Splenectomy versus splenic preservation in total gastrectomy for gastric cancer: a systematic review and meta-analysis comparing survival benefits and short-term complications.

BACKGROUND: There is an ongoing debate regarding the comparative merits of splenectomy (SP) and splenic preservation in the surgical management of gastric cancer. This systematic review and meta-analysis aims to shed light on potential differences in survival outcomes and postoperative complications associated with these two procedures. METHOD: An exhaustive literature search was conducted across multiple databases, namely PubMed, Embase, Cochrane Library, and Web of Science. We utilized a random-effects model via RevMan 5.4 software to conduct a meta-analysis of the hazard ratios (HRs) and risk ratios (RRs) associated with SP and spleen preservation. Subgroup analyses were based on various attributes of the included studies. We employed funnel plots to assess publication bias, and sensitivity analysis was conducted to gauge the stability of the combined results. Both funnel plots and sensitivity analysis were performed using Stata 12. RESULT: Our research incorporated 23 observational studies and three randomized controlled trials, involving a total of 6,255 patients. SP did not yield superior survival outcomes in comparison to splenic preservation, a conclusion that aligns with the combined results of the randomized controlled trials. No statistically significant difference in survival prognosis was observed between SP and splenic preservation, irrespective of whether the patients had proximal gastric cancer or proximal gastric cancer invading the stomach's greater curvature. SP exhibited a higher incidence of all postoperative complications, notably pancreatic fistula and intraabdominal abscesses. However, it did not significantly differ from splenic preservation in terms of anastomotic leakage, incision infection, intestinal obstruction, intra-abdominal bleeding, and pulmonary infection. No significant difference in postoperative mortality between SP and splenic preservation was found. Funnel plots suggested no notable publication bias, and sensitivity analysis affirmed the stability of the combined outcomes. CONCLUSION: Despite the lack of significant differences in certain individual complications and postoperative mortality, the broader pattern of our data suggests that SP is associated with a greater overall frequency of postoperative complications, without providing additional survival benefits compared to splenic preservation. Thus, the routine implementation of SP is not advocated.

When doctors perform surgery for gastric (stomach) cancer, they sometimes remove the spleen, a procedure known as splenectomy (SP). However, there's a debate on whether removing the spleen is better than preserving it. Our study aimed to compare these two methods in terms of patient survival and the risk of complications after surgery. To do this, we looked at data from 26 studies involving 6,255 patients. Our analysis was thorough, using advanced statistical methods to ensure accuracy. Here's what we found: patients who had their spleen removed did not live longer than those who kept their spleen. Whether the cancer was just in the upper part of the stomach or had spread to the nearby large curve of the stomach, the survival rates were similar for both groups. Patients who underwent SP faced more postoperative complications, especially issues like pancreatic fistula and intra-abdominal abscesses. However, for some complications like leakage from the surgical joint, infection of the wound, bowel obstruction, internal bleeding, and lung infections, there was no significant difference between the two groups. The chances of dying post-surgery were similar whether patients had their spleen removed or not. Our findings suggest that routinely removing the spleen during gastric cancer surgery does not improve survival rates and is linked to more postoperative complications. Therefore, it may be better to avoid removing the spleen unless absolutely necessary.

A simulation training of family management for parents of children with epilepsy: a randomized clinical trial.

BACKGROUND: Epilepsy is a chronic neurological disorder that is more likely to be diagnosed in children. The main treatment involves long-term use of anti-epileptic drugs and above all, home care is of great importance. As there has not been a widely accepted home care protocols, simulating a home care environment is necessary for caregivers to develop skills of proper home care. This study aims to evaluate the effectiveness of a simulation training of family management style (STOFMS) for parents of children with epilepsy in China. METHODS: A randomized controlled trial was conducted on 463 children with epilepsy and their families. They were recruited from March 2020 to November 2022 and randomly assigned to the STOFMS group or the conventional group in a 1:1 ratio. Scores of family management measures, 8-item of Morisky Medication Adherence and epilepsy clinical symptom of both groups were collected at three points of time: within 24 h after admission (T0), 3 months after discharge (T1), and 6 months after discharge (T2). Changes due to intervention were compared across groups by repeated-measures ANOVA. The study report followed the CONSORT 2010 checklist. RESULTS: There were statistically significant differences between the two groups at T2. A considerable increase over the baseline was observed in the total management level score and subscale scores in the STOFMS group at T1, compared with essentially no change in the control group. In terms of medication adherence, the STOFMS group performance improved greatly at T1 and T2 compared with the control group. The same result was also found in clinical efficacy at T2 (p < 0.05). CONCLUSION: STOFMS is an effective intervention to improve family management level, treatment adherence and clinical efficacy for children with epilepsy.

