    Xie Z, Yan Y, Peng K
    Front Psychiatry, 2023;14:1237005.
    PMID: 37575587 DOI: 10.3389/fpsyt.2023.1237005
    Winnicott is an outstanding representative of the School of Object Relations, and his unique psychoanalytic treatment views have been greatly influential to the psychoanalytical community. Winnicott emphasizes the impact of facilitating environment and the key role of the maternal-child relationship in the early psychological growth of individuals. He puts forward the ideas of the development mechanism of the true self and the false self, which builds a bridge between the characteristics of adult psychopathology and the characteristics of early maternal-child relationships, providing a new perspective for research on individual self-development and psychoanalysis. Winnicott creatively introduces the concepts of the transitional object and the transitional phenomena into the theories of Object Relations. He relates the transitional experience to the field of mental health, and extends it from the relationship between the mother and the child to adult life, which not only has had a revolutionary impact on modern psychoanalysis but also literature, aesthetics, and other fields. Winnicott highlights the importance of the patient's emotional development in the treatment. He advocates holding the patients' sentiments and meeting their emotional needs. He also approves of the emotional reparenting of the patients, to make them gain the ability to establish a relationship with the real world. His treatment views formed through a large number of clinical practices are very practical and full of humanistic care. This review summarizes Winnicott's psychoanalytical treatment views as well as his marvelous original concepts, and analyzes the hot topics of academic research on his theories based on a visualization analysis by using the software CiteSpace, which includes data in the Web of Science Core Collection published from 1978 to 2023 with 365 papers involved. The study provides a macroscopic and panoramic review of Winnicott's theories, and it clearly shows Winnicott's significant influence on the field of psychoanalysis and related fields.
  2. Fulltext When and why are employees willing to engage in voice behavior: a power cognition perspective

    Previous studies have found that sense of power is an important predictor of employee voice; however, the mechanism underlying the relationship between these factors remains unclear. To explore this mechanism, 642 valid questionnaires from 45 enterprises were used to conduct an empirical test based on the approach-inhibition theory of power. The results showed that sense of power can affect error risk taking positively, error risk taking mediates the relationship between sense of power and employee voice; and power congruence moderates both the direct relationship between sense of power and employee voice and their indirect relationship via error risk taking. This study thus provides a useful reference for improving employees' enthusiasm for voice behavior and can help enhance the competitiveness of enterprises.

