Objective To investigate the trends in the global burden due to cystic echinococcosis from 1990 to 2021, and to predict the global burden of cystic echinococcosis from 2022 to 2035, so as to provide insights into formulation of the cystic echinococcosis control strategy. Methods The global age-standardized prevalence, mortality, disability-adjusted life years (DALYs) rates and their 95% uncertainty intervals (UI) of cystic echinococcosis from 1990 to 2021 were captured from the Global Burden of Disease Study 2021 (GBD 2021) database, and the trends in the global burden of cystic echinococcosis from 1990 to 2021 were analyzed using the Joinpoint regression model. The associations between the global burden of cystic echinococcosis and socio-demographic index (SDI) were examined using a smoothing spline model and frontier analysis, and the global burden of cystic echinococcosis was projected from 2022 to 2035 using the Bayesian age-period-cohort (BAPC) model. Results The global agestandardized prevalence, mortality and DALYs rates of cystic echinococcosis were 7.69/10⁵ [95% UI: (6.27/10⁵, 9.51/10⁵)], 0.02/10⁵ [95% UI: (0.01/10⁵, 0.02/10⁵)], and 1.32/10⁵ [95% UI: (0.99/10⁵, 1.69/10⁵)] in 2021. The global age-standardized prevalence of cystic echinococcosis appeared a tendency towards a rise by 0.14% per year from 1990 to 2021, and the global age-standardized mortality and DALYs rates of cystic echinococcosis appeared a tendency towards a decline by 4.68% and 4.01% per year from 1990 to 2021, respectively. Joinpoint regression analysis showed that global age-standardized prevalence of cystic echinococcosis appeared a tendency towards a decline from 1990 to 2000 [annual percent change (APC) = −0.66%, 95% confidence interval (CI): (−0.70%, −0.61%)] and from 2005 to 2015 [APC = −0.88%, 95% CI: (−0.93%, −0.82%)], and towards a rise from 2000 to 2005 [APC = 3.68%, 95% CI: (3.49%, 3.87%)] and from 2015 to 2021 [APC=0.30%, 95%CI: (0.19%, 0.40%)].Theagestandardized prevalence (r = −0.17, P < 0.05), mortality (r = −0.67, P < 0.05) and DALYs rates of cystic echinococcosis (r = −0.60, P < 0.05) all correlated negatively with SDI across 21 geographical regions from 1990 to 2021, and the age-standardized mortality (r = −0.61, P < 0.05) and DALYs rates (r = −0.44, P < 0.05) both correlated negatively with SDI across 204 countries and territories in 2021. Frontier analysis revealed that the age-standardized DALYs rate of cystic echinococcosis was still not in line with the frontier in some high-SDI countries or territories. In addition, the global age-standardized prevalence was projected with the BAPC model to appear a tendency towards a rise among both men [estimated annual percent change (EAPC) = 0.18%, 95% CI: (0.13%, 0.23%)] and women [EAPC = 0.29%, 95% CI: (0.24%, 0.34%)] from 2022 to 2035, and the global age-standardized mortality [men: EAPC = −4.71%, 95% CI: (−4.71%, −4.37%); women: EAPC = −4.74%, 95% CI: (−4.74%, −4.74%)] and DALYs rates [men: EAPC = −3.35%, 95% CI: (−3.36%, −3.34%); women: EAPC = −3.17%, 95% CI: (−3.18%, −3.16%)] were projected to appear a tendency towards a decline among both men and women. Conclusions The global burden of cystic echinococcosis appeared an overall tendency towards a decline from 1990 to 2021; however, the global prevalence of cystic echinococcosis is projected to appear a tendency towards a rise from 2022 to 2035. Intensified cystic echinococcosis control programmes are recommended.

