Objective:To explore of the medical and economic coordination development in provincial regions of China and its spatial-temporal evolution so as to provide new thought for researching the relationship between medical and economic growth.Methods:Based on physics concept and retated research,coordination development model was built to analyze the medical and economic coordination development in provincial regions of China.The exploratory spatial data analysis was used to analyze its spatial-temporal evolution.Results:There were certain progresses on medical and economic coordination development in provincial regions of China.Transition class regions were in the majority,while coordinated and unbalanced class regions were in the minority.The medical and economic coordination development degrees were agglomerated spatially.Both high and low values of medical and economic coordination development degrees are agglomerated obviously.Hot and sub-hot regions were mainly distributed in eastern and central China,while cold and sub-cold regions were mainly distributed in western China.Conclusion:Coordination development model could be applied for researching the medical and economic coordination development in provincial regions of China which provided new basis for further research on the relationship between medical and economic growth.

A protein designated as Flammulina Velutipes (FV) protein was isolated from the cultured mycelium of FV and purified to homogeneity by CM cellulose CM 52 and gel filtration chromatography. The molecular weight of FV protein were found to be 1.75?10~4u with pI 4.3. Amino acid analysis of FV protein indicated the presence of 14 kinds of amino acids, especially rich in Glu, Asp and Thr.Potent inhibitory effect of FV protein on thrombus formation, in the blood was observed in vitro when rats were given intravenously. The length of thrombus was shortened and the dry weight of the thrombus decreased significantly at the dose of 7.5?10~(-7) mol/kg. Thrombus formation was completely inhibited at the dose of 10~()-8 mol/kg. The IC_(50) was found to be 4.4?10~(-7) mol/kg. FV protein was shown to inhibit collegen induced aggregation of rat platelets both in vitro and in vivo. Its concentration for complete inhibition in vitro was 7.5?10~(-5) mol/L. The IC_(50) was found to be 4?10~(-5)mol/ L. However, FV protein dose of 1.25?10~(-5) mol/kg was required for 60% inhibition in vivo

ObjectiveTo investigate the effectiveness and toxicity of CyberKnife in the treatment of lung metastases.MethodsTreatment details and outcomes were reviewed for 93 targets of 48 histologically verified patients treated by CyberKnife at the CyberKnife Center of Tianjin between September 2006 and June 2010.The median tumor volume was 6.0(0.2 - 135.2) cm3,the median biological equivalent dose was 140.8(53 - 180) cGy (α/β =10),the median fraction was 3(1-7) times and the median isodose line was 81％ (71％-91％ ).ResultsThe rate of follow-up is 96％.33 cases were followed up for more than 2years.The effective rate was 90.3％.Two targets of 2 patients locally progressed.The 1-and 2-year local control rates,overall survival (OS) rates and progression-free survival (PFS) rates were 98％ and 98％,83％ and 63％,and 64％ and 37％,respectively.Univariate analyses showed that age older than 60 versus ≤60 years tended to be predictor for PFS ( x2 =3.45,P =0.063 ) ;The PFS of patients who had single lesion was better than patients with multiple lesions ( x2 =4.49,P =0.034 ) ; patients with disease-free interval longer than 18 months had better OS ( x2 =6.50,P =0.011 ).Five patients were reported to experience treatment-related grade 1 radiation pulmonary injury,and one each for subcutaneous fibrosis with pigmentation,grade 2 and grade 3 adverse event.ConclusionsFor patients with lung metastatic lesion,CyberKnife is an effective option with high local control rate and little acute reaction.The long-term outcome and toxicity need further study.

Objective To study the efficacy and toxicity of the cyberknife in the treatment of medically inoperable patients with early stage lung cancer. Methods From September 2006 to July 2007,17 patients with clinical stage Ⅰ a- Ⅰ b lung cancer were treated with cyberknife at Tianjin Cancer Hospital. Of the 11 patients receiving CT guided biopsy, 3 were squamous cell cancer and 8 were adenocarcinoma. Six patients refused intrusive operation and were diagnosed by PET-CT scan. All patients were medically inoperable evaluated by a thoracic surgeon. The PTV = GTV + 3 ～ 5 mm, and the median volume of PTV was 36 cm3 (6-82 cm3 ). The median total prescription dose was 50 Gy(45-60 Gy) at 3-5 fractions. Results The median follow-up time was 7 months (3-11 months). All the patients finished the treatment and were alive by the last follow-up. Slight fatigue was the most common complain. Evaluated by CT scan, 13 were complete response and 4 were partial response. No recurrence, progression or distant metastasis occured. There were 3 patients with grade Ⅰ granulocytopenia,3 grade Ⅰ pneumonitis and 1 grade Ⅱ pneumonitis. Conclusions The cyberknife radiosurgery treatment in early stage lung cancer shows a high rate of local control and minimal toxicity. Long time follow-up is necessary to evaluate the survival data and late toxicity.
