Macroautophagy (referred to as autophagy hereafter) is a major intracellular lysosomal degradation pathway that is responsible for the degradation of misfolded/damaged proteins and organelles. Previous studies showed that autophagy protects against acetaminophen (APAP)-induced injury (AILI) via selective removal of damaged mitochondria and APAP protein adducts. The lysosome is a critical organelle sitting at the end stage of autophagy for autophagic degradation via fusion with autophagosomes. In the present study, we showed that transcription factor EB (TFEB), a master transcription factor for lysosomal biogenesis, was impaired by APAP resulting in decreased lysosomal biogenesis in mouse livers. Genetic loss-of and gain-of function of hepatic TFEB exacerbated or protected against AILI, respectively. Mechanistically, overexpression of TFEB increased clearance of APAP protein adducts and mitochondria biogenesis as well as SQSTM1/p62-dependent non-canonical nuclear factor erythroid 2-related factor 2 (NRF2) activation to protect against AILI. We also performed an unbiased cell-based imaging high-throughput chemical screening on TFEB and identified a group of TFEB agonists. Among these agonists, salinomycin, an anticoccidial and antibacterial agent, activated TFEB and protected against AILI in mice. In conclusion, genetic and pharmacological activating TFEB may be a promising approach for protecting against AILI.

Objective:To analyze the genetic etiology and prognosis in fetuses with increased nuchal translucency (NT) in order to assist in the clinical prenatal genetic counseling and diagnosis.Methods:This study retrospectively enrolled 1 658 cases of singleton pregnancy (<35 years old) receiving invasive prenatal diagnosis, including karyotype analysis and/or chromosome microarray analysis or copy number variation (CNV) sequencing, due to NT value ≥2.5 mm in the first trimester in Henan Provincial People's Hospital from August 2014 to December 2021. They were divided into different groups according to the thickness of NT (≥2.5-<3.0, ≥3.0-<3.5, ≥3.5-<4.5, ≥4.5-<5.5, ≥5.5-<6.5 and ≥6.5 mm groups) and abnormal ultrasound findings (isolated increased NT group, increased NT complicated by soft markers/non-severe structural abnormality group and increased NT complicated by severe structural abnormality group). The results of invasive prenatal diagnosis and pregnancy outcomes were compared between different groups using Chi-square test and trend Chi-square test. Results:The detection rates of numerical abnormalities of chromosomes were 15.8% (262/1 658) and 17.6% (252/1 431) when the NT thickness cut-off value were 2.5 mm or 3.0 mm, respectively. Overall, the detection rate of numerical abnormalities of chromosomes increased with thickness of NT ( χ2trend=180.75, P<0.001), ranging from 6.6% (44/671) in the NT≥2.5-<3.5 mm group to 45.6% (113/248) in the NT≥5.5 mm group. The incidence of pathogenic/likely pathogenic CNV(P/LP CNV) did not increased with NT thickness ( χ2trend=3.26, P=0.071), and the highest detection rate was observed in the NT≥4.5-<5.5 mm group (9.0%, 19/211). The detection rate of numerical abnormalities of chromosomes plus P/LP CNV in the isolated NT≥2.5-<3.0 mm group and NT≥3.0-<3.5 mm group were 5.3% (10/188) and 9.6% (36/375), respectively, however, the difference was not statistically significant ( χ2=3.06, P=0.080). The detection rates of numerical abnormalities of chromosomes plus P/LP CNV in the isolated NT≥3.5-<4.5 mm group and NT≥2.5-<3.0 mm complicated by soft markers/ non-severe structural abnormality group were 12.7% (52/410) and 24.1% (7/29), respectively, and the risk were 2.6 times (95% CI: 1.3-5.2) and 5.7 times (95% CI: 2.0-16.4) of the isolated NT≥2.5-<3.0 mm group, respectively. The pregnancy termination rate increased with the NT thickness ( χ2trend=304.42, P<0.001), ranging from 10.8% (23/212) in the NT≥2.5-<3.0 mm group to 90.7% (117/129) in the NT≥6.5 mm group. After exclusion of the pregnancies terminated due to numerical abnormalities of chromosomes and P/LP CNV, 87.6% (862/984) of the fetus with increased NT were born alive. Conclusions:The detection rate of numerical abnormalities of chromosomes increases with the thickness of NT. Invasive prenatal diagnosis is required for non-advance aged singleton pregnant women when fetuses present with isolated NT≥2.5 mm with or without soft markers/structural abnormalities.

