Objective To investigate the accuracy of computer-assisted interpretation(CAI)in the diagnosis of pediatric critical arrhythmia,and to establish Logistic regression model to evaluate the main risk factors of CAI error.Methods 1147 cases of arrhythmia patients were divided into heart disease(HD)and nonheart disease group(NHD).Candidate risk factors were chosen,from which the vailables statistically significant were entered for logistic regression analysis.Results CAI error rate of HD group and NHD group were 24.9%and 11.4%,showing a significant difference(P＜0.05).Age,underlying diseases,the number of CAI diagnosis entries were the risk factors.Conclusion CAI error pattern was different among HD group and the NHD group.Higher awareness for CAI error risk factors and CAI technology improvement are critical for a lower CAI error rate.

Objective To investigate the changes of tumor necrosis factor- ?(TNF- ?) and souble intercellular adhesion molecule - 1 (sICAM - 1) in serum and cerebrospinal fluid (CSF) in children with viral encephalitis (VE) before and after treatment,and to explore the pathogenesis of the cytokins in VE. Methods The levels of TNF - ? and sICAM - 1 in serum and CSF were determined before and after treatment using EL1SA in 38 children who were admitted with VE, and 20 children as normal controls. Results The levels of TNF- ? and sICAM - 1 in serum and CSF before treatment were obviously higher than those of control group,and the difference was significant(P 0. 05), but the serum and CSF TNF - ? and sICAM - 1 levels in SVE group were higher than those of control group(P

Purpose The glucosamine and chondroitin compound tablets were prepared. The anti-inflammatory and analgesic effects of glucosamine and chondrotin compound tablets were investigated. Methods The proportion of glucosamine and chondroitin was 5:4 to prepare compound tablets. The anti-inflammatory effect was investigated with carrageen-induced rats paw edema and cotton granuloma in rats. The analgesic effect was investigated using the pain models of mice which were induced by 0.6% acetic acid. Results Compared with control group the degree of paw edema in the low, middle and high dose group was decreased ( P < 0.05). Fourtreatment groups compared with control group respectively at the weight of granuloma were also markedly reduced ( P < 0.05) and the writhing number of mice induced by acetic acid was decreased ( P < 0.05 ) . Conclusion glucosamine and chondroitin compound tablets have anti-inflammatory effect and analgesic effect on models induced by acetic acid.

Objective To evaluate the therapeutic effect of esophageal intraluminal stents with 125I seeds based on survival time and quality of life (QOL) of patients with advanced esophageal cancer.Methods A total of 37 patients with advanced esophageal cancer who underwent placement of esophageal 125I irradiation stent were followed up.The QOL was evaluated by QLQ-C30 and QLQ-OES18 questionnaires before the procedure, and 1 week and 3 months after.Results The mean survival time of 37 patients was 28 weeks, with 3-month and 6-month survival rates at 94.6% (35/37) and 51.4% (19/37), respectively.Compared with the baseline, the scores of emotional functioning(EF), cognitive functioning(CF),global quality of life(QL), fatigue(FA), pain(PA), financial difficulties(FI) and pain of QLQ-OES18(OESPA) assessed 1 week after stent placement increased (P<0.05) significantly and dysphapia of QLQ-OES18(OESDYS), eating of QLQ-OES18(OESEAT), trouble swallowing saliva of QLQ-OES18(OESSV) and choked when swallowing of QLQ-OES18(OESCH) decreased significantly (P<0.05).At 3 months after stent placement, the scores of FI increased significantly (P<0.05), and those of nausea or vomiting (NV), OESDYS,OESEAT, OESSV and OESCH decreased significantly (P<0.05).The scores of FI,OESDYS, OESCH, role functioning(RF), EF,CF,FA and OESPA at 3 months were significantly different from those at 1 week after the procedure (P<0.05).Other variables at 1 week and 3 months after the procedure were not different from those before (P>0.05).Conclusion Implantation of 125I seeds combined with esophageal intraluminal stents may prolong survival time and improve QOL of patients with advanced esophageal cancer.

OBJECTIVETo observe mainfestations of syndrome and biochemical indices of hypertensive model rats with excessive accumulation of phlegm-dampness syndrome (EAPDS), and to explore its possible pathological mechanism.

METHODSEAPDS rat model was prepared in 50 Wistar rats by feeding with high fat forage. Meanwhile, a normal control group consisting of 10 Wistar rats was set up by feeding with normal forage. After 25-week continuous feeding, 22 rats with body weight (BW) and blood pressure (BP) exceeding 25% those of the control group were selected as a model group. BW, BP, blood lipids, and related serological indicators were detected in all rats. Morphological changes of target organs were observed. mRNA expression levels of leptin receptor (LepR), Janus kinase2 (Jak2), signal transducer and activator of transcription 3 (Stat3), suppressor of cytokine signaling-3 (Socs3), angiotensin II receptor type 1 (AT1), angiotensin II receptor type 2 (AT2), phosphatidylinositol 3 kinase (P13K), serine threonine kinase (Akt), nuclear factor of kappa B (NF-κBp65), inhibitor of nuclear factor kappa-B kinase α (IKKα), NF-kappa-B inhibitor β (lKKβ), NF-kappa-B inhibitor α (IKBα), and AMP-activated protein kinase (AMPK) were detected by quantitative real-time PCR (qPCR). Expression levels of AT1 and LepR in aorta were detected by immunohistochemical assay and Western blot respectively.

RESULTSCompared with the control group, BW, BP, and blood lipids increased; serum levels of leptin (Lep) , Ang II, Hcy, ET-1, TNF-α, IL-6, and p2-MG increased, but NO decreased in the model group (P < 0.05, P < 0.01). Aortal endothelial injury and smooth muscle cell proliferation occurred in the model group, accompanied with heart and renal injury. Compared with the control group, mRNA expression levels of LepR, Jak2, Stat3, Socs3, AT1 , PI3K, Akt, NF-κB p65, IKKβ, IKBα, and AMPK in aorta were up-regulated significantly (P < 0.05), while the expression of IKKa decreased (P < 0.05). Immunohistochem- ical staining showed, brownish yellow deposit of AT1 and LepR was obviously increased, with more extensively positive distribution. Western blot results showed, as compared with the control group, protein expression levels of AT1 and LepR obviously increased in the model group (P < 0.05).

CONCLUSIONSModel rats exhibited typical syndromes of EAPDS. They put up weight with fat abdomen, gloomy hair, poor appetite, hypersomnia, lowered activities , reduced food intake, loose stool, dark red tongue, white tongue with white, thick, greasy fur. Lep could be taken as one of objective indicators for evaluating hypertension rat model with EAPDS.
