Malignant tumors still threatens the human's health seriously. Metastasis and recurrence lead to the failure of treatment, and multidrug resistance adds the difficulty of therapy of to malignant tumors. But the mechanism is yet unclear. Nowadays, it is found that there's a small group of cells with selfrenewal and indefinite potency in the tumors, and they are the sources of metastasis and recurrence. This small group of cells is called cancer stem cells. Subsequently, the cancer stem ceils were separated and determined from hematological system tumor and solid tumor respectively. The cognitions for metastasis and recurrence and muhidrug resistance of malignant tumor have changed with proposal and verification of the cancer stem cell theory, which provides a new clue to the treatment of tumor and prevention for the metastasis and recurrence.

BACKGROUND: The metal implant internal fixation exhibits good effect for femoral neck fractures of young patients, but few studies report the metal implant treatment for femoral neck fracture in the aged patients. OBJECTIVE: To compare different implant treatments for osteoporotic hip fractures in senile patients. METHODS: A total of 237 aged patients with osteoporotic hip fracture, aged from 60 to 96 years old, were recruited from the hospital between January 1998 and December 2008. There were 32 cases treated by cannulated screw internal fixation, 23 cases by anatomical plate internal fixation, 41 cases by dynamic hip screw internal fixation, 111 cases by bipolar femoral head replacement, and 30 cases by total hip replacement. Comparison of the incidence of complications and the recovery of hip function were performed in each group. RESULTS AND CONCLUSION: Cannulated screws, anatomical plates, dynamic hip screw internal fixation showed a higher complication rate significantly than bipolar femoral head replacement and total hip arthroplasty (P < 0.01); the good and excellent effect rate in cannulated screw, femoral end plate, and dynamic hip screw fixation was significantly lower than that in bipolar femoral head replacement and total hip arthroplasty (P < 0.001, P < 0.01). The results suggested that artificial joint replacement (bipolar femoral head replacement or total hip replacement) is the optimal choice for aged osteoporotic femoral neck fracture, cannulated screw fixation is suitable for Garden I, dynamic hip screw fixation and proximal femoral anatomical plate fixation fit for intertrochanteric fractures of Jensen-Evans I-Ⅱ; Jensen-Evans Ⅱ-Ⅲ osteoporotic intertrochanteric fractures joint replacement is the ideal choice.

Objective:To clone and express the gene of ovomucoid,which is the main allevgen in egg white.Methods:Using total RNA of chicken oviduct as template,the gene of ovomucoid was amplified by RT-PCR.The homology was analyzed by comparision with the sequence in GeneBank.Subsequently,the PCR product of the ovomucoid gene was cloned into prokaryotic expressing vector pET-28a and was expressed by the challenge of IPTG.Results:The whole gene of ovomucoid,one of the main allergens in egg white,was successfully cloned.The cloned ORF sequence contains 633 bp,including stop codon,encods for 210 amino acids.Sequence analysis shows that the ovomucoid gene displays 99% nucleotide identities with the published sequences.The molecule weight of ovomucoid protein obtained was 21 kD.By the challenge of IPTG,SDS-PAGE analysis showed that the ovomucoid gene was overexpressed in E.coli BL21(DE3).Conclusion:The gene of ovomucoid is cloned and overexpressed in E.coli BL21(DE3).This study will be the basis for the further research.

Four cell lines (C6, H6, B6, 2H6) of hybrids secreting monoclonal antibodies (McAb) against erythrocytic stage of Plasmodium falciparum Fcc7801/HN were established by fusing SP2/0 myeloma cells with spleen cells of BALB/c mice immuniaed with the preparation of the same malaria parasite and cloning three times. Of these four lines, C6 and B6 showed significant growth-inhibition of P. falciparum in vitro. Both C6 and B6 McAb recognized 71 kD antigen of P. falciparum by Western Blotting. The results indicate that the 71 kD antigen is of immune protection The four McAb showed cross immunofluorescence reactivity with P. falcipanum Fcc-1/HN, Fcc7802/HN, Fcc8703/JS and P. berghei. P. cynomolgi. It indicates that there are common epitopes among these malaria parasites, and that it is important in immunologic research and serodiagnosis of malaria
