This paper was aimed to study the genetic diversity and genetic relationship of germplasm resource of Lonicerae Japonicae Flos in order to provide references for its breeding. A total of 36 samples from 18 farm varieties and wild species, as well as related species of Lonicera japonica Thunb. from the main production areas were studied by ISSR-PCR markers. The Jaccard coefficient was worked out by NTSYS-pc software. And a cluster dendrogram of different samples was established based on unweighted pair-group method with arithmetic mean (UPGMA). The re-sults showed that 12 ISSR primers generated 129 loci of which 114 loci were polymorphic. The average percentage of polymorphic bands (PPB) is 88.37%. In the cluster dendrogram, different samples of Lonicera japonica are in the same group, which showed that it is a natural species; the wild sample is separated from the cultivated samples; the traditional type-Maohua is relative stable, but the type of Jizhuahua includes complicated varieties, and it has obvi-ous genetic variation; the new variety Jiufeng 1 has already distinct into one stable type. It was concluded that the ISSR method was suitable for germplasm identification, genetic diversity analysis of Lonicerae Japonicae Flos, thus providing a theoretical foundation for its cultivation and breeding.

Objective To investigate the effect factors for language and memory dominance testing in propofol Wada test in refractory epilepsy patients.Methods From January 2010 to August 2013,total of 23 patients underwent propofol Wada tests for language and memory dominance evaluation.According the performance in language test and memory test,the patients were divided into two groups,respectively:succeed with test or failed in test.The relevant factors including age,duration of epilepsy,handedness,FIQ (full scale of intelligence quotient),lateralization of lesions,language dominance,dose of propofol and the adverse effects of propofol were recorded as independent variables.Logistic regression was adopted to screen the effect factors for memory dominance evaluation.All statistical analyses were processed with SPSS software.Results All 23 patients succeeded with language test,but only 13 patients succeed with memory test.The difference of success ratios between language test and memory test was significant (P=0.001).For memory test,the difference of duration of epilepsy and FIQ in success group and failed group was significantly different (duration of epilepsy:(10.57±4.68) vs (18.30±9.30),P=0.032,FIQ:(81 ±25.33) vs (64.2±10.86),P=0.046).More grade Ⅱ adverse effects of propofol occured in the patients who failed in memory test (P=0.011).Logistic regression results indicated the grade Ⅱ adverse effects of propofol were the main risk factor for memory test failure (OR=28.0,P＜0.01).Conclusions Propofol Wada test is an effective method for language dominance evaluation.However,the effect factors for memory dominance evaluation are much more than language evaluation,such as duration of epilepsy,FIQ and grade Ⅱ adverse effects of propofol,and grade Ⅱ adverse effects of propofol may be the most significant risk factor.

Dwindling supplies of conventional energy sources and the demand to increase the share of renewable energy for sustainability have increased the significance of biogas, the product of synergistic fermentation of biodegrable organic wastes from municipal, agricultural and industrial activities by microbial populations under anaerobic conditions. With extensive research and engineering practice, many technologies and modes have been developed for biogas production and application. Currently, the most widely used mode is the complete-mixing mesophilic fermentation. Europe, especially Germany, is leading the world in the combined heat and power production (CHP) from biogas. In this paper, updated progress in biogas technologies is reviewed, with focuses on anaerobic microorganisms, bioreactor configurations and process development, biogas production and applications, in which perspectives of biogas as a clean and renewable energy are projected.

Objective To identify the genetic mechanism of fetuses with short limbs deformity.Methods From Aug.2008 to Aug.2011,ten fetuses with obvious short limbs were found in ultrasound screening performed at 18-24 and (or) 30-32 gestational weeks and underwent artificial induced labor with the patient' consent.Amniotic fluid or cord blood of the fetuses was collected for karyotyping analysis and detection of mutation point of fibroblast growth factor receptor 3 (FGFR3)gene by polymerase chain reaction and gene sequencing.One fetus (case 3) who presented with achondrogenesis underwent sequencing of SLC26A2 and Trip11 gene meanwhile.Results Among the 10 fetuses with short limbs deformity,five cases were found during second trimester and five during third trimester.Nine cases were identified as normal karyotype and one was chimera (46,XY/45,XY,- 18).One fetus carried a rare FGFR3 mutation of c.1108G＞T (G370C) and was diagnosed as thanatophoric dysplasia at 21+3 weeks.Three fetus carried c.1138G＞A (G380R) mutation and were diagnosed as achondroplasia.These four families had low recurrent risk because no gene mutations were found in the parents.Three mothers of these four fetuses were pregnant again and had normal neonates now.No mutations were found in all gene sequencing in case 3.Conclusions Karyotyping analysis and sequencing of FGFR3 gene could find causative gene mutations and provide genetic counselling and prenatal diagnosis for some fetuses with short limbs deformity.In the third trimester,achondroplasia is the most possible diagnosis when short limbs fetus is found by ultrasound.

Objective To investigate the chemical properties of superficial cardiac neurons. Methods By means of immunohistochemical ABC technique,the study was performed concerning the distribution of calcitonin gene-related peptide(CGRP) and substance P(SP) in the canine main cardiac superficial plexus. Results CGRP-immunoreactive(IR) neurons were found in every plexus,but SP-IR neurons could be observed only in dorsal atria plexus(DAP),inter atria plexus(IAP) and aorta-pulmonary plexus(A-PP).The shape and size of CGRP-IR and SP-IR neurons were similar.The comparative study on atria and ventricles indicated that CGRP-IR and SP-IR neurons in atria were more than those in ventricles.Numerous CGRP-IR,SP-IR nerve fibers could be observed in each fat pats and intermyocardiocytes.These nerve fibers were usually situated near blood vessels,or were attached to vessel wall.Somewhat CGRP-IR and SP-IR nerve fibers were connected with myocardiocytes in some regions.Conclusion The results indicated that actually existed two peptides in canine cardiac superficial plexus.These implied that the regulations of the two kinds of peptidergic neurons to atria and ventricle were different.The two kinds of neurons mentioned above were likely to perform different or similar functions in canine heart.CGRP and SP could possibly modulate the activities of myocardiocytes and vessels of heart directly.

OBJECTIVETo explore the differences between the Bayesian interim analysis and the classical interim analysis.

METHODSTo compare the means of two independent samples between control and treatment, superior hypothesis test was established. In line with the data requirements for group sequential design, Type Iota error of Bayesian interim analysis based on various prior distributions, Power, Average Sample Size and Average Stage were estimated in the interim analysis.

RESULTSIn the Pocock and O' Brien & Fleming designs, the Type Iota errors in the Bayesian interim analysis based on the skeptical prior distribution and the handicap prior distribution were controlled at around 0.05. When the powers of these two classical designs were both 80%, Bayesian powers of the skeptical prior distribution and the handicap prior distribution were markedly lower. The powers of the non-informative prior distribution and the enthusiastic prior distribution were distinctly higher than 80%.

CONCLUSIONIn the Bayesian interim analysis based on the skeptical prior distribution and the handicap Prior distribution, the Type Iota errors can be well controlled. Bayesian interim analyses using these two prior distributions, compared with the analysis adopting the O' Brien & Fleming method, can markedly increase the possibility of ending the clinical trials ahead of time. The Bayesian interim analyses based on these two distributions do not have practical value for group sequential design of the Pocock method.
