Objective To explore the effect of different speed of bladder irrigation after transurethral resection of prostate.Methods 477 cases of benign prostatic hyperplasia,who received transurethral resection surgery were collected.According to the date of surgery,they were divided into observation group(in a single day,249 cases)and control group(double day,228 cases).The normal saline was used in the two groups,and the control group was washed with the conventional bladder irrigation,and the observation group was treated with the early rapid(no speed limit opening)and the routine velocity alternating flushing.The incidence of bladder spasm,the incidence of bladder spasm,the bleeding of bladder and the changes of heart rate and the mean arterial pressure of 24h were compared. Results Urine turned clear time,the total fluid,postoperative 5d red blood cell count of the observation group[(19.8 ± 8.3)h,(44.7 ±6.1)L,(25.8 ±11.3)months/μL]were significantly lower than the control group[(25.4 ±9.0)h, (52.3 ±7.4)L,(33.4 ±10.1)months/μL],the differences between the two groups were statistically significant(t =-6.270,-2.417,-10.459,all P <0.05).The incidence rate of bladder spasm,seizure frequency and duration per capita of the observation group[24.5%,(2.2 ±0.6)times,(15.4 ±4.6)min]were significantly lower than the control group[46.9%,(6.7 ±1.2)times,(27.6 ±5.1)min],the differences between the two groups were statistically significant(χ2 =8.725,t =-13.250,t =-18.066,all P <0.05).The postoperative rinse 1h,2h and 24h heart rate,mean arterial blood pressure had no statistically significant differences(all P >0.05).Conclusion The early rapid and conventional alternating washing method can improve the seizure of bladder spasm after prostatectomy,and reduce the bleeding of bladder.

Objective To comprehensively analyze the effect and various detection indicators of leucocyte depletion suspended red blood cells(RBC) prepared by different storage time and different manufacturers of leucocyte depletion instrument to provide some decision-making basis for peers .Methods Two hundreds and forty bags of suspended RBC(1 ,1 .5 ,2 U) prepared from whole blood by 4 manufacturers were randomly collected and preserved in (4 ± 2)℃ dedicated refrigerator according to different specifica-tions .Then the sterile quick-release connector was used to take 240 leucocyte depletion suspended RBC samples of same specifica-tions and different shelf lives of 0 ,7 ,14 ,21 ,28 ,35 d by different manufacturers .Their capacity ,hematocrit ,leukocyte residues ,plas-ma free hemoglobin content and hemoglobin content were detected ,and the hemolysis rate at the end of shelf life was calculated .Re-sults The effect of leucocyte depletion suspended RBC by the same manufacturer had no statistical difference among different spec-ifications (P>0 .05);the capacity and plasma free hemoglobin content in the same specification had statistical difference among difference among different manufacturers (P<0 .05);the free hemoglobin and hemolysis rate at the end of shelf life in the same manufacturer had statistical difference among different preserving time (P<0 .05) .Conclusion By comprehensive considering the results of indexes of capacity ,hematocrit ,filter time ,free hemoglobin content and hemolysis rate ,our station chose the Shandong Weigao and Fresenius disposable leucocyte depletion plastic bags for ensuring the leucocyte depletion effect ,and safety and efficacy of RBC transfusion .

Objective To investigate the role of oxidized LDL and coronary endothelial dysfunction in the development and progress of coronary heart disease(CHD).Methods 29 patients with unstable angina(UA),25 patients with stable angina(SA) and 20 patients without coronary heart disease(control) were studied.Oxidized low-density lipoprotein(ox-LDL)、 Nitric oxide(NO),and circulating endothelial cells(CEC) were measured in both coronary sinus and peripheral blood during percutaneous coronary intervention(PCI).Results The level of NO in coronary sinus in patients with CHD was lower,while the level of ox-LDL and CEC was markedly higher than those in the control group.In CHD patients,the level of NO in coronary sinus blood was lower,while the level of ox-LDL and CEC was higher than that in peripheral blood.It was no siginificant difference between coronary sinus and peripheral blood was observed in the control group.Conclusion Oxidized LDL not only plays an important role in coronary endothelial dysfunction,but also contributes to the progress in the cornornary heart disease.It may be one of the pathophysiological basis of acute coronary incidents.

