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.

Gastric cancer is one of the most common malignancies and is the third leading cause of cancer-related deaths worldwide, constituting a serious threat to human health. Long non-coding RNA (lncRNA) is involved in the occurrence and development of gastric cancer at multiple levels and plays critical regulatory roles. It plays important roles in the diagnosis, treatment and prognostic assessment of gastric cancer. This review focuses on the recent research advances in the clinical applications of lncRNA in gastric cancer.

Objective To investigate the application of modified early warning score ( MEWS) to the nursing care of the patients in Emergency Observation Room, and to explore the relationship between outcome and prognosis. Methods According to the convenience sampling method, 331 patients in Emergency Observation Room from a grade A tertiary hospital were assessed by MEWS. The observation factors included the relationship between MEWS at the first day of entering the room and patients′ observation time, MEWS after three days and prognosis. Results Patients′ MEWS at the first day had no correlation with observation time or prognosis ( r=0.052,0.097;P>0.05); patients′ MEWS after three days was related to prognosis(r =0.550, P<0.05). Moreover, the higher MEWS implied the worse conditions and higher mortality. Conclusions MEWS can imply patients′illness outcome and prognosis in order to help nurses to make nursing decision.

Objective To explore the effect of quality control circle activity on pressure ulcer management in critically ill patients.Methods Quality management tools were applied to analysis the causes of hospital pressure ulcer event in critically ill patients of emergency room and medical intensive care unit (MICU) along with improving those tools.And then,effects were compared before and after improvement.Results The incidence of pressure ulcer was 3.6% before improvement and 1 .0% after improvement in emergency room;the incidence of pressure ulcer was 7.8% before improvement and 3.6% after improvement in MICU;there were statistical significance in all of them (χ2 =7.1 38,8.253;P <0.01 ).Conclusions Quality control circle activity effectively decreased the incidence of pressure ulcer in critically ill patients by adding the tool for skin decompression,standardizing the process of pressure sore assessment,strengthening the cooperation between doctor and nurse,organizing nurses training and playing coordination and guidance functions of functional departments.

Objective To study the clinical effect of electric toothbrush on oral care among patients with orotreacheal intubation. Methods A total of 100 cases of orotracheal intubation were randomly divided into two groups, 50 cases in observation group and 50 cases in control group. The patients of observation group used electric toothbrush with chlorhexidine for oral care, and the patients of control group received the traditional oral care method. Results The oral cavity cleanness (80% ofⅠdegree) in the observation group were significantly better than 24% Ⅰdegree cleanness patients of the control group, while the Ⅱ and Ⅲ degree were 16% and 4% of the observation group were lower than 46% and 30% of the control group (χ2 =26. 606, 10. 519, 11. 977;P<0. 01). The 3rd day of bacteria culture obtained 28% of negative rate lower than that of 56% in the control group (χ2 =8. 046;P<0. 01). The patients of observation group utilized (9. 78 ± 1. 16) min/time compared with (8. 91 ± 0. 96) min/time (t=4. 121,P<0. 01). There was no statistical significance on the difference of adverse event rate between two groups (P>0. 05). Conclusions The clinical effect of oral care using electric toothbrush with chlorhexidine compared with patients with orotracheal intubation, the former one is better than the traditional oral care method.

Small intestinal bacterial overgrowth (SIBO) is characterized by changes in the number or species of small intestinal flora. Patients with liver cirrhosis often have intestinal congestion, edema, and delayed peristalsis and develop SIBO, which can further aggravate intestinal abnormalities. In patients with liver cirrhosis, SIBO can lead to significant adverse clinical outcomes, and since the increase in intestinal permeability may cause bacterial translocation into systemic circulation, SIBO is considered an important risk factor in the pathogenesis of liver cirrhosis, spontaneous bacterial peritonitis, and hepatic encephalopathy. Antibiotics, especially rifaximin, are the most effective therapies for SIBO, and in addition, studies are being conducted to investigate the efficacy of potential therapies such as prokinetic agents, probiotics, non-selective β-receptor blocker, and liver transplantation.

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.
