To investigate the plasma thioredoxin-interacting protein ( TXNIP ) levels in different glucose tolerance groups and discuss the relationship between TXNIP and insulin resistance/β-cell dysfunction in diabetes and prediabetes, and to investigate the potential relationship between TXNIP and interleukin-1β( IL-1β) . According to oral glucose tolerance test, 93 participants were divided into 3 groups:diabetes mellitus group, prediabetes group, and normal glucose tolerance group. Plasma TXNIP, IL-1β, and other biochemical indices were measured. The relationship between TXNIP and glucose, IL-1β, homeostasis model assessment for insulin resistance ( HOMA-IR) , and homeostasis model assessment forβcell function ( HOMA-β) were analyzed by using multiple linear regression techniques and Pearson’s linear correlation analysis. Plasma TXNIP level was higher in prediabetes group compared with normal glucose tolerance group, but lower in prediabetes group compared with diabetes mellitus group[(355. 35±31. 88 vs 274. 36±33. 86, 426. 16±63. 15)pg/ml, P<0. 01 or P<0. 05]. TXNIP was positively correlated with IL-1βand HOMA-IR, but negatively correlated with HOMA-β. Multiple linear regression analysis indicated that IL-1βexerted significant influence on TXNIP ( P<0. 05 ). Plasma TXNIP level is affected by blood glucose concentration. There is a close relationship between TXNIP and IL-1β. In prediabetes patient, the TXNIP levels have already been raised.

Life education is an important course for cultivating students'comprehensive quality,shaping their personality,and inheriting civilization.This paper compared the historical evolution,teaching contents,and practical approaches of life education between Chinese and American university students,and summarized the following problems faced by life education for Chinese university students:national legislative support and financial support can still be improved;there were few independent life education courses offered in colleges and universities and lack of practical activities;education on setbacks,adversity,and life values,and the students'ability to independently solve difficulties needed to be improved;the lack of death education and other main challenges.Afterwards,this paper summarized the development of life education in the United States,life education courses were widely and comprehensively offered and had a long history;the content emphasized education on character,setbacks,and safety,more importantly,guided students to face life and death,and practical courses such as end-of-life care drills were provided to establish a positive outlook on life and death for students;the government had introduced laws and regulations to support,and families attached importance to cultivating children's self-care ability,Finally,it proposed that the life education of Chinese university students should be based on their own cultural and social background:universities should seek breakthroughs in the construction of life education courses,society should form a joint effort to create the atmosphere of life education,and university students should reflect on life education issues independently.

Objective To evaluate the safety and efficiency of domestic snare applied during retrograde percutaneous coronary intervention (PCI) for chronic total occlusion (CTO) lesions.Methods A total of 27 patients who underwent retrograde PCI for CTO and used domestic snare during the procedure were enrolled in our study from March 2012 to November 2016.Clinical data, angiographic characteristics and PCI details were collected.Clinical data, characteristics of CTO lesion, effect of the domestic snare and snaring time were retrospectively analyzed.Special complications related to the domestic snare and major adverse cardiovascular events (MACE) were also documented.Results Domestic snare was used in all the procedures, which included facillitating the micro-catheter to pass through the CTO lesions in 6 patients and assisting the RG3/rotational guide-wire externalization in all the 27 patients.Mean snaring time was 3.5±5.4 minutes.Stents were successfully implanted in 26 patients except in 1 patient who failed to receive stent implantation for severe coronary calcification.No complications including coronary dissection, fracture of guide-wire and unreleased snare happened during the procedures and no MACE occurred during hospitalization.Conclusions Domestic snare facilitates retrograde micro-catheter crossing CTO lesions and retrograde guide-wire entering the guiding catheter and externalization.It is a simple, safe and efficient method.

