Abstract
OBJECTIVE To investigate the role of vascular endothelial growth factor (VEGF) in regulating triple-negative breast cancer (TNBC) stem cells and the possible pathways involved in this regulatory mechanism. METHODS The Oncomine database, UALCAN database and Human Protein Atlas (HPA) database were used to analyze the expression of VEGF in breast cancer and its association with the molecular subtypes and prognosis of breast cancer. Sphere formation assay was carried out to examine the effects of hVEGF165 on sphere formation ability of TNBC MDA-MB-231 cell line; Western blotting and RT-qPCR were performed to detect the expression of the tumor stem cell markers including CD44, c-Myc, Nanog, and ALDH1 and the activation of the related pathways. RESULTS Data from the online databases all showed a significant increase of VEGF expression in breast cancer tissues than in the adjacent tissues (P < 0.0001), and its expression level was associated with the molecular subtypes of breast cancer. Specifically, the expression of VEGF was markedly higher in TNBC than in other subtypes of breast cancer. Survival analysis showed that breast cancer patients with a high VEGF expression had a significantly shortened overall survival (P < 0.0001). In the cell experiments, the sphere formation ability of MDA-MB-231 cells was significantly enhanced after treatment with hVEGF165 (P=0.0029). Compared with the monolayer cells, MDA-MB-231 spheres showed significantly increased expressions of VEGF, NRP-1, CD44, Nanog and c-Myc. Treatment with hVEGF165 resulted in significant time-dependent up-regulation of the expressions of CD44, c-Myc, Nanog and ALDH1 and down-regulation of CD24 expression in the cells. The results of Western blotting demonstrated that treatment with hVEGF165 caused significant activation of the ERK/MAPK pathway in MDA-MB-231 cells. CONCLUSION VEGF promotes cancer stemness of triple-negative breast cancer possibly through the ERK/MAPK pathway.

Abstract
Abstract
Objective
To investigate the relationship between admission diastolic blood pressure (DBP) and subsequent cardiovascular and all-cause mortality in elderly patients with acute coronary syndrome (ACS).
Methods
This is a retrospective observational study. Consecutive patients ≥65 years of age admitted for ACS at a 2,300-bed tertiary hospital from December 2012 to July 2019 were included. The association between admission DBP and cardiovascular and all-cause mortality during hospitalization and over the follow-up period among this population were analyzed using multivariate COX regression model. Results were presented according to DBP quartiles: Q1, less than 67 mm Hg; Q2, from 67 to 72 mm Hg; Q3, from 73 to 80 mm Hg; and Q4, above 80 mm Hg.
Results
A total of 6 785 patients were included in this cohort study. Mean (SD) patient age was 74.0 (6.5) years, and 47.6% were women. Mean (SD) follow-up time was 2.54 (1.82) years. A non-linear relation was observed between DBP at admission and cardiovascular and all-cause mortality during hospitalization and over the follow-up period using restricted cubic splines. After adjustment for potential confounders, patients in Q3 or Q2 had lower risk for 2-year cardiovascular death by Cox proportional hazard model compared with patients in Q4 (hazard ratio [HR] 0.66; 95% confidence interval [CI], 0.48–0.90, P=0.010, for Q3 vs Q4; and HR 0.72; 95% CI, 0.53–0.99, P=0.041, for Q2vs Q4), while patients in Q1 had similar risk for cardiovascular death with that of patients in Q4. Meanwhile, when compared with patients in Q1, patients in Q3 had lower risk for 2-year cardiovascular death (HR, 0.72; 95% CI, 0.53–0.97, P=0.033). However, lower or higher admission DBP was not an independent predictor of 2-year all-cause mortality in this population.
Conclusion
Among patients aged ≥65 years admitted for ACS, there is a J-curve relationship between supine admission DBP and risk for 2-year cardiovascular death, with a nadir at 73–80 mm Hg.

