Objective To investigate the effect of fecal microbiota transplantation (FMT) on a rat model of hypertriglyceridemic acute pancreatitis (HLAP). Methods A total of 72 male Sprague-Dawley rats were randomly divided into sham-operation group, model group, Rheum officinale group, and fecal microbiota group, with 18 rats in each group. After 8 weeks of feeding with high-fat diet, the rats in the sham-operation group were given sham operation, and those in the other three groups were given retrograde pancreaticobiliary injection of 5% sodium taurocholate to induce acute pancreatitis; after modeling, the rats in the Rheum officinale group were given enema with Rheum officinale , and those in the fecal microbiota group were given enema with fresh fecal microbiota solution. Blood, pancreatic, and terminal ileal tissue samples were collected at 6, 24, and 36 hours after surgery. HE staining was used to observe histopathological changes of the pancreas and the intestine; an automatic biochemical analyzer was used to measure the serum levels of amylase, alanine aminotransferase (ALT), aspartate aminotransferase (AST), total cholesterol (TC), triglyceride (TG), low-density lipoprotein cholesterol (LDL-C), and high-density lipoprotein cholesterol (HLD-C); ELISA was used to measure the serum levels of interleukin-6 (IL-6), tumor necrosis factor-α (TNF-α), and endotoxin as an index for intestinal permeability. A one-way analysis of variance was used for comparison of normally distributed continuous data between multiple groups, and the least significant difference t -test or the Tamhane T2 test was used for further comparison between two groups; the Kruskal-Wallis H test was used for comparison of non-normally distributed continuous data between multiple groups, and the Bonferroni method was used for further comparison between two groups. Results Compared with the sham-operation group, the Rheum officinale group and the fecal microbiota group had no significant increase in the pathological score of the terminal ileum at 6 and 24 hours, and there was no significant difference between the fecal microbiota group and the sham-operation group at 36 hours (all P > 0.05). At 36 hours, the Rheum officinale group and the fecal microbiota group had a significantly lower serum level of amylase than the model group (all P < 0.05). Compared with the model group, the Rheum officinale group had a significantly lower serum level of ALT at 36 hours ( P < 0.05) and a significantly lower serum level of AST at 24 hours ( P < 0.05), while the fecal microbiota group had a significantly lower level of ALT at each time point ( P < 0.05) and a significantly lower serum level of AST at 24 and 36 hours (all P < 0.05). The Rheum officinale group and the fecal microbiota group had significant reductions in the serum levels of TC and TG (all P < 0.05); compared with the Rheum officinale group, the fecal microbiota group had a significantly higher serum level of HDL-C at 24 and 36 hours (all P < 0.05), and compared with the model group, the fecal microbiota group had a significantly lower serum level of HDL-C at each time period (all P < 0.05). There were no significant differences in the inflammatory indices IL-6 and TNF-α between the fecal microbiota group and the sham-operation group at each time point (all P > 0.05), and the Rheum officinale group had significantly higher levels than the sham-operation group (all P < 0.05); both the Rheum officinale group and the fecal microbiota group had a significantly lower serum level of endotoxin than the model group (all P < 0.05), and the fecal microbiota group had a significantly lower level of endotoxin than the Rheum officinale group within 6 hours of treatment ( P < 0.05). Conclusion Both Rheum officinale and fecal microbiota transplantation can improve tissue inflammation and intestinal permeability in HLAP rats and can improve lipid metabolism and alleviate the progression of pancreatitis to a certain extent, and fecal microbiota transplantation shows a better clinical effect than Rheum officinale alone, but more randomized controlled trials are needed for further investigation.

