Objective:To investigate the effect of astragaloside Ⅳ on the apoptosis of thyroid cells in Hashimoto's thyroiditis(HT)rats and Ras homolog gene family member A(RhoA)/Rho-associated coiled-coil containing kinase 2(ROCK2)pathway.Methods:The HT rat model was induced by subcutaneous injection of thyroglobulin combined with high iodine drinking water and randomly divided into model group,astragaloside(80 mg/kg)group,Rhosin(RhoA inhibitor,40 mg/kg)group,astragaloside Ⅳ(80 mg/kg)+ Rhosin(40 mg/kg)group(12 rats in each group),another 12 SD rats were selected and drank water normally and injected the same dose of saline subcutaneously as control group.After the drugs were grouped and processed,the serum anti-thyroglobulin antibody(TGAb),anti-thyroid peroxidase antibody(TPOAb)levels and the inflammatory factors IL-6,IL-17,IL-1β contents were measured by ELISA kits;the pathological changes of thyroid tissue in each group were detected by hematoxylin-eosin(HE)staining;the apopto-sis rate of rat thyroid cells in each group were detected by TUNEL staining;the expressions of RhoA/ROCK2 pathway proteins in thy-roid tissues of rats in each group were detected by Western blot.Results:Compared with the control group,the thyroid follicles in the model group had abnormal structure,some atrophy or disappearance,disordered arrangement,surrounding inflammatory cell infiltra-tion,and obvious pathological damage to the thyroid tissue,the serum TGAb,TPOAb,IL-6,IL-17 and IL-1β levels,thyroid cell apoptosis rate,and thyroid tissue RhoA and ROCK2 protein expression levels were significantly increased(P<0.05);compared with model group,the pathological damage of the thyroid tissue of rats in the drug intervention group were reduced,the serum TGAb,TPOAb,IL-6,IL-17 and IL-1β levels,thyroid cell apoptosis rate,and thyroid tissue RhoA and ROCK2 protein expression levels were decreased(P<0.05);compared with astragaloside Ⅳ group and the Rhosin group respectively,the pathological damage of the thyroid tissue of rats in the astragaloside Ⅳ+Rhosin group were further reduced,the serum TGAb,TPOAb,IL-6,IL-17 and IL-1β levels,thyroid cell apoptosis rate,thyroid tissue RhoA and ROCK2 protein expression levels were decreased(P<0.05).Conclusion:Astragaloside Ⅳ may down-regulate the expression of RhoA/ROCK2 pathway to reduce the inflammatory injury of thyroid tissue,inhib-it thyroid cell apoptosis,and improve the symptoms of HT in rats.

Objective@#To explore the changes and clinical significance of serum prolactin and estrogen levels in women with autoimmune thyroid diseases.@*Methods@#From January 2018 to December 2018, 76 newly diagnosed female patients with autoimmune thyroid diseasein outpatient and inpatient clinics of the People's Hospital of Hebei Province were selected as study group, including 40 cases of Graves' disease and 36 cases of hashimoto's thyroiditis.And 60 healthy women with age matched were selected as control group.Serum estrogen, prolactin, thyroid hormone and their antibodies, IL-2, IL-6, IL-10 and other related indicators were determined before and after treatment, and the correlation analysis was performed.@*Results@#The levels of estrogen[(302.85±78.62)ng/L], prolactin [(15.98±4.18)μg/L], IL-2 [(224.45±61.28)ng/L], IL-6 [(211.46±67.25)ng/L] in the study group were all higher than those in the control group [(228.4±71.38)ng/L, (10.35±3.21)μg/L, (120.34±38.27)ng/L, (165.51±50.09)ng/L], and the IL-10 level in the study group was lower than that in the control group [study group: (15.65±4.86)ng/L; control group: (20.12±4.83)ng/L] , there were statistically significant difference between the two groups(t=5.78, 3.11, 8.98, 3.94, all P<0.05). After treatment, the levels of estrogen [(237.11±70.42)ng/L], prolactin[(10.40±3.32)μg/L], IL-2[(122.67±38.99)ng/L], IL-6[(166.24±52.09)ng/L] in the study group were significantly decreased compared with before treatment(t=5.56, 3.76, 9.04, 4.02, all P<0.05), and the IL-10 level [(19.96±4.93)ng/L] was significantly increased (t=3.95, P<0.05). However, there was no statistically significant difference in thyroid antibody between the two groups (P>0.05). Estrogen level was positively correlated with prolactin, IL-2 and IL-6(r=0.327, 0.298, 0.336, all P<0.01), and negatively correlated with IL-10(r=-0.285, P<0.05).@*Conclusion@#Elevated levels of estrogen and prolactin can stimulate the production and release of inflammatory cytokines, thus affecting the level of thyroid hormone, which is closely related to the female autoimmune thyroid disease.

Objective To study the changes and the role of MCP -1,IL -8,VEGF,NO,NOS in the T2DM patients with different types of CHD.Methods According to the result of coronary arteriongraphy and clinical symp-toms,and the diagnostic code of T2DM established by Chinese Medical Association diabetology branch in 2007, 126 patients of T2DMwith CHD were chosen and divided into two groups:ACS +T2DM group (A group,74 cases) and SAP +T2DMgroup (B group,52 cases),in addition,50 healthy people were chosen as control group.The levels of MCP -1,IL -8,VEGF were measured by the method of ELISA.The level of NO was measured by the method of nitrate reductase and NOS activity was measured by the method of spectrophotometer.Then,the results were analyzed. Results The levels of MCP -1 and IL -8 in A group and B group were[(115.98 ±39.57)pg/mL,(98.76 ± 31.55)pg/mL],[(131.22 ±42.83)pg/mL,(115.75 ±40.37)pg/mL],which were all higher than those in group C [(75.63 ±23.69)pg/mL,(68.53 ±37.85)pg/mL,t =4.12,2.26,3.78,2.21,all P 0.05). MCP -1 was positively correlated with Il -8,VEGF (r =0.35,0.33,all P <0.01),and it had negative correlation with NO (r =-0.24,P <0.05).Conclusion Inflammatory factor and oxidative stress both participate in the T2DM with different types of CHD,it relates with the degree of CHD.

Objective: To observe the clinical effect of midnight-noon ebb-flow day-prescription of acupoints on biliary colic. Methods: 60 cases with biliary colic were randomized into two groups, 30 cases in each group. Day-prescription of five transport points was employed in the treatment group, while point selection based on pattern identification was employed in the control group. Results: The pain-killing rates between the two groups had no statistical differences (P>0.05). Conclusion: Day-prescription of acupoints can obtain similar pain-killing effect with point selection based on pattern identification, but with less points and treatments.
