Objective To predict the active ingredients, targets and biological significance of Atractylodes macrocephala by network pharmacology, to explore the mechanism of its prevention and treatment of constipation, and to further verify its efficacy in combination with the clinical application of tutors. Methods The constituents of Atractylodes macrocephala were searched by TCMSP database and the compounds with bioavailability (OB) > 30% and drug-like property (DL) > 0.18 were screened, and the corresponding targets of each constituent were queried. Constipation-related target information was retrieved from two disease-related target databases of GeneCards and OMIM, mapping the two target genes to obtain intersecting targets, by visualization of query results with cytoscape 3.7.1. The resulting genes were queried by the interaction database (STRING) and the protein interaction (PPI) network was constructed. GO and KEGG enrichment analysis of key targets was carried out by R language in order to construct the network of “component-target-signal pathway”. Results Seven human target proteins and 2 859 constipation related human genes were obtained from Atractylodes macrocephala. It was found that the effect of prevention and treatment of constipation was mainly achieved by interfering with five genes of PGR, CHRM3, CHRM1, ACHE and CHRM2 and participating in six signaling pathways: cholinergic synapse, calcium signaling pathway, regulation of actin cytoskeleton, neuroactive ligand-receptor interaction, cAMP signaling pathway and PI3K-AKT signaling pathway. Conclusion The potential pharmacodynamic components, targets and signaling pathways of reuse Rhizoma atractylodis macrocephalae in the prevention and treatment of constipation can be predicted by network pharmacological method, which provides a theoretical basis for clinical application.

Objective To analyze the possibility of fusion function training to establish binocular tertiary vision function and consolidate the effect of postoperative strabismus correction in elderly people. Methods Conduct a retrospective study about 174 patients who were diagnosed with common strabismus and had corrective surgery at Guangzhou Aier Eye Hospital from October 2008 to December 2016, and those patients was performed after the fusion function training. According to the type of preoperative diagnosis of strabismus, they were divided into common esotropia group, common exotropia group, intermittent exotropia group. According to the difference of the best corrected visual acuity between the two eyes, they were divided into>2 lines group and ≤2 lines group. Monocular-suppression and cross-suppression patients firstly used de-inhibition training and then expand the fusion-range training. Patients with a smaller fusion range started training directly by expanding the fusion function. We compared and observed the fusion function and binocular condition between before and after strabismus surgery. Results The normal fusion range was established in 128 cases after strabismus correction, and there was no recurrence of strabismus and visual fatigue symptoms after 1 year of follow-up. Among them, the effective treatment rates of the common exotropia group, the common esotropia group, and the intermittent exotropia group after training are 32.35%, 28.57%, and 100%, respectively. The two groups which are divided into>2 lines group and ≤2 lines group are 11.54% and 100%, respectively. Conclusion Elderly patients with strabismus, especially those with intermittent exotropia or within two lines of best corrected visual acuity, have achieved good binocular vision after fusion training, have been improved visual fatigue, and the effect of strabismus surgery is consolidated.

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.
