ABSTRACT
ObjectiveTo explore the influence of the core symptoms of attention deficit hyperactivity disorder （ADHD） on behavioral problems of children with ADHD propensity， so as to provide references for early identification and targeted intervention for children with ADHD propensity. MethodsFrom July to August 2021， 25 children with ADHD propensity were screened as the ADHD propensity group， and 25 children matched for age， gender and grade were included as the normal group in an elementary school in Guangzhou. ADHD core symptoms were assessed by the Chinese version of the Swanson Nolan and Pelham， version IV-parent form for ADHD （SNAP-IV）， and behavioral problems were assessed by Questionnaire-Children with Difficulties （QCD） and Conners Parental Symptom Questionnaire （PSQ）. Spearman correlation analysis was used to examine the correlation between ADHD core symptoms and QCD and PSQ scores， and hierarchical linear regression analysis was used to explore the effect of ADHD core symptoms on behavioral problems. Results① The differences between the groups showed that both attention deficit and hyperactivity-impulsivity factor scores were higher in the ADHD propensity group than those in the normal group （t=7.771， 6.726， P<0.01）. ② Correlation analysis showed that the attention deficit factor score was negatively correlated with QCD total score （r=-0.440， P<0.05）， and positively correlated with the learning problem factor score of PSQ （r=0.457， P<0.05）. The score of hyperactivity-impulsivity was negatively correlated with score of anxiety factor in PSQ （r=-0.457， P<0.05）， and positively correlated with impulse-hyperactivity factor score （r=0.552， P<0.01）. ③ Hierarchical linear regression analysis showed that the attention deficit factor score negatively predicted the total score of QCD （B=-0.682， P<0.05， R2=0.468）. The hyperactivity-impulsivity factor score had a negative predictive effect on the anxiety factor score of PSQ （B=-0.048， P<0.05， R2=0.367）， and had a positive predictive effect on the impulsivity-hyperactivity factor score （B=0.077， P<0.01， R2=0.424）. ConclusionChildren with ADHD propensity have significant attention deficit symptoms， hyperactivity-impulsivity symptoms and behavioral problems， and the attention deficit may be the main cause of their daily behavioral problems， while hyperactivity-impulsivity may be the main cause of their impulsive-hyperactivity problems.
ABSTRACT
Objective To evaluate the application of atherogenic index of plasma (AIP) and intima-media thickness of carotid artery (CA-IMT) in renal arteriolar sclerosis patients with chronic renal failure.Methods One hundred and twenty nine patients with chronic renal failure patients underwent ultrasound-guided percutaneous renal biopsy from October 2013 to June 2014,the biopsy results showed that renal arteriolar sclerosis was identified in 72 patients (atherosclerosis group) and no renal arterioles sclerosis was detected in 57 patients (non-atherosclerosis group);71 healthy adults were enrolled in the study as controls.The age,height,body weight,systolic and diastolic blood pressure,the indexes of blood lipid and renal function were documented and compared among three groups.The correlation of AIP and CBMmax of common carotid artery and carotid bifurcation with blood lipid level and renal function was analyzed.Results There was significant difference in body weight among patients with atherosclerosis [(70.77 ± 14.27) kg],without atherosclerosis [(60.63 ± 12.12) kg] and the controls [(64.20 ± 8.13) kg] (t =3.071,3.391,all P ＜ 0.05).The TG [(2.43 ± 1.61) mmol/L vs.(1.02 ± 0.37) mmol/L],TC [(7.40 ± 8.80) mmol/L vs.(4.53 ±0.67)mmol/L],LDL-C[(4.40 ±2.13) mmol/L vs.(2.85 ±0.70) mmol/L],AlP[(0.15 ± 0.351) vs.(-0.127 ± 0.184)] of the atherosclerosis group were higher than those of control group (t =5.975,2.252,2.614,-5.467,all P ＜ 0.05).The HDL-C of atherosclerosis group was lower than that of control group [(0.78 ±0.16) mmol/L vs.