BACKGROUND:Previous studies designed and made titanium metal rubber cervical disc prosthesis, and performed feasible studies on its effect on movement and stress distribution by replicating intervertebral discs. OBJECTIVE:To further observe the changes in the stability of goat cervical vertebra after metal rubber cervical disc replacement. METHODS:Nine goats were randomly divided into experimental group (n=6) and normal control group (n=3). Goats in the experimental group received metal rubber cervical disc replacement at C4/5segment. Goats in the normal control group did not receive any treatment. Radiographic data at anteroposterior and lateral position, hyperextension and excessive flexion were taken to measure intervertebral height, range of motion and intervertebral angle at C4/5 segment before operation, immediately, 4, 8, 12 weeks after operation. Subsequently, slicing and embedding of hard tissue at surgical segment, picric acid-acid fuchsin staining and scanning electron microscopy were conducted.RESULTS AND CONCLUSION:No significant difference in the intervertebral height and spinal range of motion at C4/5 segment at different time points was detected between postoperative results in the experimental group and preoperative results in the experimental group, normal control group. The intervertebral height at C4/5 segment was higher immediately, 4 and 8 weeks after surgery than preoperative result in the experimental group (P < 0.05). No significant difference in intervertebral angle at C4/5 segment was detectable between 4, 8 and 12 weeks postoperatively in the experimental group and normal control group (P < 0.05). At 4 weeks after surgery, bone did not contact with the edge of the prosthesis in the experimental group. At 8 weeks, the gap between bone and the prosthesis became smal, and some new bone attached to the edge of the prosthesis. At 12 weeks, a few osteoblasts were observed on the surface of the prosthesis. New osteogenic tissue grew into the prosthesis. Results suggested that metal rubber cervical disc replacement in the intervertebral space could maintain intervertebral height and range of motion in a short period, and tightly bind to the vertebral body.

OBJECTIVE: To observe the effects of warming spleen and stomach for dispersing phlegm recipe (Wenzhong Xiaotan Recipe, WZXTR), a compound traditional Chinese herbal medicine, on expression of interleukin-8 (IL-8) in S(180) tumor tissue in mice, and to explore the effectiveness and its mechanism. METHODS: Fifty mice were randomly divided into five groups: untreated group, cold water-treated group, cold water and WZXTR-treated group, cold water and dispersing phlegm and eliminating stagnation recipe (Xiaotan Sanjie Recipe, XTSJR, another compound traditional Chinese herbal medicine) treated group, cold water and tegafur-treated group. Mice in the latter 4 groups were fed 0-4 degrees centigrade cold distilled water 10 ml/(kg x d) one week before tumor inoculation for 3 weeks. Mice in the 5 groups were inoculated neoplastic cells which were diluted 2 x 10(7)/ml with normal saline in the right armpit at the second week. Forty-eight hours later, the mice were given drugs intragastrically (WZXTR, XTSJR and tegafur, respectively). The mice were continually intervened by cold water in the morning and given drugs in the afternoon. Mice in the cold water-treated group were given normal saline, and nothing was given in untreated group. Morphology appearance and changes of rectal temperature were observed, and the tumor weight and volume were measured and inhibitory rate was calculated 22 days after tumor inoculation. IL-8 was detected by avidin-biotin system-enzyme-labeled immunosorbent assay (ABC-ELISA) and real-time reverse polymerase chain reaction (real-time PCR). RESULTS: The content of IL-8 in tumor tissue of the untreated group was significantly higher than that of the other groups (P<0.01), and that of the cold water-treated group was higher than that of the cold water and WZXTR-treated group (P<0.01) and the cold water and XTSJR-treated group (P<0.05), respectively. The gray scale value of cDNA amplification strap was descent more evidently in both the cold water and WZXTR-treated group and the cold water and XTSJR-treated group as compared with that of the cold water-treated group and the untreated group (P<0.05). CONCLUSION: WZXTR can restrain tumor growth, and the mechanism may be that it can degrade the expression of IL-8 in S180 tumor.

BACKGROUND:Previously deep burn wound or skin defects are generaly repaired with skin grafting or flap of skin grafting. Obvious scar hyperplasia usualy appears after operation, which requires multiple surgeries. Meanwhile, patients have to suffer from great pain and bear high cost. OBJECTIVE: To observe the clinical effects on deep wounds by continuous traction of self-designed skin-stretching device (patent No. ZL 2012 2 0022443.7). METHODS: Thirty patients with deep burn wound, skin defect or funicular scar were enroled, including 22 males and 8 females, aged 18-49 years, and randomly divided into two groups. Skin-stretching device was adopted for skin traction treatment. Twenty cases underwent skin traction from 1 kg puling force to 5 kg, with an increase of 1 kg per 2 days, 6 hours a day for 10 days. Blood flow at the beginning, 1, 5, 10, 15, 20, 30, 60 minutes of the skin traction, and the changes of wound edge skin as wel as histological changes of the skin were observed. Of the remaining 10 cases, 2, 6, and 2 cases underwent skin traction of 2, 4, 7 kg, respectively. Blood flow and skin changes were also observed to find out the most suitable and safe force. RESULTS AND CONLUSION:Al the 30 cases achieved primary healing without necrosis of skin, infection or peripheral circulatory disorders, and the appearance and function recovered wel. The healing time was 8-24 days. The skin-stretching device was most safe under 4 kg puling force, by which, there was neither blood circulation obstacle nor tear of skin. After traction, the skin blood flow and the number of cels increased, especialy the epithelial basal cels. The colagen fibers became thicker and denser, and the elastic fibers regenerated significantly; the fibroblasts and capillary density increased. It has been proved that we can better close the wound and reduce scar formation effectively with the self-designed skin-stretching device for skin traction.