    Guan M, Tan H, Fazhan H, Xie Z, Shi X, Zhang Y, et al.
    Mitochondrial DNA B Resour, 2018 Oct 26;3(2):1244-1245.
    PMID: 33474478 DOI: 10.1080/23802359.2018.1532345
    The mitochondrial genome plays an important role in studies on phylogeography and population genetic diversity. Here we report the complete mitochondrial genome of Lupocycloporus gracilimanus (Stimpson, 1858) which is the first mitochondrial genome reported in genus Lupocycloporus by now. The mitogenome is 15,990 bp in length, consisting of 13 protein-coding genes, 22 transfer RNA genes, two ribosomal RNA genes and a putative control region. The phylogenetic analysis showed that L. gracilimanus was closest to genus Scylla. The present research should provide valuable information for phylogenetic analysis and classification of Portunidae.
  4. Fulltext Characterization of the complete mitochondrial genome of Xanthid crab, Atergatis integerrimus from China (Decapoda: Brachyura) and its phylogenetic analysis
    Xie Z, Tan H, Lin F, Guan M, Waiho K, Fang S, et al.
    Mitochondrial DNA B Resour, 2018 Mar 27;3(1):397-398.
    PMID: 33474181 DOI: 10.1080/23802359.2018.1456374
    The complete mitochondrial genome sequence of Atergatis integerrimus from China has been amplified and sequenced in this study. The mitogenome assembly was found to be 15,924 bp in length with base composition of A (32.88%), G (10.58%), C (20.87%), T (35.66%), A + T (68.54%), and G + C (31.46%). It contained 13 protein-coding genes, 22 transfer RNA genes, two ribosomal RNA genes and a control region. The phylogenetic position was constructed and the A. integerrimus was closely clustered with Pseudocarcinus gigas and Leptodius sanguineus. The complete mitochondrial genome sequence would be useful for further understanding the evolution of A. integerrimus.
  5. Fulltext The whole mitochondrial genome of the mangrove crab, Metopograpsus frontalis (Miers, 1880) (Decapoda, Grapsidae) and its phylogenetic relationship
    Guan M, Liu X, Lin F, Xie Z, Fazhan H, Ikhwanuddin M, et al.
    Mitochondrial DNA B Resour, 2018 Mar 14;3(1):368-369.
    PMID: 33490509 DOI: 10.1080/23802359.2018.1450685
    In this study, we sequenced and analyzed the whole mitochondrial genome of Metopograpsus frontalis Miers, 1880 (Decapoda, Grapsidae). The circular genome is 15,587 bp in length, consisting of 13 protein-coding genes, 22 transfer RNA genes, 2 ribosomal RNA genes, as well as a control region. Both atp8/atp6 and nad4L/nad4 share 7 nucleotides in their adjacent overlapping region, which is identical to those observed in other Grapsidae crabs. The genome composition and gene order follow a classic crab-type arrangement regulation. The phylogenetic analysis suggested that Grapsidae crabs formed a solid monophyletic group. The newly described mitochondrial genome may provide genetic marker for studies on phylogeny of the grapsid crabs.
  6. Clone, expression and plasminogen binding property of three fructose-1,6-bisphosphate aldolases from Clonorchis sinensis
    Li S, Lu BP, Feng J, Zhou JJ, Xie ZZ, Liang C, et al.
    Trop Biomed, 2020 Dec 01;37(4):852-863.
    PMID: 33612738 DOI: 10.47665/tb.37.4.852
    Fructose-1,6-bisphosphate aldolase (FbA), a well characterized glycometabolism enzyme, has been found to participate in other important processes besides the classic catalysis. To understand the important functions of three fructose-1,6-bisphosphate aldolases from Clonorchis sinensis (CsFbAs, CsFbA-1/2/3) in host-parasite interplay, the open reading frames of CsFbAs were cloned into pET30a (+) vector and the resulting recombinant plasmids were transformed into Escherichia coli BL21 (DE3) for expression of the proteins. Purified recombinant CsFbAs proteins (rCsFbAs) were approximately 45.0 kDa on 12% SDS-PAGE and could be probed with each rat anti-rCsFbAs sera by western blotting analysis. ELISA and ligand blot overlay indicated that rCsFbAs of 45.0 kDa as well as native CsFbAs of 39.5 kDa from total worm extracts and excretory-secretory products of Clonorchis sinensis (CsESPs) could bind to human plasminogen, and the binding could be efficiently inhibited by lysine analog ε-aminocaproic acid. Our results suggested that as both the components of CsESPs and the plasminogen binding proteins, three CsFbAs might be involved in preventing the formation of the blood clot so that Clonorchis sinensis could acquire enough nutrients from host tissue for their successful survival and colonization in the host. Our work will provide us with new information about the biological function of three CsFbAs and their roles in hostparasite interplay.
  7. Fulltext Remodeling of the gut microbiome during Ramadan-associated intermittent fasting
    Su J, Wang Y, Zhang X, Ma M, Xie Z, Pan Q, et al.
    Am J Clin Nutr, 2021 May 08;113(5):1332-1342.
    PMID: 33842951 DOI: 10.1093/ajcn/nqaa388
    BACKGROUND: Intermittent fasting is a popular dietary intervention with perceived relatively easy compliance and is linked to various health benefits, including weight loss and improvement in blood glucose concentrations. The mechanistic explanations underlying the beneficial effects of intermittent fasting remain largely obscure but may involve alterations in the gut microbiota.

    OBJECTIVES: We sought to establish the effects of 1 mo of intermittent fasting on the gut microbiome.

