Objective To explore the feasibility of magnetic compression technique (MCR) in the treatment of severe single mid-ureteral stricture in a rabbit model. Methods After 10 female New Zealand rabbits were selected, the distal end of the right ureter was ligated with silk thread. Two weeks after the operation, when the right ureter was dilated, the mid-ureter was ligated again with silk thread to create a severe single mid-ureteral stricture animal model. Longitudinal incisions were made at the upper and lower ends of the ligation site, and cylindrical NdFeB magnets with central holes (sub-magnets and main magnets) were placed to anastomose and recanalize the mid-ureteral stricture. The magnets were adjusted to the appropriate position to automatically align and attract each other. The longitudinal incision sites of the ureter were sutured with 6-0 Prolene thread, and the abdominal cavity was closed layer by layer. The operation time was recorded. X-ray films were taken every two days to confirm the position of the magnets and record the time of magnet detachment. Three weeks after the operation, the anastomotic specimens were obtained, and the formation of the anastomosis was evaluated with gross observation and histological staining. Results Two weeks after ligation, all experimental rabbits showed obvious dilation of the right ureter. The mid-ureteral ligation and placement of the male and female magnets were successfully completed in all 10 experimental rabbits, with an operation time of (24.00±5.15)minutes. The male and female magnets attracted each other well. X-ray examination showed that the magnets detached and entered the distal ureter (14.0±1.9) days after magnetic compression. The recanalization of the severe single mid-ureteral stricture was successfully achieved. The gross specimens and histological examination of the anastomosis showed that the anastomosis remained patent and the mucosal healing was good. All experimental rabbits survived well after the operation without serious complications. Conclusion MCT provides a new idea and novel method for the treatment of mid-ureteral stricture. This study confirmed the feasibility of this technique in treating severe single mid-ureteral stricture in a rabbit model. The operation is relatively simple and has potential for clinical application.

Objective Inflammatory myofibroblastic tumor (IMT) is a rare condition. This report summarizes the characteristics of IMT in order to strengthen clinicians' understanding of this disease. Case Presentation A 59-year-old female patient presented with intermittent right flank and abdominal pain with fever for 1 month, and a right renal mass detected 3 weeks ago. The highest body temperature during the course of the illness was 39℃. She received symptomatic antiinfective treatment at another hospital for 2 weeks, and the symptoms were alleviated. Enhanced CT of the lower abdomen strongly suggested a right renal carcinoma, with multiple small lymph nodes in the peritoneal cavity and retroperitoneum. MRI indicated a neoplastic lesion in the right kidney, with suspicion of chromophobe cell carcinoma. Laparoscopic partial right nephrectomy was performed under general anesthesia, and the procedure was successful. Postoperative pathology showed that there was significant localized infiltration of lymphocytes and formation of lymphoid follicles, and the lymph nodes showed chronic inflammation. The final diagnosis was IMT. In the follow-up of 3 months, no tumor recurrence was observed. Conclusion IMT has a high misdiagnosis rate. When imaging findings are atypical for renal cell carcinoma, IMT should be suspected. The preferred treatment is laparoscopic partial nephrectomy.

Amyotrophic lateral sclerosis (ALS) is a chronic, progressive degenerative disease affecting both upper and lower motor neurons, primarily characterized by skeletal muscle weakness and atrophy. Notably, the same muscle group may exhibit asynchronous involvement. This study aims to investigate the involvement patterns of the orbicularis oculi (OOc) and orbicularis oris (OOr) in ALS patients, compare the findings with healthy controls (HCs) and myasthenia gravis (MG) patients, and explore the characteristics and clinical significance of facial muscle involvement in ALS. Clinical and neuroelectrophysiological data were collected and analyzed in ALS patients (ALS group), HCs (HCs group) and MG patients (MG group). Clinical data included age, gender, clinical symptoms and signs, and the revised ALS Functional Rating Scale (ALSFRS-R) score. Split-face (SF) phenomenon was defined as OOc muscle strength being greater than OOr muscle strength. The negative peak amplitudes of compound motor action potential (CMAP) recorded from OOc and OOr, namely CMAPOOc and CMAPOOr, were collected for electrophysiological evaluation. Number of patients enrolled in each group: 137 in the ALS group, 42 in the HCS group, and 33 in the MG group.Of the 137 ALS patients, 74 presented clinical SF manifestation. The CMAPOOc amplitude in the ALS group was 2.00 (1.66, 2.40) mV, showing no significant difference compared with 2.20 (1.86, 2.58) mV in the HCs group ( More than half of ALS patients have SF phenomenon, and neuroelectrophysiological indicators can provide objective evidence for SF. SF is correlated with bulbar onset, severe bulbar symptoms and rapid disease progression, and can serve as a potential indicator for the differential diagnosis between ALS-BO and MG.

