This paper reviews practices and features of health service system planning in some countries, and analyze its implications for China’s system planning. It is an international common practice to perform health service system planning to improve resource allocation efficiency, to meet multilevel demands of medical services, and to control dramatic growth of medical expenditures. Governments and their affiliated departments are the main body to formulate and implement the plans, and different levels of governments have different responsibilities in planning. During the procedure of formulating and implementing plans, collaborative governance network can be utilized to en-courage multi-party stakeholders to participate. The government should play an active role in planning to ensure the equity and accessibility of health services. The authority of planning can be achieved mainly through the comprehen-sive measures in legislation, political regulation, economic incentives, etc. Improved tools and methods based on multidisciplinary theories can be used to improve plan’s scientificity and delicacy. China can learn from international experience in formulating and implementing health service system plans.

Expression of the GST-? in 51 cases of lung cancer was researched by quantitative RT-PCR. The results suggested that the expression of GST-? was significantly higher in lung cancer than in normal tissues adjacent to cancer, and tumoral native resistance might be dominant in tumoral resistance to chemotherapeutic drugs. No relationship was found between GST-? expression and clinicopathological parameters including tumor class, stage and differentiation. The study of GST-? expression is of importance in the evaluation of tumoral resistance to anticancer drugs.

Objective To investigate the influence of synergistic effect of estradiol and testosterone on the level of lipids and coagulation function in mice with hyperlipidemia .Methods We established a maouse model in hyperlipidmia , giving estradiol (1 μg/d), testosterone (7 μg/d) or estradiol combined testosterone (1 μg/d E2 +7Tμg/d), respectively.After 14 weeks, we collected the blood from the mice , separated the serum to detect the lipids level , separated the plasma to test the coagulation function .Result Compared with controls , after high-fat diet , the serum level of total cholesterol ( TC) , triglyceride ( TG) , high density lipoprotein ( HDL) were significantly increased , PT and APTT were shorter ( P<0.05 ).However, after treating with estradiol combined testosterone , compared with cases, the serum level of C, TG and HDL were lower and PT , APTT were longer ( P <0.05 ), had no significance with controls . Conclusion The synergistic effect of estradiol and testosterone can mediate the lipids , reduce the level of LDL , regulate the coagulation function , reduce the risk of coronary heart disease , and also provide a new strategy for hormone therapy in coronary heart disease .

Objective The application value of CTA for BA in interventional theray of lung cancer.Methods 15 patients with lung cancers including central type(13 cases)and peripheral type(2 cases) proven by pathology were analyzed prospectively.They were all examined with contrast enhanced.MDCT and the data were sent to the workstation and reconstructed with thin section multi-planar reformation(MPR),maximum intensity projection(MIP)and volume rendering(VR).Results All cases of central type lung cancer were supplied by the bronchial artery including two by the bronchial artery and intercostal artery,clearly demonstrated on the scans with the origin,branches and routes.One case of peripheral lung cancer was supplied by the bronchial artery and the other could not find the definite supplying artery.Conclusions CTA of BA for lung cancer can provide the accurate localization and other reference data for interventional therapy.

Objective To investigate the effect of tigecycline on serum procalcitonin and its efficacy in the treatment of elderly chronic obstructive pulmonary disease (COPD) and nosocomial infection. Methods 82 elderly patients with COPD with nosocomial infection were selected and randomly divided into two groups with 41 cases of each group, the control group received routine treatment combined with cefoperazone and sulbactam, and the experimental group received routine treatment combined with tigecycline, 2 weeks for a course of treatment. The serum inflammatory factors and laboratory related indexes, clinical efficacy and bacterial clearance were compared after the treatment. Results Compared with control group, the levels of serum high-sensitivity C-reactive protein (hs-CRP), interluekin 6(IL-6) and tumor necrosis factorα(TNF-α) were significantly lower, and the serum levels of PCT and NO were lower(P < 0.05). The total efficacy of experimental group was 90.24%, which was higher than 70.73% in control group (P<0.05). The bacterial clearance rate in the control group was 63.42%, which was lower than the experimental group of 87.80% (P < 0.05). Conclusion Tigecycline in the treatment of COPD and nosocomial infection in elderly patients is curative effective and it can reduce the serum levels of PCT, NO and inflammatory factors with high safety.

Objective To analyze the relationship between dynamic change of GPI-80 and disease severity and prognosis of childhood anaphylactoid purpura. Methods Patients were collected and divided into three groups according to their clinical features: purpura group (purpura only), mixed group (purpura + arthritis + gastrointestinal bleeding) and nephritis group. There were 20 patients in each group. GPI-80 expression on the neutrophils was detected by flow cytometry during acute and regressive phases of the disease. GPI-80 expression was compared among different groups and different phases. Renal biopsies were performed in 20 nephritis patients. Results GPI-80 expression was significantly increased in all patient groups compared with that in the normal control (P 0.05). No significant difference of GPI-80 expression was found among 20 nephritis patients with different pathological patterns. Forty-two patients (10 in purpura group, 15 in mixed group, and 17 in nephritis groups) were followed up and GPI-80 expression was detected at the time of discharge and 2 weeks after discharge, the results showed that GPI-80 expression was decreased from 93.26% (?7.89%) at acute phase to 91.37% (?6.9%) at regressive phase with an average interval of 13.5 days. Most of them (35/42) further decreased to 38.44% (?7.8%) in 2 weeks after discharge. GPI-80 expression remained high in 7 patients for 2 weeks after discharge and relapsed in 5 patients within 1 month after discharge. Conclusions High GPI-80 expression is related to the severity of the disease. The decrease of GPI-80 takes place later than the improvement of clinical symptoms. Children with persistently high GPI-80 expression are likely to relapse. It seems that there is no correlation between GPI-80 expression and different pathological patterns of nephritis.
