RESUMEN
TRPM3 belongs to the melastatin sub-family of transient receptor potential (TRPM) cation channels and has been shown to function as a steroid-activated, heat-sensitive calcium ion (Ca2+) channel. A missense substitution (p.I65M) in the TRPM3 gene of humans (TRPM3) and mice (Trpm3) has been shown to underlie an inherited form of early-onset, progressive cataract. Here, we model the pathogenetic effects of this cataract-causing mutation using 'knock-in' mutant mice and human cell lines. Trpm3 and its intron-hosted micro-RNA gene (Mir204) were strongly co-expressed in the lens epithelium and other non-pigmented and pigmented ocular epithelia. Homozygous Trpm3-mutant lenses displayed elevated cytosolic Ca2+ levels and an imbalance of sodium (Na+) and potassium (K+) ions coupled with increased water content. Homozygous TRPM3-mutant human lens epithelial (HLE-B3) cell lines and Trpm3-mutant lenses exhibited increased levels of phosphorylated mitogen-activated protein kinase 1/extracellular signal-regulated kinase 2 (MAPK1/ERK2/p42) and MAPK3/ERK1/p44. Mutant TRPM3-M65 channels displayed an increased sensitivity to external Ca2+ concentration and an altered dose response to pregnenolone sulfate (PS) activation. Trpm3-mutant lenses shared the downregulation of genes involved in insulin/peptide secretion and the upregulation of genes involved in Ca2+ dynamics. By contrast, Trpm3-deficient lenses did not replicate the pathophysiological changes observed in Trpm3-mutant lenses. Collectively, our data suggest that a cataract-causing substitution in the TRPM3 cation channel elicits a deleterious gain-of-function rather than a loss-of-function mechanism in the lens.

BACKGROUND: Corneal pregnancy is rare and difficult to detect in the early stages. Due to the abundant blood supply in this area, a rupture can result in massive internal bleeding, shock, and even death. Therefore, immediate surgery is necessary, and patients must replenish their blood volume as soon as possible to ensure blood supply to important organs. For those whose blood pressure cannot immediately rise, surgery should be performed while resisting shock to buy time. CASE SUMMARY: We present the case of a 34-year-old Chinese woman at 19 weeks of gestation who had a corneal pregnancy. No abnormalities were detected in the examinations in the first trimester. This patient was 19 weeks pregnant and sought medical advice due to sudden lower abdominal pain, syncope, and hemorrhagic shock. After rescue and treatment, she recovered and was discharged from the hospital, afterwards, the patient gave birth to a child 7 years later. CONCLUSION: The early diagnosis of cornual pregnancy is mainly based on ultrasound. However, there is a high incidence of missed diagnosis and misdiagnosis of this disease. Patients may face serious and life-threatening conditions in case of the rupture of cornual pregnancy. This disease can be mainly treated by surgery.

The Emory cataract (Em) mouse mutant has long been proposed as an animal model for age-related or senile cataract in humans-a leading cause of visual impairment. However, the genetic defect(s) underlying the autosomal dominant Em phenotype remains elusive. Here, we confirmed development of the cataract phenotype in commercially available Em/J mice [but not ancestral Carworth Farms White (CFW) mice] at 6-8 months of age and undertook whole-exome sequencing of candidate genes for Em. Analysis of coding and splice-site variants did not identify any disease-causing/associated mutations in over 450 genes known to underlie inherited and age-related forms of cataract and other lens disorders in humans and mice, including genes for lens crystallins, membrane/cytoskeleton proteins, DNA/RNA-binding proteins, and those associated with syndromic/systemic forms of cataract. However, we identified three cataract/lens-associated genes each with one novel homozygous variant including predicted missense substitutions in Prx (p.R167C) and Adamts10 (p.P761L) and a disruptive in-frame deletion variant (predicted missense) in Abhd12 (p.L30_A32delinsS) that were absent in CFW and over 35 other mouse strains. In silico analysis predicted that the missense substitutions in Prx and Adamts10 were borderline neutral/damaging and neutral, respectively, at the protein function level, whereas, that in Abhd12 was functionally damaging. Both the human counterparts of Adamts10 and Abhd12 are clinically associated with syndromic forms of cataract known as Weil-Marchesani syndrome 1 and polyneuropathy, hearing loss, ataxia, retinitis pigmentosa, and cataract syndrome, respectively. Overall, while we cannot exclude Prx and Adamts10, our data suggest that Abhd12 is a promising candidate gene for cataract in the Em/J mouse.

