Abstract
OBJECTIVE To explore the correlations between the degree of coronary artery stenosis with blood lipid, C-reactive protein (CRP), homocysteine (Hcy), gamma-glutamyl transpeptidase (GGT), soluble cluster determinant 36 (sCD36), and fibrinogen (Fib) levels in elderly patients with coronary heart disease. PATIENTS AND METHODS The Gensini scores for the coronary artery stenosis were analyzed in patients with single-vessel, double-vessel, and multi-vessel coronary artery diseases in observation group and normal people in control group. Changes in blood lipid-associated parameters, including total cholesterol (TC), triacylglycerol (TG), low-density lipoprotein cholesterol (LDL-C), and high-density lipoprotein cholesterol (HDL-C), CRP, Hcy, GGT, sCD36, and Fib were compared between the two groups. The correlations between the Gensini score with changes of the blood-associated parameters, CRP, Hcy, GGT, sCD36, and Fib were analyzed. Finally, univariate and multivariate logistic regression analyses were conducted to determine the risk factors for coronary artery stenosis in elderly patients with coronary heart disease. RESULTS The Gensini score was significantly higher in coronary heart disease patients with multi-vessel, double-vessel, and single-vessel coronary artery diseases compared with that in normal people (p<0.05). The levels of the blood lipid-associated parameters TC, TG, and LDL-C in observation group were substantially higher than those in control group (p<0.05), and the level of HDL-C was notably lower than that in control group (p<0.05). Subjects in observation group had markedly higher levels of CRP, Hcy, GGT, sCD36, and Fib than control group (p<0.05). The Gensini score for the degree of coronary artery stenosis was positively correlated with the levels of the blood lipid-associated parameters TC and TG, CRP, Hcy, GGT, sCD36, and Fib (p<0.05) and negatively associated with the level of HDL-C (p<0.05). Blood lipid-associated parameters, CRP, Hcy, GGT, sCD36, and Fib were the independent risk factors for coronary artery stenosis in elderly patients with coronary heart disease patients. CONCLUSIONS The elevations of blood lipid, CRP, Hcy, GGT, sCD36, and Fib levels are closely associated with coronary artery stenosis, and serve as the independent risk factors for coronary artery stenosis.

Abstract
BACKGROUND: Occupational exposure-related risk of Mycobacterium tuberculosis infection has been reported for village doctors in China. This prospective study aims to estimate the infection acquisition in this key population.METHODS: At baseline, all village doctors registered in Zhongmu County were tested by QuantiFERON®-TB Gold In-Tube (QFT) and QuantiFERON®-TB Gold Plus (QFT-Plus) in parallel. Those negatives for either of the tests were retested to identify conversions at the 2-year follow-up investigation.RESULTS: A total of 367 eligible participants completed the 2-year follow-up survey with frequency of conversion of 5.0% (18/361) for QFT and 6.1% (21/343) for QFT-Plus. The agreement of follow-up results between the tests was 93.2% with a κ coefficient of 0.43 (95%CI 0.20-0.65). Among QFT-Plus convertors, the difference between TB1 and TB2 tubes (TB2-TB1) was significantly increased as compared with baseline results (P = 0.039). Participants from the villages with occurrence of microbiologically confirmed pulmonary TB showed higher frequency of QFT conversions (11.0% vs. 3.2%, P = 0.011) and QFT-Plus conversions (12.3% vs. 4.4%, P = 0.027) than those from the villages without occurrence.CONCLUSION: Our results consistently suggest that capability on occupational protection and M. tuberculosis infection control should be improved in village doctors in China.

