Objective:To evaluate the characteristics, clinical management and clinical outcomes of type 2 intestinal failure (IF).Methods:A descriptive case-control study was carried out. The inclusion criteria were as follows: (1) the diagnosis of IF was performed according to the European Society for Parenteral and Enteral Nutrition (ESPEN) consensus statement. (2) using a requirement for parenteral nutrition (PN) of 28 days or more as surrogate marker. (3) a multidisciplinary team (MDT) included surgeons, nutritionist, pharmacist, stoma therapists, and critical care physicians. (4) complete laboratory data. Patients with type 1 and type 3 IF and those who do not cooperate with follow-up. All the data of 67 type II IF were collected from the database in Sir Run Run Shaw Hospital from Jan 2016 to Dec 2023. The pathophysiology, clinical management, and outcomes of type II IF were analyzed.Results:A total of 67 type II IF were included. The median age was 54 (15-83) with 43 males and 24 females. The body mass index was (17.5±3.8) kg/m 2, the incidence of malnutrition was 67.2% (45/67), the incidence of sarcopenia was 74.6% (50/67), the median number of previous surgeries was 2.0 (1-13), and the median duration time of PN was 2.1 (1-12) months. The underlying disease of type 2 IF included 36 Crohn`s disease, 2 ulcerative colitis, 3 radiation enteritis, 2 intestinal Behcet's disease, 4 mesenteric infarction, 1 aggressive fibromatosis, 5 abdominal cocoon syndrome, 5 gastrointestinal perforation, 1 hernia, 4 intestinal dysmotility, and 4 other reasons (gastrointestinal tumor, trauma, and non-Hodgkin's lymphoma). According to the pathophysiology of IF, there were 33 intestinal fistula, 12 intestinal dysmotility, 6 mechanical obstruction, 13 short bowel syndrome, and 3 extensive small bowel mucosal disease. After treatment with MDT, 67 patients with type 2 IF received nutritional support therapy for intestinal rehabilitation treatment, of which 36 patients recovered with oral diet or enteral nutrition, 31 patients underwent reconstructive surgery after intestinal rehabilitation treatment failure. The median duration time of reconstructive surgery was 2.7 (1-9) months. 24 patients recovered intestinal autonomy after surgery, with 7 deaths, including 6 deaths due to abdominal infections and 1 case of intestinal dysmotility with abiotrophy and liver failure. Conclusion:Standardized multidisciplinary treatment plays an important role in type II intestinal failure, and it promotes patients with intestinal failure regain enteral autonomy.

Objective:To investigate the light exposure in neonatal intensive care unit (NICU), and to explore the effect of light management on the growth and development of premature infants.Methods:This study adopted a quasi-experimental research method. Sixty-three premature infants hospitalized in NICU of Obstetrics and Gynecology Hospital Affiliated to Jiangnan University from January to December 2021 were selected by convenience sampling as the control group, and conventional premature infant care measures were implemented, while 60 hospitalized premature infants from January to December 2022 were selected as the observation group, and NICU light management strategies were implemented. The light intensity, bad light exposure, the growth of body mass, body length, hospitalization days of premature infants during hospitalization, and the feeding of premature infants during hospitalization were compared between the two groups.Results:Sixty-three patients were enrolled in the control group, including 28 males and 35 females with a gestational age of (32. 13 ± 1.94) weeks, while 60 patients were enrolled in the observation group, including 32 males and 28 females with a gestational age of (31. 79 ± 1.83) weeks. The daytime and nighttime illuminations in the observation group were (413.79 ± 181.95) and (18.95 ± 12.43) lux, which were better than those in the control group (145.12 ± 99.56) and (53.25 ± 38.34) lux, respectively. The rate of bad light exposure in the observation group was 18.2% (183/1 008). The difference was statistically significant ( t=-29.08, 11.55, χ2=126.99, all P<0.05). In the observation group, the body mass, weekly length gain, hospitalization days, milk intake and age at full feeding on the 7th and 14th day of birth were (1.74 ± 0.32) kg, (1.88 ± 0.32) kg, (1.63 ± 0.60) cm, (26.92 ± 12.32) d, (125.60 ± 69.43) ml/d, (239.33 ± 92.83) ml/d, (15.07 ± 10.01) d, and (1.58 ± 0.31) kg, (1.73 ± 0.31) kg, (1.39 ± 0.48) cm, (32.00 ± 14.00) d, (100.83 ± 68.54) ml/d, (195.05 ± 111.22) ml/d, (18.95 ± 10.76) d in the control group. There were significant differences between the two groups ( t values were -2.89 to 2.13, all P<0.05). Conclusions:The implementation of light management strategy in NICU can effectively reduce the bad light exposure of premature infants, promote their growth and development and shorten the length of hospital stay, which is worthy of clinical application.

