OBJECTIVEThis study aims to test the accuracy and precision of iWitness photogrammetry for measuring the facial tissues of mannequin head.
METHODSUnder ideal circumstances, the 3D landmark coordinates were repeatedly obtained from a mannequin head using iWitness photogrammetric system with different parameters, to examine the precision of this system. The differences between the 3D data and their true distance values of mannequin head were computed.
RESULTSOperator error of 3D system in non-zoom and zoom status were 0.20 mm and 0.09 mm, and the difference was significant (P 0.05). Image captured error of 3D system was 0.283 mm, and there was no significant difference compared with the same group of images (P>0.05). Error of 3D systen with recalibration was 0.251 mm, and the difference was not statistically significant compared with image captured error (P>0.05). Good congruence was observed between means derived from the 3D photos and direct anthropometry, with difference ranging from -0.4 mm to +0.4 mm.
CONCLUSIONThis study provides further evidence of the high reliability of iWitness photogrammetry for several craniofacial measurements, including landmarks and inter-landmark distances. The evaluated system can be recommended for the evaluation and documentation of the facial surface.

Proteins extracted from two varieties of Chinese roses leaves were separated by two- dimensional polyacrylamide gel electrophoresis (2-DE) with immobilized pH gradient (IPG). Many difference proteins were isolated with molecular weights ranging 10-30 kDa and pI5-6. Three proteins of high levels observed in a gel were excised and identified using peptide mass fingerprinting and MS-MS. A summary of the identified proteins and their putative functions are presented. They are identified as eIF-5A、LEA protein and Hsp17. 5. Functions of these proteins in plant tolerance to high temperature were discussed.

OBJECTIVETo observe clinical efficacy of renovation stem revision femoral head arthroplasty for the treatment of unstable intertrochanteric fracture in the elderly.
METHODSTotally 32 elderly patients with unstable intertrochanteric fracture were treated with renovation stem revision femoral head arthroplasty from September 2007 to January 2011. There were 11 males and 21 females with an average age of 83.8 (ranged, 80 to 98) years old,the time from injury to hospital ranged from 4 h to 14 days. According to Evans-Jensen classification, 6 cases were type II a, 20 cases were type II b, and 6 cases were type III. Postoperative mortality, complication rates and Harris hip function score were compared and analyzed to evaluate curative effect.
RESULTSAll patients were followed up and no dislocation occurred. Six patients were died during 15 months and 4.5 years; 24 cases recoved to independent wakling at 6 months after operation, and 8 cases walked with stick and walker. The average Harris hip joint function score were (91.56 +/- 2.96), 28 cases got excellent results and 4 cases good. Nine cases occurred complications and healed after treatment.
CONCLUSIONRenovation stem revision femoral head arthroplasty is a active and reliable method in treating unstable intertrochanteric fracture in the elderly.

The study aims to screen the ability of the bacteria to metabolize ononin and assess the effect of ononin on the intestinal bacteria. Fresh human fecal sample was obtained from a healthy volunteer, diluted serially in sterile water and sixty-nine different bacterial colonies were picked out ultimately. UPLC-Q-TOF/MS with automated data analysis software (MetaboLynx) was applied to fast analysis of ononin metabolites. Furthermore, an E(max) precision microplate reader was employed to determine the growth situation of Enterococcous sp., Enterobacter sp., Lactobacilli sp., and Bifidobacteria sp. Results indicated that hydrogenation, demethylation, hydroxylation and deglycosylation were the major metabolic pathways of ononin by human intestinal bacteria in vitro. Ononin can inhibit the growth of pathogen such as Enterococcus sp., Enterobacter sp. and can promote the growth of probiotics such as Bifidobacteria sp. and Lactobacilli sp. This study suggested that intestinal bacteria have the metabolic effects of ononin and the biotransformation was completed by different bacteria. And ononin can affect the balance of intestinal flora and the degree of influence varies depending on the bacterial species and the concentration of ononin.

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.

In terms of the relatively backward English teaching concept of medical colleges, a latest international teaching concept CDIO is combined into medical college English teaching, reflected and reformed theoretically and practically. Theoretically, the integration of CDIO, medical education and English teaching and its positive effects are analyzed. Practically, course system, teaching contents and teaching methods are reformed in a linear sequence of C, D, I and O to form a new teaching structure of bilateral promotion between basic English learning and medical English learning. Applying the concept of CDIO into medical college English teaching will be of great benefit to promote the English practice ability of medical college students.
