Medical institutions, with their clinical practice foundation and abundant human use experience data, have become important carriers for the inheritance and innovation of traditional Chinese medicine(TCM) and the "cradles" of the preparation of new TCM. To effectively promote the transformation of new TCM originating from the TCM clinical practice in medical institutions and establish an effective evaluation index system for the transformation of new TCM conforming to the characteristics of TCM, consensus experts adopted the literature research, questionnaire survey, Delphi method, etc. By focusing on the policy and technical evaluation of new TCM originating from the TCM clinical practice in medical institutions, a comprehensive evaluation from the dimensions of drug safety, efficacy, feasibility, and characteristic advantages was conducted, thus forming a comprehensive evaluation system with four primary indicators and 37 secondary indicators. The expert consensus reached aims to encourage medical institutions at all levels to continuously improve the high-quality research and development and transformation of new TCM originating from the TCM clinical practice in medical institutions and targeted at clinical needs, so as to provide a decision-making basis for the preparation, selection, cultivation, and transformation of new TCM for medical institutions, improve the development efficiency of new TCM, and precisely respond to the public medication needs.

To explore the variation laws of volatile oil during the extraction process of Artemisiae Argyi Folium and its impact on the quality of the medicinal solution, as well as to achieve precise control of the extraction process, this study employed headspace solid phase microextraction gas chromatography-mass spectrometry(HS-SPME-GC-MS) in combination with multiple light scattering techniques to conduct a comprehensive analysis, identification, and characterization of the changes in volatile components and the physical properties of the medicinal solution during the extraction process. A total of 82 volatile compounds were identified using the HS-SPME-GC-MS technique, including 21 alcohols, 15 alkenes, 14 ketones, 9 acids, 6 aldehydes, 5 phenols, 3 esters, and 9 other types of compounds. At different extraction time points(15, 30, 45, and 60 min), 71, 72, 64, and 44 compounds were identified in the medicinal solution, respectively. It was observed that the content of volatile components gradually decreased with the extension of extraction time. Through multivariate statistical analysis, four compounds with significant differences during different extraction time intervals were identified, namely 1,8-cineole, terpinen-4-ol, 3-octanone, and camphor. RESULTS:: from multiple light scattering techniques indicated that at 15 minutes of extraction, the transmittance of the medicinal solution was the lowest(25%), the particle size was the largest(0.325-0.350 nm), and the stability index(turbiscan stability index, TSI) was the highest(0-2.5). With the extension of extraction time, the light transmittance of the medicinal solution improved, stability was enhanced, and the particle size decreased. These laws of physicochemical property changes provide important basis for the control of Artemisiae Argyi Folium extraction process. In addition, the changes in the bioactivity of Artemisiae Argyi Folium extracts during the extraction process were investigated through mouse writhing tests and antimicrobial assays. The results indicated that the analgesic and antimicrobial effects of the medicinal solution were strongest at the 15-minute extracting point. In summary, the findings of this study demonstrate that the content of volatile oil in Artemisiae Argyi Folium extracts gradually decreases with the extension of extraction time, and the variation in volatile oil content directly influences the physicochemical properties and pharmacological efficacy of the medicinal solution. This discovery provides important scientific reference for the optimization of Artemisiae Argyi Folium extraction processes and the development and application of process analytical technologies.

Abstract In recent years, the prevalence of overweight and obesity among children and adolescents has risen rapidly, posing a serious threat to their physical and mental health. To provide scientific, systematic, and standardized weight management guidance for overweight and obese children and adolescents, the study focuses on the core concept of healthy lifestyle intervention, integrates multidisciplinary expert opinions and research findings,and proposes a comprehensive multidisciplinary intervention framework covering scientific exercise intervention, precise nutrition and diet, optimized sleep management, and standardized psychological support. It calls for the establishment of a multi agent collaborative management mechanism led by the government, implemented by families, fostered by schools, initiated by individuals, optimized by communities, reinforced by healthcare, and coordinated by multiple stakeholders. Emphasizing a child and adolescent centered approach, the consensus advocates for comprehensive, multi level, and personalized guidance strategies to promote the internalization and maintenance of a healthy lifestyle. It serves as a reference and provides recommendations for the effective prevention and control of overweight and obesity, and enhancing the health level of children and adolescents.

