Objective:To systematically search and evaluate risk prediction models for ventilator-associated pneumonia (VAP) of ICU in order to provide references for developing higher-quality VAP risk prediction models.Methods:Relevant literature was retrieved from databases including China Biology Medicine disc, WanFang data, China National Knowledge Infrastructure, Embase, PubMed, CINAHL, Web of Science, and Cochrane Library. The search timeframe was from the establishment of the databases to September 30, 2023, limited to English and Chinese languages. Two researchers independently screened the literature and extracted data, and the PROBAST tool was used to evaluate the risk of bias and applicability of the included studies.Results:A total of 15 studies on VAP risk prediction models were included. The area under the receiver operating characteristic curve for the 15 models ranged from 0.722 to 0.982. The most frequently involved predictors were age, duration of mechanical ventilation, ICU length of stay, and comorbid chronic obstructive pulmonary disease. The overall adaptability was good, but the risk of bias was high. The main sources of bias included insufficient sample size, inappropriate data sources, lack of model performance evaluation, and inadequate attention to missing data.Conclusions:The risk of bias in studies on VAP risk prediction models is high, indicating that the field is still developing. Future research should focus on the effectiveness of different risk assessment methods to construct models with low bias, excellent predictive performance, and suitability for clinical practice in China.

Objective:To investigate the clinical characteristics and prognosis in adult acute myeloid leukemia (AML) patients with FLT3-ITD and CEBPA double-mutated (CEBPAdm) co-mutation.Methods:Clinical data and prognostic factors were retrospectively analyzed in adult AML patients with FLT3-ITD and CEBPAdm co-mutation at The First Affiliated Hospital of Zhengzhou University from January 2016 to September 2018.Results:Among 599 non-acute promyelocytic leukemia (APL) patients, 268 received gene mutation detection, who were divided into 4 groups including 19 FLT3-ITD positive (FLT3-ITD +) and CEBPAdm positive (CEBPAdm +) cases (group A) , 84 FLT3-ITD + and CEBPAdm - cases (group B) , 95 FLT3-ITD - and CEBPAdm + cases (group C) , 70 double negative mutation cases (group D) . Gender, platelet count, FAB classification, induction treatment regimen and fusion gene mutation were comparable among four groups ( P>0.05) , while age onset, peripheral white blood cell (WBC) count, hemoglobin, percentage of blasts in peripheral blood, percentage of blasts in bone marrow, complete remission rate (CR 1 rate) after the first induction chemotherapy, the relapse rate, the median progression-free survival (PFS) time, and median overall survival (OS) time were significantly different between groups ( P<0.05) . When compared in pairs, gender, age onset, hemoglobin, platelet count, FAB classification in group A were not statistically different compared to group B, C and D ( P>0.05) , while patients in group A had higher WBC count, blasts in peripheral blood, minimal residual disease (MRD) in bone marrow. The CR 1 rates of group A, B, C, and D were 50.0%、32.4%、59.8%、39.0% respectively ( P=0.003) , and the relapse rates were 55.6%, 50.0%, 21.1%, 40.0% ( P<0.001) . As to survival, the median OS in each group was 6.25, 3.0, 15.5, 10.5 months respectively ( P<0.001) , and the median PFS was 5.0, 4.0, 10.0, 6.7 months ( P=0.032) . Conclusion:Adult AML patients with FLT3-ITD and CEBPAdm co-mutation have a higher leukemia load and low CR 1 rate, which translates into poor prognosis with high relapse rate and short survival time.

Objective: To investigate the clinical characteristics and prognosis of adult acute myeloid leukemia (AML) with TLS-ERG fusion gene positive. Methods: Adult two AML patients with TLS-ERG fusion gene positive in the First Affiliated Hospital of Zhengzhou University in January 2017 and March 2018, respectively were enrolled, and their clinical characteristics and prognosis were analyzed. Results: Both patients with TLS-ERG fusion gene positive were males. According to morphology classification, the first case was classified to AML-M₅, and the other one was AML-M₄. Both patients' immunophenotypic features showed CD56 expression, and CD25 was expressed in the first patient simultaneously. Both patients were treated with induction and consolidated intensive therapy based on Chinese guidelines for diagnosis and treatment of adult AML (not acute promyelocytic leukemia) and the guidelines for diagnosis and treatment of AML (relapse/refractory) in China. The first patient died 11 months after diagnosis, and the second patient remained in remission until the end of follow-up in February 2019 (12 months after diagnosis). Conclusion TLS-ERG fusion gene has low incidence rate, high recurrence rate, poor reinduction effect, poor prognosis and short survival time in adult AML.

