We Investigated the species of diseases and insect pests, species of natural enemies, distribution and dominant species in export vegetable bases in Shandong Province. Dynamics of main diseases and insect pests were studied.2. We investigated the main control technologies for diseases and insect pests, types and application methods of pesticides.3. Effects of crop varieties, fertilities and cultivation on diseases and insect pests, production and pesticide residues were examined.4. Control effects and application technologies of frequency trembler grid lamps, greenhouse ozone machine and insect-proof net were tested.5. By research, seven biological preparations and twelve chemical pesticides with high activity, low toxicity and low residue were screened.

主要结果如下：1查清了山东省出口蔬菜基地蔬菜病虫害发生种类，天敌种类、分布、并评价上风种；探明了主要病虫发生消长规律。2查清了山东省出口蔬菜基地目前病虫害防治的主要应用技术、施药种类及主要施药方式。3明确了作物品种、肥力、栽培方式等农业措施对病虫发生、产量和农残的影响。4明确了频振式杀虫灯、温室病害臭氧防治机、防虫网等物理措施防治效果及其应用技术。5通过实验，筛选出7种生物制剂和12种安全有效低毒低残留化学农药品种。

Objective To study the necessity of the screening and confirmation of Treponema pallidum infection by three serologic tests.

Genetic diversity among 7 populations of Trillium tschonoskii were analyzed by using inter SSR and amplified fragment length polymorphism molecular markers. The results were as follows:(1)ISSR: 12 out of the 100 primers showed consistent banding patterns and amplification, a total of 135 bands were produced with an arrange of 250-2500bp, 46 of which (34.07%) were polymorphic.

应用锚定SSR和限制性片段多态对7个延龄草居群的遗传多样性进行了分析，结果如下：从100个引物中筛选出12个ISSR引物，在250-2500bp之间共扩增出的135个条带，其中多态性带为46，占34.07％。

Micrognathia also was more common defects in trisomy 18. The vast majority of fetus with trisomy 13 and 18 can be detected by routine ultrasound examination.

小下颌、叠指畸形也是较常见的畸形，见于18三体。18三体和13三体的畸形在超声筛查中检出率较高。

The positive rate of true inborn metabolic error was 0.99％(2/2100), and the false positive rate 1.28％(29/2100) in this study.

在本研究中，先天性代谢异常的发生率为0.09％(2/2100)，筛检中伪阳性的比率为1.28％(29/2100)。

Pneumatization and proliferation of middle turbinate and bent uncinate process were the most common anatomic variation in the diseased group.

病变侧上颌窦口周围的中鼻甲气化、增生及钩突偏曲、筛泡骨性增生等解剖结构异常的发生率明显高于对照侧

Finally, the integrity of clinical trials is undermined by the lack of an accurate screen, Dr.

最后，由于缺乏准确的筛查试验，该临床试验的完善性受到限制。
