Oxyfedrine (Oxy ) exhibited inhibitory effect on washed rabbit platelet aggregation and MDA production induced by thrombin (4 U /ml) . The concentration of Oxy causing 50% inhibition of platelet aggregation induced by thrombin was 254 ?mol/L . Up to 2 nig/ml, acetysalicylic acid (ASA) could not antagonize platelet aggregation induced by thrombin 。 However, ASA 50 ?g/ml reduced the generation of MDA markedly. These results suggest that anti-aggregation of Oxy may be related to inhibition of PAF formation and the effect of Oxy on MDA generation may be due to the inhibition of arachi-donic acid release.

Objective To study the CT manifestations of metastatic lymph node of thyroid carcinoma. Methods CT appearances of metastatic lymph node of thyroid carcinoma proved by surgery and pathology in 108 patients were reviewed. Results Of these 108 cases, metastatic lymph nodes were located at superoir and middle internal jugular chain(n=76), inferior internal jugular chain and super clavicular region(n=86), tracheoesophageal groove(n=52), and superior mediastinum(n=17). Of 84 thyroid papillary carcinoma patients, the attenuation of metastatic lymph nodes were similar to that of normal thyroid gland(n=16), with cystic formations (n=24), intracystic high attenuation papillary-like nodules (n=18), and fine granular calcifications (n=11). Of 24 follicular carcinoma, medullary carcinoma, and clear cell carcinoma patients, 17 cases had significant homogeneous or heterogeneous enhanced nodes, and the attenuation was the same as primary or recurrent thyroid tumors. Conclusion For thyroid carcinoma, the most common locations of metastatic lymph nodes were internal jugular chain, tracheoesophageal groove, and superior mediastinum regions. Marked enhancement similar to normal thyroid gland, cystic formations with intracystic high attenuation papillary-like nodules, and fine discrete granular calcifications were the characteristic manifestations of metastatic lymph node of papillary carcinoma. Marked homogeneous or heterogeneous enhancement after contrast administration and the same attenuation as the primary or recurrent thyroid tumor were found in follicular carcinoma, medullary carcinoma, and clear cell carcinoma metastases.

OBJECTIVETo compare the efficacy between elongated needle therapy and regular needle therapy at Tiantu (CV 22) on the basis of xingnao kaiqiao (activiting brain and regaining consciousness) acupuncture therapy so as to explore the effective therapeutic method in treatment of dysphagia induced by bulbar palsy.

METHODSSeventy one cases of dysphagia induced by bulbar palsy were randomized into two groups. The xingnao kaiqiao acupuncture therapy was applied at Shuigou (GV 26), Neiguan (PC 6), Sanyinjiao (SP 6) and the others in the two groups. In the elongated needle therapy group, on the basis of xingnao kaiqiao acupuncture therapy, the elongated needle was used to puncture Tiantu (CV 22). In the regular needle therapy, the regular acupuncture technique was used at Tiantu (CV 22). In both groups, the treatment was given once a day in a week except Sunday and lasted for 4 weeks totally. Before and after treatment, the swallowing condition and the standardized swallowing assessment (SSA) were observed in the patients and the efficacy was compared between the two groups.

RESULTSThe total effective rate was 97.2% (35/36) in the elongated needle therapy group, which was better than 77.1% (27/35) in the regular needle therapy group (P<0.05). After treatment, SSA score was reduced significantly as compared with that before treatment in the two groups (both P<0.05). SSA score in the elongated needle therapy group was reduced much more apparently as compared with that in the regular needle therapy group after treatment (P<0.05).

CONCLUSIONOn the basis of the xingnao kaiqiao acupuncture therapy, the elongated needle therapy at Tiantu (CV 22) achieves the superior effect on bulbar palsy-induced dysphagia as compared with the regular acu- puncture at Tiantu (CV 22).

Objective To evaluate the role of via-anal ileus tube drainage in the therapy of acute low colorectal obstruction caused by cancer in elderly patients.Methods Totally 31 elderly patients with acute obstruction caused by colorectal cancer were treated by this modality.With the help of colonscopy and radiograph,the ileus tube was inserted into the proximal bowel of the obstructive side via anus.Then we irrigated and drain through the tube.At the same time we observed the patients' symptoms,abdominal girth,plain abdominal radiograph.After the relief of the acute obstruction,operations were processed.Results After 7-14 days treatment,the acute obstruction was relieved and emergency operation was avoided.The cure rate of 1-staged resection was 93.5％ (29/31),the rate of 1-staged anastomosis was 68.9％ (20/29),the rate of complication was 19.4％ (6/31),no anastomotic leakage and no perioperative death occurred.Conclusions The via-anal tube drainage in the treatment of the elderly patients with acute obstruction is safe,effective,and the trauma is small.It would be the first choice to relieve the acute obstruction in future.

Aim To investigate the protective effect of pituitary adenylate cyclase activating polypeptide(PACAP)on focal cerebral ischemia reperfusion injury in rats.Methods The models of focal cerebral ischemia reperfusion in rats were established with suture-occluded method to simulate the middle cerebral artery ischemia reperfusion injury in clinic.The treatment groups were given three different dose PACAP(PACAP 10-11 mol,PACAP 10-10 mol and PACAP 10-9 mol) in 15 minutes before cerebral ischemia.PACAPs were infused into lateral cerebral ventricle by microinjector.The water content of brain,the activity of superoxide dismutase(SOD),the content of malondialdehyde(MDA) and the content of nitrogen monoxidum(NO) of the brain tissue were determined.Results Compared with NS group,the water content of brain and the concentration of MDA and NO were obviously lower in each PACAP treatment group,while the activity of SOD was elevated to different degrees.Conclusion PACAP has an obvious protective effect on ischemia-reperfusion injury of focal brain tissue in rats,in which edema-alleviating,free radicals-scavenging and lipid peroxidation-attenuating could be involved.The protective effect seems to be more clear in middle-and high-dose group than in low-dose group.
