Objective To investigate the necessity to test the hearing of patients whose initial symptom is tinnitus with pure tone audiometer. Methods To analyze the results of pure tone audiometer of 218 tinnitus patients.Results Among 218 cases of tinnitus patients,a total of 123 patients with abnormal hearing,among 95 cases of patients with normal hearing, except for 50 cases of tinnitus, no other cause of disease. Conclusion Among the normal hearing tinnitus patients, we should do further hearing test for them if they are not identified a clear cause of disease,such as auditory brainstem response,otoacoustic emission and other necessary checks to clear the reasons for tinnitus or the position of the unusual auditory system. It is important for early diagnosis and treatment of tinnitus. But the pure-tone audiometer should be a routine examination when tinnitus patients come for the first visit.

To explore the anti-tumor effect of immunotherapy with recombinant protein vaccine based on FGFR-1 of chicken (cFR-1) in a mouse Meth A fibrosarcoma model, tumor volume and survival rate of the mice were observed at a 3-day interval. Microvessel density (MVD) was detected by immunohistochemistry. Auto-antibodies against self-FGFR-1 were detected by Western blotting and ELISA, respectively. The anti-FGFR-1 antibody-producing B cells (APBCs) were detected by enzyme-linked immunospot (ELISPOT) assay. Eighteen days after inoculation of tumor cells, the tumor volume was significantly smaller in cFR-1-immunized group than in mouse FGFR-1 (mFR-1) immunized group and normal saline (NS) control group (P<0.05), and the survival time was significantly longer in cFR-1-immunized group than in the control groups (P<0.01). MVD was significantly lower in cFR-1-immunized group than in mFR-1-immunized group and NS group (16.8+/-5.6 vs 64.6+/-1.8 and 59.6+/-8.7, P<0.01). Antibodies against self-FGFR-1 were found in mFR-1-immunized group, the major antibody subclasses were IgG1 and IgG2b. Compared with the two control groups, the numbers of APBCs in cFR-1-immunized group were significantly increased (P<0.01) These results demonstrated that the cFR-1-related anti-angiogenesis protein vaccine could induce the production of auto-antibodies against self-FGFR-1, which futher inhibit angiogenesis and growth of solid tumor.

Phyllanthi Fructus is a highly unique medicine and food homologous item, which exhibits distinctive flavor, notable nutritional value, and abundant pharmacological activity. It has enormous potential in the creation of health products and pharmaceuticals. However, due to the unique laws of quality formation and transfer of Phyllanthi Fructus, its appearance, shape, chemical compositions, nutrients, and sensory flavors are frequently greatly influenced by botanical resources, the processing and storage conditions. As a result, the current quality evaluation model is difficult to meet the needs of Phyllanthi Fructus as a medicine and food homologous item in the development of diversified products. This paper constructs the hierarchical utilization mode of Phyllanthi Fructus based on its unique quality formation and transmission laws, explores the quality evaluation model for food-oriented use and medicinal-oriented use, respectively, and systematically describes the quality evaluation idea under diversified application scenarios. This paper aims to serve as a reference for the construction of a quality evaluation model suitable for the medicine and food homologous item of Phyllanthi Fructus.
