ABSTRACTOBJECTIVE To study the optimum preparation condition of inclusion complexes of resveratrol by ultrasonic method.METHODS The inclusion complexes were prepared by ultrasonic method.The optimum preparation condition was studied by orthogonal test with encapsulation rate as the index of evaluation.RESULTS The optimum preparation conditionthe ratio of resveratrol toβ?CD is 1∶2inclusion temperature is 50℃ultrasonic time is 4 hoursultrasonic power was 300W. The inclusion of inclusion rate is 44.58%.CONCLUSION The inclusion complexes prepared by ultrasonic method have such advantagessimplicity of operatorcondition easily controledslightly affected by external influence.

PURPOSE: Vascular endothelial growth factor (VEGF) signal transduction mainly depends on its binding to VEGF receptor 2 (VEGFR-2). VEGF downstream signaling proteins mediate several of its effects in cancer progression, including those on tumor growth, metastasis, and blood vessel formation. The activation of VEGFR-2 signaling is a hallmark of and is considered a therapeutic target for breast cancer. Here, we report a study of the regulation of the VEGFR-2 signaling pathway by a small molecule, isomangiferin. METHODS: A human breast cancer xenograft mouse model was used to investigate the efficacy of isomangiferin in vivo. The inhibitory effect of isomangiferin on breast cancer cells and the underlying mechanism were examined in vitro. RESULTS: Isomangiferin suppressed tumor growth in xenografts. In vitro, isomangiferin treatment inhibited cancer cell proliferation, migration, invasion, and adhesion. The effect of isomangiferin on breast cancer growth was well coordinated with its suppression of angiogenesis. A rat aortic ring assay revealed that isomangiferin significantly inhibited blood vessel formation during VEGF-induced microvessel sprouting. Furthermore, isomangiferin treatment inhibited VEGF-induced proliferation of human umbilical vein endothelial cells and the formation of capillary-like structures. Mechanistically, isomangiferin induced caspase-dependent apoptosis of breast cancer cells. Furthermore, VEGF-induced activation of the VEGFR-2 kinase pathway was down-regulated by isomangiferin. CONCLUSION: Our findings demonstrate that isomangiferin exerts anti-breast cancer effects via the functional inhibition of VEGFR-2. Pharmaceutically targeting VEGFR-2 by isomangiferin could be an effective therapeutic strategy for breast cancer.

Objective To investigate the effects of gemstone energy spectrum CT atomic number method and infrared spec-troscopy for analyzing the composition of urinary calculi and to compare their values in qualitative diagnosis of urinary calculi .Meth-ods Two hundreds and sixty cases of urinary tract stones were performed the gemstone spectrum CT urinary scanning and the stone composition was identified by atomic number method .After removing stone ,the stone composition analyzed by infrared spec-troscopy served as the gold standard .Then the consistency identified by the two methods was analyzed .Results The Kappa consis-tency test results showed that the two kinds of method for identifying stone type had good consistency (Kappa=0 .787 ,P<0 .01) . The paired chi square test results showed that the difference of the two methods for identifying the stone type had no statistical sig-nificance(χ2 =6 .581 ,P=0 .254) .The stone crystal composition types measured by gemstone energy spectrum CT atomic number method were less than those measured by infrared spectroscopy .The precise quantification of the stones with different crystal struc-tures was not as accurate as that of infrared spectroscopy (calcium oxalate monohydrate and calcium oxalate dihydrate ) .Conclusion The two methods for analyzing theurinary stone composition all have clinical significance ,the stone analysis method should be se-lected according to the actual situation .

Objective:To explore the effect of "WeChat official account"+multidisciplinary team (MDT) cooperative nursing in discharged patients with cerebral infarction.Methods:From January 2019 to December 2020, 118 discharged patients with cerebral infarction were selected by convenience sampling from Qingdao Hospital affiliated to Shandong First Medical University as the research object. The patients admitted from January to December 2019 were taken as the control group, and the patients admitted from January to December 2020 were taken as the observation group, with 59 cases each. The control group was given routine intervention and follow-up after discharge. The observation group received "WeChat official account"+ MDT cooperative nursing on the basis of the control group. Both groups were intervened for three months. The Stroke Behavior Change Questionnaire, Fugl-Meyer Assessment (FMA) , Self-Rating Anxiety Scale (SAS) , Self-Rating Depression Scale (SDS) , compliance and adverse events of the two groups were compared before and after the intervention.Results:Before the intervention, there was no statistical difference between the two groups in the scores of Stroke Behavior Change Questionnaire, FMA, SDS and SAS ( P>0.05) . After the intervention, the scores of Stroke Behavior Change Questionnaire and FMA in the observation group were higher than those before the intervention and the control group, and the SDS and SAS scores were lower than those before the intervention and the control group, with statistical differences ( P<0.01) . The treatment compliance of the observation group was 94.92% (56/59) , higher than 81.36% (48/59) of the control group, with a statistical difference ( P<0.05) . Conclusions:"WeChat official account" + MDT cooperative nursing can effectively improve the exercise behavior of discharged cerebral infarction patients, increase compliance, promote neurological recovery, alleviate negative emotions, and reduce the incidence of adverse events after discharge, which is worthy of clinical practice.
