OBJECTIVE:To investigate the situation of adverse drug reactions(ADR) in our hospital.METHODS:In this retrospective study,a total of 270 ADR cases reported between 2005 and 2007 in our hospital were analyzed statistically in respect of the age and sex of patients,drug categories and clinical manifestations etc.RESULTS:Of the 270 ADR cases,patients aged ≤18 years or ≥50 years took the highest proportion(51.1% for the two age groups).The ADR were chiefly manifested as lesion of skin and its accessories,followed by the reaction of digestive system.90.74% of the ADR cases were induced by injections,and 191 cases(70.74%) were induced by antibiotics.CONCLUSION:ADR worth the highest alert in the clinic.

Objective To investigate the expression of β-catenin and PCNA,and its relationship with clinical parameters and prognosis.Methods Tissue microarray technology and immunohistochemical method were used to detect the expression of β-catenin and PCNA in gastric carcinoma and normal tissue collected from January 2000 to December 2006.Data were analyzed by SPSS 19.0.Results The percentage of expression of β-catenin and PCNA in gastric carcinoma is 96.7％,99.2％,respectively,and higher than the normal gastric tissue (x2 =41.082,P =0;x2 =97.692,P =0).ROC curve was used to find that PCNA was better than β-catenin to discriminate gastric carcinoma from normal gastric tissue in sensitivity,specificity,coincidence rate(84.4％,87.5％,84.6％).The expression of β-catenin is related to lymph node metastasis in gastric cancer (x2 =6.107,P =0.04).The expression of PCNA is related to pathological type (x2 =9.71,P =0.02).The expression of β-catenin and PCNA in gastric carcinoma were positively correlated (r =0.24,P =0.005).Multivariate analysis showed that TNM staging and both positive β-catenin and PCNA were independent factors impacting on the overall survival rate of patient with gastric cancer.Conclusions The expression of β-catenin and PCNA in gastric carcinoma is signifrcandy high.PCNA is more important than β-catenin in discriminating gastric carcinoma from normal gastric tissue.Combined detection of the two kinds of protein have some clinical significance in predicting the prognosis of patients with early gastric cancer.

ObjectiveTo prospectively investigate the feasibility of contrast material-enhanced magnetic resonance angiography(CE-MRA)for visualization of the spinal vasculature.MethodsTen volunteers and fifteen patients with thoracic or lumbar disk herniation underwent contrast-enhanced MR angiography of the thoracoabdominal aorta and posterior branches.Examination Was performed with three-dimensional CE-MRA technique and 0.3 mmol/kg of gadolinium contrast agent Was administrated.ResultsIn all examinations,the Adamkiewicz artery,the anterior spinal artery(ASA),and their connections witll the aorta were identified.The Adamkiewicz artery originated between T8 and L3 in all examinations and derived from the left side of the aorta in 80% of all examinations.ASA was able to be observed from T6 to L3.The diameter of Adamkiewicz artery Was 0.6-1.2 mm and ASA was 0.6-1.0 mm.Conclusion CE-MRA Can be used to lOCalize Adamkiewicz artery and provide accurate information for clinical approach.

Objective To evaluate the diagnostic value of deep venous thrombosis(DVT)on lowerlimb venous ultrasonography combined with right ventricular dysfunction (RVD) on transthoracic echocardiography(TTE) in patients with acute pulmonary thrombo embolism(PTE). Methods This prospective multicenter control trial included 520 patients with confirmed acute PTE from 41 hospitals between June 2002 and February 2005.Results The incidence of RVD and DVT was associated with the severity of PTE.There were 57.0%(207/363)patients with RVD,49.6%(1 80/363)patients with DVT,265(73.0%)patients with RVD and/or DVT,and 121(33.3%)patients with combined sign of DVT plus RVD in the whole population.As to major PTE population,206(99.5%)patients had RVD and 121 (58.5%)patients had DVT.In addition,the rate of RVD was much greater in proximal PTE than in lobar PTE and segmental PTE(78.7%,51.4%and 21.7%,respectively,P＜0.001).DVT occurred more frequently in proximal PTE than in lobar PTE and segmental PTE(61.7%,46.8%and 37.0%,respectively,P＜O.001).The incidence of the combined sign was 51.1%,24.3%and 8.7%,respenctively (P＜0.001).Conclusions The incidence of the combined sign of RVD plus DVT was associated with the severity of PTE and the localization of emboli.The combined sign of RVD plus DVT help diagnose major PTE especially in emergency department.

