While tracing back the 50 years of history and achievements in higher education of TCM,it compares it with western medicine,and sets up 3 elements(research object,knowledge system and intellectual producing style)scale for a separate discipline.Chinese medicine development is slow and weak;therefore it expounds the self-enhancement path from adjusting key Chinese medicine development points,strengthening the idea of paddling its own canoe,perfecting knowledge system and improving the academic and scholar level of Chinese medicine team.

The geo-herbalism of Cangzhu, Atractylodes lancea (Thunb.) DC. , was studied for itsstrict quality control. Samples of typical and representative populations of geo-herbal and non-geo herbalorigin were collected, examined and cultivated through field work. Volatile oils from samples of varioushabitats were determined by GC/MS, and their respective bacteriostatic minimum inhibitory concentration(MIC)determined. Results of the study showed that both the size of capitulum and cleft on the leaves var-ied greatly even in species of the same population. The main components in their volatile oil also variedgreatly with Maocangzhu (MCZ) contains atractylone (29.54%) and atractylodin (17.82%); that of Nan-cangzhu (NCZ) contains hinesol (61.86%) and β-eudesmol (19.79%), and Baicangzhu (BCZ) cantains βeudesmol or mixture of β-eudesmol and atractylone (over 30%). Volatile oils of speciaes from Luotina,Taibai, and Huanglong showed potent bacteriostatic activity against Streptococcus hemolyticus (SH), com-parable to penicillin or streptomycin. In conclusion, A. lancea is a polymorphic complex greatly influencedby geographic environment and a reasonable proposal is to name them by geo-herbal names such as: MCZas A. lancea var. maoshanensis Hu et Feng; NCZ as A. lancea subsp. luotianensis Hu et Feng; and BCZ asA. lancea var. chinensis (Bunge) Kitam other than independent species as A. chinensis Bunge. It was in-correct to say that MCZ has no atractylone in its volatile oil and therefore differs from A. macrocephalaKoidz. (Baizhu). Inhibitory activity of the volatile oils against SH and Pseudomonas aeruginosa (PA) arealso quite different due to the habitats and imply that the rhizome from Luotian may be used to cure infec-tion diseases caused by SH and PA besides their traditional uses.

Objective To prepare TF conjugated doxorubicin and Rg 3 loaded liposome and evaluate their properties and effect on the treatment of gastric cancer. Method The liposomes were prepared by thin iflm hydration method. The efifciency of cellular uptake on MKN-28 cells in vitro was evaluated. The anti-proliferation efifciency of TF-LP-DOX/Rg 3 was evaluated by MTT assay. Tumor spheroids were used to evaluate anti-tumor ability of TF-LP-DOX/Rg 3. Results The result demonstrated that TF-LP uptaken by MKN-28 were 2.9 times higher than that of LP(P<0.01). The MTT assay and the inhibition of tumor spheroids in vitro conifrmed strong inhibitory effect of TF-LP-DOX/Rg 3. Conclusion TF-LP-DOX/Rg 3 easily prepared and it is a potential delivery system for the treatment of gastric cancer.

Objective To investigate the frequency of micresatellite instability (MSI) and loss of heterozygosity (LOH) and select sensitive loci for studying microsatellite DNA imbalance in thymic squamous cell carcinoma. Methods 5 microsat-ellitc polymorphism markers and extrated DNA were selected from 9 specmiens of paired thymie squamous cell carcinoma/nor-real tissues. MSI and LOH in the specmiens of thymic carcinoma and relevant pericancerou tissues were detected by polymerase chain reaction (PCR) followed by 6% polyacrylamide gel electrophoresis(PAGE) with silver staining. Results MSI or LOH was detected in 9 thymic carcinoma tissues. The frequency of MSI or LOH was 66.7% (6/9) at loci of D6S1708, 33.3% (3/9) at TP53, 33.3% (3/9)at DM, 33.3% (3/9)at D11S988 and 0% (0/9)at D8S136, LOH at D6S1708 (5/6) was a common genetic alteration. DI1S988 had only LOH alteration. Conclusion D6S1708, TP53, DM, and D11S988 are sensi-tive loci for studying microsatellite DNA imbalance in thymic squamous cell carcinoma. Microsatellite DNA imbalance may play a certain role in occurrence and development of thymic squamous cell carcinoma, and the relationship between MSi or LOH.The linicopathological features of thymic squamous cell carcinoma needs further investigation.

