Background Lung cancer, one of the most common malignant tumors worldwide, has long ranked first in cancer incidence and mortality, posing a severe challenge to public health systems. Objective To analyze the trends in incidence, mortality, and disability-adjusted life years (DALYs) of lung cancer among residents in Jing'an District, Shanghai, from 2002 to 2021, explore the impacts of population aging, population growth, and age-specific prevalence on disease burden, and provide a scientific basis for optimizing regional lung cancer prevention and control strategies. Methods Based on the cancer registration and cause-of-death surveillance data of registered residents in Jing'an District, Shanghai, from 2002 to 2021, Joinpoint regression models were used to analyze the annual change trends (APC) and average annual change trends (AAPC) of lung cancer incidence, mortality, DALY rate, and their age-standardized rates. Decomposition analysis was applied to quantify the contribution of population aging, population growth, and age-specific prevalence to changes in the number of new cases, deaths, and DALYs. Results From 2002 to 2021, the crude incidence rate of lung cancer in Jing'an District increased from 68.00 per 100000 to 144.36 per 100000 (AAPC=4.86%, P<0.001), and the age-standardized incidence rate rose from 43.09 per 100000 to 61.46 per 100000 (AAPC=2.89%, P<0.001). The growth rate of incidence was significantly higher in females (AAPC=6.73%) than in males (AAPC=3.62%). The crude mortality rate increased from 58.08 per 100000 to 66.11 per 100000 (AAPC=1.10%, P<0.001), while the age-standardized mortality rate decreased (AAPC=−1.54%, P<0.001). The crude DALY rate showed an upward trend (AAPC=0.94%, P=0.002), whereas the age-standardized DALY rate declined (AAPC=−1.63%, P<0.001). Significant differences were observed across genders and age groups: the mortality and DALY rates increased in males aged 60-64 years, while the fastest incidence growth occurred in females aged 45-64 years. The results of decomposition analysis indicated that the increase in new cases was primarily attributed to age-specific incidence (38.15%) and aging (37.31%); the growth in deaths and DALYs was driven by aging, while age-specific mortality and population growth showed offsetting effects. From 2002 to 2021, the probability of premature death from lung cancer among males (2.04%-2.52%) in Jing'an District showed no statistically significant trend (AAPC=−0.28%, P=0.440), while it presented a decreasing trend in the total population (1.37%-1.89%) and females (0.72%-1.26%) (AAPC=−0.80% and −2.23%, respectively; P=0.029 and <0.001, respectively). Conclusion From 2002 to 2021, the risk of lung cancer incidence in Jing’an District, Shanghai, continue to increase, with a disease burden exhibiting significant heterogeneity by gender and age: key features include a rapid increase in new cases and a trend toward younger onset among females, alongside rising mortality risk among males aged 60–64 years. Population aging and increasing age-specific incidence rates are primary drivers of the growing number of cases, while declining age-specific mortality rates mitigate the rise in mortality burden.

Objective:To explore the relationship between trait mindfulness and nomophobia in middle school students.Methods:A total of 942 middle school students were selected to use the Mindfulness Attention Awareness Scale and the Nomophobia Scale for Chinese for two data collection intervals of 12 months(T1 and T2,respective-ly).Results:The MAAS scores were higher at T1 than at T2(P＜0.001).The simultaneous(r=-0.11,-0.21,Ps＜0.01)and sequential(r=-0.14,-0.15,Ps＜0.001)correlations between MAAS scores and NSC scores were significant.The MAAS scores at T1 negatively predicted the NSC scores at T2(β=-0.09),and the NSC scores at T1 also negatively predicted the MAAS scores at T2(β=-0.10).Conclusion:It suggests that trait mind-fulness and nomophobia could predict each other in middle school students.

