Objective: To investigate the changes of cardiovascular health indicator and arteriosclerosis in middle and elder population.
Methods: A total of 4190 subjects with the average age of (49.78 ± 9.74) years by 3 physical examinations in Kailuan group from 2006 to 2011 were randomly stratiifed for arm ankle arterial pulse wave velocity (baPWV) examination. According to 7 AHA cardiovascular health indicators of non-smoking, normal BMI, active excise, healthy diet, normal cholesterol, blood pressure and fasting blood glucose, each indicator had 3 conditions as ideal, general and poor by scores of 2, 1 and 0 respectively. Based on the 1st and 3rd physical examinations, the changes of cardiovascular health scores (△CHS), the subjects were divided into 8 groups as△CHS≤-4,-3,-2,-1, 0, 1, 2 and△CHS≥3, n=241, 368, 611, 855, 911, 647, 354 and 203 respectively. The impacts of△CHS on baPWV values were studied by liner and Logistic regression analyses.
Results: As△CHS increased by △CHS ≤ -4, -3,-2,-1,0,1, 2 and△CHS ≥ 3, the baPWV values were decreased accordingly by cm/s as (1590.78 ± 17.93), (1566.4 ± 14.5), (1552.83 ± 11.25), (1536.59 ± 9.51), (1508.85 ± 9.21), (1499.81 ± 10.93), (1485.92 ± 14.82) and (1475.85 ± 19.57) respectively. Multiple linear regression analysis showed that with adjusted confounding factors, as△CHS increasing 1 score, baPWV increasing 15.58 cm/s (B=15.58, P<0.001). Logistic regression analysis indicated that with adjusted confounding factors, as△CHS increasing 1 score, the risk for arteriosclerosis occurrence was decreased by 14%(OR=0.86, 95%CI 0.83-0.90).
Conclusion: △CHS was negatively related to baPWV in middle and elder subjects, improving cardiovascular health indicator may decrease arteriosclerosis occurrence.

Objective: To explore the predictive value of inlfammatory factors on all cause mortality in normal population.
Methods: In our prospective cohort study, a total of 83,228 subjects from physical examination of Kailuan group from 2006-07 to 2007-10 were enrolled, nobody had acute inlfammation. The death information was collected once per year and the last follow-up was conducted in 2013-12-31. According to baseline levels, white blood cells (WBC), ratio of neutrophil/lymphocyte ratio (N/L) and C-reactive protein (CRP) were respectively divided into 4 Quartile groups; all cause mortality was compared among different groups and their risks were studied by multi-Cox regression analysis.
Results: The average follow-up time was 6.9 years. All cause mortality in Quartile 1, Quartile 2, Quartile 3 and Quartile 4 groups for WBC were 4.2%, 4.5%, 4.5% and 5.0% respectively; for N/L were 3.3%, 3.6%, 4.5% and 6.7% respectively; for CRP were 3.0%, 3.6%, 4.8% and 6.8% respectively. Multi-Cox regression analysis indicated that with adjusted age, gender, waist and other confounders, by elevation of WBC, N/R and CRP, the risks of all cause mortality were increased accordingly, and the risks in Quartile 4 groups were higher than those in Quartile 1 groups as for WBC, it was 1.17-time (95% CI 1.06-1.29);for N/L, it was 1.44-time (95% CI 1.31-1.59); for CRP, it was 1.33-time (95% CI 1.20-1.47) respectively.
Conclusion: Elevated WBC, N/R and CRP are independent risk factors for all cause mortality in normal population.

