Abstract
Objective: To investigate the influencing factors for depression among workers in a petrochemical enterprise and the association of occupational stress and occupational environment with depression, and to provide a scientific basis for the improvement of mental health and the prevention and treatment of depression among workers in petrochemical enterprises. Methods: A cross-sectional study was performed in March 2018, and cluster sampling was used to select 1888 workers from a petrochemical enterprise in Liaoning Province, China for a questionnaire survey. A total of 1888 questionnaires were collected, among which there were 1521 usable questionnaires, with an effective recovery rate of 80.56%. The general status of the workers in this petrochemical enterprise was investigated, and Center for Epidemiologic Studies Depression Scale (CES-D) , Effort-Reward Imbalance (ERI) , and Perceived Work Environment (PWE) were used to evaluate depression, occupational stress, and occupational environment. Constituent ratio was used to describe the distribution of different demographic features, work conditions, and lifestyles among the workers in this petrochemical enterprise. One-way analysis of variance and the t-test were used to compare the scores of depressive tendency between the workers with different features. Pearson correlation analysis was used to investigate the correlation of occupational stress and occupational environment with depression. Multivariate hierarchical regression analysis was used to investigate the influencing factors for depression. Results: The score of depression tendency was 18.94±9.21 in the workers in this petrochemical enterprise, and the incidence rate of depression symptoms was 59.8% (909/1521) . The workers who were aged <35 years, lived alone or in widowhood, or had an income of ≤4000 yuan tended to have a high score of depression tendency. And ordinary workers, oil-refining workers, workers with night shift and non-fixed shift, and workers with a lack of physical exercise and low sleep quality tended to have a high score of depression tendency (P<0.05) . The dimensions of extrinsic and intrinsic efforts of occupational stress and severity of occupational environment were positively correlated with depression (r=0.254, 0.242, 0.274, P<0.01) . And the dimension of reward was negatively correlated with depression (r=-0.348, P<0.01) . The multivariate hierarchical regression analysis showed that occupational stress and occupational environment had a marked predictive effects on depression, with an explained variance of 18.4% and 12.1%, respectively. Conclusion: There is a high level of depression tendency among workers in petrochemical enterprises, and demographic features, work conditions, lifestyle, occupational stressors, and occupational environment factors are influencing factors for depression.

Abstract
Objective: To understand the HIV antibody screening results among the preoperative examination patients in Beijing Tongren Hospital from 2008 to 2018. Methods: A retrospective analysis of the HIV antibody screening data of thepreoperative examination patients from 2008 to 2018 in Beijing Tongren Hospital was performed with software SPSS19.0. Trend chi-square was used to analyze the positive rate, age, marital status, household registration and so on. Results: Among the 750 013 clinical patients, 428 (0.057%) cases were screened anti-HIV positive and 370(0.049%) cases were confirmed anti-HIV positive when detected with western blotting.Most of the HIV-infectedindividuals were non-Beijing nationality, accounting for 60.27%.Among the 370 HIV-infected patients, there were 334 males (90.27%) and 36 females (9.73%). The age was distributed mainly between 20-40 years old (62.43%), secondly between 40-60 years old (28.65%).361 (97.57%)HIV-infected cases were transmitted by the sex and the MSM men increased from 2008 to 2018 (trend χ²=7.307, P=0.007). There were 22 cases (5.95%) with HBsAg positive, 11 cases (2.97%) with anti-HCV positive. Among the 159 HIV-positive patients (42.97%) companied with syphilis specific antibody positive, there were 64 cases (17.30%) with TRUST tests positive. Additionally, 178 (48.11%) HIV-infected patientsfirst visited doctors because of ocular disease in the hospital; secondly, 71 (19.19%) HIV-infected patientsfirst visited the dermatology. Conclusions: The number of HIV-infected patientsmarkedly increased from 2008 to 2018. The sexual transmission is still the main pathway for HIV infection, particularly homosexual transmission. Moreover, the results indicate that it is necessary to detect HIV antibody for the ocular disease patients.

Abstract
Photoreceptors, especially cones, which are enriched in the human macula, have high energy demands, making them vulnerable to metabolic stress. Metabolic dysfunction of photoreceptors and their supporting retinal pigment epithelium (RPE) is an important underlying cause of degenerative retinal diseases. However, how cones and the macula support their exorbitant metabolic demand and communicate with RPE is unclear. By profiling metabolite uptake and release and analyzing metabolic genes, we have found cone-rich retinas and human macula share specific metabolic features with upregulated pathways in pyruvate metabolism, mitochondrial TCA cycle, and lipid synthesis. Human neural retina and RPE have distinct but complementary metabolic features. Retinal metabolism centers on NADH production and neurotransmitter biosynthesis. The retina needs aspartate to sustain its aerobic glycolysis and mitochondrial metabolism. RPE metabolism is directed toward NADPH production and biosynthesis of acetyl-rich metabolites, serine, and others. RPE consumes multiple nutrients, including proline, to produce metabolites for the retina.

