Frequency of depressive symptoms among female migrant workers in China: associations with acculturation, discrimination, and reproductive health. Public Health 2020; 181:151-157. [PMID: 32036172 DOI: 10.1016/j.puhe.2019.12.006] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/06/2019] [Revised: 11/18/2019] [Accepted: 12/05/2019] [Indexed: 10/24/2022]
Abstract
OBJECTIVES Depression has been associated with numerous adverse health conditions. This study sought to determine the frequency of significant depressive symptoms and whether or not acculturative stress, discrimination, and reproductive health conditions were risk factors for significant depressive symptoms in migrant working women in China. STUDY DESIGN The design of this study is cross-sectional. METHODS Data were derived from a survey of female migrant workers at three employment sites in Changsha, China. The associations between acculturative stress, discrimination, reproductive health, and risk for significant depressive symptoms were obtained using F-tests for mean differences, correlations, ordinary least squares regression, and logistic regression analysis. RESULTS Between March and June 2017, 232 eligible female participants completed the survey among whom the median age was 34.36 years (standard error 0.43) and 25.58% reported significant depressive symptoms. Significant depressive symptoms were associated with higher education (F-test, P = .006), all four acculturative stress factors (r = 0.15 to r = 0.29), both institutional and interpersonal discrimination (r = 0.29, r = 0.35), age (r = - 0.13), and self-rated health (r = - 0.19). In multivariate regression analysis of depression scale scores, interpersonal discrimination was the strongest predictor (beta = 0.238, P = .002) among the nine factors identified in bivariate analysis. None of the other predictors (age, self-rated health, education, acculturative stress, and institutional discrimination) showed significant associations with the depression scale. Similar results were obtained for a multivariate logistic regression analysis of a clinically important threshold for depression (<10 versus ≥ 10 on the depression scale). Only interpersonal discrimination significantly distinguished between clinical depression categories (odds ratio = 2.607 per unit change in the index, P = .001). CONCLUSIONS Migrant women workers in China appear to be at risk for significant depressive symptoms, and interpersonal discrimination appears to be an important risk factor in this setting. Acculturative stress and institutional discrimination may also be relevant risk factors, as suggested in our bivariate analysis, but in our sample, the correlations between the stress and discrimination factors are high enough to compromise identification of unique associations between acculturation stress and depression. Government, community and workplace education, and psychosocial services for migrant women are recommended.

Abstract
BACKGROUND The immune system is one of the most complex regulatory systems in the body and is essential for the maintenance of homeostasis. Despite recent breakthroughs in immunology, the regulation of the immune system and the etiology of autoimmune diseases such as lupus remain unclear. Systemic lupus erythematosus is a systemic autoimmune disease with abnormally and inconsistently expressed pro-inflammatory cytokines. Pyroptosis is a pro-inflammatory form of programmed cell death that is associated with systemic lupus erythematosus. The thymus and spleen are important immune organs involved in systemic lupus erythematosus. Therefore, this study investigated the difference in expression of pyroptosis-inducing pro-inflammatory cytokines between the spleen and thymus in lupus model mice and in control mice, to describe immune regulation at the organ level. OBJECTIVE To investigate differences in the expression of pyroptosis-inducing cytokines in the spleen and thymus and to explore immune regulatory networks at the organ level. METHODS Two groups of lupus mice and two groups of control mice were utilized for this study. Using the thymus and spleen of experimental animals, mRNA expression levels of five pyroptosis-inducing cytokines (interleukin 1β, interleukin 18, NLRP3, caspase-1 and TNF-α) were determined via quantitative polymerase chain reaction. In addition, tissue distribution of these cytokines was investigated via immunohistochemistry. RESULTS All five pyroptosis-inducing inflammatory cytokines showed higher expression in the spleen than in the thymus (p < 0.05). Moreover, the spleen/thymus expression ratios of all five pyroptosis-inducing cytokines were not statistically different between the four experimental groups. Expression of all five cytokines exhibited a stable ratio (spleen/thymus ratios). This distinctive stable spleen/thymus ratio was consistent in all four experimental groups. The stable spleen/thymus ratios of the five inflammatory cytokines were as follows: interleukin 1β (2.02 ± 0.9), interleukin 18 (2.07 ± 1.06), caspase-1 (1.93 ± 0.66), NLRP3 (3.14 ± 1.61) and TNF-α (3.16 ± 1.36). Immunohistochemical analysis showed the cytokines were mainly expressed in the red pulp region of the spleen and the medullary region of the thymus, where immune-activated cells aggregated. CONCLUSION The stable spleen/thymus expression ratios of pyroptosis-inducing cytokines indicated that immune organs exhibit strictly regulated functions to maintain immune homeostasis and adapt to the environment.

