Objective To explore the peripheral blood T lymphocytes cell level in different grades of cerebral gliomas pa-tients at the time of before and after operation and its clinical significance .Methods A total of 80 cases of brain tumor patients from February 2010 to February 2012 in this hospital were chosed as study objects ,included 57 cases of glioma ,23 cases of other brain tumors ;57 cases of glioma were divided into 19 cases of low grade group and 38 cases of high grade group accorded to WHO grading standards ,and 50 cases of healthy people in same period were selected as control group .Venous blood in three groups were extracted at 1st day and 1st week after operation ,to detected the level of T lymphocyte subsets in peripheral blood and analyze the relationship between the different grade gliomas and prognosis .Results The peripheral blood CD3 + ,CD4 + ,CD4 + /CD8 + in control group were significantly higher than that of other brain tumor group and the glioma group ,CD8 + was significantly lower than that of the two groups(P< 0 .05) .Compared with other tumor group ,peripheral blood CD3 + ,CD4 + ,CD4 + /CD8 + in glioma group de-creased significantly ,CD8 + increased significantly(P< 0 .05) ;before and after the operation ,the CD3 + and CD4 + /CD8 + levels were significantly higher in low grade group than in the high grade group ,CD8 + was significantly lower in low grade group than in the high grade group(P< 0 .05) ,at the time of 1st week after operation ,CD3 + and CD4 + /CD8 + increased ,CD8 + decreased significant-ly of two groups when intra-group comparison (P < 0 .05) .The median survival time were 31 months in low grade group and 13 months in high grade group ,and the singnificance was found in two groups(P< 0 .05) .The median survival time were 34 months in CD4 + /CD8 + > 1 group and 17 months in CD4 + /CD8 + < 1 group ,the singnificance was found in two groups(P< 0 .05) .Conclusion The immune function of patients with brain glioma is inhibited ,the higher the malignancy of the tumor ,the more obvious of im-mune inhibition ;T lymphocyte subsets level could be used as evaluating index of malignant degree and prognosis of brain glioma .

Objective To observe the clinical efficacy ofTiaozhong YifeiPrescription combined with Western therapy for treatment of cough variant asthma (CVA) remission. Methods Totally 90 patients with CVA remission were randomly divided into TCM group, Western therapy group and TCM and Western therapy group, 30 cases in each group. TCM group was givenTiaozhong YifeiPrescription, 1 dose per day, morning and evening; Western therapy group was given salmeterol xinafoate and fluticasone propionate powder for inhalation, each 1 suction, 2 times a day, inhalation; a mixture ofTiaozhong YifeiPrescription and xinafoate and fluticasone propionate powder for inhalation was given to TCM and Western therapy group, the same as above, continuous treatment for 12 weeks. TCM syndrome score, EOS, IgE, pulmonary function and safety index were observed in the three groups before and after treatment. The recurrence rate and the number of colds after three-month treatment were observed.Results TCM syndrome scores in the three groups decreased after treatment (P<0.05). There was statistical significance between TCM group and TCM and Western therapy group after treatment (P<0.05). The total effective rate of TCM group was 96.67% (29/30), 100.00% (30/30) of Western therapy group, 76.67% (23/30) of TCM and Western therapy group, with statistical significance (P<0.05). After three-month treatment, 1, 0 and 11 cases relapsed in TCM group, TCM and Western therapy group and Western therapy group, respectively, with statistical significance (P<0.001). Compared with the Western therapy group, the number of colds in the TCM group and TCM and Western therapy group significantly decreased (P<0.05). Compared with before treatment, IgE decreased significantly (P<0.05). There was no significant difference in EOS among the three groups before and after treatment (P>0.05). After treatment, the maximum expiratory flow in TCM and Western therapy groupwas higher than that before treatment and lower than that in the Western therapy group (P<0.01), and the other lung function indexes were not statistically significant (P>0.05). 1 mild adverse reaction was found in the TCM and Western therapy, and no obvious adverse reactions were found in other groups (P<0.05).ConclusionTiaozhong Yifei Prescription has good clinical efficacy for CVA.

Soil archaea and fungi play important roles in the greenhouse soil ecosystem. To develop and apply rich microbial resources in greenhouse ecological environment, and to understand the interaction between microbes and plants, we constructed archaeal 16S rRNA and fungal 18S rRNA gene libraries to analyze the compositions of archaeal and fungal communities. Total greenhouse soil DNA was directly extracted and purified by skiving-thawing-lysozyme-proteinase K-SDS hot treatment and treatment of cetyltriethylammnonium bromide (CTAB). After PCR amplification, retrieving, ligating, transforming, screening of white clones, archaeal 16S rRNA and fungal 18S rRNA gene libraries were constructed. The sequences of archaea and fungi were defined into operational taxonomic units (OTUs) when 97% similarity threshold for OTU assignment was performed by using the software DOTUR. Phylogenetic analysis showed that crenarchaeota and unidentified-archaea were the two major sub-groups and only a few of euryarchaeota existed in the archaeal clone library, total 45 OTUs. All the crenarchaeota belonged to thermoprotei; except for Basidiomycotina, the other four sub-group fungi were discovered in the fungal library, total 24 OTUs. The diversities of archaea were very abundant and a few euryarchaeota (methanebacteria) existed in the archaeal clone library, it might be directly related to the long-term high temperature, high humidity, and high content of organic matter. The limitation of oxygen was the other reason for causing this phenomenon; Ascomycotina (over 80%) was the dominant sub-groups in fungal library. It was because most of the plant fungal diseases belonged to soil-borne diseases which gone through the winter by the ways of scierotium or perithecium and became the sources of primary infection.
