Abstract
BACKGROUND Repetitive transcranial magnetic stimulation (rTMS) is an effective adjuvant treatment for depression. Many patients with depression have comorbid anxiety symptoms. However, previous rTMS studies have focused on patients with depression, and often excluded comorbid anxiety. This real-world study aimed to investigate the comparative efficacy of add-on rTMS in treating the somatic and psychic anxiety symptoms of depression comorbid with anxiety in adolescents, adults and elderly patients. METHODS This study included 147 depression patients with anxiety symptoms who were treated with at least 10 sessions of rTMS. The symptoms of anxiety and depression were assessed with the Hamilton Rating Scale for Anxiety (HAMA) and the Hamilton Rating Scale for Depression (HAMD) at baseline and after 2 and 4 weeks of treatment. This was done to compare the improvement degree of add-on rTMS on somatic and psychic anxiety symptoms in adolescents, adults and elderly patients respectively. RESULTS Both somatic and psychic anxiety symptoms were significantly improved after the add-on rTMS in adolescents, adults and elderly patients. The improvement of somatic anxiety was better than that of psychic anxiety after rTMS treatment in elderly patients (t2w=3.895, P<0.001; t4w=2.823, P = 0.008). LIMITATION The overall sample was mostly composed of elderly patients, while adolescents and adult patients were fewer. CONCLUSIONS The add-on rTMS treatment can improve somatic anxiety better than psychic anxiety in depression with anxiety symptoms, especially in elderly patients.