Abstract
Abstract
Background and aims
The present study aimed to develop and validate separate risk prediction models for thrombosis events (TEs) and major bleeding (MB) in patients with multi-vessel coronary artery lesions who had undergone primary percutaneous coronary intervention (PCI).
Methods and results
TEs were defined as the composite of myocardial infarction recurrence or ischemic cerebrovascular events, whereas MB was defined as the occurrence of bleeding academic research consortium (BARC) 3 or 5 bleeding. The derivation and validation cohorts comprised 2976 patients who underwent primary PCI between January 2010 and June 2017. At a median follow-up of 3.07 years (1122 days), TEs and MB occurred in 167 and 98 patients, respectively. Independent predictors of TEs were older age, prior PCI, non-ST elevated MI (NSTEMI), and stent thrombosis (ST). Independent predictors of MB were triple therapy at discharge, coronary artery bifurcation lesions, lesion restenosis, target lesion of the left main coronary artery, and PTCA. In the derivation and validation cohorts, the areas under the curve were 0.817 and 0.820 for thrombosis and 0.886 and 0.976 for bleeding, respectively. In the derivation cohort, high thrombotic risk (n=755) was associated with a higher 3-year incidence of TEs, major adverse cardiovascular events (MACEs), and all-cause death, compared to low risk (n=1275) (p=0.0022, 0.019, 0.012, respectively). High bleeding risk (n=1675) was associated with a higher incidence of bleeding, MACEs, cardiac death, compared to low risk (n=355) (p<0.0001).
Conclusion
Simple risk scores can be useful in predicting the risks of ischemic and bleeding events after primary PCI, thereby stratifying thrombotic or MB risks and facilitating clinical decisions.

Abstract
Abstract
Background
At present, it is worth noting that there is a lack of biomarker for the residual risk of thrombosis in patients underwent percutaneous coronary intervention (PCI). D-dimer is an important thrombus marker and widely used in clinical practice.
Purpose
We aim to investigate the correlation between D-dimer and the risk of stent thrombosis (ST) after PCI.
Method
This is a prospective, observational study of 10,724 patients who underwent PCI. The primary endpoint was ST, which was defined according to the Academic Research Consortium including definite, probable, and possible.
Results
Finally, 8565 patients were included in this study after excluding 2159 people with missing D-dimer data or lost to follow-up. After 2-year follow-up, there were 77 ST occurred. D-dimer levels were significantly higher in the ST group (0.33 [0.28, 0.56] μg/ml) than in the non-ST group (0.28 [0.20, 0.41] μg/ml) (P=0.001). Kaplan–Meier survival curve analysis showed that patients with high D-dimer levels had higher cumulative ST according to the median D-dimer level (0.28 μg/ml) in the total population, acute coronary syndrome (ACS) subgroup, and stable coronary artery disease (SCAD) subgroup, respectively. (log-rank test, all P<0.001) (Figure 1). After multivariate-adjusted cox hazard analysis, high D-dimer levels (≥0.28 μg/ml) were significantly associated with ST in the total population (hazard ratio [HR]: 2.25, 95% confidence interval [CI]: 1.29–3.95, P=0.005) and ACS subgroup (HR: 2.13, 95% CI: 1.09–4.16, P=0.027); however, we did not find a statistically significant in the SCAD subgroup (HR: 2.56, 95% CI: 0.92–7.1, P=0.072).
Conclusion
In this real world and large sample data study, we reported for the first time that D-dimer was strong independent thrombosis biomarker in patient who underwent PCI. In the future, we may use D-dimer to guide individualized antithrombotic therapy after PCI.

