Objective To investigate and analyze the relationships among glucagon-like peptide-1 (GLP-1) level, chronic inflammation, and atherosclerosis in patients with non-alcoholic fatty liver disease (NAFLD). Methods From October 2016 to February 2017, using cross-sectional investigation, the GLP-1 level, chronic inflammation, and atherosclerosis were investigated in 80 subjects (40 NAFLD patients in NAFLD group, and 40 non-fatty liver disease participants in control group) who underwent physical examination at Xi’an Road Community Hospital. Results Compared with those in the control group, GLP-1 fasting level in patients with NAFLD [(9.09±1.03) vs. (9.15±1.06) pmol/L, P=0.807] and postprandial plasma GLP-1 [(15.96±3.37) vs. (17.46±4.76) pmol/L, P=0.108] had no changes. The correlations of GLP-1 level with chronic inflammation and insulin resistance (IR) were not significant either. The increased risk of carotid intima-media thickness related cardiovascular disease (CVD) in the NAFLD group was greater than that in the control group, and the difference was statistically significant [22 (55.0%)vs.13 (32.5%), P=0.043]. When the plasma lipoprotein-associated phospholipase A2 level increased, the risk of NAFLD increased [odd ratio (OR)=1.16, 95% confidence interval (CI) (1.02, 1.32), P=0.023]. Plasma ceramide kinase (CERK) in the NAFLD group was lower than that in the control group, and the difference was statistically significant [(12.36±2.45) vs. (18.33±3.71) ng/mL, P<0.001]. When the plasma CERK level of the fasting plasma was elevated, the risk of NAFLD decreased [OR=0.30, 95%CI (0.12, 0.78), P=0.014]. The homeostasis model assessment of insulin resistance (HOMA-IR) in the NAFLD group was higher than that in the control group, and the difference was statistically significant (2.46±2.53 vs. 1.11±0.66, P=0.002). The Matsuda index in the NAFLD group was less than that in the control group, and the difference was statistically significant (5.88±4.09 vs. 10.46±7.90, P=0.002). When HOMA-IR increased, the risk of NAFLD increased [OR=2.75, 95%CI (2.49, 3.12), P=0.036]. Conclusions Plasma GLP-1 level is not a sensitive indicator of chronic inflammation and IR in patients with NAFLD. Patients with NAFLD are in an increased risk of atherosclerosis and CVD. It suggests that NAFLD might be involved in chronic inflammation and IR. Chronic inflammation can cause IR, and then chronic inflammation and IR can cause NAFLD and subclinical atherosclerosis. In return for this, NAFLD increases chronic inflammation and IR.
1-methyl-6,7-dihydroxy-1,2,3,4-tetrahydroisoquinoline (Sal) is a kind of catechol isoquinoline compound, which mainly exists in mammalian brain and performs a variety of biological functions. Through in vivo metabolism, Sal can be transformed into endogenous neurotoxins and can participate the occurrence of Parkinson’s disease (PD). This has attracted widespread concern of researchers. Recently, many research works have shown that Sal may lead to alcohol addiction and regulate hormone release of the neuroendocrine system, which indicated that it is a potential regulator of dopaminergic neurons. In this paper, we discuss the neural functions of Sal on the above aspects, and wish to provide some theoretical supports for further research on its mechanism.
ObjectiveTo summarize the research progress of magnetic resonance imaging (MRI) for diagnosis of nonalcoholic steatohepatitis (NASH).MethodRelevant literatures at home and abroad were collected to make an review, then summarized the research status and progress of MRI for diagnosis of NASH. Their advantages and disadvantages were summarized.ResultsA variety of MRI techniques, including MR elastography, gadolinium-ethoxybenzyldiethylenetriaminepentaacetic acid (Gd-EOB-DTPA) enhanced MRI, diffusion-weighted MR imaging, and quantitative MR imaging of fat and iron, had been widely used in diagnosing NASH and shown to have some value. However, there were currently no effective MRI techniques recommended for diagnosing NASH.ConclusionsMRI plays an important role in noninvasive assessment of NASH. Future studies are needed to investigate more efficient noninvasive biomarkers and models consisting of imaging and non-imaging biomarkers for diagnosing NASH, to reduce unnecessary biopsies.

