Chinese Journal of Practical Nursing 2016;32(4):274-277
Objective To evaluate the effect of IKAP(Information-Knowledge-Attitude-Practice) theory on twin pregnancy women′s psychological states, satisfaction and childbirth outcomes. Methods One hundred twin pregnancy women who had made registrations and antenatal examination were divided into the intervention group and the control group with 50 women in each group according to randorn digit table. The twin pregnancy women in the control group received routine antenatal examinations. In addition, the twin pregnancy women in the intervention group received a special health education with IKAP theory. The twin pregnancy women′s anxiety, depression, birth outcomes and satisfaction were measured and compared between the two groups. Results The score of Self-rating Anxiety Scale (SAS) and Self-rating Depression Scale (SDS) in the intervention group was 27.64±2.86 and 26.53±2.96 one week after delivery, significantly lower than those upon admission, 44.18 ±2.53 and 47.42 ±4.82, the difference was statistically significant (t=5.41, 4.49, P<0.01), also lower than those of the control group, 46.53±2.39 and 39.68±3.78, the difference was statistically significant (t=3.63, 6.82, P<0.01). No significant difference was seen in SAS and SDS scores between upon admission and one week after intervention in the control group (P>0.05). In the intervention group the rate of cesarean section was 29.17% (14/48), and the score of satisfaction was (9.01±0.78), they were also significantly higher than those of the control group, 53.06%(26/49), (7.82±1.44), the difference was significant (χ2=7.701, t=4.806, P<0.05). There were no significant differences in the delivery pregnancy week, volume of bleeding 2 hours postpartum and Apgar score between the two groups (P>0.05). Conclusions The IKAP theory on twin pregnancy women can decrease the anxiety, depression and the rate of cesarean section, and increase patient satisfaction.

Aim The changes and characteristics of liver drug-metabolizing and antioxiditive functions in different status of hepatic injury was investigated to provide support for clinical drug treatments in hepatic fibrosis. Methods Carbon tetrachloride (CCl 4) and other mixture factors were used to make animal model of acute hepatic injury, hepatic fibrosis and cirrhosis, respectively. Subcelluar fractions of liver were prepared by differential centrifugation. Activities of drug-metabolizing and antioxidative enzymes were monitored. Results Levels of phase I enzymes-cytochrome P450 (CYP), CYP1A1 (7-ethoxyresorufin O-deethylation), CYP2E1 (aniline hydroxylation), CYP3A1/2 (erythromycin N-demethylation), and phase Ⅱ enzymes-glutathione S-transferase (GST) were reduced remarkably in hepatic microsomes in different hepatic injury status in a time-dependent manner. However, the activity of CYP2E1 came to be the lowest in acute hepatic injury and recovered gradually when injury time was prolonged. In hepatic fibrosis, the activities of CYP1A,CYP2E1,CYP3A and GST reached 68%,56%,81% and 59%, respectively, of the control, and the functions of antioxidative enzymes in cytosol GST,catalase(Cat) and glutathione peroxidase(GSH-Px) declined to 85%,76% and 54%, respectively, of the control. Conclusion The xenobiotic-metabolizing abilities in liver with hepatic fibrosis were distinctly decreased, which constantly relates with the degrees and the lengths of hepatic injury.

OBJECTIVETo evaluate the efficacy of recombinant human growth hormone (rhGH) in the postoperative treatment of hypospadias in children.
METHODSA total of 84 male children with hypospadias treated by surgery were randomly divided into a control and an rhGH group of equal number, the former treated with antibiotics plus hemostatics with usual wound care, while latter, in addition, by subcutaneous injection of rhGH at 0.2 U/kg/d qd before bedtime for 7 days. Then we compared the two groups in the clinical efficacy, urinary symptoms, peripheral WBC count, C-reactive protein (CRP) level, ratio of CD4+ to CD8+ T lymphocytes in the peripheral blood, contents of serum albumin and total protein, and levels of IgM, IgG and IgA in the serum.
RESULTSThe total effectiveness rates in the rhGH and control groups were 81.0% and 66.7%, respectively, significantly higher in the former than in the latter (P<0.05). The levels of WBC and CRP in the peripheral blood were increased after treatment, but with no significant difference. The contents of serum albumin and total protein were higher before than after surgery. The levels of IgM, IgG and IgA were markedly elevated in the rhGH group as compared with the control. The ratio of CD4+ to CD8+ was significantly increased while the level of CD8+ remarkably decreased after treatment in comparison with pre-treatment.
CONCLUSIONRhGH is effective and safe in the postoperative treatment of hypospadias in children, and its action mechanisms are associated with its promotion of protein synthesis, improvement of negative nitrogen balance and enhancement of immune function.

This study was aimed to compare the immunoregulatory effects of mesenchymal stem cells derived from human umbilical cord amnion (AMSC) and adult bone marrow (BMMSC) in vitro, so as to provide the experimental basis for allogeneic hematopoietic stem cell transplantation in clinic. The AMSC were isolated from human umbilical cord amnion by using digestion with collagenase. They were identified by morphology, growth characteristics, immunophenotyping and differentiation ability. Furthermore, the immunoregulatory effects of AMSC and BMMSC were tested by lymphocyte transformation and mixed lymphocyte reaction. The results showed that AMSC and BMMSC possessed similar biological characteristics such as exhibition of fibroblastic morphology and strong proliferation ability in vitro. Flow cytometric analysis revealed that the AMSC highly expressed CD73, CD90, CD105, but negative for CD34, CD45, HLA-DR, and CD86 of BMMSC. Functionally, they all could differentiate into adipocyte, osteocytes and chondrocytes. Moreover, AMSC could inhibit cellular or nonspecific mitogenic stimuli-induced T cell proliferation with a dose-dependent manner. Reverse transcriptional-polymerase chain reaction also demonstrated expression of the similar immune cytokines in AMSC and BMNSC. It is concluded that the MSC derived from human umbilical cord amnion may be an excellent alternative source for experimental and clinical application.
