Objective To investigate the clinical application value of 18F-FDG PET-CT simulation localization in radiotherapy of recurrent abdominal and pelvic tumors. Methods 18F-FDG PET-CT was used to simulate positioning 38 patients with abdominal and pelvic tumors who relapsed after treatment.Based on both CT images and 18F-FDG PRT-CT, we drew up a systemic treatment plan and outlined the radiotherapy target area, and then compared the differences between the two methods. Results In 38 patients, 21.1%(3/8) of patients were found to have distal metastases outside the pelvic and abdominal cavity, and changed the systemic treatment plan.The radiotherapy target was altered in 34(89.5%) patients.The mean value of GTVPET-CT was 118.14cm3and the mean value of GTVCT was 148.53cm3(

[Objective]To explore the traditional processing techniques and Jingbang(Beijing local)experience of Ophiopogon japonicus,providing a reference for modern research on Opehiopogon japonicus.[Methods]Collecting data on the processing of Ophiopogon japonicus from ancient herbal literature and traditional Jingbang heritage materials,and consulting with old pharmacists,based on the analysis and organization,the various processing methods of Ophiopogon japonicus were restored.[Results]The purification methods of Ophiopogon japonicus have mechanisms such as removing the pith to relieve annoyance,removing the pith to treat channel dryness,and removing the pith to nourish lung Yin,with the first one being the most widely spread.The methods of removing the pith include boiling water to moisten the pith,clear water to moisten the pith,and roasting to soften the pith,with the first one being the most effective.The purpose of the wine soaking method is to alleviate the side effects of long-term use of Ophiopogon japonicus on stomach cold.The rice frying method should spread the rice thinly in the pot,spread Ophiopogon japonicus on the rice,and should not be stirred.If it is stirred with the rice,Ophiopogon japonicus is easy to puff up.The steaming method has two types:clear steaming and mixing with milk steaming.Ophiopogon japonicus is not easy to crush,and the intermittent roasting method recorded in Compendium of Materia Medica is very good.The method of simmering Ophiopogon japonicus and making Ophiopogon pills both utilize its juice-containing characteristics.The traditional Jingbang Ophiopogon japonicus has obvious local characteristics in the methods of moistening and removing the pith.Zhu Ophiopogon japonicus is for sprinkling water and moistening slightly,and cinnabar fine powder is finely scattered with sprinkling and stirring.These two processed varieties have disappeared for half a century.[Conclusion]The restoration and optimization of the processing methods of Ophiopogon japonicus are expected to improve the efficacy of Ophiopogon japonicus,providing higher quality Ophiopogon japonicus medicinal materials for the clinic.It reveals the local characteristics of the traditional Jingbang Ophiopogon japonicus processing,providing a possibility for the revival of the disappeared processed varieties,which is of great significance for enriching Chinese medicine resources and enhancing the clinical application value of Chinese medicine.

Tumor-associated macrophages (TAMs) mostly exhibit M2-like (alternatively activated) properties and play positive roles in angiogenesis and tumorigenesis. Vascular endothelial growth factor (VEGF) is a key angiogenic factor. During tumor development, TAMs secrete VEGF and other factors to promote angiogenesis; thus, anti-treatment against TAMs and VEGF can repress cancer development, which has been demonstrated in clinical trials and on an experimental level. In the present work, we show that miR-150 is an oncomir because of its promotional effect on VEGF. MiR-150 targets TAMs to up-regulate their secretion of VEGF in vitro. With the utilization of cell-derived vesicles, named microvesicles (MVs), we transferred antisense RNA targeted to miR-150 into mice and found that the neutralization of miR-150 down-regulates miR-150 and VEGF levels in vivo and attenuates angiogenesis. Therefore, we proposed the therapeutic potential of neutralizing miR-150 to treat cancer and demonstrated a novel, natural, microvesicle-based method for the transfer of nucleic acids.

Objective To discuss the clinical effect of horn perforator flaps for the treatment of finger soft tissue defect.Methods ① Lead oxide-gelatin mixture injection and CT scanning were performed in 4 fresh adult cadavers and the data was put into mimics 17.0 to achieve the three-dimensional reconstruction.The regulation and origins of the perforator vessel in proper palmar digital artery was observed.②From July 2012 to July 2015,9 cases with finger soft tissue defects were treated with horn perforator flaps.The defect areas ranged from 0.6 cm × 0.8 cm to 1.2 cm × 1.5 cm and the flap size ranged from0.8 cm×2.5 cm to 1.6 cm×4.2 cm.We put the head end of flaps at defect side.The horn perforator flap was designed with 1-2 perforator vessel and rotated to cover the defect.The defect at donor site was closed directly.Results We got 4 symmetric arteries in palmar and back surfaces of fingers,2 for proper palmar digital arteries and 2 for dorsal digital arteries.The proper palmar digital arteries have a larger diameter which is the main source of blood supply for fingers.All 9 flaps survived after the operation.Both the recipient area and donor areas received sound healing.With 2 months to 1.5 years of follow-up visit,the shape,color and luster,texture and function all had good healing.Conclusions The horn perforator flaps for repair finger soft tissue defect have advantages of flexible design,reliable perforator vessels.The defect at donor site can be closed directly with no skin graft.This method considers both shape and function and is a good way for finger soft tissue defect.

Checking the accuracy of references cited in Compendium ofMateria Medica is of significance for the research of Compendium ofMateria Medica.Furthermore,it can also serve as an example for ex-ploring the general rule on citations of historical documents by ancient authors.It has been found that there is a regularity in the format of the title of cited references,including book title,abridged title,alias title,author (surname,given name,secondary name,alternative name),name of reviser (surname, given name,secondary name,alternative name)etc.These references yield important significance for the discipline of literature.For example,by verifying the true and false of various editions of WU Rui’s Materia Medica in Daily Use of the Yuan Dynasty,the author of Dietetic Materia Medica of the Ming Dy-nasty and the true and false of its various editions can be thus confirmed.It is found that within the 276 references cited in the Compendium ofMateria Medica,64 cited references weren’t recorded in the for-mer bibliographies.Moreover,there were also other problems appearing in these cited historical docu-ments,such as two different books confused as one book,overlapping of books repeatedly,wrong cited book title,mistaken author,and with reference title but not really quoted etc.All these should be paid attention by the readers.
