Harmony with nature: Disentanglement the influence of ecological perception and adaptation on sustainable development and circular economy goals in country.

From the perspective of ecosystem attributes, this research was conducted to explore the impact of people's adaptation and response to their perception of environmental risks on their preference for sustainable development strategies and the realization of a circular economy based on Social Judgment Theory and the Value-Belief-Norm (VBN) theory. To achieve the goal, three substudies were conducted using questionnaire surveys-the first substudy aimed to examine the influence of ecological attributes on environmental risk perception (ERP). The second substudy attempted to understand the intricate connection between ERP and justice, while the third study explored the relationship between justice and SDS (sustainable development strategies) and CEG (realization of a circular economy). The results indicate the following: (1) The first substudy reveals that ecological attributes impact environmental risk perception (ERP), with different environmental values exerting distinct influences. (2) The second substudy suggests that ERP facilitates the realization of social, environmental, and ecological justice, but people's preference for a specific economic growth strategy will affect their tendency to realize justice. (3) The third substudy shows that sustainability strategies (i.e., sustainable production, consumption, and use) mediate the relationship between justice and circular economy goals (CEG). Among the three strategies, sustainable use plays the most significant mediating role. The research outcomes underscore the importance of prioritizing sustainable use in future research in theory and practice.

Study on the mechanism of enhanced anaerobic ammonia oxidation performance by extracellular electron acceptor biochar.

ABSTRACTAnaerobic ammonia oxidation process has the advantages of energy and cost reduction, therefore, it has been considered as one of the main alternatives to conventional biological denitrification process in recent years. Biochar has been applied in the anammox process for nitrogen removal efficiency. But, due to its extracellular electron transfer capacity and abundance of redox-specific functional groups, which served as extracellular electron acceptor to anaerobically oxidize NH4+ is still controversy. In this study, the anaerobic ammonia oxidation was investigated when biochar was used as electron acceptor in the wastewater. According to the optimal process variables determined in the batch tests, when the influent NH4+-N concentration in the anaerobic ammonia oxidation reaction was 30-50 mg/L and the biochar dosing was at 10 g/L, it showed some promotion in the long-term experiments. The anaerobic ammonia oxidation process with biochar as the electron acceptor reached more than 60% NH4+-N removal efficiency in the system, and the ΔNO3--N/ΔNH4+-N ratio reached 0.19 which tended to the theoretical value. After 20 days, the voltage in the system keeps fluctuating about 4 mV, indicated that the functional bacteria using biochar as the electron acceptor gradually dominated the system. In addition, the abundance of norank_f__norank_o__SBR1031 in the Chloroflexi phylum has increased significantly at 29.92%, while the abundance of the major genus Candidatus_Kuenenia in AnAOB has decreased slightly at 11.47%.

Performance of short-cut denitrifying phosphorus removal and microbial community structure in the A2SBR process.

ABSTRACTAcclimatization of short-cut denitrifying polyphosphate accumulating organisms (SDPAOs), metabolic mechanism, and operating parameters were analyzed to investigate the performance of the anaerobic/anoxic sequencing batch reactor (A2SBR) process. The high-throughput sequencing technology was employed to explore the microbial community structures of activated sludge systems. The experimental results illustrated that SDPAOs were successfully enriched with three-phase inoculation for 36 days. The removal rates of TP and NO2--N were 93.22% and 91.36%, respectively, under the optimal parameters of a pH of 7.5, an SRT of 26 days, a temperature of 24 ℃ and a COD of 200.00 mg·L-1 using acetate as the carbon source. In the anaerobic stage, 82.20% external carbon source was converted into 88.78 mg·g-1 PHB, and the removal rate of NO2--N in the anoxic stage was characterized by ΔNO2--N/ΔPHB, anoxic ΔP/ΔPHBeffective was 0.289, which was higher than anaerobic ΔP/ΔCODeffective of 0.203. Ignavibacterium and Povalibacter with significant phosphorus removal ability were the dominant bacterial genera. The nitrogen and phosphorus removal could be realized simultaneously in an anaerobic/anoxic sequencing batch reactor. Therefore, this study provided an important understanding of the removal of nitrogen and phosphorus from low-carbon nitrogen wastewater.

