Objective To investigate correlations of dynamic changes in serum C-reactive pro-tein(CRP),procalcitonin(PCT),and neutrophil-to-lymphocyte ratio(NLR)before and after symptomatic treatment with prognosis of neonates with neonatal respiratory distress syndrome(NRDS)of different etiologies.Methods A total of 110 premature infants were selected as study subjects and divided into neonatal infection group(group A)and fetal intrauterine distress group(group B)based on different causes of NRDS.Additionally,30 neonates with NRDS caused solely by prematurity were selected as control group.Serum CRP and PCT levels and NLR were compared among the three groups before and after treatment.Results There were statistically significant differences in oxygen therapy duration,ventilation duration,the proportion of infants requiring re-intubation,hospital stay,and the number of apnea episodes among three groups(P＜0.006).Before treatment,there was no sta-tistically significant difference in serum CRP levels between group A and group B(P＞0.05).Ser-um CRP levels in group B were higher than those in the control group.Moreover,serum PCT levels was lower than the group A,and NLR in the group B were higher than those in the group A and the control group.CRP,PCT levels,and NLR in the group A were higher than those in the control group(P＜0.05 or P＜0.006).After treatment,serum CRP levels in all three groups decreased compared to before treatment.Serum PCT levels in the group A decreased compared to before treat-ment.NLR in both group A and group B decreased compared to before treatment,with statistically significant differences(P＜0.006).There were statistically significant differences in serum CRP and PCT levels between the group A and the control group after treatment(P＜0.006).After treat-ment,there was a statistically significant difference in serum CRP levels between the group B and the control group(P＜0.006),but no statistically significant differences in PCT levels and NLR(P＞0.05).Compared with group A,there was a statistically significant difference in PCT levels in the group B(P＜0.006).Multivariate Logistic regression results showed that CRP,PCT,and NLR were independent influencing factors for the prognosis of infants in the group A.The receiver operat-ing characteristic curve analysis results showed that the areas under the curve(AUC)after treatment for serum CRP,PCT,and NLR alone in predicting prognosis in the group A were 0.789,0.738,and 0.758,respectively,and the AUC for combined prediction was 0.934.In the group B,the AUC for serum CRP,PCT,and NLR alone in predicting prognosis after treatment were 0.719,0.772,and 0.768,respectively,and the AUC for combined prediction was 0.886.The sensitivity and specificity of combined prediction in both groups were higher than those of each indicator alone,and the predictive value of their combined detection for the prognosis of premature infants in group A was higher than that in the group B.Conclusion There are differences in PCT levels and NLR before treatment among neonates with NRDS of different etiologies.After symptomatic treatment,CRP,PCT levels and NLR decrease in all three groups,indicating a good prognosis.

Objective To explore the interaction mechanisms among different dimensions of online learning competence in undergraduates,providing scientific evidence for optimizing software design and online education strategies.Methods A cross-sectional study was conducted with 347 undergraduates from Kunming Medical University via an online questionnaire in October 2024.Reliability testing and exploratory factor analysis were performed using SPSS 26.0,while structural equation modeling was constructed with Amos 24.0.Results Driving force directly and positively influenced regulatory force(β=0.778,P<0.001)and reciprocal force(β=0.302,P=0.003),but had no significant direct effect on adaptive force(β=0.131,P=0.182).Regulatory force and reciprocal force both exerted direct positive effects on adaptive force(β=0.262,P=0.022;β=0.410,P<0.001).The indirect effect of driving force on adaptive force accounted for 78.1%of the total effect(P=0.007),with regulatory force showing a significant mediating role(β=0.178,P=0.023),while reciprocal force alone did not(β=0.108,P=0.060).A chain mediating effect(driving force→regulatory force→reciprocal force→adaptive force)was confirmed(β=0.124,P=0.004).Conclusion Driving force serves as the core of online learning competence,and adaptive capacity is enhanced through regulatory and reciprocal forces.To promote knowledge internalization and adaptability,it is required to optimize feedback mechanisms and deepen interactive designs in online learning platforms.

