The concept of holism is the core idea of traditional Chinese medicine （TCM）. Various organs and tissues coordinate with each other to maintain the body's life activities， with a close and mutual influence between the spleen， stomach， and the central nervous system （brain）. The gut-brain axis plays an important bridging role between the digestive system and the central nervous system， achieving bidirectional information exchange between the brain and the gastrointestinal tract through complex neuroendocrine and immune mechanisms. The theory of cross-organ interaction involves the mutual influence， coordination， and integration between different organs and systems； multimodality， on the other hand， utilizes multiple sensory modalities， such as vision， hearing， and touch， to convey information. By combining TCM theory with the gut-brain axis theory， a cross-organ multimodal characterization system is established to explore its mechanism and application value in refractory diseases such as functional gastrointestinal disorders， precancerous gastrointestinal diseases， Alzheimer's disease， Parkinson's syndrome， type 2 diabetes， and depression.

OBJECTIVE To systematically investigate the current status and effectiveness of the standardized on-the-job training program for community clinical pharmacists in Shanghai， and to provide a scientific basis for optimizing the training scheme. METHODS A questionnaire survey was conducted to collect the data from trainees and mentor pharmacists who participated in the program between 2016 and 2024. The survey examined their basic information， evaluations of the training scheme， satisfaction with training outcomes， and suggestions for improvement. Statistical analyses were also conducted. RESULTS A total of 420 valid responses were collected， including 340 from trainees and 80 from mentor pharmacists. Before training， only 30.29% of trainees were engaged in clinical pharmacy-related work， whereas this proportion increased to 73.24% after training. Most mentor pharmacists had extensive experience in clinical pharmacy （76.25% with ≥5 years of experience） and mentoring （78.75% with ≥3 teaching sessions）. Totally 65.59% of trainees and 55.00% of mentor pharmacists believed that blended training yielded the best learning outcomes. Over 80.00% of both trainees and mentor pharmacists considered the overall training duration， theoretical study time， and practical training time to be reasonable. More than 95.00% of trainees and mentor pharmacists agreed that the homework and assessment schemes were appropriate. Trainees rated the relevance of training content to their actual work highly （with an average relevance score ＞4.5）， though they perceived the chronic disease medication therapy management module as significantly more challenging than the prescription review and evaluation module and the home-based pharmaceutical care module. The average satisfaction score of trainees and mentor pharmacists with the training effectiveness of each project was above 4 points， indicating a high overall satisfaction. Inadequate provision of teaching resources was unanimously recognized by trainees and mentor pharmacists as the key area requiring improvement. CONCLUSIONS The standardized on-the-job training program for community clinical pharmacists in Shanghai has contributed to improving pharmaceutical services in community healthcare settings. However， ongoing improvements must concentrate on content design， resource development， and faculty cultivation.

T-cell acute lymphoblastic leukemia (T-ALL) is a highly aggressive hematologic malignancy with a poor prognosis, despite advancements in treatment. Many patients struggle with relapse or refractory disease. Investigating the role of the super-enhancer (SE) regulated gene ubiquitin-specific protease 20 (USP20) in T-ALL could enhance targeted therapies and improve clinical outcomes. Analysis of histone H3 lysine 27 acetylation (H3K27ac) chromatin immunoprecipitation sequencing (ChIP-seq) data from six T-ALL cell lines and seven pediatric samples identified USP20 as an SE-regulated driver gene. Utilizing the Cancer Cell Line Encyclopedia (CCLE) and BloodSpot databases, it was found that USP20 is specifically highly expressed in T-ALL. Knocking down USP20 with short hairpin RNA (shRNA) increased apoptosis and inhibited proliferation in T-ALL cells. In vivo studies showed that USP20 knockdown reduced tumor growth and improved survival. The USP20 inhibitor GSK2643943A demonstrated similar anti-tumor effects. Mass spectrometry, RNA-Seq, and immunoprecipitation revealed that USP20 interacted with hypoxia-inducible factor 1 subunit alpha (HIF1A) and stabilized it by deubiquitination. Cleavage under targets and tagmentation (CUT&Tag) results indicated that USP20 co-localized with HIF1A, jointly modulating target genes in T-ALL. This study identifies USP20 as a therapeutic target in T-ALL and suggests GSK2643943A as a potential treatment strategy.

Objective:Study on the correlation between the active components of Salviea Miltiorrhizae Radix et Rhizoma screened by high-throughput sequencing and the regulation of lncRNA-mRNA in human lung adenocarcinoma A549 cells.Methods:A549 cells were cultured, and the IC 50 dose of cryptotanshinone and tanshinone ⅡA was confirmed according to the cell proliferation experiment. A549 cells were randomly divided into blank control group, cryptotanshinone group, and tanshinone IIA group using a random number table method. After 24 hours of intervention, the cell cycle was detected by flow cytometry. High-throughput sequencing technique was used to detect the expressions of lncRNA and mRNA in A549 cells in intervention group and non-intervention group. By analyzing the expression profiles of differential genes related to cryptotanshinone and tanshinone ⅡA, the obtained differential genes were analyzed by GO and KEGG. Results:The cell cycle results showed that the proportion of G0/G1 phase cells in cryptotanshinone and Tanshinone ⅡA was increased ( P<0.01), the proportion of S phase cells was decreased ( P<0.01), and the proportion of G2/M phase cells in cryptotanshinone was decreased ( P<0.01). The results of high-throughput screening showed that cryptotanshinone could up-regulate 4 698 lncRNA, down-regulate 1 557 lncRNA, up-regulate 4 810 mRNA and down-regulate 5 644 mRNA. Tanshinone ⅡA could up-regulate 1 348 lncRNA, down-regulate 1 299 lncRNA, up-regulate 4646 mRNA and down-regulate 4 741 mRNA. The function and pathway enrichment analysis of differential lncRNA and mRNA showed that the differentially expressed genes of cryptotanshinone and tanshinone ⅡA were mainly related to cell cycle, autophagy, AMPK signaling pathway, FoxO signaling pathway and EGFR signaling pathway. GAS5 may be one of the targets for the inhibitory effects of cryptotanshinone and tanshinone ⅡA. Conclusion:Cryptotanshinone and tanshinone ⅡA have certain inhibitory effects on A549 cells, and there are differentially expressed genes of lncRNA-mRNA, which are closely related to cell cycle and signal pathway.

