ABSTRACT
Objective To analyze the relationship between the expression levels of pyruvate dehydro-genase kinase 1(PDK 1)and Ki-67 with the survival and prognosis of the patients with ovarian serous carci-noma(OSC).Methods The cancer tissues of 93 patients with OSC treated by surgery in this hospital from January 2000 to June 2020 were collected,and the expression levels of PDK1 and Ki-67 in the tissues were de-tected by immunohistochemistry.The relationship between the expression levels of PDK1 and Ki-67 with the clinicopathological characteristics of the patients with OSC was analyzed by the single factor and binary logis-tic regression model.The relationship between the PDK1 and Ki-67 expression levels with the recurrence and platinum resistance within 3 years was analyzed.The Kaplan-Meier survival curve was adopted to analyze the effect of PDKI and Ki-67 expression levels on the survival and prognosis in the patients with OSC.Results The expression levels of PDK1 and Ki-67 were related with the International Federation of Gynecology and Obstetrics(FIGO)stage,tissue differentiation level,lymphatic metastasis,ascites formation and positive asci-tes(P＜0.05).The high expression of PDK1 was a risk factor for the late FIGO stage(Ⅲ-Ⅳ),lymphatic metastasis and ascites positive in the patients with OSC(P＜0.05);the high expression of Ki-67 was a risk factor for the late FIGO stage(Ⅲ-Ⅳ)and ascites formationin in the patients with OSC(P＜0.05).The re-currence rate and platinum resistance rate within 3 years in the patients with PDKi and Ki-67 high expressions were significantly higher than those in the patients with low expressions(P＜0.05).The progression-free survival(PFS),overall survival(OS)and 5-year survival rate in the patients with high PDK1 and Ki-67 ex-pressions were significantly lower than those in the patients with low expressions(P＜0.05).Conclusion The expression levels of PDK 1 and Ki-67 play an important role in judging the survival and prognosis of the patients with OSC.
ABSTRACT
Hematuria is the presence of blood in the urine and is classified as either gross hematuria or microscopic hematuria. There are many causes of hematuria, and the differential diagnosis depends on the presence or absence of comorbidities and whether it is glomerular or non-glomerular. When hematuria in children is symptomatic or persistent, an evaluation of the cause is essential. The causes of hematuria and basic approaches to its diagnosis are discussed in this review.
ABSTRACT
Purpose@#This study aimed to evaluate the effectiveness of exercise in patients with hemophilia. @*Methods@#We carried out a systematic review and meta-analysis in accordance with the Preferred Reporting Items for Systematic Review and Meta-analysis guidelines. A literature search was conducted of published randomized controlled trials for exercise interventions from January 1, 2014 to March 15, 2023. To estimate the size of the effects of exercise, a meta-analysis was performed using the R package “meta.” @*Results@#Five databases were searched to obtain articles published in Korean or English. Of 1,150 articles reviewed, 13 were included in the systematic review and 9 in the meta-analysis. The risk of bias was assessed using RoB 2.0. Results: The overall effect sizes of exercise interventions, calculated as the standardized mean difference, were -0.11 (95% confidence interval [CI] = -1.41 to –1.20) for pain, -2.13 (95% CI = -3.33 to -0.93) for joint health, 9.96 (95% CI = 7.51 to 12.28) for physical activity, and 0.59 (95% CI = -0.39 to -1.56) for quality of life. @*Conclusion@#These findings suggest that exercise is useful for improving the joint health and physical activity of patients with hemophilia. Thus, it is necessary to develop and apply exercise interventions for patients with hemophilia to reduce their pain and improve their quality of life.
ABSTRACT
Objectives@#Severe mental illness has become one of the leading concerns for the cost of health services. This study analyzed the demographic characteristics and compared the patterns of medical health service use according to the diagnosis of severe mental illness, including schizophrenia spectrum disease, bipolar disease, and major depressive disorder. @*Methods@#The data from the National Health Insurance Corporation were analyzed, selecting subjects diagnosed at least once for severe mental illness between 2014 and 2019. Severe mental illness included the following: schizophrenia, schizotypal, and delusional disorders (F20– 29); manic episodes and bipolar affective disorder (F30–31); and moderate depressive episodes with psychotic features and recurrent depressive disorder (F32.3–F33). The demographic factors and patterns of medical services, such as outpatient, hospitalization, and re-admission differences, were compared according to the diagnostic categories. @*Results@#This study included 842459 patients, with 39.6% people in F20–F29, 33.7% in F32.3– F33, and 26.8% in the F30–F31 category. There were significant differences in gender, age, insurance type, Charlson Comorbidity Index score, and economic level according to the diagnostic categories. The engagement of medical health services also showed significant differences among the diagnostic categories. F32.3–F33 showed higher engagement of outpatients than the out-groups, while F20–F29 showed a higher admission rate. The hospitalization duration was significantly longer in F20–F29, and the re-admission rate after discharge within one year was significantly higher in the same group. @*Conclusion@#This paper reviewed the differences in medical care utilization among severe mental illness. The result emphasizes the need for a mental health care system broadening to the community, facilitating psychosocial intervention, and case management.
