Journal of Practical Radiology 2001;0(05):-
Objective To evaluate the diagnostic value of the C 2 “hypertrophic sign” in the axis fracture.Methods 37 cases with C 2 fracture confirmed by radiography,CT and operation partly retrospectively analysed,there were 29 men and 8 woman.After trauma all cases were examined by X-ray and 11 cases by CT scan.27 cases underwent operation.Results The incidence rate of the C 2 “hypertrophic sign” was 53.13%.This sign characterized by the distance increased between the anterior and posterior of the axis on the lateral conventional radiography compared with that of C 3 vertebrae.The maximal increasing distance was 11 mm and minimal one was 2.3 mm with average 4.3 mm.Fracture line and swollen soft tissue in front of the vertebra were showed in some cases.Conclusion The C 2 “hypertrophic sign” is main radiographic sign of C2 fracture.

500?mol/L) of propofol was needed; In biological system near the range of anaesthetic concentration, propofol effectively scavenged oxygen free radical produced by respiratory burst of PMN. Conclusion: Propofol scavenging hydroxyl radical generated in biological and nonbiological system,may be one of the main mechanisms of its antioxidation,the intralipid component of Diprivan may affect its antioxidation.

Objective To evaluate the value of standard large trauma craniotomy in frontotemporal and parietal contrecoup craniocerebral injury.Methods Forty-six patients with frontotemporal and parietal contrecoup craniocerebral injury were treated by standard large trauma craniotomy. Based on GOS, the clinical curative effect and complications of these patients during 3 to 6 months after operation were evaluated.Results 22 cases (47.83%) recovered well, 6 cases (13.04%) suffered from moderate disability, 4 cases (8.7%) remained severe disability, and 14 cases (30.43%) died. The common complications after operation were delayed intracranial hematoma, cerebral penetrating malformation, hydrocephalus, defect of skull syndrome and so on.Conclusion Standard large trauma craniotomy is a good therapeutic method for frontotemporal and parietal contrecoup craniocerebral injury.

Objective To compare the effect of spinal anesthesia by using 0.75% ropivacaine or 0.5% bupivacaine in a simulated state of rocking naval vessels, in order to choose an optimal anesthetic agent in a rocking naval vessels at sea. Methods Eighty patients undergoing elective surgery of abdomen or lower limb were randomly divided into 4 groups (n=20). Namely, horizontal level with 0.75% ropivacaine control group (R1), horizontal level with 0.5% bupivacaine control group (B1), simulated rocking with 0.75% ropivacaine group (R2), simulated rocking with 0.5% bupivacaine group (B2). The effect of anesthesia, the changes in hemodynamics and the incidence of relevant side-effects were determined and compared among the four groups. Results The anesthetic level (analgesic level) of group B2 was 2.7 segments higher than that in group B1, and the durations for fixed level was longer than group B1 (P

The use of genetic approaches to probe relative genes that control sensitivity to volatile anesthetics in intact model has recently emerged as the powerful tools and strategies in dissecting mechanisms of anesthesia. Multiple model organisms such as yeast, nematodes, fruitflies and mammals are currently being exploited, and a number of sensitive genes have been screened, with some of them being cloned, located, and function identified. The emerging technologies are likely to provide further great advances for elucidating the specific anesthetic molecular sites.

G1.(3)Among 5 groups,the highest incidences of nausea,vomiting and pruritis were observed in group G1 for about 24% 32%,but with no statistical difference compared with other groups.Conclusion: With equal doses of bupivacaine and fentanyl mixed,the concentration/volume ratios may affect the analgesic effects of postoperative epidural analgesia in patients with hepatectomy.

Objective:To investigate the protective effects of nuclear factor ?B inhibition on liver graft reperfusion injury during transplantation.Methods:Orthotopic liver transplantation using modified cuff technique was established in rats,animals were divided according to the grafts cold storaged in 4℃ Ringer's lactated solution with(PDTC group)or without 0.1 mol/L PDTC(control group)for 6 h.During the early stage of reperfusion,DNA binding activities of NF ?B in liver grafts were analyzed by EMSA(electrophoretic mobility shift assay),mRNA level of TNF ? and ICAM 1 by RT PCR,and activities of ALT and LDH were also detected.Results:NF ?B in liver grafts was activated at early stage of reperfusion during transplantation; PDTC treated liver displayed lower activation of NF ?B 1 h after reperfusion,whereas no difference was shown between 2 groups 6 h after reperfusion.Up regulation of TNF ? and ICAM 1 transcription,high level of ALT and LDH activities were observed in both groups during reperfusion,whereas the transcriptional up regulation and the activities of ALT and LDH in PDTC group were reduced compared with those of control group( P

Objective:To investigate the influence of propofol on the binding function of GABA A receptor. Methods: By using radioligand receptor binding assay, effects of propofol on the specific binding of 3H GABA and saturation curves of GABA A receptor were observed in cortical membrane preparations from mouse cerebral cortex. Results: Specific binding experiments showed that propofol at the concentrations of 10 300 ?mol/L markedly enhanced the specific binding of 3H GABA( P 0.05). Conclusion: Clinical concentrations of propofol can enhance the binding function of GABA A receptor through increasing the affinity of the low affinity binding site of GABA.
