Objective To build prenatal health education programs for primiparities and their spouses based on the concept of flipped classroom.Methods Expert questionnaires for prenatal health education programs for primiparities and their spouses based on the concept of flipped classroom were prepared by searching for original literatures from international and domestic databases. The Delphi method was used to investigate a total of 50 obstetrics experts from 18 ClassⅢ hospitals from Shandong province for two rounds. Results The concentration degree of these experts' opinions was high with an authority coefficient of 0.956 and a familiarity coefficient of 0.958, the determination coefficient was 0.954; the coordination coefficients for primary, secondary and tertiary indicators were 0.617, 0.423 and 0.391, respectively. The final health education program included 2 primary indicators, 11 secondary indicators and 55 tertiary indicators. Conclusions The experts' opinions on the prenatal education program for primiparities and their spouses are consistent. The program is highly scientific and reliable, which provides reference for prenatal health education for primiparities and their spouses based on flipped classroom.

Objective To investigate the effects of systematic desensitization therapy on the emotion of cancer patients with acute stress disorder. Methods A total of 50 cancer patients with acute stress disorder admitted in Cangzhou People's Hospital were selected and divided into control group (n=25) and observation group (n=25) according to the random number table from July 2016 to May 2017. Patients in the control group received conventional psychological nursing, while patients in the observation group received systematic desensitization therapy by professional psychological consultant on this basis. Hamilton Anxiety Scale (HAMA) and Hamilton Depression Scale (HAMD) were used to evaluate the anxiety and depression of the two groups. Results After two weeks' intervention, the anxiety and depression scores of the observation group were (15.00±1.12) and (14.36±1.38), respectively, which both were lower than those of the control group (t=5.099, 5.045; P＜ 0.05). Conclusions Systematic desensitization therapy is more favorable to alleviate negative emotions such as anxiety and depression in cancer patients with acute stress disorder than conventional psychological nursing, which has better intervention effects and is worth promoting in clinical work.

Objective To explore the mechanism of immediate effect regulated by acupuncture on acupoints in patients with migraine without aura(MwoA)during the interictal period.Methods A total of 28 MwoA patients were enrolled and resting-state functional magnetic resonance imaging(rs-fMRI)were performed at baseline and after acupuncture for 30 minutes.Paired t test was used to compare the differences of regional homogeneity(ReHo)and voxel-mirrored homotopic connectivity(VMHC)between two groups.Additionally,the correlation between the changes of rs-fMRI indexes and clinical scores was analyzed.Results In MwoA patients after acupuncture for 30 minutes,the mean regional homogeneity(mReHo)was decreased in the right lingual gyrus and right cere-bellum and was increased in the right middle frontal gyrus,while the z transformation voxel-mirrored homotopic connectivity(zVMHC)was significantly decreased in the bilateral cuneus compared with baseline.There was no significant correlation between imaging data and clinical scales.Conclusion Patients with MwoA after acupuncture for 30 minutes show abnormal ReHo and VMHC in multiple brain regions,which suggest that the mechanism of immediate effect may act through regulating pain-related brain regions.

OBJECTIVE: To investigate the effects of nicotinamide adenine dinucleoside phosphate oxidases 1(NOX1) and nuclear factor-kappa B(NF-κB) in tumor necrosis factor-α(TNF-α)-induced oxidative damage in A549 cells. METHODS: i) TNF-α was used to stimulated A549 cells at the concentrations of 0.0, 10.0, 25.0 and 50.0 μg/L. Cell inhibition rate in each group was tested by CCK-8 assay to select the appropriate concentration. ii) A549 cells in logarithmic growth phase were divided into blank control group, solvent control group, TNF-α group, diphenylene iodine(DPI) group and TNF-α+DPI group for NOX1 inhibitor experiment. Logarithmic growth phase A549 cells were divided into blank control group, TNF-α group, BAY11-7082 group and TNF-α+BAY11-7082 group for NF-κB inhibitor experiment. The relative expression of NOX1 and p65 protein in each group was detected by Western blot method. The relative expression of intracellular reactive oxygen species(ROS) were detected by flow cytometry. RESULTS: i) The inhibition rate of A549 cells increased with the increase of TNF-α dose(P<0.05), and 25.0 μg/L was selected as the stimulation dose of TNF-α in subsequent experiments. ii) The relative expression of NOX1, p65 protein and ROS in the TNF-α group was higher than that in the blank control group, solvent control group and DPI group, respectively(P<0.05). The above indexes in TNF-α+DPI group were lower than that in TNF-α group(P<0.05), but higher than that in DPI group(P<0.05). The relative expression of NOX1, p65 protein and ROS in the TNF-α group were higher than that in the blank control group and the BAY11-7082 group(P<0.05), while the above indicators in the TNF-α+BAY11-7082 group were lower than that in the TNF-α group(P<0.05). CONCLUSION: Inhibition of NOX1 or NF-κB can alleviate the oxidative damage induce by TNF-α in A549 cells.

ObjectiveTo investigate the abnormal changes of gray matter structure covariant network in post-stroke aphasia (PSA) patients. MethodsFrom June, 2019 to March, 2022, 15 PSA patients (patient group) from Dongzhimen Hospital, Beijing University of Chinese Medicine and Beijing Bo'ai Hospital were recruited, as well as 15 healthy subjects (control group). Their brain structure magnetic resonance imaging data were collected. The brain covariant network was constructed based on gray matter volume correlation, and graph theory analysis method was used to evaluate the global and node network level topology properties of structural covariant network. The differences of gray matter covariant network properties between patients and controls were compared. ResultsThere was no significant difference in the global network level topology properties between two groups (P > 0.05). At the nodal level, compared with the control group, the betweenness decreased in the right middle frontal gyrus, right posterior cingulate gyrus, right amygdala, left middle occipital gyrus, and increased in the right inferior frontal gyrus and the right suboccipital gyrus of the insula operculum (P < 0.05); the node degree decreased in the left superior frontal gyrus, left anterior cingulate and paracingulate gyrus, left hippocampus and left amygdala, while it increased in the right inferior frontal gyrus, left supplementary motor area, right superior occipital gyrus, right inferior occipital gyrus, and right lentiform pallidus (P < 0.05); the node efficiency decreased in the left anterior cingulate and paracingulate gyrus, left hippocampus, left amygdala, left temporal pole: superior temporal gyrus, and increased in the inferior frontal gyrus of right insula, left supplementary motor area and right suboccipital gyrus (P < 0.05). ConclusionThe abnormal reduction of node network properties in some brain regions in the left hemisphere of PSA patients may be a characteristic structural covariation pattern, and there may be some compensation in the right hemisphere of the structural network in some brain regions.
