Objective To study the effect of nicotine on the expression of αvβ3 integrin in cultured neonatal bovine cerebral microvascular endothelial cells (BCMEC). Methods Flow cytometry was utilized to determine the cell ratio of in vitro cultured neonatal BCMECs adhesive to rat monocytes (MN), after the former were treated with nicotine prior to the incubation with MNs. The effect of niocotine on αvβ3 expression in BCMEC was observed with ELISA. Results In response to 10-5 mol/L ni cotine pretreatment, the adhesive cell ratio of BCMECs to MNs was increased (P<0.05) and enhanced αvβ3 expression was observed, in comparison with those when nicotine of lower concentrations were administered. In contrast, more obvious increase in the adhesive cell ratio and αvβ3 expression was observed when the pretreatment protocol with nicotine (10-7~10-5 mol/L) and IL-1β was adopted, and the effect of nicotine was concentration-dependent. The endothelial adhesion to MNs induced by nicotine and IL-β was obviously blocked by anti-αvβ3 integrin Ab. Conclusion Nicotine may increase the expression of αvβ3 integrin in BCMEC.

OBJECTIVE: A case of half sibling was determined with multiple genetic markers, which could be potentially applied for determination of half sibling relationship from same father. METHODS: Half sibling relationship was detected by 39 autosomal STR genetic markers, 23 Y-chromosomal STR genetic markers and 12 X -chromosomal STR genetic markers among ZHAO -1, ZHAO -2, ZHAO -3, ZHAO -4, and ZHAO-5. RESULTS: According to autosomal STR, Y-STR and X-STR genotyping results, it was determined that ZHAO-4 (alleged half sibling) was unrelated with ZHAO-1 and ZHAO-2; however, ZHAO-3 (alleged half sibling), ZHAO-5 (alleged half sibling) shared same genetic profile with ZHAO-1, and ZHAO-2 from same father. CONCLUSION It is reliable to use multiple genetic markers and family gene reconstruction to determine half sibling relationship from same father, but it is difficult to determination by calculating half sibling index with ITO and discriminant functions.

· Vascular endothelial growth factor is indispensable inducing factor in retinalangiogenesis. After the retinal neovascularization of proliferative diabetic retinopathy ( PDR ) patients, it can cause fibrovascular membrane formation, epiretinal membrane fibrosis increased, resulting in traction retinal detachment with further aggravate the condition. The recent research suggests that cytokines promote fibroblast proliferation, movement, adhesion, and secretion of extracellular matrix functions in the diabetic state of the environment changes to profibrogenic state, resulting in the accumulation and fibrosis of extracellular matrix. This paper reviewed the status quo of the correlation between vascular endothelial growth factor and fibrosis-related cytokine.

Objective:To promote evidence-based practice in the pre-chemotherapy nursing assessment among adult cancer patients.Methods:The Joanna Briggs Institute Practical Application of Clinical Evidence System and Getting Research into Practice audit tools were used. The project was conducted in Shanghai Cancer Center of Fudan University from May to October 2018, 12 audit criteria were developed in the program including nursing training, patient medical and allergic history, medical diagnosis, lab data and so on.Results:A baseline audit of pre-chemotherapy nursing assessment among adult cancer patients was conducted, with a sample size of 68 patients and 36 nursing staff, during this stage, the compliance of audit 11 and 12 were 100%. After the implementation of systematic strategies, a follow-up audit involving similar sample as first audit was conducted using the same audit criteria. In the follow-up audit, except criterion 4 and 10, the compliance of the remaining 8 criteria had significantly improved, and χ2 value was 10.29-132.06, P<0.01. The result of history adverse reaction in the follow-up audit showed that among 68 patients, 3 had experienced chemotherapy infusion reactions in the past (The drugs were oxaliplatin, gemcitabine and paclitaxel), 39 had chemotherapy-related symptoms before admission (most of them were relieved at admission), of which the top five were loss of appetite, fatigue, nausea, neurotoxicity and vomiting. Conclusions:The aims of the project were fulfilled. We achieved increased compliance with evidence-based best practice recommended by JBI in most of audit criteria. Further audit will need to be carried out to improve the validity and quality of nursing assessment.

Objective To investigate the relation between the cellular immune function and unexplained recurrent spontaneous abortion(URSA) and the mechanism of active immunotherapy on URSA patients.Methods The flow cytometry(FCM) was used to detect CD3+ ,CD4+ ,CD8+ T lymphocyte and CD16+CD56+ natural killer(NK) cell subsets and the ratio of CD4+/CD8+ of peripheral blood(PBL).112 cases with URSA(76 cases treated with active immunotherapy) and 30 cases of normal fertiled(NF) women were studied.The percentages of T lymphocyte and NK cell subsets before and after therapy were compared among 76 cases wtih URSA treated by active immunotherapy.The rate of next successful pregnancy of URSA patients treated with and without active immunotherapy was compared.Results The percentages of CD3+ and CD16+CD56+ cell subsets as well as the ratio of CD4+/CD8+ of the URSA patients were significantly higher than those of NF cases(P <0.05).After active immunotherapy,the percentages of CD3+ and CD56+CD16+ cell subsets as well as the ratio of CD4+/CD8+ of URSA cases were significantly decreased(P <0.05 ).The rate of next successful pregnancy of URSA cases with and without active immunotherapy were 88.2% and 31.2% respectively,the difference was significant(P< 0.05).Conclusion The changes in the percentages of T lympyocyte and NK cell subsets have something to do with URSA.Active immunotherapy can effectively regulate the cellular immune function and increase the rate of next successful pregnancy of URSA patients.

Objective:To observe influence of statins on antiplatelet activity of clopidogrel and provide basis for ra‐tionality of statins combined clopidogrel treatment .Methods :According to random number table ,a total of 90 pa‐tients diagnosed as acute coronary syndrome were equally divided into clopidogrel group ,clopidogrel + simvastatin group and clopidogrel + pravastatin group . Three groups received corresponding routine medication treatment . Plasma levels of platelet αgranule membrane protein (CD62P) ,lysosomal granule membrane glycoprotein (CD63) and maximum platelet aggregation rate (MPAR) were measured and compared among three groups before and 3d af‐ter treatment .Results:Compared with before treatment ,after treatment ,there were significant reductions in plas‐ma levels of CD62P and CD63 and MPAR in three groups , P<0.01 all .After treatment ,there were no significant difference in plasma levels of CD62P [ (14.63 ± 3.45) ng/ml vs .(14.14 ± 4.32) ng/ml vs .(14.59 ± 4.23) ng/ml] , CD63 [ (26.32 ± 10.43) ng/ml vs .(27.04 ± 10.75) ng/ml vs .(27.29 ± 9.27) ng/ml] and MPAR [ (28.62 ± 17.68)% vs .(28.38 ± 16.43)% vs .(29.13 ± 14.23)% ] among clopidogrel group ,clopidogrel + simvastatin group and clopidogrel + pravastatin group ,P>0.05 all .Conclusion:Short‐term and routine dose of statins combined clo‐pidogrel is feasible in treatment of acute coronary syndrome .The combined use of them will not affect antiplatelet function of clopidogrel .