Objective:To explore the inhibitory effect of curcumin on the malignant biological behavior of uveal melanoma (UM) and its possible mechanism.Methods:M23 cells were cultured in curcumin medium with different concentrations (0, 20, 40 and 80 μmol/L) for 48 hours, respectively.The morphological changes of cells were observed under an inverted microscope.The cell survival rate was detected by the cell counting kit-8 (CCK-8) method.The apoptosis, colony formation, migration and invasion of cells were detected by flow cytometry, plate clone formation experiment, cell scratch experiment and Transwell assay, respectively.The relative expressions of genes related to Wnt/β-catenin pathway, c-Myc, Cyclin D1, Survivin and matrix metallo proteinase 9 ( MMP-9) mRNA in cells were detected by real-time fluorescence quantitative PCR.The relative expressions of proteins related to Wnt/β-catenin pathway, c-Myc, Cyclin D1, Survivin, MMP-9 and β-catenin, glycogen synthase kinase 3β (GSK-3β), phosphorylated GSK-3β (p-GSK-3β) and axis inhibition protein 2 (Axin2) proteins were detected by Western blot.Another 20 female BALB/c mice were selected and injected with M23 cell suspension under the subcutaneous fat pad in the left posterior abdomen to establish the in vivo M23 transplanted tumor model.The mice successfully modeled were randomly divided into model group, low-dose curcumin group, medium-dose curcumin group and high-dose curcumin group according to the random number table method, which was intraperitoneally injected with 0, 10, 20 and 40 mg/kg curcumin physiological saline solution respectively.After a continuous injection for 30 days, the subcutaneous tumor was stripped and weighed.The animal experiment process followed the 3Rs principle of animal research and was approved by the Laboratory Animal Ethics Committee of Inner Mongolia Baotou Steel Hospital (No.2021MER-023). Results:The cell survival rate, the number of colony formation, the apoptosis rate, the cell invasion rate and the cell migration rate were (100.00±0.00)%, 128.67±9.18, (1.33±0.29)%, (89.76±4.57)% and 148.33±8.18 in 0 μmol/L curcumin group, (83.78±4.59)%, 100.33±8.73, (14.53±2.04)%, (65.43±3.70)% and 125.33±7.41 in 20 μmol/L curcumin group, (66.09±3.92)%, 58.67±6.55, (27.23±3.56)%, (34.83±2.19)% and 73.67±6.34 in 40 μmol/L curcumin group, and (47.16±3.63)%, 31.67±4.92, (44.73±4.36)%, (18.82±1.99)% and 45.67±5.31 in 80 μmol/L curcumin group.There were statistically significant differences in the survival rate, colony formation number, cell apoptosis rate, migration rate and invasion rate of M23 cells among the four groups ( F=125.321, 97.941, 72.516, 277.097, 139.006; all at P<0.001). With the increase of curcumin concentration, the cell survival rate, colony formation number, cell migration rate and cell invasion number decreased obviously, and the cell apoptosis rate increased obviously, and the pairwise comparisons showed significant differences (all at P<0.05). With the increase of curcumin concentration, the relative expression levels of c-Myc, Cyclin D1, Survivin, MMP-9 mRNA and proteins, β-catenin and p-GSK-3β proteins decreased significantly, while the relative expression level of Axin2 protein increased significantly, showing significant differences in pairwise comparisons (all at P<0.05). The tumor tissue weight of mice decreased with the increase of curcumin dosage, and the pairwise comparisons were statistically significant (all at P<0.05). Conclusions:Curcumin can inhibit the proliferation, migration, invasion and other malignant biological behaviors of UM M23 cells, inhibit tumor growth and promote cell apoptosis.Its mechanism may be related to blocking the activation of Wnt/β-catenin pathway.

