Chinese Journal of Practical Nursing 2009;25(11):30-31
Objective To investigate influence of holistic nursing on psychological conditions and complications of elderly patients after thoracic surgery. Methods 98 old patients (over 70 years old) un-dergoing thoracic surgery were divided in to the intervention group and the control group with 49 cases in each group. Routine nursing and holisfic nursing were given to the two groups. Self-rating anxiety scale (SAS) and self- rating depression scale(SDS) were adopted to evaluated psychological status of all patients and complications were also measured. Results SAS and SDS score of the intervention group greatly de-creased 14 days after operation,comphcations such as incision infection, pulmonary infection, mild hypother mia and times of cough were also lower than that of the control group. Conclusions Holistic nursing care has pivotal significance on reducing psychological barrier, post-operative complications and ira-provement of quality of life in elderly patients after thoracic surgery.

Objective To investigate the clinical efficacy of acupuncture plus ashi point pricking bloodletting in treating acute gouty arthritis.Methods Seventy patients with acute gouty arthritis were randomly allocated to a treatment group of 38 cases and a control group of 32 cases. The treatment group received acupuncture plus ashi point pricking bloodletting and the control group, routine medication. Blood uric acid and C reaction protein contents were measured in the two groups before and after treatment. The clinical therapeutic effects were compared between the two groups.Results There were statistically significant differences in blood uric acid and C reaction protein contents after one and two courses of treatment compared with before treatment in the two groups (P<0.01). After two courses of treatment, there was a statistically significant difference in comparing C reaction protein contents between the two groups (P<0.05). The total efficacy rate was 84.2% in the treatment group and 81.3% in the control group; there was a statistically significant difference between the two groups (P<0.05).Conclusion Acupuncture plus ashi point pricking bloodletting is an effective way to treat acute gouty arthritis.

Objective To evaluate the effect of ulinastatin on γ-aminobutyric acid (GABA) signal pathway in mice with ventilator-induced lung injury (VILI).Methods Thirty-six male Wister mice were randomly divided into 3 groups using a random number table:control group (group C), ventilator-induced lung injury group (group VILI),and ventilator-induced lung injury+ ulinastatin group (group UTI),n =12 in each group.VILI was induced by 4 h mechanical ventilation with tidal volume 40 ml/kg in groups VILI and UTI.Ulinastatin 1×10 5 U/kg was injected intraperitoneally 1 h before ventilation in group UTI,while the equal volume of normal saline was given in groups C and VILI.The mice were then sacrificed,the left lung was lavaged,and broncho-alveolar lavage fluid (BALF)was collected for determination of concentrations of protein,tumor necrosis factor-α(TNF-α),interleukin-1β(IL-1β)and intercellular adhesion molecule-1 (ICAM-1).The lung tissues were re-moved for determination of the wet to dry lung weight (W/D)ratio,the mRNA expression level of IL-1β,TNF-αand ICAM-1.The pathological changes of the lungs were determined under light micro-scope and the lung injury scores were also determined.Immunohistochemistry and Western blot were used to detected the protein expression level of GAD and GABAA R.Results The W/D ratio (6.7 ± 2.4 vs.8.5±2.3)and lung scores [(6.9±2.3)scores vs.(1 1.8±2.7)scores]were significantly de-creased in group UTI than those in group VILI.The concentrations of IL-1β[(56±1 1)ng/L vs.(77 ±1 5)ng/L],TNF-α[(105±29)ng/L vs.(1 58±37)ng/L]and ICAM-1 [(205±46)ng/L vs.(293 ±61)ng/L]in BALF in group UTI were significantly decreased than those in group VILI.The mRNA ex-pression levels of IL-1β(1.81±0.26 vs.2.58±0.34),TNF-α(1.61±0.15 vs.2.94±0.27)and ICAM-1 (1.74±0.27 vs.2.79±0.31)were significantly decreased in group UTI than those in group VILI.The protein expression levels of GAD (0.44±0.08 vs.0.18 ±0.04)and GABAA R (0.30 ±0.09 vs.0.15 ± 0.04)were significantly increased in group UTI than those in group VILI.Conclusion Ulinastatin can at-tenuate VILI probably through activating GABA signaling pathway.

Objective To elucidate whether Ang Ⅱ indnces the proliferation of mesangial cells through ROS-EGFR-JNK-AP-1 signaling pathway. Methods The incorporation of 3H-thymidine (3H-TdR) and cell count were used to measure mesangial cell (MC) proliferation. ROS production was determined by DCFDA fluorescence. EGFR and JNK activation was assayed by Western blot. Results Ang Ⅱ significantly enhanced ROS production in mesangial cells, which was up-regulated by 2.26 folds of control group after incubation with Ang Ⅱ for 60 min. Ang Ⅱ induced EGFR phosphorylation in dose- and time-dependent manner, with the peak (3.96 folds increase) at 30 min. EGFR phosphorylation was significantly blocked by AT1R antagonist losartan, antioxidant NAC, and NADPH oxidase inhibitor apocynin and DPI. EGFR antagonist AG1478 significantly inhibited Ang Ⅱ-induced mcsangial cell proliferation. Losartan, NAC, apocynin, DPI, and AG1478 ahnost abolished Ang Ⅱ-induced JNK activation. Conclusions ROS-EGFR-JNK-AP-1 signaling pathway is involved in Ang Ⅱ-induced mesangial cell proliferation. Apocynin and AG 1478 may be used as new therapy.

Objective To investigate the role of oxidative stress-dependent Rasextracellular signal-regulated kinase (ERK1/2) signaling in aldosterone (ALDO)-induced mesangial cell proliferation. Methods The incorporation of 3H-thymidine (3H-TdR) and cell count were used as the measure of mesangial cell (MC) proliferation.Western blotting was used to detect the activation of Ki-RasA,c-Raf,MEK1/2,ERK1/2 and PI3K. Results Aldosterone significantly induced human mesangial cell proliferation,and anti-oxidant N-Acetylcysteine (NAC),catalase,and super oxide dismutase (SOD) significantly inhibited ALDO-induced mesangial cell proliferation (P<0.01,respectively).Stimulation by ALDO for 3 h,Ki-RasA,c-Raf,MEK1/2,and ERK1/2 activity increased by 4.05-, 3.62-, 4.52-, and 3.40-fold compared with control group (P <0.01,respectively).NAC almost completely blocked ALDO-induced Ki-RasA,c-Raf,MEK1/2,and ERK1/2 activation (P<0.01,respectively).Ki-RasA siRNA dose-dependently inhibited Ki-RasA expression, ALDO-induced Ki-RasA activation, and mesangial cell proliferation (P <0.01,respectively).c-Raf inhibitor GW5074 and MEK1/2 inhibitor PD98059 also reduced ALDO-induced mesangial cell proliferation by 65% respectvely (P<0.01).Ki-RasA siRNA had no effect on ALDO-induced PI3K phosphorylation.Combining LY294002 and PD98059 completely blocked ALDO-induced mesangial cell proliferation (P<0.01). Conclusions ALDO-induced Ki-RasA-c-Raf-MEK-ERK signaling activation is dependent on reactive oxygen species (ROS) production,which mediates ALDO-induced mesangial cell proliferation.Inhibition of both ERK1/2 and PI3K signaling simultaneously completely blocks ALDO-induced mesangial cell proliferation.
