Abstract
OBJECTIVE To investigate the clinical characteristics, imaging changes and early diagnostic methods of neuropsychiatric systemic lupus erythematosus (NPSLE). METHODS Thirty-five SLE patients, of which 16 had overt neuropsychiatric symptoms, underwent examination for multiple autoantibodies, including anti-double-stranded DNA (anti-dsDNA) antibody, anti-nucleosome antibody, anti-cardiac-phospholipid antibody (aCL)-IgG, aCL-IgM, anti-β2-glycoprotein I antibody and anti-ribosomal P antibody, and the SLEDAI score of every patient was recorded. All patients further received neuropsychological tests, including the Mini-Mental State Examination, the Self-Rating Anxiety Scale and the Self-Rating Depression Scale. Imaging examination using 3D arterial spin labeling was performed on 3.0 T MRI scanners. After processing the 3D arterial spin labeling image, the cerebral blood flow map was obtained and the cerebral blood flow value was calculated. RESULTS The values of anti-dsDNA, anti-nucleosome antibody, aCL-IgG and anti-β2-glycoprotein I antibodies were significantly higher in the NPSLE group than those in the SLE group. The SLEDAI scores of the NPSLE group were significantly higher than those of the SLE group. There were no significant differences between the NPSLE group and the SLE group in the directional ability, memory, attention, numeracy, recall ability or language ability scores on the Mini-Mental State Examination scale. Furthermore, there were no symptoms of anxiety or depression in any of the patients, according to the Self-Rating Anxiety Scale and Self-Rating Depression Scale. In the 35 patients with SLE, decreases in blood perfusion were seen in some areas, and were unilateral and asymmetrically distributed. There was obvious asymmetry between sides in areas including the frontal lobe, temporal lobe, parietal lobe and occipital lobe. The incidence of perfusion decreases in frontal lobe in the NPSLE group was significantly higher than in the SLE group. CONCLUSION Neurological lesions in SLE patients can be detected by arterial spin labeling. Cerebral blood flow abnormalities may be helpful for the early diagnosis of neurological lesions in NPSLE.

Abstract
BACKGROUND Glioma is a type of tumor that occurs in the brain and accounts for almost 30 % of all brain and central nervous system tumors and 80 % of all malignant brain tumors. In this study, we investigate the role of cAMP response element-binding protein (CREB) in the progression of glioma. METHODS Tissue samples from glioma patients were collected and examined for expression of CREB and its correlation with tumor grades. CREB was then knocked down via siRNA to see if reduced expression of CREB affects cell proliferation and migration. Factors involved in cell cycles, adhesion and apoptosis were examined as well. Moreover, CRESP/CAS9 mediated knockout of CREB was conducted and athymic Nude mice model was used to investigate CREB's role in vivo. RESULTS The evaluated expression level of CREB in glioma patients was correlated with tumor grades. Knockdown of CREB via siRNA in glioma cell line U251 significantly inhibited the proliferation and migration of tumor cells. Moreover, CyclinD1 and Bcl-2 expression were reduced, as well as phosphorylation of IRK1/2 and AKT. Additionally, knockout of CREB via CRESP/CAS9 inhibited tumor formation of U251 cells in athymic Nude mice model. CONCLUSIONS In conclusion, our data suggest that over expression of CREB may contribute to progression of glioma and knockdown of CREB expression may serve as a novel target for therapy (Tab. 1, Fig. 6, Ref. 25).

