Objective? To investigate the dietary sodium intake level of patients with heart failure and analyze its influencing factors, so as to provide reference for formulating dietary intervention strategies for patients with heart failure. Methods? From July 2018 to April 2019, 153 patients with heart failure in the First Affiliated Hospital of Nanjing Medical University were selected as the subject by convenient sampling. The General Questionnaire and Dietary Sodium Restriction Questionnaire(DSRQ) were collected, and 24-hour urine sodium determination was used to assess the patient's dietary sodium intake level. Results? A total of 155 questionnaires were distributed and 153 questionnaires were returned. The average dietary sodium intake of 153 patients with heart failure was (3 725.39±1 741.84) mg/d. The dietary sodium intake of 24 patients was within the recommended range (2 000-3 000 mg/d), accounting for 15.7%(24/153). The total score of the DSRQ was (54.83±9.15), and the scores of attitude and subjective normative dimension, cognitive dimension and perceptual behavior control were (23.24±3.15), (11.77±2.08), and (19.82±6.13), respectively.Univariate analysis showed different genders, tastes, dental health status, and whether the dietary sodium intake was different for patients prescribed a low-sodium diet, the differences were statistically significant (P＜ 0.05);correlation analysis showed that appetite score and sodium intake in patients with heart failure was correlated, the difference was statistically significant (r=0.174, P=0.031), and the sodium-stable diet behavioral control score was associated with sodium intake in patients with heart failure (r=-0.329, P＜ 0.001). Multiple linear regression analysis showed that the patient's gender, taste, and patient's perceptual behavioral control of sodium-restricted diet were the main influencing factors of dietary sodium intake in patients with heart failure, explaining 21.5% of the total variation in dietary sodium intake. Conclusions? The dietary sodium intake of patients with heart failure is higher than the recommended amount of the guideline, and the current situation is not optimistic. In particular, health care workers should pay attention to individualized dietary guidance and interventions in men with low salty taste and low sodium-stable dietary behavioral scores to reduce heart failure and readmission rates.

Objective:To explore the effect of salt restriction strategy based on salt taste on salt taste preference (STP) and sodium intake in patients with chronic heart failure.Methods:From April to September 2020, convenience sampling was used to select 166 patients with chronic heart failure in the Cardiology Department of a Class Ⅲ Grade A hospital in Nanjing City, Jiangsu Province as the research object. The patients were randomly divided into the experimental group (83 cases) and the control group (83 cases) . Both groups of patients were given standardized chronic heart failure treatment methods and health education. On this basis, the experimental group was given a low-salt nutrient meal of 5.0g, 6.0g, and 7.5 g per day according to the different STP of the patients.The 24-hour urine sodium, STP, and Dietary Sodium Restriction Questionnaire (DSRQ) were used to evaluate the intervention effect.Results:After the intervention, there was a statistically significant difference in STP between the two groups of patients ( P<0.05) . The 24-hour urine sodium of the experimental group after intervention was lower than that of the control group, and the difference was statistically significant ( P<0.01) . After the intervention, the DSRQ score of the experimental group was higher than that of the control group, and the difference was statistically significant ( P<0.01) . Conclusions:The salt restriction strategy based on salt taste can reduce the STP and urine sodium of patients with chronic heart failure, and improve the current status of the implementation of sodium restriction diet.