Abstract
Abstract
Background
Management of dyslipidemia is the primary recommend in current guidelines in patients with coronary heart disease (CHD). Despite intense statins therapy, patients with low-density lipoprotein cholesterol (LDL-C) level of more than 1.8 mmol/L still have residual cholesterol risk. Premature triple-vessel disease (PTVD) is a severe CHD. Recent studies have established that both residual cholesterol risks and PTVD were associated with adverse cardiovascular events. Niemann-Pick C1-like 1 (NPC1L1) and 3-hydroxy-3-methylglutaryl-coenzyme A reductase (HMGCR) is involved in exogenous cholesterol absorption and endogenous cholesterol synthesis respectively, which play a vital part on dyslipidemia.
Purpose
The present study aimed to investigate the association between NPC1L1 and HMGCR gene polymorphisms and residual cholesterol risk in patients with PTVD.
Methods
A total of 609 PTVD patients treated with statins were consecutively enrolled from April 2004 to February 2011. Residual cholesterol risk was defined as low-density lipoprotein cholesterol (LDL-C) >1.8 mmol/L. According to LDL-C levels, the patients were divided into two groups: residual cholesterol risk group (n=521, >1.8 mmol/L) and non-residual cholesterol risk group (n=88, LDL-C ≤1.8 mmol/L). Four single nucleotide polymorphisms (SNP) of NPC1L1 gene including rs11763759, rs4720470, rs2072183 and rs2073547 and three SNPs of HMGCR gene including rs12916, rs2303151 and rs4629571 were genotyped.
Results
After adjusted for age and sex, multivariate logistic regression analysis showed that rs12916 of HMGCR gene was associated with 2.082 times higher residual cholesterol risk in recessive model (OR: 2.082, 95% CI: 1.156–3.749, P=0.015), and the homozygous TT of rs12916 (OR: 2.262, 95% CI: 1.155–4.429, P=0.017) was associated with 2.262 times higher residual cholesterol risk in codominant model while there was no significant association for the heterozygous CT of rs12916 in codominant model (OR: 1.140, 95% CI: 0.678–1.917, P=0.621). There was no significant association between the SNPs of NPC1L1 gene and residual cholesterol risk in various models (P>0.05).
Conclusions
We reported for the first time that the rs12916 on HMGCR gene were associated with residual cholesterol risk in patients with PTVD, providing new insight in genetic treatment in dyslipidemia.

Abstract
Abstract
Background
Metabolic syndrome is associated with increased incidence of diabetes and cardiovascular diseases in patients initially free from these diseases. However, its prognostic value in patients with established coronary artery diseases remains controversial.
Purpose
Therefore, we aimed to illustrate the prevalence and investigate the impact of metabolic syndrome in patients with multivessel coronary artery disease and acute coronary syndrome.
Methods
We conducted a large registry of consecutive patients with acute coronary syndrome referred to primary percutaneous coronary intervention and those with multivessel diseases were eligible for this analysis. Metabolic syndrome was defined using modified criteria based on the Adult Treatment Panel III definition from the National Cholesterol Education Program. The primary outcome was major adverse cardiovascular events (MACE), a composite of all-cause death, myocardial infarction, and stroke.
Results
A total of 2532 patients were included in current analysis and 993 (39.2%) of them had metabolic syndrome while 1539 (60.8%) did not. The prevalence of metabolic syndrome increased over the study period (p for trend = 0.005). There was a significant decline of metabolic syndrome prevalence in patients over 60 years old (p for trend = 0.002) and females had a higher prevalence than their male counterparts (61.5% verse 32.9%, p<0.001). Over a median follow-up of 2.3 years, metabolic syndrome was not significantly associated with MACE (adjusted 95% CI 0.92 to 1.54). In addition, there was no significant difference observed between two groups in other individual outcomes, namely all-cause death, cardiac death, stroke, myocardial infarction, and any revascularization.
Conclusions
Metabolic syndrome was frequently observed in patients with multivessel coronary artery disease and acute coronary syndrome. Patients with metabolic syndrome were more likely to be young and female. However, it was not an independent predictor for MACE after primary percutaneous coronary intervention in those patients.

