PURPOSE: Coronary flow reserve (CFR) in the non-infarcted myocardium is often impaired following acute myocardial infarction (AMI). However, the clinical significance of CFR in the non-infarcted myocardium is not fully understood. The objective of the present study was to assess whether a relationship exists between CFR and left ventricular remodeling following AMI. MATERIALS AND METHODS: We enrolled 18 consecutive patients undergoing coronary intervention. Heart function was analyzed using real-time myocardial contrast echocardiography at one week and six months after coronary angioplasty. Ten subjects were enrolled as the control group and were examined using the same method at the same time to assess CFR. Cardiac troponin I (cTnI) levels were routinely analyzed to estimate peak concentration. RESULTS: CFR was 1.55+/-0.11 in the infarcted zone and 2.05+/-0.31 in the remote zone (p<0.01) at one week following AMI. According to CFR values in the remote zone, all patients were divided into two groups: Group I (CFR <2.05) and Group II (CFR >2.05). The levels of cTnI were higher in Group I compared to Group II on admission (36.40 vs. 21.38, p<0.05). Furthermore, left ventricular end diastolic volume was higher in Group I compared to Group II at six months following coronary angioplasty. CONCLUSION: Microvascular dysfunction is commonly observed in the remote myocardium. The CFR value accurately predicts adverse ventricular remodeling following AMI.

Objective:To analyze the predictive value of serological measures within 24 hours of admission in acute pancreatitis patients against patients with severe acute pancreatitis(SAP), because the severity of acute pancreatitis was characterized by a timely assessment and prediction by emergency department physicians upon visit.Methods:A total of 119 acute pancreatitis patients admitted in Emergency Department in Beijing Jishuitan Hospital, Capital Medical University from January 2022 to December 2022 were retrospectively collected. According to the revised Atlanta classification, patients were characterized by mild acute pancreatitis group (77 cases), moderately severe acute pancreatitis group (27 cases), and SAP group (15 cases). Basic characteristics, early disease severity scores and early serological indexes of the three groups were compared, independent risk factors of serological indexes affecting the occurrence of SAP were analyzed, and receiver operator characteristic curve was drawn, evaluate the predictive value of related serological indexes for SAP.Results:There were no significant differences in the basic characteristics of the three groups including of gender, age, BMI, type of pancreatitis and complications ( P>0.05), but there were significant differences in early BISPA, Ranson, APACHEⅡ and Panc3 scores among the three groups ( P<0.05).Albumin-bilirubin score ( OR=3.653, 95% CI 1.665-8.012, P=0.001), blood urea nitrogen ( OR=1.117, 95% CI 1.039-1.202, P=0.003) were independent risk factors for SAP. The areas under ROC curve predicted by albumin-bilirubin score, blood urea nitrogen and albumin-bilirubin score combined with blood urea nitrogen were 0.762, 0.776 and 0.857, respectively, which showed no statistical difference compared with earlier Ranson, BISAP and APACHE Ⅱ scoring systems, respectively ( P>0.05). Conclusions:Early albumin-bilirubin score and blood urea nitrogen indexes of acute pancreatitis patients have good predictive value for SAP. Albumin-bilirubin score combined with blood urea nitrogen can improve the predictive value of SAP, and the predictive effect is as good as early Ranson, BISAP and APACHEⅡ scoring systems.

Objective:To investigate the pathway of self-disclosure to posttraumatic growth in patients after cervical cancer surgery, and to provide reference for improving the level of posttraumatic growth in patients.Methods:A convenient sampling method was used to investigate 300 patients with cervical cancer after surgery in Shandong Provincial Hospital Affiliated to Shandong First Medical University from June to November 2022 by using general data questionnaire, Distress Disclosure Index (DDI), Connor-Davidson Resilience Scale (CD-RISC), the Shortened Chinese Version of the Family Resilience Assessment Scale (FRAS-C) and the Posttraumatic Growth Inventory (PTGI) in a cross-section study.Results:A total of 290 valid questionnaires were collected, with an effective recovery rate of 96.7%. The patients were aged 23-70(48.13 ± 10.39) years. The scores of self-disclosure, resilience, family resilience and posttraumatic growth were (46.41 ± 9.82), (67.06 ± 14.63), (108.18 ± 11.06) and (58.24 ± 17.86) respectively. The results of pathway analysis showed that self-disclosure could not only directly predict posttraumatic growth, but also indirectly predict posttraumatic growth through the mediating role of resilience and family resilience, and the chain mediating role of resilience and family resilience, respectively. The direct effect of self-disclosure on posttraumatic growth was 0.236(95% CI 0.138-0.335), and the chain mediating effect of family resilience and resilience between self-disclosure and posttraumatic growth was 0.036(95% CI 0.018-0.060). Conclusions:Medical staff should not only consider the direct influence of self-disclosure on posttraumatic growth, but also pay attention to improve the resilience and family flexibility of patients after cervical cancer surgery, so as to promote their posttraumatic growth.

