Abstract
Objective: To evaluate the related factors of gallstones related gallbladder intraepithelial neoplasia(GBIN) and establish the prediction models for gallstones related GBIN. Methods: The clinicopathological data of 750 patients who underwent cholecystectomy for gallstones at Department of Hepatobiliary Surgery of the First Affiliated Hospital of Xi'an Jiaotong University from January 2013 to December 2018 and the postoperative pathological examination showed chronic cholecystitis or GBIN were analyzed retrospectively,including 150 cases of gallstones with GBIN and 600 cases of gallstones with chronic cholecystitis.There were 264 males and 486 females with age of (51.3±14.5) years (range: 18 to 90 years).The related factors for gallstones related GBIN were screened by χ2 test and Logistic regression model,and the prediction models were established based on independent related factors and internal validation was conducted.The original data were randomly divided into a training cohort(526 cases) and a validation cohort(224 cases) at a ratio of 7∶3,and the nomogram and tree augmented naïve Bayes were conducted to establish the prediction model for gallstones related GBIN.The consistency index(C-index),calibration chart,area under the receiver operating characteristic curve(AUC) and confusion matrix were used to evaluate the prediction performance of the two models. Results: Univariate analysis showed that age,gallstones history(years),gallbladder size,whether the gallbladder mucosa smooth or not,whether the gallbladder wall thickened or not,gallstones diameter,and number of gallstones were related factors for the occurrence of gallstones related GBIN (χ²=19.957,8.599,9.724,9.301,8.341,15.288,9.169,all P<0.05).Multivariate analysis showed that age (OR=2.23,95%CI:1.50-3.31,P<0.01),gallbladder size (OR=2.11,95%CI:1.17-3.80,P=0.013),whether the gallbladder mucosa smooth or not (OR=1.80,95%CI=1.13-2.88,P=0.014),gallstones diameter(OR=2.98,95%CI:1.71-5.21,P<0.01),and number of gallstones (OR=2.14,95%CI=1.34-3.42,P<0.01) were independent related factors for the occurrence of gallstones related GBIN; the C-index of the nomogram in training cohort and validation cohort were 0.708 and 0.696,respectively.The AUC of the two models in training cohort were 70.60% and 70.73%,and in validation cohort were 68.14% and 67.47%,respectively.The accuracy of the two models in training cohort were 69.96% and 70.72%,and in validation cohort were 66.96% and 67.41%,respectively. Conclusion: Age,gallbladder size,whether the gallbladder mucosa smooth or not,gallstones diameter and number of gallstones are independent related factors for the occurrence of gallstones related GBIN,and the nomogram and tree augmented naïve Bayes prediction models based on the above factors can be used to predict the occurrence of GBIN.

Abstract
Blastocystis hominis is a common intestinal protozoan parasite. Most individuals with B. hominis infections have no apparent clinical symptoms; however, a few patients, notably those with co-infections or impaired immune system function may present abdominal pain, diarrhea, nausea, vomiting, and even death. This paper reviews the co-infections of B. hominis and other pathogens and comorbidity of B. hominis infections and other diseases, so as to provide insights into the management of B. hominis infections.

Abstract
Objective: Environmental factors can influence obesity by epigenetic mechanisms. The aim of this study was to investigate obesity-related epigenetic changes and the potential for reversal of these changes in the liver of Göttingen minipigs subjected to diet interventions. Methods: High-throughput liquid hybridization capture-based bisulfite sequencing (LHC-BS) was used to quantify the methylation status of gene promotor regions in liver tissue in three groups of male castrated Göttingen minipigs: a standard chow group (SD, N = 7); a group fed high fat/fructose/cholesterol diet (FFC, N = 10) and a group fed high fat/fructose/cholesterol diet during 7 months and reversed to standard diet for 6 months (FFC/SD, N = 12). Expression profiling by qPCR of selected metabolically relevant genes was performed in liver tissue from all pigs. Results: The pigs in the FFC diet group became morbidly obese. The FFC/SD diet did not result in a complete reversal of the body weight to the same weight as in the SD group, but it resulted in reversal of all lipid related metabolic parameters. Here we identified widespread differences in the patterning of cytosine methylation of promoters between the different feeding groups. By combining detection of differentially methylated genes with a rank-based hypergeometric overlap algorithm, we identified 160 genes showing differential methylation in corresponding promoter regions in the FFC diet group when comparing with both the SD and FFC/SD groups. As expected, this differential methylation under FFC diet intervention induced de-regulation of several metabolically-related genes involved in lipid/cholesterol metabolism, inflammatory response and fibrosis generation. Moreover, five genes, of which one is a fibrosis-related gene (MMP9), were still perturbed after diet reversion. Conclusion: Our findings highlight the potential of exploring diet-epigenome interactions for treatment of obesity.

