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.

In September 2023， the Measures for Scientific and Technological Ethics Review （Trial Implementation） was issued， revising the provisions related to the simplified procedure for ethical review in Chapter 3， Section 3. This revision of these provisions provides systematic guarantees for further optimizing ethical review work， ensuring that ethical review procedure is well-regulated， and improving scientific research efficiency. The “simplified procedure” does not mean reducing the quality and requirements of the review. Instead， based on always following internationally recognized ethical standards and emphasizing not violating national laws and regulations， improving the efficiency of ethical review and subsequent research work， and promoting the development of life sciences and medical research involving humans. In practical work， it introduces numerous new opportunities and challenges for the improvement of ethics review ability， such as new tests on the judgment and decision-making power of ethics committees， how to ensure the reliability and controllability of the conditions related to the simplified review procedure， and how to determine the basic conditions for adopting the simplified review procedure for review. Therefore， to actively respond to the challenges and possible risks brought by the simplified procedure review， efforts should be made to achieve three “unifications”， including the unification of researchers’ moral autonomy and the heteronomy of supervision implemented by relevant departments； the unification of the standard formulation of the simplified procedure review and the review work in practice； and the unification of ethical responsibility and legal responsibility.

Hepatic encephalopathy is a difficult and critical disease with rapid progression and limited treatment methods in the field of liver disease， and it is urgently needed to make breakthroughs in its pathogenesis. Selection of appropriate prevention and treatment strategies is of great importance in delaying disease progression and reducing the incidence and mortality rates. This article reviews the theory of “turbid toxin pathogenesis” and related prevention and treatment strategies for hepatic encephalopathy in traditional Chinese medicine/Zhuang medicine， proposes a new theory of “turbid toxin pathogenesis”， analyzes the scientific connotations of “turbid”， “toxin”， and the theory of “turbid toxin pathogenesis”， and constructs the “four-step” prevention and treatment strategies for hepatic encephalopathy， thereby establishing the new clinical prevention and treatment regimen for hepatic encephalopathy represented by “four prescriptions and two techniques” and clarifying the effect mechanism and biological basis of core prescriptions and techniques in the prevention and treatment of hepatic encephalopathy， in order to provide a reference for the prevention and treatment of hepatic encephalopathy.

OBJECTIVE To evaluate the cost-effectiveness of ripretinib versus sunitinib as a second-line treatment option for patients with advanced gastrointestinal stromal tumors （GIST）. METHODS Based on the data of INTRIGUE study， a dynamic Markov model was constructed， with a cycle of 6 weeks； this model was used to simulate patients’ direct medical costs and quality- adjusted life years （QALYs） over 15 years. Using the incremental cost-effectiveness ratio （ICER） as the evaluation metric， a comparison was made between the ICER and the willingness-to-pay （WTP） threshold （3 times the per capita gross domestic product， which amounts to 268 200 yuan/QALY）. One-way sensitivity analyses and probabilistic sensitivity analyses were performed on the model outputs to examine the stability of the model. RESULTS The health benefits of ripretinib were lower than those of sunitinib （1.21 QALYs vs. 1.31 QALYs）. Still， the costs were higher （323 401.88 yuan vs. 227 532.40 yuan）， making it an inferior regimen. The results of the one-way sensitivity analysis suggested that the cost of ripretinib and sunitinib， and the health utility value in progression-free survival status had a greater impact on the ICER of the model. Probabilistic sensitivity analysis suggested that the results of the study were stable， and the probability of the cost-effectiveness advantage of ripretinib was always much lower than that of sunitinib with the increase of WTP threshold， and showed a decreasing trend. CONCLUSIONS In the current economic context of China， ripretinib does not have a cost-effectiveness advantage over sunitinib as a second-line treatment for advanced GIST.

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.

