By analyzing the current application of multi-modal data in the diagnosis of gastric "inflammation-cancer" transformation， this study explored the feasibility and strategies for constructing a disease-syndrome integrated diagnosis and treatment system. Based on traditional Chinese medicine （TCM） phenomics， we proposed utilizing multi-modal data from literature research， cross-sectional studies， and cohort follow-ups， combined with artificial intelligence technology， to establish a multi-dimensional diagnostic and treatment index system. This approach aims to uncover the complex pathogenesis and transformation patterns of gastric "inflammation-cancer" progression. Additionally， by dynamically collecting TCM four-diagnostic information and modern medical diagnostic information through a long-term follow-up system， we developed three major modules including information extraction， multi-modal phenotypic modeling， and information output， to make it enable real-world clinical data-driven long-term follow-up and treatment of chronic atrophic gastritis. This system can provide technical support for clinical diagnosis， treatment evaluation， and research， while also offering insights and methods for intelligent TCM diagnosis.

BACKGROUND: While emotional distress, encompassing anxiety and depression, has been associated with negative clinical outcomes, its impact across various clinical departments and general hospitals has been less explored. Previous studies with limited sample sizes have examined the effectiveness of specific treatments (e.g., antidepressants) rather than a systemic management strategy for outcome improvement in non-psychiatric inpatients. To enhance the understanding of the importance of addressing mental health care needs among non-psychiatric patients in general hospitals, this study retrospectively investigated the impacts of emotional distress and the effects of early detection and management of depression and anxiety on hospital length of stay (LOS) and rate of long LOS (LLOS, i.e., LOS >30 days) in a large sample of non-psychiatric inpatients. METHODS: This retrospective cohort study included 487,871 inpatients from 20 non-psychiatric departments of a general hospital. They were divided, according to whether they underwent a novel strategy to manage emotional distress which deployed the Huaxi Emotional Distress Index (HEI) for brief screening with grading psychological services (BS-GPS), into BS-GPS ( n = 178,883) and non-BS-GPS ( n = 308,988) cohorts. The LOS and rate of LLOS between the BS-GPS and non-BS-GPS cohorts and between subcohorts with and without clinically significant anxiety and/or depression (CSAD, i.e., HEI score ≥11 on admission to the hospital) in the BS-GPS cohort were compared using univariable analyses, multilevel analyses, and/or propensity score-matched analyses, respectively. RESULTS: The detection rate of CSAD in the BS-GPS cohort varied from 2.64% (95% confidence interval [CI]: 2.49%-2.81%) to 20.50% (95% CI: 19.43%-21.62%) across the 20 departments, with a average rate of 5.36%. Significant differences were observed in both the LOS and LLOS rates between the subcohorts with CSAD (12.7 days, 535/9590) and without CSAD (9.5 days, 3800/169,293) and between the BS-GPS (9.6 days, 4335/178,883) and non-BS-GPS (10.8 days, 11,483/308,988) cohorts. These differences remained significant after controlling for confounders using propensity score-matched comparisons. A multilevel analysis indicated that BS-GPS was negatively associated with both LOS and LLOS after controlling for sociodemographics and the departments of patient discharge and remained negatively associated with LLOS after controlling additionally for the year of patient discharge. CONCLUSION Emotional distress significantly prolonged the LOS and increased the LLOS of non-psychiatric inpatients across most departments and general hospitals. These impacts were moderated by the implementation of BS-GPS. Thus, BS-GPS has the potential as an effective, resource-saving strategy for enhancing mental health care and optimizing medical resources in general hospitals.

Advances in novel drugs, therapies, and genetic techniques have revolutionized the diagnosis and treatment of cancers, substantially improving cancer patients' prognosis. Although rare tumors account for a non-negligible number, the practice of precision medicine and development of novel therapies are largely hampered by many obstacles. Their low incidence and drastic regional disparities result in the difficulty of informative evidence-based diagnosis and subtyping. Sample exhaustion due to difficulty in diagnosis also leads to a lack of recommended therapeutic strategies in clinical guidelines, insufficient biomarkers for prognosis/efficacy, and inability to identify potential novel therapies in clinical trials. Herein, by reviewing the epidemiological data of Chinese solid tumors and publications defining rare tumors in other areas, we proposed a definition of rare tumor in China, including 515 tumor types with incidences of less than 2.5/100 000 per year. We also summarized the current diagnosis process, treatment recommendations, and global developmental progress of targeted drugs and immunotherapy agents on the status quo. Lastly, we pinpointed the current recommendation chance for patients with rare tumors to be involved in a clinical trial by NCCN. With this informative report, we aimed to raise awareness on the importance of rare tumor investigations and guarantee a bright future for rare tumor patients.