Abstract
This study was performed to explore the value of a machine with built-in speckle tracking automated functional imaging (AFI) in predicting the severity of coronary artery lesions in patients with suspected stable coronary artery disease (SCAD) with normal wall motion. One hundred forty-three consecutive patients with clinically suspected SCAD with normal wall motion were included. Multiple parameters, including global longitudinal peak strain, post-systolic index (PSI) and peak strain dispersion, were automatically analyzed with AFI. Territorial longitudinal strain (TLS) and territorial PSI (TPSI) were also calculated. Receiver operating characteristic curve analyses revealed that global longitudinal peak strain and PSI were superior to other parameters in detecting left main or three-vessel SCAD. A combination of TLS and TPSI could improve diagnostic performance in identifying significant stenotic left anterior descending and right coronary arteries. In conclusion, 2-dimensional speckle tracking AFI can rapidly provide multiple parameters for detecting significant coronary artery stenosis with high accuracy in patients suspected of having SCAD with normal wall motion.

Abstract
One of the main challenges in ultrafast material science is to trigger phase transitions with short pulses of light. Here we show how strain waves, launched by electronic and structural precursor phenomena, determine a coherent macroscopic transformation pathway for the semiconducting-to-metal transition in bistable Ti3O5 nanocrystals. Employing femtosecond powder X-ray diffraction, we measure the lattice deformation in the phase transition as a function of time. We monitor the early intra-cell distortion around the light absorbing metal dimer and the long range deformations governed by acoustic waves propagating from the laser-exposed Ti3O5 surface. We developed a simplified elastic model demonstrating that picosecond switching in nanocrystals happens concomitantly with the propagating acoustic wavefront, several decades faster than thermal processes governed by heat diffusion.

Abstract
1. Granulosa cells (GCs) are involved in folliculogenesis, follicular development, and atresia. Previous studies have shown that microRNA-181a-5p (miR-181a-5p) and sirtuin 1 (SIRT1) are involved in GC proliferation and apoptosis, and SIRT1 has been predicted as one target of miR-181a-5p. However, there are few studies with poultry.2. Quantitative real-time PCR (qRT-PCR) was used to detect the expression level of miR-181a-5p in granulosa layers during geese ovarian follicular development. A methyl thiazolyl tetrazolium (MTT) assay was performed to assess the viability of geese granulosa cells treated with miR-181a-5p mimic or inhibitor. The binding sites between the SIRT1 3'-UTR region and miR-181a-5p were evaluated using a luciferase reporter assay system. SIRT1 mRNA levels were detected using qRT-PCR after transfection with miR-181a-5p mimic and inhibitor.3. The miR-181a-5p suppressed geese GC viability and regulated the mRNA expression of viability-related genes in geese GCs. SIRT1 was a target gene of miR-181a-5p and miR-181a-5p suppressed its mRNA expression.4. The miR-181a-5p may target and inhibit SIRT1 expression, thus suppressing GC viability by regulating viability-related key genes.