Abstract
IMPORTANCE Transgender or gender nonconforming (TGNC) adolescents face a wide range of physical and mental health concerns. However, there has been no school-based study to explore the prevalence and mental health status of these adolescents in mainland China. OBJECTIVES To assess the mental well-being of TGNC adolescents in China by comparing them with their cisgender peers. DESIGN, SETTING, AND PARTICIPANTS This was a cross-sectional survey study. Of the 12 354 adolescents who completed the questionnaire, 246 did not specify to which sex they identified and were therefore excluded from further analysis. Therefore, a total of 12 108 adolescents were included from 18 secondary schools in Suzhou city, China, from June 2019 to July 2019. Participants provided consent and answered questions on sex assigned at birth and gender identity. MAIN OUTCOMES AND MEASURES All participants completed questionnaires, including the Patient Health Questionnaire for the measurement of depressive symptoms, a generalized anxiety disorder screening, the Pittsburgh Sleep Quality Index, and a self-harm and suicide risk checklist. The frequency of being bullied at school was also measured. Participants who reported their perceived gender as the opposite of their assigned sex at birth were classified as transgender, those who identified as neither male nor female were classified as nonbinary, and those who were not sure about their perceived gender were classified as questioning. All of these participants were categorized as TGNC adolescents. RESULTS A total of 12 108 adolescents (mean [SD] age, 15.8 [1.0] years; 6518 [53.8%] assigned male at birth [AMAB]) participated in the study. Of the 6518 participants AMAB in the sample, 5855 (89.8%) were classified as cisgender boys, 208 (3.2%) as transgender girls (transgender youth who perceive their current gender identity to be female), 138 (2.1%) as nonbinary youth AMAB, and 317 (4.9%) as questioning youth AMAB. Of the 5590 participants assigned female at birth (AFAB), 4142 (74.1%) were classified as cisgender girls, 861 (15.4%) as transgender boys (transgender youth who perceive their current gender identity to be male), 112 (2.0%) as nonbinary youth AFAB, and 475 (8.5%) as questioning youth AFAB. Compared with cisgender adolescents, TGNC adolescents reported significantly higher health concerns including lower overall health (t11 872 = -7.36; P < .001), poorer sleep (t11 683 = 10.49; P < .001), higher depression and anxiety symptoms (t11 830 = 12.43 and t11 847 = 11.47, respectively; P < .001), and higher rate of self-harm and suicide ideation (t11 860 = 12.22; P < .001). The TGNC youth who were AMAB were also more likely to be bullied at school than cisgender boys (transgender girls: odds ratio [OR], 2.34 [95% CI, 1.64-3.33]; nonbinary youth AMAB: OR, 1.97 [95% CI, 1.23-3.16]; and questioning youth AMAB: OR, 1.95 [95% CI, 1.43-2.67]). The TGNC groups also reported significantly greater amounts of thoughts of self-harm (transgender girls: OR, 3.06 [95% CI, 2.24-4.19]; transgender boys: OR, 4.06 [95% CI, 3.47-4.74]; nonbinary youth AMAB: OR, 2.86 [95% CI, 1.93-4.23]; nonbinary youth AFAB: OR, 3.71 [95% CI, 2.46-5.59]; questioning youth AMAB: OR, 2.61 [95% CI, 1.98-3.44]; and questioning youth AFAB: OR, 3.35 [95% CI, 2.70-4.16]), thoughts of suicide (transgender girls: OR, 3.93 [95% CI, 2.88-5.38]; transgender boys: OR, 3.71 [95% CI, 3.10-4.21]; nonbinary youth AMAB: OR, 3.13 [95% CI, 2.11-4.63]; nonbinary youth AFAB: OR, 3.78 [95% CI, 2.50-5.71]; questioning youth AMAB: OR, 2.53 [95% CI, 1.93-3.33]; and questioning youth AFAB: OR, 3.94 [95% CI, 3.17-4.88]), suicide plan formation (transgender girls: OR, 4.44 [95% CI, 2.88-6.83]; transgender boys: OR, 2.66 [95% CI, 2.03-3.50]; nonbinary youth AMAB: OR, 5.36 [95% CI, 3.22-8.93]; nonbinary youth AFAB: OR, 4.06 [95% CI, 2.25-7.30]; and questioning youth AFAB: OR, 2.36 [95% CI, 1.63-3.43]), deliberate self-harm during the last month (cisgender girls: OR, 1.49 [95% CI, 1.33-1.68]; transgender girls: OR, 2.74 [95% CI, 1.93-3.91]; transgender boys: OR, 3.06 [95% CI, 2.57-3.66]; nonbinary youth AMAB: OR, 2.56 [95% CI, 1.66-3.94]; nonbinary youth AFAB: OR, 3.06 [95% CI, 1.95-4.81]; questioning youth AMAB: OR, 2.14 [95% CI, 1.56-2.92]; and questioning youth AFAB: OR, 2.53 [95% CI, 2.00-3.01]), and attempts of suicide (transgender girls: OR, 4.35 [95% CI, 2.88-6.56]; transgender boys: OR, 2.92 [95% CI, 2.26-3.76]; nonbinary youth AMAB: OR, 3.94 [95% CI, 2.36-6.55]; nonbinary youth AFAB: OR, 3.06 [95% CI, 1.67-5.63]; questioning youth AMAB: OR, 2.61 [95% CI, 1.73-3.94]; and questioning youth AFAB: OR, 1.93 [95% CI, 1.33-2.81]) compared with cisgender boys. CONCLUSIONS AND RELEVANCE Results of this cross-sectional survey study suggest poor mental health status among TGNC adolescents in China; in addition, findings suggest a compelling need for researchers, practitioners, and policy makers to address these mental health problems. Particular school-based interventions are recommended to support the mental health well-being of TGNC adolescents.

