Patients with inflammatory bowel disease (IBD) require long-term pharmacotherapy. Due to the wide variety of clinically available drugs, medication safety has become increasingly concerning. As an indispensable component of pharmaceutical formulations, drug excipients may induce various adverse reactions, including rash, allergic responses, and gastrointestinal discomfort, and may even lead to severe organic injury. However, they are often overlooked in clinical practice. Therefore, identifying and managing excipient-related adverse reactions is crucial for ensuring medication safety. To address this issue, this article systematically reviews common excipients in IBD therapeutics, the underlying mechanisms of excipient-induced adverse reactions, and corresponding management strategies, aiming to enhance clinicians' awareness of excipient-related issues, improve their ability to recognize and manage such reactions, and ultimately ensure patient safety.

This study aimed to establish adult reference intervals for coagulation parameters using the CN-6000 fully automated coagulation analyzer. It also compared the applicability of direct and indirect methods in different populations. A cross-sectional and retrospective design was employed. The direct method included patients from the colorectal surgery and dermatology departments, as well as healthy participants from phase I clinical trials, admitted to the West Campus of China-Japan Friendship Hospital from April to December 2023. Participants were divided into two age groups: younger adults (18-64 years) and older adults (≥65 years). Coagulation parameters were tested, and reference intervals were determined. The indirect method applied the refineR algorithm to analyze coagulation data from non-ICU patients during the same period. The performance of both methods was evaluated in healthy participants, relatively healthy patients, and patients with high disease prevalence. The results showed that the direct method yielded similar reference intervals for APTT, PT, and TT in younger and older groups, with combined intervals of 23.7-31.2 seconds, 10.4-12.8 seconds, and 14.7-17.5 seconds, respectively. However, the Fib showed a significant difference between the two groups ( U=1 052 023, P<0.01), and separate reference intervals were established: 1.7-4.5 g/L for the younger group and 2.1-4.6 g/L for the older group. The reference intervals derived by the indirect method are similar to those from the direct method: APTT 23.8-31.4 seconds, PT 10.4-13.0 seconds, TT 14.5-17.4 seconds, and Fib 1.8-4.3 g/L (18-64 years) and 2.1-4.5 g/L (≥65 years). In relatively healthy patients, the reference intervals obtained by both methods were comparable, but significant differences were observed in patients with high disease prevalence. In conclusion, this study established localized reference intervals for the CN-6000 fully automated coagulation analyzer. The indirect method can serve as an alternative to the direct method in healthy and relatively healthy populations. However, its applicability in populations with high disease prevalence is limited and requires cautious interpretation in the context of clinical settings.

Addressing the enduring challenge of evaluating traditional Chinese medicines (TCMs), the integrated evidence chain-based effectiveness evaluation of TCMs (Eff-iEC) has emerged. This paper explored its capacity through a demonstration study that evaluated the effectiveness evidence of six commonly used anti-hepatic fibrosis Chinese patent medicines (CPMs), including Biejiajian Pill (BP), Dahuang Zhechong Pill (DZP), Biejia Ruangan Compound (BRC), Fuzheng Huayu Capsule (FHC), Anluo Huaxian Pill (AHP), and Heluo Shugan Capsule (HSC), using both Eff-iEC and the Grading of Recommendations, Assessment, Development, and Evaluation (GRADE) system. The recognition of these CPMs within the TCM academic community was also assessed through their inclusion in relevant medical documents. Results showed that the evidence of BRC and FHC received higher assessments in both Eff-iEC and GRADE system, while the assessments for others varied. Analysis of community recognition revealed that Eff-iEC more accurately reflects the clinical value of these CPMs, exhibiting superior evaluative capabilities. By breaking through the conventional pattern of TCMs effectiveness evaluation, Eff-iEC offers a novel epistemology that better aligns with the clinical realities and reasoning of TCMs, providing a coherent methodology for clinical decision-making, new drug evaluations, and health policy formulation.

