Objective: To understand the infection status of Enterovirus (EV) in cases of acute respiratory infections (ARIs) in Luohe City, Henan Province from 2017 to 2021, and analyze the prevalence and type composition of EV in ARIs. Methods: From October 2017 to May 2021, pharyngeal swab samples were collected from 1 828 patients with ARIs in Luohe Central Hospital and the clinical epidemiological data of these cases were also collected. EV-positive samples were identified by Quantitative Real-time Polymerase Chain Reaction (qPCR). The 5'-untranslated region (5'UTR) was amplified by Reverse Transcription-Polymerase Chain Reaction (RT-PCR). The results of 5'UTR region were initially typed by Enterovirus Genotyping Tool Version 1.0. Based on the typing results, the full-length of VP1 region was amplified by RT-PCR. The EV typing was identified again by VP1 region. Results: Among 1 828 cases of ARIs, 56.7% (1 036) were males. The median (Q1, Q3) age was about 3 (1, 5) years. Patients under 5 years old accounted for 71.6% (1 309 cases). Among all cases, a total of 71 EV-positive samples were identified by qPCR, with a detection rate of 3.88% (71/1 828). The EV detection rates for men and women were 3.28% (34/1 036) and 4.67% (37/792), without statistically significant differences (χ2=2.32, P=0.14). The EV detection rates for 2 to <6 years, 6 months to <2 years, 6 to <10 years, and <6 months were 6.29% (48/763), 3.00% (18/600), 2.52% (4/159), and 1.67% (1/60) (χ2=27.91, P<0.001). The EV detection rate was 0.92% (3/326) in autumn and winter of 2017. The EV detection rates were 1.18% (6/508), 2.47% (12/485) and 8.31% (34/409) in each year from 2018 to 2020, with an increasing trend year by year(χ2trend=29.76, P<0.001). The main prevalent seasons were summer and autumn. The detection rate in spring of 2021 was 4.00% (4/100). A total of 12 types were identified and classified as CVA2, CVA4, CVA5, CVA6, CVA10, CVB3, CVB5, E5, E11, E30, PV-1, and EV-D68. The types of CVA2, CVA10, CVA6, and CVB3 were the dominant phenotypes. In 59 sample of EV typing, the main clinical manifestation was upper respiratory tract infection (36/59, 61.01%). The dominant types detected in upper respiratory tract infections were CVA10 (10/36, 27.78%), CVA6 (9/36, 25.00%) and CVB3 (8/36, 22.22%). The dominant type detected in lower respiratory tract infections was CVA2 (7/19, 36.84%). Conclusion: In Luohe City, Henan Province from 2017 to 2021, EV infection in ARIs cases has clear seasonal and age-specific patterns, and the dominant types of upper and lower respiratory tract infections are different.

Screening of miRNAs associated with lymph node metastasis in Her-2-positive breast cancer and their relationship with prognosis / 浙江大学学报（英文版）（B辑：生物医学和生物技术）

The aim of this study was to identify some biomarkers for predicting lymph node metastasis and prognosis of human epidermal growth factor receptor 2 (Her-2)-positive breast cancer (BC). We analyzed correlations between microRNAs (miRNAs) and the prognosis of patients with BC based on data collected from The Cancer Genome Atlas (TCGA) database. The expression levels of miR-455, miR-143, and miR-99a were measured in clinical samples of Her-2-positive BC patients with different degrees of lymph node metastasis. We investigated the impacts of overexpressed miR-455 on the proliferation and invasiveness of MDA-MB-453 cells and measured its effects on the expression of long non-coding RNA (lncRNA) metastasis-associated lung adenocarcinoma transcript 1 (MALAT1) by quantitative real-time polymerase chain reaction (qRT-PCR). The expression of miR-455 was significantly and positively correlated to the prognosis and overall survival (OS) of the BC (P=0.028), according to TCGA information. The expression level of miR-455 was positively correlated with OS and relapse-free survival (RFS) of patients with Her-2-positive BC, and was negatively correlated with the number of metastatic lymph nodes (P<0.05). Transwell assay suggested that MDA-MB-453 cells became much less invasive (P<0.01) after being transfected with miR-455 mimics. During the qRT-PCR, the expression level of MALAT1 declined significantly after transfection (P<0.01). Overexpressed miR-455 significantly inhibited the proliferation and migration of MDA-MB-453 cells and the expression of MALAT1. We conclude that miR-455 may be a useful potential biomarker for forecasting lymph node metastasis and the prognosis of Her-2-positive BC patients. miR-455 may play an important role in lymph node metastasis of BC by interacting with MALAT1.

