AIM: To investigate the clinical effect of phacoemulsification and intraocular lens ( IOL ) implantation for cataract patients after corneal refractive surgery, and to compare the accuracy of the different refractive IOL.
METHODS:The data of 120 myopia cases (160 eyes) in our hospital, who underwent cataract surgery and corneal refractive surgery were analyzed. Corneal curvature K value before corneal refractive surgery were obtained and calculated by using history method. Corneal curvature correction numerical method and corneal topography were used to record K value of patients with incomplete data before and after treatment. The K value was substituted into the formula. By comparing the actual cataract surgery and refractive state expected refractive status (-0. 50D), the accuracy of IOL refractive obtained from three methods was compared.
RESULTS: The average best corrected visual acuity before cataract surgery was 0. 25 ± 0. 05, and it was improved ( 0. 80 ± 0. 05 ) after surgery. The average spherical equivalent (SE) was -1. 98±1. 75 before surgery and +0.85±3.38 after surgery (P<0.05). The K values of 48 cases were calculated by clinical history method ( CHM ) and that of 73 cases was calculated with the adjusted keratometry method ( AKM) . The K values of 39 cases were calculated using the corneal topography method ( CTM) .
CONCLUSION: For patients with corneal refractive surgery, the appropriate method can be selected according to clinical symptoms, history, etc. and this may help to accurately calculate IOL. For patients with complete data, CHM can be used to provide corneal K values, while for those with incomplete data, AKM and CHM can be used.

Objectives To explore the effects of control measures and dynamic prevalence of drinking water endemic fluorosis in China, to provide basis and technique support for endemic fluorosis control in China. Methods The survey was carried out according to the national surveillance Scheme of Endemic Fuorosis. The fulfillment of control measures and the quality of water improving projects were surveyed. Household water sample and urine of children aged 8-12 years were collected and fluoride content was detected by iron selective electrode method. Check the teeth of children aged 8-12 years. Dental fluorosis was diagnosed by Dean's method. Results projects were build in 84 endemic villages in 2006, and the average water improving rate came to 73.98% fluoride contents of half the surveyed spots were over the standard, mainly between 1.0-2.0 mg/L, and the urine controlled just in only few spots and it was in moderate or severe status in some endemic areas for many years. Conclusions Little progress of control measures in drinking water endemic fluorosis counties surveyed has been made in these two years. Projects of running out of status and over standard of water fluorosis are frequently seen. Dental fluorosis in many spots is not controlled.

Bone Marrow Mesenchymal Stem Cells (BMSCs) are ideal seed cells for cell therapy,which have been through many long-term studies of in vitro and animal disease model treatment and have been widely used in preventing and treating a variety of clinical diseases caused by aging and other damage,including bone injury and regeneration,neural degenerative and injury,myocardial injury,liver cirrhosis,diabetes,lung disease and so on.BMSCs application in the treatment of orthopaedic disease is the most common and effective.By retrospective literature review,we summarize the BMSCs transplantation application in Orthopaedic disease treatment.As an ideal cell source,BMSCs was first applied in bone tissue engineering,mainly used in the treatment of long bone defect and bone nonunion;Recently,the research trends of clinical BMSCs application turned to treat degenerative diseases and genetic disorders because of its great potential,including osteoarthrits,femoral head necrosis,disc degeneration,spinal cord injury,knee varus,osteogenesis hypoplasia,hypophosphatasia and so on.The safety and efficacy of BMSCs treatment are the key issues in clinical cell therapy.There is no side effects and complications after BMSCs treatment,prove its clinical application is safe.But due to type and degree of disease and individual differences,therapeutic methods including injection method,effective concentrations,treatment window selection,cycle and therapeatic effects have a bigger difference.There is still no uniform of recognized operation standards for the treatment of the same type of disease.So BMSCs transplantation requires effective control during whole medical process and its application in orthopedic diseases is still lack of large-scale multicenter clinical study.Therefore,this review focuses on induction,summary and analysis in the research status of BMSCs in bone disease treatment,and provide new ideas and methods for BMSCs transplantation in orthopaedic disease prevention and treatment.

Exosomes are cell-derived vesicles that contain protein and RNA from the same source and function. The vesicle has a diam-eter between 30 and 100 nm. Exosomes are the natural carriers and have been recently used as drug delivery system for cancer treat-ment. MicroRNAs (miRNAs) function in RNA silencing and regulation of gene expression. They can exist as intracellular and extracellu-lar miRNAs. Extracellular miRNAs can function as secreted signaling molecules that affect receptor cell phenotype. They can also re-flect molecular changes in donor cells. Therefore, extracellular miRNAs can be potentially used for diagnosis and therapeutics. Studies show that the volume of exosomes in cancer patients' blood is higher than that in normal controls. The ability to package cancer-relat-ed miRNAs is a biological function of exosomes. In conclusion, specific miRNAs transferred by exosomes may play an important role in the pathogenesis of tumor or cancer. This paper presents a summary of research on exosomes as the carrier of miRNAs in the develop-ment and treatment of cancer.