Abstract
Objective: To investigate the clinical features and T lymphocytes subsets in patients with acquired immune deficiency syndrome (AIDS) and cytomegalovirus (CMV) infection. Methods: A total of 48 hospitalized patients with human immunodeficiency virus (HIV)-1/AIDS and CMV infections were recruited at Peking Union Medical College Hospital from Jan 2010 to Aug 2017. Their clinical features and immune function were retrospectively analyzed. Patients with only HIV/AIDS in previous study were recruited as controls. Results: All 48 patients were at C3 stage, including 36 men and 12 women. Five of them were younger than 30 years old, 33 cases within 31-50 years old, and 10 cases older than 50 years old. Thirty-five patients had CD(4)(+)T lymphocytes ≤ 50 cells/μl, 7 cases with CD(4)(+)T cells 51-100/μl, 3 cases with 101-200 cells/μl, and 3 cases over 200 cells/μl. As to CMV infections, there were 31 cases of CMV viremia, 1 case of CMV encephalitis, 1 case of CMV enteritis, 5 cases of CMV pneumonia, and 9 cases of CMV retinitis. Other opportunistic infections were also common including 16 cases of pneumocystis pneumonia, 9 cases of tuberculosis, 5 cases of syphilis, 18 cases of digestive tract fungal infections, 8 cases of pulmonary fungal infections, 2 cases of EB virus infections, 2 cases of HIV encephalopathy/progressive multifocal leukoencephalopathy (PML), 3 cases of cryptococcal meningitis, 1 case of toxoplasma infection. In group of both CMV and HIV/AIDS infections, 100% patients had inverted CD(4)(+)/CD(8)(+) ratio. The immune activation marker CD(8)(+)CD(38)(+)/CD(8)(+) was higher (61.6%-98.8%) with a median value of 91.2% in 40 patients. HLA-DR(+)CD(8)(+)/CD(8)(+), another marker for T cell activation, was 25.5%-98.0% in 44 patients with a median value of 60.3%. Thirty-six patients had both immune activation markers positive. There was no significant difference in counts of B cells, natural killer cells, CD(4)(+) T cells, CD(8)(+) T cells and immune activation subsets stratified by gender and age (P>0.05). Meanwhile, neither serum HIV viral load nor serum CMV viral load was correlated with HLA-DR(+)CD(8)(+)/CD(8)(+), CD(8)(+)CD(38)(+)/CD(8)(+), CD(4)(+)T cell counts, and CD(4)(+)/CD(8)(+) ratio in the CMV and HIV/AIDS co-infection group (all P>0.05), while HIV viral load in HIV/AIDS only group was significantly correlated with HLA-DR(+)CD(8)(+)T/CD(8)(+), CD(38)(+)CD(8)(+)/CD(8)(+), CD(4)(+) T cell counts, CD(4)(+)/CD(8)(+) ratio (r=0.473, 0.575, -0.767 and -0.678, respectively, all P<0.05). Conclusions: CMV infections develop in HIV patients with advanced stage. CMV infection can cause life-threatening multiple organ lesions, especially in those with CD(4)(+) T cells less than 100 cells/μl. It is of great importance to screen CMV-IgM, pp65 antigen, CMV DNA to make early diagnosis and treatment.

Abstract
OBJECTIVE To explore the influential factors of kidney transplant patients' self-management, especially psychosocial variables. STUDY DESIGN This was a cross-sectional study. METHODS Questionnaires were administered to patients with the assistance of our team members to gather sociodemographic information, medical characteristics, self-management, social support, depression, and flourishing. RESULTS The study included 483 patients, 64.4% of whom were male. The score index of the total self-management scale was 81.95% and the "social psychology" dimension had the lowest index, at 75.63%. Higher scores for flourishing, shorter length of post-renal transplantation, more social support, lower body mass index, being female, and being employed were proved to be determinants of better self-management, and flourishing was identified as having the greatest influence. Some other indicators were also related to patients' self-management, particularly age, residence, income, hypertension, renal function, and depression. CONCLUSION The overall self-management of KT patients was middling, and the status of psychology management was not optimistic. This emphasized the importance of psychological intervention. For further exploration, flourishing was identified as contributing to better self-management, which implied that strengthening this factor could be another method of improving self-management, except that involves enhancing of social support and reducing depression. Age was also found to have differing degrees of influence on KT patients' self-management, which implies that younger patients should receive more support in self-management.