Abstract
Objective: To analyze the clinical characteristics, risk factors for critical illness and death of severe adenovirus pneumonia in children, so as to provide clinical evidences for early diagnosis and reliable treatment. Methods: A total of 75 pediatric cases with severe adenovirus pneumonia admitted to Tongji Hospital, Tongji Medical College, Huazhong University of Science and Technology from January to October 2019 were studied. The clinical features, laboratory and imaging data, therapeutic approaches, efficacy of the treatments and prognosis were investigated retrospectively. Patients were divided into severe group and critical group. Chi square test and Mann-Whitney U rank sum test were used to analyze the data of the two groups. The risk factors for critical illness and death were analyzed by univariate and multivariate Logistic regression. Results: Among the 75 children, there were 52 males and 23 females, aged from 3 months to 8 years, including 30 of severe cases and 45 of critical case. The positive rate of adenovirus antigen in nasopharyngeal swab was 21% (15/72), and the positive rate of serum adenovirus IgM antibody was only 13% (10/75). However, the positive rate of adenovirus nucleic acid in nasopharyngeal swab was 75% (21/28). What is more, the positive rates of metagenomics next generation sequencing (mNGS) in plasma and bronchoalveolar lavage fluid were 92% (33/36) and 96% (54/56), respectively, of which 95% (63/66) were confirmed as adenovirus type 7. Relatively high dose of ribavirin and integrated therapeutic approaches (respiratory support, glucocorticoids, immunoglobulin and organ supportive therapies) were used. The recovery rate was 77% (58/75), the improvement rate was 8% (6/75) and the mortality rate was 15% (11/75). The proportion of children with the duration of fever longer than 3 days after ribavirin treatment in the critical group was significantly higher than that in the severe group(51% (18/35) vs. 8% (2/26), χ2=12.949, P<0.05). The risk factors for critical illness were younger than 4 years, longer duration of fever before and after admission to PICU, oxygenation index<300 mmHg (1 mm Hg=0.133 kPa), ferritin>1 000 μg/L, lactate dehydrogenase (LDH)>1 500 U/L, 5 lung lobes involvement, pleural effusion and (or) air leakage (all P<0.05). Among them, 5 lung lobes involvement was the independent risk factor for critical illness (adjusted OR=49.641, 95%CI 4.186-588.618, P=0.002). Risk factors for death included longer duration of fever after being admitted to PICU, oxygenation index<100 mmHg, ferritin>2 000 μg/L, interleukin (IL)-6>100 ng/L, LDH>1 500 U/L, pleural effusion and (or) air leakage (all P<0.05). Among them, IL-6>100 ng/L was the independent risk factor for the mortalities of critically ill children (adjusted OR=16.094, 95%CI 2.059-25.787, P=0.008). Conclusions: The mortality rate of severe pediatric adenovirus pneumonia caused by adenovirus type 7 is high. High positive rates of adenovirus nucleic acid in nasopharyngeal swabs and mNGS in plasma or bronchoalveolar lavage fluid contribute to early diagnosis, and mNGS can also be used for serotyping. Younger children under 4 years of age, persistent fever, extensive pulmonary lesions and significantly increased inflammatory cytokines such as IL-6 are warning indicators for critical illness and poor prognosis. Relatively high dose of ribavirin combined with integrated therapeutic approaches are beneficial for prognosis.

Abstract
OBJECTIVES Motoric cognitive risk syndrome (MCR) is a newly described pre-dementia syndrome characterized by cognitive complaints and slow gait and is associated with numerous adverse outcomes. Previous studies have indicated an association between C-reactive protein (CRP) and cognitive decline, but no clear relationship between CRP and MCR has been reported. The purpose of the study is to examine the associations between CRP with MCR and MCR subtypes. METHODS Participants were 5,642 adults aged ≥60 years from the China Health and Retirement Longitudinal Study (CHARLS). MCR was defined as cognitive complaints and slow gait speed without dementia or impaired mobility. Two subtypes of MCR were defined by whether memory impairment (MI) was also present, such as MCR-MI and MCR-non-MI. MI was evaluated through the immediate recall and delayed recall in a word recall test during the CHARLS and was defined as 1.0 standard deviation or more below the mean values of the test scores in this cohort. RESULTS Of the participants, 421 (7.46%) met the criteria for MCR. After multivariate adjustment, participants with higher CRP levels had an increased likelihood of MCR (fourth quartile: adjusted odds ratio [OR]=1.44; 95% confidence interval [CI]: 1.06-1.95) compared with those in the first quartile group. The OR for MCR-MI was 2.04 (95% CI: 1.35-3.09) for the highest quartile of CRP compared to the lowest quartile. No significant associations between CRP levels and odds of MCR-non-MI were observed. CONCLUSIONS Higher CRP levels were associated with increased odds of prevalent MCR-MI but not MCR-non-MI among community-dwelling older adults.

