Objective To screen proteins binding with interferon?(IFN?)from human hepatic cDNA libraty by yeast-two hybrid technique.Methods The IFN?gene was amplified by polymerase chain reaction(PCR)and constructed into pGBKT7 vector as the bait plasmid in yeast-two hybrid system3,pGBKT7-IFN?was then transfected into yeast AH109.The transfected yeast were mated with yeast Y187 containing liver cDNA library plasmid in 2?YPDA medium.Diploid yeast was plated on synthetic dropout nutrient medium(SD/-Trp Leu-His-Ade)and synthetic dropout nutrient medium(SD/-Trp-Leu-His-Ade)containing X-?-gal for selecting.After plasmid extracting and en- zyme cutting analysis,the blue colonies were performed sequence analysis,the results were analyzed by bioinformatics.Results IFN?gene was successfully cloned and expressed in yeast cells.Thirty- four positive colonies were obtained using yeast-two hybrid technique.After sequence analysis,eight clones were found may have a binding effect with IFN protein.Conclusions IFN?genes was success- ful cloned and eight proteins that could bind with IFN?protein were also screened.

ObjectiveTo investigate the relationship between tumor necrosis factor (TNF) α308,TNF-β252 genotypes and serum TNF-α and TNF-β levels in patients with gastric cancer (GC).MethodsA total of 57 pathological diagnosed GC patients were collected,of which 49 cases were from Zhongnan Hospital of Wuhan University and 8 cases were from Tumor Hospital of Hubei Province.Another 18 age and sex matched healthy controls were enrolled at the same time.The TNF-α308 and TNF -β252 polymorphism was genotyped by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP).The serum TNF-α and TNF-β levels of 57 GC patients and 18 healthy controls were measured by ELISA.The difference of TNF serum level in different TNF genotypes of GC and the difference between GC patients and the healthy controls was analyzed.Its relationship with clinical pathological characters was also analyzed.Results With TNF-α308 genotype,GA were 6 cases and GG were 51 cases.With TNF-β252 genotype,GG were 17 cases,GA and AA each were 20 cases.The serum TNF-α level of GC patients was significant higher than that of healthy controls (median 445 × 10-3 μg/L vs 5 × 10-3 μg/L,P<0.05),and the serum level of each TNF-α308 andTNF-β 252 genotypes was significant higher than that of healthy controls (P<0.05).However there was no statistical significance in TNF -β level compared with healthy controls (P>0.05).In addition,the serum TNF-α levels of the TNF-α308G/TNF-β252G and TNF-α308G/TNF β252A haplotypes in GC patients were significant higher than those of the healthy controls (P<0.05),and the increase like serum TNF-α level was associated with the patients'age and lymph node metastasis (P<0.05).The TNF-β level in patients with TNF-α308A and TNF-β252G high-risk haplotypes showed a significant relation with smoking history (P< 0.05). Conclusions Serum TNF-α level of GC patients was significantly higher,however there was no significant association between the increase and TNF-α308 and TNF-β252 genotypes.The serum TNF-α levels of TNF-α308G/TNF-β252G and TNF-α308G/TNF-β252A haplotypes in GC patients were significant higher,and associated with the patients'age and lympb node metastasis.It was indicated that TNF haplotypes may have certain impact on the TNF expression and clinical subtypes in GC.

Because of the changed metabolic behaviors of cancer cells, tumor cells uptake a corresponding larger amount of glucose in physiological condition when compared with normal cells. And they were prone to metabolize glucose for generating energy in anaerobic glycolysis ways in order to grow quickly. Anaerobic glycolysis consumes more glucose than aerobic way when the same amount of energy is obtained, which also results in large demand of glucose in tumor cells. This review briefly describes therapy methods related to characteristic mentioned above, and summarizes the research progress of drugs, diagnostic reagents and carriers conjugated with glucose, glucose derivatives or other kinds of sugars for cancer targeting. Furthermore, typically relative research reports from 2012 till now were listed and analyzed.

