RESUMO
BACKGROUND: Acute coronary syndrome(ACS) is the leading cause of mortality and disability worldwide. Immune response has been confirmed to play a vital role in the occurrence and development of ACS. The objective of this prospective, multicenter, observational study is to define immune response and their relationship to the occurrence and progressive of ACS. METHODS: This is a multicenter, prospective, observational longitudinal cohort study. The primary outcome is the incidence of major adverse cardiovascular events (MACE) including in-stent restenosis, severe ventricular arrhythmia, heart failure, recurrent angina pectoris, and sudden cardiac death, and stroke one year later after ACS. Demographic characteristics, clinical data, treatments, and outcomes are collected by local investigators. Furthermore, freshly processed samples will be stained and assessed by flow cytometry. The expression of S100A4, CD47, SIRPα and Tim-3 on monocytes, macrophages and T cells in ACS patients were collected. FOLLOW-UP: during hospitalization, 3, 6 and 12 months after discharge. DISCUSSION: It is expected that this study will reveal the possible targets to improve the prognosis or prevent from occurrence of MACE in ACS patients. Since it's a multicenter study, the enrollment rate of participants will be accelerated and it can ensure that the collected data are more symbolic and improve the richness and credibility of the test basis. ETHICS AND DISSEMINATION: This study has been registered in Chinese Clinical Trial Registry Center. Ethical approval was obtained from the Affiliated Hospital of Guizhou Medical University. The dissemination will occur through the publication of articles in international peer-reviewed journals. TRIAL REGISTRATION: Chinese Clinical Trial Registry: ChiCTR2200066382.

By revealing the temporal and spatial differentiation of China's regional tourism carbon emissions and its decoupling relationship with tourism economic growth and identifying the key factors affecting tourism carbon emissions, this paper is expected to provide a reference for the formulation and implementation of China's regional tourism industry emission reduction policies and measures. Using the tourism's carbon emission data of 30 provinces (cities) in China from 2007 to 2019, we have established a logarithmic mean Divisia index (LMDI) model to identify the main driving factors of carbon emissions related to tourism and a Tapio decoupling model to analyze the decoupling relationship between tourism's carbon emissions and tourism-driven economic growth. Our analysis suggests that China's regional tourism's carbon emissions are growing significantly with marked differences across its regions. Although there are observed fluctuations in the decoupling relationship between regional tourism's carbon emissions and tourism-driven economic growth in China, the data exhibit a primary characteristic of weak decoupling. Nonetheless, the degree of decoupling is rising to various extents across regions. Three of the five driving factors investigated are also found to affect emissions. Both tourism scale and tourism consumption lead to the growth of tourism's carbon emissions, while energy intensity has a significant effect on reducing emissions. These effects differ across regions.

Background: Patients with rheumatoid arthritis (RA) may be more susceptible to infection by coronavirus disease-19 (COVID-19) due to immune system dysfunction. However, there are still insufficient treatment strategies for patients with RA and COVID-19. Since Jingulian is a traditional Chinese medicine (TCM) with anti-viral and immune regulatory functions, our study aims to explore the detailed mechanisms of Jingulian in treating patients with RA and COVID-19. Methods: All the components of Jingulian were retrieved from pharmacology databases. Then, a series of network pharmacology-based analyses and molecular docking were used to understand the molecular functions, core targets, related pathways, and potential therapeutic targets of Jingulian in patients with RA/COVID-19. Results: A total of 93 genes were identified according to the disease-compound-target network. We investigated that the main targets, signaling pathways, and biological functions of Jingulian in RA and COVID-19. Our results indicated that Jingulian may treat patients with RA/COVID-19 through immune processes and viral processes. Moreover, the results of molecular docking revealed that tormentic acid was one of the top compounds of Jingulian, which had high affinity with Janus kinase 1 (JAK1), signal transducer and activator of transcription 3 (STAT3), and epidermal growth factor receptor (EGFR) in patients with RA/COVID-19. Furthermore, 5 core targets of Jingulian were also identified, including JAK1, Janus kinase 2 (JAK2), STAT3, lymphocyte specific protein tyrosine kinase (LCK), and EGFR. Conclusions: Tormentic acid in Jingulian may regulate JAK1, STAT3, and EGFR, and might play a critical role in RA/COVID-19.
RESUMO
In recent years, the frequent occurrence of smog in Chinese cities has prompted great changes in the policy environment faced by enterprises. In this study, we address the question whether the decision-making behavior of enterprises will be affected by smog. This paper studied the 2010-2018 data of 218 listed Chinese polluting companies to investigate the impact of smog on corporate social responsibility (CSR). The subjects of this study were all listed on China's A-share market on either the Shenzhen or Shanghai Stock Exchange. The empirical results indicate the following: (1) the more serious the smog, the more likely enterprises are to perform CSR; (2) smog exerts a higher impact on the social responsibility of enterprises that receive more media attention. Further research determined that media attention, whether positive, negative, or neutral, plays the same role in moderating the relationship between smog and CSR; and (3) compared to private enterprises, the function of smog in promoting the CSR fulfillment of state-owned enterprises (SOEs) is more obvious. Based on the reality of Chinese polluting industries, this research combined smog and media attention in the exploration of CSR, which not only enriches CSR research but also provides positive guidance for the sustainable development of polluting enterprises.

OBJECTIVE: To observe the clinical efficacy of Shenfu Qiangjing Decoction (SQD) in the treatment of non-inflammatory and non-liquefied semen in infertile males with kidney-yang deficiency. METHODS: Sixty cases of male infertility caused by non-inflammatory and non-liquefied semen with kidney-yang deficiency were equally and randomly divided into an SQD and a control group, the former given oral SQD and the latter vitamin C tablets plus intramuscular chymotrypsin. Both groups were observed for sperm viability, sperm motility, serum testosterone, seminal plasma PSA and improvement of kidney-yang deficiency symptoms before and after the medication. The therapeutic effects were evaluated according to the semen liquefaction within 60 min. RESULTS: Statistically significant differences were observed in the improvement of kidney-yang deficiency symptoms after the medication between the SQD and control groups (P < 0.01, P < 0.05) , and in sperm viability and motility of the SQD group before and after the treatment (P < 0.01) as well as between the two groups after the medication (P < 0.05). The levels of serum T and seminal plasma PSA also showed significant differences before and after the treatment in the SQD group (P < 0.01) and between the two groups after the medication (P < 0.05). The rate of total effectiveness was 93.3% in the SQD and 76.7% in the control group (P < 0.05). CONCLUSION: SQD can shorten the semen liquefaction time in patients with non-inflammatory and non-liquefied semen and restore semen liquefaction to normal in over 90% of the patients. Meanwhile it can also improve the low testosterone level resulting from various kidney-yang deficiency symptoms.
