RESUMO
Objective: The purpose of the study was to describe the prevalence of myopia and to explore the associated factors of myopia among Han and Yi students aged 5-16 years in Yunnan province, China. Methods: A total of 5 971 Han and Yi students were included in the data analysis from the Yunnan eye study which was conducted from March to August, 2014. Information regarding demographic factors, socioeconomic status and lifestyle-related exposures were collected by per-designed questionnaires. The ophthalmic examinations including distance visual acuity, anterior segment examination, cycloplegic auto-refraction, and ocular motility examination were conducted. Logistic regression models were fitted to estimate the risk factors for myopia. Results: The age of 5 971 subjects was (10.68±2.24)years old, and the total prevalence of myopia and high myopia was 48.05% and 0.59%. Myopia prevalence was found to be higher in Han students compared with Yi ethnicity (50.20% vs. 47.10%,P=0.029). In multivariate analysis, the occurrence of myopia was associated with age (OR=1.28, 95%CI: 1.25-1.31), girls (OR=1.32, 95%CI: 1.18-1.48), increasing reading and writing time per day (OR=1.13, 95%CI: 1.07-1.20), having self-reported myopia among friend(s) (OR=1.15, 95%CI: 1.02-1.29), having myopic father (OR=1.38, 95%CI: 1.06-1.79), having myopic mother (OR=1.43, 95%CI: 1.12-1.83) and higher educated mother (OR=1.24, 95%CI: 1.03-1.51). Conclusions: We observed a high prevalence of myopia among Mangshi students. The presence of myopia was associated with increasing age, girls, increasing reading and writing time per day, having self-reported myopia among friend(s), having myopic father, having myopic and high educated mother.

OBJECTIVES: The aim of this study is to describe the prevalence and associated factors of spectacles need and ownership among multiethnic school students in rural China. STUDY DESIGN: School-based cross-sectional study. METHODS: This school-based eye study was conducted in Yunnan province located in Southwestern China. Questionnaires were filled out by children with the help of their parents concerning demographic characteristics, spectacles usage, and myopia-related lifestyle exposures. Spectacles need was defined as participants who had an uncorrected visual acuity (VA) of less than 6/12 but could be corrected to more than 6/12 in the better-seeing eye, with myopia of less than -0.5 diopters (D), hyperopia of more than +2.0 D, or astigmatism of more than 0.75 D in both eyes. Definition of spectacles ownership was based on spectacles wearing at school on the examination day. RESULTS: Among the 7681 students aged 5-16 years participating in this study, 7166 (93.3% of the study participants) successfully completed VA tests and questionnaires. The rate of spectacles need among children with an uncorrected VA of 6/12 or worse in either eye was 68.3% (623/912). Among the students who needed spectacles, only 18.9% owned them. Multivariate analyses revealed that spectacles ownership was significantly associated with increasing age (odds ratio [OR]: 1.30; 95% confidence interval [CI]: 1.08-1.55), more time on reading and writing (OR = 1.66; 95% CI: 1.15-2.40), having myopic friend(s) (OR: 1.90; 95% CI: 1.01-3.56), self-awareness of myopia (OR: 6.67; 95% CI: 2.48-17.92), and poorer uncorrected VA (OR: 4.57; 95% CI: 2.78-7.52). CONCLUSIONS: We observed a lower rate of spectacles ownership among rural children compared with those of similar ages in urban China. These findings may have important public health implications for China and other countries regarding vision-related health resources allocation.

