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.

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.

Objective With the continuous improvement of treatment level and efficacy, the quality of life of patients with acute myeloid leukemia (AML) has attracted more and more extensive attention. This study aimed to explore the quality of life and related factors of patients with acute leukemia (AML) after chemotherapy. Methods The Chinese version of the quality of life scale for cancer patients(European Organization for Research and Treatment of Cancer, EORTC-QLQ-C30, and the general situation questionnaire were was used to investigate quality of life for 268 AML patients one year after treatment.And then the correlation between the EORTC-QLQ-C30 scores in various fields and the characteristics of patients were analyzed. Results There were statistical differences in the scores of age, AML types, work(yes or no),ECOG scores, and marital status in patients (P<0.05).The differences of PF, RF, EF, SF, QL, FI score of AL in different age groups were statistically significant (P<0.05), The PF, RF, EF, SF, QL and FI scores of AML patients in different age groups were statistical different (P<0.05).The scores of PF, RF, SF and QL in AML patients who returned to work were higher than those in AML patients who did not returned to work,while FA, DY and FI scores were the opposite(P<0.05).The PF, RF, SF and QL scores of married AML patients were higher than those of unmarried AML patients,while FA scores were the opposite(P<0.05).Age, classification, ECOG score, marital status were found to be associated with quality of life of AML patients by stepwise multiple regression analysis (P<0.05). Conclusion Old age, non-M3 type, high ECOG score, and unmarried are risk factors for poor quality of life for AML, which may serve as expected indicators for improving the quality of life of patients with acute leukemia.

Objective To analyze the expression of O6-methylguanine-DNA methyltransferase (MGMT) and DNA topoisomerase II (Topo II) genes in human brain gliomas and its influence on the chemosensitivity. Methods A total of 80 fresh human brain glioma specimens resected by craniotomy and 30 normal brain tissues resected by craniocerebral operation for traumatic brain injury or decompression for cerebral hemorrhage during the period from April 2012 to June 2017 were collected. The expression of MGMT and Topo II genes in the two kinds of specimens was detected by immunohistochemical method, and the influence on chemosensitivity was analyzed through brain glioma U251 and U87 cell culture, in vitro drug (temozolomide) intervention and Transwell invasion in vitro. Results There was a significant difference in the expression of MGMT and Topo II genes in glioma specimens and normal brain tissues (P<0.05). The positive expression rates of MGMT gene in the two kinds of specimens were 63.75% and 3.33% respectively while the positive expression rates of Topo II gene were 55.00% and 0.00%, respectively (P<0.05). Both of MGMT and Topo II genes were displayed in the nucleus as positive staining. There was no significant difference in transmembrane cell count of U251 and U87 cells between the experimental group given drug intervention in vitro and negative control group without drug intervention before the intervention (P>0.05). However, the transmembrane cell count of U251 and U87 cells in the experimental group after intervention was higher than that in the negative control group (P<0.05). After intervetion, U251 and U87 cells were with stronger invasiveness in the experimental group. Conclusion The positive expression rates of MGMT and Topo II genes are high in human brain glioma specimens. They may be involved in promoting glioma cell invasion, affecting tumor chemosensitivity.
