Abstract Objective To explore the feasibility of injectable platelet-rich fibrin (i-PRF) in regenerative endodontics by comparing the effect of i-PRF and platelet-rich fibrin (PRF) on the biological behavior and angiogenesis of human stem cells from the apical papilla (SCAPs). Methodology i-PRF and PRF were obtained from venous blood by two different centrifugation methods, followed by hematoxylin-eosin (HE) staining and scanning electron microscopy (SEM). Enzyme-linked immunosorbent assay (ELISA) was conducted to quantify the growth factors. SCAPs were cultured with different concentrations of i-PRF extract (i-PRFe) and PRF extract (PRFe), and the optimal concentrations were selected using the Cell Counting Kit-8 (CCK-8) assay. The cell proliferation and migration potentials of SCAPs were then observed using the CCK-8 and Transwell assays. Mineralization ability was detected by alizarin red staining (ARS), and angiogenesis ability was detected by tube formation assay. Real-time quantitative polymerase chain reaction (RT-qPCR) was performed to evaluate the expression of genes related to mineralization and angiogenesis. The data were subjected to statistical analysis. Results i-PRF and PRF showed a similar three-dimensional fibrin structure, while i-PRF released a higher concentration of growth factors than PRF ( P <.05). 1/4× i-PRFe and 1/4× PRFe were selected as the optimal concentrations. The cell proliferation rate of the i-PRFe group was higher than that of the PRFe group ( P <.05), while no statistical difference was observed between them in terms of cell mitigation ( P >.05). More importantly, our results showed that i-PRFe had a stronger effect on SCAPs than PRFe in facilitating mineralization and angiogenesis, with the consistent result of RT-qPCR ( P <.05). Conclusion This study revealed that i-PRF released a higher concentration of growth factors and was superior to PRF in promoting proliferation, mineralization and angiogenesis of SCAPs, which indicates that i-PRF could be a promising biological scaffold for application in pulp regeneration. plateletrich platelet rich iPRF i (i-PRF (PRF SCAPs. .

ABSTRACT Introduction: This study aimed to investigate the predictive value of the vasoactive-inotropic score (VIS) at different time points for postoperative prolonged mechanical ventilation (PMV) in adult congenital heart disease patients undergoing surgical treatment combined with coronary artery bypass grafting. Methods: Patients were divided into two groups that developed PMV or not. The propensity score matching method was applied to reduce the effects of confounding factors between the two groups. VIS at different time points (VIS at the end of surgery, VIS6h, VIS12h, and VIS12h max) after surgery were recorded and calculated. The value of VIS in predicting PMV was analyzed by the receiver operating characteristic (ROC) curve, and multivariate logistic regression was used to analyze independent risk factors. Results: Among 250 patients, 52 were in the PMV group, and 198 were in the non-PMV group. PMV rate was 20.8%. After propensity score matching, 94 patients were matched in pairs. At each time point, the area under the ROC curve predicted by VIS for PMV was > 0.500, among which VIS at the end of surgery was the largest (0.805). The optimal cutoff point for VIS of 6.5 could predict PMV with 78.7% sensitivity and 72.3% specificity. VIS at the end of surgery was an independent risk factor for PMV (odds ratio=1.301, 95% confidence interval 1.091~1.551, P<0.01). Conclusion: VIS at the end of surgery is an independent predictor for PMV in patients with adult congenital heart disease surgical treatment combined with coronary artery bypass grafting.

Natural killer (NK) cells are a critical component of the innate immune system and one of the immune cells most sensitive to exercise. So far, it is widely believed that moderate exercise can significantly enhance the proliferation and activity of NK cells, strengthening immune function. However, the impact of exercise on NK cells is a dynamic and complex process. In addition to the type of exercise, the frequency, intensity, and duration of exercise are also key factors. This article not only briefly summarizes the activation mechanisms of NK cells but also delves into the potential importance of exercise as a non-pharmacological strategy in modulating NK cell activity and enhancing the immune system. Emerging studies have indicated that the timing and regularity of exercise bouts might also influence NK cell responses. Moreover, the interaction between exercise and other components of the immune system, such as cytokines and chemokines, could further modulate the functionality of NK cells. The above research is of crucial significance for achieving a deeper understanding of the intricate connection between exercise and NK cell function, as well as the development of effective health promotion strategies. In addition, further research is needed to investigate the effects of long-term exercise on NK cell function and the interaction between exercise and NK cell-mediated immune responses. Translating these research findings into precisely tailored exercise programs for specific populations, taking into account factors like age, health status, and genetic predisposition, could potentially offer unprecedented prospects for further advancements in this burgeoning field of study.

