Objective To evaluate the clinical application of HLA matching in highly sensitized recipients of renal allografts.Methods Recipient's panel reactive antibody (PRA) was detected by using ELISA test with Lambda antigen tray (LAT).Donor and recipient HLA classⅠtyping was performed with special monoclonal tray,and HLA classⅡgene typing with micro-sequence specific primers (Micro-SSP).Results There were 104 recipients with anti-HLA class-ⅠIgG antibody,76 with anti-HLA class-ⅡIgG antibody,and 44 with both anti-HLA class-1 and anti HLA class-ⅡIgG antibody respectively in 136 sensitized recipients.HLA class-ⅠIgG antibody positive rate was 11%-97 %,with an average of 49.6%?23.8%;The common public epitopes antibody was not found in each recipient of 13 cases with PRA<20%,but was found in I2 recipients in 44 cases with PRA be- tween 20%-50%,and 39 recipients in 47 cases with PRA>50%.HLA class-ⅡIgG antibody posi- tive rate was 17%-100%,with an average of 28.2%?63.8%.The number of cases of 0,1,2,3, 4 MM was 7 (5.1%),26 (19.1%),47 (34.6%),39 (28.7%) and 17 (12.5%) respectively by the standard of conventional HLA antigen matching;however the number of the recipients with 0,1, 2,3 MM was 31 (22.8%),53 (39.0%),36 (26.5%) and 16 (11.7%) respectively according to the rule of HLA CREGs matching and none with 4 MM.Rates of acute rejection in sensitized recipi- ents with 2MM and 3MM HLA-CREGs were 25.0% and 37.5% respectively and were significantly higher than those with 0MM (P<0.05,<0.05 respectively).Kidney year-survival was decreased when the number of MM of HLA CREGs matching increased.Conclusion The HLA CREGs matching can improve the ratio of well-matched significantly.Good HLA matching can reduce the incidence of acute rejection in sensitized recipients and increase the survival rate of grafts.

Objective: To observe the effect of cilostazol on the ion channel of right ventricular cells in experimental rats, and to explore the ion channel mechanism of ciolstazol for preventing the ventricular arrhythmia in Brugada syndrome.
Methods: Our research was composed of 2 groups: ①Perfusion group, the cells were treated in 4 sub-groups by cilostazole at 1, 2, 5, 50μmol/L respectively, and there were 9, 5, 3, 7 cells were recorded at each sub-group to observe the differences of current density Ito at before and after treatment. ②Oral group, which included 4 sub-groups:Control 1 with 7 rats, Experiment 1 with 5 rats, and Control 2 with 8 rats, Experiment 2 with 6 rats respectively. The differences of current density Ito and ICa,L were studied between each Control and Experiment sub-groups.
Results: In Perfusion group,①with cilostazole 1, 2, 5, 50μmol/L treatment, the current density Ito decreased in all sub-groups, when the self-command voltage at+60mV, the Ito was signiifcantly different in each sub-group at before and after treatment, all P<0.05.②When each command voltage decreasing, the reduction rates of Ito were similar among 4 sub-groups, all P>0.05. In Oral group,①When the self-command voltage from-50mV reached the maximum of+60mV, the Ito was similar between Control 1 and Experiment 1 sub-groups, P>0.05.②When the self-command voltage at+10mV, the current density of ICa,L was slightly higher in Control 2 sub-group than that in Experiment 2 sub-group, P>0.05.
Conclusion: Direct perfusion of cilostazole in right ventricular cells may inhibit Ito in experimental rats, such effect was similar with cilostazole treatment at (1-50)μmol/L. Cilostazole might prevent the ventricular arrhythmia in Brugada syndrome in experimental rats.

For all the time the book Symptomatic Figures of Lip and Tongue(Chunshe Zhenghou Tu)was described as written by Li Jun of Qing dynasty. We made studies on historical records on Li Jun and the features and contents of this book, and proved that Symptomatic Figures of Lip and Tongue was not written by him, but a Chinese medical book written by Japanese.

More than ten bacteriophage of E.coli were isolated from the soil and the dung of the fowl-run, then three of named bacteriophage A, C, D which lysis E.coli virulently were selected to investigate biological characterizations. The results showed that high activities were obtained after the phages incubated at 50℃ for 1 h or 60℃ for 30 min. The phages could be alive at the range of pH from 4 to 12, Ca 2+ or Mg 2+ added to the medium could stimulate the lysis of phages. However, the formation of the plaque could be inhibited obviously by adding sodium citrate to the medium.
