Gene Expression Omnibus (GEO)can act as an international public resource platform storing and sharing experimental data generated from high-throughout research projects that utilize genome-wide expression strategies like microarray screening and analysis.Numerous data involving inflammatory carcinoma models is helpful for dissecting the regulatory network and molecular mechanism of oncogenesis,thus offering favorable clues for new thoughts in prevention and treatment of cancers.GEO originated from various disease models or processed experiments also provides researchers with powerful evidence for tracing functions of novel predictive genes.

Fibulin protein family has widely existed in the extracellular matrix, and plays an important role in maintain the stable of basement membrane, elastic fibers and loose connective tissue. Fibulin-5 (FBLN-5) is one of the members of the Fibulin protein family, which is essential to the structure function and cell mediated action. The lack of FBLN-5 will cause many diseases such as internal organ deformity. Current research suggests that changes of expression level of FBLN-5 are associated with the occurrence of tumors such as lung cancer, and also can influence the tumor proliferation, invasion and prognosis, thus may become a new molecular marker for cancer diagnosis. Therefore, in this review, we summarize and update biological characteristics and functions of FBLN-5, and its role in the development of tumor formation mechanism.

Paroxysmalnocturnalhemoglobinuria(PNH)isadefectdiseaseofacquiredclonal hematopoietic stem cel s. It can be expressed as hemolytic anemia, hemoglobinuria, and venous thrombosis. Cerebral venous sinus thrombosis (CVST) is a rare but serious complication of PNH. Here we report a PNH patient with CVST and reviewthe relevant literature. For patients who have the risk factors for CVST and neurological symptoms, such as headache and increased intracranial pressure, should early conduct brain imaging examination and make the diagnosis clear, and give an active treatment in the aspects of anticoagulation, dehydration, eliminating the causes of disease, and controling complications.

Objective To compare the curative effect and biomechanical performance of cannulated compression screw (CCS) and dynamic hip screw-blade (DHS-B) in the treatment of patients with femoral neck fracture.Methods Between February 2010 and February 2014,102 patients with femoral neck fracture were treated with CCS or DHS-B at our department.They were 54 males and 48 females,aged from 15 to 86 years.There were 30 subcapital fractures,51 transcervical ones and 21 base ones.CCS was used in 60 patients and DHS-B in 42.In-hospital data were collected retrospectively to compare the curative effects in 2 groups.Furthermore,femoral neck fracture models were established using 12 adult cadaveric femoral specimens.The 12 models were randomized into 2 equal groups (n =6).Group A was subjected to fixation by 3 CCSs and group B to fixation by DHS-B.The 2 groups were compared in terms of axial loading test,rotation test and destructive axial loading test.Results The operation time (59.4 ± 20.2 min),incision size (4.1 ±0.6 cm) and intraoperative blood loss (25.9 ±9.9 mL) in the CCS group were significantly less than those in the DHS-B group (88.6±22.9 min,12.1 ±1.2cmand 156.7±107.1 mL) (P ＜0.05).The Harris hip score for the DHS-B group (91.9±9.8) was significantly higher than that for the CCS group (87.2 ± 9.2) (P ＜ 0.05).There were no significant differences between the 2 groups in hospital stay,partial weight-bearing time,or postoperative complications (P ＞ 0.05).At 500 N vertical loading,the stress values at both medial and lateral sides of the femur in group A were significantly smaller than those in group B (P ＜ 0.05).There were no significant differences between groups A and B in the average sinking displacement of femoral head or the torque at a torsion angle of 6° (P ＞ 0.05).The maximum load in group A (2,135 ±120 N) was significantly smaller than that in group B (2,986 ± 98 N) (P ＜ 0.05).Conclusion In treatment of femoral neck fracture,DHS-B fixation is obviously superior to CCS fixation,because the former is in better agreement with the femoral biomechanical property,and performs better in anti-rotation and anti-compression,leading to better functional recovery of the affected hip.

