Objective To discuss the influence of nursing intervention on sleep quality and postoperative comfort of patients with percutaneous coronary intervention(PCI). Methods We divided 96 patients who were to receive PCI into the test group and control group with 48 patients in each group.The control group received routine nursing while the test group were given systemic nursing intervention based on routine nursing intervention.The sleep quality and incidence rate of complications were compared. Results The sleep quality in the test group was better than that of the control group (P ＜ 0.01 ).The ineidience of waist-back pain,dysuria,induced emiction,eatheter emietion,anaesthesia of lower limbs,fidget in the test group also decreased compared with the control group(P ＜ 0.05). Conclusions Systemic nursing intervention could improve the sleep quality and postoperative comfort for PCI patients

AIM:There are some reports about the treatment of spinal cord injury with neural stem cells(NSCs) transplantation,but the ideas about the transplantation time and patterns and detection indexes are still different.In this study,the effects of cryopreserved NSC transplantation on the axonal regeneration after the spinal cord injury in rats were observed.METHODS:The experiment was carried out in the experimental animal center of China Medical University from June 2005 to June 2006.①Thirty-six adult Wistar rats,either male or female and 250-300 g,were provided by the experimental animal department of China Medical University.Neural stem cells were isolated from 10 neonate rats and cultured.All treatments for animals were accorded with the animal ethical criteria.②NSCs at logarithmic phase were cryopreserved at-70 ℃ for 2 weeks and labeled with 5-bromodeoxyuridine(Brdu) after rewarming.After the models of spinal cord injury were established,the NSCs were transplanted into the injured site immediately.Thirty-six rats were randomly divided into NSC transplantation group,DMEM solution group,and control group.③NSC survival and migration were detected by immunohistochemistry,and the reconstruction of spinal cord were detected by horseradish peroxidase(HRP) staining.RESULTS:Of the 36 spinal injured model rats,4 died of overdose of anesthesia,and 5 died of infection,but all were supplemented.Brdu-labeled positive NSCs were detected in the injured spinal cord after transplantation on the 7th day,and increased on the 14th day,then gradually decreased since the 28th day till disappeared.The number of HRP positive cells in transplantation group was significantly higher than DMEM solution.CONCLUSION:Cryopreserved NSCs can survive in the injured site after transplantation and promote the reconstruction of axoplasm pathway of injured spinal cord.

Objective To explore the effect of three-dimensional conformal radiation dose fractionation treatment of advanced non-small cell lung cancer(NSCLC).Methods 75 NSCLC patients were treated with hypofractionated 3DCRT( observation group),while 73 cases were treated with conventional fractionated radiotherapy (control group).The efficacy and adverse reactions were observed;Survival after treatment were followed up in 1,2,3 years.Lung function was detected before and after radiotherapy treatment,including FVC,FEV1 and CLCO.Results The total effective cases of control group were 47 cases patients ( 64.4％ ),observation group's was 60 cases ( 80.0％ ),total effective rate had statistically significant difference ( x2 =4.50,P ＜ 0.05 ).Survival of control group after treatment in 1,2,3year were 50.7％,24.7％,8.2％,the median survival was 13 months,observation group's were 73.3％,45.3％,20.0％,and 19 months.The survival of these two groups was statistically different (x2 =8.07,6,94,4.22,all P ＜ 0.05 ).The patients blood system side effects of observation group were significantly lower than the control group ( x2 =4.73,P ＜0.05 ) ;acute radiation pneumonia,esophagitis of these two groups had no significant difference in the incidence( P ＞ 0.05 ).Conclusion Hypofractionated 3DCRT treatment of advanced NSCLC had good effect,and its adverse reactions was low,and it was worthy of clinical application.

