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.

Objective To investigate the effect of siRNA targeted against Bcl-xl on cell proliferation of rheumatoid arthritis (RA) and the effect on expres-ion of apoptosis relevant factors Bcl-xl,Bax,Caspase-3.Methods Human RA synovial cells were cultured and passed by tissue block collagenase digestion method.The siRNA plasmid targeting Bcl-xl gene was constructed by Bcl-xl cDNA sequence provided by gene banks,while single missense sequences were used as negative controls.LipofectamineTM 2000 was used to transfect synovial cells.The effect of Bcl-xl silencing on proliferation of synovial cells was evaluated by MTT at 24,48,72 hours after transfection.The expressions of Bcl-xl,Bax,Caspase-3 protein,synovial apoptosisrelated factors were determined by Western blotting after transfected at different time points.The average of multiple-sample average was analyzed by single-factor x2 test or LSD-t and Tamhane's T2 test was used for twotwo comparison.Results MTT result s showed that RNA interference that specifically silent Bcl-xl could obviously suppress the proliferation of sliding film cells,which was most eveident at 48 hours.This inhibition was gradually weakened with prolonged time,but when compared was the control group,differences was significant (P＜0.05).Western blotting results displayed that when compared to the control group,Bcl-xl protein expression obviously declined after transfection P＜0.01,which was the least at 48 h time point.Bax,Caspase3 protein expression were obviously increased when compared to the coutrol group.Conclusion The expression of Bcl-xl,a RA synovial cell anti-apoptotic factor,is significantly reduced by specific RNA interference silencing Bcl-xl,which may play an important role in inhibiting the excessive proliferation of synovial cells.

BACKGROUND:The finite element analysis method is more accurate and fast to construct the three-dimensional model of the human skeleton and design the bone surgical medical instrument.
OBJECTIVE:To establish locking plate model according to the clavicle model, analyze and evaluate stress distribution of locking plate of the finite element model under bending and torsion conditions.
METHODS:Chest scan was carried out in a healthy young adult male by adopting 64-row spiral CT and his two-dimensional image data were gotten. The obtained data were analyzed with Mimics 10.0 software to establish the three-dimensional clavicle finite element model. The clavicle locking fixation plate model was established by applying the UG software. The locking fixation plate was evaluated by utilizing the abaqus software when the plate was bent while down to give force of 200 N, and twisted while 200 N?mm, to simulate the force and analyze the stress distribution of the locking plate.
RESULTS AND CONCLUSION:Based on the original image parameters provided by CT, this experiment produced a three-dimensional model of the clavical titanium plate which fitted better to bones. This model can obtain a single individual, personalized plate by three-dimensional printing technology. The finite element analysis basical y can simulate the actual stress of the plate. For straight plate and“S”-shape plate, in lateral bending and axial torsion loads, the maximum stress distribution of the seven-hole titanium plate is located in the center of the center hole. During actual surgical procedures, clavicle fracture fragments and middle locking hole had stress superposition. If the titanium plate can avoid the stress concentration, it can effectively avoid the occurrence of the broken plate after implantation, provide theoretical guidance for clinical practice, and provide reference and technical route for biomechanical analysis of other types of titanium plate.

OBJECTIVE:To provide reference for clinical use and revision of drug instruction manual. METHODS:The ambi-guity in drug instructions manual was summarized and countermeasures of revision were presented based on the practical clinical conditions. RESULTS & CONCLUSIONS:The problems of drug instruction manual that may mislead the patients and medical per-sonnel were as follows as controversial main contents,unclear descriptions of instruction,unfocused contents or without key points,one instruction for multiple drugs,obvious or inaccurate translations,words without popularity and standardization and wrong sentence division or non-standard typesetting. It is suggested that the manufacturers should attach highly importance to the re-vision of drug instruction manual;the revisers should understand the meaning of drugs instruction manual and know the subjects;the premarketing instructions should be tested and investigated by necessary persons;the major and cultural quality of revisers should be improved;the approval monitoring should be strengthened and the feedback mechanism should be established to further improve the instructions,guide the medical staff and patients with accurate use of drugs and ensure the safe drug use of patients.

Objective:This study aims to investigate the correlation and significance between the expression of P53 and epitheli-al-mesenchymal transition (EMT) in breast cancer. Methods:The expression patterns of P53, Twist, Snail, E-cadherin, N-cadherin, Vi-mentin, and Fibronectin protein were detected via immunohistochemistry in 63 cases with breast carcinoma. The correlation of P53 pro-tein with clinicopathologic features and survival of breast carcinoma, as well as the relationship between the expression of P53 and EMT, was analyzed. Results:The expression rates of P53, Twist, Snail, and EMT are 44.4%(28/63), 54.0%(34/63), 68.3%(43/63), and 41.3%(26/63), respectively. The P53 protein expression is correlated with tumor grade (P<0.05) but not with other clinicopatholog-ic features (P>0.05). The expression of P53 is also correlated with the expression of Twist and Snail, which are associated with EMT (P<0.05). Multivariate survival analysis reveals that lymph node metastasis, P53, and EMT are independent prognostic factors. Conclu-sion:The expression of P53 is correlated with tumor grade and EMT in breast cancer, which can be used as an independent prognostic factor. Therefore, P53 may be an effective target for breast cancer therapy.
