Using a novel(OH)n-C60@SiO2@Tm2O3@Ca5(PO4)3(OH)quaternary nano-particles/cross-linked chitosan coated open-tubular capillary column(QNPsC-OTCC)as the analytical column,a new method for highly selective determination of taurine(TAU)in functional drinks using pre-column derivatization capillary electrochromatography coupled with electrochemiluminescence(CEC-ECL)detection was established.In the experiments,it was found that adding hexamethylenetetramine as a co-catalyst in N-methylation derivative reaction could quantitatively convert TAU into a single derivative product that cuold be detected by ECL.With the help of Ru(bpy)32+reagent,the ECL peak intensity of TAU derivative was increased by more than 1000 times compared to the original TAU.In addition,a Ru-containing d-f cyano-bridged heterometallic coordination polymer modified platinum electrode was used instead of a bare platinum electrode as working electrode for ECL detection,which resulted in a further increase of the peak response of TAU derivatives about 5.7 times.Under optimized analytical conditions,by using betastatin hydrochloride(BSH)as the internal standard and simultaneously derivatized with TAU,the relative ratio of peak intensity of TAU and BSH derivatives showed a linear relationship with the initial TAU concentration in a two-segment ranges of 0.2-6.0 mmol/L and 6.0-10 mmol/L.The limit of detection of TAU was 0.09 mmol/L(S/N=3).The developed method was applied to determination of TAU contents in four commercial functional drink samples,and the relative standard deviations(RSDs)for relative intensity ratio were less than 0.9％,and the recoveries were in the range of 95.0％～102.0％,indicating good practicability of the method.

Objective To evaluate the predictive significance of contrast-enhanced ultrasound parameters in combination with serum levels of chemokine ligand 9(CXCL9)and insulin-like growth factor-binding protein 3(IGFBP-3)for the recurrence of hepatocellular carcinoma following interventional therapy.Methods A total of 212 patients with liver cancer who received interventional therapy at the hospital between June 2022 and Novem-ber 2023 were selected and categorized into Group A(61 cases)and Group B(151 cases)based on whether tumor recurrence occurred within one year following the intervention.Multivariate logistic regression analysis was con-ducted to identify potential influencing factors associated with post-treatment recurrence.The predictive perfor-mance of contrast-enhanced ultrasound parameters combined with serum biomarkers was evaluated using receiver operating characteristic(ROC)curve analysis.Results The levels of several factors including a tumor with a maximum diameter exceeding 3 cm,presence of microvascular invasion,high peak intensity(PI),short time to peak(TTP),short arrival time(AT),elevated serum CXCL9,and decreased serum IGFBP-3 were identified as indepen-dent risk factors for recurrence in patients with hepatocellular carcinoma following interventional therapy(P<0.05).The area under the curve(AUC)for the combination of PI,TTP,AT,along with serum levels of CXCL9 and IGFBP-3,in predicting recurrence after interventional therapy was significantly higher than that of individual fac-tors alone(P<0.05).Conclusions The risk of recurrence in patients undergoing interventional therapy for liver cancer is substantial,and it is influenced by a range of independent risk factors.Combining contrast-enhanced ul-trasound parameters with serum levels of CXCL9 and IGFBP-3 may enhance the predictive accuracy for tumor re-currence in these patients.

Traditional Chinese medicine (TCM) is a well-accepted therapy for atopic dermatitis (AD). However, there are currently no evidence-based guidelines integrating TCM and Western medicine for the treatment of AD, limiting the clinical application of such combined approaches. Therefore, the China Association of Chinese Medicine initiated the development of the current guideline, focusing on key issues related to the use of TCM in the treatment of AD. This guideline was developed in accordance with the principles of the guideline formulation manual published by the World Health Organization. A comprehensive review of the literature on the combined use of TCM and Western medicine to treat AD was conducted. The findings were extensively discussed by experts in dermatology and pharmacy with expertise in both TCM and Western medicine. This guideline comprises 23 recommendations across seven major areas, including TCM syndrome differentiation and classification of AD, principles and application scenarios of TCM combined with Western medicine for treating AD, outcome indicators for evaluating clinical efficacy of AD treatment, integration of TCM pattern classification and Western medicine across disease stages, daily management of AD, the use of internal TCM therapies and proprietary Chinese medicines, and TCM external treatments.

