The SRY gene from buffalo (Bubalus bubalis) genome was amplified by the polymerase chain reaction ( PCR) with primers based on the sequence of Hostein SRY gene. The amplified fragment was 2005 bp include 5UTR ( 1 - 504bp) and 3'UTR(1196 - 2005bp). And the amplified fragment was cloned and sequenced. Sequence analysis showed that the coding region of SRY gene (505 - 1195bp) from buffalo was highly homologous with those of other bovine counterpart genes (96% homology) , especially in the HMG box region (99%homology). It was found that there were only signal on male buffalo genome on Southern blot,which indicate SRY gene are highly conservative on evolves.

The crude toxin was extracted from hypha and culture solution of Phyllosticta commelimecola through three different polarity solvent: benzinum, puncificatum ethyl acetate and chloroform. The result indicated that the toxin secreted by Phyllosticta commelimecola not only was in hypha but also in culture solution and the extracting effect of ethyl acetate was the best. The soybean median and PSK media can be respectively used as solid and liquid culture media to produce toxin and grow mycelium. The optimal cultural conditions for producing toxin were temperature 32℃,cultured period 14d, cultured ways shaking of 150r/min.

Objective To explore the prevalence rates of disabilities among the ethnic minority people in China. Methods Utilizing stratified, multiphase, and cluster probability sampling design, 2 526 145 persons were investigated and screened by trained interviewers,including 297 761 persons with ethnic minority backgrounds. Respondents scoring positive for potential problems were referred to physician for further diagnosis on disability and on scale measurement.Results The overall prevalence rate of disability for both ethnic minority and Han population were 6.24% (95%CI:6.16%-6.51% ) and 6.41% (95% CI: 6.38%-6.51% ) respectively. The total aggregate age-adjusted prevalence rate of disability was 7.31% for persons with ethnic minority. The prevalence rate of disabilities in male was significantly higher than that in females (7.31% vs. 6.75% ). The ranking of prevalence rates on different type of disabilities were: physical disability 1.90% (95%CI:1.89%-1.91%), hearing disability 1.34%(95%CI: 1.33%-1.35%), multiple disability 1.14%(95%CI:1.13%-1.15% ), vision disability 0.99% (95%CI: 0.97%-1.01% ), psychiatric disability 0.38%(95%CI:0.37%-0.40% ), intellectual disability 0.38% (0.37%-0.39%) and speech disability 0.12% (0.11%-0.13% ). Cerebral Palsy, genetic diseases, tympanitis, cerebral disease and mental retardation (not including unknown items) were the major causes for disabled children with ethnicity background.Degenerated diseases, including osteoarthropathy, cerebrovascular disease, elderly-related deafness or cataract were most important causes for ethnic minority persons aged 60 or over. Injury, including traffic accident was important disabled-related factor for persons with minority ethnicity aged 15-59.The main causes and ranking of causes for ethnical minority were similar with that for Han population.Conclusion The prevalence rate of disability for ethnic minority persons was significantly higher than that for Han population in China. Prevention for different types of disability should be provided accordingly to persons with ethnic minority, in different age groups.
