Objective To evaluate the feasibility of detecting the mutation of IDH1 in glioma patients by high resolution melting(HRM) curve analysis.Methods The gene mutation of IDH1 was detected by HRM method in 9 surgical resection paraffin specimens of glioma,and the result was verified by gene sequencing.Results 6 cases of R132H(CGT ＞ CAT) mutation and 1 case of R132C(CGT ＞ TGT) mutation were found by HRM method.The resluts of direct gene sequencing were consistent with HRM method.Conclusion The HRM method in detecting IDH1 mutation is more efficient and convenient than direct sequencing.Moreover,it has advantages of low-cost and suitable for clinical test.

0.05). There was only 2/109 cases (5.8%) need a second course of antibiotics because of likely infection and 102/109 cases (93.5%)need not any moor antibiotics. The mean period of antibiotic treatment in group Ⅰ, group Ⅱa and group Ⅱb were (1.2?0.5) days,(4.8?0.8) days and (9.3?1.8) days,respectively.There were significant differences(all P

Objective To investigate the effect of individual nostalgia therapy on positive feelings and sadness of the spouses of postoperative patients with esophageal cancer. Method From June 2014 to June 2015, 60 hospitalized patients and their 60 spouses were set as control group. Routine health education and guidance were conducted once or two times a week for 7 weeks. Another 60 cases of hospitalized patients and their 60 spouses during July 2015 and June 2016 were set up as observation group. The patients were treated with the same nursing intervention as in the control group, and their spouses were subjected to individual nostalgia treatment once a week for 7 weeks. Before the intervention (postoperative day 2) and 7 weeks after the intervention, the positive aspects of caregiving (PAC) and the Margit-Meuser caregiver grief ineventary short form (MM-CGI-SF) were used to investigate their positive feelings and sadness. Result The score on spouse's positive feelings in the observation group after intervention was significantly higher than those of the control group and that of the observation before intervention (P < 0.01). Conclusion Individual nostalgia can effectively improve the feelings of the spouses of esophageal cancer patients and reduce their grief.

OBJECTIVE To investigates the effects of imperatorin on the oxidative stress in the cerebral cortex and hippocampus after focal cerebral ischemia/reperfusion injury. METHODS Transient focal cerebral ischemia/reperfusion model in male Sprague-Dawley rats was induced by 2 h middle cerebral artery occlusion followed by 24 h reperfusion. Imperatorin (1.25 and 2.5 mg·kg- 1) or vehicle were administered intraperitoneally at 1, 5 and 9 h after the onset of ischemia. At 24 h after reperfusion, the biomarkers of oxidative stress such as the levels of reactive oxygen species (ROS), lipid peroxidation products malondialdehyde (MDA), nitric oxide (NO) and total antioxidant capacity (T-AOC), the activities of inducible nitric oxide synthase (iNOS), superoxide dismutase (SOD) and catalase (CAT) in the cerebral cortex and hippocampus were observed. We also assessed the nuclear factor erythroid 2-related factor 2 (Nrf2), heme oxygenase-1 (HO-1), and the NAD(P)H-quinone oxidoreductase 1 (NQO-1) protein expression by Western blot. RESULTS As compared to vehicle-treated animals, imperatorin treatment significantly reduced the ROS, MDA, NO levels and iNOS activity, increased T-AOC and the activities of SOD and CAT. Furthermore, imperatorin treatment also significantly induced the nuclear translocation of Nrf2, enhanced the protein expression of HO-1 and NQO-1 in the cerebral cortex and hippocampus. CONCLUSION Our findings indicate that imperatorin can protect the brain against the excessive oxidative stress induced by cerebral ischemia/reperfusion through activation of Nrf2 signaling pathway.

OBJECTIVETo introduce the framework of evidence-based practice with a case of castration-resistant prostate cancer (CRPC) as an example.

METHODSA clinical question was formulated according the clinical scenario. A systematic search was conducted for the published literature in the databases of PubMed, EMBASE, Cochrane Library, Clinical Trial Registries, and Web of Knowledge up to Dec 2014. The identified literature was reviewed for quality appraisal before the evidence was applied to clinical practice.

RESULTSThe treatment was effective and the patient achieved disease remission.

CONCLUSIONEvidence-based practice should be integrated with clinical scenario, current evidence, and patients' willingness, and follow a systematic framework.

Objective To observe the effect of propofol on cognitive functions and hippocampus tissue in hyperlipidemia aged rats.Methods Seventy-six aged male SD rats were selected and randomly divided into basal diet with propofol injection (group PI), basal diet with normal saline injection(group N1), high-fat diet with propofol injection (group P2) and high-fat diet with normal saline injection (group P2), with 19 rats in each group.Eight weeks later,group P1 and P2 received intraperitoneal injection of propofol 100 mg · kg-1 · d-1 for 5 days.While in group N1 and N2, rats received the same intraperitoneal injection of equal volume normal saline.One day after the last injection, escape latency and space exploration were detected by Morris water maze in the next six days.One hour after the last water maze test, the serum and hippocampus were sampled to detect the expression of beta-amyloid protein and receptor for advanced glycation endproducts(RAGE) by immunohistochemical method and ELISA respectively.Results In place navigation tests,the escape incubation period(98.20±25.40)s in group P1 was obviously longer than that in N 1 group (47.50± 11.08) s (P＜ 0.01).Compared with P2 (99.79 ± 20.38) s, escape incubation period was shortened in N2 (50.70± 20.55) s (P＜ 0.05).There was no significantly difference between N2 and N1 (P＞0.05), while the escape incubation period in group P2 was longer than P1 (P＜ 0.05).In spatial probe test,platform passing number ((2.86 ±1.46)times) in group P1 were less than that in N1 group ((7.50± 1.70) times, P＜0.05).In group N2, the platform passing number ((6.60 ±3.91) times) were more than those in group P2 ((1.16 ±1.16)times, P＜0.05) while there was no significant difference between group N1 and N2 (P＞0.05).Times of crossing platform in group P2 were less than that in P1 group (P＜0.05).Compared with group N1((147.83±60.88) ng/L) and N2((152.73±87.50) ng/L) ,the expression of RAGE protein was increased in group P1((629.89±110.33) ng/L) and P2((229.89±53.20) ng/L) (P＜0.05).There was no significant difference between N1 and N2 groups(P＞0.05) ,while the expression of RAGE protein in P1 group was lower than that of P2(P＜0.05).In immunohistochemical test, positive expression cells in P1 ((18.49± 1.53) and P2 (25.67±3.08)) were higher than that in group N1(9.33±2.31) and group N2(12.14±2.52) (P＜0.05) ,while there was no significant difference between group N1 and N2(P＞0.05).Conclusions Anesthetic dose of propofol can injure spatial learning and memory ability in aged rats.Hyperlipidemia might act synergistically with propofol.

Objective To study the relation between alcohol-induced osteonecrosis of femoral head (AIONFH) related with high morbidity TCM constitution type with CYP2C8 gene polymorphisms.Methods Totally 152 Han nationality NONFH cases from Feburary 2014 to September 2015 from outpatient and the inpatient departments in Gansu Province Hospital of TCM were collected. 50 AIONFH cases were set as medical case group; meanwhile, 45 healthy volunteers were enrolled as control group. Database for medical materials of all patients and volunteers was established. TCM distribution for AIONFH patients was determined. Solution DNA extraction kit was used to extract DNA, and detect the concentration and purity of DNA. The target gene was amplified by PCR and the target gene was amplified by gel electrophoresis. The length of the fragment was confirmed to conduct target gene sequencing.