Charged multivesicular body protein 4b (CHMP4B) is a core sub-unit of the endosomal sorting complex required for transport III (ESCRT-III) machinery that serves myriad remodeling and scission processes of biological membranes. Mutation of the human CHMP4B gene underlies rare forms of early-onset lens opacities or cataracts, and CHMP4B is required for lens growth and differentiation in mice. Here, we determine the sub-cellular distribution of CHMP4B in the lens and uncover a novel association with gap junction alpha-3 protein (GJA3) or connexin 46 (Cx46) and GJA8 or Cx50. Immunofluorescence confocal microscopy revealed that CHMP4B localized to cell membranes of elongated fiber cells in the outer cortex of the lens-where large gap junction plaques begin to form-particularly, on the broad faces of these flattened hexagon-like cells in cross-section. Dual immunofluorescence imaging showed that CHMP4B co-localized with gap junction plaques containing Cx46 and/or Cx50. When combined with the in situ proximity ligation assay, immunofluorescence confocal imaging indicated that CHMP4B lay in close physical proximity to Cx46 and Cx50. In Cx46-knockout (Cx46-KO) lenses, CHMP4B-membrane distribution was similar to that of wild-type, whereas, in Cx50-KO lenses, CHMP4B localization to fiber cell membranes was lost. Immunoprecipitation and immunoblotting analyses revealed that CHMP4B formed complexes with Cx46 and Cx50 in vitro. Collectively, our data suggest that CHMP4B forms plasma membrane complexes, either directly and/or indirectly, with gap junction proteins Cx46 and Cx50 that are often associated with "ball-and-socket" double-membrane junctions during lens fiber cell differentiation.

Background: Robots are increasingly used as interaction partners with humans. Social robots are designed to follow expected behavioral norms when engaging with humans and are available with different voices and even accents. Some studies suggest that people prefer robots to speak in the user's dialect, while others indicate a preference for different dialects. Methods: Our study examined the impact of the Berlin dialect on perceived trustworthiness and competence of a robot. One hundred and twenty German native speakers (M age = 32 years, SD = 12 years) watched an online video featuring a NAO robot speaking either in the Berlin dialect or standard German and assessed its trustworthiness and competence. Results: We found a positive relationship between participants' self-reported Berlin dialect proficiency and trustworthiness in the dialect-speaking robot. Only when controlled for demographic factors, there was a positive association between participants' dialect proficiency, dialect performance and their assessment of robot's competence for the standard German-speaking robot. Participants' age, gender, length of residency in Berlin, and device used to respond also influenced assessments. Finally, the robot's competence positively predicted its trustworthiness. Discussion: Our results inform the design of social robots and emphasize the importance of device control in online experiments.
