Objective·To investigate the safety and feasibility of early goal-directed mobilization in the recovery of gastrointestinal function after pancreaticoduodenectomy.Methods·The non-contemporaneous controlled studies were conducted.Subjects who underwent pancreaticoduodenectomy were included.From Sep 2022 to May 2023,forty patients were selected as the control group,and forty patients were selected from June 2023 to February 2024 as the experimental group.The general clinical data of the two groups were collected.The control group was treated with the nursing routine after pancreaticoduodenectomy,and there were no specific requirements for the time and goal of early activity.The experimental group had daily activity goals established for early mobilization,which were performed by the patients and their families,while the rest of their care was identical to that of the control group.The main index of effectiveness evaluation was the time of first flatus and first defecation,and the secondary indexes included the time of first getting out of bed,the time of oral drinking,the time of the gastric tube removal,and the postoperative levels of K+,Na+,and Cl-on the 3rd day of the postoperative period.Safety evaluations included chyle leak,postoperative pancreatic fistula,biliary leak and delayed gastric emptying,postoperative hemorrhage,unplanned reoperation,unplanned extubation,falls and death.Results·There was no statistically significant difference in the general clinical data of the patients in the 2 groups.After the implementation of early goal-directed mobilization,the time of first flatus was advanced from(3.95±1.68)d to(2.88±0.91)d(t=-3.560,P=0.001),and the time of first defecation was advanced from(4.90±1.61)d to(3.80±1.30)d(t=-3.352,P=0.001).The time of first getting out of bed was advanced from(5.18±1.77)d to(2.30±0.88)d(t=-9.205,P＜0.001),and the time of oral drinking was advanced from(4.10±1.89)d to(2.73±1.20)d(t=-3.883,P＜0.001).Significant differences were also observed in postoperative day 3 Na+(t=-2.745,P=0.008)and Cl-(t=-2.033,P=0.045)levels.Conclusion·Early goal-directed activity programs are safe and effective in promoting the recovery of gastrointestinal function after pancreaticoduodenectomy.

To deeply explore the load experience of primary caregivers of colorectal stoma patients, analyze their psychological load, understand their load experience when caring for patients, so as to provide theoretical basis for promoting patients’ home rehabilitation and continuous nursing. A semi-structured interview was conducted with the primary caregivers of 10 patients with permanent stoma in a tertiary hospital in Xi’an using a phenomenological research method, and the data were summarized and refined by Colaizzi 7-step analysis. A total of four themes were extracted: complex emotional reactions, lack of knowledge about stoma care, a huge care load on the shoulder, and social and financial support needed. The primary caregivers of colorectal stoma patients have a certain degree of care load in the daily care of the patients. Health care professionals should pay attention to the psycho-emotional changes of these individuals and take targeted interventions to reduce the psychological load of the caregivers and improve the quality of life of the patients and their caregivers.

Objective:To explore the effects of body mass index (BMI) on the incidence of nocturnal hypertension in patients with hypertension.Methods:Totally 341 hospitalized hypertensive patients treated at the Affiliated Hospital of Jining Medical University from February to May 2023 were selected by convenience sampling. Patients' general information, clinical data, and 24-hour ambulatory blood pressure results were collected. A binomial Logistic regression analysis was conducted to investigate the factors affecting the occurrence of nocturnal hypertension in these patients. The relationship between BMI and the incidence of nocturnal hypertension was examined using threshold effect tests and smooth curve fitting.Results:The binomial Logistic regression analysis indicated that blood phosphate level was a factor influencing the occurrence of nocturnal hypertension in hypertensive patients ( P<0.05). Smooth curve fitting and threshold effect test results showed that the relationship between BMI and the incidence of nocturnal hypertension was curve-correlated, with a turning point at 24.61 kg/m 2. To the left of the turning point, there was no correlation ( P=0.130) ; to the right, there was a correlation ( P=0.016) . Conclusions:When the BMI of hypertensive patients exceeds 24.61 kg/m 2, the likelihood of nocturnal hypertension increases with rising BMI, providing a precise intervention target for weight management-based patient care in hypertension.

Objective:To explore the status and influencing factors of positive feelings of caregivers of patients with enterostomy, so as to provide a reference for targeted interventions.Methods:From May to October 2021, convenience sampling was used to select 130 caregivers of patients with enterostomy who received follow-up visits in the Stoma Clinic of the First Affiliated Hospital of Xi'an Jiaotong University as the research subject. The survey was carried out using the General Information Questionnaire, the Positive Aspects of Caregiving (PAC) , and the Care Preparedness Scale (CPS) . A total of 130 questionnaires were distributed, and 127 valid questionnaires were recovered, with a valid recovery rate of 97.69%.Results:Among 127 caregivers of patients with enterostomy, the total score of PAC was (32.69±4.99) , and the self-affirmation dimension score was (18.39±2.84) , and the life outlook dimension score was (14.36±2.53) , and the total score of CPS was (17.76±4.36) . Multiple linear regression analysis showed that caregiver gender, education level, work status, and readiness were the influencing factors of positive feelings of caregivers of patients with enterostomy ( P<0.05) , which explained 43.7% of the total variance. Conclusions:The positive perception of caregivers of patients with enterostomy is at an upper-middle level. Nurses should formulate targeted humanistic care strategies according to the influencing factors, increase the positive feelings of caregivers, help patients adapt to the stoma as soon as possible, and then improve the quality of life of patients.

