BACKGROUND:For patients in intensive care unit (ICU), mechanical ventilation is an effective treatment to survive from acute illness and improve survival rates. However, long periods of bed rest and restricted physical activity can result in side effects. This study aimed to investigate the feasibility of early rehabilitation therapy in patients with mechanical ventilation. METHODS:A randomized controlled trial was carried out. Sixty patients, with tracheal intubation or tracheostomy more than 48 hours and less than 72 hours, were admitted to the ICU of the Affiliated Hospital of Medical College, Qingdao University, from May 2010 to May 2012. These patients were randomly divided into a rehabilitation group and a control group. In the rehabilitation group, rehabilitation therapy was performed twice daily, and the training time and intensity were adjusted according to the condition of the patients. Early rehabilitation therapy included heading up actively, transferring from the supine position to sitting position, sitting at the edge of the bed, sitting in chair, transferring from sitting to standing, and ambulating bedside. The patient's body mass index, days to first out of bed, duration of mechanical ventilation, length of ICU stay, APACHE Ⅱ score, highest FiO2, lowest PaO2/FiO2 and hospital mortality of patients were all compared between the rehabilitation group and the control group. The differences between the two groups were compared using Student's t test. RESULTS:There was no significant difference in body mass index, APACHE Ⅱ score, highest FiO2, lowest PaO2/FiO2 and hospital mortality between the rehabilitation group and the control group (P>0.05). Patients in the rehabilitation group had shorter days to first out of bed (3.8±1.2 d vs. 7.3±2.8 d; P=0.00), duration of mechanical ventilation (5.6±2.1 d vs. 12.7±4.1 d; P=0.005) and length of ICU stay (12.7±4.1 d vs. 15.2±4.5 d; P=0.01) compared with the control group. CONCLUSION:Early rehabilitation therapy was feasible and effective in improving the outcomes of patients with mechanical ventilation.

To study the effect of the combined administration of different doses of Glycyrrhizae Radix et Rhizoma and Atractylodis Macrocephalae Rhizoma on the proliferation of DFMO-treated intestinal epithelial cells (IEC-6) and p53, p21 mRNA and protein expressions, in order to define the molecular basis for the effect of the combined administration of different doses of Glycyrrhizae Radix et Rhizoma and Atractylodis Macrocephalae Rhizoma on the cell proliferation. The effect of the drugs on the cell division rate and cell cycle of IEC-6 cells was detected by FCM. Quantitative Real-time PCR (qRT-PCR) was used to analyze the effect of the drugs on mRNA of p2l and p53 related to IEC-6 proliferation. Western blot was used to analyze the effect of the drugs on p2l and p53 protein expressions of IEC-6 cells. Atractylodis Macrocephalae Rhizoma could increase p53, p21 mRNA and proteins expression in DFMO-treated IEC-6 cells. The combined administration of different ratios of Atractylodis Macrocephalae Rhizoma and Glycyrrhizae Radix et Rhizoma could significantly down-regulate Atractylodis Macrocephalae Rhizoma's effect on p53, p21 mRNA and proteins expression in DFMO-treated IEC-6 cells and promote the proliferation of IEC-6 cells. The combined administration of Atractylodis Macrocephalae Rhizoma and Glycyrrhizae Radix et Rhizoma could down-regulate Atractylodis Macrocephalae Rhizoma's effect on DFMO-treated intestinal epithelial cells (IEC-6).

OBJECTIVETo evaluate the efficacy of targeted tidal volume ventilation in the treatment of severe neonatal respiratory distress syndrome (RDS).
METHODSEighty-four neonates with severe RDS between June 2008 and January 2010 were randomly assigned to 3 groups according to the ventilation mode: synchronized intermittent positive pressure ventilation plus volume guarantee (SIPPV+VG; n=31), high frequency oscillation ventilation (HFOV; n=23) and intermittent mandatory ventilation (IMV; n=30). The oxygenation status, the durations of oxygen exposure and ventilation and the incidence of complications were observed.
RESULTSThe oxygenation status (P/F and a/APO2) in the SIPPV+VG and the HFOV groups was improved significantly 12 hrs after ventilation (P<0.05). While in the IMV group, the oxygenation status was not improved until 24 hrs after ventilation. The durations of oxygen exposure and ventilation in the SIPPV+VG and the HFOV groups were shorter than in the IMV group (P<0.05). The incidences of air leak syndrome and ventilation-associated pneumonia (VAP) were lower in the SIPPV+VG and the HFOV groups than in the IMV group (P<0.05). The incidence of severe intracranial hemorrhage in the HFOV group was higher than in the other two groups (P<0.05).
CONCLUSIONSCompared with IMV, SIPPV+VG and HFOV can improve the oxygenation status more quickly, shorten the ventilation duration and decrease the incidences of air leak syndrome and VAP in neonates with severe RDS.