Objective: To explore the occurrence of cognitive impairment in Chinese heart failure (HF) patients and it's impact on prognosis. Methods: In this prospective observational study, a total of 990 HF patients were enrolled from 24 hospitals in China during December 2012 to November 2014. All patients were administrated with the interview-format Montreal Cognitive Assessment (MoCA), according to which they were divided into MoCA<26 (with cognitive impairment) group and MoCA≥26 (without cognitive impairment) group. Baseline data were collected and a 1-year follow up was carried out. Univariate and multivariate logistic or Cox regression were performed for 1-year outcomes. Results: Cognitive impairment was evidenced in 628 patients (63.4%) and they were more likely to be older, female, and with higher proportion of New York Heart Association(NYHA) class Ⅲ-Ⅳ, chronic obstructive pulmonary disease (COPD), ischemic heart disease, while body mass index (BMI), education level, and medical insurance rate were lower (all P<0.05) as compared to patients in MoCA≥26 group. The rate of percutaneous intervention, device implantation, cardiac surgery and evidence-based medications were significantly lower in MoCA<26 group than in MoCA≥26 group (all P<0.05). During the 1-year follow up, patients in the MoCA<26 group had higher all-cause mortality (10.2%(64/628) vs. 2.2%(8/362), P<0.01), cardiovascular mortality (5.9%(37/628) vs. 0.8%(3/362), P<0.01) and major adverse cardiac and cerebrovascular events (MACCE) (9.6%(60/628) vs. 2.5%(8/362), P<0.01) than patients in the MoCA≥26 group. In univariate regression, MoCA<26 was associated with increased all-cause mortality (HR(95%CI):4.739(2.272-9.885), P<0.01), cardiovascular mortality (HR(95%CI):7.258(2.237-23.548), P=0.001) and MACCE (OR(95%CI):4.143(2.031-8.453), P<0.01). After adjustment by multivariate regression, MoCA<26 was indicated as an independent risk factor for all-cause mortality (HR(95%CI): 6.387(2.533-16.104), P<0.01), cardiovascular mortality (HR(95%CI): 10.848(2.586-45.506), P=0.001) and MACCE (OR(95%CI): 4.081(1.299-12.816), P=0.016), while not for re-hospitalization for HF (OR(95%CI):1.010(0.700-1.457), P=0.957). Conclusions Cognitive impairment is common in HF patients,and it is an independent prognostic factor for 1-year outcomes. Routine cognitive function assessment and active intervention are thus recommended for HF patients.

In response to the current shift in the main content and research focus of life education， which is gradually shifting from the behavioural norms of “health and safety” to thinking about the essence of life and issues of life and death. Drawing on the theoretical resources of the political philosophy of life， it was pointed out that the internalization of “life” has led to the incidence of “burnout” and depression. Faced with the technological rationalism of contemporary society， how to deal with external technological training was the real problem that life education needs to solve. For life education， it was necessary to study how to reemphasize the practical dimension， as well as expand the theme of “health and safety” from simple behavioural norms to ways of dealing with modern society and showcasing life forms.

