以研究炼焦煤性质与焦炭反应性、反应后强度之间的数学关系为目的，通过胶质体和中间相形成动力学解析导出模型的主要影响因子，以煤的变质程度、煤岩组成、粘结性、灰分及K2O和CaO含量等因素为自变量，由25种工业用煤的炼焦试验，建立出预测模型，并得出壳质组使反应性增大及反应后强度降低；K2O催化作用强于CaO，且两者的催化作用均随煤的变质程度不同而不同等重要结论。

Bone marrow-derived mesenchymal stem cells are capable of chondrogenesis, making them a possible source of cells for injectable cartilage tissue engineering. There exist different ideas on the ability of mesenchymal stem cells's chondrogenesis in monolayer culture. Because of this, the effect of adult rabbit's bone marrow-derived mesenchymal stem cells chondrogenesis in monolayer culture was studied. The mesenchymal stem cells was isolated from adult rabbit's bone marrow and monolayer cultured. TGF-β1, Vit-C and Dexamethasone were used. Immunohistochemistry analyses and histological staining of H-E, Methylaniline blue and Alcian blue were performed to identify the expression of collagen type Ⅱ and cartilage associated matrix. The results showed that the induced cells expressed and produced collagen type Ⅱ and cartilage associated matrix. This suggests that the differentiation of adult rabbit's marrow-derived mesenchymal stem cells into chondrocyte in monolayer culture is feasible and may be induced by TGF-β1, Vit-C and Dexamethasone.

骨髓基质干细胞的软骨分化潜能使其可能成为可注射组织工程化软骨研究的种子细胞，为探讨体外培养的骨髓基质干细胞在平面诱导条件下软骨分化的可行性，我们进行下列实验：获取并体外平面培养成体兔骨髓基质干细胞，应用TGF-β〓、Vit-C和地塞米松对其软骨分化诱导，诱导后的骨髓基质干细胞行细胞爬片组织学和Ⅱ型胶原免疫组化，结果证实，诱导后骨髓基质干细胞可分泌Ⅱ型胶原，组织学染色可见类似于软骨细胞，由此证明体外培养的骨髓基质干细胞在平面诱导条件下可以软骨分化，其软骨诱导因子为TGF-β〓、Vit-C和地塞米松。

Simulate the condition of temperature and energy control in percutanous MWA for HCC to ablate SMMC-7721 cell strain suspension.There were five experiment groups:A.control group,B.45℃10 min group,C.50℃3min group,D.54℃3min group and E.60℃instant group.Detection for apoptosis was performed at 30 minutes and 2 hours after ablation.2.Thirty-two C57 mice were undertaken hypodermic inoculation of Hepal-6 tumor piece at right groin as ablation tumor and at left groin as observation tumor one week later.The mice with double tumors were separated into four groups:A.control group with no treatment,B.MWA group treated with MWA only,C.mDC group treated with MWA and subcutaneous injection of mature dendritic cells sensitized by neoantigen of Hepal-6 cell strain,D.iDC group treated with MWA and peritumoral injection of immature dendritic cells without neoantigen sensitization.

The giant panda-rabbit interspecies reconstructed embryos were constructed by injection of giant panda somatic cells into the perivitelline space of the enucleated oocytes and fused by electrical stimulation, and the reconstructed embryos can develop to hatched blastocyst stage in vitro. We demonstrated that the nuclear genetic materials in reconstructed blastocyst cells were the same as that of giant panda somatic cells by chromosome count and the existence of characteristic chromosome, which was confirmed by microsatellite DNA analysis later In order to determine the fate of mtDNA of giant panda-rabbit reconstructed embryos, we analyzed the cyt b sequence of embryos at 1 -cell stage, 2-cell stage, 4-cell stage, 8 cell stage, morula stage, blastocyst stage, expanded blastocyst stage and hatched blastocyst stage.
