Results: Amang 128 patients, 56 cases were diagnosed as pulmonary carcinoma (43.75%), of which 30 cases were squamous carcinoma (53.57%), 22 cases were adenocarcinoma (39.29%), 4 cases were small cell undifferentiated carcinoma (7.14%); 37 cases were bronchial pneumonia (28.91%), in which 30 cases were given brush sampling, bacterial culture of BALF, the detectable rate of pathogenic bacteria were 50%(15 cases) and 40%(12eases) respectively; 12 eases were pulmonary tuberculosis (9.38%), of which 3 eases (25%) had concurrent endobronchial tuberculosis, smear of brush biopsy and BALF found Mycobacterium tuberculosis were 11 eases (91.67%) and 5 eases (41.67%) respectively, 2 eases were diagnosed as caseous tubereulous granuloma (16.67%); 2 eases were idiopathic pulmonary fibrosis (1.56%), lease was lymphoma of long.

结果：128例患者确诊为肺癌56例(43.75%)，其中鳞癌30例(53.57%)，腺癌22例(39.29%)，小细胞癌4例(7.14%)；支气管肺部炎症病变37例(28.91%)，其中30例经防污毛刷采样、支气管肺泡灌洗液行细菌学培养，病原菌的检出率分别为50%（15例）和40%（12例）；肺结核12例(9.38%)，其中合并支气管内膜结核3例(25%)，刷检涂片和支气管肺泡灌洗液找到结核杆菌分别为11例(91.67%)和5例(41.67%)，病理确诊为结核性乾酪样肉芽肿2例(16.67%)；特发性肺间质纤维化2例(1.56%)，肺淋巴瘤1例(0.78%)。

In order to study functions of glutathione S-transferase theta during preparation and synthesis of fibroin in Antheraea pernyi, expression of GSTT in silk glands of the fifth instar larvae was analyzed.

为明确柞蚕谷胱甘肽硫转移酶－theta在柞蚕丝素蛋白准备和合成过程中所起的作用，采用生物信息学的方法克隆了柞蚕GSTT基因，并分析其在5龄幼虫丝腺中的表达规律。

Methods The skeletal muscle stem cells were enzymatically isolated with collagen and dispase, and then purified by different adhesion time from 6 female SD rats. The purified cells were transinfected with adenovirus carrying lac-Z gene, and injected into the bladder neck of 6 autologous and 4 allogeneic rats. Tissues of blader neck and ureter were obtained in sacrified rats after 5 and 15 days, histological examination and X-gal staining were performed.

采用混合酶消化及反复差速贴壁法分离、纯化培养SD大鼠骨骼肌干细胞，然后用携带lac-Z基因的腺病毒载体转染肌干细胞，待转染成功后将携带lac-Z基因的骨骼肌干细胞注射于自体和同种异体的膀胱颈及后尿道周围，分别于注射后5、15d，处死大鼠取出膀胱颈及后尿道，行组织学检查及X-gal染色。

Results The cases of this study account for 5.2%(184/3534) of primary bronchiogenic carcinomas and 14.5%(184/1265) of pulmonary adenocarcinomas that were admitted by PUMCH during the same period. The ratio of males to females is 1:1.24. 27.2% of the cases were discovered during health checkups, with no obvious symptoms. Because of its radiological features, BAC could easily be misdiagnosed as pneumonia, pulmonary tuberculosis or interstitial lung disease, and the ratio of the misdiagnosed cases is as high as 41.9%.

结果 本组病例占我院同期原发性支气管肺癌的 5.2 （ 184/3534 ），占我院同期肺腺癌的 14.5%（ 184/1265 ），男女之比 1：1.2 ，无症状体检发现者占 27.2%， BAC 影像学的表现易被误诊为肺炎、肺结核、间质性肺病，误诊比例高达 41.9%，综合治疗的疗效较单一治疗效果好。

Coexistent malignancy was found in 12.3% of polyps. 132 patients had follow-up of more than 6 months.

切除的息肉组织学均为腺瘤，同时伴有恶变的占12.3%。132例患者随访在6个月以上。

Adenocarcinoma had a solid trabecular, papillary, cribriform or diffuse pattern. The cribriform-morular and papillary cells were positive for CEA and EMA, but focally positive for AFP by immumohistochemical analysis.

腺癌组织学表现为实体巢状或弥散分布，以及肿瘤性的乳头状上皮、筛状结构，免疫组织化学染色CEA、EMA阳性，而AFP灶性阳性。

Benign SO showed itself to be solid,cystiform or cystiform-solid.They were typically filled with gelatinoid and light green-yellow fluid.

其中，7例良性，大体呈囊性、实性、囊实性，囊内为黄褐色胶样物和淡黄绿色液体；组织学类型有单纯型、腺瘤型、囊性变型。
