Objective To study the genetic variation of two mitochondrial DNA molecules (CO1 and Cytb gene) of Oncomelania hupensis isolated from different areas. Methods Snails were collected from Jingxi of Guangxi,Yueyang of Hunan and Eryuan of Yunnan. Genomic DNA was extracted from the snails,Co1 and Cytb gene fragments were amplified by PCR,then purified and sequenced. Sequences of each isolates were edited by using Clustal W(1.82) software,and the nucleotide composition,transition and transversion were accounted by using MEGA(3.1) software. The genetic distances were computed with Kimura method and phylogenetic trees were constructed with UPGMA and MP method respectively. Results CO1 and Cytb gene fragments were about 700 bp and 600 bp(including 2 primers) respectively. A total of 106 mutation spots (15.9%) were tested in CO1 homological nucleotides,and 165 mutation spots (28.5%) were tested in Cytb homological nucleotides. The distance matrix between Guangxi isolate and Hunan isolate was 0.051 and 0.031 for CO1 gene and Cytb gene respectively;while that between Guangxi and Yunnan isolates was 0.158 and 0.405 respectively. Phylogenetic trees constructed by UPGMA and MP took on the similar topo-structure:isolates of Guangxi and Hunan clustered into one group,while the Yunnan isolate exhibited as another group. Conclusion Oncomelania hupensis in Guangxi,Hunan and Yunnan are of relatively rich polymorphism in CO1 and Cytb genes in general.

BACKGROUND:The non-specific immune suppression method is generaly used for treatment of systemic lupus erythematosus, but poor prognosis, such as infection and high recurrence rate, exists.
OBJECTIVE:To evaluate the therapeutic effect of bone marrow mesenchymal stem cel transplantation on systemic lupus erythematosus in mice.
METHODS:Sixteen mice with systemic lupus erythematosus were equivalently randomized into control and experimental groups, or then subjected to passage 3 bone marrow mesenchymal stem cel transplantation or the equal volume of normal saline via the tail vein, respectively. Mouse urine samples were colected to detect urine protein levels by Bradford method. Blood samples from the tip of the mouse tail were extracted to detect serum anti-ds-DNS antibody concentration by radioimmunoassay. Mouse kidney tissues were taken and observed pathohistologicaly through hematoxylin-eosin staining and immunohistochemistry staining under microscope. Flow cytometry was used to detect the expression of CD4+CD25+T cels in the inner canthus blood, fresh spleen and thymus.
RESULTS AND CONCLUSION:Within 10 weeks after cel transplantation, the urine protein levels in the two groups were gradualy increased, and the rising velocity was higher in the control group than in the experimental group. From the 4th to 10th week, the urine protein levels in the experimental group were significantly lower than those in the control group (P < 0.05). In the control group, lymphocyte infiltration was visible in the kidney tissues with a few of plasmocytes, and pathological findings showed the mice presented with interstitial nephritis; in the experimental group, the mice had no pathological changes in the kidney. In the two groups, immune complexes were found in the mesangial area, which showed a patch-like distribution in the control group and a punctate distribution in the experimental group; the relative proportion of the occupied area in the experimental group was significantly lower than that in the control group. The expression level of CD4+CD25+T cels in the blood and thymus were significantly higher in the experimental group than the control group (P < 0.05), and the expression level of CD4+CD25+T cels in the spleen was slightly higher in the experimental group than the control group with no significant difference (P > 0.05). The serum anti-ds-DNA antibody concentration in the experimental group was significantly lower than that in the control group (P < 0.05). Taken together, bone marrow mesenchymal stem cel transplantation can improve the pathological damage in systemic lupus erythematosus mice, and has a certain therapeutic effect on systemic lupus erythematosus.
