ABSTRACT

Alzheimer's disease (AD) is one of the major diseases that harmful to healthy elderly, and mild cognitive impairment (MCI) is the early clinical stage of AD. There is a lag in the clinical diagnosis of both diseases. An objective and reliable auxiliary diagnostic method is urgently needed to provide early diagnosis and differential indicators for AD and MCI, to predict the probability of individuals suffering from AD and MCI transforming into AD, and to reduce the overall incidence of AD and reduce the huge medical and economic burden for the country and society. Event-related potential is widely used in AD and MCI, and the resolution at the millisecond level can truly reflect the time course of cognitive processing and the degree of impairment of cognitive function in patients. In this study, we investigated the differences in the amplitude and latency of ERP components in healthy elderly, MCI and AD patients, and the correlation between ERP components and cognitive impairment. Early N170 and P200 showed high sensitivity and specificity in differentiating MCI from healthy elderly or MCI from AD. The late perception-related ERPs also showed high sensitivity and specificity in differentiating healthy elderly from MCI/AD. The differences in ERPs between MCI and AD may be related to the etiology, the degree of disease progression and the site of brain damage. The specific brain mechanism still need to be further explored and will be the focus of future research. With the progress of the research, the relationship between the specific ERP manifestations and the mechanism of brain injury as well as the impairment of cognitive function will be more clear. It is believed that the application of ERP in clinical will bring more benefits to AD and its early clinical MCI.

ABSTRACT

Objective:To investigate the relationship between lexical semantic processing abnormalities and cognitive function and clinical symptoms in schizophrenia based on the activation diffusion model and semantic distance.Methods:All subjects matched with demographic data were randomly divided into experiment group( n=27) and control group( n=30). The semantic distance of words of different semantic categories and lexical categories were assigned at a level of 1-7.The semantic distance between the two groups was analyzed by repeated measures of variance, and the correlation analysis was conducted on the scores of the MATRICS Consensus Cognitive Battery (MCCB) and positive and negative syndrome scale (PANSS) in the experimental group. Results:The main effects of the groups in semantic distance were statistically significant( F(1, 55)=7.460, P=0.008, ηp2=0.981). The semantic distance in the experimental group (3.672±0.105)was lower than that in the control group (4.068±0.100). The main effect of the semantic category was statistically significant( F(1, 55)= 833.37, P<0.01, ηp2=0.938), and the semantic distance in the relative condition (1.965±0.074) was lower than that in the unrelative condition(5.775±0.117). Under the relative condition, concrete semantic deviation was negatively correlated with the total score of MCCB( r=-0.405, P=0.036)and speech learning ( r=-0.569, P=0.002). Abstract semantic deviation was negatively correlated with speech learning( r=-0.429, P=0.026). Under the unrelative condition, concrete semantic deviation was negatively correlated with MCCB total score ( r=-0.597, P=0.001), speech learning( r=-0.399, P=0.039)and other dimensions.Abstract semantic deviation was negatively correlated with MCCB total score( r=-0.593, P=0.001) and speech learning( r=-0.285, P=0.050). Under the relative condition, the abstract semantic deviation was positively correlated with the general symptom scale score( r=0.448, P=0.019). Under the unrelative condition, abstract vocabulary semantic deviation was positively correlated with PANSS total score( r=0.120, P=0.010), negative scale score( r=0.047, P=0.030) and general symptom scale score ( r=0.306, P=0.010). Conclusion:The semantic distance of lexical processing is abnormal in schizophrenia. The semantic deviation is related to the cognitive function index and symptom index.

