Screening and bioinformatics analysis of key autophagy-related genes in alcoholic hepatitis / 器官移植

Objective To screen key autophagy-related genes in alcoholic hepatitis (AH) and investigate potential biomarkers and therapeutic targets for AH. Methods Two AH gene chips in Gene Expression Omnibus (GEO) and autophagy-related data sets obtained from MSigDB and GeneCards databases were used, and the key genes were verified and obtained by weighted gene co-expression network analysis (WGCNA). The screened key genes were subject to gene ontology (GO), Kyoto Encyclopedia of Genes and Genomes (KEGG), protein-protein interaction (PPI) and immune infiltration analyses. Messenger RNA (mRNA)- microRNA (miRNA) network was constructed to analyze the expression differences of key autophagy-related genes during different stages of AH, which were further validated by real-time fluorescence quantitative polymerase chain reaction (RT-qPCR) in the liver tissues of AH patients and mice. Results Eleven autophagy-related genes were screened in AH (EEF1A2, CFTR, SOX4, TREM2, CTHRC1, HSPB8, TUBB3, PRKAA2, RNASE1, MTCL1 and HGF), all of which were up-regulated. In the liver tissues of AH patients and mice, the relative expression levels of SOX4, TREM2, HSPB8 and PRKAA2 in the AH group were higher than those in the control group. Conclusions SOX4, TREM2, HSPB8 and PRKAA2 may be potential biomarkers and therapeutic targets for AH.

Integrated bioinformatics approach reveals methylation-regulated differentially expressed genes in obesity

ABSTRACT Objective: To identify DNA methylation and gene expression profiles involved in obesity by implementing an integrated bioinformatics approach. Materials and methods: Gene expression (GSE94752, GSE55200, and GSE48964) and DNA methylation (GSE67024 and GSE111632) datasets were obtained from the GEO database. Differentially expressed genes (DEGs) and differentially methylated genes (DMGs) in subcutaneous adipose tissue of patients with obesity were identified using GEO2R. Methylation-regulated DEGs (MeDEGs) were identified by overlapping DEGs and DMGs. The protein-protein interaction (PPI) network was constructed with the STRING database and analyzed using Cytoscape. Functional modules and hub-bottleneck genes were identified by using MCODE and CytoHubba plugins. Functional enrichment analyses were performed based on Gene Ontology terms and KEGG pathways. To prioritize and identify candidate genes for obesity, MeDEGs were compared with obesity-related genes available at the DisGeNET database. Results: A total of 54 MeDEGs were identified after overlapping the lists of significant 274 DEGs and 11,556 DMGs. Of these, 25 were hypermethylated-low expression genes and 29 were hypomethylated-high expression genes. The PPI network showed three hub-bottleneck genes (PTGS2, TNFAIP3, and FBXL20) and one functional module. The 54 MeDEGs were mainly involved in the regulation of fibroblast growth factor production, the molecular function of arachidonic acid, and ubiquitin-protein transferase activity. Data collected from DisGeNET showed that 11 of the 54 MeDEGs were involved in obesity. Conclusion: This study identifies new MeDEGs involved in obesity and assessed their related pathways and functions. These results data may provide a deeper understanding of methylation-mediated regulatory mechanisms of obesity.

Helicobacter pylori and non-alcoholic fatty liver disease: Is there a relationship?

Non-alcoholic fatty liver disease (NAFLD) is distinguished by liver injury due to metabolic stress, identified by diffuse hepatocyte macrovascular fatty lesions [1]. The prevalence of NAFLD is rising yearly, with a worldwide incidence rate between 20% and 30% [2]. Complex hereditary variables, improper lipid metabolism, and insulin resistance are the key characteristics of the etiology of NAFLD [3]. The research has revealed that aberrant lipid metabolism in the liver can result in dysbacteriosis in the intestinal flora; abnormality of the flora eventually encourages lipid deposition in the liver. Additionally, there is mounting proof that NALFD is linked to abnormalities in the gut flora, particularly Helicobacter pylori (H, pylori) [4]. Gram-negative bacillus, termed H pylori, has colonized the deep layers of the gastric mucosa. [5]. The global infection rate for H pylori is about 50% or higher [6]. According to research, H pylori causes gastric cancer, gastrointestinal lymphoma, peptic ulcers, and chronic gastritis [7]. Additionally, some researchers indicate a connection between H pylori and liver cancers, diabetes, and improper lipid metabolism [8]. Some studies have discovered that infection by H pylori is one of the elements for NAFLD to progress and that getting rid of H pylori can partially stop the evolution of NAFLD [9].

