Objective:To investigate the characteristics of Internet addiction(IA)in adolescents with depression and explore its relationship with impulsivity and aggressive personality traits.Methods:A total of 71 adolescent patients with depressive disorders were recruited from the Child Psychiatry Outpatient Clinic of Peking University Sixth Hospital between April 2021 and November 2022 (15 males, 56 females; median age 14 [13, 15] years) as the depressive disorder group. Additionally, 83 healthy adolescents (27 males, 56 females; median age 14 [13, 17] years) were recruited as the control group during the same period. Internet addiction was assed using the Chinese version of Young′s Internet Addiction Test (YIAT), with a total score≥50 indicating internet addiction. Impulsivity was evaluated using the Barratt Impulsiveness Scale-11(BIS-11), and aggression was measured with the Buss-Perry Aggression Questionnaire(BPAQ). Differences in internet addiction, impulsivity, and aggression between the depression group and the control group were analyzed. Pearson correlation analysis was used to explore the correlation between internet addiction and impulsivity, aggression. Hierarchical linear regression models were used to analyze the factors influencing internet addiction, and a parallel mediation model was used to examine the mediating effect of impulsivity and aggressive personality traits in the relationship between depressive disorders and internet addiction.Results:The prevalence of IA was significantly higher in adolescents with depression than the healthy control group [57.75%(41/71) vs 31.33%(26/83); χ 2=10.87, P<0.001]. Adolescents with depressive disorders also exhibited higher impulsivity (65.5±9.2 vs 57.0±9.2, t=-5.72, P<0.001) and aggression (56.3±16.0 vs 42.4±15.1, t=-5.13, P<0.001) compared to the control group. Internet addiction was positively correlated with aggression ( r=0.47, P<0.01) and impulsivity ( r=0.57, P<0.01). Hierarchical regression analysis with the YIAT total score as the dependent variable revealed that impulsivity ( β=0.48, P<0.001) and aggression ( β=0.24, P<0.001) significantly predicted internet addiction. Mediation analysis indicated that depressive disorders indirectly indirectly influenced internet addiction through parallel paths of impulsivity and aggression, with a total indirect effect of 0.543 (95% CI: 0.362-0.761). Conversely, internect addiction influenced depressive disorders through reverse parallel pathway of impulsivity and aggression with a total indirect effect of 0.038 (95% CI: 0.021-0.067). Direct effects were not significant in either direction. Conclusion:Adolescents with depressive disorders exhibit more internet addiction. Impulsivity and aggressive personality traits play bidirectional mediating roles in the relationship between depressive disorders and internet addiction.

Objective To investigate the perioperative outcomes and postoperative pregnancy outcomes of patients with intrauterine adhesions(IUA)treated by see-and-treat hysteroscopy and traditional hysteroscopy in transcervical resection of adhesions(TCRA).Methods A retrospective cohort study was performed on 485 patients with moderate-to-severe IUA who met the inclusion criteria and admitted in our hospital from January 2019 to December 2021.According to surgical approaches,the patients were assigned into a see-and-treat mode group and a traditional mode group.After clinical diagnosis(ultrasound and symptoms)of IUA,the patients from the former group received direct hysteroscopic adhesion separation surgery,and those of the latter group were diagnosed by outpatient hysteroscopy first and then hysteroscopic adhesion separation surgery.The perioperative indicators,postoperative three-dimensional transvaginal ultrasound(3D-TVUS)examination related characteristics,postoperative menstrual recovery,postoperative pregnancy outcomes,obstetric related complications,and neonatal outcomes were collected and compared between the 2 groups.Results Among the enrolled 485 patients,there were 277 in the see-and-treat group and 208 in the traditional group.The success rate of surgical treatment was 89.89%in the see-and-treat group and 92.79%in the traditional group,but no statistical difference was seen between them(Chi-square=1.234,P=0.267).3D-TVUS examination displayed that the see-and-treat mode group obtained better improvement of endometrial morphology,uterine morphology and menstruation after operation than the traditional group(P<0.001).The postoperative pregnancy rate was slightly higher in the see-and-treat group than the traditional mode group(58.84%vs 58.17%,P=0.882).However,the see-and-treat mode showed obvious advantage in the postoperative natural pregnancy rate,with a rate of 90.80%,obviously higher than that in the traditional mode group(81.82%,P=0.026).The live birth rate was 70.55%in the see-and-treat mode group,excluding 1 case with ongoing pregnancy in the second trimester and 1 case with ongoing pregnancy in the third trimester,and the rate was 74.38%in the traditional group,excluding 3 cases with ongoing pregnancy in the third trimester,but there was no statistical difference between the 2 groups(P=0.303).In terms of obstetric-related complications,there were 0 cases of blood transfusion during delivery hospitalization in the see-and-treat group,while there were 7 cases in the traditional group(P=0.003).In neonatal outcomes,the rate of transfer to the pediatric department was 10.43%in the see-and-treat mode group and 22.22%in the traditional mode group(P=0.021).For health economics,the see-and-treat hysteroscopy group demonstrated a significant advantage over the traditional hysteroscopy group(P<0.001).There was no significant difference in pain scores between the 2 groups.Conclusion The see-and-treat approach is a safe,feasible,and highly efficient strategy for integrating the diagnosis and treatment of IUA,enabling maximal minimization of surgical trauma while optimizing time and cost efficiency.

