We collected 22 cultivated population of Lonicera japonica from 17 areas. The characteristics of non-glandular hairs were observed and measured by the scanning electron microscopy. The principal components analysis and correlation analysis were conduct based on length and density of L. japonica. The results showed a significant negative correlation between length and density of non-glandular hairs, and the characteristics of non-glandular was not corrrelated significantly with latitude. The correlation results indicated that the density was a key to separate "Damaohua" and "Jizhuahua". The contribution of climate and soil was important to the cultivated population. This reminded that the characteristics of non-glandular hairs were affected by environmental and genetic interaction.

Sixty-three morphological traits from 743 specimens of the 41 taxa within the cultivated Lonicera japonica were observed and measured, such as the height of plants, the length of leaf, the width of leaf, the length of anther, the alabastrum's number of one branch, the color of alabastrum and so on. A numerical taxonomy is presented by using the cluster analysis, principal components analysis (PCA) and factor analysis. Sixteen of 63 characters were screened by means of PCA and used for cluster analysis of 41 taxa with the method of Ward linkage and average euclidean distance. The cluster analysis showed that the 41 taxa could be divided into 5 groups when the Euclidean distance coefficient was 11.84. The factor analysis indicated that the shape of leaf, color of alabastrum, the pilosity and color of twiggery were of significance for the cultivated L. japonica classification. The results of this study will be a base for the core collection and breeding of L. japonica.

Objective To investigate the association between apolipoprotein J(ApoJ)gene polymorphism and type 2 diabetes mellitus(T2DM).Methods The exons 3、4、7、8 of ApoJ gene were screened by polymerase chain reaction-denaturing gradient gel electrophoresis(PCR-DGGE)in 61 type 2 DM patients and 60 healthy control subjects of Chinese population.Abnormal bands were sequenced.Results The deletion/insertion polymorphism site in exon 7 of the ApoJ gene on two subject groups had significant difference (P0.05).Conclusion ApoJ of exon 7 deletion/insertion polymorphism is one of the genetic marker of 2 DM and the ApoJ polymorphism may be associated with 2 DM.

Objective To investigate the cognition and attitude towards the elderly family nursing among nurses and college students in Chengde, and analyze its influencing factors. Methods A total of 1000 college students and nurses in Chengde were investigated by self-designed questionnaire about their cognition and attitude to elderly family nursing. Results Nurses' cognition and attitude towards the elderly family nursing was better than nursing college students, medical students were better than non-medical students; and there was no statistical significance about their expectation for government's senior citizen service among different groups. Conclusions More attention should be paid to family members' attitudetowards the elderly home care, and should strengthen the elderly family care through various way.

Objective To explore a feasible and effective method of purse-string suture and traction in proce- dures for prolapse and hemorrhoids(PPH)with circular stapler.Methods Width of resected mucosal band and ex- tent of residual hemorrhoid mucosal lifting were compared between two groups of patients with hemorrhoids receiv- ing PPH with“two-point retraction”method(group one,110 cases)and other retraction methods(group two,40 cas- es).Results For group one of 110 cases with“two-point retraetion”,resected mucosal band of all cases were intact and and average width ranged from 3.5 to 5cm.There was a completely residual hemorrhoid mucosal lifting(com- plete return of prolapsed hemorrhoid into the anal canal)in 100 cases of group one(91%).But in group two with other retraction methods,average width of resected mucosal bands ranged from 0.2 to 3.5cm and there was an in- complete band in 10 cases(25%).The rate of mucosal lifting in this group was only 62.5%(19/40).Conclusion Two-point retraction is a feasible,effective and simple method in PPH,resulting in an intact resected mucosal band and sufficient hemorrhoid mucosal lifting.So the two-point retraction PPH is worth to be extended for application.

Objective To investigate the effects of anterior cervical decompression and implanting bone fusion with plate internal fixation under microscope on cervical spondylotic myelopathy. Methods 64 patients were performed anterior cervical decompression and implanting bone fusion with plate internal fixation under microscope. They were assessed with the assessment of Japanese Orthopedic Association (JOA), imageologic and clinical finding 6 months after operation. Results The score of JOA improved from (9.1±2.4) pre-operation to (13.5±3.1) post-operation. Imageologic and clinical features showed satisfactory outcome. Conclusion Most patients with cervical spondylotic myelopathy can achieve satisfied prognosis by decompression through anterior approach; microsurgery.

Through the investigation of Phellodendron Cortex on the market, and 28 batches of samples were collected. By using spectrophotometer the color values of outer surface, inner surface and cross - section of these samples were measured. These measured color data was translated into 3D structure diagram by using the Lab color space tool. The level difference value, the mean value and the threshold value were calculated based the measured color data of these different batches of samples. All 28 groups measured data was analyzed using the methods of Ward linkage and average Euclidean distance. At the same time, we invited Professor Jin Shiyuan, the "Chinese medicine master", to identify, quality-evaluate and grade these 28 batches of Phellodendron Cortex samples base on the traditional experience, then compared the traditional empirical results with the spectrophotometer measurement results. The result showed that, the Phellodendron Cortex could be divided into Phellodendri Amurensis Cortex and Phellodendri Chinensis Cortex by color numerical clustering, and classified according to quality. The classification result has a high degree of consistency with the traditional experience.

BACKGROUND:There are few reports concerning effects of warming the yang and benefiting the marrow for the knee osteoarthritis on the expression of matrix metal oproteinase.
OBJECTIVE:To observe the effect of warming the yang and benefiting the marrow on the expression of matrix metal oproteinase in rabbit models of knee osteoarthritis.
METHODS:Of 96 healthy adult New Zealand rabbits, 72 rabbits were randomly selected for making rabbit models of knee osteoarthritis using plaster external fixation. After success model establishment, the rabbits were randomly assigned to three groups. Model group was left intact. Chinese medicine group received daily intragastric administration of drug extract 24 mL/kg. Drug control group was daily intragastrical y administered Puli Capsule (glucosamine hydrochloride) 24 mg/kg, once a day, until the eighth week of success model induction. An additional 24 New Zealand rabbits served as blank controls.
RESULTS AND CONCLUSION:Using quantitative PCR, matrix metal oproteinase-1, matrix metal oproteinase-3 and matrix metal oproteinase-13 expression was significantly higher in the model group than that in the other three groups. Matrix metal oproteinase-1, matrix metal oproteinase-3 and matrix metal oproteinase-13 expression was significantly lower in the Chinese medicine group and drug control group than that in the model group. These results indicated that warming the yang and benefiting the marrow for knee osteoarthritis in rabbits could effectively inhibit the expression of matrix metal oproteinase in rabbits.
