		                        			OBJECTIVES:
		                        			To study the value of heparin-binding protein (HBP) in the diagnosis of severe infection in children.
		                        		
		                        			METHODS:
		                        			This study was a prospective observational study. The medical data of children who were admitted to the pediatric intensive care unit due to infection from January 2019 to January 2020 were collected. According to the diagnostic criteria for severe sepsis and sepsis, the children were divided into a severe sepsis group with 49 children, a sepsis group with 82 children, and a non-severe infection group with 33 children. The three groups were compared in terms of related biomarkers such as plasma HBP, serum C-reactive protein, serum procalcitonin, and platelet count. The receiver operating characteristic (ROC) curve was plotted to investigate the value of plasma HBP level in the diagnosis of severe infection (including severe sepsis and sepsis).
		                        		
		                        			RESULTS:
		                        			The severe sepsis and sepsis groups had a significantly higher plasma HBP level on admission than the non-severe infection group (P<0.05). Compared with the sepsis and non-severe groups, the severe sepsis group had significantly higher serum levels of C-reactive protein and procalcitonin and a significantly lower platelet count (P<0.05). Plasma HBP level had an area under the ROC curve of 0.590 in determining severe infection, with a sensitivity of 38.0% and a specificity of 82.4% (P<0.05).
		                        		
		                        			CONCLUSIONS
		                        			There is an increase in plasma HBP level in children with severe infection, and plasma HBP level has a lower sensitivity but a higher specificity in the diagnosis of severe infection and can thus be used as one of the markers for the judgment of severe infection in children.

		                        			OBJECTIVE:
		                        			To screen potential plasma protein biomarkers for the progression of cervical precancerous lesions into cervical carcinoma and analyze their functions.
		                        		
		                        			METHODS:
		                        			Plasma samples obtained from healthy control subjects, patients with low-grade squamous intraepithelial lesion (LSIL), high-grade squamous intraepithelial lesion (HSIL), cervical cancer (CC), and patients with CC after treatment were enriched for low-abundance proteins for liquid chromatography-tandem mass spectrometry (LC-MS/MS) analysis. The MS data of the samples were analyzed using Discoverer 2.2 software, and the differential proteins (peptide coverage ≥20%, unique peptides≥2) were screened by comparison of LSIL, HSIL and CC groups against the control group followed by verification using target proteomics technology. Protein function enrichment and coexpression analyses were carried out to explore the role of the differentially expressed proteins as potential biomarkers and their pathological mechanisms.
		                        		
		                        			RESULTS:
		                        			Compared with the control group, both LSIL group and HSIL group showed 9 differential proteins; 5 differentially expressed proteins were identified in CC group. The proteins ORM2 and HPR showed obvious differential expressions in LSIL and HSIL groups compared with the control group, and could serve as potential biomarkers for the progression of cervical carcinoma. The expression of F9 increased consistently with the lesion progression from LSIL to HSIL and CC, suggesting its value as a potential biomarker for the progression of cervical cancer. CFI and AFM protein levels were obviously decreased in treated patients with CC compared with the patients before treatment, indicating their predictive value for the therapeutic efficacy. Protein function enrichment analysis showed that all these differentially expressed proteins were associated with the complement system and the coagulation cascades pathway.
		                        		
		                        			CONCLUSIONS
		                        			We identified 5 new protein biomarkers (F9, CFI, AFM, HPR, and ORM2) for cervical precancerous lesions and for prognostic evaluation of CC, and combined detection of these biomarkers may help in the evaluation of the development and progression of CC and also in improving the diagnostic sensitivity and specificity of cervical lesions.

		                        			OBJECTIVE:
		                        			To explore the predictive value of heparin-binding protein (HBP) combined with sequential organ failure assessment (SOFA) score in patients with septic shock.
		                        		
		                        			METHODS:
		                        			Seventy-eight patients with sepsis admitted to intensive care unit (ICU) of Henan Provincial People's Hospital from December 2016 to May 2017 were enrolled. Thirty healthy persons were enrolled as controls. The patient's gender, age, length of ICU stay, and blood culture results, white blood cell count (WBC), C-reactive protein (CRP), procalcitonin (PCT), blood lactate (Lac), HBP, SOFA score, acute physiology and chronic health evaluation II (APACHE II) score, organ failure and vasoactive agents usage within 24 hours of admission were recorded. The differences in the above indicators between the groups were compared, and the receiver operating characteristic (ROC) curve was drawn to evaluate the predictive value of HBP, SOFA score and their combination in patients with septic shock.
		                        		