Objective To explore the joints and tendons characteristic features of high frequency ultrasound in asymptomatic hyperuricemia(AH) and to assess its value in AH diagnosis.Methods One hundred asymptomatic individuals with hyperuricemia (AH group) and 75 normouricemic subjects (control group) were examined by high frequency and color Doppler ultrasound.The joints,tendons and soft tissue of the knees,ankles and first metatarsal-phalangeal joints in two groups were examined.The correlations of serum urate(SU) level with double contour sign,bone erosion and articular cavity effusion were analysed.Results Hyperechoic deposition on the sulface of the articular hyaline cartilage (double contour sign) were found in the knees (35),ankles (17) and the first metatarsophalangeal joints (MTPJs,48) from the asymptomatic individuals with hyperuricemia,in contrast to none in the control group (P ＜0.05).Similar results were found in two groups of the bone erosion (30,25,20 vs 4,6,3,P ＜0.05),the effusion (28,36,41 vs 6,8,9,P ＜0.05) and the hyperechoic spots (19,18,22 vs 0,0,0,P ＜0.05).Patellar enthesopathy (4.5％ vs 0.6％,P ＜0.05) as well as achilles enthesopathy(8％ vs 0,P ＜0.05) and achilles tophi (6％ vs 0.6％,P ＜ 0.05) were more frequent in asymptomatic hyperuricemic than that of normouricemic individuals.No correlations between SU concentration and the presence of the double contour sign,the bone erosion and effusion were found (P ＞0.05).Conclusions There were some similar specific sonographic findings of gouty arthritis in the asymptomatic individuals with hyperuricemia.Also,these findings support high frequency ultrasound as a useful tool to detect anatomical damage in the joints,synovial tissue and tendons of asymptomatic individuals with hyperuricemia.

Objective To explore the function of serum myocardial enzymes on bronchiolitis disease with myocarditis in clinical diagnosis. Methods 91 children with bronchiolitis were hospitalized and 40 cases of the same period of non-infectious disease test results of serum myocardial enzymes were analyzed. Results In the test results of serum myocardial enzymes from 91 cases of bronchiolitis disease, the abnormal rate of Valley-Grass aminotransferase (AST) was 68.13%; the abnormal rate of creatine kinase isoenzyme (CK-MB) was 67.03%; the abnormal rate of lactate dehydrogenase(LDH) was 56.04% ;the abnormal rate of creatine kinase(CK) was 32.97%. Compared with the control group,CK-MB,AST,LDH,CK were significantly higher(P＜0.01). Conclusion For thechildren with bronchiolitis disease,myocardial damage should be alerted and early detection of myocardial enzymes should be taken.

Object To develop a new method of discriminating the principle components of Radix Paeoniae Rubra (RPR) from different areas, and to find the reason for forming high-quality of RPR in the place of the genuine. Methods Using Foruier transform infrared (FTIR) absorption spectrometry, the characteristic peaks of fingerprint infrared spectra of RPR samples from 18 habitats were recognized and compared. Results Frequency, intensity and shape of infrared absorption spectra were obviously different between wild and cultivated groups of RPR. The infrared absorption peaks of RPR in Duolun, a famous Chinese orthodox drug, were of distinct characteristics. Conclusion FTIR technique is first applied to rapid analysis of principle component of RPR from different areas. So an operable method in the quality control and discrimination of RPR in the place of the genuine is provided.

Objective To investigate the effect of Terpinen-4-ol on the proliferation of lung adenocarcinoma A-549 cells and its related mechanism. Methods A-549 cells were treated with different concentrations of Terpinen-4-ol. The inhibitory effect of Terpinen-4-ol on A-549 cells was tested by MTT method. Cell grow ability was determined by CCK-8 colorimetry. The ultrastructure of A549 cells were observed by transmission electron microscopy before and after Terpinen-4-ol treatment. The changes of cell cycle, apoptosis, and the level of intracel-lular calcium were inspected by flow cytometry. Inoculated the lung adenocarcinoma A-549 cells on the nude mice to form transplantation tumor. The experimental nude mice with transplantation tumors were divided into three groups:negative control group,high dose positive con-trol group and low dose positive control group. The mice were given continuously intraperitoneal injection for 10 days, and then the transplan-tation tumors were taken and the size and weight of them were detected. Results After Terpinen-4-ol treatment for 24 h,MTT assay showed that the IC50 value of A549 cells was 0. 067% v/v. The growth curves of positive control groups were significantly smooth than the negative control group. The formation of autophagosome increased after treatment with Terpinen-4-ol. The results of flow cytometry showed that the cell cycle was arrested in S phase,Terpinen-4-ol could induce apoptosis of A549 cell, The intracellular calcium concentrations in positive control groups were significantly higher than the negative control group(P<0. 05). Low dose group and high dose group restrained the growth of the transplantation tumor obviously, and the tumor inhibitory rate were 53. 33% and 77. 76% respectively. Conclusion Terpinen-4-ol has inhibitory effect on the proliferation of A-549 cells in vitro and in vivo.

Objective To measure the reconstructed cranial CT images,and to clarify the safety range of unilateral nasal transsphenoidal approach for pituitary surgery.Methods 100 normal pituitary cranial CT images were randomly selected,and the three-dimensional reconstruction was performed by using the CT images of perpendicular and parallel to the edge of the two eyes as base line, and the distance and angle in unilateral nasal transsphenoidal approach for pituitary surgery from the sagittal plane in the middle of the nasal meatus and the plane through the tip of the nose and both ends of dorsum sellae were measured,respectively.
