Objective To evaluate the visual outcomes,depth of focus and safety after implantation of the Acrysof ReSTOR and the Acrysof Natural.Design Nonrandomized clinical trial.Participant 53 patients with age-related cataract(61 eyes)were divided into two groups:Acrysof ReSTOR group(MIOL)included 28 patients(31 eyes),and reference group-Acrysof Natural group(SIOL)included 25 patients(30 eyes).Method All patients underwent phacoemulsification and IOL implantation.At 1 week,1 month and 3 months postoperatively,distant and near visual acuities were observed,and depth of focus was measured 3 months postoperatively.Main Outcome Measure Uncorrected distant visual acuity(UCDVA),uncorrected near visual acuity(UCNVA),best corrected distant visual acuity(BCDVA),best corrected near visual acuity(BCNVA),distant corrected near visual acuity(DCNVA),depth of focus.Result At 3 months postoperatively,in MIOL group:UCDVA was 0.90?0.15,UCNVA was 0.70?0.19,DCNVA was 0.73?0.21 and depth of focus was 5.5D(+1.5～-4.0D),while in SIOL group:UCDVA was 0.84?0.14,UCNVA was 0.36?0.10,DCNVA was 0.26?0.08 and depth of focus was 2.5D(+1.0～-1.5D).In MIOL group,UCDVA and UCNVA at 1 month were markedly better than those at 1 week. Conclusion Acrysof ReSTOR can provide excellent outcomes both in distants and near visions and it may reduce the dependence on spectacles in near vision.(Ophthalmol CHN,2006,15:344-347)

Objective To explore the effect of kangfuxin liquid topical treatment on open wound of postoperative perianal abscess.Methods200 cases of patients with open wound abscess surgery in our hospital from February 2014 to September 2016 were randomly divided into control group and experimental group,with 100 cases in each group.The control group was given conventional treatment, the experimental group were treated by kangfuxin liquid.The relevant therapeutic indicators and clinical healing time between two groups were compared.ResultsThe effective rate of the treatment group was 93.0%, which was significantly higher than that of the control group (85.0%), the difference was statistically significant(P<0.05).The granulation growth period of the experimental group was (5.14±1.41) days, and the average healing time was (15.21±2.49) days.Which were significantly shorter than those of the control group[(7.45±1.32) days, (21.16±2.69) days], and the differences were Statistical differences (P<0.05).ConclusionTo improve the treatment effect to a great extent open wound infection of kangfuxin liquid in treatment of perianal abscess after surgery, shorten the healing time, improve the patient's symptoms, with further clinical promotion and application significance.

?AIM: To evaluate the effects on recovering of corneal wound and postoperative discomfort of different methods for primary pterygium.?METHODS: Forty-seven cases ( 60 eyes ) of primary pterygium were excised under microscope with limbal epithelial transplantation, with sharp dissection ( 24 cases, 30 eyes, Group A) and blunt dissection (23 cases, 30 eyes, Group B).All cases were followed up for 1d to 1mo.?RESULTS: The recovering of corneal wound was better in Group B on 1st day and 3rd day after surgery.Pain, photophobia and tears, foreign body sensation were more serious in group A on 1st day after surgery with a statistically significant difference (P=0.005,0.015,0.012). Pain, photophobia and tears, foreign body sensation were more serious in Group A on 3rd day after surgery with a statistically significant difference ( P=0.019,0.018, 0.015).There was no statistically significant difference on 1wk and 1mo after surgery (P>0.05).? CONCLUSION: Compared with sharp dissection, primary pterygium excised with blunt dissection can significantly improve recovering of corneal wound and postoperative discomfort.

OBJECTIVETo observe the effect of Zhenqing Recipe (ZQR) on non-alcoholic fatty liver (NAFL), and the expression of hepatic salt-inducible kinase 1 (SIK1) and sterol-regulatory element binding protein-ic (SREBP-lc) in type 2 diabetes rats.

METHODSA rat model of type 2 diabetes was established by high fat/sucrose diet combined with intraperitoneal injection of small dose streptozotocin (STZ) . Modeled rats were randomly divided into the model group, the ZQR group, and the metformin group, 8 in each group. Eight rats were recruited as a normal control group. ZQR at the daily dose of 12 g crude drugs/kg was administered to rats in the ZQR group by gastrogavage. Metformin suspension at the daily dose of 150 mg/kg was administered to rats in the metformin group by gastrogavage. Equal volume of distilled water was administered to rats in the normal control group and the model group. All medication lasted for 12 weeks. The levels of fasting blood glucose (FBG), free fatty acid (FFA), serum triglyceride (TG), serum total cholesterol (TC), serum alanine aminotransferase (ALT), and aspartate aminotransferase (AST) were detected. The body weight and wet liver weight were weighed, and the liver weight index calculated. The liver TG content was measured. The pathological changes of liver and the expression of SIK1 were observed by HE staining and immunohistochemistry. The mRNA and protein expression of SIK1 and SREBP-1c were detected using RT-PCR and Western blot.

RESULTSCompared with the normal control group, FBG, FFA, TG, TC, ALT, AST, liver weight index, and liver TG contents significantly increased (P < 0.01); liver steatosis was severe, the mRNA and protein expression of SIK1 obviously decreased (P < 0.01); mRNA and protein expression of SREBP-1c increased (P < 0.01). After drug therapy, compared with the model group, FBG, FFA, TG, TC, ALT, AST, and liver weight index significantly decreased, liver TG contents significantly decreased, the mRNA and protein expression of SIK1 obviously increased, while mRNA and protein expression of SREBP-1c obviously decreased (P < 0.05, P < 0.01) in the ZQR group and the metformin group (P < 0.05, P < 0.01); and the pathological changes were also improved. All the indices were improved more in the ZQR group (all P < 0.05).

CONCLUSIONIn this experiment, we found that the expression of SIK1 decreased in NAFL rats with type 2 diabetes. ZQR could alleviate lesion of NAFL type 2 diabetes rats possibly by up-regulating hepatic SIK1 expression at mRNA and protein levels.

The present paper proposed a central-driven structure of upper limb rehabilitation robot in order to reduce the volume of the robotic arm in the structure, and also to reduce the influence of motor noise, radiation and other adverse factors on upper limb dysfunction patient. The forward and inverse kinematics equations have been obtained with using the Denavit-Hartenberg (D-H) parameter method. The motion simulation has been done to obtain the angle-time curve of each joint and the position-time curve of handle under setting rehabilitation path by using Solid Works software. Experimental results showed that the rationality with the central-driven structure design had been verified by the fact that the handle could move under setting rehabilitation path. The effectiveness of kinematics equations had been proved, and the error was less than 3° by comparing the angle-time curves obtained from calculation with those from motion simulation.

AIM:To discuss the technique for preparing high-purity solanesol from tobacco. METHODS:The pre-treated tobacco leaves were extracted with mixed solvent of petroleum ether and ethanol,and saponified to obtain solanesol extract; The solanesol extract got through redissolution and dewaxing,then crystallized in the temperatare of -18 ℃; Finally purified by macroporous resin(YPR-Ⅱ,D-1300,HZ-816,HZ-802). RESULTS:The ratio of mixed solvent of petroleum ether and ethanol was 1 ∶ 4,ratio of liquid to materials was 1 ∶ 12,solanesol purity was about 32% after saponification,then crystallization made the purity up to 63. 4% ,finally purified through macroporous resin,the solanesol purity reached above 93. 6%. CONCLUSION:Through the general solvent extraction,saponification,crystallization and macroporous resin adsorption process,the solanesol purity of the product reaches higher than commonly expected values.
