    Abstract Background: Heart failure with preserved ejection fraction (HFpEF), a major cause of morbidity and mortality in patients with type 2 diabetes mellitus (T2DM), is frequently coexisted with obesity, poor glycemic, blood pressure (BP), and/or lipid control. We aimed to investigate the associations of nonalcoholic fatty liver disease (NAFLD) and its advanced fibrosis with HFpEF according to obesity, glycated hemoglobin A1c (HbA1c), BP, and low-density lipoprotein cholesterol (LDL-C) goal achievement status in T2DM patients.
    Methods: A total of 2,418 T2DM patients who were hospitalized were cross-sectionally assessed. Liver fibrosis was evaluated by non-invasive biomarkers. Logistic regression analysis was used to evaluate the independent and combined associations of fibrosis status and diabetic care goal attainments with HFpEF risk.
    Results: Simple steatosis was not associated with HFpEF risk compared with patients without steatosis, while advanced liver fibrosis was found to have significantly higher odds for HFpEF risk (odds ratio,1.59; 95% confidence interval, 1.22-2.08). Advanced fibrosis in NAFLD was significantly associated with an increased risk of HFpEF, regardless of obesity status, HbA1c, BP, and LDL-C goal achievement status. P values for the interactions between fibrosis status and HbA1c control status, fibrosis status and BP control status, fibrosis status and LDL-C control status, and fibrosis status and body mass index (BMI) status on HFpEF risk were 0.021, 0.13, 0.001, and 0.23, respectively.
    Conclusion: In patients with T2DM, advanced hepatic fibrosis was significantly associated with HFpEF risk, irrespective of obesity status, HbA1c, BP, and LDL-C goal attainment status. Further, HbA1c and LDL-C goal attainment status modified this association.

    Abstract Background Low muscle mass/sarcopenia has been associated with poor prognosis in many diseases, but its clinical significance in pyogenic liver abscess (PLA) remains unclear. The purpose of this study is to investigate the relationship between muscle mass and prognosis of patients with PLA. Methods A total of 154 adult patients with PLA hospitalized at Tongji Hospital (Wuhan, Hubei, China) between October 2011 and June 2021 were included in this retrospective analysis. Muscle-fat related indicators were measured by computed tomography (CT) images at the third lumbar vertebra (L3) level. The data of patients between the sarcopenia group and non-sarcopenia group were compared. Multivariate logistic regression and receiver operating characteristic (ROC) curve analyses were performed. Results The skeletal muscle index (SMI) was independently associated with adverse outcomes (95% CI [0.649–0.954], P = 0.015) of PLA in multivariate logistic regression analysis. This conclusion held true in sex-specific subgroup analysis. ROC analysis indicated that SMI may predict adverse outcomes in both male (area under the ROC curve [AUC], 0.718; cut-off, 52.59; P < 0.001) and female (AUC, 0.714; cut-off, 38.39; P = 0.017) patient populations. Conclusions Sarcopenia serves as an independent risk factor for poor prognosis in PLA and patients with sarcopenia may be more prone to adverse outcomes.

    Abstract Alterations in zinc transporter expression in response to zinc loss protect cardiac cells from ischemia/reperfusion (I/R) injury. However, the underlying molecular mechanisms how cardiac cells sense zinc loss remains unclear. Here, we found that zinc deficiency induced ubiquitination and degradation of the protein inhibitor of activated STAT3 (PIAS3), which can alleviate myocardial I/R injury by activating STAT3 to promote the expression of ZIP family zinc transporter genes. The RING finger domain within PIAS3 is vital for PIAS3 degradation, as PIAS3-dRing (missing the RING domain) and PIAS3-Mut (zinc-binding site mutation) were resistant to degradation in the setting of zinc deficiency. Meanwhile, the RING finger domain within PIAS3 is critical for the inhibition of STAT3 activation. Moreover, PIAS3 knockdown increased cardiac Zn

    Abstract Abstract A considerable chronic disease burden existed in people with normal body mass index (BMI), it is imperative to study the prevailing trends in abdominal obesity among Chinese people with normal BMI. Hence, we aimed to analyze updated prevalence data on abdominal obesity trends among Chinese adults with a normal BMI. We used data from the China Health and Nutrition Survey (CHNS) conducted between 1993 and 2015. Abdominal obesity is defined as waist circumference (WC) ≥ 90 cm for men and ≥ 80 cm for women following the International Diabetes Federation recommendations for Asians. Over the 23-year period, the age-standardized mean WC values showed a significant increasing trend among Chinese adults with BMI < 25 kg/m2, with the mean value increased from 74.0 cm to 78.5 cm (P for trend < 0.0001). During the period of 1993–2015, the age-standardized prevalence of abdominal obesity increased from 12.1 to 26.0% (P for trend < 0.0001). Significant increases were observed in both sexes, all age groups, rural and urban residents, and all educational attainment groups (all P for trends < 0.0001), with a greater relative increase noted among men, younger participants, and rural residents. Similar significant trends were noted when a more stringent BMI < 23 kg/m2 cut point (Asian cut point) was applied. A low magnitude of overlap existed between abdominal obesity and general obesity, irrespective of the criteria used. The mean WC and the prevalence of abdominal obesity among Chinese adults with normal BMI increased continuously from 1993 to 2015. The upward trends were noted in both sexes, all age groups, rural and urban regions, and all educational attainment groups. Our estimates emphasize the importance of adding WC in addition to BMI as measures to monitor obesity prevalence.

