ObjectiveThis study aims to understand the recognition of practitioners in traditional Chinese medicine （TCM） hospitals on hospital-based health technology assessment （HB-HTA）， assessment needs， challenges， and suggestions， so as to provide references for the future work. MethodThe convenient sampling method was adopted to survey the relevant practitioners in TCM hospitals. The questionnaire included 39 questions in 4 dimensions and was distributed through the online platform Weijuanxing. ResultA total of 244 questionnaires were recovered， and the obtained data were analyzed in SPSS. The results showed that 137 practitioners were very familiar with HB-HTA and there was no significant difference in the recognition of practitioners in different occupations （F=0.251； P=0.778）. The practitioners in Hong Kong， Macao， and Taiwan had lower recognition than those in other regions. In terms of the assessment needs， 127 practitioners believed that it was very necessary to carry out HB-HTA in TCM hospitals in the future. Chinese patent medicines/Chinese herbal medicine decoction pieces （5.91） and TCM appropriate technology （5.57） had higher assessment priority scores. The assessment needs were high for the effectiveness （235 practitioners） and safety （224 practitioners） of health technology. The lack of specialized organization and standardized evaluation process system and the shortage of talents were considered to be the major challenges for the future development in this field. ConclusionThe stakeholders carrying out the health technology assessment in TCM hospitals had certain awareness of HB-HTA. Most practitioners believed that it was necessary to carry out HB-HTA in TCM hospitals in the future， while the work might face challenges such as the lack of organizations and system and the shortage of talents， which requires policy support.

We retrospectively analyzed therapy efficacy and the adverse reactions of 10 patients suffering from systemic lupus erythematosus (SLE) with intestinal involvement treated with rituximab (RTX). Patients were hospitalized in the Department of Rheumatology and Immunology of the First Medical Center of PLA General Hospital from January 2015 to January 2023. Among the 10 patients, two were men and eight were women. The age of the cohort was (41.9±8.8) years. The age at disease onset was (28.8±9.2) years. The total course of the SLE diagnosis was(109.6±59.9) months. The course of the diagnosis of SLE with intestinal involvement was (89.3±50.2) months. The time from the appearance of intestinal symptoms to the diagnosis of SLE with intestinal involvement was 1.5 (1.0,8.0) months. The time from the diagnosis of SLE with intestinal involvement to RTX use was 13.0 (1.0,46.3) months. Follow-up duration after application of RTX treatment was (55.3±28.4) months. There were five cases of abdominal pain, four cases of abdominal distension, nine cases of diarrhea, three cases of nervous-system involvement, nine cases of lupus nephritis, and seven cases of serositis. All 10 patients underwent computed tomography and radiology of the abdomen. Eight patients had intestinal-wall edema, seven suffered intestinal dilation, four had target signs, three suffered congestion of mesenteric blood vessels, eight had increased mesenteric-fat density, and six had false intestinal obstruction. All 10 patients showed a low level of complement C3 (250-750 mg/L). Nine cases showed a low level of complement C4 (10-90 mg/L). The SLE disease activity index 2000 (SLEDAI-2K) at baseline in 10 patients was 20.5 (17.8, 30.0). After receiving RTX (0.5 g: day 1, day 14, or 375 mg/m 2: day 1, day 14) induction treatment, the intestinal symptoms of 10 cases were relieved completely. Four patients had adverse reactions, of which three received a high-dose glucocorticoid combined with RTX treatment simultaneously. Adverse reactions manifested mainly as a reduced level of IgG and infection with herpes simplex virus in one case, reduced level of IgG and lung infection in one patient, lung infection in one case, and reduced IgG level in one patient. RTX may an efficacious treatment strategy for patients suffering from refractory SLE with intestinal involvement.

BACKGROUND:Animal models of diabetic encephalopathy that have been studied mainly include streptozotocin-induced model,high-sugar and high-fat diet-induced model and spontaneous animal model.Establishing a simple,easy,short-cycle,safe and effective model of diabetic encephalopathy can help to explore the subsequent pathogenesis and screen therapeutic drugs. OBJECTIVE:To further explore and evaluate the method of building diabetic encephalopathy rat models. METHODS:Twenty Sprague-Dawley rats were randomly divided into control(n=10)and model(n=10)groups.Rats in the model group were given a single injection of 45 mg/kg streptozotocin in the left lower abdominal cavity,and those in the control group were given the same amount of citrate buffer.During the experiment,the body mass,feed intake,water intake and blood glucose were measured.After 8 weeks,the glucose tolerance and oxidative stress levels were measured,and the pathological changes of brain tissue and the expression of apoptotic proteins were compared between groups. RESULTS AND CONCLUSION:Compared with the control group,the food intake,water intake,encephalization quotient,blood glucose and area under the blood glucose curve were significantly increased in the model group,while the body mass decreased significantly(P<0.01).Histopathological examination of the brain showed that compared with the control group,the number of surviving nerve cells was significantly reduced in the model group(P<0.01),with more significant pathological damage of nerve cells.Compared with the control group,the activities of serum superoxide dismutase,catalase and glutathione in the model group were significantly decreased(P<0.01),and the content of oxidative malondialdehyde was significantly increased(P<0.05).The expression levels of apoptosis-related proteins Bax and Caspase-3 in brain tissue increased in the model group compared with the control group,while the expression of Bcl-2 decreased(P<0.01).In conclusion,an 8-week injection of 45 mg/kg streptozotocin can cause obvious pathological damage to the brain tissue of diabetic rats,to successfully establish the rat model of diabetic encephalopathy.

