Methods:One hundred and ninety hypertensive patients from January 2008 to November 2008 in West China Hospital of Si Chuan University. We collected the general data and applied the Mini Mental State Examination to test the cognitive function and computed score. PCRRELP method was used to analyze the LPL S447X gene polymorphism. Total cholesterol、triglyeride、fasting plasma glucose and postprandial blood sugar、fasting insulin and postprandial plasma insulin were collected. Results:In primary hypertensive patients, both of the genotype frequency and the allele frequency of the LPL S447X polymorphism were not different between the cognitive normal group and the cognitive impaired group (Pgt;0.05). SS genotype was present in 0926 of the population, SX genotype was present in 0.074 of the population. allele frequencies were 0.963 for S allele and 0.037 for X allele. Conclusion:This results suggest S447X polymorphism in LPL with primary hypertension may not be associated with cognitive impairment. And age and postprandial plasma insulin level are the risk factors of hypertensive cognitive impairment.

Congenital heart disease (CHD) is a series of structural cardiac abnormalities resulting from abnormal fetal heart development. With the prolongation of survival time, their cognitive function problems begin to be concerned. From fetus period to adulthood, people with complex CHD are more likely to have abnormalities in brains. Children with complex CHD have a significantly increased risk of developmental disorders in cognitive functions, such as intelligence, attention and psychosocial disorders. These diseases persist into their adulthood. Adults with CHD have earlier neurocognitive decline, poorer performance in intelligence, executive function, attention and academic achievement, and are more likely to have mood disorders, higher incidence of mental disorders and lower quality of life. This paper reviews the studies on cognitive function of adult patients with CHD from the dimension of the whole life cycle.
Objective To investigate the effects of children’s crawling-promotion-training-robot on gross motor function and cognitive function in children with global developmental delay (GDD). Methods A total of 40 children with GDD admitted to the Department of Rehabilitation Medicine, Children’s Hospital of Nanjing Medical University were selected as the research subjects. By envelope method, the children were randomly and equally divided into experimental group and control group, with 20 cases in each group. The experimental group received children’s crawling-promotion-training-robot combined with conventional rehabilitation therapy, while the control group received manual crawling training combined with conventional rehabilitation therapy. Before and after treatment, the scores of Gross Motor Function Measure Scale-88 (GMFM-88) and Gesell Developmental Scale (GDS) were respectively used to evaluate gross motor function and cognitive function. Results There was no significant difference in gender (χ2=0.100, P=0.752) and age (t=0.053, P=0.962) between the two groups. Before treatment, there was no significant difference in GMFM-88 and GDS scores between the two groups (P>0.05). After treatment, there were statistically significant differences in GMFM-88 and GDS scores between the two groups (P<0.05). The comparison within the group showed that there were statistically significant differences in GMFM-88 and GDS scores between the two groups before and after treatment. Conclusion Children’s crawling-promotion-training-robot is more effective than manual crawling training in improving gross motor function and cognitive function in children with GDD.
Objective To explore the correlation between the levels of serum nuclear factor-erythroid 2-related factor 2 (Nrf2) as well as heme oxygenase-1 (HO-1) and cognitive dysfunction by determining the levels of Nrf2 and HO-1 in patients with obstructive sleep apnea (OSA) to different degrees and combining Montreal cognitive assessment (MoCA). Methods Serum levels of Nrf2 and HO-1 were determined in 32 patients with mild-moderate OSA, 23 patients with severe OSA and 20 healthy controls. The differences of Nrf2 and HO-1 levels among groups were compared. All subjects were evaluated by MoCA score. According to MoCA score, OSA patients were divided into two groups: OSA with mild cognitive impairment (MCI) group and OSA with normal cognition group. Serum Nrf2 and HO-1 levels were compared between the two groups, and the differences in the OSA patients with or without cognitive impairment were understood. Spearman correlation coefficient was used to explore the correlation between serum Nrf2 and HO-1 levels and cognitive function of OSA patients. The diagnostic value of serum Nrf2 and HO-1 in the OSA patients with cognitive impairment was determined by receiver operating characteristic curve. Results Serum levels of Nrf2 and HO-1 in the mild-moderate and severe OSA groups were higher than those in the control group, and those in the severe OSA group were higher than those in the mild-moderate OSA group (P<0.05). Compared with the OSA with normal cognition group, the serum HO-1 level in the OSA patients with MCI was higher (P<0.05), but the serum NRF2 level had no significant difference between the two groups (P>0.05). There was a negative correlation between serum HO-1 level and total MoCA score in the OSA patients (r=–0.495, P=0.000), but there was no significant correlation between serum Nrf2 and total MoCA score in the OSA patients (P>0.05). Serum Nrf2 and HO-1 were 0.791 and 0.818 for predicting OSA patients with cognitive impairment. The sensitivity was 84.20% and 86.80%, and the specificity was 67.60% and 73.00%, respectively. Conclusions Serum Nrf-2 and serum HO-1 play important role in the pathogenesis of OSA. Serum HO-1 level may be closely related to cognitive dysfunction in OSA patients. Detection of serum HO-1 may be helpful in early identification of cognitive dysfunction in OSA patients, which has potential clinical application value.