Combining systemic inflammatory response index and albumin fibrinogen ratio to predict early serious complications and prognosis after resectable gastric cancer.

BACKGROUND: Gastric cancer has a high incidence and fatality rate, and surgery is the preferred course of treatment. Nonetheless, patient survival rates are still low, and the incidence of major postoperative complications cannot be disregarded. The systemic inflammatory response, nutritional level, and coagulation status are key factors affecting the postoperative recovery and prognosis of gastric cancer patients. The systemic inflammatory response index (SIRI) and the albumin fibrinogen ratio (AFR) are two valuable comprehensive indicators of the severity and prognosis of systemic inflammation in various medical conditions. AIM: To assess the clinical importance and prognostic significance of the SIRI scores and the AFR on early postoperative outcomes in patients undergoing radical gastric cancer surgery. METHODS: We conducted a retrospective analysis of the clinicopathological characteristics and relevant laboratory indices of 568 gastric cancer patients from January 2018 to December 2019. We calculated and compared two indicators of inflammation and then examined the diagnostic ability of combined SIRI and AFR values for serious early postoperative complications. We scored the patients and categorized them into three groups based on their SIRI and AFR levels. COX analysis was used to compare the three groups of patients the prognostic value of various preoperative SIRI-AFR scores for 5-year overall survival (OS) and disease-free survival (DFS). RESULTS: SIRI-AFR scores were an independent risk factor for prognosis [OS: P = 0.004; hazards ratio (HR) = 3.134; DFS: P < 0.001; HR = 3.543] and had the highest diagnostic power (area under the curve: 0.779; 95% confidence interval: 0.737-0.820) for early serious complications in patients with gastric cancer. The tumor-node-metastasis stage (P = 0.001), perioperative transfusion (P = 0.044), positive carcinoembryonic antigen (P = 0.014) findings, and major postoperative complications (P = 0.011) were factors associated with prognosis. CONCLUSION: Preoperative SIRI and AFR values were significantly associated with early postoperative survival and the occurrence of severe complications in gastric cancer patients.

Water and Air Stable Copper(I) Complexes of Tetracationic Catenane Ligands for Oxidative C-C Cross-Coupling.

Aqueous soluble and stable Cu(I) molecular catalysts featuring a catenane ligand composed of two dicationic, mutually repelling but mechanically interlocked macrocycles are reported. The ligand interlocking not only fine-tunes the coordination sphere and kinetically stabilizes the Cu(I) against air oxidation and disproportionation, but also buries the hydrophobic portions of the ligands and prevents their dissociation which are necessary for their good water solubility and a sustained activity. These catenane Cu(I) complexes can catalyze the oxidative C-C coupling of indoles and tetrahydroisoquinolines in water, using H2O2 as a green oxidant with a good substrate scope. The successful use of catenane ligands in exploiting aqueous Cu(I) catalysis thus highlights the many unexplored potential of mechanical bond as a design element for exploring transition metal catalysis under challenging conditions.

Treatment and prevention of pigeon diarrhea through the application of Lactobacillus SNK-6.

