The oversaturation of cholesterol in bile results in the formation of cholesterol stones. The liver is the organ which synthesizes cholesterol and secretes bile. Liver lipid metabolism research helps to explain the mechanism of cholelithiasis. Utilizing biochemical and biomolecular technology, we have done experimental work as follows: Analyse the ingredient changes of blood and bile samples from patients.

肝脏是合成胆固醇、分泌胆汁酸的器官，对肝脏胆固醇代谢的研究有助于阐明胆石症形成的原因，本文用生物化学和分子生物学的方法，分析了病人血液、胆汁中各种脂类成份的变化，以及肝脏胆固醇合成限速酶3-羟-3-甲戊二酸辅酶A还原酶（HMG-CoA Reductase）、胆汁酸合成限速酶7α-羟化酶（7α-hydrolase）的基因表达。

Liver pain, or even death in cirrhotic ascites; Paragonimiasis infected cysts, child or adult worms in human tissues and organs within the transitional, If staying in the lung, patients would cough, chest pain and other discomfort, live in the brain occur in epilepsy, hemiplegia, live mainly in the liver to the liver, liver pain, will live in the subcutaneous form transitional mass or nodule; Fasciolopsiasis worm infection can suffer from abdominal pain, diarrhea, malnutrition, etc.; Angiostrongylus cantonensis larvae in human migration, lesions in the brain, can cause severe headache, nausea, vomiting, fever and neck hard, there will be serious paralysis, lethargy, coma or even death.

感染食源性寄生虫病后可出现不同的症状或体征：华枝睾吸虫病的危害主要是肝受损，轻症者可出现胃肠道不适症状，重者常有肝肿大、肝区疼痛、肝硬变腹水甚至死亡；感染肺吸虫囊蚴后，童虫或成虫在人体组织与器官内移行，若寄居在肺里，患者会出现咳嗽、胸痛等不适感觉，寄居在脑中则出现癫痫、偏瘫等情况，寄居在肝内主要表现为肝大、肝痛，寄居在皮下则形成移行性包块或结节；感染姜片虫后可出现腹痛、腹泻、营养不良等；广州管圆线虫的幼虫在人体移行，病变集中在脑组织，可引起剧烈头痛、恶心、呕吐、发热及颈硬等，严重者会出现瘫痪、嗜睡、昏迷甚至死亡。

Tissue engineering is a multidisciplinary science merging with cell biology, material science, engineering and chemistry. Its basic idea is to expand a number of cells in vitro and seed them on a polysynthetic biodegradable polymer structure, and finally enable the organization of 3-dimmentional and functional tissues or organs.

组织工程技术是融合了细胞生物学、材料科学、工程学和化学的一门边缘学科，它的基本思想是用少量组织细胞经体外培养扩增后播种在可降解的生物支架材料上，再回植入体内形成有功能的组织或器官。

In the bolting time and blooming time, B deficiency mainly influenced on the growth of the propagative organ of rapeseed ( Brassica Napus L.), the agronomic character was similar to the seedlings, and the B concentration range of the rapeseed varieties which responded to the B scarce was 0.005 mg/L to 0.25 mg/L.

苔期和花期，缺硼主要影响甘蓝型油菜繁殖器官的形成和发育，营养生长农艺性状的变化规律与苗期相似，品种间对缺硼反应差异最大的硼浓度范围为0.005 mg／L—0.25 mg／L。

During the process of nuclear reprogramming, the zygotes of the normal embryos and the donor nuclei of thecloned embryos cease their unique repertoire of gene expression and reset their gene expression to the totipo-tent status, and then the normal and cloned embryos redifferentiate from the totipotent status to variousdifferentiated states for tissue generation or organogenesis.

通过细胞核重编程，首先，受精卵和克隆胚胎的供体核停止其特有的基因表达程序，恢复为全能状态的基因表达程序；然后，受精胚胎和克隆胚胎的细胞再从全能状态重新进入分化状态，最终形成各种组织和器官。