Abstract
INTRODUCTION Prior work suggests that involvement in bullying was associated with a higher suicide risk among adolescents. However, the mechanisms of this association remain unclear. The present study aimed to understand the relationship between direct and indirect involvement in bullying (bullying victimization, bullying perpetration and bullying witnessing) and suicide risk by examining the serial mediation of negative coping styles and depressive symptoms. METHODS 12,354 Chinese adolescents (mean age = 15.00, 54% male) were recruited from December 2018 to January 2019 in 18 secondary schools. Participants completed questionnaires that measured their direct and indirect involvement in bullying, negative coping styles, depressive symptoms, and suicide risk. RESULTS The relationship between involvement in bullying and suicide risk was mediated by negative coping styles, depressive symptoms, and also serially mediated by negative coping styles and depressive symptoms. Similar findings were obtained for both direct and indirect involvement in bullying. LIMITATIONS The present study is limited by a cross-sectional design. Future studies could examine longitudinal changes in the outcome measures CONCLUSIONS: Given the urgent need to reduce the high suicide rate among adolescents in China, our findings suggest that having a less negative coping style is an important protective factor. These results provide direction for the development of prevention strategies and targeted interventions within this population. Additionally, it is essential to develop prevention strategies and interventions not only for those who have been a victim or perpetrator of bullying, but also for those who have witnessed bullying.

Abstract
BACKGROUND Many patients with major depressive disorder (MDD) have been found to have psychotic symptoms. However, few studies have reported the prevalence of comorbid psychotic symptoms in first-episode drug naïve (FEDN) MDD patients. This study was to investigate the prevalence of psychotic symptoms and related risk factors in a large sample size of FEDN MDD patients in a Chinese population. METHODS A total of 573 patients with diagnosis of MDD at their first episode were recruited with their demographic and clinical data. Positive scale of the Positive and Negative Syndrome Scale was utilized for psychotic symptoms, Hamilton Anxiety Rating Scale (HAMA) for anxiety symptoms, and Hamilton Depression Rating Scale (HAMD) for depressive symptoms. RESULTS The prevalence of psychotic symptoms in these MDD patients was 9.8%. MDD patients with psychotic symptoms had significantly higher HAMD and HAMA total scores than those without psychotic symptoms (both p < .001). A strong association was found between psychotic MDD and anxiety or suicide, with odds ratio of 33.097 for severe anxiety, and 5.012 for suicide. CONCLUSIONS Our results suggest that psychotic symptoms are common in MDD patients at their first episode. The strong association between psychotic MDD and anxiety or suicide attempts demonstrates the importance of reducing anxiety symptoms in the treatment of psychotic MDD patients as well as the necessity to regularly assess suicide risk in MDD patients with psychotic symptoms to better prevent suicidal behavior.

Abstract
Objective: To analyze the correlation between the changes of lung function and serum proinflammatory cytokines in workers occupationally exposed to toluene diisocyanate (TDI), and to explore the evaluation index of respiratory toxicity of TDI. Methods: In October 2014, 61 male workers engaged in TDI synthesis process, purification process, packaging process and the above production process in a TDI factory in western China were selected as TDI exposure group; 62 male enterprise managers who were not exposed to TDI and other known allergenic chemicals were selected as control group, which were matched at the age of workers in exposure group. The questionnaire survey obtained information such as gender, length of service, age, occupational history, exposed length of service and so on. The lung function indexes [forced expiratory volume in the first second (FEV1), forced vital capacity (FVC), FEV1/FVC] and serum levels of interleukin (IL)-1 β, IL-6, IL-8, tumor necrosis factor (TNF)-α, macrophage inflammatory factor-1 β, monocyte chemoattractant factor-1 and vascular endothelial growth factor were measured. The urine was collected after the weekend shift, and the concentration of (TDA), the metabolite of TDI, was determined as the index of internal exposure. Spearman rank correlation was used to analyze the correlation between cytokines and lung function indexes, and multivariate linear regression was used to analyze the changes of lung function indexes and cytokines with TDI exposure concentration and time. Results: The median age (P5-P95) of the exposed group and the control group was 36.5 (24.0-51.0) and 38.0 (24.0-50.0) years, respectively. In the exposed group, the median length of service (P5-P95) was 6.94 (0.97-26.33) years, and the median concentration of TDA in urine was 15.56 (2.28-112.16) ng/ml. The three indexes of lung function, FVC, FEV1, FEV1/FVC and the levels of serum IL-8 and TNF-α were significantly lower than those in the control group (P<0.01). With the increase of exposure concentration and exposure time, the level of serum TNF-α, FVC and FEV1 decreased, and showed a good dose-effect and time-effect relationship (all Ptrend values< 0.05). Serum IL-8 and TNF-α were positively correlated with FVC, FEV1 and FEV1/FVC (all P values<0.01). Conclusion: The levels of serum inflammatory factors IL-8 and TNF-α in worker exposed to TDI are related to lung function indexes, which can be used as early evaluation indexes of respiratory toxicity induced by TDI.

