ABSTRACT
Objective To investigate the effect of tripterygium glycosides combined with recombinant human tumor necrosis factor receptor Ⅱ antibody fusion protein for injection on serum vascular endothelial growth factor (VEGF),rheumatoid factor (RF),receptor activator of nuclear factor κ B ligand (RANKL) levels in patients with rheumatoid arthritis.To provide reference for rational clinical application.Methods From December 2014 to January 2016,132 patients with rheumatoid arthritis were divided into observation group and control group by random number table method,,with 66 cases in each group,The control group was treated with tripterygium glycosides alone (10 mg each time,3 times daily,orally) for 3 months.The observation group was treated with a combination of tripterygium glycosides and recombinant human tumor necrosis factor receptor Ⅱ (0.4 mg/kg,once weekly,hypodermic injection) for 3 months.The clinical efficacy,and serum VEGF,RF and RANKL levels were compared between 2 groups.Results The effective rate of the observation group was 92.4％ (61/66),which was significantly higher than that in the control group (80.3％,53/66).There was a significant difference between the two groups (x2=4.117,P＜0.05).There was no significant difference in the levels of serum VEGF,RF and RANKL between the two groups (t =0.174,0.103,0.359,all P＞0.05).After treatment,the levels of serum VEGF,RF and RANKL in the observation group and the control group were (20.8± 11.5) ng/L and (27.3 ±13.1) ng/L,(258.4±54.5) U/L and (298.1 ±49.5) U/L,(0.083±0.021) pmol/L and (0.197 ± ±0.064),respectively.There were significant differences between the two groups (t =3.029,4.381,13.750,all P＜0.05).The incidence rate of adverse reactions in the control group was 10.5％ (7/66),which was significantly higher than that in the observation group (1.5％,1/66).There was a significant difference between the two groups(x2 =4.790,P＜0.05).The one-year recurrence rate was 25.0％ (13/52) in the control group and that was 6.7％ (4/60) in the observation group,respectively,and there was a significant difference between the two groups (x2 =7.272,P＜ 0.05).Conclusion Tripterygium glycosidescombined with recombinant human tumor necrosis factor receptor Ⅱ antibody fusion protein for injection is effective in the treatment of rheumatoid arthritis,which reduces the levels of serum VEGF,RF and RANKL,and has a low incidence of adverse reactions and recurrence.
ABSTRACT
Objective To observe the structure of the mud hull packed Oncomelania eggs and the surface structure of colloid membrane called the third grade membrane of eggs. \ Methods\ Scanning electron microscopy was used to observe Oncomelania snail eggs with integral mud hull collected from eastern Dongting Lake. \ Results and Conclusion\ The mud hull of eggs was made of unshapen small humification combined with earth granules with a diameter of 2^6-9^2 ?m. The mud hull in 60um thickness was honeycomb-like in shape with many small holes and small folds on the wall. There were many round or irregularly round hollownesses on the inner layer of mud hull that contacts colloid membrane but no hole through mud hull. There were some protein fiber networks covering on the colloid membrane and apophysis. The structure of the mud hull showed that the exchange of matter was maintained between eggs and outside, and the mud hull is of great importance to regulating temperature and moisture for the growth of eggs by preventing hydrosoluble substances from penetrating into eggs. The protein fiber networks act on gluing mud hull and buffering outside power. The dense glue membrane might be a main barricade to prevent \{pharmaceutical\} molecules from penetrating into eggs.