Abstract
Abstract
Background
Brugada syndrome (BrS) is an inherited disease which causes fatal arrhythmias and sudden cardiac death. Mutations in SCN5A gene, which encoding cardiac sodium channel (NaV1.5), are the most common genotype of BrS patients. Some SCN5A-related variants were reported to retain NaV1.5 in endoplasmic reticulum (ER) due to trafficking deficiency. MOG1 was previously reported to interact with NaV1.5 and increased sodium current (INa) through enhancing the trafficking. However, its molecular mechanisms are still unclear. Coat protein complex II (COPII) is responsible for the ER to Golgi transport. Sec23 forms the inner coat of COPII and participates in cargo proteins selection.
Purpose
To demonstrate that MOG1 rescues SCN5A-related variants by enhancing the forward trafficking through Sec23a-NaV1.5 interaction.
Methods
Site directed mutagenesis, immunofluorescence staining, biotinylation assay, Western blot analysis and whole-cell patch clamp recording were used. CRISPR/Cas9 was used to knock out Sec23a expression in HEK293 cells.
Results
We found that SCN5A-p.R104W was characterized as reduced NaV1.5 level and lack of INa. The variant SCN5A-p.R104W was mainly distributed in ER. MOG1 could rescue the total and surface expression of SCN5A-p.R104W but could not restore INa (Figure 1a). Considering that most patients are heterozygous, co-transfection of SCN5A-WT and SCN5A-p.R104W were obtained. We found MOG1 could increase both NaV1.5 level and INa of heterozygous expressed SCN5A-p.R104W. We further revealed an interaction between NaV1.5 and Sec23a by co-immunoprecipitation (Co-IP) assay. The interaction between NaV1.5 and Sec23a was increased by MOG1, which indicates that Sec23a participates in MOG1-mediated increase in NaV1.5 level (Figure 1b). Knockout of Sec23a reduced cell surface, but not total, NaV1.5 level (Figure 1c and 1d). Next, the Sec23a knockout HEK293 cells were co-transfected with SCN5A-p.R104W and pcDNA3 or MOG1. MOG1 could not increase SCN5A-p.R104W protein level in Sec23a knockout cells.
Conclusion
Our data demonstrated a novel mechanism that MOG1 restores the expression and function of SCN5A-p.R104W by enhancing its forward trafficking through Sec23a-NaV1.5 interaction.

Abstract
Abstract
Background
While mitral annular calcification (MAC) is associated with valvular regurgitation or stenosis, this disease entity remains poorly understood.
Purpose
We sought to evaluate the prevalence and outcomes of patients with MAC.
Methods
Between January 2014 and December 2015, we reviewed all patients who underwent transthoracic echocardiography (TTE), and were identified as having MAC with either mitral regurgitation (MR) or stenosis (MS). Medical records were manually examined for demographics, morbidities, type and severity of mitral disease, and clinical outcomes for this cohort.
Results
Of 41,136 patients who had undergone TTE, MAC was identified in 2,855 (6.9%) patients, including 434 (1.0%) patients who had significant concomitant MR or MS (mean age, 78.9±10.4 years; 63% women). Severe heart failure (NYHA III or IV, 37%), renal failure (mean GFR, 47.3±15.7 ml/min), aortic stenosis (26% with severe stenosis or prior aortic intervention), diabetes (35%), and atrial fibrillation (50%) were common. The mean mitral gradient was 6.2±3.0 mmHg. Fifty-eight patients (13%) underwent surgical or transcatheter mitral valve intervention, with two procedural deaths (3.4%). Overall, the 3-year survival free of all-cause mortality was 53.9%, while freedom from all-cause mortality, hospitalization for heart failure, myocardial infarction and cerebrovascular accident was only 26.5% (Figure 1). Three-year survival free of all-cause mortality for those who had surgery or transcatheter therapy was better in comparison to those treated medically (77.6% vs. 50.3%; p<0.001).
Conclusions
Patients with MAC with MR or MS are common, have severe co-morbidities, and have poor long-term survival. Further study is needed to improve the clinical outcomes of these patients.