ABSTRACT

Objective:To investigate the protective effect and mechanisms of umbilical cord tissue transplantation on radiation-induced learning and memory impairment in rats.Methods:Sixty SD rats were randomly divided into three groups with 20 in each group: control group, model group (whole brain X-ray irradiation, dose 20 Gy) and treatment group (whole brain X-ray irradiation, dose 20 Gy + umbilical cord tissue transplantation). The changes of body mass were observed, and the learning and memory of rats were observed by water maze test on the 14th and 28th day after irradiation, the neuron state of hippocampus was observed by HE staining, and the expressions of NF-κB pathway related proteins and IL-6 in hippocampus were detected by Western blot.Descriptive analysis and hypothesis testing were processed by SPSS 17.0.Results:(1) On the 28th day, the escaping latency in the water maze experiment of the treatment group was significantly higher than that of the control group and lower than that of the model group (control group: (11.77±3.02) s, model group: (23.75±3.27)s, treatment group: (18.49±2.32)s; t=3.940, -2.943, both P<0.05); the number of crossing platform in the treatment group was significantly lower than that in the control group and higher than that in the model group (control group: (7.20±0.84), model group (3.60±1.14 ), treatment group (5.00±1.00); t=-3.773, 2.064, both P<0.05). (2)HE staining showed that the neurons in the control group were arranged orderly and the cytoplasm was transparent.The neurons in the model group were arranged disorderly and the contraction of the cell body was triangular or irregular.The number of neurons in the treatment group was less than that in the model group. (3) On the 14th day, the relative expression of TLR4 in the treatment group was significantly higher than that in the control group and lower than that in the model group (control group: (0.69±0.03), model group: (1.06±0.11), treatment group: (0.90±0.04); t=7.275, -2.368, both P<0.05). The relative expression of NF-κB p65 in the treatment group was significantly higher than that in the control group and lower than that in the model group (control group: (1.67±0.12), model group: (2.08 ±0.06), treatment group: (1.93±0.08); t=3.236, -2.684, both P<0.05). The relative expression of IL-6 in the treatment group was significantly higher than that in the control group and lower than that in the model group (control group: (0.77±0.08), model group: (1.12±0.07), treatment group: (0.95±0.06); t=3.274, -3.495, both P<0.05). The relative expression of Bcl-2 / Bax in the treatment group was significantly lower than that in the control group and higher than that in the model group (control group: (1.40±0.52), model group: (0.48±0.06), treatment group: (0.72±0.0 3); t=-2.263, 6.350, both P<0.05). The expression trend of IL-6 and Bcl-2 / Bax protein on the 28th day was the same as that on the 14th day. Conclusion:Cord tissue transplantation can improve the learning and memory impairment caused by radiotherapy, which may be related with the inhibition of inflammation caused by radiotherapy.

ABSTRACT

OBJECTIVE: To explore the relationship between shift work and type 2 diabetes in oil workers. METHODS: A total of 2 666 oil workers in an oil group were selected as the study subjects using the typical sampling method. Questionnaire survey was conducted by a self-designed Questionnaire of Health Assessment for Oil Workers, and blood glucose level was measure. RESULTS: The prevalence of type 2 diabetes in the study subjects was 10.1%(268/2 666). The prevalence of type 2 diabetes in shift workers was higher than that in non-shift workers(13.1% vs 6.0%, P<0.01). After adjusting for the influence of confounding factors such as gender, body mass index, family history of diabetes, history of hypertension, history of hyperlipidemia, and physical exercise, multivariate logistic regression analysis results show that the longer the shift work length, the higher the risk of developing type 2 diabetes(P<0.01), workers with shift work(3 shifts in a day, 2 shifts operating) had a higher risk of type 2 diabetes than that in non-shift workers(P<0.05). CONCLUSION: The shift work length and shift workers with 3 shifts in a day, 2 shifts operating can increase the risk of type 2 diabetes in oil workers.

