Objective: To analyze the developmental trajectories of clustered health risk behaviors and their association with self-esteem and lonelinesss among junior high school students, so as to provide a reference for formulating comprehensive prevention and control measures of health risk behaviors among adolescents. Methods: In October 2023, 1 165 first year junior high school students from two schools of Jishou City in Hunan Province were selected by convenient sampling method for three follow up surveys (T1:October 2023; T2:April 2024; T3:October 2024). The Adolescent Health Risk Behavior Questionnaire, Rosenberg Self esteem Scale and Loneliness Scale were used to assess health risk behaviors, self esteem and loneliness, respectively. Latent growth curve modeling and latent growth mixture modeling were applied to analyze the developmental trajectories of clustered health risk behaviors among junior high school students. Logistic regression was used to analyze the association of the developmental trajectories of clustered health risk behaviors with self esteem and loneliness among junior high school students. Results: The overall developmental trajectories among junior high school students showed a declining trend (intercept=0.15, slope=-1.65, both P <0.05), with three heterogeneous categories:low risk improvement group ( n =862, 74.0%), moderate risk stable group ( n =260, 22.3%), and high risk deterioration group ( n =43, 3.7%). After adjusting the status of the left behind individuals，using the low risk improvement group as the reference category in multinomial Logistic regression analysis, results indicated that higher loneliness scores among junior high school students increased the risks of belonging to the moderate risk stable group ( OR=1.02, 95%CI =1.00- 1.04 ) and the high risk deterioration group ( OR=1.04, 95%CI =1.00-1.08), while higher self esteem scores reduced the risks of belonging to the moderate risk stable group ( OR=0.93, 95%CI =0.91-0.96) and the high risk deterioration group ( OR=0.88, 95%CI =0.83-0.94) (all P <0.05). Conclusions The overall trend of clustered health risk behaviors among junior high school students gradually improves, and the self esteem and loneliness are significant correlative factors. Targeted intervention measures should be developed for the junior high school students, with a focus on enhancing their self esteem and alleviating loneliness.

Depressive disorder is a common psychiatric condition clinically characterized by impaired cognitive function， which profoundly affects patients' daily living and social functioning. Despite extensive research on the mechanism underlying the interaction between ghrelin and depressive disorder， comprehensive reviews， summary， and systematic organization of these findings remain lacking. To address this gap， this study aims to conduct a systematic evaluation of the effects and mechanisms of ghrelin on cognitive function in patients with depressive disorder， thereby providing references for targeted clinical interventions. On October 20， 2024， literature exploring the role and mechanisms of ghrelin in improving cognitive function in depressive disorder was sourced from the CNKI， PubMed and Web of Science databases， covering the period from the inception of the database till October 20， 2024. Two researchers independently conducted literature screening and data extraction. Ultimately， 9 articles were included in this review. The findings suggest that ghrelin improves cognitive function in patients with depressive disorder through multiple mechanisms， including mitigating inflammatory responses， modulating oxidative stress， and activating the cyclic adenosine monophosphate response element binding protein-brain-derived neurotrophic factor （CREB-BDNF） signaling pathway.

Evading host immunity killing is a critical step for virus survival. Inhibiting viral immune escape is crucial for the treatment of viral diseases. Serine/threonine kinase 39 (STK39) was reported to play an essential role in ion homeostasis. However, its potential role and mechanism in viral infection remain unknown. In this study, we found that viral infection promoted STK39 expression. Consequently, overexpressed STK39 inhibited the phosphorylation of interferon regulatory factor 3 (IRF3) and the production of type I interferon, which led to viral replication and immune escape. Genetic ablation or pharmacological inhibition of STK39 significantly protected mice from viral infection. Mechanistically, mass spectrometry and immunoprecipitation assays identified that STK39 interacted with PPP2R1A (a scaffold subunit of protein phosphatase 2A (PP2A)) in a kinase activity-dependent manner. This interaction inhibited DDB1 and CUL4 associated factor 1 (DCAF1)-mediated PPP2R1A degradation, maintained the stabilization and phosphatase activity of PP2A, which, in turn, suppressed the phosphorylation of IRF3, decreased the production of type I interferon, and then strengthened viral replication. Thus, our study provides a novel theoretical basis for viral immune escape, and STK39 may be a potential therapeutic target for viral infectious diseases.

Digital technologies have become an integral part of complete denture restoration. With advancement in computer-aided design and computer-aided manufacturing (CAD/CAM), tools such as intraoral scanning, facial scanning, 3D printing, and numerical control machining are reshaping the workflow of complete denture restoration. Unlike conventional methods that rely heavily on clinical experience and manual techniques, digital technologies offer greater precision, predictability, and efficacy. They also streamline the process by reducing the number of patient visits and improving overall comfort. Despite these improvements, the clinical application of digital complete denture restoration still faces challenges that require further standardization. The major issues include appropriate case selection, establishing consistent digital workflows, and evaluating long-term outcomes. To address these challenges and provide clinical guidance for practitioners, this expert consensus outlines the principles, advantages, and limitations of digital complete denture technology. The aim of this review was to offer practical recommendations on indications, clinical procedures and precautions, evaluation metrics, and outcome assessment to support digital restoration of complete denture in clinical practice.