Abstract
INTRODUCTION Multiple sclerosis (MS) is a complex demyelinating disease involving central nervous system (CNS). It is still a challenge to secure an effective therapeutic strategy against this disease. Carbenoxolone (CBX) is a derivative of glycyrrhetinic acid, which is widely used in brain research for its gap-junction inhibition effects. Many researchers have observed CBX-mediated suppression of CNS inflammation in their studies. OBJECTIVE We want to further examine its anti-inflammation effects in CNS demyelinating disease like MS. METHODS Thus, our study applied an experimental autoimmune encephalomyelitis (EAE) mouse model and examined the effects of CBX on it. RESULTS AND CONCLUSIONS We found that CBX significantly reversed the EAE severity and pathology in EAE. IL-17-secreting and IFN-γ-secreting CD4+ T lymphocytes were remarkably lower in the spleen of CBX-treated mice. Production of IL-23 and IL-17 from cortex in EAE animals was markedly reduced by CBX. Furthermore, CBX treatment increased the expression of brain-derived neurotrophic factor. This study provides evidence for the protective role of CBX against EAE.

Abstract
OBJECTIVES No pictorial questionnaire is available for screening sarcopenia. We aimed to develop a self-reported cartoon questionnaire based on the SARC-F and the Finger-Ring test and to compare its diagnostic accuracy with the SARC-F and the SARC-F combined with calf circumference (SARC-CalF). DESIGN A diagnostic accuracy study. SETTING Urban communities in Chengdu, China. PARTICIPANTS Older adults aged ≥ 60 years. METHODS We established a multidiscipline team to design this pictorial questionnaire, entitled Self-Reported Cartoon SARC-CalF (cSARC-CalF). We used the Asian Working Group for Sarcopenia (AWGS) criteria as the "gold standard" of sarcopenia. We performed sensitivity/ specificity analyses of the three tools (cSARC-CalF, SARC-CalF, and SARC-F) and applied the receiver operating characteristics (ROC) curves and the area under the ROC curves (AUC) to compare the diagnostic accuracy of the three tools. RESULTS We included 1,009 participants. Using the Youden Index method, the cutoff of the cSARC-CalF for identifying sarcopenia was set as ≥11 points. Both the cSARC-CalF and the SARC-CalF showed better sensitivity but similar specificity than the SARC-F for identifying sarcopenia (sensitivity: 33.3%, 41.4%, and 23.0%; specificity: 90.1%, 85.9%, and 88.1%). The AUCs of the cSARC-CalF, SARC-CalF, and SARC-F were 0.74 (95% CI, 0.71 - 0.77), 0.79 (95% CI, 0.76 - 0.81), and 0.67 (95% CI, 0.64 - 0.70), respectively. The difference in AUCs between cSARC-CalF and SARC-F and the difference in AUCs between SARC-CalF and SARC-F was statistically significant (p=0.012 and p<0.001, respectively). However, the difference in AUCs between cSARC-CalF and SARC-CalF was not significant (p=0.109). CONCLUSION The cSARC-CalF showed a better overall diagnostic accuracy than the SARC-F and a similar overall diagnostic accuracy as the SARC-CalF in Chinese community-dwelling older adults. It may serve as a new tool for screening sarcopenia; however, it needs to be validated in other populations.