    METHODS: We took advantage of intermittent fasting being voluntarily observed during the Islamic faith-associated Ramadan and sampled feces and blood, as well as collected longitudinal physiologic data in 2 cohorts, sampled in 2 different years. The fecal microbiome was determined by 16S sequencing. Results were contrasted to age- and body weight-matched controls and correlated to physiologic parameters (e.g., body mass and calorie intake).

    RESULTS: We observed that Ramadan-associated intermittent fasting increased microbiome diversity and was specifically associated with upregulation of the Clostridiales order-derived Lachnospiraceae [no fasting 24.6 ± 13.67 compared with fasting 39.7 ± 15.9 in relative abundance (%); linear discriminant analysis = 4.9, P 

  8. Fulltext The complete mitochondrial genome of Varuna yui (Decapoda: Brachyura: Varunidae) and its phylogeny
    Lin F, Xie Z, Fazhan H, Baylon JC, Yang X, Tan H, et al.
    Mitochondrial DNA B Resour, 2018 Feb 23;3(1):263-264.
    PMID: 33474136 DOI: 10.1080/23802359.2018.1443043
    The complete mitochondrial genome plays an important role in the research on phylogenetic relationship. Here, we reported the first complete mitochondrial genome sequence of Varuna yui Hwang & Takeda, 1986 (Varunidae). The complete mtDNA (15,915 bp in length) consisted of 13 protein-coding genes, 22 tRNAs, two rRNA genes, and a control region. The gene arrangement was identical to those observed in the Varunidae species. The phylogenetic analysis suggested that V. yui had close relationship with other Varunidae species (Helicetient sinensis, Eriocher sinesis, etc.). The newly described genome may facilitate further comparative mitogenomic analysis within Varunidae species.
  9. Fulltext Rehabilitation care of patients with neurogenic bladder after spinal cord injury: A literature review
    Xiang L, Li H, Xie QQ, Siau CS, Xie Z, Zhu MT, et al.
    World J Clin Cases, 2023 Jan 06;11(1):57-64.
    PMID: 36687186 DOI: 10.12998/wjcc.v11.i1.57
    This article reviews the research progress of rehabilitation treatment and nursing care of patients with neurogenic bladder after spinal cord injury, in order to provide reference for the rehabilitation treatment and nursing care of patients. We reviewed recent medical literature on patients with neurogenic bladder, focusing on neurogenic bladder caused by spinal cord injury. We analyzed 30 recent of publications in patients with neurogenic bladder after spinal cord injury, in addition to reviewing and evaluating the commonly used rehabilitation nursing methods for neurogenic bladder. Psychological counseling is a vital aspect which cannot be neglected in the process of neurogenic bladder rehabilitation. Hitherto, the commonly used drug and surgical treatments may have negatively impacted the mental health of patients in varying degrees. However, in clinical practice, applying intermittent catheterization in patients who have neurogenic bladder with spinal cord injury may help improve patients' life quality, mitigate psychological burden, and reduce negative emotions.

    ETHNOPHARMACOLOGICAL RELEVANCE: Yishen Tongluo formula (YSTLF) is formulated based on traditional Chinese medicine theory for the treatment of Diabetic kidney disease (DKD) and has been shown to be effective in improving the symptoms of DKD according to the clinical observation.

    AIM OF THE STUDY: To explore the effect of YSTLF on DKD and figure out whether its effects were due to the regulation Sirt6/TGF-β1/Smad2/3 pathway and promoting degradation of TGF-β1.

    MATERIALS AND METHODS: The extract of YSTLF at 1, 2.5 and 5 g/kg was orally administered to C57BLKS/J (db/db) mice for 8 weeks and db/db mice were given valsartan as a positive control. The littermate db/m and db/db mice were given vehicle as the control and model group, respectively. Blood urea nitrogen and serum creatinine were detected and the urinary albumin excretion, urea albumin creatinine ratio was calculated. The histopathological change of renal tissues in each group was determined. Simultaneously, the levels of fibrosis-related proteins and messenger RNA (mRNA) in kidney and high glucose (HG)-induced SV40-MES-13 cells were detected. The roles of YSTLF in regulating of Sirt6/TGF-β1/Smad2/3 signaling pathway were investigated in HG-stimulated SV40-MES-13 cells and validated in db/db mice. Furthermore, the effect of YSTLF on TGF-β1 degradation was investigated in HG-stimulated SV40-MES-13 cells.