Abstract
End-of-life tires are an increasingly important environmental burden. Since retreading is only partly possible, safe and economic methods of disposal need to be developed. Pyrolysis of ELTs, and subsequent upgrading/application of the produced energy carriers, is considered a valuable treatment method. In order to design the process, numerous operation units have to be taken into account. Char, vapour and gas are formed in the reactor. The char is purified from ZnO with a leaching process. The pyrolysis vapour is separated into a condensable fraction (oil) and a non-condensable fraction (gas) thanks to a cross-flow condenser with air as indirect cooling medium. The remaining gas is compressed to 6 bar: a part of it is continuously converted in electricity for process use, while another part is stored for power generation at peak demand time. A flowsheet of the process is established and environmental and assessment of investments and production are discussed. For the pyrolytic treatment of 3 ton/hr of ELTs, the required heat for the reactor is 271 kW at 380 °C, provided by electrical heating elements. A reactor volume is determined for a residence time of about 6 h. For the cross-flow condenser, indirectly air-cooled, a heat-transfer area of about 13.2 m2 is required. The compression of the gas the pressurized pyrolytic gas storage tank depends upon the excess pyrolytic gas produced during operation. The char cooler requires a heat-transfer area of 10.2 m2, when indirectly cooled by water. Operating parameters of the leaching and subsequent recovery of Zn2+ complete the design. The product added-value and the large-scale capacity make the process economically viable, although the ROI is between 2 and 3 years.

Abstract
OBJECTIVE To analyze the epidemiological characteristics of malaria in Henan Province from 1950 to 2019, so as to provide the scientific evidence for consolidating malaria elimination achievements in the province. METHODS The epidemiological situation of malaria and demographic data in Henan Province from 1950 to 2019 were collected, and the statistical analyses were performed using a descriptive epidemiological method. The spatial temporal distribution of malaria cases was identified using the software ArcGIS version 10.3. RESULTS During the period from 1950 through 2019, the progress of malaria elimination was divided into 4 stages in Henan Province, including the baseline-survey and key-control stage, morbidity-control and incidence-reduction stage, basic-eradication and achievement-consolidation stage and elimination stage. The spatial distribution of malaria cases shifted from south of the Huai River and the plain regions between the Yellow River and Taihang Mountain to the Huang-Huai-Hai Plain and Nanyang Basin, then was concentrated in eastern part of southern Huai River where Anopheles anthropophagus was distributed, and finally was gradually under control following malaria outbreak in Eastern Henan Plain. In addition, the species of Plasmodium changed from P. vivax, P. falciparum and P. malariae co-endemics to a single P. vivax infection, and the current co-endemics of 5 invasive malaria parasites, and the malaria vectors shifted from co-existence of Anopheles sinensis and An. anthropophagus to An. sinensis alone. CONCLUSIONS There has been a large change in the epidemiological characteristics of malaria in Henan Province from 1950 to 2019. Although malaria has been eliminated in Henan Province, the consolidation of the malaria elimination achievements remain a great challenge due to overseas imported malaria.

