Late in-the-bag dislocation of intraocular lens bag complex is a rare but potential complication after cataract surgery,which can affect the quality of patients'life seriously,and usually need surgical treatment.People are paying more attention to this complication,because it has been reported with increasing frequency in recent years.This complication may present after a long time frame.There is a research showing that the interval between cataract surgery and the dislocation was 10.9 years.The cumulative risk of IOL dislocation at 10 years,20 years,and 25 years after cataract extraction was 0.1％,0.7％,and 1.7％ respectively.Late in-the-bag IOL dislocation is a result of progressive zonular dehiscence up to many years after cataract surgery,and its genesis is multifactorial.This article reviews the incidence,possible mechanism and risk factors of late in-the-bag IOL dislocation.

Objective To study the effect of cold prolonged storage of rat livers with self-designed HYS solution on hepatic biochemical functions.Methods The preservation effect of HYD solution with that of UW solution and Lactate Ringer's solution(LR)was compared by using isolated perfused rat liver model.Results All the indices of hepatic biochemical functions in HYD group were better than in LR group for 12 h storage.The contents of ATP,TAN and AEC in HYD group were significantly higher than in Uw group for 36 h storage(P＜0.05).pH in HYD group was markedly higher than in UW group for 30 or 36 h storage(P＜0.05).The hydrolytic activities of H+-ATP ase in hepatic mitochondria and bile production were mildly higher in HYD group than in UW group(P＞0.05).No significant difference in AST,ALT and LDH in the effluent were found between HYD group and UW group(P＞0.05).Conclusions The effect of 12 h storage of rat livers with HYD solution might be better than with LR solution.The effect of HYD solution is similar to that of UW solution within 36 h storage.However.HYD solution is slightly superior to UW solution in some aspects.such aS improvement of energy metabolism during cold storage and reperfusion,prevention of intracellular acidosis.bile production and perfusion of liver in situ.

Objective To build a RNA interference vector for PQ-loop repeat protein (LRP) gene,and to evaluate the effect of the vector on the expression of PQ-LRP gene in Microsporum canis.Methods The PUC-PLULT and PCB309-PLULT vectors were constructed sequentially by using Agrobacterium tumefaciens-mediated T-DNA insertional mutagenesis,adding multiple cloning sites,and introducing the hygromycin-resistance gene.Microsporum canis was transformed with the PCB309-PLULT vector followed by a series of passages and hygromycin selection.Real-time quantitative PCR was performed to measure the expression of PQ-LRP gene in Microsporum canis before and after transformation.Results The intermediate vectors PUC-PLUT and PUC-PLULT were constructed and identified by PCR and gene sequencing.The 8 825-bp interference vector PCB309-PLULT was successfully built and confirmed by enzyme digestion.The optimum concentration of hygromycin for screening for Microsporum canis transformants was determined as 300 mg/L.The mRNA expression level of PQ-LRP was decreased by 61％ in the transformants as compared with untransformed Microsporum canis (0.39 vs.1.00).Conclusion The constructed PCB309-PLULT interference vector can effectively inhibit the expression of PQ-LRP gene in Microsporum canis.

ObjectiveTo observe the clinical effect of acupoint application on lipid metabolism in elderly diabetics with hyperlipidemia.Methods60 elder diabetics were divided into two groups.In the drugs group,patients were purely treated with simvastatin or lipanthyl.In the acupoint group, patients received acupoint application.The serum total cholesterol(TC), triglyceride (TG), low-density lipoprotein (LDL-C), high-density lipeprotein (HDL-C), aPoprotein A(ApoA) and apoprotein B(ApoB) ere measured respectively.Adverse events were observed.ResultsThe levels of TC、TG、LDL-C、ApoB were significantly dechned(all P ＜0.01 ～0.05).However,the rates of reduce lipid had no significant difference in two groups(P ＞0.05).The levels of HDL-C and ApoA were increased in the drugs group,but the homologous levels in the acupoint group showed no significantly change(all p ＞ 0.05).The adverse reaction in the acupoint group was significantly lower than that in the drugs group(P ＜0.05).ConclusionAcupoint application could decrease the blood lipid spectrum in the senile diabetics with hyperlipidemia.This therapeutics could reduce adverse drug reactions.

Objective To investigate the proper selection of methods of hepatic vascular control during(resection) of liver carcinoma.Methods Ninety-foury cases of liver carcinoma underwent hepatectomy using 4 different types of hapatic vascular control in our hospital.The operative time,amount of intraoperative blood loss,transfusion,and postoperative drainage,changes of postoperative liver function and complications were analyzed and compared between the 4 groups.Results Of the 94 cases,38(40.4%) underwent routine Pringle′s maneuver,34(36.2%) had selective hemihepatic vascular exclusion,18(19,1%) without(hepatic) inflow occlasion and 4(4.3%) had total vascular exclusion during hepatectomies.All tumors were entirely removed and operations were performed smoothly.Postoperative complications occurred 24 case-times and 2 patients(2.1%) died.Conclusions The selection of method of hepatic vascular control during(hepatectomy) for massive liver carcinoma should be comprehensively determined,based on the size and location of tumor,preoperative liver function,diffculty of hepatectomy and findings at intraoperative exploration.Proper method manner of hepatic vascular control is crucial for successful operation and uneventful recovery of the(patient).

Purpose 18F-FDG PET/CT,pathological and immunohistochemical analysis are adopted to explore the value of PET/CT in the early-stage calcification examination of atherosclerosis in rabbits and effects of Pioglitazone in treating early-stage calcification.Material and Methods Sixteen New Zealand male rabbits were randomly divided into two groups:Pioglitazone group and control group,witheight rabbits in each group.Atherosclerosis model was established.Rabbits in Pioglitazone group received gavage with Pioglitazone and were raised with high-fat diet for 20 weeks.Blood was drawn to exam high sensitivity C-reactive protein and matrix metalloproteinase-9.PET/CT was used to measure mean standardized uptake value (SUVmean) and maximum standardized uptake value (SUVmax).Rabbit aorta received immunohistochemical,the plaque area,density of macrophage,percentage of calcification area and apoptosis index between the two groups were determined and compared.Results On 20 week,high sensitivity C-reactive protein in Pioglitazone group (4.27±0.43 vs.6.51 ±0.91,P＜0.01),matrix metalloproteinase-9 (41.52± 1.99 vs.62.21 ±3.60,P＜0.05),SUVmean (0.55±0.18 vs.0.68±0.21,P＜0.01)and SUVmax (0.70±0.19 vs.0.82±0.30,P＜0.05) were obviously lower than those in control group.Plaque area,density of macrophage,percentage of calcification area and apoptosis index in control group were obviously higher than those in Pioglitazone group.Plaque area of related artery section was positively correlated with SUVmean (r=0.28,P＜0.01) and SUVmax (r=0.25,P＜0.05).Density of macrophage was positively correlated with SUVmean (r=0.50,P＜0.01) and SUVmax (r=0.46,P＜0.01).Percentage of calcification area was positively correlated with SUVmean (r=0.50,P＜0.01) and SUVmax (r=0.47,P＜0.01).Apoptosis index was positively correlated with SUVmean (r=0.61,P＜0.01)and SUVmax (r=0.60,P＜0.01).Conclusion Inflammation and macrophage apoptosis are of great importance in the early-stage of atherosclerosis.18F-FDG PET/CT imaging can be used to assess minor calcification.Pioglitazone can reduce inflammatory level of atherosclerosis of the experimented animals,inhibiting early-stage calcification.
