Here we summarize the progress of salmon calcitonin's heterogenous expression in prokaryotic and eukaryotic expression systems as well as the amidation of C-terminal. Both the biological activity of salmon calcitonin and the biologic expression system can be improved by genetic engineering techniques.

本文综述了鲑鱼降钙素基因在大肠杆菌、链霉菌、乳酸杆菌和蓝藻等原核细胞，在酵母、昆虫、动植物等真核细胞中异源表达的研究进展，以及通过基因工程的方法能够改进生物表达系统，提高鲑鱼降钙素活性的动态。

In contrast, the levels of glutamate and alanine decreased, the level of ghitamine increased in the ipsi-lesional MVN, and the level of glutamate decreased in the contra-lesional MVN of rats 2 weeks after infusing 10 mg arsanilic acid into the tympanic cavity to obstruct m-periphery vestibular organ.

结果提示，单侧迷路破坏后双侧MVN区氨基酸含量立即失去平衡，随着前庭代偿的进展，此差异减少，但是在前庭代偿后却出现双侧前庭核区谷氨酰氨的含量失衡，说明在前庭代偿过程中氨基酸含量变化起着重要作用。

It is very peculiar that the region of arsenism and the number of arsenism people caused by burning high arsenic coals.

因此根据目前国内外对煤中砷的研究进展，在全国范围内有计划取样，研究中国煤中砷的含量、分布及其影响因素；探讨我国煤砷的赋存状态；选择大气中出现砷异常的西南地区，研究煤中砷脱洗机理；在室内模拟燃烧的基础上，研究燃煤砷排放机制。

Tasks are probably going to slow to atrickle at this point in time.But avoid your instinct to match that pace!The best way to counteract the leisurely pace of fate is to move quickly on your own feet,and see if the Gods can keep up.

近期你在做的一些工作的进展一点点的慢下来了，但是为了避免您在天性的驱使下不由自主的适应这样的节奏，最佳的方式就是你要和从容不迫的性格来做抗争，自己逐步的主动的去加快自己的步伐，神会保佑你的！

Last year, for example, we made major improvements in Azerbaijani, a language spoken by about 8 million people.

以去年为例，我们在阿塞拜疆语上取得了重大进展，而这种语言世界上仅有800万人在使用。

Research progresses have been performed during the past decade in the following aspects: ecologicaldatabase development, climate and its variability, ecophysiological response of plants to environments,vegetation and landscape changes, biodiversity patterns and their changes, plant functional types and traitswith relation to climatic gradient, productivity and carbon dynamics, pollen-vegetation relationship, tracegas emissions, land use and land cover changes, as well as biogeographical and biogeochemical modelling.

在过去的10年里，中国东北样带的研究进展表现在以下几个方面：生态数据库发展、气候及其变异性、植物对环境的生态生理响应、植被和景观变化、生物多样性格局及其变化、植物功能型和植物性状及气候梯度分析、生产力和碳动态、花粉-植被相互关系、痕量气体放散、土地利用和土地覆盖变化以及生物地理和生物地球化学模拟。

Important advance was made to Celastrus and ceangulin V after 20 years studies, but the target of Celangulin V was not verified and the metabolic dynamic of Celangulin V in organism was not touched because of the technique difficulty in testing and analysis of trace Celangulin V in organism. It will solve the difficulty that establishing the immunoassay of Celangulin V. The immunoassay of Celangulin V including the synthesis of artificial antigen, the preparation of antiserum, the immunoanalysis location of Celangulin V and the quantitative immunoassay of Celangulin V were studied systematicly in this paper.

苦皮藤素V是从卫矛科植物苦皮藤中分离出的一种具有杀虫活性的天然产物，可能作用于一类新的作用靶标。20多年对苦皮藤及苦皮藤素V的研究已取得了重要进展，但迄今还没有证实苦皮藤素V的作用靶标，对苦皮藤素V在生物体内的药代动力学研究也尚未涉及，这些方面的研究因为对痕量苦皮藤素V在生物体内分析、检测存在技术方法上的困难而受到限制，建立苦皮藤素V的免疫分析技术则可解决这些问题。

A 2-year-old male who had suffered from Hirschsprung's disease sine 2 months of age developed during 6 weeks bilateral fulminant exophthalmos with severe ecchymosis of eyelid and prominent congestion and chemosis of conjuntiva on the right eye and mild a degree on the left. A peripheral blood examination and liver function test showed mild abnormalities. A skull X-ray revealed increased bony density on the sphenoid ridge.

一位两岁男性病患，在2个月大时发现有Hirschsprung's disease，经过手术治疗，情形已改善，在2岁开始有右眼轻微凸出，经过6个星期，过程急速进展，演变成右眼严重凸出，眼睑严重瘀血，结膜充血水肿很厉害，角膜乾燥，左眼与右眼变化类似只是程度较轻微。

Now MSC become the chief seed-cell in cartilage tissue engineer, but the technology to stimulate MSC differentiate into chondroblast is not very successful,,the standard technology is culture the cell-ball in centrifuge tube,the reconstructured cartilage-like tissue is not achieve the mechanics of hyaline cartilage.

软骨组织工程的材料学研究主要体现在两类基质材料方面的进展，一类为天然基质材料，如胶原、壳聚糖、纤维素等；一类为人工合成可降解材料，如PGA、PLA等，但两者在来源、塑形能力及细胞识别信号等方面存在不足。