Objective To investigate the effect of dapagliflozin on myocardial work and energy metabolism in patients with heart failure with reduced ejection fraction(HFrEF)without type 2 diabetes mellitus(T2DM).Methods Patients with HFrEF without T2DM who visited Wuzhou People's Hospital from January 2021 to January 2022 were randomly divided into conventional group and dapagliflozin group(conventional treatment+dapagliflozin).After treatment(12 months),myocardial work[global work index(GWI),global constructed work(GCW),global wasted work(GW),and global work efficiency(GWE)],energy metabolism[(free fatty acids(FFA)and β-hydroxybutyric acid(β-HB)],traditional cardiac function[left ventricular end-diastolic diameter(LVEDD),left ventricular end-systolic diameter(LVESD),and left ventricular ejection fraction(LVEF)],clinical efficacy,prognosis[mortality,rehospitalization,and incidence of major adverse cardiovascular events(MACE)]and adverse reactions were compared between the two groups.Results A total of 128 patients with HFrEF without T2DM were enrolled,including 63 patients in the dapagliflozin group and 65 patients in the conventional group.After treatment,the LVEDD,LVESD,GWW,NT-pro BNP in the dapagliflozin group was significantly lower than that in the conventional group(P＜0.05),while the LVEF,GWI,GCW,GWE,β-HB acid and FFA were significantly higher than those in the conventional group(P＜0.05).The total effective rate and hypoglycemia rates in the dapagliflozin group were significantly higher than those in the conventional group(P＜0.05),and the rehospitalization rate and MACE rate were significantly lower than those in the conventional group(P＜0.05).There were no significant differences in mortality,renal adverse events,urinary tract infections and gastrointestinal symptoms between the two groups(P＞0.05).Conclusion Dapagliflozin has significant clinical efficacy in patients with HFrEF without T2DM,which can increase the serum levels of FFA and ketones,improve effective work,and reduce ineffective work,but it is necessary to be vigilant against hypoglycemia.

Objective:To analyze the relationship between mesenteric fat or creeping fat and bowel stricture or penetrating disease of Crohn's disease (CD).Methods:Clinical data of 101 CD patients undergoing bowel surgery at Department of General Surgery in our hospital between Mar 2021 and Dec 2021 were retrospectively analyzed. The characteristics of mesenteric fat, creeping fat, luminal cross-section diameter, and the intestinal stricture index were analyzed. The Spearman correlation analysis was used to evaluate the correlation between disease behavior and mesenteric fat score or creeping fat score.Results:Totally 101 CD patients were enrolled, with 68 stricturing diseases and 33 penetrating diseases. CD patients with stricturing diseases had higher score of mesenteric disease activity index (4.6±1.9 vs. 3.7±2.0, t=2.212, P=0.029) and creeping fat index (4.2±2.0 vs. 2.9±1.6, t=3.154, P=0.002) than those in patients with penetrating diseases. The mesenteric fat and creeping fat score positively correlated with the intestinal stricture index, C-reactive protein, and fecal calprotectin, and negatively correlated with minimum luminal cross-section diameter. Conclusion:The higher score of mesenteric fat and creeping fat were observed in CD patients with stricturing disease, which were associated with intestinal stricture index and inflammation status.

