  feature decomposition
Early work on feature recognition focused on finding single best feature decomposition for a given part.
      
Fed from the receptive field controller, primal feature separation takes place in the feature decomposition components.
      
This heuristic reduces the complexity of the feature decomposition by eliminating unstable/ambiguous features.
      
The second choice is given by the sparse invariant feature decomposition outlined in the previous section.
      
  feature groups
The sequence is determined by analyzing the feature information such as the nested relations and the possible probe approach directions of the features, and by forming feature groups.
      
A feature may participate in only on CompFeature, but many FeatureGroup's.
      
All feature groups are therefore ordered in terms of relevance to the representative pattern.
      
By combining the feature groups it was anticipated that the overall classification performance would be improved.
      
Combining features from different feature groups yields improvements in performance over the best individual feature participating in the combination.

y using a modified polymerase chain reaction(PCR) and restriction fragment length polymorphisrn(RFLP) technique, we detected Kras codon 12 muta-tion in 102 formalin-fixed, paraffinernbedded tissuesfrom surgical samples of lung cancer patients. The X ̄2test was used to determine the statistical significance ofdifference, according to the presence or absence of mutation in codon 12 of K-ras oncogene. We found 25 cas-es (24%) positive for mutation of K-ras 12 codon. Mu-tation occured in 6 of the 40 cases (15 %)...

y using a modified polymerase chain reaction(PCR) and restriction fragment length polymorphisrn(RFLP) technique, we detected Kras codon 12 muta-tion in 102 formalin-fixed, paraffinernbedded tissuesfrom surgical samples of lung cancer patients. The X ̄2test was used to determine the statistical significance ofdifference, according to the presence or absence of mutation in codon 12 of K-ras oncogene. We found 25 cas-es (24%) positive for mutation of K-ras 12 codon. Mu-tation occured in 6 of the 40 cases (15 %) of squamouscell carcinoma , 18 of 37 adenocarcinoma cases (49%) .1 of 2 adenosquamous cases, 0 of 1 carcinoid patienl ,but no Kras activation was found in small cell carcino-ma (0/22) cases.Analysis of the clinical and pathological features of37 adenocarcinoma cases showed no apparent associa-tions between the Kras codon 12 mutation and sex . dis-ease stage. tumor size (T) , metastatic status (M) andthe degree of differentiation (all P values greater than0.005) . but the nodes (N) of K-ras-positive adenocarci-noma tended to be more than the K-ras-negative ones(P<0. 01) .From 26 male cases of adenocarcinoma mutation incodon 12 of K-ras occur more frequently in adenocarci-noma from smokers than non-smokers (P<0. 05) , sug-gesting that smoking is an important factor in the induc-tion of the mutation.Among 37 adenocarcinoma cases, only 25 cases canbe traced the reeurrence rate in lyear. The 1-year re-currence rates were 85%(11/13) in K-ras mutationalpatients, more than 25%(3/12) in K-ras negative ones(P<0.01) . whereas there was no relationship betweenrecurrence and differentiation in these 25 cases. Thefindings suggest the K-ras gene mutation may be one ofthe prognostic markers for human lung adenocarcinoma.

为探讨基因检测在肺癌中的应用价值,应用PCR-RFLP法检测102例肺癌患者手术标本中K-ras基因第12密码子突变的状况。并将肺腺癌按临床病理特征分组进行对比分析。结果显示,肺癌中总突变率为24%,腺癌中为49%,鳞癌为15%,而小细胞癌中无一例突变。吸烟是促发K-ras基因突变的重要因素(P<0.05),肺腺癌突变组淋巴结转移早、部位远,其一年复发率达85%,明显高于未突变组(P<0.01)。K-ras基因突变的检测具有重要的临床意义和应用价值。

Purpose: To assess the clinical significance of the expression of ras and erbB2 in human lung carcinomas; Method: 40 Tumors from patients with adenocarcinoma (19), squamous cell carcinoma (18), adenosquamous carcinoma (1) and small cell carcinoma (2) of the lung were examined for ras p21 and erbB p185 using immunohistochemical methods. They were divided into groups, contrasted and analysed according their clinicopathologic characteristics. Results: (1)Overexpression of ras p21 erbB p185 were observed in 61% and 42% respectively of non-small cell lung cancer (NSCLC), no positive reaction was found in the two cases of small cell lung cancer (SCLC); (2)The positive rate of p185 in adenocarcinomas showed higher frequencly than that in squamous cell carcinomas (P<0.05); (3)In NSCLC, the positive rate of p21 was 25% in stage Ⅰ~Ⅱ, 77% in stage Ⅲa-Ⅲb, respectively, the difference was significant (P<0.01); (4)In the patients with SNCLC which express p21 and p185, lymph node metastasis was earlier and more rapid (P<0.05); (5)There was sexual difference in expression of p185, incidence of p185 positive staining in females was much higher than that in males (P<0.01). Conclusion: Our findings suggest that the expression of ras and erbB2 in NSCLC is of more clinical signifcanfce.  

目的:了解ras和erbB2基因在肺癌中表达的临床意义。方法:采用免疫组化技术研究了rasp21和erbB2p185在40例肺癌(腺癌19例,鳞癌18例,腺鳞癌1例,小细胞肺癌2例)中的表达,并将肺癌按临床病理特征分组进行对比分析。结果:①在非小细胞肺癌(NSCLC)中,p21的阳性率为61%,p185的阳性率为42%,2例小细胞肺癌(SCLC)均无p21和p185的表达。②p185在肺腺癌中的表达明显高于鳞癌(P<0.05)。③在NSCLC中,p21在Ⅰ~Ⅱ期中的阳性率为25%,Ⅲa~Ⅲb期中的阳性率为77%,两者有非常显著的差异(P<0.01)。④p21和p185阳性的SNCLC患者,其淋巴结转移发生早,速度快(P<0.05)。⑤p185在SNCLC中的表达存在性别差异,女性明显高于男性(P<0.01)。结论:ras和erbB在NSCLC中的表达具有重要的临床意义。