Objectives:To identify the risk factors associated with delirium in intensive care unit (ICU) hospitalization of sepsis patients and construct a clinical prediction model to to provide a reference for the prevention and control of delirium in sepsis patients.Methods:Data were collected of sepsis patients admitted in the Intensive Care Unit in the Second Affiliated Hospital of Soochow University from September 2020 to August 2022.The patients were divided into delirium group and non-delirium group according to whether delirium occurred or not. Comparing of the differences in general and clinical data between the two groups, the independent risk factors for delirium were screened by backward stepwise regression method, and the delirium risk prediction model was constructed and evaluated. An independent risk factor analysis for delirium was conducted using a backward stepwise regression approach to identify significant predictors. A delirium risk prediction model was constructed based on the identified risk factors, followed by a comprehensive evaluation of the model's performance.Results:A total of 381 sepsis patients were included in the study, 114 patients (29.9%) developed delirium during the ICU hospitalization. Univariate analysis revealed statistically significant differences ( P< 0.05) between the delirium and non-delirium groups for several factors including age ≥ 65 years, blood transfusion, use of midazolam, use of adrenaline, APACHEⅡ score>15, SOFA score>4, metabolic acidosis, urea>7.1 mmol/L, coagulation disorders, lactate levels, and platelet count. Multivariate analysis identified age ≥ 65 years, use of midazolam, APACHEⅡ score>15, metabolic acidosis, urea>7.1 mmol/L, and coagulation disorders as independent risk factors for delirium in sepsis patients during ICU hospitalization.The predictive model was evaluated with an area under the ROC curve of 0.813, a non-significant Hosmer-Lemeshow goodness-of-fit test ( P=0.957>0.05), and a Brier score of 0.149 (<0.25), indicating good predictive performance and calibration. Clinical decision and impact curves demonstrated the model's favorable clinical applicability. Conclusions:The occurrence of delirium in ICU sepsis patients closely associate with six factors: age ≥ 65 years, use of midazolam, APACHEⅡ score>15, metabolic acidosis, urea>7.1 mmol/L, and coagulation disorders. This sepsis delirium prediction model has good clinical predictive ability and clinical applicability.

Objective:To observe the effect of metformin on intestinal metabolites and its protective effect on lung injury in an elderly sepsis rat.Methods:SD rats were fed at the Animal Laboratory Center of Zhengzhou University, fourteen elderly SD rats were randomly divided into three groups: sham surgery (age-Sham, AgS group, n=4), cecal ligation and perforation induced sepsis (age-Cecal ligation and puncture, AgCLP group, n=5), and oral administration of metformin (100 mg/kg) after 1 h of CLP treatment (age-Metformin, AgMET group, n=5). Collected rat feces 24 h after modeling, and analyzed the composition and inter group differences of metabolites in the feces using liquid chromatography tandem mass spectrometry non targeted metabolomics. Collected rat lung tissues and detected the expression levels of inflammation related genes and pathological changes in the tissue. The visualization of metabolic changes between groups were presented using orthogonal partial least squares discriminant analysis, heatmaps, and unsupervised principal component analysis, respectively. MetaboAnalyst 3.0 was used to evaluate the Pathway analysis of metabolites, and this software was based on the KEGG database and the human metabolome database. Results:The expressions of CCL4 ( F=203.00, P<0.001), CXCL1( F=65.69, P<0.001), IL-6 ( F=38.94, P<0.002), TNF-α ( F=14.85, P=0.005) between two groups of rats were significantly different (all P<0.05). However, there was no significant difference in CCL2 expression between AgCLP group and AgMET group. Furthermore, compared with the AgS group, the relative intensities of 17 metabolites such as 7-methylxanthine, N-Arachidonylglycine and Manolide in AgCLP group were significantly increased, whereas the 9 metabolites such as Phenazone, Gly-Phe and Valyproline were significantly decreased, and metformin treatment could reverse these changes of the above metabolites. Correlation analysis showed that the IL-6 and TNF-α levels were positively correlated with the relative strength of 7-Methylxanthine, N-Arachidonylglycine and other metabolites, but negatively correlated with the Phenazone and Gly-Phe. CCL4 and CXCL1 were positively correlated with Manolide, but negatively correlated with Valyproline. Conclusion:The results of this study showed that metformin improved sepsis induced acute lung injury and regulates the host intestinal metabolites, which might provide a potential and effective treatment for elderly sepsis induced acute lung injury.