Objective:To observe the morphological characteristics of urogenital hiatus in patients with gestational diabetes mellitus (GDM) after vaginal delivery.Methods:This study included 192 pregnant patients from Henan Provincial People′s Hospital who met the conditions between Jan.2020 and Aug.2021. All participants were screened for GDM by oral glucose tolerance test (OGTT) or fasting blood glucose at 24-28 weeks of pregnancy, and were divided into GDM group (34 cases) and non-GDM group (158 cases) based on the presence or absence of GDM. All participants underwent pelvic floor ultrasonography at the first trimester (6-8 gestational weeks), 3 days postpartum, 6 weeks postpartum, 6 months postpartum, and 1 year postpartum. Area of urogenital hiatus (AUH), transversal diameter of urogenital hiatus (TDUH) and anteroposterior diameter of urogenital hiatus (APDUH) were measured using Smart Pelvic. The Logistic regression model was used to calculate and match the propensity score between the GDM group and the non-GDM group.Results:In the non-GDM group, TDUH during rest maneuver at 6 weeks postpartum( P=0.319), the indicators during rest and contract maneuver at 6 months postpartum( P=0.586, 0.877, 0.164, 0.226, 0.465, 0.097), and TDUH during tension maneuver at 1 year postpartum( P=0.643) returned to the level of early pregnancy. In the GDM group, the indicators during rest maneuver and TDUH during contract maneuver at 6 months postpartum recovered to the level of early pregnancy ( P=0.647, 0.584, 0.376, 0.440), while APDUH and AUH during contract maneuver ( F=7.784, 9.785; P=0.005, <0.001) and the indicators during tension maneuver at 1 year postpartum( F=15.343, 11.974, 17.981; P<0.001) did not recover to the level of early pregnancy. After propensity score matching, APDUH and AUH during tension maneuver at 1 year postpartum in the GDM group were significantly greater than those in the non-GDM group( t=2.810, 2.926; P=0.006, 0.004). Conclusions:The pelvic floor muscles of GDM patients after vaginal delivery are more severely damaged, and the recovery speed is slower. Pelvic floor muscle exercise during pregnancy and enhanced postpartum follow-up are needed to prevent, diagnose and treat pelvic floor dysfunction early.

The tea beverages will be endowed with distinct aroma and taste, as well as various biologically active compounds including probiotic factors, when fermented with lactic acid bacteria (LAB). However, at present, few studies on the dynamics of flavors in tea soup at different fermentation stages were conducted. In this study, the composition of monosaccharides, aromatic components, free amino acids, and organic acids were measured, when the black tea beverages were fermented with Lactobacillus coryniformis FZU63 which was isolated from Chinese traditional kimchi. The results indicated that monosaccharides including glucose, fructose, mannose and xylose in black tea beverages are the main carbon sources for fermentation. In addition, the abundance of aromatic compounds in black tea soup are increased significantly at different fermentation stages, which endow the fermented black tea soup with fruit aroma on the basis of flowery and nutty aroma. Moreover, some bitter amino acids are reduced, whereas the content of sweet and tasty amino acids is elevated. Furthermore, the levels of lactic acid, malic acid, citric acid and other organic acids are accumulated during the fermentation. Additionally, sensory evaluation displays that black tea beverage is acquired with comprehensive high-quality after being fermented for 48 h. This study provides a theoretical basis to steer and control the flavor formation and quality of the fermented tea beverages during LAB fermentation.