Value of body fat mass measured by bioelectrical impedance analysis in predicting abnormal blood pressure and abnormal glucose metabolism in children / 中国当代儿科杂志

OBJECTIVE@#To study the value of body fat mass measured by bioelectrical impedance analysis (BIA) in predicting abnormal blood pressure and abnormal glucose metabolism in children.@*METHODS@#Stratified cluster sampling was used to select the students aged 6-16 years, and a questionnaire survey and physical examination were performed. The BIA apparatus was used to measure body fat mass. Body mass index (BMI), body fat mass index (FMI), and fat mass percentage (FMP) were calculated. Fasting blood glucose level were measured.@*RESULTS@#A total of 14 293 children were enrolled, among whom boys accounted for 49.89%. In boys and girls, the percentile values (P, P, P, P, P, P, P, P) of FMI and FMP fitted by the LMS method were taken as the cut-off values. Based on the receiver operating characteristic curve analysis, the P values with a better value in predicting abnormal blood pressure and blood glucose metabolism were selected as the cut-off values for excessive body fat. When FMI or FMP was controlled below P, the incidence of abnormal blood pressure or abnormal glucose metabolism may be decreased in 8.25%-43.24% of the children.@*CONCLUSIONS@#The evaluation of obesity based on FMI and FMP has a certain value in screening for hypertension and hyperglycemia in children, which can be further verified in the future prevention and treatment of obesity and related chronic diseases in children.

A comparative study on diagnostic cut points of dyslipidemia in children and adolescents in China / 中华流行病学杂志

To compare the power of dyslipidemia diagnosis by different sets of cut points in the prediction of cardiovascular metabolic risk factors and identify the appropriate cut points for the diagnosis of dyslipidemia in children and adolescents in China. Data were obtained from the baseline survey of 'School-based Cardiovascular and Bone Health Promotion Program' in Beijing in 2017. Dyslipidemia was diagnosed by using two set of cut points. Receiver operating characteristic curve analysis was conducted to assess the power of dyslipidemia diagnosis by the two set of cut points to predict the prevalence of hypertension, obesity, high fat mass percentage and impaired fasting glucose. A total of 14 390 children and adolescents were in included in the study. The prevalence rates of high TC, high LDL-C, low HDL-C, and high TG in the participants were 2.7, 2.7, 14.4, and 3.7 according to 'Chinese Reference Standard', and 5.0, 3.7, 13.3, and 3.5 according to 'China Expert Consensus'. Low HDL-C and high TG defined by the 'Chinese Reference Standard' had better performance for the prediction of high fat mass percentage and obesity in boys, but worse performance in girls (<0.001). Using 'China Reference Standard' can increase the true positive rate in the prediction of obesity or high fat mass percentage in boys, and reduce the false positive rate in girls. The cut points for the diagnosis of dyslipidemia in Chinese children and adolescents need to be further validated by using national representative sample and in longitudinal study.

Spectrum of thalassemia mutations in fetuses of Han and Li ethinicities in Hainan province, China

To analyze the frequency and spectrum of thalassemia mutations in amniotic fluid samples collected from Han and Li people in Hainan province of China. Methods: We carried out a retrospective analysis on prenatal diagnosis of amniotic fluid samples collected from pregnant women who may have next generation with high risks of medium or severe thalassemia between 2005 and 2016. Diverse fetal thalassemia genotypes and mutated alleles in Han and Li people were analyzed and cmpared. Results: We examined 536 amniotic fluid samples from Han people and 588 from Li people, among which 406 Han and 500 Li samples were found to carry at least one thalassemia gene mutation, with a detection rate of 75.75% and 85.03%, respectively. Among all - and β-thalassemia mutant alleles detected, the most frequently found mutations in Han and Li samples were SEA-type of -thalassemia and 41/42 (-CTTT) of β-thalassemia, respectively. A total of 75 severe thalassemia cases were identified in Han samples and 53 in Li samples. In most of these severe cases, parents chose to terminate pregnancy after being informed of thalassemia-related risks. Conclusions: The thalassemia mutations shows ethnic and area specificity, and that prenatal diagnosis for high-risk thalassemia carrier pregnant women is an efficient approach to prevent and control the occurrence of severe thalassemia in the high-prevalence areas.

