Objective To explore prospectively the relationship between treatment of toxoplasmosis and pregnancy outcome. Methods Detected by ELISA and PCR,59 pregnant women and 91 women at reproductive age with infection were treated by oral spiramycin. Then their Tox-lgM and DNA negative conversing rates,intrauterine transmission rate and incidence of abnormal pregnancy outcome were studied in contrast to those of 60 women in pregnancy and 79 at childbearing age with infection but without management. Results In healing group,the seroconversion rate of Tox-lgM and Tox-DNA from positive to negative were 83.05% (49/59) in pregnant women and 70.33%(64/91) in women at childbearing age,respectively. The rates in control group were 35% (21/60) and 37.97% (30/79). The rates of intrauterine transmission and abnormal pregnancy outcomes of healing group were 8.4% (5/59) and 30% (15/50),respectively. While those of control group were 11.86% (7/59) and 40% (20/50) accordingly (? 2=11.4970,P

There were 48 strains of bacilli obtained from 20 Chinese traditional medicines. Twenty-five strains had antagonistic effect against at least one of ten plant pathogens. Seven strains had antibiosis to more than four pathogens and the best strain had antibiosis to nine pathogens. After physiological and biochemical experiments,eight strains of 25 antagonistic bacilli were proved to be Bacillus subtilis,three were Bacillus cereus,one were Bacillus natto and one were Bacillus licheniformis. At the same time,two kinds of Chinese traditional medicines,which probably had antibacterial effect,were found.

Objective This study has explored the role of antibody against annexin A2 in patients with antiphospholipid syndrome (APS) and systemic lupus erythematosus (SLE). Methods Using purified recombinant annexin A2, IgG anti-annexin A2 antibody was measured by ELISA in 101 APS patients, 41 SLE patients with thrombosis, 124 SLE patients without thrombosis and 120 healthy controls. Results The positive rate of IgG anti-annexin A2 antibody in APS patients and SLE patients with thrombosis was 21.8%, 26.8%, respectively, they were all significantly higher than in SLE patients without thrombosis (6.5%). IgG anti-annexin A2 antibody was associated with thrombosis and/or pregnancy morbidity (P<0.01). Conclusion Anti-annexin A2 antibody is associated with thrombosis and/or pregnancy mnrbidity. It suggests that anti-annexin A2 antibody may be helpful in identifying in some potential AIRS.

BACKGROUND:The biological substances fixed onto the implant surface, including specific proteins, enzymes, polypeptides, could promote the proliferation and differentiation of osteogenic cells in order to achieve a good osteogenic effect.
OBJECTIVE:To introduce the biological characteristics of the arginine-glycine-aspartic acid (RGD) peptides, cellbiological behavior and implant osseointegration in osteoporosis.
METHODS:Authors retrieved the relevant articles in PubMed database (January 1984 to January 2013), Wanfang database (January 2002 to December 2012) and CHKD database (January 2002 to December 2012) using the key words“RGD peptides, osteoporosis, bone marrow mesenchymal stem cells, osseointegration, osteoblast, induced differentiation”. Papers were included concerning the biological characteristics of RGD peptides, the biological behavior of cells and the bone-implant integration in osteoporosis.
RESULTS AND CONCLUSION:Osseointegration on the surface between implant and bone tissue can be further improved by grafting biological y active substance. Bionics modification, to simulate the extracellular matrix environment in vivo, can promote celladhesion and growth, which is an effective way to improve osseointegration and is also an important direction of research in the field of tissue engineering recently. The future research is focused on designing specific and efficient polypeptides and simple and effective fixation methods.

To explore the correlation between the ecological factors and the contents of podophyllotoxin and total lignans in root and rhizome of Sinopodophyllum hexandrum, podophyllotoxin in 87 samples (from 5 provinces) was determined by HPLC and total lignans by UV. A correlation and regression analysis was made by software SPSS 16.0 in combination with ecological factors (terrain, soil and climate). The content determination results showed a great difference between podophyllotoxin and total lignans, attaining 1.001%-6.230% and 5.350%-16.34%, respective. The correlation and regression analysis by SPSS showed a positive linear correlation between their contents, strong positive correlation between their contents, latitude and annual average rainfall within the sampling area, weak negative correlation with pH value and organic material in soil, weaker and stronger positive correlations with soil potassium, weak negative correlation with slope and annual average temperature and weaker positive correlation between the podophyllotoxin content and soil potassium.

Objective ① To investigate the level of the vitamin D endocrine system in peripheral relationships with bone mineral density (BMD) and the disease activity respectively. Methods The level of the 25-hydroxylate vitamin D3 (25OHD3) and 1,25-dihydroxyvitamin D3 [1,25(OH)D3] in plasma from 43 SLE patients and 44 normal controls were detected by enzyme linked immunosorbent assay. Vitamin D receptor (VDR) gene expression was determinied by real-time PCR in peripheral blood. BMD measurements in the lumbar spine (L1-4) and left proximal femur (femoral neck) were performed using dual X-ray absorptiometry before treatment. The relationship between the vitamin D endocrine system and the bone mass were studied. We also discussed the relationship between the vitamin D endocrine system and the disease activity. Results The levels of 25OHD3 and 1,25 (OH)2D3 were lower in the initial SLE patients than normal controls (P<0.01, P<0.01). The expressions of VDR gene were significantly increased in initial SLE compared with normal controls (P<0.01). The initial SLE patients had significantly lower BMD values, and higher frequency of osteopenia (35%) at both sites of measurement compared with matched healthy controls (P<0.01). The initial SLE patients were divided into two groups by BMD, abnormal group and normal group. There were no differences in 25OHD3, 1,25 (OH)D3 and VDR gene expression (P0.05). There was no correlation between the vitamin D endocrine system and BMD in initial SLE patients. There was no correlation between the vitamin D endocrine system and the disease activity either. Conclusion Vitamin D endocrine system may play an important role in SLE, but the level of VDR gene is not correlated with BMD and disease activity.
