This study provides the candidate sequences in the identification of Radix et Rhizoma Clematidis and its adulterants using DNA barcoding. We amplified and sequenced the region psbA-trnH, with the data of 284 sequences from GenBank, the differential intra- and inter-specific divergences, genetic distance, barcoding gap were used to evaluate five barcodes, and the identification efficiency was assessed using BLAST1 and Nearest Distance methods. The results showed that psbA-trnH barcodes performed high identification efficiency and inter-specific divergences among the five different DNA barcodes. Analysis of the barcoding gap and NJ tree showed psbA-trnH was superior to other barcodes. Based on the identification and PCR amplification efficiency, psbA-trnH can be the ideal barcode to identify Radix et Rhizoma Clematidis and its adulterants accurately.

To establish a new method for identifying genus of Lilium by DNA barcoding technology, ITS, ITS2, psbA-trnH, matK and rbcL sequences were analyzed in term of variation of inter- and intra-species, barcoding gap, neighbor-joining tree to distinguish genus of Lilium based on 978 sequences from experimental and GenBank database, and identification efficiency was evaluated by Nearest distance and BLAST1 methods. The results showed that DNA barcoding could identify different species in genus of Lilium. ITS sequence performed higher identification efficiency, and had significant difference between intra- and inter-species. And NJ tree could also divide species into different clades. Results indicate that DNA barcoding can identify genus of Lilium accurately. ITS sequence can be the optimal barcode to identify species of Lilium.

OBJECTIVETo evaluate the effects of prenatal stress on neurological functions after middle cerebral artery occlusion (MCAO) in adult offspring rats.

METHODSPregnant rats were randomly assigned to prenatal stress treatment, which was exposed to restraint three times daily in the last week of pregnancy, and no prenatal stress treatment. Adult male offspring rats were subjected to transient focal cerebral ischemia by MCAO. They were randomly divided into four groups: sham group, prenatal stress + sham group, MCAO group and prenatal stress + MCAO group (n = 10). After 24 hours of reperfusion, the neurological deficits were evaluated. The infarct size, cell apoptosis and expression of Caspase 3, cleaved Caspase 3 and Bcl-2 were detected.

RESULTSCompared with MCAO group, the neurological deficits, infarct size and apoptotic cells in prenatal stress + MCAO group were increased significantly (all P < 0.05). The expressions of Caspase 3 and cleaved Caspase 3 were much greater in prenatal stress + MCAO group than those of MCAO group, while the expression of Bcl-2 was significantly decreased in prenatal stress + MCAO group compared with MCAO group (all P < 0.05).

CONCLUSIONPrenatal stress might exacerbate neuroloeical deficits in the offspring rats after MCAO by increasing cell apoptosis.

0.05).Conclusions IL-4/C-589T gene polymorphism is present in children in Wenzhou City.IL-4/-589T may be important candidate gene for RSV bronchiolitis.

Objective To discover radioresistance-associated proteins by performing comparative proteomic analysis on nasopharyngeal carcinoma cell lines.Methods The total proteins were extracted from radioresistant human nasopharyngeal carcinoma cell line CNE-2R and its parental cell line CNE-2,respectively.These proteins were separated by high quality two-dimensional polyacrylamide gel electrophoresis (2-DE) and then the 2-DE profiles were screened for differentially expressed protein spots by the Image Master 5.0 software.Those spots were identified by a matrix-assisted laser desorption/ionization time-of-flight tandem mass spectrometry.Results 32 significantly differentially expressed protein spots were screened in two different radiosensitivity cell lines and 11 proteins were identified by tandem mass spectrometry,among which 3 proteins were up-regulated in radioresistant human nasopharyngcal carcinoma cell line CNE-2R and the other 8 proteins were down-regulated.Conclusions The differentially expressed proteins of nasopharyegeal carcinoma cells with different radiosensitivity were mainly involved in apoptosis regulation,DNA damage and repair,cell cycle regulation,RNA transcription,cell signaling,cytoskeleton formation and radiation stress responses.

Objective To evaluate the follow-up results of patients with cervical intraepithelial neoplasia Ⅲ(CIN Ⅲ)after surgical treatment.Methods A retrospective analysis of consecutive patients with CIN Ⅲ after surgical treatment between Jan 1st,1999 and Jun 30 th,2004 was performed.The follow- ups of the patients after surgical treatment were assessed.Results In the follow-up of patients with CINⅢ after surgical treatment,the rate of abnormal cytology was 9.3%.The rate of follow-up was higher in patients with cervical conization than in patients with initial hysterectomy and in patients of the oncological group than of the non-oncological group.The rate of follow-up was lower in patients over 40 years old.There was no difference in the residential areas of the patients.Conclusions Cytological follow-up of patients with CINⅢ after operation is varied.The rate of follow-up is lower in patients over 40 years old,in patients having initial hysterectomy and in patients of the non-oncological group.The rate of follow-up is associated with the knowledge about CIN of both surgeons and patients.

0.05).Among the 26 pregnancies,there occurred one ectopic pregnancy and four cases of spontaneous abortion.In the 13 delivery cases,there were one premature delivery,two cases of premature rupture of the membrane,and ten cases of cesarean section.The sample height of the cone was less than 2.0 cm in the nine delivery cases,and the mean width of the cone was over 2.5 cm.Conclusion No evidence of secondary infertility caused by cervical conization was found.There was also no significant increase in the number of either premature delivery cases or low birth weight infants. The sample height of the cone might play a more important role in the pregnancy outcome than the width, which still needs to be further verified by larger studies.

Trachoma, a contagious keratoconjunctivitis ( KC ) , caused by Chlamydia trachomatis infection, is rife in 57 countries in the world at present. The World Health Organization ( WHO) listed the global alliance to eliminate blinding trachoma by 2020 as one of top priorities of its blindness prevention in 1998. A simplified classification system for identifying and naming trachoma, designated by WHO, and the SAFE strategy based on community intervention were extended continuously in the world in 10 years since then. The trachoma prevalence trend has showed a change compared with that in the past. China has launched the blindness prevention action, aimed to eliminate blinding trachoma by 2016. In this paper, we reviews progress in diagnosis, treatment and epidemic of trachoma since the extension of the SAFE strategy.

Objective To investigate perception of high performance work system (HPWS) and work engagement for hospital employees in Hangzhou,take work climate for concerning employees as a meditating factor to analyze how HPWS influences work engagement by setting structural equation model.Methods Using cluster random sampling to select 983 hospital employees for questionnaire survey,data was analyzed by statistical description,one-way ANOVA and SEM.Results Hospital employees' average work engagement score was 21.62 ± 4.37.Both HPWS and work climate for concerning employees had overall effects on work engagement for 0.63 and 0.44 respectively.Meanwhile,HPWS made a direct effect for 0.24 and indirect effect for 0.39 mediated by work climate for concerning employees.Conclusion Work engagement for hospital employees could be further enhanced and carrying out HPWS and work climate for concerning employees shall help hospital employees feel the organization put great importance on them and work even harder in return.
