The regulation mechanism of arecoline on rat hepatic CYP2E1 was studied in vivo. After oral administration of arecoline hydrobromide (AH; 4, 20 and 100 mg x kg(-1) x d(-1)) to rats for one week, the hepatic CYP2E1 mRNA level remained unchanged, but the hepatic CYP2E1 protein content was dose-dependently increased. Additionally, although the hepatic CYP2E1 activity was induced by AH treatment, the induction was attenuated with the increase in dosage. The results indicate that the effect of arecoline on rat hepaticdoes not involve transcriptional activation of the gene, but largely involves the stabilization of CYP2E1 protein against degradation or increased efficiency of CYP2E1 mRNA translation, and additionally involve the post- ranslational modification of CYP2E1 protein. Furthermore, the CYP2E1 response is fairly equal among the different species, the induction of rat hepatic CYP2E1 by arecoline suggests that there is a risk of metabolic interaction among the substrate drugs of CYP2E1 in betel-quid use human.

Objective To investigate safety and efficacy of dinoprostone suppositories(0.8 mm) used in cervical ripening and labor induction in women with term premature rupture of the membranes.Methods One hundred women of term monocyesis with premature rupture of the membranes,head presentation,bishop score less than 6(test group)and 180 women with intact fetal membranes(control group)were enrolled into this multicenter,prospective clinical study.The vaginal delivery system was inserted into the posterior foruix,and the patients were recumbent for 2 hours after insertion.The interval time from using dinoprostone suppositories to uterine contraction,to labor and delivery were recorded.The following index were also recorded and compared,including the mean inserted time of dinoprostone suppositories,fetal heart beat,meconium stained amniotic fluid,hyperstimulation of uterus and the other complications,mode of delivery,stage of labor,postpartum hemorrhage,status of neonates.Results Three cases intest group and 23 casesin control group weren't in labor within 24 hours.The rate of labor within 24 hours in test group was significant higher than that in control group(97.0% vs.87.2%,P<0.01).It was observed that 73 cases undergoing vaginal deliveries(75.3%,73/97)and 24 cases undergoing cesarean section dehveries(24.7%,24/97)in test group and 107 cases undergoing vaginal delivery(68.2%,107/157)and 50 cases undergoing cesarean section delivery(31.8%,50/157)in control group,when compared the rate of vaginal or cesarean section deliveries between two group,it didn't reach statistical difference (P >0. 05). It had no significant difference in the interval time from using dinoprostone suppositories to labor starting and the mean inserted time and the total labor time between two groups ( P > 0.05 ). The incidence of uterine tachysystole was 11.3% (11/97) in test group and 19. 1% (30/157) in control group (P>0. 05), which did not reach statistical difference (P>0. 05). There wasn't neonatal asphyxia in both groups. Conclusion It was safe and efficient to use dinoprostone suppositories for cervical ripening and induction of term pregnancy with premature rupture of the membranes, however, monitoring should be intensified.

Objective:To discuss the relationship between heart rate (HR) and heart rate differences (HRD) at different time points in head-up tilt test (HUTT) and the occurrence of postural tachycardia syndrome(POTS) in children and adolescents.Methods:A total of 217 children and adolescents diagnosed as POTS, who complained of syncope or presyncope, were chosen as POTS group (aged 6 to 16 years). During the same period, 73 healthy children and adolescents with matching gender and age were selected as control group.All subjects underwent HUTT from October 2000 to November 2019.Get HR (HR0, HR5, HR10) in baseline, HUTT 5 min and 10 min, HRD (HRD5, HRD10) of HR in HUTT 5 min and 10 min minus HR in baseline.Results:(1) HR5, HR10, HRD5, and HRD10 were higher in the POTS group than those in the control group( P<0.05). (2) Univariate Logistic regression: There was a correlation between HR5, HR10, HRD5, HRD10 and the risk of POTS( P<0.01). (3) Multivariable Logistic regression: For each additional unit of HRD5 and HRD10, the risk of POTS increased by 27% ( OR=1.27, 95% CI1.16 to 1.36) and 28% ( OR=1.28, 95% CI1.20 to 1.38). Conclusion:HR and HRD are related with the occurrence of POTS in children and adolescents, but HR and HRD at different time points of HUTT play the little role on the effect size of the occurrence of POTS.

Objective:To analyze the association between the types of response to head-up tilt test (HUTT) and levels of various vitamins in children and adolescents with orthostatic intolerance.Methods:Sixty-five cases of children and adolescents 35 males and 30 females aged 5-14 (10.5±2.0) years old who complained orthostatic intolerance symptoms, including syncope, dizziness, headache, and chest tightness, in Children′s Medical Center, the Se-cond Xiangya Hospital, Central South University between November 2018 and April 2019, were enrolled.By comprehensive history, physical examination, and necessary laboratory testing, heart, cerebrovascular and other system diseases were excluded.According to HUTT result, these patients were divided into 2 groups, namely negative HUTT group and positive HUTT group.The serum levels of vitamin A 1, B 1, B 2, B 6, B 9, B 12, C, and E were compared between the 2 groups.Continuous data were analyzed by conducting t-test and categorical data were analyzed by performing χ2 test. Results:(1) There were 32 cases (18 males and 14 females) in negative HUTT group and 33 cases (17 males and 16 females) in positive HUTT groups, with 28 cases of vaso vagal syncope and 5 cases of postural tachycardia syndrome.There were no significant differences in age, gender ratio, and body mass index between the negative HUTT group and positive HUTT group.(2) The serum level of vitamin B 1 of positive HUTT group was lower than that of negative HUTT group [(77.43±16.70) nmol/L vs.(88.56±18.98) nmol/L, t=-2.513, P<0.05], while the levels of vitamin A 1, B 2, B 6, B 9, B 12, C, and E had no significant differences between the two groups (all P>0.05). Conclusions:Patients with positive responses to HUTT relatively lacked vitamin B 1, suggesting the role of vitamin B 1 in the pathophysiological process of neurally mediated syncope.

