Objective To analyze survival outcomes and influencing factors among patients with colorectal cancer in Yunnan Province. Methods Clinical data were retrospectively collected from 4 892 patients with colorectal cancer. Survival data were obtained through follow-up. Overall survival (OS) was calculated by using the Kaplan-Meier method. Univariate analysis was performed by applying the log-rank test. Meanwhile, multivariate analysis employed the Cox proportional hazards regression model. Results The 1-, 3-, 5-, and 10-year OS rates for the entire cohort were 91.90%, 74.40%, 64.40%, and 28.70%, respectively. Univariate analysis revealed that age, ethnicity, region, differentiation grade, TNM stage, clinical stage, metastatic status, histological type, and treatment modality (chemotherapy, radiotherapy, and surgery) were associated with patient prognosis (all P<0.05). Multivariate analysis identified age (HR=1.250), region (HR=1.262), differentiation grade (HR=0.761), clinical stage (HR=3.128), and treatment modality (chemotherapy, HR=0.644; radiotherapy, HR=1.605; surgery, HR=0.384) as independent factors affecting survival prognosis in patients with colorectal cancer (all P<0.001). Conclusion Age, region, clinical stage, and treatment modality are independent factors influencing survival among patients with colorectal cancer in Yunnan Province. In clinical practice, these factors should be integrated to develop individualized prevention and treatment strategies, thereby improving patient outcomes.

Objective: To review the relationship between 24 hour movement behaviors and physical and mental health among college students, in order to provide evidence to support health promotion and further research in universities. Methods: Following the Joanna Briggs Institude(JBI) scoping review guidelines, relevant studies published in databases from inception date to December 26, 2025 were searched, including PubMed, Embase, Cochrane Library, Web of Science, China National Knowledge Infrastructure (CNKI) and Wanfang Data. For studies meeting the inclusion and exclusion criteria, a descriptive analysis was conducted to summarize the measurement tools used, adherence rates with guidelines, and the relationship between physical and mental health. Results: A total of 30 studies were included. Measurement tools exhibited a high heterogeneity, with questionnaires being the primary method. The rate of full adherence with 24 hour movement behaviors among college students was less than 30%. Moderate to vigorous physical activity and high quality sleep were associated with improvements in physical fitness, cardiopulmonary function, and mental health, while prolonged sitting was negatively associated with obesity and depression. Equivalent time substitution analysis indicated that increasing moderate to vigorous physical activity and reducing prolonged sitting could significantly improve health outcomes. Conclusions The adherence rate for 24 hour movement behaviors among college students is low and it is closely associated with physical and mental health. Future studies should standardize measurement tools, and implement targeted interventions based on the optimization of daily activity patterns.

