Floral morphogenesis and the development of Cercidiphyllumjaponicum Sieb. et Zucc. were observed by scanning electron microscopy （SEM）. The results showed that the pistillate inflorescences were congested spikes with the flowers arranged opposite. Great differences between the so-called ＂bract＂ and the vegetative leaf were observed both in morphogenesis and morphology. In morphogenesis, the ＂bract＂ primordium is crescent-shaped, truncated at the apex and not conduplicate, has no stipule primordium at the base but does have some inconspicuous teeth in the margin that are not glandular. The leaf primordium is triangular, cycloidal at the apex, conduplicate, has two stipule primordia at the base, has one gland-tooth at the apex occurring at first and some gland-teeth in the margin that occur later. In morphology, the ＂bract＂ is also different to the vegetative leaf in some characteristics that were also illustrated in the present paper. Based on the hypothesis that the bract is more similar to the vegetative leaf than the tepal, we considered that the so-called ＂bract＂ of *** might be the tepal of the pistillate flower in morphological nature. Therefore, each pistillate flower contains a tepal and a carpel. We did not find any trace of other floral organs in the morphogenesis of the pistillate flower. Therefore we considered that the unicarpellate status of extant Cercidiphyllum might be to highly reduce and advance characteristics that make the extant Cercidiphyllum isolated from both fossil Cercidiphyllum-like plants and its extant affinities.

Crosslinked film of hyperbranched poly（amine-ester）（HPAE） was prepared by crosslinking its terminal hydroxyl groups with glutaraldehyde （GA）. Atom force microscope （AFM） and scanning electron microscope （SEM） reveals that they have smooth surfaces, dense and homogenous matrices. It was found that the water static contact angle is smaller than 41.7°, the tensile strength is higher than 8.9 MPa, the elongation at break is higher than 5.1%, the swelling degree is higher than 42% in water, and the Bovine hemoglobin （Hb） adsorption is relatively low. These results indicate that the crosslinked HPAE films might have some potential applications in many areas.

hap, a novel human apoptosis-inducing gene which can interact with another newly discovered apoptosis-inducing geneASY, was identified, by cloning its cDNAs from human lung cell line (WI-38) cDNA library. Two major mRNA species (1.8 and 2.7 kb in length, respectively) were previously identified by Northern blot analysis of poly(A)+ RNA from human multiple tissues using partialhap cDNA as a probe. In the present work, the molecular mechanism accounting for the generation of the twohap transcripts were investigated. The rapid amplification of cDNA 3′-ends (3′-RACE) technique and the sequential Southern blot analysis, in conjunction with the sequencing analysis demonstrated that the twohap transcripts derive from the alternative polyadenylation site selection: a AATAAA signal at position 1 528–1 533 nt for the 1.8 kbhap mRNA: and a AATAAA signal at position 2 375–2 380 nt for the 2.7 kbhap mRNA. Furthermore, a number of regulatory elements withinhap 3′-untranslated region (3′-UTR) were also examined.

This paper is concerned with evolving objects method for software design that can adapt to the changing environments and requirements automatically. We present system architecture with objects library, where there are objects based on domain ontologies. We define some genetic operators for objects, and discuss how to apply these genetic operators on objects to get new objects, which can satisfy new requirements.

Objective: To explore the clinical value of X-ray digital tomosynthesis(DTS)in the diagnosis of knee joint fractures. Methods: A total of 28 cases of thoracic trauma, X-ray film cannot be clearly diagnosed or can confirm the diagnosis but the need for further identification of forensic diagnosis of cases of DTS scan and three-dimensional reconstruction in order to control the study. Results: 1. The reconstructed images after DTS scanning showed that the knee joint fractures were clearly diagnosed, and the detection rate of 28 knee joint fractures was 92.86%. 2. DTS scanning could clearly detect the fresh knee joint fracture's fracture line, corresponding line and broken bones. For the old fracture, DTS scanning could clearly show the condition of the fracture end's healing. Conclusions: The technique is of great value in the diagnosis of knee joint fracture, especially in the examination of complex structure, thick body and review of internal fixation after fracture.

Objective Microvesicles (MV) released from blood cells play an important role in the progress of diseases. The purpose of this study is to detect circulating MV level of patients suffering from severe fever with thrombocytopenia syndrome (SFTS) . Methods The plasma samples of SFTS patients and healthy controls were collected. And MV from samples were isolated and MV levels were detected quantitatively. Results The results showed that the level of the circulating MV in SFTS patients was obviously higher than that of the healthy control, with statistically signiifcant difference. Further analysis revealed that MV level was relevant to the severity of SFTS patients, namely the higher the concentration of MV, the more severity of the disease. Linear correlation analysis showed that the circulating MV level in SFTS was correlated positively with leukocyte count (r=0.243, P0.05). Conclusions We demonstrated that there existed high level of circulating MV in SFTS patients, and the level of circulating MV had a close relationship with the severity of the disease and leukocyte count. Therefore, monitoring the level of circulating MV may provide a new insight for predicting the prognosis of SFTS patients.
