[Objective] To compare the diagnostic accuracy of three imaging modalities, inlducing CT urography (CTU), contrast-enhanced MRI (CE-MRI), and contrast-enhanced ultrasound (CEUS) in the qualitative diagnosis of renal space-occupying lesions. [Methods] A retrospective analysis was performed on 542 patients with renal lesions confirmed by surgical pathology in our hospital during Jan.2019 and May 2024.The diagnostic results of CTU, CE-MRI and CEUS were compared and analyzed based on the patients' clinical and pathological data. [Results] The diagnostic accuracy rate of CTU, CE-MRI and CEUS were 84.50%, 83.14% and 86.14%, respectively.For the 161 patients who underwent all three examinations, CEUS was significantly more accurate than CTU (84.16% vs. 77.02%, P=0.018), while there was no significant difference between CTU or CEUS and CE-MRI (79.81%) (P>0.05). Further analysis found that for lesions ≤4 cm, the accuracy of the three examinations was as follows: CEUS=CTU 79.55%, CE-MRI 76.14%, with no significant difference (P>0.05). However, for lesions >4 cm, CEUS ranked the first, followed by CE-MRI and CTU (89.73% vs. 84.25% vs. 73.97%), and CEUS and CE-MRI were better than CTU (P<0.05). Additionally, for the diagnosis of clear cell renal carcinoma and benign renal space-occupying lesions, there was no statistically significant difference among the three imaging modalities (P>0.05), while for the qualitative diagnosis of non-clear cell renal carcinoma, CEUS ranked the first, followed by CE-MRI and CTU (83.87% vs. 74.19% vs. 56.45%), and CE-MRI and CEUS were better than CTU (P<0.05). [Conclusion] All of them have important diagnostic value, and the appropriate selection should be based on patients' specifc conditions.CEUS and CE-MRI are more accurate in the qualitative diagnosis of renal space-occupying lesions than CTU, especially for large lesions and non-clear cell carcinoma.

[Objective] To analyze the prognostic value of prostate cancer (PCa) pyroptosis-related genes (PRGs) using gene expression databases and to explore the regulatory mechanism of nucleotidebinding oligomerization domain-like receptor containing pyrin domain 1 (NLRP1) in the pyroptosis of PCa cells. [Methods] Fragments per kilobase of exon model per million reads mapped (FPKM) data and clinical information from PCa and adjacent tissues from The Cancer Genome Atlas (TCGA) and Gene Expression Omnibus (GEO) were obtained. Differentially expressed PRGs between PCa and adjacent tissues, classified subtypes and plotted survival curves were analyzed. Univariate Cox regression analysis, least absolute shrinkage and selection operator (LASSO) regression analysis were conducted to screen prognosis-related PRGs, risk scores were calculated, and a prognostic risk model was constructed and validated. Patients were divided into high and low risk groups based on the median risk scores from the training and validation sets, and gene ontology (GO) enrichment and kyoto encyclopedia of genes and genomes (KEGG) analysis were conducted on differentially expressed PRGs. Quantitative real-time polymerase chain reaction (qRT-PCR) was used to detect the expression level of NLRP1 in PCa cell lines, and pyroptosis was induced in DU145 and LNCaP cells while morphological changes were observed. Western blot (WB) was performed to detect the expression of pyroptosis-related molecules. [Results] A total of 6 prognostic-related PRGs were obtained, including CHMP4C, CYCS, GPX4, GSDMB, NLRP1, and PLCG1. The risk score was positively correlated with the risk of recurrence but negatively correlated with the progression-free survival (P<0.001). The area under the receiver operating characteristic curves (AUCs) for the training set at 1, 3, and 5 years were 0.769 (95%CI: 0.652-0.878), 0.804 (95%CI: 0.736-0.882), and 0.772 (95%CI: 0.631-0.905), respectively, while those for the validation set were 0.731 (95%CI: 0.647-0.826), 0.753 (95%CI: 0.674-0.818), and 0.763 (95%CI: 0.626-0.849), respectively. Differences in expression levels of the 6 PRGs were observed between the high and low risk groups in both the training and validation sets (P<0.05). Cox regression analysis showed that T stage, prostate specific antigen (PSA), Gleason grade, and risk score were independent predictors of PCa prognosis (P<0.05). Differences in risk scores were observed among patients of different ages, T stages, and Gleason grades (P<0.05). NLRP1 was found to be lowly expressed in PCa cell lines and was involved in the regulation of pyroptosis in DU145 and LNCaP cells. [Conclusion] The prognostic risk model constructed based on PRGs has a certain predictability for the prognosis of PCa patients, and NLRP1 may be involved in the regulation of pyroptosis in PCa cells.

