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.

The detection rate of animal-derived low-dose antibiotics that reside in pregnant women's bodies is relatively high, and the cumulative effect impacts the establishment of the neonatal gut microbiota, leading to an imbalance in the microbial community structure. Exposure to low-dose antibiotics may have adverse effects on the health of pregnant women, fetuses, and newborns. This article reviews the impact of continuous low-dose antibiotic exposure during pregnancy on the establishment and colonization of neonatal gut microbiota, the alteration of the diversity of the neonatal gut microbiota, and the adverse effects on long-term growth and development.

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.

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.

Objective To analyze the short-term survival and prognostic quality of life of patients with liver cirrhosis complicated by bacterial infection. Methods This study collected and analyzed 300 patients with liver cirrhosis complicated with infection who were hospitalized in the First Affiliated Hospital of Hebei North University, and followed up to discuss their survival and quality of life. Results In this study, the top two causes of infection were spontaneous bacterial peritonitis (60.67% of patients) and pneumonia (50.67% of patients). The second causes were urinary tract infections (15.33%), gastrointestinal infections (12.33%), and other causes. There was no statistically significant difference between male and female patients (P>0.05). In addition, the proportion of hospital infections was 71.00%, and there was no statistically significant difference between male and female patients (P>0.05). A total of 353 strains of pathogenic bacteria were isolated in this study (73.37% of patients with hospital infections). The distribution analysis of pathogenic bacteria showed that the highest proportion of ECO was 35.98%, followed by Klebsiella pneumoniae (18.98%). The distribution trend of 259 strains of pathogenic bacteria among hospital patients was consistent with that of all strains, and the difference was not statistically significant (P>0.05). Gram negative bacteria accounted for 79.60% (281/353) of all detected strains, of which Escherichia coli was mostly detected in patients with spontaneous bacterial peritonitis, Klebsiella Pneumoniae (KPN) and Pseudomonas aeruginosa (PAE) were mostly detected in patients with pneumonia, and Enterococcus (ENF) was mostly detected in patients with urinary tract infection; Among gram-negative bacteria, Staphylococcus epidermidis (SEP) and Staphylococcus aureus (SAU) are mostly found in patients with other infectious causes (blood flow infection, etc.) , and Streptococcus (STR) accounts for a high proportion in patients with Spontaneous bacterial peritonitis. In this study, 9 cases of death prognosis were detected during follow-up, and there was no statistically significant difference in the detection of death prognosis between different bacterial strains in both genders, as well as the difference in detection of death prognosis between hospital infections and out of hospital infections in both genders (P>0.05). There was no statistically significant difference in the detection of death prognosis between males and females due to different causes of infection, P>0.05. The quality of life scores of 291 surviving patients were compared between baseline and follow-up, indicating an increase in follow-up scores, especially in the dimensions of physiological function and physical pain. There was no statistically significant difference between different bacterial strains, infection causes, and hospital/non hospital infections (P>0.05) . Conclusion Spontaneous bacterial peritonitis and pneumonia are the main causes of infection that deserve special attention, and the main pathogens of infection are Gram negative bacteria. Targeted treatment and rehabilitation should be provided for patients with liver cirrhosis complicated by infection. At the same time, the proportion of hospital infections is relatively high, and attention should be paid to, prevention and control measures should be implemented as well.