Objective To understand the current status and influencing factors of patient perception for humanistic care in China hospitals,and to provide a basis for developing nursing humanistic care measures and improving the quality of nursing humanistic care services.Methods A total of 30,099 outpatients and inpatients from 107 hospitals in 30 provinces(autonomous regions and municipalities)from July to August 2022 as survey subjects.A general information questionnaire and the Relational Caring Questionnaire-Patient Form were used for a cross-sectional survey,and a single-factor analysis was used to analyze the influencing factors of patient relationship care.Results Finally,29 108 valid questionnaires were collected,and the effective questionnaire recovery rate was 96.7％.The patient evaluation of relationship care was(65.72±8.61)points.Single-factor analysis showed that gender,age,marital status,children's situation,education level,occupation,place of residence,average family income,medical insurance type,visiting department,and location of the visiting hospital,and whether or not surgery were influencing factors of patient relationship care(P＜0.05).Conclusion The evaluation score of caregiver-patient relationship care among Chinese hospital patients is above average,but there is still room for improvement in western and rural regions,seriously ill and outpatient patients,low-income and low-medical insurance reimbursement populations,and non-surgical patients.Medical institutions at all levels should optimize and improve nursing humanistic care services based on influencing factors,and further enhance patients'perception of nursing humanistic care.

BACKGROUND:Observational studies have suggested that statin drugs may have a protective effect on bone density,making them a potential treatment option for osteoporosis. OBJECTIVE:To evaluate the causal relationship between drug target-mediated lipid phenotypes and bone mineral density(BMD)using Mendelian randomization methods. METHODS:We obtained single nucleotide polymorphismsrelated to statin drugs and BMD data from the IEU Open GWAS database.The primary analysis method was the inverse variance weighted method,and we also used weighted median,simple median,weighted mode,and MR-Egger regression.We usedβ values and 95%confidence intervals(CI)to assess the causal relationship between statin drugs and BMD.Additionally,we conducted sensitivity analyses to validate the results,assessed heterogeneity using Cochran's Q test,examined for horizontal pleiotropy using the MR-Egger intercept test,and performed leave-one-out analyses to determine if individual or multiplesingle nucleotide polymorphism influenced the results. RESULTS AND CONCLUSION:There was a significant association between the statin target of action,3-hydroxy-3-methyl glutaryl coenzyme A reductase-mediated low-density lipoprotein cholesterol,and heel bone BMD(β=-0.086,95%CI:-0.117 to-0.055,P=5.42×10-8)and whole-body BMD(β=-0.193,95%CI:-0.288 to-0.098,P=7.35×10-5).The findings of this study support the protective effect of statin drugs on BMD.These findings not only deepen our understanding of the relationship between cholesterol-related genes and bone health but also reveal potential therapeutic targets for improving BMD.

Recently,adeno-associated virus(AAV)vectors have been a hotspot in gene therapy and have shown great potential for rare diseases therapy,due to their low pathogenicity,mild immunogenicity and high tissue specificity.The safety and efficacy of AAV vectors,which are essentially infectious viruses,require new bioanalytical techniques to assess.At present,the relevant industry guidelines have specified the needs for the assessment of biodistribution,shedding,and immunogenicity,but the requirements related to bioassay are limited.In this paper,we reviewed the bioanalytical techniques and pharmacokinetics/pharmacodynamics(PK/PD)research of AAV vectors and their challenges from four aspects:biodistribution,shedding,immunogenicity and PK/PD research,with the hope of providing some reference for the clinical development of AAV vectors gene therapy products.

Objective:To investigate the clinicopathological features and molecular characteristics of β-catenin-deficient colorectal cancer.Methods:The clinical, pathological and molecular features of 11 colorectal cancers with β-catenin protein loss diagnosed at the 960th Hospital of People′s Liberation Army of China, from January 2012 to November 2022 were analyzed.Results:Among the 11 patients, 3 were males and 8 were females. Their age ranged from 43 to 74 years, with the median age of 59 years. Six were in the left colon and 5 were in the right colon. One of the 11 cases had lymph node metastasis, 10 cases were well and moderately differentiated adenocarcinoma, and 1 was mucinous adenocarcinoma. Eight cases were of TNM stage T4, 2 of T1 stage and 1 of Tis stage. β-catenin protein was not detected using immunohistochemistry. Sanger sequencing revealed the presence of fragment-deletion mutation in exon 3 of CTNNB1 gene, resulting in loss of β-catenin protein expression.Conclusion:β-catenin deficiency is present in a small number of colorectal cancers and may be associated with exon 3 mutations of CTNNB1 gene.

