Objective To discuss the influence of Recipe Wenzhongxiaotan to S180 bearing cancer mouse interfered by cold pathogenic factor and study correlation factor index. Methods To treat S180 bearing cancer mouse by interfere in ice water with Recipe Wenzhongxiaotan, with the control of Recipe Xiaotansanjie group and chemotherapy group, the change of morphology and rectal temperature in mouse, growth velocity and volume in tumor after treatment with Recipe Wenzhongxiaotan were observed, and TXB2 in plasma of mouse was detected by RIA. Results It showed late and short in chilly morphology and rectal temperature amplitude small than other groups in Recipe Wenzhongxiaotan group. The rate to restrain tumor growth was 86.69%, 75.29%, 87.55% in Recipe Wenzhongxiaotan group, Recipe Xiaotansanjie group and chemotherapy group (FT-207), respectively. TXB2 was near in Recipe Xiaotansanjie group and chemotherapy group and the difference was significant compared cold model group (P 0.05) in Recipe Wenzhongxiaotan. Conclusions It may be restrain tumor growth which S180 tumor-bearing mice interfered by cold pathogenic factor and degrade TXB2 in Recipe Wenzhongxiaotan, the rate to restrain tumor growth was near to FT-207 and Recipe Xiaotansanjie.

AIM: To compare the ligustilide content in Siwu Decoction and its ingredient herb. METHODS: To extract with SFE-CO 2 and to determine ligustilide with HPLC. RESULTS: Of the content of ligustilide, the highest in single herb, next in the mixture of Angelicae Sinensis Radix and Lignstic Rhizoma, the lowest in Siwu Decoction. CONCLUSION: When Angelicane Sinensis Radix and Lignstic Rhizoma were in compound preparation, the content of ligustilide became lower obviously.

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: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 evaluate the effect of carbon fiber couch on dose distribution of radiotherapy planning and verification pass rate.Methods Establishing the carbon fiber treatment couch model in Pinnacle8.0m Treatment Planning system (TPS),and then this model was used to correct dose calculations of oblique fields in the treatment plans of 10 cases of nasopharyngeal carcinoma,10 cases of breast cancer and 10 cases of lung cancer and evaluate the effect of carbon fiber couch on the whole dose distribution of the plans.Then these plans were measured by three-dimensional dose verification equipment Delta4 to confirm the improvement extent of Gamma pass rate after considering the carbon fiber treatment couch.Results For the majority of plans,when the carbon fiber couch was taken into consideration,the target doses was significantly reduced (4772 cGy-7266 cGy vs.4859 cGy-7347 cGy,P=0.000-0.002) and the relative deviation of D95 was 1% to 3%.Measurement results of Delta4 showed that Gamma pass rate (3 mm/3% criteria) increased in all plans (96.4%-98.8% vs.93.4%-97.3%,P =0.000),some of that were up to 5 percentage when the couch model was applied.Conclusions Target doses will be overestimated if the treatment couch is ignored in TPS measurement.,However it should arouse enough attention when the disease with smaller doses corresponding gradient.
