Objective To investigate autonomic nervous system(ANS)function of hyperthyroidism and hyperthyroidism by analyzing the heart rate variability(HRV)of patients with the diseases.Methods 12-synchronous dynamic 24-hour monitoring and man-machine dialogue were performed in 49 patients with hyperthyroidism,25 patients with hypothyroidism and 40 controls after removing interference,and 24-hour electrocardiogram wag analyzed.Heart rate variability indicators observed included 24-hour time-domain indexes[standard deviation of all experimental time RR(SDNN),root of mean square standard deviation from adjacent RR interval(RMSSD)]and 24-hour frequency domain indicators[very low frequency power(VLF),low-frequency power(LF),high frequency power(HF),low frequency power/high frequency power(LF/HF)].Results Indicators of time domain in hyperthyroidism group,such as SDNN[(69.65±13.55)ms]and RMSSD[(12.98±3.20)ms]were obviously lower than those of the control group[(136.07±11.95),(29.70±5.85)ms],the differences being statistically significant (P＜0.01).Indicators of frequency domain HF[(5331±15.84)msz]were lower than those of the control group [(223.38±50.09)ms2],butVLF[(1823.55±238.13)ms2],LF[(501.88±92.47)ms2]and LF/HF(5.89±1.15)was higher compared with that in the control group,repectively[(325.68±60.47)ms2,(405.60±5 1.41)ms2,2.14±0.56,P＜0.01).Among time domain indicators in hypothyroidism group,SDNN[(77.00±15.48)ms]and RMSSD [(14.80±2.58)ms]were also obviously lower than those in the control group(P＜0.01),the difference being significant statistically(P＜0.01).Frequency domain index HF[(57.88±12.20)ms2],VLF[(251.48±24.67)ms2],LF[(128.68±43.78)ms2]also obviously lower than those in the control group(P＜0.01),but LF/HF,being 1.83±0.63,was in a normal range and did not significantly changed(P＞0.05). Conclusion In patients with hyperthyroidism both sympathetic and vagus nerves are hyperdynamic,while in patients with hypothyroidism,vagus nerves are hyperdynamic,while sympathetic nerve hypodynamic.

Objective To explore the changes of plasma somatostatin(SST) in children with septic shock.Methods The level of plasma SST in children with septic shock (test group,n=21) on an empty stomach at shock stage,blood pressure and heart rate recovery stage,recovery stage(at that time clinical symptoms and signs disappeared,infection indicators such as blood routine and CRP returned to normal,about 6-12 days after admission) were detected by competive radioimmunassay,the level of SST in healthy children(healthy control group,n=25) on an empty stomach on morning was detected,too.The levels of plasma SST between septic shock concbined with paralytic ileus group and without paralytic ileus group were compared.Results 1.Level of plasma SST of test group at shock stage[(44.60?16.83) ng/L]was significantly lower than that of control group[(123.15?6.57) ng/L](t=-12.16 P0.05).The level of plasma SST of children with paralytic ileus [(28.10?7.0) ng/L] was significantly lower than that of children without paralytic ileus [(56.98?9.44) ng/L](t=-7.70 P

Objective:To explore the role of 6-CYANO-2,3-DIHYDROXY-7-NITROQUIN OXALINE (CNQX) in different types of synapse secretion.Methods:The spontaneous mEPSCs and eEPSCs at different extracellular concentrations of CNQX in cultured cortical or hippocampal neurons were recorded respectively.Results:The half inhibitory concentration (IC50) of CNQX in evoked neurotransmitter release was significantly higher than that of spontaneous release,indicating that the spontaneous neurotransmitter release was more sensitive to CNQX.No apparent difference was observed between cortical and hippocampal cells,suggesting that the blocking effect of CNQX was similar in different brain regions.Conclusion:CNQX might have differential regulating mechanisms between excitatory spontaneous and evoked neurotransmitter release,but without brain regions specificity.

It described US medical schools' (U.S. Virginia University School of medicine, for example) implementation ap-proach of translational medicine ideas in different stages, such as before entering school, during the period of school, practice exam and physician clinician tralning. It provided the reference for the de-velopment of translational medicine education in the process of China clinician education and tralning, including:medical students' integration into the related clinical research in preschool through volunteer service, the choice of multiple combination model of clinical science and basic research, interdisci-plinary examination of medical practitioners and the provisions of the research work in resident and specialist tralning stage.

Objective To explore the preventive effect of early bowel intervention on the gastrointestinal dysfunction in patients with invasive mechanical ventilation.Methods Sixty patients with invasive mechanical ventilation were equally randomly divided into the observation group and the control group.patlents in the control group were treated by conventional nursing care,while Patients in the observation group were given the early bowel intervention including abdominal massage and stimulation of rectum.The two groups were compared in terms of gastrointestinal dysfunction.Result The rate of gastrointestinal dysfunction in the observation group was significantly lower than that of the control group(P<0.05).Conclusion The early bowel intervention may effectively promote intestinal peristalsis,protect the intestinal digestion, absorption of nutrients and mucosal barrier function and prevent gastrointestinal dysfunction in patients with invasive mechanical ventilation during enteral nutrition.

