OBJECTIVETo observe the effects of antisense RNA of connective tissue growth factor (CTGF) on rat liver fibrosis.

METHODSGene recombinant techniques were used to construct a rat antisense RNA of CTGF recombinant plasmid which could be expressed in eukaryotic cells. The recombinant plasmids were encapsulated with lipofectamine and then transducted into a carbon tetrachloride (CCl4) induced rat liver fibrosis model. Expression of CTGF was assessed by RT-PCR, Western blot and immunohistochemistry. Immunohistochemistry was used to identify type I and III collagens. HE stained liver slides were used for pathological study.

RESULTSThe mRNA and protein expression of CTGF in the fibrotic liver transfected with antisense-CTGF were significantly decreased compared with those of the controls (P<0.01). The depositions of type I and type III collagens were also decreased (P<0.05). Antisense-CTGF also minimized the pathological fibrosis in the rat livers (P<0.01).

CONCLUSIONThe results demonstrate that the antisense RNA of CTGF recombinant plasmid has certain effects in preventing liver fibrosis and makes it a possible candidate for use in future gene therapy.

In order to reveal the induced resistance mechanism of tobacco treated with copper solution to potato virus Y-vein necrosis strain (PVY(N)), disease indexes, contents of virus and some physiological and biochemical indexes in tobacco were studied. The results showed that when treated at the copper concentration of 0.8 mg x L(-1), the symptom displayed and vein necrosis on tobacco were postponed, the disease index and content of virus sharply decreased , and the content of chlorophyll a, chlorophyll b and phenylalanine ammonia lyase (PAL) activity remarkably increased. Furthermore, vein necrosis closely linked to contents of total phenol and flavonoid. In this study, the contents of total phenol and flavonoid were promoted when treated with a solution at the copper concentration of 0.8 mg x L(-1). But the contents of total phenol and flavonoid reached to the first peak at the 3rd day after inoculation, and then decreased to the lowest levels which even were lower than those of the control after inoculating PVY(N). Then the contents of total phenol and flavonoid increased slowly from the 6td but still lower than those of the control. The result implied that spraying copper solution might play an important role in induced resistance of tobacco to vein necrosis disease and strengthen the antiviral capability to PVY(N).

OBJECTIVETo explore the relationship between children's motor coordination and their physical growth to provide clues for clarifying the causal relationship between them and to effectively enhance the children's physical growth.

METHODTen kindergartens were selected randomly from district of Hongkou, Putuo and Pudong in Shanghai, and 1099 children were included in the analysis. The children's motor coordination was assessed using Developmental Coordination Disorder Questionnaire (DCDQ). The relationship between the children's motor coordination and their physical growth were analyzed by Structural Equation Model (SEM). The above relationship by different gender, age and BMI (overweight or not) were analyzed with multi-group SEM.

RESULTSOf 1099 subjects, 561 were boys (51%), and 538 were girls (49%). Of the total subjects, 354 (32.2%) were children aged 3-years old, 441 (40.1%) were children aged 4-years, 276 (25.2%) were children aged 5-years, and 28 were children (2.5%) aged 6-years old. The result of SEM showed that the children's gross motor, fine motor and general motor ability was correlated positively with children's physical growth (P < 0.001), their standardized estimation of structural coefficient were 0.40, 0.36, 0.37 respectively. The result of multi-group SEM showed that there was no significant difference in the SEM between different gender and ages. The fine motor ability was positively correlated with child physical growth (P < 0.001). There was no inter-group difference in the structural model (each P > 0.05). However, there was difference in the structural model between overweight and normal group, of them, only the structural coefficient of gross motor and physical growth were different between the two groups (t = 1.697, P < 0.05).

CONCLUSIONThere is a relationship between children's motor coordination and physical growth. The degree of association between the gross moter and physical growth in overweight children were different from the normal children. Further study on the factors influencing the children's physical growth is needed.