Abstract
BACKGROUND Electroconvulsive therapy (ECT) has been shown to be effective in schizophrenia (SZ), particularly in drug-refractory cases or when rapid symptom relief is needed. However, its precise mechanisms of action remain largely unclear. To clarify the mechanisms underlying modified electroconvulsive therapy (mECT) for SZ, we conducted a longitudinal cohort study evaluating functional connectivity of the thalamus before and after mECT treatment using sub-regions of thalamus as regions of interest (ROIs). METHODS Twenty-one SZ individuals taking only antipsychotics (DSZ group) for 4 weeks and 21 SZ patients receiving a regular course of mECT combining with antipsychotics (MSZ group) were observed in parallel. All patients underwent magnetic resonance imaging scans at baseline (t1) and follow-up (t2, ~4 weeks) time points. Data were compared to a matched healthy control group (HC group) consisting of 23 persons who were only scanned at baseline. Group differences in changes of thalamic functional connectivity between two SZ groups over time, as well as in functional connectivity among two SZ groups and HC group were assessed. RESULTS Significant interaction of group by time was found in functional connectivity of the right thalamus to right putamen during the course of about 4-week treatment. Post-hoc analysis showed a significantly enhanced functional connectivity of the right thalamus to right putamen in the MSZ group contrasting to the DSZ group. In addition, a decreased and an increased functional connectivity of the thalamus to sensory cortex were observed within the MSZ and DSZ group after 4-week treatment trial, respectively. CONCLUSION Our findings suggest that changes in functional connectivity of the thalamus may be associated with the brain mechanisms of mECT for schizophrenia.

Abstract
Brain-derived neurotrophic factor (BDNF) plays an important role in the treatment of schizophrenia with electroconvulsive therapy (ECT) or antipsychotic (AP) drugs. However, it is unclear whether BDNF is a mediator; we therefore assumed that baseline BDNF level can mediate the efficacy of ECT-AP treatment. A total of 160 patients with schizophrenia were examined; 80 received AP monotherapy and the other 80 were treated with a combination of ECT and AP. BDNF concentration was measured by enzyme-linked immunosorbent assay using the Emax Immunoassay System kit (Promega, Madison, WI, USA) according to the manufacturer's instructions.Log-linear analyses were used to examine the relationship between demographic characteristics, BDNF level, and clinical features and response status. The baseline BDNF levels and BDNF level increment were the best predictors of clinical outcome (OR1 = 3.358, P = 0.000; OR2 = 3.243, P = 0.000).The higher baseline BDNF levels and greater BDNF level increment were found to be associated with good outcome.