Objective To explore the ideal treatment mode of brain metastases by Meta-analysis.Methods Articles were searched for from the databases at home and abroad using English and Chinese keywords.Searching time limited from the databases setting up to December 30,2012.Jadad score was applied to evaluate the qualities of literatures.RevMan5.0 software was applied to perform the Meta-analysis.A totle of 25 articles including 2 750 patients were eligible for the Meta-analysis,which divided into groups with different treatment.Results Compared with monotherapy,combined therapy improved 1-year survival (OR =0.58,95％ CI:0.46 ～0.71,P ＜0.000 01).In combined therapy groups,compared with two methods,three kinds of therapies improved 1-year survival (OR =0.63,95 ％ CI:0.50 ～ 0.80,P =0.000 1).Compared with local therapy only or systemic therapy only,systemic combined local therapy improved 1-year survival (OR =0.68,95％ CI:0.53 ～ 0.86,P =0.001 ; OR =0.59,95％ CI:0.41 ～ 0.86,P =0.006).In systemic combined local therapy groups,three kinds of treatments improved 1-year survival compared with two methods (OR =0.52,95％ CI:0.35 ～ 0.78,P =0.002).Compared with non-molecular targeted therapy,molecular targeted therapy improved 1-year survival (OR =0.76,95％ CI:0.67 ～ 0.87,P ＜ 0.000 1).Conclusion The reasonable treatment for patients with brain metastases is combined treatment with operation,radiotherapy and chemotherapy.There is better curative effect added molecular targeted therapy based on original scheme,if patients have targeted therapy indications.

Objective To study the effects of Weibimei and its Chinese medicine portions(cortex frangulae, fennel powder, acorus tatarinowii, glycyrrhizae and asparagus) on cell cycle regulation in gastric cancer cells and growth inhibition in gastric cancer Xenografts.Methods Gastric cancer SGC-7901 cells were normally cultured and treated with Weibimei, extractum glycyrrhizae, cortex frangulae, fennel powder, acorus tatarinowii and asparagus.Then, the proliferation of SGC-7901 cells were detected by MTT assay, their effect on SGC-7901 cell cycle were measured by flow cytometry, and the expression of cell cycle related proteins were examined by Western blot.Animal models of SGC-7901 cells xenografts in nude mice were constructed to evaluate the growth inhibition effects of Weibimei and its Chinese medicine portions, and the expression of STAT3,p-STAT3, Cyclin D1, Bcl-2 and Survivin in gastric tumors were detected by immunohistochemical assays.Results Weibimei and its three kinds of Chinese medicine portions, cortex frangulae, fennel and acorus tatarinowii could obviously inhibit the proliferation of SGC-7901 cells, compared to control group, with a statistical significant difference (P<0.05).The cell cycle of SGC-7901 was arrested at G1 phase with cortex frangulae, fennel and acorus tatarinowii treatment, the expression of Cyclin A, B, D, E were decreased significantly (P<0.05).However, no significant effects was found in glycyrrhizae or asparagus group.Xenografts tumor sizes in Weibimei, cortex frangulae, fennel or acorus tatarinowi groups were much smaller than that in saline group or Triple Therapy group (three-kinds-drugs-combination for the treatment of gastric ulcer) (P<0.05).Xenografts experiments showed that the tumor growth in nude mice in Weibimei, cortex frangulae, fennel or acorus tatarinowi groups were significantly smaller than that in control group or in Triple Therapy Group (P<0.05), and phosphorylated STAT3, and STAT3 signaling targeted genes, including Bcl-2, Cyclin D1 and Survivin were all significantly down-regulated by immunostaining.Conclusion Weibimei and its Chinese medicine portions including cortex frangulae, fennel and acorus tatarinowii can could significantly inhibit the growth of SGC-7901 cells proliferation and arrested the cell cycle of G1 phase in vitro, and inhibit gastric cancer xenografts in nude mice in vivo.

