Background:In recent years,the incidence and mortality of colorectal carcinoma have been increasing rapidly. Diagnosing and treating cancer at gene level have become a new effective approach. Aims:To investigate the expression of S-phase kinase-associated protein 2(Skp2)and its relationship with vascular endothelial growth factor(VEGF)and tumor microvessel density(MVD)in colorectal carcinoma. Methods:Thirty-five colorectal carcinoma patients from March 2014 to March 2015 at People’s Hospital of Hubei University of Medicine were enrolled. Fifteen para-cancerous tissue samples were served as controls. The expressions of Skp2,VEGF and MVD value were determined by immunohistochemical SP, and their relationships with clinicopathological characteristics were analyzed. Results:The expression of Skp2 in colorectal carcinoma was significantly higher than that in para-cancerous tissue( P = 0. 000),and was correlated with tumor differentiation and lymph node metastasis(P < 0. 05),but not with gender,age and TNM stage(P > 0. 05). Expression of VEGF and MVD value were significantly higher than those in para-cancerous tissue(P = 0. 019,P = 0. 002),and were correlated with lymph node metastasis and TNM stage(P < 0. 05). Expression of Skp2 was positively correlated with the expression of VEGF and MVD value in colorectal carcinoma( r = 0. 569,P = 0. 000;r = 0. 481,P = 0. 017 ). Conclusions:The abnormal high expression of Skp2 is involved in the angiogenesis of colorectal carcinoma. Skp2,VEGF expressions and MVD value may be served as important markers for malignancy degree of colorectal carcinoma.

Objective Ankylosing spondylitis (AS) can affect both the lumbar zygapophyseal joint and the centrum .This study was to compare multislice spiral CT ( MSCT) and MRI in the diagnosis of zygapophyseal joint lesions in AS patients and assess the role of zygapophyseal joint lesions in the early diagnosis of AS . Methods We retrospectively analyzed the lumbar imaging data of 41 male patients with AS .Forty-one male AS patients underwent MSCT , 18 receiving normal MRI , and the other 23 diffusion weighted imaging (DWI) and CE-T1WI-STIR in addition.Using Fisher′s Exact Test, we compared MSCT and MRI in their detection rates of a-pophyseal joint lesions and positive changes in the zygapophyseal joint and lumbar centrum .Then we analyzed the relation between the zygapophyseal joint lesions and the disease duration . Results The detection rates of zygapophyseal joint and centrum lesions were 90.2%and 58.5%on MSCT (P>0.05), and 80.5%and 46.3%on MRI (P>0.05), respectively.MSCT and MRI exhibited sig-nificant differences in the detection rate of centrum lesions (P<0.05) but not in that of zygapophyseal joint lesions (P>0.05). These lesions could appear within 1 year after the onset of AS or ahead of vertebral changes . Conclusion Both MSCT and MRI can manifest zygapophyseal joint lesions , which may develop in the lumbar spine at the early stage of AS , ahead of centrum lesions .This is important for the early diagnosis of AS .

PurposeTo investigate the physical characteristics of the lumbar bone marrow fat content by analyzing the correlation of the lumbar bone marrow fat content with age, gender, body mass index (BMI) and waist circumference. It may be helpful to deepen the understanding the occurrence regularity of osteoporosis. Materials and Methods A total of 144 subjects were recruited including both healthy volunteers and the patients with chronic low back pain. The height, weight and waist circumference were measured, and the body mass index was calculated. All the subjects took spectroscopy sequence at the third lumber vertebra with single-voxel point resolved spectroscopy (PRESS) method. Lipid (1.3 ppm) to water (4.67 ppm) ratio (LWR) and lipid fractions (FF%) were measured. LWR and FF% of L3 were compared among the patients with different gender, age, BMI and waist circumference. The correlation of LWR and FF% of L3 and age were analyzed.Results The LWR and FF% of L3 showed no signiifcant difference between the male and female (t=-0.267 and-0.993,P>0.05). There was statistical difference of LWR and FF% among the different age groups (F=3.723 and 5.478,P<0.05). LWR and FF% of female in 61-70 year-old group showed signiifcant higher than that in 20-30, 31-40, 41-50 and 51-60 year-old group (P<0.05). FF% of L3 in 20-30 year-old female group showed signiifcant lower than that in >70 year-old group (P<0.05). LWR of L3 for both male and female in 60-70 year-old group also showed signiifcant higher than that in 20-30, 31-40, 41-50 and 51-60 year-old group (P<0.05). FF% for both male and female in 20-30 year-old group showed signiifcant lower than that in 31-40, 41-50, 51-60, 61-70 and>70 year-old group (P<0.05). FF% of 61-70 year-old group was signiifcant different from that in 31-40, 41-50, 51-60 year-old group (P<0.05). The LWR and FF% of L3 showed no signiifcant difference between the different BMI groups and waist circumference groups (P>0.05). Age was positive correlated with FF% of L3 (r=0.321,P<0.05).Conclusion The lumbar bone marrow fat content is correlated with age, but is not correlated with gender, BMI and waist circumference.

