Objective To investigate the interrelations of ALOX5AP SG13S114A/T , COX-2 765G/C , COX-1-50C/T polymorphisms and cerebral infarction. Methods The ALOX5AP SG13S114A/T, COX-2 765G/C and COX-1 50C/T polymorphisms in 411 cases with cerebral infarction and 411 controls were measured by Polymerase Chain Reaction-Restriction Fragment Length Polymorphism method. The generalized multifactor dimensionality reduction (GMDR) method was employed to detect gene-gene interactions. Results Single-gene analysis showed that there were no significant differences in the genotype and allele frequency distributions of ALOX5AP SG13S114A/T, COX-2 765G/C and COX-1 50C/T between two groups. However, in those cases carrying ALOX5AP SG13S114AA as well as COX-2 765CC , the risk of cerebral infarction increased significantly by 2.842 times. Conclusions The combinational analysis among genes used in this study may be helpful in the elucidation of genetic risk factors for common and complex diseases.

Objective To investigate 4 variants single nucleotide polymorphisms (SNPs) of 5-lipoxygenase-activating protein(ALOX5AP) in lipoxygenase pathway and in cytochrome P450 pathway as susceptibility genes for stroke in a southeastern Chinese population,and evaluate the associations between susceptibility genes and cerebral infarction,to find whether gene-gene interactions increase the risk of cerebral infarction.Methods By case-control study,two hundred and ninety-two patients with cerebral infarction and 259 healthy control subjects were included.Eight variants in 5 candidate genes were examined for stroke risk,including the SG13S32 (rs9551963),SG13S42 (rs4769060),SG13S89 (rs4769874),and SG13Sl14 (rs10507391) variants of the ALOX5AP gene,the G860A (rs751141) variant of the soluble epoxide hydrolase (EPHX2) gene,the A1075C (rs1057910) variant of the CYP2C9 *2 gene,the C430T (rs1799853) variant of the CYP2C9* 3 gene,and the A6986G (rs776746) variant of the CYP3A5 gene.Gene-gene interactions were explored using generalized multifactor dimensionality reduction (GMDR)methods.Results There were no statistically significant differences in the frequencies of the genotypes of the 8 candidate genes.The GMDR analysis showed a significant gene-gene interaction between SG13S114 and A6986G,with scores of 10 for cross-validation consistency and 9 for the sign test (P =0.011).These genegene interactions predicted a significantly higher risk of cerebral infarction (adjusted for age,hypertension,and diabetes mellitus;OR =1.804,95% CI 1.180-2.759,P =0.006).Conclusions A two-loci gene interaction confers significantly higher risk for cerebral infarction.The combinational analysis used in this study may be helpful in the elucidation of genetic risk factors for common and complex diseases.

The antisense transcript long non-coding RNA (1ncRNA) (antisense non-coding RNA in the INK4 locus,ANRIL) is an antisense of the cyclin-dependent kinase inhibitor 2B (CDKN2B) gene on chromosome 9p21 that contains an overlapping 299-bp region and shares a bidirectional promoter with alternate open reading frame (ARF).In the context of gene regulation,ANRIL is responsible for directly recruiting polycomb group (PcG) proteins,including polycomb repressive complex-1 (PRC-1) and polycomb repressive complex-2 (PRC-2),to modify the epigenetic chrornatin state and subsequently inhibit gene expression in cis-regulation.On the other hand,previous reports have indicated that ANRIL is capable of binding to a specific site or sequence,including the Alu element,E2F transcription factor 1 (E2F1),and CCCTC-binding factor (CTCF),to achieve trans-regulation functions.In addition to its function in cell proliferation,adhesion and apoptosis,ANRIL is very closely associated with atherosclerosis-related diseases.The different transcripts and the SNPs that are related to atherosclerotic vascular diseases (ASVD-SNPs) are inextricably linked to the development and progression of atherosclerosis.Linear transcripts have been shown to be a risk factor for atherosclerosis,whereas circular transcripts are protective against atherosclerosis.Furthermore,ANRIL also acts as a component of the inflammatory pathway involved in the regulation of inflammation,which is considered to be one of the causes of atherosclerosis.Collectively,ANRIL plays an important role in the formation of atherosclerosis,and the artificial modification of ANRIL transcripts should be considered following the development of this disease.

