In this paper， 18 articles were included， and the demographic， physiological， psychological and social factors affecting the psychological distress of patients with coronary heart disease were systematically analyzed， thus to provide a deeper understanding of psychological distress and offering references for formulating targeted intervention strategies.

Objective:To analyze the changing trends and international differences in the incidence and disability-adjusted life years (DALY) of hypertensive disorders in pregnancy (HDP) in China from 1990 to 2021 based on the Global Burden of Disease (GBD) database.Methods:The data were derived from the GBD database, covering the incidence and DALY data of HDP in countries or regions around the world. Descriptive statistics were used to compare the differences in disease burden between China and different regions of Europe, America and other developed countries, and to analyze the disease burden characteristics of women of childbearing age in different age groups (every 5 years). The Joinpoint regression model was used to identify trend change points. The age-period-cohort model was used to analyze the independent effects of age, period and birth cohort.Results:(1) From 1990 to 2021, the incidence of HDP in China showed an overall downward trend, from 387.18/100 000 in 1990 to 216.35/100 000 in 2021. Compared with the global incidence rate (1990: 1 167.28/100 000; 2021: 923.48/100 000), the incidence rate of HDP in China was relatively low, but it was still higher than that in some developed countries. (2) The analysis of the Joinpoint regression model showed that the incidence rate of HDP in different age groups first decreased, then increased, and finally leveled off. The connection point with the lowest point was in 2005. DALY showed a continuous downward trend in all age groups. Among them, the decline in maternal DALY of pregnant women in all age groups from 15 to 39 years old was more obvious. (3) The age-period-cohort effect model showed that the incidence rate and DALY of HDP in women of childbearing age aged 20 to 24 years reached their peak.Conclusions:The burden of HDP in China continues to decrease, and the disease prevention and control has achieved remarkable results, but the incidence rate is still higher than that in some developed countries. It is suggested that personalized interventions should be developed for different risk groups to further reduce the burden of disease.

OBJECTIVES: Mobile phone dependence has become increasingly prominent among university students, posing significant risks to their social functioning and mental health. Previous studies suggest that perfectionistic personality traits may be key psychological predictors of mobile phone dependence, but the underlying mechanisms remain unclear. This study aims to identify core symptoms of mobile phone dependence among university students and to examine the pattern of associations between different dimensions of perfectionism and mobile phone dependence. METHODS: A cross-sectional questionnaire survey was conducted among 1404 university students nationwide. The Mobile Phone Involvement Questionnaire (MPIQ) and the Forst Multidimensional Perfectionism Scale (FMPS) were used to assess mobile phone use and perfectionism traits. The EBIC-GLASSO network model was constructed to analyze the network structure linking perfectionism and mobile phone dependence. RESULTS: A total of 56.48% of university students in the sample met the criteria for mobile phone dependence. The total FMPS score was positively correlated with the total MPIQ score (r=0.47, P<0.001). Results of multiple linear regression controlling for demographic variables showed that dimensions of FMPS score significantly predicted MPIQ score (all P<0.05). Network analysis revealed that the central dimension in perfectionism is "organization" (expected influence=2.69) and the core symptom of mobile phone dependence was "I lose track of how much I am using my smartphone" (expected influence= 0.78). Bridge centrality analysis identified "organization" as a key bridging factor linking perfectionism and mobile phone dependence (bridge strength=1.96). Among the symptom-to-symptom connections, "parental expectations" showed the strongest positive association with "arguments have arisen with others because of my mobile phone use" (partial correlation coefficient=0.15), serving as a risk factor. In contrast, "organization" was most strongly negatively associated with the same symptom (partial correlation coefficient=-0.13), serving as a protective factor, suggesting a protective effect. CONCLUSIONS Mobile phone dependence is common among college students and is primarily characterized by a lack of self-control in phone use. Although perfectionism is generally positively associated with mobile phone dependence, its internal dimensions appear to exert a dual effect. Specifically, "parental expectations" and "doubt over actions" may increase the risk of mobile phone dependence, whereas "organization" serves as a protective factor, particularly against interpersonal conflicts related to phone dependency.

Cognitive decline is an early sign of dementia, mainly manifested as the ability to learn new knowledge and memory decline in the near future, so early detection, early diagnosis, early treatment are an important research direction to alleviate dementia population. Previous studies have shown that blood pressure variability (BPV) is an important risk factor for cognitive decline. At present, there is a lack of systematic understanding of the specific effects of BPV on different subdomains of cognitive function and the treatment standard of BPV. This paper reviews the existing clinical studies, emphasizes that abnormal BPV causes adverse cognitive outcomes in all age groups, and proposes future research directions.

