ABSTRACT
Objective:To observe the effect of methylphenidate hydrochloride (MPH) combined with mentalization-based family therapy (MBFT) on clinical efficacy and social function in children with attention deficit hyperactivity disorder (ADHD).Methods:Sixty-four children with ADHD diagnosed in Wuxi Children's Hospital and Affiliated Hospital of Jiangnan University from June 2019 to May 2021 were selected and divided into observation group ( n=32) and control group ( n=32) according to the random number table.Children in both groups received methylphenidate hydrochloride extended-release tablets, while those in the observation group were given additional MBFT.The duration of treatment was 12 weeks in both groups.The parent symptom questionnaire (PSQ), swanson nolan and pelham-version Ⅳ (SNAP-Ⅳ) parent Al scale, and Weiss impairment functional scale (WFIRS-P) were used to evaluate the effectiveness of treatment.Statistical analysis was performed by SPSS 25.0 statistical software.In particular, the χ2 test was used for counting data and the paired sample t test was used for comparison of measurement data between the two groups before and after treatment. Results:(1) All the PSQ dimension scores of patients in the observation group and the control group after treatment were significantly lower than those before treatment (all P<0.01). Compared with the control group after treatment, the PSQ dimension scores of personality and behavior problems ((1.25±0.15), (0.94±0.18), t=7.484, P<0.001), learning problems ((1.57±0.16), (1.32±0.20), t=5.522, P<0.001), psychosomatic disorders ((0.56±0.11), (0.44±0.13), t=3.986, P<0.001), impulse hyperactivity ((1.76±0.23), (1.54±0.25), t=3.663, P<0.001), anxiety ((0.94±0.12), (0.76±0.11), t=6.255, P<0.001) and hyperactivity index ((1.74±0.19), (1.51±0.16), t=5.238, P<0.001) decreased significantly in the observation group after treatment.(2) Compared with the pre-treatment period, the SNAP-Ⅳ scale scores of attention deficit, impulsivity-hyperactivity and oppositional defiance were significantly lower in both groups after treatment (all P<0.01); and compared with the control group, the SNAP-Ⅳ scale scores of the above three dimensions were significantly lower in the observation group (all P<0.01). (3) All six dimensions (family, learning and school, life skills, self-management, social activities, and risk-taking activities)of the WFIRS-P scale were significantly lower in the children in the observation group after treatment compared with those before treatment (all P<0.01), and all the six dimensions of the WFIRS-P scale were significantly lower in the observation group compared with those in the control group (all P<0.01). Conclusion:Methylphenidate hydrochloride extended-release tablets combined with MBFT can significantly improve the clinical symptoms and social function of children with ADHD.
ABSTRACT
Objective:To investigate the clinical efficacy of atomoxetine combined with cognitive-behavioral therapy (CBT) on children with attention deficit hyperactivity disorder (ADHD).Methods:Totally 104 children diagnosed with ADHD were randomly divided into atomoxetine group ( n=34), CBT group ( n=35) and atomoxetine combined with CBT group ( n=35). After 12 weeks of treatment, questionnaire-children with difficulties (QCD), Swanson child behavior checklist (SNAP-Ⅳ) and Conners parents rating scales (CPRS) were used to evaluate the efficacy and recorded the adverse reactions during the treatment. SPSS 23.0 software was used for statistical analysis. Paired sample t-test was used to compare the scores of the same group before and after treatment, and one-way ANOVA was used to compare the difference between the three groups after treatment. Results:(1)Compared with baseline, the score of QCD increased(32.96±3.01, 43.00±2.22) ( t=-13.35, P<0.01) , while the attention deficit(15.67±3.46, 6.07±1.73), hyperactivity/impulse(13.59±3.41, 7.30±2.43), opposition disobedience(9.85±3.98, 2.59±2.17) and total score(39.11±6.65, 16.59±3.91) of SNAP-Ⅳ decreased in atomoxetine combined with CBT group after treatment ( t=14.96, 10.87, 11.77, 21.49, all P<0.01). The factor scores of behavior problems(0.81±0.30, 0.70±0.26), learning problems(1.58±0.31, 0.32±0.13), psychosomatic disorders(0.22±0.25, 0.16±0.20), impulse hyperactivity(1.27±0.37, 0.71±0.18), anxiety(0.32±0.26, 0.23±0.17) and hyperactivity index(1.19±0.40, 0.79±0.22) of CPRS also decreased ( t=2.71, 21.23, 2.41, 8.87, 2.96, 6.19, all P<0.05) in atomoxetine combined with CBT group after treatment. (2) After treatment, the changes of QCD scores, attention deficit dimension in SNAP-Ⅳ scale, learning problems and impulse hyperactivity dimension in CPRS scale of the three groups before and after treatment were statistically significant (all P<0.05). (3) Post LSD comparison showed that the change in CBT group was significantly lower than that in atomoxetine group and atomoxetine combined CBT group in QCD score(both P<0.05). In the dimension of attention deficit of SNAP-Ⅳ, the difference in CBT group was significantly lower than that in atomoxetine combined CBT group ( P<0.01). In the learning problems and impulse hyperactivity dimensions of CPRS, the changes of atomoxetine combined with CBT group were significantly higher than those of atomoxetine group and CBT group (all P<0.01). Conclusion:Atomoxetine combined with CBT has better curative effect than atomoxetine or CBT alone in patients with ADHD. It can effectively improve the core symptoms and daily life function of ADHD children, and has high safety.
