Objective To compare the optical properties and visual quality between Tecnis ZMB00 and AcrySof ReSTOR SN6AD1 multifocal intraocular lens (MIOL) in patients undergoing cataract surgery.Methods A total of 120 patients (130 eyes) who umderwent elective cataract surgery in our hospital from March 2012 to July 2015 were selected prospectively.All patients were treated with diffractive MIOL,and divided into group A (Tecnis ZMB00 group) and group B (AcrySof ReSTOR SN6AD1 group).The uncorrected distance visual acuity (UCDVA),uncorrected near visual acuity (UCNVA),uncorrected medium distance visual acuity (UCIVA),best corrected distance visual acuity (BCDVA) and best corrected near visual acuity (BCNVA) were measured before and after surgery.The defocusing curve was drawn for analysis of the contrast sensitivity,and the postoperative visual function and survival quality questionnaire (VF-14) was used to evaluate the postoperative visual quality.Results At 1 week,1 month and 3 months after surgery,recovery of UCNVA,UCIVA and BCNVA in group A was better than that in group B (all P < 0.05).At 1 week and 3 months after surgery,the recovery of UCDVA in group A was better than that in group B (all P < 0.05).At 3 months after surgery,the spherical equivalent was lower in group A than group B (P < 0.05).The contrast sensitivities under scotopia,photopic glare and scotopic glare of different frequencies in group A were higher than those in group B (all P<0.05).The VF-14 score in group A at 3 months after surgery was lower than that in group B (P<0.05).In group A,0.0 D and-2.5 D formed 2 peaks,and from-2.0 D to-2.5 D formed the platform stage,while in group B,only 0.0 D and-3.0 D formed 2 peaks.Conclusion The implantation of Tecnis ZMB00 MIOL after cataract surgery can improve the uncorrected visual acuity of treated eye,contrast sensitivities,postoperative visual function and quality of life of patients.

OBJECTIVE:To obverse the efficacy and safety of tolynicate and napthylacetic acid and atorvastation combined with Danshen injection in the treatment of alcoholic hyperlipemia syndrome. METHODS:21 patients with alcoholic hyperlipemia syndrome were enrolled. All patients were given maintaining acid-base balance,oxygen inhalation and other conventional treatment. Based on it,they were orally given 75 mg Tolynicate and napthylacetic acid tablet,3 times a day+20 mg Atorvastatin calcium tab-let,once a day+4 ml Compound danshen injection,adding into 150 ml 5% Glucose injection by intravenous infusion,once a day. The treatment course for both groups was 30 d. Clinical efficacy,ALT,AST,TBIL,TC,TG,RBC and Hb before and after 6, 12,18,24 and 30 d,and incidence of adverse reactions were observed. RESULTS:After treatment,the total effective rate was 95.3%and incidence of adverse reactions was 28.5%. The ALT,AST and TBIL after 6,12,18,24 and 30 h and TC and TG after 18,24 and 30 h were significantly lower than before and gradually decreased by time;RBC and Hb after 12,18,24 and 30 h were significantly higher than before and gradually increased by time,the differences were statistically significant(P<0.05). CON-CLUSIONS:tolynicate and napthylacetic acid and atorvastation combined with Danshen injection is effective in the treatment of al-coholic hyperlipemia syndrome,with good safety.

Objective To explore the effects of computerized working memory training on working memory and brain functional activition for stroke paitents. Methods 3 stroke patients voluntarily joined in the study, 10 healthy adults were recruited as control group. The patients received computerized working memory training for 4 weeks. Cognitive psychological tests (the n-back task, Stroop task and Raven`s Advanced Progressive Matrices task) and neuroimaging test (task- state functional magnetic resonance imaging) were administered before and after treatment. Results Working memory training significantly improved the working memory, fluid intelligence and attention for each trained patient (P<0.001), and could renovate the abnormal functional activity model and reorganize the functional brain network. Conclusion Computerized working memory could be used as an effective cognitive rehabilitation intervention for stroke patients.

