Objective To investigate the protective effect of wound in burn part of wound on nanometer silver dressing.Methods Selected 48 fleet Ⅱ degree and deep Ⅱ degree burn patients of burn deepness equality opposite nonarthrosis place.Two burn wound of deepness equality consistent of the each case were randomly divided in two comparison area.The treatment groups adopted nanometer silver dressing apply.The comparison groups adopted 1%SD-Ag cool frost apply on vaseline gauze.Put up wound secretion germiculture and judged with two groups wound at 3 postburn day(PBD3),PBD5,PBD9 and PBD14.Observed and noted the wound heal instance and speed.Observed the medicament badness responses.Results The wound germ tested rate compare: the masculine rate fleet Ⅱ degree 3.84% and deep Ⅱ degree 9.09% in the treatment groups.The masculine rate fleet Ⅱ degree(11.53)% and deep Ⅱ degree 18.18% in the comparison groups.The wound heal time compare: the treatment groups average shorter two-three days than the comparison groups in the fleet Ⅱ degree.The treatment groups average shorter four-five days than the comparison groups in the deep Ⅱ degree,P

Aim To explore the protective effects and underlying mechanisms of Liu weiwuling Tablets (LW-WL)in concanavalin A (ConA)induced acute immu-nological liver injury in mice.Methods Mice were randomly divided into control,model,Bicyclol,LW-WL low dose (8 g·kg-1 )and LWWL high dose (16 g ·kg-1 )group.The medicattion was performed once daily for seven consecutive days,then the model of im-munological liver injury was prepared by intravenous injection of ConA (15mg·kg-1)in the tail of mice in each group except for the control group one hour after the last treatment.The pathological changes of liver tissues of mice were evaluated by HE staining with, and the levels of alanine amino transferase (ALT),as-partate aminotransferase (AST),and total bilirubin (TBIL)in serum were analyzed by colorimetric meth-od;the level of interleukin 12 (IL-12 ),interferon-γ(IFN-γ),tumor necrosis factor-α(TNF-α),interleu-kin 4 (IL-4)and interleukin 10 (IL-10)in liver was measured by real-time quantitative polymerase chain reaction (RT-qPCR);the changes of Th1 (IFN-γ) and Th2 (IL-4)cells were observed by flow cytometric (FCM)analysis;the expression of Th1/Th2 transcrip-tion factor T-bet/GATA-3 in liver tissue was detected by Western blot.Results Compared with normal con-trol group,the serum ALT,AST and TBIL were signif-icantly increased in model group, the pathological damage of the liver tissue was severe,and the necrosis and apoptosis of hepatic cells were large, which showed that the model was successful .Compared with model group,both low and high dose of LWWL could significantly reduce ALT,AST,TBIL levels in serum induced by ConA;Th1 cells in the spleen decreased, while Th2 cells increased;the expressions of IL-12, IFN-γand TNF-αmRNA were significantly inhibited with IL-4 and IL-10 mRNA expression elevated in mouse liver tissue;the expression of GATA-3 protein was up-regulated,T-bet protein expression showing no significant changes.Conclusion LWWL could regu-late Th1/Th2 balance,thus inhibiting the acute immu-nity hepatic injury induced by ConA.

In the field of dental aesthetics,digital aesthetic design plays a crucial role in helping dentists to predict treatment outcomes vis-ually,as well as in enhancing the consistency of knowledge and understanding of aesthetic goals between dentists and patients.It serves as the foundation for achieving ideal aesthetic effects.However,there is no clear standard for this digital process currently in China and abroad.Many dentists lack of systematic understanding of how to carry out digital aesthetic design for treatment.To establish standardized processes for dental aesthetic design and to improve the homogeneity of treatment outcomes,Chinese Society of Digital Dental Industry(CSD-DI)convened domestic experts in related field to compile this consensus.This article elaborates on the key aspects of digital aesthetic data collection,integration steps,and the digital aesthetic design process.It also formulates a decision tree for dental aesthetics at macro level and outlines corresponding workflows for various clinical scenarios,serving as a reference for clinicians.
