Objective To investigate the relationship between colonic dynamic abnormality and psychological factors in elderly patients(EP) with chronic idiopathic constipation(CIC). Methods 59 elderly patients with CIC and 36 elderly healthy subjects(EHS) were analysed. Total and segmental colonic transit times were assessed radiographically using radiopaque markers method. All subjects completed a self-rated inventory assessing psychological distress including depression(SDS) and anxiety(SAS). Results (1)Total and segmengal colonic transit times were significantly prolonged in elderly patients with CIC than in EHS (P

AIM: To study the phosphatidylinositol metabolism of vascular endothelial cells exposed to projectile's pressure wave METHODS: The cultured endothelial cells were exposed to bullet's pressure wave as experimental model. The intracellular inositol-1,4,5-triphosphate(IP_3), intracellular free calcium ([Ca 2+ ]i), protein kinase C(PKC) and lactate dehydrogenase (LDH) activities in cultural medium were assayed after the cultured cells exposed to bullet's pressure wave. After blocking phosphatidylinositol metabolism with neomycin, the above biochemical parameters of cells exposed to bullet's pressure wave were also measured. RESULTS: Bullet's pressure wave induced increase in the intracellular IP_3, [Ca 2+ ]i, and PKC activity obviously. The change of LDH activity paralleled with above biochemical changes. Blocking phosphatidylinositol metabolism partially inhibited these changes. CONCLUSION: Bullet's pressure wave may activate phosphatidylinositol metabolism, which may trigger the injury to the endothelial cells and lead to leakage of plasmatic LDH.

Objective To evaluate the efficiency and safety of amiodarone in patients with acute myocardial infarction (AMI) complicated ventricular tachyarrhythmia (CVT). Methods 106 CVT patients of AMI with stable haemodynamics was randomized into trial group (53 cases) and control group (3 cases). Based on routine therapy, the trial group was intravenously given amiodarone. Electrical cardioversion is necessary if the haemodynamics turns to unstable. Intravenous amiodarone will be used for at least 24 hours to maintain sinus rhythm. The control group was administrated intravenous lidocainein. If the patients made no response to lidocainein, given amiodarone as substitute. Electrical cardioversion is necessary when the haemodynamics turns to unstable and lidocainein was followed for at least 24 hours after successful cardioversion to maintain sinus rhythm. The therapeutic effects, cardiac function and the changes of arrhythmia were compared between the two groups. Results The incidence of angina pectoris, consumption of nitrates were decreased in trial group when compared with that in control group, whereas the ejection fraction, left ventricle fast filling interval and the mitral valve peak velocity of blood flow during left atrium contraction(E/A) all were higher than that in control group (all P<0.01). The total effective rate in trial group was higher than that in control group (75.5% vs 62.3%, P<0.01), especially the ventricular tachycardia control rate is significantly higher than control group (86.7% vs 50.0%,P<0.01). Conclusion Intravenous injection of amiodarone efficaciously control the complicated ventricular tachy-arrhythmia in patients with acute myocardial infarction as well as to improve the cardiac function.

BACKGROUND:Mesenchymal stem cels isolated from cord blood and bone marrow have multi-directional differentiation ability under a certain condition of induction. OBJECTIVE:To compare the difference of differentiation of umbilical cord blood and bone marrow mesenchymal stem cels into osteoblasts. METHODS:Human umbilical cord blood and bone marrow mesenchymal stem cels were isolated and cultured by density gradient method. When reached 90% confluency, mesenchymal stem cels were digested by trypsin for subculture. At the third passage, umbilical cord blood mesenchymal stem cels and bone marrow mesenchymal stem cels at 8×104/wel were incubated. When reached 80% confluency, cels were treated with low-glucose DMEM supplemented with 10% fetal bovine serum, 0.1 μmol/L dexamethasone, 50 μmol/L vitamin C and 10 mmol/L β-sodium glycerophosphate. RESULTS AND CONCLUSION:There was no significant difference in morphology and biological properties of the two kinds of mesenchymal stem cels. Cels were highly expressed CD44, CD29, but did not express CD34. They had the ability to differentiate into osteoblasts, which had a positive staining for known markers: alkaline phospatase and calciumin vitro mineralization. There was no significant difference in the activity of osteoblasts of two kinds of cels. Results verify that umbilical cord blood and adult bone marrow mesenchymal stem cels can be induced into osteoblasts with a similar ability, and they can be used as seed cels for bone tissue engineering.

OBJECTIVE In order to improve the traditional management mode,we try to explore the application of information technology for management of antimicrobial drugs during perioperative period. METHODS Through analysis of our research program case,the differences between the traditional management mode and the information-based management mode were compared by the method of reviewing literature data and analyzing hierarchy process of administration. RESULTS There were obvious limitations in the traditional management mode,but the information-based management mode exhibitsed evident advantages,because it focused on node control and process management. CONCLUSIONS The information-based management mode can establish a long-term management mechanism of antimicrobial drugs during perioperative period,and also can individualizedly implement precise management goal.It is an innovation of the traditional management mode.

