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 investigate the effects of therapeutic exercise(cage running)on the expression of Bel-2 and Bax in neuronal cells after cerebral hemorrhage(ICH)in rats. Methods A total of 120 male Sprague-Dawley rats weighing 270 to 300 g were divided into a trial group(ICH and exercise group,n=40),a control group (ICH only,n=40)and a sham-operated group(sham ICH operation and no exercise,n=40).The brains were removed at 7,14,21 and 28 days after ICH.The activation of Bcl-2 and Bax WaS measured by immunohistochemical techniques,Western blotting and reverse transcriptase polymerase chain reaction(RT-PCR).Results (1)Bel-2-positive and Bax-positive cells appeared in tissues surrounding the hematoma in the cortex.The number of Bcl-2-posotive and Bax-positive cells was nearly zero in the sham-operated group.In the trim group.the number of Bcl-2-positive cells increased significantly from the 21 st to the 28th day.Bax.positive cells decreased from the 7th to the 28th day after ICH when compared with the control group and the sham-operated group.(2)The expression of Bcl-2mRNA and Bax-mRNA as shown by Western blotting and RT-PCR methods was synchronous with the immunohistochemistry results.The peaks of Bcl-2mRNA and BaxmRNA expression were a little earlier than those of Bcl-2 and Bax proteins. Conclusion Exercise can mitigate neuronal cell apoptosis by upregulating the expression of Bcl-2 and Bcl-2 mRNA,and downregulating the expression of Bax and Bax mRNA.

Objective To evaluate the effect of integrated service platform of extensional care based on the combined internet and extensional care model in the orthopedics nurse care. Methods Two hundred and eighty six hospitalized patients in the orthopedic department were randomly divided into two groups including experimental group (144 cases) and control group (142 cases) according to the random number table method. Patients in the control group received extensional care by traditional telephone follow-up, patients in the experimental group received extensional care by using the integrated service platform combing internet and extensional care. All the patients were evaluated using the self-made extensional care satisfaction questionnaire and Short Form 36 Questionnaire. Results The extensional care satisfaction scores of experimental group using internet plus extended care mode were respectively ( 74.4 ± 5.3) points and (76.2 ± 8.1) points at the time points of 3 months and 6 months after discharge from hospital;The extensional care satisfaction scores of control group were respectively (69.4±9.9) points and (70.1±12.2) points at the time points of 3 months and 6 months after discharge from hospital;The two groups had statistically comparative difference (t=7.40, 6.37, P<0.01). There was a statistically significant improvement of extensional care satisfaction and physical function score and role-physical score and social function score in the experimental group compared with the control group both at the time points of 3 months and 6 months after discharge from hospital. There was a statistically significant improvement of vitality score and role-emotion score in the experimental group compared with the control group both at the time points of 1 month and 3 months after discharge from hospital (t=2.366-8.211, P<0.05). Conclusions The effect of integrated service platform of extensional care based on the combined internet and extensional care model is better than traditional telephone follow-up, patients′satisfaction is higher. This new mode of service platform could greatly deepen the connotation of quality nursing, intensify the effect of extensional care, and reduce the working strength of nurse who did extensional care as while.
