ABSTRACT
Objective The changes and risk factors of FeNO, CRP and PCT in patients with bronchial asthma complicated with sleep apnea syndrome (SAS) in Shanghai area were analyzed to provide theoretical basis for the prevention and treatment of SAS in patients with bronchial asthma. Methods A total of 436 patients with bronchial asthma admitted to our hospital from January 2019 to June 2022 were selected and divided into control group and experimental group according to whether SAS occurred during hospitalization. The experimental group was divided into three subgroups according to the apnea hypopnea index (AHI) values: mild group (AHI>15 times /h or 15 times /h or 28 kg/m2(OR=5.629),allergic rhinitis(OR=6.166)and neck circumference>40 cm(OR=5.265)were independent risk factors for SAS in patients with bronchial asthma(P<0.05);Pearson correlation analysis showed that AHI was positively correlated with serum FeNO,CRP and PCT levels in patients with bronchial asthma and SAS(r=0.471,0.436,0.502,P<0.05). Conclusions Patients with old bronchial asthma in Shanghai area have a higher risk of SAS, and the severity of the disease is positively correlated with the levels of FeNO, CRP and PCT. In particular, obese patients with allergic rhinitis should be given early intervention to reduce the risk of SAS.
ABSTRACT
Objective To analyze the prognosis of children with severe mycoplasma pneumonia (MPP) and its correlation with serum SAA, PCT and SF levels, so as to provide a basis for evaluating the prognosis of children with MPP. Methods A total of 273 children with MPP admitted to our hospital from January 2020 to December 2020 were divided into mild MPP children (n=187) and severe MPP children (n=86) according to the severity of their disease. According to the prognosis, children with severe MPP were divided into survival group (n=65) and death group (n=21). Serum SAA, PCT and SF levels were determined. Pearson correlation analysis was used to analyze the correlation between serum SAA, PCT and SF levels and APACHE ⅱ score. ROC curve was used to analyze the predictive value of serum SAA, PCT and SF levels for poor prognosis of children with severe MPP. Results The levels of serum SAA, PCT and SF and APACHE II score in children with severe MPP were significantly higher than those in children with mild MPP (P<0.05). Serum SAA, PCT and SF levels and APACHE II score in death group were significantly higher than those in survival group (P<0.05). Pearson correlation analysis showed that APACHE II score was positively correlated with serum SAA, PCT and SF levels (r =0.474,0.519,0.446,P<0.05). The AUC, sensitivity and specificity of combined ROC curve analysis to predict the prognosis of severe MPP were 0.871, 85.9% and 93.6% respectively, which were higher than those of SAA, PCT and SF alone. Conclusion SAA, PCT and SF are closely related to the prognosis of severe MPP, and can be used as potential markers to predict poor prognosis of severe MPP children.
ABSTRACT
【Objective】 To compare the bioactive ingredients in activated platelet-rich plasma (PRP) from cord blood and adult blood, explore its reasonable indicators reflecting the inflammatory regulation ability, in order to guide the preparation. 【Methods】 PRP was prepared and activated from 63 healthy adults (31 males, 32 females) and 61 neonates (30 males, 31 females), and 20 cytokines were measured using Luminex technology for assessing the age- and sex-based bioactive differences of PRP. High-sensitivity C-reactive protein(hs-CRP), procalcitonin and MMPs/TIMPs from each sample were measured for their correlations with the 10 inflammation-related cytokines. 【Results】 The activated cord blood PRP released 10 growth factors and chemokines more than the adult blood PRP, whereas IGF-1, HGF and 8 pro-inflammatory cytokines lower than the latter. Most cytokines of adult PRP were more in females than in males (P<0.05), except for IGF-1 and HGF, which showed no difference by gender. Compared with hs-CRP and PCT, MMPs/TIMPs ratio was more closely related with the inflammation-related cytokines, which can reflect the inflammatory regulation of PRP. 【Conclusion】 Due to the lower immunocompetence and no age or gender disturbance, cord blood PRP has the rational MMPs/TIMPs ratio and more cytokines which promote the inflammation and wound healing.
