Methods Sixty-seven eyes of 50 patients with dry eye received a silicone punctum plug as treatment. Of the 50 patients, there were 17 males and 33 females, and the average age was 37 years. All patients were followed up for three months. A Schirmer Ⅰ test and break-up time were used as measurements before treatment and one and three months after treatment. These measurements were used to evaluate the efficacy of using this treatment for dry eye.

确诊为干眼症的患者50例67眼，均予以泪小点塞治疗，其中接受单眼治疗患者33例，双眼治疗患者17例，按常规记录治疗前、治疗后1个月和3个月的基础泪液分泌量和泪膜破裂时间，检查的结果按两种方法分组进行统计分析，Ⅰ组45例60眼进行治疗前后自身对照，Ⅱ组30例单眼治疗患者左右眼同期对照。

Compared to the control, the increment in membrane permeability, MDA and Pro contents were smaller, and the reducement in activities of SOD and POD, contents in soluble protein, dry weight of aboveground, dry weight of underground, plant height and stem diameter were smaller in leaves of pepper under low temperature and poor light stress with PEG seed-soaking. These results suggested that PEG seed-soaking could increase the resistance ability to low temperature and poor light stress of pepper seedlings.

PEG浸种处理可使辣椒幼苗地上部干质量、地下部干质量、株高、茎粗和叶片SOD、POD活性、可溶性蛋白含量的下降幅度均较低温弱光对照显著减缓，细胞膜透性、MDA与Pro含量的增加幅度均较低温弱光对照显著降低，表明PEG浸种处理能够提高辣椒幼苗对低温弱光的适应能力。

Transcriptional activity of ACL recombinants normalized by Renilla was significant difference with pGL3-Basic expect for construct -27 and -15 (P＜0.01). Construct -919 contains highest activity. 3 times reduction of transcriptional activity from-919 to -679bp indicated that negative regulation factors located probably in this region. The activity started on construct -73 suggested the basal promoter activity was located within the -73 to +77bp region; Transcriptional activity of IDHβrecombinants was not significantly different between the recombinant -58 and pGL3-Basic. The activity started on construct -82, decreasing with the length of the fragment up to -164 in despite of a bit of fluctuation, and kept increasing from construct -164 up to -279. Thus, the basal promoter activity was located within the -82 to +16bp region, whereas the upstream 197bp conferred maximal transcriptional activity.

采用5'端缺失策略，结合启动子预测结果，分别构建了8个ACL基因和19个IDH3β基因启动子区重组子，将其转染猪PK15细胞系，并利用荧光素酶双报告基因系统检测了它们的活性，结果表明：在所构建的猪ACL基因5侧翼序列的8个重组子中，除pGL-ACL27和pGL-ACL15外，其它重组子的荧光素酶活性与阴性对照均达到极显著水平(P＜0.01)，表明它们均具有启动子活性，pGL-ACL919活性最强，到pGL-ACL679活性下降了将近3倍，说明从-919bp到-679bp区域可能存在负的调控位点，从pGL-ACL621到pGL-ACL73活性有小幅度下降，到pGL-ACL27活性降到与阴性对照水平无显著差异，表明维持该启动子的基本活性区域位于-73bp到+77bp之间；IDH3β基因启动子活性开始于pGL-IB82，然后虽然有些波动，但是活性一直下降直到-164bp处，之后活性又开始升高，直到-279bp处活性达到最高，这些表明维持该启动子的基本活性区域位于-82bp到+16bp之间，从-82到-279之间的179bp区域具有最高的启动子活性。