Objectives:To assess bowel function and quality of life in patients with ulcerative colitis (UC)after ileal pouch anal anastomosis (IPAA).Methods:Clinical data of 37 UC patients after IPAA between 2014 and 2017 were retrospectively analyzed at Sir Run Run Shaw Hospital School of Medicine Zhejiang University. The IBDQ and Bowel Function questionnaire were used for analyzing correlation between clinical variables and quality of life or bowel function.Results:Laparoscopic operation was performed in 12 cases at stage 2 and 25 cases at stage 3. Postoperative defecation of stage 3 patients were better than that of stage 2 ( t=6.72, P<0.05). The number of daily defecation in age >45-year-old group was more than that in <45-year-old ( t=3.49, P<0.05), and the rate of evening stool seepage in the older group was higher than in the younger group( t=5.28, P<0.05). The total score of intestinal symptoms of IBDQ in patients of pouchitis was lower than that without pouchitis ( r=0.330, P<0.05). The total score in age >45 in terms of systemic symptoms ( r=0.349, P<0.05) and emotional function ( r=0.379, P<0.05) was higher than age <45. Conclusions:Outcomes of UC patients after IPAA are satisfactory, bowel function and quality of life is related with age, and stage of IPAA affect postoperative defecation.

Objectives:To investigate the diagnostic value of whole blood quantitative PCR for DNA load of Epstein-Barr virus (EBV) in post-transplant lymphoproliferative disease (PTLD) after allogeneic hematopoietic stem cell transplantation (allo-HSCT) .Methods:A total of 694 patients with hematologic diseases who underwent allo-HSCT at the Hematology Department of Peking University First Hospital from April 2004 to April 2019 were included, and their data were retrospectively analyzed.Results:①Among the 694 cases, 29 cases (22 males and 7 females, with a median age of 22 (1-52) years) developed PTLD after allo-HSCT with a cumulative incidence of 4.2% and a median onset time of 2.1 (0.8-20.6) months. ② Univariate analysis showed that age<30 years, diagnosis with aplastic anemia, human leukocyte antigen (HLA) mismatch, use of antithymocyte globulin (ATG) in preconditioning regimens, and EBV reactivation were the risk factors for the occurrence of PTLD. Multivariate analysis showed that EBV reactivation was an independent risk factor for the occurrence of PTLD. ③Further analysis of EBV reactivation cases showed that the peak value of EBV-DNA load was significantly higher in the PTLD group than that in the non-PTLD group ( P<0.001) and the incidence of PTLD increased with the increase of EBV-DNA load. Receiver operating characteristic (ROC) curve analysis indicated that PTLD was more likely to be diagnosed when the EBV-DNA load was >1.19×10 6 copies/ml (sensitivity 0.800 and specificity 0.768) . ④All patients with PTLD received rituximab-based treatment, with an overall response rate of 86.2% and an overall survival rate of 54.3%. Conclusion:The PTLD occurrence after allo-HSCT is highly correlated with EBV reactivation, and the higher the EBV-DNA load, the greater the risk of PTLD occurrence. The dynamic monitoring of EBV-DNA load plays an important role in predicting PTLD occurrence.

Objective:To analyze the risk factors for postoperative surgical site infections (SSIs) in patients with Crohn's disease (CD).Methods:This retrospective observational study included CD patients undergoing bowel resection between July 2015 and July 2018. The prevalence and risk factors of SSIs were evaluated. The microbiological evaluation from patients with SSIs was performed by bacterial culture and drug sensitivity test.Results:There were 66 patients suffering SSIs, with 41 incisional SSIs and 32 organ/space SSIs. Multivariate analysis identified the preoperative infliximab therapy ( OR 2.338,95% CI 1.192-4.587, P=0.013), laparoscopic surgery ( OR 0.460,95% CI 0.226-0.936, P=0.013), and preoperative white blood cell ( OR 2.008,95% CI 1.018-3.961, P=0.044) as independent factors for SSIs. Fifty-nine strains of pathogenic bacteria were detected in 66 cases of CD combined with SSIs, including 36 strains of gram-negative bacteria, 5 strains of gram-positive bacteria, and 2 strains of fungi. Escherichia coli and Klebsiella pneumoniae were main G - bacteria, with high resistance to common used antibiotics. Enterococcus faecalis and Enterococcus faecium were main G -. 62.1% of the SSIs grew extended-spectrum β-lactamase (ESBL)-producing pathogens in their bacteria cultures and 37.9% grew non-ESBL microbes. Conclusion:The incidence of SSIs was higher in CD patients. Preoperative infliximab therapy, preoperative white blood cell, and laparoscopic surgery were predictors of SSIs.

