This paper collected the traditional Chinese medicine (TCM) prescriptions of osteoporosis and osteoarthritis from CNKI to set up database and used TCM inheritance system to analyze the composing principles in prescriptions. We collected 103 and 106 prescriptions for osteoporosis and osteoarthritis respectively, then analyzed inherent principles between herbs in prescriptions by using the TCM inheritance system, and obtained the frequency of each herb, and drug combinations of two diseases' prescriptions. The result showed that the principles in TCM prescriptions of osteoporosis and osteoarthritis are similarities, buch as tonifying kidney and invigorating the circulation of blood, but differences of the specific drugs. That is to say, tonifying kidney is the main method of osteoporosis treatment, however, invigorating the circulation of blood is the main method of osteoarthritis treatment.

Objective To investigate incidence,risk factors and the prevention strategy of local recurrence 6 months after surgery for metastatic bone tumors.Methods Data of 797 patients who had undergone operations for metastatic bone tumors from March 1997 to March 2012 were retrospectively analyzed.Sixty-three patients (7.9％) who had local recurrence 6 months after operation were enrolled in the recurrence group,including 40 males and 23 females,and the average age at the time of operation was 55.21 years.Seven hundred thirty-four patients were enrolled in the non-recurrence group,including 432 males and 302 females,with an average age of 56.49 years.The risk factors for local recurrence 6 months after operation for metastatic bone tumors were statistically analyzed.Results The statistical analysis showed the risk factors for local tumor recurrence 6 months after surgery for metastatic bone tumors included preoperative general condition (10.9％ vs 6.2％),the rate of progress of the primary tumor (10.1％ vs 6.1％),site of bone metastasis (9.1％ vs 3.9％),surgical method (11.4％ vs 6.4％),whether local radiotherapy was performed preoperatively (28.0％ vs 6.6％),whether local radiotherapy was performed postoperatively (8.7％ vs 2.8％),whether sensitive systemic therapy was performed preoperatively (12.2％ vs 6.1％),whether sensitive systemic therapy was performed postoperatively (10.3％ vs 5.6％) and whether local therapy was performed in primary tumor site (10.1％ vs 5.8％).Multivariate analysis showed the independent risk factors included preoperative general condition (OR=0.534),rate of progress of the primary tumor (OR=2.164),site of bone metastasis (OR=2.906),whether local radiotherapy was performed preoperatively (OR=3.184),whether sensitive systemic therapy was performed preoperatively (OR=2.344) and whether sensitive systemic therapy was performed postoperatively (OR =0.468).Conclusion When the patients has following conditions:poor preoperative general condition,fast progressive primary tumor,metastatic tumor in the axial skeleton,application of local radiotherapy preoperatively,and application of sensitive systemic therapy,the surgical treatment should be chosen cautiously.

Objective To investigate relationship between microRNA-200c and ZEB1 in cervical epithelial mesenchymal transition factor. Methods 50 cases diagnosed with cervical cancer whose tumor tissue were taken to be the experiment group.50 cases diagnosed with uterine myoma whose normal tissue were taken to be the control group.ZEB1 and microRNA-200c of uterine tissue were were detected.Results The average level of ZEB1 in the experimental group was significantly higher than that of the control group (P<0.05), and in cervical cancer, lymph node metastasis and the depth of myometrial invasion had statistically significant (P<0.05).In experimental group, microRNA-200c average was lower than control group (P<0.05), and in cervical cancer, different pathological grade group, lymph node metastasis and deep muscular layer infiltration had statistically significant(P<0.05).In experimental group, ZEB1 and microRNA-200c showed negative correlation(r =-0.270 P =0.001).Conclusion The expression level of ZEB1 in cervical cancer is higher, and the expression level of microRNA-200c in cervical cancer is lower, suggesting that the two factors may play an important role in the invasion and metastasis of cervical cancer.The correlation between the two factors suggests that microRNA-200c may be involved in the process of cervical cancer by ZEB1.

