The aim of synthetic biology is to design artificial life systems. Such system is hoped to create a better production process with desired ability for bioproduction, biotransformation, adaption and environmental monitoring. However, to design a life system involves understanding the cellular regulation networks at multiple levels, in which the controls of protein level, subcelluar location, and activity are especially critical. Thus tuning protein expression has become essential tools in synthetic biology studies, such as part design, module assembly and compatibility optimization. Protein budget, just like budget for a factory, can be thought as the cost estimating criteria for an artificial cell factory. Protein budget control has provided a powerful optimization strategy for synthetic biology.

Objective To study the residual gallbladder stones and the relationship between the onset of acute pancreatitis and its surgical treatment.Methods Retrospective analysis was made in 13 patients with residual gallbladder admitted tO the hospital from June 1998 to December 2007,of which 8 cases of residual gallbladder stones and acute pancreatitis were invostigated.Thirteen cases of patients had underovent cholecystectomy 2 to 9 years before,the first symptoms occurred before 1 month to 8 years.Other remnants of the gallbladder were diagnosed by B-ultrasound and CT,magnetic resonance cholangiopancreatography (MRCP).Results Two cases were confirmedas pigment stones;6 cases as cholesterol stones(size0.2 cm ～0.5 cm,an average of 3.2 cm);1 cases as anonlalous pancre-aticobiliary junction(anomalous pancreaticobiliary ductal union,APBDU);5 cases as anomal;8 cases(61.5%)as episode of acute pancreatitis.Au patients underwent resection of residual gallbladder,with line choledochal cyst excision and biliary-enteric Roux-en-Y internal drainage in 1 case.choledocholithotomy T-tube drainage in 3 cases.Postoperative follow-up of residual gallstone was done in 8 cases,no pancreatitis attack in 6 cases,pancreatitis attack in 2 cases.Significant difference was found in onset of acute pancreatitis (P=0.019,P<0.05).Five patients without stones in patients with postoperative all none pancreatitis attack.Conclusion Patients with residual gallbladder stones are prone to acute pancreatitis,and cholecystectomy for patients with residual treatment Can reduce the pancreatitis attack.

Ocular surface diseases are common diseases in ophthalmology.It is difficult for clinicians to make early and accurate diagnosis based on symptoms, signs and serologic examination.Compared with the blood test, the tear test can reflect the condition of the local ocular surface and it has the characteristics of being non-invasive, having high diagnostic accuracy and fast diagnostic speed.Tear detection uses modern detection techniques such as polymerase chain reaction, enzyme-linked immunosorbent assay, gene chip and protein chip to detect the pathogen and immune components in tear, including microbial nucleic acid, tear antibody (IgM, IgG, IgE, IgA, antinuclear antibody, etc.) and cytokines (interleukin, tumor necrosis factor, interference factor, transforming growth factor, epidermal growth factor, etc.). Tear detection provides information about the pathogen infection and immune response on the ocular surface.At present, a large number of domestic and foreign tear detection studies show that there are certain regular changes in tear composition, not only in ocular surface diseases, uveitis, fundus diseases, thyroid related ophthalmopathy, but even in systemic diseases such as diabetes, hepatitis B, acquired immune deficiency syndrome etc.In addition, the research of tear pathogen and immune components is of great significance to study the cause, biochemical and immune process, treatment of diseases.In this paper, the latest research progress of tear collection, the clinical significance of tear pathogen and immune components and the characteristics of tear in various diseases was summarized and analyzed to provide reference for clinical practice.

As an advanced quantitative technology for cells, flow cytometry, which can make multi-paramter quantitative analysis and sorting of individual cells or biological particles, has been widely used in immunology, oncology, hematology and other fields of medical research and clinical diagnosis in recent years.It can quantitatively detect the expression levels of cytokines and the distribution characteristics of cell subsets in the intraocular fluid.Compared with traditional enzyme-linked immunosorbent assay, cell morphology and immunohistochemistry, it has the advantages of simple operation, smaller sample size, higher sensitivity and higher throughput.Flow cytometry has been widely used in the detection and subgroup analysis of cytokines related to eye diseases, such as intraocular angiogenesis, intraocular lymphoma, retinopathy, cataract, uveitis, sarcoidotic uveitis, infectious intraocular inflammation, etc.Flow cytometry plays an increasingly important role in the pathogenesis research and targeted therapy of eye diseases.In this article, the application of flow cytometry in the examination of cytokines and cytology in ocular fluid for ocular diseases were reviewed.

AIM: To investigate the effect of intravitreal injection of anti-vascular endothelial growth factor (VEGF) drug Bevacizumab on connective tissue growth factor(CTGF) and pigment epithelium derived factor (PEDF) in proliferative membranes in patients with proliferative diabetic retinopathy (PDR).METHODS: From January 2015 to December 2016, 117 patients (126 eyes) with PDR were analyzed using the case-control study.The selected cases were randomly divided into two groups, respectively, Group A of 60 cases (63 eyes) and Group B of 57 cases (63 eyes).The Group A was treated with vitrectomy alone, while the Group B received intravitreal injection of 0.05mL/1.25mg bevacizumab before vitrectomy.The peeled epiretinal membranes in patients were stained and then the histopathological changes were observed for primitive cells and angiogenesis, the expression of CTGF and PEDF were tested.RESULTS: The expression of CTGF and PEDF in the proliferative membrane of the two groups were expressed in the cytoplasm.The Group A showed positive expression in 38 cases, the positive rate was 60.3%.Compared with Group A, the positive expression rate of CTGF in Group B (92.1%) was significantly higher (P<0.05).The positive expression rates of PEDF in the two groups were 90.5% and 95.2% respectively, and there was no significant difference between the two groups (P>0.05).CONCLUSION: In patients with PDR after intravitreal injection of bevacizumab, the retinal neovascularization is significantly reduced, which is conducive to vitrectomy.The positive expression rate of CTGF significantly increased in patients with PDR after intravitreal injection of bevacizumab, but there was no significant change in the expression of PEDF in the anterior membrane.

AIM: To study the effect of intravitreal injection of anti-vascular endothelial growth factor (VEGF) on best corrected visual acuity (BCVA) and multifocal-electroretinogram (mfERG) before and after treatment for choroidal neovascular disease.METHODS: A total of 264 patients (332 eyes) with macular neovascularization (MCNV) and idiopathic choroidal neovascular disease (ICNV) who underwent pathologic myopia from January 2015 to January 2017 were enrolled in this study.Intraocular pressure and BCVA, fundus using 90D front mirror and slit lamp detection, and the fundus photograph, OCT, ICGA and FFA angiography, mfERG detection were taken.One month after the drug, 1mo after the final treatment, we recorded BCVA, intraocular pressure and mfERG and so on.RESULTS: Ranibizumab was injected into the 254 eyes, and 78 eyes were injected with conbercept.There were 37 eyes injected once, 147 eyes were injected twice, 72 eyes were injected 3 times, 57 eyes were injected 4 times, 19 eyes 5 times.There were no significant differences on intraocular pressure between the two groups (P>0.05).The BCVA before treatment was significantly different compared with those 1mo after treatment and 1mo after the final treatment (P>0.05).The amplitude of Ring1, Ring2 and Ring4 increased after treatment, the difference was statistically significant.(P<0.05).The amplitude of Ring3 and Ring5 increased at 1mo after final treatment(P<0.05).CONCLUSION:Intravitreal injection of anti-VEGF drugs has a significant effect on BCVA and mf ERG in patients with choroidal neovascular disease and is safe.
