Modern Interventional Diagnosis and Treatment in Gastroenterology.2024;29(2):122-125,134. doi:10.3969/j.issn.1672-2159.2024.02.002

Objective To investigate the relationship between serum lipid profiles and colorectal adenomas,and to benefit the prevention of colorectal cancer.Methods This study retrospectively analyzes the serum lipid profiles and clinical parameters of 2,960 patients who were diagnosed with colorectal adenomas,and 3,156 individuals without colorectal adenomas in Meizhou People's Hospital from May 2018 to May 2020.The association between serum lipid profiles and colorectal adenoma was evaluated by Logistic regression analysis.Results It was observed that the serum levels of total cholesterol(TC),triglyceride(TG),low density lipoprotein cholesterol(LDL-C)and apoliprotein B(ApoB)were significantly elevated in patients with colorectal adenomas.Dyslipidemia was more prevalent in adenoma cases than in controls.The Logistic regression analysis suggested that serum TC and TG levels were positively associated with the occurrence of colorectal adenomas.Conclusion Elevated serum TG and TC levels are independent risk factors for adenoma,and adenoma patients with elevated serum TG and TC levels may be more likely to develop high-risk adenoma.

Objective To explore the risk factors for the occurrence of adenomatous polyps in melanosis coli(MC),and to construct and validate a risk prediction model for the occurrence of adenomatous polyps in MC.Methods The clinical data of patients with melanosis coli who underwent colonoscopy in our hospital were retrospectively analyzed.The related risk factors,including gender,age,smoking history,drinking history,hypertension history,diabetes history,melanosis degree and so on,were collected.Establish a column chart model for predicting the risk of adenomatous polyps using R language,evaluate the model through C-index,calibration curve,and decision curve analysis(DCA),and validate the model internally using Bootstrap method.Results Gender,degree of melanosis,homocysteine,HbA1c,TSH,fecal occult blood,gallstones or polyps,HP infection were the independent influencing factors of adenomatous polyps in patients with melanosis of large intestine.The model had a good discrimination in predicting the risk of adenomatous polyps in patients with colorectal melanosis.Hosmer Lemeshow goodness of fit test showed that the P values of the training set and the validation set were 0.157 and 0.179,respectively(both＜0.05),indicating that the model fitted well.When the threshold probability of the training set and the validation level were both 0％to 100％,patients with melanosis of the colon may benefit from clinical intervention.Conclusion The risk model established by the above risk factors has good discrimination and good fit,which can provide reference for clinical decision-making.

Modern Interventional Diagnosis and Treatment in Gastroenterology.2024;29(2):158-162. doi:10.3969/j.issn.1672-2159.2024.02.008

Objective To clarify the expression levels of miR-934 and miR-1307 in serum of patients with esophageal squamous cell carcinoma(ESCC),and analyze the relationship between their expression and clinicopathological features and prognosis.Methods A total of 125 ESCC patients(ESCC group)who were admitted to our hospital from January 2018 to December 2019 were selected,and 100 healthy subjects(control group)were selected during the same period,the expression of miR-934 and miR-1307 in serum were detected by real-time fluorescence quantitative reverse transcription polymerase chain reaction(qRT-PCR).After 3 years of follow-up,the patients were divided into miR-934 low expression group(＜2.53)and miR-934 high expression group(≥2.53),miR-1307 low expression group(＜2.10)and miR-1307 high expression group(≥2.10),based on their mean values,the prognosis of patients with different expression of miR-934 and miR-1307 in serum was compared,and the related factors affecting the survival and prognosis of patients were analyzed by univariate and multivariate COX regression analysis.Results The relative expression levels of serum miR-934 and miR-1307 in ESCC group were 2.53±0.72 and 2.10±0.68 respectively,significantly higher than those in control group's 1.32±0.39 and 1.12±0.33(all P＜0.05).Serum miR-934 and miR-1307 were closely related to TNM stage,lymph node metastasis,tumor differentiation and distant metastasis in ESCC patients(all P＜0.05).The 3-year progression-free survival(PFS)in serum miR-934 and miR-1307 high expression group was lower than that in miR-934 and miR-1307 low expression group.Multivariate Cox regression analysis showed that,TNM stage Ⅲ～Ⅳ,high expression of miR-934 and high expression of miR-1307,low differentiation degree and distant metastasis were independent risk factors for PFS in ESCC patients(all P＜0.05).Conclusion Serum miR-934 and miR-1307 are abnormally highly express in ESCC patients,and their high expression is an independent risk factor for poor prognosis of ESCC patients,which is expected to be a marker for prognosis evaluation of ESCC.

