Objective To analyze the cases of malignant tumors found in health examination in our hospital, and to determine the prevalence and characteristics of malignant tumor, and to provide evidence for the development of effective early screening program. Methods A total of 468673 subjects were included from those who had health checkup from July 2009 to December 2014 at the physical examination center. The subjects were between 4 to 96 years of age, with average age of (56.0±12.5) years. Of them, there were 278484 men, 190189 women. All cases found in the examination were confirmed with pathological testing. Prevalence comparison was done withχ2 test, statistic significance level was set at P<0.05. Results Totally 753 cases of malignant tumors were found in 6 consecutive years, with an overall prevalence rate at 160.7/100000. The prevalence rate increased yearly from 50.0/100000 for the first year, and 100.6/100000, 146.1/100000, 149.1/100000, 188.9/100000, 221.6/100000 thereafter. The difference between each 2 years was statistically significant (P<0.01). The top ten malignant tumors were liver cancer, cervical cancer, lung cancer, renal cell carcinoma, esophageal cancer, gastric cancer, colon cancer, breast cancer, leukemia and thyroid cancer. The prevalence rates of malignant tumors in the top three were liver cancer, lung cancer and kidney cancer for man and cervical cancer, lung cancer and breast cancer for women respectively. With the increase of age, the incidence of malignant tumor showed a rising trend, especially for the group of over 80 years old. But women with cervical cancer in the 50-years age group was the highest. Conclusion The number of cases of malignant tumors found in the health checkup population was rising. It is important to include early screening for malignant tumor in physical examination. We should also pay attention to the relevant departments, in order to improve the early cancer detection rate and decrease the morbidity and mortality of malignant tumors.

Inhibitor of growth 2 (INC2 ) is a member of INC family, and cooperates with p53 in regulating cell cycle, apoptosis, and aging. It can also facilitate chromatin remodeling and transcription regulating through histone modifications. Researches suggest that INC2 protein is an important factor in the genesis, metastasis and prognosis of many kinds of tumors. Resent studies indicate that INC2 can not be simply classified as oncogene or tumor suppressor. At present, the function of INC2 in tumorigenesis and tumor development involves interaction with varied molecules, but the mechanisms remain largely unknown, which still require further investigation.

To evaluate the clinical value of quantitative tissue velocity imaging (QTVI) in estimation of LV regional diastolic function in patients with coronary artery disease (CAD). The moving peak tissue velocity of LV wall in long axis direction during isovolumic relaxation (V IR ), early diastole (V E), atrial contraction (V A), and V E/V A ratio were measured and calculated by QTVI in 30 patients suffering from CAD and 40 healthy individuals. The results of QTVI were also compared with mitral valve peak flow velocities during early diastole (E), atrial contraction (A), and E/A ratio. In patients with CAD, V E was significantly lower than of nomal subjects( P

AIM　To study the positive inotropic effect of methyl polyglycoside (Mpg) on isolated guinea pig atria and its mechanism. METHODS　The effects of Mpg on contractility, beat rate of right atria, post-rest contraction and positive staircase phenomenon were observed in isolated guinea pig left and right atria. Na+-K+-ATPase activity of rat myocardial cell membrane was measured. RESULTS　Mpg (0.01～3 mmol*L-1) produced a concentration-dependent increase in myocardial contractility of atria and decrease in beat rate of right atria. Mpg markedly enhanced the post-rest contraction and the positive staircase phenomenon induced by increasing stimulation frequency in left atria, and inhibited Na+-K+-ATPase activity of rat myocardial cell membrane. CONCLUSION　The results suggest that Mpg can strengthen myocardial contractility of atria and decrease beat rate of right atria. Its positive inotropic effect may be related to inhibiting Na+-K+-ATPase activity of myocardial cell membrane, increasing the transmembrane influx of calcium and the amount of calcium released from intracellular stores.

Objective To compare the occurrence of the peripheral retinal degeneration in macular hole due to high myopia (＞-6.00 D) and trauma.Methods Data of 106 patients (106 eyes) with macular hole undergoing vitrectomy operation were analyzed,and they were divided into two groups according to myopic refractive degree:group A (68 eyes of 68 patients with high myopia) and group B (38 eyes of 38 patients with trauma).The peripheral retinas of all patients were examined carefully through preoperative three-mirror contact lens test and intraoperative the vitrectomy surgery.Results There were 52 eyes with peripheral retinal degeneration in group A,accounting for 76.47％,while group B had 8 eyes with peripheral retinal degeneration,accounting for 21.05％ in group B.The occurrence rates of peripheral retinal degeneration between the two groups approached significant difference (x2 =30.48,P =0.000).Among 52 eyes with retinal degeneration in the retina of the group A,non-oppressed whitening degeneration presented in 42 eyes,and the detection rate was 61.76％,lattice degeneration was in 44 eyes,with the detection rate of 64.71％,cystic degeneration in 19 eyes,with the detection rate of 27.94％ and other types of degeneration in 15 eyes,with the detection rate of 22.06％.There were 8 eyes with retinal degeneration in the retina of the group B,and non-oppressed whitening degeneration presented in 6 eyes,with the detection rate of 15.79％,lattice degeneration was in 7 eyes,with the detection rate of 18.42％,cystic degeneration in 4 eyes,with the detection rate of 10.53％ and other types of degeneration in 2 eyes,with the detection rate of 5.26％.Conclusion The occurrence rate of peripheral retinal degeneration in traumatic patients is obvious lower than that in patients with high myopia.

