Objective:To explore the effect of positive psychological intervention based on PERMA model on the fear of cancer recurrence and psychological capital in breast cancer patients during chemotherapy.Methods:A total of 60 breast cancer patients who received chemotherapy from November 2019 to January 2020 were divided into intervention group and control group with 30 cases in each group. The control group received routine health education. On this basis, the intervention group was given 8 times of positive psychological intervention. The general situation questionnaire, Fear of Progression Questionnaire-Short Form (FoP-Q-SF) and Positive Psychological Capital Questionnaire (PPQ) were used to evaluate the results of the two groups before and after intervention.Results:Before, 4 weeks after and 8 weeks after the intervention, the score of fear of cancer recurrence in the intervention group were 39.67±4.24, 34.60±3.78 and 31.17±3.60. The difference of the score of fear of cancer recurrence at different time points was statistically significant ( F value was 257.757, P<0.05). The scores of psychological capital were 113.20±19.75, 125.57±18.79 and 134.43±17.59. The difference of psychological capital level at different time points was statistically significant ( F value was 154.225, P<0.05). Conclusions:Positive psychological intervention based on PERMA model can reduce the fear of cancer recurrence in breast cancer patients during chemotherapy and improve their psychological capital level.

Objective To investigate cognitive function and behavior characteristics in the childhood onset schizo?phrenia patients with or without obsessive-compulsive symptoms. Methods One hundred forty-nine schizophrenia chil?dren were recruited and 72 healthy children served as children control group. According to the Schedule for Affective Dis?orders and Schizophrenia for School-Age Children-Present and Lifetime Version (K-SADS-PL), the patients were fur?ther divided into two groups, the children with obsessive-compulsive disorder group (70 cases) and the children without obsessive-compulsive disorder group (79 cases). All the children were retrospectively surveyed and the Achenbach’s Child Behavior Check-list (CBCL) was used to assess their social competence and behavioral characteristics at the age from 6-year-old to 10-year-old. The cognitive function was estimated with WISC, STROOP color and word test, trail making test, visal spatial memory test and maze test. Results Compare to the control group, the CBCL factor scores of behavior problems were higher (P<0.01), social ability factor scores were lower (P<0.05) and all factor scores in the cog?nitive function tests were lower (P<0.05) in the two patients groups. Compare to the patients without obsessive-compul?sive symptoms, the CBCL factor scores of the school situation (P<0.01), splitting force (P<0.01), and physical complaints (P<0.01) were significantly higher and the scores were significantly lower in the test of common sense (P<0.01), wood (P<0.01), STROOP (P<0.01) and BVMT-R (P<0.01) in those with obsessive-compulsive symptoms. Correlation analysis showed that social competence total scores were positively correlated with similarity in the patients with obsessive-com?pulsive symptoms (r=0.31, P<0.01);while behavior problems total scores were negatively correlated with wood (r=-0.31, P<0.01) and patchwork (r=-0.32, P<0.01) in the patients without obsessive-compulsive symptoms. Conclusion The schizophrenia children with obsessive-compulsive symptoms have more behavioral problems in pre-symptom period and their cognitive dysfunction are more severe following onset of the disease. Cognitive function is related to behavioral prob?lems and social competence in the schizophrenia children with or without obsessive-compulsive symptoms .

AIM: Studying the mechanism of protective role of metallothionein (MT) in hypoxic preconditioning(HPC) of cultivated rat cardiomyocytes. METHODS: Using the model of hypoxia/reoxygenation of cultivated rat cardiomyocytes. Determing the contents of MT, malonyldialdehyde (MDA) - metabolism product of lipid peroxidation and the activities of Na+ - K+ ATPase, Ca2+ - Mg2+ ATPase of cardiomyocytes 24 h after HPC, the determining the relevant changes after using MT antibody. RESULTS: After 24 h in HPC, the contents of MT and activities of Na+ - K+ ATPase, Ca2+ - Mg2+ ATPase were obviously higher than those in the control and hypoxia/reoxygenation(P＜ 0. 05 ), and the contents of MDA were decreased remarkedly (P ＜ 0.01 ). Then after using MT antibody, the activities of two enzyme were progressively decreased and the contents of MDA were significanily higher than those in the control and MT antibody - free groups(P ＜ 0.01 ). CONCLUSION: HPC may induce excessive synthesis of MT, and MT can protect myocardial reoxygenation injury by eliminating lipid peroxidation and rising the activities of Na+ - K+ ATPase and Ca2+ - Mg2+ ATPase.