Objective To screen for serum protein differentially expressed between women whose fetuses had congenital heart defects(CHD) and women who had normal fetuses. Methods Serum samples were collected from pregnant women whose fetuses had CHD and those whose fe?tuses had no CHD,including a CHD group of 40 women and a control group of 10 women. The CHD group included 4 subgroups as follows:tetralo?gy of Fallot,ventricular septal defects,persistent truncus arteriosus,and a mixture of relatively rare types of CHD(n=10 each). Samples in the same group were pooled to obtain equal amounts of proteins ,and the iTRAQ proteomic approach was used to identify and quantify the proteins dif?ferentially expressed among these groups. Results We successfully identified 606 proteins,among which 47 showed at least a 1.5?fold difference between the CHD and control groups. Among the 47 proteins,23 and 24 were upregulated and downregulated,respectively. Conclusion Several proteins associated with CHD could be identified by using the iTRAQ proteomic approach ,and various proteins were involved in the pathogenesis of CHD in this study.

Objective To evaluate the value of MRI in acute ankle distortion without evidence of fracture. Methods The MRI appear-ances of 21 cases with acute trauma in the ankles were retrospectively analyzed,focusing on the presence or absence injuries of lateral collat-eral ligamentous complex,bone and osteochondral lesions,MRI was performed within 48 h of trauma. Results Bone bruise was observed in 15 patients. There were injuries of the lateral ligaments in 4 cases and the medial ligaments in 1 case. Injury of the osteochondral lesion was in 5 cases and Achilles tear was in 3 cases. Conclusion MRI have diagnostic value for acute ankle injury.

Objective To analyze the transcription level of new tumor suppressor gene SLC5A8 mRNA in colorectal cancer tissues.Methods Collected specimens of 23 cases with colorectal cancer and cut out carcinoma tissues and Pericarcinomatous tissue respectively,then used real time fluorescent quantitative PCR (RT-qPCR)to detect the transcription level of gene SLC5A8 mRNA,and the results of carcinoma tissues and pericarcinomatous tissues were analyzed by t test.Results The transcription level of new tumor suppressor gene SLC5A8 mRNA in colorectal cancer tissues is significantly lower than pericarcinomatous tissue (P =0.002).Conclusion The expression of gene SLC5A8 in colorectal cancer tissues is declining or missing,suggesting it has a certain relationship with the incidence of colorectal cancer.

Objective To detect the sequence of SLC29A1 gene rs1288 single nucleotide polymorphism (SNP) in advanced pancreatic cancer patients,and to explore its correlation with gemcitabine toxicity and prognosis.Methods Peripheral blood samples were collected and DNA was extracted.The segment containing SLC29A1 gene SNP (rs1288) was amplified by PCR,and then DNA sequencing was conducted to identify SLC29A1 gene SNP (rs1288).According to the sequencing results,the patients were divided into SLC29A1 gene rs1288 T→A mutation type group and wild type group.Clinical data,toxicity of gemcitabine chemotherapy,progression free survival (PFS) and overall survival (OS) between two groups were compared.Results A total of 83 pancreatic cancer patients were enrolled.Sequencing results showed that SLC29 A1 gene 1288 T→A mutation type was present in 52 patients and wide type was observed in 31 patients,so mutation rate was 62.7%.All the patients in both two groups could tolerate the gemcitabine toxicity,and no chemotherapy related death occurred.There were no statistical differences on the gender,age,CA19-9,tumor site,size and TNM stage between the two groups.There were statistically higher iucidences of leukopenia and thrombocytopenia in the SLC29A1 gene rs1288 T →A mutation type group compared to the wild type group (55.8% vs 32.3%,P<0.05;40.4% vs 19.4%,both P<0.05).Median OS and PFS in mutation type group were shorter than those in wide type group (11 months vs 14 months,P < 0.05;9 months vs 12 months,P < 0.05).Conclusions Advanced pancreatic cancer patients with the SLC29A1 gene rs1288 T→A mutation type had a higher incidence of adverse reaction in gemcitabine chemotherapy and a worse therapeutic effect,and thus detecting the mutation of SLC29A1 gene rs1288 point mutation may serve as a marker for evaluating the toxicity and prognosis of gemcitabine chemotherapy in patients with pancreatic cancer.
