ObjectiveTo investigate the role and possible mechanism of action of rhubarb decoction （RD） retention enema in improving inflammatory damage of brain tissue in a rat model of mild hepatic encephalopathy （MHE）. MethodsA total of 60 male Sprague-Dawley rats were divided into blank group （CON group with 6 rats） and chronic liver cirrhosis modeling group with 54 rats using the complete randomization method. After 12 weeks， 40 rats with successful modeling which were confirmed to meet the requirements for MHE model by the Morris water maze test were randomly divided into model group （MOD group）， lactulose group （LT group）， low-dose RD group （RD1 group）， middle-dose RD group （RD2 group）， and high-dose RD group （RD3 group）， with 8 rats in each group. The rats in the CON group and the MOD group were given retention enema with 2 mL of normal saline once a day； the rats in the LT group were given retention enema with 2 mL of lactulose at a dose of 22.5% once a day； the rats in the RD1， RD2， and RD3 groups were given retention enema with 2 mL RD at a dose of 2.5， 5.0， and 7.5 g/kg， respectively， once a day. After 10 days of treatment， the Morris water maze test was performed to analyze the spatial learning and memory abilities of rats. The rats were analyzed from the following aspects： behavioral status； the serum levels of alanine aminotransferase （ALT）， aspartate aminotransferase （AST）， interleukin-1β （IL-1β）， interleukin-6 （IL-6）， and tumor necrosis factor-α （TNF-α） and the level of blood ammonia； pathological changes of liver tissue and brain tissue； the mRNA and protein expression levels of phosphatidylinositol 3-kinase （PI3K）， protein kinase B （AKT）， and mammalian target of rapamycin （mTOR） in brain tissue. A one-way analysis of variance was used for comparison of continuous data between multiple groups， and the least significant difference t-test was used for further comparison between two groups. ResultsCompared with the MOD group， the RD1， RD2， and RD3 groups had a significantly shorter escape latency （all P<0.01）， significant reductions in the levels of ALT， AST， IL-1β， IL-6， TNF-α， and blood ammonia （all P<0.05）， significant alleviation of the degeneration， necrosis， and inflammation of hepatocytes and brain cells， and significant reductions in the mRNA and protein expression levels of PI3K， AKT， and mTOR in brain tissue （all P<0.05）， and the RD3 group had a better treatment outcome than the RD1 and RD2 groups. ConclusionRetention enema with RD can improve cognitive function and inflammatory damage of brain tissue in MHE rats， possibly by regulating the PI3K/AKT/mTOR signaling pathway.

Objectives:This study was designed to observe the impact of frailty status and multiple comorbidities on anticoagulation therapy adherence in elderly patients(≥75 years old)with atrial fibrillation. Methods:This retrospective study enrolled 528 patients(≥75 years old)with atrial fibrillation who were admitted to the geriatric department of Peking University Third Hospital from October 2016 to October 2019.A total of 443(83.9%)elderly patients receiving anticoagulation therapy were included,with an average age of(84.72±5.39)years.Thromboembolic and bleeding risk were evaluated by CHA2DS2-VASc and HAS-BLED,ATRIA bleeding score,while the frailty index(FI)and the age-adjusted Charlson comorbidity index(ACCI)were evaluated.Those with FI≥3 and FI between 1～2 were categorized into the frailty group and pre-frailty group.Patients with ACCI≥5 were defined as elderly multiple comorbidity group(high comorbidity burden).Patients who received anticoagulation therapy after discharge were followed up for one year in the outpatient clinic to observe their medication adherence and to find the related reasons. Results:Thromboembolic risk and bleeding scoring were performed in 443 elderly patients,with CHA2DS2-VASc and HAS-BLED scores of 5.61±1.57 and 3.08±0.89,respectively,and ATRIA score was 4.13±1.90.The FI assessment showed that all enrolled patients were in a state of frailty or pre-frailty.The average ACCI was 5.73±1.51.At one year of follow-up,96(21.67%)patients discontinued anticoagulation therapy.Frailty,high comorbidity burden,and high bleeding risk according to ATRIA(ATRIA≥5)were factors affecting medication adherence,with OR values of 1.114(95%CI:1.041-1.205,P=0.003),3.201(95%CI:2.126-4.509,P=0.001),and 1.457(95%CI:1.212-2.075,P=0.024),respectively.Considering non-death endpoint,both the HAS-BLED score(HAS-BLED≥3 分,OR=1.098,95%CI:1.035-1.116,P=0.014)and warfarin(OR=1.015,95%CI:1.001-1.030,P=0.040)were influential factors of medication compliance. Conclusions:The adherence to anticoagulation therapy post-discharge in elderly patients with atrial fibrillation is significantly influenced by frailty status and high comorbidity burden.If terms of non-death endpoint,high bleeding score and use of warfarin are influential factors of medication compliance.

