ABSTRACT

Objective:To investigate the effect of intolerance of uncertainty (IU) on state worry, state anxiety, and galvanic skin response in college students with medium and low trait anxiety.Methods:The trait anxiety inventory (TAI) and the intolerance of uncertainty scale (IUS) were used to investigate 1 378 college students in Beijing. A total of 537 individuals with medium or low trait anxiety (TAI score ≤54) were selected, from which high IU individuals (IUS score ≤58) and low IU individuals (IUS score > 58) were selected and allocated to uncertain group ( n=28) and certain group ( n=28) according to gender, age, education level and IU score. The modified NPU paradigm task, the penn state worry questionnaire(PSWQ)and the brief state anxiety measurement(BSAM) were used to assess the subjects' worry and anxiety.The galvanic skin response of individuals completing the NPU paradigm task was recorded.SPSS 26.0 was used for a two factor analysis of variance (classification: high IU, low IU; group: uncertain group, certain group). Results:The results of the two factor analysis of variance showed that the interaction between individual state anxiety classification and group was not significant( F(1, 55)=0.05, P>0.05, η2=2.16). The main effect of classification was significant( F(1, 55)=24.17, P<0.05, η2=1143.01). The anxiety level of individuals with high IU was significantly lower than that of individuals with low IU( P<0.05). The group main effect was not significant( F(1, 55)=0.03, P>0.05, η2=1.45), and there was no significant difference between the uncertainty group and the certainty group in terms of worry( P>0.05). The interaction between individual state anxiety classification and group was significant ( F(1, 55)=4.38, P<0.05, η2=3.02). The simple analysis results showed that in the uncertain group, the state anxiety of individuals with high IU was significantly lower than that of individuals with low IU ( P<0.05). In the certain group, there was no significant difference in state anxiety between individuals with high and low IU ( P>0.05). The interaction between individual galvanic skin response classification and group was not significant ( F(1, 55)=0.03, P>0.05, η2=0.00). The classification main effect was not significant( F(1, 55)=0.07, P>0.05, η2=0.00), and there was no significant difference in skin electrical activity between individuals with high and low IU ( P>0.05). But the main effect of the group was significant( F(1, 55)=4.86, P<0.05, η2=0.03). The skin electrical activity of the uncertain group was higher than that of the certain group( P<0.05). Conclusion:In the college students with medium and low trait anxiety, IU is an effective predictor of individual state worry and state anxiety under uncertain conditions.

ABSTRACT

Cardiopulmonary exercise test(CPET) is the most commonly used non-invasive tool in the world to objectively evaluate cardiopulmonary reserve function and exercise tolerance. CPET play an important role in diagnosis, risk stratification, prognosis evaluation and therapeutic planning in heart failure(HF) patients. In recent years, due to the increasing number of advanced HF patients and the paucity of heart donors, left ventricular assist device(LVAD) has represented a valid alternative to heart transplantation(HT) from bridge to transplantation indication to destination therapy. This article summarizes several topical issues regarding the current use of CPET in assessing the prognosis of HF patients, implantation and withdrawal of LVAD, postoperative right ventricular failure, and the effects of exercise rehabilitation in LVAD patients.

ABSTRACT

Objective@#To explore serum levels of brain-derived neurotrophic factor (BDNF) and glial-derived neurotrophic factor (GDNF), and whether changes of BDNF and GDNF are correlated with sleep quality and cognitive function in patients with chronic insomnia disorder (CID).@*Methods@#Fifty-seven CID patients in the Department of Sleep Disorders, Chaohu Hospital of Anhui Medical University and 30 healthy controls were enrolled from May 2017 to July 2018. Pittsburgh Sleep Quality Index (PSQI) was used to assess the degree of insomnia severity (some CID patients were monitored by overnight polysomnography). Montreal Cognitive Assessment (MoCA) scale and Nine-Box Maze were used to assess general cognitive function and specific memory function, respectively. The serum levels of BDNF and GDNF were detected using ELISA.@*Results@#Compared to the controls, CID patients had significantly higher PSQI scores (CID patients: 14.0±2.2, healthy controls: 3.9±1.1; t=28.093, P<0.01), lower MoCA scores (CID patients: 24.5±3.6, healthy controls: 26.5±0.9; t=-2.985, P<0.01), more errors in object working memory (CID patients: 1.0 (0, 1.0), healthy controls: 0 (0, 0.3)), spatial working memory (CID patients: 3.0 (2.0, 4.0), healthy controls: 1.0 (1.0, 2.0)) and object recognition memory (CID patients: 0 (0, 0), healthy controls: 0 (0, 0); Z=-2.896、-5.007、-2.306, P<0.05), and lower serum BDNF (CID patients: (19.48±7.50) ng/ml, healthy controls: (46.49±13.33) ng/ml; t=-10.274, P<0.01) and GDNF (CID patients: (32.76±14.04) pg/ml, healthy controls: (59.63±20.30) pg/ml; t=-7.240, P<0.01). The partial correlation analysis showed that in the CID patients, the levels of BDNF and GDNF were correlated with PSQI scores negatively (r=-0.293, -0.320, P<0.05) and MoCA scores positively (r=0.331, 0.295, P<0.05). The BDNF level was also correlated with the duration of disease and the errors in the spatial working memory test negatively (r=-0.319, -0.393, P<0.05), and the GDNF level was correlated with the total sleep time detected with polysomnogram positively (r=0.520, P<0.05).@*Conclusion@#Serum BDNF and GDNF levels in CID patients were lower than those in healthy controls, and correlated with sleep quality and cognitive impairment.

