Objective To discuss the relationship between TCM syndromes and peritoneal fluid cytokine IL-6, IL-8 and TNF-α of endometriosis infertility patients, and provide thoughts for clinical treatment. Methods Totally 105 patients of endometriosis infertility were differentiated to six syndrome groups, including kidney deficiency and blood stasis, qi stagnation and blood stasis, heat stagnation and blood stasis, cold congelation and blood stasis, qi deficiency and blood stasis, phlegm-dampness stagnation. Thirty patients of non-endometriosis infertility were selected as control group. Enzyme-linked immunosorbent assay was used to detect cytokine levels of IL-6, IL-8 and TNF-α. Results In 105 cases of EM infertility, 35 cases (33.33%) were syndrome of kidney deficiency and blood stasis, 22 cases (20.95%) were syndrome of cold congelation and blood stasis, 18 cases (17.14%) were syndrome of qi stagnation and blood stasis, 10 cases (9.52%) were syndrome of heat stagnation and blood stasis, 11 cases (10.48%) were syndrome of qi deficiency and blood stasis, 9 cases (8.57%) were phlegm-dampness stagnation syndrome. The levels of IL-6, IL-8 and TNF-αin each syndrome group of EM infertility were higher than control group (P<0.01). IL-6 level in kidney deficiency and blood stasis group were higher than other syndrome groups (P<0.05). The levels of IL-8 and TNF-α in kidney deficiency and blood stasis group, and heat stagnation and blood stasis group were higher than other syndrome groups (P<0.05). IL-8 in kidney deficiency and blood stasis group was higher than that in heat stagnation and blood stasis group (P<0.05). Conclusion TCM syndromes in patients with endometriosis infertility have some relevance with peritoneal fluid cytokine levels of IL-6, IL-8, TNF-α, which may guide clinical understanding and treatment of endometriosis infertility.

Objective To explore the changes and significance of Klotho protein levels in different stages of chronic kidney disease (CKD). Methods From March 2015 to December 2017,176 patients with CKD admitted to nephrology department of Inner Mongolia People＇s Hospital were selected as the study object (CKD group), and 80 healthy patients in our hospital were selected as the control group in the same period. The serum Klotho levels of CKD patients and control group at different stages were detected by double antibody sandwich ELISA, and the differences between each group were compared. Results The serum Klotho level of CKD group (( 4. 84 ± 1. 87) μg／L) was significantly lower than that of the control group ((9. 11± 3. 14) μg／L) ( t＝ 13. 82, P＜0. 01) . One-way anova showed that estimated renal glomerular filtration rate (eGFR),serum albumin (ALB),hemoglobin ( Hb),blood calcium ( Ca) and serum Klotho were gradually decreased,while phosphorus (P) and creatinine (Cr) in serum were gradually increased,and the difference was statistically significant among the five stages( all P＜0. 01). Spearman correlation analysis showed that Klotho level was positively correlated with eGFR and Ca,and negatively correlated with CKD stage,Cr and P (r＝0. 369,0. 160,－0. 200,－0. 250,－0. 230,all P＜0. 05). The multiple linear regression equation showed that Klotho level was positively and independently correlated with eGFR ( t＝ 3. 89, P＜0. 001),and negatively correlated with CKD staging independently (t＝－4. 12,P＜0. 001). Conclusion The expression level of serum Klotho protein in patients with CKD is lower than that of healthy people,and it decreases with the increase of CKD stages,which is closely related to the deterioration of renal function. It can be used as a reference index to evaluate the incidence and severity of CKD.
