Formation of Droplets of Shear-Thinning Non-Newtonian Fluids in Asymmetrical Parallelized Microchannels.

Fluids containing polymers are frequently utilized in the chemical industry and exhibit shear-thinning characteristics. The flow distribution of non-Newtonian fluids in parallelized microchannels is a key issue to be solved during numbering-up. Numbering-up means increasing the number of parallelized microchannels. In this study, a high-speed camera is used to explore the distribution of fluid flow as well as the uniformity and stability of droplets in conceptual asymmetrical parallelized microchannels. Cyclohexane and carboxymethylcellulose sodium (CMC) aqueous solutions are used as the continuous phase and dispersed phase, respectively. The effects of fluctuation of pressure difference around the T-junction, the hydrodynamic resistance in microchannels, and the shear-thinning property of fluids on flow distribution and droplet formation are revealed. The uniformity and stability of droplets in microdevices with various cavity settings are compared, and an optimal configuration is proposed. Finally, prediction models for the flow distribution of shear-thinning fluids in asymmetrical parallelized microchannels are established.

Analysis of circRNAs profile in TNF-α treated DPSC.

BACKGROUND: Pulpitis often are characterized as sustained inflammation and impaired pulp self-repair. Circular RNAs (circRNAs) have been reported to be involved in the development of inflammation, but their influence in pulpitis is still unidentified, which was examined in our research. METHODS: In this study, TNF-α (20 ng/mL) was used to treat DPSCs, then MTS identified cell proliferation. The circRNAs profile in DPSCs with or without TNF-α treatment was evaluated using RNA sequencing and subsequently by bioinformatics analysis. After that, the circular structure was assessed using agarose gel electrophoresis, followed by Sanger sequencing. And the circRNAs expression was ratified using quantitative real-time polymerase chain reaction in cell and tissues samples. Additionally, the plausible mechanism of circRNAs was envisaged, and the circRNA-miRNA-mRNA linkage was plotted using Cytoscape. RESULTS: The treatment of TNF-α inhibited cell proliferation capabilities in DPSCs, which also made 1195 circRNA expressions undergo significant alterations. Among these changes, 11 circRNAs associated with inflammation were chosen for circular structure verification, and only seven circRNAs (hsa_circ_0001658, hsa_circ_0001978, hsa_circ_0003910, hsa_circ_0004314, hsa_circ_0004417, hsa_circ_0035915, and hsa_circ_0002545) had circular structure. Additionally, five circRNAs expressions (hsa_circ_0001978, hsa_circ_0003910, hsa_circ_0004314, hsa_circ_0004417, and hsa_circ_0035915) had significantly altered between with or without TNF-α treated DPSCs. Furthermore, hsa_circ_0001978 and hsa_circ_0004417 were increased in patients suffering from pulpitis. Furthermore, their ceRNA linkage and Kyoto Encyclopedia of Genes and Genomes analysis suggested that these two circRNAs may participate in the inflammation development of pulpitis via mitogen-activated protein kinase and the Wnt signaling pathway. CONCLUSION: This study revealed that the circRNAs profile was altered in TNF-α treated DPSCs. Also, hsa_circ_0001978 and hsa_circ_0004417 may be involved in the inflammation progress of pulpitis. These outcomes provided the latest information for additional research on pulpitis.

MicroRNA expression profiles in peri-miniscrew implant crevicular fluid in orthodontics: a pilot study.

BACKGROUND: This study systematically evaluated microRNA (miRNA) expression patterns in peri-miniscrew implant crevicular fluid (PMICF) in orthodontic patients. METHODS: Next-generation sequencing (NGS) was performed to obtain miRNA profiles in PMICF or gingival crevicular fluid (GCF) collected from 3 healthy volunteers (H), 3 peri-implantitis patients (PMSII) and 5 periodontitis patients (P). MiRNA expression patterns were compared between normal and orthodontic PMICF and GCF. Differentially expressed miRNAs were estimated by quantitative real-time PCR (qRT-PCR). Enrichment analyses of the gene targets controlled by these miRNAs were conducted by Gene Ontology (GO) enrichment and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway analyses. RESULTS: Compared with healthy donors, in PMSII patients, a total of 206 upregulated miRNAs and 152 downregulated miRNAs were detected in PMICF, while periodontitis patients had 333 upregulated miRNAs and 318 downregulated miRNAs. MiR-544a, miR-1245b-3p, miR-1825, miR-4291, miR-3689e, and miR-4477a were chosen randomly for further examination. qRT-PCR examination confirmed that the expression levels of miR-1245b-3p and miR-4291 were higher in PMSII than in H samples and that the expression levels of miR-1825 were higher in PMSII than in P samples. However, contrary to the NGS results, qRT-PCR analysis showed decreased expression of miR544a in PMSII. MiR3689e and miR4477a expression did not differ significantly among all samples. According to GO and KEGG pathway analyses of miR-1825, miR-4291, and miR-1245b-3p high enrichment of target genes involved in the PI3K-AKT signalling pathway was observed. CONCLUSIONS: The NGS analysis of normal and orthodontic PMICF/CGF showed different miRNA profiles, which may lay the foundation for future research on the molecular mechanism of PMSII. miR-4291, miR-1245b-3p and miR-1825 may be used as diagnostic markers and potential therapeutic targets for PMSII.