Objective:To develop the Fecal Microbiota Transplantation Knowledge, Attitude, and Practice Scale for Patients with Inflammatory Bowel Disease (IBD), and test its reliability and validity.Methods:Guided by the theory of knowledge, attitude, and practice, a preliminary draft of the scale was formed through literature review, Delphi expert consultation, and pre-survey. From May to August 2022, convenience sampling was used to select 200 IBD patients who visited the Gastroenterology Clinic of three ClassⅢ Grade A comprehensive hospitals in Jiangsu Province as the research subject for a questionnaire survey. The critical ratio method, correlation analysis method, internal consistency method, commonality and factor loadings were used for item analysis of the scale. Exploratory factor analysis, content validity index, and internal consistency reliability were applied to test the reliability and validity of the scale.Results:A total of 200 questionnaires were distributed, and 181 valid questionnaires were collected, with an effective response rate of 90.50% (181/200). The Fecal Microbiota Transplantation Knowledge, Attitude, and Practice Scale for Patients with IBD included three dimensions of knowledge, attitude and practice, with a total of 21 items. The content validity index at the scale level was 0.917, and the content validity index at the item level ranged from 0.833 to 1.000. Exploratory factor analysis extracted three common factors, with a cumulative variance contribution rate of 74.197%. The Cronbach's α coefficient of the total scale was 0.951, and the coefficients of each dimension were 0.914 to 0.942. The test-retest reliability coefficient of the total scale was 0.918, and the test-retest reliability coefficients of each dimension ranged from 0.737 to 0.833.Conclusions:The Fecal Microbiota Transplantation Knowledge, Attitude, and Practice Scale for Patients with IBD has good reliability and validity, which can help medical and nursing staff evaluate patients' understanding and acceptance of microbial transplantation, so as to provide a basis for personalized communication in shared decision making between doctors and patients.

Purpose: This study aims to evaluate the efficacy and safety of a new combination treatment of vinorelbine and pyrotinib in human epidermal growth factor receptor 2 (HER2)–positive metastatic breast cancer (MBC) and provide higher level evidence for clinical practice. Materials and Methods: This was a prospective, single-arm, phase 2 trial conducted at three institutions in China. Patients with HER2-positive MBC, who had previously been treated with trastuzumab plus a taxane or trastuzumab plus pertuzumab combined with a chemotherapeutic agent, were enrolled between March 2020 and December 2021. All patients received pyrotinib 400 mg orally once daily plus vinorelbine 25 mg/m2 intravenously or 60-80 mg/m2 orally on day 1 and day 8 of 21-day cycle. The primary endpoint was progression-free survival (PFS), and the secondary endpoints included the objective response rate (ORR), disease control rate (DCR), overall survival, and safety. Results: A total of 39 patients were enrolled. All patients had been pretreated with trastuzumab and 23.1% (n=9) of them had accepted trastuzumab plus pertuzumab. The median follow-up time was 16.3 months (95% confidence interval [CI], 5.3 to 27.2), and the median PFS was 6.4 months (95% CI, 4.0 to 8.8). The ORR was 43.6% (95% CI, 27.8% to 60.4%) and the DCR was 84.6% (95% CI, 69.5% to 94.1%). The median PFS of patients with versus without prior pertuzumab treatment was 4.6 and 8.3 months (p=0.017). The most common grade 3/4 adverse events were diarrhea (28.2%), neutrophil count decreased (15.4%), white blood cell count decreased (7.7%), vomiting (5.1%), and anemia (2.6%). Conclusion Pyrotinib plus vinorelbine showed promising efficacy and tolerable toxicity as second-line treatment in patients with HER2-positive MBC.

Objective:To comparatively study the similarities and differences between the clinical, pathological, and risk factors of advanced fibrosis in men and women with non-alcoholic fatty liver disease (NAFLD).Methods:267 patients with NAFLD diagnosed by liver biopsy were retrospectively included, and were divided into male and female groups. The difference of clinical and pathological indexes were compared between the two groups. The measurement data were in accordance with normal distribution. The comparison between the two groups was performed by independent sample t-test. The non-parametric test was used for non-normal distribution. The classification data were expressed as a percentage, and the chi-square test was used for comparison between groups. Logistic regression analysis was used to analyze the risk factors.Results:The age of onset of NAFLD was significantly lower in male than female patients ( P < 0.01). There was no statistically significant difference between the male and female groups in terms of body mass index and the prevalence of type 2 diabetes ( P > 0.05). Biochemical index: The levels of alanine aminotransferase, albumin, total bilirubin and uric acid were significantly higher in male than female patients ( P < 0.01). Liver pathology: The proportion of ballooning degeneration was significantly lower in male than female patients ( P < 0.01). There was not statistically significant difference between the two groups in the proportion of steatohepatitis score, non-alcoholic steatohepatitis (52.0% vs. 61.5%, P = 0.283) and advanced liver fibrosis (14.3% vs. 17.8%, P = 0.162). Thrombocytopenia was a common independent risk factor for advanced stage liver fibrosis ( OR = 0.984, 0.978~0.989, P < 0.01). Type 2 diabetes was only an independent risk factor for advanced stage liver fibrosis in men ( OR = 6.557, 1.667~25.782), P < 0.01). Elevated AST was only an independent risk factor for advanced stage liver fibrosis in women ( OR = 1.016, 1.003~1.028, P = 0.012). Conclusion:In NAFLD patients, there are some clinical and pathological differences between genders. Platelets are a common predictor of advanced liver fibrosis in men and women. Type 2 diabetes in men and elevated aspartate aminotransferase in women can be regarded as independent risk factors for advanced liver fibrosis.

