BACKGROUND:Bronchial asthma is considered general y to have an association with Th2 immune response disease, but there is no ideal treatment. Bone marrow mesenchymal stem cel s as a kind of adult stem cel s not only have the multipotent differentiation and proliferation capacity, but also have low immunogenicity and immunoregulation ability. OBJECTIVE:To investigate the effect of culture supernatant of bone marrow mesenchymal stem cel s on lung inflammation of bronchial asthma mice. METHODS:Twenty experimental mice were randomly divided into control and experimental groups, 10 mice in each group. At 0 and 14 days, intraperitoneal injection of ovalbumin induced sensitization in mice, and at 24-26 days, aerosolized ovalbumin solution was used for excitation. From the 24th day, in the experimental group, bone marrow mesenchymal stem cel supernatant was intraperitoneal y injected at 2 hours before excitation;meanwhile, normal saline was injected in the control group. At the last of excitation, the mice were sacrificed under anesthesia to take serum samples, bronchoalveolar lavage fluid and lung tissues. RESULTS AND CONCLUSION:(1) Mice in the control group appeared to have abnormal lung tissue structure, and there were a large amount of eosinophils and monocytes in the submucosa and muscularis. However, lung inflammation was relieved in the experimental group after bone marrow mesenchymal stem cel treatment. (2) The levels of interleukin-17 in the bronchoalveolar lavage fluid and serum were significantly lower in the experimental group than the control group (P<0.05), but there was no difference in the levels of interleukin-4 between the two groups (P>0.05). These findings indicate that the intraperitoneal injection of bone marrow mesenchymal stem cel s can ease lung inflammation and reduce levels of inflammatory markers in the bronchoalveolar lavage fluid and serum of bronchial asthma mice.

Objective To mine the relation between leukemia and genes using Weka. Methods The papers on leuke-mia and genes were retrieved from PubMed, their subject headings and subheadings were extracted using BICOMB to generate co-occurrence matrix and term-paper matrix. The research hotspots were found by cluster analysis of the data on co-occurrence matrix using Weka and Cobweb. The literature was verified. Results The 42 high fre-quency words were clustered into 7 classes by Weka. No high frequency words of leukemia or genes were found in classes 1, 2, 4 and 5, indicating that their clustering efficiency was poor. The clustering efficiency of the other 3 classes was good. Conclusion Cluster analysis showed that leukemia is related with myc gene, ab1 gene, p53 gene, virus gene, immunoglobulin gene and mdm gene.

Objective To explore the correlation of urine albumin and creatinine ratio(UACR)and short -term prognosis in patients with acute ischemic stroke (AIS).Methods 112 patients with AIS were selected as the research subjects.The admission UACR and related laboratory examination indexes were detected,the US national institutes of health stroke scale (NIHSS)scores,and 28 d after admission of the modified Rankin scale (mRS) prognostic score were recorded.The NIHSS 5 or more points and NIHSS <5 points,different levels and UACR patient observation index between the different prognosis group were compared.Results NIHSS 5 or more group of patients on admission UACR level[(15.41 ±3.21 mg/g)]was higher than the NIHSS <5 patients (9.52 ±2.04)mg/g (t =12.214,P <0.001);UACR acuity 11.60mg/g group in NIHSS of 5 or more proportion of patients (87.5%),mRS score >2 points (82.1%),the proportion of the recent death patients (23.2%)than the proportion of UACR <11.60mg/g,the proportion of the group (32.1%,25.0%,7.1%;the chi -square values 33.509,34.476,5.598,all P <0.050);MRS score >2 groups of patients UACR level[(16.10 ±3.29)mg/g]was higher than that in patients with mRS score 2 points or less (8.38 ±1.95)mg/g(t =20.132,P <0.001);Pearson correlation analysis showed that the standard of UACR and NIHSS score (r =0.412,P <0.05 ),high -sensitivity C -reactive protein (hs -CRP)(r =0.473,P <0.050),white blood cell count (WBC)(r =0.442,P <0.050),fasting plasma glucose (FPG)(r =0.375,P <0.050)were positively correlated.Multiariable Logistic regression analysis showed that UACR (OR =1.587,P <0.050)was a recent independent risk factors of poor prognosis in patients with AIS. Conclusion UACR the illness severity and recent prognosis of patients with AIS is closely related to high levels of UACR may be recent independent risk factors of poor prognosis in patients with AIS.
