Setting up a system wherein general practitioners play the role of the “goalkeeper” in the delivery of community health services may guide the rational flow of health resources from the upper to the basic levels, match the allocation of health resources to the demands, improve the effectiveness of health resources allocation, reinforce preventive strategies, and construct a highly efficient and economic health services system. By introducing the role of general practitioners in Britain, Australia and the United States, the paper aims to draw some enlightenment which will contribute to the establishment of such a system in China in the following aspects: ①perfecting the system of national supporting policies; ② making a good analysis of the parties interested; ③improving the makeup of the medical insurance system; ④accepting useful suggestions from relevant learned societies; ⑤ training general practitioners;⑥ establishing standards for the cooperation between general practitioners and specialists.

Most deaths of breast cancer patients may be caused by the development of metastases. The latest research suggest that some miRNAs regulated gene expressions related with breast cancer metastasis at post-transcriptional level, which was closely related to invasion and metastasis of breast cancer. This review mainly dicussed the miRNA involved in regulation of invasion and metastasis of breast cancer and their mo-lecular mechanisms.

Patients who have received coronary artery interventional therapy exhibit visible anxiety and depression, which is closely related to prognosis and life quality. Therefore, for coronary artery stent patients,exception of anticoagulation and antihyperlipedemic drugs, psychological support, cognition therapy and distorted behavior rectification should be applied. The medication of anti-anxiety or depression is of great importance in ameliorate mental state, relieve mental load, as well as enhance prognosis of patients.

Conventional therapy was given to 260 cases of advanced stage of cancer of colon during the period of 1975 - 1988. Radical operation, palliative resection or changing bowel passage were selected according to the condition of the lesions. Post operative chemo -therapy with integrated Chinese and western medicine were given, or with radiotherapy in some of the cases. Results showed that the 5- year survival rates of II, III, IV stages were 80. 5%, 56. 12%, 21. 73% respectively, the mean 5 -year survival rate being 52. 78%, 45 cases with liver metastasis were also treated with integrated medicine with a 5 - year surivial rate of 22. 2%. The above figures of therapeutic effect and survival rates were all superior to that in cases treated by western medicine alone as reported by domestic exponent units.

Objective To explore the re-treatment approach for nonsmall-cell lung cancer(NSCLC)in clinic with therapeutic alliance of cryotherapy and interventional chemotherapy. Methods Sixty two patients with uncontrolled NSCLC after common radiotherapy and(or)chemotherapy were re-treated with therapeutic alliance of cryotherapy and interventional chemotherapy, and their serum tumor markers of NSE, CEA, CY21-1 and the value(I.S%,I.O.D%)of correlative protein in nucleolus region-Ag-NORs were tested before and after the re-treatment. Meanwhile, patients' one year survival and therapeutic effect to NSCLC were recorded during the follow up. Results After the re-treatment, distinguished decline of the serum tumor markers was observed(P

Objective To observe the effects of adenosine and adenosine receptor agonist on the expression of inter?leukin-18 (IL-18) in patients with unstable angina (UAP), and the mechanism of adenosine receptor agonists thereof. Meth?ods Fifteen UAP and 15 healthy volunteers were included in this study. The effects of adenosine and the selective adenos?ine receptor agonists on the expression of IL-18 were measured by enzyme-linked immunosorbent assay (ELISA). Results The lower concentration of adenosine (1-100μmol/L) increased the expression of IL-18 in UAP group;whereas the higher concentration of adenosine (1 mmol/L) inhibited the expression of IL-18. The adenosine A1 receptor agonist and A3 receptor agonist increased the expression of IL-18, while the adenosine A2a receptor agonist inhibited the expression of IL-18. There was no significant effect for A2b receptor agonist on the expression of IL-18. Conclusion The lower concentrations of ade?nosine can enhance the expression of IL-18 through adenosine A1 and A3 receptors in UAP. The higher concentrations of ade?nosine can inhibit the expression of IL-18 through adenosine A2a receptors. Adenosine can promote IL-18 expression in lower concentrations.

Objective To investigate the effect of nursing rescue process on traffic accident aid to orthopedic patients . Methods Sixty patients with bone injuries from traffic accidents during April to December 2013 were set as control group , in which the traditional aid process was used for rescue, and another 60 patients during January to June 2014 as experiment group, in which the nursing aid process was applied. The two groups were compared in terms of rescue time and effectiveness. Result The rescue time in the experiment group was significantly shorter and the first aid effectiveness was also better than those in control group (P<0.01). Conclusion By nursing aid process, the personnel can be optimized to avoid chaos during the rescue and meanwhile the time for rescue is shortened, which can contribute the increased success rate.
