Objective To explore the selection and clinical effects of internal or external drainage for upper urinary tract obstruction complicated with acute renal failure.Methods A total of 25 cases of upper urinary tract obstruction complicated with acute renal failure were treated with double J(DJ) tube internal drainage(12 cases,15 times) or percutaneous nephrectomy(PCN) external drainage(19 cases,23 times).15 cases of obstruction were induced by tumor and 10 cases of obstruction induced by benign disease.Results The drainage treatments were performed successfully in 23 cases,with the success rate of PCN and DJ drainage being 86.9%(20/23) and 60.0%(9/15),respectively.Postoperative bleeding occurred in 1 patient with PCN.Conclusions PCN is superior to DJ in the treatment of malignant obstruction,but DJ internal drainage may be the first choice for non-malignant obstruction.

Objective To compare the capabilities of NT-proBNP and BNP in diagnosis of heart failure when complicated with acute cerebral infarction.Methods EP15-A2 document,was employed to verify the precision and accuracy of NT-proBNP and BNP assays on chemiluminescence analyzer Cobas E601 and ADVIA Centaur respectively for 363 samples from patients with chronic heart failure,cerebral hemorrhage and acute cerebral infarction,cerebral infarction complicated with heart failure and normal controls were collected and analyzed by Cobas E601 and ADVIA Centaur,and then determined the changing trends of NT-proBNP and BNP.Moreover,ROC curve was employed in diagnostic value comparison of NT-proBNP and BNP in heart failure groups.Results Cobas E601 and ADVIA Centaur showed good repeatability and accuracy in the detection of NT-proBNP and BNP that both total non-precision were below 3.5％ and the deviations to calibrator were below 3.91％.The level of NT-proBNP an BNP didn't elevate in normal people and cerebral hemorrhage patients.However,they significant elevated in heart failure,acute cerebral infarction and cerebral infarction complicated with heart failure patients (P ＜ 0.01).Their levels were heart failure grade dependent.The levels of NT-proBNP in cerebral infarction complicated with grade Ⅰto Ⅲ heart failure patients were significantly higher than those in chronic heart failure patients,with same heart failure(P ＜ 0.05).However,compared to chronic heart failure patients,the level of BNP in cerebral infarction complicated with heart failure patients didn't elevate significantly until grade Ⅲ heart failure happened.Areas under the ROC curve (AUCs) of NT-proBNP and BNP were botb above 93％ in the diagnosis of chronic heart failure.But for patients who suffered cerebral infarction complicated with heart failure,the diagnostic value of NT-proBNP and BNP were decreased due to cerebral infarction interference.However,the ROC area of BNP was larger than that of NT-proBNP(P ＜ 0.05).Conclusion In the diagnosis of cerebral infarction complicated with heart failure,BNP could be a better choice to determine the degree of heart failure.

Objective To figure out the differentially expressed proteins using proteome technology in leukemia cells induced into different lineages and investigate the application value in early screening of leukemia.Methods With induction of ATRA and NSC67657, the differentiation models was constructed using HL60 cells which has the potentiality to be induced into different lineages by different inducers.Then the differentially expressed proteins in the process of differentiation was separated using two-dimensional electrophoresis and identified using MALDI-TOF MS.The expression of 3 proteins FE1A1, TLE1, NME3 were chosen to be verified in myeloid samples of 5 leukemia patients and 1 normal volunteer using RT-PCR and WB.Results WB showed that NME3 was differentially expressed after both granulocytic and monocytic differentiation( Normal A value = 0.227, NSC67657 A value= 0.079, ATRA A value = 0.064, P ＜ 0.01 ).However, only in 4 of 5 tested patients' myeloid samples, the NME3 protein expression were differentially expressed compared to the normal myeloid sample( Normal A value = 0.082,2 acute leumia transferred from chronic granulocytic leumia A value = 0.274,0.269, acute monocytic leukemia A value = 0.297, one patient with chronic granulocytic leukemia A value = 0.258.There was significant difference between normal and leukemia group, P ＜0.05 ).A value was 0.121 for another patents with chronic granulocytic leukemia The NME3 protein expression was not differentially expressed compared to the normal myeloid sample,P ＞0.05.Conclusions It is still a long way to go for proteome technology from basic research to clinical application.However, the identification of NME3 protein related to differentiation in leukemia patients' myeloid samples had set the foundation for the early diagnosis of leukemia using proteome technology.

