With the development of the new medical science, the traditional traditional education mode of morphology is facing to weakness and challenges. Under the guidance of learning by doing, we constructed a 3D model workshop as an innovative teaching platform. The questionnaire investigation showed that students were approved by the learning mode of 3D model workshop, which was helpful to improve students capacity building in terms of skill and exploration.

The global monkeypox outbreak in 2022 has severely affected the life and health of people. Currently, partial smallpox vaccines have been approved for monkeypox prevention. Considering the potential occupational health risks of monkeypox infection among healthcare workers (HCWs), this study explored the willingness of Chinese HCWs to receive the monkeypox vaccine and analyzed the factors influencing their decision. We conducted an online cross‐sectional survey among HCWs of 10 Chinese hospitals from May 30th, 2022 to August 1st, 2022. Specifically, a self‐report questionnaire was administered to evaluate the attitude and acceptance of HCWs toward the monkeypox vaccine, followed by a multivariate logistic regression analysis to determine the independent predictors of vaccination. The survey included 1032 participants, of whom 90.12% expressed their willingness for vaccination (vaccine hesitancy rate = 9.88%). Univariate analysis showed that 11 variables differed significantly between the vaccine acceptance and vaccine hesitancy groups. Multivariate logistic regression analysis demonstrated that the age of 30–40 years (odds ratio [OR] = 0.504, 95% confidence interval [CI]: 0.284–0.893, p = 0.019 vs. age of <30 years old), working in a secondary hospital (OR = 0.449, 95% CI: 0.249–0.808, p = 0.019 vs. working in a tertiary hospital), considering vaccination necessary for controlling monkeypox infection (OR = 4.135, 95% CI: 2.109–8.106, p < 0.001 vs. not considering it necessary), willingness to pay for the monkeypox vaccine (OR = 2.125, 95% CI: 1.206–3.745, p = 0.009 vs. no willingness to pay), considering implementation of mandatory vaccination necessary (OR = 1.990, 95% CI: 1.023–3.869, p = 0.043 vs. not considering it necessary), and recommending family members and friends to take the vaccine (OR = 13.847, 95% CI: 7.487–25.609, p < 0.001 vs. not recommending) were crucial independent predictors of the willingness to receive monkeypox‐related vaccination. This study evaluated the acceptance and hesitancy rates of Chinese HCWs toward the monkeypox vaccine and found that the willingness to receive vaccination was mainly correlated to age, hospital level, and attitude toward vaccination. Therefore, to promote vaccine absorption, we recommend expanding publicity, formulating reasonable policies, and improving the recognition of vaccines. [ABSTRACT FROM AUTHOR]

Objective: To explore the mechanism of chromobox 7 (CBX7)-mediated nuclear factor E2-related factor 2 (Nrf2)/hemeoxygenase-1 (HO-1) signaling pathway in the cerebral ischemia/reperfusion (I/R) injury. Methods: The experimental wild-type (WT) and CBX7-/- mice were used to establish cerebral I/R models using the middle cerebral artery occlusion (MCAO) surgery to determine CBX7 levels at different time points after MCAO injury. For all mice, neurological behavior, infarct size, water content, and oxidative stress–related indicators were determined, and transferase (TdT)-mediated dUTP-biotin nick-end labeling (terminal deoxynucleotidyl transferase (TdT)-mediated dUTP nick-end labeling (TUNEL)) staining method was employed to observe cell apoptosis, while Western blot to measure the expression of CBX7 and Nrf/HO-1 pathway-related proteins. Results: At 6 h, 12 h, 24 h, 3 days, and 7 days after mice with MCAO, CBX7 expression was gradually up-regulated and the peak level was reached at 24 h. Mice in the WT + MCAO group had increased infarct size, with significant increases in the modified neurological severity scores and water content in the brain, as well as the quantity of TUNEL-positive cells. For the oxidative stress-indicators, an increase was seen in the content of MDA (malondial dehyde), but the activity of SOD (superoxide dismutase) and content of GSH-PX (glutathione peroxidase) and CAT (catalase) were decreased; meanwhile, the protein expression of CBX7, HO-1, and nuclear Nrf2 was up-regulated, while the cytoplasmic Nrf2 was down-regulated. Moreover, CBX7 knockout attenuated I/R injury in mice. Conclusion: Knockout of CBX7 may protect mice from cerebral I/R injury by reducing cell apoptosis and oxidative stress, possibly via activating the Nrf2/HO-1 pathway. [ABSTRACT FROM AUTHOR]