Abstract
Objective: To observe the cellular damage of low-dose combined exposure to Hg, Pb and Cd on hippocampal neurons in rat. Methods: SH-SY5Y cells were randomly divided into 8 groups by 2×2×2 factorial design: control group, Pb exposure group, Hg exposure group, Pb+Hg exposure group, Pb+Cd exposure group, Hg+Cd exposure group and Pb+Cd+Hg exposure group. And the cell viabilities were measured. On this basis, an animal model was established. Twenty eight-week-old SD pregnant rats were randomly divided into four groups by random number table, and five in each group: the control group(distilled water), 1-fold metal mixture exposure group (1×MM, poisoning solution containing mercury chloride 0.15 mg/L, lead acetate trihydrate 25 mg/L, cadmium chloride 7.5 mg/L), 5-fold metal mixture exposure group (5×MM, poisoning solution containing mercury chloride 0.75 mg/L, lead acetate trihydrate 125.00 mg/L, cadmium chloride 37.50 mg/L), 10-fold metal mixture exposure group (10×MM, poisoning solution containing mercury chloride 1.50 mg/L, lead acetate trihydrate 250.00 mg/L, cadmium chloride 75.00 mg/L). Pregnant rats drank water until delivery. Twenty male pups were selected and exposed to these metals through breast milk until weaned. The heavy metals dose of poisoning water was adjusted, and then the weaned rats were exposed to heavy metals via drinking poisoning water until adulthood (postnatal day 83). The blood samples and brain hippocampus samples were collected to observe the ultrastructural changes of hippocampus, and to determine the levels of Hg, Pb and Cd in blood. In addition, apoptosis rate and fluorescence intensity of reactive oxygen species and intracellular free calcium concentration ([Ca(2+)](i)) in hippocampal neurons were measured. Results: Cellular factorial design analysis showed that Hg+Pb+Cd (at no observed adverse effect level, 1.0, 0.5 and 0.1 μmol/L, respectively)had a interaction on cell viability after 48 or 72 hours of combined exposure (P<0.05). The results of ultrastructure showed that mitochondria decreased, ridges and matrixes gradually dissolved in rat hippocampal neurons of 5×MM group; nuclear chromatin aggregated, more ridges and matrixes dissolved and the mitochondria also decreased in rat hippocampal neurons of 10×MM group. The concentration of Hg, Pb and Cd in the blood of 1×MM group, 5×MM group and 10×MM group were higher than those in the control group, and the differences were statistically significant (P<0.001). There was no significant difference in apoptosis rate between the 1×MM group and the control group. The apoptosis rate of 5×MM group and 10×MM group was higher than that in the control group, and the differences were statistically significant (P<0.001). There was no statistically significant difference in the fluorescence intensity of reactive oxygen species in hippocampal neurons of the 1×MM group and the control group. The fluorescence intensity of reactive oxygen species in the 5×MM group and the 10×MM group was higher than that in the control group, the difference was statistically significant (P<0.05). There was no significant difference in the fluorescence intensity of [Ca(2+)](i) between the 1×MM group and the control group. The fluorescence intensity values of [Ca(2+)](i) in the 5×MM group and the 10×MM group were higher than the control group, the differences were statistically significant (P<0.001). Conclusion: Low-level combined exposure to Hg, Pb, and Cd caused synergistic neurotoxic damage, and the process may be related to the changes of neuronal apoptosis, reactive oxide species, and [Ca(2+)](i) levels.

Abstract
BACKGROUND The prevalence of Candida infections in paediatric intensive care units (PICUs) has dramatically increased as a result of resistance to conventional anti-fungal treatments. Because vitamin D has been shown to exhibit fungicidal activity against Candida infection in an in vitro antimicrobial screening, we aimed to investigate the effect of vitamin D on Candida infections in the PICU. METHODS Four hundred sixteen eligible children aged between 12 months to 5 years old admitted to the PICU, who were on broad-spectrum antibiotic therapy, participated in the study. Patients were randomly assigned to two study groups, receiving a plain yogurt drink (placebo group) or supplemented with 300 IU day-1 vitamin D (VD group). Primary outcome was defined as the incidences of Candida colonisation (Candida isolated from rectal swab) 14 days after enrollment. Secondary outcome measures were Candida growth in blood (candidaemia) and urine (candiduria). RESULTS The prevalence of candiduria as well as candidaemia was significantly lower in the VD-treated group (26 cases) than in the placebo group (62 cases). The mean (SD) length of PICU stay was obviously lowered in the VD group [11.8 (1.2) days] compared to the placebo group [15.2 (2.3 days)], whereas cases of patient death were similar between the two groups. CONCLUSIONS Supplementation of vitamin D effectively reduces infections of Candida in children who were critically ill and on broad-spectrum antibiotic treatment.

