Objective To observe the effect of finger-pressing combined with conventional rehabilitation therapy on the recovery of upper limb function after stroke.Methods A total of 60 cerebral stroke patients were randomly divided into an experimental group (n =30) and a control group (n =30).All patients were treated with conventional anti-symptomatic drugs but no anti-spasticity ones.The experimental group was given conventional rehabilitation and finger-pressing therapy,while the control group was given conventional rehabilitation only.Both groups were measured the motor function,using the upper-extremity portion of the Fugl-Meyer Scale,and the mean integrated electromyography (iEMG) output of biceps and flexor carpi radialis after the first finger-pressing treatment and 1 month later,so as to observe the immediate and continuous effects of finger-pressing therapy respectively.Results After the first session of finger-pressing therapy,the average Fugl-Meyer score(FMA) (12.63 ± 4.64) of the experimental group was significantly higher than in a pretest (12.13 ± 4.88) (P ＜ 0.05),while the iEMG of biceps (41.64 ± 9.22) and flexor carpi radialis (37.06 ± 7.02) were lower than before (P ＜ 0.01).One month after the treatment,compared with the control group,the average FMA (25.17 ± 5.93) and iEMG of biceps(34.42 ± 7.55) and flexor carpi radialis sEMG(30.63 ± 5.54) in the experimental group were significantly improved (P ＜ 0.01).Conclusions Finger-pressing therapy has significant and immediate effects in improving the upper extremity spasticity of stroke survivors.Combined with conventional rehabilitation therapy it can effectively reduce the upper extremity spasticity in stroke patients and significantly improve the upper extremity function.The combination is superior to conventional rehabilitation alone.

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.

Objective:To study the role of FDCs-miR-548m-CDK6 axis on clonogenicity in mantle cell lymphoma. Methods:RT-qPCR and Western blot were used respectively to test the expression of miR-548m and CDK6. Bioinformatics assay was applied to predict the targets of miR-548m, and Western Blot was used to test the expression level of CDK6 after miR-548m overexpression or in-hibition. Luciferase report assay was performed to test whether CDK6 was a direct target of miR-548m. Colony forming assay was used to test the colony forming activity in MCL after overexpression of miR-548m or knockdown of CDK6. Results:Cell adhesion to FDCs induced downregulation of miR-548m and CDK6 expression in MCL. Bioinformatics assay revealed that miR-548m could target the 3'-UTR of CDK6 and that a negative correlation exists between the level of miR-548m and the CDK6 expression. Luciferase report as-say confirmed that miR-548m directly targeted 3'-UTR of CDK6. Colony forming assay showed that overexpression of miR-548m or knockdown of CDK6 significantly suppressed MCL colony formation. Conclusion:This study reveals that FDC-enhanced mantle cell lymphoma clonogenicity is mediated by the miR-548m/CDK6 axis.

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.

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 Evaluate the outcome of aortic root reconstruction on the analysis of the risk factors influencing surgical results. Methods Between August 1996 and November 2009, 92 patients(56 men, 36 women) aged from 14 to 77years [mean (44.8 ±1.4) years] with aortic root aneurysm underwent aortic root reconstruction. 72 patients had over moderate aortic valve insufficiency. 47 patients suffered from Marfan syndrome. The aortic pathology was aortic dissection in 45. Bentall technique was used in 59 patients, the button technique in 13, the David I with the Valsalva graft in 6 patients and the aortic valve resuspension in 14 patients. Results The hospital mortality rate was 8.7%. The major complications 31. 7%. 18patients died during the period of follow-up. Late complications among 55 survivors were 12. Univariate predictors of the morbidity were the presence of male, non-Marfan, concomitant procedure, deep hypothermia cardiac arrest, aortic cross clamp time and blood infusion. Risk facts for mortality were emergent or urgent operation, aortic dissection, concomitant procedure, aortic cross clamp time and blood infusion. Multivariate analysis revealed risk factors of concomitant procedure and blood infusion were responsible for both morbidity and mortality. The overall long-term survival rate is (97.1 ±2.0)% at 1-year, (88.1 ±4.7)% at 5-year, (54.0 ±9.2)% at 10-year. The mean for survival time is (9.9 ±0.59) years, 95% confidence interval 8.70 -11.01. Conclusion The aortic root restitution procedures are safe and effective in general. The short and long-term outcome is satisfactory. The button technique is the first choice for reimplantation coronary patch. Valve-sparring aortic root reconstructions show promise in safety and applicability.
