Objective To study the mechanism of GuiJi cream in dispelling effects on corrupt microorganism.Methods A total of 90 full-layer skin injured rats were served as test model. The effects of Guiji cream on collagen type Ⅰ (C Ⅰ), matrix metalloproteinase-1 (MMP-1) and MMP-3 in granulation tissue of wound were observed with immunohistochemistry technique and image-analysis system at various stages of healing. Results The expression of C Ⅰ was obviously increased and the level of MMP-1 and MMP-3 increased at the early stage and kept at a high level from day 3 to day 10. Conclusion The mechanism of GuiJi cream for dispelling effects on corrupt microorganism was increasing the C Ⅰ content in granulation tissue of wound through inhibiting the secretion of MMP- 1.

Objective: To explore the effects of Polygonatum odoratum on body based on metabonomics. Methods: The ultra performance liquid chromatography coupled with mass spectrometry (UPLC-MS) and principle component analysis(PCA) and orthogonal partial least squares discriminant analysis(OPLS-DA) were used to evaluate the changes of endogenous substances in rats after intragastric administration of Polygonatum odoratum. Results: Significant differences between the control group and administration group were observed in PCA and OPLS-DA model. Five potential biomarkers between control group and administration group were identified. The relative content of Alpha-Tocotrienol, PC(14:1(9Z)/14:1(9Z)), Stearic acid, Theasapogenol A, Docosahexaenoic acid increased. Conclusion: The biomarkers had many beneficial activities, so the Mongolian medicine Polygonatum odoratum had the function of health care. Key words: Mongolian drug; Polygonatum odoratum; Biomarkers; UPLC-MS

ObjectiveTo explore the action of the psychointervension for older hypertensives in community.Methods50 older hypertensives were divided into the experimental group and the control group (with 25 cases in each group),the former received psychointervension combined body therapy and the later only received body therapy. A half of a year experiment period was made. Differences between two groups in blood pressure and SCL-90 before and after the experiment were compared and evaluated.ResultsThe mentation of older hypertensives is worse than the normal. There are distinct differences between two groups in the improvement of mentation and the stability of blood pressure (P<0.01). Conclusions It is an active effect to strengthen psychointervension for therapy of older hypertensives in community.

The status of marine bioresources and the marine eco-environment issues were summarized and discussed, and the strategies for the development of Chinese marine bioresources in the future were proposed. The degradation of marine eco-environment and unreasonable exploitation of the resources resulted in acute decline of Chinese marine bioresources. The feasible stratagies for the sustainable use of marine bioresources should be to intensify the basic research on marine bioresources science, to strengthen the protection of the marine environment and conservation of marine living resources, and to exploit and utilize marine bioresources scientifically and reasonably by using high-technology including marine biotechnology.

To study the preventive effect of sophocarpine (Soc) on dextran sulfate sodium (DSS)-induced colitis in mice, in order to analyze the influence of Soc on toll like receptor 4 (TLR4)/mitogen-activated protein kinases (MAPKs) and janus tyrosine kinase 2 signal transducer and activator of transcription 3 (JAK2/STAT3) signal pathways in mice intestinal tissues. The mice was given 2.5% DSS for 6 days to induce the acute colitis model. The Soc-treated group was intraperitoneally injected with sophocarpine 30 mg · kg(-1) · d(-1) since the day before the experiment to the end. The disease activity index (DAI) was assessed everyday, and the colonic morphology and histological damage were observed with HE staining. The mRNA expressions of tumor necrosis factor-α (TNF-α), interleukin-1β (IL-1β) and interleukin-6 (IL-6) were detected by real-time RT-PCR. The changes in key protein kinase p38 mitogen-activated protein kinase (p38MAPK), c-Jun NH2-terminal protein kinase1/2 (JNK1/2), extracellular signal-regulated kinase1/2 (ERK1/2), JAK2, STAT3 in TLR4/MAPKs and JAK2/STAT3 signaling pathways were detected by western blot. The result showed that the model group showed statistical significance in body weight, DAI, colon length and histopathological changes compared with the normal group (P <0.05); however, the Soc-treated group showed significant improvements in the above indexes compared with the model group (P <0.05). TNF-α, IL-1β and IL-6 in the model group was significantly higher than that in the normal group (P <0.05), but lowered in the Soc-treated group to varying degrees (P <0.05). In the normal group, the expressions of TLR4 and the phosphorylation of P38, JNK1/2, JAK2, STAT3 were at low levels; in the model group, the phosphorylation of P38, JNK1/2, JAK2, STAT3 increased; the Soc-treated group showed a decrease in TLR4 expression compared with the model group, with notable declines in the phosphorylation of TLR4, P38, JNK1/2, JAK2, STAT3. These findings indicate that Soc can inhibit TLR4/MAPKs, K2/STAT3 signaling pathway activation, reduce the expression of proinflammatory cytokines TNF-α, IL-1β and IL-6 and relieve inflammatory reactions, so as to effectively prevent experimental colitis.

0.05).There was significant difference in the 3-year survival rate between A and C group. Conclusions The 3-year survival rate was dramatically increased with combined therapy mainly by cisplatin, the dose of 60～80mg is tolerant for the elderly aged above seventy years, and perioperation complications can be cured.

Objective　To investigate the effect of breast milk and some other kinds of infant foods on the adhesion of EPEC to Hela cells and intestinal mucosa so as to understand the possible protective mechanism of breast-feeding in the intestine of infants. Methods　The adhesion of EPEC to Hela cells and intestinal mucosa were examined by cell culture, bacterial adherence test, light and electron microscopy in the mediums that contain breast milk, cow's milk and formula milk or contain ecal filtrate of the infants fed by breast milk and formula milk respectively. Results　Adhesive index for EPEC to Hela cells was significantly lower in the medium containing breast milk than in control and so did in the fecal medium containing breast fed infants than artificial feeding infants. Conclusion　Breast milk may inhibit the adhesion of EPEC to infant intestine.
