【Objective】 To study the safety, effectiveness and nursing of blood/fluid warmer during the process of plateletpheresis in winter. 【Methods】 The blood re-transfusion speed during plateletpheresis in winter and the time of blood passing through the blood return pipeline was counted. The vitro blood was heated with a blood/fluid warmer under different temperature settings, and the rising speed of blood temperature was recorded. The blood samples were tested for blood routine examination, free Hb and erythrocyte morphology at 0, 15 and 30 minutes. In the process of plateletpheresis in winter, the blood donors′ ear temperature and the skin temperature near the reinfusion needle in the observation group and the controls were measured, and the blood donors were observed for shivering, arm chills, pain or other discomfort. After the blood donation, the thermal comfort was evaluated. 【Results】 There was no difference in the results of routine blood test and plasma free Hb test of vitro blood after warming at 41℃, 42℃ and 43℃ for 0, 15 and 30 minutes (P>0.05), and no change in erythrocyte morphology was found. The skin temperature near the reinfusion needle (before vs. after the start of phlebotomy) was statistically different by applying blood/fluid warmer or not(P<0.05), and no difference in the temperature between the start and end of phlebotomy was observed in the observation group(P>0.05). The vitro blood heating experiment showed that when the room temperature was within 22~24℃, the blood retransfusion speed was (100-120) mL/min; after the application of blood/fluid warmer, the temperature of reinfusion blood could be raised from 27℃ to 33~37℃. The proportion of feeling comfortable and very comfortable and the score of thermal comfort in the blood donors who used the warmer were higher than those in the controls (P<0.05). When the temperature of the warmer was set above 38℃, the average score of thermal comfort of blood donors was above 8. 【Conclusion】 It is safe to apply the blood/fluid warmer during the plateletsapheresis in winter, which can significantly improve the comfort of blood donors and reflect the humanized service of blood stations, and is worth popularizing.

Objective:To investigate the differential expression of four-jointed box kinase 1 (FJX1) gene in colorectal cancer and its relationship with prognosis and the related mechanisms.Methods:On July 16, 2021, the transcriptome data and clinical data of colorectal cancer were downloaded from The Cancer Genome Atlas (TCGA) database to analyze the expressions of FJX1 mRNA in colorectal cancer tissues and paracancerous tissues, and the relationship between FJX1 mRNA and clinicopathological characteristics and prognosis of patients. Receiver operating characteristic (ROC) curve was drawn to evaluate the value of FJX1 mRNA in predicting the survival of patients with colorectal cancer. Cox proportional hazards model was used to evaluate whether FJX1 mRNA was an independent influencing factor for prognosis of colorectal cancer. The overall survival (OS) time and survival status of colorectal cancer patients were downloaded from the Gene Expression Omnibus (GEO) database, and the relationship between FJX1 mRNA and prognosis of patients was analyzed. The methylation data of colorectal cancer was downloaded from the University of California, Santa Cruz (UCSC xena) database to determine the degree of methylation at each site of FJX1 mRNA and the correlation between the expression of FJX1 mRNA and the degree of methylation at each site. Signaling pathways associated with FJX1 mRNA in colorectal cancer were analyzed by using the Gene Set Enrichment Analysis (GSEA) (4.1.0). The correlation between FJX1 mRNA and tumor-infiltrating immune cells was investigated by using the Tumor Immunity Evaluation Resource (TIMER) database. Spearman analysis and small molecule/drug sensitivity analysis were used to explore the correlation between FJX1 mRNA expression and drug sensitivity.Results:In the transcriptome data of 612 colorectal cancer cases in TCGA database, the expression of FJX1 mRNA in colorectal cancer tissues was higher than that in the paracancerous tissues ( P < 0.001). In 549 colorectal cancer patients with complete data, FJX1 mRNA expression was correlated with M stage ( P = 0.007), pathological stage (stage Ⅳ vs. stage Ⅰ, P = 0.016; stage Ⅳ vs. stage Ⅱ, P = 0.03; stage Ⅳ vs. stage Ⅲ, P = 0.012), but it was not correlated with age, gender, T stage and N stage (all P > 0.05). In TCGA database and GEO database, the patients were divided into high expression group and low expression group according to the median expression of FJX1 mRNA. The OS in FJX1 mRNA high expression group was worse than that in low expression group (all P<0.05). The ROC curve of FJX1 mRNA expression on the 1-, 3-, and 5-year OS rates of colorectal cancer patients was drawn by using the data in TCGA database, and the areas under the curve (AUC) were 0.595, 0.625 and 0.764, respectively. Multivariate Cox regression analysis showed that age ( HR = 1.050, 95% CI 1.028-1.073, P < 0.001), T stage ( HR = 1.787, 95% CI 1.090-2.927, P = 0.021) and high FJX1 mRNA expression ( HR = 1.160, 95% CI 1.049-1.282, P = 0.004) were independent influencing factors for poor OS in colorectal cancer. The gene set enrichment analysis found that FJX1 mRNA was related to colorectal cancer, TGF-β signaling pathway, VEGF signaling pathway, Wnt signaling pathway, etc. The expression of FJX1 mRNA in colon cancer was negatively correlated with the degree of methylation of FJX1 mRNA ( r = -0.16, P < 0.001), and the expression of FJX1 mRNA in rectal cancer was positively correlated with the degree of methylation of FJX1 mRNA ( r = 0.33, P < 0.001). The expression of FJX1 mRNA was related to the infiltration of resting memory CD4 + T cells, M0 macrophages and resting dendritic cells. FJX1 mRNA was significantly associated with the resistance of various chemotherapeutic drugs and tumor-targeted drugs such as methotrexate, 5-fluorouracil, gefitinib, etc. Conclusions:FJX1 mRNA may be a potential biomarker of colorectal cancer and is associated with the infiltration of immune cells.

