Purpose:To investigate the relationship between the expression of NF?B family proteins in ovarian cancer cell lines with chemotherapy resistance of ovarian cell lines. Methods:First, 13 ovarian cancer cell lines were cultured, and then protein was extracted separately from cytoplasm and nucleus. Using Western blotting and MTT chemosensitive testing, the relationship between the expression of NF?B family proteins in ovarian cancer cell lines with chemotherapy resistance of ovarian cell was observed.Results:It was found that the expression of positive rate of P65, P50 and IKB in cytoplasm was 76.9%, 81.8% and 84.6% respectively, and the significant positive expression of P65 and P50 was also found in the nucleus, with a rate of 15.3%, 45.5% respectively. In OV MZ 5 and OV MZ 2774, the expression of P65 was positive and their IC 50 reached a significant value. Conclusions:It was concluded that P50 and P65 affected the growth and development of ovarian cancer cells with the effect of P50 being more obvious. P65 had a close relationship with the chemotherapy resistance of ovarian cancer cells, and thus P65 could be expected to be a new marker in the observation of prognosis.

Respiratory diseases are common in the elderly and often the main causes of death among this population. In addition, it is expected that chronic obstructive pulmonary disease, lower respiratory tract infections, lung cancer, and pulmonary tuberculosis will be listed in the top ten diseases in 2020. Therefore, screening, diagnosis and management of respiratory diseases should be strengthened among the elderly; meanwhile, studies on geriatric respiratory medicine should be further enhanced.

Objective To discuss the correlationship between the diagnosis of surgical pathology and the signs of malignancy which is both displayed by breast conventional mammography and amplificatory mammography with partial compression.Methods 65 cases with breast cancer were examined by both breast conventional mammography and amplificatory mammography with partial compression.The results of the two methods were analyzed.Results In all 65 cases of breast cancer,the comparison between breast conventional mammography and amplificatory mammography with partial compression could provide 16/60 cases in the X-ray signs of malignancy,which were in accordance with pathological examination results,19/41cases in the occurrence of calcification,13/37 cases in ductal calcification,0/4 cases in mixed type calcification,18/46 and 14/59 cases in the occurrence of lobulation and spicule signs.Conclusion Amplificatory mammography with partial compression can provide better insight in breast cancer than conventional mammography,especially in the region of dense shadow,small calcification and dense breast lesions,amplificatory mammography with partial compression can provide higher accuracy in diagnosis,especially for early breast cancer.

To push up the quantity of faculty member in higher medical education,and acclimatize them to the social economic development of 21st century,the significance,instructions,contents,approaches and administrations of continuing education for medical faculty members are discussed.The re-education for medical faculty members should be based on the motivation of activity and spontaneity,and the goal of continuing education should be high quantity,differentiated standard and individuation.

Objective To evaluate the outcomes of open reduction and internal fixation of complex tibial plateau fractures with improved three combined approaches.Methods In the period from July 2014 to February 2016,7 complex tibial plateau fractures underwent surgical treatment.These patients included 5 male and 2 female,aged from 24 to 68 years old (average,39.7± 15.3 years).According to Schatzker classification,they were all of type V.And all of type 41B-3.1 by AO/OTA classification.All these fractures were exposed and reduction via three combined approaches.First let the patients lied in lateral prone position,expose the anterolateral and the posterolateral of the tibia1 plateau,and fix the fractures of the posterior in the posterolateral approach,then fix the fractures of the lateral in the anterolateral approach.Then turn the patients to supine position,fix the fractures of the medial in the anteromedial incision.All patients received regular reexamination.The knee function was evaluated at the final follow-up using The Hospital for Special Surgery (HSS) score,the activity of the knee was evaluated by Lysholm score,and the stability of the knee was checked by Lachmantest and Pivot-shift test.The tibial plateau angle,the posterior slope angle and Rasmussen X-ray score were assessed on the X-ray films.Results The average time of operation is (3.3±0.9) h,and the hemorrhage volume in operation was (341± 106) ml for the 7 patients.The wounds of 6 patients healed by (11.8± 1.3) days,while the wound of the rest one of them occurred fat liquefaction after operation who is very fat (BMI ＞ 30) and suffered from diabetes.His wound healed by 21 days.These patients obtained follow-ups of 8 to 14 months (average,11.4±2.8 months).The average full weight-bearing time was 2-3 months (average,2.5±0.4 months).The fractures healed after 8 to 16 weeks (average,11.1 ±2.8 weeks).No displacement of the fractures or breakage of the implants occurred in our series.Nobody has activity limitation of the knee or pain because of the implant,and no never symptoms were noted postoperatively,so we would not take out the implant for these patients.The mean HSS score was 93.1±4.8 (range,from 85 to 100) at the final follow-up,and the excellent rate is 100％.The Lysholm score was 97.1±3.6 (range,from 90 to 100) at the final follow-up.The Lachman test and the Pivot-shift test were negative in our patients,and the mean knee flexion was 128.6±12.8°(range,from 105°to 140°).The fractures were all anatomical reduction by the X-ray after operation,and there had being no displacement of the fractures or breakage of the implants occurred during the follow-up period.The mean posterior slope angle was 8.29±2.87° (range,from 4 °to 12°),which was 8.71±2.63° (range,from 5 °to 14°) 6months after operation.The mean tibial plateau angle was 86.00± 1.41° (range,from 84 °to 88°),which was 86.43± 1.62° (range,from 84 °to 89°) 6 months after operation.The mean Rasmussen X-ray score was 16.86±1.57 (range,from 14 to 18),which was 16.57±1.51 (range,from 14 to 18) 6 months after operation,and the excellent rate are 100％.Conclusion For the complex tibial plateau fractures which simultaneous involved the medial,the lateral and the posterior,the improved three combined approaches showed the advantages of the convenient operation,the satisfactory results of reduction and fixation,and the less trauma and secondary damage,and could be worth for clinic.