Abstract
BACKGROUND Sarcopenia is emerging as an important public health problem, and evidences have determined that poor sleep is associated with muscle strength, but the potential effects of excessive daytime sleepiness (EDS), snoring and witnessed apnea on handgrip strength have not been evaluated. AIM We aimed to examine the association between EDS, snoring, witnessed apnea and muscle strength in an adult population. DESIGN Cross-sectional study. METHODS This cross-sectional study comprised 19 434 adults. Handgrip strength was measured using a handheld digital dynamometer. EDS was assessed by Epworth Sleepiness Scale, snoring and witnessed apnea during sleep were reported through simple yes/no questions. Analysis of covariance was carried out to determine the association between EDS with snoring or witnessed apnea and muscle strength. RESULTS The means (95% confidence interval) for average handgrip strength/body weight (kg/kg) across symptoms categories were 0.396 (0.333-0.472), 0.393 (0.330-0.467), 0.396 (0.333-0.471) and 0.386 (0.325-0.460) (P < 0.0001), respectively. Similar results were observed with maximal handgrip strength/body weight (kg/kg). CONCLUSIONS Self-reported EDS accompanied with snoring or apnea is associated with lowest handgrip strength, independently of confounding factors. Whether improvement of EDS, snoring and apnea, can ameliorate age-associated decline in muscle strength warrants further studies.

Abstract
Objective: To investigate the role of microRNA-29b-3p (miRNA-29b-3p) and miRNA-34c-3p in the process of pulmonary fibrosis, we detected the expression levels of miRNA-29b-3p and miRNA-34c-3p in the lung tissue of rats exposed to silica and A549 cells. Methods: SPF male Wistar rats were randomly divided into 1, 7, 14, 21, 28 d control group and silica (SiO(2)) dusting group, with 6 rats in each group. One-time non-exposure method was used to infuse 1ml SiO(2) suspension. The rat SiO(2) dusting group was established in the liquid, and the control rats were intratracheally injected with 1 ml of sterile physiological saline in the same manner. The lung tissues of each group were collected at the corresponding time points after dusting. Three of the rats were taken out for pathological observation, and the other three were used to screen differentially expressed miRNAs in lung tissue by miRNA microarray technology. A549 cells were cultured at the in vitro cell level and divided into control group, SiO(2) stimulation group and TGF-β(1) stimulation group, and cells were collected at 12, 24 and 48 h after treatment. The expression levels of miRNA-29b-3p and miRNA-34c-3p in rat lung tissue and A549 cells were verified by real-time PCR (qRT-PCR), target gene prediction of miRNA-29b-3p and miRNA-34c-3p and perform GO enrichment analysis and KEGG pathway analysis. Results: The weight growth rate of the control group was significantly higher than that of the SiO(2) dusting group. Compared with the control group, the lung mass and lung coefficient of the SiO(2) dusting group were significantly increased (P<0.05). The inflammatory response of the lungs in the control group was significantly reduced at 21 and 28 days, and the inflammatory cells infiltrated in the lung tissue of the SiO2 group. The rats in the control group had a small amount of collagen at 21 and 28 days. A large amount of collagen fiber deposition began to appear in the lung tissue of rats exposed to SiO(2) for 21 days. Compared with the control group, the expression levels of miRNA-29b-3p and miRNA-34c-3p in the SiO(2) dusting group were significantly down-regulated, and there was significant difference compared with the control group (P<0.05). The expression levels of miRNA-29b-3p and miRNA-34c-3p in A549 cells treated with SiO(2) and human recombinant TGF-β1 were significantly lower than those in the control group at 24 h and 48 h, and the difference was statistically significant (P<0.05). Conclusion: Down-regulation of miRNA-29b-3p and miR-34c-3p in rat lung tissue A549 cells may be associated with the development of early silicosis and is expected to be an indicator of early silicosis diagnosis and prognosis.

