Objective To investigate the diagnostic value of endoscopic sign of light blue crest(LBC)capsuling papillary lesion(LCPL)for high-risk intestinal metaplasia(IM).Methods A total of 314 patients(352 biopsy specimens)who underwent endoscopic examination and biopsy in Department of Gastroenterology of Army Medical Center of PLA from January 2021 to June 2023 were recruited,and HE and HID-AB staining(the golden standard of high-risk IM)were apllied to detect the histological types and IM types.The samples were subsequently divided into chronic inflammation group,low-risk IM group,high-risk IM group,well-differentiated intestinal-type gastric cancer group,and poorly-differentiated intestinal-type gastric cancer group.The positive rate of LCPL in each group and its diagnostic efficacy were analyzed based on endoscopic images of the biopsy sites.Logistic regression analysis was used to investigate the relationship between LCPL sign and high-risk IM,as well as the clinical and pathological features associated with LCPL sign.Receiver operating characteristic(ROC)curve was plotted to evaluate the diagnostic efficacy of LCPL for high-risk IM,using indicators such as sensitivity,specificity,Youden index and area under the curve(AUC).Results The positive rate of the LCPL sign in high-risk IM group was 75.70%,significantly higher than that of the other groups(all P<0.001).Logistic regression analysis showed that LCPL sign was significantly correlated with high-risk IM(OR=30.286,95%CI:13.528～67.804,P<0.001).When the sign was employed in diagnosing high-risk IM,the sensitivity was 69.84%,the specificity was 93.75%,the Youden's index was 0.636,and the AUC value was 0.818(95%CI:0.773～0.857).Besides sensitivity,all above parameters of LCPL sign showed significantly better diagnostic efficacy than those of traditional LBC sign,which is used as a sign for diagnosing IM(P<0.001).Moreover,recognition of LCPL sign was not easily affected by age(OR=1.130,95%CI:0.709～1.800,P=0.607),lesion site(Angular incisure:OR=2.360,95%CI:0.732～7.613,P=0.151;Autrum:OR=2.257,95%CI:0.756～6.744,P=0.145),and presence of peptic ulcers(OR=1.085,95%CI:0.208～5.652,P=0.923).Significantly,94.12%of positive and 66.94%of negative LCPL signs could be rapidly recognized within 3 s(OR=4.536,95%CI:1.372～14.997,P=0.013).Conclusion LCPL sign shows high efficacy and potential clinical application value for high-risk IM in gastric mucosa of endoscopic diagnosis.

Objective To explore the barriers to postoperative self-management behaviors in patients with pituitary adenoma and provide a theoretical basis for developing nursing intervention strategies.Methods Using a purposive sampling method,16 postoperative pituitary adenoma patients admitted to a tertiary hospital in Zhengzhou from July 2024 to January 2025 were selected for semi-structured interviews.The interview data were analyzed and refined through Colaizzi's phenomenological analysis method.Results A total of 4 themes and 12 subthemes were extracted,including postoperative physiological dysfunction(sensory dysfunction,difficulty in managing diabetes insipidus,fatigue syndrome),psychosocial adaptation barriers(self-image distress,fear of disease recurrence,restricted information delivery),challenges in maintaining health behaviors(environment-behavior conflicts,insufficient adherence to medication and activity guidelines,inadequate complication management),deficiencies in support systems(non-specific postoperative guidance,poor communication channels,insufficient coordination of medical resources).Conclusion Postoperative self-management behaviors in pituitary adenoma patients are influenced by multidimensional factors,necessitating comprehensive intervention strategies addressing physiological,psychological,behavioral,and systemic support levels.

Glioma is the most common primary malignant brain tumor in the adult population,characterized by high incidence and low sur-vival rates.Current standard treatment options exhibit limited efficacy.In recent years,the crucial role of cGAS-STING signaling in tumor im-munity has garnered significant attention.This article systematically reviews the molecular mechanisms of cGAS-STING signaling in glioma and its potential tumor-suppressive effects,providing an in-depth exploration of various STING agonists and their delivery systems targeting this pathway.This review also summarizes the synergistic effects of combining cGAS-STING pathway activation with radiotherapy,chemo-therapy,and immune checkpoint inhibitors,providing substantial references for the development of multimodal comprehensive treatment strategies.

