Thyroid cancer is the most common malignancy in the endocrine system .In recent years ,the incidence of thyroid cancer has increased year by year ,which sparked people′s attention.With the development of thyroid cancer research ,it is found that cytokines play a key role in the occurrence and development of tumor .At present ,the cause of thyroid carcinoma and mechanism is not yet entirely clear ,however ,the occurrence of thyroid cancer is possiblely associated with the body regulating cellular immune dysfunction .Cytokines play an important role in the whole process ,in which the relationship between cytokines IFN -γ,IL-6 and thyroid carcinoma is closely related .

OBJECTIVE:To evaluate the effects of compound amino acids capsul es on hypoalbuminemia in patients with chronic renal failure undergoing hemodialysis.METHODS:30hemodialysis patients were selected to orally take2compound amino acids capsules(0.35g per capsule)twice daily for12weeks,renal and liver function and levels of serum albumin and pre-albumin were measured before and after the experiment.RESULTS:The levels of serum albumin and pre-albumin were increased significantly after the treatment,it were(30.5?4.6)g/L vs(35.9?7.1)g/L,and(213.0?46.9)mg/L vs(275.8?52.3)mg/L respectively(P

Objective To analyze and discuss the value and significance of coronary artery bypass grafts in the same period of heart valve replacement in the process of the coronary heart disease with heart valve disease treatment, in order to improve the effect of treatment and reduce the incidence of adverse events. Methods 60 cases with coronary heart disease with heart valve disease , which admitted in our hospital during February 2013-February 2015, were selected as the research objectaccording to random number table method and divided into the-experimental group and the control group , each group of 30 cases according to the principle of double blind control. The experimental group was given the coronary artery bypass grafts in the same period of heart valve replacement and the control group was given the coronary artery bypass grafts without heart valve replacement. The curative ef-fects of different schemes and effects on cardiac function after surgery of the two groups were compared. Results After statistical analysis found thatthe observation indexes of the control group was significantly increased compared with the experimental group, the difference was significant statistically significant (P<0.05). The postoperativecar-diac function indexes of the experimental group was significantly improved then control group , the difference was significant statistically significant (P<0.05). Conclusion Coronary heart disease with heart valve disease in the process of treatment can also take heart valve surgery combined coronary artery bypass surgery. By preoperative and postoperative symptomatic treatment, intraoperative protect myocardium, can effectively prevent and reduce the op-eration of various complications, which is worthy of clinical popularization and application.

Objective To investigate the survival rates of main malignant tumors in Nanhui district. Methods Total 5 783 cases, registered as new cases with malignant neoplasm from 2002 to 2004 in Nanhui, were followed up. Data was studied by survival analysis with SPSS 13.0 of life table and Kaplan -Meier. Results The average annual crude incidence of malignant tumors was 267.57 / 100 000, the World standardized incidence rate of 209.98 / 100 000. Cancer Incidence in the top five ranks followed by lung, liver, stomach, colon and esophageal cancer, the incidence was 43.06 / 100 000, 28.65 / 100 000, 26.82 / 100 000, 18.63 / 100 000 and 9.57 / 100 000, respectively. The difference of the survival rates between the top five cancers was remarkable. Survival rates of cancers among males from the lowest to the highest were liver, lung, esophagus, stomach and intestines. Survival rates of cancers among females from the lowest to the highest were of liver, lung, esophagus, stomach, intestines, cervical and breast. The male or female main cancer's relative survival rate droped along with the age rising. Conclusion The survival status was better in the patients with intestine cancers and female patients with breast cancer, but worse in patients with liver, ung and esophageal cancer.