ABSTRACT
Objective@#The purpose of this study was to identify the associations of chronic physical disease between patients with severe mental illness (SMI) and the general population of South Korea. @*Methods@#This study was conducted with National Health Insurance Corporation data from 2014 to 2019. A total of 848,058 people were diagnosed with SMI in this period, and the same number of controls were established by matching by sex and age. A descriptive analysis was conducted on the sociodemographic characteristics of patients with SMI. Conditional logistic regression analysis was performed to identify the associations between comorbid physical disease in patients with SMI and those of the general population. SAS Enterprise Guide 7.1 (SAS Inc, Cary, NC, USA) were used to perform all statistical tests. @*Results@#The analysis revealed significant differences in medical insurance, income level, and Charlson Comorbidity Index weighted by chronic physical disease, between patients with SMI and the general population. Conditional logistic regression analysis between the two groups also revealed significant differences in eight chronic physical diseases except hypertensive disease. @*Conclusion@#This study confirmed the vulnerability of patients with SMI to chronic physical diseases and we were able to identify chronic physical disease that were highly related to patients with SMI.
ABSTRACT
Background/Aims@#Sensitization to staphylococcal superantigens (SAgs) could contribute to asthma severity. However, its relevance with eosinophilic phenotype has not yet been clarified. This study aimed to investigate associations between serum specific IgE levels to SAg and eosinophilic airway inflammation in adult asthmatics. @*Methods@#The serum specific IgE levels to 3 SAgs, including staphylococcal enterotoxin A (SEA) and B (SEB), and toxic shock syndrome toxin-1 (TSST-1) were measured by ImmunoCAP in 230 adult asthmatic patients and 50 healthy controls (HCs). Clinical characteristics and laboratory parameters, including serum total/free IgE, and 2 eosinophil-activation markers, eosinophil cationic protein (ECP), and eosinophil-derived neurotoxin (EDN), were analyzed according to blood eosinophil counts (BEC; 150 cells/μL) and serum specific IgE levels to 3 SAgs (0.35 kU/L). @*Results@#Asthmatic patients showed higher serum specific IgE levels to 3 SAgs than HCs (p < 0.05 for all). The serum total/clinfree IgE levels were significantly higher in asthmatics with positive IgE responses to 3 SAgs than those without (p < 0.05 for all). There were no significant differences in clinical parameters including age, asthma severity, comorbidities, or smoking according to IgE responses to 3 SAgs. Patients with positive IgE responses to SEB (not to SEA/TSST-1) had higher serum specific IgE levels to house dust mites and ECP/EDN as well as higher BEC with positive correlations between serum SEB-specific IgE levels and BEC/ECP/EDN (p < 0.05 for all). @*Conclusions@#These findings suggest that serum SEB-specific IgE levels could contribute to eosinophil activation as well as IgE production in adult asthma.
ABSTRACT
Dent disease is a rare inherited kidney tubulopathy caused by mutations in either the CLCN5 (Dent disease 1) or OCRL1 (Dent disease 2) genes, and which is often underdiagnosed in practice. A diagnosis is clinically suspected in patients with low-molecular-weight proteinuria, hypercalciuria, and one of the following: hematuria, nephrolithiasis, nephrocalcinosis, hypophosphatemia, or chronic kidney disease. Inheritance is X-linked recessive, meaning, these symptoms are generally only found in males; female carriers may have mild phenotypes. Genetic testing is only a method to confirm the diagnosis, approximately 25% to 35% of patients have neither the CLCN5 nor OCRL1 pathogenic variants (Dent disease 3), making diagnosis more challenging. The genotype-phenotype correlations are not evident with the limited clinical data available. As with many other genetic diseases, the management of patients with Dent disease concentrates on symptom relief rather than any causative process. The current treatments are mainly supportive to reduce hypercalciuria and prevent nephrolithiasis. Chronic kidney disease progresses to end-stage between the ages of the third to fifth decades in 30% to 80% of affected males. In this review, we aimed to summarize the literature on Dent disease and reveal the clinical characteristics and molecular basis of Korean patients with Dent disease.