Hypoplastic left heart syndrome is a congenital heart disease characterized by mitral and（or）aortic valve stenosis or atresia，leading to the hypoplasia of the left ventricle，ascending aorta and aortic arch.If not treated in time，most children die within a few weeks after birth.Congenital complete atrioventricular block is a rare congenital cardiac conduction disorder.When combined with severe cardiac malformations，the mortality rate is extremely high.In this case，a 26-year-old pregnant woman with a history of 3 pregnancies and 1 delivery，had a natural conception with monochorionic diamniotic twins. At 22 +5 weeks of gestation，it was first found that one of the twins had hypoplastic left heart syndrome with congenital complete atrioventricular block through fetal echocardiography detection.This situation was extremely rare，and there was a lack of clinical guidelines on how to manage the pregnancy and determine the time of delivery time.In this case，prenatal ultrasound was used to monitor and comprehensively evaluate fetal cardiac function through the cerebroplacental ratio（CPR）combined with the cardiovascular overall performance score（CVPS）.Pregnancy safety management was implemented，and a cesarean section was performed at an elective time.Another healthy fetus did not suffer any adverse effects. This case provides strong evidence for ensuring the safety of healthy fetus and mother in perinatal period.It is also confirmed that CPR and CVPS combined evaluation of fetal cardiac function and pregnancy outcome will be more accurate and comprehensive.This method is simple，accurate，non-invasive，and can be used as an effective method for clinical evaluation of fetal cardiac function.

Objective:To evaluate the short-term efficacy of our modified anterior pelvic ring internal fixator(INFIX) in the treatment of anterior pelvic ring injuries.Methods:A retrospective study was conducted to analyze the clinical data from the 16 patients with pelvic anterior ring injury who had been treated with our modified INFIX at Department of Orthopaedics, The First Hospital Affiliated to Bengbu Medical University from June 2020 to June 2023. There were 9 males and 7 females with an age of (49.1±14.3) years. According to the AO/OTA classification, 10 cases were of type B2 and 6 cases of type C1. Their time from injury to surgery was (7.6±2.9) days. Fixation with our modified INFIX was as follows: Three pedicle screws were inserted into the anterior inferior iliac spine on one side and into the pubic symphysis on both sides. Next, a subcutaneous tunnel was created from the anterior inferior iliac spine incision toward the pubic symphysis, and connecting rods were inserted for fixation. The surgical incision length, intraoperative blood loss, surgical time, postoperative fracture reduction quality, fracture healing time, incidence of complications during follow-up, and pelvic functional recovery at the last follow-up were recorded in this cohort.Results:In this cohort, surgical incision length was (5.8±0.4) cm, intraoperative blood loss (75.4±11.9) mL, and surgical time (66.1±8.9) min. By the end of one week after surgery, the quality of fracture reduction was evaluated according to the Matta scoring criteria as excellent in 11 cases and as good in 5 cases. All patients were followed up for (17.4±3.1) months after surgery. The fractures got united in all the 16 patients after (11.2±1.2) weeks. At the last follow-up, the pelvic function recovery was evaluated according to the Majeed scoring system as excellent in 13 cases and as good in 3 cases, yielding a Majeed score of (90.1±4.2) points. During the follow-up period, no patient developed complications such as nerve injury, wound infection, or loosening, breakage or withdrawal of internal fixation devices.Conclusion:In the treatment of anterior pelvic ring injuries, our modified INFIX has the advantages of few complications, simple operation and minimal invasion, leading to good short-term efficacy.

Anticipatory anxiety is a negative emotion that arises when individuals encounter potential threats or uncertainties in the future. It is the core symptom of a variety of anxiety disorders, and is closely associated with the occurrence, severity, treatment outcome, and prognosis of anxiety disorders, which has garnered a growing amount of focus in clinical practice. Nevertheless, scientific research on anticipatory anxiety continues to face obstacles such as unclear pathological mechanisms, the absence of simple and consistent self-assessment tools, and effective interventions. To improve understanding of the role of anticipatory anxiety in the diagnosis and treatment of anxiety disorders, this study reviews pertinent domestic and international literature, and briefly introduces the concept, assessment and measurement, activation paradigm, pathological mechanisms, and interventions of anticipatory anxiety.