Objective:To study the diagnostic efficacy and prognostic evaluation value of QT interval dispersion (QTd) in children and adolescents with cardioinhibitory vasovagal syncope (VVS-CI).Methods:From July 2010 to January 2020, 80 children and adolescents who received their first visit or admission to the Pediatric Syncope Clinic of The Second Xiangya Hospital of Central South University and definite diagnosed of VVS-CI due to syncope or presyncope were selected as the VVS-CI group, meanwhile, 80 children and adolescents who had physical examination in the hospital were selected as the control group.QT interval were measured by 12-lead electrocardiogram at the baseline.Results:(1) Comparison between the two groups: Compared with the control group, the VVS-CI group had a significantly lower heart rate ( P<0.05) and significantly longer QT interval, such as the maximum QT interval (QTmax), minimum QT interval (QTmin), QTd, corrected maximum QT interval (QTcmax) and corrected QT interval dispersion (QTcd) ( P<0.05). After follow-up 84 (45, 127) days, compared with the responsive group, the non-responsive group had a significantly longer QT interval, such as QTmax, QTd, QTcmax, corrected minimum QT interval (QTcmin)and QTcd ( P<0.05). (2) Diagnostic efficiency: QTmax, QTmin, QTd, QTcmax and QTcd had a certain diagnostic value in children and adolescents with VVS-CI ( P<0.001). QTd had the largest area under the curve (AUC) (0.914), and had a sensitivity of 86.30% and a specificity of 84.95% at the optimal cut-off value of 28.50 ms for VVS-CI diagnosis.(3) Prognostic evaluation value: QTmax, QTd, QTcmax, QTcmin, QTcd had an estimated value for the prognosis of VVS-CI in children and adolescents ( P<0.05 or 0.01). QTd had the largest AUC (0.906) and the best cut-off value was 34.50 ms, the sensitivity to predict response to VVS-CI intervention was 90.00%, and the specificity was 82.35%. Conclusion:QTd of electrocardiogram has a good estimation value in the diagnosis and prognosis of VVS-CI in children and adolescents.

Objective To explore the familial genetic characteristics of twins syncope in children.Methods Four pairs of twins with unexplained dizziness,headache,chest tightness,chest pain,pre-syncope and syncope were received head-up tilt test (HUTT) and family history of syncope were inquired.The age,gender,clinical manifestations were analyzed and the HUTT hemodynamic response were performed,and interviewed via telephone.Results The onset age of 4 pairs of twins ranged from 7 to 12 years old,less than 15 years,the median age of the first syncope episodes.Cause of syncope was primarily standing(4/5 cases),2 pairs had syncope positive family history.HUTT hemodynamic response type was mainly vasodepressor syncope (4/5 cases).HUTT result and hemodynamic response type were not completely consistent in the same twins.One case of the first twins was vasodepressor syncope and postural orthostatic tachycardia syndrome.One case of the second twins was vasodepressor syncope,while the other was negative.The third twins were vasodepressor syncope.The fourth twins were negative.HUTT results of the 4 twins were diverse,indicating that environment,psychological factors may get involved in syncope episodes.Conclusions The familial genetic factors of the children with syncope may play an important role in the young age group.Environment and psychological factors may be induce syncope attack.HUTT results of twins are diverse.HUTT result and hemodynamic response type can be inconsistent in the same twin.

Objective To analyse the 24 h ambulatory blood pressure monitoring(ABPM)character-istics and effect of health education in children with orthostatic hypertension (OHT)retrospectively.Methods A total of 19 children[1 1 males and 8 females with mean age of (1 1.26 ±2.16)years]who were outpa-tients or had been hospitalized in the Second Xiangya Hospital of Central South University due to unexplained syncope,presyncope,and finally diagnosed as OHT after head up tilt test(HUTT).HUTT and ABPM were reexamined at 12 ~190(47 ±48 )days after receiving health education (including psychological guidance, avoiding sudden changes in posture,increasing the amount of water,avoiding syncope inducement,etc). Results (1 )ABPM parameters:there were no significant differences of ABPM parameters before and after health education respectively(P ﹥0.05,respectively).(2)After the health education,HUTT 3 min diastolic pressure[(71.89 ±1.60)mmHg vs.(76.47 ±8.49)mmHg,1 mmHg =0.133 kPa,t =2.785,P ﹤0.05]and diastolic blood pressure change[(7.37 ±4.98)mmHg vs.(12.42 ±3.27)mmHg,t =3.560,P ﹤0.05]de-creased than those before health education.(3 )Blood pressure pattern changes:after the health education,“dipper blood pressure”increased and “non-dipper blood pressure”decreased[42.1 %(8 /19)vs.31.6%(6 /19)and 57.9%(1 1 /19)vs.68.4%(13 /19),χ2 =0.452,P ﹥0.05,respectively].(4)OHT cure rate:after health education,to review the HUTT,within 3 minutes in HUTT,blood pressure changes of 14 cases were normal range.The cure rate was 73.7%.Conclusion OHT children's blood type is given priority to with “non-dipper blood pressure”,and the ratio of“dipper blood pressure”increase and the HUTT 3 min di-astolic pressure and diastolic blood pressure change decrease after health education.It suggests that the health education of OHT children has a certain clinical effect.
