ObjectiveTo investigate the differences in the regulatory effects of formulas containing Ephedrae Herba and Armeniacae Semen Amarum (Mahuangtang, Sanaotang, and Maxing Shigantang) on thermosensitive transient receptor potential ion channels (thermo TRPs) in the mouse model of asthmatic airway inflammation. MethodsSixty female C57BL/6 mice were allocated into blank, model, dexamethasone (0.75 mg·kg-1), Mahuangtang (3.8 g·kg-1), Sanaotang (2.8 g·kg-1), and Maxing Shigantang (6.6 g·kg-1) groups (n=10). The mouse model of asthma was established with ovalbumin (OVA) and treated with normal saline (blank group) or corresponding drugs (10 mL·kg-1), once a day, 19-28 days after modeling. The levels of eosinophils (EOS) in peripheral blood and white blood cell (WBC) in bronchoalveolar lavage fluid (BALF), changes in enhanced pause (Penh), and pathological damage of lung tissue were observed in each group. Western blot and real-time PCR were employed to quantify the protein and mRNA levels, respectively, of high-temperature thermosensitive channels (TRPV1 and TRPV3) and low-temperature thermosensitive channels (TRPA1 and TRPM8) in the lung tissue. ResultsCompared with the blank group, the model group showed a typical asthma phenotype, including elevations in the level of EOS in peripheral blood, level of WBC in BALF, and value of Penh (P<0.05,P<0.01), and severe lung tissue damage. Compared with the model group, the three formulas alleviated the asthma phenotype to varying degrees (P<0.05,P<0.01). Compared with the blank group, the model group showed up-regulated protein levels of TRPV1 and TRPA1 in the lung tissue (P<0.01). Compared with the model group, Maxing Shigantang and Sanaotang groups showed down-regulated protein levels of TRPV1 and TRPA1 (P<0.05, P<0.01). Moreover, Maxing Shigantang and Sanaotang groups showed more significant down-regulation in protein levels of TRPV1 and TRPA1, respectively (P<0.01), while no obvious regulatory effect was observed in the Mahuangtang group. Compared with those in the blank group, the protein levels of TRPV3 and TRPM8 were up-regulated in the model group (P<0.01). Compared with the model group, Maxing Shigantang and Sanaotang down-regulated the protein levels of TRPV3 and TRPM8 (P<0.01). Moreover, Maxing Shigantang and Sanaotang exerted stronger down-regulating effects on TRPV3 (P<0.05) and TRPM8 (P<0.01), respectively. Compared with the blank group, the model group presented up-regulated mRNA levels of TRPV1, TRPV3, TRPA1, and TRPM8 in the lung tissue (P<0.01), and such up-regulations were significantly decreased by Maxing Shigantang and Sanaotang (P<0.01). Moreover, Maxing Shigantang outperformed Sanaotang in regulating high-temperature thermosensitive channels TRPV1 and TRPV3 (P<0.05, P<0.01). The regulation effect of the, Maxing Shigantang on high-temperature thermosensory channel proteins of TRPV1 and TRPV3 was better than that of the Sanaotang P<0.05P<0.01while the Sanaotang outperformedhad a significant regulatory effect on Maxing Shigantang in regulating the low-temperature thermosensory thermosensitive channel proteins of TRPA1 and TRPM8which was better than that of the Maxing Shigantang (P<0.05,P<0.01). ConclusionThe experimental results showed that Mahuangtang, Sanaotang, and Maxing Shigantang all had protective effects on asthma airway inflammation.while Mahuangtang did not show the regulatory effect on TRPV1 and or TRPA1. Maxing Shigantang preferred to regulate high-temperature thermosensory thermosensitive channels of TRPV1 and TRPV3 channels, and Sanaotang preferred to regulate low-temperature thermosensory thermosensitive channels of TRPA1 and TRPM8.