    RESULTS: YSTLF significantly improved the renal function in DKD mice. YSTLF dose-dependently attenuated pathological changes and suppressed the expression of type I collagen, alpha smooth muscle actin, type IV collagen, and fibronectin in vitro and in vivo, resulting in ameliorating of renal fibrosis. YSTLF positively regulated Sirt6 expression, while inhibited the activating of TGF-β1/Smad2/3 signaling pathway. TGF-β1 was steady expressed in HG-stimulated SV40-MES-13 cells, whereas was continuously degraded under YSTLF treatment.

    CONCLUSIONS: YSTLF significantly ameliorates renal damages and fibrosis may via regulating Sirt6/TGF-β1/Smad2/3 signaling pathway as well as promoting the degradation of TGF-β1.

    Stover and manure are the main solid waste in agricultural industry. The generation of stover and manure could lead to serious environmental pollution if not handled properly. Composting is the potential greener solution to remediate and reduce agricultural solid waste, through which stover and manure could be remediated and converted into organic fertilizer, but the long composting period and low efficiency of humic substance production are the key constraints in such remediation approach. In this study, we explore the effect of lignocellulose selective removal on composting by performing chemical pretreatment on agricultural waste followed by utilization of biochar to assist in the remediation by co-composting treatment and reveal the impacts of different lignocellulose component on organic fertilizer production. Aiming to discover the key factors that influence humification during composting process and improve the composting quality as well as comprehensive utilization of agricultural solid waste. The results demonstrated that the removal of selective lignin or hemicellulose led to the shift of abundances lignocellulose-degrading bacteria, which in turn accelerated the degradation of lignocellulose by almost 51.2%. The process also facilitated the remediation of organic waste via humification and increased the humic acid level and HA/FA ratio in just 22 days. The richness of media relies on their lignocellulose content, which is negatively correlated with total nitrogen content, humic acid (HA) content, germination index (GI), and pH, but positively correlated with fulvic acid (FA) and total organic carbon (TOC). The work provides a potential cost effective and efficient framework for agricultural solid waste remediation and reduction.

