Objective To explore the value of temporary cardiac pacemaker therapy on children with Adam-Stoke syndrome(ASS).Methods Nine children with ASS was implanted the emporary cardiac pacemaker under X-ray or blinding inserted beside bed.Results Seven children was successfully implanted the temporary cardiac pacemaker within 1-2 d of ASS attack,and two children was successfully implanted at 10 d and 20 d after ASS attack, respectively. Five patients was cured, two children was died, and two children was implanted the permanent cardiac pacemaker. During pacing, two patients had the electrode shifted,and one patient had the cardiac murmur,and one patient had the local skin infected.Conclusion Temporary cardiac pacemaker can successfully treat children with ASS attack;the earlier the implantation,the better the prognosis.

Objective To investigate the dose- and time-effects of astragaloside Ⅳ(XGA) on collagen of myocardial fibroblasts in rats.Methods The myocardial fibroblasts of rats were separated by collagenase and trypsinase digestive method,and the cell culture system was established. After XGA in different concentrations and at different time points was administered in fibroblast culture systems,the mRNA expression levels of collagen,matrix metalloproteinases(MMP)-1,-2,-9,tissue inhibitor of metalloproteinase(TIMP)-1 and -2 were measured with reverse transcription-polymerase chain reaction(RT-PCR) test.Results After XGA administration with different doses and at different time points was adminstered,the gel electrophoresis product of RT-PCR in fibroblast culture system expressed the mRNA of type Ⅰ,Ⅲ and Ⅳ collagens,MMP-1,-2,-9,TIMP-1 and -2;but the mRNA expression levels of type Ⅰ,Ⅲ and Ⅳ collagens,TIMP-1 and -2 decreased and the mRNA expression levels of MMP-1,-2,and -9 increased compared to those before XGA administration;the mRNA expression of type Ⅰ,Ⅲ and Ⅳ collagens,MMP-1,-2,-9,TIMP-1 and -2 decreased or increased gradually with the increase of doses and the prolonged time of XGA use.The mRNA expression levels of type Ⅰ,Ⅲ and Ⅳ collagens,TIMP-1 and -2 were negatively related to the doses and action times of XGA(r=-0.927 to -0.637 P= 0 to 0.024);and the mRNA expression levels of MMP-1,-2 and -9 were positively related to the doses and action times of XGA(r=0.672 to 0.962 P=0 to 0.034).Conclusion XGA can markedly reduce the collagen formation of myocardial fibroblasts in rats,and its mechanisms are related to the inhibiting of collagen synthesis and the increase of collagen degradation.

Hypertrophic cardiomyopathy(HCM)is the second commonest cardiac muscle disease affecting children and adolescents and is a leading cause of sudden death in young athletes. HCM is highly heterogeneous in pediatric population,and currently the precision diagnosis of the etiology of the disease faces enormous challenges. In addition,prospective and randomized controlled clinical studies in the diagnosis,treatment and prognosis of pediatric HCM are extremely rare. Evidence-based consensus or guidelines needs to be developed urgently for personalized risk assessment and treatment,as well as standardized family management and genetic counseling.

OBJECTIVETo evaluate the effect of Milkvetch Injection (MI) on cardiac function and hemodynamics in children with tetralogy of Fallot after radical operation.

METHODSThirty-two children with tetralogy of Fallot were divided into two groups, the 20 patients in the control group treated with conventional treatment and the 12 patients in the treated group treated with 15 ml of MI every 12 hrs for 7 days. The cardiac function and hemodynamic parameters were determined by echocardiography and thermodilution catheter inserted in pulmonary artery.

RESULTSPatients' cardiac function and hemodynamic parameters were improved significantly 1 hr after administering 15 ml of MI Injection, but restored to the level before medication in 2-4 hrs. Administering MI injection for successive 7 days could gradually improve patients' cardiac function and hemodynamic parameters after operation, and the improvement became more evident with the prolonging time of medication. The intubation time, intensive care unit duration and the time of intravenously administration of inotropic drugs in the treated group were significantly shorter than those in the control group (P < 0.01).

CONCLUSIONMI could significantly improve the hemodynamics and cardiac function, and shorten the recovery time in children with tetralogy of Fallot after radical operation.

The chemical vapor deposition grown graphene was transferred onto flexible polyethylene terephthalate surface to fabricate a graphene platform electrode ( GPE) , and gold nanoparticles ( AuNPs) were electrodeposited on GPE to form an AuNPs modified GPE ( AuNPs/GPE ) . The formation of AuNPs was confirmed by scanning electron microscopy ( SEM) , energy dispersive spectrometer ( EDS) , high-resolution transmission electron microscope ( HR-TEM) , X-ray diffraction ( XRD) and Raman spectra. On AuNPs/GPE, dopamine ( DA ) displayed a pair of well-defined redox peaks with highly enhanced peak currents compared with those on GPE. At detection potential of 0. 20 V, AuNPs/GPE sensor presented a wide linear range of 0. 1 μmol/L to 400. 0 μmol/L of DA with a detection limit of 3. 9 nmol/L (S/N=3). In addition, the proposed sensor allowed highly selective and sensitive, stable and fast amperometric sensing of DA.

Objective: To discuss the clinical efficacy of modified Tongqiao Huoxuetang combined with ‘Huiyang Jiuzhen’ in treating post-stroke cognitive impairment (PSCI) and its mechanisms in resisting inflammation and oxidant stress and ameliorating hemorheology. Method: One hundred and twenty-two patients were randomly divided into control group (61 cases) and observation group (61 cases) by random number table. Both groups got Donepezil tablets, 10 mg/time, 1 time/day, and Nicergoline tablets, 20 mg/time, 3 times/days. Patients in control group got ‘Huiyang Jiuzhen’, 1 time/day, 6 times/week. In addition to the therapy in control group, patients in observation group got modified Tongqiao Huoxuetang, 1 dose/day. And a course of treatment was 8 weeks. Before treatment and at the 4^th week and 8^th week after treatment, scores of mini-mental state examination (MMSE) and Montreal cognitive assessment (MoCA) were discussed. And activity of daily living scale (ADL), syndrome of blood stasis and cerebral collaterals were graded. And levels of Interleukin-6 (IL-6) before and after treatment, C-reactive protein (CRP), tumor necrosis factor-α (TNF-α), oxidized low density lipoprotein (Ox-LDL), superoxide dismutase (SOD), malondialdehyde (MDA), hemorheology were detected. Result: According to the rank sum test, the clinical efficacy in observation group was better than that in control group (Z=1.976, P<0.05). At the 4^th week and 8^th week after treatment, score of MMSE and MoCA were higher than that in control group (P<0.05), and the extent of the rise were more than that in control group (P<0.05). And scores of ADL and syndrome of blood stasis and cerebral collaterals were lower than those in control group (P<0.01). Levels of IL-6, TNF-α, CRP, DA and Ox-LDL were lower than those in control group (P<0.01), and level of SOD was higher than that in control group (P<0.01). Levels of whole blood viscosity (high-cut, low-cut), plasma viscosity, erythrocyte aggregation index, platelet aggregation, fibrinogen and erythrocyte sedimentation rate (ESR) were lower than those in control group (P<0.01). Conclusion: In addition to the routine therapy of western medicine, modified Tongqiao Huoxuetang combined with ‘Huiyangjiuzhen’ can improve patients cognitive function and daily life ability, have effects in resisting inflammation and oxidation and ameliorating hemorheology, and can promote the recovery of cognitive function.