Objective:To determine the incidence of adrenal incidentalomas(AIs) in patients with diabetes mellitus and the metabolism profiles.Methods:A total of 615 hospitalized patients with diabetes mellitus in the Department of Endocrinology and Metabolism of Peking University People′s Hospital from March 2020 to May 2021 were retrospectively included in this study. AIs were screened by unenhanced chest computed tomography(CT) retrospectively and subsequently confirmed by multiplanar reconstruction. Participants′ physical indicators, metabolic profiles, and adrenal function parameters were collected. Unpaired t test, Mann-Whitney U test, and Chi-Square test were adopted to compare the metabolism profiles between diabetes mellitus patients with or without AIs. Regression models were used to estimate the correlations between AIs and the metabolism profiles such as blood glucose, blood lipids, blood pressure, and the adrenal function parameters.Results:Twenty-seven out of 615 participants were detected with AIs(4.4%). Patients with AIs had higher body mass index, waist circumference, and hip circumference than patients without AIs [(29.4±5.1)kg/m 2vs(26.8±3.8)kg/m 2,P=0.018; (102.3±11.7)cm vs(95.8±10.3)cm, P=0.002; (107.3±10.1)cm vs(101.4±7.6)cm, P=0.008]. The levels of serum uric acid and urinary albumin/creatinine ratio were also significantly increased in patients with AIs [(409.6±118.1)μmol/L vs(357.4±100.6)μmol/L, P=0.009; 21.25(7.49, 180.24)mg/g vs 8.60(4.71, 34.56)mg/g, P=0.010]. Besides, individuals with AIs were also associated with a higher risk of co-existing hypertension( P=0.045). Conclusion:The incidence of AIs in patients with diabetes is 4.4%. The presence of AIs in patients with diabetes may associated with increased risk of obesity and hypertension.

Objective Ultra-performance liquid chromatography-quadrupole time-of-flight mass spectrometry(UPLC-Q-TOF-MS)and network pharmacology technology combined with pharmacodynamic experiments were used to analyze the quality markers(Q-markers)in Saorilao Qingfei Zhike Capsules.Methods Using UPLC-Q-TOF-MS technology,the chemical components in different polar extracts of Saorilao Qingfei Zhike Capsules was analyzed.Potential pharmacological components were screened by using antitussive and expectorant models.The"components-targets-diseases"network was constructed and potential Q-markers were screened by network pharmacology technology.Then we conducted pharmacodynamic validation to confirm the Q-markers,which have antitussive and expectorant effects in Saorilao Qingfei Zhike Capsules.Results A total of 120 compounds were obtained from the Saorilao Qingfei Zhike Capsules through qualitative analysis.Among the extracts of different polarity,44 compounds were derived from petroleum ether extract,85 compounds were derived from ethyl acetate extract,79 compounds were derived from n-butanol extract,and 71 compounds were derived from water extract.The results of pharmacological experiments showed that among extracts of different polarity,petroleum ether extract had the best antitussive effect,while n-butanol extract had the best expectorant effect.Three core components for eliminating phlegm and relieving cough were screened through network pharmacology techniques:farcalinol,farcalinediol,and rubimaillin.Pharmacodynamic studies verified that all core components mentioned above have certain antitussive and expectorant effects.Conclusion Based on the above research,farcalinol,farcalindiol,and rubimaillin can be used as Q-markers for the antitussive and expectorant effects of Saorilao Qingfei Zhike Capsules.This paper provides reference for the quality standard of Saorilao Qingfei Zhike Capsules.

Acute myocardial infarction(AMI)is a serious disease that endangers human life and health,timely opening of the infarct vessel is the main means of successful treatment.Emergency percutaneous coronary intervention(PCI)is the most effective treatment at present,which can quickly restore myocardial blood supply and save patients'lives.With the maturity of PCI treatment,the survival rate of patients with AMI has improved significantly.However,in recent years,emergency PCI operators have encountered a significant challenge:rare and fatal complications associated with coronary artery injury during emergency PCI are not promptly recognized and treated,leading to an increase in perioperative mortality.At present,there is no unified plan for the management of critical complications during PCI at home and abroad.Therefore,this paper mainly reviews the management measures of complications related to coronary artery injury during surgery,such as coronary artery perforation,non-reflow,coronary artery dissection,and stent thrombosis,and summarizes the progress of relevant treatment measures at home and abroad to help surgeons deal with emergencies timely and correctly and save more patient lives.