Objective To analyze the efficacy of music therapy on the rehabilitation of post-stroke cognitive impairment (PSCI) and to provide a reference for rehabilitation intervention methods for PSCI. Methods Patients hospitalized in Beijing Bo’Ai Hospital, China Rehabilitation Research Center and diagnosed with PSCI between December 2020 and July 2022 were prospectively selected. According to the random number table method, patients were divided into a music therapy group and a control group. Both groups were given conventional neurology medication, nursing care, and conventional rehabilitation. The music therapy group received additional music therapy training, and both groups received treatment for one month. The Montreal Cognitive Assessment (MoCA), National Institute of Health Stroke Scale (NIHSS), Fugl-Meyer Assessment Scale (FMA), and modified Barthel Index (MBI) were used before and after treatment to assess patients’ cognitive function, degree of neurological deficits, motor function and activities of daily live. Results A total of 48 patients were included, with 24 patients in both groups. There was no statistically significant difference in gender, age, education level, stroke type, lesion location, comorbidities, history of myocardial infarction or peripheral vascular disease, and smoking status between the two groups of patients (P>0.05). Before and after treatment, most patients in the two groups did not score in terms of language and delayed recall scores, and the difference were not statistically significant (P>0.05). There was no statistically significant difference in MoCA scores, visual space and executive function, naming, attention, calculation, abstract thinking, and orientation scores between the two groups of patients before treatment (P>0.05). After treatment, the MoCA score, visual space and executive function, naming, attention, calculation, abstract thinking, and orientation scores of the music therapy group improved compared to before treatment (P<0.05), while the MoCA score, visual space and executive function, naming, attention, and orientation scores of the control group improved compared to before treatment (P<0.05). After treatment, the improvement in MoCA scores [5.0 (3.0, 6.0) vs. 2.5 (1.0, 4.0)], attention [1.0 (0.0, 1.0) vs. 0.0 (0.0, 1.0)], and abstract thinking scores [0.0 (0.0, 1.0) vs. 0.0 (0.0, 0.0)] in the music therapy group were better than that in the control group (P<0.05). There was no statistically significant difference in NIHSS, FMA, and MBI scores between the two groups of patients before treatment (P>0.05), and both groups improved after treatment compared to before treatment (P<0.05). After treatment, there was no statistically significant difference in the improvement of NIHSS, FMA, and MBI scores between the two groups of patients (P>0.05). Conclusions Compared with conventional rehabilitation therapy, training combined with music therapy is more beneficial for improving cognitive function in PSCI patients, especially in the cognitive domains of attention and abstract thinking. However, significant advantages have not been found in improving the degree of neurological impairment, limb motor function, and daily living activities.
