Hypertriglyceridemia-associated acute pancreatitis is an inflammatory disorder of exocrine pancreas caused by metabolism disturbances of triglyceride-rich lipoproteins.Currently,hypertriglyceridemia-associated acute pancreatitis is characterized by an escalating incidence rate,a tendency for more severe cases,and a lack of therapeutic drugs.Traditional Chinese medicine has distinct advantages in treating this disease,but its theoretical framework has not yet been established.Hypertriglyceridemia-associated acute pancreatitis manifests itself as a febrile disease,aberrant accumulation of fat and turbidity may stem from dietary imbalances and visceral dysfunction in ordinary individuals.The prolonged accumulation of fat and turbidity can transform into turbid pathogen,subsequently engendering heat,constituting a pivotal pathogenic factor.Throughout the progression of the disease,the fiery pathogen consumes the fat and turbidity,resulting in the generation of toxic heat,which is a crucial mechanism in the exacerbation of the disease severity.Thus,this article posits therapeutic principles aimed at averting the transformation of fat and turbidity into turbid pathogen and counteracting toxic heat in this disease.This article reviews two key theories from traditional Chinese medicine classics relevant to hypertriglyceridemia-associated acute pancreatitis:the theory of fat-turbidity associated with hypertriglyceridemia and the febrile disease related to acute pancreatitis.Combining these traditional theories with modern research on the mechanisms that intensify hypertriglyceridemia-associated acute pancreatitis and the corresponding targets of traditional Chinese medicine,it suggests that the pathogenesis of"fat-turbidity-toxic heat"serves as the theoretical basis of traditional Chinese medicine for the aggravated severity of hypertriglyceridemia-associated acute pancreatitis.The article aims to offer new insights for the treatment of hypertriglyceridemia-associated acute pancreatitis.

OBJECTIVEThis preliminary study aims to investigate the effects of titanium and titanium alloy micro-nano-dimensional topography on the biological behavior of osteoblasts in vitro.

METHODSElectrolytic etching (EE) method was used to produce micro-nano dimensional titanium surfaces. The surfaces were observed to determine their effects on the adhesion, proliferation, cell morphology, and alkaline phosphatase (ALP) activity of osteoblasts.

RESULTSThe surfaces of the titanium and titanium alloy groups exhibited higher adhesion and proliferation of osteoblasts than those of the mechanical group. The titanium surface was covered with a group of cells, a large number of filopodia, and functional particles. The ALP activity of the titanium group was significantly higher than that of the titanium alloy and mechanical groups.

CONCLUSIONEE method in pure titanium and titanium alloy surfaces result in bowl-like nests and nanostructures of different diameters and depths. The diameters of the pure titanium and titanium alloy surfaces range from 30 to 50 μm and 5 to 8 μm, respectively. The former is more conducive to promote the proliferation and differentiation of cells.

Objective To study the application of fusion of CT and MRI images in X-knife treatment for intracranial lesions.Methods Total 25 patients included:3 gliomas,3 acoustic neuroma,2 pituitary adenoma,one craniopharygioma to be remained or recurred postoperatily,2 pituitary micro-adenoma,5 AVM,4 cavernous angioma,3 metastatic tumour,one neoplasm located pituitary stem and midbrain respectively.Before the fusion of CT and MRI images MRI scan and CT scan for location of X-knife were performed respectively,then MR and CT image were transferred to workstation for the fusion of images.Results All lesions were showed clearly on fusional images and more nodules were observed in 3 metastatic tumour.Skull,soft tissue constructures and the profile of lesions were completely overlaped on overlaped images of CT and MR with an error less 1.0 mm.Conclusion CT and MRI images of head can be accurately registered.The images can show the radiologic informations more clearly than conventional CT image.It provides a safe,effective and little harmful method for X-knife treatment of intracranial lesions.
