The fiber length has only little influence on the basic density within the growth rings, and significant correlation at 0.01 levels was found between the basic density and the fiber length among the different rings. Only slight negative correlation was found between the basic density and the fiber width within the growth rings, but significant positive correlation at 0.01 levels was indicated between the basic density and the fiber width among the growth rings, contrary to that of fiber length. It was demonstrated that significant positive correlations at 0.01 levels between the basic density and fiber double wall thickness, fiber length to width ratio and double wall thickness to diameter ratio, significant negative correlations at 0.01 levels between the basic density and fiber diameter and diameter to width ratio, only slight negative correlation between the basic density and fiber width both in the same growth rings and among the different growth rings. No significant correlation was found between the basic density and the vessel morphological features, nor was the tissue proportion in the same growth rings. But among the different rings, it was found there was significant positive correlation at 0.01 levels between the basic density and the fiber proportion among the different rings, and significant negative correlation at 0.01 levels between the basic density and vessel-elements proportion and ray proportion, only slight negative correlation between the basic density and the parenchym proportion. Significant or no significant negative correlation was found between the basic density and the microfibril angle in the same growth rings, but significant negative correlation was found between the basic density and the microfibril angle among the different growth rings.

生长轮内纤维长度对基本密度的影响不大，而在不同生长轮间纤维长度与基本密度达极显著正相关，纤维宽度与此相反，同一生长轮内纤维宽度与基本密度极显著负相关，不同生长轮间只有微弱负相关；基本密度与纤维双壁厚、长宽比、壁腔比在生长轮内和生长轮间均呈极显著正相关，而与胞腔直径、腔径比均呈极显著负相关，仅与纤维宽度呈微弱的负相关；导管形态对基本密度的影响不显著；同一生长轮内组织比量对基本密度的影响也不显著，但不同生长轮间基本密度与纤维比量呈极显著正相关，与导管比量和木射线比量呈极显著负相关，与轴向薄壁细胞比量仅呈不显著负相关；生长轮内基本密度与微纤丝角呈显著或不显著负相关，但在生长轮间这种负相关达到极显著水平。

Results: six patients with vagal reflection were cured by intravenous atropine, 2 with pericardial hemorrhage were treated by pericardiocentesis, 1 patient developed hypotension due to occlusion of the mitral valve orifice by the catheter was corrected by shortening the duration of the catheter in left ventricle, the blood pressure of 1 patient with rapid atrial flutter was elevated by intravenous cedilanid, the blood pressure of 1 patient with hypotension of unknown origin was elevated by vasopressor and atropine.

结果：其中迷走神经反射6例，经静脉注射阿托品纠正；心包出血2例，心包穿刺抽液血压至正常；球囊导管阻塞二尖瓣口1例，缩短导管停留在左心室时间，可以避免低血压反应；快速心房颤动1例，使用西地兰减慢心室率，血压回升；原因不明1例，经使用升压药及阿托品后血压改善。

A central venous catheter was inserted for hemodynamic monitoring and blood transfusion. Cardiac tamponade occurred secondary to perforation of the superior vena cava by the central venous catheter. The patient's hemodynamic status became stable after pericardiocentesis. One week later she was discharged with no sequelae during the three month follow-up.

患者术后装置中央静脉导管以利於血行动力的评估及输血，病患进行中央静脉导管术时因上腔静脉穿刺破裂导致心包膜填塞及休克，经紧急照会心脏科医师后立即给予心包膜穿刺术，术后患者血压渐趋稳定情况好转於一星期后出院，经过三个月的追踪亦无后遗症。

Once correctly recognized, pericardiocentesis started via subxyphid routine under flouscopy, including insertion of 145 cm guide wire, sheath and pigtail catheter.

处理方法：患者取平卧位，用18号静脉穿刺针带注射器及造影剂，在X线透视下于剑突下进行心包穿刺。穿刺针进入心包后立即注射5 ml造影剂，若造影剂沿心包分布则肯定穿刺针入心包。然后送入145 cm导引钢丝，并经钢丝送入鞘管及猪尾导管。引流完毕后留置猪尾导管24小时。

In conclusion, ISD lying in adipose tissue unaccompanied by other elements, present in 47.6% of pancreatic resections when peripancreatic soft tissues away from the tumor are sampled, is a very specific finding for carcinoma that may be instrumental in the diagnosis and staging of carcinoma as well as margin evaluation.

总结：ISD单独出现于脂肪组织，即出现于47.6%的导管腺癌切除标本的周围软组织中，而这些软组织都远离癌肿，这对于胰腺导管腺癌来说是个非常特别的发现，这或许对肿瘤的诊断、分期和生长潜能评估都有所帮助。

The antiquity of Schisandraceae is supported by the presence of single vessel, scalariform perforation plates with many bars, scalariform vessel pitting and heterogeneous rays.

在五味子科中发现木材导管单生、具梯状穿孔板、导管壁具梯形排列的纹孔以及木射线异型等原始性状，支持五味子科在被子植物中的原始地位。

The wood anatomy of 21 collections of 7 species within Kadsura Kaempf. ex Juss. and 14 collections of 8 species of Schisandra Michx., representing a large proportion of two genera in Schisandraceae, was investigated using light microscopy and scanning electron microscopy. Several features in the secondary xylem, such as types of vessel elements, arrangement of vessel-ray pitting, types of ray and shape of the body ray cells, show consistent characteristics at the family level, which support the view that Schisandraceae represents a monophyletic group.

在光学显微镜和扫描电镜下观察了南五味子属Kadsura 7种21个样品和五味子属Schisandra 8种14个样品的木材解剖特征，结果表明次生木质部的导管分子类型、导管－射线间纹孔的排列方式、射线类型、射线细胞形状等性状在科的水平上很稳定，这些共同特征都支持五味子科Schisandraceae是比较自然的类群。