ABSTRACT
Introduction: Sepsis has a death rate of ?25% globally and its clinical treatment presents an important clinical challenge. The Acute Physiology and Chronic Health Evaluation II (APACHE II) is the standard method for assessing sepsis. Serum PCT level can be increase in case of sepsis. With this background, the present research is aimed to study the survival among the sepsis cases and correlate them with serum procalcitonin levels, APACHE II Score and other risk factors. Methodology: The study was conducted among 75 cases diagnosed having sepsis admitted in medical ICU. APACHE II score, serum procalcitonin (PCT) and other investigation were carried out along with clinical history and examination. Data were analysed using epi-info software. Results: The cases fatality rate of sepsis cases in medical intensive care unit in our hospital was 37.3%. The mortality rate was significantly higher patients with comorbidities, especially cases with respiratory or CNS involvement. The serum PCT levels were significantly higher in the group of non survivors as compared to group of survivors. Higher APACHE II score associated with higher mortality. Serum PCT levels go on increasing along the spectrum of sepsis. A PCT level was significantly hire in culture positive cases compare to sterile cases. Conclusion: From this study we conclude that serum PCT level is useful investigation in sepsis cases to predict mortality

It has higher sensitivity than other conventional stress indicators like S-CRP, CRP, IL-6 and PCT.
ABSTRACT
This study aimed to investigate the diagnostic value of heparin-binding protein (HBP) in the cerebrospinal fluid of children with purulent meningitis (PM). This study included 118 children with PM diagnosed at our hospital from January 2018 to January 2020, 110 children with viral meningitis (VM) and 80 children with suspected meningitis who were ruled out by cerebrospinal fluid (CSF) analysis during the same period. HBP and white blood cell (WBC) count in the CSF, and inflammatory factors, including C-reactive protein (CRP), tumor necrosis factor (TNF)-α, and procalcitonin (PCT), were measured. Receiver-operator characteristic curves were used to analyze the predictive value of HBP, CRP, PCT, and TNF-α levels in the diagnosis of PM by CSF analysis. HBP levels in the CSF of children with PM were higher, while the CRP and serum PCT and TNF-α levels were elevated in all groups (P<0.05). In addition, HBP levels in the CSF were more accurate for the diagnosis of PM than traditional diagnostic indexes. HBP levels in the CSF can be used as an important reference for early diagnosis of PM.

Fluid Attenuated Inversion Recovery (FLAIR) MRI of brain is sensitive in detecting parenchymal lesions, extra axial lesions such as meningoencephalitis, and leptomeningeal tumoural disease. We wanted to compare gadolinium enhanced T2W FLAIR with PC-T1W (post contrast T1 weighted) MRI sequence in detection and evaluation of meningeal and parenchymal lesions. We also wanted to compare gadolinium enhanced T1W FLAIR with PC-T1W MRI sequence in detection and evaluation of meningeal and parenchymal lesions.METHODS65 patients with clinical diagnosis of cerebral meningitis or intracranial tumoural disease were scanned on 1.5 T 16 channel MRI scanner. A standard brain protocol was used, followed by PC-T1W and post contrast FLAIR, with PC-T1W MR preceding post contrast FLAIR. Images were assessed independently by 2 radiologists who marked the technique they thought had made the meningeal and parenchymal disease more conspicuous. In case of disagreement the radiologists made a consensus determination.RESULTSPC-T2 FLAIR showed better enhancement in 100% of the intra axial lesions compared to PC-T1W images. However, PC-T1 FLAIR showed better enhancement than PC-T1W images in only 81% of the same. PC-T2 FLAIR showed better enhancement in 100% of the extra-axial lesions compared to PC-T1W images. However, PC-T1 FLAIR showed less enhancement in all the extra axial lesions.CONCLUSIONSContrast enhanced T2 FLAIR MRI showed better enhancement of parenchymal and meningeal lesions. PC-T2 FLAIR detected more number of lesions when compared to PC-T1W, aided better delineation of extra-axial mass lesions due to superior enhancement, and had a better demarcated dural tail. Post-contrast T2 FLAIR images should be included in routine protocol for contrast MRI brain study.
