Aims: This study aimed to explore the relationship between workplace bullying among nurses and their professional quality of life, as well as the mediating role of coping styles between the two factors. Background: In China, the overall status of nurses' professional quality of life is not optimistic, and the problems of low compassion satisfaction and high compassion fatigue persist. Workplace bullying, which is a serious global issue, can negatively impact the mental health and professional quality of nurses. However, it has still not attracted enough attention from managers. Methods: The study used a cross-sectional research design and surveyed 297 clinical nurses from two tertiary grade A hospitals in Wuhan, China. Data were collected through an online questionnaire survey from March to May 2022. The data were analyzed using descriptive statistical methods, including Pearson correlation analysis and structural equation modeling. Results: The score for nurses' workplace bullying was 38.72 ± 12.30. The scores for the three dimensions of professional quality of life were 27.56 ± 4.79 for compassion satisfaction, 30.51 ± 4.33 for burnout, and 28.47 ± 4.65 for secondary trauma stress. The scores for positive coping style and negative coping style were 34.59 ± 5.72 and 20.34 ± 5.08 points, respectively. Workplace bullying had a direct negative effect on compassion satisfaction, as well as positive direct effects on burnout and secondary traumatic stress. Coping styles played a mediating effect between workplace bullying and the pairwise relationships of compassion satisfaction, burnout, and secondary trauma stress. Conclusion: Workplace bullying hurts nurses' professional quality of life while coping styles plays an mediating role between workplace bullying and professional quality of life. Nursing managers can improve nurses' professional quality of life by reducing workplace bullying and enhancing positive coping style. Implications for nursing management: Nursing managers can employ management wisdom and techniques to mitigate the presence and detrimental effects of workplace bullying. This, in turn, promotes a positive work environment and enhances the professional quality of life for nurses. [ABSTRACT FROM AUTHOR]

To retrospectively analyze the off‐label prescriptions at a plastic surgery hospital in China and conduct a literature review. The prescriptions in outpatient department from January 1, 2018 to December 31, 2018 were collected and compared with the related drug instructions in indications, dosage, frequency and route of administration to identify the off‐label prescriptions. According to related literatures, guidelines, and MICROMEDEX, the rationality of off‐label drug uses was evaluated. A total of 39 836 prescriptions were screened and 3395 (8.52%) off‐label prescriptions were identified. It involved 23 items off‐label medication uses. 20 items were off‐label used in indication and three items were in indication and administration route. These off‐label prescriptions involved 19 medicines and 12 indications and the dermatology related drug usage accounted for the largest proportion (91.3%). Additionally, five items (21.7%) were Chinese patent medicine related. Of the 23 items, seven (30.4%) have been recommended by guidelines and two (8.7%) by Thomson Grading System of Micromedex. All of them have been proved by literature evidence of level 1 to 4, in which 19 (82.6%) by Level 1 evidence, 21 (91.3%) by Level 1 to 2 evidence and 2 (8.7%) only by level 3 to 4 evidence. This can provide a theoretical basis to clinicians in prescribing. Our next work is to perfect some details about evidence assessment to improve the reliability. [ABSTRACT FROM AUTHOR]

[Display omitted] • LiCl@CCP-PPy is simple and inexpensive to prepare, with fast water absorption–desorption capacity and cyclic stability. • LiCl@CCP-PPy is a hydrophilic macroporous material with a water absorption capacity of up to 2.86 g/g at 35 % RH and 25 °C. • LiCl@CCP-PPy has good storage capacity and ensures that the salt does not leak. • The water collection rate of LiCl@CCP-PPy in a single hygroscopic-desorption cycle in the Tengger Desert was 0.64 L/m2/d. Solar-driven atmospheric water harvesting (SAWH) has been recognized as a promising strategy to alleviate the freshwater crisis. Herein, we developed an efficient porous polymeric foam, LiCl@CCP-PPy, which has low preparation cost, strong adaptability and portability, and is very suitable for use as a wicking material in SAWH systems. LiCl@CCP-PPy contains abundant –NH 2 and –OH groups. These hydrophilic groups and excellent pore structure (porosity is 80.22 %) make it have a good moisture absorption effect even in low humidity environment. The moisture absorption capacity can reach 2.86 g/g at 35 % RH and 25 °C, and 4.48 g/g at 25 °C and 90 % RH. The saturated water absorption effect was 27.48 g/g. LiCl@CCP-PPy can be scaled up for production. In addition, LiCl@CCP-PPy has a high light absorption rate of more than 90 %, and the strong photothermal conversion ability of Polypyrene (PPy) enables the material to warm up rapidly under natural light, thereby accelerating the desorption process (96 % desorption rate at 1 kW/m2 for 3 h). Based on the above properties, LiCl@CCP-PPy was applied to the Tengger desert in northwest China. The final water production efficiency was 0.64 L/m2/d, and the collected water quality met the international drinking water standard. [ABSTRACT FROM AUTHOR]