Objective To analyze the effect of nursing interventions based on the Information-Motivation-Behavioral Skills (IMB) model in patients with functional dyspepsia, in order to improve their psychological state and gastrointestinal motility, and provide reference for clinical nursing. Methods A total of 160 functional dyspepsia patients admitted to the First Affiliated Hospital of Xinxiang Medical College from December 2022 to June 2023 were chosen as the study subjects. They were randomly divided into control group and observation group, using a random number table method, with 80 cases in each group. Patients in control group were given routine nursing intervention, and patients in the observation group were treated nursing intervention based on IMB model. The psychological state, gastrointestinal motility andquality of life of the two groups were compared before and after intezrvention. Results After intervention, the scores of Hamilton Anxiety Scale (HAMA) and Hamilton Depression Scale (HAMD) in two groups were decreased, and the observation group was lower than that in the control group (P < 0.05). After intervention, the levels of gastrointestinal hormone nitric oxide (NO), serum motilin (MTL) andserum gastrin (GAS) in two groups were improved, and the levels of all indexes in the observation group were better than those in the control group (P < 0.05). After intervention, gastrointestinal quality of life index (GIQLI) of two groups was improved, and the observation group was higher than the control group, the difference was statistically significant (P < 0.05). Conclusion Nursing interventions based on the IMB model are beneficial for alleviating anxiety and depression in patients with functional dyspepsia, effectively enhancing gastrointestinal motility and vitality, and improving their quality of life.

Background The burden of chronic kidney diseases (CKD) is continuously increasing in the globe. Environmental factors are one of the trigger factors for chronic kidney diseases of unknown etiology (CKDu). However, the current toxicological evidence on the renal effects induced by environmental high concentrations of multiple ions in drinking water and high temperature exposure is very limited. Objective To preliminary investigate the renal effects of exposure to drinking water with environmental high concentrations of fluoride, calcium, sodium, and bromide ions alone or in combination with high temperature in mice. Methods A mouse drinking water exposure model was established using ICR male mouse (8 weeks old) with exposure to 3 mg·L⁻¹ fluoride ions, 250 mg·L⁻¹ calcium ions, 400 mg·L⁻¹ sodium ions, and 1 mg·L⁻¹ bromide ions (to mimic the high concentration of ions in the groundwater in the areas with a high prevalence rate of CKDu in Sri Lanka) and high temperature of 32 ℃. ICR male mice were randomly divided into a mixed fluoride-calcium-sodium-bromide ion and high temperature exposure group, exposure groups of each ion and high temperature alone, a fluoride-calcium-sodium ion exposure group, and a fluoride-calcium-sodium-bromide ion exposure group. In the control group, the animals were given normal purified water at room temperature of (23±2) ℃. After 12 consecutive weeks of exposure, body weights and liver (kidney) organ coefficients were determined. Assessment of renal histopathologic damage was performed by hematoxylin-eosin staining and pathology scoring. At the end of the 12-week exposure period, 24 h urine samples were collected for the measurements of creatinine (UCr), albumin (ALB), neutrophil gelatinase-associated lipocalin (NGAL), and β2-microglobulin (β2-MG) levels. Cell apoptosis was assessed by TUNEL assay. Results The mice in the mixed exposure group showed a significant decrease in body weight and marked increases in the scores of renal histopathological injuries and the urinary levels of β2-MG compared to those of the control mice (P<0.05). Compared with the control group, the differences in body weight and urinary renal injury indexes of the mice in the fluoride-calcium-sodium and the fluoride-calcium-sodium-bromide ion groups (except for the decrease of the β2-MG levels in urinary in the latter group) were not statistically significant (P>0.05), but the renal histopathological injury scores were significantly increased (P<0.05). By contrast, body weights, liver (kidney) organ coefficient, and renal histopathological injury scores were comparable in the control mice and the mice fed with drinking water containing high levels of a single ion alone or housed at high temperature alone (P>0.05). Furthermore, the renal histopathological injury score showed no significant differences between the fluoride-calcium-sodium ion exposure group and the fluoride-calcium-sodium-bromide ion exposure group (P>0.05). The interaction between bromide ions and fluoride-calcium-sodium ions on renal tissue pathological damage was not statistically significant (P>0.05). Results from the TUNEL assay showed a significant increase in renal cell apoptosis in the fluoride-calcium-sodium ion exposure group (P<0.05). Conclusions Environmental high levels of mixed fluoride, calcium, and sodium ions in drinking water induce renal pathological damage in mice, which are exacerbated in combination with high temperature environment. High temperature exposure alone does not affect the pathological damage of renal tissue,

