BACKGROUND: The abnormal changes of hemorrheologic indexes are closely correlated with vascular injury, disorder of microcirculation, thrombosis and its development.OBJECTIVE: To investigate the changes of 25 indexes of hemorheology and whole hemocytes in patients with acute cerebral infarction.DESIGN: A controlled case study.SETTING: Department of Medical Laboratory, Xinxiang Medical College.PARTICIPANTS: Cerebral infarction group: Totally 127 patients with the first attack of acute cerebral infarction were selected from the Department of Neurology, the Second Affiliated Hospital of Xinxiang Medical College from January to December in 2002. The onsetof disease ranged from 4 to 12 hours, and the lesions were confirmed by cranial CT, the diagnostic standard accorded with the diagnostic guidelines for various cerebrovascular diseases formulated by the Fourth National Academic Conference for Cerebrovascular Diseases. Normal control group: Fifty-three healthy physical examinees with normal blood pressure and without diseases of heart,brain and kidney, as well as diabetes mellitus. There were no sigmficant differences in ages and male to femaleratios between the two groups.METHODS: ① Patients in the cerebral infarction group received fibrinogen reduction therapy, they were injected with two pieces of 10 u defibrin on the day of admission, and injected with one piece of 10 u defibrin again on the 3rd, 5th and 7th days respectively. ② Fasting venous blood (5 mL) was drawn with thromboliquine anticoagulated vacuum blood collecting tube,and 2 mL blood was coagulated with EDTA-K2. The whole blood viscosity,whole blood high-sheafing reduction viscosity, whole blood low-shearing reduction viscosity, whole blood high-sheafing relative index, whole blood lowsheafing relative index, equation K value of erythrocyte sedimentation, plasma viscosity, hematocrit, erythrocyte sedimentation, aggregation index of red blood cells (RBC), rigidity index of RBC, deformation index of RBC, counts of while blood cells (WBC) and RBC, mean volume of RBC, mean corpuscular volume (MCV), RBC distribution width (RDW), content of hemoglobin,mean corpuscular hemoglobin content (MCH), mean corpuscular hemoglobin concentration (MCHC), platelet count, mean platelet volume (MPV) and platelet distribution width (PDW) were detected when the shear rate was 200 s-1, 30 s-1, 5 s-1 and 1 s-1 respectively. ③ The above indexes of the patients with cerebral infarction were detected within 24 hours after attack (exacerbation) and at two weeks after treatment (recovery period) respectively.MAIN OUTCOME MEASURES: The hemorrheologic and whole hemocyte indexes were compared between the two groups.RESULTS: All of the 127 cases in the cerebral infarction group entered the analysis of results at exacerbation, and 5 of them were not reexamined because of discharge and 122 cases entered the analysis of results at recovery period. All the 53 cases in the normal control group were involved in the analysis of results. ① Except RDW and MCHC, all the other indexes in the patients with cerebral infarction at exacerbation were significantly different from those in the normal control group (P＜0.05, 0.01). As compared with the normal control group, the whole blood low-shearing viscosity, whole blood low-shearing reduction viscosity, whole blood high-sheafing relative index, whole blood low-shearing relative index, plasma viscosity,hematocrit, aggregation index of RBC, WBC count and MCH all returned to normal in the patients with cerebral infarction at recovery period (P＞0.05).② As compared with the exacerbation, the RBC count and MPV were obviously decreased in the patients with cerebral infarction at recovery period (P ＜ 0.05), while the other indexes were similar (P ＞ 0.05).CONCLUSION: Abnormalities of hemorrheologic indexes commonly exist in patients with acute cerebral infarction, which indicates that the abnormalities of hemorrheologic and whole hemocyte parameters may be related to the occurrence of acute cerebral infarction.