    Zhang X, Wang J, Xiang S, Zhao L, Lv M, Duan Y, et al.
    Am J Chin Med, 2024;52(6):1795-1817.
    PMID: 39347955 DOI: 10.1142/S0192415X24500708
    Diabetic kidney disease (DKD) has become the primary cause of end-stage renal disease (ESRD), causing an urgent need for preventive strategies for DKD. Astragaloside I (ASI), a bioactive saponin extracted from Astragalus membranaceus (Fisch.) Bunge has been demonstrated to possess a variety of biological activities. This study investigates the therapeutic potential of ASI in DKD and the underlying molecular mechanism using db/db mice in vivo and high glucose (HG)-induced SV40-MES-13 cells in vitro. The results indicated that ASI significantly ameliorated renal dysfunction and mitigated the pathological alterations in the renal tissues of db/db mice. Moreover, ASI was found to reduce the levels of renal fibrosis makers and suppress the activation of TGF-β1/Smad2/3 pathway in both db/db mice and HG-induced SV40-MES-13 cells. Furthermore, ASI downregulated HDAC3 expression, upregulated Klotho expression, and enhanced Klotho release. ASI is directly bound to HDAC3, and the beneficial effects of ASI on Klotho/TGF-β1/Smad2/3-mediciated renal fibrosis in DKD were reversed by the HDAC3 agonist ITSA-1. In conclusion, ASI attenuates renal fibrosis in DKD, and may act through concurrently inhibiting HDAC3 and TGF-β1, thereby regulating HDAC3-mediciated Klotho/TGF-β1/Smad2/3 pathway.
  13. Combined effect of salinity and hypoxia on digestive enzymes and intestinal microbiota in the oyster Crassostrea hongkongensis
    Xie Z, Li Y, Xiong K, Tu Z, Waiho K, Yang C, et al.
    Environ Pollut, 2023 Aug 15;331(Pt 2):121921.
    PMID: 37263564 DOI: 10.1016/j.envpol.2023.121921
    Anthropologic activities caused frequent eutrophication in coastal and estuarine waters, resulting in diel-cycling hypoxia. Given global climate change, extreme weather events often occur, thus salinity fluctuation frequently breaks out in these waters. This study aimed to evaluate the combined effects of salinity and hypoxia on intestinal microbiota and digestive enzymes of Crassostrea hongkongensis. Specifically, we sequenced 16 S rRNA of intestinal microbiota and measured the digestive enzymes trypsin (TRS), lipase (LPS) and amylase (AMY) in oysters exposed for 28 days to three salinities (10, 25 and 35) and two dissolved oxygen conditions, normoxia (6 mg/L) and hypoxia (6 mg/L for 12 h, 2 mg/L for 12 h). Oysters in normoxia and salinity of 25 were treated as control. After 28-day exposure, for microbial components, Fusobacteriota, Firmicutes, Bacteroidota, Proteobacteria and Actinobacteriota comprised the majority for all experimental groups. Compared with the control group, the diversity and structure of intestinal microbiota tended to change in all treated groups. The species richness in C. hongkongensis intestine also changed. It was the most significant that high salinity increased Proteobacteria proportion while low salinity and hypoxia increased Fusobacteriota but decreased Proteobacteria, respectively. Additionally, Actinobacteriota was sensitive and changed under environmental stressor (P 
  14. Nano-TiO2 aggravates the adverse effect of pentachlorophenol on antioxidant and immune response in anti-predatory mussels
    Wei S, Sun B, Liu C, Sokolova I, Waiho K, Fang JKH, et al.
    Sci Total Environ, 2023 Oct 01;893:164836.
    PMID: 37321498 DOI: 10.1016/j.scitotenv.2023.164836
    Nano-TiO2 can act as a vector to organic compounds, such as pentachlorophenol (PCP) posing a potential threat to the marine ecosystems. Studies showed that nano pollutant toxicity can be modulated by abiotic factors, but little is known about the potential influence of biotic stressors (such as predators) on the physiological responses to pollutants in marine organisms. We explored the effects of n-TiO2 and PCP on the mussel Mytilus coruscus in the presence of its natural predator, the swimming crab Portunus trituberculatus. Exposure to n-TiO2, PCP, and predation risk showed interactive effects on antioxidant and immune parameters of the mussels. Elevated activities of catalase (CAT), glutathione peroxidase (GPX), acid phosphatase (ACP) and alkaline phosphatase (AKP), suppressed activity of superoxide dismutase (SOD), lower levels of glutathione (GSH) and increased malondialdehyde (MDA) levels indicated dysregulation of the antioxidant system and immune stress induced by single PCP or n-TiO2 exposure. Integrated biomarker (IBR) response values showed the effect of PCP was concentration dependent. Of the two used n-TiO2 sizes (25 and 100 nm), larger particles induced higher antioxidant and immune disturbances indicating higher toxicity possibly due to higher bioavailability. Compared to single PCP exposure, the combination of n-TiO2 and PCP enhanced the imbalance of SOD/CAT and GSH/GPX and led to elevated oxidative lesions and activation of immune-related enzymes. Overall, the combined impacts of pollutants and biotic stress exhibited a greater magnitude of adverse effects on antioxidant defense and immune parameters in mussels. The toxicological effects of PCP were exacerbated in the presence of n-TiO2, and the deleterious impact of these stressors was further amplified under predator-induced risk after prolonged (28 days) exposure. However, the underlying physiological regulatory mechanisms governing the interplay of these stressors and predatory cues on mussels remain elusive, warranting further investigation.

