ABSTRACT
Objective:To explore the influence of tomoxetine hydrochloride on the cognitive processing of children with attention deficit hyperactivity disorder (ADHD).Methods:From January 2018 to July 2021, 62 ADHD children who were treated with tomoxetine hydrochloride for the first time for(8±4) weeks were selected as the ADHD group.And 62 healthy children matched with age and sex were selected as the healthy control group.Pre-test and post-test by the Das-Naglieri: Cognitive Assessment System(DN: CAS) were performed to evaluate the cognitive function of all individuals.The differences of cognitive processing in pre-treatment and post-treatment of ADHD group were compared with those in healthy control group.The difference between before and after treatment of ADHD group was also compared.SPSS 26.0 statistical software was adopted for statistical analysis.The scores of ADHD group pre-treatment and post-treatment were compared by paired sample t-test, and the scores of ADHD group pre-treatment and post-treatment were compared with those of healthy control group by independent sample t-test. Results:Compared with healthy control group, there were lower of planning score((18.77±5.92) vs (28.56±5.55)), attention score((22.24±5.93) vs (29.56±6.16)), simultaneous processing ((34.21±7.75) vs (37.61±6.29)), successive processing((30.37±7.12) vs (33.74±5.43)), and the total scores((105.60±21.29) vs (134.84±22.87)) in ADHD group before treatment, and there were significant differences( t=9.49, 6.74, 2.68, 2.96, 7.36, all P<0.05). Compared with healthy control group, there were lower of planning score ((22.13±5.99)s), attention score((25.26±7.11) with significant difference( t=6.20, 3.60, both P<0.05) in ADHD group after treatment.And there was no significant difference in the simultaneous processing test and the successive processing test after treatment compared with the healthy control group(both P>0.05). In ADHD group, the scores of planning, simultaneous processing, attention, successive processing and the total score were significantly higher after treatment than those before treatment and there were significant differences( t=-6.03, -4.13, -4.77, -5.48, -8.59, all P<0.05). (2) Compared with the healthy control group, there were lower of matching number score and other 8 sub-test scales in DN: CAS test in ADHD group before treatment, and the differences were statistically significant (all P<0.05). Meanwhile, there were still lower of matching number score and other 4 sub-test scales in DN: CAS test in ADHD group after treatment, and the differences were statistically significant (all P<0.05). The matching number score and other 10 sub-test scales in DN: CAS test in ADHD group after treatment were all higher than those of before treatment(all P<0.05). Conclusion:The planning, attention, simultaneous processing, successive processing and total cognitive function of ADHD children were significantly improved after treatment with tomoxetine hydrochloride, special for simultaneous processing and successive processing.
ABSTRACT
Objective:To explore the effect of moderate intensity physical exercise on depression, anxiety and cognitive function of schizophrenic patients and its possible biochemical mechanism.Methods:Totally 148 patients with schizophrenia who were hospitalized in hospital from March 2019 to March 2021 were randomly divided into control group ( n=75) and exercise group ( n=73). The patients of the two groups were given drug treatment and routine exercise according to clinical practice, and the patients in exercise group were given additional medium-intensity physical exercise.Self-rating anxiety scale (SAS) and self-rating depression scale (SDS) were used to evaluate the poor mental state of the subjects.The verbal fluency task(VFT), digital span test(DST), trail making test-A(TMT-A) and the positive and negative symptom scale (PANSS) were used to evaluate cognitive function.The levels of endocannabinoids (eCBs) receptors were detected by high performance liquid chromatography, and the levels of monoamine neurotransmitters and eCBs in the patients' serum were determined by enzyme-linked immunosorbent assay (ELISA). SPSS 19.0 software was used for statistical analysis.The measurement data between the two groups were compared by t-test and the counting data between the two groups were compared by χ2 test. Results:(1) After effective intervention, the scores of SAS, SDS, TMT-A and PANSS of the two groups were significantly lower than those before intervention, and the difference before and after intervention between the two groups was statistically significant( t=6.00, 6.52, 25.79, 17.03, all P<0.01). The scores of SAS, SDS, TMT-A and PANSS after intervention in the exercise group were significantly lower than those in the control group( t=4.66, 20.88, 6.61, 8.95; all P<0.01). The number of VFT and DST in the two groups after intervention were significantly higher than those before intervention, and the differences before and after intervention between the two groups were statistically significant( t=13.78, 22.76, both P<0.01). After effective intervention, the number of VFT and DST in exercise group were significantly higher than those in the control group( t=5.02, 5.15, both P<0.01). (2) After effective intervention, the contents of monoamine neurotransmitters and eCBs in serum of the two groups were significantly higher than those before intervention, and HVA level ((63.68±6.99) pg/mL), MHPG level ((175.90±16.22) pg/mL), 5-HIAA level ((29.94±4.19) pg/mL) and CBR1 level ((6.70±1.40)μg/L), 2-AG level ((61.90±5.73)pmol/g) and AEA level ((76.48±6.59) pmol/g) in exercise group were significantly higher than those in the control group ((52.97±5.37)pg/mL, (138.50±11.52)pg/mL, (23.87±3.15)pg/mL, (5.71±1.29)μg/L, (52.13±5.14)pmol/g, (67.66±5.88)pmol/g)( t=10.43, 16.21, 10.91, 8.65, all P<0.01). Conclusion:Moderate intensity physical exercise can significantly improve their depression, anxiety and cognitive function, which may be related to regulating the levels of ECBS and their receptors in patients with chronic schizophrenia to increase monoamine neurotransmitters.