ABSTRACT
Purpose@#Angiotensin-converting enzyme inhibitors and angiotensin II receptor blockers (ARBs) are frequently employed to counteract the detrimental effects of proteinuria on glomerular diseases. However, the effects of ARBs remain poorly examined in pediatric patients with immunoglobulin A (IgA) nephropathy. Herein, we evaluated the efficacy and safety of losartan, an ARB, in pediatric IgA nephropathy with proteinuria. @*Methods@#This prospective, single-arm, multicenter study included children with IgA nephropathy exhibiting proteinuria. Changes in proteinuria, blood pressure, and kidney function were prospectively evaluated before and 4 and 24 weeks after losartan administration. The primary endpoint was the difference in proteinuria between baseline and 24 weeks. @*Results@#In total, 29 patients were enrolled and received losartan treatment. The full analysis set included 28 patients who received losartan at least once and had pre- and post-urinary protein to creatinine ratio measurements (n=28). The per-protocol analysis group included 22 patients who completed all scheduled visits without any serious violations during the study period. In both groups, the mean log (urine protein to creatinine ratio) value decreased significantly at 6 months. After 24 weeks, the urinary protein to creatinine ratio decreased by more than 50% in approximately 40% of the patients. The glomerular filtration rate was not significantly altered during the observation period. @*Conclusions@#Losartan decreased proteinuria without decreasing kidney function in patients with IgA nephropathy over 24 weeks. Losartan could be safely employed to reduce proteinuria in this patient population. ClinicalTrials.gov trial registration (NCT0223277)
ABSTRACT
Purpose@#This study aimed to update the previously published nursing practice guideline for prevention of venous thromboembolism (VTE). @*Methods@#The guideline was updated according to the manuals developed by National Institute for Health and Care Excellence (NICE) and Scottish Intercollegiate Guidelines Network (SIGN), and a Handbook for Clinical Practice Guideline Developer Version 10. @*Results@#The updated nursing practice guideline for prevention of VTE was consisted of 16 domains, 46 subdomains, and 216 recommendations. The recommendations in each domain were: 4 general issues, 8 assessment of risk and bleeding factors, 5 interventions for prevention of VTE, 18 mechanical interventions, 36 pharmacological interventions, 36 VTE prevention starategies for medical patients, 25 for cancer patients, 13 for pregnancy, 8 for surgical patients, 7 for thoractic and cardiac surgery, 16 for orthopedic surgery, 10 for cranial and spinal surgery, 5 for vascular surgery, 13 for other surgery, 3 educations and information, and 2 documentation and report. For these recommendations, the level of evidence was 32.1% for level I, 51.8% for level II, and 16.1% for level III according to the infectious diseases society of America (IDSA) rating system. A total of 112 new recommendations were developed and 49 previous recommendations were deleted. @*Conclusion@#The updated nursing practice guideline for prevention of VTE is expected to serve as an evidence-based practice guideline for prevention of VTE in South Korea. It is recommended that this guideline will disseminate to clinical nursing settings nationwide to improve the effectiveness of prevention of VTE practice.
ABSTRACT
Although multiple factors influence the risk of major adverse cardiovascular events (MACE), the effects of socioeconomic status on MACE in the presence and absence of renal dysfunction (RD) have not been comprehensively explored in Korea. Methods: We examined the effects of socioeconomic status on MACE in individuals with and without RD. The data of 44,473 Koreans from 2008 to 2017 were obtained from the Health Care Big Data Platform of the Ministry of Health and Welfare in Korea. Their socioeconomic status was assessed using a socioeconomic score (SES) based on marital status, education, household income, and occupation. The incidence of myocardial infarction (MI), stroke, and death was compared according to SES level (0–4). Multiple linear regression analysis was used to evaluate the hazard ratios and 95% confidence intervals for outcomes based on participant SES. Results: MI risk was only affected by education level. The participants’ income, education, and SES affected their stroke risk, whereas death was associated with all four socioeconomic factors. The incidence of stroke and death increased as SES worsened (from 0 to 4). SES was positively related to risk of stroke and death in participants without RD. SES did not affect MI, stroke, or death in participants with RD. Conclusion: A low socioeconomic status is associated with risk of stroke and death, especially in individuals without RD.
