Edema, as one of common clinical diseases, could be treated by taking medicines and adopting external therapies with traditional Chinese medicines (TCM). In recent years, there have been many clinical and basic studies concerning external therapies with TCM on edema Data showed that the external therapies are mostly composed of such purgating drugs as Rhei Radix et Rhizoma, Natrii Sulfas and Pharbitidis Semen, heat-clearing drug such as Phellodendri Chinensis Cortex and resuscitation-inducing drug such as Borneolum Syntheticum. The study showed that ingredients of external therapies did not pass through hilum and hepatic system, and thus avoided the first pass effect of livers. They enabled effective components of drugs to be rapidly absorbed through pores and skins, strengthened the effect against edema, shortened the treatment course, decreased side effects, and were convenient and inexpensive. External therapies with TCM could play unique advantages in inhibiting edema in the future clinical studies.

Recent studies indicated that epigenetic abnormality is the important molecular mechanism in leukemia. The change of epigenetic modification occurs in most kinds of leukaemia. Based on the epigenetic modification, the therapies of leukemia with hypomethylating agents and histone deaeetylases inhibitors, which are different from traditional chemotherapy are applied in the treatment of leukemia at beginning. The aim of this article is to summarize the recent advances of DNA methylation and histone modification in leukaemia occurrence, treatment and prognosis.

Objective To assessed the distribution of two single nucleotide polymorphism (SNP)loci (rs2383206.rs10757278)on chromosome 9p21 in Xinjiang Uygur and Han nationality populations,and to investigate correlation and the incidence of all cases of macrovascular disease (coronary artery disease,carotid atherosclerosis and peripheral arterial disease)and analysis of risk factors.To further study the correlation between the incidence of two single nucleotide polymorphism (SNP)loci (rs2383206.rs10757278)on chromosome 9p21 in type 2 diabetes melli-tus(T2DM)of Han and Uygur ethnic and the incidence of all cases vascular disease,then to analysis the risk factors. Methods 497 adults with T2DM who were treated in the Endocrinology department in hospital from May 2012 to April 2014 were involved in this study,including 298 Uygur patients and 199 Han patients.215 non -T2DMpatients who were treated in the Cardiology department in hospital were also involved in the study,including 93 Uighur patients and 122 Han patients.Then the total 712 patients were detectedby using PCR -SNP Stream technology to analyse rs2383206.rs10757278 loci SNP genotyping.The relevant results were compared with t test,two different genotype distribution and allele frequency were compared with χ2 test,multiple factors analysis were calculated by Logisitic regression.Results The distribution of genotype with two SNP loci had no significant difference between the patients in Uygur group and Han group (rs2383206χ2 =5.570,P =0.062;rs10757278 χ2 =2.721,P =0.257 ),and there's no significant difference between the patients with macrovascular disease and non -macrovascular disease in all patients(rs2383206χ2 =0.120,P =0.950;rs10757278 χ2 =1.027,P =0.598).Logisitic regression analysis showed that the incidence of macrovascular was significantly associated with increasing age(χ2 =28.820,P =0.000)and fatty liver(χ2 =5.210,P =0.020)in Uighur group with type 2 DM.In Han group with type 2 DM,the macrovascular was significantly associated with the increase of age (χ2 =19.980,P =0.000),elevated fasting blood glucose (FPG)(χ2 =4.070,P =0.044)and poor controlled with glycosylated hemoglobin (χ2 =4.280,P =0.040). Conclusion This study found that there's no correlation between two single nucleotide polymorphisms (SNPS)loci (rs2383206.rs10757278)on chromosome 9 p21 large with macrovascular in Uygur group and Han group.Increasing age,higher FPG and poor controlled with glycosylated hemoglobin combined with fatty liver were the risk factors for macrovascular.

Objective To investigate the echocardiographic features in patients with right atrial myxoma and thus evaluate the value of echocardiog?raphy in the diagnosis of right atrial myxoma. Methods The echocardiographic findings of 20 patients with right atrial myxomas were retrospectively analyzed,and the echocardiographic features of these patients were summarized. Results The main clinical symptoms of right atrial myxoma includ?ed chest tightness,shortness of breath,lower limb edema,and syncope. Of these 20 patients,the echocardiography showed that the average size of the right atrial myxomas was 3.11 cm × 2.90 cm to 7.44 cm × 4.52 cm. The myxomas were round or oval shape in 15 patients(75%)and lobulated shape in 5(25%). The myxomas were attached to the atrial septum in 15 patients(75%)and to right atrial free wall in 25%of the patients. The aver?age width of the basement was 1.62±0.30 cm,and the width was greater than 1 cm in 80%of the patients had the width over 1 cm. Some myxomas had internal areas of calcification and anechoic cystic areas. The percentages of patients with the blocking of right atrium,tricuspid and pulmonary hy?pertension were 70%,50%,and 10%,respectively. Conclusion The echocardiographic features of right atrial myxoma were specific. Echocardiog?raphy can accurately assess the tumor and identify the secondary changes in cardiac structure and hemodynamics and thus provide evidence for time?ly and accurate diagnosis of right atrial myxoma.
