Objective To understand the cause of chest pain (precordium indisposition) in children and explore the thread of thought in its analysis.Methods Clinical data of 314 children with chest pain who visited the cardiovascular department for children of our hospital were collected and analyzed to study its causes.Results The cause could be attributed to organic cardiac diseases in 43 of 314 children (13.7%) with chest pain,to non-organic cardiac diseases in 108 (34.4%),to psychiatric-psychological factors in 60 (19.1%) and to unknown cause in 41 (13.1%).Average age of children with organic cardiac diseases was younger than that of children with other causes (P<0.05).Symptoms accompanied simultaneously in children with organic cardiac diseases were much more frequent significantly than those in them with non-organic cardiac chest pain and unknown causes (P<0.05).Conclusions Chest pain in children could be caused by a few causes,which was non-specific symptom for organic cardiac diseases,so, more should be taken into account in analyzing the cause of chest pain in children.

Objective To evaluate the effects of therapy with small volume of different fluids on renal blood flow in endotoxemia rats.Methods Thirty parthogen-free SD rats weighing 180-250 g were randomly divided into 5 groups (n = 6 each):group Ⅰ control; group Ⅱ LPS; group Ⅲ LPS + 7.5 % hypertonic saline (HS);group Ⅳ LPS + hydrozyethly starch (HES) 130/0.4 and groupⅤ LPS + hypertonic saline plus hydroxyethly starch (HS-HES) 40. The animals were anesthetized with intraperitoneal 3% pentobarbital 40 mg/kg. Left carotid artery was cannulated for BP and HR monitoring and fluid administration. In groupⅡ-Ⅴ LPS 1 mg/kg was administered via arterial cannula. In group Ⅲ, Ⅳ and V 4 ml/kg of 7.5% HS, HES 130/0.4 AND HS-HES 40 were administered via arterial cannula respectively at 30 min after LPS administration.In groupⅠ and Ⅱ normal saline 4 ml/kg was given insteadt. Renal blood flow was measured with Doppler ultrasound before LPS (T1 ,baseline), at 30 min after LPS (T2), 10, 30 and 60 min after fluid therapy (T3, T4, T5). The animals were then sacrificed and both kidneys were removed for microscopic examination with light microscope. Results Renal blood flow was significantly decreased and was significantly recovered to some extent by therapy with different fluids especially with HS-HES 40 in group Ⅴ. Conclusion Therapy with small volume of HS,HES or HS-HES could increase renal blood flow and inprove renal microcirculation especially HS-HES.

Objective To investigate the effect of simvastatin on gene expression of L-type calcium channels(LCCs) of myocardial cells in BALB/c mice infected by coxsackievirus B3(CVB3) so as to study the therapeutic effect of simvastatin on viral myocarditis.Methods Sixty male BALB/c mice were divided into five groups randomly(n=12).Mice in viral control group and three groups of oral administration of simvastatin(10,30 and 90 mg?kg-1)were inoculated intrapritoneally with 0.2 mL of CVB3(Nancy strain).Mice in normal control group were inoculated intrapritoneally with 0.2 mL Eagle's solution.The heart samples of all the mice were obtained for hispathological study and detection of myocardial LCCs alpha1 subunits mRNA expression by semi-quantitative reverse transcription-polymerase chain reaction(RT-PCR).Results In viral control group,the mononuclear inflamematory infiltrate was focal or diffuse in myocardium of mice,severe hearts revealed a large area of myocardial necrosis.The degree of inflammatory cell infiltrate and area of necrosis were significantly less in simvastatin groups as compared with viral control group.The myocardial LCCs alpha1 subunits mRNA expression by semi-quantitative RT-PCR in normal control group was much lower than that in viral control group(0.06?0.01 vs 1.37?0.32,P

Objective To investigate the diagnosis and the curative effects of interventional therapy by spiral CT in rupture of hepatocellular carcinoma(HCC). Methods 46 patients were checked by spiral CT and abdominal puncture of non-condensable blood. All the patients were treated by the transcatheter arterial embolization (TAE) with iodinated oil and/or gelatin sponge. Results Characteristic findings were detected in 31 patients,of which 7 patients were chiefly detected by spiral CT. The bleeding of ruptured HCCs was controlled effectively in all the cases treated by TAE without serious complications. Conclusion Spiral CT is susceptive to the diagnosis of the ruptured HCC. TAE can be the chiefly treatment in ruptured HCC with fewer serious complications.

