Glucagon-like peptide-1 (GLP-1) is a 30-amino acid peptide hormone that is mainly expressed in the intestine and hypothalamus. In recent years, basic and clinical studies have shown that GLP-1 is closely related to lipid metabolism, and it can participate in lipid metabolism by inhibiting fat synthesis, promoting fat differentiation, enhancing cholesterol metabolism, and promoting adipose browning. GLP-1 plays a key role in the occurrence and development of metabolic diseases such as obesity, nonalcoholic fatty liver disease, and atherosclerosis by regulating lipid metabolism. It is expected to become a new target for the treatment of metabolic disorders. The effects of GLP-1 and dual agonists on lipid metabolism also provide a more complete treatment plan for metabolic diseases. This article reviews the recent research progress of GLP-1 in lipid metabolism.

Patients who are bedridden are for a long-time prone to develop bedsores, especially in the hip and sacral areas and limbs, which causes eczema, ulcers, infection and other complications, resulting in pain and more medical costs. Therefore, the medical staff of the Second Affiliated Hospital of Zunyi Medical University designed and developed a kind of anti-bedsore turning pad, and has obtained the national utility model patent (ZL 2021 2 3004923.9), which is suitable for various long-term bedridden patients. The anti-bedsore turning pad includes the center axis of the turning pad, and ventilation pad 1 and ventilation pad 2 designed on the left and right of turning pad center axis. Under the ventilation pad 1 and the ventilation pad 2, the air pad 1 and the air pad 2 are respectively designed. There is a bedspread connected with ventilation pad 1 and ventilation pad 2 on the inflatable pad 1 and the inflatable pad 2. Through the design of inflatable pad 1 and inflatable pad 2, the left and right of the anti-bedsore turning pad can be lowered or raised independently, which is convenient for the patient's body to tilt and turn over, and can significantly reduce the number of nursing staff and the burden of nursing staff when turning over. In addition, it is convenient to replace the force site at any time and reduce the occurrence of pressure ulcers caused by long-term pressure on the force site. Through the design of ventilation cushion 1 and ventilation cushion 2, the internal gas flow of the turning pad can be made, and the ventilation between the patient and the turning pad can be kept dry, so as to reduce the occurrence of eczema, ulcers or infection and other complications, and ultimately reduce the occurrence of bedsores. In addition, through the design of the most superficial limb pad, the patient's limb can be appropriately elevated or massaged, which increases the comfort of the patient. The anti-bedsore turning pad is simple and effective, and can be widely used in long-term bedridden patients.

Objective To investigate the association between serum alkaline phosphatase (ALP) and type 2 diabetes mellitus (T2DM) with nonalcoholic fatty liver disease (NAFLD). Methods A total of 599 patients with T2DM who were hospitalized in Department of Endocrinology, Affiliated Hospital of Jiangsu University, from July 2016 to December 2018 were enrolled as subjects. According to the presence or absence of NAFLD, the patients were divided into NAFLD group with 286 patients and non-NAFLD group with 313 patients, and according to the results of abdominal ultrasound, the patients with NAFLD were divided into mild group with 111 patients, moderate group with 105 patients, and severe group with 70 patients. General clinical data were compared between groups. The independent samples t - test was used for comparison of normally distributed continuous data between two groups, and an analysis of variance was used for comparison between three groups; the Mann-Whitney U test was used for comparison of non-normally distributed continuous data between two groups, and the Kruskal-Wallis H test was used for comparison between three groups; the chi-square test was used for comparison of categorical data between groups. Pearson correlation analysis and Spearman correlation analysis were used to investigate the correlation between ALP and clinical indices, and a logistic regression analysis was used to investigate the influencing factors for NAFLD. Results Compared with the non-NAFLD group, the NAFLD group had significantly higher proportion of patients with history of hypertension ( χ 2 =7.864, P < 0.05), systolic blood pressure ( t =-2.226, P < 0.05), diastolic blood pressure ( t =-3.800, P < 0.05), body mass index (BMI) ( t =-11.842, P < 0.05), waist circumference (WC) ( t =-9.150, P < 0.05), fasting insulin (FINS) ( Z =-6.173, P < 0.05), fasting C-peptide ( t =-5.419, P < 0.05), serum uric acid ( t =-4.957, P < 0.05), low-density lipoprotein cholesterol ( t =-2.702, P < 0.05), triglyceride ( Z =-9.376, P < 0.05), total cholesterol (TC) ( t =-3.016, P < 0.05), Homeostasis Model Assessment of Insulin Resistance (HOMA-IR) ( Z =-5.794, P < 0.05), alanine aminotransferase (ALT) ( Z =-6.737, P < 0.05), aspartate aminotransferase (AST) ( Z =-4.389, P < 0.05), gamma-glutamyl transpeptidase (GGT) ( Z =-7.764, P < 0.05), and ALP ( t =-2.833, P < 0.05), as well as significantly lower age ( t =2.184, P < 0.05) and high-density lipoprotein cholesterol ( Z =-5.273, P < 0.05). The severity of NAFLD (mild, moderate or severe) was positively correlated with age ( r s =0.140, P < 0.05), BMI ( r s =0.239, P < 0.05), WC ( r s =0.222, P < 0.05), FINS ( r s =0.191, P < 0.05), HOMA-IR ( r s =0.218, P < 0.05), ALT ( r s =0.188, P < 0.05), AST ( r s =0.279, P < 0.05), GGT ( r s =0.202, P < 0.05), and ALP ( r s =0.361, P < 0.05). In the patients with T2DM and NAFLD, ALP was positively correlated with HbAlc ( r =0.149, P < 0.05), fasting plasma glucose ( r =0.146, P < 0.05), HOMA-IR ( r s =0.132, P < 0.05), TC ( r =0.151, P < 0.05), ALT ( r s =0.210, P < 0.05), AST ( r s =0.192, P < 0.05), and GGT ( r s =0.297, P < 0.05). The logistic regression analysis showed that ALP was an influencing factor for NAFLD in patients with T2DM (odds ratio=1.013, 95% confidence interval: 1.004-1.023, P < 0.05). Conclusion Elevated serum ALP is a risk factor for T2DM with NAFLD and is closely associated with hyperglycemia, insulin resistance, and hyperlipemia, and ALP may play a role in the development and progression of T2DM and NAFLD.

