ABSTRACT

Objective To investigate the value of neutrophil CD64 combined with monocyte chemotactic protein 1 (MCP-1),interleukin-8 (IL-8) and interferon-inducible protein-10 (IP-10) in the clinical diagnosis of neonatal sepsis.Method Cases of neonatal sepsis from March 2015 to June 2016 in the department were chosen as sepsis group.35 neonates with non-infection diseases were selected as noninfection group and 40 healthy newborn infants were assigned as control group.The level of CD64 in blood were detected by flow cytometry,while the level of MCP-1,IL-8 and IP-10 of the serum in the three groups were detected by automatic biochemical analyzer.The differences between groups were compared by single factor ANOVA.The ROC curves of sepsis diagnosed by whole blood CD64,serum MCP-1,IL-8 and IP-10 were drew.Result The level of CD64,IL-8 and IP-10 of the neonatal blood in the sepsis group were significantly higher than that in the non-infection group (P < 0.05) and control group (P < 0.05).There were no significant difference between the sepsis group and non-infection group in MCP-1 (P > 0.05),but significantly higher than that in the control group (P < 0.05).The levels of serum MCP-1 and IP-10 in the non-infection group were significantly higher than those in the control group (P < 0.05),but there was no significant difference between the non-infection group and control group in CD64 and IL-8 (P >0.05).The optimal thresholds of blood CD64,MCP-1,IL-8 and IP-10 in the diagnosis of sepsis were 35.0 MFI,58.6 ng/L,60.3 ng/L,0.46 μg/L.The sensitivity and specificity of the diagnosis of sepsis were 92.8% and 90.6% in CD64,70.0% and 42.6% in MCP-1,78.5% and 68.0% in IL-8,72.8% and 54.6% in IP-10,97.1% and 94.6% when combined.Conclusion The combination test of CD64,MCP-1,IL-8 and IP-10 can improve the sensitivity and specificity of the diagnosis of sepsis.

ABSTRACT

Objective To investigate the significance of CD64 combined with C-reactive protein (CRP) and procalcitonin(PCT) in the diagnosis of neonatal sepsis.Methods A total of 70 neonates diag-nosed with neonatal sepsis(sepsis group),35 cases of non-infectious diseases(non-infected group),and 40 healthy newborns(healthy control group) were enrolled in the Department of Pediatrics,Fuzhou First Hospital Affiliated to Fujian Medical University from July 2015 to June 2016. Serum CD64 was detected by flow cytometry.Serum CRP and PCT were detected by automatic biochemical analyzer,and the results were com-pared and analyzed.Results The levels of serum CD64,CRP and PCT in sepsis group were significantly higher than those in non-infected group and healthy controls(P <0.05).The sensitivity and specificity of CD64 combined with CRP and PCT in the detection of neonatal sepsis were 97.14% and 96.00%,and the sensitivity and specificity in the combined detection were higher than those in three indicators alone.Conclusion CD64 combined with CRP and PCT in the detection of neonatal sepsis can improve the specificity,and provide the basis for early diagnosis.

ABSTRACT

Objective To investigate the value of carotid and lower limbs arteries atherosclerosis in prediction of intracranial atherosclerosis combined with type 2 diabetes (T2DM). Methods Seventy-four patients with T2DM received the carotid artery , lower limbs arterial color Doppler ultrasound and cranial MRA examination. The data was analysised by Pearson correlation and Binary Logistic methods. Results With the increasement of degree of peri-arterial atherosclerosis , the intracranial arteriosclerosis was in a trend of increase. The correlation coefficients, OR values and AUC of LLAS and CAS + LLAS for intracranial atherosclerosis were 0.28 (P < 0.05) and 0.33 (P < 0.05), 0.14 (P < 0.05) and 9.28 (P < 0.05), 70.30% (P < 0.05) and 70.60% (P < 0.05), respectively. The cut-off point of LLAS and CAS + LLAS was lever 2. Conclusion The LLAS and CAS + LLAS with T2DM are independent risk factors for intracranial atherosclerosis , owning certain forecast values.

ABSTRACT

AIM: To study the effect of cholecystokinin octapeptide(CCK-8) on lipopolysaccharide (LPS)-stimulated pulmonary interstitial macrophage(IM) in vitro. METHODS: Pulmonary IM were isolated and cultured in the presence of LPS, CCK-8, proglumide(the antagonist of CCK receptors) and vehicle alone or together. The expression of mCD14 protein was assayed by flow cytometry, and sCD14 in the supernatant was analyzed semi-quantitatively by Western blot, and TNF-? in the supernatant was detected with ELISA. RESULTS: CCK-8, at concentrations from 10 -7 mol/L to 10 -6 mol/L inhibited significantly the expression of mCD14, the release of sCD14 and TNF-? to the supernatant up-regulated by LPS(1 mg/L). The effect of CCK-8 was inhibited by proglumide. CONCLUSION: CCK-8 modulated negatively several functions of LPS-stimulated pulmonary IM through CCK receptors, which may be one of the mechanisms for CCK-8 to alleviate the inflammation in lung tissues during endotoxemia.
