Objective:This study identifies independent predictive indicators to distinguish autoimmune gastritis from Helicobacter pylori ( H. pylori)-induced atrophic gastritis and validates their diagnostic performance to compare laboratory indicators of autoimmune gastritis and H. pylori-induced atrophic gastritis. Methods:A retrospective comparison of laboratory examination indicators was conducted for chronic atrophic gastritis patients with involvement of the gastric fundus and corpus, who were followed up at the Department of Gastroenterology, Xijing Hospital, from January 2014 to September 2024. Receiver operating characteristic (ROC) curves were utilized to determine the optimal cutoff points and corresponding diagnostic thresholds. In addition, multivariate logistic regression analysis was conducted to identify independent predictive indicators for autoimmune gastritis, with further assessment in a validation cohort.Results:A total of 139 patients with autoimmune gastritis and 209 patients with H. pylori-induced atrophic gastritis were included. Pepsinogen (PG) Ⅰ levels and the PG Ⅰ/PG Ⅱ ratio in patients with autoimmune gastritis were significantly lower than in those with H. pylori-induced atrophic gastritis [11.0 (4.8, 22.5) vs. 41.8 (32.2, 59.9) μg/L, U=722.00, P<0.001; 1.24 (0.75, 3.54) vs. 5.76 (4.31, 7.12), U=817.00, P<0.001], while gastrin levels were significantly higher [375 (84, 738) vs. 49 (35, 81) ng/L, U=378.00, P<0.001]. PG Ⅰ was identified as an independent predictive variable, with an area under the ROC curve of 0.847 (95% CI 0.791-0.904), sensitivity of 77.6%, specificity of 91.8%, positive predictive value of 80.5%, and negative predictive value of 90.5%. Conclusions:Significant differences in laboratory indicators were observed between autoimmune gastritis and H. pylori-induced atrophic gastritis in chronic atrophic gastritis involving gastric fundus and corpus. Besides, PG Ⅰ demonstrated good diagnostic performance in identifying autoimmune gastritis and can effectively differentiate between different types of atrophic gastritis.

Objective:To explore the learning curve of primary urologists mastering Holmium laser enucleation of the prostate for the treatment of large volume benign prostatic hyperplasia (BPH).Methods:The clinical data of 92 patients with larger volume BPH who received HoLEP performed by a urologist in Beijing Friendship Hospital Pinggu Campus, Capital Medical University were retrospectively reviewed. 92 patients were divided into group A (1-23 cases, n=23), group B (24-46 cases, n=23), group C (47-69 cases, n=23), and group D (70-92 cases, n=23) based on the sequence of surgery. The clinical characteristics, including prostate volume, operation time, enucleation efficiency, indwelling catheter time, decrease value of hemoglobin, intraoperative blood transfusion, perioperative complications, and international prostate symptom score (IPSS), quality of life (QOL) score, Qmax, and postvoid residual urine (PVR) at 3 months postoperatively were compared between the four groups. Measurement data were expressed as mean ± standard deviation ( ± s), one-way analysis of variance was used for comparisons among multiple groups, and t-test was used for comparisons between two groups. Count data were expressed as the cases and percentage, and the Chi-square test was used for comparison between groups. Results:There were significant differences among the four groups in terms of operation time [(94.43±8.26) min, (86.39±5.89) min, (70.70±5.64) min, (64.70±4.23) min, P=0.001], enucleation efficiency [(0.90±0.08) mL/min, (1.01±0.07) mL/min, (1.23±0.12) mL/min, (1.34±0.12) mL/min, P=0.001], decrease value of hemoglobin [(25.98±1.39) g/L, (23.27±1.49) g/L, (20.03±1.07) g/L, (18.49±0.96) g/L, P=0.001] and indwelling catheter time [(5.91±1.54) d, (5.35±1.27) d, (3.39±0.72) d, (3.04±0.64) d, P=0.001]. Compared with group C and group D, the operation time was longer, the enucleation efficiency was lower, the decrease value of hemoglobin before and after the operation was higher, and the indwelling catheter time was longer, the above differences were all statistically significant ( P<0.05). However, there was no statistically significant difference between group A and group B, or group C and group D ( P>0.05). Among the 92 patients, only 3 patients received blood transfusion during operation, including 2 patients in group A and 1 patient in group B. 2 patients underwent surgical complications during the perioperative period. Among them, 1 patient suffered bladder wall injury due to improper operation of the tissue pulverizer in group A, and 1 patient developed prostatic capsule perforation in group B. Furthermore, after 56 cases of operation, a primary urologist can perform HoLEP surgery quickly and safely. Conclusion:The learning curve of a primary urologist mastering HoLEP for larger volume (≥ 80 mL) BPH was 56 procedures, and the operation efficiency and safety were significantly improved.

