Objective Percutaneous puncture of gasserian ganglion was guided by CT scan to improve the accuracy and reduce complications and to compare the efficacy of chemical mutilation with ethyl alcohol and adriamycin.Methods Ninety-two patients with primary trigeminal neuralgia (39 males, 53 females) aged 37-84 yrs were divided into two groups : A ethyl alcohol group ( n = 47) and B adriamycin group ( n = 45) . Secondary trigeminal neuralgia was excluded by preoperative CT scan. Percutaneous puncture of oval foramen was guided by CT and correct location of needle tip was confirmed by injection of contrast medium. 100% ethyl alcohol 0.5ml (group A) or 2% adriamycin 0.5ml was injected.Results The patients were followed up for 12 months after treatment. Neuralgia disappeared in 31 out of 47 patients in group A (alcohol group) and in 36 out of 45 patients in group B (adriomycin group) . Treatment failed in 13 patients in group A and 6 patients in group B, and was partly effective in the other patients. There were no severe side effects or complications. Conclusion Percutaneous puncture of gasserian ganglion guided by CT is effective and reduces complications. Adriamycin is more effective than ethyl alcohol for chemical mutilation.

Objective To investigate the effect of fluoride on expression of Runx2 mRNA and protein in bone tissue of rats. Methods Fourteen SD rats were randomly divided into two groups: control group(tap water with fluoride < 0.06 mg/L), and fluorosis group(fluoride 50 mg/L in water). After 4 moths, expressions of both mRNA and protein of Runx2 in rat bone tissue were determined by RT-PCR and Western blotting. Results The results showed that the expression of Runx2 mRNA and protein in fluoride-treated bone tissue were 2.287 ± 0.261 and 0.929 ± 0.229, respectively, both of which were significantly higher than those of control group(0.995 ± 0.123,0.317 ± 0.068, t = 11.85,6.78, P < 0.05). Conclusions Fluoride can increase the expression of Runx2 mRNA and protein in bone tissue of rats, and Runx2 may be involved in the pathogenesis of bone injury caused by fluoride.

Objective To analyze diagnosis and management of traumatic atlantal fractures complicated with disruption of the transverse atlantal ligament. Methods Twenty-six patients with traumatic atlantal fractures complicated with disruption of the transverse atlantal ligament, 20 acute ones and six old ones, were managed in our department from March 1995 to March 2005. All the patients had the symptom of neck pain and a certain extent of neurological deficits. The radiographic examination showed that there were fractures in the anterior arch or/and lateral mass of the atlas and that the atlanto-dental interval (ADI) in these patients was 4 to 7 mm. Twenty-one cases were operated on with occipitocervical or atlantoaxial fusion immediately after injury. Five cases received conservative treatment. Results All were followed up for 15 (from 6 to 24) months on average. The 21 cases treated operatively reported relieved symptoms. Four of the five conservative treatments succeeded, but one of them underwent a successful atlantoaxial fusion because the original conservative treatment had failed. Conclusions The severity of clinical symptoms mostly depends on the degrees of atlantal displacement and cord compression. Diagnosis should be made on the basis of the ADI change as well as clinical presentations. For patients who have potential risk of atlantoaxial instability, occipitocervical or atlantoaxial,usion should be performed early.
