Effects of saline gauze tamponade of calculus bovis sativus in treatment of local tissues of IL-6 and IL-8 in patients with perianal abscess after surgery / 临床外科杂志

Objective To observe the effect of saline gauze tamponade of calculus bovis sativus on the level of IL-6 and IL-8 in the tissue of patients with perianal abscess after operation,and to explore its possible mechanism of action in promoting wound healing.Methods Patients with 84 cases of anal abscess surgery,were randomly divided into treatment group(n=42)and control group(n=42).Treatment group calculus bovis sativus research pressed into powder,take 0.10~0.15g evenly scattered in the saline gauze on the wound packing,the control group was treated with physiological saline gauze wound.After treatment,3,7 and 10d were treated with local granulation tissue about 0.2cm×0.2cm×0.1cm size,the IL-6 and IL-8 cytokines in local tissues were detected by enzyme-linked immunosorbent assay.Results There was no significant difference in the expression of IL-6 and IL-8 between the two groups 3 days after treatment(P>0.05),IL-6 and IL-8 in the treatment group(7,10d)were significantly lower than that in control group,and the difference was statistically significant(P<0.05).Conclusion Calculus bovis sativus in the treatment group,IL-6 and IL-8 levels were significantly lower than those of the control group,indicating that calculus bovis sativus can reduce local inflammation response,promote healing of wound after perianal abscess operation.

Salidroside Promotes Random Skin Flap Survival in Rats by Enhancing Angiogenesis and Inhibiting Apoptosis.

Background Flap necrosis is frequently observed in flap transfer operations. Salidroside has been reported to reduce cell apoptosis by alleviating inflammation and oxidative stress. We investigated the effects of salidroside on the survival of random skin flaps. Materials and Methods The McFarlane flap model was established in 80 rats that were divided into two groups and administered salidroside or saline solution intraperitoneally over 7 days. The area of necrosis and the extent of tissue edema were measured. Angiogenesis was assessed via lead oxide-gelatin angiography, immunohistochemistry for CD34, and VEGF expression. Cell apoptosis was evaluated by expression of cleaved caspase 3, caspase 3, Bax, and Bcl-2. The inflammatory response was evaluated using an ELISA kit for TNF-α and IL-6 in serum. Oxidative stress was assessed by measuring the activity of superoxide dismutase (SOD) and the level of malondialdehyde (MDA). Results Compared with controls, salidroside-treated flaps featured a greater area of surviving tissue and less edema. It also promoted the expression of VEGF and increased skin flap angiogenesis. Cell apoptosis, inflammation reaction, and oxidative stress were significantly attenuated in the salidroside group. Conclusion Salidroside has a positive effect on improving random skin flap survival.

Effects of Muscone on Random Skin Flap Survival in Rats.

BACKGROUND: The necrosis of a distal area of random skin flap remains challenging. Muscone can increase blood flow and reduce ischemia-reperfusion injury, this study was undertaken to investigate the effects of muscone on random skin flap survival. MATERIALS: McFarlane flaps were established in 72 rats and divided into two groups. The test group received intraperitoneal injections of muscone (0.64 mg/kg/d); control rats received intraperitoneal injections of saline. The percentage flap survival area and tissue water content were measured after 7 days. Flap angiogenesis was assessed via lead oxide-gelatin angiography, hematoxylin and eosin staining, and immunohistochemistry and western blotting for vascular endothelial growth factor (VEGF). The extent of apoptosis was evaluated by immunohistochemistry for cleaved caspase 3 and western blotting for cleaved caspase 3, Bax, and Bcl2. Oxidative stress status was assessed by measuring the activity of tissue superoxide dismutase (SOD) and malondialdehyde (MDA) content. RESULTS: Compared with controls, muscone-treated flaps displayed greater survival area lower tissue water content. Muscone increased skin flap angiogenesis and activated VEGF expression. SOD activity and MDA content indicated lower oxidative stress in muscone-treated flaps than controls, and western blotting and immunohistochemistry revealed significantly lower apoptosis. CONCLUSION: Muscone have a positive effect to promote the survival of random skin flap.

Inhibition of autophgay enhances resveratrol-induced apoptosis of human chondrosarcoma cells / 中国病理生理杂志

AIM:Toinvestigatewhetherautophagyisup-regulatedwhenresveratrol(Res)inducesapoptosis in chondrosarcoma , and to study the effects of autophagy inhibitor combined with Res on chondrosarcoma .METHODS:SW1353 cells were divided into 4 groups: control group, Res group, 3-methyladenine (3MA) group, and Res +3MA group.Electron microscopy was used to observe the autophagyosomes in control group and Res group .At the same time, the viability of the cells in the 4 groups was detected by CCK-8 assay.TUNEL staining and Western blotting (for determi-ning the levels of cleaved caspase-3, Bax and Bcl-2) were used to reflect levels of apoptosis in all groups .The expression of autophagy-related proteins Beclin 1, LC3-Ⅱ and p62 was detected by Western blotting .RESULTS: Exposure of the cells to Res resulted in a decrease in cell viability and an increase in the level of apoptosis ( P<0.05 ) .Compared with control group, the level of apoptosis was increased but the autophagy was decreased (P <0.05).Compared with Res group, the cell viability and the level of autophagy were decreased and the level of apoptosis was increased ( P<0.05 ) . CONCLUSION:Resveratrol induces apoptosis and autophagy , and inhibition of autophgay enhances resveratrol-induced apoptosis in chondrosarcoma .

Effects of recombinant human epidermal growth factor on wound healing of perianal abscess after ;operation / 临床外科杂志

Objective To observe the effects of recombinant human epidermal growth factor ( rhEGF)on wound healing of perianal abscess after operation. Methods A total of 112 cases of perianal abscess after operation were randomly divided into the study group( n=56 )and control group( n=56 ). Patients in the control group were disinfected routinely and treated by metronidazole or rivanol. In the stud-y group,patients were treated by rhEGF after disinfection of saline. Wound edema score was evaluated at the 3rd,7th and 10th day after the surgery. Healing time of the wound was recorded simultaneously. Re-sults Wound edema scores in the study group[(1. 20 ± 0. 70),(1. 00 ± 0. 67),and(1. 05 ± 0. 69)] were significantly lower than those of the control group[(1. 70 ± 0. 66),(1. 90 ± 0. 74),and(1. 70 ± 0. 73)]at the 3rd,7th and 10th day after operation(P﹤0. 05). Conclusion rhEGF can promote wound healing obviously.
