Abstract Objective To investigate the effects of 5-hydroxytryptamine 3 receptor antagonists (ondansetron [OND]) versus dopamine receptor antagonists (droperidol [DRO]) in the prevention of postoperative nausea, vomiting (PONV) and headache by pooling data from open published studies. Methods Performed systematic electronic searches of PubMed, Embase, Google scholar and CNKI, to identify open-published prospective randomized controlled trials (RCTs) relevant to the comparison of OND versus DRO for preventing PONV and headache to be included in the present study. The pooled PONV, headache, dizziness and drowsiness were calculated based on the original data of each included study. The pooled data was presented with risk ratio (RR) and 95% confidence interval (95%CI). Results Thirteen prospective randomized clinical trials were included in this meta-analysis. The pooled PONV, post-operative nausea (PON) and positive operative vomiting (POV) were 0.67 (95%CI:0.48-0.93, p<0.05), 0.88 (95%CI:0.67-1.14, p>0.05) and 0.56 (95%CI:0.39-0.82,p<0.05) respectively for OND vs. DRO. And the overall pooled positive operative nausea and vomiting was 0.71(95%CI:0.60-0.86) by fixed effects model for OND vs. DRO. The pooled risk of postoperative headache, dizziness and drowsiness were 4.33 (95%CI:0.76-24.69, p>0.05), 0.63 (95%CI:0.21-1.87, p>0.05) and 0.48(0.28-0.81,p<0.05) respectively by fixed effect model for OND vs. DRO. Conclusion The post-operative nausea, vomiting and dizziness risks were significant decreased for patients receiving OND compared to patients receiving DRO.

Abstract Objective: To investigate the correlation between serum neopterin, homocysteine (Hcy) and the risk of developing ischemic stroke (IS) in patients with transient ischemic attack (TIA). Methods: Ninety-two TIA patients were prospectively recruited at the First Affiliated Hospital of the Medical College, Shihezi University, Xinjiang Autonomous Region China. Of the included patients, 27 developed ischemic stroke (IS group) and other 65 cases did not (TIA group). Peripheral venous blood was obtained within 24 hours of TIA diagnosis. Serum neopterin, Hcy and serum lipid levels were tested and compared between IS and TIA groups. Results: Serum neopterin (6.38±1.76 ng/mL vs 5.39±1.51 ng/mL), Hcy (17.95±4.10 μmol/L vs 15.30±3.66 μmol/L), TG (1.82±0.92 mmol/L vs 1.40±0.71 mmol/L) and LDL (3.31±0.67 mmol/L vs 2.69±0.62 mmol/L) of IS group were significantly higher than those of TIA group (p<0.05). The AUC of serum neopterin, Hcy, TG and LDL for predicting the risk of developing IS in patients with TIA were 0.68 (95%CI: 0.55-0.81, 0.68 (95%CI: 0.57-0.80), 0.64 (95%CI: 0.51-0.78) and 0.75 (95%CI: 0.63-0.86), respectively. Conclusion: Serum neopterin, Hcy, TG and LDL are promising serological markers for predicting the increased risk of developing IS for patients with TIA.

Abstract Objective The aim of this study was to evaluate the dynamic changes of serum neopterin and its significance as biomarker in differentiation of MODS from sepsis. Methods Fifty eight critical illness patients and 21 healthy controls were included in the study. Of the included 58 critical illness patients, 37 cases were diagnosed of sepsis (sepsis group) and other 21 were non-sepsis subjects (non-sepsis group). Of the 37 sepsis patients, 17 were diagnosed of multiple organ dysfunction syndrome (MODS group). The serum level of neopterin of the above subjects were examined by enzyme linked immunosorbent assay and compared between groups. Results The serum level of neopterin were 0.885±0.34(ng/mL), 3.77±2.08(ng/mL), 14.80±6.78(ng/mL) and 23.90±11.26(ng/mL) for healthy control, non-sepsis, non-MODS and MODS groups respectively with significant statistical difference (F=52.71, p<0.001). Serum neopterin level of non-sepsis, non-MODS and MODS groups were statistical different in the time points of 0, 24h, 48h, 72h, and 96h (p<0.05). The serum neopterin level was significant higher in MODS group compared to nonsepsis and non-MODS groups (p<0.05). Using the serum neopterin as biomarker in differentiation of MODS from sepsis, the diagnostic sensitivity, specificity and AUC were 70.59% (95%CI:44.04-89.69) %, 80.00% (95%CI:56.34- 94.27)% and 0.74(95%CI:0.57-0.91)% respectively. Conclusion Serum neopterin levels in patients with sepsis were elevated and can be used as a promising biomarker in differentiation of MODS from sepsis.

