Objective: This study aims to investigate the correlation between the expression of FoxP3, TGF-β1, and epitheli-al-mesenchymal transition (EMT) in breast cancer and to determine the clinical significance of FoxP3. Methods: The expression of FoxP3, TGF-β1, E-Cadherin, N-Cadherin, Vimentin, and Fibronectin protein were detected in the cancer cells of 74 cases with breast carcinoma via immunohistochemistry. The correlation of FoxP3 protein with clinico-pathologic features of breast carcinoma and the re-lationships among the expressions of FoxP3, TGF-β1, and epithelial-mesenchymal transition (EMT) were analyzed. Results:The ex-pression rates of FoxP3, TGF-β1, and EMT are 36.5%(27/74), 39.2%(29/74), and 40.5%(30/74), respectively. The FoxP3 protein ex-pression in breast cancer is correlated with lymph node metastasis (P<0.05) but not with other clinico-pathological features (P>0.05). The expression of FoxP3 is also correlated with the expression of TGF-β1. Furthermore, TGF-β1 can induce EMT (P<0.05). Conclu-sion:The expression of FoxP3 is correlated with lymph node metastasis and EMT in breast cancer. Therefore, FoxP3 may be a marker for predicting metastasis.

One hundred and sixteen patients with lower limb fracture were screened by Doppler ultrasound for deep vein thrombosis(DVT) of bilateral lower extremities within the first 72 h, d7 and d21 after fracture. Results showed that DVT was detected in 31 (26. 7% ) out of 116 cases within 72 h; at d7 and d21 DVT was detected in 3 and 1 patient respectively with a cumulated DVT rate of 30. 2% in 3 weeks.Serial Doppler ultrasonography is of value in screening for DVT of the lower extremities in patients with lower limb fracture at early stage.

Objective To construct a luciferase reporter plasmid containing interferon regulatory factor 3(IRF-3)human gene promoter and to evaluate promoter activity in human embryonic kidney(HEK)-293 cells.Methods The 1 000 bp fragment was amplified by PCR with human genomic DNA as a template and was directionally cloned into pGL3-basic multiple cloning sites to construct the luciferase repor-ter plasmid pGL3-pIRF-3.Transfection of HEK-293 cells with the promoter-driven lucife-rase construct was performed to induce lucife-rase gene expression and calculate the relative luciferase activity unit(RLU).Promoter sequence of 1 000 bp upstream of transcription initiation site of IRF-3 was analyzed by using Promoter 2.0 Prediction software.Results DNA sequencing and restriction endonuclease analysis verified the successful construction of the plasmid pGL3-pIRF-3.This IRF-3 promoter exhibited a strong promoter activity with an increase of 42.2-fold of RLU in HEK-293 cells when compared with pGL-3 basic vector.The transfection experiment confirmed that the levels of its activation were significantly higher than that in controls in HEK-293 cells.Function analysis of IRF-3 promoter disclosed seve-ral GATA-1 and specific protein 1(Sp1) sites and E2F in minimal promoter region.Conclusion The plasmid pGL3-pIRF-3 promoter is successfully constructed and has a strong basal promoter activity in HEK-293 cells.

OBJECTIVETo analyze the data of angle variation on traction based on a finite element model of complete cervical spine with straight physiological curvature, and try to give experimental reference and suggestion in treating cervical spondylosis.
METHODSA 43-year-old female patient with straight cervical spine was chosen and the CT scan data were collected. By using specially designed modeling system, a high quality finite element model of complete cervical spine with straight physiological curvature is generated,which included ligament and muscle according to anatomy. After the model was confirmed, traction was loaded with angle 0 degree, anterior 5 degrees, 10 degrees, 15 degrees, 20 degrees, 25 degrees, to observe the data of distance change on between adjacent intervertebral foramen, processus articularis, uncovertedral joint, intervertebral discs, and stress of anulus fibrosus and nucleus pulposus.
RESULTSWhen the angle was 0 degrees-15 degrees, the distance between intervertebral foramen, Luschka joint and processus articularis posterioris was enlarged, the tensile stress was adequate and compressive stress was small. It met the clinical requests.
CONCLUSION0 degree-15 degrees anterior position is suggested for the treatment of cervical spondylosis.

OBJECTIVETo explore the effect of combination of Epimedii Folium and Ligustri Lucidi Fructus on osteoporosis rats induced by retinoic acid.
METHODSixty three-month-old male Wistar rats were randomly divided into the normal control group, the model group, the Epimedii Folium group, the Ligustri Lucidi Fructus group, the combination group of Epimedii Folium and Ligustri Lucidi Fructus and the raloxifene group. The osteoporosis model was established through oral administration with retinoic acid for two weeks. Meanwhile, all of treatment groups were administered with corresponding drugs for three weeks. The contents of serum calcium (Ca), phosphorus (P), alkaline phosphatase (AKP) and tartrate-resistant acid phosphatase (StrACP) were detected, and the pathomorphological changes of femurs were observed.
RESULTThe model control group showed much lower contents of serum Ca and P than the normal control group, but with significantly higher AKP and StrACP activity than the normal control group. The femoral head area showed reduced, narrow and sparse trabecular bones, with typical osteoporosis-like changes. Compared with the model control group, all of treated groups showed significant increase in Ca and P contents in serum, and down-regulate AKP and StrACP levels, while trabecular bones became more and wider, and densely interweaved as a reticular formation. Among them, the combination group showed the most significant effect.
CONCLUSIONEpimedii Folium and Ligustri Lucidi Fructus could effectively correct the abnormal bone metabolism and improve pathological conditions of bone tissues, so as to show the anti-osteoporosis effect. The combined application of the two drugs showed a better efficacy.
