Twelve patients with huge rhegmatogenous retinal detachment were treated with electrocoagulation and/or cryosurgery supplemented with extrascleral buckling, annular knotting or macular sling technique. 11 cases were cured but failure occurred to one case. After treatment, the vision was improved in various degrees in different patients.It is concluded that even though the rhegma is large and the retina is wholly detached, the cure rate can be increased if careful preoperative examination and preparation is made, appropriate operative measures selected, electrocoagulation and cryosurgery reasonably adjusted, and the rhegma securely buckled.

Objective To investigate the relationship between exposure intensity and illumination time of blue light and replicative senescence of rat retinal pigment epithelial (RPE) ceils.Methods Thirty-six 12-14 weeks Wistar rats were kept in the cage with a blue-light bulb [(450±10) nm],and were randomly divided into four groups (no light,nature light,500 lx light and 1000 lx light illumination),each has nine rats.The rats in each group were further divided into three subgroups according to illumination time (one month,two months or three months).Eyeballs were collected after intraperitoneal injection of 10% chloral hydrate.The right eye of each rat was embedded in paraffin and sectioned for hematoxylin-eosin (HE)staining,while frozen sections of the left eye were stained for the senescence-associated β-galactosidase (SA-β-Gal).The data were analyzed by SPSS11.5 statistical software.Results The amounts of SA-β-Gal positive RPE cells were significantly different between all groups under the same illumination time 17 (P=0.000),and between all subgroups of different illumination time with same exposure intensity (P＜0.01)except for the control group (no light).Conclusion Blue-light can induce replicative senescence in rat RPE cells in an intensity and time-dependent manner.

In recent years, the theory of cancer stem cells has provided a new perspective on the treatment of cancers including breast cancer. The accurate sorting of breast cancer stem cells is critical. The sorting procedure is consist of 4 steps: isolation of side population, serum-free suspension culture,determination of specific cell surface markers and of the activity of aldehyde dehydrogenase 1 ( ALDH1 ) enzymatic through the ALDEFLUOR assay. Some studies choose drug resistance as an additional method for sorting cancer stem cells because of the enrichment of cancer stem cells after chemotherapy . The controversy about the sorting outcome of breast cancer stem cell mainly focus on molecular markers like CD44+ CD24- and ALDH1+ . The problem needed to be settled is to identify which sorting method and markers are appropriate.

Objective:To explore the therapeutic potential of preemptive targeting of the epitope spreading cascade by adoptive transfer after EAE onset of immunoregulatory T cells specific for the MBP87-99 spreading determinant.Methods:EAE was induced by PLP139-151 in SWXJ mice, all mice were weighed and examined daily for neurologic signs. On days 6 after EAE onset, mice were injected with IL-2prom→IL-10cDNA-transfected Th2/Tr1-like T cells specific for MBP87-99,PLP104-117,or BSA. Finally demyelination was quantified by analysis of digitized images of PLP immunostained spinal cord sections.Results:Mice received Th2/Tr1-like T cells specific for MBP87-99 had a significantly improved clinical outcome(P=0.02) compared with control mice, reduction in the relapse rate and delay in mean time to onset of first relapse were also observed(P

Objective:To investigate the effect of early intervention on intelligent development of the premature infants. Method:62 premature infants were randomly assigned to the intervention group and the control group. The early intervention began from the birth of the infants to their 2 years old.Result:At the age of one and two, the mental development index (MDI) and psychomotor development index (PDI) were significantly higher in the intervention group than in the control.Conclusion:Early intervention can improve intelligent development of premature infants.
