Objective To investigate the prevalence status and risk factors of mild cognitive impairment (MCI) in old people in pension facilities in Chongqing, China. Methods From October to November, 2015, the people above 60 years old in four pension facilities in Chongqing were cluster sampled. They were interviewed with Mini-Mental State Examination, Instrumental Activity of Daily Living Scale, self-made general situation questionnaire for the elderly and the Geriatric Depression Scale. Results There were 25 MCI patients identified in 84 old people selected, with the prevalence of 29.76%. MCI prevalence was different with the factors such as genders, educational levels, economical status, smoking, eating freshwater fish frequently, participating in outdoor activities frequently, playing Mahjong/chess/cards fre-quently, watching TV/listening to broadcast/reading newspaper frequently, participating in social activities frequently, having religious be-liefs, suffering high blood pressure (χ2>4.271, P<0.05). Based on multivariate Logistic regression analysis, male was the protective factor (OR=0.055, 95%CI:0.005~0.618), while high blood pressure was the risk factor (OR=8.281, 95%CI:1.278~53.646) to the MCI. Conclu-sion MCI is prevalent in old people in pension facilities in Chongqing, which needs intervention targeted to the risk foctors.

Objective:To investigate the epidemiological characteristics and prognostic affecting factors of non-small cell lung cancer (NSCLC) in Shanxi from 2015 to 2019.Methods:A total of 17 082 patients with NSCLC in Shanxi Provincial Cancer Hospital from January 2015 to December 2019 were selected as the research subjects. The medical records of all patients were retrieved, and the epidemiological characteristics of the patients' age, gender, occupation and smoking history were analyzed. All patients were given conventional treatment and followed up for 18 months. According to the follow-up results, they were divided into the death group (4 391 cases) and the survival group (12 691 cases). The single factor and multivariate logistic regression analysis was used to analyze the factors affecting the prognosis of patients.Results:Among 17 082 patients with NSCLC, there were 3 058 cases (17.91%) in 2015, 3 129 cases (18.32%) in 2016, 3 325 cases (19.46%) in 2017, 3 564 cases (20.86%) in 2018, and 4 006 cases (23.45%) in 2019, and the number of confirmed cases in different years showed an upward trend ( χ2 = 21.593, P < 0.05). The incidence rate of males was slightly higher than that of females [51.76% (8 841/17 082) vs. 48.24% (8 241/17 082)], 64.12% (10 953/17 082) occurred in the 61-80 years old population, and the occupational distribution was predominantly workers [34.08% (5 821/17 082)] and farmers [30.00% (5 124/17 082)]; there were 56.69% (9 683/17 082) patients with a history of smoking. Multivariate logistic regression analysis showed that lymph node metastasis, tumor staging Ⅲ-Ⅳ, sensitive mutations of epidermal growth factor receptor, and initial pleural effusion were independent factors influencing the poor prognosis of patients with NSCLC (all P < 0.05). Conclusions:The incidence of NSCLC in Shanxi from 2015 to 2019 is on the rise. The incidence of this disease is related to gender, age and occupation. There are many factors affecting the prognosis of patients, and targeted interventions can help improve the prognosis.

