Acute kidney injury (AKI) is a critical clinical condition characterized by rapid renal function decline, with high morbidity, mortality, and healthcare costs. Traditional Chinese medicine (TCM) has shown potential effects on mitigating oxidative stress and programmed cell death in AKI models. Scutellaria barbata D. Don (SB) and Scleromitrion diffusum (Willd.) R. J. Wang (SD), a classic TCM herbal pair exhibited anti-inflammatory and antioxidant activities. Using advanced chromatographic separation technology, we enriched the effective fractions of water extracts from SB-SD, obtaining self-assembled herbal nanoparticles (SB and SD nanoparticles, SSNPs) rich in flavonoids and terpenoids. These SSNPs demonstrated robust antioxidant properties in vitro and mitigated AKI progression in vivo by activating the nuclear factor erythroid 2-related factor 2 (Nrf2) signaling pathway. Oral administration of SSNPs in mice resulted in absorption into the bloodstream, formation of a protein corona, reduced macrophage phagocytosis, and enhanced bioavailability and renal targeting. Furthermore, we investigated the self-assembly principle of SSNPs using representative flavonoids and terpenoids. Kinetic studies and in situ transmission electron microscopy (in situ TEM) revealed that these compounds self-assemble via supramolecular forces like hydrogen bonding and π-π interactions, forming stable nanostructures. This study elucidates the renoprotective effects and mechanisms of SB and SD, and provides a novel approach for the development of TCM-based nanomedicines, highlighting the potential of nano-TCM in AKI treatment.

BACKGROUND:The study of the lumbar spine and pelvis in patients with Lenke type 5 lordosis is limited to the coronal and sagittal planes,and the three-dimensional relationship between the scoliosis and the pelvis has not yet been clarified. OBJECTIVE:To analyze the effect of lumbar scoliosis on the pelvis in patients with Lenke type 5 lordosis and to study the correlation between the lumbar spine and the three-dimensional spatial position of the pelvis. METHODS:Imaging data of 60 patients with Lenke type 5 lordosis scoliosis admitted to the 3D Printing Reception Center of Shanghai Ninth People's Hospital,Shanghai Jiao Tong University School of Medicine from January 2019 to September 2023 were retrospectively analyzed,including Cobb angle,coronal pelvic tilt,lumbar lordosis,left and right pelvic hip width ratio(sacroiliac-anterior superior iliac spine),spinal rotation angle,pelvic tilt,sacral slope,pelvic incidence,coronal deformity angular ratio,sagittal deformity angular ratio,C7 plumb line-center sacral vertical line,apical vertebral translation,and coronal sacral inclination.The information was summarized as a database.SPSS 22.0 software was used to analyze the data related to the lumbar spine and pelvis of the patients with Lenke type 5 primary lumbar curvature adolescent idiopathic scoliosis using Spearman's correlation analysis and linear regression. RESULTS AND CONCLUSION:(1)Cobb angle was highly positively correlated with coronal deformity angular ratio,apical vertebral translation,and spinal rotation angle(r=0.91,r=0.841,r=0.736).(2)Coronal deformity angular ratio was highly positively correlated with apical vertebral translation(r=0.737),moderately positively correlated with C7 plumb line-center sacral vertical line(r=0.514),and moderately negatively correlated with sagittal deformity angular ratio(r=-0.595).(3)There was a high positive correlation between lumbar lordosis and sagittal deformity angular ratio(r=0.942)and a moderate negative correlation with coronal deformity angular ratio(r=-0.554).(4)There was a moderate positive correlation between Cobb angle with coronal pelvic tilt and coronal sacral inclination(r=0.522,r=0.534)and a moderate positive correlation between C7 plumb line-center sacral vertical line and coronal pelvic tilt(r=0.507).Apical vertebral translation with coronal pelvic tilt and coronal sacral inclination showed a moderate positive correlation(r=0.507,r=0.506).Lumbar lordosis with sacral slope and pelvic incidence showed a moderate positive correlation(r=0.512,r=0.538).Sagittal deformity angular ratio was moderately positively correlated with sacral slope and pelvic incidence(r=0.614,r=0.621).(5)Studies have found that the relative position of the lumbar spine and the pelvis is closely related in the horizontal,sagittal and coronal planes.When the lumbar spine affects scoliosis and is rotated,the relative position of the pelvis will also change to compensate,which indicates that while correcting scoliosis,the correction of the pelvis cannot be ignored.

