Objectives To investigate the correlation between dietary fatty acids intake of pregnant women and neonatal anthropometry at birth. Methods Women in early pregnancy were recruited with appropriate value of weight gain in pregnancy. Instant photography was used to assess the dietary situation in both the second trimester and the third trimester to calculate the intakes of food, energy, macronutrients, and fatty acids. The body weight, height and BMI at birth were evaluated with Z scores. The correlation between dietary fatty acids of pregnant women and neonatal anthropometry at birth were analyzed. Results There were 516 pregnant women recruited in this study. The average intakes of polyunsaturated fatty acids (PUFA) and the proportion of total fatty acids in the two trimesters were 15 . 09 g/d, 23 . 93% and 17 . 18 g/d, 24 . 86%. In the second trimester the intakes of n-6 and n-3 PUFA were 14 . 23 g/d and 3 . 45 g/d, and in the third trimester, n-6 and n-3 PUFA were 16 . 08 g/d and 3 . 81 g/d, the average intakes in the third trimester were signiifcantly higher than those in the second trimester (P??0 . 05 ). The intake of DHA ( 64 . 43 mg/d) in the second trimester was lower than that in the third trimester 75 . 12 mg/d, (P??0 . 05 ).The dietary intakes of n-3 PUFA, n-6 PUFA and n-6/n-3 ratio in the second trimester were positively correlated with neonatal BMI r=0 . 142~0 . 189 , P??0 . 05 ). Conclusions The dietary ratio of n-6/n-3 PUFA in the second trimester was positively correlated with neonatal BMI, suggesting that moderately increasing the intake of n-3 PUFA may play a positive role in reducing childhood obesity.

Objective:To explore the current situation of clinical nurses' disaster nursing ability and its influencing factors, and to provide basis for carrying out clinical nurses' disaster nursing education and training.Methods:By convenient sampling method, 322 clinical nurses from Peking University Shenzhen Hospital in September 2020 were selected. The disaster nursing ability assessment tool and general information questionnaire were used to conduct a questionnaire survey to analyze the current situation of clinical nurses' disaster nursing ability and its main influencing factors.Results:The total score of disaster nursing ability of clinical nurses was (199.07±34.31) points, which was at the middle and lower level; the scores of each dimension from high to low were as follows: disaster preparedness score was (72.94±12.89) points, coping ability score was (80.00±13.82) points, disaster reduction/prevention capability score was (28.19±6.09) points, recovery/reconstruction ability score was (17.94±3.27) points. Regression analysis showed that the highest degree, clinical department, whether they have autonomously studied disaster nursing related courses after work, and whether they have participated in disaster rescue after work were the main influencing factors of clinical nurses' disaster nursing ability ( t values were -4.715-5.508, P<0.05). Conclusions:The overall level of disaster nursing ability of clinical nurses is at the middle and lower level. It should be combined with clinical nurses' work department, whether clinical nurses have disaster rescue experience and whether they have independently studied disaster nursing related courses, and targeted disaster nursing related training should be carried out to improve their disaster nursing knowledge and skill.

Objective To investigate the effect of tiaozhi granules on the autophagy of HU-VECs in the cell,protein and molecular levels.Methods HUVECs were induced by tiaozhi granule medicated serum,6-amino-3-methyl purine (3-MA) and rapamycin.MTT was used to detect the cell viability after 48 hours with tiaozhi granule medicated serum.Western blot was used to detect the expressive level of LC3-Ⅱ.Immunofluorescence was used to detect change in the numbers of autophagosomes.Results After HUVECs was processed by tiaozhi granule medicated serum,the cell viability had not change,the relative expression of autophagy related protein LC3-Ⅱ increased,and the number of autophagosomes increased (P ＜ 0.05).After HUVECs was processed by tiaozhi granule medicated serum and rapamycin,cell viability had no change,while the relative expression of autophagy related protein LC3-Ⅱ and the number of autophagosomes decreased significantly when compared with the results of intervention with rapamycin only (P ＜ 0.05 or P ＜ 0.01).Conclusion Tiaozhi granules can inhibit excessive autophagy of endothelial cells and promote moderate autophagy in endothelial cells.

