Objective:To study reflux characteristics of patients with endoscopic negative heartburn and their manifestation under probe-based confocal laser endoscopy (pCLE) based on the Rome Ⅳ standard.Methods:Thirty-six endoscopic negative outpatients with typical heartburn at the Department of Gastroenterology of the Second Affiliated Hospital of Baotou Medical College from September 2020 to March 2021 were included, and underwent 24-hour multichannel intraluminal impedance-pH monitor and pCLE. According to Rome Ⅳ diagnostic process, patients were divided into non-erosive reflux disease (NERD) group ( n=16), reflux hypersensitivity (RH) group ( n=8) and functional heartburn (FH) group ( n=12). The Gerd-Q scale score, 24-hour pH monitoring results and microstructure changes under pCLE were compared among the three groups. Results:There was no significant difference in the total score, positive symptom score, negative symptom score or positive influence score of Gerd-Q scale among the three groups ( P>0.05). DeMeester score [28.45 (20.08, 34.53)] and acid reflux times (24.88±9.05) in the NERD group were significantly higher than those in the RH group [7.30 (3.90, 11.38), P<0.001; 13.63±5.76, P=0.003] and FH group [6.90 (4.80, 9.73), P<0.001; 7.42±8.32, P<0.001]. But there was no significant difference between the RH group and the FH group ( P>0.05). The diameter of intra-papillary capillary loop (IPCL) (18.68±2.12 μm) and dilation of intercellular space (3.95±0.97 μm) in the NERD group were significantly higher than those in the RH group (13.91±1.99 μm, P<0.001; 2.97±0.55 μm, P=0.006) and FH group (13.83±2.00 μm, P<0.001; 2.31±0.54 μm, P<0.001), but there was no significant difference between the RH group and the FH group ( P>0.05). The number of IPCL in the NERD group, RH group and FH group were 2.0 (1.00, 2.75), 2.0 (1.00, 2.75) and 1.5 (1.00, 2.00), respectively with no significant difference ( P=0.697). Conclusion:Gerd-Q scale is not suitable for differential diagnosis of patients with endoscopic negative heartburn. Compared with functional esophageal diseases (RH and FH), acid reflux and mucosal microstructure changes are of more important pathogenic significance in NERD.

Background:
and Purpose The relationships among interleukin (IL)-10 levels, anxiety, and cognitive status after stroke remain controversial. We aimed to determine the associations of serum IL-10 levels with poststroke anxiety (PSA) and poststroke cognitive impairment (PSCI).
Methods:
We recruited 350 patients with stroke, of whom only 151 completed a 1-month follow-up assessment. The Mini Mental State Examination (MMSE) and Hamilton Anxiety Scale (HAMA) were used to assess the cognitive status and anxiety, respectively. Serum IL-10 levels were measured within 24 hours of admission.
Results:
IL-10 levels were significantly lower in the PSA group than in the non-PSA group, and they were negatively associated with HAMA scores (r=-0.371, p<0.001). After adjusting for all potential confounders, IL-10 levels remained an independent predictor of PSA (odds ratio=0.471, 95% confidence interval=0.237–0.936, p=0.032). IL-10 levels were strongly correlated with behavior during interviews, psychic anxiety, and somatic anxiety. Patients without PSCI had higher IL-10 levels were higher in non-PSCI patients than in PSCI patients, and they were positively associated with MMSE scores in the bivariate correlation analysis (r=0.169, p=0.038), and also with memory capacity, naming ability, and copying capacity.However, IL-10 did not predict PSCI in the univariable or multivariable logistic regression.
Conclusions
Low IL-10 levels were associated with increased risks of PSA and PSCI at a 1-month follow-up after stroke. Serum IL-10 levels may therefore be helpful in predicting PSA.

The value of 24 - hour multichannel intraluminal impedance - pH (24 h MII - pH) monitoring is still unknown in most patients with gastroesophageal reflux disease (GERD), and the value of mean nocturnal baseline impedance (MNBI) in the diagnosis of GERD remains controversial. Aims: To analyze the characteristics of esophageal MNBI in GERD patients, and to investigate the diagnostic value of MNBI for GERD. Methods: The clinical data of 111 patients suspected of GERD and monitored for 24 h MII-pH from May 2019 to December 2021 at the Second Affiliated Hospital of Baotou Medical College were retrospectively analyzed. According to DeMeester standard, patients were divided into non - GERD group and GERD group. Reflux parameters and MNBI of each channel between the two groups were compared. The correlation between distal and proximal esophageal MNBI and reflux parameters were analyzed. ROC curve was used to evaluate the sensitivity and specificity of MNBI for GERD. Results: Compared with non-GERD patients, the acid exposure time (AET), DeMeester score, total reflux times, acid reflux times and non-acid reflux times in GERD group were increased, the differences were statistically significant (P<0.01). MNBI at 3 cm, 5 cm and 7 cm above the dentate line and distal MNBI in the GERD group were decreased, the differences were statistically significant (P<0.01). Spearman correlation analysis showed that distal MNBI was negatively correlated with AET, DeMeester score, acid reflux times and weak acid reflux times (P<0.05). There were significant negative correlations between proximal MNBI and AET, DeMeester score and weak acid reflux times (P<0.05). ROC curve analysis showed that AUC of distal MNBI for the diagnosis of GERD was 0.72 (95% CI: 0.66-0.81, P<0.01), when the cut-off value was 1 191.42 Ω, the sensitivity and specificity of distal MNBI for diagnosis of GERD were 82.9% and 53.9%, respectively. Conclusions: Distal esophageal MNBI has good diagnostic significance for GERD patients, and can be used as a new impedance index for the auxiliary diagnosis of GERD.

