Objective To investigate the clinical efficacy of treating kidney deficiency-cold syndrome enuresis children with thunder-fire moxibustion. Methods 60 cases were randomly divided into a control group of 30 cases and a treatment group of 30 cases. Patients in the control group were treated with basic treatment (including adjusting diet, bladder function exercise, reflex training and so on); while patients in the treatment group were treated with thunder-fire moxibustion,three weeks for treatment. The research was aimed at assessing the clinical effect of the two groups,observing the number of enuresis days per week, the number of enuresis times per day,the sleep depth per day and the change of TCM symptom score, and recording the recurrence rate after 6 months of treatment. Results The clinical efficacy of treatment group was better than that of the control group,and the efficiency was 96.67%,which was higher than that of the control group 76.67%,and the TCM symptom score of the treatment group decreased than that of the control group, both of the differences were statistically significant (P< 0.05). The recurrence rates at 6 months after treatment was 10.34% respectively,which were lower than those in the control group(P＜0.05). Conclusion The therapy has good effect,it can reduce the number of enuresis times and has low recurrence.

Objective The effects of different inspiratory velocity PCV on respiratory function and inflammatory factors in patients with one-lung ventilation OLV were compared. Methods This was a prospective study of 75 patients with one-lung ventilation in 2018-2019. The subjects were randomized to the inspiratory velocity 30(group A),50(group B)or 70(group C)L/min after anesthesia and one-lung ventilation OLV. Respiratory mechanics,respiratory function,hemodynamics and blood gas parameters were compared between the three groups pre-OLV(T₀)and after 30 (T₁), 60 (T₂), and 120 (T₃)minutes of OLV.Center venous blood was collected to measure interleukin (IL)-6, IL-8,tumor necrosis factor (TNF)-α,andsoluble intercellular adhesion molecule-1 levels.Observation of pulmonary complications and occurrence of ARDS 3 days after operation were made. Results Hemodynamic and general patient status were similar between the three groups (all P>0.05). PaCO₂was lower in the group B and group C compared with the group A (P<0.05). Compared with T₀, PaO₂ and SVO₂were lower at T₁-T₃of the three groups(P<0.05). PH, SO2 and HB were similar between the three groups (all P>0.05).ΔVT was higher in the group B and group C compared with the group A (P<0.05);Ppeak were similar between the three groups (all P>0.05). PEEP was higher in the group B and group C compared with the group A (P<0.05); V_D/V_T decreased in the group B and group C compared with the group A (P<0.05).Compared with T₀,Qs/Qt increased at T₁-T₃ of the three groups (all P<0.05). Cdyn increased at T₁-T₃ of the group B and group C(all P<0.05). PaO₂/FiO₂ decreased at T₁-T₃ of the three groups(all P<0.05).Compared with T₀, the concentrations of Il-6, Il-8, TNF-α and sICAM-1 increased at T₁-T₃of three groups (P<0.05), and in group A and group B were lower than those in group C (P<0.05).The number of patients who had postoperative pulmonary complications PPCS or acute respiratory distress syndrome(ARDS)were similar between the three groups (all P>0.05). Conclusion In PCV mode, it can increase VT by increasing the inspiratory velocity, reduce the V_D/V_T, promote the exchange of CO₂, and increase the Cdyn, but it cannot improve the oxygenation and Qs/Qt.Inspiratory velocity of 50 mL/L to achieve the above improvement in respiratory function and respiratory mechanics in the case of a smaller inflammatory response. It may be recommended for use in patients undergoing OLV.

Objective To study the surgical effect of periodontal pulp combined therapy on severe periodontitis and the prognosis of surgery. Methods The study subjects selected 60 patients with severe periodontitis admitted to our hospital from December 2016 to March 2018 (60 teeth), and were randomly divided into observation group (30 cases) and control group (30 cases). The observation group received periodontal treatment with periodontal pulp and the control group received periodontal treatment alone. The total effective rate of treatment and the recurrence rate and the aesthetic satisfaction of the patients were compared between the two groups, and the clinical indicators before and after treatment were compared.

目的 采用生物信息学方法预测低氧预处理人胎盘绒毛膜间充质干细胞环状RNAs相对应的miRNA及其靶基因,并分析靶基因所参与的生物学过程和信号通路。方法 用Arraystar公司的商业软件为环状RNAs预测其相对应的miRNAs,分别用targetScan7.1和mirdbV5数据库预测miRNAs的靶基因,并取两个预测结果的合集,应用在线网站http://www.geneontology.org和http://www.genome.ad.jp/kegg对靶基因进行功能富集分析和信号通路富集分析。结果 功能富集分析表明,circRNAs的靶基因主要涉及到细胞发育、细胞分化和细胞发育调控。东京基因和基因组百科全书信号通路富集分析表明肿瘤中转录失控和有丝分裂原激活蛋白激酶(MAPK)信号通路最有意义,而且分析发现MAPK信号通路为核心通路。本研究表明,低氧预处理使得间充质干细胞中部分circRNAs的表达量发生差异性变化。结论 低氧预处理人胎盘绒毛膜间充质干细胞环状RNAs同低氧预处理间充质干细胞的生物学特性变化密切有关,为了解低氧预处理影响间充质干细胞特性发生变化的分子机制提供新思路。

Objective To predict the miRNA and its target genes of circular RNAs in hypoxia- preconditioned human palcenta chorionic mesenchymal stem cells using bioinformatics, and analyze the biological process and signaling pathway. Methods Arraystar's commercial software was used to predict the corresponding miRNAs of circular RNAs. The target genes of miRNAs were predicted by targetScan7.1 and mirdbV5 databases respectively, and an intersection of two prediction results was obtained. The online databases http://www. geneontology.org and http://www.genome.ad.jp/kegg performed functional enrichment analysis and signal pathway enrichment analysis of target genes. Results Functional enrichment analysis indicated that the target genes of circRNAs mainly involved cell development, cell differentiation and cell development regulation. The signal enrichment analysis of the Tokyo Gene and Genome Encyclopedia indicates that transcriptional misregulation in cancer and mitogen-activated protein kinase (MAPK) signaling pathway are most meaningful, and the MAPK signaling pathway is found to be the core pathway. This study showed that hypoxic preconditioning caused significant changes in the expression of mesenchymal stem cell circRNAs. Conclusion The changes of circular RNAs in hypoxia-preconditioned human placental chorionic mesenchymal stem cell is closely related to the biological characteristics of hypoxia-preconditioned mesenchymal stem cells. This study provides a new idea for understanding the molecular mechanism of hypoxic preconditioning affecting the changes of biological characteristics in mesenchymal stem cells.
