Abstract
We evaluated the association between macrophage polarization and the development of pleural thickening in patients with tuberculous pleurisy. Patients with tuberculous pleurisy admitted to our hospital between October 2018 and March 2019 were prospectively recruited. Pleural fluid samples were obtained before treatment for detection of adenosine deaminase (ADA) and macrophage phenotype (M1: CD14+ CD86+; M2: CD14+ CD163+). Peripheral blood samples were subjected to interferon gamma release assay (IGRA). All subjects were administered standard anti-tuberculosis regimen (2HREZ/4HR); high-resolution CT was performed to determine pleural thickening (thickness>2mm) after completion of treatment. Pleural effusion in patients with thickened pleura had significantly more M1 but fewer M2 macrophages, and higher ADA level, as compared to those with normal pleura (P<0.05). No significant between-group difference was observed with respect to IGRA. In receiver operating characteristic (ROC) curve analysis, the optimal cut-off level of M1/M2 ratio for predicting pleural thickening was 1.149 (area under the curve: 0.842; sensitivity: 88.6%; specificity: 69.2%; positive predictive value: 86.3%; negative predictive value: 81.7%). M1/M2 ratio in the pleural fluid is a promising marker for predicting the development of pleural thickening in patients with tuberculous pleurisy. Macrophage-mediated immune response may play an important role in the pathogenesis of tuberculous pleurisy.

Abstract
Abstract
Study question
What is the potential function of Acylglycerol Kinase (AGK) in the pathogenesis of preeclampsia(PE).
Summary answer
AGK plays an important role in the pathogenesis of PE by influencing the function of the trophoblast cells.
What is known already
PE is the leading cause of maternal and perinatal mortality and morbidity. The underlying mechanism is still not completely elucidated. Disorder migration, invasion and mitochondria function of trophoblast cells are one of mechanism in preeclampsia. AGK is a subunit of the mitochondrial channel protein complex TIM22, and maintain the stability of mitochondrial structure and function. Studies have shown that AGK is related to the development of various cancers by infecting the cells migration and invasion. It will be interesting to explore the potential function of AGK in the process of early trophoblast development and the pathogenesis of PE.
Study design, size, duration
Firstly, explore the expression of AGK in PE. Secondly, lentivirus systems was used to generate loss and gain of function models in trophoblast cell line-HTR8/Sneov to study the role of AGK in the pathogenesis of PE.
Participants/materials, setting, methods
We examined the expression of AGK both in placental tissues from PE patients and normal pregnant patients. Meanwhile, we generated AGK loss and gain of function models in HTR8/Sneov cells by using lentivirus systems. Transwell assays, scratch-wound assays, EDU and plate clone formation assays, cell apoptosis assays, cell cycle assays, ATP concentration, mtDNA level and transmission electron microscopy were used to examine the function of AGK in HTR8/Sneov cells model.
Main results and the role of chance
In this study, AGK was significantly decreased in the extra-villous trophoblast (EVT) cells in placental tissues of PE patients compared with that in control group by immunohistochemistry. And further confirmed the expression of AGK in placental tissues by QPCR, western blot. We demonstrated that knockdown of AGK in HTR8 dramatically decreased the cell proliferation, migration and invasion. It also showed the significantly lower plate clone formation rate in AGK knockdown -HTR8 cells compare with the WT HTR8 cells. While overexpression of AGK in HTR8 dramatically increased the cell proliferation, migration, invasion and higher plate clone formation rate. Further, we demonstrated that AGK regulated the ATP level and mtDNA level in HTR8 cells model. And we found that knockdown AGK decreased the number of mitochondria, and shown the mitochondrial crista disorder, mitochondrial swelling and dissolution and mitochondrial membrane fragmentation. While overexpression AGK increased the number of mitochondria.
Limitations, reasons for caution
Although we show that AGK played an important role in the function of HTR8, the study of working mechanism of AGK in PE is still very limited. More studies will be performed to explore its underline mechanism.
Wider implications of the findings: This study was the first time to explore the role of AGK in PE. It will help us to better understand the pathogenesis of PE, which might be helpful in future application of novel therapeutic targets in PE.

