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 observe the effect of pregabalin combined with mecobalamin on acute pain after lumbar surgery. Methods A total of 60 patients underwent single lumbar spine surgery in our hospital from January 2019 to December 2019. The incisions of patients were routinely infiltrated around the incision with 0.375% ropivacaine 20 mL. Patient-controlled intravenous analgesia (PCIA) was used. The patients were randomly divided into two groups. The experimental group: oral pregabalin 75mg bid and intravenous mecobalamin injection 0.5mg qd 1 day before surgery, five days in total. Control group: oral pregabalin 75mg bid and intravenous injection of equal volume of saline 1 day before surgery, five days in total. The VAS scores of preoperative and postoperative 6, 12, 24, and 48 h were observed. JOA scores were performed before surgery, 24 h after surgery, and 48 h after surgery. The doses of opioids, PCIA pressing times, remedial medications and adverse reactions were recorded at 24 h and 48 h after surgery. Results There was no significant difference in VAS scores between the two groups within 12 h after surgery, but the resting VAS and exercise VAS scores in the experimental group were lower than those in the control group during the period of 12～48 h (P<0.05). The amount of sufentanil, the pressing times of PCIA and the average remedial medication in the experimental group were lower than those in the control group at 24 h and 48 h after operation (P<0.05). There were no significant differences in JOA scores and adverse reactions between the two groups (P>0.05). Conclusion Pregabalin combined with mecobalamin in patients with lumbar spine surgery has good postoperative analgesia and low incidence of adverse drug reactions, but more randomized controlled trials are needed to confirm the safety and efficacy.
