Objective: To investigate the objective characteristics of tongue manifestation in different stages of damp-heat syndrome in diabetic kidney disease (DKD). Methods: A cross-sectional study enrolled 134 patients with DKD G3-5 stages who met the diagnostic criteria for damp-heat syndrome in DKD. The patients were treated at Dongzhimen Hospital, Beijing University of Chinese Medicine, from May 2023 to January 2024. The patients were divided into three groups: DKD G3, DKD G4, and DKD G5 stage, with 53, 33, and 48 patients in each group, respectively. Clinical general data (gender, age, and body mass index) and damp-heat syndrome scores were collected from the patients. The YZAI-02 traditional Chinese medicine (TCM) AI Tongue Image Acquisition Device was used to capture tongue images from these patients. The accompanying AI Open Platform for TCM Tongue Diagnosis of the device was used to analyze and extract tongue manifestation features, including objective data on tongue color, tongue quality, coating color, and coating texture. Clinical data and objective tongue manifestation characteristics were compared among patients with DKD G3-5 based on their DKD damp-heat syndrome status. Results: No statistically significant difference in gender or body mass index was observed among the three patient groups. The DKD G3 stage group had the highest age (P<0.05). The DKD G3 stage group had a lower score for symptoms of poor appetite and anorexia(P<0.05) than the DKD G5 group. No statistically significant difference was observed in damp-heat syndrome scores among the three groups. Compared with the DKD G5 stage group, the DKD G3 stage group showed a decreased proportion of pale color at the tip and edges of the tongue (P<0.05). The DKD G4 stage group exhibited an increased proportion of crimson at the root of the tongue, a decreased proportion of thick white tongue coating at the root, a decreased proportion of pale color at the tip and edges of the tongue, an increased hue value (indicating color tone) of the tongue color in the middle, an increased brightness value (indicating color lightness) of the tongue coating color in the middle, and an increased thickness of the tongue coating (P<0.05). No statistically significant difference was observed in other tongue color proportions, color chroma values, body characteristics, coating color proportions, coating color chroma values, and coating texture characteristics among the three groups. Conclusion Tongue features differ in different stages of DKD damp-heat syndrome in multiple dimensions, enabling the inference that during the DKD G5 stage, the degree of qi and blood deficiency in the kidneys, heart, lungs, liver, gallbladder, spleen, and stomach is prominent. Dampness is more likely to accumulate in the lower jiao, particularly in the kidneys, whereas heat evil in the spleen and stomach is the most severe. These insights provide novel ideas for the clinical treatment of DKD.

Objective: To explore the efficacy of vonoprazan fumarate in the treatment of laryngopharyngeal reflux disease（LPRD） evaluated by the Chinese version of the RSS-12 scale. Methods:A total of 100 LPRD patients treated in the otolaryngology-head and neck surgery outpatient clinic of our hospital were randomly divided into two groups（50 cases each）. The observation group was treated with vonoprazan fumarate（20 mg, once daily）, and the control group was treated with esomeprazole enteric-coated capsules（20 mg, twice daily） for 12 weeks. The selected observation indicators in this study included RSI, the Chinese version of RSS-12, and RFS scores before and after treatment. Results:Prior to treatment, there was no statistically significant difference in the Chinese version of RSS-12, RSI, and RFS between the two groups（P>0.05）. After 8 and 12 weeks of antacid treatment, both the Chinese version of RSS-12 and RSI significantly decreased in both group （P<0.05）. The changes in symptoms were particularly noticeable between 0-8 weeks of treatment according to the Chinese version of RSS-12 and RSI. After 12 weeks of treatment, the RFS scores significantly decreased compared to pretreatment levels （P<0.05）. After 12 weeks of antacid treatment, according to the Chinese version of RSS-12, 80% of patients in the observation group showed a good therapeutic response, compared to 64% in the control group; according to RSI, 90% of patients in the observation group showed a good therapeutic response, compared to 84% in the control group. There was no statistically significant difference in the treatment effect between the two groups after 12 weeks of treatment（P>0.05）. Conclusion:Vonoprazan fumarate can significantly improve the symptoms and signs of laryngopharyngeal reflux, and their treatment effect is not inferior to proton pump inhibitors. Compared with RSI, the Chinese version of RSS-12 can serve as a new screening tool for clinical diagnosis of LPRD in China.

