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 ) .

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.

Background Myopia is one of the main blinding diseases worldwide.At present,a lot of studies on ocular structure focus on the changes of corneal curvature(CC),central corneal thickness (CCT),anterior chamber depth (ACD),ocular axial length (AL) and choroid and retina,but the research of anterior chamber angle section structure form and ciliary body shape is lack.Objective This study was to measure and analyze the changes of the anterior chamber angle and related tissue structure in myopic eyes.Methods One hundred and forty-nine eyes of 149 subjects were included from May 2008 to May 2010 in Eighth Hospital of Qingdao City with the ages of 18-40years old under the informed consent.The subjects were assigned to the emmetropia group (30 eyes) ([0.02±0.18] D),low myopia group(46 eyes) ([-1.64±0.69] D),moderate myopia group (35 eyes) ([-4.56±0.66] D) and high myopia group (38 eyes) ([-7.04 ± 1.02] D).Conventional indexes including intraocular pressure (IOP),CCT,CC,AL and ACD were measured,and the indexes including chamber angel open distance (AOD),iris thickness (IT1,IT2,IT3),the position of ciliary body such as A-angel,B-angel,trabecular ciliary process distance (TCPD),irisciliary process distance (ICPD) and ciliary body thickness (CBT1,CBT2,CBT3) were measured by ultrasound biomicroscope(UBM).Results The IOP,CC and CCT values showed slight change in different groups without remarkable difference among them (all at P＞0.05).As the increase of myopic degree,AL was extended and ACD was deepened,showing significant differences among the groups (both at P＜0.05).There were no significant differences in IT1,IT2 and IT3 among the four groups (all at P＞0.05).However,the measuring values of angle opening degree (TIA and AOD500),ciliary position (A-angle,B-angle,TCPD,ICPD) and CBT (CBT1,CBT2,CBT3) elevated with the increase of myopic degree (all at P＜0.05).Positive correlations were found between AOD500 and ACD,A-angle,CBT1,CBT2,AL,negative correlations was found between AOD500 and myopic degree (r =0.573,0.513,0.325,0.398,0.542,-0.435,all at P＜0.01);Positive correlations were found between TIA and ACD,A-angle,CBT1,CBT2,AL,negative correlations was found between AOD500 and myopic degree (r =0.573,0.464,0.276,0.410,0.539,-0.435,all at P ＜ 0.01).Conclusions Within certain limits,as the increase of myopic degree,ACD deepens,the anterior chamber angle widens,ciliary process thickens and ciliary body backward shifts.
