Objective To investigate the diagnostic value of volume imaging for breast assessment (VIBRANT) dynamic enhanced MR for benign and malignant breast mass.Methods Ninety-eight patients with breast mass underwent both bilateral molybdenum target radiography and VIBRANT dynamic enhanced MR examination.The sensitivity,specificity,positive predictive value,negative predictive value and diagnosis accuracy between two methods were compared.Results There were 113 lesions including 65 lesions in 57 malignant cases and 48 lesions in 41 benign cases.The sensitivity,specificity,positive predictive value and negative predictive value of molybdenum target radiography were 67.69％ (44/65),68.75％ (33/48),74.58％ (44/59) and 61.11％ (33/54),respectively.The values of VIBRANT dynamic enhanced MR were 84.62％ ( 55/65 ),89.58％ (43/48),91.67％ (55/60) and 81.13％ (43/53),respectively.The difference of the diagnosis accuracy between two methods had statistical significance (P ＜0.05).Conclusion The diagnostic value of VIBRANT dynamic enhanced MR for benign and malignant breast mass is higher than molybdenum target radiography.

The authors first expound the connotations and origin of the legal person management structure and then discuss the following issues: the dual relation of agency by agreement characteristic of medical institutions, the need to take management structure as the priority of hospital reform in delegating powers to lower levels, the primary strategies and major means of the legal person management structure of corporations, and questions related to the management structure of the medical industry abroad: who should become the agent of the patient, how to unify the interests of the agent and the consignor by means of reasonable remuneration designs, etc. Finally the authors give an account of the inspiration that can be drawn from the legal person management structure to the public hospital property right system reform in China.

Objective To investigate the effect of activated PI3-K on epithelial-mesenchymal transdifferentiation of HKCs induced by transforming growth factor?1 (TGF-?1). Methods The human kidney proximal tubular epithelial cells (HKCs) cultured on plastic plates were divided into following groups: cultured with free serum medium (FSM); culture in the different concentrations of TGF-?1; cultured in the presence of recombinant human TGF-?1 and PI3-K inhibitor Wortmannin. The expression of total and phosphor-Akt (t-Akt and p-Akt) was assessed at different time points by Western blot,? smooth muscle actin(?-SMA) and E-cadherin were detected by Western blot. Results A marked increase in p-Akt was seen in HKC at 1h after being induced by TGF-?1, and its protein level was enhanced in a TGF-?1 concentration-dependent manner. Protein level of ?-SMA was increased markedly at 48 hours after the treatment of TGF-?1, but protein level of E-cadherin was decreased 48 hours after treatment of TGF-?1. Addition of PI3-K inhibitor Wortmannin (10nmol/L) largely abrogated the effect of TGF-?1. Wortmannin was showed to down-regulate ?-SMA and p-Akt expression and in response to TGF-?1 and up-regulate E-cadherin expression. Conclusion PI3-K was activated in epithelial-mesenchymal trans-differentiation of HKCs promoted by TGF-?1, and PI3-K inhibitor Wortmannin can significantly inhibit TGF-?1 induction of EMT.

Objective: To investigate whether the signaling of PI3K/Akt is involved in epithelial-mesenchymal transdifferentiation (EMT) of human kidney tubular epithelial cell (HKC) promoted by transforming growth factor (TGF)-?_1. Methods: the HKC was cultured on plastic plates in the presence or absence of recombinant human TGF-?_1 and PI3K inhibitor wortmannin. The expression of total- and phosphor-Akt and ?-SMA was assessed at different time point by Western blot. Results: In HKC, basic level of p-Akt, ?-SMA expression was found in the normal condition. Profound increase of p-Akt was seen at 0.5 h after induction of 10 ng/ml TGF-?_1 in HKC.?-SMA increased markedly at 48 h after the treatment of TGF-?_1. Adding PI3K inhibitor wortmannin (10 nmol/L) largely abrogated the effect of TGF-?_1. Wortmannin was shown to down-regulate ?-SMA and p-Akt expression in response to TGF-?_1. Conlusion: PI3K/Akt is a downstream mediator in EMT of HKC promoted by TGF-?_1, and PI3K inhibitor wortmannin can significantly inhibit EMT induced by TGF-?_1.

BACKGROUND: The renal transplanted recipients were in poor immunosuppressive state. Compared to common person, the bladder transitional carcinoma in recipients was aggressive and easy to recurrence. Looking for a more effective therapy method to decrease the recurrence of recipients' bladder transitional carcinoma is the hot and difficult problem in clinical study.OBJECTIVE: To analyze the efficacy and safety of submucosal injection epirubicin following transurethral resection of bladder tumor (TUR-Bt) to treat the recurrence of bladder transitional cell carcinoma in renal transplantation recipients.METHODS: Totally 9 renal transplantation recipients with transitional cell carcinoma of bladder were retrospectively studied. The patients' periods without cancer, the frequency of recurrence within one year, the rates of side effect, the changes of tumor grading following recurrence and allograff function were recorded when the routine method and submucosal injection epirubicin following TUR-Bt were used in different period respectively.RESULTS AND CONCLUSION: Submucosal injection epirubicin following transurethral resection of bladder tumor was safe and effective to treat bladder transitional cell carcinoma recurrence in renal transplantation recipients. Compared to the routine perfusion, periods without cancer and the frequency of recurrence within 1 year were significantly decreased, which can elevate recipients life quality and long-term survival rates.

Objective To investigate the security and efficacy in the elderly patients with acute myeloid leukemia (AML) treated by decitabine based regimen. Methods A retrospective analysis was carried out on 12 elderly patients with AML who were treated by decitabine alone or with low-dose chemotherapy in Beijing Luhe Hospital, Capital Medical University from June 2014 to December 2015. Results There were 6 patients of complete remission (CR), 5 patients of partial remission (PR), 1 patient of none remission (NR) after one course of chemotherapy. 1 case of 6 CR patients relapsed after 6 cycles of chemotherapy , others remained CR during the follow-up . Among 5 PR patients , 2 cases achieved CR , 1 patient relapsed after 2 cycles of chemotherapy and 2 patients relapsed after 3 cycles of chemotherapy. 1 patient remained NR after 2 cycles of chemotherapy and died of severe pulmonary infection. 3 of 4 complex karyotype patients had poor efficiency, and only 1 patient achieved CR but relapsed eventually. 7 patients achieved CR in patients with +8, -X or normal karyotype in the near future. The main adverse effects were bone marrow suppression and infection. All patients could tolerate. Conclusion Elderly patients with primary AML treated by decitabine alone or with low-dose chemotherapy show good effects, well tolerance and high safety, which could serve as the front-line treatment.

Statins are a class of hydroxymethylglutaryl-CoA (HMG-CoA) reductase inhibitors, which are pervasively used to reduce blood cholesterol concentration in hypercholesterolemic patients and prevent cardiovascular diseases in clinic, duo to excellent drug efficiency and good safety. In recent years, increasing evidences have demonstrated that statins have potential anti-tumor effect through inhibiting cancer cells growth, invasion, metastasis, preventing angiogenesis, promoting cancer cells apoptosis and synergetically enhancing the effect of radiotherapy and chemotherapy. However, there are no domestic reports about statins' effect on endometrial carcinoma, additionally, conclusions of related foreign studies are inconsistent. This review summarized the effect of statins on endometrial carcinoma.