Objective To explore the predictive performance of machine learning models integrating clinico-pathological features and inflammatory markers for lymphovascular invasion (LVI) before gastric cancer surgery. Methods A retrospective cohort of 193 gastric cancer patients from The First Hospital of Lanzhou University (training set) and 185 patients from Zhongshan Hospital, Fudan University (validation set) was included. Preoperative clinical pathological characteristics, tumor markers, and inflammatory markers were collected to identify independent risk factors for LVI. Six machine learning models were established in the training set. Model performance was evaluated using area under the receiver operating characteristic (ROC) curve (AUC), calibration curve, decision curve analysis (DCA), and Brier scores. Shapley additive explanations (SHAP) was applied for model interpretability. Results The multivariate logistic regression showed increased tumor invasion depth (T-stage), lymph node metastases (N-stage), and the systemic immune-inflammation index (SII) were independent risk factors for gastric cancer LVI (P<0.05). Using these three indicators, 6 machine learning models were developed, all of which demonstrated favorable predictive performance, with 0.79 and 0.76 of minimum AUC values in the training set and the validation set, respectively. Among them, the light gradient boosting machine (LightGBM) model exhibited the best overall performance, achieving AUCs of 0.83 and 0.82 in the training set and the validation set, along with Brier scores of 0.163 and 0.187, respectively. Calibration and DCA curves further confirmed that the model possesses strong predictive accuracy and application value. SHAP analysis showed the feature importance in LightGBM model, identifying the N-stage as the top contributor, followed by the T-stage and the SII. Conclusion The machine learning models incorporating clinical pathological features and inflammatory indicators can effectively predict LVI status in gastric cancer, with the LightGBM model demonstrating optimal performance.

Intelligent prescription recommendation has become an important research direction in traditional Chinese medicine (TCM), offering new opportunities to support clinical decision-making and promote the modernization of TCM practice. With the rapid development of artificial intelligence (AI), a variety of computational approaches have been proposed to learn prescription patterns from clinical data and generate personalized treatment recommendations. However, despite increasing research activity, systematic and comprehensive reviews of AI-driven methods for TCM prescription recommendation remain limited. In this study, we present a comprehensive review of computational approaches for herbal prescription recommendation (HPR) in TCM. Existing methods are systematically categorized into several major paradigms, including traditional machine learning methods, topic model methods, sequential generative methods, deep learning and graph-based methods, and large language model–based frameworks. In addition to summarizing methodological developments, we also review commonly used public datasets and evaluation metrics in this field. Furthermore, representative models with publicly available implementations are experimentally evaluated on multiple benchmark datasets to provide a comparative analysis of their performance on the HPR task. Finally, we discuss the key challenges that hinder the practical deployment of intelligent prescription recommendation systems, including data heterogeneity, limited interpretability, and insufficient integration of TCM domain knowledge. Future research directions are outlined to facilitate the development of more reliable, interpretable, and clinically applicable AI-assisted HPR systems for TCM.

OBJECTIVE To investigate the stability and compatibility of butorphanol, nicardipine, urapidil, and tirofiban. METHODS A micro-infusion pump was used to simulate the infusion process. Samples were collected in real time from the needle tip at 0, 2, 4, 6, and 8 h after mixing of the four drugs. The appearance, pH, and number of insoluble particles were examined. The contents of butorphanol, nicardipine, urapidil, and tirofiban were determined using the ultra-high-performance liquid chromatography method. RESULTS Within 8 hours, all mixed solutions remained clear and transparent, with no visible turbidity, precipitation, color change, or gas generation. The pH fluctuation ranged from 0.02 to 0.09, both within 0.1 pH units. The number of insoluble particles ≥10 μm in size in each compatibility solution was ≤9, and the number of insoluble particles ≥25 μm was ≤2, meeting the requirements of the 2025 edition of the Chinese Pharmacopoeia (Volume Ⅳ). The relative percentage contents of butorphanol, nicardipine, urapidil, and tirofiban at 8 hours after compatibility mixing ranged from 92.38% to 113.40%. CONCLUSIONS Within 8 hours under simulated clinical micro-infusion pump infusion conditions, the stability and compatibility of the mixed solution containing butorphanol, nicardipine, urapidil, and tirofiban were satisfactory.

