Objective:To explore the rehabilitation effects of individual computer story-version magnanimous therapy (ICSMT) on patients with end-stage renal disease undergoing maintenance hemodialysis (MHD).Methods:A total of 120 patients with end-stage renal disease receiving MHD treatment at the Department of Nephrology Hemodialysis Center of Huadu District People's Hospital of Guangzhou from August 2022 to April 2024 were selected as the study subjects.They were randomly divided into control group ( n=60, receiving routine clinical treatment) and ICSMT group ( n=60, receiving routine clinical treatment combined with ICSMT for psychological intervention) by random number table method.The patients in the two groups were evaluated by the self-rating anxiety scale (SAS), self-rating depression scale (SDS), enterprising and magnanimous questionnaire (EMQ), the short-form-36 health survey (SF-36), and activity of daily living scale (ADL) before intervention and at 4-week post-intervention.Blood pressure, blood urea nitrogen (BUN), hemoglobin (Hb), and serum albumin (ALB) levels were also measured before the intervention and at the 4-week post-intervention.The clinical global impression scale (CGI) was used to evaluate clinical efficacy before the intervention, at the 2-week post-intervention, and at the 4-week post-intervention.Statistics analysis was performed using SPSS 29.0.1.0(171). Independent-samples t-test, paired t-test, Mann-Whitney U test and Wilcoxon signed-rank test were used for statistical analysis. Results:After 4 weeks of intervention, the SAS and SDS in the ICSMT group (49.0 (48.0, 50.0), 50.0 (49.0, 51.0)) were significantly lower than those in the control group (51.0 (50.0, 52.0), 52.0 (51.0, 53.0)) (both P<0.001). The enterprising subscore of the EMQ in the ICSMT group (35.0 (32.0, 37.0)) was significantly higher than that in the control group (31.0 (29.0, 34.0)) ( P<0.001). Furthermore, the differences of enterprising and magnanimous subscores between the two groups before and after intervention in the ICSMT group (2.0 (1.0, 4.0), 1.0 (-1.0, 2.0))were significantly higher than those in the control group (-1.0 (-1.0, 0), -1.0 (-1.2, 0)) (both P<0.05). Systolic and diastolic blood pressure values in the ICSMT group (130 (126, 134) mmHg, 85 (80, 88) mmHg)were significantly lower than those in the control group (145 (138, 152) mmHg, 93 (88, 99) mmHg)(1 mmHg=0.133 kPa) after 4 weeks of intervention(both P<0.05). After 4 weeks of intervention, the level of BUN in the ICSMT group (5.5 (3.7, 8.4) mmol/L) was significantly lower than that in the control group (9.1 (6.8, 11.4) mmol/L), while the level of Hb and ALB in the ICSMT group ((115.0±10.0)g/L, (38.3±3.2)g/L)were significantly higher than those in the control group ((104.0±12.0)g/L, (37.1±2.9)g/L) (all P<0.05). After 4 weeks of intervention, the physical functioning, role-physical, general health, vitality, social functioning, role-emotional, and mental health subscores of SF-36 in ICSMT group were all significantly higher than those in the control group (all P<0.05). After 4 weeks of intervention, the score of ADL in the ICSMT group (15.42±1.58)was significantly lower than that in the control group (16.78±2.06) ( t=-4.08, P<0.05). At the 2-week post-intervention and the 4-week post-intervention, the severity of illness (SI) and global improvement (GI) in the ICSMT group were significantly lower than those in the control group, while the efficacy index (EI) in the ICSMT group was significantly higher than that in the control group (all P<0.05). Conclusion:ICSMT can effectively promote the physical, psychological, and social functional rehabilitation of end-stage renal disease patients undergoing MHD, significantly improving their quality of life.