Objective: Based on a cohort and intervention study of the Eastern Chinese Student Surveillance, Cohort and Intervention Study (ES-SCI), this research aims to explore the correlation between monitor of the school environment and longitudinal data on myopia and provide evidence for the government myopia intervention strategy. Methods: This survey adopts the stratified cluster sampling method with the school as the unit. Students from grade 1 to grade 3 were selected according to the whole class to monitor the school environment in the classroom. Students will use the full-automatic computer optometer (TOPCON RM800) to conduct optometry from 2019 to 2021 under the condition of mydriasis to perform refractive eye examinations. Meantime eye axis length monitoring was also conducted. Cox proportional risk regression model was used to explore the relationship between school environmental monitoring and the occurrence and development of students' myopia. Results: From 2019 to 2021, 2 670 students from 77 classrooms participated in the observation study. The students' diopter after right/left eye mydriasis decreased in varying degrees (P<0.001), and the axial length of the right/left eye increased in various degrees (P<0.001). The weighted qualified rate of per capita area of primary school classrooms increased from 18.0% in 2019 to 26.0% in 2021, the weighted average illuminance pass rate of blackboard surface increased from 23.8% in 2019 to 26.4% in 2021, and the weighted average illuminance pass rate of classroom table decreased from 86.7% in 2019 to 77.5% in 2021. The trend chi-square test was significant (P<0.05). Cox proportional risk regression showed that after correcting for the grade, gender, parental myopia, diet, sleep, near work (sitting posture, working time, electronic mobile equipment, eye exercises), and outdoor activities, the per capita area of 1.36- m2 was the protective factor of eye axis length (HR=0.778, 95%CI: 0.659-0.918, P=0.003); The average reflection ratio of blackboard 0.15-0.19 was the protective factor of eye axis length (HR=0.685, 95%CI: 0.592-0.793, P<0.001); The average illumination of the blackboard 150-, 300-, 500- lx was the protective factor of the eye axis length (HR=0.456, 95%CI: 0.534-0.761, P<0.001; HR=0.794, 95%CI: 0.705-0.895, P<0.001; HR=0.690, 95%CI: 0.619-0.768, P<0.001). The blackboard evenness 0.40-0.59 was the risk factor of eye axis length (HR=1.528, 95%CI: 1.018-2.293, P=0.041), and the blackboard evenness 0.80- was the protection factor of eye axis length (HR=0.542, 95%CI: 0.404-0.726, P<0.001). The evenness of the desktop 0.40-0.59 was the protective factor of eye axis length (HR=0.820, 95%CI: 0.698-0.965, P=0.017). The average illuminance of 150-, 300-, 500- lx was the protective factor of a diopter (HR=0.638, 95%CI: 0.534-0.761, P<0.001; HR=0.911, 95%CI: 0.848-0.978, P=0.011; HR=0.750, 95%CI: 0.702-0.801, P<0.001). The average illumination of desktop 500- lx was a protective factor of a diopter (HR=0.855, 95%CI: 0.763-0.958, P=0.007). Conclusion: School environmental monitoring indicators, such as meeting per capita area standards, passing blackboard, and desk top-related indicators, all play protective effects on myopia development in students.

We report a neonate with pure deletion of distal 11q (11q23.3-->qter) and Jacobsen syndrome. The patient had growth restriction, petechiae, thrombocytopenia, dilation of renal pelvis, congenital heart defects, and seizures. Array comparative genomic hybridization revealed a 15.8-Mb deletion from 11q23.3 to 11q25 without genomic imbalances in other chromosomes. Cytogenetic analysis revealed a karyotype of 46,XX,der(7)(7pter-->7q32),der(11)(11pter--> 11q23.3::7q32-->7qter). The parental karyotypes were normal. This is the first report of pure distal 11q deletion without additional genomic imbalances in a patient with Jacobsen syndrome and a de novo unbalanced reciprocal translocation.

Intracranial aneurysms with subarachnoid hemorrhage lead to high morbidity and mortality. It is of critical importance to detect aneurysms, identify risk factors of rupture, and predict treatment response of aneurysms to guide clinical interventions. Artificial intelligence has received worldwide attention for its impressive performance in image-based tasks. Artificial intelligence serves as an adjunct to physicians in a series of clinical settings, which substantially improves diagnostic accuracy while reducing physicians' workload. Computer-assisted diagnosis systems of aneurysms based on MRA and CTA using deep learning have been evaluated, and excellent performances have been reported. Artificial intelligence has also been used in automated morphologic calculation, rupture risk stratification, and outcomes prediction with the implementation of machine learning methods, which have exhibited incremental value. This review summarizes current advances of artificial intelligence in the management of aneurysms, including detection and prediction. The challenges and future directions of clinical implementations of artificial intelligence are briefly discussed.