Genetic and molecular features for hepadnavirus and plague infections in the Himalayan marmot.

The Himalayan marmot (Marmota himalayana), a natural host and transmitter of plague, is also susceptible to the hepadnavirus infection. To reveal the genetic basis of the hepadnavirus susceptibility and the immune response to plague, we systematically characterized the features of immune genes in Himalayan marmot with those of human and mouse. We found that the entire major histocompatibility complex region and the hepatitis B virus pathway genes of the Himalayan marmot were conserved with those of humans. A Trim (tripartite motif) gene cluster involved in immune response and antiviral activity displays dynamic evolution, which is reflected by the duplication of Trim5 and the absence of Trim22 and Trim34. Three key regions of Ntcp, which is critical for hepatitis B virus entry, had high identity among seven species of Marmota. Moreover, we observed a severe alveolar hemorrhage, inflammatory infiltrate in the infected lungs and livers from Himalayan marmots after infection of EV76, a live attenuated Yersinia pestis strain. Lots of immune genes were remarkably up-regulated, which several hub genes Il2rγ, Tra29, and Nlrp7 are placed at the center of the gene network. These findings suggest that Himalayan marmot is a potential animal model for study on the hepadnavirus and plague infection.

Direct detection from clinical sputum samples to differentiate live and dead Mycobacterium Tuberculosis.

BACKGROUND: In this study, we aimed to optimize the condition of propidium monoazide (PMA) treatment for direct detection of Mycobacterium tuberculosis (MTB) from clinical specimens. METHODS: The light exposure time, dark incubation time, bacterial load, and PMA concentration were varied to determine the optimal condition of PMA treatment. RESULTS: Overall, the maximum ΔCq value was observed in the group receiving a light exposure time of 20 minutes, which was significantly higher than the others (P < 0.05). The prolongation of dark incubation time seemed more likely to result in greater ΔCq value, and the ΔCq values were 2.0, 4.1, 6.5, 10.1, and 12.7 cycles under dark incubation time of 10, 20, 40, 60, and 120 minutes, respectively. Alternatively, the 4+ samples exhibited favorable detection results at the application of 104 -fold dilution by PMA assay with Cq values higher than 35 cycles. Further evaluation revealed that the PMA assay showed an accordance rate of 98.0% (98/100) among clinical sputa. CONCLUSIONS: we develop an acceptable method to directly identify the live bacteria from sputum samples. Our data demonstrate that the dark incubation plays a crucial role in the efficacy of PMA treatment for MTB.

Knowledge, attitudes, and practice toward tuberculosis in high school students in Qingdao, China.

INTRODUCTION: The purpose of this study is to assess the levels of knowledge, attitude, and practice (KAP) related to TB, and to analyze the differences among various demographic groups. METHODOLOGY: A total of 621 students enrolled in Qingdao High School, coming from high TB burden settings. The cross-sectional study was conducted from May to July of 2022. Participants completed an online questionnaire. Differences in knowledge and practice based on participant characteristics were analyzed using the Wilcoxon rank test and Kruskal-Wallis rank test. Group differences were assessed using a rank-based analysis of variance. RESULTS: The mean percentage of correct answers for TB knowledge and practice was 82.09% and 83.25%, respectively. Grade Three students showed higher knowledge and practice scores than Grade One or Grade Two students (t = -3.9935, p = 0.0002, t = 3.4537, p = 0.0018. 8.58 vs 7.94, 8.58 vs 8.23. t = 3.4562, p = 0.0018, t = -2.8688, p = 0.0128. 1.78 vs 1.61, 1.78 vs 1.64). A significant majority (78.42%) of students expressed fear of being affected by TB. 49.28% of the students would support and help TB patients. 88.08% of participants had heard of TB, with 72.94% learning about it at school, mainly through visual aids like posters. Information was predominantly obtained from online sources (websites, microblogs, WeChat, etc.). CONCLUSIONS: It is recommended to develop a TB curriculum for lower-grade students to enhance awareness of TB prevention through various means, including the internet and social media.

