Energy expenditure of five young adults worked in the hot desert environment were measured by the methods of indirect calorimetry in the Wuwei Gansou in July 1989.The results indicated that the basal metabolism rate, the resting metabolism rate and the energy cost of young adults marching in the desert and Gobi (15kg load, at rate of 3.5km/h) were 2.782,3.059,14. 188, 10.305 kJ? m-2?min-1 respectively. It was shown that under the similar conditions energy expenditure marching in the desert was 38% more than in the Gobi.Ambient temperature had a greater effect on energy expenditure but the effect was various at different activities. When at 24.5-38.4℃ during marchi-ng(15kg load),1℃increase in ambient temperature was associated with anincrease of about 0.86% energy consumption. While at 25-33℃ during quiet rest the energy consumption tended to decrease with an increase of ambient temperature. But at 33-40℃ it increased with ambient temperature again. It is suggested that the energy metabolism may be more easily influenced by ambient temperature when the metabolic heat production of human body is increased.The present study recommended the estimation of energy requirement for the adult with a moderate activity in hot desert environment should be approximate 15.062MJ/d

AIM: To Structure a series of diversifying combination of ginsenoside in order to provide the different samples for the pharmacological and pharmacodynamics experiments. METHODS: UNIFAC group contribution method is used for simulating the liquid liquid extraction, the proper extractants are chosen to carry out the experiments, and then the contents of the ginsenosides obtained with different extractants are detected through HPLC. RESULTS: The contents of the main ginsenoside varied with the change of the extractants' ratio, as a result a series of diversifying combination of ginsenoside are constructured. Within the ginsenoside which has greater amount, ginsenoside Rb 1 can be easily separated from Re, while Rd is hard to be separated, the experimental data were accordant to the theoretical prediction. CONCLUSION: Theoretical calculation combined with the optimizing of the extractants can structure a series of distinguished ginsenoside.

Objective To explore the efficacy of catheter-directed thrombolysis (CDT) for acute deep venous thrombosis (DVT) of lower limbs.Methods The clinical data of 36 patients with acute DVT of lower limbs treated by CDT form September 2009 to September 2013 were analyzed respectively.Efficacy were assessed through observation of the circumferences,venous patency score and venous patency rate before and after thrombolysis.Results After treated by CDT,the effect of only 1 case with left lower limb DVT associated with inferior vena cava thrombosis was not obvious.The effects of 22 cases were excellence,and 13 cases were good.The total efficiency was 97.2％(35/36).The venous patency scores before and after CDT were (11.85 ± 1.12),(3.6 ± 1.53) points,and there had significant difference (P ＜ 0.01).After CDT,the venous patency rate was (69.6 ± 14.8)％.Conclusion Multi-channel CDT with small saphenous vein for acute DVT of lower limbs is safe and effective,with less invasion and quicker recovery.It is worthy of promotion in clinic.

BACKGROUND: Both hydroxyapatite (HA) and large diameter TiO2 nanotubes have excellent biocompatibility, but bone-forming ability of nano-HA (nHA) deposited large diameter TiO2 nanotubes is rarely reported.OBJECTIVE: To evaluate the bone-forming ability of nHA/large-diameter TiO2 nanotube composite coating.METHODS: Large-diameter TiO2 nanotubes were prepared by anodic oxidation method, and then nHA was electrochemically deposited on the surface of TiO2 nanotubes. Preosteoblasts MC3T3-E1 were co-cultured with the nHA/large diameter TiO2 nanotube composite, pure titanium and TiO2 nanotube coatings, respectively. At 0.5, 1, 2 hours after culture, the initial cell adhesion was observed. At 1, 3, 5 day after culture, cell proliferation was assessed. At 2 days after culture, cell morphology was observed. At 3 and 7 days after osteogenic induction, intracellular alkaline phosphatase activity was detected. At 14 days after osteogenic induction, mineralization of extracellular matrix was detected.RESULTS AND CONCLUSION: (1) After 2 hours of culture, the number of adherent cells on the composite coating was significantly lower than that on the TiO2 nanotube coating (P < 0.05), but slightly higher than that on the pure titanium coating with no statistical difference. (2) After 1, 3, 5 days of culture, the cell proliferation on the composite coating was significantly lower than that on the TiO2 nanotube coating (P < 0.05), but slightly higher than that on the pure titanium with no statistical difference. (3) The cells on the pure titanium showed a spindle-shape, while those on the TiO2 nanotube coating processed filopodia. The cells on the composite coating showed polygonal shape with a larger number of filopodia. (4) The intracellular alkaline phosphatase activity of the composite coating group was significantly higher than that of the pure titanium group and TiO2 nanotube group. The trend of mineralization of extracellular matrix was ranked from high to low: the composite coating group > TiO2 nanotube group > pure titanium group. To conclude, the nHA/large diameter TiO2 nanotube composite coating not only has good biocompatibility, but also has the ideal ability to promote bone formation.

Objective To investigate the diagnostic value of mammography,3.0T MR and the combination for benign and malignant breast lesions.Methods Sixty-one patients with breast lesion proved by postoperative pathology included 47 malignant cases and 14 benign cases.Imaging indexes were recorded and analyzed for all cases,including TIC type,ADC value and whether the Choline peak was detected on MRS.SPSS 17.0 statistical software package was used for analysis.Chisquare test was used for count data and P<0.05 was considered as statistically significant.Results The accuracy were 45.9% and 62.3% respectively for mammography or MR as a sole method for the diagnosis of benign and malignant breast disease.When combining the two techniques,the diagnostic accordance rate was 80.3%.The rate based on the combination of mammography and MR were higher than on basis of either kind of examination along, with a statistically significant difference (χ2=4.08,P<0.05).Conclusion MR examination was superior to mammography for the diagnosis value of benign and malignant breast lesions.When combining mammography with MR examination,it could not only obviously improve the accuracy of preoperative diagnosis of breast cancer but also provide the theoretical basis for the early diagnosis and the prognosis.
