Objective To establish quality evaluation method of Andrographis paniculata standard decoction by UPLC. Methods 21 batches of Andrographis paniculata standard decoctions were prepared according to the standardization method of TCM decoction pieces. The UPLC characteristic chromatograms analysis method was established. With andrographolide as a reference, quantitative analysis of multi-components by single marker (QAMS) was established for new neoandrographolide, 14 deoxyandrographolide and dehydrated andrographolide. The results were compared with the external standard method (ESM) to determine the accuracy of the method. Results Similarity Evaluation System for Chromatographic Fingerprint of TCM (2012 edition) was used to analyze and compare the characteristic chromatograms, and seven common peaks were determined and five were identified including luteolin-7-O-β-D-glucuronide, andrographolide, neoandrographolide, 14-deoxyandrographolide and dehydroandrographolide. The RSDs of content results of each component by QAMS and ESM were all within 3%. Conclusion The determination method was reliable and accurate, which could be used to reflect the intrinsic quality of Andrographis paniculata standard decoction comprehensively and provide the basis for the quality evaluation of Andrographis paniculata formula granules and other preparations.

To analyze the application value of artificial intelligence (AI)-based classification in the categorization of medical adverse events. Medical adverse events reported to the Adverse Event Reporting System of Peking Union Medical College Hospital from September 1, 2023, to August 31, 2024, were retrospectively collected as the study subjects. After de-identification of adverse events meeting the inclusion criteria, conventional manual classification and AI-based classification using a large language model (DeepSeek-R1 Full-Context Internet Edition) were performed. The time required for classification using both methods was recorded, and the consistency and discrepancies between the two methods were compared. Using manual classification as the gold standard, the accuracy of AI-based classification was comprehensively evaluated. A total of 273 medical adverse events were analyzed. Manual classification took 38 838 seconds in total, with an average of 14.22 seconds per event. AI-based classification took 600 seconds in total, with an average of 2.19 seconds per event. The two methods showed consistent classification in 202 events and inconsistent classification in 71 events, yielding an overall agreement rate of 73.99% and a Kappa coefficient of 0.646 (95% CI: 0.575-0.717), with a standard error of 0.0362. Using manual classification as the gold standard, AI-based classification achieved accuracy ranging from 80% to 100%, precision from 30% to 100%, recall from 40% to 100%, F1 scores from 0.46 to 0.79, and specificity from 46% to 98%. Notably, AI-based classification demonstrated balanced and overall excellent performance in the categorization of device-related and drug-related adverse events. The DeepSeek large language model can assist in improving the efficiency of medical adverse event classification, showing promising application potential, particularly in the categorization of device-related and drug-related adverse events.

Objective:To explore the clinical, imaging, and pathological features of glottic squamous cell carcinoma of the larynx and their relationship with prognosis. Methods:A retrospective analysis was conducted on the clinical, imaging, and pathological data of 130 patients with glottic squamous cell carcinoma of the larynx who were treated at the First People's Hospital of Yinchuan and the General Hospital of Ningxia Medical University from January 2018 to March 2023. Imaging examinations (CT and MRI) were used to evaluate the lesion boundary clarity, density, enhancement nature, and enhancement degree. Postoperative pathological examination was used to determine the pathological nature, immunohistochemistry, etc. Statistical methods such as χ² test, Spearman correlation analysis, multivariate logistic regression analysis, and Kaplan-Meier method were used to analyze the data. Results:Among the 130 patients, 127 were male and 3 were female, with an average age of (61.92±9.595) years. There was a correlation between clinical, imaging, and pathological features. Multivariate analysis showed that heterogeneous MRI density (OR=12.414;P=0.019) and squamous cell carcinoma as a subtype were correlated. The initial symptom of non-hoarseness (HR=6.045;P=0.010) and unclear MRI boundary (HR=12.559; P=0.029) were independent risk factors for poor prognosis in patients with glottic squamous cell carcinoma of the larynx. Conclusion:There is a correlation between the clinical, imaging, and pathological features of patients with glottic squamous cell carcinoma of the larynx, and they can affect prognosis. The initial symptom of non-hoarseness and unclear MRI boundary of the tumor are independent risk factors for poor prognosis.