Detection of aberrant DNA methylation patterns in sperm of male recurrent spontaneous abortion patients.

Aberrant DNA methylation patterns in sperm are a cause of embryonic failure and infertility, and could be a critical factor contributing to male recurrent spontaneous abortion (RSA). The purpose of this study was to reveal the potential effects of sperm DNA methylation levels in patients with male RSA. We compared sperm samples collected from fertile men and oligoasthenospermia patients. Differentially methylated sequences were identified by reduced representation bisulfite sequencing (RRBS) methods. The DNA methylation levels of the two groups were compared and qRT-PCR was used to validate the expression of genes showing differential methylation. The results indicated that no difference in base distribution was observed between the normal group and the patient group. However, the chromosome methylation in these two groups was markedly different. One site was located on chromosome 8 and measured 150 bp, while the other sites were on chromosomes 9, 10, and X and measured 135 bp, 68 bp, and 136 bp, respectively. In particular, two genes were found to be hypermethylated in these patients, one gene was DYDC2 (placed in the differential methylation region of chromosome 10), and the other gene was NXF3 (located on chromosome X). Expression levels of DYDC2 and NXF3 in the RSA group were significantly lower than those in the normal group (P < 0.05). Collectively, these results demonstrated that changes in DNA methylation might be related to male RSA. Our findings provide important information regarding the potential role of sperm DNA methylation in human development.

Paternal hypoxia exposure impairs fertilization process and preimplantation embryo development.

Environmental hypoxia exposure causes fertility problems in human and animals. Compelling evidence suggests that chronic hypoxia impairs spermatogenesis and reduces sperm motility. However, it is unclear whether paternal hypoxic exposure affects fertilization and early embryo development. In the present study, we exposed male mice to high altitude (3200 m above sea level) for 7 or 60 days to evaluate the effects of hypoxia on sperm quality, zygotic DNA methylation and blastocyst formation. Compared with age-matched controls, hypoxia-treated males exhibited reduced fertility after mating with normoxic females as a result of defects in sperm motility and function. Results of in vitro fertilization (IVF) experiments revealed that 60 days' exposure significantly reduced cleavage and blastocyst rates by 30% and 70%, respectively. Immunohistochemical staining of pronuclear formation indicated that the pronuclear formation process was disturbed and expression of imprinted genes was reduced in early embryos after paternal hypoxia. Overall, the findings of this study suggested that exposing male mice to hypoxia impaired sperm function and affected key events during early embryo development in mammals.

The complete mitochondrial genome of a non-biting midge Polypedilum unifascium (Tokunaga, 1938) (Diptera: Chironomidae).

The complete mitochondrial genome of Polypedilum unifascium (Diptera: Chironomidae) was determined by Illumina sequencing technology. The whole mitogenome is 16,452 bp in length with an A + T bias of 79.3%, and contains 13 protein-coding genes (PCGs), 22 transfer RNAs (tRNAs), and two ribosomal RNAs (rRNAs). All PCGs start with ATN codon and use TAA as the stop codon. Gene arrangement of the 13 PCGs is identical to that of other known Chironomidae mitochondrial genomes. The resultant Bayesian inference and maximum-likelihood trees based on the sequence data of 13 PCGs support its close relationship with P. vanderplanki.

Evodiamine inhibits high-fat diet-induced colitis-associated cancer in mice through regulating the gut microbiota / 中西医结合学报

