Clinical study on Chuanxiong Hualiu Mixture in the treatment of blood stasis and phlegm stagnation type of ovarian cyst

Objective:To observe the clinical efficacy of Chuanxiong Hualiu Mixture in the treatment of blood stasis and phlegm stagnation type of ovarian cyst and the effects on physical and chemical indicators.Methods: A total of 80 patients with blood stasis and phlegm stagnation type of ovarian cyst were randomly divided into two groups, research group (n=40) took Chuanxiong Hualiu Mixture, control group (n=40) took Guizhi Fuling Capsule, 3 months was a course of treatment, and the curative effect was compared between two groups.Results:(1) The overall response rate of Chuanxiong Hualiu mixture group after 3 months of treatment was 82.5%, that of Guizhi Fuling Capsule group was 62.5%, the overall response rate of Chuanxiong Hualiu mixture group was higher than that of control group, and the difference was statistically significant;(2) before and after treatment, sex hormone and hemorheology index E2 of both groups decreased significantly, whole blood viscosity, whole blood reduced viscosity and plasma viscosity decreased significantly, the results were statistically significant, but there was no difference between two groups;(3) rank sum test of TCM symptom efficacy between two groups before and after treatment showed that the overall response rate of Chuanxiong Hualiu mixture group was 95%, the overall response rate of Guizhi Fuling Capsule group was 85%, the overall response rate of research group was better than that of control group, and the difference was statistically significant.Conclusion:Chuanxiong Hualiu mixture has good curative effect for the treatment of ovarian cyst, it can effectively improve the patients' blood stasis and phlegm stagnation constitution, and its mechanism of action is associated with lowering estrogen levels and improving hemorrheology.

Stability of NiCrAlY coating/titanium alloy system under pure thermal exposure

In this paper,NiCrAlY coating was deposited on TC4 titanium alloy using arc ion plating,and the stability of NiCrAlY coating/TC4 substrate system under pure thermal exposure was analyzed in a wide temperature range.During the thermal exposure,β→γ′→γphase transformation takes place in the NiCrAlY coating.The NiCrAlY coating phases totally decompose above the allotropic transformation temperature of TC4.The allotropic transformation ofα-Ti to β-Ti of the substrate significantly influences the stability of NiCrAlY coating/TC4 substrate system.NiCrAlY coating elements are mainly consumed by interfacial reactions below the allotropic transformation temperature of TC4.Above the allotropic transformation temperature of TC4,NiCrAlY coating elements are mainly consumed by element dissolution in β-Ti.The NiCrAlY coating totally degrades for the dissolution of coating elements in the substrate to form thickβ-Ti stabilized layer.
