Objective To evaluate the safety and efficacy of non-invasive ventilation with aerosolized surfactant (AS) in the treatment of premature infants with respiratory distress syndrome (RDS). Methods From July 2019 to June 2020, in this unblinded Phase I study, the premature infants with RDS who met the criteria with the informed consent of their guardians were enrolled. They were treated with nasal intermittent positive pressure ventilation (NIPPV) and received one dose (100 mg/kg) of aerosolized surfactant by vibrating mesh system (Aeroneb Solo) after hospitalization. The vital signs, adverse reactions and blood gas during areosolizing were recorded and prognosis of them also recorded in detail. Results Twenty infants were enrolled, nineteen completed the study, one died in 26 days. Five infants still required endotracheal intubation and mechanical ventilation after AS treatment. One hour after AS treatment, infants' oxygen saturation and indicators of pulse oximetry improved (P＜0.05), and heart rate decreased (P＜0.05) , but blood pressure and parameters of ventilator had no change (P＞0.05). Infants all tolerated the aerosol treatment well. No other significant adverse events were identified. Conclusion We have demonstrated the feasibility and safety of AS treatment in preterm infants with RDS receiving non-invasive respiratory support. The treatment was well tolerated by infants and clinical caregivers , but still need further study.

目的 系统评价胰岛素联用α-葡萄糖苷酶抑制剂(AGIs)治疗成人1型糖尿病(T1DM)的疗效和安全性。方法 检索中英文数据库,纳入关于胰岛素联用AGIs治疗成人T1DM患者的随机或非随机对照试验。使用Review Manager 5.3软件进行Meta分析。结果 共纳入10项研究,616例患者。与安慰剂或空白对照相比,在有效性方面,胰岛素联合AGIs可改善成人T1DM患者的糖化血红蛋白;降低平均血糖、空腹血糖和餐后2小时血糖;改善血糖波动情况,包括平均血糖波动幅度和最大血糖波动幅度(均P<0.05)。在安全性方面,AGIs增加总不良反应发生的风险(P<0.05),其中主要是胃肠道不适,但未增加低血糖的发生率和发生次数(均P>0.05)。胰岛素联合AGIs减少了每日胰岛素总剂量(P<0.05),但对体重、甘油三酯和高密度脂蛋白胆固醇无显著影响(均P>0.05)。结论 胰岛素联合AGIs可降低成人T1DM患者的糖化血红蛋白,改善血糖水平和血糖波动情况。AGIs不会增加低血糖的风险,但需重视其不良反应,特别是胃肠道不良反应。

Objective To systematically evaluate the efficacy and safety of adding alpha-glucosidase inhibitors (AGIs) to insulin therapy in adult patients with type 1 diabetes (T1DM). Methods Articles about randomized or non-randomized controlled trials of insulin combined with AGIs in adult patients with T1DM were retrieved from Chinese and English database. Meta-analyses were performed by using Review Manager 5.3. Results A total of 616 patients were included from 10 clinical trials. Compared with adding placebo or nothing, in terms of efficacy, the addition of AGIs resulted in decreased HbA1c, mean blood glucose, fasting plasma blood glucose and 2-hour postprandial blood glucose levels (all P<0.05). And this scheme improved the glucose variability including mean amplitude of glycemic excursions and the largest amplitude of glycemic excursions (P<0.05, respectively). As to safety, AGIs increased the risk of total adverse reactions (P<0.05), most of them were gastrointestinal complaints, while the occurrence and the frequency of hypoglycemia were similar (P>0.05, respectively). This scheme could also lead to the reduced total daily insulin dose (P<0.05) but had no significant effect on body weight, triglyceride or cholesterol concentration (P>0.05, respectively). Conclusions The addition of AGIs to insulin therapy in adult patients with T1DM may reduce HbA1c and improve the glucose levels and glucose variability. But total adverse effects especially the gastrointestinal complaints should also be considered in the use of AGIs although it does not increase the risk of hypoglycemia.

Objective Using the TCGA database to explore the prognostic effects of DNA methylation sites on lung adenocarcinoma. Methods TCGA database was used to collecting DNA methylation data, gene expression data and clinical data of lung adenocarcinoma patients. The population were divided into the exploratory group and the validation group. The LASSO regression analysis was used to screen the methylation sites associated with the prognosis of lung adenocarcinoma in the exploratory group. Receiver operating characteristic curve was used to evaluate the prediction effect of the model, and further verified in the validation population. Results A total of 158 methylation sites with differential expression and significant correlation with the mRNA expression of the corresponding gene were screened from the TCGA database. With LASSO regression analysis, the DNA methylation sites associated with prognosis of lung adenocarcinoma were cg19378330. Those patients with levels above the median methylation site were assigned to the high-risk group, while those with levels below the median methylation site were assigned to the low-risk group. Patients' death risk in the high-risk group were 38% higher than those in the low-risk group (OR=1.38, 95%CI=1.16-2.69). The area under the curve was 0.80 (95%CI=0.73-0.88) and the sensitivity was 86.2% in the exploratory stage population.Similar results were seen in the validation population. Conclusions The DNA methylation site cg19378330 was significantly associated withthe prognosisof lung adenocarcinoma, and could effectively predict the risk of lung adenocarcinoma.