Objective To explore the effectiveness of a hospital-to-home transitional health management program for caregivers of children with severe encephalitis,aiming to provide a reference for optimizing transitional care models for these patients.Methods A convenience sampling method was used to select 84 children with severe encephalitis and their caregivers admitted to the neurology department of a tertiary hospital in Zhengzhou between March 2023 and June 2024.According to the admission time,they were divided into an experimental group and a control group,with 42 cases in each group.The experimental group received a hospital-to-home transitional health management program in addition to routine care,while the control group received standard care and discharge instructions.Differences in caregivers' perceived benefits,caregiver burden,disease management ability,and post-intervention outcomes of the children were compared between the 2 groups before and after the intervention.Results All 42 participants in both groups completed the study.After the intervention,the experimental group reported higher perceived benefits of(91.29±9.76)compared to(84.81±12.86)in the control group,lower caregiver burden of(48.55±7.15)compared to(54.71±11.23)in the control group,greater disease management ability of(41.83±4.97)than(37.79±5.23)in the control group,and lower difficulty in disease management of(31.52±7.82)compared to(34.55±3.96)in the control group,with all differences being statistically significant(P＜0.05).No statistically significant difference was found in the prognosis of the children between the 2 groups(P=0.500).Conclusion The hospital-to-home transitional health management program can effectively enhance caregivers'perceived benefits and disease management capabilities,reduce their caregiving burden,and provide scientific evidence for optimizing transitional care for children with severe encephalitis.

Objective:To investigate the correlation of color Doppler flow imaging (CDFI) and shear wave elastography (SWE) with pathological classification and prognosis of breast cancer patients.Methods:A total of 87 patients (103 lesions) with breast cancer admitted to Shanxi Maternal and Child Health Care Hospital and the Second Hospital of Shanxi Medical University From May. 2021 to Mar. 2024 were retrospectively included. All patients underwent CDFI and SWE examinations before surgery. The pathological characteristics and molecular typing of each lesion were recorded, and the correlation of CDFI and SWE examination parameters with molecular typing of breast cancer was evaluated. Patients were followed up for 1 year, and the predictive value of CDFI and SWE parameters in lymph node metastasis was analyzed by receiver operating characteristic curve (ROC) .Results:There were no statistically significant differences in the pulse index (PI) , resistance index (RI) , maximum lesion elastic modulus (E max) , and the ratio between the elastic value at the hardest lesion and the elastic value of adipose tissue (E ratio) among patients with different pathological types ( F=0.64, 0.13, 0.81, 2.84, P>0.05) . There were no statistically significant differences in PI and RI values among patients with different tumor sizes ( F=2.99, 1.81, P>0.05) , and statistically significant differences in E max and E ratio among patients with different tumor sizes ( F=6.42, 34.31, P<0.05) . The differences among different molecular types PI, RI, E max, and E ratio were statistically significant ( F=406.59, 245.23, 206.30, 204.36, P<0.05) , and Luminal B type PI, RI, E max, and E ratio were the highest, followed by HER2-positive, triple-negative, and Luminal A type, with statistically significant differences ( P<0.05) . PI, RI, E max and E ratio in patients with positive lymph node metastasis were higher than those in patients with negative lymph node metastasis ( t=4.99, 3.04, 2.70, 3.13, all P<0.05) . ROC results showed that the area under the curve (AUC) of PI, RI, E max and E ratio for predicting lymph node metastasis of breast cancer were 0.654, 0.704, 0.664 and 0.696, respectively. The sensitivity to predict lymph node metastasis of breast cancer was 74.19%, 54.84%, 51.61%, 64.52, and the specificity was 54.17%, 79.17%, 79.17%, 70.83% (all P<0.05) . Conclusions:The correlation of CDFI and SWE examination parameters are correlated with the molecular classification of breast cancer, and the prediction of lymph node metastasis of breast cancer is good.

