Objective To evaluate the protective effect of radiation protection safety education (RPSE) on patients with differentiated thyroid carcinoma (DTC) undergoing iodine-131 (¹³¹I) treatment. Methods The DTC patients who undergo ¹³¹I treatment were divided into the control group and the RPSE group using the convenience sampling method, with 142 patients in each group. Patients in the control group received routine health education, while the RPSE group received routine health education combined with RPSE. Dose equivalent rate (DER) on pillows, bed sheets, quilt covers, and household waste of patients were compared between the two groups upon discharge. Results The median (M) DERs of patients' pillows, bed sheets, quilt covers and household waste were 3.86, 3.63, 3.91 and 56.59 times higher in the control group compared with the environmental background level, respectively. The M DERs of patients' pillows, bed sheets, quilt covers were 2.23, 2.18, and 2.55 times higher in the RPSE group compared with the environmental background level, while the M DER of household waste was equivalent to the environmental background level. The DERs of patients' pillows, bed sheets, quilt covers, and household waste in the RPSE group were significantly lower than those in the control group (all P<0.001). The DERs of the above four items were lower in both male and female patients in RPSE group compared with same-gender patients in the control group (all P<0.001). The patients' DERs of the above indicators had no significant difference among different gender in both control group and RPSE group (all P>0.05), except for higher DER of household waste in female patients than that of male patients in the control group (P<0.05). There were no significant differences in the DERs of pillows, bed sheets, quilt covers, and household waste across subgroups, where patients received different treatment doses, of both the control group and the RPSE group (all P>0.05). Conclusion RPSE for DTC patients treated with ¹³¹I, reduces the DERs of pillows, bed sheets, quilt covers, and particularly household waste.

Objective:To systematically evaluate the effect of couple-centered psychological intervention on breast cancer patients.Methods:Randomized controlled trials published in PubMed, Embase, Web of Science, Scopus, CINAHL, Cochrane Library, JBI, CNKI, Wanfang, Vip and CBM database on the effect of psychological intervention on breast cancer patients with husband and wife as the center were searched by computer. The retrieval time was from the establishment of the database to September 2020. Two reviewer independently conducted literature screening, data extraction and literature quality evaluation according to the inclusion and exclusion criteria, and Meta analysis was carried out using RevMan 5.3 software.Results:A total of 879 patients were included in 11 articles. Meta analysis results showed that the couple-centered psychological intervention not only improved the quality of life, but also improved the anxiety of breast cancer patients ( SMD=1.54, 95% CI 0.22-2.86, P=0.02) and depression ( SMD=1.22, 95% CI 0.12-2.33, P=0.03). Conclusions:After psychological intervention, the anxiety and depression of breast cancer patients were improved and the quality of life was also improved. Due to the inconsistency in the mode, frequency and evaluation index of psychological intervention, more large samples and high-quality studies are needed to further verify the effect of couple-centered psychological intervention on breast cancer patients and spouses centered on husband and wife.

Objective To evaluate the significance of kidney depth obtained by computed tomography (CT) in measuring glomerular filtration rate (GFR) by Gates method in living kidney transplant donors.Methods Individual kidney depth was compared among the estimates of Tφnnesen,Taylor and Li Qian formulas and CT measurements in 167 living-related kidney transplant donors respectively.While maintaining the active region of interest of kidney and background unchanged in 137 99mTe-DTPA renal dynamic imaging cases,GFR was measured by Gates' method and individual kidney compared among the estimates of Tφnnesen,Taylor and Li Qian formulas and CT measurements.Results Left/right kidney depth obtained by CT,Tφnnesen,Taylor and Li Qian formula was 6.82 ± 0.96/7.02 ± 1.00,5.67 ± 0.58/5.71 ± 0.59,6.43 ± 0.77/6.81 ± 0.72 and 7.03 ± 0.76/7.06 ± 0.70 cm;GFR 45.44 ± 9.04/46.61 ± 9.06,37.54 ± 6.34/37.37 ± 6.02,43.39 ± 7.59/44.62 ± 6.94 and 46.99 ± 8.04/46.70 ± 7.30 ml/min respectively.Individual kidney depth and GFR calculated by Taylor and Li Qian were higher than those of Tφnnesen formula (P＜0.01).Individual kidney depth and GFR calculated by CT were higher than those of Tφnnesen and Taylor formulas (P＜0.01).Left kidney depth and GFR calculated by Li Qian formula were higher than those of CT measurements (P＜0.01).And no significant difference existed in right kidney(P＞0.05).Conclusions Kidney depth measured by CT improves the accuracy of kidney depth estimated by Gates method and optimizes GFR in living donors for renal transplant.

Objective To get further insight into the breakthrough pain experiences in advanced cancer patients in order to provide targeted nursing measures for breakthrough pain patients. Methods Semi structured interviews were performed in 12 advanced cancer patients. Colaizzi analysis program was used to analyze, induct and extract the themes. Results The breakthrough pain experiences of advanced cancer patients were as follows:overall perception of breakthrough pain;the experience when experiencing breakthrough pain; personal growth related to breakthrough pain. Conclusions Nurses should provide sufficient information to patients timely, consider patients′needs and combine with non-drug methods to better manage breakthrough pain to improve patients′experience about breakthrough pain.
