0. 05), and were closely correlated to the clinical stage and the curative effect(P 0. 05). Conclusions: VEGF expression was contributes to the tumor neovascularization and tumor metastasis. Local control rate of VEGF positive tumor patients can be increased but their survival can not be prolonged by mono-chemotherapyonly only.

Purpose:To investigate prognostic effects of ex pressions of cyclooxygenase-2(COX-2) and epidermal growth factor receptor(EGFR )in non-small-cell lung cancer(NSCLC).Methods:Expression of COX-2 and EGFR in the resected tumors of 60 patients with NSCLC were detected with the method of immunohistochemistry st aining.We used ?2 test and COX regression analysis to compare difference in e xpressions of COX-2 and EGFR in differentiation grade of squamous and adeno-ca rcinoma cells of the lungs and their relationships with the patients survival in NSCLC.Results:The positive rates for COX-2 were 73% and 33% in adeno carcinoma and squamous carcinoma,respectively.The expression rate was significan tly higher in the adenocarcinoma than in the squamous carcinoma.Expressions of C OX-2 and EGFR in NSCLC were not related to patientsage and sex,differentiation grade of tumor cells,TNM staging,size of promary tumor and lymph nodes metastasi s.Median survival time was 30 months and 16 months in COX-2 expression levels o f “+” and of “++”,34 months and 15 months in EGFR expression levels of “+” and of “++” and was significantly lower than in those without expression of C OX-2 or EGFR(P

Background and purpose:Angiofollicular lymphoid hyperplasia(Castleman's disease,CD) is a rare kind of abnormal disease with lymphoid hyperplasia. We analyzed the clinical data of 21 patients with pathologically-confirmed CD. Methods:Twenty-one cases,including 10 males and 11 females with a mean age of 38.6 years,with CD were collected from January 1971 to December 2007 in this study. The disease was divided into localized type(n=19) and disseminated type(n=2) . The clinical data,CT images and pathological and surgical results were restrospectively analyzed. Results:All cases were categorized as hyaline vascular type. In 19 cases with localized type of CD,the lesion presented as a solitary soft-tissue mass with a mean diameter of 5.2 cm,located at the left and right hilus of the lung(n=3 and 2 respectively) or in the interior lung(n=3) ,in the thoracic wall(n=2) or in the mediastinum(n=9) . Two cases of disseminated type were characterized by many groups of thoracic lymphadenopathy with a mean diameter of 2.3 cm,without other organ involvement. On plain CT scan,the mean CT value was 42 Hu. After contrast administration,obvious homogeneous enhancement was observed in arterial phase with CT value of 112 Hu. The preoperative misdiagnosis by CT was 90.5%. Conclusion:CD have no specifi c CT characteristic,its verifi cation is mainly based on pathologic examination. Surgical resection for localized type of CD is curative,but for disseminated CD,multidisciplinary therapies are recommended.

Objective To propose a new observation procedure of blood pressure after the surgery of fiducial implantation for cyber knife, using the statistical analysis of the measurements of blood pressure at different time after the surgery. Methods By taking 200 patients after the surgery of fiducial implantation, the usual blood pressures and the blood pressures at different time after the surgery were compared statistically. Results Based on the statistical analysis, the usual blood pressures were statistically different from the blood pressure immediately after surgery, as well as the blood pressure at 0.5 hours after surgery [ systolic pressure (131.60 ±16.86), (129.08 ±14.77) mmHg (1 mmHg=0.133 kPa) vs. (123.00 ±11.80) mmHg, t=2.897 and 2.308, P<0.01 or 0.05;diastolic pressure (83.49±10.01), (81.75±8.99) mmHg vs. (78.22±7.59) mmHg, t=2.901 and 2.066, P<0.01 or 0.05]. The blood pressures measured at the other time after surgeries were not statistically different from the usual blood pressures, P>0.05. Conclusions Measuring the blood pressures at the time of 0, 0.5, 3.5 hours after the surgery can not only assure the complete recovery of the patients after the surgery, but also greatly reduce the work of nurses.

ObjectiveTo evaluate the relationship between metabolic syndrome (MS) and benign prostatic hyperplasia ( BPH ) in men over 50 years old.Methods Male participants over 50 years old form a community in Beijing were randomly selected.Age,blood pressure,past history,and the international prostate symptom score (IPSS) were recorded.Plasma glucose,triglyceride,high density lipoprotein,prostate specific antigen (PSA),prostatic volume,and Qmax were measured.The morbidity and severity of BPH were compared with statistical analysis.ResultsFour hundred and forty men were enrolled,and were divided into 2 groups:MS group (n =105) and non-MS group (n =335).Compared to the non-MS,non-obesity,and non-hyperlipidemia group respectively,the morbidity of BPH was higher in MS,obesity and hyperlipidemia group (33.3％ vs.11.9％,P ＜ 0.05 ; 20.4％ vs.11.8％,P ＜ 0.05 ; 25.0％ vs.14.1％,P =0.007).The morbidity of moderate and severe LUTS in MS group was higher than non-MS group (61.9％ vs.31.3％,P ＜ 0.05).Significant differences were found in IPSS,prostate volume and PSA between the MS and non-MS groups ( P ＜ 0.05 ),but not found in Qmax ( P =0.069).Obesity,hyperlipemia and diabetes mellitus were risk factors of BPH (OR 1.75,95％ CI 1.40 -21.82,P =0.041 ; OR 3.36,95％ CI 2.34-48.13,P=0.037; OR 2.08,95％ CI 1.32-13.67,P=0.045). Conclusions There is higher morbidity of BPH in MS patient.MS could increase IPSS and prostate volume,and reduce PSA in BPH patient.Obesity,hyperlipemia and diabetes mellitus are risk factors of BPH.MS should be considered when treating BPH.

