Background:Our clinical practice of laparoscopic liver resection(LLR)had achieved better short-term and long-term benefits for patients with hepatocellular carcinoma(HCC)over open liver resection(OLR),but the underlying mechanisms are not clear.This study was to find out whether systemic inflammation plays an important role.Methods:A total of 103 patients with early-stage HCC under liver resection were enrolled(LLR group,n=53;OLR group,n=50).The expression of 9 inflammatory cytokines in patients at preoperation,postoperative day 1(POD1)and POD7 was quantified by Luminex Multiplex assay.The relationships of the cytokines and the postoperative outcomes were compared between LLR and OLR.Results:Seven of the circulating cytokines were found to be significantly upregulated on POD1 after LLR or OLR compared to their preoperative levels.Compared to OLR,the POD1 levels of granulocytemacrophage colony-stimulating factor(GM-CSF),interleukin-6(IL-6),IL-8,and monocyte chemoattractant protein-1(MCP-1)in the LLR group were significantly lower.Higher POD1 levels of these cytokines were significantly correlated with longer operative time and higher volume of blood loss during operation.The levels of these cytokines were positively associated with postoperative liver injury,and the length of hospital stay.Importantly,a high level of IL-6 at POD1 was a risk factor for HCC recurrence and poor disease-free survival after liver resection.Conclusions:Significantly lower level of GM-CSF,IL-6,IL-8,and MCP-1 after liver resection represented a milder systemic inflammation which might be an important mechanism to offer better short-term and long-term outcomes in LLR over OLR.

Endocrine Disrupting Chemicals(EDCs)are a group of molecules that can influence hormonal balance,causing disturbance of the reproductive system and other health problems.Despite the efforts to eliminate EDC in the environment,all current approaches are inefficient and expensive.In previous research,studies revealed that laccase-producing microorganisms may be a potential candidate for EDC degradation,as laccases have been found to be able to degrade many kinds of EDCs effectively and steadily.Here,we created two recombinant laccases,each fused with secretion peptide,Novel Signal Peptide 4(NSP4),and expressed them in Escherichia coli(E.coli,BL21),together with one laccase without secretion peptide.We first optimized the culture condition of expressing these laccases.Then,we test the activity of the recombinant laccases of decolorizing of a synthetic dye,indigo carmine.Finally,we confirmed the secreted can degrade one of the EDCs,β-estradiol,showing the potential of using the laccase secretion system to degrade toxic compounds.