Abstract
Objective: To establish a multi-state Markov model of type 2 diabetes mellitus (T2DM) patients and explore the transition rule between the cumulative number of different chronic complications, estimate the transition probability and intensity between status, and explore the possible factors affecting the transition between status. Methods: A retrospective cohort study of 33 575 patients with T2DM was conducted. According to the baseline and the cumulative number of chronic complications during the follow-up period, the patients were classified based on five status: T2DM, one complication, two complications, three complications, four and above complication, indicated by S0, S1, S2, S3 and S4, respectively. A time-continuous and state-discrete multi-state irreversible Markov model was used for statistical analysis. Results: The study included 33 575 T2DM patients, and their average age was 60 years old, the median of follow-up length was 8 years. In these patients, 32 653 had no baseline complications. At the end of follow-up, the transition probabilities of S0→S1, S1→S2, S2→S3 and S3→S4 were 16.4%, 32.4%, 45.6% and 25.9%, respectively. The results of multivariate analysis showed that being female (HR=0.919), less than 60 years old (HR=0.929), higher fasting plasma glucose (HR=1.601), lower high-density lipoprotein (HR=1.087), higher total cholesterol (HR=1.090),weekly exercise (HR=0.897), vegetarian diet (HR=0.852) and heavy diet (HR=1.887) were the risk factors for S0 to S1. And being female (HR=0.768), less than 60 years old (HR=0.859) and lower high-density lipoprotein (HR=1.160) were the risk factors for S1 to S2. Conclusions: The probability of multiple complications in T2DM patients increased over time, the transition intensity of S2→S3 was largest, followed by S1→S2. Therefore, we need to conduct both early and long-term indicators monitoring and disease prevention, strengthen the health education to improve patients' daily living habits at early stage of the illness, encourage patients to have moderate exercise and balanced diet, strengthen the monitoring of fasting blood- glucose, cholesterol and high-density lipoprotein levels to prevent the deterioration of the illness.

Abstract
OBJECTIVE To investigate the expression of nicotinamide-N-methyltransferase (NNMT) in gastric cancer (GC) and explore its biological and clinicopathological significance. OBJECTIVE We screened the candidate genes associated with the classification and prognosis of gastric cancer by analyzing GEO, Oncomine and TCGA datasets. The molecular pathways and protein interaction network involving these candidate genes were analyzed using STRING, GSEA, David and Cytoscape software. The expressions of the candidate genes in 28 pairs of gastric cancer and adjacent tissues were detected with qRTPCR, and CCK-8 assay, clone formation assay, wound healing assay and Transwell assay were carried out to analyze the effects of modulation of NNMT expression on proliferation, invasion and migration of different gastric cancer cell lines. OBJECTIVE NNMT was highly expressed in gastric cancer tissues and was negatively correlated with the prognosis of patients with gastric cancer. Pathway analysis showed that the high expression of NNMT was associated with adhesion-related pathway molecules such as extracellular matrix receptors, cell adhesion molecules, and cytokine receptors, while its low expression was associated with base mismatch repair and riboflavin metabolism. Protein interaction analysis showed that NNMT interacted with 16 differentially expressed proteins such as AURKA and was co-expressed with TAGLN, PTRF, AKAP12 and IGF2BP2. In clinical tissue specimens, qRT-PCR results showed that the expression of NNMT mRNA was significantly higher in gastric cancer tissues than in the adjacent tissues (P < 0.05). In gastric cancer cell lines, overexpression of NNMT was found to significantly promote cell proliferation, invasion and migration, while NNMT knockdown produced obvious inhibitory effects on cell proliferation, invasion and migration. OBJECTIVE NNMT is highly expressed in gastric cancer and negatively correlated with the prognosis of gastric cancer patients. The high expression of NNMT promotes the proliferation, invasion and metastasis of gastric cancer cells, suggesting the potential of NNMT as prognostic marker of gastric cancer.