RESUMEN
Objective@#To investigate incidence of traffic injury and its associated factors among secondary school students in Shanghai, so as to provide scientific basis for intervention.@*Methods@#Using the method of multi stage stratified random cluster sampling, an on-the-spot anonymous questionnaire survey was conducted among 19 629 adolescents from 16 districts in Shanghai from May to June 2021. The multivariate Logistic regression was used to analyze possible associated factors.@*Results@#The rate of road traffic injuries among secondary school students in Shanghai was 0.74%, the highest reporting rate among secondary vocational school students (1.35%), followed by junior high school students (0.72%), and the lowest reporting rate of road traffic injuries among senior high school students (0.55%), with statistically significant differences ( χ 2=13.39, P <0.01). The results of multivariate Logistic regression analysis showed that the junior high school ( OR =0.56, 95% CI =0.35-0.89) or senior high school ( OR = 0.40 , 95% CI =0.24-0.68) and residential school ( OR =0.39, 95% CI =0.18-0.88) were protective factors of road traffic injuries( P <0.05). Male ( OR =1.65, 95% CI =1.14-2.37), unaware of seat belt ( OR =6.38, 95% CI =2.81-14.50), had a cycling chase/fight ( OR =2.33, 95% CI =1.39-3.90), music or phone calls on a bicycle ( OR =2.54, 95% CI =1.72-3.75) were positively correlated with road traffic injury( P <0.05).@*Conclusions@#The road traffic injury among secondary school students in Shanghai is related to many factors, and traffic hazards are common among students in all school sections. Targeted measures should be taken to strengthen traffic safety knowledge education and intervention in healthy behaviors among adolescents, in order to reduce the incidence of road traffic injury.
RESUMEN
Importance: Acupoint hot compress during the early postpartum period may benefit patients after a vaginal delivery, but the evidence of this effect is limited. Objective: To assess whether acupoint hot compress involving the abdominal, lumbosacral, and plantar regions could reduce the incidence of postpartum urinary retention, relieve postpartum uterine contraction pain, prevent emotional disorders, and promote lactation. Design, Setting, and Participants: This multicenter randomized clinical trial was conducted at 12 hospitals in China. Pregnant patients were screened for eligibility (n = 13â¯949) and enrolled after vaginal delivery (n = 1200) between January 17 and August 15, 2021; data collection was completed on August 18, 2021. After vaginal delivery, these participants were randomized 1:1 to either the intervention group or control group. Statistical analysis was based on per-protocol population. Interventions: Participants in the control group received routine postpartum care. Participants in the intervention group received routine postpartum care plus 3 sessions of a 4-hour acupoint hot compress involving the abdominal, lumbosacral, and plantar regions within 30 minutes, 24 hours, and 48 hours after delivery. Main Outcomes and Measures: The primary outcome was the incidence of postpartum urinary retention, defined as the first urination occurring more than 6.5 hours after delivery and/or use of an indwelling catheter within 72 hours after delivery. The secondary outcomes were postpartum uterine contraction pain intensity (assessed with the visual analog scale [VAS]), depressive symptoms (assessed with the Edinburgh Postnatal Depression Scale), and lactation conditions (including lactation initiation time, breastfeeding milk volume, feeding mood and times, and newborn weight). Results: Of the 1200 participants randomized, 1085 completed the study (537 in the intervention group and 548 in the control group, with a median [IQR] age of 26.0 [24.0-29.0] years). Participants in the intervention group compared with the control group had significantly decreased incidence of postpartum urinary retention (relative risk [RR], 0.58; 95% CI, 0.35-0.98; P = .03); improved postpartum uterine contraction pain when measured at 6.5 hours (median [IQR] VAS score, 1 [1-2] vs 2 [1-2]; P < .001), 28.5 hours (median [IQR] VAS score, 1 [0-1] vs 1 [1-2]; P < .001), 52.5 hours (median [IQR] VAS score, 1 [0-1] vs 1 [0-1]; P < .001), and 76.5 hours (median [IQR] VAS score, 0 [0-1] vs 0 [0-1]; P = .01) after delivery; reduced depressive symptoms (RR, 0.73; 95% CI, 0.54-0.98; P = .01); and increased breastfeeding milk volume measured at 28.5, 52.5, and 76.5 hours after delivery. No adverse events occurred in either of the 2 groups. Conclusions and Relevance: Results of this trial showed that acupoint hot compress after vaginal delivery decreased postpartum urinary retention, uterine contraction pain, and depressive symptoms and increased breastfeeding milk volume. Acupoint hot compress may be considered as an adjunctive intervention in postnatal care that meets patient self-care needs.