Objective:To evaluate the diagnostic efficacy and practicality of the Jaundice color card (JCard) as a screening tool for neonatal jaundice.Methods:Following the standards for reporting of diagnostic accuracy studies (STARD) statement, a multicenter prospective study was conducted in 9 hospitals in China from October 2019 to September 2021. A total of 845 newborns who were admitted to the hospital or outpatient department for liver function testing due to their own diseases. The inclusion criteria were a gestational age of ≥35 weeks, a birth weight of ≥2 000 g, and an age of ≤28 days. The neonate′s parents used the JCard to measure jaundice at the neonate′s cheek. Within 2 hours of the JCard measurement, transcutaneous bilirubin (TcB) was measured with a JH20-1B device and total serum bilirubin (TSB) was detected. The Pearson′s correlation analysis, Bland-Altman plots and the receiver operating characteristic (ROC) curve were used for statistic analysis.Results:Out of the 854 newborns, 445 were male and 409 were female; 46 were born at 35-36 weeks of gestational age and 808 were born at ≥37 weeks of gestational age. Additionally, 432 cases were aged 0-3 days, 236 cases were aged 4-7 days, and 186 cases were aged 8-28 days. The TSB level was (227.4±89.6) μmol/L, with a range of 23.7-717.0 μmol/L. The JCard level was (221.4±77.0) μmol/L and the TcB level was (252.5±76.0) μmol/L. Both the JCard and TcB values showed good correlation ( r=0.77 and 0.80, respectively) and agreements (96.0% (820/854) and 95.2% (813/854) of samples fell within the 95% limits of agreement, respectively) with TSB. The JCard value of 12 had a sensitivity of 0.93 and specificity of 0.75 for identifying a TSB ≥205.2?μmol/L, and a sensitivity of 1.00 and specificity of 0.35 for identifying a TSB ≥342.0?μmol/L. The TcB value of 205.2?μmol/L had a sensitivity of 0.97 and specificity of 0.60 for identifying TSB levels of 205.2 μmol/L, and a sensitivity of 1.00 and specificity of 0.26 for identifying TSB levels of 342.0 μmol/L. The areas under the ROC curve (AUC) of JCard for identifying TSB levels of 153.9, 205.2, 256.5, and 342.0 μmol/L were 0.96, 0.92, 0.83, and 0.83, respectively. The AUC of TcB were 0.94, 0.91, 0.86, and 0.87, respectively. There were both no significant differences between the AUC of JCard and TcB in identifying TSB levels of 153.9 and 205.2 μmol/L (both P>0.05). However, the AUC of JCard were both lower than those of TcB in identifying TSB levels of 256.5 and 342.0 μmol/L (both P<0.05). Conclusions:JCard can be used to classify different levels of bilirubin, but its diagnostic efficacy decreases with increasing bilirubin levels. When TSB level are ≤205.2 μmol/L, its diagnostic efficacy is equivalent to that of the JH20-1B. To prevent the misdiagnosis of severe jaundice, it is recommended that parents use a low JCard score, such as 12, to identify severe hyperbilirubinemia (TSB ≥342.0 μmol/L).

