Objective To observe the changes of serum calcium, phosphorus, calcium-phosphorus product and para-thyroid hormone(PTH)levels after treatment with different concentrations of calcium dialysate in combination with calcitri-ol. Methods Thirty-six patients on maintenance hemodialysis were randomly divided into Dca1.25 group and Dca1.5 group, 18 cases in each group. Patients took different doses of calcitriol on the different values of PTH basis. Changes of se-rum calcium, phosphorus, calcium-phosphorus product,PTH and bone alkaline phosphatase (BAP) levels were recorded re-spectively on four time points from prior treatment and 1, 3 and 6 months of therapy. The levels of systolic blood pressure (SBP) and diastolic blood pressure (DBP) were also observed. Results There was an interaction between treatment effects and time effects in serum calcium, phosphorus, calcium-phosphorus product levels in two groups (P<0.05). With the dura-tion of treatment, there was a trended to decrease and increase respectively in DCa 1.25 group and DCa 1.5 group, and trend-ed to stabilize for therapy 3 to 6 months. There was no interaction between serum PTH and BAP levels and time effects in two groups. There was no statistical difference in simple treatment effects and time effects. The serum PTH level showed a trend of increase gradually in DCa1.5 group with the duration of treatment. In DCa 1.25 group, the serum PTH level trended to stabilize after 3-month therapy and showed a trend of decrease gradually. There was an interaction between treatment effects and time effects in SBP in two groups, but no interaction in DBP. There was a significant difference in SBP before and after treatment in two groups. The level of SBP reduced tardily with time of treatment and reduced significantly after 3 and 6-month therapy. Conclusion The application of DCa1.25 dialysate in combination with calcitriol decreased serum calci-um effectively and kept the lower limit of normal value, which increased tolerability of active vitamin D and calcium carbon-ate therapy, and decreased SBP in maintenance hemodialysis patients.

Through potted inoculation test at room temperature and indoor analysis, the photosynthetic parameters and physiological and biochemical indexes of Paris polyphylla var. yunnanensis were observed after 28 arbuscular mycorrhizal (AM) fungi were injected into the P. polyphylla var. yunnanensis growing in a sterile soil environment. The results showed that AM fungi established a good symbiosis with P. polyphylla var. yunnanensis. The AM fungi influenced the photosynthetic parameters and physiological and biochemical indexes of P. polyphylla var. yunnanensis. And the influences were varied depending on different AM fungi. The application of AM fungi improved photosynthesis intensity of P. polyphylla var. yunnanensis mesophyll cells, the contents of soluble protein and soluble sugar, protective enzyme activity of P. polyphylla var. yunnanensis leaf, which was beneficial to resist the adverse environment and promote the growth of P. polyphylla var. yunnanensis. Otherwise, there was a certain mutual selectivity between P. polyphylla var. yunnanensis and AM fungi. From the comprehensive effect of inoculation, Racocetra coralloidea, Scutellospora calospora, Claroideoglomus claroideum, S. pellucida and Rhizophagus clarus were the most suitable AM fungi to P. polyphylla var. yunnanensis when P. polyphylla var. yunnanensis was planted in the field.

Objective To understand the evolutionary characterization of hemagglutinin (HA)gene of pandemic H1N1 influenza virus in Guangdong during 2009-2011. MethodsWe selected 83 pandemic H1N1 strains isolated in Guangdong during 2009-2011. The HA1 genes were sequenced and analyzed comparatively by Bioedit 7.0 and MEGA 4.0. ResultsThe evolutionary rate of Hal gene of pandemic H1N1 and seasonal H1N1 viruses was 5.2×10-3 substitutions/site/year, higher than that of seasonal H1N1 viruses. Most amino acid changes in HA1 molecules accumulated on the surface of the molecule and were partly located in antigenic sites. Two fatal infections were detected with a mutation at HA residue 222, in one virus with a change D222G, and in one virus D222N. ConclusionThe phylogenetic analysis demonstrates that the influenza epidemic in Guangdong at the beginning of 2011 are due to occurrence of genetic changes of pandemic H1N1 virus. The amino acid change at residue 222 of the HA1 are likely to be associated with severe or even fatal illness.