Objective To explore the diagnostic value of endoscopic grading of gastric intestinal metaplasia (EGGIM) score under acetic acid-enhanced narrow band imaging (AA-NBI) observation mode for gastric intestinal metaplasia (GIM). Methods A total of 120 patients who underwent gastroscopy at Jinshan Hospital of Fudan University from February 2022 to February 2023 were selected. All patients underwent both white light and AA-NBI endoscopy, with photographic records of intestinal metaplasia in five areas: greater curvature of antrum, lesser curvature of antrum, greater curvature of corpus, lesser curvature of corpus and incisura. EGGIM score was performed: 0 for no intestinal metaplasia, 1 point for focal intestinal metaplasia (GIM area ratio≤30%), 2 points for extensive intestinal metaplasia (GIM area ratio>30%), with a total score of 10 points. Targeted biopsies were performed on suspicious GIM lesions found during endoscopy. If no suspicious GIM lesions were observed, random biopsies were performed according to the updated Sydney system. The pathological histological examination results were staged based on the operative link on gastric intestinal metaplasia assessment (OLGIM) system. The diagnostic value of EGGIM score for OLGIM stage Ⅲ-Ⅳ patients was evaluated using receiver operating characteristic (ROC) curves. Results The sensitivity, specificity, accuracy, positive predictive value (PPV), and negative predictive value (NPV) of AA-NBI in detecting GIM were 96.3%, 91.6%, 94.5%, 95.0%, and 93.6%, respectively. The area under the ROC curve for EGGIM diagnosing OLGIM stage Ⅲ-Ⅳ was 0.952 (95%CI 0.914-0.990). The optimal cut-off value for EGGIM was 5 points, with a sensitivity of 96.7% (95%CI 87.6%-99.4%) and specificity of 88.1% (95%CI 76.5%-94.7%). Conclusions EGGIM score (≥5 points) under AA-NBI mode has good diagnostic capability for patients with OLGIM stage Ⅲ-Ⅳ.

Renal tumor scoring systems can describe the anatomical characteristics of renal tumors. It is an important standard to evaluate the surgical complexity and to evaluate the surgical complexity and feasibility of partial nephrectomy. Scholars at home and abroad have established various scoring systems based on different anatomical parameters,such as R.E.N.A.L.,PADUA,C-Index,which are used to guide the clinical selection of surgical modalities,and predict perioperative complications and prognosis. In this paper,various scoring systems are grouped into three major categories according to their functions:prediction of surgical complexity,prediction of complications,and prediction of prognosis. The contents,characteristics and clinical application value of various renal tumor scoring systems are introduced in detail to guide urologists,enhance their surgical decision-making ability,and improve the clinical outcomes.

OBJECTIVE:
To observe the effects of moxibustion at different temperatures on cognitive function and blood glucose levels in patients with cognitive impairment associated with type 2 diabetes mellitus (T2DM).
METHODS:
A total of 66 T2DM patients with cognitive impairment were randomly assigned to a high-temperature group (22 cases, 1 case dropped out, 1 case was eliminated), a medium-temperature group (22 cases, 2 cases were eliminated), and a low-temperature group (22 cases, 2 cases were eliminated). All groups received moxibustion at Baihui (GV20), Dazhui (GV14), and Shenting (GV24) based on their existing glycemic control treatment. Moxibustion temperatures were maintained at 44-46 ℃ (high-temperature group), 41-43 ℃ (medium-temperature group), and 38-40 ℃ (low-temperature group), respectively, for 20 min per session, every other day, 3 times a week for 3 months. The Montreal cognitive assessment (MoCA) score, mini-mental state examination (MMSE) score, short-term memory (STM) accuracy and average reaction time, Rey-Osterrieth complex figure (ROCF) score, fasting plasma glucose (FPG), and glycated hemoglobin (HbA1c) were assessed before and after treatment. Clinical efficacy was evaluated after treatment.
RESULTS:
After treatment, MMSE scores in all three groups were higher than those before treatment (P<0.05). In the high-temperature group, the total MoCA score and the scores of visuospatial and executive function, memory and delayed recall, attention, naming, language, and abstraction were higher than those before treatment (P<0.05); the scores of ROCF copy, immediate recall, and delayed recall were higher than those before treatment (P<0.05); the HbA1c level was lower than that before treatment (P<0.05). In the medium-temperature group, the total MoCA score and the scores of memory and delayed recall, attention, and language were higher than those before treatment (P<0.05). STM accuracy was higher than before treatment (P<0.05), and STM average reaction time was shorter than before treatment (P<0.05) in both the high-temperature and medium-temperature groups. After treatment, the total MoCA score and the scores of visuospatial and executive function, memory and delayed recall, attention, and language in the high-temperature group were higher than those in the medium- and low-temperature groups (P<0.05); MMSE score, STM accuracy, and ROCF immediate recall and delayed recall scores were higher than those in the medium- and low-temperature groups (P<0.05); STM average reaction time was shorter than that in the medium- and low-temperature groups (P<0.05); HbA1c level was lower than that in the low-temperature group (P<0.05). The total MoCA score, attention score, and MMSE score in the medium-temperature group were higher than those in the low-temperature group (P<0.05), and STM average reaction time was shorter than that in the low-temperature group (P<0.05). There were no statistically significant differences in FPG within or between the three groups before and after treatment (P>0.05). The total effective rates were 75.0% (15/20) in the high-temperature group, 50.0% (10/20) in the medium-temperature group, and 15.0% (3/20) in the low-temperature group; the total effective rate in the high-temperature group was significantly higher than that in the low-temperature group (P<0.05).
CONCLUSION
Moxibustion at different temperatures has a dose-effect relationship in treating cognitive impairment in T2DM patients. A temperature range of 44-46 ℃ is more effective in improving cognitive function and stabilizing average blood glucose levels over 2-3 months.

