More than 10 years, I heard the company's customers valuable advice and technical absorption silk gun manufacturers, continue to improve, accumulated experience in various aspects, such as: absorption of silk Qiangtou, brothers and ceramic manufacturers have adopted easy Pengsui suction head, will not only affect production , Also increased equipment costs, we head into metal and greatly reduce the cost, a further absorption silk guns into the trachea and the row of silk from the centre, other manufacturers in 36 mm, and we changed to 38 mm, for users to replace the intake manifold, Pai more convenient when the silk, silk guns in the absorption of the two guns, made the point that hole, so it's suction row wire was also larger, users have won, we Asia and China over the years the company pursues " Is the quality of corporate life, the user is God, reasonable prices, better quality,"the purpose, we now more than 100 domestic and chemical fiber enterprises have long-term business, the company specializes in chemical fiber processing machinery parts.

十多年来，我公司听取了用户的宝贵意见，在吸丝枪制造技术上，不断改进，积累各方面经验，如：吸丝枪头子，兄弟厂家都采用陶瓷吸头容易碰碎，不但影响生产，还增加设备费用，我们改成金属头子，大大降低了成本，再有吸丝枪的进气管与排丝管中心距离，其他厂商于36mm，而我们改为38mm，为用户在更换进气管、排丝管时更为方便，在吸丝枪内的二级喷头中，孔的角度作了修正，所以它的吸力排丝量也较大，得到用户的好评，我们亚华公司多年来奉行"质量是企业生命，用户是上帝，价格合理，质量更优"的宗旨，目前我们与国内一百多家化纤企业有着长期业务往来，本公司专业加工化纤机械配件。

RESULT: In vitro, TISE at the concentrations of 760 and 380 mgL-1 had significant antagonistic effect on the normal bronchus slice contraction caused by histamine as well as on the sensitized bronchus slice contraction caused by egg albumin, but had no effect on the contraction caused by acetylcholine. in vivo, TISE at doses of 25 and 18 mgkg-1 could significantly prolong the latent period of expiratory dyspnea, tic and falling down caused by egg albumin in sensitized guinea pigs.

结果：离体实验，TISE 760，380 mgL-1对组胺致正常豚鼠气管片的收缩具有对抗作用，对卵白蛋白所致的致敏豚鼠支气管平滑肌收缩有极显著的抑制作用(P＜0.01)，而对乙酰胆碱所致气管片收缩无明显影响；整体实验，TISE 25，18 mgkg-1可显著延长卵白蛋白所致的致敏豚鼠呼吸困难、抽搐和跌倒的潜伏期(P＜0.01)。

The residual stress was remained in the excised porcine trachea and the membrane of the porcine trachea will disrupt as the endospore pressure increases.

Objective To explore the diagnostic value of transbronchial needle aspiration in the mediastinal lymphadenopathy and lung tumors.Methods TBNA and brushing biopsy were performed in 67 patients with mediastinal lymphadenopathy or with extrabronchial tumors,then the TBNA ang brushing biopsy were compared with the traditional ring clamp biopsy.

目的 探讨经气管镜行纵隔淋巴结及肺部肿瘤针吸活检联合刷检的诊断作用方法对经CT检查的67例纵隔淋巴结肿和叶、段支气管腔外占位的患者通过经气管镜行针吸活检和刷检并与传统的常规钳取活检对照。

PART FOUR EFFECTS OF MIL-4RA EXPRESSION VECTOR ON ASTHMATIC AIRWAY INFLAMMATION AND TH1/TH2 CELL DISFUNCTION THROUGH INTRAPERITONEAL ADMINISTRATION In the study of part three, we treated the mouse asthmatic model by intratracheal administration with mIL-4RA expression plasmid and observed obvious therapeutic effects. But intratracheal administration belongs to one of the insult therapies.

第四部分：腹腔注射mIL-4RA重组载体对哮喘小鼠气道炎症及Th失衡的干预作用前一部分研究中我们通过气道局部干预途径，即气管内直接滴注的方式，观察到mIL-4RA真核表达质粒对哮喘小鼠具有很好的治疗作用，但气管内滴注毕竟属有创性治疗，存在需要实验条件高，有较大的风险性，不易反复进行等缺点，这势必大大限制其在动物实验及进一步临床研究中的实际应用价值。