Objective:To investigate the clinical characteristics of left-sided infective endocarditis (IE) without underlying valvular heart diseases (VHD).Methods:This was a retrospective study. Clinical data of 206 patients with left-sided IE (age: (50.4±16.1) years; 144 males (69.9%)) discharged from Shanghai Sixth People′s Hospital Affiliated to Shanghai Jiao Tong University School of Medicine from June 2011 to May 2021 were retrospectively analyzed, including 129 cases with underlying VHD (IE+VHD group) and 77 cases without underlying VHD (IE group). The 6-month survival rate of patients after discharge was analyzed with Kaplan-Meier survival curve; and the 6-month survival rates of the patients with different sizes of endocardial vegetation and different treatment modalities in the IE group were further analyzed with log-rank method.Results:The proportions of patients with age ≥65 years old, arrhythmia and aortic valve involvement, and the in-hospital mortality in the IE group were significantly lower than those in the IE+VHD group ( P<0.05). However, the proportion of patients with fever and speech vague/limb movement disorder/headache, those with mitral valve involvement in the IE group were significantly higher than those in the IE+VHD group ( P<0.05). The median value of C-reactive protein (CRP) in the IE group was significantly higher than that in the IE+VHD group ( P<0.05). Nevertheless, the median value of N-terminal pro-B-type natriuretic peptide (NT-proBNP) in the IE group was significantly lower than that in the IE+VHD group ( P<0.05). There were as no significant differences in the positive rates of bacterial/fungal blood cultures and the proportion of patients with mitral and aortic valve involvement of endocardial vegetation between the two groups (all P>0.05). Kaplan-Meier survival curve analysis showed that there was no significant difference in 6-month survival rate of patients between the IE group and IE+VHD group (88.7% vs. 93.6%, log-rank χ2=0.887, P=0.346). In the IE group, the 6-month survival rate after discharge in patients with maximum diameter of vegetation ≤10 mm was higher than that in patients with maximum diameter of vegetation >10 mm (96.3% vs. 80.7%, log-rank χ2=4.111, P=0.043). There was no significant difference in 6-month survival rate between patients treated with antibiotics combined with surgery and those treated with antibiotics alone (96.2% vs. 78.6%, log -rank χ 2=2.976, P=0.084). Conclusion:Compared to left-sided IE patients with underlying VHD, patients without underlying VHD are likely to have a younger age, more mitral valve involvement and lower in-hospital mortality; for those patients with maximum diameter of vegetation ≤10 mm there is a higher survival rate, and antibiotics combined with surgery may help to improve the survival rate.

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.

Raynaud syndrome is a clinical syndrome characterized by paroxysmal vasospasms of the acral small arteries,and its pathogenesis is closely associated with the dynamic imbalance of yin and yang as elucidated by the theory of"yang transforming qi and yin shaping up body."The theory of"yang transforming qi and yin shaping up body"originated in Huangdi Neijing,which is aimed at that yang can be tangible essence,blood,fluid,and other substances belonging to the yin into an invisible qi,promote the internal and external zang-fu organs and qi of the body's operation;yin qi is transformed into tangible substances under the gasification effect of yang qi to nourish the organism,to consolidate the essence of internal zang-fu organs,and to maintain the balance of yin and yang in the body.This study innovatively employs this theory to systematically elucidate the dynamic pathomechanism evolution of Raynaud syndrome:at the beginning of the disease,the ischemic stage is dominated by the deficiency of yang qi and the inability of qi to transform yin;then the disease enters into the hypoxic stage and the dilatation stage,which are mostly caused by the lack of yang depression,the blockage of qi,and the over-excessive formation of yin;and finally,the yang transforms qi too much and yin is damaged and weak,and then reaches the stage of complication.In Raynaud syndrome,the key mechanism and pathology of"yang transforming qi"and"yin shaping up body"as well as the stage of the disease should be clarified,so that yang qi can be used as the basis to make up for yang deficiency,yang depression can be stretched out,yin evils such as cold condensation,blood stasis and water dampness can be transformed,heat and toxin can be eliminated,yin fluids can be restored,and the extremities can be warmed up.The disease will be convalesced gradually.