Objective:To explore the effect of nursing scheme based on self-regulation theory (SRT) on self-efficacy and quality of life of patients with chronic pancreatitis, and to provide basis for better promoting patients′ rehabilitation.Methods:Using a non-random historical control study, 55 patients with chronic pancreatitis admitted to The Fifth Affiliated Hospital of Southern Medical University from November 2021 to October 2022 were classified as the control group, and 55 patients with chronic pancreatitis admitted from November 2022 to October 2023 were classified as the research group. The control group received routine nursing intervention, while the research group received SRT-based nursing intervention. Both groups received a 3-month intervention. The General Self-Efficacy Scale, Exercise of Self-Care Agency Scale, Self Rated Abilities for Health Practices Scale, and Gastrointestinal Quality of Life Index were used to evaluate the self-efficacy, self-care ability, health behavior, and quality of life of two groups before and after the intervention, and statistical comparisons were made.Results:Both groups of patients completed the study. There were 28 males and 27 females in the control group. The age was (45.33 ± 12.26) years old. There were 30 males and 25 females in the research group. The age was (45.48 ± 12.61) years old. After the intervention, the score of the self-efficacy in the research group was (29.32 ± 2.88) points, which was higher than that in the control group (19.28 ± 1.95) points, the difference was significant ( t=21.41, P<0.05). The scores of self-care skills, self-responsibility, self-concept, health knowledge and the total score of the self-care ability in the research group were (35.32 ± 2.31), (22.85 ± 1.42), (25.88 ± 1.93), (64.32 ± 5.22), (148.34 ± 8.33) points respectively. They were all higher than those of the control group (28.66 ± 1.77), (17.22 ± 1.23), (18.67 ± 1.86), (60.08 ± 4.52), (124.56 ± 8.92) points. The differences were significant ( t values were 4.55-22.23, all P<0.05). The scores of exercise, nutrition, health responsibility, psychological comfort and the total score of the health behavior in the research group were (25.58 ± 1.41), (25.02 ± 2.03), (24.31 ± 2.34), (25.16 ± 1.63), (100.05 ± 7.36) points respectively. They were all higher than those of the control group (22.31 ± 2.03), (20.15 ± 2.82), (20.16 ± 2.89), (21.15 ± 2.17), (83.79 ± 7.84) points. The differences were significant ( t values were 8.28-11.21, all P<0.05). The scores of social activity, psychological state, physiological function, self-conscious symptoms and the total score of the quality of life in the research group were (16.78 ± 1.26), (17.03 ± 1.85), (22.43 ± 1.96), (17.09 ± 0.88), (73.41 ± 4.22) points respectively. They were all higher than those of the control group (15.32 ± 1.15), (15.34 ± 1.76), (20.86 ± 1.59), (16.03 ± 0.75), (67.52 ± 4.18) points. The differences were significant ( t values were 4.61-7.35, all P<0.05). Conclusions:SRT-based nursing scheme can effectively improve the self-efficacy and self-care ability of patients with chronic pancreatitis, and improve their health behavior and quality of life.

The transformation of the efficiency of Party building in public hospitals is a systematic project that requires the establishment of a collaborative mechanism characterized by the leadership of the Party committee,the drive of branch organi-zations,and the participation of all staff.A certain tertiary-level hospital in Fujian has broken free from the path-dependence of the traditional hierarchical Party building model.Based on the"goose formation"pattern,it has optimized the three-level em-powerment governance system of"head goose leading the way,strong goose consolidating the chain,and group goose collabora-ting",which provides an effective path for the transformation of Party building efficiency into governance efficiency and offers a paradigm reference for the innovation of the modern governance system led by Party building in public hospitals.

Objective: To evaluate the efficacy and prognosis of loop cutaneous ureterostomy (LCU) in the treatment of primary obstructive megaureter (POM) with severe hydroureteronephrosis (HUN) in infants under 1 year of age，so as to provide reference for infants unsuitable for stage-Ⅰ ureteral reimplantation. Methods: A retrospective analysis was conducted on 12 infants with POM and severe HUN treated with LCU in our hospital during Jan.2019 and Dec.2023.The clinical characteristics，surgical techniques，indications，postoperative complications，stage-Ⅱ surgical approaches，and follow-up outcomes were summarized. Results: All operations were successful，with an average operation time of (37.08±7.53) min (6 left-sided LCU and 6 right-sided LCU).During the mean follow-up of (10.12±2.70) months，all infants showed clinical improvement，with complete resolution or significant alleviation of hydronephrosis，reduced ureteral diameter，and increased renal cortical thickness.Complications included asymptomatic bacteriuria in 3 cases (25%) and urinary tract infection (UTI) in 1 case，all resolved with oral antibiotics.Four cases developed peristomal rashes，which improved with topical treatment.Eleven infants underwent stage-Ⅱ Cohen ureterovesical reimplantation at a mean age of (15.20±2.07) months.Notably，27.3%(3/11) required ureteral tailoring or plication during reimplantation，which reduced the risk of ischemic necrosis from excessive trimming.During the follow-up of (22.17±13.93) months，hydronephrosis and renal function improved，and no febrile UTI or bladder dysfunction occurred. Conclusion: LCU is a safe and effective method，which can provide adequate urinary drainage，relieve obstruction，stabilize renal function，and allow time for ureteral maturation and renal parenchymal recovery.LCU also facilitates subsequent stage-Ⅱ surgery by reducing ureteral dilation.