		                        			RESULTS:
		                        			All patients were enrolled in the final analysis, including 64 with sepsis and 14 with septic shock. Compared with the sepsis group, the proportion of patients with septic shock who were positive for blood culture, organ failure, and vasoactive agents was higher [57.1% (8/14) vs. 7.8% (5/64), 100.0% (14/14) vs. 65.6% (42/64), 100.0% (14/14) vs. 18.8% (12/64), all P < 0.01], SOFA and APACHE II scores were also higher (SOFA: 8.93±4.16 vs. 5.89±2.68, APACHE II: 22.29±4.89 vs. 15.28±5.14, both P < 0.01); however, there was no significant difference in gender, age or length of ICU stay between the two groups. Compared with the healthy control group, HBP, PCT, CRP and Lac levels were significantly increased in the sepsis group and the septic shock group. HBP in the septic shock group was significantly higher than that in the sepsis group (μg/L: 120.33±43.49 vs. 68.95±54.15, P < 0.05), but there was no significant difference in PCT, CRP or Lac between septic shock group and sepsis group [PCT (μg/L): 1.42 (0.47, 46.00) vs. 0.71 (0.19, 4.50), CRP (mg/L): 102.90±78.12 vs. 102.07±72.15, Lac (mmol/L): 1.81 (1.14, 3.65) vs. 1.59 (1.17, 2.24), all P > 0.05]. It was shown by ROC curve analysis that the area under the ROC curve (AUC) of SOFA score for predicting septic shock was 0.715 [95% confidence interval (95%CI) = 0.540-0.890, P = 0.012], and when the optimal cut-off value was 7.5, the sensitivity was 64.3%, the specificity was 76.6%. The AUC of HBP was 0.814 (95%CI = 0.714-0.913, P < 0.001), and when the optimal cut-off value was 89.43 μg/L, the sensitivity was 78.6%, the specificity was 76.6%; when the two were combined, the AUC was 0.829 (95%CI = 0.724-0.935, P < 0.001), the sensitivity was 92.9%, and the specificity was 61.9%.
		                        		
		                        			CONCLUSIONS
		                        			HBP can be used as a biological indicator for predicting septic shock, and the accuracy of predicting septic shock can be improved with the combination of SOFA score.

		                        			To investigate the role of autophagy inhibitor chloroquine (CQ) in acute ethanol-induced liver injury and its mechenism.
		                        		
		                        			METHODS:
		                        			Twenty-one C57BL/6 male mice were randomly divided into three groups:control group, ethanol group, CQ + ethanol group (=7). Mice in ethanol group were administered 33% (v/v) ethanol at a dose of 4.5 g/kg body weight. Ethanol-induced liver steatosis in each group was detected by hematoxylin and eosin staining. Hepatic lipid accumulation was detected by staining with Oil red O. Hepatic tissue triglyceride (TG) levels, serum aspartate aminotransferase(AST) and alanine aminotransferase(ALT) were determined by biochemical assays. Protein expression of microtubule-associated protein 1 light chain 3(LC3) and nuclear factorκB p65(NF-κB p65) were measured by Western blot and immunofluorescence. Pro-inflammatory factors tumor necrosis factor-α(TNF-α)、interleukin 6(IL-6) were detected by ELISA.
		                        		
		                        			RESULTS:
		                        			Compared with control group, ethanol induced liver injury proved by accumulation of hepatic lipids, TG levels, AST and ALT activities were significantly increased by ethanol, protein expression of LC3-Ⅱ was also markedly increased by ethanol. Compared with ethanol group, addition of CQ increased furtherthe level of LC3-Ⅱexpression, and TG amount, serum AST and ALT activities, and the expression of NF-κB p65, TNF-αand IL-6.
		                        		
		                        			CONCLUSIONS
		                        			Acute ethanol-intake could induce liver steatosis and inflammation, and autophagy inhibitor CQ exacerbatedethanol-induced liver injury, suggested that autophagy might be protective effect in acute ethanol-induced liver disease.

