ABSTRACT
Objective: Dental caries is one of the most common microbial diseases. Because of the infectious nature of the disease, the immunologic response by the host plays an essential role in its development. Therefore, the aim of this study was to evaluate the sCD14 levels in patients exhibiting two to three teeth with caries involving pulp along with apical periodontitis requiring root canal treatment. Material and Methods: This study was carried out on 20 participants, of whom 10 were caries-free (Control) and 10 had two to three teeth with symptomatic irreversible pulpitis along with apical periodontitis requiring root canal treatment, within the ages of 20- 30 years. Unstimulated saliva of the participants was collected with disposable needle-less syringe from buccal and labial vestibules. The sCD14 levels in salivary samples were assessed before and following endodontic treatment. The results were analyzed by ELISA. Results: The obtained levels of sCD14 were analyzed statistically. Paired T test was performed to assess the significance. The results revealed that there was a significant difference in sCD14 levels with a P=0.0005, as it had drastically reduced once the inflammation has subsided. Conclusion: Higher values of sCD14 levels were seen in patients with symptomatic irreversible pulpitis along with apical periodontitis than in caries free group. The study also showed that sCD levels were significantly reduced following post endodontic treatment. Therefore, increased levels of sCD14 can be considered as a marker of inflammation. (AU)
Objetivo: A cárie dentária é uma das doenças microbianas mais comuns. Devido à natureza infecciosa da doença, a resposta imunológica do hospedeiro desempenha um papel essencial no seu desenvolvimento. Portanto, o objetivo deste estudo foi avaliar os níveis de sCD14 em pacientes que possuiam dois a três dentes com necessidade de tratamento endodôntico por apresentarem lesão de cárie envolvendo polpa e periodontite periapical. Material e Métodos: Este estudo foi realizado em 20 participantes, dos quais 10 estavam livres de cárie (controle) e 10 tinham dois a três dentes com pulpite irreversível sintomática e periodontite periapical com necessidade de tratamento endodôntico, nas idades de 20 a 30 anos. A saliva não estimulada das crianças foi coletada com seringa descartável sem agulha dos vestíbulos bucal e labial. Os níveis de sCD14 em amostras salivares foram avaliados antes e após o tratamento endodôntico. Os resultados foram analisados por ELISA. Resultados: Os níveis de sCD14 obtidos foram analisados estatisticamente. O teste T pareado foi realizado para avaliar a significância. Os resultados revelaram que houve uma diferença significativa nos níveis de sCD14 com um P = 0,0005, uma vez que reduziu drasticamente uma vez que a inflamação diminuiu. Resultados: Os níveis de sCD14 obtidos foram analisados estatisticamente. O teste T pareado foi realizado para avaliar a significância. Os resultados revelaram que houve uma diferença significativa nos níveis de sCD14 com um P = 0,0005, uma vez que reduziu drasticamente uma vez que a inflamação diminuiu. Conclusão: Valores mais elevados de níveis de sCD14 foram observados em pacientes com pulpite irreversível sintomática junto com periodontite periapical do que no grupo livre de cárie. O estudo também mostrou que os níveis de sCD foram significativamente reduzidos após o tratamento endodôntico. Portanto, níveis aumentados de sCD14 podem ser considerados um marcador de inflamação.

Objective To assess the diagnostic and prognostic value of measuring presepsin in patients with acute respiratory distress syndrome (ARDS).Methods Plasma prsepsin was collected from 81 patients with ARDS,27 patients with cardiogenic pulmonary edema (CPE) and 20 healthy volunteers at enrollment.Levels of presepsin were measured using the PATHFAST(R) analysis system based on a chemiluminescent enzyme immunoassay (CLEIA).The differences of plasma prsepsin were compared between different groups.The 28-day mortality were followed in ARDS patients,and the characteristics of the surviors and non-surviors were compared.Results ARDS patients had significantly higher median levels of presepsin compared to CPE patients [926.89 (485.41-2 662.32)pg/mL vs.376.21 (247.16-568.52) pg/mL,P＜0.001] at enrollment.The difference between infected and non-infected ARDS patients did not showed statistical significance [(934.74 (456.44-3 322.51) pg/mL vs.798.12 (485.41-2 561.40) pg/mL,P--0.079).In ARDS patients,the presepsin levels of non-survivors was significantly higher than that of survivors [3 158.3 (963.91-4 489.33) pg/mL vs.729.09 (398.05-1 467.24) pg/mL,P＜0.001],and multivariate Logistic regression showed that presepsin (OR =1.51,P =0.027) was the independent predictor for 28-day mortality in ARDS patients with acute lung injury (ALI).Conclusions Presepsin was an effective indicator in diagnosing ARDS,and it also was a strong prognostic marker for short-term mortality in ARDS.