Simulation systems have become essential to the development and validation of autonomous driving (AD) technologies. The prevailing state-of-the-art approach for simulation uses game engines or high-fidelity computer graphics (CG) models to create driving scenarios. However, creating CG models and vehicle movements (the assets for simulation) remain manual tasks that can be costly and time consuming. In addition, CG images still lack the richness and authenticity of real-world images, and using CG images for training leads to degraded performance. Here, we present our augmented autonomous driving simulation (AADS). Our formulation augmented real-world pictures with a simulated traffic flow to create photorealistic simulation images and renderings. More specifically, we used LiDAR and cameras to scan street scenes. From the acquired trajectory data, we generated plausible traffic flows for cars and pedestrians and composed them into the background. The composite images could be resynthesized with different viewpoints and sensor models (camera or LiDAR). The resulting images are photorealistic, fully annotated, and ready for training and testing of AD systems from perception to planning. We explain our system design and validate our algorithms with a number of AD tasks from detection to segmentation and predictions. Compared with traditional approaches, our method offers scalability and realism. Scalability is particularly important for AD simulations, and we believe that real-world complexity and diversity cannot be realistically captured in a virtual environment. Our augmented approach combines the flexibility of a virtual environment (e.g., vehicle movements) with the richness of the real world to allow effective simulation.
RESUMO
BACKGROUND: Although tea consumption has been reported to have various health benefits in humans, its association with health-related quality of life (HRQOL) has not been investigated directly. We aimed to examine the relationship between tea consumption and HRQOL among older Chinese adults. METHODS: We analyzed community-based cross-sectional data of 5,557 older Chinese individuals aged 60 years or older who participated in the Weitang Geriatric Diseases study. Information on tea consumption and HRQOL assessed by the European Quality of Life-5 dimensions (EQ-5D) were collected by questionnaires. We estimated the relationship of tea consumption and the EQ-5D index score using linear regression models and the association between tea consumption and self-reported EQ-5D health problems using logistic regression models. RESULTS: The EQ-5D index score was higher for habitual tea drinkers than their counterparts. In multivariate linear analyses controlling for socio-demographic conditions, health conditions, and lifestyle habits, the differences in ED-5D index score between individuals with and without tea drinking habits was 0.012 (95% confidence interval, 0.006-0.017). In multivariate logistic analyses, habitual tea drinking was inversely associated with reporting of problems in EQ-5D dimensions mobility (odds ration [OR], 0.44; 95% CI: 0.23-0.84); pain/discomfort (OR, 0.74; 95% CI: 0.61-0.90); and anxiety/depression (OR, 0.60; 95% CI: 0.38-0.97). These associations were more evident for black or oolong tea than green tea. CONCLUSION: Habitual tea consumption was associated with better HRQOL in older adults.

