OBJECTIVE: This study aims to examine the parallel multiple mediators of depressive symptoms and sleep quality in the relations between stress and physical health-related quality of life (PHQOL)/mental health-related quality of life (MHQOL) among the women in late pregnancy. METHODS: Of 1120 pregnant women participated in the cross-sectional study which consisted of Perceived Stress Scale, Edinburgh Postnatal Depression Scale, Pittsburgh Sleep Quality Index and MOS 12-item Short Form Health Survey. Parallel multiple mediator models were used to analyze the relations between stress, depressive symptoms, sleep quality and PHQOL/MHQOL. RESULTS: The effect of perceived stress on PHQOL was partially through the indirect path of sleep quality (β=-0.061). But in the model for MHQOL, depressive symptoms and sleep quality played parallel mediators, and the indirect path effect of depressive symptoms (β=-0.179) was higher than sleep quality (β=-0.029). CONCLUSION: The findings contributed to the understanding about the influential mechanism of stress on PHQOL/MHQOL. And it reminded the importance of sleep quality and depressive symptoms for improving QOL in late pregnancy.

ObjectiveThe hygroscopic properties of Mume Flos decoction pieces were studied from the perspectives of macroscopic[water activity(Aw)] and microscopic(water molecular mobility), which provided a theoretical basis for the determination of the safe storage moisture content. MethodAdsorption isotherm of Mume Flos decoction pieces was obtained by static weighing method, and seven common hygroscopic models were fitted and estimated. The best model was selected according to the principle that determination coefficient(R2) was closer to 1, residual sum of squares(RSS) was closer to 0 and Akaike information criterion(AIC) was smaller. According to the optimal model, the absolute and relative safe moisture contents of Mume Flos decoction pieces at 25, 35, 45 ℃ was calculated. Low-field nuclear magnetic resonance(LF-NMR) was used to measure the water molecular mobility in the hygroscopic process of Mume Flos decoction pieces. ResultThe best model to describe the adsorption isotherm of Mume Flos decoction pieces was the Peleg model. According to the model expression, the absolute safe moisture contents of Mume Flos decoction pieces at 25, 35, 45 ℃ were 9.59%, 7.96% and 7.68%, and the relative safe moisture contents were 13.05%, 11.99%, 11.77%, respectively. Mume Flos decoction pieces all contained two water states during the process of hygroscopic absorption at different temperatures, namely bound water T21 and free water T22. During the process of hygroscopic absorption, bound water had the largest increase in peak area. The sum of peak areas of the bound water and free water had a good linear relationship with the moisture contents, and the R2 were 0.959 9, 0.911 8 and 0.974 7 at 25, 35, 45 ℃, respectively. When Aw<0.57, T21 did not change, and the water molecular mobility remained unchanged. When Aw>0.57, T21 showed an increasing trend, and the water molecular mobility increased. The moisture contents of Mume Flos decoction pieces were 8.44%, 6.81% and 6.25% when the water molecular mobility increased at 25, 35, 45 ℃, respectively. ConclusionCombined with the theory of water activity and water molecular mobility, 6.25% is recommended as the safe storage moisture content of Mume Flos decoction pieces, this study can provide reference for determining the safe storage moisture content of other decoction pieces.

ObjectiveTo investigate the differences in health empowerment, perceived control and experiential avoidance between patients with coronary heart disease (CHD) with type D personality and non-type D personality. MethodsFrom January to October, 2022, using the convenient sampling method, a questionnaire survey was conducted on 195 patients with CHD from Affiliated Hospital of Shandong Second Medical University. Assessment tools included Type D Personality Scale, Chinese Version of Patient Perception Empowerment Scale (CV-PPES), Control Attitudes Scale-Revised (CAS-R) and Acceptance Action Questionnaire-II (AAQ-II). ResultsA total of 185 effective questionnaires were returned, and 68 patients with type D personality. Compared with the patients with non-type D personality, the scores of negative affectivity and social inhibition were higher (|t| > 9.783, P < 0.001), the total score of CV-PPES and the scores of four dimensions (information, decision, individual and self-management) were lower (t > 5.843, P < 0.001), the score of CAS-R was lower (t = 2.858, P = 0.005), and the score of AAQ-II was higher (t = -9.414, P < 0.001) in CHD patients with type D personality. ConclusionCompared with non-D-type patients, CHD patients with D-type personality exhibit lower levels of health empowerment and perceived control, and higher level of experiential avoidance, which may negatively impact on health behaviors.

ObjectiveTo conduct on-site epidemiological investigation, emergency response, tracing of infection source and analysis of a confirmed COVID-19 case of a foreign airline cargo service staff member in Shanghai’s international airport, aiming to provide reference for prevention of imported COVID-19 cases under regular prevention and control of COVID-19. MethodsA retrospective field epidemiological investigation was conducted to collect information of basic characteristics, illness onset, diagnosis, treatment, clinical manifestations, exposure history and risk factors within 14 days before onset, close contacts, close contacts of close contacts, and key places related to activity trajectories. Respiratory tract specimens of cases and contacts were collected for detection of SARS-CoV-2 by real time RT-PCR (rRT-PCR). Emergency response, including infection source analysis and contact management, was conducted. ResultsThe case developed pharyngeal itch on July 28, 2021, and fever on the 30th, and went to the hospital for treatment twice on the 31st. Because his specimen was positive for SARS-CoV-2 by rRT-PCR on August 1, he was isolated and treated on August 2 and diagnosed as a confirmed case of COVID-19. The case was a foreign airline cargo service member at an international airport. The two regular nucleic acid screenings of him as a high-risk occupation on July 21 and 28 were negative. He did not leave Shanghai within 14 days before the onset of illness. During July 22nd and 23rd, he was repeatedly exposed during work to the high-risk environment that may have been contaminated by SARS-CoV-2 and had contact with the crew of foreign airlines, and the personal protection was not standardized. None of the 67 close contacts and 567 close contacts of close contacts in Shanghai showed symptoms during the 14-day medical quarantine, and the specimens of them were all negative for SARS-CoV-2 by rRT-PCR. The results of genome sequencing analysis showed that the genomic homology between the virus of the case and the one of recent domestic local epidemic and the recent imported cases was low, and the homology with the overseas Delta mutant strain was higher than that of the domestic Delta mutant strain. ConclusionThe situation of prevention of COVID-19 import is still serious. It is necessary to conduct regular nucleic acid screening for high-risk occupational groups, strengthen the diagnosis and reporting awareness of medical institutions, effectively implement the prevention and control measures for people, objects, and environment at international airports, and further enhance the public's awareness of personal protection.