Objective:To systematically evaluate the real experience of living related organ transplantation donors from relatives and provide evidence-based basis for medical and nursing staff to develop personalized intervention measures.Methods:Qualitative study on the real experience of living related organ transplantation donors from relatives was searched on PubMed, Web of Science, Cochrane Library, Embase, China National Knowledge Infrastructure, WanFang Data, VIP, and Biology Medicine disc. The search period was from database establishment to August 31, 2022. The article was evaluated using the quality evaluation criteria for qualitative study of the Australian Joanna Briggs Institute (JBI) Evidence-Based Healthcare Center. We converged the results and performed Meta-synthesis.Results:A total of 15 articles were included, 32 research results were extracted, and summarized and integrated into 13 new categories. A total of 5 integration results were synthesized, including the motivation to donate, the pressure and challenges faced before transplantation, the physical and mental discomfort caused by donation, the positive impact of donation, and the desire for support and needs from various aspects.Conclusions:Donors of living related organ transplantation have multiple psychological experiences during the process of organ donation. Nurses should dynamically assess the pressure and challenges faced by donors, provide diverse support to meet their needs, help donors actively respond, and improve their quality of life.

Objective To analyze the interactions between different structural types of volatile oil compo-nents(VOCs)and skin lipid molecules,and investigate the mechanism of volatile oil in Chi-nese materia medica(VOCMM)as penetration enhancers. Methods In this study,210 different structural types of VOCs were selected from the VOCMM penetration enhancer database,and the molecular docking experiments were conducted with three main lipid molecules of skin:ceramide 2(CER2),cholesterol(CHL),and free fatty acid(FFA).Each VOC was docked individually with each lipid molecule.Cluster analysis was used to explore the relationship between the binding energy of VOCs and their molecular struc-tures.Nine specific pathogen-free(SPF)Sprague Dawley(SD)rats were randomly divided in-to Control,Nootkatone,and 3-Butylidenephthalide groups for in vitro percutaneous experi-ments,with three rats in each group.The donor pool solutions were 3%gastrodin,3%gas-trodin+3%nootkatone,and 3%gastrodin+3%3-butylidenephthalide,respectively.The pen-etration enhancing effects of VOCs with higher binding energy were evaluated by comparing the 12-hour cumulative percutaneous absorption of gastrodin(Q12,μg/cm2). Results(i)Most of the VOCs were non-hydrogen bonded to the hydrophobic parts of CHL and FFA,and hydrogen bonded to the head group of CER2.Among them,sesquiterpene ox-ides showed the most pronounced binding affinity to CER2.The VOCs with 2-4 rings(in-cluding carbon rings,benzene rings,and heterocycles)demonstrated stronger binding affini-ty for three skin lipid molecules compared with the VOCs without intramolecular rings(P<0.01).(ii)According to the cluster analysis,most of the VOCs that bond well to CER2 had 2-3 intramolecular rings.The non-oxygenated VOCs were bonded to CER2 in a hydrophobic manner.The oxygenated VOCs were mostly bonded to CER2 by hydrogen bonding.(iii)The results of Franz diffusion cell experiment showed that the Q12 of Control group was 260.60±25.09 μg/cm2,and the transdermal absorption of gastrodin was significantly increased in Nootkatone group(Q12=5 503.00±1 080.00 μg/cm2,P<0.01).The transdermal absorption of gastrodin was also increased in 3-Butylidenephthalide group(Q12=495.40±56.98 μg/cm2,P>0.05).(iv)The type of oxygen-containing functional groups in VOCs was also an influencing factor of binding affinity to CER2. Conclusion The interactions between different types of VOCs with different structures in the VOCMM and three skin lipid molecules in the stratum corneum were investigated at the molecular level in this paper.This research provided theoretical guidance and data support for the screening of volatile oil-based penetration enhancers,and a simple and rapid method for studying the penetration-enhancing mechanism of volatile oils.