Objective Neuromuscular electrical stimulation(NMES)-evoked kinesthetic information in muscle spindle can be purely extracted from the mixed motor and sensory afferents using Ischemic nerve block(INB).This study aims to investigate the somatosensory cortical response evoked by NMES activating muscle spindle afferents in forearm.Methods All subjects performed four experimental tasks designed according to a 2×2 factors,including one factor of the INB state(without INB and within INB)and the other of the stimulation intensity(above and below motor threshold).During the experiment,we recorded EEG data with 64 channels and then beta event-related desynchronization(Beta ERD)were utilized quantize somatosensory cortical excitability evoked by the tasks.The subjective perception about the sensation and movement of the right hand were evaluated by a psychophysical test after the right wrist was performed by INB.Results INB significantly reduced beta ERD on the contralateral somatosensory cortex evoked by NMES above the motor threshold,and there was significant difference of NMES-evoked beta ERD values on the contralateral somatosensory cortex between above and below motor threshold.Meanwhile,contralateral dominance of NMES-evoked beta ERD on the somatosensory cortex was transferred to ipsilateral hemisphere under INB.Conclusion INB can significantly reduce NMES-evoked somatosensory cortical response above motor threshold and decrease cortical perception on the stimulus intensity,which may be due to INB resulting in rapid functional reorganization of somatosensory cortex.

Objective:To explore the involvement of miR-126 and the role of mammalian target of rapamycin (mTOR)/hypoxia-induced factor 1 α (HIF-1 α) pathway in regulating human umbilical cord mesenchymal stem cells (hUCMSCs) exosomes (Exo) on vascular endothelial growth factor (VEGF)-A levels in high glucose-induced human retinal vascular endothelial cells (HRECs).Methods:The hREC was cultured in EGM-2-MV endothelial cell culture medium with 30 mmol/L glucose and placed in hypoxic cell incubator by 1% oxygen concentration.

Conclusions:miR-126 plays a role in regulating the effect of hUCMSCs exosomes on VEGF-A levels in high glucose-induced HRECs via mTOR-HIF-1 α pathway.

Dementia is a neurodegenerative disease closely related to brain network dysfunction. In this study, we assessed the interdependence between brain regions in patients with early-stage dementia based on phase-lock values, and constructed a functional brain network, selecting network feature parameters for metrics based on complex network analysis methods. At the same time, the entropy information characterizing the EEG signals in time domain, frequency domain and time-frequency domain, as well as the nonlinear dynamics features such as Hjorth and Hurst indexes were extracted, respectively. Based on the statistical analysis, the feature parameters with significant differences between different conditions were screened to construct feature vectors, and finally multiple machine learning algorithms were used to realize the recognition of early categories of dementia patients. The results showed that the fusion of multiple features performed well in the categorization of Alzheimer's disease, frontotemporal lobe dementia and healthy controls, especially in the identification of Alzheimer's disease and healthy controls, the accuracy of β-band reached 98%, which showed its effectiveness. This study provides new ideas for the early diagnosis of dementia and computer-assisted diagnostic methods.

Background::Transplant renal artery stenosis (TRAS) is a vascular complication after kidney transplantation associated with poor outcomes. This study aimed to analyze the efficacy and safety of low-dose aspirin for preventing TRAS.Methods::After kidney transplantation, patients were enrolled from January 2018 to December 2020 in Henan Provincial People’s Hospital. A total of 351 enrolled recipients were randomized to an aspirin group with low-dose intake of aspirin in addition to standard treatment ( n = 178), or a control group with only standard treatment ( n = 173). The patients was initially diagnosed as TRAS (id-TRAS) by Doppler ultrasound, and confirmed cases were diagnosed by DSA (c-TRAS). Results::In the aspirin and control groups, 15.7% (28/178) and 22.0% (38/173) of the recipients developed id-TRAS, respectively, with no statistical difference. However, for c-TRAS, the difference of incidence and cumulative incidence was statistically significant. The incidence of c-TRAS was lower in the aspirin group compared with the control group (2.8% [5/178] vs. 11.6% [20/173], P = 0.001). Kaplan–Meier estimates and Cox regression model identified the cumulative incidence and hazard ratio (HR) of TRAS over time in two groups, showing that recipients treated with aspirin had a significantly lower risk of c-TRAS than those who were not treated (log-rank P = 0.001, HR = 0.23, 95% confidence interval [CI]: 0.09–0.62). The levels of platelet aggregation rate ( P < 0.001), cholesterol ( P = 0.028), and low-density lipoprotein cholesterol ( P = 0.003) in the aspirin group were decreased compared with the control group in the third-month post-transplantation. For the incidence of adverse events, there was no statistical difference. Conclusion::Clinical application of low-dose aspirin after renal transplant could prevent the development of TRAS with no significant increase in adverse effects.Trial Registration::Clinicaltrials.gov, NCT04260828.
