Light is an essential natural factor of fish growth and development. A light regime in indoor aquaculture is critical for sustainable fish production. This research aimed to investigate the effect of light intensity and photoperiod on the growth performance and stress response of Nile tilapia (Oreochromis niloticus), which is an important commercial species, in a recirculating aquaculture system (RAS). Fingerlings with an average weight of 5 ± 0.9 g were randomly assigned to nine 1.5 m3 tanks with 145 fish in each tank, cultured under different light intensities (1000, 2000, and 3000 lx) and photoperiods (12L:12D, 18L:6D, 24L:0D), and fed to apparent satiation twice a day for 160 days. The growth of tilapia subjected to 2000 lx was significantly better than that exposed to 1000 and 3000 lx (P 0.05). Light intensity and photoperiod manipulation did not cause a significant chronic stress response in tilapia. This study demonstrated that light intensity, especially at 2000 lx, and photoperiod manipulation could stimulate the growth of tilapia in the RAS and significantly affect economic profitability. This study also served as an important reference for tilapia indoor aquaculture.

Aims We aimed to validate the predictive value of the ABCD3-I score for short-term and long-term stroke risk after transient ischemic attack (TIA) and to evaluate the influence of symptomatic intracranial artery stenosis (sICAS) on the performance of ABCD3-I. Methods We recruited TIA patients from the Third China National Stroke Registry study. Outcome parameters were stroke events during the 14-day, 3-month, 6-month, and 12-month points. The area under the curve (AUC) was calculated as a measure of predictive ability. A multivariable-adjusted Cox proportional hazards model was used to assess the hazard ratio of risk factors for stroke. Results Among 986 patients, 3.9%, 5.1%, 6.5 %, and 8.2% of participants experienced a stroke event during the 14-day, 3-month, 6-month, and 12-month points post TIA, respectively. The AUCs of ABCD3-I score for the prediction of stroke were 0.786, 0.732, 0.715, and 0.699 at the 14-day, 3-month, 6-month, and 12-month points, respectively. The AUCs were 0.774, 0.690, 0.617, and 0.611 in patients with sICAS, 0.789, 0.748, and 0.758 and 0.734 in those without sICAS. P values of the interaction between ABCD3-I categories and sICAS were 0.0618 for 14-day, 0.0098 for 3-month, 0.0318 for 6-month, and 0.0294 for 12-month. Conclusions ABCD3-I score performed well in predicting short-term risk of a stroke after an index TIA in patients with or without sICAS. However, the predictive power decayed with the prolonged period, and the decayed extent was more pronounced among those with sICAS. The assessment of sICAS is a non-ignorable item when using the ABCD3-I score for long-term stroke risk prediction in patients with TIA.

Iris recognition refers to identifying individuals based on iris patterns, which have been widely used in security systems, such as subway security and access control attendance, because everyone has a unique iris shape. In the study, we propose an OCaNet model for the iris recognition task. First, binarized threshold segmentation is used to locate the pupil and the pupil boundary is obtained; then, the Hough transform is applied to locate the outer edge of the iris; according to the located pupil and iris, the iris area image is obtained through image segmentation; finally, the iris image is normalized to adjust each original image to the same size and corresponding position, so as to eliminate the influence of translation, scaling, and rotation on iris recognition. Second, the normalized iris images are both input into the octave convolution module and attention module. The octave convolution module is used to extract the shape and contour features of the iris by decomposing the feature map into high and low frequencies. The attention module is applied to extract the color and texture characteristics of the iris. Finally, the two feature maps are concatenated and produce a distribution of output classes. Experimental results show that the proposed OCaNet model is significantly more accurate.

Background and Purpose: Quantitative electroencephalogram (QEEG) parameters have been previously utilized in prognosis following acute ischemic stroke (AIS). However, the use and interpretation of QEEG parameters remain scarce following endovascular treatment (EVT) of AIS.Methods: AIS patients were prospectively enrolled following EVT, and 24-hour EEG monitoring was conducted. Global delta/alpha ratio (DAR), (delta + theta)/(alpha + beta) ratio (DTABR), and relative band power were analyzed. Primary outcome was a poor outcome (modified Rankin Scale ≥4 at 90-day follow-up). Multivariate logistic regression and diagnostic analyses were performed.Results: Poor outcome was seen in 35.5% (11/31) of enrolled patients. Multivariable logistic regression identified that higher DAR (OR 1.10, 95% CI 1.02-1.18, p = 0.02) and higher DTABR (OR 1.13, 95% CI 1.01-1.27, p = 0.02) were associated with poor outcome. DAR ≥14.3 demonstrated high sensitivity (90.9%), specificity (90.0%) and accuracy (90.3%) for poor outcome.Conclusions: Early evidence of elevated DAR and DTABR on quantitative EEG was associated with poor outcome at 90 days following EVT for AIS.

Non-alcoholic steatohepatitis is frequently associated with diabetes and may cause progressive liver disease. Current treatment options are limited. Here we report on a prospective, randomised, double-blind, placebo-controlled trial of two doses of HTD1801 (berberine ursodeoxycholate, an ionic salt of berberine and ursodeoxycholic acid), versus placebo that was conducted in 100 subjects with fatty liver disease and diabetes (NCT03656744). Treatment was for 18 weeks with a primary endpoint of reduction in liver fat content measured by magnetic resonance imaging proton density fat fraction. Key secondary endpoints included improvement in glycemic control, liver-associated enzymes and safety. The pre-specified primary endpoint was met. Thus, subjects receiving 1000 mg twice a day of berberine ursodeoxycholate had significantly greater reduction in liver fat content than in placebo recipients (mean absolute decrease −4.8% vs. −2.0% (p = 0.011). Compared to placebo, subjects receiving this dose also experienced significant improvement in glycemic control as well as reductions in liver-associated enzymes and significant weight loss. Diarrhea and abdominal discomfort were the most frequently reported adverse events. We conclude that berberine ursodeoxycholate has a broad spectrum of metabolic activity in patients with presumed NASH and diabetes. It is relatively well tolerated and merits further development as a treatment for NASH with diabetes., Berberine ursodeoxycholate has been studied for its serum lipid and lipoprotein lowering effects. Here the authors report an 18-week phase 2, randomised, double-blind, placebo-controlled clinical trial that tested the effect of berberine ursodeoxycholate in patients with fatty liver disease and diabetes, and showed that the group taking the higher dose of the drug had reduced liver fat content.

Background and Purpose: It is still unclear whether the residual cholesterol and inflammatory risk in the acute phase is associated with prognosis of stroke. We aimed to investigate the proportion and relative contribution of residual cholesterol and inflammatory risk, determined by baseline low-density lipoprotein cholesterol (LDL-C) and high-sensitivity C-reactive protein (hsCRP) levels, to the risk of recurrent stroke and poor functional outcome at 1 year. Methods: In this prospective multicenter cohort study, 10 499 consecutive acute ischemic stroke and transient ischemic attack patients with levels of LDL-C and hsCRP were enrolled. Patients were divided into 4 groups: residual cholesterol risk only (LDL-C ≥2.6 mmol/L and hsCRP Results: The relative proportions of patients with RIR only, residual cholesterol risk only, both risk, and neither were 21.3%, 23.7%, 14.4%, and 40.6%, respectively. RIR only was independently associated with recurrent stroke (adjusted hazard ratio, 1.18 [95% CI, 1.00–1.40]; P =0.05). The association was slightly attenuated after further adjusting for usage of antiplatelet agent and statin during 1-year follow-up in addition to the traditional risk factors (hazard ratio, 1.31 [95% CI, 0.99–1.76]; P =0.07). When applying the LDL-C cutoff value of 1.8 mmol/L in the sensitivity analyses, such association in large-artery atherosclerosis subtype was more significant (adjusted hazard ratio, 1.69 [95% CI, 1.06–2.67]; P =0.03). Patients with RIR only also had increased risk of poor functional outcome (adjusted odds ratio, 1.43 [95% CI, 1.24–1.64]; P Conclusions: In the patients with acute ischemic stroke or transient ischemic attack, RIR only could be predictive for recurrent stroke, especially for those with large-artery atherosclerosis, and poor functional outcome.

