Objective:To investigate the feasibility of clinical application of HLA-DRB,DPB1 genotyping by PCR-SSP,RFLP for alloge-neic bone marrow transplantation(Allo-BMT) .Methods: Corresponding to each of the DRB alleles, nineteen different pairs of sequence specific primers were used to PCR amplify them from twenty samples in both recipients and donors and their amplified products were directly analyzed on agarose gel. At the same time, a pair of primer was used to PCR amplify the second exon of DPB1 and the restriction fragment length polymorphisms were analyzed on PAGE after their PCR products were separately digested by ten endonucleases. Results: Each DRB was typed in according to its clear and visualized electrophoresis band; the DPB1 genotype was also determined by analysis of all codes representing polymorphism fragment band with a computer. Four couples of recipient and donor were matched. Conclusion:PCR-SSP and RFLP are rapid, accurate and reliable genotyping approaches for Allo-BMT.

According to that Y-chromosomal sequence in characterised by Y-specific repeat DNA family (DYZ1 ), which contain 800-5000 copies, a pair of primers Y3, Y4 is designed to amplify their 446bp long of specific DNA segment by polymerase chain reaction (PCR), so as to detect male fetal cells in materal blood. In this paper male fetal cells in maternal blood can be detected by PCR amplification of unpurified DNA from maternal peripheral blood during various stages of gestation (early, middle, late). Compared with villi, ammotic fluid and deliverd neonate sex their coincident rate are 93%. 100%, 87. 5% respectively among three periods. It is revealed that noninvasive examining fetal cells from peripheral blood of pregnant women for diagnosis of sex-linked inherited diseases is significant valuable.

Objective To investigate re-innervation in the neovaginal mucosa of patients underwent sigmoid colon vaginoplasty in treatment of Mayer-Rokitansky-Kistner-Hauser Syndrome (MRKHS).Methods Biopsies in the upper third of the posterior neovagina were taken in 20 patients treated by sigmoid colon vaginoplasty at 1, 2 and 3 years after surgery, respectively. Protein gene product 9. 5 ( PGP 9. 5 ),vasoactive intestinal peptide (VIP) and neuropeptide Y (NPY) were detected by immunohistochemical method and compared with those in intact sigmoid colon mucosa. Results ( 1 ) Density of nerve fiber:abundant distribution of PGP 9. 5 nerve fibers were observed in the mucosal muscle layer, submucosa, and smooth muscle layer of the neovagina. The nerve fibers of VIP and NPY immunoreactivity were mainly distributed around blood vessels and in the smooth muscles. In the neovagina, the density of nerve fibers of PGP 9. 5 of 17 ± 6 were much more than VIP of 2. 9 ± 1.0 and NPY of 2. 5 ± 0. 8 significantly ( P < 0. 05 ).( 2 ) Expression of PGP 9. 5 in neovagina: at 1 year after surgery, PGP 9. 5 positive expression of 14 ± 4 was significantly lower in the neovagina than 28 ± 7 in the intact sigmoid colon( P < 0. 05 ). However, after 2 to 3 years, its expression displayed an upgrade tendency in the neovagina and was significantly higher at the 3 year postoperatively than that at the 1 years postoperatively ( 22 ± 7 vs. 14 ± 4, P < 0. 05 ). The changes were much more obvious in submucosa. (3) The expression of VIP and NPY in neovagina: at 1 year after surgery, VIP and NPY positive nerve fibers were also decreased in the neovagina when compared with those in the intact sigmoid colon ( 2. 3 ± 0. 7 vs. 5.3 ± 1.4, P < 0. 05; 2.5 ± 1. 1 vs. 5.5 ± 1.1, P < 0. 05 ) . At 2 to 3 years after surgery, the positive VIP fiber showed initially decreased and subsequently increased tendency. The density of VIP of 3.7 ± 0. 7 in the neovagina at 3 years postoperatively was higher than 2. 3 ±0. 7 at 1 years postoperatively (P < 0. 05 ). No significant up-regulation was observed in NPY-positive expression in the neovagina within 3 years after operation. Conclusions Distribution of sensory PGP 9. 5,VIP and NPY immunoreactive nerve fibers was similar to the pattern observed within the intact sigmoid colon wall. The number of nerve fibers in the neovagina decreased after surgery and then increased subsequently within 3 years after surgery.

According to ZFY gene sequence on Y-chromosome, which supposedly codes for the testis determining factor (TDF), a pair of primers F3.2 and F4.2 were designed to specifically amplify 650 bp DNA fragment. The amplified product was electrophoresized on 1.5% agarose gel stained with EB, and then directly visualized under UV. This protocol resulted in constantly producing 650 bp band of the specific product by amplification of 500 pg male genomic DNA and had the same result when mixed with 100 fold amount of female genomic DNA. When this method was used to detect Y-ZFY of chorionic villi and amniotic fluid in 20 samples respectively, its accuracy for determining fetal sex reached 100 percent.

BACKGROUND:With the improvement of hemodialysis technology, the long-term survival rate of maintenance hemodialysis patients has been increased continual y. Nowadays, how to improve the quality of life in maintenance hemodialysis patients has been aroused widespread concern, and gradual y become the reliable indicator for comprehensive evaluation of the effect of hemodialysis. OBJECTIVE: To evaluate the effect of individualized intervention and col ective intervention on quality of life in maintenance hemodialysis patients. METHODS:Eighty maintenance hemodialysis patients, who had accepted more than 3 months of dialysis, were randomly divided into two groups (40 cases in the experimental group and 40 patients in the control group). Al the patients in the control group received 6 weeks of individualized intervention according to the pre-established schedule based on the hemodialysis routine care. Patients in the experimental group also have a period of six weeks of col ective intervention according to the pre-established weekly schedule based on the hemodialysis routine care. The quality of life of the patients was evaluated with MOS 36-item short form health survey and kidney disease quality of life short form before and after intervention. RESULTS AND CONCLUSION:After the intervention, both of the experimental group and the control group achieved significantly greater improvement than before in MOS 36-item short form health survey and kidney disease quality of life short form (P<0.01). The physical impact, overal health, emotional state, emotional impact, social function and energy of MOS 36-item short form health survey in the patients of the experimental group were higher than those of the control group after intervention (P<0.01);and the social quality, sleep, social support and patient satisfaction of kidney disease quality of life short form in the experimental group were higher than those in the control group (P<0.01). The results show that both individualized intervention and the col ective intervention based on the individualized intervention are effective in improving quality of life in maintenance hemodialysis patients and the col ective intervention can better improve the quality of life from physical, psychological and social aspects.

Objective To observe the effect of budesonide/doxofylline on patients with persistent asthma. Methods Sixty patients with moderate asthma were randomly divided into treatment group and control group. Patients in treatment group accepted the inhalation budesonide 400μg/d and doxofylline tablet 0.2 bid po but those in control group accepted the inhalation budesonide/formoterol 160/4.5μg bid. FeNO, sputum eosinophils, PEF and ACT scores were compared between two groups. Results PEF and ACT scores in treatment group were lower to those in control group (P<0.05), whereas the score of sputum eosinophils in treatment group was higher (P<0.05) one month later. There was no significant difference in FeNO between two groups (P>0.05). After three months, sputum eosinophils in treatment group were better than that in control group (P<0.05), whereas there was no significant difference in PEF, ACT scores and FeNO between two groups(P>0.05). Conclusion There is no significant difference in controlling asthma between budesonide/doxofylline and budesonide/formooterol
