ABSTRACT
Objective:To evaluate the clinical effect of Jiedu-Shengji Decoction combined with Maren soft capsule in the treatment of postoperative pain and edema of mixed hemorrhoids. Methods:110 patients with circular mixed hemorrhoids in the People's Hospitalof Lujiang County from January 2017 to January 2019 who met the inclusion criteria were divided into two groups according to the random number table method, with 55 patients in each group. Both groups were treated with external dissection and internal ligation operation of mixed hemorrhoids. The control group was treated with Maren soft capsule after the operation. The study group was treated with atomization fumigation and washing of Jiedu-Shengji Decoction on the basis of the control group. Both groups were treated for 14 days. VAS was used to evaluate the degree of anal pain. The anal edema was observed and graded. Serum levels of VEGF, basic fibroblast growth factor (bFGF) and platelet-derived growth factor (PDGF) were measured by ELISA. 14 days after the operation, to observe and evaluate the complications, the clinical effect was evaluated. Results:The total effective rate of the study group was 92.7% (51/55), and that of the control group was 74.6% (41/55), the difference was statistically significant ( χ2=6.643, P<0.01). The VAS score and anal edema score of the study group on the 7 d ( t values were 9.144 and 8.541, respectively, all Ps<0.01) and 14 d ( t values were 13.720 and 12.819, respectively, all Ps<0.01) after operation were significantly lower than those of the control group. The level of VEGF, bFGF and PDGF in the study group on the 7 d ( t values were 7.491, 2.972 and 5.170, respectively, all Ps<0.01) and 14 d ( t values were 6.117, 3.031 and 4.599, respectively, all Ps<0.01) after operation were significantly higher than those in the control group. The incidence of postoperative complications was 7.3% (4/55) in the study group and 3.6% (2/55) in the control group, there was no significant difference between the two groups ( χ2=0.705, P=0.401). Conclusions:The clinical effect of atomization fumigation and washing of Jiedu-Shengji Decoction combined with Maren soft capsule in the treatment of postoperative pain and edema of mixed hemorrhoids is significant, which can significantly improve symptoms, accelerate the formation of new blood vessels, promote wound healing, and have fewer complications.
ABSTRACT
Objective:To investigate the role of peptidyl arginine deiminase 4 (PAD4) in anti-β 2GP1/β 2GP1 complex-induced formation of neutrophil extracellular trapping networks (NETs). Methods:Peripheral blood neutrophils were isolated from healthy humans by density gradient centrifugation. PAD4 expression was detected by Western blot after the neutrophils were incubated with anti-β 2GP1/β 2GP1 complex (100 μg/ml) for a certain period of time. PAD4 inhibitor Cl-amidine (10 μmol/L) was used to pretreat neutrophils. Changes in the expression of citrullinated histone 3 (CitH3) at protein level and the relative content of myeloperoxidase (MPO)-DNA were detected by Western blot and ELISA, respectively. A mouse thrombus model of antiphospholipid syndrome (APS) was established by inferior vena cava stenosis. Intervention experiments were performed by intraperitoneal injection of Cl-amidine (50 mg/kg). The expression of CitH3 at protein level in plasma was detected by Western blot. The concentration of circulating free DNA (cf-DNA) in plasma was measured with fluorescent staining. Thrombus in inferior vena cava was collected and weighted to evaluate whether inhibiting the activity of PAD4 would suppress the APS-IgG-induced formation of NETs and thrombosis. Differences among groups were analyzed by t test or one-way analysis of variance (ANOVA). Results:The expression of PAD4 induced by anti-β 2GP1/β 2GP1 complex was significantly down-regulated in the cytoplasm, but increased in the nucleus [(3.67±0.32) vs (1.47±0.19), t=10.22, P<0.05; (0.57±0.19) vs (2.97±0.31), t=11.49, P<0.05]. Cl-amidine significantly inhibited the anti-β 2GP1/β 2GP1 complex-induced expression of CitH3 protein by neutrophils [(2.46±0.47) vs (0.46±0.13), t=12.24, P<0.01], and reduced the MPO-DNA content in the culture supernatants [(4.09±0.94) vs (2.80±0.57), t=4.23, P<0.05]. In vivo, Cl-amidine significantly inhibited the expression of CitH3 protein [(3.97±0.56) vs (1.09±0.45), t=11.83, P<0.01] and decreased the content of cf-DNA [(2 685.0±735.8) vs (1 784.0±577.0), t=3.93, P<0.05] in plasma of APS mice. Compared with the experimental APS mice in the control group, the weight of thrombus in the APS mice pretreated with Cl-amidine was significantly reduced [(8.22±3.06) vs (4.89±1.90), t=2.27, P<0.05]. Conclusions:PAD4 was involved in the formation of NETs induced by anti-β 2GP1/β 2GP1 complex, which might play an important role in APS thrombosis.

