??OBJECTIVE To study preliminarily the cadmium absorption and accumulation in Ligusticum Wallichii to provide a scientific basis for solving the problem of cadmium excess. METHODS The aboveground and underground parts of Ligusticum Wallichii in different growth periods and the rhizosphere soil were collected from Aoping Town, Pengzhou City and Yongshou Town, Meishan City. The cadmium content was determined, and the enrichment coefficient and transfer coefficient were calculated. RESULTS The average cadmium content in the underground part was 77.21% higher than that in the aboveground part. The cadmium enrichment coefficients and cadmium transfer coefficients of different parts were both greater than 0.5, and the enrichment coefficient of the underground part was 64.75% higher than the aboveground part. CONCLUSION Ligusticum Wallichii has a certain capacity to absorb and transfer cadmium, and most cadmium is enriched in the medicinal roots.

目的:观察循环应用CAG、IA方案治疗老年初治急性髓性白血病(AML)的疗效及不良反应.方法:25例老年初治AML患者分为CAG、IA循环化疗组(Ⅰ组)以及常规方案化疗组(Ⅱ组),Ⅰ组10例患者给予CAG方案治疗,如达不到完全缓解原方案再次治疗,完全缓解后给予IA方案化疗.间歇1个月后再循环应用CAG、IA方案化疗;Ⅱ组15例患者予常规柔红霉素(DNR)+阿糖胞苷(DA)或米托蒽醌+阿糖胞苷(MA)方案化疗,完全缓解后应用DA、MA、HA和IA等方案化疗.结果:Ⅰ组2个周期完全缓解率为60%(6/10),总有效率达到80%(8/10),而Ⅱ组2个周期的完全缓解率仅为26.7%(4/15),总有效率为53.3%(8/15);Ⅰ组无化疗相关死亡病例,Ⅱ组化疗相关死亡率为20%.结论:循环应用CAG、IA方案治疗老年初治AML患者较传统常规化疗方案治疗具有完全缓解率及2年生存率高,毒副反应小的优点.     

An Electrolytical Method for the Determination of Cations.

The method is based on the solubility in mercury of the amalgams of the cations formed by electrolysis. The amalgams are extracted by rocking movements (Widmark ) AND titrated. The extraction velocity for some cations is determined. Sodium (100 per cent) and potassium (98–99 per cent) are recovered after one hours rocking. After the same time 90 per cent of calcium are extracted, some of the calcium amalgam being precipitated on the glass wall. Ammonium and guanidine are also extracted, but only slowly, magnesium and ferric ion can not be extracted. Direct determinations can be made on serum and erythrocytes, it is important that the proteins are precipitated during the electrolysis. There is good agreement with the values found after ashing of serum; direct determination on the erythrocytes give a somewhat higher value than after ashing. The analyses are carried out with 0.05 ml. serum. The applicability of the method is discussed.     

循证医学在妇产科领域的临床运用

面向新世纪，国际临床医学领域正经历一场巨大变革，特别是我们的医学观念正在发生深刻的变化，其最为重要的特征是：由临床医学结合流行病学、卫生统计学、卫生经济学、互联网和社会学的循证医学观念，正逐渐取代以经验和推论为基础的传统医学观念。在世界范围内，循证医学日渐成为医学教育和医学继续教育的重要组成部分，对不断提高临床医学人才素质、促进临床医学发展发挥着越来越重要的作用。     

Single nucleotide polymorphisms in the D-loop region of mitochondrial DNA and age-at-onset of patients with chronic kidney disease

Background The mitochondrial displacement loop （D-loop） accumulates mutations and single nucleotide polymorphisms （SNPs） at a higher frequency than other regions of mitochondrial DNA （mtDNA）.We previously identified disease riskassociated SNPs in the D-loop of chronic kidney disease （CKD） patients; in this study,we investigated the association of age-at-onset and D-loop SNPs in CKD patients.Methods The D-loop region of mtDNA was sequenced in 119 CKD patients attending the Fourth Hospital of Hebei Medical University between 2002 and 2008.The age-at-onset curve of the CKD patients was calculated using the KaplanMeier method at each SNP site,and compared using the log-rank test.Results The mean age of 119 CKD patients was （55.6±14.2） years,and 56.3% were males.The mean estimated glomerular filtration rate （eGFR） was （81.2±12.4） ml·min^-1·1.73 m^-2,with 79.8% （n=95） of patients having an eGFR 〈60 ml·min^-1·1.73 m^-2.All participants had an eGFR 〉30 ml·min^-1·1.73 m^-2.The age-at-onset for CKD patients who smoked was significantly lower than that of non-smoking CKD patients.The SNP sites of nucleotides 150C/T were identified for their association with age-at-onset using the log-rank test.The age-at-onset of patients with the minor allele T genotype was significantly lower than that of patients with the C genotype at the 150 SNP site （P=0.010）.Conclusions Genetic polymorphisms in the D-loop appear to be predictive markers for age-at-onset in CKD patients.Accordingly,the analysis of genetic polymorphisms in the mitochondrial D-loop may help identify CKD patient subgroups at high risk of early onset disease.
