Enteral nutrition plays an irreplaceable role in the nutritional treatment of critically ill patients. In order to help clinical medical staff to manage the common complications during the implementations of enteral nutrition for critically ill patients, the consensus writing team carried out literature retrieval, literature quality evaluation, evidence synthesis. Several topics such as diarrhea, aspiration, high gastric residual volume, abdominal distension, etc. were assessed by evidence-based methodology and Delphi method. After two rounds of expert investigations, Expert consensus on prevention and management of enteral nutrition therapy complications for critically ill patients in China (2021 edition) developed, and provided guidance for clinical medical staff.

Objective To discuss the influence of exogenous Gibberellin (GA3) and abscisic acid (ABA) on genetic expressions of key enzymes in ethylene synthesis in Taizishen (Pseudostillaria Root, Radix Pseudostellariae) , and provide reference for intelligent use of growth regulators during cultivation of Taizishen.Methods The genes of key enzymes in ethylene synthesis of Taizishen were screened and identified from transcriptome database by using local Blast method.Hai'ershen in full-bloom stage was treated with exogenous GA3 and ABA, and samples were collected at different time points (20 d, 40 d, 50 d and 60 d.The genetic expressions of key enzymes in ethylene synthesis of Taizishen were detected by using real-time fluorescence polymerase chain reaction (RT-PCR).Results There were totally 6 genes of key enzymes in ethylene synthesis in roots of Taizishen obtained, and they were named PhACO1, PhACO2, PhACO3, PhACS1, PhACS2 and PhSAMS.GA3 and ABA could regulated the expressions of above 6 genes, and expressions of PhACO1, PhACO2, PhACS1 and PhSAMS were up-regulated after treated with GA3, and expressions of PhACO3 and PhACS2 were up-regulated after 20 d to 40 d and down-regulated after 50 d to 60 d.The expressions of genes of key enzymes in ethylene synthesis in Taizishen showed down-regulation at first and then up-regulation after treated with ABA, but different genes had different demonstrations.The expression of PhACO1 was up-regulated after 20 d to 60 d, and down-regulated after 40 d to 50 d.The expressions of PhACO2 and PhACO3 were down-regulated after 20 d to 50 d, and up-regulated after 60 d.The expression of PhACS1 was down-regulated after 20, up-regulated after 40 d to 60 d.The expressions of PhACS2 and PhSAMS were down-regulated.Conclusion GA3 and ABA may control the ethylene signaling pathway to regulate plant growth through affecting the ethylene biosynthesis of Taizishen.It is speculated that Taizishen is treated with suitable concentration of GA3 in adventitious root growth period and treated with ABA treatment in root thickening period, the yield of Taizishen will be increased.

To investigate the safety and clinical efficacy of endoscopic submucosal dissection (ESD) in the treatment of gastrointestinal neuroendocrine neoplasms (GI-NENs). Methods: The clinical and pathological features of 39 patients with GI-NENs who were treated with ESD, the efficacy of ESD treatment, complications, and follow-up results were analyzed retrospectively. Results: The 39 cases of GI-NENs were all neuroendocrine tumors (NETs). According to histopathology and proliferative activity, there were 37 cases of G1, two cases of G2, and no cases of G3, including 23 cases of cancer in the rectum, 12 in the stomach, 4 in the duodenum. Thirty-five lesions invaded the mucosa or submucosa, four invaded the muscularis propria, one perforated in the ESD, and two were associated with bleeding. After 6 to 90 months of follow-up, new lesions were found in 1 patient with g-NETs in different parts of the stomach at 5 and 34 months after operation, followed by ESD treatment and further follow-up. No lymph node and distant metastases were found, and the survival rate of the patients was 100%. Conclusions: For GI-NENs without lymph node and distant metastases, the lesion is con-fined to the submucosa, and a diameter≤1.0 cm is an absolute indication of ESD. For rectal neuroendocrine neoplasms that have non-invasive muscularis propria with diameters between 1 and 1.5 cm, or for patients with Type 1 gastric neuroendocrine tumors (T1-GNETs) that are predicted to be T2, ESD treatment should be prioritized to preserve gastrointestinal volume and function.

