ObjectiveTo understand dangerous factors causing child cerebral palsy and try to diagnose and treat cerebral palsy early, and decrease the ratio of cripple.MethodsTo analyze if the occurrence, style or complication of cerebral palsy having a relation to dangerous factors such as sexes, birth weight, premature delivery, twins, neonatal asphyxia, infection of newborn, nuclear icterus, mother's age, virus infection in the duration of pregnancy, threatened abortion and family history of cerebral palsy.ResultsThe ration of male and female is 1.47∶1 in 146 cases of child cerebral palsy. Factors causing cerebral palsy are low birth weight (79.45%), premature delivery (64.38%), neonatal asphyxia (41.78%), threatened abortion (32.89%), twins (31.53%), infection of newborn (12.33%), nuclear icterus (6.16%), parturient with advanced age (3.42%), having infection history in the duration of pregnancy (2.74%), and family history of cerebral palsy (0.68%). Both styles and complications of cerebral palsy have a relation to dangerous factors.ConclusionsThe low birth weight, premature delivery, neonatal asphyxia, twins and threatened abortion all are higher dangerous factors causing child cerebral palsy. In order to abstain the occurrence of these dangerous factors, it is important to educate people and doctors recognizing all dangerous factors. It is also helpful to lower the ratio of cripple that regularly examining child with dangerous factors, discovering symptoms and complications of cerebral palsy in time, and diagnosing and treating cerebral palsy as soon as possible.

Objective To explore the effect of the simvastatin administration on the expression of connective tissue growth factor （CTGF） in fihrotic lungs of rats. Methods The cats were treated with single intratracheal instillation of bleomycin （BLM） or instillation of the same volume of normal saline （NS） as a control. The administration of simvastatin（20 mg/kg）began once a day immediately or 7 days later after intratracheal BLM instillation respectively with the same volume of NS was given as a vehicle control. The rats were killed on day 7,14 and 28 respectively. Pathological alteration of lung tissue was observed hy HE staining and Masson staining. Hydroxyproline（HYP）content in lung tissue was used to determine the severity of pulmonary fibrosis. The expression of CTGF in lung tissue was exanfined by immunohistochem- istry staining and photodeusitometry. Results Histopathological changes of pulmonary fibrosis emerged gradually after the instillation of BLM. The expression level of CTGF was increased in lungs of rats after intratracheal instillation of BLM, compared with the control. The administration of simvastatin immediately or 7 days after intratracheal instillation of BLM, attenuated the histopathological changes of bleomycin- induced puhnonary fibrosis and prevented the increased expression of CTGF in lung tissue on day 28. Conclusion The adntinistration of simvastatin, immediately or 7 days after intratracheal BLM instillation, prevented the up-regulation of CTGF in fibrotic lungs of rats, which ntight be one of the mechanisms of the anti-fihrosis of simvastatin in lungs.

AIM:To compare 2 environments , the subrenal capsule and oral submucosa , for producing well-formed teeth from mouse tooth germs and for exploring the ideal environment for tooth regeneration .METHODS: Two groups were set up .Group A was transplanted with the mouse embronic day ( ED) 14.5 first mandibular molar tooth germs into the subrenal capsule , while group B was transplanted with the ED 14.5 first mandibular molar tooth germs into the oral submucosa.After 3 weeks and 4 weeks, the host mice were sacrificed, and the transplanted explants were evaluated with morphologic observation , histological structures , hardness and elastictic modulus tests , and chemical compositions .RE-SULTS:(1) The explants isolated from both environments showed the tooth-like structures, but as to the group B, the crown was smaller, and the shape of the cusps was not significant .(2) HE staining showed that the dentin and enamel in group A were thicker than those in group B in which the ameloblasts and odontoblasts were differentiated not very well .(3) In the test of enamel hardness , only the hardness of 4 weeks in group B was lower than normal mouse tooth .In the test of enamel modulus , the elastic modulus of enamel in 3 weeks of group A was slightly lower than normal mouse tooth , but the difference was not significant .The elastic modulus of enamel in 4 weeks of group A and group B was significantly lower than normal mouse tooth and 3 weeks of group B .The hardness and elastic modulus of dentin in 3 groups was not significant . (4) Raman spectroscopy showed 2 groups grew in harmony in general , they all had the largest peak in the point of 961 cm-1 , but the 3 weeks of group B had an obvious peak in the point of 2 947 cm-1 .CONCLUSION:For the development of ED14.5 tooth germs, we obtain almost the whole tooth in subrenal capsule transplantation after 3 or 4 weeks.The buccal submucosa environment still has a certain influence on the tooth germ development , although there are some differences about the tooth development between this environment and subrenal capsule environment .