Objective: To explore the relationship between longitudinal trajectory of systolic blood pressure (SPB) and atrial fibrillation (AF) in Kailuan group population. Methods: Our study cohort consisted of 40727 participants with the specific criteria in Kailuan group, Tangshan. SAS Proc Traj procedure was used to identify longitudinal trajectories of SPB throughout 2006-2007, 2008-2009 and 2010-2011. There were 5 longitudinal trajectories generated: Low-stable group,n=10950, Moderate-stable group, n=19158, Moderate-high stable group,n=3713, High-moderate stable group,n=4702 and High stable group,n=2181. Log-rank test was performed to compare AF incidence throughout 2012-2013 and 2014-2015 by physical examination among different groups; Multi Cox regression analysis was conducted to study the relationship among different SBP longitudinal trajectories and AF occurrence. Results:①The mean age of participants was (51.81±11.54) years including 30693 (75.4%) male.②AF occurrence rates in Low-stable, Moderate-stable, Moderate-high stable, High-moderate stable and High stable groups were 0.1%, 0.2%, 0.5%, 0.5% and 0.6% respectively, allP<0.05.③Multi Cox regression analysis presented that with adjusted confounding factors, compared with the patients in Low-stable group, Moderate-high stable, High-moderate stable and High stable SBP longitudinal trajectories were the risk factors for new AF occurrence (HR=7.58, 95% CI 2.08-27.73), (HR=5.30, 95% CI 1.88-14.95) and (HR=8.52, 95% CI 1.96-37.09) respectively, allP<0.05. With excluded history of myocardial infarction/stroke, the sensitivity study showed the similar result with the major research trend. Conclusion: Elevated long trajectory of SPB was the risk factor for new AF occurrence in Kailuan group population.

ObjectiveTo investigate the influencing factors for the short-term prognosis of patients with HBV-related acute-on-chronic liver failure (HBV-ACLF). MethodsClinical data were collected from 240 HBV-ACLF patients without liver transplantation who were admitted To The Second Affiliated Hospital of Xi’an Jiaotong University from January 2009 to December 2019, and the patients were divided into groups according to survival on days 28 and 90 after admission (28-day survival group with 164 patients and 28-day death group with 76 patients; 90-day survival group with 140 patients and 90-day death group with 100 patients). The data collected included predisposing factors, liver function parameters, Model for End-Stage Liver Disease (MELD) score, MELD combined with serum sodium concentration (MELD-Na) score, and complications. The Mann-Whitney U test was used for comparison of continuous data between two groups, and the chi-square test was used for comparison of categorical data between two groups. The receiver operating characteristic (ROC) curve was plotted to calculate the area under the ROC curve (AUC), and a multivariate logistic regression analysis was used to investigate the risk factors for the short-term prognosis of HBV-ACLF. ResultsThe main predisposing factors of HBV-ACLF included spontaneous activation of HBV (55.6%) and HBV activation caused by the withdrawal of or resistance to nucleoside analogues (25.2%). There were significant differences in age, prothrombin time activity (PTA), neutrophil-lymphocyte ratio (NLR), serum sodium, MELD score, MELD-Na score, and total bilirubin (TBil) at baseline between the 28-day survival group and the 28-day death group (Z=-2.400,-6.015, -5.070, -5.103, -5.044, -7.430, and -6.637, all P＜0.05), and there were also significant differences in age, PTA, NLR, serum sodium, MELD score, MELD-Na, TBil, and cholesterol at baseline between the 90-day survival group and the 90-day death group (Z=-2.205, -7.728, -3.335, -4.015, -6.053, -7.908, -6.655, and -3.607, all P＜0.05). The multivariate logistic regression analysis showed that TBil ＞260.20 mmol/L (odds ratio ［OR］=4.572, 95% confidence interval ［CI］: 1.321-15823, P＜0.05), PTA ＜24.8% (OR=8.934, 95%CI: 3.026-26.374, P＜0.05), NLR＞5.63 (OR=2.632, 95%CI: 1.126-6.152, P＜0.05), serum sodium ＜130.8 mmol/L (OR=27.467, 95%CI: 6.113-123.423, P＜0.05), MELD score ＞17.84 (OR=4.303, 95%CI: 1.048-17.663, P＜0.05), and MELD-Na score ＞25.1 (OR=3.453, 95%CI: 1.614-7.387, P＜0.05) were independent risk factors for 28-day survival; TBil＞260.20 mmol/L (OR=5.148, 95%CI: 1.918-13.822, P＜0.05), PTA ＜25.5% (OR=15.718, 95%CI: 5.161-47.866, P＜0.05), serum sodium ＜135.3 mmol/L (OR=10.080, 95%CI: 3.244-31.323, P＜005), MELD score ＞17.84 (OR=11.157, 95%CI: 2.580-48.254, P＜0.05), MELD-Na score ＞25.1 (OR=4.391, 95%CI: 2057-9.372, P＜0.05) were independent risk factors for 90-day survival. Among the 240 patients, 160 (66.7%) experienced infection within 90 days, among whom 140 had bacterial infection, 12 had viral infection, and 8 had fungal infection. The 160 patients with infection had a significantly higher 90-day mortality rate than the patients without infection (46.3% vs 32.5%, χ2=6.720, P=0.010). Of all 240 patients, 176 had ascites, 44 had pleural effusion, 36 had acute renal injury, 60 had hepatic encephalopathy, and 12 had gastrointestinal bleeding within 28 days, and there were significant differences in the proportion of patients with acute renal injury, grade Ⅲ-Ⅳ hepatic encephalopathy, or gastrointestinal bleeding between the 28-day survival group and the 28-day death group (χ2=64.088，29811，7.797，all P＜0.05). ConclusionTBil, PTA, serum sodium, MELD score, and MELD-Na score at baseline are independent risk factors for the 28- and 90-day prognosis of HBV-ACLF. Liver inflammation and necrosis caused by HBV activation may be the initiating factor for ACLF, and infection, acute renal injury, hepatic encephalopathy, and gastrointestinal bleeding are the main complications affecting the prognosis of patients.

