METHODS: AC from neonatal mouse brain was incubated for 24 h in serum-free medium under hypoxic or normoxic conditions. The amount of transferred RNA was estimated using ethidium bromide stained 28S rRNA and 18S rRNA. The levels of tested mRNA were evaluated by Northern blot RNA hybridization. RESULTS: The GAPDH mRNA was up-regulated to 503.0% of the normoxic controls in hypoxic AC (n=10. P

Objective To introduce the method of C2,3 pedicle screw fixation for management of unstable Hangman fractures and evaluate the clinical effects.Methods From October 2001 to October 2005,26 cases with unstable Hangman fractures were treated using Axis and Vertex pedicle screw system.According to the classification system designed by Levine depending on the radiological manifestations of Hangman fractures,there were unstable fractures in 26 cases,who were subdivided into type Ⅱ in 11 cases,type ⅡA in 10 cases and type Ⅲ in 5 cases.There were 18 males and 8 females,aging from 21 to 56 years with an average of 38.5 years.According to Frankel scale,graded as spinal injury D in 6 cases and E in 20 cases.Points of entry for C2 screw insertion were located at the entrance at the posterior aspect of lateral mass.The drill bit was parallel to both of the medial and superior border of C2 pars interarticularis(usually 15?-25? cephalad to the transverse plane and 20?-25? medial to the sagittal plane).The screw hole in the posterior cortex was overdrilled.3.5-4.0 mm screws(26-30 mm,determined by depth gauge)were drived in after the cortex being tapped.The points of screw penetration for the C3 pedicles was slightly lateral to the center of the articular mass and close to the inferior margin of the inferior articular process of the cranially adjacent vertebra.The insertion angle of the pedicle screw was 35?-45? medial to the midline in the transverse plane.3.5-4.0 mm screws,determined by depth gauge were drived in after the cortex being tapped.The whole procedure was done under monitoring of "C"-arm fluoroscopy for safety and accuracy.Results All patients were followed up from 6 to 54 months,with the average of 29 months.There were no screw loosing and breakage,and no spinal cord and vertebral artery injury after surgery.3 screws were placed too close to the vertebral artery canal in C2 and 7 screws in C3,but without clinical consequences.There were 16 cases in excellent,7 good,3 fair according to Mayo(McGrory)scores.Conclusion C2,3 pedicle screw fixation is a effected method for management of unstable Hangman fractures,which proved its value as a method achieving solid bony fusion combined with low rate of complications.

Objective To evaluate the feasibility of suprasternal mini-thyroidectomy.Methods A total of 15 patients with nodular goiter underwent suprasternal mini-thyroidectomy(2.5-3.5 cm in incision at length) with ultrasonic scalpel.Results All operations including unilateral partial thyroidectomy(n=4),unilateral subtotal thyroidectomy(n=2) and bilateral subtotal thyroidectomy(n=9)were completed successfully.The mean operation time was 46 minutes(range,30-65 minutes).The intraoperative blood loss was less than 10 ml,except 25 ml in one patient.No complications occurred except superficial Ⅱ degree skin burn in 2 patients.The mean postoperative hospital stay was 1.8 days(range,1-3 days).All the patients were followed up for 8-10 months and no recurrence was found.Conclusions Suprasternal mini-thyroidectomy is feasible and safe with certain cosmetic effects.

