Objective · To demonstrate the effect of TRIM59 on gliomagenesis and the molecular mechanism.Methods · TRIM59 protein expression in glioma specimens was analyzed by immunohistochemical staining,and in several glioma cell lines by Western blotting and quantative PCR.After TRIM59 was knocked down by shRNAs,cell proliferation,migration,colony formation,and orthotopic xenograft brain tumor development were detected.The signaling pathway of TRIM59 in gliomas was also explored by RNA-Seq and KEGG PATHWAY analyses.Results· The levels of TRIM59 protein expression in clinical glioma specimens were positively correlated with glioma malignancy.TRIM59 was highly expressed in LN229 and U87 glioma cells compared with normal human astrocytes.Knockdown of TRIM59 in these two cell lines with lentivirus-mediated shRNAs inhibited their proliferation,migration,and colony formation.Compared with the control xenograft models,knockdown of TRIM59 significantly inhibited glioma tumor growth.RNASeq and KEGG PATHWAY analyses identified that TRIM59 knockdown down-regulated 306 genes,among which PI3K/AKT signal pathway-related genes were the most.Moreover,TRIM59 knockdown suppressed AKT phosphorylation,whereas overexpression of a constitutively actived AKT (Myr-AKT)rescued TRIM59 knockdown-inhibited cell proliferation.Conclusion· TRIM59 is a new glioma oncogene,which may take effect through activating PI3K/AKT signaling pathway.

Objective To study the distribution characteristics of radon progeny at different air quality index (AQI) and evaluate health risks for the exposed population.Methods EQF3120 Monitor was used to monitor the concentration of radon and its daughters.The relevant air quality data was provided by the environmental monitoring station at Suzhou Industrial Park.SPSS 16.0 software was used for statistical description,principal component analysis and simple correlation analysis.Environmental radon exposure-caused effective dose to lung region was estimated by using the radon dose formulas.Results Radon progeny in fog haze weather in winter of Suzhou Industrial Park had relationships with NO2,SO2,O3,PM10 and PM2.5.The correlation coefficient of 214Bi were 0.741,0.681,-0.431,0.597 and 0.675.The correlation coefficient of radon progeny with PM2.5 was greater than that with PM10.When AQI ＞ 200,the effective dose to residents outdoor from radon and its short-lived progeny was 0.63 mSv/a.Conclusions Higher AQI results in higher concentration of attached radon progeny.There is little variation in concentration of unattached radon progeny.Fog and haze can increase exposure of the population to inhalated radon.

