Objective To explore impact of nursing intervention on the adverse reaction of patient con-trol epidural analgesia (PCEA) after abdominal operation. Methods 258 patients underwent PCEA after ab-dominal operation were selected from 2006 to 2007. The clinical data of 126 patients without nursing interven-tion were analyzed as the control group admitted to our hospital from January to December, 2006 and compared with those of 132 patients receiving nursing intervention as the experimental group from January to December, 2007. The control group was managed by the anesthetists and nurses only conducted routine nursing instruction, while the experimental group was given systematic and normative nursing intervention besides routine nursing instructions, including psychological intervention, behavioral intervention, close observation, of discovery of ad-verse reaction in time and giving early disposal. The incidence of adverse reaction of PCEA of the two groups such as urinary retention, nausea and vomiting, abdominal distension, skin indentation, catheter shedding, skin itching, numbness of lower limbs, respiratory depression was observed. Results Compared with the control group,the incidence of adverse reactions of PCEA in the experimental group such as urinary retention,nansea and vomiting, abdominal distension,skin indentation,catheter shedding was significantly lower. Conclusions The implementation of nursing intervention can reduce the adverse reaction of PCEA after abdominal operation, alle-viate the suffering of patients, and promote functional recovery and the body rehabilitation.

ABSTRACT:In this study ,we aimed to analyze the transcription level of mitochondria gene Cytb in metacercariae ,larva‐30d ,larva‐60d ,adult ,and egg of Pagumogonimus skrjabini .The mRNA of metacercariae ,larva‐30d ,larva‐60d ,adult and egg of P .skrjabini were extracted with genomic extraction kit ,and transcripted reversely into cDNA .With 18SrDNA of Par‐agonimus westermani as an internal standard primer ,Cytb genes were amplified by real‐time PCR for establishing standard curves to evaluate the copy number of genes .Those quantitative analyses were reliable because the R value of standard curves was 0 .994 (>0 .98) ,and the melting curve showed a single peak .There were increasing trend of transcription of Cytb gene at metacercariae stage ,larva‐30d stage ,and larva‐60d stage .There were less transcription of Cytb gene at adult stage and no transcription at egg stage .There were differences about the transcriptional level of mitochondria Cytb gene at different stages of Pagumogonimus skrjabini ,and peaked at larva‐60d stage ,suggesting that Cytb gene may play a role in the development and migrating of larva .

OBJECTIVE: To investigate the changes of the markers of pulmonary vascular endothelial cells (PVECs) after acute lung injury (ALI) induced by bone marrow extract (BME) injection in rabbits. METHODS: Thirty-one rabbits were randomized into control (CG, n=10) and experimental groups (EG, n=21). The rabbits in EG were injected with homogeneous bone marrow extract (0.35 ml/kg, 2 ml/h) at a slow and continuous rate through the jugular vein to establish the model of ALI. At 6 h after the injection, the number of circulating endothelial cells (CECs) in the blood, contents of granule membrane protein-140 (GMP-140), angiotensin converting enzyme (ACE) and endothelin-1 (ET-1) in the plasma and the content of GMP-140 in the pulmonary tissue were determined at various time intervals. Then the animals were killed and routine pathological examination and electron microscopy were performed to observe the changes in the pulmonary tissue. RESULTS: The levels of plasma GMP-140, ACE, ET-1 and CECs were significantly increased in the early stage (0.5 h) and remained higher for 6 h. The marked increase of plasma GMP-140 (3.25 times) in the early stage was negatively correlated to PaO(2), but positively to other parameters. IHC-staining showed that the GMP-140 on the surface of PVECs became weak. CONCLUSIONS: BME injection at slow and continuous rate can establish an acceptable model of ALI. Determination of plasma GMP-140 might be an important measure for the early surveillance and the evaluation of prognosis of ALI in clinical management of serious traffic accidents.

This study sought to clarify the distribution of HMGN2 in HeLa cells. The recombinant eukaryotic expression vectors pcDNA3. 1-myc-his-HMGN2 and pEGFP-N1-HMGN2 were constructed, and then were transfected into HeLa cells. immunocytochemistry staining indicated that HMGN2 were present not only in HeLa nucleus but also in the cytoplasm. The presence of HMGN2 was also detected in the culture supernatant by ELISA with rabbit anti-serum against HMGN2 and mouse anti-His6 monoclonal antibodies. The confocal microscope observation showed the same subcellular localization as that of immunocytochemistry staining. There results suggested that HMGN2 could be present in the nucleus and cytoplasm of HeLa cell as well as in the extracellular environment.

OBJECTIVETo construct a lectin-like oxidized low-density lipoprotein receptor (LOX-1) RNA interference (RNAi) lentivirus and explore the role of LOX-1 in H(2)O(2)-induced apoptosis of rat myocardial cells.

METHODSLOX-1 shRNA sequence was synthesized and cloned into pLentiLox3.7 (pLL3.7) lentiviral vector to construct the lentiviral vector pLL3.7-LOX1. The lentiviral vectors (pLL3.7 and pLL3.7-LOX1) and the packaging vectors dR8.9 and VSVG were co-transfected into 293FT cells for packaging the lentivirus. H9C2 myocardial cells were infected by the lentiviruses to observe the inhibitory rate of LOX-1 on H(2)O(2)-induced apoptosis of H9C2 cells by RT-PCR, CCK-8, and Hochest33258 staining.

RESULTSDouble restriction enzyme digestion and DNA sequencing confirmed correct insertion of the sequence. Suppression of LOX-1 by the lentivirus attenuated H(2)O(2)-induced cell viability reduction and apoptosis in the myocardial cells (P<0.01).

CONCLUSIONLOX-1 activation may play an important role in H(2)O(2)-induced apoptosis of rat myocardial cells.

Human beta defensin 2 (HBD-2) may play an important role in human defense against infection. Its antimicrobial capacity has been fully documented in in vitro study. In order to evaluae its in vivo effects, we developed an HBD-2 transgenic mouse model. The HBD-2 minigene containing CMV promoter, full length of HBD-2 cDNA and BGH polyA tail was generated by PCR amplification and introduced into the fertilized oocytes of C57 X ICR hybridized mouse by microinjection, and offspring were produced. DNA was isolated from the tails of the mouse pups, and the HBD-2 minigene incorporation was analyzed by PCR using HBD-2 specific primers. The HBD-2 gene expression in the multi-tissues of transgenic mice was determined at mRNA level by RT-PCR and at peptide level by immunohistological staining with the use of HBD-2 monoclonal antibody. The results showed that among 17 F0 transgenic mice, HBD-2 positive signal was determined by PCR in 4 mice, suggesting that HBD-2 minigene has been incorporated into the offspring mice. Meanwhile, a widespread expression of HBD-2 mRNA and peptide was detected in the F1 transgenic mice's multi-tissues such as trachea, lung, intestine, esophagus, testis, spleen, skin, endothelium and brain.