Objective:To investigate the prevalence of infectious diarrhea among older adult patients with schizophrenia, identify the influential factors, and construct a nomogram prediction model for infectious diarrhea.Methods:This study is a prospective cohort study that used convenience sampling to select 160 older patients with schizophrenia from three psychiatric hospitals in Wenzhou (85 cases from Wenzhou Seventh People's Hospital, 40 cases from Lucheng Third People's Hospital, and 35 cases from The Affiliated Kangning Hospital of Wenzhou Medical University) who were admitted between January 2022 and December 2023. The prevalence of infectious diarrhea and its influential factors were statistically analyzed. Regression analysis was conducted to develop a risk prediction model for infectious diarrhea, which was presented using a nomogram.Results:A total of 160 older adult patients with schizophrenia were aged between 61 and 79 years, with an average age of (67.82 ± 7.56) years. Among these patients, 53 were female (33.13%), and 107 were male (66.87%). Thirty-four patients experienced infectious diarrhea, with an incidence rate of 21.25%. Univariate analysis revealed significant differences in body mass index ( χ2 = 9.36, P = 0.009), history of diarrhea ( χ2 = 4.52, P = 0.033), disinfection of tableware ( χ2 = 4.16, P = 0.04), handwashing before and after meals ( χ2 = 6.11, P = 0.013), intestinal flora disorder ( χ2 = 19.43, P < 0.001), CD 4+/CD 8+ ratio ( t = 12.37, P < 0.001), interleukin-17 ( t = 15.86, P < 0.001), and fecal secretory IgA ( t = 20.18, P < 0.001) in older adult patients with schizophrenia. Multifactorial analysis indicated that body mass index ( OR = 0.733), disinfection of tableware ( OR = 0.733), handwashing before and after meals ( OR = 0.452), CD 4+/CD 8+ ratio ( OR = 0.359), interleukin-17 ( OR = 0.563), and fecal secretory IgA ( OR = 0.455) were protective factors against infectious diarrhea in older adult patients with schizophrenia (all P < 0.05). Conversely, a history of diarrhea ( OR = 1.774) and intestinal flora disorder ( OR = 1.528) were identified as risk factors for infectious diarrhea in this population (both P < 0.05). Conclusions:The influential factors for the occurrence of infectious diarrhea in older adult patients with schizophrenia include body mass index, history of diarrhea, disinfection of tableware, handwashing before and after meals, intestinal flora disorder, CD 4+/CD 8+ ratio, interleukin-17, and fecal secretory IgA levels. Future studies should conduct longitudinal research to optimize the prediction model and establish a dynamic nomogram model. This will provide nurses with a reliable tool for dynamically predicting the occurrence of infectious diarrhea in older adult patients with schizophrenia, with the aim of reducing the incidence of infectious diarrhea and improving the patients' quality of life.

Objective:To explore the current status of nutrition impact symptoms in patients with liver cirrhosis and to explore its influencing factors.Methods:Convenience sampling was used to select liver cirrhosis inpatients from three ClassⅢ Grade A hospitals in Fuyang City, Anhui Province, from November 2022 to November 2023 for the study. General Information Questionnaire, Eating Symptoms Questionnaire (ESQ), Perceived Social Support Scale (PSSS), and Simplified Coping Style Questionnaire (SCSQ) were used to investigate the participants. Binary Logistic regression was used to explore the factors that influence nutrition-impact symptoms in liver cirrhotic patients.Results:A total of 394 questionnaires were distributed, and 384 valid questionnaires were recovered, with an effective recovery rate of 97.5%. Of the 384 patients with liver cirrhosis, 274 patients (71.4%) had at least one nutrition impact symptom, and 166 patients (43.2%) had at least one moderate-to-severe nutrition impact symptom. Patients' most common nutrition impact symptoms include dry mouth, altered taste, and bloating. Binary Logistic regression analysis showed that age, liver cirrhosis stage, total bilirubin, coping styles, and social support were the influencing factors of nutrition impact symptoms in patients with liver cirrhosis, and the differences were statistically significant (all P<0.05) . Conclusions:The detection rate of nutrition impact symptoms in patients with liver cirrhosis is high. Healthcare professionals can alleviate moderate-to-severe nutrition impact symptoms by guiding patients to adopt positive coping styles and helping to improve social support.