ABSTRACT

OBJECTIVE: To investigate the effects of manganese(Mn) and high fat diet(HFD) co-exposure on the neurological behavior and gut microbiota in mice, and to observe the correlation between them. METHODS: Specific pathogen free adult male C57 BL/6 mice were randomly divided into 4 groups. Mice in control group and Mn exposure group were fed with normal diet, while the HFD group and co-exposure group were fed with HFD. Both the Mn exposure group and the co-exposure group were exposed to 10 mg/(kg·d) manganese chloride by intraperitoneal injection, while the control group and HFD group were treated with 0.9% sodium chloride solution of the same volume, once per day for 60 consecutive days. At the end of exposure, the mice were subjected to experiments of neurological behaviors. Then, the mice were sacrificed and intestinal feces were collected. The relative abundance of gut microbiota(relative abundance>1.000%) was detected by high-throughput sequencing. RESULTS: After exposure, the body weight of the HFD group and the co-exposure group increased significantly(P<0.05), while that of the Mn exposure group decreased(P<0.05), compared with the control group. The latency, time in central, crossing, total distance and open arm time(OT%) of mice in the Mn exposure group were lower than that of the control group(P<0.05), and close arm time(CT%) prolonged(P<0.05). Compared with the control group and the HFD group, the latency, rearing, time in central, crossing, total distance, OT% and open arm entry(OE%) of mice in the co-exposure group decreased(P<0.05), and CT% increased(P<0.05). The total distance of mice in the co-exposure group was lower than that of the Mn exposure group(P<0.05). The relative abundance of Firmicutes increased(P<0.05), those of Bacteroidetes and Actinobacteria decreased in mice in the HFD group at the phylum level(P<0.05) compared with mice in the control group. The relative abundance of Firmicutes, Proteobacteria and Cyanobacteria increased(P<0.05), and Bacteroidetes and Actinobacteria decreased(P<0.05) in mice in the Mn exposure group. The relative abundance of Oscillospira, Bacteroides and Prevotella of mice in the HFD group reduced at the genus level(P<0.05) compared with the control group. The relative abundance of Lactobacillus increased in Mn exposure group(P<0.05), and Oscillospira, Bacteroides and Prevotella decreased(P<0.05). The relative abundance of Firmicutes, Cyanobacteria and Lactobacillus of mice in the co-exposure group increased(P<0.05), and those of the remaining 6 bacteria were lower(P<0.05) compared with mice in the other 3 groups. Among the mice of co-exposure group, the latency was positively correlated with Bacteroidetes(P<0.05). The rearing was positively correlated with Firmicutes(P<0.05) and negatively correlated with Actinobacteria(P<0.01). The OE% was negatively correlated with Firmicutes(P<0.05) and positively correlated with Actinobacteria(P<0.05). The crossing was positively correlated with Prevotella(P<0.05). CONCLUSION: Manganese combined with HFD had a synergistic effect on the abnormality of neurological behavior of mice. There are some correlation between the abnormality of neurological behavior and the homeostatic imbalance of intestinal flora in mice.

ABSTRACT

Objective To explore the impact of arterial injury on distal limb blood supply in lower limb trauma. Meth?ods Retrospective analysis of 93 patients with different levels of lower limb arterial injury admitted to our hospital from June 2014 to August 2017. There were 84 males and 9 females aged 43.54±9.90 years (ranging 25-65 years). Revascularization was performed through open reduction. Patients were divided into three groups according to their arterial injury locations. Proximal ves?sels were along the superficial femoral artery, from its beginning to the point where it was divided into the descending genicular ar?tery and direct periosteal branches. Intermediate vessels were from the dividing point on the superficial femoral artery to the popli?teal artery before it was divided into the medial inferior genicular artery. Distal vessels were from the dividing point on the poplite?al artery to the distal end of the peroneal artery. The duration from injury to revascularization in the three groups were 13.67±5.99 h, 11.15±4.43 h, and 11.92±5.48 h, respectively. There was no significant difference between groups (F=1.564, P=0.215). ISS in the three groups were 13.00±3.74, 12.77±3.81, and 11.50±3.99, respectively. There was no significant difference between groups (F=1.445, P=0.241). The following items were compared among the three groups, postoperative creatine kinase, arterial blood lac?tate and limb compartment cut. Results Creatine kinase of the intermediate vascular group was 8 743.15±6 968.48 u/L, proximal vascular group 1 467.67±1 810.27 u/L, distal vascular group 2 893.51±1 304.56 u/L. The data of intermediate vascular group were higher than those of proximal and distal vascular groups with significant difference among the groups (F=22.587,P=0.000). The lactate of the intermediate vascular group was 3.20 ± 1.51 mmol/L, proximal vascular group 1.63 ± 0.46 mmol/L, distal vascular group 1.85±0.69 mmol/L with significant difference among the groups (F=20.612,P=0.000). The compartment cut of the intermedi?ate vascular group was incised in 24, but not in 15. The proximal vascular group was not incised in 18, while 15 was incised and 21 not incised in distal vascular group. The rates of compartment cut were 61.5%, 0 and 41.7%, respectively with significant differ? ences (χ2=19.156, P=0.000). Conclusion In lower limb injuries, the intermediate vascular (from the superficial femoral artery after it is divided into the descending genicular artery and direct periosteal branches to the popliteal artery before it is divided into the medial inferior genicular artery) injury leads to the most severe distal limb ischemia.
