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.

Positive capital Questionnaire and pregnancy outcome were used to evaluate the effects of intervention.Results:The scores of pre-intervention, intervention for one month and post-intervention of PPQ was (123.87±18.86), (130.70±13.41) and (142.23±8.37) respectively. 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.

Objective To detect the expression difference of dynactin 2(DCTN2)and cell-cycle-related and expression-elevat-ed protein in tumor(CREPT)in gastric cancer and paracancer tissues,and to explore the relationship between DCTN2 and CREPT ex-pressions and the clinicopathological characteristics and prognosis of gastric cancer patients.Methods A total of 90 patients who received gastric cancer surgery from March 2014 to September 2015 in Affiliated Hospital of Xuzhou Medical University and were confirmed by his-tology were enrolled.The expression levels of DCTN2 and CREPT in gastric cancer tissues and paracancer tissues were detected by immu-nohistochemistry,and the Spearman correlation analysis was used to analyze the relationship between DCTN2 and CREPT in gastric cancer tissues;the relationship between their levels and clinicopathological characteristics were analyzed;Kaplan-Meier and Log-rank analysis were used to analyze the relationship between the expression levels of DCTN2 and CREPT and the overall survival time of gastric cancer patients;univariate and multivariate COX regression analysis were used to analyze the independent risk factors influencing prognosis of gastric cancer patients.Results The expression levels of DCTN2 and CREPT in gastric cancer tissues were significantly higher than that in paracancer tissues,and DCTN2 was positively correlated with CREPT in gastric cancer tissues(P<0.05).The expression levels of DCTN2 and CREPT were correlated with the tumor differentiation,TNM stage,invasion depth,lymph node metastasis(P<0.05),but were not significantly correlated with gender,age and distant metastasis(P>0.05);the results of prognosis analysis showed that the 1-year,3-year and 5-year cumulative survival rate and overall survival rate of gastric cancer patients in the DCTN2high-expression group were significantly lower than those in the DCTN2 low-expression group,and the 5-year cumulative survival rate and overall sur-vival rate of gastric cancer patients in the CREPT high-expression group were significantly lower than those in the CREPT low-expres-sion group(P<0.05).Univariate and multivariate COX regression analysis showed that both DCTN2 and CREPT were independent risk factors on the prognosis of gastric cancer patients.Conclusion DCTN2 and CREPT are highly expressed in gastric cancer tissues and their high expression were closely related to the poor prognosis of gastric cancer patients.DCTN2 and CREPT were expected to be potential markers and new therapeutic targets for gastric cancer diagnosis,and help to judge the prognosis of gastric cancer patients.

Objective To investigate the characteristics of muscle edema and fatty infiltration in thighs and relationship with clinical symptoms in Chinese patients with different phenotypes of dysferlinopathy.Methods A total of 32 patients were enrolled , including 13 limb-girdle muscular dystrophy 2B (LGMD2B), 13 Miyoshi myopathy (MM), 4 proximodistal myopathy and 2 hyper-creatine-kinase-emia.Clinical symptoms were evaluated using modified Gardner-Medwin and Walton ( GM-W) score.Muscle MRI was performed in thighs to observe fatty infiltration and edema.We then compared the age of onset , disease duration, GM-W score, muscle edema and muscle fatty infiltration between LGMD 2B and MM groups,and the relationship of muscle edema score and fatty infiltration score with disease duration and GM-W score in all patients.Results The median GM-W score was 4.00 (2.00,5.00) in all patients, 4.00 (3.00,4.50)in LGMD2B and 4.00(2.00,5.00)in MM, respectively.Muscle fatty infiltration appeared in 30 cases (93.75%), with the same pattern in LGMD2B and MM.The mean fatty infiltration score was 28.20 ±12.86 in all patients, 28.50 ±13.03 in LGMD2B and 29.00 ±12.63 in MM, respectively.Muscle edema appeared in 26 cases (81.25%) with same pattern in LGMB2B and MM.The mean edema score was 18.36 ±13.60 in all patients, 22.88 ±11.59 in LGMD2B and 16.77 ±13.80 in MM.The age of onset , disease duration, GM-W score, muscle fatty infiltration and edema score were not significantly different between LGMD2B and MM patients.Muscle fatty infiltration score significantly correlated with GM-W score (rs=0.737,P=0.000) and disease duration (rs=0.637,P=0.000).Conclusions Fatty infiltration and edema in thigh muscles are very common in patients with dysferlinopathy , with similar radiological changes in main subtypes.The muscle fatty infiltration can be used as a predictor of disease progression.

Objective To provide effective reference for quality analysis of the chemical composition and extraction of astragalus separation process by comparing the extract of astragalus and it’s IR spectra. Methods The saponins and flavonoids in astragalus were firstly extracted by the method of circumfluence with ethanol as solvent and the residue of ethanol-extraction was then used to extract polysaccharides by distilled water. Fourier transform infrared spectroscopy (IR) combined with second derivative infrared spectroscopy was applied to quickly identify astragalus herbs powder, water extraction of astragalus, astragalus alcohol extraction and water extraction of the residue of ethanol-extraction. Results The powder and 70% ethanol extract, 80% ethanol extract were around at 1 735 cm-1 (carbonyl stretching vibration absorption peak) has a weak, broad absorption, while the absorption peak was less obvious in boiling water extraction. So the maln components of astragalus water extraction are polysaccharides and also contaln a small amount of water-insoluble flavonoids. Alcohol extraction malnly contalns saponins and flavonoids, and flavonoid extract volume increases with increasing alcohol concentration in a certaln range.Conclusion This method can be a quick and easy identification for astragalus and it’s extraction for its chemical composition class, and provide the basis for further research quality.
