As a common and frequently-occurring disease,glenohumeral instability is become one of disease which restrict upper limb activity. The diagnosis of this disease is easy, but it is very difficult to assess the degree of periarticular soft tissue injuries. With the development of magnetic resonance imaging and arthroscopy, MRA become the gold standard for evaluation of glenoid labrum, joint capsule and ligaments injury. The traditional manual reduction is a fast, simple method, but often can cause adverse consequences,such as rotator cuff tear,ligament relaxation,and habitual dislocation. Open operation can rebuild stability of joint,but with many new treatment methods,especially the arthroscopic reconstruction has gradually replaced the open operation, and become the mainstream trend, but for the long-term effect of capsular tightening surgery, rotator cuff gap closure is not clear,it is need further follow-up observation.

Objective To observe the effects of Tongyang Huoxue Recipe on cytoskeleton proteinβ-tubulin of ischemia reperfusion injured sinoatrial node cell in rabbits;To discuss its mechanisms in the treatment of sick sinus syndrome. Methods Sinoatrial node cells were obtained from newborn rabbit. Oxygen and glucose were deprived to simulate ischemia and were restored to simulate reperfusion. Cells were divided into 5 groups. Tongyang Huoxue Recipe high-, medium-, low dose groups were given corresponding medicine (final concentrations of 100, 20, 10 μg/mL). The normal group and model group were given equal volume of culture medium. Enzyme mark instrument and laser scanning confocal microscopy were used to observe the sinoatrial node cell activity and cytoskeleton protein β-tubulin of each group. Results Living cells of model group decreased significantly compared with normal group (P<0.01), and cytoskeleton proteinβ-tubulin cleavage significantly. Living cells of Tongyang Huoxue Recipe high, medium and low dose group were significantly higher than those in the model group (P<0.05), and β-tubulin structure remained more complete than the model group. Conclusion Tongyang Huoxue Recipe can inhibit the injury induced by ischemia reperfusion of sinoatrial node cells;the possible mechanism of Tongyang Huoxue Recipe in treating sick sinus syndrome is protecting activity and cytoskeleton proteinβ-tubulin of sinoatrial node cells.

Nano-materials are immensely applied in piezoelectric, electrochemical, optical, magnetic biosensors based on clearly unique nature of it. The important role of nano-materials in biosensors is expounded and the latest application of novel functional nano -materials in biosensor is introduced emphatically, such as nanoparticles, nanotubes, nanowires, quantum dots and nanofibers. The researches make clear that nano-materials can provide momentous value in enhancing performance of biosensors, such as sensitivity, detection range, and repetitiveness of biosensors, as immobilization materials or carriers.

Objective To evaluate the efficacy of supportive psychotherapy on patients with cardiac neurosis. Method 32 patients with cardiac neurosis were treated with a comprehensive measure consists of adequate drug therapy and supportive psychotherapy. Symptom Checklist 90 (SCL - 90) was rated. Result Among the 9 factors of SCL - 90, scores of somatization, obsessive - compulsive, interpersonal relationship, depression, anxiety and phobic anxiety factors were significanly higher than that of normal controls. After treatment, the scores of somatization, depression, anxiety and phobic anxiety were statistically reduced. Patient- reported improvement efficacy was 84. 38%.Conclusion Adequate drug therapy together with supportive psychotherapy has reliable efficacy on patients with cardiac neurosis.

Safety assessment in clinical trials is dependent on an in-depth analysis of the adverse events to a great extent. However, there are difficulties in summary classification, data management and statistical analysis of the adverse events because of the different expressions on the same adverse events caused by regional, linguistic, ethnic, cultural and other differences. In order to ensure the normative expressions, it's necessary to standardize the terms in recording the adverse events. MedDRA (medical dictionary for regulatory activities) has been widely recommended and applied in the world as a powerful support for the adverse events reporting in clinical trials. In this paper, the development history, applicable scope, hierarchy structure, encoding term selection and standardized query strategies of the MedDRA is introduced. Furthermore, the practical process of adverse events encoding with MedDRA is proposed. Finally, the framework of statistical analysis about adverse events is discussed.

