Objective To explore the effect of photon on blood biologic components in blood photochemical treatment. Methods After the blood sample was adjusted to an appropriate density, it was treated with 0.1 nmol/ml 8-MOP (8-methoxypsoralen), 0.1 nmol/ml TFO (triple helix-forming oligonuletide) and UVA (ultraviolet A radiation) at the intensity of 1 800 μW/cm2 for 3~20 min. The changes of biologic activities of major components in blood were measured with automatic blood gas analyzer, platelet aggregation analyzer, blood coagulation analyzer, micropipette aspiration system and assay of poly-lysine adsorption. Results The oxygen content in blood was increased gradually. The resilience of erythrocyte was enhanced ,but its adhesiveness was decreased. The parameters related to blood coagulation had some changes but all remained within the normal ranges. Conclusion Under the definite condition of blood virus being inactivated effectively, the nonspecific effect of photosensitive response may improve blood oxygen content, enhance the transfiguring ability of erythrocyte and decrease the blood viscosity, but having no obvious change on blood coagulation.

Objective To study the tactics, methods and relevant factors of transcatheter embolization for acute gastrointestinal hemorrhage.Methods Fifteen patients with acute gastrointestinal hemorrhage were embolized by one of the methods of Polyvinyl Alcohol (PVA), gelfoam or metal coils. Four of the fifteen patients were upper gastrointestinal hemorrhage, the other cases were lower gastrointestinal hemorrhage which were embolized using coaxial microcatheter. Results Fourteen of the fifteen patients were treated successfully by these methods. There were total 17 times of embolization for 16 parts, the success rate reached 94.1%. The other one reveaded an infarction of intestine after the embolization and was cured by resection. One of the fifteen patients appeared a recurrent hemorrhage 3 months later, and confirmed to be a hemangiolymphangioma. Two patients with malignant tumor were operated upon selectively. The other patient of intestinal hemorrhage was embolized successfully by using a metal coil after shock. Leiomyoma complicated with large area of bleeding was finally proven by operation.Conclusions Transcatheter embolization for acute massive gastrointestinal hemorrhage is safe and efficient under different choice of methods. The key of success is the right selection of embolized target artery and dosage of emboli.

Journal of Interventional Radiology 2015;(6):540-543
With the rapid development of nanotechnology, nano oncology medicine that is formed through the combination of nano science and oncology medicine has become an important field emerging in nano science. Because of its unique optical properties, the gold nanorod (GNR), that is a rod-shaped nano materials, has shown great potential applications in the biomedical field, especially, in GRNs thermotherapy, radio-sensitizing effect therapy and targeting therapy of the tumor. Being a newly-developed therapy, gold nanorods combined with internal radiotherapy has already obtained excellent durative effect in targeting therapy of tumor. This paper aims to make a comprehensive review about its mechanism and its clinical application and research situation in recent years.

Objective To discuss the relationship between the fracture of the clavicle which was fixed by tor-sional-shaped plate and nonunion after operation.Methods Retrospective analysis was conducted in 426 patients with midshaft clavicle fractures.Among the patients,the A group used torsional-shaped plate to meet the anatomical structure of the clavicle:the medial plate matched under the front face of the clavicle,and the lateral plate matched the up face of the clavicle.And the traditional method was used in the B group.Patients were followed up for at least 12 months,the patients were judged by X-ray criteria for nonunion.Results A total of 28 patients with nonunion, including 4 cases in A group,24 cases in B group.After statistics processing,the difference between A group and B group was significant (χ2 =6.679,P=0.010).Conclusion We find that the treatment of the fracture of the middle part of the clavicle with torsional-shaped plate can effectively reduce the incidence of nonunion.

Patrolling monocyte (PMo) is a subset of monocytes.Its main function is patrolling vascular endothelium and removing cellular debris from the microvasculature.Studies have revealed that PMo can inhibit the growth of tumor cells,recruiting NK cells to kill tumor cells.PMo can prevent tumor cells metastasis to the lung,which plays a role of immunosurveillance.PMo may be a target for cancer immunotherapy.

Objective To study the effect of a polysaccharide from cuscuta chinensis lam (PCCL) on antisenility and its mechanism. Methods Sixty Kunming mice were randomized into 6 groups. The three PCCL groups were administrated with PCCL of 100, 200, 400 mg?kg -1?d -1 orally, the positive control group with vitamin E of 200 mg?kg -1?d -1, the model group and control group with the same volume of control solution only. At the same time, the model group, the positive group and the three PCCL groups were subcutaneously injected of 5% D-gal at the dose of 0.5 ml at the nape, and the control with the same volume of saline solution. Seven weeks later, the MDA, SOD activity, GSH-PX activity in the liver and kidney of mice and lipofuscin (LF) in mouse brain were detected with the methods of TBA, Nitrate, DTNB and Sohal, respectively. The data were analyzed with SPSS software and the data between groups were analyzed with one-factor variance analysis. Results Thymus index and spleen index dropped, LF rose in brain, malondialdehyde (MDA) content rose and the activities of superoxide dismutase (SOD) and glutathione peroxidase (GSH-PX) dropped in liver and kidney in senile mouse model. PCCL administration of 100, 200, 400 mg?kg -1?d -1 made thymus index and spleen index rising, LF dropping in brain, MDA content dropping,SOD and GSH-PX LF rising in liver and kidney of senile mouse model. Conclusion PCCL may postpone senility, which mechanism probably connected with rising immunity, eliminating oxygen free radicals and antilipoperoxidation.