Abstract
BACKGROUND Oxidative stress plays an important role in initiating the destruction of melanocytes, which could be one possible mechanism of vitiligo. PINK1 is an outer membrane protein of mitochondria, which protects many cells from oxidative stress through regulating mitochondrial function. However, the role of PINK1 and its effects on oxidative damage in melanocytes have not been elucidated. AIM To investigate the expression and effects of PINK1 on oxidative stress in human melanocytes. METHODS Quantitative reverse transcription-PCR and western blot analysis were used to analyse the expression of PINK1 in PIG1 melanocyte and gene downregulation models. Levels of cell viability, cell apoptosis and intracellular reactive oxygen species (ROS), mitochondrial morphology, mitochondrial membrane potential (MMP) and mitochondrial permeability transition pore (MPTP) opening were measured in PIG1 models transfected with PINK1 small interfering RNA with or without hydrogen peroxide (H2 O2 ). RESULTS We first observed the expression of PINK1 in human PIG1 melanocytes and found that downregulation of PINK1 made melanocytes more sensitive to oxidative stress induced by H2 O2 , with more cell apoptosis and increased intracellular ROS. Meanwhile, downregulation of PINK1 caused morphological changes in mitochondria, decreased the MMP and increased MPTP opening. CONCLUSIONS Our study found PINK1 plays an essential role in protecting human melanocytes from oxidative stress.

Abstract
A new trans-4-hydroxy-l-proline (trans-Hyp) producing Bacillus cereus HBL-AI, was isolated from the air, which was screened just using l-proline as carbon and energy sources. This strain exhibited 73·4% bioconversion rate from initial l-proline (3 g l-1 ) to trans-Hyp. By sequencing the genome of this bacterium, 6244 coding sequences were obtained. Genome annotation analysis and functional expression were used to identify the proline-4-hydroxylase (BP4H) in HBL-AI. This enzyme belonged to a family of 2-oxoglutarate-related dioxygenases, which required 2-oxoglutarate and O2 as co-substrates for the reaction. Homologous modelling indicated that the enzyme had two monomers and contained conserved motifs, which included a distorted 'jelly roll' β strand core and the residues (HXDXnH and RXS). The engineering Escherichia coli 3 Δ W3110/pTrc99a-proba-bp4h was constructed using BP4H, which transformed glucose to trans-Hyp in one step with high concentration of 46·2 g l-1 . This strategy provides a green and efficient method for synthesis of trans-Hyp and thus has a great potential in industrial application.

Abstract
OBJECTIVE We aimed to explore the role of microRNA-449b-5p in osteogenic differentiation of bone marrow mesenchymal stem cells (BMSCs) and its mechanism of action. MATERIALS AND METHODS Quantitative Real Time-Polymerase Chain Reaction (qRT-PCR) assay was used to detect the expression levels of microRNA-449b-5p and osteogenic markers including RUNX2, OCN during BMSCs differentiation. The microRNA-449b-5p mimic and microRNA-449b-5p inhibitors were transfected into BMSCs to achieve microRNA-449b-5p overexpression and knockdown, then the expressions of osteogenic markers were detected by qRT-PCR. The ALP activity staining and the alizarin red staining were used to detect the activity of ALP and the mineralization ability of cells after overexpression and knockdown of microRNA-449b-5p. Binding sites for microRNA-449b-5p and Satb2 were predicted by TargetScan, the PicTar and microRNAanda programs, and confirmed by dual-luciferase reporter gene assay. The relationship between microRNA-449b-5p and Satb2 was analyzed by QRT-PCR and Western blot. The microRNA-449b-5p inhibitor and shSATB2 lentivirus were simultaneously transfected in BMSCs, and the expression levels of RUNX2, OCN and ALP were detected by qRT-PCR and ALP activity assays. RESULTS microRNA-449b-5p expression gradually decreased during osteogenic differentiation. Overexpression of microRNA-449b-5p inhibited BMSCs differentiation by down-regulating ALP activity, RUNX2, and OCN expression, while the opposite result was observed after knockdown of microRNA-449b-5p. MicroRNA-449b-5p can bind to the 3'UTR end of Satb2, which was involved in the osteogenic differentiation of microRNA-449b-5p-regulated BMSCs, and silencing of Satb2 can abolish the positive effect of the microRNA-449b-5p inhibitor on osteoblasts differentiation. CONCLUSIONS microRNA-449b-5p could aggravate osteoporosis by inhibiting osteogenic differentiation of BMSCs through targeting Satb2.

