Abstract To evaluate the bioavailability of selenium (Se) in Se-yeast to residents with low-Se status, fifty-two youth in a Keshan disease area were randomly divided into three groups, and they were given orally 200 ?g Se daily as So-yeast or sodium selenite, or ordinary yeast for 12 weeks, respectively. Se contents and activities of glutathione peroxidase (GSHpx) in blood were measured at wk 4 and 8 of supplements and 8wk alter the supplements were discontinued. The results show that: 1. the retention of Se in either plasma or erythrocyte is sigificantly higher in Se-yeast than in sodiurn selenite; 2 the effect of Se in Se-yeast is superior to that of sodium selenite for maintaining GSHpx activities; and 3. the relative bioavailabilities of Se in Se-yeast are 556% and 178% when using erythrocyte and plasma Se contents as the response critria, as well as 158% and 116% when estimated by platelet and plasma GSHpx activities. The results indicate that the bioavailability of Se to the residents in a low-Se Keshan disease area is greater when supplemented Se-yeast than selenite.

A three-phase depletion/repletion/depletion feeding study was designed to investigate the changes of Se levels and glutathione peroxidase (GSH-Px) activities in tissues and blood in rats fed for 6 weeks low-Se diet (6 ppb Se) from a Keshan disease area during the supplementations of Se as Ziyang high-Se wheat (1.175 ppm Se) or sodium selenite (dietary Se 219 and 223 ppb respectively) and after the supplements were discontinued, and to evaluate the relative bioavailability of Se in the wheat. The resalts showed that the average bioavailability of Se in high-Se wheat derived from the values at wk 2, 4 and 6 of supplement was close to that in selenite when plasma, erythrocyte, kidney, liver and cardiac Se contents were used as the response criteria, the relative bioavailabilities being 98%, 104%,100%,96% and 101% (sodium selenite = 100%) respectively. The bioavailability was lower for Se in high-Se wheat (70% or 90%) than for selenite when estimated by erythro-cyte or cardiac GSH-Px activities. However, the bioavailabilities of high-Se wheat Se in various tissues were not all the same at different stages of supplement. In addition, the effect of Se in high-Se wheat in maintaining either Se levels in heart, liver and erythrocyte or GSH-Px activity in heart was superior to that of selenite 3 weeks after the Se supplements were withdrawn.

Objective To evaluate the usefulness of mycolic acid for identification of Mycobacterium species using SMIS. Methods One hundred and eighteen clinical Mycobacterium isolates collected from Beijing Tuberculosis and Thoracic Tumor Research Institute through whole year of 2007 were analyzed. The 118 isolates contain 25 isolates of Mycobacterium tuberculosis and 93 non tuberculosis Mycobacterium identified by PNB method. Mycolic acid analysis using SMIS is evaluated for identification of a broad range of Mycobacteria in comparison with 16S rDNA , 16-23S rDNA ITS sequencing to measure the concordance rate and agreement, and verify the concordance rate and agreement among results of mycolic acid, sequencing and PNB in identifying Mycobacterium tuberculosis and non tuberculosis Mycobacterium. Results The concordance rate between mycolic acid method analysis and DNA sequencing is 92% ( 108/118), of which concordance rate in Mycobacterium tuberculosis complex and non tuberculosis Mycobacterium are 95% (35/37) and 90% (73/81) respectively, agreement of both is great( agreement Kappa value is 0. 96). Through retrospective analysis, the concordance of results between SMIS and PNB method analysis is 90% (106/118)and agreement is well( agreement Kappa value is 0. 73 ), the concordance of results between sequencing and PNB method analysis is also 90% ( 106/118 ) and agreement is well (agreement Kappa value is 0. 74 ),despite the identification results of 11 isolates by PNB method are discordant. Conclusion Mycolic acid analysis by SMIS enables rapid identification of a broad range of clinical Mycobacterium species, which could play an important role in polyphasic identification of Mycobacterium species.

Objective To summarize the experiences of 5-year relative living kidney transplantation in the minorities. Methods The clinical data of HLA matching, rejection, survival and causes of death were retrospectively analyzed from 2004 to July 2009. There were 97 blood relative donations, including 1 case of father → son, 1 case of daughter → father, 1 case of mother → son, 24 cases of donation between brother and sister, 2 cases of non-blood relative donors (husband and wife),1 case of inter-ethnics, and the remaining were collateral relative donors. All the donations were voluntary, and all the recipients were minorities and all donors were their blood relatives. There were no mismatch of gene matching of 6 antigenic sites (0 MM) in 1 patient, 1 mismatch point (1 MM) in 2 patients, 2 mismatch points (2 MM) in 5 patients, 3 mismatch points (3 MM) in 10 patients, 4 mismatch points (4 MM) in 21 patients, 5 mismatch points (5 MM) in 39 patients and complete mismatch in 22 patients. Results All donors were discharged after 1 week and followed up for 3-6 months. Blood creatinine was normal and urine protein was negative. Up to July 2009, the conditions of the recipients were as follows: (1) Ninety-one receptors survived after transplantation. The longest survival time was up to 5 years. Among 9 deaths, 1 case died from myocardial infarction, 1 case from hemorrhagic shock and the others from respiratory failure (7 %) ; (2) Two renal grafts lost their functions and the patients restarted dialysis, in whom the preoperative panel reactive antibodies (PRA) of 1 patient was high and the patient had postoperative acute rejection, and the other patient stopped immunosuppressive agents on his own, leading to renal function loss; (3) After transplantation 10 patients had acute rejection, of which 2 cases received methylprednisolone plus OKT3, and the remaining 9 patients were treated with methylprednisolone. All rejections were reversed; (4) Urethral fistula occurred in one case and was improved after 45 days. Three patients had vesicoureteral anastomotic stenosis and were cured surgically. lyrnph leakage occurred in one case and was improved after 2 months. Fourteen patients had lung infection, including 7 mild lung infections which were improved after treatment, and 7 severe lung infections which died from respiratory failure.Other complications included secondary diabetes mellitus (4 cases), urinary tract infection (2 cases),acute renal failure (2 cases), deep venous thrombosis (3 cases), drug-induced liver damage (5 cases),polycythemia (5 cases), hepatitis C (3 cases), chronic allograft nephropathy (3 cases), and all were improved after treatment. Conclusion Comprehensive assessments of the donors and receptors before transplantation are guarantee to successful living kidney transplantation from relative donors; Living kidney transplantation from relative donors has the advantages of good matching, short ischemia period of donated kidney, less rejections and high survival rate of transplanted kidneys.
