Objective To study on the effect of nttrsing intervention on coping with fatigue in patients with cervical spine fracture and high paraplegia.Methods 46 patients who suffered cervical spine fracture with paraplegia were divided into the control group and the intervention group with 23 patients in each group randomly.The control group received routine care in general,while the intervention group was given additional systematic nursing intervention by full-time nurses.The brief fatigue inventory(FSI),as fatigue assessment tools,was used to assess the fatigue of patients in the two groups before invention and 20 days after invention respectively.Results As a result,we found that the difference of fatigue between the two groups had no prominent significance before intervention,but after invention the difference had prominent significance.Conclusions The nursing intervention is very important for patients with cervical spine fracture and paraplegia and has significant advantages to alleviate or eliminate patients' fatigue and improve their quality of life.

Objective To evaluate the effect of cardamonin on acute lung injury induced by hemorrhagic shock and resuscitation (HSR) in rats.Methods Thirty-two male Sprague-Dawley rats,aged 18-24 weeks,weighing 200-250 g,were divided into 4 groups (n =8 each) using a random number table:sham operation group (group Sham);group HSR;cardamonin group (group CA);cardamonin + adenosina A2A receptor antagonist ZM241385 group (group CZM).Bilateral common carotid arteries were only cannulated in group Sham.The left common carotid artery was cannulated for blood-letting until mean arterial pressure was reduced to 35-45 mmHg and maintained at this level for 30 min,and the animals were then resuscitated by infusion of shed blood and normal saline two-fold volume of shed blood to establish HSR model in HSR,CA and CZM groups.ZM241385 5 mg/kg was injected intraperitoneally at 30 min before blood-letting in group CZM,and cardamonin 75 mg/kg was injected intraperitoneally immediately after the beginning of resuscitation in CA and CZM groups.The rats were sacrificed at 2 h after completion of resuscitation,bronchoalveolar lavage fluid (BALF) was collected for determination of neutrophil count,and lungs were removed for microscopic examination of the pathological changes and for determination of wet/dry lung weight ratio (W/D ratio),contents of tumor necrosis factor-alpha (TNF-ct),interleukin-1 (IL-1β) and IL-6 (by enzyme-linked immunosorbent assay) and expression of adenosine A2A receptors in lung tissues (by Western blot).Results Compared with group Sham,the neutrophil count in BALF,W/D ratio and contents of TNF-α,IL-1β and IL-6 were significantly increased,the expression of adenosine A2A receptors was significantly down-regulated in group HSR,and the neutrophil count in BALF and contents of TNF-α and IL-6 were significantly increased (P＜0.05),and no significant changes were found in W/D ratio,content of IL-1β,and expression of adenosine A2A receptors in group CA (P＞0.05).Compared with group HSR,the neutrophil count in BALF,W/D ratio and contents of TNF-α,IL-1β and IL-6 were significantly decreased,the expression of adenosine A2A receptors was significantly up-regulated (P＜0.05),and the pathological changes were significantly attenuated in group CA,and no significant changes were found in the parameters mentioned above in group CZM (P＞0.05).Compared with group CA,the neutrophil count in BALF,W/D ratio and contents of TNF-α,IL-1β and IL-6 were significantly increased,the expression of adenosine A2A receptors was significantly down-regulated (P＜0.05),and the pathological changes were aggravated in group CZM.Conclusion Cardamonin can attenuate acute lung injury induced by HSR in rats,and activated adenosine A2A receptors and inhibited inflammatory responses are involved in the mechanism.