Objective To investigate the correlation of corneal α angle and κ angle with lens tilt in normal human eyes using a new swept-source optical biometer.Methods A cross-sectional study was conducted,involving 303 healthy eyes(148 right eyes and 155 left eyes)of patients who visited the First Affiliated Hospital of Kunming Medical University from June to August 2024.ZW-30 swept-source optical biometer was used to collect the lens tilt angle,κ angle(distance from the corneal light reflex to the pupil center),and α angle(distance from corneal light reflex to the corneal geometric center,which is the midpoint of the horizontal white to white(WTW)diameter).The degrees(°)and directions of κ angle and α angle were calculated by the ratio of the above measurements to the anterior chamber depth(ACD)respectively.Spearman correlation analysis and linear regression analysis were employed to evaluate the correlations between the magnitude and direction of corneal α angle,κ angle and lens tilt angle.Results The magnitude and direction of corneal α angle,κ angle,and lens tilt angle in the right eye were as follows respectively:(0.54±0.19)mm(7.81°±3.88°),194.43°±39.75°;(0.27±0.23)mm(4.72°±3.90°),181.07°±79.59°;5.52°±1.67°,188.21°±25.73°.For the left eye,the corresponding values were:(0.47±0.27)mm(8.12°±5.26°),336.04°±46.64°;(0.26±0.27)mm(4.45°±4.80°),322.86°±107.79°;5.50°±1.61°,340.65°±32.84°.Spearman's correlation analysis showed that the correlation coefficients between corneal α angle and lens tilt angle in the right eye were 0.609(distance correlation)and 0.625(angle correlation),while those for κ angle were 0.559(distance correlation)and 0.578(angle correlation).In the left eye,the correlation coefficients between corneal α angle and lens tilt angle were 0.545(distance correlation)and 0.552(angle correlation),and those for κ angle were 0.377(distance correlation)and 0.395(angle correlation).In addition,the correlation coefficient between the direction of corneal α angle and the direction of lens tilt angle in the right eye was 0.343,and that for κ angle direction was 0.284;in the left eye,the correlation coefficients were 0.216(α angle direction)and 0.198(κ angle direction),all with statistical significance(P<0.05).Univariate linear regression analysis showed that lens tilt was positively correlated with both corneal α angle and Kappa angle(P<0.05).Conclusions Corneal α angle and κ angle are highly correlated with lens tilt angle in both eyes,and the correlation of corneal α angle is stronger than that of κ angle in both left and right eyes.The correlation expressed by degree(°)is better than that by distance(mm).It is recommended to refer to the corneal α angle and κ angle expressed in degrees during preoperative evaluation.

Objective To propose a high-precision deep learning-based image assessment method of osteosarcoma chemotherapy efficacy for clinical treatment,as existing methos have low accuracy of osteosarcoma assessment.Methods The low incidence of osteosarcoma led to the small scale of its imaging data and the problem of imbalance in data categories.This study combined deep learning with clinical medical information,combined the bone sarcoma generation module of BoneGAN and the scale lesion information capture module,and proposed OMLA-Net,a deep learning assessment network for chemotherapy effect of bone sarcoma based on multi-scale lesion attention network,which achieved computer-aided bone tumor assessment with integrated data augmentation and focused lesion information through pre-training and generalized loss training.Results In this study,40 cases of osteosarcoma MRI data were used as the basis for the comparison test on the generated dataset,and the OMLA-Net assessment outperformed the SOTA method Conv-LSTM-GAN in terms of the assessment effects such as accuracy and F1 scores,and the difference was statistically significant(Bootstrap statistical method P＜0.05);the subsequent K-fold cross-validation ablation experiments further demonstrated the effectiveness of each module proposed by OMLA-Net.Conclusion OMLA-Net can effectively perform the impact assessment of chemotherapy effect on osteosarcoma,which provides a new idea for subsequent clinical application.

