Purpose:To evaluate the efficacy of bladder p re servation treatment by concurrent neoadjuvant intra-arterial chemotherapy, radi otherapy and transurethral resection for patients with bladder cancer with muscl e invasion. Methods:Thirteen patients who were unfit for or unwilling to re ceive radical cystectomy were enrolled in this study. All patients had muscle in vasive transitional cell carcinoma of bladder(T 2-T 3). Patients were treated with neoadjuvant intra-arterial chemotherapy, radiotherapy and transurethral r esection. The chemotherapy regimen consisted of cisplatin 80 mg, epirubicin 50 m g and fluorouracil 1 g/camptothecin 30 mg. The average dose of radiotherapy was 30-50 Gy. Results:At the end of neoadjuvant therapy, 1 patient (7.69%) sh owed a complete response and 12 patients (92.31%) showed partial response; tran surethral resection was performed for residual tumors. All patients completed th e treatment and showed good tolerance. With a median follow-up of 26.46 months, local recurrence or distant metastasis occurred in 5 patients (38.46%). Recurre nt tumors were treated with transurethral resection or systematic chemotherapy a nd radiotherapy. Conclusions:concurrent neoadjuvant intra-arterial chemotherapy , radiotherapy and transurethral resection is a feasible and promising treatment for patients with bladder cancer with muscle invasion.

The relationship between probiotics and host intestinal immune system was reviewed. Then, as a new immunomodulator, the mechanisms and clinical uses of probiotics were discussed.

Many microbial pathogens,including those responsible for major enteric infections,exploit oligosaccharides that are displayed on the surface of host cells as receptors for toxins and adhesins. Blocking crucial ligand receptor interactions is therefore a promising therapeutic strategy. One approach is to express molecular mimics of host receptors on the surface of harmless recombinant bacteria that can survive in the gut. These recombinant probiotics bind bacterial toxins in the gut lumen with very high avidity,thereby preventing disease.

Fermentation property and kinetic analysis of the inhibition of in vitro growth of pathogenic Escherichia coli K88, O138 by Lactobacillus intestinalis isolated from porcine intestine mucus were investi-gated. The results of fermentation showed that L1 result in a pH of 3.90 within 12 h and a large amount of lactic acid production, with the concentration of 104.08 mmol/L. Kinetic analysis of the antibacterial activity of L1 metabolic product toward K88, O138 showed that CFUS display strong antibacterial activity toward K88, O138; the antibacterial activity of L1 CFUS was higher than the lactic acid control samples and was mainly due to the production of lactic acid; K88, O138 had the tolerance property toward pH 4.5.

BACKGROUND: Research shows that the auditory brainstem response (ABR) wave amplitude of tinnitus patients often act as big Ⅲ small Ⅴ.Tinnitus masking is a therapy of tinnitus, then how dose the ABR change in the process of tinnitus masking?OBJECTIVE: To observe the changing characteristics of ABR in patients with tinnitus as well as the changing rules of ABR after tinnitus masking.DESIGN: Case-control and self-control.SETTING: Department of Otorhinolaryngology, First Hospital of Jilin University.PARTICIPANTS: Continuous tinnitus group: 63 cases (68 ears) were selected from the Clinic of First Hospital of Jilin University from March 1999to October 2001. Control group: 10 cases (20 ears) of normal hearing youth (20-23 years old). All subjects received the examination and treatment voluntarily.METHODS: The ABR was firstly detected in tinnitus patients (foreheadmastoid conducting method was adopted), and examination of tinnitus as well as tinnitus masking test (masking for 5 minutes) were respectively conducted, immediately after that, the ABR was detected to do control-observation with the control group.MAIN OUTCOME MEASURES: ①The characteristics of ABR in patients with tinnitus. ②Effects of tinnitus masking on the amplitude wave of ABR, which was divided into positive group in residual inhibition test and negative group in residual inhibition test for analyzing.RESULTS: A total of 83 subjects were involved in the analysis of results.①The amplitude wave of ABR in youth of normal hearing were small Ⅲ big Ⅴ, whereas that in 22 ears (32.4％) out of 63 subjects (68 ears) were big Ⅲ smallⅤ, in which 17 ears were of patients positive residual inhibition test, and 5 were of negative.②After tinnitus masking therapy, 10 ears out of 17 ears of patients positive in residual inhibition test turned from big Ⅲ small Ⅴ to small Ⅲ big Ⅴ, and the wave amplitude of Ⅲ wasre duced in 3 ears, while the ABR in 2 ears out of 5 ears of negative patients turned to small Ⅲ bigⅤ, and there were no changes in other 3 ears.CONCLUSION: Tinnitus masking therapy can convert the abnormal ABR wave amplitude in patients with tinnitus to normal, which will be taken as the objective index in judging whether it is positive in residual inhibition test.

