Objective To investigate the relationship and mechanism of the serum vitamin D levels with insulin sensitivity and adipokines APN,RBP4,visfatin and TNF-α in patients with gestational diabetes mellitus(GDM). Methods A total of 101 patients with gestational diabetes( GDM group) and 50 pregnant women with normal blood sugar( control group) were recruited to detect the serum levels of correlative biochemical indexes,APN,RBP4,visfatin,TNF-α and 25OHD3 using an HPLC method. Twenty-four patients in the GDM group diagnosed with vitamin D deficiency(<25 nmol·L-1 ) were randomized to receive either 1,25(OH) 2D3(0. 25 μg·d-1) orally or no treatment. Serum levels of correlative biochemical indexes were detected after 1 month. Results GDM patients had 25OHD3 levels significantly lower than the control group(P<0. 05),APN levels lower than the control group,and RBP4,visfatin,TNF-α levels significantly higher than the control group(all P<0. 05). After 1 month of 1,25(OH) 2D3 treatment,HOMA-IR increased,while HOMA-β decreased. APN levels was positively correlated(r= 0. 526) with 25OHD3;RBP4,visfatin,TNF-α decreased and were negatively correlated with 25OHD3( r values were -0. 272,-0. 153,-0. 072). Conclusion Vitamin D can reduce the adipokines RBP4,visfatin,TNF-α,increase APN,and thus play a protective role for gestational diabetes.

Objective:To explore the implementation status and influencing factors of enhanced recovery after surgery (ERAS) in perioperative management of patients undergoing total hip arthroplasty.Methods:This study was a cross-sectional study. From May to December 2022, purposive sampling was used to select 186 orthopedic nurses from 9 ERAS pilot hospitals in Beijing as the research subject. A self-designed questionnaire was used to investigate the implementation status of ERAS. Pearson correlation was used to analyze the correlation between Nurse ERAS Implementation Status Questionnaire scores and ERAS Behavioral Intention Questionnaire scores. Multiple linear regression was used to analyze the influencing factors of ERAS in perioperative nursing of patients undergoing total hip arthroplasty.Results:A total of 186 questionnaires were distributed and 186 valid questionnaires were collected, with an effective response rate of 100.00% (186/186). The total score of the Nurse ERAS Implementation Status Questionnaire was (116.49±20.71), and the standardized scores for each dimension from high to low were follow-up management (80.22±20.44), intraoperative period (78.98±15.17), preoperative period (74.72±14.09), and postoperative period (69.77±15.94). The total score of the ERAS Behavioral Intention Questionnaire was (77.39±15.08), and the standardized scores of each dimension from high to low were subjective norm (79.93±19.01), behavioral intention (77.69±19.61), behavioral attitude (74.19±15.77), and perceived behavioral control (64.41±14.69). The nurse's professional title, familiarity with ERAS, ERAS training, and subjective norm were the influencing factors of the specific implementation status score of ERAS ( P<0.05), explaining 40.9% of the total variance. Conclusions:Nurses should strengthen training on ERAS, increase their familiarity with knowledge, and adopt various incentive measures to further enhance the implementation of ERAS programs in clinical practice.

Background::Lung cancer is the most common cancer and a leading cause of cancer-related deaths globally. The aim of this study was to evaluate the incidence and mortality of lung cancer worldwide in 2022 and to project the number of new cases and deaths due to lung cancer in China and the United States in 2050.Methods::In this study, data from the GLOBCAN 2022 database were used to analyze lung cancer incidence and mortality. The current status of lung cancer incidence and deaths was described by country/region, sex, age, and the human development index (HDI), and future lung cancer incidence and deaths in China and the United States were projected for 2050.Results::Globally, an estimated 2,480,675 new lung cancer cases and 1,817,469 lung cancer-related deaths occurred in 2022, with age-standardized incidence rates (ASIRs) and age-standardized mortality rates (ASMRs) of 23.6/100,000 and 16.8/100,000, respectively. In China, the ASIR and ASMR for male lung cancer patients were approximately 1.7 times and 2.7 times greater than those for female lung cancer patients, respectively. The ASIR and ASMR in high-HDI countries were approximately 8.5 times and 6.5 times those in low-HDI countries, respectively. It is estimated that in 2050, there will be approximately 1120 thousand new cases and 960 thousand deaths among Chinese men, 680 thousand new cases and 450 thousand deaths among Chinese women, approximately 170 thousand new cases and 110 thousand deaths among American men, and 160 thousand new cases and 90 thousand deaths among American women.Conclusions::There are significant differences in the incidence and mortality of lung cancer among different regions and sexes. Therefore, sex factors need to be considered in the prevention, screening, and treatment strategies of lung cancer, and the implementation of tertiary prevention measures for lung cancer, especially primary and secondary prevention, needs to be actively promoted.