ABSTRACT
Objective:To observe the expression of molecular chaperone-mediated autophagy in hippocampal neurons and its relationship with brain injury after recurrent-status seizures.Methods:Seven-day-old SD rats were divided into two groups according to simple randomization: the control group (NS group, 6 rats) and the recurrent-seizure group (RS group, 39 rats). Rats in the RS group were subjected to recurrent seizures after repeated inhalation of flurothyl, with 30 minutes once each day for consecutive 7 days.A total of 30 convulsive models were successfully established (9 rats that failed to establish models were discarded), and they were further divided into 0 h, 1.5 h, 3 h, 12 h and 24 h after the last seizure according to simple randomization, with 6 rats in each group.Western blot and reverse transcription-polymerase chain reaction (RT-PCR) were adopted for the observation of the expression of molecular chaperone-mediated autophagy markers [heat shock cognate protein 70 (Hsc70), lysosome-associated membrane protein type 2a (LAMP-2a), heat shock protein 40(HSP40) and heat shock protein 90(HSP90)] in hip-pocampal neurons, and apoptosis was detected by TdT-mediated dUTP nick-end labeling (TUNEL).Results:(1) RT-PCR and Western blot showed that, compared with the NS group, the expression of Hsc70, as a molecular chape-rone, started to increase at 1.5 h and continued until 24 h after the last seizure in the RS group ( P<0.05). HSP90 increased immediately after the last seizure and lasted until 24 h after the seizure ( P<0.01); the expression of HSP40 and LAMP-2a also showed high expression after the last seizure episode ( P<0.05). (2) The TUNEL method showed that the number of apoptotic cells in the hippocampal CA1 region increased significantly at 3 h (36.33±5.16)/40 field, 12 h (44.83±4.83)/40 field and 24 h (54.83±7.16)/40 field after the last seizure compared with NS group(15.16±2.48)/40 field ( P<0.01). (3) Pearson correlation analysis showed that the level of apoptosis in hippocampal CA1 region of rats after recurrent seizures was positively correlated with the expression of molecular chaperone marker molecules (Hsc70: r=0.734, P=0.001; LAMP2a: r=0.790, P<0.001). Conclusions:After recurrent seizures in developmental rats, the presence of increased expression of multiple molecular chaperone-mediated autophagy, which may positively correlate with apoptosis, may be involved in the process of brain injury.
ABSTRACT
Objective To investigate the the association between psychological behavior and self-awareness of obese children and family factors,in order to provide scientific basis for clinical intervention in obese children. Methods Fifty children with obesity ( obesity group) and fifty healthy children ( control group) were included in the study. All children were evaluated with the Achenbach Child Behavior Checklist (CBCL),Piers-Harris Child's self-concept Scale ( PHCSS), Family Environment Scale-Chinese Version ( FES-CV) and Egma Minnen av Bardndosnauppforstran(EMBU). Moreover,correlation analysis was applied in the study to explore family factors affecting behavioral problems and self-awareness of obese children. Re-sults Compared with control group,significant higher ratio of abnormal behaviors was found in children with obesity (P<0. 05). FES-CV showed that the degree of expressiveness((3. 16±1. 93),(4. 65±1. 02)),intel-lectual-cultural orientation((5. 31±1. 28),(6. 10±1. 83)) and active-recreational((2. 78±1. 36),(4. 84± 1. 72)) were lower than control group,and the degree of family conflict((4. 11±1. 45),(3. 32±1. 27)) and control((6. 42±1. 37),(5. 09±1. 65)) were higher in children with obesity (P<0. 05). Moreover,EMBU showed that emotional warmth score was significantly lower in obese group than that in control group (P<0. 01),and the scores of parent's rejection,father's severity,parent's over-interference,and mother's over-protection were significantly higher than the scores in control group(P<0. 05). In obese group,the correlation analyses showed a negative association between social withdrawal in children's behavioral problems and fami-ly expressiveness (r=-0. 62,P<0. 01),and a positive association between aggressivity and family conflict (r=0. 39,P<0. 05). There was a positive correlation between internalizing behavioral problems and mother's over-protection and over-interference(r=0. 60,P<0. 01). Low self-awareness was positive associated with parent's rejection and father's severity(r=0. 46,0. 51,0. 44 respectively,P<0. 05). Conclusion A signifi-cant higher risk of abnormal psychological behaviors and low self-concept can be found in children with obe-sity,which can closely related to family factors.
