Spherical aberration is the major cause which affects the functional vision of the patients implanted with spherical intraocular lenses (IOLs). Aspheric IOLs are designed to eliminate the aberration like the nature lens, thus they can produce better visual quality. If it is feasible to customize IOL design to the individual cataract patient, aspheric IOLs may substitute the traditional spherical IOLs and become the trend of IOLs.

Congenital cataracts is the leading cause of visual disability in children worldwide.With the evolution of molecular biological technique,the researches of inherited congenital cataract mainly focus on localization and fuction characterization of the disease-associated gene,including crystallin,connexin,major intrinsic protein gene,etc.And great progress has been made for such genes in eye development,age-related cataract,epigenetics study.Thus,great attention must be paid to the functional research about congenital cataract candidate gene.

BACKGROUND:BACKGROUND:Present studies have shown that bone cement have less osteoinduction and slow degradation in the body,so the effect of alone application is not satisfactory. Therefore,people have modified them,hoping to research a new materials that can overcome all shortcomings above-mentioned. OBJECTIVE:To investigate the ability of decalcified bone matrix (DBM) and acrylic bone cement (ABC) compound in filling and repairing bone defect,and to determine the best component proportion of the composition. DESIGN,TIME AND SETTING:Randomized controlled animal experiments were performed at the Experimental Animal Center,Chongqing Medical University from May to September 2008. MATERIALS:ABC and DBM were prepared into compound material at various proportions (2:8,3:7,4:6,5:5,6:4). METHODS:The animal models of bilateral femur bone defects and fillers were established in the New Zealand White rabbits. The complex material was implanted on the bone defect; the ABC was used as blank control group. MAIN OUTCOME MEASURES:The complex and alone materials were examined by biomechanics and scan electron microscopes. Gross observation,histopathological and X-ray test were used at 4,8,12 weeks after operation respectively to observe the repaired and filled status of bone defect. RESULTS:DBM composite quality of the scope of 3:7 -6:4,the composite materials that existed in more cracks more than 100 ?m,when the DBM was less than 3:7,the material inside the aperture and the majority of material was similar to ABC,mass ratio greater than 6:4 when the DBM and the ABC could not effectively together solidification. When the mass ratio was increased,which matrix particles of demineralized bone and ABC,the compressive ultimate strength of composite materials was less than pure ABC (P

Objective To explore the clinical significance of APACHE Ⅱ score on risk stratification in patients with acute myocardial infarction.Methods One hundred and forty-two patients with acute myocardial infarction were included in the study who were admitted to hospital consecutively from Jan.2011 to Dec.2012.High risk group and low risk group were divided by the APACHE Ⅱ score.Some clinical variables at the first 24 h after admitted to hospital and occurring during the following 1 year were recorded Results The age in high risk group was 78.9 ±8.1,significantly higher than that in low risk group (65.8 ± 10.2;t =6.835,P ＜ 0.001).The cases with Killip Ⅲ and Ⅳ in high risk group were 10(29.4％) and 2(1.8％),lower than in low risk group (6 (1.8％) and 0 (0％) ; x2 =21.950,15.777 ; P ＜ 0.005).The level of creatine kinase-MB (CK-MB) and cardiac troponin Ⅰ in high risk group were (147.7 ±21.5) U/L and (105.5 ± 17.6) U/L,higher than in low risk group((105.5 ± 17.6) U/L,(42.9 ± 6.3) U/L; t =11.541,5.785 ; P ＜ 0.001).The incidence of severe cardiac events(malignant arrhythmia,heart failure,non fatal myocardial infarction and death from any cause in high risk group were 58.8％ (20/34),47.0％ (16/34),17.6％ (6/34) and 17.6％ (6/34),higher than in low risk group (29.6％ (32/108),3.7％ (4/108),6.4％ (7/108) and 6.4％ (7/108) ; x2 =8.274,36.665,3.876 and 3.876 ; P ＜ 0.05).Conclusion APACHE Ⅱ score is likely to be a simple and practical tool for risk stratification in patients with acute myocardial infarction.

