HCWs are a priority group for vaccination because they are at increased risk of being infected, however, a certain amount of HCWs were hesitant.

Multi-wavelength excited triplet-triplet upconversion microcrystals based on hot-band excitation for optical information encryption.

Multi-wavelength hot-band excitation, forbidden in the conventional Stokes fluorescence mechanism, is found to be available with cascading triplet-triplet annihilation upconversion (TTA-UC). Selective excitation of Pt(II)octaethylporphyrin (PtOEP) by diode lasers with wavelengths of 532 nm, 589 nm, 635 nm, 655 nm, and 671 nm respectively can all induce 9,10-diphenylanthracene (DPA) to emit blue upconversion, with the maximum anti-Stokes shift of 0.95 eV in the microcrystals exposed to air.

Psychometric validation of a chinese version of COVID-19 vaccine hesitancy scale: a cross-sectional study.

Background: COVID-19 vaccines have been administered in many countries; however, a sufficient vaccine coverage rate is not guaranteed due to vaccine hesitancy. To improve the uptake rate of COVID-19 vaccine, it is essential to evaluate the rate of vaccine hesitancy and explore relevant factors in different populations. An urgent need is to measure COVID-19 vaccine hesitancy among different population groups, hence a validated scale for measuring COVID-19 vaccine hesitancy is necessary.

An Internet-Based Education Program for Human Papillomavirus Vaccination Among Female College Students in Mainland China: Application of the Information-Motivation-Behavioral Skills Model in a Cluster Randomized Trial.

Background: Patients diagnosed with cervical cancer in the last 2 decades were mainly young females.

However, most female college students in mainland China have not yet been vaccinated, and their relevant knowledge is limited.

Utilization of genetic biomarkers testing and its associated factors in advanced colorectal cancer patients in China: a nationwide multicenter clinical epidemiological study.

Background: Biomarkers are a key tool in early detection, prognostication, survival, and predicting treatment response of colorectal cancer (CRC). However, little is known about biomarker testing for CRC patients in real-life clinical practice in China. This study aimed to address the usage of biomarker testing and analyze factors related to its acceptance among Chinese patients with advanced CRC.

Out-of-pocket medical expenditure and associated factors of advanced colorectal cancer in China: a multi-center cross-sectional study.

Background: Colorectal cancer (CRC) causes a substantial disease burden in China. Information on the medical expenditure of CRC patients is critical for decision-makers to allocate medical resources reasonably, however, relevant data is limited in China, especially advanced CRC. The aim of this survey was to quantify the out-of-pocket medical expenditure of advanced CRC and explore associated factors.

The choice of medical facility and associated factors among Chinese advanced colorectal cancer patients: a cross-sectional multi-center study.

Background: Colorectal cancer (CRC) poses a significant public health burden worldwide. The investigation of the choice of medical facility among CRC patients is helpful for understanding access to health services and improving quality of oncology services to optimize health outcomes. However, there are limited studies on the topic.

Health-related quality of life in advanced colorectal cancer patients in China: a nationwide hospital-based survey.

Background: Colorectal cancer (CRC) is one of the most common cancers in China, and most CRC patients have already reached an advanced stage by the time of initial diagnosis. Due to the loss of health as a result of cancer, it has consequence on the treatment which may affect the psychophysical and social impairment of CRC patients. These indicators (psychophysical, function and social impairment) affect the health-related quality of life (HRQOL).

Status and associated factors of cross-regional healthcare-seeking among patients with advanced colorectal cancer in China: a multicenter cross-sectional study.

Background: The imbalanced allocation of medical resources leads to the occurrence of cross-regional healthcare-seeking in China. Due to the low cure rate, advanced colorectal cancer (CRC) patients may seek cross-regional healthcare for high-level medical facilities. Investigating status of cross-regional healthcare-seeking and its associated factors among advanced CRC patients is important for policymakers to understand access to health services and improve the quality of oncology services.

[Mental Health Status and Its Influencing Factors among College Students during the Epidemic of Coronavirus Disease 2019:A Multi-center Cross-sectional Study].

Objective To measure the prevalence of mental health symptoms and identify the associated factors among college students at the beginning of coronavirus disease 2019(COVID-19)outbreak in China. Methods We carried out a multi-center cross-sectional study via snowball sampling and convenience sampling of the college students in different areas of China.The rates of self-reported depression,anxiety,and stress and post-traumatic stress disorder(PTSD)were assessed via the 21-item Depression-Anxiety-Stress Scale(DASS-21)and the 6-item Impact of Event Scale-Revised(IES-6),respectively.

COVID-19 vaccine hesitancy among different population groups in China: a national multicenter online survey.

Background: COVID-19 vaccine has been available in China since the beginning of the 2021, however, certain numbers of people are reluctant for some reasons to vaccinate.
