Gastric cancer is the leading cause of death of patients with malignancy and the most common malignancy in China.Stomach is also a secretory organ,thus the carcinogenesis of human stomach always accompanied neuroendocrine differentiation.There is not a explicit definition of neuroendocrine differentiation so far,and the influence of which in gastric patients prognosis is in dispute.With the deep intensive research of gastric adenocarcinoma,diagnosis and treatment in gastric adenocarcinoma with neuroendocrine differentiation becomes increasingly concerned.

[Objective]To observe the relationship between blood uric acid(UA)level and carotid atherosclerosis(CAS)in perimenopausal women.[Methods] Two hundred and thirty-three perimenopausal women were selected.Intima media thickness(IMT)of bilateral carotid arteries were measured by colour Doppler ultrasound.They were divided into normal group(162 cases)and CAS group(71 cases)according to the results of colour Doppler ultrasound.The level of blood UA between two groups was compared and the influence factors of CAS we re analyzed.[Results] The level of blood UA in CAS group was significantly higher than that in normal group[(341 ± 86)μ mol/L vs.(293±78)μ mol/L](P ＜ 0.05).The detection rate of hyperuricemia in normal group was 10.49％(17/162),while the detection rate in CAS group was 40.85％(29/71),which had statistical significance between two groupe(P＜0.01).Pearson correlation analysis showed that CAS had positive correlation with age(r=0.233,P=0.028),body mass index(BMI)(r=0.215,P=0.044),bloodUA(r=0.249,P=0.019)and fasting plasma ghcose(r=0.214,P=0.046).AndCASwas negatively correlated with high density lipoprotein cholesterol(r=-0.224,P=0.036).Logistic regression analysis showed that after the factors of age and BMI were corrected,CAS still had significantly positive correlation with the level of blood UA(OR＝4.805,95％ CI 1.700-11.673,P ＜ 0.05).[Conclusion]Hyperuricemia is a related risk factor of the incidence of carotid atherosclerosis in perimenopausal women.

0.05). The observation about reliability markers indicated:there were no toxic and side effects.

During the reliability observation, Kechuanling Effervescent Troche indicated good clinical reliability.

Aim To investigate the anticoagulant efficacy and mechanism of a semi-synthesized sodiumβ-1,4-glucan sulfate (Na-MCS). Methods Anticoagulant activity was evaluated by means of coagulation assays in comparison with heparin. The anticoagulant mechanism of Na-MCS was disclosed by inhibitory analysis of the activities of coagulation factors using chromogenic substrates. Results 0. 6concentration. The dosage of Na-MCS required to double APTT of normal human plasma was 0.7represented a potent anticoagulation activity in vitro, which matched the efficacy of heparin in a certain range of concentrations. Na-MCS exhibited anticoagulant activity due to inhibition of the coagulation factors Ⅱa and Xa by the mediation of anti-thrombin AT-Ⅲ.

Objective To evaluate the diagnostic value of 64-row VCT coronary angiography(CTA) in diagnosing coronary artery disease.Methods 64-row VCT coronary angiography(CTA) and cathter coronary angiography(CAG) were performed in 173 patients with suspected coronary artery disease.All images were analysed at GE AW4.3 workstation,the constructed images included maximum intensity projection(MIP),mlti-planar reconstruction(MPR) and volume rendering(VR).The results were compared with that of CAG.Results 746 segments of coronary artery with diameter ＞1.5 mm were showed by CTA in 173 patients.The sensitivity,specificity,positive predictive value and negative predictive value of the CTA in detecting coronary arterial stenosis were 94.15%(193/203),95.90% and 89.77% and 97.90% respectively.Statistical analysis using a 2-related χ~2 test showed that there were no obvious differences in diagnosing coronary arterial stenosis between CTA and CAG(χ~2=1.58,P＞0.05) and in evaluating the stenosis degree of coronary artery(Kappa=0.890,P＜0.001).Conclusion 64-row VCT has important clinical value in screening coronary arterial disease and in following-up post operational effectiveness of coronary stent implantation and vascular bypass.

Ojective To investigate the clinical application value of low dose contrast agent in computerized tomography pulmonary angiography (CTPA) with spectral CT imaging.Methods Totally 52 patients suspected with pulmonary embolism underwent multi-slice spiral CT pulmonary angiography,and were randomly divided into a control group (n =27) and a research group (n=25).The research group used spectral CT with 35 ml of contrast medium and the control group used 64-slice CT with conventional 80 to 90 ml of contrast medium.The CT values of the pulmonary trunk,left pulmonary artery (LPA),right pulmonary artery (RPA),pulmonary vein and ascending aorta were measured.The contrast to noise ratio (CNR) of the pulmonary artery was also calculated.In addition,the image quality of CTPA was evaluated independently by two experienced radiologists.Results The CT values (HU) of the pulmonary trunk,left pulmonary artery(LPA),right pulmonary artery (RPA) in the research group were (432.2±63.4),(373.5±48.8),(381.4±53.6) and (62.5-±6.4),respectively,and significantly higher than those in the control group,showing statistical differences (P＜0.05).The evaluation results of the CTPA images by two radiologists showed that the image quality in the research group was better than that in the control group (P＜0.05).Conclusion The image quality of pulmonary angiography with spectral CT using low contrast medium dose can be improved compared with the conventional spiral CT.

