RESUMO

AIM: To determine the effectiveness of brief reminiscence-based psychosocial interventions in alleviating psychological distress in cancer patients. BACKGROUND: Cancer patients suffer tremendous psycho-spiritual pain, which affects their quality of life. Brief reminiscence-based psychosocial interventions have demonstrated positive effects on the mental health of cancer patients; however, the efficacy of these interventions has been inconsistent. DESIGN: A systematic review and meta-analysis. METHODS: This review was conducted and reported in accordance with the PRISMA 2020 checklist provided by the EQUATOR network. The Cochrane Library, Web of Science, PsycINFO, PubMed, Embase, CINAHL and Scopus databases were systematically searched from inception to 27 November 2022 to identify randomised controlled trials (RCTs) published in English. RESULTS: Twenty studies involving 1744 cancer participants were included. The meta-analysis showed statistically significant effects of brief reminiscence-based psychosocial interventions on hope, anxiety and depression at post-intervention. A separate analysis revealed that brief reminiscence-based psychosocial interventions had a sustainable effect on hope, spiritual well-being, anxiety and depression at 1 month after the intervention. However, no statistically significant effect on quality of life was found in our study either immediately after the intervention or at 1 month. CONCLUSIONS: Brief reminiscence-based psychosocial interventions can significantly reduce anxiety and depressive symptoms and improve hope and spiritual well-being in cancer patients. RELEVANCE TO CLINICAL PRACTICE: This study further supports that brief reminiscence-based psychosocial interventions should be incorporated into the routine care of cancer patients to address their psychosocial distress. PATIENT OR PUBLIC CONTRIBUTION: All authors of this article contributed to the study conception and design. All authors of the included studies provided original data for this paper.

RESUMO

BACKGROUND: Although peritoneal lavage with povidone-iodine (PVPI) is frequently performed after surgery on the gastrointestinal tract, the effects of PVPI on the intestinal epithelial barrier are unknown. The purpose of this study was to investigate the effects of abdominal irrigation with PVPI on the intestinal epithelial barrier in a colorectal cancer (CRC)-induced rat model. MATERIALS AND METHODS: The CRC model was induced in rats with azoxymethane and dextran sodium sulfate. Next, a total of 24 male CRC-induced rats were randomly divided into three groups (n = 8): (1) a sham-operated group, (2) an NS group (peritoneal lavage 0.9% NaCl), and (3) a PVPI group (peritoneal lavage with 0.45%-0.55% PVPI). The mean arterial pressure was continuously monitored throughout the experiment. The levels of plasma endotoxin and D-lactate, blood gases, and protein concentration were measured. The ultrastructural changes of the epithelial tight junctions were observed by transmission electron microscopy. RESULTS: The mean arterial pressure after peritoneal lavage was lower in the PVPI group than that in the NS group. The protein concentration and levels of endotoxin and D-lactate were higher in the PVPI group than they were in the PVPI group. In addition, PVPI treatment resulted in a markedly severe metabolic acidosis and intestinal mucosal injury compared with NS rats. CONCLUSIONS: Peritoneal lavage with PVPI dramatically compromises the integrity of the intestinal mucosa barrier and causes endotoxin shock in CRC rats. It is unsafe for clinical applications to include peritoneal lavage with PVPI in colorectal operations.

RESUMO

OBJECTIVE: To evaluate the glycated hemoglobin (HbA1c), blood pressure, self-efficacy, and quality of life efficacy of using telecare services for community-dwelling people with diabetes. METHODS: Cochrane Library, Web of Science, PsycINFO, PubMed, EMBASE, CINAHL, and Scopus databases were systematically searched from their inception dates to June 22, 2023. Two evaluators independently selected and evaluated eligible studies. A protocol was registered in PROSPERO. RESULTS: An analysis of 17 studies that included 3586 subjects showed that telecare significantly improved the management of patients with diabetes. Compared to controls, intervention care had significant benefits regarding HbA1c (MD = -0.30, 95 % CI = -0.44 - -0.17, 16 studies), systolic blood pressure (MD = -2.45, 95 % CI = -4.53 - -0.36, P = 0.02), self-efficacy (MD = 0.36, 95 % CI = 0.04 - 0.67, P = 0.03) and quality of life (MD = 0.37, 95 % CI = 0.05 - 0.70, P = 0.02). However, diastolic blood pressure (MD = -1.37, 95 % CI = -3.34 - -0.61, P = 0.17) was not found to be significantly affected. CONCLUSIONS: Telecare is effective in improving self-management among community-dwelling people with diabetes, suggesting an effective means for them to achieve self-management.

