Objective To investigate (1) whether or not irbesartan can relieve endothelial dysfunction of essential hypertension; (2) which of fosinopril and irbesartan is better in relieving the endothelial dysfunction in essential hypertension, especially for the elderly . Methods Sixty-two elderly patients with essential hypertension were divided into two groups: fosinopril group and irbesartan group. After 3 months treatment, the effect of drugs on BP and the endothelium-dependent relaxation(EDR) of brachial artery (BA) with high resolution ultrasound examination were analyzed, meanwhile the plasma levels of NO、ET-1 and vWF were assessed. Results Fosinopril and irbesartan groups had a similar (P

Objective To investigate nurses′ learning motivation and learning satisfaction with continued education and analyze its influencing factors. Method One hundred and seventy-nine nurses were enrolled in the survey and the general information questionnaire, education participation scale and continuing education learning satisfaction scale were used in the investigation. Results The average score by nursing education participation scale was (3.26 ± 0.59), and that of continuing education learning satisfaction scale was (2.74 ± 0.48). There were statistically significant differences in age, length of employment, professional title, marital status, employment mode between the scores by the two scales (P < 0.01). Conclusions Nurses′ learning motivation and learning satisfaction with continuing education are in the medium level. Pertinent guidance such as bringing continuing education in depth and width is suggested to improve satisfaction and motivations of nurses.

Objective To report three-year-old twin brothers with speech stunting.Methods The clinical program of twin brothers with speech stunting were reported.Results The development quotient of Neuropsychological Developing Table of 0 to 6 Years-Old Nurselings was 59 for elder brother,and 57 for the younger.PET showed hypogenesis in the frontal lobe.Their linguistic rating showed both speech stunting,and the brain-audition evoked potential and the autistic evaluation(ABC and CARs)were normal.Conclusion The etiology of twin brothers' speech developing disorders is related with heredity,brain development,and speech environment,but the exact cause is being further studied.

Objective To investigate the interactions between melanoma-derived exosomes and the microenvironment.Methods The exosomes were isolated from the culture medium of mouse melanoma cells and then co-cuhured with mesenchymal stromal cells (MSC) after identification.Immunofluorescence assay was performed to observe the exosomes engulfed by MSC.CCK-8 and transwell assays were used to evaluate the proliferation and migration of MSC.Effects of the exosomes on the expression of α-smooth muscle actin (α-SMA) in MSC were analyzed by Western blot.Results Co-culture of MSC with melanoma cell-derived exosomes enhanced the proliferation and migration of MSC as well as the expression of α-SMA.All of the changes mediated by the exosomes could be blocked by using the inhibitor of TGF-β receptor.Conclusion Melanoma cell-derived exosomes enhanced the proliferation and migration of MSC as well as the expression of α-SMA through TGF-β signaling pathway,which provided an advantageous microenvironment for melanoma progression.

Hyaluronic acid(HA)is a linear polysaccharide chain composed of alternating ?-1,4-glucuronic acid(GlcA)and ?-1,3-N-acetylglucosamine(GlcNAc)moieties.Construction of engineering strain has become the prevailing strategy for increasing yield and improving its quality,especially the molecular weight.Here the molecular mechanism of HA biosynthesis in Streptococcus strains was reviewed,involving fermentation strains,operon structure,crucial enzyme and construction of engineering strains.In addition,the prevalent problems in HA fermentation production were also discussed and the protocols were tentatively put forward for the upcoming research and industrial production.

Peking University Shenzhen Hospital launched a reform to outsource its logistic support service to overcome the setbacks of overstaffing,poor service and high costs with the existing logistic departments since its opening.Practice of a decade has raised the quality of its logistic support system and lowered service costs.Furthermore,the reform has optimized the hospital's human resource structure,and improved performance of the hospital staff,paving the way for better social benefits of the hospital.
