The molecular compositions of PCE-CGH and PCE-CGL were investigated by chromatography and chemical analysis. Rhamnose, arabinose, glucose and galactose were proved to be the main strctural unit of PCE-CGH, and trifle glucoronic acid was identified in the molecule. The compositions of PCE-CGL were relatively complicated. Inositol and amino sugars besides for glucose and galactose were also identified in its molecule.

Twenty-four sites were sampled over three different periods in three rivers of the plateau. At each site, a riffle and a pool were identified, in a stretch of about 100 m, as separate habitat units, and were sampled for fish and physical habitat. A preference index and logistic regression were used to determine the important habitat variables for each species.

The system utilized four laser scanners along lengthwise direction of the log. Data are obtained in every ten degrees when log is turning, in each cross section, 36 data are obtained. Then the data obtained were processed and an outline of the cross section of the log was developed on computer screen. Afterwards, the largest inscribed circles for log cross sections were determined according to the principle that three points can determine a circle. Secondly, the points located on the cross sections were linked up along some log generative in order to simulate the three-dimension log outline. At last the largest right circular cylinder were optimized and the optimum turning center was determined by means of projective theory.

Methods Mouse models of tibia fracture healing were established, and callus samples were collected 1, 3, 7, 14, 21 and 28 days after fracture. The development of callus and new bone formation were evaluated with roentgenology, Micro-CT and tetracycline double labeling method, and the expression of HIF-1α, vascular endothelial growth factor, Runx2 and ALP in callus were detected with RT-PCR, Western blotting and immunohistochemistry. The relationship between HIF-1α and fracture healing was analysed.

Accuracy between two groups was calculated byχ~2 test.Calculate the average effective radiation dose of the 30 patients.Results In group A,seventeen patients underwent both DSCT coronary angiography and SCAG,among 255 segments of 17 patients,105 lesion sites of 70 segments were diagnosed stenosis or obstruction,of them,95 lesion sites were confirmed by SCAG.The accuracy of DSCTCA was 90.48%.The agreement of two methods have a high agreement(Kappa =0.853).In group B,13 patients underwent both DSCT coronary angiography and SCAG,among 195 segments of 13 patients,73 lesion sites of 57 segments were diagnosed stenosis or obstruction, of them,65 lesion sites were confirmed by SCAG.The accuracy of DSCTCA was 89.04%.The agreement of two methods have a high agreement(Kappa =0.835). There was no significant difference(χ~2=0.098,p＞0.05) between the accuracy of two groups.The effective radiation dose of 30 patients was 3.67±0.43 mSv.Conclusion Compared with SCAG,prospectively ECG-gated transverse DSCT is a valuable examination to detect and diagnose coronary artery disease with a low dose coronary angiography.The accuracy of the DSCT is approximate to the SCAG.There was no significant difference between the accuracy of two groups.

Sims and Saleh performed pin site care daily beginning 48 hours after the operation. In their study, they applied Orthox monolateral xators (Orthox Srl, Bussolengo–Verona, Italy)(58.4%), circular xators (19.7%), and the Shefeld Hybrid System (21.9%). Massage was used to release skin adhered to the pin. A cotton swab with normal saline or cooled boiled water was used to clean the pin site. Another cotton swab was then used to dry the pin site. Dressings were only applied if there was any exudate. Bathing with the leg submerged in water was discouraged. They found that 29% of the xators had noinfection (grade 0) according to the grading system of Saleh and Scott (Table 5). The remaining 71% of xators had an infection of one or more different grades. There were no grade 6 infections. They concluded that xators located on the femurhad the highest infection rate and that incidence of infection was 2.5 times greater for femoral xators in which corrections were performed (62.3%) than in those without corrections (24.5%). These observations, however, were based on half-pin care. We did not use half-pins or Schanz screws in any of our treatment groups.