Objective: To construct and identify an overexpression recombinant adenovirus vector carrying the mouse PTG gene(NM＿016854), and to lay a foundation for in-depth study of the function of PTG.

Conclusion The recombinant adenovirus vector carrying mouse PTG gene is successfully constructed, and the expression of PTG gene in hepatocytes is effectively up regulated.

Objective:To identify key genes and their potential biological mechanisms in the progression of non-alcoholic fatty liver disease (NAFLD) using bioinformatics technology.Methods:Genes differentially expressed in simple non-alcoholic fatty liver disease (NAFL) and non-alcoholic steatohepatitis (NASH) were analyzed by integrating NAFLD-related sequencing datasets GSE135251 and GSE167523 from the Gene Expression Omnibus (GEO) datebase. Gene Ontology (GO) functional enrichment analysis, Kyoto Encyclopedia of Genes and Genomes (KEGG) and Reactome signaling pathway analysis were performed. Key genes were identified by STRING database and Cytoscape3.7.2 software, and the expression of key genes under different fibrosis grades and activity scores was observed. In addition, the expression of key genes in different cell clusters was observed based on the single-cell RNA-seq dataset of NAFLD mice.Results:Bioinformatics methods were used to obtain 97 common differential genes in NAFLD from two datasets. GO functional enrichment analysis was mainly performed in Extracellular Matrix (ECM) tissues. The main signaling pathway is ECM-receptor interaction. Five key genes were identified based on PPI network and Cytoscape software: COL1A1, THBS2, CXCL8, THY1 and LOXL1. The expression of key genes was significantly positively correlated with fibrosis grade and activity score, indicating that they were closely related to the progression of NAFLD. These key genes are highly expressed in hepatic stellate cells (HSCs) and natural killer/T cells (NK/T cells).Conclusion:In this study, bioinformatics technology was used to identify five key genes that may be involved in the NAFL-NASH transformation, suggesting that the ECM-receptor interaction signaling pathway may be a key molecular mechanism of NAFLD disease progression.

Oxytocin is a classic neuropeptide hormone. In recent years, basic and clinical researches have shown that oxytocin is involved in the regulation of blood glucose homeostasis by protecting islet β cells, promoting insulin secretion and peripheral tissue glucose uptake. This article reviews the recent evidence of the linkage between oxytocin and diabetes mellitus.

