Background:With the deepening of researches on etiology of gastrointestinal bleeding,bleeding caused by pancreatic diseases has been understood better by the clinicians. Upper gastrointestinal bleeding (UGIB)is an uncommon but highly lethal complication of pancreatic diseases. Aims:To analyze the clinical characteristics of UGIB caused by pancreatic diseases for improving the diagnosis and management of this condition. Methods:A total of 22 inpatients who were diagnosed as UGIB caused by pancreatic diseases from Sep. 2010 to Sep. 2016 at Daping Hospital,the Third Military Medical University were recruited and analyzed retrospectively. Results:There were 15 males and 7 females;the disease was more prevalent in young patients than in middle-aged and elderly patients (45. 5% vs. 31. 8% and 22. 7%). The top five causes of bleeding were as follows:stress ulcer related to acute pancreatitis (36. 4%),pancreatic pseudocysts related to chronic pancreatitis (18. 2%),severe acute pancreatitis (13. 6%),post-operative bleeding related to pancreatic surgery (9. 1%)and left-sided portal hypertension (9. 1%). The diagnosis was commonly made by gastroscopy, abdominal contrast-enhanced CT and angiography. Ten patients received medical therapy only,6 were treated by surgical operation,5 by endoscopic hemostasis,and 1 by angioembolization. Hemostasis was achieved in 18 patients (81. 8%), and rebleeding occurred in 4 patients,of which two received medical therapy initially. Two elderly patients died of uncontrollable bleeding and multiple organ failure,respectively. Conclusions:UGIB caused by pancreatic diseases are prone to occur in young and middle-aged males. Pancreatitis and its complications are the major cause of this condition. Medical therapy is ineffective for most of the patients and a multidisciplinary approach of endoscopy,transarterial intervention and surgery is recommended.

The expression of human general control of amino acid synthesis protein 5 (hGCN5) in human Burkitt's lymphoma Daudi cells in vitro, effects of Trichostatin A (TSA) on cell proliferation and apoptosis and the molecular mechanism of TSA inhibiting proliferation of Daudi cells were investigated. The effects of TSA on the growth of Daudi cells were studied by 3-(4, 5-dimethyl-2-thiazolyl)-2,5-diphenyl-2H-tetrazolium (MTT) assay. The effect of TSA on the cell cycle of Daudi cells was assayed by a propidium iodide method. Immunochemistry and Western blot were used to detect the expression of hGCN5. The proliferation of Daudi cells was decreased in TSA-treated group with a 24 h IC50 value of 415.3979 microg/L. TSA induced apoptosis of Daudi cells in a time- and dose-dependent manner. Treatment with TSA (200 and 400 microg/L) for 24 h, the apoptosis rates of Daudi cells were (14.74+/-2.04) % and (17.63+/-1.25) %, respectively. The cell cycle was arrested in G0/G1 phase (50, 100 microg/L) and in G2/M phase (200 microg/L) by treatment with TSA for 24 h. The expression of hGCN5 protein in Daudi cells was increased in 24 h TSA-treated group by immunochemistry and Western blot (P<0.05). It was suggested that TSA as HDACIs could increase the expression of hGCN5 in Daudi cells, and might play an important role in regulating the proliferation and apoptosis of B-NHL cell line Daudi cells.

Objective To investigate the clinical characteristics of adult patients with community acquired pneumonia (CAP) caused by acute Mycoplasma pneumoniae (MP) infection, and provide evidence for early identification of MP infection. Methods A prospective, multicenter and cross-sectional study was conducted. 452 adult patients with CAP admitted to Beijing Friendship Hospital, Beijing Guangwai Hospital and Air Force General Hospital from August 2011 to October 2015 were enrolled. The diagnosis of adult MP infection was confirmed by the combined application of double serum antibody titer and MP-DNA nested polymerase chain reaction (PCR) through testing serum and throat swab samples from patients to identify acute infections, past infections, pathogen carrying, and non-MP infection. The clinical characteristics of patients with acute MP infection were summarized by analyzing the baseline data, clinical parameters and chest imaging findings in patients with non-MP infection and acute MP infection. Results Of 452 enrolling patients with CAP, 288 patients (63.7%) suffered from MP infection, and 164 patients (36.3%) with non-MP infection. There were 56 patients (12.4%) with acute infection, 10 patients (2.2%) with past infections, 222 patients (49.1%) with pathogen carriers in MP infective patients indicating susceptible to MP in adult patients. There were no significant differences in gender, age, fever extent, duration of fever, sputum production, shortness of breath, rales, underlying diseases, etc. between non-MP infection and acute MP infection patients, which suggested that the baseline data of the two groups were equilibrium. The acute infection rates of MP in summer and autumn (43.9% and 43.5% respectively) were more than those in spring and winter (13.3% and 12.3% respectively). It was shown by laboratory examination results that serum cardiac troponin T (cTnT) increased significantly in acute MP infectious patients more than that in non-MP infection patients (30.4% vs. 9.8%, P < 0.01), which indicated that patients with acute MP infection were more likely to have myocardial injury. While there were no significant differences in blood routine, blood electrolytes, blood glucose, as well as heart, liver and kidney function between the two groups. It was shown by chest imaging that the diffuse lesions (57.1% vs. 37.2%), mediastinal lymphadenopathy (60.7% vs. 37.8%) were less founded in the middle lobe of the right lung (12.5% vs. 32.9%), which were the main manifestations in patients with acute MP infection as compared with non-MP infection patients with statistical difference (all P < 0.01). There were no significant differences in the chest imaging performances of pulmonary ground glass shadow, lobar and segmental consolidation, patch shadow, a shadow, acinar nodules, grinding glass density nodules, the photic zone, hilar lymphadenopathy and pleural effusion occurrence between the two groups. Conclusion Adult CAP patients are easy to carry MP, myocardial damage is a common complication in acute MP infectious patients which are characteristic of image findings of diffuse lung disease, mediastinal lymphadenopathy and less founded in the middle lobe of the right lung.