Conclusions:SRT-based nursing scheme can effectively improve the self-efficacy and self-care ability of patients with chronic pancreatitis, and improve their health behavior and quality of life.

Objective:To investigate the characteristics of Internet addiction(IA)in adolescents with depression and explore its relationship with impulsivity and aggressive personality traits.Methods:A total of 71 adolescent patients with depressive disorders were recruited from the Child Psychiatry Outpatient Clinic of Peking University Sixth Hospital between April 2021 and November 2022 (15 males, 56 females; median age 14 [13, 15] years) as the depressive disorder group. Additionally, 83 healthy adolescents (27 males, 56 females; median age 14 [13, 17] years) were recruited as the control group during the same period. Internet addiction was assed using the Chinese version of Young′s Internet Addiction Test (YIAT), with a total score≥50 indicating internet addiction. Impulsivity was evaluated using the Barratt Impulsiveness Scale-11(BIS-11), and aggression was measured with the Buss-Perry Aggression Questionnaire(BPAQ). Differences in internet addiction, impulsivity, and aggression between the depression group and the control group were analyzed. Pearson correlation analysis was used to explore the correlation between internet addiction and impulsivity, aggression. Hierarchical linear regression models were used to analyze the factors influencing internet addiction, and a parallel mediation model was used to examine the mediating effect of impulsivity and aggressive personality traits in the relationship between depressive disorders and internet addiction.Results:The prevalence of IA was significantly higher in adolescents with depression than the healthy control group [57.75%(41/71) vs 31.33%(26/83); χ 2=10.87, P<0.001]. Adolescents with depressive disorders also exhibited higher impulsivity (65.5±9.2 vs 57.0±9.2, t=-5.72, P<0.001) and aggression (56.3±16.0 vs 42.4±15.1, t=-5.13, P<0.001) compared to the control group. Internet addiction was positively correlated with aggression ( r=0.47, P<0.01) and impulsivity ( r=0.57, P<0.01). Hierarchical regression analysis with the YIAT total score as the dependent variable revealed that impulsivity ( β=0.48, P<0.001) and aggression ( β=0.24, P<0.001) significantly predicted internet addiction. Mediation analysis indicated that depressive disorders indirectly indirectly influenced internet addiction through parallel paths of impulsivity and aggression, with a total indirect effect of 0.543 (95% CI: 0.362-0.761). Conversely, internect addiction influenced depressive disorders through reverse parallel pathway of impulsivity and aggression with a total indirect effect of 0.038 (95% CI: 0.021-0.067). Direct effects were not significant in either direction. Conclusion:Adolescents with depressive disorders exhibit more internet addiction. Impulsivity and aggressive personality traits play bidirectional mediating roles in the relationship between depressive disorders and internet addiction.

The pathogenesis theory of"spleen deficiency and stasis toxin"in gastric cancer holds that spleen is the source of generation and transformation of qi and blood,that spleen deficiency is the internal basis of disease and throughout the disease.Stasis toxin is based on spleen deficiency,which is the fundamental pathogenesis of gastric cancer.In the pathological process of gastric cancer,a variety of metabolic substances in tumor cells and tumor microenvironment,mainly glucose metabolic reprogramming,undergo metabolic changes to reconstruct the phenotype and function of tumor-related macrophages,which is consistent with the pathogenesis theory of"spleen deficiency and stasis toxin".Therefore,this article focused on the reprogramming of glucose metabolism in tumor microenvironment to drive the phenotypic remodeling of tumor-related macrophages,explored the scientific connotation of the pathogenesis theory of"spleen deficiency and stasis toxin"of gastric cancer,and provided references for the theoretical and clinical research on the treatment of gastric cancer by TCM.

Ocular accommodation refers to the process by which the ciliary muscle creates a clear image of the object in the retina by changing the refractive power of the lens. When the accommodation ability of the eye is insufficient, the imaging focus falls on the region behind the retina and hyperopic defocus is easily formed, resulting in axial growth and leading to the development of myopia, and it is found that most myopic patients usually have some accommodation dysfunction. Myopia has become a public health problem in China, and the prevalence of adolescents has increased dramatically. How to prevent and stop the occurrence and development of myopia is a major challenge. Previous studies have found that ocular accommodation dysfunction is associated with the occurrence and development of myopia, and the measurement of parameters related to accommodation function has certain guiding significance for the prevention and control of myopia. The purpose of this paper is to review the correlation between myopia and ocular accommodation function, with a view to providing new ideas for the prevention, control and treatment of myopia.