Objectives To compare umbilical cord daily care protocol in the current clinical setting in which 75% alcohol sterile is used daily for the umbilical and surrounding skins with the WHO-recommended method (dry and clean). Methods A total of 283 full-term newborns were randomly divided into two groups: the trial group (n=181) receiving WHO “dry and clean” protocol that the umbilical cord was open to air (with losing clothes), cleaned by clear water instead of alcohol. The control group (n=102) used the traditional method that after the newborns’ bathing, the umbilical cord and surrounding skins were sterilized with 75% alcohol. The basic condition of the newborns, umbilical departure time and complications around the navel were assessed. And bacterial culture from the newborns’ skins was observed. Results There were no significant differences in departure time of the umbilical cord (7.64±3.29 day vs. 8.50±3.45 days t=1.82, Pgt;0.05), complications (6 patients with slight omphalitis in the trial group and 2 patients with slight omphalitis in the control group), and the skin flora culture between the two groups. The umbilical cord of the newborns dropped off safely. And no fever was found. Conclusion This study does not support that 75% alcohol can prevent the umbilical cord from being infected. Keeping the umbilical cord and surrounding skins dry is important for infection control.
Objective To investigate the effects of insulin-like growth factor 1（IGF-1） and ethanol (EtOH) on the changes in the osteoblast proliferation and the osteoblast function under the normal serum concentration and serum starvationMethodsThe osteoblasts harvested from the SD rat calvaria were incubated in the following six conditions according to the supplements in DMEM: the F15group：15% newborn calf serum (NCS)； the F15/EtOH group：100 mmol/L of EtOH added to 15% NCS； the F2 group：2% NCS； the F2/EtOH group：100 mmol/L of EtOH added to 2% NCS；the F2/IGF-1 group：25ng/ml of IGF-1 added to 2% NCS；the F2/IGF-1/EtOH group：100 mmol/L EtOH added to 25 ng/ml IGF-1 and 2% NCS. The osteoblasts were analyzed by the MTTassay, alkaline phosphatase（ALP） activity, and RTPCR at 24, 48, 72 and 96h ours after the culture. Results The absorbance (A), the ALP activity, and the expression of BGP mRNA (the proliferation and function indicators of the osteoblasts) were significantly decreased in the F15/EtOH group at all the time points when compared with those in the F15the group (P＜ 0.05); the above 3 indicators were significantly decreased in the F2 groupwhen compared with those in the F15 group (P＜0.05); they were significantly decreased in the F2/EtOH group when compared with those in the F2 group (P＜0.05); however, the indicators in the F2/IGF-1 group were significantly increased when compared with those in the F2 group (P＜0.05); the A value in the F2/IGF-1/EtOH group was not significantly decreased when compared with that in the F2/IGF-1 group, with an exception of the A value at 24 hours (P＞0.05); however, ALP and BGP mRNA were significantly decreased (P＜0.05). All the indicators were significantly increased when compared with those in the F2/EtOH group (P＜0.05) Conclusion Ethanol can inhibit the osteoblast proliferation and the osteoblast function, and can increase the inhibition when the osteoblasts were cultured under the serum starvation. This may be one of the mechanisms for alcoholic bone disease. IGF-1 can prevent the inhibition of the osteoblasts under the serum starvation and counteract the ethanolinduced proliferation inhibition; therefore, IGF-1 is an alternaive therapeutic intervention for alcoholic bone disease.

During the past 42 months, a total of 53 patients with primary hepatic carcinoma (PHC) had been treated by fine needle percutanous ethanol intratumor infiltration (group P) and ethanol infiltration combined with intrahepatoportal chemotherapy around carcinoma, using adriamycin (group PA) or using adriamycin, carboplytin mitomycin and 5-Fu (group PC) for two courses. Result showed that 16cases were complete remission and 21 cases were part remission. The overall response rate was 69.8%, with a median survival duration of 10.1 months. After clinical contrast among three groups, the response rate in PA group exceeded P and PC group and adverse reactions was lower than PC group. The authors belive that this method might be a remedial measure for patients who are unsuitable for major surgery.