Objective:To evaluate the association between septic shock and tracheal injury in the intensive care unit (ICU) patients with invasive ventilation.Methods:This was a prospective single-centre cohort study. Patients who underwent invasive mechanical ventilation at the Department of Anesthesia Critical Care Medicine of the Second Hospital of Hebei Medical University from May 31, 2020 to March 5, 2022 were selected. The general characteristics of patients, reasons for ICU admission, vital signs, laboratory test results, Acute Physiology and Chronic Health Evaluation Ⅱ scores, Charlson Comorbidity Index, size of endotracheal tube, presence or absence of septic shock, oxygenation index, duration of intubation, consumption of norepinephrine and epinephrine, and tracheal injury scores at the time of extubation were recorded. Univariate linear regression analysis was used to identify the risk factors for tracheal injury, followed by adjustment using multivariate linear regression analysis.Results:Ninety-seven patients were ultimately included, and the average age was (56.6±16.5) yr, with 64.9% being male. The results of adjusted linear regression showed that septic shock was associated with tracheal injury scores ( β=2.99, 95% confidence interval 0.70-5.29). Subgroup analysis revealed a stronger correlation with a duration of intubation≥8 days ( P=0.013). Conclusions:Patients with septic shock exhibit significantly higher tracheal injury scores compared with those without septic shock, suggesting that septic shock may serve as an independent risk factor for tracheal injury.

OBJECTIVES:
Shelter hospital was an alternative way to provide large-scale medical isolation and treatment for people with mild coronavirus disease 2019 (COVID-19). Due to various reasons, patients admitted to the large shelter hospital was reported high level of psychological distress, so did the healthcare workers. This study aims to introduce a comprehensive and multifaceted psychosocial crisis intervention model.
METHODS:
The psychosocial crisis intervention model was provided to 200 patients and 240 healthcare workers in Wuhan Wuchang shelter hospital. Patient volunteers and organized peer support, client-centered culturally sensitive supportive care, timely delivery of scientific information about COVID-19 and its complications, mental health knowledge acquisition of non-psychiatric healthcare workers, group activities, counseling and education, virtualization of psychological intervention, consultation and liaison were exhibited respectively in the model. Pre-service survey was done in 38 patients and 49 healthcare workers using the Generalized Anxiety Disorder 7-item (GAD-7) scale, the Patient Health Questionnaire 2-item (PHQ-2) scale, and the Primary Care PTSD screen for the Diagnostic and Statistical Manual of Mental Disorders, 5th edition (PC-PTSD-5). Forty-eight healthcare workers gave feedback after the intervention.
RESULTS:
The psychosocial crisis intervention model was successfully implemented by 10 mental health professionals and was well-accepted by both patients and healthcare workers in the shelter hospital. In pre-service survey, 15.8% of 38 patients were with anxiety, 55.3% were with stress, and 15.8% were with depression; 16.3% of 49 healthcare workers were with anxiety, 26.5% were with stress, and 22.4% were with depression. In post-service survey, 62.5% of 48 healthcare workers thought it was very practical, 37.5% thought more practical; 37.5% of them thought it was very helpful to relief anxiety and insomnia, and 27.1% thought much helpful; 37.5% of them thought it was very helpful to recognize patients with anxiety and insomnia, and 29.2% thought much helpful; 35.4% of them thought it was very helpful to deal with patients' anxiety and insomnia, and 37.5% thought much helpful.
CONCLUSIONS
Psychological crisis intervention is feasible, acceptable, and associated with positive outcomes. Future tastings of this model in larger population and different settings are warranted.

Papillary thyroid carcinoma is one of the most common thyroid cancer subtypes. Although papillary thyroid carcinoma can be treated effectively with excision, microwave ablation, radioactive iodine and hormone replacement therapy, these ways are inefficient in reducing its morbidity, mortality and recurrence rates. Therefore, it is very important to seek the molecular mechanism of the occurrence and development of papillary thyroid carcinoma, to provide effectively early diagnosis, accurate treatment and better long-term prognosis for papillary thyroid carcinoma patients. This paper summarizes the molecular regulatory mechanisms of non-coding RNAs and their related signaling pathways in the occurrence and development of papillary thyroid carcinoma, in order to provide evidence for continued research of biomarkers for papillary thyroid carcinoma.