Abstract Background Significant association between bullous pemphigoid (BP) and stroke has been reported. This study aimed to evaluate the level of anti-BP180 antibody in stroke patients to explore the relationship between BP and stroke in their pathogenesis. Methods We collected serum samples from stroke patients and matched controls between February 2019 and June 2020. The anti-BP180 antibody levels were measured by enzyme-linked immunosorbent assay (ELISA). Results A total of 1183 stroke patients including 970 with cerebral infarction (CI), 192 with intracerebral hemorrhage (ICH), 21 with CI and ICH, and 855 controls were enrolled in this study. Anti-BP180 autoantibody values were significantly higher in stroke patients than in controls (p < 0.001). Anti-BP180 autoantibody-positive rates were 12.51% (148) in stroke patients and 4.68% (40) in controls (p < 0.001, OR = 2.65). In anti-BP180 autoantibody-positive subjects, the values were significantly higher in stroke patients than in controls (p < 0.001). However, only 10 (6.76%) stroke patients and 3 (7.5%) controls had high values (> 100 RU/mL) (p = 0.87). Stratified analysis showed that anti-BP180 antibody positive rates were independent of age, sex, and stroke subtypes in the stroke group. Positive rates in patients with both CI and ICH were nearly two times higher than those in patients with either CI or ICH alone (p = 0.11, OR = 1.94). Study limitations This study had a limited sample size and lacked quantitative criteria for stroke severity. Conclusions Anti-BP180 antibody values and positive rates were higher in stroke patients than in controls, suggesting that stroke patients may have higher of developing BP.

ABSTRACT Objective: MCM3AP-AS1 has been characterized as an oncogenic long non-coding RNA (lncRNA) in several cancers including papillary thyroid cancer (PTC), but its role in PTC has not been fully elucidated. Considering the critical role of lncRNAs in cancer biology, further functional analysis of MCM3AP-AS1 in PTC may provide novel insights into PTC management. Subjects and methods: Paired tumor and non-tumor tissues were collected from 63 papillary thyroid carcinoma (PTC) patients. Expression levels of MCM3AP-AS1 , miR-218 and GLUT1 in tissue samples were analyzed by qRT-PCR. Cell transfection was performed to explore the interactions among MCM3AP-AS1 , miR-218 and GLUT1 . Cell proliferation assay was performed to evaluate the effects of MCM3AP-AS1 and miR-218 on cell proliferation. Results: MCM3AP-AS1 accumulated to high levels in PTC tissues and was affected by clinical stage. MCM3AP-AS1 showed a positive correlation with GLUT1 across PTC tissues. RNA interaction prediction showed that MCM3AP-AS1 could bind to miR-218 , which can directly target GLUT1 . MCM3AP-AS1 and miR-218 showed no regulatory role regulating the expression of each other, but overexpression of MCM3AP-AS1 upregulated GLUT1 and enhanced cell proliferation. In contrast, overexpression of miR-218 downregulated GLUT1 and attenuated cell proliferation. In addition, miR-218 suppressed the role of MCM3AP-AS1 in regulating the expression of GLUT1 and cell proliferation. Conclusions: MCM3AP-AS1 may serve as a competing endogenous RNA of miR-218 to upregulate GLUT1 in PTC, thereby promoting cell proliferation. The MCM3AP-AS1/miR-218/GLUT1 pathway characterized in the present study might serve as a potential target to treat PTC.

Abstract Gallstones disease is classified as cholesterol, pigment and mixed gallstones. Pigment gallstones is a common disease, and some patients experienced complications such as biliary pain and cholecystitis. Defatted walnut powder extract (DWPE) is extracted from the main by-product after oil extraction of the functional food walnut and can treat cholesterol gallstones. However, the effect of DWPE on pigment gallstones has not been reported. Thus, this paper aimed at exploring the potential mechanism of alleviating pigment gallstones and the metabolism of DWPE in vitro by UPLC-Q-Exactive Orbitrap MS to elucidate potential pharmacodynamic substances. It was found that DWPE significantly reduced the incidence of gallstones, the contents of unconjugated bilirubin and calcium, the inflammation of gallbladder tissue, the edema and congestion of gallbladder tissue, and the infiltration of inflammatory cells. In metabolism, a total of 35 metabolites of DWPE, including its main compounds ellagic acid and glansreginin A, were characterized in the intestine with various metabolic reactions. Presumably, the small molecular compounds generated after the metabolism by intestinal bacteria may be the pharmacodynamic substances of DWPE on pigment gallstones. This study revealed the effect of DWPE in treating pigment gallstones and their metabolism in vitro.