Objective:To study the prevalence and distribution of adult thyroid diseases in urban and rural areas of Hebei Province.Methods:A multi-stage stratified cluster sampling method was used to select Renqiu City and Licun Town, Luquan City of Hebei Province as the urban and rural survey sites, respectively. Questionnaire survey, physical examination and thyroid B ultrasound examination were conducted on local permanent residents (≥ 5 years of residencies) over 18 years old. The fasting venous blood sample was collected to determine the serum thyroid function indicaters.Results:A total of 2 650 adults were surveyed, including 1 393 urban residents and 1 257 rural residents (1 357 males and 1 293 females). A total of 435 patients with thyroid diseases were diagnosed, the detection rate was 16.42%. There were seven thyroid diseases, including subclinical hypothyroidism (60.92%, 265/435), Hashimoto's thyroiditis (34.02%, 148/435), hypothyroidism (4.83%, 21/435), simple goiter (3.22%, 14/435), hyperthyroidism (2.53%, 11/435), subclinical hyperthyroidism (2.53%, 11/435), and thyroid cancer (1.84%, 8/435). The detection rates of thyroid diseases in urban and rural areas were 21.18% (295/1 393) and 11.14% (140/1 257), respectively. The detection rates of thyroid diseases in males and females were 11.42% (155/1 357) and 21.66% (280/1 293), respectively. The detection rates of thyroid diseases in 18-< 30, 30-< 40, 40-< 50, 50-< 60 and ≥60 years old were 13.46% (91/676), 14.81% (81/547), 15.42% (89/577), 20.94% (85/406) and 20.05% (89/444), respectively. There were statistically significant differences between different areas, gender and age groups (χ 2 = 48.54, 50.53, 14.68, P < 0.05). Conclusions:The detection rate of subclinical hypothyroidism in adults in urban and rural areas of Hebei Province is relatively high, followed by Hashimoto's thyroiditis. Attention should be paid to the screening, evaluation, and intervention of thyroid function among urban female populations.

Objective:To deliver understanding of the latest research progress on clinical trials and approval of dermatological drugs in China in 2020.Methods:A registration and information disclosure platform for drug clinical studies and a query system for domestic and imported drugs in the National Medical Products Administration of China were searched for registered clinical trials and approved dermatological drugs, respectively. The number and stages of clinical trials, indications and classification of involved products, and listed dermatological drugs in 2020 were summarized and depicted.Results:There were 157 dermatological drug trials registered in China in 2020, accounting for 6.16% of all the 2 548 clinical drug trials, including 127 (80.9%) initiated by Chinese pharmaceutical enterprises and 25 (15.9%) international multicenter trials. Among the 127 drug trials initiated by Chinese pharmaceutical enterprises, bioequivalence trials were mostly common, accounting for 55.9% (71/127) . Compared with global pharmaceutical enterprises, domestic pharmaceutical companies initiated significantly decreased proportions of international multicenter trials (1.9% [3/157] vs. 14.0% [22/157], P < 0.001) , but significantly increased proportions of phaseⅠclinical trials and bioequivalence trials (24.4% [31/127] vs. 10.0% [3/30], 55.9% [71/127] vs. 0, respectively, both P < 0.001) . Totally, 90 kinds of dermatological drug were involved in all the trials, psoriasis, atopic dermatitis and melanoma were the most common indications, and innovative drugs accounted for 53.3% (48/90) ; the proportion of innovative drugs was significantly lower in domestic pharmaceutical companies than in global pharmaceutical companies (43.2% [32/74] vs. 16/16, P < 0.001) . In addition, 28 dermatological drugs developed by 22 pharmaceutical companies were approved in China in 2020, of which 21 drugs were developed by domestic pharmaceutical companies. Conclusion:Clinical drug trials carried out by domestic pharmaceutical companies mostly focus on generic drugs, and it is still necessary for domestic pharmaceutical companies to further improve the innovation ability.