Objective To investigate the impact of alterations within the space of Disse micro- environment on the migration of hepatic stellate cells(HSC) during the process of liver fibrosis,and to ex plore the novel mechanism of liver fibrosis from the view of cell migration.Methods A modified in vitro Boyden chamber system to partially mimic in vivo microenvironment of Disse space of normal and liver fibrosis was employed.The effects of fibrogenetic growth factors on the migration of HSC in liver fibrosis were observed via cell migration and cell proliferation experiments.Results Enhanced platelet-derived growth factor(PDGF)-BB,transforming growth factor(TGF)-?1 and/or epithelial growth factor(EGF) in liver fibrosis resulted in an increase in migratory capacity of activated HSC.The enhanced migration of HSCs induced by PDGF-BB was partially associated with their increased proliferation,while,TGF-?1 or EGF-induced migration was proliferation independent.The elevation of basic fibroblast growth factor (bFGF) or vascular endothelial growth factor(VEGF)during liver fibrosis had no effect on the migration of HSCs.Conclusions The study provides valuable insights into the role of space of Disse microenvironment in regulating HSC migratory behavior.TGF-?1,PDGF-BB and EGF,which increased in liver fibrosis, could induce the migration of activated HSC.However,bFGF or VEGF has no such kind of effect,al- though they also increased during liver fibrosis.

Objective To investigate the distribution of characteristics,clinical manifestations,laboratory parameters and activity index of patients with systemic lupus erythematosus (SLE) and to determine their role in helping to make correct clinical diagnosis and disease the activity evaluation of SLE.Methods Collect the data of 1037 SLE patients of Ningxia Medical University Affiliated Hospital from January 2006 to June 2010.Data were analyzed with t test and Chi-square test.Results Over the past three years,there were more and more patients were admitted year by year.Among the 1037 cases of SLE patients,most of them 20-40 year-old woman,accounting for 67.5％ of the whole patient population,with a male to female ratio was 1:8.26.Joint pain was the most common initial symptom,accounting for 54.3％,followed by skin rash,accounting for 48.2％.Decreased complement C3 level and platelets counts, proteinuria,and positive anti-dsDNA antibody could be used as indicators for early diagnosis of SLE.SLEDAI activity score higher than 9 were presented in 26.0％ of patients.Factors that could impact the final score of SLEADI were fever,arthritis,skin rash,proteinuria,low complement levels,high titers of anti-dsDNA antibody,pleurisy,alopecia,mucosal ulcers,pericarditis,mental illness and decreased platelets count.Patients with active disease had a higher accidence of fever,arthritis,skin rash,lung damage,alopecia,mucosal ulcers,heart damage,mental illness and renal damaged,low complement levels,high level of anti-dsDNA antibody titers and elevated erythrocyte sedimentation rate.Conclusion SLE is a multi-system disease with multiple organ involvement,with characteristic clinical symptoms and immunological abnormalities,thus early diagnosis is very important.Understanding the characteristics of the diseases,correct judgement of the disease activity,reasonable and effective treatment all can delay the development of organ damage and improve the prognosis.

Abstract: Objective　In order to provide reference for emergency treatment of a sudden food poisoning incident, pathogen detection and drug resistance analysis were carried out. Methods　Diarrheal stool and surplus food samples were detected by GB 4789 and the isolates were identified by VITEK2 and matrix assisted laser desorption ionization-time of flight mass spectrometry (MALDI-TOF MS), at the same time, the bacterial drug sensitivity test was carried out by using the method of microbroth dilution, and the isolates from different sources were molecularly classified by pulsed field gel electrophoresis (PFGE), and the correlation between the strains was analyzed by BioNumerics software. Results　Totaly 13 leftovers and 3 diarrhea patients were isolated and identified, The total number of colonies and coliforms in 7 leftovers samples all exceeded the standard, and Citrobacter freundii was detected in 5 leftovers and 2 stools. The results of drug sensitivity test showed that seven strains of Citrobacter freundii were sensitive to ciprofloxacin, tetracycline, chloramphenicol, gentamicin, amikacin, cefotaxime and meropenem, but completely resistant to ampicillin, and there was no multiple drug resistance. The results of pulsed field gel electrophoresis (PFGE) showed that 7 strains of Citrobacter freundii had the same PFGE bands and 100% homology, showing the same clone. Conclusions　This food poisoning incident was caused by Citrobacter freundii. The pathogen of food poisoning can be quickly and accurately determined by MALDI-TOF MS, which is beneficial to the early diagnosis and treatment of infectious diseases. It is suggested to strengthen the corresponding management, improve food safety awareness and prevent similar incidents.

OBJECTIVEIt laid the foundation of the large sample data mining for a comprehensive summary concerning four properties theory of traditional Chinese medicine (TCM), and also provided theory clues on determination of four properties for the new resource development of TCM and the clinical use of Chinese medicine.

METHODFour properties data of 8 980 Chinese medicines from "Chinese herbal medicine (CHM)" and associated function index data were chose as data sets. Then, the IBM SPSS Clementine 14.1 data mining platform and Apriori model were adopted to mining classification-association rules, setting the minimum support threshold of rule antecedent and the minimum confidence threshold as 0.5% and 60%.

RESULT11 classification-association rules involved in warm, cold and mild natures were found.

CONCLUSIONIt was discovered that the TCM with functions of "dispelling wind-cold, warming the middle, stopping pain and expelling wind-removing dampness, tonifying kidney yang, unblocking meridians and expelling wind-removing dampness, dispelling cold to stop pain, strengthening sinews-bones and expelling wind-removing dampness" was likely warm-natured, with functions of "tonifying the lung" was likely mild-natured, and with functions of " clearing heat and drying dampness, clearing heat and purging fire, eliminating restlessness" was likely cold-natured.
