BACKGROUND:Hydrophilic acrylic materials with good biocompatibility have been widely used in clinic. However, there are some problems about the biocompatibility and safety of hydrophilic acrylic intraocular lens after long-term clinical application. OBJECTIVE:To discuss the biocompatibility and stability issues and corresponding processing methods after hydrophilic acrylic intraocular lens implantation. METHODS:A computer-based search of Wanfang and PubMed database was performed for articles related to clinical application of hydrophilic acrylic intraocular lens published from 2005 to 2014. The keywords were “hydrophilic acrylic,intraocular lens” in Chinese and English, respectively. A total of 618 articles were initialy retrieved, and finaly 35 articles were included in result analysis. RESULTS AND CONCLUSION:As the hydrophilic acrylic intraocular lens is foldable, a smal incision is required for implantation and the operation is simple that cause less damage to the patients. In addition, the hydrophilic acrylic intraocular lens has poor bacterial and inflammatory cel adhesion, which leads to a low probability of infective endophthalmitis after implantation. But there is a high incidence of posterior capsule opacification as wel as some refractive errors and visual quality problems after implantation. Taken together, to solve these problems depends on the continuous improvements and updates of intraocular lens materials and designs.

Sepsis,a complex clinical syndrome resulting from a harmful and damaging host response to infection, is the leading cause of mortality in intensive care units.Early diagnosis and appropriate intervention can improve the prognosis of patients with sepsis.Many studies have confirmed that sepsis at different stages is in different immune status.Priority used to be given to systemic inflammatory response, but immune-suppression has become the focus of study. Immune-suppression and secondary infection are the major causes of death of patients with sepsis.Study of sepsis is shifting to immune-suppression and its regulation mechanisms.

Objective To study the gastroscopic and pathohistologic mucosal changes in children′s chronic gastritis and to improve the diagnosis of the chronic gastritis in children.Methods Two thousand four hundred and forty children with upper-abdominal symptoms who were examined by gastroscopic observation were collected,and samples of gastric mucosa were examined by the same pathohistologist.And then the pathohistologic changes were analysed.Results All the 2440 children had different mucosal inflammation confirmed by gastroscope,and the pathologic results show that there were 2132 cases of chronic superficial gastritis(90.03%) and 76 cases of chronic atrophic gastritis(3.21%).Among 2440 cases,80 cases with intestinal metaplasia(3.37%),972 cases with lymphoid follicles(41.05%),409 cases with active inflammation(17.28%),902 cases with helicobacter pylori(Hp) infection(38.09%).Moderate and severe inflammatory were more predominant in patients with Hp infection,especially with lymphoid follicles or active gastritis,and the percentage of them were 50.79%,68.73%,73.53%,respectively.Conclusions Major chornic gastritis in children are chronic superficial gastritis,and the pathohistological changes are different from the adults.It also shows that there is a close relationship between gastric mucosal inflammation and Hp.

Objective To compare the phenotype of myeloid derived suppressor cells (MDSCs) separated from the bone marrow of mice 3 d and 7 d after cecal ligation and puncture ( CLP) and to elucidate its potential role in the accumulation and immuno-function of MDSCs by determining the expression of microRNA-146a(miR-146a)in order to explore the effect of miR-146 a on immonosuppression of MDSCs in sepsis .Methods A septic model was prepareol by CLP in adult male C57BL/6J mice.MDSCs(expressing cell-surface CD11b and GR-1 antigens )from bone marrow were harvested 3 and 7 days after CLP and were separated with magnetic bead sorting technique .Then,cytokines secretion and arginase-I activity were detected and the T cell proliferation in vitro and the expression of miR-146a of MDSCs (3 d and 7 d after CLP)were observed.Results MDSCs secreted mostly such promoting inflammatory factors as TNF-α, IL-6 3 days after CLP, but 7 days after CLP , they primarily secreted IL-10 and TGF-βwhich were anti-inflammatory factors . MDSCs had potent immunosuppressive properties by increasing T cell suppression in a late anti-inflammatory phase ( CLP3 d vs CLP7 d, P<0.05).In the meantime,miR-146a of the MDSCs in bone marrow was overexpressed in septic mice at 7 days(P<0.05). Moreover,the expression of miR-146a of the MDSCs in bone marrow of septic mice was higher at 7 days than at 3 days after CLP(P<0.05).Conclusion The data indicate that the phenotype of MDSCs evolves through early pro -inflammatory phase into the late anti-inflammatory phase .MDSCs have potent immunosuppressive properties in the late phase of sepsis . miR-146 a might play a crucial role in the regulation of immunosuppressive activity of MDSCs in late sepsis .

Objective To observe the abnormality on behavioral ability of transgenic mice for HRX-EEN fusion gene.Methods Transgenic mice for HRX-EEN fusion gene(transgenic group,n=12)and C57/BL mice(control group,n=12)were tested in hidden platform training(day 1 to day 4)and probe trial testing(day 5)in Morris water maze in which ability of spatial learning and retention was assessed.Results In hidden platform training,the latencies of transgenic group were longer than those in control group,and significant differences were observed between the two groups for day 2,3 and 4(P