Objective To investigate the expression of DDX46 protein in colorectal cancer and its correlation with expressions of C-erbB-2, Ki-67, p53 and nm23 proteins. Methods A total of 149 cases of colorectal cancer tissues and 45 adjacent mucosa tissues after operation in the Wuxi No.2 Hospital Affiliated to Nanjing Medical University from January 2010 to December 2012 were collected. The expressions of DDX46 protein and C-erbB-2, Ki-67, p53 and nm23 proteins in tissues of colorectal cancer were detected by using immunohistochemistry. The relations between the expression level of DDX46 protein and the clinicopathological features including the age, gender, tumor differentiation, tumor infiltration, lymph node metastasis, TNM stage were analyzed, and the relations between DDX46 protein expression and expressions of C-erbB-2, Ki-67, p53 and nm23 proteins were also analyzed. Results Of 149 colorectal cancer tissues, 50 (33.6％) showed low expressions of DDX46 protein and 99 (66.4％) showed high expressions. Of 45 adjacent mucosa tissues, 37 (82.2％) showed low expressions of DDX46 protein, and 8 (17.8％) showed high expressions. There were significant differences between the high expression rate of DDX46 protein in cancer tissues and adjacent mucosa tissues (χ2=33.09, P<0.01). There were statistical differences in the expression level of DDX46 protein and tumor differentiation, tumor infiltration, lymph node metastasis, TNM staging (all P<0.05). The ratio of high-expressed DDX46 protein was increased with the low differentiation, high invasion degree, lymph node metastasis and late TNM staging. DDX46 protein expression was correlated with expressions of Ki-67, p53 and nm23 proteins (all P< 0.05), and the expression of DDX46 protein had a positive correlation with expressions of Ki-67 and p53 proteins (r values were 0.161 and 0.347), and a negative correlation with expression of nm23 protein (r= -0.561). Conclusions The high expression of DDX46 protein in colorectal cancer tissues is related with malignant biological behavior of the tumors and the key oncogenes. DDX46 protein could be regarded as the potential marker for the diagnosis and molecular targeting therapy of colorectal cancer.

Objective: To evaluate the population immunity to measles and explore the factors associated with measles susceptibility in Yunnan residents aged ≥20 years. Methods: 2 689 residents aged ≥20 years were selected by multistage stratified systematic randomized sampling in 252 villages of 42 counties in Yunnan Province between June and September in 2015. Each subject was surveyed by the same questionnaire, including general information, measles contained vaccine history, measles history, and 5 ml blood sample of each subject was collected. Serum IgG antibodies against measles virus were measured by ELISA. Positive was defined as the antibody concentration ≥250 mU/ml, and negative as <250 mU/ml. Non-conditional logistic regression model was used analyze the factors associated with measles susceptibility in adults. Results: Among 2 689 subjects, 1 214 were males (45.15%), and the overall positive rate of measles IgG antibody was 89.77%. Compared with subjects from the region where economic development was low, subjects from the region where economic development was moderate were likely to be susceptible to measles virus (OR=1.81, 95%CI: 1.33-2.47). Four age groups had higher risk of being susceptible to measles virus (compared with ≥40 years: 20-24 years old, OR=2.04, 95%CI: 1.26-3.31; 25-29 years old, OR=3.72, 95%CI: 2.37-5.86; 30-34 years old, OR=1.94, 95%CI: 1.22-3.09; 35-39 years old, OR=1.81, 95%CI: 1.07-3.05). Conclusion Our results suggest that the serological susceptibility in adults (20-39 years), especially adults from the regions where the economic development was moderate, should be concerned. The additional vaccination strategy targeting young adults is important for reducing the risk of measles infection.