Objective:To investigate the status of glucolipid metabolism and insulin resistance in patients with first-episode non-medicated schizophrenia, and to explore their relationship with psychiatric symptoms and cognitive function.Methods:One hundred and seventeen patients with first-episode non-medicated schizophrenia admitted to Wenzhou Seventh People′s Hospital from January 2018 to August 2020 were included in case group, and 61 healthy subjects with physical examination during the same period were used as control group. The glucose metabolism, including serum fasting blood glucose (FBG), 2 h postprandial blood glucose (2 h PBG), fasting insulin (FINS), fasting C peptide; lipid metabolism, including triglyceride (TG), total cholesterol (TC), high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C); apolipoprotein A1 (Apo-A1) and homeostatic model assessment insulin resistance index (HOMA-IR) level were compared between 2 groups. The abnormal glucolipid metabolism and incidence rate of insulin resistance were counted in the two groups. According to the condition of abnormal glucolipid metabolism or insulin resistance in case group, the patients were divided into abnormal glucolipid metabolism group and non-abnormal group, and insulin resistance group and non-insulin resistance group. The psychiatric symptoms (positive and negative symptom scale, PANSS) and cognitive function (MATRICS consensus cognitive battery, MCCB) were compared between 2 groups. Pearson correlation analysis was used to explore the correlation between glucolipid metabolism and insulin resistance and psychiatric symptoms and cognitive function in case group.Results:The levels of glucolipid metabolism indexes of 2 h PBG, FINS, fasting C peptide, TG and HOMA-IR in case group were significantly higher than those in control group: (7.06 ± 1.88) mmol/L vs. (6.19 ± 1.53) mmol/L, (8.61 ± 2.46) mU/L vs. (6.25 ± 1.71) mU/L, (0.49 ± 0.16) nmol/L vs. (0.32 ± 0.09) nmol/L, (1.33 ± 0.47) mmol/L vs. (1.02 ± 0.24) mmol/L, 2.01 ± 0.71 vs. 1.51 ± 0.45 ( P<0.05); while the levels of HDL-C and Apo-A1 were significantly lower than those in control group: (1.19 ± 0.38) mmol/L vs. (1.57 ± 0.32) mmol/L, (1.21 ± 0.25) g/L vs. (1.43 ± 0.17) g/L ( P<0.05). The total incidence rate of abnormal glucolipid metabolism or insulin resistance in case group was significantly higher than that in control group: 62.39%(73/117) vs. 13.11%(8/61) ( P<0.05). The scores of dimensions of positive symptoms, negative symptoms and general psychopathology and total score of PANSS in combined group were significantly higher than those in non-abnormal group: (25.14 ± 5.09) scores vs. (22.95 ± 4.72) scores, (24.68 ± 5.25) scores vs. (22.05 ± 4.59) scores, (41.52 ± 5.85) scores vs. (38.12 ± 4.18) scores, (94.68 ± 11.64) scores vs. (85.43 ± 8.51) scores ( P<0.05).

The scores of continuous performance test-identical pairs (CPT-IP), working memory (WM), brief visuospatial memory test-revised (BVMT-R) and Mayer-Salovey-Caruso emotional intelligence test (MSCEIT) of MCCB scale in abnormal glucolipid metabolism group were significantly lower than those in non-abnormal group: (23.82 ± 5.21) scores vs. (27.15 ± 4.69) scores, (21.72 ± 5.95) scores vs. (25.35 ± 5.14) scores, (19.56 ± 5.28) scores vs. (22.34 ± 5.43) scores, (22.62 ± 5.13) scores vs. (26.47 ± 4.96) scores ( P<0.05), and the scores in insulin resistance group were significantly lower: (22.26 ± 4.84) scores vs. (25.42 ± 5.12) scores, (20.35 ± 4.87) scores vs. (23.46 ± 5.08) scores, (18.05 ± 4.27) scores vs. (20.98 ± 5.71) scores, (21.15 ± 4.67) scores vs. (24.48 ± 5.02) scores ( P<0.05). Pearson correlation analysis showed that 2 h PBG in case group was positively correlated with PANSS positive symptoms ( P<0.05), and was negatively correlated with CPT-IP and MSCEIT in MCCB scale ( P<0.05). FINS and HOMA-IR were positively correlated with positive symptoms, negative symptoms and PANSS total score ( P<0.05), and were negatively correlated with CPT-IP, WM, BVMT-R and MSCEIT ( P<0.05). HDL-C was negatively correlated with positive symptoms ( P<0.05), and was positively correlated with CPT-IP, WM and MSCEIT ( P<0.05). Apo-A1 was negatively correlated with positive symptoms and negative symptoms ( P<0.05), and was positively correlated with CPT-IP and WM ( P<0.05). Conclusions:Abnormal glucolipid metabolism and insulin resistance have a higher detection rate in first-episode non-medicated schizophrenia, and have a certain relationship with the psychiatric symptoms and cognitive impairment of patients.

