Research on the prognostic value of adjusting intraperitoneal threedimensional quality evaluation mode in laparoscopic cholecystectomy patients

BACKGROUND Benign gallbladder diseases have become a high-prevalence condition not only in China but also worldwide.The main types of benign gallbladder diseases include gallbladder polyps,acute and chronic cholecystitis,and gallstones,with gallstones being the most common,accounting for over 70%of cases.Although the mortality rate of benign gallbladder diseases is low,they carry obvious potential risks.Studies have shown that an increased incidence of benign gallbladder diseases can increase the risk of cardiovascular diseases and gallbladder cancer,resulting in a substantial disease burden on patients and their families.AIM To assess the medical utility of the Configuration-Procedure-Consequence(CPC)three-dimensional quality evaluation model in modulating the prognosis of laparoscopic cholecystectomy patients.METHODS A total of 98 patients who underwent laparoscopic cholecystectomy in our hospital from February 2020 to January 2022 were selected as the subjects.According to the random number table method,they were divided into a study group and a control group,with 49 patients in each group.The control group received routine perioperative care,while the study group had the addition of the CPC three-dimensional quality evaluation.The postoperative recovery-related indicators(time to first flatus,time to oral intake,time to ambulation,hospital stay),stress indicators(cortisol and adrenaline levels),distinctions in anxiety and RESULTS The time to first flatus,time to oral intake,time to ambulation,and hospital stay of the study group patients were obviously lower than those of the control group patients,with statistical significance(P<0.05).On the 1st day after admission,there were no obvious distinctions in cortisol and adrenaline levels in blood samples,as well as in the Self-Rating Anxiety Scale(SAS)and Self-Rating Depression Scale(SDS)scores between the study group and the control group(P>0.05).However,on the 3rd day after surgery,the cortisol and adrenaline levels,as well as SAS and SDS scores of the study group patients,were obviously lower than those of the control group patients(P<0.05).The study group had 2 cases of incisional infection and 1 case of pulmonary infection,with a total incidence of complications of 6.12%(3/49),which was obviously lower than the 20.41%(10/49)in the control group(P<0.05).CONCLUSION Implementing the CPC three-dimensional quality evaluation model for patients undergoing laparoscopic cholecystectomy can help accelerate their perioperative recovery process,alleviate perioperative stress symptoms,mitigate anxiety,depression,and other adverse emotions,and to some extent,reduce the incidence of perioperative complications.

Association of serum interleukin-6 with negative symptoms in stable early-onset schizophrenia

BACKGROUND Accumulating evidence suggests that the inflammatory cytokine interleukin-6(IL-6)contributes to the pathophysiology of psychiatric disorders.However,there was no study concerning the relationship between IL-6 concentrations and clinical features in the chronic phase of early-onset schizophrenia(EOS).AIM To investigate the relationship between serum IL-6 concentration and the clinical features of EOS.METHODS We measured serum IL-6 Levels from 74 patients with chronic schizophrenia,including 33 with age at onset<21 years(EOS group)and 41 with onset≥21 years in[adult-onset schizophrenia(AOS)group],and from 41 healthy controls.Symptom severities were evaluated using the Positive and Negative Syndrome Scale(PANSS).RESULTS Serum IL-6 concentrations were higher in both EOS and AOS groups than healthy controls(F=22.32,P<0.01),but did not differ significantly between EOS and AOS groups(P>0.05)after controlling for age,body mass index,and other covariates.Negative symptom scores were higher in the EOS group than the AOS group(F=6.199,P=0.015).Serum IL-6 concentrations in the EOS group were negatively correlated with both total PANSS-negative symptom score(r=-0.389,P=0.032)and avolition/asociality subscore(r=-0.387,P=0.026).CONCLUSION Patients with EOS may have more severe negative symptoms than those with adult-onset schizophrenia during the chronic phase of the illness.IL-6 signaling may regulate negative symptoms and its avolition/asociality subsymptoms among the early-onset chronic schizophrenic patients.

Cell-free plasma hypermethylated CASZ1, CDH13 and ING2 are promising biomarkers of esophageal cancer

Identifying sensitive and specific biomarkers for early detection of cancer is immensely imperative for early diagnosis and treatment and better clinical outcome of cancer patients. This study aimed to construct a specific DNA methylation pattern of cancer suppressor genes and explore the feasibility of applying cell-free DNA based methylation as a biomarker for early diagnosis of esophageal squamous cell carcinoma(ESCC). We recruited early stage ESCC patients from Yangzhong County, China. The Illumina Infinium 450 K Methylation BeadChip was used to construct a genome-wide DNA methylation profile. Then, differentiated genes were selected for the validation study using the Sequenom MassARRAY platform. The frequency of methylation was compared between cancer tissues, matched cell-free DNAs and normal controls. The specific methylation profiles were constructed, and the sensitivity and specificity were calculated. Seven CG sites in three genes CASZ1, CDH13 and ING2 were significantly hypermethylated in ESCC as compared with normal controls. A significant correlation was found between the methylation of DNA extracted from cancer tissues and matched plasma cell-free DNA, either for individual CG site or for cumulative methylation analysis. The sensitivity and specificity reached 100% at an appropriate cut-point using these specific methylation biomarkers. This study revealed that aberrant DNA methylation is a promising biomarker for molecular diagnosis of esophageal cancer. Hypermethylation of CASZ1,CDH13 and ING2 detected in plasma cell-free DNA can be applied as a potential noninvasive biomarker for diagnosis of esophageal cancer.