Objective:To establishing a clinical prediction model can assist clinicians in identifying at-risk patients early and intervening promptly to decrease AUR incidence.Methods:A retrospective collection of 313 elderly patients with hip fracture treated between 1st July and 31st August 2023 at the Emergency Department of our hospital. Patients were categorised into two groups: The AUR group (45 patients) and the non-AUR group (268 patients) based on the presence or absence of AUR. Basic characteristics, laboratory indicators and bladder volume were compared between the two groups. Factors independently associated with the incidence of AUR were analysed using Logistic regression. Analysis of the independent risk factors impacting the occurrence of AUR, development of a clinical prediction model for the risk of AUR in elderly patients with hip fractures, and internal validation of the model.Results:Comorbid psycho-behavioural symptoms of dementia ( OR=3.334, 95% CI 1.258-8.839, P=0.015), use of hypnotic sedatives ( OR=6.758, 95% CI 2.184-20.912, P=0. 001), increased heart rate ( OR=1.041, 95% CI 1.013-1.070, P=0.004), and increased bladder volume ( OR=1.005, 95% CI 1.004-1.007, P<0.01) were all identified as risk factors. The study identified independent risk factors for AUR in elderly patients who suffered a hip fracture. Based on these factors, the research team developed a prediction model which underwent internal validation using the Bootstrap method. The analysis indicated that the model’s prediction curves aligned closely with the standard model curves. The average absolute error was 0.021. The study's ROC results showed an AUC of 0.083 and a 95% CI of 0.767-0.909. Conclusions:Comorbid psycho-behavioural symptoms of dementia, the use of hypnotic sedative drugs, an increased heart rate, and an increased bladder volume are independent risk factors for the occurrence of AUR in elderly patients who have suffered a hip fracture. The creation of a chart prediction model using columns allows for a visual evaluation of the likelihood of AUR in elderly patients with hip fractures. This model provides important reference material for emergency physicians.

Objective:To systematically evaluate the factors that promote and hinder exercise in patients with chronic kidney disease, and to provide reference for exercise intervention.Methods:The Cochrane Library,Web of Science, PubMed, Embase, CNKI, Wanfang, VIP and China Biomedical Literature Database were searched for qualitative researches on the promoting and hindering factors of exercise in patients with chronic kidney disease.The retrieval period was from the establishment of the database to January 2022. Qualitative Research Authenticity Evaluation Tool (version 2016) from JBI Evidence-Based Health Care Center was used to evaluate the quality of the literatures, and Meta-integration was used to analyze the results.Results:A total of 10 articles were included and 60 results were extracted, which were grouped into 8 new categories and integrated into 2 results:the promoting factors included personal exercise motivation,exercise self-efficacy stimulation,physical and psychological benefits and good social support;the hindering factors included disease and treatment factors,low exercise self-efficacy,fear of exercise risk and weak social support.Conclusions:Exercise of patients with chronic kidney disease is affected by many factors, so we should deeply understand the actual situation of patients,pay attention to the core factors affecting exercise, and improve the health of patients.

Objective To analyze the outcome indexes selected in the randomized controlled trials(RCTs)on traditional Chinese medicine(TCM)for skin rash caused by EGFR-TKI.Methods Seven databases were researched and the literature was screened according to the inclusion and exclusion criteria,then summarize and categorize outcome indexes to calculate frequency of outcomes and analyze.Results 46 out of 2241 papers were included.The outcome indexes of 40 RCTs were mainly divided into seven categories,that is physical symptoms/signs(37.97%),quality of life(17.65%),safety indicators(13.37%),traditional Chinese medicine symptoms/syndromes(16.58%),long-term prognosis(1.60%),blood biochemical index(9.09%)and others(3.74%).Problems as follow:First,there is a high risk of clinical trial bias in the treatment of EGFR-TKI-associated rash with TCM.Besides,the measurement time points was largely different with the severity of rash not considered.What's more,oversimplify the reports of compound outcome indicators and safety evaluation,lack of treatment time window and full process observation.Last,grading criteria for rash were inconsistent and the function of quality of life assessment tool was relatively simple.Conclusion At present,the use of outcome indicators has not been standardized in the RCTs for skin rash related EGFR-TKI by TCM,and relevant construction work should be carried out in the future to build a core index set with the characteristics of TCM treatment.

Lung cancer is the malignant tumor with the highest incidence and mortality among the Chinese.Tumor node metastasis(TNM)staging established by the American Joint Committee on Cancer(AJCC)and International Union Against Cancer(UICC)is a commonly used criterion,but it still has limitations in judging the prognosis of non-small cell lung cancer(NSCLC)patients.With the advantages of real-time and convenient sampling,the immune score based on peripheral blood biomarkers have the ability to predict prognosis and efficacy of NSCLC patients,which have been developed and validated in clinical studies.However,clinical impleruentation of peripheral immune scores is still not widely in NSCLC patients.Therefore,this study introduces and evaluates the 6 peripheral immune scores and reviews the reseach progress of them in the treatment of NSCLC.