BACKGROUND: Since December 2019, the coronavirus disease 2019 (COVID-19) has become a global pandemic. Currently, the COVID-19 pandemic is still ongoing. What changes have taken place in the obesity and obesity-related lifestyle behaviours of adolescents during the first year of the COVID-19 pandemic? OBJECTIVE: This study aims at analysing the changes in obesity and lifestyle behaviours of Chinese adolescents before and 1 year after the outbreak of the COVID-19 pandemic, providing evidence for the global strategies to respond to the impact of the COVID-19 pandemic on adolescent obesity. METHODS: Physical examinations and student health and influencing factors questionnaires were conducted among 6047 adolescents aged 11-16 years by health professionals in Shanghai, China, before the COVID-19 pandemic (September-November of 2019) and 1 year after the outbreak of the COVID-19 pandemic (September-November of 2020). Paired χ2 tests, paired t-tests or Wilcoxon signed-rank test was used to evaluate the changes in the obesity prevalence, BMI and lifestyle behaviours from 2019 to 2020. RESULTS: 1 year after the outbreak of the COVID-19 pandemic, the obesity prevalence of Chinese adolescents rose from 14.2% to 15.4% (p < 0.01), mainly because of the increase in boys. And the average BMI increased from 20.3 to 21.2 kg/m2 (p < 0.01). Their lifestyle behaviours have also significantly changed. The mobile screen time increased from 0.25-1.50 h/day to 0.33-2.00 h/day (p < 0.01). The proportion of adolescents who participated in MVPA for ≥60 min/day on all 7 days during the past week dropped from 14.4% to 11.7% (p < 0.01). The generalized estimation equation analysis indicated that adolescents who participated in MVPA for ≥60 min/day on all 7 days had a lower likelihood of having obesity. Boys with computer time ≥2 h/day and girls with mobile screen time ≥2 h/day or TV time ≥2 h/day had a higher likelihood of having obesity. CONCLUSION: This study found that 1 year after the outbreak of the COVID-19 pandemic, the BMI and obesity prevalence of Chinese adolescents increased and obesity-related lifestyle behaviours have also changed.

Objective@#To explore the relationship between myopia and nutritional status among upper elementary students in Shanghai.@*Methods@#A stratified cluster sampling method was used to select 5 576 fourth and fifth grade students from 16 districts in Shanghai, vision test, physical examination and questionnaire survey were administered. Two level multivariate Logistic regression and mixed linear models were used to analyze the relationship between myopia, spherical equivalent (SE) and nutritional status.@*Results@#The detection rates of overweight and obesity were 17.0%(949) and 18.7%(1 042), respectively. There was a statistical difference in the proportion of the nutritional status in boys and girls( χ 2=210.94, P <0.01), with overweight and obesity in boys higher than those of girls. The overweight boys were more likely to have myopia (univariate analysis: OR=1.23, P =0.04; multivariate analysis: OR=1.21, P =0.06) than the normal weight boy. Overweight students tended to had more negative refractive than those with normal weight in both boys and girls(multivariate analysis, boys: β =-0.19, girls: β=-0.24, P <0.05). Myopia risk and refractive power in obese students showed no statistical difference with normal weight students( P >0.05).@*Conclusion@#Overweight students have lower SE than the normal weight among upper elementary students of Shanghai, more researches are needed to confirm this finding and to provide theoretical bases for myopia prevention and control.
RESUMEN
Objective@#To investigate the establishment of health care institutions and the staffing primary and secondary school health care in Shanghai, and to understand the capacity building needs of health care personnel.@*Methods@#A survey was conducted on all primary and secondary schools in Shanghai from April to August in 2020. The content of the questionnaire covers the establishment of health care institutions, the staffing of school health care centers and the capacity building need of health care personnel. Chi square test was used to compare the difference of the health care institutions setting and staffing by schools and areas.@*Results@#In 2020, there were 1 847 primary and secondary schools in Shanghai (including branches schools). About 51.4% of primary and secondary schools in Shanghai were equipped with school health care personnel in the ratio of the number of students at least 600∶1 , and the staffing compliance rate of urban schools (59.3%) was higher than that of suburban schools (47.3%)( χ 2=24.27, P <0.01). All school health care personnel believed that there are currently few opportunities for capacity buliding services from health facilities.@*Conclusion@#School health care institutions in Shanghai are well equipped, but the staffing shortage is substantial, with strong need for capacity building.
