After treatment, IFN-γlevels of the three groups significantly reduced, and IL-4 levels significantly increased (P<0.01). The difference between the treatment group and the control group was significant (P<0.05). The difference between the combined treatment group and the control group was significant (P<0.01). Conclusion Kuijiening Paste acupoint application combined with sulfasalazine can regulate the level of immune cytokine in UC patients of spleen-kidney Yang deficiency type, and receive good clinical efficacy.

Objective To describe the depression of premature infants′ mothers and discuss the related influence factors. Methods A total of 86 premature infants′ mothers completed Edinburgh Postnatal Depression Scale at 3-days postpartum in this descriptive study during August 2014 to January 2015 in Obstetrics and Gynecology Hospital of Fudan University. Results The prevalence of postpartum depression in premature infants′ mothers was 25.6% (22/86). Educational levels, family support, character, and number of abortion of mothers, pregnancy complication, gestational age, birth weight, Apgar score, length of hospitalization, and birth with abnormalities of premature infants were found significantly associated with postpartum depression (P<0.05). By Logistic regression, family support (OR=3.253, 95% CI=1.180-8.966) and length of hospitalization (OR=2.905, 95% CI=1.418-5.952) were the risk factors of the postpartum depression at 3-days after delivery. Conclusions Premature infants′mothers at 3-days postpartum presented with obvious postpartum depression. Psychological intervention should be focused on its influence factors.

Objective To study the psychological nursing on the rehabilitation effect of patients with acute coronary syndrome(ACS)accompanied by depression.Methods 126 ACS patients were divided into the nursing group(64 cases)and the control group(62 cases)randomly.The control group adopted roUtine rehabilitative nursing measurs.While the nursing group received canonical and selective psychological nursing.The Zung Self-rating Depression Scale(SDS)and hamilton depression scale(HAMD)were used to evaluate the their psychological status.The electrocardiogram,clinical symptom and cardiovascular complications were observed and compared.Results The SDS and HAMD scores were different between the nursing group and the control group(P＜0.01)5 weeks after rehabilitative nursing but not before it.The ischemic changes of electrocardiogram,incidence frequency of angina pectoris and cardiovascular complications were significantly decreased in the nursing group compared with the control group(P＜0.05).Conclusion Psychological nursing could not only alleviate the depression of patients with ACS but also could improve the clinical symptoms of these patients and decrease the incidence frequency of cardiovascular events.

AIM:To study the development of autologous peripheral blood stem cells in the fibrous liver after mobilizing recombinant human granulocyte colony stimulating factor and the therapeutical effect of autologous peripheral blood stem cell transplantation.METHODS:Experiments were performed at the Central Laboratory of First Affiliated Hospital,China-Japan Clinical Pathological Center and Central Laboratory of Dalian Medical University from April 2005 to April 2006.①Rat models of hepatic fibrosis were made by injecting carbon tetrachloride subcutaneously.Thirty-two successfully established rat models of hepatic fibrosis were divided into group A,group B,group C and group D with 8 in each group,male and female(half and half).②Rat models of group A were only administered with recombinant human granulocyte colony stimulating factor subcutaneously.Rat models of group B were administered with recombinant human granulocyte colony stimulating factor subcutaneously.Peripheral blood mononuclear cells containing peripheral blood stem cells were collected by density gradient centrifugation.These peripheral blood mononuclear cells were grafted in liver after labeling with PKH26-GL.Rat models of group C did not undergo any management.Serum and hepatic tissues were collected from rat models of group A,group B and group C six weeks later.Successful rat models of liver fibrosis of group D were sacrificed instantly after the last time of carbon tetrachloride administration.Serum and hepatic tissues were collected for measurement.③The alanine aminotransferase,aspartate aminotransferase,albumin and total bilirubin levels and hepatic pathological changes of rat models of all the four groups were measured.Immunofluorescent method was employed to observe the development of autologous peripheral blood stem cells in the liver.RESULTS:A total of 32 rats were involved in the result analysis.①Total bilirubin levels were lower in group A and group B than that of group C(P 0.05).②Hepatic fibrosis was significantly improved in the group A and group B as compared with the group C(P

