ABSTRACT
Objective: To investigate the prevalence and risk factors of cooking-related child burn injury. Methods: A cross-sectional community-based study was conducted among a total of 5830 children with their respective caretakers in randomly selected 100 clusters. Data were collected through face-to-face interviews using a structured questionnaire. Logistic regression was used to identify the risk factors and adjusted odds ratios were used as measures of effect. Results: The prevalence of cooking-related child burn injury was 6.2% (95% CI: 5.5-6.8). This burden was linked with risk factors such as lower literacy of caretaker, family size, using traditional cook stove, long cooking time, and presence of extra indoor burning events as well as lack of separate kitchen, child supervision, and injury prevention awareness. Conclusion: Children experience a high burden of burn injury. Thus, stakeholders should work to reduce this burden by controlling the aforementioned risk factors.
ABSTRACT
The anti-inflammatory activity and compatibility ratio of flavonoids in Glycyrrhizae Radix et Rhizoma Praeparata Cum Melle(GR) and Angelicae Sinensis Radix(AS) were evaluated by the superoxide anion scavenging test. The matrix formula of gel was optimized by orthogonal test design and the model of deep partial-thickness scald in mice was induced. The gel was applied to the wound. The tissue water content, wound healing rate, serum TNF-α and IL-1, and EGF and VEGF in tissues were measured at diffe-rent periods. The results revealed that when the compatibility ratio of GR and AS was 1∶2, the maximal scavenging efficacy on supe-roxide anion was observed. The gel displayed the optimal properties when carbomer(1%), glycerol(5%), propylene glycol(10%) were added into the matrix. Gel external application can significantly improve the wound healing rate, relieve tissue edema, diminish tissue water content, alleviate inflammatory reaction, and increase the content of EGF and VEGF in tissues(P<0.05). The gel prepared in the present study is effective in promoting granulation, relieving pain, resisting inflammation, and alleviating edema, and is potent in healing scalds.

Objective To study the effect of low intensity laser irradiation on wound healing and the expression of transforming growth factor beta-1 (TGF-β1) and interleukin beta-1 (IL-1β) in wounded tissue.Methods Steam was used to scald 60 BALB/c mice.They were then randomly divided into a laser group and a control group with 30 in each group.The wounds in the laser group were irradiated with a low-intensity He-Ne laser,while the control group was given the same treatment except that the instrument was turned off.The wound healing rate was calculated,and the full wound thickness was measured and a reverse transcription polymerase chain reaction (RT-PCR) was used to detect the expression of TGF-β1 and IL-1β right after the scalding and 1,3,7 and 14 days later.Results Seven and 14 days later,the wound healing rates in the laser group were (51.48 ± 5.89) ％ and (73.96 ± 7.25) ％,respectively.Compared with the control group at the same time points,the difference was statistically significant.In the laser group the expression of TGF-β1 had increased significantly at days 1 and 3,then increased to a maximum at day 7.It was significantly greater than in the control group at all three of those time points.At day 14 the expression of TGF-β1 in the laser group was significantly lower than in the control group.The expression of IL-1 β in the laser group had decreased significantly at days 1 and 3,and gradually reduced to a minimum at day 7.It was significantly lower than in the control group at all three of those time points.Conclusion Low intensity He-Ne laser irradiation can accelerate wound healing after scalding,at least in mice.Its effect may be related to its regulation of the expression of IL-1 β and TGF-β1.
ABSTRACT
Objective To study the effects of compound rhizoma bletillae paint (CRBP) on scalded rats. Methods Rats were randomly divided into test groups (CRBP low, high dose group), CRBP-CA (CRBP without chlorhexidine acetate) group, positive control group (Jingwanhong) and negative control group (no treatment) respectively, with 10 rats in each group. The drugs were administered topically on the surface of scalded places respectively after second-degree and third-degree burn scald models in rats. The rats were bred separately. The scabbing time, decrustation time and wound healing time were recorded. Results The scabbed and the decrustation time were shorter in the test group than that in the negative control group with significant differences (P