Objective To develop nurses'knowledge,attitude and practice questionnaire on medication management for patients with dysphagia,and test its reliability and validity.Methods Based on the evidence-based summary of the best evidence of medication management for patients with dysphagia,guided by the the-ory of knowledge,attitude and practice,the basic dimensions and item pool of the questionnaire were deter-mined through group discussion,Delphi expert consultation and pre-investigation.In order to revise the ques-tionnaire,437 nurses from 10 tertiary hospitals in Jiangsu Province were conveniently selected for investigation,and the reliability and validity of the questionnaire were tested according to the survey results.Results The nurses'knowl-edge,attitude and practice questionnaire on medication management for patients with dysphagia included 43 items in three dimensions.The three dimensions were analyzed by exploratory factors,and six common factors with characteristic roots>1 were extracted.Two factors were extracted from the knowledge dimension,and the cumulative variance contribution rate was 74.958%,One factor was extracted from the attitude dimen-sion,and the cumulative variance contribution rate was 77.655%.Three factors were extracted from the prac-tice dimension,and the cumulative variance contribution rate was 72.274%.The factor load of each item was 0.618-0.902,Cronbach's α coefficient of the total questionnaire was 0.949,and the test-retest reliability was 0.909.The overall content validity coefficient of the questionnaire was 0.922,and the content validity coeffi-cient for each item was 0.800-1.000.Conclusion The nurses'knowledge,attitude and practice questionnaire on medication management for patients with dysphagia developed in this study has good reliability and validi-ty,and could be used as an effective tool to evaluate the status quo of nurses'medication management for pa-tients with dysphagia.

Objective:To evaluate the risk of bias and applicability of the risk prediction models for pancreatic fistula after pancreaticoduodenectomy (PD).Methods:The relevant studies were systematically searched from Chinese database (Chinese medical journals database, CNKI, Wanfang, Weipu, Sinomed) and English databases (PubMed, Embase, Web of Science, Cochrane Library, CINAHL Database) and the retrieval time limit was from the establishment of the database to December 31, 2023. Based on the risk of bias assessment tool of the predictive model study, the risk of bias and applicability of the model were evaluated, and the predictors with high repetition rate in the model were meta-analyzed by RevMan 5.4 software.Results:A total of 23 studies involving 30 models were included. The incidence of pancreatic fistula was 11.4%-41.7%. nineteen studies reported the discrimination index of model construction and/or validation, and the area under the curve (AUC) was 0.62-0.94. The other four studies reported the consistency index (c-index). The predictive performance of the 23 studies is good, but there is a high risk of bias. The main reasons are that the sample size is not saturated, the research object from the appropriate source is not selected, the continuous variables are not properly processed, and the predictive factors are screened by single factor analysis. Eight studies were rated as " high risk" for applicability due to inconsistencies between the included study subjects and outcome measures and the systematic review study questions. The meta-analysis results showed that the dilation of main pancreatic duct (>3 mm) ( OR=0.70, 95% CI: 0.65-0.76), soft pancreas texture ( OR=5.18, 95% CI: 3.90-6.88), and body mass index ≥25 kg/m 2 ( OR=1.12, 95% CI: 1.07-1.17) were effective predictors of postoperative pancreatic fistula (POPF). Conclusion:The existing predictive models for pancreatic fistula risk in patients undergoing PD both domestically and internationally have good predictive performance, but there is a certain risk of bias and some models have poor applicability. Predictors such as dilation of main pancreatic duct, soft pancreas texture, and body mass index≥25 kg/m 2 should be more emphasized in future predictive models.

