Laryngopharyngeal secretions of neonates labored by 90 cases of the puerpera and pregnant women of UU posi tivene ss were detected for UU.

采用分离培养法对605例孕产妇的宫颈分泌物进行UU检测，并对其中90 例UU阳性的孕产妇分娩新生儿喉咽部分泌物进行UU检验。

Result The flexibility of the scaffold material was powerful. The load-elongation curve of the mechanical testing was similar to that of ACL, the maximum load, the ultimate stress and the Young's modulus of the scaffold materials were 52.61 N, 14.96 MPa and 202.08 MPa respectively. Human ACL cells displayed the representative characteristercs of the ligamentous fibroblasts, and synthesized extracellular matrix, such as type Ⅰand Ⅲ collagen protein. The scaffold materials had no cytotoxicity. Human ACL cells adhered, grew and proliferated well both on the surface and in the holes of the scaffold materials.

结果］韧带支架材料的柔韧性强，拉力测试的负荷－拉伸曲线与韧带的拉伸曲线相似，其最大负荷、极限应力和弹性模量分别为52.61N、14.96MPa和202.08MPa；体外分离培养的人前交叉韧带细胞呈典型的成纤维细胞特征，能在体外分泌Ⅰ、Ⅲ型胶原等细胞外基质；支架材料无细胞毒性，人前交叉韧带细胞可在支架材料上黏附、生长并分泌细胞外基质。

Therefore, the LsHNXs genes were cloned in this study, and their function was studied by RNAi. The main results were shown as follows:1 The conservative sequences of three LsHNXs genes (LsHNX1, LsHNX2, and LsHNX3), and the 3'-terminal specific sequences of LsHNX2 and LsHNX3, were cloned by RT-PCR and 3'-RACE.2 The plant RNAi vectors were constructed and the transformation of Limonium sinense was done. The RNAi lines of three single-genes and one double-gene were obtained and were propogated rapidly for the molecular and the stress tolerance analysis.3 To be compared with wild type, the Na+ and K+ contents secreted by the leaves of LsNHX1 transgenic plants were remarkably higher.

主要实验结果如下：1采用RT-PCR和3'-RACE方法从补血草中克隆获得LsNHXs基因家族三个成员LsNHX1、LsNHX2和LsNHX3的保守区序列以及LsNHX2和LsNHX3的3'端特异序列。2构建植物基因RNAi沉默表达载体并转化补血草，获得三个单基因和一个双基因的RNAi沉默表达植株，快繁转基因植株供分子鉴定和耐逆分析。3LsNHX1转基因植株叶片表面分泌物中的Na+、K+离子含量比野生型对照显著增加；叶组织内Na+离子含量和K+离子含量均略高，但差异不显著；K+/Na+比没有显著差异。4LsNHX2转基因植株叶片表面分泌物中的Na+离子含量比野生型对照有所下降，但差异不显著；K+离子含量比对照显著降低。

Signal peptide sequence was removed lest it couldnt be recognized by Bacillus subtilis, gene coding for mature peptide was ligated to downstream of sacB signal peptide sequence of pWB980 to form a new ORF and generate pWB980-LipA, gene coding for its chaperone was also amplified and ligated to the downstream of LipA to generate a secretion/expression vector pWB980-LipAB.thechaperone gene was sequenced and analyzed by multiple alignments, resulted showed that there were mutations of nucleotides(1～7) and amino acids (1～2) with the other reported genes.

为了防止枯草芽孢杆菌信号肽酶不能识别脂肪酶的信号肽，切除掉脂肪酶的信号肽编码序列，与枯草芽孢杆菌分泌表达质粒pWB980连接并与质粒上的SacB信号肽构成一个完整的开放式阅读框，获得重组质粒pWB980-LipA，因为该脂肪酶的活性表达需要一个特异性分子伴侣帮助折叠成有活性的构象，将脂肪酶分子伴侣基因串连到脂肪酶基因的下游，获得重组分泌表达载体pWB980-LipAB并且测序分析分子伴侣的基因序列和氨基酸序列并与其它报导的序列进行了比对，发现有1到7个碱基的差异和1到2个氨基酸残基的突变。

Methods 152 patients with PPROM were divided into normal vaginal secretion group and abnormal vaginal secretion group, and the result of vaginal secretions, the prognosis of maternality and perinatal fetus.

将152例未足月胎膜早破患者分为阴道分泌物正常组和异常组，分析比较阴道分泌物检测结果及产妇、围产儿的预后情况。

Maxillary sinus puncture was performed on these patients both for sampling of sinus contents and irrigation of the diseased sinuses. Aspirate contents of the sinuses were collected for aerobic and anaerobic cultivation. 3 A prospective study of pediatric patients with community-acquired rhinosinusitis was conducted. Bacterial culture was performed on the specimens obtained from maxillary sinus by puncture and middle meatus by endoscopic sampling. The correlation and diagnostic usefulness of endoscopic middle meatal culture versus maxillary sinus puncture were determined.

我们搜集鼻咽癌放射线治疗后患有急性上颔窦炎的病人，以上颔窦穿刺搜集这些病患的鼻窦分泌物并冲洗其患病的鼻窦，收集到的鼻窦分泌物则送往实验室做细菌培养。3 我们执行前瞻性研究，收集患有社区感染鼻及鼻窦炎的儿童，这些病童会同时接受内视镜中鼻道培养与上颌窦穿刺培养，为了厘清儿童使用内视镜中鼻道培养的可信度，我们计算内视镜中鼻道培养与上颌窦穿刺培养结果的关联性与诊断测试。

Clinical symptoms appear mild because of part of secretion of thyroid hormone,but followed by other signs of pituitary hormone deficiency ,for example ,hypoglycemia,micropenis diabetics insipidus.

TSH和TRH分泌不足的患儿常保留部分甲状腺激素分泌功能，因此临床症状较轻，但常有其他其他多种垂体激素缺乏的症状如低血糖小阴茎或尿崩症等。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。