Abstract
Schizophrenia is a severe psychiatric disease while its etiology and effective treatment are not completely clear. A rat model of schizophrenia was previously established by transfecting EGR3 gene into the hippocampus of rats. This study aimed to investigate the behavioral and cerebral alterations of the schizophrenic model rats and the risperidone effects. Twenty-six rats were divided into 3 groups: schizophrenia model group (E group), risperidone treatment group (T group), and healthy control group (H group). Morris water maze and open field test were used as behavioral tests, resting-state functional magnetic resonance imaging (fMRI) was performed after EGR3 gene transfection and risperidone therapy. Graph analyses were used for examining cerebral alterations of the rats. Behavioral tests demonstrated reduced spatial working memory and exploring unfamiliar space ability in schizophrenic model rats. Graph analyses revealed reduced regional architectures in the olfactory bulb, nucleus accumbens, and pineal gland in group E compared to group H (p < 0.05), while group T showed increased regional architecture in pineal gland compared to group E (p < 0.05). Besides, the regional architectures in the olfactory bulb, nucleus accumbens were lower in group T than group H, while the hippocampus showed increased regional architecture in group T compared to group H (p < 0.05). Schizophrenia induced several regional alterations in the cerebrum while risperidone can reverse part of these alterations. This study lends support for future research on the pathology of schizophrenia and provides new insights on the role of risperidone in schizophrenia.

Abstract
OBJECTIVE To explore the expression, function, and regulation mechanism of the long non-coding ribonucleic acid (lncRNA) tubulin alpha 4b (TUBA4B) in colorectal cancer (CRC) tissues and cells. PATIENTS AND METHODS Cancer and adjacent tissues were collected from 60 CRC patients. CRC cell lines SW480, SW620, HCT116, Caco-2, DLD-1 and HT29, and colonic epithelial cell line CCD841 were also enrolled. Then, the expression of TUBA4B in CRC tissues and cell lines was detected via quantitative Reverse Transcription-Polymerase Chain Reaction (qRT-PCR). In vitro assays [cell counting kit-8 (CCK-8) assay, clone formation assay, and flow cytometry] were performed to study the biological function of TUBA4B in CRC. Additionally, the downstream regulatory targets of TUBA4B were investigated through Western blotting analysis and qRT-PCR assay. RESULTS The results of qRT-PCR revealed that compared with adjacent tissues, the expression of TUBA4B was down-regulated in 47/60 CRC tissues (47/60, 78.3%). According to in vitro assays (CCK-8 assay, clone formation assay, and flow cytometry), over-expression of TUBA4B inhibited the proliferation and promoted the apoptosis of CRC cells. TUBA4B remarkably regulated mRNA and protein levels of p15 and p16. CONCLUSIONS LncRNA TUBA4B is down-regulated expression in CRC tissues and cells, which facilitates CRC cell proliferation and suppresses apoptosis by regulating the expressions of p15 and p16.

Abstract
OBJECTIVE To investigate the role and regulate the target of miRNA-411 on spinal cord injury. MATERIALS AND METHODS The microglia cultured in vitro was activated by lipopolysaccharide (LPS) to express the inflammatory phenotype. The inflammatory response through miRNA-411 transfection in microglia was measured to certain whether increased miRNA-411 suppressed interleukin-18 (IL-18) level to attenuate the inflammation amplification via downregulating JNK pathway. Furthermore, we established spinal cord injury (SCI) model in SD rats and further explored the glial inflammatory degree and neurological recovery following miRNA-411 treatment. Lastly, we estimated the hindlimbs function of SCI rats with miRNA-411 administration or not within four weeks at post-SCI. RESULTS In vitro, miRNA-411 inhibited IL-18 expression and downregulated JNK pathway, along with that inflammatory microglia were declined. In SCI rats, we detected the decreased amounts of inflammatory microglia and reduction of the inflammatory factors after miRNA-411 treatment. IL-18 and JNK pathway was also restrained resulted from increased miRNA-411. In addition, apoptosis degree in injury site reduced and survived axons were relatively multiple in the miRNA-411 group compared with the SCI group. The Basso-Beattie-Bresnahan (BBB) locomotor scores of miRNA-411 treated rats were superior to those in rats with no treatment. CONCLUSIONS MiRNA-411 increase ameliorates the inflammatory microglia-induced neurological lesion and promotes neural recovery by JNK pathway inhibition via negative targeting IL-18 in SCI.