Review on data analysis and application of high-throughput peptide arrays / 上海预防医学

This article introduces a high-throughput molecular screening chip： peptide arrays. As a kind of biochip， the peptide arrays are easy to synthesis， stable in probe chemistry， high-throughput in screening and highly specific compared with other biochips. To analyze the new high-throughput data， researchers have recently proposed a series of deep learning and bioinformatics methods to study the binding characteristics of peptide probes and target molecules. Those algorithms could be used to predict the binding affinity of protein targets against peptides. Moreover， peptide arrays could also play important roles in analyzing protein-protein interactions，screening novel drug peptides， disease diagnosis and general health assessment based on recent reports. The application of this new technology could provide novel insights into public health research.

Role of PPI and importance of anti-reflux agents in the treatment of NERD

Background: Esomeprazole, an S-isomer of omeprazole, is a much more potent acid inhibitor than most other currently available PPIs and gives excellent results. Therefore, it is a first-line drug for acid-related diseases like NonErosive Reflux Disease (NERD). Yet, patients demand faster onset and response. Aim : To establish the role of esomeprazole and the importance of anti-reflux agents like a combination of two antacids (calcium carbonate and sodium bicarbonate) and alginate in treating NERD. Conclusion: Esomeprazole therapy shows potential efficacy in the continuous maintenance treatment of the NERD. However, it is suggested that to improve the efficiency of esomeprazole for the treatment of NERD; we can supplement the drug with antacids (sodium bicarbonate and calcium carbonate) and alginates.

Upper gastrointestinal bleeding in mechanically ventilated patients in medical ICU: A single-center study

Aims Upper Gastrointestinal bleeding (UGIB) in critically ill patients under mechanical ventilation (MV) is a significant cause of morbidity and mortality. Therefore, it aimed to study the incidence, predictors, and etiology of UGIB in critically ill patients under MV. Patients and Methods Three hundred and sixty critically ill patients were managed by mechanical ventilation. The patients were evaluated by complete clinical examination, APACHE II score, liver and kidney function tests, and abdominal ultrasound. In addition, upper gastrointestinal endoscopy was done for survived patients with UGIB during MV after weaning with a stable clinical condition for at least 48 hours. Results 41 patients (11.4 %) had UGIB; 15 patients (36.6%) survived and death occurred in 26 (63.4%). Upper endoscopy revealed large ulcers > 2 cm in the gastric antrum (n=1), multiple antral ulcers (n=2), large >2cm corporeal gastric ulcers (n=2) [all were Forrest Ib with oozing surface], bleeding small duodenal bulb ulcers < 2cm (n=1) [Forrest Ia with spurting], small ulcers in the lower esophagus with lower end esophagitis (n=2), black esophagus (n=1), ulcer on top of grade III oesophageal varices (n=2), severe portal hypertensive gastropathy (n=3), candida esophagitis and gastritis (n=1). Logistic regression analysis revealed that the independent variables of UGIB were elevated serum creatinine, APACHE II score >14, peak inspiratory pressure ≥ 30cmH2O, and prolonged aPTT. Conclusions : Mechanically ventilated patients had a high risk of upper gastrointestinal bleeding, which the postulated parameters can predict for adequate prophylaxis.

