Abstract
BACKGROUND Evidence suggests that arteriosclerosis and sarcopenia (decreased muscle mass) share some of their many causes. However, after controlling for confounding factors, it is unclear whether the presence of arteriosclerosis correlates with sarcopenia. OBJECTIVES The aim of this paper is to explore whether sarcopenia is associated with arteriosclerosis. DESIGN A multicenter cross-sectional community-based study. MATERIALS AND METHODS A total of 2511 elderly subjects from six Chinese community health service centers in Anhui province were surveyed through an e-health promotion system to collect basic data and measurements of brachial-ankle pulse wave (baPWV), body composition, and handgrip strength (HGS). Pearson's correlation and binary logistic regression analyses were performed to identify associations between sarcopenia and high baPWV. RESULTS The prevalence rates of sarcopenia were 12.9% in men and 15.3% in women according to the 2019 standard of Asian Working Group for Sarcopenia. Among subjects with high baPWV, the proportion of sarcopenia was higher compared to those with normal baPWV (men: 17.7% vs. 3.7%; women: 20.4% vs. 4.9%, both p<0.001). Binary logistic regression analysis revealed that sarcopenia was associated with high baPWV (p<0.0001, odds ratio=1.619) after adjusting for confounding factors. HGS slightly and negatively correlated with baPWV (-0.19 in men and -0.18 in women). CONCLUSIONS The intertwined pathophysiological mechanisms shared by arteriosclerosis and sarcopenia are potential targets for future interventions to reduce morbimortality in subjects with both disorders. Upcoming prospective studies and clinical trials are expected to advance these findings.

Abstract
AIMS Coronavirus disease 2019 (COVID-19) pandemic is a major public health concern all over the world. Little is known about the impact of COVID-19 pandemic on mental health in the general population. This study aimed to assess the mental health problems and associated factors among a large sample of college students during the COVID-19 outbreak in China. METHODS This cross-sectional and nation-wide survey of college students was conducted in China from 3 to 10 February 2020. A self-administered questionnaire was used to assess psychosocial factors, COVID-19 epidemic related factors and mental health problems. Acute stress, depressive and anxiety symptoms were measured by the Chinese versions of the impact of event scale-6, Patient Health Questionnaire-9 and Generalized Anxiety Disorder-7, respectively. Univariate and hierarchical logistic regression analyses were performed to examine factors associated with mental health problems. RESULTS Among 821 218 students who participated in the survey, 746 217 (90.9%) were included for the analysis. In total, 414 604 (55.6%) of the students were female. About 45% of the participants had mental health problems. The prevalence rates of probable acute stress, depressive and anxiety symptoms were 34.9%, 21.1% and 11.0%, respectively. COVID-19 epidemic factors that were associated with increased risk of mental health problems were having relatives or friends being infected (adjusted odds ratio = 1.72-2.33). Students with exposure to media coverage of the COVID-19 ≥3 h/day were 2.13 times more likely than students with media exposure <1 h/day to have acute stress symptoms. Individuals with low perceived social support were 4.84-5.98 times more likely than individuals with high perceived social support to have anxiety and depressive symptoms. In addition, senior year and prior mental health problems were also significantly associated with anxiety or/and depressive symptoms. CONCLUSIONS In this large-scale survey of college students in China, acute stress, anxiety and depressive symptoms are prevalent during the COVID-19 pandemic. Multiple epidemic and psychosocial factors, such as family members being infected, massive media exposure, low social support, senior year and prior mental health problems were associated with increased risk of mental health problems. Psychosocial support and mental health services should be provided to those students at risk.

