Objective To compare the prognosis effect of different Helicobacter pylori (Hp)eradication methods in patients with chronic gastritis.Methods One hundred and twenty patients with chronic gastritis diagnosed by gastroscopy and pathology examination were divided into sequential therapy group (36 cases),triple-combined therapy group (34 cases),Hp positive without eradication group (30cases) and Hp negative group (20 cases) according to the Hp infection status.All patients were followed up by gastroscopy,biopsy and rapid urease test before and after therapy.Results The Hp eradication rate in sequential therapy group was 94.44％ (34/36),in triple-combined therapy group was 73.53％ (25/34),and there was statistical difference (x2 =5.775,P =0.016).The symptoms scores and gastroscopy scores after therapy in the four groups were significantly lower than those before therapy,and there were statistical differences (P ＜ 0.05).The symptoms scores and gastroscopy scores after therapy in sequential therapy group were significantly lower than those in triple-combined therapy group,and there were statistical differences (P ＜0.05).The symptoms scores and gastroscopy scores after therapy in sequential therapy group,triple-combined therapy group and Hp negative group were significantly lower than those in Hp positive without eradication group [(0.84 ± 0.60),(1.34 ± 0.59),(1.49 ± 0.62) scores vs.(2.98 ± 0.54) scores,(0.47 ± 0.37),(0.83 ± 0.35),(0.96 ± 0.75) scores vs.(1.22 ± 0.40) scores],and there were statistical differences (P ＜ 0.05).Conclusions The Hp eradication rate of sequential therapy is higher than that of triple-combined therapy.The two therapy methods can both improve the symptoms score and gastroscopy score,but the symptoms after sequential therapy are relieved faster compared with triple-combined therapy.

Performance management is a key strategy tool for a hospital to achieve its planned goals,and performance negotiation plays a key role in performance management which consists of performance planning,execution,evaluation and feedback.The negotiations emphasize differently in the negotiations,as short of which effective performance management is out of the question.To cultivate an incentive-oriented negotiation culture and build a negotiation system make a great difference in solving problems of performance management and promoting efficacy of hospital performance management.

Objective To evaluate the role of delta and kappa opioid receptors in sufentanil preconditioning (SPC)-induced attenuation of myocardial ischemia-reperfusion (I/R) injury in rats.Methods Forty adult male Sprague-Dawley rats,aged 2-3 months,weighing 250-330 g,were randomly divided into 5 groups (n =8 each) using a random number table:sham operation group (group S),group I/R,group SPC,δ receptor antagonist naltrindole + SPC group (NTD + SPC group),and κ receptor antagonist nor-binaltorphimine (nor-BNI) + SPC group (BNI + SPC group).Myocardial I/R was induced by 30 min occlusion of left anterior descending branch of coronary artery followed by 120 min reperfusion.In group SPC,5 min infusion of sufentanil 3μg/kg was repeated 3 times at 5 min interval before myocardial ischemia.In NTD + SPC group,naltrindole 5 mg/kg was intravenously injected,at 10 before SPC.In BNI + SPC group,nor-BNI 5 mg/kg was injected intravenously at 15 min before SPC.Arterial blood samples were collected at 120 min of reperfusion for measurement of the serum cardiac troponin I (cTnI) and creatine kinase isoenzyme-MB (CK-MB) concentrations.The rats were then sacrificed and hearts removed for determination of myocardial infarct size (IS) and area at risk (AAR).IS/AAR ratio was calculated.Results Compared with S group,the serum cTnI and CK-MB concentrations were significantly increased in I/R,NTD + SPC and BNI + SPC groups,and the serum CK-MB concentrations were increased in SPC group,and IS/AAR ratio was increased in I/R group (P ＜ 0.05 or 0.01).The serum cTnI and CK-MB concentrations were significantly lower in SPC,NTD + SPC and BNI + SPC groups and IS/AAR ratio was lower in SPC and BNI + SPC groups than in I/R group,and higher in NTD + SPC and BNI + SPC groups than in SPC group (P ＜ 0.05 or 0.01).Conclusion Both κ and δ opioid receptors mediate SPC-induced attenuation of myocardial I/R injury in rats.

Rare sugars were defined as monosaccharides and their derivatives that rarely exist in nature. They played an important role in food, health, medicine and etc A strategy for bioproduction of rare sugars, namely Izumoring, was described. By the Izumoring method, all monosaccharides and polyols could be linked, using enzymatic reaction with D-tagatose 3-epimerase, aldose isomerases and polyol dehydrogenases. Izumoring for hexoses, pentoses and tetroses were designed respectively. According to this strategy, the bioproduction routes of various rare sugars, using microbial and enzymatic reactions, could be obtained. In addition, the future research tendency of biotransformation of rare sugars was put forward.