Transmission of tuberculosis in an incarcerated population during the subclinical period: A cross-sectional study in Qingdao, China.

Objectives: As a closed gathering place, prison is the cradle of tuberculosis (TB) outbreak. Therefore, the analysis of the prevalence rate and risk factors of latent tuberculosis infection (LTBI) in prison will be a necessary measure to intervene in the spread of tuberculosis. Methods: In this study, we consecutively recruited 506 adult prisoners in Qingdao to carry out this cross-sectional study. TB and LTBI were screened by IGRA, X-ray, X-pert, sputum smear and culture. Results: A total of 17 TB, 101 LTBI and 388 HC were identified, with an infection rate of 23.32% (118/506) and a TB incidence rate of 3282/100,000 population. Age, malnutrition and inmates living with TB prisoners were risk factors for LTBI. Additionally, most TB cases (70.59%, 12/17) were subclinical tuberculosis (STB), contributing significantly to TB transmission. Conclusion: Our results demonstrate that the transmission efficiency of asymptomatic patients is not essentially different from that of symptomatic patients, indicating that TB transmission occurs during the subclinical period. Our findings highlight the need to strengthen active case-finding strategies to increase TB case detection in this population.

Molecular characterization of the type I IFN receptor in two woodchuck species and detection of its expression in liver samples from woodchucks infected with woodchuck hepatitis virus (WHV).

Type I interferons (IFN-α/ß) serve as the first line of defense against viral infection and share the same type I IFN receptor (IFNAR) complex, which is composed of IFNAR1 and -2. The Eastern woodchuck (Marmota monax) and Chinese woodchuck (Marmota himalayana) are suitable for studying hepatitis B virus (HBV) infection. Here, the complete or partial sequences of the IFNARs of both species were obtained and analyzed. Small interference RNAs targeting wIFNAR1 and -2 specifically down-regulated the expression of wIFNAR1 and -2 and the IFN-stimulated gene MxA in a woodchuck cell line, respectively. IFNAR2 was significantly up-regulated in primary woodchuck hepatocytes stimulated with IFN-α or -γ. The expression of woodchuck IFNAR1 and -2 was decreased in woodchucks chronically infected with woodchuck hepatitis virus (WHV). These results are essential for studying type I IFN-related innate immunity and therapy in hepadnaviral infection in the woodchuck model.

Double-grating displacement structure for improving the light extraction efficiency of LEDs.

To improve the light extraction efficiency of light-emitting diodes (LEDs), grating patterns were etched on GaN and silver film surfaces. The grating-patterned surface etching enabled the establishment of an LED model with a double-grating displacement structure that is based on the surface plasmon resonance principle. A numerical simulation was conducted using the finite difference time domain method. The influence of different grating periods for GaN surface and silver film thickness on light extraction efficiency was analyzed. The light extraction efficiency of LEDs was highest when the grating period satisfied grating coupling conditions. The wavelength of the highest value was also close to the light wavelength of the medium. The plasmon resonance frequencies on both sides of the silver film were affected by silver film thickness. With increasing film thickness, plasmon resonance frequency tended toward the same value and light extraction efficiency reached its maximum. When the grating period for the GaN surface was 365 nm and the silver film thickness was 390 nm, light extraction efficiency reached a maximum of 55%.

Establishing a new animal model for hepadnaviral infection: susceptibility of Chinese Marmota-species to woodchuck hepatitis virus infection.

