Objective: To investigate the expression ofVEGF-Aand the correlation with the sentinel lymph nodes lymphangiogenesis and its metastasis in non-small cell lung cance(rNSCLC).Methods: The expression of VEGF-A was detected in 65 patients with NSCLC by SP immunohistochemistay. The expression of LYVE-1 was detected by immunofluorescence. The new lymphatic vessel density was counted by LYVE-1 and analyzed with clinicopathologic parameters. Results: The positive rate of VEGF-A was 72.3%(47/65),which was positively correlated with sentinel lympha nodes metastasis(r=0.453,P

0.05).Conclusion:QDs show no effect on cytobiological behavior of living MG-63 cells.

This study was designed to assess the immune protective effects of the vaccine strain of a precocious line of Eimeria necatrix with different doses and at different immunization times. The immunizations had a negative effect on weight gains of chickens to a certain degree but could be compensated during the “compensatory growth period” after immunity was established in the chickens. The number of oocysts excreted was positively correlated with the immunization dose. All the immunized chickens, whether they were immunized once or twice or immunized with different doses of sporulated oocysts, were able to resist attack from 1x105 virulent sporulated oocysts of E. necatrix. The lesion scoring showed that no significant difference existed in the chicken groups immunized with different doses (300 and 600) of sporulated oocysts. However, a difference existed in the immune homogeneity established in the different immunized groups, and two artificial immunizations were superior to one artificial immunization, indicating that two could extend the duration of oocyst excretion and allow more chances for the immunized chickens to become repeatedly infected.

Objective To investigate the relationship of change in hemodynamics of portal system and liver reserve of Chile-Pugh classification in patients with hepatocirrhosis.Methods Color Doppler ultrasound were applied to detect the inner diameter,average velocity of blood flow,quantity of blood flow of portal vein and splenic vein for 173 patients with post-hepatitis hepatocirrhosis(61 of Child grade A,53 of grade B,59 of grade C),which were sub- sequently compared with the healthy controls.Results In patients with hepatocirrhosis,the inner diameter of portal vein and splenic vein were widened,the average velocity of blood flow of portal vein and splenic vein were slowed down and the quantity of blood flow of splenic vein was increased,and the worse the damage of liver function was, the more obvious the change became.Conclusion The change in hemodynamics of portal system varies with the damage in liver function in patients with hepatocirrhosis.Measuring the hemodynamics of portal system is significant in determining the severity of the disease and the prognosis.

It has been demonstrated that certain members of cyclophilins (CyP) family are related to tomurigenesis, which might result from the role for Cyp in cell proliferation. Most members of Cyp family express specifically in tumor tissue in contrast to in normaltissue and cancer-brink tissue. It is possible that a novel approach to cancer therapy and diagnosis would be appeared through exploring the relationship between Cyp and tumor.

Objective To analyze the effect of Kangfuxin Liquidon on gingiva groove liquid interleukin 1β(IL-1β), prostaglandin E2 (PGE2), soluble adhesion molecule-1 (sICAM)in fixed orthodontic patients with gingivitis. Methods 96 cases of patients with fixed orthodontic gingivitis consult the draw method were divided into control group and experimental group, 48 cases in each group. The control group were treatedby gums clean, experimental group based on the control group were treattedby Kangfuxin Liquidon. The IL-1β, PGE2, sICAM-1 levels, periodontal status, the grade of swelling and pain, the clinical curative effect were compared between two groups. Results After treatment, the IL-1β, PGE2, sICAM levels of experimental group were lower than the control group (10.54±1.41) ng/L vs.(11.85±1.71)ng/L, (284.62±35.21) ng/L vs.(314.65±39.48)ng/L, (150.49±18.11) μg/L vs.(162.83±20.26) μg/L,the differences were statistically significant (P<0.05).The periodontal status, swelling and pain grading ofexperimental group were better than control group (P<0.05). Theeffective rate of experimental group was higher than the control group (95.83%vs.79.17%) (P<0.05). Conclusion Kangfuxin Liquidon can reduce fixed orthodontic patients with gingivitis gingiva groove IL-1β, PGE2, sICAM-1 levels, improve the periodontal status, relieve swelling and pain, improve the clinical curative effect.

After a description of the concept and meaning of big data, the application of big data in biomedical field was investigated, the changes in medical library functions were analyzed, the challenges to medical libraries were pointed in terms of their data, hardware infrastructures, software technologies, talents and service modes, and how to respond to the big data in medical libraries was proposed from the aspects of strengthening the external collabo-ration, co-developing cloud computing center, intensifying the construction of related organizations and talents, and changing the service modes.

Objective To investigate the incidence of abnormal thyroid function in pregnant women and explore the significance of thyroid function screening in early pregnancy. Methods We randomly selected 630 cases of pregnant women who received routine inspection in the obstetric clinic in our hospital, and gave them five items of thyroid function screening besides routine check at the same time. Then we statistically analyzed the test results, and followed up 61 cases of pregnant women with hypothyroidism or subclinical thyroid function (hypothyroidism) to learn the treatment and adverse pregnancy outcomes,so as tto explore the correlation between hypothyroidism, subclinical hypothyroidism and adverse pregnancy outcomes. Results In 630 cases of pregnant women,there were 8 cases of hyperthyroidism (1.3%),61 cases of hypothyroidism or subclinical hypothyroidism (9.7%),including 5 cases of hypothyroidism (0.8%), 56 cases of subclinical hypothyroidism (8.9%) .There was statistically significant difference in TSH and FT4 between hypothyroidism group and normal control group ( <0.01) .There was statistically significant difference in TSH,FT4 and TT4 between subclinical hypothyroidism group and normal control group ( <0.05) . In 61 cases of hypothyroidism and subclinical hypothyroidism, 39 patients received levothyroxine therapy,22 received no treatment. The incidence of adverse pregnancy outcomes in the treatment group was significantly lower than the untreated group ( <0.05) . Conclusion Thyroid function testing in 6-20 weeks in early pregnancy has important significance in timely founding gestational thyroid dysfunction, so it should be as routine examination project.

Nuclear factor-?B (NF-?B) is a nuclear transcription factor that regulates the expressions of multiple genes. It can be activated during cerebral ischemia; it is closely correlated with the inflammatory reaction and apoptosis during cerebral ischemia. NF-?B inhibitor ? (I?B?), an important inhibitor factor of NF-?B, can regulate the survival and death of neuron in the ischemia penumbra. Therefore, the inhibition of the degradation of I?B? and the prevention of the activation of NF-?B with drugs or molecular biological methods has become an important approach in study of the effect of NF-?B at present. Recent studies have indicated that I?B? itself may also participate in the regulation of apoptosis.