Abstract
Objective: To study the characteristics of the lens turbidity after long-term exposure to low intensity 635nm laser. Methods: Cluster sampling method was adopted to select 812 employees in a laser leveler workshop in a city of Guangdong Province from January 2014 to December 2018. They were divided into the control group, diffuse reflection (DR) group and direct vision (DV) group for retrospective observation and analysis of lens turbidity. The laser irradiation intensity of each group was investigated, the position and shape of lens opacity were analyzed, and the influencing factors were statistically analyzed with the repeated measurement data of dichotomy. Results: The laser irradiance and radiant exposure of DV group were between 0.72×10(-4) and 9.92×10(-4) mW/cm(2) and between 2.61×10(-2) and 1.53 J/cm(2), respectively. The subjects were mainly diagnosed with lens turbidity lesion, especially for the DV group. Most of lesions occurred in the pole and periphery of the anterior cortex. The lesions exhibited multipoint patterns with greyish white color. The turbidity rates in DV group (before work and work for 1, 2, 3 years) were 0%, 1.99% (8/402) , 4.98% (20/402) and 6.72% (27/402) , respectively, in the order of observation points. The statistical analysis of single factor effect showed that the turbidity rate was higher in DV group and higher in the second year in the DV group (P<0.01) . Multi-factor analysis of the laser effect on the lens showed that the main effect between groups, between the observation point were statistically significant (P<0.05) , but no statistical significance in the interaction between group×observation points (P>0.05) . Conclusion: Lens turbidity lesion can be caused by long-term exposure to low intensity 635 nm laser, so the product safety classification should be strictly strengthened. It is necessary to strengthen the protection of laser photochemical damage in the production process.

Abstract
Immunohistochemistry results directly show VWF is increased during tumor progression. VWF is expressed as low molecular weight multimer in OS cell line SAOS2. VWF promotes platelet-induced metastasis of OS through VWF-GPIb pathway.
von Willebrand factor (VWF) is exclusively expressed in endothelial cells (ECs) and megakaryocytes, which plays a crucial role in the initiation of arterial thrombosis. Recent studies have shown that VWF is also expressed in osteosarcoma (OS) cells and participates in adhesion of cancer cells to platelets, thus promoting metastasis of OS cells. However, it is unclear how OS cell-derived VWF-platelet interaction contributes to the metastasis of OS. We hypothesized that the interaction is mediated by the binding between VWF A1 and GPIbα of platelets, a molecular mechanism similar to that of thrombosis. The increased expression of VWF in SAOS2 cells may contribute to the enhancement of platelet adhesion through the VWF-GPIb pathway, which could promote the migration and invasion capacities of SAOS2 cells in vitro. Antibodies that block the pathway could significantly inhibit the platelet-induced metastasis of OS cells. Our results suggest a theoretical basis for the development of new anti-OS metastasis drugs, and further enrich the mechanism of OS metastasis.

Abstract
OBJECTIVES Factors contributing to diminishing quality of life (QOL) of migrants have been examined, but little is known about the impact of relative deprivation. This study aimed to clarify the effects of relative deprivation on QOL and mediating effects of social exclusion among Chinese internal migrants. STUDY DESIGN This is a secondary data analysis of a nationally representative survey. METHODS We obtained data from 14,816 internal immigrants, aged 15-59 years, throughout China using the 2014 China Migrants Dynamic Survey (CMDS). We measured relative deprivation via a modified Yitzhaki Index, social exclusion using a four-point Likert scale, and QOL using the Kessler Psychological Distress Short Scale, the Satisfaction with Life Scale, and a subscale of the 36-item Short-Form Health Survey. Survey data of 15,996 local residents were also retrieved and analyzed to make possible comparisons between the local and migrant population. Furthermore, we used descriptive and statistical analyses with data from the CMDS to identify relative deprivation and social exclusion. RESULTS The results show relative deprivation both directly and indirectly influences Chinese internal migrants' QOL. Specifically, compared with the local population, relative deprivation triggers serious social exclusion (β = 0.008, P < 0.001), ultimately deteriorating QOL. Social exclusion partially mediated the total effects of relative deprivation on mental illness (β = 0.004, P < 0.001), self-rated health (β = -0.285, P < 0.001), and life satisfaction (β = -0.020, P < 0.001) among Chinese internal migrants. CONCLUSION Relative deprivation significantly impacts QOL by exacerbating mental illness, eroding self-rated health, and inhibiting life satisfaction. Relative deprivation is significantly directly associated with various indicators of QOL and indirectly affects QOL through social exclusion. In addition, our results demonstrate that the relative deprivation theoretical approach and the modified Yitzhaki Index are worthy of future investigation in studies of migrants' health.