Chronic heart failure （CHF） is the final stage of cardiovascular diseases. It is a complex syndrome， with dyspnea and edema as the main clinical manifestations， and it is characterized by complex disease conditions， difficult cure， and high mortality. Ferroptosis， a new type of programmed cell death， is different from other types of programmed cell death. Ferroptosis is iron-dependent， accompanied by lipid peroxide accumulation and mitochondrial shrinkage， becoming a hot research topic. Studies have confirmed that ferroptosis plays a key role in the occurrence and development of CHF. The regulation of ferroptosis may become a potential target for the treatment of CHF in the future. The theory of Qi deficiency and stagnation refers to the pathological state of original Qi deficiency and abnormal transportation and distribution of Qi， blood， and body fluid， which has guiding significance for revealing the pathogenesis evolution of some chronic diseases. We believe that Qi deficiency and stagnation is a summary of the pathogenesis of ferroptosis in CHF. Deficiency of Qi （heart Qi） is the root cause of CHF， and stagnation （phlegm turbidity and blood stasis） is the branch of this disease. The two influence each other in a vicious circle to promote the development of this disease. Traditional Chinese medicine （TCM） plays an important role in the treatment of CHF， improving the prognosis and quality of life of CHF patients. This paper explores the correlation between the theory of Qi deficiency and stagnation and the mechanism of ferroptosis in CHF. Furthermore， this paper reviews the mechanism of Chinese medicines and compound prescriptions in preventing and treating CHF by regulating ferroptosis according to the principles of replenishing Qi and dredging to remove stagnation， aiming to provide new ideas and methods for the treatment of CHF with TCM.

Objective:To investigate a novel coating technology for artificial blood vessel pipelines, conducting preliminary tests on the mechanical stability, hemocompatibility, and biocompatibility of the coating.Methods:The polyester braided artificial blood vessels produced by Terumo Corporation were subjected to three different experimental treatments and divided into three groups. Model group: The uncoated artificial blood vessels were thoroughly cleaned and freeze-dried. Experimental group: The artificial blood vessels were first immersed in a dopamine solution to form a polydopamine(PDA) coating on their surface, and then further immersed in an earthworm active protein/gelatin(EWAP/GT) solution to create PDA/GT/EWAP-modified artificial blood vessels. Collagen group: The untreated polyester woven artificial blood vessels served as the control. The study detailed the characterization, porosity, water permeability, degradation rate, blood compatibility, and cytotoxicity of the PDA/GT/EWAP-coated artificial blood vessels. Additionally, a 2-week in vivo study was conducted to evaluate the biocompatibility of the PDA/GT/EWAP-coated artificial blood vessels implanted subcutaneously in SD rats.Results:The PDA/GT/EWAP-coated artificial vascular grafts were successfully fabricated. The artificial blood vessels in the PDA/GT/EWAP group exhibited a porosityof(50.53±1.10)%, with water permeability showing a gradual decreasing trend over time. The overall in vitro degradation rate at 4 weeks was(1.83±0.08)%, and the PDA/GT/EWAP group demonstrated favorable mechanical stability. The activated partial thromboplastin time(APTT) of the PDA/GT/EWAP group was(26.30±0.46)s, the thrombin time(TT) was(18.83±0.49)s, the hemolysis rate was(2.15±0.09)%, and the plasma recalcification time(PRT) was(191.00±10.54)s, indicating excellent blood compatibility and anticoagulant properties. MTT assay evaluation of the PDA/GT/EWAP group revealed no significant cytotoxicity. After subcutaneous implantation of vascular samples in rats for 2 weeks, analysis of blood immune parameters and hematoxylin-eosin(HE) staining of the artificial vascular samples showed that the immune response in the PDA/GT/EWAP group exhibited no significant difference compared to the collagen group and was superior to the model group. Conclusion.Conclusion:The PDA/GT/EWAP composite-coated artificial blood vessel demonstrates excellent mechanical properties, good hemocompatibility, biocompatibility, and low cytotoxicity. It also shows remarkable stability. This research offers a new approach for domestic technological breakthroughs in related fields.

