OBJECTIVE To establish a closed-loop management system for the whole-process traceability of outpatient drugs based on internet of things （IoT） and blockchain technology， and evaluate its implementation effects. METHODS A closed-loop management system for the whole-process traceability of outpatient drugs covering the entire drug lifecycle was designed using drug traceability codes integrated with IoT and blockchain technology. System effectiveness was evaluated from three dimensions： work efficiency， medication management quality and data safety by comparing indicators such as the acceptance time of incoming drugs and the number of collected drug traceability codes before the system implementation （October to December 2024） and after the system implementation （January to March 2025）. RESULTS A closed-loop management system for the whole-process traceability of outpatient drugs， centered around the drug traceability code management system， was successfully established. The acceptance time for incoming drugs was shortened from （4.65±0.26） h before implementation to （0.34±0.08） h after implementation （P＜ 0.05）. The number of collected drug traceability codes increased from 419 018 to 1 236 522， and the coverage rate of traceability codes rose from 28.36% to 89.88% （P＜0.05）. The time pharmacists spent on drug expiry management per week decreased from （128.40±19.20） min to （0.56±0.13） min （P＜0.05）， and the dispensing time for a single prescription （excluding a part of injections and repackaged drugs） was reduced from （143.25±17.67） s to （15.24±10.08） s （P＜0.05）. The time for drug return was reduced from 129.90 （122.32， 137.00） s to 104.36 （89.91， 117.33） s（P＜0.05）； the number of drug dispensing errors decreased from 2 cases to 0 cases. After the system was launched， there were no data security incidents in our outpatient pharmacy. CONCLUSIONS The constructed closed-loop management system for the whole-process traceability of outpatient drugs can significantly enhance drug traceability accuracy and drug management quality， improve pharmacist work efficiency， and reduce drug management risks， thus providing a feasible solution for the digital transformation of hospital pharmaceutical services.

Objective:To investigate the relationship between thyroid-stimulating hormone(TSH) levels and 10-year mortality in women aged 40 years and older.Methods:Residents aged 40 and over in urban areas of Guiyang City who participated in the " Epidemiological Study of Cancer Risk in Patients with Type 2 Diabetes in China(REACTION)" were followed up in 2011. Finally, 5 614 people were enrolled, and the baseline general information, physical examination and TSH detection were carried out. The average follow-up was(9.77±1.55) years, and the treatment and death of thyroid-related diseases were recorded. The Cox proportional hazards model was used to analyze the relationship between TSH level and 10-year mortality in middle-aged and elderly women, and plotting survival time curves(Kaplan-Meier curves) to study the association between elevated TSH levels and lifespan in subjects under 65 years old. Results:The multivariate Cox proportional hazards model showed that compared with the normal group, after multivariate adjustment, the risk of death in the TSH increased group was decreased( HR=0.644, 95% CI 0.478-0.868, P<0.05); after stratifying the elevated TSH group, the risk of death was decreased in the slightly elevated TSH group( HR=0.566, 95% CI 0.405-0.791, P<0.001); the elevated TSH group was further stratified by age. In the group under 65 years old, compared to the normal group, the mildly elevated group showed a reduced risk of mortality( HR=0.429, 95% CI 0.245-0.751, P=0.003). In the group aged 65 and above, there were no statistically significant differences in mortality risk between the mildly elevated group, severely elevated group, and the normal group( P>0.05). In the group under 65 years old, the K-M curve indicated that the survival rate of the mildly elevated TSH group was significantly higher than that of the normal group( χ2=11.931, P=0.003), the difference was statistically significant. Conclusion:Mildly elevated TSH levels in women aged 40-65 years are associated with a reduced risk of all-cause death and longer lifespan.