Abstract
Abstract
Background
Obstructive sleep apnea (OSA) is closely related to the incidence and progression of coronary artery disease (CAD), but the mechanisms linking OSA and CAD are unclear. C1q/TNF-related protein-9 (CTRP9) is a novel adipokine that protects the heart against ischemic injury and ameliorates cardiac remodeling.
Purpose
We aimed to ascertain the clinical relevance of CTRP9 with OSA prevalence in patients with CAD.
Methods
From August 2016 to March 2019, consecutive eligible patients with CAD (n=154; angina pectoris, n=88; acute myocardial infarction [AMI], n=66) underwent cardiorespiratory polygraphy during hospitalization. OSA was defined as an apnea-hypopnea index (AHI) ≥15 events h–1. Plasma CTRP9 concentrations were measured by ELISA method.
Results
OSA was present in 89 patients (57.8%). CTRP9 levels were significantly decreased in the OSA group than in the non-OSA group (4.7 [4.1–5.2] ng/mL vs. 4.9 [4.4–6.0] ng/mL, P=0.003). The difference between groups was only observed in patients with AMI (3.0 [2.3–4.9] vs. 4.5 [3.2–7.9], P=0.009), but not in patients with AP (5.0 [4.7–5.3] ng/mL vs. 5.1 [4.7–5.9] ng/mL, P=0.571) (Figure 1). Correlation analysis showed that CTRP9 levels were negatively correlated with AHI (r=−0.238, P=0.003) and oxygen desaturation index (r=−0.234, P=0.004), and positively correlated with left ventricular ejection fraction (r=0.251, P=0.004) in all subjects. Multivariate analysis showed that male gender (OR 3.099, 95% CI 1.029–9.330, P=0.044), body mass index (OR 1.148, 95% CI 1.040–1.268, P=0.006), and CTRP9 levels (OR 0.726, 95% CI 0.592–0.890, P=0.002) were independently associated with the prevalence of OSA.
Conclusions
Plasma CTRP9 levels were independently related to the prevalence of OSA in patients with CAD, suggesting that CTRP9 might play a role in the pathogenesis of CAD exacerbated by OSA.

Abstract
Abstract
Background
The phenomenon of size-mismatches between cylindrical stents and tapered vessels is not uncommon in current endovascular interventions which is associated with poor clinical outcomes.
Purpose
The aim of the present study was to evaluate the mechanical properties of the novel conic BRS and to validate its performance with the support of optical coherence tomography (OCT), quantitative coronary angiography (QCA) and histology up to 2 years in a porcine model.
Methods
We produced the conical BRS with the four-axis 3D printing system, with a computer-controlled rotational axis (the 4th axis) in addition to the 3 axes of traditional 3D printing systems.
Mechanical properties were evaluated by recoil and radial strength, cyclic fatigability testing.
Twelve swine that received 12 conic BRS were evaluated by OCT, QCA and histology post-implantation and at 12 and 24 months.
Results
The in vitro study showed no fractures after accelerated cycle testing over time (at 3.8×108 cycles).
The recoil rate of the scaffolds after plate compress test was 14.3±0.61%.
There was no significant peri-operative complications.
By OCT, 60±21 struts per BRS were recognizable by 2 years. Quantitative coronary angiography showed late luminal loss and percent diameter stenosis were 0.02±0.52 mm and 0.50±16.90% at 2-year follow-up.
Histopathological analysis demonstrated mild vessel injuries, inflammatory cell infiltration around struts at 1 and 2 years follow ups.
Conclusions
The conical BRS showed optimal performance and has the potential to improve clinical outcome.

Abstract
OBJECTIVE Papillary thyroid carcinoma (PTC) is the most common type of thyroid malignancy with physiological microRNA (miR) pathomorphological changes. MiR-548c-3p participates in multiple processes of tumor development and progression. However, the role of miR-548c-3p in PTC and the underlying mechanisms remain undefined. Therefore, this study aimed to detect the expression of miR-548c-3p in PTC and to explore its exact function. MATERIALS AND METHODS MiR-548c-3p expression was analyzed in PTC tissue and cell lines by Real-Time fluorescence quantitative Polymerase Chain Reaction. Colony formation and cell viability assay were used to measure cell proliferation. Wound healing assay and transwell invasion assay were conducted to examine cell migration and invasion. The protein expression of the signaling pathways was determined by Western blot analysis. RESULTS Our results indicated that miR-548c-3p was downregulated in PTC tissues and cell lines. Moreover, miR-548c-3p mimics suppressed PTC cell viability, colony formation, cell migration, and invasion capacity. Low expression of miR-548c-3p significantly enhanced N-cadherin and vimentin expression. A negative correlation was determined between miR-548c-3p and hypoxia-inducible factor (HIF) 1α or vascular endothelial growth factor (VEGF) levels, indicating that miR-548c-3p inhibited tumor progression by suppressing the HIF1α-mediated VEGF signaling pathway. CONCLUSIONS MiR-548c-3p could suppress PTC progression by inhibiting the HIF1α-mediated VEGF signaling pathway.

