Objective To investigate the influence and clinical significance of single and dual-chamber pacing on central aortic pressure (CAP) and augmentation index (AI) in non-smoking individuals. Methods Totally, 83 non-smokers with pacemaker-implanted were consecutively enrolled in this study, and they were divided into three groups:dual-chamber pacemaker group (DDD, n=35), single-chamber pacemaker group (VVI, n=33) and control group (n=15). Heart rate (HR), CAP, AI, systolic blood pressure (SBP) and diastolic blood pressure (DBP) were measured in three groups of patients. Finally, DDD pacing mode was turned into VVI pacing mode in patients of DDD group and the indexes were measured again. All of the indexes were recorded and analyzed. Results There were no significant changes in baseline characteristics and laboratory data between three groups (P>0.05). Left atrial diameters were significantly higher in VVI group than those of control group (P<0.05). Values of CAP were significantly higher in DDD group than those of control group and VVI group (P<0.05). Values of AI, corrected AI (AIc) and brachial BP were significantly higher in DDD group than those of VVI group (P<0.05). Values of CAP and brachial BP were significantly lower in VVI group than those of control group (P<0.05), while no significant changes were found in AI and AIC between VVI group and control group (P>0.05). All of these indexes (CAP, AI and brachial BP) were significantly reduced after the pacing mode was changed (P<0.05). Conclusion In non-smokers, dual-chamber pacing mode can increase CAP and AI.

Objective To evaluate the effect of neoadjuvant chemotherapy on lymph node micrometastasis and DC cell number in stage Ⅲ gastric cancer patients.Methods Lymph node micrometastases in pathologically negative lymph nodes from 76 stage Ⅲ gastric cancer patients [56 cases with neoadjavant chemotherapy (NCT) and 20 cases without],were assessed by cytokeratin-20 antibody.Dendritic cells (DC) in HE positive lymph nodes,HE negatives near tumor foci and HE negatives far foci were assessed by CD83 antibody respectively.Patients were divided into four groups:group 0 (20 cases without NCT),group 2 (two courses of NCT in 29 patients),group 3 (three courses of NCT in 16 patients),group 4 (four courses of NCT in 11 patients).Results In NCT group there were two patients with micrometastases (2/56).All the patients were with micrometastases in control group (20/20).Difference was statistically significant (P =0.000).In HE-positive lymph node group:the number of CD83-positive DC in 2 times group,3 times group,and 4 times group when compared with no chemotherapy group were statistically significant (P20 =0.001,P30 =0.000,P40 =0.000).In HE-negative lymph node near foci group:the number of CD83-positive DC in 3 times group,and 4 times group compared with 0 group were statistically significant increased (P30 =0.001,P40 =0.001).In HE-negative lymph node far foci group:the number of 4 times group was significantly higher than 0,2 and 3 group (P40 =0.000,P42 =0.000,P43 =0.001).Conclusions Neoadjuvant chemotherapy is effective in the prevention of lymph node micrometastases in stage Ⅲ gastric carcinoma and it increases the number of mature dendritic cells in lymph nodes.

It's difficult to diagnose precancerous lesion and early cancer for a long time, because both of them haven't typical morphological characteristics. As a novel diagnostic modality, fluorescence endoscopy can accurately reflect minimal changes in human's tissue, thus making a meaningful progress for cancer diagnosing. 200 patients were examined by fluorescence endoscopy to evaluate the diagnostic value. The overall accuracy, sensitivity and specificity for detecting malignant gastrointestinal tumor was 94.0%, 94.6% and 93.5%, respectively. Thus, fluorescence endoscopy can be used to diagnose malignant gastrointestinal tumors with high validity and reliability, and is advantageous over conventional white light endoscopy especially in detecting the atypical and suspicious lesions. Furthermore, fluorescence endoscopy can also guide target biopsy, is significant to improve the early cancer detection rate, has a broad development prospect.

Objective To evaluate the histological response and the clinical value in laparescopic colorectal surgery combined with preoperative regional intra-arterial chemotherapy(PRAC). Methods In cases of rectal cancer and fiver metastases selective regional intra-arterial chemotherapy and iodinated oil embolism was carried out in 23 cases of colorectal carcinoma. After 1 to 11 days laparoseopic radical resection was done, specimens were sent for histopathological examination. We analyzed the correlation between tumor differentiation and TNM stage, compared the effect of PRAC with PRAC + embolism by the criteria of histological response of chemotherapy. χ2-test was used to compare interclass correlation.Results The histological effect in the 23 cases of PRAC level 0 was in 2 cases, level Ⅰ in 7 cases, level Ⅱ in 10 cases, and level Ⅲ in 2 cases. The overall effective rate was 91% (21/23). In the 15 cases with lymph node metastases, the effective rate was 87% (13/15). There was no significant statistic correlation between tumor differentiation or TNM stage and histological response. PRAC associated embolism had a better histological response compared to PRAC alone. Conclusions Preoperative regional intra-arterial chemotherapy had marked therapeutic effect on histological response to the colorectal carcinoma patients of various tumor differentiations and TNM stage, especially combining with the embolism to rectal cancer could improve the efficacy.