Objective To investigate the correlation between plasma homoeysteine (HCY) level and coronary-heart disease (CHD). Methods 117 patients with coronary heart disease (CHD group) and 50 healthy controls (control group) were involved in the investigation. Plasma total HCY level was measured with enzymatic cycling assay. According to the clinical types, CHD cases were divide dinto stable angina pectoris (SAP) group (n = 35), unstable angina pectoris (UAP) group (n = 39) and acute myocardial infarction (AMI) group (n=43). Based on coronary angiography, the CHD cases were further divided into single-vessel (n = 31 ), double-vessel (n = 40) and triple-vessel (n = 46) groups. Results 1 ) Plasma HCY level was significantly higher in CHD group than that in control group (P<0. 01). 2) Plasma HCY level was associated with clinical types, higherst in AMI group, followed by that of UAP group, SAP group, healthy control group. There was statistical difference of HCY level between SAP group and UAP group, SAP group and AMI group, UAP group and AMI group (P<0. 01). 3) Plasma HCY level was gradually elevated in single-vessel, double-vessel and tri- ple-vessel group. There was statistical difference of HCY level between single-vessel group or double- vessel group and triple-vessel group (P<0.01). There was significant difference between single-vessel group and double-vessel group (P>0.05). Conclusion Plasma HCY level is elevated in patients with CHD, and elevated HCY is associated with increased number of stenotic coronary arteries. As a risk factor for CHD, HCY is closely associated with the occurrence and development of CHD.

Objective To study the effects and the mechanism of exogenous carbon monoxide on apoptosis of rat intestinal cells during endotoxemia. Methods The experimental rats were divided into 6 groups:control group, LPS(lipopolysaccharide: 5 mg/kg) group, CO inhalation(250?10~ -6) group, CO intraperitoneal injection(2 ml/kg) group, LPS(LPS 5 mg/kg) with CO inhalation(250?10~ -6) group and LPS(LPS 5 mg/kg) with CO intraperitoneal injection(2 ml/kg) group. The PaO_2, PaCO_2, SO_2 and COHb were monitored by blood gas analysis. The rat intestine malondialdehyde(MDA) was determined by thiobarbitric acid method and superoxide dismutase(SOD) was determined by hydroxylamine method after the rats were treated for 1, 3 and 6 hours. We also checked the apoptosis ratio of intestinal cells with flow cytometry(FCM). We also monitored the pathological changes with HE staining. Results Low concentration CO(250?10~ -6) inhalation and CO intraperitoneal injection(2 ml/kg) did not cause hypoxia. Comparing to control group and endotoxemia group,the intestineal MDA of the endotoxemic rats decreased after exposure to exogenous CO and the SOD activation increased. The apoptosis ratio of intestinal cells decreased after exposure to exogenous CO. On the apoptosis of endotoxemia rat intestinal cells, the effect of CO intraperitoneal injection was earlier than that of CO inhalation, but the effect of CO inhalation last longer. Conclusion Low concentration CO(250?10~ -6) inhalation and low dose CO(2 ml/kg) intraperitoneal injection were safe to rat. Exposure to exogenous CO could protect rat intestine against endotoxemia by inhibiting the apoptosis of intestinal cells. The effect of intraperitoneal CO injection was earlier than that of CO inhalation, but the effect of CO inhalation could last for longer than intraperitoneal CO injection.

AIM: To observe the effects of norepinephrine (NE) on the cardiopulmonary and lung injury in goats with acute respiratory distress syndrome (ARDS) induced by endotoxin. METHODS: A model of septic ARDS was induced by intravenous infusion of low dose endotoxin in six goats. Then 40?10~ -6 NO inhalation was applied to the animals. After 30 min, combined intravenous infusion of NE at concentration of 0.5 mg?kg~ -1 ?min~ -1 was conducted. The dynamic changes in gas exchange and hemodynamics were measured with the aid of Swan-Ganz catheter. Arterial blood gas analysis before and after the onset of ARDS, 30 min after NO inhalation and combined NE was detected. Histology of the lung was also observed. RESULTS: Inhalation of NO rapidly reduced mean pulmonary arterial pressure (MPAP), increased PaO_2, decreased P_ (A-a) O_2 and Qs/Qt in septic ARDS goats. These decrease and increase were more significant than those in NO inhaled alone when animals received NE. The combination of NO inhalation and NE injection resulted in increase in mean arterial pressure. NO inhalation did not ameliorate lung injury and combined NE intravenous injection ameliorated lung injury. CONCLUSION: Injection of low dose norepinephrine improves the beneficial effects of inhaled nitric oxide on lung gas exchange and ameliorates lung injury in goats with acute respiratory distress syndrome induced by endotoxin.
