Efficacy of morpholinidazole in patients with infection after radical resection of perianal abscess / 中华普通外科杂志

Objective:To observe the clinical efficacy of morpholine nidazole in the treatment of infection after radical resection of perianal abscess.Methods:Thirty patients diagnosed with perianal abscess were randomly divided into the observation group(given intravenous infusion of morpholine nidazole) and the control group(given intravenous infusion of ornidazole).Results:There was no significant difference in postoperative wound infection rate between the observation group and the control group ( P>0.05). There was significant difference in wound healing quality between the two groups on the 2 d and 7 d after the operation ( P<0.05). There was no significant difference in WBC and neutrophil counts between the two groups ( P>0.05), and the WBC and neutrophil counts in the two groups were significantly lower on the 7th day after the operation than before the treatment, and the observation group was significantly lower than the control group ( P<0.05). After treatment, there was no significant difference in the clearance rate of escherichia coli, klebsiella pneumoniae, bacteroides fragile and staphylococcus aureus in the observation group ( P>0.05), but there was significant difference in the overall bacterial clearance rate compared with the control group ( P<0.05). The incidence of adverse reactions in the observation group was significantly lower than that in the control group ( P<0.05). Conclusions:The use of morpholinidazole in patients with perianal abscess is effective and safe.

High salt diet enhances the physical coupling between TRPV4 and cPLA2 / 中国药理学通报

Aim To observe the physical coupling between transient receptor potential channel vanilloid type 4 (TRPV4 ) and cPLA2 in endothelial cells. Methods We investigated the physical association of TRPV4-cPLA2 coupling by immunofluorescence reso-nance energy transfer (immuno-FRET)to assess the spatial proximity between TRPV4 and cPLA2 in human microvascular endothelial cells (HMEC),primary cul-tured endothelial cells and in thoracic aortas rings from high salt-induced hypertension mice.Results At the cellular level,with high salt treatment,the physical in-teraction of TRPV4 and cPLA2 was significantly en-hanced in primary vascular endothelial cells and HMEC.Furthermore, in thoracic aortas rings from high salt-induced hypertension mice,we found an in-creases interaction between TRPV4 and cPLA2 in en-dothelial cells from arterial segments .Conclusion High-salt treatment increases the endothelial TRPV4-cPLA2 coupling,indicating that this coupling may pro-vide a new target for vascular endothelial dysfunction.