Abstract
OBJECTIVE Many studies have emphasized the function of microRNA-296 (miR-296) that inhibits tumor formation. To some extent, the role of miR-296 in esophageal squamous cell carcinoma (ESCC) remains misleading. Therefore, the current research was designed to investigate the regulatory mechanisms of miR-296 and signal transducer and activator of transcription 3 (STAT3) in ESCC. PATIENTS AND METHODS The mRNA expression of miR-296-5p and STAT3 in ESCC tissues or cell lines was measured via quantitative Real Time-Polymerase Chain Reaction (qRT-PCR). The protein level of STAT3 was measured by Western blotting assay. The Luciferase reporter assay was used to verify the binding sites between miR-296-5p and STAT3. The transwell assay was employed to identify cell migration and invasion. RESULTS Down-regulation of miR-296-5p was detected in ESCC tissues and cell lines (p<0.01). Additionally, miR-296-5p was found to target STAT3 directly. Functionally, up-regulation of miR-296-5p or down-regulation of STAT3 significantly inhibited cell migration and invasion in ESCC. CONCLUSIONS MiR-296-5p inhibited cell invasion and migration in ESCC by downregulating STAT3. The overexpression of miR-296-5p by targeting STAT3 suppressed tumorigenesis of ESCC cells.

Abstract
OBJECTIVE Triple negative breast cancer is typically characterized by high malignancy, easy recurrence and metastasis, and poor prognosis. However, effective treatment for triple negative breast cancer has not yet been identified. Our research explores the underlying mechanisms of exosomes in transporting Let-7a and regulating c-Myc gene and their roles in the development of triple negative breast cancer, and to provide new ideas for targeted therapy of triple negative breast cancer. PATIENTS AND METHODS Based on previous studies that focused on the roles of c-Myc and Let-7a in the development of triple negative breast cancer, triple negative breast cancer cell lines have been constructed by c-Myc knockout and overexpression of Let-7a, respectively, to evaluate the effects of c-Myc, and Let-7a, as well as exosomes transmitting Let-7a on the development of triple negative breast cancer. RESULTS Let-7a, which is mediated by exosomes, inhibited proliferation, migration, and invasion of MDA-MB-231 cells by binding on the 3'UTR region of the c-Myc gene and silencing of the c-Myc expression. CONCLUSIONS Our study revealed the role of c-Myc, Let-7a, and exosomes in the development of triple negative breast cancer, which lay the theoretical foundation for further usage of exosomes to construct tumor killing vectors and for exploring specific targets for triple negative breast cancer.

Abstract
OBJECTIVE Recent researches have revealed the role of long noncoding RNAs (lncRNAs) in the development of tumors. In this study, lncRNA LUCAT1 was explored to identify how it affected the progression of cervical cancer. PATIENTS AND METHODS Quantitative Real-time polymerase chain reaction (qRT-PCR) was used to detect LUCAT1 expression in both cervical cancer cells and tissue samples. Moreover, the associations between LUCAT1 expression level and patients' overall survival rate were explored, respectively. In addition, cell proliferation assay and transwell assay were conducted. Furthermore, the underlying mechanism was explored via performing qRT-PCR and Western blot assay. RESULTS By comparing with the expression level in corresponding ones, the LUCAT1 expression level in cervical cancer samples was significantly higher. Moreover, expression level of LUCAT1 was negatively correlated with patients' overall survival time. In addition, after LUCAT1 was overexpressed, cell proliferation, cell invasion and migration capacities were promoted in vitro. In addition, the mRNA and protein expressions of MTA1 were upregulated after LUCAT1 was overexpressed. Furthermore, it was found that the expression level of MTA1 was positively related to LUCAT1 expression level in cervical cancer tissues. CONCLUSIONS We showed that LUCAT1 could enhance proliferation, invasion and migration of cervical cancer cells through upregulating MTA1, which might offer a potential therapeutic choice for patients with cervical cancer.