OBJECTIVE: Coronavirus disease 2019 (COVID-19) can result in fatigue and post-exertional malaise; however, whether severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection exacerbates lower urinary tract symptoms (LUTS) is unclear. This study investigated the association between prenatal SARS-CoV-2 infection and postpartum LUTS. METHODS: A multicenter, retrospective cohort study was conducted at two tertiary hospitals in China from November 1, 2022, to November 1, 2023. Participants were classified into infected and uninfected groups based on SARS-CoV-2 antigen results. LUTS prevalence and severity were assessed using self-reported symptoms and the Incontinence Impact Questionnaire-Short Form (IIQ-7). Pelvic floor muscle activity was measured using electromyography following the Glazer protocol. Group comparisons were performed to evaluate the association of SARS-CoV-2 infection with LUTS and electromyography parameters, with stratified analyses conducted using SPSS version 26.0. RESULTS: Among 3,652 participants (681 infected, 2,971 uninfected), no significant differences in LUTS prevalence or IIQ-7 scores were observed. However, SARS-CoV-2 infection was an independent factor influencing the electromyographic activity of the pelvic floor muscles (mean tonic contraction amplitudes), regardless of delivery mode ( P = 0.001). CONCLUSION Prenatal SARS-CoV-2 infection was not significantly associated with an increased risk of postpartum LUTS but independently altered pelvic floor muscle electromyographic activity, suggesting potential neuromuscular effects.

Objective To assess the clinical and safety outcomes of endovascular therapy(EVT)administered beyond 24 h after the onset of symptoms in patients with acute ischemic stroke(AIS)resulting from middle cerebral artery atherosclerotic occlusion.Methods We enrolled consecutive AIS patients with middle cerebral artery atherosclerotic occlusion who received EVT in our hospital between January 2020 and June 2023 and divided them into two groups based on the time from AIS onset to EVT:EVT≤24 h group and EVT＞24 h group.The National Institutes of Health Stroke Scale(NIHSS)scores after surgery,90-day functional independence(defined as mRS 0-2),symptomatic ICH(sICH),postoperative acute thrombosis,as well as mortality,were analyzed in the two groups of patients.Results A total of 161 patients were recruited,with 106 cases in the EVT≤24 h group and 55 cases in the EVT＞24 h group.The NIHSS scores declined after EVT in both groups(P＜0.01).The NIHSS scores after surgery were lower in the EVT≤24 h group(median:4.5 vs.7.0,P＜0.05).90-day functional independence(45.3％vs.30.9％,95％CI:0.93-3.68),sICH(5.7％vs.9.1％,95％CI:0.18-2.06),postoperative acute thrombosis(6.6％vs.3.6％,95％CI:0.37-9.34),and mortality(3.8％vs.1.8％,95％CI:0.23-19.42)did not differ significantly between the groups(P＞0.05).Conclusion Our findings support EVT feasibility in selected patients with middle cerebral artery atherosclerotic occlusion beyond 24 h.Prospective studies are warranted for confirmation.