ObjectiveTo explore the current status and issues regarding the application of ancient books in clinical practice guidelines and expert consensus of traditional Chinese medicine （TCM） published in China， and to provide methodological recommendations for the incorporation of ancient books in the development of TCM guidelines. MethodsWe searched China National Knowledge Infrastructure （CNKI）， WanFang Data， VIP， SinoMed， PubMed， Embase， as well as six industry websites including China Association of Chinese Medicine， National Group Standards Information Platform， and Chinese Association of the Integration of Traditional and Western Medicine，etc. TCM clinical practice guidelines or expert consensus issued during January 1st， 2017， to November 26th， 2022 were searched. Clinical practice guidelines or expert consensus that explicitly referred to ancient books were included， and the content regarding the searching for ancient books， sources of access to ancient books， methods of evaluating the level of evidence， methods of evaluating the level of recommendation， and methods of evaluating the evidence for the ancient books were analysed. ResultsA total of 1,215 TCM clinical practice guidelines or expert consensus were retrieved， with 442 articles explicitly mentioning the application of ancient books， including 300 （67.87%） clinical practice guidelines and 142 （32.13%） expert consensus. Sixty of the 442 publications explicitly reported that ancient books searching had been conducted （13.57%）； among these 60 publications 27 （45.00%） explicitly reported ancient books searching strategies， and the most frequent method was manual searching with a total of 24 articles （40.00%）. The most popular search source was Chinese Medical Dictionary， a TCM classics database， with a total of 18 articles. 197 articles （44.57%） explicitly reported the evaluation criteria for the level of evidence， of which 141 articles （71.57%） involved the evaluation criteria for the ancient books； 413 articles （93.44%） mentioned ancient books in the recommendations， and only the source of formula name was mentioned in 409 （99.03%） of the publications. ConclusionThe current application of ancient books in TCM clinical practice guidelines and expert consensus is limited， with issues of non-standard searching and evaluation methods. Standar-dization and uniformity are needed in evidence grading and recommendation standards. Future research should clarify the scope and methods of applying ancient book， emphasize their integration with modern research evidence， and enhance their value and quality in the development of TCM clinical practice guidelines.

ObjectiveTo explore the role of saikosaponin D （SSD） targeting signal transducer and activator of transcription 3 （STAT3） in inducing apoptosis of bladder cancer cells by computer-aided drug design and experimental verification. MethodThe druggability and biotoxicity of SSD were explored by Bayesian classifier modeling. The information about SSD， the active ingredient of Bupleuri Radix， was searched against the Traditional Chinese Medicine Systematic Pharmacology Database and Analysis Platform （TCMSP）. The targets of SSD were predicted by PubChem， TCMSP， a Bioinformatics Analysis Tool for Molecular mechANism of Traditional Chinese Medicine （BATMAN-TCM）， Coremine， an Encyclopedia of Traditional Chinese Medicine （ETCM）， and SwissTargetPrediction. GeneCards， Therapeutic Target Database （TTD）， and Online Mendelian Inheritance in Man （OMIM） were employed to predict the potential therapeutic targets of bladder cancer. Then， the common targets shared by SSD and bladder cancer were selected for Gene Ontology （GO） and Kyoto Encyclopedia of Genes and Genomes （KEGG） pathway enrichment analyses. Molecular docking was adopted to explore the binding affinity and structural stability of SSD with target proteins. Cytoscape 3.9.1 was used to construct the STAT3-drug regulatory network and STAT3-apoptosis regulatory network. UM-UC-3 cells were treated with 0， 5， 10， 15 μmol·L^-1 SSD for 24 h. Then， flow cytometry was used to detect the apoptosis of bladder cancer cells， and Western blot was employed to determine the protein levels of B-cell lymphoma-2 （Bcl-2）， Bcl-2-associated X protein （Bax）， Bcl-2-associated death promoter （Bad）， STAT3， and phosphorylation （p）-STAT3. ResultBayesian classifier modeling and molecular docking showed that SSD had low biotoxicity and bound well to the target protein STAT3 to form a stable protein-ligand complex. There were 282 common targets between bladder cancer and SSD， among which STAT3 was the most central target. The GO enrichment analysis showed that the potential core therapeutic targets involved 3 036 biological processes， 82 cellular components， and 171 molecular functions. The KEGG enrichment analysis showed that the potential core targets were mainly related to the C-type lectin receptor signaling pathway， Toll-like receptor signaling pathway， and cell apoptosis pathway. The STAT3-drug regulatory network and STAT3-apoptosis regulatory network showed that 29 drugs interacted with STAT3， and 27 apoptosis-related genes had a strong correlation with STAT3. Flow cytometry showed that the apoptosis rate increased with the increase in SSD concentration （P<0.05）. Western blotting results showed that SSD down-regulated the protein levels of p-STAT3 and Bcl-2 and up-regulated the protein levels of Bax and Bad in a concentration-dependent manner （P<0.05）. ConclusionSSD has good druggability and low biotoxicity. It may promote the apoptosis of bladder cancer cells by targeting STAT3.

Cohort study is one of the important research methods in analytical epidemiology because of its clear time sequence relationship, which is better than other observational studies in demonstrating causal association. However, screening diagnosis or other methods are often used to exclude the individuals with outcome events during the enrollment process of the subjects in cohort studies. The accuracy of screening diagnosis and the effectiveness of exclusion will affect the accuracy of the baseline status assessment of the subjects included in the study, which may lead to the causal time sequence reversal of exposure-outcome in the estimation of causal effect. Landmark analysis can be used to control reverse causality by excluding subjects with potentially unknown expose-outcome timing. In this paper, we describe the basic principles and analytical steps of landmark analysis, and use data from the Chinese Longitudinal Healthy Longevity Survey to explore the relationship between physical activity and frailty, and introduce the specific application of landmark analysis for the purpose of facilitating its application and inferring causal effects more accurately in cohort studies.

