ABSTRACT

【Objective】 To explore the methods and safety of autologous peripheral hematopoietic stem cells collection in patients with sequential double transplantation of solid tumors and conduct efficacy analysis. 【Methods】 Peripheral blood stem cells were collected from 27 patients with solid tumors after routine mobilization of rhG-CSF and rhGM-CSF.A specific program was made for the patients.The condition and cooperation degree of children were comprehensively evaluated before cell collection, and a femoral venous catheterization was inserted to ensure the cells collected smoothly.A mononuclear cell collection(MNC) program was selected, and machine parameters were set based on the patient's low body weight.The number of mononuclear cell (MNC) and the CD34+ cell was detected by flow cytometry for retrospective analysis. 【Results】 A total of 73 cell collections were performed in 27 patients, and the number of mononuclear cells and CD34+ cells was 12.586(10.22~19.586)×108/kg and 13.575(7.275~23.825)×106/kg, respectively, which can meet the requirement of sequential double transplantation. No intoxication of citrate and other serious adverse reactions occurred, and the follow-up was generally in good condition. 【Conclusion】 The method is effective and safe for pediatric patients, even for pediatric patients with low weight. Sufficient stem cells can be collected for patients with solid tumors by this method to meet the requirement of sequential double transplantation.

ABSTRACT

Objective:To study the effect of atractylodes lactideⅠ,Ⅱand Ⅲ on the expression of cytokines by inducing M1 type macrophage model. Methods:Apoptotic macrophages were induced by sodium thioglycolate, and then the rat peritoneal inflammatory macrophages were purified by a differential adherence method. The expression of macrophage marker antigen (ED1) was identified by flow cytometry macrophages. Tumor necrosis factor ( TNF-α) , proinflammatory cytokines ( IL-1β) and interleukin-6 ( IL-6 ) were measured by ELISA in vitro. The levels of expression of arginase 1, inducible nitric oxide synthase (iNOS), inflammatory cytokines (IL-1β) chemokine (CCL22) and transforming growth factor (TGF-β) in inflammatory macrophages were determined by RT-PCR. Results:As for the purification of cultured rat inflammatory macrophage expressing ED1, atractylenolideⅠand Ⅲ could reduce the ex-pression levels of iNOS and IL-1βand increase the expression levels of arginase1 CCL22 and TGF-β. The release of inflammatory fac-tor IL-1β decreased, and the release levels of TGF-β and chemokines CCL22 were promoted(P<0. 05). Atropine lactoneⅠ and Ⅲ had significant inhibitory effects on TNF-α, IL-1β and IL-6 in macrophages(P<0. 05). Conclusion: Atractylodes lactone Ⅰand Ⅲ with anti-inflammatory activity can promote the expression of cytokines in inflammatory macrophages, while the change induced by at-ractylaxanthin Ⅱ is not obvious.

ABSTRACT

@#ObjectiveTo assess the value of spinal ultrasound in children with congenital anomalies of spine. MethodsUltrasound findings of 36 children with congenital anomalies of spine were analyzed and compared with the finding of corresponding MRI or operation. ResultsUltrasound finding was the same as MRI in the anatomy in 31/36 children, in addition, it also could show the pulsatile motion and blood flow signals of conus medullaris. ConclusionSpinal ultrasound can present more other informations for diagnosis for congenital anomalies of spine, especially the blood supply of conus medullaris.

ABSTRACT

@#Objective To evaluate the value of color Doppler ultrasonography for diagnosis of superior mesenteric artery diseases. Methods78 patients with abdominal pain suspected to be superior mesenteric artery diseases underwent color Doppler ultrasonography. The results were compared with other imaging methods or findings in operation. Results4 patients with superior mesenteric artery embolization coincided with the founding in operation. 18 of the 22 patients suggested with superior mesenteric artery stenoses were confirmed by CTA or DSA. ConclusionColor Doppler ultrasonography can be used in diagnosis of superior mesenteric artery diseases.