OBJECTIVES: Tea has long been hypothesized to possess hypotensive effects. However, there is uncertainty regarding the association of tea consumption with arterial blood pressure (BP). We aimed to examine the association between tea consumption and BP components including systolic BP (SBP) and diastolic BP (DBP). DESIGN: Community-based, cross-sectional study of Suzhou City, Jiangsu Province, China. SETTING: Tea consumption has protective influence on BP and presence of hypertension. PARTICIPANTS: 4579 older adults aged 60 years or older from the Weitang Geriatric Diseases study. MEASUREMENTS: Detailed information regarding tea consumption was collected using a pre-designed questionnaire. BP components were measured at least 3 times with a minimum 5-minute interval, by well-trained research nurses. METHODS: Data of 4579 older adults (response rate: 82%) aged 60 years or older from the Weitang Geriatric Diseases study were included in the analysis and we estimated the relationship of tea consumption and BP using linear regression models and the association between tea consumption and risk of hypertension using logistic regression models. RESULTS: In linear regression models, higher tea consumption frequency was found to be associated with lower systolic BP values, after adjusting for the effect of age, sex, education level, lifestyle-related factors, and cardiometabolic confounding factors in overall (coefficient =-1.49, P=0.0003), normotensive (coefficient =-0.91, P=0.017) and participants without anti-hypertensive treatment (coefficient =-1.26, P=0.027). Significant inverse association between diastolic BP and frequency of tea consumption was also observed in the overall subjects (coefficient =-0.74, P=0.003). In multivariate logistic analyses, habitual tea drinking was inversely associated with presence of hypertension [odds ratio (OR)=0.79, P=0.011] , and there was a progressive reduction in risk associated with higher frequency of tea consumption (P for trend=0.011). CONCLUSION: Habitual tea consumption was found to be associated with lower values of components of BP and a reduced likelihood of having hypertension in older adults. Given the widespread consumption of tea throughout China and the world, together with the major cardiovascular disease risk, our findings have important implications for human health.

OBJECTIVE: To investigate the significance of the combined treatment with ganciclovir and interferon for patients with hepatitis C (HCV) liver fibrosis. PATIENTS AND METHODS: We retrospectively summarize 86 patients with hepatitis C treated in our hospital from October 2013 to October 2015. 49 cases, considered as control group, received combined treatment with α-interferon and ribavirin; 37 cases, considered as observation group, received combined treatment with ganciclovir and interferon. The changes of liver fibrosis, viral replication and liver function of both groups were compared for two weeks and six months. RESULTS: The levels of sera hyaluronic acid (HA), laminin (LN), type IV collagen (IVC) and type III procollagen (PIII NP) of both groups were reduced after treatment, and the observation group improved more significantly (p <0.05). Compared to the rate of antigen-positive after treatment and HCV copy number before and after treatment, the differences were not statistically significant (p > 0.05). The level of alanine aminotransferase (ALT) of the control group increased after treatment, compared with that before. This was done along with the decrease of the level of albumin. By contrast, the level of ALT in the observation group was reduced and the level of albumin was increased compared with that before (p < 0.05). CONCLUSIONS: Ganciclovir combined with interferon may further reduce the fibrosis process of patients with hepatitis C, and may improve liver function. The effect of antiviral was similar as ganciclovir combined with Interferon was comparatively good applied, safety and effectiveness.

Twelve patients (5 male and 7 female; mean age 17.7 +/- 12.3 years, range 5 to 42) with Marfan's syndrome and 48 of their first degree relatives (16 male and 22 female; mean age 29.8 +/- 17.3 years, range 4 to 60) were evaluated for cardiac abnormalities by echocardiography. Of the patients with Marfan's syndrome, aortic valve prolapse was present in 1, tricuspid valve prolapse in 4, mitral valve prolapse in 12 and aortic root dilation in 10. Of the 48 first degree relatives of these 12 patients, tricuspid valve prolapse was diagnosed in 3, mitral valve prolapse in 15 and aortic root dilation in 12; aortic valve prolapse was not observed in any of these subjects. Of the 60 persons studied in these 12 kindreds, 28 (47%) had cardiac involvement. Among the 28 with cardiac involvement, aortic valve prolapse was observed in 1 (3.5%), tricuspid valve prolapse in 7 (25%), mitral valve prolapse in 27 (96%) and aortic root dilation in 22 (79%). Mitral valve prolapse was also present in the seven subjects with tricuspid valve prolapse and one with aortic valve prolapse. In 32 of the 60 persons studied in the 12 families, at least one abnormality of the cardiac, skeletal or ophthalmologic system was observed. Nineteen subjects were younger than 18 years of age; all had cardiac involvement associated with Marfan's syndrome. The notably earlier presentation of cardiac involvement in young persons may be responsible for a shorter life span in this group.(ABSTRACT TRUNCATED AT 250 WORDS)

