Objective To investigate the relationship of serum cholinesterase(CHE) level with the severity and prognosis in patients with acute cerebral infarction. Methods A total of 325 patients with acute cerebral infarction were recruited as patients group,and another 101 healthy sub?jects were selected as control group. Velocity method was employed to detect the level of serum CHE. Patients with acute cerebral infarction were then divided into different groups according to the infarcts diameter and the modified Rankin scale(mRS)at 1 year post stroke. The collected data were analyzed statistically. Results The level of serum CHE in small and medium area infarction group was higher than control group(P<0.01);the level of serum CHE in large area infarction group was lower than control group(P<0.01);the level of serum CHE was negatively correlated with infarct size,NIHSS and the mRS score(r=-0.302,-0.232,-0.455,P<0.001). The level of CHE,age,NIHSS and infarcts diameter was identified as independent influence factors for prognosis of acute cerebral infarction. Conclusion Early phase of serum CHE level is closely related with the infarct size and illness severity index in patients with acute cerebral infarction,which could be an independent factor affecting the prognosis of cere?bral infarction.

ObjectiveTo explore the effects of small interfering RNA (siRNA) specific to Bcl-2gene on radiosensitivity of esophageal cancer cells. Methods Bcl-2 gene siRNA ( Bcl-2 siRNA ) was induced into esophageal cancer EC9706 cells by lipofectamine.Bcl-2 protein expression and apoptosis of EC9706 cells were detected by flowcytometer. Clone forming assay was used to determine the inhibitory effects of X-ray radiation combined with Bcl-2 siRNA interference. ResultsWhen Bcl-2 siRNA had been induced into EC9706 cells, Bcl-2 protein expression in EC9706 cells was inhibited, and cell apoptosis was increased. Bcl-2 protein expression rates of EC9706 cells induced with Bcl-2 siRNA1, A2, A3 (25.13% ±2. 04% ,38.87% ± 3.34% , 30.55% ± 2. 73% ) were lower than the control group ( 84.28% ± 1. 47% )(t =4. 01,3.04,3.64, P < 0. 05 ). After interference, the apoptosis rate of EC9706 cells ( 33.86% ±1.04% ) was higher than the control group and siRNA negative group (5.51% ±0. 14% and 5.59% ±0. 46% ) (t =6. 55,6. 54,P <0. 01 ). Bcl-2 gene siRNA interference enhanced X-ray inducing apoptosis of EC9706 cells (56.76% ± 1.24% ), which was higher than the radiation alone group ( 24.51% ± 0. 48% )(t =3.59,P < 0. 05 ). The D0, Dq, and SF2 of combined treatment group were much lower than those of irradiation alone group . The sensitization enhancing ratio was 1.32 ( ratio of D0 values ) . Conclusions Bcl-2 gene siRNA could enhance the radiosensitivity of esophageal cancer EC9706 cells and may has a good future in clinical practice.

Objective:Prostate cancer frequently metastasizes to the spine. In this study, we investigate the prognostic factors as-sociated with survival in patients with prostate cancer accompanied by spinal metastases at their preliminary diagnosis. Methods:Clin-ical data of 49 patients who were diagnosed with spinal metastasis from prostate cancer between January 2005 and December 2010 were analyzed. Variables including alkaline phosphatase (ALP), previous skeletal-related event, Gleason score, prostate-specific anti-gen (PSA) nadir, and time to castration resistance were obtained. Moreover, the relationship between these variables and overall sur-vival (OS) was analyzed. Survival analysis was performed by using Kaplan-Meier curves. Furthermore, the differences among the OS rates were assessed by using the log rank test. The variables were statistically significant in the univariate analysis (P<0.05) and were included in the multivariate model. Results:The average follow-up time was 64.1 months among the 49 patients. By the end of the follow-up, 41 of these patients were dead;the mean survival was 27 months. The 1-, 3-, and 5-year survival rate was 81.6%, 40.8%, and 20.4%, respectively. Univariate analysis identified that 6 variables were statistically significant prognostic factors of OS:with or without chemotherapy, ALP, previous skeletal-related event, Gleason score, PSA nadir, and time to castration resistance. The multivari-ate analysis showed that the time to castration resistance of ≥19 months and the addition of chemotherapy after disease progression are independent prognostic factors for a high OS. Conclusion:With or without chemotherapy and the time to castration resistance are the independent prognostic factors associated with survival in patients with prostate cancer accompanied by spinal metastases at first diagnosis.

Objective:To investigate the safety and efficacy of laminectomy combined with vertebroplasty in spinal metastases from rapid-growth tumors. Methods:Clinical data of 23 patients with spinal metastases of lung cancer, who were admitted to the Cancer Hospital from July 2008 to May 2012, were retrospectively analyzed. Thirteen male and ten female patients, with an age range from 40 years to 65 years and a mean age of 51.5, were examined. All patients received posterior laminectomy to relieve spinal cord compression. Afterward, vertebroplasty combined with radiofrequency ablation was conducted, followed by the internal fixation of vertebrae (instrumental fixation). Operation time, blood loss, and bone cement leakage rate were analyzed. One month before and after the operation, pain measurement was conducted using visual analog scale (VAS) and neurologic deficit (spinal cord injury) by Frankel Grade. Functional impairment was classified by Karnofsky performance status (KPS) score. Quality of life was assessed by the European Organization for Research and Treatment questionnaire (EORTC QLQ-C30). Results:The mean operation time was 163±87.36 min. Blood boss was 430±130.35 mL. Bone cement leakage rate was 21.7%. One month before and after surgery, the VAS showed statistical significance (t=25.6, P<0.01). After surgery, 78.3%of all patients exhibited functionally satisfactory Frankel Grade D or E, compared with 43.5%of patients before the operation. KPS score (80 to 100) percentage was 69.6%after surgery compared with 34.8%before surgery. One month after the operation, remission of various degrees was seen in 10 of 18 patients who had sphincteric dysfunction before surgery (55.6%). The EORTC QLQ-C30 score was 85.39±8.99 before and 52.78±15.17 after operation. The quality of life improved significantly (t=11.6, P<0.01). Conclusion:Posterior laminectomy and vertebroplasty combined with radiofrequency ablation for spinal metastases from lung cancer is safe and effective. The treatment can improve pain, function, and life quality of patients with lung cancer spinal metastases.
