Objective To observe the nursing effect of closed needle-free style injection connector in endoscopic nasobiliary drainage (ERCP). Methods From June 2013 to June 2014, 400 patients of the common bile duct stones underwent ERCP technique and placed nasobiliary were divided into two groups according to chronological. Between June 1st, 2013 and December 20th, 200 patients were set as control group, between December 21th, 2013 and June 30, 2014, 200 patients were set as experimental group. For the control group, the nasobiliary duct was directedly connected to the disposable drainage bag. For the experimental group, the nasobiliary duct was connected to closed needle-free style injection connector, and then to the drainage bag. The incidences of the detached connection, the fracture of the connection with the nasobiliary duct, bile leakage from the connection, and post-ERCP infection were compared between two groups. Results The incidence of bile leakage, crack pipes, separation and postoperative infection occurred at the junction nasobiliary rates in the experimental group were 0,0,0,2%(4/200), which were far lower than 35% (70/200),11% (22/200), 6% (12/200), 6%(12/200) of the control group. The difference was statistically significant (χ2=31.75~169.60, P < 0.01). Conclusions The application of closed needle-free style injection connector can effectively avoid the detachment and fracture of the connection, the occurrence of bile leakage, and post-ERCP infection. This will be helpful to decrease the burden of nursing care and increase patients′satisficationdegree.

Objective To discuss specific CT signs of primary trachea,bronchus mucoepidermoid carcinoma.Methods A retro-spective analysis was made on CT features,clinical manifestations and relevant pathology materials of 10 cases of trachea,bronchus mucoepidermoid carcinoma that had been proved by pathological examinations.Results (1)Sites:1 case was in the trachea,1 case in the bronchus,3 cases in lobar bronchus,5 cases in segmental bronchus and they were all central types.(2)Form and size:2 cases were lobular,7 cases were oval or round,1 case was irregular.The maximum diameters of the tumor were 10-39 mm (averagely 25 mm).(3)Edge:8 cases had smooth edge,2 cases had rough edge with infiltration of adjacent pulmonary parenchyma.(4)Densi-ty:6 cases with uneven density,3 cases with even density.The density of 4 cases were higher than that of chest wall muscle,4 cases were similar to chest wall muscle and 1 case lower than chest wall muscle.Calcification can be seen in 4 tumors.(5 )Enhancement features:9 cases underwent CT enhancement scanning,8 cases had mild enhancement and 1 case with light enhancement.(6)Pe-ripheral conditions:all cases showed trachea or bronchus stenosis and blocking,5 cases with obstructive pneumonia,2 cases with obstructive atelectasis,3 cases with far-end bronchus obstructive mucous embolism,1 case with obstructive emphysema,there was no evident swelling in mediastinum or hilar lymph nodes,1 case with multiple pulmonary bulla and pneumothorax in the left lung.

Objective The study consisted of two parts: in part Ⅰ the effects of propofol or/and procaine on CD18, CD62L expression and superoxide anion (SOA) release of phorbol 12-myristal 13-acetate(PMA) stimulated human neutrophils (PMNs) were studied in vitro; in part Ⅱ the effects of propofol or/and procaine on IL-6 and TNF-?production in endotoxin-stimulated human whole blood were studied. Methods PMNs were separated from the whole blood obtained from healthy 20-40yr old subjects. Part Ⅰ consisted of 9 groups: in group 1 (control) phosphate buffer solution was added to PMNs; in group 2 PMNs were stimulated by PMA 100mg?ml-1 ; in group 3-5 different concentrations of propofol (0.4, 4.0,40?g?ml-1) were added to PMA stimulated PMNs; in group 6-8 different concentrations of procaine (1.5,15,150?g?ml-1 ) were added to PMA stimulated PMNs; in group 9 propofol 2?g?ml-1 and procaine 8?g?ml-1 were added to PMA stimulated PMNs. Part II also consisted of 9 groups: in groupl whole blood was mixed with normal saline; in group2 lipopolysaccharide (LPS) l?g?ml-1 was added to whole blood; in group 3-5 different concentrations of propofol (0.4,4.0,40?g?ml-1) were added to LPS stimulated whole blood; in group 6-8 different concentrations of procaine (1.5, 15, 150?g?ml-1 ) were added to LPS stimulated whole blood; in group 9 propofol 2?g?ml-1 and procaine 8?g?ml-1 were added to LPS stimulated whole blood. CD18, CD62L expressions were measured by flow cytometry. SOA release was determined by cytochrome C reduction in the presence or absence of superoxide dismutase (SOD) . IL-6 and TNF-? production were measured by using radioimmunoassay. Results Propofol or/and procaine depressed CD18 up-regulation, CD62L shedding and SOA release of PMA-stimulated PMNs and propofol was more effective than procaine. Propofol enhanced but procaine inhibited the increased production of TNF-? and IL-6 in the LPS stimulated whole blood but when propofol and procaine were used in combination. The effectof procaine predominated. Conclusions Propofol or/and procaine can attenuate tissue damage induced by neutrophils by inhibiting the function of neutrophils.