Objective To explore the application of patient empowerment in early rehabilitation training for patients with lower extremity deep vein thrombosis(DVT)after receiving catheter-directed thrombolysis(CDT).Methods A total of 110 patients with lower extremity DVT,who were scheduled for CDT therapy,were enrolled in this study.Using random digital table method,the patients were divided into control group(n=55)and intervention group(n=55).Routine rehabilitation activities were implemented for patients of the control group,while patient empowerment-based early rehabilitation training program was carried out for patients of the intervention group.The compliance to rehabilitation exercise,difference of upper/lower patella leg circumference,incidence of complications,duration of catheterization and thrombolysis,and length of hospital stay in both groups were calculated.The Self-Efficacy for Managing Chronic Disease,Chinese version of the Readiness for Hospital Discharge Scale,and the VEnous INsufficiency Epidemiological and Economic Study(VEINES)Quality of Life scale were used to evaluate the rehabilitation results of the patients of two groups.Results There were no significant differences in the duration of catheterization and thrombolysis,incidence of complications,and length of hospital stay between the two groups(all P＞0.05).At the time of discharge,the difference of upper/lower patella leg circumference in the intervention group was remarkably smaller than that in the control group,and the compliance with rehabilitation exercise,the self-efficacy,the readiness for discharge,and the quality of life in 3 months after discharge in the intervention group were strikingly better than those in the control group(all P＜0.05).Conclusion The implementation of patient empowerment in early rehabilitation training for patients with lower extremity DVT after receiving CDT therapy can improve the compliance with rehabilitation exercise,self-efficacy,limb swelling,readiness for discharge,and quality of life after discharge from hospital.(J Intervent Radiol,2024,33:554-559)

Objective:To understand the security status of newborn fathers and analyze its related factors.Methods:A total of 256 fathers(aged 22-49 years old)of newborns born within 1 week were select-ed.They were assessed with the self-designed general information questionnaire,Parents'Postnatal Sense of Securi-ty(father version),Emotional Inhibition Scale,and Marriage Satisfaction Subscale of Enrich Marital Inventory.Results:The average score of security was(36.0±4.4).Multiple linear regression analysis showed that the security scores were positively correlated with residence area(β=0.35),education level(β=0.25),preterm birth(β=0.11)and the marital satisfaction scores(β=0.25);and were negatively associated with daily crying time(β=-0.28)and the EIS scores(β=-0.18).Conclusion:The sense of security of postpartum fathers is moderate,and it is associated with residence area,education level,preterm birth,marital satisfaction,daily crying time and emotional inhibition.

Objective:To develop a standardized training model incorporating feedback from a digital assessment tool and to evaluate whether the model provides effective training in tooth preparation.Methods:The study was based on the training data of 53 trainees enrolled between February and June 2018 from multiple institutions in China. The trainees were trained in a standardized training unit on the preparation of right maxillary mesial incisors (11 #) for metal ceramic crowns. Three sessions of practice-assessment-feedback before examination were performed in one day. A digital assessment system was used to obtain total and component scores for the preparation as indicators of observation. The scores of three practice sessions and examination were subjected to analysis of variance. Results:The mean total scores before training, after the first training session, after the second training session, after the third training session, and in the examination were (60.53±12.73), (60.12±12.98), (71.25±13.70), (70.70±11.84), and (69.67±12.85), respectively; the overall difference was statistically significant ( F=19.06, P<0.001). Compared to the total scores before training and after the first training session, the total scores after the second and third training sessions and in the examination were significantly increased ( P<0.001, P<0.001). The score deductions for cutting amount and shoulder were similar, with overall significant differences (score deductions for cutting amount, F=16.20, P<0.001; score deductions for shoulder, F=1.45, P=0.032). Compared to before training and after the first training session, the second and third training sessions and the examination showed significant decreases in score deductions for cutting amount and shoulder ( P<0.001, P=0.048). Conclusions:The feedback-based standardized training process established on a digital evaluation system can rapidly enhance the skills of dentists in tooth preparation through immediate and effective feedback and targeted improvements. The training process enables an independent practice mode and optimizes teaching outcomes.
