Aim To study the effect of two racemic ketamine, S(+)-ketamine and R(-)-ketamine on stimulus-induced superoxide generation and intracellular calcium in vitro. Methods The stimulus-induced superoxide generation in human neutrophils was determined by using method of cytochrome C reduction. The intracellular calcium in human neutrophils was measured by chemiluminescence with Fura-2 loading. The phosphorylation of p47phox of NADPH oxidase in neutrophils was detected by Western blotting. Results S(+)-Ket and R(-)-Ket inhibited fMLP-induced superoxide generation in neutrophils in a concentration-dependent manner. In the case of PMA, S(+)-Ket inhibited PMA-induced superoxide generation and elevation of intracellular calcium of neutrophils in a concentration-dependent manner, whereas R(-)-Ket slightly increased PMA-induced superoxide generation and elevation of intracellular calcium of neutrophils. On the other hand S(+)-Ket inhibited the phosphorytion of p47phox of NADPH oxidase subunit,which R(-)-Ket was increased. EGTA can abolished the inhibition of S(+)-Ket on PMA-induced phosphorytion of p47phox.Conclusion S(+)-Ket inhibits the phosphorylation of p47phox of NADPH oxidase subunit and the superoxide generation in human neutrophils via PKC-calcium signal pathway.

Alginate is natural polysaccharide carbohydrate extracted from sea tangle, and alginate dressing is soft non-textile fiber refined from seaweed. It contains 85% natural alginate fiber and 15% sodium tvIose. It can absorb effusion, form gelate, and exchange Na~+/Ca~(2+) with effusion. Alginate dressing has been widely used in bedsore treatment, anal fistula nursing, stoma nursing, and diabetic foot nursing. Compared with traditional dressing, infection rate of alginate dressing is lower due to good impermeability, promotion of regional vessel proliferation and blood supply, as well as moist and slightly acidic environment which benefits neutrophil function enhances disinfection.

Objective To explore the effect of continuous nursing based on WeChat public platform on the patients with high risk of pressure ulcers. Methods Selecting 165 pairs of high-risk patients and their caregivers from the emergency department of pressure ulcers in the General Hospital of Chinese People′s Armed Police Forces, and they were divided into control group and experimental group by paired random method. There were 83 pairs in control group, and 82 pairs in experimental group. The control group gave oral education according to the traditional model, and adopted the way of telephone follow-up for continuous nursing. While the experimental group let patients and their family members follow the Wechat public account that specially developed on Wechat platform and get continuous nursing in new models to come true networking health education and communicate with patients and their family members by multi-dimensional nurse. After 3 months intervening, compared patients′quality of life, the care behavior of caregivers and acquisition of knowledge of pressure scores, the incidence of pressure ulcers, degree of satisfaction of high-risk patients and caregivers between the two groups. Results The psychological function score, social function score and quality of life score was respectively ( 67.61 ± 1.67), (58.60 ± 1.52), (50.41 ± 2.70) points in experimental group, and (63.21 ± 1.30), (53.23 ± 1.92), (45.83 ± 2.59) points in control group, the comparative difference of the two groups was statistically significant( t=-4.638,-4.930,-2.749, P<0.05). There was no significant difference in the material life and body function score between two groups(P>0.05). The care behavior of caregivers score and pressure sores knowledge score was respectively (50.84 ± 1.92), (27.83 ± 1.48) points in experimental group, and (46.43 ± 2.40), (19.28 ± 1.31) points in control group, the comparative difference of the two groups was statistically significant (t=-3.192,-9.738, P<0.05 or 0.01). The incidence of pressure ulcers was 15.9%(13/82) in experimental group, significantly lower than that in control group (50.6%, 42/83), two groups was statistically significant (χ2=22.413, P<0.01). The satisfying degree and scores of patients or caregivers for follow-up form, nursing service attitude, follow-up content and the total score was respectively (24.83 ± 3.11), (24.10 ± 2.55), (25.03 ± 2.12), (76.23 ± 2.17) points in experimental group, and (18.34 ± 1.41), (17.41 ± 1.34), (19.85 ± 1.92), (63.25 ± 3.03) points in control group, the comparative difference between two groups had statistical significance (t=-7.797--4.061, all P<0.01). Conclusions Utilizing Wechat public platform continuity of care for patients at high risk of pressure ulcers can improve the patients quality of life, reduce the incidence of pressure ulcers, improve the efficient communication of nurses and patients, and enhance the degree of satisfaction of the patients. This method is convenient, shortcut, economic, practical and worthy for clinical use and promotion .

Objective To clone the full length staphylococcal protein A(SPA) gene from Staphylococcus aureus (ATCC6538), and subsequently study the gene structure and antibody binding ability.Methods The full length and the functional region of the SPA gene were cloned into pHisSUMO vector respectively, and expressed in E. coli. The full length and the functional fragment of the SPA protein were detected for antibody binding ability and stability. The functional fragment of the SPA protein fused with SUMO was coupled to the CNBr-activated agarose for antibody purification from rabbit serum. Results A variant of the full length SPA gene was cloned, which has been submitted to GenBank (the accession number is EU695225). Two fusion proteins had the same antibody binding ability as the untagged SPA protein. However, the formers was more stable than the latter at the tested conditions. SUMO-SPA conjugated-agarose kept high efficiency for antibody binding. Conclusion To our knowledge, the full length SPA gene of S.aureus(ATCC6538) is a novel variant. The SUMO tag can improve the stability of the functional region of the SPA protein without damaging the antibody binding ability. This fusion protein has been used for antibody purification successfully.

Objective To explore the feasibility and evaluate its efficacy of transnasal marsupialization of maxillary cyst under nasal endoscope. Methods 15 cases of maxillary cyst were treated by endoscopic marsupialization in nasal. According to the situation of maxillary cysts, the fenestration of bottom nasal was opened in 6 cases, the fenestration of inferior nasal meatus was opened in 7 cases and inferior nasaI meatus was opened through the prelacrimal duct recess in 2 cases under the nasal endoscope. With partial removal of the cyst wall, the cyst and maxillary sinus was fused into a cavity if necessary. This ensured nasal drainage through the cyst cavity and nasal cavity or maxillary sinus. Results The operations of the 15 patients were success without complications. All patients were followed up for 6 to 24 months after operation. Operation cavity to complete epithelization in 2 to 3 months, the cyst cavity drained well with no recurrence. Conclusion Endoscopic marsupialization in nasal is a feasible alternative for management maxillary cyst. It makes the procedure simple, less traumatic, quick recovery, definite curative effect and low recurrence rate.