AIM: To establish an HPLC-MS for determining seven bioactive components,including vanillin ferulaic acid,ligustrazine,senkyunolid I,H,and A,and ligustilide in Ligusticum chuanxiong Hort. . METHODS: The bioactive components were extracted by ultrasonic method,and then were separated by reverse HPLC,and finally were determined by the multiple reaction mode of MS. RESULTS: The detected limits of the seven bioactive components such as vanillin were 40,20,80,20,10,60 and 50 ng/mL,respectively. Their linear range were 1450,4-490,1-625,2-360,2-700,1-244 and 21-210 ?g/mL,respectively. The average contents of the above components in Ligusticum chuanxiong Hort. were 0. 12,0. 25,0. 41,0. 99,0. 30,8. 96 and 11. 25 mg/g,respectively. CONCLUSION: The proposed method has the characteristic of simplicity,rapidty and high sensitivity. It could be used in analyzing the whole components of Ligusticum chuanxiong Hort. .

ObjectiveTo observe the effects of catalpol, the effective component of Rehmanniae Radix, on atrionector cell apoptosis andβ-tubulin in vitro rabbit injured by simulated ischemia reperfusion;To explore the mechanism of treating sick sinus syndrome.MethodsAtrionector cells were collected from newborn rabbits. Cells were divided into 5 groups:normal group, model group, catalpol high, medium and low dose groups. Anoxia and aglycaemia were established to simulate ischemia. Atrionector cellular damage models were established by recovering the supply of oxygen and sugar. Normal control group and model group were given the same volume of culture medium, while catalpol high, medium and low dose groups were given medicine with relevant concentrations (100, 20, 10μg/mL, respectively). ELISA, FCM, laser scanning confocal microscopy were used to observe apoptosis rate andβ-tubulin of atrionector in each group.Results Apoptosis rate of the model group was obviously higher than the normal group (P<0.01), andβ-tubulin cleavage was obvious. Apoptosis rate in catalpol high, medium and low dose groups were significantly lower than that of the model group (P<0.01);β-tubulin structure were significantly more complete compared with the model group;the fluorescence intensity was significantly higher than that of model group (P<0.01).Conclusion Catalpol can inhibit atrionector cellular apoptosis caused by simulated ischemia reperfusion. Its protective effects on atrionectorβ-tubulin may be the mechanism of the treatment of Rehmanniae Radix for sick sinus syndrome.

Objective To observe the effects of ferulic acid on cell apoptosis andβ-tubulinin vitro of rabbit sinoatrial node injured by hypoxia and low glucose, and to explore its mechanism.Methods Model cells were established on sinoatrial node cells from newborn rabbit by performing deprivation of oxygen and glucose. Then the model cells were divided into 5 groups: a normal control group, a model group, ferulic acid high, medium and low dose group. The normal control group and the model group were treated with equal volume of culture medium, and the three volume ferulic acid groups were treated with ferulic acid of 100, 20, and 10μg/ml respectively. Flow cytometry, laser scanning confocal microscopy were used to observe the sinoatrial node apoptosis rate and cytoskeleton proteinβ-tubulin in each group.Results Apoptosis rate of the model group was obviously higher than the normal group (56.95% ± 11.99%vs. 31.45% ± 6.32%,P<0.01), whileβ-tubulin cleavage was significantly lower than the normal group (5.141 ± 0.218vs. 8.035 ± 0.762,P<0.01). Apoptosis rate of ferulic acid high, medium dose group were significantly lower than the model group (24.85% ± 6.34%, 26.70% ± 9.84%vs. 56.95% ± 11.99%,P<0.01),β-tubulin structure were significantly more complete compared with the model group (7.927 ± 0.357, 5.961 ± 0.351vs. 5.141 ± 0.218,P<0.01).Conclusions Ferulic acid can suppress apoptosis of sinoatrial node cells caused by low glucose and oxygen. Protecting the sinoatrial node cell skeleton protein ofβ-tubulin may be one of the mechanisms.
