OBJECTIVE: To analyze the value of procalcitonin (PCT) in the diagnosis of perioperative infection associated with implants in patients with primary hip arthroplasty. METHODS: A retrospective study was conducted on 150 patients who underwent primary hip arthroplasty from June 2018 to June 2020, including 86 males and 64 females, aged from 47 to 77 years old with an average of (57.04±7.43) years. All patients with primary hip arthroplasty were divided into infection group and non infection group according to whether there was infection after operation. Blood samples were collected from the elbow vein before operation (D0) and on the 4, 6, 8 days after operation(D4, D6 and D8) respectively to detect the serum PCT level and white blood cell count (WBC) level. RESULTS: Among 150 patients with primary hip arthroplasty, 34 patients with postoperative infection were in the infection group, and 116 patients without postoperative infection were in the noninfection group. In the infection group, there were 19 cases of superficial surgical site infection(55.88%, 19/34), 9 cases of urinary tract infection (26.47%, 9/34), and 6 cases of pneumonia(17.65%, 6/34). After bacterial culture in the infection group, there were 9 cases of Staphylococcus aureus, 3 cases of Escherichia coli, 3 cases of Staphylococcus epidermidis, 3 cases of Streptococcus constellation, 3 cases of Candida albicans, 6 cases of Klebsiella pneumoniae, 2 cases of Escherichia coli and Streptococcus agalactis, 3 cases of coagulase invisible staphylococcus and Burkholderia cepacia, 2 cases of Escherichia coli, Enterococcus faecalis and Pseudomonas aeruginosa. There was no significant difference in PCT levels between two groups in D0(P=0.081), D4(P=0.069) and D6(P=0.093), but there was significant difference in D8(P=0.007). There was no significant difference in WBC between two groups at any time point(P>0.05). The results of receiver operating characteristic curve(ROC) showed that the AUC of PCT diagnosis was 0.978[95%CI(0.933, 1.022)] and that of WBC was 0.562[95%CI(0.398, 0.726)], PCT was an important predictor of infection after primary hip arthroplasty(AUC>0.9). When the critical value was 0.526 ng/ml, the sensitivity and specificity of PCT diagnosis are 36% and 100%, respectively, WBC was not a significant predictor of infection after primary hip arthroplasty (0.59/L, the sensitivity and specificity were 64% and 44%, respectively. CONCLUSION PCT has a high specificity for perioperative infection in patients with primary hip replacement, and it is a promising diagnostic index for infection.

BACKGROUND: We performed this study to identify factors related to intact incretin levels in patients with type 2 diabetes mellitus (T2DM). METHODS: We cross-sectionally analyzed 336 patients with T2DM. Intact glucagon-like peptide 1 (iGLP-1) and intact glucose-dependent insulinotropic polypeptide (iGIP) levels were measured in a fasted state and 30 minutes after ingestion of a standard mixed meal. The differences between 30 and 0 minute iGLP-1 and iGIP levels were indicated as ΔiGLP-1 and ΔiGIP. RESULTS: In simple correlation analyses, fasting iGLP-1 was positively correlated with glucose, C-peptide, creatinine, and triglyceride levels, and negatively correlated with estimated glomerular filtration rate. ΔiGLP-1 was positively correlated only with ΔC-peptide levels. Fasting iGIP showed positive correlations with glycosylated hemoglobin (HbA1c) and fasting glucose levels, and negative correlations with ΔC-peptide levels. ΔiGIP was negatively correlated with diabetes duration and HbA1c levels, and positively correlated with Δglucose and ΔC-peptide levels. In multivariate analyses adjusting for age, sex, and covariates, fasting iGLP-1 levels were significantly related to fasting glucose levels, ΔiGLP-1 levels were positively related to ΔC-peptide levels, fasting iGIP levels were related to fasting C-peptide levels, and ΔiGIP levels were positively related to ΔC-peptide and Δglucose levels. CONCLUSION: Taken together, intact incretin levels are primarily related to C-peptide and glucose levels. This result suggests that glycemia and insulin secretion are the main factors associated with intact incretin levels in T2DM patients.

