AIM: To observe the comparison of vitrectomy combined drug therapy ( Ranibizumab injection ) and single vitrectomy for proliferatived diabetic retinopathy ( PDR ) and the influence of the curative effect and prognosis of patients.
METHODS:In this study, 112 cases (125 eyes) with PDR were selected and randomly divided into experimental group and control group ( n= 56 ) . Fifty-six cases ( 61 eyes ) in experimental group were injected by drug therapy of 0. 5mg ranibizumab and received vitrectomy;In control group, 56 cases ( 64 eyes ) were received single vitrectomy. The intraoperative and postoperative differences of clinical indicators were analyzed in two groups.
RESULTS: The average operation time, intraoperative electric coagulation hemostasis rate and iatrogenic hiatal incidence of the experimental group were lower than that of the control group:(95. 00±13. 00) min vs (133. 00±14.5) min, 11% vs 34%, 5% vs 20%, respectively (P<0. 05). The anterior chamber and vitreous body cavity hemorrhage rate within postoperative 1mo in the experimental group were lower than that of the control group:7% vs 23%, 5% vs 12%, respectively (P<0. 05). The postoperative visual acuity of experimental group was better than that of the control group:0. 375±0. 210 vs 0. 261±0. 170, respectively (P<0. 05).
CONCLUSION: Patients with PDR injected with ranibizumab in vitreous cavity before vitrectomy can effectively reduce the operation time, less intraoperative blood loss, the incidence of iatrogenic hiatus, and intraoperative and postoperative complications. The postoperative visual acuity was better than before.

Objective To investigate the long-term efficacy of transendocardial injection of vascular endothelial growth factor (VEGF) into ischemic porcine myocardium.Methods Thirty pigs were divided into two groups:control group and treatment group (15 each).A angioplasty balloon was used to occlude the left anterior descending coronary arteries of the animals to reproduce a porcine myocardial ischemic model.Blank plasmid (control group) or constructed pIRES2-EGFP-hVEGF165 eukaryotic expression plasmid (treatment group) was directly injected into the ischemic myocardium through an transendocardial injection catheter of NOGA system,respectively.Before and one year after injection,left ventricular electromechanical mapping (LVEMM) was used to detect local linear shortening (LLS) and unipolar potential (UpV);M-mode local wall motion,cycle variation of integrated backscatter (CVIB) and left ventricular ejection fraction (LVEF) were detected by ultrasonagraphy.One year later,the animals were sacrificed for the observation of the capillary formation in myocardial tissue with immunohistochemical staining.Results One year after injection,as compared with that of control group,local linear shortening (LLS) showed a significant increase (P0.05),and ultrasonagraphy showed better heart function in the treatment group (P

Objective To evaluate the damage to the brochial plexus produced by pulsed radiofrequency (PRF)and radiofrequency thermocoagulation(RFTC).Methods Fifty-five male Wistar rats weighing 250-300 g were randomly divided into 3 groups:groupⅠPRF(n=25):groupⅡRFTC(n=25)and groupⅢnormal control(n=5).The animals were anesthetized with intraperitoneal chloral hydrate.The left brochial plexus was exposed and PRF or RFTC was applied to the left brochial plexus.The voltage and current of the minimal stimulation which elecited muscle twitching and the impedance before and after operation were recorded in group PRF and RFTC.The nerve function was scored according to Tarloo(0=flaccid paresis,5=normal gait)before and at 3d after operation.The animals were killed and the left brachial plexus was removed immediately and at 1, 7,14,30 d after operation(n=5 at each time point)for determination of histopathological changes using microscope.Results The impedance and Tarlov score were significantly decreased after operation as compared to the baseline values before operation in group RFTC and were also significantly lower than in group PRF. Microscopic examination showed that the myelinated nerve fibers exhibited Wallerian degeneration and axon regeneration and the cytochondria in cylindraxile were severely injured or disappeared in group RFTC.The myelinated nerve fibers and the cytochondria in cylindraxile were significantly less injured after operation in group PRF than in group RFTC and returned to normal at 7 d and 30 d respectively.Conclusion The injury to brachial plexus produced by PRF is slighter than that produced by RFTC.

Objective To establish a stable cell line secreting human IgE Cε2-4 protein, and in-vestigate the binding capacity of receptor FcεR Ⅰ Methods The E24 gene was derived from SKO-O07 cell line, and was then cloned into pcDNA3.1 (+) (signal peptides were synthesized and fused at the 5'-end of E24 gene) or pCMV-L vector. After transient transfection into 293T cell, the secreted F24 protein was ana-lyzed by sandwich ELISA. The best vector was chosen to be transfected into CHO cells with LipofectAMI-NETM 2000 reagent. After being selected by G418 and subcloned three times by limited-dilution method, two stable cell lines were established. E24 gene was amplified by RT-PCR, and the E24 protein in the superna-tant was identified by ELISA. Besides, the binding capacity of FceR ⅠⅡ was analyzed by flow cytometry method. Results Three mammalian expression vector SP-E24-F3. 1, SP lI-E24-P3.1 and E24-PL were constructed and transient transfected to 293T cells. The output of E24 protein in the supernatant were 19.1, 19.4 and 8.7 μg/ml, respectively. Then the vector SP IX-E24-P3.1 was transfected into CHO cells. Final-ly, two single clones secreting E24 protein were stably obtained. The output of E24 were all at least 25 μg/ml. RT-PCR could detect the E24 gene from one of the two clones. Furthermore, flow cytometry results showed that E24 could bind the receptor in a dose-dependent manner. Conclusion Two stable cell line se- creting E24 protein were obtained, while E24 could specifically bind FcεR Ⅰ.
