RESUMO
Objective To investigate the influence of parental compliance on the therapeutic effect of children with epilepsy.Methods Two hundred and sixty children with epilepsy and their parents admitted to the First People's Hospital of Wenling from December 2013 to June 2016 were enrolled,and the classical Morisky medication adherence questionnaire (MMAS-8) was applied to evaluate the compliance of parents for treatment of their children with epilepsy;after the patient taking drug for 3 days,fasting venous blood was collected in the morning,the concentration of the blood drug was tested and the influence of parent compliance on the blood drug concentration of the child with epilepsy was evaluated.Results In 260 patients,122 cases took karma form,and 138 cases took valproate orally.There were parents with good medication compliance in 130 cases (50％),medium medication compliance 80 cases (30.76％) and poor adherence to the doctor order in 50 cases (19.23％).In cases using medication irregularly,there were 26 cases sometimes without taking any drug (10.0％),17 patients' medication being interrupted (6.54％) and 10 cases having excessive medication (3.85％);no relationships were found between parental compliance and each of the following items,family role,occupation and age (all P ＞ 0.05);and the compliance was related to gender,indicating that women's good compliance level was higher than that of males';the education level was positively proportional to the compliance,and the compliance of parents with senior high school or above degree was higher than those with primary school and junior secondary school levels (83 cases vs.9 cases,38 cases,both P ＜ 0.01).Under situation of parents with poor compliance,their children had blood drug concentration higher or lower than proper range of drug level (high in 22 cases,low in 41 cases,higher than the result in good compliance 0 cases and 17 cases respectively),thus seriously affected the safety and efficacy of the treatment;the patients' frequency of irregular medication in parents' good compliance group was significantly lower than that in parents' poor compliance group [3.08％ (4/130) vs.72.0％ (36/50),P ＜ 0.05].Conclusion To improve the therapeutic effect of epileptic children,their parental good cooperation is necessary.
RESUMO
Objective To explore the change of glyoxalase I in type 2 diabetic ocular muscles palsy (DOMP) and its associations with advanced oxidation protein products (AOPP) and oxidative stress. Methods 58 DOMP patients, 50 T2DM and 30 normal controls were enrolled in this study. Levels of blood lipids, fasting blood glucose, hemoglobin A1c, insulin, serum glyoxalase I, AOPP, malondialdehyde (MDA), superoxide dismutase (SOD) and total antioxidant capacity (T-AOC) were measured. Homeostasis model assessment was performed to evaluate the status of insulin resistance (IR). Results Levels of high-density lipoprotein cholesterol, SOD and T-AOC were positively correlated with glyoxalase I and inversely associated to AOPP. Levels of triglycerides , low-density lipoprotein cholesterol , fasting blood glucose , hemoglobin A1c , IR and MDA were negatively correlated with glyoxalase I and positively related to AOPP. AOPP had an inverse association with glyoxalase I (r = -0.823, P < 0.001). Multivariate regression analysis showed that serum levels of glyoxalase I (Sβ = 0.554) and AOPP (Sβ= -0.469) were influencing factors of groups. Conclusion Serum glyoxalase I levels were significantly decreased in DOMP and correlated with AOPP and levels of oxidative stress , which suggest that glyoxalase I could play crucial roles on the development of DOMP.
RESUMO
Objective To investigate whether metabolic pathway-related gene polymorphisms are associated with arterial plaque stability and their gene-gene interactions increase the risk of cerebral infarctions.Methods Totally 294 patients with atherothrombosis stroke admitted to the Department of Neurology, the Third Affiliated Hospital of Wenzhou Medical University from September 2010 to December 2012 were divided into a carotid vulnerable plaque group ( n=69 ) and a stable plaque group ( n=225 ) according to the results of carotid B-mode ultrasonography.A total of 282 healthy volunteers excluded carotid plaque and stroke were enrolled as well.Genetic polymorphisms of ALOX5AP and CYP3A5, CYP2C9*2, CYP2C9*3 and EPHX2 were genotyped using polymerase chain reaction and mass spectrometry analysis.The SPSS16.0 software was used to compare genotype frequencies and the generalized multifactor dimensionality reduction ( GMDR ) method was applied for gene-gene interaction analyses.Results The results showed that EPHX2 GG genotype might protect against stroke ( OR =0.520, 95% CI 0.288 -0.940, P=0.030).The distribution of CYP3A5 genotypes showed statistically significant differences (χ2 =7.284, P=0.026) between the vulnerable plaque ( AA: 5 cases, AG: 36 cases, GG: 28 cases) and stable plaque ( AA: 26 cases, AG: 77 cases, GG: 122 cases ) groups.Multivariate Logistic regression analysis showed that the GG genotype of CYP3A5 was protective factor for unstable plaques ( OR=0.405, 95%CI 0.178 -0.920, P =0.031 ).Differences in other SNPs did not reach statistical significance between the two groups.The GMDR analysis showed a significant gene-gene interaction between SG13S114 and A6986G, with scores of 10 for cross-validation consistency and 9 for the sign test (P=0.011).The best model for ischemic stroke was found to be SG13S114 AA and A6986G AA.Adjusting for age, hypertension and diabetes, the certain gene-gene interaction predicted a significantly higher risk of cerebral infarction (OR=1.804, 95%CI 1.180-2.759, P=0.006).Conclusions The EPHX2 G860A gene might be linked with the incidence of cerebral infarctions.Only a CYP3A5 gene polymorphism might be associated with carotid plaque instability in patients with stroke.The gene-gene interaction predicts a significantly higher risk of cerebral infarction.There is a 1.804-fold increased risk for ischemic stroke in individuals with these combined genetic factors.
