To achieve efficient peripheral blood stem cell harvest (PBSCH), a simple method to monitor peripheral blood stem/progenitor cells was evaluated. The Sysmex XE-2100 hematology analyzer with an immature information (IMI) channel was used to identify and count the hematopoietic progenitor cell (HPC). Twenty-five donors mobilized with G-CSF in allogeneic and 11 patients in autologous peripheral blood stem cell transplantation (allo-PBSCT and auto-PBSCT) were involved. The HPC, CD34(+) cell and CFU-GM in the peripheral blood and leukapheresis samples were detected during mobilization and harvest. The results showed that HPC amount had a positive correlation with both the CD34(+) cell and CFU-GM in the peripheral blood. The peripheral blood hematopoietic stem/progenitor cells in allo-PBSCT donors remarkably increased on day 5 of the mobilization, followed the leukocytes increased. However, a fast increase of hematopoietic stem/progenitor cells was earlier than leukocytes in the peripheral blood. The HPC positively correlated with the CD34(+) cell or CFU-GM in the PBSCH. On the days of collection, the count of HPC and CD34(+) cell in peripheral blood was highly correlated with the CD34(+) cell yield. It is concluded that HPC as an estimate of progenitor cells in collected blood sample could be used to determine the optimal time of PBSCH and minimize the risk of missing an adequate harvest.

To evaluate the hematopoietic stem/progenitor cell apheresis effect of Cobe Spectra (Version 6.1) and Fenwal CS 3000 Plus cell separators, fourty-two procedures on twenty donors using Cobe Spectra cell separator and twenty-two procedures on sixteen donors using Fenwal CS 3000 Plus cell separator were retrospectively analyzed. The number of CD34(+) cells collected, the collection efficiency (CE) of CD34(+) cells and the contaminations of red blood cell and platelet in the stem/progenitor cell products of two devices were compared. The results showed that there were no significant differences in the total number of CD34(+) cells collected and the CD34(+) cell CE between the two devices. There were positive correlations between the count of peripheral blood cells including leukocyte, monocyte, hematopoietic progenitor cell and CD34(+) cell after mobilization and the total number of CD34(+) cells collected. The stepwise multiple variable analyses revealed the peripheral blood stem/progenitor cell count emerged as the only significant independent predictive factor for CE. A negative correlation was seen between the peripheral blood monocyte count and the CD34(+) cell CE for the Fenwal CS 3000 Plus. The Fenwal CS 3000 Plus product contained more red blood cells than that of the Cobe Spectra. The decrease in the peripheral platelet count after Fenwal CS 3000 Plus apheresis was also greater. It is concluded that collection efficacy of Cobe Spectra (Version 6.1) and Fenwal CS 3000 Plus was similar. Cobe Spectra shall be used preferably to assure higher CD34(+) cell CE at a high peripheral blood monocyte count. The Cobe Spectra cell separator is better for the donors with mismatched blood type and the donors with thrombocytopenia.

In order to explore the dormancy physiological and biochemical mechanism of Paris seeds, the seed embryo growth courses, and the dynamic change of 5 enzymes, include SOD, POD, CAT, MDH, G-6-PDH were measured during variable temperature stratification. The results indicated that Paris seeds embryo grew quickly after 40 d in warm-stratification (18 ± 1) °C, at the meantime the metabolic activity was significantly strengthened. These facts showed that Paris seeds turned into physiological after-ripening process. After 60-80 d, the morphological embryo after-ripping process basically completed, and the following cold-stratification (4 ± 1) °C furthered Paris seed to finish physiological after-ripening. After 40 d, the activity of MDH decreased while G-6-PDH increased significantly. This showed that the main respiratory pathway of seed changed from TCA to PPP, which benifited breaking seed dormancy. In the whole period of stratification process, the activity variation of SOD and CAT was insignificantly and the activity of POD was enhanced significantly after shifting the seed in cold stratification process. This showed that SOD, CAT had no direct effects on breaking Paris seed dormancy but keeping the seed vigor, while the POD might involve in the process of Paris seed dormancy breaking.

OBJECTIVETo study genic mutation of androgen receptor in hypospadias in Chinese.

METHODSNinety-two patients with hypospadias were selected for the AR gene study (penile 33, scrotal 49, perineal 10; cryptorchidism 15, micropenis 34, indirect hernia 3, augmentation of breast 2, other deformities 8; posses family history 23) while 93 health men as the control. The DNA was collected from 5 ml venous blood by using the method of phenol/chloroform, and quantified with the agarose gel electrophoresis. The 2-8 exons of AR genes were directly sequenced with a PCR technique. The locus of mutation,the change of amino acid caused by genic mutation and the functional influence of target organ were also analyzed.

RESULTSThere were 4 mutations found from the ligand binding domain of AR: exon 4[1 locus:664(ATT-->ACT] and exon 7[3 locuses: 840(CGT-->CAT),855(CGC-->CAC),859(CTC-->CTA)] in experimental group. The amino acid change of Iso664Thr may te the first findings in the world. The mutation of 859(CTC-->CTA) didn't cause the change of the code amino acid. The main clinical symptoms of exon 4[664(ATT-->ACT) were micropenis, slight hypospadias and augmentation of breasts. The exon 7[840(CGT-->CAT), 855(CGC-->CAC)]was showing micropenis and severe hypospadias. The last mutation [859(CTC-->CTA)] of exon 7 showed mild hypospadias.

CONCLUSIONSThe rate of exon 2-7 mutations of the androgen receptor was 4.3%. The mutations were concentrated on ligand binding domain(exon 4-7), and the main phenotypes were hypospadias accompanying with micropenis found in our experimental group.