Taxon delimitation and identification are important in many areas of biology, especially in taxonomy and conservation. Taxonomic treatment is required to establish and justify recommendations in conservation biology for the group being considered. Imperfect and controversial taxonomy can undermine conservation assessment. We studied 71 populations; 665 individuals corresponding to the morphology of the Rosa sericea complex (including six taxa, one of which has extremely narrow distributions) were collected from sympatric, parapatric, and allopatric populations distributed in China. This study aims to investigate whether the complex species are macromorphologically different species and evaluate the rare taxa of the complex for conservation priority. The morphological characters and principal component analysis (PCA) of the R. sericea complex showed that the complex species have overlapping characters but can distinguish morphologically. The species of R. sericea complex systematics status based on previous DNA sequencing is controversial. The ecological habitat's current morphological characters only delimit the R. morrisonensis (in Taiwan). To evade mistakes in species conservation, we recommend that taxonomical knowledge be needed to ensure success in protecting target species. Thus, the complementarity of systemic and conservation assurance makes conservation actions more necessary for the complex's rare taxa. The ecological niche modelling (ENM) results showed that habitats of these conspecific taxa would be shrunken. With the presence of snapshots in time, the geography of taxa might decrease rapidly in representative entirely of the Geographic space (G-space) and Environmental space (E-space) that such taxa are bright to inhabit. So far, the significant inferences meant for the niche occupy the most incredible comparative research, taking the impermanent nature of taxa distributions and undertaking that such species are at a state of stability. If the artificially identified species (rarely distributed) are based on morphological identification, they must be conserved. [ABSTRACT FROM AUTHOR]

Previous studies indicate that vegetation and lakes in arid and semi-arid regions are closely related to climate change. However, the responses of vegetation and lakes to climate-related variables have rarely been contrastively studied. The Hulun Lake (HLL) and its surrounding grasslands in Northeast Inner Mongolia of China comprise a semi-arid region that has experienced intense climate change over the last several decades. This study aims to understand the key factors that control the variations in the lake area and vegetation cover over the last five decades in the HLL region, as well as contrastively investigate the different responses of the lake area and vegetation cover to climate-related variables. Analysis results indicate that the variations with increasing change rates in the HLL area were mainly controlled by precipitation fluctuation. Moreover, an increase or decrease in the air temperature and relative humidity could affect the response time of the HLL area to the change in precipitation. The Normalized Difference Vegetation Index (NDVI) variations from 1990 to 1999 around the HLL region were mainly controlled by the intense local grazing rather than climatic restrictions. The fluctuation in NDVI after 1999 reflects the response of the vegetation cover to climatic change. The correlation analysis shows that the variations in the HLL area were closely related to the multi-year tendency of precipitation amount and to the Standardized Precipitation Evapotranspiration Index (SPEI) with a long timescale. However, NDVI is sensitive to changes in short-term precipitation amount, such as seasonal precipitation, and in SPEI with a monthly timescale. The soil moisture at shallow depths (< 0.1 m) was the key root–zone soil moisture that could influence NDVI, whereas soil moisture at depths of 0.4 to 1.0 m and the HLL area were closely related and had similar responses to climatic change.

Lead, a ubiquitous heavy metal, can be found in the environment and food. The present study is the first to estimate the lead dietary exposure of Shenzhen adults (≥ 20 years old) in various age-gender subgroups, and to assess the associated health risk. Food samples that represented the Shenzhen people's dietary pattern were collected and prepared for analysis. Lead was determined in 13 food groups using 276 individual cooked samples by inductively coupled plasmamass spectrometry (ICP-MS). Dietary exposures were estimated by combining the analytical results with the local food consumption data of Shenzhen adults. The mean and 95th percentile lead exposure of Shenzhen adults were 0.59-0.73 and 0.75-0.94 µg kg-1 bw day-1, respectively. In all food groups, the highest lead exposure was from 'Eggs and their products' (42.4-51.6% of the total exposure); preserved eggs being the main contributor. The other major contributors to lead exposure of Shenzhen adults were 'Fish and seafood, and their products' (14.3-16.7% of the total exposure) and 'Vegetables and their products' (15.5.16.2% of the total exposure). The margin of exposure (MOE) approach was used for the risk assessment of lead, and the results showed that the risk was considered to be low in all age.gender groups for Shenzhen adults. However, having considered a number of toxic effects of lead, it is suggested that more efforts should be made to reduce the lead levels in foodstuff for Shenzhen adults. [ABSTRACT FROM AUTHOR]

Background: Renal organic ion transporters and uromodulin (UMOD) play the important roles in renal urate excretion and function. Hyperuricemia is considered as a risk factor for the development of renal dysfunction. The flavonoid quercetin in diets exerts the hypouricemic and nephroprotective effects. Purposes: To evaluate the effects of quercetin on renal organic ion transporters and UMOD in hyperuricemic mice. Methods: Kun-Ming mice were divided into normal and hyperuricemic groups receiving water, 25, 50 and 100 mg/kg quercetin, 5 mg/kg allopurinol, respectively. Hyperuricemic mice were orally gavaged with 250 mg/kg oxonate daily for 1 week. Quercetin and allopurinol were orally gavaged on the day when oxonate or water was given 1 h later. After 1 week, serum uric acid, creatinine and blood urea nitrogen concentrations, excretion of urate and creatinine, and fractional excretion of uric acid were measured. The mRNA and protein levels of renal urate transporter 1 (mURAT1), glucose transporter 9 (mGLUT9), organic anion transporter 1 (mOAT1) and organic cation/carnitine transporters (mOCT1, mOCT2, mOCTN1 and mOCTN2) in mice were analyzed. Simultaneously, UMOD levels in serum, urine and kidney, as well as renal UMOD mRNA expression were detected. Results: Quercetin significantly restored oxonate-induced abnormalities of these biochemical indexes compared with normal vehicle group. Furthermore, it remarkably prevented expression changes of renal organic ion transporters and UMOD, and UMOD level alteration in hyperuricemic mice. Conclusions: These results suggest that quercetin has the uricosuric and nephroprotective actions mediated by regulating the expression levels of renal organic ion transporters and UMOD.
