Transrectal ultrasonography is one of the early diagnostic approaches of prostate cancer.In this article,the recent study progression of conventional transrectal ultrasonography with combination of new techniques,such as contrast-enhanced ultrasonography,elastography,image fusion,and so on,in diagnosis of prostate cancer was summarized on the basis of a review of the literatures.

Objective To analyze the constitutes of essential oil form Nervilia fordii. Methods GC-MS was used to analyze the essential oil. The relative content of each component was determined by area normalization. Results Fifty-five kinds of constitutes were identified,accounting 97.1 %of total contents. The content of 2-Pentadecanone,6,10,14-trimethyl is the highest,being 13.55 %,which had also been found in the same family. Conclusion 2-Pentadecanone,6,10,14-trimethyl can be used for the identification of the same family.

Optic neuritis is one of the most important neuro-ophthalmologic diseases which cause vision loss in young adults. There are obvious differences in the prevalence of optic neuritis in different countries and regions. Through the review of the related literature at home and abroad in recent years, this article summarizes the etiology and epidemiological characteristics of optic neuritis. lt is expected to provide reference and comparison for the epidemiological investigation of cross regional, multi-center cooperation.

Sixty-three morphological traits from 743 specimens of the 41 taxa within the cultivated Lonicera japonica were observed and measured, such as the height of plants, the length of leaf, the width of leaf, the length of anther, the alabastrum's number of one branch, the color of alabastrum and so on. A numerical taxonomy is presented by using the cluster analysis, principal components analysis (PCA) and factor analysis. Sixteen of 63 characters were screened by means of PCA and used for cluster analysis of 41 taxa with the method of Ward linkage and average euclidean distance. The cluster analysis showed that the 41 taxa could be divided into 5 groups when the Euclidean distance coefficient was 11.84. The factor analysis indicated that the shape of leaf, color of alabastrum, the pilosity and color of twiggery were of significance for the cultivated L. japonica classification. The results of this study will be a base for the core collection and breeding of L. japonica.

We collected 22 cultivated population of Lonicera japonica from 17 areas. The characteristics of non-glandular hairs were observed and measured by the scanning electron microscopy. The principal components analysis and correlation analysis were conduct based on length and density of L. japonica. The results showed a significant negative correlation between length and density of non-glandular hairs, and the characteristics of non-glandular was not corrrelated significantly with latitude. The correlation results indicated that the density was a key to separate "Damaohua" and "Jizhuahua". The contribution of climate and soil was important to the cultivated population. This reminded that the characteristics of non-glandular hairs were affected by environmental and genetic interaction.

Status epilepticus(SE)is one of the most common medical emergencies in children.There has been some recent understanding of this fife-threatening condition with reference to the definition,forms of ignorable seizure,drug treatment and role of EEG monitoring.This review discusses the current information regarding the definition,diagnosis,treatment of status epilepticus and the latest advance on management of refractory SE in children.

Objective To investigate the association between genetic polymorphisms of exon3 of nicotinic acetylcholine receptor ?4 subunit (CHRNA4) and sporadic Alzheimer's disease(SAD).Methods In 23 SAD patients and 30 people of normal control, exon3 of CHRNA4 was screened by PCR-DGGE and DNA sequencing.Results Three new genetic polymorphisms were found in the exon3 of CHRNA4: C104T, A136G, G169A.The frequnces of these three genes in SAD group were 35%,46%,61% respectively and in control group were 13%,13%,33% respectively. There were significant difference between two groups (all P

Objective To investigate the association between apolipoprotein J(ApoJ)gene polymorphism and type 2 diabetes mellitus(T2DM).Methods The exons 3、4、7、8 of ApoJ gene were screened by polymerase chain reaction-denaturing gradient gel electrophoresis(PCR-DGGE)in 61 type 2 DM patients and 60 healthy control subjects of Chinese population.Abnormal bands were sequenced.Results The deletion/insertion polymorphism site in exon 7 of the ApoJ gene on two subject groups had significant difference (P0.05).Conclusion ApoJ of exon 7 deletion/insertion polymorphism is one of the genetic marker of 2 DM and the ApoJ polymorphism may be associated with 2 DM.
