To evaluate the influence of phacoemulsification on corneal endothelium of senile cataract with lupus nephritis (LN).
●METHODS:This clinical trial involved 40 cataract patients with lupus nephritis (40 eyes), and 50 cases (50 eyes) without lupus nephritis. All of them underwent phacoemulsification+lOL implantation. The parameters of corneal endothelial cell including central corneal endothelium cell density ( CED ), average area of endothelial cell ( AVE) and coefficient of variation ( CV) were recorded by corneal endothelial microscope pre -operation and at one month after operation. The data were analyzed by SPSS 13. 0 statistical software.
● RESULTS: Both LN group and control group, the morphology of coneal endothelial was statistical significant differences between pre - operation and 1mo postoperation. The CED was lower, AVE and CV were higher ( P < 0. 05, respectively). A significant decrease in CED was seen in the LN group than did in the control group (P < 0. 05). Compared to control group,the post -operative AVE and CV in LN group was significantly increased (P<0. 05).
● CONCLUSlON: The corneal endothelial cell in lupus nephritis patients is more fragile. Safe and reliable operation should be selected for these patients.

The effects of Guizhi Fuling capsule and its active ingredient combination within different concentration on SPL proliferate were observed by MTT method. The ratio of CD80/86, CD3CD25 and CD3CD69 was used to evaluate cell activation effects of Guizhi Fuling capsule and its active ingredient combination by FCM. Guizhi Fuling capsule with concentration of 400 mg · L(-1)can promote spleen lymphocyte proliferation, as well as the active ingredient combination, which showed the obvious dose-effect relationship. Compared with control group, the difference has statistical significance (P≤0.01). The result of FCM showed that Guizhi Fuling capsule and its active ingredient combination can promote CD80 and CD86 expression on spleen lymphocyte, and also can increase CD25 and CD69 ratio between spleen CD3+ cells. Compared with control group, the difference has statistical significance (P≤0.01). Thus, Guizhi Fuling capsule and its active ingredient combination may have immune-modulate effects, and the mechanism may have a close relationship with the lymphocyte activation.

Chinese Journal of Tissue Engineering Research 2018;22(15):2421-2426
BACKGROUND: There are a variety of methods for establishing periprosthetic osteolysis animal model, and the models established by different methods and with different animals have their own characteristics.OBJECTIVE: To review the research profiles of the periprosthetic osteolysis and the characteristics of the various models, and to provide a reference for the related research. METHODS: The relevant articles on the periprosthetic osteolysis animal models were searched in PubMed from January 1999 to May 2017, with the key words of "animal model, osteolysis" in English by the computer. Similarly, Chinese Journal Full-text Database was retrieved for related articles published from January 1999 to May 2017, with the key words of "animal model, osteolysis" in Chinese. Articles that were unrelated to the periprosthetic osteolysis animal model were excluded. Classic and recently published articles were selected. RESULTS AND CONCLUSION: (1) The artificial induced animal models are the principal means to establish animal models of periprosthetic osteolysis and they have been widely used in the study of periprosthetic osteolysis pathogenesis, pathological process and treatment. (2) Small-animal models present many advantages: inexpensive to purchase, high physiological turnover, controlled source, homogenous and established genetic background. However, a limitation of these small-animal models is that the temporal pattern of osteolysis is different from the long-term osteolysis that occurs in patients. (3) The large animal model is more similar to the bone dissolution process around the human prosthesis, but the cost is high; the breeding is difficult; the operation requirement is hard. Thus, its widespread use is limited. (4) Furthermore, innovative models that combine the advantages of both are also constantly explored. Overall, the selection of models should be based on research conditions and needs to be considered.
