Objective To investigate the impact of intraoperative intra-abdominal pressure increasing on digestive system.Methods A retrospective analysis of clinical data of 132 cases of colorectal cancer patients from January 2013 to June 2016 was made. Patients were divided into groups A, B and C according to the intra-abdominal pressure, 46 cases in each group. Group A: 46 patients, 10 mmHg (1 mmHg = 0.133 kPa), group B: 45 patients, 12 mmHg, group C: 41 patients, 15mmHg. Comparison of postoperative recovery time, complications, serum cytokine levels was made among the three groups.ResultsThe number of postoperative 6h nasogastric tube pulled out, bowel recovery time, ifrst lfatus or a bowel movement, tolerance semi-liquid diet, postoperative duration of diarrhea, postoperative hospitalization time among the three groups show no statistically difference (P > 0.05). The difference of acute gastric injury (AGI), chyle leakage, anastomotic fistula, surgical bleeding, intestinal paralysis, vomiting incidence of postoperative among the three groups has no statistically differences (P > 0.05). While postoperative IL-6 level and MAP were signiifcantly increased compare with preoperative level, the difference was statistically signiifcant (P < 0.05). Postoperative TNF-α show no statistical differences compare with preoperative (P > 0.05). Postoperative serum IL-6 levels in 25 patients with intestinal paralysis was (10.71 ± 4.37) ng/L, 107 cases had high serum IL-6 levels in patients did not occur intestinal paralysis was (10.66 ± 4.13) ng/L, the difference was not statistically significance (P > 0.05).Conclusion Intra-abdominal pressure increasing during minimally invasive surgical procedure has no signiifcant effect on the digestive system in colorectal cancer patients.

Objective To assess the prevalence of the metabolic syndrome (MS) in Shanghai adults according to the criteria of the US National Cholesterol Education Programme Adult Treatment PanelⅢ ( NCEP ATP Ⅲ) definition. Methods Randomly selected adults were studied by means of stratified sampling. A cross-sectional study was conducted in Shanghai with a representative sample of 7 414 Chinese adults aged 35-74 years.Results Defined by the ATPⅢ criterion, the preliminary prevalence of MS was 19.81%. The prevalence of MS was 16.21% (95%CI 15.37%-17.05% ) after age was adjusted. The prevalence of MS was higher in female than in male (22.59% vs 16.64% ,P<0.01 ), and higher in urban than rural residents( 17.43% vs 17.16% ,P<0.01 ). The prevalence of MS increased with age in both male and female, especially in females aged above 55 years. There were 19.81% subjects with over 3 risk factors. The most common combination of four components in MS were central obesity, high triglyceridemia, low high-density lipoprotein-cholesterol and hypertension. Conclusions There is a high prevalence of MS in Shanghai adults. MS is increasingly becoming a noteworthy health problem. Early-diagnosis and integrated-methods of prevention and treatment of MS are mandatory.

Objective To evaluate contrast-enhanced ultrasound (CEUS) for the diagnosis and follow-up of hepatocellular carcinoma ( HCC) patients after percutaneous radiofrequence ablation ( RFA). Methods The data of 46 HCC cases were reviewed in our study. Results of contrast enhanced computed tomography (CT) , ultrasound contrast agent sonography and grey ultrasound were compared with each other pre- and after percutaneous radiofrequence ablation. Results Contrast agent ultrasound imaging had the same value with CT in preoperative diagnosis of HCC, with postive likelihood ratio of 1.26 and 1.31, respectively,sensitivity of 97% and 91% and specificity of 23% and 31% respectively. For grey ultrasound the positive likelihood ratio was 0.99, sensitivity and specificity was 76% and 23% respectively. The sensitivity and specificity of contrast-enhanced ultrasound after percutaneous radiofrequence ablation was 60% and 90% respectively, and the postive likelihood ratio and negative likelihood ratio was 6. 18 and 0. 44 respectively. The difference was significant while compared with CT (P = 0. 012). All cases were followed-up from 1 to 9 months, and all were alive with recurrence found by contrast-enhanced ultrasound in 3 cases. Conclusions Contrast agent ultrasound imaging is sensitive and effective in the diagnosis of HCC and follow-up after percutaneous radiofrequence ablation.