Abstract
Suboptimal diet is one of the most important controllable risk factors for non-communicable diseases. However, randomized controlled trials make it difficult to quantify the causal association between specific dietary factors and health outcomes. In recent years, the rapid development of causal inference has provided a robust theoretical and methodological tool for making full use of observational research data and producing high-quality nutritional epidemiologic research evidence. The causal graph model visualizes the complex causal relationship system by integrating a large amount of prior knowledge and provides a basic framework for identifying confounding and determining causal effect estimation strategies. Different analysis strategies such as adjusting confounders, instrumental variables, or mediation analysis can be created based on other causal graphs. This paper introduces the idea of the causal graph model and the characteristics of various analysis strategies and their application in nutritional epidemiology research, aiming to promote the application of the causal graph model in nutrition and provide references and suggestions for the follow-up research.

Abstract
Huntington disease (HD) is a single-gene autosomal dominant inherited neurodegenerative disease caused by a polyglutamine expansion of the protein huntingtin (HTT). Huntingtin-associated protein 1 (HAP1) is the first protein identified as an interacting partner of huntingtin, which is directly associated with HD. HAP1 is mainly expressed in the nervous system and is also found in the endocrine system and digestive system, and then involves in the occurrence of the related endocrine diseases, digestive system diseases, and cancer. Understanding the function of HAP1 could help elucidate the pathogenesis that HTT plays in the disease process. Therefore, this article attempts to summarize the latest research progress of the role of HAP1 and its application for diseases in recent years, aiming to clarify the functions of HAP1 and its interacting proteins, and provide new research ideas and new therapeutic targets for the treatment of cancer and related diseases.

Abstract
Objective To assess the current status of caesarean delivery (CD) in China, propose reference CD rates for China overall, and by regions, investigate the main indications for CDs and identify possible areas for safe reduction. Design A multicentre cross‐sectional study. Setting A total of 94 hospitals across 23 provinces in China. Population A total of 73 977 randomly selected deliveries. Methods We used a modified Robson classification to characterise CDs in subgroups and by regions, and the World Health Organization (WHO) C‐Model to calculate reference CD rates. Main outcome measures CD rates in China. Results In 2015–2016, the overall CD rate in China was 38.9% (95% CI 38.6–39.3%). Considering the obstetric characteristics of the population, the multivariable model‐based reference CD rate was estimated at 28.5% (95% CI 28.3–28.8%). Accordingly, an absolute reduction of 10.4% (or 26.7% relative reduction) may be considered. The CD rate varied substantially by region. Previous CD was the most common indication in all regions, accounting for 38.2% of all CDs, followed by maternal request (9.8%), labour dystocia (8.3%), fetal distress (7.7%) and malpresentation (7.6%). Overall, 12.7% of women had prelabour CDs, contributing to 32.8% of the total CDs. Conclusions Nearly 39% of births were delivered by caesarean in China but a reduction of this rate by a quarter may be considered attainable. Repeat CD contributed more than one‐third of the total CDs. Given the large variation in maternal characteristics, region‐specific or even hospital‐specific reference CD rates are needed for precision management of CD. Tweetable abstract The caesarean rate in 2015–2016 in China was 38.9%, whereas the reference rate was 28.5%. The caesarean rate in 2015–2016 in China was 38.9%, whereas the reference rate was 28.5%.