Objective:To observe the effect of different exercise methods on the prevention and treatment of senile sarcopenia.Methods:A cross-sectional investigation was carried out to select the elderly who visited the First Affiliated Hospital of Zhejiang University School of Medicine and Tongxiang Hospital of Traditional Chinese Medicine from October 2016 to December 2023 for medical check-ups at the geriatrics department and physical examination center.General information was collected, and the Hologic Discovery-Wi bone density scanner(Hologic, USA)was used to measure appendicular lean mass(ALM).Walking speed over 6 meters and grip strength were measured, and the appendicular skeletal muscle index(ASMI=limb muscle mass/height 2)was calculated.The subjects were divided into three groups aged 60-69, 70-79, and 80-89 years and the relevant information was obtained through standard questionnaires.Based on the exercise methods and time, each age group was categorized into three groups: non-exercise, aerobic exercise, and resistance exercise.Differences in related indicators of sarcopenia among the elderly in different age groups with different exercise methods were analyzed. Results:In all three age groups, the ASMI of the resistance exercise group was higher compared to the aerobic exercise and non-exercise groups: In the 60-69 years old group, (7.50±0.31)kg/m 2vs.(6.93±0.37)kg/m 2 and (6.81±0.27)kg/m 2, F=38.146, P<0.001; In the 70-79 years old group, (7.26±0.30)kg/m 2vs.(6.82±0.38)kg/m 2 and (6.50±0.36)kg/m 2, F=35.784, P<0.001; In the 80-89 years old group, (7.00±0.59)kg/m 2vs.(6.53±0.63)kg/m 2 and (5.89±0.66)kg/m 2, F=23.380, P<0.001.The resistance exercise group also had higher grip strength than the aerobic and non-exercise groups: In the 60-69 years old group, (39.23±1.78) kg vs.(26.21±4.79) kg and (24.68±3.55) kg, F=127.806, P<0.001; In the 70-79 years old group, (37.78±2.50) kg vs.(27.21±5.47) kg and (24.43±3.49) kg, F=75.265, P<0.001; In the 80-89 years old group, (28.75±4.71) kg vs.(21.37±5.57) kg and (17.08±4.50) kg, F=33.148, P<0.001; Both the resistance and aerobic exercise groups had a faster walking speed compared to the non-exercise group: 60-69 years old group (1.30±0.14) m/s and (1.31±0.15) m/s compared to (1.20±0.14) m/s, F=5.905, P=0.003; 70-79 years old group (1.26±0.13) m/s and (1.24±0.17) m/s compared to (1.16±0.16) m/s, F=4.931, P=0.009; and (1.00±0.20) m/s and (1.02±0.27) m/s over (0.84±0.24) m/s in the group of 80-89 years old, F=6.913, P=0.001.The results of two-by-two comparisons showed that among the older adults in the 70-79 and 80-89 age groups, ASMI was higher in the aerobic exercise group than in the non-exercise group ( t=0.070, 0.048, both P<0.001), and grip strength was higher in the aerobic exercise group than in the non-exercise group ( t=0.885, 0.976, P=0.002, <0.001); however, there was no difference in step speed between the resistance exercise group and the aerobic exercise group among older adults in the three age groups ( t=0.031, 0.035, 0.701, P=0.605, 0.593, 0.841). Conclusions:Compared with non-exercise and aerobic exercise, resistance exercise has a clear effect on the prevention and treatment of sarcopenia in the elderly.As age increases, aerobic exercise can also prevent and treat sarcopenia in the elderly aged 70-89 years.Both resistance exercise and aerobic exercise have obvious effect on maintaining the pace of the elderly.

To explore the application of sequential analysis in post-market safety dynamic surveillance of vaccines. Under the dynamic monitoring data of vaccines post-market approval, this research introduces the fundamental principles of maximizing sequential probability ratio test (MaxSPRT) and Bayesian sequential analysis, employing R software. Through an example of dynamic safety monitoring data of vaccines post-market approval, we analyze using the MaxSPRT and Bayesian sequential analysis. The MaxSPRT identified a safety signal in week 4 ( P<0.05), while Bayesian sequential analysis indicated that the 95% highest density interval for the RR value at week 4 is 1.13-3.27, suggesting the first appearance of a safety signal at week 4. The MaxSPRT and Bayesian sequential analysis effectively leverage continuously accumulating dynamic monitoring data, thereby serving as a valuable method for post-market safety surveillance of vaccines.
