Glucose metabolic reprogramming is important in promoting the occurrence and development of malignant tumors and meeting the high demands of the malignant proliferation of tumor cells. An in-depth investigation of the mechanism of glucose metabolic reprogramming in lung cancer is important for the development of effective therapeutic strategies for lung cancer. Traditional Chinese medicine (TCM) is characterized by multiple components, targets, and pathways and can exert antitumor effects through multiple mechanisms. This article illustrates systematically the mechanism of action of Chinese herbal monomers and compound formulas regulating glucose metabolic reprogramming in lung cancer and explores deeply their regulatory effects on key enzymes of glycolysis and metabolism-related signaling pathways, and their potential in overcoming the drug resistance of lung cancer. It aims to provide a reference basis for the study of therapeutic targets and mechanisms of action of TCM in prevention and treatment of lung cancer and theoretical sources for the research and development of new medicines.

With reference to the Information and Documentation-Resource Description (GB/T 3792-2021) and Bibliographical Description for Ancient Chinese Books (GB/T 3792.7-2008) and other cataloging standards and rules, drawing on the practical experience of cataloging ancient TCM books, Bibliographical Cataloging for Ancient TCM Books was formulated. This standard specifies the entry items and their order of ancient TCM books, cataloging identifier, cataloging text, cataloging information source, and cataloging item details. The standard can provide standardized and unified guiding principles and methods for the work of ancient TCM books, and promote the sharing and utilization of ancient TCM books.

Objective:To develop and evaluate metal artifact removal systems (MARSs) based on deep learning to assess their effectiveness in removing artifacts caused by different thicknesses of metals in cone-beam CT (CBCT) images.Methods:A full-mouth standard model (60 mm×75 mm×110 mm) was three-dimensional (3D) printed using photosensitive resin. The model included a removable and replaceable target tooth position where cobalt-chromium alloy crowns with varying thicknesses were inserted to generate matched CBCT images. The artifacts resulting from cobalt-chromium alloys with different thicknesses were evaluated using the structural similarity index measure (SSIM) and peak signal-to-noise ratio (PSNR). CNN-MARS and U-net-MARS were developed using a convolutional neural network and U-net architecture, respectively. The effectiveness of both MARSs were assessed through visualization and by measuring SSIM and PSNR values. The SSIM and PSNR values were statistically analyzed using one-way analysis of variance (α=0.05).Results:Significant differences were observed in the range of artifacts produced by different thicknesses of cobalt-chromium alloys (all P<0.05), with 1 mm resulting in the least artifacts. The SSIM values for specimens with thicknesses of 1.0 mm, 1.5 mm, and 2.0 mm were 0.916±0.019, 0.873±0.010, and 0.833±0.010, respectively ( F=447.89, P<0.001). The corresponding PSNR values were 20.834±1.176, 17.002±0.427, and 14.673±0.429, respectively ( F=796.51, P<0.001). After applying CNN-MARS and U-net-MARS to artifact removal, the SSIM and PSNR values significantly increased for images with the same thickness of metal (both P<0.05). When using the CNN-MARS for artifact removal, the SSIM values for 1.0, 1.5 and 2.0 mm were 0.938±0.023, 0.930±0.029, and 0.928±0.020 ( F=2.22, P=0.112), while the PSNR values were 30.938±1.495, 30.578±2.154 and 30.553±2.355 ( F=0.54, P=0.585). When using the U-net-MARS for artifact removal, the SSIM values for 1.0, 1.5 and 2.0 mm were 0.930±0.024, 0.932±0.017 and 0.930±0.012 ( F=0.24, P=0.788), and the PSNR values were 30.291±0.934, 30.351±1.002 and 30.271±1.143 ( F=0.07, P=0.929). No significant differences were found in SSIM and PSNR values after artifact removal using CNN-MARS and U-net-MARS for different thicknesses of cobalt-chromium alloys (all P>0.05). Visualization demonstrated a high degree of similarity between the images before and after artifact removal using both MARSs. However, CNN-MARS displayed clearer metal edges and preserved more tissue details when compared with U-net-MARS. Conclusions:Both the CNN-MARS and U-net-MARS models developed in this study effectively remove the metal artifacts and enhance the image quality. CNN-MARS exhibited an advantage in restoring tissue structure information around the artifacts compared to U-net-MARS.