Objective To evaluate the value of miniprobe endoscopic ultrasound(EUS)in guiding endoscopic treatment of small-diameter(maximum diameter less than 1 cm)and low-grade(G1 grade)rectum neuroendocrine neoplasm(R-NEN),and to provide evidence and clues for its clinical application and further research.Methods The clinical data of 85 cases of low-grade(G1 grade)R-NEN with a maximum diameter of less than 1 cm who underwent endoscopic treatment in our center from January 2014 to December 2020 were retrospectively analyzed.The patients were divided into the EUS group(37 cases)and control group(48 cases)according to whether EUS was performed before endoscopic treatment.The positive rate of incision margin,the incidence of complications,the recurrence rate,the hospital stay,the cost of hospitalization and endoscopic therapy were compared between the two groups.Results The positive rate of incision margin in the EUS group was significantly lower than that in control group(P<0.05).There was no significant difference in the incidence of complications,tumor recurrence rate,hospital stay or hospital costs between the two groups(P>0.05).There was statistically significant difference in the endoscopic therapy between the two groups(P<0.05).Conclusion Evaluating the lesion depth of small-diameter and low-grade(G1 grade)R-NEN before surgery by miniprobe EUS and selecting endoscopic surgery according to its results of can significantly reduce the residual risk of resection margin tumors.

Cornus officinalis,a medicinal and edible plant known for its liver-nourishing properties,has shown promise in inhibiting the activation of hepatic stellate cells(HSCs),crucial indicators of hepatic fibrosis,especially when processed by high pressure wine steaming(HPWS).Herein,this study aims to investigate the regulatory effects of cornus officinalis,both in its raw and HPWS forms,on inflammation and apoptosis in liver fibrosis and their underlying mechanisms.In vivo liver fibrosis models were established by subcutaneous injection of CCl4,while in vitro HSCs were exposed to transforming growth factor-β(TGF-β).These findings demonstrated that cornus officinalis with HPWS conspicuously ameliorated his-topathological injury,reduced the release of proinflammatory factors,and decreased collagen deposition in CCl4-induced rats compared to its raw form.Utilizing ultra-high-performance liquid chromatography coupled with quadrupole time-of-flight mass spectrometer(UHPLC-QTOF-MS)combined with network analysis,we identified that the pharmacological effects of the changed components of cornus officinalis before and after HPWS,primarily centered on the adenosine phosphate(AMP)-activated protein kinase(AMPK)pathway.Of note,cornus officinalis activated AMPK and sirtuin 3(SIRT3),promoting the apoptosis of activated HSCs through the caspase cascade by regulating caspase3,caspase6 and caspase9.small interfering RNA(siRNA)experiments showed that cornus officinalis could regulate AMPK activity and its mediated-apoptosis through SIRT3.In conclusion,cornus officinalis exhibited the ability to reduce inflammation and apoptosis,with the SIRT3-AMPK signaling pathway identified as a potential mecha-nism underlying the synergistic effect of cornus officinalis with HPWS on anti-liver fibrosis.

Adrenocortical carcinoma(ACC)is the most prevalent malignant tumor of the adrenal gland and is characterized by a poor pro-gnosis in its advanced stages.Surgical resection of the tumors is typically limited to patients diagnosed in the clinical stages Ⅰ and Ⅱ,lead-ing to a high postoperative recurrence rate.The combination of mitotane(M)with etoposide(E),doxorubicin(D),and cisplatin(P)(EDP-M)is currently the only approved first-line treatment regimen for advanced ACC.However,the efficacy of chemotherapy and radiation therapy in ACC remains limited.If the EDP-M regimen proves ineffective,there are no standardized or universally accepted second-line systemic treat-ment alternatives.Research advancements in the molecular mechanisms of ACC in recent years has led to increasing investigations on tyr-osine kinase inhibitors(TKIs)targeting EGFR,VEGFR,and mTOR,as well as immune checkpoint inhibitors(ICIs).Moreover,previous studies have identified mutations in CTNBB1,TP53,KDM5A,CENP-H,and other genes that may serve as therapeutic targets or biomarkers,thereby expanding the treatment options available for ACC.ICIs are effective against diverse cancer types,including non-small cell lung cancer(NSCLC),liver cancer,renal cell cancer,and urothelial cancer.Ongoing exploration into targeted therapies and immunotherapy,especially combination treatments,holds the promise of extending the survival of patients and enhancing their quality of life.