Impact of treatment optimization in patients with gastroesophageal reflux disease who do not respond to esomeprazole / Impacto de la optimización del tratamiento en pacientes con enfermedad por reflujo gastroesofágico que no responden a esomeprazol

Abstract Introduction: gastroesophageal reflux disease (GERD) affects one out of eight people in Colombia. Its characteristic symptoms are heartburn and reflux. The cornerstone of treatment is proton pump inhibitors (PPIs), with a clinical response in 58-80% of patients. Of those who do not respond, 75-90% have a superimposed functional disorder and could be treated by adding visceral neuromodulators. Objective: to evaluate the impact of optimizing the treatment of patients with GERD when there is no response to esomeprazole (ESO). Materials and methods: a prospective study in patients with no clinical response (more than two reflux episodes per week) who were treated with 40 mg of ESO half an hour before breakfast along with the recommendation to lose weight if BMI >25, stop smoking and manage stress; and, finally, increasing the ESO dose to 40 mg on an empty stomach and before dinner. When all of this was done and symptoms persisted, 12.5 mg of amitriptyline were added at night. The response was evaluated every 12 weeks. Results: a total of 529 patients were eligible and 149 met the inclusion criteria. With treatment optimization, 111 patients had a clinical response without using amitriptyline (74.5%; 95%CI 67.2 81.4). Amitriptyline was added in 22 patients (14.8%), 15 of whom responded (68.2%; 95%CI 47.04-89.32%). Eight patients experienced drowsiness (53.3%). A relationship was found between PPI treatment compliance and clinical response (p<0.0001). Conclusions: in patients with GERD, PPI treatment optimization improves 74.5% (95%CI 67.2 81.4) of the patients, and adding amitriptyline for those who do not improve achieves improvement in 68.2% of those who did not improve with two doses of ESO. Sequential management achieved a cumulative improvement in symptom control in 85% (95%CI 78.6-90.4) of the patients. (Acta Med Colomb 2021; 46. DOI: https://doi.org/10.36104/amc.2021.2041).

Resumen Introducción: la enfermedad por reflujo gastroesofágico (ERGE) afecta a una de cada ocho personas en Colombia. Sus síntomas característicos son pirosis y regurgitación. La piedra angular del tratamiento son los inhibidores de bomba de protones (IBP) con respuesta clínica en 58-80%. En quienes no responden 75-90% tienen un trastorno funcional superpuesto y se podrían tratar adicionando neuromoduladores viscerales.

Se encontró relación entre el cumplimiento del tratamiento con IBP y la respuesta clínica (p<0.0001). Conclusiones: en pacientes con ERGE la optimización del tratamiento con IBP mejora el 74.5% (IC95% 67.2-81.4) de los pacientes y la adición de amitriptilina a quienes no mejoran, logra mejorar el 68.2% de quienes no mejoraban con dos dosis de ESO. Con el manejo secuencial se logró mejoría acumulativa en el control de los síntomas de 85% (IC95% 78.6-90.4) de los pacientes. (Acta Med Colomb 2021; 46. DOI:https://doi.org/10.36104/amc.2021.2041).

Transcriptional profiling and network pharmacology analysis identify the potential biomarkers from Chinese herbal formula Huosu Yangwei Formula treated gastric cancer in vivo / 中国天然药物

Huosu Yangwei (HSYW) Formula is a traditioanl Chinese herbal medicine that has been extensively used to treat chronic atrophic gastritis, precancerous lesions of gastric cancer and advanced gastric cancer. However, the effective compounds of HSYW and its related anti-tumor mechanisms are not completely understood. In the current study, 160 ingredients of HSYW were identified and 64 effective compounds were screened by the ADMET evaluation. Furthermore, 64 effective compounds and 2579 potential targets were mapped based on public databases. Animal experiments demonstrated that HSYW significantly inhibited tumor growth in vivo. Transcriptional profiles revealed that 81 mRNAs were differentially expressed in HSYW-treated N87-bearing Balb/c mice. Network pharmacology and PPI network showed that 12 core genes acted as potential markers to evaluate the curative effects of HSYW. Bioinformatics and qRT-PCR results suggested that HSYW might regulate the mRNA expression of DNAJB4, CALD, AKR1C1, CST1, CASP1, PREX1, SOCS3 and PRDM1 against tumor growth in N87-bearing Balb/c mice.

Strive to Improve the Eradication Rate of Helicobacter pylori / 胃肠病学

As the awareness of the harmfulness of Helicobacter pylori (Hp) infection increases, the indications for Hp eradication continue to expand. "Kyoto Global Consensus Report on Helicobacter pylori Gastritis" puts forward "Hp infected individuals should be offered eradication therapy, unless there are competing considerations" and the statement has been accepted by more and more scholars. In our country, "the confirmed Hp infection" has been listed as an indication for eradication. However, as the antibiotic resistance rate of Hp increases, the eradication rate of Hp is gradually decreasing, and the proportion of people who has failed multiple treatments is increasing. This article was specially written for helping the clinicians to improve the eradication rate of Hp infection.