Abstract Objective To investigate the predictive value of serum neopterin for multiple organ dysfunction syndrome (MODS) in severe burn patients. Methods Seventy-six severe burn patients with burns covering a total body surface area (TBSA) above 70% were included in this study. Of the 76 patients, 29 cases developed MODS (MODS group) and the remaining 47 subjects did not (non-MODS group). From the MODS group, 12 patients died (Death group) and 17 patients survived (Survive group). The serum level of neopterin in the MODS and non-MODS groups were examined by radioimmunoassay on following 1, 3 , 7 , 14 , 21 and 28 post-burn days (PBDs). A receiver operating characteristic (ROC) curve was used to analyse the predictive value of serum neopterin for MODS and death. Results The serum neopterin level in the MODS group was significantly higher than that of non-MODS group between 3~28 PBDs (p<0.001). However, the serum neopterin levels between the MODS and non-MODS groups following 1 PBD were not statistically significant (p>0.05). The best diagnostic performance of serum neopterin for MODS occurred 14 PBDs with the prediction sensitivity and specificity of 75.86% (56.46%~89.70%) and 85.11% (71.69%~93.80%) respectively. However, serum neopterin levels had no clinical value in predicting the death of MODS patients. The area under the ROC curve (AUC) was 0.72 (0.58~0.85), 0.81 (0.71~0.92) and 0.83 (0.72~0.94) for serum neopterin as biomarker in the prediction of MODS after 3, 7 and 14 PBDs, respectively. The AUCs were 0.50 (0.27~0.73), 0.53 (0.30~0.76) and 0.56 (0.33~0.79) for serum neopterin as biomarker in prediction of death for MODS patients after 3, 7 and 14 PBDs, respectively. Conclusion The persistent and significant increase of serum neopterin level is closely related to the development of MODS in patients with severe burns. Serum neopterin is therefore a promising serological marker for MODS early diagnosis, but has little efficacy in the prediction of the likelihood of death in severe burn patients with MODS.

Abstract Non-specific inflammatory bowel diseases (IBD) include Crohn’s disease (CD) and ulcerative colitis (UC). Both diseases are characterized by chronic inflammation of unclear etiology. The inflammatory bowel diseases incidence is continuously observed to rise. Colon inflammatory response is a physiological process which occurrence is indispensable as an organisms’ defense reaction. The inflammation may be caused by internal factors associated with body’s cells as well as external factors, such as infections and exposition for inflammatory agents. Until recently, IBD have been classified as autoimmune diseases, today they seem to be associated with gut barrier disorders or dysbiosis. Factors that predispose to inflammatory bowel diseases include: genetic factors, dysbiosis and so called western-type diet, natural components such as gluten and lactose. In addition, the development of the disease is favored by: cigarette smoking, phosphate, nanomolecules, sodium chloride, emulgents, carrageenan, carboxymethylcellulose, pollution, maltodextrin. IBD affects whole the body, causing serious medical consequences. Symptoms like anxiety and chronic stress, that occur commonly, can lead to depressive disorders. Quantitative and qualitative dietary deficiency caused by absorption disorders, may promote the occurrence of osteoporosis and osteopenia. In addition, dysbiosis coexisting with alterations in intestinal permeability can lead to the development of nonalcoholic fatty liver disease. IBD medical consequences include also systemic complications, associated with the extra gastrointestinal manifestations’ occurrence.

Abstract Folic acid is a naturally occurring pteridine, which was originally isolated from plants. Folic acid (pteroyl-glutamic acid) is composed of pteridine (6-methylptero), p-aminobenzoic acid (PABA) and glutamic acid. Folic acid (folacin) is a compound of major importance for the proper functioning of the human body. Its adequate supply is essential for the proper course of many biochemical processes in the body, including the process of neural tube closure in the fetus, DNA and amino acid synthesis, growth of red blood cells, and the function of the nervous system. Folic acid is a compound of a high sensitivity to physical and chemical factors, and its bioavailability is limited by interactions with multiple food components. Therefore, folate deficiency is one of the most common deficiencies. This paper presents the structure and characteristics of folic acid as a pteridine, it also discusses dietary sources of folate and the effects of its deficiency.

Abstract Objective: To investigate the serum concentration of folic acid, procalcitonin (PCT), C-reactive protein (CRP) and erythrocyte sedimentation rate (ESR) as biomarkers in the differentiation of the severity of ulcerative colitis (UC). Methods: Fifty one patients who had been diagnosed with UC were recruited from January 2014 to August 2017. Twenty-two of these patients had severe diseases while the remaining twenty-nine patients had mild/moderate disease, according to the Truelove-Witts classification criteria. In the same study, 26 healthy subjects which served as the healthy controls were included alongside the UC patient group. The serum folic acid, PCT, CRP and ESR were examined and compared among the healthy control, mild/moderate and severe UC groups. Results: The serum PCT, CRP and ESR in the control group were significantly lower than those of mild/moderate and severe UC groups with statistical significance (p<0.001). However, the serum folic acid in the control group was significant higher than that of mild/ moderate and severe UC groups (p<0.001). The serum folic acid (p=0.015), PCT (p<0.001) and ESR (p<0.001) were significantly different between the severe and mild/moderate groups. However, the serum CRP was not statistically significant between the mild/moderate and severe UC groups (p=0.06). Using serum folic acid, PCT, CRP and ESR as biomarkers in the differentiation of mild/moderate and severe UC, the serum PCT had good diagnostic accuracy for detecting severe UC with the diagnostic sensitivity and specificity of 85.71% (63.66~96.95%), 82.76% (64.23~94.15%), respectively under the cut off value of 0.045. The correlation between serum CRP, ESR and PCT were examined by Pearson correlation test and line regression analysis. However, there was no correlation between each of them with the exception of folic acid and ESR (r=-0.334, p=0.017). Conclusion: Serum folic acid, PCT, CRP and ESR are significantly elevated in patients with active UC thereby presenting novel and potentially promising biomarkers for the diagnosis and differentiation of mild/moderate and sever UC.