Thirty-two male Sprague-Dawley rats were divided into control group (n =16) and fructose group (n =16) fed with 10％ fructose solution.After 4 weeks,the rats of two groups were treated with saline and 50 nmol/kg ghrelin for 6 weeks,respectively (each group n =8).Fasting plasma glucose,insulin,and blood lipid profile were measured.Insulin receptor (Ins-R) mRNA expression in muscle was detected by RT-PCR.The phosphorylation of insulin receptor substrate-1 (IRS-1) was measured by Western blot.The results showed that insulin level and homeostasis model assessment for insulin resistance index (HOMA-IR) in fructose group were higher than those in control group [(13.1±3.6 vs 9.0 ± 1.5) μU/ml,P＜0.05 ;2.78 ± 0.14 vs 1.81± 0.13,P ＜0.01)].After ghrelin treatment,plasma insulin concentration [(9.6 ± 2.5) μU/mL,P＜0.05] and HOMA-IR (1.96 ± 0.12,P＜0.01)significantly decreased,along with increased Ins-R mRNA and IRS-1 phosphorylation in skeletal muscle (P ＜0.01).These results suggest that ghrelin can ameliorate insulin resistance in fructose-fed rats by restoring Ins-R function.

Objective To study the iodine deficiency disorders (IDD) situation in Wenzhou City during 1995-2014.Method According to National IDD Surveillance Project,IDD surveillance had been consecutively carried out during the past 20 years,which consisted of goiter rate in 8-10 years old children,iodized salt and urinary iodine levels.Results The goiter rate of 8-10 years old children was decreased from the highest of 31.09％ (2 190/7 043) in 1995 to the lowest of 2.28％ (77/3 378) in 2014;the highest level of median urinary iodine was 214.78 μg/L,and the lowest level was 74.48 μg/L,and which was increased from 74.48 μg/L in 1995 to 187.00 μg/L in 1996,and then had been maintained at the appropriate level recommended by World Health Organiation (WHO),except that in 1998,2003,2004 and 2006.The qualified rate of iodized salt was increased from 54.95％ (1 471/2 677) in 1996 to 95.52％ (2 548/2 754) in 1999,but decreased to 62.75％ (768/1 224) in 2003,however it was fluctuated from 78.61％ (2 503/3 184) to 92.48％ (2 989/3 232) from 2004 to 2013,and it was 90.43％ in 2014 (2 983/3 300).Conclusions The comprehensive measures for controlling IDD,with universal salt iodization,has been gradually achieved remarkable effect in Wenzhou City,but the non-iodization salt existing in the market is still a problem,and people have misunderstandings about iodization salt.Iodine supplementation had better be conducted according to local conditions and based on scientific policy.

OBJECTIVE To set up an intranasal ovalbumin-induced animal model of allergic rhinitis(AR) accompanied with olfactory dysfunction in mice. By observing the olfactory pathway in mice using manganese-enhanced magnetic resonance imaging (MEMRI) and the relatively morphologic structural and immunological changes in olfactory epithelium, the influence of AR on olfactory receptor neurons(ORNs) was studied.METHODS Forty SD mice were randomly divided into two groups, the research group(n=30) and the control group(n=10). The research group was intraperitoneally injected and intranasal application of ovalbumin to establish an AR mice model. The olfactory function of the mice was evaluated by buried food test(BFT). ELISA was performed to measure the level of IgE in serum. MEMRI images were acquired with a 7.0 T micro-MR scanner. HE staining and immunohistochemistry were used to observe the tissues morphology change of olfactory mucosa and OMP expression.RESULTS The olfactory function evaluation of the AR mice model indicated that the incidence of olfactory dysfunction in AR mice was 40.0%. The AR mice with olfactory dysfunction had no signal enhancement in MEMRI. The olfactory epithelium became thinner, layer numbers of ORNs were decreased with disorder arrangement and the OMP expression was decreased in AR mice with olfactory dysfunction compared with that in AR mice without olfactory dysfunction(P=0.018) and the control group(P=0.0141).CONCLUSION An animal model of AR accompanied with olfactory dysfunction in mice was successfully established. The influence of AR on ORNs and thus cause the change of the olfactory pathway is one of the major pathogenesis of olfactory dysfunction in AR.

OBJECTIVE To retrospectively analyze the results of the composition and drug resistance of urinary pathogens isolated from geriatric inpatients from 2003 to 2005.METHODS The identification and antibacterial drug sensitivity test of urinary pathogens was carried out by VITEK AMS-60.RESULTS Urinary tract infections of geriatric inpatients were still mostly caused by Gram-negative bacilli(72.9%),others as Gram-positive cocci(14.3%) and fungi(12.8%).The majority of Gram-negative bacilli was Escherichia coli(46.6%) and the majority of fungi was Candida albicans(7.9%),as for Grampositive cocci,were Enterococcus faecalis(5.3%) and coagulase negative Staphylococcus(4.9%).Drug resistance rate of common antibiotic against the majority of urinary pathogens showed an ascending trend.CONCLUSIONS E.coli is still the primary urinary pathogen among geriatric inpatients,but the isolation of fungi and multi-drug-resistant bacteria is on the rise.
