RESUMO
Objective To investigate correlation between seizures and uric acid level in the hippocampus in a mouse model with acute limbic seizures by pharmacological and genetic method. Methods Normal male C57BL/6 and mutant mice were used in this study,including urate oxidase overexpression (UOx-OE) and urate oxidase knock-out (UOx-KO) ;These mice were divided into the following groups,including the control,KA, All ,OE ,KO group respectively;during the experiment ,behaviors ,latency and duration time were recorded;dialysates were collected by microdialysis technique and uric acid level was detected by FPLC;Uric acid in the hippocampus,seizures status,latency and duration were compared. Results Twenty-four mice in total were enrolled and only 1 death occurred until the end of the study. Seizures state appeared after KA treatment. Compared to the KA group,uric acid and generalized seizures declined by the treatment of KA and All (P 0.05). Conclusions Uric acid level in the hippocampus of mice may have effects on seizures ,in which it suggests that uric acid and its relevant signal pathway could be a potential therapy target in seizures clinically.
RESUMO
OBJECTIVE:To investigate the influential factors of adverse drug reaction(ADR)in elderly patients during medi-cation,and to provide reference for reducing the incidence of ADR in geriatrics department. METHODS:The clinical data of elder-ly patients admitted to our hospital from Jan. 2011 to Dec. 2015 were collected and analyzed by single factor and unconditional Loigstic multiple regression analysis. The risk influential factors of ADR were investigated. RESULTS:A total of 1 680 patients re-ceived drug therapy,and the incidence of ADR was 7.92%(133/1 680). Organs/systems involved in ADR were mainly allergic re-action(49 cases,36.84%)and digestive system(48 cases,36.09%). The results of single factor analysis showed that the age of patients,drug dosage,route of administration,treatment course,the type numbers of drug combination and others were the inde-pendent influential factors of ADR. By unconditional Loigstic multiple regression analysis,it was found that the risk of ADR in-creased with the drug dosage,treatment course,intraverous administration and various drugs use,etc. CONCLUSIONS:It is nec-essary to pay attention to ADR monitoring,particularly risk factors monitoring of ADR in the elderly patients,strengthen medica-tion guidance to improve medication compliance,take the necessary preventive measures to reduce the incidence of ADR.
RESUMO
Objective To compare the clinical efficacy of the nerve bow (digital nerve and cutaneous antebrachii later-als) with end-to-side neuroanastomosis and traditional end-to-end neuroanastomosis for repairing bilateral proper digital nerve inju-ries while replanting injured fingers. Methods A total of 57 patients with bilateral proper digital nerve injuries from March 2009 to September 2012 were retrospectively analyzed. The patients were divided into three groups according to different treatments:19 patients underwent nerve graft bow end-to-side neuroanastomosis. During operation, a cutaneous antebrachii laterals nerve was freed and obtained from the homolateral forearm, which were sutured with bilateral distal digital nerve end to end, then nerve bow was formed. The bilateral proximal ends of digital nerve were sutured end-to-side bow, respectively. 22 patients underwent digital nerve bow end-to-side neuroanastomosis. During operation, bilateral distal ends and proximal ends were sutured respectively;con-sequently, the distal and proximal nerve bows were formed. A cutaneous antebrachii laterals nerve was obtained from the homolat-eral forearm, then divided equally to 2 parts which were used to bridge the 2 nerve digital nerve bow end-to-side neuroanastomosis bows. 16 patients underwent nerve graft with end-to-end neuroanastomosis. The sensation of finger plup, two point discrimination and motion of joints were evaluated. Results All patients achieved primary healing of wound after operation, with 57 fingers re-covered uneventfully. In nerve graft bow end-to-side neuroanastomosis group, 18 patients were followed up for 3-15 months;the average result of sensation measurement was S3+;the average result of two point discrimination was 5.1±0.8 mm. In digital nerve bow end-to-side neuroanastomosis group, 19 patients were followed up for 4-15 months;the average result of sensation measure-ment was S3; the average result of two point discrimination was 6.3 ± 0.9 mm. In nerve graft with end-to-end neuroanastomosis group, 12 patients were followed up for 3-14 months;the average result of sensation measurement was S2, the average result of two point discrimination was 7.2±1.4 mm. According to total active motion scales, there had no difference in results of motion of joints in the 3 groups. Conclusion The nerve bow end-to-side neuroanastomosis is valuable method for repairing bilateral proper digi-tal nerve injuries at the same time, which can restore sensation of fingers.
RESUMO
Objective To explore the expression and significance of HDGF and ADAM9 in esophageal cancer.Methods HDGF and ADAM9 expression in 113 patients with esophageal cancer (78 males and 35 females) with ages ranging from 28 to 87 years,averaged (61.2 ± 8.6) years,were analyzed by SP immunohistoehemical staining.Results The positive rates of HDGF and ADAM9 in esophageal cancer (78.8％ and 68.1％ respectively) were significantly higher than those in normal tissue(all were 30％).ADAM expressions were not correlated with age,sex,tissue types,lymph nodes metastasis,location and tumor size (P ＞ 0.05) ;the positive expression rate of HDGF and ADAM9 was related to differentiation,PT stages,and 5-year survival rate (P ＜0.05).HDGF was correlated with PT stage.Conclusion The expressions of HDGF and ADAM9 in esophageal cancer tissues were more higher than normal esophageal tissues,this means they could promote the development of tumor cells transformation,multiple and moving,and may be an useful tool for providing information about the targeted therapy and prognosis.
RESUMO
Objective To investigate the relationship between the expression of MMP-10 and the invasion and metastasis in esophageal cancer. Methods The expression of MMP-10 and mean microvessel density (MVD) in 54 specimens were examined by immunohistochemical stain. Results The MMP-10 expression in the tumorous tissue was significantly correlated with lymph node metastasis, invasionand TNM stage(P
RESUMO
Argyrophilic nucleolar organizer region proteins were determined in 50 patients with squmous cell carcinoma of esophagus by argyrophilic technique. Pathological sections of the tissue of the resected specimens were examined. The results showed that the AgNOR content was corelated with the lymph node metastasis rale, histologic grading of the CA and the postoperative prognosis. The higher the AgNOR content, the higher lymph node matastasis rate(P
RESUMO
Objective To study the expression and clinical significance of anty-apoptosis protein BAG-1 in non-small cell lung cancer(NSCLC),and its relationship with cell apoptosis and expression of Bcl-2 protein. Methods Immunohisto chemistry streptavidin-peroxidase conjugated (SP)method was used to examine the expression of BAG-1protein and Bcl-2 protein,and terminal deoxynucleotidyl transferase mediated UTP nick end labeling(TUNEL) method was used to examine the apoptosis index in 54 cases of NSCLC.The expression of BAG-1 protein in 20 cases of normal bronchus mucosa tissue also be detected as control. Results Express positive rate of BAG-1 protein in NSCLC is 74.07%,obviously higher than that in normal bronchus mucosa tissue(positive rate is 5%).In cases of NSCLC,the expression of BAG-1 protein has not correlation with the age,gender,pathologic classification,but have closed correlation with lymph node metastasis,degree of differentiation,pTNM stage(P