Objective To investigate the value of kinetic features measured by computer-aided diagnosis (CAD)for breast MRI.Methods One hundred and sixty four lesions diagnosed pathologically by operation or biopsy comprised the analysis set.Automated lesion kinetic information from CADStream programs for breast MRI was identified.Three CAD variables were compared for benign and malignant lesions: initial phase peak enhancement (greatest percentage of signal intensity increase on first contrast enhanced sequence),delayed phase enhancement categorized by a single type of kinetics comprising the largest percentage of enhancement (washout,plateau,or persistent),and delayed phase enhancement categorized by single most suspicious type of kinetics (any washout ＞ any plateau ＞ any persistent).Morphological characteristics of breast lesions were described according to breast imaging and reporting data system (BI-RADS).Initial phase peak enhancement mean values between benign and malignant breast lesions were compared by using Wilcoxon rank-sum test,delayed phase enhancement categorized by a single type of kinetics comprising the largest percentage of enhancement or by single most suspicious type of kinetics between benign and malignant breast lesions were compared by using Chi-square test.Results There were 72 benign and 92 malignant breast lesions.A total of 123 (75.0％) mass lesions were identified,and the other 41 (25.0％) lesions showed no mass.Thirty lesions were BI-RADS-MRI 2,68 lesions were BI-RADS-MRI 3,43 lesions were BI-RADS-MRI 4,23 lesions were BI-RADS-MRI 5.Initial phase peak enhancement mean values of benign and malignant lesions were 237％ (69％ to 629％)and 336％ (86％ to 793％),respectively.There was no significant difference between benign and malignant lesions in initial peak enhancement mean value (Z =-1.626,P =0.104).Delayed phase enhancement categorized by single most suspicious type of kinetics (any washout ＞ any plateau ＞ any persistent) for benign and malignant lesions were 15,10,47 and 2,3,87 respectively.There was a significant difference between benign and malignant lesions (x2 =23.562,P =0.000).Initial peak enhancement value ＜ 100％ or ≥100％ were 5 and 67 for benign lesions,3 and 89 for malignant lesions,respectively.There was no significant difference between benign and malignant lesions at 100％ threshold (x2 =1.181,P =0.277).Delayed phase enhancement categorized by a single type of kinetics comprising the largest percentage of enhancement (washout,plateau,or persistent) for benign and malignant lesions were 48,6,18 and 47,15,30 respectively.There was no significant difference between benign and malignant lesions (x2 =4.496,P =0.106).Conclusions Of CAD kinetics analyzed,only delayed enhancement categorized by most suspicious type is helpful for the differentiation between benign and malignant lesions.However,there is significant overlap between initial peak enhancement at 100％ threshold or delayed kinetics categorized by largest percentage enhancement types of benign and malignant lesions,so lesion morphologic features should be considered.

Background and purpose:It was reported that zinc ifnger protein 139 (ZNF139) was expressed aberrantly in gastric cancer. But the relationship between ZNF139 and multidrug resistance (MDR) of gastric cancer is still not clear. The purpose of this research was to investigate the expressions and signiifcance of ZNF139, MRP-1, MDR1/P-gp, GST-π in human gastric carcinoma cell lines SGC7901 and SGC7901/ADR. Methods: The expressions of ZNF139, MRP-1, MDR1/P-gp, GST-πwere determined with RT-PCR and Western blot in SGC7901 and SGC7901/ADR cell lines. Then siRNA recombinant plasmid of targeting ZNF139 gene was constructed and imported into gastric cancer cell line SGC7901/ADR, and the expressions of MRP-1, MDR1/P-gp, GST-πwere tested simultaneously. Results:The expressions of ZNF139, MRP-1, MDR1/P-gp, GST-πwere higher in SGC7901/ADR than in SGC7901(P<0.05). ZNF139 was inhibited obviously after siRNA-ZNF139 was transfected into SGC7901/ADR, and expression of MRP-1, MDR1/P-gp, GST-πdecreased(P<0.05). Conclusion:ZNF139 may be invovled in multidrug resistance (MDR) of gastric cancer by up-regulating MRP-1, MDR1/P-gp and GST-π.