Abstract
AIMS RpoE is quite immunogenic and can be used as a candidate vaccine for Streptococcus suis infection via immunoproteomics as reported in our previous studies. In this study, we aimed to verify the immunogenicity of recombinant RpoE and its protective effect against of S. suis. METHODS AND RESULTS The RpoE protein was successfully expressed in Escherichia coli, and the purified recombinant protein was mixed with ISA206 to prepare an S. suis subunit vaccine. Mice were immunized with the RpoE subunit vaccine and then infected with the virulent S. suis strain ZY05719. Subunit vaccine-immunized mice achieved 50% protection, less pathological damage and less bacterial distribution in each organ compared with the control mice. Furthermore, in vitro culture, showed that mouse antisera significantly (P < 0·001) inhibited the growth of S. suis, and qRT-PCR results showed that RpoE successfully induced the up-regulation of IL-6 and TNF-α cytokines. CONCLUSIONS RpoE mice were vaccinated to obtain immune protection, which may be candidates for S. suis subunit vaccine. SIGNIFICANCE AND IMPACT OF THE STUDY The results of this study will provide new ideas for the development of safe and effective recombinant subunits vaccines for S. suis.

Abstract
Abstract
Background
Patient-assessed quality of chronic illness care is important to guide medical care for patients with diabetes and other complex chronic diseases, but information from epidemiological studies is scarce. Thus, we examined self-assessed quality of care among adults with type 2 diabetes (T2D) based on a population-based design.
Methods
The study population was drawn from a nationwide survey on diabetes-related knowledge and information needs conducted in Germany in 2017 and included participants aged ≥18 years with known type 2 diabetes (T2D) in the last 12 months (n = 1,328). A German short version of the “Patient assessment of chronic illness care (PACIC-DSF)” consisting of 9 items based on 5-point Likert scale was applied to assess self-reported quality of care in diabetes which was operationalized by a standardized PACIC sum score ranging from 1 to 5. Linear regression with different stages of adjustment was applied to assess the association of basic characteristics and diabetes-related factors with the PACIC score.
Results
Quality of care was assessed less favorably by women than by men (PACIC score: 2.38 vs. 2.47) overall and decreased along with age. The PACIC score significantly increased in participants with insulin use (β = 0.16, p = 0.024), ever participating in a diabetes education program (β = 0.33, p < 0.001), following a diet plan at least once a week (β = 0.33, p < =0.001) as well as performing daily self-examination of feet (β = 0.14, p = 0.023), self-control of blood glucose (β = 0.34, p < 0.001), and being physically active for at least 30 min (β = 0.21, p < 0.001) compared to participants without the respective trait.
Conclusions
Self-assessed quality of care by adults with known T2D from this population-based study is moderate and seems lower compared to findings from clinical studies.
Key messages
An active involvement of people with type 2 diabetes into the implementation of care is essential and may contribute to improved self-perceived quality of care. To identify and overcome obstacles in diabetes care based on the patient’s perspective remains a public health challenge.