Purpose To investigate the clinicopathological features of adolescent mixed epithelial and stromal tumor of the kidney ( MESTK) and improve recognization of this rare disease. Methods Clinicopathological and immunohistochemical characteristics of MESTK occured in 17-year-old girl were studied. Reviewed the related literatures, clinical and pathological characteristics of adoles-cent MESTK were analysed comprehensively. Results Congenital perineal spill was the main clinical manifestations. Microscopically, the tumor showed nodules and was composed of a mixture of epithelial and stromal elements. Glands were lined with columnar or cilia-ted columnar cells. Stromal cells surrounding glands seemed like ovaries and away from glands seemed like the differentiation of smooth muscle. Immunohistochemical staining revealed that the epithelial cells were positive for CK7 and vimentin. Stromal cells expressed desmin, smooth muscle actin ( SMA) , ER and PR. It was noteworthy that stromal cells away from glands expressed desmin. Conclu-sions As a kind of rare benign neoplasm of kidney, MESTK often occurs in perimenopausal women. But MESTK can also occur in ad-olescence, and has nothing to do with the use of hormone. Therefore, the renal tumor occurred in teenagers with biphasic differentiation should be differentiated from MESTK.

Objective To analyze the clinical,radiological and pathdogical characteristics of idiopathic lymphoid interstitial pneumonia (idiopathic LIP) and to discuss its diagnosis,treatment and prognosis.Methods Respiratory physicians,pathologists and radiologists together retrospectively analyzed the clinical,chest roentgenogram,computerized tomography,pathologicM,diagnostic and therapeutic data of 3 patients with idiopathic LIP confirmed by lung biopsy.and reviewed the relevant literatures.Results The major symptoms of the 3 cases of idiopathic LIP were prgressive dyspnea and dry cough.Higher levels of γ-globulins in serum were found in all the cases.The characteristic radiographic manifestations were bilateral diffuse nodules and cysts.The pathologic feature was diffuse interstitial inflammation with polyclonal lymphocytes infiltration,especially with plasma lymphocytes.Corticosteroids and cytotoxic agents were used and good response to therapy was observed in the cases.Conclusions Idiopathic LIP has some characteristics on the clinical,radiological and pathological features,but the best diagnostic method depends on a clinical-radiological-pathological approach.The disease usually shows good response to combinative therapy of corticosteroids and cytotoxic agents.

Objective: To explore the impact of ticagrelor on myocardial microcirculation in patients of non-ST elevation myocardial infarction (NSTEMI) after percutaneous coronary intervention (PCI). Methods: A total of 80 NSTEMI patients treated in our hospital from 2015-03 to 2015-12 were enrolled. All patients received coronary angiography (CAG) and PCI, they were randomly divided into 2 groups: ticagrelor (TA) group and clopidogrel (CA) group, n=40 in each group. The baseline condition, PCI related parameters, plasma levels of SOD, MDA at pre- and 24h, 72h post-PCI were compared, the incidence of major adverse cardiac events (MACE) within 30 days after PCI was also compared between 2 groups. Results: The baseline condition, proportion of infarction-related vessels, average length and diameter of implanted stents were similar between 2 groups, all P>0.05. Compared with CA group, TA group had the less post-operative CTFC in LAD and RCA, P<0.05; while CTFC in LCX was similar between 2 groups, P>0.05. The ratios of acute pre-operative, post-operative TIMI grade 3 and slow flow incidence were similar between 2 groups, P>0.05. The peak values of CK-MB and cTnI in TA group were lower than CA group, P<0.05. Compared with baseline condition, MDA levels at 24h and 72h post-operation were increased in both groups, all P<0.001; compared with CA group, TA group had the lower MDA level at 24h post-operation, P=0.023, MAD was further reduced at 72h post-operation in TA group, P=0.043. Compared with baseline condition, SOD levels at 24h and 72h post-operation were decreased in both groups, all P<0.001; compared with CA group, TA group had the higher SOD level at 24h post-operation, P=0.013, SOD was elevated at 72h post-operation in both groups, the elevation was more obvious in TA group, P=0.049. The incidence of MACE was similar between 2 groups within 30 days of PCI,. Conclusion: Ticagrelor could improve myocardial microcirculation in NSTEMI patients after PCI; it was safe and without obvious adverse effects.

BACKGROUNDTo explore the clinicopathological changes of non-small cell lung cancer tissues after neoadjuvant chemotherapy with MVP (MMC+VDS+DDP) regimen and its concordance with clinical evaluation, and to study the clinical value of neoadjuvant chemotherapy.

METHODSA total of 84 patients with NSCLC were randomized into combinated therapy group (42 cases) and surgical group (42 cases). The combinated therapy group were given MVP regimen for 2 cycles before operation and 2-4 cycles after operation, however, the surgical group only received surgical treatment. The efficacy of preoperative chemotherapy were determined by pathologic examination under light microscope and electron microscope and clinical evaluation.

RESULTSCombinated therapy group showed various degrees of degeneration and necrosis of tumor cells, which was not found in surgical group. The overall response rate of neoadjuvant chemotherapy was 59.5% (25/42) by both pathological and clinical evaluation. The coincidence ratio of the two evaluation methods was 71.4% (Kappa value=0.407,P < 0.01). Between the two groups, there was a significant difference in total survival rate (P=0.047). And further analysis showed that survival rate was remarkably different in patients with stage III between the two groups (P=0.037), but not in those with stage I and II (P > 0.05).

CONCLUSIONSDegeneration and necrosis with fibrosis are the main pathological phenotypes of the primary lesion after induction chemotherapy, which can be showed by clinical evaluation to chemotherapy efficacy. The preoperative and postoperative adjuvant chemotherapy may be benefical to patients with stage-III NSCLC.