ObjectiveTo review the research progress of pathogenesis and genetics of alcohol-induced osteonecrosis of the femoral head (AIONFH). MethodsThe relevant domestic and foreign literature in recent years was extensively reviewed. The pathogenesis, the relationship between gene polymorphism and susceptibility, the related factors of disease progression, and the potential therapeutic targets of AIONFH were summarized. ResultsAIONFH is a refractory orthopedic disease caused by excessive drinking, seriously affecting the daily life of patients due to its high disability rate. The pathogenesis of AIONFH includes lipid metabolism disorder, endothelial dysfunction, bone homeostasis imbalance, and et al. Gene polymorphism and non-coding RNA are also involved. The hematological and molecular changes involved in AIONFH may be used as early diagnostic markers and potential therapeutic targets of the disease. ConclusionThe pathogenesis of AIONFH has not been fully elucidated. Research based on genetics, including gene polymorphism and non-coding RNA, combined with next-generation sequencing technology, may provide directions for future research on the mechanism and discovery of potential therapeutic targets.
摘要:目的:探讨加兰他敏对急性酒精中毒大鼠海马神经元N甲基D天冬氨酸(NMDA)·R2B的影响。 方法:将60只大鼠分为对照组、酒精组及加兰他敏组,每组各20只。酒精组以50％(v/v) 酒精12 mL/kg灌胃两次/日,共7d。加兰他敏组酒精(浓度、剂量同上)灌胃的同时腹腔注射加兰他敏2mg/kg一次/日,共7d。对照组以等量生理盐水灌胃。实验第8天取大鼠海马区做苏木精伊红（HE）染色,观察海马区的病理学变化;免疫组织化学采用SABC法,观察海马区神经元NR2B的表达。 结果: 病理学观察结果：对照组海马区神经细胞排列整齐,胞质淡染,无变性、坏死;酒精组神经细胞层次不清、排列松散、细胞数量减少,部分细胞变性;加兰他敏组神经细胞层次较清、排列较密,细胞数目较酒精组增; 免疫组织化学结果：酒精组与对照组比较NR2B阳性表达细胞数量明显减少(Plt;0.01);加兰他敏组与酒精组比较NR2B阳性表达细胞数量明显增高(Plt;0.05);加兰他敏组与对照组比较NR2B表达细胞数量无明显差异(Pgt;005)。 结论: 急性酒精中毒与海马区神经细胞的NR2B表达下调有关;加兰他敏具有保护急性酒精中毒导致的大鼠海马区神经细胞毒性的作用,其机制可能与加兰他敏上调NR2B的表达有关。Abstract: Objective: To study the effects of galanthamine on NmethylDaspartic acid receptor 2B (NMDAR2B, NR2B) in the hippocampus (HIP) of acute alcoholism rats. Methods: Total of 60 wistar male rats were randomly divided into control group, ethanol group and glanthamine group, and there were 20 rats in each group. The rats in ethanol group were given by intragastric administration with 50% alcohol (v/v) on the dose of 12 ml/kg twice per day, in control group were given by same dose of saline, and in galanthamine group were treated by intragastric administration with the same concentration and dosage of alcohol as in ethanol group and peritoneal injection with 2 mg/kg of galanthamine once per day for 7 days. In eighth day of experiment, the rats were sacrificed under etherization, and pathological changes of HIP’s zone of rat were observed by HEstaining, and expression of NR2B in neurons of HIP’s zone by immunohistochemical SABC method. Results: The results observed by histopathology showed that in control group, neurons of HIP’s zone lined up in order, cytoplasm had faint staining, and were no degeneration and necrosis; in ethanol group, nerve cells’ layer was unclear, structure was loose, cell number reduced and part of cells degenerated; in galanthamine group, layer of neurons was comparatively clear and arrangement was comparatively dense, and the cell number increased obviously more than ethanol group. The results detected by Immunohistochemistry for NR2B showed that the cell number with expression of NR2B in the HIP’s zone decreased significantly in the ethanol group than in the control group (Plt;0.01), increased in the galanthamine group than in the ethanol group (Plt;0.05), and had no difference between the galanthamin and control group (Pgt;0.05). Conclusion: Acute alcoholism may relate to down regulation of expression of neuron’s NR2B in HIP’s zone;The galanthamin has role of protection for neuron in HIP’s zone induced by toxicity of acute alcoholism, and its mechanism may relate to galanthamin upregulation NR2B expression.
