To analyze the genetic characteristics of echovirus 6 (E6) isolated from meningitis and encephalitis cases in Shandong Province, China, we collected cerebrospinal fluid samples from meningitis and encephalitis cases in Shandong Province from 2007 to 2012 for virus isolation. Viral RNAs were extracted from positive isolates, and complete VP1 coding regions were amplified by RT-PCR and sequenced. Homology comparison and phylogenetic analysis were performed. Six isolates were identified as E6 by microneutralization assay and molecular typing. The homology analysis showed that the six isolates had 78. 6%-99. 8% nucleotide and 95. 5%-100. 0% amino acid identities with each other, as well as 76. 9%-78. 4% nucleotide and 92. 3%-95. 1% amino acid identities with the prototype strain (D' Amori). The phylogenetic analysis based on the integrated VP1 sequences indicated that all Shandong E6 isolates could be separated into four clusters, designated as A, B, C, and D. The six E6 isolates belonged to clusters A, B, and D. Our study reveals high genetic differences between Shandong E6 isolates and suggests different transmission lineages of E6 co-circulated in Shandong Province.

To provide theoretical basis for breeding good variety of Dendrobium denneanum, agronomic and qualitative characters of 4 different lines and relationships among them were studied. The stem length, stem diameter, leaf length, leaf width, length/ width ratio and leaf area were measured. The single fresh and dry stem was weighed and drying rate was calculated. The contents of polysaccharides and total alkaloids were determined by sulfuric acid-phenol colorimetry and acid-dye colorimetry, respectively. The correlations between characters were analyzed. The results showed that differences in major agronomic characters between four lines were significant. The plant types of dq-1 and dq-2 were higher, dq-3 was medium and dq-4 was lower. The fresh weigh of stem and content of polysaccharides were the highest in dq-2, 7.81 g and 14.33%. While the highest content of total alkaloids and was 0. 486% in dq-3. There were significant correlations between agronomic characters, but these characters had low or non correlations with qualitative characters such as polysaccharides and total alkaloids. It was shown that the content of polysaccharides and total alkaloids were significantly different among 4 lines of D. denneanum, which could be selected for different uses.

OBJECTIVETo evaluate the relation of dose intensity and efficacy, toxicity in advanced breast cancer treated with paclitaxel as a single agent.

METHODSSeventy-one patients with advanced breast cancer received paclitaxel as a single agent with different dose intensities. According to the phase I or phase II trial, the standard dose intensity of paclitaxel was defined as 58.3 mg.(m(2))(-1).week(-1). The dose of paclitaxel was 175 mg/m(2) given every three weeks, ranging 33.3 - 70.3 mg.(m(2))(-1).week(-1) [median delivered dose intensity 58.82 mg.(m(2))(-1).week(-1)]. Efficacy and toxicity was evaluated.

RESULTSThe overall response rate in this group of advanced breast cancer was 40.8%. Responses were seen in lungs, soft tissue, bone and liver, with the response rates of 52.0%, 38.0%, 12.5%, 7.7%, respectively. When the relative dose intensity (RDI) was > 1.0, 0.9 - 1.0, < 0.9, the response rates were 44.2%, 47.6%, 0, respectively. The difference between the group (RDI >/= 0.9% - 1.0%) in 7 patients and the group (RDI < 0.9) was significant (P < 0.05). Toxicity was well tolerated, with the efficacy decreased as soon as the RDI had been reduced without embarrassing the toxicity.

CONCLUSIONPaclitaxel as a single agent therapy with standard dose intensity is effective and well tolerated by patients with advanced breast cancer.

Objective To analyze the evolution and genetic characterization of echovirus 11 (Echo11 ) from the acute flaccid paralysis (AFP) cases in Shandong province. Methods Isolation of Enterovirus was performed from stool samples of AFP cases from 1994 to 2009. All positive strains were sero-typed by neutralization test. Entire VP1 coding region from 27 strains typed as Echo 11 was amplified by reverse transcription-polymerase chain reaction(RT-PCR), and subsequently phylogenetic analyse on VP1 sequences from these strains and others published in GenBank were conducted. Results From 1994 to 2009, altogether 915 non-polio enterovirus (NPEV) strains were isolated with 79(8.6% ) isolates serotyped as Echo11. There were 876 nucleotides (nt) in the complete VP1 genes, encoding 292 amino acids (aa). The nt identities were 76.4%-100.0% among those Echo11 Shandong strains with the aa identities as 91.4% -100.0%. The nt and aa identities were 77.7%-80.7% and 90.7%-94.8% between Shandong strains and prototype strains, respectively.Conclusion All Echo11 strains could be divided into four genotypes. Shandong strains that forming three (A1, A2 and C1) new sub-genotypes, with every sub-genotype had several brands.Sub-genotype A1 appeared to be the lately circulating one.