Objective:To comprehensively understand the disease burden of liver cirrhosis and other chronic liver diseases caused by alcohol use in China from 1990 to 2019, as well as to predict the trends in disease burden from 2020 to 2030.Methods:The analysis utilized data from the Global Burden of Disease study in 2019 (GBD2019). Key indicators such as incidence rate, mortality rate, disability-adjusted life years (DALY), years of life lost due to premature mortality, and years lived with disability were selected to describe the disease burden of alcohol-related liver cirrhosis and other chronic liver diseases in China from 1990 to 2019. The estimated annual percentage change (EAPC) was used to depict the temporal trends in disease burden. Furthermore, a Bayesian age-period-cohort (BAPC) model was constructed using R software to predict the age-standardized incidence rate (ASIR) and age-standardized mortality rate (ASMR) of alcohol-related liver cirrhosis and other chronic liver diseases in China from 2020 to 2030.Results:From 1990 to 2019, the incidence of alcohol-related liver cirrhosis and other chronic liver diseases in China showed an upward trend, with an EAPC of 0.31% (95% CI: 0.10%-0.52%). However, the DALY declined, with an EAPC of -2.81% (95% CI: -2.92% - -2.70%). The ASMR showed a downward trend, with an EAPC of -2.55% (95% CI: -2.66% - -2.45%). The highest incidence of cirrhosis of liver caused by alcohol and other chronic liver diseases was reported in the age group of 35-49 years, while the ASMR increased gradually with age, with a significant rise after the age of 30. The age-standardized DALY rate peaked between the ages of 55 and 64. The disease burden indicators for males were consistently higher than those for females during the same period. According to the predictions of the BAPC model, from 2020 to 2030, the ASIR for cirrhosis of liver caused by alcohol and other chronic liver diseases in the entire population of China was projected to increase from 3.45/100 000 in 2020 to 3.78/100 000 in 2030, a growth of 9.57%. Conversely, the ASMR was expected to decrease from 1.45/100 000 in 2020 to 1.24/100 000 in 2030, a reduction of 14.48%. Conclusions:The disease burden of cirrhosis of liver caused by alcohol and other chronic liver diseases remained serious in China, especially in men and the middle-aged to elderly population. There is a pressing need to prioritize attention and resources towards these groups. Despite the projected decrease in ASMR, the ASIR continued to rise and is expected to persist in its upward trend until 2030.

Objective:To investigate the self-healing of congenital auricular deformity (CAD) and the efficacy of the auricle corrector in infants.Methods:The infants with CAD who were born in the Affiliated Maternity and Child Health Care Hospital of Nantong University from January to December 2020 were collected. The patients who disagreed with the use of auricle corrector were included in the observation group. The patients were followed up on the day of one month and one year after birth by phone or WeChat, and the self-healing rate (the proportion of the number of ears found to be healed in the total number of affected ears after follow-up) of auricle was calculated. The patients treated with auricle corrector were included in the non-invasive correction group, which was treated with domestic auricle corrector. And according to the initial correction age, the patients were divided into ≤7 d, 8-28 d and >28 d three subgroups. The patients were followed up on the day of one month and one year after treatment by phone or WeChat, and the effective rate(the proportion of healed ears to the total number of affected ears after treatment) was calculated. And statistical analysis was used in the three subgroups of initial correction age ≤7 d, 8-28 d, >28 d. Variance analysis was used for general comparison between three groups, and LSD- t test for the comparison between two groups. P<0.05 was considered statistically significant. Results:A total of 43 children (71 ears, 34 left ears and 37 right ears) were included in the observation group, including 21 males and 22 females, (2.1±0.3) days after birth. In the non-invasive correction group, 24 children (41 ears, 20 left ears and 21 right ears) were included, including 8 males and 16 females, (29.1±23.8) days after birth. There were 6 cases (10 ears) in the initial correction age group ≤7 days, 6 cases (9 ears) in the 8-28 days group, and 12 cases (22 ears) in the >28 days group. In the observation group (71 ears), the rates of self-healing on the day of one month and one year after birth were 29/71 and 30/71, respectively, including 23/31 and 24/31 for lop ear, 3/6 for Stahl’s ear, 3/3 for complex deformity, and 0 for other ear deformities. The effective rates were 41/41 and 35/41 one month and one year after treatment in the 24 children (41 ears) in the non-invasive correction group, respectively. Among them, the helical rim deformity was 12/12, lop ear 3/3, cup ear 7/7 and 5/7, Stahl’s ear 4/4, contracted ear 6/6, 5/6, prominent ear 2/2 and 0, the complex deformity 6/6 and 5/6, and microtia(Ⅰ) 1/1. The auricular deformities reoccurred in a total of 4 children (6 ears) 1 year after the end of treatment. According to the initial correction age into three groups, the treatment duration of the auricle corrector was (31.8±11.2) days, (31.3±10.1) days and (41.8±13.8) days, and the difference among the three groups was statistically significant ( F=3.42, P=0.043). There was no statistical significance between the groups ≤7 days and 8-28 days ( P=0.936), but there was statistical significance in the treatment duration between the groups ≤7 days and >28 days ( P=0.043), and between the groups 8-28 days and > 28 days ( P=0.041). Conclusion:CAD can self-heal to some extent. Self-healing rate is higher in lop ear and Stahl’s ears. The domestic auricle corrector has a good effect on CAD. The older the age of initial correction is, the longer the time of correction is. The type of CAD has a certain influence on the correction effect.