Objective:To detect the expression levels of laboratory of genetics and physiology 2 (LGP2), retinoic acid inducible gene I (RIG-I) and melanoma differentiation associated gene 5 (MDA5) in children with hand, foot and mouth disease (HFMD), and to explore their possible clinical significance in HFMD.Methods:Fifty children with HFMD, who visited Second Affiliated Hospital of Xi′an Jiao Tong University, Xi ′an Children′s Hospital and Xi ′an Central Hospital from May 2020 to May 2021, were selected as the research subjects, and 20 children with physical examination at the same age during the same period were selected as the control group.Children with HFMD were divided into enterovirus 71 (EV-A71) type and coxsackievirus A6 (CV-A6) type according to the results of pathogen detection, and then divided into mild group and severe group according to the severity of the disease.The relative mRNA expression levels of LGP2, RIG-I and MDA5 in each group, and the correlation among the three proteins were compared and analyzed.Results:Among 50 cases of HFMD, 26 cases were EV-A71 type (16 cases were mild and 10 cases were severe) and 24 cases were CV-A6 type (17 cases were mild and 7 cases were severe). There was no significant difference in age and sex between HFMD group and control group ( P>0.05). The relative expression levels of LGP2 mRNA in EV-A71 and CV-A6 HFMD cases were 2.37(1.78, 3.25)% and 1.88 (1.35, 3.13)%, lower than that in control group [2.97(2.61, 3.55)%]. Only the difference between CV-A6 HFMD children and control group was statistically significant ( Z=-2.310, P=0.021). The relative expression levels of RIG-I mRNA in EV-A71 and CV-A6 HFMD cases were 9.95 (7.79, 14.62)% and 9.78(7.04, 15.83)%, lower than that in control group [18.47(13.00, 21.07)%]. The differences were all statistically significant ( P<0.05). The relative expression levels of MDA5 mRNA in EV-A71 and CV-A6 HFMD cases were 4.41(2.82, 5.99)% and 3.98 (2.18, 7.41)%, lower than that in control group [5.10(3.52, 7.71)%], but the differences were not statistically significant.There were no significant differences in the relative expression levels of the three indicators between the mild and severe groups of children with EV-A71 or CV-A6 HFMD.The expression levels of LGP2, RIG-I and MDA5 mRNA were highly correlated( P<0.001). Conclusion:The relative expression levels of LGP2, RIG-I and MDA5 mRNA in children with HFMD are decreased in different degrees than those in normal children.And there is a correlation among them.

