AIM: To assess the efficacy of topical Semaphorin 3A(SEMA3A) in the treatment of allergic ***: Experimental allergic conjunctivitis(EAC)mice model induced by short ragweed pollen(SRW) in 4-week-old of BALB/c mice, mice were evaluated using haematoxylin and eosin(H&E) staining, immunofluor-escence and light microscope photographs. Early phase took the samples in 24 h after instillation and late phase took the samples between 4 to 14 d after the start of treatment. The study use of topical SEMA3A(10 U, 100 U,1000 U) eye drops and subconjunctival injection of SEMA3 A with same concentration. For comparison, five types of allergy eyedrops were quantified using clinical characteristics.· RESULTS: Clinical score of composite ocular symptoms of the mice treated with SEMA3 A were significantly decreased both in the immediate phase and the late phase compared to those treated with commercial ophthalmic formulations and non-treatment mice. SEMA3 A treatment attenuates infiltration of eosinophils entering into conjunctiva in EAC mice. The score of eosinophil infiltration in the conjunctiva of SEMA3 A 1000 U-treated group were significantly lower than low-concentration of SEMA3 A treated groups and non-treated group. SEMA3 A treatment also suppressed T-cell proliferation in vitro and decreased serum total Ig E levels in EAC mice. Moreover, treatment of SEMA3 A suppressed Th2-related cytokines(IL-5, IL-13 and IL-4)and pro-inflammatory cytokines(IFN-γ, IL-17 and TNF-α)release, but increased regulatory cytokine IL-10 concentration in the conjunctiva of EAC ***: SEMA3 A as a biological agent, showed the beneficial activity in ocular allergic processes with the less damage to the intraocular tissue. It is expected that SEMA3 A may be contributed in patients with a more severe spectrum of refractory ocular allergic diseases including allergic conjunctivitis in the near future.

The natural history of cirrhosis varies and therefore prognostic prediction is critical given the sizable patient population. A variety of clinical prognostic indicators have been developed and enable patient risk stratification although their performance is somewhat limited especially within relatively earlier stage of disease. Molecular prognostic indicators are expected to refine the prediction,and potentially link a subset of patients with molecular targeted interventions that counteract poor prognosis. Here we overview clinical and molecular prognostic indicators in the literature,and discuss critical issues to successfully define,evaluate,and deploy prognostic indicators as clinical scores or tests. The use of liver biopsy has been diminishing due to sampling variability on fibrosis assessment and emergence of imaging- or lab testbased fibrosis assessment methods. However,recent rapid developments of genomics technologies and selective molecular targeted agents has highlighted the need for biopsy tissue specimen to explore and establish molecular information-guided personalized/stratified clinical care,and eventually achieve "precision medicine".

＜正＞Quantitative method of climate reconstruction was applied to the high - resolution （ average 30 years） pollen profile from Daihai Lake, Inner Mongolia, Northern China. Precipitation in the early to mid Holocene （ ca. 8 to 4 ka） was significantly higher than the late Holocene, showing that the average position of the monsoon limit was shifted to the more inland part of China. Within the error of the age model, the overall trend of the precipitation changes shown good agreement with the precipitation changes reported from the low latitude Chinese cave

＜正＞ This paper describes a robust speech documents retrieval system that uses voice input keywords. To solve the inevitable problems which arise when the input to the system is speech, i. e. misrecognition, a novel method was developed, where ,before the retrieval processing, unproductive keyword candidates are discarded by a grouping processing using the similarity between words and the recognition score of keywords. In retrieval experiments. we used the proposed method to retrieve Japanese broadcast news documents through voice keywords input to the system and showed its effectiveness.
