Objective To analyze the evaluation and influencing factors of healthy enterprises in Hubei Province from 2020 to 2023. Methods A total of 351 enterprises participated in the healthy enterprise evaluation in Hubei province were selected as the study subjects using the judgmental sampling method. The differences in evaluation results including scales, industry sector, and ownership type of the enterprises were compared. Results The median and the 25th and 75th percentiles [M (P₂₅, P₇₅)] of the evaluation score among the 351 enterprises was 869 (838, 941) points. The evaluation pass rate was 82.3%. The M(P₂₅, P₇₅) of scores for the management system, health environment, health management and services, health culture, and health outcome review were 183 (174, 192), 190 (181, 198), 340 (321, 376), 133 (122, 142), and 26 (24, 28) points, with the score percentage of 91.5%, 86.4%, 85.0%, 88.7%, and 86.7%, respectively. The deduction rate exceeded 50.0% in six items, which predominantly concentrated within the primary indicator of the health management and services, among the tertiary indicators. The result of multiple linear regression analysis revealed that smaller enterprises had significantly lower evaluation scores (P<0.05), and domestically funded enterprises scored significantly lower than those with investment from Hong Kong, Macao and Taiwan, or foreign investments (all P<0.05). Conclusion Health management and services represent a weak area in healthy enterprise development in Hubei Province. It was suggested to improve policy incentives and support for medium-, small- and micro-sized enterprises, and domestically funded enterprises, to enhance healthy enterprise development levels.

Digital technologies have become an integral part of complete denture restoration. With advancement in computer-aided design and computer-aided manufacturing (CAD/CAM), tools such as intraoral scanning, facial scanning, 3D printing, and numerical control machining are reshaping the workflow of complete denture restoration. Unlike conventional methods that rely heavily on clinical experience and manual techniques, digital technologies offer greater precision, predictability, and efficacy. They also streamline the process by reducing the number of patient visits and improving overall comfort. Despite these improvements, the clinical application of digital complete denture restoration still faces challenges that require further standardization. The major issues include appropriate case selection, establishing consistent digital workflows, and evaluating long-term outcomes. To address these challenges and provide clinical guidance for practitioners, this expert consensus outlines the principles, advantages, and limitations of digital complete denture technology. The aim of this review was to offer practical recommendations on indications, clinical procedures and precautions, evaluation metrics, and outcome assessment to support digital restoration of complete denture in clinical practice.

Natural products are important sources for the discovery of anti-tumor drugs. Evodiamine is the main alkaloid component of the traditional Chinese herb Wu-Chu-Yu, and it has weak antitumor activity. In recent years, a number of highly active antitumor candidates have been discovered with a significant progress. This article reviews the research progress of evodiamine-based antitumor drug design strategies, in order to provide reference for the development of new drugs with natural products as leads.

Cancer stem cells,a small population of cells with self-renewal and multidirectional differenti-ation potential in tumor tissues,can initiate primary tumors and mediate treatment resistance,tumor re-currence,and metastasis,but the mechanism of how they affect colorectal cancer at the cellular level is unknown.Therefore,in this study,we explored the effect of cancer stem cells and their exosomes on the malignant phenotype of colorectal cancer.First,CD 166+CD44+cancer stem cells(CSCs)were isolated from colorectal cancer tumor tissues,and then cancer stem cell-derived exosomes(CSCexo)and colorec-tal cancer SW480 cell-derived exosomes(Sexo)were extracted by ultracentrifugation.Then,exosomes were subjected to NTA particle size analysis,electron microscopic observation and identification by West-ern blotting.Subsequently,the successfully isolated CSC and CSCexo were co-cultured with colorectal cancer SW480 cells.The apoptosis rate of SW480 cells after co-culture was found to decrease from 20％to about 13％by CCK-8,apoptosis assay(P＜0.01)and the invasive ability was significantly increased(P＜0.001)after co-culture with CSC or CSCexo.In addition,in vivo animal experiments revealed that the tumor growth rate of the S-exo treatment group was slower than that of the CSCexo treatment group,and that CSCexo inhibited the drug efficacy of 5-FU against colorectal cancer tumors.PET/CT imaging,immunohistochemical analysis,and Western blotting experiments showed that CSCexo enhanced the up-take of the glucose analog 18F-FDG and the expression of the glycolytic enzymes HK2,PFKFB2,PKM2,and LDHA in colorectal cancer.In addition,interfering with the expression of glycolytic enzymes with siRNAs blocked the drug resistance induced by CSCexo.In summary,this study demonstrates that color-ectal cancer stem cells deliver exosomes that affect tumor glucose metabolism pathways and promote chemotherapy resistance and invasive ability,revealing the mechanism of formation and dynamic changes in the malignant tumor microenvironment.

