Objective:To examine whether the existence of the donor-and-recipient-derived DNA chimerism in recipient’s plasma can be a predictive marker for the status of transplanted organ.Methods:One hundred and twenty-six female patients who had been transplanted with male kidney were enrolled in the present study.In these female recipients,the SRY1,DYZ11st and DYZ12nd genes on the Y chromosome from the plasma were prospectively examined using reverse transcription polymerase chain reaction (RT-PCR).Results:SRY1,DYZ11st and DYZ12nd sequences were detected in the cell-free blood (plasma) of 97 (77%) of 126 female patients with male kidney.The average time-span when the transplanted kidneys functioned was 8.7 years and 5.4 years among microchimerism-positive and microchimerism-negative recipients,respectively.The frequency of the patients who had acute rejection after renal transplantation was approximately 10% and 28%in microchimerism-positive and microchimerism-negative recipients,respectively.Serum creatinine levels in microchimerism-positive patients were significantly lower than those in microchimerism-negative patients.Conclusion:These results suggest that plasma DNA microchimerism is present in certain patients following renal transplantation and measurement of plasma DNA microchimerism using quantitative RT-PCR might be a useful predictor for the acceptance of transplanted kidneys.

A patient with impaired kidney function after kidney transplantation and received treatment at the First Hospital of Jilin University was retrospective analyzed. The patient was male, 45 years old, and was diagnosed hemolytic uremic syndrome by transplanted kidney biopsy. The patient received cyclosporine A (CsA) as maintenance centered immunosuppression therapy postoperatively. He was admitted because of 1 week acratia followed by 1 day increased serum creatinine level at 1.5 years after transplantation. At 1 day after admission, he was received renal needle biopsy, and underwent 2 days Prednlsolone treatment. After hemolytic-uremic syndrome was diagnosed, CsA was transferred to Tacrolimus (Fk506) with dose of 2 mg/d, and Azathioprine was replaced by mycophenolate, Prednisone was taken orally for 20 mg/d. The function of the transplanted kidney and the change of routine blood tests were observed. After 1 week treatment of the changed Immunosuppression therapy, the function of the transplanted kidney was improved obviously, and the hemoglobin and platelets was decreased during the treatment. The results demonstrated that kidney biopsy is a key method to diagnose hemolytic-uremic syndrome, and adjustment of immunosuppressive agents, replacing CsA with FK506 are effective for postoperative hemolytic-uremic syndrome.

Objective To explore the effects of penile erectile dysfunction (ED) on the quality of life in male renal transplant recipients.Methods 150 cases of male married recipients undergoing renal transplantation were selected randomly.The recipients were divided into ED group (n =63) and non-ED group (n =87) through the IIEF-5 score.The Short Form-36 Health Status Survey (SF-36)and Hamilton Anxiety Scale were used to compare their living quality and the state of mental health between the two groups,respectively.Results The SF-36 scores in ED group in General Health,Vitality,Social Function,Role Limitation due to Emotional Problems,Mental Health were significantly lower than those in non-ED group (P<0.05).There were 13 cases in ED group with anxiety disorders (20.6%),significantly more than in non-ED group (3.4%),P<0.05.Conclusion ED is an important influencing factor for the quality of life in male kidney transplant recipients.

Ulta performance liqiuid chromatography-triple quadrupole tandem mass spectrometry ( UPLC-MS/MS) was used to monitor the relative levels of bufadienolides in toad venom in normal and bensulfuron-polluted groups. Methanol extract of toad venom was separated by UPLC ( ODS-C18 ) using a gradient elution of water contains 0. 1% formic acid and acetonitrile. Mass spectrometry was used in an ESI source operated in positive ion and MRM mode. The parameters in the source were set as follows: capillary voltage 3. 0 kV; sampling cone voltage 30 V; and desolvation temperature 500℃. In this method, external calibrations of 6 standards were typically constructed (R2=0. 9953-0. 9992). The LOD was 0. 42-4. 86 ng/mL. Intra- and inter-day precision was 3. 8%-6. 8% and 4. 0%-8. 8%, respectively. The recovery of standard was evaluated by spiking the standard compound into toad venom. Their average recoveries were 96. 9%-109. 6%, and RSDs were 2. 0%-8. 1%. This method was further employed into monitoring the levels of 36 bufadienolides. The levels of more than 20 bufadienolides were greatly different after bensulfuron pollution, suggesting that the bensulfuron pollution could change the chemical expression pattern of bufadienolides in toad venom.
