OBJECTIVE To provide a scientific basis for the quality evaluation and clinical application of Qingwen hufei granules. METHODS Fourteen batches of Qingwen hufei granules were used as samples to establish high-performance liquid chromatography (HPLC) fingerprints using the Similarity Evaluation System for Chromatographic Fingerprint of Traditional Chinese Medicine (2012 Edition). The chromatographic peaks were identified and the similarity was evaluated. Cluster analysis (CA), principal component analysis (PCA), and orthogonal partial least squares-discriminant analysis (OPLS-DA) were used to conduct chemical pattern recognition analysis on the 14 batches of samples. Meanwhile, the contents of neochlorogenic acid (NGA), chlorogenic acid (CHA), cryptochlorogenic acid (CGA), forsythoside A (FTA), 3,5-O-dicaffeoylquinic acid (3,5-O- DA), 4,5-O-dicaffeoylquinic acid (4,5-O-DA), and angoroside C (AGC) in the samples were determined by HPLC. RESULTS The methodological investigation results of both the fingerprint and the content determination complied with the relevant requirements. Fourteen common peaks were indicated in the HPLC fingerprints of the 14 batches of samples, and 7 of them were identified [NGA (peak 2), CHA (peak 3), CGA (peak 5), FTA (peak 11), 3,5-O-DA (peak 12), 4,5-O-DA (peak 13), and AGC (peak 14)]; the similarity of each sample was greater than 0.94. The results of CA and PCA showed that the samples could be classified into 3 categories; the results of OPLS-DA indicated that peak 4 (unknown), peak 11 (FTA), peak 8 (unknown), peak 9 (unknown), and peak 1 (unknown) were the differential components. The content ranges of NGA, CHA, CGA, 3,5-O-DA, FTA, 4,5-O-DA and AGC in the 14 batches of samples were 0.210 4-0.458 7, 0.269 1-0.506 3, 0.228 1-0.461 1, 0.443 9-1.044 6, 0.066 7-0.155 7, 0.062 8-0.143 8, and 0.057 4-0.105 7 mg/g, respectively. CONCLUSIONS The HPLC fingerprint and multi-component content determination methods established in this study are efficient and reliable, and can be used for the quality evaluation of Qingwen hufei granules.

Irritable bowel syndrome with diarrhea (IBS-D), as a prototypical disorder involving the microbiota-gut-brain axis, remains poorly understood in terms of its pathogenesis, posing ongoing challenges for clinical diagnosis. Omics technologies, leveraging their high-throughput detection and systematic analysis advantages, has emerged as a critical tool for deciphering the complex mechanisms underlying traditional Chinese medicine (TCM) treatment of IBS-D. This systematic review summarizes the research progress of transcriptomics, proteomics, metabolomics, microbiomics, and multi-omics integration techniques in TCM interventions for IBS-D. In single-omics studies, transcriptomics using techniques like RNA-seq, reveals the regulatory mechanisms of TCM on IBS-related signaling pathways. Proteomics, leveraging quantitative technologies such as 2D-difference gel electrophoresis and tandem mass tag, identifies differentially expressed proteins and elucidates the action targets of TCM in treating IBS-D. Metabolomics, employing methods like UPLC-Q-TOF-MS and LC-MS/MS, discovers metabolic pathways regulated by TCM to improve metabolic disturbances in IBS-D. Microbiomics, based on 16S rRNA sequencing, confirms that TCM can reshape the gut microbiota structure and restore the intestinal microecological balance, thereby improving IBS-D. Multi-omics integration further overcomes the limitations of single-omics approaches by synthesizing information from transcriptomics, proteomics, metabolomics, and microbiomics, enabling a more comprehensive and systematic elucidation of the complex mechanisms underlying TCM treatment for IBS-D. In the future, research related to IBS-D should be advanced from three aspects: stratified clinical research based on TCM syndrome types, multi-omics integration verification mechanisms, and emerging omics to explore new mechanisms, providing more innovative ideas for the precise diagnosis and treatment of this disease.