The incidence of osteoporotic thoracolumbar vertebral fracture (OTLVF) in the elderly is gradually increasing. The kyphotic deformity caused by various factors has become an important characteristic of OTLVF and has received increasing attention. Its clinical manifestations include pain, delayed nerve damage, sagittal imbalance, etc. Currently, the definition and diagnosis of OTLVF with kyphotic deformity in the elderly are still unclear. Although there are many treatment options, they are controversial. Existing guidelines or consensuses pay little attention to this type of fracture with kyphotic deformity. To this end, the Lumbar Education Working Group of the Spine Branch of the Chinese Medicine Education Association and Editorial Committee of Chinese Journal of Trauma organized the experts in the relevant fields to jointly develop Clinical guidelines for the diagnosis and treatment of osteoporotic thoracolumbar vertebral fractures with kyphotic deformity in the elderly ( version 2024), based on evidence-based medical advancements and the principles of scientificity, practicality, and advanced nature, which provided 18 recommendations to standardize the clinical diagnosis and treatment.

Objective:To investigate the 10-years risk for cardiovascular diseases(CVD) among different subtypes of pre-diabetes(Pre-DM) residents aged 40 and above in Guiyang urban area and to analyze the influencing factors.Methods:A total of 5 798 residents who participated in the " Risk Evaluation of cAncers in Chinese diabe Tic Individuals: a lONgitudinal(REACTION) Study" were selected to undergo oral glucose tolerance test and glycated hemoglobin test. According to the Pre-DM diagnostic criteria, normal glucose tolerance(NGT), impaired fasting glucose(IFG), impaired glucose tolerance(IGT), and diabetes mellitus were defined based on glycated hemoglobin(IA1C), and were combined into four groups: NGT group, single subtype group(IFG, IGT, IA1C), two-subtype combination group(IFG+ IGT, IFG+ IA1C, IGT+ IA1C), and three-subtype combination group(IFG+ IGT+ IA1C). Ten-year cardiovascular disease occurrence was investigated. The logistic regression model was used to analyze the risk of CVD occurrence in different subtypes of Pre-DM residents. Results:(1)The incidence in the single subtype group, two subtypes group and three subtypes group of CVD was 6.6%(182/2 752), 8.4%(135/1 613) and 9.6%(53/551) , respectively, all higher than NGT group at 5.2%(46/882). (2) Regardless of diagnosed by fasting blood glucose, 2 h blood glucose, or glycated hemoglobin, the 10-year CVD incidence rates(8.7%, 8.6%, 7.6%) in Pre-DM were higher than that in the NGT group(5.2%; all P<0.05). (3)After multivariate adjustment, compared with the NGT group, the 10-year CVD risk gradually increased in the single subtype group, two-subtype group, and three-subtype group, with OR of 1.03(95% CI 0.74-1.45), 1.08(95% CI 0.75-1.54), and 1.16(95% CI 0.75-1.78), respectively. Conclusion:The Pre-DM population has a higher 10-year risk for CVD, and the risk increases gradually with the accumulation of subtypes. Therefore the prevention and treatment of CVD should focus on the management of the Pre-DM population.

