[Summary] The paper reported perioperative respiratory nursing experience of 31 patients with emphysema complicating pneumothorax treated with lung volume reduction surgery under video-assisted thoracoscopy .The thoracoscopic surgery was completed in 27 patients and conventional thoracotomy were required in 4 patients because of severe pleural cavity adhesions .No severe respiratory complications occurred in all the patients .We deemed that positive preoperative mental nursing , respiratory preparation and exercises, proper physical training , intraoperative prevention of hazardous inhalation , postoperative effective analgesia , and careful management of closed thoracic drainage are key points of perioperative nursing .

Objective To explore the expression of matrix metalloproteinase-11 (MMP-11) gene in gastric cancer cells and its correlation with transcription factor Sp1.Methods T In the present study,the expression of the MMP-11 was studied and the importance of Sp1 in the expression of the MMP-11 was proved with reverse transcription polymerase chain reaction (RT-PCR),differential PCR,Western-Blot,and DNA sequencing analysis in 10 kinds of the gastric cancer cell lines.Results MMP-11 cDNA was amplified with RT-PCR and differential PCR.In 34 cycle,the MMP-11/β-actin of SNU16,BGC823,MKN45,SGC7901,MGC803,SNU5 and PAMC82 were 3.32 ±0.12,2.22 ±0.11,1.41 ±0.12,1.35 ± 0.05,1.19 ± 0.05,0.97 ± 0.05,and 0.79 ± 0.05 (F =371.54,P ＜ 0.001).DNA sequencing analysis and BLAST showed the MMP11/β-actin of SNU16 DNA was 2 ～2.5 times as much as that of others.This result indicated that MMP-11 gene was amplified on the SNU16 DNA.Differential PCR and DNA sequencing analysis were carried out to amplify the MMP-11 gene in the SNU16 cell.Toward a better understanding of transcription of the MMP-1 1 gene,bioinformics technology was used to demonstrate the existence of two GC-boxes of the 5'-flanking region of MMP-11 DNA.Sp1 protein and MMP-11 protein were over-expressed in tumor cells and tended to have correlation with them (r =0.951,P ＜ 0.05).Conclusions The present results described the expressions of MMP-11 and Sp1 in gastric cancer cells.Moreover and clarified the correlation between MMP-11 and Sp1.It will establish the basic theory in order to confirm further whether Sp1 is a significant promoter of the 5'-flanking region of MMP-11 DNA.

Objective To explore the changes of CD4~+ cell and relevant cytokines from chronic hepatitis B patients and the significance was discussed. Methods The expression of CD4,CD8 and CD28 molecules on PBMC was detected with Flow Cytometry.The levels of IL-2,IFN-?,IL-4,IL-10 and IL-12 in serum were measured with ELISA,and the liver function test including serum ALT,SB,ALP and albumin was conducted. Results Three conditions of CD4~+ ratio from PBMC in 86 patients were observed,that showed lower,similar or higher comparing with normal controls.According to CD4~+T cell ratio,the patients were divided into 3 groups.In three groups,the changes of CD28 expression paralleled to that of CD4~+T cell ratio.Except IL-4,the level of cytokines related to viral clearance such as IL-2,IFN-?,IL-10 and IL-12 in patients was elevated compared with controls(P

Currently all military hospitals attach great importance to the management of state-owned assets.However,there still exist some problems,such as weak management consciousness,irregular assets disposing and loose connections between management and accounting.The author ventures some measures to strengthen management consciousness,organization establishment,accounting procedures and monitoring mechanism.

In recent decades, with the development of electrophysiological and neuroimaging techniques, the researchers found that spinal cord injury (SCI) not only caused pathological changes in the spinal cord, but also in the brain. This paper reviewed the influence of SCI on the structure and function of the brain in terms of brain neuron degeneration caused by SCI, the changes of neurotrophic factor in brain, and the side-effects of medicine.

The Hospital Survey on Patient Safety Culture (HSOPSC) questionnaire was used for appraisal in a newly-built general hospital for all the nursing staff, and they were provided with a six-month safety culture training according to appraisal results.The training has elevated the positive response rate of the nursing staff towards all dimensions of patient safety culture, proving that scientific and reasonable safety culture training is conducive to nurses' perception of patient safety culture.

