OBJECTIVEEctopic atrial tachycardia (EAT) is a common type of supraventricular tachycardia in pediatric population, and it can be resistant to antiarrhythmic drugs and lead to tachycardia induced cardiomyopathy (TIC) if not properly managed. This study assessed the clinical course and response to treatment of EAT in children.

METHODA retrospective review included 144 children at the First Hospital of Tsinghua University diagnosed with EAT from January 2009 to April 2014. The clinical detailed history, 12 lead ECG, 24-h Holter recording, echocardiography, response to therapy and follow-up were analyzed.

RESULTThe onset of EAT occurred at any age with a distribution with positive skewness, 57 children ≤1 years, 22 children > 1 - 3 years, 25 children > 3 - 6 years and 40 children ≥ 6 years of age. The percentages of the three tachycardia types were 36. 1% (n = 52) for incessant EAT, 52. 8% (n = 76) for paroxysmal EAT and 11. 1% (n = 16) for sporadic EAT, respectively. There were 115 patients received drug therapy in our hospital and in 72 cases the EAT was completely controlled. Antiarrhythmic therapy had been discontinued in 35 children with complete control. Normal sinus rhythm was observed by telemetry or Holter within 4 to 90 days and the mean duration of medical therapy was 310 days (range 15 to 608 days) in these children. The combination of sotalol and propafenone showed better effectiveness for control of children with EAT (54%, 41/76), compared with single sotalol (36%, 24/66) and the combination of amiodarone and metoprolol (30%, 7/23) (χ2 = 6. 296, P = 0. 043). Tachycardia type was able to predict the response to antiarrhythmic drugs for children with EAT, sporadic tachycardia had best control rate on pharmacological therapy compared with paroxysmal tachycardia and incessant tachycardia (94% (15/16) vs. 67% (42/63) vs. 42% (15/36), χ2 = 17. 925, P = 0. 000) . Acute success of radiofrequency ablation (RFA) in children who showed poor response to antiarrhythmic drugs was achieved in 45 of 49 (92%), ultimate success was achieved in 33 of 49 (67%). The incidence of TIC secondary to EAT was 18. 1% (n =26), and left ventricular ejection-fraction (LVEF) returned to normal in 23 children after successful control of EAT ((61 ± 4) % vs. (43 ± 5) %, t = - 10. 036, P = 0. 000). Side effects including abnormal thyroid function (in 3) and abnormal liver function (in 1) occurred in 4 (17%) of 23 children who received amiodarone and disappeared when amiodarone was discontinued.

CONCLUSIONEAT in children predominantly occurred in young infants and children. Incessant EAT comprised a great percentage. The combination of sotalol and propafenone provided the best results for control of children with EAT. RFA should be considered as a preferred treatment for older children who displayed poor response to medical therapy.

The apoptotic cell rate in transfected cells was 36.30%, as the control, untransfected cells was 11.53%.Moreover, the different stage of apoptotic cells could be distinguished by annexin V and propidium iodine stain.Conclusion:This supports a novel pathway of HCC cells were apoptotic itself via the CD95-CD95 ligand system without involvement of immune cells.

Objective To compare the influence of ziprasidone and paliperidone on PANSS scores,PRL and body weight of female patients with schizophrenia.Methods 140 female patients with schizophrenia were chosen,and they were randomly divided into group A (70 patients) with ziprasidone and group B (70 patients) with paliperidone.The clinical efficacy,PANSS score,PRL levels and body weight before and after treatment,and incidence of adverse effects were compared between the two groups.Results There was no significant difference in the clinical effects between the two groups (x2 =1.27,P ＞ 0.05).After treatment,the PANSS scores of both two groups were significantly better than those before treatment (t =2.78,3.31,3.06,3.50,2.90,3.38,3.17,3.62,all P ＜ 0.05).There was no significant difference in PANSS score after treatment between the two groups (t =1.08,1.20,0.97,0.88,all P ＞ 0.05).After treatment,the PRL level of group A was significantly higher than that before treatment (t =2.65,P ＜ 0.05).There was no significant difference in PRL level of group B between before and after treatment(t =1.24,P ＞ 0.05).There were no significant differences in the body weight between the two groups (t =1.10,0.97,0.88,all P ＞ 0.05).There was no significant difference in the incidence of adverse reactions between the two groups (x2 =1.03,P ＞ 0.05).Conclusion Ziprasidone and paliperidone in the treatment of female patients with schizophrenia has the same clinical effects and safety;but compared with paliperidone,ziprasidone in the treatment of female patients with schizo-phrenia can efficiently avoid the impact on the PRL levels of patients and reduce the risk of high serum PRL.

Objective To explore the impact of medication self-management module on treatment compli-ance and social function of patients with schizophrenia. Methods 66 inpatients with schizophrenia in their non-acute stage were randomly divided into training group(n=33) and control group(n=33). Both groups received the anti-psychotics therapy. Medication self-management module was only given to the training group for 8 weeks.All subjects were follow up for 6 months and were evaluated with self-made drug treatment compliance rating scale,self-made work ability rating scale, social disability screening schedule(SDSS). Results Treatment compliance,the total scores of SDSS of training group were significantly higher than that of control group after 8 weeks and 6 months: treatment compliance (χ~2=9.188,29.630, P < 0.01); the total scores of SDSS ((2.63±2.74) vs (5.27 ±3.05), (1.69±2.35) vs (4.91±3.06), P=0.000); work ability of training group was significantly higher than that of control group after 6 months (χ~2=19.443, P=0.000). Treatment compliance (χ~2=8.053, P=0. 018), the total scores of SDSS((2.63±2.74) vs (6.81±3.06), P=0.000) of training group after 8 week and 6 months were significantly higher than that of pretraining. Treatment compliance and work ability of both groups on 6 months follow up were significantly lower than that of 8 weeks (P < 0.01). Correlation analysis can-firmed that there was positive relation between the total scores of SDSS and treatment compliance, work ability on 6 months later. Conclusion Medication self-management module could significantly improve treatment compliance,social function and work ability of patients with schizophrenia.

Objective To investigate the changes and significance of serum inflammatory factors in coronary heart disease (CHD) patients with obstructive sleep apnea-hypopnea syndrome (OSAHS) ,and the treatment effects of continuous positive airway pressure (CPAP).Methods A total of 76 CHD patients in Renmin Hospital of Wuhan University from October 2007 to October 2008 were enrolled.Polysomnography (PSG) was performed in these CHD patients to identify if they were complicated by OSAHS.The levels of inflammatory factors including TNF-α, IL-6, high sensitive C-reactive protein (hs-CRP) in serum were determined in the CHD patients and 23 normal subjects.The CHD patients with mederate-severe OSAHS (AHI≥ 15 episodes/hour) were treated by Auto-CPAP for 3 months and all parameters above were measured again.Results There were 41/76 (53.9%) of CHD patients had mederate-severe OSAHS and were treated with CPAP.The levels of TNF-ct,IL-6 and hs-CRP were significantly higher in the CHD patients than those in the normal controls (all P <0.01) ,and were significantly higher in moderate-severe OSAHS patients than those in the non-OSAHS CHD patients.Auto-CPAP ventilation significantly decreased the levels of inflammatory factors in the CHD patients with moderate-severe OSAHS.Conclusions An obvious proinflammatory state is detected in CHD patients ,and is aggravated with OSAHS.CPAP is a useful treatment for CHD patients with mediate to severe OSAHS.
