【Objective】 To demonstrate the real incidence and clinical features of acute transfusion reactions (ATRs) and analyze its association with transfusion effectiveness. 【Methods】 The blood transfusion process of patients in the Hematology Department in our hospital from March 16, 2018 to March 16, 2019 was observed and followed up. The vital signs and clinical features were recorded, the clinical data and relevant laboratory examination results were collected, and the correlation between ATRs, clinical features and transfusion effectiveness was statistically analyzed. 【Results】 A total of 2500 transfusions were observed in the Hematology Department, out of which 138 patients developed 242 ATRs. The overall incidence of ATRs was 9.68% (95% CI, 8.52%~10.94%) and the incidence of ATRs during platelets transfusion was the highest. The clinical features of most ATRs were mild and no fatal consequences occurred. No significant difference was found in the association between transfusion effectiveness with ATRs in platelets and red blood cells transfusion (P>0.05). 【Conclusion】 None of the ATRs observed in this study resulted in serious consequences or had effect on the transfusion effectiveness. The characteristics presented in these reactions may provide certain references for clinical practice.

Objective:To study the epidemic and etiologic characteristics of influenza virus(Flu)and respiratory syncytial virus (RSV) infections in outpatient influenza-like illness(ILI)cases of children under 10 years of age in Gansu province in 2018 And to provide evidences for diagnosis, treatment, control and prevention of Flu and RSV infections in Gansu province.Methods:A total of 8 559 pharyngeal swab samples of ILI outpatients cases were tested with real-time fluorescent PCR to detect Flu, 3 436 of which were detected by RT-PCR for RSV.Results:Of the 8559 specimens, 934 (10.91%) samples were positive for Flu. Among them, 431 were positive for H1N1, 70 were positive for H3N2, 428 were positive for Flu B, 5 were mixed; 320 of the 3436 (9.31%, ) samples were positive for RSV. There were significant differences in the positive rates of Flu and RSV among 14 cities and prefectures ( χ2=56.99, χ2=263.34, Р< 0.01). Influenza reached its peak in January 2018 with a positive rate of 50.70%. Flu B/Yamagata strain (53.53%) and A H1N1 (39.93%) were prevalent simultaneously. The peak of RSV epidemic was from February to April, the positive rate was 13.98%. The RSV positive rate of children under 5 years of age was 10.11%, higher than that of children over 5 years of age was 6.94%. There was statistical significance ( χ2=7.67, Р<0.01). Conclusions:RSV and influenza viruses are the main pathogens in ILI cases of children under 10 years of age. There are epidemic peaks in winter and spring every year. It is suggested that the monitoring of RSV and the development and application of vaccine should be strengthened.

PURPOSE: Breast cancer is the most frequently diagnosed malignancy in women worldwide. MicroRNAs (miRNAs) are thought to serve as potential biomarkers in various cancers, including breast cancer. METHODS: We evaluated the miRNA expression profiles in 1,083 breast cancer samples and 104 normal breast tissues from The Cancer Genome Atlas database. We used the edgeR package of R software to analyze the differentially expressed miRNAs in normal and cancer tissues, and screened survival-related miRNAs by Kaplan-Meier analysis. A receiver operating characteristic curve was generated to evaluate the accuracy of these miRNAs as molecular markers for breast cancer diagnosis. Furthermore, the functional role of these miRNAs was verified using cell experiments. Targets of candidate miRNAs were predicted using 9 online databases, and Gene Ontology (GO) functional annotation and pathway analyses were conducted using Database for Annotation, Visualization and Integrated Discovery online tool. RESULTS: A total of 68 miRNAs showed significantly different expression patterns between the groups (p < 0.001), and 13 of these miRNAs were significantly associated with poor survival (p < 0.05). Three miRNAs with high specificity and sensitivity, namely, miR-148b-3p, miR-190b, and miR-429, were selected. In vitro experiments showed that the overexpression of these 3 miRNAs significantly promoted the proliferation and migration of MDA-MB-468 and T47D cells and reduced the apoptosis of T47D cells. GO and pathway enrichment analyses revealed that the targets of these dysregulated miRNAs were involved in many critical cancer-related biological processes and pathways. CONCLUSION: The miR-148b-3p, miR-190b, and miR-429 may serve as potential diagnostic and prognostic markers for breast cancer. This study demonstrated the roles of these 3 miRNAs in the initiation and progression of breast cancer.