Objective:To assess the effectiveness of combining color Doppler ultrasound (CDU) with shear wave elastography (SWE) in forecasting the likelihood of breast cancer (BC) recurrence.Methods:From Jan. 2022 to Jan. 2024, we gathered data on 92 BC patients admitted to Shanxi Maternal and Child Health Hospital and Shanxi Cancer Hospital, focusing on their lesion characteristics. Each patient underwent CDU and SWE examinations pre-surgery and was monitored for a year. Based on BC recurrence, patients were categorized into recurrence and non-recurrence groups. We compared CDU imaging and hemodynamic features of BC between these groups and evaluated SWE elastic modulus values. To assess the agreement between CDU, SWE, and their combined use in predicting BC recurrence and pathological diagnosis, we employed the Kappa test. Additionally, we plotted ROC curves to analyze the predictive power of CDU, SWE, and their combination in assessing BC recurrence risk. Results:Among the 92 BC patients studied, 38 experienced recurrence, while 54 did not. CDU examination revealed that the non-recurrence group exhibited significantly larger tumor maximum diameter, higher peak systolic velocity (PSV), a higher proportion of aspect ratio ≥ 1, irregular margins, calcification, and increased vascular abundance, compared to the recurrence group ( t/ χ2=17.188, 18.491, 6.099, 15.374, 14.526, 19.318, P<0.05). Additionally, the vascular resistance index (RI) was lower in the non-recurrence group ( t=-26.429, P<0.05). SWE results indicated that the recurrence group had higher average (E mean), maximum (E max), and minimum (E min) elastic moduli compared to the non-recurrence group ( t=14.39, 12.34, 8.29, P<0.05). CDU and SWE predictions showed substantial agreement with pathological results, with Kappa values of 0.66 and 0.69, respectively ( P<0.05). The combination of CDU and SWE predictions demonstrated excellent concordance with pathological outcomes ( Kappa=0.91, P<0.05). In terms of predicting BC recurrence risk, CDU and SWE had accuracies of 83.70% and 84.21%, respectively. The ROC curve analysis showed AUC values of 0.830 for CDU, 0.847 for SWE, and 0.955 for their combination. Sensitivity was 0.870 for CDU, 0.852 for SWE, and 0.963 for the combination. Specificity was 0.789 for CDU, 0.842 for SWE, and 0.947 for the combination. Positive predictive values were 78.95% for CDU, 84.21% for SWE, and 94.74% for the combination, while negative predictive values were 87.04% for CDU, 85.19% for SWE, and 96.30% for the combination. The AUC for CDU in predicting post-operative BC recurrence risk was not significantly different from SWE ( χ2=0.04, P>0.05), but the combined prediction AUC was significantly higher than individual predictions ( χ2=8.00, 7.04, P<0.05) . Conclusion:The predictive value of CDU and SWE combined examination for the recurrence risk of BC is better than that of single examination, and it is suggested that the combined examination method should be popularized in clinic.

Opium is obtained by air-drying the milky latex extracted from the unripe capsules of the opium poppy(Papaver somniferum).This latex is rich in benzylisoquinoline alkaloids(BIA),with major active compounds in-cluding morphine,codeine,thebaine,papaverine,and noscapine.Compound licorice oral solution and compound licorice tablets are derivative drugs containing opium.Initially classified as over-the-counter(OTC)medications,both formulations were later reclassified as prescription drugs by the National Medical Products Administration(NMPA),restricting their purchase without proper authorization.Although the national pharmacopeia standards specify the morphine content in the opium raw materials used for compound licorice oral solution and tablets,they lack mandatory requirements for the detection and quantification of the other four major alkaloids.Given the unique nature of opium raw materials and the stringent regulatory requirements for such drugs,it is imperative to enhance and refine simultaneous detection and control methods for all alkaloid components in these products.Furthermore,the establishment of scientific and reasonable detection and control standards for preservatives in compound licorice formulations is crucial to improving overall product quality management and ensuring drug safety and efficacy.This study analyzes and discusses the quality standards,detection methods,and research progress for opium and com-pound licorice preparations,aiming to explore the potential for technological innovation and ensure the safe use of these medications.

