ABSTRACT
Objective To study the correlation between individual gene polymorphisms of transforming growth factor (TGF)-β1 + 869 T/C,tumor necrosis factor-related apoptosis-inducing ligand (TRAIL) + 1525 G/A genes and nodular thyroid disease.Methods From September 2007 to December 2009,a total of 544 patients with nodular thyroid disease diagnosed in the Department of Endocrinology,The First Affiliated Hospital of Baotou Medical College,Inner Mongolia University of Science and Technology were selected,including 136 cases of nodular goiter patients (node group),132 cases of thyroid tumor (adenoma group),146 cases of Graves patients (GD group),and 130 cases of Hashimoto's thyroiditis (HT group).One hundred and thirty-five healthy subjects were enrolled as control group.Two milliliters of fasting venous blood of all subjects were collected.Polymorphisms of the TGF-β1 + 869 T/C and the TRAIL 1525 A/G genes were identified by the polymerase chain reaction-single strand conformation polymorphism (PCR-SSCP) and the restriction fragment length polymorphism (PCR-RFLP) methods.Results TGF-β1 + 869 T/C:The CC genotypes and C allele frequencies of nodular goiter group [47.0％(64/136),63.2％(172/ 272)] were significantly higher than those of normal control group [18.0％(22/135),45.2％ (122/270); x2 =30.76,17.79,all P ＜ 0.05].The genotypes and allele frequencies of adenoma group[42.4％ (56/132),59.1％ (156/264)] were significantly higher than those of the normal control group (x2 =24.40,10.34,all P ＜ 0.05).The risk of population carrying the C allele suffering from nodular goiter was 2.086 times of those carrying the T allele (OR =2.086; 95％ CI:1.480-2.943).The risk of population carrying the C allele suffering from adenoma was 1.752 times of those carrying the T allele (OR =1.752,95％ CI:1.244-2.469).TRAIL + 1525 G/A:the genotypes and allele frequencies of nodular goiter group [40.4％ (55/136),62.9％ (171/272)] were significantly higher than those of normal control group [12.0％ (16/135),48.5％ (131/270); x2 =9.176,11.307,all P ＜ 0.05].The genotypes and allele frequencies of adenoma group[53.3％ (70/132),73.1％ (193/264)] were significantly higher than those of the normal control group (x2 =9.806,33.82,all P ＜ 0.05).The risk of population carrying the G allele suffering from nodular goiter was 1.796 times of those carrying the A allele (OR =1.796,95％ CI:1.275-2.531).The risk of population carrying the G allele suffering from adenoma was 2.884 times of those carrying the A allele (OR =2.884,95％ CI:2.009-4.142).Conclusions TGF-β1 + 869 T/C and TRAIL + 1525 G/A gene polymorphisms may be related to the incidence of nodular thyroid diseases; G allele of TRAIL and C allele of TGF-β1 may be predisposing genes of patients with nodular goiter.
