Objective To explore the curative effect of standard craniotomy with large bone flap of the treatment for frontal-temporal severe craniocerebral injury patients.Methods Standard craniotomy with large bone flap was performed on 63 patients with frontal-temporal severe craniocerebral injury.All postoperative patients were followed up.The curative effect was assessed according to GOS.Results All patients were followed up for 1 year.According to the GOS,28 cases recovered well,12 cases became moderately disabled,4 cases were severely disabled,3 cases was in vegetative state and 16 cases died.The mortality rate was 25.4%.Conclusions Standard craniotomy with large bone flap is the best method of the treatment for frontal-temporal severe craniocerebral injury.Timely and thoroughly standard craniotomy with large bone flap for frontal-temporal severe craniocerebral injury patients can significantly improve the the curative effect of the patients and reduce the rate of mortality.

OBJECTIVETo investigate the effect of antisense TGF-beta 1 in inhibiting scar formation during wound healing.
METHODSSD rats were divided into three groups after skin burn: group one was treated with antisense TGF-beta 1 oligonucleotide; group two was treated with antisense TGF-beta 1 recombinant plasmid and the control group. In different time, RT-PCR and immunohistochemistry were used to verify the expression of TGB beta 1 mRNA and protein. Type I Collagen mRNA expression was determined by hybridization in situ. Inflammatory reaction and collagen distribution were observed pathologically.
RESULTSIn the groups received antisense ODN and recombinant plasmid, the expression of TGF-beta 1 mRNA and protein reduced during 14 days after burn. In the control group, type I collagen mRNA began to express at the second week and reached a peak at the fourth week, while the antisense groups kept low expression. The antisense group also showed mild inflammatory reaction and less synthesis of collagen.
CONCLUSIONAntisense TGF-beta 1 could prevent the scar formation during wound healing.

BACKGROUND:More recently, the focus has been on searching for a compound Chinese medicine for reinforcing kidney, which cannot only inhibit bone absorption, but also promote osteogenesis to protect against osteoporosis. OBJECTIVE:To explore effects of drug serum of Jianbuhuqian pil s on proliferation and function of osteoblast-like cel s in vitro. METHODS:Twenty-four adult female Sprague-Dawley rats were randomly divided into low-dose, medium-dose, high-dose and normal saline groups, and given intragastric administration of 1.5, 3.0, and 6 g/kg Jianbuhuqian pills and equal volume of normal saline, respectively twice daily for 1 week. At 1 hour after final gavage, rats were decapitated to prepare drug sera used for culturing osteoblast-like cells. At 24, 48 and 72 hours of culture, the cellular morphology was observed, as well as the cell proliferation and alkaline phosphatase activity was detected by MTT assay and alkaline phosphatase staining, respectively. RESULTS AND CONCLUSION:Compared with the normal saline group, the cel density began to increase significantly in three Jianbuhuqian groups at 24 hours after culture, mitotic figures were easy to be observed, cel s were in overlapping growth, much secretions and matrix accumulation appeared, especial y in the high-dose group. The obsorbance values in Jianbuhuqian groups were significantly higher than that in the normal saline group. After 24 hours of culture, the obsorbance values in the medium-dose and high-dose groups were significantly increased compared with the low-dose group, and the values showed significant differences among three Jianbuhuqian groups after 48 and 72-hour culture. In addition, the alkaline phosphatase activity presented overt increase in the Jianbuhuqian groups compared with the normal saline group, and significant differences could be found among Jianbuhuqian groups. To conclude, the drug serum of Jianbuhuqian pil s can promote the activity of osteoblast-like cel s in a time-and concentration-dependent manner.
