Non-small cell lung cancer (NSCLC) is currently the leading cause of cancer-related deaths worldwide. Angiogenesis, the formation of new vasculature, is a complex and strictly regulated process that promotes metastasis and disease progression in lung cancer and other malignancies. Anti-angiogenic therapy is an anti-cancer strategy that targets the new vessels. Most anti-cancer agents used in the clinic include cytotoxic drugs, which target all rapidly dividing cells, resulting in severe adverse effects. These effects in-clude immunosuppression, intestinal problems, and hair loss. By contrast, anti-angiogenic agents theoretically exhibit fewer side effects because angiogenesis rarely occurs in healthy adults, except in the uterine endometrium. Various angiogenic factors may contribute to the regulation of angiogenesis in the individual tumor;thus, the proper selection of patients who may benefit from a specific therapy is important, considering the increasing number of clinically tested agents. This study provides an overview of angiogenic molecules cur-rently being investigated as prognostic and predictive biomarkers in NSCLC. Clinical examples are presented to show the rationales for investigating various biomarkers of pre-clinical studies.

Objective To explore the action mechanism of shenxiong glucose injection in treatment of acute spinal cord injury(SCI) through observing its effects on the recovery of motor function and the expression of aquaporin-4(AQP-4) in SCI rats.Methods Totally 90 healthy,aduh,Sprague-Dawley rats were randomly divided into a sham operation group (n=30),aSCI group (n=30) and a drug group (n=30).The SCI rat models in both the SCI group and the drup group were established aecording to the modified Allen's method,while the sham operation group was only given laminectomy.After the operation,the drug group was given intraperitoneal shenxiong glucose injection of 30 rnl/kg a day,while the other two groups were injected in the same way with normal saline.The neural function recovery,the pathological changes after SCI and the expressions of AQP-4 were observed 1,3,7,14 and 21 d after the operation using the Tarlov score,the hematoxylin and eosin staining,as well as immunofluorescence techniques and Western blotting.And the correlation of Tarlov scores with AQP-4 expressions was analyzed.Results No significant changes in Tarlov scores were observed in the sham operation group (P ＞ 0.05),while in the SCI group and the drug group,postoperative Tarlov scores decreased significantly.The hindlimb nerve function recovered to some degree with time in the SCI group and drug group.At 3,7,14 and 21 days after the operation,the Tarlov scores in the drug group were significantly higher than the SCI group (P ＜ 0.05).The drug group showed less severe pathological changes,with more residual neurons still visible of nucleoli than the SCI group 21 days after the operation.Compared with the sham operation group,the expression levels of AQP-4 were significantly higher in the SCI group and drug group at all the time points (P ＜ 0.05).However,the expression levels of AQP-4 in the drug group were significantly lower than the SCI group accordingly (P ＜ 0.05).The Tarlov scores were found to be significantly and negatively related to the AQP-4 protein expression levels 3 days(r =-0.523,P =0.003),7 days(r =-0.437,P=0.016),14 days(r=-0.417,P=0.022) and 21 days(r=-0.377,P=0.040)after the operation.Conclusion Injecting shenxiong with glucose can effectively promote the recovery of motor function after SCI,at least in rats.And its mechanism may be that the development of spinal cord edema is prevented and the secondary spinal cord injury alleviated by restraining the expressions of AQ P-4 in the injured areas.

Objective To observe the porcelain treated with Nd∶YAG laser irradiation and hydrofluoric acid (HF), and to explore the influence of integrated treatment of Nd ∶ YAG laser irradiation and HF etching in the bond strength of brackets to porcelain.Methods 48 metal ceramic prostheses were randomly divided into untreated control group,HF group,grooved treatment group,0.75W laser group,1.05W laser group,1.45W laser group. All samples were bonded to the brackets.After temperature cycling test,the shear bond strength (SBS)and tensile bond strength (TBS)were measured.Results There were significant differences in SBS and TBS between various surface treatment groups and untreated control group (P < 0.01).The SBS and TBS of brackets bonded in HF group was significantly higher than those in 1.05W laser and 1.45W laser groups (P <0.05).The SBS and TBS in 1.05W laser and 1.45W laser groups were higher than those in HF group (P <0.05).The SBS and TBS in 1.05W laser group were higher than those in other groups (P < 0.05).SBS showed positive correlation with TBS (r =0.426,P =0.000).Conclusion The use of Nd∶YAG laser irradiation with the energy parameter of 1.05W and HF could increase the bonding with formation of composite resin,and the more SBS,the more TBS.