Objective:To investigate the regulatory effect of WNT1-inducible signaling pathway protein 2(WISP2)on macrophage polarization in palmitic acid(PA)and lipopolysaccharide(LPS)-induced inflammation.Methods:The macrophage cell line RAW264.7 was treated with different concentrations of WISP2 protein, and cell viability was determined by means of luminescence assay using Cell-Titer Glo to determine the concentration of WISP2.The cells were divided into control group, palmitic acid group, palmitic acid combined with different concentrations of WISP2 group(10 μg/L and 100 μg/L)and lipopolysaccharide group, lipopolysaccharide combined with different concentrations of WISP2 group(10 μg/L and 100 μg/L). mRNA expression of M1 and M2 macrophages phenotype of each group were detected by real-time quantitative polymerase chain reaction.The protein expression of important inflammatory factors, TNF-α and IL-6, were evaluated by ELISA.Results:Compared with the control group, both 10 μg/L and 100 μg/L WISP2 groups had no effect on the activity of RAW264.7 cells, but significantly up-regulated the expression of various inflammatory factors, including Tnfα(1.877±0.039, 2.202±0.034, F=309.7, P<0.001), Il6(1.418±0.056, 1.506±0.059, F=81.39, P<0.001), Mcp1(1.620±0.014, 1.982±0.125, F=71.45, P<0.001), Ccl3(1.892±0.118, 1.942±0.132, F=32.93, P<0.001), and iNos(1.691±0.201, 1.548±0.090, F=13.60, P<0.05). mRNA in macrophages, and significantly down-regulated the expression of anti-inflammatory factors, including Tgfβ(1.376±0.025, 2.152±0.107, F=1.846, P<0.05), CD206(2.123±0.031, 3.139±1.663, F=8.037, P<0.05), Il4(2.098±0.464, 2.494±0.141, F=48.68, P<0.01), and Il10(1.303±0.216, 1.574±0.274, F=5.774, P<0.05)mRNA, causing M1 type macrophage polarization.Compared with the control group, 100 μmol/L palmitic acid could mildly but significantly increase the expression of inflammatory factors such as TNF-α and IL-6 at the transcriptional and protein levels.Compared with palmitic acid stimulation alone, the combination of palmitic acid and WISP2 further promoted the protein expression of macrophage inflammatory factors TNF-α[(589.4±17.0)ng/L, (692.6±83.4)ng/L, F=56.38, P<0.05], IL-6[(15.13±1.14)ng/L, (13.33±1.22)ng/L, F=23.32, P<0.001]and the mRNA expression of chemokines Mcp1(160±9.796, 140±18.91, F=141.1, P<0.0001)and C cl3(17.76±1.92, 14.41±1.27, F=125.2, P<0.0001). Compared with the control group, 100 μg/L lipopolysaccharide strongly stimulated the expression of inflammatory factors such as TNF-α[(3444±423)ng/L, F=71.20, P<0.0001]and IL-6[(497.0±41.2)ng/L, F=63.50, P<0.0001]in macrophages at the protein level.Compared with lipopolysaccharide stimulation alone, the combination of lipopolysaccharide and WISP2 further significantly up-regulated the mRNA expression of chemokines Mcp1(106.8±8.7, 118.7±4.6, F=251.5, P<0.0001)and Ccl3(35.3±12.5, 116.4±4.5, F=160.1, P<0.0001). Conclusions:The adipokine WISP2 can promote M1 macrophage polarization in palmitic acid and lipopolysaccharide-induced inflammation, and it had distinct regulation in macrophage polarization under different inflammatory response conditions.

Objective:To investigate the effects of various concentrations of recombinant human WISP2 protein(WISP2)on lipid metabolism in HepG2 cells.Methods:HepG2 cells were treated with different concentrations(0, 0.4, 1 and 2 μg/L)of recombinant human WISP2 for 48 hours.Cell viability was detected by Cell-Titer, and enzymatic hydrolysis methods were used to measure intracellular triacylglycerol(TG)and total cholesterol(TC)levels.The mRNA expression was detected by quantitative real-time reverse transcription-PCR(RT-qPCR)and protein expression in HepG2 cells was detected by western blot.Results:Compared with the control group, the WISP2 groups treated with various concentration did not significantly reduce the viability of HepG2 cells.TG and TC in HepG2 cells were significantly increased by recombinant human WISP2 treatment(all P<0.05).The concentrations of TG in the 0.4, 1 and 2 μg/L recombinant human WISP2-treated groups were 1.254±0.039, 1.216±0.028 and 1.174±0.014)times the concentration in the untreated group, respectively( F=6.791, P=0.006).The concentration of TC in the untreated group was 1.264±0.057, 1.394±0.101 and 1.392±0.077), respectively, times the concentration in each of the treated groups( F=7.045, P=0.005).Further experiments found that the mRNA expression of sterol regulatory element binding protein 1(SREBP1), 3-hydroxy-3-methylglutaryl coenzyme A reductase(HMGCR), acetyl-CoA carboxylase(ACC), type 2 diacylglycerol acyltransferase(DGAT2)and the protein expression of SREBP1, ACC and fatty acid synthase(FAS)were significantly increased in the recombinant human WISP2-treated groups, compared with the control group(all P<0.05).However, the expression of lipid transporters such as the low-density lipoprotein receptor(LDLR), ApoB and ApoE and adipose triglyceride lipase(ATGL), a key lipolysis protein, was not significantly affected. Conclusions:Human recombinant WISP2 protein increases lipid levels in hepatocytes and the key underlying mechanisms may be through promoting lipid synthesis.
