Spermatogenesis, a continuous course of cell proliferation and differentiation, depends on reproductive hormones. FSH and LH-induced T are the main hormones regulating spermatogensis. Intratesticular T is one of the key factors in maintaining spermatogenesis, while FSH is just as important for origination and maintenance of normal spermatogenesis. Sertoli cells are the pivot of hormonal regulation. Interestingly, these reproductive hormones also regulate sperm cell apoptosis spermatogenesis. Further studies on the hormonal regulation of spermatogenesis provide a base for the development of safe and recoverable contraceptives for males.

Objective:To explore the relationship between the polymorphisms in gene FGFR1, FGF10, FGFI8 and the nonsyndromic cleft lip with or without cleft palate (NS CLP) in Chinese population. Methods: Genomic DNA was isolated from peripheral lymphocytes of 75 patients with NS CLP and their parents and 75 unimpaired healthy children. The polymorphisms in FGFRI gene rs13317, p. E467K, p. M3691 and p. S393S, FGF10 gene rs1448037 and FGFI8 gene rs4043716 were detected by applying three-dimensional (3-D) polyacrylamide gel microarray technology. The data were performed using statis-tical analysis : the genotype frequenc+ y and allele frequency between patients with NSCL/P and control subjects were performed. Haplotype relative risk (HRR) , family based association test (FBAT) , and transmission disequilibrium test (TDT) in nuclear family were performed. Results: There were no poly-morphism in FGFR1 gene p. E467K, p. M369I and p. $393S site, the corresponding base was all G. The polymorphisms of rs13317 and rs1448037 were detected and their genotype frequency and allele frequen-cy showed no significant difference between 75 patients with NSCL/P and 75 normal children. TDT, HRR and FBAT were also no significant differences. The genotype frequency of gene FGF18 rs4043716 showed significant difference, but allele frequency were no significant difference. TDT, HRR and FBAT were also no significant difference. Conclusion: Our studies suggest an association between gene FGF18 rs4043716 and the NS CLP in Chinese population, and no association among gene FGFR1 rs13317, p. FA67K, p. M3691, p. S393S and gene FGF10 rs1448037.

The circulating renin-angiotensin system (RAS) is well known for its role in the maintenance of blood pressure and electrolyte and fluid homeostasis. However, other local angiotensin-generating systems than the circulating RAS have been found in numerous tissues. The male reproductive system including the testis, epididymis, and prostate has several sites of intrinsic RAS activity. The local RAS in these tissues can be responsive to androgens, fat acid, drugs, and hypoxia. There has been evidence for the involvement of the RAS not only in male reproduction, but also in the development of prostate disease. Besides, the assessment of the local RAS activity may be helpful to the early diagnosis of tumor in the male reproductive system.

OBJECTIVETo investigate the effect of Trx-LHRH, a new GnRH crasis protein, on antibody production and male reproductive function.

METHODSTrx-LHRH produced in vitro with a new crasis gene which crasised Trx gene and GnRH gene together, was used as vaccine, and hydroalaminum base as adjuvant, in adult SD rats. After 5 weeks of the first treatment, the same dosage was used again to enhance the effect of vaccine. Antibody level was measured by ELISA, and androgen level by RIA.

RESULTSTrx-LHRH induced successfully the polycolonal antibody at the level of 1 :1 280 approximately 2 560 after 4 weeks of the first treatment, and 1 : 2 000 after 6 weeks of the enhanced treatment. Testosterone level was reduced significantly (P < 0.01) by ELISA, but there was reasonable variation among individuals. Sperm count was also reduced by Trx-LHRH treatment.

CONCLUSIONTrx-LHRH can be used as effective vaccine to induce antibody production, and at the same time, restrain the function of hypothatamas-pituitary-testis axis in vivo.