Abstract
OBJECTIVE Myeloma severely threatens public health, and molecular targeting treatment becomes the future perspective. Dual specificity phosphatases (DSUP) protein has multiple functions including modulating cell proliferation, differentiation, aging, and apoptosis. Whether DUSP can regulate myeloma cell is unclear. This study thus aimed to investigate the effect of DUSP on myeloma cell line RPMI8226 cell aging and provide evidence for the clinical treatment of myeloma. MATERIALS AND METHODS H2O2-induced aging model of myeloma cell line RPMI8226 was generated. DUSP over-expression plasmid or specific siRNA was transfected by liposome. Western blot was used to detect the expression of DUSP in RPMI8226 cells. Cell aging condition was evaluated by β-galactosidase assay. Aging proteins P53 and P16 expression levels, the activation of TLR4 signal pathway were tested by immunoblotting. TLR4 signal pathway was then suppressed by Verteporfin for testing RPMI8226 cell aging. RESULTS Growing levels of DUSP, aging proteins P53 and P16, with inhibition of TLR4 signal pathway were found in the H2O2-induced aging model of myeloma cell line RPMI8226. Transfection of DUSP over-expression plasmid or siRNA potentiated or inhibited the aging of RPMI8226 cells induced by H2O2 and suppressed or enhanced TLR4 signal pathway, respectively. Verteporfin, an inhibitor of TLR4, increased the level of P53 and aging of RPMI8226 cells. CONCLUSIONS DUSP facilitates H2O2-induced aging of myeloma cell line RPMI8226 and suppresses TLR4 expression, which provides academic basis for clinical intervention.

Abstract
Objective: To compare the dosimetric parameters of three different modern radiation techniques in radical radiotherapy for esophageal cancer. Methods: A total of 25 patients with pathologically confirmed esophageal squamous cell carcinoma in Zhejiang Cancer Hospital were included from September 2015 to May 2016 and three radiation treatment plans for helical tomotherapy (TOMO), intensity-modulated radiotherapy (IMRT) and volumetric-modulated arc therapy (VMAT) were designed respectively for each patient. Study patients included 24 males and 1 female,aged from 47 to 82 years old, with a median age of 63 years old. All patients received the total prescription dose of 60 Gy in 30 fractions to the planning target volume (PTV). Conformity index (CI), heterogeneity index (HI), D(1), D(2), D(50), D(95), D(98), D(9)9 and V(95), V(100), V(105) of PTV was calculated. The mean dose, V(5), V(10), V(20), V(30), V(40) and V(50) of total lung, heart, and maximum dose (D(max)) to spinal cord were recorded as well. Results: Compared with TOMO and IMRT, VMAT showed higher CI (0.81±0.08) and lower HI (0.10±0.05), and CI was worse in IMRT (0.77±0.05) than TOMO (0.79±0.04) (t=2.604, P=0.016) and VMAT (t=2.817, P=0.010). There was no significant difference in HI among three radiation techniques. The dosimetric parameters of TOMO in normal lung were significantly better than those of VMAT and IMRT, especially in V(20) and V(30). The D(max) of spinal cord (38.24±3.72) Gy in TOMO was significantly lower than that of the VMAT ((39.88±3.27)Gy, t=-3.173, P=0.004) and IMRT plan ((41.09±3.18)Gy, t=-5.559, P=0.000). Subgroup analysis showed that VMAT was superior to TOMO and IMRT in CI and HI, especially HI (0.09±0.01) significantly better than TOMO (0.12±0.03, t=3.024, P=0.029) and IMRT (0.12±0.02, t=-3.800, P=0.013) for patients with cervical and upper thoracic esophageal cancer. TOMO and VMAT were significantly better than IMRT in MLD, lung V(20) and V(30) (all P<0.05). TOMO (38.46±2.15)Gy was significantly superior to VMAT ((41.02±1.28)Gy,t=-2.701, P=0.043) and IMRT ((41.76±1.11)Gy, t=-3.111, P=0.027) at D(max) of the spinal cord. For the patients with middle and lower thoracic esophageal cancer, TOMO, VMAT and IMRT had no statistically significant differences in CI and HI. IMRT was inferior to TOMO and VMAT in MLD, lung V(10), V(20), and V(30) (all P<0.05). TOMO (38.17±4.14) Gy was significantly superior to VMAT ((39.52±3.64)Gy,t=-2.219, P=0.040) and IMRT ((40.87±3.59)Gy,t=-4.528, P=0.000) at D(max) of the spinal cord. Conclusions: The VMAT plan is better than TOMO and IMRT in terms of the conformal degree and dose uniformity of the target volume.TOMO seems significantly better than VMAT and IMRT in protecting normal tissue.