Patients with severe trauma require an extremely timely treatment and transfusion plays an irreplaceable role in the emergency treatment of such patients. An increasing number of evidence-based medicinal evidences and clinical practices suggest that patients with severe traumatic bleeding benefit from early transfusion of low-titer group O whole blood or hemostatic resuscitation with red blood cells, plasma and platelet of a balanced ratio. However, the current domestic mode of blood supply cannot fully meet the requirements of timely and effective blood transfusion for emergency treatment of patients with severe trauma in clinical practice. In order to solve the key problems in blood supply and blood transfusion strategies for emergency treatment of severe trauma, Branch of Clinical Transfusion Medicine of Chinese Medical Association, Group for Trauma Emergency Care and Multiple Injuries of Trauma Branch of Chinese Medical Association, Young Scholar Group of Disaster Medicine Branch of Chinese Medical Association organized domestic experts of blood transfusion medicine and trauma treatment to jointly formulate Chinese expert consensus on blood support mode and blood transfusion strategies for emergency treatment of severe trauma patients ( version 2024). Based on the evidence-based medical evidence and Delphi method of expert consultation and voting, 10 recommendations were put forward from two aspects of blood support mode and transfusion strategies, aiming to provide a reference for transfusion resuscitation in the emergency treatment of severe trauma and further improve the success rate of treatment of patients with severe trauma.

Objective This study aims to investigate the application of symptom group management using a mo-bile health platform in managing heart failure patients during convalescence.Methods The research involved pa-tients with chronic heart failure who were treated at a tertiary A hospital in Qingdao from June 2022 to December 2022.The experimental group consisted of 235 patients who were discharged after treatment in ward A,while the control group consisted of 235 patients who were discharged during the same period in ward B.The experimental group received an mHealth-based symptom clusters management program following routine continuous nursing and the control group was given routine continuous nursing after discharge.6 months after the intervention,the heart function status,self-care level,and quality of life were compared between 2 groups.Results The experimental group ultimately included 232 cases,while the control group ultimately included 225 cases.Furthermore,the cardiac functional status,level of self-care,and quality of life of both the experimental group and the control group showed improvement compared to the pre-intervention period(P＜0.05).The experimental group exhibited significantly better cardiac function status compared to the control group,and the experimental group demonstrated higher levels of self-care confidence,and quality of life relative to the control group(P＜0.05).Conclusion The utilization of a mobile medical platform can enhance the management of heart failure patients'symptom groups,resulting in im-proved disease management efficiency.This platform provides patients with a comprehensive self-management plan,ultimately enhancing their self-management abilities and overall outcomes.

Objective To explore the mechanisms of Buyang Huanwu Decoction(BYHWD)in reducing oxidative stress levels to protect the blood-brain barrier(BBB)in cerebral ischemia/reperfusion injury(CIRI)rats.Methods A middle cerebral artery occlusion/reperfusion(MCAO/R)model in rats was established via wire embolization method.PeriCam PSI laser speckle flow imaging was applied to detect whether the model was successfully established.Neurological deficits in the rats were evaluated by Zea Longa score,and histopathological changes in the rat brain were observed by HE staining.The degree of brain edema was detected by the dry and wet weight method.BBB permeability was detected by Evans blue staining,and ultrastructural changes to the BBB were observed by transmission electron microscopy.The levels of ROS,MDA and SOD activities,which are related to oxidative stress,were detected using kits.The expression levels of matrix metalloproteinase-9(MMP-9)were detected by immunohistochemical staining and Western blot.The expression levels of Occludin,ZO-1,and Claudin-5 tight junction proteins were determined via immunofluorescence and Western blot.Results BYHWD reduced neurological deficit scores,alleviated brain histopathological damage,alleviated BBB structural disruption,prolonged the appearance of dense regions in the tight junction structure,attenuated edema of the brain on the ischemic side,and reduced BBB permeability in MCAO/R rats.BYHWD decreased the levels of ROS and MDA,increased the activity of SOD,decreased the expression levels of MMP-9,and increased the expression levels of Occludin,Claudin-5 and ZO-1.Conclusions BYHWD can increase BBB tight junction protein expression levels,reduce the permeability of the BBB,protect the ultrastructure of the BBB,and reduce brain edema,and its mechanisms may be related to its antioxidant activity and inhibition of MMP-9 activation.
