Objective:To explore the diagnostic value of blood flow parameters of carotid ultrasound combined with serum Sortilin and paraoxonase-1 (PON-1) for stability of carotid atherosclerotic plaque (CAP). Methods:A total of 100 CAP patients who admitted to Rugao Hospital of Traditional Chinese Medicine from January 2021 to December 2023 were selected,and they were divided into a stable plaque group (n=54) and a unstable plaque group (n=46). Enzyme linked immunosorbent assay (ELISA) was adopted to determine the expression levels of serum Sortilin and PON-1 of patients in two groups. Multi factor logistic regression was implemented to analyze the influencing factors on CAP stability. The receiver operating characteristic (ROC) curves were drawn to analyze the diagnostic efficiency of blood flow parameters of carotid ultrasound combined with Sortilin and PON-1 on CAP stability. Results:Compared with the end diastolic blood flow velocity (EDV) and intima-media thickness (IMT) of stable plaque group,unstable plaque group showed increased EDV and IMT,and decreased PSV,and the differences were significant (t=7.536,4.680,5.487,P<0.05),respectively. Compared with stable plaque group,the serum Sortilin level in unstable plaque group significantly increased,while the PON-1 level significantly decreased,and the differences of them were significant (t=8.362,5.581,P<0.05),respectively. Multivariate logistic analysis found that Sortilin was a risk factor that affected CAP stability (OR=3.165,P<0.05),while PON-1 was a protective factor that affected CAP stability (OR=0.765,P<0.05). ROC curve analysis indicated that the area under curve (AUC) values of single Sortilin,PON-1,EDV,IMT,PSV,and the combination of them were respectively 0.788 (95％CI:0.695-0.864),0.814 (95％CI:0.724-0.885),0.847 (95％ CI:0.761-0.911),0.767 (95％ CI:0.672-0.846),0.707 (95％ CI:0.607-0.793) and 0.963 (95％ CI:0.839-0.907). The AUC value of the combination of above 5 indicators was highest,which was better than that of each single indicator,and its sensitivity and specificity were respectively 95.65％ and 83.33％. Conclusion:The EDV,IMT and PSV of blood flow parameters of ultrasound can provide CAP information of morphology and hemodynamics,and serum Sortilin level and PON-1 level can reflect the biological processes of formation and development of CAP. The combined detection of the five indicators can better diagnose CAP stability.

Ultra-high dose-rate (FLASH) radiotherapy is a new mode of radiotherapy that can control tumors while significantly reducing damage to surrounding normal tissues. Since its official naming in 2014, FLASH radiotherapy research has continued to grow, and in 2019 it entered a period of exponential development. Studies have shown that electrons, photons, and protons can all induce the FLASH effect, but the proton beam can overcome the physical limitations of shallow incident depth and high penetration dose, which is considered to be the most effective solution. This article summarizes previous research results of FLASH proton therapy from the research at the cell, animal and clinical levels, and summarizes the hypothesis of the FLASH effect mechanism, aiming to provide reference for promoting the research and clinical transformation of FLASH proton therapy.

Objective:To compare the relative proportion of direct action (ray particles directly destroy biological molecules such as DNA and indirect action (radical-mediated oxidative damage) in the damage caused by X-ray and proton irradiation of lung cancer cells.Methods:Unirradiated human lung adenocarcinoma A549 cells and human large cell lung cancer NCI-H460 cells were cultured in media containing 0, 0.125, 0.25, 0.5, 0.75 mol/L dimethyl sulfoxide (DMSO) for 1 h to obtain plating efficiency (PE) values, thereby determining whether DMSO affected cell survival. Following pretreatment with each DMSO concentration, cells were exposed to X-ray irradiation at physical doses of 2, 4, 6, 8 Gy and proton irradiation at equivalent doses of 2, 4, 6, 8 GyE, respectively. Survival fractions (SF) and maximum protection (MP) values were calculated to evaluate the effects of varying DMSO concentrations on post-irradiation cell survival and to quantify the contribution of indirect radiation damage mechanisms (higher MP indicates greater indirect effect contribution). PE, SF, and MP values were determined using clonogenic assays. Comparisons among multiple groups were performed using one-way ANOVA followed by Tukey's multiple comparison, and comparisons between irradiation groups were analyzed using independent samples t-tests. Results:The PE of unirradiated cells treated with varying DMSO concentrations showed no statistically significant differences. Following pretreatment at different DMSO concentrations and subsequent irradiation with X-rays or protons, the protective effect of DMSO reached saturation at 0.5 mol/L. At this concentration, comparison of the average MP values across 4 radiation doses revealed: In A549 cells, the MP value was 54.21%±1.73% for X-ray irradiation group and 39.69%±0.72% for proton irradiation group ( t=16.82, P<0.001); in NCI-H460 cells, the MP value was 52.04%±1.00% for X-ray irradiation group and 41.31%±0.70% for proton irradiation group ( t=10.19, P<0.001). Conclusions:Under biologically equivalent doses, proton irradiation demonstrates greater reliance on direct effects in lung cancer cells killing compared with X-ray irradiation.

