20 mm has negative correlation with restenosis.

0.05).Conclusion Aspirin plus cilostazol showed comparable antithrombotic effect as aspirin plus ticlopidine after elective coronary stenting and may serve as an alternative treatment for patients intolerable to ticlopidine.

Abstract: Objective　The main aim of the study is to sequence the complete genome of two Getah virus strains (GS11-155 and HNDZ1712-1) isolated in Gansu Province and Hainan Province in 2011 and 2017 respectively and analyze the molecular and genetic evolution of the two strains compared with M1, which was first isolated in 1964 in Hainan Province, China. Methods　Genome of two newly isolated Getah viruses were sequenced by virus gene amplification technique, and the genomic database of Getah viruses was established. The molecular characteristics and genetic evolution of the viruses were analyzed by bioinformatics software. Results　The genome length of two new isolated Getah virus strains (GS11-155 and HNDZ1712-1) was 11 690 nt and 11 621 nt, respectively. Both strains had the structural characteristics of Alphavirus genome. Although the nucleotide sequence lengths of structural genes, non-structural genes and non-coding junction regions of the two strains were identical, the nucleotide sequence lengths of the 5' and 3' non-coding regions of the viral genomes were a few different. The 3'UTR repeats elements in the genomes of the two virus strains did not change. It was 97.7% and 98.1% different of nucleotide and amino acid homology between both strains of Getah virus, HNDZ1712-1 isolated in 2017 and M1 isolated in 1964 in Hainan Province. Interesting, Gansu 2011 cluster and Hainan 2017 cluster were emerged leading by both strains GS11-155 and HNDZ1712-1 respectively, those two clusters totally independent with M1 virus isolated from Hainan in 1964 in whole genome phylogenetic analysis first. Conclusions　Although the HNDZ1712-1 was also isolated from mosquito samples in Hainan Province, it was in a completely different evolutionary branch from the M1 isolated from Hainan Island in 1964, and was closely related to the strain isolated from Gansu Province (GS11-155) thousands of kilometers away. It is suggested that the two new strains of Getah virus are different from the Getah virus isolated in 1964.

OBJECTIVETo investigate the relationship between Arg778Leu/Gln gene mutation spot in ATP7B and TCM Syndrome type in Chinese patients with Wilson disease (WD).

METHODSExon 8 of ATP7B of 90 WD patients and 30 healthy controls were amplified by PCR and analysed by restriction enzyme Msp I, the TCM Syndrome type of the patients was differentiated at the same time.

RESULTSIn the 90 WD patients, 34 with Arg778Leu/Gln of exon 8 were detected, among them 20 cases belonged to the TCM Syndrome type of endogenous Liver-Wind agitation.

CONCLUSIONOnset age of WD patients with Arg778Leu/Gln mutation is later than that without this mutation. Arg778Leu/Gln mutation might be related to the TCM Syndrome type of endogenous Liver-Wind agitation.

OBJECTIVE To improve capability of nosocomial infection(NI) prevention and control in reusable textiles management.METHODS In an investigation to previous reused textiles handled procedure,care to keep from creation of potential infectious aerosols should not be taken in contaminated textiles collection,transportation of clean and soiled textile was done in undistinguished uncovered vehicles,sorting room shared a common space with dressing room and washing room,and personal protection was not performed in handling contaminated textiles.RESULTS A series of NI management as follows effectively were adopted in hospital laundry.Appropriate bags were adopted for collecting used textiles or fabrics at the point of generation and subsequently closed securely for transportation of them to the laundry.An independent sorting area with exclusive ventilation system was separated from other parts of the laundry.Hand hygiene facilities and products and appropriate personal protective equipments were available.Transportation and storage of clean from soiled textiles were separated.CONCLUSIONS Appropriate handling and processing textiles in infectious disease hospital plays key role in NI management.

Objective To investigate the dynamic changes of the spinal cord during neck flexion in Hirayama disease for diagnosis.Methods MRI examinations in neutral neck position and a fully flexed neck position were performed on 18 cases of Hirayama disease and 31 young normal control subjects.We measured an antero-posterior diameter(APD)and transverse diameter(TD)of the cervical cord at the superior margin of the C6 vertebral body for each position,and investigate the dynamic changes.The different in frequency of these findings between the control and patient groups was examined by means of the x~2 test.The group means were compared by independent-sample t-test.Significance was defined as P

A canine distemper virus strain was isolated from the lung of dog coming from Aksu in Xing Jiang using lung primary M cell during the CDV molecular epidemiological study. It was demonstrated to be a virulent strain of CDV by a series of systematic identification such as morphology , serology neutralization test, canine infection test, and molecular virology test.

Objective To analyze the clinical features and two HLA-DQB1alleles in their associa-tions with vitiligo.Methods Clinical data of243patients with vitiligo were collected and the HLA-DQB1al-leles were determined by a PCR-SSP assay in both patients and control groups.Results The mean age of the first onset was23.1years for the males,and23.7years for the females.The localized type was the major form in the initial stage.The segmental type mainly occurred in childhood.Age of the first onset was younger in pa-tients with familial history than those in patients without familial history.HLA-DQB1*0201allele was associ-ated with non-segmental type only.Conclusions①The pathogenesis might be different between non-segmen-tal and segmental vitiligo.②Polygenic inheritance may explain vitiligo with familial history.There might be a difference of genetic background between vitiligo with or without familial history.③HLA-DQB1*0201allele may be the susceptible gene or have close linkage with susceptible gene in vitiligo vulgaris.

OBJECTIVE To investigate the correlation between nasal obstruction score, Lund-Mackay score,congestion index and tissue remodeling degree of nasal mucosa in patients with chronic rhinosinusitis(CRS) and to study the role of diagnosing remodeling.METHODS Forty-three patients with CRS who underwent endoscopic surgery were studied.Congestion index of nasal mucosa was obtained by acoustic rhinometry.Nasal obstruction score was obtained by visual analogue scale.CT score was obtained by Lund-Mackay.The mucosa specimen of uncinate process from nasal cavity of the patients was used to evaluate the fibrosis degree.Statistical analysis was performed using SPSS11.5.RESULTS Nasal obstruction and Lund-Mackay score had no correlation with fibrosis degree of mucosa(r=0.77,P=0.40),whereas congestion index of nasal mucosa had a negative correlation with fibrosis degree of mucosa(r=-0.348, P=0.022).CONCLUSION Nasal congestion index can reflect the degree of remodeling in submucosal tissue.Nasal congestion index with obstruction symptoms and CT scan can be used to guide the CRS treatment strategies.
