Objective To study the therapeutic effects of blood component transfusions on acute leukemia complicated with DIC.Methods The blood component transfusions were mainly used to treat 11 patients with acute aranulocytic leukemia and acute lymphatic leukemia complicated with DIC.Results Three cases were cured,one case were obviously effective,two were improved and five were ineffective,which the total effective rate was 54 5% .Conclusion Early diagnosis and blood component transfusions in timely are effective methods to treat the acute leukemia patients complicated with DIC

Objective To evaluate the influence of extraocular counterpulsation on ocular fundus blood vessels using high-frequency color Doppler ultrasonography. Methods Twenty-one patients with ischemic optic neuropathy were treated with extraocular counterpulsation. During treatment, the Doppler spectra were detected with high-frequency color Doppler ultrasonography. The peak systolic velocity (PSV), end diastolic velocity (EDV) and resistance retinal index (RI) of central retinal artery and posterior ciliary artery were measured instantly before treatment and 1 min,5 min and 15 min after treatment. Results The instant PSV and EDV of central retinal artery and posterior ciliary artery were significantly increased (P＜0.05) after treatment, then decreased gradually. Fifteen min after treatment ,they returned to the level before treatment. Conclusions We can observe the changes of ocular fundus blood vessels noninvasively on high-frequency color Doppler ultrasonography. The method may be regarded as one of the basis for evaluating the effect of extraocular counterpulsation.

Objective To explore the role of Epstein-Barr virus (EBV) infection in the etiology of drug eruption. Methods PCR-Southern blot was used to detect EBV-specific DNA fragment BamH I -W in peripheral blood mononuclear cells of 32 patients with drug eruption and 30 age- and sex-matched normal controls. The mRNA expression of EBV lyric gene BZLF1 in EBV DNA-positive samples was measured by RT-PCR and Southern blot. ELISA was performed to detect EBV virus capsule antigen (VCA)-specific IgM. Results The positivity rate of EBV DNA was significantly higher in patients with drug eruption than in normal controls (78.13% (25/32) vs 10.00% (3/30), P < 0.01), while no significant difference was noted between patients with severe and mild drug eruption (P > 0.05). The expression of BZLF1 mRNA was detected in 3 out of 25 EBV DNA-positive patients; of the 3 patients, 1 suffered from mild drug eruption, and 2 from severe drug eruption. EBV VCA-specific IgM was observed in 6 of 32 patients with drug eruption, but not in any normal controls. No significant difference in the positivity rate of EBV VCA-specific lgM existed between patients with severe and mild drug eruption (P > 0.05). Conclusions There is an active infection of EBV in patients with drug eruption. EBV infection is probably an environmental factor affecting the development of drug eruption.

and 98.6% (436/442), respectively. Conclusion The ELISA based on fusion viral capsid proteins is sensitive, specific and accurate method for determining antibodies to VCA of EBV for both clinical diagnosis and epidemiology studies.

[Objective] To evaluate the results of open reduction with bone autografting and calcaneus reconstruction with internal fixation in treatment of intra-articular calcaneus fracture. [Methods]From January 2005 to May 2007, 17 cases/19 feet of intra-articular calcaneus fractures received treatment of reconstruction plate and bone autografting, with 15 male/18 feet, 2 female/ 2 feet. Patients’ age ranged from 19 to 67 years (mean, 37.5 years). Fracture occurred in left side in 9 cases, right in 6 cases, both sides in 2 cases. All patients received treatment of open reduction with bone autografting and calcaneus reconstruction with internal fixation.[Results]All the patients achieved bone union. One stage union was achieved in 15 feet. Poor blood-supply was found in 3 feet and bone union was achieved after systematic treatment. Wound exudation was found in 1 feet, and bone union was achieved after dressing change treatment. All patients were followed up for an average of 19.7 months (10-38 months). The average union time was 2.5 months, without infection found.X-ray and CT were used to measure Bhler angle, width and axial length, all the indexed showed significant difference (P

Objective:To investigate the relationship between the plasminogen activator inhibitor 1(PAI 1) gene polymorphism and cerebrovascular disease and whether it played an important role in the pathogenesis of cerebrovascular disease Methods:The 4G/5G allele polymorphism in the PAI 1 gene promotor region were genotyped by polymerase chain reaction (PCR) from peripheral blood leukocytes from 60 normal controls, 65 patients with acute cerebral infarction and 31 hypertensives complicated with cerebral hemorrhage Their plasma PAI 1 activity were assayed by ELISA Results: The plasma PAI 1 activity level in the CI group was significantly higher than those in the other two groups PAI 1 level was significantly higher in 4G allele homozygous than both those in 4G/5G heterozygous and 5G homozygous Although PAI 1 level was higher in 4G/5G heterozygous than that in 5G homozygous, the difference had not reach statistically significant There were significant differences between acute cerebral infarction PAI 1 gene polymorphism and controls (P0 05), and PAI 1 levels of the 4G/4G genotype among female patients with CI were higher than those of the male patients with CI of the same genotype Conclusion: The results suggest that PAI 1 gene polymorphism may be a susceptible factor to acute cerebral infarction in Chinese, and 4G allele homozygous genotype may be the major risk factor of acute cerebral infarction, especially it may be an independent risk factor of female CI patients

ObjectiveTo evaluate combined pneumatic lithotripsy and vacuum suction during ureterorenoscopy.MethodsCombined pneumatic lithotripsy and vacuum suction during ureterorenoscopy was conducted for 52 cases of urolithiasis with the average age of the patients 36 years old.There were 3 cases of renal stone,9 upper ureteral stone,12 middle ureteral and 28 lower ureteral stone.The average surface area of the stones was 79 mm2.ResultsThe average operation time was 31 min and the fragmentation in situ 100.0%.The stone upward displacement rate was 1.7%.Fragmentation of the stone has been incomplete in 2 cases and ESWL was instituted.49 patients have been followed up for 1～3 months and the stone clearance rate was 96.0%.ConclusionsThe procedure would reduce the high instillation pressure which might cause upward displacement of the stone and liquid reflux to the renal parenchyma.The vacuum pressure set to -0.2～-0.4 bar is the most ideal.