RESUMO

Asian honeybees (Apis cerana) play a crucial role as pollinators to service for the ecological stability. However, their proliferation and growth are significantly impacted by environmental temperature stress. This study delves into the function of the Apis cerana vesicular inhibitory amino acid transporter gene (AcVIAAT) in safeguarding Asian honeybees against high-temperature stress. The AcVIAAT gene exhibits positive responsiveness in honeybees subjected to varying thermal conditions by triggering the genes associated with oxidative stress. Molecular docking, co-immunoprecipitation, and ELISA verify the capacity of the AcVIAAT protein to interact with γ-aminobutyric acid (GABA), a key inhibitory neurotransmitter. Administering GABA to honeybees significantly improves their survival rate under high-temperature stress and also simultaneously upregulating oxidative stress-related genes. Therefore, these findings reveal that the AcVIAAT gene enhances the thermoregulatory capacity of honeybees by modulating oxidative stress-related genes through facilitating GABA transport. The characterization of six non-synonymous SNPs in the AcVIAAT gene among A.cerana populations distributed across both the northern and southern regions indicates a potential association between gene variation and environmental adaptation. Our results contribute to elucidating the molecular mechanisms underlying high-temperature tolerance in Asian honeybees and provide a promising genetic marker for enhancing heat tolerance through genetic improvement.

RESUMO

Developing effective long-term sperm storage strategies to maintain activity requires an understanding of the underlying spermatophore developmental phase in drones. Here we compared the developmental processes and metabolites about seminal vesicles of drones from different parentages (0-24 d)in honeybee colonies, including mated queens, virgin queens, and worker bees. The results showed a similar developmental trend of seminal vesicles in thethree groups of drones on the whole, although there were significant differences in developmental levels, as well as in other indicators. Correlation analysis showed significant positive correlations between seminal vesicle width and sperm viability. The metabolomics of the seminal vesicles in drones from mated queens showed differences of the metabolites in each stage. Particularly, squalene identified among them was validated a protective effect on sperm vitality in vitro experiments. Together the results of these assays support that there were significant differences in the developmental levels of seminal vesicles among the three groups of drones in honeybees, wherein a significant correlation between sperm viability and the developmental levels of seminal vesicles were dissected. The metabolomics analysis and semen storage experiments in vitro display signatures of squalene that may act as an effective protective agent in maintaining sperm viability. Collectively, our findings indicate that spermatophore development in drones provides metabolite support, which contributes to research on the differences of sperm viability among drones in the future.

RESUMO

BACKGROUND: In recent years, virtual reality technology has developed the potential to help in the early detection of mild cognitive impairment (MCI). However, integrative evidence of its detection performance for mild cognitive impairment is lacking, and meta-analysis or systematic reviews are required to further determine the effectiveness of virtual reality technology in screening for MCI. METHODS: Literature searches were performed for MCI screening tests in the Cochrane Library, Web of Science, PsycINFO, PubMed, EMBASE, CINAHL, and Scopus. The primary outcome was the performance of VR tests for MCI detection. A protocol for this systematic review was registered in PROSPERO (Registration number: CRD42022302139). RESULTS: A total of 14 studies in 13 reports were eventually included. The combined data with the bivariate random-effects model gave a summary point of 0.89 sensitivity (95 % confidence interval [CI]: 0.82-0.94) and 0.91 specificity (95 % CI: 0.82-0.96). The SROC curve was plotted, the DOR was 79.25 (95 % CI: 22.59-277.99), and the AUC was 0.95 (95 % CI: 0.93-0.97). CONCLUSIONS: Virtual reality-based tests have shown considerable detection performance in detecting MCI, and therefore, virtual reality-based tests can serve as recommended screening methods. Future studies can consider longitudinal assessment and follow-up programs to identify progressive changes.

