Objective To study the effects of intestinal trefoil factor(ITF) on inducible nitric oxide synthase(iNOS),tumor necrosis factor-?(TNF-?) and NO density in neonatal rat model of necrotizing enterocolitis(NEC). Methods Forty neonatal rats were randomly divided into five groups: Group A, NEC+ ITF 0.5 mg; Group B, NEC+ ITF 0.2 mg; Group C, NEC+ N.S 0.5 ml; Group D, NEC+ N.S 0.2 ml; Group E, normal control. NEC model was established as following method: one-day old Wistar rats were put into 100%carbon dioxide for 5 min and then 100% oxygen for 5 min before returned to their mothers. This was done once daily for 3 days. On the 4th day, all rats were sacrificed and the intestinal tissue located at the boundary of ileum and cecum was obtained for histological examination by HE staining and iNOS, TNF-? and NO level by immunohistopathology. Results iNOS was found negative in group A, B and E, but positive in group C and D. The density of TNF-? were significantly decreased in group A[(30.515?2.731) pg/mg?pro] and B[(32.229? 4.978) pg/mg?pro] than that in group C[(39.957?8.283) pg/mg?pro] and D[(39.960?8.374) pg/mg?pro, P 0.05)]. The density of NO were significantly decreased in group A[(0.37?0.07) ?mol/mg tissue] and B[(0.54?0.08) ?mol/mg tissue] than that in group C[(0.76?0.01) ?mol/mg tissue] and D[(0.82? 0.04) ?mol/mg tissue ( P 0.05)]. The TNF-? and NO expression showed no difference among group A and B, group C and D. The pathological lesions indicate that severe intestinal tissue necrosis in group C and D, and mild in group A and B. Conclusions Intestinal inflammation could be ameliorated after ITF injection hypodermically or intraperitoneally. ITF may provide a brand-new way for the management of NEC in neonatal rats.

Objective To explore the current status of sexual education and real needs of college freshmen in Kunming.Methods By applying random sampling,350 students from three universities in Kunming were investigated by seff-administered questionnaire,and 310 valid questionnaires were recovered.Fesults 23.9％ students confirmed that the schools do not provide courses related to sexual health,and 22.9％ of the surveyed students claimed that they even did not heard any sexual education courses in their schools.The main sources of students to acquire information in terms of sexuality and sexual health are network television,video magazines,friends and classmates.Both male and female students are more acceptable to carry out sex education lectures.There were significant differences between male and female students in the form of obtaining sexual education,the content of sexual education and the demand of sexual education in three aspects (P＜0.05).Girls tend to carry out sexual education in the form of major courses,but boys tend to the form of playing video or distributing books and periodicals (P＜0.05).Girls tend to obtain the courses on sexually disease,AIDS,heterosexual intercourse,or love psychology,but boys tend to contraceptive knowledge and skilIs,or Sexual value orientation (P＜0.05).Girls are more likely to acquire the knowledge of masturbation,sexual health,or sexual health,but boys prefer to the knowledge of sexual psychology,parasexuality,or homosexuality (P＜0.05).Conclusion As a main body of educational institute for young people,all universities should provide training courses related to sexuality and sexual health at the early stage of higher education in order to equip college students with essential knowledge and skills to have safer and positive impact on their college studies.

Objective To evaluate the effects of transtheoretical model and motivational interviewing on medication?compliance in patients with percutaneous coronary intervention (PCI) post-operation. Methods One hundred patients with PCI post-operation were randomized into the observation group (n = 50) and the control group (n = 50). The medication compliance, 6-min walk test and major adverse cardiovascular events (MACE) were compared between two groups. Results At 1 month, 3 months and 6 months post-intervention, the medication compliance in the observation group was significantly increased (P < 0.05, respectively). The 6-min walk test in the observation group was significantly increased compared with the control group. The MACE rate in the observation group and the control group was 10.0% and 36.0%, respectively, with significant difference (P< 0.05). Conclusion The transtheoretical model and motivational interviewing can effectively increase the medication compliance, improve the postoperative rehabilitation, and decrease the MACE rate.