Abstract: It remains a great challenge to design and synthesize a porous material for CO2 capture and sensing simultaneously. Herein, strategy of “cage to frameworks” is demonstrated to synthesize fluorescent porous organic polymer (pTOC) by using tetraphenylethylene‐based oxacalixarene cage (TOC) as the monomer. The networked cages (pTOC) have improved porous properties, including Brunauer–Emmett–Teller surface area and CO2 capture compared with its monomer TOC, because the polymerization overcomes the window‐to‐arene packing modes of cages and turns on their pores. Moreover, pTOC displays prominent reversible fluorescence enhancement in the presence of CO2 in different dispersion systems and fluorescence recovery for CO2 release in the presence of NH3·H2O, and is thus very effective to detect and quantify the fractions of CO2 in a gaseous mixtures.

This study aimed to investigate the knowledge about, attitudes toward, and acceptance and predictors of receiving the mpox vaccine among Chinese cancer patients. Patients were selected using a convenience sampling method. A web-based self-report questionnaire was developed to assess cancer patients' knowledge, attitudes, and acceptance regarding the mpox vaccine. Multivariate logistic regression analysis was used to determine predictors of acceptance of the mpox vaccine. A total of 805 cancer patients were included in this study, with a vaccine hesitancy rate of 27.08%. Approximately 66% of the patients' information about mpox and the vaccine came from the mass media, and there was a significant bias in the hesitant group's knowledge about mpox and the vaccine. Multivariable logistic regression analysis suggested that retirement; chemotherapy; the belief that the mpox vaccine could prevent disease, that vaccination should be compulsory when appropriate and that the mpox vaccine prevents mpox and reduces complications; the willingness to pay for the mpox vaccine; the willingness to recommend that friends and family receive the mpox vaccine; and the belief that the mpox vaccine should be distributed fairly and equitably were factors that promoted vaccination. The belief that mpox worsens tumor prognosis was a driving factor for vaccine hesitancy. This study investigated the knowledge of cancer patients about mpox and the vaccine, evaluated the acceptance and hesitancy rates of the mpox vaccine and examined the predictors of vaccination intention. We suggest that the government scientifically promote the vaccine and develop policies such as free vaccination and personalized vaccination to increase the awareness and acceptance rate of the mpox vaccine.

Continuous sampling using the tank sampling method were conducted in Changsha, Zhuzhou, and Xiangtan cities from August 18 to 27, 2020, and 106 VOCs species were analyzed using GC-MS analysis. Then, the regional VOCs concentrations, generation potential, and source of VOCs were studied. The results showed that the average φ (VOCs) was (20.5±10.5)×10 -9 in the Changsha-Zhuzhou-Xiangtan area, in which OVOCs (33.5%) and alkanes (28.2%) accounted for the highest proportion. The ozone formation potential (OFP) of VOCs was 118.5 μg·m -3 , and the contributions of aromatic hydrocarbons, olefin, and OVOCs to OFP were 37.4%, 24.2%, and 23.6%, respectively. The average secondary organic aerosol formation potential (SOA p ) of the VOCs was 0.5 μg·m -3 , and the contribution of aromatic hydrocarbons to SOA p was 97.0%, among which C8 aromatic hydrocarbons contributed 41.7%. Toluene, m/p -xylene, and o -xylene were the common dominant species that contributed significantly to OFP and SOA p . The characteristic ratio results showed that VOCs in Changsha were relatively influenced by industrial processes and solvent use, whereas Zhuzhou and Xiangtan were more affected by coal and biomass combustion. The PMF results showed that the VOCs mainly came from vehicle exhaust and oil and gas volatilization (27.2%), coal and biomass combustion (23.7%), industrial processes (20.4%), solvent use (17.2%), and natural sources (11.5%) in the Changsha-Zhuzhou-Xiangtan area.