Objective:To conduct a visual analysis of domestic and international research on kinesiophobia to explore recent advancements and trending topics within the field and to provide references for future research in China.Methods:Literature published from 2015 to 2022 retrieved from Chinese databases such as China National Knowledge Infrastructure, Wanfang data, and VIP, and those published from 2009 to 2022 from the Web of Science, was analyzed using CiteSpace software. This analysis summarized and examined the number of publications, authors, collaborating institutions, and keywords, etc.Results:Both domestic and international publications on kinesiophobia showed an increasing trend in recent years, with international publications consistently outnumbering domestic ones. The most prolific authors were Cai Libai and Vlaeyen, and the leading institutions were the First Affiliated Hospital of Zhengzhou University and Maastricht University. Domestic research primarily involved intra-team collaborations with less inter-institutional cooperation, whereas international collaborations were more extensive. Key research topics identified through keyword analysis included kinesiophobia, pain, and movement, with frontiers in risk factors, clinical outcomes, and psychological health.Conclusions:There is a noticeable gap between domestic and international research on kinesiophobia. China should further focus on the emerging hotspots and trends in this field to enhance the prevention and intervention strategies for kinesiophobia research.

Objective:To explore the influence of social exclusion on the relapse tendency of female drug re-hab patients,and the mediating role of self-esteem and the moderating role of positive psychological capital.Method:A total of 288 female drug rehabilitation patients were selected,and the Social Exclusion Question-naire(SEQ)was used to assess the degree of social exclusion experienced by the patients.The Relapse Tendency Questionnaire(RPQ)was used to evaluate the current tendency of drug relapse.The Rosenberg Self-Esteem Scale(RSES)was used to evaluate the self-esteem level of the patients,and the Positive Psychological Capital Question-naire(PPCQ)was used to evaluate their level of positive psychological capital.Results:The SEQ scores of female drug rehab patients were positively correlated with the RPQ scores(β=0.41,P＜0.001),The RSES scores had a mediating effect between the scores of SEQ and RPQ,with a mediation effect size of 0.09(95％CI:0.04-0.15,accounting for 20.6％of the total effect).The PPCQ scores had a moderating effect between the scores of RSES and RPQ(β=-0.08,P＜0.05)and between the scores of SEQ and RPQ(β=0.10,P＜0.05).Conclusion:So-cial exclusion could not only directly affect but also indirectly affect the relapse tendency through self-esteem of fe-male drug rehab patients.Positive psychological capital could moderate the relationship between social exclusion,self-esteem,and relapse tendency.

Although carbon monoxide (CO)-based treatments have demonstrated the high cancer efficacy by promoting mitochondrial damage and core-region penetrating ability, the efficiency was often compromised by protective autophagy (mitophagy). Herein, cannabidiol (CBD) is integrated into biomimetic carbon monoxide nanocomplexes (HMPOC@M) to address this issue by inducing excessive autophagy. The biomimetic membrane not only prevents premature drugs leakage, but also prolongs blood circulation for tumor enrichment. After entering the acidic tumor microenvironment, carbon monoxide (CO) donors are stimulated by hydrogen oxide (H₂O₂) to disintegrate into CO and Mn²⁺. The comprehensive effect of CO/Mn²⁺ and CBD can induce ROS-mediated cell apoptosis. In addition, HMPOC@M-mediated excessive autophagy can promote cancer cell death by increasing autophagic flux via class III PI3K/BECN1 complex activation and blocking autolysosome degradation via LAMP1 downregulation. Furthermore, in vivo experiments showed that HMPOC@M+ laser strongly inhibited tumor growth and attenuated liver and lung metastases by downregulating VEGF and MMP9 proteins. This strategy may highlight the pro-death role of excessive autophagy in TNBC treatment, providing a novel yet versatile avenue to enhance the efficacy of CO treatments. Importantly, this work also indicated the applicability of CBD for triple-negative breast cancer (TNBC) therapy through excessive autophagy.

Mitochondrial encephalomyopathy, lactic acidosis, and stroke-like episodes(MELAS) is one of the most common inherited mitochondrial diseases. This paper reports a rare mutation associated with MELAS syndrome, the m. 3252 A>G mutation in the MT-TL1 gene encoding the mitochondrial tRNALeu(UUR). The 6-year-old girl suffered from recurrent convulsion and lactic acidemia. The mtDNA sequencing detected a variant m. 3252A>G(MT-TL1 gene) in the proband and her maternal relatives. The heteroplasmic levels in peripheral blood and urine sediment were 66.53% and 97.42%, respectively, which were obviously higher than those of her maternal relatives. Together with 3 previously reported cases, the variant m. 3252A>G could be classified pathogenic. All the reported pathogenic variants in MT-TL1 gene were reviewed to explore the genotype-phenotype correlations of pathogenic variants in MT-TL1 gene.
