Esophageal squamous cell carcinoma (ESCC) poses a significant global health challenge, necessitating early detection, timely diagnosis, and prompt treatment to improve patient outcomes. Endoscopic examination plays a pivotal role in this regard. However, despite the availability of various endoscopic techniques, certain limitations can result in missed or misdiagnosed ESCCs. Currently, artificial intelligence (AI)-assisted endoscopic diagnosis has made significant strides in addressing these limitations and improving the diagnosis of ESCC and precancerous lesions. In this review, we provide an overview of the current state of AI applications for endoscopic diagnosis of ESCC and precancerous lesions in aspects including lesion characterization, margin delineation, invasion depth estimation, and microvascular subtype classification. Furthermore, we offer insights into the future direction of this field, highlighting potential advancements that can lead to more accurate diagnoses and ultimately better prognoses for patients.

Premature ovarian insufficiency (POI) leads to reproductive aging in young women, such as reduced fertility and reduced hormone levels, which seriously affects women's physical and mental health and quality of life. The pathogenesis of POI is still unclear, and there is a large unknown space. In-depth exploration of its etiology and mechanism using animal models has important clinical significance, which can help identify and avoid risk factors in advance, and formulate targeted prevention and treatment strategies. Through the analysis and study of different POI mouse models, this paper can provide a reference for the basic research of POI and a new idea for improving the fertility of women of childbearing age.

Objective:To explore the influencing factors of the subjective well-being of elderly individuals and improve the accuracy of well-being predictions.Methods:A multi-stage stratified sampling method was conducted in Guangdong province and Guangxi Zhuang autonomous region from August 2019 to October 2020. The health status and subjective well-being of older adults were assessed using a self-administered multidimensional health questionnaire, while overall well-being was evaluated with a single-item 5-point scale. The statistical analysis was performed using R software (version 4.3.2), with analytical methods including χ2 tests, univariate analysis, quantile regression and random forest model. Results:A total of 2 620 participants were recruited, and 70.9% of whom reported feeling happy.The depression symptom score of the elderly was 3.00(1.00, 6.00), emotional status score was (28.26±4.14), activities of daily living (ADL) score was 69.00(52.00, 81.00), and the body mass index(BMI) was (22.68±3.81)kg/m 2.The quantile regression results indicated that marital status (married)(Q 10: β=0.049; Q 50: β=0.014; Q 90: β=0.005) and depressive symptoms (no depression, depressive tendency)(Q 10: β=1.000; Q 50: β=1.000; Q 90: β=0.025) had varying effects on older adults' subjective well-being across three quantiles (Q 10, Q 50, Q 90)(all P<0.05). In contrast, social activity (no social activity)(Q 10: β=-0.072; Q 50: β=-0.011; Q 90: β=-0.006), ADL (severe disability, moderate disability, mild disability)(Q 10: β=-0.103, Q 50: β=-0.006, Q 90: β=-0.048; Q 10: β=-0.063, Q 50: β=-0.012, Q 90: β=-0.005; Q 10: β=-0.078, Q 50: β=-0.016, Q 90: β=-0.009), and emotional status (poor emotion, fair emotion)(Q 10: β=-0.261, Q 50: β=-0.009, Q 90: β=-0.025; Q 10: β=-0.140, Q 50: β=-0.017, Q 90: β=-0.029) had a negative impact on elderly subjective well-being at the three quantile points(all P<0.05). Random forest results indicated that depressive symptoms, ADL, emotional status, household monthly income per capita, BMI, social activity, multimorbidity status, and marital status were the most important determinants of subjective well-being. Conclusion:Depressive symptoms and emotional status have a significant impact on the subjective well-being of older adults. Additionally, ADL, household income per capita, BMI, and social engagement also play important roles in influencing well-being, while the emotional support provided by marriage should not be overlooked.

