To cultivate nursing students with international professional ability for higher vocational education is the key to promote the internationalization of Chinese nursing field. Through analyzing the de-veloping trends and problems of international nursing education in China, based on the international nurses' ability, and study from the nurses training model of Philippines, the international nursing training model was constructed. The paper discussed the selection and retention of students, emphasizing the cultivation of students' international nursing concept and professional English, focusing on the ISPN curriculum and the integration of theory and practice, encouraging the cooperation of international school and faculties sharing, adapting the students-centered teaching methods, and establishing a corresponding sound evaluation system.

Insulin resistance (IR) is a complex metabolic disorder related to several diseases including type 2 diabetes (T2DM), hypertension and dyslipidemia. These diseases are all independent risk factors for cardiovascular disease. Lipid metabolism disorder has toxic effects on cells and may cause or aggravate IR in performance of elevated plasma levels of triglyceride (TG) and free fatty acids (FFA), the last one is an independent risk factor for IR. It has been clear that FFA may induce IR by endoplasmic reticulum (ER) stress, oxidative stress, apoptosis and inflammation, although the specific mechanisms remained unknown. The present paper summarizes the related molecules involved in the pathogenic process of IR and its mechanism, might provide a theoretical basis for the molecular mechanism of IR caused by FFA, and therapeutic reference for clinical treatment of IR and prevention of T2DM.

OBJECTIVETo explore the genetics mechanism for the phenotypic variability in a patient carrying a rare ring chromosome 9.

METHODSThe karyotype of the patient was analyzed with cytogenetics method. Presence of sex chromosome was confirmed with fluorescence in situ hybridization. The SRY gene was subjected to PCR amplification and direct sequencing. Potential deletion and duplication were detected with array-based comparative genomic hybridization (array-CGH).

RESULTSThe karyotype of the patient has comprised 6 types of cell lines containing a ring chromosome 9. The SRY gene sequence was normal. By array-CGH, the patient has carried a hemizygous deletion at 9p24.3-p23 (174 201-9 721 761) encompassing 30 genes from Online Mendelian Inheritance in Man.

CONCLUSIONThe phenotypic variability of the 9p deletion syndrome in conjunct with ring chromosome 9 may be attributable to multiple factors including loss of chromosomal material, insufficient dosage of genes, instability of ring chromosome, and pattern of inheritance.

Objective:To analyze the reform of improving the teaching effects of nursing college students' practical training.Methods:Cluster sampling method was used to select 396 nursing college students in a higher nursing school as the research objects, with 197 in experimental group and 199 in control group. Self-directed learning was adopted in practical teaching of surgical nursing in the students in experimental group, and traditional surgery teaching was adopted in control group. Self-rating scale of self-directed learning (SRSSDL) was used every 3 months during the period. The students' self-directed learning ability was measured dynamically, and the scores of practical examination and course satisfaction were compared between the two groups. The data were statistically analyzed by repeated measures analysis of variance and independent sample t-test using SPSS 17.0.Results:The scores of repeated measurement of SRSSDL in the experimental group were higher than those in the control group ( F=16.237, P=0.016). Except for the common surgical instruments module ( P=0.056), the scores of practical training examination in the experimental group were higher than those in the control group, and the differences were statistically significant ( P<0.01 for the operating room nursing module, P=0.005 for the wound nursing module, P<0.01 for the enterostomy nursing module). The students' satisfaction with the overall curriculum in the experimental group was higher than that in the control group. Conclusion:Self-directed learning in the teaching of nursing practice can effectively enhance comprehensive ability and quality of students based on self-directed learning ability, and improve the teaching effect of practical training courses.

Objective:To discuss the expression of programmed cell death-ligand 1(PD-L1)in the oral squamous cell carcinoma(OSCC)cells and its effect on biological behavior of the OSCC CAL27 cells,and to clarify the possible mechanism.Methods:Western blotting method was used to detect the expression levels of PD-L1 protein in the oral epithelial HOK cells and OSCC CAL27,TCA8113,and SCC15 cells;immunofluorescence staining method was used to detect the expression and localization of PD-L1 protein in the CAL27 cells.The CAL27 cells were divided into control group(transfected with si-NC)and si-PD-L1 group(transfected with si-PD-L1).Western blotting method was used to detect the interference efficiency of the cells in two groups;CCK-8 assay was used to detect the proliferative activities of the cells in two groups at different time points;plate clone formation assay was used to detect the numbers of clone formation of the cells in two groups;cell scratch healing assay was used to detect the scratch healing rates of the cells in two groups;Transwell chamber assay was used to detect the numbers of migration and invasion cells in two groups.Results:The expression level of PD-L1 protein in the OSCC cells was higher than that in the HOK cells(P<0.05 or P<0.01);PD-L1 expressed in the cytoplasm and nucleus of the CAL27 cells.The CCK-8 assay and plate clone formation assay results showed that compared with control group,the proliferative activities of the CAL27 cells in si-PD-L1 group at different time points were significantly decreased(P<0.05 or P<0.01),and the numbers of clone formation were significantly decreased(P<0.01).The cell scratch healing assay results showed that compared with control group,the scratch healing rates of the cells in si-PD-L1 group were significantly decreased(P<0.05 or P<0.01).The Transwell chamber assay results showed that compared with control group,the numbers of migration and invasion cells in si-PD-L1 group were significantly decreased(P<0.01).Conclusion:The expression of PD-L1 in the OSCC cells is higher than that in normal oral epithelial cells,and knocking down PD-L1 expression can inhibit the proliferation,clone formation,migration and invasion capabilities of the OSCC cells.