AIM:To establish the murine model of oxygen induced retinopathy ( OIR) and to evaluate the inhibition of retinal neovascularization by erythropoietin ( EPO) blockade.
METHODS: Neonates of C57BL/6 mouse ( P7 ) were exposed to 75%±2% oxygen for 5d and return to normal air environment when 12d ( P12 ) to establish oxygen-induced retinal neovascularization model. The neonates were divided into groups, injected with 0. 5μL solution containing 25ng ( group A), 50ng ( group B), 250ng ( group C) of soluble erythropoietin receptor ( EPO-R) or PBS (group D) at P12, P14 and P16 in the right eye. On P17, the litters were sacrificed and their right eyes were enucleated and fixed with 4% paraformaldehyde, made pathological section. The number of breakthrough internal limiting membrane neovascular nuclei was counted with pathological retinal morphology, understanding theproliferative degree of retinal neovascularization.
RESULTS: The pathological sections showed the neovascular cell nuclei which penetrating the inner limiting membrane in intravitreal EPO receptor injection group was reduced statistically than that in PBS injection group, the difference was statistically significant ( P<0.01). And, neovascular nuclei count differences in the
various concentrations of EPO receptor group was statistically significant (P<0. 01). With the EPO receptor concentration increase, neovascular endothelial cells broken through the internal limiting membrane was reduced.
CONCLUSION: Intravitreal injection of soluble EPO receptor can block EPO and improve neovascularization. The new method is expected to become new treatment of ocular neovascular diseases.

Objective To investigate the prevalence of and risk factors for neurosyphilis in syphilitic patients with persistently positive nontreponemal serological tests after regular therapy.Methods Clinical data were collected from 248 syphilitic patients with persistently positive nontreponemal serological tests after regular therapy,and analyzed retrospectively.Univariate analysis,multivariate logistic regression analysis and receiver operating characteristic (ROC) curve analysis were performed to assess factors associated with neurosyphilis.Results Of the 248 patients,25 (10.1％) were diagnosed with neurosyphilis.As univariate analysis showed,the occurrence of neurosyphilis was associated with the degree of decline in serum toluidine red unheated serum test (TRUST) titers (x2 =20.663,P ＜ 0.05) and persistent positive serum TRUST titers (Z =-7.021,P ＜ 0.05),but not with gender,age,stage of syphilis,treatment protocols,initial serum TRUST titers,or the presence or obsence of neurological symptoms (P ＞ 0.05).Multivariate logistic regression analysis revealed that persistent positive serum TRUST titers were a risk factor for neurosyphilis (OR =4.685,95％ CI =2.552-8.601,P ＜ 0.05).ROC curve analysis showed that the best cut-off point of persistent positive serum TRUST titer was 1 ∶ 8 for predicting neurosyphilis,with the area under the curve (AUC) being 0.907.Conclusion Serum TRUST titers are somewhat valuable for predicting neurosyphilis in syphilitic patients after regular therapy.