BACKGROUND: In Korea, the costs associated with self-monitoring of blood glucose (SMBG) for patients with type 2 diabetes mellitus (T2DM) under insulin treatment have been reimbursed since November 2015. We investigated whether this new reimbursement program for SMBG has improved the glycemic control in the beneficiaries of this policy. METHODS: Among all adult T2DM patients with ≥3 months of reimbursement (n=854), subjects without any changes in anti-hyperglycemic agents during the study period were selected. The improvement of glycosylated hemoglobin (HbA1c) was defined as an absolute reduction in HbA1c ≥0.6% or an HbA1c level at follow-up < 7%. RESULTS: HbA1c levels significantly decreased from 8.5%±1.3% to 8.2%±1.2% during the follow-up (P < 0.001) in all the study subjects (n=409). Among them, 35.5% (n=145) showed a significant improvement in HbA1c. Subjects covered under the Medical Aid system showed a higher prevalence of improvement in HbA1c than those with medical insurance (52.2% vs. 33.3%, respectively, P=0.012). In the improvement group, the baseline HbA1c (P < 0.001), fasting C-peptide (P=0.016), and daily dose of insulin/body weight (P=0.024) showed significant negative correlations with the degree of HbA1c change. Multivariate analysis showed that subjects in the Medical Aid system were about 2.5-fold more likely to improve in HbA1c compared to those with medical insurance (odds ratio, 2.459; 95% confidence interval, 1.138 to 5.314; P=0.022). CONCLUSION: The reimbursement for SMBG resulted in a significant improvement in HbA1c in T2DM subjects using insulin, which was more prominent in subjects with poor glucose control at baseline or covered under the Medical Aid system.

OBJECTIVETo investigate the effects of vasoactive intestinal peptide (VIP) on the airway inflammation and its regulatory effect on Th17/Treg imbalance in asthmatic mice.

METHODSA total of 30 BALB/c mice were equally and randomly divided into three groups: control, asthma, and VIP. An acute asthmatic mouse model was established by sensitization and challenge with ovalbumin (OVA). The control group received normal saline instead of OVA. Before the challenge with OVA, the VIP group was administered VIP (20 μg/mL) by aerosol inhalation for 30 minutes. The bronchoalveolar lavage fluid (BALF) and the lung tissue were collected from mice. The pathological changes in the lung tissue were observed by hematoxylin and eosin staining. The levels of Th17/Treg-related cytokines in BALF were measured by enzyme-linked immunosorbent assay. The expression of retinoid-related orphan receptor gamma t (RORγt) and forkhead box P3 (Foxp3) were measured by real-time fluorescence quantitative PCR and immunohistochemistry.

RESULTSThe histopathological results showed that the VIP group had milder symptoms of airway inflammation than the asthma group. The level of IL-17 in BALF in the asthma group was significantly higher than that in the control group and the VIP group (P<0.01), but the level of IL-17 in the control group was significantly lower than that in the VIP group (P<0.01). The level of IL-10 in BALF in the asthma group was significantly lower than that in the control group and the VIP group (P<0.01, but the level of IL-10 in the VIP group was significantly higher than that in the control group (P<0.01). The asthma group showed significantly higher expression levels of RORγt mRNA and protein in the lung tissue and significantly lower expression levels of Foxp3 mRNA and protein than the control group (P<0.01). The VIP group had significantly lower expression levels of RORγt mRNA and protein in the lung tissue and significantly higher expression levels of Foxp3 mRNA and protein than the asthma group (P<0.05).

CONCLUSIONSThe Th17/Treg imbalance may be closely related to the airway inflammation in asthmatic mice. VIP can improve airway inflammation by regulating the Th17/Treg imbalance in asthmatic mice.

OBJECTIVETo investigate the changes in plasma gelsolin (pGSN) levels in severe burn patients with sepsis, and to evaluate the prognosis of patients when combined with other related clinical indexes.

METHODSSixty-five severe burn patients with sepsis hospitalized from June 2013 to June 2015 conforming to the study criteria were divided into death group (n=24) and survival group (n=41) according to the clinical outcome on post sepsis diagnosis day (PSD) 28. The pGSN levels of patients were determined on PSD 1, 3, 7, and 14 with double antibody sandwich enzyme-linked immunosorbent assay. The serum level of C-reactive protein (CRP), serum level of procalcitonin, lactate level of arterial blood, Acute Physiology and Chronic Health Evaluation (APACHE) II score, and Sequential Organ Failure Assessment (SOFA) score were determined or recorded on PSD 1. Data were processed with repeated measurement analysis of variance, t test, and chi-square test. On PSD 1, the pGSN level, serum level of CRP, serum level of procalcitonin, lactate level of arterial blood, APACHE II score, and SOFA score of 65 patients were collected to screen the independent risk factors related to death with single factor and multi-factor Logistic regression analysis. Receiver operating characteristic (ROC) curves of the independent risk factors related to death were plotted to evaluate the predictive power for death in 65 patients.

