RESUMEN
Objective To investigate the levels of serum CXC-chemokine ligand 16(CXCL16)and anti-neu-trophil cytoplasmic antibody(ANCA)in patients with allergic rhinitis and their clinical diagnostic value.Meth-ods A total of 84 patients with allergic rhinitis(allergic rhinitis group)treated in the hospital from January to December 2022 were selected as the study objects,and were divided into mild group(44 cases)and moderate and severe group(40 cases)according to the severity of their disease.Another 80 healthy subjects who had physical examination in the same period were selected as the control group.The levels of CXCL16 and ANCA in serum were determined by enzyme-linked immunosorbent assay.The correlation between serum CXCL16 and ANCA levels and inflammatory factors[interleukin(IL)-4,IL-9,IL-13]and immunoglobulin E(IgE)was analyzed by Pearson.The value of serum CXCL16 and ANCA levels in the diagnosis of moderate and severe allergic rhinitis was evaluated by receiver operating characteristic(ROC)curve.Results Compared with con-trol group,the levels of IL-4,IL-9,IL-13 and IgE in allergic rhinitis group were significantly increased,and the difference was statistically significant(P＜0.05).Compared with control group,serum CXCL16 and ANCA levels in allergic rhinitis group were significantly increased,and the differences were statistically significant(P＜0.05).The area under the curve(AUC)of serum CXCL16 and ANCA in patients with allergic rhinitis was 0.897 and 0.844,respectively.The AUC of combined diagnosis was 0.959,both of which were better than that of individual diagnosis(Z=2.164,3.474,P＜0.05),and the specificity was 93.75％.The sensitivity was 89.29％.The levels of serum CXCL16 and ANCA in patients with allergic rhinitis increased with the se-verity of the disease(P＜0.05).Pearson correlation analysis showed that serum CXCL16 and ANCA levels were positively correlated with IL-4,IL-9,IL-13 and IgE in patients with allergic rhinitis(P＜0.05).ROC curve analysis results showed that the AUC of the patients diagnosed with moderate and severe allergic rhini-tis by serum CXCL16 and ANCA was 0.862 and 0.832,respectively,and the AUC of the combined diagnosis of CXCL16 and ANCA was 0.949,both of which were better than those diagnosed separately(Z=1.981,2.378,P＜0.05),and the specificity was 90.91％.The sensitivity was 90.00％.Conclusion The levels of se-rum CXCL16 and ANCA in patients with allergic rhinitis increased significantly,and increased with the severi-ty of the patients'disease,both of which have certain value in the clinical diagnosis of allergic rhinitis.
RESUMEN
Objective:To investigate the serum levels of myonectin, corticostatin and Delta like ligand 4 (DLL4) in patients with type 2 diabetes mellitus (T2DM) diabetes retinopathy (DR) and their clinical significance.Methods:A prospective selection of 341 T2DM patients admitted to Beijing Hospital of Traditional Chinese Medicine, Huairou Hospital from May 2020 to March 2022 was conducted. The patients underwent fundus examination and were divided into a non DR group ( n=85 cases) and a DR group ( n=256 cases) based on DR diagnostic criteria. The DR group was divided into non proliferative and proliferative types according to the staging criteria in China′s DR clinical diagnosis and treatment guidelines, with 142 cases and 114 cases, respectively; 190 healthy individuals who underwent physical examinations in our hospital during the same period were selected as the control group. Enzyme linked immunosorbent assay was used to detect the levels of serum sarconectin, corticostatin, and DLL4 in three groups, collect patient data, and detect biochemical indicators. Logistic regression analysis was used to analyze the influencing factors of DR, and Pearson correlation analysis was used to investigate the relationship between serum sarconectin, corticostatin, DLL4, glucose and lipid metabolism, and insulin resistance; Logistic regression analysis was used to analyze the influencing factors of DR, and Pearson correlation analysis was used to investigate the relationship between serum sarconectin, corticostatin, DLL4, glucose and lipid metabolism, and insulin resistance; The receiver operating characteristic (ROC) curve was used to analyze the diagnostic value of serum sarconectin, corticostatin, and DLL4 in DR. Results:The levels of serum sarconectin and DLL4 in the DR group and non DR group were higher than those in the control group, while the levels of corticostatin were lower than those in the control group (all P<0.05); The levels of sarconectin and DLL4 in the DR group were higher than those in the non DR group, while the levels of corticostatin were lower than those in the non DR group (all P<0.05). The serum levels of sarconectin and DLL4 in proliferative DR patients were higher than those in non proliferative DR patients, while the levels of corticostatin were lower than those in non proliferative DR patients (all P<0.05). The duration of T2DM in the DR group was longer than that in the non DR group, with smoking and alcohol consumption, systolic blood pressure, fasting blood glucose, glycated hemoglobin, triglyceride and insulin resistance index (HOMA-IR) were higher than those in non DR group (all P<0.05). Logistic regression analysis showed that the course of T2DM, systolic blood pressure, smoking and alcohol consumption, glycated hemoglobin, triglycerides, myonectin, corticostatin and DLL4 were the influencing factors of DR (all P<0.05). Pearson correlation analysis results showed that serum sarconectin, DLL4, and fasting blood glucose, glycated hemoglobin, fasting insulin and HOMA-IR were positively correlated (all P<0.05), while cortisol was negatively correlated with fasting blood glucose, glycated hemoglobin and HOMA-IR (all P<0.05). The ROC analysis results showed that the area under the curve (AUC) for the diagnosis of DR was 0.691, 0.745, 0.749, and 0.861 for sarconectin, corticostatin, and DLL4 alone and in combination, respectively. The combined application had higher diagnostic value. Conclusions:Patients with T2DM complicated with DR have elevated levels of serum sarconectin and DLL4, while decreased levels of corticostatin, which are closely related to glucose and lipid metabolism and insulin resistance, and are influencing factors for the occurrence of DR. Combined detection of the three can improve the value of predicting DR.
RESUMEN
Objective To investigate the effect of laparoscopic radical resection of rectal cancer by reserving the left colon artery and root lymph node accurately according to different types of inferior mesenteric artery.Methods In this study,80 cases of rectal cancer patients diagnosed and treated from January 2019 to January 2022 were selected as the research objects.According to the envelope random grouping method,the above patients were randomly divided into observation group and control group,with 40 cases in each group.According to the intestinal mesenteric classification of patients,the observation group carried out precise low ligation operation,while the control group adopted traditional high ligation operation.The perioperative indexes,complications,gastrointestinal function,gastrin and motilin were compared between the two groups.Result There was no significant difference in operation time,intraoperative blood loss,exhaust time and lymph node positive rate between the two groups(P＞0.05),and the number of lymph node dissection in the observation group(24.27±5.92)was significantly higher than that in the control group(16.12±5.99),there was significant difference(P＜0.05).There was no significant difference in dysuria,anastomotic bleeding and anastomotic leakage between the two groups(P＞0.05).There was no significant difference between the recovery time of bowel sounds and the time of eating(P＞0.05).After operation,the gastrin and motilin water in the two groups decreased significantly,but the gastrin[(133.33±16.14)pg/ml]and motilin(318.33±24.11)pg/ml]in the observation group were significantly higher than that of the control group[(114.78±15.97)pg/ml,(287.44±23.09)pg/ml],the difference was statistically significant(P＜0.05).Conclusion Laparoscopic radical resection of rectal cancer according to the different types of inferior mesenteric artery accurately retain the left colon artery and root lymph node dissection,postoperative gastrointestinal function and lymph node dissection significantly improved,for the prognosis of patients with positive significance.
