Objective To investigate the clinical characteristics and traditional Chinese medicine(TCM)syndrome types of colorectal polyp(CP)and to explore their correlation with hyperlipidemia and other related risk factors.Methods From January 2022 to December 2023,174 patients with CP(polyp group)and 87 patients without intestinal abnormalities(non-polyp group)who underwent colonoscopy or treatment at the Endoscopy Center of Dongguan Hospital of Guangzhou University of Chinese Medicine were selected.Their data of medical records were collected,including gender,age,body mass index(BMI),history of diabetes mellitus,history of hypertension,blood lipid indicators[total cholesterol(TC),triglycerides(TG),low-density lipoprotein cholesterol(LDL-C),high-density lipoprotein cholesterol(HDL-C),and arteriosclerosis index(AI)],the presence of fatty liver or not,and the foci,number,size,and pathological types of polyps.Moreover,TCM syndrome differentiation of patients in the polyp group was carried out,and then the clinical characteristics and TCM syndrome types of CP as well as their correlation with hyperlipidemia were statistically analyzed.Results(1)The age group of 41-60 years old accounted for a higher percentage in patients of the polyp group and non-polyp group,59.8％in the polyp group and 49.4％in the non-polyp group,and the comparison of ages between the two groups showed statistically significant difference(P＜0.05).(2)The polyp foci of CP were mostly located in the left colon,accounting for 63.2％;single polyp was common,accounting for 69.0％;the size of polyps was usually 1-10 mm,accounting for 90.2％;the polyps were predominated by non-adenomatous polyps,accounting for 51.1％.(3)In the polyp group,spleen deficiency and dampness retention syndrome was the predominated syndrome type,accounting for 44.8％,and then followed by syndrome of damp-heat in large intestine,which accounted for 30.5％.(4)Comparison of the distribution of BMI and history of diabetes mellitus among various TCM syndrome types showed statistically significant differences(P＜0.05),while no statistically significant differences were presented in the comparison of gender,age,history of hypertension,and history of fatty liver,as well as the polyp foci,number,size,and pathological types among patients with various TCM syndrome types(P＞0.05).(5)The percentage of complication of hyperlipidemia in the polyp group was significantly higher than that in the non-polyp group,and the difference was statistically significant(P＜0.01).The levels of TC,TG,LDL-C,and Al in the polyp group were significantly higher than those in the non-polyp group,the differences being statistically significant(P＜0.05 or P＜0.01).However,the difference of the HDL-C level between the two groups was not statistically significant(P＞0.05).(6)Comparison of TC and LDL-C levels among the patients with different polyp foci and LDL-C level among the patients with various TCM syndrome types showed statistically significant differences(P＜0.05 or P＜0.01),while no statistically significant differences of blood lipid indicators were presented among the patients with various foci,number,sizes,and pathological types of the polyp and among the patients with various TCM syndrome types(P＞0.05).Conclusion Age is a risk factor for CP.CP patients are usually differentiated as the syndrome of spleen deficiency and dampness retention and the syndrome of damp-heat in large intestine,and the distribution of TCM syndrome types exert a certain correlation with BMI and history of diabetes mellitus.Hyperlipidemia is also a risk factor for the onset of CP,and abnormal levels of TC,TG,LDL-C,and Al exert certain correlation with the occurrence of polyps.TC and LDL-C have a certain correlation with the polyp foci,and LDL-C may also be related to the distribution of TCM syndrome types.

Objective To explore the clinical significance of serum ProGRP in diagnosis of SCLC.Methods Serum ProGRP were detected in twenty-three SCLC patients,forty NSCLC patients and forty-three patients with benign pulmonary disease whose were definite diagnosis collected from April 15,2016 to July 19,2016,and a contemporary cohort of 40 healthy controls were while recruited.Results The levels of ProGRP in SCLC group were significantly higher than those in NSCLC group,benign pulmonary disease group and healthy control group(P <0.05).The levels of ProGRP in extensive disease group were significantly higher than those in 1imited disease group(P <0.05).There was no significant difference in the positive rates of ProGRP between the sex group and age group (P > 0.05 ).The boundary value of diagnosis of SCLC through ProGRP identified through ROC curve was 65.66 ng/L.The sensitivity and specificity of the ProGRP for the diagnosis of SCLC were respectively 90.9% and 89.9%.Conclu-sion Serum ProGRP can be use as a sensitive and specific index for diagnosis of SCLC,and the level of ProGRP can also be used for the clinical staging of SCLC.