Hepatitis B virus infection (HBV) is a major medical problem in China. The lack of a suitable infection model in China is recognized as an obstacle for research on HBV in China. Chinese Marmota-species is phylogenetically closely related to Marmota monax, thus, it might be suitable to serve as an animal model for HBV infection. Therefore, we attempted to prove the claim about the existence of woodchuck hepatitis virus (WHV)-like viruses in Chinese Marmota-species and to determine the susceptibility of these species to experimental WHV infection. In the present study, 653 sera from three Chinese Marmota-species, Marmota himalayana, Marmota baibacina and Marmota bobak, were screened for WHV-like viruses by serological and molecular assays. The susceptibility to WHV of three species was investigated by experimental infection and monitored by testing of anti-WHc and WHsAg by ELISA, detection of WHV DNA by PCR, and detection of WHV replication intermediates and antigens in liver samples. No evidence for the existence of a genetically closely related virus to WHV in three Chinese Marmota-species was found by serological assays and PCR. M. himalayana was susceptible to WHV infection as inoculated animals became positive for anti-WHc, WHsAg and WHV DNA. Further, WHV replication intermediates and proteins were detected in liver samples. In contrast, M. baibacina remained negative for tested virological parameters. M. bobak species showed a limited susceptibility to WHV. Our data do not support early reports about WHV-like viruses in China. M. himalayana is suitable for the establishment of a model for hepadnaviral infection.

Frequency and Temperature-Dependent Space Charge Characteristics of a Solid Polymer under Unipolar Electrical Stresses of Different Waveforms.

In this paper, we studied the space charge phenomena of a solid polymer under thermal and electrical stresses with different frequencies and waveforms. By analyzing the parameter selection method of a protection capacitor and resistor, the newly built pulsed electro-acoustic (PEA) system can be used for special electrical stresses under 500 Hz, based on which the charge phenomena are studied in detail under positive and negative DC and half-wave sine and rectangular wave voltages. Experimental results show that the charge accumulated in the polyimide polymer under DC conditions mainly comes from the grounded electrode side, and the amount of charge accumulated with electric field distortion becomes larger in a high-temperature environment. At room temperature, positive charges tend to accumulate in low-frequency conditions under positive rectangular wave voltages, while they easily appear under high-frequency situations of negative ones. In contrast, the maximum electric field distortion and charge accumulation under both half-wave sine voltages occur at 10 Hz. When the measurement temperature increases, the accumulated positive charge decreases, with a more negative charge appearing under rectangular wave voltages, while a more positive charge accumulates at different frequencies of half-wave sine voltages. Therefore, our study of the charge characteristics under different voltage and temperature conditions can provide a reference for applications in the corresponding environments.

[Study on experiment of fluorescence spectra detection of organic pesticides in soil].

The fluorescence characteristics of carbamate pesticide, namely carbaryl, was studied based on the basic theory that organic molecules can emit fluorescence as they are excited by rays. Consequently, a fluorescence spectrograph was applied to conduct fluorescence spectrum experiments with standard solution of carbaryl and the hydrolyzed carbaryl, the fluorescence spectra were obtained under the condition of different concentration, and the relation between their fluorescence intensity and concentration was also analyzed. On the basis of this, using the soil as a medium, the fluorescence characteristics of carbaryl and the hydrolyzed carbaryl in the soil were researched as well. The experiment results show that carbaryl and the hydrolyzed carbaryl in the soil can also emit intensive fluorescence which is similar to that in solution as being excited by UV rays. The fluorescence spectra are located between 400 and 750 nm and they all have smooth spectrum forms and fine resolution, so the spectra are suitable for qualitative and quantitative analysis of carbaryl. As a result, it is feasible to carry out the detection and analysis of the concerned pesticides in soil directly or indirectly by fluorescence spectral analysis.

Feasibility and Performance of Loop-Mediated Isothermal Amplification Assay in the Diagnosis of Pulmonary Tuberculosis in Decentralized Settings in Eastern China.

Early diagnosis is essential for the control and prevention of tuberculosis (TB). The objective of this study was to investigate the feasibility and performance of loop-mediated isothermal amplification (LAMP) in the diagnosis of pulmonary TB in county-level microscopy centers in Qingdao, Eastern China. A total of 523 presumptive TB patients were consecutively recruited between July 2017 and April 2018, and 22 patients were excluded from the analysis. Of 102 culture-positive cases, TB-LAMP identified 91 cases, demonstrating a sensitivity of 89.2%. In comparison, the sensitivity of routine smear microscopy was 69.6% (71/102), which was significantly lower than that of TB-LAMP (P=0.001). In addition, TB-LAMP sensitivities in smear-positive and smear-negative samples were 98.6% and 67.7%, respectively. In conclusion, our data demonstrate that TB-LAMP outperforms conventional smear microscopy in TB diagnosis, which could be used as an alternative method for smear microscopy in resource-limited settings in China.

Hypoxic and Cold Adaptation Insights from the Himalayan Marmot Genome.