RESULTS(1) The pGSN levels of patients in death group on PSD 1, 3, 7, and 14 were respectively (146±44), (85±24), (28±7), and (19±4) mg/L, obviously lower than those in survival group [(287±82), (179±51), (196±56), and (249±67) mg/L, with t values from 1.735 to 4.304, P<0.05 or P<0.01]. (2) The serum level of CRP, serum level of procalcitonin, lactate level of arterial blood, APACHE II score, and SOFA score of patients in death group on PSD 1 were respectively (56±7) mg/L, (12.54±0.82) μg/L, (2.74±0.27) mmol/L, (24.3±2.4) points, and (11.43±0.57) points, significantly higher than those in survival group [(35±4) mg/L, (2.38±0.16) μg/L, (1.83±0.12) mmol/L, (15.0±1.5) points, and (7.22±0.23) points, with t values from 1.902 to 3.883, P<0.05 or P<0.01]. (3) Multi-factor Logistic regression analysis showed that the pGSN level (odds ratio: 6.83, 95% confidence interval: 4.33-10.25, P<0.01) and APACHE II score (odds ratio: 5.27, 95% confidence interval: 2.28-9.16, P<0.01) were the independent risk factors related to death in 65 patients on PSD 1. (4) The total areas under the ROC curves of pGSN level and APACHE II score for predicting death of 65 patients on PSD 1 were respectively 0.89 and 0.86, and 142 mg/L and 21 points were respectively chosen as the optimal threshold values, with sensitivity of 87% and 83% and specificity of 86% and 89%.

CONCLUSIONSFor severe burn patients with sepsis, lowering of pGSN level and elevation of APACHE II score are obviously correlated with increase in case fatality rates. Monitoring the dynamic changes in pGSN level and APACHE II score during the early stage may be useful to predict the prognosis of severe burn patients with sepsis.

BACKGROUND: Amino-terminal pro-B type natriuretic peptide (NT-proBNP) is a well-established prognostic factor in heart failure (HF). However, numerous causes may lead to elevations in NT-proBNP, and thus, an increased NT-proBNP level alone is not sufficient to predict outcome. The aim of this study was to evaluate the utility of two acute response markers, high sensitivity C-reactive protein (hsCRP) and heart-type fatty acid binding protein (H-FABP), in patients with an increased NT-proBNP level. METHODS: The 278 patients were classified into three groups by etiology: 1) acute coronary syndrome (ACS) (n=62), 2) non-ACS cardiac disease (n=156), and 3) infectious disease (n=60). Survival was determined on day 1, 7, 14, 21, 28, 60, 90, 120, and 150 after enrollment. RESULTS: H-FABP (P<0.001), NT-proBNP (P=0.006), hsCRP (P<0.001) levels, and survival (P<0.001) were significantly different in the three disease groups. Patients were divided into three classes by using receiver operating characteristic curves for NT-proBNP, H-FABP, and hsCRP. Patients with elevated NT-proBNP (≥3,856 pg/mL) and H-FABP (≥8.8 ng/mL) levels were associated with higher hazard ratio for mortality (5.15 in NT-proBNP and 3.25 in H-FABP). Area under the receiver operating characteristic curve analysis showed H-FABP was a better predictor of 60-day mortality than NT-proBNP. CONCLUSIONS: The combined measurement of H-FABP with NT-proBNP provides a highly reliable means of short-term mortality prediction for patients hospitalized for ACS, non-ACS cardiac disease, or infectious disease.

