Objective To study the clinical effect of small incision cataract extraction in the treatment of acute angle-closure glaucoma with cataract.Methods Fifty-eight patients with acute angle-closure glaucoma combined with cataract were selected,and according to the digital table they were randomly divided into two groups:control group and observation group.The patients in the control group were treated by conventional method.The patients in the observation group were treated with small incision cataract.The changes of intraocular pressure,anterior chamber depth and visual acuity before and after treatment were observed.The incidence of complications and the satisfaction of treatment were compared between the two groups.Results There were no significant differences in IOP,visual acuity and anterior chamber depth between the two groups before treatment(all P>0.05).After treatment,the intraocular pressure,anterior chamber depth and visual acuity of the observation group were (10.2±4.0)mmHg,(3.3±0.5)mm,(0.85±0.08),respectively,which of the control group were (17.5±5.0)mmHg,(3.2±0.5)mm and (0.50±0.06),respectively.The improvement of intraocular pressure and anterior chamber depth of the observation group was more significant than the control group(t=0.120,0.520,1.012,all P<0.05).The satisfaction rate of the observation group(96.6%) was higher than that of the control group(75.8%)(χ2=9.823,P<0.05).There was no significant difference in the incidence of complications between the two groups(P>0.05).Conclusion Small incision cataract extraction is an effective treatment for acute angle-closure glaucoma complicated with cataract,and the postoperative complications are less.The patients are satisfied with the treatment and deserve to be popularized.

ObjectiveTo prospectively investigate whether any of the perfusion parameters would predict early tumor response to chemotherapy and/or radiotherapy and prognosis in non-small cell lung cancer (NSCLC). MethodsIn a prospective series, Perfusion CT were performed in 152 patients suspected lung cancer with 16-slice or 8-slice multislice CT. Contrast medium (50 ml) was injected at a rate of 4 ml/s with a power injector.The scanning delay was 10 seconds and the scanning time was 50 seconds.Among 152 patients,123 patients were proved lung cancer by pathology.With the perfusion 3.0 software, the parameters including blood flow (BF), blood volume (BV), mean transit time (MTT) and capillary permeability surface area product (PS) were calculated. The perfusion image quality was evaluated on a 4-1eveal scale. The treatment response after chemotherapy and(or) radiotherapy was assessed with Response Evaluation Criteria in Solid Tumors (RECIST) ,and then the relationship between perfusion parameters with early tumor response to chemotherapy and(or) radiotherapy was evaluated. Student t test and Kaplan-Meier estimates were used for data analysis. ResultsIn 84 patients (68.3%), the perfusion image quality was staged level 2 (moderate) and level 3 (good). Among them, 35 patients with NSCLC were assessed with RECIST after chemotherapy and (or) radiotherapy.In these 35 patients, The BF of responders and nonresponders was (81.0±33.6)and (56.3±23.1) ml·min~(-1)·100 g~(-1),respectively, which was significantly different(t=2.393, P=0.023). The median PFS of low-BF group (BF≤80 ml·min~(-1)· 100 g~(-1)) and high-BF group (BF>80 ml·min~(-1)·100 g~(-1)) was 11.8 and 8.0 months respectively (P>0.05), and the median PFS of low-BV group (BF≤6 ml/100 g~(-1)) and high-BV group (BF>6 ml/100 g~(-1)) was 9.2 and 8.0 months respectively(P>0.05), both of them were not significantly different.ConclusionNSCLC in high perfusion are relatively sensitive to chemotherapy and/or radiotherapy, and the response rate is relatively higher, but the progress time is relatively shorter.