In this study we implanted magnetically labeled neural stem cells (NSCs) in PD rats and then monitored their survival and migration in the host brain by magnetic resonance imaging (MRI). The mesencephalic NSCs were obtained from the brain of SD rats. Superparamagnetic iron oxide (SPIO) was transferred to NSCs by Lipofectamine transfection. Eighteen PD lesioned rats were selected for transplantation by evaluation of their rotational behavior in response to amphetamine and randomly assigned to 3 groups, i.e., sham group, PBS group and NSCs transplanted group, with 6 rats in each group. MR scanning was performed at 1, 2, 4, 6, 8 and 10 week(s) following transplantation. At the meantime, rotational behavior was assessed in each group. Our results showed that SPIO particles were clearly visible with Prissian blue staining in neurospheres and cells derived from NSCs. The rotational behavior of the NSCs transplanted group was remarkably improved compared with that of sham group and PBS group (P < 0.05). In vivo MR tracking of NSCs showed that SPIO labeling led to a strong susceptibility change of signal 1 week after transplantation on T2 weighted images. And a large circular hypointense signal appeared in the transplanted area on T2* gradient echo images. Ten weeks following transplantation, the hypointense signal on T2 weighted and T2* gradient echo images was still displayed. It is concluded that SPIO particles could label NSCs effectively, and MRI detection of SPIO labeled cells is a promising method and novel approach to analyzing the NSCs following transplantation in the treatment of PD.

Objective To evaluate the influence of preoperative quitting time on coronary artery bypass grafting (CABG) patients with postoperative hypoxemia incidence.Methods 151 patients with coronary bypass surgery and preoperative history of smoking who preparation of CABG in hospital were recruited from September 2011 to September 2013.According to the preoperative smoking cessation time patients were divided into five groups:0 days,1-30 days,31-60 days,61-90 days,more than 90 days.Single factor regression and Logistic analysis were used to analyse the influence of preoperative quitting time on CABG patients with postoperative hypoxemia incidence.Results Age,weight,smoking habit,quitting time,hypertension,diabetes mellitus were risk factors of hypoxemia after coronary artery bypass grafting.Logistic regression analysis showed that age,body weight,smoking habit,smoking time were independent risk factors of hypoxemia after coronary artery bypass grafting.The incidences of hypoxemia of the five groups 0 days,1-30 days,31-60 days,61-90 days and more than 90 days were 55.56％ (15/27),59.26％ (16/27),27.58％ (8/29),22.73％ (5/22),15.63％ (5/32).The incidence of hypoxemia had significant difference (x2=19.212,P ＜ 0.05).Conclusions Age,weight,smoking habit,quitting time were independent risk factors of hypoxemia after CABG.With the quitting time increase,hypoxemia after CABG overall downward trend.Difference quitting time before the operation,the hypoxemia occurred difference rate influence,On the preoperative smoking CABG patients were smoking cessation intervention timely helps to reduce the occurrence of postoperative hypoxemia.

BACKGROUND:Various studies confirm that smoking can contribute to the resorption of periodontal alveolar bone.
OBJECTIVE:To observe the effect of smoking in alveolar bone resorption of periodontitis rat models.
METHODS:A total of 24 rats were randomly divided into three groups. Normal group:rats were normal y fed without any other pre-treatment;Control group:experimental periodontitis model was established using wire ligation method in rats;Experimental group:rat models were given passive smoking during experimental
modeling period. Al rats were sacrificed after 8 weeks of modeling, periodontal tissue were removed. Hematoxylin-eosin staining was used for examining pathological changes in periodontal tissue, and immunohistochemical analysis was done for observing receptor activator of nuclear factor-κB ligand and osteoprotegrin expression.
RESULTS AND CONCLUSION:After 8 weeks of modeling, expression of receptor activator of nuclear factor-κB ligand factor was significantly higher in alveolar bone of rats from experimental group in comparison to control group (P<0.05), whereas expression of osteoprotegerin in alveolar bone was significantly greater in rats from control group when compared to experimental group (P<0.05). This finding suggests that smoking can increase the expression of receptor activator of nuclear factor-κB ligand protein and reduce osteoprotegrin expression in periodontal rats, thus increasing the resorption of periodontal alveolar bone.
