Cardiopulmonary arrest is one of the most critical situations,posing a serious threat to life.With the development of medical technology, the rate of return of spontaneous circulation after cardiac arrest has been improved.However, many children suffer from multiple organ dysfunction because of the long hypoxia time from cardioplumonary arrest, so the rate of long-term survival is relatively low and the long-term outcome is still not satisfactory.Therefore, how to make cardiopulmonary resuscitation more effective is the focus of current research.This article reviews the related factors that affect the outcome of resuscitation, providing references for the treatment of cardiopulmonary arrest in children.

Background One of the important machanisms of all trans retinoic acid (ATRA) is to regulate the expression of connexin (Cx) gene.ATRA inhibits the proliferation and differentiation of retinoblastoma (RB) cells,which is related to Cx43.However,the control site of ATRA and its effect on RB tumor in vivo have not been identified.Objective This study was to investigate the effect of ATRA on Cx43 expression in RB cells and its approach mechanisms.Methods ATRA solution of 1 × 10 2 mol/L was prepared with ethanol and formulated into 1×10 5,1×10-6and 1 × 10 7 mol/L of solution with culture medium further.Human RB cell line (HXO-RB44) was cultured and treated with different concentrations of ATRA for 2,4 and 6 days,respectively.The expressions of Cx43 protein and mRNA in RB cells were detected by Western blot and reverse transcription PCR (RT-PCR),respectively.RB models were established by injecting HXO-RB44 cell suspension into anterior chamber in the right eyes of 15 athymic mice.Eleven successful models were divided into the blank control group,negative control group and 1 × 10-5 mol/L ATRA group,and 0.5％ normal saline solution with athymic or 1 ×10-5 mol/L ATRA solution was injected into the anterior chamber in the negative control group and 1 × 10-5 mol/L ATRA group in the 3-day interval for 3 weeks.The model eyes were examined under the slit lamp microscope.The eyeballs were extracted at the end of the experiment for hematoxylin and eosin staining.Results Western blot assay showed that the absorbance values of Cx43 protein (ACx43/AGAPDH) were increased gradually as time lapse of ATRA treatment among the groups (Ftime =71.31,P =0.00; Fgroup =7.66,P =0.00).The expressions of Cx43 protein were significantly higher in the 1 × 10 5 mol/L ATRA group after 2 days,1 × 10-6 mol/L ATRA group after 4 days,1 × 10-7 mol/L ATRA group after 6 days than those in the blank control group at various time points (t =3.34,P＜0.01 ;t =2.33,P＜0.05;t =3.12,P＜ 0.01).RT-PCR showed that the absorbance values of Cx43 mRNA (ACx43mRXA/Aβ-actin) were significantly enhanced as the prolong of treatment time of ATRT among the groups (Ftime =90.90,P =0.00 ; Fgroup =6.86,P =0.00).The expressions of Cx43 mRNA were significantly higher in the 1 × 10-5 mol/L ATRA group after 2 days,1 × 10 6 mol/L ATRA group and 1 ×10-7 mol/L ATRA group after 4 days than those in the blank control group at various time points (t=3.57,P＜0.01 ;t=6.31,P＜0.01 ;t=2.22,P＜0.05).RB models were successfully created in 11 eyes on the 6-9 days following the intrachamber injection of RB cell suspension.The RB cells were filled with chamber in the blank control group 20 days after injection,and RB only occupied half of the anterior chamber in the 1 × 10-5 mol/L ATRA group.Histopathological examination exhibited that the RB cells were seen in the anterior and posterior chamber as well as vitreous in the blank control group,however,the cells were only found in the anterior chamber in the 1 × 10 5 mol/L ATRA group.Conclusions ATRA can inhibit the growth of RB in vitro and in vivo by inducing the expression of Cx43 gene in transcription process.

Objective To evaluate left atrial function by velocity vector imaging (VVI) in patients with rheumatic mitral stenosis(RMS). Methods Thirty eight patients with RMS and 42 normal controls were studied with VVI analysis software. Peak systolic strain (S), systolic strain rate(SRs), early diastolic strain rate(SRe) and late diastolic strain rate(SRa) of each left atrial segments were measured,and also the SRa peak time delay(Td-SRa). Results Comparing to the controls group, the S, SRs and SRe of all segments were significantly lower(P<0.05). Except the base latero-aorta's SRa, the other segments' SRa were lower (P<0.05). In patients with atrial fibrillation(AF),56% segments had no SRa,and 18.6% had irregular low amplitude movement at late diastole, while 25.4% had discernible positive peak. The base and middle inferior SRa of patients with AF were lower (P<0.05 ) than those of the patients with sinus rhythm. While the Td-SRa of patients was longer than that of control group,especially what of the patients with AF. Conclusions The segmental and globe left atrial function of patients with RMS can be evaluated with VVI.

Objective To investigate the effects of nicergoline on the treatment of posterior circulation ischemia vertigo (PCIV).Methods A total of 87 patients with PCIV were randomly treated either with nicergoline (45 cases) or betahistine (42 eases).Dizziness assessment rating scale (DARS) and dizziness handicap inventory (DHI) were used to evaluate the changes of manifestations before treatment,after 7 days and 8 weeks treatment with nicergoline,meanwhile transcranial Doppler ultrasound (TCD) and brainstem auditory evoked potential (BAEP) were observed to assess the effects.Results After 7 days of treatment,the scores of DARS and DHI were decreased significantly in nicergoline group (DARS:15.6±2.1 ; DHI:38.3± 11.4) and control group (DARS:14.3±4.4; DHI:39.5±14.7) compared with the scores before treatment (DARS:24.9±7.3,22.5 ±9.7; DHI:55.8±19.7,57.5±19.3) (all P＜ 0.05),and the treatment efficiency was 71.1％ (32/45),61.9％ (26/42).After 8 weeks of treatment,the scores of DARS and DHI were also decreased significantly in nicergoline group (DARS:8.9 ±3.9; DHI:26.3± 12.8) and control group (DARS:9.9±4.7; DHI:35.8±13.1) compared with the scores before treatment (all P＜ 0.05),and the treatment efficiency was 93.3％ (42/45),78.6％ (33/42).There was significantly differences in the scores of DHI and treatment efficiency between the two groups at 8 weeks (t =2.169,P＜ 0.05,and x2=3.98,P＜ 0.05),but no differences at 7 days (both P＞ 0.05).In consistent with the remission of the clinical symptoms,nicergoline group significantly recovered from both low blood diffusion in the verbal-basal artery system and extended peak latency(PL) and inter peak latency(IPL) in the auditory pathway examined by TCD and BAEP individually at 8 weeks,especially in the upper part of the brainstem (P＜0.05).Conclusions Nicergoline is very effective in the treatment of PCIV and could alleviate the subclinical ischemia to get long time benefits.