PurposeEmployee health is a major challenge for enterprises. Fostering a healthy work environment and promoting employee engagement are key to addressing this challenge. Health-promoting leadership and employee health are the driving forces of corporate development; at the same time, employability is the core element of employee relations. Based on self-determination theory, this study aims to explore the effects of health-promoting leadership and employee health on employee engagement in light of employee employability.Design/methodology/approachThe data of this study encompass 723 valid questionnaires from employees of MSME in China. This study focuses on health-promoting leadership and employee health, engagement relationship and the above relationship moderating by employability.FindingsHealth-promoting leadership plays a key role in the workplace, results show that health-promoting leadership has a positive impact on employee health and employee engagement, while employee health did not have a positive effect on employee engagement. Employability negatively moderated the relationship between employee health and employee engagement.Research limitations/implicationsThis study is based on cross-sectional survey data collected at the COVID-19 pandemic. The pandemic rapidly and continuously changed the organizational responses to employee health. Future studies could utilize longitudinal methods or focus on measurement instruments of the culture of health, to create additional insights about health promoting.Originality/valueThis study adds important knowledge regarding health-promoting leadership and employee health in Chinese MSMEs, an area for which limited research exists. The findings provide insights and knowledge about health-promoting leadership how to affect employee health and to improve engagement outcomes. The findings also identify the moderating role of employability.

Background and Purpose: Existing studies on the association between hemoglobin values and stroke outcomes mostly focus on the lower side and mortality, often the only and primary endpoint. The current study was conducted to assess the association between hemoglobin concentration and a variety of poor stroke outcomes in patients with acute ischemic stroke. Methods: We studied 8,321 patients enrolled in the China National Stroke Registry (CNSR) between 2007 and 2008. Patients were divided into 7 groups, and a logistic regression model was used to evaluate the association. Endpoints of interest included 1-year all-cause mortality, stroke recurrence, combined endpoint, and stroke disability. Stroke disability was defined as a modified Rankin Scale of 2–6. Results: Patients with low and high hemoglobin values (≤11.6 g/dL and >16.1 g/dL) had higher proportion of poststroke adverse events than those in other groups. As compared with the fourth group of hemoglobin values of 13.5–14.2 g/dL, the adjusted odds ratios (ORs) with 95% confidence interval (CI) of low hemoglobin values (≤11.6 g/dL) were 2.25 (1.72–2.93) for all-cause mortality, 1.30 (1.04–1.61) for stroke recurrence, 1.63 (1.33–2.01) for combined endpoint, and 1.37 (1.12–1.67) for stroke disability, respectively. And, the ORs of high hemoglobin values (>16.1 g/dL) for adverse stroke outcomes were 1.72 (1.25–2.37), 1.43 (1.13–1.82), 1.43 (1.13–1.81), and 1.31 (1.06–1.63), respectively. Stratified analysis showed significant interactions between sex and categories of hemoglobin values for all-cause mortality (p = 0.05), stroke recurrence (p = 0.03), and combined endpoint (p = 0.01) but not for stroke disability (p = 0.24). Conclusions: Our study found both low and high hemoglobin values were associated with adverse stroke outcomes including all-cause mortality, stroke recurrence, combined endpoint, and stroke disability, which showed a U-shaped association. And, significant interactions between sex and hemoglobin concentration on all-cause mortality and stroke recurrence were also identified.

Objectives: The impact of COVID-19 pandemic on endovascular therapy (EVT) for acute ischemic stroke in China is unknown. This study was aimed to verify the volume change of EVT for acute ischemic stroke affected by COVID-19 and its potential factors.Methods: This cross-sectional study was conducted via an online questionnaire survey in China. The questionnaire was mainly composed of descriptive information, volume change of EVT for acute ischemic stroke, and the protection status of medical staff.Results: A total of 103 stroke physicians in 28 provinces across China completed the survey questionnaire. A volume decline in EVT for acute stroke occurred in 93 (90.3%) hospitals after lockdown (23 January 2020). Nearly half of the hospitals (51/103, 49.5%) experienced a volume decline of EVT case more than 50% and 14 (13.6%) hospitals completely ceased offering EVT. Hospitals with decline >50% of EVT case had higher proportion of hospitals with a designated area for COVID-19 screening in the emergency room (44/51, 86.3% vs 34/52, 65.4%, p= 0.01) and medical staff in quarantine (19/51, 37.3% vs 7/52, 13.5%, p

Although there are reports that artificial sweeteners (AS) are safe, the relationship between artificial sweeteners and cancer remains controversial. The purpose of the study is to evaluate whether the consumption of artificial sweeteners is associated with the risk of cancers. We conducted a comprehensive search of multiple databases, including MEDLINE, EMBASE, Web of Science, and Cochrane Library. We found all the literature that studied the relationship between artificial sweeteners and cancer. Ten case–control studies were included in the meta‐analysis. Our findings indicated that the consumption of artificial sweeteners was not associated with an increase in cancer when all types of cancers are analyzed comprehensively (OR 0.91, 95% CI 0.75–1.11). Interestingly, the use of artificial sweeteners is inversely related to urinary system cancer risk when analyzing women individually (OR 0.76, 95% CI 0.60–0.97). Our meta‐analysis found that these is no correlation between artificial sweeteners and occurrence of cancer except urinary system cancer in women. Considering some limitations found in this study, additional data from large clinical trials are needed., Although there are reports that artificial sweeteners (AS) are safe, the relationship between artificial sweeteners and cancer remains controversial. The purpose of the study is to evaluate whether the consumption of artificial sweeteners is associated with the risk of cancers.

Purpose: Patients with HER2-positive (HER2+) metastatic breast cancer (MBC) have poor prognoses. Pyrotinib has shown promising antitumor activity in MBC to improve progression-free survival (PFS). However, findings based on real-world data to analyze whether pyrotinib affects overall survival (OS) remain scarce. Experimental Design: This real-world study is an exploratory analysis of brain metastasis (BM) and the final update of our preceding study of 168 patients with HER2+ MBC. PFS, OS, tumor mutation burden (TMB), clinical benefit rate (CBR), and overall response rate (ORR) were analyzed. Results: Pyrotinib treatment led to a median PFS time of 8.00 months and a median OS of 19.07 months in the 168 participants. High TMB was associated with poor OS (P = 0.0072) and PFS (P = 0.0028). In the 39 patients with BM, the median PFS and OS were 8.67 and 13.93 months, respectively. The surgery/radiation (S/R) group of patients with BM had prolonged survival (PFS: 9.97 vs. 7.73 months P = 0.19; OS: 20.67 vs. 12.43 months P = 0.021) compared with the no surgery/no radiation group (NS/NR). The CBR was 58.6% (S/R) vs. 41.4% (NS/NR), while the ORR was 24.1% (S/R) vs. 31.0% (NS/NR). Conclusions: Pyrotinib shows promise as a novel pan-HER2 tyrosine kinase inhibitor (TKI) for the treatment of BM and should be evaluated further. Surgical or radiotherapy in combination with pyrotinib was found to statistically improve OS in our cohort. TMB could be an exploratory biomarker for predicting PFS and OS, but its clinical application still needs further verification.

