The experiment was designed to simulate active training with animal model. A dynamic and static trai-ning program for adult rats was carried out 30-60'/day, lasted from 25 to 232 days. The rats were killedperiodical1y in batches and the sections were prepared for exploring histological changes in knee and ankle areas on L/M. Degenerative cbanges in quadriceps and gastrocanemius muscles appeated by degrees aftet a period of in-tensive training. The nuclei proliferated in chains or clusters arranged in the center and the edge of thefibers. The number of nuclei for each chain or cluster could be as much as 20 or 30. Meanwhile, therewere also ischemic changes in small vessels. All these were the characteristic changes induced by mictotraumain muscles under repeated active and strenous training. In calcaneal and patellar ateas, there were changes of cartilaginous degeneration, necrosis and prolifera-tion (cartilaginous exostoses and osteophytes) too. The typical changes of enthesiopatby---degeneration, necrosis and proliferation (osteophyte) could beobserved in calcaneal tendon and its insertion area and in superior insertion atea of lower patella. The occur-rence of enthesiopathy in this experiment migbt be related to tke stress of traction force within muscle andcartilage during running in upward treadmill.

0 05). Conclusion Femal, splenomegaly and increase of the MPV width and PVP were the risk factors inducing PVT in liver cirrhosis patients, while liver function, BPC, PT, ect, may not be related to the formation of PVT.

Objective To investigate the effect of the formation of portal vein thrombosis(PVT) on the nature course of liver cirrhosis(LC). Methods Patients with LC during 1995 2002 in our hospital were reviewed and forty eight cases of LC with PVT were included in the study. The PVT was diagnosed by color Doppler and/or CT. Fifty two cases of LC patients without PVT were chosen as controls. The liver function, coagulation function and the aspects of portal hypertension etc. were compared between these two groups. The average diameter of main portal vein(MPV) and spleen vein (SPV) were measured by color ultrasound. Results In 75.0% of patients, thrombosis happened gradually without symptoms, and 85.4% happened in the MPV trunks. The splenomegaly and width of MPV were the risk factors for the formation of PVT ( P = 0.003 and 0.010). In PVT group, the average width of MPV and SPV was 1.48 cm ?0.26 cm and 1.23 cm ?0.38 cm , respectively, significantly wider than 1.37 cm?0.22 cm and 1.05 cm ?0.30 cm in controls( P =0.037 and 0.031). In addition, larger size of spleen,more severe esophageal varices, higher rate of severe variceal haemorrhage and larger volume of ascites after portal vein thrombosis were shown in the study group( P

Purpose To explore the pathological feature of urinary exfoliated cell examination and influence factors by retrospectively comparing the coincidence of diagnosis between urinary exfoliated cell examination and histopathologic results of cystoscopic biopsy. Methods 735 patients underwent both urinary exfoliated cell examination and histopathologic biopsy of cystoscope evaluation from No-vember 2010 to July 2014 in Peking University Shougang Hospital were enrolled in this study. The urinary exfoliated cells were treated with Pap staining, while the histopathologic biopsy were dealt with HE staining. All cases were divided into three groups according to the diagnosis of urinary exfoliated cell examination:negative group ( no cancer or atypical cell detected) , suspicious group ( atypical cell detected) and positive group ( cancer cell detected) . These above diagnoses were confirmed with the histopathologic biopsy. ROC curve analysis, Cochran-Armitage trend test and logistic regression analysis were performed to evaluate the sensitivity and the specificity of urinary exfoliated cell examination as well as the relationship between diagnoses with age and sex. Results The age range of 735 patients (551 male and 184 female) was 28 ~91 years and the median age was 69 years. There were 187 patients in the positive group, including 184 malignant and 3 false-positive cases. The suspicious group, including 186 cases, consisted of 67 malignant, 119 benign reactive changes. Of all 362 cases in the negative group, malignant tumor was detected in 90 cases. For histologic diagnosis, the AUC of ROC(95%CI)was 0. 800 (0. 767~0. 834), displaying significant difference as compared to the histological pathological diagnostic results(P<0. 001). As the cyto-histologic diagnostic level elevated from negative, suspicious to positive, the results of Co-chran-Armitage trend test showed significant differences(Z=15. 83, P<0. 001). If standardized with the histopathologic biopsy re-sults, the AUC (area under curve) of urinary exfoliated cell examination was 0. 800 (0. 767~0. 834) in ROC curve analysis was sig-nificantly larger (P<0. 001). Furthermore, we also found in Logistic regression that the incidence of cancer was 1. 04 (1. 03~1. 05) times higher if aged one year older ( P<0. 001 ) , while there was no significant relationship between the incidence and the sex ( P=0. 655). Conclusions The coincidence rate of urinary exfoliated cell examination increases with the malignant degree. A positive cor-relation is detected between age and the incidence of malignant tumor. Detailed clinical material can markedly improve the sensitivity and accuracy of cyto-histologic diagnosis.

Objective To explore the clinical significance of serum vascular endothelial growth factor (VEGF) level in nasopharyngeal carcinoma patients. Methods Serum VEGF level of 55 nasopharyngeal carcinoma patients were measured by sandwich enzyme?- linked immunosorbent assay (ELISA). 40 normal healthy volunteers served as control. Results Serum VEGF level of nasopharyngeal carcinoma patients was significantly higher than that of control group (P =0.000); Serum VEGF level was significantly higher in advanced nasopharyngeal carcinoma stage (stage Ⅲ ~Ⅳ) than that in early stage(stageⅠ ~Ⅱ) (P =0.003); Serum VEGF level with nasopharyngeal carcinoma patients with lymphnode metastasis was significantly higher than that of patients without lymphnode metastasis. There was no significant relationship compared serum VEGF level in nasopharyngeal carcinoma patient's gender, age and pathological types. Conclusions Serum VEGF can be used as a marker of nasopharyngeal carcinoma for diagnosis and monitoring the progress and the prognosis of the disease.

The percentage of NK cells in spleens from mice in experiment group [(26.49±1.89)%] was significantly higher than that of control group [(13.94 ±1.31)%, P<0.05)] and empty vector group [(19.12 ±1.69)%, P<0.05)].Conclusion Transfection of r-Ad-hIFN-λ1 and expression of hIFN-λin skeletal muscle could significantly inhibit the growth of gastric cancer by inducing tumor cells ′apoptosis and enhan-cing NK cells.

OBJECTIVETo investigate the expression of microRNA-10a-5p (miR-10a) in laryngeal epithelial premalignant lesions (LEPL) and to analyze the correlations of its dysregulation with clinicopathologic parameters of LEPL.

METHODSAccording to the WHO classification (2005), 94 cases of LEPL were grouped into mild dysplasia (MID), moderate dysplasia (MOD), severe dysplasia (SD) and carcinoma in situ ( CIS). The expression of miR-10a in 94 cases of LEPL was detected by quantitative real-time polymerase chain reaction (qRT-PCR), and correlated with the clinical and follow-up data of all LEPL patients.

RESULTSmiR-10a was down-regulated in LEPL with increasing grade of dysplasia. There was significantly statistical difference between low-risk ( MID + MOD) and high-risk ( SD + CIS) lesion groups (P = 0.03). The linear regression analysis showed that miR-10a was correlated with grade and gender of LEPL (P < 0.05).

CONCLUSIONSDown regulation of miR-10a may be a useful molecular marker for grading of LEPL and diagnosis of early laryngeal cancer.