RESUMEN
Objective@#To establish a risk assessment index system for epidemic infectious diseases in primary and secondary schools, for early warning and prevention of school infectious diseases accurately and timely.@*Methods@#Through literature review, the indicators pool was established by consulting relevant experts and referring to practical experience. Then two rounds of expert consultation using the Delphi method were conducted(13 experts of round 1, and 20 experts of round 2). The concentration of expert opinions (the average, the percentage of full marks) and the coordination of expert opinions (the coefficient of variation, the coordination coefficient W ) were calculated and analyzed. The coordination coefficient W was obtained by nonparametric Kendall s W test of multiple samples. According to the experts feedback, necessary addition, reduction and modification of the indicators were carried out to determine the evaluation index system, and the analytic hierarchy process (AHP) was used to calculate the weight of each indicator.@*Results@#The expert authority coefficients of the two rounds of consultation were 0.89 and 0.88, respectively, and the form recovery rate was 100%. The range of the variation coefficient of each three level indicator was 0.07-0.31 and 0.06-0.19, and the coordination coefficient W was 0.25 and 0.47, respectively, indicating that the consistency and credibility of expert opinions were good. Finally, the risk assessment index system of infectious diseases in primary and secondary schools was established, which was composed of 5 first level indexes, 23 second level indexes and 86 third level indexes. The AHP was used to calculate the intra level weight of the index. The variation coefficient of five first level indicators of school health management and security system, school health personnel facilities, health monitoring and cognition level, severity and coping measures were 0.09, 0.06, 0.08, 0.12 and 0.06 , respectively, and the weight coefficients were 20.42%, 21.19%, 19.87%, 17.45% and 21.08%, respectively.@*Conclusion@#The risk assessment index system of school infectious diseases is applicable to primary and secondary schools. The initiative, coordination and authority of experts in this system are all high. It is of practical guiding significance for the early warning of infectious diseases in primary and secondary schools.
RESUMEN
Genetic variations in ephrin type-A receptor 2 (EPHA2) have been associated with inherited and age-related forms of cataract in humans. Here, we have characterized the eye lens phenotype and transcript profile of germline Epha2 knock-in mutant mice homozygous for either a missense variant associated with age-related cataract in humans (Epha2-Q722) or a novel insertion-deletion mutation (Epha2-indel722) that were both located within the tyrosine-kinase domain of EPHA2. Confocal imaging of ex vivo lenses from Epha2-indel722 mice on a fluorescent reporter background revealed misalignment of epithelial-to-fiber cell meridional-rows at the lens equator and severe disturbance of Y-suture formation at the lens poles, whereas Epha2-Q722 lenses displayed mild disturbance of posterior sutures. Immunofluorescent labeling showed that EPHA2 was localized to radial columns of hexagonal fiber cell membranes in Epha2-Q722 lenses, whereas Epha2-indel722 lenses displayed disorganized radial cell columns and cytoplasmic retention of EPHA2. Immunoprecipitation/blotting studies indicated that EPHA2 formed strong complexes with Src kinase and was mostly serine phosphorylated in the lens. RNA sequencing analysis revealed differential expression of several cytoskeleton-associated genes in Epha2-mutant and Epha2-null lenses including shared downregulation of Lgsn and Clic5. Collectively, our data suggest that mutations within the tyrosine-kinase domain of EPHA2 result in lens cell patterning defects and dysregulated expression of several cytoskeleton-associated proteins.

