In this paper are discussed the relationships between the infiltrating distances and the pathological types of gastric cancer by measuring the excised specimens of middle and dvanced stages in 50 cases.It is confirmed that the infiltrating distances vary according to the pathohistolog-ical types. The tubular adenocarcinoma may be divided into two subtypes: the large tubular adenocarcinoma and the small tubular adenocarcinoma. In all pathohistological types of gastric cancer the undifferentiated carcinoma, "signet-ring" cell carcinoma and tubular adenocarcinoma infiltrated farther, and the papillary adenocarcinoma and the small tubular adenocarcinoma into a less.The infiltraing type and gastric sinus carcinoma have tendency to infiltrate farther which can be observed with naked eye.These results may offered some assistance in the surgical treatment of gastric cancer.

Objective To establish and investigate C57 BL/6 mice model of radiation induced heart injury and ser-um marker. Methods Twenty eight female C57BL/6 mice were randomly divided into 3 groups:normal group (n=4 ) , 18 Gy radiation therapy group ( n=12 ) , 25 Gy radiation therapy group ( n=12 ) . The mice were weighed every week. Respectively, 0, 8 and 16 weeks after irradiation, the pathological changes of myocardial tissue were observed by hemetoxylin-eosin( HE) staining and made pathological score. Inferior vena cava blood was collected to take cardiac troponin I ( cTnI) test. Results Compared with the normal group,the weight of radiation group went down first then went up slowly. The myocardial tissue from mice had obvious histopathological changes. Acute in-flammation was the main change in the early days. At the late stage, progressive fibrosis was the main characteris-tic. With the increase of the dose, the inflammatory reaction and fibrosis degree had aggravated, pathological chan-ges had occurred earlier. cTnI showed a trend of higher performance over time, and had a correlation with patholo-gy. Conclusion We successfully established radiation induced myocaridal injury model. As a noninvasive serum marker, cTnI can be used as the evaluation standard of radiation induced myocardial injury animal model.

Along with the continuous publication of a series of large-scale clinical trials results,endovascular thrombolytic therapy (or combined with intravenous thrombolysis) has been recommended as the treatment of first choice for acute ischemic stroke caused by large intracranial artery occlusion.Nevertheless,there are a variety of factors that may affect the clinical outcome of endovascular recanalization procedure.This article aims to make a comprehensive review about the factors that may affect the prognosis of patients with acute ischemic stroke who are receiving endovascular treatment.

Objective To screen the differentially expressed proteins of blood stasis blocking tendon and vessel syndrome and liver-kidney deficiency syndrome of the steroid-induced osteonecrosis of the femoral head ( SONFH) by proteomic technology, so as to supply evidence for Chinese medical syndrome classification. Methods The serum was taken separately from 10 patients with blood stasis blocking tendon and vessel syndrome, 10 patients with liver-kidney deficiency syndrome and 10 healthy volunteers. The two dimensional electrophoresis combined with mass spectrometric method was applied to screen and identify the differentially expressed proteins, and then the obtained protein candidates were verified by Western blotting method. Results Seven proteins were identified from differentially expressed protein spots, including hemoglobin subunit delta, actin, complement C4, antithrombin-Ⅲ, apolipoprotein A-IV, leucine-rich alpha-2 glycoprotein and serum amyloid A-2 protein. We found that antithrombin-Ⅲ and serum amyloid A-2 protein had specific expression in the SONFH patients with blood stasis blocking tendon and vessel, and complement C4 and leucine-rich alpha-2-glycoprotein had specific expression in the SONFH patients with liver-kidney deficiency syndrome. The results of Western blot method showed that the expression levels of complement C4 and antithrombin-Ⅲ were down-regulated in SONFH patients ( P<0.05 compared with the healthy volunteers) , the down-regulation of complement C4 was more obvious in SONFH patients with liver-kidney deficiency syndrome (P<0.05) and the down-regulation of antithrombin-Ⅲ was more obvious in the patients with blood stasis blocking tendon and vessel (P<0.05), the results being accorded with those of proteomic detection. Conclusion Antithrombin-Ⅲand serum amyloid A-2 protein may be the specific serum protein markers of SONFH patients with blood stasis blocking tendon and vessel syndrome, and complement C4 and leucine-rich alpha-2-glycoprotein may be the specific serum protein markers of SONFH patients with liver-kidney deficiency syndrome.