RESUMO
Objective:To explore the relationship between tissue factor (TF),tissue factor pathway inhibitor (TFPI) and the severity in patients with diabetic cerebral infarction.Methods: 226 patients with diabetic cerebral infarction were included into the study,National Institute of Health Stroke Scale ( NIHSS) was used to evaluate the severity of CIS.The single factor analysis and multiple regression analysis were used to explore the relationship between TF , TFPI and the severity.Results: The concentrations of TF,TFPI,TF/TFPI,cholesterol and triglyceride in the NIHSS≤12 group were significantly lower than that in the NIHSS>12 group ( P<0.05);the NIHSS was significantly positive correlate with TF (r=0.354,P=0.012),TFPI (r=0.302,P=0.027),TF/TFPI (r=0.410,P=0.000),cholesterol (r=0.364,P=0.006) and triglycerides (r=0.334,P=0.018);Multiple linear regression analysis showed that the TF , TFPI, TF/TFPI, cholesterol were independent risk factors of the severity in patients with diabetic cerebral infarction.Conclusion:The level of TF and TFPI could reflect the severity in patients with diabetic cerebral infarction according to the NIHSS.
RESUMO
Objective To investigate the effects of advanced oxidation protein products (AOPP) in type 2 diabetic ocular muscles palsy (DOMP). Methods 58 DOMP patients and 50 type 2 diabetes patients were included in the research. Hemoglobin A1c (HbA1c), blood glucose (FPG), fasting insulin (FINS) and triglycerides (TG), total cholesterol (TC), high-density lipoprotein (HDL), low-density lipoprotein (LDL) were measured and recorded. Homeostasis model assessment was performed to evaluate the status of insulin resistance (HOMA-IR), basal insulin secretion (HOMA-β) and the insulin sensitivity index (ISI). Serum AOPP was measured by enzyme linked immunosorbent assay. Unconditional logistic regression model was used to evaluate the influencing factors of DOMP. Results The DOMP group showed higher levels of plasma AOPP, TG, LDL, FPG, FINS, HbA1c and HOMA-IR, but lower levels of HDL, HOMA-β and ISI than those of the T2DM group. Unconditional logistic regression analysis revealed that AOPP was an independent risk factors for DOMP (OR =3.01, P = 0.002). Conclusion AOPP may be involved in the pathogenesis of DOMP. AOPP could be a useful indicator for monitoring the development of DOMP and for evaluating its severity.