Abstract
Abstract
Background
While life expectancy (LE) is rising, years lived with severe health impairments especially due to chronic diseases also increase. Diabetes is one of the major chronic diseases with high potential for co-morbidity and premature deaths needing life-long care. Therefore, information about loss in LE and healthy life years (HLY) in people with diabetes compared to people without diabetes is essential for assessing the burden of diabetes.
Methods
Data on all-cause mortality rates for the general population of Germany in 2014 was drawn from the Federal Statistical Office; mortality rate ratios for people with diabetes compared to people without diabetes were based on claims data from about 70 million people covered by statutory health insurances in 2014. Data of three nationwide health telephone surveys conducted among adults in Germany 2009-2012 (n ∼ 60,000) were used to assess severe health impairments defined as self-reported limitations in daily activities due to diseases for at least six months in people with and without diabetes. Based on these figures, estimates on LE and HLY could be calculated by sex and 5-year age-groups for people with and without diabetes aged ≥ 30 years.
Results
In both sexes and in all 5-year age-groups, LE and HLY were substantially lower for people with than for people without diabetes. For example, among women in the age group 30-34 years, LE and HLY estimates were 48.0 and 36.4 years for those with diabetes compared to 54.9 and 47.6 years for those without diabetes; in men, these figures were estimated as 42.6 and 32.4 years for those with diabetes compared to 50.3 and 44.1 years for those without diabetes. Differences in LE and HLY between people with and without diabetes attenuated with increasing age.
Conclusions
The present study revealed substantial reductions in LE and HLY related to diabetes and underlines the importance of integrating both figures in a national diabetes surveillance.
Key messages
There are substantial differences in life expectancy and healthy life years between people with and without diabetes. Specific intervention and prevention activities should be implemented to tackle disability in persons with diabetes.

Abstract
Abstract
Background
Non-communicable diseases (NCD) are a major public health challenge in Germany and throughout the world. The epidemiology of diabetes, in particular type 2 diabetes, exemplifies the need for effective prevention and control. To support policy making with actionable evidence, the Robert Koch Institute (RKI) is developing a diabetes surveillance system for Germany serving as model for NCD surveillance.
Methods
First, we consented a conceptual framework and key indicators among experts and stakeholders based on an extensive literature review including national and international NCD surveillance systems. After prioritization of indicators applying a two-step Delphi method, we identified data sources for sustainable surveillance including data from nationwide RKI health surveys as well as external data such as claims or registry data. Lastly, in cooperation with stakeholders we developed first dissemination products.
Results
During concept phase, we identified 40 indicators ranging from risk factors, disease incidence and prevalence to quality of care, mortality and burden of disease. During implementation, suitable data sources and results on temporal trends have been obtained for a large part of the indicators. For dissemination we developed a website with interactive visualization of results supported by an explainer video on YouTube. Additionally, we prepared a printed diabetes report summarizing and interpreting key findings for a broader audience, including health politicians and public health researchers.
Conclusions
We demonstrated the feasibility of the systematic collection and analysis of health data to describe the disease and care situation of diabetes in Germany. The methodology and data sources of indicators can be transferred to further NCDs and shared risk factors are already depicted. Next steps are to close remaining data gaps and to advance dissemination products in collaboration with our stakeholder network tailored to their information needs.
Key messages
Considering available health data, we showed the feasibility of implementing a diabetes surveillance system for Germany providing reliable information on disease dynamics for various stakeholders. The knowledge on methodology and data sources gained establishing a diabetes surveillance system can be extended to other noncommunicable diseases.

Abstract
OBJECTIVE The aim of this study was to investigate the inhibitory role of microRNA-1299 (miR-1299) in prostate cancer, and to explore the possible underlying mechanism. PATIENTS AND METHODS The expression of miR-1299 in 35 PCa tissues and para-carcinoma tissues, as well as PCa cell lines (PC-3) and prostatic epithelial cell line (RWPE-1), was detected by quantitative Real Time-Polymerase Chain Reaction (qRT-PCR). Then, we explored the possible targets of miR-1299 by searching online databases. NIMA-related kinase 2 (NEK2) was identified as a direct target gene of miR-1299. Subsequently, qRT-PCR, Western blot (WB), and luciferase reporter gene assay were used to further verify the correlation between miR-1299 and NEK2. To better characterize the role of miR-1299 and NEK2 in PCa, we conducted functional experiments (MTT, flow cytometry, scratch-wound, and transwell assay) by transfecting PC-3 cells with miR-1299 mimics and si-NEK2 in different groups. RESULTS The expression level of miR-1299 in PCa tissues was significantly lower than that of para-carcinoma tissues. Meanwhile, the expression of miR-1299 in PC-3 cells was also significantly downregulated when compared with RWPE-1 cells. Subsequent qRT-PCR, WB, and luciferase reporter gene assay verified that miR-1299 transcriptionally repressed NEK2 by interacting with the essential binding sequence in 3'-UTR. Also, functional experiments demonstrated that decreased expression of NEK2 resulting from miR-1299 up-regulation could remarkably inhibit the proliferation, invasion, and migration of PCa cells. CONCLUSIONS Our study indicated that miR-1299 was a novel suppressor in PCa through its negative regulation of NEK2. Moreover, our findings revealed that miR-1299/NEK2 axis might be a potential therapeutic target for the treatment of PCa.