In the pigeon industry, treating and preventing diarrhea is vital because it is a serious health problem for pigeons. This study investigated the incidence of diarrhea in 3 pigeon farms in Shanghai, and analyzed the microflora through 16S rDNA high-throughput sequencing. Four strains of Escherichia coli (E. coli) isolated from pigeon diarrhea feces were administered via gavage to healthy pigeons, with each pigeon receiving 2 × 108 CFU. Pigeons that developed diarrhea after E. coli challenge were treated with 3 g of Lactobacillus salivarius SNK-6 (L. salivarius SNK-6) health sand (1.6 × 107 CFU/g). Then, a mass feeding experiment expanded to 688 pairs of pigeons with 3 replicates, each receiving 3 g of health sand containing L. salivarius SNK-6 (1.6 × 107 CFU/g) every 2 wk, and fecal status monitored and recorded. The study found that the relative abundance of the Lactobacillus genus and L. salivarius in feces from pigeons with diarrhea was significantly lower than in normal pigeon feces (P < 0.05). In contrast, E. coli showed a higher abundance and diversity in feces from pigeons with diarrhea than in normal feces (P < 0.05). Three out of the 4 isolated E. coli strains caused pigeon diarrhea, resulting in a significant reduction in microbial diversity in fecal samples (P < 0.05). Both the small group attack experiment and the mass-fed additive experiment in pigeon farms demonstrated that feeding L. salivarius SNK-6 effectively cured and prevented diarrhea. Pigeons fed with L. salivarius SNK-6 exhibited no diarrhea, while the control group had a 10% diarrhea rate. In summary, a deficiency of Lactobacillus or a high abundance of E. coli in the intestine could easily cause pigeon diarrhea. Feeding L. salivarius SNK-6 could treat pigeon diarrhea, and continuous supplementation could maintain stable preventive effects.

Isolation and Proteomic Analysis of Extracellular Vesicles from Lactobacillus salivarius SNK-6.

The proteins carried by the extracellular vesicles of Lactobacillus salivarius SNK-6 (LsEVs) were identified to provide a foundation for further explorations of the probiotic activities of L. salivarius SNK-6. LsEVs were isolated from the culture media of L. salivarius SNK-6 and morphological analysis was conducted by scanning electron microscopy. Subsequent transmission electron microscopy and nanoparticle tracking analysis were performed to assess the morphology and particle size of the LsEVs. In addition, the protein composition of LsEVs was analyzed using silver staining and protein mass spectrometry. Finally, internalization of the identified LsEVs was confirmed using a confocal microscope, and enzyme-linked immunosorbent assay was employed to analyze the levels of inflammatory cytokines in LPS-challenged RAW264.7 cells. The results revealed that the membrane-enclosed LsEVs were spherical, with diameters ranging from 100-250 nm. The LsEVs with diameters of 111-256 nm contained the greatest amount of cargo. In total, 320 proteins (10-38 kD) were identified in the LsEVs and included anti-inflammatory molecules, such as PrtP proteinase, co-chaperones, and elongation factor Tu, as well as some proteins involved in glycolysis/gluconeogenesis, such as fructose-1,6-bisphosphate aldolase. Enrichment analysis showed these proteins to be related to the terms "metabolic pathway," "ribosome," "glycolysis/gluconeogenesis," "carbohydrate metabolism," and "amino acid metabolism." Furthermore, the LsEVs were internalized by host liver cells and can regulate inflammation. These findings confirm that LsEVs contain various functional proteins that play important roles in energy metabolism, signal transduction, and biosynthesis.

Perioperative change trajectories and predictors of swallowing function and swallowing-related quality of life in patients with oral cancer: a longitudinal observational study.

OBJECTIVE: To determine change trajectories and predictors of swallowing function and swallowing-related quality of life (QoL) in perioperative patients with oral cancer. DESIGN: Longitudinal observational study. SETTING: A tertiary cancer hospital in Hunan Province, China. PARTICIPANTS: Patients with oral cancer scheduled for surgery were recruited using convenience sampling. PRIMARY AND SECONDARY OUTCOME MEASURES: The primary outcomes were swallowing function and swallowing-related QoL. The secondary outcomes were the predictors of the swallowing function and swallowing-related QoL. METHODS: The participants completed the sociodemographic and clinical data questionnaire, Nutritional Risk Screening 2002 and MD Anderson Dysphagia Inventory before surgery, 7 days after operation and 1 month after operation. Data were analysed using t-test, analysis of variance and generalised linear models. RESULTS: Among 138 participants who completed all the three surveys, 41 (29.71%) had moderate to severe dysphagia before surgery. Swallowing function and swallowing-related QoL changed over time, showing the trend of decline first and then increase. Preoperative swallowing function and swallowing-related QoL were affected by sex, lymphocyte level, preoperative nutritional risk and primary tumour site. At 7 days postoperatively, tracheotomy affected swallowing function. At 1 month postoperatively, age and marital status influenced swallowing function, whereas age, type of job and preoperative nutritional risk influenced swallowing-related QoL. CONCLUSIONS: Our study demonstrates that perioperative patients with oral cancer generally faced swallowing disorders, especially in the acute phase after surgery. Healthcare providers should pay attention to the swallowing function of perioperative patients with oral cancer, especially those with preoperative nutritional risk, tongue tumour, tracheotomy, age <60 years, and no spouse and the employed patients, and provide available interventions, such as swallowing and nutritional therapy, as early as possible to improve their swallowing function. Meanwhile, doctors should recommend the most evidence-based treatment options, such as reconstruction or not, preoperative chemotherapy or not, to patients.

