OBJECTIVE To build a Tibetan-language medication service platform based on “internet+” and evaluate its effect on improving medication compliance and safety of Tibetan patients with chronic disease. METHODS Medication guidance contents of commonly used drugs in the outpatient department were summarized， translated and recorded in Tibetan-language or video to form a “text-audio-video” multi-dimensional “internet+ ” Tibetan-language medication service platform. A total of 387 Tibetan outpatients with chronic disease in our hospital after the implementation of “internet+” Tibetan-language medication service platform （from January 2024 to June 2024） in our hospital were selected as the intervention group， and 387 Tibetan outpatients before the implementation （from January 2023 to June 2023） were selected as the control group. Patients in the control group received conventional window-based Chinese-language medication services， while patients in the intervention group received both conventional window-based Chinese-language medication service and “internet+ ” Tibetan-language medication service. The medication compliance of patients was evaluated using the 12-item Medication Compliance Scale. A six-level causality assessment was conducted as the principles for analyzing adverse drug reactions （ADR） set by the National Center for ADR Monitoring. Additionally， statistics were compiled on the occurrence of ADR that were assessed as “definite”“probable” or “possible” in the causality assessment. RESULTS The proportion （31.0%） of patients with good medication compliance and compliance scores [39.0 （37.0，42.0）] of patients in the intervention group were significantly better than control group [7.0%， 21.0（19.0， 23.0）]（ P＜0.05）. There were no statistically significant differences in the incidence of various types of ADR or the overall incidence between the two groups （P＞0.05）. CONCLUSIONS The “internet+” Tibetan-language medication service platform is constructed successfully； the service can effectively improve the medication compliance of Tibetan-language patients， but its effect on improving the medication safety of patients is limited.

OBJECTIVES: To investigate the regulatory effects of Aurora-A in regulating proliferation, migration, invasion, and epithelial-mesenchymal transition (EMT) of cervical cancer cells and the role of actin-related protein 2/3 complex subunit 4 (ARPC4) in mediating its effects. METHODS: The plasmids pCDH-NC, pCDH-Aurora-A, and shRNA-ARPC4 were used for inducing Aurora-A overexpression or ARPC4 knockdown in HeLa cells. The cells were divided into vector group, Aurora-A overexpression group, Aurora-A overexpression+ARPC4 knockdown group, and Aurora-A overexpression+NF‑κBp65 inhibitor group and transfected with the corresponding plasmids. The proliferation, colony-forming ability, migration and invasion of the treated Hela cells was evaluated using EdU immunofluorescence assay, crystal violet staining, scratch assay, Transwell assay, and Matrigel assay. Western blotting was performed to detect the changes in cellular expressions of EMT-related proteins and expression levels of NF-κBp65 and ARPC4. RESULTS: The expression of ARPC4 was significantly decreased in HeLa cells with Aurora-A knockdown and increased in Aurora-A-overexpressing cells. Aurora-A overexpression obviously promoted proliferation, migration, and invasion abilities of HeLa cells, and these effects was significantly antagonized by ARPC4 knockdown. In Aurora-A-overexpressing cells, the phosphorylation level of NF-κBp65 and the expression level of ARPC4 were increased significantly, and application of the NF‑κBp65 inhibitor obviously lowered the expression level of ARPC4. CONCLUSIONS Aurora-A overexpression upregulates the expression of ARPC4 by activating the NF-κBp65 signaling pathway, thereby promoting migration, invasion and EMT of HeLa cells.

