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 This study investigated the protective effects of Corni Fructus ethanol extract on β-amyloid protein 25-35 (Aβ25-35)-induced Alzheimer's disease (AD) mice by regulating histone lysine-specific demethylase 1 (LSD1) / postsynaptic density protein 95 (PSD95) on synapses and neuroinflammation. Methods Specifically, according to the body weight, 40 C57BL/6N mice were randomized into four groups: the sham operation group, the model group, the low-dose (0.1mg/g) and the high-dose (0.3 mg/g) Corni Fructus ethanol extract groups. Aβ25-35 was injected into the hippocampus of mice in three groups except for the sham operation group to established AD model. All mice were orally administered with either Corni Fructus ethanol extract or vehicle by gavage for 7 days before molding and continued 5 days after surgery for a total of 60 days. Morris water maze, Y maze and open field tests were performed to evaluate the recognition memory and space exploration ability of mice. The expression of LSD1, PSD95, synaptophysin (SYN), interleukin-1β (IL-1β), tumor necrosis factor-α(TNF-α) and H3K9me2 level were measured by Western blotting. Chromatin immunoprecipitation (CHIP) combined with qPCR was used to detect H3K9me2 modification of PSD95 promoter region and mRNA levels of PSD95. The correlation between the expression of H3K9me2 and PSD95 and the expression of IBA1 in the hippocampus were detected by immunofluorescence assay.Results The result showed that Corni Fructus ethanol extract significantly reversed Aβ25-35-induced learning and memory impairment in AD mice. Compared with the model group, Corni Fructus ethanol extract demonstrated shorter escape latency, increased number and time of autonomous activities and the rate of autonomous alternation. Moreover, it increased the expression of LSD1 in hippocampus of AD mice(P<0.05), and reduced H3K9me2 modification level in the promoter region of PSD95 gene, and then promoted the mRNA transcription and protein expression of PSD95. Immunofluorescence staining indicated the reduction of H3K9me2 modification level in hippocampus was accompanied by the enhancement of PSD95 expression. Corni Fructus ethanol extract could also inhibit the activation of microglia and reduce the expression of proinflammatory factors IL-1β and TNF-α.Conclusion Corni Fructus ethanol extract may regulate PSD95 gene transcription by up-regulating the expression of LSD1 and reducing the H3K9me2 modification level in its promoter region, thereby increasing the expression of PSD95, a key protein in synaptic plasticity regulation, which alleviate neuroinflammatory response, improve learning and memory dysfunction in AD model mice, and thus play a protective role in Aβ25-35-induced nerve damage.

Objective:To report a case of acute kidney injury caused by rhabdomyolysis and summarize its etiology, pathogenesis, and treatment strategy.Methods:The clinical data of a case of rhabdomyolysis complicated by acute kidney injury admitted to Affiliated Huadu Hospital of Southern Medical University on August 30, 2020, were collected, including clinical manifestation, auxiliary examination, and disease outcome. Referring to the previous literature reports of rhabdomyolysis complicated by acute kidney injury, this paper discusses its etiology, monitors and analyzes some indicators such as serum creatinine, blood urea nitrogen, creatine kinase, myoglobin, and 24-hour urine volume during the treatment, and summarizes the clinical diagnosis and treatment ideas of the disease.Results:This case developed an intestinal infection after an unclean diet, which induced rhabdomyolysis and acute kidney injury. Renal pathology after renal biopsy showed that renal biopsy result was consistent with an acute tubulointerstitial injury caused by myoglobin tubular nephropathy. The biochemical indexes such as creatine kinase and myoglobin decreased rapidly after ordinary hemodialysis, but the levels of serum creatinine and blood urea nitrogen did not decrease markedly, and there was continuous oliguria. After switching to hemodialysis filtration and continuous intensive dialysis treatment, the levels of serum creatinine and blood urea nitrogen decreased rapidly, the amount of urine increased gradually, and finally, the renal function recovered.Conclusion:For acute kidney injury caused by rhabdomyolysis, early sufficient blood purification can accelerate the clearance of myoglobin, promote the recovery of the injured kidney, and improve the prognosis of the disease.