BACKGROUND: Some studies have revealed that plasma levels of D-dimer and fibrinogen are closely related to blood coagulation status before any occurrence of cardiovascular disease and cerebrovascular disease.OBJECTIVE: To investigate the difference in plasma levels of D-dimer and fibrinogen, two markers of prethrombosis, between elderly patients with cardiovascular or cerebral vascular disease and elderly and younger healthy persons.DESIGN: Case analysis based on patients.SETTING: Cadre ward of a military general hospital of Chinese PLA.PARTICIPANTS: From October 2000 to March 2002, 153 patients with cardiovascular disease and 116 patients with cerebral vascular disease, aging over 60 years, hospitalized in the Second Cadre Ward of the General Hospital of Shenyang Military Area Command of Chinese PLA were selected into this study. Meanwhile, healthy persons with normal results of physical examination conducted in this hospital were selected as controls. Of all the control persons,68 with an age less than 60 years were allocated into the younger control group and the other 98 persons were allocated into the elderly control group.METHODS: On the second day after hospitalization, a venous blood sample was taken from each patient. For those receiving medications of aspirin, their venous blood samples were taken on the 4th day after withdrawal. The plasmas of the samples were measured by using STA Compact, a fully automatic coagulation analyzer(Diagnostica Stago) and the auxiliary kit. The level of D-dimer was detected by employing the immunoturbidimetry assay(ITA) And the concentration of fibrinogen was measured by using the magnetic bead technologies.MAIN OUTCOME MEASURES: The plasma levels of D-dimer and fibrinogen were detected in each group.RESULTS: All the 435 participants entered the statistical analysis procedure. The plasma levels of D-dimer and fibrinogen of elderly control group [(0.91 ±0.51) mg/L and (3.69±1.25) g/L] were significantly higher than those of the younger control group[0.48 ± 0. 15) mg/L and(3.12±0.76) g/L] (t=2.39-2.66, P ＜ 0.05) .The plasma levels of D-dimer and fibrinogen of the elderly cardiovascular group [ (1.35 ± 0. 72) mg/L and(4. 16 ± 1.30) mg/L] and the elderly cerebral vascular group [(1.16±0.98) mg/L and(4.05±1.98) g/L]were significantly higher, as compared with the elder control group and the younger control group( t = 4.23-5.41, P ＜ 0.01 ).CONCLUSION: Compared to the younger control group, the plasma levels of D-dimer and fibrinogen of elderly population increase significantly, especially in those with cardiovascular disease or cerebral vascular disease.

BACKGROUND: Hyperlipemia is one of the important risk factors of coronary atherosclerotic cardiopathy. Great attention has been paid on how to explain the correlation between blood lipid and coronary heart disease and the correlation of characteristics and level of blood lipid with coronary heart disease.OBJECTIVE: To probe into the correlation among the characteristics, the level of blood lipid and coronary heart disease in senile people.DESIGN: Case-control observation and stratified analysis.SETTING: Second Cadre Ward of General Hospital of Shenyang Military Area Command of Chinese PLA.PARTICIPANTS: Totally 105 inpatients were selected in coronary heart disease group, diagnosed as coronary heart disease, tallied with WHO Diagnostic Standard on Coronary Heart Diseases, in Second Cadre Ward of General Hospital of Shenyang Military Area Command of Chinese PLA from January 2001 to January 2002. Totally 99 inpatients, by checked, without coronary heart disease and cerebral vascular disorder were selected in the control in the same period.METHODS: 2 mL venous blood was collected in fasting in the morning and the serum was collected after centrifuged at 3 000 r/minute, for 5 minutes. Auto-biochemical analyzer and enzyme kit were used to determine cholesterol, triglycerin, high density lipoprotein cholesterol and low density lipoprotein cholesterol. Compared with the data in the control, the ranges of cholesterol, triglycerin and low density lipoprotein were calculated successively and divided by 10; at the class intervals of 0.53, 0. 39 and 0.29 mmonl/L, the frequency table was worked out. According to the frequency table, P25 (the 25th percentile), P50 (the 50th percentile), P75 (the 75th percentile) and P90 (the 90th percentile) of cholesterol, triglycerin and low density lipoprotein cholesterol were calculated successively. The stratified groups were divided based on P ＜ 25, P25 to PS0, PS0 to P75, P75 to P90 and ＞ P90, by which, the cases belonging to 5 groups were determined in coronary heart disease group and the control respectively. The exposure factor was determined by ＞ P90, compared with other 4 groups, Menta-Haensecel method was used to calculate x2. If the exposure factor was related with coronary heart disease, the relevant coefficient and 95% confidence interval should be calculated. In accordance with the standards (Proposal on Prevention of Abnormal Blood Lipid and Targets of Abnormal Blood lipid on 2-grade Prevention of Coronary Heart Disease), the cases beyond the targets and morbidity were determined in two groups.MAIN OUTCOME MEASURES: Determination of blood lipid, abnormal cases and morbidity in two groups; cases beyond targets of blood lipid and morbidity; stratified comparisons of percentiles in two groups.RESULTS: According to intention measurement, 204 cases entered result and the control, there was no significant difference in cholesterol, triglycerin cases presented hypercholesterolemia, 34.3% cases hypertriglycerlipidemia and 11. 4% cases low density lipoprotein-hypercholesterolemia. It was indicated that the blood lipid was in the normal range among 64. 8% to 88.6% comparison between the cases with cholesterol ≥5.47 mmonl/L and the cases with cholesterol varied from 3.85 to 4.63 mmol/L, the morbidity of coronary heart disease in the former was 2.98 times as high as the latter (x2 = 6.29, 95% confidence interval was 1.27 -6.98) . In the comparison between the cases with cholesterol ≥ 5.47 mmol/L and the cases with cholesterol varied from 4.64 to 5.05 mmol/L, the correlation with coronary Lipid for 2nd Prevention of Coronary Heart Disease, among the patients with coronary heart disease, cholesterol ≥ 4.68 mmonl/L in 54. 2% cases,triglycerin ≥ 1.70 mmol/L in 34. 3% cases and low density lipoprotein ≥ 2.6 mmol/L in 52. 3% cases.CONCLUSION: For senile patients with coronary heart disease, the satisfactory level of cholesterol is 3.85- 4.63 mmol/L. For those with cholesterol ≥ 5.47 mmol/L, compared with those varied from 3.85 to 4.63 mmol/L, the morbidity of coronary heart disease in the former is possibly 2.98 times as same as the latter(x2 = 6.29, 95% confidence interval was 1.27 - 6.98).