Objective The aim of this study was to find out the relationship between serum biomarkers and cerebral collateral status in acute ischemic stroke with cerebral large artery atherosclerosis. Methods We enrolled patients with ischemic stroke due to large artery atherosclerosis within 7 days of symptom onset, age 18-80 years, from August 2016 to December 2017. Twelve biomarkers representing different pathophysiological mechanisms were tested after admission. Whole-brain perfusion combined with multiphase computed tomography angiography was performed to assess cerebral collateral structure and function. Results Fifty-two patients completed the test of candidate biomarkers and recruited in this study. The mean age was 55.0 (11.1) years, 42 (80.8%) patients were male, 20 (38.5%) had poor collateral, 36 (69.2%) patients had anterior circulation stenosis or occlusion. Compared with poor collateral group, the level of MMP-9 (135,475.00 pg/ml vs. 103,612.00 pg/ml, p = 0.040) and PGF (5.75 pg/ml vs. 3.46 pg/ml, p = 0.046) was significantly higher in good collateral group. The adjusted OR (95%CI) of MMP-9 and PGF were 5.533 (1.10-27.74, p = 0.038), 7.73 (1.41-42.39, p = 0.018), respectively. sTie-2 level had a positive correlation with proportion of Tmax 4-6 (r = 0.302, p = 0.033) and HMW-KGN had negative correlation with proportion of Tmax 6-8 (r = -0.338, p = 0.02). After adjustment, the correlation of sTie-2 level and proportion of Tmax 4-6 was statistically significant (p = 0.003), and correlation of HMW-KGN and Tmax6-8 was not statistically significant (p = 0.056). Discussion Serum PGF and MMP-9 levels may correlate with collateral status based on MP-CTA in acute ischemic stroke patients with cerebral large artery atherosclerosis. Higher PGF and MMP-9 concentration associated with good collateral status.

BACKGROUND The increasing incidence of cancer among young adults (18-40 years old) is of concern in China. OBJECTIVES This study aims to examine the influence of cancer information-seeking behaviours (CISB) on young adults' worries about cancer and participation in screening. METHODS This study analysed data from two probability sample surveys conducted in 2012 and 2017 in China. The questions in the questionnaire remained the same for better comparison. The sample size was 1212 in the 2012 survey, and 2178 in the 2017 survey. RESULTS From 2012 to 2017, among young adults, there was a decline in cancer information seeking, diversity of cancer information sought and cancer worry, while an improvement in cancer information-seeking experience was found. Also, CISB had significant associations with cancer worry and health screening over the 5 years. DISCUSSION The level of young adults' cancer information seeking remains low in China, and this group is not fully aware of their potential risks of getting cancer. CONCLUSION Although young adults find the experience of looking for cancer information easier in 2017, health campaigns may be necessary to encourage young adults to find out more about their cancer risks, and to participate more in health screening.

Background and Purpose: Whether imaging parameters would independently predict stroke recurrence in low-risk minor ischemic stroke (MIS) or transient ischemic attack (TIA) according to traditional score system (such as ABCD 2 score, which was termed on the basis of the initials of the five factors: age, blood pressure, clinical features, duration, diabetes) remains unclear. We sought to evaluate the association between imaging parameters and 1-year stroke recurrence in patients with TIA or MIS in different risk stratum stratified by ABCD 2 score. Methods: We included patients with TIA and MIS (National Institutes of Health Stroke Scale score ≤3) with complete baseline vessel and brain imaging data from the Third China National Stroke Registry III. Patients were categorized into different risk groups based on ABCD 2 score (low risk, 0–3; moderate risk, 4–5; and high risk, 6–7). The primary outcome was stroke recurrence within 1 year. Multivariable Cox proportional-hazards regression models were used to assess whether imaging parameters (large artery stenosis, infarction number) were independently associated with stroke recurrence. Results: Of the 7140 patients included, 584 patients experienced stroke recurrence within 1 year. According to the ABCD 2 score, large artery stenosis was associated with higher stroke recurrence in both low-risk (adjusted hazard ratio, 1.746 [95% CI, 1.200–2.540]) and moderate-risk group (adjusted hazard ratio, 1.326 [95% CI, 1.042–1.687]) but not in the high-risk group ( P >0.05). Patients with multiple acute infarctions or single acute infarction had a higher risk of recurrent stroke than those with no infarction in both low- and moderate-risk groups, but not in the high-risk group. Conclusions: Large artery stenosis and infarction number were independent predictors of 1-year stroke recurrence in low-moderate risk but not in high-risk patients with TIA or MIS stratified by ABCD 2 score. This finding emphasizes the importance of early brain and vascular imaging evaluation for risk stratification in patients with TIA or MIS.

Colorectal cancer (CRC) is a frequently occurring digestive system cancer and postoperative tumor metastasis and recurrence are the main reasons for the failure of CRC treatment. The aim of this study was to identifying and validating key genes associated with metastatic recurrence of CRC. RNA expression of three datasets (GSE17538, GSE32323, and GSE29623) was used for biomarker discovery. We identified integrin‐binding sialoprotein (IBSP) as a candidate biomarker which was validated in three clinical cohorts (GSE41258, GSE21510, and GSE39582) and our clinical specimens. The results suggested that IBSP expression significantly increased at mRNA and protein levels among CRC cases, which was associated with metastatic recurrence, metastasis, high risk of recurrence, and poor survival in CRC. Consistent results were obtained in CRC cells. The relative level of serum IBSP evidently increased among CRC patients relative to normal controls, and downregulated after operation. As suggested by gene set enrichment analysis (GSEA), the IBSP level was associated with cell‐matrix adhesion in CRC. Functional experiments in vitro showed that IBSP promoted the growth and aggressiveness of CRC, and the potential mechanism by which IBSP promoted carcinogenesis of CRC was the abnormal activation of Fyn/β‐catenin signaling pathway. To sum up, findings in the present work indicate that IBSP can serve as the candidate biomarker for the diagnosis, treatment, and prognosis of CRC., In this study, we identified and validated IBSP as a key gene associated with metastatic recurrence of CRC which might serve as the candidate biomarker for the diagnosis, treatment, and prognosis of CRC. Our results suggested that IBSP expression significantly increased at mRNA and protein levels among CRC cases, which was associated with metastatic recurrence, metastasis, high risk of recurrence, and poor survival in CRC. Functional experiments in vitro showed that IBSP promoted the growth and aggressiveness of CRC, and the potential mechanism by which IBSP promoted carcinogenesis of CRC was the abnormal activation of Fyn/β‐catenin signaling pathway.

Background and Purpose: Intraluminal thrombus (ILT) is an emerging imaging marker in acute ischemic stroke. We aimed to investigate the association of ILT with outcomes of acute large vessel occlusion (LVO) patients receiving endovascular treatment. Methods: Acute LVO stroke patients who underwent endovascular treatment within 24 hours, in a prospective, nationwide registry were enrolled. Pretreatment digital subtraction angiography was reviewed for the presence of ILT. The primary outcome was 90-day functional dependence (modified Rankin Scale scores, 3–6). Secondary outcomes included 24-hour LVO, 90-day death, and symptomatic intracranial hemorrhage. Results: Among 711 patients enrolled, 75 (10.5%) with ILT were less likely to have 90-day functional dependence compared with those without ILT (adjusted odds ratio, 0.53 [95% CI, 0.31–0.90]; P =0.021). The same trend was found among those with successful reperfusion (modified Thrombolysis in Cerebral Infarction 2b–3; P =0.008) but not in those without successful reperfusion ( P =0.107). Presence of ILT was also independently associated with a lower rate of 24-hour LVO (adjusted odds ratio 0.34 [95% CI, 0.13–0.89]; P =0.028). However, those with or without ILT had similar risks of symptomatic intracranial hemorrhage and 90-day death. Conclusions: Among acute LVO patients receiving endovascular treatment, pretreatment ILT-positive patients may have a better 90-day functional outcome (versus ILT-negative) but similar risk of death and symptomatic intracranial hemorrhage. The possibly favorable effect of ILT patients remained in those with successful reperfusion. Registration: URL: http://www.chictr.org.cn ; Unique identifier: ChiCTR1900022154.