		                        			BACKGROUND: Carotid artery intima medial thickness (IMT), brachial-ankle pulse wave velocity (baPWV), and ankle-brachial index (ABI) are commonly used surrogate markers of subclinical atherosclerosis in patients with type 2 diabetes mellitus (T2DM). The cardio-ankle vascular index (CAVI) is a complement to the baPWV, which is affected by blood pressure. However, it is unclear which marker is the most sensitive predictor of atherosclerotic cardiovascular disease (ASCVD). METHODS: This was a retrospective non-interventional study that enrolled 219 patients with T2DM. The correlations among IMT, ABI, and CAVI as well as the relationship of these tests to the 10-year ASCVD risk were also analyzed. RESULTS: Among the 219 patients, 39 (17.8%) had ASCVD. In the non-ASCVD group, CAVI correlated significantly with IMT after adjusting for confounding variables, but ABI was not associated with CAVI or IMT. The analyses after dividing the non-ASCVD group into three subgroups according to the CAVI score ( < 8, ≥8 and < 9, and ≥9) demonstrated the significant increase in the mean IMT, 10-year ASCVD risk and number of metabolic syndrome risk factors, and decrease in the mean ABI in the high-CAVI group. A high CAVI was an independent risk factor in the non-ASCVD group for both a high 10-year ASCVD risk (≥7.5%; odds ratio [OR], 2.42; P < 0.001) and atherosclerosis (mean IMT ≥1 mm; OR, 1.53; P=0.007). CONCLUSION: In Korean patients with T2DM without ASCVD, CAVI was the most sensitive of several surrogate markers for the detection of subclinical atherosclerosis.

		                        			Catalpol, a major bioactive component from Rehmannia glutinosa, which has been used to treat diabetes. The present study was designed to elucidate the anti-diabetic effect and mechanism of action for catalpol in db/db mice. The db/db mice were randomly divided into six groups (10/group) according to their blood glucose levels: db/db control, metformin (positive control), and four dose levels of catalpol treatment (25, 50, 100, and 200 mg·kg), and 10 db/m mice were used as the normal control. All the groups were administered orally for 8 weeks. The levels of fasting blood glucose (FBG), random blood glucose (RBG), glucose tolerance, insulin tolerance, and glycated serum protein (GSP) and the globe gene expression in liver tissues were analyzed. Our results showed that catalpol treatment obviously reduced water intake and food intake in a dose-dependent manner. Catalpol treatment also remarkably reduce fasting blood glucose (FBG) and random blood glucose (RBG) in a dose-dependent manner. The RBG-lowering effect of catalpol was better than that of metformin. Furthermore, catalpol significantly improved glucose tolerance and insulin tolerance via increasing insulin sensitivity. Catalpol treatment significantly decreased GSP level. The comparisons of gene expression in liver tissues among normal control mice, db/db mice and catalpol treated mice (200 and 100 mg·kg) indicated that there were significant increases in the expressions of 287 genes, whichwere mainly involved in lipid metabolism, response to stress, energy metabolism, and cellular processes, and significant decreases in the expressions of 520 genes, which were mainly involved in cell growth, death, immune system, and response to stress. Four genes expressed differentially were linked to glucose metabolism or insulin signaling pathways, including Irs1 (insulin receptor substrate 1), Idh2 (isocitrate dehydrogenase 2 (NADP), mitochondrial), G6pd2 (glucose-6-phosphate dehydrogenase 2), and SOCS3 (suppressor of cytokine signaling 3). In conclusion, catalpol ecerted significant hypoglycemic effect and remarkable therapeutic effect in db/db mice via modulating various gene expressions.

OBJECTIVETo observe the effects of recombinant fusion protein interleukin (IL)-18 on the expression of immune-inflammatory factors in the mice infected with Staphylococcus aureus (SA), and to investigate the mechanism of action of IL-18 in defense of SA infection in vivo.
METHODSA total of 40 specific pathogen-free female BLAB/c mice were randomly divided into four groups: control, SA infection, immunized, and intervention. A mouse model of SA infection was established by nasal inoculation with SA liquid. The immunized group and the intervention group were intranasally given IL-18 before SA modeling, and then the SA infection group and the intervention group received the nasal inoculation with SA liquid; the control group was treated with phosphate buffered saline instead. The levels of IL-4, interferon (IFN)-γ, tumor necrosis factor (TNF), granulocyte colony-stimulating factor (G-CSF), IgM in the serum and bronchoalveolar lavage fluid (BALF) of mice were measured by enzyme-linked immunosorbent assay. The expression of macrophage inflammatory protein (MIP)-1α mRNA and MIP-2β mRNA in the lung tissue of mice were determined by real-time fluorescent quantitative PCR.
RESULTSCompared with the control group, the SA infection group and the immunized group had significantly higher levels of IL-4, G-CSF, and IgM in the serum and BALF and expression of MIP-1α mRNA and MIP-2β mRNA in the lung tissue (P<0.05); the SA infection group had a significantly lower level of IFN-γ and a significantly higher level of TNF in the serum and BALF (P<0.05); the immunized group had a significantly higher level of IFN-γ in the serum and BALF (P<0.05). Compared with the SA infection group, the intervention group had significantly higher levels of IL-4, IFN-γ, G-CSF, and IgM in the serum and BALF and expression of MIP-1α mRNA in the lung tissue. In contrast, the intervention group showed a significantly lower level of TNF in the serum and BALF and expression of MIP-2β mRNA in the lung tissue (P<0.05). All the above indicators in the intervention group were significantly higher than those in the control group (P<0.05), except the serum level of IFN-γ.
CONCLUSIONSIn the mice infected with SA, the recombinant fusion protein IL-18 by mucosal immunity can affect inflammatory factors in the serum and BALF and the expression of MIP-1α mRNA and MIP-2β mRNA in the lung tissue to promote the anti-infective immune response and enhance the ability to clear pathogens.