Objective:To explore the feasibility of using Double FLASH coronary CTA (CCTA) to evaluate myocardial blood perfusion based on the original Patlak Plots.Methods:A total of 50 subjects with non-ischemic heart disease were prospectively included in the study who received dynamic myocardial CT perfusion (CTP) and Double FLASH CTA scans in General Hospital of Tianjin Medical University from January 2018 to January 2020 due to coronary heart disease or suspected coronary heart disease. The age of the enrolled patients was at least 18 years old and there was no moderate or above stenosis on CTA. The dynamic CTP images were analyzed by using CTP analysis software on FRONTIER platform to calculate the CTP derived MBF (MBF CTP). While the CTA derived MBF (MBF CTA) was calculated from the CT attenuation values of both aorta and myocardium segments on two scanning time set of Double FLASH CTA which were measured by two independent radiologists. Pearson correlation and Bland-Altman analysis were used to compare the results of MBF CTP and MBF CTA. Results:There was a strong linear correlation between MBF CTP and MBF CTA measurements. In the mid anteroseptal level: MBF CTA=0.936MBF CTP-11.999, r2=0.600, P<0.01. In the mid anterolateral level: MBF CTA=1.010MBF CTP-9.206, r2=0.448, P<0.01. In the apex: MBF CTA=0.822MBF CTP+16.904, r2=0.375, P<0.01. Bland-Altman analysis also showed there were no significant differences between MBF CTP and MBF CTA measurements. Compared with dynamic CTP scan, Double FLASH CTA mode significantly reduced the radiation dose [(4.33±1.89) mSv vs. (1.38±0.19) mSv, t=4.378, P=0.030]. Conclusions:This study validated the feasibility and accuracy of the MBF CTA measurement based on the theory of Patlak Plots only using Double FLASH CTA images. This method might have the potential to expand the clinical application of one-stop CTP examination for simultaneously evaluating coronary artery and myocardial ischemia in the clinic.

Objective:The existed economic evaluations of cancer screening in Chinese population are almost all single-cancer focused, evidence on parallel comparison among multiple cancers is lacking. Thus, the aim of this study was, from a priority setting perspective, to compare the cost-effectiveness of six common cancers(colorectal cancer, breast cancer, liver cancer, lung cancer, esophageal cancer and stomach cancer) to facilitate policy making in future scaled-up screening in populations in China.Methods:Partially based on our previous single-cancer systematic reviews (colorectal cancer, breast cancer, liver cancer, and lung cancer), evidence of economic evaluations of cancer screening in populations in mainland China were systematically updated and integrated. The main updates include: 1) Stomach cancer and esophageal cancer were newly added to the current analysis. 2) The literature searching was extended to 8 literature databases, including PubMed, EMbase, The Cochrane Library, Web of Science, CBM, CNKI, Wanfang Data, and VIP. 3) The period of publication year was updated to the recent 10 years: January 1, 2009 to December 31, 2018. 4) The study focused on populations in mainland China. Following the standard processes of literature searching, inclusion and exclusion from previous systematic reviews, the basic characteristics, evaluation indicators and main results of the included studies were extracted. All the costs were discounted to 2017 value using the by-year consumer price index of medical and health care residents in China and presented in the Chinese Yuan (CNY). The ratios of incremental cost-effectiveness ratio (ICER) to China′s per capita GDP in 2017 were calculated (<1 means very cost-effective, 1-3 means cost-effective, >3 means not cost-effective). Given a specific indicator, the median value among all reported screening strategies for each cancer was calculated, based on which priority ranking was then conducted among all cancers when data available.Results:A total of 45 studies were included, 22 for breast cancer, 12 for colorectal cancer, 6 for stomach cancer, 4 for esophageal cancer (all conducted in high-risk areas), 1 for liver cancer and none for lung cancer (was not then considered for next ranking due to limited numbers of studies). When based on the indicator, the median ratio of cost per life-year saved to China′s per capita GDP (reported in 12 studies), the lowest ratio (-0.015) was observed in esophageal cancer among 16 strategies of 2 studies ( N=2, n=16), followed by 0.297 for colorectal cancer ( N=3, n=12), 0.356 for stomach cancer ( N=1, n=4) and 0.896 for breast cancer ( N=6, n=52, P75=3.602). When based on another commonly used ICER indicator, the median ratio of cost per quality-adjusted life-year gained to China′s per capita GDP (reported in 13 studies), the least cost was found in stomach cancer (0.495, N=3, n=8, P75=3.126), followed by esophageal cancer (0.960, N=1, n=4, P75=1.762) and breast cancer (2.056, N=9, n=64, P75=4.217). Data was not found for colorectal cancer. In addition, cost per cancer case detected was the most adopted indicator (32 studies). The median cost among all screening strategies for each cancer was 14 759 CNY for stomach cancer ( N=5, n=7), 49 680 CNY for colorectal cancer ( N=12, n=25) and 171 930 CNY for breast cancer ( N=13, n=24), respectively. Data was not available for esophageal cancer and rare for precancer cases detected. Evidence related to cost per disability-adjusted life-year gained was not available. Conclusions:At China′s national level and limited to the six cancers covered by the current study, the preliminary analysis suggests that stomach cancer and colorectal cancer were the most cost-effective target cancers and could be given priority in the future scaled-up screening in general populations. Esophageal cancer screening should be prioritized in high-risk areas. Breast cancer was also cost-effective in general but some of the intensive screening strategies were marginal. Data on liver cancer and lung cancer were too limited to conclude, and more well-designed studies and high-quality research evidence should be required. This priority ranking might be changed if other common cancers were involved analyses.

