Evaluation of efficacy was made on the basis of clinical symptoms, liver function tests, AFP,MRI or CT before and after the treatment.RESULTS: After HIFU treatment, clinical symptoms were relieved in 86.6%(71/82) of patients. The ascites disappeared in 6 patients. ALT (95±44) U/L and AST(114±58) U/L before HIFU treatment were reduced to normal in 83.3%(30/36) and 72.9%(35/48) patients,respectively, after the treatment. AFP was lowered by more than 50% in 65.3%(32/49) patients. After HIFU treatment,MRI or CT findings indicated coagulation necrosis and blood supply reduction or disappearance of tumor in the target region.CONCLUSION: HIFU can efficiently treat the patients with liver cancer. It will offer a significant noninvasive therapy for local treatment of liver tumor.展开更多

Methods： The clinical-pathological data of all 1,335 patients with the International Federation of Gynecology and Obstetrics （FIGO） Ib-[Ia cervical cancer treated with primary radical surgery at the Chinese National Cancer Center between May 2007 and Dec 2013 were retrospectively reviewed. The median follow-up was 70 months. Results： Of all the patients, 61.6% of the cases received adjuvant therapy, with 5-year disease-free survival （DFS） of 92.1% and 5-year overall survival （OS） of 95.0%. In multivariate analysis, differentiation of G3 （P〈0.05）, lymph node metastasis （LNM, P〈0.05） and lymphovascular space invasion （LVSI, P〈0.05） were independent predictors for OS, while LNM （P〈0.05）, deep stroma invasion （DSI, P〈0.05） and LVSI （P〈0.05） were independent factors for DFS. The samples were stratified by histologic type, and cervical squamous cell carcinoma （SCC） was found to share the same independent factors except for differentiation of OS. As to patients with cervical adenocarcinoma/adenosquamons carcinoma （AC/ASC）, differentiation was the independent predictor of OS （P〈0.05）; and LVSI of DFS （P〈0.05）. Of 236 patients with high-risk factors, there was no significant difference in survival between concurrent chemoradiotherapy （CCRT, n=195）, radiotherapy （RT, n=24）, and chemotherapy （CT, n=17）. Among the 190 patients with LNM who underwent CCRT, 124 cases showed improved DFS after sequential CT （P=0.118）, with a recurrence rate decrease of 14%, though the difference was not statistically significant. Patients with single intermediate-risk factors like DSI or LVSI were found to partially benefit from adjuvant therapy, but the difference was not statistically significant. Conclusions： LNM, LVSI, DSI and differentiation were found to be independent prognostic factors for operable cervical cancer. Aggressive postoperative adjuvant therapy based on single risk factors in Chinese National Cancer Center could benefit survival. CCRT＋CT outperformed CCRT in high-risk patients. For patients with single non-high-risk factor, the role of adjuvant therapy needs to be further discussed.展开更多

In industrial 4.0 era, people and technology constant interaction becomes possible. People will be the variable instead of constant in the production process. Each producer is likely to provide creative contributions to the fi nal shape of the individualized product, instead of changing mechanically a few innovators design into product. Therefore, exploring the industrial background of applied talents training mode, cultivating real talents to meet the needs of the intelligent technology become the priority of the development of advanced manufacturing technology under the background of industrial 4.0.展开更多