ABSTRACT
Background@#Using path analysis, we aimed to examine whether parenting self-efficacy and parenting styles would be significant associates with parenting behavior, and the parenting behavior would be significantly associated with the obesity status of children from socioeconomically vulnerable families. @*Methods@#A cross-sectional study was conducted with 61 parents and their children enrolled in public welfare systems in a community in Seoul, South Korea. Parenting behavior was defined as encouraging a child’s healthy eating habits and was measured using the Child Feeding Questionnaire. @*Results@#In the path model, higher levels of parenting self-efficacy and lower levels of authoritarian parenting were significantly associated with a higher level of parenting behavior, which was significantly associated with lower child body mass index z-scores. @*Conclusions@#Community health nurses need to provide intervention strategies for increasing parenting self-efficacy and decreasing authoritarian parenting styles to promote parenting behaviors and childhood obesity prevention among socioeconomically vulnerable families.
ABSTRACT
Background@#Transient receptor potential canonical (TRPC) channels are non-selective cationic channels with perme‑ ability to Ca2+ and Na+ . Despite their importance, there are currently few studies on TRPC in the periodontal ligament (PDL) and bone cells in the dental field. To provide biological information regarding TRPC in PDL cells and periodontal tissue, we evaluated TRPC channels expression in the osteoblast differentiation of PDL cells and periodontitis-induced tissue. Human PDL cells were cultured in osteogenic differentiation media for 28 days, and the expression of Runx2, osteocalcin (OCN), and TRPC1, 3, 4, and 6 was evaluated by real-time PCR. In ligature-induced periodontitis mice, the alveolar bone and osteoid areas, the osteoclast number, and the expression of Runx2, OCN, TRPC3, and TRPC6 was evaluated by H&E staining, TRAP staining, and immunohistochemistry, respectively. @*Results@#In the PDL cell differentiation group, TRPC6 expression peaked on day 7 and TRPC3 expression generally increased during differentiation. During the 28 days of periodontitis progression, alveolar bone loss and osteoclast numbers increased compared to the control group during the experimental period and the osteoid area increased from day 14. TRPC6 expression in the periodontitis group increased in the PDL area and in the osteoblasts compared to the control group, whereas TRPC3 expression increased only in the PDL area on days 7 and 28. @*Conclusions@#These results indicate changes of TRPC3 and TRPC6 expression in PDL cells that were differentiating into osteoblasts and in periodontitis-induced tissue, suggesting the need for research on the role of TRPC in osteo‑ blast differentiation or periodontitis progression.
ABSTRACT
Cerebral small vessel disease (CSVD) is the most common cerebrovascular disease in the elderly, which is closely related to ischemic stroke and cognitive impairment. Early neuroimaging assessment of CSVD is of great clinical significance. With the development of medical imaging technology, it has gradually developed from visual rating assessments to quantitative volumetric assessments; therefore, it can evaluate the severity of CSVD reasonably and efficiently. This review focuses on application of some quantitative neuroimaging assessment techniques in CSVD, in order to provide new evaluation methods and ideas for clinical and basic research of CSVD.