Objective:To observe the effect of autologous platelet-rich plasma (PRP) combined with Meek microskin grafts in repairing the wounds of limbs in severely burned patients, and to explore the mechanism.Methods:The prospective controlled research method was used. From September 2016 to January 2020, 16 patients aged 18-69 years, with extensive deep burns, including 9 males and 7 females, who met the selection criteria were admitted to the Department of Burns and Plastic Surgery of the 909th Hospital of the Joint Logistic Support Force of PLA. The bilateral limbs with similar injury in 8 patients were divided into Meek skin grafting+PRP group and Meek skin grafting alone group according to the random number table; in the other 8 patients, the limbs with severer injury were included in Meek skin grafting+PRP group, and the limbs on the other side were included in Meek skin grafting alone group. The wounds of affected limbs in the two groups were treated correspondingly. On post surgery day (PSD) 10, the survival and fusion of Meek microskin grafts were observed and the survival rate and fusion rate were calculated; the histological morphology and the angiogenesis of the basal tissue of Meek microskin graft were observed by hematoxylin-eosin staining and immunohistochemical staining, respectively, with the microvessels being counted. Data were statistically analyzed with paired sample t test. Results:On PSD 10, the wounds of affected limbs in Meek skin grafting+PRP group were dry, and most of the transplanted skin grafts were closely adhered to the basal tissue; while a small amount of exudate could be found in the wounds of affected limbs in Meek skin grafting alone group, and a small part of the transplanted microskin grafts fell off or poorly attached to the basal tissue. On PSD 10, the survival rate and the fusion rate of Meek microskin grafts in the wounds of affected limbs in Meek skin grafting+PRP group were (94±3)% and (86±4)%, which were significantly higher than (89±4)% and (79±4)% of Meek skin grafting alone group, respectively ( t=3.633, 4.229, P<0.01). On PSD 10, the basal epidermis was closely connected with dermis of Meek microskin grafts in the wounds of affected limbs in Meek skin grafting+PRP group, with more inflammatory cell infiltration and active microvascular hyperplasia, while the basal epidermis was less closely connected with dermis of Meek microskin grafts in the wounds of affected limbs in Meek skin grafting alone group, with obvious degeneration of collagen fibers under the dermis, less inflammatory cell infiltration, and slightly poor microvascular hyperplasia. On PSD 10, the distribution of microvessels in basal tissue of Meek microskin grafts in the wounds of affected limbs in Meek skin grafting+PRP group were densely clustered, while the distribution of microvessels in Meek skin grafting alone group were scattered, sparse, and dotted. On PSD 10, the number of microvessels in basal tissue of Meek microskin grafts in the wounds of affected limbs in Meek skin grafting+PRP group was 36±6 in each 400-fold visual field, which was significantly more than 29±7 of Meek skin grafting alone group ( t=2.671, P<0.05). Conclusions:Autologous PRP can effectively promote the survival rate and fusion rate of Meek microskin grafts in the wounds of limbs after escharectomy in severely burned patients by promoting angiogenesis at the base of Meek microskin grafts.

Objective To understand the current status of healthcare-associated infections (HAI) among inpatients in medical institutions of Wuhan, and to provide a scientific basis for improving the management of healthcare-associated infections. Methods A combined method of bedside investigation and case review of the patients’ medical records were used to investigate all hospitalized patients in 31 hospitals. Results A total of 42 429 inpatients were investigated, of whom 938 had HAI (2.21%), and 7 561 had community-associated infection (CAI, 17.82%). The top three departments with the highest prevalence rate of HAI were ICU (17.95%), hematology (8.49%), and neurosurgery (6.57%), while the top three departments with the highest prevalence rate of CAI were burns (75.00%), pediatric non-neonatal group (70.26%) and respiratory department (67.53%). Both healthcare-associated infections and community infections were mainly in the lower respiratory tract, which accounted for 47.33% and 53.00%, respectively. The main pathogens of both HAI and CAI were Gram-negative bacteria, which accounted for 65.03% and 57.73%, respectively. The use rate of antimicrobial drugs was 31.74%, and the detection rate of pathogenic bacteria before antimicrobial treatment was 55.77%. The three departments with the highest rates of the use of antibacterial drugs were the pediatric non-neonatal group (78.20%), the department of burns (75.00%) and the department of urology (73.24%). Conclusion ICU, hematology department, and neurosurgery department were high-risk departments for healthcare-associated infections. Pediatrics, burns, and urology departments were the departments with high use of antibacterial drugs. The pathogenic bacterial detection rate has declined, which needs to be strengthened.