Abstract
BACKGROUND To investigate neonatal maternal separation (NMS) effects on airway inflammation of asthma and potential mechanism using a mouse model. METHODS 80 Balb/c neonatal male mice were randomly assigned to NMS and non-NMS groups. Feces were collected on PND21, 28, 35 and 42 to analyze microbiota and short-chain fatty acids (SCFAs). Non-NMS group were then divided into control (group A) and asthma groups (group B), while NMS group was assigned to NMS+asthma (group C) and NMS+SCFAs+asthma groups (group D). Inflammatory cells and eosinophils (EOS) in bronchoalveolar lavage fluid (BALF) were assessed. Pathological changes and cytokines in lung tissue were observed. Protein expression of Occludin and E-cadherin in airway epithelial was examined. RESULTS The number of S', diversity index H' and dominance index D', as well as content butyric acid in NMS group C were significantly lower than non-NMS group B (p<0.05). Mice in group C had a higher level of inflammatory cells and EOS compared with group A, B and D. EOS moderate infiltration was found in mice of group B, C and D. Mice in group C had significantly higher levels of cytokines and showed slightly increased bronchial epithelium goblet cells and a small amount of visceral secretions. Occludin and E-cadherin expression in lung in B, C and D groups was depressed, and protein level in group C was significantly lower than group B and D. CONCLUSIONS NMS is associated with exacerbated inflammation of adult asthma by changing intestinal microflora resulting in butanoic acid decline and airway epithelial barrier damage.

Abstract
Objective: To study the distribution of sub-health and occupational stress as well as their correlation among middle school teachers in Tianjin, then provide evidences for prevention and control of the status of sub-health. Methods: A total of 3 522 middle school teachers from six districts of Tianjin were recruited with stratified cluster sampling strategy for the investigation of Sub-Health Measurement Scale version 1.0 (SHMS V1.0) and Occupational Stress Inventory-Revised Edition (OSI-R) . Results: Detection rate of sub-health status among Tianjin middle school teachers was 58.55%. Men had significantly lower sub-health detection rate (55.19%) than women (59.71%) . Sub-health detection rate increased with age (P<0.05) , the sub-health detection rate among middle school teachers more than 50 years old was the highest (66.84%) . The mean score of OSI-R was 403.18±41.80 with the scores of 176.00±21.05, 103.17±17.53, and 124.02±20.28 for ORQ, PSQ, PRQ, respectively, which showed significantly difference compared with the occupational stress norm of China (P<0.001) . The mean scores of OSI-R, ORQ, PSQ, PRQ in different health status were significantly different (P<0.001) . The partial correlation analysis between the scores of sub-health and occupational stress of middle school teachers showed that the scores of occupational role and personal strain were negatively correlated with the scores of sub-health state (P< 0.001) , while, there was significantly positive correlation between the scores of personal resource and the scores of sub-health state (P<0.001) . Conclusion: Sub-health detection rate of middle school teachers in Tianjin is higher. Effective measures should be taken to appropriately mitigate the occupational stress level of middle school teachers, increase personal resources, and scientific and effective health guidance and education should be strengthened.