Objective To explore the diagnostic value of CT hypotonic colonography in carcinoma of colon.Methods A total of 55 cases who were diagnosed as ileus,abdomen mass or suspected colonic carcinoma clinically were undergone CT hypotonic clolonography in six years recently,in our hospital.Of them,CT data of 35 cases identified by pathology were analysed retrospectively.Results CT diagnosis was corresponded to the pathologic results in 34 cases .Of them,33 cases were colonic adenocarcinoma(1 case with intussusception of ileum-colon type),one case was abdominal multiple metastatic adenocarcinoma.One case with cecal inflammation and granulation tissues hyperplasia was misdiagnosed for colonic carcinoma by CT.21 of 35 cases were undergone colongraphy,of them,15 cases were diagnosed as colonic carcinoma,1 case was normal,colonographic failure occurred in one case and 4 cases were false negative.Conclusion Hypotonic water perfusion CT scan in the cases permitted under clinical condition(patient with ileus should be perfused with 3% meglumine diatrizoate) can display clearly the primary focus,the position and range of ileus,surrounding organ.It is more excellent than conventional CT and X-ray examination.

Objective To explore the expression of matrix metalloproteinase-11 (MMP-11) gene in gastric cancer and its correlation with transcription factor Sp1.Methods The expressions of the MMP-11 and Sp1 in level of RNA and protein in 11 specimens from the gastric cancer patients s were detected by RT-PCR,differential PCR and Western-blot,respectively.Results Electrophoresis illustration showed MMP-11 mRNA expression had significant differences in eight pairs of gastric cancer tissues and normal tissues,including 7 pairs of over expressed in gastric cancer tissues and low or no expression in normal tissues,and 1 pair of low expression in cancer tissues but high in normal tissues.The relative molecular weight of Sp1 protein was mainly 95×103 in cancer tissue and 106×103 in normal tissues.Activated MMP-11 protein mainly was over expressed in gastric cancer tissues,and low or no expression in normal tissues,but degradable MMP-1 1 protein was not observed.The enzyme prototype of and activated type of MMP-11 protein were also associated with Sp1 protein.Conclusions The MMP-11 mRNA expression in gastric tissue is higher than that in the adjacent tissues.Sp1 protein and MMP-11 protein are expressed in gastric cancer,but are low or no expression in normal tissue.There is relationship between Spl and MMP-11.

Ski, as an evolutionary conserved protein, is widely involoved in the proliferation and differentiation of many kinds of cells in different species. Ski also plays an irreplaceable role in many physiological and pathological processes of nervous system, including em-bryonic nervous system development, central and peripheral nervous system diseases, and so on, which may be assiciated with the signal pathways of transforming growth factor-beta and another family member bone morphogenetic protein.

Objective To investigate the clinical value and safety of thoracoscopic lung biopsy in the diagnosis of diffuse parenchymal lung diseases. Methods 35 patients with diffuse parenchymal lung disease underwent thoraco-scopic lung biopsy were reviewed in order to obtain clinical and pathological data. Results 31 cases were diagnosed by pathology, and the total positive diagnostic rate was 88.6 % (31/35), 10 cases as usual interstitial pneumonial (UIP), 6 cases as Tuberculosis, 4 cases as alveolar cell carcinoma, 3 cases as nonspecific interstitial pneumonia (NSIP), 3 cases as crypto-genieorganizingpneumonia (COP), 2 cases as pulmonary alveolar proteinosis (PAP), 1 case as Wegener's granulomatosis (WG), 1 case as acute interstitial pneumonia (AIP), 1 case as lymphangioleiomyomatosis (LAM). 3 cases (8.6 %) were occurred with postoperative complications, 2 cases as pulmonary infection combined with respiratory failure, 1 case as idiopathic pulmonary fibrosis with acute exacerbation, and 2 cases (5.7 %) were complicated with death. Conclusions Thoracoscopic lung biopsy is a safe and effective method which helps final di-agnosis of diffuse parenchymal lung disease.