Objective To understand the nutrition status in elderly patients with hip fracture, and clarify its effects on postoperative functional recovery,complications and mortality based on literature analysis of the past 10 years. Methods PubMed,Medline,Embase Database,Wanfang Database,Chinese National Knowledge Infrastructure(CNKI)and China Biology Medicine disc(CBMdisc)were searched,and relevant researches published from 1st January,2010 to 31th May,2019 were collected. Single rate Meta-analysis was used to integrate the prevalence and mortality of malnutrition. A qualitative systematic review was used to analyze the relationship between nutritional status and prognosis after surgery. Results A total of 11 articles was included,including 21791 patients. Meta-analysis showed that the mean prevalence of malnutrition during hospitalization in elderly patients with hip fracture was 46％(95％CI:45％-47％)using serum albumin(ALB),and was 17％(95％CI:12％-22％)assessing by the Mini Nutritional Assessment (MNA),and the risk of malnutrition prevalence was 42％(95％CI:45％-47％). The results of qualitative evaluation showed that compared with the well-nutrition group(Short-form MNA 12-14 points),the malnutrition risk group(Short-form MNA 8-11 points)had lower activity ability 4 months after the operation (OR=2.03,95％CI:1.24-3.31),and the MNA score decreased by 1 point,the risk of death increased by 15％(HR=0.869,95％CI:0.757-0.998). The malnutrition group(ALB<3.5 g/dl)had a higher incidence of sepsis (P< 0.001)and pulmonary infection(P=0.019),with every 1 g/dl reduction in ALB and 0.59-fold increased risk of death(RR=0.59,95％CI:0.53-0.65). Conclusions The incidence of hip fracture malnutrition or malnutrition risk is very high in the elderly patients with hip fracture. Both malnutrition and malnutrition risk have negative effects on postoperative functional recovery,complications and death rates,and the worse the nutritional status,the worse the prognosis. So,both ALB and MNA are recommended to be included in the care plan of elderly patients with hip fracture. When ALB is failed to diagnose malnutrition,the MNA evaluation method should be adopted to find the problems of nutrition and offer nutritional intervention in advance.

Objective:To construct the nutritional intervention regimen for elderly patients with hip fractures during the perioperative period and rehabilitation period.Methods:Based on Stetler evidence-based practice model, 151 elderly patients with hip fractures surgery who were admitted to Jiading District Central Hospital Affiliated to Shanghai University of Medicine and Health Sciences from January to May 2019 were investigated, and nutritional problems were found in the perioperative period and 3 months after surgery. Through systematic literature search, the best evidence was extracted to construct a nutritional intervention regimen for elderly hip fractures patients with oral nutrition supplements (ONS) . The expert meeting method was adopted to demonstrate the scheme and determine the final intervention scheme and process.Results:A total of 7 guidelines were included, and 25 recommendations were formed based on evidence, including 24 strong recommendations and 1 weak recommendation. Nutritional intervention scheme and process for elderly patients with hip fractures, mainly ONS, were determined. The expert authority coefficient was 0.89.Conclusions:In this study, the nutritional intervention regimen for elderly patients with hip fractures, mainly ONS, was constructed with a high degree of expert authority and reliable results, providing a theoretical basis for clinical nutrition intervention for elderly patients with hip fractures in the perioperative period.

Objective:To explore the influencing factors of fear of falling in patients with first cerebral infarction in recovery period.Methods:Using the convenient sampling method, a total of 221 patients with first cerebral infarction who were hospitalized and treated in Department of Neurology and Department of Cardiology in Qingdao Hospital of Shandong First Medical University from May 2017 to October 2019 were selected as research objects. Short Falls Efficacy Scale International (SFES-I) was used to evaluate the patients, and the influencing factors of the fear of falling in patients with first cerebral infarction in recovery period were analyzed.Results:The results of univariate analysis showed that SFES-I scores of patients with different ages, marital status, family monthly income, history of falls, number of chronic diseases, anxiety, depression, activity of daily living (ADL) limitation and walking ability had statistically significant differences ( P<0.05) . The results of multivariate logistic regression analysis showed that five variables including age (65-80) , marital status, history of falls, anxiety, and depression were retained in the regression model, and the differences were statistically significant ( P<0.05) . Among them, the marital status of the spouse was the protective factors of fear of falling of patients ( OR<1) , while the other 4 factors were risk factors of fear of falling of patients ( OR>1) . Conclusions:Age, marital status, history of falling, anxiety, and depression are the influencing factors of falling fear in patients with first cerebral infarction in recovery period, so targeted nursing measures should be taken according to different characteristics of patients.

