Objective To investigate the correlation of triacylglycerol glucose(TyG)index,monocyte to high-density lipoprotein cholesterol ratio(MHR)with coronary artery disease and myocardial ischemia degree in coronary heart disease(CHD),and to analyze the two Predictive value of coronary artery disease and myocardial ischemia degree.Methods CHD patients from the 920th Hospital of the Chinese People's Liberation Army Joint Logistics Support Force from January 2019 to January 2022 were selected as the study group(n = 150),and healthy physical examination subjects from the same period were selected as the control group(n = 75).The TyG index and MHR of the two groups were compared and analyzed.The extent of coronary artery disease was evaluated based on the Gensini score,and the TyG index and MHR of patients with different coronary lesions and myocardial ischemia were compared,and their correlation with Gensini score and myocardial ischemia was analyzed.The predictive value of TyG index,MHR,and the combined detection of both for coronary lesions and myocardial ischemia was evaluated using receiver operating characteristic(ROC)curves and area under the curve(AUC).Results The TyG index and MHR of the study group were(4.12±0.35)and(0.26±0.08)×109,respectively,which were higher than those of the control group(4.94±0.55)and(0.43±0.12)×109,and the TyG index and MHR of severe coronary artery disease>moderate coronary artery disease>mild coronary artery disease,acute myocardial infarction TyG index,MHR>unstable angina pectoris>stable angina pectoris(P<0.05);TyG index and MHR were positively correlated with Gensini score(r = 0.621,0.635,P<0.05),and positively correlated with the severity of myocardial ischemia(r = 0.617,0.642,P<0.05).The AUC of TyG index and MHR for the joint identification of mild coronary artery disease and moderate coronary artery disease was 0.917,which was greater than the AUCs of 0.749 and 0.832 for the two conditions individually.The AUC of TyG index and MHR for the joint identification of mild to moderate coronary artery disease and severe coronary artery disease was 0.935,which was greater than the AUCs of 0.770 and 0.767 for the two conditions individually(P<0.05).The AUC of TyG index and MHR for the joint identification of stable angina pectoris and unstable angina pectoris was 0.922,which was greater than the AUCs of 0.812 and 0.824 for the two conditions individually.The AUC of TyG index and MHR for the joint identification of stable angina pectoris,unstable angina pectoris,and acute myocardial infarction was 0.913,which was greater than the AUCs of 0.708 and 0.714 for the two conditions individually(P<0.05).Conclusions TyG index and MHR are positively correlated with Gensini score and myocardial ischemia degree.The combined detection of the two has a higher application value in the evaluation of coronary artery disease and myocardial ischemia degree.

Objective:To establish the normal reference range of neurotransmitters in Han-nationality children aged 3-12 in Hubei province.Methods:A prospective study was conducted on healthy Han-nationality children aged 3-12 who took physical examination in Wuhan Children′s Hospital, Hubei province from January to August 2021.The children were asked for their medical histories, and those with neurological diseases, psychiatric diseases, infection, trauma, and a drug history in the past 2 weeks were excluded.The plasma of 324 children (262 males, 62 females; 217 cases in the 3-7 years old, 107 cases in the 8-12 years old) and urine of 391 children (302 males, 89 females; 266 cases in the 3-7 years old, 125 cases in the 8-12 years old) were collected.They ultra performance liquid chromatography-mass spectrometry multiple techniques (UPLC-MS/MS) were used to detect 10 kinds of neurotransmitters (e.g., dopamine, epinephrine, glutamic acid, etc.) in plasma and 8 kinds of neurotransmitters (e.g., dopamine, epinephrine, 5-hydroxyindoleacetic acid, etc.) in random urine.The normal reference range of neurotransmitters in Han-nationality children aged 3-12 in Hubei province was established.The Kruskal- Wallis H test was made for statistical analysis of the differences in neurotransmitter levels among different age groups and gender groups.The neurotransmitter levels between different groups were compared by the Nemenyi test. Results:There were no significant differences in the levels of various neurotransmitters in children of different genders(all P>0.05). There were significant differences in the levels of dopamine, methoxy-norepinephrine, tryptophan and γ-aminobutyric acid in the plasma of children aged 3-7 years and 8-12 years.There were significant differences in the levels of dopamine, epinephrine, norepinephrine, methoxy-norepinephrine, high vanillic acid and 5-hydroxyindoleacetic acid in the random urine between the 3-7 years old group and the 8-12 years old group. Conclusions:The normal reference range of neurotransmitters in Han-nationality children aged 3-12 in Hubei province is established.This study provides reference for clinical practice and lays a foundation for the study of neurotransmitter-related diseases in children.