Objectives:To investigate the feasibility of using bedside echocardiography on the evaluation of potential donors with different causes of brain death for adult heart transplantation. Methods:Bedside echocardiographic and clinical data of consecutive potential donors for adult heart transplantation evaluated by the team of our institution from February 2018 to December 2020 were retrospectively analyzed.Based on different causes of brain death,the potential donors were divided into stroke(ischemic or hemorrhagic,n=398)and non-stroke(head trauma,brain tumor,anoxia,n=272)groups.The clinical and echocardiographic features were compared between the two groups.A total of 350 donors were assigned to our hospital by the China Organ Transplant Response System and met the inclusion criteria for donor selection.There were 195 cases in the stroke group and 155 in the non-stroke group.Retrieval operations were performed and the retrieval rate of hearts for transplantation in stroke donors was compared to that in non-stroke donors. Results:(1)Among the 670 potential heart donors,compared with the non-stroke group,donors in the stroke group were significantly older,had higher body mass index,larger left ventricular end-diastolic diameter,thicker interventricular septum,higher rates of echocardiographic abnormalities,higher prevalence of hypertension(all P<0.001).Among the 670 potential heart donors,17.5%(117 cases)did not meet the echo selection criteria,the common causes were left ventricular hypertrophy(59 cases,50.4%),left ventricular ejection fraction<50%(27 cases,23.1%),wall motion abnormalities(21 cases,17.9%),and left ventricular dilation(14 cases,12.0%).(2)Among the 350 donors who had met the selection criteria and assigned to our hospital by the China Organ Transplant Response System and underwent retrieval operation,70.3%(246 cases)were successfully procured,110 cases(44.7%)in the stroke group and 136 cases(55.3%)in the non-stroke group.The retrieval rate of stroke donors(110/195,56.4%)was lower compared with that of non-stroke(136/155,87.7%,P<0.001),104 cases(29.7%)were not retrieved,and the leading cause of unsuccessful organ retrieval was the occlusion of at least one major coronary artery(91 cases,87.5%). Conclusions:Bedside echocardiography is of great value as a screening tool for cardiac donors.Cardiac structures of the potential donor with stroke as the cause of brain death were different from those with non-stroke causes.The retrieval rate of stroke donors was lower than that of non-stroke donors,even if the initial criteria for donor selection were fulfilled.

