ABSTRACT
Objective To explore the effect of traditional incision and drainage combined with vacuum sealing drainage (VSD)in treating patients with purulent exudation-staged genual septic arthritis. Methods The patients with purulent exuda-tion-staged genual septic arthritis were selected in the Zhengzhou Orthopedics Hospital from January 2010 to December 2015, and they were divided into control group and observation group. Fifty-four patients in the control group were treated with open operative drainage,while fifty patients in the observation group were treated with open operative drainage combined with VSD. The operation time,intraoperative bleeding volume,tourniquet application time,washing time,antibiotic use time,hospitalization time,therapeutic effect and relapse rate were compared between the two groups. Results There was no statistical difference in operation time and tourniquet application time and intraoperative bleeding volume between the two groups(t = - 0. 216,2. 518, 11. 320;P > 0. 05). Compared with the control group,the antibiotic use time and hospitalization time were shorter,the washing time was longer in the observation group(t = 2. 270,- 46. 310,2. 518;P < 0. 05). The occurrence rate of postoperative compli-cations in the control group and the observation group was 9. 3%(5 / 54)and 6. 0%(3 / 50),there was no statistical difference in the occurrence rate of postoperative complications between the two groups(χ2 = 0. 331,P > 0. 05). The fineness rate in the control group and the observation group was 25. 9%(14 / 54)and 22. 0%(11 / 50),there was no statistical difference in the fineness rate between the two groups(χ2 = 0. 219,P > 0. 05). The relapse rate in the control group and the observation group was 33. 3%(18 / 54)and 8. 0%(4 / 50),the relapse rate in the observation group was lower than that in the control group (χ2 =0. 331,P <0. 05). Conclusion Traitional incision and drainage combined with VSD has advantages of shortening hospital-ization and intravenous antibiotic time and decreasing relapse rate in treating purulent exudation-staged genual septic arthritis.
ABSTRACT
The inflammatory response is involved in the pathogenesis of the most common types of heart disease.Sanguinarine (SAN) has various pharmacological properties such as anti-inflammatory,antioxidant,antibacterial,antitumor,and immune-enhancing properties.However,few studies have investigated the effects of SAN on lipopolysaccharide (LPS)-induced inflammatory and apoptotic responses in H9c2 cardiomyocytes.Therefore,in this study,H9c2 cells were co-treated with SAN and LPS,and the mRNA levels of pro-inflammation markers and the apoptosis rate were measured to clarify the effect of SAN on cardiac inflammation.The underlying mechanism was further investigated by detecting the activation of Toll-like receptor (TLR)4/nuclear factor-κB (NF-κB) signaling pathways.As a result,increased mRNA expression of interleukin (IL)-1 β,IL-6,and TNFα induced by LPS was attenuated after SAN treatment;LPS-induced apoptosis of H9c2 cardiomyocytes and cleaved-caspase 8,9,3 were all significantly reduced by SAN.Further experiments showed that the beneficial effect of SAN on blocking the inflammation and apoptosis of H9c2 cardiomyocytes induced by LPS was associated with suppression of the TLR4/NF-κB signaling pathway.It was suggested that SAN suppressed the LPS-induced inflammation and apoptosis of H9c2 cardiomyocytes,which may be mediated by inhibition of the TLR4/NF-κB signaling pathway.Thus,SAN may be a feasible therapy to treat sepsis patients with cardiac dysfunction.

ABSTRACT
OBJECTIVE@#To observe the effect on the inhibition of coronary atherosclerosis hardening of the paraoxonase gene (PON-1) which transfected to the rabbit epicardial adipose tissue.@*METHODS@#Rabbit coronary atherosclerosis model was established by high-fat feeding, liposome-encapsulated recombinant plasmid pEGFP-PON-1 50 μ L was injected to the rabbit pericardial cavity, and was harvested 4 weeks after transfection.@*RESULTS@#The epicardial fat transfected PON-1 gene had effect on the high lipid level. It significantly increased expression of PON-1 in peripheral arterial vascular tissue (P <0.05); and significantly reduced total cholesterol and low-density lipoprotein cholesterol levels (P<0.05), and the thickness ratio of coronary artery intima/media (P <0.05).@*CONCLUSIONS@#The injection of the PON-1 gene in the pericardial cavity can effectively suppress the formation of coronary atherosclerosis.
