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.

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.

This article analyzed the ethical situation in hospitals. The author pointed out the defect of confidence between doctor and patient is the primary cause that leaded to the deterioration of doctor-patient relation, and the retardation of medical service management is the important factor that affected the confidence construction. According to all this above, the author proposed the suggestion of strengthening the understanding and communication between doctor and patient, transforming the medical service concept, enhancing the medical service quality, completing the supervising system, increasing the hospital ability of realizing medical service defect and improving the five thoughts of follow up confidence system to direct the hospital confidence ethical construction.

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.

Background Clinical researches showed that antimicrobial-resistance of bacterium is gradually serious.It is very important to master pathogen distribution and antimicrobial susceptibility after eye surgery.Objective This study was to investigate the distribution and drug sensitivity of pathogenic bacteria from ocular operative infection in 3-year duration to provide a reference for reasonable selection of antibiotics.Methods Sixtyfive positive specimens were obtained from 65 patients due to postoperative infection in Department of Ophthalmology of Shenzhou Hospital and Shengjing Hospital from 2009 January through 2011 December.The pathogenic bacteria were isolated and then the drug sensitivity test of conventional antibiotics was performed.Results Among the 65 ophthalmic specimens,35 strains of Gram-positive bacteria were isolated with the constituent ratio 53.8％,and 15 strains of Gram-negative bacteria accounted for 23.1％.Fungus was found in 15 cases with the constituent ratio 23.1％.Staphylococcus epidermidis accounted for 42.9％ in Gram-positive bacteria,and Pseudomonas aeruginosa accounted for 33.3％ in Gram-negative bacteria.Aspergillus was the main component of fungus,which accounted for 60.0％ of the proportion 3 strains of methicillin-resistant Staphylococcus aureus (MRSA) in 8 strains of Staphylococcus aureus,but no vancomycin-resistant Enterococcus (VRE) and vancomycin-resistant Staphylococcus (VRS) were seen.The in vitro drug sensitivity test showed that the main Gram-positive bacteria,Staphylococcus epidermidis and Staphylococcus aureus,were sensitive to linezolid,vancomycin,levofloxacin and ciprofloxacin with the sensitive rates ＞50.0％,and these bacteria were lowly sensitive to penicillin and erythromycin with the sensitive rates ≤30.0％.Pseudomonas aeruginosa appeared to be the main Gram-negative bacteria,showing a sensitive rate ≥ 80.0％ to tobramycin,amikacin,ceftazidime,cefepime,cefoperazone/sulbactam,piperacillin/tazobactam,imipenem and meropenem.Conclusions Staphylococcus epidermidis,Staphylococcus aureus,Pseudomonas aeruginosa and Aspergillus are primary pathogens in ocular infection after operation.Antibiotics such as penicillin,erythromycin,levofloxacin,cefotaxime seem to be relatively high resistant to eye infection.To choose sensitive antibiotics timely and reasonably is a key to the prevention and control of ocular infection after operation.