Objective To observe the difference of bone micro-structure in different regions of proximal femur,micro-CT scanning was performed on 30 proximal femur specimens to explain the mechanism of proximal femur fracture and to provide anatomical basis for prosthesis design.Methods Totally 30 intact proximal femur specimens were obtained from 60-80 year-old cadavers.Micro-CT scanning was used to measure the trabecular thickness(Tb.Th),trabecular number(Tb.N),trabecular space(Tb.Sp),connectivity(Conn)and bone mineral density(BMD)and other parameters in 7 regions of proximal femur,including proximal pressure trabecular(PPT),distal pressure trabecular(DPT),femoral head-neck junction(FHNJ),head and neck of femoral neck(HNFN),the base of femoral neck(BPFN),intertrochanteric line(IL)and greater trochanter(GT).Results The bone mineral density of IL and GT were higher than those of BPFN,FHNJ,DPT and PPT.The trabecular thickness of GT was the largest,followed by IL,BPFN and HNFN,and the smallest was FHNJ,DPT and PPT.The trabecular space of IL was larger than that of GT,and the data of both were larger than those of other parts,among which DPT and PPT were the smallest.The trabecular number of IL and GT were the smallest,BPFN,HNFN and FHNJ were larger,and DPT was the largest.The volume fraction of IL was the smallest,BPFN and HNFN were larger,DPT and PPT were the largest.Conclusion The bone density,trabecular thickness,bone volume,and total volume of GT and IL in the proximal femur of elderly patients are all relatively large,so the reason for the high incidence of fractures is not due to weak internal bone microstructure;The bone density,trabecular thickness,and trabecular gap at the proximal and distal ends of the vertical trabecular bone are relatively small.If it is necessary to perform core decompression for prosthesis filling at this location,the design should be conducive to the mechanical conduction of the prosthesis and the regeneration of surrounding bone tissue.

Objective:To explore the effects and mechanisms of Shen-su-yin (SSY) on acute lung injury (ALI) in rats based on untargeted Metabolomics, network pharmacology, and experimental verification.Methods:Untargeted Metabolomics was performed to detect the ingredients of SSY by using ultra-high performance liquid chromatography-Q-exactive orbitrap mass spectrum, and the active ingredients were screened from the detected ingredients. Common targets of the active ingredient targets and ALI targets were utilized to screen hub targets to perform gene ontology (GO) and Kyoto encyclopedia of genes and genomes (KEGG) enrichment analysis. Then, key hub targets were selected from the hub targets, and the active ingredients-hub targets network was built to screen core ingredients. Subsequently, molecular docking was performed between the key hub targets and the core ingredients. 48 rats were randomly and equally divided into 4 groups by using a random number table: normal control group, lipopolysaccharide-induced ALI group, ALI+SSY group, and ALI+dexamethasone group. 24 hours after lipopolysaccharide induction, the levels of respiratory rate, blood lactate, lung wet/dry weight ratio, ALI score, inflammatory factors of bronchoalveolar lavage fluid, and oxidative stress mediators of lung tissue in each group were evaluated, and the expression of phosphatidylinositol 3-kinase (PI3K)-protein kinase B (AKT)-glycogen synthase kinase (GSK) 3β-nuclear factor erythroid 2-related factor 2 (Nrf2)/nuclear factor (NF)-κB signaling pathway was also detected by using Western blot. Finally, one-way analysis of variance, Welch test, or Kruskal-Wallis H test was used to compare data differences among groups. Results:A total of 415 ingredients were detected from the SSY. 66 of the detected ingredients were identified as active ingredients, and 10 of them were selected as core ingredients. The number of common targets, hub targets, and key hub targets was 337, 50, and 10, respectively. Total of 285 biological processes, 32 cellular components, and 51 molecular functions were enriched though GO analysis, and 148 cell signaling pathways such as pathways in cancer and PI3K-AKT signaling pathway were enriched though KEGG analysis. Molecular docking studies revealed that all binding energies between the 10 key hub targets and the 10 core ingredients were less than -5 kcal/mol. Compared with the ALI group, the levels of the respiratory rate, blood lactate, and lung wet/dry weight ratio in ALI+SSY group were significantly decreased (all P<0.01), and the level of ALI score showed a downward trend, but the difference was not statistically significant ( P>0.05). In addition, the levels of interleukin-6, interleukin-1β, and tumor necrosis factor-α in bronchoalveolar lavage fluid and the levels of malondialdehyde, protein carbonyl, and 8-hydroxy-2-deoxyguanosine in lung tissue of rats in ALI+SSY group were significantly decreased in comparison with those in ALI group (all P<0.01). Moreover, compared with the ALI group, the phosphorylation levels of PI3K p85α, AKT1, and GSK3β and the expression level of Nrf2 in lung tissue of ALI+SSY group were significantly up-regulated (PI3K p85α phosphorylation and AKT1 phosphorylation, P<0.01; GSK3β phosphorylation and Nrf2, P<0.05), while the phosphorylation level of NF-κB p65 was significantly down-regulated ( P<0.01). Conclusions:Active ingredients detected from SSY via untargeted Metabolomics can inhibit oxidative stress and inflammation in ALI rats by regulating the PI3K-AKT-GSK3β-Nrf2/NF-κB signaling pathway, thereby alleviating lung lesions.

