42例晚期糖尿病肾病的血液透析治疗

目的:探索出晚期糖尿病肾病患者在血液透析过程中,如何减少并发症,提高对并发症的疗效,延长存活寿命,提高生活质量.方法:除应用一般性碳酸盐透析外,采用不同透析技术,重点对充血性心力衰竭、心包炎、高血压、低血压、贫血以及胰岛素的使用提出了特殊治疗方案.结果:经采取不同透析技术,提高了对并发症的疗效,提高了病人生活质量,降低了死亡率.结论:对晚期糖尿病肾病患者,尽量做到早透析,透析个体化,根据病情采取不同治疗方案,这是减少并发症提高存活率的关键.     

聚合酶链反应标记轮状病毒地高辛素探针的初步应用

目的为探讨聚合酶链反应（ＰＣＲ）技术标记的地高辛素（ＤＩＧ）探针的特异性和敏感性。方法用聚合酶链反应技术制备地高辛素标记的人类轮状病毒（ＨＲＶ）ｃＤＮＡ探针，经ｃＤＮＡ－ＲＮＡ斑点杂交。结果该探针具ＨＲＶ特异性，可检出１０ｐｇ的ＲＮＡ。应用该项技术检测了１２０份婴幼儿腹泻粪样标本，其阳性率为６５％，明显高于ＰＡＧＥ方法（４９．１％）的阳性率。结论ＰＣＲ方法直接制备地高辛素标记的ｃＤＮＡ探针方便、快速、特异性好、标记率高。     

A new haplogroup pattern displayed in Fujian Han in China

Human Y-chromosomal binary polymorphisms have been considered to preserve the paternal genetic legacy and provide evidence on human evolution and the genetic relationships among and demographic history of different populations. To reveal the genetic origin and immigration of the Fujian Han, 13 binary markers on the Y chromosome were used to screen Fujian Han by allele-specific polymerase chain reaction. The results indicated that the M₉G marker was highly prevalent (96.20%), suggesting a significant genetic drift. In addition, M₁₂₂C frequency was only 22.78%, and M₄₅A and M₁₀₃T were default. The distinctive haplogroup frequencies (H₁, H₅, and H_6/7/8) imply that the haplogroup pattern is a relatively ancestral and interim type.

脑血管性痴呆的辨证治疗经验

大脑动脉粥样硬化引起的脑血管性痴呆,以神智痴呆、记忆力减退、表情淡漠、呆滞或欣快感、头晕肢麻、手足瞤动等为特点,属于祖国医学的“文痴”、“语言颠倒”、“癫狂”、“善忘”等病症。中老年以后,肝血衰少,肾精亏损,脑失所养,大病久病,热灼真阴,心肝肾阴阳失调,肝阳化风,挟火挟痰,冲犯脑髓,元神失聪。因此,本病是本虚标实之证。虚者,治以培补真阴,补髓填精;实者,则平肝泻火,涤痰醒神,调气化瘀。文中附病案两例,经两个多月治疗,智力提高、记忆增强、精神活动基本恢复正常、生活自理,好转出院。     

Effects of the Family Check-Up 4 Health on Parenting and Child Behavioral Health: A Randomized Clinical Trial in Primary Care

The Family Check-Up 4 Health (FCU4Health) is an adaptation of the Family Check-Up (FCU) for delivery in primary care settings. While maintaining the original FCU’s focus on parenting and child behavioral health, we added content targeting health behaviors. This study evaluated whether the adapted FCU maintained positive effects on parenting (positive behavior support, limit setting, parental warmth) and child behavioral health (self-regulation, conduct problems, emotional problems). Pediatric (6–12 years) primary care patients with a BMI?≥?85^th%ile (n?=?240) were recruited from primary care clinics in Phoenix. Children were 75% Latino, 49% female, and 73% Medicaid recipients. This type 2 effectiveness-implementation hybrid trial compared families randomized to FCU4Health (n?=?141) or usual care (n?=?99). FCU4Health was delivered over a period of 6 months. This study focuses on a priori secondary outcomes included parenting and child behavioral health targets of the original FCU, assessed at baseline and 3, 6, and 12 months. Significant improvements were found for the FCU4Health condition, compared to usual care, in parenting from baseline to the 3-month assessment [β?=?.17 (.01; .32)]. Parenting predicted improvements in child self-regulation at 6-months [β?=?.17 (.03; .30)], which in turn predicted reductions in conduct problems [β?=?? .38 (? .51; ? .23)] and emotional problems [β?=?? .24 (? .38; ? .09)] at 12 months. Ethnicity and language of delivery (English or Spanish) did not moderate these effects. The FCU4Health can improve parenting and child behavioral health outcomes when delivered in primary care.

高效液相色谱-电感耦合等离子体质谱法测定海鱼中无机砷

目的建立测定海鱼中无机砷含量的高效液相色谱-电感耦合等离子体质谱法。方法海鱼样品经稀硝酸超声热水浴提取后,AS7阴离子交换色谱柱分离,3.5 mmol/L(NH4)2CO3+1%甲醇与100 mmol/L(NH4)2CO3+1%甲醇流动相梯度洗脱,电感耦合等离子体质谱仪测定,以保留时间定性,外标法定量。结果在1~100μg/L的线性范围,6种砷形态化合物的回归方程均呈良好的线性关系,相关系数均优于0.9996,检出限为0.05~0.25μg/L,定量限为0.17~0.84μg/L,3个浓度加标回收率为88.5%~106.4%,相对标准偏差为2.5%~4.9%。结论本方法满足海鱼中无机砷含量的测定要求,提取快速,稳定,操作简单,检出限低,方法的重现性好,灵敏度高。
