Background Stroke unit is the most effective treatment method to benefit stroke patients. Our study is to evaluate the early effectiveness of a hospital stroke unit (SU). Methods Three hundred and ninety-two patients who had suffered from acute strokes and who were admitted to our hospital between December 2001 and January 2003 were recruited for this controlled study. All patients were sent at random to either the SU or the general ward (GW) for treatment. The following indices were measured by: Barthel Index (BI),National Institute of health Stroke Scale (NIHSS),Oxford Handicap Scale (OHS). Results The mean change in BI score between the day of admission and the day of discharge was 20.00±24.36 for the SU group and 10.63±23.59 for the GW group. A difference that is statistically significant ( P =0.000). The mean change in NIHSS score was -2.01±6.61 for the SU group and 0.55±7.44 for the GW group. A difference that is also statistically significant ( P =0.000). Finally,the mean change in OHS score was -0.74±1.04 for the SU group and -0.28±0.98 for the GW group,also a statistically significant difference ( P =0.000). Among SU patients,patient satisfaction was higher ( P =0.000),the rehabilitation success rate was higher ( P =0.000),and there were fewer complications ( P =0.000).Conclusion Compared to GW patients,stroke patients treated in a special SU were able to return to normal daily activities earlier,with better social abilities,and have reduced neurological defects,without increasing the overall economic burden.

Modeling approach using discrete event simulation has been proven to work well in modeling in health care. The aim of our paper is to propose a simulation approach which shows realistic models presenting different possible treatments in different stages of diabetic retinopathy. We have presented three models in order to choose the best treatment for diabetic retinopathy patients. The first model describes the flow of a patient through stages without any medical treatments. It takes 13 years to reach blindness. The second model which includes the laser photocoagulation treatments leads to blindness after 46 years. Then, the third model illustrates the involvement of vitrectomy operation and delays blindness by 23 years. To construct the models, data were taken from experienced doctors and professors of the ophthalmology department in the University hospital Habib Bourguiba and the endocrinology department in the University hospital Hedi Chaker in Sfax, Tunisia. Our objective is to delay reaching the blindness stage as late as possible. Three models were developed, verified and validated through many iterative implementations with ARENA simulation software.

Quality assurance （QA） and quality control （QC） are fundamental aspects of any laboratory measurement. However, in comparison with other medical disciplines, the need for QA and QC in laboratory andrology has been recognized only recently. Furthermore, there is evidence that the effort required to undertake QA and QC has not been wholly welcomed by some clinicians. Nevertheless, accrediting bodies and regulatory authorities increasingly require evidence that laboratories have effective QA and QC measures in place because both are central to the quality management processes. Following the publication of the 5th edition of the World health Organization Laboratory Manual, existing QA and QC systems will need to be updated to take into account some of the methodological changes recommended by the manual. Three of these are discussed in this commentary; they relate to：（i） the move to infer semen volume from its weight; （ii） the re-classification of sperm motility grades from four to three; and （iii） the publication of a lower reference limit for morphology of 4% （with a corresponding 95% confidence interval of 3%-4%）. The importance of QA and QC in all laboratory tests, including up and coming new tests to assess sperm DNA integrity, is discussed. The need for adequate initial training and continuing professional development programmes to support laboratory scientists performing andrology is also described.

A sigma-edged design of intraocular lens （IOL） is proposed to minimize the reflected glare images associated with the edge. The optimal sigma inverse edge is investigated when pupil diameter is 5.0 mm by the established Escudero-Sanz＇s wide angle model. The non-sequential ray tracing program of Zemax-EE （Zemax Development Corp., San Diego, USA） is used to investigate the sigma edge of reducing the potential for edge glare phenomena. The results show that sigma-edged design can significantly reduce the reflected glare intensity on retina if the angle of its inverse edge is taken from 20 to 70 degrees.

In the 21st century medicine is characterized by population problem, the great impact of computer and information technology, the contribution of genetics development to disease prevention and treatment, and the reform of health care system. By 2025, there will be 274 million people over 60 years old and cancer may be the primary killer as well in China. The incidences of cancers of the lung, intestine, and breast are on the rise; the incidence of cervical cancer is decreasing in developed countries while increasing in developing ones.