Objective By using ultrasonography to calculate the ratio of optic nerve sheath diameter(ONSD)at 3 mm behind eyeball to the eyeball transverse diameter(ETD),based on which to evaluate the effect of dexmedetomidine on intracranial pressure(ICP)in patients with intracranial aneurysm after receiving interventional embolization under general anesthesia.Methods A total of 40 patients with intracranial aneurysm,who were scheduled to receive interventional embolization under general anesthesia at the Affiliated Lihuili Hospital of Ningbo University of China from May 2023 to November 2023,were selected for this study.By using random number table method,the patients were divided into control group(group C)and dexmedetomidine group(group D)with 20 patients in each group.Standardized anesthesia strategy was adopted in both groups.For patients of group D,a loading dose of dexmedetomidine was pumped at a velocity of 1 μg/(kg·h)for 10 min before the surgery,the pumping was continued at 0.5 μg/(kg·h)velocity during the operation,and the pumping stopped half an hour before the end of the operation.For patients of group C,the same anesthesia strategy was used,while no any special treatment was given.At the different time points,including before awakening(T0),immediately after extubation(T1),and 5 min(T2),10 min(T3),15 min(T4)after extubation,ONSD at 3 mm behind eyeball and ETD were measured by transorbital ultrasonography,and ONSD/ETD ratio was calculated to evaluate ICP.The mean arterial pressure(MAP),heart rate(HR),blood oxygen saturation(SPO2),severity of cough,and extubation time were recorded at the time to remove the catheter.Results Compared with the data obtained at T0,the ONSD/ETD ratios obtained at T1 and T2 were increased in both groups(P＜0.05),while the ONSD/ETD ratios obtained at other time points were not significantly different from the ONSD/ETD ratio obtained at T0(P＞0.05).Compared with Group C,in Group D the ONSD/ETD ratios obtained at T1 and T2 were smaller,the differences were statistically significant(P＜0.05).The incidence of moderate to severe cough in Group D was lower than that in Group C(P＜0.05).Compared with Group C,in Group D the HR and MAP determined at the time of removing catheter were lower(P＜0.05).The extubation time in Group D was longer than that in group C,the difference was statistically significant(P＜0.05).Conclusion ONSD/ETD ratio calculated by ultrasono-graphy can objectively reflect the changes of ICP during the extubation period.Dexmedetomidine can reduce the elevation degree of ICP through effectively inhibiting cough reflex and circulatory fluctuation during tracheal extubation.However,dexmedetomidine may increase the incidence of adverse events such as bradycardia,delayed extubation,etc.

ObjectiveTo observe and compare the effects of different concentrations of cyclophosphamide (CTX) in inducing premature ovarian insufficiency (POI) model in mice and investigate the mechanism of injury. MethodsThirty-two 6~8-week-old female C57BL/6J mice were randomly divided into four groups (n=8 per group) using a weight-based block randomization method. The POI model was established via a single intraperitoneal injection of 75 mg/kg cyclophosphamide (CTX), 120 mg/kg CTX, 120 mg/kg CTX + 12 mg/kg Busulfan, or an equivalent volume of normal saline (control). Ovarian coefficients, serum estradiol (E₂) and follicle-stimulating hormone (FSH) levels were measured. Western blotting was performed to assess changes in ovarian expression levels of NAD-dependent deacetylase sirtuin-5 (SIRT5) and forkhead box O3a (FOXO3a) under different modeling conditions. After determining the optimal CTX concentration for modeling, an additional forty 6~8-week-old femal C57BL/6J mice were randomly divided into five groups (n=8 per group) using a weight-based block randomization method: saline control, 120 mg/kg CTX sampling at 1, 2, 7, or 14 days after modeling. Western blotting was used to evaluate temporal changes of ovarian SIRT5 and FOXO3a protein expression. ResultsCompared with the saline control, all concentrations of CTX (75 mg/kg CTX, 120 mg/kg CTX) and 120 mg/kg CTX + 12 mg/kg Busulfan induced POI injury in mice. The 120 mg/kg CTX group exhibited smaller changes in ovarian coefficients (P<0.001) and E₂ levels (P<0.05), whereas the 120 mg/kg CTX + 12 mg/kg Busulfan group showed rough and reduced luster fur, sluggish response and was in the worst state. Compared with the saline control group, FOXO3a expression was significantly down-regulated (P<0.05), while SIRT5 remained unchanged in the 75 mg/kg CTX group (P>0.05). In contrast, both SIRT5 (P<0.05) and FOXO3a (P<0.05) were significantly down-regulated in the 120 mg/kg CTX group. Further analysis revealed that on day 2 and 7 after 120 mg/kg CTX modeling, the expressions of SIRT5 (P<0.01) and FOXO3a (P<0.001) were significantly down-regulated, with the largest decrease observed on day 7 (SIRT5, P<0.000 1; FOXO3a, P<0.000 1). ConclusionOvarian injury in the POI model induced by 120 mg/kg CTX is milder than that in the POI model induced by 75 mg/kg CTX. Moreover, the expression changes of SIRT5 and FOXO3a are most significant on day 7 after modeling induced by 120 mg/kg CTX, which may be related to the inhibition of the SIRT5-FOXO3a signaling pathway.