Objective: To evaluate the efficacy of combined epigenetic drugs of decitabine (DAC), valproic acid (VPA) and trichostatin A (TSA) on immunotherapy with a murine model of hepatocellular carcinoma (HCC)., Methods: Dendritic cells (DCs) transduced with recombinant lentivirus expressing a cancer-testis antigen, acrosin binding protein (ACRBP), are referred to as DC/ACRBP. CD8 + T cells were harvested from spleens of C57BL/6 mice and activated by DC/ACRBP. Cytotoxicity of DC/ACRBP-activated T cells was analyzed by cytotoxicity and murine xenograft assays., Results: Cytotoxicity assay results revealed that DC/ACRBP-activated T cells exhibited the highest cytotoxicity against HCC cells pre-treated with triple drugs (DAC+VPA+TSA) compared with dual drugs (DAC+VPA and DAC+TSA) and single drug (DAC, VPA and TSA) respectively. Analyses of RT-PCR and immunoblotting demonstrated that the highest ACRBP expression of HCC cells was induced by the triple drugs compared with the single and dual drugs. These results indicated that DC/ACRBP-activated T cells might be ACRBP-specific lymphocytes, and the augmented cytotoxicity may be dependent on the upregulation of ACRBP expression. These assumptions were further confirmed by xenograft tumor assay. Tumor cells of mice administrated with the triple drugs exhibited increased ACRBP expression compared with those of mice without administration. As expected, DC/ACRBP-activated T cells adopted by mice injected with the triple drugs, compared with those adopted by mice without injection, remarkably impeded growth and facilitated apoptosis of tumor cells., Conclusion: These data suggested that combined treatment with DAC, VPA and TSA may enhance the anti-tumor efficacy of ACRBP-specific T cells by upregulating ACRBP expression in HCC., Competing Interests: None., (AJTR Copyright © 2021.)

Based on the best available activity data and emission factors, an anthropogenic emission inventory of NH3 was established for the Chang-Zhu-Tan region with spatial resolution of 3 km x 3 km. The results showed that the total quantity of NH3 discharged from anthropogenic sources in the Chang-Zhu-Tan region was 7.27 x 10(4) t, and the average intensity of NH3 emission was 2. 59 t x km(-2). The livestock and poultry industry, and the farmland ecosystem, were the major contribution sources of the anthropogenic NH3 emissions, accounting for 58. 60% and 29.73%, respectively. As for NH3 emission from the livestock and poultry industry, the major contributors were beef, laying hen and pork pig, accounting for 26.26%, 21.40% and 18.43%, respectively. In the Chang-Zhu-Tan region, the quantities of NH3 emissions from Ningxiang county, Xiangtan county and Liuyang city were larger than those of the other districts, accounting for 17. 49%, 12. 82% and 12.02%, respectively. The intensities of NH3 emission from Shifeng and Yuetang districts were larger than those from other districts, reaching up to 9.14 t x km(-2) and 5.01 t x km(-2), respectively. The spatial distribution characteristics revealed that the NH3 emission mostly originated from large point sources.

Cancer/testis (CT) antigens are normally expressed in testis and overexpressed in various tumor types. However, their biological function is largely unknown. OY-TES-1, one of cancer/testis (CT) antigens, is reported overexpression in hepatocellular carcinoma (HCC). And we assumed that OY-TES-1 contribute to oncogenesis and progression of HCC. In this study, we knocked down OY-TES-1 by small interference RNA (siRNA) in HCC cell lines (HepG2 and BEL-7404) to verify this assumption and evaluate its potential as therapeutic targets for HCC. We showed that down regulation of OY-TES-1 decreased cell growth, induced the G0/G1 arrest and apoptosis, and prevented migration and invasion in the two HCC cell lines. Further analysis revealed that down regulation of OY-TES-1 increased expression of apoptosis-regulated protein caspase-3, and decreased expression of cell cycle-regulated protein cyclin E, migration/invasion-regulated proteins MMP2 and MMP9. These findings may shed light on the gene therapy about the OY-TES-1 expression in HCC cells.
