【摘要】 目的 初步探討同型半胱氨酸(Hcy)代謝相關酶胱硫醚β合酶(CBS)基因C572T基因突變頻率在廣西河池地區妊娠期高血壓疾病(HDP)發病中的作用。 方法 采用等位基因特異性擴增(ASA)技術檢測63例HDP患者(觀察組)和32例孕期經過順利的正常孕婦(對照組)CBS基因 C572T基因型。結果 HDP組CBS基因C572T T/T、C/T和C/C基因型頻率分別為4.76%、84.13%和11.11%;對照組分別為3.13%、87.50%和9.37%;HDP組C等位基因頻率為53.17%、T等位基因頻率為46.83%,對照組分別為53.13%和46.87%,二者比較,差異無統計學意義(P>0.05)。結論 CBS C572T基因突變頻率與HDP發病無明顯相關性,其基因突變頻率可能不足以構成廣西河池地區HDP發病的獨立遺傳危險因素。

【Abstract】Objective To study the effect of mutation frequency of cystathionine βsynthase(CBS) in patients with hypertensive disorder complication pregnancy(HDP).Methods 63 patients with HDP and 32 healthy pregnant women were pided into HDP group and control group. their C572T genotypes were detected by the technique of Allelespecific amplification (ASA).Results The frequency of CBS gene type T/T,C/T and C/C were 4.76%,84.13% and 11.11% respectively in HDP group,while the control group were 3.13%, 87.50%,9.37% respectively. The frequency of C alleles and T alleles were 53.17% and 46.83% in HDP group,while the control group were 53.13% and 46.87%.there was no significant difference between the two groups(P>0.05). Conclusion There was not significant correlation between C572T and hypertensive disorder complication pregnancy,its mutation frequency may not be independent risk factor for hypertensive disorder complication in He Chi population.

[Abstract] Objective To explore the 5,10-methylenetetrahydrofolate reductase (MTHFR) and 5-methyltetrahydrofolate-homocysteine methyltransferase reductase (MTRR) gene polymorphisms among the Han women in Shouguang City. Methods A total of 787 Han women were recruited. And their oral epithelial cells were collected to extract genome DNA in order to detect gene polymorphisms of MTHFR C677T, A1298C and MTRR A66G using fluorescence quantitative PCR. Then the results were compared with those in other cities in China. Results The frequency distribution of MTHFR C677T among Shouguang women was significantly different with Zhengzhou, Yantai, Zhenjiang, Wuhan, Deyang, Kunming, Huizhou, Qionghai (P < 0.05). The frequency distribution of MTHFR A1298C among Shouguang women was significantly different with Yantai, Zhenjiang, Wuhan, Deyang, Kunming, Huizhou, Qionghai (P < 0.05). The frequency distribution of MTRR A66G among Shouguang women was significantly different with Qionghai (P < 0.05). Conclusion The MTHFR C677T, A1298C and MTRR A66G polymorphism distributions of Han women in Shouguang City are different with other regions, which have visible difference.

導致男性不育的因素很多,包括先天性的發育不良、炎、輸精管梗阻、萎縮、免疫性不育、內分泌失調等,除上述因素外,畸形、無精、少弱精等更為常見。Dong等[27]通過高通量測序技術揭示了人類組織中的環狀RNA譜,對首次發現能產生環狀RNA的1017個宿主基因進行基因本體論(gene ontology,GO)分析,結果顯示,這些基因與發生、運動、減數分裂細胞周期和受精作用等過程相關。李穎[28]的研究顯示,約83%環狀RNA為外顯子來源環狀RNA,而差異表達的環狀RNA在鞭毛、鞭毛軸絲、甲基轉移酶活性等方面富集較多。研究篩選出了hsa_circ_MYO9B、hsa_circ_WHsci(8)等五條環狀RNA,檢測結果發現hsa_circ_WHSCI(8)、hsa_circ_WHSCI(6)、hsa_circ_CAMSAP1三種環狀RNA在弱精組中的表達水平顯著上調。另有學者[29]研究發現,DAZ(Deleted in Azoospermia)家族基因中Boule基因上產生的環狀RNA可能參與調控Boule的生殖特異表達,從而影響男性的少弱精癥。環狀RNA的高穩定性使其在精漿等體液中可以被檢測,未來具有成為男性不育疾病標志物的臨床價值。