Objective:To generate rabbit polyclonal antibody against human Argonaute2 (Ago2) protein and to identify its functional characterization for determination of differential expression and cellular localization of Ago2 protein in various cell lines.Methods:DNAstar software was applied for searching the high antigenicity region of Ago2 gene sequence termed k-Ago2.Prokaryotic expressing plasmid was constructed and transformed to E.coli BL21 (DE3) to induce expression by IPTG.The fusion protein was injected into rabbits subcutaneously to produce polyclonal antibodies after purification by gel regaining.ELISA was operated to detect antibody titer.Western blot was used to identify the specificity and sensitivity of the antibodies and detect the differential expression of Ago2 protein in various cell lines.Meanwhile,immunofluorescence experiments were arranged to show cellular localization of Ago2 protein.Results:The prokaryotic expressing plasmid was constructed correctly.K-Ago2 protein was expressed and purified,and then rabbit polyclonal antibodies against Ago2 were generated after immunization with k-Ago2 protein.The titer detected by ELISA was 1∶19 000.Western blot results demonstrated the high specificity of the antibodies.Finally,we successfully observed the differential expression and cellular localization of Ago2 protein in various cell lines.Conclusion:The polyclonal antibody against Ago2 protein has been achieved successfully.It will be propitious for the intensive study of the RNAi mechanism and even profound clinical application.

Objective To investigate how many probably benign lesions on ultrasound(US) fulfilled the published criteria and to evaluate how clinical and personal factors influenced the categorization of breast lesions.Methods A total of 487 lesions in 487 women with more than 12 months follow-up after the initial category 3 assessment on US were included.The initial US images were retrospectively reviewed according to previously published criteria,and evaluated several factors that could influence the characterization of breast lesions in clinical practice such as age,multiplicity,palpability,radiologist 's experience,and lesion size.Results Of 487 lesions,479 (98.36%) were benign and 8 (1.64%) were malignant.Of 487 lesions,203(41.68%) including 8 malignancies were reassessed as category 4.If strict criteria had been applied at initial US examination,the positive biopsy rate would have been only 3.94% (8/203) and 96.06% (195 of 203) biopsies would have been unnecessary.Lesions in women 40 years or older and multiple lesions were more frequently reassessed as category 4 (P = 0.008 and P = 0.006,respectively).The presence of palpability,lesion size,and the radiologist 's experience did not significantly influence the categorization of breast lesions on US.Of 487 probably benign lesions,41.68 % could be classified as category 4 lesions when strict criteria were applied in initial practice.Conclusions The multiplicity of the lesion and the patient 's age were found to have a significant influence on the classifcation of probably benign solid masses.

Objective To explore the optimal protocol of lower-extremity contrast-enhanced MRA (CE-MRA) in the evaluation of diabetic foot.Methods Twenty eight healthy volunteers were scanned by CE-MRA in crus twice with parellel imaging factor (PIF) of 3 or 4.The signal-to-noise ratio (SNR),contrast-to-noise ratio (CNR) and image quality of popliteal artery,posterior tibial artery,anterior tibial artery and peroneal artery were compared.Twenty patients with diabetic foot underwent CE-MRA by both of protocol 1 and 2 in leg,crus and foot.Protocol 1 was the traditional Care-bolus protocol and protocol 2 was the optimized K-space center filling delay-time protocol.The difference of two protocols in venous aliasing and in display of femoral artery,popliteal artery,posterior tibial artery,anterior tibial artery,peroneal artery,dorsalis pedis artery,medial plantar artery and lateral plantar artery were compared.The SNR,CNR of two different PIF sequences were compared by paired t test,and the display of artery of crus was compared by Wilcoxon.The display of vessels and venous aliasing of 2 protocols of diabetic foot patients were compared by Wilcoxon.Results In the images of healthy volunteers with PIF of 3,the SNR were 267±84,174±51,147±42;and the CNR were 232 ±83,139±51,108±39 at popliteal artery,posterior tibial artery and peroneal artery.However,in the images with PIF of 4,the SNR were 239±73,157±53,132±35;and CNR were 206±71,124±50,103±33,respectively.Both the SNR and CNR were higher in the former than in the latter(t values were 2.31 to 4.11,P＜0.05).There was no significant difference in the vessel display between the different PIF volunteers (P＞0.05).In the protocol 1 of patients with diabetic foot,the display of popliteal artery,posterior tibial artery,anterior tibial artery,peroneal artery,dorsalis pedis artery,medial plantar artery and lateral plantar artery,the venous aliasing in crus and foot were 3.40±0.82,2.70±0.80,2.50±1.00,2.20±0.77,2.30±0.92,2.15± 1.04,1.45±0.60,2.20± 1.01,2.20± 1.06.And in the protocol 2,they were 3.85±0.37,3.55± 0.69,3.30±0.92,2.90±0.79,3.30±0.92,3.25±0.79,1.95±1.10,3.70±0.47,3.65±0.49,respectively(P＜0.05).All of these parameters of protocol 2 were superior to protocol 1.Conclusion Using a higher PIF properly,setting the personalized K-space center filling delay-time can contribute to improving the image quality of whole lower-extremity MRA in patients with diabetic foot.
