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).

· AIM: To investigate the influence of TGF-β 2 antisense oligonucleotide(ASON) on the differentiation, proliferation of stromal fibroblast in corneal stroma injury.both eyes of 28 rabbits, the right eyes were served as experimental group, corneal incisions were sutured with 8-0 coated vicryl suture carrying TGF-β 2 ASON; the left eyes were served as control group, corneal incision were sutured with common 8-0 coated vicryl suture. Rabbits were killed at 4, 7, 14 and 28d after surgery, stromal fibroblasts were examined by immune histochemistry and electron microscopy.significantly reduced the numbers of cells expressingα -smooth muscle actin (α -SMA) and proliferating cell nuclear antigen (PCNA). The ultrastructure of fibroblast had no significant difference in two groups.differentiation and proliferation of stromal fibroblast in corneal injury. This will be a new method to adjust corneal wound repair.

Objective To explore the effect of chronic low lead exposure on molecular pathological mechanisms of learning and memory of rats at the developmental stage Methods The changes of N methyl D aspartate receptor 1 (NMDAR 1) mRNA expression in rat hippocampus were observed by using digoxigenin labled anti sense oligonucleotide probes in situ hybridization technique Results The changes in NMDAR 1 mRNA levels in Pb exposed rat hippocampus were found to be dependent upon the developmental period of exposure and the region of the hippocampus analyzed Hippocampal NMDAR 1 mRNA levels increased significantly in the CA1 (18 75%) and CA3 (13 2%) ( P

Objective To investigate the preventive effect of oral ulcer using two methods in radio-therapeutic patients after tongue squamous cell carcinoma operation. Methods Thirty-six radiotherapeutic patients after tongue squamous cell carcinoma operation were collected from May 2012 to May 2014 and divided into control group and treatment group according to the random number table method. Regular oral nursing was administered to control group, treatment group were received regular therapy plus orally vitamin B and cetylpyridinium chloride gargle for gargling, and then evaluated the efficacy according related standards. Results Less oral ulcer (1/18 vs.7/18,χ2=-2.372,P<0.05), better oral lustration (Z=-2.093,P<0.05) and overall oral nursing effect (Z=-2.166,P<0.05) were observed in treatment group compared to control group after 7 days of therapy, however, treatment group presented no significantly better comfort level at the same time (Z=-1.708,P>0.05). Conclusions Regular therapy plus orally vitamin B and cetylpyridinium chloride gargle for gargling are effective for the prevention of oral ulcer in radiotherapeutic patients after tongue squamous cell carcinoma operation.

Objective To summarize the impact factors of extracorporeal shock wave lithotripsy (ESWL) in ureteral calculi patients.Methods The data of 287 patients with ureteral calculi from January 2010 to December 2012 in the Aerospace General Hospital of Beijing who received the ESWL were retrospectively analyzed.The relationship between ESWL' s effect and patients' gender, age, the stone' s size, the stone's location, the length of the course and the stone bed' s polyps hyperplasia was analyzed.Results The Partial correlation course and chi-square test showed that, there was statistically significant difference between the ESWL treatment effect and patient' s age, patient' s length of the disease course and patient' s stone size (P＜0.01).The value of OR between patient' s age and ESWL treatment effect was 1.905, showed that with the age of the patients increased every 10 years, the success rate of ESWL was reduced by 1.905 times.The value of OR between the patient' s length of the disease course and ESWL treatment effect was 2.809,indicated that with the duration of the course of prolonged every 1 month, the ESWL success rate decreased by 2.809 times.The value of OR between stone size and ESWL effect was 2.277, showed that the ratio between the stone diameter of 1.1-2.0 cm and 0.6-1.0 cm, the ESWL success rate reduced by 2.277 times.For the surgery patients who were failure to ESWL treatment,we found that there has statistical significance between the patients' length of disease course and stone bed' s polyps hyperplasia(P＜0.01), but the relationship between the stone bed' s polyps hyperplasia and the gender, the age, the stone' s position, the stone ' s size had no statistical significance (P ＞ 0.05) .Conclusion The patient ' s age, the length of the disease course, the stone ' s size and stone' s position are significantly affect to the effect of ESWL.There have closely relationship between the length of the disease course and the stone bed' s polyps hyperplasia, which is the reason why the longer length of the course, the worse the ESWL' s effect.This has very important instructed meaning for anticipating the treatment effect by the comprehensive evaluation of the patients before ESWL treatment.