AIM:To investigate the effect of cigarette smoking condensate on histone deacetylase 2 (HDAC2) and inflammatory mediators in mouse myoblast C 2C12 cells.METHODS:C2C12 cells were treated with cigarette smoke extract (CSE).HDAC2 siRNA was transfected into the cells using Lipofectamine TM 2000.The levels of interleukin-8 (IL-8) and tumor necrosis factor-α( TNF-α) in the culture supernatants were measured by ELISA , and the expression of HDAC2 at mRNA and protein levels was determined by real-time PCR and Western blotting .RESULTS:The expression of HDAC2 at mRNA and protein levels in CSE group was lower than that in control group (P<0.05).The supernatant levels of IL-8 and TNF-αin CSE group were significantly higher than those in control group ( P<0.05 ) .When the cells were transfected with HDAC2 siRNA followed by CSE stimulation , the expression of HDAC2 at mRNA and protein levels was de-creased , and the supernatant levels of IL-8 and TNF-αwere significantly increased as compared with CSE group and control group (P<0.05).CONCLUSION: Under the oxidative stress condition , C2C12 cells generate high levels of IL-8 and TNF-αby down-regulating the expression of HDAC2.

The distribution fate and solubilization behavior of indomethacin through the intestinal tract were investigated with in vitro lipolysis model, by comparing the Capmul MCM and Labrafil M 1944 CS type I lipid formulations. The results showed that the more favorable solubilization was in the aqueous digestion phase from each lipid formulations for indomethacin. The lipolysis rate and extent were decided with chemical constitution of the lipid excipients, which meant that less indomethacin was transferred from the long chain polar oil lipid solution into the aqueous digestion phase. Increasing the concentration of indomethacin in the lipid formualitons from a solution to a suspension led to a linear increase in the concentration of indomethacin attained in the aqueous digestion phase from lipid formulations. This study also implied that adverse effects of the lipolysis rate and extent on drug absorption were could be taken into consideration when screening lipid formulations. Lipid suspensions likely had better enhancement of drug absorption. Last, this study demonstrated that a potential basis for optimizing and assessing type I lipid formulations and also researching in vivo-in vitro correlations of lipid formulations were provided by an in vitro lipolysis model.

A new dynamic in vitro intestinal absorption model for screening and evaluating lipid formulations was established by means of the characteristics of the intestinal digestion and absorption of the lipid formulations. This model was composed of two systems, including intestinal digestion and the intestinal tissue culture, which drew the evaluation method of intestinal absorption into the in vitro lipolysis model. The influence of several important model parameters such as Ca2+, D-glucose, K+ on the two systems of this model has been investigated. The results showed that increasing of Ca2+ concentration could be significantly conductive to intestinal digestion. The increasing of D-glucose concentration could stepped significantly down the decay of the intestinal activity. K+ was able to maintain intestinal activity, but the influence of different concentration levels on the decay of the intestinal activity was of no significant difference. Thus the model parameters were set up as follows: Ca2+ for 10 mmol x L(-1), D-glucose for 15 mmol x L(-1) and K+ for 5.5 mmol x L(-1). Type I lipid formulation was evaluated with this model, and there was a significant correlation between the absorption curve in vitro and absorption curve in vivo of rats (r = 0.995 6, P < 0.01). These results demonstrated that this model can be an attractive and great potential method for the screening, evaluating and predicting of the lipid formulations.