Objective:To explore the association between oral health status, the lower respiratory tract microbiome, and the frequent acute exacerbation phenotype in chronic obstructive pulmonary disease (COPD).Methods:This cross-sectional study enrolled 39 patients with acute exacerbation of chronic obstructive pulmonary disease (AECOPD) hospitalized in the Department of Respiratory Medicine, Henan Provincial People′s Hospital between March 2021 and December 2022. Based on the number of hospitalization episodes for acute exacerbation in the past year, patients were divided into a frequent exacerbator group (≥2 times, n=28) and a non-frequent exacerbator group (<2 times, n=11). Bronchoalveolar lavage fluid (BALF) samples were collected from all subjects for metagenomic next-generation sequencing (mNGS). Oral health indicators and clinical data were also collected. Statistical analyses were performed using Spearman correlation analysis and multivariable Firth logistic regression analysis. Results:The frequent exacerbation group showed a significantly higher percentage of individuals with≥8 tooth loss compared to the non-frequent exacerbation group (96.4% vs 18.2%, P<0.001), a significantly younger age at first tooth loss in adulthood (53.96±7.30 years vs 62.10±5.80 years, P=0.003), and a significantly higher proportion of individuals who hardly brushed their teeth (50.00% vs 9.09%, P=0.038). The alpha-diversity indices of the lower respiratory tract microbiota were significantly lower in the frequent exacerbation group than in the non-frequent exacerbation group (all P<0.01). The relative abundances of Bacillota, Bacteroidota, Fusobacteriota, Streptococcus, Prevotella, Veillonella, Neisseria, Rothia, Prevotellamelaninogenica, Prevotellajejuni, Rothia mucilaginosa, Veillonella parvula, and Neisseria subflava were lower in the frequent exacerbation group (all P<0.05). In patients with AECOPD, the exacerbation frequency and the presence of ≥8 tooth loss were both negatively correlated with the Shannon index ( r=-0.854, P<0.001; r=-0.642, P<0.001, respectively). Further analysis revealed that Bacillota ( r=-0.862, P<0.001) and Streptococcus ( r=-0.814, P<0.001) were significantly negatively correlated with exacerbation frequency, while Pseudomonas was positively correlated with exacerbation frequency (all P<0.05). Bacillota ( r=0.369, P=0.021), Fusobacteriota ( r=0.368, P=0.021), and Veillonella ( r=0.379, P=0.017) were positively correlated with FEV 1% predicted. Multivariable Firth logistic regression analysis revealed that the first principal component of the microbial community ( OR=2.29, 95% CI: 1.20-11.07) and the loss of≥8 teeth ( OR=14.37, 95% CI: 1.42-482.51) were independent factors associated with frequent acute exacerbations. Conclusion:Frequent acute exacerbations of COPD are significant association with deteriorated oral health and dysbiosis of the lower respiratory tract microbiome, characterized by reduced alpha-diversity and depletion of commensal bacteria.

Body weight abnormalities, including overweight, obesity, and underweight, have become a dual public health challenge in Chinese adults: overweight and obesity lead to a variety of chronic complications, while underweight increases the risks of malnutrition, sarcopenia, and organ dysfunction. To systematically address these issues, multidisciplinary experts in endocrinology, sports science, nutrition, and psychiatry from various regions have held multiple weight management seminars. Based on the latest epidemiological data and clinical evidence, they expanded the guideline to include assessment and intervention strategies for underweight, in addition to the core content of obesity management. This guideline outlines the etiological mechanisms, evaluation methods, and multidimensional management strategies for overweight and obesity, covering key areas such as diagnosis and assessment, medical nutrition therapy, exercise prescription, pharmacological intervention, and psychological support. It is intended to provide a scientific and standardized approach to weight management across the adult population, aiming to curb the rising prevalence of obesity, mitigate complications associated with abnormal body weight, and improve nutritional status and overall quality of life.

Objective To explore the feasibility and corresponding implementation methods of constructing a sample resource bank based on individual-level data of completed clinical trials and using it to construct external controls for drug/device clinical trials.Methods Taking the pre-marketing clinical trial of transcatheter active valve replacement(TAVR)for the treatment of aortic valve stenosis as an example,the individual-level databases of multiple trials were standardized to form a sample bank.The original data of any trial in the sample bank were selected as the experimental group,and the remaining samples were selected as the control group.The potential confounding was handled by using the propensity score matching and stratification methods to clarify the process of constructing external controls based on the sample bank of individual-level data of clinical trials.Results This study included individual-level data of single-group trials of 4 TAVR devices,with a total of 569 subjects(59.2%male).The number of subjects in Trials 1 to 4 was 120,120,163,and 166,respectively.Propensity score matching enabled the matching of 113,117,125,and 147 subjects with comparable or similar characteristics from individual-level data from other trials,respectively,demonstrating a high matching success rate.The PS score distribution plot after stratification showed that the proportions of subjects in the experimental and control groups in strata 1 to 5 in scheme 1 were 4/103,11/103,22/92,32/87,and 51/64,respectively.For all constructed external controlled trials,a certain number of control samples with similar baseline characteristics to the experimental groups were distributed within each propensity score stratum.The results of the simulation test also reflected the potential differences between different devices in the 12-month all-cause mortality rate.Conclusions The sample bank constructed with individual-level data from clinical trials,as a high-quality data source,can serve as a source of external control for single-arm trials in the same field,and as a useful supplement to the external control scenario of real-world evidence to support drug and device development.At the same time,targeted research on research methods and bias control measures in related fields is also needed.
