In order to arouse the working enthusiasm of the entire staff and give expression to the value of labor and skills, our hospital has implemented reform in the distribution system. Bonus given to clinical departments is linked both to the amount and quality of work and to economic profits; bonus to medico technical departments is given by means of deducting a percentage from the income and expenditure surplus in a way of progressive decrease; bonus given to functional departments is equivalent to 90% of the average bonus given to medical service departments; and bonus to logistical service departments is given, if possible, by the piece and mark. As a result of the reform, the distribution system has become more rational, the working enthusiasm and efficiency of the staff have been enhanced, operational income and income structure have improved, and social benefits bave been raised, with the satisfaction rate reaching over 90%. Of course, there still exist some difficulties in the reform.

Objective To explore the effect and mechanism of intrathecal injecting κ-opioid receptor agonist U50, 488H on the rats with myocardial ischemia/reperfusion injury.Methods 50 Sprague–Dawley rats were randomly divided into five groups (n=10): sham group (Sham), ischemia/reperfusion group (IR), high-dose intravenous injection group (IV1), low-dose intravenous injection group (IV2), and intrathecal injection group (IT).In sham group the rats were followed by the modeling step without ligation of the left coronary and no drug injection by intravenous or intrathecal; in IR group the rats were underwent 30 minutes of myocardial ischemia followed by 120 minutes of reperfusion, and were not treated with any drug.All the rats in IV1, IV2 and IT groups were intravenous injected with U50, 488H at 1 hour before they were underwent myocardial ischemia/reperfusion as in IR group.IV1 and IV2 groups were intravenous injected with U50, 488H respectively at the dose of 0.1 mg/kg and 0.01 mg/kg, while the IT group was intrathecal injected with U50, 488H at the dose of 0.01mg/kg.All the rats from 5 groups were observed with cardiac ultrasound, myocardial sirius staining, serum CGRP and ET level.Results Compared to IR group(EF%=35.4 ±1.1,FS% =21.1 ±1.1), the rats in IT group (EF%=49.1 ±1.2,FS%=27.1 ±1.0) and IV1 group (EF%=46.3 ±2.2,FS%=26.6 ±0.6) showed better myocardial contraction (P<0.05) and reduced myocardial fibrosis (P<0.05).IT group and IV1 group also showed reduced ET but increased CGRP in the serum (P<0.05).There were no difference between IV2 group and IR group in both observation.Conclusion Pretreatment with intrathecal injection of opium κ-receptor stimulant U50, 488H not only protected the myocardial function from myocardial ischemia/reperfusion injury, but also repressed myocardial fibrosis.The protection may result from modulation of CGRP and ET.

OBJECTIVE To design the detection system of the leaky surface acoustic wave(LSAW) biosensor in(liquid) phase and detect human papilloma virus(HPV) target sequence with the LSAW biosensor.METHODS A detection delay line and a reference delay line were constructed,the phase of the two delay line changes was(evaluated) in liquid phase,and real time monitoring of HPV reaction was performed by using the LSAW biosensor system.RESULTS The phase of the two delay lines had different changes in liquid phase;HPV could lead to a great change of the phase in the detection delay line,and reference delay line had no change.CONCLUSIONS The(detection) system of the LSAW biosensor in liquid phase is successfully constructed and real time monitoring of(detection) of HPV is realized.

AIM: To investigate the role of nitric oxide synthase (NOS), soluble guanylyl cyclase (sGC) and protein kinase C (PKC) signaling in tumor necrosis factor-? (TNF-?)-induced cardioprotection against hypoxia/reoxygenation (H/R) injury. METHODS: Neonatal rat ventricular myocytes were pretreated with TNF-? or sodium nitroprusside (SNP) or L-arginine (L-Arg), respectively, for 12 h and then subjected to continuous hypoxia for 12 h, followed by reoxygenation for 6 h. The manganese superoxide dismutase (Mn-SOD) activity of the cells was measured after H/R. Myocyte injury was determined by the release of lactic dehydrogenase (LDH). RESULTS: TNF-? (10~5 (U/L)) significantly increased the Mn-SOD activity and decreased release of LDH from ventricular myocytes. The cardioprotection against H/R injury was induced by the pretreatment with SNP (5 ?mol/L) or L-Arg (5 mmol/L), which was blocked by ODQ (10 ?mol/L), the specific sGC inhibitor, and Chel (5 ?mol/L), the specific PKC inhibitor. Pretreatment with L-NAME (100 ?mol/L), ODQ, Chel, antoxidant 2-MPG (400 ?mol/L) or tyrosine kinase inhibitor genistein (50 ?mol/L) attenuated the increased Mn-SOD activity and reduced LDH level induced by TNF-?. CONCLUSION: The results suggest that NO may play a role in TNF-?-induced cardioprotection, which is mediated by sGC and PKC. [

OBJECTIVE:To provide reference for rational use of antibiotics to treat Pseudomonas aeruginosa (PA) infection in the clinic. METHODS:Resistant rate of PA in our hospital during 2011-2015 were analyzed retrospectively. Antibiotics use densi-ty(AUD)of 10 commonly used antibiotics were analyzed statistically,and the correlation of resistant rate with AUD was investi-gated by Spearman correlation analysis. RESULTS:One thousaud and eleven strains of PA were isolated in our hospital during 2011-2014,detection rate of PA always occupied the top 5 place. Top 3 antibiotics in the list of AUD were levofloxacin,ceftazi-dime,cefoperazone sodium and tazobactam sodium. AUD of piperacillin sodium and tazobactam sodium,levofloxacin,ciprofloxa-cin and meropenem were positively correlated with resistant rate of PA(r were 1.000,0.900,1.000,1.000,P<0.05). AUD of ce-foperazone sodium and tazobactam sodium were negatively correlated with resistant rate of PA(r=-0.900,P<0.05). AUD of imi-penem and cilastatin sodium,ceftazidime,gentamicin,aztreonam and amikacin had no correlation with resistant rate of PA(P>0.05). CONCLUSIONS:There is correlation between AUD of antibiotics and resistant rate of PA. It is of important significance to detect resistant rate of PA and the use of antibiotics regularly. Antibiotics should be selected cautiously in accordance with bacterial monitoring data,results of drug sensitivity tests,the amount and resistant rate of antibiotics,etc,in order to reduce resistant PA.

Background Experimental data have shown tnat polymorpnisms in tne angiotensm-converting en- zyme 2(ACE2)gene are related to echocardiographically determined parameters of left ventricular mass,structure or function in the general population whether ACE2 genotype influences the effect of angi0tensin Ⅱ receptor blocker which improve left ventricular remodeling and function is unknown.Objective To investigate the association be- tween ACE2 gene G9570A polymorphism and the effect of irbesartan on left ventricular structure and function in hy- pertensive patients.Methods Two hundred and five male patients and 190 female patients who were preliminaryly diagnosised with mild and moderate essential hypertension were treated with irbesartan for 48 weeks with initial dose of 150 mg/d and titrated to 300 mg/d to reach the targed BP.Gene polymorphisms of ACE2 G9570A were detected by PCR-RFLP methods.The association between changes in the SBP,DBP,parameters of left ventricular struc- ture and function and genotypes of the ACE2 gene locus were analyzed.Results Irbesartan reducted in blood pres- sure in all patients(P