Objective To study the expression of neural cell adhesion molecule CD 56 in the human lung cancer and its pathological significance. Methods 59 paraffin imbedded specimens of lung cancers were collected and human small cell lung cancer H128 cell line was cultured.The CD 56 expression in the lung cancer tissues and H128 cells was detected by immunohistochemical method. Results The expression of CD 56 was positive in 35 of 43 NSLC specimens, and the other specimens showed weakly positive staining. All 19 cases of the SCLC specimens showed CD 56 positive staining, 12 specimens of which were strongly positive. There was a significant difference in CD 56 expression between the SCLC and NSCLC. CD 56 was extensively expressed in H128 cells. Conclusion CD 56 might be an ideal tumour marker for SCLC.

Objective To explore the presence of common genetic alterations in retinoblastoma and to localize the altered genomic regions. Methods Genetic instability of chromosome 19, 20, 21, 22 and X of 15 microdissected retinoblastoma tumors were analyzed by the loss of heterozygosity (LOH) and microsatellite instability (MSI). Results Among the 15 patients with retinoblastoma, genome instability [LOH and(or) MSI] at one or more loci on the 5 chromosomes in 10 (67%), in which the loss of a single allele was more frequent in chromosomes 19 (33%) and 20 (27%) than in the other 3 chromosomes. High-frequency LOH between D19S902 and D19S571 suggested gene loci in the 19q13 region might be associated with tumor development in retina. According to the result of MSI, MSI occured at least in one subset of retinoblastoma. Conclusions Our results provide first evidence of LOH in chromosomes 19 and 20 in retinoblastoma and further support the presence of genome instability in retinoblastoma that may play an important role in the tumorigenesis or progression of retinoblastoma.

Objective To construct the recombinant plasmid carrying human sTNFR1 cDNA, and express sTNFR1 in E. Coli JM109. Methods Total RNA was extracted from Hela cells, and used as a template to amplify human sTNFR1 cDNA by RT-PCR. The PCR products were cloned into T vector, and then sTNFR1 cDNA fragment was subcloned into a prokaryotic expression plasmid pMAL-c2x. The recombinant plasmid was transferred into E. Coli JM109, and induced by IPTG to express fusion protein sTNFR1-MBP. sTNFR1-MBP was purified by amylose resin affinity chromatography(ARAC), and analyzed by SDS-PAGE. Results A 558 bp human sTNFR1 cDNA was amplified by RT-PCR, and successfully inserted into plasmid pMAL-c2x. sTNFR1-MBP was produced in E.Coli after IPTG induction, and a 66 KD sTNFR1-MBP was purified by ARAC. [WTHZ]Conclusion Recombinant plasmid carrying human sTNFR1 cDNA was successfully constructed and epxressed in E. Coli JM109.

Objective To explore the clinical features and treatment measures of the severe pneumonia in renal transplantation patients. Methods The clinical data of 27 patients with severe pneumonia following renal transplantation was retrospectively analyzed. Results The severe pneumonia in renal transplantation patients had the features such as earlier occurrence, speedy development and mixed infection of multi-bacteria. Twenty-two cases out of 27 patients (81.5%) were rescued successfully, and five cases died. Conclusion The patients with severe pneumonia following renal transplantation should be intensively observed and actively treated. The reasonable application of broad-spectrum antibiotics, breathing sustain and combined measures are the key points of successful treatment.

Objecfive To investigate the prevalence of Ureaplasma urealyticum(UU)and Mycoplasma hominis(MH)infections in urogenital tract and their sensitivities to drugs in Qinhuangdao area from 2006 to 2007.Methods UU and MH were detected by Mycoplasma IST kits in urine samples from 3062 patients suspected as urogenital tract infection and the sensitivity tests for 8 antimicrobial agents were performed.Results Mycolasmas were detected in 1262 patients from 3062 patients suspected as urogenital tract infection,in which 1037 were of UU infection,41 were of MH infection and 184 were of UU+MH infection.Both strains were sensitive to josamycin,doxycycline and tetracycline,but were less sensitive to ofloxacin and ciprofloxacin.Conclusions Drug resistance is increasing for Mycoplasma and sensitivity test is important in treatment of urogenital tract infection by Mycoplasma.