OBJECTIVE To confirm trigger items for adverse drug reaction (ADR) induced by bevacizumab, to identify and analyze the occurrence of related ADR, and to establish a predictive model for severe adverse reaction (SAR) caused by this drug. METHODS Based on the global trigger tool (GTT) theory, and referencing the GTT White Paper, drug package inserts and relevant literature, trigger items for bevacizumab-related ADR were confirmed using a single-round Delphi method. Utilizing these established items, electronic medical records of relevant patients at Guilin People’s Hospital from January 2020 to September 2024 were actively screened via the China Hospital Pharmacovigilance System. Pharmacists then identified and tallied the occurrence of bevacizumab-induced ADR. Data from patients with any positive trigger item served as the study subjects (divided into training and test sets at a ratio of 7∶3), candidate feature variables were selected from 39 related variables using the Boruta algorithm, and the multivariable Logistic regression analysis was performed with the occurrence of SAR as the dependent variable. Based on these candidate features, Logistic Regression, Extreme Gradient Boosting, Light Gradient Boosting Machine, Random Forest, and Categorical Boosting models were constructed. Model performance was evaluated using metrics including the area under the curve (AUC) of receiver operating characteristic curve and recall rate. The Shapley Additive exPlanations (SHAP) method was applied to analyze and interpret the contribution of each variable. A nomogram was constructed based on the optimal model. RESULTS A total of 38 trigger items for active monitoring of bevacizumab-related ADR were determined, comprising 17 laboratory indicators, 13 clinical manifestations, and 8 intervention measures. In total, 483 patients with positive trigger items were included, and 318 patients with bevacizumab-induced ADR were identified, including 83 SARs. The positive predictive values for the trigger items and cases were 43.57% (708/1 625) and 63.84% (318/483), respectively. Bevacizumab-induced ADR involved 7 systems/organs, with the hematological system being the most frequently involved (64.15%). The Boruta algorithm selected 7 vari ables: serum potassium, hematocrit, albumin-to-globulin ratio, prealbumin, hypertension history, age and red blood cell count. Multivariable Logistic regression showed that elevated serum potassium levels were associated with a decreased risk of bevacizumab-induced SAR (OR=0.234, P =0.002), while a history of hypertension (OR=2.642, P =0.006) and increased age (OR=1.040, P =0.025) were associated with an increased risk. The Logistic Regression model demonstrated superior performance with higher AUC, F1 score and recall rate (0.761, 0.447, 0.607), compared to other models. SHAP evaluation results indicated that variables such as serum potassium, hematocrit, and age ranked highest in importance. CONCLUSIONS Totally 38 trigger entries have been successfully identified for active screening of bevacizumab-related ADR. Elevated serum potassium levels are a protective factor against bevacizumab-induced SAR, whereas the hypertension history and increased age are risk factors. The Logistic Regression model is the optimal predictive model.

Objective To address the safety challenges arising from the rapid development of nuclear energy and technology, assess the current status of health emergency response capabilities in nuclear radiation emergencies, and promote capacity enhancement. Methods A preliminary evaluation system for health emergency response capability in nuclear radiation emergencies was developed based on a literature review. Two rounds of Delphi expert consultation (n = 20) were conducted, and the analytic hierarchy process was employed to establish judgment matrices for assigning indicator weights. Results The finalized system included six primary indicators (radiation protection capability, triage capability, decontamination and evacuation capability, medical treatment capability, radiation detection capability, and radiation dose estimation capability), along with 29 secondary indicators, such as capability for setting up emergency zones, capability for protecting personnel from internal and external contamination, on-site first aid capability, and personal dose monitoring capability. The expert response rate was 0.95, and the expert authority coefficient reached 0.80. The Kendall’s coefficient of concordance was W = 0.288 (P<0.01) for the first round of expert consultation and W = 0.308 (P<0.01) for the second round. Both rounds demonstrated high agreement among experts, and the consultation questionnaires passed reliability and validity tests. Conclusion By integrating qualitative analysis and quantitative calculation, this study developed a scientifically sound and operationally feasible evaluation system. This system will help identify gaps in health emergency response capabilities and provide scientific guidance and a decision-making basis for optimizing emergency plans and improving the level of health emergency response in nuclear radiation emergencies.

