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.

ObjectiveTo investigate the effect of nursing intervention on quality of life in patients undergoing total hysterectomy. Methods100 patients undergoing total hysterectomy were randomly divided into the intervention group and the control group with 50 patients in each group.The patients in the control group were given routine instruction after admission,before and after operation.The patients in the intervention group were given systematic nursing intervention on the basis of routine nursing.The quality of life three months postoperation was compared between two groups. ResultsThe quality of life in the intervention group three months after operation was better than that of the control group. ConclusionsSystematic nursing intervention for patients undergoing total hysterectomy during hospitalization can improve their postoperative quality of life.

The recent investigations have demonstrated that epigenetic such as DNA methylation and histone modification was closely associated with cell growth and malignant tumors, and epigenetic modification was responsible for an important cause of oncogenesis. However, for the recent years some observations have been also shown that the development of tumorigenesis was attributed to transformation expression in microRNA. The latest investigations have revealed that epigenetic was involved in modulation of microRNA expression, on the contrary some kinds of microRNAs could also control epigenetic, moreover, the reciprocal modulation between microRNA and epigenetic could regulate gene expression and induce tumorigenesis. At the same time the data likewise displayed that epigenetic adjusted microRNA expression principally in a way of DNA methylation or histone modification, nevertheless microRNA regulated epigenetic by way of methyltransferases expression, DNA methylation maintenance and histone modification. With regard to the reciprocal modulation between microRNA and epigenetic, a comprehensive and systemic review of reciprocal relationship in modulation of cell growth and oncogenesis was gived.

Objective To evaluate blood flow structure and quantify the variation of the flow within left ventricle,assess the impact of chronic heart failure(CHF) by vector flow mapping(VFM).Methods Twenty-seven patients with chronic heart failure and thirty controls were involved.The flow vector images on the section plane of the flow within the left ventricle were acquired by VFM.Time-flow(T-F) curve and all other peak systolic and diastolic flow curve include normal velocity profile,parallel velocity profile,vector profile,flow profile were analyzed by DSA-RS1 program.Results Ventricular ejection peak S,rapid ventricular filling peak E and atrial systole peak A were relatively lower at basal and middle segments in CHF group than normal control group.Normal velocity profile,velocity profile,flow profile at peak S and E were lower at basal and middle segments in CHF group than normal control group.Conclusions VFM technology could provide quantitative and intuitive information to demonstrate the flow structure of the ventricle and evaluate the cardiac function in patients with CHF.

Objective To detect the expression levels of vascular endothelial growth factor D ( VEGF-D) , D2-40 and MMP-7 in papillary thyroid carcinoma ( PTC) and to explore their relationship with micro lymphat-ic density, distribution,and cervical lymph node metastasis .Methods SP immunohistochemistry was used to study the expression of VEGF-D, D2-40 and MMP-7 in 38 cases of PTC with cervical lymph node metastasis , 45 cases of PTC without cervical lymph node metastasis , and 22 cases of normal thyroid tissues .Micro lymphatic density ( MLD) was counted .Results The expression level of VEGF-D in PTC with cervical lymph node metasta-sis and normal thyroid tissues had significant difference (χ2 =13.074, P=0.000, P<0.0167).The expression level of D2-40 in PTC with and without cervical lymph node metastasis had significant difference ( P<0.05 ) . MMP-7 expression in PTC with and without cervical lymph node metastasis had statistical significance ( 91.67%vs 73.33%, P<0.05).MLD in PTC with and without cervical lymph node metastasis and in normal thyroid tis-sues had statistical difference (11.7 ±3.5 vs 8.9 ±3.1 vs 3.9 ±2.7, P<0.05).Conclusion VEGF-D, D2-40 and MMP-7 are highly expressed in PTC and they are possibly related with cervical lymph node metastasis of PTC.

OBJECTIVE:To improve the information system of Out-patient pharmacy intravenous admixture center (OUIVA) to improve the pharmaceutical service rendered to the transfusion patient and ensure the safety of drug use. METHODS:The defi-ciency in OUIVA information system of our hospital were analyzed,in which improvement was made with respect to ungrouped doctor’s orders,inconsistency between the total doses charged and the prescribed doses and the error of transfusion days that occurred fre-quently. The conformity rate of out-patient fluid transfusion prescriptions and the time of patients’waiting for transfusion before and after the improvement were compared and evaluated. RESULTS:Improvement was made to OUIVA information system through the optimization of transfusion process,the application of condition limit,the adding of logical operation and verification and the other measures. After improvement,the unconformity rate of out-patient prescriptions in our hospital descended from 11.24% in 2013 to 3.69% in 2014,with an obvious increase in the accuracy rate of dispensing for fluid transfusion;and the time of patients’waiting for transfusion was shortened from 30-40 min to 15-20 min,with an increase in the degree of satisfaction of transfusion patients. CONCLUSIONS:The OUIVA information system can reduce the errors of drug dispensing for fluid transfusion and improve pharmaceutical services.
