Objective To discuss the relationships between regular pattern changes of plasma fibrinogen (Fib),D-dimer and fibrinogen degradation products (FDP) levels and the recent dissolution of thrombus in patients with pulmonary embolism (PE) in 14 days after treatment.Methods A prospective study was conducted.PE patients admitted to Departments of Respiratory Disease in 4 hospitals from January 2015 to March 2016 were enrolled and all of them were treated with thrombolysis and/or anticoagulation after admission.The computed tomographic pulmonary angiography (CTPA) was examined pre-treatment and 14 days post-treatment in PE patients.The pulmonary artery obstruction index (PAOI) was assessed according to the Mastora scoring method to estimate the thrombus load.The plasma Fib,D-dimer and FDP levels were measured before and on 1,2,3,5,7 and 14 days after treatment,and the relationships between the change regularities of these parameters and PAOI were also analyzed.Results A total of 42 PE patients were enrolled.The curve change of coagulation-fibrinolytic system parameters in 14 days after treatment showed that the Fib level was raised to its peak on the 3rd day after treatment and then decreased (g/L:4.24 ± 1.45 vs.3.83 ± 1.56),representing that its curve change was in accordance with the quadratic model (P =0.095).After treatment,the D-dimer and FDP levels were kept declining,they were reached the valley on 14th day [D-dimer (mg/L):1.58 ± 1.38vs.8.84 ± 6.35,FDP (mg/L):4.23 ± 3.63 vs.23.41 ± 16.54],and their curve changes were in accordance with the cubic model (F was 32.190 and 34.326,respectively both P =0.000).The PAOI variation before and 14 days after treatment [(18.77 ± 14.22)％] was not correlated with Fib variation [(1.20 ± 0.93) g/L,r =-0.194,P =0.219],but was positively correlated with D-dimer variation [(7.29 ± 7.10) mg/L] and FDP variation [(19.29 ± 18.67) mg/L,r was 0.556 and 0.460,respectively;P was 0.020 and 0.002,respectively].Conclusions The D-dimer and FDP levels are kept falling in PE patients after treatment,suggesting that the pulmonary artery embolus is being dissolved.

Objective:To investigate the effect of multiple-modality exercise on symptom clusters and nutritional status of nasopharyngeal carcinoma patients with radiotherapy.Methods:A total of 92 nasopharyngeal carcinoma patients who received radiotherapy in the Panzhihua Center hospital were randomly divided into research group and control group, each group contained 46 cases. The control group received routine nursing and the research group received 4-week multiple-modality exercise. The scores of M.D. Anderson symptom inventory-head & neck module (MDASI-H&N), patient-generated subjective global assessment (PG-SGA) and other biochemical nutrition index were compared before and after intervention between two groups.Results:After intervention, the scores of fatigue, poor appetite, dry mouth, mouth/throat mucus, dysgeusia were 3.77±1.30, 3.48±1.22, 3.81±1.48, 4.24±0.83, 4.94±1.63 in the research group and 4.36±1.09, 4.52±1.25, 4.39±1.24, 4.24±0.83, 6.03±2.00 in the control group, respectively. Those scores were significantly decreased in the research group compared to the control group ( t value was 1.996-3.993, P<0.05). After 4 weeks of intervention, the PG-SGA total socres, body mass index, prealbumin, hemoglobin were 2.78±0.60, (22.08±2.61) kg/m 2, (199.60±27.16) mg/L, (105.59±17.62) g/L, those indexes were 4.14±1.08, (20.63±2.63) kg/m 2, (193.42±25.57) mg/L, (102.77±18.57) g/L, the total scores of PG-SGA were significantly decreased in the research group compared to the control group ( t value was 7.356, P<0.01). Conclusions:Multiple-modality exercise can alleviate symptom burden and promote nutritional status of nasopharyngeal carcinoma patients with radiotherapy.