With the rapid development of artificial intelligence, computational pathology has been seamlessly integrated into the entire clinical workflow, which encompasses diagnosis, treatment, prognosis, and biomarker discovery. This integration has significantly enhanced clinical accuracy and efficiency while reducing the workload for clinicians. Traditionally, research in this field has depended on the collection and labeling of large datasets for specific tasks, followed by the development of task-specific computational pathology models. However, this approach is labor intensive and does not scale efficiently for open-set identification or rare diseases. Given the diversity of clinical tasks, training individual models from scratch to address the whole spectrum of clinical tasks in the pathology workflow is impractical, which highlights the urgent need to transition from task-specific models to foundation models (FMs). In recent years, pathological FMs have proliferated. These FMs can be classified into three categories, namely, pathology image FMs, pathology image-text FMs, and pathology image-gene FMs, each of which results in distinct functionalities and application scenarios. This review provides an overview of the latest research advancements in pathological FMs, with a particular emphasis on their applications in oncology. The key challenges and opportunities presented by pathological FMs in precision oncology are also explored.

Most cancers are currently incurable, partly due to abnormal post-translational modifications (PTMs). In this study, we initially used multiple myeloma (MM) as a working model and found that SUMOylation activating enzyme subunit 1 (SAE1) promotes the malignancy of MM. Through proteome microarray analysis, SAE1 was identified as a potential target for bioactive colcemid or its derivative colchicine. Elevated levels of SAE1 were associated with poor clinical survival and increased MM proliferation in vitro and in vivo. Additionally, SAE1 directly SUMOylated and upregulated the total protein expression of p27, leading to LLPS-mediated nuclear export of p27. Our study also demonstrated the involvement of SAE1 in other types of cancer cells, and provided the first monomer crystal structure of SAE1 and its key binding model with colchicine. Colchicine also showed promising results in the Patient-Derived Tumor Xenograft (PDX) model. Furthermore, a controlled clinical trial with 56 MM patients demonstrated the clinical efficacy of colchicine. Our findings reveal a novel mechanism by which tumor cells evade p27-induced cellular growth arrest through p27 SUMOylation-mediated nuclear export. SAE1 may serve as a promising therapeutic target, and colchicine may be a potential treatment option for multiple types of cancer in clinical settings.