Objective To investigate the feasibility of buccal mucosa swab method to isolate genomic DNA for au-tism spectrum disorders (ASD)-related genetic screening. Methods Buccal mucosa swabs and blood were collected from 41 children with ASD. Genomic DNA was extracted from either blood by using a commercial genomic DNA kit or buccal mucosa swab by using phenol-chloroform-isoamyl alcohol method. The concentration, total quality and purity of genomic DNA were compared between these two methods. Genotyping of the ASD-related methylenetetra-hydrofolate reductase (MTHFR) gene C677T locus was analyzed using PCR-restriction enzymatic digestion and sanger sequencing was per-formed for validation. Results The total quality [(5.87±2.58)μg vs. (2.00±0.92)μg] and concentration [(143.25±72.78) mg/L vs. (66.68±24.43) mg/L] of genomic DNA extracted from buccal mucosa swab were higher than that form blood (P<0.05), while the purity was not significantly different between these two methods (P>0.05). Genotyping analysis of MTHFR was also consistent between these two methods. Conclusion Buccal mucosa swab is a simple, non-invasive and reliable meth-od to obtain genomic DNA, which can partially replace blood for analysis of ASD-related gene polymorphisms.

Objective To investigate the predictive value of plasma copeptin level for the outcomes in patients with acute ischemic stroke. Methods Consecutive patients with acute ischemic stroke were enroled in the study. Enzyme-linked immunosorbent assay was used to detect the plasma copeptin level. The National Institutes of Health Stroke Scale (NIHSS) was used to evaluate baseline stroke severity. The outcome was evaluated at 90 days with the modified Rankin Scale (mRS), and the good outcome was defined as mRS 0 - 2. Results A total of 160 patients with acute ischemic stroke were enroled, 121 had good outcome and 39 had poor outcome. The age (71. 87 ± 6. 11 years vs. 66. 19 ± 9. 39 years; t =- 3. 540, P = 0. 001), serum levels of C-reactive protein (6. 84 ± 2. 80 mmol/L vs. 5. 84 ± 2. 89 mmol/L;t = - 2. 459, P = 0. 023) and copeptin (143. 12 ± 34. 02 pmol/L vs. 50. 78 ± 18. 62 pmol/L; t = 21. 564, P <0. 001), NIHSS score (12. 00 ± 4. 00 vs. 6. 00 ± 3. 00; t = - 7. 861, P < 0. 001), as wel as proportions of patients with hypertension (79. 5% vs. 60. 3% ; χ2 = 4. 758, P = 0. 029), atrial fibrilation (20. 51% vs. 7. 44% ; χ2 = 4. 022, P = 0. 045), and large artery atherosclerotic stroke (43. 59% vs. 22. 31% ; χ2 = 6. 696, P = 0. 010) in the poor outcome group were significantly higher than those in the good outcome group, but diastolic blood pressure was significantly lower (89 ± 12 mmHg vs. 95 ± 9 mmHg, 1 mmHg = 0. 133 kPa;t = 3. 323, P = 0. 001). Multivariate logistic regression analysis showed that the plasma copeptin level (odds ratio 2. 332, 95% confidence interval 1. 725 - 3. 153; P < 0. 001) was an independent risk factor for the poor outcome in patients with acute ischemic stroke. Person correlation analysis showed that the plasma copeptin level and baseline NIHSS score showed a significant positive correlation (r = 0. 895, P < 0. 001). Receiver operating characteristic (ROC) analysis showed that plasma copeptin level has a significant predictive value for the poor outcome at day 90 after acute ischemic stroke (area under the ROC curve = 0. 740, 95%confidence interval 0. 623 - 0. 783; P < 0. 01). When plasma copeptin level > 104. 3 pmol/L was used as the cutoff value, the sensitivity and specificity for predicting the poor outcomes at day 90 after onset were 86. 8% and 40. 2% , respectively. Conclusions The plasma copeptin level may be a good predictor for neurological outcome at day 90 after onset in patients with acute ischemic stroke.