Abstract
Abstract
Background
The mortality of coronary heart disease (CHD) can be largely reduced by improving CHD risk factors through facilitating adherence to unhealthy lifestyle modification (UhLM) and secondary preventive medications (SPMs). Current interventions, however, have been unsatisfactory worldwide.
Purpose
To develop an Individualized, Intelligent and Integrated Cardiovascular Application for Risk Elimination system (iCARE) for facilitating adherence to UhLM and SPMs, and test its usability and feasibility for implementation.
Methods
Based on a set of individualized interventions formulated in our preliminary work, we developed iCARE using mHealth techniques and a user-centred approach, which included 3 phases: (1) identifying patient preferences regarding formats for providing interventions; (2) designing the functions, architecture, and user interface (UI); (3) developing the iCARE using prototyping techniques. Usability test was conducted in patients with acute coronary syndromes and/or underwent percutaneous coronary intervention from January to March 2019 in two University affiliated hospitals in our city. The iCARE was implemented in 4 cardiac units of the same hospitals thereafter.
Results
The iCARE architecture and UI are displayed in Fig 1. Different from most current available mHealth CHD management system, the iCARE has a set of interventions and IF-THEN algorithms triggering interventions to ensure that patients receive individualized recommendations for UhLM and SPMs adherence. To improve effectiveness of iCARE interventions, visualization was used to augment patients' perceptions of risks of non-adherence to UhLM and SPMs, and effectiveness of adopting healthy lifestyles etc. Interventions are triggered by results of initial assessment and health data from daily monitoring. The initial assessment is conducted before patients are discharged, and a health report as well as individualized goals for risk reduction are formulated automatically. Daily diet, physical activities, smoking, medication adherence, blood pressure, blood sugar, and symptoms are monitored either through wearable devices or manual entry. Instant and individualized feedbacks as well as recommended actions are sent to patients automatically. A build-in artificial intelligent Q-A function was also included in iCARE. For the usability test, 88 patients with 71.3% male and mean age of 60 (SD 9.9) were recruited, 87.5% were satisfied with iCARE; 89.5% and 81.4% reported that iCARE was useful and easy to use, respectively. Currently, a total of 201 patients with 83.1% male and mean age of 54 (SD 10.2) were recruited from June 2019 to January 2020, and 46 of them have been followed up for 3 months.
Conclusions
The iCARE has achieved its functions of serving as an individualized and intelligent CHD management tool to improve adherence to UhLM and SPMs. The usability is satisfactory and it is feasible to implement in clinical settings.

ULTRASOUND IN MEDICINE & BIOLOGY 2020; 46:2683-2691. [PMID: 32709521 DOI: 10.1016/j.ultrasmedbio.2020.06.016] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 07/17/2019] [Revised: 06/19/2020] [Accepted: 06/23/2020] [Indexed: 06/11/2023]
Abstract
The objective of the study was to evaluate myocardial stiffness in hypertensive patients by measuring the intrinsic velocity propagation (IVP) of the myocardial stretch and to explore the correlation between IVP and cardiac systolic and diastolic functions. Eighty-one hypertensive patients and 53 healthy patients were prospectively enrolled in this study. IVP was measured using high-frame rate tissue Doppler (350-450 frames per second). IVP was significantly higher in hypertensive patients than in the control group (1.53 ± 0.39 m/s vs. 1.40 ± 0.19 m/s, p = 0.031). In the hypertensive group, IVP was significantly higher in patients with electrocardiogram (ECG) strain than in those without ECG strain (1.63 ± 0.46 m/s vs. 1.45 ± 0.32 m/s, p = 0.047). Moreover, IVP exhibited a good correlation with interventricular septal thickness at end-diastole (r = 0.434, p < 0.001), left ventricular posterior wall thickness at end-diastole (r = 0.439, p < 0.001), E/A ratio (r = 0.245, p = 0.004) and global longitudinal systolic strain (r = 0.405, p < 0.001). IVP was significantly higher in hypertensive patients, which indicates elevated myocardial stiffness in this cohort of patients. This novel measurement exhibited great potential for use in clinical practice to assess myocardial stiffness in patients with hypertension non-invasively.

