ABSTRACT

OBJECTIVE:To study the repa ir,anti-inflammatory and analgesic effects of Compound crocodile oil burn ointment on superficial second-degree burned skin. METHODS :The heated weight was attached to the right depilated skin of guinea pigs for 4 s to induce the model of superficial second-degree burn. After modeling ,guinea pigs were randomly divided into model group , Jingwanhong ointment group (positive control ),formula Ⅰ,Ⅱ and Ⅲ groups of Compound crocodile oil burn ointment (volume fraction 1.5%,3%,4.5%,hereinafter),with 8 guinea pigs in each group. Except for model group ,other groups were smeared with 0.7 g/guinea pigs twice a day for 14 consecutive days. The wound healing was recorded every day ,the healing rate of wound was calculated. HE staining was used to observe the histopathological changes of the wound. The serum levels of EGF ,VEGF, SOD,MDA,TNF-α and IL-1 were detected by ELISA. Eighty Kunming mice were divided into 2 groups,and then sub-grouped into model group ,Jingwanhong ointment group (positive control ),formula Ⅰ and Ⅲ groups of Compound crocodile oil burn ointment,with 10 mice in each group. Then xylene auricle swelling method and acetic acid writhing method were used to investigate the anti-inflammatory and analgesic effects of Compound crocodile oil burn ointment. RESULTS :In the burn repair experiment,after intervention of Compound crocodile oil burn ointment ,the wound area of guinea pigs gradually decreased ,and on the 14th day ,the wound had healed greatly ,and the wound healing rate increased significantly (P<0.01);serum levels of EGF and SOD were increased significantly (P<0.01),while the levels of VEGF ,MDA,TNF-α and IL-1 were decreased significantly(P<0.05 or P<0.01). The thick new epidermal layer was found in wound tissue ,and the connective tissue and neovascularization in the dermis increased significantly. In the anti-inflammatory and analgesic experiment ,after intervention of Compound crocodile oil burn ointment ,the degree of ear swelling and the times of writhing decreased significantly (P<0.05 or P<0.01). CONCLUSIONS :Compound crocodile oil burn ointment shows good skin repair ,anti-inflammatory and analgesic efficacy;the mechanism may be associated with increasing the serum levels of EGF and SOD and reducing the levels of VEGF , MDA,TNF-α,IL-1.

ABSTRACT

Objective To explore the correlation between wedged hepatic vein pressure (WHVP) and directly measured portal vein pressure (PVP) and further analyze the correlation between hepatic venous pressure gradient (HVPG) and portal pressure gradient (PPG).Methods From December 2012 to April 2014,the related data including WHVP,free hepatic venous pressure (FHVP),inferior vena cava pressure (IVCP) and PVP of patients who received transjugular interahepatic portosystem stentshunt (TIPS) treatment were collected,and HVPG and PPG were calculated.The correlations between WHVP and PVP,between FHVP and IVCP,between HVPG and PPG were analyzed.Pearson's correlation analysis were performed for correlation analysis.Results Twenty two patients matched the criteria were enrolled during the December 2012 to April 2014.The mean pressures of PVP and WHVP were (28.07±4.43) mmHg (1 mmHg=0.133 kPa) and (26.22±5.91) mmHg,respectively.PVPand WHVP were positively correlated,the correlation coefficient of them was 0.431 (P=0.045) and slope was0.323.The mean pressures of FHVP and IVCP were (7.31±3.37) mmHg and (6.82±4.01) mmHg,respectively.FHVP and IVCP were positively correlated,the correlation coefficient of them was 0.845 (P<0.01) and slope was 0.711.The mean pressures of PPG and HVPG was (21.02±3.76) mmHg and (18.90±4.86) mmHg,respectively.There was no correlation between PPG and HVPG,the correlation coefficient of them was 0.014 (P=0.951).Conclusions There is a good correlation between PVP and WHVP,and so is the correlation between FHVP and IVCP.However,there is no good correlation between HVPG and PPG in this study because of the effects of many factors.