Background and purposeCurrent randomised controlled trials (RCTs) showed an uncertain benefit of haemostatic therapy on preventing haematoma expansion and improving the outcome in patients with intracerebral haemorrhage (ICH). This meta-analysis aims to systematically evaluate the effect of haemostatic agents on the prevention of haemorrhage growth in patients with high-risk spontaneous ICH predicted by CT signs in RCTs.MethodsA comprehensive search of PubMed, EMBASE and Cochrane library from 1 January 2005 to 30 June 2021 was conducted. RCTs that compared haemostatic agents with placebo for the treatment of spontaneous patients with ICH with high-risk haemorrhage growth were included. The primary endpoint was haematoma expansion at 24 hours. Other major endpoints of interest included 90-day functional outcome and mortality.ResultsThe meta-analysis included four RCTs that randomised 2666 patients with ICH with high-risk haemorrhage growth. Haemostatic therapy reduced the rate of haematoma expansion at a marginally statistically significant level when compared with placebo (OR 0.84; 95% CI 0.70 to 1.00; p=0.051). Subgroup analysis for patients with black hole sign on CT revealed a significant reduction of haematoma expansion with haemostatic therapy (OR 0.61; 95% CI 0.39 to 0.94; p=0.03). However, both the primary analysis and subgroup analyses showed that haemostatic therapy could not reduce the rate of poor functional outcome (modified Rankin Scale >3) or death.ConclusionsHaemostatic therapy showed a marginally significant benefit in reducing early haematoma expansion in patients with high-risk spontaneous ICH predicted by markers on CT scan. However, no significant improvement in functional outcome or reduction of mortality was observed.

Due to the lack of a suitable gene signature, it is difficult to assess the hypoxic exposure of HCC tissues. The clinical value of assessing hypoxia in HCC is short of tissue‐level evidence. We tried to establish a robust and HCC‐suitable hypoxia signature using microarray analysis and a robust rank aggregation algorithm. Based on the hypoxia signature, we obtained a hypoxia‐associated HCC subtypes system using unsupervised hierarchical clustering and a hypoxia score system was provided using gene set variation analysis. A novel signature containing 21 stable hypoxia‐related genes was constructed to effectively indicate the exposure of hypoxia in HCC tissues. The signature was validated by qRT‐PCR and compared with other published hypoxia signatures in multiple large‐size HCC cohorts. The subtype of HCC derived from this signature had different prognosis and other clinical characteristics. The hypoxia score obtained from the signature could be used to indicate clinical characteristics and predict prognoses of HCC patients. Moreover, we reveal a landscape of immune microenvironments in patients with different hypoxia score. In conclusion, we identified a novel HCC‐suitable 21‐gene hypoxia signature that could be used to estimate the hypoxia exposure in HCC tissues and indicated prognosis and a series of important clinical features in HCCs. It may enable the development of personalized counselling or treatment strategies for HCC patients with different levels of hypoxia exposure.

We aim to evaluate the risk of stroke recurrence among non-diabetes mellitus (non-DM), previously diagnosed diabetes mellitus (PDDM), newly diagnosed diabetes mellitus-related hyperglycemia (NDDM-RH) and stress hyperglycemia after minor stroke or TIA. Totally, 3026 patients with baseline fasting glucose and glycated albumin from the CHANCE trial (Clopidogrel in High-Risk Patients with Acute Nondisabling Cerebrovascular Events) were included. Patients were classified as non-DM, PDDM, NDDM-RH and stress hyperglycemia according to the status of glucose metabolism. The primary outcome was stroke recurrence during 90-day follow up. Cox regression was performed to estimate the relationship between the status of glucose metabolism and risk of 90-day stroke recurrence. Compared with PDDM, NDDM-RH had a similar risk of 90-day stroke recurrence (hazard ratios [HR]1.39, 95% confidence intervals [CI] 0.94-2.04), while stress hyperglycemia had approximately a 5.3-fold increased risk of 90-day stroke recurrence after adjusted for confounding covariates (HR 5.32, 95% CI 3.43-8.26). Parallel results were found for 90-day recurrent ischemic stroke and composite events. Compared with PDDM in minor stroke or TIA, a parallel risk of 90-day stroke recurrence were observed for NDDM-RH, while stress hyperglycemia might relate to higher risk of 90-day stroke recurrence.

This study investigates the contextual and relational characteristics that underlie people’s information and communication technology (ICT) use and the implications for their well-being. We contextualize this investigation according to migrants, because they are faced with disruptions to their personal networks in the migration process that may attenuate the availability of social support and negatively affect their mental health. Migrants tend to be proficient in using mobile ICT to connect with different social ties to fulfill their needs, which potentially makes a difference to their psychological well-being. Through a survey of 504 internal migrant workers in China, we examined the social network factors that underlie multiple mobile ICT use and the attendant influences on social support and psychological well-being. Redressing the overemphasis on the importance of strong ties in extant literature, this study highlights the salience of mobile media multiplexity (i.e., the use of multiple mobile communication channels for social interactions) in weak tie communication and the greater contribution of weak ties toward social support and psychological well-being than strong ties. Our findings suggest that mobile-mediated communicative relationships with newer and more distanced social connections outside their immediate circles enhance the well-being of migrants. We contend that media multiplexity vis-à-vis weak ties underscores the reconfiguration of migrants’ communicative relationships following the separation from original ties and facilitates rewarding interactions with new ties.

We evaluated the AF-related risk factors and its association with pericardial fat in Chinese patients.Methods: Patients referred for coronary computed tomography angiography (CCTA) in Shanghai East Hospital during 2012 to 2014 (n=2042, 43.8% women, mean age 65.0 years) had AF and cardiovascular risk assessment. Pericardial fat depots were measured from CT and the association of EFV with non-valvular AF risk factors was evaluated by multivariate logistic regression models.Results: AF was present in 8.5% of patients with 11.6% of AF patients having rheumatic heart disease (RHD) and 8.7% having other valvular diseases. With increasing age, the proportion of RHD-related AF decreased and the risk factors for non-valvular AF increased. There was a significantly higher proportion of risk factors for non-valvular AF in men than in women (p=0.008), but RHD-related AF was more prevalent in women than men (p=0.013). The patients with non-valvular AF had significantly higher BMI and EFV with more pronounced elevation of EFV (p< 0.001). Multivariate logistic regression showed a significant association of EFV with AF after adjustment for BMI and clinical risk factors, and the highest EFV quartile was associated with AF independent of left atrial size and obstructive coronary artery disease.Conclusion: The association of EFV with non-valvular AF in Chinese patients was independent of generalized adiposity and clinical risk factors especially in highest EFV quartile. These findings support the growing appreciation of the association of EFV with AF.Keywords: atrial fibrillation, epicardial fat, pericardial fat, obesity, body mass index, computed tomography, echocardiography

Flexible pressure sensors (FPSs) are widely demanded for accurate pressure sensing on complex surfaces. FPSs using metal nanoparticles (NPs) as the sensing material have high conductivity and good mechanical properties, but poor gauge factor as a trade-off. In this work, a novel design of the AgNP-based FPS is proposed and testified with the help of the electrohydrodynamics-printing technology, so that the gauge factor can be improved from 8 to 286.8, resulting from the localized micro-zone piezoresistance effect. The working principle of the piezoresistive characteristic is discussed, and two methods to further improve and adjust the gauge factor are proposed and experimentally demonstrated.