ABSTRACT
Objective To evaluate the predictive value of serum presepsin (sCD14-ST) for septic myocardial depression (SMD) in patients with severe sepsis or septic shock.Methods This was a prospective cohort study.A total of 84 patients with severe sepsis or septic shock were monitored by pulse indicator continuous cardiac output (PiCCO) system and divided into myocardial depression group (cardiac function index [CFI]0.05).There were 24 cases died in myocardial depression group.The mortality of myocardial depression group was significantly higher than that of non-depression group (64.9% vs 42.6%, χ2=4.132, P =0.042).The serum levels of sCD14-ST at day 1 and day 3 in myocardial depression group were significantly higher than those in non-myocardial depression group (both P<0.01).sCD14-ST levels in both groups showed downtrend.The serum level of sCD14-ST in non-survival group was significantly higher than that in survival group (P<0.01).Conclusions Myocardial depression is common in patients with severe sepsis and septic shock.High serum level of sCD14-ST is correlated with myocardial depression to some extent, but not an independent predictor.The combination of sCD4-ST, BNP and TNF-α can improve the predictive value for myocardial depression.
ABSTRACT
AIM To investigate the effects of Shuxuening Injection (Ginkgo biloba leaf extract) on serum lactic acid (Lac),soluble CD14-st (Presepsin) and nitric oxide synthase (NOS) levels in sepsis patients.METHODS One hundred and eight patients with sepsis treated by routine treatment in our hospital from Jan.2014 to Oct.2016 were randomly divided into two groups,control group and Shuxuening group (therapy group).Two weeks were one therapeutic course.Before the treatment (the onset of patients within 3 hours),at 6 hours and 5 days after the treatment,Lac and Presepsin levels were detected,and the changes of nitric oxide (NO),NOS,inducible nitric oxide synthase (iNOS) and sequential organ failure assessment (SOFA) score were observed.Incidence of major adverse cardiac events (MACE) and 28-day survival were recorded at the same time.RESULTS Before the treatment,there were no significant differences in SOFA score and the levels of Lac,Presepsin,NO,NOS and iNOS between the two groups (P ＞ 0.05).Six hours after the treatment,the levels of Lac and Presepsin in the therapy group were lower than those in the control group (P ＜ 0.05),both the two groups had lower levels of Lac and Presepsin than those before the treatment (P ＜ 0.05);five days after the treatment,the levels of Lac and Presepsin in the two groups were lower than those at 6 hours after the treatment (P ＜ 0.05),the levels of Lac and Presepsin in the therapy group were lower than those in the control group (P ＜ 0.05).The SOFA score,NO,NOS and iNOS levels after the treatment in the therapy group were lower than those in the control group (P ＜ 0.05).The levels of Lac and Presepsin in sepsis patients were positively correlated with SOFA score (r =0.245,0.261,P =0.011,0.006).The patients in the therapy group had lower incidence of MACE and 28-day mortality rate than those in the control group (P ＜ 0.05).CONCLUSION The therapeutic effect of Shuxuening Injection combined with routine treatment on sepsis patients is superior to that of routine treatment,which can improve the prognosis of patients to a certain extent.

ABSTRACT
Objective To investigate the relationship between soluble CD14-st (Presepsin)and assessment,prognosis in patients with acute paraquat poisoning (APP).Methods A total of 82 patients with APP treated in Emergency Department of Harrison International Peace Hospital Affiliated to Hebei Medical University from January 2013 to January 2016 were divied into three groups:mild poisoning group (n =20),moderate poisoning group (n =36)and severe poisoning group (n =26).According to the outcomes,patients were divided into survivor group (n =28)and non-survivor group (n =54).Another 50 healthy subjects were selected as control group.In control group,samples of 3 mL venous blood from 50 healthy subjects were collected for laboratory examination.Samoles of 10 mL venous blood from all patients were collected before and 72 hours,7 days after treatment to detect presepsin,C reactive protein (CRP), tumor necrosis factor α(TNF-α),interleukin-6 (IL-6)and interleukin-10 (IL-10).Before and 72 hours, 7 days after treatment,the change of Acute physiology and chronic health evaluation (APACHE)Ⅱscore and the outcomes in 28 days were observed.The variance analysis of repeated measures was used for comparison among multiple groups,and the t test was used to compare changes of detected biomarkers between two groups,and the outcomes in 28 days between two groups were compared with chi square test. Pearson correlation test was used to analyze the correlation between Presepsin in patients with APP and the survival rate.Results APACHE Ⅱ scores and the serum level of prespsin,CRP,TNF-α,IL-6 at admission and 72 hours,7 days after treatment in three poisoning groups were significantly increased compared with control group,IL-10 were decreased compared with control group (P <0.05 ),and there were significant differences in those biomarkers between moderate group and mild group,and between severe group and mild group,moderate group (P <0.05).At admission,72 h,7 d after admission,APACHEⅡscore and the serum levels of presepsin,CRP,TNF-α,IL-6 in non-survivor group were higher than those in survivor group,and IL-10 in non-survivor was lower than that in survivor group (P <0.05).The mortality rates of these 3 groups were 25.00%,69.44% and 92.31%,demonstrating significant differences among three groups (P <0.05).The AUCs were 0.862 and 0.731 for presepsin and APACHEⅡscore respectively at admission.The predictive capability of presepsin for 28-day mortality was superior over that of APACHEⅡscore (P <0.05).The level of serum presepsin in patients with APP was negatively correlated with the survival rate (r =-0.285,P =0.009).Conclusions The detection of prespsin has important clinical value in the severity assessment and prognosis in patients with APP.It is an important guidance for early therapeutic strategy.
