Objective To compare efficacy and side effects of intravenous versus oral indomethacin treatment for symptomatic patent ductus arteriosus (PDA) in preterm infants.Methods Fourty-nine preterm infants were reviewed retrospectively who were diagnosed as having symptomatic PDA confirmed by echocardiography.According to the using type and approach that were divided into 2 groups (intravenous group,n=21;oral group,n=28) and their doses and intervals were same.The rates of ductal closure and side effects were compared in 2 groups.Results There were no significantly different between 2 groups in single ductal closure and complicating other diseases. Soon closure of intravenous group was higher significantly than oral group [61.9 %(13/21) vs 28.6 %(8/28),P

Objective To study the relationship between clinical diagnosis and children ventricular premature beat(VPB) electrocardiogram location and morph.Methods Both organic heart disease and without organic heart disease relationship with 109 cases of children ventricular premature beat electrocardiogram location and morph were retrospectively analyzed.Results Children ventricular premature beat location shows that organic heart disease mostly results from left ventricle, without organic heart disease often comes from right ventricle. There was significant difference between above two groups (? 2=37.25 P

Objective To investigate the changes and clinical significances of the chemokines of interferon-?-inducible protein-10(IP-10),monocyte chemoattractant protein-1(MCP-1) and growth-related oncogene-?(Gro-?) involved in pathagenesis of Kawasaki disease(KD) and HenochSchonlein purpura(HSP).Methods The chemokines production of IP-10,MCP-1 and Gro-? were assayed by ELISA in 15 patients with KD,12 patients with HSP and 10 healthy children.Results The plasma levels of IP-10 and MCP-1 were markedly elevated in KD group [(394.2?176.4)and(420.5?163.4)ng?L-1]compared with HSP group[(94.8?66.4)and(109.2?76.6)ng?L-1] and the control group [(76.4?46.5)and(87.7?47.8)ng?L-1](all P0.05),as well as Gro-? between the three groups.Conclusion Monocyte may enhance the immune damage in KD pathogenesis,and the levels of IP-10,MCP-1 may be important indexes for KD.Neutrophil may be not involved in pathogenesis of HSP and KD.

Emerging data indicated that HCV subverts the antiviral activity of interferon (IF); however,whether HCV core protein contributes to the process remains controversial. In the present study, we examined the effect of HCV core protein on interferon-induced antiviral gene expression and whether the effect is involved in the activation and negative regulation of the Jak/STAT signaling pathway. Our results showed that, following treatment with IFN-α, the transcription of PKR, MxA and 2'-5'OAS were down-regulated in HepG2 cells expressing the core protein. In the presence of HCV core protein,ISRE-dependent luciferase activity also decreased. Further study indicated that the core protein could inhibit the tyrosine phosphorylation of STAT1, whereas the level of STAT1 expression was unchanged.Accordingly, SOCS3, the negative regulator of the Jak/STAT pathway, was induced by HCV core protein. These results suggests that HCV core protein may interfere with the expression of some interferon-induced antiviral genes by inhibiting STAT1 phosphorylation and induction of SOCS3.

Objective To discuss the short-term currative effect of horizontal osteotomy across injured vertebral forⅤdegree old frac-ture-dislocations of thoracolumbar spine.Methods The data of 4 patients who received horizontal osteotomy across injured vertebral internal fixation in our hospital from April 2010 to October 2012 were retrospectively analyzed,of which 1 case with T8-9 fracture dislocation,2 cases with T10-11 fracture dislocation,1 case with T11-12 fracture dislocation.The Franke1 classification of all patients were grade A.Results All 4 cases were achieved completely fracture reduction and followed-up for 2-14 months(an average of 7.4 months),who could get sitting posi-tion with the support of brace 1 week after operation.The postoperative follow-up indicated that all 4 cases got fusion,but there was no improve-ment for Franke1 classification.Conclusion The method of horizontal osteotomy across injured vertebral forⅤdegree old fracture-dislocations of thoracolumbar spine has good short-term clinical effect,with the advantages of shorter operation time,less bleeding and good reduction effect.

According to the 2010 Chinese pharmacopeia, salt processed and charcoal processed Eucommiae Cortex were pre- pared. HPLC-DAD analysis of the content of the bark and leaf of Eucommiae Cortex showed that the bark of Eucommiae Cortex mainly contained lignans such as pinoresinol glucose and iridoid including genipin, geniposide, geniposidic acid, while the leaf of Eucommiae Cortex consisted of flavonoids such as quercetin and phenolic compound such as chlorogenic acid. The content of pinoresinol diglucoside in the bark of Eucommiae Cortex was about 18 times more than that in the leaf of Eucommiae Cortex. The content of pinoresinol diglucoside in salted and charcoal processed Eucommiae Cortex decreased approximately by 30% and 85%, respectively. The content of genipin, geniposide and geniposidic acid in the bark of Eucommiae Cortex was about 3 times, 23 times, 28 times more than that in the leaf of Eucommiae Cortex. The content of genipin, geniposide and geniposidic acid in salted Eucommiae Cortex were reduced by 25%, 40% and 40%, respectively. The content of genipin, geniposide and geniposidic acid in charcoal processed Eucommiae Cortex were reduced by 98%, 70%, 70%, respectively. The content of caffeic acid in bark of Eucommiae Cortex was about 3 times more than that in the leaf of Eucommiae Cortex. The content of caffeic acid was decreased by about 50% in the salted Eucommiae Cortex. While the content of caffeic acid in charcoal processed Eucommiae Cortex was decreased approximately 75%; the content of chlorogenic acid in bark of Eucommiae Cortex was about 1/6 of that in the leaf of Eucommiae Cortex. The content of chlorogenic acid in salted and charcoal processed Eucommiae Cortex decreased by 40% and 75%, respectively; the content of quercetin in bark of Eucommiae Cortex was only 1/40 of that in the leaf of Eucommiae Cortex. The content of quercetin in salted and charcoal processed Eucommiae Cortex were reduced by 60% and 50%, respectively.
