Macrophages are important immunocytes in human body , playing an important role in antigen and inflammation process.In recent years , it has shown that macrophage is a kind of cell mass with high plasticity , heterogeneity , diverse and variable immune functions .They can be polarized into different phenotypes in different microenvironments or stimulations , playing different roles in the process of inflammation .There are a variety of factors which can modulate macrophage polarization process , such as the de-velopment and progression of metabolic diseases .The polarization of adipose tissue macrophages and the factors in the regulation of macrophage polarization are summarized in this paper .

Patients with metastatic prostate cancer are typically managed with androgen deprivation therapy. Most patients initially respond to treatment, but many eventually develop castration-resistant prostate cancer. Neuroendocrine prostate cancer (NEPC) is a highly aggressive subtype of castration-resistant prostate cancer, which often results from neuroendocrine differentiation of prostate cancer cells. NEPC has a dismal outcome with an average survival of less than 1 year and exhibits less response to radiochemotherapy. At least 25%of patients with lethal castration-resistant prostate cancer are predicted to eventually develop this type of highly-aggres-sive NEPC. However, research on the molecular mechanism of NEPC is limited;thus, further studies are needed to explore the develop-ment and application of anticancer drugs for NEPC.

Objective To investigate the characteristics of cognitive impairment in patients with type 2 diabetes mellitus (T2DM),and to analyze the correlation of T2DM with its risk factors and serum insulin like growth factor-1 (IGF-1) levels Methods A total of 78 hospitalized patients with T2DM at our hospital from November 2011 to March 2012 were divided into the cognitive impairment group (n=39) and the non-cognitive impairment group (n=39) according to Montreal Cognitive Assessment (MoCA) scores,and general clinical data were collected.Levels of blood lipids,glycosylated hemoglobin (HbAlc),fasting blood glucose (FBG),fasting blood insulin (FBI) and other biochemical indicators were detected,insulin resistance index (HOMA-IR) scores were calculated,and serum IGF-1 levels were determined by the enzyme-linked immunosorbent assay (ELISA).Results The education levle was (8.94±4.13) years for the cognitive impairment group and (12.65[2.50) years for the non-cognitive impairment group,and there was a statistically significant difference between the two groups (P=0.004).HbAlc levels were (9.69 ± 1.25) and (7.96 ± 1.31) for the cognitive impairment group and the non-cognitive impairment group,respectively,and were statistically difference between the two groups (P =0.001).Serum IGF-1 levels were (122.60±11.56) mmol/L and (139.32±9.57) mmol/L in the cognitive impairment group and the non-cognitive impairment group,respectively,and had a statistically significant difference between the two groups (P =0.037).Additionally,compared with the non-cognitive impairment group,scores on visuospatial ability,naming,language,abstraction,delayed recall and orientation were lower in the cognitive impairment group (P＜[0.05 or 0.01).Moreover,MoCA scores were negatively correlated with TC,LDL-C,TG,HbAlc,FBI levels and HOMA IR (r=0.498,-0.411,0.414,-0.452,-0.449,-0.539,respectively,P＜0.05 for all),and positively correlated with education lcvcl and IGF 1 level (r=0.579 and 0.491,respectively,P＜0.05 for both) Conclusions Cognitive impairment caused by T2DM is prominent in visuospatial ability,language,memory and executive functions,and is closely related to poor education,poor glycemic control,dyslipidemia and insulin resistance.Furthermore,decreased serum IGF-1 levels might be a risk factor for diabetic cognitive impairment.

Objective Urinary protein is closely related to the development and progression of major vascular lesionsin diabetic patients.This study was to investigate the correlation between brachial-ankle pulse wave velocity(baPWV) and urinary protein in patients with type 2 diabetes mellitus ( T2DM) . Methods According to the level of 24-hour urinary albumin ( UAL) , 142 T2DM patients were divided into three groups:control (UA<30 mg, n=84), microalbuminuria(UAL<300 mg, n=26), and clinical albuminuria group ( UAL≥300 mg, n=33) .All the patients underwent examination offasting blood glucose, blood lipid, renal function, HbA1c, islet func-tion, C-reactive protein, blood pressure, and BMI.Their baPWV was determined with an Omron atherosclerosis detector and the correla-tion of baPWV with other factors evaluated by Pearson analysis and multivariate linear regression analysis. Results The baPWVwas significantly higher in themicroalbuminuria([1649.19±229.36]cm/s) and clinical albuminuria ([1759.21±291.05]cm/s) than in the control group ([1522.33±248.37]cm/s) (P<0.05).Pearson analysis showed a positive correlation between 24-hour UAL and baPWV ( r=0.347, P<0.01) and multivariate linear regression analysis manifested the same correlation ( P<0.05) . Conclusion The level of urinary protein is closely correlated with baPWV in T2DM patients.

