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.

Autoimmune pancreatitis is a chronic autoimmune-related pancreatitis.It is characterized by a high globulin, IgG~4 increased, anti-carbonic anhydrase antibody and anti-lactoferrin antibodies exist, diffuse swelling of the pancreas, a significant lymphocyte infiltration accompanied by fibrosis, multiple clinical manifestations , and sensitive to the hormone treatment.

BACKGROUND:Titanium materials have high mechanical strength, stable physical properties, good biocompatibility, and excelent corrosion resistance, which can be safely used in humans. OBJECTIVE:To compare the safety of mesh-like titanium aloy steel plateversus wire mesh in the repair of chest wal defects. METHODS:Eighteen patients with chest wal defects, 11 males and 7 females, with an age range of 19-65 years, were enroled. The 9 of 18 patients were subjected to repair with mesh-like titanium aloy steel plate, and the other 9 patients underwent wire mesh repair. At 1 week after repair, visual analog scale scores were measured in the two groups, and patient’s satisfaction on the thoracic appearance and incidence of complications were surveyed during the folow-up. RESULTS AND CONCLUSION: Al patients were folowed up for 1-7 years. During the folow-up, X-ray review displayed good thoracic stability and no fracture of titanium plate and wire mesh. Patients recovered wel from respiratory dysfunction, with unapparent chest wal deformity and high satisfaction rate of the thoracic appearance. Moreover, compared with the wire mesh group, the satisfaction rate of the thoracic appearance was significantly higher (P< 0.05), but the incidence of complications was significantly lower in the titanium plate group (P < 0.05). At 1 week after repair, the visual analog scale scores had no difference between the two groups (P> 0.05). These findings indicate that the mesh-like titanium plate has good biocompatibility and safety to effectively maintain the stability of the chest wal.

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 observe the efficacy of 25G vitrectomy for traumatic cataract.?METHODS:Retrospective analysis of 70 cases (70 eyes) of traumatic cataract treated by 25G vitrectomy with lensectomy from February 2013 to February 2015 in our hospital was made for the study.In the patients, there were 43 males ( 43 eyes ) , 27 females ( 27 eyes ) , aged from 22-51 years old with an average of 35.23±2.54 years, mean visual acuity was 0.10±0.03.They were all followed up for 6 -12mo postoperatively. Anterior segment, fundus, complications, best corrected visual acuity ( BCVA ) and intraocular pressure were observed during the follow - up. BCVA preoperatively, 1wk postoperatively, 1 mo postoperatively, 6mo postoperatively were compared.? RESULTS: All the patients underwent the surgery successfully, and visual acuity improved at different degrees. The differences of BCVA preoperatively compared with 1 and 6m postoperatively were all statistically significant ( P <0. 05 ). Postoperative complications:5 cases with corneal edema, 10 cases with ocular hypertension, 4 cases with ocular hypotension, 5 cases with retinal spotting.The symptoms improved after symptomatic and supportive treatment.? CONCLUSION: 25G vitrectomy with lensectomy is effective on treating traumatic cataract, with decreased operation risk, complications and improved visual acuity.

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.