Objective To investigate the molecular mechanism through which calenduloside E inhibits hepatocellular carcinoma(HCC)cell proliferation and migration.Methods HCC cell lines HepG2 and Huh7 treated with calenduloside E were examined for changes in cell viability using CCK-8 assay and expressions of GPX4,SLC7A11,LC3,P62 and phosphorylation of Akt/mTOR using Western blotting.The effects LY294002 and Rapamycin(the inhibitor and activator of autophagy,respectively)on proliferation and migration of calenduloside E-treated HCC cells were evaluated using EdU and Transwell assays.The TCGA database was used to explore the expression levels of GPX4 and SLC7A11 in HCC and normal liver tissues and their correlation with the patients'survival outcomes.GPX4 and SLC7A11 expressions were also detected in HCC cells and normal hepatocytes using RT-qPCR and Western blotting.Results Calenduloside E obviously inhibited the viability of HCC cells.GPX4 and SLC7A11 were highly expressed in HCC tissues and cell lines,and their expression levels were negatively correlated with the patients'survival.In HCC cell lines,calenduloside E significantly inhibited the expressions of GPX4 and SLC7A11 proteins,activated the Akt-mTOR pathway,and enhanced the expression of LC3 II.The inhibitory effect of calenduloside E on GPX4 and SLC7A11 expressions was significantly enhanced by rapamycin but attenuated by LY294002.Inhibiting the autophagy pathway obviously diminished the inhibitory effect of calenduloside E on proliferation and migration of HCC cells,while activating this pathway produced the opposite effect.Conclusion Calenduside E inhibits the proliferation and migration of HCC cells by down-regulating GPX4 and SLC7A11 expression via the autophagy pathway.

One of the significant hurdles in telemedicine, particularly in ophthalmology, is the absence of direct physical examination. This specialty depends extensively on specialized instruments that typically require proficient operators. Visual function tests are crucial for both outpatient and inpatient ophthalmic services, playing a vital role in screening, diagnosing, monitoring treatment effectiveness, and managing follow-ups for various eye conditions. The progress in mobile technology has paved the way for expanding these tests beyond traditional clinic settings, promoting the creation of patient-focused, straightforward, cost-effective, and efficient measurement tools. In light of the swift advancement of digital technologies, this article reviews the characteristics, and reliability of self-administered visual function tests tools, including visual acuity, refractive error assessment, visual field, contrast sensitivity, and color vision, along with other pertinent diagnostic tools that have been developed and validated for accuracy and repeatability through research, with a view to providing ophthalmologists and patients with scientific and practical references when selecting and using these tools, further promoting efficiency and efficacy of teleophthalmology.

Medical images can provide clinicans with accurate and comprehensive patients’ information. Morphological or functional abnormalities caused by various diseases can be manifested in many aspects. Although MR images and CT images can highlight the medical image data of different tissue structures of patients, single MR images or CT images cannot fully reflect the complexity of diseases. Using MR image to predict CT image is one of the cross-modal prediction of medical images. In this paper, the methods of MR image prediction for CTmage are classified into four categoriesincluding registration based on atlas, based on image segmentationmethod, based on learning method and based on deep learning method. In our research, we concluded that the method based on deep learning should bemore promoted in the future by compering the existing problems and future development of MR image predicting CT image method.
