Sepsis is a frequent condition with high mortality,and its early diagnosis in the pediatrics department is one of the keys to improve survival. C-reactive protein and procalcitonin have been used as bio-markers in the diagnosis of sepsis,but they have limited susceptibility and specificity,and can be elevated in non inflammatory condition. Presepsin is the free fragment of a glycoprotein expressed on monocytes/macro-phages. Preliminiary reports suggest that levels of presepsin are significantly higher in septic patients com-pared to healthy individuals, and presepsin is useful for evaluating the severity of sepsis.

OBJECTIVE: To investigate the correlation between tongue body MRI measurements and the lingual region obstruction in patients with obstructive sleep apnea hypopnea syndrome (obstructive sleep apnea hypopnea syndrome, OSAHS), and the relationship of two diagnosis methods in positioning obstructive level, in order to improve the preoperative diagnostic accuracy of obstructive level in OSAHS patients . METHOD: Fifty-nine patients with OSAHS definited by the AG200 sleep apnea monitoring and obstruction plane positioning system was included. They all underwent tongue MRI scan, after three-dimensional reconstruction, the tongue body length to diameter, relative thickness, basal diameter, wide around central about wide diameter and tongue body volume were measured. The lower blocking (mainly composed of lingual region) constituent ratio P established by AG200 was correlated with tongue parameters measured by MRI. At the same time, To analysis of differences of P in patients with different degree of OSAHS. RESULT: Among these patients with OSAHS in different degree, the coefficient correlation between tongue parameters(tongue length, relative thickness, basal diameter, wide middle diameter, tongue body volume) and lower blocking constitute ratio P werer LP = 0.051,rHP = 0.069, r1 = 0.215, r2 = 0.147, rVP = 0.259, respectively. lower obstruction of form than the differences had statistical significance. The measured tongue parameters and value P(the lower blocking constituent ratio) were negatively correlated, which demonstrated that exclusing of the larynx and hypopharynx airway obstruction, the lower airway obstruction detected by AG200 was related with tongue parameters measured by MRI, and was strongestly related with the tongue body volume. CONCLUSION The volume of tongue and AG had correlation in judgement of lower blocking. In OSAHS patients the lower blocking constituent ratio varies between the defferent severity groups of the disease, the combina tion of the two method can be used to predict the obstructive plane in OSAHS patients with upper airway obstruction, and provide the basis for the individual treatment of patients with OSAHS.

AIM: To find new gene function associate with active lupus nephritis (LN) through study on the difference in gene expression of peripheral blood mononuclear cells between LN patients and healthy controls by gene chip. METHODS: The CSC-GE-80 chip containing 8 000 spots of cDNAs were used to investigate the difference of the expression. Both the total RNA from peripheral blood mononuclear cells of active LN patients and healthy donors were reversely transcribed to cDNA with the incorporation of fluorescent( cy3 and cy5) labeled dCTP to prepare the hybridization probes. After hybridization, the gene chip was scanned for the fluorescent intensity. The differentially expressed genes were screened. We repeated that in three groups of LN patients and healthy controls, respectively, and only the genes that have differential expression in all three chips were considered associated with LN. RESULTS: 75 genes were identified to be differently expressed in all three groups of LN patients as compared with healthy controls, including 42 up-regulated genes and 33 down-regulated ones. CONCLUSION: The present study represents a global view of gene expression of LN and provides important clues for further study of LN related genes. And it also suggests defensin ? 1, S100A8, S100A9 may be involved in the pathogenesis of LN.