Abstract
Mitochondrial respiration in mammalian cells not only generates ATP to meet their own energy needs but also couples with biosynthetic pathways to produce metabolites that can be exported to support neighboring cells. However, how defects in mitochondrial respiration influence these biosynthetic and exporting pathways remains poorly understood. Mitochondrial dysfunction in retinal pigment epithelium (RPE) cells is an emerging contributor to the death of their neighboring photoreceptors in degenerative retinal diseases including age-related macular degeneration. In this study, we used targeted-metabolomics and 13C tracing to investigate how inhibition of mitochondrial respiration influences the intracellular and extracellular metabolome. We found inhibition of mitochondrial respiration strikingly influenced both the intracellular and extracellular metabolome in primary RPE cells. Intriguingly, the extracellular metabolic changes sensitively reflected the intracellular changes. These changes included substantially enhanced glucose consumption and lactate production; reduced release of pyruvate, citrate, and ketone bodies; and massive accumulation of multiple amino acids and nucleosides. In conclusion, these findings reveal a metabolic signature of nutrient consumption and release in mitochondrial dysfunction in RPE cells. Testing medium metabolites provides a sensitive and noninvasive method to assess mitochondrial function in nutrient utilization and transport.

Abstract
OBJECTIVE The aim of this study was to investigate the role of dexmedetomidine (Dex) in lactate signaling cascade and myocardial ischemia/reperfusion (I/R) injury in mice. MATERIALS AND METHODS The left anterior descending of the coronary artery was ligatured for 30 min and then reperfused for 6 h to induce myocardial I/R injury in mice. Heart samples were collected and the levels of lactate, SOD and MDA were measured. Infarct size and myocardium were stained with triphenyltetrazolium chloride and TUNEL, respectively. In addition, the expression levels of MCT1, cytochrome c, cleaved caspase-9 and -3 were detected by Western blot. RESULTS The myocardial infarct size, lactate and MDA levels of the I/R group were significantly increased, whereas the SOD activity was decreased. However, Dex significantly reduced the myocardial infarct size, as well as lactate and MDA levels in contrast to the I/R group. Meanwhile, the SOD activity was remarkably increased. The expression levels of MCT1, cytochrome c, cleaved caspase-9 and -3 were significantly increased in the I/R group. In addition, Dex administration further increased the expression of MCT1, whereas decreased the expressions of cytochrome c, cleaved caspase-9 and -3 in contrast to the I/R group. CONCLUSIONS Dex elevated the expression of mitochondrial MCT1 and inhibited oxidative stress and the activation of mitochondria-dependent apoptosis in mice. This indicated that Dex attenuated myocardial I/R injury by regulating lactate signaling cascade.

Abstract
PURPOSE Eyelid basal cell carcinoma (BCC) is the most common eyelid malignancy. Metabolic reprogramming is critical in tumorigenesis, but the metabolic feature of eyelid BCC remains elusive. In this study, we aim to reveal the metabolic profile in eyelid BCC using targeted metabolomics. Eyelid samples were collected from patients who had removal of BCC and from control patients who underwent blepharoplasty. Multivariate analysis of metabolomics data distinguished the two groups, indicating that eyelid BCC has significantly different metabolome than the healthy tissue. We found 16 increased and 11 decreased metabolites in the BCC tissues. These metabolites were highly enriched in the metabolism of nicotinamide adenine dinucleotide (NAD), glutathione metabolism, polyamine metabolism, and the metabolism of glycine, serine, threonine, arginine and proline. amino acid metabolism. Metabolites from NAD metabolism (Nicotinamide; Nicotinamide riboside; N1-Methylnicotinamide) had the highest sensitivity, specificity, and prediction accuracy in a prediction model for eyelid BCC. In conclusion, eyelid BCC has a signature change of cell metabolome. Metabolites in NAD metabolic pathways could potentially be biomarkers or therapeutic targets for eyelid BCC.

