[ABSTRACT]OBJECTIVETo explore the method on reconstruction of long and special tracheal defects which can mostly match with natural airway: pedicle rib cartilage with cilia endothelial wall.METHODS8 experimental model of rabbits were trained with cervical double belt blood supply fascia embedding and autologous costal cartilage and nasal septum mucos in the first period, then followed by transplantation in the second period. After the operation, we would assess the physiology, breathing and histopathology index of the rabbits, etc. After the animal experiment, we tried to apply the method to an appropriate clinical case.RESULTS8 cases of experimental rabbits dead after the second period operation with the average survival time of 21.9 days and caused by asphyxia. Histopathological results: rib cartilage and trachea ring up of cartilage cells and fibers have high similarity in histology; cartilage of all cases under the cultivation of the pedicle fascial package has not been absorbed; all cases' nasal septum mucosa in the body and blood supply to differentiation under fascia nutrition. Then we applied the method on a clinical case.CONCLUSIONTrachea ring rib cartilage had a higher similarity to the tracheal cartilage on the histology and biological characteristics that can be used as the preparation of artificial trachea shaping material or cell culture to tissue engineering materials. Package of rib cartilage pedicle fascial can provide adequate blood supply to make up for a free training rib cartilage defect to its absorption. Nasal septum mucosa of pressure in the body and blood supply of the fascia nutrition can simulate the trachea ciliated epithelium, which can play its biological characteristics similar to the inner wall of the trachea.

Objective To learn the publications and influencing factors of scientific papers from nursing staff in China.Methods 750 authors were chosen in a stratified random sampling for survey,and the questionnaires included a survey form on nursing research papers publications and one research ability self-rating scalce Results The nursing staff surveyed published 1-70 papers per person,averaging 8.83papers per person; on average 0.45 papers were published per person per year.Main factors for research outputs range from high to low as follows:age,academic titles,research ability,education background and research training,with the Beta values of 0.255,0.234,0.142,0.093,and 0.087 respectively.Conclusion Nursing administrators need to develop respective objectives for nursing staff of different age,academic titles,education background and research ability,and set up an effective incentive mechanism to ignite the enthusiasm of scientific research.

Objective To analyse the research motives and its influencing factors of nursing staff.Methods 1000 authors who wrote for “Nursing Research” were chosen with a random code sampling method and were surveyed with a questionnaire,which inquired about their research motivation and self-rated research ability scale.Results Nursing research motives include to summarise clinical experience66.2％ (524/793),to get promotion 55.4％ (420/793),to contribute to nursing profession 37.2％ (295/793),to report research achievements 35.6％ (282/793),and to meet the requirements of the institution17.5％ (139/793).Research motives were statistically different in terms of age,work expirence,educational background,professional title,attitude,research training,research ability,and work institution (P =0.013,0.037,0.048,0.002,0.024,0.008,0.005,0.009,0.004,P＜0.05).Conclusions To stimulate the enthusiasm for research in nursing staff,administrators need to pay great attention to higher education for nurses,enhance their research training,provide research platform,and to improve the incentive system.

Objective To explore the effects and molecular mechanisms of laser therapy on serum and colon tumor necrosis factor α (TNF-α),interleukin-6 (IL-6) and interleukin-10 (IL-10) in rats with oxazolone induced ulcerative colitis (UC).Methods Thirty adult male SD rats were randomly divided into four groups:a normal group ( n =6),a UC model group ( n =8 ),a 400 mW laser treatment group ( n =8 ) and a 200 mW laser treatment group ( n =8 ).Odified oxasolone sensitization was used to induce UC models in the rats.The AsAlGa semiconductor laser used in the treatment had a power of 200 mW or 400 mW.The therapy lasted for 10 days with daily 10 min sessions.The rats were sacrificed after treatment and enzyme-linked immunosorbent assay (ELISA) was used to measure IL- 6,IL- 10 and TNF-α in serum and ulcer tissues in all groups.Results Compared with the normal group,the weights of the UC model rats were significantly lower,and they had severe mucoid bloody stool.TNF-α and IL-6 levels in serum and colon tissues increased significantly and IL-10 decreased significantly,so the UC model was successfully established.After laser treatment,body weight gain and stool moderation in rats were observed.in the 400 mW group,and average TNF-α and IL-6 levels in both serum and colon tissue decreased significantly.IL-10 increased significantly,close to the level of the normal group.In the 200 mW group,serum TNF-α and IL-6 levels were significantly lower,and IL-6 in the colon tissue was reduced significantly.TNF-α did not lessen significantly,and serum and colon tissue IL-10 levels did not improve significantly compared with the model group.Conclusions 400 mW AsAlGa semiconductor laser irradiation can effectively regulate cytokines after oxaZolone induced UC in rats in two ways.It reduces pro-inflammatory cytokines and increases the level of anti-inflammatory cytokines.This may imply one of the underlying molecular mechanisms of low energy laser treatment of UC.

