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.

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 establish and identify HPLC fingerprints of Panacis Japonici Rhizoma from different regions, and provide a scientific method for quality its control and standardization. Methods The fingerprints of Panacis Japonici Rhizoma were established based on HPLC method. The similarity evaluation, cluster analysis (CA), and principal component analysis (PCA) were applied for the experimental data, in order to find out the similarities and differences among the 10 batches of Panacis Japonici Rhizoma from different regions. Meanwhile, the qualitatively and quantitatively analyze were adopted in the common peaks of Panacis Japonici Rhizoma by total statistical moment method. Results The HPLC fingerprint with 16 common peaks was established, for the common chemical components, six were identified as ginsenoside Rg1, ginsenoside Re, ginsenoside Rb1, chikusetsusaponin V, chikusetsusaponin IV, and chikusetsusaponin IVa, respectively. Among them, the contents of chikusetsusaponin V and IV in different batches of Panacis JaponiciRhizoma samples showed little differences. The similarities of samples from various regions except S7 were over 0.90. The samples were classified into three categories by CA and PCA methods. The parameters of total statistical moment for five species of Panax genus showed significantly differences. Conclusion The developed HPLC fingerprint of Panacis Japonici Rhizoma combined with chemical pattern recognition can provide a scientific instruction for the quality control of Panacis Japonici Rhizoma and the differentiation of five herb medicines from Panax genus.

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.

Textbook is the embodiment of teaching content and teaching method.Stereoscopic teaching materials construction is the key of making good education reform and increasing teaching quality and one of the most important constructions in medical colleges and universities.Taking the features of physiology into consideration,this paper elaborated the contents of stereoscopic teaching materials and discussed some advantage of teaching material construction.

Mesenchymal stem cells (MSCs) have good immune regulatory function,can inhibit many immune cell proliferation,direct effects on activation and proliferation of T cell,play a role in immune regulation by Treg cells or by the secretion of soluble factors regulating Thl/Th2 secretion and reaction equilibrium,inhibit the inflammation through the anti-inflammatory,regulation of cytokines expression at the same time,so reduce the expression levels of matrix metalloproteinase-2 and-9,which may promote lacrimal gland tissue damage,and thus play a role in immune regulation.MSCs can reduce the autoimmune dry eye clinical index,recovery secretion function of part lacrimal gland.This article reviews the research advances in inmmmne regulation of MSCs on autoimmune dry eye.
