Journal of China Medical University 2015;(3):247-251
Objective To compare differences in pathological grade,clinical classification and prognosis in patients with Henoch?Sch?nlen purpu?ra nephritis(HSPN)in each age group. Methods Totally 225 cases of patients diagnosed as HSPN and treated in the hospital were selected to ret?rospectively analyze their clinical manifestations,pathological classification and prognosis and compare the difference in pathological grade,clinical classification and prognosis by age. Results Of the concomitant symptoms of HSPN,the incidence rate of abdominal pain was the highest in pa?tients of school age. There was statistical significance in the incidence rate of gastrointestinal bleeding between each age group. Of the clinical mani?festations,proteinuria was positive correlated with the pathological type,and the difference was statistically significant(r=0.471,P<0.000 1). But there was no correlation between the count of urine red blood cells in the urine and the pathological type. There was difference in the pathological grade between each age group(H=19.194,P<0.000 1). The difference mainly showed in the pathological grade between adults,children of pre?school age and adolescents(Z=-2.702,P=0.001;Z=-3.675,P<0.000 1). There was difference in clinical classification between each age group (χ2=36.114,P<0.000 1). The difference mainly showed in clinical manifestations between adults,children of school age and adolescents(χ2=19.628,P<0.000 1;χ2=18.944,P<0.000 1). For both children and adults who had developed into chronic renal failure,the renal pathology of these patients was not significantly different. Conclusion Compared with adults,children have milder pathological types and clinical manifestations and well prognosis of HSPN,and the most important factor which affects the prognosis is pathological type and urine protein can reflect the serious?ness of pathological type.

Inflammation is involved in the pathogenesis of many vascular disorders. Hemodynamics cause the activation of inflammatory factors in the vascular wal , resulting in dysfunction of vascular endothelial cels and vascular smooth muscle cels, activating vascular wal inflammatory cascade. Inflammatory cels, especialy macrophage infiltration and secretion of enzymes gradualy weaken the vessel wal to form aneurysm, and even cause aneurysm rupture. Therefore, inflammation plays a key role in the formation and rupture of intracranial aneurysms.

Objective To investigate the diagnostic value of serum tumors M2 pyruvate kinase (TuM2-PK),carcino-embryonic antigen (CEA),CA199,CA724,CA125 and CA242 in colon cancer.Methods Serum levels of TuM2-PK,CEA,CA199,CA724,CA125 and CA242 in 231 patients with colon cancer,105 patients with colon benign lesion diseases and 166 normal controls were measured by the ELISA and electrochemiluminescence assays.The operation working characteristic curve (ROC) and the logistic regression-ROC were used to evaluate the diagnostic value of tumor markers for colon cancer individually and in combination.The models of logistic regression analysis and partial least-squares discriminant analysis (PLS-DA) were established to diagnose patients with colon cancer based on the optimal panel of serum tumor markers.Resalts Concentrations of serum TuM2-PK,CEA,CA199,CA125 and CA724 in the colon cancer group are higher than those in the colon benign diseases group and the normal controls (P<0.05).The area under the operation working characteristic curve (AUC) of CA199 is the highest 0.79 [95% confidence interval (95%CI),0.75-0.83] at the cutoff value of 69.5 U/L with 64.1% of sensitivity and 89.7% of specificity.The AUC of combined serum tumor markers based on logistic regression analysis is higher than those in individuals,of which serum (CEA+ CA199+TuM2-PK) is the optimal [AUC=0.89,95% confidence interval(95%CI),0.86-0.92].The diagnostic accuracy of logistic analysis and PLS-DA model for colon cancer is 82.7% and 77.5%,and for colon cancer is 93.7% and 95.6%,respectively.Conclusion The combination of serum tumor markers CEA,CA199 and TuM2-PK is more suitable as a diagnostic model for the screening of colon cancer.

Objective This study assesses the influence of rizatriptan on calcitonin gene-related peptide (CGRP),proenkephalin (PENK) and cholecystokinin (CCK) mRNA expressions in the trigeminal ganglia of a rat migraine model and investigates the possible mechanisms by which triptans treat migraine.Methods A total of 24 rats were randomly divided into four groups:normal control group (A),migraine model group(B),rizatriptan control group (C) and rizatriptan treatment group(D).Groups C and D were intragastrically perfused with rizatriptan,1 mg/kg per day.After 7 days,nitroglycerin was subcutaneously injected into the buttocks of the groups B and D to induce migraine.Two hours after nitroglycerin injection,the trigeminal ganglia was isolated.CGRP,PENK and CCK mRNA expressions in the trigeminal ganglia were determined using SYBR Green Ⅰ real-time quantitative PCR.Results The copy number of CGRP mRNA (× 107) in 200 ng total RNA of each group was 0.05 ±0.01,1.30 ±0.52,0.23 ±0.12,0.43 ±0.33 ; The copy number of PENK mRNA (× 103) in 200 ng total RNA of each group was 3.30 ± 1.65,0.34 ±0.14,3.91 ± 2.44,0.71 ± 0.13.The copy number of CGRP mRNA in the trigeminal ganglia of group B was significantly higher than that of group A (q =7.854,P < 0.05) ; CGRP mRNA expressions were significantly lower in the trigeminal ganglia of rats in group D compared with group B (q =5.458,P <0.05).Compared with group A,PENK mRNA expressions in the trigeminal ganglia of rats were significantly lower in group B (q =4.478,P < 0.05).PENK mRNA expressions were significantly higher in trigeminal ganglia of rats in group C compared with group D (q =4.838,P < 0.05).CCK mRNA expression in trigeminal ganglia of rats was similar among groups.Conelusions Rizatriptan can decrease the expressions of CGRP in the trigeminal ganglia of the migraine rats and exhibits neurogenic inflammation triggered by CGRP.PENK expressions decrease in the trigeminal ganglia of the migraine rats,weaken the analgesic effects of enkephalin.