The Zika virus (ZIKV) and dengue virus (DENV) flaviviruses exhibit similar replicative processes but have distinct clinical outcomes. A systematic understanding of virus–host protein–pro-tein interaction networks can reveal cellular pathways critical to viral replication and disease patho-genesis. Here we employed three independent systems biology approaches toward this goal. First, protein array analysis of direct interactions between individual ZIKV/DENV viral proteins and 20,240 human proteins revealed multiple conserved cellular pathways and protein complexes, including proteasome complexes. Second, an RNAi screen of 10,415 druggable genes identified the host proteins required for ZIKV infection and uncovered that proteasome proteins were crucial in this process. Third, high-throughput screening of 6016 bioactive compounds for ZIKV inhibition yielded 134 effective compounds, including six proteasome inhibitors that suppress both ZIKV and DENV replication. Integrative analyses of these orthogonal datasets pinpoint proteasomes as crit-ical host machinery for ZIKV/DENV replication. Our study provides multi-omics datasets for fur-ther studies of flavivirus–host interactions, disease pathogenesis, and new drug targets.

Objective:
To understand the serotypes, genotypes and transmission source of dengue viruses(DENV) isolated in Yunnan from 2013 to 2015.
Methods:
Viral RNA was extracted from serum samples of dengue fever(DF) cases at the acute stage in Yunnan, then the gene fragments of envelope protein(E) region were amplified by RT-PCR. The homology and phylogenetic analysis was made on the nucleotide and deduced amino acid sequences by bioinformatics softwares including Clustal X, DNAStar and MEGA5.
Results:
Viral nucleic acid detection and sequencing indicated that 40 E genes of DENV were obtained. The serotypes and genotypes of DENV were revealed by homology and phylogenetic analysis based on E genes of DENV. Fifteen virus strains belonged to DENV serotype 1(DENV-1), of these, 14(11 from Ruili, 1 from Lincang and 2 from Kunming) were genotype I(G-I), 1 from Kunming was G-V. Twenty-two virus strains belonged to DENV serotype 2(DENV-2), of these, 10 from Ruili were G-I and 12 from Xishuangbanna were G-IV. Two virus strains belonged to DENV serotype 3(DENV-3) and G-II. One virus strain belonged to DENV serotype 4(DENV-4) and G-I. All detected DENV genotypes were mainly predominant in Southeast Asia. All the 40 Yunnan DENV strains shared high homology with the DENV strains in Southeast Asia countries.
Conclusions
Four serotypes and multiple genotypes of DENV had been co-circulating in Yunnan from 2013 to 2015. The DENV transmitted from Southeast Asia countries was the main cause of DF in Yunnan. It is necessary to strengthen the surveillance and management on the imported cases of DF in Yunnan.

PurposeTo explore the value of ultrasound radio frequency technique in the quantitative evaluation of common carotid artery intima-media thickness (IMT) and elasticity change in patients with dyslipidemia, and to discuss the influence of high density lipoprotein cholesterol (HDL-C) upon carotid artery structure and elasticity function. Materials and Methods A hundred and fifty patients with abnormal serum lipid were selected as case group and further divided into three groups: group A--50 patients with hyperlipidemia and high HDL-C, group B--50 patients with hyperlipidemia and normal HDL-C, group C--50 patients with hyperlipidemia and low HDL-C. Meanwhile, 50 healthy people were enrolled in the study as control group (group D). The ultrasound radio frequency-data technique was employed to analyze the influence of hyperlipidemia and HDL-C upon IMT, CC,β, PWV and AIx.Results The IMT,β, PWV and AIx in group B were higher than those in group D, but group B had lower CC (the differences with statistic significance,t=5.141, 4.219, 4.898, 4.142 and-3.758,P<0.01). Compared with group A, group B had higher IMT,β, PWV and AIx and lower CC (the differences with statistic significance,t=3.425, 2.807, 2.913, 2.209 and-2.091,P<0.05 orP<0.01). Compared with group B, group C had higher IMT,β, PWV and AIx and lower CC (the differences with statistic significance,t=4.937, 2.195, 3.337, 2.067 and-3.049, P<0.05 orP<0.01). Group A had higher IMT and PWV than group D (the differences with statistic significance,t=2.236 and 2.407,P<0.05), but CC,β, and AIx showed no difference between group A and group D (t=-1.693, 1.845 and 1.967,P>0.05). In patients with hyperlipidemia, the increase of HDL-C led to the reduction of the common carotid artery IMT and wall stiffness and the increase of elasticity and vice versa.Conclusion The ultrasound radio frequency technique could measure the real-time common carotid artery IMT and elasticity automatically and accurately, thus provides reliable quantitative index for the evaluation of early artery structure and change of function in lipid lowering therapy.