Objective To explore the effect of total glucosides of Cistanche deserticola on oxidative stress and cognitive function in rats with intermittent hypoxia. Methods Adult male Wistar rats (n=72) were randomly divided into three groups: a blank control group, a 5% intermittent hypoxia group (IH group) and a total glucosides of Cistanche deserticola intervention group (TGs intervention group). The 5% intermittent hypoxia rat model was simulated by using the self-made cabin of intermittent hypoxia. The rats in the IH group and the TGs intervention group were given 5% intermittent hypoxia respectively, and the rats in the TGs intervention group were treated with total glucosides of Cistanche deserticola simultaneously. Learning and memory function was tested by Morris water maze in three groups at the 2nd, 4th, 6th and 8th week respectively. The expressions of superoxide dismutase (SOD) and malondialdehyde (MDA) in hippocampus were detected by test kit. Results Compared with the blank control group, the escape latency time of the rats in the IH group and the TGs intervention group was significantly prolonged at the 2nd, 4th, 6th and 8th week respectively (P<0.05). The time to cross the target quadrant in the IH group and the TGs intervention group was gradually shortened at the 2nd, 4th, 6th and 8th week respectively (P<0.05). Compared with the IH group, the escape latency gradually shortened at the 2nd, 4th, 6th and 8th week in the TGs intervention group (P<0.05), while the time to cross the target quadrant was gradually prolonged at the 2nd, 4th, 6th and 8th week (P<0.05). The expressions of MDA in hippocampal tissue in the IH group and the TGs intervention group increased at the 2nd, 4th, 6th and 8th week (P<0.05), which were significantly higher than those in the blank control group; and the expressions of SOD at the 2nd, 4th, 6th, and 8th week were all lower than those in the blank control group(P<0.05). Compared with the IH group, the expression of MDA protein in hippocampal tissue in the TGs intervention group decreased at the 2nd, 4th, 6th and 8th week, while the expression of SOD protein at the 2nd, 4th, 6th and 8th week increased, and the differences were statistically significant (P<0.05). Conclusion The total glycosides of Cistanche deserticola can improve the learning and memory function of intermittent hypoxia rats by inhibiting oxidative stress.
Objective To evaluate the effect of different non-pharmacological interventions on the cognitive function of elderly people with cognitive decline, and provide useful reference for improving cognitive function of the elderly. Methods Computer searches of PubMed, Embase, the Cochrane Library, Web of Science, China National Knowledge Infrastructure, VIP Database, Wanfang Data, and China Biomedical Literature Database for randomized controlled trials on non-pharmacological interventions for aged adults with cognitive decline were conducted, all with a search time frame from database inception to October 9th, 2023. Literature screening, information extraction and bias risk assessment using RevMan 5.4 software were performed by two evaluators independently, and Stata 16.0 and R 4.3.0 software was used for network meta-analysis. Results A total of 27 articles involving 2149 elderly patients and 7 intervention protocols were included. Among the 27 articles, 8 were graded A and 19 were graded B for quality. The network meta-analysis revealed that, using the Montreal Cognitive Assessment (MoCA) as the evaluating metric, virtual reality [mean difference (MD)=6.01, 95% confidence interval (CI) (0.90, 10.75)], cognitive training [MD=4.99, 95%CI (0.56, 9.12)], and exercise training [MD=3.88, 95%CI (0.47, 7.27)] were better than community services, respectively (P<0.05), and exercise training was also better than conventional care [MD=3.05, 95%CI (0.92, 5.12), P<0.05]; using the Mini-Mental State Examination (MMSE) as the evaluation indicator, multimodal exercise [MD=3.00, 95%CI (0.89, 4.96)], cognitive training [MD=2.50, 95%CI (0.27, 4.82)], traditional Chinese exercise [MD=2.30, 95%CI (0.34, 4.28)], psychotherapy [MD=1.76, 95%CI (0.56, 2.96)], and exercise training [MD=1.36, 95%CI (0.18, 2.59)] were better than conventional care, respectively (P<0.05), and multimodal exercise [MD=3.32, 95%CI (0.62, 5.81)], cognitive training [MD=2.82, 95%CI (0.75, 4.90)], and traditional Chinese exercise [MD=2.63, 95%CI (0.08, 5.13)] were also better than community service, respectively (P<0.05). The results of the cumulative probability ranking showed that virtual reality had the highest probability of being the best intervention in terms of improving MoCA metrics (0.863), and multimodal exercise had the highest probability of being the best intervention in terms of improving MMSE metrics (0.868). Conclusion Using MoCA as an evaluation indicator, virtual reality may be the best non-pharmacological intervention; using MMSE as an evaluation indicator, multimodal exercise may be the best non-pharmacological intervention.