Background Healthy lifestyle is one of the important factors affecting individual health. How to promote residents' cognition of healthy lifestyle has become an urgent practical problem for the whole society. However, there is no residents' healthy lifestyle cognitive indexes available with consideration of carbon peaking and carbon neutrality. Objective To construct a cognitive index system for providing effective assessment on residents' cognition of healthy lifestyle under the background of carbon peaking and carbon neutrality. Methods Based on the health belief model, a preliminary cognitive index system of residents' healthy lifestyle under the background of carbon peaking and carbon neutrality was proposed after literature study and relevant policy review. Then three rounds of indicator importance evaluation and screening by Delphi method were conducted before the index system was finally constructed. The weights of all levels of indicators were determined using analytic hierarchy process. In addition, a self-assessment questionnaire was developed based on the index system. The questionnaire was utilized to conduct a survey among 200 residents by convenience sampling in Shenyang, Liaoning Province from November to December 2021. The survey was used to examine the reliability and validity of the indicator system. Results The effective recovery rates of the three rounds of Delphi method were all 100%. The authority coefficient was 0.84. The Kendall's W consistency test showed good expert consistency (P<0.001). Finally, a cognitive index system of residents' healthy lifestyle under the background of carbon peaking and carbon neutrality was initially constructed, including 4 first-level indicators, 8 second-level indicators, and 35 third-level indicators. Among them, the weights of the first-level indicators were 0.4541 for practice cognition, 0.2248 for benefit and obstacle cognition, 0.1626 for action clue cognition, and 0.1585 for risk cognition, respectively. The correlation coefficients between each indicator were from 0.586 to 0.977 (P<0.01). The overall Cronbach's α coefficient was 0.95, indicating high reliability. Invited experts agreed that the entries were representative and the content validity of the constructed indicator system was good. The factor analysis also showed that the structure validity was good. Conclusion The proposed index system for residents' cognition of healthy lifestyle show good reliability and validity, which can be used as an effective assessment tool for residents' healthy lifestyle cognition under the background of carbon peaking and carbon neutrality. It can provide a scientific and theoretical basis for promoting residents' cognition and practice of healthy lifestyle.

Abstract
OBJECTIVE To clarify the resource status and diversity of endemic medicinal plants in Shaanxi province. METHODS The species specificity, species composition, faunal composition, family and genus types, medicinal value and endangerment degree of endemic medicinal plants in Shaanxi province were studied by literature review.RESULTS There were 713 species of 331 genera and 101 families endemic to Chinese medicinal plants in the study area. Fifteen species were naturally distributed only in Shaanxi province, and the remaining 698 species were also naturally distributed in other provinces of China. Among the 713 species, 233 species(69 families, 159 genera) were not collected from the fourth resource census in Shaanxi province. There were 11 species of pteridophytes in 7 families and 11 genera, 14 species of gymnosperms in 4 families and 10 genera, 627 species of dicotyledons in 82 families and 278 genera, and 59 species of monocots in 8 families and 32 genera. The endemic life forms of medicinal plants in the study area were mostly herbaceous, followed by shrubs and trees, and semi-shrubs and epiphytes accounted for the least. There were 9 families with ≥ 20 species and 4 families with ≥ 10 species in the study area. The 90 families belonging to the endemic species of medicinal plants in Shaanxi province were divided into 13 distribution types and 9 variations, and the tropical distribution(2-7 categories) had a total of 34 families. There were 5 endemic species of medicinal plants in the study area under the national class I key protection, and 14 species under the national class II key protection. There were 26 species of plants under local key protection in Shaanxi province. There were 21 plants that could be used as original plants for medicinal materials included in the Pharmacopoeia of the People's Republic of China(2020 edition). CONCLUSION The endemic species of medicinal plants in Shaanxi province are rich in resources and have good medicinal value. However, the growing environment of some plants is harsh and human damage is serious. Multiple protection measures should be taken to maintain the species diversity and sustainable development of resources in the study area.

Objective:This paper provides a brief overview of the epidemiology of colorectal cancer in China and around the world, and discusses how to prevent colorectal cancer to reduce its disease burden.Method:Using the official database of GLOBOCAN 2020, the China Cancer Registry Annual Report compiled by the National Cancer Center, and data from CONCORD-3.Data management was performed by Microsoft Excel 2016 and R 4.2.1 Relevant graphs were generated using the ggplot2 package for result visualization.Result:An estimated 1 931 590 people were diagnosed with colorectal cancer worldwide in 2020 with an age-standardized incidence rate of 19.5 per 100 000. There were about 935 173 deaths caused by colorectal cancer internationally, with an age-standardized mortality rate of 9.0 per 100 000. Overall, colorectal cancer was the fourth most commonly diagnosed cancer and the third leading cause of cancer-related death worldwide in 2020. In China, the age-standardized incidence rate and mortality rate of colorectal cancer was 17.3 per 100 000 and 7.8 per 100 000, respectively. Gender differences in trends were observed, with a decreasing trend in incidence and mortality among females and an increasing trend in incidence and mortality among males. The primary risk factors for colorectal cancer include age, genetic factors, gastrointestinal disorders, dietary habits, and lifestyle et al.Conclusions:Colorectal cancer poses a significant burden globally and in China. The occurrence of colorectal cancer is closely related to physiology, genetics, behavioral habits, lifestyle, and disease factors. To better control the colorectal cancer burden with the lowest cost, specific measures should be taken to reduce exposure to established risk factors. By combining the disease prevention and control strategies of tertiary prevention in China with the characteristic factors of colorectal cancer, the incidence and mortality of colorectal cancer may be effectively controlled.