Objective To study the expressions of osteopontin (OPN),caspase-3 and mt-P53 proteins, and their relationship in gliomas. Methods Seventy gliomas specimens of patients (glioma group) were selected, and 10 samples of non-glioma brain tissue were used as control group. The SP method was used to detect the positive rates of protein expressions of OPN, caspase-3 and mt-P53 between two groups. The relationship between protein expressions of OPN, caspase-3 and mt-P53 in gliomas and grade of gliomas were detected by Western blot assay. Spearman rank correlation was compared between the positive expression of OPN, caspase-3 and rate mt-P53. Results The positive expression rates of OPN and mt-P53 were significantly higher in glioma group (64.29%and 60%) than those of control group (no positive expression), but the positive expression rate of caspase-3 was significantly lower than that of control group (47.14%vs. 90%, P<0.05). There were no significant differences in OPN, caspase-3 and mt-P53 expressions between different gender, age, tumor size and tumor position (P>0.05). The higher the WHO classification, the higher the positive expression rates of OPN and mt-P53 (P<0.001), and the lower the positive expression rate of caspase-3 (P<0.001). With the increased level of glioma grade, OPN and mt-P53 protein levels were increased, but caspase-3 protein expression level was decreased. There was a negatively correlation between OPN and the positive expression of caspase-3, but there was a positive correlation between OPN and the expression of mt-P53 (rs=-0.720 and 0.722, P<0.05). There was a negative correlation between caspase-3 and mt-P53 expressions (rs=-0.556, P<0.05). Conclusion The higher the WHO classification, the higher the positive expression rates of OPN and mt-P53, while the lower the positive expression rate of caspase-3. The study reveals that OPN, caspase-3 and mt-P53 expressions are associated with the occurrence and the progress of gliomas. The combined detection of them can contribute to the judgment of biological behavior of gliomas.

Background and purpose:The American College of Surgeons Oncology Group (ACOSOG) Z0011 trial has been described as practice-changing of sentinel lymph node (SLN) positive breast cancers. The goal of this study was to determine the exportability of the criteria deifned by Z0011 trial for selecting patients who are eligible for avoiding axillary lymph node dissection (ALND) after a positive sentinel lymph node biopsy (SLNB) result in China.Methods:We collected 194 breast cancer patients with positive SLNs and classiifed them into two groups according to Z0011 criteria. One group was consisted of patients who were eligible for omitting ALND and with SLNB only. The other one was ALND group. Then the patients of SLNB group were compared with cohort included in the Z0011 trial and the ALND group of this study separately.Results:Seventy-seven patients were potentially eligible for omitting ALND and 117 patients were still needed to have ALND. Compared with Z0011 cohort, the SLNB group in this research had signiifcantly more T1 stage and ER positive tumors (P<0.05). More patients in SLNB group had positive LNs with the number less than 3 and negative NSLNs (P<0.05). The ALND group had more T2 and T3 stage tumors than the SLNB group but the difference was not signiifcantly. The number of positive LNs in ALND group was higher than the SLNB group signiifcantly (P<0.05). More patients in the ALND group had positive non-sentinel lymph node (NSLN) than the SLNB group and the difference was also signiifcantly (P<0.05).Conclusion:Applied to the SLN positive patients in this study, Z0011 criteria could make patients with better prognosis and lower risk than Z0011 cohort be selected and let these patients avoiding ALND more safely.

Background: Although there are some Chinese herbal medicines in treatment of constipation, but no multi-center randomized controlled trials have been carried out to prove their effectiveness. Objective: To evaluate the safety and efficacy of Yunchang Capsule in treatment of functional constipation with deficiency of both qi and yin and internal accumulation of poisonous pathogenic factors syndrome, and to explore the clinical dosage. Design, setting, participants and interventions: A randomized, double-blinded controlled, multicenter trial was conducted. A total of 240 patients with functional constipation from West China Hospital of Sichuan University, Affiliated Hospital of Chengdu University of Traditional Chinese Medicine, Affiliated Hospital of Jiangxi University of Traditional Chinese Medicine, the First Affiliated Hospital of Tianjing University of Traditional Chinese Medicine and Fujian Academy of Traditional Chinese Medicine were randomly divided into three groups: low dose group (80 cases), high dose group (80 cases) and control group (80 cases). Patients in the low dose group were treated with two pills (0.35 g/pill) of Yunchang Capsule and one pill of Yunchang Capsule simulant for three times daily; patients in the high dose group were treated with three pills (0.35 g/pill) of Yunchang Capsule for three times daily; and patients in the control group were treated with three pills (0.35 g/pill) of Biantong Capsule for three times daily. The therapeutic course was 14 days. Main outcome measures: Clinical symptoms, syndromes, and adverse effects were observed before and after the treatment, and blood, urine and stool tests, hepatorenal function and electrocardiogram were also examined. Results: Two cases were excluded, eleven cases were lost to follow-up, and there were 234 patients entered to intention-to-treat (ITT) analysis. After the treatment, the therapeutic effects were calculated by full analysis set (FAS) and per-protocol population set (PPS) analysis respectively. The effects on functional constipation in FAS showed the response rates in the low dose, high dose and control groups were 86.25% (69/80), 82.90% (63/76), and 70.52% (55/78) respectively, and PPS analysis showed the response rates were 85.71% (66/77), 83.56% (61/73), and 70.13% (54/77) respectively. There were no significant differences among the three groups (P>0.05). The effects on traditional Chinese medicine syndrome in FAS showed the response rates in the low dose, high dose and control groups were 78.75% (63/80), 69.74% (53/76), and 67.95% (53/78) respectively, and PPS analysis showed the response rates were 77.92% (60/77), 69.87%(51/73), and 67.53% (52/77) respectively. There were also no significant differences among the three groups (P>0.05). No severe adverse events were observed. Conclusion: Both low dose and high dose of Yunchang Capsule are effective and safe in treatment of functional constipation with deficiency of both qi and yin and internal accumulation of poisonous pathogenic factors syndrome.