Depression is a common psychiatric disorder characterized by persistent low mood or mental disorders. Current treatments primarily focus on regulating neurotransmitter levels, but their effectiveness is limited. The mechanisms underlying its onset are complex, and there is no unified consensus. Abnormal signaling pathway transmission plays a crucial role in the development of depression, involving multiple pathways, including Toll-like receptor 4/nucleotide-binding oligomerization domain-like receptor protein 3 (TLR4/NLRP3), nuclear factor-κB (NF-κB), Janus kinase/signal transducer and activator of transcription (JAK/STAT), mitogen-activated protein kinase/extracellular signal-regulated kinase (MAPK/ERK), brain-derived neurotrophic factor/tyrosine kinase receptor B (BDNF/TrkB), cyclic AMP/protein kinase A/cAMP response element-binding protein (cAMP/PKA/CREB), and others. Traditional Chinese medicine(TCM) is based on a holistic approach and the principle of treatment based on the differentiation of syndromes, regulating the balance of multiple systems and organ functions from a macroscopic perspective. This approach has shown unique advantages in the treatment of depression. TCM attributes the onset of depression to dysfunction of the organ systems, involving liver Qi stagnation, heart spirit deficiency, kidney essence depletion, and spleen dysfunction. TCM compound treatments focus on soothing the liver, strengthening the spleen, calming the heart, and replenishing essence, with formulas such as Xiaoyaosan, Zishui Qinggan Yin, and Chahu Jia Guizhi Longgu Muli Tang. The active components of Chinese herbs mainly aim to tonify and regulate Qi, such as salidroside, ginsenoside Rb1, astragaloside, and muscone. External TCM treatments, primarily acupuncture, aim to open the orifices and invigorate the spirit. Acupoints such as Baihui, Shenting, and Yintang are commonly used. Additionally, massage and moxibustion therapy can intervene in depression by regulating signaling pathways. This article reviews the core role of signaling pathways in the development of depression and the mechanism of TCM regulation of signaling pathways to intervene in depression, aiming to discover new therapeutic approaches that can improve the symptoms of depressed patients.

OBJECTIVE To provide a reference for the pharmaceutical care of a patient with type 2 diabetes mellitus (T2DM) and limb-girdle muscular dystrophy (LGMD) who developed euglycemic diabetic ketoacidosis (euDKA) after taking empagliflozin. METHODS Clinical pharmacists provided pharmaceutical care for a patient with T2DM and LGMD who developed euDKA after taking empagliflozin. According to the patient’s recent use of medications and his conditions, clinical pharmacists assessed the correlation between euDKA and empagliflozin as “very likely”. As to euDKA, clinical pharmacists suggested discontinuing empagliflozin and metformin, and giving intravenous infusion of 10% Glucose injection instead of 5% Glucose injection for fluid resuscitation. Clinical pharmacists monitored the patient’s laboratory indicators such as arterial blood gas analysis, blood/urine ketones and electrolytes. They assisted physicians to decide when to stop intravenous supplements of liquid and insulin. Clinical pharmacists also assisted physicians to adjust the antidiabetic drugs and educated the patient to avoid empagliflozin or other sodium- glucose linked transporter 2 inhibitors (SGLT2i). RESULTS Physicians adopted the suggestions of clinical pharmacists. After treatment, the patient’s condition improved, and he was allowed to be discharged with medication. CONCLUSIONS euDKA is a relatively rare and serious adverse reaction associated with SGLT2i, and the patients with LGMD are susceptible to euDKA. Clinical pharmacists assist physicians in developing personalized medication plans by evaluating the association between euDKA and empagliflozin, adjusting medication regimens,conducting pharmaceutical monitoring,and other pharmaceutical services. Meanwhile, they provide medication education to patients to ensure their medication safety.