The Himalayan marmot (Marmota himalayana) is a hibernating mammal that inhabits the high-elevation regions of the Himalayan mountains. Here we present a draft genome of the Himalayan marmot, with a total assembly length of 2.47 Gb. Phylogenetic analyses showed that the Himalayan marmot diverged from the Mongolian marmot approximately 1.98 million years ago. Transcriptional changes during hibernation included genes responsible for fatty acid metabolism in liver and genes involved in complement and coagulation cascades and stem cell pluripotency pathways in brain. Two selective sweep genes, Slc25a14 and ψAamp, showed apparent genotyping differences between low- and high-altitude populations. As a processed pseudogene, ψAamp may be biologically active to influence the stability of Aamp through competitive microRNA binding. These findings shed light on the molecular and genetic basis underlying adaptation to extreme environments in the Himalayan marmot.

Effects of active and latent H. pylori infection coupled with chronic alcohol ingestion on cytokine profiles and markers of oxidative balance in men seropositive for H. pylori CagA Ab: An observational study.

This study aimed to explore the effects of active and latent Helicobacter pylori infection coupled with alcohol consumption on cytokine profiles and markers of oxidative balance in men seropositive for H. pylori CagA Ab.The 100 male subjects were divided into groups with active H. pylori infection and H. pylori CagA Ab coupled with chronic alcohol ingestion (group A, n = 38), latent H. pylori infection with H. pylori CagA Ab coupled with chronic alcohol ingestion (group B, n = 30), and latent H. pylori infection with H. pylori CagA Ab without chronic alcohol ingestion (group C, n = 32).No differences in serum levels of CRP, IL-10, ADP, E-selectin, MDA, or SOD were detected between the 3 groups or between any 2 groups (all P > .05). The serum IL-6 and TNF-α concentrations in groups A and B were significantly lower than those in group C (P = .004, P = .005, P = .009, and P = .023). However, there were no differences in serum IL-6 and TNF-α between group A and group B (all P > .05).In conclusion, active or latent H. pylori infection coupled with chronic alcohol ingestion may decrease certain cytokines, that is, IL-6 and TNF-α, in men with H. pylori CagA Ab seropositivity. However, there was no difference in the detected cytokine profile between active and latent H. pylori infection coupled with chronic alcohol ingestion, and no changes were detected in markers of oxidative balance in men with H. pylori CagA Ab.

[Study on the detection of organic pesticides by fluorescence spectra].

In the present paper the basic theory that organic molecules can emit fluorescence as they are excited by ultraviolet rays is described, the molecular structures of a few common pesticides, such as carbamate, benzoylurea and fungicide, are analyzed, and the mechanism of fluorescence generation is also ascertained. Consequently, the theoretic basis for further detection of pesticides by means of fluorescence methods is provided. Moreover a steady-state fluorescence spectrograph was applied to conduct fluorescence spectrum experiments with standard solutions of these pesticides, the fluorescence spectra were obtained, and their fluorescence characteristics were also analyzed. The results indicate that carbamate, benzoylurea and fungicide pesticides may emit strong fluorescence when excited by UV rays under the condition of a certain solvent, their fluorescence spectra are distinct, and the resolution is fine. As a result, it is feasible to carry out qualitative and the quantitative analysis of the concerned pesticides by fluorescence spectral analysis.

Involvement of microRNA-718, a new regulator of EGR3, in regulation of malignant phenotype of HCC cells.

OBJECTIVE: Hepatocellular carcinoma (HCC) is still one of the most common death-related malignancies worldwide. Because the way onset and progression are hidden most, HCC diagnoses are made at an advanced stage, when they are unsuitable for surgical resection. MicroRNAs are a class of small non-coding RNAs, participating in many aspects of cancers. In this study, we tried to establish the role of microRNA-718 (miR-718) in the malignant phenotype of HCC cells and its possible role in HCC diagnosis. METHODS: Here we first used a methylthiazolyldiphenyl-tetrazolium bromide (MTT) assay, Transwell migration and invasion assays, and colony formation assay to evaluate the impact of miR-718 on the malignant phenotypes of HCC cells. Then, we used bioinformatic methods to predict the target gene of miR-718 and used green fluorescence protein (GFP) reporter assay, Western blot, and quantitative real-time polymerase chain reaction (qRT-PCR) to validate the regulation relationship. Finally, we determined the role of the target gene in the HCC phenotype. RESULTS: We found that the expression of miR-718 was significantly reduced in various HCC cell lines and HCC tissues. Re-expression of miR-718 significantly reduced the cellular viability and colony formation ability as well as inhibited the migration and invasion abilities of HCC cell lines. Early growth response protein 3 (EGR3) is a direct target of miR-718 and is negatively regulated by miR-718. EGR3 could increase the viability and proliferation of HCC cells, and promot the migration and invasion of HCC cells. CONCLUSIONS: miR-718 acts as a tumor suppressive microRNA in HCC via regulating the expression of EGR3, which may provide a new diagnostic marker and treatment target for HCC.