Effect of informationized time tracking management mode on treatment speed of acute ischemic stroke / 第二军医大学学报

Objective To explore the effect of informationized time tracking management mode on the speed of treatment of acute ischemic stroke (AIS). Methods From Aug. 2016 to Jun. 2018, a total of 475 AIS patients receiving intravenous thrombolysis and/or intravascular treatment in Stroke Center of Changhai Hospital of Navy Medical University (Second Military Medical University) were divided into time tracking group (n=291) and non-time tracking group (n=184). The time indicators were compared between the two groups, including onset-to-door time (ODT), door-to-imaging time (DIT), imaging-to-needle time (INT), onset-to-needle time (ONT), imaging-to-puncture time (IPT), onset-to-puncture time (OPT), door-to-needle time (DNT) and door-to-puncture time (DPT). The correlations between ODT and DNT, and ODT and DPT were analyzed using Spearman correlation analysis in the non-time tracking group and the time tracking group. Results The DNT of the patients with intravenous thrombolysis was significantly shorter in the time tracking group than that in the non-time tracking group (27 [23, 36] min vs 33 [23, 43] min, Z=2.123, P<0.05). There was a significant negative correlation between ODT and DNT of the patients with intravenous thrombolysis in the non-time tracking group (r=–0.293, P=0.001), while there was no correlation in the time tracking group (r=–0.034, P=0.723). The ODT and OPT of the patients with endovascular treatment were significantly longer, and DIT was significantly shorter in the time tracking group than those in the non-time tracking group (246 [113, 431] min vs 166 [82, 299] min, 342 [211, 519] min vs 277 [142, 406] min and 18 [14, 23] min vs 26 [16, 34] min; Z=2.667, 2.182 and 4.077, all P<0.05). There was a significant negative correlation between ODT and DPT of the patients with endovascular treatment in the non-time tracking group (r=–0.234, P=0.024), while there was no correlation between ODT and DPT in the time tracking group. (r=–0.056, P=0.424). Conclusion The informationized time tracking management mode can improve the treatment efficiency of acute ischemic stroke and eliminate the influence of ODT on DNT and DPT.

Application of intelligent early warning system in pre- and in-hospital connection of stroke patients / 第二军医大学学报

Objective To explore the value of intelligent early warning system in pre- and in-hospital connection in the treatment of stroke. Methods The clinical data of the patients with suspected stroke, who received treatment and prehospital warning with intelligent early warning system in Stroke Center of Changhai Hospital of Navy Medical University (Second Military Medical University) between Nov. 2017 and Jun. 2018, were retrospectively analyzed. Pre-hospital warning was defined as 120 alerting stroke teams using software before transferring patients to the target hospital. According to the in-hospital treatment methods, the patients were divided into non-stroke group, conservative treatment group, thrombolysis group, thrombectomy group, bridging group and cerebral hemorrhage group. The efficiency in each link of the intelligent early warning system, the ability of emergency doctor diagnosing stroke, the ability of emergency doctor diagnosing severe stroke using gaze-face arm speech time (G-FAST) scale, the speed of first aid response of the attending physician and the door-in-to-door-out (DIDO) time in primary stroke center were evaluated in each group. Results A total of 248 patients were included in this study, including 24 non-stroke patients and 224 stroke patients (101 patients in the conservative treatment group, 23 patients in the thrombolysis group, 32 patients in the thrombectomy group, 22 patients in the bridging group and 46 patients in the cerebral hemorrhage group). The median primary screening time, early warning time and response time of 248 patients were 28.0 (13.0, 92.5), 11.0 (7.3, 15.3) and 19.0 (13.0, 35.0) s, respectively. The sensitivity, specificity, positive predictive value, negative predictive value and accuracy of 6 pre-hospital emergency physicians diagnosing severe stroke using G-FAST scale were 84%, 71%, 83%, 72% and 79%, respectively. Eight patients with severe stroke underwent whole-process monitoring of pre-hospital treatment, and had a median transport time of 113 (82, 142) min and a median DIDO time of 84 (12, 125) min. Conclusion Intelligent early warning system can realize the automation of data acquisition for transfer time points, making the data more comprehensive and reliable. It is helpful to analyze the efficiency of emergency physicians, drivers, stroke teams and primary stroke center in pre- and in-hospital connection in the treatment of stroke, so as to shorten the pre-hospital treatment time and improve the pre-hospital treatment efficiency.

