AIM To study if cholecystokinin octapeptide (CCK-8) alter cardiovascular functions by its direct inhibitory effect on carotid sinus baroreceptor (CSB) activity. METHODS The functional curve of carotid baroreceptor (FCCB) was constructed and the functional parameters of carotid baroreceptor were measured by recording sinus nerve afferent discharge in anesthetized male rats with perfused isolated carotid sinus. RESULTS ① CCK-8 0.1, 0.5 and 1.0 μmol·L-1 shifted FCCB to the right and downward, with a marked decrease in peak slope and peak integral value of carotid sinus nerve discharge in a concentration-dependent manner, indicating the inhibitory effect of CCK-8 on CSB activity. ② Pretreatment with proglumide (100 μmol·L-1), a nonselective CCK receptor antagonist, or Bay K8644 (0.5 μmol·L-1), an agonist of calcium channel, partially attenuated the inhibitory effect of CCK-8 (0.5 μmol·L-1) on CSB activity. Pretreatment with L-NAME (100 μmol·L-1), an inhibitor of NO synthase, did not affect the inhibitory action of CCK-8. CONCLUSION CCK-8 inhibits CSB activity, which may be mediated by activating CCK receptors in the carotid sinus area and thereby resulting in an inhibition of stretch-sensitive channels and decrease in Ca2+ influx.

Objective To preparegraphene quantum dots (GQDs) and construct a novel biosensor for determination of dopamine (DA) and uric acid (UA).Methods The GQDs was prepared by carbonization method from citric acid as carbon sources.Differential pulse voltammetry was used by the modified electrodes to detect uric acid and dopamine,and the detection performance was evaluate.Collected three experimenters morning urine on July 29,2016.The proposed sensor was used for biological samples detection.Results The size of GQDs were between 3 to 5 nm,which was observed by transmission electron microscopy (TEM).The proposed sensor had good linear correlation of 50～600 μmol/L UA (r2 =0.996 6) and 2～ 240 μmol/L DA (r2 =0.992 5).In uric acid in urine samples' detection (n=3),RSD value was less than 3％.The standard addition recovery rates of UA and DA were in 95.7％～101.4％ and 96％～102％ respectively.Conclusion The biosensor based on GQDs for determination DA and UA had been constructed successfully.

Objective To survey on the condition of critically ill children in emergency room (ER) for improving the care for them.Methods Data of 374 critically ill children in emergency intensive care unit (EICU) were recorded in the respects of mode of sending them to ER,rescue during transport,length of stay in ER,blood gas,electrolytes,accuracy of assessing pediatric critical illness score/neonate critical illness score (PCIS/NCIS) and Glasgow Coma Scale (GCS),correctness of determining SIRS,sepsis and septic shock.Results Of 374 patients,neonates were 29.9％,and the mean age of children patients not including neonate was 37.4 months.The mean length of ER stay was 4.7 hours (0.42-96 hours).Of 374 patients,those with infection diseases were 47.6％,and the main vehicles for transportation of patient sent to ER were Taxi (38.3％),ambulance (28.4％) and private cars (21.5％).Total fatality was 12.3％ and ER fatality ( 15.6％ ) was higher than in - hospital fatality ( 10.3％,P ＜0.01 ).The mean PCIS/NCIS of 374 patients were 81.92 ± 9.66,and the PCIS/NCIS ≤ 90 accounted for 81％.Of assessed GCSs of 172 patients,GCS≤8,GCS 9-12 and GCS 13-15 accounted for 35.5％,21.5％ and 43.0％ respectively,and fatalities were 26.23％,10.81％ and 5.41％ correspondingly (P ＜0.01 ).The PCIS values of GCS≤8 and GCS 9-12 patients were lower than those of GCS 13-15 patients (P ＜ 0.01 ).There was no significant difference in PCIS between GCS≤8 and GCS 9-12 ( P ＞ 0.05 ).PCIS and GCS were positively correlated (r=0.454,P=0.01).Of374 patients,41.7％ had SIRS,and 25.7％ had sepsis.Of 262 children not including neonates,43.5％ had shock,and 61.4％ of these shock children were septic shock.In 374 patients,those with hyponatremia accounted for 37.2％,and those with hyperkaliemia accounted for 22.0％.The rate of hypoglycemia found in neonates was 20.91％ and rate of hyperglycemia occurred in neonates was 29.1％.The rate of hypoglycemia found in children patients was 9％ and hyperglycemia was 66.7％.Patients with pH ＜ 7.35 accounted for 67.8％ and those with pH ＜ 7.2 were 33.1％.Conclusions The majority of children patients in pediatric ER were neonates and infants.The length of ER stay was short with mean value of 4.7 hours (0.42-96 hours).ER fatality was higher than in - hospital fatality,suggesting the critically ill children patients should be admitted as early as possible.The rate of using ambulance was only 28.4％.The Emergency Medical Service (EMS) should be improved to enhance the public sense of the EMS available.PCIS/NCIS can be used in ER for assessing the conditions and prognosis of critically ill children.GCS ≤8 and GCS 8-12 patients accounted for 57％ with majority of nontrauma brain injury.The values of PCIS in GCS≤8 and GCS 9-12 patients were much lower than those in GCS 13-15 patients.Patients with GCS ＜ 13 might be in critical settings.Majority of shock patients were septic shock (61.4％).Hyponatremia,hyperkalemia,hyperglycemia and hypoglycemia often occurred in critically ill pediatric patients and hypoglycemia not excepted in the neonates should have attention paid to.The main factor of acid -base balance disorder in critically ill children was acidosis (67.8％).

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.

