237例孕妇羊水细胞染色体遗传分析

目的：分析孕妇羊水细胞染色体异常情况及其与产前诊断各指征之间的联系,探讨羊水细胞染色体核型检查在产前诊断中的作用。方法通过细胞遗传学方法,对237例具有产前诊断指征的孕妇进行羊水细胞培养,并分析其染色体核型。结果237例孕妇羊水培养成功率98.73%（234例）。检出异常核型11例(4.7%),其中数目异常占异常核型的54.55%（6例）,以三体型为主,结构异常占异常核型的36.36%（4例）。在各项产前指征中,B超检查异常和高龄孕妇受检人数最多,超声指标异常的染色体核型异常检出率最高（8.06%）,与其他组比较差异有统计学意义(P<0.05)。结论羊水细胞的染色体核型分析能够有效地对胎儿染色异常进行诊断,是进行产前遗传诊断的有效手段。     

老年高血压人群同型半胱氨酸与高尿酸血症的相关性

目的 探讨老年高血压人群血浆同型半胱氨酸(Hcy)水平与高尿酸血症(HUA)之间的相关性。方法 选取2018年3至8月在江西省婺源县筛查出的9902例年龄≥60岁的高血压患者,进行体格检查及常规血生化指标检测,根据尿酸水平将研究对象分为HUA组和尿酸正常组,采用多因素Logistic回归分析Hcy水平与HUA发生风险的关系。结果 与尿酸正常组相比,HUA组的高同型半胱氨酸血症发生率(99.9%比98.7%,P<0.001)及Hcy水平[16.8(13.8～21.5)μmol/L比14.4(12.3～17.7)μmol/L,P<0.001]均较高。多因素Logistic回归分析显示,校正影响因素后,高同型半胱氨酸血症组患HUA的风险是Hcy正常组的2.92倍。阈值饱和效应分析显示,Hcy<20μmol/L时,Hcy水平与HUA的发生呈正相关(OR=1.05,95%CI=1.04～1.07,P<0.001);当Hcy≥20μmol/L时,Hcy水平与HUA无相关性(OR=1.00,95%CI=0.99～1.00,P=0.055),对数似然比检验有统计学意义(P<...

准分子激光治疗白癜风的临床疗效与安全性研究

Objective To assess the efficacy and safety of 308 nm excimer laser in the treatment of different types of vitiligo at different stages. Methods A total of 128 patients with vitiligo, who had 317 depigmented patches, were recruited in this study and treated with 308 nm excimer laser once a week for at least 8 weeks. The degree of repigmentation was evaluated and adverse effects were recorded at the end of every treatment and last treatment. Results All patients received efficacy and safety evaluation. Of the 317 patches, 97.5% achieved repigmentation at different degrees, 71.8% got more than 25% repigmentation, and 50.8% got more than 75% repigmentation. The degree of repigmentation increased with the number of treatments. A better response was observed in the lesions on the face and neck than those on the mink and limbs, and in short-duration (<1 year) lesions than in long-duration (≥1 year) lesions. And the lesions on extremities and mueosa showed a poorer response compared with those at other sites. There was no statistical difference in clinical efficacy between active vitiligo and stable vitiligo, or between adults and children. Moreover, the treatment was well tolerated. Conclusion 308 nm excimer laser is effective in the treatment of vitiligo with rapid onset, favorable tolerability and few adverse effects.
