Objective To investigate the difference of C reactive protein level detected by immunity transmission turbidity and dry immunofluorescence.Methods The clinical data of 56 patients with various kinds of infectious diseases who were treated in our hospital from September 2012 to January 2014 was retrospectively analyzed.Results The levels of C reactive protein in the obser-vation group detected by immunity transmission turbidity and dry immunofluorescence were significantly lower than those in the control group (P <0.05),and the positive rate of C reactive protein was significantly higher than that in the control group(P <0.05).Conclusion The levels of C reaction protein detected by immunity transmission turbidity and dry immunofluorescence in pa-tients with a variety of acute infectious diseases show no significant difference,suggesting that immunity transmission turbidity can be used as an alternative to dry immunofluorescence.

Objective: To investigate the effects of hexamethylene bisacetamide (HMBA) on apoptosis and the expression of bcl-2 in human mucoepidermoid carcinoma cell line MEC-1. Methods:MEC-1 cells were oxposed to 2 mmol/L HMBA or 1 mg/L 5 -Flourouracil (5 -FU ) for 72 hours. A poptosis index, the expression of bcl-2 protein and bcl-1 mRNA were determined by morphologic observation, terminal dUTP nick and labeling(TUNEL) stain, immunohistochemistry, in situ hybridization and image analysis. Results: Apoptosis indexes(%) in HMBA treated. 5-Fu treated and control cells were 68.5, 23.6 and 2.3 respectevely. The expression of bcl-2 protein and bcl-2 mRNA in HMBA treated cells was higher than in 5-Fu treated or the control cells(p

Objectives: To observe the efficacy of semiconducted laser photocoagulation on diabeticretinopathy(DR).　Methods: Retrospective analysis of 206 eyes from 140 patients receiving semiconducted laser photocoagulation therapy for DR.　Results:One hundred and eleven eyes were treated with PRP, 95 eyes were treated with mild-PRP. Visual acuity was increased by 1～3 lines in 82 eyes(35%), not changed in 94 eyes(46%) and decreased in 30 eyes(19%). On Fundus fluorescein angiography(FFA) 3 months later, new vessels shrinked and retinal edema recovered in most cases, but in 10 eyes, new vessels and small nonperfusional areas still could be seen after the treatment, which was treated again.　Conclusions: Timely and proper laser photocoagulation is an important treatment for DR, FFA is an essential guidance for this procedure.

Objectives:To observe the efficacy of doubling frequency laser for central retinal vein occlusion.　Methods:Twelve cases(13 eyes) of central retinal vein occlusion were treated with doubling frequency laser,4 eyes underwent panretinal photocoagulation, 9 eyes underwent regional retinal photocoagulation. The treatment varied from 1～3 times. Two cases received supplemental photocoagulation after reexamination. Fundus fluorescein angiography was performed in all the cases before and after the treatment and the results were compared.　Results:Laser spots were regular in perfusion area, pigment epithelium atrophy was mild and no fluorescein leakage was found at the border of nonperfusion area in the 9 eyes receiving regional photocoagulation treatment. Among the 4 eyes treated with panretinal photocoagulation, 2 eyes revealed neovascular atrophy at the posterior pole area; no fluorescein leakage was found and cystoid macular edema subsided. Another 2 eyes revealed neovascular regression and a little fluorescein leakage which needed supplemental photocoagulation. No neovascular increasing, perfusion area expanding or fluorescein leakage worsening were seen.　Conclusions:Laser therapy does not increase the central visual acuity but it dose help the absorption of retinal edema, hemorrhage and exudation, prevent the occurrence of proliferative vitreoretinopathy or neovascular glucoma and is protective to the present visual acuity.

Objective: To observe the curative effectiveness of laser therapy in 114 cases(120 eyes) posterior capsular opacity after intraocular lenses implantation in children.Methods: When the after-cataract appear,laser therapy should be performed as soon as possible.Under conscious condition,enable the children to cooperate maximally;short effect and mild mydriatic to dilate the pupil,a 4 mm diameter transparent zone in central was made allowing for satisfactory visual performance;Began with low energy(0.4 MJ) and increased progressively according to individual reaction,total energy was 20-30 MJ every time. Results: All the eyes' visual acuity recovered to the best level prior to posterior capsular(opacity) occurrence,corrected visual acuity 0.1-0.4 in 58 eyes,0.5-0.8 in 54 eyes,1.0 in 8 eyes.90 percent were succeed in one laser shot,no intraocular lenses damage was found in slit lamp microscope examination.Conclusion: laser can resect the posterior capsular opacity effectively,improve the visual function of the affected eye.Assisted with amblyopia treatment, laser capsulotomy play an important role in visual function reconstruction in these patients.

Objective:To study the effect of Slit-Robo signal on the proliferation of human oral squamous cell carcinoma line Tb. Methods:The expression of Slit and Robo protein was measured with Western blot. After the addition of the monoclonal antibodies (mAb) of R5 against Robo1 receptor extracellular domain, the changes of cell proliferation were studied by MTT assay and clone formation assay,the expression of PCNA was measured with immunohistochemical staining. Results:Western blot showed that Slit and Robo proteins were expressed in Tb cells. The proliferation rate of Tb cells decreased and the expression of PCNA decreased after the addition of R5 mAb. Conclusion:Slit-Robo signal may regulate the proliferation of Tb cells by up-regulation of PCNA.

A molecularly imprinted film ( MIF) was prepared on the surface plasmon resonance ( SPR) sensor chip for the detection of testosterone. The nanometer imprinted film was synthesized by surface grafting approach. First, the gold sensor chip was modified with an iniferter of benzyl diethyldithiocarbamate to create the “grafting from” polymeric surface. Grafting of the MIF onto the SPR chip was subsequently achieved through ultraviolet light-initiated copolymerization of methacrylic acid ( functional monomer ) and ethylene glycol dimethacrylate ( crosslinker ) in the presence of testosterone as a model template. The template molecules were then removed to form a MIF with specific recognition sites for testosterone. With this iniferter technique , self-aggregation in the reaction solution phase was avoided and grafting polymerization was confined to the exterior of the chip surface. The grafting process was implemented by in situ monitoring with SPR, which permitted the thickness of the film to be easily and strictly controlled. The chip surface modified with a testosterone-imprinted film was characterized by the methods of polarization modulation infrared reflection absorption spectroscopy ( PM-IRRAS ) and atomic force microscopy ( AFM ) . According to the results, testosterone-imprinted film modification of the SPR chip was achieved by the distribution of numerous homogeneous, nanoscale holes on the surface. The testosterone-imprinted film was applied on a SPR sensor chip for the detection of testosterone in the range of 2 . 5 í 10-16 to 2 . 5 í 10-6 mol/L in acetonitrile with the lowest determining concentration of 2. 5 í 10-16 mol/L. Adsorption experiments showed that there were two kinds of binding sites in the MIF, and the linear correlations between the changes in reflectivity and the concentration of testosterone were y=19. 69 + 1. 21x(R2=0. 9913) and y=11. 5 + 0. 45x(R2=0. 9895), respectively. Control experiments utilizing estradiol, estriol, and progesterone as analogues showed impressive selectivity and specificity for testosterone determination. The testosterone-imprinted film reproducibility was evaluated with five cycles of rinsing-rebinding and the RSD was 16 . 8% and 11 . 2% for the SPR angle changes in rinsing and rebinding respectively, demonstrating that the MIF-modified SPR sensor had good reproducibility and repeatability. Finally, the SPR sensor was successfully used to determine testosterone in artificial urine samples with recoveries from 85 . 2% to 92 . 8%.
