Objective To evaluate the clinical results of Willis covered stent implantation and coil embolization in the treatment of cranial internal carotid artery (CICA) aneurysm. Methods Eighty-nine patients with CICA aneurysms were selected for treatment with Willis covered stents (n = 43, group A) or coil embolization (n =46, group B) according to the patients'will. Data on the technical success, initial procedure time and in-hospital interval, initial and final angiographic results, mortality, morbidity, and final clinical outcomes were collected and analyzed for the two groups at 6 months post-procedure. Results Endovascular covered stent placement and coil embolization were technically successful in all patients,except for one patient in group A. The initial angiographic results showed complete occlusion in 34 patients of group A (81%, 95% CI: 69%, 93% ) and 24 patients of group B (52%, 95% CI: 37%, 67% ) ( P ＜0. 05). The final angiographic results indicated complete occlusion in 39 patients of group A (39/41,95%,95% CI: 88%, 102% ) and 22 patients of group B (22/45,49%, 95% CI: 34%, 64% ,P ＜0. 01 ). The average procedure time was(103 ± 13)min in group A and (143 + 39) min in group B (P＜0. 01). No significant differences were seen between the two groups in technique success, mortality, morbidity, or final clinical outcomes. Conclusion In this nonrandomized, prospective trial, CICA aneurysm treatment with covered stents yielded midterm angiographic results that were superior to those of coil embolization.

BACKGROUNDTo evaluate the influence of assays with primer labeled with fluorochrome (Cy5) and dUTP labeled with Cy5 on the signal intensity of the chip for detection of hepatitis B virus (HBV) gene polymorphism.

METHODSThe P-region and pre-C/C-region of HBV gene were amplified by polymerase chain reaction (PCR) with Cy5 labeled primer or Cy5 labeled dUTP. The amplicons of the two assays were hybridized with chips, scanned and analyzed by computer software for the detection of HBV gene polymorphism.

RESULTSThe signal intensity of assay with Cy5 labeled dUTP was slightly higher than that of assay with Cy5 labeled primer, but non?specific signal intensity of the assay with Cy5 labeled dUTP was higher. The result of 42 samples showed that there was no significant difference between the two assays, and that both had a good repeatability and CV value (15%-20%).

CONCLUSIONSThe assay with Cy5 labeled primer may replace the assay with Cy5 labeled dUTP as a routine method to detect HBV gene polymorphism, and it is simpler and cheaper.

Objective: To investigate the value of platelet count in predicting the efficacy of rituximab treatment in chronic primary immune thrombocytopenia (ITP). Methods: A retrospective study was conducted in 103 chronic ITP patients hospitalized in our medical center between January 2011 and December 2014. The sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV) of platelet count in different time points were analyzed for the predictor of treatment response. Optimal cutoff values were established using ROC analysis. Results: A total of 103 patients were included in the study. There were 46 males and 57 females, with a median age of 30 (18-67) years. At day 1, 3 and 7 after the first dose of rituximab, there was no significant difference in platelet counts between the success group (PLT≥50×10⁹/L after treatment) and the failure group (PLT≤50×10⁹/L after treatment) (P>0.05). At day 14 after rituximab treatment (PTD 14), platelet counts became significantly different in the success and failure groups[41(8-384)×10⁹/L vs 23(0-106)×10⁹/L, P=0.003], and remained different thereafter, with increasing significance in the subsequent follow-ups. Patients were divided further using an optimal cut-off platelet count of 50×10⁹/L on PTD 14, PTD 30, and PTD 60, and PPV and NPV values were calculated for predicting eventual success and failure. Conclusion Response can be predicted by obtaining platelet counts at 14, 30 and 60 days after rituximab treatment. The study proposed a protocol that guides patient monitoring and management planning.

ObjectiveTo explore the effect of Ganoderma leucocontextum ethanol extract (GLE) on silicosis and its potential molecular mechanism using network pharmacology, molecular docking technology and animal experiments. Methods i) The components of GLE were analyzed using ultra-performance liquid chromatography-Q Exactive-mass spectrometry (UPLC-QE-MS) method. The active components, potential molecular pathways and targets of GLE in the intervention of inflammation process of silicosis was explored using network pharmacology and molecular docking technology. ii) Specific pathogen free male C57BL6/J mice were divided into four groups with 10 mice in each group. The mice in the silicosis model group and GLE intervention group were given a dose of 80 μL silica suspension with a mass concentration of 50 g/L once by non-exposed tracheal instillation, and the mice in the blank control group and GLE control group were given an equal volume of sterile 0.9% sodium chloride solution. From the second day after modeling, GLE control group and GLE intervention group were given GLE at a dose of 200 mg/(kg•d) by gavage, while blank control group and silicosis model group were given the same volume of 0.9% sodium chloride solution by gavage, once per day for 35 days. After that, the histopathological changes of lung tissues of mice were observed, the lung mass coefficient, inflammation score and the ratio of collagen deposition area were calculated, and the levels of tumor necrosis factor (TNF) -α, interleukin (IL) -1β and IL-6 in the lung tissues of mice were detected by enzyme-linked immunosorbent assay. Results i) A total of 76 active components of GLE were detected by UPLC-QE-MS. Among them, 36 ingredients met the screening criteria of the five principles of drug-like components. A total of 67 potential targets of the 36 GLE active ingredients to improve the inflammatory response of silicosis were screened based on the network pharmacology theory. The result of Kyoto Encyclopedia of Genes and Genomes enrichment analysis and Gene Ontology functional analysis showed that IL signaling and cytokine signaling of immune cells played a key role in the process of anti-silicosis of GLE. The results of molecular docking showed that the top 10 targets based on the 67 intersection targets were TNF, IL6, B-cell lymphoma 2, cellular tumor antigen p53, Caspase-3 subunit p12, JUN, epidermal growth factor receptor, IL1B, 67 kDa matrix metalloproteinase-9 and prostaglandin G/H synthase 2. The result of protein-protein interaction analysis showed that glycyrrhetinic acid had the strongest affinity with the key targets TNF-α, IL-1β and IL-6, followed by ganoderma acid DM, alismatol C, ganoderma acid β and red sapogenin. ii) The results of histopathological examination showed that the inflammatory response and collagen deposition were alleviated in the lungs of mice with silicosis. The lung mass coefficient, inflammation score, ratio of collagen deposition area and IL-6 expression in lung were lower in mice of the GLE intervention group (all P<0.05), compared with the silicosis model group. However, there was no significant difference in the levels of TNF-α and IL-1β in lung tissues between the two groups (all P>0.05). Conclusion GLE may reduce silica-induced lung inflammation and fibrosis by inhibiting the IL-6 level in lung tissues of mice. Its mechanism is associated with the synergistic action of multi-components, multi-targets and multi-pathways.
