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.

Phospholipid fatty acids are the major constituents of the membranes of all living cells, and different groups of microorganism synthesize a variety of PLFA through various biochemical pathways. Several PLFAs can be used as "signatures" to analyze changes in microbial biomass and microbial communities structure. More and more PLFA method was used in soil microbial analysis. This article briefly reviewed the applications of PLFA methods in soil microbial analysis.

Preimplantation genetic diagnosis is the integration of both assisted reproductive technologiesand molecular genetic technologies.Since the birth of the first healthy females after PGD in 1990,re-markable advances have been achieved in this field.Most research in PGD is focused on new methods toimprove the sensitivity and accuracy of single cell analysis.The principal problems in single cell PCR in-clude amplification failure,ADO and contamination.Fluorescent PCR with multiplex amplifications ofhighly polymorphic markers is a highly effective strategy to avoid contamination and detect ADO.The ad-vantages and disadvantages of fluorescence in situ hybridization to detect age-related aneuploidy are stillunder debate.We summarize the most recent developments in this review,and also introduce our own ex-periences in PGD.
