Abstract?AIM: To analyze the effects of femtosecond laser assisted cataract surgery ( FLACS ) in the treatment of cataract and its effect on prognosis.?METHODS:Forty-two cases (42 eyes) of patients with cataract who were treated in the Department of Ophthalmology in our hospital between January 2012 and December 2014 were selected as the study objects. According to the order of treatment, they were divided into control group and observation group, 21 cases in each. The control group was treated with traditional phacoemulsification cataract surgery ( PCS ) . On the basis, the observation group was treated with femtosecond laser. The effective phacoemulsification time (EPT), cumulative dissipated energy (CDE), fluid flow and monitored pressure of the two groups were recorded.The rate of corneal endothelial loss and the situation of Tyndall phenomenon were statistically analyzed.The two groups were followed up for 1a.The long-term visual acuity recovery was observed.The best corrected visual acuity ( BCVA ) was recorded, and the long-term complications were statistically analyzed.?RESULTS: 1 ) The total response rate in observation group was 95% while in control group was 90% ( P>0.05);2) the surgery time of the observation group was longer than that of the control group ( P<0.05) but EPT was shorter than that of the control group.CDM and liquid flow were less than those of the control group ( P<0.05 ); 3 ) at 1d after surgery, there was no significant difference in intraocular pressure between the two groups (P>0.05); the rates of Tyndall phenomenon and corneal endothelial loss in the observation group were lower than those in the control group ( P<0.05);4) BCVA of the two groups at different time after surgery were significantly higher than that before surgery (P<0.05). However, at 1d, 3mo, 6mo and 1a after surgery, BCVA of the observation group was better than that of the control group ( P <0.05 ); 5 ) the incidence of complications in the observation group after surgery (14%) was lower than that in the control group (43%) (P<0.05).?CONCLUSION: The surgical effects of FLACS in the treatment of cataract are good.After surgery, the visual acuity of patients is improved significantly and the incidence of postoperative complications is low. However, the surgery time is long and cost is high, so it is difficult to popularize.

Objective To investigate the transactivating effect of hepatitis C virus(HCV)core protein on inducible nitric oxide synthase(iNOS)gene promoter and the molecular biological mecha- nisms of HCV pathogenesis.Methods Polymerase chain reaction(PCR)technique was employed to amplify the sequence of iNOS promoter by using HepG2 genomic DNA as template,and the product was cloned into pGEM-T vector.The iNOSp gene was cut from T-iNOSp by KpnⅠand XhoⅠ,and then was cloned into pCAT3-Basic,the constructed vector was named as pCAT3-iNOSp,pCAT3-iN- OSp was transfected into the LO_2 cell line.LO_2 cell was also cotransfected with pcDNA3.1(-)-core and pCAT3-iNOSp by FuGENE 6 transfection reagents.The LO_2 cells transfected with pCAT3-Basic was used as negative control.The activity of CAT in LO_2 cells was detected by an ELISA kit after 48 hours,which reflected the transactivating function of HCV core protein to iNOS gene promoter.Re- sults The expressive vector pcDNA3.1(-)-core and report vector pCAT3-iNOSp had been construc- ted and confirmed by restriction enzyme digestion and sequencing.The expression of CAT in LO_2 cells transfected with pCAT3-iNOSp and peDNA3,1(-)-core was 11 times as higher as that of pCAT3-bas- ic,and 6 times as higher as that of pCAT3-iNOSp.Conclusion It is suggested that HCV core protein can transactivate iNOS gene promoter.

Objective To investigate the influencing factors for prehospital delay in patients with acute myocardial infarction (AMI).Methods A total of 807 consecutive patients with AMI who presented to the emergency department of Beijing Anzhen Hospital were analyzed. The influence of several potential risk factors on the prehospital delay time (PDT) was evaluated by comparing patients admitted more than 2 hours after onset of chese pain with those admitted within 2 hours after onset. Results Among 807 patients, 402 came to the hospital within 2 hours while the others arrived at the hospital after 2 hours. The median PDT was 130 min. Among the potential variables, advanced age, history of diabetes mellitus, occurrence of symptom at night and use of emergency medical service significantly affected PDT by multivariate analysis. Conclusion Interventions aimed at reducing the prehospital delay in AMI should primarily focus on the awareness of the risk and help-seeking behavior of patients.

BACKGROUND:At present, there stil remain controversies concerning the choice of tibial slope in unicompartmental knee arthroplasty, and the related biomechanical studies are rare. OBJECTIVE:To find the rational tibial slope in mobile-bearing unicompartmental knee arthroplasty through the results of finite element analysis. METHODS:A finite element model of normal knee was established and validated using the techniques of three-dimensional reconstruction and finite element pre-processing. Then the finite element models of unicompartmental knee arthroplasty with different tibial slopes were established based on the normal knee model. The finite element analyses were conducted after the boundary conditions and loads were unified. RESULTS AND CONCLUSION: The finite element models of unicompartmental knee arthroplasty with different tibial slopes were established successfuly. The results of the finite element analyses indicated that the posteromedial tibial cortical and cancelous bone stress increased gradualy as the posterior slope increasing, as wel as the load distribution and the cartilage contact pressures of lateral compartment. The anteromedial tibial cortical stress increased significantly with the anterior slope. A posterior tibial slope of 0°-7° can be recommended when implanting a mobile-bearing unicompartmental knee arthroplasty.