Abstract
BACKGROUND Clinically, doctors obtain the left ventricular posterior wall thickness (LVPWT) mainly by observing ultrasonic echocardiographic video stream to capture a single frame of images with diagnostic significance, and then mark two key points on both sides of the posterior wall of the left ventricle with their own experience for computer measurement. In the actual measurement, the doctor's selection point is subjective, and difficult to accurately locate the edge, which will bring errors to the measurement results. METHODS In this paper, a convolutional neural network model of left ventricular posterior wall positioning was built under the TensorFlow framework, and the target region images were obtained after the positioning results were processed by non-local mean filtering and opening operation. Then the edge detection algorithm based on threshold segmentation is used. After the contour was extracted by adjusting the segmentation threshold through prior analysis and the OTSU algorithm, the design algorithm completed the computer selection point measurement of the thickness of the posterior wall of the left ventricle. RESULTS The proposed method can effectively extract the left ventricular posterior wall contour and measure its thickness. The experimental results show that the relative error between the measurement result and the hospital measurement value is less than 15%, which is less than 20% of the acceptable repeatability error in clinical practice. CONCLUSIONS Therefore, the measurement method proposed in this paper has the advantages of less manual intervention, and the processing method is reasonable and has practical value.

Abstract
AIM Many studies have demonstrated predictors of the difficulty of laparoscopic anterior resection for rectal cancer. Few studies focus on the influence of pelvic dimensions on robotic-assisted mesorectal excision (ME) and intersphincteric resection (ISR). This study aimed to evaluate the influences of the mesorectal fat area (MFA) and mesorectal area on the difficulty of robotic sphincter-saving surgery. METHODS We included 156 patients with middle and low rectal cancer who underwent robotic sphincter-saving surgery. Clinical and anatomical factors, including the pelvic dimensions, were collected. Linear regression was performed for variables associated with surgical duration. We also performed subgroup analyses for robotic-assisted ME and ISR. Logistic regression was used to find variables associated with transanal dissection. RESULTS For patients with middle or low rectal cancer, the sacral length and tumour distance from the anal verge were independently associated with surgical duration. The pT stage, sacral length and the MFA were independent predictors for the surgical duration of robotic-assisted ME. By contrast, a small mesorectal area was independently related to a longer duration of robotic-assisted ISR. The pelvic outlet length was independently associated with the use of transanal dissection for ISR. CONCLUSION It is suggested that a large MFA could affect the difficulty of ME in robotic-assisted ME, while a small mesorectal area could increase the surgical difficulty of robotic-assisted ISR for low rectal cancer. Besides, the pelvic outlet length was associated with the use of transanal dissection. Further studies are needed to validate the results and draw more scientific conclusions.

Abstract
OBJECTIVE To analyze the changes in the endemic situation of schistosomiasis in national surveillance sites of Hunan Province, so as to provide scientific basis for the development of the schistosomiasis elimination programme in the province. METHODS According to the requirements of the National Guidelines for Schistosomiasis Surveillance in China (2014 version), a total of 41 national schistosomiasis surveillance sites were assigned in all disease-endemic counties (districts) across Hunan Province. During the period between 2015 and 2019, Schistosoma japonicum infections were monitored in local residents, mobile populations and livestock, and snail status was monitored. The morbidity due to schistosomiasis and snail status was compared between years. RESULTS The sero-prevalence of S. japonicum infections was 2.57% and 1.56% in local residents and mobile populations in national surveillance sites of Hunan Province from 2015 to 2019, respectively, and the sero-prevalence appeared a tendency towards a decline over years. A higher sero-prevalence rate of S. japonicum infections was seen in men than in women (P < 0.01). During the 5-year study period, the sero-prevalence rate of human S. japonicum infections appeared a tendency towards a decline in the marshland, embankment, inner embankment and hilly types of endemic areas over years. There were 44 and 19 egg -positives detected in local residents and 5 and 1 egg-positives in mobile populations in 2015 and 2016 respectively. A total of 9 346 domestic animals were monitored from 2015 to 2019, and 6 egg-positives were detected in 2015 and 2016 (all were bovine). A total of 0.155 billion m2 settings were surveyed from 2015 to 2019, and the mean density of living snails appeared a tendency towards a decline over years, with a 45.79% reduction in 2019 as compared to 2015. However, no S. japonicum infections were identified in snails during the 5-year period. A total of 1 469 mixed snail samples were detected using loop-mediated isothermal amplification (LAMP), and 6 positive snail samples were identified in 2015 (one sample) and 2017 (5 samples). CONCLUSIONS The overall endemic situation of schistosomiasis appears a tendency towards a decline in Hunan Province, and the prevalence of S. japonicum infections is at a low level in humans and livestock; however, there is still a risk of schistosomiasis transmission. Improvements of health education, intensification of schistosomiasis examinations in mobile populations and reinforcement of the surveillance-response system is required to consolidate the achievements of schistosomiasis control in Hunan Province.

