Objective: To prepare surface with collagen, so as to increase the histocompatibility of deantigenic bovine cancellous bone. Methods: Bovine cancellous bone was degreased and macerated by H 2O 2 and decalcified with 0.3 mol/L HCl to form scaffold, surface of which was treaed with collagen, then cultured rabbit osteoblasts were seeded into the scaffold and cultured in vitro . 4, 10, and 21 days later, the cells on the composite materials were observed under sanning election microscope. Results: On day 4, the cells grew in the surface of the scaffold; on day 21, the cells grow into the pores and on all of the surace of the scaffold.Conclusion: Deantigenic bovine cancellous bone with surfaces treated by collagen is histocompatable with rabbit osteoblasts.

BACKGROUND: Bone defect repair is a difficulty in orthopedic field all the time, researches on the tissue engineered bone tissue have provided completely new thoughts and methods for bone defect repair, and it is an important link to detect the biocompatibility of the biomaterials.OBJECTIVE: To investigate the biocompatibility of PCL with bone marrow stromal cells (BMSCs).DESIGN: A controlled observation.SETTING: Department of Orthopaedics, the First Affiliated Hospital of Xinjiang Medical University.MATERIALS: The experiments were carried out in the orthopedic laboratory of the First Affiliated Hospital of Xinjiang Medical University. Healthy 4 to 8-week-old New Zealand rabbits of about 2 kg were used.METHODS: ① Bone marrow was extracted from bilateral femurs of the rabbits, then mixed into 10 mL RPMI1640 complete medium, and then entered the passage culture. ② The cells were inoculated and then divided into PCL group and control group, the cells were only inoculated in the control group, and the BMSCs were co-cultured with PCL in vitro in the PCL group. The morphological observed, cell proliferation, protein content and enzymological determinations were conducted.MAIN OUTCOME MEASURES: The growth and the adhesion of BMSCs on PCL biomaterials were mainly observed.RESULTS: In the control group, most of the BMSCs changed to the shape of fusiform or multi-angles. In the PCL group, the BMSCs could adhere and proliferate on PCL, and the growth and function were not affected, PCL also played a certain role in promoting the cell proliferation.CONCLUSION: PCL possess satisfactory biocompatibility, and it is possible to be used as the carrier of BMSCs in tissue engineering.

Objective To investigate clinical outcomes and side effects of 103Pd seed brachytherapy for malignant tumors. Methods Twenty patients with residual or recurrent unresectable malignancies were treated with 103Pd seed implantation under the guidance of ultrasonigraphy or CT scans. Three patients were given a local anesthesia and 17 patients, general anesthesia. The match peripheral doses ranged from 97.3 Gy to 182.78 Gy (mean, 123 Gy). The activity of each seed ranged from 1.4 mCi to 1.8 mCi. The planning target volume (PTV) included a 1 cm isotropic expansion margin around the clinical target volume (CTV). The seeds were retrogradely placed with a Mick applicator. External beam radiation was required 3～4 weeks after seed implantation in 6 patients, with a total dose of 45～50 Gy and 2 Gy each fraction. All of the patients received CT scanning after implantation for quality evaluation and underwent routine chest X-ray examination at 24～48 hours for seed observation. Results A complete response was achieved in 5 patients and a partial response in 12 patients. Two patients were assessed as having stable disease. In 1 patient with prostatic cancer, the serum PSA level was decreased significantly. The local control rate was 90% (18/20). The 20 patients were followed for 2～25 months (median,11 months).Two patients were lost to follow-up at 6 and 12 months after operation, respectively. Twelve patients died and 6 patients survived.No severe complications were recorded postoperatively. Conclusions 103Pd brachytherapy for malignant tumors gives a high local control rate and satisfactory reliability.

Objective To study the clinical application oflaparoscopic-assisted operation to colorectal neoplasms. Methods 28 cases of colorectal neoplasms underwent laparoscopic surgery from July 1997 to November 2000. The mean age was 65.3 years old(33～89)years.3 cases underwent right hemicolectomy.1 case of sigmoid colon adenoma was given partial colectomy. Sigmoid-rectal anterior resection was conducted in 21 cases. 3 cases underwent abdominal peritonieal resection. Results 5 cases were converted to open laparotomy.The mean operative time was 178(150～300)min for 23 cases given laparoscopic surgery with 135(30～1000)ml of average intraoperative bleeding. Neither postoperative complications nor intraoperative deaths occurred.1 case of low portion rectal cancer showed abdominal metastasis 12 months after surgery.Neither port site nor incision metastasis happened. Conclusions Laparoscopic assisted surgery has the advantages of less surgical trauma,less gastrointestinal interference and quicker recovery. Under the circumstances of radical resection and selected candidate,laparoscopic assisted surgery can be applied to colorectal neoplasms.

Objective To study on the diagnosis methodology of breast cancer using integrated analysis of proteomics and metabonomics approach.Methods The serum samples from the 14 breast cancer patients and 7 healthy people were analyzed by two-dimensional electrophoresis in order, to find differential expressed proteins. On the other hand, an HPLC-based urinary metabonomics profiling was employed to pick out chemical patterns between breast cancer patients and healthy people.Results Glutathione S-transferase M5 was found highly expressed in the breast cancer patients′serum.The concentration pattern of S-Adenosylmethionine, Orotidine, 1-Methyladenosine and N2-Methylguanosine in patients′ urine were peculiarly different from that in the healthy people.Conclusion There are peculiar chemical pattern differentiae between the body fluid of breast cancer patients and the body fluid of healthy people. Synthetic study of cancer proteomics and metabonomics can contribute not only to prognosis of cancer but also to the pathogenesis of cancer.

BACKGROUND:An appropriate biomaterial can be directly combined with autologous or al ogeneic skin cel s to construct tissue-engineered skin, which can accelerate skin repair after transplantation onto the skin wounds. It is a good idea to solve the deficiency in skin sources. OBJECTIVE:To study the biological characteristics of the complex with bone marrow mesenchymal stem cel s and to investigate the application of this complex in skin defect repair. METHODS:Twenty-eight Sprague-Dawley rats, SPF grade, were randomized into two groups (n=14 per group). By adjustment of temperature, time, pressure and area of NC perm instrument, scald models were made in rats. Rats in the treatment group were given the repair using composite bone marrow mesenchymal stem cel s, while those in the control group were given vaseline gauze repair. Repair effects were compared between two groups. RESULTS AND CONCLUSION:(1) After 72 hours of culture, the composite bone marrow mesenchymal stem cel s smal with round shape distributed dispersedly. After 5 days of culture, the cel s began to stretch and the cel morphology became unstable. After three passages, the cel morphology became stable. The results of antigen identification showed the expression of CD44 and CD29 but the low expression of CD45 and CD34 in bone marrow mesenchymal stem cel s. (2) Twenty-eight days after repair, there was no obvious scar on the wound surface of the treatment group, but a little shrinkage and obvious scar stil existed in the control group. Moreover, in the control group, the epidermal layer of the skin was relatively thick, and the connection between the basal layer and the dermis was unsatisfactory. In the treatment group, obvious epidermal cel stratification, neat arrangement, and tight connection between the epidermis and dermis were observed. In summary, bone marrow mesenchymal stem cel s are a special class of cel s that have pluripotent ability and are more readily available. These cel s are the preferred target cel s for skin defect repair to promote early healing of the skin and improve blood circulation defect site, which are confirmed to have high clinical value.