Objective:To explore the trends and outcomes for heart transplantation (HT) in elderly recipients and further examine the related risk factors.Methods:Between June 2004 and December 2021, retrospective review was conducted for the relevant clinical data and age distribution of 1044 HT recipients aged ≥18 year at Fuwai Hospital. The study population was assigned into two groups of elder (≥60 year, n=877) and non-elder (<60 year, n=157). Subgroup analysis was made between recipients aged <65 year (n=107) and those aged ≥ 65 year (n=50) in elder group. Baseline demographic profiles, clinical data, in-hospital and one-year post-transplant mortality and long-term survival were compared between two groups. Then a further comparison of long-term survival was conducted among the groups of non-elder, elder aged <65 year and elder aged ≥65 year. Cox proportional risk regression and multivariate Logistic regression models were utilized for examining the relevant risk factors for cumulative survival rate and short-term mortality. Kaplan-Meier analysis was employed for plotting survival curves and Log-rank test for comparison. Multivariate Cox proportional risk regression model was utilized for examining the relevant risk factors for cumulative survival rate and multivariate Logistic regression model for analyzing the relevant risk factors for short-term mortality. After adjusting for other confounding factors, the impact of recipient age on survival post-HT was determined.Results:The number of elderly HT recipients spiked annually at our center while average age of adult recipients and average age of elderly recipients have remained relatively constant. The median follow-up period was 6.5 years. Regarding baseline data, statistically significant differences existed in ratio of males [84.7%(113/157) vs 77.5%(687/877)], hypertension history [20.4%(32/157) vs 8.9%(79/877)], smoking history [47.1%(74/157) vs 36.1%(320/877)], diabetic history [33.8%(53/157) vs 14.7%(130/877)], preoperative ICD/CRT/CRT-D implantation [28.0%(44/157) vs 18.0%(160/877)], value of creatinine [(105.3±25.3) vs (96.8±35.0) μmol/L], IMPACT score [(6.9±2.4) vs (4.2±2.9) point], serum total bilirubin [19.7(13.6, 30.3) vs 23.7(15.8, 36.8) μmol/L], mean pulmonary arterial pressure [(26.0±10.3) vs (29.7±11.0) mmHg (1 mmHg=0.133 kPa)] and ischemic duration [(274.7±105.6) vs (296.0±120.4) min] (all P<0.05). No significant inter-group difference existed in in-hospital mortality [4.5%(7/157) vs 4.7%(42/887)] or 1-year mortality [5.7%(9/157) vs 6.5%(58/887)] ( P=0.88, P=0.70); in-hospital mortality and 1-year postoperative mortality of recipients aged ≥65 years 10.0%(5/50) and 14.0%(7/50) were both higher than those aged <65 year [1.9%(2/107), 1.9%(2/107)]. The differences were both statistically significant ( P=0.02, P<0.01). Kaplan-Meier survival analysis indicated that long-term survival rate was lower in elder group than that in non-elder group and the difference was statistically significant ( P=0.046). Long-term survival rate of elders aged ≥65 year was lower than that of non-elders aged <65 year and the difference was statistically significant ( P<0.01). Regression analysis indicated that age of recipient ≥65 year, preoperative creatinine ≥133 μmol/L, preoperative total bilirubin ≥25.65 μmol/L and preoperative support of extracorporeal membrane oxygenation (ECMO) were independent risk factors for short/long-term mortality post-HT. Conclusion:Although long-term prognosis of elderly recipients is slightly worse than that of non-elderly ones, in-hospital mortality and one-year postoperative mortality are similar between two groups. For elderly recipients with fewer comorbidities and better preoperative status, they should not be excluded from HT based solely upon age. The long-term prognosis of recipients aged ≥65 year remains poor and HT decisions should be made carefully.

Objective To evaluate the effect of renal insufficiency before heart transplantation on perioperative death, complications and long-term survival, and to compare the differences between preoperative serum creatinine (Scr) and estimated glomerular filtration rate (eGFR) in preoperative risk assessment. Methods Clinical data of 1 095 heart transplant recipients were retrospectively analyzed. According to preoperative Scr level, all recipients were divided into the Scr < 133 μmol/L(n=980), Scr 133-176 μmol/L (n=83) and Scr≥177 μmol/L groups (n=32). According to preoperative eGFR, all recipients were divided into eGFR≥90 mL/(min·1.73m²) (n=436), eGFR 60-89 mL/(min·1.73m²) (n=418) and eGFR < 60 mL/(min·1.73m²) groups (n=241). Clinical prognosis of postoperative renal function, perioperative and long-term outcomes of recipients were compared among different groups. The effect of eGFR and Scr level on renal function injury and long-term survival after heart transplantation was assessed. Results With the increase of preoperative Scr level, the proportion of recipients undergoing postoperative continuous renal replacement therapy (CRRT) was increased, the proportion of recipients receiving postoperative mechanical circulatory support was elevated, the incidence of postoperative complications was increased, the duration of mechanical ventilation and intensive care unit(ICU) stay was prolonged, and the in-hospital fatality was increased. The differences among three groups were statistically significant (all P < 0.05). With the decrease of preoperative eGFR, the proportion of recipients receiving postoperative CRRT was increased, the proportion of recipients using postoperative intra-aortic balloon pump (IABP) was elevated, the duration of mechanical ventilation and ICU stay was prolonged, and the in-hospital fatality was increased. The differences among three groups were statistically significant (all P < 0.05). Scr≥177 μmol/L was an independent risk factor for postoperative death [adjusted hazard ratio (HR) 3.64, 95% confidence interval (CI) 1.89-6.99, P < 0.01]. Among different groups classified by Scr and eGFR, the cumulative incidence rate of postoperative renal function injury and long-term survival rate were statistically significant among three groups (all P < 0.05). In patients with preoperative Scr < 133 μmol/L, the cumulative incidence rate of postoperative long-term renal function injury was significantly increased with the decrease of preoperative eGFR (P < 0.01). There was no significant difference in postoperative long-term survival rate among patients stratified by different eGFR (P > 0.05). Conclusions Renal insufficiency before heart transplantation is associated with poor perioperative and long-term prognosis. Preoperative Scr and eGFR are the independent risk factors for postoperative renal function injury. Scr yields low sensitivity in the assessment of preoperative renal function, whereas it has high accuracy in predicting perioperative death risk. And eGFR is a more sensitive parameter to evaluate preoperative renal function, which may identify early-stage renal functional abnormality and take effective measures during early stage to reduce adverse effect on prognosis.