		                        			Malnutrition is commonly seen in children with chronic liver diseases, and there are interactions between them. Chronic liver diseases can cause malnutrition and this can affect the prognosis of children with chronic liver diseases. Due to the complexity of nutritional assessment in children with chronic liver diseases, there are still no unified standards for the diagnosis of malnutrition. Early identification of malnutrition and related intervention helps to improve the prognosis of children with chronic liver diseases. This article reviews the features of nutrition in children with chronic liver diseases and related nutritional assessment methods.

OBJECTIVETo explore the predictive value of combination detection of Pgp1 expression in cancer tissue and serum CEA level for the prognosis of colorectal cancer (CRC) patients.
METHODSClinicopathological data, complete 5-year follow-up data and CRC tissue samples of 153 CRC patients with stage I( to II( tumor undergoing radical operation in our department from January 2004 to August 2006 were retrospectively collected. Immunohistochemical staining was used to detect the expression level of Pgp1. The combined evaluation of staining intensity and positive cell percentage was performed to determine the expression level of Pgp1. Pgp1 staining (-) and (+) was defined as low expression; and staining (++) and (+++) as high expression. Electrochemiluminescence immunoassay was used to detect the level of serum CEA. CEA > 5 μg/L was defined as positive. χand Fisher's exact test were performed to analyze the association of Pgp1 expression with CEA level and clinicopathological variables. Moreover, Kaplan-Meier method was used to analyze the survival. Univariate and multivariate Cox proportional hazard regression models were used to evaluate the roles of Pgp1 expression combined with serum CEA level in prognosis prediction.
RESULTSOf 153 patients, 105 were males and 48 females with mean age of 59 (27 to 90) years; 41 cases were rectal cancer, and 112 cases colon cancer; 23 patients were TNM stage I( tumor, and 130 patients stage II( tumor; median follow-up time was 64 months; 30 cases were dead. Positive rate of Pgp1 expression in colorectal cancer tissues was 66.0%(101/153). The expression of Pgp1 was associated with gender, tumor location, and survival during the follow-up (all P<0.05). The preoperative positive rate of serum CEA was 28.1% (43/153). The preoperative serum CEA level was associated with tumor recurrence and survival (all P<0.05). Kaplan-Meier analysis showed the overall 5-year survival rate was 81.7%. The 5-year survival rate of patients with high expression of Pgp1 was 88.1%, which was significantly higher than 69.2% of those with low expression of Pgp1(P=0.003). The 5-year survival rate of patients with preoperative positive serum CEA was 72.1%, which was significantly lower than 86.1% of those with preoperative negative serum CEA(P=0.023). Furthermore, the 5-year survival rate of patients with negative Pgp1 plus positive CEA was 66.7%, which was significantly lower than 91.0% of those with positive Pgp1 plus negative CEA(P=0.002). Univariate analysis showed that gender, Pgp1 expression level, preoperative serum CEA level, and Pgp1 combined with CEA were significantly associated with the prognosis of patients(all P<0.05). Multivariate analysis showed that Pgp1 expression was an independent prognostic factor of CRC [HR(95%CI:1.261 to 64.224), P=0.028].
CONCLUSIONSLow expression of Pgp1 in cancer tissue indicates poor prognosis in patients with stage I( and II( tumor. Combination detection of Pgp1 expression and serum CEA can be applied to predict the prognosis of patients with stage I( and II( colorectal cancer.