ABSTRACT
Objective@#To investigate the effects of anti-β2 glycoprotein Ⅰ(β2GPⅠ) antibody on atherosclerosis in ApoE deficient mice.@*Methods@#A total of 24 male ApoE deficient mice of specific pathogen free level(six to eight-week old)were divided into normal control group, high fat diet group, high fat diet with anti-β2GPⅠ group, high fat diet with homologous control antibody group (n=6 each group). During the feeding period, mice were weighed every 2 weeks and were intraperitoneally injected with anti-β2GPⅠIgG (100 μg/per) and homologous control IgG (100 μg/per) according to grouping once a week. At the 16th week, the carotid arterial lipid deposition was observed by small animal magnetic resonance imaging, and blood samples were collected from internal vein of eyeball and the concentrations of TC, TG, HDL-C and LDL-C in plasma were measured after EDTA anticoagulant treatment. AI was calculated. The mice were then sacrificed and carotid arteries were removed, hematoxylin-eosin staining was used to observe the atherosclerotic lesions near the bifurcation of carotid artery and to calculate lesion size.@*Results@#(1) The body weight of mice was significantly higher in the high fat diet group compared to other 3 groups(all P<0.05), which was similar among high fat diet+ anti-β2GPⅠantibody group, high fat diet+ homologous control IgG group and normal diet control group (P>0.05). (2) After 16 weeks, plasma concentrations of TC and LDL-C in high fat diet group, high fat diet+ anti-β2GPⅠantibody group and high fat diet+ homologous control IgG group were significantly higher than in normal diet group (all P<0.05), there was no significant difference among high fat diet groups. The level of HDL-C was significantly higher in high fat diet control group than in normal diet control group. The concentration of TG was similar among groups. However, the value of AI in high fat+ anti-β2GPⅠ antibody group was significantly higher than in other groups (all P<0.05). (3) After 16 weeks, magnetic resonance imaging revealed that mice in high fat diet+ anti-β2GPⅠ antibody group had more obviously lipid deposition in the carotid arteries, it was significantly higher than that in the other groups, and the cross sections of carotid arteries stained with HE also demonstrated obviously carotid lumen stenosis and the percentage of carotid plaque area to carotid artery was (37.545±1.351)% in the high fat diet+ anti-β2GPⅠ antibody group, it was significantly higher than normal diet group ((1.235±0.460)%), high fat diet control group((11.635±2.751)%) and high fat diet+ homologous control IgG group ((11.815±2.623)%), all P<0.01. In high fat diet+ anti-β2GPⅠ antibody group, the area of carotid plaque was (3.121±0.124)×104 μm2, it was also significantly higher than normal diet group ((0.094±0.015)×104 μm2), high fat diet control group ((1.309±0.147)×104 μm2) and high fat diet+ homologous control IgG group ((1.027±0.228)×104μm2), all P<0.01.@*Conclusion@#Anti-β2GPⅠ antibody can promote atherosclerotic plaque formation in high fat diet fed ApoE deficient mice.