Abstract
Objective:To study the effects of stromal interaction molecule 1 (STIM1) RNA interference on cell proliferation, apoptosis, invasion and migration ability in vitro in human laryngeal cancer cells Hep-2. Method:Lentivirus transfection was used to realize the STIM1 RNA interference in human laryngeal cancer cells Hep-2. STIM1 RNA interference was verified by real-time PCR and western blotting. The cell proliferation was analyzed by CCK-8 method, Transwell chamber and wound scratch assay were used to detect cell invasion and migration ability, respectively. The cell apoptosis rate was evaluated by flow cytometry. The apoptotic proteins expression levels of caspase-3, Bax, Bcl-2, VEGF and MMP9 were detected by western blotting. Result:The gene expression levels of STIM1 mRNA and protein in human laryngeal cancer cells Hep-2 were significantly decreased after interference lentivirus transfection. After the interference of STIM1, the cell proliferation, invasion and migratory ability of Hep-2 cells in vitro declined (P<0.05). The cell apoptosis rate significantly increased after STIM1 RNA interference, along with the caspase-3 and Bax protein expression levels up-regulation, and the Bcl-2 expression levels down-regulation. The decrease of cell invasion and migratory ability was related with the down-regulation of VEGF and MMP9 protein expression. Conclusion:RNA interference of STIM1 in human laryngeal cancer cells Hep-2 inhibits the cell proliferation, invasion and migration ability in vitro, and enhances the cell apoptosis rate of Hep-2 cells.

Abstract
BACKGROUND Several studies have examined sleep quality in the post renal transplant population of China, but few studies have actually confirmed the related psychosocial variables of sleep quality in renal transplant recipients with home care. OBJECTIVES This study investigates sleep quality and its related psychosocial variables among renal transplant patients. METHODS This is a cross-sectional study using a convenient sampling approach. Self-report questionnaires were applied to 485 renal transplant patients. All participants completed the General Data Questionnaire, the Pittsburgh Sleep Quality Index (PSQI), the Self-Rating Depression Scale, the Three-Dimensional Inventory of Character Strengths, and the Flourishing Scale. RESULTS A total of 438 valid questionnaires were included in the analysis. The global PSQI score was 5.86 (SD, 3.20), significantly lower than the norm; 128 (29.2%) recipients were classified as having poor sleep quality (global PSQI > 7). In the component score of PSQI, sleep onset latency was the highest; the others from high to low are sleep disturbance, daytime dysfunction, subjective sleep quality, sleep efficiency, sleep duration, and use of hypnotic medication. A total of 19.6% reported sleeping fewer than 6 hours a night, 64.8% reported that they had to get up to use the bathroom, and 50.0% woke up in the middle of the night or early morning at least 1 night per week in the past month. Significant differences in the PSQI scores were observed in renal transplant patients of different sex, age, residence, career, length of post-renal transplant period, comorbidity, kidney function, and depressive symptoms (P < .05). The PSQI scores were positively correlated with depression (Self-Rating Depression Scale) (P < .01) but negatively correlated with inquisitiveness (Three-Dimensional Inventory of Character Strengths-inquisitiveness) and psychological well-being (Flourishing Scale) (P < .01). CONCLUSION The sleep quality of renal transplant patients was lower than that of the general population. Character strengths and well-being can increase the level of sleep quality in renal transplant patients. Psychosocial intervention is necessary for improving the sleep quality of renal transplant recipients in China.

Abstract
OBJECTIVES To evaluate the relationship between individual bacterial and viral pathogens and disease severity. METHODS Children <18 years with three or more episodes of vomiting and/or diarrhoea were enrolled in two Canadian paediatric emergency departments between December 2014 and August 2016. Specimens were analysed employing molecular panels, and outcome data were collected 14 days after enrolment. The primary outcome was severe disease over the entire illness (symptom onset until 14-day follow-up), quantified employing the Modified Vesikari Scale (MVS) score. The score was additionally analysed in two other time periods: index (symptom onset until enrolment) and follow-up (enrolment until 14-day follow-up). RESULTS Median participant age was 20.7 (IQR: 11.3, 44.2) months; 47.4% (518/1093) and 73.4% (802/1093) of participants had index and total MVS scores ≥11, respectively. The most commonly identified pathogens were rotavirus (289/1093; 26.4%) and norovirus (258/1093; 23.6%). In multivariable analysis, severe disease over the entire illness was associated with rotavirus (OR = 9.60; 95%CI: 5.69, 16.19), Salmonella (OR = 6.61; 95%CI: 1.50, 29.17), adenovirus (OR = 2.53; 95%CI: 1.62, 3.97), and norovirus (OR = 1.43; 95%CI: 1.01, 2.01). Pathogens associated with severe disease at the index visit were: rotavirus only (OR = 6.13; 95%CI: 4.29, 8.75), Salmonella (OR = 4.59; 95%CI: 1.71, 12.29), adenovirus only (OR = 2.06; 95%CI: 1.41, 3.00), rotavirus plus adenovirus (OR = 3.15; 95%CI: 1.35, 7.37), and norovirus (OR = 0.68; 95%CI: 0.49, 0.94). During the follow-up period, rotavirus (OR = 2.21; 95%CI: 1.50, 3.25) and adenovirus (OR = 2.10; 95%CI: 1.39, 3.18) were associated with severe disease. CONCLUSIONS In children presenting for emergency department care with acute gastroenteritis, pathogens identified were predominantly viruses, and several of which were associated with severe disease. Salmonella was the sole bacterium independently associated with severe disease.

