Ophthalmic plastic and reconstructive surgery is an interdisciplinary speciality,it includes cosmetic surgery,oculo- plastic surgery and orbital surgery.The current mainly problems and strategies will be discussed in this paper,the status and progresses of cosmetic surgery,including cosmetic eyelid surgery,anesthetic injection methods,and laser facial rejuvenation.Present existing prob- lems and their countermeasures in ocnloplastic surgery,including eyelid malignant tumor,eyelid defects,blepharospasm and anoph- thalmic socket disorders.Problems and management of orbital surgery,ineluding thyroid-associated orbitopathy,orbital fractures,and orbital deformities.At last,the mainly problems and corresponding measures of development of ophthalmic plastic and reconstructive surgery will be discussed.(Ophthalmol CHN,2007,16:365-367)

Objective To investigate the signal transduction of bFGF to regulate the colorectal carci- noma cell growth via PI3K/PKB pathway.Methods MTT assay was used to determine the suppressive effect of bFGF on the growth rate of LoVo cell;(?-~(32)P)ATP incorporation assay was used to detect the increased activity of PKB in LoVo cell;the RT-PCR technique was used to test the expression of cyclin A;Western Blot analysis was used to detect the expressions of PKB and cyclin A protein.Results When the bFGF worked on the LoVo cell at various times,it was found that the PKB activity of the LoVo cell was increased by the(?-~(32)P) ATP incorporation assay.By preprocessing by the depressor-LY294002 and bFGF,the activity of PKB was sig- nificantly reduced(P

Neural mass models are able to produce epileptic electroencephalogram (EEG) signals in different stages of seizures. The models play important roles in studying the mechanism analysis and control of epileptic seizures. In this study, the closed-loop feedback control was used to suppress the epileptic-form spikes in the neural mass models. It was expected to provide certain theory basis for the choice of stimulus position and parameter in the clinical treatment. With the influence of measurement noise taken into account, an unscented Kalman filter (UKF) was added to the feedback loop to estimate the system state and an UKF controller was constructed via the estimated state. The control action was imposed on the hyper-excitable population and all populations respectively in simulations. It was shown that both UKF control schemes suppressed the epileptic-form spikes in the model. However, the control energy needed in the latter scheme was less than that needed in the former one.

To meet the requirements for the development of marine resources and military operations, divers usually dive deeper than the depth at which narcosis is present during air diving.Under this condition, heliox is required for this div-ing.Sofar, some countries have developed their own decompression tables for routine heliox diving.The best-known is tables from USA and France.In the preceding century, tables of Former Soviet Union and France used for routine heliox diving were introduced into China.On the basis of both types of tables,Chinese Navy developed their own tables for this purpose. In this paper, we summarized the characteristics of these tables from 5 countries and compared them in terms of structure, oxygen use, total decompression time, first stop and other features.This may provide a basis for future modification of ta-bles used in China and the development of new tables for routine heliox diving.

By analyzing data from a questionnaire survey on bilingual teaching, we evalueted the results of bilingual teaching for seven-year medical students and the main problems of bilingual teaching and solutions accordingly. An uneven English level on the part of teachers and students and imperfect materials etc. affect the overall results of bilingual teaching. Therefore persistent efforts need to be made in enhancing the teachers' English level, improving teaching methods and compiling proper textbooks so as to genuinely improve the bilingual teaching program.
