BACKGROUND: Senility is the degenerative change of every tissue and organ in biological body,which is the result due to comprehensive actions of various pathological and physiological processes. Rhodiola is a kind of natural medical plant,acting on delaying organic senility,preventing and treating senile disorders,etc. But the definite mechanisms on those have been unknown yet.OBJECTIVE: To probe into the mechanism of rhodiola extract( nuodikang capsule) on anti-senility.DESIGN: Randomized,controlled experimental research based on the experimental animals.SETTING: Neurological internal department in a military hospital affiliated to a university of Chinese PLA.MATERIALS: The experiment was performed in Pathology Experiment Room of Fourth Military Medical University of Chinese PLA from March to August 2002. Sixty Kunming mice were randomized into normal control group,model group,3 dosage groups of 1,2,4 g/kg of nuodikang successively and Vitamin E(Vit. E) positive control group 0. 1 mg/kg,10 mice in each group.INTERVENTIONS: In the model,nuodikang groups and Vit. E positive control,physiological saline solution of D-galactose 30 g/Lwas applied in subcutaneous at the back of neck,150 mg/kg per day,continuously for 8weeks. Simultaneously,in nuodikang group and Vit. E positive control,the medicine was applied by gastric perfusion,once daily,continuously for 8weeks.MAIN OUTCOME MEASURES: Effects of nuodikang capsule on activity of lactate dehydrogenase(LDH),the content of lipidperoxides(LPO),the activity of superoxide dismutase(SOD) in the brain,the content of malondialdehyde (MDA) and ultrastructure of mitochondrion in hippocampal neurons.RESULTS: In nuodikang capsule groups of 1,2,4 g/kg,the significant differences(P ＜ 0.05) presented in LPO content in brain tissue[(30. 1±2.9),(27.8±3.1),(26.9±1.9) nmol/g] and MDA content [(110.2±13.5),(95.4±20.1),(90.2±16.5) nmol/g],1 compared with the model group[ (33.4 ± 2.2),(126.5 ± 17.2) nmol/g],indicating significant differences(P ＜ 0.05),and LDH activity[(1.74±0. 14),(1.92 ±0. 23),(2.04 ±0.21) NU/g] and SOD activity[ (119. 1 ±2.2),(121.3 ± 0.9),(126.4 ± 2.0) NU/g] were remarkably increased,compared with the model group[ (1.68 ±0. 19),(115.9 ±2. 1) NU/g],indicating significant differences( P ＜ 0.05) . It was indicated by electro-microscope that nuodikang capsule groups of 2,4 g/kg acted on obvious protection on degenerative change of mitochondrion in hippocampal neurons caused by galactose.CONCLUSION: Nuodikang capsule acts significantly on anti-senility,which is related to its anti-oxidative injury and protection on neurons.

Objective To explore the tumor markers for the diagnosis of primary liver carcinomas (PLC) by detecting the serum protein spectrum differently expressed between PLC patients and healthy controls. Methods We detected the serum protein spectrum in 50 PLC patients and 50 healthy controls using surface enhanced laser desorption ionization time-of-flight mass spectrometry (SELDI-TOF-MS) technique and find the significant protein peaks. The serum Alpha-fetoprotein (AFP) levels in all 100 serum samples were also measured by ELISA. Results The protein peaks, which could discriminate healthy individuals from PLC patients, were detected. Four protein molecules (3354.71, 8825.80, 4345.08, 13 715.01) had a significant difference between PLC patients and the normal controls (P <10-5), indicating that these protein molecules might be a potential marker for PLC. The specificity and sensitivity of SELDI-TOF-MS were 94% and 90% respectively. Sixteen PLC patients were AFP positive and the sensitivity was 54%(27/50). Conclusion With a high specificity and sensitivity, the detection of serum protein spectrum can be performed easily and quickly by SELDI-TOF-MS technique, which provides a serological way in identifying PLC and most likely to benefit from AFP strategies.

Percutaneous vertebroplasty has many advantages such as minimal trauma, simple mode of operation, rapid and correct therapeutic effect, high safety, and wide indications. Therefore it has been generally paid close attention and accepted. Percutaneous vertebroplasty has conspicuous curative effect, especially in vertebral compression fracture. Polymethyl methacrylate is the most used filling materials at present; There is not significant difference between unipedicular and bipedicular vertebroplasty; Using vertebral body venography and appropriate dense bone cement can reduce leakage of bone cement; Bolster for self-replacement can rebound vertebral body height, and balloon kyphoplasty and sky bone expander kyphoplasty can be avoided; In order to reduce refracture of vertebral body, anti-osteoporosis drugs should be used in the treatment of percutaneous vertebroplasty.
