AIM: To report the use of modified four ports pars plana vitrectomy in managing a dislocated posterior chamber intraocular lens.METHODS: A young man with bilateral pseudophakia and dislocated PC-IOLs had undergone modified four ports pars plana vitrectomy in relocating a dislocated posterior chamber intraocular lens. This procedure was surgically less tedious and demanding compared with previous methods of IOL retrieval.RESULTS: No significant intra- or post-operative complication was noted. The visual recovery of the operated eye was rapid with the best corrected visual acuity at 14 months post-operation being 0.5. In contrast, the right eye without operation due to patient refusal developed total retinal detachment with hand movement visual acuity.CONCLUSION: Modified four ports pars plana vitrectomy may be a more ophthalmic surgeon friendly alternative in the retrieval of dislocated IOL.

Workers with high quality, high job satisfaction levels and high stability are indispensable to the sustainable development of community health services. The present research aimed to find out about the scope of job satisfaction and stability of community health workers by means of designing relevant questionnaires and sample survey and to identify the major factors affecting the scope of job satisfaction and stability. The research found that among the community health workers, those engaged in preventive healthcare were a group with the lowest job satisfaction level and there were six factors affecting the scope of job satisfaction, including working conditions, the effect of the implementation of rules and regulations, respect from and care by leaders and so on. It also found that 45.1% of the workers once had the thought of leaving their community health centers or stations and there were 5 factors affecting job stability, including environment for medical practice, doctor-patient relationship, scope for bringing one's ability into play and so forth.

Objective To understand the environmental estrogens contamination of tap water and source water. Methods Environmental estrogens in the water samples were concentrated by macroporous adsorption resin H103. The effect of environmental estrogens in concentrated samples was assessed by the recombinant yeast system. Results The results showed that some source water and tap water really contained environmental estrogens. The activity of environmental estrogens in concentrated samples of some source water increased as the volume of concentrated sample increased. The concentrate of 100 ml water sample could show the estrogenic effect. Conclusion Some source waters and tap waters in China have been contaminated by environmental estrogens. Environmental estrogens in source water can not be removed completely by drinking water treatment system of city.

This study was based on live yeast cell derivative (LYCD), which was produced by live yeast cell stressed with high temperature and H 2O 2. The results showed that pretreating of low dose(37℃and 0.2mmol/L H 2O 2) could increase the content of GSH and the activity of SOD and CAT. These pretreatment could induce the resistance to lethal concentration of H 2O 2. LYCD was produced by yeast treated with 37℃ and 0.2mmol/L H 2O 2. And it was found that the survival of yeast treated with lethal concentration of H 2O 2 obviously increased, while LYCD was added in yeast culture. It indicated that LYCD could have resistance to oxidative condition.