BackgroundThe violent aggressive behaviors of patients with schizophrenia usually have the characteristics of suddenness, unpredictability, high severity, and great difficulty in prevention. Early identification and accurate assessment of their risk of violent aggression have significant clinical significance. ObjectiveTo construct a predictive model for the violence risk in hospitalized patients with schizophrenia, to identify the key factors influencing the occurrence of violent behavior in these patients, so as to provide references for clinical precise quantitative assessment and early intervention. MethodsA total of 200 patients with schizophrenia who were hospitalized at Taiyuan Psychiatric Hospital from March 2022 to September 2024 and met the diagnostic criteria of the International Classification of Diseases, eleventh edition (ICD-11) were collected to form the modeling cohort. They were randomly divided into a training set (n=140) and a test set (n=60) at a ratio of 7∶3. Based on the least absolute shrinkage and selection operator (LASSO) regression algorithm, the feature variables were screened and dimension-reduced. The support vector machine (SVM) from machine learning was selected for model training and prediction. The discrimination efficacy of the model was evaluated by the area under the receiver operating characteristic (ROC) curve (AUC), accuracy, precision, sensitivity, specificity, F1 value, and Brier value. ResultsLASSO regression screening identified 16 feature variables. Pearson correlation analysis revealed a positive correlation between prior violent behavior frequency and clinical psychiatric symptom scores (r=0.580, P<0.01), a positive correlation between hospitalization compliance and current disease status (r=0.550, P=0.003), and a positive correlation between educational level and family per capita monthly income (r=0.367, P<0.01). The SVM model achieved an AUC of 0.853, accuracy of 0.800, precision of 0.810, sensitivity of 0.895, specificity of 0.636, F1 value of 0.850, and Brier value of 0.168. ConclusionThe SVM model has a relatively high level of applicability and overall predictive performance in the assessment of violent risk in schizophrenia patients, which is helpful for the early identification of violent risks in such patients.

Objective To investigate the feasibility, safety, and clinical value of endoscopic-assisted skin-sparing mastectomy combined with immediate implant-based breast reconstruction performed as day surgery for breast cancer, aiming to provide a reference for major hospitals seeking to implement a day surgery model for breast cancer treatment. Methods We retrospectively analyzed the patients who underwent endoscopic-assisted skin-sparing mastectomy combined with immediate implant-based breast reconstruction for breast cancer at West China Hospital of Sichuan University from June 2021 to December 2022, and they were divided into a day surgery group and a conventional inpatient group based on their admission model. The operative indicators, Breast-Q scores, preoperative waiting time, length of hospital stay, hospitalization costs and complications of the two groups were analyzed. Results Except for intraoperative bleeding (P=0.007), the difference between the two groups in comparison of the rest of the operative indicators was not statistically significant (all P>0.05); there was no significant difference between the two groups in preoperative and postoperative Breast-Q scores (all P>0.05); the preoperative waiting time and length of stay in hospital of the day surgery group were 4.0 (3.0, 11.0) days and 1.0 (1.0, 1.0) days, respectively, which were significantly shorter than that of the conventional inpatient group; the postoperative pain score in the day surgery group [1.0 (1.0, 1.0) points] was lower than that in the conventional inpatient group [3.0 (3.0, 3.0) points], with a statistically significant difference between the two groups (P<0.001). Additionally, the total hospitalization costs for the day surgery group and conventional inpatient group were 50 656.5 (48 145.3, 62 597.3) RMB and 53 689.3 (50 469.1, 64 826.5) RMB, respectively.The total hospitalization cost in the day surgery group was significantly lower than that in the conventional inpatient group, with a statistically significant difference between the two groups (P=0.001). There was no statistically significant difference in complications between the two groups (all P>0.05). Conclusion Endoscopic-assisted skin-sparing mastectomy combined with immediate implant-based breast reconstruction in day surgery is feasible and safe. Without increasing postoperative complications, it effectively reduces hospitalization costs and shortens medical care time, demonstrating significant clinical value.

