ObjectiveTo analyze the different effects of spiral progress method and traditional method used in computer teaching in TCM colleges and universities.MethodsStudents were divided into the groups of spiral and traditional. At the end of the course, students would have a course examination.Results Students in spiral group got better scores than students in traditional group (P<0.05).Conclusion Using spiral progress method in computer teaching in TCM colleges and universities can help students develop the right thinking model and scientific learning method. It can also improve students’ ability to use computer knowledge in TCM study and research.

Objective To explore the pathogenesis of femoral head ischemic necrosis(FHIN),and to observe the clinical therapeutic effects of extracorporeal shock waves therapy(ESWT) for FHIN in soldiers.Methods With exclusion of the femoral head necrosis sAbsequent to femoral neck fracture,108 cases of FHIN in ARCO stage Ⅰ-Ⅲ period,induding 86 males and 22 females,with aged ranged from 17 to 25 years,were involved in the present study,and the treatment modality was chosen by patients voluntarily.In 50 patients,ESWT combined with drilling decompression procedure(ESWT group) was chosen,and 9-12kV(0.16-0.22mJ/mm2) of extracorporeal shock wave was applied on the second day after drilling decompression.X-ray and MRI of bilateral hip joints were taken and Harris hip score(HHS) was estimated at 6 and 12 months after treatment.58 patients chose the treatment of simple drilling decompression served as controls.The results of the two groups were analyzed by Student's paired t test.Results No aggravation of FHIN occurred in the two groups.The average ratio of necrosis zone in ESWT group was diminished by 22.9%,32.8% and 34.3%,respectively,in the stages of ARCO Ⅰ,Ⅱ and Ⅲ,and the improvement was better in ARCO Ⅱ and Ⅲ stages than that in control group(P

Objective To study the effect of extracorporeal shock wave therapy with percutaneous autogenous bone marrow grafting in the mannagement of long bone nonunion.Methods After success in marrow aspiration from patients' iliac crest,19 cases of patients accepted the treatment of bone marrow grafting and ESWT.Then,it's therapeutic effect was compared with 23 cases of single ESWT group,such as average rate of bone union and average healing time during follow-up period.The data of this study was analyzed by independent-samples t test,and a P value of

“Mechanical memory” approach was commonly used in the knowledge learning of traditional Chinese medicine, which makes students often feel that the knowledge is too abstract, and this method is thus ineffective. “Qihuang the way” using Unity 3D game development platform inte-grates the elements of medical knowledge of the Chinese medical history, and combines TCM theoretical knowledge learning with serious games , which can help invoke students' enthusiasm and improve learning efficiency in an entertaining way.

BACKGROUND:No method is ideal for treating traumatic avascular necrosis of talus up to now.Extracorporeal shock wave therapy(ESWT)is a micro-traumatic,simple,and effective method to treat musculoskeletal diseases;however,the therapeutic effect on necrosis of talus needs to be further studied.OBJECTIVE:To evaluate the therapeutic effect of liquid-electric extracorporeal shock wave on traumatic avascular necrosis of talus,and to explore new treatments of traumatic avascular necrosis of talus METHODS:A total of 34 patients with traumatic avascular necrosis of talus were selected from the Affiliated Hospital of Medical College of Chinese Armed Police Force from September 2004 to June 2009.The patients were randomly divided into ESWT and control groups,with 17 patients per group All patients were treated with pain point positioning combined with surface X-ray localization,theworking voltage of 8-10 kV,energyflowdensity of 0.12-0.16mJ/mm2,impact frequency of 40-50 times/min,and impact of 800-1000 times,once a week,for 3-5 cycles.Pain was evaluated with VAS before and after treatment,function of ankle was evaluated with AOFAS standards,and MRI of ankle was re-checked at 18 months after treatment to compare necrotic area before and after treatment.RESULTS AND CONCLUSION:VAS pain,function of ankle,and necrotic area of ankle in the ESWT group were significantly improved compared to those in the control group at 18 months after treatment(P<0.01).Activity of one case in the control group was limited by severe pain due to traumatic arthritis in the first 15 weeks after ankle arthrodesis surgery.This suggested that significant effect and fewer complications,for treating traumatic avascular necrosis of talus.

