Objective:To summarize the patient profiles and therapeutic efficacies of ABO-incompatible living-related kidney transplantations at 19 domestic transplant centers and provide rationales for clinical application of ABOi-KT.Methods:Clinical cases of ABO-incompatible/compatible kidney transplantation (ABOi-KT/ABOc-KT) from December 2006 to December 2009 were collected. Then, statistical analyses were conducted from the aspects of tissue matching, perioperative managements, complications and survival rates of renal allograft or recipients.Results:Clinical data of 342 ABOi-KT and 779 ABOc-KT indicated that (1) no inter-group differences existed in age, body mass index (BMI), donor-recipient relationship or waiting time of pre-operative dialysis; (2) ABO blood type: blood type O recipients had the longest waiting list and transplantations from blood type A to blood type O accounted for the largest proportion; (3) HLA matching: no statistical significance existed in mismatch rate or positive rate of PRA I/II between two types of surgery; (4) CD20 should be properly used on the basis of different phrases; (5) hemorrhage was a common complication during an early postoperative period and microthrombosis appeared later; (6) no difference existed in postoperative incidence of complications or survival rate of renal allograft and recipients at 1/3/5/10 years between ABOi-KT and ABOc-KT. The acute rejection rate and serum creatinine levels of ABOi-KT recipients were comparable to those of ABOc-KT recipients within 1 year.Conclusions:ABOi-KT is both safe and effective so that it may be applied at all transplant centers as needed.

Objective Screening the immune polypeptide sequence of toxoplasma (Tg) CDPK5 gene ,which were synthesized and then immunized the New Zealand white rabbit to prepare antiserum ,and identification its function .Methods Bioinformatics a‐nalysis was used to determine the immune peptide of Tg CDPK5 sequence ,which were artificially synthesized to immune white rab‐bit to prepare antiserum .The titers of antibodies were determined by ELISA and the polyclonal antibodies were verified with CD‐KP5 antigen by Western blot .The sub‐cellular localization of Tg CDPK 5 were obtained by immunofluorescence assay .Results 17 bp peptide sequence from the Tg CDPK5 N‐terminal were chosen as immune polypeptide by bioinformatics analysis .Synthetic pep‐tide were used to immune rabbit to obtain polyclonal antiserum .The result showed that the titer of the obtained ployantibody were 1∶640 000 ;Western blot demonstrated that the antiserum could specifically recognize Tg CDPK 5(75 .4 × 103 );Immunofluores‐cence assay revealed this antibody could specifically recognize the endogenous Tg CDPK 5 of Toxoplasma gondii .Conclusion Ac‐cording to the analysis of Tg CDPK5 sequence information ,this study successful obtained Tg CDPK5 polyclonal antibody .

OBJECTIVE@#To explore the clinical signification of screening 16 target deafness mutations in GJB2, GJB3, SLC26A4, WFS1 and mitochondrial DNA 12S rRNA in 135 children patients with non-syndromic sensorineural hearing loss (NSHL) in Zibo City, Shandong province.@*METHOD@#Peripheral blood samples of 135 subjects in the study diagnosed as NSHL were collected; Polymerase chain reaction (PCR) and direct sequencing were used to analyze the 16 mutation spots.@*RESULT@#Sixty-two cases of 135 patients (45.9%, 62/135) were found out to be carries of at least one pathogenic gene mutation. Among them, 24 cases (17.8%, 24/135) had two mutated alleles (homozygote and compound heterozygote), and 38 cases (28.1%, 38/135) were single mutant carriers. Among all the children patients, 30 cases (22. 2%, 30/135) had SLC26A4 mutations, and 19 cases (14.1%, 19/135) had GJB2 mutations. In the study 86 Mutant alleles were detected, and the allele frequency of SLC26A4 c. 766_2A > G and GJB2 c. 235delC was 11.11% (30/270) and 8.5% (23/270) respectively. The allele frequency of SLC26A4 c. 2168A > G and WFS1 c. 2158A > G is 2.6% (7/270).@*CONCLUSION@#SLC26A4 mutation is the primary cause of the patients with NSHL in this study, and GJB2 mutation is the secondary. The most common mutant form is c. 766_2A of SLC26A4, and the second is c. 235delC of GJB2. GJB3 and WFS1 mutations were detected, whereas mtDNA mutations were not found out in this study.

Objective To analyze the infection sites of pseudomonas aeruginosa (PAE) isolated from patients in hospital ,and in‐vestigate their drug resistance situation ,in order to provide reference information for clinical use of antibiotics rationally .Methods The sample distribution of PAE between January 2012 and December 2013 were retrospectively analyzed .And the resistance rates of PAE to antibacterial drugs from different sites of patients were statistically compared .Results The isolation rate of PAE in re‐spiratory tract was the highest ,accounting for 74 .1% ,closely followed by isolation rate in urine and wound secretion .The resist‐ance rate of PAE to antibacterial drugs in these three kinds of specimen is statistically different (P<0 .05) .The resistance rate of PAE is high in respiratory tract ,and low in wound secretion .Conclusion The pseudomonas aeruginosa infection is mostly common‐ly found in respiratory tract ,and has the highest drug resistance rate .The choice of antibacterial drug should be made according to the infection sites of patients ,because the resistance rate of PAE in different sites of patients is significantly different .