Gai1/3 mediation of Akt-mTOR activation is important for RSPO3-induced angiogenesis

Dear Editor,R-spondin3(RSPO3)is essential for vascular development and angiogenesis.Analyzing RSPO3-knockout embryos revealed severe vascular defects in the placenta(Aoki et al.2007).In both Xenopus and murine embryos,RSPO3 KO led to significant vascular defects(Kazanskaya et al.2008)and embryonic death(Kazanskaya et al.2008).In the placenta,RSPO3 could promote vascular endothelial growth factor(VEGF)expression(Kazanskaya et al.2008).RSPO3 is a ligand of low-density lipoprotein receptor-related protein 6(LRP6)and leucine-rich repeat G protein-coupled receptor 4(LGR4)to form a multiple ligands-receptors-cluster with Wnt and frizzled(FzD),thereby activating and amplifying downstreamβ-catenin signaling(in and Yoon 2012;Tocci et al.2020).

Enhanced treatment for cerebral ischemia-reperfusion injury of puerarin loading liposomes through neutrophils-mediated targeted delivery

The recovery of blood circulation following cerebral infarction-associated thrombolysis brings new damage to the brain,which is cerebral ischemia-reperfusion injury(CIRI).Inflammation is the main pathological mechanism of CIRI.The inflammatory response triggered by cerebral ischemia-reperfusion provides neutrophils with a special opportunity to facilitate drug delivery to the site of ischemic penumbra through the chemotaxis of inflammatory factors by neutrophils.Puerarin is an isoflavone derivative with a significant neuroprotective effect in vitro.But the blood-brain barrier(BBB)impedes its therapeutic efficacy on CIRI within the brain.Inspired by the pathological process,we have used neutrophils as carriers to enhance the BBB penetration of liposomes loaded with puerarin and improve the concentration of puerarin in the brain parenchyma in this study.These results showed that puerarin-containing liposomes were released in response to inflammatory conditions associated with brain injury to enhance the neuroprotection effect at the ischemic penumbra.

A gold(Ⅰ)-catalyzed three-component reaction of β-nitrostyrenes with 1,3-dicarbonyl compounds and primary amines to form polysubstituted pyrroles has been developed at room temperature in ethanol.The key advantages of the three-component reaction are the mild reaction conditions and environmentally safer solvent.

Hypoxia-induced ROS aggravate tumor progression through HIF-1α-SERPINE1 signaling in glioblastoma

Hypoxia,as an important hallmark of the tumor microenvironment,is a major cause of oxidative stress and plays a central role in various malignant tumors,including glioblastoma.Elevated reactive oxygen species(ROS)in a hypoxic microenvironment promote glioblastoma progression;however,the underlying mechanism has not been clarified.Herein,we found that hypoxia promoted ROS production,and the proliferation,migration,and invasion of glioblastoma cells,while this promotion was restrained by ROS scavengers N-acetyl-L-cysteine(NAC)and diphenyleneiodonium chloride(DPI).Hypoxia-induced ROS activated hypoxia-inducible factor-1α(HIF-1α)signaling,which enhanced cell migration and invasion by epithelial-mesenchymal transition(EMT).Furthermore,the induction of serine protease inhibitor family E member 1(SERPINE1)was ROS-dependent under hypoxia,and HIF-1αmediated SERPINE1 increase induced by ROS via binding to the SERPINE1 promoter region,thereby facilitating glioblastoma migration and invasion.Taken together,our data revealed that hypoxia-induced ROS reinforce the hypoxic adaptation of glioblastoma by driving the HIF-1α-SERPINE1 signaling pathway,and that targeting ROS may be a promising therapeutic strategy for glioblastoma.

Pseudomonas aeruginosa-induced mitochondrial dysfunction inhibits proinflammatory cytokine secretion and enhances cytotoxicity in mouse macrophages in a reactive oxygen species(ROS)-dependent way

Pseudomonas aeruginosa belongs to the genus Pseudomonas and is a common Gram-negative,exclusively aerobic,conditionally pathogenic bacterium with the characteristics of easy colonization,mutation,and multidrug resistance(Deng et al.,2015;Azam and Khan,2019;Jurado-Martin et al.,2021).

Serum mitochondrial tsRNA serves as a novel biomarker for hepatocarcinoma diagnosis

Hepatocellular carcinoma(HCC),which makes up the majority of liver cancer,is induced by the infection of hepatitis B/C virus.Biomarkers are needed to facilitate the early detection of HCC,which is often diagnosed too late for effective therapy.The tRNA-derived small RNAs(tsRNAs)play vital roles in tumorigenesis and are stable in circulation.However,the diagnostic values and biological functions of circulating tsRNAs,especially for HCC,are still unknown.In this study,we first utilized RNA sequencing followed by quantitative reverse-transcription PCR to analyze tsRNA signatures in HCC serum.We identified tRF-Gln-TTG-006,which was remarkably upregulated in HCC serum(training cohort:24 HCC patients vs.24 healthy controls).In the validation stage,we found that tRF-Gln-TTG-006 signature could distinguish HCC cases from healthy subjects with high sensitivity(80.4%)and specificity(79.4%)even in the early stage(Stage I:sensitivity,79.0%;specificity,74.8%;155 healthy controls vs.153 HCC patients from two cohorts).Moreover,in vitro studies indicated that circulating tRF-Gln-TTG-006 was released from tumor cells,and its biological function was predicted by bioinformatics assay and validated by colony formation and apoptosis assays.In summary,our study demonstrated that serum tsRNA signature may serve as a novel biomarker of HCC.