Lung cancer remains one of the leading cause of global cancer-related mortality, posing a significant burden of disease. Tobacco exposure stands as the foremost risk factor for lung cancer. Since the 1960, global efforts have gradually been implemented to control tobacco exposure, consequently reducing tobacco exposure levels within populations. This shift in exposure levels may have altered the epidemiological characteristics of lung cancer globally. This study aims to describe global lung cancer incidence data across five dimensions: age, gender, region, stage at diagnosis, and survival status, using global cancer registry data and relevant research findings. The objective is to elucidate the current epidemiological features of lung cancer worldwide, providing a scientific basis for lung cancer prevention and control. Furthermore, this study offers corresponding measures and recommendations for lung cancer prevention and control, aligning with the three-tiered cancer prevention strategy. Findings indicate that the incidence and mortality burden of lung cancer is significantly higher among the elderly population (aged 65 years and above) compared to the working-age population (aged 15-64 years). The aged-standardized incidence rate of lung cancer remains higher in males than in females, but the overall aged-standardized incidence rate of lung cancer in males shows a declining trend, while that in females shows an increasing trend. Regions with high and very high human development index (HDI) exhibit a substantially higher incidence and mortality burden of lung cancer compared to regions with low and very low HDI. Japan ranks highest in the diagnosis of stage Ⅰ lung cancer, with a diagnosis rate of 38.6%. Its age-standardized 5-year net survival rate is relatively high at 32.9%. Despite improvements in the survival status of lung cancer in certain countries like China and Japan, the overall prognosis for lung cancer remains pessimistic. Given the current epidemiological characteristics of lung cancer, reinforcing tobacco control measures and reducing female-specific lung cancer risk factors stand as significant goals for primary prevention. Promoting low-dose computed tomography screening for high-risk population, minimizing false-positive rates in lung cancer screening, and promoting medical system reforms and standardized treatment constitute principal measures for secondary and tertiary lung cancer prevention, respectively.

Objective:To analyze the incidence, mortality, and survival status and trends of lung cancer in China.Methods:The data of incidence, mortality, disability-adjusted life year (DALY), and survival status and trends of lung cancer in China were collected from GLOBOCAN 2020, Global Burden of Disease Study in 2019 (GBD2019) databases, and the CONCORD-3 project report. Joinpoint 5.0 software was used to analyze the age-standardized incidence rate (ASIR) and age-standardized mortality rate (ASMR) of lung cancer in China from 1990 to 2019. Data management was conducted by using Excel 2016, and relevant graphical representations were generated using the ggplot2 package in software R 4.2.1.Results:In 2020, a total of 815 563 lung cancer cases were newly reported in China with the ASIR of 34.8/100 000, in which 539 181 cases were reported in men, with the ASIR of 47.8/100 000, and 276 382 cases were reported in women, with the ASIR of 22.8/100 000. A total of 714 699 lung cancer deaths were reported in 2020, with the ASMR of 30.2/100 000. Among these deaths, there were 471 546 deaths in men with the ASMR of 41.8/100 000, and 243 153 deaths in women with the ASMR of 19.7/100 000. From 1990 to 2019, the ASIR and ASMR of lung cancer in both men and women showed increasing trends ( P<0.05). However, from 2010 to 2019, the ASIR and ASMR of lung cancer in men showed decreasing trends, with annual percent of change (APC) of -0.17% (95% CI: -0.24% - -0.09%) and -0.69% (95% CI: -0.79% - -0.59%), respectively. The ASIR and ASMR of lung cancer in women showed increasing trends from 2016 to 2019, with APC of 3.33% (95% CI: 2.73% - 3.88%) and 2.61% (95% CI: 1.99% - 3.28%), respectively. The five-year net survival rate for lung cancer was 19.8% in China (95% CI:19.4% - 20.2%) from 2010 to 2014. Conclusions:The morbidity and mortality of lung cancer in China remain at high levels, the prognosis of lung cancer was poor, and the disease burden of lung cancer would become more serious in the context of population aging, so three-level prevention of lung cancer should be implemented to address this problem. In addition, attention should be paid to the increasing trends of ASIR and ASMR of lung cancer in women in recent years. Further investigation of risk factors and targeted prevention are needed to curb the rising trend in the incidence of lung cancer in women.