Almagate suspension spraying to treat the endoscopic submocosal dissection-induced gastric ulcers: A single-center randomized study / 西安交通大学学报(医学版)

Objective To evaluate the efficacy and safety of magnesium aluminum suspension spraying in treating gastric ulcer after endoscopic submocosal dissection (ESD). Methods We made a prospective analysis of patients with gastric ESD surgery performed between January 2016 and June 2019. They were divided into control group, spraying group, and spraying + oral group on the basis of treatment method. All patients were followed up for 8 weeks to evaluate endoscopic ulcer healing and recovery rate. At the same time, postoperative symptoms and complications such as bleeding were also recorded. SPSS 24.0 software was used for statistical analysis. Results A total of 330 eligible cases were randomly divided into control group (124 cases), spraying group (108 cases), and spraying + oral group (98 cases). The results showed that the postoperative pain incidence in spraying group and spraying + oral group was significantly better than that in the control group (35.48% vs. 17.59%, P<0.01; 35.48% vs. 20.41%, P=0.01). The 4-week ulcer recovery rate was better in spraying + oral group than in the control group. It should be noted that ulcer healing rate achieved 100% for the antrum of patients in spraying + oral group. At the same time, the incidence of postoperative bleeding decreased, and no significant adverse drug reactions were observed during the follow-up. Conclusion Almagate suspension spraying is safe and effective in the treatment of upper gastrointestinal ESD postoperative ulcer. In addition, it can also relieve postoperative pain.

Use and inappropriate use of proton pump inhibitors in hospitalized patients

Background: The discovery of Helicobacter pylori infection in etiology of peptic ulcer disease and proton pump inhibitors (PPI) in management of upper gastrointestinal diseases had been the milestones in medical science. PPI are currently being both overused and misused. In countries like India, where over 500 branded formulations of PPI are available, probability of misuse and abuse increases exponentially. The aim of the study was to find out inappropriate use of PPI, among hospitalized patients.Methods: In order to find answer to the research question a cross sectional study was conducted in indoor patient of a tertiary care private hospital at Jaipur, Rajasthan. Patients of either sex, aged 18 years or above belonging to rural and urban communities were participating in study. The sample size was 500.Results: It was noted that Inappropriate PPI use was observed in most of the hospital admitted patients (78%). Most common diagnosis among inappropriate PPI use was dengue fever (due to increased number of dengue cases during study period), followed by cerebrovascular accidents and urinary tract infection. Most common indication for appropriate PPI use was stress ulcer prophylaxis, again in dengue case (due to cardinal manifestation of thrombocytopenia).Conclusions: Almost all patients were once prescribed PPI after admission and discharged on PPI (99.2%). Thus, we recommend evidence-based prescription of PPI, to reduce side effects and excess cost.

Internal consistency and confirmatory validity of the parenting practices inventory in a Mexican population sample / Consistencia interna y validez confirmatoria del inventario de prácticas de crianza en una muestra de población mexicana

Abstract Introduction Parenting practices refer to specific behaviours used by parents and caretakers of children to guide childhood development and socialization goals. These practices are associated with children's health, psychological, and physical development. Objective To determine the psychometric properties of the Parenting Practices Inventory (PPI) among a group of child caregivers in Mexico City. Method The PPI was applied to 443 caregivers of children and adolescents, who attended a general health care centre in Mexico City. For the psychometric evaluation of the instrument, the full distribution and discrimination of the items was analysed first. Then, the validity of the construct was tested through an exploratory factor analysis and a confirmatory analysis with structural equation modelling. Results The internal consistency of the PPI showed α = .867 and 41.25% of variance explained for all four dimensions of interest. The confirmatory factor analysis showed that the model had goodness of fit. It included twenty-four items with adequate consistency and validity indices. Discussion and conclusion The PPI is therefore a potentially useful psychometric measure for evaluating parenting practices among this type of population and could have major implications for the development of interventions and preventive programmes. It provides scientific bases for diagnostic decision-making and primary health care from the moment of initial contact to specialized medical care.