Abstract
Objective: To screen the changes of microRNA (miRNA) expression profiles in lung tissues of early silicosis rats, and provide a basis for functional analysis of differential microRNA. Methods: SPF Wistar male rats were randomly divided into a negative control group and SiO(2)-exposed groups, with 30 rats in each group. The model of silicosis in rats was established by intratracheal instillation of 1 ml SiO(2) suspension, and the control rats were treated with 1mL in the same way to sterilize normal saline. The lung tissues of two group were collected at the 1, 7, 14, 21, 28 d after SiO(2)-exposed. Three of the rat lung tissues were used for pathological observation, and the other three were used to screen differentially expressed miRNAs in lung tissue by miRNA microarray technology. miRNA chip screening and RT-qPCR were used to verify the expression levels of miRNA-423-5p and miRNA-26a-5p in the two groups. miRNA-423-5p and miRNA-26a-5p are predicted by target genes and analyzed by GO (gene ontology) enrichment analysis and KEGG (kyoto encyclopedia of genes and genomes) pathway analysis. Results: In the control group, the inflammatory response of lung tissue 21 and 28 days was significantly reduced compared with 1, 7 and 14 days, and the inflammatory cells infiltrated in the lung tissue of the SiO(2)-exposed rats. The rats in the control group had a small amount of collagen at 21 and 28 days, but a large amount of collagen fiber deposition began to appear in the lung tissue of rats exposed to SiO(2) after 21 days. Compared with the control group, the expression levels of micro RNA-423-5p was significantly up-regulated and the expression of microRNA-26a-5p was significantly down-regulated in the SiO(2)-exposed rats lung tissues dust at different time points (P<0.05) . Conclusion: The up-regulation of miRNA-423-5p and the down-regulation of miRNA-26a-5p in lung tissues of early silicotic rats may be related to the occurrence and development of early silicosis.

Abstract
Objective: To observe the repairing effect of adipose mesenchymal stem cells (ADSCs) on lung injury induced by silica in rats. Methods: Primary ADSCs-GFP was obtained from rats. ADSCs-GFP was injected into tail vein of silicosis model rats. The expression of green fluorescence in lungs was observed regularly to determine the homing ability of ADSCs. Primary ADSCs of rats were obtained and randomly divided into control group, exposure group, vehicle group and ADSCs group. Silicosis rat model was established by non-exposed tracheal drip method. 24 hours after silica exposure, rats in ADSCs group were injected with ADSCs of 1×10(6)/kg body weight through tail vein, and the pathological changes of lung tissue were observed and evaluated 28 days after intervention. To explore the early intervention mechanism of ADSCs on pulmonary fibrosis in silicosis model rats, apoptosis-related proteins were detected by immunohistochemistry. Results: 28 days after exposure to silica, rats in the exposure group showed obvious pulmonary fibrosis. Compared with exposure group and vehicle group, ADSCs group showed less pulmonary inflammation, less silica nodules and less collagen deposition area. Immunohistochemical results showed that the expression of Caspase-3 and cytochrome C protein decreased and Bcl-2 protein increased after ADSCs transplantation. Conclusion: ADSCs infusion has an obvious intervention effect on postponing early silicosis fibrosis in rats exposed to silica, and its mechanism is related to the regulation of apoptotic process.

Abstract
BACKGROUND Burnout is a worked-related stress syndrome caused by long-term exposure to a stressful environment. Dysregulation of the hypothalamic- pituitary- adrenal (HPA) axis may be involved in both stress and burnout; an evaluation of genetic polymorphisms which alter activity in the HPA may be predictive of how likely an environment is to produce burnout. METHODS Using a cross-sectional design, this study examined whether corticotrophin-releasing hormone receptor 1 (CRHR1) gene polymorphism rs110402 is a risk factor for burnout; further, it explores whether the interaction of stress × CRHR1 gene predicts burnout in the healthcare workers in a Chinese Han population. House and Rizzo's work stress scale, Sources of Pressure Scale and Maslach Burnout Inventory-General Survey were administered to 712 participants from a large general hospital in Beijing. The CRHR1 rs110402 polymorphism was genotyped in 376 participants. RESULTS Our results showed significant positive inter-correlations between stressor, work stress and depressive scores (all p < 0.001) with only one exception. Males, younger age and higher educational level were associated with burnout (all p < 0.05). The presence of the CRHR1 rs110402 genotype was not correlated with the presence of job stress or burnout. However, we found statistically significant interaction between CRHR1 rs110402 and job stress on burnout (p < 0.05). Individuals homozygous for the A allele reported significantly higher emotional exhaustion than G allele carriers in the high stress group. LIMITATIONS The sample was only chosen from the medical professions, and the sample size was relatively small. Only one polymorphism in CRHR1 gene was analyzed, while only about half of the total individuals were genotyped. CONCLUSIONS Our results suggest a close relationship between work-related stress and burnout and that the A allele of the CRHR1 rs110402 polymorphism may enhance feelings of emotional exhaustion when experiencing work-related stress.