Objective: To investigate the relationship between rs4373814 polymorphisms of calcium channel (CACNB2) gene and the susceptibility of essential hypertension (EH) occurrence in Han population at northeastern area of China. Methods: A case-control study in Han population at northeastern of China was carried out and the research included 1998 participants as 2 groups: EH group,n=1006 patients treated in our hospital, and Control group,n=992 subjects with normal blood pressure from physical examination. The rs4373814 polymorphisms were examined by Snapshot technique and the statistical analysis was performed by SPSS 19.0 software. Results: The rs4373814 risk allele C frequency of CACNB2 gene was signiifcantly different between EH group and Control group,P=0.039, OR=1.068, 95% CI (1.004-1.137). Logistic regression analysis showed that with adjusted gender, age, BMI, smoking, drinking, in dominant model, the genotype rs4373814 carring CC + GC/GG obviously increased the risk of EH occurrence,P=0.037, OR=1.260, 95% CI (1.013-1.567). Conclusion: The rs4373814 polymorphisms of CACNB2 gene are related to the susceptibility of EH occurrence in Han population at northeastern area of China.

Objective:To investigate the effect of thrombus burden on the clinical outcome of endovascular recanalization in large vessel occlusive stroke.Methods:Patients with acute anterior circulation occlusion who underwent endovascular treatment within 24 hours after onset in Zhengzhou University People′s Hospital from January 2018 to December 2019 were retrospectively collected. According to the clot burden score (CBS) of DSA, total objectives were divided into CBS≥6 group (24 cases) and CBS<6 group (38 cases). Clinical data of the two groups were collected and the modified Rankin scale (mRS) was used to evaluate the clinical outcome at 90 days after surgery. Independent sample t-test, Wilcoxon rank sum test and χ 2 test were used to compare the clinical data between the two groups. Independent risk factors affecting the clinical outcome were analyzed by binary logistic regression. Results:There were no statistically significant differences in basic demographic data, stroke risk factors and other factors between the CBS≥6 group and CBS<6 group ( P>0.05).The proportion of using tirofiban after surgery in the CBS≥6 group (63.2%, 24/38) was lower than that in the CBS<6 group (87.5%, 21/24) (χ2=4.380, P=0.044). The discharge NIHSS score of the CBS≥6 group was [5.0 (3.3, 7.8) points] lower than CBS<6 group [8.5 (1.8, 14.5) points] ( Z=5.221, P=0.022). The proportion of postoperative mRS 0-2 was (91.7%, 22/24) in the CBS≥6 group higher than CBS<6 group(39.5%, 15/38) (χ2=20.486, P=0.001), there were no statistically significant differences between the two groups ( P<0.05). The results of binary logistics regression analysis showed the CBS groups (OR=0.042, 95%CI 0.007-0.244 , P=0.001) was an independent risk factor affecting good outcome. Subgroup analysis of whether tirofiban was used or not showed there was no statistically significant difference in clinical prognosis between the two groups ( P>0.05). Conclusions:The clinical outcome of CBS≥6 group is significantly better than that of CBS<6 group, and patients with small thrombus burden are more likely to get a good clinical outcome of 90 days.

Mechanical thrombectomy can improve the clinical outcome of patients with acute anterior circulation larger vessel occlusive stroke.However,a remarkable proportion of patients,even they have achieved a successful recanalization,still develop adverse outcomes,such as futile recanalization(FR).According to relevant literature reports,there are many factors that can affect futile recanalization.In this paper,a series of factors such as age,recanalization time,infarct volume,baseline severity,blood pressure that may affect futile recanalization of mechanical thrombectomy in patients with inanterior circulation large vessel occlusion will be comprehensively described and analyzed.(J Intervent Radiol,2024,33:321-324)

