The TNM staging is the most common tumor staging system of lung cancer.The new revisioned 7th lung cancer TNM staging is published by the international association for the study of lung cancer (IASLC) in the 13th world conference on lung cancer.Accurate clinical staging depends on the multi-analysis from medical histroy,clinical examination,imaging examination and invasive test,which has important significance for guiding the treatment of lung cancer.The 7th lung cancer TNM classification has been revised respectively from the primary focus,lymph node metastasis and remote viscera metastasis,so as to make it more accurately corresponding to the prognosis of patients.

0 but was obviously lower than P_ sys in no endoleak. P_ sac approached P_ sys in type Ⅰ and type Ⅳ endoleaks. Some researches showed that P_ sac in type Ⅱ endoleak was higher than that in no endoleak and even approached P_ sys , however the other researches showed that P_ sac in type Ⅱ endoleak was lower than that in no endoleak. Conclusion Postoperative P_ sac dropping greatly eliminated the risk of aneurysm rupture, which symbolized the success of endovascular therapy. Even if the type Ⅰ endoleak of small size might lead to obvious elevation of P_ sac , which necessitates management. The impairment and management tactics of type Ⅱ endoleak remained equivocal, which required further study.

Ocular surface disorders can be caused by the drug-derived toxicity,adverse effect and abuse of eye drops,and usually these disorders present with unspecific and untypical clinical findings.So the eye abnormality induced by topical administration of eye drops often is confused with some corneal inflammatory diseases.In addition,pathogenic mechanisms vary widely due to the different types of eye drops.Therefore,difficulty of diagnosis and poor curative effect often is a challenge for us.Ophthalmologist should be aware of the toxicity derived eye drops on ocular surface.Several noticeable problems of diagnosis and treatment of drug-derived keratopathy were elaborated in this paper.

Objective: To evaluate the value of Cook MOB-15 system in guiding wire insertion during endoscopic retrograde cholangtopancreatography (ERCP). Methods: The clinical data of 51 patients who received Cook MOB-15 system-guided wire insertion during ERCP between Jan. 2005 to Dec. 2007 were retrospectively analyzed. Forty patients who received conventional ERCP catheter for malignant jaundice between Jan. 2002 and Dec. 2004 were taken as control. The successful insertion rates were compared between the 2 groups. Results: The successful insertion rate was 90.2% (46/51) in the Cook MOB-15 system group and 72.5% (29/40) in the conventional group; there was significant difference between the 2 groups (P<0. 05). Conclusion: The Cook MOB-15 system can significantly raise the successful insertion rate in ERCP.

Objective To investigate the changes in trafficking of GluRl-containing AMPA (GluR1-AMPA) receptor and GluR2-AMPA receptor from cytoplasm to cell membrane in the spinal cord dorsal horn in a rat model of incisional pain.Methods Thirty-two adult male SD rats aged 6-8 weeks weighing 280-300 g were randomly divided into 2 groups:control group (group C,n =8) and incisional pain group (group Ⅰ,n =24).An 1 cm long incision was made in the plautar surface of right hindpaw according to Brennan et al.in group Ⅰ.Cumulative pain score (CPS) and paw-withdrawal threshold to yon Frey stimuli (PWT) were measured at 3 h and day 1 and 3 afar incision ( T1,2,3 ).The animals were sacrificed after pain behavior assessment.Their lumbar segments of the spinal cord (L3-6) were removed.The expression of GluR1 and GluR2 in cell membrane and cytoplasm in spinal cord dorsal horn was determined by Western blot analysis.The co-expression of Stargazing with GluR1 and GluR2 in the spinal cord dorsal horn was examined by co-immuno-precipitation.Results The CPS was increased and PWT decreased; the GluR1 expression in cytoplasm was decreased while the expression of GluR1 in cell membrane and the co-expression of Stargazing with GluR1 were up-regulated in group Ⅰ as compared with group C.There was no significant change in the expression of GluR2 in cytoplasm and cell membrane and the co-expression of Stargazing with GluR2 in group Ⅰ as compared with group C.Conclusion GluR1-AMPA receptor transfers from cytoplasm to cell membrane but GluR2-AMPA receptor does not in rats with incisional pain.

