ABSTRACT
Neurogenic tumors located in the posterior mediastinum, generally require surgery which be confronted with greater risk,therefore, to design the best surgical approach and surgical methods is essential. A 67-year-old female patient had pharyngeal foreign body sensation and dysphagia. Thyroid ultrasound showed the right thyroid had a little nodule, and the left thyroid had a hypoechoic lumps. Neck enhanced CT showd mediastinal mass, esophageal tumor origin or stromal tumor? We used the jugular approach to resect the tumor which eventually diagnosed as schwannoma. The meditational benign tumor with an envelope easy to peel can employ the jugular approach to resect it completely.

Objective To explore the application effect of hyperbaric oxygen ( HBO ) in the treatment of refractory peptic ulcer .Methods Clinical data of 259 patients with refractory peptic ulcer were retrospectively ana-lyzed.According to whether received HBO therapy , these patients were divided into the HBO group ( n=127 ) and control group(n=132).The total effective rate,Helicobacter pylori(Hp) eradication rate and relapse rate of the two groups were compared .Results The total effective rate ,Hp eradication rate of the HBO group were 93.7%,92.1%, respectively,which were significantly higher than 65.2%,56.1% of the control group (χ2 =31.97,7.32,all P<0.05).The relapse rate of the HBO group was 8.4%,which was significantly lower than 33.3%of the control group (χ2 =12.51,P<0.05).Conclusion HBO combined with conventional drug in the treatment of refractory peptic ulcer has significant effect .
ABSTRACT
Objective To investigate the correlation between plasma D-dimer with delayed encephalopathy (DE) in patients with acute carbon monoxide poisioning(ACOP).Methods According to the severity of disease,100 patients with ACOP were divided into mild group (27 cases),moderate group (31 cases),severe group (42cases).And depending on whether DE occured,all patients were divided into DE group(20 cases) and no DE group (80 cases).4 venous blood samples were obtained separately from each subject in 1,7,14 days after their admission to hospital by using latex immunoturbidimetry.The levels of blood plasma D-dimer of patients in each group were detected by immune turbidimetry and analyzed,1th,7th and 14th day after admission.Results The plasma D-dimer level of the mild group at different time points was in the normal range,and the difference was not statistically significant(all P ＞ 0.05) ;The plasma D-dimer level of the severe group and moderate group was significantly higher than that of the mild group(all P ＜0.01),and it reached a peak in one week(7 days),and showed a downward trend after two weeks(14 days).The DE all occurred in the moderate and severe group.The plasma D-dimer levels of the DE group were higher than those of no DE group from admission to the 7 th and 14 th day (all P ＜ 0.01).Conclusion The dynamic monitoring plasma D-dimer is helpful in assessing to the severity and prognosis of ACOP,and could surpport positive clinical significance for the prevention and treatment of DE.
ABSTRACT
Objective To study the therapeutic efficacy of combined interventional chemotherapy and intravesical instillation of mitomycin on preventing bladder cancers from recurring after local ablation. Methods 28 patients with superficial bladder cancers were randomized into combined interventional chemotherapy and intravesical instillation of mitomycin or intravesical instillation of mitomycin alone for preventing recurrence after local ablation.The result was assessed by ? 2 test. Results The patients have been followed up for 12～26 months (mean 21 months).1 case has had tumor recurrence in the combined modality therapy group and 4 in the intravesical instillation alone group,the tumor recurrence rate being 7% (1/14) and 29% (4/14) respectively(P
ABSTRACT
This study was designed to investigate modulation of phosphorothioate oligodexynucleotides of laminin receptor on MMP 2 and MMP 9 gene expression in human bile duct carcinoma cells. Treated with a concentration of 12?mol/L LNR AS OD in cuture medium, the relative MMP 2 and MMP 9 mRNA level at 72h in human bile duct carcinoma cells was evaluated by reverse transcriptase polymerase chain reaction. The results showed that the expression of MMP 2 and MMP 9 dropped obviously by AS OD group as compared with control group. The relative expression level of MMP 2 and MMP 9 gene mRNA decreased about 33 2% and 23 9% respectively. It is suggested that LNR AS OD is the regulator of MMP 2 and MMP 9 gene expression. It can decrease MMP 2 and MMP 9 gene expression in human bile duct carcinoma cells. Understading the regulation of MMP 2 and MMP 9 gene expression in human bile duct carcinoma cells might contribute to the development of a new preventive and theraputic strategy for tumor invasiveness.
ABSTRACT
To investigate the expression of laminin receptor in different bile duct carcinoma cell strains, a peritoneum infiltration screening model was established to screen out the different metastatic cell strains of bile duct carcinoma. Invasive experiments in vitro were adopted to validate the results. The difference of LNR expression was compared both in the high and low cell strains by flow cytometry analysis. The results showed that by using the peritoneum infiltration screening model, high and low metastatic QBC939 cell strains were successfully screened out. Invasive experiments in vitro also proved that the invasive ability of high cell strain was stronger than that of the low one. The positive rate of LNR in high strains (36 36?9 22)%was higher than that in the low ones(13 17?3 43)%, and the difference was significant( P