Abstract
1. Egg-laying performance reflects the overall reproductive performance of breeding hens. The genetic traits for egg-laying performance have low or medium heritability, and, depending on the period involved, usually ranges from 0.16 to 0.64. Egg-laying in chickens is regulated by a combination of environmental, endocrine and genetic factors. 2. The main endocrine factors that regulate egg-laying are gonadotropin-releasing hormone (GnRH), prolactin (PRL), follicle-stimulating hormone (FSH) and luteinising hormone (LH). 3. In the last three decades, many studies have explored this aspect at a molecular genetic level. Recent studies identified 31 reproductive hormone-based candidate genes that were significantly associated with egg-laying performance. With the development of genome-sequencing technology, 64 new candidate genes and 108 single nucleotide polymorphisms (SNPs) related to egg-laying performance have been found using genome-wide association studies (GWAS), providing novel insights into the molecular genetic mechanisms governing egg production. At the same time, microRNAs that regulate genes responsible for egg-laying in chickens were reviewed. 4. Research on endocrinological and genetic factors affecting egg-laying performance will greatly improve the reproductive performance of chickens and promote the protection, development, and utilisation of poultry. This review summarises studies on the endocrine and genetic factors of egg-laying performance in chickens from 1972 to 2019.

[PMID: 32442842 PMCID: PMC7214341 DOI: 10.1016/j.puhe.2020.05.001] [Citation(s) in RCA: 32] [Impact Index Per Article: 8.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/06/2020] [Revised: 04/18/2020] [Accepted: 05/02/2020] [Indexed: 11/25/2022]
Abstract
OBJECTIVES In December 2019, a novel coronavirus disease (COVID-19) emerged in Wuhan city, China, which has subsequently led to a global pandemic. At the time of writing, COVID-19 in Wuhan appears to be in the final phase and under control. However, many other countries, especially the US, Italy and Spain, are still in the early phases and dealing with increasing cases every day. Therefore, this article aims to summarise and share the experience of controlling the spread of COVID-19 in Wuhan and provide effective suggestions to enable other countries to save lives. STUDY DESIGN Data from the National Health Commission of China are used to investigate the evolution trajectory of COVID-19 in Wuhan and discuss the impacts of the intervention strategies. METHODS A four-stage modified Susceptible-Exposed-Infectious-Removed (SEIR) model is presented. This model considers many influencing factors, including chunyun (the Spring festival), sealing off the city and constructing the Fangcang shelter hospitals. In addition, a novel method is proposed to address the abnormal data on 12-13 February as a result of changing diagnostic criteria. Four different scenarios are considered to capture different intervention measures in practice. The exposed population in Wuhan who moved out before sealing off the city have also been identified, and an analysis on where they had gone was performed using the Baidu Migration Index. RESULTS The results demonstrate that the four-stage model was effective in forecasting the peak, size and duration of COVID-19. We found that the combined intervention measures are the only effective way to control the spread and not a single one of them can be omitted. We estimate that England will be another epicentre owing to its incorrect response at the initial stages of COVID-19. Fortunately, big data technology can help provide early warnings to new areas of the pandemic. CONCLUSIONS The four-stage SEIR model was effective in capturing the evolution trajectory of COVID-19. Based on the model analysis, several effective suggestions are proposed to prevent and control the pandemic for countries that are still in the initial phases.

