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.

Objective To investigate clinical relevance of the acute Stanford B aortic dissection vascular repair time for treatment and prognosis.Methods A retrospective clinical data of our hospital treated 1 10 cases of vascular repair of acute aortic dissection type Stanford B were analyzed according to the onset to treatment time.They were divided into three groups:group A (onset to treatment time of 7 days),group B (onset to treatment time 14) and group C (onset to treatment time than 14 days);the three groups were observed after aortic repair status and prognosis related indicators.Results The true lumen false lumen diameter and maximum diameter ratio in group A was the largest (1.8 ±0.5),which was significantly higher than that of group B and group C (1.3 ±0.3)and (1.3 ± 0.2),the difference was statistically significant (F=7.352,P<0.05).Ratio of preoperative minimum true lumen diameter and the maximum diameter of the false lumen,ratio of postoperative maximum true lumen diameter and the maximum diameter of the false lumen were associated with the onset of the endovascular repair time,showed a negative correlation (r=-0.452,-0.281,all P<0.05).postoperative complication rate of group A was 12.8%,complica-tion rate of group B was 29.5%,complication rate of group C was 33.3%,data of group A was significantly lower than those of group B and group C,the difference were statistically significant (χ2 =4.024,4.721,all P<0.05).group A died three cases,group B had 1 patient died and in group C there was no deaths.Hospital stay and hospital costs of group A were significantly lower than those of group B and group C,the difference werestatistically significant (F=4.125,7.375,all P<0.05).Conclusion As soon as possible to implement acute aortic dissection stanford B aortic vascular repair could better improve outcomes,and reduce the cost of hospitalization and treatment.At the same time, it can reduce the incidence of complications and improve clinical safety.

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.