With completing a baseline survey of a large natural population cohort, conducting regular follow-up has become a key factor in further improving the quality of cohort construction and ensuring its sustainable development. Typical cohort follow-up methods include repeat surveys, routine monitoring, and community-oriented surveillance. However, in practical applications, there are often issues such as high costs, difficulty, and high error rates. Telephone follow-up is an important supplementary method to the methods mentioned above, as it has the characteristics of low cost, fast response, and high quality. However, the with difficult organization, quality control is challenging, response rates are low, and management levels vary widely, which limits its widespread use in large-scale population cohort studies. Given the above problems, this study draws on customer relationship management based on the actual needs of the China Northwest Cohort follow-up. It relies on the REDCap electronic data collection platform to build a telephone follow-up management and quality control system. Targeted solutions are provided for key issues in telephone follow-up implementation, including organizational structure, project management, data collection, and process quality control, to improve the quality control level of telephone follow-up comprehensively and thereby enhance the quality and efficiency of follow-up. We hope to provide standardized follow-up programs and efficient quality control tools for newly established and existing cohort studies.

With the development of modern sequencing techniques and bioinformatics, genomes that were once thought to be noncoding have been found to encode abundant functional micropeptides (miPs), a kind of small polypeptides. Although miPs are difficult to analyze and identify, a number of studies have begun to focus on them. More and more miPs have been revealed as essential for energy metabolism homeostasis, immune regulation, and tumor growth and development. Many reports have shown that miPs are especially essential for regulating glucose and lipid metabolism and regulating mitochondrial function. MiPs are also involved in the progression of related diseases. This paper reviews the sources and identification of miPs, as well as the functional significance of miPs for metabolism-related diseases, with the aim of revealing their potential clinical applications.

The printing technologies and materials often chosen for 3D printed orthotic insoles are mainly FDM and EVA. 3D printed orthotic insoles is effective on plantar pressure, comfort and foot movement function of flatfoot.

Objective:To explore anti-seizure medication (ASM) treatment patterns, seizures, maternal and fetal outcomes and offspring outcomes of pregnant women with epilepsy (PWWE) who withdraw ASM in the first trimester of pregnancy.Methods:A retrospective analysis was performed on the PWWE database registered in West China Hospital, Sichuan University from January 2009 to October 2022. Patients who withdrew ASM therapy in the first trimester and those who maintained ASM therapy throughout pregnancy were included. Withdrawal in the first trimester was defined as discontinuation of ASM between 0 and 3 months of pregnancy. Sixty-five PWWE (withdrawal group) who withdraw ASM in the first trimester were included, and 130 PWWE (maintained-therapy group) who took ASM throughout pregnancy in West China Hospital during the same period were matched 1∶2. Demographic characteristics, ASM, seizures, maternal and fetal outcomes within 1 year were compared between the 2 groups. In the subgroup analysis, the withdrawal group was divided into a full withdrawal group ( n=53) and a resumption group ( n=12) according to whether the ASM was resumed in the second and third trimesters of pregnancy, and the 2 groups were stratified and compared. Results:In the withdrawal group, the proportion of patients with bachelor degree below [72.3% (47/65) vs 54.6% (71/130), χ 2=5.68, P=0.017], family income less than 5 000 yuan per capita [44.6% (29/65) vs 18.5% (24/130), χ 2=14.98, P<0.001], a family history of epilepsy [12.3% (8/65) vs 3.1% (4/130), χ 2=4.90, P=0.027], and a second pregnancy [43.1% (28/65) vs 26.2% (34/130), χ 2=5.72, P=0.017] was higher than in the maintained-therapy group. The proportion of patients who received multiple ASM was lower in the withdrawal group than in the maintained-therapy group [16.9% (11/65) vs 38.5% (50/130), χ 2=9.35, P=0.002]. In the withdrawal group, the rate of seizures with tonic-clonic seizures during pregnancy [50.8% (33/65) vs 31.5% (41/130), χ 2=6.81, P=0.009] and seizure exacerbation during pregnancy [32.3% (21/65) vs 9.2% (12/130), χ 2=16.41, P<0.001] was higher. The preterm birth rate in the withdrawal group was lower than that in the maintained-therapy group [4.6% (3/65) vs 19.2% (25/130), χ 2=101.70, P<0.001]. The rate of seizure exacerbation during pregnancy was higher in the resumption group than in the full withdrawal group [7/12 vs 26.4% (14/53), χ 2=3.22, P=0.073]. Conclusions:PWWE with a family history of epilepsy and a second pregnancy were more likely to withdraw ASM during pregnancy. After withdrawal, the seizures during pregnancy were significantly worse, but the preterm birth rate of offspring was relatively reduced.
