Objective To explore the safety, efficacy and 1-year follow-up outcome of radiofrequency ablation combined with magnetic navigation assistance system in elderly patients with atrioventricular node reentrant tachycardia (AVNRT). Methods Forty cases of patients with AVNRT identified by the electrophysiological test were enrolled in the study. Twenty cases were ablated with magnetic navigation system. The other 20 cases underwent the conventional catheters operation. With the cardiodrive, the 8 Frablation magnetic Helios I (Stereotaxis Inc, USA) was advanced to the Koch triangle area from the inferior caval vein (IVC). With the assistance of magnetic navigation (AXIOM Artis, Siemens, Germany), the direction of tip and the advancement or retraction of the catheters were regulated. The success rate, the time of procedure, the fluoroscopy time and the 1-year follow-up outcome were analyzed, and the complications of procedure were recorded. Results Forty cases with AVNRT underwent radiofrequency ablation successfully. In magnetic navigation group, 19/20 cases underwent magnetic catheter operation. The cases who failed to finish magnetic catheter operation underwent successfully conventional catheter operation. There was no perforation complication and no significant statistic difference in the success rate between two groups. No recurring case was found in the two groups 1 year later. The total of fluoroscopy time in magnetic navigation group was more than that in standard ablation group [(16.4±2.7) min vs. (11.1±1.0)rain, P<0.01], but the decreasing trend of fluoroscopy time in magnetic navigation group was showed. The operator's fluoroscopy time in magnetic navigation group was obviously less than that in standard ablation group [(4.5±0.6) min vs. (11.1±1.0) min, P<0.01]. Conclusions The radiofrequeney ablation combining with magnetic navigation system has the similar safety and efficacy to the conventional ablation in elderly patients with AVNRT, but the operator's fluoroscopy time was significantly decreased.

Purpose To investigate estrogen receptor ( ER ) , progesterone receptor ( PR ) expression in PTEN-deficient endometrial carcinoma and to analysis the relationship of PTEN, ER and PR protein expression with histological grade, pathological staging and muscle invasive. Methods Immunohistochemistry EnVision was used to detect the expression of PTEN, ER and PR protein in 100 ca-ses of endometrial carcinoma. Results The rate of PTEN-deficient endometrial carcinoma was 52. 0% (52/100). The expression rate of ER, PR protein on PTEN-deficient endometrial carcinoma was 15. 4% (8/52), 19. 2% (10/52), respectively. And the expression rate of ER, PR protein on PTEN over-expression endometrial carcinoma was 72. 7% (8/11), 63. 6% (7/11), respectively. The rate of PTEN, ER and PR expression types shown PTEN-ER-PR- was 42. 0% (42/100), which was higher than other types (P <0. 05). Different PTEN, ER and PR expression types were well correlated with histological grade and pathological staging (P<0. 05), but not with muscle invasive. Conclusion Combined detection of PTEN, ER and PR may have an important reference value for prog-nosis and treatment of endometrial carcinoma.

Objective To stduy the expression of PTEN ,P27 and BAG-1 in endometrial carcinoma ,and to analysis the clinical significance .Methods The expression of PTEN ,P27 and BAG-1 in 102 cases of endometrial carcinoma ,90 cases of endometrial hy-perplasia and 44 cases of normal endometrium tissue were detected by immunohistochemistry .Results PTEN and P27 in endome-trial carcinoma and hyperplasia tissue showed lower expression ,BAG-1 showed high expression in them .The expression of PTEN and BAG-1 were well correlated to histology degree and muscular infiltration .BAG-1 expression also had a well correlated to clinical stage .In this study ,we had not find a correlated between the expression of P27 and clinical and pathology characteristic of patien . PTEN expression had a Pearson relevance to P27 or BAG-1 expression ,but there was no correlation between P27 and BAG-1 .Con-clusion PTEN and P27 in endometrial carcinoma and hyperplasia tissue showed lower expression ,BAG-1 showed high expression in them .PTEN ,P27 and BAG-1 might play a role in the development of endometrial cancer .

Objective:
To investigate the efficacy and safety of IA regimen which contains idarubicin (IDA) 8 mg/m2, 10 mg/m2 or 12 mg/m2 as induction chemotherapy for adult patients with de-novo acute myeloid leukemia (AML) .
Methods:
A total of 1 215 newly diagnosed adult AML patients, ranging from May 2011 to March 2015 in the First Affiliated Hospital of Soochow University and other 36 clinical blood centers in China were enrolled in the multicenter, single-blind, non-randomized, clinical controlled study. To compare the response rate of complete remission (CR) , adverse events between different dose idarubicin combined with cytarabine (100 mg/m2) as induction chemotherapy in newly diagnosed patients of adult AML.
Results:
Of 1 207 evaluable AML patients were assigned to this analysis of CR rate. The CR rates of IDA 8 mg/m2 group, IDA 10 mg/m2 group and IDA 12 mg/m2 group were 73.6% (215/292) , 84.1% (662/787) and 86.7% (111/128) , respectively (
