BACKGROUND:Postoperative results with Meek skin grafting in some patients with extremely severe burns have not been satisfactory,with problems of delayed healing or skin graft failure. There have been fewer studies on the treatment of patients with failed Meek skin grafting due to insufficient skin source. This study aimed to explore a treatment method for such patients. OBJECTIVE:To observe the curative effect of stamp-shaped skin allograft in the treatment of severe burns after Meek skin graft failure. METHODS:Twenty-three patients with extremely severe burns who were admitted at Department of Burns and Skin Surgery,the First Affiliated Hospital of the Air Force Medical University from August 2013 to August 2023 with poor healing after Meek skin grafting were enrolled and divided into allogeneic skin treatment group and dressing change group according to different treatment methods. There were 10 cases in the allograft group and 13 cases in the dressing change group. Preoperative hemoglobin,platelet count,albumin count,white blood cell count,neutrophil count,procalcitonin count,and positive rate of microbial culture before secondary Meek skin grafting were compared between two groups. Survival rate of skin grafts before and after the second operation were compared. The number of operations,incidence of sepsis,and wound scars at 3 months and 6 months after operation were retrospectively analyzed. RESULTS AND CONCLUSION:The preoperative hemoglobin,platelet count and albumin count in the allogeneic skin treatment group were significantly higher than those in the dressing change group (Z=-3.172,P=0.002;Z=-3.010,P=0.003;Z=-2.761,P=0.006). There was no significant difference in the preoperative white blood cell count and neutrophil count between the two groups before secondary Meek skin grafting (Z=1.148,P=0.251;Z=0.373,P=0.709),but the serum procalcitonin count in the allogeneic skin treatment group prior to the second operation was significantly lower than that in the dressing change group (Z=2.955,P=0.002). Burn patients in the dressing change group exhibited a higher microbial culture rate than those in the allogeneic skin treatment group (x2=6.303,P=0.029). The survival rate of skin grafts before the second operation in the allogeneic skin treatment group[(74.8±13.3)％]was significantly higher than that in the dressing change group[(58.4±14.2)％;t=2.85,P=0.01). The survival rate of skin grafts after the second stage operation in the allogeneic skin treatment group[(84.0±11.5)％]was significantly higher than that in the dressing change group[(67.6±20.7)％;t=2.24,P=0.03). The frequency of postoperative surgery in the allogeneic skin treatment group was less than that in the dressing change group (Z=2.27,P=0.02). The incidence of sepsis in the dressing change group was significantly higher than that in the allogeneic skin treatment group (x2=5.490,P=0.03). There was no significant difference in the Vancouver Scar Scale scores of the scars between the two groups at 3 and 6 months after operation (t=0.96,1.138,P>0.05). To conclude,stamp-shaped skin allograft has good curative effect in the treatment of wounds with poor healing of skin after Meek micro-transplantation. The utilization rate of skin in the later stage is significantly increased,which reduces the probability of wound infection and solves the problem of insufficient skin source.

Objective:To explore the correlation between serum soluble triggering receptor expressed on myeloid cells 2 (sTREM2) and cognitive impairment in patients with cerebral small vessel disease (CSVD), and the role of deep medullary vein (DMV) score in this process.Methods:A total of 140 patients with CSVD admitted to the Department of Neurology, the First Affiliated Hospital of Henan Medical University from December 2022 to August 2024 were selected as the research objects. The basic data statistics, head magnetic resonance imaging examination, cognitive function assessment, serum sTREM2 detection and DMV score were performed. All data were analyzed by SPSS 29.0 software and GraphPad Prism 10.0 software packages. Logistic regression model was used to explore the influencing factors of cognitive impairment. Structural equation model was used to analyze the mediating effect of DMV score on the association between serum sTREM2 and cognitive impairment. Receiver operating characteristic (ROC) curve was used to evaluate the predictive value of serum sTREM2 level and DMV score for cognitive impairment in CSVD patients.Results:Serum sTREM2 level ( B=0.017, OR=1.017, 95% CI=1.003-1.031), DMV score ( B=0.375, OR=1.455, 95% CI=1.175-1.802) and years of education ( B=-0.248, OR=0.780, 95% CI=0.635-0.958) were risk factors for cognitive impairment (all P<0.05). sTREM2 not only directly affected cognitive function, but also indirectly affected cognitive function through DMV score. The direct effect (effect size=-0.022) and mediating effect (effect size=-0.007) accounted for 75.9% and 24.1% of the total effect (effect size=-0.029), respectively. The areas under the ROC curve of serum sTREM2 level, DMV score, and their combination for predicting cognitive impairment in CSVD patients were 0.880, 0.891, and 0.910, respectively (all P<0.001). Conclusion:Serum sTREM2 not only directly affects the cognitive function of patients with cerebral small vessel disease, but also indirectly affects cognitive function through DMV score. The combination of serum sTREM2 levels and DMV score has high predictive value for the risk of CSVD-related cognitive impairment.

Objective:Based on the autoregressive integrated moving average (ARIMA) model, back propagation neutral network (BPNN), and ARIMA-BPNN model, select the optimal model suitable for predicting the incidence trend of hepatitis C in Taiyuan City according to the characteristics of the data.Methods:The data of reported cases of hepatitis C in Taiyuan from 2008 to 2021 were selected, and the seasonal trend decomposition chart was used to analyze the seasonal characteristics of the monthly incidence rate of hepatitis C in Taiyuan during the period, and the ARIMA model, BPNN model, and ARIMA-BPNN model were established to predict. The performance of the model was measured using four indicators: mean absolute error ( MAE), mean squared error ( MSE), root mean square error ( RMSE), and mean absolute percentage error ( MAPE). Results:A total of 20 025 cases of hepatitis C were reported, and the overall incidence trend was stable. The BPNN model performed well on MSE, MAE, and RMSE indicators, the ARIMA-BPNN model performed well on MAPE indicators, and the ARIMA model performed relatively averagely. Conclusions:The ARIMA-BPNN model is a better model for predicting the trend of hepatitis C in Taiyuan City, with a higher predictive performance than a single model. It has significant prospects in predicting the trend of infectious diseases.