It is considered that lean metabolic associated fatty liver disease (MAFLD) is characte-rized by a state of "lean body but fatty liver". From the perspective of the pathomechanism evolution of "spleen failing to disperse essence, while kidney failing to transform qi", the disease is systematically treated under the principle that spleen and kidney deficiency as the root and liver constraint with phlegm stasis as the branch. Spleen deficiency with impaired transformation and transportation leads to failure in the distribution of refined substances, initiating lipid turbidity accumulation and obstruction. Kidney dysfunction in qi transformation results in insufficient essence and blood, forming the root of bodily malnourishment. Over time, this further gives rise to liver constraint and loss of dispersing function, disorder in the movement of essential substances, and congealing of phlegm and stasis within hepatic collaterals. The dysfunction of three organs including spleen, kidney and liver constitutes the pathological basis of metabolic disturbances involving qi, blood, body fluids and essence. Treatment should follow the principle of "nourishing the healthy qi leads to spontaneous resolution of pathogenic accumulation", with three approaches. First, fortifying the spleen and eliminating dampness, using Sini Powder (四逆散) and Erchen Pingwei Powder (二陈平胃散) to restore the transport and transformation function of the middle jiao (焦), thereby guiding essential substances back to their proper physiological pathways. Second, tonifying the kidney and resolving turbidity, using Jinkui Shenqi Pill (金匮肾气丸) and Effective Integration Decoction (一贯煎) to replenish the lower jiao, promoting the restoration of essence and the transformation of turbid pathogen. Third, soothing the liver and resolving stasis, using Liujunzi Decoction (六君子汤) and Xiaozhi Qinggan Decoction (消脂清肝汤) to vent qi and blood stagnation, thereby interrupting disease progression. Together, these three methods reinforce healthy qi while eliminating pathogen, facilitating the restoration of proper essence transformation and the resolution of lipid turbidity.

ObjectiveThis paper aims to investigate the role of NDC80 kinetochore complex component (NUF2) and magnesium homeostasis in ovarian cancer cell apoptosis, as well as the regulatory mechanism of gypenoside L (Gyp-L) on NUF2 and magnesium homeostasis. MethodsOvarian cancer OVCAR3 cells were divided into a blank control group, a low-concentration Gyp-L group (50 µmol·L-1), a high-concentration Gyp-L group (100 µmol·L-1), and a cisplatin (15 µmol·L-1) group. The migration, proliferation, and apoptosis capabilities of OVCAR3 cells were evaluated through cell scratch assays, clonal experiments, and terminal-deoxynucleotidyl transferase-mediated dUTP-biotin nick end labeling assay (TUNEL) staining. Differentially expressed genes of ovarian cancer were screened by using the Gene Expression Omnibus (GEO) database. The interaction relationships of differentially expressed genes and proteins were analyzed via the Search Tool for Recurring Instances of Neighbouring Genes (STRING) database. The prognostic survival analysis was performed by using the Tumor Immune Estimation Resource (TIMER) database, and the differential expression levels of genes were validated with the Gene Expression Profiling Interactive Analysis (GEPIA) database. The mRNA expression levels of NUF2, magnesium homeostasis-related indicators, such as magnesium transporter 1 (MAGT1), non-imprinted in Prader-Willi/Angelman syndrome 1 (NIPA1), NIPA-like domain containing 1 (NIPAL1), as well as apoptosis-related indicators B cell lymphoma-2 (Bcl-2) and Bcl-2-associated X protein (Bax) in OVCAR3 cells, were detected by real-time quantitative polymerase chain reaction (Real-time PCR). The protein expression levels of NUF2, MAGT1, NIPA1, NIPAL1, Bcl-2, and Bax in OVCAR3 cells were quantitatively analyzed by ProteinSimple WES. A model of overexpression of NUF2 was constructed, and Gyp-L intervention was performed. The molecular mechanism by which Gyp-L induces ovarian cancer cell apoptosis by regulating NUF2 and influencing magnesium homeostasis was quantitatively analyzed and detected through cell cloning, TUNEL staining, Real-time PCR, and ProteinSimple WES. Finally, the Mg2+ content and protein synthesis efficiency were detected by immunofluorescence. ResultsGyp-L significantly inhibited the migration and proliferation capabilities of OVCAR3 cells and promoted their apoptosis (P<0.05). Overexpression of NUF2 markedly increased the expression levels of MAGT1, NIPA1, NIPAL1, and Bcl-2, while reducing the expression level of Bax (P<0.05). It also significantly elevated intracellular Mg2+ content and protein synthesis efficiency and simultaneously inhibited apoptosis (P<0.05). Gyp-L could reverse the magnesium homeostasis imbalance and apoptosis inhibition caused by the overexpression of NUF2, downregulating the expression levels of NUF2, MAGT1, NIPA1, NIPAL1, and Bcl-2 (P<0.05), while upregulating the expression level of Bax (P<0.05). ConclusionGyp-L can inhibit the occurrence of ovarian cancer, and its mechanism may involve inhibiting the expression of NUF2 to maintain magnesium homeostasis and inducing apoptosis of ovarian cancer cells.

