摘要：
It investigates compliance quality improvement and carbon reduction in the fuel vehicle supply chain. In our model, a manufacturer with carbon social responsibility first determines the level of carbon reduction, vehicle fuel consumption reduction, and compliance quality improvement. Multiple retailers then select the level of marketing effort. The analysis of decentralized, cost-sharing, and revenue-sharing decisions shows that the ranking of carbon and fuel consumption reduction and compliance quality improvement under the three models depends on the parameters. Cost-sharing and revenue-sharing can improve the utility of supply chain members, but the sharing modes that they prefer are different.

摘要：
BACKGROUND: Chloride is the most abundant anion in the human extracellular fluid and plays a crucial role in maintaining homeostasis. Previous studies have demonstrated that hypochloremia can act as an independent risk factor for adverse outcomes in various clinical settings. However, the association of variances of serum chloride with long-term mortality risk in general populations has been rarely investigated. OBJECTIVE: This study aims to assess the association of serum chloride with all-cause and cause-specific mortality in the general American adult population. METHODS: Data were collected from 10 survey cycles (1999-2018) of the National Health and Nutrition Examination Survey. All-cause mortality, cardiovascular disease (CVD) mortality, cancer mortality, and respiratory disease mortality data were obtained by linkage to the National Death Index through December 31, 2019. After adjusting for demographic factors and relevant lifestyle, laboratory items, and comorbid factors, weighted Cox proportional risk models were constructed to estimate hazard ratios and 95% CIs for all-cause and cause-specific mortality. RESULTS: A total of 51,060 adult participants were included, and during a median follow-up of 111 months, 7582 deaths were documented, 2388 of CVD, 1639 of cancer, and 567 of respiratory disease. The weighted Kaplan-Meier survival analyses showed consistent highest mortality risk in individuals with the lowest quartiles of serum chloride. The multivariate-adjusted hazard ratios from lowest to highest quartiles of serum chloride (≤101.2, 101.3-103.2, 103.2-105.0, and ≥105.1 mmol/L) were 1.00 (95% CI reference), 0.77 (95% CI 0.67-0.89), 0.72 (95% CI 0.63-0.82), and 0.77 (95% CI 0.65-0.90), respectively, for all-cause mortality (P for linear trend<.001); 1.00 (95% CI reference), 0.63 (95% CI 0.51-0.79), 0.56 (95% CI 0.43-0.73), and 0.67 (95% CI 0.50-0.89) for CVD mortality (P for linear trend=.004); 1.00 (95% CI reference), 0.67 (95% CI 0.54-0.84), 0.65 (95% CI 0.50-0.85), and 0.65 (95% CI 0.48-0.87) for cancer mortality (P for linear trend=.004); and 1.00 (95% CI reference), 0.68 (95% CI 0.41-1.13), 0.59 (95% CI 0.40-0.88), and 0.51 (95% CI 0.31-0.84) for respiratory disease mortality (P for linear trend=.004). The restricted cubic spline analyses revealed the nonlinear and L-shaped associations of serum chloride with all-cause and cause-specific mortality (all P for nonlinearity<.05), in which lower serum chloride was prominently associated with higher mortality risk. The associations of serum chloride with mortality risk were robust, and no significant additional interaction effect was detected for all-cause mortality and CVD mortality (P for interaction>.05). CONCLUSIONS: In American adults, decreased serum chloride concentrations were independently associated with increased all-cause mortality, CVD mortality, cancer mortality, and respiratory disease mortality. Our findings suggested that serum chloride may serve as a promising cost-effective health indicator in the general adult population. Further studies are warranted to explore the potential pathophysiological mechanisms underlying the association between serum chloride and mortality.
摘要：
The governance of uranium tailings aims to improve stability and reduce radionuclide uranium release. In order to achieve this goal, the uranium removal solution test and uranium tailings grouting test were successively carried out using microbially induced calcium carbonate precipitation (MICP) technology.The effect of MICP on the reinforcement of uranium tailings and the synchronous control of radionuclide uranium in the tailings were discussed. The solution test results show that Sporosarcina pasteurii could grow and reproduce rapidly in an acidic medium with an initial pH of 5. The uranium concentration decreased with the increase in MICP reaction time, and the removal efficiency reached 60.9% at 24 h. In the solidification test of tailings, the strength of tailings improved significantly after 12 days of reinforcement, with an increase in the cohesion of tailings by 2.937 times and an increased internal friction angle of 8.393(?). The peak stress value of solidified tailings at the surrounding pressure of 50 kPa increased by 1.87 times, and the uranium concentration in the discharge fluid decreased by 76.91% compared to the blank group. This study provides valuable insights and references for safely disposing of uranium tailings.
摘要：
To effectively understand the collaborative and evolutionary mechanisms of three stakeholders in carbon trading namely, government, emission reduction enterprises, and emission control enterprises, it is important to identify the factors that affect decision-making behaviors amongst game players, ultimately contributing to the goal of "double carbon". In this study, we constructed a tripartite game model, analyzing the selection mechanism for game strategies related to carbon trading participants through replicated dynamic equations. We also discussed the main factors that influence the evolutionary and stable outcomes of carbon trading through scenario simulations. Additionally, we introduced prospect theory to examine the impact of risk sensitivity and loss avoidance levels amongst decision-makers on the optimal outcome of the system. Our findings reveal that in the initial game model, the three decision-makers show a cyclical behavior pattern, but the system stabilizes in the optimal equilibrium state (1,1,1) when certain conditions are satisfied. Furthermore, the initial willingness of decision-makers impacts the ability of the game system to reach a stable point. Moreover, larger values for the risk sensitivity coefficient and loss avoidance coefficient can promote the evolution of the game system toward an optimal, stable point. Based on these results, targeted countermeasures are proposed to promote activity within the carbon trading market, such as giving more institutional guarantees to carbon trading and stabilizing the carbon price.

