ABSTRACT
Objective To evaluate the efficacy and safety of combined use of insulated-tip knife, titanium clips and transparent caps in the resection of large pedunculated colorectal polyps. Methods Therapeutic method: with the assistance of transparent cap, 1~3 titanium clip(s) were applied to the base of the stalk to block blood supply of large polyps and then insulated-tip knife was utilized to resect polyps by cutting the stalk. Research method: retrospectively analyze the clinical data of 45 large pedunculated colorectal polyps (head ≥ 2.0 cm) which were treated by the method mentioned above from January 2014 to December 2015. Statistics of procedure time, clip numbers, complication rates were used to assess the effect of the treatment. Results 45 large polyps were successfully removed one time without any severe complications of bleeding or perforation during procedure except a very small amount of blood were oozing from the cutting edge in 3 cases. There were also no delayed complications of bleeding or perforation after procedure. The average number of titanium clip was 2.7 and the average operating time was (5.7 ± 1.2) min (range 3 ~ 12 min). Conclusion Combined application of insulated-tip knife, titanium clips and transparent cap inthe resection of large pedunculated colorectal polyps is safe, effective and convenient to conduct.

ABSTRACT
<p><b>OBJECTIVE</b>To observe the effect of Naoxintong Capsule (NC) on the vascular endothelial function and the infarct size of patients with acute myocardial infarction (AMI).</p><p><b>METHODS</b>One hundred and four patients with AMI were randomly assigned to the NC group (Group A, 36 cases), the Tongguan Capsule group (Group B, 32 cases), and the conventional Western medicine group (Group C, 36 cases). The conventional Western medicine was given to the three groups. NC was additionally given to Group A, and Tongguan Capsule was additionally given to Group B. The therapeutic course for all was 4 weeks. The plasma nitric oxide (NO), endothelin (ET), von Willebrand factor (vWF) were detected in the 3 groups before and after treatment. The inner diameter of brachial artery was examined by ultrasonograph. The flow-mediated dilation (FMD) and the nitroglycerin-mediated dilation (NMD) were calculated. The ECG QRS integral and the infarct size were assessed.</p><p><b>RESULTS</b>There was no significant difference in the vascular endothelial function, ECG QRS integral, or the infarct size among the three groups before treatment (P > 0.05). Compared with before treatment, NO and NMD obviously increased after treatment in Group A and Group B, while the vWF and the infarct size obviously decreased in Group A, all showing statistical difference (P < 0.05). Compared with those in Group C, the NO, FMD, NMD significantly increased and ET obviously decreased in Group A and B after treatment (P < 0.05). The ECG QRS integral and the infarct size also decreased, with statistically significant differences in Group A (P < 0.05). Better effects on improving NO, NMD, and vWF were obtained in Group A than in Group B (P < 0.05).</p><p><b>CONCLUSION</b>NC could reduce the infarct size of AMI patients possibly through improving the vascular endothelial function.</p>

To study the program of evaluating mothers and infants after 6 months of cord blood donation, from June 1998 to February 2004, all mothers after 6 months of cord blood donation were followed-up by phone calls or letters to report on the health condition. The results showed that when 3 195 mothers were visited by phone calls, 18 mothers declined to answer. 392 letter were send to those who could not be found by phone, 15 of whom wrote back. The average time to talk with each mother was approximately 12 minutes. Follow-up on the baby donors showed two cases with chromosome abnormality, one with hypothyroidism, one with neutropenia, one with albinism and 5 dead with unclear reasons. The cord blood components from all these abnormal donors found were discarded. In conclusion, the programs to evaluate mother and baby after 6 months of cord blood donation seems important in quality control of the components stored in cord blood bank.

<p><b>OBJECTIVE</b>To develop a rapid and reliable technique for the detection of Down's syndrome.</p><p><b>METHODS</b>The peripheral blood samples were collected from twenty-five Down's syndrome patients and fifty normal individuals. Four polymorphic loci on chromosomes 21, 1, 19 were amplified by real-time fluorescence quantitative PCR, and then four pairs of deltaCt values were analytically compared between the two groups.</p><p><b>RESULTS</b>The deltaCt values of Down's syndrome patients were significantly lower than those of normal individuals, and the reference ranges for clinical application were primarily established. The difference between the two groups was highly significant (P < 0.001), and the reference ranges between the two groups were not overlapped. Real-time quantitative PCR technique can effectively differentiates Down's syndrome samples from the normal fetuses; furthermore, the results were consistent with those of the karyotype analysis.</p><p><b>CONCLUSION</b>Real-time quantitative PCR is a fast and reliable method that may provide a new approach for rapid detection of Down's syndrome.</p>