    PMID: 27064256 DOI: 10.1038/ng.3540
    Primary angle closure glaucoma (PACG) is a major cause of blindness worldwide. We conducted a genome-wide association study (GWAS) followed by replication in a combined total of 10,503 PACG cases and 29,567 controls drawn from 24 countries across Asia, Australia, Europe, North America, and South America. We observed significant evidence of disease association at five new genetic loci upon meta-analysis of all patient collections. These loci are at EPDR1 rs3816415 (odds ratio (OR) = 1.24, P = 5.94 × 10(-15)), CHAT rs1258267 (OR = 1.22, P = 2.85 × 10(-16)), GLIS3 rs736893 (OR = 1.18, P = 1.43 × 10(-14)), FERMT2 rs7494379 (OR = 1.14, P = 3.43 × 10(-11)), and DPM2-FAM102A rs3739821 (OR = 1.15, P = 8.32 × 10(-12)). We also confirmed significant association at three previously described loci (P < 5 × 10(-8) for each sentinel SNP at PLEKHA7, COL11A1, and PCMTD1-ST18), providing new insights into the biology of PACG.
  17. Fulltext Precision luminosity measurement in proton-proton collisions at s = 13 TeV in 2015 and 2016 at CMS
    Sirunyan AM, Tumasyan A, Adam W, Andrejkovic JW, Bergauer T, Chatterjee S, et al.
    Eur Phys J C Part Fields, 2021;81(9):800.
    PMID: 34781320 DOI: 10.1140/epjc/s10052-021-09538-2
    The measurement of the luminosity recorded by the CMS detector installed at LHC interaction point 5, using proton-proton collisions at s = 13 TeV in 2015 and 2016, is reported. The absolute luminosity scale is measured for individual bunch crossings using beam-separation scans (the van der Meer method), with a relative precision of 1.3 and 1.0% in 2015 and 2016, respectively. The dominant sources of uncertainty are related to residual differences between the measured beam positions and the ones provided by the operational settings of the LHC magnets, the factorizability of the proton bunch spatial density functions in the coordinates transverse to the beam direction, and the modeling of the effect of electromagnetic interactions among protons in the colliding bunches. When applying the van der Meer calibration to the entire run periods, the integrated luminosities when CMS was fully operational are 2.27 and 36.3 fb - 1 in 2015 and 2016, with a relative precision of 1.6 and 1.2%, respectively. These are among the most precise luminosity measurements at bunched-beam hadron colliders.

    In 2008, we published the first set of guidelines for standardizing research in autophagy. Since then, this topic has received increasing attention, and many scientists have entered the field. Our knowledge base and relevant new technologies have also been expanding. Thus, it is important to formulate on a regular basis updated guidelines for monitoring autophagy in different organisms. Despite numerous reviews, there continues to be confusion regarding acceptable methods to evaluate autophagy, especially in multicellular eukaryotes. Here, we present a set of guidelines for investigators to select and interpret methods to examine autophagy and related processes, and for reviewers to provide realistic and reasonable critiques of reports that are focused on these processes. These guidelines are not meant to be a dogmatic set of rules, because the appropriateness of any assay largely depends on the question being asked and the system being used. Moreover, no individual assay is perfect for every situation, calling for the use of multiple techniques to properly monitor autophagy in each experimental setting. Finally, several core components of the autophagy machinery have been implicated in distinct autophagic processes (canonical and noncanonical autophagy), implying that genetic approaches to block autophagy should rely on targeting two or more autophagy-related genes that ideally participate in distinct steps of the pathway. Along similar lines, because multiple proteins involved in autophagy also regulate other cellular pathways including apoptosis, not all of them can be used as a specific marker for bona fide autophagic responses. Here, we critically discuss current methods of assessing autophagy and the information they can, or cannot, provide. Our ultimate goal is to encourage intellectual and technical innovation in the field.
