Objective To explore the clinical characteristics and treatment of paroxysmal supraventricular tachycardia (PSVT) in children. Methods The clinical data of 67 children with PSVT were analyzed retrospectively, and the therapeutic effects of different treatments were compared. Results The clinical manifestations of infants were paleness, shortness of breath, irritability and sweating, and children showed chest tightness, palpitations, abdominal discomfort and fatigue. The curative effect of electric cardioversion, transesophageal atrial pacing, physical therapy, and drug therapy was statistically different (P<0.05), The different cardioversion rates of them were observed for the treatment of paroxysmal supraventricular tachycardia. The cardioversion rate of transesophageal atrial pacing, was the highest, and the rate of physical therapy was the lowest. There was no significant difference in the cardioversion rate between propafenone, digoxin and amiodarone. Conclusion The clinical manifestations of PSVT in infants are atypical and easily to be ignored. There are many methods for treatment of PSVT. The vagus nerve can be stimulated first, and, if no response, either drugs or electric cardioversion and transesophageal atrial pacing can be used. The cardioversion rate of transesophageal atrial pacing is higher. The drug effectiveness for the treatment of PSVT depends on many factors, and our choice of medication varies from person to person.

BACKGROUND: Looking for effective measures to ensure the survival of the implanted stem cells against ischemia-induced hypoxia becomes the major concern in the research of cell transplantation therapy for cerebral infarction.OBJECTIVE: To study the effects of human Persephin gene transfer on hypoxia-induced apoptosis of neural stem cells.DESTGN: A randomized controlled basic study on cells.SETTTNG: Department of Neurology, the Second Affiliated Hospital of Sun Yat-sen University.MATERTALS: This study was completed in the Lin Baixing Laboratory Center of the Second Affiliated Hospital of Sun Yat-sen University from July to December in 2006. Recombinant adenovirus pAdCMV persephin was constructed in our lab. C17.2 neural stem cells were kindly provided by Prof. Snyder, Harvard Medical University, USA. Trypsin and DMEM/F12 were purchased from Gibco Company (USA), fetal bovine serum (FBS) from Sijiqing Biological Engineering Materials Co. Ltd (Hangzhou, China); Poly-lysine from Sigma Company (USA), TUNEL assay kit and FuGENE kit from Roche Molecular Biochemicals Company (Swiss), and S-P immunohistochemical detection kit and DAB reaction kit from Mycine Biological Engineering Company (Fujian). Rat anti-human monoclonal Nestin antibody and rabbit anti-human polyclonal persephin antibody were manufactured by Santa Cruz Company (USA), and persephin anti-senseoligodeoxynucleotide (ODN) was synthesized by Shanghai Biological Engineering Company.METHODS: ① Interventions: C17.2 neural stem cells cultured in vitro were infected by recombinant adenovirus containing persephin gene, and they were divided into four groups: blank control group (Group A, in which the C17.2 neural stem cells were not treated with hypoxia), hypoxic group [Group B, in which the cells were cultured at 37 ℃ in anaerobic incubation containing N2 (0.95 in volume fraction) and CO2 (0.05 in volume fraction)], hypoxia + pAdCMV persephin infection group [Group C, where the cells were cultured under the conditions as in group B after pAdCMV persephin infection for 48 hours], and hypoxia + pAdCMV persephin infection + anti-sense persephin ODN group (Group D, where the cells were infected by pAdCMV persephin and anti-sense persephin ODN. ② Evaluation: The expression of Persephin protein was analyzed using Western blotting; Apoptotic index was detected with terminal deoxynucleotidyl transferase-mediated deoxyuridine triphosphate nick end-labeling (TUNEL) assay; The changes of apoptotic rate was determined with flow cytometry.MAIN OUTCOME MEASURES: Expression of Persephin protein; Apoptotic index; Apoptotic rate.RESULTS: ① Expression of Persephin protein: A specific band (relative molecular mass of 24 000) was detected by Western blotting in pAdCMV persephin infected cells, suggesting the successful expression of persephin gene.Interestingly, the cells infected with both pAdCMV persephin and anti-sense persephin ODN also showed the specific band of about 24 000, but with much less density, indicating that anti-sense persephin ODN could effectively inhibit the expression of pAdCMV persephin. However, this band was not presented in the blank control groups. ② Apoptotic index:The apoptotic index in group C was significantly lower than those in groups B and D (P＜0.01), but still higher than that of group A (P＜0.01), suggesting that persephin gene transfer could attenuate apoptosis to some extent. ③ Apoptotic rate: The apoptotic rate in groups B and D were obviously higher than that in group A (P ＜ 0.01), and it was lower in group C than in groups B and D (P＜0.01).CONCLUSION:Recombinant adenovirus can efficiently mediate Persephin gene transfer into C17.2 neural stem cells,resulting in high expression of the exogenous Persephin in vitro, which effectively reduces C17.2 neural stem cell apoptosis induced by hypoxia.

Objective To investigate the relationship between the single nucleotide polymorphism of aminoimidazole carbexamide ribonucleotide transformylase gene and the efficacy and toxicity of methotrexate treatment in rheumatoid arthritis. Methods Total of 359 patients with RA were divided into mono-therapy with MTX group, combination therapy with other DMARDs group and other DMARDs combination with no MTX treatment group. The clinical and laboratory measurements were evaluated before therapy and 12, 24 weeks after therapy. Efficacy (evaluated by ACR20) and side effects of the drugs were also assessed. Real-time fluorescent quantitative PCR was conducted to test ATIC 347C/G mutation in RA patients and 340 healthy controls. Results There was no statistical significant difference in 347 CC, CG, GG between RA patients and healthy controls. In the MTX mono-therapy group (n=107), 72% (n=77) there was no statistical significant difference in 347CC, CG, GG between patients with good response and patients without efficacy. 32.7%(n=35) of these patients experienced adverse drug reactions. The ATIC G allele carriers (22.4%) experienced a greater frequency of side effects than the CC carriers (OR=2.672, 95%CI, 1.27～5.59, P<0.05). In MTX combined with other DMARDs group (n=128) and other DMARDs combination without MTX group (n=90), the polymorphism in the ATIC gene was not associated with good clinical response and adverse events (P>0.05). Conclusion There is no statistical significant difference between RA and healthy controls in the ATIC347 gene. Polymorphism in the ATIC gene is not associated with clinical response to MTX treatment, but the ATIC347 G allele is associated with MTX toxicity. It maybe used to predict the adverse drug reactions of patients who take MTX.

OBJECTIVETo establish the quality standard of Entadae Semen, and provide scientific basis for its quality control.

METHODTLC and HPLC were used for qualitative identification and quantitative analysis of phaseoloidin and entadamide A-O-β-D-glucopyranoside in Entadae Semen. The test of water content, ash and ethanol-soluble extractives of Entadae Semen was carried out according to the methods recorded in appendix of Chinese Pharmacopeia (2010 edition).