AIM To study the mechanism of effects about total flavones of choeropondias axillaris(TFC) to heart. METHODS The effects of TFC on contractility were investigated through acting on the guinea pig right ventricle papillary muscles. RESULTS ① TFC decreased both the contractility and contraction rate of papillary muscles. ②The quantity effect curve of CaCl 2 was shifted to right after giving TFC. ③TFC 30.4 ?mol?L -1 prolonged remarkably the functional refractory period (FRP) of guinea pig right ventricle papillary muscles, but exerted no effect on excitability. CONCLUSION TFC can inhibit the Ca 2+ influx into cell in a concentration dependent manner.

Objective:To investigate the effect and mechanism of miRNA-5193 (miR-5193) on the sensitivity of cervical cancer Caski cells to cisplatin.Methods:The expression of miR-5193 in cervical cancer cell lines C33A, SiHa, Caski and normal cervical cell line Ect1/E6E7 were determined by real-time fluorescent quantitative polymerase chain reaction (qRT-PCR). Caski cells were divided into control group (no transfection, normally cultured), miR-5193-negative control (miR-NC) group (transfected with miR-NC mimic), miR-5193 group (transfected with miR-5193 mimic), miR-NC+cisplatin group (transfected with miR-NC mimic and treated with 10 μg/ml cisplatin), miR-5193+cisplatin group (transfected with miR-5193 mimic and treated with 10 μg/ml cisplatin), miR-5193+cisplatin+NC group (cotransfected with Foxp3-negative control vector and miR-5193 mimic, and treated with 10 μg/ml cisplatin), and miR-5193+cisplatin+Foxp3 group (cotransfected with Foxp3 overexpression vector and miR-5193 mimic, and treated with 10 μg/ml cisplatin). Proliferation was detected by methyl thiazolyl tetrazolium (MTT), cell cycle was detected by PI single staining method, cell apoptosis was detected by Annexin V-FITC/PI double staining method, and expressions of CDK2, p27 and C-caspase-3 proteins in cells were detected by Western blot. Bioinformatics software was used to predict miR-5193 target genes, and the luciferase reporting system was used to identify the targeting relationship.Results:The relative expression of miR-5193 in cervical cancer C33A, SiHa and Caski cells was lower than that in normal cervical Ect1/E6E7 cells (0.56±0.06, 0.41±0.03, 0.23±0.02 vs. 1.00±0.10, all P < 0.05). Compared with the control group and miR-NC group, the cell proliferation activity (absorbance value) in miR-5193, miR-NC+cisplatin and miR-5193+cisplatin groups decreased (0.58±0.06, 0.59±0.07 vs. 0.38±0.04, 0.40±0.05, 0.23±0.02, all P < 0.05), the cell apoptosis rate increased [(2.5±0.2)%, (2.7±0.3)% vs. (12.6±1.2)%, (11.9±1.5)% , (18.9±1.7)%, all P < 0.05], and the proportion of cells in G 0/G 1 phase increased [(50.4±4.2)%, (51.3±6.3)% vs. (62.3±3.2)%, (61.9±5.8)%, (71.4±5.4)%, all P < 0.05]. The expression levels of p27 and C-caspase-3 proteins increased, and the expression level of CDK2 protein decreased. The software predicted that the target gene of miR-5193 was Foxp3, which was confirmed by the luciferase reporting system. Compared with the miR-5193+cisplatin+NC group, the cell proliferation activity (absorbance value) in miR-5193+ cisplatin+Foxp3 group increased (0.24±0.03 vs. 0.65±0.05, t = 21.094, P < 0.01), the proportion of cells in G 0/G 1 phase decreased [(71.0±6.4)% vs. (60.3±4.1)%, t = 4.196, P < 0.01], the apoptosis rate of cells decreased [(19.6±1.6)% vs. (11.5±1.2)%, t = 11.880, P < 0.01], the expression levels of p27 and C-caspase-3 proteins in cells decreased, and the expression levels of CDK2 and Foxp3 proteins increased. Conclusion:The miR-5193 may increase the sensitivity of cervical cancer Caski cells to cisplatin in vitro by targeted inhibition of the Foxp3 gene.
