Objective:To identify risk factors associated with endoscopic atrophic progression of gastric mucosa after Helicobacter pylori ( HP) eradication and to develop a risk scoring system for establishing an individualized endoscopic follow-up strategy for patients with chronic gastritis. Methods:This retrospective cohort study included chronic gastritis patients with successful HP eradication at the Department of Gastroenterology, Beijing Friendship Hospital between January 2018 and October 2021. Demographic characteristics, endoscopic findings, and other clinical data were analyzed. Endoscopic outcomes of gastric mucosal atrophy before and after follow-up were compared to classify patients into progression and non-progression groups. Univariate and multivariate analyses were performed to identify independent risk factors for endoscopic atrophic progression. A risk scoring system was then constructed based on these factors. Results:A total of 218 patients with chronic gastritis were included, including 153 in the non-progression group and 65 in the progression group. Multivariate logistic regression analysis showed that gastric ulcer ( P=0.008, OR=4.24, 95% CI: 1.46-12.25), history of proton pump inhibitor use ( P=0.007, OR=4.06, 95% CI: 1.46-11.27), alcohol consumption ( P=0.002, OR=3.77, 95% CI: 1.64-8.67), high-salt diet ( P=0.008, OR=2.90, 95% CI: 1.32-6.41), and high red meat intake ( P=0.025, OR=2.33, 95% CI: 1.11-6.31) were independent risk factors for endoscopic atrophic progression after HP eradication. The predictive model based on these 5 factors demonstrated strong discriminative capacity, with an area under the receiver operating characteristic curve of 0.813 (95% CI: 0.755-0.876, P<0.001). The optimal cut-off value was 1.5 points, stratifying patients into low-risk (0-2 points) and high-risk (3-5 points) groups. Conclusion:Patients with chronic gastritis remain susceptible to progression even after successful HP eradication. Individualized endoscopic follow-up strategies should be considered based on patients' medical history, medication use, lifestyle, and dietary habits.

Objective:To analyze the electroencephalogram(EEG) average relative power spectrum in patients with unipolar and bipolar depression under the eyes-open and eyes-closed resting states.Methods:A total of 38 patients with unipolar depression (UD group), 48 patients with bipolar depression (BD group), and 43 healthy controls (HC group) were recruited from August 2022 to December 2023.The 64-channel EEG was recorded under eyes-open (EO) and eyes-closed (EC) resting states which alternated twice. The Mann-Whitney U test and Kruskal-Wallis H test were performed by SPSS 25.0 software. Results:There were no significant differences in the average relative power of delta and beta bands among the UD, BD and HC groups in all EO and EC states (all P>0.05). The average relative power of theta band in the three groups showed statistically significant differences in all EO and EC states ( H=7.852-12.583, all P<0.05). Further pairwise comparisons showed that in the first EO and EC stage, the average relative power of theta band of the UD and BD groups were significantly higher than that of the HC group (EO1: 0.18(0.17, 0.21), 0.19(0.16, 0.21), 0.16(0.14, 0.18), EC1: 0.15(0.13, 0.21), 0.15(0.13, 0.20), 0.13(0.10, 0.16); all P<0.05).In the second EO and EC stage, the average relative power of theta band of the BD group was significantly higher than that of the HC group (EO2: 0.18(0.15, 0.22), 0.16(0.14, 0.18), EC2: 0.15(0.13, 0.19), 0.13(0.11, 0.16); both P<0.05).There were statistically significant differences in the average relative power of alpha band among the three groups in the first EO and EC stage, as well as the second EC stage ( H=5.027-10.668, all P<0.05). Further pairwise comparisons showed that in the first EO stage, the average relative power of alpha band in the BD group was significantly higher than that in the UD group (0.20(0.16, 0.25), 0.14(0.11, 0.22), P=0.003), and in the following EC stages, the average relative power of alpha band in the UD group was significantly lower than that in the HC group (EC1: 0.40(0.33, 0.46), 0.51(0.40, 0.58), EC2: 0.41(0.35, 0.50), 0.48(0.43, 0.58); both P<0.05). Conclusion:At the initial stage of the resting state, both unipolar and bipolar depression patients demonstrate abnormal theta band activity under the eyes-open and eyes-closed states, while the alpha band activity under the eyes-open condition differs between the two groups of patients. These findings may provide potentially objective biomarkers to assist the diagnosis of unipolar and bipolar depression patients in clinical settings.