Objective:To investigate the relationship between serum matrix metalloproteinase-9 (MMP-9) level and the location and severity of bleeding in patients with cerebral microbleeds(CMBs).Methods:A total of 60 CMBs patients admitted to the Department of Neurology of the First Affiliated Hospital of the Xinxiang Medical University from January 2019 to August 2020 were selected as subjects as the CMBs group, and 60 healthy controls without nervous system diseases in outpatient physical examination during the same period were selected as the control group. The clinical data and biochemical indicators of the two groups were collected. Serum MMP-9 levels were measured by enzyme linked immunosorbent assay (ELISA). According to susceptibility weighted imaging (SWI), CMBs patients were divided into grade 1 group ( n=24), grade 2 group ( n=19) and grade 3 group ( n=17), and according to the micro analytical rating scale (MARS), the CMBs patients were divided into the lobar group ( n=19), the deep or infratentorial group ( n=17) and the mixed group ( n=24).The relationship between serum MMP-9 level and the location and severity of CMBs was analyzed. SPSS 19.0 software was used for data statistical analysis.One-way ANOVA, t-test and rank sum test were used for comparison. Logistic regression analysis was used to analyze the influencing factors. Pearson correlation analysis and Spearman correlation analysis were used for correlation analysis. Results:The level of MMP-9 in CMBs group was significantly higher than that in control group (208.13(142.25, 285.88) μg/L, 149.50(93.40, 186.51)μg/L), and the difference was statistically significant ( P<0.05). Serum MMP-9 level was a risk factor of CMBs ( β=1.322, OR=3.750, 95% CI=2.038-7.997, P=0.002). The difference of level of MMP-9 in different severity of CMBs was statistically significant (147.55(109.25, 266.47)μg/L, 242.12(147.55, 288.80)μg/L, 270.42(203.43, 364.27)μg/L, P=0.017). Serum MMP-9 level was positively correlated with the number of CMBs ( r=0.371, P=0.003). The difference of MMP-9 level of CMBs in different locations were statistically significant (249.77(158.43, 338.46)μg/L, 188.83(138.52, 243.15)μg/L, 210.65(144.25, 255.78)μg/L, P=0.013). The increased serum MMP-9 level was a risk factor for CMBs( β=0.401, OR=1.122, 95% CI=1.004-1.204, P=0.036). Conclusion:The increased level of serum MMP-9 may be a risk factor of CMBs, especially for CMBs in cerebral lobesand, and the level of MMP-9 is positively correlated with the severity of CMBs.

Objective:To investigate and compare the effectiveness and safety of infrared bipolar radiofrequency (IR-RF) and nonablative fractional laser (NAFL) including 1 540 nm Er: glass and 1 927 nm thulium-doped laser, so as to choose a better pathway for clinical treatments on periorbital wrinkles.Methods:A prospective randomized self-controlled study was conducted in the Department of Laser and Aesthetic Medicine, Shanghai Ninth People’s Hospital. A total of 27 patients divided into 3 groups by random number table underwent split-face treatments between December 2019 and January 2021. Two of the three treatments were selected randomly for patients in each group: Group A, left side IR-RF vs. right side 1 540 nm NAFL; Group B, left side IR-RF vs. right side 1 927 nm NAFL; Group C, left side 1 540 nm NAFL vs. right side 1 927 nm NAFL. In total 3 sessions were given at 2 months interval. Therapeutic outcomes were evaluated by subjective (GAIS and Fitzpatrick wrinkle score) and objective (VISIA-CR) assessments. Side effects and pain visual evaluation (VAS) were also recorded. Wilcoxon signed-rank tests were used to evaluate the differences among the three therapeutic method , and relationships with VAS and patients’ age.Results:In total 30 patients (10 in each group) were recruited and finally 27 cases completed all treatments and follow-ups: Group A, 9 patients (male 3, female 6); Group B, 8 patients (male 3, female 5); Group C, 10 patients (male 4, female 6). The age distributions: Group A, 33-65 years, mean 36.9 years; Group B, 28-67 years, mean 38.6 years; Group C, 25-58 years, mean 37.8 years. GAIS comparisons: no statistical differences were found in each group between baseline and post-treatment ( P>0.05). Fitzpatrick wrinkle score: the overall analysis showed significant improvements were not found in IR-RF treated-side but were observed in 1 540 nm and 1 927 nm NAFL treated sides ( P<0.05). Furthermore, the 1 927 nm NAFL treated side showed more decreased scores than 1 540 nm NAFL treated side ( P<0.05). The VISIA analysis of feature counts of skin texture showed similar result. Besides, the patients over 50 years old showed significantly improvements compared with the ones under this age threshold in IR-RF treated sides ( P<0.05). The pain VAS in IR-RF treated side was significant lower than NAFL-treated side (2.2 vs. 5.8, P<0.05). Only one patient reported post-inflammatory hyperpigmentation (PIH) in 1540 nm NAFL treated side, which disappeared progressively in 4 months after last treatment. Conclusion:Nonablative fractional laser is effective and safe in improving periorbital wrinkles. Infrared bipolar radiofrequency might be more suitable for elderly patients especially with low pain level.
