Objective To explore the psychological experiences of operating room nurses participating in organ transplant surgeries, providing a basis for medical institutions to develop targeted psychological support programs. Methods Using a phenomenological research method, semi-structured, in-depth, face-to-face interviews were conducted from January to March 2026 with 17 operating room nurses who had participated in organ transplant surgeries at a tertiary hospital in Shanghai. Interviews were recorded, and observations were made. The interview data were analyzed, summarized, and themes were refined using Colaizzi’s seven-step analysis method. Results The psychological experiences of operating room nurses participating in organ transplant surgeries were identified as 5 main themes and 14 sub-themes: emotional impact and empathy load (shock and grief confronting life and death, deep empathy for patients and families, awe and gratitude towards organ donors); pressure experience and physical-mental exhaustion (urgency under time pressure, load of operational precision requirements, excessive consumption of physical and mental resources); cognitive appraisal and meaning construction (reappraisal of professional value, deep reflection on the meaning of life, positioning and identification of one’s role); coping strategies and adjustment process (active learning and experiential reflection, self-emotional regulation and social support); growth experience and psychological transformation (enhancement of psychological resilience, establishment of professional confidence, deepening of professional mission). Conclusions Operating room nurses undergo complex and profound psychological experiences while participating in organ transplant surgeries, enduring strong emotional impact and physical-mental stress while also achieving psychological growth and deepening professional identity through practice. Nursing managers should pay attention to the mental health of this group and construct a multi-level support system to promote their physical and psychological well-being.

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 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 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.

Objective To investigate the value of multiparametric CT features for predicting the risk classification of gastric stro-mal tumor(GST).Methods The clinical data from 139 patients with GST were retrospectively collected.According to the patho-logical risk results,the patients were divided into two groups:a low-risk GST group(including very low-and low-risk)with 75 patients and a high-risk GST group(including medium and high-risk)with 64 patients.The CT features between low-risk GST group and high-risk GST group were compared using chi-squared test or t-test.The risk factors of high-risk GST were identified by univariate analysis.The prediction models were built by multivariate logistic regression.The performance of models were evaluated by receiver oper-ating characteristic(ROC)curve.Results There were significant differences in the maximum tumor diameter,minimum tumor diameter,arterial phase enhancement degree,venous phase enhancement rate,arterial phase enhancement degree rate,venous phase enhance-ment degree rate,cystic,and necrosis between low-risk GST group and high-risk GST group,which were associated with the risk classification of GST.The area under the curve(AUC)of the quantitative features-based model that combined maximum tumor diam-eter,minimum tumor diameter,arterial phase enhancement degree,venous phase enhancement rate,arterial phase enhancement degree rate and venous phase enhancement degree rate,showed a significantly higher performance than the qualitative features-based model that incorporated cystic and necrosis(0.981 vs 0.850,P<0.001).Conclusion Maximum tumor diameter,minimum tumor diameter,arterial phase enhancement degree,venous phase enhancement rate,arterial phase enhancement degree rate,venous phase enhance-ment degree rate,as well as cystic and necrosis,are associated with the risk classification of GST and can predict the high-risk GST.

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.