Objective:To assess the correlation and consistency between the cancer risk-oriented endoscopic Kimura-Takemoto classification and the operative link for gastritis assessment (OLGA) in risk stratification of gastric cancer in patients with chronic gastritis after Helicobacter pylori ( H. pylori) eradication. Methods:From January 1, 2018 to October 31, 2021, 97 patients with chronic gastritis who successfully underwent H. pylori eradication at Beijing Friendship Hospital affiliated to Capital Medical University were selected. During the follow-up period, all patients underwent standardized magnifying endoscopy to assess gastric mucosal atrophy with the Kimura-Takemoto classification, which was classified as no or mild atrophy, moderate atrophy, and severe atrophy. Additionally, according to the new Sydney staging system, endoscopic biopsies were conducted at 5 sites of the patients to classify into OLGA stages 0, Ⅰ, Ⅱ, Ⅲ, or Ⅳ. Spearman rank correlation analysis and Kappa consistency test were performed to evaluate the correlation and consistency between the 2 evaluation systems, respectively. Area under the curve (AUC) of the receiver operating characteristic curve was used to calculate the predictive ability of the grading of gastric mucosal atrophy under endoscopy in high-risk histological staging. Furthermore, multivariate logistic regression analysis was used to assess factors influencing the consistency of the 2 evaluation systems. Chi-square test or Fisher′s exact test were used for statistical analysis. Results:Longitudinal follow-up was completed in 97 cases, with a follow-up time of (37.38±13.18) months after H. pylori eradication. The proportion of OLGA stage Ⅲ to Ⅳ in patients with no or mild atrophy (21.7%, 10/46) was lower than that in patients with moderate and severe atrophy (63.0%, 29/46 and 5/5, respectively), and the differences were statistically significant( χ2=16.07 and 13.30, both P<0.001). However, there was no significant difference in distribution of OLGA staging between patients with moderate atrophy and patients with severe atrophy (all P>0.05). The consistency rate of high-risk assessment for gastric cancer between the 2 evaluation systems was 73.2% (71/97). The correlation between the Kimura-Takemoto classification and OLGA staging was moderate ( r=0.47, 95% confidence interval(95% CI) 0.30 to 0.61, P<0.001). The result of consistency test indicated that the consistency of the 2 evaluation systems was moderate, and the Kappa value was 0.46 (95% CI 0.29 to 0.64, P<0.001). For patients with chronic gastritis after H. pylori eradication, the sensitivity of Kimura-Takemoto classification of moderate to severe atrophy under endoscopy in identifying high-risk of OLGA stages was 77.21% (95% CI 62.16% to 88.53%), the specificity was 69.81% (95% CI 55.66% to 81.66%), and the AUC was 0.735 (95% CI 0.636 to 0.820, P<0.01). As the time after H. pylori eradication increased (post- H. pylori eradication less than 18, 18 to 36, and more than 36 months), the consistency of atrophy assessment between the Kimura-Takemoto classification and OLGA staging reduced (7/8, 84.4% (27/32), 64.9% (37/57), respectively), and the difference was statistically significant ( χ2=4.36, P=0.037). The result of multivariate logistic regression analysis revealed that the time after H. pylori eradication more than 36 months ( OR=3.443, 95% CI 1.117 to 10.614, P=0.031) and gastric ulcer ( OR=3.928, 95% CI 1.177 to 13.110, P=0.026) were independent factors influencing the consistency between the Kimura-Takemoto classification and OLGA staging. Conclusions:The endoscopic and histological changes of chronic gastritis after eradication of H. pylori are consistent. Within short period after H. pylori eradication (no more than 36 months), the sensitivity of high-risk classification under endoscopy is high and the specificity is moderate, which can predict high-risk histological staging to a certain degree.

OBJECTIVE To determine the prevalence of frontal recess cells variations in patients with frontal sinus associated headache according to the International Frontal Sinus Anatomy Classification(IFAC).METHODS A retrospective study was conducted on the CT scans of sinuses in patients with frontal sinus associated headache.We reviewed 46 patients with frontal sinus-related headache who had clinical symptoms and were relieved after nasal endoscopic surgery.The development of frontal recess cells in the frontal recess drainage area was analyzed,and the variation of middle meatus and sinus involvement were analyzed in the same time.The Anatomical variations and imaging characteristics of frontal recess cells development in patients with frontal sinus associated headache were analyzed.RESULTS A total of 92 sinus CT profiles were analyzed in 46 patients.The most common cells were agger nasi cell(ANC)(100%,92/92),followed by supra bulla cell(SBC)(78.3%,72/92),supra agger cell(SAC)(67.4%,62/92),supra bulla frontal cell(SBFC)(27.2%,25/92),supra agger frontal cell(SAFC)(20.7%,19/92),frontal septal cell(FSC)(8.7%,8/92)and supraorbital ethmoid cell(SOEC)(0%,0/92).In the conventional frontal sinus drainage area,SAFC(P=0.0108),SAC(P=0.0104)and SAFC(P=0.0088)in the IFAC classification were significantly associated with the occurrence of frontal sinus associated headache.At the same time,the middle concha bullosa also showed a significant correlation with the occurrence of frontal sinus associated headache in the lower segment of the frontal recess drainage channel(P=0.0390).CONCLUSION In the frontal recess drainage channel,the abnormal development of SAC,SAFC,SBFC and the middle concha bullosa are significantly correlated with frontal sinus associated headache.

