Objective To investigate T cell receptor(TCR)variable β(BV)chain usage at the maternal-fetal interface and explore the relationship between the skewed TCR BV usage and unexplained recurrent spontaneous abortion(BSA).Methods Eighteen cases with unexplained RSA,together with matched 41 women with normal pregnancies in first trimester from Renji Hospital,Shanghai Jiao Tong University were studied.A high-resolution spectrum typing analysis of complementarity-determining region 3 (CDR3)was used to detect and compare the degree and frequency of TCR BV family expression in deciduas between RSA patients and normal controls.Results(1)The expression degree of BV19(0.029±0.031 vs.0.013±0.010,P=0.038)in RSA group showed a higher usage,while BV5.2(0.040±0.035 vs.0.067±0.052,P=0.046)showed a significantly lower usage when compared with normal controls.No significant difference in the expression of the other TCR BV families between RSA and controls were observed(P>0.05).(2),TCR BV2,3,6,and 7 were the four most common BV families in deciduas of patients with RSA and normal controls,whose frequencies were all mors than 50%.In RSA group,higher frequencies of BV15 (33.3%vs.7.3%,P=0.018),BV19(38.9%vs.14.6%,P=0.049)and BV20(33.3%vs.7.3%,P=0.018)were observed;meanuhile lower frequencies of BV4(33.3%vs.65.9%,P=0.026)and BV7 (66.7%vs.92.7%.P=0.018)distributions were observed.The other TCR BV families did not display significantly different freqencies of distribution(P>0.05).Conclusions It is suggested that a significant skewed TCR BV family occurs at the maternal-fetal interface in patients who undergo abortion.The specific skewed usages of TCR BV might be associated with the susceptibility to unexplained pregnancy loss.

As an indispensable part of minority traditional medicine, mineral medicine has used with less dosage and reliable efficacy for the last thousand years. Based on the unearthed relics and medical literatures of past dynasties, the history of Han nationality ap- years, which had been recorded in main literature. But there is less comprehensive report of its usage in the other 55-minority nationality. This article was based on the analysis of ethnic minority literature of thousands of years, and conducted a comprehensive collation and analysis of mineral medicine. It was mostly determined that there was 20 minority groups using mineral medicine, with a total of 163 species (limited our references), and the most used is the Tibetan, accounting for 141. The most serious problems of mineral medicine are that species should be further investigated and researched, and then become the legal commercial medicine, and the classification principles of mineral medicine should be established. Through the traditional processing and experimental studies, the problems of attenuation and detoxification should be solved.