1 were also high in DDDs(i.e.high dosage).CONCLUSION: The patients undergoing uterine-incision delivery had a high proportion in using antimicrobial drugs yet the choice of drug kinds was reasonable.However,great attention should be paid to the high dosage of some of the antimicrobial drugs.

Strengthening the construction of open optional courses of medicine in universities is necessary for us to make good use of the teaching resources,to optimize the open optional courses system,and to improve the quality education.This thesis analyzes the problems of open optional courses of medicine in the university by questionnaire.It brings out ways to further improve the construction of open optional courses of medicine in universities.

The research of curriculum tells us that in every university there are two kinds of curriculums.One is noticeable,the other is hidden.Both of them work for the goal of bringing the students up.The witchery of hidden curriculum is that it affects the students continually and secretly.This essay discuses the significance,principle and approaches of the construction of hidden curriculum in higher learning.

[Objective] To develop a method for the determination of thiamazole content in Yingqi Ling Tablets. [Methods] High performance liquid chromatography (HPLC) was used. The chromatographic conditions were: C18 Gravity Column (4.6mm ? 250mm), methanol - water (10:90 ) as mobile phase, flow rate being 1.0mL/min and the detection wavelength at 258nm. [Results] The calibration curve was linear in the range of 0.16 - 0.64?g. The average recovery was 101.01% (relative standard deviation sr = 2.21%). Relative standard deviation of precision test was 1.04% and the content of the sample was 0.4841 mg per tablet (sR = 0.78%). [ Conclusion] HPLC is effective for the determination of thiamazole content in Yingqi Ling Tablets.

OBJECTIVE To investigate the susceptible factors and the methods of prevention and treatment of nosocomial deep fungal infection in intensive care unit(ICU).METHODS The clinical information of 798 patients in ICU was investigated from Jul 2005 to Jun 2007.The risk factors,species,drug-resistance and the methods of prevention of fungal infection were analyzed.RESULTS Fungal infections were found in 137 cases(17.2%).The lower respiratory tract accounted for 72.3% in 137 cases with fungal infection.A total of 180 strains of fungi were isolated,Candida albicans,C.tropicalis and C.glabrata accounted for 43.3%,25.6% and 23.3%.The resistance characteristics to fluconazole,itraconazole,5-fluorocytosine and amphotericin B were relatively weak.The factors related to nosocomial fungal infection were the severity of the underlying disease,long-term use of antibiotics and glucocorticoid and invasive procedure.CONCLUSIONS Proper use of antibiotics and immuno-depressor,reduction of unnecessary operation and early diagnosis are the keys in prevention of systemic fungal infection.

Objective To explore the relationship of the plasma ox-LDL level and endothelium flow mediated vasodilation(FMD)in acute coronary syndrome patients(ACS).Methods From March to October 2004,in the Department of Cardiology,the Fourth PLA Hospital,51 patients with ACS were divided into 2 groups:AMI group(22patients)and UAP group(29 patients).20 subjects with normal coronary angiograms served as the control group.Nitrir oxide(NO)and plasma ox-LDL was measured by spectrophotometer and Sandwich ELISE method,respectively.The brachial arterial hyperemia-induced flow mediated vasodilation(FMD)and sublingual nitroglycerin(NTG)mediated vasodilation were measured by high resolution ultrasound.Results (1)The FMD in ACS group was significantly decreased compared with the control group[(7.2?1.42)、(7.6?1.12)vs(15.46?1.2),P0.05).(2)The No in ACS group was sigificantly lower than that in control group;the NO in AMI group was even lower[(48.46?12.44)、(60.42?10.30)vs(94.72?12.34)?mol/L,P1,which meant ox-LDL was a risk factor;the OR of FMD was
