OBJECTIVE:To provide reference for reconstructing medical regulatory system in China. METHODS:Through in-troducing medical regulatory setting mode in Britain and USA,combining the situation and problems of medical regulatory setting in China,and the assumption was put forward for medical regulatory system construction. RESULTS & CONCLUSIONS:Adher-ing to the principle of legalization,independence and speciality,Britain and USA set up various types medical regulatory in each professional field led by health departments. These medical regulatory institutions are charged with drug instrument regulation,medi-cal regulation monitoring,medical insurance monitoring,and other responsibilities. In China,medical regulatory function scatters in Food & Drug Administration,Health and Family Planning Department,Human Social Security Department,Price Department, etc.There are some problems which go against the relief of“difficulty and high cost of getting medical service”and“falsely high drug price”,such as low legalization,unclear regulatory function,poor independence and speciality. So,“super health”medical regulatory system,covering administration department,industry regulator institutions and professional technology institutions led by National Health and Family Planning Commission,should be established through grasping“super-ministries”reform opportunity and integrating medical regulatory function of Food & Drug Administration,Health and Family Planning Department,Human So-cial Security Department,by referring to Britain and USA experience.

·Electroretinogram (ERG) is an objective examination in evaluating retinal function, which is also suitable to evaluate retinal function of multiple ophthalmic diseases. ln recent years, studies have found that ERG can find functional changes prior to morphological changes of fundus examination in early diabetics, which provides a new way for researches of pathological mechanism, early diagnosis and prognosis evaluation for diabetic retinopathy, and then also provides a new therapy for diabetic retinopathy. ln this paper, using ERG in the diagnosis of early diabetic retinopathy was reviewed.

Objective: To rapidly construct bone-implant complex finite element model series using worksheet-driven CAD and finite element analysis software. Methods: The alveolar ridge and implant models were constructed by CAD software separately. Based on those models, the CAD models of different compositions of cancellous and compact bone and different implants were built and assembled. Electronic form software was utilized to drive the change of dimension in the process. All the models were imported into finite element analysis software and converted to finite element models after installation of different parts in the CAD software. Results: A total of 300 finite element models for different alveoli-implants were obtained through activating different versions of models. The models were of high quality and had no interference with each other. Conclusion: Our modeling method is rapid and highly effective. The series of models basically covers all types of alveoli,which provides a tool for studying the biomechanical characters of implants.

Objective To explore the reasons and the treatment counter-measures for secondary intracranial hemorrhage happens in the intracranial tumor craniotomy. Methods Retrospectively analyzed the clinical data of 15 patients with intracranial tumor who suffered secondary intracranial hemorrhage intraoperation. Summarized the tumor characteristics and the situation of corresponding vessels confined by second operation. Results In these 15 cases,the rank of course of disease was 6.5 months to 2 years, mean 1.2 years. The size of the tumor was big with diameter 4.62 ～5. 82cm,mean 5. 12cm,and the tumor was deep surrounding by large range edema,which led to intracranial hypertension. The emissary vein,bridging vein and cortical draining vein were considered as the corresponding vessels for ' secondary intracranial hemorrhage during the second operation carried out for all 15 cases. There wsa no death cases in this research and all patients recovered the nomal ability for self-caring after 3 months following up. Conclusion Sudden drawdown of intracranial pressure and perfusion pressure breakthrough of local vessels had relationship with secondary intracranial hemorrhage during craniotomy for intracranial tumor. Accurate judgement for the occurrence of secondary intracranial hemorrhage intra-operation and quickly taking the effective corresponding measures was the important strategy for prognosis improving for these patients.

Objective To explore hematoma piercing attract joint hematoma clearance to bone valves decompression technique in hematoma volume,skull,pressure high blood pressure brain hemorrhage treatment,and to further explore hypertension brain hemorrhage of reasonable surgery. Methods Hematoma in relatively large quantities of high intracranial pressure in hypertensive cerebral hemorrhage patients were randomly divided into experimental group and control group,and patients in the experimental group were implemented early hematoma puncture to attract a joint hematoma decompressive craniectomy treatment,and the control group were implemented the traditional hematoma de-compressive craniectomy treatment. The prognosis of the two groups were compared. Results The two groups were followed up for 6 months,and evaluated by ADL grade,between the two groups was statistically significant difference in ADL classification( P<0.01). Conclusion In the hematoma volume larger, high intracranial pressure in hypertensive cerebral hemorrhage in the surgical treatment of patients,the early line to attract a joint hematoma puncture decompressive craniectomy was a reasonable and feasible surgical method which can improve these patients prognosis.
