Effect of vacuum sealing drainage combined with continuous fluid irrigation in deep second degree burn / 中国实用护理杂志

Objective To discuss the value of vacuum sealing drainage combined with continuous fluid irrigation in deep second degree burn.Methods 33 patients with deep second degree burns in burn department of the Third Affiliated Hospital of Qiqihar Medical College were selected as study object.The observation group used vacuum sealing drainage combined with continuous fluid irrigation,while the control group used the traditional method of treatment.The rate of wound healing,wound healing time and pain conditions were compared between the two groups of patients.Results After 3 days in the observation group,there was dissolved necrotic tissue which were drained into the negative pressure bottles,wound necrosis dropped off and dissolved when changing VSD dressings after seven days,a large number of newborn epithelial tissue appeared on the wound after 14 days of treatment.The healing rate after 7 days and 14 days,total healing time and wound pain showed statistically significant differences between two groups.Conclusions VSD combined with continuous fluid irrigation can effectively improve local microcirculation of burn wounds,increase local blood flow,keep the wound stay at a moist environment,accelerate the exudate drainage,which will help reduce the damage caused by local inflammation,promote epithelial cell regeneration from multiple perspectives,promote wound healing,and improve local pain symptoms and the quality of life of patients.

Experimental study on inhibitory effect of GFW on transplantable tumor cell metastasis in S180 tumor-bearing mices / 中国中药杂志

<p><b>OBJECTIVE</b>To detect the effect of GFW on tumor cell metastasis in S180 tumor-bearing mice.</p><p><b>METHOD</b>S180 tumor-bearing mice model were replicated and divided randomly into 4 groups: the model group, the GFW group, the cyclophosphamide group and the combination administration group. VEGF in serum on each group was detected by ELISA, and the expression of metastasis suppressor gene nm23H1 and cell adhesion molecule CD44 in Sarcoma were detected by SABC immunohistochemical assay.</p><p><b>RESULT</b>Compared with the model group, the GFW group showed a significant decrease in VEGF in serum (P < 0.01). From their statistically significant difference, GFW was proved to promote the expression of metastasis suppressor gene nm23H1 and inhibit the expression of cell adhesion molecule CD44 (P < 0.05).</p><p><b>CONCLUSION</b>GFW has an effect on inhibiting tumor metastasis to some extent.</p>