Objective To observe the effect of early enteral nutrition (EEN) on nutritional indicators and clinical outcomes in patients with severe heart failure undergoing mechanical ventilation. Methods Thirty-four patients with severe heart failure (grade Ⅲ-Ⅳ of cardiac function) and pulmonary infections undergoing mechanical ventilation admitted to intensive care unit (ICU) of Second Affiliated Hospital of Zhejiang University of Traditional Chinese Medicine from May 2017 to April 2018 were enrolled. They were randomly divided into EEN group and delayed enteral nutrition (DEN) group. Both groups were given routine treatment, including mechanical ventilation, improvement of cardiac function, anti-infection, protection of vital organ function, regulation of blood sugar and adjustment of electrolyte and acid-base balance. The patients in EEN group received enteral nutrition (EN) within 48 hours after ICU admission, and in DEN group, EN was started after the patients had spent the early stage of stress and had stable vital signs (48 hours after ICU admission). The changes in serum B-type natriuretic peptide (BNP), C-reactive protein (CRP), nutritional indicators and liver function indicators at ICU admission and 7 days after treatment were compared between the two groups. The time needed for patients to reach EN target, duration of mechanical ventilation, length of ICU stay, and the 28-day mortality were recorded, and complications were observed. Results There was no significant difference in serum BNP, CRP, nutritional indicators or liver function indicators at ICU admission between the two groups. After treatment for 7 days, BNP and CRP in both groups were decreased significantly as compared with those at ICU admission [BNP (ng/L): 592.1±370.9 vs. 2 517.7±1 163.4 in EEN group, 621.9±418.8 vs. 2 251.5±1 006.8 in DEN group; CRP (mg/L): 46.0±19.6 vs. 59.8±22.5 in EEN group, 40.5±18.8 vs. 61.2±24.6 in DEN group, all P < 0.05], pre-albumin (PA) and transferrin (TF) were significantly increased [PA (g/L): 0.18±0.05 vs. 0.15±0.06 in EEN group, 0.17±0.04 vs. 0.12±0.06 in DEN group; TF (g/L): 1.6±0.4 vs. 1.5±0.4 in EEN group, 1.7±0.5 vs. 1.4±0.5 in DEN group, all P < 0.05]. However, there was no significant difference in the above indicators after treatment between the two groups (all P > 0.05). There was no significant change in liver function after treatment in both groups. The EN treatment was successfully completed in both groups. Some patients developed abdominal distension and diarrhea in varying degrees, which were alleviated by slowing down the infusion rate, supplemented by gastrointestinal motility drugs and intestinal flora adjustment drugs. The time needed to reach EN target in EEN group was significantly earlier than that in DEN group (hours: 42.4±10.2 vs. 53.8±17.1, P < 0.05), the duration of mechanical ventilation (days: 14.2±8.7 vs. 13.4±7.9), the length of ICU stay (days: 17.8±6.7 vs. 18.3±5.6) and 28-day mortality [5.9% (1/17) vs. 11.8% (2/17)] showed no significant difference as compared with those in DEN group (all P > 0.05), and it did not increase the incidence of aspiration pneumonia [23.5% (4/17) vs. 17.7% (3/17), P > 0.05]. Conclusion EEN could help to achieve nutritional goals as soon as possible, improve the nutritional status of the body, and provide conditions and basis for further treatment of severe heart failure patients.

Gastric cancer is a malignant tumor characterized by high morbidity and mortality. With the development of molecular biol-ogy technology and the emergence of various new omics detection techniques in recent years, molecular epidemiologists of gastric cancer have conducted extensive studies on the genetic and host factors, as well as gene-environment interactions associated with ex-posure to environmental factors in gastric cancer. In addition, epidemiologists have studied the evolution of precancerous gastric le-sions, the development of gastric cancer, and explored relevant biomarkers to provide major evidence for the prevention and control of gastric cancer. This review summarizes the latest advances in the molecular epidemiology of gastric cancer, including existing evi-dence in studies for candidate-approach-based serum/plasma biomarkers, genome-wide association, whole-exome sequencing, tissue microarrays, as well as studies on metabolomics and microbiomes. We expect to provide insights into the future of molecular epidemi-ology studies in gastric cancer, promoting etiologic research, and the precise prevention and control of gastric cancer.