Abstract
Phenotypic heterogeneity exists within collectively invading packs of tumor cells, suggesting that cellular subtypes cooperate to drive invasion and metastasis. Here, we take a chemical biology approach to probe cell:cell cooperation within the collective invasion pack. These data reveal metabolic heterogeneity within invasive chains, in which leader cells preferentially utilize mitochondrial respiration and trailing follower cells rely on elevated glucose uptake. We define a pyruvate dehydrogenase (PDH) dependency in leader cells that can be therapeutically exploited with the mitochondria-targeting compound alexidine dihydrochloride. In contrast, follower cells highly express glucose transporter 1 (GLUT1), which sustains an elevated level of glucose uptake required to maintain proliferation. Co-targeting of both leader and follower cells with PDH and GLUT1 inhibitors, respectively, inhibits cell growth and collective invasion. Taken together, our work reveals metabolic heterogeneity within the lung cancer collective invasion pack and provides rationale for co-targeting PDH and GLUT1 to inhibit collective invasion. The presence of phenotypic heterogeneity in collectively invading cells suggests cooperation amongst distinct subtypes of cells to promote invasion and metastasis. Here, the authors use chemical biology tools and report metabolic heterogeneity within the lung cancer collective invasion pack.

Abstract
AIM To investigate the characteristics and clinical value of chest computed tomography (CT) images of novel coronavirus pneumonia (NCP). MATERIALS AND METHODS Clinical data and CT images of 80 cases of NCP were collected. The clinical manifestations and laboratory test results of the patients were analysed. The lesions in each lung segment of the patient's chest CT images were characterised. Lesions were scored according to length and diffusivity. RESULTS The main clinical manifestations were fever, dry cough, fatigue, a little white sputum, or diarrhoea. A total of 1,702 scored lesions were found in the first chest CT images of 80 patients. The lesions were located mainly in the subpleural area of the lungs (92.4%). Most of the lesions were ground-glass opacity, and subsequent fusions could increase in range and spread mainly in the subpleural area. Pulmonary consolidation accounted for 44.1% of all of the lesions. Of the 80 cases, 76 patients (95%) had bilateral lung disease, four (5%) patients had unilateral lung disease, and eight (10%) patients had cord shadow. CONCLUSION The chest CT of NCP patients is characterised by the onset of bilateral ground-glass lesions located in the subpleural area of the lung, and progressive lesions that result in consolidation with no migratory lesions. Pleural effusions and mediastinal lymphadenopathy are rare. As patients can have inflammatory changes in the lungs alongside a negative early nucleic acid test, chest CT, in combination with epidemiological and laboratory tests, is a useful examination to evaluate the disease and curative effect.

Abstract
OBJECTIVE To assess the efficacy of metformin in megestrol acetate (MA)-based fertility-sparing treatment for patients with atypical endometrial hyperplasia (AEH) and endometrioid endometrial cancer (EEC). DESIGN A randomised, single-centre, open-label, controlled trial conducted between October 2013 and December 2017. SETTING Shanghai OBGYN Hospital of Fudan University, China. POPULATION A total of 150 patients (18-45 years old) with primary AEH or well-differentiated EEC were randomised into an MA group (n = 74) and an MA plus metformin group (n = 76). METHODS Patients with AEH or EEC were firstly stratified, then randomised to receive MA (160 mg orally, daily) or MA (160 mg orally, daily) plus metformin (500 mg orally, three times a day). MAIN OUTCOMES AND MEASURES The primary efficacy parameter was the cumulate complete response (CR) rate within 16 weeks of treatment (16w-CR rate); the secondary efficacy parameters were 30w-CR rate and adverse events. RESULTS The 16w-CR rate was higher in the metformin plus MA group than in the MA-only group (34.3 versus 20.7%, odds ratio [OR] 2.0, 95% confidence interval [CI] 0.89-4.51, P = 0.09) but the difference was more significant in 102 AEH patients (39.6 versus 20.4%, OR 2.56, 95% CI 1.06-6.21, P = 0.04). This effect of metformin was also significant in non-obese (51.4 versus 24.3%, OR 3.28, 95% CI 1.22-8.84, P = 0.02) and insulin-sensitive (54.8 versus 28.6%, OR 3.04, 95% CI 1.03-8.97, P = 0.04) subgroups of AEH women. No significant result was found in secondary endpoints. CONCLUSION As a fertility-sparing treatment, metformin plus MA was associated with a higher early CR rate compared with MA alone in AEH patients. TWEETABLE ABSTRACT For AEH patients, metformin plus MA might be a better fertility-sparing treatment to achieve a higher early CR rate compared with MA alone.