ABSTRACT
Background: Science and technology are two desirable elements for the economic and social development of a country. Biotechnology has a particularly important potential for economic development. Nevertheless, patent production in Latin America remains underdeveloped, which creates the need to analyze its trend and the efforts made to promote patent production. Therefore, the purpose of this study was, on the one hand, to determine trends in biotechnology-related PCT (Patent Cooperation Treaty) applications in Chile, Mexico, Argentina, Brazil, and Cuba from 1999 to 2015, and, on the other hand, to determine whether there is a relationship between the gross domestic expenditure on research and experimental development as a percentage of gross domestic product (GERD/GDP) and PCT applications for biotechnological inventions from 2007 to 2015 (in this case, the period under study was limited from 2007 to 2015, due to data availability for GERD/GDP in the five selected countries). Results: The first part of this study shows that the growth in biotechnology PCT applications has been moderate and gradual and the trend was fitted to a linear model. The second set of results shows that GERD/GDP is associated with biotechnology-related PCT applications issued during the study period with a significance level of α = 0.01. Conclusions: Even though results indicate a gradual and modest progress, it is necessary that these five representative Latin American nations continue acting toward the protection of intellectual property in the area of biotechnology, especially by configuring strategies for further progress based on investments on research and development.

ABSTRACT
Objective: To investigate the value of joint detection of soluble triggering receptor expresses on myeloid cells-1(sTREM-1) and procalcitonin (PCT) in the early diagnosis of children with sepsis. Methods: 78 children with sepsis were selected into the sepsis group, 23 children with common infection were selected into the normal infection group. In addition, 25 healthy children selected into the health control group. The levels of sTREM-1, PCT, and C reactive protein (CRP) among the three groups were compared, respectively. And then, the sepsis group were further divided into general sepsis subgroup (32 cases), severe sepsis subgroup (26 cases) and septic shock subgroup (20 cases) according to the degree of sepsis. The levels of sTREM-1, PCT and CRP among the three sepsis subgroups were compared. And the receiver operating characteristic (ROC) curve was adopted to analyze the value that diagnosed children with sepsis by using the three indicators. Results: The levels of sTREM-1, PCT and CRP of sepsis group were significantly higher than those of common infection group and health control group (t=22.071, t=21.508, t=17.870, t=55.167, t=52.070, t=30.359, P<0.05). The differences of sTREM-1 and PCT among various sepsis subgroups were significant (H=22.082, H=39.449, P<0.05), but the difference of CRP level between septic shock subgroup and severe sepsis subgroup was no significant. As the compared result of AUC of ROC of diagnosing sepsis, the AUC of sTREM-1 was maximum (0.88), and its 95% confidence interval (CI) was 0.78-0.98. At the optimum cutoff value of sTREM-1, the sensitivity and specificity were 83.33% and 68%, respectively, and they were higher than those of PCT and CRP, respectively. Besides, the cutoff values of sTREM-1 and PCT were used as standard to carry out joint diagnosis for children with sepsis, and the sensitivity and specificity were 91.03% and 64%, respectively, at this joint diagnosis. Conclusion: The joint detection of sTREM-1 and PCT has higher sensitivity in the early diagnosis of children with sepsis and it has a certain clinical application value.
ABSTRACT
To avoid the abuse and misuse of antibiotics, procalcitonin (PCT) and C-reactive protein (CRP) have been used as new approaches to identify different types of infection. Multiple databases were adopted to search relevant studies, and the articles that satisfied the inclusion criteria were included. Meta-analyses were conducted with Review Manager 5.0, and to estimate the quality of each article, risk of bias was assessed. Eight articles satisfied the inclusion criteria. The concentrations of both PCT and CRP in patients with bacterial infection were higher than those with non-bacterial infection. Both PCT and CRP levels in patients with G− bacterial infection were higher than in those with G+ bacterial infection and fungus infection. In the G+ bacterial infection group, a higher concentration of CRP was observed compared with fungus infection group, while the difference of PCT between G+ bacterial infection and fungus infection was not significant. Our study suggested that both PCT and CRP are helpful to a certain extent in detecting pneumonia caused by different types of infection.