Excess activation of cardiac fibroblasts inevitably induces cardiac fibrosis. Emodin has been used as a natural medicine against several chronic diseases. The objective of this study is to determine the effects of emodin on cardiac fibrosis and the underlying molecular mechanisms. Intragastric administration of emodin markedly decreased left ventricular wall thickness in a mouse model of pathological cardiac hypertrophy with excess fibrosis induced by transaortic constriction (TAC) and suppressed activation of cardiac fibroblasts induced by angiotensin II (AngII). Emodin upregulated expression of metastasis associated protein 3 (MTA3) and restored the MTA3 expression in the setting of cardiac fibrosis. Moreover, overexpression of MTA3 promoted cardiac fibrosis; in contrast, silence of MTA3 abrogated the inhibitory effect of emodin on fibroblast activation. Our findings unraveled the potential of emodin to alleviate cardiac fibrosis upregulating MTA3 and highlight the regulatory role of MTA3 in the development of cardiac fibrosis.

Aim To establish a novel acute hyperuricemia mouse model and apply it to evaluate the hyporucicemia effects of Ulodesine, a purine nucleoside phosphorylase(PNP) inhibitor.Methods The mice were intraperitoneal injected inosine and subcutaneous injected Oteracil potassium to induce accumulation of uric acid, and the animal blood was collected from eyeball or vena angularis in different time points.The levels of serum uric acid were measured and determined to test whether the acute hyperuricemia mouse model were successful or not.In order to verify the hyperuricemia seen in the model was associated with the accumulation of inosine, which was converted to uric acid by action of PNP,hyporucicemia effects of Ulodesine, a PNP inhibitor, was assessed in an enzyme assay and confirmed by using the newly established model.Result Accumulation of uric acid in the blood of mouse models was observed by combined injections of intraperitoneal 200 mg·kg-1 inosine and subcutaneous 200 mg·kg-1 Oteracil potassium respectively after 1.5 h.The enzyme assay indicated that Ulodesine was a potently PNP inhibitor with IC50 of 2.293 nmol·L-1.IV injection of Ulodesine eliminated uric acid accumulations in blood of the mouse model, which was expected as the in vivo action of Ulodesine.Conclusions A novel acute hyperuricemia mouse model is established.This is a relatively easy and more effective protocol to generate the hyperuricemia in mice, which will be a useful platform to assess the anti-hyperuricemia activity of PNP-target drugs in vivo.

Objective To observe the role of abatacept in the treatment of diabetic nephropathy in rats. Methods Type 2 diabetic nephropathy rat model was established, and was randomly divided into abatacept group and non-intervention group, 15 each. 15 normal rats were served as control group ( NC) . The abatacept group was given abatacept for 8 weeks. The control group was set at the same time period. Then the blood biochemical indexes, blood flow parameters of renal main artery, elasticity of renal parenchymal, HE staining of renal parenchymal and ultrastructure of podocytes were all evaluated. The expression of CD31, CD34, podocin, nephrin, and B7-1 in renal parenchyma were detected. Results Compared to the NC group, the fasting blood glucose, creatinine clearance rate, urine albumin excretion rate, and kidney hypertrophy index in the non-intervention and abatacept groups were significantly increased (P<0. 05);creatinine clearance rate, urine albumin excretion rate, and kidney hypertrophy index in the abatacept group were significantly lower compared to the non-intervention group (P<0. 05). There were significant differences in peak systolic velocity, end diastolic velocity, and mean velocity among these 3 groups, and these differences were ranked as non-intervention groupabatacept>control groups (P<0. 05). There were significant differences in the stiffness of kidneys among these three groups, with the differences ranked as non-intervention>abatacept>control groups (P<0. 05). HE staining and transmission electron microscope observation showed that there were obvious changes in the renal parenchyma of rats in the non-intervention group and the abatacept group, and the changes of kidney in the non-intervention group were worse than those in the abatacept group. CD31 and CD34 expression in kidney parenchyma of rats in the abatacept group and non-intervention group were higher than those in the control group, the abatacept group and non-intervention group>the control group (P<0. 05), while no significant differences between the abatacept group and non-intervention group in CD31 and CD34 expression (P>0. 05). There were significant differences in podocin and nephrin expression in kidney parenchyma of rats among these three groups, and these differences were ranked as the control>abatacept>non-intervention groups (P<0. 05). There were significant differences in B7-1 expression in kidney parenchyma of rats among these three groups, and these differences were ranked as the control
