Practical Oncology Journal 2017;31(2):170-174
Endocrine therapy is one of the important treatments of adjuvant therapy among patients with positive hormone receptor breast cancer.In the endocrine therapy setting,5 years of tamoxifen therapy has been the standard treatment regimen for premenopausal patients.In recent years,this standard has been challenged.The results of many large randomized clinical trials have made a new choice for adjuvant endocrine therapy in premenopausal patients.In this paper,we review the present situation of endocrine therapy in premenopausal patients with positive hormone receptor breast cancer.

Chinese Mental Health Journal 1989;0(03):-
Objective : To revise the general self-efficacy scale. Methods : 3094 subjects from 7 different cities in China finished the general self-efficacy scale. Results : The result of Item Analysis showed that 19 of the scale met psychometric criteria. The scale's internal consistency was 0.81, split reliability 0.81. It had acceptable discriminant validity: subjects with higher scale scores also had significantly higher scores in every items than those with lower scale scores, and this scale could effectively differentiate the high and low level managers, it also could effectively differentiate the managers groug and workers group. Exploratory factor analyses indicated that the scale had one dominant factor. Conclusion : The general self-efficacy scale has sound psychometric properties for further research.

Journal of Medical Postgraduates 2004;0(01):-
Cerebral ischemia and reperfusion can cause delayed neuronal death in rodents,such as Mongolian gerbils and stroke-prone spontaneously hypertensive rats(SHRSP),which are used as an experimental stroke model.The protective effects of antioxidant nutrients such as vitamin E,green tea extract,ginkgo biloba extract,resveratrol,niacin and isoflavones in cerebral ischemia and reperfusion brain injury were reviewed.
8.The influence of silencing miRNA-155 on proliferation and apoptosis of human cutaneous squamous cell carcinoma cell line A431
Tianjin Medical Journal 2017;45(9):902-906
Objective To investigate the effects of antisense oligonucleotide against miRNA-155 (AS-miRNA-155) on proliferation,apoptosis and invasion and migration abilities of human cutaneous squamous cell carcinoma cell line A431. Methods AS-miRNA-155 was transfected into human cutaneous squamous cell carcinoma A431 cells by using LipofectamineTM 2000. Blank control without transfection and transfected with non-sense sequence were used as non-sense sequence control. Quantitative real-time polymerase chain reaction (qRT-PCR) was performed to detect the expression of miRNA-155 in A431 cells. Cell proliferation was analyzed using dimethyl thiazolyldiphenyl tetrazolium (MTT) assay. Cell cycle arrest and apoptosis were studied by flow cytometry (FCM). Invasion and migration were measured by Transwell chamber assays. Results The relative expression of miRNA-155 mRNA was lower in the transfection group than that in the blank control group and the negative control group (F=634.57, P<0.01), but there was no significant difference between the blank control group and the negative control group. After 72 h transfection, the survival rate was significantly lower in the transfection group than that of the blank control group and the negative control group, and the transfection rate decreased significantly by 120 h (P<0.05). Cells of G0/G1 phase increased, Cells of S phase reduced, the overall PI value decreased in transfection group, and the apoptosis rate of A431 cells, migration and invasion of cells increased (P<0.05). There was no significant difference in G2/M cycle between transfection group, blank control group and negative control group. There were no significant differences in A431 cell apoptosis rate, cell migration and invasive ability between blank control group and negative control group. Conclusion Antisense oligonucleotide against miRNA-155 can inhibit the expression of miRNA-155, the proliferation and promote the apoptosis of human cutaneous squamous cell carcinoma A431 cells, which indicates that miRNA-155 may become a new target for the regulation of gene expression in cutaneous squamous cell carcinoma.

10.Clinical Observation of Pidotimod Combined with Montelukast Sodium in the Treatment of Children with Bronchial Asthma
China Pharmacy 2016;27(29):4142-4144
OBJECTIVE:To observe clinical efficacy and safety of pidotimod combined with montelukast sodium in the treat-ment of children with bronchial asthma. METHODS:120 children with bronchial asthma were randomly divided into control group and observation group,with 60 cases in each group. Both group were given routine treatment as aerosol inhalation of glucocorticoid and anti-infective treatment. Control group was additionally given Montelukast sodium chewable tablet 5 mg orally,qd,at bed-time;observation group was additionally given Pidotimod capsule 0.4 g,qd,on the basis of control group. Both group received treatment for consecutive 3 months. Clinical efficacies of 2 groups were observed as well as IL-4,IFN-γ,IgE,T lymphocyte sub-set and lung function indexes of 2 groups before and after treatment. The occurrence of ADR were compared between 2 groups. RE-SULTS:The effective rate of observation group was 88.3%,which was significantly higher than that of control group (61.7%). There was no statistical significance in IL-4,IFN-γ,IgE,T lymphocyte subset and lung function indexes between 2 groups before treatment(P>0.05). After treatment,IL-4,IFN-γ,IgE,CD4+,CD4+/CD8+ and lung function of 2 groups were improved signifi-cantly,and the observation group was significantly better than the control group,with statistical significance(P<0.05). There was no statistical significance in the incidence of ADR between 2 groups(P>0.05). CONCLUSIONS:Pidotimod combined with monte-lukast sodium is effective for children with bronchial asthma,and can significantly relieve airway inflammation,enhance immunity and improve lung function with good safety.