OBJECTIVE:
To explore the correlation between the interleukin-17 (IL-17) level of peripheral blood and aggression of bipolar mania.
METHODS:
Thirty-six patients of bipolar mania were selected as experimental group by DSM-IV-TR and received treatment with quetiapine and lithium. Thirty-six healthy volunteers with similar age and gender were selected as control group. The level of IL-17 at baseline in each group and the level of IL-17 in the experimental group after treatment for 2, 4 and 8 weeks were detected by ELISA.
RESULTS:
The level of IL-17 in experimental group at baseline, after treatment for 2 and 4 weeks were all significantly higher than that in control group. After 8 weeks treatment, there was no significant difference between the two groups (P > 0.05). After 2, 4 and 8 weeks treatment, the total score and aggression score of Young Mania Rating Score (YMRS) were significantly lower than the baseline level (P < 0.05). In experimental group, the level of IL-17 was positively correlated with the two scores of YMRS at baseline (P < 0.05).
CONCLUSION
Bipolar mania may be related to the up-regulation of IL-17. The level of IL-17 is related to the severity of manic symptoms at baseline, especially aggression symptom.

To provide theoretical basis for breeding good variety of Dendrobium denneanum, agronomic and qualitative characters of 4 different lines and relationships among them were studied. The stem length, stem diameter, leaf length, leaf width, length/ width ratio and leaf area were measured. The single fresh and dry stem was weighed and drying rate was calculated. The contents of polysaccharides and total alkaloids were determined by sulfuric acid-phenol colorimetry and acid-dye colorimetry, respectively. The correlations between characters were analyzed. The results showed that differences in major agronomic characters between four lines were significant. The plant types of dq-1 and dq-2 were higher, dq-3 was medium and dq-4 was lower. The fresh weigh of stem and content of polysaccharides were the highest in dq-2, 7.81 g and 14.33%. While the highest content of total alkaloids and was 0. 486% in dq-3. There were significant correlations between agronomic characters, but these characters had low or non correlations with qualitative characters such as polysaccharides and total alkaloids. It was shown that the content of polysaccharides and total alkaloids were significantly different among 4 lines of D. denneanum, which could be selected for different uses.

BACKGROUNDMany studies on periostin have focused on its role in tumors and vascular reconstruction. However, the effect of periostin on stem cell function remains unclear. The aim of this study was to enhance vitality in adipose-derived stem cells (ADSCs), the effect of periostin on the function of ADSCs was observed.
METHODSHuman ADSCs (hADSCs) were isolated from human adipose tissue by collagenase I digestion and collected in multi-periods for in vitro culture. CD29, CD34, CD44, CD45 and CD105 were detected by flow cytometry. In addition, directed differentiation of hADSCs was induced using adipogenic, osteogenic and chondrogenic induction mediums. The induced morphological changes were observed using oil red O, Alizarin red and alcian blue staining. Periostin was administered to hADSCs in an acidic environment. The treatments of cells were divided into three groups: a periostin group (P); an acidic control group (A); a normal group (N). Then the resulting cell proliferation and migration were detected using a Cell Counting Kit-8 (CCK-8) and a transwell chamber assay, respectively.
RESULTSThe detection rates of CD29, CD44, CD105, CD34 and CD45 were 98.89%, 93.73%, 86.99%, 0.19% and 0.16%. The specific staining of cells was positive after induction culture. The mean absorbance of the cells in group P and A at 12 hours were 16.67% and 22.22% greater than group N, respectively (P < 0.01). The mean absorbance of cells from group P was 20.00% greater than that of group A at 48 hours (P < 0.05). The mean number of migratory cells per visual field in group A was 50.38% lower than that in group N (P < 0.05). The migratory cell number in group P was 119.98% greater than that in group A (P < 0.05).
CONCLUSIONSThe acidic environment impacted hADSC proliferation and inhibited cell migration. However, periostin was able to promote the proliferation and migration of hADSCs despite the acidic environment.
