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.

Objective To explore the effects of early intervention on brain injury in premature infants with neonate respiratory failure (NRF). Methods 151 premature infants in neonatal intensive care unit (NICU) who were diagnosed as NRF within 24 hours after birth in our hospital were studied. All of them accepted endotracheal intubation and mechanical ventilation, and were complicated with brain injury. According to their admission date and their parents' desire, these premature infants were divided into routine group (n=71) and intervention group (n=80). Both 2 groups received similar routine care, and the intervention group accepted touching, passive exercise and stimulation of hearing, vision and touch in addition. Active motor training and family intervention were also given to the intervention group after dis-charge. They were assessed with Neonatal Behavioral Neurological Assessment (NBNA) at the corrected age of 40 weeks, Infant Neurologi-cal International Battery (Infanib) at the corrected age of 3 and 6 months, mental development index (MDI) and psychomotor development index (PDI) at the corrected age of 6, 12 and 18 months, Gesell Development Schedules at the corrected age of 18 months. Results There was no significant difference in NBNA score between 2 groups at 40 weeks of gestational age (P>0.05). The percentage of normal ones with Infanib was higher in the intervention group than in the routine group at the age of 3 and 6 months (P<0.05). The MDI and PDI were signifi-cantly higher in the intervention group than in the routine group at the age of 6, 12 and 18 months (P<0.001). The scores of gross motor, fine motor, adaptation, language and social skills were significantly higher in the intervention group than in the routine group at the age of 18 months (P<0.001). The incidence of sequelae was lower in the intervention group (12.5%) than in the routine group (25.4%) (P<0.05). Con-clusion Early intervention can promote the intelligence and motor development, and improve the outcome of brain injury in the premature infants with NRF.

Objective To evaluate the clinical value of bedside echocardiography in full term infants in NICU.Methods The bedside echocardiography was performed for 313 full term infants,and then they were ana-lyzed.Results The main clinical characteristics of totally 313 cases of neonates were tachypnea,heart murmur and cyanosis.Patent foramen ovale and patent ductus arteriosus were common in the no cyanotic blood shunt,no cyanotic congenital heart disease(CHD)was mainly made of atrial septum defect(31 cases),followed by ventricular septal defect (20 cases).Cyanotic CHD was made of pulmonary atresia(6 cases),complete transposition of great artery (5 cases),tetralogy of fallot(5 cases),total anomalous pulmonary venous drainage(5 cases).Tricuspid regurgitation was common in abnormal blood flow,moderate to severe pulmonary hypertension was common for full term infants. Conclusion There were many abnormal echocardiography examination results,and atypical noise was common in neonatal CHD,routine examination of bedside echocardiography for full term infants in NICU was important for early detection of CHD and may help treatment timely to improve the prognosis.

Objective To investigate the method and result of repairing multi-fingers soft tissue defects using the dorsal metacarpal flaps with cutaneous branches as pedicle.Methods From February,2010 to January,2013,9 patients with multi-fingers tissue defects were treated with the 2nd,3rd,4th dorsal metacarpal flaps with cutaneous branches as pedicles.The area of flaps ranged from 1.2 cm × 2.5 cm to 2.5 cm × 5.0 cm.The donor sites were sutured with full thick skin graft.Results All flaps survived.After a followed-up of 8 months to 24 months(average 12 months),the texture and shape of the flaps were good and non-bloated.The flap sensibility as sessment were S3-S3+.The two-point discrimination testing were 10 to 13 mm (average 11.6 mm).The TAM score of range of motion was 60％ to 75％ of the healthy side.The skin graft of donor site were soft.Conclusion Procedure of dorsal metacarpal flaps with cutaneous branches as pedicles easy is a good method to repaire the soft tissue defects of muhi-fingers.

Objective To investigate the reliability of Berg Balance Scale (BBS) applied in patients with Parkinson's disease (PD). Methods 121 PD inpatients from March to December, 2011 were assessed with BBS by 2 raters, and the testing procedure was videoed. One of the raters assessed with BBS via video 4 weeks later. The intraclass correlation coefficient (ICC) and Kappa coefficient between raters and between tests were investigated. Results The ICC was 1.00 of the total score between raters and 0.99 between tests, while the Kappa co-efficient were 0.66 to 0.93 and 0.69 to 0.99 of the items. Conclusion BBS is reliable in interrater and test-retest as applied in PD patients.

Objective To evaluate the safety and efficacy of the endoscopic resection of large nonampullary duodenal adenomas.Methods Twenty cases with large nonampullary duodenal adenomas(≥ 1.0 cm) were referred for EMR.After submucosal injection of the mixture of glycerin fructose solution and methylene blue,either en bloc or piecemeal snare polypectomy was performed.All resected specimens were retrieved for pathologic study.Follow-up gastroscopy was performed in patients after EMR.Results Among 20 lesions,six were found located in the 1st part(30％),13 were in the 2nd part(65％),and one in the 3rd part(5％)of the duodenum.The mean diameter of the lesions was 1.9 ± 1.1 cm.Endoscopic ultrasonography (EUS) was performed in 12 patients,and all lesions were originated from the mucosa.EMR was performed successfully in 20 patients.The en bloc resection rate was 75％ (15/20),and the mean time for EMR was 33.8 ± 16.7 min.The perioperative complication rate was 20％ (4/20).Bleeding occurred within 24 hours after EMR in 4 cases.There were no perforations.The complete resection rate was 100％.Of these 20 adenomas,14 adenomas were tubulous and 6 was tubulovillous.During the follow-up period (2-39 months),1 patient showed recurrence within 6 months after EMR.Conclusion Endoscopic resection of large nonampullary duodenal adenomas is safe and effective treatment.
