BACKGROUND: In recent years, acel ular human cadaveric dermis has been applied for repairing dermal defects and fil ing soft tissues, but this repair material is expensive and difficult to obtain. OBJECTIVE: To explore the repair effect of tissue-engineered acel ular dermis on wound healing of skin ulcer. METHODS: Sprague-Dawley rats were randomly divided into autologous reticular dermis and acel ular dermis groups. The tissue-engineered acel ular dermis was prepared by hypotonic solution, 2.5 g/L trypsin, 0.5% Triton X-100 and PBS solution, and in the meanwhile, a rat model of skin ulcer was established. Then, autologous skin graft and tissue-engineered acel ular dermis were transplanted into the autologous reticular dermis group and acel ular dermal group, respectively. Subsequently, comparative study about the repair effect and relative mechanism between two groups was performed. RESULTS AND CONCLUSION: The tissue-engineered acel ular dermis showed a white and grainy shape at room temperature. And hematoxylin-eosin staining showed that: the internal structure of tissue-engineered acel ular dermis exhibited a dendritic distribution, and the gap between col agen fiber bundles was relatively large. At 2, 3, 4 and 8 weeks after dermal transplantation, the survival rate of skin graft in the acel ular dermis group was significantly higher than that in the autologous reticular dermis group (P < 0.05). And the wound contraction rate in the acel ular dermis group was significantly higher than that of the autologous reticular dermis group at 3, 4 and 8 weeks after dermal transplantation (P < 0.05). In addition, the average diameter and clearance rate of col agen fibers in the normal skin around wound in the acel ular dermis group were significantly higher than those of autologous reticular dermis group (P < 0.05). To conclude, it is relatively simple to prepare tissue-engineered acel ular dermis under mild conditions, and the prepared tissue-engineered acel ular dermis presents a regular shape. Moreover, this acel ular dermis achieves desired outcomes in repairing dermal defects, which can promote wound healing by reducing the intradermal DNA residual and significantly improving some biomechanical properties in vivo.

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.

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.

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.
