Schisandra chinensis (Turcz.) Baill. is an important medicinal plant in northeast China. Cutting propagation is an effective method for the rapid propagation of many tree species. This research aimed to determine a suitable growing medium and appropriate root hormone type, concentration and treatment time through the utilization of different substrates and hormones to treat one-year-old branches of S. chinensis. The optimal treatment achieved a rooting rate of 60% with 225 ppm ABT and 75 ppm NAA for 2.5 h. The substrate of vermiculite/perlite = 1:1 (urea+potassium) was beneficial to the adventitious root formation, which reached 79%. The adventitious root primordium of S. chinensis originated from the junction of the xylem and cambium. ABT and NAA treatments altered the peak timing of POD, PPO and IAAO in S. chinensis cuttings. During the adventitious root formation of S. chinensis cuttings, the high endogenous IAA concentration promoted the occurrence of adventitious roots in the early stage and the lower endogenous IAA and GA3 concentrations promoted the elongation and growth of adventitious roots in the later period. Low ABA and ZR concentrations enabled adventitious root formation and elongation. An efficient cutting propagation system would enable the mass propagation of S. chinensis seedlings.

Studied the vibration performance of honeycomb paperboard with double cross-core, obtained vibration transmissibility curve of honeycomb paperboard with double cross-core, by the curve indicated, the vibration transmission properties of the honeycomb paperboard with double cross-core in the sinusoidal excitation ,and the packaging materials as contents when the size of the protection capacity. The results show that the shock resistance capacity of honeycomb paperboard with double cross-core is supers the single layer with the same thickness of.

Serological samples of healthy people were collected to obtain the levels of measles antibodies in different groups of people in Heilongjiang Province, China. Using quantitative enzyme-linked immunosorbent assays to measure the antibody levels, we found the lowest antibody positive rate and the lowest geometric mean concentration values in healthy people aged 15-39. This group is the population at high risk for adult measles in Heilongjiang Province, and is the focus of measles elimination work. The new challenges for the eventual elimination of measles will be to address immunization strategies in this segment of the population in order to control the incidence.
