ABSTRACT
【Objective】 To compare the transfusion effects of ABO homotype leukocyte depleted suspended RBC and washed RBC in patients, who present major and minor cross-match incompatibility, DAT+, IAT+ and autoantibody+ . 【Methods】 The hemoglobin and total bilirubin of patients before and after transfusion were detected, and statistical analysis was conducted by IBM SPSS Statistics 22.0 software. 【Results】 34 transfusions were performed in 17 patients with major and minor cross-match incompatibility. Both leukocyte depleted suspended RBC and washed RBC significantly increased Hb level(P0.05), with similar transfusion efficacy(P>0.05). After t, Hb levels(g/L) increased by 11.35±8.07 and 13.94±9.017, and TBIL(μmol/L) decreased by 25.76±88.63 and 6.91±9.39, respectively, after the transfusion of leukocyte depleted suspended RBC and washed RBC per unit. 【Conclusion】 For blood recipients with major and minor cross-match incompatibility, both ABO homotype leukocyte depleted suspended RBC and washed RBC, given in time, were effective. However, washed RBC is secondary choice due to long preparation time and short storage time.
ABSTRACT
OBJECTIVE@#To investigate clinical effect of partly weight-bearing walking and functional exercise immediatly after operation for Achilles tendon rupture(ATR) on function of ankle joint and rate of fragmentation of Achilles tendon, through comparing effect of partly weight-bearing walking and functional exercise immediatly at 2 weeks after operation for Achilles tendon rupture.@*METHODS@#Sixty-four patients with ATR selected from March 2012 to March 2013 were randomly divided into two groups. There were 34 patients in treatment group, including 18 males and 16 females with an average age of 41.4±7.6, they began to do functional exercise and walk on fields with partly weight-bearing at two days after operation; there were 30 patients in control group, including 16 males and 14 females with an average age of 39.9±7.6, and they were immobilized with plaster in plantar flexion at two weeks after operation, and started to do functional exercise and walk on fields with partly weight-bearing at two weeks after operation. Two groups were performed by the same doctor with the same operation. The rate of fragmentation of Achilles tendon, and AOFAS score and complications between two groups were observed and compared.@*RESULTS@#AOFAS score in treatment group at two weeks after operation was 74.3±3.9, which in control group was 71.7±4.2, and had statistical differences between two groups; AOFAS score in treatment group at one year after operation was 93.3±3.9, which in control group was 92.0±4.1, and had no statistical significance. No Achilles tendon fragmentation in treatment group occurred at three years after operation, and 1 patient occurred in control group. Two patients in treatment group occurred complications after operation, and 1 patient occurred in control group, however, there was no statistical significance between two groups.@*CONCLUSIONS@#Functional exercise immediate after operation for Achilles tendon rupture(ATR) patients in the early days, the AOFAS scores is higher than the fixing for two weeks, and does not increase the rate of fragmentation of Achilles tendon and complication after operation, and benefits for function recovery.

Objective To study the molecular mechanism of Bel subtype caused by mutation p.R168W of glycosyltransferase B.Methods Serological test,SSP-PCR and direct sequence the Exon6 and Exon 7 of the ABO gene.Construct a 3D molecular model and predict the structural impact of GTB protein mutations.Results A antigen or B antigen can't be detected on the surface of the propositus' RBC,and only anti-A antibodies were detected in her serum.But serological test indicated her daughter's blood type was a normal B type.SSP-PCR test indicated propositus' ABO gene type is O1 B.By gene sequencing the Exon 6 and Exon 7 of the ABO gene,a ABO Bel allel(c.502C＞T,p.R168W)was discoverd in both the propositus and her daughter.Through the propositus' daughter coexisted Bel gene with normal B gene,her blood type was a normal B type.Conclusions ABO gene c.502C＞T mutations cause Bel phenotypes in patients by reducing the stability of GTB.
ABSTRACT
Objective To construct luciferase reporter vector containing full-length high-mobility group box 1 ( HMGB1, GenBank NM-010439) promoter for the screening of medicine. Methods The full-length HMGB1 promoter was amplified by polymerase chain reaction ( PCR) , and then was inserted into GV238 vector to construct plasmid GV238-HMGB1-P-Luc. GV238-HMGB1-P-Luc combined with internal reference plasmid pRL was co-transfected into Hela cells ( GV238-HMGB1-P-Luc group, which served as positive control group) . Plasmid pGL3-basic combined with pRL was co-transfected into Hela cells (pGL3-basic group, which served as negative control group) . Additionally, lipopolysaccharides ( LPS, 0.2 μg/mL) was used as the activator for the positive control group (LPS group), and then sodium butyrate (SB, 10 mmol/L) was used as the inhibitor for LPS group ( SB group) . At the end of experiment hour 24, luciferase activity was detected. Results The results of digestion, amplification, sequencing and identification showed that the full length of HMGB1 promoter was 2 140 bp, and the DNA sequence was correct, without mutation. Luciferase activity in GV238-HMGB1-P-Luc group was increased as compared with that of the pGL3-basic group ( P<0.05) . Luciferase activity in the LPS group was increased ( P<0.01, compared with that of GV238-HMGB1-P-Luc group) , and then was decreased after the administration of SB ( P<0.01, compared with that of the LPS group) . Conclusion A model of luciferase reporter vector containing HMGB1 promoter has been successfully constructed. Its activity can be increased by LPS, and then is in hibited by SB. The model can be used for further screening of medicine with the activities of regulating HMGB1 promoter.
