Studies showed that low fermentable oligosaccharides, disaccharides, monosaccharides and polyols (FODMAPs) diet can improve the symptoms of gastrointestinal dysfunction of inflammatory bowel disease (IBD) patients, the mechanism may be related to decrease of secretion of intestinal liquid and production of gas.Specific carbohydrate diet and paleolithic diet may be suitable for IBD patients.This article reviewed the advances in study on effects of different diets on gastrointestinal dysfunction in patients with IBD.

OBJECTIVE: To investigate the effects of the combination of alpha-keto acid and low-protein diet on the levels of serum cytokines in patients performing continuous ambulatory peritoneal dialysis (CAPD) and to explore the relationship between inflammation and malnutrition in CAPD patients. METHODS: Eighty-nine CAPD patients were randomized into three groups, and 78 cases completed a one-year follow-up and with complete data. There were 31 cases in low-protein diet plus alpha-keto acid group, 26 cases in low-protein diet group and 21 cases in routine-protein diet group. The levels of serum albumin (Alb), prealbumin (PA), retinol-binding protein (RBP), transferrin (TRF), cholesterol (TC), triglycerides (TG), leptin, and triceps skinfold thickness (TSF), mid-arm muscle circumference (MAMC), body mass index (BMI) were measured. The changes of serum interleukin-1alpha (IL-1alpha), interleukin-6 (IL-6), tumor necrosis factor-alpha (TNF-alpha) and C-reactive protein (CRP) were also detected. RESULTS: Compared with low-protein diet group, serum levels of PA, RBP and TRF were significantly increased both in low-protein diet plus alpha-keto acid and routine-protein diet groups ( P<0.01), however, there was no significant difference in the levels of PA, RBP and TRF between low-protein diet plus alpha-keto acid group and routine-protein diet group. There was an increased tendency in the content of Alb, TC, TG, BMI, TSF and MAMC, but there were no significant differences. The plasma levels of IL-1alpha, IL-6 and TNF-alpha in low-protein diet plus alpha-keto acid group were decreased as compared with the routine-protein diet group, but there were no significant differences. The plasma level of CRP in low-protein diet plus alpha-keto acid group was lower than that in the routine-protein diet group ( P<0.01). CONCLUSION: The combination of alpha-keto acid and low-protein diet can ameliorate malnutrition and micro-inflammation in CAPD patients.

Objective To investigate the relationship between baseline serum uric acid and the severity of coronary artery disease ( CAD ) in the first-degree relatives or non-first-degree relatives of men with type 2 diabetes. Methods Three hundred and eighty-one men with negative coronary angiography for the first time were divided into diabetes and non-diabetes groups and followed-up for 5 years. The primary outcome was acute coronary syndrome suspected during subsequent 5 years, and the coronary angiography was conducted simultaneously. The severity of CAD was assessed by the coronary stenosis index ( CSI) and the number of coronary lesion vessels. Results In normal blood glucose group, serum uric acid was higher in the first-degree relatives of diabetics compared with non-first-degree relatives(P<0. 01), along with higher morbidity of CAD, CSI, and coronary lesion vessels (all P<0.01). Correlation analysis showed that CSI(r=0. 250, P=0. 041) and coronary lesion vessels(r=0. 252, P=0. 040) in non-diabetics group were associated with baseline levels of serum uric acid. Conclusion The elevation of serum uric acid was closely related to subsequent CAD, especially in first-degree relatives of male with type 2 diabetes, which could be used as an early indicator for CAD prediction.

Objective:To observe the effects of FNS007 on collagen Ⅱ-induced arthritis(CIA) rat models and investigate the underlying mechanism.Methods: CIA model was induced by intradermal injection of Freunds adjuvant and bovine CⅡ.Rats were randomly divided into six groups:normal control group,model group,methotrexate group,high,middle and low doses of FNS007 groups,with 12 rats in each group.FNS007 was gived by intravenous injection,the normal control and model group were administrated with PBS.Observing the paw thickness,ankle joint width and the arthritis scores in the CIA rats during the experiment.On d 22 after injection of the drug, all rats were killed.Interferon-γ(IFN-γ),tumor necrosis factor-α(TNF-α),interleukin-6 (IL-6) and level of anti-CⅡantibody in serum were examined by enzyme-linked immunosorbent assay (ELISA).The pathological score and radiography of ankle joint were evaluated.Results: Data revealed that FNS007 treated groups showed a significant reduction in paw thickness,ankle joint width and the arthritis scores compared to model group (P<0.05,P<0.01),especially FNS007 high dose goup.The levels of TNF-α,IFN-γ,IL-6 and anti-CⅡantibodies in serum in high dose goup were significantly lower than those of model group(P<0.05,P<0.01).X-ray examination showed that FNS007 could significantly alleviate the damage of joint and decrease the radiographic scores.Pathological examination exhibited that FNS007 could significantly reduce pathological scores,alleviate inflammatory cell infiltration and synovial hyperplasia,improve the histopathological changes.Conclusion: FNS007 has a treating effect on CIA rats,and the mechanisms may be through competitive inhibition of T cell,inhibiting inflammatory cytokines and anti-CⅡantibodies secretion,regulating the abnormal immune responses.