Objective : To investigate the diagnostic value of combined detection of folate receptor-positive circulat- ing tumor cells ( FR + -CTCs) and hemostatic function indicators in improving the diagnosis of gastrointestinal tumors ( GITs) metastasis． Methods: A retrospective analysis was conducted on the clinical data of 115 patients aged 18 to 80 years who were diagnosed with gastrointestinal tumors via pathology and received treatment，including data on FR + -CTCs，hemostatic function indicators，and pathological staging．The collected data encompassed FR + -CTCs levels，coagulation parameters，and pathological staging．Statistical analysis included t-tests，chi-square tests，fish- er ’s exact test，Logistic regression analysis，and receiver operating characteristic ( ROC) curves to assess the diag- nostic value of combined FR + -CTCs and coagulation parameters in detecting tumor metastasis． Results: FR + -CTCs levels and positive rates demonstrated significant associations with clinicopathological characteristics ( gender，histo- logical type，N staging) in GITs patients ( P＜0. 05) ．In patients with metastasis，elevated fibrinogen levels were observed．Adithonallly，platelet counts showed significant increases in N1 －N3 stages ( P＜0. 05) ．Logistic regres- sion analysis showed that PLT and antithrombin Ⅲ ( AT-Ⅲ) were independent risk factors for GITs metastasis ( P＜0. 05) ． The areas under the ROC curves for predicting GITs metastasis were 0. 678 ( 95% CI: 0. 540 - 0. 816) and 0. 664 ( 95% CI: 0. 512 －0. 815) ，respectively．When combining multiple factors，including FR + - CTCs，PLT，AT-Ⅲ , pathological type，FIB，TT，and gender，for the diagnosis of GITs metastasis，the AUC in- creased to 0. 757 ( 95% CI: 0. 621 －0. 893) ，indicating higher sensitivity and specificity compared to using each indicator alone． Conclusion The combined detection of FR + -CTCs and anticoagulation function indicators has a higher diagnostic value for the diagnosis of GITs，providing a valuable basis for the early diagnosis of GITs，espe- cially in metastasis surveillance．

Background::B-cell maturation antigen (BCMA)-directed chimeric antigen receptor T (CAR-T) therapy yield remarkable responses in patients with relapsed/refractory multiple myeloma (R/RMM). Circulating tumor DNA (ctDNA) reportedly exhibits distinct advantages in addressing the challenges posed by tumor heterogeneity in the distribution and genetic variations in R/RMM.Methods::Herein, the ctDNA of 108 peripheral blood plasma samples from patients with R/RMM at the First Affiliated Hospital, School of Medicine, Zhejiang University was thoroughly investigated before administration of anti-BCMA CAR-T therapy to establish its predictive potential. Flow cytometry is used primarily to detect subgroups of T cells or CAR-T cells.Results::In this study, several tumor and T cell effector-mediated factors were considered to be related to treatment failure by an integrat analysis, including higher percentages of multiple myeloma (MM) cells in the bone marrow ( P = 0.0125), lower percentages of CAR-T cells in the peripheral blood at peak ( P = 0.0375), and higher percentages of CD8 + T cells ( P = 0.0340). Furthermore, there is a substantial correlation between high ctDNA level (>143 ng/mL) and shorter progression-free survival (PFS) ( P = 0.007). Multivariate Cox regression analysis showed that high levels of ctDNA (>143 ng/mL), MM-driven high-risk mutations (including IGLL5 [ P = 0.004], IRF4 [ P = 0.024], and CREBBP [ P = 0.041]), number of multisite mutations, and resistance-related mutation ( ERBB4, P = 0.040) were independent risk factors for PFS. Conclusion::Finally, a ctDNA-based risk model was built based on the above independent risk factors, which serves as an adjunct non-invasive measure of substantial tumor burden and a prognostic genetic feature that can assist in predicting the response to anti-BCMA CAR-T therapy.
