ABSTRACT
Objective:To investigate the mediating effect of rumination in primiparae on the expectation gap of social support and postpartum depression, so as to provide a reference basis for early detection and intervention in the regulation of meternal postpartum depression.Methods:In this cross-sectional study, questionnaires were administered from November 2021 to March 2022 using the general information questionnaire, the Ruminant Thinking Response Scale, the Postpartum Social Support Scale, and the Edinburgh Postpartum Depression Scale to 266 primiparae at three tertiary level A hospitals, the First Affiliated Hospital of Xi′an Jiaotong University, the Second Affiliated Hospital of Xi′an Jiaotong University, and the Northwest Women′s and Children′s Hospital, for postpartum review, and the relationship between ruminant thinking, social support expectation gap, and postpartum depression was analyzed using correlation analysis, structural equation modeling, and application of Bootsrap method.Results:The social support expectation gap, ruminative thinking, and postpartum depression average scores were (16.74 ± 12.77), (39.43 ± 4.14), (6.77 ± 2.77) points, respectively.There were positive correlations between social support expectation gap and ruminative thinking, postpartum depression, and ruminative thinking and postpartum depression ( r=0.62, 0.75, 0.70, all P<0.01). Primiparae ruminative thinking partially mediated the relationship between social support expectation gap and postpartum depression, with the mediating effect accounting for 22% of the total effect. Conclusions:Social support expectation gap can directly affect the occurrence of postpartum depression, but also indirectly through ruminative thinking, and postpartum depression can be prevented and intervened from the perspective of reducing ruminative thinking in clinical practice.
ABSTRACT
Objective To compare the effects of closed reduction and interlocking intramedullary nail and percutaneous minimally invasive locking compression plate in treatment of tibial fractures.Methods 70 patients with tibial fractures were selected as research subjects,and they were randomly divided into the control group and the observation group according to the digital table,each group in 35cases.The control group was treated with closed reduction and interlocking intramedullary nail,while the observation group was treated with percutaneous minimally invasive locking compression plate.Then,the operation index,postoperative complications,treatment effect after treatment between two groups were compared.Results The operation time,fracture healing time,length of stay in the observation group were less than those in the control group[(70.37±11.06)min vs.(82.13±12.15)min,(3.02±0.61)month vs.(4.21±0.70)month,(13.39±3.02)d vs.(16.26±3.21)d](t=4.234,3.852,7.582,all P<0.05).The incidence rate of complication in the observation group was lower than that in the control group[14.28%(5/35) vs.51.42%(18/35)](χ2=10.943,P<0.05).The excellent rate in the observation group was statistically higher than that in the control group[94.28%(33/35) vs.74.28%(26/35)](χ2=5.285,P<0.05).Conclusion Closed reduction and interlocking intramedullary nail and minimally invasive percutaneous locking compression plate are successful in the treatment of tibial fracture,but interlocking intramedullary nail easily leads to delayed healing,complications and higher rate of surgery two times,while minimally invasive percutaneous locking compression plate can promote healing,curative effect is better.
ABSTRACT
Objective:To optimize the paper-roasted technology of Aucklandiae Radix. Methods:With methanol-water (65: 35) as the mobile phase, the contents of costunolide and dehydrocostuslactone were determined by HPLC. Senna was used to make diarrhea model in mice, and the sample decoction was administered for the mice by i. g at the dose of 10 g·kg-1 and the diarrhea index was de-termined. The paper-roasted technology of Aucklandiae Radix was optimized by L9 (34 ) orthogonal design taking the contents of cost-unolide and dehydrocostuslactone, and the diarrhea index in mice as the indices with the paper-roasted time, the paper-roasted temper-ature and the layer number as the influencing factors. Results:The variance analysis results show that the layer number and the paper-roasted temperature has the significant impact on the contents of costunolide and dehydrocostuslactone and the diarrhea index in mice. The best paper-roasted technology of Aucklandiae Radix was as follows:a layer of paper was covered by 4mm Aucklandiae Radix and repeated the same operation 5 times, and put them in drying baker at 120℃ for about 2 hours. After the essential oil of Aucklandi-ae Radix permeated on the paper with burnt flavor and dark brown in color, Aucklandiae Radix could be taken out. Conclusion:The optimum paper-roasted technology of Aucklandiae Radix is reasonable and feasible, which can provide reference for the establishment of the quality standard for paper-roasted Aucklandiae Radix pieces and the expanding of the clinical application.
