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.

Aleutian mink disease parvovirus (AMDV) causes a persistent infection associated with immune complex disease, hypergammaglobulinemia, and high levels of antiviral antibodies. Despite the presence of an antibody, the virus is not cleared in vivo. Pre-existing antibodies may enhance viral infections, by Fc-receptor-mediated antibody-dependent enhancement (ADE), but the mechanism that underlies ADE has not been fully defined. Three models have been proposed, including: (1) interactions between antibody and FcR, complement C3 fragment and CR, or between C1q and C1qR, which promotes viral attachment to cells; (2) suppression of IFN-gamma-mediated host-cell antiviral gene expression by the upregulation of negative regulators of pathogen pattern recognition; and (3) the promotion of early IL-10 secretion. In addition, the role of cytokine IL-6 in ADE mediated disease development is discussed, to facilitate a better understanding of the pathogenesis of AMDV infection, as well as give insights into rational vaccine design approaches.

The relationship between acupuncture and stress is discussed from three aspects, including is it possible for acupuncture stimulation to be a stressor, whether acupuncture will start stress reaction, and whether acupuncture effects contain some stress factors. It is believed that correct acupuncture manipulation will not cause stress response, however, under some circumstances, such as inaccurate manipulation, improper treatment or patients who are very nervous but do not receive effective intervention, acupuncture is likely to cause stress response. Acupuncture-induced stress response is totally different from acupuncture anti-stress. The possible stress factors in acupuncture effect are explored, which can provide a new angle for the research on action mechanism of acupuncture. From the view of stress to review acupuncture treatment, there are three enlightenments: emphasizing on communication between doctors and patients, avoiding over-pursuit of deqi and focusing on analysis of the body constitution.
