The general models for intermediates quality analysis in the production process of Yaobitong capsule were established by near infrared spectroscopy (NIRS) combined with chemometrics, realizing the rapid determination of notoginsenoside R1, ginsenoside Rg1, ginsenoside Re, ginsenoside Rb1, ginsenoside Rd and moisture. The spray-dried fine powder and total mixed granule were selected as research objects. The contents of five saponins were determined by high performance liquid chromatography and the moisture content was determined by drying method. The measured contents were used as reference values. Meanwhile, NIR spectra were collected. After removing abnormal samples by Monte Carlo cross validation (MCCV), Monte Carlo uninformative variables elimination (MC-UVE) and competitive adaptive reweighted sampling (CARS) were used to select feature variables respectively. Based on the feature variables, quantitative models were established by partial least squares regression (PLSR), extreme learning machine (ELM) and ant lion optimization least squares support vector machine (ALO-LSSVM). The results showed that CARS-ALO-LSSVM model had the optimum effect. The correlation coefficients of the six index components were greater than 0.93, and the relative standard errors were controlled within 6%. ALO-LSSVM was more suitable for a large number of samples with rich information, and the prediction effect and stability of the model were significantly improved. The general models with good predicting effect can be used for the rapid quality determination of Yaobitong capsule intermediates.

Systemic lupus erythematosus （SLE）， a refractory autoimmune disease， is among the dominant diseases where traditional Chinese medicine （TCM） shows advantages in the field of rheumatology and immunology. The China-Japan Friendship Hospital hosted the "46^th Youth Salon on Dominant Diseases （Systemic Lupus Erythematosus）" organized by the China Association of Chinese Medicine， which led to a consensus on "the advantages， challenges， interdisciplinary approaches， and translational achievements of integrated TCM and Western medical approaches in the diagnosis and treatment of SLE." The diagnosis and treatment of SLE currently face several challenges， such as frequent misdiagnosis and missed diagnosis in the early stages， difficulty in achieving treatment targets， multiple side effects from pharmacotherapy， and the lack of management strategies for special populations， all of which hinder the fulfillment of the clinical needs of patients. Integrated TCM and Western medical approaches can improve clinical symptoms such as skin erythema， aversion to cold and cold limbs， fatigue， dry mouth， restlessness， and heat sensation in the palms and soles， thereby improving patients' quality of life. The approaches also help consolidate the efficacy of conventional Western medicine， slow disease progression， reduce relapse rates， address multi-organ involvement， and prevent or treat complications. Additionally， they enhance efficacy and reduce toxicity， prevent the side effects of Western medications， help reduce hormone use， and offer distinct advantages in the individualized intervention of special populations， contributing to the whole-process management of the disease. However， evidence-based medical support for this integrated approach remains limited， and the quality of available evidence is generally low. Common evaluation systems and modern research methodologies should be adopted to clarify the efficacy of TCM in SLE treatment. Efforts should be made to carry out high-quality evidence-based medical research， strengthen the development of fundamental and pharmacological research， and further explain the distinct advantages of TCM in the diagnosis and treatment of SLE. Future efforts should focus on advancing the integration of TCM and modern medicine， incorporating multi-omics technologies， individualized stratification， and other precision medicine concepts， in combination with artificial intelligence. Moreover， interdisciplinary collaboration should be promoted to utilize modern technology in exploring the essence of TCM theories and screening effective formulae， thereby comprehensively improving the diagnosis and treatment of SLE through integrated TCM and Western medical approaches.