Background: Metastatic breast cancer (MBC) has poor prognosis, and the 5 yr-OS is less than 20%. Maintaining treatment post the chemotherapy could improve the OS and the life quality. However, we lack clinical consensus for the maintaining treatment. In this study, we aim to investigate the treatment outcome of capecitabine maintaining treatment. Methods: The study recruited 669 consecutive MBC patients who received chemotherapy from January 2016 through August 2019. 256 patients received capecitabine maintaining treatment after chemotherapy, including 163 patients with maintaining treatment after the first-line chemotherapy and 67 patients with maintaining treatment after the second-line chemotherapy. 413 patients did not receive capecitabine maintaining treatment after capecitabine-based chemotherapy. Kaplan-Meier curves were plotted and COX proportional hazards models with candidate risk factor analyses stratified by chemotherapy lines and maintaining treatment were assessed the impact of each candidate on progression-free survival (PFS). Circulating tumor DNA (ctDNA) analysis was performed to screen genetic aberrations that might lead to maintaining treatment response. Results: Capecitabine maintaining treatment group showed a significant improvement in PFS compared with non-maintaining group [hazard ratio = 0.53 (95% confidence interval = 0.41-0.68); log-rank test p Citation Format: Quchang Ouyang, Zhe-Yu Hu, Xiaohong Yang, Liping Liu, Jing Li, Huawu Xiao, Jianxiang Gao, Jun Lu, Hui Wu, Ning Xie, Xuming Hu, Can Tian, Zhengrong Shui, Min Cao.

Photodynamic therapy (PDT) has been extensively investigated for decades for tumor treatment because of its non-invasiveness, spatiotemporal selectivity, lower side-effects, and immune activation ability. It can be a promising treatment modality in several medical fields, including oncology, immunology, urology, dermatology, ophthalmology, cardiology, pneumology, and dentistry. Nevertheless, the clinical application of PDT is largely restricted by the drawbacks of traditional photosensitizers, limited tissue penetrability of light, inefficient induction of tumor cell death, tumor resistance to the therapy, and the severe pain induced by the therapy. Recently, various photosensitizer formulations and therapy strategies have been developed to overcome these barriers. Significantly, the introduction of nanomaterials in PDT, as carriers or photosensitizers, may overcome the drawbacks of traditional photosensitizers. Based on this, nanocomposites excited by various light sources are applied in the PDT of deep-seated tumors. Modulation of cell death pathways with co-delivered reagents promotes PDT induced tumor cell death. Relief of tumor resistance to PDT with combined therapy strategies further promotes tumor inhibition. Also, the optimization of photosensitizer formulations and therapy procedures reduces pain in PDT. Here, a systematic summary of recent advances in the fabrication of photosensitizers and the design of therapy strategies to overcome barriers in PDT is presented. Several aspects important for the clinical application of PDT in cancer treatment are also discussed.

This paper deals with the problem of large number of parameters and complex calculation in video abstract generation of Fully Connected Network and Convolutional Neural Network. At the same time, the training and testing of such model need a lot of time and computer resources. We came up with a deep learning network parameter compression method based on Singular Value Decomposition(SVD) and Trucker Decomposition (TD) is proposed to generate the video summaries. The experiment was compared with other methods on TVSum and SumMe dataset, and the F1 value was 55.3% in TVSum dataset and 46.8% in SumMe dataset. At the same time, the degree of test time shortening under the same data volume is taken as the evaluation basis. The experimental results show that the proposed method achieves 1.04 times of acceleration in the SVD forward calculation, and 1.29 times of acceleration in the TD forward calculation. In a conclusion, the neural network model based on low-rank decomposition can effectively save computer resources and the time consumed by running programs.

Studies on antiplatelet effect of ticagrelor/aspirin and clopidogrel/aspirin in patients with acute minor stroke and transient ischemic attack (TIA) stratified by CYP2C19 metabolizer status is limited. We gained data from the Platelet Reactivity In Non-disabling Cerebrovascular Events study. Platelet reactivity was tested at baseline, 2 hours, 24 hours, 7 days and 90 days after initial dose, including high on-treatment platelet reactivity (HOPR), which was defined as P2Y12 reaction unit >208, and percentage inhibition of platelet aggregation (IPA). A total of 365 patients were included. There were 199 (54.5%) individuals classified as carriers of CYP2C19 loss-of-function alleles. For carriers and non-carriers, the proportions of HOPR were significantly lower in those with ticagrelor/aspirin compared with those with clopidogrel/aspirin at 2 hours, 24 hours, 7 days, respectively (all p

Background Reduction in elevated serum cholesterol concentrations is important in the management of individuals at risk of atherosclerotic cardiovascular disease (ASCVD), such as myocardial infarction and thrombotic stroke. Although HMGCoA reductase inhibitors (“statins”) are frequently used for this purpose, a significant proportion of patients remain at increased residual risk of ASCVD as they do not adequately address some of the associated co-morbidities such as diabetes and fatty liver disease. Methods A double-blind, randomized, placebo-controlled, dose ranging study was carried out that compared three doses of berberine ursodeoxycholate (BUDCA) to placebo in a cohort of subjects with a history of hypercholesterolemia and serum LDL cholesterol levels above 2.59 mmol/L (> 99.9 mg/dL). BUDCA was administered in two divided doses each day for 28 days. The primary endpoints of the study were safety and tolerability of this new compound, as well as its effect in lowering serum lipid and lipoprotein concentrations. Results A total of 50 subjects were enrolled into three dose cohorts in this study. BUDCA was generally well tolerated, even at doses of 2000 mg per day (the highest dose group); there were no significant adverse effects reported and this highest dose was associated with significant reductions in LDL cholesterol. By day 28 and with the highest dose of BUDCA, there were significant reductions in the serum concentrations of total cholesterol by 8.2% (P = 0.0004) and LDL cholesterol by 10.4% (P = 0.0006), but no significant changes in triglyceride and HDL cholesterol concentrations. Conclusions BUDCA is a new single molecular entity that has a significant but modest effect in safely lowering serum LDL-cholesterol concentrations in individuals with a history of hypercholesterolemia. It has a potential use for treating hypercholesterolemia in individuals who cannot take statins, and possibly as adjunctive to other agents, such as ezetimibe or bempedoic acid. Trial registration The study was registered on Clinicaltrials.gov (NCT03381287).

BackgroundMedical complications strongly affected the mortality of patients with stroke. However, only limited research has studied the effect of in-hospital medical complications on the mortality of patients with spontaneous intracerebral haemorrhage (ICH) globally. Using the China National Stroke Registry, the effect was prospectively and systematically investigated in patients with spontaneous ICH during their hospitalisation, at 3, 6 and 12 months after disease onset.MethodsThis study collected data on patients over 18 years old with spontaneous ICH from 132 Chinese clinical centres across 32 provinces and four municipalities (Hong Kong included), from September 2007 to August 2008. Data on patient complications, death and other information were acquired through paper-based registry forms. Using multivariable logistic regression, the association of medical complications with stroke outcomes was evaluated.ResultsOf 3255 patients with spontaneous ICH, 878 (26.97%) had in-hospital medical complications. In-hospital medical complications were independent risk factors for death during the hospitalisation (adjusted OR 4.41, 95% CI 3.18 to 6.12), at 3 months (adjusted OR 2.18, 95% CI 1.70 to 2.80), 6 months (adjusted OR 1.84, 95% CI 1.45 to 2.34) and 12 months (adjusted OR 1.59, 95% CI 1.26 to 2.01) after spontaneous ICH.ConclusionThe results revealed that the short-term and long-term mortality of patients with spontaneous ICH in China was significantly associated with their in-hospital medical complications.