ABSTRACT
Objective@#To summarize the progress of injury cohort studies over the world.@*Methods@#Relevant information of injury cohort publications published before December 2017 were retrieved from PubMed, WanFang and China National Knowledge Infrastructure (CNKI) databases, consisting of the starting year, category of injury, study population, sample size, countries, follow-up duration, main exposure variables, outcome variables and method of data collection, and statistical methods.@*Results@#A total of 295 studies were included in the analysis. The overall number of injury cohort studies increased with a peak in 2000, and then decreased. The top three countries that most frequently published cohort studies were the United States (52), Sweden (46) and the United Kingdom (37). A total of 29 published injury cohorts were identified in China, about 3, 23 and 3 cohort studies from the mainland of China, Taiwan Province, and Hong Kong Specific Administrative Region, respectively. The majority of cohort studies involved a single injury cause (93.6%); the most common injury causes included suicide/self-harm (46.1%), falls (17.3%) and road traffic injuries (14.6%). For the published cohort studies, exposure variables and outcome events varied with injury causes, primarily being collected through data registration system, national survey data, questionnaire survey, telephone interviews, and other means.@*Conclusion@#A number of injury cohorts have been established worldwide, and few in the mainland of China. The existed cohort studies could offer important references for the design of large-scale, multi-center and high-quality injury cohort in China in the future.

ABSTRACT
Objective To explore the effect and mechanism of Cyclosporin A (CsA) and cholic acid on reducing the human liver cell damage induced by α-amanitin (AMA).Methods According to the previous research results,the minimum hepatocellular survival concentration against αt-AMA (1.4 g/L),the experiment was conducted in 5 groups:control group,damage group,glycochenodeoxycholic acid group,CsA group,and CsA combined with cholic acid group (CsA+ taurocholic acid,CsA+ chenodeoxycholic acid,CsA+ glycocholic acid,CsA+ glycochenodeoxycholic acid,and CsA+ taurochenodeoxycholic acid).For each group,there were 3 time points for observation (24 h,48 h and 72 h after attacking),CsA and CsA+ glycochenodeoxycholic acid was used to protect hepatocytes,respectively,and morphological changes in cells were observed with inverted phase contrast microscope,and the live cells were counted by 3-(4,5-dimethyl-2-thiazolyl)-2,5-diphenyl-2-H-tetrazolium bromide (MTT) method,and aspertate aminot ransferase (AST) and alanine aminotransferase (ALT) in the culture supernatant were detected by biochemical method.Results Compared with the control group,hepatocellular growth in the injury group was obviously suppressed,with progressive cellular apoptosis and significantly decreased absorbance value of MTIT (0.345 ± 0.021);the activity of AST and ALT increased gradually,reaching the highest after 72 h [(98.4 ± 6.7) U/L and (116.2 ± 9.5) U/L,respectively].Compared with injury group,broken organelles decreased significantly and absorbance value elevated in glycochenodeoxycholic acid group,CsA group and CsA combined with cholic acid group,and at each time point,the highest absorbance value in the CsA+ taurochenodeoxycholic acid group [the highest was (0.656 ± 0.014),P ＜ 0.05];at the same time,the activity of AST and ALT didn't increase obviously,at each time point,the lowest in CsA+ taurochenodeoxycholic acid group [the lowest was (22.3 ± 6.2) U/L and (20.2 ± 5.4) U/L,P ＜ 0.05,respectively].Conclusions CsA,as well as cholic acid,can protect human liver cells from the attack of α-AMA.The mechanism may be CsA,as an organic anion transfer peptide in humans (OATP1B1 and OATP1B3) suppressant,inhibits the absorption of α-AMA.The joint application of CsA and taurochenodeoxycholic acid is superior to the single OATP substrate or inhibitor.
ABSTRACT
Objective To explore the relationship between the Chinese Version Wechsler intelligence scale for children(C-WISC) and the Das-Naglieri cognitive assessment system(DN:CAS) in children with attention deficit hyperactivity disorder (ADHD).Methods Thirty-two children with ADHD were evaluated with C-WISC and the digital remote assessment system——DN:CAS,and both results were administered for correlation analysis.Results The results showed that there was a strong correlation between the full intelligence quotient (FIQ) of C-WISC and the full score of DN:CAS,also the scores in Plan,Simultaneous,and Successive of DN-CAS,and the correlation coefficient was between 0.6 to 0.8.There was a strong correlation between the full score of DN:CAS and the verbal comprehension IQ (VCIQ),perceptual organization IQ (POIQ),memory/concentration IQ (M/CIQ),verbal IQ (VIQ),and performance IQ(PIQ) of C-WISC,as the correlation coefficient ranges from 0.6 to 0.8.There was also a strong correlation between the score in Planning and VCIQ,POIQ,M/CIQ,VIQ of C-WISC.As to the score in Simultaneous of DN:CAS and POIQ,VIQ,PIQ of C-WISC,the correlation was also strong with the correlation coefficient ranging from 0.6 to 0.8.For the rest of the sub-tests of C-WISC and DN:CAS,there was moderate correlation between them,the correlation coefficient was from 0.4 to 0.6.Conclusions These results show that the correlation between C-WISC and DN:CAS in children with ADHD is significant.The correlation coefficient shows diversity in the sub-tests of C-WISC and DN:CAS.