Based on the pressure of environmental protection, more and more scientific researchers are trying to reuse aluminum-silicon-rich industrial wastes. In this study, activated lithium-slag and lead-zinc tailings were used as raw materials to prepare geopolymers at ratios of 3:7, 1:1, and 7:3. These geopolymers were initially cured for 12 h at 25 degrees C, 50 degrees C, 75 degrees C, and 100 degrees C and were then cured at room temperature to the specified ages. The compressive strength of each group of geopolymers was tested at the ages of 3 days, 7 days, and 28 days. The optimal group of samples was selected, that is, those with a ratio of lithium-slag to lead-zinc tailings of 7:3 and an initial curing temperature of 75 degrees C. After that, the heavy metal leaching test and porosity analysis test were carried out on the optimal group of samples, and the curing effect was considered to meet the requirements of the Chinese specifications. In addition, in order to reveal the mechanism of the chemical reaction, scanning electron microscopy and X-ray diffraction (XRD) were used to study the microstructure and hydration products of the C3 group cured samples. This study provides a new concept for the reuse of industrial wastes such as lithium-slag and fine-tailings.
摘要：
Inter-regional trade in commodities causes the flow of water pollutants, referred to as virtual pollutant transfer. However, existing studies usually focus on a single water pollutant and cannot characterize the integrated discharge of multiple ones. As a result, it is impossible to analyze the integrated virtual flow of multiple water pollutants among regions, much less simulate the effects of possible water pollutant reduction scenarios. To this end, we empirically synthesize several water pollutant indicators as a whole and then make it the occupancy in the framework of input-output analysis, which helps us to quantify the virtual transfer of water pollutants and simulate scenarios' mitigating effects. The constructed indicator is called the synthetic water pollutant (SWP) discharge index. By accounting for SWP and then its virtual flows based on the compiled multi-regional input-output tables, we analyze the temporal and spatial differences in synthetic net virtual transfer of regional multiple water pollutants occurring with inter-regional trade. The results show that the national SWP discharge scale of six water pollutants (chemical oxygen demand, ammonia nitrogen, total nitrogen, total phosphorus, petroleum, and volatile phenol) is falling from 2012 to 2020. The net intake of virtual pollutants has become more concentrated. Central (e.g., Shanxi and Hunan) and western (Xinjiang, Inner Mongolia) China are the central regions of net virtual receiving. The simulation results show that reducing 10% of importing regions' inputs while cutting 10% of exporting regions' consumption mitigates the SWP discharge of the entire economic system by 3.45%. The decrease rate is 3.02%, increasing international imports by 10% in all regions. An incremental SWP reduction of 2.75% by reducing SWP discharge per output unit by 10% in the top 10 regions of discharge intensity indicates reducing the SWP discharge intensity is the most direct and effective approach. However, the growth of fixed asset investment in wastewater treatment and its recycling seems to contribute little to achieving China's policy target of wastewater treatment capacity increase by 2025. This study provides regional results for managing water pollutants in China and a basis for future policymaking.