Abstract
AIMS To examine the association of HbA1c and glucose levels with incident diabetic retinopathy according to black African or white European ancestry. METHODS In this retrospective cohort study of 202 500 US Veterans with diabetes (2000-2014), measures included HbA1c , outpatient random serum/plasma glucose, and incident retinopathy [conversion from negative to ≥2 positive evaluations (ICD-9 codes), without a subsequent negative]. RESULTS At baseline, the study population had a mean age of 59.3 years, their mean BMI was 31.9 kg/m2 , HbA1c level was 57 mmol/mol (7.4%) and glucose level was 8.8 mmol/l, and 77% were of white European ancestry (white individuals) and 21% of black African ancestry (black individuals). HbA1c was 0.3% higher in black vs white individuals (P < 0.001), adjusting for baseline age, sex, BMI, estimated glomerular filtration rate (eGFR), haemoglobin, and average systolic blood pressure and glucose. Over 11 years, incident retinopathy occurred in 9% of black and 7% of white individuals, but black individuals had higher HbA1c , glucose, and systolic blood pressure (all P < 0.001); adjusted for these factors, incident retinopathy was reduced in black vs white individuals (P < 0.001). The population incidence of retinopathy (7%) was associated with higher mean baseline HbA1c in individuals with black vs white ancestry [63 mmol/mol (7.9%) vs 58 mmol/mol (7.5%); P < 0.001)], but with similar baseline glucose levels (9.0 vs 9.0 mmol/l; P = 0.660, all adjusted for baseline age, sex and BMI). CONCLUSIONS Since retinopathy occurs at higher HbA1c levels in black people for a given level of average plasma glucose, strategies may be needed to individualize the interpretation of HbA1c measurements.

Abstract
Abstract
Introduction
The study was to investigate trajectories of infant sleep duration and associations with trajectories of maternal depression status during 3 years post-partum.
Methods
Data were from the Child Health Promotion Project in Shanghai (CHPPS). Mothers were recruited at the third trimester of pregnancy and followed up together with the infants until 36 months postpartum. Between 2012 and 2013, 262 women (Mage=29.5, SDage=3.2, range: 22-39 years old) were recruited and were followed from June 2012 to August 2015. Sleep duration of the children was assessed using Brief Infant Sleep Questionnaire (BISQ) at 42 days, 3 months, 6 months, 9 months, 12 months, 18 months, 24 months, and 36 months postpartum. Center for Epidemiological Survey-Depression Scale (CESD), Edinburgh Postnatal Depression Scale (EPDS), and the Profile of Mood States (POMS) were used to measure the mother’s depression status at late pregnancy, 42 days postpartum, and 12-36 months postpartum, respectively. The group-based trajectory models (GBTM) were used to estimate patterns of infant sleep duration development and maternal depression status.
Results
Two trajectories of infant day sleep duration were identified, defined as “initial short sleepers” (54.8%) and “initial long sleepers” (45.2%). Three trajectories of infant night sleep duration were identified, labeled as “increasing” (8.5%), “stable” (61.7%), and “mild declining” (29.8%). Two trajectories infant total sleep duration were identified, defined as “initial short sleepers” (51.5%) and “initial long sleepers” (48.5%). Two trajectories of maternal depression status were identified, labeled as “low” (74.2%) and “high” (25.8%). After controlling for covariates, women who have higher depression status had infants of shorter day sleep duration. There was no significant association with infant night sleep duration.
Conclusion
Our study suggests that maternal postpartum depression is associated with short infant day sleep duration, but not with infant night sleep duration.