Abstract
UNLABELLED Rehmanniae Radix Preparata (RRP) improves bone quality in OVX rats through the regulation of bone homeostasis via increasing osteoblastogenesis and decreasing osteoclastogenesis, suggesting it has a potential for the development of new anti-osteoporotic drugs. INTRODUCTION Determine the anti-osteoporotic effect of RRP in ovariectomized (OVX) rats and identify the signaling pathway involved in this process. METHODS OVX rats were treated with RRP aqueous extract for 14 weeks. The serum levels of tartrate-resistant acid phosphatase (TRAP), receptor activator of nuclear factor kappa-Β ligand (RANKL), alkaline phosphatase (ALP), and osteoprotegerin (OPG) were determined by ELISA. Bone histopathological alterations were evaluated by H&E, Alizarin red S, and Safranin O staining. Bone mineral density (BMD) and bone microstructure in rat femurs and lumbar bones were determined by dual-energy X-ray absorptiometry and micro-computed tomography. Femoral bone strength was detected by a three-point bending assay. The expression of Phospho-glycogen synthase kinase 3 beta (p-GSK-3β), GSK-3β, Dickkopf-related protein 1 (DKK1), cathepsin K, OPG, RANKL, IGF-1, Runx2, β-catenin, and p-β-catenin was determined by western blot and/or immunohistochemical staining. RESULTS Treatment of OVX rats with RRP aqueous extract rebuilt bone homeostasis demonstrated by increasing the levels of OPG as well as decreasing the levels of TRAP, RANKL, and ALP in serum. Furthermore, RRP treatment preserved BMD and mechanical strength by increasing cortical bone thickness and epiphyseal thickness as well as improving trabecular distribution in the femurs of OVX rats. In addition, RRP downregulated the expression of DKK1, sclerostin, RANKL, cathepsin K, and the ratio of p-β-catenin to β-catenin, along with upregulating the expression of IGF-1, β-catenin, and Runx2 and the ratio of p-GSK-3β to GSK-3β in the tibias and femurs of OVX rats. Echinacoside, jionoside A1/A2, acetoside, isoacetoside, jionoside B1, and jionoside B2 were identified in the RRP aqueous extract. CONCLUSION RRP attenuates bone loss and improves bone quality in OVX rats partly through its regulation of the canonical Wnt/β-catenin signaling pathway, suggesting that RRP has the potential to provide a new source of anti-osteoporotic drugs.