Aim To investigate the effect of non-T cell binding peptide(FNS007)on collagen type Ⅱ-induced arthritis(CIA)in mice and the possible mechanisms.Methods The CIA model was induced by intradermal injection of bovine CⅡ+Freunds adjuvant.At the clinical onset of CIA,mice were randomly divided into 6 groups: blank control group(Control),model group,ORENCIA(abatacept)group,FNS007 low dose(1.2 mg·kg-1)group,FNS007 middle dose(2.4 mg·kg-1)group and FNS007 high dose(4.8 mg·kg-1)group.FNS007 was given by intravenous injection on the first day of arthritis and every other day until the study was terminated on d 28 after injection of the drug.The paw thickness and the ankle joint width were measured,and the arthritis scores were recorded.At termination,interferon-γ(IFN-γ),tumor necrosis factor-α(TNF-α),interleukin-6(IL-6)and level of anti-CⅡ antibody in serum were examined by enzyme-linked immunosorbent assay(ELISA).Bone injury was analyzed by X-ray imaging,and HE staining was conducted to observe the histopathologic changes and pathological score of ankle tissues.Results CIA models were successfully induced.Compared with CIA group,FNS007 high dose significantly reduced the paw thickness and the ankle joint left-right diameter,lowered arthritis scores in CIA mice,reduced serum concentrations of IFN-γ,IL-6 and anti-CⅡ antibodies,and lowered the radiographic and histologic scores.Compared with CIA group,FNS007 middle dose group showed marked reduction in the arthritis scores,IL-6 content in serum,and inhibion in the radiographic and histologic scores.The arthritis scores,concentration of IFN-γ,the radiographic and histologic scores were significantly reduced in FNS007 low dose group compared with those in model group.Conclusion FNS007 can effectively inhibit the progression of CIA through inhibiting T-cell activation and reducing inflammatory cytokines,anti-CⅡ antibodies,and histoclasia and bone destruction.

Objective To investigate the neuroprotective effect and mechanism of liraglutide on diabetic rats. Methods 24 healthy male SPF Goto-Kakizaki (GK) rats with random blood glucose greater than 11.1 mmol/L were selected as the experimental group, and randomly divided into diabetes mellitus group ( n＝12) and liraglutide group (n＝12). Ten healthy male SPF Wistar rats with the same age and weight as GK rats were selected as normal control group. After adaptively feeded for 2 weeks, the liraglutide group was given liraglutide (400 μg·kg－1·d－1, subcutaneous injection), while the control group and diabetes mellitus group were given the same volume of saline, and continued to be administered for 8 weeks. After 10 weeks, data and biochemical indicators were recorded. Effects of liraglutide on learning and memory in diabetes mellitus rats were detected by Morris water maze test. HE staining observed the hippocampal neurons morphology. Western blotting method detected the expression of p- IκB kinase (IKK) β, p-NF-κB, NF-κB, Klotho, and PRX2 in hippocampus. Results Morris water maze test showed that liraglutide can improve the spatial learning and memory ability of diabetes mellitus rats. HE staining showed that liraglutide significantly reduced the pathological damage of hippocampal neurons of diabetes mellitus rats. Western blotting showed that liraglutide inhibited NF-κB signaling pathway in hippocampus of diabetes mellitus rats. The expression of Klotho protein in hippocampus of diabetes mellitus group was significantly lower than that of control group, while the expression of PRX2 protein was higher than control group (t＝8.298,－7.398,all P<0.01). The expression of Klotho and PRX2 protein in hippocampus of liraglutide group were higher than diabetes mellitus group (t＝－13.059, 14.113, all P<0.01). The expression of Klotho protein of liraglutide group was similar to that of control group ( t ＝ －1. 137, P>0. 05 ). The expression of PRX2 protein was significantly higher than control group (t＝－28.055, P<0.01). Conclusions Liraglutide may enhance the expression of antioxidant stress protein including Klotho and PRX2, by inhibiting NF-κB signaling pathway in hippocampus of diabetes mellitus rats, reduced oxidative stress and improved the injury of hippocampal neuronal in diabetes mellitus rats, which seems to play a neuroprotective effect, to prevent and delay the occurrence of diabetic encephalopathy.