To analyze the disease group structure and its trends in key departments of large public hospitals using diagnosis related group (DRG) data, explore the key points of intervention and optimization of disease groups in departments, and further promote the rational allocation of department resources. We retrospectively collected DRG data from two surgical departments in a large public hospital in Beijing from 2017 to 2023. When the case mix index (CMI) of the two surgical departments declined, interventions such as performance appraisal, department education, and hospital publicity were promptly adopted. The changesin CMI values were observed and the trends in disease group weights, time consumption index, cost consumption index, and mortality rate in low-risk groups were analyzed. After the interventions, in surgical department Ⅰ, the proportion of patients with lower-weight diseases, such as major thyroid surgery (KD1), significantly decreased, while that of patients with higher-weight diseases, such as colorectal malignancy surgery (GB2) and pancreatic malignancy surgery (HB1), significantly increased. In surgical department Ⅱ, the proportion of patients with lower-weight diseases, such as chemotherapy (RE1), decreased markedly, while that of patients with higher-weight diseases, including major surgery for malignancy of kidney, ureter, and bladder (LA1), adrenal gland surgery (KC1), surgery for kidney/ureter/bladder except for major malignancy surgery (LB1), and male genital organ malignancy surgery (MA1), increased significantly. Both surgical departments achieved the goal of increasing their CMI values. In terms of efficiency, cost, and quality indicators, the time consumption index and cost consumption index of the two surgical departments were significantly lower than 1, and the mortality rate in low-risk groups was 0. Based on actual conditions and development goals, large public hospitals can achieve improvements in CMI values and optimization of disease group structures through reasonable interventions, thereby enhancing medical efficiency and rational utilization of resources.

Objective:To investigate the clinical features and therapeutic efficacy of patients with hereditary leiomyomatosis and renal cell carcinoma(RCC) syndrome-associated RCC (HLRCC-RCC) in China.Methods:The clinical data of 119 HLRCC-RCC patients with fumarate hydratase (FH) germline mutation confirmed by genetic diagnosis from 15 medical centers nationwide from January 2008 to December 2021 were retrospectively analyzed. Among them, 73 were male and 46 were female. The median age was 38(13, 74) years. The median tumor diameter was 6.5 (1.0, 20.5) cm. There were 38 cases (31.9%) in stage Ⅰ-Ⅱand 81 cases (68.1%) in stage Ⅲ-Ⅳ. In this group, only 11 of 119 HLRCC-RCC patients presented with skin smooth muscle tumors, and 44 of 46 female HLRCC-RCC patients had a history of uterine fibroids. The pathological characteristics, treatment methods, prognosis and survival of the patients were summarized.Results:A total of 86 patients underwent surgical treatment, including 70 cases of radical nephrectomy, 5 cases of partial nephrectomy, and 11 cases of reductive nephrectomy. The other 33 patients with newly diagnosed metastasis underwent renal puncture biopsy. The results of genetic testing showed that 94 patients had FH gene point mutation, 18 had FH gene insertion/deletion mutation, 4 had FH gene splicing mutation, 2 had FH gene large fragment deletion and 1 had FH gene copy number mutation. Immunohistochemical staining showed strong 2-succinocysteine (2-SC) positive and FH negative in 113 patients. A total of 102 patients received systematic treatment, including 44 newly diagnosed patients with metastasis and 58 patients with postoperative metastasis. Among them, 33 patients were treated with tyrosine kinase inhibitor (TKI) combined with immune checkpoint inhibitor (ICI), 8 patients were treated with bevacizumab combined with erlotinib, and 61 patients were treated with TKI monotherapy. Survival analysis showed that the median progression-free survival (PFS) of TKI combined with ICI was 18 (5, 38) months, and the median overall survival (OS) was not reached. The median PFS and OS were 12 (5, 14) months and 30 (10, 32) months in the bevacizumab combined with erlotinib treatment group, respectively. The median PFS and OS were 10 (3, 64) months and 44 (10, 74) months in the TKI monotherapy group, respectively. PFS ( P=0.009) and OS ( P=0.006) in TKI combined with ICI group were better than those in bevacizumab combined with erlotinib group. The median PFS ( P=0.003) and median OS ( P=0.028) in TKI combined with ICI group were better than those in TKI monotherapy group. Conclusions:HLRCC-RCC is rare but has a high degree of malignancy, poor prognosis and familial genetic characteristics. Immunohistochemical staining with strong positive 2-SC and negative FH can provide an important basis for clinical diagnosis. Genetic detection of FH gene germ line mutation can confirm the diagnosis. The preliminary study results confirmed that TKI combined with ICI had a good clinical effect, but it needs to be confirmed by the results of a large sample multi-center randomized controlled clinical study.

Objective:To analyze the clinical characteristics and treatment of patients with renovascular hypertension (RVH) caused by renal arterial fibromuscular dysplasia (FMD).Methods:Clinical data and treatment result of 38 patients with renal arterial FMD and RVH admitted to our hospital from Jan 2014 to Dec 2020 were reviewed.Results:A total of 38 patients were enrolled in this study. Renal artery CTA showed that 40 renal arteries were involved, among these 6 branches had multifocal stenosis, and 34 branches had focal stenosis. Thity-three patients received surgical treatment, of which 32 patients underwent percutaneous transluminal renal angioplasty (PTRA), and 1 patient with renal aneurysm underwent renal artery stent implantation combined with aneurysm coil embolization. Postoperative blood pressure was significantly lower than that before the operation [(129.79±17.63) mmHg vs. (178.52±28.63) mmHg, t=-11.42, P<0.001]. The mean follow-up time was 35.5 months. Renal artery restenosis occurred in 4 patients and underwent reintervention. Conclusion:For patients with renal arterial FMD and RVH, PTRA is safe and effective, especially for patients with focal lesions, with fair short and mid-term prognosis.