In an attempt to investigate the harmful effects of the infection of Toxoplasma and associated with cytomegalovirus on the fetus infection acquired transplacentally during their mothers' pregnancy sera from 1000 pregnant women were tested for antibodies to both pathogens and the circulating antigen of Toxoplasma by using ELISA. The test was positive (titre > or = 1:60400) in 32 of 1000 cases. Judging from the sero-positive results together with the case history, clinical manifestations and B-scan results, the 32 cases were advised to end their pregnancy. Necropsy and pathological examinations of the foetuses revealed stillborn foetus, hydrocephalus, acephalus, pleural effusion, ascites and other congenital malformations. Toxoplasma gondii were found in the tissues of 21 fetuses.

OBJECTIVE: To find out the cause and transmission factors of an outbreak of eosinophilic meningoradiculitis in Wenzhou City during October to November in 1997. METHODS: In addition to a retrospective cohort study on 182 persons who had dined at a same restaurant of the city, etiological and immunoserological investigations were conducted. RESULTS: Among 105 cases who had eaten the undercooked Ampullaria gigas in that restaurant, 47 cases were infected, the incidence rate was 44.8%; whereas none of the persons who did not eat the under-cooked Ampullaria gigas in that restaurant got the infection, the difference between the two groups being significant(P < 0.001). The incidence rate of the cases who had eaten 4 and more pieces of the undercooked Ampullaria gigas was 86.2%(25/29), while that of those who had eaten less than 4 pieces was 28.9%(22/76), the difference between the two being very significant (chi 2 = 27.83, P < 0.001, RR = 2.98). The third stage larvae of the Angiostrongylus cantonensis were found out from Ampullaria gigas living in the same locality, and the adult worms of Angiostrongylus contonensis were found out from the rats living in the locality else. The positive rate of serum anti-Angiostrongylus cantonensis antibody in the patients was 84.0%. CONCLUSION: On the basis of the clinical, epidemiological, immunoserological and etiological investigations, an outbreak of the angiostrongyliasis cantonensis caused by eating undercooked Ampullaria gigas was confirmed.

We describe perinatal findings in a female fetus with partial trisomy 8q(8q24.1-->8qter) and partial monosomy 15q(15q26.1-->15qter) resulting from a paternal t(8;15) reciprocal translocation. Prenatal sonographic examination showed intra-uterine growth retardation, bilateral ventriculomegaly, cardiomegaly with arrhythmia, anhydramnios, and absent kidney and urinary bladder images. The pregnancy was terminated at 28 weeks of gestation. At birth, the infant manifested typical dysmorphic features of partial trisomy 8q. Necropsy further revealed hydrocephalus, congenital diaphragmatic hernia, ventricular septal defect, a horseshoe kidney with renal hypoplasia, and kyphoscoliosis. Our case shows that the coexistence of partial trisomy 8q24.1-->8qter and partial monosomy 15q26.1-->15qter are more detrimental than either defect alone and can result in a complex of major malformations. Prenatal ultrasound examination and cytogenetic assessment should be offered in subsequent pregnancies.

In utero diagnosis of de novo distal 11q deletion associated with renal and orofacial malformations has not been previously described. We present a 35-year-old pregnant woman with prenatal sonographic findings of a unilateral duplex renal system, pyelectasis and orofacial clefts at 20 weeks' gestation. Both genetic amniocentesis and postnatal cytogenetic analysis revealed de novo 46,XX,del(11)(q23). After birth, the fetus manifested a dysmorphic phenotype correlated with del(11q) syndrome. Genetic marker analysis showed a paternally derived distal deletion of chromosome 11q and a breakpoint centromeric to D11S1341. The present case represents the earliest prenatal diagnosis of a duplex renal system, pyelectasis and an additional feature of orofacial clefts associated with distal 11q deletion. Prenatal sonographic detection of a duplex renal system, pyelectasis and orofacial clefts should warrant a careful assessment of fetal anatomy and prompt cytogenetic analysis looking for chromosomal aberrations.