OBJECTIVE To test whether there are some differences among chronic rhinitis,chronic rhinosinusitis patients with nasal polyps(CRSsNP)and without nasal polyps(CRSsNP)in symptom severity,health-related quality-of-life impairment,and objective inflammatory factors.METHODS A total of 154 consecutive patients who had been treated at the Otolaryngology Department of Beijing Tongren Hospital from January 2017 to December 2018 were recruited in this study.The patients aged 18-70 years,with 106 males and 48 females.All patients performed endoscopic examination,nasal exhaled nitric oxide(nNO),skin prick test(SPT),sinus CT scan,complete blood count,and fulfilled the visual analogue scale(VAS)self-assessment of nasal symptoms and the SNOT-22 questionnaire under the guidance of the physician.According to the inclusion criteria,A total of 43 patients with CR,58 patients with CRSsNP and 53 patients with CRSwNP were enrolled in our study.RESULTS The total SNOT-22 score in CRSsNP group was significantly lower than that in CR and CRSwNP groups(30.0±19.4 vs.41.1±21.9,30.0±19.4 vs.40.9±18.7,P<0.05),and there was no significant difference between CR group and CRSwNP group.The average scores of nasal symptoms and extranasal symptoms in CRSwNP group were the highest;the scores in CRSsNP group were lower.The impact of CR patients on sleep damage was significantly higher than that in CRSsNP patients(9.9±6.2 vs.5.1±5.3,P<0.05),and there was no significant difference between CR group and CRSwNP group(9.9±6.2 vs.7.1±5.7,P>0.05).When patients suffered with positive SPT,there was no statistical difference in symptom scores and SNOT-22 scores between CR,CRSsNP,and CRSwNP;but with negative SPT,there was a significant statistical difference in both symptom scores and SNOT-22 scores among the three groups.CONCLUSION CR,CRSsNP and CRSwNP have a significant impact on quality of life,respectively.In terms of symptom scores and quality of life scores,the CR group and CRSwNP group are similar and the scores are higher than that of the CRSsNP group.However,the objective inflammation factors are not consistent with the subjective symptom scores and quality of life scores.

Objective:To assess the effects of nutritional interventions combined with Traditional Chinese Med-icine(TCM)physical dialectics on the development of gestational diabetes mellitus(GDM),dietary status during pregnancy,and maternal and infant outcomes in high-risk pregnant women in early pregnancy.Methods:298 high-risk pregnant women with GDM in early pregnancy(gestational week≤14 weeks)registered in the Obstet-rics Department of Urumqi Maternal and Child Health Hospital from 1st December 2022 to 30th March 2023 were selected as the study subjects and randomly divided into the intervention group(149 cases)and the control group(149 cases).During 14 to 23+6 weeks of pregnancy,TCM constitution nutritional intervention was carried out for pregnant women in the intervention group,and routine guidance and healthy dietary education was carried out in the control group.The incidence of GDM in the two groups was compared at 24-28 weeks of pregnancy,and the relationship between early pregnancy nutritional intervention combined with TCM constitution and the risk of GDM was analysed in subgroups using logistic regression and likelihood ratio test.The dietary situation,biochemical in-dexes and delivery outcomes after the intervention were compared at 32-36 weeks of pregnancy.Results:①The incidence of GDM in the intervention group was significantly lower than that in the control group(14.09％vs.23.49％,P＜0.05).The effect of the TCM constitution based nutritional intervention on the risk probability of GDM was statistically significant only among pregnant women with different ranges of gestational weight gain(GWG)(P=0.018).Among them,pregnant women with GWG lower than the recommended range had a reduced risk of GDM after intervention(OR 0.27,95％Cl 0.10-0.68,P=0.008).② After intervention,the evaluation index of di-etary balance index of pregnant women in the intervention group was better than that of the control group(P＜0.05),and the intake of cereals and potatoes,vegetables,and water of pregnant women in late pregnancy in the intervention group was higher than that of the control group(P＜0.05).③The levels of triglycerides,total choles-terol,low-density lipoprotein,glycated haemoglobin,uric acid and creatinine of pregnant women in the intervention group were lower than those of the control group in late pregnancy(P＜0.05).GWG,gestational age at delivery,the rate of low-birth-weight,and the neonatal 1-minute Apgar scores were all better than those of the control group(P＜0.05.Conclusions:Nutritional interventions in early pregnancy combined with TCM constitution can sig-nificantly reduce the incidence of GDM in high-risk pregnant women and the chances of low-birth-weight babies.Obstetrics outpatient clinics can actively develop extensive collaboration with TCM and clinical nutrition depart-ments to reduce adverse pregnancy outcomes for both mother and fetus.