OBJECTIVE@#High-fat diet is one of the main risk factors that disrupt the balance of gut microbiota, which eventually will induce colorectal cancer (CRC). Evodiamine (EVO) is a wildly used multifunctional traditional Chinese medicine extract. In this study, we investigated the role of gut microbiota in high-fat diet-propelled CRC and the potential of EVO for CRC chemoprevention.@*METHODS@#Gut microbiota, serum d-lactic acid and endotoxin from 38 patients with colon cancer and 18 healthy subjects were detected by quantitative real-time polymerase chain reaction and enzyme-linked immunosorbent assay (ELISA). In addition, body mass index, phospho-signal transducer and activator of transcription 3 (p-STAT3) expression in cancer tissues and paracancerous tissues were detected by immunohistochemistry. A mouse intestinal inflammatory tumor model was established by azomethane/sodium dextran sulfate, followed by treatment with EVO and 5-aminosalicylic acid (ASA). Gut microbiota and inflammatory factors were detected by quantitative polymerase chain reaction, while serum d-lactic acid and endotoxin were detected by ELISA. Furthermore, cell proliferation, cell apoptosis, and interleukin (IL)-6/STAT3/P65 pathway were evaluated by 5-ethynyl-2'-deoxyuridine, terminal-deoxynucleotidyl transferase-mediated nick-end labeling, and Western blot assays.@*RESULTS@#In patients with colon cancer, the numbers of Enterococcus faecalis and Escherichia coli were increased, while those of Bifidobacterium, Campylobacter and Lactobacillus were decreased. Serum endotoxin and d-lactic acid levels and p-STAT3 levels were significantly increased. In the mouse model, both EVO and ASA inhibited tumor formation, decreased the proliferation of tumor cells, and induced apoptosis of tumor cells. Compared with the control group, the numbers of E. faecalis and E. coli were decreased, while Bifidobacterium, Campylobacter and Lactobacillus numbers were increased. In the EVO group, serum endotoxin and d-lactic acid levels and inflammatory factors were significantly decreased. Further, the IL6/STAT3/P65 signaling pathway was inhibited in the EVO group.@*CONCLUSION@#EVO may inhibit the occurrence of colon cancer by regulating gut microbiota and inhibiting intestinal inflammation. The potential mechanism involves inhibition of the IL6/STAT3/P65 signaling pathway, revealing its potential therapeutic significance in clinical applications.

Objective:To explore the effect of transcatheter chemoembolization (TACE) on recurrence and survival time of hepatitis B virus (HBV)-related hepatocellular carcinoma (HCC) following curative resection.Methods:Of 724 HBV-related HCC patients who underwent curative resection in the Third Affiliated Hospital of Naval Military Medical University from October 2009 to August 2010 were retrospectively analyzed. Patients who underwent resection only and no recurrence within 3 months after surgery were classified into control group, while those received adjuvant TACE were classified into intervention group. The patients were further divided into 4 sub-groups according to tumor size, tumor number and tumor thrombus which were defined as risk factors for recurrence. Tumor diameter ≤5 cm with low or high risk factors (tumor number ≥2 or presence tumor thrombus) were in group 1 and group 2 respectively, tumor diameter >5 cm with low or high risk factors for recurrence were in group 3 and group 4 respectively.Results:A total of 354 patients were classified in the control group and 370 patients were classified in the TACE group. Adjuvant TACE showed an overall survival benefit in patients with tumor diameter >5 cm and presenting high risk factors, the 1-, 3-, and 5-year cumulative survival rates were 90.1%, 67.6%, and 46.5%, respectively, for the lip-TACE group 83.3%, 52.4%, and 33.3%, respectively, for the control group ( P<0.05). Patients with the tumor diameter ≤5 cm, there was no significant difference in cumulative survival between the TACE group and the control group regardless of the risk level ( P>0.05). There was no significant difference in recurrence curve between TACE group and control group in each stratum. Conclusions:Adjuvant TACE had no preventive effect on recurrence, but TACE can prolong the survival time of HCC patients with high risk factors for recurrence.

Eosinophilic granulomatous polyangiitis with allergic bronchopulmonary aspergillosis as a comorbidity: a case report and literature review / 中华风湿病学杂志