Proton pump inhibitor: a risk factor for spontaneous bacterial peritonitis in Indian cirrhotics decompensated with ascites

Background: Spontaneous bacterial peritonitis (SBP) is common complication of cirrhosis caused by bacterial translocation. Bacterial colonization and overgrowth may occur in GI tract on suppression of gastric acid secretion. Beta-blockers have been postulated to reduce intestinal permeability. There is no significant Indian study to evaluate association of PPI with SBP in cirrhotic ascites. We aimed to assess the effect of PPI in cirrhotic patients decompensated with ascites.Methods: A retrospective case control study (January 2016 to April 2018), evaluated subjects with cirrhosis and ascites. Two study groups of cirrhotic subjects with and without SBP were formed. In each of the two study groups, 143 subjects, were enrolled by matching for age, year of admission, Child-Pugh-Turcotte (CTP) class after considering the inclusion and exclusion criteria. PPI use and various other correlates were compared in both study groups. SPSS ver 24.0 was used for statistical analysis.Results: About 69.23% subjects were using PPI prior to admission in SBP group, which was significant compared to only 31.47% in cirrhotics without SBP (p 0.003). On multivariate analysis PPI use was an independent risk factor for SBP (OR 2.24, 95% CI: 1.01-4.24; p value 0.033) and beta blocker use was protective (OR 0.58; 95% CI: 0.4-0.8; p 0.001).Conclusions: PPI use doubles the risk of development of SBP in cirrhotics decompensated with ascites. In contrast, Beta blockers use significantly lowers the risk of SBP.

Curcumae Longae Rhizoma,Curcumae Radix and Curcumae Rhizoma are different medicinal parts of the same plant.Nevertheless,they are different in medicinal effects due to the different Chinese herbal nature. In this study,traditional Chinese medicines database( TCMD2009),traditional Chinese medicine system( TCMSP),and Ch EMBL database were retrieved to screen the active components and targets,and construct the target PPI network. By a graph theoretic clustering algorithm identifying protein complex algorithm( IPCA),the protein modules were identified and analyzed by gene ontology( GO) enrichment. A comparative study of Curcumae Longae Rhizoma and Curcumae Radix illustrate that Curcumae Longae Rhizoma regulates blood coagulation through P2 RY12,GNG2 and other genes to exert the analgesic effect. Curcumae Radix regulates lipid metabolism,plasma lipoprotein particle levels,platelet activation,response to oxidative stress,apoptotic process through LDLR,APOB,PRKCA,SOD1,TP53 and other genes to perform a function in clearing the heart and cooling the blood. A comparative study of Curcumae Radix and Curcumae Rhizoma demonstrate that Curcumae Rhizoma on regulates the nervous system by GRIA2,GRIA4 and other genes to exert blood-breaking effect; Curcumae Radix regulates lipid metabolism,plasma lipoprotein particle levels,platelet activation,response to oxidative stress,apoptotic process by genes such as CALM1,LPL,APOB,SOD1 and TP53 to play the role of clearing heart and cooling blood. Cluster analysis of the protein interaction network of the nature combination is helpful to explain the intrinsic link between the nature combination and efficacy.

Cost variation analysis of proton pump inhibitors available in Indian market

Background: In now days proton pump inhibitors are prescribing more and more by Indian physicians not only in peptic ulcer,gastroesophageal reflux disease, gastritis but also along with non steroidal anti-inflammatory drugs to overcome the side effects as gastric irritation and discomfort by non steroidal anti inflammatory drugs.There are many brands of PPI drugs available in Indian market. Costly drugs can lead to economic burden which results in decreased compliance or even non-compliance. Non 朿ompliance leads to incomplete treatment which tends to increase morbidity.Increase in the patient medication cost was found to associated with decreased adherence to prescription medication.Hence this study was done to assess the cost variation of proton pump inhibitors [PPI] drugs.Methods: The maximum and minimum price of each brand of the drug in INR was noted by using CIMS January to April 2018 edition Drug Today April to June 2018 Vol-1. The cost ratio and the percentage cost variation for individual drug brands was calculated. The cost of 10 tablets/capsules was calculated in case of oral drug and the cost of one 1 vial or ampoule was noted in case of injectable drug. At last the cost ratio and percentage cost variation of various brands was compared.Results: Percentage variation in cost for proton pump inhibitors marketed in india was found to be tablet/capsule Esomeprazole [20mg]:141.17, tablet/capsule Esomeprazole [40mg]:196.29, capsule/tablet Omeprazole[20mg]: 569.53, Tablet/capsule Pantoprazole[40mg]: 248.8, tablet /capsule Rabeprazole[20mg]: 815.78, capsule/tablet Lansoprazole[30mg]: 173.33, Inj.