OBJECTIVE To systematically review medication-related risk factors for falls in older adults, to provide references for ensuring medication safety among older adults. METHODS A systematic search was conducted in PubMed, Embase, Web of Science, and CNKI for relevant literature published from database inception to November 1, 2025. Relevant studies on medication-related falls in older adults, both domestic and international, were included. Drug factors influencing falls in older adults were summarized and analyzed. RESULTS A total of 22 studies were included. Four major classes of fall-risk-increasing drugs were identified: psychotropic medications [12 studies, odds ratio (OR) range 1.500-5.790], cardiovascular system drugs (5 studies, OR range 1.236-4.784), analgesics (3 studies, OR range 1.500-4.490), and hypoglycemic agents (3 studies, OR range 2.070-2.751). Additionally, anticholinergic burden (1 study, OR was 2.610) and polypharmacy (7 studies, OR range 2.902-25.897 for the use of ≥4 medications) were identified as significant risk factors for falls. CONCLUSIONS Falls in older adults are significantly associated with psychotropic medications, cardiovascular system drugs, analgesics, and hypoglycemic agents, among which psychotropic medications pose the highest risk. Anticholinergic burden and polypharmacy are also important risk factors. In clinical practice, interventions should be implemented through deprescribing and risk monitoring to effectively reduce the risk of falls in older adults.
9.Effects of Panax notoginseng saponins on gastric mucosal injury and inflammatory response in rats with chronic atrophic gastritis
China Pharmacy 2026;37(8):1021-1026
OBJECTIVE To investigate the effects and potential mechanism of Panax notoginseng saponins (PNS) on gastric mucosal injury and inflammatory response in rats with chronic atrophic gastritis (CAG) via the stem cell factor(SCF)/cellular tyrosine kinase receptor(c-kit) signaling pathway. METHODS Male SD rats were used to establish a CAG rat model through intragastric administration of N -methyl- N ′-nitro- N -nitrosoguanidine combined with an irregular diet. Successfully modeled rats were randomly divided into a model group, positive control-vitacoenzyme group (Positive group, 250 mg/kg), PNS low- and high-dose groups (PNS-L and PNS-H groups, 9, 18 mg/kg), and high-dose PNS+SCF/c-kit inhibitor group (PNS-H+ISCK03 group, 18 mg/kg+47 mg/kg), with 8 rats in each group. Additionally, 8 healthy rats were selected as a control group. After the final administration, the activities of serum gastrin (GAS), motilin (MTL) and pancreatic polypeptide (PP), as well as the levels of tumor necrosis factor-α (TNF-α), interleukin-10 (IL-10), and IL-8 in gastric mucosal tissues, were measured in each group. Pathological changes of the gastric mucosal and ultrastructure of the epithelial cells were observed, and gastric mucosal atrophy was scored. Cell apoptosis in gastric mucosal tissues and the expressions of proliferating cell nuclear antigen (PCNA), nuclear factor-κB p65 (NF-κB p65), SCF and c-kit were detected. RESULTS Compared with the control group, the model group showed significantly increased inflammatory cell infiltration in the gastric mucosal, extensive epithelial cell detachment, severe ultrastructural damage, and significantly elevated or up-regulated gastric mucosal atrophy score, TNF-α and IL-8 levels in gastric mucosal, cell apoptosis rate, and NF-κB p65 protein expression. Meanwhile, serum levels of GAS and MTL, PP activity, the level of IL-10 in gastric mucosal tissue, and protein expressions of PCNA and SCF, as well as the phosphorylation level of c-kit, were significantly decreased or down-regulated ( P <0.05). Compared with the model group, Positive, PNS-L and PNS-H groups exhibited markedly improved pathological changes in the gastric mucosal and significant amelioration of the quantitative indicators, with the PNS-H group showing significantly better improvement than the PNS-L group ( P <0.05). However, ISCK03 significantly reversed the ameliorative effects of high-dose PNS on the above indicators in rats ( P <0.05). CONCLUSIONS PNS improves gastric mucosal injury in CAG rats by reducing the inflammatory response and promoting gastric mucosal repair; these effects may be related to the activation of the SCF/c-kit signaling pathway.

A quantitative method for the analysis of the multi-component contents in Marsdenia tenacissimae was established, and the quality differences were evaluated by principal component analysis (PCA), orthogonal partial least squares-discriminant analysis (OPLS-DA), factor analysis (FA) and weighted technique for order preference by similarity to ideal solution (TOPSIS) method. The contents of chlorogenic acid, cryptochlorogenic acid, sinapic acid, tenacigenoside A, tenacissoside G, tenacissoside I, tenacissoside H, drevogenin A, betulinic acid and lupeol were determined by HPLC wavelength switching method. At the same time, the contents of alcohol-soluble extract and total ash were detected. PCA, OPLS-DA and FA methods were used to identify the origin of M. tenacissimae from different producing areas. According to the OPLS-DA model, the index weight was determined to construct the weighted TOPSIS evaluation model. The qualities of M. tenacissimae from different producing areas were analyzed by model scoring results. The contents of 12 indexes in 18 batches of M. tenacissimae varied to different degrees, and the repeatability and accuracy of the test method were satisfactory. PCA analysis divided 18 batches of M. tenacissimae into three categories. OPLS-DA identified five main potential quality markers, including tenacissoside A, tenacissoside I, lupeol, tenacissoside H and chlorogenic acid. The evaluation results of FA and weighted TOPSIS method were consistent, which showed that the quality of M. tenacissimae from Yunnan and Guizhou was better. The established multi-component quantitative analysis method is accurate and reliable, the chemometrics model has strong predictive ability, and the evaluation results of FA and weighted TOPSIS method are scientific and objective. The combination of the four methods can clearly determine the qualities of M. tenacissimae from different producing areas.
