RESUMO

【Objective】 To investigate the influence of matrine (MT) on the balance of T helper cell 17 (Th17)/regulatory T cells (Treg) in rats with inflammatory bowel disease by regulating interleukin-6 (IL-6)/signal transducer and activator of transcription 3 (STAT3)/nuclear transcription factor-κB (NF-κB) pathway. 【Methods】 SD rats were grouped into control check group (CK group), model group, low-dose MT group (MT-L group, 50 mg/kg), medium-dose MT group (MT-M group, 100 mg/kg), high-dose MT group (MT-H group, 200 mg/kg), mesalazine group (MSLM group, 0.42 g/kg), and MT-H+rIL-6 (IL-6 activator) group (200 mg/kg+0.05 mg/kg) according to the random number table method, with 18 in each group. Except for the CK group, the rats in other groups all received with 5% trinitrobenzenesulfonic acid (20 mg/kg) buffer solution mixed with 50% ethanol at a ratio of 1∶1 and then enema to construct a rat model of inflammatory bowel disease. After the successful modeling, they were treated with drug administration once a day for 7 weeks. The body weight of rats was measured at 1, 3, 5, and 7 weeks of administration; the changes of colon length of rats in each group were compared; HE staining was used to detect the pathological damage of rat colon tissue; the levels of tumor necrosis factor-α (TNF-α), interleukin (IL)-17 and IL-10 in serum of rats were detected by ELISA; the proportions of Th17 and Treg cells in peripheral blood of rats were detected by flow cytometry; Western blottingt was performed to detect the protein expression of retinoic acid-related orphan receptor γt (RORγt), forkhead box protein P3 (Foxp3), IL-6, p-STAT3, and p-NF-κB p65 in rat colon tissue. 【Results】 Compared with the CK group, the colon tissue of the model group was severely damaged by pathology, and the body weight (at 3, 5, and 7 weeks), the level of IL-10, the proportion of Treg cell, and the expression of Foxp3 protein were decreased, the colon length shortened, the levels of TNF-α, IL-17, the proportions of Th17 cell, Th17/Treg ratio, and the protein expression of RORγt, IL-6, p-STAT3, and p-NF-κB p65 increased (P<0.05). Compared with the model group, the corresponding indicators of the MT-L group, MT-M group, MT-H group, and MSLM group had the opposite trends (P<0.05); rIL-6 attenuated the promoting effect of high-dose MT on Th17/Treg balance in inflammatory bowel disease rats. 【Conclusion】 MT may promote Th17/Treg balance in inflammatory bowel disease rats by inhibiting IL-6/STAT3/NF-κB signaling pathway.

RESUMO

Objective To investigate the auxiliary diagnostic value of combined detection serum lipoprotein-associated phospholipase A2 (LP-PLA2) and small and dense low-density lipoprotein (sd-LDL) in atherosclerosis.Methods The subjects were divided into experimental group and control group by random block design from May 2017 to January 2018,in the First Affiliated Yijishan Hospital of Anhui Wannan Medical College.The experimental group selected 125 AS patients with clinical diagnosis and confirmed by angiography,and 55 healthy subjects were chosen as the normal control group at the same time.Serum samples were collected within 24 hours after admission,and the level of LP-PLA2,sdLDL-C,low density lipoprotein cholesterol (LDL-C),triglyceride (TG),total cholesterol (TC) and high-sensitive C reactive protein (hs-CRP) were unified detection.The t test,single factor variance analysis and Mann-Whitney U and multivariate logistic regression analysis were used to analyze the data.Results LP-PLA2,sd-LDL,LDL,TC,TG and hs-CRP of the AS group were all higher than those of the healthy control group (Z=5.279,6.663,6.012,5.863,5.508 and 2.845,respectively,P<0.05).Logistic regression analysis showed that serum LP-PLA2,sd-LDL and hs-CRP level was an independent risk factor for predicting atherosclerosis (OR=1.008,P=0.003;OR=8.282,P=0.012;OR=1.158,P=0.009).The sensitivity of LP-PLA2,sd-LDL,LDL-C,TC,TG,hs-CRP to AS was detected separately (57.6%,73.6%,85.6%,83.2%,76.8%,80.0%),and the specificity was (89.1%,78.2%,67.3%,69.1%,74.5%,52.7%).The ROC curve showed that the diagnostic efficacy of LP-PLA2 and sd-LDL combined detection was 0.854,higher than sd-LDL,LDL-C,TC,TG,LP-PLA2 and hs-CRP (0.811,0.782,0.775,0.758,0.747 and 0.633,respectively).In addition,the levels of both increased with the aggravation of arteriosclerotic lesion(x2=7.954,P=0.019;x2=11.44,P=0.003).The levels of LP-PLA2 and sd-LDL in patients with AS were not significantly different between different lesions (x2=8.042,P=0.09;x2=5.952,P=0.203).There was no significant difference between serum LP-PLA2 and sd-LDL level and sex,age,smoking,hypertension and diabetes (Z1=0.398,0.719,0.619,0.098 and 1.338 respectively,Z2=0.942,0.027,0.894,0.375,0.783,respectively,both P1 and P2 were>0.05).Conclusions sd-LDL combined with LP-PLA2 has high sensitivity and specificity in the prediction of AS,which makes up for the deficiency of individual detection;sd-LDL and LP-PLA2 serum level has nothing to do with the lesion and has a positive correlation with the degree of lesions.It is not easily affected by other risk factors and can be used as a risk factor for predicting the occurrence of AS.