Objective:To investigate the alteration of m6A demethylase AlkB homolog 5 (ALKBH5) expression and its impact on form-deprivation myopia (FDM) retina in guinea pigs.Methods:Thirty normal SPF grade 3-week-old tricolor guinea pigs were randomly divided into normal control group and experimental group, with 15 in each group.In the experimental group, the right eyes were covered as FDM group and the left eyes uncovered were set as self-control group.Ocular biometry was performed at one-week intervals from baseline to week 4 of the experiment.Spherical equivalent was detected by streak retinoscopy and axial length was measured by A-scan ultrasonography.Animals were sacrificed after 4 weeks of modeling.The distribution and expression of ALKBH5 protein in the guinea pig retina was detected by immunohistochemical and immunofluorescence staining.Expression of ALKBH5 mRNA and protein in guinea pig retina was detected by real-time fluorescence quantitative PCR and Western blot, respectively.The use of animals in ophthalmic and vision research followed the tenets of Animal Research in Vision and Ophthalmology, and the study was approved by the Ethics Committee of North Sichuan Medical College (No.2023087).Results:At weeks 2, 3, and 4 after myopia induction, diopters and axial lengths were significantly higher in the FDM group than in the normal control group and the self-control group (all at P<0.001). Immunohistochemistry and immunofluorescence assays showed that ALKBH5 protein was expressed in the retinal nerve fiber layer, rod/cone photoreceptor cells, and retinal pigment epithelium (RPE) layer, and was highly expressed in the retinal nerve fiber layer and RPE layer.The relative ALKBH5 immunofluorescence intensity in the normal control group, self-control group and FDM group was 1.000±0.204, 0.874±0.076 and 0.571±0.053, respectively, which was lower in the FDM group than in the normal control and self-control groups, showing statistically significant differences ( t=4.069, P=0.006; t=5.176, P=0.014). After 4 weeks of modeling, ALKBH5 mRNA and protein expressions were significantly lower in FDM group than in normal control and self-control groups (both at P<0.01). Conclusions:The expression of m6A demethylase ALKBH5 is decreased in the retina of FDM guinea pigs, suggesting that ALKBH5 and related m6A methylation modification may be involved in the development and progression of myopia.

Nodular gastritis is directly related to Helicobacter pylori (Hp) infection. Refractory Hp infection has significant impact on the treatment efficacy and prognosis of nodular gastritis. Aims: To analyze the spheroidization and antibiotic resistance of refractory Hp and PPI drug metabolic enzyme CYP2C19 gene polymorphism in patients with nodular gastritis, so as to promote the eradication rate of refractory Hp infection in patients with nodular gastritis. Methods: Refractory Hp infection patients with nodular gastritis from Oct. 2019 to Nov. 2020 at the Second Affiliated Hospital of Baotou Medical College were enrolled. Hp strains were cultured in microaerophilic environment. Immunohistochemistry was used to detect Hp spheroidization. Mutation sites of antibiotic resistance genes and host CYP2C19 gene polymorphism were detected by PCR. According to the results of genetic testing, individualized therapy was given and follow up was performed, the eradication rate of intention-to-treat was calculated. Results: A total of 42 patients with refractory Hp nodular gastritis were enrolled. Among them, lymphocyte accumulation was found in 33.3% patients. Hp spheroidization was found in 2 patients, and the spheroidization rates were 20% and 10%, respectively. There were 25 intensive metabolizer, 15 intermediate metabolizer and 2 poor metabolizer of CYP2C19. Antibiotic resistance gene detection showed that the drug resistance rate of amoxicillin, clarithromycin, levofloxacin, furazolidone, tetracycline, metronidazole were 4.8%, 38.1%, 35.7%, 47.6%, 42.9% and 61.9%, respectively. Twenty-two (52.4%) of the patients developed resistance to 3 or more antibiotics. The total eradication rate of intention-to-treat was 83.3%, of which high-dose dual therapy was 88.9%. Conclusions: Multi-antibiotic resistance and CYP2C19 may be the main reason for the failure of eradication of refractory Hp in nodular gastritis. Hp spheroidization has little effect on the efficacy of eradication therapy. The amoxicillin resistance rate is still significantly lower than that of other antibiotics, and high-dose dual therapy is a better option.
