ObjectiveTo determine the optimal combination of the effective monomer components "quercetin-kaempferol-abietic acid-boswellic acid" in Fujin Shengjisan for promoting diabetic ulcer （DU） wound healing through uniform design， thereby achieving the modern application of the ancient formula. MethodsFollowing the principle of "uniform design-pharmacodynamic experiment-mathematical modeling and model verification"， the U₁₄（14⁵） uniform design table was adopted.The four monomer components of Chinese medicine were considered as the independent variables， and the proliferation rate of human umbilical vein endothelial cells （HUVECs） induced by glucose was used as the pharmacodynamic indicator. A mathematical model was constructed using DPS software to correlate the effective monomer components with the pharmacodynamic indicator. The results of uniform design were verified through CCK-8 assay， cell scratch healing， tube formation， Western blot， and Real-time PCR. ResultsAmong the 14 compatibility groups， compared with the high-glucose model group， compound compatibility group 6 showed the strongest proliferation effect and statistical significance （P<0.05）. Four quadratic polynomial regression equations （Y₁-Y₄） were obtained through DPS modeling. Considering the model's fit， stability， and practical application， equations Y₁-Y₃ were selected for the follow-up verification. To ensure experiment reproducibility， group 6 was used for validation. Group 6 and equations Y₁-Y₃ were renamed as compound prescription ① to compound prescription④， respectively， to represent the modern application of the ancient FJSJ Powder through compatibility of monomer components. Verification experiments showed that in the CCK-8， scratch healing， and tube formation assays， the cell viability， wound healing rate， and tube formation number of HUVECs stimulated with 50 mmol·L^-1 glucose were significantly reduced compared with the blank group. Moreover， the expression levels of angiogenesis-related cytokines， vascular endothelial growth factor （VEGF） and fibroblast growth factor 2 （FGF2）， and CD31 secretion were significantly down-regulated. However， after intervention with compound prescriptions ① to ④， compound prescriptions ① and ③ significantly improved the biological functions of HUVECs induced by 50 mmol·L^-1 glucose. Further analysis of the regression coefficients of compound prescriptions ① and ③， and the relative dose ratios of each monomer component， indicated that abietic acid， quercetin， and boswellic acid promoted angiogenesis of HUVECs in the high glucose environment， with a major effect （positive partial correlation coefficients， all > 0.9）. Abietic acid and boswellic acid， as well as kaempferol and boswellic acid， promoted angiogenesis in HUVECs through interaction （positive partial correlation coefficients）. ConclusionCompound prescriptions ① and ③ are the optimal combinations. They can reverse the inhibitory effects of high glucose， stimulate the proliferation， migration， and tube formation abilities of HUVECs in a high glucose environment， and promote the expression of vascular endothelial growth factorA（VEGFA）， FGF2， and CD31， thereby promoting angiogenesis and facilitating DU wound healing. This finding not only confirms the good reproducibility and feasibility of compound prescriptions ① and ③ but also provides new insights and methods for the rational construction of mathematical models to further study the compatibility theory of Chinese medicine.

Virus-related lymphoma exhibits a dual nature as both a hematologic malignancy and a viral infectious disease， making it more resistant to treatment and associated with poorer prognosis. This paper analyzes the understanding and therapeutic advantages of traditional Chinese medicine （TCM） in virus-related lymphoma. It proposes a TCM-based approach centered around syndrome differentiation， using standardized measurements of the overall TCM condition， multi-omics research of hematologic tumors， and artificial intelligence technologies to identify the "pre-condition" of virus-related lymphoma. A risk warning model will be established to early identify high-risk populations with viral infections that may develop into malignant lymphoma， thereby establishing a risk warning system for virus-related lymphoma. At the same time， a TCM health management approach will be applied to manage and regulate virus-related lymphoma， interrupting its progression and forming a human-centered， comprehensive， continuous health service model. Based on this， a standardized， integrated clinical prevention and treatment decision-making model for virus-related lymphoma， recognized by both Chinese and western medicine， will be established to provide TCM solutions for primary prevention of major malignant tumors.