Purpose To investigate the application value of diffusion weighted imaging (DWI) in differential diagnosis of common liver lipid-containing tumors.Materials and Methods Sixty patients with pathologically confirmed liver lipid-containing tumors from January 2011 to August 2015 were retrospectively analyzed,including 25 cases ofhepatocellular carcinoma (HCC),20 cases of hepatic adenoma (HA) and 15 cases of hepatic angiomyolipoma (HAML).Apparent diffusion coefficient (ADC) value and ratio of ADCtumor/ADCliver (rADC) of tumors were respectively measured.Routine MRI findings were analyzed.Results The MRI findings of these three common liver lipid-containing tumors were with their own characteristics.For HCC,HA and HAML,the average ADC value was (1.225±0.221)×10-3 mm2/s,(1.318±0.212)×10-3 mm2/s and (1.317±0.297)×103 mm2/s,respectively,(b=800 s/mm2);the average rADC value was 1.004± 0.151,0.984 ± 0.146 and 1.027±0.223,respectively.There was no significant difference in ADC and rADC among these three tumors (P＞0.05).Conclusion ADC and rADC had no differential diagnosis value in common liver lipid-containing tumors.Routine MRI signals and enhanced imaging features are the main diagnostic basis.

AIM: To explore the molecular mechanism in the pathogenesis of dilated cardiomyopathy (DCM) by analyzing the expression of T cell signaling molecules in mice with autoimmune DCM. METHODS: Mouse DCM model was induced by immunizing the animals with adenine nucleotide translocase (ANT) synthetic peptides. P56lck in T cells was detected with real-time fluorescent quantitative PCR in both DCM-group and the sham-immunized controls. At the same time, flow cytometry was used for quantity of Th cell intracellular cytokine IFN-? and IL-4, ELISA for examining the level of serum anti-ANT antibody, immune histochemistry for investigating the expression of CD45 in Th cells. RESULTS: The mRNA expression of P56lck ( 1 369.51 ?874.05 vs 47.93?10.21, P

AIM:To clarify the mechanism of treating autoimmune cardiomyopathy at different stages with anti-L3T4 monoclonal antibody.METHODS:Mice immunized with human mitochondria ADP/ATP peptides were used as the cardiomyopathy(DCM) group,and the sham-immunized mice were regarded as the controls.Mice receiving early treatment were immunized with the same peptides,followed by the injection of 400 ?g of anti-L3T4 on day 0,1 and 2 post-immunization.Mice in the late treatment group were immunized as of the early treatment group but anti-L3T4 was administered 3 months post-immunization.The cytokine expression was measured with three-color flow cytometry to quantitate the splenic Th1/Th2 cell subsets in the different groups of mice.In addition,serum and myocardial cytokines were measured by enzyme-linked immunosorbent assay and real-time PCR.RESULTS:Th1 and Th2 subsets in the early treatment group were similar to those in control group,but were drastically lower than those in DCM group.Mice in the late treatment group showed an increased level of Th1-related cytokines,while the Th2 level was between the DCM and early treatment group.IFN-? and IL-6 levels in early treatment group were similar to those in control group.In the early treatment group,IL-4 level was higher than that in control and lower than that in DCM group,whereas IL-2 and TNF-? contents were lower than those in control and DCM group.In the late treatment group,IFN-? and IL-2 levels were higher than those in DCM group and lower than those in the early treatment group,while IL-6 and IL-4 levels were lower than those in DCM group.CONCLUSION:These results suggest that the cytokine production in cardiomyopathic mice may be repressed by treatment with anti-L3T4 at different stages.Early treatment with anti-L3T4 has better inhibitory function than treatment in late stage of autoimmune cardiomyopathy.

The cytokine repertoire of ADP/ATP carrier-specific humoral immune responses and the cytokine-dependent anti-ADP/ATP carrier antibody IgG subclasses were examined in a cohort of ADP/ATP carrier-immunized BALB/c mice treated with anti-CD4 monoclonal antibody. Eighteen male BALB/c mice (6-8 weeks old) were randomized into 3 groups: dilated cardiomyopathy (DCM) group, DCM-tolerance (Tol) group and control group. The mice in DCM group were immunized with the peptides derived from human ADP/ATP carrier protein for 6 months and mice in the control group were sham-immunized, while the mice in DCM-Tol group were immunized with ADP/ATP carrier protein and anti-CD4 McAb simultaneously. Serum autoantibody against ADP/ATP carrier and IgG subclasses were measured by ELISA, intracellular cytokines IFN-gamma and IL-4 of Th cells were monitored with flow cytometry, and splenic T cell cytokines IFN-gamma, IL-2, IL-4 and IL-6 were detected by using real-time fluorescent quantitative PCR. The results showed that the autoantibody against ADP/ATP carrier was found in all mice in DCM group, and the antibody level, serum IgG1 and IgG2a subclasses, cytokines in T cells and Th cells were all elevated in DCM group, as compared with those in control group (P<0.01). On the other hand, in DCM-Tol group, the autoantibody level and contents of all the cytokines were significantly different from those in DCM group (P<0.01), and were close to those in control group. And the levels of IgG1, IgG2a, IgG2b and IgG3 were influenced, to varying degrees, by anti-CD4 McAb as compared with those in DCM group. All these four types of IgG subclasses were substantially decreased in DCM-Tol group as compared with DCM group. It is concluded that the treatment with anti-CD4 McAb could prevent the activation of T cells, reverse the abnormal secretion of cytokines and the imbalance between Th1/Th2 cell subsets and abnormal production of autoantibody against ADP/ATP carrier, and eventually avoid myocardial injuries.