Objective:To explore whether metabolically healthy obesity(MHO) is a healthy state by observing the incidence of metabolic syndrome(MS) including its components and cardiovascular disease(CVD) in this population.Methods:In 2011, a cohort of 10 140 residents aged 40-79 years old was selected with cluster sampling in the Guiyang urban area. Fasting plasma glucose(FPG), blood lipids, and blood pressure were examined to assess their metabolic status. Height and weight were also measured. Among them, 1 299 metabolically healthy subjects were divided into 3 groups according to body mass index, namely metabolically healthy normal weight(MHNW), metabolically healthy overweight(MHOW), and MHO. Three groups were reassembled in 2014, and finally a total of 966 subjects with baseline and complete follow-up data were included in the analysis. The relationship between MS and its components, and the incidence of CVD were compared among the three groups.Results:(1) After an average follow-up of 3 years, 47.77% of the MHO population transformed into a metabolically unhealthy state. There was no significant difference in the incidence of MS components among the three groups( P>0.05), but there was a significant difference in the incidence of MS( P<0.05); (2) There was no significant difference in the incidence of CVD among the three groups after 3 years of follow-up. Logistic regression was used to analyze the risk factors of CVD in the three groups. Taking the MHNW as the control group, after adjusting for age, gender, FPG, blood lipids, and blood pressure, the risk ratio of the MHOW group was 0.941(0.661-1.202), and MHO group was 0.974(0.702-1.291). Conclusions:After 3 years of follow-up, although the risk of CVD in the MHO population did not increase significantly, the incidences of MS, triglycerides, and FPG abnormality increased compared with the normal people, suggesting that the MHO is not a " stable" healthy state.

Objective:To investigate the effect of the interaction between metabolic syndrome and smoking on the risk of subsequent cardiovascular events.Methods:Urban residents aged 40 and above in the Yunyan District of Guiyang City were selected from " Risk Evaluation of cAncers in Chinese diabeTic Individuals: A lONgitudinal(REACTION) Study". The baseline survey started in 2011 and general information including gender, age, medical history, lifestyle habits, and smoking status were collected. Additionally, biochemical indicators related to metabolic syndrome(MS) were measured. The study participants were then followed up, and the first cardiovascular events occurring after the initial survey were recorded. The average follow-up period was 10.07±1.49 years. The interaction between metabolic syndrome and smoking on subsequent cardiovascular events was analyzed using Cox proportional hazards models.Results:The study included a total of 7 275 individuals, among whom 639 experienced cardiovascular events. After adjusting for multiple variables, compared to non-smokers without metabolic syndrome(MS), smokers with MS showed a higher risk of cardiovascular events, with a hazard ratio( HR) of 6.54(95% CI 4.88, 8.78). This risk was higher than that of individuals with MS who never smoked [ HR 1.39(95% CI 1.11, 1.75)] and non-MS smokers [ HR 2.48(95% CI 1.77, 3.49)]. There was an additive interaction between MS and smoking on the occurrence of cardiovascular events, with a relative excess risk due to interaction(RERI) of 3.30(95% CI 1.89, 4.70), an attributable proportion(AP) of 0.55(95% CI 0.43, 0.59), and a synergy index(S) of 3.07(95% CI 1.94, 4.84). Furthermore, when stratifying the duration of smoking cessation, long-term quitters(≥8 years) showed a lower risk of cardiovascular events compared to current smokers, regardless of whether they had MS. The hazard ratios were 0.45(95% CI 0.26, 0.78) for individuals with MS and 0.42(95% CI 0.19, 0.95) for individuals without MS. Conclusions:There is an additive interaction between smoking and MS on the risk of cardiovascular events. The coexistence of both factors significantly increases the risk of cardiovascular events.

Objective:Explore the relationship between sleep duration, sleep time and brachial-ankle pulse wave velocity(baPWV) in community population.Methods:Questionnaire, physical examination, blood tests, and baPWV detection were applied to a community based population. Finally, 3 912 subjects with complete data were included in the study. The relationship between sleep duration, time to fall asleep and PWV was evaluated with binary logistic regression analysis. Results:Being adjusted for age, sex, prevalence of diabetes, sleep condition, body mass index, blood glucose, blood pressure, dyslipidemia, ankle-brachial index, sleep duration and time to fall asleep were correlated with PWV. The risk of PWV abnormalities was increased in the≥8 h group compared to the 6-8 h group( OR=1.155, 95% CI 0.995-1.367, P=0.037). The risk of abnormalities PWV was higher in the group with sleep time after 00: 00 than in the group -23: 00( OR=1.482, 95% CI 1.008-2.179, P=0.045). Conclusion:Long sleep duration(≥8 h) and late sleep time(after 00: 00) may be associated with higher risk of atherosclerosis.