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 mine the adverse drug event （ADE） signals of selinexor， and to provide reference for its clinical safety medication. METHODS ADE data for selinexor reported from July 3rd， 2019 to March 31st， 2023 were collected from the FDA adverse event reporting system （FAERS）. Data mining was performed by using the reporting odds ratio （ROR） and proportional reporting ratio （PRR） methods， and categorization statistics were performed by using the system organ class （SOC） and preferred term （PT） from drug ADE terminology set in the MedDRA （version 26.0）. RESULTS A total of 3 084 ADE reports were obtained for selinexor， with a total of 134 ADE-positive signals. Among the reported genders， there were 127 males and 124 females， with a predominant age of ≥65 years old （4.12%）； the United States had the highest number of reports （96.53%）， with consumers being the main reporters （77.27%）； severe ADR was mainly characterized by hospitalization/prolonged hospitalization （26.26%）， followed by death （17.15%）. The top 3 ADE in the list of frequency were nausea （1 162 times）， fatigue （790 times） and anorexia （610 times）， all of which were mentioned in the selinexor’s instructions. The top 3 signals in the list of strength were device-associated bacteremia （ROR＝115.07， PRR＝114.94）， blepharospasm dysfunction （ROR＝106.70， PRR＝106.54）， and salmonella sepsis （ROR＝99.90， PRR＝99.81）， all of which were not mentioned in the selinexor’s instructions. CONCLUSIONS In addition to the ADE of nausea mentioned in the instruction manual， attention should also paid to device-associated bacteremia， blepharospasm dysfunction， salmonella sepsis， and other ADE not mentioned in the instruction manual when using selinexor in clinical practice； weekly rechecking of the patient’s blood routine should be done to monitor the patient’s blood indexes， symptoms of infection， and so on， to ensure that the safety of 1661962346@qq.com drug use.

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.

Objective To analyze the consistency between computer tomography angiography(CTA)and digital subtraction angiography(DSA)in evaluating the global limb anatomic staging system(GLASS)stage of patients with chronic limb-threatening ischemia(CLTI).Methods The clinical data of patients with CLTI,who were admitted to the First Affiliated Hospital of Xi'an Jiaotong University of China to receive treatment between January 2017 and December 2020,were retrospectively analyzed.Taking the DSA assessment as the gold standard,the consistency of CTA and DSA in evaluating the GLASS stage of patients with CLTI was analyzed.Results In the assessment of GLASS stage of CLTI,CTA showed strong agreement with DSA.The weighted Kappa coefficient of CTA and DSA for the staging of femoropopliteal segment was 0.798(95％CI=0.722-0.873,P＜0.01),and the weighted Kappa coefficient of CTA and DSA for the staging of infrapopliteal artery segment was 0.785(95％ CI=0.725-0.845,P＜0.0l).For the overall staging of GLASS,the weighted Kappa coefficient of CTA and DSA was 0.832(95％ CI=0.752-0.91 1,P＜0.01).All the above results indicated that a very strong consistency existed between CTA and DSA in evaluating the GLASS stage of patients with CLTI.Conclusion CTA examination of lower limb can accurately evaluate GLASS score and stage of CLTI patient's target lesions,which is helpful in diagnosing lower extremity arteriosclerosis occlusion disease as well as in assessing the technical difficulty degree of its revascularization operation.(J Intervent Radiol,2024,33:300-303)

Objective To investigate the impact of SARS-CoV-2 infection on male semen quality through meta-analysis and retrospec-tive study.Methods Literature retrieval was conducted in PubMed,CNKI,Wanfang Database and CBM database.Meta-analysis was performed using Stata 15.0.The male patients meeting the inclusion criteria from our hospital were enrolled as study subjects.General demographic data and semen parameters were collected.Single factor analysis of variance and graphing of semen parameters were con-ducted using GraphPad Prism 9.5.1.The test level was set at 0.05.Results A total of 9 studies involving 267 patients were included in the meta-analysis.There were no significant differences in sperm concentration and survival rate before and after SARS-CoV-2 infec-tion(P＞0.05).Semen volume and percentage of normal morphology significantly increased during 1-3 months after infection(P=0.005,P=0.010),with semen volume recovering to pre-infection level＞3 months later(P＞0.05).Sperm motility and progressive mo-tility increased＞3 months after infection(P=0.046,P=0.045),recovering to pre-infection levels(P=0.099,P=0.098).Sperm DNA fragmentation index may be temporarily elevated within 3 months after infection but gradually decreased＞3 months later.In the retrospective study of 8 cases,there were no statistical differences in semen parameters at different stages compared with pre-infection(P＞0.05),but semen parameters showed a negative trend during＜1 month after infection and recovered to pre-infection levels＞3 months later.Conclusion The results of this laboratory study are basically consistent with the meta-analysis.SARS-CoV-2 infection in males only caused short-term negative effects on sperm morphology,vitality and DNA integrity,but generally recovered to pre-infection levels＞3 months after infection.Due to the limitations of study subjects and sample size,the impact of SARS-CoV-2 infection on male semen quality needs to be further confirmed by long-term large-scale prospective studies.