OBJECTIVETo observe the efficacy of preventing constipation by electroacupuncture intervention in ischemic stroke patients at acute stage.

METHODSThree hundred and forty ischemic stroke patients who matched the inclusive criteria were randomly divided into an electroacupuncture (EA) group and a routine treatment group, 170 cases in each one. In the EA group, based on routine western treatment, rehabilitation training and common acupuncture, Tianshu (ST 25) and Zusanli (ST 36) were selected and connected to SDZ-V Hwato brand electric acupuncture apparatus respectively, given stimulation of dense-disperse wave (10 Hz/50 Hz) with electric current of 0.1 to 1.0 mA, once every day and 5 times a week in the first 2 weeks, 2 times a week in the latter 2 weeks. In the routine treatment group, only basic treatment was applied. In the two groups, the course of treatment was 4 weeks and 8 weeks' follow-up was required after treatment. The actual numbers who independently defecated less than 3 times a week after 1 to 4 weeks' treatment and in the 4th and the 8th weeks' follow-up and condition taking laxative medicines during the 12 weeks in the two groups were observed and compared.

RESULTSCompared on the numbers of constipation cases after 1 to 4 weeks' treatment, those in the EA group were all less than those in the routine treatment group [24.7% (42/170) vs. 36.5%(62/170), 18.8% (32/170) vs. 30.6% (52/170), 10.5% (17/162) vs. 27.5% (44/160), 9.3% (15/162) vs. 19.4% (31/160),P<0.05, P<0.001]. In the 4th and the 8th weeks' follow-up, numbers in the EA group were still less than those in the routine treatment group [9.0% (14/156) vs. 18.1% (28/155), 7.7% (12/155) vs. 16.9 (26/154) both P<0.05)]. During the 12 weeks, the number of cases who took laxative medicines in the EA group was less than that in the routine treatment group [21.2% (36/170) vs. 34.7% (59/170), P<0.05].

CONCLUSIONThere is clinical significance to electroacupuncture at Tian-shui (ST 25) and Zusanli (ST 36) coibined with basic comprehensive treatment for preventing and treating constipation symptom in ischemic stroke acute stage.
