Sesquiterpenes and polyphenols with glucose-uptake stimulatory and antioxidant activities from the medicinal mushroom Sanghuangporus sanghuang / 中国天然药物

A chemical investigation on the fermentation products of Sanghuangporus sanghuang led to the isolation and identification of fourteen secondary metabolites (1-14) including eight sesquiterpenoids (1-8) and six polyphenols (9-14). Compounds 1-3 were sesquiterpenes with new structures which were elucidated based on NMR spectroscopy, high resolution mass spectrometry (HRMS) and electronic circular dichroism (ECD) data. All the isolates were tested for their stimulation effects on glucose uptake in insulin-resistant HepG2 cells, and cellular antioxidant activity. Compounds 9-12 were subjected to molecular docking experiment to primarily evaluate their anti-coronavirus (SARS-CoV-2) activity. As a result, compounds 9-12 were found to increase the glucose uptake of insulin-resistant HepG2 cells by 18.1%, 62.7%, 33.7% and 21.4% at the dose of 50 μmol·L

Role of histone acetylation in the pathogenesis of IgA nephropathy / 上海交通大学学报（医学版）

Objective: To study the role of abnormal histone acetylation modification in the pathogenesis of IgA nephropathy (IgAN), and explore the pathogenesis of IgAN from the perspective of epigenetics. Methods: 30 patients with primary IgAN and 19 healthy controls were included. Of the 19 controls, 16 cases were used to collect blood samples and 3 cases were used to collect normal renal tissues. Peripheral venous blood was collected to extract mononuclear cells (PBMC) for detection. The levels of histone H3 and H4 acetylation in PBMC of IgAN group and healthy control group were detected by ELISA. Real-time PCR was used to detect the mRNA expressions of P300, CREBBP, HDAC1-3, HDAC7, HDAC8, C1GALT1 and ST6GALNAC2. The acetylation levels of histone H3 and H4 in promoter regions of C1GALT1 and ST6GALNAC2 were detected by chromatin immuneprecipitation (CHIP). The protein expression of HDAC1 and H3Ac was detected by immunofluorescence. T-test was used for statistical analysis. Results: Compared with the healthy control group, the acetylation levels of H3 and H4 in IgAN group were significantly higher than those in healthy control group (P=0.035, P=0.012);the mRNA expressions of P300, CREBBP, HDAC1, HDAC8 and ST6GALNAC2 were significantly increased in IgAN group (P=0.002, P=0.001, P=0.001, P=0.045 P=0.012); the mRNA expressions of HDAC2 and C1GALT1 were decreased significantly (P=0.035, P=0.008); the acetylation degree of H3 and H4 in C1GALT1 promoter region was significantly decreased (P=0.043, P=0.005), the degree of H3 and H4 acetylation in the promoter region of ST6GALNAC2 gene was increased significantly in IgAN group (P=0.038, P=0.021);immune fluorescent results of renal tissue indicated that the HDAC1 protein expression was increased obviously, and H3Ac protein expression was significantly reduced in the renal tissue of IgAN patiegts. Conclusion: Abnormal acetylation modification exists in IgAN patients. Histone acetylation modification may participate in the pathogenesis of IgAN by regulating the expression of glycosylase gene.

Role of LncRNAs in cell senescence and therapeutic targets / 中国药理学通报

Long non-coding RNAs (LncRNAs) are non-coding RNAs with a length of more than 200 bp. Cellular senescence is a stable proliferative stagnation state, which is irreversible and may be caused by a variety of factors, such as telomere shortening, oncogene induction or oxidative stress. Multiple factors are involved in cellular senescence, in which p53/p21 and pl6/Rb are major regulators of cellular senescence in different cell types. Cellular aging has been extensively studied as a powerful tumor suppressor mechanism to counter the emergence of oncogenes. In this review, the mechanism of action and therapeutic targets of LncRNAs in senescent cells are explored in depth.

Validity and reliability of the Chinese Attention to Positive and Negative Inventory in college students / 中国心理卫生杂志

Objective:To translate the Attention to Positive and Negative Inventory(APNI)and analyze the validity and reliability in Chinese undergraduates sample,to offer a convenient and reliable tool of measuring the cognitive bias for national researchers. Methods:The English-version APNI went through translation into Chinese, retroversion into English,translation into Chinese again,and revision several stages. Two parts of samples (1450 Chinese college students)were surveyed. Sample one (n=1000)was used for item analysis,exploratory factor a-nalysis (EFA),concurrent validity and reliability analysis,while sample 2 (n=450)was used for confirmatory fac-tor analysis (CFA). Totally 68 subjects of sample 1 were randomly chosen and resurveyed with an interval of one week. Beck depression inventory (BDI-II)and patient health questionnaire (PHQ-9)was used for concurrent validi-ty. Results:Item analysis indicated that the 22 items of Chinese APNI had good discriminability. EFA focused onattention to positive information(API)and attention to negative information(ANI)two factors. CFA showed good model fit (χ2 =1376,RMESA=0. 09,CFI=0. 94). Concurrent validity result showed that the total scores of BDI-II and PHQ-9 was negatively correlated with total scores of API (r=-0. 24,-0. 29,Ps<0. 01 ),and posi-tively correlated with total scores of ANI (r=0. 36,0. 31,Ps<0. 01). The Cronbach'αcoefficients of API and ANI sub-scale were 0. 86 and 0. 82,while the retest reliability coefficients were 0. 79 and 0. 62. Conclusion:It suggests that the Chinese APNI has good validity and reliability in a sample of college students,which could be used to eval-uate the cognitive bias of Chinese college students.

The discordant results in serum through reverse syphilis screening algorithm / 中华流行病学杂志

Objective The emerging reverse sequence on syphilis screening program generates special discordant results,characterized with the appearance of both positive treponemal test and negative nontreponemal test at the same time.The aim of this study was to analyze the characteristics of the discordant results among low syphilis prevalence population in China,to provide evidence for improving the process of reverse sequence syphilis screening program.Methods Laboratory data was retrospectively analyzed,under reverse sequence screening algorithm selecting ELISA as the initial screening test for syphilis.All the screening reactive samples were tested by TPPA for confirmation and by quantitative TRUST for the reactivity of syphilis.Results 666 out of a total of 21 049 serum samples were reactive under the screening program.Among the 666 reactive samples,169 were reactive to TRUST.One in the 169 samples was confirmed negative on TPPA,and the faulse positive rate on ELISA was 0.6％ (1/169).In those 666 reactive samples,497 were nonreactive to TRUST.74 in the 497 samples were confirmed negative to TPPA,with faulse positive rate of ELISA as 14.9％ (74/497).In the group of 591 TPPA confirmed positive samples,the TRUST negative rate was found 71.6％ (423/591),significantly higher than the TRUST positive rate (chi-square test,x2=110.025,P=0.000).Conclusion Among the results fiom reverse sequence syphilis screening program,majority of the samples which showed positive treponemal antibody,would have negative nontreponemal antibody.We therefore recommended a more reasonable reverse sequence syphilis algorithm to be used.Faulse positivity could be eliminated if TPPA was performed on all screening reactive samples by ELISA a first and then followed by quantitative TRUST on samples that were TPPA confirmed as positive.
