Objective To investigate the effect of standardization regional lymphadenectomy in radical resection of ductal adenocareinoma in the pancreatic head.Methods On the basis of routine panereaticoduodenectomy(whipple proceduce),we performed the standardization regional lymphadenectomy,the emphasis of the procedure was the resection of wide nodes,particularly the mesenteric root lymph nodes(14abcd),the paraaortic lymph nodes(16a2b1),the hepatoduodenal ligament lymph nodes(12abpeh),hepatic artery(Group 8)and coeliacus lymph nodes(Group 9). Results Eleven patients underwent this procedure,there was no operative mortality,1 case occurred pancreatic fistula,the lymph nodes metastasis occurred in 7(63.6%)patients,the posterior pancreaticoduodenal lymph nodes(Groupl3)and superior mensenteric artery(Groupl4)was the predominant metastatic site of the tumor,the rate of the second site metastasis to lymph nodes was 57.1%.of the 11 cases follow-up 1 died. Conclusion The radical pancreaticoduodenectomy combined with wide resection of standardization regional lymph nodes is a safe and effective procedure of the treatment of adenocarcinoma of the head of the pancreas.but the long-term survivalrate must be valued objectively with many cases.

In order to investigate the interactions between first- and second-order motion perception systems, 14 adult subjects with normal or correct to normal visual acuity were recruited and divided into two groups. Then these two groups were trained, in their parafovea, to discriminate the direction of first- and second-order motion gratings respectively. The spatial frequency of the gratings used in study was fixed at 2 cycles/degree and the temporal frequency was fixed at 8 Hz during training. Contrast sensitivity of subjects in these two training groups for first- and second- order motion was measured before and after 7 days' training to estimate the effects of training. In addition, the differences between the two training groups(14 subjects) and another control group (11 subjects) were studied. The results showed that: 1) the training with first-order motion gratings can improve subjects' performance in first-order motion direction discrimination but the improvement can't be transferred to the performance in second-order motion task; 2) the training with second-order motion gratings can improve subjects' performance in both first- and second-order motion direction discrimination tasks. In conclusion, an " asymmetric transfer" occurred between the training effect of first- and second-order motion gratings. These results indicate that there are two mechanisms for perceiving first- and second-order motion respectively. However, they are not completely different from each other but only partly separated.

Objective In order to understand whether recombinant human growth hormone(r-hGH) can improve the idiopathic short stature(ISS) boys' final adult height(FAH).Methods We measured 16 cases diagnosed as ISS boys FAH, divided into 2 groups, of which 9 cases were not given r-hGH treatment, treatment group ,7 patients received r-hGH treatment, a dose of 0.1 ～ 0.13 U· kg-1·d-1, before going to sleep subcutaneous injection, duration of treatment was 6 ～ 20 months ( 11.9 ± 5.2 months).Results The treatment group compared with the average FAH FAH observation group had significantly improved the average(t =2.219,P<0.05).Conclusion r-hGH can improve the ISS boys FAH, but early treatment, the longer the course the more obvious effects.

Objective To investigate the mechanism of ventricular dilation-induced arrhythmias by dilating isolated rat hearts. Methods Isolated rat hearts were perfused by Langerdorff method. After equilibration, 80 hearts were randomly divided into four groups as follows: (1) control group (n=20), (2) Ca2+ preconditioning (CPC) group (n=20), (3) streptomycin group (n=20), and (4) CPC + streptomycin group (n=20). A latex balloon which can be filled with fluid was anchored in the left ventricle through the left atrium and mitral valve. Epicardial ECG of the left ventricle, left ventricular pressure, coronary flow and heart rate were recorded before and during ventricular dilation by injecting fluid into the latex balloon. The rate and duration of ventricular dilation-induced arrhythmias were recorded. Results Under the same increase in ventricular end-diastolic pressure made by inflation of the balloon, the rate of arrhythmias was 100% and duration of arrhythmias was 2.56±0.46 s in the control group. Both the rates of premature ventricular beat (90 %) and ventricular tachycardia 70 % ) were high. Compared with the control group, the total rate (60 % ) of arrhythmias was lower, and duration (1.67±0.61 s ) of arrhythmias was shorter in the CPC group. Both the rates of premature ventricular beat (60%) and ventricular tachycardia (40%) were low comparatively. The rate of arrhythmias (45 %) was lower and duration ( 1.64±0.42 s)of arrhythmias was shorter, and the rates of premature ventricular beat (30 % ) or ventricular tachycardia (35 %) were lower in the streptomycin group than in the control one. The least ventricular dilation-induced arrhythmias occurred in the CPC + streptomycin group. The rate of arrhythmias (10%) was the lowest and duration (1.01±0.37s) of arrhythmias was the shortest; both the rates of premature ventricular beat (5%) and ventricular tachycardia (10%) were the lowest. Conclusions Ventricular dilation may induce arrhythmias in isolated rat hearts. Stretch-activated ion channel and the increase in [Ca2+]I are supposed to play important roles in the pathological mechanism.
