Objective To study clinical feature of diagnosis of pancreatic cancer,in order to reach early diagnosis.Methods 70 cases of pancreatic cancer from ours in-patients 1990 to 2000 were reviewed and analyzed.Results The number of patients with stage Ⅰ～Ⅱ were only 8 cases(11 4%). 40 patients (57 1%) hospitalized within one month after they felt ill.19 cases(29 1%) were diagnosed as pancreatic cancer within one month,including 5 patients(26 3%) with stage Ⅰ or Ⅱ .Abdominal pain(73 4%),jaundice(10 1%) and discomfort of upper abdominal(5 8%) were the most common initial symptoms.misdiagnosis were 40(57 1%) cases .The most common misdiagnosis were chronic gastritis(21 4%),chromic cholecystitis(7 14%) and peptic ulcer(5 71%).The serum levels of CA199,CA125 were higher in 16/18 cases (88 9%) and 6/7 cases (85 7%) respectively. Three cases in stage I or II were found higher serum CA125 and other tumor marker normal.Five patients were diagnosed as diabetes within five months before the diagnosis of the cancer.Conclusions For most of the patients with pancreatic cancer ,usually they were definite diagnosis in moderate or advanced stage. So the status of the diagnosis of pancreatic cancer is disappointed . Hospitalizing late,being misdignosed and developing quickly were the main causes;The most common misdiagnosis are chronic gastritis, cholecystitis and peptic ulcer;elevation of serum CA199 and CA125 are sensitive to diagnose pancreatic cancer. Detections of CA125 and hyperglycemia may favour earlier diagnosis of pancreatic cancer.

objective: To investigate the status of empathy ability and perceived social support in military college students, and to explore the relationship between empathy ability and perceived social support. Methods: A total of 472 college students were selected from 5 military academies. The Interpersonal Reactivity Index-C (IRI-C) and Perceived Social Support Scale (PSSS) were used to evaluate the empathy ability and the perceived social support ability of military college students. Results: The total scores of IRI-C and PSSS were (51. 2 ± 10. 8) and (65. 8 ±11. 5), respectively. The total scores of PSSS and its three dimensions (family support, friend support and other support) were positively correlated with the total scores of IRI-C and its three dimensions (empathy concern, perspective taking and fantasy) (r = 0. 19-0. 35, Ps ＜ 0. 01). The scores of empathy concern and perspective taking could positively predict the total scores of PSSS (β = 0. 29, P ＜ 0. 001; β = 0. 15, P ＜ 0. 001). Conclusion: It suggests that the empathy ability of military college students is at the middle level. Empathy ability could predict perceived social support in military college students.

Objective:To systematically evaluate the influencing factors on unplanned shutdown of continuous blood purification, and to provide reference basis for the prevention of unplanned shutdown.Methods:The literatures related to the influencing factors of unplanned shutdown of continuous blood purification in CNKI, Wanfang Database, Chinese Biomedical Literature Database, Chinese Science and Technology Periodical Full-text Database, PubMed and Web of Science were searched.The retrieval time of Chinese database was from the establishment of the database to March 2021.English databases were searched from March 2016 to March 2021.Literature selection, quality evaluation and data extraction were independently conducted by two researchers, and Meta-analysis was performed by Stata 14.0 software.Results:A total of 11 studies were included, including 3 031 cases of continuous blood purification treatment and 1 412 cases of unplanned discontinuation.The combined OR value and 95% CI of all influencing factors were as follows: treatment mode 2.22 (1.06-4.62), blood flow velocity 0.91 (0.776-1.09), agitation 4.54 (2.33-8.86), ventilator 2.67 (1.63-4.38), transfusing blood products and fat milk 1.07 (0.34-3.36), one-time catheter success 0.26 (0.05-1.42), catheterization site (femoral vein vs.jugular vein) 2.24 (0.83-6.02). Conclusion:Unplanned deplaning is influenced by many factors.Treatment mode, agitation and ventilator use are the risk factors for unplanned deplaning.There is no correlation between blood flow velocity, transfusing blood products and fat milk, one-time catheterization success, catheterization site and unplanned deplaning.