ObjectiveTo investigate the correlation between sleep patterns and myopia progression among younger school-age children at a primary school in Changning District of Shanghai, based on the data from the Shanghai Students’ Common Diseases and Health Influencing Factors Monitoring System and a sleep-specific survey, so as to provide data support for myopia prevention and control in this age group. MethodsOne primary school was selected from the common diseases and health influencing factors monitoring system for students in Changning District, Shanghai. A total of 230 first-grade students were included in the study. Myopia and refractive parameters were examined, and sleep patterns were investigated. General demographic characteristics and myopia-related behavior data of the students were also collected. Sleep patterns were evaluated in terms of sleep duration, sleep efficiency, and sleep quality, with the latter assessed using the Chinese version of the Children’s Sleep Habits Questionnaire (CSHQ). Multiple linear regression and binary logistic regression models were used to analyze the association between sleep patterns and myopia progression among these students. ResultsThe results of the regression analyses revealed that the total CSHQ score of the students at baseline survey was (48.85±7.15) points. Their sleep efficiency was (94.49±8.48)%, sleep duration was (9.58±0.93) hours, and the proportion of those with insufficient sleep (<10 hours) was 78.26%. At baseline survey, students’ higher daytime sleepiness scores were associated with lower spherical equivalent (SE) ( β=-0.18, 95%CI: -0.31 to -0.04) and an increased risk of axial length (AL) / corneal radius (CR) ratio >3 (OR=1.52, 95%CI: 1.00 to 2.29), whereas longer sleep duration and higher sleep efficiency were associated with higher SE (β=0.18, 95%CI: 0.05 to 0.32; β=0.17, 95%CI: 0.04 to 0.31, respectively), shorter (AL) (β=-0.15, 95%CI: -0.27 to -0.03; β=-0.13, 95%CI: -0.25 to 0, respectively) and a reduced risk of AL /CR>3 (OR=0.70, 95%CI: 0.51 to 0.96; OR=0.73, 95%CI: 0.53 to 0.99, respectively). At baseline survey, children’s higher propensity for sleep problems (OR=1.70, 95%CI: 1.04 to 2.78), sleep resistance (OR=2.26, 95%CI: 1.36 to 3.75), and sleep anxiety scores (OR=2.15, 95%CI: 1.33 to 3.48) were all associated with an increased risk of AL/CR >3 at follow-up (all P<0.05). Furthermore, higher sleep anxiety scores predicted prolonged AL at follow-up (β=0.03, 95%CI: 0 to 0.05). According to the mixed-effects model, higher daytime sleepiness scores and prolonged sleep duration were independently linked to reduced right-eye SE (β=-0.05, 95%CI: -0.10 to 0, P<0.05) and shorter right-eye AL (β=-0.05, 95%CI: -0.10 to 0, P<0.05). ConclusionIn this school in Shanghai, there are problems of insufficient and poor-quality sleep among young children. Sleep problems such as sleep resistance, delayed sleep onset, sleep anxiety, and daytime sleepiness among children may accelerate the risk of myopia progression, while longer sleep duration and higher sleep efficiency may serve as protective factors against the occurrence and development of myopia.

In recent years, the integration of radiomics and artificial intelligence has brought revolutionary breakthroughs to the precise diagnosis and treatment of kidney tumors. This article systematically reviews the latest advances of radiomics in preoperative diagnosis, surgical planning, evaluation of postoperative prognosis, and prediction of treatment responses. Our findings show that radiomics models based on machine learning and deep learning can effectively distinguish benign and malignant kidney tumors, predict pathological classifications and nuclear gradings, and provide anatomical basis for the development of surgical plans. In addition, the rise of radiogenomics has revealed the association between radiomics features and molecular markers, opening up a new direction for the development of non-invasive biomarkers. However, there are still challenges such as insufficient data standardization, small sample size and model interpretability. In the future, multi-center collaboration can be achieved through federated learning, combined with multimodal data to construct dynamic prediction systems and develop interpretable artificial intelligence technology. This will promote the transformation of radiomics from scientific research to clinical applications, thus achieving precision and individualization of the entire process of diagnosis and treatment of renal tumors.

Objective To explore the association between plasma fibrinogen(FBG)levels and the risk of in-hospital mortality among patients with septic shock.Methods The clinical data of 563 patients diagnosed with septic shock in the Intensive Care Unit(ICU)of Shenzhen Second People's Hospital from August 1,2018,to December 31,2020,were collected.Patient demographic information,basic vital signs,and blood routine and biochemical indices upon admission were gathered.Moreover,the Acute Physiology and Chronic Health Evaluation Ⅱ(APACHEⅡ)scores were calculated.Binary logistic regression analysis was conducted to explore the correlation between plasma fibrinogen levels and in-hospital mortality in patients with septic shock.Additionally,a generalized additive model(GAM)and smoothed curve fitting were employed to investigate the nonlinear relationship between plasma fibrinogen and in-hospital mortality.Receiver operating characteristic(ROC)curves were constructed for FBG and APACHEⅡ scores to predict in-hospital mortality in septic shock patients.The area under the curve(AUC)was computed to compare the predictive efficacies of the two.Furthermore,a segmented linear regression model was utilized for quantification.Results Binary logistic regression analysis demonstrated a significant negative correlation between plasma fibrinogen levels and in-hospital mortality among patients with septic shock(P<0.05).GAM modeling and smoothed curve fitting disclosed a nonlinear association between plasma fibrinogen levels and in-hospital mortality,with an inflection point at 5.54 g/L.The segmented linear regression model indicated that,to the left of the inflection point(FBG≤5.54 g/L),for every 1 g/L decrease in plasma fibrinogen,the risk of death increased by 24.5%(OR=0.755,P=0.003).Conversely,to the right of the inflection point(FBG>5.54 g/L),the relationship was not statistically significant(OR=1.049,P=0.685).The findings of the subgroup analyses indicated that the characteristics of the subgroups did not alter the relationship between blood fibrinogen levels and in-hospital mortality.Conclusion There is a nonlinear relationship between FBG levels and in-hospital mortality in patients with septic shock,which has predictive value for evaluating the risk of in-hospital mortality in this patient cohort.

