OBJECTIVETo provide quantitative foundation for the diagnosis of atlanto-axial rotatory subluxation by analyzing the various imaging features of normal atlanto-axial joints in neutral position and rotary functional position on the MSCT images.

METHODSForty-one normal volunteers were examined by CT on the atlanto-axial joint in neutral position and rotary functional position. By the observation and measurement of atlanto-dental interval (ADI), lateral atlanta-dental space (LADS), VBLADS and rotating angle of atlas on dentate (RAAD), the imaging manifestations and anatomical characteristics were analyzed and compared. In order to compare VBLADS and RAAD and make a correlation analysis between different age groups, 51 normal volunteers were divided into two groups: age younger than 45 years old group and age older than or equal to 45 years old group.

RESULTSThe dens in neutral position deviated in an angle range of (3.22±0.89)°. The articular facets of lateral atlantoaxial joint in rotary functional position had rotatory displacement and the range of the relative rotation angle was (33.85± 2.79)°. Through the correlation analysis of matching data, it could be concluded that there was no correlation between atlantoaxial relative rotation angle and VBLADS within a certain range. There were statistically differences of atlantoaxial relative rotation angle in rotary functional position between two groups.

CONCLUSIONMSCT imaging in rotary functional position can clearly show the anatomical structure and rotation function of a normal atlanto-axial joint, so as to provide a theoretical basis for the diagnosis of atlanto axial rotatory subluxation.

Objective To study the expression of microtubule-associated protein-2 (MAP-2) in the CA3 region of the hippocampus and any effect of acupuncture combined with exercise training on the recovery of learning and memory after experimental cerebral infarction.Methods Eighty Wistar rats were randomly divided into a sham-operation group (n = 8 ) and an operation group (n = 72 ) subdivided randomly and equally into a model group, an exercisetraining group and an acupuncture plus exercise training group, with 24 rats in each group. After right middle cerebral artery occlusion or a mock operation, the expression of MAP-2 in the CA3 region of the hippocampus was detected with immunohistochemistry 1, 3 and 5 weeks after the operation. Learning and memory function was assessed at the 5th week post operation.Results MAP-2- positive fibers were arranged in an orderly way and distributed densely in the shamoperation group. After cerebral infarction, number of MAP-2 positive neurons and dendrite fibers decreased in the CA3 region of the affected side. A week after the operation, MAP-2 positive fibers had increased significantly in the acupuncture plus exercise group compared with the model group and the exercise group. At the 3rd and 5th week post operation, expression of MAP-2 and optical density had increased significantly compared with the model group and the exercise training group. At the 5th week post operation, Y maze discrimination and learning tests showed that learning and memory had improved significantly more in the acupuncture plus exercise training group compared with the model group and the exercise training group.Conclusions Exercise training combined with acupuncture can promote changes in dendritic plasticity and increase MAP-2 expression in the CA3 region after cerebral infarction. This may be correlated positively with the recovery of learning and memory after cerebral infarction, at least in rats.

Objective To study the apoptosis of multiple myeloma cell line KM-3 induced by NK cells. Methods WST-1 assay was used to detect the killing effect of KM-3 cells treated with NK cells at different effector(E):target(T) ratio. Flow cytometry was applied to analyze Annexin-V+/PI- apoptotic cells and the mitochondrial transmembrane potential. Results NK cells could significantly kill KM-3 cells in a dosand time-dependent manner (P <0.05). After KM-3 cells- were treated with NK cells for 48 hours, the Annexin-V+/PI- cells were increased obviously in dose-dependence (P <0.05). The Annexin-V+PI- cells were increased in time-dependence when treated with NK cells(E:T ratio at 10:1) (P<0.05). The mitochondrial transmembrane potential of KM-3 cells treated with NK cells were significantly decreased in dose-and time-dependence (P < 0.05). Conclusion NK cell can kill KM-3 cells and induce apoptosis in a dose-and time-dependence manner.

A method for the determination of three volatile elements (mercury, arsenic and selenium) in soils by one-time digestion was established.The digestion of samples was carried out in an automatic program temperature controlled graphite digestion instrument by aqua regia + hydrofluoric acid+boric acid.Hydride generation atomic fluorescence spectrometry (HG-AFS) was used to determine the contents of mercury, arsenic and selenium in the same digestion solution.The accuracy of the method was verified by the results of the soil environment samples of certified reference materials GSS-1-GSS-8 from the Center of the National Standard.The contents of soil mercury, arsenic and selenium obtained by this method were consistent with the standard values of these elements provided by the Center of the National Standard.In comparison with the current standard methods, the one-time digestion method was simplified, the pre-processing time was saved, and the reagent consumption was reduced.The method had wide range of application, high sensitivity, low detection limit, which was especially suitable for trace analysis of bulk samples, and also it could be used as a rapid digestion method for the measurement and governance of heavy metals in polluted soils.

Naringin has been reported to possess a wild range of biological activities. However, the route and metabolites of naringin produced by intestinal bacteria are not well understood. In this paper, different bacteria were isolated from human feces and their abilities to convert naringin to different metabolites were studied. Ultra performance liquid chromatography-quadrupole time-of-flight mass spectrometry (UPLC-Q-TOF/MS) with automated data analysis software (MetaboLynx) was applied to fast analysis of naringin metabolites. Using MSE and mass defect filter techniques, three metabolites were detected and tentatively identified. The results indicated that acetylation, hydrolyzation and hydrolyzation with hydrogenation were the major metabolic pathways of naringin in vitro. Then, we studied the gene sequence of the 16S rRNA of the bacteria by extraction of genomic DNA of the strain, PCR amplification and clone of the 16S rRNA. The consequence proved that Enterococcus sp.30, Bacillus sp.46, Escherichia sp.54 and Escherichia sp.63 have the peculiar metabolism characteristic of naringin.