Objective : To study the correlation between cerebral white matter structure with cognitive function and blood biochemical indexes in patients with end stage renal disease (ESRD) . Methods : The diffusion tensor imaging (DTI) data of 64 ESRD patients and 47 age and sex matched healthy people were collected. Tract⁃based spatial statistics (TBSS) and XTRACT analysis methods were used to compare the differences in diffusion parameters between the two groups. Pearson correlation analysis was used to detect the correlation between various diffusion parameters and blood biochemical indexes and cognitive related scales. Results : The values of FA in the ESRD group generally decreased (P < 0. 05) . The values of MD, AD and RD obviously increased (P < 0. 05) . The scores of mini mental state examination (MMSE) and Montreal cognitive assessment (MoCA) decreased (P < 0. 01), while that of trail making test A part (TMT⁃A) increased (P < 0. 05) . In the ESRD group, the values of FA in the right anterior thalamic radiation, optic radiation, acoustic radiation, and cingulum were negatively correlated with the levels of creatinine and urea nitrogen, and positively correlated with MoCA′s scores, and the values of MD and RD of these tracts were positively correlated with the concentration of urea. The values of FA in optic radiation, acoustic radiation and left temporal of cingulum were negatively correlated with the scores of TMT⁃A. The values of FA in the vertical occipital fasciculus, inferior fronto⁃occipital fasciculus, left middle longitudinal fasciculus and forceps major were negatively correlated with the concentration of creatinine. The values of FA in the left arcuate fasciculus were positively correlated with the MoCA′s score, the values of MD and RD of these tracts were positively correlated with the concentration of creatinine, and negatively correlated with the scores of MMSE and MoCA. The values of FA in the right superior longitudinal fasciculus, the right corticospinal tract and the right frontal aslant tract werepositively correlated with the MoCA′s score, the values of MD and RD of these tracts were positively correlated with the concentration of urea; the values of MD and RD in the left fornix were positively correlated with the level of creatinine and urea. Conclusion The structural integrity of white matter in ESRD patients is extensively damaged, which is significantly associated with a variety of cognitive impairments. Serum creatinine and urea nitrogen may be risk factors for the changes in white matter.

Helicobacter pylori (H. pylori), creating a global infection rate over 50%, presents great challenges in clinical therapies due to its complex pathological microenvironment in vivo. To improve the eradication efficacy, herein we fabricated a pharmaceutical vesicle RHL/Cl-Ch-cal where cholesterol-PEG, calcitriol and first-line antibiotic clarithromycin were co-loaded in the rhamnolipid-composed outer lipid layer. RHL/Cl-Ch-cal could quickly penetrate through gastric mucus layer to reach H. pylori infection sites, and then effectively destroyed the architecture of H. pylori biofilms, killed dispersed H. pylori and inhibited the re-adhesion of residual bacteria (called biofilms eradication tetralogy). Moreover, RHL/Cl-Ch-cal activated the host immune response to H. pylori by replenishing cholesterol to repair lipid raft on the cell membrane of host epithelial cells. Finally, RHL/Cl-Ch-cal killed the intracellular H. pylori through recovering the lysosomal acidification and assisting degradation. In experiments, RHL/Cl-Ch-cal demonstrated prominent anti-H. pylori efficacy in the classical H. pylori-infected mice model. Therefore, the study provides a "comprehensive attack" strategy for anti-H. pylori therapies including biofilms eradication tetralogy, immune activation and intracellular bacteria killing.