Abstract
Objective: To observe serum levels of periostin, ECP, IgE in the antibiotic enterprise workers, and study the role of periostin, ECP, IgE in the development of allergic inflammation. Methods: 90 cases with asthma or rhinitis were enrolled as disease group, another 117 workers exposed to 7-ACA、6-APA dust without suffering from allergic illness, are chosen as group of dust exposed, and 192 healthy workers who didn't contact dust were chosen as control group. Questionnaires were used to learn their basic information.Lung function was determined with a portable spirometer.The expression levels of periostin、ECP and IgE in serum were measured by enzyme-linked immuno sorbent assay. Results: The exposure group and disease group had significantly lower forced vital capacity (FVC) , forced expiratory volume in 1 second (FEV(l.0)) , and FEV(l.0)/FVC ratio than the control group (P<0.05) . The disease group had significantly higher eosinophil than the control group (P<0.05) . Compared with the control group, the exposure group, the disease group, asthma subgroup, rhinitis subgroup of serum periostin and IgE increased, the differences are statistically significant (P<0.05) . Serum levels of ECP in the workers of asthma subgroup were significantly higher than that in control group (P<0.05) . Serum expression levels of periostin were positively correlated with IgE, ECP in workers (P<0.001) , serum levels of periostin were negatively correlated with FEV(1.0) in workers (P<0.05) . Multiple logistics regression analysis found that exposure to 7-ACA or 6-APA (OR=3.09, 95%CI: 1.83-5.21) , age>47years (OR=2.53, 95%CI: 1.22-5.26) , higher ECP (OR=1.04, 95%CI: 1.01-1.06) were risk factors for increased serum periostin level. Conclusion: Occupational exposure to 7-ACA or 6-APA can result in higher serum periostin level, exposure to 7-ACA or 6-APA, age>47 years, higher ECP are risk factors for increased serum periostin level.

Abstract
Antipsychotic pharmacotherapy is strongly obesogenic and is associated with increased oxidative stress in patients with schizophrenia. However, whether these changes reflect psychopathology, antipsychotic efficacy, or some other factor is not known. Our study aims to investigate the degree of oxidative stress in different BMI categories and to identify clinical symptomatology that may be paired with increased oxidative stress in a schizophrenia population. To this end, we performed a cross-sectional study and recruited 89 long-term inpatients with schizophrenia and collected the following variables: plasma malondialdehyde (MDA), superoxide dismutase (SOD), catalase (CAT), and glutathione peroxidase (GPx), routine biochemical analysis, and psychopathology through the Positive and Negative Syndrome Scale (PANSS). The results indicate that the levels of the lipid peroxidation product, MDA, were significantly higher in the high BMI group than the low (normal) BMI group. As expected, high BMI was associated with an atherogenic lipid profile; however, it was also associated with fewer psychopathological symptoms. Multiple regression analysis found that MDA levels, the PANSS general psychopathology subscore, and triglyceride levels (all p < 0.05) were independent contributors to the BMI in patients. These results suggested that oxidative stress may play an important role in antipsychotic-induced weight gain. Further investigations using the longitudinal design in first-episode schizophrenia patients are needed to explore the beneficial effect of antioxidants on the abnormal lipid metabolism mediated by antipsychotic treatment.

Abstract
BACKGROUND The prognostic significance of misfolded α-synuclein (α-Syn) aggregates in Parkinson's disease (PD) has not been well investigated. The aim of this study was to reveal the relationship between misfolded α-Syn aggregate concentration in cerebrospinal fluid (CSF) and cognitive decline risk in PD. METHODS A total of 278 patients with PD were retrospectively included. They were diagnosed between 2011 and 2013. The end-point was 2016, and the follow-up period was 54.3 ± 10.0 months. Cognitive decline was defined as a 4-point decrease in the Mini-Mental State Examination score during follow-up. Misfolded α-Syn aggregate concentration in baseline CSF was measured using the protein misfolding cyclic amplification (PMCA) technique. Time to reach 50% of the maximum fluorescence value was recorded. RESULTS The PMCA technique successfully detected the level of misfolded α-Syn aggregates in CSF with a sensitivity of 85.3% and a specificity of 91.4%. The time to reach 50% of the maximum fluorescence value was shorter in the patients with cognitive decline than in the patients without cognitive decline (190.7 ± 40.1 h vs. 240.8 ± 45.6 h, P < 0.001). Multifactorial Cox regression analysis revealed that reaching 50% of the maximum fluorescence value in ≤219 h at baseline was associated with increased risk of cognitive decline during the follow-up (HR: 4.90, 95% CI: 2.75-8.74, P < 0.001). CONCLUSION Baseline concentration of misfolded α-Syn aggregates in CSF measured by the PMCA technique predicts risk of cognitive decline in PD.