Objective:To analyze the current status and deficiencies of family bed service policies in China, for references for promoting the construction of China′s home health service system.Methods:Key words such as " family bed" and " home health services" were used to search for relevant policies(from January 1, 1984 to May 31, 2023)in Peking University Treasure Database, the State Council′s policy document repository, and official websites of health administrative departments at all levels. NVivo 11.0 software was utilized for a three-level coding process to establish a policy text analysis framework and to identify deficiencies in the construction of policies.Results:A total of 63 policy documents were included, comprising 53 provincial and municipal documents, which were mainly concentrated in economically developed provinces; After three-level coding, 72 third level nodes, 21 second level nodes, and 8 first level nodes(service objects, service providers, service methods, service content, service fees, subsidy policies, hospital bed configuration, and standardized management) were obtained. Among them, the responsibilities of service providers needed to be further clarified, the technical and innovative nature of service content was still insufficient, the charging standards and medical insurance reimbursement policies needed to be improved, the support for subsidy policies was limited, and the use of intelligent devices in bed configuration needed to be strengthened.Conclusions:China′s family bed service policy focused on eight dimensions, covering a comprehensive range of content, but there were still areas that need to be refined and improved. This study suggested that relevant departments should further clarify the responsibilities of service providers, deepen the construction of service connotations, moderately increase government support, promote the intelligent construction of services, and achieve multi-party collaboration to jointly promote the sustainable development of family bed services in China.

Objective To explore the effect of nicotinamide transmethylase on intracellular reactive oxygen species(ROS)in iron death of hepatocellular carcinoma cells and its mechanism.Methods Methyl nicotinamide(MNA)expression in cells was detected using a tandem liquid chromatography-mass spectrometry.The average fluorescence intensity of ROS and lipid peroxidation was measured using a flow cytometer.Western blot was used to detect changes in the expression of human liver cancer cells(SK-Hep-1,Hep3B).Forty patients with primary hepatocellular carcinoma who received treatment in our hospital from March 2019 to February 2020 were selected as the study subjects,and their adjacent tissue samples and liver cancer tissue samples were collected.Immunohistochemical methods were used to detect the levels of nicotinamide N-methyltransferase(NNMT)and ROS in adjacent and liver cancer tissues.CCK-8 method was used to detect the survival activity of cells with different iron concentrations.Results The MNA levels in the liver cancer tissue group were higher than those in the adjacent tissue group(P<0.05).Compared with the adjacent tissue group,the average fluorescence intensity expression of ROS in the liver cancer tissue group increased,while the average fluorescence intensity expression of lipid peroxidation decreased(P<0.05).Compared with the adjacent tissue group,the expression levels of SK Hep-1 and Hep3B cells in the liver cancer tissue group increased(P<0.05).Compared with the control group,NNMT groups 2,10,20,and 25 μmol/L The cell survival activity level increased(P<0.05);Compared with the NNMT group,the iron inhibition group had different iron concentrations(2μmol/L,10μmol/L,20μmol/L,25μmol/L.The expression of cell viability decreased(P<0.05).Conclusion ROS mediated by nicotinamide methyltransferase can be guided to produce ROS and energy disorders,leading to increased tumor cell death.

Objective:To investigate the serum levels of myeloperoxidase (MPO), interleukin-1β (IL-1β) and transforming growth factor-β1 (TGF-β1) in patients with hyperuric acid gout, and to analyze their correlation and interaction with uric acid.Methods:A total of 120 male patients with hyperuricemia (HUA) diagnosed and treated in the Tenth Affiliated Hospital of Guangxi Medical University (Qinzhou First People′s Hospital) from December 2019 to December 2022 were selected as the study objects, including 55 patients with gout as the observation group and 65 patients without gout as the control group. Serum levels of uric acid, MPO, IL-1β and TGF-β1 were compared between the two groups, Logistic regression was used to analyze the risk factors of HUA with gout, and Pearson test was used to analyze the correlation between serum uric acid level and MPO, IL-1β and TGF-β1 levels, the interactions were calculated by the likelihood ratio test.Results:The levels of serum uric acid, MPO, IL-1β and TGF-β1 in the observation group were higher than those in the control group: (559.63 ± 70.62) μmol/L vs. (448.24 ± 50.49) μmol/L, (0.37 ± 0.10) mmol/L vs. (0.29 ± 0.07) mmol/L, (49.83 ± 5.03) ng/L vs. (42.15 ± 4.77) ng/L, (34.15 ± 6.82) μg/L vs. (28.97 ± 5.14) μg/L, there were statistical differences ( P<0.05). The results of Logistic regression showed that serum uric acid, MPO, IL-1β and TGF-β1 levels were risk factors for hyperuric acid gout ( P<0.05). The results of Pearson test showed that serum uric acid were positively correlated with the levels of MPO, IL-1β and TGF-β1( r = 0.760, 0.775, 0.759, P<0.05), and there was interaction in the pathogenesis of hyperuric acid gout ( P<0.05). Conclusions:The high levels of MPO, IL-1β and TGF-β1 at the same time can increase the risk of hyperuric acid gout.