ObjectiveTo investigate the mechanism of Tangbikang dry paste in the prevention and treatment of type 2 diabetic peripheral neuropathy （DPN） based on the glyoxalase-1 （GLO-1）/advanced glycation end products （AGE）/receptor for advanced glycation end products （RAGE） pathway. MethodsA total of 56 Sprague-Dawley rats were randomly divided， with eight assigned to the normal group. The remaining 48 rats were fed a high-fat diet combined with intraperitoneal injection of streptozotocin （STZ） to induce a type 2 diabetes mellitus （T2DM） model. Based on blood glucose levels， the rats were randomly assigned to the model group， Tanglin group （13.5 mg·kg^-1）， metformin group （135 mg·kg^-1）， and Tangbikang dry paste low-， medium-， and high-dose groups （3， 6， 12 g·kg^-1）. Successful modeling of DPN was confirmed by a decrease in mechanical pain threshold in the model group at week 4. Fasting blood glucose， body weight， and mechanical pain threshold were measured every 4 weeks. After 16 weeks of intervention， the pathological morphology of the sciatic nerve was observed using hematoxylin-eosin （HE） staining. The expression of RAGE， AGE， protein kinase C （PKC）， and collagen （COL） in the sciatic nerve was assessed by immunohistochemistry. The mRNA expression of RAGE， PKC， Toll-like receptor （TLR）， COL， and GLO-1 was detected using real-time quantitative PCR （Real-time PCR）. Serum levels of aspartate aminotransferase （AST）， alanine aminotransferase （ALT）， creatinine （CREA）， urea （UREA）， interleukin-6 （IL-6）， and tumor necrosis factor （TNF）-α were measured by enzyme-linked immunosorbent assay （ELISA）. ResultsCompared with the normal group， the model group showed significantly increased fasting blood glucose （P<0.01）， decreased body weight and mechanical pain threshold （P<0.01）， and elevated serum AST， ALT， CREA， UREA， IL-6， and TNF-α levels （P<0.01）. The expression of RAGE， AGE， and PKC in the sciatic nerve was significantly increased （P<0.01）， while COL expression was decreased （P<0.01）. The mRNA expression of TLR， RAGE， and PKC was upregulated （P<0.01）， whereas COL and GLO-1 mRNA levels were downregulated （P<0.01）. Histological examination showed irregular nerve morphology， axonal alterations， and myelin degeneration. Compared with the model group， fasting blood glucose levels in the Tangbikang dry paste high-dose group at all time points and in the medium-dose group at weeks 4 and 16 were significantly reduced （P<0.05， P<0.01）. No significant changes in body weight were observed across all Tangbikang dose groups. The mechanical pain threshold was elevated at different time points after administration in all Tangbikang groups （P<0.05， P<0.01）. Serum IL-6 and TNF-α levels were decreased in all dose groups （P<0.05， P<0.01）. The expression of RAGE， AGE， and PKC in the sciatic nerve was reduced （P<0.01）， while COL expression was increased （P<0.01）. The mRNA expression of TLR， RAGE， and PKC was downregulated （P<0.01）， whereas GLO-1 mRNA expression was upregulated （P<0.05， P<0.01）. Additionally， COL mRNA expression was significantly increased in the low- and high-dose groups （P<0.01）. Pathological changes in the sciatic nerve were milder in all Tangbikang groups compared to the model group. ConclusionTangbikang dry paste significantly improves DPN， and its mechanism may be associated with the regulation of the GLO-1/AGE/RAGE signaling pathway.

ObjectiveTo evaluate the efficacy and safety of An'erning granules in the treatment of community-acquired pneumonia in children. MethodA randomized， double-blind， single-simulation， placebo-controlled trial was designed in this study. The children were randomly assigned into an observation group （An'erning granules combined with ceftriaxone sodium） and a control group （An'erning granules placebo combined with ceftriaxone sodium） according to the ratio of 2∶1. The disease cure rate was taken as the main indicator of efficacy， and the safety of An'erning granules was observed. ResultA total of 206 children （137 in the observation group and 69 in the control group） were included in this study. Before treatment， the age， sex， body height， body weight， diagnosis time of pneumonia， and symptom and sign scores had no significant differences between the two groups. After 8 days of continuous medication， the observation group［70.80%（97/137）］ had higher cure rate than the control group［56.52%（39/69）］（χ²=4.17，P<0.05） and total effective rate of chest X-ray ［97.98%（97/99）］ than the control group［86.27%（44/51）］ （χ²=12.98，P<0.01）. The observation group was superior to the control group in the alleviation of TCM syndrome under the condition of 0-3 g dose stratification on day 3 of medication （P<0.01）. The recovery time， time to complete fever abatement， time to fever abatement and expectoration alleviation， rate of conversion to severe case， and reduction in the frequency of antibiotic use showed no significant differences between the two groups. In terms of safety， 13 and 7 adverse events occurred in the observation group and control group， respectively， which were relieved or disappeared after drug withdrawal or symptomatic treatment and showed no significant difference between the two groups. ConclusionIntravenous drip of ceftriaxone sodium combined with An'erning granules is effective in the treatment of community-acquired pneumonia in children. It can accelerate the absorption of pulmonary inflammation， alleviate the clinical symptoms in a short time for young children or the children with mild symptoms， and is safe in clinical application.