Objective:To investigate the expression level of transcription factor dimerization partner 2 (TFDP2) in the placentas of women with preeclampsia, and analyze its effect on the apoptosis of trophoblast cells.Methods:Placental tissues from thirty puerperae with preeclampsia who gave birth by cesarean section in Nanjing Drum Tower Hospital, the Affiliated Hospital of Nanjing University Medical School between January 2018 and December 2022 (preeclampsia group) and 30 healthy puerperae undergoing cesarean section during the same period (control group) were retrospectively selected. Immunohistochemistry was used to localize TFDP2 in the placental tissues. Real-time quantitative-polymerase chain reaction (qRT-PCR) and Western blot were used to detect the differences in expression of TFDP2 at mRNA and protein levels in placental tissues between the two groups. Forskolin-exposed BeWo cells were transfected with small interfering RNA (siRNA) to knockdown TFDP2 and the changes in the expression of apoptosis-related indicators, B cell lymphoma 2 (Bcl2) and Bcl2 associated X (Bax), at protein and mRNA levels were analyzed by Western blot and qRT-PCR, respectively. Besides, the change in the apoptosis level of BeWo cells was detected using terminal deoxynucleotidyl transferase-mediated dUTP nick-end labeling (TUNEL) staining and flow cytometry. Downstream signaling pathways were analyzed to understand the involved molecular mechanisms. Two independent samples t-test, Wilcoxon rank-sum test, and Chi-square test were used for statistical analysis. Results:TFDP2 was mostly localized in the syncytiotrophoblasts and the extravillous trophoblasts in the normal placentas. TFDP2 expression in the syncytiotrophoblasts was lower in the preeclampsia group than in the control group at both mRNA (0.722±0.239 vs. 1.000±0.348, t=3.61, P=0.001) and protein (0.728±0.185 vs. 1.000±0.206, t=2.41, P=0.037) levels. Comparing the group without knockdown of TFDP2, the knockdown of TFDP2 in BeWo cells elevated the Bax/Bcl2 ratio (mRNA: 1.755±0.452 vs. 1.000±0.279, t=3.48, P=0.006; protein: 3.206±0.922 vs. 1.000±0.290, t=3.95, P=0.017), and increased cell apoptosis both in number and ratio (TUNEL staining: 4.556±1.740 vs. 2.444±1.130, t=3.05, P=0.008; flow cytometry: 21.37%±1.66% vs. 12.61%±0.38%, t=8.92, P=0.001). Furthermore, following TFDP2 knockdown, a decrease in the phosphorylation activity of catalytic subunit of protein kinase A (PKAc) at the Thr197 site was observed in the cytoplasm of BeWo cells (0.466±0.035 vs. 1.000±0.075, t=11.19, P<0.001) and a reduction in the expression of β-catenin in the cell nucleus was also detected (0.250±0.093 vs. 1.000±0.269, t=4.57, P=0.010). Conclusion:The expression of TFDP2 decreased significantly in the placentas of patients with preeclampsia, which may promote the apoptosis of syncytiotrophoblasts by inhibiting the PKAc/β-catenin signaling pathway.

OBJECTIVETo evaluate the current feeding status of infants and young children under 2 years old in rural areas of Hubei province.

METHODSThe study was conducted by cluster random sampling from September 2009 to march 2010. The data on breastfeeding and complementary food supplement of the 1 197 infants and young children aged 0-23 months in 8 counties of Hubei province were collected through questionnaires. The feeding status was analyzed according to the WHO 2008 edition of Indicators for assessing infant and young child feeding practices.

RESULTSA total of 1 197 children aged 0-23 months were investigated. The rate of ever breastfeeding of children aged 0-23 months reached up to 93.9% (1 124/1 197), while the percentage of early initiation of breastfeeding was only 22.0% (263/1 197). The rates of exclusive breastfeeding under 6 months, continued breastfeeding for 1 year, and continued breastfeeding for 2 years were 72.1% (277/384), 17.0% (26/153) and 4.9% (7/144), respectively. The median time of giving complementary food was the 6th month and the weaning time was the 9th month. The rate of complementary food supplemented from 6th-8th month in time was 61.8% (444/718) . The rates of minimum dietary diversity, minimum meal frequency, minimum acceptable diet, and consumption of iron-rich or iron-fortified foods among children aged 6-23 months were 61.7% (502/813), 81.5% (663/813), 54.4% (442/813) and 50.1% (407/813), respectively.