Objective:To compare the therapeutic effects by different longitude margins of the gross tumor volume (GTV) based on elec-tive nodal irradiation (ENI) and to investigate the optimization of clinical tumor volume (CTV) in the radical chemoradiotherapy of esophageal squamous cell carcinoma (ESCC). Methods:ESCC patients treated with chemoradiotherapy for the first time in the First Af-filiated Hospital of Xiamen University from May 2009 to November 2012 were retrospectively studied. All patients were treated with ENI for radical radiotherapy, and the patients were divided into two groups:CTV1 group (with longitudinal external expansion length of less than 3 cm) and CTV2 group (with longitudinal external expansion length of more than 3 cm). The survival time and occurrence of side effects in patients were compared. Results:Among the 142 cases of patients, 82 and 61 cases were classified under CTV1 and CTV2, respectively. No significant difference in the overall survival (OS) and local recurrence-free survival (LRFS) rates was observed af-ter 1, 3, and 5 years of treatment between the two groups. The occurrence of side effects, such as bone marrow suppression, radiation pneumonitis, radiation esophagitis, and esophageal fistula, was less than 5%in both groups, and the data show that the side effect oc-currence in CTV1 was significantly lower. Conclusion:In the radical chemoradiotherapy of esophageal cancer using ENI, the OS rate of patients with a delineated CTV according to a 3 cm GTV longitudinal external expansion length is not lower than that of patients with a delineated CTV according to a GTV longitudinal external expansion length of more than 3 cm. The results provide a reference for the optimization of CTV in the radical chemoradiotherapy of ESCC.

Objective:To compare the effects of different doses of atorvastatin on blood lipid and endothelial function in patients with hypertension and carotid plaque.Methods:Ninety-two patients with hypertension and carotid plaque who received treatment from June 2019 to June 2020 were included in this study. They were assigned to receive treatment with either atorvastatin 20 mg (control group, n = 46) or atorvastatin 40 mg (study group, n = 46) for 3 months. Blood lipid level and endothelial function were compared between the two groups. Results:There were no significant differences in sex, age, course of disease, body mass index (BMI) and carotid plaque grading between the two groups (all P > 0.05). Before treatment, there were no significant differences in serum levels of total cholesterol (TC), triglyceride (TG), high density lipoprotein cholesterol (HDL-C) and low density lipoprotein cholesterol (LDL-C) between two groups (all P > 0.05). After treatment, serum levels of TC, TG and LDL-C in each group were significantly decreased compared with before treatment [study group: TC: (5.8 ± 2.3) mmol/L vs. (3.5 ± 1.3) mmol/L, t = 5.904; TG: (2.5 ± 0.8) mmol/L vs. (1.2 ± 0.5) mmol/L, t = 9.346; LDL-C: (5.0 ± 0.4) mmol/L vs. (3.3 ± 0.4) mmol/L, t = 20.382; control group: TC: (5.9 ± 1.8) mmol/L vs. (4.5 ± 1.5) mmol/L, t = 4.052; TG: (2.6 ± 0.3) mmol/L vs. (1.8 ± 0.7) mmol/L, t = 7.125; LDL-C: (4.9 ± 0.5) mmol/L vs. (4.2 ± 0.5) mmol/L, t = 6.714, all P < 0.01). After treatment, serum level of HDL-C in each group was significantly increased compared with before treatment [study group: (0.8 ± 0.5) mmol/L vs. (1.5 ± 0.3) mmol/L, t = 8.142; control group: (0.8 ± 0.4) mmol/L vs. (1.3 ± 0.2) mmol/ L, t = 7.583, both P < 0.01]. After treatment, serum levels of TC, TG and LDL-C in the study group were significantly lower than those in the control group ( tTC = 3.417, tTG = 4.731, tLDL-C = 9.533, all P < 0.01). After treatment, serum level of HDL-C in the study group was significantly higher than that in the control group ( tHDL-C = 3.762, P < 0.01). Before treatment, there were no significant differences in endothelium-dependent (flow mediated dilation, FMD) and endothelium-independent diastolic function (nitroglycerin- mediated dilatation, NMD) between the two groups (both P > 0.05). After treatment, FMD in each group was significantly enhanced compared with before treatment [study group: (7.5 ± 1.8) % vs. (10.9 ± 2.5) %, t = 7.486; control group: (7.7 ± 1.5) % vs. (8.9 ± 2.2) %, t = 3.057; both P < 0.05]. After treatment, FMD in the study group was significantly higher than that in the control group ( t = 4.073, P < 0.01). There was no significant difference in NMD between before and after treatment in the control group. After treatment, NMD in the study group was significantly increased compared with before treatment [(12.5 ± 2.3) % vs. (13.6 ± 2.5) %, t = 2.196, P = 0.031]. Conclusion:Atorvastatin 40 mg once a day can effectively regulate blood lipid level and improve endothelial function in patients with hypertension and carotid plaque, which exhibits superior effects to atorvastatin 20 mg once a day.