ObjectiveTo investigate the effect of MK-801 on levodopa-induced dyskinesia (LID)in Parkinson' s disease (PD). MethodsRat models ( n = 25) of Parkinsonism related motor complications were established and were randomly divided into levodopa-induced dyskinesia (LID) group (n = 10), MK801 treatment group (n = 10) and PD group (n =5). Another 5 rats were served as control group. The behaviors of LID rats treated with MK-801 were observed. Immunohistochemistry and Western blot analysis were used to determine the expression of β-arrestin1 in the striate of rats.Results After MK-801 treatment, abnormalinvoluntarymovementscores and peakturning weredecreasedin LIDrats.Immunohistochemistry showed that β-arrestin1-positive cells of the lesioned side ((2. 95 ± 0. 44) × 104) in LID rats were decreased compared to the contralateral side ( ( 3.78 ± 0. 37 ) × 104, t = 5. 415, P ＜ 0. 05 ).Western blot showed that the levels of β-arrestinl in PD group ( presented as lesioned side/contralateral side) were ( 81.02％ ± 2. 23％ ). The levels of β-arrestin1 (64. 88％ ± 3. 10％ ) were deceased in LID rats compared to PD rats ( t = 9.47, P ＜ 0. 01 ). However, the levels of β-arrestin1 ( 89. 26％ ± 1.90％ )were increased in MK-801-treated rats (t = 14. 82, P ＜0. 01). ConclusionsMK-801 reduces LID in PD rats. The beneficial effect of MK-801 may be mediated through the increased expression of β-arrestinl which in turninhibits the overactivation of glutamate receptors.

Objective To identify the biomarkers which can be used of estimating the biological behaviors of prostate cancer with osseous metastasis by SELDI-TOF-MS. Methods Screening for potential tumor biomarkers of serum samples from 19 prostate cancer patients and 35 prostate cancer patients with osseous metastasis by using the technology of SELDI-TOF-MS and CM 10 protein chips (Ciphergen Inc. USA).The PBS Ⅱ protein chip reader was used to analyze the CM10 protein chips and transform the protein information into the form of spectra. The protein contents of two groups in the same mass-to-charge ratio (M/Z value) were analyzed and preceded the analysis of variance by Biomarker Wizard software. The proteins whose contents in serum were significantly different, which was distinguished the correctly groups by Biomarker Pattern software. Results The contents of 4 proteins in the two groups were significantly different and the M/Z values of these 6 proteins were from 2000 to 20 000. The relative protein content of prostate cancer patients group was higher than that of Prostate Cancer patients with osseous metastasis group at the M/Z value of 2089,4281, 3507 and 4178 [(4.63±8.03) vs (9.88±10.77), (19.78±21.46) vs (26.73±19.41), (5.46±10.14) vs (8.10±8.74), (38.01 ±26.27) vs (45.25±20.40), (P＜0.05)]. The relative protein content of prostate cancer patients group was lower than that of prostate cancer patients with osseous metastasis group at the M/Z value of 15 900 and 16 081 [(11.52±16.80) vs (4.84±5.83), (8.55±12.64) vs (3.56±3.90), (P＜0.05)]. Conclusion The associated serum protein in prostate cancer with osseous metastasis can be quickly and exactly diagnosed by SELDI-TOF-MS with high sensitivity and specificity. This new method will be widely used in clinical application.

Objective To analyze the treatment effect of deep venous thrombosis (DVT) in acute pulmonary thromboembolism (PTE) with thrombolytic and anticoagulant therapy. Methods Post hoc analysis of data from a prospective multicenter randomized control thrombolytic and anticoagulant trial of 516 patients with acute symptomatic PTE from June 2002 to December 2004. Thrombolytic therapy was performed in patients with massive and sub-massive PTE and anticoagulant therapy was given in patients with non-massive PTE. A total of 362 patients that accepted compression uhrasonography (CUS) before and 14 days after treatment constituted this study. Results The ratio of detected DVT by CUS 14 days after treatment was reduction than that before treatment ( x2 = 22. 667, P < 0. 001 ), but 11.6% patients had new or recurrent DVT. The rates of recanalization in thrombolysis group and anticoagulant group were 56. 5% and 47. 8% respectively (x2 = 1. 435 ,P =0. 231 ). The results after three months follow up showed not recovery in 30. 4% DVT patients and new or recurrent DVT in 10. 4% patients. Conclusions The normalization rate of DVT is low during 14 days treatment, and recurrence rate is high. Thrombolysis has no better rate of recanalization than anticoagulant. The prognosis of DVT hasn't improved significantly during short term treatment.

Objective:To review literature reports of varieties of ADRs induced by mebendazole to provide a sci- entific foundation for clinical revaluation of mebendazole.Method:The related literatures in the internal and external medi- cine medical database in 1994-2004 were explored,and then both analysis and statistics were conducted with the methods of epidemiolngy and literature analysis.Result:ADRs induced by mebendazole could be involved in multiple organs.Most victims were children and the elderly.Their latent periods were determined by the types of ADRs,which had a variety of forms.Conclusion:Mebendazole was potentially unsafe.So we should strengthen our rational drug use and post-marketing revaluation of safety.

OBJECTIVE: To provide information for clinical rational and safe use of albendazole.METHODS: The medical database and network both at home and abroad were searched and the data regarding the research and development,the market information and indications of albendazole were analyzed.RESULTS & CONCLUSIONS: 5 dosage forms of albendazole are available in the market: tablets,capsules,granules,oral liquid,and syrup.The sales amount of albendazole in recent years dominated the first 3 places in domestic antiparasites market.There are a total of 39 domestic manufactures for albendazole,which can be used to treat 21 kinds of human parasitosis.Its clinical application is widespread.However,severe adverse drug reactions such as the rare encephalitis syndrome and allergic shock etc induced by albendazole pose hidden risks for treatment;therefore,management on its use should be strengthened.