Abstract Background: The aim of this study was to investigate the diagnostic performance of serum homocysteine (Hcy) and Essen stroke risk score (ESRS) in prediction of progressing acute ischemic stroke (PAIS). Methods One hundred and thirty two acute ischemic stroke (AIS) patients were retrospectively recruited from Daping Hospital, Third Military Medical University from February 2016 to January 2018. The 132 AIS patients were divided into PAIS and non-progressing AIS (NPAIS) groups according to the definition of PAIS. The clinical characteristics, serum Hcy concentration, and ESRS were compared between the PAIS and NPAIS groups. The independent risk factors for PAIS were evaluated by logistic regression analysis. The prediction sensitivity, specificity and area under the ROC curve (AUC) of serum Hcy and ESRS for PAIS were calculated using STATA11.0 software. Results: The elevated ESRS (OR=1.82, p<0.05), serum fibrinogen (FIB) (OR=1.18, p<0.05), Hcy (OR=1.21, p<0.05) and personal stroke history (OR=1.74, p<0.05) were independent risk factors for PAIS. The serum Hcy of the PAIS and NPAIS groups were 24.59±9.24 (μmol/L) and 18.20±8.29 (μmol/L) respectively with a statistical significance of p<0.05. The ESRS were 3.43±1.09 and 2.60±0.92 for the PAIS and NPAIS groups respectively, with a significance of p<0.05. The prediction sensitivity, specificity and AUC were 76.24%, 67.74% and 0.73 (95%CI:0.63-0.83), respectively, for serum Hcy. For ESRS, the prediction sensitivity, specificity and AUC were 69.99%, 64.52% and 0.74 (95%CI:0.63-0.84) respectively. Correlation between serum Hcy and ESRS was evaluated by a Pearson correlation test. Significant positive correlation between serum Hcy and ESRS was found in PAIS (r=0.54, p<0.05), and NPAIS patients (r=0.78, p<0.01). Conclusion: Patients with elevated ESRS, serum FIB, Hcy and stroke history had an elevated risk of developing PAIS.

Abstract Endothelial cell (EC) dysfunction has a fundamental role in the development of atherosclerosis, which leads to myocardial infarction and stroke. The aim of this study is to investigate the effect of serum from patients with coronary atherosclerotic heart disease (CAD) on endothelial cells and investigate the possible mechanism underlying these effects. Serum from 35 patients with CAD and 35 healthy volunteers was collected. Human umbilical vein endothelial cell (HUVEC) proliferation and apoptosis were assessed by a CCK‑8 assay and a flow cytometry assay, respectively. The synthesis of nitric oxide (NO) and reactive oxygen species (ROS) was measured using the nitrate reduction method and DCFH2-DA staining, respectively. The proliferation of HUVECs was inhibited by treatment with serum from CAD patients (P<0.05). Suppression of HUVEC proliferation by CAD serum occurred in a concentration-dependent manner. The synthesis of NO was also reduced in the CAD serum-treated group. Furthermore, the serum from CAD patients increased both apoptosis and intracellular ROS production in HUVECs. Moreover, treatment with tempol antagonized CAD serum-meditated HUVEC injuries. Taken together, these results suggest that HUVEC injury via CAD serum treatment is mediated by ROS production. Tempol may partly reverse this effect by abolishing HUVEC apoptosis.

Abstract The aim of this study was to evaluate whether the addition of immunological variables to the Physiological and Operative Severity Score for the enUmeration of Mortality and Morbidity (POSSUM) scoring system improves the predictability of postoperative mortality. One hundred and thirty-two consecutive patients who underwent moderate, major or major-plus elective surgical interventions for gastrointestinal tumors were scored using the POSSUM mortality risk analysis. Patients were placed in one of the two groups based on their POSSUM mortality rates which were either lower or higher than 5%. An additional 26 pre-operative and post-operative metabolic and immunological variables were measured and mortality-dependent variables were selected. Regression analysis with backward elimination of twelve pre-operative and post-operative variables correlating with POSSUM score revealed that post-operative neopterin, IL-6 and albumin were significantly dependent on the predicted mortality rates. According to these selected variables, the number of patients with a POSSUM predicted mortality rate higher than 5% increased from 64 to 88, but the percentage of the mean mortality decreased. Statistical differences between the original POSSUM and modified scoring system was highly significant (p<0.0001). The sensitivity and specificity of the modified scoring system was calculated to be 52.9% and 87.5%, respectively.