Objective: To investigate the effect of continuing nursing mode on mental state and the impact of care capacity in mothers of NICU children with very low birth weight. Methods: Based on the theory of continuous care, a continuation nursing program for children with very low birth weight from the day of discharge from the hospital to one month after discharge was used. A randomized controlled trial was conducted on 80 cases of very low birth weight infants admitted to our hospital. The order of discharge was randomly divided into 40 cases in the intervention group and 40 cases in the control group. The control group received routine care and the intervention group used a continuing nursing intervention model. On the day of discharge from the hospital, 1 week after discharge, and 1 month after discharge, the scores of the mothers' psychological status and home care ability were collected. Results: On the day of discharge, there was no significant difference in mental state and home care ability between the two groups (P>0.05). The anxiety, depression and negative coping scores of the intervention group were lower than the control group at 1 week and 1 month after discharge (1 week t value was 2.138, 2.068, 2.532, 1 mouth t value was 2.273, 3.564, 4.417, P<0.05) , and the scores and home care ability were actively coped. Higher than the control group (1week t value was -1.680, -2.970, P<0.05.1 month t value was -3.937, -7.156, P < 0.01). There was an interaction between intervention mode and intervention time 1 (F value was 8.46-64.38, P<0.01). There were significant differences between the two groups at different time and different groups (different time F value was 166.46-269.55, P<0.01; different groups F value was 5.26-13.55, P<0.05). Conclusion Through continuing nursing intervention for very low birth weight infants after discharge, it can effectively reduce the negative emotions of mothers and improve the positive coping style of mothers, then improve the confidence of caregivers and increase satisfaction so that we can provide a safe and harmonious family environment with premature babies after discharge.

Objectives: Study on the accuracy and influencing factors of neonatal intensive care unit (NICU) critically ill newborns different body parts monitoring by percutaneous oxygen partial pressure (TcpO₂) and carbon dioxide partial pressure (TcpCO₂), in order to provide a basis for non-invasive monitoring of critically ill newborns in ICU. Methods: 60 cases of critically ill newborns requiring blood gas analysis were selected as research cases during July 2017 to March 2018 in Wuxi City Maternity and Child Hospital Neonatology. According to the randomized control principle, three groups were divided, chest group (20 cases), abdomen group (20 cases), leg group (20 cases). The chest group placed the electrodes of the transcutaneous gas analyzer on newborns′ anterior chest. The abdomen group placed the electrodes on newborns′ abdomen. And the leg group placed the electrodes on the inner thigh. PaO₂ and PaCO₂ values were collected from the blood gas results of critically ill newborns. TcpO₂ and TcpCO₂ values were recorded. And at the same time, the electrode shedding situation was observed as well. Compare transcutaneous data and arterial blood data, and do analysis. Result: The chest group TcpO₂ (69.05±9.17) mmHg(1 mmHg=0.133 kPa), TcpCO₂ (46.9±10.57) mmHg, PaO₂ (76.4±8.64) mmHg, PaCO₂ (40.65±4.74) mmHg, the PaO₂ and PaCO₂ values were obviously different from the blood gas analysis results (t=-2.608, 2.413, P<0.05). The abdomen group and the leg group had no significant differences (P>0.05) . And the electrode sheet shedding rate was 30% in the chest group, 25% in the abdomen group, and 10% in the leg group, the three groups had no significant differences (χ²=2.553, P>0.05) . Conclusion NICU critically ill newborns thigh skin monitoring by percutaneous oxygen partial pressure and carbon dioxide partial pressure has high accuracy, and the electrode sheet shedding rate is relatively low. Therefore, it is a safe and effective clinical monitoring method, of great significance for monitoring changes in the condition of critically ill newborns.