Objective To investigate the research status of domestic TCM systems biology in recent ten years, and provide reference for further research. Methods TCM systems biology literatures published in domestic journal were retrieved and screened. The data were analyzed from the annual distribution, regional distribution, research institutions, source journals, research fields, and so on. Results The total literature of TCM systems biology showed an increasing tendency. The research mainly distributed in TCM chemical matteromics, TCM genomics, TCM proteomics, TCM metabolomics, and TCM informatics. Beijing, Guangdong and Shanghai were in the leading position. Conclusion The development trend of domestic study on TCM systems biology is rising year by year, and the understanding of the subject is continuously improving.

Object The mineralogical and chemical compositions of the natural pharmaceutical montmorillonite clay were analysed with the aim of approaching the material base of its action Methods The means of X ray diffraction (SRD) and X ray fluorescence (SRF) were used for the quantitative analysis of the mineralogical and chemical compositions of the montmorillonite clay samples Results The essential mineralogical and chemical compositions of the six samples were obtained Conclusion Though there is some difference in mineralogical composition of the montmorillonite clay samples from different deposits, the average percentage of montmorillonite content in samples is 86%, and the chemical compositions of six samples are nearly similar

BACKGROUND:Chondromodulin-Ⅰ is expressed mainly in the cartilage, but it is little expressed in mesenchymal stem cells. Combined with the previous study of our group, we concluded that chondromodulin-Ⅰmaybe play an important role in inducing mesenchymal stem cells into chondrocytes accurately.
OBJECTIVE:To construct an expression plasmid stably carrying chondromodulin-Ⅰ to up-regulate the expression of chondromodulin-Ⅰ in bone marrow mesenchymal stem cells.
METHODS:Specific primers were designed in rat cartilage for chondromodulin-Ⅰ gene, then the pcDNA3.1 (+) plasmid expression vector was digested by enzyme and directional connected gene to construct pcDNA3.1(+)/ChM-Ⅰ expression vector. Bone marrow mesenchymal stem cells were obtained from rats using the method of density gradient centrifugation combined with adherent culture. Recombinant plasmid pcDNA3.1(+)/ChM-Ⅰ was transfected into rat bone marrow mesenchymal stem cells with liposome method, and G418 selection was used for stable screen of transfected cells. Reverse transcription-PCR and western blot were used to detect chondromodulin-Ⅰ expression in celllines.
RESULTS AND CONCLUSION:The positive clones were digested by enzyme and were identified and sequenced. The results showed that the reality length and sequence of chondromodulin-Ⅰ gene were consistent with the theoretical values, and reading frame was correct. Reverse transcription-PCR and western blot results showed that the expressions of chondromodulin-ⅠmRNA and protein were markedly up-regulated in bone marrow mesenchymal stem cells. Recombinant plasmid pcDNA3.1(+)/ChM-I was successful y constructed, and transfected into rat bone marrow mesenchymal stem cells. After G418 selection, expression of chondromodulin-Ⅰ was up-regulated stably in rat bone marrow mesenchymal stem cells.

OBJECTIVE:To provide identification reference for the clinical use of Cinnabaris. METHODS:TCM micro-macro-scopical identification method and microscopic identification method were used. RESULTS:The micro-macroscopical characteristics were obtained:irregular granule or sheet block,different forms,wide bright red,opuque translucent with some luster; some sam-ples showed irregular lump with big shape,red scale on surface,dulling or gray-black. The were microscopic characteristics ob-tained:different forms of irregular granule,some sheet block,wide bright red,with some luster,occasionally with yellow gran-ules. CONCLUSIONS:The method for micro-macroscopical identification and microscopic identification of Cinnabaris is simple and convenient,and it can be used for the rapid verification of Cinnabaris.
