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.

Objective To investigate the expression of targeted regulation of microRNA-146a (miR-146a) on E-box zinc finger protein 1 gene (ZEB1) and its related molecular mechanisms involved in neuroprotection and autophagy inhibition in a rat model of cerebral hemorrhage. Methods Forty 8-week-old male SD rats were randomly divided into four groups: sham operation group, model group, miR-146a overexpression group and miR-146a underexpression group, with 10 rats in each group. Except for the sham operation group, the other three groups were induced to establish an aneurysmal spontaneous intracerebral hemorrhage rat model using type VII collagenase. Rats of four groups were fed a high-salt diet for 6 weeks and euthanized after an additional feeding for 20 weeks. Neurological function [modified neurologic severity score (mNSS)] and brain water content were compared among the four groups. FJC staining was used to detect the number of degenerated neurons; TUNEL staining was used to detect apoptosis; hematoxylin-eosin (HE) staining was used to observe pathological changes in brain tissue; quantitative real-time polymerase chain reaction (qRT-PCR) was used to detect the expression of miR-146a and ZEB1 mRNA; Western blot was used to detect the expression of ZEB1, autophagy-related proteins human recombinant autophagy effector protein (Beclin 1) and microtubule-associated protein 1 light chain 3 (LC3). Results Compared to the sham surgery group, the model group showed a significant increase in mNSS score, brain water content, the number of degenerated neurons and cell apoptosis rate, and the expression level of miR-146a was significantly decreased, while the expressions of ZEB1 mRNA, as well as ZEB1, Beclin 1and LC3 proteins, were significantly increased in the model group (P < 0.05). Compared to the model group, the miR-146a overexpression group exhibited a significant decrease in mNSS score, brain water content, the number of degenerated neurons and cell apoptosis rate, and the expression level of miR-146a was significantly increased, while the expressions of ZEB1 mRNA, as well as ZEB1, Beclin 1 and LC3 proteins were significantly reduced in the miR-146a overexpression group (P < 0.05). Compared to the model group, the miR-146a low-expression group showed a further increase in mNSS score, brain water content, the number of degenerated neurons and cell apoptosis rate, and the expression level of miR-146a was further decreased, while the expressions of ZEB1 mRNA, as well as ZEB1, Beclin 1 and LC3 proteins were further elevated in the miR-146a low-expression group (P < 0.05). Conclusion Upregulating miR-146a can exert neuroprotective effects by targeting and inhibiting ZEB1 gene and protein expression, as well as regulating autophagy activity.

OBJECTIVES: To construct a prognosis risk model based on long noncoding RNAs (lncRNAs) related to cuproptosis and to evaluate its application in assessing prognosis risk of bladder cancer patients. METHODS: RNA sequence data and clinical data of bladder cancer patients were downloaded from the Cancer Genome Atlas database. The correlation between lncRNAs related to cuproptosis and bladder cancer prognosis was analyzed with Pearson correlation analysis, univariate Cox regression, Lasso regression, and multivariate Cox regression. Then a cuproptosis-related lncRNA prognostic risk scoring equation was constructed. Patients were divided into high-risk and low-risk groups based on the median risk score, and the immune cell abundance between the two groups were compared. The accuracy of the risk scoring equation was evaluated using Kaplan-Meier survival curves, and the application of the risk scoring equation in predicting 1, 3 and 5-year survival rates was evaluated using receiver operating characteristic (ROC) curves. Univariate and multivariate Cox regression were used to screen for prognostic factors related to bladder cancer patients, and a prognostic risk assessment nomogram was constructed, the accuracy of which was evaluated with calibration curves. RESULTS: A prognostic risk scoring equation for bladder cancer patients was constructed based on nine cuproptosis-related lncRNAs. Immune infiltration analysis showed that the abundances of M0 macrophages, M1 macrophages, M2 macrophages, resting mast cells and neutrophils in the high-risk group were significantly higher than those in the low-risk group, while the abundances of CD8⁺ T cells, helper T cells, regulatory T cells and plasma cells in the low-risk group were significantly higher than those in the high-risk group (all P<0.05). Kaplan-Meier survival curve analysis showed that the total survival and progression-free survival of the low-risk group were longer than those of the high-risk group (both P<0.01). Univariate and multivariate Cox analysis showed that the risk score, age and tumor stage were independent factors for patient prognosis. The ROC curve analysis showed that the area under the curve (AUC) of the risk score in predicting 1, 3 and 5-year survival was 0.716, 0.697 and 0.717, respectively. When combined with age and tumor stage, the AUC for predicting 1-year prognosis increased to 0.725. The prognostic risk assessment nomogram for bladder cancer patients constructed based on patient age, tumor stage, and risk score had a prediction value that was consistent with the actual value. CONCLUSIONS A bladder cancer patient prognosis risk assessment model based on cuproptosis-related lncRNA has been successfully constructed in this study. The model can predict the prognosis of bladder cancer patients and their immune infiltration status, which may also provide a reference for tumor immunotherapy.

There were 3 cases of distant metastasis and 1 case of recurrence in laparoscopic group, and 2 cases of distant metastasis and 1 case of recurrence in open adrenalectomy group.There was no significant difference in recurrence between the 2 groups ( P=1.000). Conclusions:Compared with open adrenalectomy surgery, laparoscopic adrenalectomy in children has various advantages, including beautiful incision, less trauma and fast recovery.However, it is necessary to select the appropriate cases.

OBJECTIVE: To investigate the expression of DNMT3b in human bladder cancer tissues and its correlation with postoperative survival of patients with bladder cancer. METHODS: Thirty-eight pairs of surgically resected human bladder cancer tissues and adjacent bladder tissues were detected by immunohistochemistry for DNMT3b expression, and the correlations of DNMT3b expression level were analyzed with the patients'age, gender, pathological grade, tumor size, T stage, lymph node metastasis and TNM stages. Kaplan-Meier survival analysis was performed to assess the effect of DNMT3b expression on survival outcomes of the patients. RESULTS: High DNMT3b protein expression was detected in 63.16% of the bladder cancer tissues and in 13.16% of the adjacent tissues ( < 0.05). The expression level of DNMT3b was associated with the pathological grade (=0.002), tumor size ( < 0.001), T stage ( < 0.001), lymphatic metastasis (=0.039) and TNM stage ( < 0.001), but not with gender or age of the patients. Multivariate logistic regression analysis showed that the protein expression level of DNMT3b was correlated with tumor size (=0.008) and TNM grades of the tumor (=0.042). Kaplan-Meier analysis showed that the patients with a high DNMT3b expression had a significantly shorter overall survival than those with a low DNMT3b expression (=0.021). CONCLUSIONS DNMT3b overexpression in bladder cancer is closely related to such clinicopathological factors as pathological grade, tumor size, T stage, lymphatic metastasis, and TNM stage and a shorter overall survival of the patients, suggesting the potential value of DNMT3b as a prognostic marker and a new therapeutic target for bladder cancer.
