The targets of establishing the alliance is to provide on-line cooperative catalogue, documents exchange and OPAC (online public access catalog), the prescription of the alliance construction, and the latest trend of the alliance. The paper also explored the policy for constructing library alliaqce and put forward the developing treads of this alliance.

As a new radiotherapy for carcinomas, Proton Therapy has been making progresses. Compared with conventional radiation, proton has a better physical characteristic and a similar biological effect. Proton Therapy consists of Conformal Proton Radiotherapy, Intensity-Modulated Proton Therapy, Stereotactic Radiotherapy, Proton Scanning Radiation and et al. With the utilization of Bragg peak, Proton therapy can increase the dose of carcinoma region and reduce the dose of normal tissue, and thus it has a good curative effect and can be a good cure for many indications. In spite of the above-mentioned, Proton therapy has to be improved in the future.

Objective To analyze the clinical data,radiological and pathological features of breast cancer which were understated by image,and summarize the causes.Methods The clinical features,radiological features and pathological data of 26 cases of breast cancer were retrospectively analyzed.The preoperative ultrasound and mammography BI-RADS grades of these 26 cases were both ≤ 3,and they were confirmed to be breast cancer by pathology.The clinical and pathological data of 1224 cases of breast cancer in the same period were compared.Results For the 26 cases,100％ were early breast cancer,100％ were HER2 negative breast cancer,and only 1 case had lymph node metastasis.26％ were special type of breast cancer.Mammography showed glandular multi type,and ultrasound showed atypical or typical benign features.Conclusions Breast cancer understated by image shows features of young age,early stage,well differentiated,low malignant degree,not easy to be visualized by mammography,and their ultrasound features are usually atypical.In clinical setting,analysis of the ultrasound and mammography images should be combined with other examination,to decrease misdiagnosis rate.

ResultsTranslational medicine has been successfully introduced into the realm of TCM applications and researches. ConclusionThe rise of translational medicine will promote the development of Chinese medicine and provide better opportunities for innovation.

The establishment of overseas traditional Chinese medical book database provides a new approach to help Chinese medical researchers to catch on the overseas Chinese medicine development. Overseas traditional Chinese medical book database is introduced and the overseas development of Chinese medicine has been discussed by using statistic results from the database in this paper.

Objective This study is to explore the infratentoriat-supracerebellar keyhole approach for microsurgical treatment of pineal region tumors and to evaluate its curative efficacy and safety.Methods According to hi-fi quality MRI images,individual operation schemes were designed.Microsurgical infratentori- al-supracerebellar keyhole approach was used to resect lesions in 7 consecutive patients with prone postition.A 2.0 cm?2.5 cm surgical bone window was performed with its superior margin reaching to the inferior margin of the transverse sinus and confluence sinus.Results Among the 7 pineal region tumors,there were 2 ger- minomas,2 pineocytomas,1 pineoblastoma,1 glioma and 1 chlesteatoma.All cases were re-examined with MRI after operation and it was found that 6 lesions were totally removed and 1 was subtotally removed.The outcome of the treatment was satisfying.There was no infection,bleeding or death after surgery.The follow-up result in the near future was good.Conclusion The infratentorial-supracerebellar keyhole approach for the excision of pineal region tumors was proved to be a satisfactory means with a total removal rate,an excellent curative effect and small surgical trauma.

Objective: To analyze the correlation of carotid artery color Doppler flow imaging (CDFI) indices and transcranial Doppler ultrasound (TCD) indices. Methods: The clinical data of 118 hospitalized patients with ischemic cerebrovascular diseases were included in the present study and all of them received CDFI and TCD examination. The patients were divided into two groups according to presence of carotid plaque group; t-test was used to identify the correlation between the presence of carotid plaque and TCD indices. Meanwhile, the patients were also divided into three groups according to the quantity/distribution of plaque) one-way ANOVA(F-test) and student-Newman-Keuls were used to identify the correlation of the quantity/distribution of plaque with TCD indices. The patients with carotid plaque were divided into three groups according to the plaque texture) one-way ANOVA(F-test) and student-Newman-Keuls were used to identify the correlation of the quality of plaque with TCD indices. Meanwhile, linear correlation was used to identify the correlation of the common carotid intimal-medial thickness (CCA IMT) with TCD indices. Results: The resistance index (RI), pulsatile index (PI) and ratio of peak systolic to least diastolic flow velocity (S/D) of bilateral middle cerebral arteries and basal artery in patients with carotid plaque were significantly higher than those in patients without carotid plaque (P<0.05); other TCD indices including Vp, Vd, and Vm were not significantly different. The quantity/distribution of plaque, the quality of plaque and CCA IMT were not correlated with TCD indices. Conclusion: No CDFI indices, except for the presence of carotid plaque, are correlated with TCD indices. Combined application of CDFI and TCD indices can better reflect the structure and hemodynamic status of cerebral vessels.

X-ray plane film. Three-dimensional CT could show the three-dimensional structure of spinal canal clearly. The postoperative efficacy of all patients was satisfactory. Conclusion The three checking methods of spinal fracture were complementary to each other, but three-dimensional CT had the advantage in reconstructing spinal canal.

To study the effects of fractioned ir radiation on the total RNA and MDR 1 mRNA of NCI H 446 small cell lung cancer cell line, NCI H446 cells in the period of exponential growth were exposed to 60 Co ? radiation at 2 Gy/fraction, 2 fraction/week, with the cumulative dose of 50 Gy by 25 fractions. The total RNA of the cells of the irradiated group and control group were extracted by the acid guanidine thiocyanate phenol chloroform method and the amount of the expression of MDR 1 mRNA was assessed by qualitative RT PCR assays. Under the conditions of same cell number and volume, in cells of the control group, the concentration of the total RNA was 25 9 ?g/ml and the ratio of MDR 1 DNA/? actinDNA was 1 078, whereas in cells of the irradiation group, the corresponding values were 16 6 ?g/ml and 1 338, respectively. It is concluded that, for the NCI H446 small cell lung cancer cell line, a high dose accumulated during fractioned irradiation can inhibit the synthesis of its total RNA and enhance the expression of its MDR 1 gene at the same time.

This paper is aimed to explore the correlation of clinical outcomes with material science features of implant in the treatment of atlantoaxial instability by the Vertex technique.A total of 26 cases with atlantoaxial instability and dislocation were enrolled from the Affiliated Hospital of Luzhou Medical College between January 2004 and January 2006.They all underwent the internal fixation via posterior cervical pathway and atlantoaxial fusion in Vertex system that was produced by American Sofamor Danek Company.The intraoperative complications and postoperative neurological recovery of each case were documented.Dynamic radiograph and digital tomography were used to evaluate the extent of the atlantoaxial vertebrae stability.①The result of X-ray showed that bony fusion was successful in 22 patients during 3-month follow-ups,3 patients during 6-month follow-ups,and 1 case after implantation following bony resorption.②There was no deterioration of spinal cord injury and the JOA scores of neurofunction increased from 3-17 points(mean 6.8 points) to 5-17 points(mean 14.8 points) ,with the rate of improvement as 83%.③All 26 patients were normal in the movements of expansion and flexion,but the rotation was partly limited.There were 18 cases rotate in 120?,6 cases in 100? and 1 case in 60?.Vertex system is effective in dealing with internal fixation via posterior cervical pathway.Due to the connection with stick by multiaxial screw,Vertex system presents superiority in clinic,such as secure fixation,random length and convenient connection.Vertex system internal fixation is effective in dealing with atlantoaxial instability and dislocation.