Objective To compare the value of assessment with DWI and contrast-enhanced MRI (CE-MRI) in activity of sacroiliitis of patients with ankylosing spondylitis(AS).Methods Ninety-six patients conforming to modified New York criteria were prospectively collectedas the AS group, and twenty-one healthy volunteers were enrolled into the control group. According to the Bath AS disease activity index (BASDAI), erythrocyte sedimentation rate and C-reaction protein, AS patients were divided into the active AS group (n=60) and the chronic AS group (n=36) . All subjects were performed with conventional MRI, DWI and CE-MRI of bilateral sacroiliac joints. The MRI manifestations were reviewed and the ADC values and signal intensity enhancement rate (ΔSI) were measured.ANOVA was performed for the comparison ofΔSI and ADC values among active AS group, chronic AS group and control group with BASDAI and lab test results as the gold standards. ROC was analyzed with ΔSI and ADC values for activity of AS and paired
samples t test was obtained to comparethe areas under the ROC ofΔSI and ADC values.Results Among 96 cases of AS patients, MRI of sacroiliac jointsshowed that 62 cases had subchondral bone edema (57 cases of active group, 5 cases of chronic group), that 11 cases had bone surface erosion(4 cases of active group, 7 cases of chronic group), that 15 cases had bone sclerosis(6 cases of active group, 9 cases of chronic group) and that 58 cases had fat deposition on the sacroiliac joints (27 cases of active group, 31 cases of chronic group). The ΔSI values of the active group, the chronic group and control group were respectively (2.51 ± 1.69)%,(1.19 ± 0.67)%and(0.75 ± 0.21)%, and the ADCvalues were(1.33 ± 0.33)× 10-3,(1.00 ± 0.43)× 10-3 and(0.38±0.13)×10-3mm2/s. There were significant differences forΔSI and ADC values among three groups (F=18.375, 16.366. P<0.01), and statistical significance ofΔSI and ADC values were found between every two groups of three(P< 0.05).The area under the ROC between ΔSI and ADC to determine activity of AS patients were respectively 0.814 and 0.730, which had nostatistical significance(t=1.632, P=0.103). The sensitivity and specificity to determine activity of AS patients byΔSI=1.44%were 81.67%and 80.00%.The sensitivity and specificity to determine activity of AS patients by ADC=1.15 × 10-3/mm2 were 76.67% and 71.43%.Conclusion DWI and CE-MRI performed equally in detecting activity of AS patients.

OBJECTIVETo evaluate the diagnostic value of pelvis bone marrow fat depositions (BMFD) displayed by magnetic resonance imaging (MRI) in patients with ankylosing spondylitis (AS).

METHODSEighty-eight subjects undergoing pelvic MRI examinations were enrolled in this study, including 44 with clinically confirmed AS (39 male and 5 female patients with a mean age of 26.41∓8.09 years) and 44 control subjects without AS (37 male and 7 female subjects with a mean age of 29.32∓7.31 years). The incidence of BMFD in the bilateral sacroiliac (SI) joints and acetabulum were compared between the two groups. The distribution features of BMFD of the periarticular cancellous bone marrow in the pelvis and in other regions of the pelvis were analyzed for the AS patients, and the incidence of BMFD was determined in different stages of sacroiliitis and hip arthritis.

RESULTSThe incidence of BMFD in the SI joints and acetabulum was significantly higher in the AS patients than in the control subjects (P<0.01); The incidence of BMFD was significantly higher in the periarticular cancellous bone marrow than in the other positions of pelvis (P<0.01). The incidence of BMFD ranged from 40.0% to 45.9% in early stages of sacroiliitis, significantly lower than the incidence in later stages (58.3%-73.1%, P<0.01); the incidence showed no difference between different stages of hip arthritis (P>0.01).

CONCLUSIONSAS patients have a higher incidence of BMFD in the pelvis than control subjects. BMFD is distributed mainly under the articular surface, seen throughout the stages of AS, indicating that BMFD is an important pathological change of the bone marrow in AS to potentially allow early diagnosis of AS.

Objective:To analyze the clinicopathological features and prognostic factors of alpha‐fetoprotein‐producing gastric carcinoma (AFPGC).Methods:A retrospective analysis was made on 2 671 GC patients admitted from Jan 1998 to Dec 2018 , AFPGC patients and matching AFP negative GC cases were enrolled and their clinicopathological features and prognostic factors were analyzed. The survival curve was drawn by Kaplan-Meier method. Log-rank test was used to test the significance, Univariate analysis was performed by using COX proportional hazard model.Results:There were 98 AFPGC in this study accounting for 4.5% of all GC of the corresponding time period. The proportion of male to female was 2.16∶1, the average age was (65±12) years. The serum AFP levels significantly decreased after operation in most patients (median: 52 ng/ml vs. 5 ng/ml, Ｚ=-2.736, P=0.001). Serum AFP and CEA levels in patients with AFPGC before treatment were significantly higher than that in patients with AFP negative GC (both P<0.05) . Vascular invasion(62.71% vs. 40.68%) and liver metastasis (31.63% vs .6.12%) were more likely to occur in AFPGC groups (both P<0.05). However, there was no significant difference between the two groups in tumor size, location, differentiation and lymph node metastasis (all P>0.05). The prognosis of AFPGC was significant pooer than that in AFP negative GC ( P<0.05). Prognosis of AFPGC patients was significantly correlated with preoperative serum AFP level, TNM stage, lymph node metastasis, simultaneous liver metastasis and vascular invasion (all P<0.05) . COX multivariate survival analysis found that preoperative serum AFP level was independent risk factors of patients with AFPGC ( P<0.05). Conclusion:AFPGC is a special GC charactering poor prognosis .