Objective To investigate the clinical effect of hyper-fractionated three-dimensional conformal radiotherapy (3DCRT) combined with transcatheter arterial chemeembolization (TACE) for heating patients with inoperable primary liver cancer.Methods One hundred and two patients with inoperable advanced primary liver cancer were divided by random digits table method into control group with 49 cases treated with TACE and observation group with 53 cases treated with hyper-fractionated 3DCRT combined with TACE.The short-term efficacy,adverse reaction and survival rate of the 1st,2nd and 3rd year and serum alpha-fetoprotein (AFP) expression after treatment in two groups were observed.Results The complete remission rate,progress rate and total efficiency were 17.0％ (9/53),11.3％ (6/53),73.6％ ( 39/53 ) in observation group,2.0％( 1/49 ),28.6％ (14/49),51.0％(25/49 ) in control group.There were significant differences between two groups (P ＜ 0.05).There was no statistical significance in adverse reactions between two groups ( P ＞ 0.05 ).The survival rates of the 1 st,2nd and 3rd year in control group were 51.0％ ( 25/49 ),28.6％(14/49),14.3％(7/49),the median survival time was 15 months;while those in observation groupwere 71.7％(38/53),52.8％(28/53),39.6％(21/53) and 20 months.The survival rates of the 2nd and 3rd year in observation group were significantly higher than those in control group respectively (P ＜0.05 or ＜0.01 ).The rate of patients with no obvious serum AFP protein change between observation group [ 9.8％(4/41) ] and control group [ 31.6％(12/38) ] had statistical significance (P ＜ 0.05).Conclusion Hyper-fractionated 3DCRT combined with TACE for treating patients with inoperable primary liver cancer has good clinical efficacy,it is worthy of clinical practice.

Objective To analyze the features of supraclinoid internal carotid aneurysms. The experience and mistakes in the microsurgery of supraclinoid internal carotid aneurysms were summarized to improve the results. Methods The data of 24 cases of supraclinoid internal carotid aneurysms that were operated from May 2004 to March 2009 were reviewed. There were 6 cases of small or middle aneurysms, 18 cases of large or giant aneurysms. The operative methods included direct clipping, partial excision of aneurysm with reconstruction of the parent artery, aneurysm trapping with extracerebral/intracerebral (EC-IC) bypass, etc. Results Among the 24 cases, 8 cases had good results. Ten cases occurred hemiplegja post operation immediately, with 5 cases recovered to grade IV ,3 cases had aphasia,5 cases with vision acuity fall,4 cases had abnormal eyeball movement,2 cases had continued coma and died finally. Second operations were performed in 3 cases. The total operation rate of well results was 66.7% (16/24). Mortality rate was 8.3% (2/24). Conclusions The operative technique of the supraclinoid internal carotid aneurysms is difficult because of the location and the large size of the aneurysms. The temporary obstruction' of the parent artery is often needed, so the aneurysm can be partially resected and clipped. The results of clipping of large or giant aneurysms are better than the other methods. But in large or giant aneurysms that had thrombus, the EC-IC bypass is needed to prevent large infarction. The bypass procedure may induce some severe complications that result in some poor outcome.

Background and purpose: It has been reported that activation of Notch1 could strongly inhibit proliferation of HPV (human papilloma virus)-positive HeLa cells by down-regulation of the E6 and E7 genes. The aim of this paper was to investigate the role of the Notch signaling pathway in growth arrest of EC109 cells in vitro and the molecular mechanism. Methods: EC109 cell lines, a well differentiated human ESCC (esophageal squamous cell carcinoma) cell line with HPV18-positive, was used in the study. Exogenous intracellular domain of Notch1(ICN) was transfected into cultured EC109 cells by lipofectamine transfection, the proliferation of the transfected cells was measured by an MTT assay. Cell cycle distribution was analyzed by flow cytometry. Human papilloma virus type 18 (HPV18) E6/E7 mRNA expression was detected by RT-PCR, and p53 protein expression was detected by Western blot.Results: Activation of Notchl signaling resulted in inhibition of EC109 cell proliferation with the induction of G_2/ M arrest. There was a significant difference in terms of the percentage of G_2/M phase cells among the ICN-transfected group (42.57±1.57)% and the non-transfected group (1.88±0.66)% or the empty plasmid transfected group (1.99±1.02)% (P<0.01). Down modulation of HPV18 E6/E7 gene expression and upregulation of p53 expression was (2.15±0.23) in ICN-transfected group higher than non- transfected group (0.45±0.07) and empty plasmid transfected group (0.46±0.02) (P<0.01). Conclusion: Repression of HPV18 E6/E7 expression by Notch1 signaling results in growth suppression of HPV18-positive EC109 cells with concomitant activation of p53-mediated pathways.