Abstract
Herpesviral haematopoietic necrosis (HVHN), caused by cyprinid herpesvirus 2 (CyHV-2), causes significant losses in crucian carp (Carassius carassius) aquaculture. Rapid and convenient DNA assay detection of CyHV-2 is useful for field diagnosis. Recombinase polymerase amplification (RPA) is a novel isothermal DNA amplification and detection technology that can amplify DNA within 30 min at ~37°C by simulating in vivo DNA recombination. Herein, a rapid and convenient detection assay based on RPA with a lateral flow dipstick (LFD) was developed for detecting CyHV-2. The highly conserved ORF72 of CyHV-2 was targeted by specific and sensitive primers and probes. The optimized assay takes only 15 min at 38°C using a water bath, with analysis of products by 2% agarose gel electrophoresis within 30 min. A simple lateral flow strip based on the unique probe in reaction buffer was developed for visualization. The entire RPA-LFD assay takes 50 min less than the routine PCR method, is 100 times more sensitive and displays no cross-reaction with other aquatic viruses. The combined isothermal RPA and lateral flow assay (RPA-LFD) provides a simple, rapid, reliable method that could improve field diagnosis of CyHV-2 when resources are limited.

Abstract
Objective: To study the correlation between the level of serum Chitinase-3-like protein 1 (CHI3L1) and the significant liver fibrosis and liver cirrhosis in patients with chronic liver disease, and to evaluate its diagnostic value. Methods: 165 patients with chronic liver disease were selected, liver histopathological examination was performed to detect serum CHI3L1 concentration. Four indexes of hepatic fibrosis (type III procollagen, collagen IV, laminin, hyaluronic acid), aspartate aminotransferase/platelet ratio index (APRI) and FIB-4 (fibrosis- 4) scores were based on the pathological findings of liver biopsy and compared the advantages and disadvantages of serum CHI3L1 with other methods for the diagnosis of hepatic fibrosis and liver cirrhosis. A multivariate regression analysis model was created, and receiver operating characteristic curve was analyzed. Results: The level of serum CHI3L1 increased with increase of fibrosis stage and was highest in liver cirrhosis stage. In the period of S0 to 1, the levels of S2 to 3 and S4 were 62.82 (41.40 ~ 87.20), 70.94 (48.47 to 122.60) and 141.06 (78.18 ~ 197.40), and there were statistically significant differences between the groups (P < 0.001). The area under the curve for the diagnosis of significant liver fibrosis was 0.68 (0.60 to 0.77), and 0.74 (0.65 to 0.83) for cirrhosis in CHI3L1. Multivariate regression analysis showed that CHI3L1 was an independent predictor of significant fibrosis and cirrhosis. The combined diagnostic model based on CHI3L1, collagen IV and FIB-4 scores further improved the diagnostic value. The area under the curve for the diagnosis of significant fibrosis and cirrhosis was 0.79 (0.72 to 0.86) and 0.80 (0.73 to 0.87), respectively. Conclusion: CHI3L1 has a good diagnostic value in patients with chronic liver disease with significant fibrosis and liver cirrhosis. The diagnostic model in combination with other markers like Collagen IV and FIB-4 scores could further improve the diagnostic value and is worthy of further study.