Influencing factors of knowledge, attitude and behavior in children's palliative care among pediatric healthcare workers: a cross-sectional survey in China.

BACKGROUND: Palliative care has become a key medical field worldwide. Although research relating to adult palliative care is well-established, less is known about children's palliative care (CPC). Therefore, this study investigated the knowledge, attitude and behavior of pediatric healthcare workers (PHWs) regarding CPC and analyzed the influencing factors for the implementation and development of CPC. METHODS: A cross-sectional survey of 407 PHWs was carried out in a Chinese province from November 2021 to April 2022. The questionnaire consisted of two parts: a general information form and questions on the knowledge, attitude and behavior of PHWs about CPC. Data were analyzed using t-test, ANOVA and multiple regression analysis. RESULTS: The total score of the PHWs' knowledge, attitude and behavior about CPC was 69.98, which was at a moderate level. PHWs' CPC knowledge, attitude, and behavior are positively correlated.The most important influencing factors were working years, highest education, professional title, job position, marital status, religion, grade of hospital (I, II or III), type of medical institution, experience of caring for a terminally ill child/kinsfolk and total hours of CPC education and training received. CONCLUSIONS: In this study, PHWs in a Chinese province had the lowest scores on the knowledge dimension of CPC, with moderate attitude and behavior and various influencing factors. In addition to professional title, highest education and working years, it is also worth noting that the type of medical institution and marital status also affected the score. Continuing education and training of PHWs in CPC should be emphasized by the administrators of relevant colleges and medical institutions. Future research should start with the above-mentioned influencing factors and focus on setting up targeted training courses and evaluating the post-training effects.

Analysis of Starch Structure and Pasting Characteristics of Millet Thick Wine during Fermentation.

Starch is the main substrate in millet thick wine (MTW). In order to control the fermentation process of MTW, it is critical to monitor changes in the starch structure and physicochemical characteristics during the fermentation of MTW. In the present study, the structural characteristics of MTW starch were analyzed by scanning electron microscopy (SEM), confocal laser scanning microscopy (CLSM), X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR) and rapid viscosity analysis (RVA). The results of SEM and CLSM showed that large starch granules in MTW swelled, developed cavities, and ruptured or even vanished with the prolongation of the fermentation time, whereas the size and shape of small starch granules barely changed, only falling off the pomegranate-seed-like aggregates. With the increase in fermentation time, the relative crystallinity of starch in MTW gradually increased. In addition, the short-range ordered structures underwent complex changes. Changes in the starch morphology and ordered structure led to an increase in the peak viscosity time and the initial gelatinization temperature. The present results reveal the beneficial effect of fermentation on MTW processing and suggest its potential applications in other millet-based fermented products.

ctDNA as a prognostic biomarker in resectable CLM: Systematic review and meta-analysis.

Cell-free circulating tumor DNA (ctDNA) is synthesized by tumor cells, including metastatic tumors, and circulates in the bloodstream. Evidence suggests that ctDNA is a potential predictive and prognostic biomarker for colorectal cancer (CRC), but its predictive efficacy in detecting CRC liver metastasis (CLM) remains unclear. Additionally, its utility in the clinical setting needs further investigation. We conducted a meta-analysis to determine the utility of ctDNA as a biomarker for predicting the prognosis of CLM and investigate the relationship between CLM and ctDNA positivity. A literature search was performed in electronic databases to identify relevant studies published up to March 19, 2022. We retrieved data on overall survival (OS), disease-free survival (DFS), and recurrence-free survival (RFS) for both ctDNA-positive and ctDNA-negative colorectal liver metastasis (CLM) patients from the selected articles. Hazard ratios (HRs) were also calculated for these survival outcomes analysis was also performed. The stability of the combined meta-analysis was verified by sensitivity analysis and publication bias evaluation. Ten trials were included, and 615 patients were evaluated. In patients with CLM, pooled HRs revealed a substantial link between ctDNA positivity and RFS/DFS. Subgroup analysis revealed that ctDNA had a prospective detection value. Sensitivity analysis and publication bias evaluation indicated stable results. Although the results on pooled HR for OS suggested that ctDNA-positive patients had a shorter survival time, their pooled HRs had a relatively evident heterogeneity, and sensitivity analysis and publication bias evaluation indicated that pooled HRs were extremely unstable. In conclusion, our results demonstrate that ctDNA appears to be a prognostic biomarker for resectable CLM patients.