ObjectiveTo induce the rat model of ulcerative colitis （UC） with spleen-kidney Yang deficiency and liver depression， and explore the efficacy and mechanism of Sishenwan combined with Tongxie Yaofang （SSW&TXYF） based on the therapeutic principles of tonifying spleen， soothing liver， warming kidney， and astringing intestine. MethodSixty male SD rats were randomized into normal， model， mesalazine， and high-， medium-， and low-dose SSW&TXYF groups. The rats in other groups except the normal group were administrated with Sennae Folium decoction and hydrocortisone and received tail clamping for 14 days. On day 14， rats received enema with TNBS-ethanol solution to induce UC. The rats were administrated with corresponding drugs from day 15 of modeling， and the body weight and mental state were observed and recorded. The sucrose preference test was performed from day 25. On day 28， the rectal temperature was measured， and the rats were administrated with 3% D-xylose solution at a dose of 10 mL·kg^-1 by gavage. Blood was sampled 1 h later， from which the serum was collected for measurement of the D-xylose content. The serum， hippocampus， and colorectum samples of rats were collected on day 29. The levels of gastrin （GAS）， adrenocorticotropic hormone （ACTH）， corticosterone （CORT）， cyclic adenosine monophosphate （cAMP）， cyclic guanosine monophosphate （cGMP）， interleukin （IL）-4， tumor necrosis factor （TNF）-α， and interferon （IFN）-γ in the serum and 5-hydroxytryptamine （5-HT） in the hippocampus were determined by enzyme-linked immunosorbent assay. Hematoxylin-eosin staining was employed to reveal the colonic lesions. The mRNA and protein levels of p38 mitogen-activated protein kinase （MAPK）， extracellular signal-regulated kinase （ERK）， and c-Jun N-terminal kinase （JNK） in the colon tissue were determined by Real-time PCR and Western blot， respectively. ResultCompared with the normal group， the model group showed decreased body weight， anal temperature， and D-xylose content in the serum and increased GAS content （P<0.01）. The modeling led to cAMP/cGMP unbalance and decreased the ACTH and CORT content in the serum （P<0.01）， the preference for sucrose water， and the 5-HT content in the hippocampus （P<0.01）. Moreover， it shortened the colorectal length and caused massive infiltration of inflammatory cells and severe structural damage in the colon tissue. High， medium， and low doses of SSW&TXYF improved above indicators （P<0.05， P<0.01）， reduced inflammatory infiltration， and repaired the pathological damage of the tissue. Compared with the normal group， the model group showed lowered IL-4 level （P<0.01） and elevated TNF-α and IFN-γ levels （P<0.05， P<0.01） in the serum， as well as up-regulated expression of p38 MAPK， ERK， and JNK （P<0.05， P<0.01）. Compared with the model group， SSW&TXYF elevated the IL-4 level （P<0.01）， lowered the TNF-α and IFN-γ levels （P<0.05， P<0.01）， and down-regulated the mRNA and protein levels of p38 MAPK， ERK， and JNK （P<0.05， P<0.01）. ConclusionA rat model of UC with spleen-kidney Yang deficiency and liver depression was successfully established. SSW&TXYF can significantly mitigate this syndrome by reducing the inflammatory response in the colon and inhibiting the MAPK pathway.