Objective To compare the detection rate of esophageal and cardiac mucosal lesions be?tween screening endoscopy and conventional routine endoscopy. Methods Using iodine staining,a total of 8 918 patients aged 40?69 were screened for esophageal and cardiac early cancer in Xianju and Tiantai county of Zhejiang Province from January 2010 to July 2013.Matched with age, data of 43 834(the conven?tional group) patients who underwent routine endoscopy during the same time period were also retrieved. The detection rates of esophageal and cardia mucosa lesions in both groups were compared and analyzed. Results The detection rate of esophageal mucosal lesions in screening group was significantly higher than that in the conventional group[7?? 48%(667/ 8 918)VS 2?? 17%(953/ 43 834),P<0?? 001].The total detection rate was the lowest in 2010 among 4 years, while that in 2011?2013 were higher and similiar. The detection rate of cardiac mucosal lesions in screening group was higher than that in the conventional group [ 0?? 78%(70/ 8 918)VS 0?? 70%(309/ 43 834)] without significant difference(P>0?? 05). The detection rates of low grade intraepithelial neoplasia, high grade intraepithelial neoplasia and mucosa cancer and total detection rates between 2 groups were similar(P>0?? 05). Conclusion Through training, endoscopists can grasp the skills of finding esophageal mucosal lesions. Iodine staining should be used as addition to conventional endos?copy in areas with high incidence of esophageal cancer. Conventional white light endoscopy plays a limited role in detection of cardia mucosal lesion, depending on joint inspection of other related methods.

IFIT family genes are a kind of interferon stimulated genes (ISGs), and play important roles in antiviral sector and immunity regulation. To study the regulatory effect of IFIT family genes during influenza A virus (IAV) infection, we used RNA-sequencing analysis (RNA-Seq) technique and found that when 293T cells were infected by A/WSN/33 (WSN), the concentration of IFIT family genes were increased. Further study reveals that overexpression of IFIT2 or IFIT3 could inhibit IAV replication and transcription, and cause the dose-dependent inhibition of polymerase activity of vRNP. In addition, IFIT2 and IFIT3 encoding protein could colocalize with NS1 in 293T cells infected by WSN, indicating that they might interact with each other. The results suggest that IFIT family genes can inhibit the replication and transcription of IAV, which contributes to our understanding of the regulatory effect of host factors during influenza virus infection.

Objective To evaluate the effectiveness of bioelectrical impedance analysis(BIA) interventions on volume status in hemodialysis patient. Methods Searched The Cochrane Library, PubMed, EMbase, EBsco, Wanfang Data, China Biology Medicine, China National Knowledge Infrastructure to collect clinical trials. The retrieval time was from database to July 15, 2016. The studies were selected according to the inclusion and exclusion criteria and were critically appraised by two reviewers. Then the data of included studies were extracted. Meta-analysis was conducted by using RevMan 5.3 software and descriptive analysis. Results Ten clinical trials were included six random control trial, one controlled clinical trail, three longitudinal study, involving 2009 patients. The results of Meta-analysis showed that the effectiveness of BIA interventions on volume management could improve blood pressure (P=0.001), protect the heart function(left ventricular mass index,P=0.002), compared with the clinical evaluation method, the BIA assessment of dry weight of hemodialysis patients could reduce hospitalization rate 14%. Descriptive analysis showed that BIA intervention volume management had certain advantages for the survival benefit of patients, but the current research was still few, had not yet come to a certain conclusion. Conclusions BIA can improve the management of the volume status and dry weight of hemodialysis patients, so as to it can improve the clinical benefit and survival benefit of patients.Better methods and guidelines for assessing DW and using BIA need to be developed.We propose that experienced HD nursing staff be trained in the use of the BIA to help monitor patient over hydration and approximate dry weight in consultation with the nephrologists responsible for the care of these patients so as to obviate excessive residual over hydration between nephrology reviews.