Abstract
Objective: To analyze clinical characteristics of intracranial vessel involvement in Takayasu's arteritis (TA). Methods: Retrospectively analyzed 135 hospitalized TA patients' clinical data in Beijing Anzhen Hospital from November 2012 to November 2018. Based on intracranial artery (IA) complicated or not, TA patients were divided into two groups:32 patients within involvement and 103 patients without involvement. The difference in comparison of imaging types, basic data and laboratory test were analyzed. Results: The proportion of TA patients with intracranial vascular involvement was 23.7% (32/135) and the most common site was internal carotid artery (intracranial segment) (59.4%, 19/32). The incidences of hypertension and coronary heart disease were significantly higher in TA patients with intracranial vascular involvement compared with the patients without intracranial involvement (46.9% vs 26.2%, 21.9% vs 6.8%, χ(2)=4.863, 4.460, all P<0.05). The rate of tocilizumab treatment in the intracranial vascular involved group was higher than that in the group without intracranial vascular involvement (40.6% vs 19.4%, χ(2)=5.945, P<0.05). The platelet count in patients with intracranial involvement group was significantly lower than that in patients without intracranial involvement group [(218±55)×10(9)/L vs (272±71)×10(9)/L, t=-3.570, P<0.01], while the hemoglobin [(130±17) vs (121±18) g/L, t=2.363, P<0.05] and triglyceride [1.22(0.75, 1.64) vs 0.92(0.63, 1.21) mmol/L, U=1 017.000, P<0.01] were significantly higher than those without intracranial vascular involvement. Moreover, coronary artery involvement presented more frequently in the intracranial vascular involved group than the group without intracranial vascular involvement (43.8% vs 14.6%, χ(2)=12.331, P<0.01). Logistic regression analysis showed that the incidence of intracranial vascular disease in TA patients with coronary artery involvement was 4 times higher than that in patients without coronary artery lesions (OR=3.965, 95%CI:1.584-9.926, P=0.003). Conclusion: The proportion of intracranial vascular involvement in TA is not rare, TA patients with cardiovascular risk factors should be considered to strengthen imaging examination of intracranial vessels.

Abstract
Objective: To compare the clinical application effect of totally implantable venous access ports (TIVAP) via the internal jugular vein,the subclavian vein and the brachiocephalic veins under the guidance of ultrasound combined with DSA. Methods: The clinical materials of 346 patients (162 males and 184 females) who implanted TIVAP in intervention Department of Jiangsu Cancer Hospital between August 2018 and January 2019 were retrospectively reviewed and the average age was (57±12) years (17 to 83 years). The patients were divided into three groups according to the different implantation approaches. One hundred and twenty-six patients (67 males and 59 females) were group A who implanted from the internal jugular vein and the average age was (52±11) years,114 patients (52 males and 62 females) were group B who implanted from the subclavian vein and the average age was (58±10) years,106 patients (43 males and 63 females) were group C who implanted from the brachiocephalic vein and the average age was (60±9) years.The first-puncture success rate,operating time,implanting length,intraoperative pain score, one month comfort rating after surgery, unscheduled decannulation rates, early and late complication rates were compared among three groups. Results: All the patients implanted the TIVAP successfully.There were no significant differences about the first-puncture success rate (χ(2)=1.375,P=0.503),operating time (F=0.968, P=0.624), unscheduled decannulation rates (χ(2)=1.570, P=0.456), and the total pipe length among the three groups (F=0.821, P=0.441),while the catheter length inside the blood vessel were the shortest in group C (F= 263.618, P=0.000), and the one month comfort rating after surgery of group C were higher compared with group A and B (F=52.248,P=0.000).Pitch-off syndrome was a unique complication of group B (χ(2)=6.159,P=0.046) and other complications were no significant differences (P>0.05). Conclusion: There are high accuracy and safety among three implantation approaches,and the approach via brachiocephalic vein under the guidance of ultrasound combined with DSA is more comfortable and lower complication rates, which could be priority to choose.

Abstract
IntroductionIndividuals with co-occurring disorders have higher levels of psychological distress and poorer psychosocial functioning, as compared with individuals with substance dependence only. Studies identified substance abuse as a risk factor, which increases the likelihood that an individual with mental disorders may become violent.ObjectivesTo examine the gender differences in drug-related problems and predictors of recidivism among a sample of 1,444 offenders with co-morbid drug abuse and mental disorders participating in California's Proposition 36.MethodsCharacteristics and problem severity in multiple key life areas were assessed at intake using Addiction Severity Index, and drug treatment participation, mental health diagnoses and arrests were based on official records.ResultsWomen demonstrated greater problem severity than men in family relationships, health, psychological health, and sexual and physical abuse history. Men on the other hand had greater criminal history, high rates of attention disorder, and psychotic disorder. Logistic regression analyses showing that for the combined sample, male, young age, cocaine use (relative to methamphetamine), drug abuse severity, methadone treatment, arrest history and fewer prior treatment history were associated with higher recidivism at 12-month follow-up; lower education, cocaine use, and arrest history were related to women's recidivism, while young age, outpatient treatment, and arrest history were predictors of men's recidivism.ConclusionsAlthough the specific type of mental disorder did not seem to be predictive of recidivism, the high rates of mental health disorder and arrest of this population is problematic. Intervention strategies taking into consideration gender-specific problems and needs can improve outcomes for both.