Abstract
Objective: To investigate the value of bedside pulmonary ultrasound in the diagnosis and treatment of atelectasis in patients after cardiac surgery. Methods: A total of 45 patients developed respiratory failure within 1 week after cardiovascular surgery from April 2017 to April 2018 were enrolled in this study. Among them, 27 were male and 18 were female, mean age was (47±5) years. The postoperative pulmonary ultrasound and chest CT findings were collected, and the consistency, efficacy evaluation, timeliness and safety value of pulmonary ultrasound and chest CT diagnosis were compared. The consistency of the two diagnostic methods was checked based on the Kappa consistency test. Results: A total of 87 foci of atelectasis were diagnosed in 45 patients, including 29 foci of complete atelectasis and 58 foci of incomplete atelectasis. Thoracic CT examination confirmed 44 cases of atelectasis (positive rate 97.8%), and 42 cases (93.3%) were found with atelectasis with ultrasound test. The two methods were consistent in the diagnosis of atelectasis (Kappa value was 0.741, P<0.05). In the evaluation of the atelectasis, the results of the two examination methods were completely consistent, and the pulmonary ultrasound couldcheck the lung recruitment in real time. Ultrasound examination after lung recruitment showed that the total ventilation score of 42 patients decreased significantly when compared with that before treatment ((18.3±3.6) vs (26.6±3.8), t=10.229, P<0.05). There was no significant difference in the safety between the two examination methods. The time the bedside pulmonary ultrasound used was significantly shorter than that in the chest CT. Conclusions: The accuracy of bedside pulmonary ultrasound in assessing atelectasis after cardiovascular surgery is consistent with chest CT, it brings dynamic monitoring of lung status and assessment of lung recruitment by changes in lung ventilation scores. The inspection takes a short time and is worth promoting.

Abstract
BACKGROUND AND PURPOSE This study was to investigate the prevalence and cardiovascular risk factors (CRFs) of asymptomatic intracranial atherosclerotic stenosis (aICAS) amongst middle-aged and older adults living in rural communities in China. METHODS This population-based study included 2019 subjects (aged ≥40 years, 52.3% women) who were free of stroke and living in rural communities in China. From October 2017 to May 2018, data on demographics, CRFs and health conditions were collected through face-to-face interviews, physical examination and laboratory tests. Asymptomatic ICAS was detected through a two-phase procedure: a screening phase with transcranial Doppler ultrasound, followed by a diagnostic phase with magnetic resonance angiography examination. Multivariable logistic regression models were used to analyse CRFs associated with aICAS. RESULTS Of the 2019 participants, aICAS was detected in 153 persons. The overall prevalence of aICAS was 7.6%, and the prevalence of moderate-to-severe aICAS was 5.0%. The multi-adjusted odds ratio (95% confidence interval) of aICAS associated with CRFs was 2.40 (1.56-3.69) for hypertension, 1.91 (1.32-2.76) for high hypersensitive C-reactive protein, 1.68 (1.14-2.49) for diabetes and 1.61 (1.08-2.41) for overweight or obesity. When these four CRFs were aggregated, compared with participants without any of these factors, the multi-adjusted odds ratios (95% confidence interval) of aICAS for persons concurrently having one, two and three or more of these factors were 1.14 (0.52-2.48), 2.91 (1.42-5.99) and 5.51 (2.64-11.50), respectively (P for linear trend <0.001). CONCLUSIONS Asymptomatic ICAS is common amongst rural-dwelling middle-aged and older Chinese people. Hypertension, diabetes, overweight or obesity and high hypersensitive C-reactive protein, especially when coexisting, are strongly associated with aICAS.