PURPOSE: In the gastric mucosa of Helicobacter pylori (H. pylori)-infected patients with gastritis or adenocarcinoma, proliferation of gastric epithelial cells is increased. Hyperproliferation is related to induction of oncogenes, such as β-catenin and c-myc. Even though transcription factors NF-κB and AP-1 are activated in H. pylori-infected cells, whether NF-κB or AP-1 regulates the expression of β-catenein or c-myc in H. pylori-infected cells has not been clarified. The present study was undertaken to investigate whether H. pylori-induced activation of NF-κB and AP-1 mediates the expression of oncogenes and hyperproliferation of gastric epithelial cells. MATERIALS AND METHODS: Gastric epithelial AGS cells were transiently transfected with mutant genes for IκBα (MAD3) and c-Jun (TAM67) or treated with a specific NF-κB inhibitor caffeic acid phenethyl ester (CAPE) or a selective AP-1 inhibitor SR-11302 to suppress activation of NF-κB or AP-1, respecively. As reference cells, the control vector pcDNA was transfected to the cells. Wild-type cells or transfected cells were cultured with or without H. pylori. RESULTS: H. pylori induced activation of NF-κB and AP-1, cell proliferation, and expression of oncogenes (β-catenein, c-myc) in AGS cells, which was inhibited by transfection of MAD3 and TAM67. Wild-type cells and the cells transfected with pcDNA showed similar activities of NF-κB and AP-1, proliferation, and oncogene expression regardless of treatment with H. pylori. Both CAPE and SR-11302 inhibited cell proliferation and expression of oncogenes in H. pylori-infected cells. CONCLUSION: H. pylori-induced activation of NF-κB and AP-1 regulates transcription of oncogenes and mediates hyperproliferation in gastric epithelial cells.

OBJECTIVETo evaluate the role of serum level of procalcitonin (PCT), C-reactive protein (CRP), erythrocyte sedimentation rate (ESR), and white blood cell count (WBC) as predictors in postoperative early infectious complications with fever after posterior lumbar internal fixation (PLIF).

METHODSA retrospective study was conducted from January 2012 to January 2014. Fifty-two patients with fever in the early stage(within 10 days) after the PLIF were collected in the study. They were divided into infection group and non-infection group (group A and group B) according to the results of postoperative blood culture. There were 26 patients in group A and 32 patients in group B. The values of PCT, CRP, ESR, and WBC count were compared and analyzed between two groups.

RESULTSThe values of PCT, CRP, and ESR in group A were higher than those of group B. Meanwhile, CRP and ESR in group B were still higher than the normal range. Among the 26 patients with infections (group A), PCT was superior to CRP and ESR, had a good ability in discriminating different kinds of postoperative infections. The area under the ROC curve of serum PCT levels was the largest (CI 95% was 0.81 to 0.98) in the indexs; and ROC curve of WBC count was no statistically significant. When the cut off points of each predictors were evaluated, the higher sensitive was CRP and reached at 90.27% and the higher specific was ESR and reached at 88.50%.

CONCLUSIONFor the patients with fever at the early stage after the PLIF should be paid attention and reasonable choosing predictors are helpful to identify postoperative infection in the early stage. The CRP and ESR may be influenced by the surgery, and the PCT level is helpful to differentiate infection type.

OBJECTIVETo evaluate the predictive value of serum iron level for in-hospital acute heart failure (AHF) after acute ST-elevated myocardial infarction (STEMI).

METHODSThis retrospective study involved 287 patients with STEMI stratified by quartiles of admission serum iron concentration. The incidence of AHF was assessed by serum iron quartiles. We evaluated the association of serum iron levels with B-type natriuretic peptide (BNP), cardiac troponin I (cTnI), and high-sensitivity C-reactive protein (hs-CRP) levels on admission, and analyzed the correlation of serum iron levels with in-hospital AHF, death, and duration of hospital stay.

RESULTSThe average serum iron level on admission of the 287 STEMI patients was 10.20 µmol/L (6.90-14.40 µmol/L), and the quartiles (Q) of serum iron levels were ≤6.90 µmol/L (Q(1)), 6.91-10.19 µmol/L (Q(2)), 10.20-14.39 µmol/L (Q(3)), and ≥14.40 µmol/L (Q(4)). The incidences of in-hospital AHF from Q(1) to Q(4) were 79.5%, 64.3%, 50.0% and 45.9%, respectively (P<0.001). Univariate logistic regression analysis showed that low admission serum iron level (Q(1)) was an independent predictor for in-hospital AHF (OR=3.358, 95%CI 1.791- 6.294, P<0.001), and multivariate logistic regression analysis showed a similar result (OR=2.316, 95%CI 1.205-4.453, P=0.012).

