Objective To explore the clinical effect of non-invasive positive pressure ventilation(NPPV)for treatment of acute left heart failure after mitral valve replacement. Methods Sixty patients with acute left heart failure after mitral valve replacement in Xinxiang Central Hospital from April 2009 to August 2017 were selected. The patients were divided into control group and NPPV group,with 30 patients in each group. The patients in the control group were treated with double oxygen ab-sorption (mask and nasal catheter),strong heart,diuresis and dilated blood vessels. Based on the treatment of control group, the patients in NPPV group were treated with NPPV therapy. The plasma N-terminal pro-B-type natriuretic peptide(NT-proB-NP)level of patients in the two groups was monitored by rapid determination of immunofluorescence before treatment and 6,24 hours after treatment. The respiratory frequency,blood oxygen saturation,heart rate and oxygen partial pressure monitoring of patients in the two groups was monitored before treatment and 2,6 and 24 hours after treatment. Results The total effective rate of patients in the control group and NPPV group was 92. 4%(26 / 28)and 96. 6%(28 / 29)respectively;there was no sig-nificant difference in the total effective rate between the two groups(χ2 = 1. 25,P > 0. 05). There was no significant difference in the plasma NT-proBNP level between the two groups before treatment (P > 0. 05);the level of NT-proBNP at 6,24 h after treatment was significantly lower than that before treatment in the two groups (P < 0. 05);the level of NT-proBNP of patients in the NPPV group was significantly lower than that in the control group at 6,24 h after treatment (P < 0. 05). There was no significant difference in the respiratory frequency,blood oxygen saturation,heart rate and oxygen partial pressure between the two groups before treatment(P > 0. 05). Compared with before treatment,the respiratory frequency and heart rate of patients were decreased and the blood oxygen saturation,oxygen partial pressure were increased at 2,6,24 h after treatment in the two groups (P < 0. 05). There was no significant difference in the oxygen partial pressure between the two groups at 2 h after treat-ment(P > 0. 05);the oxygen partial pressure of patients in the NPPV group was significantly higher than that in the control group at 6,24 h after treatment(P < 0. 05);there was no significant difference in the respiratory frequency,blood oxygen satu-ration and heart rate between the two groups at each time piont after treatment(P > 0. 05). Conclusion NPPV is an effective treatment for acute left heart failure after mitral valve replacement.

OBJECTIVETo explore the feasibility of transferring fusion gene of dihydrofolate reductase (DHFR) gene and cytidine deaminase (CD) gene into mouse bone marrow cells in order to observe the drug resistance of high dose methotrexate (MTX) and cytosine arabinoside (Ara-C) in the bone marrow cells and to improve the tolerance of myelosuppression following combination chemotherapy.
METHODSHuman double-mutant dihydrofolate reductase-cytidine deaminase fusion gene was transferred into two mice bone marrow cells by retroviral vector. Resistant colony-forming unit granulocyte-macrophage (CFU-GM) assays were performed in mouse bone marrow cells by retroviral infection and after treatment by drugs (Ara-C, MTX, and Ara-C + MTX). DNA was extracted from mouse bone marrow cells. The expression of drug resistant genes in mouse bone marrow cells after transferring by retroviral vector was checked by polymerase chain reaction (PCR).
RESULTSBone marrow cells after coculture with the retroviral producer cells transduced with the genes (SFG-F/S-CD) showed the drug resistance colonies yield (Colony formation after exposure to Ara-C, MTX and Ara-C + MTX were 56%, 22% and 14%, respectively) and the increase in drug resistant to both MTX and Ara-C (P < 0.005). Expression of DHFR and CD gene in extracted DNA of transfected mice were demonstrated by PCR.
CONCLUSIONSDouble drug resistant gene can not only integrate and co-express in mice bone marrow cells but also increase the drug resistance to MTX and Ara-C.

BACKGROUNDBacterial pneumonia in the recipients of liver transplantation (LTX) is a common postoperative complication influencing the prognosis greatly. In this article, the diagnosis and treatment of bacterial pneumonia in 33 LTX recipients are reported.
METHODSFrom February 1999 to January 2003, a total of 103 patients underwent allogeneic LTX at our center; afterwards, a retrospective analysis was made on their postoperative clinical manifestations, including symptoms (expectoration, panting and fever), sign (rale), results of laboratory examinations (white blood cell count and sputum culture of tracheal secretions or pleural fluid culture), and chest X-ray films. The following data of the pneumonia and non-pneumonia groups were collected, and the rank sum test (SPSS 11.0, Wilcoxon's method) was used to analyze the duration of postoperative respirator utilization and the volume of pleural effusion through pleurocentesis or pleural drainage.
RESULTSIn the 103 patients, 33 experienced 53 episodes of bacterial pneumonia during their hospital stay after transplantation, 14 of them (42.42%) had more than three manifestations of the seven mentioned above. The pathogens causing bacterial pneumonia included Pseudomonas aeruginosa (17.48%), Klebsiella pneumoniae (15.53%), Acinetobacter baumannii (10.68%), and Staphylococcus aureus (7.77%). Amilkacin, tienam, ciprofloxacin, vancomycin, etc. were the antibiotics of choice against those bacteria. Acute rejection occurred during the treatment of bacterial pneumonia in 16 patients, and 5 of them died. Wilcoxon's rank sum test of the data indicated that the pneumonia group had longer duration of postoperative ventilator treatment and larger volume of pleural effusion than the non-pneumonia group (P < 0.05).
CONCLUSIONSThe clinical manifestations of pneumonia after LTX might be atypical, and special attention should be paid to the respiratory symptoms and signs within 2 months after LTX. Whenever the diagnosis of bacterial pneumonia is confirmed, consideration should be given to reasonable use of antibiotics and regulation of immunity in addition to other routine therapies.

OBJECTIVETo investigate the biological characteristics of dermal fibroblasts of the diabetic rats with deep partial thickness scald, and to explore its relationship with delayed wound healing due to diabetes.
METHODSSprague-Dawley rats weighing 250 g were randomly divided into control (NM, n=40) and STZ-induced diabetic (DM, n=50) groups, and then deep partial thickness scald involving 10% TBSA were reproduced in the two groups. Skin samples were harvested from the wounds on 0, 3, 7, 14 and 21 post scald day (PSD) for the determination of certain histological characteristics.
RESULTSThe thickness of dermis layer in DM group before injury was obviously thinner than that in NM group (P < 0.01). There was an infiltration of a large amount of chronic inflammatory cells and increased content of cutaneous glucose in the dermal tissue in DM group (2.77 mg/g) compared with 0.85 mg/g in NM group, (P < 0.01). An accumulation of advanced glycation end products (AGEs) was found in the dermal tissue in DM group. After the scalding, the percentage of fibroblasts in S phase and hydroxyproline synthesis in DM group was evidently lower than those in NM group. But the apoptosis rate of fibroblasts was much higher in DM group than that in NM group (P < 0.05 or 0.01).
CONCLUSIONIt is found that the high contents of glucose and AGEs in diabetic skin exert untoward effects on biological characteristics of dermal fibroblast, probably constituting one of the underlying mechanisms of delay wound healing of scald in diabetic rats.