ABSTRACT Purpose: To investigate the role of renal denervation (RDN) on endogenous ouabain (EO) secretion in spontaneously hypertensive rats (SHR). Methods: Sixteen 12-week-old male SHR were randomly separated into the renal denervation group (RDNX group) and sham operation group (sham group), and eight age-matched Wistar Kyoto rats (WKY) were served as control group. EO concentrations, the Na+- K+-ATPaseactivity, and the expression of Na+-K+-ATPase were assessed. Results: EO levels in serum, kidneys and hypothalamus of sham group were higher than in RDNX group (p < 0.05). Renal Na+-K+-ATPase activity subjected to denervation surgery showed significantly reduction when compared with the sham groups (p < 0.05). A positive correlation existed between norepinephrine (NE) content and Na+-K+-ATPase activity in the kidney (r2 = 0.579). Renal Na+-K+-ATPase α1 subunit mRNA expression was down-regulated in the RDNX group compared with the sham group (P < 0.05), while renal Na+-K+-ATPase α1 subunit mRNA expression was no statistical significance between the groups (P = 0.63). Immunohistochemical analysis showed that there were significant differences in the renal expression of Na+-K+-ATPasebetween the three groups (P < 0.05). Conclusions: These experiments demonstrate that RDN exerted an anti-hypertensive effect with reduction of EO levels and Na+-K+-ATPase activity and Na+-K+-ATPase α1 subunit expression of kidney in SHR.

Abstract A simple and selective liquid chromatography tandem with mass spectrometry (LC-MS/ MS) method for quantification of lobetyolin in rat plasma was developed and validated. Chromatographic separation was achieved on a Thermo ODS C18 reversed-phase column using 0.1% aqueous formic acid-methanol (50:50, v/v) in an isocratic elution mode at a flow rate of 0.4 mL.min-1. LC/MS performance was done in a positive ion ESI mode and the MS/MS transitions were monitored at m/z 419.3 [M+Na]+ → m/z 203.1 for lobetyolin and m/z 394.9 [M+Na]+ → m/z 231.9 for IS, respectively. The assay exhibited a linear dynamic range over 1.0-500 ng.mL-1 for lobetyolin in plasma. Both the precision (%RSD) and accuracy (RE%) were within acceptable criteria (<15%). Recoveries ranged from 87.0% to 95.6%, and the matrix effects were from 91.0% to 101.3%. After oral administration, the peak plasma concentration of lobetyolin was obtained as 60.1 ng.mL-1 at 1.0 h. The proposed LC-MS/MS method could be applied to a pharmacokinetic study employing 66 samples from 6 Wistar rats.

Abstract In this study, we aimed to compare clinical efficacy of laparoscopic surgery and open surgery for colorectal cancer in the Huaihe River Basin in China. A total of 92 patients with colorectal cancer were selected as subjects. Patients were divided into control group (open surgery, n = 27 cases) and test group (laparoscopic surgery, n = 28 cases). Our results showed that the duration of operation (122.54 ± 14.85) min and length of incision (4.51 ± 1.065) cm were shorter in the experimental group than those in the control group. The intraoperative blood loss of the experimental group was (161.12 ± 10.694) ml, which was less than that of the control group (218.53 ± 15.369) ml (P < 0.05). Patients in the experimental group have higher Five-year survival rate and lower incidence of postoperative complications than those in the control group (all P < 0.05). In conclusion, in the treatment of colorectal cancer, laparoscopic surgery has a better clinical effect than open surgery, which is worthy of clinical application.

Abstract In order to obtain the extraction process of defatted walnut powder (DWP), an ultrasound-assisted extraction based on artificial neural network was established, and the activity of the extract was evaluated. The artificial neural network (ANN) was used to model different parameters, including the yield of extraction, the concentrations of glansreginin A and ellagic acid, and obtained the optimal extraction process: solvent to material ratio of 9.5 mL/g, ethanol concentration of 68%, extraction period of 55 min, and extraction three times. Then, the antioxidant scavenging ability of DWP obtained by ANN was compared with other extraction methods. The results showed that DWP extracted by artificial neural network demonstrated good activity in scavenging DPPH and ABTS radicals.

Abstract To investigate the safety and efficacy of intraoperative intraperitoneal chemotherapy in treating advanced gastric cancer. A randomized controlled trial (RCT) of gastric cancer surgery combined with intraoperative intraperitoneal chemotherapy for the efficacy and safety were screened by computer search PubMed, Medline, Springer, Elsevier Science Direct, Weipu, Wanfang and China National Knowledge Infrastructure (CNKI) with the last report up to October 2019. The control group underwent radical gastrectomy, and the experimental group underwent intraoperative intraperitoneal chemotherapy and radical gastrectomy. A total of 997 (Experimental group 453; Control group 544) participants were considered in this meta-analysis. Compared with the control group, the experimental group has higher 1-year survival rate [OR=2.40, 95%CI (1.34, 4.33), P=0.003], 2-year survival rate [OR=3.45, 95%CI (2.08, 5.75), P<0.00001], 3-year survival rate [OR=2.70, 95%CI (2.05, 3.54), P<0.00001] and 5-year survival rate [OR=2.90, 95%CI (1.93, 4.37), P<0.00001]. There is no significant difference in postoperative bleeding (P=0.95), postoperative infection (P=0.26), postoperative anastomotic leakage (P=0.41), and postoperative intestinal obstruction (P=0.11). Intraoperative intraperitoneal chemotherapy with advanced gastric cancer in the Chinese population can improve patients’ survival rate after surgery and does not increase the incidence of postoperative complications, so it is clinically significant and safe.