Objective:To explore the clinical characteristics, diagnosis and treatment of allergic bronchopulmonary aspergillosis(ABPA) with eosinophilic granulomatous with polyvasculitis(EGPA) as a comorbidity.Methods:We collected the clinical data of a patient with EGPA who sought treatment with ABPA as a comorbidity. We summarized the diagnosis and treatment process of the patient, and reviewed the literature. After that, we discussed the relationship between the pathogenesis of ABPA and EGPA and the diagnosis and treatment experience.Results:A 61-year-old male patient suffered from repeated coughing, expectoration, hemoptysis, wheezing. His blood eosinophils count and immunoglobulin (Ig)E level were elevated. He was tested positive for aspergillus fumigatus. His Computer Tomography (CT) showed pulmonary nodules and bronchiectasis. He was diagnosed as ABPA. He also suffered limb numbness, sinusitis, and renal dysfunction and was diagnosed as EGPA. His condition improved after treatment with glucocorticoids, immunosuppressants and antifungal agents. We reviewed the relevant literature and retrieved 10 case reports, of which 5 cases were diagnosed as ABPA first and then EGPA, 3 cases were diagnosed as EGPA first and then ABPA, 2 cases were diagnosed simultaneously. We found that there was a certain correlation between them in the pathogenesis, and the main treatment is glucocorticoids, immunosuppressants and antifungal drugs.Conclusion:ABPA with EGPA as a comorbidity is rarely reported, which reminds us that when diagnosing one of the diseases in clinical work, we should be alert to the coexistence of another disease to avoid misdiagnosis.

Function and transcriptomic dynamics of Sertoli cells during prospermatogonia development in mouse testis.

In mammals, spermatogonial stem cells (SSCs) arise from a subpopulation of prospermatogonia during neonatal testis development. Currently, molecular mechanisms directing the prospermatogonia to spermatogonial transition are not well understood. In the study, we found that reducing Sertoli cells number by Amh-cre mediated expression of diphtheria toxin (AC;DTA) in murine fetal testis caused defects in prospermatogonia fate decisions. Histological and immunohistochemical analyses confirmed that Sertoli cells loss occurred at embryonic day (E) 14.5. Prospermatogonia maintained mitotic arrest at E16.5 in control animals, in contrast, 13.4% of germ cells in AC;DTA testis reentered cell cycle and expressed gH2A.X and Sycp3, indicating the commitment to meiosis. After birth, the number of prospermatogonia resuming mitosis was significantly affected by Sertoli cell loss in AC;DTA animals. Lastly, we isolated primary Sertoli cells using a Sertoli cell specific GFP reporter line and showed dynamics of Sertoli cell transcriptomes at E12.5, E13.5, E16.5 and P1. By further analysis, we revealed unique gene expression patterns and potential candidate genes regulating Sertoli cell development and likely mediating interactions between Sertoli cells, prospermatogonia and other testicular cells.

Advances in research on aquaporins in medical helminthes / 中国血吸虫病防治杂志

Aquaporins (AQPs) are a class of membrane intrinsic proteins in medical helminthes that specifically mediate the transmembrane transport of water or other solute molecules. Previous studies have demonstrated that AQPs play a critical role in promoting the transmembrane transport of water, osmoregulation, uptake of nutrients, release of toxic metabolic products and transport of antiparasitic drugs, which may serve as promising vaccine candidates and drug targets for parasitic diseases. This review describes the structural characteristics of AQPs in medical helminthes, and discusses the feasibility of these AQPs as antihelminth vaccine candidates and drug targets, so as to provide insights into the development of novel vaccines and drugs against parasitic diseases.

Advances in research of protein kinase A in parasites: a review / 中国血吸虫病防治杂志

PKA plays an important role in the cAMP signaling pathway, and is involved in various life activities of parasites. Therefore, investigating the role of PKA in the life activities of parasites may provide insights into the development of novel anti-parasitic targets. The review mainly describes the structure and function of PKA and its role in life activities of parasites.

Transcriptomic Features of Echinococcus granulosus Protoscolex during the Encystation Process

Cystic echinococcosis (CE) is a zoonotic infection caused by Echinococcus granulosus larvae. It seriously affects the development of animal husbandry and endangers human health. Due to a poor understanding of the cystic fluid formation pathway, there is currently a lack of innovative methods for the prevention and treatment of CE. In this study, the protoscoleces (PSCs) in the encystation process were analyzed by high-throughput RNA sequencing. A total of 32,401 transcripts and 14,903 cDNAs revealed numbers of new genes and transcripts, stage-specific genes, and differently expressed genes. Genes encoding proteins involved in signaling pathways, such as putative G-protein coupled receptor, tyrosine kinases, and serine/threonine protein kinase, were predominantly up-regulated during the encystation process. Antioxidant enzymes included cytochrome c oxidase, thioredoxin glutathione, and glutathione peroxidase were a high expression level. Intriguingly, KEGG enrichment suggested that differentially up-regulated genes involved in the vasopressin-regulated water reabsorption metabolic pathway may play important roles in the transport of proteins, carbohydrates, and other substances. These results provide valuable information on the mechanism of cystic fluid production during the encystation process, and provide a basis for further studies on the molecular mechanisms of growth and development of PSCs.

