This paper summarizes the systematic management of artificial airway for 36 postoperative patients with laryngeal cancers. A full-time nurse is responsible for the systematic artificial airway management to implement respiratory care,endotracheal tube care,infection prevention and control,nutritional support and health education. As a result,the incidence of fever,frequent cough,and bloody sputum was 2.12%. Pharyngeal fistula and pulmonary infection occurred in one patient,respectively. All the patients recovered well after intensive care. It is suggested that systematic artificial airway management can effectively reduce complications,improve the quality of nursing and increase patient satisfaction.

Objective To silence the expression of CTGF by small interfering RNA technology,to observe the influence on fibroblast?like synovial cell apoptosis and several apoptosis?related genes,and to explore the mechanism of action of CTGF in rheumatoid arthritis synovial lesions. Methods Effective CTGF siRNA was screened through real?time PCR. The influence of CTGF siRNA on FLS apoptosis was detected with FITC?PI double staining by flow cytometry. bax,bcl?xl and survivin were detected using real?time PCR when CTGF mRNA has been silenced. Results Compared with other 2 groups of oligo and NC oligo,H1 oligo exhibited the strongest interfering action to CTGF(inhibition ratio>70%),so that it is selected as the effective target gene sequence for the following experiment. Apoptosis of FLS induced by serum deprivation was significantly decreased in the presence of exogenous CTGF. When expression of the CTGFgene was knocked down in FLS,FLS apoptosis was significantly increased,and expres?sion levels of survivin mRNA were decreased significantly(P<0.01). Conclusion FLS survival is positively regulated by CTGF,which may through the sustaining the expression of survivin.

Objective To research the relationship between the gene polymorphism of serum amyloid A protein(SAA)1 and coronary heart disease(CHD).Methods By using PCR-RFLP and sequencing,the gene polymorphism of SAA1 of 183 patients with coronary heart disease and 152 healthy controls were analyzed.Result In the both groups 3 alleles(1.1,1.3,1.5)and 6 genotypes(1.1/1.1,1.1/1.5,1.1/1.3,1.3/1.3,1.3/1.5 and 1.5/1.5)were found.The frequency of 1.5 allele in healthy controls group was notably higher than that in CHD group(P

Objective To design a checklist (NICU-PoHC) for postoperative handover in the NICU (Neurosurgery Intensive Care Unit) in case of information omissions or task errors during the handover process,thus to improve patient safety.Methods Team discussion and literature review was conducted to compose the preliminary version of the NICU-PoHC.Then two rounds of panel review were conducted using the Delphi methods to revise the preliminary checklist and to calculate its Content Validity Index (CVI).Results The authority coefficient of experts was 0.86.Twenty experts proposed 7 suggestions for revision.The NICU-PoHC was developed,and its CVI was 0.88.Conclusions Our study developed the NICU-PoHC,which can be used as an assistant tool guiding the postoperative handover,preventing information omissions and task errors,and thus improving patient safety.

Objective: To extract the polysaccharides of Curcuma zedoaria Rosc (PCZ) and study its bioactivities. Methods: The crude polysaccharides were extracted from herbal slice of Curcuma zedoaria Rosc with hot water ,and precipitated by ethanol and savage deproteinization and depigmentation with activated charcoal. The constituents were isolated by column chromatography and the total polysaccharides content was determined. Experiments of immune function,anti-oxidation and anti-tumor activity of KM mice and in viro were studied. Results: The content of total polysaccharides of Curcuma zedoaria Rosc was 33.12%. and the extraction rate was 1.938% . It could raise spleen cell proliferation and transformation rate of lymphocyte and SOD activity in blood of mice. A higher antitumor effect of the polysaccharides by injection was observed dose-dependently. Conclusion: PCZ could raise the immune and anti-oxidative activities and then had a higher antitumor effect.

OBJECTIVE:To investigate the effect of Changji’an capsules on abdominal pain and the molecular mechanism re-lated to calcitoningene-related peptide(CGRP)and corticosterone(CORT)in diarrhea-predominant irratable bowel syndrome(IBS-D)model rats. METHODS:After the rat models of IBS-D were established by the method of separation of breast mick combined with stimulation with acetic acid,the rats were randomly divided into model group(isometric normal saline),pinaverium bromide group(0.018 g/kg),and Changji’an capsules high,medium and low dose groups(2.812 g/kg,1.406 g/kg and 0.703 g/kg),and another SD rats were included in the normal control group(isometric normal saline). The drugs were given to the rats once a day for consecutive 14 d,ig. Injection of normal saline method was adopted to determine the rat’s sensibility to abdominal pain. The en-zyme-linked immunosorbent assay(ELISA)was adopted to determine the content of CORT in the serum of the rats. Subjected to re-verse transcription polymerse chain reaction(RT-PCR)was adopted to determine the expression of CGRP mRNA in the hypothala-mus and colon tissues of the rats. RESULTS:Compared with normal control group,threshold values of arching the back and stick-ing out the abdomen were decreased,the content of CORT in serum and expression of CGRP mRNA in the hypothalamus and co-lon tissues in model group were increased,with significant difference(P<0.01). Compared with model group,threshold values of arching the back and sticking out the abdomen were increased,the content of CORT in serum and expression of CGRP mRNA in the hypothalamus and colon tissues in pinaverium bromide group and Changji’an capsules high and medium dose groups were de-creased;the threshold value of arching the back in Changji’an capsules low dose group were increased,with significant difference (P<0.01 or P<0.05). CONCLUSIONS:Changji’an capsules can improve the abdominal pain in rats with IBS-D by a mechanism that may be related to the decrease in the expression of CGRP mRNA in the hypothalamus and colon tissues and the reduc-tion of the content of CORT in serum.