摘要：
Phosphonic acid functionalization of gellan gum and chitosan biopolymers was successfully performed. In the first step, the sorption was investigated using La(III) ions before testing for the recovery of rare earth elements (REEs) from pretreated industrial acidic leachate. The sorbent was characterized by Fourier-transform infrared (FTIR), scanning electron microscopy with energy dispersive X-ray analysis (SEM-EDX), thermogravimetric analysis (TGA), Brunauer-Emmett-Teller (BET), and pH of zero charge (pH(PZC)) determination. FTIR and EDX results show efficient grafting of phosphoryl groups. The sorption was determined for the crude materials before functionalization (PGEG) and after phosphorylation (TBP-PGEG). More efficient sorption was seen for phosphorylated sorbent than for the crude composite. The sorption capacity is 0.226 mmol La g(-1) for the PGEG while the value is 0.78 mmol La g(-1) for the TBP-PGEG. We infer that phosphonate groups participate in the sorption. The most effective sorption is at pH = 4. The kinetic behavior was described using pseudo first-order equations (PFORE), pseudo second-order equations (PSORE), and resistance to intraparticle diffusion (RIDE). The sorption isotherms can be better represented by Langmuir and Sips equations than by the Freundlich equation. The sorbent shows high stability performance during reuse cycles with a limit on the decrease in the sorption performances and stability in the desorption performances. We have thus developed a good tool for the recovery of REEs with a selectivity higher than that of the non-functionalized components.

摘要：
BACKGROUND: Douyin APP is the short video APP with the largest number of users in China. OBJECTIVE: This study aimed to evaluate the quality and reliability of short videos about cosmetic surgery on Douyin. METHODS: In August 2022, we retrieved and screened 300 short videos related to cosmetic surgery from Douyin, extracted basic video information, encoded the contentand identified the video source. The quality and reliability of short video information were evaluated using the DISCERN instrument. RESULTS: A total of 168 short videos of cosmetic surgery were included in the survey, and the video sources included personal accounts and institutional accounts. Overall, the total proportion of institutional accounts (47/168, 27.98%) is significantly less than that of personal accounts (121/168, 72.02%); nonhealth professionals received the most praises, comments and even collections and reposts, while for-profit academic organizations or institutions received the least. The DISCERN scores of 168 short videos of cosmetic surgery were 3.74-4.58 (average 4.22). Content reliability (p = .04) and overall short video quality (p = .02) are significantly different, but short videos published from different sources have no significant difference in treatment selection (p = .052). CONCLUSION: The overall information quality and reliability of short videos about cosmetic surgery on Douyin are satisfactory in China. PATIENT OR PUBLIC CONTRIBUTION: The participants were involved in developing research questions, study design, management and conduct, interpretation of evidence and dissemination.

摘要：
Considering the financial coordination and investment cost sharing between the members, this paper studies the conformance quality improvement, carbon reduction, and green marketing optimal decisions of a green supply chain composed of one manufacturer and multiple retailers. The retailer is either cash-strapped, cash-rich, or both. By using the Stackelberg game method, we obtain the equilibrium results of the game in the three cases. The results show that financial coordination should be implemented between the manufacturer and the three types of retailers. However, only with the second type of retailer can cost-sharing increase the profitability of both sides.