Objective To explore the imaging characteristics of testicular germ cell tumors and to improve the MRI diagnostic level. Methods MRI and clinical data of 25 cases confirmed testicular germ cell tumor by pathological examination were retrospectively analyzed. All the 25 cases were performed plain scan of MRI,and 16 patients underwent MRI enhanced scan.The size,morphology,signal intensity, adjacent structures,enhancement figure and tumor supplying artery were assessed and the histopathological findings were servered as the standard of reference.Results In the all 25 testicular germ cell tumors,10 cases were seminoma,8 cases showed homogeneous low signal intensity,2 cases of seminoma were low signal intensity on T2 WI,furthermore 5 cases performed poor nodular enhance-ment,2 cases performed homogeneous enhancement,4 cases performed fibrous septa enhancement.4 cases were yolk sac tumor ap-peared equal-low signal on T1 WI,slightly high signal intensity on T2 WI and progressive enhancement.Mature teratoma,pidermoid cyst and mixed germ cell tumor were 3 cases respectively,the MRI demonstrated mixed low signal intensity on T1 WI and mixed high signal on T2 WI.2 cases were embryonal carcinoma demonstrated middle-low signal intensity on T1 WI,and mixed low signal intensity on T2 WI.The two cases revealed bleeding signal intensity and septa enhancement.Conclusion MRI can be used to diagnose germ cell tumors with high accuracy,and provides essential information for pathological type,stage and differential diagnosis.

Lactic acid production of twelve strains of LAB isolated from broiler intestine and tolerance property of three strains were investigated. The results of lactic acid production showed that among all strains K6 exhibited the most rapid production during the first twelve hours, the seconds were K9 and C1; D17 exhibited the highest production of lactic acid by twenty-four hours, C1 exhibited the highest production of lactic acid by forty-eight hours. The pH values in three strains of K9、D17 and C1 culture showed the fast decline during the first twelve hours, with the final values significantly lower than those of other strains cultures. The results of tolerance property showed that the survival counts of C1could be detected when pH value was at 2 after three hours, but the survival counts of D17 and K9 could not be detected after one hour. When pH value was at 2.5 after three hours ,the survival counts of C1 declined from 10~ 8.2 /mL to 10~ 4.8 /mL, K9 from 10~ 8.2 /mL to 10~ 4.6 /mL, the survival counts of D17 could not be detected. 0.08% bile had few effects on the survival counts of three strains; when incubated in the medium with 0.40% bile, the survival counts of C1 declined from 10~ 8.4 /mL to 10~ 6.5 /mL,D17 from 10~ 10.3 /mL to 10~ 7.5 /mL, and K9 from 10~ 9.8 /mL to 10~ 7.7 /mL. When the group treated with 37℃ for 20 minutes was served as the control, the survival counts of C1 and K9 was not detected when treated with 80℃, but the survival counts of D17 were 10~ 4.9 /mL, when treatment with 65℃ the survival counts of C1 and K9 decreased significantly .