Investigation for molecular network and biological functions of Kuntai Capsule baesd on bioinformatics analysis / 中草药

Objective To investigate the potential molecular functions and the involved signaling network of Heyan®Kuntai Capsules (HYKTc) based on the ingredient-gene targets clustering by means of bioinformatics analysis. Methods The ingredients in HYKTc were obtained by the combination of previous LC-ESI-MS/MS method and searched through Traditional Chinese Medicine System Pharmacology databases. Further the gene ontology (GO) and KEGG enrichment analysis were performed with Database for Annotation, Visualization, and Integrated Discovery (DAVID) tools. Results A total of 29 chemicals were obtained in which 21 chemicals were identified by LC-ESI-MS/MS method. Afterwards, 186 gene targets were acquired in the databases. The HYKTc-gene targets clustering were highly enriched in central nervous system, breast, and ovary. Subsequent GO analysis showed that these gene targets were significantly located in the cytosol, mitochondria and extracellular matrix, mainly functioning as lipase, kinase and oxidoreductase activity. Besides, KEGG results found that these targets were involved in the PI3K-Akt, mTOR, and insulin signaling pathways. Conclusions Using TCM databases searching combined with bioinformatics methods, the potential explanations for the clinical efficiency of HYKTc were proveded for further clinical applications.

8．HTA is NICE for Cancer Patients? / 薬剤疫学

The recent developed medicine for various cancer types tends to be highly priced. If those expenssive medicines are sold for the large number of cancer patients with lung cancer, stomach cancer, colon cancer, etc, the nationwide health insurance systems covering every citizen would be no longer sustainable in Japan. Because of these concerns, the Central Social Insurance Medical Council ― an advisory body of the Health and Welfare minister ― have started discussions about HTA (health technology assessment) since 2005. And then, the assessment will start at next April. It is a very important assessment for keeping sustainability of the medical policy, but on the other side we find some issues which have to be solved, namely lack of human resources, lack of voices from patients and the public, and lack of transparency in policy making processes. HTA in Japan has been lagged compared to the Western countries, and I would expect many more new challenges in Japan and hope to see us learn from the past.

Cost-effectiveness Study of Celecoxib for Osteoarthritis in China / 中国药房

OBJECTIVE:To evaluate cost-effectiveness of celecoxib for osteoarthritis(OA)in China. METHODS:OA cost-ef-fectiveness analysis model developed by National Institute for Health and Clinical Excellence(NICE)was adopted using celecoxib, diclofenac+PPIs as control. Related risk Zof adverse event was from CONDOR trials.The effectiveness was measured by QALY. Costs and QALYs were discounted annually at 4.76%. RESULTS:Celecoxib had a cost of $3 591 and 8.826 QALYs while diclofe-nac+PPIs had a cost of $3 674 and 8.830 QALYs. The incremental costs and QALYs of celecoxib to diclofenac+PPIs were -$83 and -0.004 QALYs,respectively. The incremental cost-effectiveness ratio(ICER)for diclofenac+PPIs to celecoxib was$23 258/QALY. The results of single factor sensitivity analysis and probability sensitivity analysis showed that drug cost was driving factor of IC-ER,and the results of two therapy plans were similar. CONCLUSIONS:Celecoxib is a less costly alternative than diclofenac+PPIs. The difference in QALYs between celecoxib and diclofenac+PPIs is extremely small,so celecoxib is likely to be cost-effec-tive for OA patients.
