Objective To observe the lung inflammation and the expression of T - helper cell related cytokines in respiratory syncytial virus(RSV) infected Balb/c mice pre - sensitized with ovalbumin(OVA). Methods Mice were randomly divided into two series: nonsen-sitized and sensitized animal model with nebulized OVA once a day for 10 days. Each of the series was divided again into two groups: control group,RSV infected group with nasal draping plus nebulizing. All the mice were sacrificed 5 days later of infection. Viral isolation of lung organization was performed in each group. Pulmonary pathological detection and the levels of interleukin - 4(IL-4), interferon-? (IFN- ?) mRNA were evaluated by RT- PCR. Results The RSV were found only in RSV infected groups. The Balb/c mice developed typical interstitial pneumonia after RSV infection. When the mice pre- sensitized were infected with RSV, the pulmonary inflammation, lymphocyte and eosinophils infiltration and cell - collar peribronchiles were more severe in lung organization and bronchiole than those in the single RSV infection group. In the lung organization of control group, there were no mRNA expression of IL - 4 and IFN - ?. The mRNA of IFN -? was expressed in the lung organization of RSV infected groups while had not showed mRNA of IL- 4. In the OVA+ RSV group the mRNA expression of IL - 4 was obvious, while the expresses of IFN -? scarcely. Conclusions Pulmonary inflammation is more severe in the infection after OVA sensitization. RSV infection alone results in a Th1 - like cytokine response, while the infection after OVA sensitization results in Th2 - like response.

Objective To check serum protein of children′s Hirschsprung′s disease(HD) and sift specific protein marker which was used in constructing of HD screening and early diagnosis of serum protein fingerprint model.Methods Surface-enhanced laser desorption/ionization time of flight mass spectrometry(SELDI-TOF-MS) was applied to detect protein mass spectrometry of serum specimens in 82 cases(HD group 42 cases,20 cases of other types of obstruction,healthy control group 20 cases) and data were analyzed by bioinformatics methods(support vector machine).Results 1.For HD group and healthy control group:selected 3 M/Z in 3 221.7,5 639.2,6 884.2 protein markers were selected,HD early screening and diagnostic model was established,3 markers in HD low expression,the expressions of them in HD group and healthy control group were 378.29?273.34,295.65?159.38,444.13?254.06 and 1 428.18?1 192.61,1 039.60?785.64,1 115.72?680.48,respectively.There were significant differences in two groups(Pa0.05).Conclusions The establishment of serum protein fingerprint model of HD by SELDI-TOF-MS support vector machine could screen and diagnose HD early,which is a new method of better specificity,high sensitivity and is worthy of further research and application.

To interpret the traditional Chinese medicine (TCM) theory by the network technology, in order to promote the modernization and programming of studies on compatibility of TCMs. In this paper, efforts were made to express the direct interactions between drugs through the herb-pair network, analyze the community characteristics of the network and its relations with blood-Qi theory, and study the expression of blood-Qi theory on the herb-pair network through prescriptions. According to the findings, the herb-pairs network showed a strong community structure characteristics; Each community is composed of a series of herb pairs with close correlations, and either blood efficacy or Qi efficacy but not both of them. Based on that, the 386 single TCM ingredients involved by the herb-pair network were divided into three types of communities: Blood (B) community, Qi (Q) community and uncertain community. According to the statistical results of 262 prescriptions mapped onto the three types of communities, if a prescription contains single herbs of the Q community, the probability that it contains single herbs o the B community is 99.84%; Meanwhile, there are 140 prescriptions containing single herbs of both the Q community and the B community. The result is completely coincident with the TCM Blood-Qi theory that single herbs belong to both Q and B communities or the B community, because Qi regulation leads to blood regulation, but not vice versa. For example, a patient with hemorrhage due to trauma or blood-heat, Qi tonifying prescriptions may aggravate hemorrhage. In this paper, authors found high-recognition macroscopic network numerical characteristics to network data reference for judging rationality of new prescriptions, and proved human blood and Qi relations from the perspective of data analysis.