CONCLUSIONSA lower admission serum iron level is an independent predictor of AHF in STEMI patients during hospitalization.

OBJECTIVETo study the value of Pentraxin 3 (PTX3) in diagnosing the severity and cardiovascular function of the critically ill children. Method A total of 178 patients who were older than 28 days, with acute infection of respiratory or neurological system, excluding chronic or special disease, and admitted to the pediatric intensive care unit (PICU) of Hunan Children's Hospital from October 1, 2013 to April 30, 2014 were enrolled, including 102 male cases and 76 female cases. The ages ranged from 1 month to 13 years and 1 month, 78 of them were less than 1 year old ; 58 cases were between 1 to 3 years old; 42 cases were above 3 years old; 101 cases were diagnosed as respiratory system diseases, 77 cases had nervous system diseases. PTX3 was detected with enzyme-linked immunosorbent assay (ELISA) within 1 d after enrollment, at 3 days and 7 days, meanwhile, troponin, myocardial enzyme, brain-type natriuretic peptide (BNP), C-reactive protein (CRP), plasma calcitonin (PCT) and WBC etc. Were measured. According to the plasma PTX3 value which were measured within 24 h after enrollment the patients were divided into three groups: mildly elevated group (< 44 µg/L) 41 cases; moderately elevated group (44 - < 132 µg/L) in 66 cases; severely elevated group 71 cases (132 µg/L or higher). Those 178 patients were divided into 3 groups according to the degree of infection: non-sepsis group (78 cases), sepsis group (70 cases), severe sepsis group (30 cases), and in each group, those with heart failure were respectively 19 cases, 28 cases, 17 cases. Analysis of the plasma PTX3 expression changes in different clinical manifestations, different condition, different degrees of organ damages and prognosis for the patient. The continuous variables were analyzed with t-test, F-test, H-test, the categorical variables were analyzed with Chi-square test, and the correlation analysis was performed to calculate Pearson coefficients.

RESULTThe PTX3 value measured within 24 h after enrollment increased with the degree of infection (50. 4(35. 2,70. 4) µg/L; 175. 8 (99. 6, 309. 9) µg/L;419. 9 (168. 3, 468. 6) µg/L; H = 88. 345, P = 0. 000). PTX3 level gradually declined, while in severe sepsis group decreased slowly (P <0. 05); the area under the ROC curve of Plasma PTX3 was larger than that of other inflammatory markers such as CRP and PCT, white blood cells and neutrophils in the diagnosis of sepsis; while the former three are PTX3, PCT and CRP (the sensitivity and specificity respectively were 0. 77, 0. 68; 0. 66, 0. 6; 0. 47, 0. 55); the PTX3 value of the severely elevated group was significantly higher than those of the mildly and moderately elevated groups (P <0. 05). The proportion of having 3 or more organs failure increased as the PTX3 rising among the groups of mildly elevated group, moderately elevated group and severely elevated group (1(2. 4%), 4(6. 1%), 14(19. 7%) χ2 =16. 16,P = 0. 000); and in each group, the proportion of having good and poor prognosis for these three groups were different (33 (80.5%) and 8 (19. 5%), 35 (53%) and 31 (47%), 28 (39.4%) and 43 (60.6%), χ = 17. 663, P = 0. 000). The K-M curve for these three groups had statistically significant difference (χ2 = 7. 086, P = 0. 029). Those with heart failure had higher PTX3 value than those in non-heart failure at the same degree of infection. PTX3 value increased with myocardial enzyme (troponin, creatine kinase isoenzyme, BNP) levels. In the diagnosis of heart failure, the area under the ROC curve were respectively PTX3 0. 824; BNP 0. 772; CM-KB 0. 643; CNTIO. 671, the sensitivity and specificity were PTX3 0. 8, 0. 58; CK-MB 0. 56,0. 79; CTNI 0. 60,0. 69; BNP 0. 73, 0. 58. In terms of predicting the prognosis of sepsis with heart failure complications, the PTX3 value's area under ROC curve was larger than that of BNP (respectively 0. 844, 0. 472).

CONCLUSIONThe PTX3 is an objective biochemical marker in diagnosis of sepsis; it is helpful in assessment of severity and prognosis of sepsis; it also has a certain clinical value in the assessment of sepsis cardiovascular function damage.