Objective To examine the expressions of AQP1 and VEGF in human hepatitis B associated hepatocellular c arcinoma and to investigate its relationship with the occurrence and development of hepatocellularcarcinoma. Methods AQP1 and VEGF expressionsin the cancer tissues and AQP1 and VEGF levels in the serum were detected in 62 cases of hepatocellula carcinomaby immunohistochemistry and ELISA , respectively. Results The expressions of AQP1 and VEGF in the liver cancers were significantly higher than in the normal tissues (P<0.01). The higher expression was related to pathologic type,degrees of differentiation and lymph node metastasis, but not related to sex, age and TNM stages. In the serum of liver cancer, the concentrations of AQP1 and VEGF were significantly higher than those in the control group. Conclusion High expressions of AQP1 and VEGF in the patients with liver cancer may be correlated to the occurrence and development of liver cancer. Plasma levels ofAQP1 and VEGF may be more meaningful for the evaluation of clinical prognosis.

Objective To investigate whether correlation exists between quantitative perfusion parameters obtained from dynamic contrast?enhanced magnetic resonance imaging (DCE?MRI) and different prognostic factors or immunohistochemical subtypes of breast cancers. Methods A retrospective analysis of DCE?MRI was performed in 87 breast cancer patients with 91 pathology confirmed breast lesions. All the patients underwent the immunohistochemistry after the operation, 80 breast cancer patients with 84 breast lesions were divided into different subtypes based on the immunohistochemical profiles. All the patients underwent plain MRI and DCE?MRI. The volume transfer constant (Ktrans), rate constant (kep) and volume of EES per unit volume of tissue (Ve) value were calculated. Results of the immunohistochemistry and observation results of the the expression of estrogen receptor (ER), progesterone receptor (PR) and human epidermal growth factor receptor?2 (HER?2) were recorded. Subtypes were also categorized. The degree of the expression of Ki?67 was observed simultaneously. Among the 87 breast cancer patients (with 91 breast lesions), 68 were ER?positive,18 were ER?negative, 60 were PR?positive, 26 were PR?negative;30 were HER?2 positive and 58 were HER?2 negative. Eighty breast cancer patients (with 84 breast lesions) were divided into different subtypes:19 were Luminal A, 49 were Luminal B, 7 were HER?2 positive subtype and 9 were triple negative breast cancer (TNBC). The quantitative perfusion parameters with diffierent expression of the receptors were analyzed through Mann?Whitney U test, the correlation between the degree of the expression of Ki?67 and quantitative perfusion parameters was obtained with Spearman test. Furthermore, the distributions of the perfusion parameters between groups according to immunohistochemical subtype were compared using the Kruskal?Wallis test. Results Ktrans and kep value were higher in tumors with ER?negative and PR?negative than with ER?positive and PR?positive and difference was statistically different ( P<0.05). There was no statistically significance in the quantitative perfusion parameters between HER?2 positive and HER?2 negative (P>0.05). The degree of the expression of Ki?67 was 5%to 90%the mean value was 33%, the median and interquartile range of Ktrans, kep and Ve value was 1.33/min (0.88/min), 2.63/min (2.34/min) and 0.51 (0.22) respectively. There was no significant correlations between the degree of the expression of Ki?67 and Ktrans and kep value (r value was 0.24 and 0.22 respectively, P value was 0.03 and 0.04 respectively), and the degree of the expression of Ki?67 was not associated with Ve (r=0.00, P=0.97). Ktrans value was lower in Luminal A and Luminal B than that in HER?2 positive subtype and TNBC, kep value was lower in Luminal A and Luminal B than that in TNBC, and Ve value in Luminal A, Luminal B and HER?2 positive subtype were higher than that in TNBC, kep value was lower in Luminal B than that in HER?2 positive subtype, statistically significance was seen among them (P<0.05).Triple?negative breast cancer showed the highest kep value (3.99/min) and the lowest Ve value (0.41) than the other subtypes. Conclusion The different subtypes of breast cancer may be predicted to some extent with quantitative perfusion parameters, and there is no correlation between quantitative perfusion parameters and the prognostic factors.
