including 5 cases of hypothyroidism (0.8%), 56 cases of subclinical hypothyroidism (8.9%) .There was statistically significant difference in TSH and FT4 between hypothyroidism group and normal control group ( <0.01) .There was statistically significant difference in TSH,FT4 and TT4 between subclinical hypothyroidism group and normal control group ( <0.05) . In 61 cases of hypothyroidism and subclinical hypothyroidism, 39 patients received levothyroxine therapy,22 received no treatment. The incidence of adverse pregnancy outcomes in the treatment group was significantly lower than the untreated group ( <0.05) . Conclusion Thyroid function testing in 6-20 weeks in early pregnancy has important significance in timely founding gestational thyroid dysfunction, so it should be as routine examination project.

Tea polyphenols (TPs), major biological active constituents of green tea, exert moderate and selective anticancer effects. Molecular mechanisms of TPs in cancer prevention and treatment involve multiple potential molecular targets. TPs inhibit growth factor receptor-mediated signal transduction pathway, decrease the activities of mitogen activated protein kinases and activator protein transcription factor-1, block nuclear factor-kappaB signaling pathway, reduce proteasome activity, lower overexpression of COX-2, subside dihydrofolate reductase and telomerase, and inhibit DNA methylation and matrix metalloproteinases. Furthermore, TPs enhance the inhibitory effect on the growth of cancers by traditional anticancer drugs or targeted antitumor drugs in vitro and in vivo and reverse multidrug resistances of cancer cells to vincristine, doxorubicin, and 5-fluorouracil. Besides, TPs reduce the nephrotoxicity induced by cisplatin, ameliorate irinotecan-induced side effects in the small intestine of mice, and decrease bleomycin-caused DNA damage in human leukocytes. TPs also increase antitumor activity of vaccine through immunological modulation. TPs play roles of the augmentation of antitumor effects, the reversal of multidrug resistance, and the reduction of side effects of chemotherapeutic drugs. TPs could be used as biochemical modulators in cancer therapy.

Method Eighty-two patients with COPD due to phlegm-heat obstructing the lung were randomized into a treatment group and a control group, 41 cases in each group. The control group was given regular Western medications, while the treatment group was intervened by cupping plus Chinese medicinal fumigation in addition to the treatment given to the control group, once a day, 5 d as a treatment course. The therapeutic efficacies were observed after 2 treatment courses. Result The clinical effective rate of the treatment group was higher than that of the control group, with a statistical significance (P<0.05). Conclusion Cupping plus Chinese medicinal fumigation can enhance the expectoration in patients with COPD due to phlegm-heat obstructing the lung.

Expression of PRL receptor mRNA in Jurkat D1.1 cell line was confirmed by RT PCR. CD154 expression of Jurkat cells was significantly increased when these cells were incubated with PHA and recombinant human PRL, suggesting that binding of PRL to its receptor promotes CD154 expression which plays a role in immune regulation.

Objective:To investigate the expression of prolactin receptor(PRLr) in human immune system.Methods:Specimens of human immune system were obtained from both central and peripheral immune organs, including thymus(thymoma), bone marrow, lymph node and peripheral blood mononuclear cells. Specific fragments of PRLr mRNA were obtained through RNA isolation and RT-PCR amplification and confirmed by DNA sequencing.Results:PRLr mRNA was detected from the thymoma, bone marrow, lymph node and peripheral blood mononuclear cells. All the PRLr cDNA fragments generated by PCR were as long as the expected length, which was 276 bp. The sequencing result of the cDNA was identical to the sequence of PRLr cDNA in GeneBank.Conclusion:The study confirmed that prolactin receptor mRNA was expressed in human central immune organs such as thymus and bone marrow and peripheral immune organs such as lymph node and peripheral blood mononuclear cells. This phenomenon provided a biologic structural evidence that neuro-endocrine hormone PRL might play a modulating role on immune cells from receptor's point of view.