摘要：
This review aimed to appraise clinical guidelines about exercise for women with gestational diabetes mellitus and summarize consensus and inconsistent recommendations.
Exercise is an effective non-pharmacological therapeutic for gestational diabetes mellitus, but the variety of relevant clinical practice guidelines is confusing for healthcare professionals.
This is a systematic review of clinical practice guidelines.
Websites of guideline development institutions, eight literature databases and organizations of obstetricians, gynaecologists, midwives, and medical sports associations were searched for guidelines published from January 2011 to October 2021.
Two reviewers independently extracted recommendations. Four reviewers assessed guideline quality using the AGREE II instrument independently.
Fifteen guidelines were included. All women with diabetes are recommended to exercise during pregnancy. The consistent recommendations were for pre-exercise screening, for 30 min per exercise session on 5 days of the week or every day after meals, exercise at moderate intensity, using aerobic and resistance exercise, and walking. The main non-consistent recommendations included warning signs for women on insulin during exercise, minimum duration per session, intensity assessment, duration and frequency of sessions for strengthening and flexibility exercise and detailed physical activity giving birth.
Guidelines strongly support pregnant women with diabetes to exercise regularly. Research is needed to make non-consistent recommendations clear.

摘要：
Glycemic control is an important issue in the treatment of diabetic patients. However, traditional methods, such as medication (the usual treatment), have limitations. Cognitive behavioral therapy (CBT) might be a useful option to help control the glycemic condition. The effects can be revealed by systemic review or meta-analysis of randomized clinical trials (RCT). A systematic search and a meta-analysis for the RCT were done of the short- and long-term effects of CBT on the glycemic control of diabetic patients in a comparison with the usual treatment. Nineteen RCT studies and 3,885 diabetic patients were enrolled in this meta-analysis. Subgroup analyses of types 1 and 2 diabetes and individual and group CBT were also performed. Patients treated with CBT showed no significant difference in HbA1c when compared to the usual treatment within six months. However, CBT was more effective in reducing HbA1c when compared to usual treatment with at least six months of treatment duration [standardized mean difference: -0.44 (95% confidence interval (CI): -0.63 ~ -0.25), Z = 4.49]. Subgroup analysis of type 1 and 2 diabetic patients supported a long-term effect of CBT on glycemic control [standardized mean difference: -0.85 (95% CI: -1.19 ~ -0.10), Z = 2.23, standardized mean difference: -0.33 (95% CI:-0.47 ~ -0.19), Z = 4.52, respectively]. CBT would be a useful option for improving the glycemic control of diabetic patients undergoing long-term treatment. The advantages of the long-term effects of CBT should be considered by clinicians and staff.
摘要：
Trans-urocanic acid (UCA), an isomer of cis-UCA that is mainly located in the skin, has recently been reported to have a role in short-term working memory and in the consolidation, reconsolidation and retrieval of long-term memory. However, its effect on memory acquisition remains unclear. In the present study, the effect of UCA on short-term and long-term memory acquisition in mice was investigated using novel object recognition (NOR) and object location recognition (OLR) protocols that each involved three stages: habituation, sampling and testing. UCA was intraperitoneally injected 0.5h pre-sampling, and the discrimination index during subsequent testing was determined in NOR and OLR tasks. The results showed that 10mg/kg UCA significantly facilitated short-term and long-term memory acquisition in both types of tasks. Furthermore, 30mg/kg UCA significantly facilitated long-term memory acquisition in the NOR task and tended to facilitate long-term memory acquisition in the OLR tasks but did not facilitate short-term memory acquisition in either task. Additionally, the enhancing role of UCA on memory acquisition was not dependent on changes of nonspecific responses, e.g. exploratory behavior and locomotor activity. The current study suggests that UCA facilitates short-term and long-term recognition memory acquisition, which further extends the functional role of UCA in the brain function.