Objective To evaluate the therapeutic effect and safety of forward-viewing,doublechannel endoscope in the process of ERCP in patients with bile duct diseases after Billroth-Ⅱ gastroenterostomy.Methods ERCP was applied to 46 patients with bile duct diseases using forward-viewing,doublechannel endoscope.All patients had the history of Billroth-Ⅱ gastroenterostomy.The success rate of selective cannulation,complication rate and the outcome of all the patients were recorded.Results The procedure succeeded in 38 patients with a success rate of 82.6％,and failed in 8.Of all the failing cases,the afferent loop couldn't be accessed in 6,failure in biliary cannulation in 2.Of 38 successful cases,bile duct stones were successfully removed in 31,metal stents placed for malignant bile duct obstruction in 4,and endoscopic balloon dilation for benign common bile duct stricture in 3.All patients recovered without complications of perforation,delayed bleeding or pancreatitis.Conclusion For patients with history of Billroth-Ⅱgastroenterostomy,ERCP with forward-viewing,double-channel endoscope yields to a higher success rate and lower complication rate.

Objective To investigate the application of admission test as a medical management in the labor room.Methods Eight hundred and fifty singleton pregnant women underwent admission test in labor room at Women's Hospital,School of Medicine,Zhejiang University from Dec.2009 to Dec.2011 were enrolled into this study.They were divided into two groups:normal group (admission test was normal,n =658) and abnormal group (admission test was abnormal or undetermined,n =192).Deliveries and perinatal outcomes of them were observed.The difference between the two groups were compared with two independent sample t test and Chi-square test.Results There were no significant differences in the mean age at delivery of the women and mean birth weight of neonates between the two groups (all P＞0.05).The cesarean section rate of normal group (34.2％,225/658) was lower than that (59.4％,114/192) of abnormal group (x2=3.93,P＜0.05).The rates of prematurc rupture of membranes (72.4％,139/ 192),fetaldistress (42.2％,81/192),neonatal asphyxia (16.5％,27/192) and neonatal complications (31.8％,61/192) in abnormal group were significantly higher than those [31.0％ (204/658),24.2％ (159/ 658),0.2％(1/658) and 2.6％ (17/658)] in normal group (x2 =105.78,40.84,52.54 and 151.92,P＜0.01respectively).Conclusions Admission test is a good method to forecast placental function during labor and perinatal outcomes,which might play an important role in medical management in labor room.

Objective To explore the correlation between coagulation and coagulation suppresion system disorders of portal vein thrombosis in patients of portal hypertension undergoing splenectomy.Methods Clinical data of 33 patients with postoperative portal vein thrombosis were enrolled.The clotting and coagulation inhibitor in portal vein blood and peripheral blood was detected and analyzed.Results The Hb,APTT,FIB,factor Ⅶ,protein C,AT-Ⅲ,CD62P of portal vein blood and peripheral blood before the surgery and on postoperative day 1,day 7,day 14 were no significant difference (P ＞ 0.05).The WBC,PLT,PT,D-Dimer of in portal vein blood before surgery were (2.9 ± 1.4) × 109/L,(37.5 ± 20.7) × 109/L,(16.1 ± 2.9) seconds,(0.7 ± 0.3) μg/ml,which were significantly different from those on postop day 1 (13.7 ±4.4) × 109/L,(86.3 ±34.6) × 109/L,(6.9 ±5.7) seconds,(16.1 ±2.9) μg/ml; day 7 (10.7 ±4.3) × 109/L,(312.4 ±137.2) × 109/L,(14.4 ±2.9) seconds,(7.6 ±4.4) μg/ml and day 14 (7.7 ± 3.3) × 109/L,(486.3 ± 216.7) × 109/L,(14.4 ± 2.9) seconds,(5.5 ± 4.4) μg/ml (P ＜ 0.05).WBC,PLT,PT,D-Dimer in preop peripheral blood were (2.4 ±0.8) × 109/L,(44.4 ± 25.8) × 109/L,(16.3 ± 3.0) seconds,(0.6 ± 0.4) μg/ml,which were significantly different from those on postop day 1 (13.7 ± 5.7) × 109/L,(75.1 ± 29.3) × 109/L,(13.7 ± 2.6) seconds,(6.8 ± 5.3) μg/ml; day 7 (10.6 ± 4.8) × 109/L,(337.9 ± 141.3) × 109/L,(14.0 ± 2.1) seconds,(7.6 ± 5.5) μg/ml and day 14 (7.8 ±3.9) × 109/L,(504.9 ±237.4) × 109/L,(14.0 ±2.1) seconds,(5.4 ±4.9) μg/ml postoperative (P ＜ 0.05).Conclusions The cause of postsplenectomy portal vein thrombosis is multifactorial.The dysfunction of coagulation-coagulation suppression system was just one of the conditions conducive to portal vein thrombosis after splenectomy.