Abstract
Background Morphine is a common analgesic often used to manage chronic pain, especially for patients with pain due to malignancies. Since UGT2B7 plays an important role in the metabolism of morphine, UGT2B7 gene mutation may influence the efficacy of morphine in patients with cancer being treated by this medication. Aims The aim of this study is to investigate the relationship between the polymorphisms of UGT2B7 and the efficacy of morphine treatment on cancer pain among the Chinese Han population. Materials and Methods A total of 120 patients with cancer pain were enrolled in this study. Morphine was administrated through patient-controlled analgesia infusion pump, and the visual analog score (VAS) was used for pain assessment at 0.5, 4, 6, 12, 24, 48, and 72-h post morphine treatment, respectively. The plasma concentration of morphine and genetic polymorphism of UGT2B7 C802T and G221T was analyzed, respectively. Results The frequencies of UGT2B7 C802T were CC: 13.33%, CT: 45% and TT: 41.67%, and the frequencies of UGT2B7 G221T were GG: 76.67%, GT: 22.5% and TT: 0.83%. Moreover, the VAS score of patients with either C802T CT or TT was significantly higher than that in patients with C802T CC. However, no difference of VAS scores was observed between patients carrying G221T GG and patients carrying G221T GT. The plasma concentration of morphine for patients with the C802T CC was significantly lower than that in patients carrying C802T CT or TT, while there was no significant difference in the level of morphine between patients with G221T GG and G221T GT. Conclusion The polymorphism of UGT2B7 C802T, but not UGT2B7 G221T, has been associated with the efficacy of morphine treatment on cancer pain among Chinese Han population.

Abstract
Background Cheilitis granulomatosa (CG) is a disturbing and persistent idiopathic lip swelling. The cause and treatment has not been wholly elucidated. Some reports infer that CG is mainly associated with dental infection but no firm or reliable microbiological evidence has been provided for a causative organism. This study aimed to evaluate whether microorganisms contribute to the etiology of CG in order to inform appropriate treatment options in clinic. Material and Methods Unstimulated saliva was collected from 15 CG patients who were diagnosed clinically and pathologically and 15 healthy controls (HC). DNA was extracted from the precipitate of the centrifuged saliva for 16s rRNA high-throughput sequencing using the Miseq PE300 platform. The distribution of the microbiome between the two groups was compared. Results CG patients had a greater microbial flora that was more diverse than the HC. Prevotella, Alloprevotella, Porphyromonas, Actinomyces, Rothia, Fusobacterium, Haemophilus, and Aggregatibacter had a significantly higher abundance in CG patients. In contrast, Streptococcus and Campylobacter were the most abundant genera in HC with a mean relative abundance of 63% and 2%, respectively. The microbiological network indicated that most of the bacteria that were enriched at greater levels in CG patients were likely to be Prevotella, Actinomyces, and Rothia. These have been shown to co-exist with other bacteria. Conclusions: The composition and structure of bacterial communities in CG patients were different from HC. Most of the genera observed in CG patients were associated with periodontitis and pulp infection. These findings might be helpful in understanding the etiology of CG. Further study will be needed to confirm these findings and explore the underlying pathological mechanism. Key words:Cheilitis granulomatosa, 16s rRNA high-throughput sequencing, salivary microbiota.

Abstract
Memristive switches are able to act as both storage and computing elements, which make them an excellent candidate for beyond-CMOS computing. In this paper, multi-input memristive switch logic is proposed, which enables the function X OR (Y NOR Z) to be performed in a single-step with three memristive switches. This ORNOR logic gate increases the capabilities of memristive switches, improving the overall system efficiency of a memristive switch-based computing architecture. Additionally, a computing system architecture and clocking scheme are proposed to further utilize memristive switching for computation. The system architecture is based on a design where multiple computational function blocks are interconnected and controlled by a master clock that synchronizes system data processing and transfer. The clocking steps to perform a full adder with the ORNOR gate are presented along with simulation results using a physics-based model. The full adder function block is integrated into the system architecture to realize a 64-bit full adder, which is also demonstrated through simulation.