Objective To investigate the value of kinetic features measured by computer-aided diagnosis (CAD)for breast MRI.Methods One hundred and sixty four lesions diagnosed pathologically by operation or biopsy comprised the analysis set.Automated lesion kinetic information from CADStream programs for breast MRI was identified.Three CAD variables were compared for benign and malignant lesions: initial phase peak enhancement (greatest percentage of signal intensity increase on first contrast enhanced sequence),delayed phase enhancement categorized by a single type of kinetics comprising the largest percentage of enhancement (washout,plateau,or persistent),and delayed phase enhancement categorized by single most suspicious type of kinetics (any washout ＞ any plateau ＞ any persistent).Morphological characteristics of breast lesions were described according to breast imaging and reporting data system (BI-RADS).Initial phase peak enhancement mean values between benign and malignant breast lesions were compared by using Wilcoxon rank-sum test,delayed phase enhancement categorized by a single type of kinetics comprising the largest percentage of enhancement or by single most suspicious type of kinetics between benign and malignant breast lesions were compared by using Chi-square test.Results There were 72 benign and 92 malignant breast lesions.A total of 123 (75.0％) mass lesions were identified,and the other 41 (25.0％) lesions showed no mass.Thirty lesions were BI-RADS-MRI 2,68 lesions were BI-RADS-MRI 3,43 lesions were BI-RADS-MRI 4,23 lesions were BI-RADS-MRI 5.Initial phase peak enhancement mean values of benign and malignant lesions were 237％ (69％ to 629％)and 336％ (86％ to 793％),respectively.There was no significant difference between benign and malignant lesions in initial peak enhancement mean value (Z =-1.626,P =0.104).Delayed phase enhancement categorized by single most suspicious type of kinetics (any washout ＞ any plateau ＞ any persistent) for benign and malignant lesions were 15,10,47 and 2,3,87 respectively.There was a significant difference between benign and malignant lesions (x2 =23.562,P =0.000).Initial peak enhancement value ＜ 100％ or ≥100％ were 5 and 67 for benign lesions,3 and 89 for malignant lesions,respectively.There was no significant difference between benign and malignant lesions at 100％ threshold (x2 =1.181,P =0.277).Delayed phase enhancement categorized by a single type of kinetics comprising the largest percentage of enhancement (washout,plateau,or persistent) for benign and malignant lesions were 48,6,18 and 47,15,30 respectively.There was no significant difference between benign and malignant lesions (x2 =4.496,P =0.106).Conclusions Of CAD kinetics analyzed,only delayed enhancement categorized by most suspicious type is helpful for the differentiation between benign and malignant lesions.However,there is significant overlap between initial peak enhancement at 100％ threshold or delayed kinetics categorized by largest percentage enhancement types of benign and malignant lesions,so lesion morphologic features should be considered.

Objective To explore the methods of labeling exogenous microglia with superparamagnetie iron oxide(SPIO)particles,and to monitor the labeled cells after transplantation into the normal rat and Alzheimer's disease(AD)model rat with MR scanning.Methods Microglia was labeled with SPIO particles by using transfection agent,hemagglutinating virus of Japan envelope(HVJ-E).Then the microglias which were labeled with SPIO were injected into the internal carotid artery of normal rat (n=5)and AD model rat(n=5).Three days after transplantation,follow-up serial T2*-weighted gradient-echo MR imaging was performed at 7.0T MRI system.MR images were correlated with histological findings.Results In the brain of normal rat,the labeled microglias were demonstrated as several dotty signalintensity decrease on T2*-weighted MR images.The dotty spots were sporadic around the brain.Histological analysis showed that most prussian blue staining-positive cells were well correlated with the area where a signal intensity decrease was observed in MRI.MR could detect the signal intensity change caused by a few labeled cells.In the brain of AD model rat,MR scan showed a well-defined hypointensity area in the region of Aβ42 iniection.Signal intensity decrease was not obvious in the region of saline injection.The number of iron-positive cells(454±47)/mm2 at sites of Aβ42 injection was much higher than that(83±13)/mm2 of saline injection(P＜0.05). Conclusion MR can be used as a non-invasive means of detecting transplanted labeled microglia in vivo,with the potential for future clinical application in cell therapy of AD.