ABSTRACT
Objective To study the changes and significance of sCD14 in inflammatory response of patients with gouty arthritis.Methods CD14 mRNA was measured using quantitative real-time PCR in peripheral blood mononuclear cells (PBMCs).The expression of CD14 mRNA in PBMCs was compared between patients with acute gouty arthritis (AGA)(n =31)and non-acute gouty arthritis (NAGA)(n =23)and healthy controls (HC)(n =20).β-actin was selected as the internal control.The protein expressions of sCD14,IL-1βand TNF-αwere measured using enzyme linked immunosorbent assay (ELISA) in patients’ plasma.The protein expression of CRP was measured using immunoturbidimetry in patients’ plasma. Routine blood and blood biochemistry indexes were measured by routine blood analyzer and blood biochemistry analyzer of patients with AGA,NAGA and HC.We analyzed the correlation between CD14 mRNA,sCD14 protein expression and each clinical indicator.Results When compared with that in AGA group,the mRNA expression of CD14 increased significantly in PBMCs of HC patients (P < 0.05 ).When compared with that in HC and NAGA patients,the protein expression of sCD14 increased significantly in the plasma of AGA patients (P <0.01).The protein expression of sCD14 was significantly lower in the plasma of NAGA than in HC (P <0.05).The protein expression of sCD14 increased significantly in the plasma of AGA compared with HC and NAGA (P < 0.01 ).When compared with those in HC,the protein expressions of IL-1β and TNF-α increased significantly in the plasma of AGA and NAGA (P < 0.01 ).When compared with that in NAGA,the protein expression of IL-1βincreased significantly in plasma of AGA (P <0.01). The indexes of WBC increased significantly in AGA compared with HC (P <0.01),and WBC increased significantly in NAGA compared with HC (P <0.05).The indexes of GR and MO increased significantly in AGA compared with HC (P <0.05),and MO increased significantly in AGA compared with NAGA (P < 0.05 ).The indexes of UA increased significantly in AGA and NAGA compared with HC (P <0.01).There was a positive correlation between CD14 mRNA expression and IL-1β in PBMCs in AGA group (r s =0.362,P =0.045).A positive correlation was found between GR and the protein expression of sCD14 in NAGA patients’plasma (r s = 0.397,P = 0.030 ). Conclusion The dysregulated expressions of CD14 mRNA in PBMCs and sCD14 protein in GA show that sCD14 may play a significantly regulatory role in inflammatory reaction.

ABSTRACT
@#ObjectiveTo explore changes of lipopolysaccharide (LPS), lipopolysaccharide-binding protein (LBP), bactericidal/permeability-increasing protein (BPI), soluble CD14 (sCD14) in blood of cirrhosis patients and their clinical significance.MethodsSerum samples of 45 cirrhosis patients were detected with chromogenic limulus amebocyte lysate assay for LPS and detected with ELISA for LBP, BPI and sCD14. While, serum samples of 15 normal subjects were used as controls.ResultsLevels of LPS, LBP, BPI and sCD14 in blood of cirrhosis patients with liver function being grade A, B and C were significantly higher than that in normal subjects. Also, those indexes fore mentioned were obviously higher in died cirrhosis patients than that in survived cirrhosis patients.Conclusion High levels of LBP, LPS and relative deficiency of BPI in cirrhosis patients accompanied with intestinal endotoxemia (IETM) may significantly increase the sensitivity of body to endotoxin.