Objective To investigate the impact and significance of the vagus nerve intervention on the atrial electrical emodeling.Methods 30 mongrel dogs were given metoprolol in order to eliminate the effects of sympathetic nerve on atrial electrical remodeling;observe the atrial effective refractory period (ERP) and atrial fibrillation susceptible window(VW) in the high right atrial(SA) and coronary sinus (CS) by the vagus nerve stimulation(VS) or vagus nerve stimulation(Non-VS) before and after using atropine and after atrial electrical remodeling was observed.Results Before using vagus nerve blocking agents atropine,ERP shortened significantly [(54.83 ± 46.23) ms] and VW increased significantly [(19.86±13.23) ms] after VS,this time with atrial fibrillation-prone ; After using atropine,ERP increased significantly [(112.33 ± 9.63) ms] under VS,did not induce atrial fibrillation; After atrial electrical remodeling,the value of ERP was no significant difference under basis and VS (t =2.116,0.853,all P ＞0.05).Conclusion VS can increase the atrial electrical remodeling,an increase of atrial fibrillation susceptibility;vagus nerve block can reduce atrial electrical remodeling and atrial fibrillation susceptibility decreased.

A yeast strain KM12 , which can convert conjugated anthraquinone of rhub arb to free anthraquinone , was screened. And it is identified as Kluyveromyces marxianus by 26S rDNA. The percentage of free an-thraquinone in total anthraquinone of rhub arb as an indicator was used to investigate the effect of culture medium component and fermentation processing conditions, such as seed age, fermentation time and liquid volume on con-version of conjugated anthraquinone by KM12. The optimal fermentation medium was determined by orthogonal test L9(43) and the composition (%) is yeast extract 1, glucose 2, and rhubarb 2. The 5% (V/V) of the seed culture inoculated 36-48 h was inoculumed to fermentation medium in shake flask to ferment at 30℃, 200 r?min-1 for 4 days. TLC analysis showed most of conjugated anthraquinone decomposed or converted into free anthraquinone in fermented rhub arb . It was concluded that the side effect of severe diarrhea caused by Chinese medicine rhub arb can be alleviated through fermentation processing by KM12 strain .

Objective To determine the contributions of main chemical compositions of extracts of Eucalyptus camaldulensis represented by GC/MS elute peaks to the molluscicidal activities,and explore a shortcut of looking for the effective components from natural products. Methods E. camaldulensis leaves were collected consecutively in 12 months at the same place,extracted with dichloromethane,analyzed by GC/MS,and their LC50(s)of molluscicidal activities were tested according to the method rec-ommended by WHO. The correlation of the main components in 12 extracts and their molluscicidal activities were analyzed by the grey relative correlation analysis model with software GTMS 3.0. Result All the dichloromethane extracts of eucalyptus leaves showed excellent molluscicidal activities with the highest LC50 of 0.257mg/L and 0.242mg/L for the samples in June and July and the lowest LC50 of 6.802 mg/L and 5.406 mg/L in December and January respectively. The structures of 16 main chemical compo-nents were elucidated by GC/MS and NIST Mass Spectral Library,most of which were monoterpenes and sesquiterpenoids. The gray correlation coefficients with activity were all over 0.5,the first five over 0.9 were 4,4,8-Trimethyltricyclo[6.3.1.0(1,5)]do-decane-2,9-diol,(-)-Spathulenol,a structural isomer of(-)-Spathulenol,Eucalyptol and Ledol. Conclusion The most main in-gredients in the dichloromethane extracts of E. camaldulensis leaves show good correlations with the molluscicidal activity,which suggests that the molluscicidal role is synergistically played by the multiple components together.

Objective To compare the effect of active compression-decompression cardiopulmonary resuscitation(ACD-CPR) with standard- cardiopulmonary resuscitation(S-CPR) on ventricular function in a canine ventricular fibrillation model. Methods Ventricular fibrillation was induced in anesthetized and instrumented canine. Twenty-four dogs were randomly assigned to either ACD-CPR group or S-CPR group.After 4 minutes of untreated VF,two-dimension echocardiography was used to evaluate the left ventricular end-diastolic volume(LVEDV),left ventricular end-systolic volume(LVESV) and left ventricular ejection fraction (LVEF) of every canine of the two groups when they were undergoing cardiopulmonary resuscitation. Results During ventricular fibrillation, both ACD-CPR group and S-CPR group showed decreased LVEDV compared with pre-ventricular fibrillation, but not statistically significant( P ＞0.05).LVEDV was increased in ACD-CPR group compared with S-CPR group, but not statistically significant (P＞ 0. 05). Both ACD-CPR group and S-CPR group showed significantly increased LVESV compared with pre-ventricular fibrillation,of which the difference was statistically significant ( P ＜0. 001). Both ACD-CPRgroup and S-CPR group showed significantly decreased LVEF compared with pre-ventricular fibrillation,of which the difference was statistically significant (P ＜0. 001). LVEF was increased in ACD-CPR group compared with S-CPR group,of which the difference was statistically significant ( P = 0.019). Conclusions Compared with S-CPR,ACD-CPR resulted in higher LVEF.