Effect of aortic pulse wave velocity on target organ damage among older patients with type 2 diabetes mellitus / 预防医学

Objective To evaluate the association between aortic arterial stiffness and target organ damage, including renal function decline and left ventricular diastolic dysfunction among elderly diabetic patients and to provide theoretical basis for early prevention and intervention. Methods Brachial-ankle-artery pulse wave velocity(baPWV)reflecting aortic arterial stiffness was observed in 151 diabetic patients with(n=78)or without hypertension(n=73). Clinical data were collected, cardiac structure and function were assessed by echocardiography. Estimated glomerular filtration rate(eGFR)was calculated by CKD-EPI fomula. Results Of 151 subjects, the average age was(75.05±10.13)years and the average baPWV values was (1 803.85±491.04)mm/s. Patients with both diabetes and hypertension had significantly higher baPWV values[(2006.49± 536.70)mm/s]than that of diabetic patients[(1596.96 ±331.02)mm/s, P<0.01]. Multiple linear regression analysis demonstrated that baPWV was negatively associated with E/A ratio and eGFR(β'=-0.249, -0.225, P<0.05), but positively associated with hypertension(β'=2.008, P<0.05). By applying area under the receiver operator characteristic curve, baPWV had powerful predictive power for renal impairment(AUC=0.695, 95% CI: 0.548-0.842)and left ventricular diastolic dysfunction(AUC=0.687, 95%CI: 0.532-0.842). Conclusion Patients with both diabetes and hypertension had significantly higher baPWV values than that of diabetic patients. Higher baPWV was independently associated with greater burden of sub-clinical disease in renal impairment and left ventricular diastolic dysfunction.

Effects of active components in compatible solution of Sparganii Rhizoma-Curcumae Rhizoma on pelvic adhesion in rats with chronic pelvic inflammatory disease / 中成药

AIM To study the influence and action mechanism of effective components in compatible solution of Sparganii Rhizoma-Curcumae Rhizoma on pelvic adhesions of model rats with chronic pelvic inflammatory disease.METHODS Laboratory rats were randomly assigned into six groups,a sham-operated group,a model group,a positive Fukeqianjin tablets group,compatible solution groups (40 g/kg high-dose group,20 g/kg medi um-dose group,and 10 g/kg low-dose group).Except rats of the sham-operated group,those in the other groups were induced into models of chronic pelvic inflammatory disease by mechanical bacterial strain implantation,after which a 20 d corresponding drug administration by oral gavage for each group was initiated.After completion of the last drug administration,Verco criterion was taken as the reference to evaluate pelvic adhesions,HE staining was performed on uterine tissues for pathological scoring,ELASA method was applied to measuring serum IL-1β and TNF-α levels,and Western blot method was used to detect the expression levels of proteins FGF-2 and IGF-1 in uterine tissues.RESULTS Compared with the model group,the high-dose compatible solution group had a much sharper fall in Verco scores (P ＜ 0.05),and remarkably decreased serum IL-1β and TNF-α levels (P ＜ 0.01);both high-dose and medium-dose groups manifested with notably alleviated degenerative necrosis and lowered scores of chronic inflammation infiltration and epithelial hyperproliferation (P ＜ 0.01 or P ＜ 0.05),and a distinct reduction in the expression of proteins FGF-2 and IGF-1 (P ＜ 0.05,P ＜ 0.01).CONCLUSION The significant improvement of the chronic pelvic inflammatory disease in model rats due to the effective components in the compatibile solution of Sparganii Rhizoma-Curcumae Rhizoma may be associated with inhibited release of inflammatory mediators IL-1β and TNF-α,and the reduced expression of proteins FGF-2 and IGF-1 as well.