Abstract
Abstract
Background
Cardiovascular disease is the leading cause of death in the world. The majority of cardiovascular events result from the rupture of vulnerable atherosclerotic plaques, which are characterized by high and active macrophage content. The integrin αVβ3 is expressed by activated macrophages and endothelial cells in atherosclerotic lesions and thus is a marker of high-risk plaques. Therefore, 89Zr-RGD-melanin nanoparticle (MNP) positron emission tomography (PET)/photoacoustic imaging (PAI) imaging of αVβ3 expression in plaques might provide a novel noninvasive biomarker of plaque vulnerability.
Purpose
In this study, the intrinsic photoacoustic signals and the native strong chelating properties with metal ions of MNP, positron-emitting metal ions 89Zr and αVβ3 integrins targeting ability of cyclic c (RGDfC) peptide was employed to construct an efficient nanoplatform. And we evaluated the feasibility of 89Zr-RGD-MNP PET/PAI of αVβ3 expression in vivo and in vitro.
Methods
We conjugated αVβ3 integrins, cyclic c (RGDfC) peptide, to MNP and chelated the long-lived positron-emitting nuclide 89Zr. The bio-stability and targeting action was detected in macrophages. And the PET/PAI imaging was performed in apoE−/− mice with partial carotid ligation leading to atherosclerosis. In PET imaging, tracer uptake was measured in the stenotic areas of the carotid arteries, as well as on the contralateral side at different time points in vivo. In PAI, photoacoustic signal was measured in the atherosclerosis of the carotid arteries in vivo. Melanin staining and immunohistochemistry of αVβ3 expression were detected in atherosclerosis of the carotid arteries.
Results
89Zr-RGD-MNP showed excellent bio-stability and targeting action. PET imaging showed specific tracer accumulation at plaques in the left carotid artery, confirmed by competitive receptor blocking studies and the contrast in the right carotid artery. In the biodistribution studies, the left carotid (5.29%±0.78%) showed higher uptake than the right carotid (2.11%±1.55%). PAI showed the PA signal in the surgery group (452±85 a.u.) were stronger than the control (156±45 a.u.) and blocking group (254±66 a.u). The result was consistent with PET imaging and the presence of nanoparticles, as indicated by pathological examinations. These results presented good in vivo multimodality imaging (PET/PAI) properties.
Conclusions
We have developed 89Zr-labeled atherosclerotic plaques imaging agents based on the natural melanin nanoparticle. 89Zr-RGD-MNP demonstrates specific tracer accumulation in mice atherosclerotic carotid plaques. In this model, its uptake was associated with αVβ3 expression. 89Zr-RGD-MNP is a potential tracer for noninvasive imaging in atherosclerosis.

miR-142-3p Inhibits the Metastasis of Hepatocellular Carcinoma Cells by Regulating HMGB1 Gene Expression. Curr Mol Med 2019; 18:135-141. [PMID: 30198432 DOI: 10.2174/1566524018666180907161124] [Citation(s) in RCA: 20] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/18/2018] [Revised: 07/15/2018] [Accepted: 09/04/2018] [Indexed: 11/22/2022]
Abstract
BACKGROUND Non-coding small RNAs are involved in organism development, and their aberrant regulation induces various diseases, including hepatocellular carcinoma (HCC), but their exact mechanisms have not been determined. OBJECTIVE The aim was to investigate the role of miR-142-3p on HMGB1 expression in hepatocellular carcinoma. METHODS Expression levels of miR-142-3p in HCC tissues and cultured cells were measured by RT-PCR. The invasion and metastasis abilities of HepG2 cells according to Transwell migration and invasion assays, and protein expression was measured by western blotting. RESULTS The present study reported that miR-142-3p promotes the invasion and migration of HCC cells. miR-142-3p levels are lower in HCC tissues than in adjacent non-cancerous tissues, suggesting a tumor suppressor role for miR-142-3p. Highmobility group box protein 1 (HMGB1) is an oncogene that promotes the metastasis of HCC. miR-142-3p or HMGB1 knockdown alone inhibits the invasion and migration of HCC cells, and HMGB1 overexpression impedes the effect of miR-142-3p. Further studies showed that HMGB1 is a direct target gene of miR-142-3p in HCC. miR-142-3p represses HMGB1 gene transcription by directly binding to the 3' untranslated region (UTR) of HMGB1, thereby inhibiting cancer cell invasion and migration. CONCLUSION This study, for the first time, reports that miR-142-3p is a novel tumor suppressor that inhibits the invasion and migration of HCC cells by directly regulating gene transcription of HMGB1. Thus, miR-142-3p may be a potential diagnostic and therapeutic biomarker for HCC patients.