Objective To systematically analyze the characteristics of functioning and vocational competency of college students with disabilities and explore effective career development pathways and methods.Methods This study systematically examined the functional characteristics and occupational competency structure of college students with disabilities,and proposed pathways to enhance their career development,using Internation-al Classification of Functioning,Disability and Health(ICF),rehabilitation competency framework(RCF),and achievement motivation theory.Results The study analyzed the functional performance of college students with disabilities across dimensions such as body functions and structures,activities and participation,and environmental factors,as well as their impact on occupational activities,using the Core Sets for Vocational Rehabilitation and the WHO Disability Assessment Schedule 2.0(WHODAS 2.0).The study outlined the occupational competency framework for these students and proposed three synergistic pathways to enhance their career development,including empowerment,functional compensation,and inclusive environmental support,based on RCF and achievement motivation theory.Early in-tervention,professional career services and multi-stakeholder collaboration mechanisms were recommended to provide lifelong,personalized career counseling,guidance and support based on precise occupational needs and competency assessments.Conclusion The career development of college students with disabilities is influenced by multiple factors,including indi-vidual functional status,occupational competency and environmental conditions.Implementing strategies such as empowerment,functional compensation,and inclusive environmental support could safeguard their right to em-ployment in an inclusive workplace,effectively improving their employment quality and sustainable career devel-opment capabilities.

Objective:To analyze pancreatic cancer incidence and mortality data in China and worldwide and to provide data for pancreatic cancer prevention and control efforts.Methods:Data of pancreatic cancer incidence and mortality rates, along with historical and predictive data, were obtained from the GLOBOCAN 2022 database. Epidemiological characteristics of pancreatic cancer was analyzed by region, sex, age and Human Development Index (HDI). Spearman's correlation coefficient test was used to assess the relationship between HDI and age-standardized incidence rate (ASIR) and age-standardized mortality rate (ASMR).Results:In 2022, the global number of new cases and deaths of pancreatic cancer will be 511 thousand and 467 thousand, respectively, with an ASIR and ASMR of 4.7/10 5 and 4.2/10 5, respectively. North America and Europe had the highest pancreatic cancer incidence and mortality rates of 8.5/10 5 and 7.3/10 5, respectively. Global ASIR and ASMR in men were both 1.4 times higher than those in women. HDI levels were positively correlated with ASIR ( r=0.79, P＜0.001) and ASMR ( r=0.78, P＜0.001) of pancreatic cancer in all regions. The number of pancreatic cancer cases and deaths in China were 119 thousand and 106 thousand, respectively, while the ASIR and ASMR of pancreatic cancer were 4.4/10 5 and 3.9/10 5, respectively. Both ASIR and ASMR in men were both 1.5 times higher than those in women in China. The number of pancreatic cancer incidence and death cases in China in 2050 is predicted to be 216 thousand and 204 thousand cases, with an increase of 81.5% and 92.5% compared with 2022, respectively. Conclusions:The disease burden of pancreatic cancer varies significantly among different regions, genders and ages. Pancreatic cancer incidence and mortality are positively correlated with HDI. The incidence and mortality rates of pancreatic cancer in China are close to the global average, but the number of new cases and deaths is high. Prevention and control should be strengthened to improve the survival of pancreatic cancer patients.

Objective:To describe the epidemiological characteristics of breast cancer incidence in Qidong City between 1972 and 2021, and provide guidelines for preventive and control measures and strategies.Methods:The cancer registry data were collected and breast cancer incidences during 1972 and 2021 in Qidong by sex, age, and time were analyzed. Crude incidence rate (CR), China age-standardized rate (ASRC), world age-standardized rate (ASRW), annual percentage change (APC), and average annual percentage change (AAPC) were calculated by Joinpoint software. The age-period-cohort model was used to analyze the influence of age, period, and birth cohort on the changes in the incidence trend of breast cancer.Results:From 1972 to 2021, there were 6 929 patients with breast cancer in Qidong, accounting for 4.70% of all new cancer cases, with a CR of 12.35/10 5, a ASRC of 6.63/10 5, and a ASRW of 8.89/10 5. The truncated incidence rate among people aged 35-64 years was 21.90/10 5. The cumulative incidence rate of the ages between 0 and 74 years was 0.96%. The cumulative risk was 0.96%. There were 98 male patients, whose CR, ASRC, and ASRW were 0.35/10 5, 0.17/10 5, and 0.25/10 5, respectively. The number of female patients was 6 831, and the CR, ASRC, and ASRW were 24.02/10 5, 12.86/10 5, and 17.13/10 5, respectively. The AAPC of ASRW of female breast cancer was 3.45% (95% CI: 2.90%-4.01%). The increasing trend of the incidence rate was statistically significant ( P＜0.05). The AAPCs of females aged 25-34, 35-44, 45-54, 55-64, 65-74, and ≥75 years were 2.78% (95% CI: 0.88%-4.72%), 2.20% (95% CI: 0.83%-3.60%), 3.81% (95% CI: 2.45%-5.19%), 4.48% (95% CI: 3.12%-5.85%), 3.79% (95% CI: 2.19%-5.43%), and 2.87% (95% CI: 1.14%-4.63%). The increasing trends of the incidence rates in all age groups were statistically significant ( P＜0.05). The age-period-cohort model showed that the risk of breast cancer increased with age, and people born later were faced with a higher risk of the disease ( P＜0.05). Conclusion:The incidence of breast cancer presented a rising trend in the past fifty years in Qidong. The increasing trend of the incidence rate was statistically significant since the beginning of this century. The health administrative department should formulate preventive and control measures to reduce the burden of breast cancer.
