There are some common problems such as recurrent symptoms and poor compliance among patients with chronic diseases. Although scientific knowledge and skills have been learned from traditional health education, patients with chronic diseases cannot improve their life style continuously. At present, many researches abroad have proved that health coaching contributes to setting feasible goals and encourages continuously behavior change of patients. In China, health coaching is in the stage of becoming familiar with its scientific definition, intervention effect and application characteristics. And health coaching also needs evidences from high-level evidence-based studies. Along with continuous improvement of intervention techniques on health management, health coaching will get further development and standardization.

In vivo imaging system (IVIS) is a new and rapidly expanding technology, which has a wide range of applications in life science such as cell tracing. By counting the number of photons emitted from a specimen, IVIS can quantify biological events such as tumor growth. We used B16F10-luc-G5 tumor cells and 20 Babl/C mice injected subcutaneously with B16F10-luc-G5 tumor cells (1x10(6) in 100 muL) to develop a method to quantitatively analyze cells traced by IVIS in vitro and in vivo, respectively. The results showed a strong correlation between the number of tumor cells and the intensity of bioluminescence signal (R (2)=0.99) under different exposure conditions in in vitro assay. The results derived from the in vivo experiments showed that tumor luminescence was observed in all mice by IVIS at all days, and there was significant difference (P<0.01) between every two days from day 3 to day 14. Moreover, tumor dynamic morphology could be monitored by IVIS when it was invisible. There was a strong correlation between tumor volume and bioluminescence signal (R (2)=0.97) by IVIS. In summary, we demonstrated a way to accurately carry out the quantitative analysis of cells using IVIS both in vitro and in vivo. The data indicate that IVIS can be used as an effective and quantitative method for cell tracing both in vitro and in vivo.

Objective To study the appearance of magnetic resonance imaging (MRI) in early stages of cartilage degeneration and to detect its values.Methods Intra articular injection of 5 units of papain causing a reversible loss of cartilage proteoglycan in the New Zealand rabbit knees.Rabbits were scanned with magnetic resonance imaging,using a 0 3 T Hitachi magnet with 16 cm coil.Gradient echo sequences and spin echo sequences were performed in the sagittal planes at 0,24,48 and 72 hours after intra injection of papain.Then signal intensity and thickness of cartilage were measured.The proteoglycan content was measured biochemically and histochemically.Results The cartilage thickness and signal intensity decreased significantly in treated knees compared with control knees at 24 and 48 hours ( P 0 05) after injection of papain.These changes on magenetic resonance (MR) images were consistent with the changes of proteoglycan concentration measured by biochemical analysis and histochemical staining of cartilage.Conclusion It is possible for MRI to detect the early stages of cartilage degeneration.

Besides theessentialrehabilitation treatment, the treatment group was intervened by muscle-region alignment needling plus dermal needle therapy, while the control group was given regular Western medication.Thetwo groups were intervened for 3 weeks and were followed up for 6 months. The neurologic function, Functional Comprehensive Assessment (FCA), and Stroke Speciality-Quality of Life (SS-QOL) were observed for the follow-up study.ResultThe total effective rate was 93.4% in the treatment group versus 61.5% in the control group, and the difference was statistically significant (P<0.05); the neurologic function, FCA score, and SS-QOL score in the treatment group were significantly superior to that in the control group at the end of the follow-up study (P<0.05).ConclusionMuscle-region alignment needling plus dermal needle therapycan produce a content long-term therapeutic efficacy in treating post-stroke upper-limb spasticity.

Objective:Our aim was to study the levels of atrial natriuretic peptide (ANP) and pulmonary perfusion imaging in determining of pulmonary artery hypertension (PAH). Methods: We measured ANP levels by using radioimmunoassay after making various types of PAH in rabbits. Catheterization and pulmonary perfusion tomographic imaging were used in the control group. Results: When the pulmonary artery pressure increased slightly, the ANP levels were lower in PAH group than that of control group, but the difference was not significant (t=1, P>0.05). At the same time, pressure measured by catheterization did not change as the control group, but the ratio of back/abdomen radiopharmaceuticals distribution which was measured with pulmonary perfusion tomographic imaging was significantly higher in PAH group than that of the control (t=2.5, P<0.05). The difference between the ANP levels when the pulmonary artery pressure increased medially and seriously was significant (t＝4.0 and 6.5, P＜0.05). The other two methods got the same result (P＜0.05). Results of three examining methods were positively related. Conclusion:The ANP levels can determine the degree of PAH, and it was simple. But it was not as sensitive as that of pulmonary perfusion tomographic imaging.
