AIM: To observe acute coronary syndrome (ACS), including acute myocardial infarction (AMI), and unstable angina pectoris (UAP) and plasma monocyte chemoattractant protein-1 (MCP-1) in patients with restenosis after angioplasty, and compared with normal controls. METHODS: Sixty-eight patients were selected from the Department of Cardiology, Third Hospital Affiliated to Peking University between December 2005 and April 2006, including 30 patients with AMI, 20 patients with UAP and 16 patients with restenosis after angioplasty. Thirty healthy people were selected simultaneously to be the controls. All subjects knew and agreed with the items. The level of blood lipid was determined in all enrolled subjects: ① Blood sample was obtained from the elbow of patients with AMI immediately at hospitalization (2-12 hours from onset). ② Blood sample was obtained from patients of UAP group and patients of restenosis after angioplasty group immediately after the hospitalization (within 24 hours of onset). ③ Blood sample was obtained from fasting subjects of the normal control group in the morning. Blood sample was centrifuged, separated of the plasma and then frozen at -70 ℃. The level of plasma MCP-1 was determined with ELISA for statistical analysis. RESULTS: A total of 98 enrolled subjects were involved in the analysis of results, and no one withdrew from the study. Comparison in plasma MCP-1 among all groups: The plasma MCP-1 in ACS group, UAP group and restenosis after angioplasty group were (166.7?46.5,149.4?54.9,119.7?25.0,89.2?26.4) ng/L respectively, and it was significantly higher in ACS group, UAP group and restenosis after angioplasty group than that in the normal control group (F =21.27,P

In 2010,Ruijin Hospital Affiliated to Shanghai Jiaotong University School of Medicine and Chinese Center for Disease Control and Prevention conducted collaboratively a 2010 China Noncommunicable Disease Surveillance,and reported the results of diabetes prevalence and control in Chinese adults,which was published in the Journal of American Medical Association (JAMA) in 2013.This article is the interpretation of that report by original authors.

AIM:To observe and compare clinical effects of coaxial 1. 8mm microincision phacoemulsification and 3. 2mm small incision phacoemulsification.
●METHODS:A total of 117 eyes of 85 patients with age-related cataract in our hospital were divided randomly into two groups:43 patients (59 eyes) in the coaxial 1. 8 mm microincision cataract surgery group ( C - MlCS ) , 42 patients (58 eyes) in the coaxial 3. 2 mm traditional small incision cataract surgery group (C-SlCS). A total of 117 eyes were received phacoemulsification with intraocular lens implantation. Uncorrected visual acuity was recorded preoperatively and postoperatively at 1, 7, 30 and 90d. The effective phacoemulsification time and average ultrasound energy were recorded in surgery. Corneal endothelial cell and corneal topography were recorded preoperatively and postoperatively at 90 d.
●RESULTS:Uncorrected visual acuity ( logMAR) was no overall statistical significance difference between C-MlCS group and C-SlCS group (P>0. 05), but was significant statistical difference in different time-point within both groups(P<0. 05). Uncorrected visual acuity in different time-point had nothing to do with corneal wound size in cataract surgery(P>0. 05). On the 1 day after surgery, uncorrected visual acuity was 0. 16±0. 11 in C-MlCS group and 0. 22±0. 18 in C-SlCS group(P<0. 05). AVE was (7. 00± 2.72)% in C-MlCS group and (6. 16±3. 16)% in C-SlCS group (P>0. 05). EPT was (3. 09±1. 61)s in C-MlCS group and (3. 20±1. 92)s in C-SlCS group (P>0. 05). At 90 d after surgery, corneal endothelial cell loss percentage was (5. 81±2. 28)% in C-MlCS group and (5. 69±2. 38)% in C-SlCS group (P>0.05), SlA was (0.35±0.11) Din C-MlCS group and (0. 61±0. 13) D in C-SlCS group (P<0. 05).
● CONCLUSION: Compared with coaxial 3. 2mm traditional small incision cataract surgery, 1. 8mm coaxial microincision cataract surgery can get earlier visual rehabilitation and significantly reduce SlA. The coaxial 1. 8mm microincision cataract surgery is safe, effective and deserves further clinical applications.

Background Vitronectin is a glycoprotein that has a variety of functions.Its expression was markedly higher in the retina of oxygen induced mice,which was confirmed in our animal model,and also increased in human umbilical vein endothelial cells (人 UVECs) that were cultured in high glucose.However,there was no evidence that showed vitronectin was involved in retinal neovascularization.Objective This study was to observe the influence of vitronectin on cytoskeleton remodeling,cell migration and blood vessel formation in 人 UVECs conditioned by high glucose.Methods 人 UVECs were cultured in high glucose and the expression of vitronectin was knocked down using RNA interference technology.The experiments were divided into the high glucose group (人 UVECs were conditioned with DMEM medium that contained 50 mmol/L glucose),negative interference group (人 UVECs were transfected with control siRNA in advance,and then were conditioned with DMEM medium that contained 50 mmol/L glucose) and positive interference group (HUVEC were transfected with vitronectin siRNA in advance,and then were conditioned with DMEM medium that contained 50 mmol/L glucose).The protein expression of vitronectin was measured by Western blot,and the microfilament cytoskeleton of 人 UVECs was examined by immunofluorescence cytochemical staining followed by fluorescence microscopy.Cell migration ability in a scratch wound assay and blood vessel formation ability in a matrigel assay of 人 UVECs were evaluated.The general differences were analysed by One-Way ANOVA ;further contrasts of the two groups were analysed by the LSD-t test.Results The differences in vitronectin expression of the three groups were not obvious at 0 hour (F=1.064,P＞0.05).After 24 hours,vitronectin expression was highest in the high glucose group,lower in the negative interference group,and the lowest in the positive interference group,and the differences were significant (F =15.519,P＜0.05).After 48 hours,vitronectin expression of the three groups displayed the same pattern,and the differences were also significant (F=37.521,P＜0.05).Immunofluorescence showed that the cytoskeleton structure was most obvious in the high glucose group,moderate in the negative interference group,and was the least obvious in the positive interference group,after both 24 hours and 48 hours.In the scratch wound assay,the cell migration ability of the high glucose group was the highest,lower in the negative interference group,and the lowest in the positive interference group after 24 hours,and the differences were significant (F=90.685,P＜0.05).After 48 hours,the cell migration abilities of the three groups displayed the same pattern,and the differences were also significant (F=67.880,P＜0.05).In the matrigel assay,after 6 hours,the number of blood vessels formed in the high glucose group was more than that in the negative interference group,and the least amount was found in the positive interference group.The differences among of them were significant (F =86.653,P＜0.05).The number of blood vessel formed in the positive interference group was also the lowest after 12 hours,and the differences were also significant (F=18.992,P＜0.05).Conclusions Vitronectin can bring about cytoskeleton remodeling,increase in cell migration,and enhancement of blood vessel formation in 人 UVECs conditioned in high glucose.It may be one of the important influence factors of diabetic retinopathy.