Tests on a scale for measuring the core competencies of paediatric specialist nurses: An exploratory quantitative study.

AIM: This study aimed to develop a tool to measure paediatric specialist nurses' core competencies and examine the scale's validity and reliability. DESIGN: An exploratory quantitative study. METHODS: This study was performed in April 2022 with 302 paediatric specialist nurses in mainland China. Items were created through a literature review, a qualitative interview, and the Delphi method. The data were evaluated using descriptive statistics, independent sample t-test, explanatory factor analysis, Pearson correlation coefficient, Cronbach's alpha coefficient and split-half reliability. RESULTS: The final scale consisted of five factors and 32 items. The factors were communication, coordination and judgement abilities; professional technology mastery ability; specialist knowledge mastery ability; medical-related processes; and evidence-based nursing competencies. The explained total variance of the five factors was 62.216%. The scale-level and item-level CVI of this scale was 1.00, and the mean CVR of the total scale was 0.788. The Pearson correlation coefficients of each dimension and the total dimension of the scale was 0.709-0.892, and within each dimension, it was 0.435-0.651. The Cronbach's α of this scale was 0.944, and its split-half reliability was 0.883.

A 21-bp InDel in the promoter of STP1 selected during tomato improvement accounts for soluble solid content in fruits.

Domestication and improvement are important processes that generate the variation in genome and phonotypes underlying crop improvement. Unfortunately, during selection for certain attributes, other valuable traits may be inadvertently discarded. One example is the decline in fruit soluble solids content (SSC) during tomato breeding. Several genetic loci for SSC have been identified, but few reports on the underlying mechanisms are available. In this study we performed a genome-wide association study (GWAS) for SSC of the red-ripe fruits in a population consisting of 481 tomato accessions with large natural variations and found a new quantitative trait locus, STP1, encoding a sugar transporter protein. The causal variation of STP1, a 21-bp InDel located in the promoter region 1124 bp upstream of the start codon, alters its expression. STP1 Insertion accessions with an 21-bp insertion have higher SSC than STP1 Deletion accessions with the 21-bp deletion. Knockout of STP1 in TS-23 with high SSC using CRISPR/Cas9 greatly decreased SSC in fruits. In vivo and in vitro assays demonstrated that ZAT10-LIKE, a zinc finger protein transcription factor (ZFP TF), can specifically bind to the promoter of STP1 Insertion to enhance STP1 expression, but not to the promoter of STP1 Deletion , leading to lower fruit SSC in modern tomatoes. Diversity analysis revealed that STP1 was selected during tomato improvement. Taking these results together, we identified a naturally occurring causal variation underlying SSC in tomato, and a new role for ZFP TFs in regulating sugar transporters. The findings enrich our understanding of tomato evolution and domestication, and provide a genetic basis for genome design for improving fruit taste.

Peripheral intravenous infusion for children based on computer digital video technology.

PURPOSE: Intravenous infusion techniques often take a long time and require continuous monitoring of the infusion, and the needle must be removed promptly at the end of the injection, placing a burden on the patient, family and medical workers. Thus, this paper presents a droplet flow rate monitoring system based on an embedded system. METHODS: In our retrospective study, according to different intervention measures, 80 patients were divided into two groups to compare the improvement of children's adverse psychological conditions. The patients were divided into control and intervention groups, with 40 patients in each group. Patients in the intervention group received psychological care and Online Real-Time Fusion Method to monitor the infusion state. Patients in the control group received routine infusions. Computer digital video technology and online real-time fusion algorithm were utilized to determine whether the parameters of the intravenous infusion model were optimized. The model's accuracy was used to evaluate whether the success rate of one-time needle insertion was improved. RESULTS: The system can also be used for other monitoring. It is simple and convenient to set up and dismantle. The system can significantly relieve medical workers and patients. It was found that the observation group is significantly better than the control group in terms of psychological improvement (P<0.05). Comparing the patient's satisfaction, the difference between the two groups was statistically significant. CONCLUSION: When administering intravenous infusions in children, applying various forms of psychological interventions and giving emotional support can significantly improve their compliance and their mental state. It is of great significance to enhance the effect of infusions in patients.