BACKGROUNDMany patients with acute coronary syndrome (ACS) develop recurrent angina (RA) during hospitalization. The aim of this non-randomized, prospective study was to investigate the predictive factors of RA in unselected patients with ACS enrolled in the global registry acute coronary events (GRACE) during hospitalization in China.

METHODSBetween March 2001 and October 2004, enrolled were 1433 patients with ACS, including ST segment elevation myocardial infarction (662, 46.2%), non-ST segment elevation myocardial infarction (239, 16.7%) and unstable angina (532, 37.1%). The demographic distribution, medical history and clinical data were collected to investigate the predictive factors of RA by Logistic regression.

RESULTSDuring hospitalization 275 (19.2%) patients were documented with RA including unstable angina (53.2%), non-ST segment elevation myocardial infarction (27.5%), ST segment elevation myocardial infarction (19.3%). A comorbidity of dyslipidemia, prior angina, percutaneous coronary intervention (PCI) within 6 months was more common in patients with RA, P < 0.05. In the patients with RA, a significantly higher proportion of patients with acute pulmonary edema was observed, 23 (8.4%) versus 43 (3.7%), P = 0.001. Acute renal failure was present in 8 (2.9%) of patients with RA versus 19 (1.6%) of patients without RA, P = 0.165. Hemorrhagic events were present in 6 (2.2%) of patients with RA versus 8 (0.7%) of patients without RA, ventricular tachycardia/ventricular fibrillation events in 12 patients (4.3%) versus 22 patients (1.9%), congestive heart failure in 69 patients (25.0%) versus 94 patients (8.1%), myocardial re-infarction in 28 patients (10.1%) versus 15 patients (1.3%), P < 0.05, respectively. A lower proportion of patients with RA underwent in-hospital PCI, 687 (59.3%) versus 114 (41.5%), P = 0.000. A higher proportion of patients with RA received heparin, 260 (94.5%) versus 1035 (89.4%), P = 0.006; and beta-blockers 176 (64.0%) versus 864 (74.5%), P = 0.000. Multivarible regression analysis showed that RA was associated with prior angina (OR 2.086, 95% CI 1.466 - 2.967), in-hospital PCI (OR 0.579, 95% CI 0.431 - 0.778), in-hospital congestive heart failure (OR 2.410, 95% CI 1.634 - 3.555), myocardial re-infarction (OR 7.695, 95% CI 3.701 - 15.999), beta-blocker (OR 0.626, 95% CI 0.458 - 0.855), and heparin (OR 3.411, 95% CI 1.604 - 7.382).

CONCLUSIONSIn-hospital congestive heart failure, myocardial re-infarction, prior angina history and use of heparin are stronger independent predictors of RA; beta-blockers and PCI are also important predictive factors for RA.

OBJECTIVETo identify the pathogen caused an outbreak of aseptic meningitis in Tancheng county of Shandong province in 2008, and to analyze the molecular characterization of VP1 gene of the Coxsackievirus B3(CVB3) isolates.

METHODSStool and cerebrospinal fluid(CSF) specimens were collected from this outbreak for virus isolation with RD and Hep-2 cell. After typing by neutralization test, the VP1 gene of the isolates were amplified by RT-PCR and sequenced. Homologous comparison and phylogenetic analysis were performed.

RESULTS35 strains of enteviruse were isolated from 22 stools and 120 CSFs(7 from stools and 28 from CSFs), 34 strains identified as CVB3 and 1 as Echovirus 30(ECHO30) by neutralization test. The nucleotide homologies were 90.5%-100.0% in the partial VP1 gene (381 bp) among 34 CVB3 isolates. Homology comparisons indicated that Shandong strains have the identity of 79.5%-81.6% with the CVB3 prototype strain Nancy. 012/2008TC/SD/CHN and 177/2008TC/SD/CHN showed the highest nucleotides homologies (98.2% and 91.0% respectively) with Fuyang19 strain of Anhui province in 2008 in complete VP1 gene. The phylogenetic tree based on complete VP1 genes showed that all the CVB3 correlated with aseptic meningitis in China recently came from the same evolution linkage and formed a monophyletic cluster.

CONCLUSIONThe causative agent of this outbreak of aseptic meningitis was CVB3. CVB3 circulated in China was genetically different from other countries.