In recent years, the convergent media environment, which integrates text, video, audio, animation, and other media forms, has become indispensable in higher education. Online teaching within this environment leverages a " cloud-based, multi-screen" dissemination model, effectively integrating various forms of media resources to accommodate mobile and ubiquitous learning scenarios. This approach meets the diverse needs of different learners, and makes course content delivery more dynamic while enhancing teacher-student interaction. As a result, it fosters innovation in course instruction, shifting teaching methods from " standardization" to " differentiation" , thereby providing a platform and resources for personalized learning. This paper analyzes the design and resource development strategies for Nuclear Medicine online courses within the convergent media environment from three perspectives: constructing a high-quality online course system centered on learning outcomes, driving innovation in online teaching focused on the learning experience, and highlighting the efficacy of cultivating high-quality nuclear medicine professionals through a top-tier online course. By systematically summarizing the implementation experience in building the Nuclear Medicine online course, this article aims to provide strategies and pathways to enrich the content supply and cross-platform integration of online medical courses in China.

OBJECTIVE: To review the clinical characteristics of patients with traumatic spinopelvic dissociation (SPD) and explore the diagnostic and therapeutic methods. METHODS: A clinical data of 22 patients with SPD who underwent surgical treatment between March 2019 and August 2024 was retrospectively analyzed. There were 13 males and 9 females, with an average age of 35.5 years (range, 14-61 years). The causes of injury included falling from height in 16 cases, traffic accidents in 5 cases, and compression injury in 1 case. Sacral fractures were classified based on morphology into "U" type (9 cases), "H" type (7 cases), "T" type (4 cases), and "λ" type (2 cases). According to the Roy-Camille classification, there were 4 cases of type Ⅰ, 12 cases of type Ⅱ, 2 cases of type Ⅲ, and 4 cases of type Ⅳ. The Cobb angle was (35.7± 22.0)°. Sixteen patients were accompanied by lumbosacral trunk and cauda equina nerve injury, which was classified as grade Ⅱ in 5 cases, grade Ⅲ in 5 cases, and grade Ⅳ in 6 cases according to the Gibbons grading. The time from injury to operation was 2-17 days (mean, 5.7 days). Based on the type of sacral fracture and sacral nerve injury, 6 cases were treated with closed reduction and minimally invasive percutaneous sacroiliac screw fixation, 16 cases were treated with open reduction and lumbar iliac fixation (8 cases)/triangular fixation (8 cases). Among them, 11 patients with severe fracture displacement and kyphotic deformity leading to sacral canal stenosis or bony impingement within the sacral foramen underwent laminectomy and sacral nerve decompression. X-ray films and CT were reviewed during followed-up. The Matta score was used to evaluate the quality of fracture reduction. At last follow-up, the Majeed score was used to assess the functional recovery, and the Gibbons grading was used to evaluate the nerve function. RESULTS: All operations were successfully completed. All patients were followed up 8-64 months (mean, 20.4 months). Two patients developed deep vein thrombosis of the lower limbs, 2 had incision infections, and 1 developed a sacral pressure ulcer; no other complications occurred. Radiological examination showed that the Cobb angle was (12.0±6.8)°, which was significantly different from the preoperative one ( t=6.000, P<0.001). The Cobb angle in 16 patients who underwent open reduction was (14.9±5.5)°, which was significantly different from the preoperative one [(46.8±13.9)° ] ( t=8.684, P<0.001). According to the Matta scoring criteria, the quality of fracture reduction was rated as excellent in 8 cases, good in 7 cases, fair in 5 cases, and poor in 2 cases, with an excellent and good rate of 68.2%. Bone callus formation was observed at the fracture site in all patients at 12 weeks after operation, and bony union achieved in all cases at last follow-up, with a healing time ranging from 12 to 36 weeks (mean, 17.6 weeks). At last follow-up, the Majeed score was rated as excellent in 7 cases, good in 10 cases, fair in 4 cases, and poor in 1 case, with an excellent and good rate of 77.3%. One patient experienced a unilateral iliac screw breakage at 12 months after operation, but the fracture had already healed, and there was no loss of reduction. Among the 16 patients with preoperative sacral nerve injury, 11 cases showed improvement in nerve function (6 cases) or recovery (5 cases). CONCLUSION SPD with low incidence, multiple associated injuries, and high incidence of sacral nerve injury, requires timely decompression of the sacral canal for symptomatic sacral nerve compression, fractures reduction, deformities correction, and stable fixation.