Objective:To investigate the effect of 1 064-nm Q-switched Nd:YAG laser at different energy settings on cell viability, protease activity and structures of Malassezia furfur. Methods:Cultured standard strains of Malassezia furfur were divided into several groups to be irradiated with 1 064-nm Q-switched Nd:YAG laser at different energies of 0 (control group) , 500, 600, 700, 800 and 900 mJ, respectively. Then, fungal suspensions in the above groups were inoculated onto the Leeming & Notman medium separately. After 7-day culture, the diameter and number of colonies were measured to evaluate the fungal cell viability, the protease activity was measured by using the whole-milk plate medium, and the ultrastructure of Malassezia furfur in each group was observed by transmission electron microscopy. One-way analysis of variance was used for comparisons among multiple groups, least significant difference- t test for multiple comparisons, and Pearson correlation analysis for analyzing correlations of laser energy with colony diameter, number and protease activity. Results:The colony diameter and number both significantly differed among the control group, 500-, 600-, 700-, 800- and 900-mJ groups (colony diameter: 4.05 ± 0.69, 3.76 ± 0.51, 3.28 ± 0.41, 3.09 ± 0.72, 2.54 ± 0.64 and 2.43 ± 0.41 mm, respectively; colony number: 4 787 ± 597, 4 287 ± 761, 1 879 ± 275, 1 082 ± 248 and 209 ± 42, 72 ± 31 colony-forming units, respectively; F = 14.83, 231.85, respectively, both P < 0.05) , and were significantly decreased in the 600-, 700-, 800- and 900-mJ groups compared with the control group (all P < 0.05) . The laser energy was negatively correlated with the colony diameter and number ( r = -0.67, -0.91, respectively, both P < 0.05) . The protease activity significantly differed among the control group, 500-, 700- and 900-mJ groups ( F = 346.60, P < 0.05) , and was significantly lower in the 700- and 900-mJ groups than in the control group (both P < 0.05) . There was a negative correlation between the laser energy and protease activity ( r = -0.94, P < 0.05) . Transmission electron microscopy showed intact fungal structures in the control group, relatively intact fungal structures in the 500-mJ group, and obviously damaged fungal structures in the 600- to 900-mJ groups, and the greater the laser energy, the more severely the fungal structures were damaged. Conclusion:The 1 064-nm Q-switched Nd:YAG laser could affect the cell viability of and protease activity in Malassezia furfur, and damage its structures.

Aim To investigate the mechanism for the inhibitory effect of hydrogen sulfide on the expression of tissue factor(TF)induced by oxidative low-density lipoprotein(ox-LDL)in endothelial cells.Methods Human umbilical vein endothelial cells (HUVECs ) were treated with 50 mg·L-1 ox-LDL in the absence or presence of different concentrations of NaHS (25 , 50,100 and 200 μmol·L-1 )for 24 h.The mRNA expression and protein content of TF in HUVECs were determined by reverse transcription PCR and ELISA, respectively.The content of intracellular reactive oxy-gen species (ROS)was determined by DCFH,an oxi-dative sensitive fluorescent indicator.The activation of nuclear factor-kappaB (NF-κB)was estimated by its expression in nuclear extracts analyzed by Western blot.Results Ox-LDL induced TF mRNA expression and increased TF protein content in HUVECs.The in-crease in intracellular ROS production and the activa-tion of NF-κB were observed in HUVECs treated with ox-LDL.However,NaHS could markedly inhibit the increases in TF mRNA and protein levels induced by ox-LDL.Also the elevation of intracellular ROS pro-duction and the activation of NF-κB elicited by ox-LDL were significantly suppressed by pretreatment with NaHS.In addition,pretreatment with BAY 1 1-7082 (10 μmol·L-1 ),the inhibitor of NF-κB or N-acetyl-L-cysteine(1 mmol·L-1 ),an antioxidant,could also decrease the TF mRNA and protein level as well as ROS production and NF-κB activation induced by ox-LDL in HUVECs,similar to the effects of 200 μmol· L-1 NaHS.Conclusion The mechanism for the in-hibitory effect of H2 S on the ox-LDL- induced TF ex-pression in endothelial cells may be related to inhibi-ting intracellular ROS production and subsequently NF-κB activation.