Objective To study the effects of mirabilite stuck on umbilical region combined with early enteral nutrition (EEN) on gastrointestinal function and serum inflammatory mediators in patients with mechanical ventilation. Methods Sixty-four patients with mechanical ventilation admitted to the Department of Intensive Care Unit of the Second Affiliated Hospital of Zhejiang Traditional Chinese Medical University from January to December 2016 were enrolled, and they were divided into an observation group and a control group by random number table, 32 cases in each group. The control group was treated with routine western medicine+ EEN, and the observation group was treated additionally with mirabilite stuck onto umbilical region on the basis of the treatment of the control group. The clinical effect was observed after 7 days of treatment. The differences in gastrointestinal function scores and the levels of serum inflammatory mediators were compared between the two groups before and after treatment.Results After treatment, gastrointestinal function scores of the diarrhea, bowel sound, abdominal distension and the levels of white blood cell count (WBC), serum procalcitonin (PCT), serum C-reactive protein (CRP) were decreased significantly in both groups compared with those before treatment, and the degrees of decreasing in above index levels after treatment in the observation group were more obvious than those in the control group [diarrhea: 0.72±0.03 vs. 1.59±0.21, bowel sounds: 0.87±0.05 vs. 1.54±0.18, abdominal distension: 0.77±0.04 vs. 1.63±0.09, WBC (×109/L): 9.87±1.25 vs. 12.46±2.04, PCT (μg/L): 5.43±1.02 vs. 9.65±1.63, CRP (mg/L): 56.87±4.52 vs. 89.43±8.24, allP < 0.05].Conclusion Applying mirabilite stuck on umbilical region combined with EEN can effectively promote the recovery of gastrointestinal function and significantly decrease the levels of serum inflammatory mediators in patients with mechanical ventilation.

Objective To observe the efficacy of antithrombotic treatment of acute ST-segment elevation myocardial infarction patients with failure primary percutaneous coronary intervention because of high thrombus burden,and its effect on elective percutaneous coronary intervention.Methods Eight acute ST-segment elevation myocardial infarction patients were enrolled,who suffered from failure of primary percutaneous coronary intervention because of high thrombus burden.Summarize the antithrombotic strategies in perioperative and postoperative period,the operative strategies and the follow-up coronary intervention were recorded and reviewed.Results All the patients were male and most of them had acute inferior myocardial infarction with right coronary occluded because of high thrombus burden.Four patients received thrombus aspiration and balloon dilation.One patient received thrombus aspiration and the other three patients did not receive coronary intervention.Tirofiban were given in perioperative period to all the patients.Low molecular weight heparin was given to 6 patients.Dual antiplatelet therapy was given to 6 patients (aspirin 100 mg/day plus clopidogrel 75 mg/day) and 1 patient required up-titration of aspirin to 200 mg/day.Coronary angiography were repeated (29.00 ± 23.25) days later,and the thrombus in the culprit vessels disappeared in two patients,and coronary stent implantation was performed in three patients.Conclusions The routine antithrombotic strategies play limited roles in thrombus clearance in acute ST segment elevation myocardial infarction patients with failure primary percutaneous coronary intervention because of high thrombus burden.The time for the thrombus to be totally organized and the timing of elective percutaneous coronary intervention are still uncertain and need to be further studied.

Aim To investigate the effect that catalpol intervenes macrophage polarization mediated by mouse mesangial cells(MMCs) stimulated by advanced glycation end products(AGEs).Methods RAW264.7 macrophages and MMCs were co-cultured in vitro and divided into model group(100 mg·L-1 AGEs), control group(100 mg·L-1 BSA), catalpol(0.1, 1.0, 10.0 μmol·L-1) group, and aminoguanidine(1.0 μmol·L-1) group which was set as positive control.After being incubated with catalpol for 1 h, MMCs were stimulated by AGEs for 23 h.The proliferation-inhibition rate of MMCs was measured by MTT assay.MCP-1 in supernatant liquid of MMCs was detected by ELISA method.The expression of iNOS, CD16/32, TNF-α, COX-2, CD206 and Arg-1 was detected by Western blot.Simultaneously, the percentage of iNOS and CD206 was also measured by flow cytometry.Results AGEs could increase the level of MCP-1 secreted by MMCs.The expression of iNOS, TNF-α, CD16/32 and COX-2 protein of macrophage was up-regulated after MMCs stimulated by AGEs, while the expression of CD206 and Arg-1 was down-regulated.After being intervened by catalpol, these effects could be reversed.All the changes were concentration-related.Conclusions Catalpol can inhibit macrophages M1-type polarization process and promote M2-type polarization, which may be mediated through MCP-1 secreted by MMCs after AGEs stimulation.Catalpol can ameliorate inflammation and relieve diabetic kidney injury.
