60 years senile autopsy cases w as about half of that of western countries,most of latent carcinomas were well a nd moderate differentiated.HGPIN was closely associated with prostatic adenocar cinoma.

Radiotherapy after breast conserving surgery for breast cancer is an important part of comprehensive therapy,and breast conserving surgery combined with radiotherapy for early stage breast cancer has been widely recognized.Modern radiotherapy techniques including three-dimensional conformal radiation therapy (3D-CRT) and intensity modulated radiation therapy (IMRT) have obtained reasonable application in breast conserving therapy.Radiation reaction and cosmetic result are important factors to evaluate radiotherapy after breast conserving surgery.Radiation reactions and cosmetic results of different radiotheraies are different and each has its own characteristics.

PET-CT plays a increasing important role in the treatment of lung cancer.Compared with CT,the advantage of PET-CT is obvious,which is more accuracy when determine a metastasis and identify inflammatory lesions.What's more,on the basis of the accuracy staging,PET-CT change many strategies which were based on traditional image,resulting in improving the treatment effect.While the assessment and prediction of the efficacy by PET-CT also exerted an important influence on the formulation of treatment strategies.

To investigate the mechanism of low responsiveness of cultured human intestinal epithelial cells (IECs) to LPS stimulation, IL-8 secretion level was detected by ELISA in supernatants harvested after the IECs were treated with LPS for 18h, and TLR4, TLR2, CD14 and MD2 mRNA were detected by reverse transcriptase-polymerase chain reaction(RT-PCR) and RNase protection assay(RPA). It was found that IL-8 was not detectable after IECs were treated with LPS and the expression levels of TLR4, TLR2, CD14 and MD2 mRNA of IECs were low and after exposed to LPS, the expressions of TLR4, CD14 and MD2 mRNA of IECs became further lower, whereas the expression of TLR2 mRNA didn't change obviously. The result suggests that low expressions of LPS signal transduction-associated receptors on IECs may be responsible for low response of IECs to LPS, so it confirms further that TLR4, CD14 and MD2 play important roles in transmembrane LPS signal transduction.

Objective To investigate the changes in the expression of phosphor-p38 mitogen-activated protein kinase (p-p38MAPK) in the distal cerebrospinal fluid contacting neurons (CSF-CNs) in rats with neuropathic pain.Methods Forty-eight male adult SD rats aged 2-3 months weighing 230-270 g were randomly divided into 2 groups (n =24 each): sham operation group (group S) and chronic constrictive injury group (group CCI).Neuropathic pain was induced by CCI.Sciatic nerve was exposed and 4 loose ligatures were placed on the sciatic nerve at 1 mm intervals with 4-0 silk thread.Thermal withdrawal latency (TWL) was measured with radiation heat stimulus before (baseline) and 1,3,5,7,14 d after CCI in 4 animals at eachtime point in each group.The animals were then sacrificed.30％ cholera toxin subunit B with horse radish peroxidase 3 μl was injected into the lateral ventricle at 48 h before the animals were sacrificed at each time point.The brain tissue in the region of the midbrain aqueduct was taken.The number of distal CSF-CN expressing p-p38MAPK was calculated.p-p38MAPK was detected by histochemical staining.Results The TWL was significantly shortened at 1-14 d after CCI in group CCI as compared with group S.The number of distal CSF-CNs expressing p-p38MAPK was significantly increased at 5-14 d after CCI in group CCI as compared with group S.Conclusion The distal CSF-CNs may be involved in the neuropathic pain induced by CCI through p38MAPK signaling pathway.p38MAPK may contribute only to the maintenance but not development of neuropathic pain.

18 F-FDG PET-CT has been widely used for the diagnosis,staging and assessment of therapeutic response in patients with non-small cell lung cancer (NSCLC).In particular,the technique plays an important role in the prediction of the response to therapy in patients with locally advanced NSCLC.It can dynamically observe the tumor tissue metabolism,and according to the changes of 18 F-FDG uptake by visual or quantitative analysis,before and after treatment,allow prediction of the early efficacy of locally advanced NSCLC with chemotherapy and (or) radiotherapy in clinical or sub-clinical levels.

Objective To investigate the effect of Niaochangshu capsule on urodynamics in bladder filling period of patients with post-menopause urethral syndrome of renal deficiency and blood stasis type.Methods A total of 36 patients with post-menopause urethral syndrome of renal deficiency and blood stasis type were randomly assigned to two groups:the trial group(24 patients were treated with Niaochangshu capsule) and the control group(12 patients were treated with Nilestriol).All patients were treated for 8 weeks.The changes of the urodynamic indexes in bladder filling period(the capacity of the bladder,the compliance of the bladder and the sensitivity of the bladder) were compared between the two groups.Results After treatment,the urodynamic index,including the maximum cystic capacity,the volume at the first desire to void and the cystic compliance were evidently improved in both of the trial group and the control group(P0.05).Conclusion Niaochangshu capsule is effective in treating the patients with post-menopause urethral syndrome of renal deficiency and blood stasis type.It can increase the cystic capacity and compliance,step down the sensitivity of the bladder.Its effect is similar to Nilestriol.

Objective:To investigate the eye movement anormalities of Obsessive-Compulsive Disorder (OCD) and their possible clinical significances. Methods: Exploratory eye movement in 57 patients with OCD according to DSM-IV criteria (27 medicated, 30 un-medicated) and 50 normal controls matched with sex, age and education were examined respectively. Results: Compared with normal controls, patients with OCD demonstrated low scores in most of the indices of exploratory eye movement. The rates of positive discrimiant score in OCD and normal controls were 37%(21/57) and 8% (4/50), respectively (X2 = 12.27, P

Objective: To explore the differential expression of tumor associated antigen CA X in tumor cells in vitro and in vivo . Methods: Tumor xenografts of the human lung adenocarcinoma cell line SpcA1 were grown in athymia mice. The antigen was measured before and after xenograft by Western blotting and flow cytometric analysis. Results: The antigen CA X was a glycoprotein with a molecular weight of 170 000 to 200 000 . Human lung adenocarcinoma cell lines regain expression of antigen CA X when xenografted into athymia mice. Conclusion: These data indicate that CA X synthesis in human lung adenocarcinoma cells SpcA1 is regulated by factors presented only in the xenograft.

[Objective]To evaluate the usability of endoscopy for the diagnosis of rhinorrhea.[Methods]An analysis was made on the rhinorrhea figure and letter data among 100 cases undergone endoscopy via the route of nasal cavity.All the cases were diagnosed as rhinorrhea.[Results]All of the cases were seen turbinates tumescence or mucous hyperemia and edema changes.Different changes reflected asthenia or sthenia of the 4 types of syndrome.[Conclusions]It is very valuable for combining endoscopy with TCM in the diagnosis with syndrome differentiation of rhinorrhea.