Objective:To investigate the application value of nectin-4 targeting radiotracer 68Ga-N188 in the diagnosis of pancreatic cancer. Methods:The prospective study was conducted. The clinicopathologic data of 16 patients diagnosed as pancreatic cancer on enhanced computed tomography (CT) who were admitted to the Peking University First Hospital from August to December 2022 were collected. There were 9 males and 7 females, aged (62±8)years. All patients underwent 18F-flurodeoxyglucose ( 18F-FDG) and 68Ga-N188 positron emission tomography (PET)/CT examination. Observation indicators: (1) distribution of 68Ga-N188 in different tissues and tumor primary lesion of patients; (2) expression of Nectin-4 and uptake of 68Ga-N188 in pancreatic cancer; (3) comparison of examination results between 68Ga-N188 and 18F-FDG PET/CT. Measurement data with normal distribution were represented as Mean± SD, and comparison between groups was conducted using the independent sample t test. Count data were described as absolute numbers or percentages. Results:(1) Distribution of 68Ga-N188 in different tissues and tumor primary lesion of patients. Results of PET/CT examination showed that in 1 hour after injection, the maximum standard uptake value (SUVmax) and mean standard uptake value (SUVmean) of 68Ga-N188 in fat, muscle, skin, and brain tissues of 16 patients were 0.40±0.16 and 0.25±0.09, 0.68±0.20 and 0.44±0.12, 0.39±0.14 and 0.28±0.11, 0.09±0.04 and 0.05±0.02, respectively. In the tissues of the esophagus, liver, spleen, and pancreas, the above indicators were 1.53±0.48 and 1.16±0.31, 1.49±0.45 and 0.91±0.30, 1.40±0.30 and 1.02±0.24, 1.24±0.31 and 0.96±0.25, respectively. In tumor primary lesion, the above indicators were 3.28±1.02 and 2.14±0.62, respectively, showing significant differences in SUVmax and SUVmean compared with pancreatic tissue ( t=8.03, 6.75, P<0.05). The tumor background ratio in tumor primary lesion based on SUVmax was 1.82±0.58. (2) Expression of Nectin-4 and uptake of 68Ga-N188 in pancreatic cancer. Results of immunohistochemical staining in 16 patients showed that there were 7 patients with high Nectin-4 expression and 9 patients with low Nectin-4 expression. Results of PET/CT examination showed that the SUVmax of 68Ga-N188 in tumor primary lesion of the 7 patients with high Nectin-4 expression and 9 patients with low Nectin-4 expression were 3.77±1.10 and 2.64±0.68, showing a significant difference between them ( t=2.64, P<0.05). The SUVmax of 18F-FDG in tumor primary lesion of the 7 patients with high Nectin-4 expression and 9 patients with low Nectin-4 expression were 6.73±3.24 and 6.43±3.45, showing no significant difference between them ( t=0.17, P>0.05). (3) Comparison of examination results between 68Ga-N188 and 18F-FDG PET/CT. Of the 16 patients, cases with positive results of tumor primary lesion on 68Ga-N188 and 18F-FDG PET/CT were 14 and 11, respectively, for the 14 pancreatic cancer patients diagnosed by postoperative histopathology. Among them, cases with positive results of tumor primary lesion on 68Ga-N188 and 18F-FDG PET/CT were 3 and 1 for the 3 pancreatic cancer patients receiving evaluation for chemotherapy. The SUVmax of 18F-FDG in tumor primary lesion of the 3 patients with chemotherapy and the 11 patients without chemotherapy were 2.80±0.69 and 6.97±2.11, showing a significant difference between them ( t=3.29, P<0.05). The SUVmax of 68Ga-N188 in tumor primary lesion of the 3 patients with chemotherapy and the 11 patients without chemotherapy were 3.38±1.12 and 2.93±0.50, showing no significant difference between them ( t=0.66, P>0.05). Cases with positive results of lymph node metastases in 68Ga-N188 and 18F-FDG PET/CT were 6 and 4, respectively, for the 6 pancreatic cancer patients diagnosed with lymph node metastases by postoperative histopathology, and the SUVmax of 68Ga-N188 and 18F-FDG in lymph node metastases were 2.25±1.12 and 4.02±1.27. Conclusion:68Ga-N188 PET/CT can be used for imaging diagnosis of tumor primary lesion and lymph node metastases of pancreatic cancer.

Objective:To build a systematic and standardized nutrition management plan for patients with chronic kidney disease.Methods:Based on the nutrition care procedure and model, a preliminary draft of a nutrition management plan for chronic kidney disease patients was developed through a literature search, quality evaluation, and group discussions. After two rounds of expert consultation and revision of the preliminary draft of the nutrition management plan, the final plan was formed.Results:A total of 32 experts were invited to complete two rounds of consultation.