Objective To study the effect and mechanism of Anchusa italica Retz on cerebral ischemia-reperfusion inju-ry in rats based on the target network of active compounds in Anchusa italica Retz.Methods The rat model of cerebral ische-mia-reperfusion injury was established by the thread occlusion method.After performing ischemia for 1.5 h and then reperfusion for 24 h,the neurological function of rats was scored and the volume of cerebral infarction was measured by the 2,3,5-triphenyltet-razolium chloride staining method.The molecular network analysis technique of network pharmacology,protein-protein interaction network,gene ontology(GO)enrichment analysis,KEGG signal pathway analysis,and molecular docking was used to study the mechanism of Anchusa italica Retz in the treatment of cerebral ischemia-reperfusion injury.Results The administration of An-chusa italica Retz could significantly improve the neurobehavioral dysfunction caused by cerebral ischemia-reperfusion injury and reduce the pathological injury of brain tissue.Anchusa italica Retz could regulate inflammation,apoptosis,protein phosphorylation,and other biological processes through 143 ischemic stroke-related targets,and interfere with the TNF signal pathway,VEGF signal pathway,HIF-1 signal pathway,and other pathways.Conclusion Network pharmacology and experimental verification had shown that Anchusa italica Retz could effectively reduce brain injury and protect neurological function through multi-target,multi-mechanism,and holistic treatment of cerebral ischemia-reperfusion injury.

Objective:To investigate the effect of feeder layer cells expressing interleukin(IL)-21 on the amplification of NK cells in vitro.Methods:The K562 cell line with IL-21 expression on its membrane was constructed by electroporation,and co-cultured with NK cells after inactivation.The proliferation of NK cells was observed.The killing function of the amplified NK cells in vitro was evaluated by the lactate dehydrogenase(LDH)and interferon-γ(IFN-y)release assay.A colorectal cancer xenograft model in NOD/SCID mice was established,and a blank control group,a NK cell group and an amplified NK cell group were set up to detect the tumor killing effect of amplified NK cells in vivo.Results:K562 cells expressing IL-21 on the membrane were successfully constructed by electroporation.After co-culturing with K562 cells expressing IL-21 on the membrane for 17 days,the NK cells increased to 700 times,which showed an enhanced amplification ability compared with control group(P＜0.001).In the tumor cell killing experiment in vitro,there was no significant difference in the killing activity on tumor cells between NK cells and amplified NK cells,and there was also no significant difference in mice in vivo.Conclusion:K562 cells expressing IL-21 on the membrane can significantly increase the amplification ability of NK cells in vitro,but do not affect the killing function of NK cells in vitro and in vivo.It can be used for the subsequent large-scale production of NK cells in vitro.

The deubiquitinases (DUBs), as the crucial peptidohydrolases in the ubiquitin system, can reverse and strictly regulate ubiquitination and play key roles in various biological processes, including the regulation of protein stability, cell signal transduction. Ubiquitin-specific protease 28 (USP28) involves multiple cancer-related signaling pathways by enhancing the stability of various cancer-related proteins, and is closely associated with the progression of colorectal, breast cancer, lung carcinomas, and pancreatic cancer. USP28 has been considered as a promising drug target in anticancer therapy, and the development of USP28 inhibitors has made some progress. In this article, we review the structure of USP28 and its interaction with substrates, discuss the research progress of USP28 in cancers and summarize the development of USP28 inhibitors.

Objective To explore the mechanisms associated with symptom burden and depression in hepatocellular carcinoma patients after hepatectomy. Methods A total of 230 hospitalized patients with hepatocellular carcinoma who were underwent hepatectomy for the first time were selected as study subjects. A self-administered General Information Questionnaire, MD Anderson Symptom Inventory, Patient Health Questionnaire, Connor-Davidson Resilience Scale, and Pittsburgh Sleep Quality Index were used to investigate sociodemographic, sociodemographic data, symptom burden, depression, psychological resilience, and sleep quality of postoperative hepatocellular carcinoma patients. Pearson correlation analysis was used to identify specific associations among variables. The mediating and moderating effects of psychological resilience and sleep quality between symptom burden and depression were analyzed using the Process. Results Psychological resilience partially mediated the association between symptom burden and depression (β=-0.137, SE=0.084, 95%CI, -0.243 to -0.082), with the mediating effect accounting for 44.08% of the total effect, and the interaction term between symptom burden and sleep quality had predictive value for psychological resilience (β=-0.014, t=-6.209, P < 0.001). Conclusion Postoperative symptom burden in hepatocellular carcinoma patients can play a role in depression through psychological resilience, where the effect of symptom burden on psychological resilience is moderated by sleep quality. Clinical staff should take reducing patients'postoperative symptom burden and improving psychological elasticity with sleep quality as important goals and develop appropriate nursing interventions to reduce the risk of depression in patients.