    Abstract Abstract The contribution of nonalcoholic fatty liver disease (NAFLD) to all-cause and cardiovascular mortality remains controversial. Sarcopenia, a measure of muscle mass, strength and function, may identify which persons are most at risk for adverse effects of NAFLD. We aimed to test the hypothesis that sarcopenia modifies the associations between NAFLD and all-cause and cardiovascular mortality. A total of 2446 older adults (≥ 60 years) from the third National Health and Nutrition Examination Survey were enrolled. Their mortality data were linked to death certificates in the National Death Index. Sarcopenia was defined as having low skeletal muscle mass together with slow gait speed, which captures both muscle mass and muscle function. Ultrasound tests were used for the assessment of hepatic steatosis. During follow-up (median 16.8 years), 1530 older subjects died from any cause, of which 379 were cardiovascular-related. All-cause and cardiovascular mortality rates were 4.31 and 1.07 per 100 person-years, respectively. In a multivariate model, using participants without NAFLD and sarcopenia as the reference group, individuals with both NAFLD and sarcopenia had 1.69 times [95% confidence interval (CI) 1.23–2.31] and 2.17 times (95% CI 1.33–3.54) higher risks of all-cause and cardiovascular mortality, respectively. However, NAFLD persons without sarcopenia had hazard ratios for all-cause and cardiovascular mortality similar to those of the reference group. Sarcopenia modified the associations of NAFLD with all-cause and cardiovascular mortality. Sarcopenia may identify older adults who are at the highest risk for adverse outcomes associated with NAFLD.

    Abstract The utilization of spark induced compression ignition (SICI) is a proven method to extend the operation load range, improve thermal efficiency as well as ensure robust control of the combustion process of homogeneous charge compression ignition (HCCI). However, negative valve overlap (NVO), intake-charge heating, and other methods of achieving SICI and the knock occurrence limit its load range and industrialization. In this paper, the effects of ethanol blending with different excess air ratios (λ) on the knock and combustion characteristics, output power, indicated thermal efficiency (ITE), and emissions were investigated in a high compression ratio (CR), single-cylinder, four-stroke SICI engine. The experimental results show that weak stratification increases the knock intensity, while strong stratification suppresses knock tendency at the stoichiometric ratio. Ethanol addition can suppress knock tendency, reduce the randomness of knock and improve the combustion stability. In comparison with pure gasoline, the IMEP and ITE of E100 increase by 6.3–15.1% and 6.8–9.1% at different λ, respectively. For conditions with low ethanol blending ratio (such as 0% or 10%) and λ with 1.0 or 1.2, knock is the limitation to further improve its thermal efficiency, while fuel economy is more affected by the overall combustion phase with an increase in ethanol blending ratio and λ. There exists a non-monotonic correlation between the NOₓ, THC, and CO emissions and the ethanol blending ratio due to the competing effects of oxygen-containing properties, higher latent heat of evaporation (LHE), intake-charge cooling effect, and higher combustion temperature. Ethanol blending, except for E100, does not exhibit the PN reduction tendency. Knock deteriorates PN emissions, especially in nucleation mode, and ethanol blending shifts its size distribution towards nucleation mode.

    Abstract Increasing the compression ratio of gasoline engines is a promising method to increase the engine's fuel economy. However, engine knock caused by auto-ignition is still a large obstacle to improving thermal efficiency and engine load for high compression ratio hybrid engines. Spark induced compression ignition (SICI) is an effective way to utilize auto-ignition to solve the aforementioned problems. Meanwhile, ammonia, a carbon-free fuel, with an outstanding antiknock property, has the great potential to be used in SICI mode. In this study, the effects of ammonia addition on knock suppression, combustion characteristics, thermal efficiency, and emission performance were investigated in a high compression ratio (15.5), four-valve, single-cylinder gasoline engine under SICI combustion mode. In experiments, gasoline was directly injected into the cylinder while ammonia was injected into the intake port. The results show that blending ammonia could resist engine knock and improve thermal efficiency. Within the knock limitation, the duration of flame propagation under ammonia blending conditions could be shortened and meanwhile, the auto-ignition becomes weakened compared with pure gasoline. Benefiting from combustion phase optimization, the thermal efficiency and engine load could be increased or maintained at optimal ammonia blending ratio. The maximum increase of thermal efficiency and engine load is 2.46% and 0.2 MPa respectively. Moreover, the increased engine load can extend the limit of the ammonia blending ratio. For nitrogen emissions, blending ammonia results in NOₓ emission deterioration due to the formation of fuel-type NOₓ. NOₓ emission has a weak dependence on the ammonia blending ratio, and the trend of NOₓ emission varied with spark timing is opposite to pure gasoline conditions, which is closely related to the pressure sensitivity of fuel-type NOₓ. Ammonia slip was also detected in the engine exhaust because of the incomplete combustion.

    Abstract Thyroid cancer is the most pervasive disease in the endocrine system and is getting extensive attention. The most prevalent method for an early check is ultrasound examination. Traditional research mainly concentrates on promoting the performance of processing a single ultrasound image using deep learning. However, the complex situation of patients and nodules often makes the model dissatisfactory in terms of accuracy and generalization. Imitating the diagnosis process in reality, a practical diagnosis-oriented computer-aided diagnosis (CAD) framework towards thyroid nodules is proposed, using collaborative deep learning and reinforcement learning. Under the framework, the deep learning model is trained collaboratively with multiparty data; afterward classification results are fused by a reinforcement learning agent to decide the final diagnosis result. Within the architecture, multiparty collaborative learning with privacy-preserving on large-scale medical data brings robustness and generalization, and diagnostic information is modeled as a Markov decision process (MDP) to get final precise diagnosis results. Moreover, the framework is scalable and capable of containing more diagnostic information and multiple sources to pursue a precise diagnosis. A practical dataset of two thousand thyroid ultrasound images is collected and labeled for collaborative training on classification tasks. The simulated experiments have shown the advancement of the framework in promising performance.
