YMDD mutation: HBV YMDD mutation were developed in 12 lamivudine recipients, whereas the treated group had no incidence of HBV YMDD variation, there were significant difference between two groups (p=0.000). YMDD mutation resulted in increase of the mean HBVDNA levels (p=0.000), but no contribution to serum ALT diversification (p＞0.05). 2. Precore nt1896 mutation: Precore nt1896 mutation incidence had no difference between lamivudine recipients and objects who received combination therapy of Kidney-invigorating Granule and Marine Injection, and patients of HBeAg negative and HBeAg positive had a close incidence of precore mutation as well as. Precore nt1896 mutation had no influence on serum ALT level. The occurrence of precore nt1896 mutation contributed to serum HBVDNA load increased and worse response of HBVDNA extenuation. 3. HBV genotype: The baseline of serum HBVDNA gradually increase in turn of genotype B, genotype C and genotype B/C. Genotype B seemed to obtain higher rate of serum HBVDNA loss and HBeAg/anti-HBe seroconversion after combination therapy of Kidney-invigorating Granule and Marine Injection, differencing with lamivudine therapy.

The following conclusions have been made in this paper.(1) Based on CO_2 flux data of eddy covariance, variation characteristics of gross primary productivity in four flux observation stations were studied, which are an alpine meadow, an alpine shrub meadow, a swamp alpine meadow and a steppe alpine meadow at Dongxiong. The results show that photosynthetic capacity of the alpine meadow is the highest, and the annual total GPP is 652.2g C/m~2. Daily-differencing approach is used to analyze the random error of CO_2 fluxes measurements. The results show that the distribution of random error follows more closely follows a double-exponential, rather than a normal distribution, capturing the high peak and thick tail, and the random error varies with environment variables, which violates the assumptions for the ordinary least squares fitting with normality and homoscedasticity, consequently, we introduce maximum likelihood method for parameter optimization.