Objective To evaluate the effect of extracorporeal membrane oxygenation (ECMO) on early allograft dysfunction (EAD) after heart transplantation. Methods Clinical data of 614 heart transplant recipients were retrospectively analyzed. All recipients were divided into the ECMO group (n=43) and non-ECMO group (n=571) according to postoperative application of ECMO. In the ECMO group, the conditions of recipients undergoing ECMO after heart transplantation were summarized. Perioperative status and long-term prognosis of recipients were compared between two groups. Results Among 43 recipients undergoing ECMO, 17 cases underwent thoracotomy due to bleeding, 10 cases of infection, 4 cases of venous thrombosis of the lower limbs, and 1 case of stroke, respectively. Twenty-six recipients were recovered and discharged after successful weaning from ECMO, six died during ECMO support, six died after weaning from ECMO, five received retransplantation due to unsuccessful weaning from ECMO, and only one survived after retransplantation. Compared with the non-ECMO group, intraoperative cardiopulmonary bypass duration was significantly longer, the proportion of recipients requiring postoperative intra-aortic balloon pump (IABP), dialysis due to renal insufficiency, reoperation for hemostasis, infection, mechanical ventilation time≥96 h and tracheotomy was significantly higher, and the length of postoperative intensive care unit (ICU) stay was significantly longer in the ECMO group (all P < 0.05). The survival rate after discharge and 90-d survival rate in the ECMO group were 63% and 96%, significantly lower than 97% and 100% in the non-ECMO group (both P < 0.05). Survival analysis showed that the long-term survival rate in the ECMO group was significantly lower than that in the non-ECMO group (P < 0.05). After excluding the recipients who died within 90 d after heart transplantation, no significant difference was observed in the long-term survival rate (P > 0.05). Conclusions ECMO is an effective treatment of EAD after heart transplantation. The short-term survival rate of recipients using ECMO after heart transplantation is lower than that of those who do not use ECMO, and there is no significant difference in long-term survival of recipients surviving 90 d after heart transplantation.

Aim To study the therapeutic effect of Balanophora polysaccharide(BPS)on gastric ulcer(GU)induced by acetic acid in rats and to investigateits mechanisms. Methods Sixty male SD rats were randomly divided into sham-operated group, GU model group, omeprazole positive group(3.6 mg·kg-1), and low, medium and high dose of BPS treatment groups(100, 200 and 400 mg·kg-1). The GU model group was prepared by acetic acid cautery method, and the morphology and pathological changes of ulcers were observed by visual observation combined with HE staining, and the ulcer area and inhibition rate were measured and calculated; superoxide dismutase(SOD)activity, malondialdehyde(MDA)content and glutathione peroxidase(GSH-PX)activity were measured by enzymatic assay; tumor necrosis factor-α(TNF-α)and interleukin-6(IL-6)content were detected by ELISA. The expression levels of epidermal growth factor(EGF)and epidermal growth factor receptor(EGFR)were measured by immunohistochemistry staining and Western blot. Results Compared with the sham-operated group, obvious ulcer damage was seen in the model group. Compared with the model group, the BPS-treated group showed a significant reduction in ulcer area, an increase in SOD and GSH-PX activity and EGF and EGFR expression levels, and a significant decrease in MDA, TNF-α and IL-6 content. Conclusions BPS has a therapeutic effect on GU in rats, and its mechanism may be related to the inhibition of oxidative stress, suppression of inflammatory stimuli and promotion of regenerative repair of gastric mucosa.