Objective To analyze if there are membrane estrogen receptors(ER)in endometrial carcinoma and if there is some relationship between membrane ER and nuclear ER.Methods The cell membrane and total cell ER?and ER?expressions of high and moderate differentiation endometrial carcinoma cells(Ishikawa and HEC-1A cells)were analyzed.Intermittent immunofluorescence dyeing and fluorescent microscopy were carried out with the ceils treated with polyformaldehyde and Triton X-100. Intermittent immunofluorescence dyeing and flow cytometry were carried out with the live cells and the cells treated with Triton X-100 respectively.Results There were fluorescences on the membrane of the Ishikawa and HEC-1A cells which were treated with polyformaldehyde.When the cells were treated with Triton X- 100,the fluorescences were also seen inside the cells.The fluorescence intensity of ER?and ER?in Ishikawa cell membrane(1.09?0.21,1.27?0.33)was stronger than the control,but there were no significant differences(P>0.05).When treated with Triton X-100,the total cell fluorescence intensity of ER?and ER?in Ishikawa cell(4.21?0.34,4.69?1.96)was stronger than the membrane(P<0.05). The ER?and ER?fluorescence intensity of HEC-1A cell membrane(1.58?0.13,1.49?0.04)were stronger than the control(P<0.05).The fluorescence intensity of ER?and ER?of the HEC-1A cell (2.34?0.33,2.52?0.15)was stronger than the membrane also(P<0.05).The membrane ER?fluorescence intensity of Ishikawa was lower than HEC-1A(P=0.028).But the total cell ER?fluorescence intensity of Ishikawa was higher than HEC-1A(P=0.002).Conclusions There are membrane ER on endometrial carcinoma cells Ishikawa and HEC-1A.The membrane ER must have some similarity to the nuclear receptor.There is no direct correlation between the quantity of the membrane ER and nuclear ER.

AIM To determine the effect of L-arginin e on cerebral blood perfusion following subarachnoid hemorrhage(SAH) in rats. METHODS Endovascular perforating SAH models were replicated in Wista r rats, and animals were divided into sham-operated group, SAH group and SAH+ L-arginine group. Dynamic changes of regional cerebral blood flow (rCBF) with in 24 hours were measured and serum nitric oxide(NO, NO - 2/NO - 3)levels at different time points within 24 hours were detected. Mean arterial blood pre ssure and blood gas were monitored during the experiment. RESULTS No obvious change in physiological parameters in the three groups was observed . rCBF and serum nitric oxide level at every time point after operation in SAH g roup were lower than those in sham-operated group. Pathological alterations abo ve in SAH+L-arginine group were less obvious than those in SAH group. CONCLUSION L-arginine, by antagonizing the decrease of nitric oxi de, exerts protective effect on secondary cerebral ischemia following SAH.

Objective To probe the value of ultrasound in detection of malignant foci among multiple thyroid nodules. Methods Ultrasonograms of 83 patients with pathologically confirmed thyroid cancer combined with benign nodules were analyzed.Results Among 83 patients of thyroid carcinoma, 89 malignant and 87 benign nodules were detected with ultrasound. Significant differences of two-dimensional ultrasounic signs including low echoes, border fuzzy, micro-calcification and rear echo attenuation were found bteween malignant and benign nodules (P<0.01). There were significant differences in the grade Ⅱ, Ⅲ blood flow between malignant and benign ones (P<0.01). Of 89 malignant nodules, small thyroid carcinoma with diameter ≤1 cm accounted for 52.81% (47/89), and ultrasound diagnostic rate of all cancer nodules was 67.42% (60/89).Conclusion Ultrasounic characteristics including low echoes, border fuzzy, micro-calcification, rear echo attenuation and internal rich blood flow contribute to differentiate the thyroid microcarcinoma from multinodules.In particular, the microcarcinoma should not be ignored.
