Objective:To explicit phenylephrine (PE), α1-adrenergic receptor (α1-AR) on myocardial fibrosis regulation and interleukin-1 (IL-1), IL-6, tumor necrosis factor-α (TNF-α) expressions in pressure overloaded mice.
Methods:A total of 49 KM mice were randomly divided into 3 groups: Blank control group, n=7, Sham operation group, n=7, Transverse abdominal aortic constriction (TAC) group, n=35, and 8 weeks later, the mice in TAC group were further divided into 5 sub-groups as TAC control, TAC+PE, TAC+Praz, TAC+Prop, TAC+Carv sub-groups, n=5 in each sub-group, and the animals were respectively treated for 3 weeks. Left ventricular collagen volume fraction (CVE), hydroxyproline content and IL-1, IL-6, TNF-α expressions were examined respectively.
Results: By 8 weeks treatment, compared with Blank control group, TAC group had obvious myocardial fibrosis, increased hydroxyproline content and IL-1, IL-6, TNF-α expressions,P<0.001. Compared with TAC control sub-group, TAC+PE, AC+Prop, TAC+Carv sub-groups showed decreased CVF, hydroxyproline content and IL-1, IL-6, TNF-αexpressions,P<0.001, while the above changes were not obvious in TAC+Praz sub-group,P>0.05; CVE and hydroxyproline content were similar between TAC+PE and TAC+Prop sub-groups, while the expressions of IL-1, IL-6 and TNF-α were obviously decreased in TAC+Prop sub-group,P<0.05. Conclusion: PE may improve myocardial ifbrosis and IL-1, IL-6, TNF-α expressions by activating α1-AR in pressure overloaded mice, α1-AR might be a defending factor for myocardial ifbrosis.

Objective To investigate the risk factors for colorectal cancer adjuvant chemotherapy induced leucopenia. Methods The basic clinical data of 108 patients with colorectal cancer who had received radical operation and adjuvant chemotherapy were retrospectively evaluated. The patients were divided into two groups: normal white blood cell group (39 patients) and leucopenia group (69 patients). The data were analyzed with SPSS 22.0 software, t test, χ2 test , univariate analysis and multifactor Logistic regression analysis, and analysis of variance to investigate the risk factors for colorectal cancer adjuvant chemotherapy induced leucopenia. Results Univariate analysis revealed that the female patients and the ones who received radiotherapy were more prone to leucopenia (P<0.01), while hypertension, the levels of white blood cell, neutrophil counting and serum creatinine before chemotherapy were protective factors for leucopenia (P<0.05 or<0.01). Multifactor Logistic regression analysis revealed that the level of serum creatinine before chemotherapy was an independent risk factor for leucopenia, OR = 0.950 (95% CI: 0.906- 0.996, P<0.05). The further analysis showed the lower the level of serum creatinine, the more severe the leucopenia would be (P = 0.04). Conclusions The level of serum creatinine before chemotherapy was an independent risk factor for colorectal cancer adjuvant chemotherapy induced leucopenia.

ObjectiveTo discuss the application value of high frequency ultrasound (HFUS) characteristics, acoustic radiation force impulse (ARFI) imaging technology and contrast-enhanced ultrasound (CEUS) in the diagnosis of soft tissue hemangioma.MethodsTo retrospectively analyze the clinical data of 44 cases of soft tissue hemangioma that were treated in Capital Medical University Affiliate Beijing Chaoyang Hospital from August, 2013 to May, 2014, and to analyze the difference between the characteristics of HFUS, ARFI and CEUS in soft tissue hemangioma and normal surrounding tissue.ResultsHFUS shows the features of morphological diversity of sinus shape expansion tube structure, unclear boundary, irregular configuration, compressibility and partial strong echo in the phlebolith. Color Doppler ultrasound (CDFI), detects abundant interphase red-blue bloodstream signal slowly and consistently. The blood signal is strengthened after partial compression. CDFI shows more vein spectrum in the lesion. The discrepancy of comparison between VTQ and SWV value of soft tissue hemangioma and surrounding muscular tissue possesses statistical significance [(1.082±0.183) m/svs (1.414±0.331) m/s,P<0.01]. Ultrasound contrast can show the relationship between diseased region and surrounding tissue clearly, which is beneficial to the selection of operation method and prognosis.ConclusionThrough conventional two-dimensional ultrasound and high frequency CDFI, and further combining the acoustic pulse radiation ARFI technology and CEUS technology, the soft tissue hemangioma can’t only be more accurately diagnosed, but also provides more reliable diagnostic basis for clinic.
