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 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

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.

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

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.

Objective To investigate the features of digital subtraction angiography(DSA) of meningioma and the application of therapy in preoperative embolization.Methods DSA in 36 cases with meningioma proved pathologically was performed.Of them,22 cases which the blood supply of tumor was mostly by external carotid artery were undergone external carotid artery embolization and surgical incision 3~10 days after embolization.Results Among 36 cases,the blood supply of tumor was only from external carotid artery in 9 cases,both of external and internal carotid artery supply in 25,and only internal carotid artery in 2.Among 22 cases undergone embolization of supplying artery the tumor stain absolutely disappeared in 16,evidently decreased in 6.22 cases undergone surgical incision after embolization,the tumors were wholly resected,average bleeding 150~500 ml during surgery.Conclusion The blood supply of meningioma can be only by external or internal carotid artery,or both.Preoperative cerebral angiographies and embolization are beneficial for the total resection of meningioma and reduction of bleeding during surery.

Objective To explore the effect of acupuncture and moxibustion combined with quadriceps exercise on osteoarthritis of knee joint. Methods 82 cases of knee osteoarthritis were randomly divided into the acup-moxibustion group (41 cases, treated with acup-moxibustion and quadriceps exercise treatment) and routine treatment group (41 cases). Lower limb ability of daily life respectively and knee pain of patients before and 30 days after treatment were evaluated. Results Clinical symptoms of patients in both groups were improved significantly after treatment. The acup-moxibustion group was better than traditional group in relieving pain and improving the lower limb ability of daily life (P<0.01). Conclusion The acup-moxibustion therapy combined with quadriceps exercise has preferable clinical curative effect on knee osteoarthritis.

To observe the dynamic change of parasites in the brains of BALB/c mice infected with Angiostrongylus cantonensis in order to explore its possible mechanism of pathogenesis', BALB/c mice infected with the III stage larvae of A.cantonensis were observed and killed in different times after infection. The number and distribution of parasites in the brains of the infected mice were observed microscopically and macroscopically. It was found that the larvae of A.cantonensis were distributed in the cerebrum and cerebellum of mice in accordance with the rule of parasitization of worms in the host, i.e.multiplication at first and then dropping in number. And the places where the parasites located were damaged due to mechanical action or inflammatory reactions. The time of onset of symptoms, such as ataxia and twitch was coincided with the dynamic changes in the brains of the infected mice.

This study was aimed to verify the chemical component cantharidin from Chinese blister beetle by LC-MS/MS. Components were first processed by HPLC to choose the appropriate separation conditions before LC/MS/MS analysis. Through the positive and negative ions pre-scan, positive ions scanning way was selected in the scanning of each separate component. The scanned maps were obtained and the relative molecular mass was deduced. The results showed that 8 types of cantharidin compounds were identified, including three isomers. It was concluded that LC-MS/MS was able to determine the chemical component cantharidin from Chinese blister beetle rapidly and accurately, which was existed in the body by the form of combined amino acid.