RESUMO

Apis laboriosa is the largest honeybee that lives mainly on cliff faces, with strong migratory ability. In this study, we firstly sequenced and assembled two complete mitochondrial genomes of A. laboriosa isolated from two distant locations in China (Chongqing and Shangri-La regions). Combined with the published mitochondrial genome of A. laboriosa from Nepal, comparative genomic analyses were conducted to gain insight into the genetic diversity of giant honeybees from different geographical distributions. The mitochondrial genomes of A. laboriosa from Chongqing and Shangri-La regions were 15,579 and 15,683 bp in length, respectively, both larger than that from Nepal with the length of 15,510 bp. Three mitochondrial genomes all harbor 37 common genes and present the same AT bias and the frequency of codon usage. However, the fragments including COX1, SSUrRNA, LSUrRNA, and the AT-rich region of the mitochondrial genome from Shangri-La region demonstrate distinctive insertions and deletions compared to those from Chongqing and Nepal regions. Phylogenetic trees of mitochondrial genomes show that A. laboriosa from Chongqing is most closely related to that from Nepal, rather than to Shangri-La. Genetic distance between Shangri-La and Chongqing or Nepal was even larger than that between the various subspecies of Apis mellifera. Overall, these results unmark that A. laboriosa in different geographical distributions can exhibit high genetic diversity at the mitochondrial genomic level, and therein, A. laboriosa from Shangri-La may be the subspecies. All these studies will contribute to our understanding of the geographical distribution and genetic differentiation of black giant honeybee in Asian region.

RESUMO

Radiation exposure is an on going and serious threat in military and public health concern. There is an unmet need for effective preventative or mitigative treatments against radiation-induced injuries. The handful of Food and Drug Administration in the US approved radiation protection agents cannot be widely used due to their side effects. Some natural nontoxic compounds such as bee products have been reported to prevent and treat radiation-induced injuries (e.g. scavenging free radicals, inhibiting cell apoptosis and reducing DNA damage), indicating that they may be a potential option as a safe radioprotective agent. Bee products are nontoxic and have no known side effects on the human body, and are effective in the field of radiation protection. They are expected to be interesting drug candidates for preventing and treating radiation-induced injuries. This article reviews the prevention and treatment of bee products on radiation-induced injuries.

RESUMO

Apis cerana abansis, widely distributed in the southeastern margin of the Qinghai-Tibet Plateau, is considered an excellent model to study the phenotype and genetic variation for highland adaptation of Asian honeybee. Herein, we assembled and annotated the chromosome-scale assembly genome of A. cerana abansis with the help of PacBio, Illumina and Hi-C sequencing technologies in order to identify the genome differences between the A. cerana abansis and the published genomes of different A. cerana strains. The sequencing methods, assembly and annotation strategies of A. cerana abansis were more comprehensive than previously published A. cerana genomes. Then, the intraspecific genetic diversity of A. cerana was revealed at the genomic level. We re-identified the repeat content in the genome of A. cerana abansis, as well as the other three A. cerana strains. The chemosensory and immune-related proteins in different A. cerana strains were carefully re-identified, so that 132 odorant receptor subfamilies, 12 gustatory receptor subfamilies and 22 immune-related pathways were found. We also discovered that, compared with other published genomes, the A. ceranaabansis lost the largest number of chemoreceptors compared to other strains, and hypothesized that gene loss/gain might help different A. cerana strains to adapt to their respective environments. Our work contains more complete and precise assembly and annotation results for the A. cerana genome, thus providing a resource for subsequent in-depth related studies.

RESUMO

BACKGROUND: Microsporidia Nosema bombycis is the destructive pathogen in the production of sericulture. The Tc1/mariner elements belong to important component of DNA transposon. METHODS: The genomic data of N. bombycis and related Nosema species were screened to identify the Tc1-like elements and analyzed the phylogenetic relationship, based on bioinformational analysis. High-throughput data of transcriptomes and small RNAs were used to evaluate the expressed level and potential rasiRNAs for the Tc1-like elements of N. bombycis. RESULTS: Twelve complete Tc1-like elements belonging to DD34,E clade is confirmed in the whole genome of N. bombycis, and divided into two branches. Six of them are sole in N. bombycis and thereby would be the molecular marker to differentiate this species from others Nosema spp. Most of the elements have the transcriptional active and are the source of sRNAs. CONCLUSION: Abundant Tc1-like elements in N. bombycis reflect the expansion of transposons for this genomic characters, comparing with others Nosema spp. The finding of distribution, phylogeny and potential functional activity for Tc1Nbs in N. bombycis will help understanding the role of the DNA transposon in genomic evolution of microsporidia.

