RESUMO
Medicinal botanical gardens play important roles in promoting the development of TCM industry. With the advancing of the construction of the national medicinal plant garden system, the upgrading construction work for Huazhong Medicinal Botanical Garden, one of its members, is grasping to be carried on. While it is believed that there is a tremendous potential development in the combination of selenium and Chinese herbal medicine. In this article, the significance of selenium for Huazhong Medicinal Botanical Garden was investigated and then the routes to highlight selenium characteristics in its upgrading construction were put forward as follows for some responsibility department as reference: (1) Concentrating on the background investigation and conserving selenium resources;(2) Selecting and breeding special germplasm materials associated with selenium for selected key species; (3) Aiming at the specific efficiency and screening selenium-enriched medical plants; (4) Selecting large varieties of TCM and carrying out the research of selenium-rich technical ways of artificial cultivation; (5) Propelling the research and development of selenium-containing health products, based on resources industrialization; (6) Constructing new specialized garden for selenium-enriched medical plants.

RESUMO
<p><b>OBJECTIVE</b>To study the association between HLA-DRB1 alleles and familial hepatitis B.</p><p><b>METHODS</b>HLA-DRB1 alleles of 151 people in the familial hepatitis B families were detected,by using the the polymerase chain reaction-sequence specific oligonucleotide probing (PCR-SSOP) technique.</p><p><b>RESULTS</b>The allele frequency of HLA-DRB1 * 0701 in the chronic hepatitis B (CHB) group was markedly higher than that in the normal control group (17.8% vs 7.4%), with significant correlation between them (P < 0.05, A = 1/0.367 approximately 2.725). The allele frequencies of HLA-DRB1 * 0401/0403/0405 and HLA-DRB1 * 1301/1302 in the normal control group (16.2%, 4.4% ) were markedly higher than that in the CHB group (5.1%, 0), with statistical significance (P < 0.05, A = 3.602; P < 0.05). The other alleles between the CHB group and the normal control group are no significant differences.</p><p><b>CONCLUSION</b>HLA-DRB1 * 0701 is closely associated with the susceptibility to familial hepatitis B,and may be the susceptible or linkage gene. HLA-DRB1* 0401/0403/0405 and HLA-DRB1 * 1301/1302,in inverse proportion to the susceptibility to familial hepatitis B, may be the resistant gene. They may regulate the outcome of familial HBV infection in a patient.</p>

<p><b>OBJECTIVE</b>To investigate the polymorphism of HLA-A, -B, -DRB1 genes in Han population in Shanxi of China.</p><p><b>METHODS</b>Polymerase chain reaction-sequence specific primers (PCR-SSP) technique was used to identify the polymorphism of HLA-A, -B, -DRB1 genes of 7440 healthy and unrelated individuals of Han population in Shanxi, and the gene frequency distribution of HLA-A, -B, -DRB1 genes in population was compared with the results from other populations.</p><p><b>RESULTS</b>Eighteen HLA-A, forty HLA-B and thirteen HLA-DRB1 alleles were found. The frequencies of A*02, A*24, A*11, A*01, A*03, B*13, B*51, B*15, B*40, B*35, DRB1*15, DR*09, DR*12, DR*04, DR*07 alleles in Hans of Shanxi were significantly higher and displayed distinctive distribution profiles when compared with those of Caucasian and Afro-American.</p><p><b>CONCLUSION</b>The HLA-A,-B,-DRB1 distribution in Shanxi Han population shares some genetic characteristics with other Han populations in northern part of China, but it exhibits its own characteristics.</p>
