Purpose　To evaluate the clinical safety of ionic contrast media made in china and compare with nonionic contrast media being imported. Methods　Among contrast-enhanced CT 1096 cases, 76% meglumine diatrizoate were administed in 864 cases and ultravist in 232 cases , comparative studies on adverse drug reactions(ADRs) and image quality were performed. Results　In 76% meglumine diatrizoate group , the prevalence of overall and mild -middle ADRs was higher than in the ultravist group , the prevalence of severe and potentially life-threatening ADRs was approximate in the ultravist group , the image quality was well than in the ultravist group.Preventive inoculation alleviated ADRs at all levels. Conclusion　Ionic contrast media made in china was safe and effective in patients without hyperthyroidism after preventive inoculation.

Objective To investigate the action mechanism of microRNA‐152(miRNA‐152) in the cisplatin(DDP) resistance process in non‐small cell lung cancer (NSCLC) .Methods The miRNA‐152 level in NSCLC cell line A549 and its cisplatin‐resistant cell line A549/DDP was detected by the real time quantitative PCR(qRT‐PCR) .miRNA‐152 mimic was transfected for increasing the intracellular miRNA‐152 level in A549/DDP .The MTT assay ,inverted miroscope technique and flow cytometry were adopted to observe the effect of up‐regulating miRNA‐152 on cell proliferation inhibition and apoptosis ,meanwhile ,the level changes of intra‐cellular Bcl‐2 and NF‐κB were also observed by adopting qRT‐PCR and Western blot .Results The low expression of miRNA‐152 and the high expression of Bcl‐2 and NF‐κB were found in A549/DDP cells .Up‐regulation of miRNA‐152 enhanced the inhibitory effect of DDP in A549/DDP cells .Furthermore ,after up‐regulating miRNA‐152 ,the inhibiting rate and apoptosis rate of A549/DDP cells caused by DDP were significantly higher than those in the cells without up‐regulating miRNA‐152 ,the difference was statisti‐cally significant(P<0 .05) .In addition ,miRNA‐152 mimic transfection significantly decreased the expression of Bcl‐2 and NF‐κB in A549/DDP cells .Conclusion Low expression of miRNA‐152 may induce the resistance of NSCLC to DDP ,miRNA‐152 could medi‐ate the sensitivity of NSCLC cells to DDP via regulating Bcl‐2 and NF‐κB levels .

Objective To evaluate the clinical features, diagnosis, and outcome of the treatment of cytomegalovirus (CMV) retinitis, and the relationship between CMV retinitis and acquired immunodeficiency syndrome (AIDS). Methods A total of 95 eyes of 56 patients with cytomegalovirus retinitis and AIDS were studied. The fundus feature, visual acuity and CD4 + T lymphocyte counts were analyzed and the follow up periods ranged from 2 weeks to 18 months. Results Before the definitive diagnosis of CMV retinitis, the courses of AIDS were 4 to 26 months in all patients. In the initial examination, the granular form of CMV retinal lesion was noted in 55 eyes (57%) in which retinal lesion of 46 eyes was peripheral. The fulminant form of CMV retinitis of 25 eyes (26%) was found in the posterior pole and consisted of densely opaque retinal lesions with blotchy hemorrhage and vasculitis. The overlap between these two presentations was noted in 15 eyes. Papillitis was observed in 7 eyes of CMV retinitis in this series of patients. The visual acuity ranged from finger counting to 0.5. The patients with extensive CMV retinitis or CMV retinitis in the posterior pole got poorer vision. The CD4 + T lymphocyte counts of 30 patients was 0 30 (mean, 15?9/?l), and the survival time ranged from 2 weeks to 18 months (mean, 6.4?3.3 months). The vision was improved and CD4 + T lymphocyte counts was significantly higher in the group treated with ganciclovir, and progression of CMV retinitis occured and the vision decreased in the non treated group. Conclusion CMV retinitis is the most common intraocular complication in patients with AIDS. Diagnosis of CMV retinitis is based on the characteristic of necrotizing retinitis which was typically associated with retinal hemorrhage and vasculitis. Ganciclovir is effective for the treatment of CMV retinitis.

Objective To discuss the spiral CT features of lymph node metastasis in advanced gastric cancer, and to investigate the correlation between spiral CT features and pathologic results. Methods Spiral CT scan and triphasic enhancement spiral CT scan were performed in 59 patients with advanced gastric cancer before operation. Results ①The pathologic metastatic rate of lymph node in gastric cancer was high when the lymph nodes were nubby-mixed, prominently enhanced, unsymmetrical enhanced and ≥9 mm in diameter on spiral CT (P<0.05). ②The detection rate of lymph node metastasis with spiral CT was high when carcinoma tissues were poorly differentiated, Borrmann Ⅲ+Ⅳ, T3-4 staging and TNM Ⅲ+Ⅳ staging. Conclusion The spiral CT features of lymph node (distributing type, size, enhanced degree, enhanced mode and staging) can reflect the pathologic characteristics of lymph node metastasis in gastric carcinoma. Pathologic characteristic of gastric tumor determines the detection rate of lymph node metastasis on spiral CT. The accuracy of CT to diagnose lymph nodes metastasis will be improved by integrating the spiral CT features of both gastric tumor and lymph node.

Objective:To summarize the complications' prevention and nursing experience for patients after autologous transplantation of the microvascular submandibular gland for severe keratoconjunctivis sicca.Methods:Retrospective analysis of 141 patients(151 sides) after autologous microvascular submandibular gland transfer operation was undertaken to record the timing and incidence of major complications and to summarize the nursing experience.Results: The main complications after the transplantation were: vascular crisis,catheter obstruction,salivary fistula and temporary paralysis of hypoglossal nerve.Related nursing measures in response to these complications were discussed.Conclusion:Targeted nur-sing interventions for patients with autologous transplantation the submandibular gland have a positive effect on the prevention of the surgical complications.

Objective To evaluate the diagnostic value of TNM staging of gastric carcinoma with triphase incremental helical CT.Methods Triphase incremental helical CT of the stomach with water-filling method were performed in 101 patients with gastric carcinoma.Results (1)The accuracy of T-staging,N-staging and TNM staging was 81.8%,72.9% and 80.2% respectively.(2)Demonstrating multilayered structure of the normal gastric wall in the arterial parenchymal-phase was advantageous to improve the accuracy of estimating the depth of tumor invasion (?