Objective: To explore the key factors affecting the selection and effectiveness of bladder management modalities in patients with spinal cord injury，so as to provide reference for the optimization of individualized bladder management strategies. Methods: The clinical and follow-up data of 78 patients with spinal cord injury treated in our hospital during Jan.1,2013 and Dec.31,2022 were retrospectively analyzed.The distribution of bladder management modalities among different grades of injuries was analyzed. Bowker symmetry test was used to evaluate the difference between bladder management modalities at discharge and at the end of follow-up. Multiple linear regression was used to explore the influencing factors of bladder management effects. Plotting Kaplan-Meier survival curves were adopted to calculate the median time of changes in bladder management. Results: At discharge，there were 9 cases of self-catheterization，19 cases of intermittent catheterization，22 cases of reflexive voiding，26 cases of long-term catheterization，and 2 cases using urinary collector.At the end of follow-up，there were 15 cases of self-catheterization，8 cases of intermittent catheterization，34 cases of reflexive voiding，14 cases of long-term catheterization，and 7 cases using urinary collector.There was a significant difference between the modalities of bladder management at discharge and at the end of follow-up (χ =21.43，P=0.018).Multiple linear regression showed a significant decrease of 8.60 in the total neurogenic bladder symptom score (NBSS) for grade D injuries compared with grade A injuries (P=0.026). The median time to bladder management change was 7.93 months (95%CI:5.44-9.44), with approximately 50% of patients experiencing a change in bladder management within 8 months after discharge. Conclusion: The modalities of bladder management changed significantly after discharge.The grade of injury was a key factor affecting the effectiveness of bladder management.Higher grade was associated with worse effectiveness of bladder management.

Aim To investigate the dynamic time-course changes in neuronal cytoskeleton after acute ischemia and reperfusion in rats. Methods Reperfusion was performedin rats by blocking the middle cerebralarteryfor 90 min, then therats wereobserved and collected at different time points. The brain damage wasobserved by Nissl staining,and neurobehavioural function was evaluated with neurological deficit score and forelimb placement test. The cellular changes in the alternations of cytoskeletal elements including microtubule associated protein 2 (MAP2) and neurofilament heavy chain (NF-H) were observed by immunohistochemistry staining and Western blot. Impaired axons, dendrites and cytoskeletal alternations were detected by electron microscope. Results Brain damage and neurobehavioural function were gradually aggravated with the prolongation of reperfusion. Brain damage appeared earlier and more severe in striatum than in cortex. Moreover, decreased MAP2-related and increased NF-H-related immunoreactive intensities were found in the ischemic areas. Impaired cytoskeletal arrangement and reduced dense were indicated. Damaged cytoskeletal components such as microtubules and neurofilament arrangement, decreased axonal filament density, and swelled dendrites were observed after cerebral ischemia reperfusion by ultrastructural observations. Conclusions Different brain regions have diverse tolerance to ischemia-reperfusion injury. Major elements of neuronal cytoskeleton show dynamic responses to ischemia and reperfusion, which may further contribute to brain damage and neurological impairment following MCAO and reperfusion.

Aim To analyze the anti-A549 and HI299 lung ade-nocarcinoma activities via using examples of baicalin, astragalo-side, hesperidin and cisplatin based on real time cellular analysis (RTCA) technology, and to build a new strategy for EC50 e-valuation reflecting the time-dimensional characteristic. Methods Using RTCA Software Pro for data analysis and GraphPad Prism and Origin Pro plotting, the in vitro anti-A549 and H1299 lung adenocarcinoma activities of baicalin, astragaloside, hesperidin, and cisplatin were characterized using the endpoint method and time dimension, respectively. Results (X) There were significant differences in EC50 values of A549 and H1299 cells at 24 h and 48 h endpoint methods. (2) The correlation coefficient of the curve fitted with the four-parameter equation was > 0. 9, and the dynamic change of EC50 remained relatively stable (the linear fitting of EC50 at adjacent 4 points I slope 1^1) used to calculate the EC50 value within this time dimension. The EC50 of baicalin, astragaloside, hesperidin and cisplatin on A549 cells was 52. 97 ±1.75 плпо! • L~1(16~48 h) , 62.88 ± 2.91 ijunol • L"1 (32.25 -48 h) , 78.84 ±0.33 плпо1 • L"1 (21.5 -29.75 h), 13.57 ±1.54 плпо1 • L_1(27.5 -48 h), respectively; the EC50 of baicalin, astragaloside, hesperidin and cisplatin on H1299 cells was 43. 71 ± 1. 26 |лто1 • L_1 ( 19. 5 -48 h), 47.23 ±1. 19 |лто1 • L_1(14 -48 h) , 39.45 ±0.24 плпо1 • L"1 (12.75 -46.25 h), 25.97 ±4.76 плпо1 • L"1 (10. 25 -48 h) , respectively. The results showed that the time window for the anti-tumor effect of the test solution/drug was different. Conclusions Based on RTCA technology, it is more accurate and reasonable to select EC50 data that exhibit better fitting, stable changes, and time-dimensional characteristics for the evaluation of anti-tumor activity. In addition, this method of distinguishing different effective time of antitumor drugs can provide a reference for the timing of clinical combination drugs, and this approach will also provide a reference for further related studies.