Objective:To investigate the characteristics of cardiac structure and function changes in maintenance hemodialysis (MHD) patients.Methods:The information of 363 MHD patients with dialysis age ≥3 months who were registered in Huadu District People′s Hospital of Guangzhou City before January 2020 was collected, and the echocardiographic screening was performed to analyze the changes in cardiac structure and function.Results:The most common abnormal changes of heart structure and function in MHD patients were valve regentation (69.7%), left ventricular hypertrophy (LVH) (51.8%), left ventricular diastolic dysfunction (29.8%), valve calcification (11.6%), and left ventricular systolic dysfunction (10.2%). With the increase of age, the left ventricular ejection fraction of MHD patients decreased, and the proportion of left ventricular diastolic dysfunction, left atrial enlargement and pulmonary hypertension increased (all P<0.05). Among 363 MHD patients, 188(51.8%) had LVH. It was found that LVH patients had higher average single ultrafiltration volume, higher brain natriuretic peptide (BNP) level, more type 2 diabetes, lower left ventricular ejection fraction (all P<0.05), and were more prone to chest tightness, chest pain, post activity shortness of breath, heart failure and other symptoms compared with the non-LVH patients (all P<0.05). Conclusions:Most MHD patients have different degrees of cardiac structural changes. Early intervention, reduction of single ultrafiltration volume and control of blood glucose are beneficial to improve the dialysis quality of MHD patients and reduce the occurrence of cardiovascular events.

Objective:To analyze the incidence of malignant tumors and its risk factors in patients on maintenance hemodialysis.Methods:Clinical data of 627 hemodialysis patients in Huadu District People′s Hospital of Guangzhou who met the inclusion criteria and exclusion criteria from January 2015 to December 2020 were retrospectively collected. Clinical characteristic of patients with malignant tumors was summarized. Multivariate logistics regression analysis was performed to explore the related factors of malignant tumors.Results:Among the 627 patients, 19(3.03%) developed malignant tumors. There were 14 males and 5 females with a mean age of (65.7±13.7)years. Their mean dialysis duration was (45.16±38.18)months. Gastrointestinal tumor was the most common tumor type (9/19). Univariate analysis showed that the age of the patients combined with malignant tumors was significantly higher, and the serum prealbumin was significantly lower than those patients without malignant tumors (all P<0.05). Logistic regression analysis showed that age was the independent risk factor of developing cancers after adjusting dialysis age, hemoglobin, albumin and parathyroid hormone ( P<0.05). Conclusions:The incidence of malignant tumor is significantly higher in maintenance hemodialysis patients than that in the general population. Age is the risk independent risk factor. Therefore, we should strengthen the monitoring of elderly hemodialysis patients, discover the disease in time, and take measures to improve the prognosis.

Objective:To investigate the prevalence of chronic constipation in maintenance hemodialysis (MHD) patients and analyze the risk factors of chronic constipation.Methods:Using the cross-sectional survey method, patients who received MHD in Huadu District People′s Hospital of Guangzhou from September 1, 2021 to September 30, 2021 were enrolled as the research objects. The patient′s demographic, general data and laboratory results were collected. The anxiety level and quality of life were assessed by questionnaires. The patients were divided into constipation group and non-constipation group according to whether they had chronic constipation. The Rome Ⅳ criteria was used to diagnose chronic constipation, and the differences of clinical data between the constipation group and the non-constipation group were compared. The risk factors of chronic constipation in MHD patients were analyzed by logistic regression analysis method.Results:A total of 321 MHD patients were enrolled in this study, with 168 males, 153 females and age of (59.5±13.4) years old (ranged from 29 to 87 years old). There were 160 patients (49.8%) with chronic constipation. The proportions of males, long dialysis age, taking sevelamer and lanthanum carbonate, diabetic nephropathy, and diabetes in the constipation group were higher than those in the non-constipation group, and the differences between the two groups were statistically significant (all P<0.05). The serum calcium, serum phosphorus, calcium-phosphorus product, anxiety scores, average weekly ultrafiltration volume/dry weight in the constipation group were significantly higher than those in the non-constipation group (all P<0.05), and the serum albumin, serum magnesium, urea clearance index (Kt/V) and geriatric nutritional risk index were significantly lower than those in the non-constipation group (all P<0.05). The results of logistic regression analysis showed that moderate to severe anxiety (moderate, OR=3.233, 95% CI 1.339-7.805, P=0.009; severe, OR=5.103, 95% CI 1.906-13.663, P=0.001), existed risk of nutrition (low risk, OR=3.705, 95% CI 1.440-9.533, P=0.007; moderate risk, OR=5.638, 95% CI 2.557-12.430, P<0.001; severe risk, OR=15.097, 95% CI 4.112-55.436, P<0.001), >60 years old (≤40 years old as a reference, OR=4.050, 95% CI 1.366-12.006, P=0.012), diabetes history ( OR=2.224, 95% CI 1.253-3.946, P=0.006), taking sevelamer ( OR=2.290, 95% CI 1.207-4.346, P=0.011), and calcium-phosphorus product ( OR=1.704, 95% CI 1.329-2.186, P<0.001), intact parathyroid hormone ( OR=1.013, 95% CI 1.003-1.022, P=0.007), blood urea nitrogen ( OR=1.092, 95% CI 1.002-1.189, P=0.045) and serum magnesium ( OR=0.042, 95% CI 0.006-0.294, P=0.001) were the independent influencing factors for chronic constipation in MHD patients. Conclusions:The prevalence of chronic constipation in MHD patients is 49.8%. Adequate dialysis, improving calcium and phosphorus metabolism, improving nutritional status, relieving anxiety, and increasing serum magnesium level may help to reduce the risk of chronic constipation in MHD patients.