ABSTRACT
Objective:To identify the influencing factors for cognitive impairment in patients with recent small subcortical infarct (RSSI), and explore the relationship between enlarged perivascular space (EPVS) and executive function in patients with RSSI.Methods:From February to December 2021, 115 patients with RSSI accepted treatment in Department of Neurology, Changzhou Second People's Hospital Affiliated to Nanjing Medical University were enrolled. According to Montreal cognitive assessment (MoCA) scores, these patients were divided into normal cognitive function group (MoCA scores≥26, n=45) and cognitive impairment group (MoCA scores<26, n=70); univariate analysis was used to analyze the differences of general clinical data and EPVS volume between the two groups; multivariate Logistic regression analysis was used to identify the independent influencing factors for RSSI combined with cognitive impairment. Patients were further divided into EPVS non-mild group and EPVS moderate-severe group according to EPVS visual assessment; the differences of scores of different executive function domains were compared between the two groups; Spearman correlation analysis was used to observe the relationships of EPVS grading and volume with executive function. Results:Patients in the cognitive impairment group had significantly older age, significantly higher serum creatinine level, proportion of patients with moderate-severe basal ganglia EPVS (BG-EPVS) and BG-EPVS volume, and significantly lower years of education as compared with those in the normal cognitive function group ( P<0.05). Multivariate Logistic regression analysis showed that BG-EPVS volume ( OR=1.421, 95%CI: 1.028-1.965, P=0.034) was an independent risk factor for RSSI combined with cognitive impairment. MoCA total scores, scores of visual space and executive function domains in patients of the BG-EPVS moderate-severe group were significantly lower than those in patients of the BG-EPVS non-mild group, while Z-scores of Stroop color word test (SCWT) and trail making test (TMT), and total Z-scores of executive function were significantly higher than those in patients of the BG-EPVS non-mild group ( P<0.05). Spearman correlation analysis showed that BG-EPVS grading and volume were positively correlated with total Z-scores of executive function in RSSI patients with cognitive impairment ( r=0.439, P=0.001; r=0.410, P=0.001). Conclusion:BG-EPVS volume is an independent risk factor for cognitive impairment, and both BG-EPVS grading and volume are correlated with impairment degrees of executive function in cognitive function in RSSI patients.
ABSTRACT
Microglia differ from macrophages with unique origin and role. In glioblastoma, microglia plays an important role in regulating tumor immune status, promoting tumor angiogenesis, destroying the blood-brain barrier, and reducing the sensitivity of treatment. Therefore, the combination of microglial therapy in the radiotherapy, chemotherapy and immunotherapy of glioblastoma has also become a clinically promising treatment.
ABSTRACT
Objective@#This study analyzed the relationship between sociodemographics and health behaviors that affect depression and stress of the aged 65 or older living in Seoul in 2018. @*Methods@#The subjects were selected according to the purpose by receiving raw data from the Korea Centers for Disease Control and Prevention, and 5,753 respondents were analyzed. @*Results@#In depression, the demographic and sociological factors with differences were sex, marriage, single-person household,current basic living, economic activity and monthly income, and the health behaviors with significant differences were past smoking, diabetes and insufficient annual medical use. In the stress level, the demographic and sociological factors with differences were age, sex, current basic living, monthly income and education, and the health behaviors with significant differences were current/past smoking, diabetes and insufficient annual medical use. The factors affecting depression and stress were not completely consistent but similar, and both had low rates of expert counseling. @*Conclusion@#This study is meaningful in that it identified the factors affecting the depression and stress of the elderly especially in Seoul, the metropolitan city. If future research reveals additional factors, it will be helpful to suggest the direction of government policy and contribute to improving the quality of life of the elderly in the super-aged era.
ABSTRACT
Objective:To compare the detection success rates (DSRs) of different kinds of near-infrared spectrum non-invasive hemoglobin monitors in high-altitude environments.Methods:One hundred and forty-four healthy volunteers of either sex, aged 18-50 yr, were assigned to one of 3 groups using a random number table method: simulated high-altitude 3 500 meter group ( n=35), 4 000 meter group ( n=55) and 4 500 meter group ( n=54). Hemoglobin was detected by Radical-7, NW-9002SHM, A5 and TensorTip MTX type hemoglobin monitors in plain environment and simulated environment at different altitudes, and the DSRs were compared.Logistic regression analysis was conducted to identify the risk factors affecting the success rate of instrument detection, and the cut-off value was determined by ROC curve and the Youden index. Results:In the simulated high-altitude environment of 3500, 4000 and 4500 m, the DSR of TensorTip MTX was significantly higher than that of Radical-7, NW-9002SHM and A5 ( P<0.001), and there was no significant difference in the DSR among Radical-7, NW-9002SHM and A5 ( P>0.05). Low SpO 2 was the main factor affecting the DSRs of the Radical-7, NW-9002SHM and A5 type hemoglobin monitor in high-altitude environment ( P<0.001), and the cut-off value of SpO 2 in determining the success of detection was 88.5%, 87.5% and 89.5%, respectively.The DSR of TensorTip MTX was not affected by low SpO 2. Conclusions:The DSR of TensorTip MTX hemoglobin monitor is minimally affected by the high-altitude environment and can be preferred in the absence of oxygen supply; when Radical-7, NW-9002SHM or A5 hemoglobin monitor applied in high-altitude environments, oxygen saturation needs to be increased to ensure a high DSR.
