Objective To investigate the relationship between the expression of mast cell expressed membrane protein 1 (MCEMP1) in gastric cancer and its relationship with prognosis and tumor immune infiltration. Methods Transcriptome expression profile data and clinical data information of gastric cancer and normal samples were downloaded from TCGA database, and differentially expressed genes in gastric cancer tumor microenvironment were extracted using R 4.0.5 software. Protein-protein interaction network of differentially expressed genes was constructed by using STRING online website, protein-protein interaction network and univariate Cox proportional hazards regression analysis were used for cross-tabulation analysis to obtain key genes. Kruskal-Wallis rank sum test was used to investigate the correlation between key genes and clinicopathological features. The possible signaling pathways involved in key genes were predicted by gene set enrichment analysis. We further analyzed the relationship between expression of key gene and the level of immune infiltration and immune molecules in gastric cancer by TISIDB online database and CIBERSORT algorithm. Results A total of 760 differentially expressed genes in gastric cancer were found and a key gene of MCEMP1 was derived from cross-tabulation analysis based on the results of protein-protein interaction network and univariate Cox proportional hazards regression analysis. Expression of MCEMP1 was significantly upregulated in gastric cancer tissues (P<0.001), and survival analysis showed that the overall survival rate of the group with high expression level of MCEMP1 was lower than that of low expression [HR=1.176, 95%CI (1.066, 1.297）, P=0.046]. Expression of MCEMP1 also correlated with age, T-stage, and clinical stage of gastric cancer (P<0.05) , and expression of MCEMP1 was significantly associated with a variety kinds of immune cells and expression of immune molecules (P<0.05). Conclusion MCEMP1 is a potential prognostic marker for gastric cancer and is associated with immune infiltration in gastric cancer.
ObjectiveTo evaluate the health economics indexes of day surgery mode and traditional specialist hospitalization mode, and to provide reference for the selection of different hospitalization mode of inguinal-type cryptorchidism in children.MethodsThe patients with unilateral cryptorchidism under 5 years old between January 2017 and January 2018 in Chongqing Children’s Hospital were selected in this study. According to different inpatient surgery modes, the included children were divided into day surgery group (day group) and special in-hospital surgery group (specialty group). The general data of patients, treatment indicators, incidence of complications, postoperative testicular atrophy rate, recurrence, nosocomial infection, hospitalization time, hospitalization cost, satisfaction of patients, and other health effect indicators between the two operation modes were compared. The treatment effect indexes and cost-effect ratio of the two modes were statistically analyzed.ResultsA total of 198 children were included, including 83 in the day group and 115 in the specialty group. The patients in both groups underwent orchiopexy by small inguinal dermatoglyph and scrotal incision. There was no statistically significant difference in the affected side, source area, postoperative complications, or nosocomial infection between the two groups (P>0.05). The patients in the specialty group were older than those in the day group [(27.60±11.04) vs. (20.88±9.48) months old; t=4.586, P<0.001]; the bed occupancy time [(118.60±10.80) vs. (23.95±5.90) h; t=72.353, P<0.001] and operation time [(0.45±0.15) vs. (0.38±0.12) h; t=2.946, P=0.004] in the specialty group were longer than those in the day group. The difference was statistically significant in hospitalization expenses between the two groups (χ2=155.374, P<0.001); 92.8% of the children in the day group spent less than 5 000 yuan, while 95.7% of the children in the specialty group spent more than 5 000 yuan. The American Society of Anesthesiologists scores in the specialty group were higher than those in the day group (χ2=44.870, P<0.001). The treatment effect indexes in the day group and the specialty group were 0.99 and 1.01, respectively, and the cost-effect ratios were 3 850 and 6 657, respectively. The economic benefit of the day group was better.ConclusionsThe cost-effectiveness of day surgery is better than that of specialized inpatient surgery. Therefore, this model can be recommended for children who meet the indications of day surgery.