BACKGROUND: Primary hyperparathyroidism (PHPT) in pregnancy has a negative impact. Effective treatment should be timely adopted. METHODS: We report a case of a 24-year-old pregnant woman admitted with PHPT, hypercalcemia crisis, hypokalemia, thyroid nodules, hyperthyroidism, and intrauterine single live fetus in the 2nd trimester of pregnancy. Right parathyroidectomy and partial thyroidectomy were timely performed. Postoperative pathology suggested parathyroid adenoma with capsule invasion and thyroid nodules. RESULTS: Postoperative serum PTH and Ca2+ were effectively reduced. Eventually, a healthy fetus was delivered via cesarean at full term. CONCLUSIONS: Parathyroidectomy within reasonable operative timing can improve maternal and fetal prognosis in PHPT during pregnancy, especially with concomitant hypercalcemia crisis.

BACKGROUND: We aimed to explore the influence of midwifery care on the mode of delivery (MOD), duration of labor and postpartum hemorrhage (PPH) of elderly parturients. METHODS: A total of 165 elderly parturients admitted to Tongde Hospital of Zhejiang Province, China from May 2018 to Aug 2019 were allocated into a study group (n=85, midwifery care) and a control group (n=80, conventional nursing care). Visual analogue scale (VAS) was employed to estimate the pain of parturients, and self-rating anxiety scale (SAS) and self-rating depression scale (SDS) were employed to evaluate the anxiety and depression status. The satisfaction of patients on nursing care was scored by a self-made satisfaction questionnaire. RESULTS: The parturients in the study group presented higher spontaneous vaginal delivery (SVD) rate (P < 0.05), and had shortened duration of first and second stages of labor and total duration of labor (P < 0.05). The incidence of both PPH and neonatal asphyxia in the study group was lower than that in the control group (both P < 0.05). The VAS, SAS and SDS scores in the study group were significantly lower than those in the control group (P < 0.05), and the patients' satisfaction in the study group was significantly higher (P < 0.05). CONCLUSION: Midwifery care is effective for the delivery of elderly parturients, which significantly improves VSD rate, shortens duration of labor, reduces incidence of PPH and neonatal asphyxia, as well as relives labor pain, anxiety and depression, and increases satisfaction of parturients.
RESUMEN
OBJECTIVE: It is unclear whether how people with long-term conditions express distress, and how clinicians respond, influences perceptions of consultation outcomes. The pilot study examined emotional distress and reassurance in consultations with people whose long-term conditions (at the time of consultations) were treated using active surveillance or symptom management (as no curative treatment was suitable). METHODS: An observational pilot study was conducted involving consultations between people with long-term conditions and their respective clinician. Consultations between three clinicians (two Huntington's Disease; one Prostate Cancer) and 22 people with long-term conditions (11 Huntington's Disease; 11 Prostate Cancer) were audio-recorded. Participants also completed an expanded Consultation and Relational Empathy (CARE) Measure. Two researchers coded sessions using Verona Coding Definitions of Emotional Sequences (VR-CoDES/VR-CoDES-P). Code frequencies were calculated, t tests performed between conditions, and Pearson's correlations performed for associations between CARE responses and clinician utterances. RESULTS: People with long-term conditions expressed emotional distress on average 4.45 times per session, averaging 1.09 Concern and 3.36 Cue utterances. Clinicians responded with more explicit (2.59) and space-providing (3.36), than non-explicit (1.86) and space-reducing (1.09), responses per session. Clinicians expressed spontaneous reassurance on average 5.18 times per session, averaging 3.77 Cognitive and 1.5 Affective reassurance utterances. Huntington's Disease consultations featured significantly more 'Cues', 'Concerns' and 'Overall' 'Emotional Distress', and 'Cognitive' and 'Overall' 'Reassurance'. CONCLUSION: Emotional distress was expressed more using hints than explicit concern utterances. Clinicians predominantly explicitly explored distress rather than providing information/advice and provided advice using spontaneous cognitive reassurance. People with Huntington's Disease expressed more concerns and received more reassurance, indicating different needs between conditions. Future research is required to explore emotional distress and reassurance in a larger sample of participants and long-term condition types, and how the practical implications of these findings may be used to enhance outcomes of consultations.