Objective: To investigate the distribution of traditional Chinese medicine (TCM) syndromes and syndrome elements in lymphoma, as well as the correlation between TCM syndromes and Western clinical indicators, in order to analyze associations between TCM syndromes and these indicators. Methods: From January 2023 to May 2024, 216 patients with lymphoma who met the inclusion criteria in the Department of Hematology, Third People′s Hospital Affiliated to Fujian University of Traditional Chinese Medicine were enrolled. Four diagnostic methods were applied to perform TCM syndrome differentiation and extract syndrome elements. The correlations between various syndromes and blood test indicators of lactate dehydrogenase (LDH), β2-microglobulin (β2-MG), immunoglobulin G (IgG), immunoglobulin M (IgM), immunoglobulin A (IgA), white blood cell (WBC), hemoglobin (Hb), platelet count (PLT), neutrophil (NEUT), immunohistochemical markers of B-cell lymphoma-6 (BCL6), B-cell lymphoma-2 (BCL2), proto-oncogene MYC, and Ki67 protein expression, Ann Arbor staging, international prognostic index (IPI) score, bone marrow infiltration, concurrent infections during chemotherapy, and post-chemotherapy bone marrow suppression rate were analyzed. Results: Five TCM syndromes, ranked by frequency, were syndromes of yin deficiency with phlegm accumulation(41.67%), qi depression with phlegm obstruction(30.56%), cold-phlegm congelation and stagnation(12.96%), phlegm-blood stasis toxin(12.04%), and lingering pathogen due to deficient vital qi(2.77%). Yin deficiency(50.93%) and phlegm(45.37%) were the more prevalent syndrome elements. The TCM syndromes were correlated with β2-MG, PLT, MYC, BCL2/MYC, Ki67 protein expression, and bone marrow infiltration (P<0.05). No statistically significant differences were observed in Ann Arbor staging or IPI score across the syndromes. Compared to the syndrome of cold-phlegm congelation and stagnation, the syndrome of qi depression with phlegm obstruction exhibited higher levels of NEUT, MYC, BCL2/MYC, and Ki67 protein expression, as well as a higher rate of post-chemotherapy bone marrow suppression (P<0.05); the syndrome of phlegm-blood stasis toxin showed higher MYC and BCL2/MYC protein expression and a higher rate of post-chemotherapy bone marrow suppression rate (P<0.05); the syndrome of yin deficiency with phlegm accumulation demonstrated higher MYC and BCL2/MYC protein expression and bone marrow infiltration rates, whereas PLT level was lower (P<0.05); the syndrome of lingering pathogen due to deficient vital qi had higher MYC, BCL2/MYC, and Ki67 protein expression levels, as well as a higher rate of post-chemotherapy bone marrow suppression rate (P<0.05). Compared to the syndrome of qi depression with phlegm obstruction, the syndrome of phlegm-blood stasis toxin exhibited lower Ki67 protein expression (P<0.05); the syndrome of yin deficiency with phlegm accumulation had higher β2-MG level, bone marrow infiltration rate, and rate of concurrent infections during chemotherapy, whereas PLT and NEUT levels and the rate of post-chemotherapy bone marrow suppression rate were lower (P<0.05). Compared to the syndrome of phlegm-blood stasis toxin, the syndrome of yin deficiency with phlegm accumulation had higher β2-MG level, whereas NEUT and the rate of post-chemotherapy bone marrow suppression were lower(P<0.05); the syndrome of lingering pathogen due to deficient vital qi exhibited a higher Ki67 protein expression (P<0.05). Compared to the syndrome of yin deficiency with phlegm accumulation, the syndrome of lingering pathogen due to deficient vital qi also showed a higher Ki67 protein expression(P<0.05). Conclusion The syndrome of yin deficiency with phlegm accumulation is relatively common in lymphoma. There is a correlation between TCM syndromes and Western medicine clinical indicators. The presence of heat signs in the syndromes may indicate active disease and poor prognosis, while the presence of strong pathogenic factors and weak vital qi in the syndromes may indicate a severer chemotherapy-related bone marrow suppression.

ObjectiveA qualitative analysis method was established for the composition of Astragali Radix（AR） before and after rice stir-frying. On the basis of systematic characterization of the chemical compositions in AR and stir-fried AR with rice（ARR）， the structures of their major compounds were deduced and identified， and the differential compositions between them were analyzed. MethodsUltra performance liquid chromatography-quadrupole-time-of-flight mass spectrometry（UPLC-Q-TOF-MS/MS） was used to detect the samples of AR and ARR in positive and negative ion modes， respectively. The compounds were analyzed and identified through self-constructed databases， literature， and reference standards， etc. And the data were analyzed by chemometrics， in order to screen for the differential components between AR and ARR. ResultsA total of 123 compounds were identified in AR and ARR， including 41 flavonoids， 19 terpenoids， 26 organic acids， 8 amino acids， 5 nucleotides， 5 carbohydrates and 19 other compounds. Among them， there were 95 common components in both， 18 unique components in AR， and 10 unique components in ARR. Principal component analysis（PCA） and orthogonal partial least squares-discriminant analysis（OPLS-DA） results both showed that there were significant differences in the chemical constituents of AR before and after rice stir-frying， and a total of 26 constituents with differences in the content were screened out， including L-canavanine， L-pyroglutamic acid， L-phenylalanine， cis-caffeic acid， and malonylastragaloside Ⅰ. Among them， 19 constituents of ARR were down-regulated and 7 constituents were up-regulated by comparing with AR. ConclusionThis study clarifies that the chemical composition of AR and ARR is mainly composed of flavonoids， terpenoids， and organic acids， and analyzes the components with significant differences in content between the two in combination with chemometrics， and the differential components are dominated by amino acids， organic acids and terpenoids， which can provide reference for the subsequent quality control and material basis research.

