Changes and clinical significance of autophagy-related proteins Beclin-1 and cytochromes C in patients with hand, foot and mouth disease / 中华微生物学和免疫学杂志

Objective:To investigate the expression and clinical significance of Beclin-1 and cytochromes C (CytC) in patients with hand, foot and mouth disease (HFMD).Methods:Sixty children with HFMD were classified into two groups of severe group and common group with 30 cases in each group. Another thirty children who underwent circumcision and had no underlying disease were selected as control group. Serum Beclin-1, CytC and S100B levels were detected before and after treatment. The levels of Beclin-1 and CytC in cerebrospinal fluid (CSF) of children with severe HFMD were detected before and after treatment. Receiver operating characteristic (ROC) curve was used to evaluate the prediction efficiency of Beclin-1 and CytC for the severity of HFMD.Results:Serum Beclin-1 and CytC levels in the severe group were higher than those in the other two groups ( P<0.01), and the common group showed significantly increased serum Beclin-1 and CytC levels as compared with the control group ( P<0.01). After treatment, the serum Beclin-1 and CytC levels decreased in both severe and common groups ( P<0.05). Compared with the common group, the severe group had remarkable increases in the levels of Beclin-1 and CytC in CSF ( P<0.01), which decreased significantly after treatment ( P<0.01). Serum Beclin-1 and CytC levels were positively correlated with the level of S100B protein. In the prediction of severe HFMD, serum CytC had the highest Youden value of 0.533 at the cut-off value of 38.785 ng/ml with a sensitivity of 56.67% and a specificity of 96.67%; serum Beclin-1 had the highest Youden value of 0.467 at the cut-off value of 6.560 ng/ml with a sensitivity of 46.67% and a specificity of 100.00%. Combined measurements of these two parameters had the highest predictive value for severe HFMD with a sensitivity of 76.67% and a specificity of 96.67%. Conclusions:Serum Beclin-1 and CytC levels were conducive to predict the severity and treatment outcomes of HFMD. Combined measurements of these two parameters had a higher predictive value for severe HFMD.

Objective:To analyze the risk factors of modified midline catheter-related thrombosis and propose countermeasures.Methods:Retrospective analysis was used to divide patients admitted to the neurology department of Nanjing Drum Tower Hospital from February 2018 to July 2020 into thrombotic group (9 cases) and nonthrombotic group (117 cases). Univariate analysis and binary Logistic regression were used to analyze the risk factors for catheter-related thrombosis.Results:The incidence of thrombosis was 7.14% (9/126) in patients with modified midline catheters. Univariate analysis showed that the occurrence of catheter-related thrombosis in patients was related to the primary type ( χ2 value was 6.331, P<0.05) and catheter pretreatment ( χ2 value was 4.016, P<0.05). Multivariate analysis showed that there was no significant difference between the primary disease type and the catheter pretreatment method ( P>0.05). Conclusions:The incidence of thrombus in patients with encephalitis and pretreated catheter with normal saline is high, preventive care should be taken before the occurrence of thrombus, and thrombolytic therapy should be taken as soon as possible after the occurrence of thrombus.

Correlation of serum alanine aminotransferase, aspartate aminotransferase, gamma-glutamyl transpeptidase, and alkaline phosphatase with blood pressure in patients with nonalcoholic fatty liver disease in coastal regions of Shandong Province in China / 临床肝胆病杂志

Objective To investigate whether there was a correlation between serum liver enzyme levels and blood pressure in the Chinese Han population with nonalcoholic fatty liver disease (NAFLD) in Shandong coastal regions in China. Methods A total of 269 NAFLD patients who lived in Shandong coastal regions and attended or underwent physical examination in Qingdao Municipal Hospital from December 2019 to June 2020 were enrolled, among whom 105 had hypertension and 164 did not have hypertension. Morning blood pressure was measured to calculate mean arterial pressure (MAP), and laboratory tests were performed to measure the serum levels of liver enzymes [alanine aminotransferase (ALT), aspartate aminotransferase (AST), gamma-glutamyl transpeptidase (GGT), and alkaline phosphatase (ALP)] and fasting blood glucose (FBG). The independent samples t -test was used for comparison of normally distributed continuous data between two groups, and the Mann-Whitney U test was used for comparison of non-normally distributed continuous data between two groups; the chi-square test was used for comparison of categorical data between two groups. A Pearson correlation analysis was used to investigate the correlation of four liver enzymes with the indices including MAP, and a binary logistic regression model was used to analyze the impact of serum liver enzymes on hypertension. Results Compared with the non-hypertension group, the hypertension group had significantly higher body mass index (BMI), MAP, and GGT (all P < 0.05). For all NAFLD patients and the NAFLD patients without hypertension, male patients had significantly higher BMI, MAP, ALT, AST, and GGT than female patients (all P < 0.05), and for the NAFLD patients with hypertension, male patients had a significantly higher level of GGT than female patients ( P < 0.05). There was a significant difference in the distribution of GGT between the hypertension group and the non-hypertension group, and compared with the non-hypertension group, the hypertension group had a significantly higher proportion of patients with GGT exceeding the normal range ( χ 2 =4.781, P =0.029). Serum GGT level was correlated with MAP within the normal range (70-105 mm Hg) ( r =0.178, P =0.011), while there was no significant correlation when MAP exceeded the normal range ( P =0.415). After adjustment for age and sex, the binary logistic regression model showed that AST level was positively associated with hypertension in the population with NAFLD (odds ratio [ OR ]=1.011, 95% confidence interval [ CI ]: 1.000-1.022, P =0.040), and after further adjustment for BMI and FBG, the results showed that AST level was still positively associated with hypertension ( OR =1.011, 95% CI : 1.000-1.022, P =0.044). Conclusion In Chinese Han population with NAFLD in Shandong coastal regions, higher levels of AST may predict an increased risk of hypertension.