RESUMO
BACKGROUND: Puerarin, the main effective component of Chinese herb, Radix puerariae, is isoflavone monomer, which can counteract learning and memory impairment induced by scopolamine or D-galactose etc.OBJECTIVE: To investigate the protective effects of puerarin on β-amYloid peptide-induced learning and memory impairment of model mouse of dementia and the changes of superoxide dismutase activity and malondialdhehyde content in brain and blood.DESIGN: Randomized controlled trailSETTING: Department of Pharmacology, Capital University of MedicalSciencesMATERIALS: The experiment was conducted in Departmentof Pharmacology of Capital University of Medical Sciences from March to June 2002.A total of 40 ICR mice were selected and randomly divided into 4 groups:pseudooperation group, dementia model group, puerarin 25 mg/kg group and puerarin 50 mg/kg group, with 10 in each group.METHODS: ①Model preparation: After anaesthesia with pentobarbital sodium, single intraventricular injection of 3 μL β-amyloid peptide was conducted from right side on each mouse in dementia model group, puerarin 25 mg/kg group and puerarin 50 mg/kg group under aseptic manipulation. The same operation was carried out on the mouse in pseudooperation group but without injection of β-amyloid peptide. ②Giving medicine:10 mL/kg physiological saline was intraperitoneally injected into the mouse in pseudooperation group and model group; 25 mL/kg puerarin was intraperitoneally injected to the mouse in 25 mg/kg puerarin group; 50 mL/kg puerarin was intraperitoneally injected to the mouse in 50 mg/kg puerarin group.The medicines were given to each group from the day of model preparation on and behavioral test was carried out 12 days later. ③ Morris water maze examination was used to detect learning and memory ability of the mice.Time for finding the platform (escape latency) in 2 minutes, swimming distance, original angle and search strategy were recorded as learning results.④When the above experiment was finished, anaesthesia with ether was applied to the mice and blood was collected from the orbit to prepare serum.After that, the mice were put to death by decapitation and the tissue of right-brain of the mice were rapidly took out to prepare cerebral homogenate in ice bath, then superoxide dismutase activity and malondialdhehyde content were determined in brain and serum.MAIN OUTCOME MEASURES: ①Escape latency, swimming distance,search strategy and original angle for the mouse in each group to reach the latform. ②Superoxide dismutase activity and malondialdhehyde content in brain and blood of the mouse in each group.RESULTS: All the 40 mice were involved in result analysis. ① Escape latency and swimming distance were shortened in puerarin 25 mg/kg and 50 mg/kg groups (P ＜ 0.05-0.01). The results of search strategy and original angle indicated that as the number of training days increased, the frequency of randomization+magin strategy gradually decreased; The decreasing rates and extents in pseudooperation group and puerarin 25 mg/kg and 50 mg/kg puerarin were more rapid than that in dementia model group,meanwhile, the increasing rates and extents of frequency of tendency+directness strategy in these groups were more rapid than that in dementia model group. There was no significant difference in original angle between groups (P ＞ 0.05). ② The content of superoxide dismutase increased and that of malondialdhehyde decreased in brain and blood of the model mouse in puerarin 25 mg/kg group andpuerarin 50mg/kg group (P ＜ 0.05 -0.01).CONCLUSION: Puerarin can counteract the neurotoxicity of β-amyloid peptide, which improves learning and memory of model mouse. It is not relevant to the dosage but probably related with elimination of cerebral free radical and improvement of antioxidation activity.

RESUMO
The effects of ginseng saponins on platelet aggregation, cyclic AMP and cyclic GMP level in platelets were studied. Ginseng saponins was found to be a potent inhibitor of platelet aggregation induced by arachidonic acid ( AA ) , ADP and thrombin in vitro and in vivo. The concentrations of ginseng saponins producing 50% inhibition of platelet aggregation induced by 0.55HM AA, 1.8-3.5uM ADP and 0.6-0.7 NIH u/ml of thrombin were 0.44, 1.20 and 1.32 mg/ml respectively. The inhibition % of aggregation induced by AA and ADP in vivo from 2-30min after iv administration of ginseng saponins ( 80 mg/kg) were 99-30.44 and 80.7-40.7, respectively. Also, cyclic AMP and cyclic GMP level in platelets were determined. It was observed that ginseng saponins significantly increased cyclic AMP level in platelets in a dose-dependent manner. But ginseng saponins did not affect cyclic GMP level in platelets. Our results indicate that the inhibition of ginseng saponins on platelet aggregation may be associated with an increase in cyclic AMP level.
RESUMO
jiaogulan ( Gynostemma pentaphyllum) extract (0.25~2g/L. final concentration) obviously inhibited the platelet aggregation & TXB2 release induced by arachidonic acid ( AA ) in vitro, and the ID50 of inhibiting TXB2 release was 0.28g/L. With the dose of 35mg/kg i. v. , it evidently inhibited platelet aggregation at 10 & 20 min after injection, and also markedly decreased TXB2 released by platelets during 10~40 min after injection, especialy within 20 min. Jiaogulan extract (0.25~4g/L) did not influence 6-keto-PGF1? release of aorta thoracalis of rabbits in vitro. Enzyme immunoassay was used to measure the content of TXB2 & 6-keto-PGF1? in the experiments. The above results suggest that Jiaogulan extract may decrease TXA2/PGI2 ratio.