Objective To investigate whether Liuwei Dihuang Pills enhances the antigen cross-presenting ability of dendritic cell(DC)by increasing gap junctional intercellular communication(GJIC),and to explore the mechanisms involved.Methods Western Blot and immunofluorescence were used to observe the effects of Liuwei Dihuang Pills-containing serum on the expression and membrane localisation of gap junction protein connexin43(Cx43)in mouse melanoma cells(B16);Calcein-AM/DiI fluorescence tracer assay was used to observe the effects of Liuwei Dihuang Pills-containing serum on the function of GJIC in B16 cells;flow cytometry was used to observe the role of GJIC in the enhancement of DC antigen presenting ability by Liuwei Dihuang Pills-containing serum;and propidium iodide(PI)/Hoechst staining assay was used to observe the immunocidal effect of CD8+ T-lymphocytes.Results Western Blot and immunofluorescence experiments showed that Liuwei Dihuang Pills-containing serum led to the up-regulation of Cx43 expression;fluorescence tracer experiments proved that the GJIC function of B16 cells was significantly enhanced by Liuwei Dihuang Pills-containing serum;flow cytometry analyses showed that the DC antigen-presenting ability was enhanced by Liuwei Dihuang Pills-containing serum;and the results of PI/Hoechst staining showed that the immuno-killing effect of CD8+T-cells was more significant after the intervention of Liuwei Dihuang Pills-containing serum in B16-OVA.Conclusion Liuwei Dihuang Pills improve the GJIC function by up-regulating the Cx43 expression of melanoma cells,and then enhance the cross-presenting ability of DCs thus activating stronger CD8+ T-cell immunocidal responses.

Objective To investigate the ameliorative effect of sulforaphane on inflammatory response and airway remodeling in rats with chronic obstructive pulmonary disease(COPD).Methods Seventy-five SD rats were randomly divided into the normal group,the model group,and the low-,medium-,and high-dose groups of sulforaphane,with 15 rats in each group.Except for the normal group,the COPD model was prepared in the remaining group using aroma smoke inhalation combined with intratracheal droplet lipopolysaccharide(LPS)method.After the successful modelling,the rats were administered the drug by gavage for 28 days.At the end of the administration,the general conditions of the rats in each group were observed,and the lung function[forced vital capacity(FVC),peak expiratory flow-rate(PEF),forceful expiratory volume in 1 second(FEV1)]was examined,and the pathological changes of the lung tissues were observed by hematoxylin-eosin(HE)staining method,and the indexes of airway remodeling(thickness of the bronchial wall,thickness of the smooth muscle)were measured;the enzyme-linked immunosorbent assay(ELISA)was used to examine the lung function of the rats.The levels of inflammatory factors[tumor necrosis factor α(TNF-α),interleukin 1β(IL-1β)]were detected in lung tissue by enzyme-linked immunosorbent assay(ELISA),and changes in the protein expressions of Toll-like receptor 4(TLR4),myeloid differentiation factor 88(MyD88),and nuclear transcription factor κB(NF-κB)were detected in lung tissue by Western Blot.Results(1)The rats in the model group had dry and lack of glossy fur,obvious coughing and nose scratching,shortness of breath,slow movement,and preferred to arch their backs and lie curled up;the rats in the low-,medium-and high-dose groups of sulforaphane showed significant improvement in shortness of breath,coughing,and other abnormal manifestations.(2)HE staining showed that the airway wall and smooth muscle of rats in the model group were thickened,the airway epithelium was damaged,and alveolar destruction,fusion,and massive infiltration of inflammatory cells were seen;the histopathological changes in the lungs of rats in the low-,medium-and high-dose groups of sulforaphane improved to varying degrees,with the airway wall becoming thinner,the degree of alveolar destruction being reduced,and the infiltration of inflammatory cells being reduced.(3)Compared with the normal group,FVC,PEF and FEV1 were significantly reduced in the model group(P＜0.05),and the levels of TNF-α and IL-1β,bronchial wall thickness,smooth muscle thickness,and the expression levels of TLR4,MyD88 and NF-κB were significantly increased in the model group(P＜0.05);and in comparison with the model group,the levels of FVC,PEF,and FEV1 were significantly increased in the rats in the sulforaphane low-,medium-,and high-dose groups(P＜0.05),and the levels of TNF-α,IL-1β,bronchial wall thickness,smooth muscle thickness,and the expression levels of TLR4,MyD88,and NF-κB were significantly decreased(P＜0.05)compared with the model group.Conclusion Sulforaphane helps to inhibit the inflammatory response,attenuate airway remodeling,and improve the pathological injury and lung function of lung tissue in rats with COPD,and its mechanism may be related to the inhibition of TLR4,MyD88,and NF-κB protein expressions.