Association of serum uric acid with thyroid function in health check-up participants / 中华医学杂志(英文版)

BACKGROUND@#The relationship of uric acid (UA) with the thyroid function among healthy individuals remains unclear. We aimed to examine the relationship between UA contents and thyroid hormone levels in healthy Chinese individuals.@*METHODS@#This was a cross-sectional study of 1186 Chinese adults (736 men and 450 women) who underwent a health check-up at the Huadong Hospital Affiliated to Fudan University (Shanghai, China) between January 1, 2010 and July 31, 2018. Clinical and thyroid hormone levels were compared in different UA groups (in male and menopause women groups, MG1: UA < 5 mg/dL; MG2: 5 mg/dL ≤ UA< 7 mg/dL; and MG3: UA ≥ 7 mg/dL; in female groups, FG1 to FG3 represent the UA levels of <4 mg/dL, 4 mg/dL ≤ UA< 6 mg/dL, and ≥6 mg/dL, respectively). In addition, natural cubic spline regression, together with Pearson correlation analysis, was performed in investigating the correlation of UA with thyroid hormones.@*RESULTS@#After adjusting for confounding factors, low levels of UA (for males, UA < 5.30 mg/dL; for females, UA < 4.05 mg/dL) were negatively correlated with free triiodothyronine (FT3) both in men and women. UA levels between 4.83 and 6.06 mg/dL may act to protect FT3 in women, while UA levels between 6.39 and 7.09 mg/dL may protect FT3 in men. FT3 levels of low-range UA group reduced compared with mid-range UA and the high-range UA groups in both men and women.@*CONCLUSIONS@#Our results provide epidemiologic evidence to support the negative correlation between low UA contents and FT3 in the Chinese Han population, suggesting that the reduced UA contents may serve as the risk factor to predict poor thyroid function in Chinese individuals.

Protective effect of necrostatin1 on the damage of pancreas islet cells induced by TNFα / 中南大学学报(医学版)

OBJECTIVES@#To investigate whether necrostatin-1 (Nec-1) can protect islet cells from the damage induced by TNF-α.@*METHODS@#After isolation and purification, the neonatal porcine islet cell clusters (NICCs) were divided into 3 groups (islets 10 000 IEQ/group): a Nec-1 group (Nec-1+TNF-α was added to the culture medium), a TNF-α group (TNF-α was added to the culture medium), and a control group (pure medium). The number of cells was observed after 48 h of co-culture. The cell death was evaluated by AO/EB staining. Insulin secretion and DNA of islets were detected by chemiluminescence and nucleic acid quantitative analysis. RT-PCR assay was used to examine the mRNA expressions of insulin gene, glueogan gene and somatostatin gene. Flow cytometry analysis was used to detect the viability of B cells.@*RESULTS@#The number of islets in Nec-1 group, TNF-α group and the control group were (8 425±2 187), (4 325±778), and (7 122±1 558) IEQ, respectively. Compared to the other two groups, the number of dead cells in TNF-α group was greatly increased. The insulin/DNA values in the Nec-1 group, TNF-α group and blank control group were (13.21±3.15), (2.47±0.45), and (7.44±0.97) mIU/mg, respectively. Compared to the TNF-α group and the control group, the mRNA relative expression levels of insulin gene (6.73±1.07), glucagon gene (10.13±1.98), somatostatin gene (8.57±1.11) were significantly increased in the Nec-1 group (all <0.05), the rate of live cells (97.32±1.87)% and live B cells (90.86±3.68)% were increased significantly in the Nec-1 group (all <0.05).@*CONCLUSIONS@#TNF-α can induce neonatal porcine islet cells damage, which is attenuated in the presence of Nec-1. Nec-1 can increase the content of endocrine cells in NICCs.