The modernization and development of traditional Chinese medicine has led to higher standards for the quality of traditional Chinese medicine products. The extraction process is a crucial component of traditional Chinese medicine production, and it directly impacts the final quality of the product. However, the currently relied upon methods for quality assurance of the extraction process, such as simple wet chemical analysis, have several limitations, including time consumption and labor intensity, and do not offer precise control of the extraction process. As a result, there is significant value in incorporating near-infrared spectroscopy (NIRS) in the production process of traditional Chinese medicine to improve the quality control of the final products. In this study, we focused on the extraction process of Xiao'er Xiaoji Zhike oral liquid (XXZOL), using near-infrared spectra collected by both a Fourier transform near-infrared spectrometer and a portable near-infrared spectrometer. We used the concentration of synephrine, a quality control index component specified by the pharmacopoeia, to achieve rapid and accurate detection in the extraction process. Moreover, we developed a model transfer method to facilitate the transfer of models between the two types of near-infrared spectrometers (analytical grade and portable), thus resolving the low resolution, poor performance, and insufficient prediction accuracy issues of portable instruments. Our findings enable the rapid screening and quality analysis of XXZOL onsite, which is significant for quality monitoring during the traditional Chinese medicine production process.

Purpose: This study aimed to explore the impact of ABL1–tyrosine kinase inhibitors (TKIs) adherence on the survival of chromosome-positive (Ph+) acute lymphoblastic leukemia (ALL) children and clarify the potential predictors of patients’ prognosis from TKIs intake practices. Materials and Methods: Ninety newly diagnosed Ph+ ALL patients who received TKIs were enrolled. We collected the baseline characteristics and adverse events in all children; moreover, TKIs adherence was measured by an eight-item Morisky medication adherence scale (MMAS-8). Progression-free survival (PFS) and overall survival (OS) analysis were performed, and risk factors for PFS and OS were evaluated. Results: Among all patients, 69 cases were regarded as adherers, while 21 were non-adherers. The median duration of TKIs interruption was significantly prolonged in the non-adherence group than in the adherence group (13 [0-101] vs. 56 [11-128], p < 0.001). Additionally, dose reduction occurred in 55.2% of non-adherers versus 23.0% of adherers (p=0.002). The PFS and OS in adherers were significantly higher versus non-adherers (p=0.020 and p=0.039). MMAS-8 score was an independent risk factor for PFS (p=0.010) and OS (p=0.031). Among non-adherers, the median OS was only 23.1% (4.2%-42%) in patients aged ≤ 10 years versus 54.4% (38.8%-70%) in adolescents. Most of the patients who experienced TKIs non-adherence suffered pancytopenia. Conclusion TKIs adherence during treatment significantly influenced the survival of pediatric Ph+ ALL patients, and non-adherers with age ≤ 10 years were more vulnerable to TKIs disruption. The cumulative TKIs dose should be especially emphasized to patients with age ≤ 10 years, which may result in an inferior achievement of relevant treatment milestones.

Three-dimensional(3D)cell spheroid models combined with mass spectrometry imaging(MSI)enables innovative investigation of in vivo-like biological processes under different physiological and patho-logical conditions.Herein,airflow-assisted desorption electrospray ionization-MSI(AFADESI-MSI)was coupled with 3D HepG2 spheroids to assess the metabolism and hepatotoxicity of amiodarone(AMI).High-coverage imaging of＞1100 endogenous metabolites in hepatocyte spheroids was achieved using AFADESI-MSI.Following AMI treatment at different times,15 metabolites of AMI involved in N-desethylation,hydroxylation,deiodination,and desaturation metabolic reactions were identified,and according to their spatiotemporal dynamics features,the metabolic pathways of AMI were proposed.Subsequently,the temporal and spatial changes in metabolic disturbance within spheroids caused by drug exposure were obtained via metabolomic analysis.The main dysregulated metabolic pathways included arachidonic acid and glycerophospholipid metabolism,providing considerable evidence for the mechanism of AMI hepatotoxicity.In addition,a biomarker group of eight fatty acids was selected that provided improved indication of cell viability and could characterize the hepatotoxicity of AMI.The combination of AFADESI-MSI and HepG2 spheroids can simultaneously obtain spatiotemporal infor-mation for drugs,drug metabolites,and endogenous metabolites after AMI treatment,providing an effective tool for in vitro drug hepatotoxicity evaluation.