ABSTRACT
End-stage renal disease (ESRD) patients on hemodialysis have poor nutritional status and associated problems such as inflammation and sarcopenia. Blood urea nitrogen (BUN) is an important measure of uremic toxins, and urea reduction is a marker of hemodialysis efficacy. However, a low protein diet for lower BUN could aggravate malnutrition in patients, and optimal pre-dialysis BUN is not defined. We investigated the association of pre-dialysis BUN with patients’ comorbidities and the relationship between pre-dialysis BUN and serum albumin as a nutrient marker. Among the 67 patients, the average pre- and post-dialysis BUN were 59.2 and 15.0 mg/dL, respectively, serum creatinine was 10.1 mg/dL, and the average serum albumin was 4.0 g/dL. Patients’ age was negatively correlated with serum creatinine (r=−0.277, p<0.05) and albumin (r=−0.453, p<0.001). Predialysis BUN showed a significant positive correlation with serum albumin (r=0.287, p<0.05) and creatinine (r=0.454, p<0.001). However, the predialysis BUN was not significantly related to diabetes, coronary artery disease, congestive heart failure, or cerebrovascular disease. Hemodialysis patients with high pre-dialysis BUN and high serum creatinine could be regarded as having good nutritional status. The significance of this study lies in the potential utility of pre-dialysis blood urea nitrogen as an indicator of the nutritional status of patients. Liberal protein intake might be recommended to adequately dialyzed patients.
ABSTRACT
Background/Aims@#The obesity paradox has been known in end-stage renal disease (ESRD). However, the effect of body mass index (BMI) or waist circumference (WC) prior to percutaneous coronary intervention (PCI) on the development of ESRD is not clear. @*Methods@#Using nationally representative data from the Korean National Health Insurance System, we enrolled 140,164 subjects without ESRD at enrolment who underwent PCI between 2010 and 2015, and were followed-up until 2017. Patients were stratified into five levels based on their baseline BMI and six levels based on their WC with 5-cm increments. BMI and WC were measured at least 2 years prior to PCI. The primary outcome was the development of ESRD. @*Results@#During a median follow-up of 5.4 years, 2,082 (1.49%) participants developed ESRD. The underweight group (hazard ratio [HR], 1.331; 95% confidence interval [CI], 0.955 to 1.856) and low WC (< 80/< 75) (HR, 1.589; 95% CI, 1.379 to 1.831) showed the highest ESRD risk and the BMI 25 to 30 group showed the lowest ESRD risk (HR, 0.604; 95% CI, 0542 to 0.673) in all participants after adjusting for all covariates. In the subgroup analysis for diabetes mellitus (DM) duration, WC < 85/80 cm (men/women) increased ESRD risk in only the DM group (DM < 5 years and DM ≥ 5 years) compared to the reference group (85–90/80–85 of WC), but not the normal or impaired fasting glucose group. @*Conclusions@#Low WC prior to PCI showed an increased ESRD risk in patients with DM undergoing PCI as compared to those without DM.
ABSTRACT
ObjectiveTo discuss the effect of forgetting curve based self-management on cognitive function， daily living ability and treatment efficacy of patients with mild cognitive impairment （MCI）. MethodsSimple random sampling method was adopted to enroll 162 MCI patients who met the diagnostic criteria of "Expert Consensus on the Prevention and Treatment of Cognitive Impairment in China" in Nanchong Physical and Mental Hospital and Gaoping Ledele Seniors-Oriented Apartment from April 2020 to June 2021. The selected individuals were classified into study group and control group according to random number table methods， each with 81 cases. Both groups received routine intervention， based on this， study group received the forgetting curve based self-management. The interventions lasted for 3 months in two groups， and patients were assessed using Montreal Cognitive Assessment Scale （MoCA） and Activity of Daily Living Scale （ADL） at the baseline and end of interventions. Then the clinical efficacy was compared between groups. ResultsAfter intervention， an increase was found in MoCA and ADL scores in both groups （tcontrol group=25.004， 12.503， tstudy group=48.211， 24.949， P<0.01）， and post-intervention MoCA and ADL scores in study group were higher than those in control group （t=28.527， 9.433， P<0.01）. The overall efficacy rate was 86.42% in control group， which was lower than 96.30% in study group， with statistical difference （χ²=5.004， P<0.05）. ConclusionForgetting curve based self-management may ameliorate the cognitive function and daily living ability in MCI patients， thus improving the treatment efficacy.