Objective To understand the influence of nursing home service experience on humanistic caring ability of nurses.Methods Using the phenomenological method,15 clinical nurses after participation of nursing home service were interviewed,and the data were analyzed using 7 step Colaizzi method.Results 3 themes were extracted:service experience,the understanding of humanistic nursing care,influence of service experience on humanistic caring ability of nursing.Conclusions The participation of nurses in the nursing home services can promote the humanistic caring ability of nursing,which is a positive way of cultivating the ability of humanistic care ability.

Objective To explore the risk factors for urinary tract infections in type 2 diabetes mellitus(T2DM )by analyzing the pathogens distribution characteristics and drug sensitivity. Methods A total of 3 ,065 T2DM patients were retrospectively analyzed for the clinical and etiological characteristics of urinary tract infections in T2DM. All patients enrolled in the study were divided into two groups :T2DM with urinary tract infection group (n= 210) and simple T2DM group (n= 132). Data harvested were analyzed by SPSS 19.0. Results Of 3 ,065 patients with T2DM the incidence of urinary tract infection was 6.85%. Compared with T2DM group ,patients in T2DM+ urinary tract infection group were older , with longer duration of diabetes ,higher levels of FPG ,urea nitrogen ,creatinine and 24 hUAlb ,and lower levels of serum albumin ( P< 0.05 ). Logistic regression analysis showed that age ,gender ,duration of diabetes and 24 hUAlb were risk factors and albumin was protective factor for urinary tract infection in T2DM. 84.2% was gram-negative bacteria among the 210 isolated strains of pathogenic bacteria. The top three pathogens were Escherichia coli (65.2% ) ,Enterococcus faecalis (6.2% ) and Klebsiella pneumoniae (5.2% ). Gram-negative bacteria had high sensitivity to Imipenem (100% ) ,Cefoperazone sulbactam (99.2% ) and Amikacin (99.2% ) but low sensitivity to cephalothin (38.1% ) ,piperacillin (35.7% ) and amoxicillin (28.2% ). Conclusion T2DM patients who have the factors including female ,advanced age , long course of diabetes and renal insufficiency are prone to suffer from urinary tract infection. Gram-negative bacteria are the most common pathogens in T 2DM patients with urinary tract infection but bacteria spectrum has changed with percentage of multiple resistant bacteria rising dramatically.

Objective For establishing a effective method of gene polymorphism. Methods Polymorphism of CYP1A1 were detected by allele specific amplification and allele specific amplification-ELISA in this study.Results The results of two testing methods were same except one sample.PCR products were labeled with Dig in ASA-ELISA,then the PCR products were detected by specific and sensitive ELISA.The assay detection was 100-fold more sensitive than gel detection of ASA PCR products.Conclusion It was simple and short time,but it was more expensive.

0.05).The expression percentage of IL-4 of CD3+CD8-T lymphocytes cells in peripheral blood of the patients in group A(4.0%?2.8%)was significantly lower than that in group B and C(7.9%?5.5% and 10.2%?7.5%,P0.05).The level of serum sCD30 in the patients of group A(20.2?12.4ng/ml)was significantly higher than that of group B and C(7.8?3.1ng/ml and 7.6?3.0ng/ml,P0.05).ROC curve analysis indicated that when the ratio of Th1/Th2 was at the cut-off value of 1.95,the sensitivity and specificity to identify CRAD caused mainly by immune injury was 80% and 90%,respectively;and when the level of serum sCD30 was at the cut-off value of 10ng/ml,the sensitivity and specificity to identify CRAD caused mainly by immune injury was 93.3% and 86.7%,respectively.Conclusions Disequilibrium of Th1/Th2(drift to Th1)and raised level of serum sCD30 exist in most of the patients with CRAD which was caused mainly by immune injury.It is with high sensitivity and specificity to identify the CRAD by determining the ratio of Th1/Th2 of CD3+CD8-T lymphocytes cells in peripheral blood and the level of serum sCD30.
