Objective To investigate the reliability of CT-guided percutaneous lung biopsy pathological results in diag?nosing Non-small cell lung cancer (NSCLC). Methods Patients (n=91) were selected whose radiology examination re?vealed pulmonary masses but were failed to be confirmed with pulmonary lesion through sputum or bronchoscopy. Then, they were diagnosed as non-small cell lung cancer by CT-guided percutaneous lung biopsy. After that, they received surgical op?eration and biopsies were taken during operations for pathological analysis. Pathological results between from percutaneous lung biopsy (pathological types and using different analysis tools) and from surgical operation were compared. Results The coincidence rate of pathological type is 86.81%(79/91) using pathological results through percutaneous lung biopsy or oper?ation. Compared with the pathological results of operation, the coincidence rate of pathological type using percutaneous lung biopsy show no statistical significance [Squamous cell carcinoma 88.57%(31/35) vs Grandular cell carcinoma 86.27%(44/51) vs adeno-squamous carcinoma 80.00%(4/5),χ2=0.310,P>0.05];the coincidence rate of percutaneous lung biopsy pathologi?cal results using different approaches demonstrate statistical significance compared with surgical biopsy pathological results (χ2=9.698, P<0.05). The coincidence rate of pathological results obtained by Smear and biopsy [94.4%(51/54)] is higher than that of surgical biopsy pathological results using smear alone [60.0%(6/10)] and by biopsy alone [81.4%(22/27)]. Con?clusion Using CT-guided percutaneous lung biopsy, it can produce reliable results on pathological type of non-small cell lung cancer. But the reliability can be affected by different analysis approaches that were hired to exam samples from CT-guided percutaneous lung biopsy.

objective: To study the effects of laser engineered net shaping(LENS) in the manufacture of dental prosthesis. Methods: An experiment LENS system, including a 5 kW continuous wave CO 2 laser, a four-axes numerical control working table and powder feeding system, was built up, by which, a rectangular LENS component was made from Rene95 alloy powder. The microstructure of the component was observed with scanning electron microscope and ESA analysis. Results: The size of the component was 120 mm?15 mm?15 mm , and the wall of the component was perpendicular to the base. The microstructure of the component was made up of fine columnar dendrite with the length of 10～20 ?m, 10 times less than that of the cast made from the same material. The main elements of the powder distributed homogeneously,the negative effect of segregation could be limited and the properties of the component could be improved.Conclusion: The microstructure of components made by LENS is much better than that of those made by casting from the same material.

Objective To evaluate the association between stress hyperglycemia and clinical out-comes among patients with and without diabetes mellitns admitted to medical intensive care unit (MICU).Methods We reviewed the medical ICU records of 1016 consecutive patients admitted to Wu Han Univer-sity Ren Min Hospital. According to admission glucose level, 126 patients with debates and 890 patients without known debates were divided into group 1 ( <6 mmol/L), group 2(6 ～ 8mmol/L), group 3(8 ～10mmol/L), and group 4( > 10mmol/L). The primary end point of the study was in-hospital mortality. Secondary end points included length of hospital stay, length of ICU stay, the ratio of mechanical ventila-tion, blood transfusions, antibiotics and blood glucose treatment. Results The hospital mortality among patients without a history of diabetes mellitus was 4. 7%, 12. 1%, 20. 5%, 30. 3% in group 1, 2, 3, 4,respectively. The ratio of mechanical ventilation, blood transfusions, and antibiotics increased progressively as glucose values increased. Conclusions Hyperglycemia was a common disease, and it may be an impor-tant marker of poor clinical outcome and mortality in patients without history of diabetes.

Objective:To explore the role of nuclear transcription factor and the effect of nasal tolerance on EAN.Methods:75 male Wistar rats were divided into five groups: Group NS, EAN, EANL, EANM, EANH. The expression of IFN-?, TGF-?1, IL-10 mRNA and P65 protein were detected in spleen by using of RT-PCR and western blot.Results:The expression of IFN-? mRNA were the highest at early phase, those of TGF-?1 and IL-10 augmented significantly at recovery phase. In Group EANM and EANH, the severity of clinical signs and the infiltration of inflammatory cells decreased. IFN-? mRNA and P65 protein expression was lower than that in Group EAN, however, IL-10 and TGF-?1 mRNA increased markedly. At the same time, the expression of P65 protein were positively correlated with those of IFN-? mRNA, negatively correlated with those of TGF-?1 and IL-10 mRNA.Conclusion:NF-?B may play a vital role in EAN. Nasal administration of antigen may effectively prevent Wistar rat from inducing EAN in some degree, which may associate with the inhibition of NF-?B.

Objective To investigate the effect of matrix metalloproteinase(MMP-2) in the attack of exprimental autoimmune myositis(EAM) rats, and the effects of methylprednisolone on expressions of gene mRNA and protein of MMP-2. Methods The expression levels of MMP-2 in the peripheral blood, spleen lymphocytes and muscles were detected by using RT-PCR and immunohistochemistry techniques and was compared among EAM group,EAM with methylprednisolone treatment group (EAMM) and control group. Results ⑴ The degree of episode in EAMM group was lower than that of EAM group , and the infiltration of the inflammatory cells and the necrosis of the muscles were also mild in EAMM group. ⑵There was significant upregulation of the expression of the MMP-2 gene mRNA in the lymphocytes of peripheral bood and spleen of EAM rats as compared with that of the control,Elevation of the expression of MMP-2 protein in rats muscles tissues of EAMM group was observed obviously. However, the expression of the mRNA and the protein of MMP-2 was suppressed significantly in EAM group compared with control group. Conclusions The upregulation of the expression of MMP-2 may be correlated with the onset of EAM. Methylprednisolone may relieve the degree of the pathology of EAM by the downregulation of MMP-2 .
