ABSTRACT
Objective@#To explore the relationship between family cohesion, psychological resilience and non-suicidal self-injury among middle school students.@*Methods@#By using the stratified random cluster sampling method, 2 065 students from 4 middle school from Fujian province were investigated with family cohesion scale, adolescent psychological resilience scale and adolescent self-injury behavior questionnaire.@*Results@#The report rate of self-injury was 40.34%, which differed by childhood migration experiences, parenting style as well as academic pressure (χ2=11.66，29.45，12.48，P<0.01). Total scores and dimensional scales in family cohesion and psychological resilience showed significant differences in students with or without self-injury (t=-8.33，-12.08，-7.29，-11.53，-3.38，-7.37，-7.68，P<0.01). The family cohesion was positively correlated with the psychological resilience and each dimension (r=0.27-0.56, P<0.01), but negatively correlated with non-suicidal self-injury (r=-0.18, P<0.01). The psychological resilience and each dimension were negatively correlated with non-suicidal self-injury (r=-0.24--0.14, P<0.01). Psychological resilience had a partial mediating effect between family cohesion and non-suicidal self-injury, with mediating effect accounting for 61.11% of the total effect.@*Conclusion@#Psychological resilience played a mediating role between family cohesion and non-suicidal self-injury. By promoting family cohesion to improve psychological resilience, it is helpful to prevent non-suicidal self-injury among middle school students.
ABSTRACT
Objective To explore the interaction between warfarin and antiepileptic drugs such as carbamazepine and oxcarbazepine.Methods A 78-year-old woman suffered from warfarin resistance after initial warfarin dosing for several days.Based on her medication review,clinical pharmacist found that the warfarin resistance resulted from co-administered carbamazepine.Her warfarin dosage was increased,and the international normalized ratio (INR) increased to the target range.Another woman had been taking warfarin therapy for long time with a stable maintenance dose.She consulted clinical pharmacist for the influence of co-administered oxcarbazepine on warfarin.The patient was advised to maintain the dose and monitor her INR more closely.Her INR did not fluctuate.Results Carbamazepine induced warfarin metabolism.As a result,the patient needed increased dosage of warfarin to maintain the INR in the therapeutic target range.Oxcarbazepine does not induce liver enzymes,and therefore the INR did not fluctuate.Conclusion Carbamazepine may reduce the efficacy of warfarin.Oxcarbazepine offers a clinical advantage over carbamazepine,especially when co-administration of warfarin is required.
ABSTRACT
Objective To investigate the effect of down-regulation of lysine specific demethylase 1 (LSD1) by shRNA on the apoptosis and cell cycle of human acute myelogenous leukemia cells.Methods The lentiviral vector-mediated LSD1-shRNA was transfected into human acute promyelocytic leukemia HL-60 cells and acute monocytic leukemia SHI-1 cells.The expressions of LSD1 mRNA and protein were examined by real time quantitative PCR and Western blot,respectively.The flow cytometry was applied to detect the apoptosis and cell cycle distribution after AnnexinV-PE/7-AAD and PI dying,respectively.Results The expressions of LSD1 mRNA and protein in HL-60 and SHI-1 LSD1-shRNA group were significantly decreased compared with the blank control group and the negative shRNA group (P ＜ 0.01,respectively).The apoptosis levels of HL-60 and SHI-1 cells were significantly increased after knockdown of LSD1 (P ＜ 0.01).Moreover,the cell cycle distribution in the G0/G1 phases was also significantly increased(P ＜ 0.01).Conclusion LSDI-shRNA promotes cell apoptosis and increases the percentage of cells in the G0/G1 phases of human acute myelogenous leukemia cells.
ABSTRACT
In the process of MPH graduates education in medical universities , there are three problems such as lack of initiative subjective of postgraduate, uneven level of tutors and monitoring defi-ciency of education. The main reasons are the low quality of MPH graduates, lack of quality consciousness for graduates education and graduates’ value tending to be utilitarian. Facing the problems, we suggest establishing guarantee mechanism for MPH graduate education quality, strengthening the tutors’ construc-tion and framing an eliminating system.
ABSTRACT

Result In terms of the motor function of the lower extremities and the activity of daily living,the experiment group was superior to the control group(P<0.001).Conclusion The function training of bilateral limbs can promote the function rehabilitation of extremities of stroke patients with hemiplegia and improve the activities of daily living.
ABSTRACT
Objective To evaluate the impact of the hypoxia induced by bevacizumab on the antitumor effect in combining with irradiation in CNI-H441 xenografts in mice. Methods Bevacizumab of 5 mg/kg mouse for groups of control, bevacizumab alone, irradiation alone, earlier combination (EC), and later combination (LC) were initially injected peritoneally. Single irradiation of 14 Gy (122Sc γ-ray) was given at the 4th hour for the group of irradiation alone, 24th hour for EC group, and 72nd hour for LC group after the initial injection. Tumor hypoxia, micro vessels density and permeability of tumor vasculature,pathological responses, apoptosis, and tumor growth delay curve were evaluated after using bevacizumab and/or irradiation. Results Although it was lower than the control at the 24 hr after using bevacizumab (3. 1 × 106: 6.1 × 106 ;t = - 1.73 ,P > 0. 05), the HIF-1α rapidly increased to 3 - 4 times and 2 - 3 times of the control at day 3 (7.4 × 106: 20. 4 × 106; t = 2. 36, P < 0. 05) and lasted until day 10, which was consistent with the changes of tumor function vessels count. The count of residual micro vessel density count in LC group was higher than that in groups of EC and irradiation at day 3 after irradiation (9. 33: 3. 17;t =- 2. 43, P < 0. 05). The apoptotic count of tumor cells was lower in LC group than that in EC group (23.33: 43.83; t= 2.54, P< 0.05, at day 3 after radiation). Tumor growth delay time of LC groupwas shorter than that of EC groups (10. 5 days vs. 23. 0 days , t = 2. 67 , P < 0. 05) . Conclusions Hypoxia level induced by bevacizumab decreases the antitumor effect in later combination of bevacizumab and irradiaion. It shows a time window that determines whether the combination of bevacizumab and irradiation will be benefit or diverse.