AIM: To compare the efficacy of different intraocular lens(IOL)fixation in aphakic patients lacking capsule support.METHODS:Retrospective study. Totally 120 cases(120 eyes)of aphakia patients who lacked capsule support admitted to our hospital from June 2019 to June 2024 were selected as the study subjects and randomly assigned into group A and group B, with 60 cases in each group. Group A underwent subcapsular IOL deep scleral fixation, while group B underwent IOL suture suspension fixation in the ciliary groove. The surgery time, uncorrected visual acuity(UCVA), best corrected visual acuity(BCVA), intraocular pressure(IOP), corneal endothelial cell density(CECD), corneal endothelial cell loss rate, and postoperative complications were compared between the two groups before and at 1, 3, 6 mo after surgery.RESULTS:The operation time of the group A was lower than that of the group B(24.69±2.69 vs. 32.75±3.75 min, t=11.937, P<0.05). The UCVA and BCVA in both groups were better than those before operation, and the group A was better than the group B(all P<0.05). The loss rates of corneal endothelial cells in the group A were lower than those in the group B at 1, 3 and 6 mo after surgery, the IOP in the group A was lower than that in the group B at 1 mo after surgery, and the CECD in the group A was higher than the group B(all P<0.05). The 3 eyes(5.0%)of the postoperative IOL ectopic in the group A were less than 11 eyes in the group B(18.3%, P=0.023).CONCLUSION:Subcapsular IOL deep scleral fixation has prominent curative effects on aphakic patients who lack capsule support. It helps improve vision, with less operation time, and fewer postoperative complications.

This study examined the impact of astragalus polysaccharide synbiotics on fecal scores and blood indices in calves suffering from E.coli-induced diarrhea.Twenty Holstein calves,aged 6-9 days and weighing approximately(44.56±5)kg,were randomly divided into a control group and an experimental group.The experiment lasted 10 days.Both control and experimental group calves received daily intramuscular injections of borlococci(1 mg/kg)and enrofloxacin(20 mg/kg)dur-ing experimental period.In addition to the standard treatment regimen,calves in the experimental group were given 20 g of Astragali polysaccharide synbiotics in their milk each day.Fecal scoring was conducted daily at 9:00 a.m.,and jugular blood was collected at the end of experiment to eval-uate relevant blood parameters.Results indicated a 17％reduction in diarrhea rates in the experi-mental group compared to the control group,although there was no statistically significant differ-ence in fecal scores.Compared to the control group,the experimental group showed a significant in-crease in the levels of immunoglobulin A(IgA)and immunoglobulin M(IgM)by 54.81％and 60.40％,respectively(P＜0.01).Immunoglobulin G(IgG)and interleukin-10(IL-10)levels increased by 50.89％and 46.80％,respectively(P＜0.05).while interleukin-6(IL-6),interleukin-1β(IL-1 β),and tumor necrosis factor-α(TNF-α)decreased by 28.99％,20.88％,and 37.10％,re-spectively(P＜0.01).The experimental group showed a significant reduction in the level of D-lac-tic acid(D-LA)and endotoxin(LPS)by 47.46％and 65.31％compared to the control group,re-spectively(P＜0.01),and diamine oxidase(DAO)activity was 30％lower(P＜0.01).Total su-peroxide dismutase(T-SOD)content increased by 12.78％(P＜0.05),and catalase(CAT)and glutathione peroxidase(GSH-Px)contents increased by 53.09％,and 60.57％,respectively(P＜0.01).Furthermore,malondialdehyde(MDA)content decreased by 33.29％(P＜0.01)in the ex-perimental group.In conclusion,administering astragalus polysaccharide synbiotics could reduce in-testinal mucosal damage in calves with E.coli diarrhea,enhance their immunity and antioxidative stress response,and mitigate the impact of pathogenic bacteria and oxidative stress on intestinal mucosal permeability.