Objective To investigated the protective effect and immunology mechanism of Astragaloside Ⅳ(Ast) on rat renal ischemia-reperfusion injury model. Methods The SD rats were randomly divided into four group as the control, sham-operation, renal ischemia-reperfusion injury, and Ast treatment groups. Rat serum and urine were collected and detective for kidney function and interleukin cytokines. The kidney tissue was collected for histology exam. The rats in astragaloside group were intraperitoneally injected with 100 mg/kg astragaloside, and the other three groups were intraperitoneally injected with an equal volume of normal saline. The models of renal ischemia-reperfusion injury were prepared to generate in model and astragaloside groups, after 30 minutes of astragaloside injection. The rats with renal ischemia-reperfusion injury model were sacrificed after 24 hours, and the level of blood-urine creatinine, neutrophil gelatinase-associated lipocalin and Kidney damage molecule-1 were determined. The level of Th1 type cytokines (TNF-α, IFN-γ, IL-2) and Th2 type cytokines (IL-4, IL-5, IL-10) in serum were measured by using ELISA. The protein and gene expression of TNF-α, IFN-γ, IL-2, IL-4, IL-5, IL-10 in renal tissue were tested by western blot and PCR, respectively. The pathological changes and apoptosis of renal tissue in each group were detected by HE staining and TUNEL staining, respectively. The expression of CD20 protein in renal tissue was determined by immunohistochemistry. Results Compared with the model group, Ast treatment reduced serum creatinine (58.74 ± 9.44 μmol/L vs. 85.03 ± 23.48 μmol/L), increased creatinine clearance rate (0.81 ± 0.13 ml/min vs. 0.37 ± 0.08 ml/min), and reduce urine neutrophil gelatinase-associated lipocalin (NGAL) (579.34 ± 11.70 pg/ml vs. 827.60 ± 14.48 pg/ml), kidney injury molecule-1 (KIM-1) (105.06 ± 2.10 pg/ml vs. 151.67 ± 3.06 pg/ml) (P<0.05). Compared with the model group, Ast treatment alleviated renal tubular epithelial cell injury and significantly decreased the apoptosis (14.36 ± 1.36% vs. 28.63 ± 2.03%) (P<0.05), and significantly decreased the serum TNF-α (361.44 ± 9.66 pg/ml vs. 515.93 ± 10.61 pg/ml), IFN-γ (64.11 ± 1.21 pg/ml vs. 93.51 ± 2.15 pg/ml), IL-2 (388.33 ± 1.21 pg/ml vs. 557.82 ± 15.29 pg/ml), IL-4 (60.89 ± 1.21 pg/ml vs. 95.56 ± 2.75 pg/ml), IL-5 (94.02 ± 2.81 pg/ml vs. 147.07 ± 3.50 pg/ml), and IL-10 (52.62 ± 2.51 pg/ml vs. 78.22 ± 3.24 pg/ml) (P<0.01). Compared with the model group, Ast treatment significantly decreased the kidney TNF-α mRNA (1.89 ± 0.59 vs. 2.87 ± 0.97), IFN-γ mRNA (3.11 ± 1.02 vs. 5.98 ± 1.52), IL-2 mRNA (1.68 ± 0.44 vs. 4.09 ± 1.65), IL-4 mRNA (2.41 ± 0.81 vs. 4.69 ± 1.62), IL-5 mRNA (1.56 ± 0.19 vs. 2.92 ± 0.55), IL-10 mRNA (1.45 ± 0.14 vs. 2.85 ± 0.32) (P<0.01). The ratio of IL-4 to IFN-γ was basically restored to the level of sham operation group (1.05 ± 0.02 vs. 1.02 ± 0.06) (P<0.01), and CD20 cells in renal tissue was reduced. Conclusions The Th1 and B lymphocytes play an important role in renal ischemia reperfusion injury, and Th2 cells play a protective role. Astragaloside can regulate the imbalance of Th1/Th2 in the early stage after acute renal injury, and alleviate renal tubular injury.
