Third， it discussed the application scenarios of medicinal and edible materials in proactive health and technological responses to population aging， as well as the future research and development of medicinal and edible materials. By exploring in depth the unique value and importance of medicinal and edible materials， the paper lays a theoretical foundation for improving the health care capabilities of TCM and contributes new strategies derived from TCM to healthy aging.

ObjectiveTo observe the effect of gene mutation on the effectiveness of arsenic-containing Chinese herbal compound formulas in the treatment of myelodysplastic syndromes （MDS） of different traditional Chinese medicine （TCM） patterns， so as to provide the basis for the clinical application. MethodsClinical data of 442 MDS patients who were treated with arsenic-containing herbal compound formulas were retrospectively collected， including the baseline demographic and clinical characteristics of the patients. Based on the TCM four examinations， the patients were divided into the spleen-kidney deficiency group as well as the qi-yin deficiency group， and according to the results of the next-generation sequencing （NGS） test， they were divided into the group with and without gene mutation respectively. The influence of gene mutation on the clinical effectiveness of patients with different TCM patterns was analyzed， the baseline demographic and clinical characteristics of the patients with different outcomes of the two TCM patterns were compared， and multivariate Logistic regression analysis was conducted on the influencing factors of the effective rate of MDS patients with gene mutation. ResultsA total of 190 cases were included in the spleen-kidney deficiency group （119 cases with gene mutation） and 43 cases in the qi-yin deficiency group （23 cases with gene mutation）. No statistically significant differences were noted in effectiveness assessment， total effective rate， and total response rate between the spleen-kidney deficiency group and the qi-yin deficiency group （P＞0.05）. In the spleen-kidney deficiency group， the total effective rate of MDS with gene mutation was 65.55% （78/119）， which was lower than 80.28% （57/71） of MDS without gene mutation， with statistical significance （P = 0.033）， while no statistical differences in effectiveness assessment and total response rate were noted （P＞0.05）. In the qi-yin deficiency group， no statistical differences were observed in effectiveness assessment， total effective rate， and total response rate of the patients in with or without gene mutation （P＞0.05）. In the spleen-kidney deficiency group with gene mutation， the rate of complex karyotype （P = 0.031） and the mutation rate of CBL gene （P = 0.032） in the ineffective population were higher than those in the effective population， while the mutation rate of DDX41 gene in the effective population was higher than that in the ineffective population （P = 0.033）. No statistically significant differences were found in other gene mutations， age， gender distribution， number of gene mutations， bone marrow hyperplasia degree， blast cell range， reticular fiber tissue proliferation or not， and prognosis of chromosomal abnormalities between the effective and ineffective populations （P＞0.05）. In the qi-yin deficiency group with gene mutation， no statistically significant differences were found in various items between populations with different outcomes （P＞0.05）. Multivariate Logistic regression analysis showed that complex karyotype， CBL mutation， and DDX41 mutation were independently associated with the effective rate of MDS with spleen-kidney deficiency and gene mutation （P＜0.05）. DDX41 mutation was an independent protective factor in the spleen-kidney deficiency group （OR＞1）， while complex karyotype and CBL mutation were independent risk factors （OR＜1）. ConclusionThe arsenic-containing TCM compound formulas exhibited better effectiveness in MDS with spleen-kidney deficiency pattern without mutation； and in MDS with spleen-kidney deficiency pattern without complex karyotypes， CBL mutation， and with DDX41 mutations. Furthermore， DDX41 mutation was an independent protective factor in the spleen-kidney deficiency group， while complex karyotype and CBL mutation were independent risk factors. In MDS with qi-yin deficiency pattern， gene mutation-related factors showed no significant impact on the effectiveness of arsenic-containing TCM compound formulas.

