ABSTRACT
Objective:To evaluate clincal value of preoperative peripheral blood CD4/CD8 and neutrophil to lymphocyte ratio (NLR) in papillary thyroid carcinoma (PTC) coexisted with Hashimoto’s thyroiditis (HT) .Methods:Clinicopathological data of 202 patients diagnosed as PTC treated with operation from Jul.2016 to Jun.2019 were retrospectively analyzed. They were divided into Treatment Group including 94 PTC coexisted with HT and Control Group including 108 thyroid cancer according to the postoperateive pathology report. CD4+ and CD8+ subsets in peripheral blood were analyzed by flowcytometer and blood counts were measured before surgery.Results:There was no significant difference in gender, tumor size, number of lesions or lymph node metastasis between the two goups. In comparison with Control Group, median age was lower (39.5 vs 50.5, P=0.001) and CD4/CD8 raito (1.9731.973 Cvs 1.24141973 CD P=0.001) was higher in Treatment group. There was a higher proportion of bilateral lobe thyroidectomy in Treatment Group (40/94 vs 26/108, P=0.005) . A multivariate model analysis identified CD4/CD8 raito as independent risk factor for incidence of PTC coexisted with HT [ OR=0.035, 95% CI (0.009-0.093) , P=0.001]. The NLR level of thyroid cancer patients was correlated with lateral lymph node metastasis negatively (correlation coefficients=-0.286, P=0.045) . Conclusions:PTC might have some connection with HT mediated by body inmune status. Preoperative NLR level is correlated with lateral lymph node metastasis.
ABSTRACT
Objective To evaluate the effects of SHENG JI YU HONG herbs loading on modified gelatin sponges on the wound healing of mechanical trauma.Methods The round size of 1.8cm diameter of full thickness back skin was cut mechanically and covered with petrolatum gauzes,modified gelatin sponges,SHENG JI YU HONG plasters and SHENG JI YU HONG herbs loading on modified gelatin sponges respectively.On day3,day7 and day14 after model mading,the wound surface healing rate,the amount of hydroxyproline,hemoglobin,the number of capillaries and the cells with positive rhVEGF165 by immunochemical method inside granulation of the wound were detected individually.Results On day3,the wound surface healing rate and the number of capillaries and the cells with positive rhVEGF165 of SHENG JI YU HONG herbs loading on modified gelatin sponges were significant enhanced than those in the other groups.On day14,all the experimental indicators of SHENG JI YU HONG herbs loading on modified gelatin sponges were better than those in the other groups with P