ObjectiveTo explore the possible mechanism of action of Bushen Huoxue Granules (补肾活血颗粒, BHG) in the treatment of Parkinson's disease (PD) through the Nrf2/NLRP3 inflammasome axis. MethodsA total of 84 male C57/BL 6 mice were randomly divided into blank group, model group, Madopar group, dimethyl fumarate group, and low-, medium, and high-dose BHG group, with 12 mice in each group. Except for the blank group, all groups were induced into PD models by intraperitoneal injection of 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP) at a concentration of 30 mg/ml for 7 consecutive days. The blank group received an equal volume of saline. After model establishment, the low-, medium, and high-dose BHG groups were treated with 1.5, 3, and 6 g/(kg·d) of the BHG by gavage, respectively. The Madopar group was given 0.113 g/(kg·d) of Madopar tablets by gavage, and the dimethyl fumarate group was given 50 mg/(kg·d) of dimethyl fumarate solution. The blank group and the model group were given 10 ml/(kg·d) of distilled water by gavage. Gavage was administered once daily for 14 days. Behavioral changes were evaluated using the open field test (total distance, central area distance, and average speed), rotarod test (time on the rod), and climbing pole test (climbing time). Serum levels of interleukin-1β (IL-1β), interleukin-18 (IL-18), and myeloperoxidase (MPO) were measured by ELISA. Immunohistochemistry was used to detect tyrosine hydroxylase (TH) expression in the brain substantia nigra. Immunofluorescence was used to detect α-synuclein (α-syn) expression. Western Blot was used to detect Nrf2, NLRP3, Caspase-1, and α-syn protein levels in the brain substantia nigra. RT-PCR was used to detect mRNA expression levels of Nrf2, NLRP3, and Caspase-1 in the brain substantia nigra. ResultsCompared with the blank group, the model group showed decreased total distance, central area distance, and average speed, reduced time on the rotarod, prolonged climbing time, reduced TH expression, increased α-syn expression, decreased Nrf2 protein and mRNA expression, increased NLRP3 and Caspase-1 protein and mRNA expression, and elevated serum IL-1β, IL-18, and MPO levels (P<0.05). Compared with the model group, all drug interventions significantly improved the above indicators (P<0.05). There was no significant differences in all indicators between the high-dose BHG group and the Madopar group (P>0.05). Compared with the dimethyl fumarate group, the medium and high-dose BHG groups showed increased Nrf2 mRNA expression in the brain substantia nigra (P<0.05). Compared with the high-dose BHG group, the low-dose group showed decreased total distance, central area distance, and average speed, reduced serum IL-18 levels, decreased α-syn, Nrf2, NLRP3, and Caspase-1 protein levels, and lower Nrf2 mRNA expression (P<0.05). ConclusionThe mechanism by which BHG treat PD may involve activating the Nrf2/NLRP3 inflammasome axis in the brain substantia nigra, thereby reducing neuroinflammation and α-syn aggregation. The high-dose group showed the best effects.

ObjectiveTo observe the inhibitory effect of the Weiliuan mixture (WLAHJ) on the subcutaneous xenograft tumor of MKN-74 gastric cancer cells, and explore the potential anti-gastric cancer mechanism of WLAHJ by using transcriptomic sequencing technology to reveal related genes and pathways. Methods30 Balb/c nude mice were randomly divided into model, low-, medium-, and high-dose(15,30,45 g·kg-1) WLAHJ and 5-FU (0.025 g·kg-1) groups to build a subcutaneous xenograft tumor model with MKN-74 human gastric cancer cells. After modeling,each group was continuously treated with the corresponding drugs for 28 days. During the treatment period, the body weight and tumor size of the mice were observed and recorded every 2 days. At the end of the treatment, the mice were sacrificed, and required samples were collected to calculate the tumor inhibition rate of WLAHJ on the subcutaneous xenograft tumor. High-throughput transcriptomic sequencing (RNA-seq) technology was used to analyze the differentially expressed genes in the subcutaneous tumor tissues of the model group and the medium-dose WLAHJ group, thus exploring the potential mechanism of WLAHJ in gastric cancer intervention. Immunofluorescence experiments were conducted to detect the protein expression levels of glutathione peroxidase 4 (GPX4), solute carrier family 7 member 11 (SLC7A11), transferrin receptor protein-1 (TFR-1), and acyl-CoA synthetase long-chain family member 4 (ACSL4) in subcutaneous xenograft tumors of each group. Cell counting kit-8(CCK-8) and colony formation assays were used to detect the viability and anti-proliferative ability of human gastric cancer AGS and MKN-74 cells at different concentrations of WLAHJ. Kits were used to detect the levels of Fe2+, reactive oxygen species (ROS), malondialdehyde (MDA), and superoxide dismutase (SOD) activity in cells. Western blot was used to detect the expression levels of GPX4, SLC7A11, TRF-1, ACSL4, spermidine/spermine N1-acetyltransferase 1 (SAT1), arachidonic acid 15-lipoxygenase (ALOX15), and key proteins in the phosphatidylinositol 3-kinase (PI3K)/protein kinase B (Akt)/mammalian target of rapamycin (mTOR) signaling pathway. ResultsThe mechanism of WLAHJ in gastric cancer intervention may be related to ferroptosis and the PI3K/Akt /mTOR signaling pathway. The growth of subcutaneous xenograft tumors in nude mice of the WLAHJ and 5-FU groups(P<0.05,P<0.01), GPX4, and SLC7A11 dropped significantly(P<0.01), while TFR-1, ACSL4, SAT1, and ALOX15(P<0.05,P<0.01)increased significantly compared with those in the model group. The levels of ROS, Fe2+, and MDA increased in the WLAHJ and 5-FU groups and the proliferation of gastric cancer cells, SOD activity, the ratios of phosphorybation (p)-mTOR/mTOR, p-PI3K/PI3K, and p-Akt/Akt protein expressions(P<0.05,P<0.01)decreased compared with those in the blank group. ConclusionThe mechanism of WLAHJ in treating gastric cancer may be related to the regulation of the PI3K/ Akt /mTOR signaling pathway to intervene in ferroptosis.