Objective To analyze the clinicopathologic data and operative parameters of 209 elderly co-lon cancer patients treated by radical resection between January 2002 and December 2011 ,and to investigate the factors related to recurrence and metastasis after colon cancer radical resection in elderly patients .Methods We used univariate and multivariate analysis of Cox regression ,including 14 variables:age,gender,disease duration, hospitalization duration,surgeon experience,operation duration,laparoscopicsurgery,tumor location,tumor size, gross morphology ,differentiate degree ,depth of bowel wall invasion ,lymph node involvement and obstruction .The survival curve was obtained by Kaplan -Meier method.Results Univariate analysis showed that tumor size (RR=2.658,P<0.0001),gross morphology(Infiltrating type,RR=3.407,P=0.0054),degree of differentiation (RR=0.32,P<0.0001) were associated with tumor relapse and metastasis .Multivariate analysis showed that gender(RR=0.585,P=0.0359),tumor size(RR=2.364,P<0.0001),degree of differentiation (Infiltrating type,RR=0.246,P=0.0437),gross morphology(RR=0.31,P<0.0001)were the significant factors.Conclu-sion Gender,tumor size,degree of differentiation,gross morphology were the independent factors of recurrence and metastasis of colon cancer after radical resection in elderly patients .Targeted follow -up for high -risk groups will improve patients′life quality and prolong their survival time .

Objective To investigate the ultrasonic image characteristics of Zenker diverticulum(ZD).Methods The ultrasonographic features were summarized using the analysis confirmed by surgery pathology or X-ray imaging of the ZD in six eases.Results The diverticulum of Zenker located behind the thyroid gland in all the six cases,with five cases to the left and one to the right.The internal hyperechoic foci caused by air was found for all the six cases.The diverticulum wall appeared to be semicircular,narrow-band and acoustic halo low echo with an average thinckness of 0.53 mm.The Doppler sonogram of the six diverticulums showed no vascular signal.Conclusions The ZD had several unique characterisitics for identification by ultrasonic diagnosis,which included hyperechoic foci caused by air,internal changes of echo after drinking water and the special layered structure of the five-layer ZD wall.

Objective To investigate the role of transient receptor potential melastatin 7 (TR PM7) in the protective role of sevoflurane preconditioning against hippocampal neuron injury caused by oxygen glucose deprivation (OGD).Methods Hippocampal neurons were harvested from postnatal day 1 SD rats,and randomly divided into 5 groups:control group (group C),sevoflurane group (group Sev),oxygen-glucose deprivation group (group OGD),sevoflurane+ OGD group (group SD) and sevoflurane+OGD+bradykinin group (group B).To build up the model of OGD,the neurons were cultured in a deoxygenated glucose-free medium and exposed to 95％ N2 and 5％％ CO2 in an anaerobic chamber equilibrated at 37℃ for 1.5 h,followed by replacement with glucose containing medium and return to a standard incubator for additional 24 h.The neurons in group C received no treatment.Group OGD was preconditioned with 2 ％ sevoflurane for 1 h.The neurons in group OGD were subjected to OGD.Group SD was preconditioned with 2％ sevoflurane for 1 h,followed by OGD at 24 h after the sevoflurane exposure.The neurons in group B was incubated in a medium supplemented with 200 μmol/L bradykinin (the selective agonist of TRPM7),followed sequen tially by the preconditioning of 2％ sevoflurane for 1 h and then OGD challenge.Twenty-four hours after re-oxygenation,The relative neuronal cell viability was determined by MTT assay,the neuronal apoptotic rate was analyzed by TUNEL assay,the protein expression of TRPM7 was detected by Western blot,the mRNA level of TRPM7 was estimated by real-time PCR,the neuronal release of IL-1β and TNF-α in the serum was measured by ELISA.Results Compared with group C,the mR NA and protein levels of TRPM7,the neuronal apoptotic rate,the mRNA and supernatant protein levels of IL-1β and TNFα were significantly up-regulated in group OGD (P＜0.05),whereas the cell viability was decreased (P＜0.05).Compared with group OGD,the mRNA and protein levels of TRPM7,the neuronal apoptotic rate,the mRNA and supernatant protein levels of IL1β and TNF-α were significantly down-regulated in group SD (P＜0.05),whereas the cell viability was increased (P＜0.05).Compared with group SD,the mRNA and protein levels of TRPM7,the neuronal apoptotic rate,the mRNA and supernatant protein levels of IL-1β and TNF-α were significantly up-regula ted in group B (P＜0.05),whereas the cell viability was decreased (P＜0.05).Conclusion Sevoflurane attenuates apoptosis and inflammatory responses induced by OGD via reduction of the overex pression of TRPM7 in the hippocampal neurons.