Objective: To understand the health literacy and relevant factors of cancer prevention consciousness in Chinese urban residents from 2015 to 2017. Methods: A cross-sectional survey was conducted in 16 provinces covered by the Cancer Screening Program in Urban China from 2015 to 2017. A total of 32 257 local residents aged ≥18 years old who could understand the investigation procedure were included in the study by using the cluster sampling method and convenient sampling method. All local residents were categorized into four groups, which contained 15 524 community residents, 8 016 cancer risk assessment/screening population, 2 289 cancer patients and 6 428 occupational population, respectively. The self-designed questionnaire was used to collect the information of demographic characteristics and cancer prevention consciousness focusing on nine common risk factors, including smoking, alcohol, fiber food, food in hot temperature or pickled food, chewing betel nut, helicobacter pylori, moldy food, hepatitis B infection, estrogen, and exercise. The logistic regression model was adopted to identify the influencing factors. Results: The overall health literacy of the cancer prevention consciousness was 77.4% (24 980 participants), with 77.4% (12 018 participants), 79.9% (6 406 participants), 77.2% (1 766 participants) and 74.5% (4 709 participants) in each group (P<0.001). The correct response rates for nine risk factors ranged from 55.2% to 93.0%. The multivariate logistic regression analysis showed that compared with community residents, people with primary school level education or below, and the number of people living together in the family <3, the cancer risk assessment/screening intervention population, cancer patients, those with junior high school level educationor above and the number of people living in the family ≥3 had better health literacy of the cancer prevention consciousness (all P values <0.05). Compared with females, 39 years old and below, government-affiliated institutions or civil servants, from the eastern region, males, older than 40 years, company or enterprise employees, and from the middle or western region had worse health literacy of the cancer prevention consciousness (all P values <0.05). Conclusion The health literacy of the cancer prevention consciousness in Chinese urban residents should be improved. The cancer screening intervention, gender, age, education, occupation, the number of people co-living in the family, and residential region were associated with the health literacy of the cancer prevention consciousness.

Objective: To understand the consciousness of the cancer early detection among urban residents and identify the influencing factors from 2015 to 2017. Methods: A cross-sectional survey was conducted in 16 provinces covered by the Cancer Screening Program in Urban China from 2015 to 2017. A total of 32 257 local residents aged ≥18 years old who could understand the investigation procedure were included in the study by using the cluster sampling method and convenient sampling method. All local residents were categorized into four groups, which contained 15 524 community residents, 8 016 cancer risk assessment/screening population, 2 289 cancer patients and 6 428 occupational population, respectively. Self-designed questionnaires were used to collect population, socioeconomic indicators, self-cancer risk assessment, regular participation in physical examination and other information. The multivariate logistic regression model was used to identify the factors of people who had not regularly participated in the regular physical examination in the past five years. Results: The self-assessment results of 32 357 residents showed that there were 27.54% (8 882) of total study population with self-reported cancer risk, 45.48% (14 671) without cancer risk and 26.98% (8 704) with unclear judgement on their own cancer risk. Among population with cancer risk, 79.84% (7 091) considered physical examination accounted. In the past five years, there were 21 105 (65.43%) residents participated in regular physical examination and 11 148 (34.56%) participated in non-scheduled one, respectively. The multivariate logistic regression analysis showed that compared with unmarried and western region residents, divorced, middle and eastern region residents had a stronger consciousness to participate in the regular physical examination (P<0.05). Compare with residents with annual household income less than 20 000 CNY in 2014, cancer risk assessment/screening intervention population, and self-assessment with cancer risk, residents with annual household income between 20 000 CNY and 59 000 CNY in 2014, occupational population, community residents, cancer patients, self-reported cancer-free risk, and self-assessment with unclear judgement of cancer risk were less likely to participate in the regular physical examination (all P values <0.05). Conclusion From 2015 to 2017, the Chinese urban residents had a acceptable consciousness of the cancer early detection. The marital status, annual household income, population group and self-assessment of cancer risk were related to the consciousness of the cancer early detection of people who had not participated in the regular physical examination in the past five years.