The paper is to establish a method for simultaneous determination of 5 kinds of alkaloids in ephedra and poppy which are in Kechuanning tablets. Solid-phase extraction (SPE) was adopted in pretreatment, and a UPLC method with 2 different wavelengths had been developed: 210 nm for the detection of morphine, codeine phosphate, ephedrine hydrochloride and pseudoephedrine hydrochloride, and 251 nm for papaverine hydrochloride. The column used was Acquity UPLC BEH C18 (100 mm x 2.1 mm ID, 1.7 microm) with linear gradient elution using acetonitrile and 0.1% phosphoric acid. The flow rate was 0.4 mL.min-1, and the column temperature was 30 degrees C. The linear response range was 0.375 0 - 12.50 microg.mL-1 for morphine, 0.064 32 - 2.144 microg.mL-1 for codeine phosphate, 0.030 06 - 1.002 microg.mL-1 for papaverine hydrochloride, 1.126 - 37.52 microg.mL-1 for ephedrine hydrochloride, 0.287 8 - 9.592 microg.mL-1 for pseudoephedrine hydrochloride (r = 0.999 7). The average recoveries of these compounds were 99.26%, 100.6%, 95.29%, 100.1% and 97.48%, respectively. This is a more reasonable and credible method of quality control for Kechuanning tablets.

Objective To study the effect of obesity and overweight on the hospital stays and total course of common pneumonia in children and the possible reasons.Methods A total of 455 children with common pneumonia aged from 2 to 7 years were enrolled in this study,including 147 obese children,141 overweight children and 167 normal weight children.Then all the children were divided into 2 groups based on age:≥ 2-4 years group and ≥ 4-7 years group.The information of the patients was collected from the medical records management system of our hospital,and including gender,age,weight,height,hospital stays,total course,peripheral blood cell counts (white blood cell,neutrophil,monocyte and lymphocyte),C-reactive protein (CRP),erythrocyte sedimentation rate (ESR),IgG,IgA,CD4 + T,CD8 +T and the history of recurrent pneumonia.Results In ≥ 2-4 years group,the average length of the hospital stays of common pneumonia in obese and overweight children was longer than that in the normal weight children(P =0.037,0.009),and the total course of common pneumonia in obese children was longer than that in the normal weight children (P =0.014).In ≥ 4-7 years group,the average length of the hospital stays and total course of common pneumonia in obese and overweight children were longer than those in the normal weight children (the hospital stay:P =0.002,0.000,the total course:P =0.004,0.001).In ≥2-4 years group,the peripheral blood cell counts(white blood cell,neutrophil,monocyte and lymphocyte),CRP,ESR,IgG,IgA,CD4 + T,CD8 + T,CD4 + T/CD8 + T and the history of recurrent pneumonia were of no significant difference among obese,overweight and normal weight children (all P ＞0.05).In ≥4-7 years group,the peripheral blood cell counts(white blood cell,neutrophil,monocyte and lymphocyte),and ESR were of no significant difference among obese,overweight and normal weight children (all P ＞ 0.05),but the levels of IgG,CD4 + T and CD4 + T/CD8 + T in obese and overweight children were lower than those in the normal weight children,and the obese children were more notable in this aspect (P ＜ 0.05).And obese and overweight children were more likely to suffer from recurrent pneumonia.Conclusions Obese and overweight children with common pneumonia aged from 2 to 7 years may need longer hospital stay and total course than normal weight children.Impaired immunity may be the main reason for the ≥4-7 years group,but in the ≥2-4 years old group,it may be attribute to some non-immune factors.