Mesenchymal stromal cells attenuate multiple sclerosis via IDO-dependent increasing the suppressive proportion of CD5+ IL-10+ B cells. Am J Transl Res 2019; 11:5673-5688.

Abstract
Multiple sclerosis (MS), one of the autoimmune and inflammatory diseases, is a major cause of neurological disability worldwide. The existing clinical treatments are not curable, and better treatments are urgently needed. Mesenchymal stromal cells (MSCs) have shown promise for treating MS, but the favorable effects and mechanism of MSC therapy on MS are still not fully understood. In this study, we analyzed the phenotypic feature of peripheral blood mononuclear cells (PBMCs) in MS patients and found that the patients exhibited an increase in the frequency of B cells, but a markedly decrease in frequency of CD5+ and IL-10+ B cells compared to healthy controls. Infusion of MSCs exhibited a significant therapeutic effect on the experimental autoimmune encephalomyelitis (EAE) mice, infiltration of mononuclear cells and demyelination of the spinal cords were both reduced in CNS of the mice, the frequency of CD5+ IL-10+ B cells in the mice was significantly increased. Additionally, when PBMCs or B cells from MS patients were co-cultured with MSCs, the frequency of CD5+ IL-10+ B cells also increased, the proliferative and immunosuppressive capacity of CD5+ B cells were significantly enhanced while the apoptosis ratio of this cellular subset significantly decreased. Moreover, those effects could be eliminated while the indoleamine 2,3-dioxygenase (IDO) inhibitor, D/L-1MT, was added to the co-cultured cells. In summary, this study suggests that MSCs can control EAE via IDO pathway to promote the proportion and function of CD5+ IL-10+ B cells, providing a promise to treat patients with MS in the clinical setting.

Abstract
Programmed cell death protein 1 (PD-1), as a checkpoint of the immune signaling pathway, is a hotspot in the field of immuno-oncology. Its binding with ligand (PD-L1) is an important negative regulatory mechanism. Application of PD-1/PD-L1 inhibitors in treatments of breast cancer is still being explored at present. Fully understanding the mechanism of PD-1/PD-L1 in the microenvironment of breast cancer will help their inhibitors play a full role. This review will start with the discovery of PD-1 and PD-L1, describe their main signaling pathways, introduce the common types and applications of PD-1/PD-L1 inhibitors, especially in breast cancer, summarize the basic research of PD-1 and PD-L1 in breast cancer microenvironment in recent years, and seek new strategies of PD-1/PD-L1 inhibitors in breast cancer treatment.

HLA class II allele DRB1*16:02 is associated with anti-NMDAR encephalitis. J Neurol Neurosurg Psychiatry 2019; 90:652-658.

