This paper describes the analysis of insitu polymerization of monomeric reactants (PMR) polyimide resin solution by reversed phase ion pair suppression chromatography. the mobile phase consists of acetonitrile and water. The methyl sulphonic acid was used as an ion-pair reagent in the mobile phase. The addition of sodium perchlorate was required to increase the ionic strength of the mobile phase. The information was obtained on monomeric isomer distribution of PMR polyimide resin solution and purity of prepared materials.

Objective To evaluate the cardiopulmonary allograft function and to analyze key factors for long-term survival of heart-lung transplantation in a patient survived more than 5 years. Methods On December 17th, 2003 at Zhongshan Hospital of Fudan University, a homologous heart-lung transplantation was performed on a female who diagnosed with cardiopulmonary failure secondary to congenital atrial septal defect with severe pulmonary hypertension. Heart-lung allograft was preserved with 1 000 mL UW solution and 4 000 mL HTK solution.Postoperative immunosuppressive therapies were managed with Zenapax, cyclosporine A (or tacrolimus), mycophenolate mofetil and corticosteroids. Cyclosporine A maintained with serum trough levels of 100-200 μg/L and tacrolimus with serum trough levels of 8-20 μg/L. Cardiopulmonary allograft functions were evaluated by echocardiogram, pulmonary function test and thoracic CT periodically. Results The patient survived operation and experienced normal daily life with NYHA cardiac function of class Ⅰ-Ⅱ during the follow-up of 5 years and 6 months. Echocardiogram showed left ventricular ejection fraction of 65% to 86%. Pulmonary function test exhibited with nearly normal oxygen exchange, meanwhile, small airway obstruction was detected from one year after operation and keeping stable from then on. Two episodes of severe pneumonia were complicated and treated with antibiotics and fhconazob, no severe acute allograft rejection episode was experienced. Conclusions Heart-lung transplantation proves to be a reliable therapy modality for terminal cardiopulmonary failure. Excellent donor organ preservation, accurate balance of the risk between acute allograft rejection and infection, and strict preventive measures against infection are key factors for long-term survival of heart-lung transplantation.

OBJECTIVE: To investigate a family with congenital dysfibrinogenemia, and analyze the risk of hemorrhage and thrombosis and blood transfusion strategies. METHODS: Prothrombin time (PT), activated partial thromboplastin time (APTT) and thrombin time (TT) of the proband and her family members were detected by automatic coagulometer, fibrinogen (Fg) activity and antigen were detected by Clauss method and PT algorithm respectively. Meanwhile, thromboelastometry was analyzed for proband and her family members. Then, peripheral blood samples of the proband and her family members were collected, and all exons of FGA, FGB and FGG and their flanks were amplified by PCR and sequenced to search for gene mutations. RESULTS: The proband had normal APTT and PT, slightly prolonged TT, reduced level of Fg activity (Clauss method). The Fg of the proband's aunt, son and daughter all decreased to varying degrees. The results of thromboelastogram indicated that Fg function of the proband and her family members (except her son) was basically normal. Gene analysis showed that there were 6233 G/A (p.AαArg35His) heterozygous mutations in exon 2 of FGA gene in the proband, her children and aunt. In addition, 2 polymorphic loci were found in the family, they were FGA gene g.9308A/G (p.AαThr331Ala) and FGB gene g.12628G/A (p.BβArg478Iys) polymorphism, respectively. The proband was injected with 10 units of cryoprecipitate 2 hours before delivery to prevent bleeding, and no obvious bleeding occurred during and after delivery. CONCLUSION Heterozygous mutation of 6233G/A (p.AαArg35His) of FGA gene is the biogenetic basis of the disease in this family with congenital dysfibrinogenemia.

Objective: To investigate the influence of long-time video operation on hemodynamics of the retrobulbar arteries in operators. Methods: From March to October, 2015, a total of 120 soldiers for office work engaged in video surveillance were enrolled as study group, and 155 fire fighters were enrolled as control group. The incidence of eye discomfort was compared between the two groups. Color Doppler ultrasound was used to measure and compare the peak systolic velocity (PSV) , end-diastolic velocity (EDV) , and resistance index (RI) of the central retinal artery (CRA) and the short posterior ciliary artery (SPCA) , and the correlation of video operation time with the hemodynamic parameters of the retrobulbar arteries was analyzed. Results: The study group had a significantly higher incidence rate of eye discomfort than the control group (P<0.05) . Compared with the control group, the study group had significant reductions in the PSV and EDV of the CRA and the SPCA and a significant increase in the RI of the CRA (P<0.05) . Video operation time was negatively correlated with the PSV and EDV of the CRA and the SPCA (r=-0.61, -0.54, -0.65, and-0.68, all P<0.05) and positively correlated with the RI of the CRA and the SPCA (r=0.56 and 0.63, P<0.05) . Conclusion Long-time video operation can increase the incidence of eye discomfort and lead to increased blood resistance of the CRA and the SPCA and reduced retinal perfusion.