Objective To preliminarily analyze the influencing factors of benign thyroid nodule malignant transformation and provide a basis for early intervention of benign thyroid nodule malignant transformation. Methods Selected 158 patients with benign thyroid nodules who visited our hospital from January 2019 to January 2022 for inclusion in the study, and followed up for 3 year to observe whether the nodules had malignant changes. The age, gender and dietary habits were collected. 3 mL of fasting venous blood of subject were collected , and the level of TT3, TT4, FT3, FT4, TSH, TgAb, CEA, thyroglobulin and calcitonin were collected. Results The results of this study suggest that the plasma levels of serum TgAb, TSH, TT4, TT3, FT3, FT4, CEA, thyroglobulin, and calcitonin of subjects were not statistically significant between sexes. The results of univariate analysis showed that compared with non malignant group, the patients in malignant nodule group were younger, the longest diameter of nodule was smaller, TgAb level was higher, TSH level was higher, FT3 level was lower, the proportion of internal calcification was higher, thyroglobulin level was higher, CEA level was higher, calcitonin level was higher, and the proportion of abnormal lipid metabolism and glucose metabolism was also higher, which was statistically significant (P<0.05). Multivariate logistic regression analysis showed that TgAb positive, internal calcification, increased carcinoembryonic antigen level, dyslipidemia, elevated thyroglobulin level, and abnormal glucose metabolism, elevated calcitonin level were associated with the increased risk of node canceration, and increased total FT3 level was associated with the reduced risk of canceration (P<0.05). Conclusion TgAb positive, internal calcification, increased carcinoembryonic antigen level, small nodule diameter, abnormal blood lipids, elevated thyroglobulin level, low total FT3 level, abnormal glucose metabolism, and elevated calcitonin level are associated with the increased risk of malignant transformation of benign thyroid nodules, which should be paid attention to clinically.

Guidance implementation acts as a bridge between theory and practice，enabling the rapid expansion of their impact and application. This study demonstratively evaluated emergency health systems guidance documents （HSG），represented by the COVID-19 emergency HSG，based on the item implementability of the Appraisal of Guidelines for Research and Evaluation-Health Systems （AGREE-HS），aiming to explore the characteristics of implementability in emergency HSG. The evaluation results indicated that the COVID-19 emergency HSG had a low mean score in implementability，which ranked just above the item participants. Criterion 2 （costs and resource considerations for implementing the recommendations） received the highest mean score of 4.29，while criterion 9 （systematic evaluation of implementation） received the lowest mean score of 1.34. The emergency HSG formulated by the World Health Organization（WHO） and those formulated by various countries showed no difference （P=0.114） in criterion 1 （barriers and facilitators to implementation） but had differences （P<0.05） regarding the average item scores and the scores of the remaining criteria. The WHO standard HSG had high overall scores and had differences （P<0.05） in both the mean item scores and the scores of the nine criteria when compared with the emergency HSG. The global/national HSG showed differences in scores of criterion 1 （barriers and facilitators to implementation） compared with the both clinically relevant HSG and material support HSG （P<0.05）. Emergency HSG prioritized considerations of implementation costs，resources，and flexibility in terms of implementability，while de-emphasizing aspects such as stakeholder opinions，dissemination strategies，and evaluation of HSG. This may be attributed to the context in which emergency HSG are formulated，given the inherent flexibility and variability of emergency health events. The developers should comprehensively consider the needs and characteristics related to the implementability of emergency HSG during the formulation process.