Objective:To analyze the infection status and influencing factors of Helicobacter pylori ( Hp) in healthy children. Methods:This is a cross-sectional study. The data of 684 children aged 3 to 14 years who underwent the 13C urea breath test in the Health Management Center of Fuwai Central China Cardiovascular Hospital from December 2022 to December 2023 were retrospectively collected, and 652 of them who met the criteria were included in the analysis. According to whether they were infected with Hp, the children were divided into the infected group and the non-infected group, and the differences in age, gender, living habits and other aspects between the two groups were compared. Multivariate logistic regression analysis was used to analyze the factors influencing Hp infection. Results:Among the 652 children, there were 134 cases in the infected group and 518 cases in the non-infected group, with an Hp infection rate of 20.6%. The Hp infection rate showed an upward tendency with age. The Hp infection rates in children aged 3 to 5 years, 6 to 11 years, and 12 to 14 years were 12.6%, 22.0%, and 25.2% respectively ( χ 2=9.862, P=0.007). Univariate analysis showed that the proportions of Hp infection were higher in children who never washed their hands, ate in school cafeterias, did not have separate meals, were fed with chewed food, bit their fingers or toys, lived with relatives who had a history of gastrointestinal diseases, had low family income, had parents with low educational level, and were mixed/artificially fed during infancy, which were 26.1%, 24.1%, 25.4%, 25.7%, 26.0%, 25.8%, 25.1%, 23.7%, and 23.6% respectively (all P<0.05). Multivariate analysis showed that separate meals, good handwashing habits, and high family income were protective factors against Hp infection ( OR=0.689, 0.779, 0.602, P=0.004, 0.013, 0.019), while feeding with chewed food was a risk factor for Hp infection ( OR=1.998, P=0.001). Conclusion:The Hp infection rate of children undergoing health examination in Zhengzhou is at low level, and the main influencing factors are separate meals, handwashing habits, feeding with chewed food, and family income.

Objective:To analyze the correlation between poor sleep status in late pregnancy and postpartum depression and anxiety.Methods:In this prospective cohort study, a total of 401 women in early pregnancy were consecutively enrolled at Beijing Tian Tan Hospital, Capital Medical University, from December 2020 to April 2021. The Pittsburgh Sleep Quality Index (PSQI) and the Epworth Sleepiness Scale (ESS) were used to assess the sleep status in late pregnancy. The Edinburgh Postnatal Depression Scale (EPDS) and the 7-item Generalized Anxiety Disorder Scale (GAD-7) were used to assess the emotional status in late pregnancy and 6 weeks after delivery. During the follow-up, 123 subjects did not complete the sleep and emotional assessment in late pregnancy, 77 subjects did not complete the postpartum emotional assessment, and 201 cases were finally included in the study. Multivariate logistic regression analysis was used to analyze the correlation between poor sleep status in late pregnancy and postpartum depression and anxiety.Results:Among 201 women in early pregnancy included in the analysis, the detection rate of postpartum depression and anxiety was 15.4% (31/201) and 27.4% (55/201), respectively. Poor sleep quality ( OR=2.49, 95% CI: 1.02-6.07), difficulty falling asleep ( OR=6.74, 95% CI: 2.31-19.70), and excessive daytime sleepiness ( OR=6.34, 95% CI: 2.08-19.32) in late pregnancy were positively correlated with postpartum depression (all P0.05). Poor sleep quality ( OR=3.89, 95% CI: 1.81-8.40), difficulty falling asleep ( OR=6.75, 95% CI: 2.43-18.77), short-time sleep ( OR=2.89, 95% CI: 1.36-6.11), fragmented sleep ( OR=5.69, 95% CI: 2.27-14.28) and excessive daytime sleepiness ( OR=3.07, 95% CI: 1.07-8.78) in late pregnancy were positive correlation factors for postpartum anxiety (all P0.05). Conclusions:Poor sleep status in late pregnancy is associated with postpartum depression and anxiety. Strengthening screening and management of poor sleep status in late pregnancy may help maintain healthy postpartum emotion.

Objective:To systematically evaluate the impact of internet-based patient decision aid (PtDA) on decision-making for prenatal screening and diagnosis among pregnant women.Methods:Randomized controlled trials (RCTs) on the application of internet-based PtDA for prenatal screening and diagnosis among pregnant women were searched in PubMed, Embase, Web of Science, CINAHL, Cochrane Library, China National Knowledge Infrastructure, Wanfang Date, VIP, and China Biology Medicine disc. The search period was from inception to August 11, 2024. Two researchers independently screened the literature, extracted data, and assessed the quality of included studies. Meta-analysis was performed using RevMan 5.4 software.Results:A total of 10 studies involving 3 838 pregnant women were included. The meta-analysis showed that internet-based PtDA significantly reduced decision conflict ( P<0.05), improved decision knowledge ( P<0.01), and decreased decision anxiety ( P<0.05) among pregnant women but had no significant impact on decision regret ( P>0.05) . Conclusions:Internet-based PtDA effectively reduce decision conflict and anxiety while improving decision knowledge during prenatal screening and diagnostic decision-making. Future studies should focus on developing culturally appropriate decision aids tailored to the Chinese context and explore the enhanced role of nurses in prenatal screening counseling.
