The study is aimed to make the most of available space of Dendrobium officinale cultivation facility, reveal the yield and functional components variation of stereoscopic cultivated D. officinale, and improve quality, yield and efficiency. The agronomic traits and yield variation of stereoscopic cultivated D. officinale were studied by operating field experiment. The content of polysaccharide and extractum were determined by using phenol-sulfuric acid method and 2010 edition of "Chinese Pharmacopoeia" Appendix X A. The results showed that the land utilization of stereoscopic cultivated D. officinale increased 2.74 times, the stems, leaves and their total fresh or dry weight in unit area of stereoscopic cultivated D. officinale were all heavier than those of the ground cultivated ones. There was no significant difference in polysaccharide content between stereoscopic cultivation and ground cultivation. But the extractum content and total content of polysaccharide and extractum were significantly higher than those of the ground cultivated ones. In additional, the polysaccharide content and total content of polysaccharide and extractum from the top two levels of stereoscopic culture matrix were significantly higher than that of the ones from the other levels and ground cultivation. Steroscopic cultivation can effectively improves the utilization of space and yield, while the total content of polysaccharides and extractum were significantly higher than that of the ground cultivated ones. The significant difference in Dendrobium polysaccharides among the plants from different height of stereo- scopic culture matrix may be associated with light factor.

Objective To investigate the variation of biomarker of coagulation, anti-coagulation, fibrinolysis in elderly critical patients and find out whether they are related to the disease severity. Methods Sixty-seven patients were no less than 60 years old. Eligible criteria: coincidence with the diagnostic criteria of systemic inflammatory response syndrome (SIRS) and APACHE Ⅱ score was no less than 10 scores. Blood sample was drawn from the venous for the test of biomarker (APTT, PT, TT, D-D, Fib, AT-Ⅲ , PC, PAI-1). According to the existent status,all the patients were divided into two groups:survival group (43 cases) and death group(24 cases) ,meanwhile,according to the diagnostic criteria of MODSE,all the patients were divided into MODSE group (30 cases) and non-MODSE group (37 cases). Results There were significant differences in APACHE Ⅱ score between MODSE group and non-MODSE group, survival group and death group [(25.83 ± 1.19) scores vs(18.1±20.73) scores and(18.81±0.72) scores vs(26.50 ± 1.42) scores](P <0.01). The PT and D-D in MODSE group anti death group were higher than those in non-MODSE group and survival group, the differences were significant (P <0.05),while the activity of AT-Ⅲand PC in MODSE group and death group were lower than those in non-MODSE group and survival group, the differences were significant (P <0.05). The PT,D-D and PAI-1 were positively correlated to APACHE Ⅱ score (related coefficients were 0.328, 0.308, 0.335,P <0.05). The AT-Ⅲ and PC were negatively correlated to APACHE Ⅱ score (related coefficients were -0.469, -0.559,P <0.01). Conclusions The abnormality of eoagnlation-fibfinolysis system exists in elderly critical patients. The extended PT, elevated D-D and PAI-1 ,descended PC and AT-Ⅲ are the hints of disease severity and poor prognosis.

Objective The combination of vasopressin and epinephrine has long been thought to be more effective then epinephrine alone in cardiopulrnonary resuscitation (CPR), evidence is not enough to make such a clinical recommendation. This meta-analysis compared the efficacy of vasopressin and epinephrine used together versus epinephrine alone in cardiac arrest (ca) in order to verify the truth. Method MEDLINE and EMBASE were searched for the data of randomized trials in comparing the results of co-administration of vasopressin and epinephrine with epinephrine alone in adults with cardiac arrest. The primary outcome was the restoration of spontaneous circulation (ROSC). Results Six randomized trials in 485 articles were analyzed. We failed to get the results supporting the effectiveness of this combination therapy, except for the rate of 24 hours survival (OR: 2.99,95%CI:1.43 ~ 6.28). No evidence supported that vasopressin combined with epinephrine was better than epinephrine alone in ROSC. Conclusions This systematic review indicates the combination of vasopressin and epinephrine is better for the rate of 24 hpurs survival in only 122 patients. Further investigation is needed to support the use of combination therapy for cardiac arrest.

Objective To analyze the expression of synaptophysin (SY) in hippocampal dentate gyrus of rats with hypoxic-ischemic brain damage(HIBD) after the injection of bone marrow stromal cells(BMSCs) and its supernatant into the lateral ventricle and to explore the mechanism of potential effects. Methods Eighty 7-day-old sprague-dawley(SD) rats were randomly divided into sham group, control group, cell group and supernatant group, with 20 rats in each group. The HIBD model was established via the ligation of left carotid arteries followed by 2-hour hypoxia. One week later, control group was injected with 0.01 mol/L PBS via the left ventricle. Meanwhile, cell and supernatant group were injected with BMSCs and supernatant harvested from BMSC culture, respectively, via the same route. For spam group, the left carotid arteries were separated but not ligated, and no hypoxia treatment was imposed on this group. They also received 0.01mol/L PBS injection one week post surgery. After 8 weeks, the expression of SY in the dentate gyrus of rats was measured. Results Compared with sham group, model group showed significantly lower IOD (integral optical density) of SY positive material in the dentate gyrus(P < 0.05). Compared with model group, supernatant group and cell group exhibited significantly increased IOD values (P < 0.05), but there was no significant difference between cell group and supernatant group (P > 0.05). Conclusions BMSCs and supernatant injected via the lateral cerebral ventricle can increase SY expression in the hippocampal dentate gyrus of HIBD rats and promote synapse formation. The mechanism of this effect may be related to cytokine secretion by BMSCs which promotes synapse formation.
