Objective To study the genetic diversity of different geographical populations of Houttuynia cordata in China.Methods The genetic diversity of 15 geographical populations of H.cordata from 13 provinces in China was estimated using amplified fragment length polymorphism(AFLP) markers.The data of amplified bands were analyzed by the software POPGENE and MEGA.Results The ten AFLP primers employed produced a total of 110 discernable and reproduceable amplified fragments.The percentage of polymorphic bands within different populations was 70.51%.Genetic diversity analysis showed that effective number of alleles(Ne) was 1.210,Nei′s gene diversity(H) was 0.119,and Shannon′s genetic diversity index(I) was 0.186.The coefficient of genetic distance was 0.008 9—0.181 8 among populations.A UPGMA dendrogram based on Nei′s(1972) genetic distance visualized that the 15 populations were grouped into three different clusters,Emei population was one individual cluster group and the other populations were grouped into two different clusters corresponding to the different geographical areas.Conclusion The genetic diversity within different geographical populations of H.cordata in China is plentiful.

Objective To investigate the effect of epinephrine combined with methoxamedrine on rate of successful cardiopulmonary resuscitation (CPR) in rabbit model of sudden cardiac arrest by the method of clamping the trachea to asphyxia.Methods Twenty-seven rabbits were randomly (random number)divided into methoxamedrine group,epinephrine group and epinephrine combined with methoxamedrine group.After the modeling,rabbits in the three groups were treated methoxamedrine,epinephrine,and epinephrine combined with methoxamedrine respectively by intravenous injection during CPR.The change of heart rate (HR),mean arterial pressure (MAP) and electrocardiogram (ECG),restoration of spontaneous circulation (ROSC) and mortality within 2 hours of each experimental group were recorded before suffocation and 15 min,30 min,60 min,120 min after the success of the resuscitation.The pathological changes of myocardium were observed under optical and electronic microscope.Results The number of ROSC rabbits in methoxamedrine group,epinephrine group and epinephrine combined with methoxamedrine group were 1,6,5 respectively.The heart rate and mean arterial pressure of the rabbits after ROSC were lowered compared with those before suffocation significantly (P ＜0.05).The levels of mean arterial pressure at 15 minutes and 30 minutes after ROSC in combined treatment group were higher than those of epinephrine group significantly (P ＜ 0.05).The myocardial structure of rabbits after ROSC observed by optical and electronic microscope showed an acute injury,however,the damage degree of myocardium in combined treatment group was slighter.Conclusions Epinephrine combined with methoxamedrine has no apparently additional effect on ROSC during CPR compare with epinephrine used alone,but this combination of two agents can be benefit for stabilizing hemodynamic at early post-ROSC stage,and methoxamedrine can reduce the damage of myocardium during CPR.

ObjectiveTo investigate the association of single nucleotide polymorphisms (SNPs)of rs11833579 and rs12425791 on chromosome 12pl3 with cerebral infarction in the Fujian Han population.MethodsA case-control association study containing a total of 216 cases and 279 controls was carried out.The genotypes of two polymorphisms were evaluated by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) and direct DNA sequencing followed by association analysis.Results The frequency of G ＞ A genotype of rs12425791 in patients with cerebral infarction was lower than that in the controls (34. 3％ vs 43.4％ , x2 = 4. 298 ,P ＜ 0. 05 ) after stratified by causes of cerebral infarction, there was no significant difference in this genotype between large-artery atherosclerosis and controls.Association analysis was performed by logistic regression model after adjusting by sex, age, hypertension, diabetes mellitus, dyslipidemia, smoking and drinking. Rs12425791 G ＞ A genotype was significantly associated with both cerebral infarction ( OR = 0. 627, 95％ CI 0. 417-0. 941, P = 0. 024 ) and large-artery atherosclerosis ( OR =0. 613, 95％ CI 0. 396-0. 949 ,P =0. 028). G ＞ A genotype might be a potential protective factor in male( OR =0. 597, 95％ CI 0. 364-0. 978, P =0. 041 ). rs11833579 G ＞ A genotype frequency was similar between cases and controls.Conclusion rs12425791 G ＞ A on chromosome 12p13 might be a genetic marker for atherothrombotic brain infarction in Han population of Fujian.
