Objective To explore and evaluate the combined conservative managements in the treatment of cervical chylous leakage. Methods Thirty nine eases of cervical chylous leakage from Jun 1992 to Jun 2008 were retrospectively analyzed in this hospital. All of the 39 eases were cured by treating with conservative individualized therapy, including the applying of diet with high calory, high protein and low fat and fatty food should only contains medium-chain triglycerides, total parenteral nutrition, keep the balance of hydrogen and electrolyte and correct hypoproteinemia, local pressure dressing, high persistent vacuum drainage (- 50～ - 80 kPa) and/or somatostatin analogue. Results All the cases of chylous leakage happened 2nd to 5th days after the operation. Among the 39 cases, 7 were high flow (drainage ≥500 ml/d) chylous leakage, the amount of drainage reached as high as 1440 ml per day. The time of chylous leakage closure was 3～12 days, and the mean time was 7 days. No one experienced re-operation, wound hydrops or wound infection. Condusions The conservative individualized therapy may play a key role in the treatment of cervical chylous leakage.

Patient safety education is conducive to medical students' cognition on patient safety and to improvement of medical quality and safety. Developing patient safety education for medical students is more and more widely recognized by World Health Organization and countries all over the world. However, in China, patient safety courses aiming at medical students are relatively few, and there are few reports about the effect of patient safety courses. This paper explored the influence of patient safety curriculum on medical students' attitude to and knowledge of patient safety. The patient safety curriculum was carried out for 2011-grade undergraduates of Tongji Medical College, Huazhong University of Science and Technology. The students participated in the class according to free choice. After the curriculum, the information of gender, major, attended course, attitude toward patient safety, and knowledge of laws and regulations of the 2011-grade undergraduates were collected. After rejecting invalid questionnaires, the number of undergraduates that participated in the survey was 112 (61 students did not take part in the curriculum; 51 took part in). Chi-square test was applied to analyze patient safety education's influence on medical students' attitude to patient safety and their knowledge mastery situation. The influence of patient safety education on the attitude of medical students to patient safety was not significant, but that on their knowledge of patient safety was remarkable. No matter male or female, as compared with medical students who had not accepted patient safety education, they both had a better acquisition of knowledge after having this education (for male students: 95% CI, 4.556-106.238, P<0.001; for female students: 95% CI, 3.183-33.238, P<0.001). Students majoring in Western Medicine had a relatively better mastery of knowledge of patient safety after receiving patient safety education (95% CI, 6.267-76.271, P<0.001). Short-term patient safety education cannot change medical students' stereotyped cognition on matters related to patient safety, but it can effectively enhance their knowledge of laws and regulations of patient safety.

Background:Clinical outcomes of undifferentiated arthritis (UA) are diverse,and only 40 ％ of patients with UA develop rheumatoid arthritis (RA) after 3 years.Discovering predictive markers at disease onset for further intervention is critical.Therefore,our objective was to analyze the clinical outcomes of UA and ascertain the predictors for RA development.Methods:We performed a prospective,multi-center study from January 2013 to October 2016 among Chinese patients diagnosed with UA in 22 tertiary-care hospitals.Clinical and serological parameters were obtained at recruitment.Follow-up was undertaken in all patients every 12 weeks for 2 years.Predictive factors of disease progression were identified using multivariate Cox proportional hazards regression.Results:A total of 234 patients were recruited in this study,and 17 (7.3％) patients failed to follow up during the study.Among the 217 patients who completed the study,83 (38.2％) patients went into remission.UA patients who developed RA had a higher rheumatoid factor (RF)-positivity (42.9％ vs.16.8％,x2=8.228,P=0.008),anti-cyclic citrullinated peptide (CCP) antibodypositivity (66.7％ vs.10.7％,x2 =43.897,P ＜ 0.001),and double-positivity rate of RF and anti-CCP antibody (38.1％ vs.4.1％,x2 =32.131,P ＜ 0.001) than those who did not.Anti-CCP antibody but not RF was an independent predictor for RA development (hazard ratio 18.017,95％ confidence interval:5.803-55.938;P ＜ 0.001).Conclusion:As an independent predictor of RA,anti-CCP antibody should be tested at disease onset in all patients with UA.