Abstract
OBJECTIVE The aim of this study was to investigate the influences of propofol on intestinal ischemia/reperfusion (I/R) injury in rats through the p38 mitogen-activated protein kinase (MAPK)/nuclear factor-kappa B (NF-κB) signaling pathway. MATERIALS AND METHODS The models of intestinal I/R injury were first successfully established. All rats were randomly divided into 4 groups, namely, S group, I/R group, P group and P + S group. Pathological-morphological changes, injury score and wet-to-dry weight ratio of intestinal tissues as well as oxidative stress indexes in each group of rats were detected. Enzyme-linked immunosorbent assay (ELISA) was applied to measure the levels of inflammatory factors such as creatine kinase-MB (CK-MB), tumor necrosis factor-alpha (TNF-α) and interleukin-6 (IL-6) in each group of rats. Furthermore, Western blotting (WB) assay was applied to determine the protein expression levels of p38 MAPK and NF-κB in different groups. RESULTS Intestinal tissue injury was the severest in I/R group, with the infiltration of massive inflammatory cells and oozing of blood (Figure 1A, I/R). Compared with those in I/R group, the infiltration of inflammatory cells and damage to intestinal villi were notably relieved in P group and P + S group, revealing that the intestinal mucosal injury was remarkably repaired in P group and P + S group (Figure 1A, P). Moreover, the intestinal tissue injury score was evidently higher in I/R group, P group and P + S group than that in S group (p<0.05). However, it was markedly lower in P group and P + S group than that in I/R group (p<0.05). I/R group, P group and P + S group exhibited significantly increased wet-to-dry weight ratio of intestinal tissues in comparison with S group (p<0.05). However, P group and P + S group exhibited distinctly lower wet-to-dry weight ratio of intestinal tissues than I/R group (p<0.05). The content of malondialdehyde (MDA) was reduced prominently, while that of superoxide dismutase (SOD) was elevated significantly in P group and P + S group in contrast with those in I/R group (p<0.05). On the contrary, P + S group displayed remarkably lower MDA content and higher SOD content than P group (p<0.05). The levels of CK-MB, TNF-α and IL-6 in the blood rose markedly in I/R group compared with those in S group (p<0.05). However, they declined evidently in P group and P + S group in contrast with those in I/R group (p<0.05). Besides, the protein expression level of phosphorylated p38 MAPK was significantly higher in I/R group, P group and P + S group than that in S group (p<0.05). However, no significant difference was observed in the protein expression of total p38 MAPK among the four groups (p>0.05). However, the protein expression level of phosphorylated p38 MAPK was distinctly down-regulated in P group and P + S group in comparison with that in I/R group (p<0.05). Finally, I/R group, P group and P + S group had a prominently higher protein expression level of NF-κB than S group (p<0.05). However, P group and P + S group exerted a significantly lower protein expression level of NF-κB than I/R group (p<0.05). CONCLUSIONS Propofol decreases the release of inflammatory factors and alleviates intestinal edema by inhibiting the p38 MAPK/NF-κB signaling pathway, thereby mitigating and treating the intestinal I/R injury in rats.

Abstract
Objective: To analyze the intensity and epidemiological characteristics of hepatitis B virus (HBV) reactivation among inactive HBsAg carriers (IHC) of rural areas in Ji'nan. Methods: In 2018 and 2020, follow-up investigations were conducted on IHC identified in the population physical examination in Zhangqiu district of Ji'nan. The results of the two follow-up visits were compared to analyze the incidence and distribution characteristics of HBV reactivation in IHC at the community level. Results: A total of 424 IHC completed two follow-up visits, and 47 cases of HBV reactivation were found, the cumulative reactivation rate was 11.08%, and the incidence density was 5.46/100 person-years. Multivariate analysis showed that gender, age, smoking, drinking , family history of liver disease and chronic diseases were not associated with HBV reactivation (P>0.05), and baseline HBV DNA load was associated with reactivation (P<0.05), in the HBV DNA level ≥1 000 IU/ml group, the reactivation rate could reach 18.92%. After reactivation, the mean level of ALT increased from baseline and the abnormal rate increased, liver function tended to be abnormal in reactivated patients. 4 (8.51%) reactivators had hepatitis, and 1 (2.13%) had jaundice hepatitis. Conclusions: The incidence of HBV reactivation was higher among IHC in rural communities in Ji'nan. Most of the reactivators were asymptomatic or mildly reactivated. Follow-up of inactive HBsAg patients should be strengthened and changes in ALT and HBV DNA levels should be closely monitored.

Abstract
Non-occupational post-exposure prophylaxis (nPEP), a biological means to block the transmission of HIV, is recommended by European countries, USA and WHO to use in HIV high-risk groups, but its utilization rate is still very low. The information-motivation-behavioral skills model (IMB) can accurately explain the prevalence and change of health behaviors. Based on this model, this paper summarizes the progress in research of the influencing factors for nPEP use to provide a basis for further research to promote the use of nPEP.