OBJECTIVETo evaluate the antitumor efficacy of proliferating cell nuclear antigen antisense oligonucleotide (PCNA-ASO) in combination with recombinant adenovirus p53 (Ad-p53) against bladder cancer EJ and BIU-87 cells in vitro and in vivo.

METHODSCells were transfected with Ad-p53 (100 MOI), and PCNA-ASO (1.6 micro mol/L) was then introduced into the cells using a cationic lipid (lipofectamine, 20 micro l/ml). In vitro and in vivo antitumor effects of combining PCNA-ASO with Ad-p53 were measured using the MTT assay, flow cytometry, clone formation, and a nude mice model.

RESULTSThe combination of PCNA-ASO and Ad-p53 inhibited cell viability in both the EJ (89.3%) and BIU-87 (78.6%) cell lines. The ability of the cells to form foci was also reduced by 74.8% in EJ cells and by 67.5% in BIU-87 cells (P < 0.01). A significant decrease of cells in the S phase (11.4% in EJ cells, 14.6% in BIU-87 cells) and a significant increase of cells in G1 phase (62.2% in EJ, 56.8% in BIU-87) were noted. The mean tumor volume after 7 days of treatment with PCNA-ASO or Ad-p53 in combination decreased to 47.6% or 36.4% of the initial tumor size in the two cell lines respectively.

CONCLUSIONThese results indicate that combined PCNA-ASO and Ad-p53 in the treatment of bladder cancer with mutant p53 has important therapeutic potential, significantly suppressing the growth of human bladder cancer both in vitro and in vivo.

To evaluate the effects of adenovirus (Ad)-mediated transfer of p53 and p16 on human bladder cancer cells EJ, EJ were transfected with Ad-p53 and Ad-p16. Cell growth, morphological change, cell cycle, apoptosis were measured using MTT assay, flow cytometry, cloning formation, immunocytochemical assays. Ad-p16 or Ad-p53 alone could inhibit the proliferating activity of EJ cells in vitro. Ad-p53 could induce apoptosis of partial EJ cells. G1 arrest was observed 72 h after infection with Ad-p16, but apoptosis was not obvious. The transfer of Ad-p16 and Ad-p53 could significantly inhibit the growth of EJ cells, decrease the cloning formation rate and induce apoptosis of large number of EJ cells. The occurrence time of subcutaneous tumor was delayed and the tumor volume in 4 weeks was diminished by using Ad-p53 combined with Ad-p16 and the difference was significant compared with using Ad-p53 or Ad-p16 alone. It was suggested that the transfer of wild-type p53 and p16 could significantly inhibit the growth of human bladder cancer in vitro and in vivo.

OBJECTIVE: To carry out G-banded chromosomal karyotyping and chromosomal microarray analysis (CMA) for a fetus featuring multiple malformations. METHODS: The fetus was found to have increased nuchal thickness, generalized edema, asymmetric lower limbs, tetralogy of Fallot, nasal bone anomaly and cleft palate. Following amniocentesis, G-band karyotyping and CMA were carried out. RESULTS: The fetus had a karyotype of 47,XX,+i(12)(p10) [14]/46,XX[6]. CMA has identified a 33.9 Mb duplication at 12p13.33-p11.1, which was suggestive of tetrasomy 12p. CONCLUSION Combined chromosomal karyotyping and CMA can delineate the origin of abnormal chromosomal fragments during prenatal diagnosis. The fetus was diagnosed with Pallister-Killian syndrome.

Objective:To observe heart rate circadian rhythm in patients with chronic kidney disease (CKD) stage 5 and to analyze the effects of parathyroidectomy (PTX) on heart rate circadian rhythm in severe secondary hyperparathyroidism (SHPT) patients.Methods:A cross-sectional observation was performed in 213 patients with CKD stage 5 and 96 controls, and the patients were divided into those with severe SHPT (PTX group, n=70) and without severe SHPT (non-PTX group, n=143). Forty-six PTX patients were followed up prospectively. The baseline data were compared among these groups. Holter electrocardiogram was performed for each participant. Non-dipping heart rate was defined as night/day heart rate ratio greater than 0.9. Multiple linear regression analysis was used to analyze the related factors of heart rate circadian rhythm in patients with CKD stage 5. Results:The 24-hour, daytime and nighttime mean heart rate in patients with CKD stage 5 were all higher than those in controls, especially in PTX group (all P<0.05). The night/day heart rate ratios of controls and CKD stage 5 patients were (0.81±0.08) and (0.91±0.08) respectively ( P<0.01). Correlation analysis showed 24-hour and daytime or nighttime mean heart rate in patients with CKD stage 5 were positively correlated with serum levels of phosphorus and ln(alkaline phosphatase), while nighttime mean heart rate and night/day heart rate ratio were positively related with serum intact parathyroid hormone level. After adjusting with postoperative follow-up period (median time: 10.9 months), 24-hour and nighttime mean heart rate, and night/day heart rate ratio in PTX patients all decreased significantly (all P<0.01). Conclusions:Heart rate is increased and circadian rhythm is abnormal in patients with CKD stage 5, which are related with mineral and bone disorder. PTX significantly decreases 24-hour and nighttime mean heart rate in severe SHPT patients, and improves the heart rate circadian rhythm.