BackgroundWhether to treat minor stroke with intravenous tissue plasminogen activator (t-PA) treatment or antiplatelet therapy is a dilemma. Our study aimed to explore whether intravenous t-PA treatment, dual antiplatelet therapy (DAPT) and aspirin have different efficacies on outcomes in patients with minor stroke.MethodsA post hoc analysis of patients with acute minor stroke treated with intravenous t-PA within 4.5 hours from a nationwide multicentric electronic medical record and patients with acute minor stroke treated with DAPT and aspirin from the Clopidogrel with Aspirin in Acute Minor Stroke or Transient Ischemic Attack Database. Minor stroke was defined by a score of 0–3 on the National Institutes of Health Stroke Scale at randomisation. Favourable functional outcome (defined as modified Rankin Scale (mRS) score of 0–1 or 0–2 at 3 months).ResultsCompared with those treated with intravenous t-PA, no significant association with 3-month favourable functional outcome (defined as mRS score of 0–1) was found neither in patients treated with aspirin (87.8% vs 89.4%; OR, 0.83; 95% CI, 0.46 to 1.50; p=0.53) nor those treated with DAPT (87.4% vs 89.4%; OR, 0.84; 95% CI, 0.46 to 1.52; p=0.56). Similar results were observed for the favourable functional outcome defined as mRS score of 0–2 at 3 months.ConclusionsIn our study, no significant advantage of intravenous t-PA over DAPT or aspirin was found. Due to insufficient sample size, our study is probably unable to draw such a conclusion that that intravenous t-PA was superior or non-superior to DAPT.

In this study, we tested the effect of ticagrelor versus clopidogrel on platelet reactivity in patients with minor stroke or transient ischemic attack (TIA). A pre-specified subgroup analysis of a randomized controlled trial was conducted. Platelet reactivity was assessed by thrombelastography (TEG) platelet mapping. Patients were divided into carriers and non-carriers according to the carrier status of CYP2C19 loss-of-function (LOF) alleles. The primary outcome was the proportion of patients with high on-treatment platelet reactivity (HOPR) (defined as maximum amplitude induced by adenosine diphosphate > 47mm) at 90±7 days. Clinical outcomes within 90±7 days were followed up. Among 339 patients, 170 were randomized to ticagrelor/aspirin and 169 to clopidogrel/aspirin. Compared with clopidogrel/aspirin, the proportion of HOPR at 90±7 days in ticagrelor/aspirin was significantly lower (12.2% versus 30.0%, P < 0.001). Ticagrelor/aspirin had a lower proportion of HOPR among carriers (11.0% versus 35.6%, P < 0.001), but not among non-carriers (13.5% versus 22.4%, P = 0.17). Ticagrelor was superior to clopidogrel in inhibiting platelet reactivity measured by TEG platelet mapping among patients with acute minor stroke or TIA, particularly in carriers of the CYP2C19 LOF alleles. Large randomised controlled trials are needed to confirm our findings.

The high prevalence of novel coronavirus disease (COVID-19) and inefficient preventive measures taken to curb the disease are significant public health concerns. Rapid and innovative advances in digital media offer opportunities for health education, which could result in increased preventive behaviors. This study assessed preventive behaviors against contracting COVID-19 and tested mediation pathways linking four types of digital media consumption (social media, mobile social networking apps [MSNs], online news media, and social live steaming services [SLSSs]) to preventive behaviors, mediated by worry. Results from an online survey (

Background and Purpose: We aimed to evaluate the impact of cortical microinfarcts (CMIs) on functional outcome after endovascular treatment in patients with acute ischemic stroke. Methods: In a multicenter registration study for RESCUE-RE (a registration study for Critical Care of Acute Ischemic Stroke After Recanalization), eligible patients with large vessel occlusion stroke receiving endovascular treatment, who had undergone 3T magnetic resonance imaging on admission or within 24 hours after endovascular treatment were analyzed. We evaluated the presence and numbers of CMIs with assessment of axial T1, T2-weighted images, and fluid-attenuated inversion recovery images. The primary outcome was functional dependence or death defined as modified Rankin Scale scores of 3 to 6 at 90 days. Secondary outcomes included early neurological improvement, any intracranial hemorrhage, symptomatic intracranial hemorrhage, and mortality. We investigated the independent associations of CMIs with the outcomes using multivariable logistic regression in overall patients and in subgroups. Results: Among 414 patients (enrolled from July 2018 to May 2019) included in the analyses, 96 (23.2%) patients had at least one CMI (maximum 6). Patients with CMI(s) were more likely to be functionally dependent or dead at 90 days, compared with those without (55.2% versus 37.4%; P P =0.04) and multiple CMIs (CMIs ≥2; adjusted odds ratio, 7.41 [95% CI, 2.48−22.17]; P Conclusions: Acute large vessel occlusion stroke patients receiving endovascular treatment with CMI(s) were more likely to have a poor functional outcome at 90 days, independent of patients’ characteristics. Such associations may be dose-dependent. Registration: URL: http://www.chictr.org.cn ; Unique identifier: ChiCTR1900022154.

Chemotherapy-induced alopecia is a common and emotionally traumatic side effect on breast cancer patients. In order to make up for the deficiency of measuring tools in China, our study aims at translating the chemotherapy-induced alopecia distress scale (CADS) into Chinese and evaluating the psychometric properties of the Chinese version of CADS (CADS-C) in breast cancer patients. The validity and reliability of CADS-C were measured by a questionnaire survey among 301 breast cancer patients from Chinese mainland. Construct validity was assessed through factor analysis and contrasted group comparisons. The validity of the content was examined by an experts group. The internal consistency and test–retest reliability were evaluated by calculating Cronbach’s alpha and the intraclass correlation coefficient. The content validity index was 0.94; a structure with three factors was revealed by exploratory factor analysis which explained 65.40% of the variance and proved by confirmatory factor analysis. The contrasted group comparisons showed significant differences among different degrees of alopecia. The average variance extracted and composite reliability and correlations between CADS and body image, quality of life and self-esteem proved the convergent validity. The Cronbach’s alpha and the intraclass correlation coefficient of the total scale were 0.90 and 0.89 respectively, indicating satisfactory internal consistency and time stability. The scale appears to be a reliable and valid tool to measure chemotherapy-induced alopecia distress among breast cancer patients in China.

During the COVID-19 epidemic, the treatment of critically ill patients has been increasingly difficult and challenging. During the epidemic, some patients with neurological diseases also have COVID-19, which could be misdiagnosed and cause silent transmission and nosocomial infection. Such risk is high in a neurological intensive care unit (NCU). Therefore, prevention and control of epidemic in critically ill patients is of utmost importance. The principle of NCU care should include comprehensive screening and risk assessment, weighing risk against benefits and reducing the risk of COVID-19 transmission while treating patients as promptly as possible.

This study aims to evaluate the effects of prolonged expressive writing on health outcomes in breast cancer patients undergoing chemotherapy to help understand how the dosage of an expressive writing intervention might moderate its effects. A total of 112 breast cancer patients undergoing chemotherapy were randomly allocated to the expressive writing group (n = 56) or the prolonged expressive writing group (n = 56). The expressive writing group received the standard expressive writing intervention based on Pennebaker’s prompt to write for at least 20 min over four consecutive days (4 sessions). The prolonged expressive writing group used a modified prompt: write for at least 20 min 3 times a week over a 4-week period (12 sessions); patients could choose whether to write on consecutive days or not. All participants were required to write about their stressor-related upsetting or traumatic feelings about breast cancer. Outcomes were assessed and compared at baseline, as well as 1 month, 3 months, and 6 months postintervention. There was no significant difference in the patients’ quality of life, or physical and psychological wellbeing between the expressive writing group and the prolonged expressive writing group at any time point (all p > .05). The quality of life of breast cancer patients significantly decreased in the two groups over time (F = 40.64, p

Stroke is the third leading cause of long-term disability. Effective stroke rehabilitation should be provided to patients with a moderate or severe stroke so as to achieve functional recovery. Also, stroke rehabilitation is moving towards more intense therapy models that incorporate technologies such as robotics and computer games. Evidence-based guidelines are useful for promoting the best possible clinical practices. This guideline summarises the modes of stroke rehabilitation in China—three-stage rehabilitation network, rehabilitation of stroke dysfunction, training for activities of daily living, stroke complications and rehabilitation care. The aim of this guideline was to provide a synopsis of best clinical practices in the stroke rehabilitation of adult patients in China.