ObjectiveTo explore the therapeutic effect and mechanism of the Danhe granules on hypercholesterolemia rats by observing the changes in the efficacy indicators and the levels of proteins related to the cholesterol metabolism pathway in the rats under the intervention of Danhe granules. MethodSD rats were randomly assigned to either the blank group or the model group based on their body weight. The blank group had normal chow diets， while the model group was fed high-fat diets for seven weeks. One week after the establishment of the model， the content of the serum total cholesterol （TC） in the model rats was detected. According to the TC value， the model group was further randomly divided into a control group， pravastatin sodium tablet group（4.02 mg·kg^-1）， Xuezhikang capsule group（0.12 g·kg^-1）， high-dose， middle-dose， and low-dose groups of Danhe granules（4.536， 2.268， 1.134 g·kg^-1）. After grouping the model groups， each treatment group received continuous oral gavage for six weeks， with weekly measurements of body weight and food intake （the difference between feed intake and feed surplus）. Six weeks later， the levels of serum TC， triglyceride （TG）， low-density lipoprotein cholesterol （LDL-C）， and high-density lipoprotein cholesterol （HDL-C） were measured. The liver pathology and lipid droplet distribution were evaluated by hematoxylin-eosin （HE） staining and oil red O staining， with scoring and calculation conducted. Rat liver tissue was collected， and western blot and immunohistochemistry （IHC） were used to detect the expression levels of cholesterol metabolism-related proteins namely phosphorylated adenosine 5'-monophosphate （AMP）-activated protein kinase （p-AMPK）， AMPK， 3-hydroxy-3-methyl glutaryl coenzyme A reductase （HMGCR）， low-density lipoprotein receptor （LDLR）， cholesterol 7α-hydroxylase （CYP7A1）， Acyl-coenzyme A： cholesterol acyltransferase 2 （ACAT2）， and apolipoprotein B （ApoB） in hypercholesterolemia rats. ResultCompared with the blank group， the model group showed a significantly higher level of serum TC （P<0.01）. The TG level had no significant change， and the HDL-C level was significantly decreased （P<0.05）. The liver index， steatosis score， total score of pathological state， and the positive area ratio of oil red O staining were significantly increased （P<0.01）， and the protein expression levels of p-AMPK， p-AMPK/AMPK， LDLR， and CYP7A1 were significantly decreased （P<0.05， P<0.01）， while the protein expression levels of AMPK， HMGCR， and ACAT2 were significantly increased （P<0.05， P<0.01）. Compared with the model group， the TC level in each dose group of Danhe granules was significantly decreased （P<0.05）， and the positive area ratio of oil red O staining in the pravastatin sodium tablet group and medium-dose group of Danhe granules was significantly decreased （P<0.05）. In each administration group， the protein expression levels of p-AMPK and p-AMPK/AMPK were significantly increased （P<0.05， P<0.01）， and the levels of HMGCR and ACAT2 were significantly decreased （P<0.01）. The ApoB level showed a downward trend. The CYP7A1 level in the pravastatin sodium tablet group and each dose group of Danhe granules was significantly increased （P<0.05， P<0.01）， and the LDLR level in the pravastatin sodium tablet group， Xuezhikang capsule group， and high-dose and medium-dose groups of Danhe granules was significantly increased （P<0.05， P<0.01）. ConclusionDanhe granules can reduce serum TC levels and improve hepatic steatosis. It may activate AMPK， down-regulate the expression of HMGCR， and inhibit cholesterol synthesis. It can also up-regulate the expression of LDLR and CYP7A1， promote cholesterol uptake and excretion， down-regulate the expression of ACAT2 and ApoB， reduce cholesterol absorption and assembly of LDL and other lipoproteins， and thus play a role in the treatment of hypercholesterolemia.
