Objective To investigate the possible role of X-box binding protein (XBP1) expression at mRNA level in the hepatocarcinogenesis. Methods The expression of XBP1 at mRNA level was determined with RT-PCR method in liver carcinoma (42 cases), liver tissue adjacent to carcinoma (15 cases) and normal liver tissue (15 cases). XBP1 mRNA relative expression level was obtained by comparing with GAPDH mRNA level. The correlation between XBP1 expression and clinicopathological features of liver carcinoma were respectively analyzed. Results RT-PCR results showed that the expression of XBP1 mRNA in liver carcinoma cases (0.4396 ±0.0241) was significantly higher that that of liver tissues adjacent to carcinoma (0.4152±0.0252) and normal liver tissue (0.4095 ±0.0149), (F =12.79,P =0.001). No significant differences in the expression of XBP1 were found among different age and sex of the patients, different location, histological types, grade and metastatic status in liver carcinoma (P >0.05). Conclusion Increased expression of XBP1 mRNA is found in liver carcinoma but no correlation could be seen between XBP1 expression and clinicopathological features, which XBP1 is involved in the hepatocarcinogenesis.

Objective To explore the feasibility of diffusion-weighted imaging (DWI) in assessing the efficacy of chemoradiotherapy for cervical cancer.Methods Data of magnetic resonance imaging (MRI) and DWI were analyzed in 32 patients with uterine cervical cancer received conventional prior to chemoradiotherapy and after 1 and 3 months of therapy.13 cases of normal controls also had been examed by MRI and DWL DWI with b values of (0,300) s/mm2 and b values of (0,600) s/mm2 were performed in all patients.Pretreatment post-treatmentADC values were compared between the health group and patients group.Results When the b =300 s/mm2,normal cervical average ADC value was (1.72±0.31)×10-3 mm2/s,cervical cancer was (1.10±0.24)×10-3 mm2/s before treatment and was (1.61±0.23)×10-3 mm2/s after treatment.When the b =600 s/mm2,normal cervical average ADC value was (1.46±0.25)×10-3 mm2/s cervical cancer was (0.89±0.21)×10-3 mm2/s before treatment and was (1.54±0.18)×10-3 mm2/s after treatment.When b =300 s/mm2,ADC value was higher than when b =600 s/mm2.ADC values of cervical cancer was significantly lower than that of the normal cervix group,ADC values of cervical lesions after chemoradiotherapy was significantly higher than that before chemoradiotherapy (P ＜ 0.05).In the same group with different b values,ADC value was not significant (P ＞ 0.05).Conclusion Joint observation of DWI and ADC values could be more objective and accurate in the analysis of the disease and would help to evaluate the efficacy of chemoradiotherapy.

Objective To clarify the role of insulin resistance on spontaneous recanalization of infarct-relat-ed arteries in the early phase of acute ST-elevation myocardial infarction (STEMI) in patients with normal glucose tolerance. Methods 141 consecutive patients with normal glucose tolerance and acute STEMI were enrolled in our study. Subjects were divided into TIMI 0-1 group (n =91 ) and TIMI 2-3 group (n =50) by primary coronary angi-ngraphy (CAG). The Gemini score and 0-3-vessel disease score estimated the severity and extent of coronary artery disease (CAD). Metabolic parameters and homeostasis model assessment for insulin resistance (IRI) were deter-mined. Results Serum level of fasting insulin, IRI and Gemini score were higher in TIMI 0-1 group than in TIMI 2-3 group [ (11.52±6.22)mU/L vs (7.54±3.65)mU/l,(2.79±2.32) vs (1.73±1.26),(59.17±26.95) vs ( 38.46±22.74) ( P <0.01)]. IRI was positively associated with Gemini score (r=0.185,P <0.05 ). Multivariate Logistic regression analysis revealed that IRI was independent risk factor influencing spontaneous recanalization of in-farct-related urteries(OR=2.87,95% CI=1.09-7.57,P<0.05). Conclusion Insulin resistance is independent risk factor influencing spontaneous recanalizafion of infarct-related arteries in the early phase of acute STEMI in pa-tients with normal glucose tolerance.
