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).
