Objective To investigate the effect of Icariin ( ICA) experimental IgA nephropathy in rats and to explore related mechanisms .Methods Experimental IgA nephropathy rat model was established and then model rat were treated with or without different doses of ICA .Then, urine RBC, Urine protein and urine NAG were analyzed; IgA precipitation was detected with immunofluorescence staining;the protein level of NF-κBp65 and MCP-1 were examined by immunohistochemical staining;the mRNA level of IL-4, IL-10 and IL-13 were determined by quantitative PCR .Results The concentrations of urine RBC, Urine protein and urine NAG were reduced after ICA treatment , as companied by a decrease of IgA precipitation .Moreover, ICA treatment also decreased the protein level of NF-κBp65 and MCP-1, and the mRNA level of IL-4, IL-10 and IL-13.Conclusions ICA exerts a certain degree of efficacy on the treatment of experimental IgA nephropathy through regulating NF-κBp65 and MCP-1 expression and the immunoregulation mechanism .

K. There was no significant difference in the yield among the treatments of N+K, CK, P, N+P, and N, but the results of these five treatments were significantly higher than that of P+K and K. In addition, cichoric acid content did not considerably changed after treatment of various fertilizer combinations. For the second harvest date the yield of N, N+K, P, and N+P were 47.7%, 35.4%, 33.8%, and 12.3% higher respectively than that of CK, the yield of N+P+K, P+K, and K were 7.7%, 10.8%, and 28.5% lower respectively than that of CK. There was significant difference in the yield between the treatment of N and CK, the yield of K was significantly lower than that of CK. Conclusion The results indicate that cichoric acid content is not significantly affected by the treatment of various fertilizer combinations and the yield is strongly influenced by N fertilizer, weakly by P fertilizer, on the contrary the application of potassium chloride results in a decrease in yield.

AIM:To compare the curative effect of conjoint fascial sheath suspension and the simple frontalis muscle suspension for moderate or severe ptosis.METHODS:In March 2013 to March 2016 in our hospital, 46 patients with moderately severe ptosis(68 eyes) were taken as the research objects.According to random number table method, they were divided into study group and the control group, 23 cases in each group.Study group(34 eyes) received the joint fascial sheath suspension (CFS), the control group(34 eyes) received frontalis muscle suspension.The degree of ptosis correction, upper eyelid retracted, satisfaction and complications of two groups were compared.RESULTS:The corrected rate of the treatment group was higher than that of the control group, the difference was statistically significant (P<0.05).After treatment, the upper eyelid retracted of the study group was significantly lower than that of the control group, the difference was statistically significant (P<0.05).The satisfaction of the treatment group was higher than that of the control group, the difference was statistically significant (P<0.05).The incidence of complications in the study group was significantly less than that in the control group, and the difference was statistically significant (P<0.05).CONCLUSION:Conjoint fascial sheath suspension is more effective on the treatment of severe ptosis than the simple frontalis muscle suspension, and has advantages such as less trauma, repeatable, and less complication.

Objective To apply the problem-based learning (PBL) based on the web in the rehabilitation therapy teaching. Methods The 64 students of rehabilitation therapy in grade 2009 and 2010 were taught with selected 3 chapters of physiology, using traditional teaching and PBL based on the web respectively. They were investigated through questionnaire after learning. Results Compared with he traditional teaching, PBL based on the web could improve the interesting of learning, self-study ability, and scope of knowledge. Conclusion PBL based on the web could improve the quality of physiology teaching for students of rehabilitation therapy.

Mesenchymal stem cells (MSCs) are multipotent stromal cells derived from the mesoderm that can differentiate into a variety of cell types.Recently,as the study of MSCs in the treatment of various autoimmune diseases is maturing,more and more researchers have advocated the immune function of MSCs and the treatment for dry eye.The rate of dry eye is higher.The duration of therapy in dry eye,especially immune related dry eye,is long,and the therapeutic effect is poor.Dry eye has affected people's quality of life,so it is important to find new methods to treat it.This article reviews MSCs function in dry eye.

Objective To evaluate the repeatability and agreement of two optical biometers (Lenstar LS900 (R) and SW-9000) for ocular biometry in Chinese adolescents.Methods A prospective study was conducted which included 65 ametropic patients,with an average age of (11.45 ± 2.67) years (age ranging from 8 to 18 years).The ocular biometry for right eyeball was performed with Lenstar LS900 (R) and SW-9000 respectively,followed by evaluation of the repeatability of the two biometers using one-way analysis of variance,and the agreement of the two instruments using the Bland-Altman plot.Results The repeatability of parameters measured by Lenstar LS900 (R),including axial length (AL),K value in the flattest meridian (K1),K value in the steepest meridian (K2),central corneal thickness (CCT),anterior depth (AD),lens thickness (LT),pupil diameter (PD),was well,and all intraclass correlation coefficient (ICC) ＞ 0.9;the repeatability of white to white (WTW) was inferior to other parameters,but it was still ＞0.88.The repeatability of AL,K1,K2,CCT measured by SW-9000 was good,with their ICC ＞ 0.9,but the repeatability of other parameters was poor.The parameters with good repeatability including AL,K1,K2,CCT measured by SW-9000 and Lenstar LS900 (R) were compared respectively,and the results showed that AL and CCT examined by SW-9000 were slightly longer than those measured by Lenstar LS900 (R),and the difference was statistically significant (all P ＜ 0.05).However,there was no significant difference about K1,K2 (all P＞0.05).Moreover,the AL,K1,K2 and CCT measured by the two instruments had close linear correlation (all r ＞0.97,all P ＜0.01).The BlandAltman plot showed that 95％ LoA (limits of agreement) of AL was (-0.057 to 0.133) mm,K1 was (-0.456 to 0.369) D,K2 was (-0.388 to 0.549) D and CCT was (-3.483 to 8.016) μm.Conclusion Biometric parameters including AL,K1,K2,CCT measured by Lenstar LS900 (R) and SW-9000 have good repeatability in the adolescents aged 8-18 years and they are highly correlated;meanwhile,the agreement of AL,K1,K2,CCT measured by SW-9000 with Lenstar LS900 (R) is acceptable in clinical practices.

Salinity is the main limitation factor for plant growth and crop production.Many approaches to enhance plant resistance to salinity by genetic engineering have been developed.Over-expressions of salt-tolerance related genes encoding proteins involved in signal transduction pathways,ion channels and compatible solutes synthesis for the stabilization of biological structures under salinity stress are the most often used strategies.The recent progresses in genetic engineering to improve salt tolerance in plants and the possible problems in researches was reviewed.