Objective To develop a novel solid-phase extraction(SPE)method based on a functionalized nanofiber membrane for the efficient co-extraction of structurally diverse antibiotics with markedly different physico-chemical properties from source water,and to establish a high-throughput analysis method by coupling this technique with ultra-performance liquid chromatography-tandem mass spectrometry(UPLC-MS/MS).Methods A polydopamine and zirconium(Ⅳ)fumarate metal-organic frameworks(MOF-801)co-modified polyacrylonitrile nanofiber membrane(PDA@PAN/MOF-801 NFMs)was prepared as the SPE adsorbent through hybrid electrospinning and dopamine self-polymerization.Critical SPE and UPLC-MS/MS parameters were optimized,and the method was applied to analyze antibiotic contamination in source water samples from 14 sources of centralized drinking water supply in Suzhou,China,to evaluate the practical application potential of the method.Results The PDA@PAN/MOF-801 NFMs adsorbent demonstrated efficient adsorption of 32 antibiotics from 6 classes through multiple retention mechanisms,including synergistic electrostatic interactions,hydrogen bonding,and π-π interactions.In combination with UPLC-MS/MS,the SPE method we developed enabled high-throughput detection of multiple antibiotics in source water,with limits of detection(LOD)being 0.001-0.05 ng/L and limits of quantitation(LOQ)being 0.005-500 ng/L.Spiked recoveries were 70.14%-111.50%.Intra-day relative standard deviation(RSD)was below 14.12%and the inter-day RSD was below 15.07%.The method demonstrated excellent sensitivity,accuracy,and precision.Conclusion In this study,we successfully developed an efficient analytical method based on a novel nanofiber membrane adsorbent.This approach provides a new technical reference for the high-throughput detection of multiple antibiotics in environmental waters and shows promising potential for practical applications.

Objective:To investigate the incidence of osteoporosis (OP) in maintenance hemodialysis (MHD) patients at the blood purification center in Gaochun district, and analyze its influencing factors.Methods:A retrospective study was conducted on 3 622 patients who received regular MHD treatment at Nanjing Gaochun People′s Hospital and Nanjing Gaochun Traditional Chinese Medicine Hospital from January 2019 to December 2023. The demographic characteristics, comorbidities, and clinical data such as blood calcium and creatinine of patients were collected. The ultivariate Logistic regression model was applied to analyze the influencing factors of OP in MHD patients.Results:The survey revealed that 33.63% of MHD patients had decreased bone mass, and 37.24% of MHD patients experienced osteoporosis. According to the occurrence of OP, 3 622 patients were separated into the OP group (1 349 cases) and the non-OP group (2 273 cases). Univariate analysis showed that compared with the non-OP group, the albumin (ALB) level in the OP group was lower: (38.95 ± 5.17) g/L vs. (40.32 ± 5.84) g/L, there was statistical difference( P<0.05). Compared with the non-OP group, the levels of immunoreactive parathyroid hormone (iPTH) and alkaline phosphatase (ALP) in the OP group were higher: (262.29 ± 36.76) ng/L vs. (249.55 ± 32.73) ng/L, (114.74 ± 18.01) U/L vs. (109.63 ± 17.25) U/L, the proportion of patients aged≥60 years old, female and dialysis duration≥5 years was higher: 61.75%(833/1 349) vs. 47.87%(1 088/2 273), 66.35%(895/1 349) vs. 54.86%(1 247/2 273), 52.34%(706/1 349) vs. 34.36%(781/2 273), there were statistical differences( P<0.05). Multivariate Logistic regression revealed ALB ( OR = 0.724, 95% CI 0.568 - 0.920), iPTH ( OR = 1.374, 95% CI 1.095 - 1.725), ALP ( OR = 1.325, 95% CI 1.070 - 1.641), age ( OR = 2.753, 95% CI 1.664 - 4.556), gender ( OR = 2.993, 95% CI 1.611 - 5.560), and dialysis time ( OR = 4.216, 95% CI 2.365 - 7.516) were all influencing factors for the occurrence of OP in MHD patients ( P<0.05). Conclusions:The incidence of OP in MHD patients in Gaochun district is high, and its occurrence is closely related to ALB, iPTH, ALP, age, gender and dialysis time. Clinical attention should be focused on this.