Idiopathic pulmonary fibrosis （IPF） can be classified as pulmonary collateral disease，and its pathogenesis is mainly characterized by the loss of Qi meridian nourishment，the loss of Yin meridian nourishment，and the formation of blood stasis in the blood vessels. Qi Yin deficiency is the pathological basis that runs through IPF，and obstruction of meridians and collaterals is a key element in the development of the disease. The dysfunction of "spleen being in charge of the defensive function" is closely related to the formation of the pathological pattern of "lung deficiency and collateral stasis" in IPF. The term "spleen being in charge of the defensive function" originated from the Yellow Emperor's Inner Canon. If the spleen is healthy，the Qi will be filled with vitality. Positive energy is stored inside，evil cannot be dried up. Its concept is quite similar to the immune defense function in modern medicine. If the principle of "spleen being in charge of the defensive function" is lost，the key structure and function of the IPF alveolar epithelial barrier may be abnormal，and it can interact with various innate immune cells to promote inflammation and fibrosis processes. Therefore，this article explains the imbalance of immune homeostasis in IPF alveolar epithelium from two aspects：the barrier function of alveolar epithelial cells（AECs） and their interaction with innate immune cells. And based on the theory of "spleen being in charge of the defensive function"，using traditional Chinese medicine for strengthening the spleen and nourishing Qi to treat IPF from the perspective of the spleen. This not only strengthens the scientific connotation of "spleen being in charge of the defensive function" in the pathogenesis of IPF，but also provides new research directions and ideas for its future clinical prevention and treatment.

Detrusor-sphincter dyssynergia (DSD) is a lower urinary tract dysfunction syndrome caused by disorders of the neural regulatory pathways for micturition. Its core feature is that the urethral sphincter fails to relax coordinately during detrusor contraction; instead, the persistent abnormal contraction leads to a series of severe complications such as dysuria, elevated intravesical pressure, and upper urinary tract damage.DSD is common in patients with central nervous system lesions, such as spinal cord injury and multiple sclerosis. This paper systematically reviews the latest research progress on the neural mechanisms of DSD, including ① loss of central regulation and excessive excitation of the spinal cord center, i.e., the loss of supraspinal inhibition leading to sacral spinal reflex hyperactivity; ② imbalance of key neurotransmitters and receptors, involving excessive glutamatergic excitation, weakened gamma-aminobutyric acid ergic/glycinergic inhibition, and the involvement of purinergic and endocannabinoid systems; ③ neuroimmunity and inflammatory response, where the activation of microglia and astrocytes after spinal cord injury releases pro-inflammatory factors, exacerbating neuronal excitability and circuit remodeling; ④ peripheral nerve and gut-bladder axis mechanisms, where sphincter structural remodeling and the gut microbiota-neuroimmunity crosstalk form a vicious cycle. The paper focuses on the sacral Onuf's nucleus as the“core hub”and key therapeutic target of DSD, discussing the central role of its dysfunction in the occurrence of synergistic disorders. In terms of therapeutic strategies, the paper summarizes existing traditional methods, such as drugs, botulinum toxin injection and neuromodulation, and envisions the cutting-edge directions of targeted intervention, such as precise strategies including gene therapy and neurotrophic support, as well as the challenges faced in clinical translation. Finally, the paper discusses the application prospects of precision medicine and artificial intelligence in the diagnosis and treatment of DSD, including precise classification based on multi-omics data, artificial intelligence-assisted recommendation of individualized treatment plans, and the development of dynamic closed-loop regulation systems. This paper aims to provide a theoretical basis and research direction for in-depth understanding of the neural mechanisms of DSD, and to promote the precise diagnosis, treatment and neural function remodeling.

