Objective:To explore whether metoprolol administration before emergency percutaneous coronary inter‐vention (PCI) can reduce incidence rate of reperfusion arrhythmia (RA) or not .Methods :According to random number table ,a total of 80 patients with acute anterior wall myocardial infarction (age< 75 years ,baseline heart rate >70 beats/min ,no PR interval prolongation ) were randomly and equally divided into routine treatment group (didn't receive metoprolol tartrate tablet before emergency PCI ) and metoprolol group (received metoprolol tartrate tablet 25 mg before emergency PCI ) .Incidence rate of RA after PCI was compared between two groups .Results:In metoprolol group ,a total of 32 cases received PCI and eight cases received percutaneous transluminal coronary angioplasty (PTCA);in routine treatment group ,a total of 35 case received PCI and five cases received PTCA ,suc‐cess rates of both groups were 100% .In metoprolol group , RA occurred in 4 cases ,including one case with ventric‐ular fibrillation (VF);in routine treatment group , RA occurred in 15 cases ,including four cases with VF .Inci‐dence rate of RA after emergency PCI in metoprolol group was significantly lower than that of routine treatment group (10.0% vs .37.5% ,P=0.032) .Conclusion:Metoprolol administration before emergency PCI can reduce in‐cidence rate of reperfusion arrhythmia in patients with acute myocardial infarction .

Newer retinal imaging technologies help us in understanding the pathogenesis of many retinal pathologies,such as diabetic retinopathy,age related macular degeneration,glaucoma and uveitis.Early detection of these retinal diseases can prevent the onset of progressive vision loss,and aid in the development of new treatment options.Retinal functional imager (RFI) is an unique and noninvasive functional imaging system.Unlike most of the available newer retinal imaging tools,the RFI not only shows retinal structural changes,but can directly monitor functional changes and measure hemodynamic parameters,such as retinal bloodflow velocity,oximetric state,etc.This article reviews the utility progress of RFI in various retinal diseases.

In recent years,there are many studies have reported that a small pupil syndrome appeared during routine phacoemulsification in patients with current or previous use of alpha-1 adrenergic receptor antagonists,with these clinical manifestations:an iris that appears floppy as it billows during normal irrigation and aspiration in the anterior chamber,a tendency for the iris to prolapse and progressive intraoperative miosis during surgery,which called intraoperative floppy iris syndrome This article mainly reviews the mobidity,pathogenesis,clinical features,complications,prophylaxis and treatment of the intraoperative floppy iris syndrome.

To construct recombinant reporter plasmids containing different Alpha gene segments and Alpha1-TFEB fusion gene and to evaluate the promoter activity of the Alpha gene. Methods:Promoter regions of the Alpha gene were predicted using a software Primer 0.5. Five Alpha gene segments with different lengths and a normal TFEB gene promoter (pTFEB) were amplified via polymerase chain reaction, and recombinant reporter plasmids containing different Alpha gene segments and a normal TFEB gene pro-moter were constructed. Liposome transfection was used to transfect these vectors into the human embryo kidney 293T cells. The pro-moter activity of the Alpha gene was evaluated via luciferase assay. Meanwhile, the recombinant Alpha1-TFEB plasmid was construct-ed and transfected into the 293T cells. The TFEB expression of the recombinant Alpha1-TFEB plasmid was then detected via Western blot. Results: Recombinant reporter plasmids containing different Alpha gene segments and pTFEB were constructed successfully. Compared with the luciferase activity of pGL3-Basic, that of the groups with Alpha1, Alpha2, Alpha3, Alpha4 and Alpha5 significantly increased (P<0.01). The luciferase activity also increased significantly in the groups with Alpha1, Alpha2 and Alpha5 compared with that of the pTFEB group (P<0.01). The TFEB expression of the pGL3-Enhancer-Alpha1-TFEB was significantly higher compared with that of the pGL3-Enhancer group. Conclusion:In t(6;11) translocation RCC, the Alpha gene has a strong promoter activity and it en-hances TFEB expression. The strongest promoter activity region is in Alpha5 with a sequence from 643 bp to 693 bp.

Objective To analyze the clinical profiles of lupus mesenteric vasculitis (LMV).Methods Thirty-six SLE patients diagnosed with LMV and 72 SLE patients (1:2) without LMV at West China Hospital between October 2009 and January 2012 were enrolled.The imaging,clinical manifestation,laboratory examinations data were analyzed retrospectively.Quantitative differences were analyzed by the Student's t and Z tests and qualitative data were compared with Chi-square.P value less than 0.05 was considered as statistically significant.Results ① The prevalence of LMV in patients with SLE was 1.2％(36/3 051),while 47％(17/36) as the initial symptom of SLE.Thirty-six LMV patients were all female.The prevalence of abdominal pain was 78％(28/36),nausea or vomitting was 58％(21/36),abdominal distension was 50％(18/36),diarrhea was 47.2％ (17/36),intestinal perforation was 3％ (1/36) and incomplete obstruction was 8％ (3/36).Enhanced CT scan showed 81％(25/31) patients suffered from intestinal dilation and (or) mesenteric edema;SLEDAI (17±5),C3 (0.44±0.25) g/L,C4 (0.10±0.09) g/L,Z value on above items were 4.30,-3.85 and-2.94 respectively compared to SLE patients without LMV,and all P＜0.05,the differemces were significant.In addition,Also,the proportion of ANA and anti-ENA antibody showed no significant difference.68.6％(13/36) patients were also diagnosed with lupus nephritis;61％(22/36) patients were treated with methylprednisolone more than 200 mg/d resulting in relief of symptom.Conclusion Female patients with SLE may be more likely to suffer from LMV;Enhanced abdominal CT scan is still essential to the diagnosis of LMV.LMV is correlated with urinary system malfunction.LMV always occurs in active lupus with low C3 and C4 level.More than half patients should be treated with corticosteroid and cyclophosphamide pulse therapy.

Infantile spasms constitutes an unique,age-specific epilepsy syndrome of early infancy characterized by epileptic spasms often accompanied by neurodevelopmental regression and an electroencephalograph finding of hypsarrhythmia.For the complex and various etiologies,the pathogenesis remains unclear.Although the relevant guidelines and consensuses are being updated all the time,but proven therapies are still limited because of efficacy,tolerability,at times even availability.In this paper,the current findings regarding up-to-date advances in the treatment of infant spasms were reviewed,especially in use of the corticosteroid and vigabatrin as well as the quality-of-care indicators for infantile spasms.