Objective The objective of this study was to explore the difference factors for PHC patients by transcatheter arterial chemoembolization of different age groups of senior people in China and support reference for individualized intervention by clinical medical workers.Methods 153 cases of PHC patients by TACE were selected by convenience sampling method from October 2013 to June 2014.The data were collected using general data questionnaire,Health Promotion Strategy Scale,QOL-LC,Memorial Symptom Assessment Scales and Social Support Scale to evaluate the physical,psychological and social aspects of the PHC patients.We divided the patients into young,middle-aged and elderly groups.Single factor and multiple factors regression analysis were used to compare the status and influencing factors.Results Psychological function,value of blood AFP,marital status entered the model and were self-care efficacy and correlated factors of young-aged patients,which could explain 50.6％ of the total varience.Physical symptoms,exploitation degree of support and intervention treatment times entered the model and were self-care efficacy and correlated factors of middle-aged patients,which could explain 47.8％ of the total varience.Symptom distress,degree of cuhural and psychological function entered the model and were self-care efficacy and correlated factors of elderly-aged patients,which could explain 42.4％ of the total varience.Conclusions The self-care efficacy were low in all ages of PHC patients by TACE,it is associated with a variety of factors.Doctors and nurses should pay more attention to the self-care efficacy for PHC patients by transcatheter arterial chemoembolization with different age groups.Also we should evaluate and make well-targeted policies and personalized inter-ventions to promote self-management self-efficacy.

] AIM: Lysophosphatidic acid (LPA) is a bioactive phospholipid known to have growth factor-like activity on fibroblasts, and is involved in cardiovascular diseases. Besides direct effects, usually, LPA can work together with other bioactive factors to regulate cardiovascular homeostasis by induction of their expression and production, or increase in their activity. Among variety of bioactive factors, adrenomedullin (ADM) is a multifunctional peptide with an important cytoprotective effect against cardiovascular damage, but the interaction between ADM and LPA on adventitia remains unknown. METHODS: The experiment was performed on the bath of isolated rat aortic adventitia, ADM produced and secreted from adventitia stimulated by LPA was detected by using radioimmunoassay, proliferation in adventitia cells was evaluated by the level of [3H]-thymine incorporation, and prepro ADM gene expression was measured by semi-quantitative reverse transcriptase polymerase chain reaction. RESULTS: It was found that LPA stimulated aortic adventitia to secrete ADM and express its mRNA in a concentration-dependent manner. ADM inhibited LPA-induced proliferation in adventitial cells, and attenuated the activity of mitogen activated protein kinase (MAPK) stimulated by LPA. In contrast, the treatment with specific antagonists of ADM receptor potentiated the LPA-induced proliferation in adventitial cells. CONCLUSION: LPA stimulates adventitia to produce and secrete ADM, and in turn, ADM produced by adventitia regulates the vascular biological effects of LPA. [

[Objective]This study was designed to observe the effects of endotoxin(LPS)on the growth activity and gap junction(GJ)of NRK52E cells.[Methods]The NRK52E cells were divided into control group and LPS groups,and the NRK52E cells in LPS groups were treated with LPS 10 ng/mL,50 ng/mL,100 ng/mL,500 ng/mL,and 1 000 ng/mL for 24 h respectively.The NRK52E cells growth activity was measured through MTT method,and the function of gap junction of NRK52E cells was measured through the method of fluoroimmunoassay.The protein expression of connexin 43(Cx43)in control group,LPS 10 ng/mL group,and LPS 100 ng/mL group were also determined by Western blotting.[Results]①Compared with control group and LPS 10 ng/mL group,The NRK52E cells growth activity decreased significantly in LPS 50 ng/mL,100 ng/mL,500 ng/mL,and 1 000 ng/mL groups(P＜0.01).②Compared with control group,the function of GJ decreased significantly in LPS 100 ng/mL,500 ng/mL,and 1 000 ng/mL groups(P＜0.01).③There were negative correlations among the concentration of LPS and NRK52E cells growth activity and GJ function respectively(r=-0.941,-0.872,P＜0.01).④Compared with control group,the protein expression of Cx43 were decreased significantly in LPS 10 ng/mL and 100 ng/mL groups(P＜0.01).[Conclusions]LPS can inhibit the NRK52E cells growth activity in a dose-depend manner.GJ function is one of the mechanisms.