Objective To observe any therapeutic effect of laser irradiation on pathological inflammatory reactions in ulcerative colitis (UC) induced by oxazolone,and to investigate possible mechanisms.Methods Six rats were selected as a normal control group.Another 24 rats with UC induced by oxazolone were randomly assigned to a UC model group (n =8),a 400 mW laser group (161.3 mW/cm2,n =8),and a 200 mW laser group (80.6 mW/cm2,n =8).All the rats were fixed in custom-built devices.Those in the therapy groups were treated daily,10 min per time,for 10 days.After the end of the last irradiation session,disease activity indexes (DAIs)were observed.Rats from every group were sacrificed 24 h after the last irradiation in order to observe any pathological changes in colon tissue,the weight of fresh ulcerated tissues,and gross changes in morphology.Colon segments were stained with hematoxylin-eosin and histological lesion scoring was performed under a light microscope.Any changes in inflammatory edema in the colonic mucous membrane were observed before and after laser irradiation.Results The UC model was successfully established.Average body weight in the 400 mW laser group increased significantly more than in the UC model group,approaching that of the normal control group.DAI decreased significantly.The thickness of the epithelial mucous membrane,lamina propria and submucosa was basically restored.Histological lesion scores also improved significantly,and the weight of fresh ulcerative tissue was significantly lower.Mucous membrane ulcers,submucosa edema and inflammatory cell infiltration all were alleviated significantly,merely presenting a few inflamed cells and small amounts of periphlebitis.In the 200 mW laser group all these outcome measures improved significantly compared with the UC model group,but were not as good as in the 400 mW laser group,and the rats needed longer to recover.Conclusion Laser irradiation at 400 mW has advantages over 200 mW,and could significantly relieve the pathological inflammatory response in colonic tissue,decrease submucosa edema and ameliorate other symptoms of ulcerative colitis,at least in rats.

Objective To investigate the relationship between anti-Helicobacter pylori (Hp) antibodies and development of chronic urticaria (CU).Methods Fifty CU patients with positive 13C-urea breath test and anti-Hp antibodies,as well as 50 healthy human controls were recruited in this study.Serum samples were collected from all the subjects.The samples from the patients were subjected to tests for anti-high affinity IgE receptor (anti-FcεRI) and-IgE antibodies.Human mast cells (HMCs) were classified into several parts to be incubated with the sera of patients with CU,the sera of healthy controls with anti-IgE and-FcεRI antibodies respectively for 20 minutes.Those incubated with the sera of healthy controls without these antibodies served as the control.Subsequently,the levels of histamine released by HMCs were measured by enzyme-linked immunosorbent assay (ELISA).Results The sera of CU patients showed a stronger ability to activate HMCs to release histamine than those of healthy controls ((3.13 ± 0.93) μg/L vs (2.92 ± 0.75) μg/L,t =2.39,P ＜ 0.05).Anti-FcεRI antibodies were detected in 4 patients,and antiIgE antibodies in 3 patients.A significant increase was observed in the levels of histamine released by HMCs incubated with anti-FcεRI antibody-positive and anti-IgE antibody-positive patient-derived sera (t =4.82,6.34,respectively,both P ＜ 0.01),but not in those incubated with patient-derived sera only positive for anti-Hp antibodies (t =1.74,P ＞ 0.05) compared with those incubated with healthy control-derived sera.In comparison with the antibody-free healthy control-derived sera,those with anti-Hp IgG antibodies showed no significant effect on the release of histamines by HMCs (t =1.95,P ＞ 0.05),whereas those with anti-FcεRI antibodies and anti-IgE antibodies exhibited an obvious promoting effect (t =3.72,3.02,respectively,both P ＜ 0.01).Conclusions The anti-Hp antibodies appears to have no role in the pathogenesis of CU,but the presence of anti-FcεRI and anti-IgE antibodies may contribute to the initiation of CU in patients with Hp infection.

Objective To estimate the correlations between chronic idiopathic urticaria (CIU) development and interrelated autoantibodies,including anti-high affinity immunoglobulin E receptor (anti-FcεRI) antibody,anti-immunoglobulin E (anti-IgE) antibody,anti-Helicobacter pylori (HP) antibody and antithyroglobulin antibody (TGAb).Methods This study included 100 patients with CIU,100 patients with acute urticaria (AU) and 100 healthy controls.Autologous serum skin test (ASST) was performed and allergens were detected by fluorescence-based enzyme linked immunosorbent assay (ELISA) in each subject.Serum levels of total IgE,anti-FcεRI antibody,anti-IgE antibody,anti-HP antibody and TGAb were measured.Chi-square test,analysis of variance,and Wilcoxon rank sum test were conducted for statistical analysis.Results The positivity rate of ASST was 53％,12％ and 0 respectively in patients with CIU,patients with AU and healthy controls,respectively.Food or inhalant allergens were detected in 86％ of the patients with AU,but not detected in any of the patients with CIU or healthy controls.Patients with CIU showed significantly higher levels of anti-FcεRI antibody and anti-IgE antibody compared with patients with AU and healthy controls (all P ＜ 0.05).The serum IgE level in healthy controls was statistically lower than that in patients with AU (T =226.00,P ＜ 0.05),but higher than that in patients with CIU (T =190.00,P ＜ 0.05).ASST-positive patients with CIU had a higher level of serum anti-FcεRI antibody (T =101.73,P ＜ 0.05),but a similar level of serum anti-IgE antibody compared with ASST-negative patients with CIU (T =312.04,P ＞ 0.05).No significant differences were observed in the positivity rate of anti-HP antibody (29％,19％ and 23％,P ＞ 0.05) or TGAb (18％,15％ and 11％,P ＞ 0.05) between the patients with CIU,patients with AU and healthy controls.Both anti-HP antibody-positive patients and TGAb-positive patients with CIU showed a significantly higher positivity rate of anti-FcεRI antibody (all P ＜ 0.01),but a similar positivity rate of anti-IgE antibody compared with the patients with AU and healthy controls (all P ＞ 0.05).Conclusions Anti-FcεRI antibody and anti-IgE antibody are present in patients with CIU,and may play a certain role in the pathogenesis of CIU.