Background: Thyroid diseases are highly prevalent worldwide, but their diagnosis remains a challenge. We established reference intervals (RIs) for thyroid-associated hormones and evaluated the prevalence of thyroid diseases in China. Methods: After excluding outliers based on the results of ultrasound screening, thyroid antibody tests, and the Tukey method, the medical records of 20,303 euthyroid adults, who visited the Department of Health Care at Peking Union Medical College Hospital from January 2014 to December 2018, were analyzed. Thyroid-associated hormones were measured by the Siemens Advia Centaur XP analyzer. The RIs for thyroid-associated hormones were calculated according to the CLSI C28-A3 guidelines, and were compared with the RIs provided by Siemens. The prevalence of thyroid diseases over the five years was evaluated and compared using the chi-square test. Results: The RIs for thyroid stimulating hormone (TSH), free thyroxine (FT4), free triiodothyronine (FT3), total thyroxine (TT4), and total triiodothyronine (TT3) were 0.71–4.92 mIU/L, 12.2–20.1 pmol/L, 3.9–6.0 pmol/L, 65.6–135.1 nmol/L, and 1.2–2.2 nmol/L, respectively. The RIs of all hormones except TT4 differed significantly between males and females. The RIs of TSH increased with increasing age. The prevalence of overt hypothyroidism, overt hyperthyroidism, subclinical hypothyroidism, and subclinical hyperthyroidism was 0.5% and 0.8%, 0.2% and 0.6%, 3.8% and 6.1%, and 3.3% and 4.7% in males and females, respectively, which differed from those provided by Siemens. Conclusions Sex-specific RIs were established for thyroid-associated hormones, and the prevalence of thyroid diseases was determined in the Chinese population.

Objective : To construct an appropriate technology catalogue for general practice based on Delphi method,and to provide reference for promoting appropriate techniques and training general practitioners. Methods : The catalogue was briefly constructed based on literature reviews and the data of the top twenty diseases diagnosed in out-patient department of Sir Run Run Shaw Hospital and two community health service centers in Hangzhou. Two-round Delphi consultation was conducted by fourteen general practitioners coming from upper first-class hospitals and community hospitals. The final catalogue was established according to evaluation of the degree of involvement,authority coefficient and Kendall's W values of the fourteen specialists. consultations : Results Of the fourteen specialists,nine had bachelor's degrees and five had master's degrees or above;twelve were deputy chief physicians or chief physicians and two were physicians. They were engaged in general practice for 17.21 years in average. The positive coefficients of the two rounds of were both 100.00%. The authority coefficient of the specialists was 0.891. After the first round of consultation,the W values for importance and feasibility of 6 first-class indicators were 0.170 and 0.244,and the ones of 56 second-class indicators were 0.236 and 0.250（all P<0.05）. Six of second-class indicators were excluded because their coefficent of variation（CV）for importance and feasibility were more than 0.25. After the second round of consultation,the W values for importance and feasibility of 6 first-class indicators were 0.245 and 0.247,and the ones of 50 second-class indicators were 0.355 and 0.370（all P<0.05）. The CV for each indicator was less than 0.25. Finally,an instructional catalogue was defined,consisting of 6 first-class indicators（basic diagnosis and treatment skills,first aid skills,symptomatic diagnosis and treatment skills,chronic disease management skills,common disease diagnosis and treatment skills,and common manipulative skills）and 50 second-class indicators. Conclusion The degrees of involvement,authority and consistency of the specialists were relatively high. The catalogue of appropriate technology for general practitice had good reliability and feasibility,which was worthy of promotion and application.

Objective: To evaluate the disinfection efficacy of peracetic acid disinfectant (type Ⅲ ) on gastrointestinal endoscopy. Methods: Endoscopes were disinfected respectively by 2% glutaraldehyde (GA group) and peracetic acid disinfectant (type Ⅲ ) (PAA group) according to the process by the 2016 version of "Regulation for cleaning and disinfection technique of flexible endoscope" , and then samples were collected through biopsy channel at the specified steps. The bacterial count and pathogenic bacteria of these samples were detected. Hepatitis B virus surface antigen (HBsAg), hepatitis C virus (HCV) antibody and Treponemia pallidum antibody (TP-Ab) were detected by chemiluminesent microparticle immunoassay (CMIA) in the PAA group. The PAA group were continuously sampled for 5 days. Results: A total of 56 gastroscopes and 16 colonoscopes were disinfected in the GA group, and 46 gastroscopes and 15 colonoscopes were disinfected in the PAA group. Compared with pre-disinfection, the bacterial count was both significantly reduced in the two groups after disinfection (P<0.05). The qualified rate of gastroscopes disinfection and total qualified rate of the PAA group were higher than those of the GA group [the qualified rate of gastroscopes: 97.83% (45/46) VS 92.86% (52/56), P>0.05; total qualified rate: 98.36% (60/61) VS 94.44% (68/72), P>0.05]. The qualified rate of colonoscopes in the two groups were both 100.00% (15/15, 16/16). After disinfecting by peracetic acid disinfectant (Type Ⅲ), HBsAg, anti-HCV and TP-Ab were negative. There were no significant differences on colonies number at different steps in a 5-day continuous sampling (P>0.05). Conclusion Peracetic acid disinfectant (type Ⅲ) can provide a satisfied disinfectant effect, and be applied in clinic to meet the requests of high-level disinfection for gastrointestinal endoscopy.

Objective Acute aortic dissection occurs when a tear in the inside of the aorta causes blood to flow between the layers of the wall of the aorta,forcing the layers apart.In most cases this is associated with a sudden onset of severe chest or back pain,often described as "tearing" in character.The main management includes medication,endovascular repair and surgery.Medical management plays an very important role in the management of acute aortic dissection.Aortic dissection generally presents as a hypertensive emergency.Individuals can benefit from blood pressure control and anti-impulse therapy in perioperative period.