ABSTRACT
Liver failure is a common clinical syndrome of serious liver diseases with a high mortality rate. Artificial liver support system can significantly reduce the mortality rate of patients with liver failure and is widely used in clinical practice. Due to the shortage of blood resource, the increase in blood-borne diseases, increased demands for liver transplantation, and the change in treatment concepts, single non-biological artificial liver treatment is often unable to satisfy clinical needs, and it is urgent to develop new therapeutic paradigms of non-bioartificial liver. This article reviews the changes and perspectives of non-biological artificial liver in the treatment of liver failure.
ABSTRACT
Liver failure has various clinical types, a complex pathogenesis, and rapid disease progression, as well as a high mortality rate. Liver failure caused by hepatitis B virus infection is the most common type in China with severe conditions, various complications, and a mortality rate as high as 40%-90%. Invasive fungal disease secondary to acute-on-chronic liver failure can affect patients’ prognosis and increase mortality rate. This article introduces the research advances in hepatitis B-related liver failure, artificial liver, and invasive fungal disease secondary to acute-on-chronic liver failure in 2016.
ABSTRACT
Objective To investigate the characteristics of quality of life (QoL) and self-awareness in girls with idiopathic central precocious puberty (ICPP) and the correlation between QoL and the self-awareness.Methods The inventory of subjective life quality (ISLQ) and Children's self-concept scale (PHCSS) were employed to evaluate the level of QoL and self-awareness in 24 ICPP girls with ICPP (ICPP group) and 24 normal control girls (control group),and the correlation analysis between QoL and the self-awareness in the ICPP group was made.Results The score of overall (70.85±14.11 vs 80.21±6.07) and emotion component satisfaction (62.61± 12.91 vs 73.74±5.02),dimensions satisfaction on school life (5.80± 1.44 vs 6.69±0.65),depression experience (6.55± 1.14 vs 7.29±0.45),anxiety experience (5.93± 1.35 vs 6.96±0.82) and physical emotion (6.33±1.17 vs 7.12±0.83) in ICPP group was respectively lower than control group (P＜0.05).There was no difference in cognitive component between control group and ICPP group,as well as for other dimension satisfaction.Moreover,the score in total self-awareness,physical appearance and anxiety in ICPP group was respectively lower than those in control group (P＜0.05).In addition,a positive correlation was found between the subjective QoL and the children self-concept in ICPP group (P＜0.01).Conclusion The girls with ICPP show a lower subjective QoL and self assessment than normal girls.It is important to take care of the psychological feature of the girls with ICPP to improve the self-assessment and overall QoL during the medication.
ABSTRACT
BACKGROUND:It is very nscessary for the prevention and treatment of ostaoarthritis(OA)to understand the tensile mechanical properties of lateral collateral ligaments(LCLs)of knee joints with osteoarthritis,while reports on it are still few.OBJECTIVE:To compare the LCL tensile mechanical property indexes of knee joints between normal animals and OA medels established for this purpose,and to provide qualitative and quantitative referential data about effects of OA on the LCL tensile mechanical properties of animal knee joints.DESlGN,TIME AND SETTING:A randomized controlled trial was finished at the Mechanical Expedmental Center of Jilin University from December 20th to 30th in 2008.MATERIALS:A total of 20 male SD rats of 6 months old were divided into a normal control group and a model group,with 10ones in each group.METHOOS:Rats in the model group were copied into OA models.after which test on tensile was performed to each of the ten rats in the two groups at the speed of 5mm/min on Universal Testing Machine,Shimadzu.Data obtained from the test were processed in polynomial though least square method.MAIN OUTCOME MEASURES:Tensile maximum load.maximum displacement,maximum stress,maximum strain and stress-strain curves.RESULTS:The tensile maximum load,maximum stress,maximum displacement and maximum strain in the normal control group and the model group were(12.754±2.795)N,(27.681±5.832)MPa,(2.754±0.707)mm,(11.679±2.373)%and (7.183±1.817)N,(16.162±3.403)MPa,(1.827±0.768)mm,(8.019±2.811)% respectively,from which we could see that each index in the normal control group was greater than that in the model group obviously (P＜0.05).CONCLUSION:The tensile maximum load,maximum stress,maximum displacement and maximum strain all decreased after OA,which indicates that osteoarthritis has certain effects on tensile mechanical properties of LCLs of knee joints as well as stress relaxation.