Moral identity;Silence behavior;Felt obligation towards organization;Corporate social responsibility perception;Self-verification theory
摘要：
As a common organizational phenomenon, employee silence behavior has various negative implications for organizations, making it critical to understand what factors can reduce employee silence. Drawing upon self-verification theory, this study explores the inhibiting effect of moral identity on silence via felt obligation towards organization. Meanwhile, we also examine the moderating effect of corporate social responsibility perception. We collected three waves of data with a two-month interval from 402 Chinese employees. Results indicated that moral identity positively predicted felt obligation towards organization, which in turn negatively predicted silence behavior. The negative indirect effect of moral identity on silence behavior via felt obligation towards organization was moderated by corporate social responsibility perception. Specifically, this indirect effect was stronger when employees perceived a higher level of corporate social responsibility. By integrating self-verification theory with silence behavior research, our findings provide important insights into the prevention of employee silence behavior in organizations.

摘要：
With increasing urbanization in China, the traffic-induced urban environmental noise pollution problem is becoming more and more serious, and it has become a common urban malady that cannot be ignored. Traffic green belts are an important part of the urban ecosystem and play a role in traffic noise reduction, and simultaneously provide ecosystem services, such as creating a natural landscape and retaining dust. Therefore, they are a category of Nature-based Solutions (NbSs) that have multiple ecosystem service provisions. The relationship between NbSs and urban ecosystem services is one of the current research hot spots. However, regarding the assessment of ecosystem services on the urban scale, the role of vegetation in reducing noise pollution as a service has rarely been studied. Taking Shenzhen City as an example, through monitoring 217 sample plots in the city, this paper analyzes the relationship between vegetation coverage and the ability of green belts to reduce noise by using the IUEMS platform combined with the high-resolution spatial distribution data of green spaces. Then, we evaluated the product amount and the value of the roadside green belts in Shenzhen when acting as a noise reduction service. The work of this study, to a certain extent, improves the problems related to the inadequate consideration of vegetation characteristics in current urban-scale noise assessment models. The results show the following: (i) In the respective analysis buffer zones of the Grade I to Grade IV roads in Shenzhen, on average, for every 1% increase in the vegetation coverage of green belts, noise can be reduced by 0.4 dB, 1.0 dB, 0.2 dB, and 0.6 dB, respectively. (ii) The product value of the noise reduction service provided by roadside green belts is CNY 1.16 billion in Shenzhen. (iii) The road traffic noise greatly exceeds the standard in Shenzhen, but traffic noise can be decreased by increasing the vegetation coverage of green belts. This is not only beneficial to the scientific understanding of the ecological service value of green spaces by evaluating the noise reduction service of traffic green belts, as well as its influencing factors, but is also beneficial to making improvements in construction and management ideas for urban green spaces.

摘要：
Using accurate assessment tools to assess patients in clinical practice is important to mining influencing factors and implementing interventions. However, most evaluation tools for the self-management of elderly patients with hypertension lack a theoretical basis and wide applicability, which makes the intervention effect insignificant. Based on the Capability, Opportunity, and Motivation-Behaviour (COM-B) model, combined with literature review and qualitative research, a questionnaire item pool was initially formulated; then the initial items were screened and adjusted through expert consultation and pre-testing to form an initial scale. A field survey of 450 elderly hypertensive patients was then performed using the initial scale to test the reliability and validity of the scale. Cronbach’s alpha, test–retest reliability and composite reliability were used to test the reliability of the scale, and the validity of the scale was evaluated from two aspects: content validity and construct validity. The evaluation results of the content validity of the scale by experts were used as the content validity index; the results of exploratory factor analysis and confirmatory factor analysis were used as the structural validity index to further verify the model structure of the scale and develop a formal scale. The final self-management scale included 4 dimensions and 33 items. The Scale-Content Validity Index was 0.920. Exploratory factor analysis extracted four factors that explained 71.3% of the total variance. Cronbach’s alpha of the formal scale was 0.867, test–retest reliability was 0.894, and composite reliability of the 4 dimensions were within 0.943 ~ 0.973. Confirmatory factor analysis showed the scale had good construct validity. The Self-management Capability, Support and Motivation-Behaviour scale for elderly hypertensive patients has good reliability and validity, providing a tool for medical staff to evaluate the self-management level of elderly hypertensive patients.
