Objective To explore the influence of self-management education on quality of life of patients with deep vein thrombosis. Methods 60 cases of deep vein thrombosis patients were randomly divided into the experimental group and the control group with 30 cases in each group, two groups basically received the same medication treatment, the control group held conventional health education, The experimental group implemented self-management education.Life quality was compared before education and 3 months after education was compared between the two groups. Results Before self-management education, the scores of quality of life of the two groups showed no difference; after three months of selfmanagement education, the score of body's function, psychological function, social function and total score of quality of life were obviouly different.However, there were no significant differences in material life. Conclusions Self-management education can improve the quality of life of patients with lower extremity deep vein thrombosis.

AIM: To investigate the effects of rosiglitazone on fibroblast-like synoviocyte ( FLS )-induced osteoclastogenesis in rheumatoid arthritis ( RA) and the related mechanism.METHODS: RA-FLS were cocultured with peripheral blood monocytes from healthy volunteers in the presence of macrophage colony-stimulating factor ( M-CSF) and rosiglitazone.Osteoclasts were assayed by tartrate-resistant acid phosphatase ( TRAP) staining.Resorption lacunae area was identified by toluidine blue staining and quantified by image analysis software.The mRNA expression of RANKL and OPG was evaluated by real-time PCR, and the protein levels of RANKL, OPG, p-ERK, p-p38 and p-JNK were measured by Western blot.RESULTS:Compared with control group ( without rosiglitazone treatment) , rosiglitazone at concentration of 15 μmol/L significantly decreased the number of osteoclasts (P<0.01) and resorption lacunae area (P<0.05).The expression of RANKL at mRNA and protein levels was significantly down-regulated by rosiglitazone at concentration of 15μmol/L, while the mRNA and protein expression of OPG was up-regulated (P<0.01).Rosiglitazone (15 μmol/L) sig-nificantly decreased the protein level of p-ERK ( P<0.05 ) , but not the protein level of p-p38 or p-JNK ( P>0.05 ) . CONCLUSION:Rosiglitazone inhibits RA-FLS-induced osteoclast formation and its resorption activity by down-regulating RANKL expression and ERK phosphorylation, suggesting that rosiglitazone may inhibit RA osteoclastogenesis and bone re-sorption.

Objective: To investigate the childrens congenital and acquired nutritional status and the physical development among the different nationalities in Guizhou province; to find out the factors that greatly influence the childrens physical development. Methods: Investigations were carried out on the diet, height and the weight of the mothers during the early and late stage of their pregnancy and after the delivery of the babies. Results: The living conditions in the groups of Miao and Buyi were very poor. For the pregnant women among Han, Miao and Buyi groups, during their middle and late stage of the pregnancy, the intakes of protein, calcium and VB 2 did not reach 80% RDA. For the 2-4 years old children, the intake of protein was below 80% RDA. For those in Miao and Buyi groups, the chief source of protein was from cereals. There was a great insufficient intake of calcium and VB 2 in different age groups of the children mentioned above. With the increase of age, the infants of Buyi and Miao groups were gradually diverting from the standard criterion from 3rd or 4th month. The greatest difference was in Miao group, i.e. at the age of 6, the difference in height was 9.8 cm(male), 8.3 cm(female); the difference in weight was 1.64 kg(male), 1.92 kg(female). Conclusion: The physical development of the infants in Buyi and Miao groups is inferior to those in Han group. Besides the environmental influence, the quality and quantity of the protein in diet play an important role in physical development.

Objective: Xiaoliu Granule (XLG) is based on the principle of Yiqi Huayu Decoction, this experiment was to study the treating point of XLG on the hysteromyoma rats. Methods: The hysteromyoma rats models was established in rats by loading estrogen and progesterone, to observe the effect of XLG on pathological condition of uterus, and the content of PR , ER, Bcl-2/Bax. Results: The experiments proved that XLG was effective in reducing the proliferation, reversing the proliferative abnormalities of uterus smooth muscle. The XLG also can significantly reduce the content of PR, ER and Bcl-2/Bax. Conclusion: Therefore, XLG was a good approach in treating hysteromyoma. The mechanism of XLG in treating hystermyoma was probably by reducing ER, PR, lowering the E, P sensitivity; reducing expression of Bcl-2, increasing the expression of Bax, and promoting cell apoptosis, etc.

Cough recognition provides important clinical information for the treatment of many respiratory diseases. A new Mel frequency cepstrum coefficient (MFCC) extracting method has been proposed on the basis of the distributional characteristics of cough spectrum. The whole frequency band was divided into several sub-bands, and the energy coefficient for each band was obtained by method of principle component analysis. Then non-uniform filter-bank in Mel frequency is designed to improve the extracting process of MFCC by distributing filters according to the spectrum energy coefficients.