Objective: To delineate the epidemiologic profile of rifampicin resistant pulmonary tuberculosis (RR-PTB) among students in Chongqing, so as to provide evidence for effectively controlling RR-PTB outbreaks in schools. Methods: Individual level surveillance records of 395 student RR-PTB cases reported from 2015 to 2024 were extracted from the China Information System for Disease Control and Prevention. The Joinpoint regression analysis was employed to quantify temporal trends in the registration rate of student RR-PTB cases, and the comparison of RR-PTB registration rates with different demographic characteristics and different regions was performed using Chi-square test. Results: From 2015 to 2024, a total of 395 student RR-PTB cases were identified, with the registration rate ranged from 0.07 per 100 000 to 1.47 per 100 000, showed a fluctuating upward trend ( AAPC= 35.22%, t =4.13, P <0.01). A turning point was detected in 2017, rates rose during 2015-2017 (APC=295.23%， t =4.62， P < 0.01 ) and plateaued thereafter (APC=-0.47%， t =-0.12， P =0.91). The proportion of RR-PTB cases occurring among students increased both among all RR-PTB cases (1.54% in 2015, 7.48% in 2024) and all student pulmonary tuberculosis cases (0.20% in 2015, 7.17% in 2024), with significant linear trends ( χ 2 trend =33.55,159.98, both P <0.01). The majority of cases were enrolled in senior high school (50.38%), classified as retreatment (53.92%), of Han ethnicity (75.95%), and diagnosed with multidrug resistant tuberculosis(53.16%). There were significant differences in the composition of different ethnicity, registration category and resistance pattern between different years( χ 2=23.47, 17.23, 59.64，all P <0.05). The South-Eastern Wuling Mountainous Region exhibited the highest notification rate (3.96 per 100 000), whereas the western region had the lowest rate ( 0.47 per 100 000). County level jurisdictions reported higher rates than district level ones (2.16 per 100 000 vs 0.63 per 100 000 ). Statistically significant differences were observed in the RR-PTB reported rates among students across different districts and counties( χ 2=418.05,167.05,both P <0.01). Conclusions From 2015 to 2024, the registration rate of detected student RR-PTB cases in Chongqing showed an increasing trend. Students have become one of the key populations for drug resistant TB prevention and control. Intensified health education and active case finding should be implemented to enhance proactive surveillance capabilities.

Objective To analyze the epidemiological characteristics and trends of the incidence and mortality of biliary tract cancer in Shanghai from 2002 to 2020. Methods Data on new cases and deaths of malignant tumors of the gallbladder, extrahepatic bile ducts, and other biliary tract organs from 2002 to 2020 were obtained from the Population-based Cancer Registry and Vital Statistics System of Shanghai Municipal Center for Disease Control and Prevention. Cases or deaths, proportion, crude rate, age-specific rate, age-standardized rate (ASR) and others were calculated stratified by year of diagnosis or death, gender and age-group. ASRs were calculated using Segi′s 1960 world standard population. Trends of the annual percent change (APC) of ASRs, age-specific rates and proportions of new cases with selected diagnostic character of biliary tract cancer stratified by different groups were analyzed by Joinpoint analysis software. Results Annual new cases of biliary tract cancer in Shanghai increased from 963 in 2002 to 1 537 in 2020, with ASR of incidence changing from 3.91/10⁵ to 3.59/10⁵. Annual deaths increased from 830 to 1 225, with ASR of mortality decreased from 3.36/10⁵ to 2.69/10⁵. In 2020, the crude rate of incidence of biliary tract cancer was 10.43/10⁵ (9.54/10⁵ in males and 11.30/10⁵ in females) in Shanghai, and the ASR was 3.59/10⁵ (3.54/10⁵ in males and 3.61/10⁵ in females), with no statistically significant gender difference (P=0.731). The crude rate of mortality was 8.31/10⁵ (7.60/10⁵ in males and 9.00/10⁵ in females), and the ASR was 2.69/10⁵ (2.69/10⁵ in males and 2.66/10⁵ in females), also with no significant gender difference (P=0.874). Age-specific nunbers and rates of incidence and mortality generally increased with aging. Stratified by gender, the trend of ASRs of incidence of biliary tract cancer in Shanghai in males showed no significant change (P=0.179) from 2002 to 2020, nor did that of ASRs of mortality (P=0.738). In females, the ASRs of incidence decreased at an average annual rate of 1.58% (P<0.001), while the trend of ASRs of mortality showed no significant change from 2002 to 2011 (P=0.774), but ASRs decreased at an average annual rate of 3.72% from 2011 to 2020 (P<0.001). Among new cases, the proportions of morphological verification increased, while the proportions of imaging verification decreased. The gallbladder was the most common site, but its proportions decreased significantly, whereas the proportions of extrahepatic bile duct increased from 25.75% to 42.88%. Over 60% of cases were unknown stage at diagnosis, while the combined proportions of stages Ⅰ-Ⅲ remained less than that of stage Ⅳ. Conclusions The ASRs for incidence and mortality of biliary tract cancer in Shanghai remain relatively high, with distinct epidemiological characteristics. The improvement in the diagnosis and treatment of biliary diseases maybe have impact on the incidence patterns of biliary tract cancer in Shanghai, but the effect on increasing survival rates and reducing mortality rates is relatively lagging. It needs a big progress to advance the screening, diagnosis, and survival of biliary tract cancer in Shanghai. This study provides a foundation for further research and prevention strategies for biliary tract cancer.

