3Y-chromosome evidence for no independent origin of modern human in China显示文摘East Asia is one of the few regions in the world where a large number of human fossils have been unearthed. The continuity of hominid fossils in East Asia, particularly in China has been presented as strong evidence supporting an independent origin of modern humans in this area. To search for such evidence of a possible independent origin of modern humans in China, a total of 9988 male individuals were sampled across China. Three Y-chromosome biallelic markers (M89, M130 and YAP), which were located at the non-re-combinant region of Y-chromosome, were typed among the samples. Our result showed that all the individuals carry a mutation at one of the three loci. The three mutations (M89T, M130T, YAP+) coalesce to another mutation (M168T), which was originally derived from Africa about 31000 to 79000 years ago. In other words, all Y-chromosome samples from China, with no exception, were originally derived from a lineage of African origin. Hence, we conclude that even a very minor contribution of in situ hominid origin in China cannot be supported by the Y-chromosome evidence.KE Yuehai SU Bing LI Hongyu CHEN Lifeng QI Chunjian GUO Xinjun HUANG Wei JIN Jianzhong LU Daru JIN Li 2001Chinese Science Bulletin2001,46,11:7
4Linearly time-varying channel estimation and training power allocation for OFDM/MIMO systems using superimposed training显示文摘We address the problem of estimating the linearly time-varying (LTV) channel of orthogonal frequency division multiplexing (OFDM)/multiple-input multiple-output (MIMO) systems using superimposed training (ST).The LTV channel is modeled by truncated discrete Fourier bases.Based on this model,a two-step approach is adopted to estimate the LTV channel over multiple OFDM symbols.We also present performance analysis of the channel estimation and derive a closed-form expression for the channel estimation variances.It is shown that the estimation variances,unlike that of the conventional ST-based schemes,approach to a fixed lower-bound as the training length increases,which is directly proportional to information-pilot power ratios.For wireless communication systems with a limited transmission power,we optimize the ST power allocation by maximizing the lower bound of the average channel capacity.Simulation results show that the proposed approach outperforms the frequency-division multiplexed training schemes.ZHANG Han DAI XianHua Pan DaRu 2011Science China(Information Sciences)2011,54,7:3
5Effects of CIITA antisense RNA on the expression of HLA class Ⅱ molecules显示文摘To study the effect of the major histocompatibility complex class Ⅱ (MHC Ⅱ ) transactivator (CIITA) antisense RNA on the expression of the human leukemia (HLA) class Ⅱ molecules, 5’ end cDNA sequence of CIITA gene was cloned, and antisense RNA expression vector pcDNA-Ⅱ was constructed. HeLa cells transfected with pcDNA-Ⅱ and pcDNA3 were induced by IFN-γ for 3 d. The expression of HLA class Ⅱ molecules on HeLa/pcDNA-Ⅱ cells was significantly decreased, while it has no effect on the expression of HLA class Ⅰ molecules. This result suggests that the CIITA antisense RNA can inhibit the expression of HLA class Ⅱ molecules in HeLa cells. It also implies a promising approach to generate immune tolerance in qraft transplantation.ZHOU Caihong, LU Daru, ZHU Qiquan, QIU Xinfang & XUE JinglunInstitute of Genetics, Fudan University, Shanghai 200433, China 2000Chinese Science Bulletin2000,45,22:2
6Efficient transfer and expression of human clotting factor IX cDNA in neonatal hemophilia B mice mediated by VSV-G pseudotyped retrovi-rus显示文摘The feasibility of in vivo gene therapy for hemophilia B by VSV-G pseudotyped retroviral vector was introduced. The novel packaging cell line 293GPG was used to produce VSV-G/G1NaBAIX pseudotyped virus with the highest liters up to 8.5×108cfu .mL-1. In contrast to the conventional retrovirus, VSV-G pseudotyped virus was more resistant to inactivation by serum complements (P<0.001). Our results also demonstrated that VSV-G pseudotyped virus was more stable in neonatal mice serum than in adult mice serum (P<0.01). After intraperitoneal injection of different doses of virus, hFIX antigen was detected and lasted for more than 120 d, the highest level reached (72.5+6.1) ng- mL11. Moreover, the functional activity was improved to some extent in all hFIX-treated mice, the most remarkable improvement was observed in the mice treated with higher dose of virus whose clotting activity increased to (3.4±1.5)% and APTT (activated partial thromboplastin time) reduced to (43.2±7.2) s.

7Expression of biologically active human clotting factor Ⅸ(hFⅨ) in the mammary gland of transgenic mice显示文摘The DNA of human factor Ⅸ (hFⅨ) gene vector pMCⅨm, which had been proven to be able to express in in vitro and living cells, was introduced into 586 zygotes of Kunming White Mice by positive pressure microinjection technique with manual operation. The 499 survival embryos after microinjection were then transferred into pseudopregnant recipient mice and 216 F 0 pups were born. The analysis of PCR and Southern blot hybridization showed that, of the 216, 6 (2 females and 4 males) were integrated with foreign DNA in their genomes, giving an integration frequency of 3% (6/216). Two F\-0 female transgenic mice could express hFⅨ protein in their milk and the content was over 100 ng/mL as measured with ELISA. The biological activities of hFⅨ in the milk of two F\-0 mice were 44 67% and 79 43%, respectively.HUANG Ying 1, ZHANG Kezhong 2, HUANG Wenying 1, LU Daru 2, HUANG Ying 1, MA Zhanlu 1, REN Zhaorui 1, QIU Xinfang 2, XUE Jinglun 2, ZENG Yitao 1 and HUANG Shuzhen 1* 1.

17Construction of Regular Rate-Compatible LDPC Convolutional Codes显示文摘In this paper, we propose a new method to derive a family of regular rate-compatible low-density parity-check(RC-LDPC) convolutional codes from RC-LDPC block codes. In the RC-LDPC convolutional family, each extended sub-matrix of each extended code is obtained by choosing specified elements from two fixed matrices HE1K and HE1K, which are derived by modifying the extended matrices HE1 and HE2 of a systematic RC-LDPC block code. The proposed method which is based on graph extension simplifies the design, and prevent the defects caused by the puncturing method. It can be used to generate both regular and irregular RC-LDPC convolutional codes. All resulted codes in the family are systematic which simplify the encoder structure and have maximum encoding memories which ensure the property. Simulation results show the family collectively offer a steady improvement in performance with code compatibility over binary-input additive white Gaussian noise channel(BI-AWGNC).Liwei Mu Chulong Liang Zhiyong Liu Daru Pan 2016China Communications2016,13,8:1
