Analysis of setbacks found in the existing system and mechanism of public hospitals. Based on the health reform principles of Separation of administration and management, Separation of administration and operation, Separation of prescribing and dispensing, and Separation of for-profit hospitals and nonprofit hospitals, the authors named the following roadmap for public hospital governance reform. First, set up a management committee for each public hospital to coordinate the government function for medical service; set up a public hospital authority to upgrade the management level of these hospitals; transform functionality of health authorities to encourage diversity in medical service providers. Second, establish the tiered decision making mechanism, autonomous operation system and diversified supervision system, to separate administration and management. Third, formulate articles of association for hospitals to encourage their evolution to legal entities, consolidating the government reforms by legal means.

The implantable axial blood pump, driven by external electromagnet, is studied recently. It oscillats when it is running because of the elastic implanted environment and driving force disequilibrium, etc. In this paper, a model of single erythrocyte in vibrated flow field was built to simulate the deformation and force of the erythrocyte. By using the mechanical injury principle of blood in blood pump, we studied the injury of a single erythrocyte resulted from oscillating boundary flow field. The research results indicated that the shape of the erythrocyte, force and velocity field nearby, which are affected by oscillating boundary flow field, all cause injury to the erythrocyte. All the researches shown in the present paper are expected to provide theoretical foundation for lightening hemolysis by the blood pump.

Objective To investigate the expression of Golgi protein?73(GP73) and Ki?67 antigen in gallbladder carcinoma ,and to analyze their correlations with proliferation ,invasion ,and prognosis of gallbladder carcinoma. Methods Streptavid?in?peroxidase (SP) immunohistochemistry was used to detect the expression of GP73 and Ki?67 in surgically resected specimens of 58 gallbladder carcinomas ,15 gallbladder adenomas and 15 gallbladder polyps samples . Results The positive rates of GP73 and Ki?67 protein in gallbladder carcinomas were 72.4% and67.24%,respectively ,which wer significantly higher than those in gallbladder adenomas(GP73:40.0%,Ki?67:26.7%,P<0.05)and in gallbladder polyps(GP73:13.3%,Ki?67:25.0%,P<0.05).The expression of GP73 was positively correlated with tumor differentiation ,Nevin staging and lymph node metastasis(P < 0.05), and the expression of GP73 was positively correlated with tumor differentiation ,Nevin staging(P < 0.05). GP73 expression was positively correlated with Ki?67 expression in gallbladder carcinoma (r = 0.473 ,P = 0.000). Patients with negative expression of GP73 and Ki?67 had longer survival time than those with positive expression of GP73 and Ki?67. Conclusion The expression of GP73 and Ki?67 was associated with proliferation ,invasion of gallbladder carcinoma. The combined detection of GP73 and Ki?67 is conducive to judging the progress and prognosis of the gallbladder carcinoma .

In order to reform the medical talent evaluation system, establish evaluation systems of physician competency, and implement physician resources management systems according to work position, and the compensa-tion system which reflects the value of medical services, The basic principles and standards of different physician tiers and grades are created in Shenzhen based on literature review, expert consultation and the methods from the American Centers for Medicare and Medicaid Services ( CMS) . Some results have achieved, including medical competency as-sessment of a certain number of physicians in the pilot project ( the coincidence rate of special hospitals is higher than general hospitals, respectively 78. 9% and 44. 8% ), comprehensive personnel systems reforms in public hospi-tals, and the trial selection of medical talents. The paper also provides some implications:The cognition of all sectors of society and physician themselves should be improved, Transitional policies for position recruitment and performance pay needs further improvement. Meanwhile, the grade evaluation system of non-physicians must also be given greater attention.

Stage 4 of chronic kidney disease ( stage 4 CKD ) is induced by insufficiency of spleen and kidney , disorder of qi activity, poor circulation of blood and body fluid metabolic disorders. It is a disease due to the internal generation of dampness , turbid , stasis and toxin . Clinical observation has already demonstrated that in-sufficiency of spleen and kidney is the key pathogenesis and characteristics in stage 4 CKD . In this article , the necessity of regulating and nourishing spleen and kidney on stage 4 CKD was discussed from two aspects , which were the disease characteristics and the connotation of regulating and nourishing spleen and kidney . It provided brief and essential syndrome differentiation and treatment strategies in the clinical treatment of stage 4 CKD .

Chronic renal failure ( CRF ) , which is a progressive disease , is difficult to be reversed after the pathological damage was formed . Hence , a variety of integrated and complementary therapies should be used for the lifelong treatment and regulation . This article suggested that therapeutic methods should be given ac-cording to different stages of CRF in its development . Chinese medicine comprehensive therapy should be given to the early and middle stage chronic renal failure patients in order to delay the disease progression . In the uremia stage , replacement therapy should also be used as the basic treatment in order to reduce the general complications of dialysis or a kidney transplant , thereby improving the quality of life of patients . The integra-tion of Chinese medicine therapy on CRF are from three aspects , which are Chinese medicine decoction based on syndrome differentiation , Chinese medicine external therapy and Chinese medicine featured CRF management in order to receive better therapeutic effects .
