Objective To investigate the role of community-based intervention among diabetic patients for the control of blood glucose,blood fat,blood pressure and body weight. Methods Patients in a specific community with type 2 diabetes mellitus were selected in the study,with 133 in the exercise group,200 in the integration group and 140 in the control group.Intervention and followup were conducted for 8 months,and clinical parameters including blood glucose were detected. Results Both exercise and integrated therapeutics could decrease the levels of fasting blood glucose(FBG) and postprandial 2-h blood glucose,with a more significant descending degree in the integration group than the exercise group(P

To investigate me material basis of Mahuang Fuzi Xixin decoction (MFXD) for anti-inflammation and immune-suppression based on the combined method of serum chemical and serum pharmacological. The LC-MS/MS fingerprints of MFXD, drug-containing serum and blank serum were compared to define the components in plasma. Histamine, β-hexosaminidase released from RBL-2H3 cell infulenced by drug-containing serum at different time points were measured by ELISA. The effect of drug-containing serum on lipopolysaccharide-induced splenocyte proliferation at different time points were determined by MTT. A correlation analysis was made on components of MFXD and pharmacological indexes based the stepwise regression method. After the intragastrical administration with MFXD, 32 components were discovered in rat serum, including 27 prototype components (10 from Mahuang, 13 from Fuzi and four from Xixin) and five unknown components. Compared with blank serum, drug-containing serum could reduce the release of histamine from RBL-2H3 induced by antigen at different time points (P < 0.05); except the 4-hour drug-containing serum, all of the remaining drug-containing serums could inhibit the RBL-2H3 mastocyte degranulation induced by antigen at different time points (P < 0.05). Drug-containing serum could significantly lipopolysaccharide-induced mouse splenocyte proliferation at 15 and 30 min (P < 0.05). A regression analysis was made on the chemical data of components absorbed into blood and pharmacological indexes, i. e. release rate of histamine, release rate of β-hexosaminidase and inhibition rate of splenocyte. This suggested the close correlations among methyl pseudo-ephedrine, pseudoephedrine and histamine released from RBL-2H3 induced by antigen; pseudoephedrine, hypaconine, methyl pseudoephedrine and β-hexosaminidase released from RBL-2H3 induced by antigen; as well as benzoyl hypaconine, benzoylaconine, 14-benzoyl-10-OH-mesaconine, mesaconine and lipopolysaccharide-induced mouse splenocyte proliferation. Methylpseudoephedrine, pseudoephedrine, benzoyl hypaconine, benzoylaconine and mesaconine may be part of material basis of MFXD on anti-inflammation and immune suppression.

ObjectiveTo study the effects on growth characteristics of cells mutated by outer space. Methods5 tumor cell lines and 1 bio-pharmaceutical cell line were carried in the recoverable satellite No.18 and returned after 18 days flying in outer space.The cell living systems were utilized in passive carrying. Some survival cells were monocoloned, and the experimental methods such as cell morphological observation,MTT assay and FACS were used for analysis of cell growth characteristics. ResultsThe survival cell rates of tumor cell lines and bio-pharmaceutical cells were markedly different. Compared with the control group, mutated cells appeared to have multiple cell morphological changes and the cell number of G1 phase was increased markedly (P<0.05). Growth rate in mutated cells were varied without specific discipline. ConclusionEffects of outer space on growth characteristics were complicated and multiplex in mutated cells,which were not all heredity in further passage. The differences of the monoclonal cell lines provide the potential to obtain optimizing cell lines by screen.

ObjectiveTo develop the facility of mammalian cell culture in hypothermia for long-term, and to lay the base for carrying mammalian cells to outer space and establishing outer space biomedical research stage. MethodsMultiple cell lines were maintained in the spacial designed hypothermia cell culture facility and carried to space by Shenzhou 4 and No.18 recoverable satellite. Cell morphology, cell multiplication and the ability to be monocloned were observed.ResultsCells were successfully maintained in the hypothermia cell culture facility for up to 26 days without obvious changes of cell morphology. The cells could normally grow, multiple and be monocloned after inoculated in 37 ℃ for 8 h.ConclusionA hypothermia cell culture facility was successfully established,which ensure technically mammalian cells to be carried by space craft and further research on space radiation.

ObjectiveTo validate the feasibility of the outer space carrying system in culturing the CHO(dhfr-)cells in hypothermia, and to observe the effects of this carrying system on the growth characteristics of the CHO(dhfr-) cells.MethodsThe growth characteristics of the CHO(dhfr-) cells were observed and analyzed with cell morphological observation, MTT assay, FCM,3H incorporation and chromosome after the cells were cultured for 25 days in the carrying system. ResultsComparing with the control group, the CHO(dhfr-) cells appeared multiple cell morphological changes, the difference of cell cycle was not significant, the broken chromosome was not seen, the cell growth speed decreased markedly and big molecular biosynthesis increased obviously. ConclusionThe outer space carrying system has no outstanding effects on the survival and heredity of the CHO(dhfr-) cells, so that it can be used in cell carry.

Objective To screen the optimum conditions carrying murine melanoma B16 cells in spaceflights without cares.MethodsMurine melanoma cells were cultured on micocarriers and grouped depending on cells concentration, serum concentration, microcarrier number and temperature.After 33 days, B16 cells were stained by Giemsa, observed with phase-contrast microscope and counted for surviving percentage.ResultsThe optimum conditions,in which the surviving percentages were 8% and 10%, were obtained in the experiments.B16 cells were carried in the 20th recoverable satellite orbiting 18 days under the optimum conditions. After recovering, 110 strain monocloned cells were survived and the surviving percentage was 1.1%.ConclusionThe optimum conditions carrying murine melanoma B16 cells in spaceflights without cares seems to be obtained,and it did improve the surviving time and percentage of cells in spaceflights without cares.

The paper is aimed to study the dynamic accumulation regulation of curcumin (Cur), demethoxycurcumin (DMC) and bisdemethoxyeurcumin (BDMC) in three strains of Curcuma longa, and provide scientific references for formalized cultivation, timely harvesting, quality control and breeding cultivation of C. longa. The accumulation regulation of the three curcumin derivatives was basically the same in rhizome of three strains. The relative contents decreased along with plant development growing, while the accumulation per hectare increased with plant development growing. The accumulation of curcuminoids per hectare could be taken as the assessment standard for the best harvest time of C. longa. A3 was the best strain in terms of Cur and BDMC content.

The morphological index of the seedlings including the plants height, the ground diameter, the leaf amounts, the fresh weight of the whole plant and the ratio of height to diameter was measured and the principal components were analyzed so as to determine the grading index, and stepwise cluster analysis was applied for clustering analysis. Pot experiments were used to measure the indicators of plant growth and development, the yield and the quality. The results showed that the height and ground diameter were determined as the quality indicators of the seedlings grading and the standard quality grading of seedlings of Anoectochilus roxburghii was initially set up, different seeding plants influenced the plants growth and the yield. The ground diameter of the class I was larger than that of the class II and III, so as the yield. The seedling grading had no obvious effect on the internal quality of medicinal materials. The results of the study provide the basis for standard cultivation of A. roxburghii.