CONCLUSIONLate initiation of breastfeeding, non-continued breastfeeding, giving complementary food too early or too late, inadequate category and frequency of complementary food, and the low rate of consumption of iron-rich or iron-fortified foods were the main issues to be concerned on infant feeding in rural areas of Hubei province.

Objective To assess the efficacy of tenofovir disoproxil fumarate (TDF) in chronic hepatitis B (CHB) patients receiving antiviral therapy for three years. Methods A total of 157 CHB patients treated with TDF alone for ≥3 years from January 2015 to August 2020 in the Second Affiliated Hospital of Xi'an Jiaotong University were retrospectively studied. The patients were divided into HBeAg-positive and HBeAg-negative groups based on their baseline HBeAg levels. The data of serum HBV DNA and HBsAg levels at baseline, the first, second and third year of treatment were collected to analyze the dynamic changes. The t -test was used to compare continuous variables with normal distributions between two groups, while the Mann-Whitney U test was used to compare continuous variables with non-normal distribution between two groups. Repeated measurement data with non-normal distribution were first transformed into logarithms and the intra- or between-group comparison was performed using repeated measures analysis of variance. The chi-square test or Fisher exact test was used to compare categorical variables between groups. Results HBV DNA clearance rate in HBeAg-positive patients was significantly lower than that in HBeAg-negative patients during the first and second years of TDF treatment (1st year: 65.8% vs 81.0%, χ 2 =4.676, P < 0.05; 2nd year: 87.7% vs 98.8%, Fisher exact test, P < 0.05). When TDF treatment was given for three years, there was no significant difference in HBV DNA clearance rates (97.3% vs 100%, Fisher exact test, P > 0.05). The baseline HBsAg levels in HBeAg-positive and HBeAg-negative patients were 10 633.6 (2 084.8-24 005.7) IU/mL and 1 402.8 (311.0-2 863.5) IU/mL, respectively, and decreased to 1 534.9 (912.7-5 885.9) IU/mL and 677.8 (119.4-1 974.8) IU/mL after 3 years of TDF treatment, with a significant difference between two groups ( F =25.456, P < 0.001). In HBeAg-positive patients, the median decline value of HBsAg level was significantly higher in the first year [1 856.5 (158.4-12 103.1) IU/mL] than in the second year [879.8 (130.5-2 382.5) IU/mL] or the third year [479.9 (95.0-1 662.4) IU/mL] ( F =10.972, P < 0.001), while there was no significant difference in HBeAg-negative patients ( F =0.513, P > 0.05). In addition, after 3 years of TDF treatment, 59.2% of patients achieved HBsAg < 1500 IU/mL, with a HBsAg negative rate of 1.3%. Conclusion After 3 years of TDF treatment, all HBeAg-negative CHB patients can achieve HBV DNA negative conversion; for HBeAg-positive CHB patients, 97.3% of them achieved HBV DNA negative conversion, while 2.7% of them were still HBV DNA detectable. The HBsAg level declined over treatment time, and the decline rate of HBsAg level in HBeAg positive patients showed a trend of "first fast and then slow". After 3 years of TDF treatment, 59.2% of patients achieved HBsAg < 1500 IU/mL.

In animal experiments, ischemic stroke is usually induced through middle cerebral artery occlusion (MCAO), and quality assessment of this procedure is crucial. However, an accurate assessment method based on 18F-fluorodeoxyglucose (FDG) positron emission tomography (PET) is still lacking. The difficulty lies in the inconsistent preprocessing pipeline, biased intensity normalization, or unclear spatiotemporal uptake of FDG. Here, we propose an image feature-based protocol to assess the quality of the procedure using a 3D scale-invariant feature transform and support vector machine. This feature-based protocol provides a convenient, accurate, and reliable tool to assess the quality of the MCAO procedure in FDG PET studies. Compared with existing approaches, the proposed protocol is fully quantitative, objective, automatic, and bypasses the intensity normalization step. An online interface was constructed to check images and obtain assessment results.
