This paper describes a new method based on ICA to transmit hidden Chinese characters, where a color image is used as the host image and analyzed to get its independent components. After the Chinese characters having been coded, the code was embedded in the lower significant bits of the proper independent components. Thus an image with the Chinese characters hidden in it can be composed, and then transmitted on the Internet. By this method, the Chinese characters can be transmitted secretly.

This paper describes a new method based on ICA to transmit hidden Chinese characters, where a color image is used as the host image and analyzed to get its independent components. After the Chinese characters having been coded, the code was embedded in the lower significant bits of the proper independent components. Thus an image with the Chinese characters hidden in it can be composed, and then transmitted on the Internet. By this method, the Chinese characters can be transmitted secretly. This method has been simulated in PC. The experiments show that using this method the transmission ratio of the Chinese characters and its security can be considerably high under the condition of keeping image quality relatively high.

本文描述了一种基于独立成份分析 (ICA)的汉字信息隐密传输方法。该方法以彩色图像为寄主图像 ,对其进行ICA分解 ,求出其中的独立成分 ,再将汉字信息以编码形式 ,隐藏在对彩色图像质量影响最小的独立成分低位端 ,从而实现汉字信息的隐秘传输。该方法已经在PC机上进行了模拟 ,实验结果表明 ,该方法在保证图像质量条件下 ,有较高的嵌入率和较好的可靠性。

AIM:To compare the effects of sphincter preservation therapy and abdominoperineal excision operation and to investigate their influence on the defecation and quality of life of patients. METHODS:The operation methods for 75 patients with middle or lower rectal carcinoma and their prognosis were analyzed retrospectively from 1991 to 1998. RESULTS:Twenty eight patients were performed sphincter preservation operation by handsewn coloanal anastomosis.Twenty patients were performed sphincter preservation operation...

AIM:To compare the effects of sphincter preservation therapy and abdominoperineal excision operation and to investigate their influence on the defecation and quality of life of patients. METHODS:The operation methods for 75 patients with middle or lower rectal carcinoma and their prognosis were analyzed retrospectively from 1991 to 1998. RESULTS:Twenty eight patients were performed sphincter preservation operation by handsewn coloanal anastomosis.Twenty patients were performed sphincter preservation operation by end to end anastomosis.Two patients with villous adenoma underwent transanal resection.Two patients underwent pull through operation.All the 62 cases preserved their anuses successfully.Twenty three patients were performed Miles operation.The sphincter preservation rate was 69.33%.The local recurrence rate of the sphincter preservation group and the abdominoperineal excision group were 7.69%(4 cases,4/52) and 8.69%(2 cases,2/23)respectively,according to the follow up.The five year survival rate of the sphincter preservation group and the abdominoperineal excision group were 73.07%(38/52)and 69.56%(16/23) respectively. CONCLUSION:There was no significant difference between the sphincter preservation group and the abdominoperineal excision group in the five year survival rate and the local recurrence rate.The sphincter preservation operations may be an excellent option in the treatment of lower rectal carcinoma for the selected patients.

目的:比较保肛手术与Miles手术疗效,探讨其对患者排便功能和生活质量的影响。方法:回顾性分析1991/1998收治的75例中、低位直肠癌病例,手术治疗的方法以及预后。结果:28例行前切除根治术超低位吻合。20例以吻合器行低位端端吻合,绒毛状腺瘤恶变2例行局部切除术,2例行结肠拉出术,均成功保留了肛门。23例患者行Miles手术。保肛率69.33%。经随访,保肛组局部复发4例(4/52),占7.69%,5年生存率为73.07%(38/52),Miles手术组局部复发率为2例(2/23),占8.69%,5年生存率为69.56%(16/23)。结论:低位直肠癌中选择部分病例实施保肛手术是可行的,5年生存率和局部复发率与Miles手术无差异。

Objective To study the possibility of repair of the ulnar nerve injuried in arm by end-to-side neurorrhaphy. Methods Eighteen rabbits were studied.On the left side the ulnar nerve was repaired in an end-to-end fashion in arm.At the same time the ulnar nerve was transected in forearm,and the distal end of the nerve was sutured to the windowed median nerve by end-to-side fashion.On the right side the ulnar nerve was repaired in an end-to-end fashion just in arm as control.Regeneration was tested via electromyographic...

Objective To study the possibility of repair of the ulnar nerve injuried in arm by end-to-side neurorrhaphy. Methods Eighteen rabbits were studied.On the left side the ulnar nerve was repaired in an end-to-end fashion in arm.At the same time the ulnar nerve was transected in forearm,and the distal end of the nerve was sutured to the windowed median nerve by end-to-side fashion.On the right side the ulnar nerve was repaired in an end-to-end fashion just in arm as control.Regeneration was tested via electromyographic examination and histological examination at postoperative 4 weeks in group A,postoperative 8 weeks in group B and postoperative 12 weeks in group C,with 6 rabbits each. Results Just on the left side nerve regeneration in the hypothenar muscles inervated by the ulnar nerve could be detected at postoperative 4,8 and 12 weeks.Histological examination showed that the number and density of regenerated nerve fibers were increased at postoperative week 4,8 and 12 respectively.On the right side there was degeneration. Conclusion End-to-side neurorrhaphy is a new valuable method for repair of ulnar nerve injuried in arm.

目的探讨高位尺神经损伤后尽早恢复手内在肌功能的一种修复方法。方法纯种大耳白兔18只,采用同体自身对照方法。左侧高位尺神经切断后直接吻合,同时在低位(前肢远端)切断尺神经,将其远侧断端与正中神经外膜开窗处作端侧吻合为实验侧,右侧尺神经高位切断后直接吻合为对照侧。按手术先后分为A、B、C三个时间组,分别于术后4、8、12周时做电生理检测和组织学检查。结果A、B、C三组实验侧均测出诱发电位,而对照侧均未测出诱发电位。组织学观察结果显示术后4、8、12周时实验侧神经纤维数量、密度随时间延长而逐渐增加,而对照侧未检测到再生神经纤维。结论高位尺神经损伤后在高位端端吻合恢复手外在肌功能的同时加低位端侧吻合可作为尽早恢复手内在肌的功能的一种新方法。
