Objective To evaluate the value of evoked potentials (EP) in diagnoses of minimal hepatic encephalopathy (MHE) for liver cirrhotic patients without overt hepatic encephalopathy (OHE). Methods A blind and self control study was conducted in 114 liver cirrhotic patients without OHE. All patients were tested for MHE by the number connection test-A(NCT-A), digit symbol test (DST), visual evoked potentials (VEP), brain-stem auditoru evoked potentials (BAEP), short latency somatosensory evoked potentials (SSEP), P300 auditory event-related potentials (P300ERP). MHE was identified when the NCT-A or/and DST was abnormal. The positive rate was compared among VEP, BAEP, SSEP and P300ERP for their reliability and validity in diagnosis of MHE. Results Of 114 patients, 60 patients were found with MHE (52. 6%), which was positively correlated with Child-Pugh classifications (r=0. 278, P = 0. 003). The positive rate was found 17.5% in VEP, 29.8% in BAEP, 38. 6% in SSEP and 57. 0% in P300ERP. There was no significant difference in diagnosis of MHE between P300ERP and NCT-A+DST (X2 =0. 432,P = 0. 511). The sensitivity of VEP, BAEP, SSEP or P300ERP for diagnosis of MHE was 13. 3%, 41. 7%, 46. 7% or 73. 3%, respectively, whereas the specificity was 77. 8%, 83. 3%, 70. 4% or 61. 1 %, respectively. The receiver operating characteristic curve revealed that the best sensitivity and specificity for the diagnosis of MHE was P300EERP (area under the curve was 0. 672, 95%CI 0. 572 * 0. 773). The agreement of NCT-A+DST with VEP, BAEP, SSEP or P300ERP was 43. 9%, 61. 4%, 57. 9% or 67. 5%. Conclusions P300ERP is a sensitive and specific method for the diagnosis of MHE. which can serve as a supplement but not instead of NCT-A+DST.

Aim To evaluate the effects of fibrinolytic enzyme FⅡ from agkistrodon acutus venom on an experimental model of kidney thrombus induced by lipopolysaccharide(LPS). Methods The model of microvascular thrombosis in the rabbits kidney was performed by the method of Hermida, which was induced by infusing LPS. Treatments were begun simultaneously with LPS infusion, through the contralateral marginal ear vein. Six different groups were established: NS 10 ml?h~-1 was infused as the negative control group, urokinase ~20 000 IU?kg~-1 ?h~-1 as positive control group, FⅡwas infused with the dosage of 0.1(Low-dose), 0.3 (medium-dose),0.6 (high-dose) mg?kg~-1 ?h~-1 . The further rabbits, which were given neither LPS nor FⅡ, were infused with saline solution through both marginal ear veins. Kinney sections were examined for the presence of fibrin microthrombi. The measurement of FDP concentrations was used to assess the degradation of microvascular thrombosis. Results Intense fibrin deposition was also detected and FDP concentrations were (78.21?4.79)% and (84.27?6.21)% at 2 and 6 hours after LPS administration in LPS-control group. Little fibrin deposition was detected and FDP concentration also increased in urokinase control group. A lot of fibrin deposition was detected in Low-dose FⅡ group,little fibrin deposition was detected in medium-dose FⅡ group, and no fibrin deposition was detected in high-dose FⅡ group. Additional all doses of FⅡ led to a significant increase in FDP concentration as compared with LPS-control group (P

Objective To study efficacy and safety of cilazapril in treating patients with essential hypertension.Method 115 patients with hypertension were divided randomly into two groups:59 were treated with cilazapril and 56 were treated with enalopril.All the patients were washed out for one week,then took 2.5 mg cilazapril or 10 mg enalapril once a day in each group respectively for 8 weeks.If blood pressure was not reduced 2 weeks later,hydrochlorothiazide was added. Result The effective rate of cilazapril and enalapril was 89.8% and 91.1% respectively.The SBP and DBP reduced from 153±15 mmHg and 104±9 mmHg to 131±11 mmHg and 91±8 mmHg respectively in cilazapril group,and from 155±12 mmHg and 102±10 mmHg to 139±14 mmHg and 90±9 mmHg respectively in enalapril group.There were no significant differences in two groups. No side effects were observed in two groups. Conclusion Cilazapril is an effective and safe agent in treatment of mild and moderate essential hypertesion.

Ulcerative colitis (UC) is a chronic inflammatory disease and its involvement area in colon is influenced by a complex network of gene interactions.We analyzed the weighted gene co-expression networks in microarray dataset from colonic mucosa of patients with UC and identified one gene co-expression module that was highly associated with the progression of involved area in UC colon (Pearson coefficient=0.81,P＜0.0001).In total,523 hub genes in this module were found to be involved in immune system process after enrichment analysis in Gene Ontology.By the STRING and Cytoscape analysis,we observed that interleukin-8 (IL-8) and matrix metalloproteinase-9 (MMP-9) were centered in the network of hub genes.We then detected the expression of IL-8 and MMP-9 in mucosa from left-sided colon of patients using quantitative PCR and immunofluorescence assay respectively.Both quantitative PCR and immunofluorescence assay revealed the expression levels of IL-8 and MMP-9 were significantly different among the healthy controls,left-sided colitis group and pancolitis group (P＜0.05).IL-8 and MMP-9 were detected with an enhanced expression in pancolitis as compared with left-sided colitis and healthy controls,respectively (P＜0.05).This study demonstrates that immune system process is indispensable in the progression of disease in colon,and identifies that IL-8 and MMP-9 play potential critical roles for the progression.

We report one case of pediatric acute myeloid leukemia type 2 (AML-M2) who presented with karyotypic aberration of trisomy 21 with the t(5;ll) chromosomal translocation.The patient achieved complete remission after two cycles of chemotherapy of daunorubicin,cytarabine and etoposide.Then,follow-up cytogenetic analysis from bone marrow cell cultures demonstrated a normal karyotype of 46,XY.After 9 years,the patient relapsed and the karyotypic abnormalities of trisomy 21 with t(5;ll) reappeared.It was concluded that trisomy 21 with t(5;11) is a new unfavorable cytogenetic aberration in AML-M2.

This study was aimed to evaluate the hemostatic effect and mechanism of action for water decoction of Blumea megacephala (Randeria) Chang et Tseng in order to understand its influence to the liver function. The glass slides method and capillary tube method were used in the measurement of the coagulation time (CT). And the tail-cutting method was used to measure the bleeding time (BT), prothrombin time (PT), activated part clotting live en-zyme time (APTT), thrombin time (TT), content of plasma fibrinogen (FIB), platelet count (PLC), plasma complex cal-cium time (PRT), alanine aminotransferase (ALT) and aspartate transaminase (AST). The results showed that intragastric administration with different doses of water decoction of Blumea megacephala (Randeria) Chang et Tseng (6.7 g·kg-1, 13.4 g·kg-1, 26.8 g·kg-1) can reduce CT and BT of mice. And intragastric administration with different doses of wa-ter decoction of Blumea megacephala (Randeria) Chang et Tseng (4.7 g·kg-1, 9.4 g·kg-1, 18.9 g·kg-1) can produce different degrees of impact on PT, APTT, TT and PRT of rats. Certain dose of water decoction of Blumea megacepha-la (Randeria) Chang et Tseng can reduce ALT and AST. It was concluded that Blumea megacephala (Randeria) Chang et Tseng had the hemostatic effect and its mechanism of action may be through the activation of the intrinsic and extrinsic coagulation system. There was no obvious damage to the liver.