Objective Effect of provenance on seed biological characteristics and seedling growth in Glycyrrhiza uralensis was studied to indicate the important role of provenance in standardization production of traditional Chinese medicinal materials.Methods Indexes such as 1 000-seed weight,water content,seed capsule penetration,germination percentage,and germination potency of the seeds from various resources were determined by general ways.Growth indexes of young seedling and one-year seedling were determined.Results Between Shanghaimiao provenance and Bayinwusu provenance,1 000-seed weight of G.uralensis in Shanghaimiao was bigger,which was 12.3 mg for the former and 11.7 mg for the latter;water penetration of seed capsule was stronger in Bayinwusu and conductance rate was twice as much as it in Shanghaimiao.Shanghaimiao seed bearing storage and seed vigor were stronger and hard seed rate was higher.Germination percentage and germination potency of untreated seed in Bayinwusu was higher than that of Shanghaimiao,but lower after treatment.Germination percentage and germination potency of smaller seeds was the highest between the two different provenances in both the untreated and treated seeds.In growth indexes of two provenances,young seedling got a significant and the most significant difference.Growth index in Shanghaimiao was higher a little,which didn't get to an obvious level.Conclusion The provenances have an effect on physical characteristics,seed capsule penetration,and germination properties;provenance and seed size have an obvious effect on young seedling growth but have not any effect on one-year seedling growth and biomass.

Objective To investigate the anti-microbial activity of genistein and its mechanism. Method The anti-microbial experiment was carried out by utilizing scanning and transmission electron microscope(SEM and TEM) ,and further analyzing the respiratory metabolism and change of SDS-PAGE protein spectra. Results Genistein could inhibit several kinds of bacteria obviously.The erose structures such as rugae and bubbles were observed on the surface of cells by SEM after 24h. Moreover,with TEM,we detected the shrinkage of cytoplasm,the plasmolyses,and then the breach of wall and membrane along with the outflow of protoplasm in Staphylococcus aureus treated with genistein for 4h,14h and 24h respectively. Notablely the respiratory inhibition experiment revealed that the genistein mainly inhibits the TCA cycle of bacteria. Besides,the SDS-PAGE elucidated that the total expression of proteins was decreased in the cell treated with genistein,and especially the larger proteins were reduced with 90.1%. Conclusion Genistein showed obvious anti-microbial activity to Staphylococcus aureus. It could destroy the integrity of cell wall and membrane,prevent the respiratory metabolism and protein synthesis of the bacteria.

The association between the polymorphism of SLC17A1 gene and hyperuricemia in Uyghur population in Xinjiang region was explored by Chi-square test.A total of 1 024 patients with hyperuricemia and 1 033 healthy volunteers were included.The genotype frequencies of CC,CT,and Tr in hyperuricemia and healthy controls were 24.9％,53.14％,21.96％ and 29.7％,47.52％,22.77％,respectively.There was statistical difference in SLC17A1 rs9467596 genotype frequencies between hyperuricemia cases and controls (x2 =7.492,P =0.024).CT genotype could increase the risk of hyperuricemia compared with CC genotype (OR =1.334,95％ CI 1.082-1.644).No statistical significance among the genotypes was found in age,body mass index,blood pressure,blood glucose,triglyceride,total cholesterol,High-density lipoprotein-cholesterol,low-density lipoprotein-Cholesterd,blood urea nitrogen,and Creatinine.The polymorphism of rs9467596 in SLC17A1 may be a genetic marker to assess risk of hyperuricemia among Xinjiang Uyghur population.

Objective To investigate the relationship between glucokinase regulator protein ( GCKR) gene polymorphism rs780094 and hyperuricemia in Uygur in Xinjiang. Methods A case-control study including 1 026 patients with hyperuricemia and 1 030 normal subjects was conducted. All the subjects were genotyped for GCKR gene rs780094 by Sequenom MassARRAY system. The results of rs780094 genotype and allele frequency between hyperuricemia group and control group were compared. The associations of different genotypes of rs780094 with blood pressure, blood lipid, and blood glucose were analyzed. Logistic regression analysis was used to analyse the relationship between polymorphism of rs780094 and hyperuricemia in Uygur in Xinjiang. Results The distributions of three genotypes(G/G, A/G, A/A) and two allele frequency (G and A) in GCKR rs780094 revealed statistical difference ( P<0. 05 ) between hyperuricemia group and control group. A tendency toward association with hyperuricemia was observed under dominant model(OR=1. 295, 95%CI 1. 078~1. 554,P=0. 006) and recessive model(OR=1. 284, 95% CI 1. 024 ~1. 611,P=0. 030). The levels of systolic blood pressure, diastolic blood pressure, and total cholesterol were lower in hyperuricemia group with GCKR gene rs780094 loci GG genotype than those with AA+AG genotype. After adjusting confounding factors which had significant difference in the single factor analysis, logistic regression analysis showed that rs780094 A/A and A/G might be risk factors of hyperuricemia in Uygur in Xinjiang (OR=1. 355,95% CI 1. 094 ~1. 679,P=0. 005). Conclusion The GCKR rs780094 is associated with hyperuricemia in Uygur in Xinjiang. The A/A and A/G genotype of the GCKR rs780094 may increase the risk of hyperuricemia.