AIM: To compare the effectiveness of foldable capsular body(FCB)with traditional scleral buckling(SB)in the treatment of experimental retinal detachment animal models.METHODS: After successfully establishing rhegmatogenous retinal detachment(RRD)animal models, 24 New Zealand white rabbits were randomly divided into three groups(RRD models group, SB group, and FCB group), with 8 rabbits in each group. The FCB and SB groups underwent SB and FCB surgeries for the RRD animal models, while the RRD models group only consists of RRD models without any surgical intervention during the follow-up period. The follow-up duration was 3 mo. Wide-field neonatal fundus imaging system and ophthalmic B-ultrasound were used to assess the fundus conditions before and after surgery. The Icare® TONOVET Plus tonometer was utilized to evaluate intraocular pressure changes before and after surgery. The Eaton and Draize scoring systems were selected to monitor postoperative inflammatory reactions.RESULTS: The retinal reattachment rates in the FCB and SB groups were 87.5% and 75.0%, respectively, with no statistically significant difference between the groups(P>0.05). The intraocular pressure in both the FCB and SB groups increased postoperatively compared to preoperative levels(P<0.01), and there were no significant differences in intraocular pressure at any time points during the follow-up period between the groups(P>0.05). The intraocular pressure in the RRD models group remained at a low level throughout the follow-up period. The average surgical time for the FCB group was 16.87±2.29 min, which was shorter than 46.25±4.74 min in the SB group(t=-15.166, P<0.001). According to the Eaton and Draize scoring systems, the FCB group had lower grades of conjunctival hyperemia and edema in the early postoperative period compared to the SB group, indicating milder inflammatory reactions(P<0.05).CONCLUSION: Both FCB and SB are effective in treating experimental RRD. Compared to SB, FCB is simpler to operate, and also has a shorter surgical time and milder postoperative inflammatory reactions.

Objective Studies on the expression and location of zinc finger protein A20 (A20) and connective tissue growth factor (CTGF) in liver tissues of patients with chronic hepatitis B were conducted, and the relationship between them and liver fibrosis was determined by FibroScan. Methods Studies on A20 and CTGF in liver tissues of 160 patients with chronic hepatitis B were conducted in accordance with the stage of pathological fibrosis and inflammation of the liver, and quantitative immunohistochemistry test was conducted, and statistical analysis was conducted by FibroScan. Results The expressions of A20 and CTGF in liver tissues increased with the aggravation of liver pathological fibrosis and inflammation, and there were significant differences between each stage and the control group (P<0.05), and there were significant differences between adjacent groups (P<0.05). Studies have shown that FibroScan increases along with pathological fibrosis and inflammation in the liver. There are significant differences between the stage and the control group (P<0.05), and no significant differences between the adjacent groups (P>0.05). There was positive correlation between liver A20 and CTGF, r=0.796 (P<0.05). Conclusions In patients with chronic hepatitis B, A20, CTGF and FibroScan are positively correlated with the degree of liver fibrosis, and A20 and CTGF are also positively correlated with the degree of liver inflammation, which can be used as indicators to evaluate the degree of liver inflammation and fibrosis, and further guide the anti-inflammatory and anti-fibrosis treatment of patients.

Objective:To use the best evidence of noninvasive mechanical ventilation related pressure injury prevention in the clinic guided by integrated promoting action on research implementation in health services framework (i-PARIHS) and evaluate its effect.Methods:This study is an unsynchronized before and after control study. Convenience sampling method was used to select patients receiving non-invasive mechanical ventilation from 7 wards of Beijing Hospital from October 2019 to September 2021. A total of 575 patients receiving non-invasive mechanical ventilation from October 2019 to September 2020 were included in the control group and 602 patients from October 2020 to September 2021 were included in the trial group. The control group adopted the usual care measures, and the trial group applied the prevention program for noninvasive ventilation related facial pressure injuries. The incidence of pressure injury was compared between the two groups. Nurses in 7 wards were investigated before and after the intervention program to compare the changes of knowledge level.Results:In the control group, there were 354 males, 221 females, aged (77.13 ± 14.49) years old; in the trial group there were 392 males, 210 females, aged (75.60 ± 14.27) years old. The incidence of pressure injury in the trial group was lower than the control group, but showed no significant difference ( P>0.05). In the control group, 11 cases suffered pressure injury, including 5 cases in stage 2, 6 cases in stage 3 and above. There were 9 cases in the trial group, including 8 in stage 2 and 1 in stage 3 and above. The severity of pressure injury in the trial group was lower than that in the control group, and the difference was significant ( χ2 = 3.83, 4.11, both P<0.05). The scores of the nurse′pressure injury knowledge increased from (6.77 ± 1.53) points to (7.15 ± 1.47) points, with a significant difference ( t = -2.31, P<0.05). Conclusions:Management of the prevention of noninvasive mechanical ventilation related facial pressure injury through evidence-based practice can reduce its incidence, reduce its severity, and it is beneficial to improve the clinical nurses' prevention knowledge and clinical practice level of facial pressure injury related to non-invasive mechanical ventilation.

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.