Objective:To investigate the influencing factors of participation in free health check-up among community residents.Methods:From 2012 to 2022 Xinzhuang Community Health Service Center of Shanghai Minhang district provided 5 free health check-up for local residents, once every 2 years. Among 5 904 eligible community residents with a mean age of (66.01±5.87) years, 682 (11.55 %), 912 (15.45 %), 842 (14.26 %), 934 (15.82 %), 1 061 (17.97 %) and 1 473 (24.95 %) participated in 5, 4, 3, 2, 1 and 0 health check-ups during 10 years, respectively. The influencing factors of participant frequency were analyzed with multivariate logistic regression model.Results:Multivariate logistic regression analysis showed that age 65 years and above ( OR=0.685, 95% CI: 0.625-0.751, P<0.001), exercising once a week or more ( OR=1.142, 95% CI: 1.031-1.266, P=0.011), and underweight ( OR=0.665, 95% CI:0.496-0.891, P=0.006) were independent factors influencing the participant in free health check-up among community residents. Conclusion:Community residents with older age or underweight are less likely to participate free health check-up, while those with frequent exercise like to participate.

Objective:To detect and analyze the α-galactosidase A ( GLA) gene mutations in Fabry disease patients and their family members, observe the clinical phenotype of the patients, and assess the therapeutic effect of agalsidase alpha. Methods:It was a case series analysis. A total of 5 Fabry disease patients was diagnosed at the First Affiliated Hospital of Sun Yat-sen University from March 2022 to April 2023, and the clinical data and blood samples of the patients and their family members were collected. Genetic testing was performed using whole exome sequencing. GLA activity and substrate concentration were measured using the liquid chromatography-tandem mass spectrometry. Patients' clinical manifestations, family history, and auxiliary examination results were collected, and the therapeutic efficacy of agalsidase alpha and disease progression were followed up.Results:A total of 5 GLA gene mutations were identified by gene sequencing, including 1 novel mutation. Among them, 4 mutations were missense mutation, and the other one was nonsense mutation. Common clinical manifestations included edema (4/5) and reduced sweating (4/5). Renal pathology biopsy of 4 patients showed varying degrees of kidney damage, one of which was combined with IgA nephropathy. Auxiliary examinations revealed ocular involvement in 4 patients, cardiac involvement in 4 patients, and hearing impairment in 2 patients. All 5 patients received agalsidase alpha treatment, with 4 male patients receiving (16.8±5.9) times administrations of agalsidase alpha, and their globotriaosylsphingosine (Lyso-GL-3) levels decreased by 45.6%±15.5% from baseline. Conclusions:One novel GLA gene mutation is detected, which enriches the human gene mutation database. Fabry disease can be accompanied by kidney disease such as IgA nephropathy. When patients present with unexplained proteinuria combined with extrarenal manifestations such as reduced sweating, Fabry disease should be considered. Agalsidase alpha treatment can reduce Lyso-GL-3 concentration, and improve clinical symptoms.

Objective: To compare incidence and clinical features of hemorrhage cystitis (HC) after haploidentical donor (HID) allogeneic hematopoietic stem cell transplantation (HSCT) and matched sibling donor (MSD) HSCT. Methods: Medical records of 609 (including 406 HID-HSCT and 203 MSD-HSCT cases) hematologic malignancies patients treated with HSCT undergoing myeloablative conditioning regimen from January 2011 to December 2012 were analyzed retrospectively. Results: HC occurred 183 in HID and 17 ones in MSD respectively. The cumulative incidence of HC in HID group was higher than in MSD group[ (45.6±2.5) % vs (8.5±2.0) %, χ²=77.331, P<0.001], and the cumulative incidence of severe HC (grade 3-4) in HID cases was also higher than in MSD ones[ (11.2±1.9) % vs (2.1±1.1) %, χ²=12.883, P<0.001]. All HCs were occurred within 180 days in both groups. The median time to onset in two groups were 27 days after HSCT (range 0-177 days) and 29 days after HSCT (range 6-72 days) respectively (P=0.766) . The median duration of HC in two groups were 21 days (range 3-157 days) and 13 days (range 5-67 days) , respectively (P=0.182) . The total efficiency of treatment in two groups were 69.9% and 70.6% respectively (χ²=0.003, P=1.000) . Conclusion The cumulative incidences of HC and severe HC were higher in HID cases than in MSD ones. The median time to onset and median duration of HC and therapeutic outcome between HID and MSD were comparable.