In this study,freeze-drying methods was used to prepare astragalus polysaccharide synbi-otic powder.The optimized freeze-dried protective agent formulation using response surface meth-odology in this study was 17.99％skimmed milk powder,7.26％sucrose,8.04％galactooligosac-charides,and 9.64％astragalus polysaccharide,and the remaining amount was distilled water.The survival rate of lactic acid bacteria in the prepared bacterial powder was 88.06％.A calf feeding ex-periment was conducted over 28 days with thirty healthy newborn calves with similar age,the calves were randomly assigned to either control group and the astragalus polysaccharide synbiotic group,each comprising 15 calves.The astragalus polysaccharide synbiotic group received a supple-ment of astragalus polysaccharide in addition to their regular feed.Compared to the control group,the results showed that:(1)Astragalus polysaccharide synbiotics significantly increased the aver-age daily gain(ADG)of calves and decreased the fecal score and diarrhea rate in calves.(2)By tes-ting the immunological indexes,we found that astragalus polysaccharide synbiotics significantly in-creased the serum level of IgA,IgG,IgM,IL-2 and IL-10,and decreased the level of IL-6 and TNF-α.(3)Astragalus polysaccharide synbiotics notably enhanced the Chao1,Sobs,and Shannon indi-ces,while reducing the Simpson index.At the phylum level,astragalus polysaccharide synbiotics group showed a significant increase in the relative abundance of Cyanobacterium and Firmicutes,and a decrease in Proteobacteria.At the genus level,the relative abundance of Esche-richia-Shigella in astragalus polysaccharide synbiotic group significantly decreased.Whereas norank_f__norank_o__Clostridia_UCG-014 and Butyricicoccus significantly increased.In conclu-sion,this study successfully formulated an astragalus polysaccharide synbiotic powder.The powder can significantly promote the growth of calves,enhance immune function,improve the structure of gut microbiota,and reduce the incidence of calf diarrhea.

Objective:To explore the prognostic value of systemic immune-inflammatory index(SII)combined with tumor burden score (TBS) (hereinafter referred to as STS) in patients with intrahepatic cholangiocarcinoma (ICC) after radical resection, and to construct a nomogram model.Methods:The clinical data (including the degree of tumor differentiation, vascular cancer thrombus, and lymph node metastasis, etc.) of 258 ICC patients who received radical resection at People′s Hospital of Zhengzhou University (170 cases, training set) and Cancer Hospital of Zhengzhou University (88 cases, validation set) from January 1, 2016 to January 31, 2020 were retrospectively analyzed and graded by SII, TBS and STS. Multivariate Cox regression analysis were used to identify independent factors affecting the prognosis of patients with ICC. Kaplan-Meier survival curve and receiver operating characteristic curve (ROC) were drawn to evaluate the predictive efficiency of SII, TBS and STS in the overall survival of patients with ICC after radical resection. The nomogram prediction model was constructed and evaluate the performance of nomogram model using consistency index (C-index) and calibration curve.Results:Among 170 ICC patients in the training set, there were 106 cases of SII grade 1 and 64 cases of SII grade 2; 137 cases of TBS grade 1 and 33 cases of TBS grade 2; and 98 cases of STS grade 1, 47 cases of STS grade 2, and 25 cases of STS grade 3. Among 88 ICC patients in the validation set, there were 33 cases of SII grade 1 and 55 cases of SII grade 2; 66 cases of TBS grade 1 and 22 cases of TBS grade 2; and 30 case of STS grade 1, 39 cases of TBS grade 2, and 19 cases of TBS grade 3.The multivariate Cox regression analysis showed that tumor differentiation degree (highly differentiated vs. moderately differentiated HR=0.157, 95% confidence interval(95% CI) 0.045 to 0.546, highly differentiated vs. poorly differentiated HR=0.452, 95% CI 0.273 to 0.750), STS (grade 3 vs. grade 2 HR=1.966, 95% CI 1.148 to 3.469; grade 3 vs. grade 1 HR=1.405, 95% CI 0.890 to 2.216), vascular cancer thrombus ( HR=2.006, 95% CI 1.313 to 3.066), nerve invasion ( HR=1.865, 95% CI 1.221 to 2.850), and lymph node metastasis ( HR=1.802, 95% CI 1.121 to 2.896) were independent influencing factors of overall survival in ICC patients after radical resection (all P<0.05). The Kaplan-Meier survival curve showed that SII, TBS, and STS were independent influencing factors of overall survival in ICC patients (all P<0.05). The results of ROC analysis showed that the areas under the curve of SII, TBS and STS in predicting overall survival of ICC patients after radical resection were 0.566 (95% CI 0.479 to 0.652), 0.585 (95% CI 0.499 to 0.672), and 0.657 (95% CI 0.522 to 0.692), respectively. Tumor differentiation, vascular tumor thrombus, nerve invassion, lymph node metastasis, and STS were included to constract the nomogram model. The C-indexes of the training set and validation set based on the nomogram model were 0.792 (95% CI 0.699 to 0.825) and 0.776 (95% CI 0.716 to 0.833), respectively. The calibration curves of the survival rate of the training set and the validation set were close to the reference lines, and the nomogram model had better predictive ability in both the training set and the validation set. Conclusions:Preoperative STS grading is an effective and practical predictor of overall survival in ICC patients after radical section. Compared with SII and TBS alone, it has better predictive value for the prognosis of patients with ICC.