Objective To explore the effect of the position of the biliary stents on the short?term and long?term effects of the patients with low malignant obstructive jaundice after treatment.Methods Seventy?eight patients with low?grade malignant obstructive jaundice diagnosed in Jiangyin Hospital Affiliated to Medical College of Southeast University who underwent biliary stenting were enrolled as the study object.According to the placement of the biliary stents,the stents were divided into the spanning group and the non?crossing group.The baseline data and related serological indexes were recorded,and the changes of jaundice between the two groups were compared by repeated measurements.All patients were followed up for 48 weeks.Multivariate Cox regression analysis was applied on the risk factors that might affect the prognosis of patients, and the degree of influence of various factors on the prognosis of patients was further evaluated.Results Repeated measures analysis showed that the biochemical indicators of the spanning group and the non?crossing group showed a significant downward trend and the difference was statistically significant (TBil: Fintra?group＝9.392,Pintra?group＝0.000; DBil: Fintra?group＝7.581,Pintra?group＝0.001).Among them,the total bilirubin (TBil) (Preoperative: (318.69±101.13) μmol／L,1 week after surgery: (135.98 ±63.61) μmol／L,2 weeks after surgery: (60.21±24.81) μmol／L) was lower than the non?crossing group preoperative: (309.07±109.97) μmol／L,1 week after surgery: (158.87±66.92) μmol／L,2 weeks after surgery: (75.91 ± 20.46) μmol／L), and the difference was statistically significant ( Finter?group ＝3.362, Pinter?group＝0.041).The direct bilirubin ( DBil) ( Preoperative: (171.93 ± 73.01) μmol／L,1 week after surgery: (90.38± 57.33) μmol／L,2 weeks after surgery:(36.64± 18.95) μmol／L) was lower than the non?crossing group ( Preoperative: ( 174.53 ± 82.74) μmol／L,1 week after surgery: ( 107.85 ± 49.07) μmol／L,2 weeks after surgery: ( 37.87 ± 14.55 ) μmol／L.The difference was statistically significant (Finter?group＝6.284,Pinter?group＝0.003).There was an interaction between the treatment regimen and treatment time (1 week after surgery and 2 weeks after surgery) (TBil: Finteraction＝12.262,Pinteraction＝0.000; DBil:Finteraction＝10.254,Pinteraction＝0.000).The results of the multi factor Cox proportional hazard model of the spanning group and the non?crossing group showed that the ALP, DBil, TBil and lymphatic metastasis of malignant tumor were the two independent risk factors that affect the prognosis.However, the pancreatic cancer,ALT and age in the spanning group across the ampulla also have a certain effect on the prognosis of the patients.Conclusion The effect of the placement of biliary stents across the Vater ampullary was more obvious in the short term on the decline of bilirubin.But in the long term,there was no significant difference in the prognosis of patients with biliary stenting position.ALP,TBil,DBil,and disease classification were all important risk factors affecting the prognosis of two groups of patients

Objective There are few researches for the serum betatrophin level and diabetic nephropathy (DN) recently.The aim of this study was to investigate the change of serum betatrophin level and the correlation of serum betatrophin and urinary albumin-to-creatintine ratio (UACR) in patients with type 2 diabetes mellitus (T2DM).Methods A total of 150 Chinese subjects from Mar 2013 to Jul 2016 were enrolled in the study, including 90 patients with type 2 diabetes and 60 healthy controls.According to the level of UACR, the diabetic patients were divided into two groups:normal UACR group (UACR<30 mg/g, n=60) and abnormal UACR group(UACR>30 mg/g, n=30).Serum betatrophin was measured by enzyme linked immunosorbent assay (ELISA).UACR was measured by turbidimetric inhibition immune assay.Blood glucose blood lipid were measured simultaneously.Results The serum betatrophin level was significantly higher in abnormal UACR group than that in normal UACR group[677.37±59.02 vs 486.13±41.22 pg/mL, P<0.05];Serum betatrophin level in T2DM patients was positively correlated with age (r=0.246), waist hip ratio (WHR) (r=0.240), fasting blood glucose (FPG) (r=0.234), 2 hour plasma glucose (2hPG) (r=0.363), glycosylated hemoglobin (HbA1c) (r=0.346), fasting insulin (FINS) (r=0.249), insulin resistance index (HOMA-IR) (r=0.309), blood urea nitrogen (BUN) (r=0.223), creatinine (CREA) (r=0.277) and UACR (r=0.244) (P<0.05),and negatively correlated with glomerular filtration rate (GFR) (r=0.308) (P<0.01).Serum betatrophin level in normal UACR group was positively correlated with age, HbA1c and UACR (P<0.05);Serum betatrophin level in abnormal UACR group was positively correlated with WHR (r=0.504), 2hPG (r=0.600), HbA1c (r=0.449), HOMA-IR (r=0.395) (P<0.05).The WHR, HbA1c, HOMA-IR and GFR were the influential factors of the serum betatrophin level.Conclusion The level of serum betatrophin was significantly increased in T2DM patients with albuminuria, which suggests that the betatrophin might play an important role in the pathogenesis of DN.