Advances of Angiopoietin-Tie axis in vascular and lymphatic system-related diseases / 生物工程学报

Endothelial cells that form the inner layers of both blood and lymphatic vessels are important components of the vascular system and are involved in the pathogenesis of vascular and lymphatic diseases. Angiopoietin (Ang)-Tie axis in endothelial cells is the second endothelium-specific ligand-receptor signaling system necessary for embryonic cardiovascular and lymphatic development in addition to the vascular endothelial growth factor receptor pathway. The Ang-Tie axis also maintains vascular homeostasis by regulating postnatal angiogenesis, vessel remodeling, vascular permeability, and inflammation. Therefore, the dysfunction of this system leads to many vascular and lymphatic diseases. In light of the recent advances on the role of the Ang-Tie axis in vascular and lymphatic system-related diseases, this review summarizes the functions of the Ang-Tie axis in inflammation-induced vascular permeability, vascular remodeling, ocular angiogenesis, shear stress response, atherosclerosis, tumor angiogenesis, and metastasis. Moreover, this review summarizes the relevant therapeutic antibodies, recombinant proteins, and small molecular drugs associated with the Ang-Tie axis.

KCNJ11 rs5210 polymorphism and genetic susceptibility to nonalcoholic fatty liver disease and coronary artery disease / 临床肝胆病杂志

ObjectiveTo investigate the association of KCNJ11 rs5210 single nucleotide polymorphism with nonalcoholic fatty liver disease (NAFLD) and coronary artery disease (CAD) in the Chinese Han population in Qingdao, China. MethodsA total of 246 patients with NAFLD who attended Qingdao Municipal Hospital from December 2018 to September 2019 were enrolled as NAFLD group, 201 patients with CAD were enrolled as CAD group, and 116 patients with NAFLD and CAD were enrolled as NAFLD+CAD group; 342 healthy individuals were enrolled as control group. Fasting venous blood samples were collected for biochemical analysis. Whole blood genomic DNA was extracted, and PCR was used to determine KCNJ11 rs5210 genotype. The chi-square test was used to analyze whether the distribution of KCNJ11 rs5210 gene frequencies met the Hardy-Weinberg equilibrium, in order to determine whether the tested samples could represent the population. The chi-square test was used to analyze the differences in sex and genotype/allele frequency between groups. A one-way analysis of variance was used for comparison of normally distributed continuous data between multiple groups, and the least significant difference t-test was used for further comparison between two groups; the Kruskal-Wallis H test was used for comparison of non-normally distributed continuous data between multiple groups, and the Bonferroni method was used for further comparison between two groups. The unconditional logistic regression model was used to calculate odds ratio (OR) and 95% confidence interval. ResultsThree genotypes (AA, GA, and GG) of KCNJ11 rs5210 were found by gene sequencing. There were no significant differences in rs5210 allele frequency and genotype distribution between the control group, the NAFLD group, the CAD group, and the NAFLD+CAD group (all P＞0.05), and there were still no significant differences after adjustment for sex, age, and body mass index (BMI) (all P＞0.05). For all subjects, the subjects with AA genotype had a higher level of alkaline phosphatase than those with GA genotype (P=0.048); in the NAFLD group, the patients with GA genotype had significantly higher BMI and total bilirubin than those with AA genotype (P=0.042 and 0.002). The unconditional logistic regression analysis showed that elevated BMI was associated with the risk of NAFLD (OR=1.35, P＜0.01), while decreased high-density lipoprotein (HDL) might indicate an increase in the risk of NAFLD (OR=0.33, P＜0.01); elevated fasting plasma glucose and decreased HDL might indicate an increase in the risk of CAD (OR=1.51 and 0.11, both P＜0.01) and NAFLD with CAD (OR=1.46 and 0.06, both P＜0.01). ConclusionThere is no significant association between KCNJ11 rs5210 polymorphism and the risk of NAFLD and CAD in the Chinese Han population in Qingdao.

The size distribution of ethanol liposomes and propylene glycol liposomes was studied different volume ratio of alcohol to water, stirring speed and mode of membrane passmg. An orthogonal design was adopted to obtain the optimal preparation technology based on the influences. Preliminary stability of the three different solvent medium liposomes was evaluated respectively on 0,1st,15th and 30th day using the changes of morphology and the mean particle size as the indicators. Results:The results of orthogonal test showed that the best preparation method for common liposomes was as follows:the hydration time was 60 min,the water bath temperature was 50℃ and the rotation speed was 200 r·min-1. The best preparation method for ethanol liposomes and propylene glycol liposomes was as follows:the volume ratio of alcohol to water was 1:2,the stirring speed was 1 000 r·min-1and the mode of membrane passing was 0.45 μm at first and then changed to 0.22 μm. Under the optimum preparation conditions, the three liposomes were closed monolayer or multilayer cystic spherosomes. The average diameter of common liposomes, ethanol liposomes and propylene glycol liposome was (1 016.2 ± 135.6),(578.7 ± 89.2) and (351.4 ± 53.8) nm, respectively. All the three liposomes were unstable during the one-month observation period. After the 15-day storage, obvious delamination appeared.Conclusion:Three different solvent medium liposomes prepared with the best process are in micro-scale or nano-scale. They are in poor stability, which should be freshly prepared before use.