ABSTRACT

The development of gastritis is associated with an increased risk of gastric cancer. Current invasive gastritis diagnostic methods are not suitable for monitoring progress. In this work based on 78 gastritis patients and 50 healthy individuals, we observed that the variation of tongue-coating microbiota was associated with the occurrence and development of gastritis. Twenty-one microbial species were identified for differentiating tongue-coating microbiomes of gastritis and healthy individuals. Pathways such as microbial metabolism in diverse environments, biosynthesis of antibiotics and bacterial chemotaxis were up-regulated in gastritis patients. The abundance of Campylobacter concisus was found associated with the gastric precancerous cascade. Furthermore, Campylobacter concisus could be detected in tongue coating and gastric fluid in a validation cohort containing 38 gastritis patients. These observations provided biological evidence of tongue diagnosis in traditional Chinese medicine, and indicated that tongue-coating microbiome could be a potential non-invasive biomarker, which might be suitable for long-term monitoring of gastritis.

ABSTRACT

Objective To explore serum level of 25-hydroxy vitamin D3 (25 [OH]D3) and its correlations with sleep quality and cognitive function in patients with chronic insomnia disorder (CID).Methods Fifty CID patients,admitted to our hospital from October 1,2016 to September 1,2018,and 40 healthy controls were enrolled.Pittsburgh Sleep Quality Index (PSQI) was used to assess insomnia severity (objective sleep status being assessed using polysomnography throughout a night in some patients).Montreal Cognitive Assessment scale (MoCA) was used to evaluate the general cognitive function.Serum level of25(OH)D3 was detected by ELISA.Results As compared with the controls,CID patients had significantly higher PSQI scores (P<0.05) and statistically higher Hamilton's Depression Scale-17 scores (P<0.05).The CID patients had significantly lower MoCA scores,having more errors in object work,spatial work and object recognition memorizes in Nine-Box Maze Test than the controls.Partial correlation analysis showed that in CID patients,the level of 25(OH)D3 was negatively correlated with PSQI scores (r=-0.320,P=0.030),spatial working memory errors (r=-0.300,P=0.043) and disease course (r=-0.360,P=0.014),whereas it was positively correlated with total sleep time (r=0.515,P=0.014)and MoCA scores (r=0.422,P=0.003).Conclusion The level of 25 (OH)D3 decreases in the CID patients,which is correlated with insomnia severity and course,and may affect the cognitive function.

ABSTRACT

This study introduced the application of a log-linear model in the hybrid design of case-parents triad/control-mother dyad.Data related to the association between cleft lip with palate (CLP) and methylenetetrahydrofolate reductase (MTHFR) gene A1298C diversity was analyzed.Log-linear model based on likelihood ratio tests (LRTs) was used to analyze the relationships between mother,offspring genotypes and CLP.Data from our study noticed that children of mothers carrying the CC genotype presented a lower risk of CLP,comparing with the children of mothers carrying the AA genotype,with S2=0.45 (95%CI:0.26-0.79).Offspring that carrying the AC genotype presented a lower risk of CLP,comparing with the offspring that carrying the AA genotype,with R1 =0.69 (95%CI:0.48-0.97).However,no other types of relationships were found.The power of hybrid design was greater than the case-parents study (0.86>0.78).MTHFR A1298C polymorphism seemed to have played an important role in the etiology on both cleft lip and palate.Data from the hybrid design and the log-linear model could help researchers to explore the effects of genotypes from both mothers and the offspring.This study design would present stronger power than the regular case-parents studies thus suitable for studies on the etiology of diseases in early lives,as birth defects.

ABSTRACT

BACKGROUND:CT perfusion technology is a common non-invasive detection method, which can be used to quantitatively determine the ischemia severity and range at early stage of cerebral infarction and then judge whether ischemic brain tissues can survive or recover. OBJECTIVE:To assess the neurological function recovery of cerebral infarction rats undergoing neural stem cel transplantation using CT perfusion imaging. METHODS:A total of 60 Sprague-Dawley rats were randomly divided into control group, cerebral infarction group, transplantation group, with 20 rats in each group. Rat model of middle cerebral artery occlusion was made in the latter two groups. After 24 hours of modeling, PBS and 8×105 neural stem cels were administratedvia the tail vein into the rats in the cerebral infarction and transplantation groups, respectively. CT perfusion-weighted imaging was performed at 1, 3, 7, 14, 28 days after transplantation. Modified neurological severity scores were recorded at 1, 2, 3, 4 weeks after transplantation. Triphenyltetrazolium chloride staining was used to calculate infarct volume at 4 weeks after transplantation. Hematoxylin- eosin staining was adopted to observe pathological changes of brain tissues at 2 weeks after transplantation. RESULTS AND CONCLUSION: There were no abnormal hemodynamic changes in the control group at different time points. The transplantation group exhibited an increasing CT value with time, and the increased cerebral blood flow could improve the survival rate of neurons in the ischemic penumbra. The modified neurological severity score and infract volume in the transplantation group were both significantly lower than those in the cerebral infarction group (P < 0.05). Cel necrosis was improved obviously in the transplantation group. These results show that CT perfusion imaging can be used to observe the neurologic function recovery of cerebral infarction rats in aspects of morphology and hemodynamics.