Abstract
Abstract
Introduction
Cross-sectional and longitudinal studies have consistently reported associations between sleep disturbances and emotional/behavioral problems in children. However, few studies have examined whether the remission, acquisition of sleep disturbances contribute to the transition of emotional and behavioral problems during preschool years.
Methods
This study used data from the Shanghai Children’s Health, Education and Lifestyle Evaluation-Preschool (SCHEDULEA-P), a prospective, population-based cohort study of newly enrolled preschoolers in Shanghai kindergartens in Nov. 2016. In total, 17182 children with complete data on parent-reported Strength and Difficulties Questionnaire (SDQ) both at school enrollment(wave 1) and the third year(wave 2) were included in the study. Children’s sleep disturbances were measured using Children Sleep Habit Questionnaire (CSHQ) at both waves.
Results
The 17182 participants included 8935(52.0%) males, with a mean (SD) age of 3.73(0.29) years at wave 1. 66.9%, 7.2%, 17.4% and 8.5% of these children were divided into persistent sleep disturbance, acquired, remitted group and persistent normal sleep group, respectively. The proportion of persistent, acquired, remitted emotional/behavioral problems and normal group was 13.7%, 9.4%, 21.1%, 55.8%. SDQ scores of acquired sleep disturbances group stayed high at wave 3, while SDQ scores of remitted sleep disturbances group decreased sharply during the preschool years. After adjusted for confounding factors, the odds of remission from emotional/behavioral problems among children who experienced remission of sleep disturbances, who had persistent normal sleep were both much higher compared to those who had persistent sleep disturbances (OR=2.53(2.12-3.01), p<0.001; OR=2.74(2.01-3.75), p<0.001). Meanwhile, the odds of acquisition of emotional/behavioral problems at wave 2 among subjects who newly acquired sleep disturbances at wave 2 and who had persistent sleep disturbances was similarly higher than those who never have sleep disturbances(OR= 2.75, P<0.001 VS OR=2.77, P<0.001). Besides, those who experience remission of sleep disturbances still have 1.48 times the odds of acquisition of emotional / behavioral problems(P=0.006).
Conclusion
The remission of sleep disturbances contributed to the remission of emotional/behavioral problems, while the emergence of sleep disturbances throughout preschool years increased the risk of the acquisition of emotional/behavioral problems.

Abstract
OBJECTIVE Glucose is not only an energy source but also raw material for proteoglycan biosynthesis of chondrocyte. The aim of the present study is to explore the role of QNZ in the progress of chondrocytes glucose uptake and investigate whether it will improve the chondrocytes degeneration through Glut4 activation. PATIENTS AND METHODS We isolated human chondrocytes from the cartilage by the patients who underwent total knee arthroplasty operations. Chondrocytes were pretreated with insulin or QNZ for 24 h. The uptake of glucose with stimulation, as well as the expression of Glut4, collagen II, aggrecan, MMP13, TNF-α, PCNA, and the p16 levels were determined by Western blot, quantitative reverse-transcription polymerase chain reaction (qPCR), or immunofluorescence. RESULTS Both insulin and QNZ stimuli to chondrocytes contributed to the expression of Glut4 and glucose uptake compared to the normal cells. Additionally, collagen II and aggrecan expression was detected to a significant increase, along with the reduced levels of MMP13 and TNF-α after exposed to QNZ. Moreover, QNZ protected chondrocytes degeneration via promoting proliferation and delaying aging. After blocking Glut4, the glucose uptake significantly reduced in QNZ treatment, as well as the expression of collagen II and aggrecan. However, no significant changes were noticed in the MMP13 and TNF-α levels. CONCLUSIONS The present study demonstrates that inhibition of NF-κB activation by QNZ would improve the glucose uptake through Glut4 activation, which plays an important role in the protection of chondrocytes degeneration.
