ABSTRACT

<p><b>OBJECTIVE</b>To investigate the clinical characteristics and treatment strategies of severe complications induced by esophageal foreign bodies.</p><p><b>METHODS</b>The clinical data of 44 patients with severe complications of esophageal foreign bodies treated from July 2004 to July 2014 were retrospectively analyzed. The type of complications was recorded.</p><p><b>RESULTS</b>The ratio of severe complications in patients with esophageal foreign bodies was 9.05% (44/486). The most common type of foreign body was animal bone, with a total of 34 cases (77.3%); Onset of the disease were 2-40 days, mostly above 6 days, accounting for 61.4%. Severe complications of esophageal foreign bodies included 16 cases (36.3%) of simple esophageal perforation or combined with esophageal regional inflammation, 14 cases (31.8%) of cervical abscess, 7 cases (15.9%) of abscess around esophagus, 3 cases (6.8%) of mediastinal abscess, one case (2.3%) of cervical subcutaneous emphysema, one case of tracheoesophageal fistula, one case (2.3%) of aortic fracture, and one case (2.3%) of subclavian artery pseudoaneurysm. Among the 44 patients with severe complications, 40 patients (90.9%) were cured and 3 patients (6.8%) died. One case didn't receieve treatment.</p><p><b>CONCLUSIONS</b>Occurrence of the severe complications induced by esophageal foreign bodies is closely related to the type of foreign bodies and time before presentation. Early diagnosis and prompt treatments for esophageal foreign bodies are crucial for preventing of severe complications.</p>

ABSTRACT

OBJECTIVE@#To observed the prevention efficacy of secretory otitis media after radiation therapy by the Myrtol Standardized Enteric Coated Soft Capsules.@*METHOD@#Sixty patients with nasopharyngeal carcinoma who Diagnosis without secretory otitis media before radiation therapy were divided into experimental group and control group, 30 cases in each group. After the start of radiation therapy ,the experimental group patients oral the Myrtol Standardized Enteric Coated Soft Capsules, each 0.3 g, 3 times a day, 7 days a course of treatment, oral the medication three months, the patients in the control group received no treatment. 3 months and 6 months after the end of radiation therapy, whether there is a difference comparison of experimental group and the control group in symptoms, signs, pure tone audiometry and tympanogram change.@*RESULT@#Seventeen patients (18 ears) (56.67%, 17/30) in the control group were suffering from secretory otitis media, 7 patients (7 ears) (23.33%, 7/30) in the experimental group were suffering from secretory otitis media. The difference between the two groups was statistically significant (P 0.05). 3 months after radiation therapy,the gas conductive hearing threshold of the experimental group is (25.6 +/- 3.0) dB HL, but the data in the control group is (40.7 +/- 5.0) dB HL. The difference between the two groups was statistically significant (P < 0.01).@*CONCLUSION@#Patients with nasopharyngeal carcinoma oral the the Myrtol Standardized Enteric Coated Soft Capsules before radiation therapy can effectively reduce the incidence of secretory otitis media after radiotherapy, it can prevent the occurrence of secretory otitis media.

ABSTRACT

OBJECTIVE@#To explore the regulative effect of expression of VEGF gene in nasopharyngeal carcinoma, and to discuss the future application of microRNA in the gene therapy for nasopharyngeal carcinoma.@*METHOD@#We constructed the recombination miRNA plasmid vectors which target VEGF gene and plasmids were transfected into CNE-2 cells by using Lipofectamine 2000 Reagent. The VEGF mRNA and VEGF protein were detected by reverse transcriptase polymerase chain reaction (RT-PCR) and Western blotting respectively. WST-8 assay was used to determine the inhibitory effect of microRNA on cell growth. Stable cell lines and wild type CNE-2 cell line were inoculated to subcutis of nude mice to establish animal models. The tumor growth and volume were observed.@*RESULT@#After the transfection of CNE-2 cells , the expressions of VEGF mRNA and VEGF protein were down-regulated at different degree. Whereas, CNE-2 cell growth showed no change by observation of fluorescence microscopy, and cell proliferation was not inhibited in WST-8 assay. However, in vivo, growth of xenograft was inhibited in preliminary experiments of nude mice.@*CONCLUSION@#By miRNA plasmid constructed artificially, miRNA can effectively interfere nasopharyngeal carcinoma cells by down-regulating the expressions of VEGF gene, therefore can inhibit the growth of tumor xenografted in vivo. Future application of microRNA in the gene therapy of nasopharyngeal carcinoma might be expected.

ABSTRACT

OBJECTIVE@#To study the killing effect of suicide gene CDglyTK combined with GCV or 5-FC on the human laryngeal carcinoma Hep-2 cell line in vitro.@*METHOD@#Constructed plasmid pcDNA3.1 (-) CMV. CDglyTK was verified by enzyme digestion of Xho I /Hind III and automatic sequence analysis, then it was introduced into Hep-2 cells by electroporation to yield cells expressing CDglyTK stably after selecting with G418(400 ng/L) for 14 da. The expression of CDglyTK mRNA in transfected Hep-2 cells was tested by RT-PCR. Compared with Hep-2 cells transferred with pcDNA3.1(-), in vitro chemosensitivity of CDglyTK-expressing Hep-2 cells to 5-FC, GCV or 5-FC + GCV was detected by MTT assay.@*RESULT@#The recombinant plasmid contained full-length coding region sequence of CD and TK gene. A anticipated 707 bp fragment was amplified from total RNA of CDglyTK-expressing Hep-2 cells by RT-PCR and a fusion protein of 59 000 was detected in cell extract from transfected Hep-2 cells. In vitro study growth of CDglyTK-positive Hep-2 cells were inhibited by 5-FC, GCV or 5-FC + GCV respectively, and the antitumour effect of 5-FC + GCV is superior to 5-FC or GCV.@*CONCLUSION@#CDglyTK may be a candidate for treating human laryngeal cancer.