Mechanism and regulation of mitophagy in nonalcoholic fatty liver disease (NAFLD): A mini-review.

Mitochondrial dysfunction has been hypothesized to play a central role in the pathobiology of nonalcoholic fatty liver disease (NAFLD). Thus, maintenance of mitochondria homeostasis and function is important for NAFLD treatment. Mitophagy, a process that selectively clears damaged or dysfunctional mitochondria through autophagic machinery, is beneficial for mitochondrial homeostasis. Notably, strategies that regulate mitophagy exert beneficial effects in preclinical experiments. Traditional Chinese medicine (TCM) is a natural product including active ingredients, extracts, and has great potential in the prevention and treatment of liver diseases. Given the importance of mitophagy, this review summarizes mitophagy-related pathways and the latest findings on the regulation of mitophagy in NAFLD. We also highlight the potential of TCM targeting mitophagy for the treatment of NAFLD.

Lactobacillus salivarius SNK-6 Regulates Liver Lipid Metabolism Partly via the miR-130a-5p/MBOAT2 Pathway in a NAFLD Model of Laying Hens.

Lactobacillus spp., as probiotics, have shown efficacy in alleviating nonalcoholic fatty liver disease (NAFLD). Here, we screened a new probiotic strain, Lactobacillus salivarius SNK-6 (L. salivarius SNK-6), which was isolated from the ileum of healthy Xinyang black-feather laying hens in China. We investigated the beneficial activity of L. salivarius SNK-6 in a NAFLD model in laying hens and found that L. salivarius SNK-6 inhibited liver fat deposition and decreased serum triglyceride levels and activity of aspartate transaminase and alanine transaminase. MBOAT2 (membrane-bound O-acyltransferase domain containing 2) was directly targeted by miR-130a-5p, which was downregulated in the liver of NAFLD laying hens but reversed after L. salivarius SNK-6 treatment. Downregulation of MBOAT2, L. salivarius SNK-6 supplementation in vivo, and L. salivarius SNK-6 cell culture treatment in vitro suppressed the mRNA expression of genes involved in the PPAR/SREBP pathway. In addition, 250 metabolites were identified in the supernatants of L. salivarius SNK-6 culture media, and most of them participated in metabolic pathways, including amino acid, carbohydrate, and lipid metabolism. Targeted metabolomic analysis revealed that acetate, butyrate, and propionate were the most abundant short-chain fatty acids, while cholic acid, ursodeoxycholic acid, chenodeoxycholic acid, and tauroursodeoxycholic acid were the four most-enriched bile acids among L. salivarius SNK-6 metabolites. This may have contributed to the reparative effect of L. salivarius SNK-6 in the NAFLD chicken model. Our study suggested that L. salivarius SNK-6 alleviated liver damage partly via the miR-130a-5p/MBOAT2 signaling pathway.

Phosphogluconate dehydrogenase is a predictive biomarker for immunotherapy in hepatocellular carcinoma.

Background: Phosphogluconate dehydrogenase (PGD) is involved in the regulation of various tumors. However, its role in hepatocellular carcinoma (HCC) is poorly understood. This study tried to determine the prognostic efficacy of PGD and its value for immunotherapy in HCC. Methods: The data from the TCGA database was used to explore the predictive power of PGD expression and methylation on the overall survival (OS) of HCC through Cox regression and the Kaplan-Meier analysis. Then, we used the GEO and ICGC database to further verify the predictive power. Finally, the relationship between PGD and immune cells and the relationship between PGD and the efficacy of immunotherapy were explored through bioinformatics analysis in HCC. Results: PGD is highly expressed in HCC tissues, which is negatively regulated by PGD methylation. Low PGD expression and PGD hypermethylation predict better OS in HCC patients. Besides, a meta-analysis based on the TCGA, GSE14520, and ICGC databases further confirms that low PGD expression is closely related to favorable OS. Then, we find significant differences of immune cell infiltrations between high and low PGD expression groups. Expressions of immune checkpoints, most HLA members and tumor mutation burden (TMB) are higher in the high PGD expression group, which indicates beneficial efficacy of immunotherapy in this group. And the potential mechanisms of PGD are exhibited. Conclusion: PGD is an independent prognostic factor of HCC patients and plays an important role in immune cell infiltration and immunotherapy, which indicates that PGD can be used as a predictive biomarker for HCC immunotherapy.

