BACKGROUND:Neuroblastoma is a common solid tumor in children. Pediatric tumors are little affected by environmental factors, but closely related to child development. The suspension method is an effective and reliable method to harvest neoplastic stem cel s.
OBJECTIVE:To culture the cel clones of human neuroblastoma cel line SK-N-SH and to assess the biological properties of the cel clones.
METHODS:Using the suspension method with no serum media, tumor cel clones were obtained. Immunofluorescence method was used to identify whether tumor cel clones exhibit stem cel properties. SK-N-SH neuroblastoma was labeled by luciferase, and tumor cel clones and tumor cel s were seeded onto the back of nude mice to monitor cel proliferative properties in nude mice using in vivo imaging.
RESULTS AND CONCLUSION:Using the suspension culture method, SK-N-SH neuroblastoma cel s could successful y develop into cloning bal s. Under serum-free culture, cloning bal s were immunofluorescently used to detect molecular markers that showed strong positive expression. Cloning bal s subcutaneously implanted into
nude mice showed the strong ability of self-renewal and differentiation as stem cel s. The cel clones cultured by the suspension method strongly expressed Nestin, but weakly expressed glial fibril ary acidic protein, neuron-specific tubulin, possessing stem cel characteristics and strong proliferation and metastasis in nude mice.

Objective To evaluate the clinical outcome of the method of repairing donor site of foot after improved toe-to-thumb reconstruction utilizing superficial circumflex iliac artery perforator (SCIAP) chimeric flap.Methods Fourteen cases of thumb defect were recruited from April,2012 to January,2016.According to Gu Yudong's classification,5 cases met the criterion of type Ⅰ,4 cases met the criterion of type Ⅱ,and 5 cases met the criterion of type Ⅲ.For type Ⅰ,the thumb was reconstructed with the great toe wrap-around flap.For type Ⅱ and Ⅲ,the thumb was reconstructed by the combined tissue with mutual artery (great toe wrap-around flap,and the bonetendon tissue of the second toe).All the donor sites of foot were repaired utilizing SCIAP chimeric flap.Results All the reconstructed thumbs survived.Among 14 free flaps of donor site,1 case suffered venous crisis and survived after exploration and rescue surgery.Dorsal skin necrosis of the second toe was found in 1 case,which was healed by local skin flap transposition.All patients were followed-up ranged from 3 to 30 months (averaged at 16 months).In spite of slightly bloated,the color and texture of all the flaps' was satisfied,and the average healing time of the bone in the donor sites was 2.5 months.All patients did not feel painful and had no adverse effect when walking and running.Three months after the operation,5 slightly bloated flaps in the donor sites under went flap plastic and achieved better appearance.On the part of iliaca,there was only one inconspicuous linear scar without any discomfort.Conclusion Repairing donor site of foot after improved toe-to-thumb reconstruction utilizing SCIAP chimeric flap was an ideal method.Using this method,the reconstructed thumb can achieve good appearance and function,all the toes of donor site were reserved,and the disability of the donor site is minimized.

OBJECTIVEIn order to find out the current situation of wild and cultivated resources of Glycyrrhiza uralensis, at the same time, the contents of glycyrrhizic acid and liquiritin were detected by HPLC.

METHODField investigation was carried out, and chemical composition of collected underground part was analyzed in laboratory.

RESULTThe natural distribution range of wild G. uralensis in China has no significant change. We can still find its distribution in the distribution areas recorded ten years ago, but the intensity of species group has greatly changed. Estimated according to the survey data obtained by quadrat reserves and distribution (i.e., reserves per unit area) or cultivation area, that the current wild reserves is less than 500,000 tons and the less than 150,000 tons for cultivated. The analysis results of glycyrrhizic acid and liquiritin contents in 99 wild samples of collected underground part show that the average contents of glycyrrhizic acid and liquiritin were respectively 34.8, 17.3 mg x g(-1), of which 61.6% samples can reach the standard (not less than 20, 10 mg x g(-1)) marked by "Chinese Pharmacopoeia" (2005 edition); The average glycyrrhizic acid and liquiritin contents of cultivated samples were respectively 28.5, 15.3 mg x g(-1), which were much lower than the wild samples.

CONCLUSIONWe should enhance efforts in protecting the wild resources, strive to improve the quality of cultivated herbs, vigorously develop high-quality G. uralensis cultivation industries and promote farmers income to resolve the resource crisis, which is the reasonable way to achieve continuable use of G. uralensis resources.