Abstract
OBJECTIVES The burden of multimorbidity is increasing worldwide; however, little is known about trends in multimorbidity prevalence among Chinese older adults. We aimed to estimate the prevalence and trends of multimorbidity in community-dwelling older adults in Beijing. DESIGN Longitudinal. SETTING AND PARTICIPANTS Residents of Beijing aged ≥60 years. MEASUREMENTS Data were derived from the Beijing Longitudinal Study of Aging, using cluster, stratification, and random sampling. A total of 1842, 2914, and 1837 participants were included in the 2004, 2011, and 2017 sample, respectively. Multimorbidity was defined as the presence of two or more chronic conditions. Trends in multimorbidity were examined by age, sex, and geographical area. RESULTS The prevalence of multimorbidity was 32.5%, 52.9%, and 53.2% in 2004, 2011, and 2017, respectively, following an upward trend over time (P =0.003). A similar multimorbidity increase trend was present in age-, sex-, and region-stratified analysis for the 2004-2017 period (all P<0.05). The most common chronic diseases in 2004 were hypertension (34.3%), cataract (18.2%), coronary heart disease (CHD) (15.6%), stroke (14.3%), and chronic obstructive pulmonary disease (7.9%); in 2011, these were hypertension (49.6%), arthritis (30.9%), CHD (22.3%), stroke (21.9%), and diabetes (15.1%); in 2017, these were hypertension (54.4%), arthritis (26.3%), stroke (22.6%), cataract (20.5%), and CHD (20.1%). The proportion of older adults diagnosed with ≥3 chronic diseases significantly increased from 13.4% in 2004 to 73.1% in 2011 and 69.5% in 2017. CONCLUSIONS Multimorbidity is common and the overall and age-, sex-, and region-specific multimorbidity prevalence has been increasing over the past 13 years. Public health policies should account for the more complex care needs and growing costs associated with increasing prevalence of chronic disease and multimorbidity in Chinese older adults.

Abstract
Objective: To summarize the different teaching models and their effects in evidence-based medicine at home and abroad by qualitative method and systematic review. Methods: We searched the following databases (from inception to 13 May, 2019): PubMed, Embase, Proquest, Cochrane, Web of Science database and the Chinese databases (CNKI, Wanfang, SinoMed and VIP). To assess data strength and validity, risk of bias assessments were undertaken. Results: A total of 52 literatures were included in this study, including 21 Chinese-language literature and 31 English-language literature. PBL teaching model, mixed teaching model and workshop teaching model were the three teaching models with the largest number of studies in 20 teaching models. Conclusion: The evidence-based medicine teaching effect was closely related to the teaching models, so it is necessary to explore more suitable teaching models for the evidence-based medicine to improve the teaching effects.

Abstract
OBJECTIVE The aim of this study was to clarify the potential role of PCAT1 in the occurrence and development of ovarian cancer (OC). PATIENTS AND METHODS Expression levels of PCAT1 and NEK2 in OC tissues and cell lines were detected by quantitative Real-time polymerase chain reaction (qRT-PCR). Correlation between PCAT1 expression with tumor stage and prognosis of OC patients was analyzed. Knockdown or over-expression of PCAT1 and NEK2 were achieved by siRNA or lentivirus transfection, respectively. Subsequently, cell viability, apoptosis, cell cycle progression and migration were determined by cell counting kit-8 (CCK-8), flow cytometry and transwell assay, respectively. Furthermore, the protein levels of relative genes in Wnt pathway were detected by Western blot. RESULTS PCAT1 was highly expressed in OC tissues and cell lines, especially in tumor tissues with stage III-IV compared with stage I-II. The prognosis of OC patients with higher expression of PCAT1 was significantly worse than those with lower expression. In vitro experiments confirmed that PCAT1 knockdown obviously inhibited proliferative and migratory potentials, whereas induced apoptosis of OC cells. No significant changes were observed in cell cycle progression of OC cells after knockdown or overexpression of PCAT1. Meanwhile, overexpression of PCAT1 remarkably upregulated the expression level of NEK2, which was the target gene of PCAT1. Interestingly, NEK2 knockdown could obviously suppress cell migration. Furthermore, Western blot results elucidated that PCAT1 knockdown could inhibit the protein levels of relative genes in Wnt pathway in OC cells. CONCLUSIONS PCAT1 was highly expressed in OC tissues than adjacent normal tissues. PCAT1 overexpression significantly promoted proliferative and migratory potentials, whereas inhibited apoptosis of OC cells through upregulating NEK2 expression via Wnt pathway.

