BackgroundTelemedicine has been used widely in China and has benefited a large number of patients, but little is known about the overall development of telemedicine. ObjectiveThe aim of this study was to perform a national survey to identify the overall implementation and application of telemedicine in Chinese tertiary hospitals and provide a scientific basis for the successful expansion of telemedicine in the future. MethodsThe method of probability proportionate to size sampling was adopted to collect data from 161 tertiary hospitals in 29 provinces, autonomous regions, and municipalities. Charts and statistical tests were applied to compare the development of telemedicine, including management, network, data storage, software and hardware equipment, and application of telemedicine. Ordinal logistic regression was used to analyze the relationship between these factors and telemedicine service effect. ResultsApproximately 93.8% (151/161) of the tertiary hospitals carried out telemedicine services in business-to-business mode. The most widely used type of telemedicine network was the virtual private network with a usage rate of 55.3% (89/161). Only a few tertiary hospitals did not establish data security and cybersecurity measures. Of the 161 hospitals that took part in the survey, 100 (62.1%) conducted remote videoconferencing supported by hardware instead of software. The top 5 telemedicine services implemented in the hospitals were teleconsultation, remote education, telediagnosis of medical images, tele-electrocardiography, and telepathology, with coverage rates of 86.3% (139/161), 57.1% (92/161), 49.7% (80/161), 37.9% (61/161), and 33.5% (54/161), respectively. The average annual service volume of teleconsultation reached 714 cases per hospital. Teleconsultation and telediagnosis were the core charging services. Multivariate analysis indicated that the adoption of direct-to-consumer mode (P=.003), support from scientific research funds (P=.01), charging for services (P

BackgroundThe internet has caused the explosive growth of medical information and has greatly improved the availability of medical knowledge. This makes the internet one of the main ways for residents to obtain medical information and knowledge before seeking medical treatment. However, little has been researched on how the internet affects medical decisions. ObjectiveThe purpose of this study was to explore the associations between internet behaviors and medical decisions among Chinese adults aged 18 or over, including whether to go to the hospital and which level of medical institution to choose. MethodsWith the adult residents (≥18 years old) in 12 regions including urban and rural areas taken as the research objects, the differences in medical choices of adults with various characteristics were analyzed, and generalized linear mixed models were adopted to analyze the longitudinal data of the China Health Nutrition Survey from 2006 to 2015. ResultsAdult groups with different ages, genders, education levels, regions, places of residence, severities of illness and injury, years of suffering from hypertension, and history of chronic diseases showed diverse medical decisions, and the differences were statistically significant (P

In this paper, the solid solution and precipitation behavior of inclusions on the surface and 1/2 thickness of the tested steel plate under the condition of welding heat input of 400 kJ/cm is investigated by using laser confocal experiments with hot-rolled state DH36 ship plate steel as the research object, and the mechanism of the effect of inclusions on the phase transformation of an acicular ferrite is revealed. The results show that the inclusions of the tested steel are mainly composed of Oxide-MnS, MnS, Oxide, TiN, Spinel, etc. The amount of inclusions on the surface of the tested steel plate is significantly higher than that at the 1/2 thickness position. During the heating stage, the small inclusions on the surface immediately disappeared, and the large inclusions gradually solidified in the matrix; atomic diffusion occurred at the bond between the inclusions and the matrix; while the small inclusions at the 1/2 thickness position gradually disappeared at the beginning of the heating stage, and the inclusions began to precipitate and grow when the temperature was increased to 990 °C. The acicular ferrite preferentially nucleates and grows near the boundary of the inclusions during the post-weld cooling stage, and its growth ends when two acicular ferrites cross.

Background: Telemedicine is beneficial for improving treatment efficiency and reducing medical expenses of cancer patients. This study focuses on cancer patients participating in teleconsultations through a regional telemedicine platform in China, analyzes the consultation process, and provides references for the clinical application of telemedicine. Methods: We collected information on teleconsultations of cancer patients conducted from 2015 to 2022 through the regional telemedicine platform. Utilizing SPSS 23.0 software, we conducted descriptive analysis to summarize the distribution of patient gender, age, region, and disease types. The ordinal logistic regression analysis was adopted to analyze the factors influencing the waiting time and consultation duration for teleconsultations. Results: From 2015 to 2022, a total of 23,060 teleconsultations were conducted for cancer patients via regional telemedicine platform, with an average growth rate of 11.09%. The main types of consultations were for lung cancer, liver cancer, and breast cancer, accounting for 18.14%, 10.49%, and 9.46% respectively. 57.05% of teleconsultations had a waiting time of less than 24 h, while patient age, consultation expert level, and disease type were the main factors influencing the waiting time. 50.06% of teleconsultations had a duration of more than 20 min, and the inviting hospital level and the title of invited consultant were the main factors influencing the consultation duration. Conclusions: In China, telemedicine has been widely employed in the clinical diagnosis and treatment of cancers, covering various types of oncological diseases. However, the waiting time for teleconsultations was generally more than 12 h, indicating the need to enhance consultation scheduling and allocate more expert resources to further optimize the efficiency of teleconsultations. Additionally, further exploration is required for remote health management of outpatients with cancers outside the hospital. [ABSTRACT FROM AUTHOR]