RESUMEN
Both the management and caregiving intervention of people living with HIV (PLWH), especially during acute HIV-1 infection, represent a public health issue and a form of social support. This current study analyzed the demographic and clinical factors associated with antiretroviral therapy (ART) adherence of PLWH from positive HIV diagnosis to ART initiation in a tertiary Chinese hospital in Beijing. A total of 200 participants diagnosed with acute HIV-1 infection were enrolled in this study. We collected demographic and clinical data by the use of a self-reported questionnaire. Bivariate and multivariate logistic regressions were used to determine associations between potential variables and outcomes. We found that medication adherence was impacted by years of ART and number of reminders (all P < 0.05). In addition, medication adherence was associated with viral load at 48 weeks (P = 0.035). Future studies are needed to investigate effective interventions that could facilitate ART adherence.

Transient-receptor-potential cation channel, subfamily M, member 3 (TRPM3) serves as a polymodal calcium sensor in diverse mammalian cell-types. Mutation of the human TRPM3 gene (TRPM3) has been linked with inherited forms of early-onset cataract with or without other eye abnormalities. Here, we have characterized the ocular phenotypes of germline "knock-in" mice that harbor a human cataract-associated isoleucine-to-methionine mutation (p.I65M) in TRPM3 (Trpm3-mutant) compared with germline "knock-out" mice that functionally lack TRPM3 (Trpm3-null). Despite strong expression of Trpm3 in lens epithelial cells, neither heterozygous (Trpm3+/- ) nor homozygous (Trpm3-/- ) Trpm3-null mice developed cataract; however, the latter exhibited a mild impairment of lens growth. In contrast, homozygous Trpm3-M/M mutants developed severe, progressive, anterior pyramid-like cataract with microphthalmia, whereas heterozygous Trpm3-I/M and hemizygous Trpm3-M/- mutants developed anterior pyramidal cataract with delayed onset and progression-consistent with a semi-dominant lens phenotype. Histochemical staining revealed abnormal accumulation of calcium phosphate-like deposits and collagen fibrils in Trpm3-mutant lenses and immunoblotting detected increased αII-spectrin cleavage products consistent with calpain hyper-activation. Immunofluorescent confocal microscopy of Trpm3-M/M mutant lenses revealed fiber cell membrane degeneration that was accompanied by accumulation of alpha-smooth muscle actin positive (α-SMA+ve) myofibroblast-like cells and macrosialin positive (CD68+ve) macrophage-like cells. Collectively, our mouse model data support an ocular disease association for TRPM3 in humans and suggest that (1) Trpm3 deficiency impaired lens growth but not lens transparency and (2) Trpm3 dysfunction resulted in progressive lens degeneration and calcification coupled with pro-fibrotic (α-SMA+ve) and immune (CD68+ve) cell responses.

Objective@#To investigate the general situation of sleep duration, sleep quality and related risk factors among primary students in Shanghai and to provide evidence for the prevention and control of students sleep health.@*Methods@#By using stratified cluster random sampling method, 3 410 students from 16 primary schools in four urban areas and four suburb areas of Shanghai were selected to conduct sleep health questionnaire survey and physical examination Chi square test was used for group comparison while binary Logistic regression was used to assess possible factors related with sleep quality.@*Results@#The detection rate of sleep insufficiency (<10 h) among students was 93.0%. The detection rate of poor sleep quality was 66.8% with 67.1% in girls and 66.6% in boys. The top three sleep problems were daytime sleepiness(80.9%), irregular sleep duration (74.1%) and sleep anxiety(59.5%). Multivariate Logistic regression analysis showed that everyday moderate-intensity physical activity (OR=1.51, 95%CI=1.04-2.21) and daily walking activity (more than 10 minutes)(OR=1.27, 95%CI=1.08-1.50) were risk factors of poor sleep quality(P<0.05).@*Conclusion@#In Shanghai, the prevalence of sleep insufficiency and poor sleep quality among primary students are high. Sleep health was associated with moderate physical activity and walking activity. Increasing the duration of moderate physical activity and daily walking activity is the very important measures in prevention and control of the sleep problems.