Objective To analyze the influence of intestinal trefoil factor(ITF) on Bim and Bcl-xl gene expression in neonatal rats with necrotizing enterocolitis(NEC),and to discuss the protective machanism of ITF on NEC.Methods Thirty neonatal rats were divided randomly into control group,NEC group and ITF group.NEC group were given intraperitoneal injection of saline 0.2 ml after NEC model of neonatal rats were established.ITF group were given intraperitoneal injection ITF 0.2mg after NEC model of neonatal rats were established.On the 4th day,all the subjects were put to death.We made HE stainting of the slice and made a histopathological examination and immunohistochemical method to detect Bim and Bc1-xl genes expression,and make image analysis.Results The pathological lesions indicated that intestinal tissue necrosis was severe in NEC group,which median was 3 point,but obviously lessen in ITF group,which median was 1 point,with ITF interfering.Image analysis showed the NEC group Bim gene expression (7.87 ± 0.14) higher than those in the control group (2.15±0.28) and ITF group (3.27±0.34),there were significant differences between 3 groups(P<0.05).Bcl-xl gene expression(11.23±0.22)in ITF group was higher than that in control group(1.89±0.28) and NEC group(2.51±0.13),there were significant differences between 3 groups(P<0.05).Conclusions Intestinal injury was ameliorated after ITF was injected intraperitoneally,ITF may protect the intestinal injury of neonatal rats with NEC by changing the Bim gene and Bc1-xl gene expresstion ratio.

OBJECTIVEThis study aimed to observe the postoperative pain rate and degree of pain in preschool children with cleft lip and palate, and investigate the effect of nursing intervention on pain relief.

METHODSA total of 120 hospitalized cases of three- to seven-year-old preschool children with cleft lip and palate were selected from May to October 2011. The subjects were randomly divided into the control group and experimental groups 1, 2, and 3. The control group used conventional nursing methods, experimental group 1 used analgesic drug treatment, experimental group 2 used psychological nursing interventions, and experimental group 3 used both psychological nursing intervention and analgesic drug treatment. After 6, 12, 24, and 48 h, pain self-assessment, pain parent-assessment, and pain nurse-assessment were calculated for the four groups using the pain assessment forms, and their ratings were compared.

RESULTSThe postoperative pain rates of the four groups ranged from 50.0% to 73.3%. The difference among the four groups was statistically significant (P < 0.001). The differences among the control group and experimental groups 1 and 2 were not statistically significant (P = 0.871), whereas the differences among experimental group 3 and the other groups were statistically significant (P < 0.001).

CONCLUSIONPostoperative pain in preschool children with cleft lip and palate is common. Psychological nursing intervention with analgesic treatment is effective in relieving postoperative pain.

Aim To investigate the mechanism of the melanoma B16 F10 cells proliferation induced by Lico-chalcone A in vitro. Methods The proliferation of B16 F10 cells induced by Licochalcone A was deter-mined by SRB method. The morphological changes were observed using Giemsa staining under the phase contrast microscope equipped with a digital camera. The melanin level was assessed by colorimetric meth-od. The apoptotic rate was determined by Annexin V-FITC/PI assay. Cell cycle distribution was determined by flow cytometry. The mRNA expression levels of B cell lymphoma/lewkmia-2 ( Bcl-2 ) , Bcl-2 associated X protein ( Bax) , the cell cycle protein CyclinE2 and cyclin-dependent kinase-2 ( CDK2 ) CDK2 were detec-ted using Q-PCR analysis. Results The proliferation of B16 F10 cells treated with Licochalcone A was effec-tively inhibited in a concentration and time-dependent manner. A clear morphological change was observed with the increasing concentration of Licochalcone A in B16F10 cells, the dendrite-like projections changed to the narrowing ball shape, which was associated with the increasing melanin level. The low concentration of Licochalcone A could induce B16F10 differentiation, and the high concentration of Licochalcone A could in-duce B16F10 apoptosis, which was accompanied with the increasing G1 phase in cell cycle. The mRNA ex-pression levels of Bcl-2 /Bax, CyclinE2 and CDK2 were markedly reduced. Conclusion Licochalcone A can effectively inhibit the proliferation of B16 F10 cells, induced cell cycle arrest at G1 phase, and fur-ther induced differentiation and apoptosis.
