Conclusions Compared with HE staining, immunohistochemical staining, and Ziehl-Neelsen and immunohistochemical double staining, the immunofluorescence double staining is easy to operate, giving clear and intuitive images. It allows accurate imaging co-localization of MTB and foamy macrophages in paraffin-embedded tissue of clinical tuberculous wound.Objective To investigate the effects and mechanism of sodium hydrosulfide on rat epidermal cells intervened with serum from burned rat (hereinafter referred to as burn serum). Methods The experimental research method was used. Ten male Sprague-Dawley (SD) rats aged eight months were taken to prepare normal rat serum (hereinafter referred to as normal serum), 30 male SD rats aged eight months were taken to prepare burn serum after full-thickness burn, and epidermal cells (the third passage)isolated from 10 SD rats born one day were used for the experiments. The cells were divided into normal serum group treated with normal serum and burn serum group treated with burn serum. Cell counting kit 8 method was used to detect cell survival rate after 1, 2, 4, 6, and 8 h of culture, respectively, to screen the subsequent intervention time of burn serum. The cells were divided into burn serum control group treated only with burn serum and 50, 100, 150, 200, 250 μmol/L sodium hydrosulfide groups treated with burn serum+chanism which is related to the alleviation of epidermal cell mitochondrial damage and mediated by ATP-sensitive potassium channel.Recently, more and more clinical and basic studies have shown that early intervention of scars after wound healing can shorten the immature period of scars, improve the final outcome of scars, effectively prevent and control the occurrence and development of pathological scars. However, there are many methods for early management of scars with varying quality, and there is a lack of expert consensus on early
