Objective To explore influence of out-hospital health education on life quality of senile patient with acute myocardial infarction (AMI) after underwent stenting therapy of coronary artery.Methods A total of 100 cases of AMI patients undergoing stenting therapy of coronary artery were selected and randomly divided into the follow-up group and control group with 50 cases in each group. Patients of the follow-up group accepted out-hospital health education. While patients of the control group were only carried out conventional in-hospital health education. The quality of life of two groups was compared.Results At the end of study, the follow-up group had a better life quality than the control group ( P<0.01). The satisfactory degrees of nurse-patient relationship in the follow-up group were better than that of control group ( P<0.05).Conclusion Out-hospital health education can improve life quality of senile patient with AMI after underwent stenting therapy of coronary artery.

ObjectiveTo compare the health-related quality of life (HRQOL) of patients with or without coronary artery disease (CAD) and also to determine the factors affecting their quality of life.MethodsOne hundred patients with CAD and 100 patients without CAD were included in this cross-sectional study. The patients with CAD and the patients without CAD were matched by age, sex, marital status, and income. HRQOL was measured with the generic HRQOL instrument.ResultsHRQOL scores of the patients with CAD differed significantly from the patients without CAD. Compared to the patients without CAD, the HRQOL of the patients with CAD was lower in the dimensions of mobility, hearing, breathing, elimination, usual activities, mental function, discomfort and symptoms, vitality, and sexual activity. The patients with CAD had lower HRQOLscores than the patients without CAD. In the patients with CAD, age and sex independently affected the HRQOL. Older patients and women had worse HRQOL.ConclusionCoronary artery disease negatively affects HRQOL. It is thought that interventions to increase quality of life the patients with CAD may improve their HRQOL.

Objective To evaluate non operative and simple operative managements of the calcaneal fractures. Methods 97 patients with calcaneal fractures were treated by non operative management or percutaneous reduction with wires or screw fixation from April 1997 to December 2001 in our department. They were followed up for more than 2 years. 64 patients were treated with non operation, 27 were fixed with wires and 6 with screws. Results 23 patients had excellent results, 67 good, 5 fair and 2 poor. The total good and excellent rate was 92.7%. 2 patients experienced secondary arthrodesis 1 year after injury. Conclusion Although the calcaneal fractures can be treated satisfactorily with non operative management or percutaneous reduction with wires or screws fixation, further prospective and comparative studies should be done in clinic to determine whether the calcaneal fractures should be treated with open reduction and fixation or with simple operative management.

There are many factors which can affect the quality of graduate student education,such as management,tutors,and individuals,which are usually the main aspects.Scientific management is the essential factor for high quality of education.This article introduced the experiences of graduate education in Capital Medical University,and discussed some problems which should be coped with.

With the popularization and internationalization of higher education,the quality of higher education has been more and more attented to. The article has reviewed the overseas system of evaluation of graduate education,discussed the system in China,and advanced some suggestions on self-evaluation of graduate education in China.

Objective To explore the surgical safety and clinical efficacy of combined anterograde and retrograde method exposing porta hepatis for the treatment of the intrahepatic cholangiocarcinoma invading porta hepatis.Methods The retrospective descriptive study was conducted.The clinicopathological data of 3 patients with left intrahepatic cholangiocarcinoma invading porta hepatis who were admitted to the Renji Hospital affiliated to Shanghai Jiaotong University School of Medicine from February 2015 to May 2016 was collected.All the 3 patients underwent left hemihepatectomy combined with caudate lobectomy after preoperative lab and imaging examinations and the evaluations of liver function and residual liver volume.The surgical procedures followed as:anterograde dissection of porta hepatis,exposure of hilar plate,left hemihepatectomy combined with caudate lobectomy,right artery resection and reconstruction,hilar cholangioplasty and bilioenteric anastomosis.Observation indicators included:(1) surgical situations:operation time,time of hepatic artery~ anastomosis and volume of intraoperative blood loss;(2) postoperative pathological examinations;(3) postoperative situations:postoperative complications (biliary fistula,hemorrhage,abnormal liver function,gastroplegia) and postoperative chemotherapy;(4) follow-up:postoperative patients' survival and carcinoma occurrence.Follow-up was performed to by outpatient examination up to December 2016.The follow-up included clinical symptoms such as abdominal pain,chills,fever and jaundice,liver function and tumor marker examination,and color ultrasound Doppler or abdominal enhanced computed tomography (CT) was performed to detect carcinoma recurrence.Measurement data was represented as average (range).Results (1) Surgical situations:all the 3 patients underwent successful left hemihepatectomy combined with caudate lobectomy using combined antegrade and retrograde method exposing porta hepatis,including 1 combined with right hepatic artery resection and reconstruction,without perioperative death.The average operation time,average time of hepatic artery anastomosis and average volume of intraoperative blood loss of 3 patients were 493 minutes (range,430-570 minutes),11 minutes and 526 mL (range,450-600 mL),respectively.(2) Postoperative pathological examination showed 3 patients were diagnosed with cholangiocarcinoma,2 with nerve bundles invaded and 2 with No.12 lymph node metastasis,with negative margins of bile duct and hepatic artery.(3) Postoperative situations:3 patients are not complicated with biliary fistula and gastroplegia.One patient with postoperative liver dysfunction after right artery resection and reconstruction underwent anti-infection,hepatoprotection and anti-hepatic encephalopathy therapies,and then was improved and discharged from hospital at 4 weeks postoperatively.The other 2 patients recovered steadily without complications such as hypohepatia,and then respectively discharged from hospital at 17 and 20 days postoperatively.All the 3 patients underwent chemotherapy of gemcitabine combined with S-1 for 8 courses at week 4 or 5 postoperatively.(4) Follow-up:all the 3 patients were followed up for 7-20 months,with good general conditions and normal liver function and without cholangitis symptoms.One patient received right artery reconstruction,and CT reexamination at postoperative month 3 showed fine imaging of right hepatic artery.There was no sign of carcinoma recurrence.Conclusion The combined anterograde and retrograde method exposing porta hepatis for the treatment of the intrahepatic cholangiocarcinoma invading porta hepatis can increase the radical resection rate and surgical safety.

With the rapid development of pharmacogenetics, more and more studies have shown evidence in the association between polymorphisms at the human leukocyte antigen (HLA) loci and severe adverse drug reactions (SADRs). Several HLA-B alleles proved to be associated with SADRs for drugs such as carbamazepine, allopurinol, lamotrigine, and lfucloxacillin. hTe USA Food and Drug Administration (FDA) has even recommended routine screening for HLA-B allele before the use of abacavir and carbamazepine. With the completion of human genome project and the Hapmapproject, several new pharmacogenetics approaches such as genome-wide association study (GWAS) have emerged. hTese newly developed methods will undoubtedly accelerate the identiifcation and clinical utilization of the pharmacogenetic biomakers. In addition, the immunogenetic mechanisms by which the HLA alleles cause SADRs are explored at the cellular and molecular level. hTis review focuses on the recent progresses in HLA alleles and ADRs regarding both the clinical translation and modern pharmacogenetic methods.