Previous studies suggested that serine can promote the synthesis of selenoproteins and the interaction, transformation, and replacement of serine, cysteine, and selenocysteine have been observed in the human body. This study was designed to clarify whether the dietary intakes of serine and sulfate-containing amino acids (SAAs) could directly affect the selenium (Se) nutritional status or the level of milk Se in lactating women. Breast milk and plasma samples were collected from a total of 264 lactating Chinese women when they revisited their local hospital at the 42nd day postpartum to detect the concentration of Se with ICP-MS and the content of selenoprotein P (SEPP1) and the activity of glutathione peroxidase 3 (GPX3) in the plasma by ELISA. The daily Se intake by each subject was calculated based on her own plasma Se concentration. The 24-h dietary record data for 3 consecutive days were collected to calculate their dietary intakes of protein together with each amino acid daily based on the China Food Composition Tables (CFCT). Ordinal polytomous logistic regression was applied to examine the determinants of BMI values for lactating women. For all subjects, the concentration of plasma SEPP1 and milk Se of participants with insufficient Se intake were significantly associated with the dietary intake of serine and 2 SAAs (methionine and cystine), respectively (P 0.05). No significant correlation was found between each amino acid related to the synthesis of endogenous serine and every biomarker of the Se nutrition status in subjects with an insufficient dietary protein intake (P 0.05). The ordinal logistic regression analysis showed that dietary protein intake (ordinal OR 1.012, 95% CI = 0.004-0.020, P = 0.002) and plasma SEPP1 (ordinal OR 0.988, 95% CI = - 0.023 to - 0.001, P = 0.036) affected the BMI value together in these lactating women. In conclusion, dietary serine and SAAs were found to directly affect the nutritional status, and both high protein intake and low plasma SEPP1 might be the health risks in these lactating Chinese women.

Background: A single index of body mass index (BMI) may not fully address its impact on anti-platelet therapy. We aimed to elucidate the combined impact of BMI and dysglycemia expressed by glycated albumin (GA) on efficacy of clopidogrel-aspirin therapy among minor stroke (MS) or transient ischemic attack (TIA) patients. Results: Patients with overweight/obesity and low GA levels still benefited from clopidogrel-aspirin therapy for stroke recurrence (Hazard ratio [HR]: 0.48, 95 % confidence interval [CI]: 0.28–0.82), so did those with high GA levels but low/normal weight (HR: 0.67, 95 % CI: 0.45–0.99). However, patients with both overweight/obesity and high GA levels did not benefit from clopidogrel-aspirin therapy (HR: 0.89, 95 % CI: 0.59–1.33). Conclusions: Compared with aspirin alone, efficacy of clopidogrel-aspirin therapy for stroke still exists in overweight/obesity patients with normal glycemic control. Methods: In Clopidogrel in High-Risk Patients with Acute Nondisabling Cerebrovascular Events trial, 3044 patients with available baseline GA were recruited. Low/normal weight and overweight/obesity were defined as BMI < 25 kg/m2 and ≥ 25 kg/m2, respectively. Elevated and low GA levels were defined as GA levels > 15.5 % and ≤ 15.5 %, respectively. The primary outcome was stroke recurrence during the 90-day follow-up.

AimStroke is the leading cause of disability and death in China. Ischaemic stroke accounts for about 60%–80% of all strokes. It is of considerable significance to carry out multidimensional management of ischaemic cerebrovascular diseases. This evidence-based guideline aims to provide the latest detailed and comprehensive recommendations on the diagnosis, treatment and secondary prevention of ischaemic cerebrovascular diseases.MethodsWe had performed comprehensive searches of MEDLINE (via PubMed) (before 30 June 2019), and integrated the relevant information into charts and distributed to the writing group. Writing group members discussed and determined the recommendations through teleconference. We used the level of evidence grading algorithm of Chinese Stroke Association to grade each recommendation. The draft was reviewed by the Guideline Writing Committee of Chinese Stroke Association Stroke and finalised. This guideline is fully updated every 3 years.ResultsThis evidence-based guideline is based on the treatment, care and prevention of ischaemic cerebrovascular diseases, which emphasises on pathogenesis evaluation, intravenous thrombolysis, endovascular therapy, antiplatelet therapy, prevention and treatment of complications, and risk factor management.ConclusionsThis updated guideline presents a framework for the management of ischaemic cerebrovascular diseases. Timely first-aid measures, professional care in the acute stage, and proactive secondary prevention will be helpful to patients.

In this paper, we discuss our approach to designing a board game, the Green Economy, that promotes systems thinking. We anchored our game design process on design-by-analogy and rapid prototyping concepts by taking a modular approach to overcome the trade-off between realism and simplicity. The unique feature of the Green Economy enables players to change the rules of the game during the gameplay, which gives them a partial design opportunity. The theme, sustainable development, was chosen to challenge the players’ systems thinking in sustainable development. Systems thinking enables us to understand and face the complex challenges in global and networked social structures. Our design experience demonstrates the benefit of designing dynamic game elements that involve both strategic gameplay and game (re)design through systems thinking.

BackgroundThe effect of cerebral small vessel disease (CSVD) and intracranial arterial stenosis (ICAS) on stroke outcomes remains unclear.MethodsData of 1045 patients with minor stroke or transient ischaemic attack (TIA) were obtained from 45 sites of the Clopidogrel in High-Risk Patients with Acute Non-disabling Cerebrovascular Events (CHANCE) trial. We assessed the associations of burdens of CSVD and ICAS with new strokes and bleeding events using multivariate Cox regression models and those with modified Rankin Scale (mRS) scores using ordinal logistic regression models.ResultsAmong the 1045 patients, CSVD was present in 830 cases (79.4%) and ICAS in 460 (44.0%). Patients with >1 ICAS segment showed the highest risk of new strokes (HR 2.03, 95% CI 1.15 to 3.56, p=0.01). No association between CSVD and the occurrence of new strokes was found. The presence of severe CSVD (common OR (cOR) 2.01, 95% CI 1.40 to 2.89, p1 ICAS segment (cOR 2.15, 95% CI 1.57 to 2.93, pInterpretationCSVD is associated with more disability and bleeding events, and ICAS is associated with an increased risk of stroke and disability in patients with minor stroke and TIA at 3 months. CSVD and ICAS may represent different vascular pathologies and play distinct roles in stroke outcomes.Trial registration numberNCT00979589

Background S100A8/A9 is implicated in inflammation mechanisms related to atherosclerosis and plaque vulnerability, but it remains unclear whether S100A8/A9 is associated with the prognosis of ischemic stroke. The aim of this study was to investigate these associations in 2 independent multicenter cohorts. Methods Plasma S100A8/A9 concentrations at baseline were measured among 4785 patients with ischemic stroke from 2 independent cohorts: Infectious Factors, Inflammatory Markers, and Prognosis of Acute Ischemic Stroke (IIPAIS) and China Antihypertensive Trial in Acute Ischemic Stroke (CATIS). The primary outcome was a composite outcome of death or major disability at 3 months after ischemic stroke. Secondary outcomes were major disability, death, and a composite outcome of death or vascular events. Results Among the combined participants of IIPAIS and CATIS, the adjusted odds ratios associated with the highest quartile of plasma S100A8/A9 were 2.11 (95% CI, 1.66–2.68) for the primary outcome and 1.62 (95% CI, 1.27–2.07) for the secondary outcome of major disability; adjusted hazard ratios were 4.14 (95% CI, 2.10–8.15) for the secondary outcome of death and 2.08 (95% CI, 1.38–3.13) for the composite outcome of death or vascular events. Each SD increase of log-transformed S100A8/A9 was associated with 28% (95% CI, 18%–39%; P Conclusions High plasma S100A8/A9 concentrations at baseline were independently associated with increased risks of adverse clinical outcomes at 3 months after ischemic stroke, suggesting that S100A8/A9 might have a role as a prognostic marker of ischemic stroke.