Abstract
BACKGROUND AND OBJECTIVE Aetiology and pathogenesis of anti-N-methyl-D-aspartate receptor (anti-NMDAR) encephalitis, the most common autoimmune encephalitis, is largely unknown. Since an association of the disease with the human leucocyte antigen (HLA) has not been shown so far, we here investigated whether anti-NMDAR encephalitis is associated with the HLA locus. METHODS HLA loci of 61 patients with anti-NMDAR encephalitis and 571 healthy controls from the Chinese Han population were genotyped and analysed for this study. RESULTS Our results show that the DRB1*16:02 allele is associated with anti-NMDAR encephalitis (OR 3.416, 95% CI 1.817 to 6.174, p=8.9×10-5, padj=0.021), with a higher allele frequency in patients (14.75%) than in controls (4.82%). This association was found to be independent of tumour formation. Besides disease susceptibility, DRB1*16:02 is also related to the clinical outcome of patients during treatment, where patients with DRB1*16:02 showed a lower therapeutic response to the treatment than patients with other HLA alleles (p=0.033). Bioinformatic analysis using HLA peptide-binding prediction algorithms and computational docking suggested a close relationship between the NR1 subunit of NMDAR and the DRB1*16:02. CONCLUSIONS This study for the first time demonstrates an association between specific HLA class II alleles and anti-NMDAR encephalitis, providing novel insights into the pathomechanism of the disease.

Abstract
OBJECTIVE The objective of this study was to observe the expression features of erythroblast macrophage protein (EMP) between the tissues of MRL/lpr mice, a mouse model of systemic lupus erythematosus (SLE), and control mice. METHODS We examined the serum ANA in both mice groups through indirect immunofluorescence (IIF). Expression features of EMP in bone marrow, liver, renal, spleen, brain, and lung tissues of the MRL/lpr mice and control mice groups were followed using quantitative real-time polymerase chain reaction (Q-PCR). Meanwhile, the expression of EMP was located through immunohistochemical (IHC) studies and the expressive cell identified through double immunofluorescent labeling. RESULTS IIF showed that lupus mice have strong positive fluorescence, but no significant fluorescence was observed in control mice. Q-PCR detection revealed that EMP was expressed in the marrow, liver, renal, spleen, lung, and brain tissues of lupus mice. The highest levels were observed in the bone marrow, but there was no statistical difference between these tissues. EMP mRNA expression in the liver (t = 2.747, p = 0.01) and bone marrow (t = 3.853, p = 0.008) of lupus mice was significantly higher than in the control mice. However, no differences in EMP mRNA expression were observed in the renal, spleen, lung, and brain tissues between the lupus and control mice (p > 0.05). In addition, the IHC results showed that EMP protein is ubiquitously expressed in all of the tissues of the lupus and control mice. The positive expression rate in the bone marrow and liver tissues of the lupus mice was higher than in the control mice, but without an obvious difference in the other tissues. The double IF staining method shows that EMP protein was expressed in macrophages in the tissues of the lupus mice and the control mice. CONCLUSIONS Our data showed that EMP is ubiquitously expressed in macrophages at all of the tissues of the lupus and control mice. However, the expression of EMP in bone marrow and liver tissues of lupus mice was higher than in the control mice, which indicates that EMP may be important in the development of SLE.

Abstract
Salt reduction is the most cost-effective population strategy to prevent and control hypertension and cardiovascular disease. Accurate measurement of salt intake is an important basis for implementing salt reduction interventions, while the urine sodium measurement is the most objective method to evaluate salt intake. According to different time spans, it is mainly divided into 24-h urine, overnight urine and spot urine collection methods. This article reviewed the application and evaluation of these three urine measurement methods, and compared their advantages and disadvantages. According to the accuracy and feasibility of different urine measurement methods, it is suggested that the 24-h urine collection method can be applied to the correlation study with small sample size, and the overnight urine method and the spot urine method can be applied to the daily population salt reduction interventions and monitoring activities.

Abstract
Bioavailability is not a constant percentage of a contaminant in food but is affected by many factors, such as food type, treatment, diet structure and interaction with other compounds. To evaluate these influences, we measured the bioaccessibility of aflatoxins from nine naturally polluted maize samples, collected from southeast China, using an in vitro digestion model, and analysed the intestinal transport of aflatoxins by a Caco-2 cell model. Steam cooking treatment could reduce the aflatoxin levels in maize bread. The degradation rates of aflatoxin B1, aflatoxin B2, aflatoxin G1, and aflatoxin G2 ranged from 24.9±3.2 to 33.9±3.5%, 27.0±2.0 to 39.0±1.8%, 27.9±7.9 to 34.4±8.2% and 25.6±3.6 to 37.2±6.5%, respectively. As a result, the bioaccessibility of aflatoxins determined by an in vitro digestion model (41.5-63.3%) was much lower than the previously reported 80%. Edible oil could increase the bioaccessibility of aflatoxin, whereas lettuce would decrease the exposure amount from maize. With a Caco-2 cell model, the apparent permeability coefficient exceeding 10-5 cm/s indicated that there is high absorption of aflatoxins in the human body, while the intestinal transport can be effectively restrained in the presence of chlorophyll.

