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 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 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.

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 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]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.

ObjectiveTo investigate the mechanism of anti-inflammatory effect of diallyl sulfide (DAS) in protection against acute lung injury (ALI) in rats with paraquat poisoning.Methods Eighty male Wistar rats were randomly divided into four groups, namely: control group, model group, dexamethasone (DXM) treatment group, and DAS treatment group, with 20 rats in each group. The model of paraquat poisoning was reproduced by single does of 70 mg/kg given by gavage, while the same volume of normal saline (NS) was given in same manner in control group. 100 mg/kg of DAS, the same volume of NS, or 1 mg/kg DXM injection were given respectively in DAS treatment group, model group, or DXM treatment group intraperitoneally after exposure to paraquat, once a day for 14 days. Five rats in each group were sacrificed at 1, 3, 7, 14 days, respectively. The inferior lobe of right lung was harvested, and the degree of lung injury was observed with hematoxylin and eosin (HE) staining under optical microscope; the upper lobe of right lung was used to determine the lung wet/dry weight (W/D) ratio and for evaluation of the degree of pulmonary edema. The expression of nuclear factor -κB (NF-κB) in the middle lobe of right lung was assessed with immunohistochemistry. The expression of tumor necrosis factor -α (TNF-α) mRNA in the left lung was determined with the reverse transcription-polymerase chain reaction (RT-PCR).Results① The pulmonary structure in control group was found to be intact. However, in the model group there were progressive pathological changes in lung, including marked edema and thickening of alveolar walls, collapse of alveoli, infiltration of inflammatory cells, alveolar wall, and obvious bleeding in the local lung tissue, and formation of transparent membrane in alveolar space. Less infiltration of inflammatory cells and no obvious destruction were found in alveolar structure in the DAS and DXM treatment groups.② Lung W/D ratio: lung W/D ratio of model group was apparently higher than that in control group at every time point, and peaking on the 3rd day (6.15±0.54 vs. 4.15±2.10,P< 0.05), and the ratio of lung W/D of DAS and DXM treatment groups was obviously lower than that in model group at every time point, especially on the 3rd day (3.99±1.26, 4.30±0.70 vs. 6.15±0.54, bothP< 0.05), but there was no significant difference between DAS and DXM treatment groups in this regard.③ The immunocytochemistry analysis revealed minimal NF-κBp65 expression in the cell nuclei of the control group, while extensive NF-κBp65 expression was found in model group. Minimal NF-κBp65 positive expression in the cytoplasm and even less positive expression in the nucleus was found in the DAS and DXM treatment groups, and integralA value was significantly lower in the DAS and DXM treatment groups than that of the model group, especially on the 3rd day [(17.98±0.06)×107, (18.53±0.04)×107 vs. (28.85±0.61)×107, bothP< 0.01], but there was no significant difference between DAS and DXM treatment groups.④ It was shown by RT-PCR that the expression of TNF-α mRNA in lung tissue of the model group was significantly higher than that in the control group on the 3rd day (gray value: 3.63±0.62 vs. 0.51±0.13, P< 0.05). The expression of TNF-α mRNA in lung tissue was significantly decreased in DAS and DXM treatment groups compared with model group (gray value: 2.49±0.57, 2.02±0.26 vs. 3.63±0.62, bothP< 0.05), but there was no significant difference between DAS and DXM treated groups.ConclusionTreatment with an intraperitoneally injection of DAS is capable of attenuate the extent of PQ-induced ALI in rats by alleviating pulmonary edema, inhibiting the expression of NF-κB and TNF-α in lung tissue, and ameliorating pathological changes in lung tissue.