Objective:To explore the characteristics of high-density sign of flat-panel CT (FDCT) after endovascular treatment in patients with acute ischemic stroke (AIS) in the anterior circulation of large vessels and their relation with hemorrhagic transformation.Methods:Seventy-eight patients with AIS in the anterior circulation of large vessels accepted endovascular treatment in our hospital from March 2018 to June 2019 were chosen in our study. All patients underwent FDCT, and they were grouped according to the presence of local high-density sign and occurrence of hemorrhagic transformation. The baseline and clinical data of patients from high-density sign group and non-high-density sign group, and from hemorrhagic transformation group and non-hemorrhagic transformation group were compared and analyzed. The correlation between high-density sign and hemorrhagic transformation was analyzed. The morphological characteristics and distribution of FDCT high-density sign in patients from high-density sign group were analyzed, and univariate and multivariate Logistic regression analyses were used to screen the influencing factors for post-operative hemorrhagic transformation in patients from the high-density sign group.Results:(1) The incidence of high-density sign in these patients after endovascular treatment was 41.0% (32/78); as compared with patients in the non-high-density sign group, patients in the high-density sign group had significantly higher rate of hemorrhagic transformation (6.5% vs. 53.1%, P<0.05) and significantly higher 3-month modified Rankin scale (mRS) scores (2.0 [1.0, 3.0] vs. 3.9 [3.0, 5.3], P<0.05). (2) The incidence of hemorrhagic transformation after endovascular treatment was 25.6% (20/78); as compared with those in the non-hemorrhagic transformation group, patients in the hemorrhage transformation group had statistically higher incidence of high-density sign in FDCT (31% vs. 70%, P<0.05); multivariate Logistic regression analysis showed that FDCT high density sign was an independent risk factor for hemorrhage transformation after endovascular treatment ( OR=1.823, 95%CI: 1.125-2.358, P=0.000). (3) In the 32 patients with FDCT high-density sign, 4 (12.5%), 13 (40.6%) and 7 (21.9%) had high-density sign in the cortex and subcortex, basal ganglia, and subarachnoid space, whose hemorrhagic transformation incidences were 75% (3/4), 53.8% (7/13), and 57.1% (4/7), respectively, and mean 3-month mRS scores were 4.5, 3.0 and 4.0, respectively; another 8 patients (25%) had endovascular FDCT high-density sign, whose hemorrhagic transformation incidence was 87.5% (7/8), and 3-month mRS scores were ≥4. (4) Multivariate Logistic regression analysis showed that the vascular opening time ≤6 h was a protective factor for hemorrhage transformation in patients with FDCT high-density sign ( OR=0.687, 95%CI: 0.193-0.936, P=0.044). Conclusions:In patients with AIS in the anterior circulation of large vessels accepted endovascular treatment, FDCT high-density sign indicates high risk of hemorrhage transformation and poor prognosis, especially in patients having high-density sign in the cerebral cortex, subcortical area and intravascular area. Minimizing the vascular opening time may reduce the risk of hemorrhagic transformation in patients with FDCT high-density sign.

OBJECTIVETo investigate the association between polymorphism of ATP2B1 gene, its interaction with smoking and susceptibility of essential hypertension.

METHODSA case-control study was conducted to elucidate the role of ATP2B1 gene variants related to the risk of essential hypertension. Genomic DNA was extracted from peripheral blood leukocytes, using the QIAamp DNA Mini Kit (QIAGEN,Germany). Two SNPs, - rs17249754 and rs6253, were examined on 1 280 patients and 1 010 healthy controls, using a Snapshot method. Statistical analyses were performed with SPSS Windows software (version 19.0;SPSS, Chicago, IL).

RESULTSA significant difference was found in rs17249754 allele frequency between cases and controls (OR = 1.223, 95%CI: 1.083-1.381, P = 0.001). After adjustment for age, sex, BMI, smoking and drinking, the difference was still statistically significant (OR = 1.212, 95%CI:1.070-1.373, P = 0.003). In addition, data from genotype distribution analysis under different models showed that appeared significant associations between ATP2B1 gene polymorphism and essential hypertension (additive model OR = 1.469, 95%CI: 1.121-1.925, P = 0.005; dominant model OR = 1.324, 95%CI:1.029-1.704, P = 0.029;recessive model OR = 1.123, 95%CI:1.031-1.223, P = 0.008). In this study, the proportion of smokers in cases was significantly higher than that in controls (P = 0.005), but no associations between rs17249754-smoking interaction and essential hypertension were found after the adjustment for gender, age, BMI and alcohol consumption (OR = 1.024, 95% CI:0.614-1.707).

CONCLUSIONOur research findings showed that the polymorphism of ATP2B1 gene rs17249754 was significantly associated with the incidence of essential hypertension in Han population of northeastern China. However, the interaction between rs17249754 and smoking did not seem to have contributed to the occurrence of the essential hypertension.
