Stathmin, a ubiquitously expressed cytosolic protein(Mr=19×10~3), is also called oncogene protein 18 (Op18). Stathmin is involved in the assembly of microtubule (MT) and spindle by binding the tubulin protein. It plays a key role in cell proliferation, differentiation, regeneration, and migration and has regulatory effects on the signal transduction. Recently, it is reported that stathmin is overexpressed in a variety of human malignancies. It induces tumor cell migration and invasion by regulating MT depolymeri-zation. Its post-translational modification influences the interaction with p53 protein and is involved in the initiation and progression of malignant tumor. Stathmin alone or in combination with chemotherapeutics has been used for tumor therapy. The internal association of stathmin with cancer etiology is still unknown. So, further studies are needed to determine the role of stathmin as potential tumor biomarker and a drug target in tumor therapy.

Objective To explore the clinical significance of joint detection of β2‐microglobulin(β2‐MG) ,glycated hemoglobin and Cystatin‐C (CysC) in early renal injury in patients with diabetes mellitus .Methods 60 patients with early diabetic renal damage were in early diabetic renal damage group and 100 patients with simple diabetes mellitus were in simple diabetes mellitus group .50 healthy persons were the control group .Using immunoturbidimetry to detect the serum level of CysC ,immunoturbidimetry trans‐mission to detect the urine level of β2‐microglobulin and ion exchange high performance liquid chromatography method to detect the level of HbA1c .Results There were statistically significant differences in the level of β2‐MG ,glycated hemoglobin between early diabetic renal damage group and the other two groups (P<0 .05) .There were statistically significant differenees in the level of gly‐cated hemoglobin between simple diabetes mellitus group and healthy control group (P<0 .05) .Conclusion It is important for pa‐tients with diabetes mellitus to detect the β2‐MG ,glycated Hemo globin and CysC in diagnosis ,monitoring .prevention of early renal injury .

The quality of life(QOL) in patients with nasopharyngeal carcinoma ( NPC ) has attracted people' s attention increasingly. Most of the studies focus on measuring scale and influential factor. Both the disease itself and many non-somatic factors can affect the patients' quality of life. In this review, we summarize these research advancements on measuring scales and influential factors, considering that it need more studies regard to quality of life in NPC patients, and it is very urgent and important to work out the special measuring scale of NPCQOL that suits Chinese culture and value system.

BACKGROUND:Traditional studies on foot and ankle biomechanics have limitation. Ankle joint was complicated and had big range of motion, so it is difficult to establish finite element models and to analyze the type of fracture.
OBJECTIVE: To construct the finite element models of distal tibial fractures and analyze the stability.
METHODS: CT data of ankle were colected from a normal male volunteer and the three-dimensional reconstruction of volunteer was made by Mimics software, and the effectiveness was verified. The ratio of different joint involvement and height of fracture block were assumed with Solidwork software, and finite element models of distal tibial fractures were established. Fracture stability was analyzed by ANSYS software using finite element method.
RESULTS AND CONCLUSION:The distal tibia fracture model was consistent with the relevant literature data, and finite element analysis could be further conducted. The ratio of articular surface involved was positively associated with fragment height and fracture displacement, and negatively associated with fracture stability. These results indicate that the three-dimensional finite element models of distal tibial fractures were successfuly established. Fracture stability was associated with the ratio of articular surface involved and fragment height.

There are increasing experimental evidences and clinical data showing that inflammatory reaction plays an important role in the production and development of atherosclerosis. Inflammatory process promotes the production and release of inflammatory factors by activation of monocytes and stimulation of endothelial cells, which stimulate the migration and proliferation of vascular smooth muscle cells. Hydrolases and cytokines are released from the activated and stimulated cells to increase local lesion and form atherosclerotic plaque with the development of inflammation. So, on the basis of the new pathogenesis of atherosclerosis,scientists try to interfere with atherosclerosis by anti-inflammatory pathway. This paper reviews the progress of drugs against atherosclerosis by the modulation of C reaction protein ,CD40-CD40L,infection and NF-?B.

AIM To observe the protective effect of quercetin on vascular endothelial cells injured by homocysteine in rabbits. METHODS The model of the vascular endothelial cells of rabbits injured by homocysteine was established; 50 mg?kg -1, 100 mg?kg -1 and 200 mg?kg -1 of quercetin were orally adminstered. After 30 days, the number of CEC, levels of MDA and NO,SOD activity in the serum were determined; ET concentration in the plasma was detected. The thoracic aorta was isolated to observe the vascular reactivity to nitroglycerin and ACh and tissue change. RESULTS The number of CEC, levels of MDA and ET were decreased and levels of SOD and NO were significantly increased in the quercetin-administered group compared with the injured group.Non-endothelium dependent relaxation of vessel caused by nitroglycerin was similar in all groups. Endothelium dependent relaxation caused by ACh was reduced in the injured group,whileas the relaxation trended to the normal degree in the quercetin-administered group. Pathological examination showed that quercetin was effective on the injured endothelial cells. CONCLUSION Quercetin produces protective effect on the injured vascular endothelial cells by homocysteine in rabbits.

Objective To analyze and evaluate the related data of bottom clearance in Fuling section of Three Gorges Reservoir. Methods Bottom clearance in Fuling section of Three Gorges Reservoir was carried out in Fuling district during the period from May to December in 2002. All the data related to clearance were collected before and after the bottom clearance. Based on the collected data, the effect of clearance was assessed. Results 5 882 general pollution sources, 68 contagion pollution sources were cleaned in Fuling district, the clearance rates of both were 100%. The rat densities in agriculture areas and the dismantling cities were 3.97% and 2.97% respectively before rat extinguishment, then became 0.65% and 0.33% after rat extinguishment. Conclusion Through the bottom clearance of Three Gorges Reservoir, contagion and general pollution sources in the emigrant areas have been cleaned up, so water pollution in Three Gorges Reservoir and the rats mediated diseases have been prevented and controlled.