Objective To investigate the expression of monocyte subsets and their chemokine,i.e.,monocyte chemoattractant protein (MCP-1) and fractalkine (FKN),in patients with acute coronary svndrome (ACS),and to analyze their correlation.Methods Patients with the syndrome of pectoralgia and to be inspected with coronary angiography (CAG) in our hospital from Sep.to Dec.,2016 were included.Patients' venous blood was collected on the operation day before operation,the level and proportion of monocyte (Mon) subsets,which was namely CD14 + CD16-Mon (Mon1),CD14+CD16 + Mon (Mon2) and CD14-CD16 + Mon (Mon3) according to the expression of cluster differentiation-14 (CD14) and CD16,were detected by flow cytometry (FCM).Patients' venous blood was collected on the operation day before operation and one day after operation,the concentrations of MCP-1 and FKN in plasma were measured by ELISA.We compared the expression levels of MCP-1-Mon1 and FKN-Mon3,and analyzed their relationship between each other respectively in different groups.Results Diagnosed according to the clinical symptoms,myocardial markers,electrocardiogram and CAG results,70 individuals were analyzed,including 30 patients with acute myocardial infarction (AMI group),25 patients with unstable angina pectoris (UAP group) and 15 patients with the chest pain symptoms and normal CAG results (control group).The percentage of Mon1 in the AMI group was higher than that in the other groups (P＜0.05);no difference was observed for Mon3 among the groups (P＞0.05).The Mon3/Mon1 ratio in the AMI group was lower than that in the control group (P＜0.05).Moreover,the levels of FKN and MCP-1 in the ACS group were greater than those in the control group.The level of red blood cell distribution width (RDW) was significantly increased in the AMI and UAP group than that in the control group (P＜0.05).There was a significant correlation between FKN and Mon3 (P＜0.05,R=0.650 2).Conclusions The monocyte subset of Mon1 and Mon3 increased in the early stage of ACS,with their chemokine (FKN and MCP-1) increasing at the same time.There is a significant correlation between FKN and Mon3,which indicates MCP-1-Mon1 and FKN-Mon3 may participate in the pathophysiological process of early ACS in patients.

Objective:To investigate the incidence, drug sensitivity and drug resistance characteristies, and theraputic effect of staphylococcal peritoneal dialysis-associated peritonitis (PDAP), aim to provide clinical evidences for standardizing treatment therapy of staphylococcal PDAP. Methods:Clinical data of PDAP patients admitted to the Second Hospital of Jilin University, the First Hospital of Jilin University-the Eastern Division, Jilin Central Hospital and Jilin First Automobile Work General Hospital during January 1, 2013 and December 31, 2019 were retrospectively collected. The results of etiology, drug sensitivity and drug resistance of staphylococcal PDAP patients were collected. According to the pathogenic bacteria, patients were divided into staphylococcus aureus group ( n=48) and coagulase-negative staphylococcus group ( n=232). According to the results of methicillin resistance, patients were divided into drug-resistant group ( n=71) and drug-sensitive group ( n=30). The prognosis of antibiotic therapy in each group were compared. Poisson regression was used to test the changing trend of the incidence of staphylococcal PDAP. The changes of drug sensitivity and drug resistance of staphylococcus were compared between 2013 and 2019 by linear trend χ2 test. Results:A total of 1 085 cases of PDAP occurred in 625 patients were screened, and 280 cases of staphylococcal PDAP were finally included. The incidences of staphylococcal PDAP, staphylococcus aureus PDAP and coagulase-negative staphylococcal PDAP were 0.063 times per patient year, 0.010 times per patient year and 0.053 times per patient year respectively. In addition, the incidence of PDAP caused by staphylococcus, staphylococcus aureus and coagulase-negative staphylococcus decreased year by year (all P<0.05). With the change of years, the sensitivity rate of staphylococcus to rifampicin increased, while the sensitivity rate of staphylococcus to moxifloxacin decreased (both P<0.05). The drug resistance rate of staphylococcus to levofloxacin increased ( P<0.05). The staphylococcus aureus group was more prone to refractory PDAP and catheter removal than that in coagulase-negative staphylococcus group, and the recurrence rate was higher than that in coagulase-negative staphylococcus group (all P<0.05). The proportion of vancomycin used during the whole course of antibiotic therapy in drug-resistant group was higher than that in drug-sensitive group ( P<0.05). Conclusions:The incidence of staphylococcal PDAP decreases year by year, and the drug sensitivity characteristics of staphylococcus also change. The therapeutic outcomes of staphylococcus aureus PDAP are worse than that of coagulase-negative staphylococcus.