To effectively exploit the tumor microenvironment (TME), TME-responsive nanocarriers based on cascade reactions have received much attention. In this study, we designed a novel nanoparticle PB@SiO2@MnO2@P-Arg (PMP) to construct a cascade reaction nanoplatform. While using biosafety Prussian blue (PB) for photothermal therapy (PTT), this nanoplatform uses silica (SiO2) as an intermediate layer to assemble Prussian blue and manganese dioxide (MnO2) into a core-shell structure, which effectively enhances the response of the nanoplatform to TME and promotes the effect of chemodynamic therapy (CDT) resulting from glutathione (GSH) depletion and Fenton-like reaction. The released Mn2+ can also be used for magnetic resonance imaging (MRI). Through the cascade reaction, poly-l-arginine (P-Arg) coated on the surface of the nanoparticles can react with hydroxyl radical (•OH) obtained from the Fenton-like reaction to release nitric oxide (NO), which further reacts with O2•- to produce the more toxic peroxynitrite anion (ONOO-). The photothermal effect of PB further enhances the effect of the cascade reaction while reducing the amount of heat required for treatment. In vitro and in vivo studies confirmed the antitumor effects of cascade reaction-based nanoplatforms in combined photothermal/chemodynamic/gas cancer therapies, providing new strategies for the design and fabrication of multifunctional nanoplatforms that integrate diagnostic and therapeutic functions, as well as the application of cascade reactions in multimodal synergistic therapy.

Phage immunoprecipitation sequencing (PhIP-Seq) is a high-throughput and low-cost method for analyzing the specific binding of target proteins to peptide libraries. The method uses oligonucleotide library synthesis (OLS) to encode proteome-scale peptide libraries for display on phages, and then immunoprecipitates these library phages with target proteins (such as antibodies) for subsequent analysis by high-throughput DNA sequencing. PhIP-Seq enables the screening of peptide targets that react specifically with hundreds of proteins or pathogens. PhIP-Seq has been successfully applied in various fields such as disease detection, screening of autoimmune disease biomarkers, vaccine development, and allergen detection, becoming a high-throughput diagnostic technology. This article systematically describes the development, applications, and result evaluation of PhIP-Seq, in order to gain a more comprehensive understanding of the application and future development prospects of this technology in various fields.

Objective To evaluate the efficacy and safety of modified pelvic floor reconstruction in non-nerve-sparing robot-assisted radical prostatectomy (NNS RARP) for improving postoperative urinary control. Methods A retrospective analysis was conducted on the clinical data of 79 prostate cancer patients who underwent NNS RARP at Tangdu Hospital during Jan.2020 and Dec.2023, including 29 in the reconstruction group, and 50 in the non-reconstruction group. The baseline characteristics including age, body mass index, prostate-specific antigen (PSA) level, clinical stage, prostate volume, and biopsy Gleason score, and perioperative indexes including operation time, intraoperative blood loss, catheter indwelling time, complication rate, and positive rate of surgical margins were compared between the two groups. Additionally, urinary continence function was assessed before operation and 1,3,6, and 12 months after operation using the international consultation on incontinence questionnaire-short form (ICIQ-SF) and the incontinence quality of life questionnaire score (I-QoL). Results No statistically significant differences were observed in the baseline characteristics between the two groups (P>0.05). The operation time was significantly longer in the reconstruction group than in the non-reconstruction group [ (110.24±15.08) min vs. (101.80±9.89) min, P=0.010]. There were no significant differences in intraoperative blood loss, catheter indwelling time, complication rate, and positive rate of surgical margins between the two groups (P>0.05). The reconstruction group demonstrated significantly lower ICIQ-SF scores at 1 month [ (10.17±2.16) vs. (11.56±1.66), P=0.002],3 months [ (7.62±1.29) vs. (9.52±1.80), P<0.001], and 6 months postoperatively [ (4.93±1.22) vs. (6.18± 1.67), P=0.001]compared to the non-reconstruction group (adjusted P<0.0125). Conversely, the I-QoL scores were significantly higher in the reconstruction group at 1 month [ (73.32±10.30) vs. (63.88±9.55), P<0.001]and 3 months postoperatively [ (78.91±4.82) vs. (75.66±5.17), P=0.007] (adjusted P<0.0125). However, no significant differences were found in ICIQ-SF or I-QoL scores between the two groups preoperatively and 12 months postoperatively (adjusted P>0.0125). Conclusion The application of modified pelvic floor reconstruction technique in NNS RARP is safe and feasible. Although it slightly prolongs the operation time, it does not increase surgical risks; instead, it effectively promotes early recovery of postoperative urinary continence, thereby significantly enhancing patients'quality of life.