ObjectiveThis paper aims to observe the syndrome improvement and negative antigen conversion rate of Qingxuan Daozhi formula in the treatment of influenza in children (heat accumulation in the lung and stomach syndrome). MethodsThrough a multi-center randomized controlled methodology design,confirmed influenza cases were collected from October 2022 to April 2023 in the pediatrics department of eight hospitals,such as Dongfang Hospital of Beijing University of Chinese Medicine. A total of 180 children with influenza and heat accumulation in the lung and stomach syndrome conforming to the standard were recruited through the clinic. The sick children meeting the inclusion criteria were randomly divided into groups by a block-randomized method. The children in the experimental group were treated with Qingxuan Daozhi formula for five days,and those in the control group were treated with Oseltamivir Phosphate Granules for five days. The primary efficacy indicator was the negative conversion rate of influenza antigen detection. Secondary efficacy indicators were the Canadian acute respiratory illness and flu scale (CARIFS) and the incidence of complications,severe cases, and critical cases. Follow-up observation was conducted on the day of enrollment,48 hours after medication,72 hours after medication, and (6+1) d after medication. ResultsOne hundred and eighty participants were randomly assigned to the experimental group (90 cases) or the control group (90 cases). All participants were followed up during the study. Comparison of influenza antigen detection results in the primary efficacy indicators showed that the average time of negative influenza antigen conversion in the experimental group was (5.29±1.25) d,and that in the control group was (5.40±1.68) d,without a statistically significant difference. After five days of intervention,52 cases in the experimental group and 51 cases in the control group converted to negative,without a statistically significant difference. CARIFS score results in the secondary efficacy indicators showed that during 72 hours after intervention,there were statistically significant differences between the experimental group and the control group in three dimensions, including headache,muscle soreness, and the need for extra care (P<0.05). On the (6+1) days after the intervention,the differences in both the experimental group and the control group were statistically significant in 10 dimensions, including sore throat,bad sleep,uncomfortable feeling,poor spirit and fatigue,crying more than usual,the need for extra care,symptom,function,influence on parents,and total score (P<0.05). The comparison results within the group in the dimensional scores of symptom, function, and influence on parents,as well as the CARIFS total score showed that with the delay of follow-up time,scores of both groups decreased significantly,with a statistically significant difference (P<0.01). Inter-group comparison results showed that the mean score of the experimental group was higher than that of the control group at the time of enrollment. With the progress of intervention,the score of the experimental group was significantly decreased compared with that of the control group. At the end of follow-up,the mean score of the experimental group was lower than that of the control group,with no statistically significant difference. In terms of the incidence of complications,severe cases, and critical cases, there were no complications,severe cases, and critical cases in the two groups,without a statistically significant difference. ConclusionThe symptom improvement effect and negative antigen conversion rate of Qingxuan Daozhi formula in the treatment of influenza in children (heat accumulation in the lung and stomach syndrome) are not inferior to Oseltamivir Phosphate granules, and children's acceptance is better. It can be more widely used in clinical treatment of influenza in children (heat accumulation in the lung and stomach syndrome).
