OBJECTIVETo explore the association between C825T polymorphism of G protein beta3 subunit (GNB3) gene and different Hilit types of essential hypertension (EH) in the Uygur nationality of Xinjiang.
METHODSAccording to Uygur medical theories, EH patients (as the EH group) and non-EH patients (as the control group) were assigned to four Hilit groups. The C825T polymorphism of GNB3 was detected in 161 EH patients and 379 non-EH subjects of different Hilit types by using polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) to explore the difference of the genotypes and allelic frequencies and hypertension.
RESULTS(1) In Xinjiang Uygur population, the distribution frequencies of GNB3 C825T polymorphism were in accordance with Hardy-Weinberg (chi2 = 0.871, P = 0.647). (2) There was no statistical difference in the distribution frequencies of three genotypes and two alleles of GNB3 between the EH group and the control group (P > 0.05). (3) There was statistical difference in distribution frequencies of three genotypes between the abnormal Sapra and non-abnormal Sapra group (the sum of abnormal Sewda, abnormal Kan, and abnormal Balhem) (chi2 = 6.905, P = 0.032), especially between the abnormal Sapra and abnormal Balhem groups (chi2 = 10.404, P = 0.006), but there was no statistical difference in distribution frequencies of alleles between the two groups (P > 0.05). (4) In 161 EH patients, there was statistical difference in the distribution frequencies of three genotypes and two alleles between the abnormal Sapra and non-abnormal Sapra group (chi2 = 9.034, P = 0.011; chi2 = 4.701, P = 0.03).
CONCLUSIONSBoth TT genotype and T allele of GNB3 C825T polymorphism might not be associated with EH patients in Xinjiang Uygur populations. However, they were correlated with hypertension patients of non-abnormal Sapra, indicating the pathogeneses of EH with different Hilit types might be different.

Protamine (PRM) is one of the most abundant arginine-rich nucleoproteins in sperm and plays an important role in spermatogenesis. In the late stage of spermatogenesis, the replacement of PRM by histone prompts the closer combination between the nuclear matrix of sperm and nucleoprotein in order for high enrichment and condensation of nuclear chromatin in addition to preventing the sperm genome from mutation induced by internal and external factors. With the development of DNA sequencing techniques, researches on the association between PRM polymorphisms and male fertility are surfacing as a hot field. Many studies show that rs2301365 polymorphism is a risk factor for male infertility and increases the risk of male infertility by 27 - 66%, that rs737008 polymorphism of PRM1 and rs1646022 polymorphism of PRM2 are protective factors against Asian infertility, and that the ratio of PRM1 to PRM2 is intensively associated with male infertility. This review presents an update on the association between PRM gene polymorphisms and male infertility.
