Combination of CTLA4-FasL gene transfer and allogeneic bone marrow transplantation led to durable macrochimerism and donor-specific tolerance in mouse model

2.06 10th International Conference on Communication Technology（ICCT 2.06）

作者： Souyin liu Wenwu Xie Jinjing Zhan Fan li {2. of Electronic and Information Engineering huazhong normal university Wuhan 430079 China.

In this paper, in order to reduce the complexity of the receiver, the receive antenna selection （AS） is applied to the systems with the differential space-time modulation （DSTM） scheme based on Quasi-Orthogonal Space-Time Block Coding （QO-STBC）, in which four transmit-antennas and multiple receive-antennas are equipped at the transmitter and receiver, respectively. Then a novel selection rule for this system is derived based on the maximum a posteriori probability （MAP） criterion. The corresponding simulations are carried out to prove the performance of our proposed scheme with our derived selection rule. Results show that: （1） our proposed scheme combined with our derived selection rule can obtain better performance compared with the single receive antenna systems;（2. it has the same diversity and only a little loss in coding gain but much lower complexity compared with the multiple receive-antennas systems without receive antenna selection.

Mixed hemopoietic chimerism is capable of inducing donor specific tolerance, thus eliminating the chronic immunosuppressive therapy following organ trans- plantation. As yet no safe and effective tolerance protocol is available for clinical implementation. Here we describe an alternative nonmyeloablative based strategy of using a single injection of recombination adenovirus vector encoding CTLA4-FasL fusing gene and donor bone marrow cells to promote durable mixed macrochimerism (>2.% on 140 d). Chimeras exhibited robust donor-specific tolerance, as evi- denced by acceptance of fully allogeneic skin grafts (the mean survival time (MST)>2.0 d) and rejection of third- party skin grafts in a {2. manner (MSTlitate the bone marrow engraftment, while both HTLp and CTLp remained at low level only in recipient mice with mixed chimerism on day 140 after transplantation, demon- strating that long-term skin grafts tolerance was associated with stable mixed chimerism, and central deletion of donor specific T cell may be the main mechanism for tolerance maintenance.

Journal of Reproduction and Contraception 2011年第1期22卷 29-36页

作者： li-xia ZHU Xin-ling REN li WU Juan HU Yu-feng li Han-wang ZHANG Qing-song XI Reproductive Medicine Center Tongii Hospital Tongji Medical College Huazhong University of Science and Technology Wuhan 430030 China department of Oncology Tongji Hospital Tongji Medical College Huazhong University of Science and Technology Wuhan 430030 China

Objective To evaluate the application value of rescue ICSI in fertilization failure after conventional IVF and choose the best rescue window before oocyte aging according to the results of rescue ICSI performed in different time. Methods The data of 93 IVF cycles were analyzed retrospectively. Rescue ICSI was performed in these cycles after conventional IVF failure. Because of the different rescue time, these cycles were divided into two groups： early rescue group （group A, 77 cycles, rescue ICSI performed 4-8 h after conventional IVF） and late rescue group （group B, 16 cycles, rescue ICSI performed 2.-2. h after conventional IVF）. Results There were no statistically significant differences in age of female, duration of infertility, number of oocytes retrieved every cycle. The normal fertilization rate, pregnancy rate and implantation rate were decreased in group B compared with those in group A （P〈0.05）. In group A, the normal fertilization rate of rescue ICSI performed 4-6 h after conventional IVF （group A1） was increased compared with that of rescue ICSI performed 6-8 h （including 6 h） after conventional IVF （group A2.（66.5% vs 55.9%）（P〈0.05）; while the abnormal fertilization rate in group A1 was decreased compared with group A2.（9.0% vs 14.4%）（P〈0.05）. Clinical pregnancy rate was slight higher in group A1 than in group A2. though this failed to be significantly different. Conclusion Rescue ICSI is effective if fertilization was failure after conventional IVF, the most important thing is to choose the reasonable rescue window before oocyte aging when ICSI is performed.

Fifty six SD rats were randomly divided into the normal control group and the operation group. The operating group was subdivided into six groups on the basis of killing time (the 12.h h, the first day, 3rd day, first week, 2.d week and 4th week) after vagotomy (VG). The pancreatic tissues were taken for HE and Feulgen staining. The DNA content of pancreatic exocrine cells was determined by a domestically fabricated computer image analyzing system. In the control group, on the first day or in the first week after VG, the pancreatic samples were taken for transmission electron microscopic examination. The DNA content of pancreatic exocrinal cells was decreased from 1 to 3 days after VG. The secretion was found to be in inhibitory state and One week later, it gradually restored. The results indicated that the proliferation and the function of the SD rat's pancreatic exocrinal cells were prohibited at initial stage after VG, which might be concerned, at least in part, with dominance and nutrition of vagus.