Objective:To observe the effectiveness and safety of different doses of esketamine combined with propofol for intravenous administration in the child patients undergoing enhanced computed tomography(CT)examination,and to clarify the optimal clinical dose of esketamine in combination with propofol for sedation.Methods:This study is a randomized,controlled,double-blind(blinded to subjects and evaluators),and single-center clinical trial.A total of 120 preschool children undergoing enhanced CT examination were randomly divided into propofol group(P group),propofol+0.3 mg·kg-1 esketamine group(P+K3 group),and propofol+0.5 mg·kg-1 esketamine group(P+K5 group),and there were 40 cases in each group.All the children were given 2mg·kg-1 propofol,and additional propofol was administered in increments of 1 mng·kg-1 until the sedation criteria for entering the CT room were met[Modified Observer's Assessment of Alertness/Sedation(MOAA/S)score ≤3].The vital signs of the children were observed and recorded at four time points:before sedation(T0),when sedation was satisfactory(T1),during contrast agent injection(T2),and upon awakening(T3).The examination time,time to satisfactory sedation(from the start of sedation to MOAA/S score≤3),and awakening time(from the end of the examination to MOAA/S score＞4)of the children in various groups were recorded.The total dose of propofol and the proportion of cases requiring additional propofol were compared among various groups.Adverse reactions during induction,examination,and after awakening were also compared among various groups.Results:There were no significant differences in general conditions of the children in three groups(P＞0.05).Hemodynamic parameters:at T2,compared with P group,the SpO2 levels of the children in P+K3 group and P+K5 group were increased(P＜0.05);at T1,compared with P group,the SBP levels of the children in P+K3 group and P+K5 group were increased(P＜0.05).There were no significant differences in examination time of the children in three groups(P＞0.05).Compared with P group and P+K3 group,the time to satisfactory sedation of the children in P+K5 group was shorter(P＜0.05).Compared with P group,the awakening time of the children in P+K3 group and P+K5 group was shorter(P＜0.05).Compared with P group and P+K3 group,the total dose of propofol of the children in P+K5 group was decreased(P＜0.05),and the proportion of cases requiring additional propofol was lower(P＜0.05).Adverse reaction indicators:compared with P group,the incidence of respiratory depression of the children in P+K3 group and P+K5 group was lower(P＜0.05),and the incidence of nausea and vomiting was lower(P＜0.05).Compared with P group and P+K3 group,the incidence of movement during the examination of the children in P+K5 group was lower(P＜0.05),and the incidence of dizziness was higher(P＜0.05).There were no significant differences in the incidence of increased airway secretions of the children in three groups(P＞0.05).Conclusion:The use of 0.5 mg·kg-1 esketamine combined with 2 mg·kg-1 propofol for intravenous administration in the child patients for enhanced CT examination sedation can improve the efficiency of such examinations and offers high safety and effectiveness.