Abstract Resin AB-8 was screened from seven resins with different polarity and particle size because of its better decoloration and deproteinization efficiency to polysaccharide from the root of Actinidia valvata (AvPs), and then the optimized parameter conditions were applied by the single-factor experiments and were shown as follows: a concentration of crude polysaccharide of 3 mg/mL, an adsorption time of 40 min, an initial pH of 7.0, a flow rate of 1.5 BV/h. In addition, the results of HPGPC, FT-IR, PMP-HPLC-DAD, 1H NMR and Congo red test showed that the sugar chain, structural group, monosaccharide composition and triple-helix conformation structure of AvPs were not broken during resin AB-8 treatment. Moreover, AvPs could keep the stability of biological activity after the resin AB-8 treatment, and revealed an obviously antioxidant and anticancer activities in vitro as well. This research suggests that this method is promising for the deproteinization and decolorization of AvPs which could be explored as a potential antioxidant or anticancer agent for use in functional food or medicine.

Abstract Background: The MVD gene mutations are identified in porokeratosis, which is considered a skin-specific autoin- flammatory keratinization disease. However, the biological function of MVD gene remains largely unknown. Therefore, we analyzed the function of mvda gene, orthologous to the human MVD gene, in developing zebrafish. Methods: Morpholino antisense oligonucleotide technique was used to generate mvda loss-of-function phenotypes. Knockdown of mvda was confirmed by RT-PCR and Sanger sequencing. Scanning and transmission electron microscopy were performed to analyze the morphology of the epidermis. Angiogenesis study was presented using the Tg(fli1a:EGFP)yl transgenic strain. In addition, acridine orange staining was used to examine the apoptotic cells in vivo. Results: As expected, the mvda morphants showed abnormal morphology of the epidermis. Moreover, we observed ectopic sprouts in trunk angiogenesis and impaired formation of the caudal vein plexus in the mvda-deficient zebrafish. Besides, increased apoptosis was found throughout the tail, heart, and eyes in mvda zebrafish morphants. Conclusions: These findings indicated the essential role of mvda in the early development of zebrafish. This was the first in vivo knockdown study of the zebrafish mvda gene, which might offer insight into the biological function of the human MVD gene.

A series of experiments was conducted through a full-scale subsurface wastewater infiltration system (SWIS) to investigate the impact of hydraulic loading rate (HLR), organic loading rate (OLR) and underground temperature on nutrient removal and microbial settlement. Taking the hydraulic and treatment performance into consideration, HLR of 0.10 m³/(m²·d) was recommended with average NH3-N, TN, COD and TP removal rates of 82.6%, 81.5%, 80.9% and 90.9%, respectively. Considering treatment performance, OLR of 10.4 g BOD/(m²·d) was recommended with average NH3-N, TN, COD and TP removal rates of 88.1%, 84.8%, 86.3% and 91.3%, respectively. The number of nitrifying bacteria in each layer in the matrix decreased with increasing HLR, and the number of denitrifying bacteria increased with increasing HLR, at 0.8 and 1.0 m depths. When OLR increased, the number of bacteria and denitrifying bacteria at 0.8 and 1.0 m depths increased, and the number of nitrifying bacteria decreased. Average NH3-N, TN and COD removal rates increased with underground temperature increasing. The number of bacteria, nitrifying bacteria at 0.4 and 0.6 m depths and denitrifying bacteria at 0.8 and 1.0 m depths, increased with underground temperature increasing.

Abstract Purpose: To investigate whether oxymatrine (OMT) prevents hepatic fibrosis in rats by regulating liver transforming growth factor β1 (TGF-β1) level. Methods: Hepatic fibrosis was induced in rats by thioacetamide (TAA). Blood was collected at the end of week 12 to determine the levels of alanine aminotransferase (ALT), aspartate aminotransferase (AST), and glutathione (GSH). Changes in liver tissue were observed after hematoxylin-eosin (HE) staining. Results: Fibrosis was confirmed by Masson’s collagen staining. Liver TGF-β1 level was determined by ELISA. OMT significantly reduced serum ALT and AST but increased GSH levels in rats with hepatic fibrosis. Moreover, it significantly improved liver histology in rats with TAA-induced hepatic fibrosis. It significantly decreased liver TGF-β1 level compared to that in the untreated group. It also significantly reduced collagen deposition in rats. Conclusion: Oxymatrine is effective in protecting rats from thioacetamide-induced hepatic fibrosis by regulating TGF-β1 expression.