Objective:To evaluate the relationship between blood transfusion factors (massive transfusion, transfusion of stored red blood cells and anhepatic transfusion) and early postoperative outcomes in the patients undergoing orthotopic liver transplantation.Methods:Patients with end-stage liver disease who underwent orthotopic liver transplantation and intraoperative blood transfusion from January 2021 to March 2022 in our hospital were retrospectively selected, and their clinical data were collected. The patients were divided into massive transfusion group (M group, total red blood cell transfusion ≥10 U) and non-massive transfusion group (NM group) according to the amount of intraoperative blood transfused. The patients were divided into fresh blood group (NS group) and stored blood group (S group, red blood cell storage time > 2 weeks) according to the storage time of red blood cells transfused. The patients were divided into transfusion in anhepatic stage group (group T) and nontransfusion in anhepatic stage group (group NT) according to whether blood was transfused in the anhepatic stage. Multivariate logistic regression, generalized linear model and generalized linear mixed model were used to analyze the relationship between blood transfusion factors and primary outcome measures (postoperative pulmonary complications, circulation overload, acute kidney injury, abdominal infection, thrombosis) and between blood transfusion factors and secondary outcome measures (duration of ICU stay, postoperative hospitalization, postoperative temperature ≥38.5 ℃ at any time point after surgery, postoperative liver and kidney function index, coagulation function index, platelet count and preoperative difference).Results:One hundred and six patients were enrolled in this study. The results of multivariate logistic regression analysis: Massive blood transfusion and infusion of stored blood were risk factors for postoperative pulmonary complications, massive blood transfusion was a risk factor for abdominal infection, Child-Turcotte-Pugh score for liver function and time of anhepatic phase were risk factors for postoperative acute kidney injury, Child-Turcotte-Pugh score was a risk factor for circulatory overload, and age and massive blood transfusion were risk factors for thrombosis ( P<0.05). The results of generalized linear model analysis: Intraoperative stored blood transfusion and blood transfusion during the anhepatic phase were risk factors for prolonged duration of ICU stay, massive blood transfusion, intraoperative stored blood transfusion and blood transfusion during the anhepatic phase were risk factors for prolonged hospitalization ( P<0.05), and there was no correlation between massive blood transfusion, intraoperative stored blood transfusion and blood transfusion during the anhepatic phase and temperature ≥38.5 ℃ at any time point after surgery ( P>0.05). The results of generalized linear mixed model analysis: There was statistically significant difference in the difference between preoperative and postoperative liver and kidney function indexes, coagulation function indexes and platelet counts in the patients with or without massive transfusion, stored blood transfusion or blood transfusion during the anhepatic phase ( P<0.05). Conclusions:Massive blood transfusion and infusion of stored blood are the main risk factors for early adverse outcomes after orthotopic liver transplantation in the patients.

Products made from allogeneic tissue are largely used in clinical treatment due to its wide source compared with autologous tissue, causing less secondary trauma of patients and the good biocompatibility. Various organic solvents and other substances introduced in the production process of allogeneic products will leach down into the human through clinical treatment, thus bringing varying degrees of harm to patients. Therefore, it is very necessary to detect and control the leachables in such products. Based on the classification and summary of leachable substances existing in the allogeneic products, the preparation of extract and the establishment of the detection techniques for known and unknown leachable are briefly introduced in this study, in order to provide research method for the study of leachable substances of allogeneic products.

Objective:To study the prevalence and distribution of adult thyroid diseases in urban and rural areas of Hebei Province.Methods:A multi-stage stratified cluster sampling method was used to select Renqiu City and Licun Town, Luquan City of Hebei Province as the urban and rural survey sites, respectively. Questionnaire survey, physical examination and thyroid B ultrasound examination were conducted on local permanent residents (≥ 5 years of residencies) over 18 years old. The fasting venous blood sample was collected to determine the serum thyroid function indicaters.Results:A total of 2 650 adults were surveyed, including 1 393 urban residents and 1 257 rural residents (1 357 males and 1 293 females). A total of 435 patients with thyroid diseases were diagnosed, the detection rate was 16.42%. There were seven thyroid diseases, including subclinical hypothyroidism (60.92%, 265/435), Hashimoto's thyroiditis (34.02%, 148/435), hypothyroidism (4.83%, 21/435), simple goiter (3.22%, 14/435), hyperthyroidism (2.53%, 11/435), subclinical hyperthyroidism (2.53%, 11/435), and thyroid cancer (1.84%, 8/435). The detection rates of thyroid diseases in urban and rural areas were 21.18% (295/1 393) and 11.14% (140/1 257), respectively. The detection rates of thyroid diseases in males and females were 11.42% (155/1 357) and 21.66% (280/1 293), respectively. The detection rates of thyroid diseases in 18-< 30, 30-< 40, 40-< 50, 50-< 60 and ≥60 years old were 13.46% (91/676), 14.81% (81/547), 15.42% (89/577), 20.94% (85/406) and 20.05% (89/444), respectively. There were statistically significant differences between different areas, gender and age groups (χ 2 = 48.54, 50.53, 14.68, P < 0.05). Conclusions:The detection rate of subclinical hypothyroidism in adults in urban and rural areas of Hebei Province is relatively high, followed by Hashimoto's thyroiditis. Attention should be paid to the screening, evaluation, and intervention of thyroid function among urban female populations.