(1.29 ±0.21) mmol/L,t =4.750,P ＜0.05].The Scr[(117.24 ± 94.27) mmol/L vs.(64.16 ± 13.42) mmol/L],BUN [(6.73 ± 3.58) mmol/L vs.(4.66 ± 1.08) mmol/L] of the atherosclerosis group were higher,and the GFR was lower [(65.60 ±23.00)ml · min-1 · 1.73 m-2 vs.(124.78 ± 24.35)ml · min-1l.73 m-2,t =5.118] than those of control group (t =4.730,4.702).The Scr of the atherosclerosis group was higher,and the GFR was lower [(65.60 ± 23.00) ml · min-1 · 1.73 m-2 vs.(95.60±53.00)ml · min-1 · 1.73 m-2,t =3.514] than those of the non-atherosclerosis group [(117.24 ± 94.27) mmol/L vs.(71.35 ± 42.18) mmol/L,t =3.690].There were positive correlation between TG and LDL-C (r =0.828,0.323,P ＜ 0.05) and negative correlation between AIP and HDL-C (r =-0.489,P ＜0.05).There was positive correlation of CBMmax with Scr,BUN and AIP (r =0.394,0.289,0.528,all P ＜ 0.05),and negative correlation between CBMmax and GFR (r =-0.277,P ＜ 0.05).Conclusion Body weight,GFR,AIP and CBMmax are useful indicators in evaluation of renal arteriolar sclerosis in patients with chronic renal failure.AIP is a sensitive index for abnormal blood lipid level.AIP and CBMmax are important risk factors in chronic renal failure patients with renal arteriolar sclerosis.
ABSTRACT
BACKGROUND:Urine-derived stem cels are most likely to come from the kidney tissue, and therefore, these cels are more adaptable to kidney microenvironment, providing a new option for the treatment of kidney diseases. OBJECTIVE: To explore the therapeutic efficacy of human urine-derived stem cels on chronic nephropathy rats. METHODS:The fresh urine samples of healthy people were colected, and then human urine-derived stem cels were extracted and cultured in vitro. Twenty Sprague-Dawley rats were used to prepare chronic nephropathy models, and given injection of human urine-derived stem cel suspension (experimental) or normal saline (control) into the renal cortex, respectively. Another 10 healthy rats were used as controls. Therapeutic effects on renal function were assessed by detection of serum creatinine level and glomerular filtration rate in the three groups. The kidney tissues of rats were taken and observed histomorphologicaly in each group. RESULTS AND CONCLUSION: Human urine-derived stem cels were found to remarkable improve rat’s renal function as wel as reduce the histomorphological changes in the kidney tissues of rats. Compared with the control group, the serum creatinine level was decreased while the glomerular filtration rate was increased significantly in the experimental group; CD68 expression and infiltration of interstitial inflammatory cels were also markedly reduced in the experimental group. To conclude, human urine-derived stem cels can improve the renal function of chronic nephropathy rats.
ABSTRACT
Objective To analyze the adverse drug reactions of Imipenem/cilastati for the treatment of diseases in recent year and supply useful information for the rational application in clinical therapy.Methods The literatures since 1995 about adverse drug reactions of Imipenem/cilastati from the data-base (CNKI) were collected and then the data were analyzed.Results The incidence rate of adverse reactions of Imipenem/cilastati in clinical therapy was raised and many in vivo systems were damaged from the adverse reactions.According to the actual situation of adverse reactions, those treatment can be given to get better clinical results, which was given oxygen, adjusting the dosage and dosing interval,drug withdrawal and other treatment;patients whose nervous system damage was given a small amount of sedatives or antipsychotics, patients whose cardiovascular system damage were given nutrition, renal dysfunction were treated with hemodialysis treatment.Conclusion It is necessary to use Imipenem/cilastati rationally to avoid the adverse drug reactions.