OBJECTIVETo establish the three-dimensional (3D) visible models of the anatomical structures of the anterior approach to the upper thoracic spine (UTS) for anatomic study and preoperative planning of the UTS.
METHODSSectional images from the superior margin of the first thoracic vertebral body to the inferior margin of the fifth thoracic vertebral body were acquired through the Chinese Visible Human Female (VCHF) database which was collected by the Third Military Medical University. These images were imported into Photoshop CS, cut automatically and converted into a JPEG format. Surface and volume reconstruction were performed by 3D Doctor 3.5 and Amira 4.0 software programs on an ordinary personal computer respectively.
RESULTSThe surface reconstruction model could be rotated at any angle and observed from any direction. And the reconstructed structures of the anterior approach to the UTS could be displayed individually or as a composite with any other selected structure. The volume reconstruction displayed abundant internal details of the reconstructed images in transverse, coronal, sagittal, and random oblique sections.
CONCLUSIONThree-dimensional visible models of the anatomical structures of the anterior approach to the UTS based on the sectional images of VCHF can clearly display the morphology, spatial orientation and adjacent relationship of every structure. These models are very helpful to the anatomy study and preoperative planning of this complex anatomic region.

OBJECTIVEThe combination of oxaliplatin and S-1 is effective in patients with advanced gastric cancer. The purpose of this study was to analyze the safety and compliance of this combination regimen as adjuvant chemotherapy in patients with gastric cancer.
METHODSClinical data of 71 patients with gastric cancer treated with oxaliplatin plus S-1 as adjuvant chemotherapy in the Cancer Hospital, Chinese Academy of Medical Sciences (CAMS) from Jan 1(st), 2010 to Jan 1(st), 2012 were retrospectively reviewed. The types and incidence rate of adverse events related to chemotherapy and the results of follow up of the patients were analyzed.
RESULTSAmong the 71 cases, 17 were treated with oxaliplatin biweekly, while 54 with oxaliplatin triweekly. The most common adverse events were neutropenia (n = 49, 69.0%), nausea/vomiting (n = 51, 71.8%), and anorexia (n = 49, 69.0%). The most frequent grade 3-4 toxicities were neutropenia (n = 13, 18.3%), thrombocytopenia (n = 10, 14.1%), anorexia (n = 5, 7.0%) and nausea/vomiting (n = 4, 5.6%). Seven (87.5%) of the 8 patients previously treated with neoadjuvant chemotherapy experienced thrombocytopenia in the postoperative adjuvant chemotherapy, and four (50%) of the 8 patients experienced grade 3-4 thrombocytopenia. The rates of grade 3-4 adverse events in patients aged 65-years or older were similar to that in younger patients.
CONCLUSIONSThe combination of oxaliplatin and S-1 used as adjuvant chemotherapy is well tolerated by patients with gastric cancer. Neutropenia, thrombocytopenia, nausea/vomiting and anorexia are the major treatment-related adverse events. Patients who received neoadjuvant chemotherapy do not well tolerate this regimen as postoperative adjuvant chemotherapy. This combination regimen has a manageable tolerability profile in adjuvant setting in patients ≥ 65 years old.

OBJECTIVETo evaluate the initial clinical characteristics, the response to treatment, and the outcome in adult patients with Evans syndrome.
METHODSThe clinical data of 84 adult patients (20 males, 64 females) with Evans syndrome diagnosed at our center between 1984 and 2007 were retrospectively analyzed.
RESULTSThe patients were followed up for a median duration of 17.5 (0.03 - 140) months. All the patients initially received intravenous steroids with or without intravenous immunoglobulin (IVIG). Forty-seven patients were treated with corticosteroids alone initially. Complete remission (CR) and partial remission (PR) were achieved in 38 of the patients, but 92.1% of them relapsed during a median follow-up of 12 months. Twenty-eight patients who were resistant to corticosteroids therapy or with severe bleeding were subsequently administered immunosupressive agents. CR and PR were obtained in 89.3% of them. Within a median follow-up of 8 months, 84% of these patients relapsed.
CONCLUSIONSEvans syndrome is a chronic and easy to recurrent disease, which is often refractory to conventional therapy. Treatment with combination agents might be a useful therapeutic approach to the patients.
