Objective To explore the method of culture of rat adipose-derived stem cells(ADSCs) and differentiation induction into myoblasts. Methods Adipose tissues were obtained from SD rats,and were isolated by enzyme digestion and cultured into ADSCs.The expression of surface antigen CD90,CD105 and CD34 was detected by immunofluorescence and flow cytometry.ADSCs of the second passage with logarithmic growth were obtained,and culture media containing 5-azacytidine(5-aza) and basic culture media were employed for cells in induction group and control group,respectively.The induction lasted for 7 d,14 d,21 d,28 d and 35 d,respectively.Cell growth and cell morphology were observed by inverted phase contrast microscope,and immunofluorescence and flow cytometry were utilized to detect the expression of myoblast specific antigens desmin and myosin. Results ADSCs were successfully isolated and cultured,and were identified to be stem cells.On the 28th day of induction,cells in induction group displayed "swirl" morpholgy,and multinucleation was observed.It was revealed by immunofluorescence and flow cytometry that the highest expression rates of desmin and myosin were 52.57% and 50.04%,respectively on the 28th day of induction,while there was no expression before induction and in control group. Conclusion ADSCs can be isolated and cultured from rat adipose tissues,and can further differentiate into myoblasts after induction by culture media with 5-aza.The expression of myoblast specific antigen is the highest on the 28th day of induction.

AIM: To evaluate the effect of the chosen incision on corneal astigmatism after implantable collamer lens ( ICL) surgery.
METHODS:The study included 195 eyes of 102 patients, and all eyes were randomly divided into two groups: the chosen incision group ( Group A, 97 eyes) and temporal corneal incision ( Group B, 98 eyes ) . Before the operation, and 1wk, 1mo and 3mo after the operation, each patient was examined with corneal topography to observe the changes of corneal astigmatism.
RESULTS: Preoperative corneal astigmatisms were (1-26±0. 35) D in group A and (1. 28±0. 38) D in group B, thus there was no statistically significant difference ( P>0-05). One week postoperatively, the astigmatism were (0.93±0.29)D in group A and (1.32±0.33)D in group B. One month postoperatively, the astigmatism were (0. 85±0.16)D in group A and (1.27±0.18)D in group B. Three months postoperatively, the astigmatism were ( 0. 80±0-13)D in group A and (1. 25±0. 20) D in group B. The differences between the two groups were statistically significant (P<0. 01).
CONCLUSION: The chosen incision can reduce postoperative astigmatism to a certain extent after ICL surgery.

Background The injury or surgery of cornea cause the proliferation of corneal stromal cells and scar formation.Recent research showed that cureumin can obviously reduce the degree of fibrosis of tissue.But if curcumm play inhibitory effect on corneal keratocytes fibrosis is rarely reported.Objecttve This studv was to investigate the effect of curcumin on the transformation of corneal keratocytes into fibroblasts in vitro and further explore the antifibrotic effect of curcumin on corneal keratocytes.Methods The murine corneal keratocytes from 150 BALB/c mice were isolated and primary culture in DMEM culture medium containing 10% fetal bovine serum and then divided into blank control group(inducer group,CG),low-dose group(CG+7.5 mg/L curcumin),mediumdose group(CG+10.0 mg/L curcumin),high-dose group(CG+12.5 mg/L curcumin),non-inducer group.Seven days following intervention,the expression of cell markers such as keratocan,aldehyde dehydrogenase(ALDH),decorin and fibronectin-1 in keratocytes were analyzed by RT-PCR.The effect of curcumin on cultured murine corneal keratocytes proliferation was evaluated by MTS technique.The expression of fibronectin-1 in murine cornea was investigated by immunofluorescence assay.Results The primarily cultured keratocytes showed tlIe fusiform-like shape with the abundant cytoplasm and big nuclei.In the presence of curcumin,the mRNA levels of keratocan and ALDH were down-regulated and those of CD90 and decorin were up-regulated,showing the significantly differences with the increase of dose(P<0.05),but the expression pf fibronectin-i was not obviously changed with the alteration of dose of curcumin. MTS showed that the inhibitory rates of curcumin on keratocytes in 10.0 mg/L and 2. 5 mg/L groups were enhanced in comparison with 7.5 mg/L group, showing statistically significant difference among three groups( F = 956.00, P<0.05). The expression of fibronectin-1 was found in the corneal keratocytes with the red fluorescence in stroma. Conclusion Curcumin can inhibit the fibrosis of corneal keratoeytes in a dose-dependent manner. These results offer a preliminary theoretical basis for the application of curcumin in controlling corneal scar formation during wound healing.