Asphalt pavement is a multi-layer continuous structure with an interlayer bonding condition that can greatly influence its bearing capacity and must be monitored over the whole service length. Hence, proper maintenance and rehabilitation measures are taken and better feedback can be made for the design. Nevertheless, asphalt pavement interlayer bonding condition plays a hidden role and is difficult to quantify unless applying damage discovery techniques like drilling core process. The original structure is destroyed by the damage detection approaches, the results also suffer from low coverage rate and high dispersion, therefore, actual engineering demands are not satisfied. Here, some recent methods are briefly presented based on asphalt pavement interlayer bonding condition non-destructive diagnosis and their restrictions are discussed. Moreover, a new technique is provided with the merits of utilizing only mechanical simulation and overall superficial distresses condition evaluation index with high accuracy. This simulation procedure adopts bridging principles to build a connection between asphalt pavement superficial distresses and asphalt pavement micro mechanic parameters. It uses a structure behavior equation capable of identifying four typical deterioration modes and has specific physical meaning parameters to predict asphalt pavement overall superficial distresses. The established model allows the asphalt pavement interlayer bonding acting as a hypothetical input variable. The known input variables include easily obtainable design parameters of the asphalt pavement structure, historical superficial distresses, surface deflection, traffic load, and environmental factors, however, the output is the predicted asphalt pavement overall superficial distresses condition. The asphalt pavement interlayer bonding condition is defined by contrasting the theoretical asphalt pavement overall superficial distresses conditions between its complete bonding condition and discontinuous bonding condition to a certain degree. Examples in parts of the Jingha highway show that great discrepancies exist between theoretical asphalt pavement overall superficial distress in the condition of complete interlayer bonding and actual asphalt pavement overall superficial distress. The actual asphalt pavement sections in overall superficial conditions are deteriorated much faster than normal ones. By setting the asphalt pavement interlayer bonding continuations as 75% and 90% for K315–K316 section and K316–K317 section, respectively, the revised and predicted overall superficial distresses of the theoretical asphalt pavement are consistent with the real ones. The hypothetical values are then chosen as the diagnosed quantitative asphalt pavement interlayer bonding continuations and are proven to be correct through drilling core sample results. The analyses in other sections show that middle traffic volume asphalt pavement structure is quite weak when its interlayer bonding continuation is 70%, and under this value, its bearing capacity is almost equivalent to the situation when its interlayer bonding continuation is 0%; when its interlayer bonding continuation is 85% or more, its bearing capacity is almost equivalent to the situation where its interlayer bonding continuation is 100%. This proposed non-destructive diagnosis method for asphalt pavement interlayer bonding condition is effective and shows good application prospects in road engineering.

ObjectiveGastrointestinal (GI) bleeding in patients who had a stroke is strongly associated with a higher risk of death and loss of independence. However, it is unknown whether GI bleeding increases risk for recurrence of stroke. In this study, we assess the potential relationship between GI bleeding and stroke recurrence in patients within 12 months of an acute ischaemic stroke (AIS), using the China National Stroke Registry (CNSR).MethodsThis study included 22 216 patients who had an ischaemic stroke included in the CNSR from 2007 to 2008. We analysed baseline patient characteristics, GI bleeding and outcomes of patients who had an AIS, specifically stroke recurrence at 3, 6 and 12 months. We used multivariable logistic regression to evaluate a possible association between GI bleeding and stroke recurrence.ResultsOf the 12 415 patients included in our study, 12.3%, 15.5% and 17.7% had a stroke recurrence at 3, 6 and 12 months, respectively. GI bleeding was an independent stroke recurrence risk factor in patients after ischaemic stroke at 3 months (adjusted OR 1.481, 95% CI 1.118 to 1.962), 6 months (adjusted OR 1.448, 95% CI 1.106 to 1.896) and 12 months (adjusted OR 1.350; 95% CI 1.034 to 1.763).ConclusionGI bleeding was associated with the increased risk of stroke recurrence after an AIS.

GILZ expression is induced by glucocorticoids (GCs) and is involved in the mechanism of airway epithelial cell repair in patients with asthma. The present study aimed to investigate the role of miR-222-3p/GILZ pathway in treatment of airway epithelial cell repair by GCs. 9HTE cells were treated by 10 µmol/L dexamethasone (Dex) for 6, 12, and 24 hours (h). MiR-222-3p mimic and GILZ were used for cell transfection. Cell vitality, migration, and invasion were detected by methyl-thiazolyl tetrazolium (MTT), wound healing, and Transwell. The targeting relationship between miR-222-3p and GILZ was predicted by TargetScan and further confirmed by dual-luciferase reporter assay. The expressions of relative mRNAs or proteins were detected by Western blot and quantitative polymerase chain reaction (qPCR). The results showed that Dex treatment up-regulated the GILZ expression level but inhibited the levels of p-Raf1, p-MEK1/2, p-ERK1/2, and miR-222-3p of the cells, moreover, it also inhibited cell activity, migration, and invasion in a time-dependent manner. MiR-222-3p specifically targeted GILZ. MiR-222-3p mimic ameliorated the cell viability, migration, and invasion reduced by Dex treatment, increased the expression levels of p-Raf1 and p-MEK1/2, p-ERK1/2, and partially reversed the effects of GILZ overexpression on the above indexes. Moreover, GILZ showed the opposite effects to miR-222-3p. MiR-222-3p activated MAPK signaling pathway through inhibiting the GILZ expression, thus promoting the cell viability, migration, and invasion previously reduced by Dex.

Purpose: Hesperidin has anti-inflammatory and anti-oxidant stress effects, but its functions in chronic obstructive pulmonary disease (COPD) remains unknown. This study analyzed the role of hesperidin in COPD mice, aiming to provide a basis for the hesperidin application.Materials and methods: Mice were injected with cigarette smoke extract (CSE) to construct COPD models and then treated with budesonide or hesperidin. Hematoxylin-eosin (HE) and TUNEL assays were used to observe the pathological changes and cell death of lung tissue. The levels of interleukin (IL)-6, IL-8, malondialdehyde (MDA), superoxide dismutase (SOD), and catalase (CAT) in bronchoalveolar lavage fluid (BLAF), as well as myeloperoxidase (MPO) content in lung tissues were confirmed. The expression levels of SIRT1, PGC-1α, and p65 proteins were measured by western blotting (WB) analysis.Results: CSE induced inflammatory cell infiltration and cell death in the lung tissues of mice, whereas budesonide and hesperidin effectively alleviated these pathological changes. The levels of IL-6, IL-8, and MDA in BLAF and pulmonary MPO content in the COPD mice were effectively increased, while the levels of SOD and CAT in BLAF were decreased, which could be reversed by budesonide and hesperidin. Moreover, the addition of budesonide or hesperidin reliably accelerated the expression levels of PGC-1α and SIRT1 but suppressed the phosphorylation of p65 in COPD mice. In general, high-dose hesperidin had a stronger regulatory effect on COPD mice.Conclusions: Hesperidin alleviated inflammation and oxidative stress responses in CES-induced COPD mice, associated with SIRT1/PGC-1α/NF-κB signaling axis, which might become a new direction for COPD treatment.