Supplementation with honeysuckle extract improves growth performance, immune performance, gut morphology, and cecal microbes in geese.

The study aimed to investigate the effects of honeysuckle extract (HE) on growth performance, serum biochemical indexes, immune organ indexes, gut morphology, and gut microbes in geese. A total of 180 28-day-old Holdobaki geese were randomly divided into three groups. Each group contained 6 replicates (10 geese, with 5 males and 5 females). The BD group was fed the basal diet, the HE1 group was fed the basal diet supplemented with 1 g/kg of HE, and the HE2 group was fed the basal diet supplemented with 2 g/kg of HE. The experiment lasted for 42 days. The results showed that, compared with the BD group, the average daily gain (ADG) of the HE1 and HE2 groups tended to increase (0.05 < P < 0.10), but the average daily feed intake (ADFI) and final body weight (BW) did not differ significantly, and the feed/gain ratio (F/G) was significantly lower (P < 0.01). The bursa index and the thymus index tended to increase (0.05 < P < 0.10), and serum immunoglobulin A (IgA) and immunoglobulin G (IgG) levels increased significantly (P < 0.05). In the HE1 and HE2 groups, the crypt depth (CD) in the jejunum tended to decrease (0.05 < P < 0.10), and the villus height/crypt depth ratio (V/C) increased significantly in the jejunum and the ileum (P < 0.05). According to 16sRNA microbial community diversity analysis, Firmicutes, Bacteroidetes, Proteobacteria, and Actinobacteria were the dominant phyla. The abundance of Firmicutes was significantly decreased (P < 0.01), while that of Bacteroidetes was significantly increased (P < 0.01), in the HE1 and HE2 groups compared with the BD group. Bacteroides barnesiae, Subdoligranulum variabile, Bacteroides plebeius, and Faecalibacterium prausnitzii were the dominant species, and the abundance of B. plebeius and F. prausnitzii was significantly increased (P < 0.05). According to the LEfSe analysis, BD enriched g_Dorea and g_Dehalobacterium; HE1 enriched g_Faecalibacterium, g_Dialister, g_Prevotella, g_Megamonas, g_Phascolarctobacterium, g_Paraprevotella, g_Anaerostipes, g_Staphylococcus, g_Odoribacter, g_Succinivibrio, and g_Sutterella; and HE2 enriched g_Parabacteroides, g_Olsenella, g_human, and g_Rikenella. According to the Spearman correlation analysis, Bacteroides plebeius was positively correlated with final BW, ADG, IgA, IgG, VH (ileum), and V/C (ileum) and was negatively correlated with F/G and CD (ileum); Ruminococcus gnavus was negatively correlated with final BW, ADG, IgA, and IgG. HE supplementation at 1 g/kg improved growth performance, immune performance, gut morphology, and cecal microbes.

chi-miR-99b-3p Regulates the Proliferation of Goat Skeletal Muscle Satellite Cells In Vitro by Targeting Caspase-3 and NCOR1.

We previously found that chi-miR-99b-3p was highly expressed in the skeletal muscle of 7-month-old (rapid growth period) goats and speculated that it may be associated with muscle development. To further investigate the role of chi-miR-99b-3p in goats, we found that chi-miR-99b-3p acted as a myogenic miRNA in the regulation of skeletal muscle development. Dual-luciferase reporter assays, qRT-PCR, and Western blot results confirmed that Caspase-3 and nuclear receptor corepressor 1 were direct targets for chi-miR-99b-3p as their expression was inhibited by this miR. Cell proliferation and qRT-PCR assays showed that chi-miR-99b-3p promoted proliferation through relevant targets and intrinsic apoptosis-related genes in goat skeletal muscle satellite cells (SMSCs), whereas inhibition of chi-miR-99b-3p had the opposite effect. Furthermore, integrative transcriptomic analysis revealed that overexpression of chi-miR-99b-3p induced various differentially expressed (DE) genes mainly associated with the cell cycle, relaxin signaling pathway, DNA replication, and protein digestion and absorption. Notably, most of the cell-cycle-related genes were downregulated in SMSCs after miR-99b-3p upregulation, including the pro-apoptosis-related gene BCL2. In addition, 47 DE miRNAs (16 upregulated and 31 downregulated) were determined by Small RNA-sequencing in SMSCs after chi-miR-99b-3p overexpression. Based on the KEGG enrichment analysis, we found that these DE miRNAs were involved in the biological pathways associated with the DE genes. Our study demonstrated that chi-miR-99b-3p was an effective facilitator of goat SMSCs and provided new insights into the mechanisms by which miRNAs regulate skeletal muscle growth in goats.