Objective This study aims to explore the role of Insulin-like growth factor binding protein(IGFBP)7in the pathogenesis of nonalcoholic fatty liver disease(NAFLD).Methods A mouse model of NAFLD was established by feeding a high-fat diet and IGFBP7 was knocked out by injecting adeno-associated virus(AAV)-mediated short hairpin(sh)-IGFBP7 into the liver.The mice were randomly divided into 4 groups(n=6 per group):normal diet group(ND),high fat diet group(HFD),HFD empty carrier injection group(HFD/AAV-null),and HFD AAV-sh-IGFBP7 injection group(HFD/AAV-sh-IGFBP7).ND group was given normal diet for 12 weeks,HFD group,HFD/AAV-null group and HFD/AAV-sh-IGFBP7 group were given high fat diet for 4 weeks.HFD/AAV-sh-IGFBP7 group and HFD/AAV-null group were injected with 2 × 1011 genome copies of AAV-sh-IGFBP7 or AAV-null group,respectively,and then continued to be fed for 8 weeks.Body weight,liver wet weight and liver index of mice in each group were determined.Serum triglyceride(TG),total cholesterol(TC),alanine aminotransferase(ALT),aspartate aminotransferase(AST),free fatty acid(FFA),glycerol and liver TG of mice in each group were detected by biochemical analyzer.Real-time quantitative PCR and Western blot were used to detect IGFBP7 mRNA in each group.Protein expression levels and mRNA expression levels of sterol regulatory element binding protein 1c(SREBP-1c),fatty acid synthase(FASN),acetyl-CoA carboxylase1(ACC1)and stearoyl-CoA desaturase 1(SCD1)related to lipogenesis.Results Compared with ND group,body weight,liver wet weight,liver index and serum ALT,AST,FFA,TG,TC,glycerol and liver TG levels in HFD group were significantly increased,and the differences were statistically significant(P＜0.05),while body weight,liver wet weight,liver index and serum ALT,AST,and serum TG levels in HFD/AAV-sh-IGFBP7 group were significantly increased(P＜0.05).FFA,TG,TC,glycerol and liver TG levels increased less than those of HFD/AAV-null group,and the differences were statistically significant(P＜0.05).Compared with ND group,the expression levels of IGFBP7mRNA and protein in liver of mice in HFD group were increased,and the difference was statistically significant(P＜0.01).Compared with HFD/AAV-null group,the expression level of IGFBP7 protein in liver of HFD/AAV-sh-IGFBP7 group was significantly decreased,and the difference was statistically significant(P＜0.01).Compared with ND group,mRNA expression levels of SREBP-1c,FASN,ACC1 and SCD1 in liver tissues of mice in HFD group were significantly increased,with statistical significance(P＜0.01).Compared with HFD/AAV-null group,mRNA expression levels of SREBP-1c,FASN,ACC1 and SCD1 in HFD/AAV-sh-IGFBP7 group were decreased,and the difference was statistically significant(P＜0.01).Conclusion IGFBP7 is involved in hepatic steatosis during the development of NAFLD.Down-regulation of IGFBP7 can reduce the accumulation of lipid in the liver and has a protective effect on the pathogenesis of NAFLD,which may be a new drug for the treatment of NAFLD.