Ovarian cancer is a heterogeneous malignant tumor,one of the most common causes of cancer death in women worldwide,and there is currently no effective treatment available for its treatment,which seriously affects women's life and health.In order to deeply explore the pathogenesis of ovarian cancer and study the specific therapeutic drugs and methods,this paper summarizes,summarizes,assigns and evaluates the clinical characteristics of traditional Chinese and Western medicine for ovarian cancer,and screens out a more complete animal model.Through CNKI,Wanfang,Pubmed and other databases,the relevant content of ovarian cancer animal models was collected and sorted,and the model diagnostic indicators were assigned and the consistency was evaluated.In the evaluation of the model,it is found that the animal model of spontaneous ovarian cancer can simulate the pathogenesis process of human natural ovarian cancer,and the model has high modulus rate,high similarity,and high consistency with the clinical characteristics of traditional Chinese and Western medicine.The subcutaneous tumor graft type model and the blood stasis type model were in good clinical agreement with traditional Chinese medicine,a high degree of similarity,and a longer survival time.At present,animal models of ovarian cancer are mainly based on Western medicine models,and research on animal models consistent with traditional Chinese medicine syndromes is rare.Therefore,the improvement direction of ovarian cancer animal models and the necessity of improving the evaluation system are proposed,so as to make the animal models of ovarian cancer more clinical,and provide a theoretical basis for the determination of the efficacy of traditional Chinese medicine and the discussion of pharmacological effects of ovarian cancer,and provide a theoretical basis for the subsequent research on the pathogenesis and treatment measures of ovarian cancer,in order to improve the model of combining ovarian cancer symptoms in line with the clinical characteristics of traditional Chinese medicine and Western medicine.

Objective:To assess the relationship between serum total bilirubin and fundus arteriosclerosis in different genders.Methods:The physical examination data of Huadong Sanatorium in 2018 were analyzed, and a total of 26 275 people were included in this retrospective cross-sectional study. The age of this study was 18-86 (47.7±11.1) years old. Among them, there were 15 244 males (58.02%) and 11 031 females (41.98%). Participants were divided into 4 groups according to total bilirubin quartile values: Q1<11.50 μmol/L, Q2∶11.50-13.93 μmol/L, Q3∶13.94-17.14 μmol/L and Q4>17.14 μmol/L. The relationship between total serum bilirubin and fundus arteriosclerosis is determined using univariate and multivariate logistic regression analysis methods. The restricted cubic spline method was used to detect the dose-response relationship between total bilirubin and fundus arteriosclerosis. Results:In males, univariate analysis showed that high level of total bilirubin was a protective factor for fundus arteriosclerosis ( OR=0.87, 95% CI 0.78-0.97, P=0.012). After adjusting for other confounding factors, multivariate analysis showed that high level of total bilirubin remained as an independent protective factor for fundus arteriosclerosis ( OR=0.86, 95% CI 0.74-0.99, P=0.047). There was a linear dose-response relationship between total bilirubin level and fundus arteriosclerosis ( P=0.012). In females, univariate analysis showed that there were no statistically significant association between high level of total bilirubin and fundus arteriosclerosis ( OR=0.96, 95% CI 0.80-1.17, P=0.709). After adjusting for other confounding factors, multivariate analysis showed no statistically significant association between high level of total bilirubin and fundus arteriosclerosis ( OR=0.98, 95% CI 0.76-1.27, P=0.888). No linear dose-response relationship between total bilirubin level and fundus arteriosclerosis was found in females ( P=0.253). Conclusion:There are gender differences in the relationship between total bilirubin and fundus arteriosclerosis in this cohort. Elevated levels of total bilirubin are associated with fundus arteriosclerosis in males but not in females.

With the accelerating process of aging, the burden of elderly care in China is increasing dramatically. However, the current care models were difficult to meet the multi-level and diversified needs of the elderly. Time banking mutual care model is proposed as an important auxiliary model. Since the elderly in urban communities are the major participants of time banking mutual care model, understanding their willingness to participate is very important for the effective implementation and sustainable development of time banking mutual care model. This paper summarizes the research progress and the major influencing factors of the willingness of the elderly to participate in time banking mutual care model, in order to provide theoretical support for alleviating the increasingly severe burden of elderly care in China and realizing active aging.