LncRNA DUXAP8 as a prognostic biomarker for various cancers: A meta-analysis and bioinformatics analysis.

Background: Dual homeoboxes A pseudogene 8 (DUXAP8) is a newly discovered long noncoding RNA that has been shown to function as an oncogene in a variety of human malignant cancers. By integrating available data, this meta-analysis sought to determine the relationship between clinical prognosis and DUXAP8 expression levels in diverse malignancies. Materials and methods: A systematic search was performed to identify eligible studies from several electronic databases from their inception to 25 October 2021. Pooled odds ratios and hazard ratios with 95% CI were used to estimate the association between DUXAP8 expression and survival. For survival analysis, the Kaplan-Meier method and COX analysis were used. Furthermore, we utilized Spearman's correlation analysis to explore the correlation between DUXAP8 and tumor mutational burden (TMB), microsatellite instability (MSI), the related genes of mismatch repair (MMR), DNA methyltransferases (DNMTs), and immune checkpoint biomarkers. Results: Our findings indicated that overexpression of DUXAP8 was related to poor overall survival (OS) (HR = 1.63, 95% CI, 1.49-1.77, p < 0.001). In addition, elevated DUXAP8 expression was closely related to poor OS in several cancers in the TCGA database. Moreover, DUXAP8 expression has been associated with TMB, MSI, and MMR in a variety of malignancies. Conclusion: This study revealed that DUXAP8 might serve as a prognostic biomarker and potential therapeutic target for cancer.

Testing a Family Supportive End of Life Care Intervention in a Chinese Neonatal Intensive Care Unit: A Quasi-experimental Study With a Non-randomized Controlled Trial Design.

Background: Neonatal death often occurs in tertiary Neonatal Intensive Care Units (NICUs). In China, end-of-life-care (EOLC) does not always involve parents. Aim: The aim of this study is to evaluate a parent support intervention to integrate parents at the end of life of their infant in the NICU. Methods: A quasi-experimental study using a non-randomized clinical trial design was conducted between May 2020 and September 2021. Participants were infants in an EOLC pathway in the NICU and their parents. Parents were allocated into a family supportive EOLC intervention group or a standard EOLC group based on their wishes. The primary outcomes depression (Edinburgh Postnatal Depression Scale for mothers; Hamilton Depression rating scale for fathers) and Satisfaction with Care were measured 1 week after infants' death. Student t-test for continuous variables and the Chi-square test categorical variables were used in the statistical analysis. Results: In the study period, 62 infants died and 45 infants and 90 parents were enrolled; intervention group 20 infants, standard EOLC group 25 infants. The most common causes of death in both groups were congenital abnormalities (n = 20, 44%). Mean gestational age of infants between the family supportive EOLC group and standard EOLC group was 31.45 vs. 33.8 weeks (p = 0.234). Parents between both groups did not differ in terms of age, delivery of infant, and economic status. In the family support group, higher education levels were observed among mother (p = 0.026) and fathers (p = 0.020). Both mothers and fathers in the family supportive EOLC group had less depression compared to the standard EOLC groups; mothers (mean 6.90 vs. 7.56; p = 0.017) and fathers (mean 20.7 vs. 23.1; p < 0.001). Parents reported higher satisfaction in the family supportive EOLC group (mean 88.9 vs. 86.6; p < 0.001). Conclusions: Supporting parents in EOLC in Chinese NICUs might decreased their depression and increase satisfaction after the death of their infant. Future research needs to focus on long-term effects and expand on larger populations with different cultural backgrounds. Clinical Trial Registration: www.ClinicalTrials.gov, identifier: NCT05270915.