Abstract
Objective: To analyzes epidemiological characteristics of COVID-19 and provide evidence for adjustment for COVID-19 prevention and control strategies. Methods: The data of COVID-19 cases in Wuchang district reported as of 19 March, 2020 were obtained from National Notifiable Disease Report System of Chinese Disease Prevention and Control Information System. The software's of Excel 2010, SPSSS 22.0, Arc GIS10.2 and Joinpoint regression program 4.8.0.0 were used for statistical analysis. Results: A total of 7547 COVID-19 cases had been reported as of 19 March, 2020 in Wuchang district, including 5 448 confirmed cases (72.19%), 2009 clinical diagnosed cases (26.62%) and 90 asymptomatic cases case (1.19%). The age of the cases was (56.65±16.25) years and age ranged from 2 days to 105 years among confirmed cases, 2634 were males (48.35%) and 2814 were females (51.65%), 2 492 were retirees (45.74%). A total of 545 health workers were infected with SARS-CoV-2 (7.22% of all cases) including 365 confirmed cases and 5 cases have died. A total of 430 cases of death were reported with case fatality rate of 7.89% (430/5 448), case fatality rate of males (10.9%, 266/2 634) was higher than that of females (5.82%, 164/2 814). The first phase of epidemic peak was from January 24 to January 26, the second phase of epidemic peak was from February 1 to February 5 and there was no one of new confirmed case in one day for the first time on March 18. The first four Streets with the highest incidence rates of confirmed cases were Huanghelou Street (1 043.77/100 000), Ziyang Street (627.97/100 000), Yangyuan Street (503.67/100 000) and Shuiguohu Street (486.02/100 000). Compared with females, aged ≤50 years and mild cases of clinical classification respectively, males (RR=0.690, 95%CI: 0.322-1.478), aged >50 years (RR=11.745, 95%CI: 6.878-20.058), severe cases (RR=2.317, 95%CI: 1.789-3.000) and critical cases of clinical classification (RR=10.794, 95%CI: 7.997-14.569), and gender time-dependent covariate (RR=1.392, 95%CI: 1.053-1.840) were major influencing factors of prognosis of COVID-19 confirmed cases. Conclusions: The gender, ages and occupation of distribution were wide among COVID-19 cases in Wuchang district. Males, aged >50 years, severe cases and critical cases of clinical classification were influencing factors of prognosis of COVID-19 confirmed cases. The standardized management of discharged cases, asymptomatic infected cases and close contact persons were main measures to reduce incidence rates of COVID-19 cases.

Abstract
OBJECTIVE The aim of this study was to clarify the biological roles of microRNA-488 and transforming growth factor β1 (TGF-β1) pathway in the occurrence and progression of diabetic nephropathy (DN). MATERIALS AND METHODS Quantitative Real Time-Polymerase Chain Reaction (qRT-PCR) was used to detect the expressions of microRNA-488, fibrinogen factors coII, coIIV, and fibronectin (FN) in Human mesangial cells (HMCs) with high-glucose or low-glucose treatment. After transfection of microRNA-488 mimics or inhibitor, expression levels of coII, coIIV, and FN in HMCs were determined by qRT-PCR and Western blot. Their expressions in HMC cells treated with different doses of TGF-β1 at different time points were also detected. Finally, we evaluated the potential influence of microRNA-488 on TGF-β1-induced fibrosis of HMC cells by qRT-PCR. RESULTS Compared with low-glucose treatment, the expression of microRNA-488 markedly increased in HMCs treated with high-glucose, as well as coII, coIIV, and FN. Overexpression of microRNA-488 remarkably upregulated mRNA and protein levels of coII, coIIV, and FN, whereas microRNA-488 knockdown downregulated their levels. Expression levels of microRNA-488, coII, coIIV, and FN gradually upregulated with the increase of TGF-β1 dose and treatment duration. CONCLUSIONS MicroRNA-488 regulates the development of diabetic nephropathy-induced fibrosis by TGF-β1 pathway.