Higher level of natural childbirth rate([86.7%] versus [63.3%]; χ2=4.356; P=0.037<0.05) and lower rate of perineal injury([16.7%] versus [43.3%]; χ2=5.079; P=0.024<0.05). The rate of exclusive breastfeeding during hospitalization ([90.0%] versus [66.7%]; χ2=4.812; P=0.028<0.05) after intervention as compared with those who received routine care. Conclusion:Group prenatal care intervention model can improve the level of positive psychological capital and pregnancy outcome.

BACKGROUND:Large numbers of experimental data have confirmed that bone marrow mesenchymal stem cel s have a positive therapeutic effect on cerebral ischemia-reperfusion injury, but there are few reports about intravenous administration of bone marrow mesenchymal stem cel conditioned medium in the treatment of stroke.
OBJECTIVE:To investigate the effects of the conditioned medium of rat bone marrow mesenchymal stem cel s on the recovery of neurological function in rats after cerebral ischemia-reperfusion injury.
METHODS:The bone marrow mesenchymal stem cel s were isolated from rat bone marrow. When cel s at passage 2 or 3 reached 90%confluence, the original culture medium was removed. Then the cel s were cultured in serum-free DMEM for 18 hours. After that, the culture solution was col ected as the conditioned medium of rat bone marrow mesenchymal stem cel s. Adult rats were subjected to 2 hours of right middle cerebral artery occlusion. Ischemia-reperfusion injury rats were randomly assigned to three groups:control group, simple culture medium group and conditioned medium group, and respectively given injection of normal saline, DMEM, conditioned medium (10 mL/kg) via the tail vein at 2, 24, 48 hours after operation.
RESULTS AND CONCLUSION:There was no difference in the behavioral tests among the three groups at postoperative 2 hours (P>0.05). Compared with the control and simple culture medium group, neurological impairment was significantly improved in the conditioned medium group at postoperative 1, 3, 5 days (P<0.05), but there was no significant difference between the control and simple culture medium groups. At postoperative 5 days, brain edema was significantly eased in the conditioned medium group in comparison to the control and simple culture medium groups (P<0.05), and there was also no difference between the latter two groups (P>0.05). These results suggest that rat bone marrow mesenchymal stem cel s-conditioned medium via intravenous administration can significantly ease brain edema and improve the neurologic function after cerebral ischemia-reperfusion injury.

Objective:To investigate the effect of low expression of human epidermal growth factor-like domain protein 7 (EGFL7) gene in cervical cancer cell Hela on its migration and invasion ability.Methods:Cells in the experimental group used small interfering RNA (siRNA) to target the human EGFL7 gene to reduce the expression of EGFL7 in human cervical cancer cells Hela, and cells in the control group were transfected with Mock-siRNA. Real-time quantitative PCR was used to detect the EGFL7 mRNA content of cancer cells in each group; Western blot was used to detect EGFL7 protein expression of cancer cells in each group; The cell scratch healing experiment and Transwell experiment were used to detect the migration and invasion ability of Hela cells in each group.Results:siRNA reduced the protein expression of EGFL7 in human cervical cancer cell Hela. The wound closure percentage of Hela cells in the control group was 74.1%±6.8%. After the expression of EGFL7 was reduced, the percentage of cervical cancer cells was 42%±4.9%, and the wound closure ability was significantly reduced ( P<0.05) . The results of Transwell cell transfer showed that the number of cells successfully transferred by Hela cells in the control group was 179.24±20.01, while the number of cells successfully transferred by Hela cells with low EGFL7 expression was 79.22±13.16. The transfer ability of cells transfected with EGFL7-siRNA was significantly reduced ( P<0.05) . The results of invasion experiments showed that the number of successfully transferred cells in the control group was 79.35±8.04, the number of cells successfully transferred in the EGFL7-siRNA group was 26.98±6.24, and the invasion ability of Hela cells with low expression of EGFL7 decreased ( P< 0.05) . The expression of E-cad in Hela cells with low expression of EGFL7 was up-regulated, and the expression of MMP2/9 protein was down-regulated (all P<0.05) . Conclusion:The low expression of EGFL7 can reduce the migration and invasion ability of cervical cancer cell Hela through the EMT pathway.
