[Clinical characteristics and outcome analysis of COVID-19 patients with pulmonary tuberculosis].

Coronavirus disease (COVID-19) and tuberculosis (TB) are two respiratory infectious diseases with a high incidence of transmission, mainly via respiratory droplets and both can weaken the immune system and lower the number of CD4+T cells in patients. COVID-19 can occur before, at the same time or after the diagnosis of TB. Patients with pulmonary TB are more likely to have co-infection when they have a history of epidemiological exposure to COVID-19. At present, many cases of nosocomial infection of COVID-19 caused by ineffective prevention and control measures in tuberculosis hospitals have been reported successively at domestic and overseas. Therefore, it is urgent to strengthen the prevention and control of nosocomial infections in tuberculosis hospitals. The superposition of the two diseases can lead to a worsening prognosis, aggravating the patient's condition and making treatment more difficult. In addition, in the context of the new coronavirus epidemic, early recognition of co-infection with new coronavirus should be made when TB patients in chest hospitals present with symptoms such as aggregated fever or progressive disease. At the same time, we should focus on identifying the clinical and imaging manifestations of TB and COVID-19 co-infection. At present, research on COVID-19 complicated with pulmonary TB is scarce, and there are disputes on many aspects. As a country with a high prevalence of tuberculosis, it is of great practical significance to identify the clinical characteristics, outcomes, and treatment of the two infectious diseases in China.

Media Exposure and Third-Person Perception: The Mediating Role of Social Realism and Proxy Efficacy

This study examines the influences of media exposure, social realism, and proxy efficacy on the perceived effects of news about the COVID-19 pandemic. Using data collected from a sample of 1,190 college students in China, this study found that exposure to news about the pandemic is positively related to social realism and proxy efficacy. Furthermore, social realism and proxy efficacy were significantly correlated with third-person perception (TPP). Most importantly, the results of the study show that social realism and proxy efficacy also mediated the relationship between exposure to COVID-19 news and TPP.

XIV Social Economic Development Plan 2021-2025: Challenges for the New Model of Economic Development of China

This article analyses the renewed economic development strategy called dual circulations in China from the points of view of the economic development theories, proposed for the XIV Social Economic Development Plan 2021-2025. The analytical methodology is carried out by two perspectives: a retrospective, which reviews the Chinese economic evolution status quo during the last 40 years, and the prospective one, that shows how the trading frictions between China and the United States and Covid-19 have reinforced and as the self-conscious, the Asia country, to adjust its economic development model and the future economic growth projections. It is hypothesized that China will achieve its economic development goals not only in the medium but in the long term through the application of the dual circulations' orientation. For this reason, the work will hope to have a contribution to the theoretical debates before the urgency for the underdeveloped nations to look for alternatives with the purpose to fulfill the desired economic development objective.

The Study of Quality Evaluation Model for the Real-Time Interactive Online Teaching

The massive-scale real-time interactive online teaching that emerged during the COVID-19 pandemic is more intangible and interactive than traditional recording and broadcasting teaching and flipped class, whose quality is more difficult to measure. At present, the epidemic around the world is not optimistic, and universities worldwide are still in the online teaching mode. Constructing a scientific multi-dimensional teaching quality evaluation system is the key to ensuring the quality of real-time interactive teaching in institutions of higher education, and mixed teaching in the post-epidemic era. This study introduces the SERVQUAL service quality measurement method, with students as the majority of evaluation, aiming to construct a real-time interactive online teaching quality evaluation model in universities. This method consists of five dimensions--Tangibles, Reliability, Responsiveness, Assurance and Empathy. Based on this model, this study conducted data analysis on the online teaching quality of universities under the epidemic situation, pointed out the content of service quality that needs to be improved in online teaching, and put forward countermeasures and suggestions for improvement.

UNCERTAINTY BASED ON VIRUS REPORTS: WHAT IS THE EFFECT OF SARS-COV-2 ON MALE REPRODUCTION? (COVID-19 AND MALE REPRODUCTION)

Background and objectives Coronavirus disease 2019 (COVID-19) has become a pandemic. Preliminary data reported that severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) might not be found in the semen of patients in the early stages of COVID-19;however, the virus may be seen in the semen in the late, severe stages. To determine the effects of SARS-CoV-2 infection on the male reproductive system. Materials and methods We reviewed the relationship between previously reported infections with mumps virus (MuV), HIV, Zika virus, hepatitis virus B, hepatitis virus C, SARS-CoV, and influenza viruses that could possibly damage the male reproductive system, and then investigated whether SARS-CoV-2 infection could cause any damage to the male reproductive system. Results There were various reports that viruses could impair male reproduction by entering into the testicular cells, inducing inflammation, or both. Regarding SARS-CoV-2, five recent independent studies showed no evidence to suggest that SARS-CoV-2 could be found in the semen and testicular tissues, suggesting that SARS-CoV-2 would not directly damage the blood-testis barrier (BTB) in the early stages of COVID-19 infection. However, a study found that viral RNA was found in 6 out of 38 patients. Three studies found that there were some changes in the sexual hormone levels. Discussion and conclusion There is a lack of substantial evidence to determine how SARS-CoV-2 affects male reproduction at this moment. Understanding of the relationship between SARS-CoV-2 and male infertility requires further research.