Risk Factors Associated With Increased Carotid Intima-Media Thickness in a Male Population With Chronic Alcohol Consumption: A Prospective Observational Study.

Previous studies have reported a relationship between alcohol consumption and carotid intima-media thickness (CIMT). However, the exact associations between different severities of CIMT and dyslipidemia, dyslipoproteinemia, inflammatory immune markers, and oxidative markers associated with chronic alcohol consumption remain unknown. The aim of this study was to explore whether there are associations between different severities of CIMT and dyslipidemia, dyslipoproteinemia, inflammatory immune markers, and oxidative markers associated with chronic alcohol consumption. We enrolled 173 males with chronic alcohol consumption and categorized them into 2 groups: 104 chronic alcohol consumers with normal CIMT (group A) and 69 chronic alcohol consumers with increased CIMT (group B). Nonparametric statistics showed that age, body mass index (BMI), and serum TC, TG, Apo A1, and ApoB levels were significantly higher in group B than in group A (P = 0.002, 0.019, 0.021, 0.023, 0.001, and 0.001, respectively). Additionally, tumor necrosis factor alpha (TNFα) and HSP70 serum levels were significantly lower in group B than in group A (P = 0.023 and 0.017, respectively). A binary logistic regression analysis showed that age (OR: 1.077, 95% CI: 1.024-1.13, P = 0.004), ApoB (OR: 6.828, 95% CI: 1.506-30.956, P = 0.013), and TNF-α (OR: 0.999, 95% CI: 0.998-1.00) were independent risk factors associated with CIMT. The present study demonstrated that age, ApoB, and TNFα are independent risk factors associated with CIMT. Thus, older subjects with increased serum ApoB levels are more likely to present with increased CIMT, suggesting that age and ApoB promote such thickening and that TNFα downregulation might play a protective role against the progression of subclinical atherosclerosis in subjects with chronic alcohol consumption.

Influence of H. pylori CagA Coupled with Alcohol Consumption on Cytokine Profiles in Men.

The aim of this study was to evaluate the effect of Helicobacter pylori (H pylori) cytotoxin-associated gene A (CagA) coupled with chronic alcohol ingestion on cytokine profiles.A total of 215 male subjects were divided into the following 4 groups: 130 alcohol H pylori CagA-negative consumers (CagA-) (group A), 50 alcohol H pylori CagA-positive consumers (CagA+) (group B), 24 nonalcohol H pylori CagA-negative consumers (group C), and 11 nonalcohol H pylori CagA-positive consumers (group D). The serum CagA, C-reactive protein (CRP), interleukin (IL)-6, IL-10, E-selectin, adiponectin (ADP), and tumor necrosis factor-α (TNF-α) levels were measured through enzyme-linked immunosorbent assays (ELISAs).After adjusting for age and mean alcohol drinking history, a multivariable linear regression analysis revealed that the mean daily alcohol consumption, IL-6, TNF-α, and ADP levels were significantly increased with increases in the serum CagA concentrations (P = 0.008, P = 0.000, P = 0.000, and P = 0.006, respectively). The serum IL-6 and IL-10 levels of group A were significantly lower than those of group B (all P = 0.000). Furthermore, the serum IL-6 and IL-10 levels of groups A and C were significantly lower than those of group D (all P = 0.000), and the serum IL-6 and IL-10 levels of group C were significantly lower than those of group B (all P = 0.000). The serum ADP and E-selectin levels of groups B and D were significantly higher than those of group A (P = 0.000). The serum ADP levels of group B were significantly higher than those of group C (P = 0.000), and the serum ADP and E-selectin levels of group C were significantly lower than those of group D (P = 0.000 and P = 0.005, respectively). Finally, the serum TNF-α levels of groups B, C, and D were significantly higher than those of group A (all P = 0.000), and the serum TNF-α levels of group C were significantly higher than those of group D (P = 0.005).In conclusion, H pylori CagA may result in significantly higher levels of several inflammatory markers in both alcohol consumers and nonalcohol consumers. However, chronic alcohol ingestion coupled with H pylori CagA positivity does not result in significant changes in cytokine profiles.