Objective To construct a model combining with traditional Chinese medicine(TCM)syndrome for predicting the risk of disease progression in patients with idiopathic membranous nephropathy(IMN)by machine learning methods,thus to quantitatively evaluating the value of TCM syndrome in the prediction of the risk of disease progression in IMN.Methods Monofactor analysis,recursive feature elimination(RFE)and multivariate binary Logistic regression analysis were used to screen the independent related factors affecting the risk of disease progression of IMN,and then a risk prediction model was constructed.A total of 102 patients with IMN were randomly assigned to the training set and the test set in a ratio of 65∶35,and then the comparison was conducted in the performance indicators of accuracy,sensitivity,specificity,F1 value,and area under the receiver operating characteristic(ROC)area under the curve(AUC)of the risk prediction model with or without the inclusion of the TCM syndrome information.Results Before the inclusion of TCM syndrome information,12 clinical characteristic variables for patients with MN were obtained after monofactor analysis combined with RFE screening,and they were age,hemoglobin quantification,urinary occult blood,24-hour urine protein quantification,urine protein-creatinine ratio,estimated glomerular filtration rate(eGFR),creatinine,uric acid,alanine transaminase,anti-phospholipase A2 receptor antibody(PLA2R-Ab),total cholesterol,and low-density lipoprotein cholesterd.A risk cholesterol prediction model containing the above variables was constructed.The multivariate binary Logistic regression analysis showed that the differences of the clinical variables mentioned above between the training-set group and test-set group were statistically significant,and the risk prediction model presented good sensitivity and predictability.Monofactor analysis combined with RFE screening was performed again after the inclusion of TCM syndrome information,and then 14 variables were obtained,which included blood stasis syndrome and dampness obstruction syndrome.The sensitivity and specificity of the model with the inclusion of the TCM syndrome information were significantly improved when compared with those without the inclusion of TCM syndrome information.Conclusion The results of the study initially indicate that TCM syndrome can be used as an important supplementary variable for predicting the risk of disease progression in IMN,and will provide a reference for intelligent diagnosis through the integration of traditional Chinese and western medicine information,and will supply the guidance for the treatment of IMN with TCM.
9.Effects of Baicalin on Angiogenesis,Inflammatory Response,and Oxidative Stress in Diabetic Foot Ulcer Rats via Modulation of the HIF-1α/VEGF Signaling Pathway
Journal of Guangzhou University of Traditional Chinese Medicine 2025;42(6):1464-1471
Objective To observe the new therapeutic effects and mechanisms of baicalin on diabetic foot ulcer(DFU)rats.Methods SD rats were randomly divided into a control group,a model group,a low-dose baicalin group,a high-dose baicalin group,and a high-dose baicalin+YC-1[hypoxia-inducible factor 1α(HIF-1α)inhibitor]group.Except for the normal group,the rats in all other groups were constructed to DFU model.After successful modeling,the medication was performed in each group.After treatment,fasting blood glucose level was measured,and the wound healing rate was calculated.Enzyme-linked immunosorbent assay(ELISA)was used to detect the levels of interleukin(IL)-10,tumor necrosis factor(TNF)-α,and IL-6 in wound granulation tissue.The hydroxylamine method was used to measure superoxide dismutase(SOD)activity,the ammonium molybdate method was used to measure catalase(CAT)activity,and the thiobarbituric acid method was used to measure malondialdehyde(MDA)content in wound granulation tissue.Hematoxylin-eosin(HE)staining was used to observe the morphology of wound granulation tissue.Immunohistochemistry was used to detect the positive expression of CD31 protein in wound granulation tissue.Western Blot was used to measure the protein expression levels of advanced glycation end products(AGEs),receptor for advanced glycation end products(RAGE),matrix metalloproteinase 2(MMP-2),HIF-1α,vascular endothelial growth factor(VEGF),and vascular endothelial growth factor receptor 2(VEGFR-2)in wound granulation tissue.Results Compared with the control group,the model group showed reduced angiogenesis and obvious inflanmatory cell infiltration in wound granulation tissue,increased fasting blood glucose level,levels of TNF-α and IL-6,MDA content,and protein expressions of AGEs,RAGE,and MMP-2 in wound tissue,as well as decreased wound healing rate,CD31-positive expression rate,IL-10 level,SOD and CAT activities,and protein expressions of HIF-1α,VEGF,and VEGFR-2,with statistically significant differences(P<0.05).Compared with the model group,the low-and high-dose baicalin groups showed significantly improved wound granulation tissue morphology,reduced fasting blood glucose level,levels of TNF-α and IL-6,MDA content,and protein expressions of AGEs,RAGE,and MMP-2 in wound tissue,as well as increased wound healing rate,CD31-positive expression rate,IL-10 level,SOD and CAT activities,and protein expressions of HIF-1α,VEGF,and VEGFR-2,with statistically significant differences(P<0.05).YC-1 partially reversed the improvement effects of baicalin on angiogenesis and inflammation in DFU rats(P<0.05).Conclusion Baicalin can reduce inflammation and oxidative stress,promote angiogenesis,and accelerate wound healing in DFU rats by activating the HIF-1α/VEGF signaling pathway.

Objective To investigate the causal relationship between abnormal placental lipid metabolism and trophoblast dysfunction in patients with preeclampsia(PE),and to explore the regulatory effects of PPARγ on trophoblast function under hypoxic conditions.Methods Placental tissues were collected from 30 patients with PE and 30 individuals with normal pregnancies at the General Hospital of Ningxia Medical University between October 2020 and November 2021 for the analysis of lipid deposition.A rat model of PE was established,comprising a sham-operated(Sham)group and a reduced uterine perfusion pressure(Rupp)group,with six rats in each group(n=12 total).Human trophoblast cells(HTR-8/SVneo)were cultured in vitro and randomly assigned to four experimental groups:normoxic control,hypoxia,hypoxia+PPARγ agonist(Rosiglitazone),and hypoxia+PPARγ antagonist(T0070907).The expression levels of lipid metabolism-related genes and transcription factors(FASN,FABP4,PPARγ,LXRα)were assessed using RT-qPCR.Western blotting was performed to determine the protein expression levels of PPARγ.Cell migration and invasion capacities were evaluated using scratch wound healing and Transwell assays,respectively.Results Placental lipid deposition in the PE group was significantly higher than that in the control group,particularly in the Rupp model mice(P<0.001).Under hypoxic conditions,the expression levels of FASN and FABP4 were upregulated in trophoblast cells(P<0.001),whereas the expression of PPARγ and LXRα was downregulated(P<0.001).Furthermore,treatment with the PPARγ antagonist T0070907 exacerbated the inhibitory effects of hypoxia on cell function(P<0.001),significantly reducing cell invasion and migration capacity(P<0.001).Additional siRNA-mediated knockdown experiments confirmed that PPARγ deficiency further aggravated hypoxia-induced impairments in cell migration and invasion,and this detrimental effect could not be reversed by Rosiglitazone.Conclusions Abnormal placental lipid metabolism in PE is closely linked to PPARγ-mediated enhancement of lipid synthesis and metabolic dysregulation under hypoxic conditions,which may subsequently impair trophoblast invasion and migration.