Objective To analyze the correlation between serum miR-939 and miR-15b expression and mi-crovascular injury in patients with diabetic retinopathy(DR).Methods A total of 176 patients with type 2 di-abetes diagnosed and treated in the Baoding Second Hospital from January 2021 to October 2022 were selected as the study objects.The subjects were divided into 74 patients without DR(NDR group),62 patients with non-proliferative DR(NPDR group)and 40 patients with proliferative DR(PDR group)according to whether or not DR occurred and the degree of lesions.Real-time fluorescent quantitative PCR was used to detect the relative expression levels of miR-939 and miR-15b in serum of all groups,the level of vascular endothelial growth factor(VEGF)was detected by enzyme-linked immunosorbent assay,and the count percentage of en-dothelial cells(ECs),endothelial progenitor cells(EPCs)and circulating progenitor cells(CPCs)was detected by flow cytometry.Serum levels of miR-939,miR-15b,VEGF and ECs,EPCs and CPCs were compared in 3 groups.Pearson correlation was used to analyze the correlation between serum miR-939 and miR-15b and VEGF,ECs,EPCs and CPCs.Multivariate Logistic regression was used to analyze the factors affecting the oc-currence of DR in patients with type 2 diabetes.Results The relative expression levels of miR-939 and miR-15b in PDR group and NPDR group were lower than those in NDR group,while the serum VEGF levels were higher than those in NDR group,with statistical significance(P＜0.05).ECs in PDR group and NPDR group were higher than those in NDR group,while EPCs and CPCs were lower than those in NDR group,the differ-ence was statistically significant(P＜0.05).Serum miR-939 was negatively correlated with VEGF and ECs(r=-0.407,-0.613,P＜0.05),and positively correlated with EPCs and CPCs(r=0.481,0.486,P＜0.05).Serum miR-15b was negatively correlated with VEGF and ECs(r=-0.539,-0.625,P＜0.05),and positively correlated with EPCs and CPCs(r=0.451,0.483,P＜0.05).Multivariate Logistic regression anal-ysis showed that the duration of type 2 diabetes,hemoglobin A1c,2-hour postprandial blood glucose,VEGF,miR-939 and miR-15b were the influencing factors for the occurrence of DR in type 2 diabetes patients(P＜0.05).Conclusion The expression of miR-939 and miR-15b in serum of DR patients is closely related to VEGF,ECs,EPCs and CPCs,and the expression of miR-939 and miR-15b in serum of DR patients can provide a certain reference for early judgment and evaluation of the degree of microvascular injury.

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.

BACKGROUND:The abnormal gait of stroke patients seriously affects their propulsive force during walking,which subsequently reduces their walking speed,walking distance,and stability,increases their risk of falls,and seriously affects their quality of life. OBJECTIVE:To review the relevant research on propulsive force deficits in stroke patients with hemiplegia,to summarize the understanding of existing researchers on propulsive force deficits,to analyze the relationship between propulsive force and gait,and finally to explain and compare the latest rehabilitation technologies used to improve propulsive force deficits,providing reference for clinical treatment. METHODS:Relevant literature was retrieved from WanFang,CNKI,PubMed,and Web of Science Core Collection through computer search.The Chinese and English search terms were"propulsive force OR propulsive,stroke OR cerebral infarction OR hemiplegia,walk* OR gait."The search time limit was from 2003 to 2023,and 71 articles were finally included for review and analysis. RESULTS AND CONCLUSION:Training targeting the hip and ankle joints may be more effective for patients'walking function,especially training with the application of flexible exoskeleton robots,but more sufficient evidence is still needed to use propulsion as a prognostic indicator of walking function in stroke patients.Biomechanical variables related to propulsive force include:the hip joint extension angle at terminal stance,ankle joint dorsiflexion torque,and knee joint extension.Damage to the corticospinal tract,cerebellar-cortical pathways,and the reticulospinal tract in hemiplegic patients are associated with reduced propulsive force and gait asymmetry.Propulsive force is crucial for the stability of healthy gait,and a decrease in propulsive force is unfavorable for gait stability.Gait symmetry is correlated with propulsive force,stride length symmetry,trunk displacement,and lower limb swing ability,with propulsive force being a key factor.Propulsive force can serve as a quantitative indicator for assessing the gait of hemiplegic patients,and evaluation of gait using propulsive force is beneficial for the long-term development of walking ability.Main rehabilitation techniques for improving propulsive force include:lower limb exoskeleton robot walking training,treadmill training combined with functional electrical stimulation,adaptive speed treadmill training,biofeedback technology,and whole-body vibration training.Among them,whole-body vibration training and biofeedback technology are more effective.The specific contributions and mechanisms of the hip,knee,and ankle joints in improving propulsive force are still controversial,but it is expected that the contributions of the hip and ankle joints are greater.Focusing on the improvement of propulsive force as a rehabilitation goal may yield more sustainable advancements in walking function.However,several current challenges persist in this field:understanding the neurobiological basis of propulsive force deficits in stroke patients,assessing the long-term efficacy of current rehabilitation techniques for enhancing propulsive force,and determining the most suitable patient populations for the application of major rehabilitation techniques aiming at improving propulsive force.These areas require further exploration by subsequent researchers.
