Objective To establish a cell level-based negative enrichmen technique to detect circulating tumor cells (CTCs) in the peripheral blood of patients with epithelial ovarian cancer.Methods The colon cancer SKOV-3 cells were mixed with 2 ml whole blood from healthy donors at different ratio.Quantification of CTCs was performed using immunomagnetic bead based negative enrichment combined with immunofluorescence antibody method.The method was evaluated the recovery rate of target cells,Samples of 32 patients with ovarian cancer and 10 controls were assayed for CTCs detection by above method.Results ①The recovery rate was ranging from 64% ~80% by spiking varying numbers of SKOV-3 into 2 ml blood samples of healthy volunteers.Regression analysis of number of recovered SKOV-3 cells yielded a regression equation of Y=0.782X-1.408 and a coefficient of determination of R2 =0.998.②Did not detect CK8/18-+ circulating tumor cells in 10 controls,and CK8/18+ circulating tumor cells in 18 cases of 32 Patients with ovarian cancer.The positive rate of CK 8/18 + circulating tumor cells was significantly differences between the two groups (x2 =7.681,P<0.01).③The presence ofCTCs was significantly correlated with distant metastasis (x2 =5.776,P<0.05).Conclusion The method of immunomagnetic bead based negative enrichment combined with immunofluorescence antibody technique for CTCs detection in peripheral blood of patients with ovarian cancer has a clinical value of application and extension.

Objective To study the metabolic change of proton magnetic resonance spectroscopy (1 H-MRS)in the visual cortex and optic radiation region of patients with diabetic retinopathy (DR).Methods 1H-MRS was performed in 20 patients with DR and 20 healthy volunteers on GE 1.5 T MR system respectively.Metabolic peaks of N-acetylasparte(NAA),creatine(Cr,in 3.02 and 3.94 ppm),choline-containing compounds(Cho)and myo-inositol(mI)were observed,and the ratios were analyzed by each other.Independent-samples t test was performed between two sets of data.Results In both visual cortex and optic radiation,the ratios of ml/Cr and mI/CrSee in DR group(0.664 ± 0.052 and 1.453±0.068 in visual cortex,0.717±0.074 and 1.484±0.114 in optic radiation)were significant higher than those in normal group(0.602±0.047 and 1.249±0.044 in visual cortex,0.679 ± 0.075 and 1.334±0.089 in optic radiation,P<0.05).In DR group,the ratios of CrSec/Cr,Cho/Cr and NAA/Cr in visual cortex and optic radiation were 0.458±0.043 and 0.488±0.052,0.481±0.057 and 0.807±0.110,1.633±0.105 and 1.709±0.140 respectively.In control group.the ratios of those were 0.484±0.041 and0.502±0.056,0.471±0.065 and 0.786±0.109,1.625±0.098 and 1.716±0.135 respectively.The ratios of CrSec/Cr,Cho/Cr and NAA/Cr had no statistic difference between two groups(P<0.05).Conclusion mI/CrSec is a typical change in the visual cortex and optic radiation region,1H-MRS as a noninvasive examination could provide biochemical and metabolic informations for diabetic patients.

Objective To determine the effect of combination of chest physiotherapy (CPT) and intermittent non-invasive ventilation for chronic obstructive pulmonary disease (COPD) patients with respiratory failure. Methods Ninety COPD patients with intermittent bi-level positive airway pressure (BiPAP) ventilation were randomly divided into 2 groups : control group (n=45) received BiPAP treatment after conventional anti-infection, phlegm treatment and support treatment; CPT group (n=45) received CPT before BiPAP treatment. Clinical symptoms, chest signs, chest X-ray, time of BiPAP therapy, PaO2, and PaCO2 after the treatment were evaluated. Results Compared with with the control group, patients in the CPT group significantly improved in clinical symptoms, chest signs, chest X-ray absorption as well as shorter BiPAP therapy time, PaO2 increase and PaCO2 decrease(P<0.05). Conclusion For COPD patients who need intermittent non-invasive BiPAP ventilation, receiving CPT can effectively improve the therapeutic effect. CPT and intermittent non in-vasive BiPAP ventilation cooperate in the treatment of COPD patients with respirstory failure.

Objective To evaluate the outcomes of open reduction and internal fixation of complex tibial plateau fractures with improved three combined approaches.Methods In the period from July 2014 to February 2016,7 complex tibial plateau fractures underwent surgical treatment.These patients included 5 male and 2 female,aged from 24 to 68 years old (average,39.7± 15.3 years).According to Schatzker classification,they were all of type V.And all of type 41B-3.1 by AO/OTA classification.All these fractures were exposed and reduction via three combined approaches.First let the patients lied in lateral prone position,expose the anterolateral and the posterolateral of the tibia1 plateau,and fix the fractures of the posterior in the posterolateral approach,then fix the fractures of the lateral in the anterolateral approach.Then turn the patients to supine position,fix the fractures of the medial in the anteromedial incision.All patients received regular reexamination.The knee function was evaluated at the final follow-up using The Hospital for Special Surgery (HSS) score,the activity of the knee was evaluated by Lysholm score,and the stability of the knee was checked by Lachmantest and Pivot-shift test.The tibial plateau angle,the posterior slope angle and Rasmussen X-ray score were assessed on the X-ray films.Results The average time of operation is (3.3±0.9) h,and the hemorrhage volume in operation was (341± 106) ml for the 7 patients.The wounds of 6 patients healed by (11.8± 1.3) days,while the wound of the rest one of them occurred fat liquefaction after operation who is very fat (BMI > 30) and suffered from diabetes.His wound healed by 21 days.These patients obtained follow-ups of 8 to 14 months (average,11.4±2.8 months).The average full weight-bearing time was 2-3 months (average,2.5±0.4 months).The fractures healed after 8 to 16 weeks (average,11.1 ±2.8 weeks).No displacement of the fractures or breakage of the implants occurred in our series.Nobody has activity limitation of the knee or pain because of the implant,and no never symptoms were noted postoperatively,so we would not take out the implant for these patients.The mean HSS score was 93.1±4.8 (range,from 85 to 100) at the final follow-up,and the excellent rate is 100%.The Lysholm score was 97.1±3.6 (range,from 90 to 100) at the final follow-up.The Lachman test and the Pivot-shift test were negative in our patients,and the mean knee flexion was 128.6±12.8°(range,from 105°to 140°).The fractures were all anatomical reduction by the X-ray after operation,and there had being no displacement of the fractures or breakage of the implants occurred during the follow-up period.The mean posterior slope angle was 8.29±2.87° (range,from 4 °to 12°),which was 8.71±2.63° (range,from 5 °to 14°) 6months after operation.The mean tibial plateau angle was 86.00± 1.41° (range,from 84 °to 88°),which was 86.43± 1.62° (range,from 84 °to 89°) 6 months after operation.The mean Rasmussen X-ray score was 16.86±1.57 (range,from 14 to 18),which was 16.57±1.51 (range,from 14 to 18) 6 months after operation,and the excellent rate are 100%.Conclusion For the complex tibial plateau fractures which simultaneous involved the medial,the lateral and the posterior,the improved three combined approaches showed the advantages of the convenient operation,the satisfactory results of reduction and fixation,and the less trauma and secondary damage,and could be worth for clinic.