RESUMEN
Objective@#To investigate the relationship between body fat percentage (BF%) and high blood pressure among adolescents in Shanghai, and to provide basis for early prevention and intervention of cardcovascular diseases.@*Methods@#By using stratified cluster sampling method, a total of 5 148 adolescent students in 16 schools from 16 districts of Shanghai were selected. Questionnaire survey and physical examination were performed. The bioelectrical impedance analysis (BIA) was used to measure body fat percentage. National Blood Pressure Reference for Chinese Han Children was used to define high blood pressure. And T test, chi-square test and Logistici regression were used to assess the relation between BF% with high blood pressure.@*Results@#The prevalence of high blood pressure in 5 148 junior middle school students in Shanghai was 10.98%, with girls (13.13%) higher than boys (8.99%)(χ 2=22.48, P<0.01). The average total body fat percentage of male students was (20.90±10.73)%, which decreased with age (linear trend variance is 10.04, P<0.01). The average total body fat percentage of girls was (25.14±8.03)%, which increased with age (linear trend variance is 69.23, P<0.01). After adjusted for age, diet, exercise and other influencing factors, the prevalence of hypertension showed an increasing trend with the increase of body fat percentage for both boys and girls. The risk of high blood pressure in boys with BF%≥P 90 was 12.43 times higher than that in boys with BF%<P 25(95%CI=6.98-22.14), while the risk of high blood pressure in girls with BF% ≥P 90 was 6.12 times higher than that in girls with BF%<P 25(95%CI=3.89-9.63).@*Conclusion@#There was a positive correlation between body fat percentage and high blood pressure in adolescents. The prevalence of high blood pressure increased with the increase of body fat percentage, which was more obvious in boys.
RESUMEN
Background: The increasing involvement of social robots in human lives raises the question as to how humans perceive social robots. Little is known about human perception of synthesized voices. Aim: To investigate which synthesized voice parameters predict the speaker's eeriness and voice likability; to determine if individual listener characteristics (e.g., personality, attitude toward robots, age) influence synthesized voice evaluations; and to explore which paralinguistic features subjectively distinguish humans from robots/artificial agents. Methods: 95 adults (62 females) listened to randomly presented audio-clips of three categories: synthesized (Watson, IBM), humanoid (robot Sophia, Hanson Robotics), and human voices (five clips/category). Voices were rated on intelligibility, prosody, trustworthiness, confidence, enthusiasm, pleasantness, human-likeness, likability, and naturalness. Speakers were rated on appeal, credibility, human-likeness, and eeriness. Participants' personality traits, attitudes to robots, and demographics were obtained. Results: The human voice and human speaker characteristics received reliably higher scores on all dimensions except for eeriness. Synthesized voice ratings were positively related to participants' agreeableness and neuroticism. Females rated synthesized voices more positively on most dimensions. Surprisingly, interest in social robots and attitudes toward robots played almost no role in voice evaluation. Contrary to the expectations of an uncanny valley, when the ratings of human-likeness for both the voice and the speaker characteristics were higher, they seemed less eerie to the participants. Moreover, when the speaker's voice was more humanlike, it was more liked by the participants. This latter point was only applicable to one of the synthesized voices. Finally, pleasantness and trustworthiness of the synthesized voice predicted the likability of the speaker's voice. Qualitative content analysis identified intonation, sound, emotion, and imageability/embodiment as diagnostic features. Discussion: Humans clearly prefer human voices, but manipulating diagnostic speech features might increase acceptance of synthesized voices and thereby support human-robot interaction. There is limited evidence that human-likeness of a voice is negatively linked to the perceived eeriness of the speaker.