RESUMO

Aims: Given their regulatory roles in gene expression, microRNAs play an important role in tumorigenesis. The current study aimed to explore the function and the related mechanisms of miR-616 in hepatocellular carcinoma (HCC).Methods: The expression of miR-616 was detected using quantitative real-time polymerase chain reaction (qRT-PCR). Chi-square test was applied to estimate the association of miR-616 with clinical characteristics of HCC patients. Cell transfection was performed by Lipofectamine® 2000. MTT assay was used to detect cell proliferation, whereas cell motility was estimated using Transwell assay. The protein expression was detected using western blot.Results: MiR-616 was significantly up-regulated in HCC tissues and cells (p < .05 for all). Moreover, its elevated expression was positively correlated with lymph node metastasis (p = .008) and TNM stage (p = .012). Knockdown of miR-616 resulted in decreased cell proliferation, migration and invasion. Moreover, the inhibition of miR-616 significantly suppressed PI3K/AKT pathway. The bioinformatics analysis and luciferase reporter assay suggested that PTEN was a targeted gene of miR-616. PTEN had the capacity to reverse the oncogenic function of miR-616 in HCC.Conclusion: MiR-616 activates PI3K/AKT pathway through suppressing PTEN expression, thus promoting the progression of HCC.

RESUMO

OBJECTIVE: The purpose of this study was to investigate the function of APC polymorphisms (D1822V and E1317Q) on the transition from polyps to colorectal cancer (CRC). METHODS: 259 patients with polyps were included in the study. APC polymorphisms were genotyped via polymerase chain reaction (PCR) and subsequent sequencing. χ2 test was performed to analyze the relationship of APC polymorphisms or CRC occurrence with clinical features. COX regression was used to find out risk factors for CRC. Hazard ratio (HR) and 95% confidence interval (CI) represented the risk of CRC. RESULTS: Clinical information on sex, regular physical activity, smoking history, alcohol use and polyps types was recorded. Neither D1822V nor E1317Q polymorphism was associated with these factors. In following analysis, we found significant difference in the frequency of males between CRC and non-CRC patients (87.4% vs. 58.7%, P < 0.001). Distinct difference in the distribution of D1822V polymorphism was also observed between CRC and non-CRC patients (P = 0.001). In COX analysis, sex was identified as a risk factor for transition from polyps to CRC (HR = 2.442, 95%CI = 1.281-4.654). D1822V polymorphism tended to inhibit the transition process (HR = 0.286, 95%CI = 0.170-0.480). However, E1317Q seemed to have no significant effect on this process (HR = 1.042, 95%CI = 0.676-1.606). CONCLUSION: In a word, APC D1822V polymorphism has strong effect on the transition from polyps to CRC.

RESUMO

The geographic and biological diversity of China has resulted in the differential adaptation of the eastern honeybee, Apis cerana, to these varied habitats. A. cerana were collected from 14 locations in China. Their genomes were sequenced, and nucleotide polymorphisms were identified at more than 9 million sites. Both STRUCTURE and principal component analysis placed the bees into seven groups. Phylogenomic analysis groups the honeybees into many of the same clusters with high bootstrap values (91%-100%). Populations from Tibet and South Yunnan are sister taxa and together represent the earliest diverging lineage included in this study. We propose that the evolutionary origin of A. cerana in China was in the southern region of Yunnan Province and expanded from there into the southeastern regions and into the northeastern mountain regions. The Cold-Temperate West Sichuan Plateau and Tropical Diannan populations were compared to identify genes under adaptive selection in these two habitats. Pathway enrichment analysis showing genes under selection, including the Hippo signaling pathway, GABAergic pathway, and trehalose-phosphate synthase, indicates that most genes under selection pressure are involved in the process of signal transduction and energy metabolism. qRT-PCR analysis reveals that one gene under selection, the AcVIAAT gene, involved in the GABAergic pathway, is responding to cold temperature stress. Through homologous recombination, we show that the AcVIAAT gene is able to replace the CNAG_01904 gene in the fungus Cryptococcus neoformans and that it makes the fungus less sensitive to conditions of oxidative stress and variations in temperature. Our results contribute to our understanding of the evolutionary origin of A. cerana in China and the molecular basis of environmental adaptation.