Background Corneal chemical burn is one of blinding eye diseases.Previous therapies for corneal chemical burn is limited to certain extent.However,transplantation of adipose-derived mesenchymal stem cells (ADSCs) for corneal diseases is drawing more and more attention.Objective This study was to observe the effect of rabbit ADSCs transplantation for ocular alkali burns and explore its mechanism.Methods Rabbit corneal stromal cells (CSCs) were isolated and cultured by suspended matrix method,and rabbit ADSCs were obtained and digested from inguinal fat tissue with enzyme digestion method (0.25％ trypsin) and identified by flow cytometry.CSCs cocultured with ADSCs,and CSCs-induced ADSCs were identified by double-label of with immunofluorescence and reverse transcription PCR (RT-PCR).Then induced or uninduced ADSCs were inoculated on amniotic membrane to prepared ADSCs-amnion patch.Corneal alkali burn models were established in the right eyes of 60 New Zealand rabbits by placing a filter paper with 1％ NaOH solution at the central cornea for 50 seconds.The models were randomized into the induced ADSCs+ amnion implanted group,the uninduced ADSCs + amnion implanting group,amnion implanted group and model group.Corneal opacification and neovascular area were examined and corneal inflammation was graded by slit lamp microscope 1 week,2 weeks and 1 month after surgery.The contents of CD45,interferon-γ (IFN-γ) and interleukin-10 (IL-10) in corneal homogenate as well as vascular endothelial growth factor (VEGF) in aqueous humor were detected by ELISA assay.The use and care of experiment animals followed the Statement of ARVO.Results ADSCs showed the positive responses for CD105,CD29,CD44 with the positive rate 90.23 ％,88.56％ and 98.88％,respectively.CSCs was positively reactive for vimentin.The double-label staining was positive after coculture of CSCs with ADSCs.Hematoxylin-eosin stain exhibited that ADSCs grew well on the amnion.Corneal porcelain opacity and a lot of new blood vessels were seen in the model group,and corneal was clear in the induced ADSCs+ amnion implanted group 1 month after surgery.The inflammatory scores were 1.65 ±0.18,2.05 ± 0.17,2.68±0.25,2.90 ±0.18,and the areas of neovasculization were (10.59 ± 1.78),(22.58 ± 1.63),(37.98 ± 1.90),(45.37±1.65)mm2 respectively in the induced ADSCs+ amnion implanted group,uninduced ADSCs+ amnion implanted group,amnion implanted group and the model group.The inflammatory scores of 1 week,2 weeks,1 month after operation among the four groups had statistically significant differences (F =280.826,330.172,465.707,all at P =0.000),and the areas of neovasculization of 1 week,2 weeks,1 month after operation among the four groups had statistically significant differences (F=60.020,670.811,1 510.231,all at P =0.000),the inflammatory scores in the induced ADSCs + amnion implanted group were remarkably lower than those of the other groups,the areas of neovasculization in the induced ADSCs+ amnion inplanted group were smaller than those of the other groups (all at P＜0.01).In 1 month after surgery,the contents of CD45,IL-10,IFN-γ in cornea and VEGF in aqueous humor were statistically different among the groups(F =916.545,1 739.358,462.134,129.126,all at P =0.000).Compared with the uninduced ADSCs+ amnion implanted group,amnion implanted group and the model group,CD45 and IFN-γ contents were declined,and IL-10 content was elavated in the induced ADSCs+ amnion implanted group (all at P＜ 0.01).In addition,VEGF contents in aqueous humor were significantly lower than those in the other groups (all at P＜0.01).Conclusions Rabbit CSCs-induced ADSCs amnion patch transplantation is effective for the reconstruction of ocular surface after alkali damage probably by differentiation of ADSCs into epithelial-like cell after CSCs induced.Moreover,amnion can alleviate immuno-inflammatory response and suppress neovascularization.

Objective To explore the prevalence rates of disabilities among the ethnic minority people in China. Methods Utilizing stratified, multiphase, and cluster probability sampling design, 2 526 145 persons were investigated and screened by trained interviewers,including 297 761 persons with ethnic minority backgrounds. Respondents scoring positive for potential problems were referred to physician for further diagnosis on disability and on scale measurement.Results The overall prevalence rate of disability for both ethnic minority and Han population were 6.24% (95%CI:6.16%-6.51% ) and 6.41% (95% CI: 6.38%-6.51% ) respectively. The total aggregate age-adjusted prevalence rate of disability was 7.31% for persons with ethnic minority. The prevalence rate of disabilities in male was significantly higher than that in females (7.31% vs. 6.75% ). The ranking of prevalence rates on different type of disabilities were: physical disability 1.90% (95%CI:1.89%-1.91%), hearing disability 1.34%(95%CI: 1.33%-1.35%), multiple disability 1.14%(95%CI:1.13%-1.15% ), vision disability 0.99% (95%CI: 0.97%-1.01% ), psychiatric disability 0.38%(95%CI:0.37%-0.40% ), intellectual disability 0.38% (0.37%-0.39%) and speech disability 0.12% (0.11%-0.13% ). Cerebral Palsy, genetic diseases, tympanitis, cerebral disease and mental retardation (not including unknown items) were the major causes for disabled children with ethnicity background.Degenerated diseases, including osteoarthropathy, cerebrovascular disease, elderly-related deafness or cataract were most important causes for ethnic minority persons aged 60 or over. Injury, including traffic accident was important disabled-related factor for persons with minority ethnicity aged 15-59.The main causes and ranking of causes for ethnical minority were similar with that for Han population.Conclusion The prevalence rate of disability for ethnic minority persons was significantly higher than that for Han population in China. Prevention for different types of disability should be provided accordingly to persons with ethnic minority, in different age groups.