OBJECTIVES: To propose a hypothesis that aloe-emodin may inhibit scar tissue fibrosis through thrombospondin-1(THBS1)-PI3K-Akt pathway. METHODS: By cultivating fibroblasts derived from scar tissue after cleft palate surgery in humans, aloe emodin of different concentrations (10, 20, 30, 40 and 50 μmol/L) was added to the cells which activity was detected. At the same time, transcriptome sequencing was performed on scar tissue and cells, and bioinformatics methods were used to explore potential targets and signaling pathways of scar tissue fibrosis. RESULTS: Aloe-emodin had a concentration dependent inhibitory effect on fibroblast proliferation,with the 40 μmol/L concentration group showing the most significant effect. The results of tissue and cell sequencing indicated that differentially expressed genes were significantly enriched in extracellular matrix-receptor interaction pathway, and shared a common differential gene which was THBS1. The ORA analysis results indicated that differentially expressed genes, including THBS1, were significantly enriched in the PI3K-Akt signaling pathway. CONCLUSIONS Aloe emodin may inhibit the PI3K-Akt pathway by downregulating THBS1, thereby reducing the proliferation activity of fibroblasts derived from postoperative palatal scar tissue.

Objective:To explore the correlation between hyperuricemia (HUA) and chronic kidney disease (CKD) in the individuals undergoing physical examinations.Methods:It was a retrospective cohort study. The study selected 6 910 individuals who received health check-ups at the Xiangya Hospital Health Management Center of Central South University in 2012 and 2022, with none of them having developed CKD in 2012. Using the presence of HUA in 2012 as the independent variable and the occurrence of CKD in 2022 as the outcome variable, four Cox proportional hazards regression models were constructed, with baseline age, gender, body mass index, waist circumference, glomerular filtration rate, presence of hypertension, presence of diabetes, presence of dyslipidemia, white blood cell count, hemoglobin level, direct bilirubin level, alanine aminotransferase level, and blood uric acid level in 2013 as confounding variables. These models were used to analyze the correlation between HUA and CKD, and sensitivity analyses were conducted. The percentile bootstrap method was employed to conduct mediation effect testing, analyzing the intermediary risk factors that influence the correlation between HUA and CKD.Results:Among the 6 910 participants included in the study, the overall baseline detection rate of HUA was 8.78% (607/6 910). In 2022, the incidence of CKD was 7.2% (498/6 910). Cox regression analysis showed a positive correlation between HUA and the occurrence of CKD in the overall population ( HR=1.586, 95% CI: 1.224-2.055). However, after gradually adjusting for confounding factors, the correlation between HUA and CKD was not statistically significant. Stratified by gender, the occurrence of HUA was positively correlated with the incidence of CKD in women ( HR=2.599, 95% CI: 1.069-6.316), but the correlation became non-significant after adjusting for confounding factors. In contrast, there was no significant correlation between HUA and CKD in men. In sensitivity analysis, When uric acid levels were analyzed by grouping participants into two categories based on thresholds of>420 μmol/L for men and>360 μmol/L for women, or as a continuous variable, the results showed a positive correlation between HUA and CKD in the overall population and in women, the HR (95% CI) value was 1.627 (1.282-2.064), 2.465 (1.552-3.914), 1.004 (1.003-1.005) and 1.006 (1.004-1.008), respectively. However, after adjusting for confounding factors, the correlation between HUA and CKD became non-significant in both cases. In the males, there was no correlation between uric acid and the occurrence of CKD, regardless of whether uric acid was treated as a categorical or continuous variable. Mediation analysis revealed that diabetes and hypertension were full mediators between HUA/blood uric acid levels and CKD in the overall population. Among males, diabetes and hypertension were full mediators between blood uric acid levels and CKD. In females, hypertension was a full mediator between HUA/blood uric acid levels and CKD, with an effect proportion of 100%. Conclusion:HUA is positively correlated with the risk of CKD, particularly in females, but HUA is not an independent predictor of CKD. HUA influences the occurrence of CKD through conditions such as diabetes and hypertension.