RESUMO

The studies on the solvent effects of methyltestorone (MT) in 19 different organic solvents and n-C(6)H(14)/CHCl(3) binary solvents were undertaken by FTIR spectroscopy. The wavenumbers of carbonyl stretching vibration for MT (nu(CO)) in individual solvents were correlated with the empirical solvent parameters such as Schleyer's linear free energy equation (G-value), the solvent acceptor number (AN) and the linear solvation energy relationships (LSER), respectively. The solvent-induced carbonyl stretching vibration wavenumber shifts of MT exhibited a better correlation with the LSER than the other solvent parameters. With the increase of the volume fraction of chloroform (X(CHCl3)) in the n-C(6)H(14)/CHCl(3) binary solvents, two kinds of nu(CO) of MT were observed and assigned. The formation constant (K(0)) of the interaction between MT and CHCl(3) and the free energy change (DeltaG(0)) of the system were calculated in the binary solvents by Nash's method.

RESUMO

BACKGROUND: The long noncoding RNA, small nucleolar RNA host gene 8 (SNHG8), is upregulated in multiple human cancer types. However, whether SNHG8 is aberrantly expressed in esophageal squamous cell carcinoma (ESCC) and its biological functions have yet to be elucidated. Thus, we aimed to determine the expression status of SNHG8 in ESCC, explore the effects of SNHG8 on the oncogenicity of ESCC, and investigate the potential underlying mechanisms. METHODS: SNHG8 expression in ESCC tissues and cell lines was determined via reverse-transcription quantitative polymerase chain reaction. The actions of SNHG8 on the malignant characteristics of ESCC were explored using CCK-8 assay, flow-cytometric analysis, Transwell migration and invasion assays, and tumor xenografts in nude mice. RESULTS: SNHG8 expression was significantly higher in ESCC tissues and cell lines. High SNHG8 expression was revealed to closely correlate with primary tumor invasion depth, lymph node metastases, TNM stage, and worse overall survival among patients with ESCC. Functional investigation showed that ablation of SNHG8 notably restricted ESCC cell proliferation, migration, and invasion while inducing apoptosis in vitro and hindered tumor growth in vivo. In the meantime, SNHG8 acted as a molecular sponge of microRNA-411 (miR-411) in ESCC. Furthermore, miR-411 exerted a tumor-suppressive effect on ESCC cells, and karyopherin alpha 2 (KPNA2) turned out to be a direct target gene of miR-411. Restoring KPNA2 expression neutralized the inhibitory effects of miR-411 overexpression on the malignant behaviors of ESCC cells. Moreover, silencing of miR-411 abrogated the influence of SNHG8 downregulation in ESCC cells. CONCLUSION: SNHG8 may play oncogenic roles in the malignancy of ESCC by sponging miR-411 to increase KPNA2 expression. The SNHG8-miR-411-KPNA2 pathway may be a novel target for the treatment of patients with ESCC and offer potential biomarkers for the diagnosis and prognosis of ESCC.

RESUMO

Evaluation of ecosystem services has become a hotspot in terms of research focus, but uncertainties over appropriate methods remain. Evaluation can be based on the unit price of services (services value method) or the unit price of the area (area value method). The former takes meteorological factors into account, while the latter does not. This study uses Kunyu Mountain Nature Reserve as a study site at which to test the effects of climate on the ecosystem services. Measured data and remote sensing imagery processed in a geographic information system were combined to evaluate gas regulation and soil conservation, and the influence of meteorological factors on ecosystem services. Results were used to analyze the appropriateness of the area value method. Our results show that the value of ecosystem services is significantly affected by meteorological factors, especially precipitation. Use of the area value method (which ignores the impacts of meteorological factors) could considerably impede the accuracy of ecosystem services evaluation. Results were also compared with the valuation obtained using the modified equivalent value factor (MEVF) method, which is a modified area value method that considers changes in meteorological conditions. We found that MEVF still underestimates the value of ecosystem services, although it can reflect to some extent the annual variation in meteorological factors. Our findings contribute to increasing the accuracy of evaluation of ecosystem services.