To investigate the effects of different pasteurization processes (85 °C for 20 min and 75 °C for 30 min) on the edible quality and shelf life of white cut chicken, the samples were stored at 0~4 °C for 0-30-40 d, and the pH, color, texture, volatile flavor substances, volatile salt base nitrogen (TVB-N), total number of colonies, and sensory quality were determined. Results indicated that the pH value of white cut chicken treated by pasteurization process was stable, the total colony count was lower, and the generation of TVB-N was lower. After comparing with the control group, neither of the two groups of different treatments of the pasteurization process would have a significant trending effect on the eating characteristics of white cut chicken such as color, hardness and chewiness, and the sensory scores were not significantly different from those of the control group (P>0.05). Meanwhile, this study compared the relative superiority of two different pasteurization processes and demonstrated that the process condition of 85 °C pasteurization treatment for 20 min had a significant effect on inhibiting microbial growth in the product, prolonging the shelf-life of the white cut chicken, and reducing the deterioration of the edible quality of the chicken meat during storage.

To analyze the changes of spoilage bacteria on the carcasses of broiler during the slaughtering of yellow feather broiler, the diversity of spoilage bacteria in the processing environment and on the carcass surface during the efficient slaughter of yellow feather broiler was determined by the plate pouring method and Illumina MiSeq high-throughput sequencing. The results showed that the main contamination procedure for the growth of bacteria of yellow feather broilers was eviscerating, pre-cooling and grading procedure, and the grading scale, in which the grading scale, workers' gloves from grading workshop, pre-cooling tank and workers' gloves from eviscerating manual gloves were contamination sources in the three processes aforementioned. Moreover, grading scale and workers' gloves in the decomposition workshop were the main source of contaminated flora of yellow feather broilers carcasses. The growth rate of total viable counts (TVC) and Pseudomonas on the surface of yellow feather broilers carcasses was as high as 24.13% and 41.27%, respectively. The TVC of yellow feather broilers increased to 4.63 lg(CFU/g) after grading scale and grading workshop worker's hands (P<0.05). Streptococcus, Escherichia and Aeromonas were the main dominant bacteria in yellow feather broilers carcasses after plucking (DM), evisceration (JH) and disinfection (CH). The abundance of Aeromonas increased substantially in yellow feather broilers after pre-cooling, followed by Streptococcus. After the grading scale, Acinetobacter was the dominant bacterium in the yellow feather broilers carcasses, followed by Macrococcus. As the abundance of Aeromonas and Streptococcus decreased significantly on the carcasses of yellow feather broilers treated with slightly acidic electrolyzed water (SAEW), it indicated that the disinfecting effect of SAEW was obvious. The results of the present investigation could provide data support and theoretical reference for environmental control, product quality maintenance and shelf-life extension in yellow feather broilers slaughterhouse by analyzing the microbial distribution during the slaughter of yellow feather broilers.

Northern China has been identified as an independent centre of domestication for various types of millet and other plant species, but tracing the earliest evidence for the exploitation of wild cereals and thus the actual domestication process has proven challenging. Evidence from microscopic analyses of stone tools, including use-wear, starch and phytolith analyses, however, show that in the Shizitan region of north China, various plants have been exploited as far back as 28 000years ago, and wild millets have been harvested and processed by the time of the Last Glacial Maximum, 24 000 years ago. This is some 18 000-14 000 years before the earliest evidence for domesticated millet in this region. Keywords: China, Palaeolithic, Last Glacial Maximum, plant collecting, Job's tears, haematite millet, use-wear, starch grains, phytoliths, Introduction North China was a major centre of independent plant domestication, primarily for foxtail millet (Setaria italico) and broomcorn millet (Panicum miliaceum). The wild progenitor of foxtail millet is green [...]

In this paper, BLDA technology has been applied to realize the preparation of a LTPS TFT without ion implantation. The BLDA LTPS TFT gives the advantages of high mobility (~ 290.5 cm2/Vs), a smaller subthreshold voltage swing, kink‐free output curve, and excellent device stability under PBTS. The backplane technology has been successfully applied in 7.1‐inch Mini‐LED display products, and the lighting effect is uniform. This low‐cost technique is very suitable for the LTPS TFT backplane for large area, high resolution Mini/Micro LED displays. [ABSTRACT FROM AUTHOR]