ABSTRACT
Objective To investigate the relationship between the apolipoprotein B (ApoB) gene Xba Ⅰ and EcoR Ⅰ polymorphisms and cholelithiasis in Han and Mongolian population in the Midwest Area of Inner Mongolia.Methods The clinical data of 100 patients with cholelithiasis and 115 healthy individuals at the First Affiliated Hospital of Medical College of Baotou from April to October in 2010 were collected.A case-control study which detected ApoB alleles of patients with cholelithiasis (cholelithiasis group) and healthy individuals (control group) in Han nationality and Mongolian nationality in the Midwest Area of Inner Mongolia was conducted by polymerase chain reaction-restriction fragment length polymorphism,which included Xba Ⅰ (X + X +,X + X-,X-X-,X +,X-) and EcoR Ⅰ (E + E +,E-E-,E + E-,E +,E-).The serum lipid (including triglyceride,total cholesterol,high density lipoprotein and low density lipoprotein) levels in different groups were detected.The count data and the measurement data were analyzed using the chi-square test and t test,respectively.Results Genotype X + X + was not found in the Han and Mongolian population,and Xba Ⅰ (X +) or EcoR Ⅰ (E-) alleles was not found in the Mongolian population.The levels of low density lipoprotein were (2.8 ± 0.9)mmol/L in the cholelithiasis group,which was significantly higher than (1.9 ± 0.8) mmol/L of the control group in the Han population (t =2.800,P ＜ 0.05).The levels of high density lipoprotein and low density lipoprotein were (1.7 ± 0.3) mmol/L and (3.5 ± 0.8) mmol/L of the cholelithiasis group,which were significantly higher than (1.2 ± 0.3) mmol/L and (2.8 ± 0.9) mmol/L of the control group in the Mongolian population (t =7.596,2.549,P ＜ 0.05).The levels of triglyceride,total cholesterol,high density lipoprotein and low density lipoprotein of the cholelithiasis group in the Mongolian population were (3.1 ± 1.6) mmol/L,(5.6 ± 1.0) mmol/L,(1.7 ± 0.3) mmol/L and (3.5 ± 0.8) mmol/L,which were significantly higher than (1.2 ± 0.6) mmol/L,(4.4 ± 1.2) mmol/L,(1.3 ± 0.3) mmol/L and (2.8 ± 0.9) mmol/L of the cholelithiasis group in the Han population (t =5.501,3.667,4.448,3.430,P ＜ 0.05).The levels of triglyceride,total cholesterol,low density lipoprotein were (2.6 ± 1.7) mmol/L,(5.1 ± 1.1) mmol/L and (2.8 ± 0.9) mmol/L of the control group in the Mongolian population,which were significantly higher than (1.3 ±0.7)mmol/L,(3.9 ±0.9) mmol/L and (1.9 ±0.8) mmol/L of the control group in the Han population (t =4.298,4.772,3.888,P ＜ 0.05),while the level of high density lipoprotein was significantly higher of the control group in the Han nationality than the control group in the Mongolian population (t =1.997,P ＜ 0.05).The levels of low density lipoprotein in patients with genotypes X + X-,X-X-of the cholelithiasis group in the Han population were (2.7 ± 0.1) mmol/L and (2.6 ± 1.0) mmol/L,and the levels of low density lipoprotein in patients with genoeypes E + E ±,E + E-/E-E-were (2.6 ± 1.0) mmol/L and (2.5±0.4)mmol/L,with no significant difference (t=0.225,0.124,P＞0.05).Conclusion In the Midwest area of Inner Mongolia,the Mongolian population might be more susceptible to cholelithiasis than the Han population.No relationship between the rare alleles X +,E-and the increase of blood lipids,which indicates that X + and E-of ApoB may not be a risk factor of cholelithiasis.
ABSTRACT
Objective To promote the level of early diagnosis and strengthen the understanding of pathogenesis, pathological staging and prognosis of primary gallbladder carcinoma (PGC). Methods The data of 679 patients with PGC treated in our hospital from 1956 to 1998 were retrospectively analyzed. Results The incidence of PGC has been increasing in recent years while the surgical management for the disease was not satisfactory. Upon diagnosis, most patients were with PGC in advanced stage. PGC was usually found among the aged woman patients. The female/male ratio was 3∶1. There was a close relationship between gallstone and PGC, for the gallstone was found in 60% of the patients with PGC. The diagnostic accordance rate before and after operations was low. Most cases of PGC were found unexpectedly during operation due to gallstone or acute cholecystitis. It was even worse that many patients with PGC missed the opportunity of diagnosis and treatment because doctors noticed the gallstone only. Pathological classification revealed that most cases of PGC were of adenocarcinoma. Development in imaging medicine might help a lot in finding early-stage cases and improving prognosis. Conclusions Strengthening the understanding of pathogenesis, pathological staging and prognosis of the disease and proper use of various examinations are the basic means of obtaining early diagnosis and improving the prognosis.
