1.Analysis of higher vocational nursing students participating in opening professional social practice
Chinese Journal of Practical Nursing 2013;29(32):13-15
Objective To analyze the significance of higher vocational nursing students participating in opening professional social practice,and to explore the effective way of combining social practice with professional learning and clinical practice.Methods After completing the opening professional social practice in summer,the reflection diaries of 30 nursing students were analyzed and the concerns were refined.Questionnaire survey about self assessment of comprehensive effect of the practice of nursing students were conducted.Results Nursing operation and soft skills were mostly concerned by nursing students' in opening professional social practice.Vocational learning,occupation of responsibility,and the occupation ability were improved by practical activities.Conclusions Nursing students who participate in opening professional social practice before clinical work,can re-understand the professional learning,adapt and integrate themselves into clinical practice through the perception of clinical nursing work.

3.Effects of purslane herb on stress ability of aging mice induced by D-galactose
Journal of Integrative Medicine 2004;2(5):361-3
OBJECTIVE: To investigate the effects of purslane herb aquenous extracts (PHAS) on the stress ability of aging mice induced by D-galactose. METHODS: We observed the survival time to hypoxia and heat survival rate of the mice treated with different doses of PHAS and vitamin E. The contents of lipofuscin and malondialdehyde (MDA), and the activity of superoxide dismutase (SOD) and catalase (CAT) in the brain and liver of the mice were tested. RESULTS: As compared with vitamin E, three doses of PHAS (1.6, 0.8 and 0.4 ml/d) prolonged the survival time to hypoxia and the pole climbing time and increased the heat survival rate, and the 0.8 ml/d PHAS had the best effect. In the group of 0.8 ml/d PHAS, the activity of SOD and CAT decreased less, and the contents of lipofuscin and MDA decreased significantly. The effect of vitamin E was not as good as the PHAS. CONCLUSION: PHAS can prevent the stress ability of the aging mice. One of its mechanisms may be increasing the activity of SOD and CAT, hence decreasing the damage of the oxidation products to the body.
4.Effect of PTTG on the growth and fluorouracil sensitivity of cholangiocarcinoma cell Line QBC939
Chinese Journal of General Surgery 2001;0(08):-
Objective To investigate the effct of PTTG gene on the growth and sensitivity to 5-FU of cholangiocarcinoma cell.Methods The pcDNA3.1-PTTGas that contained full-length antisense PTTG,and pcDNA3.1(+) was transfected into the cholangiocarcinoma cell line QBC939.We successfully established and identified cell sublines tQBC939(PTTG-),tQBC939(pcDNA3.1).Cell growth curve was mapped out,cell proliferation rate was assessed by MTT assay and cell cycle percentage was counted by flow cytometry.After treatment with 5-FU,cell survival rate was assessed by MTT assay and IC50 was calculated.Flow cytometry and Hoechst staining were used to demonstrate discrepancy of cell apoptosis rates.Results Compared with other two groups,tQBC939(PTTG-) grew more rapidly and had a higher proportion of cells in S phase,whereas less cells in G2/M phase(P
6.Information needs and influencing factors for female breast cancer patients
Chinese Journal of Hospital Administration 2012;28(3):172-175
Objective To explore the extent of information needs and influencing factors among breast cancer patients.Methods Choose patients by random with a questionnaire for malignant breast cancer patients(Chinese edition),and analyze the influencing factors in a multiple linear regression.Results The total extent of information needs among the patients is 65.615±20.854,with much stronger needs among those with younger age,higher income and/or suitable for surgery.Conclusion Information needs of the patients were found to depend on their various social attributes.Based on this founding,recommendations were made in terms of contents of information needs,care for vulnerable groups,and channels of information communication.
7.Review of arsenic trioxide effect on solid cancer
Academic Journal of Second Military Medical University 2003;24(4):440-443
Clinical trials have demonstrated that arsenic trioxide(As2O3) was effective in the treatment of acute promyelocytic leukemia(APL), based on this facts, studies have been carried out to study its role in the treatment of solid cancer at home and abroad. Primary in vitro study showed that As2O3 could treat the cancer of digestive system such as hepatoma, esophageal carcinoma, gastric cancer, and the cancer of urinary and reproductive system such as cervical cancer, ovarian cancer, bladder transitional carcinoma,as well as lung cancer, breast cancer, prostate cancer, etc. The mechanism of As2O3 actions may be the induction of apoptosis, the inhibition of growth and the promotion of differentiation of solid cancers. This article reviews on As2O3 in treatment of solid cancer.

Cases of nasopharyngeal carcinoma receiving radiotherapy were treated by Sisheng Decoction which yielded marked antagonistic actions against the decrease of WBC and platelets.Thus,97.4% of the cases were able to successfully receive the whole course of radiotherapy.Animal experiment showed that the ac-tions of the Decoction was realized by regulating thecontents of ?—endorphine in the blood.
9.Effect of PRL on the expression of CD154 in Jurkat cells
Chinese Journal of Endocrinology and Metabolism 1985;0(01):-
Expression of PRL receptor mRNA in Jurkat D1.1 cell line was confirmed by RT PCR. CD154 expression of Jurkat cells was significantly increased when these cells were incubated with PHA and recombinant human PRL, suggesting that binding of PRL to its receptor promotes CD154 expression which plays a role in immune regulation.
10.Expression of PRLr mRNA in human immune system
Chinese Journal of Immunology 1999;0(12):-
Objective:To investigate the expression of prolactin receptor(PRLr) in human immune system.Methods:Specimens of human immune system were obtained from both central and peripheral immune organs, including thymus(thymoma), bone marrow, lymph node and peripheral blood mononuclear cells. Specific fragments of PRLr mRNA were obtained through RNA isolation and RT-PCR amplification and confirmed by DNA sequencing.Results:PRLr mRNA was detected from the thymoma, bone marrow, lymph node and peripheral blood mononuclear cells. All the PRLr cDNA fragments generated by PCR were as long as the expected length, which was 276 bp. The sequencing result of the cDNA was identical to the sequence of PRLr cDNA in GeneBank.Conclusion:The study confirmed that prolactin receptor mRNA was expressed in human central immune organs such as thymus and bone marrow and peripheral immune organs such as lymph node and peripheral blood mononuclear cells. This phenomenon provided a biologic structural evidence that neuro-endocrine hormone PRL might play a modulating role on immune cells from receptor's point of view.