Abstract
Objective: To explore the influence of laparoscopic radical gastrectomy on patients'immune functions, coagulation functions and prognoses. Methods: Fifty-eight patients with gastric cancer who underwent laparoscopic radical gastrectomy (laparoscopic group) and 40 patients with gastric cancer who underwent traditional open surgery (traditional group) in Henan People's Hospital from May 2016 to May 2018 were selected as the subjects. The immune function and coagulation function were compared between the two groups before and after operation. The prognoses of patients underwent laparoscopic radical gastrectomy and the influencing factors were analyzed. Results: Three days after operation, the CD4(+) level and CD4(+) /CD8(+) ratio in laparoscopic group were (29.78±3.58)% and (1.01±0.18), higher than (27.23±3.47)% and (0.93±0.14) in control group (P<0.05). Three days after operation, the activated partial thromboplastin time (APTT) in laparoscopic group was (26.55±2.56) seconds, shorter than (27.86±2.73) seconds in traditional group, while the levels of fibrinogen (FIB) and D-dimer were (4.24±0.84) g/L and (377.91±47.19) μg/L, higher than (3.88±0.75) g/L and (330.28±45.11) μg/L in traditional group (P<0.05). The 5-year survival rate was 77.5% in traditional group and 72.4% in laparoscopic group, without significant difference (P>0.05). Multivariate analysis showed that lymph node metastasis was the independent risk factor for prognosis of laparoscopic radical gastrectomy (P<0.05). Conclusions: Laparoscopic radical gastrectomy can effectively reduce postoperative immunosuppression, but affect postoperative coagulation function. Lymph node metastasis is closely related to the prognosis of patient with gastric cancer. The patient's condition should be comprehensively evaluated before and after operation to determine whether the laparoscopic operation is suitable, for reducing postoperative complications and improving the prognosis.

Abstract
PURPOSE OF REVIEW Maternal hypertension is a common and serious condition associated with increased maternal and foetal morbidity and mortality, with early detection and management improving outcomes. RECENT FINDINGS Blood pressure (BP) changes of pre-eclampsia are defined after 20 gestational weeks, while haemodynamic changes can be detected at 5-11 weeks using a specialised non-invasive Doppler stroke volume (SV) monitor. Thus, advanced haemodynamic monitoring allows for physiologically precise identification of circulatory abnormalities, and implementation of appropriate therapy within the first trimester. We measured the oscillometric BP and advanced haemodynamics (USCOM 1A) of 3 unselected women with singleton pregnancies, consecutively listed for therapeutic induction for maternal hypertension at 32-41 weeks gestational age. While the BP's of the patients varied, it was the haemodynamics, particularly SV, cardiac output, systemic vascular resistance, Smith Madigan Inotropy Index, and oxygen deliver, that identified differing patterns of circulatory dysfunction, therapeutic objectives, and predicted post-partum complications of the mother and child. First trimester screening of maternal haemodynamics may allow for earlier detection of circulatory derangements, selection of patient precise interventions, and improved maternal-foetal outcomes.

Abstract
As the most important transcription factor in the brassinosteroid (BR) signal transduction pathway, BES1 not only affects growth and development of plants but also regulates stress resistance of crops. The physicochemical properties, gene structure, cis-acting elements and gene chip expression of apple BES1 transcription factors were analysed using bioinformatics, and expression of this gene family was analysed with qRT-PCR. There were 22 members of the apple BES1 transcription factors, distributed on eight chromosomes, divided into seven subtribes (I-VII), and the same subtribe contained the same basic motifs. Gene structure analysis showed that the number and position of exons differed, and there was no upstream and downstream structure. Analysis of cis-acting elements indicated that BES1 transcription factors contain response elements for hormones and abiotic stress, as well as organ-specific elements. Gene chip expression profile analysis revealed that expression patterns of BES1 transcription factors differed in different apple hybrids and different organs. In addition, expression of apple BES1 genes was higher in flowers, young fruits, mature fruits and leaves. qRT-PCR demonstrated that expression of MdBES1 genes was highest 12 h after BR induction. At the same time, there were differences in expression in response to PEG, NaCl and MeJA. This paper provides a theoretical basis for analysis of the biological function and stress resistance mechanism of BES1 transcription factors in apple.