Objective:To explore the risk factors of all-cause death in hypertensive patients in the community.Methods:A cohort of 4 049 hypertensive patients who participated in annual health checkups at Xinzhuang Community Health Service Centre of Shanghai Minhang district from January to December 2012 were enrolled in the study. All-cause death was the endpoint event of this study, and patients were divided into a fatal group and a survival group. The collection date for the endpoint event was December 2022. A multivariate Cox regression model was used to analyse the independent risk factors of all-cause mortality among hypertensive patients in the community.Results:Among 4 049 patients aged (67.9±7.1) years, 1 856 (45.8%) were males. There were 610 cases in the fatal group and 3 439 cases in the survival group. Multivariate Cox proportional regression showed that male gender ( HR=1.446, 95% CI: 1.200-1.742, P<0.001), older age ( HR=1.130, 95% CI: 1.118-1.143, P<0.001), higher waist-to-height ratio ( HR=8.117, 95% CI: 2.235-29.481, P=0.001), positive urinary protein ( HR=2.974, 95% CI: 2.202-4.016, P<0.001), high fasting blood glucose ( HR=1.070, 95% CI: 1.012-1.131, P=0.017), and history of stroke ( HR=1.819, 95% CI: 1.414-2.340, P<0.001) were independent risk factors for all-cause mortality in hypertensive patients, while exercise≥1/week ( HR=0.816, 95% CI: 0.668-0.996, P=0.046) and taking lipid-lowering medications ( HR=0.459, 95% CI: 0.223-0.947, P=0.035) were protective factors for all-cause mortality. Conclusion:For hypertensive patients, male gender, older age, higher waist-to-height ratio, positive urinary protein, high fasting blood glucose, and history of stroke are risk factors for all-cause mortality, while exercise≥1/week and taking lipid-lowering medications are protective factors.

Objective:To analyze the association between sleep status and ambulatory blood pressure monitoring indicators in community-dwelling hypertensive patients.Methods:It was a cross sentional study. Hypertensive patients who underwent 24-hour ambulatory blood pressure monitoring from May 2021 to April 2023 in Shanghai Xinzhuang Town were enrolled. The demographic information and sleep status of patients were obtained from the questionnaire. A TM-2430 blood pressure monitor was used to measure 24-hour ambulatory blood pressure, and the relevant indicators, including blood pressure level and blood pressure coefficient of variation were documented. The association between sleep status and blood pressure indicators was analyzed with multivariate linear regression model.Results:A total 1 135 patients aged (65.07±12.61) years were enrolled, and 473 (41.67%) of whom were males. The sleep time was<7 hours in 76 cases, 7- 8 hours in 219 cases and >8 hours in 840 cases; the bedtime was earlier than 22∶00 in 415 cases, between 22∶00 and 23∶00 in 474 cases and later than 23∶00 in 246 cases; the wake-up time was before 6∶00 in 230 cases, between 6∶00 and 7∶00 in 521 cases and after 7∶00 in 384 cases. Multivariate linear regression analysis showed that after controlling for gender and age, the sleep time was negatively associated with diurnal, noctumal and 24-hour diastolic blood pressure levels (all P<0.05), and positively associated with diurnal and noctumal systolic blood pressure coefficient of variation, noctumal diastolic blood pressure coefficient of variation, and 24-hour systolic blood pressure coefficient of variation (all P<0.05).The bedtime was positively associated with diurnal, noctumal and 24-hour diastolic blood pressure (all P<0.05), diastolic blood pressure (all P<0.05); and negatively associated with diurnal systolic blood pressure coefficient of variation, diurnal diastolic blood pressure coefficient of variation, noctumal systolic blood pressure coefficient of variation, 24-hour systolic blood pressure coefficient of variation, and 24-hour diastolic blood pressure coefficient of variation (all P<0.05). The wake-up time was positively associated with diurnal systolic blood pressure, diurnal, noctumal and 24-hour diastolic blood pressure (all P<0.05), and positively associated with diurmal systolic blood pressure and diastolic blood pressure (both P<0.05). Conclusion:Sleep status is closely associated with ambulatory blood pressure monitoring indicators in community-dwelling hypertensive patients.