Abstract
Objective: The aim of this research was to study the prevalence and differences of depressive symptoms and related factors in elderly in both urban and rural areas so as to develop relative strategies on this issue. Methods: Ten-question-version of the Center Epidemiologic Studies-Depression scale (CES-D) was applied to score the depressive status. Data used in this research was from the 2013 China Health and Retirement Longitudinal Study (CHARLS). Binary logistic regressions method was applied to examine the influential factors related to depression symptoms. Results: In the elderly population, the mean score on depressive symptoms was 8.3±5.9, with a prevalence as 26.8%. The incidence rates on 'Elderly depression' in urban and rural areas were 16.4% and 30.0% respectively. The prevalence of depressive symptoms was relatively low (P<0.05) with protective factors including: being male, status related to self-rated health, without chronic diseases, active participation in social activities etc. noticed, among elderly in both urban and rural areas. Age and alcohol consumption appeared factors that influencing the depressive symptoms of the elderly in rural areas, while the average income was an influencing factor on the elderly in urban areas. Incidence of depression was relatively low in age ≥75 years group in rural areas. However, elderly in the rural areas with abstinence of alcohol intake showed higher incidence of depressive symptoms (P<0.05). Incidence of depression was reltively low (P<0.05) among elderly with high income in the urban areas. Conclusions: Incidence of depression appeared high among the elderly and even higher in the rural areas. Strategies would include the following points: to strengthen the construction of urban-rural integration, improving and strengthening the rural pension insurance system, upgrading the urban social assistance for low-income elderly, strengthening the psychological consultation service of primary medical institutions and actively developing the three-tier levels related to the prevention of chronic diseases.

Abstract
BACKGROUND We conducted a single-arm phase II trial to evaluate the efficacy and adverse effects (AEs) of an anti-epidermal growth factor receptor monoclonal antibody, nimotuzumab, combined with cisplatin and 5-fluorouracil (PF) as first-line treatment in recurrent metastatic nasopharyngeal carcinoma after radical radiotherapy. METHODS Patients who met the eligibility criteria were recruited from ten institutions (ClinicalTrials.gov; NCT01616849). A Simon optimal two-stage design was used to calculate the sample size. All patients received weekly nimotuzumab (200 mg) added to cisplatin (100 mg/m2 D1) and 5-fluorouracil (4 g/m2 continuous infusion D1-4) every 3-weekly for a maximum of six cycles. Primary end point was objective response rate (ORR). Secondary end points included disease control rate (DCR), progression-free survival (PFS), overall survival (OS) and AEs. RESULTS A total of 35 patients were enrolled (13 in stage 1 and 22 in stage 2). Overall ORR and DCR were 71.4% (25/35) and 85.7% (30/35), respectively. Median PFS and OS were 7.0 (95% CI 5.8-8.2) months and 16.3 (95% CI 11.4-21.3) months, respectively. Unplanned exploratory analyses suggest that patients who received ≥2400 mg nimotuzumab and ≥4 cycles of PF had superior ORR, PFS and OS than those who did not (88.9% versus 12.5%, P < 0.001; 7.4 versus 2.7 months, P = 0.081; 17.0 versus 8.0 months, P = 0.202). Favourable subgroups included patients with lung metastasis [HROS 0.324 (95% CI 0.146-0.717), P = 0.008] and disease-free interval of >12 months [HROS 0.307 (95% CI 0.131-0.724), P = 0.004], but no difference was observed for metastatic burden. The only major grade 3/4 AE was leukopenia (62.9%). CONCLUSION Combination nimotuzumab-PF chemotherapy demonstrates potential efficacy, and is well tolerated as first-line chemotherapy regimen in recurrent metastatic nasopharyngeal carcinoma.