BACKGROUND:
Hypertrophic cardiomyopathy (HCM) is an underdiagnosed genetic heart disease worldwide. The management and prognosis of obstructive HCM (HOCM) and non-obstructive HCM (HNCM) are quite different, but it also remains challenging to discriminate these two subtypes. HCM is characterized by dysmetabolism, and myocardial amino acid (AA) metabolism is robustly changed. The present study aimed to delineate plasma AA and derivatives profiles, and identify potential biomarkers for HCM.
METHODS:
Plasma samples from 166 participants, including 57 cases of HOCM, 52 cases of HNCM, and 57 normal controls (NCs), who first visited the International Cooperation Center for HCM, Xijing Hospital between December 2019 and September 2020, were collected and analyzed by high-performance liquid chromatography-mass spectrometry based on targeted AA metabolomics. Three separate classification algorithms, including random forest, support vector machine, and logistic regression, were applied for the identification of specific AA and derivatives compositions for HCM and the development of screening models to discriminate HCM from NC as well as HOCM from HNCM.
RESULTS:
The univariate analysis showed that the serine, glycine, proline, citrulline, glutamine, cystine, creatinine, cysteine, choline, and aminoadipic acid levels in the HCM group were significantly different from those in the NC group. Four AAs and derivatives (Panel A; proline, glycine, cysteine, and choline) were screened out by multiple feature selection algorithms for discriminating HCM patients from NCs. The receiver operating characteristic (ROC) analysis in Panel A yielded an area under the ROC curve (AUC) of 0.83 (0.75-0.91) in the training set and 0.79 (0.65-0.94) in the validation set. Moreover, among 10 AAs and derivatives (arginine, phenylalanine, tyrosine, proline, alanine, asparagine, creatine, tryptophan, ornithine, and choline) with statistical significance between HOCM and HNCM, 3 AAs (Panel B; arginine, proline, and ornithine) were selected to differentiate the two subgroups. The AUC values in the training and validation sets for Panel B were 0.83 (0.74-0.93) and 0.82 (0.66-0.98), respectively.
CONCLUSIONS
The plasma AA and derivatives profiles were distinct between the HCM and NC groups. Based on the differential profiles, the two established screening models have potential value in assisting HCM screening and identifying whether it is obstructive.

Objective:To analyze the hepatic hemodynamics changes after partial splenic embolization in patients with cirrhosis and hypersplenism.Methods:A total of 26 patients with cirrhosis and hypersplenism who underwent partial splenic embolization in the General Hospital of Ningxia Medical University from April 2018 to June 2019 were included in this study. The clinical data was retrospectively studied. The study objects consisted of 19 males and 7 females with an average of 55 years. Whole-liver perfusion enhanced CT imaging scan was performed for all patients. Changes in laboratory indexes and the blood perfusion of the liver sections including hepatic arterial perfusion, portal venous perfusion, total liver perfusion and hepatic arterial perfusion indexes before PSE and postoperative 1 month were compared.Results:The postoperative leukocyte and platelet counts increased, and the prothrombin time decreased in the 26 patient, and the differences were significant ( P<0.05). The hepatic arterial perfusion of the left lateral section, left medial section, right anterior section and right posterior section increased in postoperative 1 month, from 10.0 (7.0, 13.5) ml·min -1·(100 ml) -1, 9.3 (5.4, 12.8) ml·min -1·(100 ml) -1, 8.0 (6.0, 11.2) ml·min -1·(100 ml) -1, 10.7 (7.1, 13.8) ml·min -1·(100 ml) -1 to 7.7 (4.2, 11.0) ml·min -1·(100 ml) -1, 6.9 (2.6, 10.2) ml·min -1·(100 ml) -1, 7.1 (4.1, 8.7) ml·min -1·(100 ml) -1, 5.9 (4.4, 8.5) ml·min -1·(100 ml) -1, respectively. The differences were all significantly different ( P<0.05). There were no significant difference in portal venous perfusion and total liver perfusion before and after operation ( P>0.05). The hepatic arterial perfusion index of left lateral section, right anterior section and right posterior section increased after operation ( P<0.05). Conclusion:For patients with cirrhosis and hypersplenism who underwent partial splenic embolization, the state of hypersplenism was relieved, the hepatic arterial blood flow increased, and the liver function improved.
